tongue, resulting in a poor air intake efficiency of the cross-flow air
channel, a poor air flow
performance in the cross-flow air channel, and a poor pressure resistance of
the cross-flow air
channel, and thus resulting in a low air volume of the cross-flow air channel.

[0043] The following disclosure provides many different
embodiments or examples for
implementing different structures of the present disclosure. To simplify the
present disclosure,
specific example components and arrangements are described below. They are, of
course,
merely examples and are not intended to limit the present disclosure. In

This repetition
CA 03237453 2024- 5-6

is for the purpose of simplicity and clarity and does not in itself dictate a
relationship between
the various embodiments and/or arrangements discussed. In addition, the
present disclosure
provides examples of various specific processes and materials, but a person
skilled in the art
may recognize the applicability of other processes and/or the use of other
materials.
[0044] Hereinafter, an air channel assembly according to an embodiment of
the present
disclosure will be described with reference to the accompanying drawings.
[0045] As shown in FIGS. 1 and 2, the air channel assembly
includes an upstream air
channel part 1 and a cross-flow air channel part 2, wherein the upstream air
channel part 1
defines an upstream air channel 11; in a cross section of the cross-flow air
channel part 2, the
cross-flow air channel part 2 includes a first air channel wall 21 and a
second air channel wall
22 arranged at intervals; wherein a cross-flow air channel 23 is formed
between the first air
channel wall 21 and the second air channel wall 22 and communicates downstream
of the
upstream air channel 11; the first air channel wall 21 includes a volute
tongue section 211, and
the cross-flow air channel 23 includes a fan mounting cavity 231 formed
between a volute
tongue windward surface 2a of the volute tongue section 211 and the second air
channel wall
22; a part of the first air channel wall 21 between the volute tongue tip 2b
of the volute tongue
section 211 and the air channel outlet 232 of the cross-flow air channel 23 is
an air outlet
section 212. For example, the volute tongue section 211 further includes a
volute tongue
deflecting surface 2c, and the volute tongue deflecting surface 2c and the
volute tongue
windward surface 2a are connected smoothly by a curved surface to form the
volute tongue
tip 2b.
[0046] As shown in FIGS. 1 and 2, the fan mounting cavity 231 is
configured to mount a
cross-flow fan 5, wherein the cross section of the cross-flow air channel part
2 refers to a
cross section taken through the cross-flow air channel part 2 using a plane
perpendicular to a
central axis of the cross-flow fan 5. When the cross-flow fan 5 rotates, an
airflow is induced
to flow through the upstream air channel 11, and the airflow flowing out of
the upstream air
channel 11 enters the cross-flow air channel 23 from an air channel inlet of
the cross-flow air
channel 23, and then is discharged out of the cross-flow air channel 23
through the air channel
outlet 232. The fan mounting cavity 231 is located at the air channel inlet of
the cross-flow air
channel 23.
CA 03237453 2024- 5-6

[0047] As shown in FIGS. 1 and 2, the air channel assembly has an
air supplement path 3,
an air inlet 31 of the air supplement path 3 is located at the air outlet
section 212, and the air
inlet 31 is in communication with a region of the cross-flow air channel 23
located
downstream of the fan mounting cavity 231, such as a first region 233 shown in
FIG. 1. An
air outlet 32 of the air supplement path 3 is provided between the volute
tongue section 211
and the upstream air channel part 1, and the air outlet is open towards the
outside of the
cross-flow air channel 23 and is in communication with the upstream air
channel 11, so that
the air outlet 32 can discharge the airflow to the upstream air channel 11
outside the
cross-flow air channel 23 at a position relatively close to the volute tongue
section 211
upstream of the fan mounting cavity 231, and the airflow then flows from the
upstream air
channel 11 to the cross-flow air channel 23, i.e. the airflow discharged from
the air outlet 32
can first enter the upstream air channel 11 and then enter the cross-flow air
channel 23.
[0048] It should be noted that the direction of the air outlet 32
is not limited as long as the
air outlet 32 is not open towards the inside of the cross-flow air channel 23.
It should be noted
that upstream of a feature described herein refers to the location before the
airflow enters the
feature, and downstream of the feature refers to the location after the
airflow flows out of the
feature.
[0049] Thus, an air pressure of the air outlet 32 can be less
than an air pressure of the air
inlet 31, and a part of the airflow flowing out from the cross-flow fan 5,
when reaching the air
inlet 31, can be sucked into the air inlet 31 under the action of the air
pressure, and then is
discharged outside of the cross-flow air channel 23 via the air outlet 32 so
as to be located
upstream the outside of the fan mounting cavity 231, and then enters the cross-
flow air
channel 23 via the air channel inlet of the cross-flow air channel 23, and
then enters the fan
mounting cavity 231, so as to control an eccentric vortex in the cross-flow
air channel 23 at a
position in the fan mounting cavity 231 close to the volute tongue section
211, effectively
improving the air intake efficiency of the cross-flow air channel 23, thereby
improving a
pressure resistance of the cross-flow air channel 23, and further improving an
air volume of
the cross-flow air channel 23.
[0050] The applicant has inventively found in the research that
when the air outlet 32 of
the air supplement path 3 is arranged relatively close to the volute tongue
section 211, and is
CA 03237453 2024- 5-6
8
open towards the outside of the cross-flow air channel 23 and is in
communication with the
upstream air channel 11, the airflow discharged from the air outlet 32 can
firstly enter the
upstream air channel 11, and then be sucked into the cross-flow air channel
23; at this time, in
conjunction with FIG. 3, the airflow can more effectively impact the edge of
the eccentric
vortex in the circumferential direction or tangential direction of the
eccentric vortex, thereby
improving the driving efficiency of the eccentric vortex, improving the air
intake efficiency of
the cross-flow air channel 23, and improving the air flow performance in the
cross-flow air
channel 23, increasing the pressure resistance of the cross-flow air channel
23, thereby
increasing the air volume of the cross-flow air channel 23.
[0051] Moreover, the flow field formed at the volute tongue section 211
changes with
different rotation speeds of the cross-flow fan 5, and the airflow in the air
supplement path 3
can change adaptively with the rotation speeds, so that the eccentric vortex
can be controlled
stably and adaptively, and the air intake efficiency of the cross-flow air
channel 23 can be
improved more effectively, the air flow performance in the cross-flow air
channel 23 can be
improved, the pressure resistance performance of the cross-flow air channel 23
can be
improved, and the air volume of the cross-flow air channel 23 can be improved.
[0052] In addition, it is worth mentioning that the applicant has
inventively found in the
research that if the air outlet 32 of the air supplement path 3 is provided on
the volute tongue
windward surface 2a and is open towards the inside of the cross-flow air
channel 23 (an
example is not shown in the figure), the air supplement path 3 is directly in
communication
with the inside of the cross-flow air channel 23, and the airflow discharged
from the air
supplement path 3 directly flows from the volute tongue windward surface 2a to
a small space
between the volute tongue windward surface 2a and the cross-flow fan 5 in the
cross-flow air
channel 23, and directly impacts the eccentric vortex in the radial direction
of the eccentric
vortex in general, in this way, not only the eccentric vortex cannot be
effectively controlled,
but also the eccentric vortex more obstructs the airflow in the cross-flow air
channel 23,
resulting in a more poor pressure resistance of the cross-flow air channel 23
and a reduced air
volume of the cross-flow air channel 23.
[0053] In short, according to the air channel assembly of an
embodiment of the present
disclosure, by providing the air supplement path 3, the air supplement is able
to change with
CA 03237453 2024- 5-6
9
the rotation speed of the cross-flow fan 5 and the self-characteristics of the
volute tongue
section 211, the flow characteristics of the eccentric vortex are adaptively
adjusted to improve
the air intake efficiency of the cross-flow air channel 23, thereby improving
the flow
performance of the cross-flow air channel 23 and improving the air volume of
the cross-flow
air channel 23.
[0054] In some embodiments of the present disclosure, a heat
exchanger 6 may be
provided in the upstream air channel 11, the upstream air channel 11 includes
a heat
exchanger mounting cavity 111 for mounting of the heat exchanger 6. As shown
in FIGS. 1
and 2, when the cross-flow fan 5 rotates, the airflow is induced to flow
through the upstream
air channel 11. The airflow enters the upstream air channel 11 to exchange
heat with the heat
exchanger 6, then flows to the cross-flow air channel 23, and then is
discharged outside of the
cross-flow air channel 23 through the air channel outlet 232.
[0055] It should be noted that a specific type of the heat
exchanger 6 is not limited as long
as it has a heat exchange function, and the heat exchanger 6 may include, for
example, a
tube-fin heat exchanger, a microchannel heat exchanger, a resistance heat
exchanger, etc. In
addition, in some embodiments, the upstream air channel 11 may not be provided
with a heat
exchanger 6, such as nothing may be provided in the upstream air channel 11;
or the upstream
air channel 11 may be provided with other functional elements, such as an air
deflector, a
filter, a purifier, a humidifier, etc.
[0056] As shown in FIGS. 1 and 2, when the upstream air channel 11 includes
the heat
exchanger mounting cavity 111 for mounting of the heat exchanger 6, the air
outlet 32 may be
provided between the volute tongue section 211 and the heat exchanger mounting
cavity 111
and in communication with a region of the upstream air channel 11 located
downstream of the
heat exchanger mounting cavity 111, such as a second region 112 shown in FIG.
1.
[0057] It will be appreciated that the airflow flowing out from the cross-
flow fan 5 may
first reach the first region 233 before reaching the air channel outlet 232,
and the airflow
flowing out from the heat exchanger 6 may first reach the second region 112
before entering
the cross-flow air channel 23. The pressure at the first region 233 is greater
than the pressure
at the second region 112, so that the airflow at the air inlet 31 may be
sucked into the air
supplement path 3 under the action of the air pressure and discharged into the
second region
CA 03237453 2024- 5-6
112 through the air outlet 32 and then into the cross-flow air channel 23.
[0058] In short, since the air pressure of the air outlet 32 is
less than the air pressure of the
air inlet 31, a part of the airflow flowing out from the cross-flow fan 5,
when reaching the air
inlet 31, can be sucked into the air inlet 31 under the action of the air
pressure, and then is
discharged to a position downstream of the heat exchanger 6 in the upstream
air channel 11
via the air outlet 32, so as to control the eccentric vortex in the cross-flow
air channel 23 at a
position in the fan mounting cavity 231 close to the volute tongue section 211
when the
airflow is subsequently sucked into the cross-flow air channel 23, thereby
effectively
improving the air intake efficiency of the cross-flow air channel 23, and
improving the
pressure resistance performance of the cross-flow air channel 23, and further
improving the
air volume of the cross-flow air channel 23.
[0059] In some of the split wall-mounted air conditioners in the
related art, in order to
improve the heat exchange capacity, a heat exchange device using integrated C-
type fin (such
as the heat exchanger 6 shown in FIG. 1) can improve the heat exchange
capacity by more
than 10% with respect to a heat exchange device using V-type fin. However, the
pressure loss
of the C-type fin increases with respect to the fluid performance of the air
channel. For
example, it has been tested that the outlet cross-section of the C-type fin
has a maximum air
velocity of 3.5 m/s, and the outlet cross-section of the V-type fin has a
maximum air velocity
of 4 m/s. The total pressure drop of the C-type fin is 17.7 Pa, and the total
pressure drop of the
V-type fin is 12.7 Pa. It can be seen therefrom that the pressure drop of the
C-type fin is larger
and the pressure loss of the C-type fin is larger, resulting in an increase in
the air intake
resistance and an unsmooth air intake. Further, in a cooling state, water will
be accumulated
on the fins, resulting in a further increase in air intake resistance and a
more unsmooth air
intake, and at the same rotation speed, the air volume will be sharply reduced
and the local air
velocity will be too small.
[0060] When the split wall-mounted air conditioner uses the cross-
flow fan, when the
cross-flow fan is operated, an eccentric vortex (e.g. at X shown in FIG. 4) is
formed near the
volute tongue of the cross-flow fan to reduce the pressure resistance of the
cross-flow air
channel. Furthermore, a low-pressure vortex (e.g. at Y shown in FIG. 4) is
easily formed near
one end of the volute tongue outside the air channel inlet of the cross-flow
air channel due to
CA 03237453 2024- 5-6
11
the flow characteristics of the cross-flow air channel to reduce the air
intake efficiency of the
cross-flow air channel. Furthermore, due to some other requirements of the
split
wall-mounted air conditioner, a structural end wall, such as a water receiving
plate, is usually
provided at the low-pressure vortex, thereby further deteriorating the air
intake efficiency of
the cross-flow air channel, making the flow of the cross-flow airflow
unstable, and affecting
the air intake efficiency of the cross-flow air channel.
[0061] However, according to the air channel assembly of an
embodiment of the present
disclosure, by providing the air supplement path 3, the air supplement can
adaptively adjust
the flow characteristics of the eccentric vortex and the low-pressure vortex
with the rotation
speed of the cross-flow fan 5 and the self-characteristics of the volute
tongue section 211,
thereby effectively improving the air intake efficiency of the cross-flow air
channel 23,
improving the air flow performance in the cross-flow air channel 23, improving
the pressure
resistance of the cross-flow air channel 23 and improving the air volume of
the cross-flow air
channel 23.
[0062] In some embodiments of the present disclosure, the air channel
assembly may
include: a downstream air channel part defining a downstream heat exchange air
channel. The
downstream heat exchange air channel communicates downstream of the cross-flow
air
channel. The downstream heat exchange air channel includes a downstream
mounting cavity
for mounting of a heat exchange device, including but not limited to the heat
exchanger 6
described above. Thus, when the cross-flow fan 5 rotates, the airflow is
induced to flow
through the upstream air channel 11, then flow through the cross-flow air
channel 23, then
enter the downstream heat exchange air channel. The airflow enters the
downstream heat
exchange air channel to exchange heat with the heat exchange device, and then
is discharged
out of the downstream heat exchange air channel. At this time, the upstream
air channel 11
may not be provided with nothing therein; or the upstream air channel 11 may
be provided
with functional members, such as an air deflector, a filter, a purifier, a
humidifier, a heat
exchanger 6, etc. Additionally, in other embodiments, the air channel assembly
may not
include the downstream air channel part.
[0063] It is worth noting that the air inlet 31 and the air
outlet 32 of the air supplement
path 3 may overlap each other (for example, a plate may be punched directly as
the air
CA 03237453 2024- 5-6
12
supplement path 3, and the perforation hole is both the air inlet 31 and the
air outlet 32). Of
course, the present disclosure is not limited thereto, and the air inlet 31
and the air outlet 32 of
the air supplement path 3 may also not overlap each other, for example, the
air inlet 31 and
the air outlet 32 may be in communication with each other via an air
supplement channel 33,
or a sealed cavity 34, or an air guide hard pipe, or an air guide hose, etc.
[0064] In some embodiments of the present disclosure, the air
outlet 32 of the air
supplement path 3 may be located on a side of the volute tongue windward
surface 2a facing
away from the fan mounting cavity 231. It should be noted that reference
herein to "the side
facing away from the fan mounting cavity 231" refers to a side facing away
from the
cross-flow fan 5. The reference herein to feature I being located on a side of
feature II facing
away from the fan mounting cavity 231 means that a radial distance between
feature I and the
cross-flow fan 5 is greater than a radial distance between feature II and the
cross-flow fan 5.
[0065] Therefore, "the air outlet 32 of the air supplement path 3
is located on the side of
the volute tongue windward surface 2a facing away from the fan mounting cavity
231" means
that the air outlet 32 of the air supplement path 3 is located near the volute
tongue windward
surface 2a, and the radial distance between the air outlet 32 and the cross-
flow fan 5 is greater
than the radial distance between the volute tongue windward surface 2a and the
cross-flow fan
5. Thus, it is possible to prevent the air outlet 32 of the air supplement
path 3 from being
located on a surface of a side of the volute tongue windward surface 2a facing
the fan
mounting cavity 231. Thus, it is possible to ensure that the air outlet 32 is
located on the side
of the volute tongue windward surface 2a facing away from the fan mounting
cavity 231, so
that it is possible to prevent the airflow flowing out of the air outlet 32
from directly flowing
out of the volute tongue windward surface 2a and directly entering the cross-
flow air channel
23. In fact, the airflow flowing out of the air outlet 32 can first enter the
upstream air channel
11 outside the cross-flow air channel 23 and then enter the cross-flow air
channel 23. Thus, it
is more advantageous to have a positive influence on the air intake efficiency
of the
cross-flow air channel 23. Of course, the present disclosure is not limited
thereto. In other
embodiments of the present disclosure, the relative positional relationship
between the air
outlet 32 and the volute tongue windward surface 2a may be provided to be less
clear, which
will not be described in detail herein.
CA 03237453 2024- 5-6

[0066] In an embodiment of the present disclosure, the number and
the forming position
of the air outlet 32 are not limited. For example, the air outlet 32 includes
at least one of a first
outlet formed on the first air channel wall 21, a second outlet formed on the
upstream air
channel part 1, and a third outlet formed at a gap between the first air
channel wall 21 and the
upstream air channel part 1. That is, the air outlet 32 may be formed at at
least one of the first
air channel wall 21, the upstream air channel part 1, and a gap between the
first air channel
wall 21 and the upstream air channel part 1. Thus, the air outlet 32 can be
designed
accordingly for different types of machines to increase the application range
and simplify the
processing.
[0067] Alternatively, at least one air outlet 32 is provided, and when the
at least one air
outlet 32 includes a plurality of air outlets 32, the plurality of air outlets
32 are successively
arranged at intervals in a direction facing away from the fan mounting cavity
231, and any
one of the plurality of air outlets 32 may be an opening or may include a
plurality of
sub-outlets arranged at intervals in the axial direction across the cross-flow
air channel 23. By
the same reasoning, at least one air inlet 31 is provided, and when the at
least one air inlet 31
includes a plurality of air inlets 31, the plurality of air inlets 31 are
successively arranged at
intervals in the air discharge direction, and any one of the plurality of air
inlets 31 may be an
opening or may include a plurality of sub-inlets arranged at intervals in the
axial direction of
the cross-flow air channel 23.
[0068] When the at least one air outlet 32 includes a plurality of air
outlets 32, for
example, the air outlet 32 may include at least two of the first outlet, the
second outlet and the
third outlet, and the number of each air outlet 32 is at least one, and for
another example, the
air outlet 32 may include one of the first outlet, the second outlet and the
third outlet, and the
number of such air outlets 32 is at least two.
[0069] For example, one or more first outlets is provided, and when the one
or more first
outlets includes a plurality of first outlets, the plurality of first outlets
are successively
arranged at intervals in a direction facing away from the cross-flow fan 5,
and any one of the
plurality of first outlets may be an opening or may include a plurality of
first sub-outlets
arranged at intervals in the axial direction of the cross-flow air channel 23.
[0070] For example, one or more second outlets is provided, and when the
one or more
CA 03237453 2024- 5-6
14
second outlets includes a plurality of second outlets, the plurality of second
outlets are
successively arranged at intervals in a direction facing away from the cross-
flow fan 5, and
any one of the plurality of second outlets may be an opening or may include a
plurality of
second sub-outlets arranged at intervals in the axial direction of the cross-
flow air channel 23.
[0071] For example, the third outlet may be an opening or may include a
plurality of third
sub-outlets arranged at intervals in the axial direction of the cross-flow air
channel 23.
[0072] For example, in some embodiments, the volute tongue
section 211 further includes
a volute tongue extension surface 2d, wherein the volute tongue extension
surface 2d extends
from an end of the volute tongue windward surface 2a facing away from the
volute tongue tip
2b in a direction facing away from the fan mounting cavity 231 (in conjunction
with FIGS. 1
and 2). The first outlet is provided on the volute tongue extension surface
2d. Thus, the first
outlet can be directly machined on the volute tongue section 211, which is
convenient to
machine and reduce costs. Furthermore, the first outlet can be far away from
the cross-flow
fan 5 compared with the volute tongue windward surface 2a, thereby improving
the driving
efficiency of the eccentric vortex and improving the air intake efficiency
more effectively.
[0073] For example, in some embodiments, the volute tongue
section 211 further includes
a volute tongue extension surface 2d, wherein the volute tongue extension
surface 2d extends
from an end of the volute tongue windward surface 2a facing away from the
volute tongue tip
2b in a direction facing away from the fan mounting cavity 231 (in conjunction
with FIGS. 1
and 2). The third outlet is defined between an end of the volute tongue
extension surface 2d
facing away from the volute tongue windward surface 2a and the upstream air
channel part 1.
Thus, the formation of the third outlet is simple, the processing is
convenient, the cost is
reduced. Furthermore, the third outlet can be far away from the cross-flow fan
5 compared
with the volute tongue windward surface 2a, thereby improving the driving
efficiency of the
eccentric vortex and improving the air intake efficiency more effectively.
[0074] For example, in some embodiments, as shown in FIGS. 7 and
8, the third outlet is
defined between an end of the volute windward surface 2a facing away from the
volute
tongue tip 2b and the upstream air channel part 1. Thus, the formation of the
third outlet is
simple, the processing is convenient, and the cost is reduced.
[0075] In some embodiments of the present disclosure, as shown in FIGS. 1
and 2, a
CA 03237453 2024- 5-6
centerline of the cross-flow air channel 23 extends in a transverse direction,
i.e. a central axis
of the cross-flow fan 5 is provided horizontally or substantially
horizontally. The upstream air
channel part 1 includes a water receiving section 12 defining a water
receiving tank 121, at
least a part of the water receiving section 12 is located below and between
the heat exchanger
mounting cavity 111 and the fan mounting cavity 231 (e.g. the second region
112 shown in
FIG. 1). The air outlet 32 is located on a side of the water receiving section
12 close to the
volute tongue section 211 (e.g. the right side of the water receiving section
12 shown in FIGS.
1 and 2).
[0076] As a result, it is not easy for the air supplement to blow
out the water in the water
receiving tank 121, thereby alleviating the problem of air blowing water out.
In addition, by
providing the air outlet 32 on the side of the water receiving section 12
close to the volute
tongue section 211, it is ensured that the airflow discharged from the air
outlet 32 can more
effectively control the eccentric vortex in the cross-flow air channel 23
close to the volute
tongue section 211, thereby improving the pressure resistance of the cross-
flow air channel 23,
and further improving the air volume of the cross-flow air channel 23.
[0077] As shown in FIGS. 1 and 2, the air outlet 32 may be formed
at at least one of the
volute tongue section 211, the water receiving section 12, and a gap between
the volute
tongue section 211 and the water receiving section 12. When the air outlet 32
is formed at the
volute tongue section 211 (for example, the air outlet 32 being provided at
the
above-mentioned volute tongue extension surface 2d), the air outlet 32 can be
an alternative
embodiment of the above-mentioned first outlet; when the air outlet 32 is
formed at the water
receiving section 12, the air outlet 32 can be an alternative embodiment of
the
above-mentioned second outlet; when the air outlet 32 is formed at the gap
between the volute
tongue section 211 and the water receiving section 12 (for example, the air
outlet 32 being
provided between an end of the above-mentioned volute tongue extension surface
2d facing
away from the volute tongue windward surface 2a and the water receiving
section 12, as
shown in FIG. 9; or the air outlet 32 being provided between an end of the
above-mentioned
volute tongue windward surface 2a facing away from the volute tongue tip 2b
and the water
receiving section 12, as shown in FIGS. 7 and 8), the air outlet 32 can be an
alternative
embodiment of the above-mentioned third outlet. In this way, it is convenient
to process and
CA 03237453 2024- 5-6
16
manufacture, and it is possible to simply and effectively ensure that the air
outlet 32 is located
on the side of the water receiving section 12 close to the volute tongue
section 211, so as to
ensure that the air supplement is not easy to blow out the water in the water
receiving tank
121, thereby alleviating the problem of air blowing water out.
[0078] In some embodiments of the present disclosure, as shown in FIGS. 2,
5, and 6, the
air supplement path 3 includes an air supplement channel 33 for communication
between the
air outlet 32 and the air inlet 31. The air supplement channel 33 extends in a
direction from
the air inlet 31 to the air outlet 32. The air outlet 32, the air inlet 31,
and the air supplement
channel 33 communicate in one-to-one correspondence. That is, one air
supplement channel
33 is only in communication with one air inlet 31 and one air outlet 32, so
that one air outlet
32, one air inlet 31, and one air supplement channel 33 constitute one air
supplement group.
In one air supplement group, the air outlet 32 is in communication with the
air inlet 31
through the air supplement channel 33. The air supplement path 3 includes at
least one air
supplement group. As a result, it is possible to improve air supplement
circulation efficiency
and reduce the air supplement loss.
[0079] Alternatively, a width of the air supplement channel 33 is
smaller than a radius of
the cross-flow fan 5, so that a more effective air supplement effect can be
achieved.
Alternatively, the width of the air supplement channel 33 is less than 2 times
the width of any
one of the air inlet 31 and the air outlet 32 and is more than 0.5 times the
width of at least one
of the air inlet 31 and the air outlet 32. As a result, it is only necessary
to provide a
small-sized air supplement channel 33, the rapid air supplement and airflow
guide can be
achieved, and thus improving the air supplement efficiency, reducing the air
volume loss and
ensuring the air volume.
[0080] Referring to FIG. 2, the width dl of the air inlet 31
refers to an opening size of the
air inlet 31 in a cross section perpendicular to the center line of the cross-
flow air channel 23.
The width d2 of the air outlet 32 refers to an opening size of the air outlet
32 in the cross
section perpendicular to the center line of the cross-flow air channel 23. The
width dimension
d of the air supplement channel 33 refers to the width of the air supplement
channel 33 in the
cross section perpendicular to the center line of the cross-flow air channel
23.
[0081] For example, in some embodiments, the air supplement channel 33 may
have a
CA 03237453 2024- 5-6
17
width ranging from 3 mm to 7 mm, e.g. 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, etc. In
this way,
the air supplement effect and the overall air volume may be better balanced.
[0082] It is worth noting that the width of the air supplement
channel 33 may be a
constant width or a gradual width, for example, the air supplement channel 33
may be formed
to be tapered in the direction from the air inlet 31 to the air outlet 32 so
that the air volume
may be increased. Further, for example, the air supplement channel 33 may be
formed to
expand gradually in the direction from the air inlet 31 to the air outlet 32,
so that noise can be
reduced. When the width of the air supplement channel 33 is the constant
width, both the air
volume and the noise can be considered, and the processing can be facilitated.
[0083] In some embodiments, when the cross-flow fan is used in the split
wall-mounted
air conditioner, in order to balance the cooling and heating effects, in the
cooling mode, the air
is allowed to blow up as much as possible, and in the heating mode, the air is
allowed to blow
down as much as possible, and at the same time, the air at the air outlet of
the air conditioner
is prevented from flowing back to the air inlet of the air conditioner; when
the air channel
outlet of the air channel is designed, the upper mold line of the pressure
expanding section is
consciously pressed down, resulting in a low-speed region locally formed in
the pressure
expanding section, and the low-speed region is insufficient to overcome the
static pressure
inside the air channel; and the air outside the air channel outlet may flow
back into the air
channel outlet, causing a pulsating surge sound to occur, affecting using
experience of a user.
[0084] It is worth noting that the shape of the air supplement channel 33
is not limited, for
example, the air supplement channel 33 may extend from the air inlet 31 to the
air outlet 32
along a straight line, or a curved line, or a combination of a straight line
and a straight line, or
a combination of a straight line and a curved line. That is, in the cross-
section of the
cross-flow air channel part 2, the shape of the extension center line of the
air supplement
channel 33 is not limited, and may be a straight line (in a case where the air
supplement
channel 33 is a straight line type channel, such as shown in FIG. 2), or a
curved line (in a case
where the air supplement channel 33 is an arc type channel, such as shown in
FIG. 5, or a
wave type channel, such as shown in FIG. 6, etc.), or a combination of a
straight line and a
straight line (in a case where the air supplement channel 33 is a broken line
type channel, or a
sawtooth type channel, etc.), or a combination of a straight line and a curved
line, etc.
CA 03237453 2024- 5-6
18
[0085] Wherein the air supplement channel 33 extending along a
straight line can improve
the control ability to the eccentric vortex, the air supplement impact speed
is enhanced, and
the air volume is increased at the same rotation speed of the cross-flow fan
5; the air
supplement channel 33 extending along a non-straight line, such as a curved
line (e.g. an arc
line, a wavy line), a sawtooth line, etc. can slow down the impact speed of
the air supplement,
with little change in air volume and noise, but can stabilize the flow of the
airflow.
[0086] In some embodiments of the present disclosure, the air
supplement path 3 only
includes the air supplement channel 33, but does not include the sealed cavity
34 described
later; in this case, the number of the air outlet 32, the air inlet 31 and the
air supplement
channel 33 may be the same, and the air outlet 32, the air inlet 31 and the
air supplement
channel 33 communicate in one-to-one correspondence. That is to say, the
number of the air
outlet 32, the air inlet 31 and the air supplement channel 33 is the same and
may all be N,
wherein N is an integer greater than or equal to 1, and each air outlet 32 is
in communication
with a corresponding air inlet 31 via a corresponding air supplement channel
33 respectively.
[0087] As described above, any one of the air outlets 32 may be an opening
or include a
plurality of sub-outlets arranged at intervals in the axial direction of the
cross-flow air channel
23, and thus the air supplement channel 33 in one air supplement group may be
in
communication with the plurality of sub-outlets at the same time. In addition,
any one of the
air inlets 31 may an opening only, or may include a plurality of sub-inlets
arranged at intervals
in the axial direction of the cross cross-flow air channel 23, and thus the
air supplement
channel 33 in one air supplement group may be in communication with the
plurality of
sub-inlets at the same time.
[0088] Any one of the air supplement channels 33 may be one
channel, or may include a
plurality of sub-channels arranged at intervals in the axial direction of the
cross-flow air
channel 23. The direction in which the cross-flow air channel 23 extends in
the axial direction
of the cross-flow air channel 23 is not limited, depending on the relative
positions of the air
inlet 31 and the air outlet 32 in communication with the air supplement
channel 33. For
example, in a longitudinal section of the cross-flow air channel part 2
(wherein the
longitudinal section of the cross-flow air channel part 2 refers to a
longitudinal section taken
through the cross-flow air channel part 2 using a plane passing through the
central axis of the
CA 03237453 2024- 5-6
19
cross-flow fan 5), the air outlet 32, the air inlet 31, and the air supplement
channel 33, which
are in communication with each other, have positions in the axial direction of
the cross-flow
air channel 23 corresponding to each other. That is to say, the air supplement
channel 33 is
projected forward to the longitudinal section, the air outlet 32 is projected
forward to the
longitudinal section, and the air inlet 31 is projected forward to the
longitudinal section, and
the three forward projections have same range as in the axial direction of the
cross-flow fan 5.
In this way, the airflow entering the air inlet 31 can be discharged out from
the air outlet 32
without being offset in the axial direction of the cross-flow air channel 23,
thereby further
simplifying the structure of the air supplement channel 33, reducing the
difficulty of
processing, and improving the air supplement efficiency.
[0089] Of course, the present disclosure is not limited thereto,
and in other embodiments
of the present disclosure, the positions of the air outlet 32, the air inlet
31, and the air
supplement channel 33 in the axial direction of the cross-flow air channel 23
may not
correspond to each other, for example, the air outlet 32 corresponds to one
end of the
cross-flow air channel 23 in the axial direction, the air inlet 31 corresponds
to the other end of
the cross-flow air channel 23 in the axial direction, etc. In this way, the
airflow entering the
air inlet 31 needs to be offset in the axial direction of the cross-flow air
channel 23 to be
discharged from the air outlet 32, which will not be described in detail
herein.
[0090] In some embodiments of the present disclosure, as shown in
FIG. 10, the air
supplement path 3 may include a sealed cavity 34 for communication between the
air outlet
32 and the air inlet 31, the sealed cavity 34 is in communication with the
plurality of air
outlets 32 simultaneously and/or with the plurality of air inlets 31
simultaneously. Thus,
different design requirements can be satisfied and a flexible design can be
achieved.
[0091] For example, alternatively, one sealed cavity 34 is in
communication with one air
inlet 31 while being in communication with a plurality of air outlets 32. In
this case, the
airflow may enter the sealed cavity 34 from one air inlet 31 and then be
discharged in a
plurality of streams from the plurality of air outlets 32. As another example,
alternatively, one
sealed cavity 34 is in communication with a plurality of air inlets 31 while
being in
communication with one air outlet 32. In this case, the airflow may enter the
sealed cavity 34
from the plurality of air inlets 31 and then be discharged from one air outlet
32. As another
CA 03237453 2024- 5-6
example, alternatively, one sealed cavity 34 is in communication with a
plurality of air inlets
31 while being in communication with a plurality of air outlets 32. In this
case, the airflow
may enter the sealed cavity 34 from the plurality of air inlets 31 and then be
discharged in a
plurality of streams from the plurality of air outlets 32.
[0092] It is worth noting that the air supplement path 3 may include only
one of the air
supplement channel 33 and the sealed cavity 34, or may include both of the air
supplement
channel 33 and the sealed cavity 34. Thereby, a flexible design can be
achieved. For example,
in some alternative embodiments, the air supplement path 3 includes only the
sealed cavity 34
and does not include the air supplement channel 33, and in this case, all of
the air outlets 32
and all of the air inlets 31 may be in communication with the same sealed
cavity 34, thereby
simplifying the design and reducing the processing difficulty.
[0093] In some alternative embodiments of the present disclosure,
the sealed cavity 34
may not have a directionality of extension as compared to the air supplement
channel 33, the
width of the sealed cavity 34 relative to the air supplement channel 33 may be
slightly larger,
for example, the width of at least a part of the sealed cavity 34 may be
greater than twice the
width of at least one of the air inlet 31 and the air outlet 32, etc. whereby
a flexible design
may be achieved.
[0094] In addition, in some embodiments, if the volume of the
sealed cavity 34 is large,
thermal insulation material 9 may be added to the sealed container 34 to
enhance thermal
insulation, anti-condensation, etc.
[0095] In some embodiments of the present disclosure, as shown in
FIGS. 8 and 9, the air
channel assembly may further include an air deflector 4 provided at the air
outlet 32 on a side
of the air outlet 32 facing away from the fan mounting cavity 231. As a
result, the direction of
the airflow flowing out from the air outlet 32 can be more effectively
controlled by the air
deflector 4, the performance of the eccentric vortex can be more effectively
controlled, the air
supplement waste can be reduced, and the air volume can be ensured.
[0096] It is worth noting that the structural shape of the air
deflector 4 is not limited, for
example, it can be a cambered air deflector or a planar air deflector, and
when the air deflector
4 is a cambered air deflector, the airflow guiding effect can be improved, and
when the air
deflector 4 is a planar air deflector, the processing difficulty can be
reduced.
CA 03237453 2024- 5-6
21
[0097] Further, it should be noted that the air deflector 4 may
be in a fixed form or in a
movable form.
[0098] For example, when the air deflector 4 is in a fixed form,
the mounting angle can be
designed in advance (for example, a certain angle can be deviated), so that it
can more
effectively control the direction of the airflow flowing out from the air
outlet 32, more
effectively control the performance of the eccentric vortex, reduce the air
supplement waste
and ensure the air volume.
[0099] For example, when the air deflector 4 is in a movable
form, alternatively, the air
deflector 4 may be elastically swingable so as to be swing between a direction
close to the air
outlet 32 and a direction facing away from the air outlet 32, i.e. the air
deflector 4 may be
elastically swingable via an elastic part, so that the eccentric vortex can be
adaptively
controlled at different rotation speeds by using the elasticity of the elastic
part, i.e. automatic
elastic swing may be used to adaptively control the eccentric vortex, thereby
reducing costs
and providing a good adjustable effect.
[00100] For example, when the air deflector 4 is in a movable form, or
alternatively, the air
deflector 4 can be swingable in a driven manner so as to swing between a
direction close to
the air outlet 32 and a direction facing away from the air outlet 32, i.e.,
the swinging of the air
deflector 4 can be controlled in a driven manner by providing a driving
mechanism, so that
the performance of the eccentric vortex can be controlled more effectively at
different rotation
speeds by means of the control of the driving mechanism, so as to reduce air
supplement
waste and ensure air volume. For example, when the air deflector 4 swings in
the direction
facing away from the air outlet 32, the noise can be reduced, and when the air
deflector 4
swings in the direction closer to the air outlet 32, the pressure resistance
can be increased and
the air volume can be increased.
[00101] In some embodiments of the present disclosure, as shown in FIGS. 1 and
2, the air
inlet 31 is provided at the end of the air outlet section 212 near the volute
tongue tip 2b, for
example, the distance between the air inlet 31 and the volute tongue tip 2b is
less than one
quarter of the length of the air outlet section 212, and as shown in FIGS. 11
and 12, the
airflow at the volute tongue tip 2b has a lower air velocity and a higher
pressure, and thus the
air inlet 31 is provided close to the volute tongue tip 2b, so that the
airflow can be better
CA 03237453 2024- 5-6
22
sucked into the air inlet 31 under the action of the pressure, reducing the
air volume loss. For
example, alternatively, the air outlet section 212 includes a volute tongue
air deflecting
surface 2c extending along a curved line and a pressure expanding surface 2e
extending along
a straight line, and the air inlet 31 is provided near a position where the
volute tongue air
deflecting surface 2c meets the pressure expanding surface 2e, or near the
volute tongue tip 2b.
Thereby, it is ensured that the airflow can be sucked into the air inlet 31
more efficiently.
[00102] Hereinafter, an air conditioning device 100 according to an embodiment
of the
present disclosure will be described.
[00103] As shown in FIG. 1, the air conditioning device 100 may include: the
air channel
assembly according to any one of the embodiments of the present disclosure,
and a cross-flow
fan 5 provided in the fan mounting cavity 231. Thus, it is possible to
increase the ventilation
amount of the air conditioning device 100.
[00104] It is worth noting that the specific type of the air conditioning
device 100
according to an embodiment of the present disclosure is not limited, and may
be an air
conditioner, an air purifier, a humidifier, or the like. Further, the type of
the air conditioner is
not limited, and may be, for example, a duct type air conditioner, a split-
type air conditioner
indoor unit (e.g. an air conditioner cabinet machine, a wall-mounted air
conditioner), an
integrated air conditioner (e.g. a window air conditioner, a portable air
conditioner, a mobile
air conditioner), etc.
[00105] For example, in some embodiments, when the air conditioning device 100
is a duct
type air conditioner, the heat exchange device may be provided downstream of
cross-flow air
channel 23. When the air conditioning device 100 is a split-type air
conditioner indoor unit,
the heat exchanger 6 may be provided upstream of the cross-flow air channel
23, which will
not be described in detail herein.
[00106] Having determined the type of the air conditioning device 100
according to
embodiments of the present disclosure, other configurations and operations of
the air
conditioning device 100 are known to a person skilled in the art and will not
be described in

[00108] Further, the terms "first" and "second" are used for descriptive
purposes only and
are not to be construed as indicating or implying relative importance or
implicitly indicating
the number of technical features indicated. Thus, a feature defined as "first"
or "second" may
explicitly or implicitly include one or more of the stated features. In the
description of the
present disclosure, "a plurality of" refers to two or more unless specifically
defined otherwise.
[00109] In this disclosure, unless expressly specified and limited otherwise,
the terms
"mounted", "coupled", "connected", "secured", and the like are to be construed
broadly, e.g.
either fixedly or detachably, or integrally connected; it can be directly
coupled or indirectly
coupled through an intermediate medium, and can be the communication between
two
elements or the interaction relationship between two elements. The specific
meaning of the
above terms in the present disclosure can be understood by a person skilled in
the art as the
case may be.
[00110] In the present disclosure, unless expressly specified and limited
otherwise, the first
feature "above" or "below" the second feature may be that the first and second
features are in
direct contact, or that the first and second features are in indirect contact
through an
intermediary. Further, the first feature being "on", "above" and "over" the
second feature may
be directly above or obliquely above the second feature or merely indicate
that the first feature
is at a higher level than the second feature. The first feature being "under",
"below" and
"beneath" the second feature may be that the first feature is directly below
or obliquely below
the second feature, or simply that the first feature has a smaller level than
the second feature.
