BLADELESS FAN CAPABLE OF ADJUSTING OUTLET AIR
TEMPERATURE
FIELD OF THE INVENTION
[0001] The invention relates to the technical field of fans, in particular to
a bladeless fan
capable of adjusting the outlet air temperature.
BACKGROUND OF THE INVENTION
[0002] Electric fans are widely used in various occasions in daily life and
are common
electric apparatuses used by people for cooling in hot summer. With the
development of science
and technology, the variety of the electric fans is more and more. People have
developed more
practical bladeless fans. However, there is still a problem that the electric
fans are usually only
suitable for use in hot weather and not suitable for use in cold weather as
the working principle
of the electric fans is for the body temperature of users or the ambient
temperature to be
reduced by the formation of large airflow, and thus the utilization rate of
the fans is low.
[0003] The Chinese patent Application No. 201110225536.X discloses an electric
fan
provided with heaters. The electric fan generates heat by electrifying the
heaters. When the
airflow blown out by the electric fan is heated when passing through the
heaters, the
temperature is increased and hot-blast air is blown out. However, the heating
temperature of the
air cannot be adjusted and controlled in the proposal, so users cannot adjust
the hot-blast air at
specific temperature blown out by the electric fan according to respective
demands, thus the
practicality of the electric fan is not strong.
SUMMARY OF THE INVENTION

art and provide a
bladeless fan capable of adjusting the outlet air temperature and having
strong practicality.

CA 02786350 2012-08-15
[0026] As illustrated in Fig. 1, the touch-screen controller 7 is provided
with a power button
for controlling the on-off of the fan, a rotation button for controlling the
horizontal rotation of
the fan, a temperature adjustment button for adjusting the outlet air
temperature and a timing
button for controlling the timed shut-down of the fan. The functions such as
the on-off of a
power supply for the fan, the rotation of the fan, the adjustment of the
outlet air temperature and
the timed shut-down of the fan can be realized by touching the buttons
respectively. Of course,
the buttons can be added or removed according to actual conditions. For
example, the timing
button can be not set in the case that the timing function of the fan is not
required. Likewise,
corresponding buttons can be added in the case that other functions are
required.
[0027] A mounting housing 11 is arranged inside the air outlet device 2, and
the heaters 6 are
arranged inside the mounting housing 11. A large amount of heat can be
generated in the case
that the heaters 6 are electrified, so a housing made of heat-resistant
materials is required for
fixing the heaters 6. In the invention, the heaters 6 are arranged inside
cavities 111 of the
mounting housing 11.
[0028] Wherein, the mounting housing 11 comprises the hollowed-out cavities
111 for
receiving the heaters 6; ribs 13 for fixing the heaters 6 are arranged inside
the cavities 111; and
the inside of the mounting housing 11 is clamped with the air outlet device 2.
In the invention,
the front and rear sides of the cavities 111 are completely opened, and the
central sections of the
cavities 111 are provided with the ribs 13 for fixing the heaters 6. By
adoption of the structure,
not only the structure of the mounting housing 11 is simpler and the resources
are conserved but
also the heat generated by the heaters 6 can be more easily conducted out and
the heating
efficiency of the fan can be improved.
[0029] As illustrated in Fig. 2, air inlet duct supports 8 are arranged
between the air outlet
device 2 and the rotating portion 4 and articulated with two outer central
sections of the air
outlet device 2 respectively, and airflow channels are formed among the
rotating portion 4, the
air inlet duct supports 8 and the air outlet device 2. The angle of the air
outlet device 2 can be
adjusted through the air inlet duct supports 8, so that the requirement on
different outlet air
CA 02786350 2012-08-15
angles can be met.
[0030] Wherein, an angle positioning ring 9 is arranged on the outer sidewall
of the air outlet
device 2, and both ends of the air inlet duct supports 8 are sleeved on the
angle positioning ring
9 of which the pendulum angle is between 0 and 175 DEG. The range of the
pendulum angle of
the air outlet device 2 is wider by the addition of the angle positioning ring
9, thus the
practicality is strong.
[0031] Wherein, an air outlet 10 is arranged on the inner circumference of the
air outlet
device 2; the caliber of the air outlet 10 is gradually increased from the
inside to the outside;
and the inner surface of the air outlet device 2 is an inclined plane. Not
only the air blown out
from the air outlet 10 can be smoothly blown out along the smooth inclined
plane but also the
air outlet direction can be appropriately adjusted.
[0032] Wherein, a motor shield 16 and a motor pedestal 17 are also arranged
inside the fixing
portion 3; the motor 15 is arranged between the motor shield 16 and the motor
pedestal 17; and
wire clamp blocks 19 are arranged outside the motor shield 16. As illustrated
in Fig. 6, a
plurality of the wire clamp blocks 19 are arranged outside the motor shield
16. The wiring
direction of each wire clamp block 19 is perpendicular to the horizontal
direction, so that wires
led out from the motor 15 can be favorably fixed and perpendicularly clamped
on the wire
clamp blocks 19, thus the positioning effect is good and the practicality is
strong.
[0033] Wherein, heat reflection plates are arranged inside the air outlet
device 2 at positions
corresponding to the heaters 6. The heat reflection plates have two functions:
one is for the heat
generated by the heaters 6 to be reflected and emitted to the direction of the
air outlet 10, so that
the heat can be quickly conducted out; and the other is for a housing of the
air outlet device 2 to
be protected, so that the damage caused by overhigh temperature can be
avoided.
[0034] Second Embodiment:
[0035] As illustrated in Figs. 4 and 5, the differences between the embodiment
and the first
embodiment are as follows: the mounting housing 11 of the embodiment comprises
an upper
connecting portion 112, a lower connecting portion 113 and the two cavities
111; the tops of the
6
CA 02786350 2012-08-15
two cavities 111 are connected with the upper connecting portion 112
respectively; and the
bottoms of the two cavities 111 are connected with the lower connecting
portion 113
respectively.
[0036] Wherein, the upper connecting portion 112, the lower connecting portion
113 and the
two cavities 111 are integrated into the mounting housing 11; a plurality of
clamp hooks 14
clamped with the air outlet device 2 are arranged inside the mounting housing
11; and the shape
and dimension of the mounting housing 11 are matched with those of the air
outlet device 2.
The mounting housing 11 can be firmly fixed on the air outlet device 2 through
a plurality of
the clamp hooks 14, so that the heaters 6 can be fixed. Wiring openings 12 for
electric wires to
pass through are arranged outside the cavities 111, so that the electric wires
can be conveniently
led out from the cavities 111 at both sides of the air outlet device 2 and
connected with control
switches at the bottom of the air outlet device 2.
[0037] Other parts of the embodiments are the same with those of the first
embodiment and
not described in detail here.
[0038] It should be finally noted that the above embodiments are only used for
illustrating the
technical proposal of the invention but not for limiting the scope of
protection of the invention.
Although detailed description is given to the invention with the preferred
embodiments, it
should be understood by those skilled in the art that modifications or
equivalent replacements
can be made on the technical proposal of the invention without departing from
the essence and
scope of the technical proposal of the invention.
