Best Mode for Carrying out the Invention
[17] Hereinafter, a reflector and a gas oven range including the reflector
will be explained
in detail with reference to the accompanying drawings according to a first em-
bodiment.
[18] Fig. 1 is a perspective view illustrating a gas oven range 1 according to
a first em-
bodiment, and Fig. 2 is an exploded perspective view illustrating an upper
burner 500
and a reflector 600 according to the first embodiment.
[19] Referring to Fig. 1, the oven range 1 includes a cook top part 100, an
oven part 200, a
drawer part 300, and a control part 400. The cook top part 100, the oven part
200, and
the drawer part 300 are disposed at upper, middle, and lower regions of a main
body 10
of the oven range 1, respectively. The control part 400 is disposed on the top
of the
CA 02732369 2011-01-27
3
WO 2010/013930 PCT/KR2009/004200
main body 10 at a rear edge portion corresponding to a rear side of the cook
top part
100.
[201 In more detail, the cook top part 100 includes a plurality of cook-top
burners 110.
Each of the cook-top burners 110 can generate a flame by burning a gaseous
fuel to
directly heat a container in which food is placed. A plurality of knobs 120
are disposed
on a front end portion of the cook top part 100. The knobs 120 are used to
close, open,
or adjust valves (not shown) for starting, stopping, or adjusting supply of a
gaseous
fuel to the cook-top burners 110.
[211 The oven part 200 includes an oven cavity 210 provided inside the main
body 10. An
oven chamber 211 is provided in the oven cavity 210. In the oven chamber 211,
food is
cooked. A burner chamber (not shown) is provided in the oven cavity 210 under
the
oven chamber 211 to install a lower burner (not shown).
[221 The oven chamber 211 can be selectively closed and opened by using an
oven door
220. The oven door 220 is a pull-down door of which the top end can be rotated
up and
down about the lower end. A door handle 221 is provided on a front upper
portion of
the oven door 220 so that a user can easily rotate the oven door 220 using the
door
handle 221.
[231 A container in which food is contained can be stored in the drawer part
300 at a pre-
determined temperature. The drawer part 300 includes a drawer 310 in which a
container can be placed.
[241 A manipulation signal can be input (generated) through the control part
400 for
operating the oven range 1, specifically, at least one of the cook top part
100, the oven
part 200, and the drawer part 300. In addition, the control part 400 displays
in-
formation about operational conditions of the oven range 1.
[251 Fig. 2 shows the upper burner 500 that is disposed at an upper side of
the oven
chamber 211. The upper burner 500 is used to burn a gaseous fuel to directly
heat food
placed in the oven chamber 211 by radiant heat from above. In the current em-
bodiment, the upper burner 500 includes three combustion parts 510 that have a
fork
shape elongated in a left-to-right direction (not shown) or preferably in a
front-to-back
direction of the oven chamber 211.
[261 Referring to Figs. 2 and 3, the reflector 600 includes a reflection part
610, exhaust
holes 620, and fixing flanges 630. The reflector 600 is disposed between the
ceiling of
the oven chamber 211 and the upper burner 500. When a gaseous fuel is burned
at the
upper burner 500, the reflector 600 reflects heat from flames downwardly
toward food
placed in the oven chamber 211. In addition, when a gaseous fuel is burned at
the
upper burner 500, combustion gas is guided by the reflector 600 to a space
above the
reflector 600, that is, between the ceiling of the oven chamber 211 and the
reflector
600.

WO 2010/013930 PCT/KR2009/004200
[271 Flames and heat generated from the upper burner 500 are guided and
reflected
toward food placed in the oven chamber 211 substantially by the reflection
part 610.
The reflection part 610 is formed by bending a plate having a predetermined
area in an
approximate W-shape (cross sectional shape). In more detail, the reflection
part 610
includes a plurality of first connection parts 611, oblique parts 613, and
second
connection parts 615.
[281 Each of the first connection parts 611 has a predetermined lateral width
and is
located directly above the combustion part 510 in parallel with the combustion
part
10.The number of the first connection parts 611 is determined according to the
number of the combustion parts 510. The oblique parts 613 are sloped upwardly
from
both sides of the first connection part 611 at a predetermined angle. The
second
connection part 615 is disposed between neighboring two of the oblique parts
613 to
connect ends of the oblique parts 613. When a gaseous fuel is burned at the
upper
burner 500, combustion gas is collected in a space formed by the second
connection
part 615 and two oblique parts 613 connected to the second connection part
615, and
then discharged through the exhaust holes 620.
[291 The fixing flanges 630 are disposed on corners of the top surface of the
reflection
part 610. The fixing flanges 630 are used to fix the reflection part 610 to
the ceiling of
the oven chamber 211. The fixing flanges 630 may be formed at the corners of
the re-
flection part 610 by cutting and upwardly bending the first connection parts
611 and
the oblique parts 613.
[301 When a gaseous fuel is burned at the upper burner 500, combustion gas is
collected
between the upper burner 500 and the reflection part 610, that is, in spaces
formed by
the second connection part 615 and the oblique parts 613 connected to the
second
connection part 615. Then, the combustion gas is discharged to a space between
the
ceiling of the oven chamber 211 and the reflection part 610 through the
exhaust holes
620. For this end, the exhaust holes 620 are formed into an elongated shape by
partially cutting out the second connection parts 615 in longitudinal
direction thereof,
i.e. in the prefered embodiment is a front-to-back direction.
[311 Operations of the reflector 600 and the oven range 1 including the
reflector 600 will
now be described with reference to the accompanying drawings according to the
first
embodiment.
[321 Fig. 3 is a vertical sectional view illustrating reflection of flames and
exhaustion of
combustion gas at the reflector 600 according to the first embodiment.
[331 A user can input a manipulation signal by using the control part 400 for
cooking food
using the oven part 200. If a manipulation signal is input through the control
part 400,
the upper burner 500 (and the lower burner) is operated to cook food in the
oven
chamber 211.
CA 02732369 2011-01-27

WO 2010/013930 PCT/KR2009/004200
[34] In detail, gas and air are supplied to the upper burner 500, and flames
are generated
by combustion of the gas and air. Then, food is cooked in the oven chamber 211
by
flames and heat generated at the upper burner 500. At this time, the reflector
600
guides flames and reflects heat generated by combustion of gas at the upper
burner 500
toward the food placed in the oven chamber 211. Thus, the reflector 600
reflects the
heat radiated upwardly from the flames back the food located below the burner.
In
addition, since the reflector 600 guides and reflects the flames, it is heated
by the
flames directly and by the hot combustion gas. Therefore the reflector 600
also radiates
heat toward to the food.
[35] Meanwhile, combustion gas generated as a result of combustion of gas at
the upper
burner 500 is guided to the space between the ceiling of the oven chamber 211
and the
reflector 600 through the reflector 600. In more detail, the combustion gas is
collected
at the space formed by the second connection part 615 and two oblique parts
613
connected to the second connection part 615. Then, the collected combustion
gas flows
upward, that is, to the space between the ceiling of the oven chamber 211 and
the re-
flection part 610 through the exhaust hole 620.
[36] Therefore, when flames and heat generated by the upper burner 500 are
reflected by
the reflection part 610 toward food placed in the oven chamber 211, incomplete
combustion of gas at the upper burner 500 can be prevented, which may caused
by
combustion gas generated by combustion of the gas. Therefore, food placed in
the
oven chamber 211 can be cooked more efficiently by the upper burner 500, and
in-
complete combustion at the upper burner 500, which may result in harmful gases
such
as carbon monoxide, can be prevented.
Mode for the Invention
[37] Hereinafter, another reflector and a gas oven range including such
reflector will be
explained in detail with reference to the accompanying drawings according to a
second
embodiment.
[38] Fig. 4 is an exploded perspective view illustrating the upper burner 500
and a
reflector 700 of a gas oven range according to a second embodiment.
[39] Referring to Fig. 4, in the current embodiment, the reflector 700
includes a reflection
part 710, exhaust holes 730, fixing flanges 740, and cover parts 750. The
reflection
part 710 includes a plurality of first connection parts 711, oblique parts
713, and
second connection parts 715.
[40] That is, in the current embodiment, the reflector 700 further includes
cover parts 750
as compared with the previous embodiment. The cover parts 750 are provided so
that
flames and heat generated by combustion of gas at the upper burner 500 can be
prevented from flowing through the exhaust holes 730 to a space between the
top
CA 02732369 2011-01-27
6
WO 2010/013930 PCT/KR2009/004200
surface of the reflector 700 and the ceiling of the oven chamber 211 (refer to
Fig. 1).
Furthermore, owing to the cover parts 750, combustion gas generated by
combustion
of gas at the upper burner 500 can be uniformly distributed through the space
between
the top surface of the reflector 700 and the ceiling of the oven chamber 211.
[411 For this end, the cover parts 750 have a plate shape with a size
corresponding to the
size of the exhaust holes 730. The cover parts 750 are disposed directly above
the
exhaust holes 730. Owing to this structure, flames and heat generated by
combustion
of gas at the upper burner 500 are not transferred through the exhaust holes
730 to the
space between the top surface of the reflector 700 and the ceiling of the oven
chamber
211 but are reflected by the cover parts 750 downwardly toward the inside of
the oven
chamber 211. In addition, combustion gas discharged through the exhaust holes
730
can be uniformly distributed forward, backward, leftward, and/or rightward by
the
cover parts 750.
[421 Fixing ribs 751 are provided at front and rear end portions of each cover
part 750.
The fixing ribs 751 are provided to fix the cover part 750 to the reflection
part 710. In
the current embodiment, the fixing ribs 751 have an approximate L-shape and
disposed
at the front and rear end portions of each cover part 750. For example, the
fixing ribs
751 and the cover part 750 may be formed in one piece. Furthermore, the cover
part
750 and the reflector 700 may be formed in one piece. In this case, the
exhaust hole
730 and the cover part 750 may be formed by forming two parallel lines in the
second
connection part 715 by cutting the second connection part 715 in the length
direction
of the second connection part 715, and upwardly bending a portion of the
second
connection part 715 disposed between the parallel lines.
[431 Hereinafter, another reflector and a gas oven range including the
reflector will be
explained in detail with reference to the accompanying drawings according to a
third
embodiment.
[441 Fig. 5 is an exploded perspective view illustrating the upper burner 500
and the
reflector 800 of the gas oven range according to a third embodiment, and Fig.
6 is a
vertical sectional view illustrating reflection of flames and exhaustion of
combustion
gas at the reflector 800 according to the third embodiment.
[451 Referring to Figs. 5 and 6, in the current embodiment, the reflector 800
includes a re-
flection part 810, compartment parts 820, exhaust holes 830, and fixing
flanges 840.
The reflection part 810 includes a plurality of first connection parts 811,
oblique parts
813, and second connection parts 815.
[461 That is, in the current embodiment, the reflector 800 further includes
the com-
partment parts 820 as compared with the first and second embodiments. The com-
partment parts 820 are disposed between lateral surfaces of the oven chamber
211 and
lateral end portions of the reflector 800 for more complete compartment. In
other
CA 02732369 2011-01-27
7
WO 2010/013930 PCT/KR2009/004200
words, substantially, the oven chamber 211 is divided into a combustion space
215 and
an exhaust space 213 by the reflector 800. For this end, the compartment parts
820 are
provided on both sides of the reflector 800, that is, outer end portions of
the oblique
parts 813 of the reflection part 810. In more detail, the compartment parts
820 extend
outward from the outer end portions of the oblique parts 813 toward the
lateral surfaces
of the oven chamber 211. Outer end portions of the compartment parts 820 are
placed
close to the lateral surfaces of the oven chamber 211, respectively. The
distance
between the outer end portions of the compartment parts 820 and the lateral
surfaces of
the oven chamber 211 may be at least smaller than the width of the exhaust
holes 830.
Therefore, the combustion space 215 is formed by the lateral, rear, and bottom
surfaces
of the oven chamber 211 and the bottom surfaces of the reflector 800, and the
exhaust
space 213 is formed by the lateral, rear, and ceiling surfaces of the oven
chamber 211
and the top surface of the reflector 800.
[47] The exhaust holes 830 are formed in the reflection part 810,
specifically, in the
second connection parts and the compartment parts 820. Combustion gas
generated as
a result of combustion of gas at the upper burner 500 is colleted between the
upper
burner 500 and the reflector 800, that is, at a space formed by the second
connection
part 815 and two oblique parts 813 connected to the second connection part
815, and
then the combustion gas is discharged to the exhaust space 213 through the
exhaust
hole 830. For this end, the exhaust holes 620 are formed into an elongated
shape by
partially cutting out the second connection parts 815 and the compartment
parts 820 of
the reflection part 810 in a longitudinal direction thereof, i.e. in the
prefered em-
bodiment in a front-to-back direction.
[48] In the current embodiment, the reflection part 810 and the fixing flanges
840 of the
reflector 800 have the same structures as those explained in the first and
second em-
bodiments. Thus, descriptions thereof will be omitted.
[49] Hereinafter, another reflector and a gas oven range including the
reflector will be
explained in detail with reference to the accompanying drawings according to a
third
embodiment.
[50] Fig. 7 is a perspective view illustrating the upper burner 500 and the
reflector 900 of
the gas oven range according to a fourth second embodiment.
[51] Referring to Fig. 7, in the current embodiment, the reflector 900
includes a reflection
part 910, compartment parts 920, exhaust holes 930, fixing flanges 940, and
cover
parts 950. The reflection part 910 includes a plurality of first connection
parts 911,
oblique parts 913, and second connection parts 915.
[52] That is, in the current embodiment, the reflector 900 further includes
the cover parts
950 as compared with the third embodiment. The cover parts 950 are provided so
that
flames and heat, in particular radiant heat generated by combustion of gas at
the upper
CA 02732369 2011-01-27
8
WO 2010/013930 PCT/KR2009/004200
burner 500 can be prevented from flowing from a lower side of the reflector
900 (that
is, the combustion space 215) to a space (the exhaust space 213) formed
between the
top surface of the reflector 900 and the ceiling of the oven chamber 211
(refer to Fig.
3). Furthermore, owing to the cover parts 950, combustion gas generated by
combustion of gas at the upper burner 500 can be uniformly distributed
throughout the
exhaust space 213.
[53] For this end, the cover parts 950 have a plate shape with a size
corresponding to the
size of the exhaust holes 930. The cover parts 950 are disposed directly above
the
exhaust holes 930. Owing to this structure, flames and heat generated by
combustion
of gas at the upper burner 500 are not transferred through the exhaust holes
930 to the
upper side of the reflector 900 (that is, the exhaust space 213) but are
reflected by the
reflector 900 toward the lower side of the reflector 900 (that is, the
combustion space
215). In addition, combustion gas discharged through the exhaust holes 930 can
be
uniformly distributed by the cover parts 950 forward, backward, leftward,
and/or
rightward inside the exhaust space 213.
[54] In the current embodiment, the reflection part 910 and the fixing flanges
940 of the
reflector 900 have the same structures as those explained in the first and
second em-
bodiments. Thus, descriptions thereof will be omitted.
[55] Although embodiments have been described with reference to a number of il-
lustrative embodiments thereof, it should be understood that numerous other
modi-
fications and embodiments can be devised by those skilled in the art that will
fall
within the scope of the present invention.
Industrial Applicability
[56] According to the embodiments, incomplete combustion of gas at the burner
can be
prevented, and food can be efficiently cooked by heat generated by combustion
of gas
at the burner.
[57] As described above, the reflector and the gas oven range including the
reflector can
provide the following effects.
[58] According to the embodiments of the present disclosure, combustion gas
generated
by combustion of gas at the upper burner is discharged to the space between
the top
surface of the reflector and the ceiling of the oven chamber through the
exhaust holes
of the reflector. Therefore, incomplete combustion at the upper burner can be
prevented, and thus efficiency decrease and generation of harmful gases can be
prevented.
[59] In addition, according to the present disclosure, flames and heat
generated by
combustion of gas at the upper burner are not transferred to the space between
the top
surface of the reflector and the ceiling of the oven chamber through the
exhaust holes
CA 02732369 2011-01-27

WO 2010/013930 PCT/KR2009/004200
of the reflector. Therefore, food can be cooked in the oven chamber more
efficiently.
