DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] 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 embodiment.
[0019] FIG. 1 is a perspective view illustrating a gas oven range 1
according to a first embodiment, and FIG. 2 is an exploded
perspective view illustrating an upper burner 500 and a reflector
600 according to the first embodiment.
[0020] 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 main body 10 at a rear edge portion
corresponding to a rear side of the cook top part 100.
[0021] 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.
[0022] 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).
[0023] 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.
[0024] A container in which food is contained can be stored in the
drawer part 300 at a predetermined temperature. The drawer part 300
includes a drawer 310 in which a container can be placed.
[0025] 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
information about operational conditions of the oven range 1.
[0026] 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 embodiment,
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.
[0027] 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.
[0028] 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.
[0029] 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 510. 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.
[0030] 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
reflection part 610 by cutting and upwardly bending the first
connection parts 611 and the oblique parts 613.
[0031] 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 preferred embodiment is
a front-to-back direction.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] 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
reflection part 610 through the exhaust hole 620.
[0037] 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 incomplete combustion at the upper burner 500,
which may result in harmful gases such as carbon monoxide, can be
prevented.
[0038] 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.
[0039] 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.
[0040] 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.
[0041] 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 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.
[0042] 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.
[0043] 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.
[0044] 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.
[0045] 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.
[0046] Referring to FIGS. 5 and 6, in the current embodiment, the
reflector 800 includes a reflection 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.
[0047] That is, in the current embodiment, the reflector 800
further includes the compartment parts 820 as compared with the
first and second embodiments. The compartment 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 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.
[0048] 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 collected 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 preferred embodiment in
a front-to-back direction.
[0049] 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 embodiments. Thus,
descriptions thereof will be omitted.
[0050] 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.
[0051] 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.
[0052] 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.
[0053] 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 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.
[0054] 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.
[0055] 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 embodiments. Thus,
descriptions thereof will be omitted.
[0056] 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.
[0057] As described above, the reflector and the gas oven range
including the reflector can provide the following effects.
[0058] 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.
[0059] 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 of
the reflector. Therefore, food can be cooked in the oven chamber
more efficiently.
[0060] Although embodiments have been described with reference to a
number of illustrative embodiments thereof, it should be understood
that numerous other modifications and embodiments can be devised by
those skilled in the art that will fall within the scope of the
present invention.
