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 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.
[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.
[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 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 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 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 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 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 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 of the reflector. Therefore, food can be cooked in the oven chamber more efficiently.
[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).

[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.
[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.

[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.
[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 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 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 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 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 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 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 of the reflector. Therefore, food can be cooked in the oven chamber more efficiently.
