FIG. 3 is a bottom view illustrating the oven burner 500.FIG. 4 is a side view illustratingflame holes 541 of the oven burner 500. - Referring to
FIGS. 2 to 4 , the oven burner 500 includes asupply part 510 supplying a gaseous fuel mixed with air, and acombustion part 520 having an end connected to thesupply part 510 to burn the mixed gaseous fuel supplied from thesupply part 510. - The
supply part 510 provides thecombustion part 520 with a gaseous fuel supplied from a nozzle (not shown), and air supplied together with the gaseous fuel. Thesupply part 510 may pass through a sidewall of thecavity 210, or the nozzle may pass through the sidewall of thecavity 210. Thesupply part 510 is aligned with the nozzle in the state where thesupply part 510 is spaced apart from the nozzle. - The
combustion part 520 is horizontally disposed within thecavity 210. Thecombustion part 520 includes first through fourthstraight portions third connection portions straight portions - The first through fourth
straight portions - The
supply part 510 is connected to the firststraight portion 521. Thesupply part 510 may extend along the firststraight portion 521 or be tilted from the firststraight portion 521. In the present embodiment, thesupply part 510 is disposed along the firststraight portion 521. - The
first connection portion 531 connects a first end of the firststraight portion 521 to a first end of the secondstraight portion 522. Thesecond connection portion 532 connects a first end of the thirdstraight portion 523 to a second end of the secondstraight portion 522. Thethird connection portion 533 connects a second end of the thirdstraight portion 523 to the fourthstraight portion 524. - Thus, the
combustion part 520 is bent at a plurality of times in a zigzag shape or S-shape as a whole. The fourthstraight portion 524, at which a mixed gaseous fuel finally arrives, has a closed end. - That is, the
combustion part 520 has an open curve shape that is opposite to a loop shape (closed curve shape) in the present embodiment. - Although the
combustion part 520 includes the first through fourthstraight portions third connection portions combustion part 520 may include two straight portions and a single connection portion. Alternatively, thecombustion part 520 may include a single straight portion and a single connection portion. - The first through

straight portions flame holes - Along the flow path of a mixed gaseous fuel, the first
straight portion 521 is closer to thecombustion part 520 than the fourthstraight portion 524. Thus, flames generated from the first through forth flame holes 541, 542, 543, and 544 may decrease from the firststraight portion 521 toward the fourthstraight portion 524. - Thus, the fourth flame holes 544 are greater than the third flame holes 543, and the third flame holes 543 are greater than the second flame holes 542, and the second flame holes 542 are greater than the first flame holes 541, so as to uniformly generate flames at the first through fourth
straight portions - Alternatively, the first and second flame holes 541 and 542 may be the same in size, and the third and fourth flame holes 543 and 544 may be the same in size, and the third flame holes 543 may be greater than the second flame holes 542.
- That is, according to the present embodiment, distant one of the flame holes 541 through 544 along the flow path of a mixed gaseous fuel from the
supply part 510 may be greater than close one thereof to thesupply part 510. - Thus, even when the amount of a mixed gaseous fuel provided to the fourth
straight portion 524 is less than that of the firststraight portion 521, since the fourth flame holes 544 are greater than the first flame holes 541, flames at the first through fourth flame holes 541, 542, 543, and 544 are uniform. - The first through
third connection portions straight portions third connection portions third connection portions - Each of the first through
third connection portions outer connection portions inner connection portions 535. In this case, the number of the first through third flame holes 545, 546, and 547 is less than that when providing the first through third flame holes 545, 546, and 547 to theouter connection portions 536. - A distance between each group of the first through third flame holes 545, 546, and 547 is greater than a distance between each group of the first through fourth flame holes 541, 542, 543, and 544 to prevent interference between flames generated from the first through third flame holes 545, 546, and 547.
- According to the present embodiment, the
single combustion part 520 is bent at one or more times, flame areas are increased. Particularly, since thecombustion part 520 is bent in a zigzag shape, food can be uniformly heated. - Flames are uniformly generated at the first through fourth
straight portions supply part 510. - Although the
combustion part 520 includes the first through fourthstraight portions third connection portions combustion part 520 may be round as a whole. - Referring to
FIG. 4 , the oven burner 500 includes alower case 501 and anupper case 502, and the first flame holes 541 are exemplified. Hereinafter, the reference numerals of the second through fourth flame holes 542, 543, and 544 will be omitted. - For example, the
lower case 501 may be coupled to theupper case 502 through a screw. Alternatively, thelower case 501 may be coupled to theupper case 502 through a rivet. However, the coupling of thelower case 501 and theupper case 502 is not limited thereto. - At least one of the
lower case 501 and theupper case 502 is provided with a plurality of flamehole forming regions 505 for forming the flame holes 541. In the present embodiment, thelower case 501 is provided with the flamehole forming regions 505. - The flame
hole forming regions 505 are formed by partially processing thelower case 501. Adjacent two of the flamehole forming regions 505 are connected through aconnection region 504. - When the
lower case 501 is coupled to theupper case 502, agap 508 for transferring a flame is disposed between at least adjacent two of the flame holes. That is, thelower case 501 is spaced apart from theupper case 502 except for a region where theupper case 502 is coupled to thelower case 501. To space thelower case 501 apart from theupper case 502, agap forming region 503 may be provided to theupper case 502. When theupper case 502 is provided with the flamehole forming regions 505, thegap forming region 503 may be provided to thelower case 501. - That is, when the
lower case 501 is coupled to theupper case 502, theconnection region 504 is spaced apart from thegap forming region 503 that faces theconnection region 504. - The vertical distance of the
gap 508 is less than those of the flame holes 541. - According to the present embodiment, the
gap 508 efficiently transfers a flame between at least adjacent two of the flame holes. - Particularly, even when the oven burner 500 is in a low operation mode (where flames are weak), flames can be efficiently transferred between the flame holes.
- Since a flame is efficiently transferred between the flame holes, flame intensities (flame hole load) of the flame holes are substantially uniform, so as to uniformly heat food.
- The
reflector 600 may be disposed between aceiling 212 of thecavity 210 and the oven burner 500. - When a gaseous fuel is burned at the oven burner 500, the
reflector 600 reflects flames and heat downwardly toward food placed in thecooking chamber 211. In addition, combustion gas generated while burning a gaseous fluid at the oven burner 500 is introduced upwardly between theceiling 212 of thecooking chamber 211 and the top of thereflector 600 by thereflector 600. - Referring again to
FIGS. 1 and 2 , thereflector 600 includes areflection part 610,exhaust parts 620, coverparts 640, and fixingflanges 630.

flanges 630 are disposed on corners of the top surface of thereflection part 610. The fixingflanges 630 are used to fix thereflection part 610 to theceiling 212 of thecooking chamber 211. The fixingflanges 630 may be formed at the corners of thereflection part 610 by partially cutting and upwardly bending the first connection surfaces 611 and the oblique surfaces 613. - When a gaseous fuel is burned at the oven burner 500, combustion gas is collected between the oven burner 500 and the
reflection part 610, that is, in spaces formed by the second connection surfaces 615 and theoblique surfaces 613 connected to the second connection surfaces 615. Then, the combustion gas is discharged to a space between theceiling 212 of thecooking chamber 211 and thereflection part 610 through theexhaust parts 620. For this end, theexhaust parts 620 are formed into an elongated shape by partially cutting out the second connection surfaces 615 in a front-to-back direction. - Furthermore, owing to the
cover parts 640, combustion gas generated by combustion of gas at the oven burner 500 can be uniformly distributed through the space between the top surface of thereflector 600 and theceiling 212 of thecooking chamber 211. - For this end, the
cover parts 640 have a plate shape with a size corresponding to the size of theexhaust parts 620. Thecover parts 640 are disposed directly above theexhaust parts 620. Owing to this structure, flames and heat generated by combustion of gas at the oven burner 500 are not transferred through theexhaust parts 620 to the space between the top surface of thereflector 600 and theceiling 212 of thecooking chamber 211 but are reflected by thecover parts 640 downwardly toward the inside of thecooking chamber 211. In addition, combustion gas discharged through theexhaust parts 620 can be uniformly distributed forward, backward, leftward, and/or rightward by thecover parts 640. - Fixing ribs are provided at front and rear end portions of each
cover part 640. The fixing ribs are provided to fix thecover part 640 to thereflection part 610. In the present embodiment, the fixing ribs have an approximate L-shape and disposed at the front and rear end portions of eachcover part 640. For example, the fixing ribs and thecover part 640 may be formed in one piece. Furthermore, thecover part 640 and thereflector 600 may be formed in one piece. In this case, theexhaust part 620 and thecover part 640 may be formed by forming two parallel lines in thesecond connection surface 615 in the length direction of thesecond connection surface 615, by cutting thesecond connection surface 615 along the parallel lines, and by upwardly bending a portion of thesecond connection surface 615 disposed between the parallel lines. - Hereinafter, operation of the
cooking device 1 will now be described. - A user can input a manipulation signal by using the
control part 400 for cooking food using theoven part 200. If a manipulation signal is input through thecontrol part 400, the oven burner 500 is operated to cook food in thecooking chamber 211. - In detail, gas and air are supplied to the oven burner 500, and flames are generated by combustion of the gas and air. Then, food is cooked in the
cooking chamber 211 by flames and heat generated at the oven burner 500. At this time, thereflector 600 reflects flames and heat generated by combustion of gas at the oven burner 500, toward the food placed in thecooking chamber 211. - Meanwhile, combustion gas generated as a result of combustion of gas at the oven burner 500 is guided to the space between the
ceiling 212 of thecooking chamber 211 and thereflector 600 through thereflector 600. In more detail, the combustion gas is collected at the space formed by thesecond connection surface 615 and twooblique surfaces 613 connected to thesecond connection surface 615. Then, the collected combustion gas flows upward, that is, to the space between theceiling 212 of thecooking chamber 211 and thereflection part 610 through theexhaust part 620. -
