Abstract

A cooking device is provided. The cooking device includes a frame that forms a cooking chamber; a burner provided inside the frame and having a plurality of gas outlet holes; an ignition unit provided inside the frame to ignite a mixed gas discharged from at least one of the plurality of gas outlet holes; and a fixing device to affix a position of the ignition unit with respect to the burner.

First claim

What is claimed is:

1. A cooking device comprising:
a frame that forms a cooking chamber;
a burner provided in the frame and having a plurality of gas outlet holes;
an ignition unit provided in the frame and including an ignition bar to ignite a mixed gas discharged from at least one of the plurality of gas outlet holes; and
a fixing device to affix a position of the ignition unit with respect to the burner,
wherein the burner comprises:
a burner tube having a first end, a second end spaced apart from the first end, and a body portion connected to the first and second ends and rounded in a convex shape, and
a supply part extended from the first end of the burner tube,
wherein an inner circumferential surface of the burner tube includes the plurality of gas outlet holes, and
wherein the ignition bar is positioned between the first end and the second end to face at least one of the plurality of gas outlet holes.

2. The cooking device of claim 1 , wherein the fixing device affixes the ignition unit to the burner.

3. The cooking device of claim 2 , wherein the fixing device comprises a first bracket that is attached to the burner, and a second bracket that is attached to the ignition unit.

4. The cooking device of claim 2 , wherein the second bracket is separably attachable to the first bracket.

5. The cooking device of claim 4 , wherein one of the first bracket and the second bracket comprises a first hook, and the other one thereof comprises a hook coupling hole to which the first hook is attached, and when the first hook is attached to the hook coupling hole, the first and second brackets are fastened together by a first fastening member.

6. The cooking device of claim 5 , wherein the first fastening member fastens the first bracket and the second bracket in a forward and backward direction with respect to the cooking chamber.

7. The cooking device of claim 5 , wherein one of the second bracket and the ignition unit comprises a second hook, and the other one thereof comprises a hook through-hole in which the second hook passes, and when the second hook passes in the hook through-hole, the second bracket and the ignition unit are fastened together by a second fastening member.

8. The cooking device of claim 7 , wherein the first fastening member is positioned at a different height than the second fastening member.

9. The cooking device of claim 5 , wherein the second bracket further comprises a fastening rib, and the first bracket further comprises a rib insertion hole in which the fastening rib is inserted.

10. The cooking device according to claim 9 , wherein, when the fastening rib is inserted in the rib insertion hole, the first bracket and the second bracket are fastened together by the first fastening member.

11. The cooking device of claim 1 , wherein the body portion is extended downward to form the convex shape.

12. The cooking device of claim 1 , further comprising a burner cover which receives the burner tube, wherein at least a portion of the ignition unit is provided within the burner cover.

13. The cooking device of claim 12 , wherein the burner cover comprises an opening through which air passes, and the ignition bar is provided at an area between the opening of the burner cover and the burner tube.

14. The cooking device of claim 1 , further comprising a burner cover which covers the burner, wherein at least a portion of the ignition unit is provided within the burner cover, and
wherein the fixing device affixes the ignition unit to the burner cover.

15. The cooking device of claim 14 , wherein the burner cover comprises a burner through-portion through which the burner passes and is in contact with the frame, and at least a portion of the fixing device is provided within an area formed by the burner through-portion.

16. A cooking device comprising:
a frame that forms a cooking chamber;
a burner cover provided in the frame to form a combustion chamber that is partitioned from the cooking chamber, the burner cover having an opening to define an air path;
a burner provided in the burner cover and having a plurality of gas outlet holes;
an ignition unit provided in the burner cover at the combustion chamber and including an ignition bar to ignite a mixed gas discharged from at least one of the plurality of gas outlet holes; and
a fixing device to support the ignition unit in the burner cover,
wherein the ignition bar is positioned between the opening of the burner cover and the burner.

17. The cooking device of claim 16 , wherein the fixing device comprises a first bracket that is attached to the burner or the burner cover, and a second bracket that is attached to the ignition unit, wherein the second bracket is separably attachable to the first bracket.

18. The cooking device of claim 16 , wherein one of the first bracket and the second bracket comprises a hook, and the other one thereof comprises a hook coupling hole to which the hook is attached, and when the hook is attached to the hook coupling hole, the first bracket and second brackets are fastened together by a fastening member.

19. The cooking device of claim 18 , wherein the fastening member fastens the first and second brackets together in a direction which is parallel with a flowing direction of air passing through the opening.
