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 to ignite a mixed gas discharged from at least one of the plurality of gas outlet holes;
a fixing device to affix a position of the ignition unit with respect to the burner; and
a burner cover to which the ignition unit is fixed,
wherein the burner cover comprises a burner through-portion through which the burner passes and is in contact with the frame, and a portion of the ignition unit is provided within an area formed by the burner through-portion.

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 ignition unit comprises an ignition bar that faces at least one of the plurality of gas outlet holes of the burner.

12. The cooking device of claim 11 , wherein the burner comprises a burner tube of which opposite ends of the burner tube are spaced apart from each other, and the burner tube comprises an inner circumferential surface and an outer circumferential surface, and the plurality of gas outlet holes are provided at the inner circumferential surface.

13. The cooking device of claim 11 , 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. 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;
a burner provided at the combustion chamber and having a plurality of gas outlet holes;
an ignition unit provided at the combustion chamber 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;
wherein the burner cover comprises a burner through-portion through which the burner passes and is in contact with the frame, and a portion of the ignition unit is provided within an area formed by the burner through-portion.

15. The cooking device of claim 14 , 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.

16. The cooking device of claim 14 , 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.

17. The cooking device of claim 14 , wherein the burner cover comprises an opening through which air passes, and 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.
