Abstract

A cooking device includes a frame to form a cooking chamber; a burner disposed in the cooking chamber and to generate a flame for supplying heat to the cooking chamber; a burner cover in which the burner is installed and having a plate with an outlet opening through which an air passes; a fan to flow an air of the cooking chamber; and a stabilizer to reduce an influence of the air on a flame of the burner when the air of the cooking chamber passes through the outlet opening of the burner cover by the fan. The stabilizer includes: a body having an opening for air passage; a barrier extended from the body; and a fastening unit for fastening the body to the burner cover, and while the fastening unit is fastened to the burner cover, the body is spaced apart from the plate of the burner cover.

First claim

What is claimed is:

1. A cooking device comprising:
a frame that forms a cooking chamber;
a burner disposed in the cooking chamber;
a burner cover that covers the burner, the burner cover including a plate formed with an outlet opening through which air passes;
a fan that moves the air inside the cooking chamber; and
a stabilizer that reduces an influence of the air on a flame of the burner,

wherein the stabilizer comprises:
a stabilizer body having an opening;
a stabilizer barrier that extends from the stabilizer body; and
a stabilizer fastener that attaches the stabilizer body to the burner cover,
wherein the stabilizer comprises at least one stabilizer hook that fastens to the burner cover, and
wherein the burner cover comprises at least one hook coupling hole that is configured to receive the at least one stabilizer hook.

2. The cooking device of claim 1 , wherein the stabilizer fastener protrudes toward the plate from the stabilizer body.

3. The cooking device of claim 1 , wherein the stabilizer fastener and the plate of the burner cover each comprise a fastening hole that is configured to fasten with a fastening member.

4. The cooking device of claim 3 , wherein the stabilizer comprises at least one fastening hole.

5. The cooking device of claim 4 , wherein, the at least one stabilizer hook is aligned with the at least one hook coupling hole, and the fastening hole of the stabilizer is not in alignment with the fastening hole of the burner cover.

6. The cooking device of claim 5 , wherein, when the stabilizer is rotated in a first direction while the at least one stabilizer hook penetrates the at least one hook coupling hole, the fastening hole of the stabilizer is in alignment with the fastening hole of the burner cover.

7. The cooking device of claim 4 , wherein the burner cover further comprises an erroneous assembly preventing unit that restricts rotation of the stabilizer when the at least one stabilizer hook does not penetrate the at least one hook coupling hole.

8. The cooking device of claim 7 , wherein the erroneous assembly preventing unit protrudes in a direction toward the stabilizer.

9. The cooking device of claim 4 , wherein the stabilizer comprises a plurality of stabilizer hooks, whereby a distance between the stabilizer hooks and a first group of two adjacent hooks is different than a distance between the stabilizer hooks and a second group of two adjacent hooks.

10. The cooking device of claim 3 , wherein the burner cover further comprises a fastening boss that extends toward the frame.

11. The cooking device of claim 1 , wherein the fan is provided between the burner cover and the frame, and the stabilizer further comprises a forming unit that is formed in a direction away from the fan to increase a gap between the stabilizer body and the fan.

12. The cooking device of claim 11 , wherein the forming unit further comprises an opening through which the air passes, and a diameter of the opening of the forming unit is less than an outer diameter of the fan.

13. The cooking device of claim 1 , wherein the burner further comprises a gas outlet hole, and the stabilizer barrier extends toward the gas outlet hole from the stabilizer body.

14. A cooking device comprising:
a frame that forms a cooking chamber;
a burner provided in the cooking chamber;
a burner cover that forms a combustion chamber in which the burner is located, and having an outlet opening through which air passes and a hook coupling hole;
a fan that moves the air inside the cooking chamber; and
a stabilizer fastened to the burner cover in the combustion chamber,
wherein the stabilizer includes:
a stabilizer body with an opening for air passage;
a stabilizer barrier extended from the body;
a stabilizer fastener that fastens the stabilizer body to the burner cover; and
a stabilizer hook configured to be inserted in the hook coupling hole to fasten the stabilizer body to the burner cover, and
wherein the burner cover further comprises an erroneous assembly preventing unit that restricts rotation of the stabilizer when the stabilizer hook does not penetrate the hook coupling hole.

15. The cooking device of claim 14 , wherein, when the stabilizer is rotated in a first direction while the stabilizer hook penetrates the hook coupling hole, the fastening hole of the stabilizer is in alignment with the fastening hole of the burner cover.

16. The cooking device of claim 14 , wherein the erroneous assembly preventing unit protrudes in a direction toward the stabilizer.

17. The cooking device of claim 14 , wherein the stabilizer includes a plurality of stabilizer hooks and the burner cover includes a plurality of hook penetration holes, whereby a distance between the stabilizer hooks and a first group of two adjacent hooks is different than a distance between the stabilizer hooks and a second group of two adjacent hooks.
