Abstract

A cooking device including a frame that defines a cooking chamber, a burner cover provided in the frame to form a combustion chamber and includes an opening for flowing air, a burner provided inside the combustion chamber, and a barrier member provided between the burner cover and the frame in order to prevent heat of air discharged from the combustion chamber from being delivered to the frame.

First claim

What is claimed is:

1. A cooking device comprising:
a frame to form a cooking chamber;
a burner cover provided in the frame to form a combustion chamber, with the burner cover having an opening for air to flow;
a burner provided inside the combustion chamber; and
a barrier member provided between the burner cover and a rear wall of the frame to form an exhaust flow path for heated air in order to prevent heat of air discharged from the combustion chamber from being delivered to the rear wall of the frame,
wherein the burner cover covers a front of the burner and a rear of the burner,
wherein air heated by the burner in the combustion chamber passes through the exhaust flow path between the burner cover and the barrier member,
wherein the barrier member is affixed to the frame,
wherein the barrier member comprises:
a barrier plate in contact with the frame; and
a cover fastener that is fastened to the burner cover,
wherein the burner cover is spaced apart from the barrier plate, when the burner cover is fastened to the cover fastener.

2. The cooking device of claim 1 , further comprising:
a fan motor provided outside the frame; and
a fan connected to a shaft of the fan motor within the frame,
wherein the barrier member comprises a shaft through-hole through which the shaft of the fan motor passes.

3. The cooking device of claim 2 , wherein:
the fan is provided between the frame and the burner cover, and
the diameter of the shaft through-hole is greater than the diameter of the fan.

4. The cooking device of claim 2 , wherein:
the barrier member includes a vertical part that is parallel to a vertical line and an inclination part that is inclined from the vertical line, and
the shaft through-hole is provided in the inclination part.

5. The cooking device of claim 4 , wherein:
an exhaust flow path, through which air flows from the combustion chamber to the cooking chamber, is provided between the burner cover and the barrier member, and
the width of the exhaust flow path at the inclination part is greater than the width of the exhaust flow path at the vertical part.

6. The cooking device of claim 5 , wherein the width of the exhaust flow path is reduced from a part adjacent to the shaft through-hole of the inclination part to the vertical part.

7. The cooking device of claim 1 , wherein the cover fastener extends from the barrier plate.

8. The cooking device of claim 7 , wherein the cover fastener comprises:
an extension extending from the barrier plate towards the burner cover; and
a fastening body bent from the extension and having a fastening hole formed therein for fastening with a fastening member.

9. The cooking device of claim 8 , wherein the burner cover comprises a first cover and a second cover,
wherein the fastening member passes through the first cover and the second cover and is fastened to the fastening hole.

10. The cooking device of claim 8 , wherein the fastening body extends in a vertical direction.

11. The cooking device of claim 10 , wherein the extension comprises a strength reinforcement unit for strength reinforcement, whereby the strength reinforcement unit has a groove or protrusion shape.

12. The cooking device of claim 7 , wherein a strength reinforcement unit for strength reinforcement is formed on a part of the barrier plate where the burner fastener is located.

13. The cooking device of claim 9 , wherein the fastening hole comprises a first fastening hole and a second fastening hole,
the first cover includes a first cover combination part formed in the first fastening hole, and
the second cover includes a second cover combination part formed in the second fastening hole,
whereby the fastening member is fastened to the first cover combination part and the second cover combination part after passing through the first fastening hole and the second fastening hole.

14. The cooking device of claim 1 , wherein the burner cover comprises a first cover and a second cover,
wherein the opening comprises a first opening provided in the first cover and a second opening provided in the second cover.

15. The cooking device of claim 1 , wherein a burner through-hole, through which the burner passes, is provided in the barrier member.

16. The cooking device of claim 15 , further comprising an ignition unit to ignite a mixed gas,
wherein a flange is provided on the barrier member near the burner through-hole, the flange configured to prevent a wire connected to the ignition unit from being damaged.

17. The cooking device of claim 1 , wherein the burner cover comprises a first cover including a first cover combination part and a second cover including a second cover combination part,
wherein the cover fastener is fastened to the first cover combination part and/or the second cover combination part.

18. A cooking device comprising:
a frame to form a cooking chamber;
a barrier member fastened to the frame;
a burner cover fastened to the barrier member within the frame and spaced apart from the frame, the burner cover forming a combustion chamber;
a burner provided inside the combustion chamber;
a fan motor provided outside the frame; and
a fan connected to a shaft of the fan motor passing through the frame and the barrier member, provided between the burner cover and the frame,
wherein the barrier member comprises:
a barrier plate in contact with the frame; and
a cover fastener extending from the barrier plate to fasten with the burner cover,
wherein the burner cover is spaced apart from the barrier plate, when the burner cover is fastened to the cover fastener,
wherein the barrier member is provided between the burner cover and a rear wall of the frame to form an exhaust flow path for heated air, the barrier member configured to prevent heat of air discharged from the combustion chamber from being delivered to the rear wall of the frame,
wherein the burner cover covers a front of the burner and a rear of the burner, and
wherein air heated by the burner in the combustion chamber passes through the exhaust flow path between the burner cover and the barrier member.

19. The cooking device of claim 18 , wherein:
the barrier member includes a shaft through-hole through which the shaft of the fan motor passes, and
the diameter of the shaft through-hole is greater than the diameter of the fan.

20. The cooking device of claim 18 , wherein:
the burner cover comprises a first cover and a second cover,
the first cover and the second cover each includes an opening formed therein through which air heated by the burner passes, and
a horizontal distance between the shaft through-hole and the opening of the second cover is less than a horizontal length of the cover fastener.

21. The cooking device of claim 18 , wherein the cover fastener comprises:
an extension extending from the barrier plate towards the burner cover; and
a fastening body bent from the extension and having a fastening hole formed therein for fastening with a fastening member,
wherein the fastening member passes through the burner cover and is fastened to the fasting hole.

22. The cooking device of claim 21 , wherein:
the burner cover comprises a first cover and a second cover,
the fastening hole comprises a first fastening hole and a second fastening hole,
the first cover includes a first cover combination part formed in the first fastening hole, and
