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;
a burner provided inside the combustion chamber;
the burner cover comprising a first cover covering a front of the burner and a second cover such that at least a portion of the second cover covers a rear of the burner,
wherein the first cover includes a first opening through which air from within the cooking chamber passes and the second cover includes a second opening through which air heated by the burner in the combustion chamber exits the burner cover; and
a barrier member provided between the burner cover and a rear wall of the frame to form an exhaust flow path for the heated air to prevent damage to the rear wall of the frame by the heat of air discharged from the combustion chamber,
wherein air heated by the burner in the combustion chamber passes through the second hole, passes through the exhaust flow path between the burner cover and the barrier member, and is discharged to the cooking chamber.

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

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 larger than the diameter of the fan.

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

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

6. The cooking device of claim 5 , wherein the width of the exhaust flow path decreases 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 barrier member is attached to the frame.

8. The cooking device of claim 7 , wherein the barrier member includes:
a barrier plate that contacts the frame; and
a cover fastener extending from the barrier plate, whereby the cover fastener is configured to fasten with the burner cover.

9. The cooking device of claim 8 , wherein the cover fastener includes:
an extension portion that extends from the barrier plate; and
a fastening body that is bent from an end of the extension portion, whereby the fastening body is configured to fasten with the burner cover.

10. The cooking device of claim 9 , wherein the extension portion includes a strength reinforcement unit.

11. The cooking device of claim 8 , wherein a strength reinforcement unit for strength reinforcement is formed on a portion of the barrier plate where the burner fastener is located.

12. The cooking device of claim 8 , wherein:
the fastening body includes a fastening hole that is configured to fasten with a fastening member, and
the burner cover includes a first cover and a second cover,
whereby the fastening member passes through the first and second covers and is fastened with the fasting hole.

13. The cooking device of claim 12 , wherein the opening of the burner cover includes a first opening provided in the first cover and a second opening provided in the second cover.

14. The cooking device of claim 1 , wherein the barrier member further includes a burner through-hole through which the burner passes.

15. The cooking device of claim 14 , further comprising:
an ignition unit to ignite a mixed gas, the ignition unit having a wire connected thereto, and
a flange formed in the barrier plate, the flange configured to prevent damage to the wire.

16. A cooking device, comprising:
a frame to form a cooking chamber;
a burner cover provided in the frame to form a combustion chamber;
a burner provided inside the combustion chamber;
the burner cover comprising a first cover covering a front of the burner and a second cover such that at least a portion of the second cover covers a rear of the burner,
wherein the first cover includes a first opening through which air from within the cooking chamber passes and the second cover includes a second opening through which air heated by the burner in the combustion chamber exits the burner cover;

a barrier member attached to the frame to form an exhaust flow path for the heated air to prevent damage to the rear wall of the frame by the heat of air discharged from the combustion chamber;
a fan motor provided outside of the frame, the fan motor having a shaft connected thereto that passes through the frame and the barrier member;
a fan connected to the shaft of the fan motor, the fan being disposed between the burner cover and the frame; and
wherein the burner cover is attached to the barrier member within the frame and spaced apart from the frame such that air heated by the burner in the combustion chamber passes through the second hole, passes through the exhaust flow path between the burner cover and the barrier member, and is discharged to the cooking chamber.

17. The cooking device of claim 16 , wherein the barrier member comprises:
a barrier plate that contacts the frame; and
a cover fastener extending from the barrier plate, whereby the cover fastener is configured to fasten with the burner cover.

18. The cooking device of claim 17 , wherein:
the barrier member includes a shaft through-hole to receive the shaft of the fan motor, and
the diameter of the shaft through-hole is larger than the diameter of the fan.

19. The cooking device of claim 17 , wherein:
the burner cover includes an opening through which air heated by the burner passes, and
a horizontal distance between the shaft through-hole and the opening is less than a horizontal length of the cover fastener.

20. The cooking device of claim 17 , further comprising:
an extension portion that extends from the barrier plate; and
a fastening body that is bent from an end of the extension portion, whereby the fastening body is configured to fasten with the burner cover.
