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, 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 a first opening which air within the cooking chamber is flowing into the combustion chamber and a second opening for discharging air from the combustion chamber;
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 the heated air to prevent damage to the rear wall of the frame by the heat of air discharged from the combustion chamber,
wherein a part of the barrier member is fastened to the rear wall of the frame and spaced apart from the burner cover wherein air heated by the burner in the combustion chamber passes through the second hole, passed through the exhaust flow path between the burner cover and the barrier member, and is discharged to the cooking chamber;
wherein the barrier member includes a barrier plate having a vertical part parallel to a vertical line and an inclination part inclined from the vertical line, and a shaft through-hole is formed in the inclination part; and
wherein the exhaust flow path, along which air flows from the combustion chamber to the cooking chamber, is formed between the burner cover and the barrier member, and the width of the exhaust flow path at the inclination part is greater than that of the exhaust flow path at the vertical part.

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 shaft of the fan motor passes through the shaft through-hole.

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 that of the fan.

4. The cooking device of claim 1 , 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.

5. The cooking device of claim 1 , wherein the barrier plate is in contact with the frame; and a cover fastener extending from the barrier plate, for fastening with the burner cover.

6. The cooking device of claim 5 , wherein the cover fastener includes:
an extension extending from the barrier plate; and
a fastening body bent from the extension, for fastening with the burner cover.

7. The cooking device of claim 6 , wherein the extension includes a strength reinforcement unit for strength reinforcement and the strength reinforcement unit has a groove or protrusion shape.

8. The cooking device of claim 5 , wherein a strength reinforcement unit for strength reinforcement is formed on a part, in which the burner fastener is located, of the barrier plate.

9. The cooking device of claim 5 , wherein:
a fastening hole for fastening with a fastening member is formed in the fastening body,
the burner cover includes a first cover and a second cover, and
the fastening member is fastened to the fasting hole after passing through the first cover and the second cover.

10. The cooking device of claim 9 , wherein the opening includes a first opening provided in the first cover and a second opening provided in the second cover.

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

12. The cooking device of claim 11 , further comprising an ignition unit for igniting a mixed gas,
wherein a flange for preventing a wire connected to the ignition unit from being damaged is provided on the barrier member in the vicinity of the burner through-hole.
