Abstract

A cooking apparatus includes a frame configured to form a cooking chamber; a burner cover provided inside the frame and configured to form a combustion chamber; a burner accommodated in the combustion chamber; a fan provided at an outside of the burner cover in the frame; and a fan cover configured to cover the fan and the burner cover.

First claim

What is claimed is:

1. A cooking apparatus comprising:
a frame having a cooking chamber;
a burner cover fastened to a rear wall of the frame to form a combustion chamber;
a burner provided within the combustion chamber;
a fan provided at a front of the burner cover in the frame; and
a fan cover fastened to the burner cover to cover the fan and the burner cover,
wherein the burner cover covers a front of the burner and a rear of the burner,
wherein the burner cover includes a fan accommodation portion in which at least a part of the fan is accommodated,
wherein the fan accommodation portion is formed by recessing a front surface of the burner cover toward the rear wall of the frame, and
wherein the fan is located between the fan cover and the burner cover.

2. The cooking apparatus of claim 1 , wherein the frame includes an air introduction hole through which air outside the frame is introduced into the frame, and the burner cover covers the air introduction hole, the burner cover having an air introduction opening through which the air passed through the air introduction hole is introduced into the combustion chamber.

3. The cooking apparatus of claim 2 , wherein the burner cover includes an air introduction guide having a plurality of air introduction openings, and
the plurality of air introduction openings are arranged along a circumference of the air introduction guide.

4. The cooking apparatus of claim 3 , wherein the burner is provided outside of the air introduction guide, and
at least a part of the burner is arranged to surround the circumference of the air introduction guide while being spaced apart from the air introduction guide.

5. The cooking apparatus of claim 2 , wherein the burner cover further includes at least one air through-hole through which the air introduced into the combustion chamber passes, and
the air introduced into the combustion chamber through the air introduction opening is heated by a flame of the burner, to pass through the at least one air through-hole.

6. The cooking apparatus of claim 5 , wherein the burner cover includes a plurality of the air through-holes, and
the plurality of the air through-holes are arranged along a circumference of the fan in the burner cover.

7. The cooking apparatus of claim 2 , further including a fan motor to rotate the fan,
a shaft of the fan motor passing through the frame and the burner cover and being connected to the fan.

8. The cooking apparatus of claim 2 , wherein the fan cover and the burner cover form an air flow chamber, and
the fan cover having an air inlet port through which air in the cooking chamber is introduced into the air flow chamber, and an air outlet port through which the air in the air flow chamber is discharged to the cooking chamber.

9. The cooking apparatus of claim 8 , wherein the air introduced into the combustion chamber through the air introduction opening is heated in the combustion chamber, introduced into the air flow chamber, and discharged into the cooking chamber through the air outlet port together with the air introduced from the cooking chamber into the air flow chamber.

10. The cooking apparatus of claim 1 , wherein the burner cover includes an air introduction guide having a plurality of air introduction openings, and
the air introduction guide extends toward the fan.

11. The cooking apparatus of claim 10 , wherein the fan accommodation portion is in contact with the air introduction guide.

12. The cooking apparatus of claim 11 , wherein the burner cover includes a first cover which has the fan accommodation portion, and a second cover which is fastened to the first cover and has the air introduction guide.

13. The cooking apparatus of claim 1 , further including a single fastener which fastens the burner cover, the fan cover and the frame at a time together.

14. The cooking apparatus of claim 1 , wherein
a part of the burner cover is located between the fan and the burner,
the burner being arranged closer to the frame than the fan.
