Abstract

A cooking appliance includes a main body forming a machine room; a cooking chamber arranged below the machine room; an intermediate flow path including a first suction port and formed between the machine room and the cooking chamber; and a fan configured to suction air into the intermediate flow path, wherein the machine room includes a second suction port through which air is suctioned, and an opening portion connected to the intermediate flow path, the opening portion includes a first opening portion and a second opening portion arranged at a farther distance from the fan than the first opening portion, and the second opening portion has an area larger than an area of the first opening portion.

First claim

What is claimed is:

1. A cooking appliance comprising:
a main body with a machine room;
a cooking chamber below the machine room;
an upper side cooking portion above the machine room;
an intermediate flow path formed between the machine room and the cooking chamber;
a fan configured to suction air into the intermediate flow path;
a discharge port opened upward to discharge air moved by the fan; and
a discharge cover that covers the discharge port in a vertical direction,
wherein the discharge cover includes:
a first through hole and a second through hole disposed above the discharge port, and through which air discharged from the discharge port passes in an upward direction,
an intermediate portion formed between the first through hole and the second through hole and disposed above the discharge port, and
a discharge guide protruding downward with a convex surface from the intermediate portion toward the discharge port so that the air discharged from the discharge port is guided to the first through hole and the second through hole along the convex surface.

2. The cooking appliance of claim 1 , wherein the first through hole and the second through hole are spaced apart in a forward and backward direction.

3. The cooking appliance of claim 1 ,
wherein the upper side cooking portion includes a cooking surface on which a cooking object is to be placed, and
the discharge cover includes an upper surface arranged parallel to the cooking surface.

4. The cooking appliance of claim 3 , wherein the discharge cover is disposed behind the cooking surface.

5. The cooking appliance of claim 1 , wherein the discharge guide protrudes downward from a lower side of the intermediate portion.

6. The cooking appliance of claim 5 , wherein the convex surface is convexly formed in a lower side direction.

7. The cooking appliance of claim 5 , wherein the discharge guide is detachably coupled to the of the discharge cover.

8. The cooking appliance of claim 1 , wherein the discharge cover includes:
a rear surface which extends downward from a rear end of an upper surface of the discharge cover and an additional through hole arranged in the rear surface and formed to allow air discharged from the discharge port to pass therethrough.

9. The cooking appliance of claim 8 , wherein the additional through hole is opened rearward of the cooking appliance.

10. The cooking appliance of claim 1 ,
wherein the cooking chamber includes a cooking chamber discharge port through which air inside the cooking chamber is discharged, and
the discharge cover covers the discharge port from an upper side of the cooking chamber discharge port.

11. The cooking appliance of claim 10 ,
wherein the upper side cooking portion includes a cooking surface on which a cooking object is to be placed, and
wherein the cooking chamber discharge port and the discharge port are disposed behind the cooking surface, and the discharge cover covers the cooking chamber discharge port and the discharge port behind the cooking surface.

12. The cooking appliance of claim 1 , wherein the machine room includes:
a suction port through which air is suctioned,
an opening portion through which air is introduced toward the intermediate flow path, the opening portion including a first opening portion and a second opening portion through which the air is introduced toward the intermediate flow path, and
wherein the second opening portion is arranged at a farther distance from the fan than the first opening portion and the second opening portion has an area larger than an area of the first opening portion.

13. The cooking appliance of claim 12 , wherein air is introduced into the machine room through the suction port to flow into the intermediate flow path through the first opening portion and the second opening portion.

14. The cooking appliance of claim 12 , further comprising:
a partition plate configured to divide the machine room from the intermediate flow path along an upper side and a lower side direction of the main body,
wherein the first opening portion and the second opening portion are formed at the partition plate.

15. The cooking appliance of claim 14 , wherein the partition plate has an upper surface that forms a lower portion of the machine room and has a lower surface that forms an upper portion of the intermediate flow path.
