Abstract

The present disclosure relates to a co'oking appliance. The cooking appliance includes an exhaust inducing part being disposed on at least any one of both lateral surfaces of a housing and creating a flow of air from the front of a cooking space to the rear surface of the housing, and a door provided with an air exhaust opening that forms a passage for discharging air in the door out of the door.

Claims (43)

1. A cooking appliance, comprising:

a housing having a cooking space defined by a bottom surface, two lateral surfaces and a rear surface of the housing, and having an open upper surface and an open front surface;

a door comprising a door upper surface part to cover the open upper surface of the housing and a door front surface part connected to a front side of the door upper surface part to cover the open front surface of the housing, and the door capable of swiveling about a rear side of the door upper surface part to open and close the open upper surface and the open front surface of the housing; and

an exhaust inducing part disposed adjacent at at least one of the two lateral surfaces of the housing to create a flow of air at a front of the cooking space,

wherein the cooking appliance comprises a hinge case disposed outside at at least one of the two lateral surfaces of the housing,

the hinge case having a cooling channel to guide a flow of the air flowing into the hinge case from an outside of the hinge case, and

the exhaust inducing part comprises the cooling channel, a channel inlet being open from the cooling channel to the outside of the hinge case, and a channel outlet being open from the cooling channel to an inside of the cooking space,

wherein the channel outlet penetrates in a lateral direction on a lateral surface of the hinge case facing the lateral surface of the housing.

2. The cooking appliance of claim 1 , wherein the door includes an air exhaust opening that forms a passage for discharging the air in the door to an outside of the door.

3. The cooking appliance of claim 1 , comprising a cool air discharge part communicating with the channel outlet disposed at the lateral surface of the housing, and

at least a portion of the air flowing into the cooling channel is discharged into the cooking space through the channel outlet and the cool air discharge part.

4. The cooking appliance of claim 3 , wherein the channel outlet and the cool air discharge part are disposed in the lateral direction, and at least a portion of the air flowing into the cooling channel is discharged in the lateral direction through the cool air discharge part.

5. The cooking appliance of claim 4 , wherein the exhaust inducing part comprises a discharge projection surrounding the channel outlet and protruding toward the lateral surface of the housing from the hinge case, and

the discharge projection connects between the channel outlet and the cool air discharge part.

6. The cooking appliance of claim 5 , wherein the cooling channel comprises a first section extending upward from the channel inlet disposed at a lower portion the hinge case, and a second section extending from an upper side of the first section rearward,

the first section is disposed adjacent to the open front surface of the housing, and

the second section is disposed adjacent to the open upper surface of the housing.

7. The cooking appliance of claim 1 , wherein the door upper surface part has a space therein,

the door upper surface part has an air exhaust opening at a rear end of the door upper surface part, and

the air exhaust opening penetrates the rear end of the door upper surface part and opens the space of the door upper surface part to the outside of the door.

8. A cooking appliance, comprising:

a housing having a cooking space defined by a bottom surface, two lateral surfaces and a rear surface of the housing, and having an open upper surface and an open front surface;

a door comprising a door upper surface part to cover the open upper surface of the housing and a door front surface part connected to a front side of the door upper surface part to cover the open front surface of the housing, and the door capable of swiveling about a rear side of the door upper surface part to open and close the open upper surface and the open front surface of the housing; and

the door includes an air exhaust opening that forms a passage for discharging the air in the door to an outside of the door,

wherein the door upper surface part has a space therein,

the door upper surface part has an air exhaust opening at a rear end of the door upper surface part, and

the air exhaust opening penetrates the rear end of the door upper surface part and opens the space of the door upper surface part to the outside of the door,

wherein a connection hole forming a passage connecting between the space of the door upper surface part and the cooking space of the housing is disposed at the door.

9. The cooking appliance of claim 8 , comprising a heating part disposed at the door.

10. The cooking appliance of claim 9 , comprising a door frame supporting the heating part and coupled to the door upper surface part,

wherein the connection hole is formed at the door frame.

11. The cooking appliance of claim 10 , wherein the door frame covers the space of the door upper surface part, and

the heating part is disposed at the door frame and under the door upper surface part.

12. The cooking appliance of claim 11 , wherein the door frame comprises:

a heater mounting part to which the heating part is coupled; and

a coupling part coupled to the door upper surface part to support the heater mounting part,

wherein at least a portion of the coupling part is disposed under the door upper surface part, and

the coupling part comprises a connection hole that penetrates in an up-down direction and forms a passage connecting between the space of the door upper surface part and the cooking space of the housing.

13. The cooking appliance of claim 12 , wherein the connection hole is disposed at a rear of the heating part, and

the heater mounting part is provided with a passage hole forming a passage connecting between a front and a rear of the heater mounting part.

14. The cooking appliance of claim 13 , wherein the passage hole penetrates the heater mounting part in a front-rear direction.

15. The cooking appliance of claim 13 , wherein the passage hole is disposed at a position where at least a portion of the connection hole overlaps with at least a portion of the passage hole in the front-rear direction.

16. The cooking appliance of claim 8 , wherein the cooking appliance comprises an exhaust inducing part disposed adjacent at at least one of the two lateral surfaces of the housing to create a flow of air at a front of the cooking space.
