Abstract

The present disclosure relates to a cooking appliance. The cooking appliance includes an exhaust inducing part creating at least any one of a flow of air from any one lateral surface of a housing to the other lateral surface of the housing out of both lateral surfaces of the housing and a flow of air from the front of a cooking space to the rear surface of the housing, while being disposed on a lateral surface of the housing and creating a flow of air at the front of the cooking space.

Claims (37)

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 is 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;

a hinge case disposed at at least one of the two lateral surfaces of the housing; and

an exhaust inducing part disposed at the 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 exhaust inducing part creates the flow of air to an other lateral surface of the two lateral surfaces of the housing, and the flow of air to the rear surface of the housing from the front of the cooking space,

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

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 cooking appliance further comprising a cool air discharge part communicating with the channel outlet at the at least one of the two lateral surfaces of the housing,

wherein the exhaust inducing part comprises a discharge projection surrounding the channel outlet and protruding toward the at least one of the two lateral surfaces of the housing from the hinge case,

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

2 . The cooking appliance of claim 1 , wherein the cool air discharge part comprises a plurality of discharge openings that penetrates the at least one of the two lateral surfaces of the housing.

3 . The cooking appliance of claim 1 , wherein the channel inlet is open to a lower portion of the hinge case, and

a cooling fan is disposed at the channel inlet.

4 . The cooking appliance of claim 1 , wherein 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.

5 . The cooking appliance of claim 1 , wherein the channel outlet penetrates in a lateral direction on a lateral surface of the hinge case facing the at least one of the two lateral surfaces of the housing.

6 . The cooking appliance of claim 5 , wherein the channel outlet and the cool air discharge part are disposed in the lateral direction, and the at least a portion of the air flowing into the cooling channel is discharged in the lateral direction through the cool air discharge part.

7 . 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 is 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;

a hinge case disposed at at least one of the two lateral surfaces of the housing; and

an exhaust inducing part disposed at the 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 exhaust inducing part creates the flow of air to an other lateral surface of the two lateral surfaces of the housing, and the flow of air to the rear surface of the housing from the front of the cooking space,

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

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 inlet is open to a lower portion of the hinge case, and a cooling fan is disposed at the channel inlet,

wherein the channel inlet has a greater width than the cooling channel, in a parallel direction with respect to the bottom surface of the housing,

a fan mounting part surrounding the channel inlet and protruding from the lower portion of the hinge case in the parallel direction with respect to the bottom surface of the housing is disposed at the lower portion of the hinge case, and

the cooling fan is disposed in the fan mounting part.

8 . The cooking appliance of claim 7 , wherein the fan mounting part protrudes from the lower portion of the hinge case to the bottom surface of the housing,

a space formed under the bottom surface of the housing is open toward the hinge case in the lateral direction, and

at least a portion of the fan mounting part is inserted into the space formed under the bottom surface of the housing.

9 . The cooking appliance of claim 7 , wherein front-to-rear positions of the cooling channel and the channel outlet are biased toward the door front surface part.

10 . The cooking appliance of claim 7 , wherein an up-to-down position of the channel outlet is biased toward the door upper surface part.

11 . The cooking appliance of claim 7 , wherein the cooling channel comprises a first section extending upward from the channel inlet that is disposed at the lower portion of the hinge case, and a second section extending from an upper side of the first section rearward,

the first section is disposed adjacent to a front side of the at least one of the two lateral surfaces of the housing and the door front surface part, and

the second section is disposed adjacent to an upper side of the at least one of the two lateral surfaces of the housing and the door upper surface part.
