9 . The cooking appliance of claim 8 , wherein the second gasket comprises a second sealing projection protruding from the second sealing body, and

the second sealing projection protrudes in a parallel direction with respect to the door rear surface cover with a flat surface being formed by the door rear surface cover.

10 . The cooking appliance of claim 8 , wherein the second support body comprises:

a first protrusion support part that protrudes in a parallel direction with respect to the door rear surface cover with a flat surface being formed by the door rear surface cover; and

a second protrusion support part that protrudes in a direction different from the direction in which the first protrusion support part protrudes while protruding in the parallel direction with the first protrusion support part,

wherein the second sealing body is disposed between the first protrusion support part and the second protrusion support part.

11 . The cooking appliance of claim 1 , wherein each third gasket comprises:

a third sealing body coupled to a bottom surface of the door upper surface part or a door frame and passes through the bottom surface of the door upper surface part or the door frame coupled to a lower portion of the door upper surface part in a front-rear direction; and

a third support body that supports the third sealing body in the door upper surface part,

wherein the third sealing body is disposed to face one lateral surface of the two lateral surfaces of the housing.

12 . The cooking appliance of claim 1 , wherein the second gasket is disposed between the pair of first gaskets, and the second gasket and the pair of first gaskets are arranged in a way that the second gasket and the pair of first gaskets connect in a “U” shape.

13 . The cooking appliance of claim 12 , wherein each of the pair of first gaskets comprises a straight line shape that extends in an up-down direction,

the second gasket comprises a straight line shape that extends in a left-right direction, and

the pair of third gaskets comprises a straight line shape that extends in a front-rear direction.

14 . A cooking appliance, comprising:
