A cooking apparatus is provided. The cooking apparatus includes a cooking cavity, an upper space formed above the cooking cavity, lateral side spaces formed to at opposite lateral sides of the cooking cavity, a rear space formed behind the cooking cavity, and a lower space formed below the cooking cavity. A fan provided in the rear space generates a cooling flow that cools components housed in the rear space. A cooling flow path extends from the rear space and into the upper space and lateral side spaces. Flow from the upper space enters the door to cool the door and is exhausted through a lower portion of the door. Flow from the lateral side spaces, which includes an exhaust flow from the cooking cavity, is guided to the lower space and exhausted. In this manner, the cooking apparatus can be completely cooled and cooking odors and heat appropriately exhausted by the cooling fan positioned in the rear space.

The cooking apparatus of claim 8, wherein an upper space is formed between an upper outer surface of the cooking cavity and an external case of the cooking apparatus, and wherein the cooling flow path extends from the upper space of the cooking cavity to the upper portion of the door, and the bracket is positioned in a portion of the cooling flow path which is at the upper portion of the door. 10. The cooking apparatus of claim 9, further comprising: a front frame positioned at a front surface of the cooking cavity, wherein the front frame includes a frame opening in communication with the cooling flow path; anda door opening provided in the door, wherein the door opening is in communication with the frame opening such that cooling flow passing through the frame opening enters into an interior of the door. 11. A cooking apparatus, comprising: a cooking cavity;an upper space formed over the cooking cavity;a rear space formed behind the cooking cavity;a door configured to cover the cooking cavity; andan operation panel provided in the door;a cooling flow path that extends from the rear space, through the upper space, and into the door, wherein the cooling flow path directs cooling air into the door and prevents heat from the cooking cavity from reaching the operation panel; anda bracket installed in an upper portion of the door, at a position corresponding to the control panel and to a portion of the cooling flow path at which cooling air from the upper space enters the door, wherein the bracket is configured to direct cooling air down into the door, and away from the operation panel. 12. The cooking apparatus of claim 11, wherein the door comprises: a door panel;a front plate coupled to a front surface of the door panel;a door frame coupled to a rear surface of the door panel;a middle plate positioned between the door panel and the door frame; anda choke cover coupled to a rear surface of the door frame, wherein the bracket is positioned between an upper portion of the door panel and an upper portion of the choke cover. 13. The cooking apparatus of claim 12, wherein the operation panel comprises: an input sensor installed between the front plate and the door panel; anda control panel installed between the door panel and the bracket. 14. The cooking apparatus of claim 13, further comprising a front frame coupled to a front surface of the cooking cavity, wherein the front frame comprises at least one opening positioned corresponding to a front side of the upper space, and wherein the choke cover comprises a plurality of openings formed in an upper portion thereof, in a position corresponding to the at least one opening formed in the front frame. 15. The cooking apparatus of claim 14, wherein the flow path is configured to direct cooling air from the upper space through the at least one opening in the front frame, through the plurality of openings formed in the choke cover, and into an interior of the door. 16. The cooking apparatus of claim 14, wherein the bracket comprises an inclined surface positioned corresponding to the plurality of openings in the choke cover, wherein the inclined surface is configured to direct cooling air flow entering the door downward into an the interior of the door. 17.
