Cooking apparatus

A cooking apparatus comprising:

• a cooking chamber;
• a heater in an upper side of the cooking chamber to heat an inside of the cooking chamber;
• a door to open and close the cooking chamber, the door including:
• a door body having a portion that has an outer surface forming an upper outer surface of the door body, and an inner surface opposite the outer surface that is an upper inner surface of the door body, wherein the upper inner surface has a first upper inner surface at a front side of the upper inner surface and a second upper inner surface that is to a rear of the first upper inner surface and that is higher than the first upper inner surface, and the portion is recessed inward from the outer surface to form a handle, and
• a front panel coupled to a front of the door body and allowing the inside of the cooking chamber to be seen from an outside of the cooking apparatus;
• and
• a cooling plate to a rear of the handle and including:
• a first plate portion in contact with the first upper inner surface to allow heat generated by the heater to flow around the handle to the first upper inner surface,
• a second plate portion bent downwardly from an end of the first plate portion and in contact with a front wall of the door body to allow heat which is generated by the heater and transferred through the handle and the first plate portion, to be transferred to the door body, and
• a third plate portion extending upward from the first plate portion and in contact with the second upper inner surface to allow heat generated by the heater to flow around the handle to the second upper inner surface,
• wherein the front panel, the door body, and the cooling plate are sequentially in contact with each other to transfer heat from the cooling plate toward the front panel.
