The door includes an inner plate and a frame to form an opened lower end. The frame has holes formed in the upper side to flowing air discharged by the cooling fan between the inner plate and an outer plate. A vent hole communicating with the blower chamber is provided in the upper end of the cooking chamber to pass hot air of the cooking chamber through the vent hole. Around the vent hole, a partition member is provided for preventing the hot air from being mixed with air discharged by cooling fan.
