In order to achieve the above object, the micro-wave oven that provides of the utility model comprises the external box of microvave that constitutes micro-wave oven end face, bottom surface, two sides and back side external structure; Be arranged on inside one side of external box of microvave, place the heating cavity for the treatment of cooking food within it on the rotating disk that can be provided with; Be arranged on the opposite side of external box of microvave inside, the various electronic components such as magnetron, high-tension transformer and fan that can produce microwave are installed in it, and front end be provided with the electric control chamber of the control panel that can control running of microwave oven; Be arranged on the front end face and the alternative fire door that opens and closes heating cavity of external box of microvave; With the rear portion that is arranged on the micro-wave oven back side, be connected with external box of microvave, and the inner surge chamber that radiator fan is installed; Described micro-wave oven also comprises a rear portion that is arranged on heating cavity in the external box of microvave, is connected with the inside of heating cavity, and the inner hot air generator installation room that hot air generator is installed.
Described heating cavity is drum shape.
The left upper portion of described heating cavity is formed with a wind guide tank that is connected with the surge chamber that is positioned at the external box of microvave rear portion.
The rear portion of described surge chamber is formed with the exhaust outlet that can discharge air.
The micro-wave oven that the utility model provides is to utilize the radiator fan that is positioned at surge chamber inside to come heat of cooling wind generation apparatus installation room and discharge from the inner air that flows out of heating cavity, not only can reduce the temperature of hot air generator so rapidly, and can reduce the thermal loss of heating cavity inside, thereby improve the thermal efficiency of micro-wave oven.
