Furthermore, since the cover is microwave permeable, there is no need to provide a gap between the cover and the side wall of the heating chamber in order to suppress the generation of electric discharge, and the above-mentioned cover is microwave-transmissive so that sufficient microwave heating can be performed. There is no need to provide an opening 4 in the cover, and therefore, when an air passage is formed between the cover and the upper wall of the heating chamber, the air does not leak undesirably from the air passage, and the air passage can perform its function satisfactorily. to accomplish.

Inside the heating chamber (1), a waveguide (
3) and a power supply port (5) on the upper wall of the heating chamber (4) to which microwaves are supplied for microwave heating. A sheathed heater (6) is provided for this purpose. In this case, the power supply port (5) is provided with a heat-resistant insulating cover (7). This results in
The high heat from the heater (6) is not transmitted to the earthen wall (4) near the heater (6), so the upper wall (4) may be thermally deformed, or the high heat may be transferred from the earthen wall (4) to the waveguide ( 3) will not be transmitted to the magnetron (2) and the performance of the magnetron (2) will not deteriorate. Furthermore, since the cover (7) is microwave permeable, it is possible to suppress the occurrence of electrical discharge without providing a gap between the cover (7) and the heating chamber side wall (8) as in the conventional case. Even without providing a separate opening in the cover (7) as in the conventional case, the microwaves can smoothly reach downward from the power supply port (5) and the food can be sufficiently heated.

分なる機能を発揮する風路を形成できる。The cover (7) forms an air passage (9) between the earthen wall (4) and the upper wall (4).
9) is an exhaust port (11) formed on the side wall (8) and a cover (7) to direct the wind introduced from the intake port +101 on the top wall (4).
These exhaust ports (11) (12+) are used to discharge air from other exhaust ports (12) formed in the above-mentioned other exhaust ports (12).
The air discharged from the door (13) follows the inner surface of the door (13).
) The inner surface is prevented from becoming cloudy due to water vapor. in this case,
According to the present invention, the air introduced into the air passage (9) does not leak undesirably because there are no gaps or openings as in the conventional case, and therefore the air passage (9) can fully perform its function. For example, the heating chamber can be heated without causing thermal deformation of the upper wall of the heating chamber or deterioration of the magnetron's performance due to high heat from the heater, and while ensuring that sufficient microwave heating can be performed without causing electrical discharge. A fully functional air passage can be formed between the room and the walls of the room.
