インピーダンスの変化で高周波が減衰され、加熱室２内
から外部への電波漏洩が防止される。For example, if you press the high-frequency heating selection key, the high-frequency oscillator (
(not shown) is supplied into the heating chamber 2,
Dielectrically heats the object to be heated. The high-frequency waves supplied into the heating chamber 2 are prevented from leaking by a choke groove 11 provided on the inner peripheral edge of the door 3, and are further prevented from leaking by a gap B between the heating chamber wall 23 and the door inner plate 9. Since the dimension of the gap A that communicates the four parts 20 provided on the door outer panel 12 is made smaller than the depth of the recess 20 and the gap B, the impedance changes reflect into the heating chamber 2, further heating By making surface contact between the opening peripheral plate 21 of the chamber 2 and the door outer plate 12 and reducing the mechanical gap to zero, high frequencies are attenuated due to a sudden change in impedance, and radio wave leakage from inside the heating chamber 2 to the outside is prevented. Prevented.

高めることができる。Furthermore, if the heating chamber 2 and the object to be heated are heated with an electric heater (not shown), the heated air and water vapor generated from the object to be heated will flow into the recess 20 through the gap B and the gap A'ff. Since a gasket 22 made of a heat-resistant elastic material is provided in this recess 20, it will not flow out of the main body 1, and since the gasket 22 is provided near the heating chamber 2, excess heat will not be heated. It is possible to increase heating efficiency without having to

を有する。Also, the door outer plate 12 is opposite to the opening peripheral plate 21 of the heating chamber 2.
By providing the gasket 22 made of a heat-resistant elastic material in the recess 2o of the heating chamber 2, hot air and steam will not flow out from the heating chamber 2 to the outside of the main body 1. Because of this provision, the volume and area to be heated are reduced, and a high-frequency heating device with higher heating efficiency and no leakage of radio waves can be obtained.
