るマイクロ波加熱装置の電波漏洩防止構造。 A door is provided at the opening of the heating chamber so that it can be opened and closed, and the inner surface of the door is opposed to the end surface of the opening of the heating chamber when the door is closed.
A high frequency attenuator having an odd multiple of approximately λ/4 (λ: wavelength in air) is formed inside the frame-shaped portion of the door, and an eave-like attenuator is formed perpendicular to the end surface of the opening of the heating chamber and facing the side surface of the door. A flat radio wave absorbing member is disposed on a flat plate surface, and the middle portion of the flat radio wave absorbing member is approximately λ from the maximum electric field position which is the open end of the high frequency attenuator.
The first portion of the radio wave absorbing member, which extends to the side opposite to the door side surface when viewed from the electric field minimum position, has an arbitrary length, and The second part of the radio wave absorbing member extending to the opposite side of the first part is set to have a length that is an integral multiple of approximately λ'/2 (λ': wavelength within the radio wave absorbing member). Radio wave leakage prevention structure for microwave heating equipment.
