<p>PURPOSE: To prevent a temperature of motor peripherals from rising, malfunctioning, and external leakage from giving a human body adverse influence, by intercepting micro wave in a heating room from leaking through a motor driving part and by disappear it naturally. CONSTITUTION: Microwave which is supplied into a heating room 1 leaks outside through a motor shaft and its penetrating hole 1b. The leaked micro wave gradually damps to disappear naturally, repeating the process where micro wave hits and reflects on a lot of cutoff projections which are circularly bent around the penetrating hole 4a in a cutoff member 4, and reflects again on a bottom wall 1a of the heating room 1. Because heat generated during the process is discharged outside through the penetrating hole 4b and an air hole 5a in a motor supporting member 5, temperature rising of motor's 3 peripherals and leaking of microwave are avoided.</p> |
