<p>PURPOSE:To increase the strength of receptacles and to accomplish uniform heating of substances to be heated, by forming a plurality of microwave transmitting slits in the receptacles made of metal plate. CONSTITUTION:Receptacles 8-10 made of metal plate are formed with handholds 15 which are made of a heat-resisting, insulating material. These receptacles 8-10 are supported at the handholds 15 on the wall 2 or support metals 14 in a heating chamber in an electrically insulating manner. Further, over the entire region of the receptacles 8-10, there are formed many microwave transmitting slits 16. With such an arrangement, it is enabled to heat a large amount of food by microwaves by inserting or drawing out the receptacles 8, 9 selectively. Further, since the microwaves are irradiated uniformly throughout the entire space of small chambers 12, 13 through the many slits 16, food in small chambers 12, 13 can be heated uniformly.</p> |
