締着してなる。As shown in FIG. 2, the duct 11 consists of metal duct parts 11a and 11b attached to the wall of the heating chamber 2, and a duct part 11C made of a material transparent to radiant heat such as quartz. These metal duct parts 11a, llb and the radiant heat ray transparent duct part 11C are joined and fastened together with screws 17.
電気ヒーター１０は輻射熱線透過性ダクト部１１ Ｃに
内蔵してある。The electric heater 10 is built in the radiant heat transmitting duct section 11C.
輻射熱線透過性ダクト部１１ Ｃを介して後述する透孔

を受容すべく輻射熱線反射板１８が配設されている。This radiant heat ray transparent duct 11C is located at a position facing a through hole, which will be described later, through the radiant heat ray transparent duct part 11C.
A radiant heat ray reflecting plate 18 is provided to receive the radiant heat rays.
更に、輻射熱線透過性ダクト部１１Ｃと対向する加熱室
２壁に電波遮蔽用透孔１９を形威してある。Further, a radio wave shielding through hole 19 is formed in the wall of the heating chamber 2 facing the radiant heat transmitting duct portion 11C.
この電波遮蔽用透孔１９は加熱室２壁の一部を切欠しこ
の切欠してなる部分に張設した導電性板材２０に形或さ
れている。This radio wave shielding through hole 19 is formed in a conductive plate material 20 that is cut out from a part of the wall of the heating chamber 2 and stretched over the cut out part.

る。Since this device is constructed as described above, it is possible to brown the object to be heated with high-temperature hot air, and the radiant heat rays of the heater are reflected directly and by the radiant heat ray reflector, so that the duct wall and the radio wave shielding transparent material can be heated. The heating chamber is irradiated through the holes, so the duct wall is not heated by radiant heat, and the amount of wasted heat dissipated from the duct wall to the outside can be reduced.Therefore, a microwave oven equipped with a hot air circulation device with high heat exchange efficiency can be used. Can be provided.
