本考案はマイクロ波加熱の他に熱風加熱をも行

されて加熱室２内に矢印の如く熱風が循環する。 In a conventional microwave oven of this type, as shown in FIG. 1, a metallic U-shaped cross-section cover 3 is placed on the upper wall of a heating chamber 2 to which microwaves from a magnetron 1 are supplied, with its opening 4 facing downward. A metal fan 7 driven by a heater 5 and a motor 6 is disposed inside the cover 3, and a radio wave transparent ceramic cover 9 is provided with openings 8, 8, 8 at appropriate locations. The opening 4 of the U-shaped cover 3 is closed. Then, the microwave is stirred by the fan 7, and air is supplied to the heater 5, so that the hot air circulates in the heating chamber 2 as shown by the arrow.
しかるに、斯る構造であると、上記フアン７の

ている。 However, this structure has the disadvantage that, because the U-shaped cover 3 surrounding the fan 7 is made of metal, sufficient stirring by microwaves is not achieved. Furthermore, the heater 5 and the fan 7
Two parts, the above-mentioned U-shaped cover 3 and ceramic cover 9, are required to cover the body, resulting in high cost.
本考案は斯る点に鑑みてなされたもので、以下
本考案実施例電子レンジを第２図に基づいて詳述

バー１７の中心部及び角部に設けられた吸気口及
び吐出口である。 10 is a heating chamber in which the food 11 is stored; 12 is a magnetron that supplies microwaves into the heating chamber 10 from a power supply port 13 on the upper wall of the heating chamber; 14 is a heater disposed in the upper part of the heating chamber 10; 15 17 is a radio wave-transparent ceramic cover with a U-shaped cross section, which is arranged inside the heater and driven by a motor 16 outside the heating chamber 10; It is fixed to the upper wall of the heating chamber 10 with screws 18, 18, so as to house the heater 14 and the fan 15 together with one wall, that is, the upper wall, of the heating chamber 10. Reference numerals 19, 20, and 20 are intake ports and discharge ports provided at the center and corners of the cover 17, respectively.

０，２０の一部は加熱室１０側壁に対向している
から、熱風は加熱室１０内を従来に較べてより広
く循環し、従つて加熱室１０内の温度分布はより
均一となる。 Thus, the microwave is stirred by the rotation of the fan 15. Further, the fan 15 is connected to the heating chamber 1.
The air below 0 is taken into the ceramic cover 17 through the intake port 19, and the air heated by the heater 14 is sent into the heating chamber 1 through the discharge ports 20, 20.
0 downward, thereby circulating hot air within the heating chamber 10. Here, since the cover 17 is not made of metal, the microwaves are not affected by the cover 17 and are sufficiently stirred. Further, the discharge ports 20, 20 are provided at the corners of the cover 17, and the discharge ports 20, 20 are provided at the corners of the cover 17.
Since a portion of the heating chamber 10 faces the side wall of the heating chamber 10, the hot air circulates more widely within the heating chamber 10 than in the past, and therefore the temperature distribution within the heating chamber 10 becomes more uniform.

コスト化を図ることができる。 Thus, according to the present invention, the heating chamber is heated with the fan and heater for microwave stirring and hot air circulation housed therein, and the fan and heater are covered with one wall of the heating chamber. Since a radio wave transparent cover with a U-shaped cross section is provided, which is fixed to one wall, uniform microwave heating can be performed, and a high-performance microwave oven can therefore be provided. Furthermore, only one radio wave transparent cover is required as a separate part for covering the heater and fan, and therefore the cost of the microwave oven can be reduced.
