Description of the Related Art An example of a conventional heating cooker having both the functions of a microwave oven using hot air circulation and high-frequency heating is not shown in FIGS. 3 and 4. 12 is a drive motor, 13 is a cooling fan, and 14 is a hot air circulation device. A cooling fan 13 mainly blows air for self-cooling of the drive motor 12 and for cooling the hot air circulation device 14 above. With the recent miniaturization of cooking appliances, the gap between the cooling fan 13 and the top plate 15 of the main body has become narrower.

ることになる。Problems to be Solved by the Invention However, in the conventional example described above, since a propeller fan is used as the cooling fan 13, the cooling air flowing in the axial direction hits the upper top plate 15 of the main body and is dispersed in all directions. , the −L side of the hot air circulation device 14 cannot be efficiently cooled. For this reason, it is necessary to use highly heat-resistant resin parts such as electric wires arranged on three sides of the hot air circulation device 14, and the surface temperature of the top plate 15 at the top of the main body becomes considerably high, so that if you touch it, This poses safety problems such as the risk of burns, and also leads to increased costs.
さらに、駆動用モータ１２自体も送風が不十分で５かつ
拡散した風が天板に当り逆流するため自己冷却も効率的
に行えず、巻線や軸受の温度も高いままで使用されるこ
ととなり、信頼性の面からも問題がある。Furthermore, the drive motor 12 itself is not sufficiently blown, and the diffused air hits the top plate and flows backwards, so self-cooling cannot be performed efficiently, and the windings and bearings end up being used with high temperatures. However, there are also problems in terms of reliability.

上昇を抑えることができる。Function The present invention provides a drive motor equipped with a cooling fan in the vicinity of the hot air circulation device as described above, and provides a blowing guide along the upper surface of the hot air circulation device from the outer periphery of the cooling fan. The air from the fan can be efficiently guided above the hot air circulation device without being dispersed, and since the gap between the air guide and the upper top plate of the main body is closed with a liner, the air does not flow backwards. The self-cooling of the drive motor has become more efficient. Therefore, increases in the temperature above the hot air circulating device and the surface temperature of the upper top plate of the main body can be suppressed.
