A microwave oven is installed above a cooking counter such as a kitchen stove counter. The microwave oven has its housing covered by an oven case, and incorporates a fan. By driving the fan, the microwave oven can have the hot air generated at the cooking counter inhaled from beneath the oven case and discharged from a front opening. The front opening is formed at the front face of the oven case. An operation display device is provided at the front face of the oven case. By one operation of a predetermined key on the operation display device, the drive of the fan is initiated and then automatically terminated at an elapse of a predetermined time (for example, 10 minutes).

High frequency heating apparatus with fan sending air below apparatus to predetermined direction

When a hood fan of a microwave oven installed at a high place operates, the air below the microwave oven is guided to a prescribed direction. Namely, the microwave oven may be used as a ventilation fan. When manner of setting of the hood fan is changed, the direction of an air outlet of the fan can be changed. When the hood fan exhausts air to the room, the number of rotation of the hood fan is made lower than when the air is exhausted outside the room.

A microwave oven includes electronic components such as a high voltage transformer and a high voltage capacitor constituting a control circuit. These components are provided on a bottom panel of the microwave oven. A filter is fit under the bottom panel of the microwave oven. By removing the filter, the bottom panel can be detached from the main body frame. By detaching the bottom panel from the main body frame, the electronic components such as the high voltage transformer and the high voltage capacitor can be removed from the main body of the microwave oven while the microwave oven is still mounted at a high position. A cooking appliance that can be easily handled is provided.

A high frequency heating device having a switching member screwed into a screw hole formed in a flange and fixed to the exterior. When the exterior is fixed to the body, a through-hole formed at that portion in the rear plate of the body through which the switching member passes is too large for the switching member. Thus, while the switching member is fixable to the exterior, the switching member cannot be fixed to the body onto which the exterior is not mounted. Therefore, a high frequency heating device can be provided, wherein an exterior switch more surely keeps the power supply circuit open when the exterior is removed.
