Description of the Related Art In a cooking device such as a microwave oven with an oven function, for example, it is used by placing it on a table or at a relatively high position such as a lower surface of a hanging cabinet. There is a case. When installing a microwave oven on the bottom side of such an installation shelf, so to speak,
Conventionally, as shown in FIG. 5, a microwave oven main body 1 is housed in a support box 2 which is vertically and deeply larger than a microwave oven main body 1, and the back surface of the support box 2 is directed to a chamber wall 3. While doing so, the upper surface of the support box 2 is attached to the installation shelf 4.

がある。In this case, as is well known, in order to cool the electric components such as the magnetron during operation, a fan device provided in a machine room in the main body 1 is driven so that a suction hole is formed in the rear surface of the main body 1. After the cooling air is taken in and used for cooling the parts, the air is discharged from the discharge hole on the upper surface of the main body 1. Also, when cooking with heat, especially when cooking with an oven,
Since the support box 2 has a high temperature, it is necessary to cool it.

However, there is a problem that the support box 2 becomes large in the front-rear direction. Further, since the back portion of the support box 2 is installed so as to be in close contact with the chamber wall 3, the high temperature of the support box 2 is transmitted to the chamber wall 3 particularly during cooking in an oven, and the temperature of the chamber wall 3 becomes high. There was also a problem.

When the cooking is being performed, the cooling fan 20 in the main body 11 is driven and the fan device 35 in the air flow path 30 is driven. As a result, as shown by the outline arrow in FIG. 1, the outside air is taken into the air flow passage 30 from the intake port 33 of the decorative panel 32 as cooling air,
After flowing through the air flow path 30 and being used for cooling the electric components such as the magnetron 17 in the main body 11 (machine room 13), the outer box 12, the support box 24, etc., the air is discharged from the exhaust port 34 to the outside.

Now you can do it. As a result, unlike the conventional one that requires the large air passage 5 on the back side of the main body 1, even if the air passage 30 on the back side of the main body 11 is narrowed, sufficient cooling capacity can be secured. As a result, the support box 24 can be downsized in the front-rear direction.

る。As is apparent from the above description, according to the heating cooker of the present invention, the main body is housed in the support box, and the chamber wall surface and the support box are installed. Since a projection for forming a gap with the rear part of the support box is provided and an opening for intake is provided in the rear part, a small size in the front-rear direction of the support box is ensured while ensuring sufficient cooling capacity. It is possible to achieve high temperature, and at the same time, it is possible to prevent the temperature of the wall surface of the chamber from becoming high.
