閉鎖していた。At the time of cooking, food placed in a cooking chamber is cooked by high-frequency electromagnetic waves generated by a magnetron. At this time, the cooking room has a high temperature, and the high-temperature air is discharged to the outside together with the high-temperature air from the operation room. At this time, for example, an L-shaped space is provided between the heating chambers so that a portion of the heated air flowing into the cooking chamber does not circulate to the cooling air intake side of the operation chamber through the gap between the double roof boards. Separate parts such as angles were screwed in and attached to close the gap.

First, the configuration will be described. 1 to 3, a microwave oven 1 as an electronic device is a microwave oven 1 to which the cooling structure of the present invention is applied. The microwave oven 1 has a cooking room 2 and an operation room 5 in which devices such as a magnetron 3 and a high-voltage transformer 4 as cooking means are installed. The cooking chamber 2 is provided with a top plate 11 formed by an outer outer plate 11A and an inner inner plate 11B which are separated from each other for insulation from the outside and introduction of the waveguide of the magnetron 3;
It is integrally formed with the top plate 11 and is defined by a peripheral wall 11D formed substantially in the same manner as the top plate 11. Also,
The cooking chamber 2 can heat and cook food (not shown) by high-frequency electromagnetic waves generated by the magnetron 3 installed in the adjacent operation room 5. In the cooling structure, outside air for cooling is sucked in a direction indicated by an arrow by a fan 6 which is a cooling means provided in the operation room 5, and air cools the devices 3 and 4. After air cooling, the air is supplied to the air guide 7 in the operation room 5.
The gas is exhausted to the outside through a large number of holes 9 provided in the partition plate 8, through the cooking chamber 2, and through an exhaust hole 10. The top plate 11 of the microwave oven 1 is located on the outer plate 1
1A and an inner inner plate 11B, the opening 12 formed between the cooking chamber 2 and the operation chamber 5 is hollow.
Approximately half of the side provided with is shielded by extending the end of the inner plate 11B of the top plate (FIG. 2). The shield 14 is easily formed by simply bending the extension 13. Reference numeral 15 denotes a front door of the cooking chamber 2. 16
Is a waveguide set on the magnetron 3. 17
Is a lamp. Therefore, about half of the opening 12 on the side to which the cool air is sent by the cooling fan 6 remains as the opening 12 as shown in FIGS.
