Air taken in from outside the main body 1 cools the magnetron 2, transformer 3, condenser 4, etc., and is exhausted to the outside of the main body 1 through exhaust ports provided on the surface of the main body 1 where no air intake ports are provided. The air that has cooled the components removes heat from them and is exhausted at a high temperature. However, especially the air exhausted from the bottom of the main body 1 is exhausted radially, partially flows in the direction of the arrow (ⓓ), returns to the intake side, is taken in as intake air, raises the intake air temperature, and changes the atmosphere inside the main body 1. In order to increase the cooling effect, the cooling effect is reduced.
In particular, microwave ovens are installed in corners, etc.
When the intake direction or the space around the main body 1 is restricted, there is no margin in the amount of intake air, and even hotter exhaust gas is taken in, increasing the intake air temperature and further deteriorating the cooling effect.

Therefore, a shielding plate 8 is provided on the bottom surface of the main body 1 to separate the exhaust air from the intake air and prevent the exhaust air from going around to the intake air. As a result, the intake air and exhaust air are completely separated and shut off, and as shown in Figure 2, the intake air temperature decreases and the main body 1
The internal atmospheric temperature also decreased, increasing the cooling effect. Especially when placed in a corner, the effect of the shielding plate 8 is great, and the results are comparable to those of normal installation.In one embodiment of the present invention, the shielding plate is placed on the bottom of the main body. By completely separating the exhaust path and intake path using the bottom of the main unit, the shield plate, and the outer wall, the exhaust gas containing hot air discharged from the bottom of the main unit is prevented from going around to the intake side, and the rise in intake air temperature is prevented. It is possible to suppress the temperature rise of the presser foot, magnetron, transformer, etc., and even under the worst usage conditions, such as when installed in a corner or with limited space around the main body, it is possible to suppress the temperature rise of the presser foot, magnetron, transformer, etc. 180℃)
It became possible to satisfy the following.

As a result, even under conditions of abuse, the temperature can be kept within the insulation type's limit temperature, ensuring safety in terms of insulation performance, reducing defects due to thermal factors, and increasing reliability. Even when achieving the same performance, improved cooling performance allows the transformer to be made smaller and lighter, resulting in cost benefits.
Also, regarding the shielding plate that separates the exhaust passage and the intake passage by the bottom surface of the main body, the shielding plate, and the outer wall, a simple plate-like structure may be used, especially when it is provided on the bottom surface.
A complicated configuration for forcibly directing the exhaust gas is not required and can be obtained at low cost. Also, there are some points where it is not necessary to consider the appearance.
