ることができた。In FIG. 6, a heating chamber 2 for heating an object to be heated is provided inside a main body 1, and the bottom surface of the main body 1 is composed of a bottom plate 3 having ventilation holes on the bottom surface. A machine chamber 4 is provided below the heating chamber 2 and above the bottom plate 3, and a blower device 6 for cooling the electric components 5 for driving the high-frequency heating device is provided in the machine chamber 4, and the blower device is provided. 6, a blower device 6 is partitioned from the electrical component 5 that is the object to be cooled,
The blower device 6 is provided with a partition plate 7 for the purpose of sucking cool air outside the main body as much as possible to improve the cooling capacity. Below the ventilation holes of the bottom plate 3, bottom plate fittings 8 having ventilation holes on the bottom surface and side surfaces are provided. Again 9
Is a stand for the high-frequency heating device, 10 is a sheet for preventing the stand 9 from being contaminated by an object to be heated, or an antibacterial sheet for preventing cockroaches from being made of nylon or polyethylene of various thicknesses and masses. It is a thing. Next, the operation will be described. When the blower 4 operates, the blower 4 tries to take in air from everywhere, but inside the machine room 4, the blower 6 and the electric component 5 are partitioned by a partition plate 7. Therefore, most of the outside cool air is taken in from the ventilation holes of the bottom plate 3 through the ventilation holes on the bottom surface and the side surface of the bottom plate metal fitting 8 having a low intake resistance. At this time, the larger the suction force of the blower 6 is, and the smaller the mass of the seat 10 is and the thinner and softer it is, the more the seat 10 is sucked to the bottom surface of the main body 1. For example, when the seat 10 is adsorbed by the blower 6 only to the ventilation holes on the bottom surface of the bottom plate metal fitting 8, it becomes impossible to inhale through the ventilation holes on the bottom surface of the bottom plate metal fitting 8, but since the intake air on the bottom surface has disappeared, the ventilation holes on the side surface are eliminated. Since the intake pressure from the inside increases, the blower 6 can inhale the cool air outside the main body 1 regardless of adsorption to the bottom surface of the seat 10, and the cooling performance of the electric parts can be secured.

In order to increase the capacity, it is necessary to increase the intake force as well.In that case, the seat laid on the stand will adsorb not only on the bottom surface of the bottom plate metal fittings but also on the ventilation holes on the side surfaces, and intake from outside It becomes sufficient, and the air blower draws in hot air from the gap throughout the machine room, and the intake air temperature rises. As a result, there is a problem that the cooling performance of the electric parts becomes insufficient and the electric parts are broken.

Inhale cold air. At this time, if the seat 10 laid on the stand 9 is adsorbed to the bottom and side vents of the bottom plate fitting 8 by the suction force of the blower 6, it is not possible to take in air from the bottom and side vents of the bottom plate fitting 8. However, the auxiliary vent hole provided at the end of the bottom plate fitting 8 vertically upward with respect to the bottom surface allows the seat 10 to be sucked without being adsorbed. Also,
Since the bottom and side vent holes of the bottom plate fitting 8 are blocked to make it impossible to take in air, the intake pressure of the vent hole provided at the end of the bottom plate fitting 8 vertically above the bottom surface assists the seat 10.

At this time, if the seat 10 laid on the stand 9 is adsorbed to the ventilation holes on the bottom surface of the bottom plate 3 by the suction force of the blower 6, it becomes impossible to intake air from the ventilation holes on the bottom surface of the bottom plate 3. The sheet 10 is not adsorbed to the auxiliary vent hole provided on the side surface of the sheet and can be inhaled. In addition, since the ventilation holes on the bottom surface of the bottom plate 3 are blocked to make it impossible to inhale air, the intake pressure of the ventilation holes provided as an auxiliary on the side surface of the bottom plate 3 is increased.
Since 0 increases as compared with the case where the bottom surface of the bottom plate 3 is not adsorbed, the intake amount of the air blowing device 6 is the same as that when the seat 10 is not adsorbed to the bottom plate 3, and the cooling capacity of the air blowing device 6 is reduced. Since it does not change, the cooling performance of the electric component 5 can be secured.

By providing auxiliary louvers on the side surface in addition to the bottom surface of the fan, even if the seat 10 is adsorbed on the bottom surface of the bottom plate 3 and air cannot be sucked, the air blower 6 is provided with a vent hole provided as an auxiliary on the side surface of the bottom plate 3. As compared with the case where the seat 10 is not sucked by the bottom plate 3, intake air having a higher pressure is obtained, so that the cooling performance of the electric component can be secured. .
