Here, when heating the magnetic material pot 8 by energizing,
In order to prevent the temperature of the heating coil 2, frequency converter 3, etc. from rising, the cooling device 4 is activated, and the bottom surface 1 of the housing 1 is heated.
A cooling system is configured in which cooling air 9 is sucked in through the intake hole 6 of the housing 1, circulates inside the housing 1, and is discharged as exhaust air 10 through the exhaust hole 7 provided on the bottom surface 1a or rear surface 1b of the housing 1. However, when the exhaust hole 7 is formed only on the rear surface 1b of the housing 1 as shown in FIG. 1, all the exhaust gas is exhausted from the exhaust hole 7,
When the user is located on the rear surface 1b side of the housing 1,
The aforementioned exhaust air hits the user, causing discomfort to the user. Alternatively, as shown in FIG. 2, if the exhaust hole 7 is formed only on the bottom surface 1a of the casing 1, the above-mentioned discomfort to the user can be avoided, but there may be a table cloth, jacket 11, etc. on the table. , they become wrinkled as shown in Figure 3.
As a result, when the exhaust hole 7 is blocked, there is a problem in that the cooling performance drops to the bottom, causing a malfunction.

Composition of the Invention In order to achieve the above object, the tabletop electromagnetic induction heating cooker of the present invention is provided with an exhaust hole extending from the bottom of the casing that touches the rear surface at a substantially right angle. Since the exhaust hole is larger than the exhaust hole on the rear side, most of the exhaust gas is exhausted from the exhaust hole on the bottom side, reducing the amount of exhaust air compared to the rear side, reducing the discomfort of the exhaust hitting the user. Also, when used on top of a tablecloth, etc., even if the tablecloth gets wrinkled and blocks the exhaust holes on the bottom side, the exhaust holes on the rear side will ensure the minimum necessary cooling performance. It is effective.

The operation of the above configuration will be explained below.
When electricity is supplied, an eddy current is generated between the heating coil 15 and the magnetic pot 20, and the heating coil 15 is heated by Joule heat. At this time, the cooling device 17 is operated to cool down the power components used in the frequency converter 16 to prevent them from generating heat. At this time, the bottom surface 14 of the lower case 14
Cooling air 21 sucked in from the intake hole 18 provided in the lower case 14 circulates inside the housing, cools power components such as the frequency converter 16, and is discharged as exhaust 22 from the exhaust hole 19 provided in the lower case 14. be done. Here, the exhaust hole 19 is formed so that the exhaust hole A19a provided on the bottom surface 14a of the lower case 14 is larger than the exhaust hole B19b provided on the rear surface 14b. The amount is greater than the amount of exhaust from the exhaust hole B19b on the rear surface 14b. In other words, the exhaust hole B1 on the rear surface 14b
Since the exhaust volume from 9b can be reduced compared to the conventional one, the exhaust air 22 is less likely to hit the user, thereby reducing the user's discomfort. When the lower case 14 is used as
Since it is in contact with a at a substantially right angle, the bottom surface 1 of the lower case 14
Even if the exhaust hole A19a of the rear surface 14b is blocked by wrinkles in a table cloth, etc., the exhaust hole B19b of the rear surface 14b, which stands up approximately at right angles to the bottom surface, will not be blocked. Since a limited amount of exhaust gas is ensured, it is possible to prevent failure of internal parts of the electromagnetic induction cooking device due to deterioration of cooling performance.
