  • Suction and exhaust system of a heat cooking apparatus
    Patent number: 4899028
    Abstract: According to the electromagnetic cooking apparatus of the present invention, a ventilation hole, through which air after cooling an interior compartment of the main casing of the cooking apparatus is exhausted, communicates with the exhaust passage of the exhaust device so that the suction force of a fan member of the exhaust device is also utilized for exhausting the cooling air, thereby contributing to an improvement in the exhausting efficiency of the cooking apparatus, and the fact that a relatively small fan motor for the cooling device can be used. Consequently the cooling device can be small, which in turn enables the size of the electromagnetic cooking apparatus itself to be relatively small.
