Description

  The present invention relates to a heating cooker provided with an opening for intake or exhaust for cooling the inside of a main body on a top plate.

  Conventionally, this type of cooking device is provided with a top plate for placing a cooking pan, which is an object to be heated, at the top of the main body, and an intake port for sucking air for cooling the inside of the main body on the top plate rear side, An exhaust port for discharging the cooled air is provided, and an operation unit is provided on the front surface of the main body. The main body includes a heating unit, a control unit for controlling the heating unit, an air passage for cooling the heating unit and the control unit, and a cooling fan for supplying cooling air to the air passage.

  In addition, a ventilation cover is provided so as to cover the intake port and the exhaust port, and the ventilation cover is provided with a circular hole or a slit-shaped ventilation port.

  Then, the cooling air sucked into the main body from the air intake port through the ventilation port of the ventilation cover by the cooling fan cools the heating means, the control unit, etc., and then goes to the exhaust port. Is exhausted.

  Further, as shown in FIG. 9, the ventilation cover is detachable so that it can be easily cleaned because dust and oil in the air adhere to the surface due to intake and exhaust, and it becomes dirty due to scattering of the cooked food.

Further, the ventilation cover has an outer peripheral wall almost as shown in FIG. 10, and by fitting the inner surface of the outer peripheral wall with a positioning member made of a vibration-proof material provided on the top plate, Positioning in the front-rear and left-right directions with respect to the top plate is performed (see, for example, Patent Document 1 and Patent Document 2).
