Description

  The present invention relates to a heating cooker, and in particular, water that leaks out of a heating chamber due to water vapor generated from an object to be heated by heating cooking or water vapor generated by a steam generating means adheres to a door or a rear wall of a heating chamber facing the door. This relates to the construction of the drainage channel.

  In recent years, cooking devices have the function of heating high-temperature steam by means of steam generating means to heat the object to be heated, in addition to high-frequency heating such as microwave ovens and electric heating such as ovens and grills. Is increasing.

  Water vapor generated from the object heated in the heating chamber of the heating cooker, or water generated by the steam generating means adheres to the door or the rear wall of the heating chamber facing the door. It must be prevented from dripping and adhering to the electrical parts or dripping onto the kitchen floor. Therefore, in the conventional cooking device, it adheres to the rear wall of the heating chamber facing the door. The water dripping outside the heating chamber is received by a water receiving partition (see, for example, Patent Document 1).

  FIG. 3 shows a conventional heating cooker described in Patent Document 1. As shown in FIG. As shown in FIG. 3, the rear wall surface 1 of the heating chamber is connected to the evaporating dish 2 that is a part of the steam generating portion by caulking or spot welding. The water adhering to the heating chamber rear wall surface 1 is guided downward by the capillary phenomenon of the contact surface between the heating chamber rear wall surface 1 and the evaporating dish 2 and leaks out of the heating chamber. The water leaking out of the heating chamber is structured to stay in the water storage section 4 of the water receiving partition section 3.

  Moreover, in order to prevent the water adhering to the heating chamber surface of a door dripping on the floor surface of a kitchen, there also exists a heating cooker provided with the water saucer below the door (for example, refer patent document 2).
