(Embodiment 1)
FIG. 1 illustrates an induction heating cooker as the cooking device according to the first embodiment of the present invention.

  As shown in FIG. 1, the main body includes an outer shell 11 constituting the main body, a ceramic top plate 12 provided on the upper surface of the main body, and a heating coil for heating an object to be heated placed on the top plate 12. There are a heating unit 13, an output control unit 14 for controlling the output of the heating unit 13, a cooling device 15 having a fan configuration for supplying cooling air to the heating unit 13 and the output control unit 14, and a roaster unit 16 provided in the main body. Is provided.

  The roaster unit 16 is provided with a heating chamber 18 having an opening 17 on the front surface of the main body for heating an object to be heated and a door 19 for opening and closing the opening 17. A pair of rails 20 having a sliding function are provided outside the heating chamber 18, and a rail opening 21 is provided on the front wall surface of the heating chamber 18 in order to slide the rails 20. The left and right ends are connected to each other by a connecting member 22.

  An elastic body 23 is provided on the heating chamber side of the connecting member 22, and the rail opening 21 is closed by the elastic body 23.

  About the cooking-by-heating machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When a user puts a cooked item (second object to be heated) in the heating chamber 18 and performs cooking, the temperature in the heating chamber 18 rises. Part of this heat is transmitted to the entire heating chamber 18 and the periphery of the roaster unit 16, and the temperature inside the main body rises. Since the cooling device 15 generates a blowing pressure, the pressure inside the main body is increased, and the cooling air is exhausted through any openings or ventilation paths if there are any.

  When the heating unit 13 and the output control unit 14 are operated to inductively heat the pan (first object to be heated) on the top plate 12 while using the roaster unit 16, the heating unit 13 and the output control unit 14 are operated. Therefore, high cooling performance is required. In particular, when induction heating is used at a high heating power, higher cooling performance is required than when only the roaster section 16 is used.

  However, if the air volume of the cooling air is increased to ensure cooling performance, the pressure inside the main body increases, the pressure difference between the inside and outside of the main body increases, and the cooling air easily enters the gap inside the main body. Moreover, if there is the rail opening 21, it becomes easy to exhaust outside.

In the roaster unit 16, when a rail 20 having a sliding function is provided outside the heating chamber 18 so that the tray can be pulled out smoothly, the rail 20 is slid on the front wall surface of the heating chamber 18 to slide the rail 20. An opening 21 is provided. When the cooling device 15 is activated to generate the blowing pressure, the pressure inside the main body is increased, and the cooling air is exhausted from the rail opening 21 through the rail 20 portion. The heating chamber 18 has an opening 17 on the front surface, and when cooling air is exhausted from the rail opening 21, the heating chamber 18 flows into the heating chamber 18 from the opening 17. When the cooling air flows into the heating chamber 18, the temperature in the heating chamber 18 is lowered and an appropriate temperature for cooking cannot be maintained, so that it is difficult to obtain desired cooking performance.

  Therefore, in the present embodiment, an elastic body 23 is provided on the heating chamber 18 side of the connecting member 22, and when the rail 20 is pulled by the elastic body 23, the rail opening 21 is closed, and the cooling air is supplied to the rail during cooking. Since it is configured to suppress blowing out from the opening 21 and flowing into the heating chamber 18, the inside of the roaster heating chamber 18 is not cooled by the inflow of cooling air, and is maintained at an appropriate temperature, and at the same time It is possible to provide a cooking device that can secure a natural air flow and improve the usability of the roaster. Therefore, even when the cooling device 15 is operated when the roaster unit 16 is used, the cooling air does not blow out from the rail opening 21, so that the inside of the roaster cabinet is not cooled by the inflow of the cooling air, and the temperature is adjusted to an appropriate temperature. Can keep.
