The top frame 3 sufficiently withstands the heat from the heated object transmitted through the top plate 2 and is used as an external part. It is made of metal such as stainless steel or enameled steel plate that looks good and is resistant to corrosion.

  Furthermore, the inside is shown in the internal perspective view of the structure of the heating cooker in the 1st Embodiment of this invention of FIG. In FIG. 2, an operation unit and the like are disposed inside the top surface operation unit 4 formed on the top frame 3. Below the top plate 2, an induction heating coil 5 is provided in close proximity. The induction heating coil 5 is housed in a coil case 6 and is held at a predetermined position in the main body 1. The induction heating coil 5 is supplied with high-frequency power by the power circuit 7 and induction-heats the pan placed on the top plate 2. The induction heating coil 5 and the power supply circuit 7 are cooled by the ventilation of the cooling fan 8.

  A substantially box-shaped grill heating chamber 10 is disposed in the main body 1, and the grill heating chamber 10 has a grill function for placing the food and a saucer function for receiving oil from the food. The dish 11 is stored. A grill door 12 covering the opening of the grill heating chamber 10 is fitted to the grill pan 11, and the grill door 12 and the grill pan 11 slide back and forth in conjunction with each other, and the grill door 12 opens when the grill is used. The grill pan 11 is housed in the grill heating chamber 10.

  Here, FIG. 3 shows a cross-sectional view of the grill heating chamber 10 according to the first embodiment of the present invention. In the grill heating chamber 10, the grill pan 11 is placed on the bottom surface 13 of the grill heating chamber, and the food 14 is placed on the grill pan 11. Also, a lower heating means 15 is provided below the grill heating chamber bottom surface 13, and the heat of the lower heating means 15 is received by the grill heating chamber bottom surface 13, and the heat is transmitted to the grill pan 11 to be necessary for the cooked food 14. Cook with a sufficient amount of heat. By doing in this way, compared with the case where the conventional heating means is in a warehouse, since cooking or a carbide | carbonized_material adheres to a heating means and it does not ignite, it can apply sufficient heat to a grill pan. it can. Furthermore, when cleaning the grill heating chamber, there is no obstacle, so that the cleanability can be improved. In addition, in order to apply sufficient heat to the cooked food from above, the upper heating means 16 may be provided above the grill chamber.

  Next, the positional relationship between the grill pan 11 and the grill heating chamber bottom surface 13 during sliding in the present invention is shown in FIG.

  On the back side of the bottom surface of the grill pan 11, there are a grill pan non-sliding surface 17 that does not slide when being put in and out, and a grill pan sliding surface 18. The grill pan sliding surface 18 protrudes from the grill pan non-sliding surface 17 and is a part of the grill pan convex portion 19.
