Further, the frame plate 12 may be formed with a depression or a groove for receiving a protrusion 21d or a rib provided on the peripheral portion 21b on the bottom surface of the pot 21. Thereby, the pan 21 can be positioned on the frame plate 12 in a state where the annular gap SP is uniform.
[0028]
FIG. 5 is a partial cross-sectional view showing a second modified example in which the pot 21 is mounted on the frame plate 12 placed on the main body case 11. In this modification, a substantially annular rib (hereinafter, referred to as an annular rib) 21 e is provided between the peripheral portion 21 b and the inner portion 21 c on the bottom surface of the cooking pot 21 so as to receive radiant heat from the heater 16. ing. According to such a configuration, since the radiant heat from the heater 16 toward the frame plate 12 is received by the annular rib 21e and used for heating the deep pan 21, the heating efficiency can be increased.
[0029]
As can be seen from FIGS. 3B and 3C, it is necessary to cut out the annular rib 21e only so that the drawn portion of the heater 16 does not interfere with the annular rib 21e. Alternatively, the drawer of the heater 16 may be bent downward so as not to interfere with the annular rib 21e. FIG. 5 shows an example in which the second modification is combined with the first modification (projection 21d), but the second modification may be implemented alone.
[0030]
FIG. 6 is a partial cross-sectional view showing a third modified example in which the pot 21 is mounted on the frame plate 12 placed on the main body case 11. In this modification, a heat insulating material 12c and a heat storage effect material 12d are provided at a contact portion of the frame plate 12 with the deep pan 21. By doing so, the conduction heat from the heated deep pan 21 to the frame plate 12 is further suppressed, so that the heating efficiency can be increased. Further, the action of the heat storage effect material 12d makes it difficult for the deep pan 21 to cool even after the power supply to the heater 16 is stopped. Note that only one of the heat insulating material 12c and the heat storage effect material 12d may be provided. It should be noted that a certain effect can be obtained only by thickly coating the frame plate 12 with a paint mixed with a filler having a heat storage effect or a heat insulating effect.
