理由により望ましい。Conventional Structure and Problems Conventionally, in this type of rice cooker, a heat retention on/off switch is often provided with a switch that turns on/off all electric currents. In order to turn on and off all the currents, a large switch is required, which is very disadvantageous in terms of cost and design space, and it is preferable to turn on and off only the heat-retaining current for the reasons mentioned above.

スペースの面で、非常に不利であつた。 However, as heater configurations became more complex, such as with additional heating functions, it became extremely difficult to turn on and off only the heat-retaining current due to factors such as lamp displays.
Conventionally, in a jar rice cooker with additional cooking, as shown in Fig. 1, an AC power supply 1, a current OFF switch 2, the ON side of the rice cooking switch 3, and a rice cooking heater 4 are connected in series, and the rice cooking switch 3 and the rice cooking heater are connected in series. A heat retention heater 5 and an additional cooking timer 6 were connected in parallel to the series circuit of 4, and the current OFF switch 2 was also used to turn off the heat retention. For this reason, the current OFF switch 2 is required to have a large capacity since current also flows during rice cooking, which increases cost and
This was a huge disadvantage in terms of space.
