The first power outlet and the first power outlet are provided with another second power outlet that does not share a power circuit in the one storage room.

According to this invention comprised as mentioned above, since the power supply outlet of the 2 power supply system which does not share a power circuit in one storage room is provided, the cooking appliance with big power consumption can be operated simultaneously. Therefore, for example, a cooker with high power consumption such as an electric rice cooker and an oven toaster can be used at the same time, improving usability.
In addition, the electric cooker in this invention means the electric appliance mainly used in a kitchen, and includes water heaters, such as an electric kettle.

  Another feature of the present invention is that one of the first power outlet and the second power outlet is a one-port type having one set of plug insertion ports, and the other has a plurality of sets of plug insertion ports. It is to be a multi-mouth type.

According to this, for a high-priority electric cooker that does not want to be cut off during cooking, a power plug is connected so that power is supplied from a single-type power outlet, thereby providing stable power supply. Can receive.
In addition, an electric cooker that does not consume much power can be used without replacing the power plug by connecting a power plug so that power is supplied from a multi-type power outlet. In this case, even if it is used at the same time as an electric cooker that is fed from a single-type power outlet, the power is not shut off, and it is very convenient.
Further, since different types of power outlets are used, the power outlets of the two power supply systems can be easily identified and used properly.

  Another feature of the present invention resides in that the first power outlet and the second power outlet are arranged side by side.

  According to the present invention, two power outlets can be put together in one place and the layout can be made clear. Even if they are combined in one place in this way, since different types of power outlets are used, they can be easily identified and used properly. Moreover, the handling of the power cord of the electric cooker is not complicated.
