Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION This invention relates to electrical appliances that require a relatively large output, such as induction cookers, electric cookers such as ovens, or irons.

BACKGROUND OF THE INVENTION Conventionally, when cooking hot pot dishes, etc. using a heating cooker, which is an example of this type of electric appliance, a load heat source such as a sake brewer is sometimes used in parallel with the cooking. many. In this case, for example, as shown in FIG. and were separately connected in parallel to a household AC 10o port power outlet 6.

Problems to be Solved by the Invention However, in such a conventional configuration, the power cord 4 of the load heat source 3 must be extended to the location of the household outlet 6. For this reason, the power cord 2 of the heating cooker body 1 and the power cord 4 of the other load heat source 3 are stretched out for a long time around the cooking area, which is extremely troublesome for the cooking operation, and also makes it difficult for the user to use the power cord. It was extremely dangerous for people to get their hands or feet caught in the power cord 4.

In view of the above problems, the present invention aims to reduce the number of power cords connected to household electrical outlets.

Means for Solving the Problems In order to achieve the above object, the electric appliance of the present invention is connected in parallel to the power supply section of the electric appliance main body having a load heat source section to provide an auxiliary power source for other equipment, and the above-mentioned The power supply main body is provided with a limiting circuit that controls the load heat source and makes the output of the power supply main body constant.

Effect: With the above configuration, other load heat sources can be connected to the auxiliary power supply section provided in the main body of the electric appliance, so there is no need to route the power cords of other load heat sources.

EXAMPLE Hereinafter, an example of the present invention will be explained in the case of an induction heating cooker with reference to FIGS. 1 and 2.

In FIG. 1, an attachment plug 7 serving as an auxiliary power source is provided on one side of the induction heating cooker main body e. Further, a power cord 8 that supplies power to the power supply section of the induction heating cooker is connected to a household outlet 5.

In the circuit configuration of this induction heating cooker, as shown in FIG. 2, an AC 100V power source 6 and an input current detection circuit 9 are connected via a power cord 8.

The detection signal of this input current detection circuit 9 is fed back to the load heat source section 1o, and a predetermined output of the device is set.

The attachment plug 7 is connected in parallel to the load heat source section 1o.

That is, even if other loads are connected to the plug 7, the output of the entire device is kept constant by the detection circuit 9.

When cooking hot pot dishes etc. with the induction heating cooker configured as above, the pot is placed on the induction heating cooker main body 6 and heated, and at the same time when cooking sake etc. teeth,
The power cord of a load heat source such as a sake brewer can be connected to the attachment plug 7 provided on the side surface of the induction cooking device main body 6. That is, current is supplied to the attachment plug 7 and the load heat source section 1o, which are auxiliary power sources, so that sake can be cooked in parallel with hotpot cooking.

At this time, the output of the main body power supply section is maintained at a constant level by the limiting circuit constituted by the input current detection circuit 9 and the load heat source section 1o, so there is no problem such as the output exceeding the output and the breaker etc. turning off.

Further, in this embodiment, the case where one attachment plug is provided has been described, but two or more attachment plugs may be provided, and the attachment plug is not placed on the side of the heating cooker main body, but on the top or bottom depending on the device. It goes without saying that the power cord may be provided at an optimal position for connecting the power cord.

In addition to the effects of the invention, as is clear from the examples, according to the present invention, other load heat sources can be connected to the auxiliary heat source provided in the main body, which reduces the number of power cords connected to household outlets and improves work efficiency. It is possible to prevent troublesomeness. Further, since the output of the main body power supply section is maintained at a constant level by the limiting circuit, it is possible to prevent the output from exceeding the output level and causing the breaker etc. to cut out.
