Claims

[Scope of Claim for Utility Model Registration] (1) For electric circuits provided to be connected to the power supply circuit of the first external device and the power supply circuit of the second external device, etc. that operate by receiving electric power, One of the plurality of terminals of the connector provided in the circuit is connected to the power supply circuit of the second external device, and
It is also connected to an excitation coil terminal of a transfer contact electromagnetic relay provided in the electric circuit,
The other terminal (hereinafter referred to as the fourth terminal) of the excitation coil of the transfer contact electromagnetic relay is connected to the power supply circuit of the second external device via a push button switch with a temporary closing mechanism provided in the electric circuit. , and another terminal of the connector is connected to a make contact of the transfer contact electromagnetic relay, and
The neutral contact and break contact of the transfer contact electromagnetic relay are control circuits constituted by electrical circuits that are separately connected to the power supply circuit of the second external device and the input terminal of the second external device, respectively. (2) the first external device connected to the electric circuit comprising a connector, a transfer contact electromagnetic relay, a push button switch with a temporary closing mechanism, etc. is a water pump driven by a motor;
The second external device is an electric washing machine (hereinafter referred to as a washing machine)
A tap water supply solenoid valve (hereinafter referred to as a solenoid valve) provided in the interior of the washing machine, which circuit is closed for a certain period of time by pressing the push button switch with a temporary closing mechanism when a washing machine equipped with the solenoid valve starts washing. As a result, the transfer contact electromagnetic relay is energized and operated for a certain period of time, and its neutral terminal and break contact are opened to stop power supply to the electromagnetic valve, thereby stopping the supply of tap water. At the same time, the make contact and the neutral terminal are closed, and power is supplied to the power supply circuit of the water supply pump through the connector, and the water supply pump is driven to supply water other than tap water to the water tank inside the washing machine. If water is supplied until the water level detector detects the appropriate water level and the push button switch with temporary closing mechanism is closed for a certain period of time, if the water level detector does not detect the appropriate water level, the push button switch with temporary closing mechanism After a period of time, the circuit is opened and the transfer contact electromagnetic relay is demagnetized, and its neutral terminal and make contact are opened, and the power supply to the water supply pump is stopped, so that the water supply pump is stopped. At the same time, the break contact and the neutral contact are closed, power is supplied to the solenoid valve, and tap water is supplied until a water level detector installed in the washing machine detects an appropriate water level. control circuit.
