Since there can only be one load working in this circuit, it is not suitable for a clothes treatment device containing multiple clothes treatment units.

For example, a dry cleaning machine contains a washing unit and a drying unit; for example, a double drum washing machine that can sort and wash clothes contains two washing units and each washing unit can also be dried. Since the laundry treatment equipment contains multiple laundry treatment units, more loads are connected to the circuit of the laundry treatment equipment, and the more loads include some high-power loads, such as drying and/or heating of care clothes Device. In order to ensure that the total power in the circuit of the clothing treatment equipment does not exceed the total load power of the power cord, it is necessary to control the type and number of loads that can be connected to the circuit each time.

The present invention takes into account the problem of ensuring the total power in the circuit of the clothing treatment equipment, and proposes to design the circuit of the clothing treatment equipment so that the circuit of the clothing treatment equipment is connected to at most one high-power load and one low-power load at a time, thereby ensuring the connection The total power of the circuit is lower than the total load power of the power cord, thereby ensuring the stability of the circuit of the laundry treatment device.

The high-power load described in the present invention is a device whose power exceeds half of the total load power of the circuit, and a low-power load is a device whose power is generally lower than the total load power of the circuit.

Based on the above circuit design ideas, the present invention proposes different circuit connection forms in the following three embodiments to meet actual needs. In addition, the connection in the circuit described in the present invention refers to the flow of current, and the connection to a certain load refers to that a certain load has current flowing and can be operated. The positions of the live wire end and the neutral wire end in each type of circuit connection diagram can be interchanged. In the circuit connection diagram, the A contact and the B contact of each single-pole double-throw switch can be interchanged in pairs. And the thermal power terminal in the circuit is the terminal directly connected to the power supply terminal, and the neutral terminal is the terminal connected to the ground wire.

In fact, more loads can be connected in parallel according to the circuit connection modes in FIGS. 1-4.

As shown in Figure 1-4, in the third branch 5 of the first circuit 1, the A contact of the single-pole double-throw switch K12 is connected to the third high-power load first, and then to the single-pole single-throw switch K31; In the sixth branch 8, the A contact of the single-pole double-throw switch K22 is connected to the third low-power load first, and then the single-pole single-throw switch K41 is connected.
