Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following describes the defect management modes in the embodiments in detail with reference to the drawings in the embodiments of the present invention.

The current laundry treatment apparatuses are often provided with more functions, such as a washing and drying machine and a washing machine with a laundry care function, which results in that the laundry treatment apparatuses often have a plurality of high power loads, such as a plurality of heaters inside the laundry treatment apparatuses. In addition, there are many laundry treatment apparatuses including a plurality of laundry treatment units, such as a dual-drum washing machine, and many high-power loads are disposed inside such laundry treatment apparatuses. In order to avoid the situation that a plurality of high-power loads work simultaneously when the clothes treatment equipment works, so that the total power of the circuit is higher than the total load power of the power line. According to the invention, through the circuit design of the clothes treatment equipment, the circuit of the clothes treatment equipment is independently communicated with any one high-power load or simultaneously communicated with any one low-power load, so that the total power connected into the circuit is lower than the total load power of the power line, and the circuit stability of the clothes treatment equipment is further ensured. The high-power load is a device with power exceeding half of the total load power of the circuit, and the low-power load is a device with power lower than the total load power of the circuit. In addition, the connection in the circuit in the invention means that current flows, and the connection with a certain load means that a certain load can run and work when current flows. The positions of the live wire end and the zero wire end in each form of circuit connection diagram can be interchanged, and the contact A and the contact B of each single-pole double-throw switch in the circuit connection diagram can be interchanged in pairs. And the thermal power end in the circuit is the end directly connected with the power supply end, and the zero line end is the end connected with the grounding wire. All loads connected in a circuit have an input and an output in the direction of current flow. The invention provides the following 3 embodiments according to the circuit design thought, and each embodiment provides different circuit connection forms to meet the actual requirement.

Example 1

As shown in fig. 1 to 5, the present embodiment provides a laundry treating apparatus in which a plurality of high power loads and a plurality of low power loads are incorporated as described above. A plurality of high-power loads are connected to a first circuit 1 in a circuit of the clothes treatment equipment, a plurality of low-power loads are connected to a second circuit 2 in parallel, the first circuit 1 and the second circuit 2 are connected, and a control device is arranged in the first circuit 1 and the second circuit 2 and controls any one high-power load to be communicated with each other independently or simultaneously. That is, the clothes treating apparatus is connected to one high power load alone or any two low power loads simultaneously through the design of the circuit arrangement and control device in the first circuit 1 and the second circuit 2. When only one high-power load is communicated in the circuit or a plurality of low-power loads are communicated in the circuit at the same time, the total load power of the circuit is smaller than that of the power line due to the fact that the total power of the circuit loads is smaller under the two conditions, and therefore the stability of the circuit is guaranteed.

As shown in fig. 1-5, the control device includes a single pole, single throw switch, a single pole, double throw switch. A single-pole double-throw switch is arranged in the first circuit 1 to control the current to flow to the first circuit 1 or the second circuit 2; and controls at most one high-power load to be connected to the first circuit 1 at a time when current flows to the first circuit 1. Namely, the single-pole double-throw switch in the first circuit controls the clothes treatment equipment to be communicated with the first circuit only or the second circuit only; and when current flows into the first circuit, the first circuit is controlled to control any one high-power load to be connected. A single-pole single-throw switch is arranged in the second circuit 2 to control the on-off of each low-power load in the second circuit 2. The arrangement is such that when the current of the laundry treating apparatus flows into the first circuit 1, the second circuit 2 is not switched on, and the laundry treating apparatus is only switched on one high power load. Or when the current of the laundry treating apparatus flows into the second circuit 2, the first circuit 1 is not turned on, and the laundry treating apparatus is only simultaneously connected to any number of low power loads. Therefore, the total power of the circuit can be ensured to be smaller than the total load power of the power line, and the stability of the circuit is further ensured.

Namely, through the setting of the single-pole double-throw switches K11 and K21, when the single-pole double-throw switch K11 is connected with the contact B and the single-pole double-throw switch K21 is connected with the contact a, the first high-power load of the first branch 5 is connected into the circuit; when K11 is connected to the a contact, current flows into the second circuit 2, and the laundry treating apparatus can only be connected to a low power load; when K21 is connected to the B contact, the second high power load is switched into the circuit. The A, B contacts of the single pole double throw switch of the first circuit 1 of this embodiment are interchangeable.

As shown in fig. 2 to 3, the present embodiment also shows two specific circuit connection forms provided according to the schematic diagram of the first form.

As shown in fig. 7 to 8, two specific circuit connection forms are shown in the schematic diagram according to the present embodiment.
