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.

As shown in fig. 1 to 5, the second circuit 2 is specifically arranged in the following manner: the second circuit 2 is connected with a plurality of branches in parallel in sequence, and each branch is provided with a low-power load and a single-pole single-throw switch for controlling the on-off of the branch; the outputs of all low power loads are connected to a first common node 3 of the second circuit 2 and the inputs of all low power loads are connected to a second common node 4 of the second circuit 2, the first circuit 1 being connected to the first common node 3 and the second common node 4, respectively, such that the first circuit 1 and the second circuit 2 are connected. A larger number of low power loads can be connected in parallel in the second circuit 2, as shown in fig. 1-5, in this embodiment, two low power loads are connected in parallel for example, and actually, a larger number of low power loads can also be connected in parallel. As shown in fig. 1-5, the first circuit 1 places different high-power loads on different branches, and then controls the branches to be connected, i.e. controls the high-power loads to be connected, by arranging a single-pole double-throw switch in the first circuit 1.

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. The difference between fig. 2 and 3 is whether the single-pole single-throw switch K31 and the single-pole single-throw switch K41 are provided on the same drying plate.

As shown in fig. 6 to 8, the present embodiment provides a clothes treating apparatus based on embodiment 1, and the circuit design of the clothes treating apparatus of the present embodiment also enables the clothes treating apparatus to control any one high-power load to be communicated alone or to be communicated with any one low-power load at the same time, but the present embodiment provides a different form of circuit connection from embodiment 1.

As shown in fig. 6, which is a schematic diagram of a circuit principle of this embodiment, two single-pole double-throw switches are arranged in a first circuit 1 of this embodiment, and the two single-pole double-throw switches are connected in series, two branches are led out through the two single-pole double-throw switches, a high-power load is arranged on each branch, and on/off of the high-power load of the branch in which the single-pole double-throw switch is located is controlled. Specifically, the live wire end of the first circuit 1 is connected with a fixed point of a single-pole double-throw switch K11, a B contact of the single-pole double-throw switch K11 is connected with the first branch 5, an a contact of the single-pole double-throw switch K11 is connected with a fixed point of a single-pole double-throw switch K21, a B contact of the single-pole double-throw switch K21 is connected with the second branch 6, and an a contact of the single-pole double-throw switch K21 is connected with the first common node 3 of the second circuit 2; the output end of the first high-power load of the first branch 5 and the output end of the second high-power load of the second branch 6 are connected in parallel to the same path, and the same path and the second circuit 2 are sequentially connected with the second common node 4 and the zero line end. That is, the first high power load or the second high power load is connected to the circuit by the series connection of the two single-pole double-throw switches in the first circuit 1. The single-pole double-throw switches are connected in series with each other, so that current flows into the branch where the single-pole double-throw switch is located or flows to the next adjacent single-pole double-throw switch.

K11 is connected with the contact A, K21 is connected with the contact B, the second high-power load works, and the first high-power load, the first low-power load and the second low-power load cannot work. The embodiment provides a scheme for ensuring that the clothes treatment equipment controls any one high-power load to be communicated independently or any one low-power load to be communicated simultaneously on the basis of the embodiment 1, and a specific circuit connection form can be selected according to requirements during actual use.

I.e. whether each high power load in the circuit can be connected depends on whether the single pole, single throw switch in the branch of the second circuit 2 to which the high power load is connected in addition to the single pole, double throw switch. The arrangement is such that each high power load is commonly controlled by a single pole double throw switch and a single pole single throw switch.

As shown in fig. 11, the first branch 5 is connected to the branch where the second low-power load is located, so that the single-pole single-throw switch K41 can determine the on/off of the first high-power load; the first branch 6 is connected with the branch where the first low-power load is located, so that the single-pole single-throw switch dry K31 can determine the on-off of the second high-power load.
