[0063] In many fields, there is the problem of how to provide power to a rotating part that can rotate on its own. As wireless charging technology gradually matures, this problem has been well solved. For example, in the field of household appliances, washing machines usually need to be equipped with some power loads on the inner drum to monitor the movement state of the inner drum or the clothes in the inner drum, such as temperature sensors, humidity sensors, etc. Since the power load will rotate with the inner drum, the current power supply method is to set a power supply device on the outer side of the inner drum and use wireless charging technology to transmit power to the power load. However, the current power supply method has a large energy waste problem during power transmission.

[0064] Based on this, the present application embodiment provides a power supply method, referring to Figure 1The flow chart of the power supply method shown is used to provide electric energy to a load on a rotating part capable of self-rotation, wherein a power supply part is provided on the outer peripheral side of the rotating part, a power transmission part electrically connected to the load is provided on the rotating part, the power supply part is used to supply electric energy to the power transmission part, and the power transmission part is used to transmit electric energy to the load, when the rotating part rotates, the load and the power transmission part rotate with the rotating part, and the power supply part does not rotate with the rotating part, and the method includes the following processing procedures.

In addition, since which power supply segment is needed to power the power transmission component, which power supply segment is controlled, it is not easy for the power supply segment to be in a power supply state for a long time, which is beneficial to improving the life of the power supply segment, thereby improving the life of the power supply component.

[0114] Alternatively, the degree of power supply to be provided is determined according to the ratio of the running time to the total running time, wherein the larger the ratio is, the lower the degree of power supply to be provided is.

[0115] The embodiment of the present application further provides a clothes processing device, the clothes processing device comprising a processing drum, and the processing drum is provided with an electrical component;

[0116] The clothes processing device adopts the above-mentioned power supply method to supply power to the electrical components.

[0117] For ease of understanding, the following specific scenario is used to illustrate the power supply method provided in the embodiment of the present application.

[0118] Currently, there are few washing machines on the market that use wireless charging technology, and the control scheme for wireless charging technology in washing machines is not very mature. The corresponding technical scheme is being vigorously studied in the field of washing machines. However, there is a great waste of electricity during transmission, lack of charging area planning, and power waste is accompanied by circuit heating and shortened component life.

[0119] Based on this, this embodiment accurately controls the operation of the wireless charging power supply device during the start-up phase of low-voltage loads such as temperature sensors in different washing processes of the washing machine, divides the area inside the barrel into several rechargeable areas, and controls the power supply devices in different areas according to the power receiving device to control the power supply phase. When some power supply devices are turned on, the power supply devices in other areas will not supply power, thereby accurately controlling the operation of the wireless power supply device.

[0120] like Figure 3-7 As shown, 1. A wireless charging device is set in the washing machine, and the device includes a power supply device denoted as PS and a power receiving device denoted as PR, which is used to supply power to the rear-end low-voltage load, wherein the power receiving device contains a rechargeable and dischargeable battery pack denoted as B, and the low-voltage load may include a temperature sensor denoted as LVL. The low-voltage load-LVL referred to here is installed on the inner wall of the inner drum and can rotate with the inner drum.

[0121] 2. Set the rechargeable and dischargeable battery pack-B. The battery capacity is divided into four stages, namely safe power, low power, normal power and sufficient power. Among them, safe power < low power < normal power < sufficient power. When the safe power is reached, the battery stops discharging to protect the life of the built-in battery of the washing machine. The charge and discharge capacity of B is controlled according to the different power consumption of different low-voltage loads required in different washing stages. B plays a role in providing battery life for LVL when PS and PR fail. When PR supplies power to LVL, B does not supply power to LVL. The discharge working state of B is controlled by the host.

[0122] 3. The inner drum space of the washing machine is divided into four parts, namely the first, second, third and fourth quadrants. In order to ensure the controllability of the power supply period in the drum space, the rechargeable area is divided into the outer drum area corresponding to the first, second, third and fourth quadrants and the PS is arranged. The PS does not rotate with the inner drum. When the PR reaches the rechargeable area, such as the first quadrant, it can start charging. At this time, the power supply devices in the other areas do not supply power. When the PR enters the second quadrant from the first quadrant, the power supply device in the second quadrant supplies power, and the other power supply devices do not supply power. Low-voltage loads such as temperature sensors will only start working in the corresponding washing stage. This solution controls low-voltage loads such as temperature sensors to control the power supply device not to supply power during the washing stage that does not need to be turned on, that is, the PS is turned on and off according to the washing process of the whole machine and the position of the PR. When PR receives power, it supplies power to B and LVL.

[0123] 4. In this control method, a first control process is set to control the working state of the wireless charging device according to the washing process. When the washing machine is in working state, the host detects the washing stage the washing machine is currently in. According to the different low-voltage loads required to be turned on in different washing stages such as water inlet and outlet, water heating, and drying, for example, the temperature sensor is turned on in the drying stage. If the washing process is detected to be in a non-opening stage, the PS action of turning on is not performed, and the whole machine washing process is returned to be detected; when the washing process is detected to be in the drying stage, the temperature sensor is needed, and when it is determined that the wireless charging device is in a stage that can be turned on, the PS action of turning on is performed.

[0124] After the power supply device-PS is turned on, the power receiving device-PR is detected to see if it is in the chargeable area. If PR is in the chargeable area, such as the first quadrant power supply area, the power supply device in the corresponding area of ​​the first quadrant is turned on, and the power supply devices in other areas are not turned on. When PR turns on the power supply device area, it starts to collect electricity to supply power to B and LVL, and LVL starts working after power is turned on; if PR is not in the chargeable area, such as the second, third, and fourth quadrants, the motor rotates at the set speed, driving the inner cylinder to rotate and adjust the PR position accordingly. The motor can rotate clockwise or counterclockwise according to the preset process, and then the next action is executed.

[0125] The next action is to detect whether PR is in the rechargeable area. If PR is in the rechargeable area, for example, the second quadrant power supply area, the power supply device in the corresponding area of ​​the second quadrant is turned on, and the power supply devices in other areas are not turned on. PR starts to collect electricity to supply power to B and LVL, and LVL starts working after power is turned on; if PR is not in the rechargeable area, it returns to the motor action link, and so on.

[0126] like Figure 7 As shown, the control realizes the power supply and power off state conversion of the wireless power supply device in the corresponding area of ​​different quadrants. The IC end is controlled by the washing machine host, power supply 1 is connected to the power supply of the whole machine, and power supply 2 is connected to the power supply of the power supply device PS to power the PS. When the IC end outputs a high signal, the NPN transistor is turned on, and then the PNP transistor is turned on, and the power supply 2 obtains power, that is, the PS is powered; when the IC end outputs a low signal, the NPN transistor is turned off, and then the PNP transistor is turned off, and the power supply 2 cannot obtain power, that is, the PS is powered off. In this way, the power supply devices in different quadrants are controlled to be turned on and off.

[0127] 5. In this control method, a second control process is set. When the wireless charging device fails, it cannot supply power to the rear-end LVL. At this time, the rechargeable and dischargeable battery pack-B supplies power to the LVL. When the power receiving device-PR receives power, the washing stage of the whole machine is detected. The entire washing stage of the whole machine is divided into two stages, namely the first half and the second half, and the second half is after the first half. When the whole machine is in the first half of the washing process, the low-voltage load-LVL consumes a lot of power to complete the entire stage; when the whole machine is in the second half of the washing process, the subsequent stage LVL consumes less power than the first half of the washing process of the whole machine. The charge and discharge state of the rechargeable and dischargeable battery pack-B is controlled accordingly to achieve reasonable charging and discharging and extend the life of B. After detecting the washing stage of the whole machine, execute the next step.

[0128] When the detection washing stage is in the first half, start to detect the remaining power of B. If B is in the safe power range, stop discharging, execute the fast charging command, and then return to the detection washing stage; if B is in the low power range, you can execute the discharge command, and execute the fast charging command at the same time, and then return to the detection washing stage; if B is in the normal power range, execute the slow charging action, and execute the discharge command at the same time, and then return to the detection washing stage; if B is in the sufficient power range, execute the stop charging command, and execute the discharge command at the same time, and then return to the detection washing stage.

[0129] When the detection washing stage is in the second half, start to detect the remaining power of B.
