Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of water valves, and in particular relates to a switching valve, and also relates to a clothing processing device equipped with the switching valve. Background Art
[0002] Switching valves are often used inside and outside clothing processing equipment to achieve water circuit control with one water inlet and multiple water outlets. For example, in a user's home, generally only one water outlet is reserved at one location, and a nozzle is installed on the water outlet. When it is necessary to connect the washing machine to the reserved water outlet pipeline at this location, or to connect the washing machine to other water-using devices, a switching valve needs to be installed at the water outlet to meet the water needs of the washing machine and other water needs.
[0003] For example, when using a fully automatic washing machine, the drain pipe of the washing machine must be inserted into the drain, and the sewage is directly discharged into the drain, which reduces people's labor intensity. However, according to the current design of fully automatic washing machines, the washing water that could have been reused (accounting for about 70%-80% of the total water consumption) can only be discharged as wastewater. As people's awareness of saving water resources becomes stronger and stronger, some models are equipped with switching valves at the drain pipe to achieve water channel switching, so that the washing water with less dirtiness is discharged separately into the storage device for other purposes.
[0004] In addition, there are some models that, in order to improve the dissolution effect of detergent additives, set a switching valve downstream of the drain pump. The switching valve includes a drain port connected to the drain pipe and a circulation port connected to the outer drum. The power of the drain pump is used to return the detergent additives deposited at the bottom of the outer drum and in the drain pump to the outer drum through the internal circulation pipe, so that the detergent additives are fully dissolved.
[0005] Conventional switching valves, such as the Chinese utility model patent with application number CN201020236381.0, disclose a three-way drain valve for washing machines, which includes a body and a valve core, wherein the body has an inlet and two outlets, and the two outlets can be connected to the inlet; its working principle is: the valve core is rotatably connected to the body, and the two outlets are switched to connect to the inlet through the relative rotation between the valve core and the body. However, during use, the switching valve completely relies on the inner wall of the body to block the water path of the valve core, and if the water pressure is too high, water leakage is likely to occur.
[0006] Therefore, designing a switching valve that can achieve water channel switching and ensure high sealing performance has become a technical problem that needs to be solved urgently by technical personnel in this field.
[0007] In view of this, the present invention is proposed. Summary of the invention
