Description

Technical Field

[0001] The utility model relates to the technical field of washing machines, and more particularly to a device for automatically adjusting water intake through pressure. Background Art

[0002] In modern families, washing machines are one of the most frequently used household appliances in daily life. Their convenience and efficiency have greatly improved people's quality of life. However, in actual use, washing machines cannot automatically adjust the water level according to the amount of clothes. This problem not only affects the washing effect, but also leads to waste of water resources and excessive consumption of electricity.

[0003] Traditional washing machines usually use fixed water level settings, that is, users need to manually select the washing mode according to their needs before starting the washing machine, corresponding to different water levels. Although this mode is simple and direct, it is often difficult to accurately match the actual needs of each wash. When there are fewer clothes, excessive water level will cause the clothes to float in the water, reducing friction and affecting the cleaning effect; when there are more clothes, the water level is too low and not all clothes can be fully soaked, which also reduces the cleaning efficiency. Inappropriate water level will also increase the workload of the washing machine, which will affect the service life of the washing machine. Utility Model Content

[0007] After water enters, when the pressure plate drops to the point where it engages with the inner cylinder, the controller controls the water inlet valve to stop water entry.
