Water level switch Adjusts water level according to the load size to prevent water waste when the laundry is light. Enables control of water volume for each cycle based on actual load, promoting efficient use of water resources and reducing unnecessary consumption. Pressure sensors Assist in regulating the water level to lower energy use during operation. Avoids using more electricity for unnecessarily water levels, contributing to longterm reductions in household electricity costs and supporting energysaving practices. Liquid level sensor Prevents overflow caused by water levels during operation. Stops water from leaking into the machine interior or onto the floor, reducing potential impact on the home environment and nearby facilities. Water level controller Links different water levels to corresponding washing program rhythms. Realtime monitoring of the water level ensures the program runs smoothly as set, avoiding interruptions or malfunctions due to abnormal water levels. Use scenarios Scenario 1: Quick wash for a small load. The system selects a lower water level to complete the cycle efficiently, saving both water and energy while delivering acceptable cleaning performance for lightweight clothes. Scenario 2: Delicate or mixed fabrics. Realtime water level monitoring maintains an appropriate level for gentle washing and effective rinsing, helping protect sensitive fabrics and improve overall cycle reliability. Scenario 3: Household energy and water savings. Across varying load sizes and daily laundry patterns, the sensors optimize water use and cycle timing, contributing to lower longterm utility costs and more consistent performance.
