Description

Technical Field

[0001] The utility model belongs to the technical field of washing machine water inlet systems, in particular to a single-valve multi-waterway controlled automatic delivery system. Background Art

[0002] At present, the automatic dispensing system of washing machines generally adopts accessories including water tank components, dispenser box components and washing machine valves. The water tank component also includes a water tank, a water tank upper cover, a water tank lower cover, etc. The water tank upper cover and the water tank lower cover form a water path through processes such as hot plate welding. The washing machine valve is connected to the water tank assembly through a hose, and the liquid is transmitted by the water path on the assembly. Each washing machine valve generally controls the flushing of one water path. The more functions a washing machine has, the more water paths there will be, the corresponding washing machine valves will also increase, and the cost of the product will also increase greatly. Although there are also cases where two water paths share one washing machine valve, cross-water leakage of different rinse agents will occur, which is very likely to cause overflow, water leakage, scale precipitation and other problems, resulting in a poor user experience.
