Document Type and Number:
WIPO Patent Application WO/2023/050543
Kind Code:
A1
Abstract:
The present invention provides an anti-siphon detergent dispensing system, comprising a water inlet valve, a water inlet channel, a liquid exchange cavity, a pump, and a detergent box A, and further comprising a water path switcher, wherein the outlet of the water inlet valve is connected to the water path switcher in series by means of the water inlet channel, and then is connected to the suction inlet of the pump and one interface end of the liquid exchange cavity in parallel; the other interface end of the liquid exchange cavity is connected to a valve A in series and then is communicated with a washing liquid inlet pipeline; the detergent box A is communicated with the liquid exchange cavity by means of a valve B; the first through port of the water path switcher is connected to the water inlet channel, a second through port is connected to the suction inlet of the pump and the liquid exchange cavity in parallel, and the inner cavity of the water path switcher is provided with a movable valve core capable of controlling the second through port to be opened or closed; and a liquid discharged from the outlet of the pump and the washing liquid inlet pipeline finally flows into a washing tub. The detergent dispensing system not only avoids the problem that water containing a detergent is sucked back to a water supply pipeline network due to a siphon phenomenon, but also ensures that a liquid pumping operation is normally performed.
