Preferably, the waterway plate is provided with a transition channel; one end of the transition channel is connected with the liquid inlet, and the other end of the transition channel is communicated with the liquid pumping port through a channel water pipe.
When the piston pump works, the detergent is pumped into the transition channel, then enters the piston pump, and then enters the public water path along the piston pump, so that a plurality of liquid storage boxes are conveniently arranged, and different types of detergents are pumped into the public water path.
Preferably, a public waterway is arranged on the waterway plate, and the public waterway is communicated with the washing drum; one end of the water draining channel is connected with the clearance cavity, and the other end of the water draining channel is connected with the washing barrel; the end of the water discharge channel connected with the clearance cavity is communicated with the outside atmosphere.
The water draining channel is connected with the washing tub, so that the water draining channel can reliably balance the negative pressure in the water inlet valve; the end of the drainage channel connected with the clearance cavity is communicated with the outside atmosphere, so that the pressure release effect of the drainage channel is better.
Compared with the prior art, the utility model has the following beneficial effects: the utility model sets up the anti-reflux assembly between inlet valve and waterway board, the anti-reflux assembly includes water inlet channel, water outlet channel and interval cavity, the said water inlet channel and water outlet channel are set up in the left and right sides of interval cavity; the inner diameter of the water inlet channel is gradually reduced along the water inlet direction, and the end of the water inlet channel with a larger opening is connected with a water inlet valve; when water enters the clearance cavity from the water inlet valve, the speed of the water flow is higher, the water flow enters the clearance cavity in a column shape and then enters the waterway plate along the clearance cavity, and thus the water inlet of the waterway plate is easier. Meanwhile, a water discharge channel is arranged at the bottom of the clearance cavity and used for balancing the negative pressure in the water inlet valve; when negative pressure is generated in the water inlet valve, water flows back along the water outlet channel, and the negative pressure in the water inlet valve is balanced due to the fact that the water outlet channel is communicated with the outside, the speed of backflow of the water flow is reduced, and therefore the water cannot flow back into the water inlet valve along the water inlet channel. Therefore, the utility model has good anti-reflux effect and simple and reliable structure.
