[0057] The delivery device provided in the embodiment of the present application is applied to a clothes processing device, and the clothes processing device includes a washing drum 8, see Figures 1 to 3The dispensing device includes a water inlet valve 1, a detergent box 2, a dispensing pump 3 and a spray pipe 4. The detergent box 2 is provided with a liquid storage chamber 21; the dispensing pump 3 includes a liquid pumping end 31 and a liquid outlet 32 ​​connected to each other, and the liquid pumping end 31 is connected to the liquid storage chamber 21; the spray pipe 4 includes at least two liquid inlets 411 and a liquid outlet connected to each other, and the at least two liquid inlets 411 are respectively connected to the liquid outlet 32 ​​and the water inlet valve 1, and the liquid outlet is used to discharge liquid to the washing tub 8.

[0058] The dispensing device provided in the embodiment of the present application pumps the detergent in the liquid storage chamber 21 of the detergent box 2 into the spray pipe 4 through the dispensing pump 3. At the same time, the water inlet valve 1 also directly feeds water into the spray pipe 4. When detergent needs to be dispensed into the washing tub 8, the dispensing pump 3 and the water inlet valve 1 are opened at the same time to dispense detergent and water into the spray pipe 4. The detergent in the spray pipe 4 is dissolved by water and flows into the washing tub 8, thereby preventing the water inlet valve 1 from feeding water into the detergent box 2 and causing contamination of the detergent box 2. In addition, the dispensing pump 3 realizes precise control of the amount of detergent dispensed, thereby preventing manual addition from causing excessive or insufficient detergent.

[0059] Optionally, see Figure 6 The spray pipe 4 includes a multi-way pipe 41 and a pipe body 42. The multi-way pipe 41 is provided with at least two liquid inlets 411 and a connecting port 412, and the at least two liquid inlets 411 are respectively connected with the liquid outlet 32 ​​and the water inlet valve 1; one end of the pipe body 42 is connected with the connecting port 412, and the other end is provided with a liquid outlet.

[0060] By setting the multi-way pipe 41, the spray pipe 4 is provided with multiple liquid inlets 411. There is no need to specially customize the spray pipe 4 of this structure. The common pipe body can be plugged into a multi-way pipe 41, which saves the mold cost of making a special structure spray pipe 4. The structure is simple and easy to install. If the pipe body is damaged, it can be directly replaced, and the maintenance cost is low. In addition, the multi-way pipe 41 is arranged at one end of the pipe body 42 close to the water inlet valve 1, which prolongs the time for water to dissolve the detergent and improves the dissolution rate of the detergent.
