The port 43 is connected, the upper end of the first vertical pipe 811 is connected with one end of the horizontal pipe 812, the lower end of the second vertical pipe 813 is connected with the liquid passage 45, and the upper end of the second vertical pipe 813 is connected with the other end of the horizontal pipe 812. The structure is compact and the space occupied by the flushing pipe 81 is reduced.

As shown in FIGS. 21 to 25 , in some examples, a three-way pipe 70 is provided on the drop box 40 , the first interface 71 of the three-way pipe 70 is communicated with the first liquid outlet 43 , and the second interface of the three-way pipe 70 is connected 72 is connected to the door seal spray hole on the first washing tub through the connecting pipe, so that the washing water flowing out of the first liquid outlet 43 can flow into the first washing tub through the door seal, so that the water intake process can be intuitive for the user. It is obviously observed that at the same time, a better flushing effect can be formed on the door seal; the third interface 73 of the three-way pipe 70 is communicated with the liquid-passing cavity 51 through the flushing flow channel 60, and the washing water flowing out from the first liquid outlet 43 It can also flow into the liquid passage chamber 51 through the flushing channel 60; wherein, the height of the third interface 73 is higher than the height of the second interface 72, thereby ensuring that the washing water preferentially flows into the washing tub. In the case of large water flow and sufficient water volume down, the washing water flows into the flushing channel 60 . By arranging the three-way pipe 70, the flushing flow channel 60 can be formed without additionally arranging an opening on the throwing assembly 200, which reduces the difficulty of the manufacturing process, and is simple in assembly and convenient for connection.

In addition, the detergent flowing out through the first liquid outlet 43 can be directly passed into the first washing tub below, or can be passed into the first washing tub below through the flushing channel 60 and the liquid passage cavity 51, so as to ensure the first washing tub below. All the detergent flowing out of a liquid outlet 43 leads to the first washing tub; thus, the first washing tub can also realize double water inlet, and a multi-directional three-dimensional water flow is formed in the first washing tub to improve the cleaning effect.

As shown in FIG. 22 , in some examples, the three-way pipe 70 includes a vertical pipe section 74 and a horizontal pipe section 75 , two ends of the vertical pipe section 74 respectively form a first interface 71 and a third interface 73 , and the first interface 71 is located in the vertical The lower end of the straight pipe section 74, the third interface 73 is located at the upper end of the vertical pipe section 74, one end of the horizontal pipe section 75 is communicated with the middle of the vertical pipe section 74, and the other end of the horizontal pipe forms a second interface 72 for connecting with the washing tub, As a result, the height of the third port 73 is higher than that of the second port 72 to ensure that the washing water preferentially flows to the washing tub.

Therefore, according to the laundry treatment device of the embodiment of the present application, the first washing tub and the second washing tub can be used alone or synchronously, and both the washing tubs can realize the function of automatically adding detergent; and the detergent box 100 The liquid accumulation chamber 102 is communicated with the liquid passage chamber 51, so that the user does not need to manually clean the liquid accumulation chamber 102, and the detergent in the liquid passage chamber 51 is flushed through the flushing channel 60, so there is no need to manually clean the liquid passage chamber 51, which improves the use of the user. In addition, through the first roller assembly 15 and the second roller assembly 25, the movable cavity 20 and the fixed cavity 10 can achieve rolling cooperation, improve the smoothness of pushing and pulling, and further improve the user's operating experience; Each cavity is provided with a roller assembly, and the structures of the two roller assemblies are the same, so that the number of parts and costs can be reduced, and at the same time, the operation in a small space in the detergent box 100 can be satisfied, the installation difficulty is reduced, and the operation and stability are improved. The feasibility of assembly is improved, thereby improving the market competitiveness of the detergent box 100 .
