The drum assembly is arranged inside the casing, and the drum assembly includes an outer drum and an inner drum, and a washing cavity is formed in the inner drum. A clothing delivery port is arranged on the top surface of the casing. A liquid delivery groove is recessed on the top of the casing, and liquids such as disinfectants are delivered into the area between the outer drum and the inner drum below it through the liquid delivery groove, so that the liquids such as disinfectants are mixed with water and enter the washing cavity of the inner drum.

[0004] Among the current liquid delivery solutions for pulsator washing machines, some solutions have a relatively wide liquid delivery slot design. The liquid delivery slot is arranged on the side of the clothing delivery port and directly above the area between the outer drum and the inner drum, which requires a large width and area on the top of the casing, resulting in a reduced width of the clothing delivery port, which brings inconvenience to clothing delivery. The liquid delivery slot of some solutions is designed to be close to the clothing delivery port, which will affect the appearance of the product and there is a risk that the delivered liquids such as disinfectants will come into direct contact with the clothing.

The liquid entering the liquid channel 40 can be introduced downward into the liquid storage tank 330 through the inner port of the liquid channel 40, and flow downward into the space between the inner cylinder 32 and the outer cylinder 31 through the second liquid leakage port 3301 of the liquid outlet tank. Therefore, the liquid in the liquid delivery tank 110 is introduced into the liquid storage tank 330 through the liquid channel 40, and flows into the space between the inner cylinder 32 and the outer cylinder 31 through the liquid storage tank 330.

[0096] It should be noted that, by extending the liquid channel 40 in the adapter 4 toward the center of the barrel assembly 3, the liquid delivery groove 110 and the space between the inner barrel 32 and the outer barrel 31 can be spaced in the radial direction of the barrel assembly 3, which is beneficial to increase the radial spacing between the liquid delivery groove 110 and the clothing delivery port 10, so that the liquid delivery groove 110 does not need to be directly arranged above the space between the inner barrel 32 and the outer barrel 31, which is beneficial to maintaining the beautiful appearance of the product and avoiding the liquid delivery structure affecting the size of the clothing delivery port 10.

[0097] See also Fig. 9 As shown, in some embodiments, the inner port of the liquid channel 40 can be arranged above the top of the space between the inner cylinder 32 and the outer cylinder 31. In this case, the cylinder assembly 3 may not be provided with a liquid storage tank 330. The liquid in the liquid delivery tank 110 is directly introduced downward into the space between the inner cylinder 32 and the outer cylinder 31 through the inner port of the liquid channel 40.

[0098] See also Figures 9 and 10As shown, in some embodiments, the inner bottom surface of the liquid channel 40 can be an inclined surface. The inner bottom surface of the liquid channel 40 can be arranged to extend downwardly and tilted toward the center direction of the barrel assembly 3. The liquid channel 40 can be an inclined channel structure. The liquid channel 40 can be arranged to extend downwardly and tilted toward the center direction of the barrel assembly 3. The liquid entering the liquid channel 40 can automatically move toward the inner port of the liquid channel 40, and then be introduced downward into the liquid storage tank 330 through the inner port of the liquid channel 40, and then flow downward into the space between the inner cylinder 32 and the outer cylinder 31.

[0109] Based on the above technical solution, the embodiment of the utility model has at least the following advantages and positive effects:

[0110] In the pulsator washing machine of the present utility model, the liquid delivery tank 110 is arranged at intervals on the peripheral side of the clothing delivery port 10. The liquid in the liquid delivery tank 110 can be introduced into the space between the inner drum 32 and the outer drum 31 through the liquid channel 40 in the adapter 4, mixed with the water in the space between the inner drum 32 and the outer drum 31, and then enters the washing chamber 30 inside the inner drum 32. By extending the liquid channel 40 in the adapter 4 toward the center direction of the drum assembly 3, the liquid delivery tank 110 and the space between the inner drum 32 and the outer drum 31 can be spaced in the radial direction of the drum assembly 3, which is conducive to increasing the radial spacing between the liquid delivery tank 110 and the clothing delivery port 10, so that the liquid delivery tank 110 does not need to be directly arranged above the space between the inner drum 32 and the outer drum 31, which is conducive to maintaining the beauty of the product appearance and avoiding the liquid delivery structure affecting the size of the clothing delivery port 10.
