[0057] like Figure 2 , Figure 4 and Figure 5 As shown, in the embodiment of the present invention, a cylindrical protrusion 215 is provided on the first section wall 2111, which protrudes into the delivery box 21 and has openings at both ends. The inner peripheral wall of the cylindrical protrusion 215 and the openings at both ends form a guide channel. The opening of the cylindrical protrusion 215 extending into the delivery cavity serves as a liquid adding port 214 of the delivery device 2, and a liquid delivery port 213 of the delivery device 2 is provided on the peripheral wall of the cylindrical protrusion 215.

[0058] In the embodiment of the present invention, one end of the cylindrical protrusion 215 is open and disposed on the first wall 2111, and the other end of the cylindrical protrusion 215 is open and extends into the delivery box 21;

[0059] The liquid injection port 213 of the dispensing device 2 is arranged on the first section wall 2111. Specifically, the liquid injection port 213 of the dispensing device 2 is arranged on the cylindrical protrusion 215. At the same time, the liquid injection port 213 of the dispensing device 2 is arranged on the first section wall 2111 on the outer periphery of the cylindrical protrusion 215, which can increase the liquid injection area and increase the uniformity of the clothing treatment agent dispensed into the inner drum by the dispensing box 21.

[0060] After the delivery box 21 is removed from the accommodating chamber 121, the first wall section 2111 is placed upward, and the liquid adding port 214 of the delivery device 2 is set upward, and the clothes treatment agent is delivered into the delivery box 21;

[0061] The clothing treatment agent is added into the delivery box 21 through the guide channel and the liquid adding port 214 of the delivery device 2. The guide channel can guide the clothing treatment agent to the liquid adding port 214 of the delivery device 2, that is, to the other end of the cylindrical protrusion 215 extending into the delivery box 21, thereby guiding the clothing treatment agent into the delivery box 21, accelerating the addition of the clothing treatment agent and preventing the clothing treatment agent from leaking out.

[0062] The delivery box 21 is installed in the accommodating chamber 121 for delivering the clothing treatment agent, the lifting rib 1 and the delivery box 21 are arranged at the bottom of the inner drum, and the liquid delivery port 213 and the liquid filling port 214 of the delivery device 2 are arranged upward in the inner drum; when delivering, water is first introduced into the outer drum or the inner drum, the water level is higher than the lifting rib 1, the water enters the delivery box 21, and then the lifting rib 1 and the delivery box 21 are rotated to the highest point driven by the rotation of the inner drum; after the lifting rib 1 with the delivery box 21 is rotated to the highest point of the inner drum, it swings left and right driven by the rotation of the inner drum, so that the liquid delivery port 213 of the delivery device 2 is arranged downward, and the liquid delivery port 213 of the delivery device 2 evenly sprinkles the clothing treatment agent on the clothes.

[0063] Specifically, the cylindrical protrusion 215 gradually narrows from the outside to the inside of the delivery box 21 , which can further accelerate the entry of the clothing treatment agent into the delivery box 21 and prevent the clothing treatment agent from remaining on the inner peripheral wall of the cylindrical protrusion 215 .

[0064] A plurality of liquid injection ports 213 of the dispensing device 2 are distributed on the peripheral wall of the cylindrical protrusion 215. The liquid injection port 213 of each dispensing device 2 is oriented in the same direction as the liquid adding port 214 of the dispensing device 2. When adding liquid, the clothing treatment agent is prevented from flowing out of the liquid injection port 213 of the dispensing device 2 to the outside. After the dispensing device 2 is placed in the accommodating cavity 121, the clothing treatment agent is prevented from flowing out of the liquid adding port 214 of the dispensing device 2 to the outside. When the clothing treatment agent is dispensed, part of the clothing treatment agent flows out of the liquid adding port 214 of the dispensing device 2.

[0065] Furthermore, a plurality of annular observation windows coaxial with the cylindrical protrusion 215 are provided on the peripheral wall of the cylindrical protrusion 215. By providing a plurality of annular observation windows, the amount of clothing treatment agent in the dispensing box 21 can be clearly known, which helps the user to judge the amount of clothing treatment agent and form a usage habit. The annular observation windows are made of transparent material.

[0066] like Figure 3 and Figure 5 As shown, in the embodiment of the present invention, a guide rib 216 extending toward the liquid adding port 214 of the dispensing device 2 and guiding the laundry treating agent is provided in the dispensing box 21, and the guide rib 216 is spaced apart from the liquid adding port 214 of the dispensing device 2.

[0067] In an embodiment of the present invention, the guide rib 216 can guide the clothing treatment agent entering from the liquid adding port 214 of the dispensing device 2 to all sides to prevent the clothing treatment agent from splashing and remaining on the inner box wall 212 of the dispensing box; and when the inner drum rotates, the clothing treatment agent is more likely to leak out from the liquid adding port 213 of the dispensing device 2, thereby increasing the uniformity of the clothing treatment agent dispensing and reducing the amount of clothing treatment agent leaking from the liquid adding port 214 of the dispensing device 2.

[0068] Specifically, the guide rib 216 is columnar, and the guide rib 216 gradually narrows from the inside of the delivery box 21 to the outside, which can speed up the guidance of the clothes treatment agent to the surroundings and improve the accuracy of the guidance of the clothes treatment agent;

[0069] The guide rib 216 is coaxially arranged with the liquid adding port 214 of the dispensing device 2, and the radial dimension of the liquid adding port 214 of the dispensing device 2 is larger than the radial dimension of the small-sized end of the guide rib 216, so that the clothes treating agent entering from the liquid adding port 214 of the dispensing device 2 can contact the small-sized end of the guide rib 216 and can be guided by the small-sized end of the guide rib 216;

[0070] The radial dimension of the liquid adding port 214 of the dispensing device 2 is smaller than the radial dimension of the large-sized end of the guide rib 216, which can further disperse the clothes treating agent from the small-sized end of the guide rib 216 to the surroundings, so that the area where the clothes treating agent is dispersed becomes larger.

[0071] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
