[0094] In some embodiments, the box cover 323 may be provided with two liquid replenishing ports 3231. The two liquid replenishing ports 3231 may be respectively located above the tops of the two liquid storage cavities 320. Therefore, the user may replenish the detergent into one liquid storage cavity 320 through one liquid replenishing port 3231 and replenish the fabric softener into the other liquid storage cavity 320 through the other liquid replenishing port 3231.

[0095] In some embodiments, a valve plug 3232 may be provided at the liquid replenishing port 3231. The valve plug 3232 may be detachably disposed at the liquid replenishing port 3231. The valve plug 3232 may be used to seal and block the liquid replenishing port 3231.

[0096] In some embodiments, the box cover 323 may be provided with a liquid replenishing cover 3233. The liquid replenishing cover 3233 may be rotatably connected to the top surface of the box cover 323. The liquid replenishing cover 3233 may be covered on the top surfaces of the liquid replenishing port 3231 and the valve plug 3232, thereby sealing the liquid replenishing port 3231 and the valve plug 3232.

[0097] Please refer to Figures 6 to 8As shown, in some embodiments, a manual feeding slot 324 may be provided in the soap box 32. The manual feeding slot 324 may be in internal communication with the water inlet box 31. The user can directly put laundry detergents such as detergents and fabric softeners into the manual feeding slot 324, so that the laundry detergents can enter the interior of the water inlet box 31 along the manual feeding slot 324 and can be directly put into the washing cavity 20 in the drum assembly 2 through the water flow.

[0098] In some embodiments, a manual feeding opening 3234 may be formed in the box cover 323. The manual feeding opening 3234 may be provided at the top of the manual feeding slot 324. The manual feeding opening 3234 may be vertically and directly communicated with the manual feeding slot 324. When the soap box 32 is pulled out from the water inlet box 31, the user can directly put laundry detergents into the manual feeding slot 324 from the manual feeding opening 3234.

[0100] Please refer to Figures 8 to 11 As shown, in some embodiments, the height of the bottom surface of the liquid outlet area 3202 may not be higher than the height of the bottom surface of the liquid storage area 3201. That is, the height of the bottom surface of the liquid outlet area 3202 may be lower than the height of the bottom surface of the liquid storage area 3201, or the height of the bottom surface of the liquid outlet area 3202 may be equal to the height of the bottom surface of the liquid storage area 3201. Therefore, when the laundry detergents in the liquid outlet area 3202 are pumped out, the laundry detergents in the liquid storage area 3201 can automatically flow towards the liquid outlet area 3202 and flow into the liquid outlet area 3202 after being filtered by the filter element 321.

[0101] In some embodiments, the height of the bottom surface of one end of the liquid storage area 3201 close to the liquid outlet area 3202 may be lower than the height of the bottom surface of the end of the liquid storage area 3201 far from the liquid outlet area 3202. Therefore, when the laundry detergents in the liquid outlet area 3202 are pumped out, the laundry detergents in the liquid storage area 3201 can automatically move towards the direction close to the liquid storage area 3201.

[0102] In some embodiments, a diversion wall 3203 may be provided on the bottom surface of the liquid storage area 3201. The diversion wall 3203 may be provided at the middle position of the liquid storage area 3201. In the direction from the liquid storage area 3201 towards the liquid outlet area 3202, the diversion wall 3203 may be arranged to extend obliquely downward, so that the height of the bottom surface of the end of the liquid storage area 3201 far from the liquid outlet area 3202 may be higher than the height of the bottom surface of the end of the liquid storage area 3201 close to the liquid outlet area 3202, enabling the laundry detergents in the liquid storage area 3201 to automatically move towards the direction close to the liquid storage area 3201.

[0103] In some embodiments, the entire bottom surface of the liquid storage area 3201 can be a diversion wall 3203. At this time, the entire bottom surface of the liquid storage area 3201 can be arranged to extend obliquely, so that the laundry detergent in the liquid storage area 3201 can automatically move towards the direction close to the liquid storage area 3201.

[0104] Please refer to Figure 11 As shown, in some embodiments, the bottom surface height of the liquid outlet area 3202 can be equal to the bottom surface height of the end of the liquid storage area 3201 close to the liquid outlet area 3202. It should be noted that in other embodiments, the bottom surface height of the liquid outlet area 3202 can also be lower than the bottom surface height of the end of the liquid storage area 3201 close to the liquid outlet area 3202.

[0105] Figure 12 is Figure 7 a schematic structural diagram of the middle box cover 323. Figure 13 is Figure 12 a partially enlarged structural diagram of the liquid extraction tube 325 in the middle. Figure 14 is Figure 13 a disassembled structural diagram of Figure 15 is Figure 10 a sectional view taken along the line B-B in the middle. Figure 16 is Figure 15 a partially enlarged structural diagram of

[0106] Please refer to Figures 12 to 16 As shown, in some embodiments, a liquid extraction tube 325 can be provided in the soap box 32. The liquid extraction tube 325 can be arranged in the liquid storage cavity 320. The liquid extraction tube 325 can be arranged in the liquid outlet area 3202. The liquid extraction tube 325 can be communicated with the liquid inlet end of the dosing pump 33. The dosing pump 33 can extract the laundry detergent in the liquid outlet area 3202 of the liquid storage cavity 320 through the liquid extraction tube 325.

[0107] In some embodiments, the liquid extraction tube 325 can be arranged to extend vertically. The upper end in the liquid extraction tube 325 can be communicated with the liquid inlet end of the dosing pump 33. The lower end of the liquid extraction tube 325 can be communicated with the bottom area of the liquid storage cavity 320. The lower end of the liquid extraction tube 325 can be communicated with the bottom area of the liquid outlet area 3202. Therefore, the dosing pump 33 can extract the laundry detergent in the liquid outlet area 3202 cleanly through the liquid extraction tube 325.

[0108] In some embodiments, the liquid extraction tube 325 can be provided on the bottom surface of the box cover 323. The liquid extraction tube 325 can extend downward from the bottom surface of the box cover 323. The box cover 323 can be detachably provided on the top of the soap box 32. When the box cover 323 is installed on the top of the soap box 32, the liquid extraction tube 325 can extend downward from the bottom surface of the box cover 323 into the liquid outlet area 3202, and the bottom end of the liquid extraction tube 325 can be communicated with the bottom area of the liquid outlet area 3202.

[0109] In some embodiments, the liquid extraction tube 325 can be integrally formed with the box cover 323. The liquid extraction tube 325 can be integrally formed on the bottom surface of the box cover 323.

[0110] It should be noted that, in other embodiments, the liquid extraction tube 325 can also be detachably connected to the box cover 323. The liquid extraction tube 325 can also be detachably arranged on the bottom surface of the box cover 323.

[0111] Please refer to Figures 6 to 16 As shown, in some embodiments, a docking tube 3235 can be provided at the rear end of the box cover 323. The docking tube 3235 can extend toward the back side of the soap box 32. The upper end of the liquid extraction tube 325 can be communicated with the docking tube 3235. When the soap box 32 is pushed into the water inlet box 31, the docking tube 3235 can be docked and communicated with the liquid inlet end of the dosing pump 33. Therefore, the liquid inlet end of the dosing pump 33 can extract the laundry detergent in the liquid outlet area 3202 of the liquid storage cavity 320 through the docking tube 3235 and the liquid extraction tube 325, so that the laundry detergent passes through the inside of the liquid extraction tube 325 and the inside of the docking tube 3235 in sequence, and then enters the inside of the dosing pump 33.

[0112] Please refer to Figures 12 to 16 As shown, in some embodiments, a volume reduction tube 326 can be provided inside the liquid extraction tube 325. The volume reduction tube 326 can be detachably provided inside the liquid extraction tube 325, so that the volume reduction tube 326 can be put into the liquid extraction tube 325 or taken out of the liquid extraction tube 325. The volume reduction tube 326 can be filled in the internal space of the liquid extraction tube 325 to reduce the internal space of the liquid extraction tube 325.

[0113] In some embodiments, a flow reduction channel 3260 can be provided inside the volume reduction tube 326. The upper end of the flow reduction channel 3260 can be communicated with the inside of the liquid extraction tube 325. The lower end of the flow reduction channel 3260 can be communicated with the inside of the liquid storage cavity 320. Therefore, the liquid extraction tube 325 can be communicated with the bottom area of the liquid storage cavity 320 through the flow reduction channel 3260, and the liquid inlet of the dosing pump 33 can extract the laundry detergent in the liquid storage cavity 320 through the liquid extraction tube 325 and the flow reduction channel 3260, and then the extracted laundry detergent can be dosed into the washing cavity 20.

[0114] When the dosing assembly 3 is in use, especially during the first use, filling the internal space of the liquid extraction tube 325 with the volume reduction tube 326 can reduce the occupation of the internal space of the liquid extraction tube 325 by the laundry detergent, and thus can avoid affecting the dosing amount of the laundry detergent and reduce the dosing error of the laundry detergent.

[0115] It should be noted that in some embodiments, different models of volume reduction tubes 326 can be replaced within the liquid extraction tube 325. Different models of volume reduction tubes 326 can have throttling channels 3260 with different diameters. By replacing the volume reduction tube 326 with a throttling channel 3260 of a different diameter, the liquid extraction speed of the dosing pump 33 can be changed and adjusted, facilitating the precise control of the liquid extraction volume of the dosing pump 33, and precisely controlling the dispensing speed and dispensing volume of the laundry detergent to reduce the dispensing error.

[0116] Please refer to Figure 16 As shown, in some embodiments, the liquid extraction tube 325 can be arranged to extend vertically. The volume reduction tube 326 is arranged to extend vertically. The extending direction of the volume reduction tube 326 can be the same as the extending direction of the liquid extraction tube 325.

[0117] It should be noted that in some other embodiments, the liquid extraction tube 325 can also be arranged obliquely. There can be an angle between the liquid extraction tube 325 and the vertical direction. Correspondingly, the volume reduction tube 326 can also be arranged obliquely. There can be an angle between the volume reduction tube 326 and the vertical direction.

[0118] In some embodiments, the throttling channel 3260 within the volume reduction tube 326 can be arranged to extend along the axial direction of the volume reduction tube 326. It should be noted that in some other embodiments, the throttling channel 3260 within the volume reduction tube 326 may not extend along the axial direction of the volume reduction tube 326, and the throttling channel 3260 within the volume reduction tube 326 can also be arranged in a curved or inclined manner.

[0119] Please refer to Figure 14 、 Figure 16 As shown, in some embodiments, fixing ribs 3261 can be convexly provided on the outer peripheral wall of the volume reduction tube 326. The fixing ribs 3261 can be arranged to extend vertically. The fixing ribs 3261 can be arranged to extend along the axial direction of the volume reduction tube 326.

[0120] When the volume reduction tube 326 is installed inside the liquid extraction tube 325, the outer side wall of the fixing rib 3261 can be in contact with the inner wall of the liquid extraction tube 325, and the volume reduction tube 326 can be fixed inside the liquid extraction tube 325 by means of interference extrusion.

[0121] In some embodiments, in the upward direction, the distance between the outer sidewall of the fixing rib 3261 and the outer peripheral wall of the volume reduction tube 326 may gradually decrease to zero. In the upward direction, the thickness of the fixing rib 3261 may gradually decrease to zero. Therefore, when the volume reduction tube 326 is installed inside the liquid extraction tube 325, a zero gap may be maintained between the outer peripheral wall of the top end of the volume reduction tube 326 and the inner wall of the liquid extraction tube 325, and the outer peripheral wall of the top end of the volume reduction tube 326 may closely adhere to the inner wall of the liquid extraction tube 325. When the liquid inlet end of the dosing pump 33 extracts liquid, the dosing pump 33 can only extract the laundry detergent in the liquid storage chamber 320 through the flow reduction channel 3260 inside the volume reduction tube 326.

[0122] In some embodiments, the fixing rib 3261 may be arranged only in the lower region of the outer peripheral wall of the volume reduction tube 326. The fixing rib 3261 is not arranged in the top region of the outer peripheral wall of the volume reduction tube 326, thereby ensuring that the outer peripheral wall of the top end of the volume reduction tube 326 can closely adhere to the inner wall of the liquid extraction tube 325.

[0123] It should be noted that, in other embodiments, the fixing rib 3261 may be arranged only in the middle region of the outer peripheral wall of the volume reduction tube 326.

[0124] Please refer to Figure 14 As shown, in some embodiments, there may be a plurality of fixing ribs 3261. The plurality of fixing ribs 3261 may be circumferentially spaced and arranged on the outer peripheral wall of the volume reduction tube 326. It should be noted that the number, length, and thickness of the fixing ribs 3261 can be adjusted as needed and are not limited herein.

[0125] Please refer to Figures 12 to 16 As shown, in some embodiments, a stepped groove 3251 may be recessed on the circumferential side at the bottom port of the liquid extraction tube 325. The stepped groove 3251 may have an annular structure. The stepped groove 3251 may be arranged around the circumferential sidewall of the bottom port of the liquid extraction tube 325. A stepped portion 3262 may be protruded on the outer peripheral wall of the bottom end of the volume reduction tube 326. The stepped portion 3262 may have an annular structure. The stepped portion 3262 may be arranged around the outer peripheral wall of the bottom end of the volume reduction tube 326. When the volume reduction tube 326 needs to be placed inside the liquid extraction tube 325, the volume reduction tube 326 may be inserted into the liquid extraction tube 325 through the bottom port of the liquid extraction tube 325, and the stepped portion 3262 may be fitted into the stepped groove 3251, thereby fixing the volume reduction tube 326 inside the liquid extraction tube 325, preventing the volume reduction tube 326 from extending too far into the liquid extraction tube 325, and preventing the volume reduction tube 326 from being unable to be taken out of the liquid extraction tube 325.

[0126] Please refer to Figures 12 to 16As shown, in some embodiments, a first protrusion portion 3252 extending downward may be convexly provided on the circumferential side wall of the bottom port of the liquid extraction tube 325. The first protrusion portion 3252 can be used to abut against the bottom surface of the liquid storage cavity 320 to maintain a gap between the bottom port of the liquid extraction tube 325 and the bottom surface of the liquid storage cavity 320.

[0127] In some embodiments, a plurality of first protrusion portions 3252 extending downward may be convexly provided on the circumferential side wall of the bottom port of the liquid extraction tube 325. The plurality of first protrusion portions 3252 can be circumferentially spaced and arranged at the circumferential side edge of the bottom port of the liquid extraction tube 325. A first flow-through gap 3253 can be formed between two adjacent first protrusion portions 3252. When the distance between the first protrusion portion 3252 and the bottom surface of the liquid storage cavity 320 is small, or when the first protrusion portion 3252 abuts against the bottom surface of the liquid storage cavity 320, the bottom port of the liquid extraction tube 325 can extract the laundry detergent in the liquid storage cavity 320 through the first flow-through gap 3253.

[0128] It should be noted that the number and spacing of the first protrusion portions 3252 can be adjusted as needed and are not limited herein.

[0129] Please refer to Figures 12 to 16 As shown, in some embodiments, a second protrusion portion 3263 extending downward may be convexly provided on the circumferential side wall of the bottom port of the volume reduction tube 326. The second protrusion portion 3263 can protrude from the bottom port of the liquid extraction tube 325. The second protrusion portion 3263 can be used to abut against the bottom surface of the liquid storage cavity 320 to maintain a gap between the bottom port of the volume reduction tube 326 and the bottom surface of the liquid storage cavity 320.

[0130] In some embodiments, a plurality of second protrusion portions 3263 extending downward may be convexly provided on the circumferential side wall of the bottom port of the volume reduction tube 326. The plurality of second protrusion portions 3263 can be circumferentially spaced and arranged at the circumferential side edge of the bottom port of the volume reduction tube 326. A second flow-through gap 3264 can be formed between two adjacent second protrusion portions 3263. When the distance between the second protrusion portion 3263 and the bottom surface of the liquid storage cavity 320 is small, or when the second protrusion portion 3263 abuts against the bottom surface of the liquid storage cavity 320, the liquid extraction tube 325 can extract the laundry detergent in the liquid storage cavity 320 through the bottom port of the flow reduction channel 3260 and the second flow-through gap 3264.

[0131] It should be noted that the number and spacing of the second protrusion portions 3263 can be adjusted as needed and are not limited herein.

The soap box 32 may be slidably disposed in the dosing chamber 310 through the front end opening of the water inlet box 31.

[0134] In some embodiments, a water outlet portion 311 may be provided at the bottom of the water inlet box 31. A water outlet (not labeled in the figure) may be provided in the water outlet portion 311. The water outlet in the water outlet portion 311 may communicate with the washing chamber 20. The water or laundry detergent entering the dosing chamber 310 may flow into the washing chamber 20 of the drum assembly 2 through the water outlet in the water outlet portion 311.

[0135] Figure 19 is Figure 18 a schematic structural view of the water distribution plate in

[0136] Please refer to Figures 17 to 19 shown. In some embodiments, the water inlet box 31 may include a water distribution plate 312. The water distribution plate 312 may be disposed above the top of the dosing chamber 310. A water passage may be provided in the water inlet box 31. The water passage may be disposed in the water distribution plate 312. One end of the water passage may be connected to a water source. The other end of the water passage may be communicated with the washing chamber 20 in the drum assembly 2 through a pipeline. The other end of the water passage may also be communicated with the dosing chamber 310, and the dosing chamber 310 is then communicated with the washing chamber 20 in the drum assembly 2 through a pipeline.

[0137] In some embodiments, the water inlet box 31 may include a top cover 313. The top cover 313 may be disposed on the top surface of the water distribution plate 312. The water passage may be formed by enclosing between the top surface of the water distribution plate 312 and the bottom surface of the top cover 313.

[0139] Please refer to Figures 17 to 22 shown. In some embodiments, a constant volume chamber 314 may be provided in the water inlet box 31. The constant volume chamber 314 may be recessed on the top surface of the water distribution plate 312. The constant volume chamber 314 may be formed by enclosing between the top surface of the water distribution plate 312 and the bottom surface of the top cover 313. The liquid outlet end of the dosing pump 33 may be communicated with the constant volume chamber 314. When the dosing pump 33 operates, the liquid inlet end of the dosing pump 33 may extract the laundry detergent in the liquid storage chamber 320 of the soap box 32, and convey the extracted laundry detergent to the constant volume chamber 314 through the liquid outlet end of the dosing pump 33.

[0140] Please refer to Figures 17 to 19 As shown, in some embodiments, the water passage in the water inlet box 31 may include a premixing water passage 315. One end of the premixing water passage 315 may be connected to a water source. The other end of the premixing water passage 315 may be used to communicate with the washing cavity 20. The premixing water passage 315 may be connected to the constant volume cavity 314 through a pipeline. When water enters the premixing water passage 315, the premixing water passage 315 may extract the laundry detergent in the constant volume cavity 314, mix it with the water in the premixing water passage 315, and then deliver it to the washing cavity 20 through the pipeline for feeding.

[0141] In some embodiments, the premixing water passage 315 may be recessed on the top surface of the water distribution plate 312. At least part of the pipeline of the premixing water passage 315 may be enclosed between the bottom surface of the top cover 313 and the top surface of the water distribution plate 312.

[0142] Please refer to Figures 17 to 19 As shown, in some embodiments, the water passage in the water inlet box 31 may include a main water inlet passage 317. The main water inlet passage 317 may have a main water inlet 3171. The main water inlet 3171 may be used to communicate with a water source. The main water inlet passage 317 may include a first branch 3172. One end of the first branch 3172 may communicate with the main water inlet 3171. The other end of the first branch 3172 may communicate with the constant volume cavity 314. After the feeding step in which the laundry detergent in the constant volume cavity 314 is delivered to the washing cavity 20 along with the water flow in the premixing water passage 315 ends, the main water inlet passage 317 may supply water to the constant volume cavity 314 through the first branch 3172 to clean the residual laundry detergent in the constant volume cavity 314.

[0143] In some embodiments, the main water inlet passage 317 may be recessed on the top surface of the water distribution plate 312. The main water inlet passage 317 may be enclosed between the bottom surface of the top cover 313 and the top surface of the water distribution plate 312.

[0144] Please refer to Figures 17 to 19 As shown, in some embodiments, an overflow port 3141 may be provided on the side wall of the constant volume cavity 314. The overflow port 3141 may communicate the constant volume cavity 314 and the feeding cavity 310. When the liquid in the constant volume cavity 314 reaches a preset height, the liquid in the constant volume cavity 314 can flow into the feeding cavity 310 through the overflow port 3141, and then flow into the washing cavity 20 in the cylinder assembly 2 through the water outlet part 311 at the bottom of the feeding cavity 310.

[0145] In some embodiments, the height between the overflow port 3141 and the bottom surface of the constant volume cavity 314 may be a preset height. When the liquid in the constant volume cavity 314 reaches the preset height, the liquid level height in the constant volume cavity 314 reaches the position of the overflow port 3141, and the liquid volume in the constant volume cavity 314 is the preset volume.

[0146] Please refer toFigures 17 to 19 As shown, in some embodiments, when the main water inlet channel 317 supplies water into the constant volume chamber 314 through the first branch 3172, the mixed liquid after the water flow cleans the residual laundry detergent in the constant volume chamber 314 can flow through the overflow port 3141 into the dosing chamber 310, and then flow into the washing chamber 20 in the drum assembly 2 through the water outlet part 311 at the bottom of the dosing chamber 310.

[0147] In some embodiments, the port where the first branch 3172 communicates with the constant volume chamber 314 can be arranged on the top side wall of the constant volume chamber 314, so as to facilitate cleaning the residual laundry detergent on the inner side wall of the constant volume chamber 314.

[0148] In some embodiments, the position height of the port where the first branch 3172 communicates with the constant volume chamber 314 can be higher than the position height of the overflow port 3141, so that the liquid in the constant volume chamber 314 can smoothly drain from the overflow port 3141, preventing the liquid from flowing back into the first branch 3172 and the main water inlet channel 317.

[0149] Please refer to Figures 17 to 19 As shown, in some embodiments, a water leakage port 3142 can be provided on the bottom surface of the constant volume chamber 314. The water leakage port 3142 can communicate with the dosing chamber 310. When the first branch 3172 supplies water into the constant volume chamber 314, the water for cleaning the residual laundry detergent in the constant volume chamber 314 can enter the dosing chamber 310 through the water leakage port 3142.

[0150] In some embodiments, the diameter of the water leakage port 3142 can be less than or equal to a preset diameter. When the laundry detergent in the liquid storage chamber 320 enters the constant volume chamber 314, due to the viscosity of the laundry detergent, the laundry detergent in the constant volume chamber 314 cannot enter the dosing chamber 310 through the water leakage port 3142.

[0151] It should be noted that when the constant volume chamber 314 is cleaned by supplying water through the first branch 3172, most of the mixed liquid for cleaning the residual laundry detergent in the constant volume chamber 314 flows into the dosing chamber 310 through the overflow port 3141. Only at the end of the cleaning process or when the water supply ends, most of the liquid component in the constant volume chamber 314 is water, and at this time, the liquid in the constant volume chamber 314 can enter the dosing chamber 310 through the water leakage port 3142.

[0152] Please refer to Figures 17 to 19 , and in combination with Figures 3 to 5As shown, in some embodiments, a first outlet 3151 may be formed at the water outlet end of the premixed water path 315. The dosing assembly 3 may include a dosing tube 34. The dosing tube 34 may be disposed outside the water inlet box 31. One end of the dosing tube 34 may communicate with the first outlet 3151. The other end of the dosing tube 34 may communicate with the washing chamber 20. The mixed liquid formed in the premixed water path 315 can be delivered through the dosing tube 34 and put into the washing chamber 20 of the drum assembly 2.

[0153] In some embodiments, the main water inlet path 317 may include a second branch 3173. One end of the second branch 3173 may communicate with the main water inlet 3171. The other end of the second branch 3173 may form a second outlet 3174. The dosing assembly 3 may include a cleaning tube 35. The cleaning tube 35 may be disposed outside the water inlet box 31. One end of the cleaning tube 35 may communicate with the second outlet 3174. The other end of the cleaning tube 35 may communicate with the washing chamber 20. The main water inlet path 317 can clean a partial area in the washing chamber 20 of the drum assembly 2 through the second branch 3173 and the cleaning tube 35.
