The installation groove 3221 can be arranged to extend vertically. The installation groove 3221 can extend up and down. The side edge of the filter member 321 can be inserted downward into the installation groove 3221 from the upper port of the installation groove 3221, and then the filter member 321 is vertically arranged between the liquid storage area 3201 and the filtering area 3202.

[0089] In some embodiments, there may be two installation grooves 3221. The two installation grooves 3221 may be respectively disposed on opposite side walls of the liquid storage cavity 320. Opposite side edges of the filter element 321 may be respectively inserted downward from the upper ports of the installation grooves 3221 into an installation groove 3221, so that the filter element 321 can be detachably arranged between the liquid storage area 3201 and the filtration area 3202.

[0090] Please refer to Figure 9 As shown, in some embodiments, an installation position 322 may be formed between the liquid storage area 3201 and the filtration area 3202. The filter element 321 may be detachably disposed in the installation position 322. The installation position 322 may extend vertically so that the filter element 321 can be erected between the liquid storage area 3201 and the filtration area 3202.

[0091] In some embodiments, the two installation grooves 3221 may be respectively disposed on opposite side walls of the installation position 322. When the filter element 321 is disposed in the installation position 322, opposite ends of the filter element 321 may be respectively inserted into an installation groove 3221, thereby fixing the filter element 321 in the installation position 322.

[0092] In some embodiments, a positioning card slot 3222 may be provided at the bottom of the installation position 322. When the filter element 321 is disposed in the installation position 322, the bottom end of the filter element 321 may be inserted into the positioning card slot 3222, thereby fixing the filter element 321 in the installation position 322.

[0093] Please refer to Figures 6 to 8 As shown, in some embodiments, the top of the soap box 32 may have a box cover 323. The box cover 323 may cover the top surface of the liquid storage cavity 320.

[0094] In some embodiments, the box cover 323 may be provided with a liquid replenishing port 3231. The liquid replenishing port 3231 may be located above the top of the liquid storage area 3201. When the soap box 32 is pulled out from the water inlet box 31, the user can replenish the laundry detergent into the liquid storage cavity 320 through the liquid replenishing port 3231. The laundry detergent may first enter the liquid storage area 3201 and then flow into the filtration area 3202 after being filtered by the filter element 321.

[0095] 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 can 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.

[0096] In some embodiments, a valve plug 3232 may be provided at the liquid replenishing port 3231. The valve plug 3232 may be detachably provided at the liquid replenishing port 3231. The valve plug 3232 may be used to seal and block the liquid replenishing port 3231. The valve plug 3232 may be removed from the liquid replenishing port 3231 by manually pulling it out. The valve plug 3232 may be plugged at the liquid replenishing port 3231 by manually inserting it.

[0097] 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 cover 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.

[0098] Please refer to Figures 6 to 8 As shown, in some embodiments, a manual feeding slot 324 may be provided in the soap box 32. The manual feeding slot 324 may be internally communicated with the water inlet box 31. The user may directly put laundry detergents such as detergents and fabric conditioners 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 fed into the washing cavity 20 in the drum assembly 2 through the water flow in the water inlet box 31.

[0099] Figure 10 is Figure 9 the front view of. Figure 11 is Figure 10 the sectional view taken along the line A-A in. Figure 12 is Figure 7 the structural schematic diagram of the box cover 323 in.

[0100] Please refer to Figures 10 to 12 As shown, in some embodiments, a manual feeding port 3234 may be formed in the box cover 323. The manual feeding port 3234 may be provided at the top of the manual feeding slot 324. The manual feeding port 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 may directly put laundry detergents into the manual feeding slot 324 from the manual feeding port 3234.

[0101] In some embodiments, when the user uses washing powder to wash clothes, the user may put the washing powder into the manual feeding slot 324 through the manual feeding port 3234, and the washing powder in the manual feeding slot 324 may be flushed into the washing cavity 20 by the water flow in the water inlet box 31. In this scenario, the user may independently control the amount of washing powder used for each laundry.

[0102] In some embodiments, when a user does a single laundry, the user can also put the amount of laundry detergent for a single laundry into the manual dosing tank 324 through the manual dosing port 3234, and the laundry detergent in the manual dosing tank 324 is flushed into the washing chamber 20 by the water flow in the water inlet box 31. In this scenario, the user can independently control the amount of laundry detergent for a single laundry.

[0103] It should be noted that when the user replenishes the laundry detergent into the liquid storage chamber 320 through the replenishment port 3231, the user does not need to consider the amount of laundry detergent for a single laundry, but rather consider the total amount of laundry detergent for multiple laundries that needs to be replenished in the liquid storage chamber 320.

[0104] Please refer to Figures 8 to 11 As shown, in some embodiments, the height of the bottom surface of the filtration 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 filtration 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 filtration area 3202 may be equal to the height of the bottom surface of the liquid storage area 3201. Therefore, when the laundry detergent in the filtration area 3202 is pumped out, the laundry detergent in the liquid storage area 3201 can automatically flow to the filtration area 3202 and flow into the filtration area 3202 after being filtered by the filter element 321.

[0105] In some embodiments, the height of the bottom surface of the end of the liquid storage area 3201 close to the filtration area 3202 may be lower than the height of the bottom surface of the end of the liquid storage area 3201 far from the filtration area 3202. Therefore, when the laundry detergent in the filtration area 3202 is pumped out, the laundry detergent in the liquid storage area 3201 can automatically move in the direction close to the liquid storage area 3201.

[0106] 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 filtration 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 filtration area 3202 may be higher than the height of the bottom surface of the end of the liquid storage area 3201 close to the filtration area 3202, enabling the laundry detergent in the liquid storage area 3201 to automatically move in the direction close to the liquid storage area 3201.

[0107] In some embodiments, the entire bottom surface of the liquid storage area 3201 may be the diversion wall 3203. At this time, the entire bottom surface of the liquid storage area 3201 may be arranged to extend obliquely, enabling the laundry detergent in the liquid storage area 3201 to automatically move in the direction close to the liquid storage area 3201.

[0108] Please refer to Figure 11As shown, in some embodiments, the bottom surface height of the filtering area 3202 may be equal to the bottom surface height of one end of the liquid storage area 3201 close to the filtering area 3202. It should be noted that, in other embodiments, the bottom surface height of the filtering area 3202 may also be lower than the bottom surface height of one end of the liquid storage area 3201 close to the filtering area 3202.

[0109] Figure 13 is Figure 12 a partially enlarged structural schematic diagram of the middle liquid extraction tube 325. Figure 14 is Figure 13 a disassembled structural schematic diagram of Figure 15 is Figure 10 a sectional view taken along the line B-B in Figure 16 is Figure 15 a partially enlarged structural schematic diagram of

[0110] Please refer to Figures 12 to 16 As shown, in some embodiments, a liquid extraction tube 325 may be provided in the soap box 32. The liquid extraction tube 325 may be arranged in the liquid storage cavity 320. The liquid extraction tube 325 may be arranged in the filtering area 3202. The liquid extraction tube 325 may be communicated with the liquid inlet end of the dosing pump 33. The dosing pump 33 may extract the laundry detergent in the filtering area 3202 of the liquid storage cavity 320 through the liquid extraction tube 325.

[0111] In some embodiments, the liquid extraction tube 325 may be arranged to extend vertically. The upper end inside the liquid extraction tube 325 may be communicated with the liquid inlet end of the dosing pump 33. The lower end of the liquid extraction tube 325 may be communicated with the bottom area of the liquid storage cavity 320. The lower end of the liquid extraction tube 325 may be communicated with the bottom area of the filtering area 3202. Therefore, the dosing pump 33 may extract the clean laundry detergent in the filtering area 3202 through the liquid extraction tube 325.

[0112] In some embodiments, the liquid extraction tube 325 may be provided on the bottom surface of the box cover 323. The liquid extraction tube 325 may extend downward from the bottom surface of the box cover 323. The box cover 323 may 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 may extend downward from the bottom surface of the box cover 323 into the filtering area 3202, and the bottom end of the liquid extraction tube 325 may be communicated with the bottom area of the filtering area 3202.

[0113] In some embodiments, the liquid extraction tube 325 may be integrally formed with the box cover 323. The liquid extraction tube 325 may be integrally formed on the bottom surface of the box cover 323, and thus the liquid extraction tube 325 and the box cover 323 may be integrally formed through an injection molding process to simplify the manufacturing and assembly difficulty of the liquid extraction tube 325.

[0114] 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.

[0115] In other embodiments, the liquid extraction tube 325 can also be separately arranged from the box cover 323. The liquid extraction tube 325 can be separately arranged in the liquid storage cavity 320. The liquid extraction tube 325 can be detachably and separately arranged in the liquid storage cavity 320, or the liquid extraction tube 325 can also be integrally formed and fixed in the liquid storage cavity 320.

[0116] Please refer to Figure 6 and Figure 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 towards 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, which is convenient for the liquid extraction tube 325 to 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 filtering 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.

[0117] 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 arranged 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 from the liquid extraction tube 325. The internal space of the existing liquid extraction tube 325 is relatively large. During use, especially during the first use, the extracted laundry detergent needs to preferentially fill the internal space 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 and reduce the occupation of the internal space of the liquid extraction tube 325 by the laundry detergent.

[0118] It should be noted that in some related technologies, the internal space of the liquid extraction tube 325 is reduced by narrowing the internal diameter of the liquid extraction tube 325, but this solution is likely to block the liquid extraction tube 325 and it is difficult to accurately control the dosing flow rate and speed of the laundry detergent.

[0119] In some embodiments, a flow reduction channel 3260 may be provided inside the flow reduction tube 326. The upper end of the flow reduction channel 3260 may communicate with the inside of the liquid extraction tube 325. The lower end of the flow reduction channel 3260 may communicate with the inside of the liquid storage cavity 320. Therefore, the liquid extraction tube 325 can communicate with the bottom area of the liquid storage cavity 320 through the flow reduction channel 3260, and the liquid inlet end 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.

[0120] 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 flow 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.

[0121] It should be noted that the internal space of the existing liquid extraction tube 325 is constant, and it is difficult to adjust and precisely control the liquid extraction flow rate of the liquid extraction tube 325. In some embodiments of the present application, different models of flow reduction tubes 326 can be replaced inside the liquid extraction tube 325. Different models of flow reduction tubes 326 can have flow reduction channels 3260 with different diameters. By replacing the flow reduction tube 326 with a flow reduction 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 amount of the dosing pump 33, precisely controlling the dosing speed and dosing amount of the laundry detergent, and reducing the dosing error.

[0122] Please refer to Figure 16 As shown, in some embodiments, the liquid extraction tube 325 may be arranged to extend vertically. The vertical arrangement of the liquid extraction tube 325 can facilitate the installation and arrangement of the liquid extraction tube 325. The flow reduction tube 326 is arranged to extend vertically. The extension direction of the flow reduction tube 326 may be the same as the extension direction of the liquid extraction tube 325, so as to simplify the manufacturing and installation difficulty of the flow reduction tube 326.

[0123] It should be noted that in some other embodiments, the liquid extraction tube 325 may also be arranged obliquely. There may be an angle between the liquid extraction tube 325 and the vertical direction. Correspondingly, the flow reduction tube 326 may also be arranged obliquely. There may be an angle between the flow reduction tube 326 and the vertical direction.

[0124] In some embodiments, the flow reduction channel 3260 in the flow reduction tube 326 may be arranged to extend along the axial direction of the flow reduction tube 326, which can simplify the manufacturing process difficulty of the flow reduction tube 326. It should be noted that in some other embodiments, the flow reduction channel 3260 in the flow reduction tube 326 may not extend along the axial direction of the flow reduction tube 326, and the flow reduction channel 3260 in the flow reduction tube 326 may also be arranged in a curved or inclined manner.

[0125] Please refer toFigure 14 , Figure 16 As shown, in some embodiments, fixing ribs 3261 may protrude from the outer peripheral wall of the volume-reducing tube 326. The fixing ribs 3261 may be arranged to extend vertically. The fixing ribs 3261 may be arranged to extend along the axial direction of the volume-reducing tube 326.

[0126] When the volume-reducing tube 326 is installed inside the liquid extraction tube 325, the outer side wall of the fixing rib 3261 can abut against the inner wall of the liquid extraction tube 325. By means of interference extrusion, the volume-reducing tube 326 can be fixed inside the liquid extraction tube 325.

[0127] In some embodiments, in the direction from bottom to top, the distance between the outer side wall of the fixing rib 3261 and the outer peripheral wall of the volume-reducing tube 326 may gradually decrease to zero. In the direction from bottom to top, the thickness of the fixing rib 3261 may gradually decrease to zero. Therefore, when the volume-reducing tube 326 is installed inside the liquid extraction tube 325, there may be a zero gap between the outer peripheral wall at the top end of the volume-reducing tube 326 and the inner wall of the liquid extraction tube 325, and the outer peripheral wall at the top end of the volume-reducing 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-reducing channel 3260 inside the volume-reducing tube 326.

[0128] In some embodiments, the fixing rib 3261 may only be arranged in the lower region of the outer peripheral wall of the volume-reducing tube 326. The fixing rib 3261 is not arranged in the top region of the outer peripheral wall of the volume-reducing tube 326, so as to ensure that the outer peripheral wall at the top end of the volume-reducing tube 326 can closely adhere to the inner wall of the liquid extraction tube 325.

[0129] It should be noted that, in other embodiments, the fixing rib 3261 may only be arranged in the middle region of the outer peripheral wall of the volume-reducing tube 326.

[0130] Please refer to Figure 14 As shown, in some embodiments, there may be multiple fixing ribs 3261. The multiple fixing ribs 3261 may be circumferentially spaced and arranged on the outer peripheral wall of the volume-reducing tube 326. The multiple fixing ribs 3261 can improve the stability of fixing the volume-reducing tube 326 inside the liquid extraction tube 325. 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.

[0131] Please refer to Figures 12 to 16As shown, in some embodiments, a stepped groove 3251 may be recessed laterally at the bottom port of the liquid extraction tube 325. The stepped groove 3251 may be in an annular structure. The stepped groove 3251 may be arranged around the peripheral side wall of the bottom port of the liquid extraction tube 325. A stepped portion 3262 may be protruded on the outer peripheral wall at the bottom end of the volume reduction tube 326. The stepped portion 3262 may be in an annular structure. The stepped portion 3262 may be arranged around the outer peripheral wall at 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, so that 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 excessively 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.

[0132] Please refer to Figures 12 to 16 As shown, in some embodiments, a first protrusion 3252 extending downward may be protruded on the peripheral side wall of the bottom port of the liquid extraction tube 325. The first protrusion 3252 may 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.

[0133] In some embodiments, a plurality of first protrusions 3252 extending downward may be protruded on the peripheral side wall of the bottom port of the liquid extraction tube 325. The plurality of first protrusions 3252 may be circumferentially spaced and arranged at the peripheral side edge of the bottom port of the liquid extraction tube 325. A first flow-through gap 3253 may be formed between two adjacent first protrusions 3252. When the distance between the first protrusion 3252 and the bottom surface of the liquid storage cavity 320 is small, or when the first protrusion 3252 abuts against the bottom surface of the liquid storage cavity 320, the bottom port of the liquid extraction tube 325 may extract the laundry detergent in the liquid storage cavity 320 through the first flow-through gap 3253.

[0134] It should be noted that the number and spacing of the first protrusions 3252 may be adjusted as needed and are not limited herein.

[0135] Please refer to Figures 12 to 16 As shown, in some embodiments, a second protrusion 3263 extending downward may be protruded on the peripheral side wall of the bottom port of the volume reduction tube 326. The second protrusion 3263 may protrude beyond the bottom port of the liquid extraction tube 325. The second protrusion 3263 may 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.

[0136] In some embodiments, a plurality of second protrusions 3263 extending downwardly may be protrudingly provided on the circumferential sidewall of the bottom port of the volume reduction tube 326. The plurality of second protrusions 3263 may 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 may be formed between two adjacent second protrusions 3263. When the distance between the second protrusion 3263 and the bottom surface of the liquid storage cavity 320 is small, or when the second protrusion 3263 abuts against the bottom surface of the liquid storage cavity 320, the liquid extraction tube 325 may 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.

[0137] It should be noted that the number and spacing of the second protrusions 3263 can be adjusted as needed and are not limited herein.

After the step of dispensing the laundry detergent in the constant volume chamber 314 into the washing chamber 20 along with the water flow in the premixing water channel 315 is completed, the main water inlet channel 317 may supply water to the constant volume chamber 314 through the first branch 3172 to wash the residual laundry detergent in the constant volume chamber 314.

[0150] In some embodiments, the main water inlet channel 317 may be recessed on the top surface of the water distribution plate 312. The main water inlet channel 317 may be enclosed between the bottom surface of the top cover 313 and the top surface of the water distribution plate 312.

[0151] Please refer to Figure 18 、 Figure 19 As shown, in some embodiments, an overflow port 3141 may be provided on the side wall of the constant volume chamber 314. The overflow port 3141 may connect the constant volume chamber 314 and the dispensing chamber 310. When the liquid in the constant volume chamber 314 reaches a preset height, the liquid in the constant volume chamber 314 can flow into the dispensing chamber 310 through the overflow port 3141, and then flow into the washing chamber 20 in the drum assembly 2 through the water outlet part 311 at the bottom of the dispensing chamber 310.

[0152] In some embodiments, the height between the overflow port 3141 and the bottom surface of the constant volume chamber 314 may be a preset height. When the liquid in the constant volume chamber 314 reaches the preset height, the liquid level in the constant volume chamber 314 reaches the overflow port 3141, and the liquid volume in the constant volume chamber 314 is the preset volume.

[0153] Please refer to Figure 18 、 Figure 19 As shown, in some embodiments, when the main water inlet channel 317 supplies water to the constant volume chamber 314 through the first branch 3172, the mixed liquid after the water flow washes the residual laundry detergent in the constant volume chamber 314 can flow into the dispensing chamber 310 through the overflow port 3141, and then flow into the washing chamber 20 in the drum assembly 2 through the water outlet part 311 at the bottom of the dispensing chamber 310.

[0154] In some embodiments, the port where the first branch 3172 is connected to the constant volume chamber 314 may be arranged on the top side wall of the constant volume chamber 314, so as to facilitate washing the residual laundry detergent on the inner side wall of the constant volume chamber 314.

[0155] 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 liquid overflow port 3141, so that the liquid in the constant volume chamber 314 can smoothly drain from the liquid overflow port 3141, preventing the liquid from flowing back into the first branch 3172 and the main water inlet path 317.

[0156] Please refer to Figure 18 , Figure 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.

[0157] 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.

[0158] It should be noted that when water is supplied into the constant volume chamber 314 through the first branch 3172 for cleaning, most of the mixed liquid of the residual laundry detergent in the constant volume chamber 314 during cleaning flows into the dosing chamber 310 through the liquid overflow port 3141. Only at the end of the cleaning process or when the water supply ends, most of the liquid components in the constant volume chamber 314 are 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.

[0159] Please refer to Figure 18 , Figure 19 , and in combination with Figures 3 to 5 As shown, in some embodiments, a first outlet 3151 can be formed at the water outlet end of the premixing water path 315. The dosing assembly 3 can include a dosing tube 34. The dosing tube 34 can be provided outside the water inlet box 31. One end of the dosing tube 34 can communicate with the first outlet 3151.

The mixed liquid formed in the premixing water path 315 can be delivered through the dosing tube 34 and put into the washing chamber 20 of the drum assembly 2.

[0160] In some embodiments, the main water inlet waterway 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 be formed with a second outlet 3174. The dosing assembly 3 may include a cleaning pipe 35. The cleaning pipe 35 may be disposed outside the water inlet box 31. One end of the cleaning pipe 35 may communicate with the second outlet 3174. The other end of the cleaning pipe 35 may communicate with the washing chamber 20. The main water inlet waterway 317 can clean a partial area in the washing chamber 20 of the drum assembly 2 through the second branch 3173 and the cleaning pipe 35. It should be noted that the main water inlet waterway 317 can supply water to the washing chamber 20 of the drum assembly 2 through the second branch 3173 and the cleaning pipe 35.

[0161] In some embodiments, the cleaning area of the cleaning pipe 35 in the washing chamber 20 and the dosing area of the dosing pipe 34 in the washing chamber 20 may at least partially overlap. In the washing chamber 20, the cleaning area of the cleaning pipe 35 and the dosing area of the dosing pipe 34 may mostly overlap, so as to flush the residual laundry detergent on the inner wall of the washing chamber 20 through the second branch 3173 and the cleaning pipe 35, which is beneficial to improving the laundry efficiency and reducing the residual laundry detergent on the inner wall of the washing chamber 20.

[0162] Please refer to Figures 17 to 19 As shown, in some embodiments, a spray chamber 318 may be provided in the water inlet box 31. The spray chamber 318 may be disposed on the top surface of the water distribution plate 312. The spray chamber 318 may be enclosed between the top surface of the water distribution plate 312 and the bottom surface of the top cover 313. The spray chamber 318 may be arranged above the top of the manual dosing slot 324. A plurality of spray nozzles 3181 may be provided on the bottom surface of the spray chamber 318. The plurality of spray nozzles 3181 may be arranged on the bottom surface of the spray chamber 318 at intervals. The spray nozzles 3181 may communicate with the manual dosing slot 324.

[0163] When water is supplied to the spray chamber 318 from a water source, the water in the spray chamber 318 may be sprayed downward through the plurality of spray nozzles 3181 onto the manual dosing slot 324 to flush the washing powder or laundry detergent in the manual dosing slot 324. The washing powder or laundry detergent is flushed into the dosing chamber 310 by the water flow, and then is discharged into the washing chamber 20 of the drum assembly 2 through the water outlet part 311 at the bottom of the dosing chamber 310 by the water flow.

[0164] It should be noted that in other embodiments, the spray chamber 318 may also directly supply water to the washing chamber 20 in the drum assembly 2 through the spray nozzles 3181, the manual dosing slot 324, and the dosing chamber 310.

[0165] Please refer to Figures 17 to 19As shown, in some embodiments, the main water inlet channel 317 may include a third branch 3175. One end of the third branch 3175 may communicate with the main water inlet 3171. The other end of the third branch 3175 may communicate with the spray chamber 318. The main water inlet channel 317 can supply water to the spray chamber 318 through the third branch 3175, and thus can supply water to the washing chamber 20 of the cylinder assembly 2, or can convey the washing powder or liquid detergent in the manual dosing tank 324 into the washing chamber 20.

[0166] Please refer to Figure 3 , Figure 18 , Figure 20 As shown, in some embodiments, the dosing assembly 3 may include a water inlet valve 36. The water inlet valve 36 may have a first valve port 361. The first valve port 361 may be connected to the water inlet end of the premixing water channel 315 through a premixing water inlet pipe 37.
