[0010] In some embodiments, the perforated region is provided on both sides of the non-perforated region along the second direction.

[0011] In some embodiments, the bottom wall of the detergent box is provided with a water-blocking rib and a second drain outlet. The water-blocking rib divides the space inside the detergent box into a mixing chamber and an overflow chamber. The second drain outlet is used to discharge the detergent mixture solution in the overflow chamber into the detergent dispensing device.

[0012] In some embodiments, the filter element has its two ends along the second direction in contact with the first sub-wall and the second sub-wall, respectively, and its two ends along the first direction in contact with the side wall of the detergent box and the water-blocking rib, respectively.

[0032] This application provides a detergent dispensing device; please refer to [link / reference]. Figures 1 to 6 The detergent dispensing device 10 includes a detergent box 11, a dispenser box 12, and a filter element 13. The detergent box 11 has a mixing chamber 11a and a first drain outlet 11c, the first drain outlet 11c being disposed on the wall of the mixing chamber 11a. The dispenser box 12 is disposed within the detergent box 11, and the dispenser box 12 forms a detergent dispensing chamber 12a. The filter element 13 is disposed within the detergent box 11, and the filter element 13 has a through-hole 13a. Detergent and / or detergent mixture discharged from the detergent dispensing chamber 12a can enter the mixing chamber 11a through the through-hole 13a.

[0033] This application also provides a clothing processing device. The type of clothing processing device is not limited, for example, it can be a washing machine, a washer-dryer combo, etc.

[0034] Please see Figures 1 to 4 The garment processing equipment includes a garment processing chamber and a detergent dispensing device 10 as described in any embodiment of this application. The first drain outlet 11c of the detergent dispensing device 10 is connected to the garment processing chamber. The first drain outlet 11c is used to guide the mixed solution in the mixing chamber 11a into the garment processing chamber.

[0035] It should be noted that the detergent mixture mentioned in this instruction manual is for ease of description only, referring to a solution containing dissolved detergent, and its mass percentage concentration is not limited. Of course, the detergent mixture does not mean that the detergent is completely dissolved.

[0036] The form of detergent is not limited; it can be powdered laundry detergent, liquid laundry detergent, or liquid fabric softener, etc.

[0037] For example, the detergent dispensing device 10 also includes a water path that flows through the detergent dispensing chamber 12a and the first drain outlet 11c. The fluid from the water source introduced by the water path enters the detergent dispensing chamber 12a, mixes with the detergent to form a detergent mixture solution, and is discharged from the detergent box 11 through the first drain outlet 11c.

[0038] It should be noted that the water source mentioned above refers to the water source that supplies fluid to the water system, such as tap water; it can also be the internal water source of the clothing processing equipment, such as circulating water.

[0039] In some embodiments, please refer to Figure 4 The dispenser box 12 is removably disposed inside the detergent box 11, for example, the dispenser box 12 is at least partially pulled out of the detergent box 11 in a horizontal direction to the outside of the detergent box 11.

[0040] For example, the detergent dispenser 11 is provided with a pull-out opening 11e, and the dispenser box 12 is provided in the detergent dispenser 11 in a first direction via the pull-out opening 11e.

[0041] It should be noted that in the embodiments of this application, waterway refers to the flow path of fluid and does not specifically refer to a pipe structure.

[0042] The detergent dispenser 11 also has a mixing chamber 11a, which is used to collect the fluid flowing through the detergent dispensing chamber 12a. A first drain outlet 11c is disposed on the wall of the mixing chamber 11a. That is, the mixture containing detergent enters the mixing chamber 11a and is discharged from the first drain outlet 11c.

[0043] For example, please refer to Figure 4 The mixing chamber 11a is located below the dispenser box 12. The detergent mixture flows from the detergent dispensing chamber 12a of the dispenser box 12 to the mixing chamber 11a below the dispenser box 12 and is discharged from the first drain port 11c.

[0044] In some embodiments, please refer to Figures 2 to 5 The detergent dispenser 11 also has an overflow chamber 11b and a second drain outlet 11d. The overflow chamber 11b is used to collect the detergent mixture overflowing from the mixing chamber 11a, and the second drain outlet 11d is used to discharge the detergent mixture in the overflow chamber 11b into the detergent dispenser 11.

[0045] In this embodiment, when the water level in the mixing chamber 11a is not higher than the overflow level, the fluid in the mixing chamber 11a is discharged from the first drain port 11c and flows to the cylinder assembly 20. When the water level in the mixing chamber 11a is higher than the overflow level, the excess water overflows into the overflow chamber 11b and is discharged from the second drain port 11d. That is to say, the detergent box 11 preferentially discharges water from the first drain port 11c, and the second drain port 11d plays a safety protection role, which can discharge excess water in the mixing chamber 11a in a timely manner.

[0046] For example, the fluid cross-sectional area of ​​the second drain outlet 11d is larger than that of the first drain outlet 11c. That is, when the water volume is equal and sufficient, the drainage volume of the second drain outlet 11d is greater than that of the first drain outlet 11c.

[0047] Because the cross-sectional area of ​​the fluid in the first drain outlet 11c is relatively small, the outflow rate of the first drain outlet 11c is relatively small. However, the second drain outlet 11d and the overflow chamber 11b can promptly discharge the fluid in the detergent box in the event of overflow, reducing water blockage in the detergent box 11 and playing a safety protection role.

[0048] Here, the detergent mixture discharged from the detergent dispensing chamber 12a is either a liquid detergent mixture or a powder detergent mixture, especially a powder detergent mixture. Powder detergent is more prone to clogging and residue buildup compared to liquid detergent, potentially reducing the reliability of the detergent dispensing device 10. However, by providing a filter element 13, the detergent mixture discharged from the detergent dispensing chamber 12a passes through the through-hole 13a and enters the mixing chamber 11a. In other words, the filter element 13 can filter the detergent mixture.

[0049] It should be noted that the specific structure of the filter element 13 is not limited here. For example, the filter element 13 is a filter plate.

[0050] For example, please refer to Figure 4 At least a portion of the dispenser box 12 is provided with an outlet 11n spaced apart from the side wall of the detergent box 11, through which the detergent and / or detergent mixture in the detergent dispensing chamber 12a can be discharged from the detergent dispensing chamber 12a.

[0051] Here, when projected onto a plane perpendicular to the height direction of the detergent dispensing device 10, there is no through hole 13a within the projection range of the outlet 11n. After the detergent mixture is discharged from the detergent dispensing chamber 12a through the outlet 11n, it will not flow directly into the mixing chamber 11a from the corresponding through hole 13a within the projection range of the outlet 11n. This helps to increase the flow path of the detergent mixture between the outlet 11n and the through hole 13a.

[0052] It should be noted that the height direction of the detergent dispensing device 10 is the same as the height direction of the clothing processing equipment.

[0053] The detergent dispensing device provided in this application embodiment, by providing a filter element 13 inside the detergent box 11, allows the detergent mixture discharged from the detergent dispensing chamber 12a to enter the mixing chamber 11a through the through holes 13a of the filter element 13. In this way, on the one hand, before the detergent enters the clothing processing chamber, the dissolution of the detergent can be further promoted, and the mixing uniformity of the detergent and water can be improved, thereby improving the utilization efficiency of the detergent; on the other hand, the filter element 13 can filter large particles of laundry powder, which can further promote the dissolution of the detergent while improving the situation where large particles of laundry powder clog the first drain outlet 11c.

[0054] In some embodiments, please refer to Figures 2 to 5 The detergent dispenser 11 includes a first sub-wall 111 and a second sub-wall 112 arranged along a second direction. The first sub-wall 111 and the second sub-wall 112 are connected. The end of the first sub-wall 111 near the second sub-wall 112 is lower than the end of the first sub-wall 111 away from the second sub-wall 112 in the height direction of the detergent dispensing device 10. The end of the second sub-wall 112 near the first sub-wall 111 is lower than the end of the second sub-wall 112 away from the first sub-wall 111 in the height direction of the detergent dispensing device 10. The first sub-wall 111 and the second sub-wall 112 define at least a portion of the mixing chamber 11a.

[0055] For example, both the first sub-wall 111 and the second sub-wall 112 extend along a first direction.

[0056] The intersection of the first direction and the second direction means that the first direction and the second direction are not parallel; for example, the first direction and the second direction are perpendicular to each other.

[0057] For example, the first direction is, for instance, the pull-out direction of the dispenser box 12, or the sliding direction of the dispenser box 12. Correspondingly, the height direction of the detergent dispensing device 10 is the direction of gravity, and the first direction is perpendicular to the height direction of the detergent dispensing device 10. Correspondingly, the second direction is perpendicular to both the height direction of the detergent dispensing device 10 and the first direction.

[0058] It should be noted that the first sub-wall 111 and the second sub-wall 112 defining at least a portion of the mixing cavity 11a means that the first sub-wall 111 and the second sub-wall 112 can define either a portion of the mixing cavity 11a or all of the mixing cavity 11a.

[0059] Here, the end of the first sub-wall 111 near the second sub-wall 112 is lower than the end of the first sub-wall 111 away from the second sub-wall 112 in the height direction of the detergent dispensing device 10. That is, the first sub-wall 111 is inclined along the second direction. The end of the second sub-wall 112 near the first sub-wall 111 is lower than the end of the second sub-wall 112 away from the first sub-wall 111 in the height direction of the detergent dispensing device 10. That is, the second sub-wall 112 is inclined along the second direction. In other words, the connection between the first sub-wall 111 and the second sub-wall 112 is lower than the surrounding area. That is, the bottom wall of the detergent box 11 is roughly V-shaped. In this way, by setting the first drain outlet 11c at the connection between the first sub-wall 111 and the second sub-wall 112, it is beneficial for the detergent mixture in the mixing chamber 11a to be guided to the cylinder assembly 20 through the first drain outlet 11c as much as possible.

[0060] The first sub-wall 111 is inclined along the second direction. It can be that part of the first sub-wall 111 is inclined along the second direction, or all of the first sub-wall 111 is inclined along the second direction.

[0061] Similarly, the second sub-wall 112 is inclined along the second direction, which can be either a partial or complete inclination of the second sub-wall 112 along the second direction.

[0062] In this embodiment, by setting the end of the first sub-wall 111 near the second sub-wall 112 in the height direction of the detergent dispensing device 10 to be lower than the end of the first sub-wall 111 and farther away from the second sub-wall 112, and setting the end of the second sub-wall 112 near the first sub-wall 111 in the height direction of the detergent dispensing device 10 to be lower than the end of the second sub-wall 112 and farther away from the first sub-wall 111, the first drain outlet 11c can be set at the connection between the first sub-wall 111 and the second sub-wall 112. This facilitates the detergent mixture in the mixing chamber 11a to be guided to the cylinder assembly 20 through the first drain outlet 11c as much as possible, thereby improving the utilization efficiency of the detergent.

[0063] In some embodiments, please refer to Figure 5 and Figure 6 The filter element 13 includes an open area 13b with through holes 13a and a non-porous area 13c without through holes 13a. Projected onto a plane perpendicular to the height direction of the detergent dispensing device 10, the projection of the junction of the first sub-wall 111 and the second sub-wall 112 at least partially overlaps with the projection of the non-porous area 13c.

[0064] Here, the filter element 13 can be divided into an open area 13b and a non-open area 13c. The open area 13b is provided with a through hole 13a, while the non-open area 13c is not provided with a through hole 13a.

[0065] The projection at the junction of the first sub-wall 111 and the second sub-wall 112 at least partially overlaps with the projection of the non-porous region 13c, meaning that the projection at the junction of the first sub-wall 111 and the second sub-wall 112 at least partially overlaps with the projection of the non-porous region 13c; or the projection at the junction of the first sub-wall 111 and the second sub-wall 112 at least partially overlaps with the projection of the non-porous region 13c.

[0066] It is understandable that the detergent mixture discharged from the detergent dispensing chamber 12a is a laundry liquid mixture or a laundry powder mixture, especially a laundry powder mixture. Since laundry powder is a powdered detergent, if a perforation 13a is provided at the connection between the first sub-wall 111 and the second sub-wall 112 corresponding to the area of ​​the filter element 13, the laundry powder can easily be deposited directly through the perforation 13a and remain at the connection between the first sub-wall 111 and the second sub-wall 112, which may reduce the utilization rate of the detergent.

[0067] In this embodiment, by ensuring that the projection of the connection between the first sub-wall 111 and the second sub-wall 112 does not exceed the projection range of the non-porous region 13c, that is, the area of ​​the filter element 13 corresponding to the connection between the first sub-wall 111 and the second sub-wall 112 is not provided with through holes 13a, the situation where laundry detergent is directly deposited and remains at the connection between the first sub-wall 111 and the second sub-wall 112 through through holes 13a can be improved, which is beneficial to improving the utilization rate of detergent.

[0068] In some embodiments, the projection at the junction of the first sub-wall 111 and the second sub-wall 112 does not exceed the projection range of the non-porous region 13c.

[0069] In some embodiments, please refer to Figure 6 The dimension of the non-porous region 13c in the second direction is 2mm-20mm.

[0070] For example, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, etc.

[0071] It is understandable that the smaller the size of the non-porous region 13c in the second direction, the more through holes 13a can be set on the filter element 13, which is beneficial to improving the liquid flow efficiency; the larger the size of the non-porous region 13c in the second direction, the larger the distance between the connection between the first sub-wall 111 and the second sub-wall 112 and the perforated region 13b in the second direction, which is better at improving the direct deposition and residue of laundry detergent at the connection between the first sub-wall 111 and the second sub-wall 112.

[0072] In this embodiment, by setting the size of the non-porous region 13c in the second direction to 2mm-20mm, the filter element 13 can have a certain liquid flow efficiency, while also helping to further improve the situation where laundry detergent is directly deposited and remains on the first sub-wall 111 and the second sub-wall 112.

[0073] In some embodiments, please refer to Figure 2 and Figure 6 The non-perforated region 13c has perforated regions 13b on both sides along the second direction.

[0074] The non-perforated region 13c has perforated regions 13b on both sides along the second direction. That is, there are multiple perforated regions 13b, and at least two perforated regions 13b are spaced apart in the second direction. For example, one perforated region 13b corresponds to the first sub-wall 111, and the other perforated region 13b corresponds to the second sub-wall 112.

[0075] In this embodiment, by providing perforated regions 13b on both sides of the non-porous region 13c along the second direction, the detergent mixture discharged from the detergent dispensing chamber 12a can enter the mixing chamber 11a through the through holes 13a of the perforated regions 13b on both sides, and be guided to the clothing processing chamber through the first drain outlet 11c. This improves the situation where laundry detergent is directly deposited through the through holes 13a and remains at the junction of the first sub-wall 111 and the second sub-wall 112, which is beneficial to improving the utilization rate of detergent.

[0076] It should be noted that the specific manner in which the detergent box 11 is configured with the mixing chamber 11a and the overflow chamber 11b is not limited here.

[0077] In some embodiments, please refer to Figures 2 to 5 The bottom wall of the detergent dispenser 11 is provided with a water-retaining rib 113 and a second drain outlet 11d. The water-retaining rib 113 divides the space inside the detergent dispenser 11 into a mixing chamber 11a and an overflow chamber 11b. The second drain outlet 11d is used to discharge the detergent mixture solution in the overflow chamber 11b into the detergent dispensing device 10.

[0078] For example, the second drain outlet 11d is disposed on the cavity wall of the overflow cavity 11b.

[0079] The overflow water level in the mixing chamber 11a is determined by the structure of the baffle 113. Specifically, the overflow water level is the lowest water level that the baffle 113 allows the water in the mixing chamber 11a to flow into the overflow chamber 11b.

[0080] For example, in some embodiments, the height of the top edge of the water-blocking rib 113 is used as the overflow water level of the mixing chamber 11a. When the water level in the mixing chamber 11a continues to rise to the top edge of the water-blocking rib 113, the water overflows the water-blocking rib 113, flows from the top side of the water-blocking rib 113 to the overflow chamber 11b on the second side of the water-blocking rib 113, and is discharged from the second drain outlet 11d.

[0081] In other embodiments, the water-blocking rib 113 is provided with a notch, and the height of the bottom edge of the notch is used as the overflow water level of the mixing chamber 11a.

[0082] It should be noted that the specific location of the filter element 13 is not restricted here.

[0083] In some embodiments, please refer to Figure 2 and Figure 5 The filter element 13 is in contact with the first sub-wall 111 and the second sub-wall 112 at both ends along the second direction, and in contact with the side wall of the detergent box 11 and the water-blocking rib 113 at both ends along the first direction.

[0084] In other words, in some embodiments, the filter element 13, together with the first sub-wall 111, the second sub-wall 112, the sidewall of the detergent box 11, and the water-blocking rib 113, defines the mixing chamber 11a.

[0085] Here, the filter element 13 is in contact with the water-blocking rib 113. The filter element 13 can be placed on the top of the water-blocking rib 113, or the filter element 13 can abut against the side wall of the water-blocking rib 113.

[0086] For example, the end of the first sub-wall 111 away from the second sub-wall 112 may also be provided with a first sidewall, and the end of the second sub-wall 112 away from the first sub-wall 111 may also be provided with a second sidewall, and the two ends of the filter element 13 along the second direction respectively contact the first sidewall of the first sub-wall 111 and the second sidewall of the second sub-wall 112.

[0087] In some embodiments, please refer to Figure 6 The filter element 13 includes a body portion and a thinning region. At least a portion of the periphery of the body portion is provided with a thinning region. The thickness of the thinning region is less than the thickness of the body portion. Furthermore, the thickness of the thinning region decreases in the direction away from the body portion.

[0088] The phrase "at least a portion of the area around the body is provided with a thinning zone" means that either a thinning zone is provided in a portion of the area around the body, or a thinning zone is provided in the entire area around the body.

[0089] At least a portion of the periphery of the main body is provided with a thinning zone, that is, the thickness of the edge of the filter element 13 is reduced.

[0090] In this embodiment, by providing a thinning zone in at least a portion of the periphery of the main body, and the thickness of the thinning zone decreasing in the direction away from the main body, it is beneficial to make the edge of the filter element 13 fit better with the detergent box 11, and to reduce the height of the step between the edge of the filter element 13 and the detergent box 11, which is beneficial to reduce the resistance of the detergent mixture solution in other areas of the detergent box 11 to flow to the filter element 13.

[0091] In some embodiments, please refer to Figure 2 and Figure 6 The filter element 13 is detachably connected to the detergent box 11.

[0092] Here, there are various specific ways in which the filter element 13 and the detergent box 11 can be detachably connected. For example, the filter element 13 and the detergent box 11 can be connected by snap-fit, plug-in or fastening.

[0093] It is understandable that after the detergent dispensing device 10 has been used for a period of time, the through holes 13a of the filter element 13 may become clogged, and there may also be detergent deposits in the detergent box 11.

[0094] In this embodiment, by detachably connecting the filter element 13 to the detergent box 11, it is convenient to disassemble and assemble the filter element 13 for cleaning, maintenance or replacement, thereby improving the user experience.

[0095] In some embodiments, please refer to Figure 4 The detergent box 11 is provided with a pull-out opening 11e, and the dispenser box 12 is pulled out and installed inside the detergent box 11 through the pull-out opening 11e. The filter element 13 is inclined along the direction of the pull-out of the dispenser box 12.

[0096] The filter element 13 is inclined along the direction in which the dispenser box 12 is pulled out, for example, the filter element 13 is inclined along the direction in which the dispenser box 12 is pushed into the detergent box 11.

[0097] The dispenser box 12 is at least partially pulled out of the detergent box 11 through the pull-out port 11e to the outside of the detergent box 11 for dispensing detergent into the detergent dispensing chamber 12a, and then the dispenser box 12 is pushed back into the detergent box 11.

[0098] For example, the first drain outlet 11c is located on the side of the filter element 13 near the pull-out port 11e.

[0099] In this embodiment, by tilting the filter element 13 along the direction of the dispenser box 12, the detergent mixture discharged from the detergent dispensing chamber 12a can flow along the downward tilted side of the filter element 13. During the flow, the dissolution of the detergent can be further promoted, the uniformity of the detergent and water mixing can be improved, thereby improving the utilization efficiency of the detergent.

[0100] In some embodiments, please refer to Figure 4 The upward tilt angle of filter element 13 is 3°-10°.

[0101] For example, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, etc.

[0102] It is understandable that, given the same length of the detergent dispensing device 10, the greater the upward tilt angle of the filter element 13, the more beneficial it is to increase the filtration area of ​​the filter element 13 and the flow rate of the detergent mixture along the filter element 13, thereby improving the filtration efficiency of the filter element 13; the smaller the upward tilt angle of the filter element 13, the more beneficial it is to reduce the size of the detergent dispensing device 10 in the height direction, thereby improving the structural compactness of the detergent dispensing device 10.

[0103] In this embodiment, by setting the upward tilt angle of the filter element 13 to 3°-10°, the filter element 13 can have a certain filtration efficiency, while also reducing the size of the detergent dispensing device 10 in the height direction and improving the structural compactness of the detergent dispensing device 10.

[0104] In some embodiments, please refer to Figure 6 The diameter of the via 13a is 2mm-3.5mm.

[0105] For example, the thicknesses are 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, etc.

[0106] In this embodiment, by setting the aperture of the through hole 13a to 2mm-3.5mm, the filter element 13 can have a better filtration effect, improving the situation where large particles of laundry detergent clog the first drain outlet 11c, while also improving the situation where the through hole 13a is clogged.

[0107] In some embodiments, please refer to Figure 6 The spacing between adjacent vias 13a is 3mm-10mm.

[0108] For example, the thicknesses are 3mm, 3.3mm, 3.5mm, 3.8mm, 4mm, 4.5mm, 5mm, 5.7mm, 6mm, 6.2mm, 6.5mm, 7mm, 7.2mm, 7.8mm, 8mm, 8.5mm, 8.8mm, 9mm, 9.5mm, 10mm, etc.

[0109] The spacing between adjacent vias 13a refers to the distance between any one via 13a and its nearest other via 13a, and is the distance between the centers of two adjacent vias 13a.

[0110] In this embodiment, by setting the spacing between adjacent through holes 13a to 3mm-10mm, the filter element 13 can have a certain filtration efficiency, while also facilitating the formation of the filter plate.

[0111] In some embodiments, please refer to Figure 1The garment handling device includes a drum assembly 20, which includes an inner drum (not shown). Exemplarily, the drum assembly 20 also includes an outer drum 21, within which the inner drum is rotatably disposed. The outer drum 21 holds water for washing clothes, and the inner drum holds the clothes. In this embodiment, the inner drum holds water through the outer drum 21; the inner drum can also be referred to as a perforated inner drum. In other embodiments, the inner drum holds water on its own; it can also be referred to as a non-perforated inner drum. The outer drum 21 may or may not be provided outside the inner drum.

[0112] It is understood that in some embodiments, the cylinder assembly 20 may only have an inner cylinder and not the outer cylinder 21 mentioned above. In this embodiment, the inner cylinder is a non-perforated inner cylinder that can hold water on its own.

[0113] For example, please refer to Figure 1 The garment processing equipment also includes a door (not shown), a housing (not shown), and a door seal ring 30 disposed on the front side of the bobbin assembly 20. The bobbin assembly 20 is disposed inside the housing. The housing has an opening communicating with the interior of the bobbin assembly 20, and the door is used to open or close the opening. The door seal ring 30 is used to seal the gap between the bobbin assembly 20 and the opening of the housing. When the door closes the opening, the door seals against the door seal ring 30, thereby forming a communicating space between the door, the door seal ring 30, and the interior of the bobbin assembly 20, which constitutes the garment processing chamber.

[0114] The door seal ring 30 has an installation opening, and the water outlet of the detergent dispensing device 10 passes through the installation opening of the door seal ring 30 and extends into the radial inner side of the door seal ring 30. This facilitates the dispensing of the detergent mixture into the garment processing chamber by the water outlet of the detergent dispensing device 10.
