[0048] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0049] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0050] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0051] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0052] The first aspect of this application provides a garment processing apparatus. The garment processing apparatus includes a drum assembly and a detergent dispensing device as described in any embodiment of this application, the detergent dispensing device being used to supply detergent to the drum assembly.

[0053] The specific type of clothing processing equipment is not limited; for example, it can be a washing machine, a washer-dryer combo, etc.

[0054] For example, the laundry handling equipment includes a connecting pipe, a detergent dispensing device having a liquid outlet, and the connecting pipe connecting to the liquid outlet of the drum assembly. Thus, detergent in the detergent dispensing device can be dispensed into the drum assembly through the liquid outlet and the connecting pipe.

[0055] For example, the drum assembly has a clothes handling chamber and a clothes inlet for holding laundry, which can be clothes, shoes, carpets, etc. Users can put or take out laundry through the clothes inlet.

[0056] For example, the cylindrical assembly includes an outer tub and an inner tub, with the inner tub rotatably disposed within the outer tub. That is, the outer tub is fitted over the inner tub. The outer tub is used to hold water, and the inner tub is used to hold clothing; that is, the space within the inner tub forms a clothing handling chamber. In this embodiment, the inner tub holds water through the outer tub; the inner tub can also be referred to as a perforated inner tub.

[0057] A second aspect of this application provides a detergent dispensing device, which includes a detergent dispenser 1 (e.g., ...). Figure 1 (as shown) and dispenser box.

[0058] The detergent dispenser 1 includes a body 20 and a lid 10 disposed on the top side of the body 20. The body 20 and the lid 10 together enclose a receiving space.

[0059] For example, the dispenser box is retractably disposed within the box body 20. Specifically, it is located within the receiving space. Thus, the dispenser box is located below the box cover 10. The dispenser can be used to store detergent. The detergent can be laundry liquid, fabric softener, disinfectant, perfume, etc.

[0060] For example, the up and down direction is Figure 1The directions indicated include both top-down and bottom-up directions. The top-down direction is also the height direction.

[0061] In some embodiments, the cover 10 has a water inlet channel 11, a pressure relief water passage 15, a pressure relief hole 16, and one or more drain holes 12.

[0062] The water inlet channel 11 is used to connect with an external water source.

[0063] The pressure relief water passage 15 is connected to the water inlet channel 11 through the pressure relief hole 16. In this way, a portion of the liquid in the water inlet channel 11 enters the pressure relief water passage 15 through the pressure relief hole 16, which helps to maintain the liquid pressure in the water inlet channel 11.

[0064] A drain hole 12 is provided in the pressure relief water passage 15 to drain the liquid in the pressure relief water passage 15 to the housing 20. This helps to maintain the liquid pressure inside the housing cover 10.

[0065] In some embodiments, the detergent dispenser 1 further includes at least one splash-proof structure 30 disposed within the dispenser body 20 and located below at least one drain hole 12, for intercepting and / or dispersing liquid falling from the drain hole 12.

[0066] It should be noted that in an embodiment where there is one drain hole 12, there is one splash guard 30, which is located below the drain hole 12.

[0067] When there are multiple drainage holes 12, in some embodiments, the number of splash guards 30 can be the same as the number of drainage holes 12, such that multiple splash guards 30 are located below the corresponding drainage holes 12. In other embodiments, the number of splash guards 30 can be less than the number of drainage holes 12. In this embodiment, there can be one splash guard 30, located below one of the drainage holes 12. Alternatively, there can be multiple splash guards 30, each located below a portion of the drainage holes 12.

[0068] Specifically, the housing 20 has a mixing groove 21 located below the dispenser housing. The mixing groove 21 is part of the receiving space.

[0069] The anti-splash structure 30 is located inside the mixing tank 21. Liquid falling from the drain hole 12 above the anti-splash structure 30 flows through the anti-splash structure 30 and, after being acted upon by the anti-splash structure 30, flows to the bottom wall of the mixing tank 21.

[0070] The detergent dispensing device provided in this application embodiment has at least one anti-splash structure 30 that can disperse and buffer the liquid falling from at least one drain hole 12, so that the liquid falling from the drain hole 12 above the anti-splash structure 30 will not directly impact the bottom wall of the mixing tank 21, thereby reducing the degree to which the liquid falling from the drain hole 12 above the anti-splash structure 30 splashes in all directions due to direct impact on the bottom wall of the box 20.

[0071] It should be noted that in the relevant technology, the liquid falling vertically from the drain hole impacts the bottom wall of the mixing tank, causing the liquid inside the mixing tank to splash everywhere. Some of the liquid splashes onto the surface of the distributor box, which may cause the liquid to seep down the distributor box and onto its outer surface. Furthermore, some liquid, impacted by the liquid falling from the drain hole, splashes onto the side walls of the mixing tank and the surface of the distributor box, causing liquid to cling to these surfaces and forming residual water, thus creating watermarks. These watermarks are particularly noticeable when the mixing tank contains a detergent mixture.

[0072] The detergent dispensing device provided in this application embodiment helps to reduce the degree of liquid splashing from the drain hole 12 above the self-splash-proof structure 30. On the one hand, it helps to reduce the phenomenon that the liquid splashing from the drain hole 12 onto the surface of the dispenser box and then seeps into the outer surface of the dispenser box; on the other hand, it also helps to reduce the phenomenon of watermarks formed by the splashed liquid adhering to the side wall of the mixing tank and the surface of the dispenser box.

[0073] There are no restrictions on how the detergent is dispensed using the detergent dispensing device.

[0074] In some embodiments, the dispenser box has a first slot for containing detergent.

[0075] In some embodiments, the water inlet channel 11 includes a first water outlet area 111, and the bottom wall of the first water outlet area 111 is provided with at least one first water outlet hole 1111, which is used to guide liquid to a first groove below the cover 10.

[0076] Thus, the liquid sprayed from the first water outlet 1111 flows into the first tank, rinsing and dissolving the detergent in the first tank to form a detergent mixture. The detergent mixture then flows into the mixing tank 21 below the dispenser box. In other words, the user needs to add detergent to the first tank before each wash, and the amount of detergent added each time is sufficient for a single wash. This dispensing method can also be called manual dispensing.

[0077] For example, the drain hole 12 is located downstream of the first water outlet area 111. In this way, liquid that flows through the first water outlet area 111 but is not discharged is drained through the drain hole 12 to the housing 20, so as to minimize the impact of the drain hole 12 on the flow rate of liquid in the first water outlet area 111.

[0078] In some embodiments, the detergent dispensing device includes a pump 2, and the dispenser box includes a storage chamber. The pump 2 is used to draw detergent from the storage chamber. Thus, the pump 2 can be used to quantitatively draw detergent from the storage chamber, facilitating automatic detergent dispensing.

[0079] It should be noted that the storage chamber and the first tank are not connected. That is, the detergent in the first tank and the detergent in the storage chamber do not affect each other.

[0080] It is understood that the detergent dispensing device in the embodiments of this application may have both manual dispensing function and automatic dispensing function, or may have only one of the manual dispensing function and automatic dispensing function, and this is not limited here.

[0081] In some embodiments, such as Figure 2 and Figure 3 As shown, the water inlet channel 11 includes a mixing zone 113, where the liquid pump 2 draws detergent from the storage chamber and pumps it to the mixing zone 113. That is, the detergent drawn by the liquid pump 2 dissolves and mixes with the liquid in the water inlet channel 11 in the mixing zone 113 to form a detergent mixture.

[0082] It should be noted that the mixing zone 113 and the first outlet zone 111 are not connected; that is, the mixing zone 113 and the first outlet zone 111 are located on two different waterways. For ease of description, the waterway where the mixing zone 113 is located is named the first water flow channel, and the waterway where the first outlet zone 111 is located is named the second water flow channel. In other words, the inlet channel 11 includes the first water flow channel and the second water flow channel.

[0083] Please see Figure 3 In the diagram, S1 shows a portion of the second water flow channel, and S2 shows a portion of the first water flow channel. It should be noted that the arrows indicate the approximate flow direction of the liquid in the first and second water flow channels.

[0084] In some embodiments, please refer to Figure 3 A portion of the liquid in the second water flow channel flows into the mixing zone 113, i.e. Figure 3 The portion shown in S21 flows to the pressure relief water channel 15, while the other portion flows to the same channel. Figure 3As shown in the diagram S22, this allows the pressure relief water passage 15 to regulate the flow rate and pressure of the liquid flowing into the mixing zone 113, so that the flow rate and pressure of the liquid in the mixing zone 113 are maintained within a reasonable range, and excess liquid is discharged to the mixing tank 21 through the drain hole 12 of the pressure relief water passage 15.

[0085] For example, the lid 10 has a water outlet 14 for discharging the detergent mixture in the mixing zone 113, that is, the detergent mixture does not enter the box 20 or the mixing tank 21.

[0086] In some embodiments, the garment processing equipment includes a spray pipe 5.

[0087] Specifically, the outlet is used to connect to the spray pipe 5. In this embodiment, the detergent mixture in the mixing zone 113 flows to the spray pipe 5 through the outlet 14 and is sprayed out through the nozzle connected to the outlet end of the spray pipe 5.

[0088] For example, the garment handling equipment includes a door seal ring located at the front end of the bobbin assembly.

[0089] The nozzle connected to the outlet end of the spray pipe 5 is located on the door seal ring and faces the inside of the garment processing chamber to discharge liquid. In this way, the nozzle connected to the outlet end of the spray pipe 5 can directly spray the detergent mixture onto the clothes in the garment processing chamber, which is beneficial for the detergent components to contact the surface of the clothes and improve the washing ratio.

[0090] In some other embodiments, after the liquid pump 2 draws in the detergent, it can also discharge the detergent into the mixing tank 21. The detergent dissolves and mixes in the mixing tank 21 to form a detergent mixture, which is then discharged into the connecting pipe through the outlet 211.

[0091] It should be noted that, regardless of whether the dispensing is automatic or manual, the liquid passing through the pressure relief hole 16 and the drain hole 12 is clean water (e.g., tap water) without detergent.

[0092] For example, the detergent dispensing device includes a flushing pipe 3, which connects to the water inlet channel 11 and the inner cavity of the liquid pump 2, for guiding liquid into the inner cavity of the liquid pump 2 to clean the inner cavity of the liquid pump 2. This achieves cleaning of the inner cavity of the liquid pump 2 and reduces the likelihood of bacterial growth inside the liquid pump 2.

[0093] Specifically, when the pump 2 draws in detergent, the detergent enters the inner cavity and is then pumped out. It is understood that the liquid in the flushing line 3 enters the inner cavity of the pump 2 in a unidirectional manner; that is, the liquid in the inner cavity of the pump 2 will not flow back into the flushing line 3.

[0094] In some embodiments, the projection of one or more drain holes 12 onto a plane perpendicular to the height of the detergent dispenser 1 is outside the projected outline of the dispenser box. This minimizes the contact between liquid discharged from the drain holes 12 and the dispenser box, preventing liquid from leaking out through the gap between the dispenser box and the pull-out opening 22, and also ensuring that excessive liquid does not adhere to the outer wall of the dispenser box when the user pulls it out of the pull-out opening 22.

[0095] In some embodiments, in a plane orthographic projection perpendicular to the height of the detergent dispenser 1, the projection of at least one drain hole 12 lies within the projection of the corresponding at least one splash guard 30. That is, for a drain hole 12 with a splash guard 30 below it, the projection of the drain hole 12 lies within the projection of the corresponding splash guard 30. This ensures that liquid falling from the drain hole 12 above the splash guard 30 is intercepted and / or dispersed by the splash guard 30 as much as possible, further reducing the degree to which liquid falling from the drain hole 12 directly impacts the bottom wall of the dispenser 20 and splashes in all directions.

[0096] For example, the container 20 has a pull-out opening 22 through which the dispenser box can be pulled out. That is, the dispenser box is pulled out of the container 20 and can be removed from the container 20 through the pull-out opening 22. When detergent needs to be added to the dispenser box, the dispenser box is pulled out from the pull-out opening 22. After the detergent is added, the dispenser box is pushed back into the container 20.

[0097] For example, at least one drain hole 12 includes a first drain hole 121, and at least one splash guard 30 includes a first splash guard 32. In the orthographic projection of a plane perpendicular to the height direction of the detergent dispenser 1, the projection of the first drain hole 121 is located on the side of the dispenser dispenser away from the pull-out opening 22, and the first splash guard 32 is located below the first drain hole 121.

[0098] In this way, when some of the liquid in the water inlet channel 11 falls from the first drain hole 121, it can flush the detergent residue on the inner wall of the mixing tank 21, thus rinsing the inner wall of the mixing tank 21.

[0099] In some embodiments, the first splash-proof structure 32 includes a first portion 321 and a second portion 322, with the second portion 322 located on the side of the first portion 321 away from the pull-out opening 22, and the highest point of the second portion 322 being higher than the highest point of the first portion 321. In this embodiment, since the projection of the first drain hole 121 is located on the side of the dispenser box away from the pull-out opening 22, the first splash-proof structure 32 is at least partially located on the side of the dispenser box away from the pull-out opening, and the position of the first portion 321 is relatively low, which can provide clearance to the dispenser box.

[0100] In some embodiments, the housing 20 includes a first housing wall 23 facing the pull-out opening 22. The inner surface of the first housing wall 23 has a stepped surface 231 facing the housing cover 10. A first splash-proof structure 30 is disposed on the stepped surface 231. By providing the stepped surface 23, the first splash-proof structure 30 is supported, which helps to ensure that the splash-proof structure 30 is positioned directly below the drain hole 12.

[0101] For example, such as Figure 6 As shown, the detergent dispenser 1 includes a baffle 50 located at the edge of the stepped surface 231. The baffle 50 has a notch 51 for liquid to flow out from the stepped surface 231. In this embodiment, the notch 51 is used to concentrate the liquid flow out of the stepped surface 231, serving a guiding function. By forming notches 51 at different positions on the baffle 50, the liquid on the stepped surface 231 can be directed to different locations. It is understood that the position of the notch 51 can be set according to actual needs.

[0102] For example, in an embodiment where the detergent is pumped out by the pump 2 and discharged into the mixing tank 21, the notch 51 is positioned toward the detergent being placed into the mixing tank 21, so that the liquid on the step surface 231 flows into the detergent in the mixing tank 21, thereby having a certain flushing effect on the detergent and helping to reduce the amount of detergent remaining in the mixing tank 21.

[0103] Exemplarily, a portion of the first box wall 23 protrudes inward to form a guide portion 232, which is located below the baffle 50. A notch 51 guides liquid to the surface of the guide portion 232. The guide portion 232 extends downwardly from the center to both sides in a first direction, wherein the first direction, the pulling direction, and the height direction are perpendicular to each other. This allows the guide portion 232 to guide the liquid flowing out of the stepped surface 231 to both sides of the guide portion 232 along the first direction. For example, in an embodiment where the notch 51 is positioned towards where detergent is added to the mixing tank 21, the guide portion 232 also serves as a flow guide. The liquid discharged through the notch 51 is flushed by the guide portion 232, further reducing detergent residue in the mixing tank 21.

[0104] like Figure 5 As shown, the first direction is the direction indicated by v1, and the pulling direction is the direction indicated by v2.

[0105] Understandably, the specific form of the splash-proof structure 30 is not limited.

[0106] For example, in some embodiments, please refer to Figure 5The splash-proof structure 30 includes multiple protrusions 31 arranged along a horizontal plane. In this way, the multiple protrusions 31 can disperse the liquid falling from the drain hole 12.

[0107] It should be noted that the horizontal plane refers to the plane perpendicular to the height direction.

[0108] For example, the protrusions 31 extend toward the cover 10. This helps to increase the height of the protrusions 31, and the liquid falling from the drain hole 12 falls through the gap between the protrusions 31. After the liquid comes into contact with the bottom wall of the mixing tank 21, even if some liquid splashes, the splashed liquid can be basically blocked by the protrusions 31, so that the anti-splash structure 30 can better intercept and disperse the liquid falling from the drain hole 12.

[0109] In some embodiments, please refer to Figure 8 The distance d1 between two adjacent protrusions 31 does not exceed 5mm (millimeter). That is, d1≤5mm, for example, d1 can be 5mm, 4mm, 3mm, etc.

[0110] It should be noted that the distance between two adjacent protruding pillars 31 refers to the distance between the boundaries of the projections of the two adjacent protruding pillars 31 on the orthographic projection of a plane perpendicular to the height direction of the detergent dispenser 1, such as... Figure 8 The distance indicated by d1 in the middle.

[0111] By controlling the distance between two adjacent protrusions 31 within this range, the multiple protrusions 31 can effectively disperse the liquid falling from the drain hole 12.

[0112] The cross-sectional shape of the protrusion 31 is not limited; for example, the cross-sectional shape of the protrusion 31 can be circular. In other embodiments, the cross-sectional shape of the protrusion 31 can also be quadrilateral, pentagonal, hexagonal, etc.

[0113] In other embodiments, the splash-proof structure 30 includes a porous, water-permeable material.

[0114] It should be noted that porous permeable materials refer to materials with multiple permeable pores, such as sponges and textile fabrics.

[0115] In some other embodiments, the splash-proof structure 30 includes a mesh structure.

[0116] It should be noted that a mesh structure refers to a mesh structure formed by multiple strip structures arranged in a crisscross pattern, such as wire mesh or plastic mesh.

[0117] The assembly method of the splash-proof structure 30 is not limited. For example, in some embodiments, the housing 20 and the splash-proof structure 30 are integrally molded, for example, integrally injection molded. The integrally molded structure eliminates the assembly between the splash-proof structure 30 and the housing 20, and helps to improve the stability of the connection between the splash-proof structure 30 and the housing 20.

[0118] In the embodiment where the stepped surface 231 is formed, it is also convenient to form the first splash-proof structure 30 on the side of the stepped surface 23 facing the lid 10. That is, the stepped surface 231 facilitates the integral forming of the first splash-proof structure 30 and the box body 20.

[0119] In some embodiments, please refer to Figure 1 and Figure 2 The cover 10 includes a bottom plate 18 and a top plate 17. The top plate 17 is located on the top side of the top plate 18, and the two together form a water inlet channel 11 and a pressure relief water passage 15.

[0120] For example, the bottom cover 18 and the top cover 17 are separate structures.

[0121] It should be noted that the split structure refers to the bottom cover plate 18 and the top cover plate 17 being manufactured separately and then connected. The connection method between the top cover plate 17 and the bottom cover plate 18 is not limited. It can be a detachable connection or a non-detachable connection. Examples include ultrasonic welding, laser welding, screw connection, bonding, riveting, etc.

[0122] The split structure facilitates the inspection of the dimensions of structures such as the water inlet channel 11, the pressure relief water passage 15, the pressure relief hole 16, and the drain hole 12. This ensures that the dimensions of various structures inside the cover 10 meet the water inlet requirements before connecting the bottom cover plate 18 and the top cover plate 17, which helps improve the product manufacturing qualification rate.

[0123] For example, such as Figure 3 and Figure 4 As shown, the bottom plate 18 or the top plate 17 is formed with bridge pieces 184.

[0124] In some embodiments, the pressure relief hole 16 penetrates the bridge piece 184 along the height direction. Since the bottom cover plate 18 and the top cover plate 17 are separate structures, and the pressure relief hole 16 penetrates the bridge piece 184 along the height direction, when the bottom cover plate 18 and the top cover plate 17 are in a separated state, the opening direction of the pressure relief hole 16 faces outward, which facilitates the inspection of the cross-sectional dimensions of the pressure relief hole 16 to determine whether the cross-sectional dimensions of the pressure relief hole 16 meet the manufacturing requirements. That is, it helps to improve the inspection efficiency in the manufacturing process, thereby also helping to improve the manufacturing efficiency.

[0125] For example, in the orthographic projection on the horizontal plane, the bridge plate 184 is located in the pressure relief water passage 15. In this way, the bridge plate 184 will not affect the flow of liquid in the water inlet channel 11, that is, it will not affect the water inlet efficiency of the water inlet channel 11.

[0126] In some embodiments, one of the bottom cover plate 18 and the top cover plate 17 includes: a plate body 181, a first rib 182 and a second rib 183, wherein the first rib 182 and the second rib 183 form a pressure relief water passage 15 on the surface of the plate body 181.

[0127] like Figure 3 and Figure 4 As shown, plate 181, first rib 182, and second rib 183 are formed on bottom cover plate 18. It is understood that in other embodiments, plate 181, first rib 182, and second rib 183 may also be formed on top cover plate 17.

[0128] For example, bridge plate 184 is located between first rib plate 182 and second rib plate 183. In this way, bridge plate 184 is located in pressure relief water passage 15.

[0129] Exemplarily, the space between the bridge piece 184 and the plate 181 forms a bridge hole 185, which communicates with the water inlet channel 11. In this embodiment, please refer to... Figure 3 and Figure 4 Part of the liquid in the inlet channel 11 flows to the bridge hole 185, and then enters the pressure relief water passage 15 through the pressure relief hole 16. The bridge hole 185 can guide and buffer the liquid in the inlet channel 11.

[0130] In some embodiments, the number of drain holes 12 is multiple.

[0131] The plurality of drain holes 12 include a first drain hole 121 and a second drain hole 122, which are arranged at intervals along the fluid flow direction of the water inlet channel 11, and the second drain hole 122 is located upstream of the first drain hole 121. This helps to achieve step-by-step pressure relief.

[0132] For example, there are multiple splash-proof structures 30. The multiple splash-proof structures 30 are a first splash-proof structure 32 and a second splash-proof structure 33, with the first splash-proof structure 32 located below the first drain hole 121 and the second splash-proof structure 33 located below the second drain hole 122.

[0133] In some embodiments, please refer to Figure 5 and Figure 7 The detergent dispenser 1 also includes a defoaming unit 40, which is disposed inside the dispenser body 20 and located below the dispenser box. That is, the defoaming unit 40 is disposed inside the mixing tank 21.

[0134] It should be noted that the defoaming unit 40 refers to the structure used to reduce foam.

[0135] For example, the defoaming unit 40 includes a mounting shell 41 and a solid defoamer 42. The solid defoamer 42 is placed inside the mounting shell 41, that is, the mounting shell 41 is used to provide support for the solid defoamer 42. The shell wall of the mounting shell 41 is provided with a plurality of communication ports 43 so that the foam inside the box 20 comes into contact with the solid defoamer 42 through the communication ports 43.

[0136] Solid defoamer 42 refers to non-flowing defoamer 42, which can be in block form, granular form, etc., without limitation.

[0137] For example, the solid defoamer 42 can be selected as an organosilicon defoamer, or it can be selected as a defoamer with a special modified polysiloxane as the main defoaming component.

[0138] In some embodiments, the mounting housing 41 includes a detachably connected first housing and a second housing. When the solid defoamer 42 needs to be replaced, it is not necessary to replace the entire defoaming unit 40; simply disassemble the first and second housings and replace the old solid defoamer 42 with the new one.

[0139] For example, the housing 20 has a liquid outlet that communicates with the mixing tank 21, that is, the liquid outlet and the mixing tank 21 are interconnected. The liquid outlet is used to discharge the liquid in the mixing tank 21 to the outside of the housing 20, and then guide it to the connecting pipe.

[0140] It should be noted that during the operation of the drum assembly, a large amount of foam may be generated inside the assembly. This foam can easily overflow into the mixing tank through the connecting pipe. Additionally, the mixing of detergent and water in the mixing tank may also generate a significant amount of foam. If there is excessive foam in the mixing tank, it can easily overflow onto the outer surface of the dispenser box, resulting in a poor user experience. Furthermore, if a large amount of foam accumulates in the mixing tank, it can also obstruct the liquid inlet of the drum assembly.

[0141] The detergent dispensing device provided in this application embodiment has the following advantages: on the one hand, the foam in the mixing tank will break after contacting the defoaming unit, which can reduce the foam in the mixing tank and make it less likely for the foam in the mixing tank to overflow onto the outer surface of the clothing processing equipment, thereby improving the user experience; on the other hand, the defoaming unit can eliminate a large amount of foam accumulated in the mixing tank to a certain extent, which helps to reduce the obstruction of the foam to the liquid flow into the drum assembly and ensures the smooth flow of liquid into the drum assembly.

[0142] In some embodiments, when the dispenser box is removed from the box body 20, the pull-out opening 22 is used to retrieve and place the defoaming unit 40. This facilitates the removal of the defoaming unit 40 for maintenance, cleaning, or replacement.

[0143] In some embodiments, the defoaming unit 40 is located on the side of the liquid outlet near the pull-out port 22. This allows the defoaming unit 40 to reduce foam near the pull-out port 22, further reducing the likelihood of foam overflowing from the pull-out port 22 onto the outer surface of the dispenser box. It also facilitates the user in removing and placing the defoaming unit 40 from the pull-out port 22.
