Description

Technical Field

[0001] This application relates to the field of clothing processing technology, and in particular to a detergent dispensing device and clothing processing equipment. Background Technology

[0002] In related technologies, rollers are installed on the dispenser box. The dispenser box is pulled out by the rollers rolling in the groove of the detergent box. It is hoped that the rolling contact between the rollers and the groove will reduce friction and improve the smoothness of the dispenser box. However, in actual use, when the dispenser is subjected to a force other than that in the pulling direction, the axial side of the roller is easily squeezed against the groove wall, which increases friction and can easily cause the dispenser to jam.

[0042] This application provides a detergent dispensing device 1000. The detergent dispensing device 1000 is used in clothing processing equipment.

[0043] Please see Figure 1 and Figure 2 The detergent dispensing device 1000 includes a dispenser box 20 and a detergent box 10.

[0044] This application also provides a garment processing device, including a drum assembly and a detergent dispensing device 1000 according to any embodiment of this application, the detergent dispensing device 1000 being used to provide detergent to the drum assembly.

[0045] The detergent dispenser 10 has an interconnected receiving cavity 10a and a pull-out opening 10b.

[0046] The dispenser box 20 is retractably disposed in the receiving cavity 10a and can be pulled out or pushed in through the pull-out port 10b. Here, pulling out can be a part of the dispenser box 20 being pulled out from the pull-out port 10b for the user to add detergent.

[0047] The type of detergent is not limited. It can be in liquid form, such as laundry detergent, disinfectant, perfume, fabric softener, etc., or it can be granular laundry powder, laundry pods, etc. There are no restrictions here.

[0048] The structure of the garment processing equipment is not limited. For example, it can be a vertical shaft type (the axis of the drum assembly is roughly vertical) or a roller type (the axis of the drum assembly is roughly horizontal).

[0049] The detergent dispenser 10 includes a first sidewall 12 facing the pull-out opening 10b.

[0050] The detergent dispenser 10 includes two second sidewalls 11, which are spaced apart along a first direction.

[0051] The first direction, the pull-out direction of the dispenser box 20, and the height direction of the detergent dispensing device 1000 are perpendicular to each other.

[0052] It should be noted that the pulling direction includes the pulling out direction and the pushing in direction, and the pulling out direction and the pushing in direction are parallel and opposite.

[0053] The detergent dispenser 10 also includes a lid 13 and a bottom wall 14, which are spaced apart along the height direction.

[0054] In some embodiments, the lid 13, bottom wall 14, first side wall 12, and two second side walls 11 enclose the aforementioned receiving cavity 10a.

[0055] In some embodiments, the detergent dispenser 10 is a one-piece structure, for example, it can be a single piece of plastic. A one-piece structure helps improve the structural strength and leak-proof performance of the detergent dispenser 10. Of course, the detergent dispenser 10 can also be assembled from multiple parts.

[0056] In some embodiments, the dispenser box 20 is a one-piece structure, for example, it can be a single piece of plastic. A one-piece structure helps improve the structural strength and leak-proof performance of the dispenser box 20. Of course, the dispenser box 20 can also be assembled from multiple components.

[0057] In some embodiments, the bottom surface of the receiving cavity 10a (the upper surface of the bottom wall 14) is used to guide the liquid flowing into the detergent dispenser 10 to the bottom edge of the pull-out port 10b, so that at least part of the liquid is discharged from the bottom edge of the pull-out port 10b, i.e., from the front edge of the bottom wall 14. That is, the pull-out port 10b also functions as a water outlet. In this embodiment, the clothes handling device is a vertical shaft type clothes handling device, such as a top-loading washing machine. An opening for loading clothes is formed on the top side of the drum assembly, and the pull-out port 10b is located above the opening. The liquid coming out of the pull-out port 10b can directly flow from the drum assembly below the pull-out port 10b.

[0058] In other embodiments, the detergent dispenser 10 is further provided with a mixing tank and a liquid outlet. The mixing tank is located below the dispenser box 20, and the liquid outlet is located on the bottom wall 14 of the mixing tank. Liquid in the detergent dispenser 10 is discharged from the liquid outlet and flows through a pipeline to the drum assembly. In this embodiment, the garment processing device is a drum-type garment processing device.

[0059] The detergent dispensing device 1000 also includes at least one guide rail assembly 30. See also... Figures 3 to 5 The guide rail assembly 30 includes a first guide rail 31.

[0060] The first guide rail 31 and the detergent dispenser 10 are separate components, with the first guide rail 31 fixed to the detergent dispenser 10. That is, the first guide rail 31 and the detergent dispenser 10 are two independent components connected together, and there is no relative movement between them.

[0061] In the detergent dispensing device 1000 of this application embodiment, the guide rail assembly 30 can be manufactured and assembled as a single component, facilitating mass production and reducing the manufacturing requirements for the detergent box 10 and the dispenser box 20. Furthermore, the guide rail assembly 30 guides the pull-out movement of the dispenser box 20. The fitting precision between the guide rails of the guide rail assembly 30 determines the movement accuracy and smoothness of the dispenser box 20. Manufacturing the guide rail assembly 30 as an independent component facilitates control over its manufacturing and assembly precision.

[0062] Please see Figure 4 and Figure 5 The first guide rail 31 has a columnar structure 311 at one end in the pulling direction and away from the pulling opening 10b. The first sidewall 12 has a through hole 12a. The columnar structure 311 is inserted into the through hole 12a and fixed in the through hole 12a along the pulling direction.

[0063] During assembly, the first guide rail 31 is inserted into the detergent box 10 along the pushing direction, and the columnar structure 311 is inserted into the through hole 12a. Then the columnar structure 311 is fixed in the through hole 12a.

[0064] In this embodiment, a columnar structure 311 is inserted into the through hole 12a. The insertion direction of the columnar structure 311 is consistent with the direction in which the first guide rail 31 is inserted into the detergent box 10. This makes assembly convenient and also facilitates fixing the columnar structure 311 into the through hole 12a from the outside of the detergent box 10.

[0065] The columnar structure 311 can be fixed to the through hole 12a in any way. For example, it can be fixed by non-removable connection methods such as fusion welding, ultrasonic welding, or bonding, or it can be fixed by removable connection methods such as screw connection.

[0066] In some embodiments, the detergent dispensing device 1000 includes a connector 50 that connects the first sidewall 12 and the columnar structure 311. The connector 50 may be, for example, a screw.

[0067] During assembly, the first guide rail 31 is inserted into the detergent dispenser 10 in the pushing direction, and the columnar structure 311 is inserted into the through hole 12a. Then, the connector 50 is fixed to the columnar structure 311 from the outside of the detergent dispenser 10, thus fixing the columnar structure 311 to the detergent dispenser 10 and achieving a fixed connection. When disassembly is required, the connector 50 is removed from the outside of the detergent dispenser 10, and the first guide rail 31 can be pulled out. Therefore, both installation and disassembly are relatively convenient.

[0068] In some embodiments, please refer to Figure 4 and Figure 5 The detergent dispensing device 1000 also includes a sealing ring 40, which is sleeved on the outer periphery of the columnar structure 311 and clamped between the first sidewall 12 and the first guide rail 31 in the pulling direction, or clamped between the outer surface of the first sidewall 12 and the connector in the pulling direction. The sealing ring 40 helps to improve the sealing performance of the mating joint between the columnar structure 311 and the through hole 12a, reducing the possibility of liquid leakage from the through hole 12a to the outside of the detergent box 10.

[0069] In some embodiments, a countersunk hole is provided on the inner surface of the first sidewall 12, which communicates with the through hole 12a, and the sealing ring 40 is accommodated in the countersunk hole. The countersunk hole is beneficial for limiting the position of the sealing ring 40.

[0070] In some embodiments, the first direction can be the left-right direction of the garment handling device, and the pulling direction can be the front-back direction of the garment handling device. The two second sidewalls 11 can be understood as the left and right sidewalls of the detergent box 10, and the first sidewall 12 can be understood as the rear sidewall of the detergent box 10.

[0071] The number of guide rail assemblies 30 can be one, two, or more.

[0072] In some embodiments, when the dispenser 20 moves to its limit position in the pushing direction (this limit position can be understood as the position of the dispenser box 20 when the detergent dispensing device can supply liquid to the drum assembly), the guide rail assembly 30 is disposed between the bottom wall 14 and the dispenser box 20, that is, the guide rail assembly 30 can be located below the dispenser box 20. Alternatively, the guide rail assembly 30 is disposed between the second side wall 11 and the dispenser box 20, that is, the guide rail assembly 30 is located on the left and / or right side of the dispenser box 20.

[0073] In this embodiment, the guide rail assembly 30 is described as being located in the left-right direction of the dispenser box 20. Specifically, there are at least two guide rail assemblies 30, with guide rail assemblies 30 respectively provided on opposite sides of the dispenser box 20 along the first direction. This helps to maintain the balance of force at both ends of the dispenser box 20 in the first direction and ensures smoothness of the pull-out process.

[0074] Of course, in other embodiments, the number of guide rail assemblies 30 may be one, with one guide rail assembly 30 located in the height direction between the dispenser box 20 and the bottom wall 14.

[0075] Guide rail assembly 30 includes a sliding-fit multi-stage guide rail; please refer to [link / reference]. Figures 3 to 5 The multi-stage guide rail includes at least the first guide rail 31 described above and the second guide rail 32 described below. That is, the guide rail assembly 30 has at least two stages.

[0076] The second guide rail 32 and the distributor box 20 are separate structures, and the second guide rail 32 is fixed to the distributor box 20. That is, the second guide rail 32 and the distributor box 20 are two independent components connected together, and there is no relative movement between them.

[0077] It should be noted that, in the first guide rail 31 and the second guide rail 32, the cross-sectional dimension of the first guide rail 31 perpendicular to the pulling direction may be larger than that of the second guide rail 32 perpendicular to the pulling direction, or the cross-sectional dimension of the first guide rail 31 perpendicular to the pulling direction may be smaller than that of the second guide rail 32 perpendicular to the pulling direction.

[0078] The material of the guide rail is not limited.

[0079] In some embodiments, the guide rail is a one-piece plastic structure. The guide rail can be a one-piece plastic structure obtained by single-color injection molding, multi-color injection molding, or compression molding. This allows the guide rail to have good structural strength, and the raw materials are inexpensive, which helps reduce costs. Furthermore, the plastic does not corrode even when in contact with water, allowing for long-term use.

[0080] Of course, in other embodiments, the guide rail can also be made of composite materials, metal materials, etc.

[0081] In some embodiments, two adjacent guide rails are in direct contact and friction is generated based on the contact area. In other words, there is no need to install ball bearings between two adjacent guide rails, which helps to simplify the structure and reduce costs.

[0082] The guide rail assembly 30 can have two, three, or even more stages.

[0083] In an embodiment where the guide rail assembly 30 has two levels, the two levels of guide rails are a first guide rail 31 and a second guide rail 32. In this embodiment, the first guide rail 31 may be nested inside the second guide rail 32. In this case, the second guide rail 32 can be referred to as the large guide rail, and the first guide rail 31 can be referred to as the small guide rail. Alternatively, the second guide rail 32 may be nested inside the first guide rail 31. In this case, the first guide rail 31 can be referred to as the large guide rail, and the second guide rail 32 can be referred to as the small guide rail.

[0084] In other embodiments, the guide rail assembly 30 further includes a third guide rail 33, which slidably connects the first guide rail 31 and the second guide rail 32. In this embodiment, the guide rail assembly 30 has three levels, with the third guide rail 33 nested between the first guide rail 31 and the second guide rail 32; the third guide rail 33 can be referred to as the middle guide rail. The third guide rail 33 can slide relative to the first guide rail 31 in the pull-out direction, and the second guide rail 32 can slide relative to the third guide rail 33 in the pull-out direction. The three-level guide rail allows the dispenser box 20 to have a larger pull-out stroke, which is beneficial for pulling the dispenser box 20 out a greater distance, making it easier for the user to add detergent to the dispenser box 20.

[0085] In some embodiments, please refer to Figure 3 and Figure 4 In the two adjacent guide rails, the outer guide rail includes a first convex hull 3c and a second convex hull 3d. The first convex hull 3c and the second convex hull 3d are arranged at intervals along the width direction of the guide rail assembly 30. The first convex hull 3c and the second convex hull 3d respectively slide in contact with the surfaces of the inner guide rail on opposite sides in the width direction. In this way, the first convex hull 3c and the second convex hull 3d constrain the inner guide rail in the width direction, and also help to reduce the contact area of ​​the two guide rails, reduce frictional resistance, and prevent jamming.

[0086] The width direction, thickness direction, and extension direction of the guide rail assembly 30 are perpendicular to each other. For example, in Figure 1 and Figure 2 In the illustrated embodiment, the width direction of the guide rail assembly 30 is consistent with the height direction of the detergent dispensing device 1000. In this case, the first convex 3c and the second convex 3d are arranged at intervals along the height direction of the detergent dispensing device 1000. When the guide rail assembly 30 is arranged between the dispenser box 20 and the bottom wall 14, its width direction is consistent with the first direction, i.e., the width direction is the left-right direction.

[0087] The number of the first convex hull 3c can be one, two, three, or more.

[0088] The number of second convex hull 3D can be one, two, three or more.

[0089] It should be noted that, taking a three-level guide rail as an example, the first guide rail 31, the third guide rail 33, and the second guide rail 32 are nested sequentially, with the third guide rail 33 nested within the first guide rail 31, and the second guide rail 32 nested within the second guide rail 32. Therefore, for the two adjacent guide rails, the first guide rail 31 is the outer guide rail, and the third guide rail 33 is the inner guide rail. Similarly, for the two adjacent guide rails, the third guide rail 33 is the outer guide rail, and the second guide rail 32 is the inner guide rail. In other words, the third guide rail 33 acts as both an outer and an inner guide rail. In this embodiment, the first guide rail 31 has a first convex hull 3c and a second convex hull 3d, and the third guide rail 33 also has a first convex hull 3c and a second convex hull 3d. The second guide rail 32 does not have a first convex hull 3c and a second convex hull 3d.

[0090] by Figure 1 and Figure 2 Taking the illustrated embodiment as an example, the first convex 3c of the first guide rail 31 is slidably engaged with the upper surface of the third guide rail 33, and the second convex 3d of the first guide rail 31 is slidably engaged with the lower surface of the third guide rail 33. The first convex 3c of the third guide rail 33 is slidably engaged with the upper surface of the second guide rail 32, and the second convex 3d of the third guide rail 33 is slidably engaged with the lower surface of the second guide rail 32.

[0091] In some embodiments, please refer to Figure 3 and Figure 4 In the two adjacent guide rails, the outer guide rail includes a plate 3a, and the first convex 3c is parallel to the plate 3a along the thickness direction of the plate 3a. Figure 1 and Figure 2 In one embodiment, the guide rails (with their thickness direction parallel to the first direction) are spaced apart, and the inner guide rails have a first rib structure 3e, which passes through the gap between the first convex 3c and the plate 3a. And / or, the second convex 3d and the plate 3a are spaced apart along the thickness direction of the plate 3a, and the guide rails inside the plate have a second rib structure 3f, which passes through the gap between the second convex 3d and the plate 3a.

[0092] Specifically, plate 3a and the first convex hull 3c constrain the first rib structure 3e in the thickness direction of plate 3a, so that the internal guide rail has essentially no degree of freedom of movement in the thickness direction of plate 3a. Plate 3a and the second convex hull 3d constrain the second rib structure 3f in the aforementioned thickness direction, so that the internal guide rail has essentially no degree of freedom of movement in the aforementioned thickness direction.

[0093] It should be noted that the same guide rail can have only the first rib structure 3e without the second rib structure 3f. Alternatively, it can have only the second rib structure 3f without the first rib structure 3e. It can also have both the first rib structure 3e and the second rib structure 3f simultaneously. This can improve the reliability of the internal guide rail's positioning and enhance the smoothness of sliding.

[0094] In some embodiments, in two adjacent guide rails, the outer guide rail includes a plate 3a and a surrounding edge 3b. The surrounding edge 3b extends along the edge of the plate 3a, and the plate 3a and the surrounding edge 3b together form an open groove 3k. The inner guide rail is slidably accommodated in the open groove 3k. The side of the open groove 3k away from the plate 3a is open. This facilitates both processing and assembly.

[0095] For example, the first convex hull 3c and the second convex hull 3d are disposed on the perimeter 3b. Specifically, the first convex hull 3c and the second convex hull 3d protrude from the surface of the perimeter 3b toward the open groove 3k.

[0096] The connection method between the second guide rail 32 and the dispenser box 20 is not limited. For example, in some embodiments, a detachable connection method using a hook and a slot is adopted. Specifically, the outer surface of the dispenser box 20 may have a hook, and the second guide rail 32 may have a slot; or, the outer surface of the dispenser box 20 may have a slot, but the slot does not connect to the interior of the dispenser box 20, and the second guide rail 32 may have a hook. The hook is inserted into the slot, thus achieving a quick connection between the two. In other embodiments, the second guide rail 32 and the dispenser box 20 may adopt a non-detachable connection method such as welding, ultrasonic welding, or bonding.

[0097] The connection method using hooks and slots is convenient and does not require screws, thus avoiding leakage from the distributor box 20.

[0098] It should be noted that a limit structure is set between two adjacent guide rails to prevent the guide rails from detaching from the adjacent guide rails in the extraction direction during normal sliding.

[0099] In some embodiments, please refer to Figure 5 The second guide rail 32 includes a spring arm 321 and a first limiting part 322 disposed on the spring arm 321. The guide rail adjacent to the second guide rail 32 includes a second limiting part 331 (see reference). Figure 4 The first limiting part 322 is used to cooperate with the second limiting part 331 in the withdrawal direction to limit the maximum sliding stroke of the second guide rail 32. The spring arm 321 is used to drive the first limiting part 322 away from the adjacent guide rail under the action of external force, so that the dispenser box 20 and the second guide rail 32 are separated from the detergent box 10.

[0100] It should be noted that in an embodiment where the guide rail assembly 30 has two levels, the guide rail adjacent to the second guide rail 31 is the first guide rail 31, and the second limiting part 331 is disposed on the first guide rail 31. In an embodiment where the guide rail assembly 30 has three levels, the guide rail adjacent to the first guide rail 31 is the third guide rail 33, and the second limiting part 331 is disposed on the third guide rail 33.

[0101] When it is not necessary for the dispenser box 20 to be completely detached from the detergent dispenser 10, the blocking action of the first limiting part 322 and the second limiting part 331 can prevent the dispenser box 20 from completely detaching from the detergent dispenser 10. When it is necessary to remove the dispenser box 20, for example, to replace or clean it, press the spring arm 321. The spring arm 321 moves the first limiting part 322, causing the first limiting part 322 to avoid the second limiting part 331. In this way, the second guide rail 32 and the dispenser box 20 can be completely pulled out. When it is necessary to put the dispenser box 20 back into the detergent dispenser 10, press the spring arm 321 to insert the second guide rail 32 into the adjacent guide rail, and then release the spring arm 321.

[0102] In some embodiments, the detergent dispenser 10 has a slot 11a that extends in the pull-out direction, and a first guide rail 31 is inserted into the slot 11a.

[0103] The slot 11a is used to limit the first guide rail 31 and prevent the first guide rail 31 from rotating in the slot 11a. Thus, when the first guide rail 31 is inserted into the slot 11a and before the connector 50 connects to the columnar structure 311, the first guide rail 31 has basically only the degree of freedom of movement in the pull-out direction in the slot 11a.

[0104] During assembly, the first guide rail 31 is inserted into the slot 11a in the pushing direction until the columnar structure 311 is inserted into the through hole 12a. Then, the columnar structure 311 and the first side wall 12 are connected by the connector 50. In this way, the movement of the first guide rail 31 in the pulling direction is restricted by the connector 50. At this time, the first guide rail 31 has no degree of freedom in any direction, thus fixing the first guide rail 31. In this way, the first guide rail 31 can be reliably fixed by the cooperation of the slot 11a and the connector 50. The structure is simple and easy to assemble and disassemble.

[0105] It should be noted that if the first guide rail 31 is disposed on the second side wall 11, then the slide groove 11a is formed on the second side wall 11. If the second guide rail 31 is disposed on the bottom wall 14, then the slide groove 11a is formed on the bottom wall 14.

[0106] In some embodiments, please refer to Figure 6The first sidewall 12 forms a limiting groove 12b, and the end of the first guide rail 31 away from the pull-out opening 10b is inserted into the limiting groove 12b. Since the first guide rail 31 is a long strip structure, the insertion stroke of the first guide rail 31 is relatively long during assembly. When the end of the first guide rail 31 is inserted into the limiting groove 12b, the limiting groove 12b plays a guiding and limiting role for the first guide rail 31, which is conducive to aligning the columnar structure 311 with the through hole 12a and inserting it into the through hole 12a.

[0107] The method of forming the limiting groove 12b is not limited; for example, please refer to [link / reference]. Figure 6 and Figure 7 A reinforcing rib 121 is formed on the inner surface of the first sidewall 12, and the reinforcing rib 121 and the second sidewall 11 form a limiting groove 12b.

[0108] In some embodiments, please refer to Figure 6 and Figure 7 The detergent dispenser 11 has a stop piece 111 located at one end of the slot 11a near the pull-out opening 10b. When the first guide rail 31 is inserted into place, the stop piece 111 is located on the side of the first guide rail 31 near the pull-out opening 10b, and is used to stop the first guide rail 31 in the pull-out direction. In this way, the first guide rail 31 can be prevented from dislodging from the slot 11a in the pull-out direction.

[0109] In some embodiments, the detergent dispensing device 1000 further includes a first magnetic structure and a second magnetic structure. The first magnetic structure is disposed in the detergent container 10, and the second magnetic structure is disposed in the dispenser container 20. At least when the dispenser container 20 moves to its limit position in the pushing direction (this limit position can be understood as the position of the dispenser container 20 when the detergent dispensing device can supply liquid to the cylinder assembly), the first and second magnetic structures magnetically engage. Magnetic engagement refers to the generation of a magnetic attraction force.

[0110] The location reference of the second magnetic structure Figure 2 The location of arrow A in the diagram.

[0111] It should be noted that in the first magnetic structure and the second magnetic structure, one of them can be a permanent magnet and the other can be a ferromagnetic component; or both can be permanent magnets.

[0112] When the dispenser box 20 is pushed in, as the second magnetic structure moves into the magnetic field range along with the dispenser box 20, the first and second magnetic structures generate a magnetic attraction. Based on this magnetic attraction, the dispenser box 20 can automatically move to the installed position. Thus, the user only needs to apply a small force to push the dispenser box 20 into the receiving cavity, and the first magnetic structure attracts and fixes the second magnetic structure. This helps to stabilize the dispenser box 20 in the installed position, preventing it from automatically exiting the receiving cavity and reducing the chance of the dispenser box 20 not moving into place or rebounding outward.

[0113] In some implementations, the first magnetic structure is encased in plastic; and / or, the second magnetic structure is encased in plastic. In this way, the first and second magnetic structures are not exposed to the external environment, do not come into contact with liquids, and are less prone to rusting, thus reducing the likelihood of magnetic attenuation due to rusting.

[0114] The aforementioned first magnetic structure / second magnetic structure being encapsulated in plastic refers to the plastic surrounding the first magnetic structure / second magnetic structure. For example, the first magnetic structure / second magnetic structure is placed in a mold, molten plastic is injected into the mold, and after the mold is opened, the plastic encapsulates the first magnetic structure / second magnetic structure.

[0115] In some embodiments, the first magnetic structure can be placed into the mold of the detergent box 10 during injection molding, and after injection molding, the first magnetic structure and the detergent box 10 become an integral structure.

[0116] In some embodiments, the second magnetic structure can be placed into the mold of the dispenser box 20 during injection molding, and after injection molding, the second magnetic structure and the dispenser box 20 become an integral structure.

[0117] Alternatively, the first magnetic structure can be wrapped with plastic before being connected to the detergent dispenser 10 by bonding, welding, or other methods. Similarly, the second magnetic structure can be wrapped with plastic before being connected to the dispenser dispenser 20 by bonding, welding, or other methods.

[0118] With the dispenser box 20 pushed into place, the relative positions of the first magnetic structure and the second magnetic structure are not limited. For example, they can be arranged in the front-back direction, the left-right direction, or the front-back direction.

[0119] Specifically, one or more of the following configurations can be used: A first magnetic structure is disposed on the left side wall of the detergent dispenser 10, and a second magnetic structure is disposed on the left end face of the dispenser box 20. A first magnetic structure is disposed on the right side wall of the detergent dispenser 10, and a second magnetic structure is disposed on the right end face of the dispenser box 20. A first magnetic structure is disposed on the rear side wall of the detergent dispenser 10, and a second magnetic structure is disposed on the rear end face of the dispenser box 20. A first magnetic structure is disposed on the lid 13 of the detergent dispenser 10, and a second magnetic structure is disposed on the upper surface of the dispenser box 20. A first magnetic structure is disposed on the bottom wall 14 of the detergent dispenser 10, and a second magnetic structure is disposed on the lower surface of the dispenser box 20.

[0120] For example, in some embodiments, a first magnetic structure is disposed on the side wall of the detergent dispenser 10 along the pull-out direction and away from the pull-out opening, and a second magnetic structure is disposed on the side of the dispenser dispenser 20 along the pull-out direction and facing the side wall. The first and second magnetic structures are arranged opposite each other along the pull-out direction and magnetically engage. In this way, the magnetic attraction force is approximately parallel to the pull-out direction, which can better hold the dispenser dispenser 20 in the pull-out direction.

[0121] The following description, in conjunction with the accompanying drawings, describes a specific embodiment of the detergent dispensing device 1000 of this application.

[0122] The detergent dispenser 10 has a pull-out opening 10b on the front side facing the garment handling equipment, and the dispenser box 20 can be pulled out and moved in the front-to-back direction within the detergent dispenser 10. The pull-out opening 10b faces the internal space of the garment handling equipment, and the liquid in the detergent dispenser 10 flows from the bottom surface of the receiving cavity 10a through the pull-out opening 10b to the drum assembly.

[0123] The dispenser box 20 is provided with guide rail assemblies 30 on both sides of the left and right directions of the garment processing equipment, and is slidably connected to the detergent box 10 through the guide rail assemblies 30.

[0124] The guide rail assembly 30 includes three guide rails: a first guide rail 31, a third guide rail 33, and a second guide rail 32. The third guide rail 33 is slidably connected to the first guide rail 31 and the second guide rail 32.

[0125] The first guide rail 31 is the large guide rail, the second guide rail 32 is the medium guide rail, and the third guide rail 33 is the small guide rail.

[0126] The first guide rail 31 and the third guide rail 33 have similar structures, both including a plate 3a, a surrounding edge 3b, a first convex hull 3c, and a second convex hull 3d. The third guide rail 33 passes through the open groove 3k of the first guide rail 31, and the second guide rail 32 passes through the open groove 3k of the third guide rail 33.

[0127] Please see Figure 5 The third guide rail 33 has a third limiting part 332, please refer to Figure 4The first guide rail 31 has a fourth limiting portion 312. When the third guide rail 33 moves in the extraction direction until the third limiting portion 332 and the fourth limiting portion 312 come into contact, the third guide rail 33 cannot continue to move in the extraction direction. It should be noted that the third limiting portion 332 and / or the fourth limiting portion 312 need to have appropriate elasticity so that during assembly, elastic deformation allows the third limiting portion 332 to pass over the fourth limiting portion 312, ensuring that the third guide rail 33 can be smoothly inserted into the first guide rail 31. For example, in this embodiment, please refer to... Figure 4 The fourth limiting part 312 is an elastic hook.

[0128] During assembly, a sealing ring 40 is fitted onto the columnar structure 311, and the first guide rail 31 is inserted into the slot 11a from front to back, ensuring that the columnar structure 311 is inserted into the through hole 12a. The columnar structure 311 is then fixed from the outside of the detergent box 10 using a connector 50, thus installing the first guide rail 31. The first guide rails 31 on both the left and right sides are installed in the same manner.

[0129] Next, insert the third guide rail 33 into the open groove 3k of the first guide rail 31 from front to back to complete the installation of the third guide rail 33. Complete the installation of the third guide rail 33 on the left and right sides in the same way.

[0130] The second guide rails 32 are fixed on the left and right sides of the dispenser box 20.

[0131] Insert the dispenser box 20 from front to back into the receiving cavity 10a through the pull-out port 10b. Align the second guide rail 32 with the third guide rail 33. Press the spring arm 321 and insert the second guide rail 32 into the open slide groove 3k of the third guide rail 33. In this way, the detergent dispensing device 1000 can be assembled.

[0132] It should be noted that when the guide rail assembly 30 adopts a two-level guide rail, the aforementioned third guide rail 33 can be omitted, and the second guide rail 32 can be inserted into the open groove 3k of the first guide rail 31.
