[0038] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0039] In the description of the embodiments of this application, it should be noted that the terms "center," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0041] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature and the second feature are in direct contact, or that the first feature and the second feature are in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example that is included in at least one embodiment or example of the embodiments of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0043] This application provides a garment processing device, which includes a garment processing chamber, operation keys, a control device, and a detergent dispensing device. A schematic diagram of the detergent dispensing device can be found in [reference needed]. Figure 1 The detergent dispensing device is used to introduce liquid containing detergent into the garment processing chamber. It should be noted that the garment processing equipment in this application includes, but is not limited to, top-loading washing machines, front-loading washing machines, and washer-dryer combos; this specification uses a top-loading washing machine as an example.

[0044] The garment processing chamber (not shown) is used to contain garments to be processed. For example, the garment processing device includes a housing, a cylindrical assembly, and a cover assembly. The cylindrical assembly is disposed in the housing, and the interior of the cylindrical assembly constitutes at least part of the garment processing chamber. One side of the housing has a garment inlet. The cover assembly is used to open and close the garment inlet. Users can put and take out garments into the garment processing chamber through the garment inlet.

[0045] Please see Figures 1 to 4 ,as well as Figure 12 and Figure 13The detergent dispensing device includes a nozzle 50a, a first water path 100b, a second water path 100c, and a water path switching component. Both the first water path 100b and the second water path 100c are connected to the nozzle 50a. The liquid in the first water path 100b is a detergent mixture solution. The nozzle 50a is used to dispense the mixture of the first water path 100b and the second water path 100c into the garment processing chamber. The first water path 100b, the second water path 100c (and the third water path 100a and the fourth water path 100d mentioned later) refer only to the structures that facilitate the flow of liquid and are not limited to pipe structures.

[0046] Understandably, the detergent dispensing device can dispense detergent into the garment processing chamber through the nozzle 50a. The detergent mixture in the first water path 100b and the liquid in the second water path 100c are further mixed and impacted, which can promote the dissolution and foaming of the detergent components, resulting in a better cleaning effect on the clothes.

[0047] The water path switching component is used to cut off the first water path 100b and the second water path 100c, or to distribute the water source to the first water path 100b and the second water path 100c. In other words, the water path switching component controls the opening and closing of the first water path 100b and the second water path 100c.

[0048] The form of the water source is not limited; it can be a tap water pipe connected to the garment processing equipment or the outlet pipe of the garment processing equipment's circulation pump. After the liquid from the first water channel 100b is connected to the water source, it mixes with detergent to form a detergent mixture solution. The detergent mixture solution then mixes with the liquid from the second water channel 100c and enters the garment processing chamber, thereby realizing the dispensing of detergent.

[0049] The operation keys (not shown) and the water path switching component are both electrically connected to the control device. In response to the operation of the operation keys, the control device controls the water path switching component to either cut off the first water path 100b and the second water path 100c, or to distribute water to the first water path 100b and the second water path 100c. In other words, the user can actively operate the control device via the operation keys to switch the first water path 100b and the second water path 100c on and off.

[0050] For example, the operation key takes the form of a button, which can be pressed under external force to connect the internal circuit and generate an electrical signal. The control device responds according to the electrical signal. The aforementioned external force can be a user's pressing operation or a force applied to the operation key by the user through other structures. Of course, the operation key can also be in other forms such as a knob or a touch-sensitive capacitive button, and is not limited here.

[0051] Therefore, in this embodiment, the detergent dispensing device can dispense a sufficiently dissolved detergent mixture, resulting in better cleaning of the clothes. It also features operation buttons for users to actively select this washing mode, making it convenient for them to choose. Compared to embedding this washing mode into the washing program, this increases user flexibility. For example, users can use the operation buttons to start the mixed-liquid dispensing washing mode of the first water channel 100b and the second water channel 100c with one click, and then turn it off with one click once the dispensing amount and / or dispensing time meet the user's needs. This is particularly suitable for users' needs for spot cleaning and / or pre-washing of clothes.

[0052] like Figure 12 and Figure 13 As shown, the inlet end of the first water channel 100b and the inlet end of the second water channel 100c are connected to each other. In other words, the first water channel 100b and the second water channel 100c share the same inlet end and have a common water channel 100f. Thus, when the water source is distributed to the first water channel 100b, it is also distributed to the second water channel 100c. This structure is relatively simple and saves space.

[0053] It is understood that the control device can control the garment processing equipment through its internal preset program, so that the various components or functions of the garment processing equipment work in a predetermined sequence, including water intake, washing, drainage, spin-drying, etc. For example, in one embodiment, when the operation key is pressed, the original sequence of the garment processing equipment is inserted into a new node. At this node, the water path switching component controls the first water path 100b and the second water path 100c to be connected to the water source, and the detergent dispensing device dispenses detergent in the form of liquid mixed with the liquid in the first water path 100b and the second water path 100c.

[0054] In some embodiments, the garment handling equipment includes a workbench and a control panel, with the control panel disposed on the workbench. Exemplarily, the workbench is located on the top side of the housing, with a garment inlet formed on the inner side of the workbench, and a cover assembly disposed on the workbench. A detergent dispensing device is located inside the workbench.

[0055] The control panel provides a human-computer interaction window, allowing users to start, stop, or set parameters for the garment processing equipment. The operation keys are located on the control panel in a prominent position for easy user access.

[0056] In one embodiment, for example, the workbench has a receiving space communicating with the clothing processing chamber. The receiving space has an opening located inside the workbench, through which a detergent dispensing device is installed within the receiving space. In another embodiment, at least a portion of the workbench and the detergent dispensing device are integrally formed.

[0057] In some embodiments, please refer to Figure 4 and Figure 5 The detergent dispensing device includes a turbulence structure 13711, which is disposed in the second water channel 100c and is used to provide a circumferential velocity component to the liquid in the second water channel 100c. The aforementioned provision of a circumferential velocity component means that the liquid in the second water channel 100c, after passing through the turbulence structure 13711, has a non-zero velocity component in the circumferential direction of the second water channel 100c, and the circumferential direction of the second water channel 100c is perpendicular to the extension direction of the second water channel 100c.

[0058] After passing through the turbulent structure 13711, the liquid state changes and tends to spread out in the circumferential direction, forming multiple streams of liquid with different directions. This allows for better mixing with the liquid in the first water channel 100b, improving mixing efficiency. It also enables the liquid at the outlet of the second water channel 100c to spread out in a roughly cone shape, resulting in a wider radiation range and better visual effect.

[0059] For example, the turbulence structure 13711 includes one or more helical blades for guiding the helical motion of the liquid. A helical blade is a blade with a helical shape, extending in the helical direction. After passing through the helical blades, the liquid exhibits a helical motion with a circumferential velocity component. The helical blade structure is simple, provides good turbulence control for the liquid, and has low resistance, reducing energy loss as the liquid passes through.

[0060] In some embodiments, please refer to Figure 4 and Figure 5 The outlet end of the second water channel 100c is equipped with a narrowing section 1372a to increase the flow velocity at the outlet end of the second water channel 100c. It should be noted that the flow cross-sectional area of ​​the narrowing section 1372a decreases along the liquid flow direction. By limiting the flow cross-sectional area when the liquid is ejected, the narrowing section 1372a can increase the impact force of the ejected liquid, achieving a better mixing effect, and can also propel the mixed liquid at the nozzle 50a further, improving the spraying effect.

[0061] In some embodiments, please refer to Figure 2 and Figure 4 , Figure 12 and Figure 13 The detergent dispensing device further includes at least one first detergent tank 201, a third water channel 100a, and a water outlet for dispensing liquid into the garment processing chamber. The first detergent tank 201 is used to hold detergent. The type of detergent is not limited and can be fabric softener, laundry liquid, laundry powder, or detergent salt, etc. The term "at least one" in this specification refers to a quantity of one or more, such as two, three, four, or more.

[0062] For example, the detergent dispensing device includes a nozzle body assembly 100 and a dispenser box 200. The nozzle body assembly 100 has a pull-out space 10b and a pull-out opening. The dispenser box 200 has a first detergent tank 201 disposed inside it. The dispenser box 200 is pullable into the pull-out space 10b via the pull-out opening. The user can pull out the dispenser box 200 to add detergent to the first detergent tank 201, and then return the dispenser box 200. The pull-out direction of the dispenser box 200 can be along the front-to-back direction of the garment handling equipment (direction v in the figure).

[0063] Please see Figure 12 and Figure 13 The third water path 100a is connected to the water outlet. The third water path 100a and the first water path 100b pass through the same first detergent tank 201. The second water path 100c does not pass through any of the first detergent tanks 201.

[0064] It should be noted that the above-mentioned third water channel 100a and first water channel 100b pass through the same first detergent tank 201, which means that the same first detergent tank 201 can hold liquid from both the third water channel 100a and the first water channel 100b.

[0065] Taking two detergent tanks 201 as an example, one detergent tank 201 can hold liquid detergent, such as laundry liquid, and the other detergent tank 201 can hold granular detergent, such as laundry powder or detergent granules. The liquid in the third water path 100a is divided into two parts, and both parts flow simultaneously to the two detergent tanks 201; the liquid in the first water path 100b is also divided into two parts, and both parts flow simultaneously to the two detergent tanks 201. Users can add either laundry powder or laundry liquid at a time. Regardless of whether laundry powder or laundry liquid is added, as long as water enters either the third water path 100a or the first water path 100b, the liquid can flow through both detergent tanks 201, thus achieving detergent dispensing.

[0066] The second water path 100c does not pass through any of the first detergent tanks 201, and its liquid is the same as the liquid in the water source. For example, the liquid in the second water path 100c is clean water. The second water path 100c is a clean water path, which is beneficial for impacting and diluting the detergent mixture solution in the first water path 100b, and promoting foaming.

[0067] The water outlet and the nozzle 50a are two different locations for dispensing detergent mixture solution on the detergent dispensing device. For example, the lower part of the pull-out port constitutes the water outlet, that is, the detergent mixture solution formed by the third water channel 100a can enter the clothing processing chamber through the pull-out port.

[0068] In this embodiment, the detergent dispensing device has multiple water channels, which can enrich the means of dispensing detergent to match the washing mode of the clothing processing equipment.

[0069] In some implementations, the water path switching component includes a first state in which the water path switching component is used to distribute water to the third water path 100a and cut off the first water path 100b and the second water path 100c; and a second state in which the water path switching component is used to distribute water to the first water path 100b and the second water path 100c and cut off the third water path 100a.

[0070] The water path switching component switches between a first state and a second state, selectively distributing water to either the first water path 100b or the third water path 100a. Correspondingly, the detergent dispensing device dispenses detergent through different water paths. For example, dispensing detergent through the third water path 100a is suitable for garment processing equipment to process clothes in a soaking mode, while dispensing detergent through the first water path 100b is suitable for garment processing equipment to process clothes in a foam cleaning mode. The two liquid streams facilitate the full dissolution of the detergent and the generation of foam.

[0071] In some embodiments, please refer to Figure 2 , Figure 4 , Figure 12 and Figure 13 The detergent dispensing device also includes a fourth water channel 100d and at least one second detergent tank 202. The second detergent tank 202 is used to hold detergent. The second detergent tank 202 is different from the first washing machine tank and can hold different types of detergent.

[0072] The fourth water channel 100d connects to the water source and the outlet, and passes through the second detergent tank 202. The liquid in the fourth water channel 100d allows the detergent dispensing device to dispense detergent from the second detergent tank 202, enriching the functionality of the detergent dispensing device. For example, the second detergent tank 202 is used to hold fabric softener, and the detergent dispensing device can activate the fourth sub-cavity 10a-3 after the clothes are cleaned to add fabric softener, making the clothes fluffy and soft.

[0073] In some embodiments, the water path switching component further includes a third state in which the water path switching component is used to distribute water to the fourth water path 100d and shut down the first water path 100b and the second water path 100c. At this time, the detergent dispensing device can dispense detergent from the second detergent tank 202 into the laundry processing chamber.

[0074] In some embodiments, please refer to Figure 2 , Figure 12 and Figure 13The inlet of the first water path 100b and the inlet of the second water path 100c are connected to form a common water path 100f. The water path switching assembly includes a first valve 41 and a second valve 42. The second valve 42 and the third water path 100a are respectively connected to the first valve 41. The common water path 100f and the fourth water path 100d are both connected to the second valve 42. The first valve 41 selectively distributes water to the second valve 42 or the third water path 100a. The second valve 42 selectively distributes the water distributed by the first valve 41 to the common water path or the fourth water path 100d.

[0075] It is understood that the water source can be selectively allocated to the third water channel 100a, the first water channel 100b, or the fourth water channel 100d. The first valve 41 and the second valve 42 control the on / off state of the third water channel 100a, the first water channel 100b, and the fourth water channel 100d, thereby controlling the function of the detergent dispensing device. This approach is simple and reliable in structure. For example, the first valve 41 and the second valve 42 can be solenoid valves, which can be closed or opened under the action of an electrical signal from the control device.

[0076] In some embodiments, please refer to Figure 4 and Figure 6 The nozzle body assembly 100 includes a nozzle body 10 and a cover 20. The nozzle body 10 includes a water channel plate 11. The cover 20 is disposed on the top side of the water channel plate 11 and the two enclose a first sub-cavity 10a-2, a third sub-cavity 10a-1 and a fourth sub-cavity 10a-3 that are not interconnected.

[0077] The third sub-cavity 10a-1 is located on the third water passage 100a, and the first sub-cavity 10a-2 is located on the first water passage 100b. Liquid flows through the third water passage 100a, and liquid flows through the first water passage 100b through the first sub-cavity 10a-2. The third sub-cavity 10a-1 and the first sub-cavity 10a-2 respectively constitute a part of the third water passage 100a and the first water passage 100b. The third water passage 100a and the first water passage 100b are used to guide liquid to the same first detergent tank 201 below. For example, please refer to... Figure 6 and Figure 10 The water circuit board 11 has at least one first through hole 11a-2 and at least one third through hole 11a-1. The third sub-cavity 10a-1 is connected to the pull-out space 10b through at least one third through hole 11a-1, and the first sub-cavity 10a-2 is connected to the pull-out space 10b through at least one first through hole 11a-2. It is understood that after the liquid from the third sub-cavity 10a-1 flows out into the pull-out space 10b, it falls into the first detergent tank 201, and the liquid from the first sub-cavity 10a-2 flows out into the pull-out space 10b, it falls into the first detergent tank 201. This eliminates the need for additional drainage pipes and helps save space inside the detergent dispensing device.

[0078] The fourth sub-cavity 10a-3 is located on the fourth water passage 100d. Liquid from the fourth water passage 100d flows through the fourth sub-cavity 10a-3, which constitutes a part of the fourth water passage 100d. The fourth sub-cavity 10a-3 is used to guide the liquid to the lower second detergent tank 202. For example, as... Figure 6 and Figure 10 As shown, the water circuit board 11 also has at least one fourth through hole 11a-3, and the fourth sub-cavity 10a-3 is connected to the pull-out space 10b through at least one third through hole 11a-3. After the liquid in the fourth sub-cavity 10a-3 flows out into the pull-out space 10b, it falls into the second detergent tank 202.

[0079] It is understandable that the third sub-cavity 10a-1, the first sub-cavity 10a-2, and the fourth sub-cavity 10a-3 are not pre-installed pipe structures, but are assembled and enclosed by the water channel plate 11 and the cover 20. This scheme facilitates the rational arrangement of the third sub-cavity 10a-1, the first sub-cavity 10a-2, and the fourth sub-cavity 10a-3, improving space utilization. For example, a first water-dividing rib 111 is formed on one side of the water channel plate 11, and a second water-dividing rib 21 is formed on the side of the cover 20 near the water channel plate 11. The first water-dividing rib 111 and the second water-dividing rib 21 cooperate to enclose the third sub-cavity 10a-1, the first sub-cavity 10a-2, or the fourth sub-cavity 10a-3.

[0080] In some embodiments, please refer to Figure 4 , Figure 5 , Figure 8 and Figure 9 The detergent dispensing device includes a bottom cover 30, which is disposed on the bottom side of the nozzle body 10. The bottom cover 30 and the bottom wall of the pull-out space 10b together enclose a part of the first water passage 100b. At least a part of the bottom wall of the pull-out space 10b is provided with a filter zone 10c. The filter zone 10c is used to collect and filter the liquid discharged from the dispenser box 200, so that the solution filtered by the filter zone 10c flows to the space enclosed by the bottom wall and the bottom cover 30, and the solution that has not been filtered by the filter zone 10c is discharged through the pull-out port.

[0081] In this embodiment, the solution filtered by the filtration zone 10c enters the first water path 100b and is discharged through the nozzle 50a. That is, the fluid in the first water path 100b is discharged through the nozzle 50a, while the liquid in the third water path 100a and the fourth water path 100d flows through the draw-out space 10b and can be discharged through the outlet, i.e., the draw-out port, or partially discharged through the nozzle 50a.

[0082] In this embodiment, on the one hand, the filtration zone 10c allows the liquid discharged from the dispenser box 200 to pass through and enter the first water path 100b. On the other hand, its filtration function divides the liquid discharged from the dispenser box 200 into multiple fine liquid bundles, which can block incompletely dissolved detergent clumps, reduce the probability of downstream structure blockage, and also facilitate the contact between the liquid discharged from the dispenser box 200, i.e., the detergent mixture solution, and the air, thereby increasing the gas content in the liquid and promoting detergent dissolution and foaming.

[0083] Exemplary examples, in some embodiments, the nozzle 50a is disposed on the nozzle body 10. In other embodiments, please refer to... Figure 3 The nozzle 50a is located on the bottom cover 30, which facilitates the spraying of water towards the clothing treatment chamber.

[0084] In some embodiments, please refer to Figure 6 and Figure 7 The nozzle body 10 includes a first sidewall 12 and a side structure 13. The pull-out space 10b and the side structure 13 are located on opposite sides of the first sidewall 12 in a first direction. A portion of the cover 20 extends to the top side of the side structure 13. The water path switching assembly is disposed on the side structure 13.

[0085] The cover 20, side structure 13, and bottom cover 30 together enclose a portion of the third water channel 100a, a portion of the first water channel 100b, and a portion of the second water channel 100c. In other words, these portions are not pre-installed pipe structures, but are formed after assembly using the cover 20, side structure 13, and bottom cover 30. This arrangement facilitates the rational layout of the third water channel 100a, the first water channel 100b, and the second water channel 100c, improving space utilization.

[0086] For example, the water channel plate 11 is disposed on the top side of the nozzle body 10, that is, on the top side of the pull-out space 10b, and the water channel plate 11 is connected to the side of the first sidewall 12 near the pull-out space 10b.

[0087] For example, a portion of the workbench forms at least a portion of the bottom cover 30; or, a portion of the workbench forms at least a portion of the nozzle body 10; or, a portion of the workbench forms at least a portion of the box cover 20. That is, a portion of the workbench and at least a portion of the detergent dispensing device are integrally formed, thus making the structure of the garment handling equipment compact.

[0088] In some embodiments, please refer to Figures 11 to 13The side structure 13 includes a bottom wall portion 132, a side enclosure portion 133, and a partition wall 134. The partition wall 134 divides the area enclosed by the side enclosure portion 133 and the bottom wall portion 132 into a first space 134a-1 and a second space 134a-2. The partition wall 134 is provided with a through hole 134a, which connects the first space 134a-1 and the second space 134a-2. The first space 134a-1 is connected to the first sub-cavity 10a-2. The first space 134a-1 defines a portion of the first water passage 100b, a portion of the second space 134a-2 defines a portion of the first water passage 100b, and another portion defines a portion of the second water passage 100c. That is, the second water passage 100c is connected to the first water passage 100b through the second space 134a-2, and when the first water passage 100b is connected to a water source, it can also provide a water source for the second water passage 100c.

[0089] In this embodiment, there is no need to arrange additional piping structures to set up the first water path 100b and the second water path 100c, which can save the space occupied by the first water path 100b and the second water path 100c.

[0090] It should be noted that the bottom wall portion 132 is not limited to being located on the bottom side of the side structure 13.

[0091] In some embodiments, please refer to Figure 5 and Figure 11 The bottom wall portion 132 of the second space 134a-2 is provided with a first water outlet 132a. The side structure 13 includes a guide structure disposed below the bottom wall portion 132. One end of the guide structure is connected to the first water outlet 132a, and the outlet of the other end is the outlet of the second water passage 100c. The space within the guide structure defines a portion of the second water passage 100c. The water outlet direction of the second water passage 100c is approximately along the extension direction of the guide structure. The liquid in the second space 134a-2 enters the guide structure through the first water outlet 132a of the bottom wall portion 132 by immersion. The guide structure remains filled with liquid, so that the water outlet of the second water passage 100c continuously sprays liquid without interruption.

[0092] In some embodiments, please refer to Figures 3 to 5 The flow guiding structure includes a split cylindrical section 1371 and a nozzle section 1372. The cylindrical section 1371 connects the first water outlet 132a and the nozzle section 1372. The nozzle section 1372 bends towards the nozzle 50a in a direction away from the cylindrical section 1371 to spray water towards the nozzle 50a. The nozzle section 1372 is mounted on the cylindrical section 1371, and its outlet orientation can be adjusted according to the required water spray direction.

[0093] The space within the nozzle section 1372 forms a narrowed section 1372a, and the flow cross-sectional area of ​​the narrowed section 1372a decreases along the liquid flow direction. That is, the narrowed section 1372a is provided at the outlet end of the third water inlet. In this embodiment, the cylinder section 1371 and the nozzle section 1372 extend into the space between the bottom wall section 132 and the bottom cover 30. The liquid ejected from the outlet of the nozzle section 1372 has a suction effect on the surrounding liquid, which can promote mixing and foaming.

[0094] For example, a turbulent flow structure 13711 is provided inside the cylindrical section 1371, and the turbulent flow structure 13711 is located upstream of the narrowed section 1372a.

[0095] For example, please refer to Figure 4 and Figure 9 The bottom side of the nozzle body 10 and / or side structure 13, together with the bottom cover 30, encloses a guide cavity 100e-1, which defines a portion of the first water path 100b. A flow guiding structure extends into the guide cavity 100e-1, and the nozzle portion 1372 is spaced apart from the inner wall of the guide cavity 100e-1. It is understood that the detergent mixture discharged from the filter zone 10c enters the guide cavity 100e-1, is collected by the bottom cover 30, and flows along the first water path 100b to the nozzle 50a.

[0096] In some embodiments, please refer to Figures 7 to 9 The bottom wall portion 132 corresponding to the second space 134a-2 is provided with a first water inlet 132b. The bottom side of the side structure 13 and the bottom cover 30 define a water passage 30a-3. The first water inlet 132b connects the second space 134a-2 and the water passage 30a-3. After the liquid in the water passage 30a-3 overflows, it enters the second space 134a-2 through the first water inlet 132b, so that the second space 134a-2 can guide the liquid to the first space 134a-1 and the flow guiding structure, and has a large water pressure, making it difficult to interrupt the flow. For example, the second valve 42 is connected to the water passage 30a-3.

[0097] In some embodiments, please refer to Figure 8 , Figure 9 , Figure 12 and Figure 13The side structure 13 includes a support plate portion 131 and a first enclosure wall portion 135. The first enclosure wall portion 135 is connected to the first side wall 12 and together encloses a first water inlet cavity 135a. The support plate portion 131 and the bottom cover 30 together enclose a first channel 30a-1. The support plate portion 131 is provided with a first water outlet 131a, which connects the first water inlet cavity 135a and the first channel 30a-1. The first water inlet cavity 135a connects to a third sub-cavity 10a-1. When the liquid in the first channel 30a-1 overflows, it enters the first water inlet cavity 135a through the first water outlet 131a, allowing the first water inlet cavity 135a to guide the liquid to the third sub-cavity 10a-1, and providing a large water pressure that is not easily interrupted. For example, the first valve 41 is connected to the first channel 30a-1.

[0098] In some embodiments, please refer to Figure 8 , Figure 9 , Figure 12 and Figure 13 The side structure 13 also includes a second enclosure 136, which connects to the first side wall 12 and together encloses a second water inlet cavity 136a. A support plate 131 and a bottom cover 30 together enclose a second channel 30a-2. The support plate 131 is provided with a second water outlet 131b, which connects the second water inlet cavity 136a and the second channel 30a-2. The second water inlet cavity 136a connects to a fourth sub-cavity 10a-3. When the liquid in the second channel 30a-2 overflows, it enters the second water inlet cavity 136a through the second water outlet 131b, allowing the second water inlet cavity 136a to guide the liquid to the fourth sub-cavity 10a-3, and providing high water pressure to prevent flow interruption. For example, the second valve 42 is connected to the second channel 30a-2.

[0099] It should be noted that, for ease of identification and understanding, Figure 12 and Figure 13 The first inlet 132b, the first outlet 131a, and the second outlet 131b are highlighted by shaded areas, but have no other limiting meaning.

[0100] Please see Figure 1 and Figure 2 The first valve 41 and the second valve 42 are arranged along the pull-out direction of the dispenser box 200. This arrangement helps to reduce the size of the detergent dispensing device along the first direction. Since the nozzle body assembly 100 has reserved dimensions corresponding to the pull-out space 10b, the arrangement of the first valve 41 and the second valve 42 can reuse these dimensions without increasing the installation space occupied by the detergent dispensing device, thus facilitating the installation of the detergent dispensing device in the clothing processing equipment.

[0101] Specifically, the inlet and outlet of the first valve 41 are arranged along the pulling direction and are located on opposite sides of the first valve 41 in the pulling direction. The outlet of the first valve 41 is connected to the first channel 30a-1 and the second valve 42.

[0102] In some embodiments, the detergent dispensing device further includes a third valve (not shown), which connects to a water source and a third water path 100a. It is understood that the first valve 41 and the third valve are independent of each other; the first valve 41 can connect the third water path 100a to a water source, and the third valve can also connect the third water path 100a to a water source. The first valve 41 and the third valve are connected to different water sources, and the third valve can supply different liquids to the third water path 100a. For example, the third valve is a hot water valve, connected to a hot water source, which can supply hot water above room temperature to the third water path 100a, thereby increasing the temperature at which the detergent is dispensed, promoting detergent dissolution, and improving the washing effect on clothes.

[0103] The first valve 41 and the third valve are arranged along the first direction. Since the first valve 41 and the second valve 42 are arranged along the pull-out direction of the distributor box 200, the third valve can be conveniently arranged on the nozzle body assembly 100 along the first direction. In other words, the arrangement of the first valve 41 and the second valve 42 is conducive to the arrangement of the third valve on the nozzle body assembly 100.

[0104] In some embodiments, please refer to Figure 1 , Figure 6 and Figure 7 The inlet and outlet of the first valve 41 are arranged along the pull-out direction of the distributor box 200 and are located on opposite sides of the first valve 41. This facilitates the connection of the first valve 41 to a water source. For example, when the water source is an external tap water pipe, the first valve 41 can be easily tightened onto the tap water pipe.

[0105] The various embodiments / implementations provided in this application can be combined with each other without creating contradictions.

[0106] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
