To avoid unnecessary repetition, the various possible combinations of the specific technical features in this invention will not be described separately.

[0040] 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.

[0041] 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.

[0042] This application provides a detergent dispensing device for use in a garment processing device with a garment processing chamber. This application also provides a garment processing device (not shown in the figures), which includes a garment processing chamber and the detergent dispensing device from any embodiment of this application. The detergent dispensing component is used to dispense liquid containing detergent into the garment processing chamber. It should be noted that the garment processing devices in this application include, but are 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 for description.

[0043] 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.

[0044] Exemplarily, the garment handling equipment further includes a workbench disposed 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. In one embodiment, the workbench has a receiving space communicating with the garment handling chamber, the receiving space having an opening located on the inner side of the workbench, through which the 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.

[0045] The detergent dispensing device includes a first detergent tank 201, a water outlet, a spray nozzle 50a, a first water path 100a, a second water path 100b, a third water path 100d, and a water path switching assembly. The number of first detergent tanks can be one, two, or more. The first detergent tank 201 is used to hold detergent, which is not limited and can be laundry powder, liquid laundry detergent, detergent salt, or fabric softener, etc. Both the water outlet and the spray nozzle 50a are used to dispense liquid into the garment processing chamber; it is understood that the water outlet and the spray nozzle 50a are located in different positions.

[0046] The first water path 100a, the second water path 100b, and the third water path 100d are used to transport fluid and represent different liquid flow paths in the detergent dispensing device; they are not limited to tubular structures. The first water path 100a connects the water source and the outlet, while the second water path 100b and the third water path 100d both connect the water source and the nozzle 50a. That is, the first water path 100a transports liquid from the water source to the outlet, and the second water path 100b and the third water path 100d both transport liquid from the water source to the nozzle 50a. At the nozzle 50a, the liquids from the second water path 100b and the third water path 100d are mixed and sprayed out.

[0047] The form of water source is not limited; it can be a tap water pipe connected to the clothing processing equipment or the outlet pipe of the circulation pump of the clothing processing equipment.

[0048] The first water path 100a and the second water path 100b pass through the same first detergent tank 201, while the third water path 100d does not pass through either of the first detergent tanks 201. The liquid transported by the third water path 100d is the same as the liquid supplied by the water source. It should be noted that the first water path 100a and the second water path 100b passing through the same first detergent tank 201 means that the same first detergent tank 201 can hold liquid from either one of the water paths or liquid from the other water path.

[0049] Taking a scenario where there are two detergent tanks 201, and the first water path 100a and the second water path 100b flow through the same detergent tank 201, one detergent tank 201 can hold liquid detergent, such as laundry liquid, while the other detergent tank 201 can hold granular detergent, such as laundry powder or detergent granules. The liquid in the first water path 100a is divided into two parts, both of which flow simultaneously into the two detergent tanks 201; similarly, the liquid in the second water path 100b is divided into two parts, both of which flow simultaneously into 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, water can enter through either the first water path 100a or the second water path 100b, and the liquid can flow through both detergent tanks 201, thus achieving detergent dispensing.

[0050] The waterway switching component includes a first state and a second state.

[0051] Please see Figure 12 and Figure 13 In the first state, the water path switching component is used to distribute water to the first water path 100a and to shut down the second water path 100b and the third water path 100d. In this state, the detergent dispensing device carries the detergent from the first detergent tank 201 out through the liquid in the first water path 100a and dispenses it into the garment processing chamber.

[0052] Please see Figure 12 and Figure 13 In the second state, the water path is used to distribute water to the second water path 100b and the third water path 100d, and to cut off the first water path 100a. In this state, the detergent dispensing device carries the detergent from the first detergent tank 201 out through the liquid in the second water path 100b and mixes it with the liquid in the third water path 100d before dispensing it into the garment processing chamber. Unlike the first state, in the second state, due to the convergence and mixing of the two liquids, the detergent in the mixed liquid of the second water path 100b and the third water path 100d dissolves more fully, foams more easily, and has a better cleaning effect on the clothes. In other words, the first state and the second state can correspond to different washing functions of the garment processing equipment, and the first state and the second state can be switched by the water path switching component so that the detergent dispensing device can adapt to the washing function of the garment processing equipment.

[0053] The detergent dispensing device and clothing treatment equipment provided in this application embodiment are provided with a first water path 100a, a second water path 100b and a third water path 100d. The water path switching component has a first state in which the first water path 100a is open and a second state in which the second water path 100b and the third water path 100d are open, so as to change the degree of dissolution and mixing of detergent in the first detergent tank 201 and adapt to the current washing mode of the clothing treatment equipment.

[0054] For example, in one embodiment, in the first state, the garment processing device mainly washes the garments by soaking them in water; in the second state, the garment processing device washes the garments by causing the detergent components to generate a large amount of foam.

[0055] In some embodiments, the detergent dispensing device further includes a fourth water path 100c and at least one second detergent tank 202, meaning there may be two or more second detergent tanks 202. The second detergent tank 202 is used to hold detergent, which is different from the detergent held in the first detergent tank 201. The fourth water path 100c connects a water source and an outlet, transporting liquid from the water source to the outlet. The fourth water path 100c passes through the second detergent tanks 202, carrying away the detergent within them.

[0056] The water path switching assembly also includes a third state, in which the water path switching assembly is used to distribute water to the fourth water path 100c. In this state, the detergent dispensing device carries the detergent from the second detergent tank 202 out through the liquid in the fourth water path 100c and dispenses it into the garment processing chamber. In this embodiment, the detergent dispensing device switches between the first state (or the second state) and the third state through the water path switching assembly to dispense different detergents, so that the detergent dispensing device adapts to the washing function of the garment processing equipment.

[0057] For example, the second detergent tank 202 is used to hold fabric softener, and the water path switching component of the detergent dispensing device can switch to the third state after the clothes are cleaned to add fabric softener and make the clothes fluffy and soft.

[0058] It should be noted that the third water path 100d does not pass through any of the second detergent tanks 202, meaning that the liquid in the third water path 100d is the same as the water source it is connected to. For example, the third water path 100d is a clean water path, used to agitate the liquid in the second water path 100b, which helps to dilute the detergent and generate foam.

[0059] In some embodiments, please refer to Figure 2 , Figure 6 and Figure 12The water path switching assembly includes a first valve 41 and a second valve 42. The second valve 42 and the first water path 100a are respectively connected to the first valve 41, meaning that the liquid from the first valve 41 can enter the second valve 42 and the first water path 100a. The inlet end of the second water path 100b and the inlet end of the third water path 100d are connected to form a common water path 100f. The common water path 100f and the fourth water path 100c are both connected to the second valve 42. The first valve 41 selectively distributes water to either the second valve 42 or the first water path 100a, and the second valve 42 selectively distributes the water distributed by the first valve 41 to either the common water path 100f or the fourth water path 100c.

[0060] When the first valve 41 distributes water to the first water path 100a, the first water path 100a is open, while the common water path 100f and the fourth water path 100c connected to the second valve 42 are both closed. The switching component is in the first state.

[0061] When the first valve 41 distributes water to the second valve 42, and the second valve 42 then distributes water to the common water path 100f, the first water path 100a and the fourth water path 100c are shut off, while the second water path 100b and the third water path 100d, which constitute the common water path 100f, are both open. The water path switching component is in the second state.

[0062] When the first valve 41 distributes water to the second valve 42, and the second valve 42 then distributes water to the fourth water path 100c, the fourth water path 100c is open, while the first water path 100a, the second water path 100b which forms the common water path 100f, and the third water path 100d are closed. The water path switching component is in the third state.

[0063] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 4 The detergent dispensing device 100 includes a nozzle body assembly 100 and a dispenser box 200. A first detergent tank 201 is disposed in the dispenser box 200. The nozzle body assembly 100 has a pull-out space 10b and a pull-out opening, the pull-out opening being used for the dispenser box 200 to enter and exit the pull-out space 10b. For example, please refer to [reference needed]. Figure 2 The dispenser box 200 has a detergent dispensing port, allowing the user to dispense the detergent along the [unclear - possibly a specific direction or path]. Figure 2 As shown in the diagram, the container is pulled out in the v direction, detergent is added to the dispenser box 200 through the detergent dispensing port, and then pushed back into the dispenser box 200 in the pull-out space 10b along the v direction.

[0064] For example, a second detergent tank 202 is also provided in the dispenser box 200.

[0065] The water outlet forms part of the pull-out opening. That is, the water outlet connected to the first water path 100a and the fourth water path 100c is formed in the pull-out opening. The fluid from the first water path 100a and the fourth water path 100c enters the distributor box 200, carries the detergent into the pull-out space 10b, and is discharged through the pull-out opening and placed into the clothes processing chamber.

[0066] For example, the lower part of the pull-out opening forms a water outlet.

[0067] In some embodiments, please refer to Figure 2 and Figure 6 The nozzle body assembly 100 includes a cover 20, and the nozzle body 10 includes a water channel plate 1111. The cover 20 is disposed on the top side of the water channel plate 1111, and the two enclose a first sub-cavity 10a-1 and a second sub-cavity 10a-2 that are not interconnected. 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 first sub-cavity 10a-1 or the second sub-cavity 10a-2.

[0068] The first sub-cavity 10a-1 is located on the first water passage 100a, and the second sub-cavity 10a-2 is located on the second water passage 100b. The first sub-cavity 10a-1 and the second sub-cavity 10a-2 are used to guide water to the same first detergent tank 201 below. Exemplarily, the water passage plate 1111 of the nozzle body 10 has a first through hole 11a-1 and a second through hole 11a-2. The first sub-cavity 10a-1 is connected to the pull-out space 10b through the first through hole 11a-1, and the liquid in the first sub-cavity 10a-1 can enter the dispenser box 200 through the first through hole 11a-1; the second sub-cavity 10a-2 is connected to the pull-out space 10b through the second through hole 11a-2, and the liquid in the second sub-cavity 10a-2 can enter the dispenser box 200 through the second through hole 11a-2.

[0069] In this embodiment, a first sub-cavity 10a-1 and a second sub-cavity 10a-2 are opened between the water circuit plate 1111 of the nozzle body 10 and the cover 20, respectively defining the first water circuit 100a and the second water circuit 100b. This facilitates the guidance of the liquid from the water source to the first detergent tank 201 and also helps to save space, making the structure of the detergent dispensing device more compact.

[0070] In some embodiments, please refer to Figure 12 and Figure 13The cover 20 and the water channel plate 11 also enclose a third sub-cavity 10a-3. The first sub-cavity 10a-1, the second sub-cavity 10a-2, and the third sub-cavity 10a-3 are not interconnected. The third sub-cavity 10a-3 is located on the fourth water channel 100c and is used to guide liquid to the second detergent tank 202. Exemplarily, the water channel plate 111 of the nozzle body 10 has a third through hole 11a-3. The third sub-cavity 10a-3 is connected to the pull-out space 10b through the third through hole 11a-3, and the liquid in the third sub-cavity 10a-3 can enter the second detergent tank 202 through the third through hole 11a-3.

[0071] For example, in one embodiment, there are multiple first through holes 11a-1 and multiple second through holes 11a-2. The total cross-sectional area of ​​all first through holes 11a-1 is greater than the total cross-sectional area of ​​all second through holes 11a-2. The flow rate of liquid discharged from the distributor box 200 in the first state is greater than the flow rate of liquid discharged from the distributor box 200 when working in the second state.

[0072] For example, a portion of the worktable is integrally formed with at least a portion of the nozzle body 10. Since the portion of the worktable forms at least a portion of the nozzle body 10, the worktable structure is compact.

[0073] For example, a portion of the worktable and at least a portion of the lid 20 are integrally formed. The portion of the worktable forms at least a portion of the lid 20, thus the worktable structure is compact.

[0074] In some embodiments, the nozzle body 10 includes a first sidewall 12, and the nozzle body assembly 100 includes the 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, and a portion of the cover 20 extends to the top side of the side structure 13. Exemplarily, the pull-out direction of the dispenser box 200 is along the front-rear direction of the garment handling device, the first direction is along the left-right direction of the garment handling device, and the first sidewall 12 is located on the right side of the pull-out space 10b. This arrangement can fully utilize the internal space of the garment handling device.

[0075] In some embodiments, the nozzle body assembly 100 includes a bottom cover 30 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 portion of the second water passage 100b. Exemplarily, the bottom side of the nozzle body 10 and / or the side structure 13, together with the bottom cover 30, encloses a guide cavity 100e-1, which constitutes a portion of the second water passage 100b.

[0076] Please see Figure 4 and Figure 13At least a portion 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 distributor 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. In this embodiment, the solution filtered by the filter zone 10c enters the second water path 100b and is discharged through the nozzle 50a. That is, the fluid in the second water path 100b is discharged through the nozzle 50a, and the liquid in the first water path 100a and the fourth water path 100c flows through the pull-out space 10b and can be discharged through the outlet or partially discharged through the nozzle 50a.

[0077] 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 guide cavity 100e-1. 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.

[0078] 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.

[0079] In some embodiments, the water path switching component is located on the side structure 13 for easy installation.

[0080] In some embodiments, the 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 second sub-cavity 10a-2. The second space 134a-2 serves as at least a part of the common water passage 100f and at least a part of the third water passage 100d. That is, the liquid entering the second sub-cavity 10a-2 is drawn out from the liquid in the second space 134a-2, and the first space 134a-1 constitutes a part of the second water passage 100b. In this way, there is no need to arrange and connect additional tubular structures, saving the space occupied by the second water passage 100b and the third water passage 100d.

[0081] It should be noted that the bottom wall portion 132 is not limited to its location on the bottom side of the side structure 13.

[0082] In some embodiments, please refer to Figure 10and Figure 11 The bottom wall portion 132 corresponding to the second space 134a-2 is provided with a first water outlet 132a. The side structure 13 includes a guide structure 137 disposed below the bottom wall portion 132. One end of the guide structure 137 is connected to the first water outlet 132a, and the outlet of the other end is the water outlet of the third water passage 100d. The guide structure 137 extends into the guide cavity 100e-1.

[0083] In other words, the outlet of the third water passage 100d is led out from the second space 134a-2, and the second space 134a-2 constitutes part of the third water passage 100d. In this way, there is no need to arrange and connect additional tubular structures, saving the space occupied by the third water passage 100d.

[0084] In some embodiments, please refer to Figure 5 and Figure 11 The guiding structure 137 includes a split cylindrical portion 1371 and a nozzle portion 1372. The cylindrical portion 1371 connects the first water outlet 132a and the nozzle. Along the direction away from the cylindrical portion 1371, the nozzle bends towards the nozzle 50a so that the water outlet end of the third water path 100d faces the nozzle 50a. The liquid discharged from the water outlet end of the third water path 100d can drive the liquid of the second water path 100b to flow towards the nozzle 50a. The water outlet shape of the nozzle 50a is similar to the water outlet shape of the third water path 100d.

[0085] The space inside the nozzle has a narrowing section 1372a, and the flow cross-sectional area of ​​the narrowing section 1372a decreases along the water flow direction. The narrowing section 1372a increases the liquid flow velocity at the outlet of the third water channel 100d, which can increase the impact force of the liquid spray, achieve a better mixing effect, and drive the mixed liquid at the nozzle 50a to be sprayed further, thus improving the spraying effect.

[0086] For example, in one embodiment, please refer to Figure 5 and Figure 11 The detergent dispensing device includes a turbulence structure 13711. The turbulence structure 13711 is disposed within the guide structure 137. Specifically, the turbulence structure 13711 is located inside the cylindrical section 1371, upstream of the narrowing section 1372a. The turbulence structure 13711 provides a circumferential velocity component to the liquid in the third water path 100d. Providing a circumferential velocity component means that after the liquid in the third water path 100d passes through the turbulence structure 13711, the circumferential component of its velocity in the cylindrical section 1371 is not zero, and the circumferential direction of the cylindrical section 1371 is perpendicular to the extending direction of the cylindrical section 1371.

[0087] 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 at the nozzle 50a, improving mixing efficiency. It also enables the liquid at the outlet of the third water channel 100d to spread out in a roughly cone shape, resulting in a wider radiation range and better visual effect.

[0088] 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.

[0089] In some embodiments, please refer to Figure 12 and Figure 13 The bottom wall 132 of the second space 134a-2 is provided with a first water inlet 132b. The side structure 13 and the bottom cover 30 enclose a first water passage 30a-3, and 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 guiding structure 137, 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.

[0090] In some embodiments, please refer to Figure 9 , Figure 12 and Figure 13 The 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 space 134a-1. 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 channel 30a-1 and the first water inlet chamber 135a. The first water inlet chamber 135a connects to the first sub-chamber 10a-1. When the liquid in the first channel 30a-1 overflows, it enters the first water inlet chamber 135a through the first water outlet 131a, allowing the first water inlet chamber 135a to guide the liquid to the first sub-chamber 10a-1, and providing a large water pressure that is not easily interrupted. For example, the first valve 41 is connected to the water passage of the first channel 30a-1.

[0091] In some embodiments, please refer to Figure 6 and Figure 7 , Figure 12 and Figure 13The 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 third 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 third sub-cavity 10a-3, and providing high water pressure to prevent flow interruption. For example, the second valve 42 is connected to the water passage of the second channel 30a-2.

[0092] 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.

[0093] Both the first valve 41 and the second valve 42 can be installed on the support plate 131.

[0094] 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.

[0095] 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.

[0096] In some embodiments, the detergent dispensing device further includes a third valve (not shown), which is connected to a water source and the first 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 first water path 100a to the water source, and the third valve can also connect the first water path 100a to the 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 first 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 first water path 100a, thereby increasing the temperature at which the detergent is dispensed, promoting detergent dissolution, and improving the washing effect on clothes.

[0097] 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.

[0098] 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.
