This increases the functionality of the detergent dispensing device and adapts to different washing modes of the garment processing equipment. The different flow rates of the first and second sub-chambers eliminate the need to adjust the flow rate of a single chamber to control the detergent dispensing rate. Instead, the device can switch between activating the first and second sub-chambers. This structure is simple and reliable, offering greater reliability than the aforementioned flow rate adjustment schemes. Furthermore, the matching structure of the first and second sub-chambers with their corresponding flow rates facilitates continuous and uninterrupted liquid flow, resulting in a more uniform detergent mixture in the first detergent tank. This, in turn, promotes detergent dispensing and reduces residue. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0049] This application provides a detergent dispensing device; please refer to [link / reference]. Figure 1 and Figure 2 The detergent dispensing device includes a nozzle body assembly 100 and a dispenser box 200.

[0050] This application also provides a clothing processing device (not shown in the figure), which includes a clothing processing chamber and a detergent dispensing device as described in any embodiment of this application. The detergent dispensing device is used to dispense liquid containing detergent into the clothing processing chamber. It should be noted that the clothing processing device in this application includes, but is not limited to, top-loading washing machines, front-loading washing machines, washer-dryer combos, etc. This specification uses a top-loading washing machine as an example for description.

[0051] 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.

[0052] 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 inside 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.

[0053] Please see Figure 2 and Figure 4 and Figure 6 The nozzle body assembly 100 has a pull-out space 10b, a pull-out port, and a water inlet chamber. The water inlet chamber is located on the top side of the pull-out space 10b, and the water inlet chamber includes a first sub-chamber 10a-1 and a second sub-chamber 10a-2 that are not interconnected. That is, the liquid in the first sub-chamber 10a-1 will not flow into the second sub-chamber 10a-2, and the liquid in the second sub-chamber 10a-2 will not flow into the first sub-chamber 10a-1.

[0054] Please see Figure 1 , Figure 2 and Figure 4 The dispenser box 200 is removably disposed in the pull-out space 10b via a pull-out opening. The dispenser box 200 has at least one first detergent tank 201. The first sub-cavity 10a-1 and the second sub-cavity 10a-2 are both used to guide liquid to the same first detergent tank 201 of the dispenser box 200. The term "at least one" in this specification refers to a quantity that can be one or more, such as two, three, four, or more.

[0055] It should be noted that both the first sub-cavity 10a-1 and the second sub-cavity 10a-2 are used to guide the liquid to the same first detergent tank 201 of the dispenser box 200. This means that the same first detergent tank 201 can hold the liquid from both the first sub-cavity 10a-1 and the second sub-cavity 10a-2.

[0056] 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 first sub-cavity 10a-1 is divided into two parts, and both parts flow simultaneously into the two detergent tanks 201; the liquid in the second sub-cavity 10a-2 is also divided into two parts, and both parts 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 either the first sub-cavity 10a-1 or the second sub-cavity 10a-2, and the liquid can flow through both detergent tanks 201 to achieve detergent dispensing.

[0057] The first detergent tank 201 of the dispenser box 200 is used to hold detergent. The type of detergent is not limited; it can be fabric softener, laundry liquid, laundry powder, or detergent salt, etc. The user can pull out the dispenser box 200, add detergent to the first detergent tank 201, and then return the dispenser box 200 to its original position. The dispensing direction of the dispenser box 200 can be along the front-to-back direction of the garment handling equipment (direction v in the diagram).

[0058] The liquid in the first sub-cavity 10a-1 is introduced into the first detergent tank 201 of the dispenser box 200, where it mixes with the detergent to form a detergent mixture solution, and is then discharged from the dispenser box 200 into the garment processing chamber. Similarly, the liquid in the second sub-cavity 10a-2 is introduced into the first detergent tank 201 of the dispenser box 200, where it mixes with the detergent to form a detergent mixture solution, and is then discharged from the dispenser box 200 into the garment processing chamber. Exemplarily, the detergent mixture solution can be discharged into the garment processing chamber through a pull-out port.

[0059] Since the liquid in the first sub-cavity 10a-1 and the liquid in the second sub-cavity 10a-2 are both directed to the same first detergent tank 201, detergent can be dispensed by introducing water into either the first sub-cavity 10a-1 or the second sub-cavity 10a-2.

[0060] The flow rate of the first sub-cavity 10a-1 is greater than that of the second sub-cavity 10a-2. This flow rate refers to the amount of liquid flowing through the first sub-cavity 10a-1 or the second sub-cavity 10a-2 into the distributor box 200 per unit time. In other words, during the operation of the clothing processing equipment, the speed at which detergent is added through the first sub-cavity 10a-1 is greater than the speed at which detergent is added through the second sub-cavity 10a-2.

[0061] For example, faster detergent dosing is suitable for garment processing equipment that processes clothes through soaking, while slower detergent dosing is suitable for garment processing equipment that processes clothes through foam washing. Slower detergent dosing allows the detergent to dissolve fully and generate foam. Therefore, different detergent dosing speeds need to be matched to different washing modes of garment processing equipment.

[0062] The detergent dispensing device provided in this application embodiment can dispense detergent into the garment processing chamber through the first sub-chamber 10a-1 and the second sub-chamber 10a-2, and the dispensing speed is different. This increases the functionality of the detergent dispensing device and adapts to different washing modes of the garment processing equipment. The different flow rates of the first sub-chamber 10a-1 and the second sub-chamber 10a-2 eliminate the need to adjust the flow rate of a single chamber to control the detergent dispensing speed. Instead, the device can switch between activating the first sub-chamber 10a-1 and the second sub-chamber 10a-2. This structure is simple and reliable, and more reliable than the aforementioned flow rate adjustment scheme. Furthermore, the structure of the first sub-chamber 10a-1 and the second sub-chamber 10a-2 is matched to their corresponding flow rates, which helps maintain a continuous and uninterrupted liquid flow. This results in a more uniform formation of the detergent mixture in the first detergent tank 201, thereby facilitating detergent dispensing and reducing residue.

[0063] For example, such as Figure 2 As shown, there are two first detergent tanks 201, one for holding liquid detergents such as laundry liquid and the other for holding powder detergents such as laundry powder, to meet various user needs. When the first sub-cavity 10a-1 or the second sub-cavity 10a-2 is working, the detergent dispensing device can dispense a detergent mixture solution for cleaning clothes into the clothes processing cavity.

[0064] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 6 The water inlet chamber also includes a third sub-chamber 10a-3. The first sub-chamber 10a-1, the second sub-chamber 10a-2, and the third sub-chamber 10a-3 are not interconnected. The dispenser box 200 has at least one second detergent tank 202, and the third sub-chamber 10a-3 is used to guide liquid to at least one second detergent tank 202. The second detergent tank 202 is different from the first detergent tank and can hold different types of detergent.

[0065] The liquid in the third sub-cavity 10a-3 allows the detergent dispensing device to dispense detergent from the second detergent tank 202, thus 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 third sub-cavity 10a-3 after the clothes are cleaned to dispense fabric softener, making the clothes fluffy and soft.

[0066] There are no restrictions on how to make the flow rates of the first sub-cavity 10a-1 and the second sub-cavity 10a-2 different. For example, the water inlet structures of the first sub-cavity 10a-1 and the second sub-cavity 10a-2 can be designed differently, so that the amount of liquid entering the first sub-cavity 10a-1 and the second sub-cavity 10a-2 per unit time is different.

[0067] For example, in one embodiment, please refer to Figure 2 , Figure 4 and Figure 6 The nozzle assembly 100 includes a nozzle body 10 and a cover 20. The nozzle body 10 includes a water channel plate 11, and the cover 20 is disposed on the top side of the water channel plate 11, forming a first sub-cavity 10a-1 and a second sub-cavity 10a-2. That is, the first sub-cavity 10a-1 and the second sub-cavity 10a-2 are not pre-installed pipe structures, but are formed by assembling the water channel plate 11 and the cover 20. This arrangement facilitates the rational layout of the first sub-cavity 10a-1 and the second sub-cavity 10a-2, 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 form either the first sub-cavity 10a-1 or the second sub-cavity 10a-2.

[0068] Please see Figure 6 and Figure 10 The water circuit board 11 has at least one first through hole 11a-1 and at least one second through hole 11a-2. The first sub-cavity 10a-1 is connected to the pull-out space 10b through at least one first through hole 11a-1, and the second sub-cavity 10a-2 is connected to the pull-out space 10b through at least one second through hole 11a-2. It is understood that after the liquid from the first sub-cavity 10a-1 flows out into the pull-out space 10b, it falls into the first detergent tank 201, and after the liquid from the second 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 an additional drain pipe, saving space inside the detergent dispensing device.

[0069] In embodiments where there is one first through hole 11a-1 and one second through hole 11a-2, the flow area of ​​the first through hole 11a-1 is greater than the flow area of ​​the second through hole 11a-2, where the flow area is the effective cross-sectional area through which the fluid passes. In embodiments where there are multiple first through holes 11a-1 and / or multiple second through holes 11a-2, the total flow area of ​​the first through holes 11a-1 is greater than the total flow area of ​​the second through holes 11a-2, which is the sum of the multiple effective cross-sectional areas. Thus, the flow rate of the first sub-cavity 10a-1 is greater than the flow rate of the second sub-cavity 10a-2.

[0070] In embodiments with multiple first through holes 11a-1 and / or multiple second through holes 11a-2, the multiple first through holes 11a-1 and / or multiple second through holes 11a-2 can spray the detergent in the first detergent tank 201, which is beneficial to the uniform dissolution of the detergent.

[0071] For example, such as Figure 6 and Figure 10 As shown, the water circuit board 11 also has at least one third through hole 11a-3, and the third 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 third sub-cavity 10a-3 flows out into the pull-out space 10b, it falls into the second detergent tank 202.

[0072] In some embodiments, please refer to Figure 2 , Figure 12 and Figure 13 The nozzle body assembly 100 also includes a first water inlet 100a, a second water inlet 100b, and a valve assembly 40. The first water inlet 100a connects a water source to a first sub-cavity 10a-1, and the second water inlet 100b connects a water source to a second sub-cavity 10a-2. It should be noted that the first water inlet 100a, the second water inlet 100b (and the third water inlet 100c, the guiding water inlet 100d, and the directing water inlet 100e mentioned later) refer only to structures that facilitate the flow path of the liquid, and are not limited to pipe structures. The first water inlet 100a directs the liquid from the water source to the first sub-cavity 10a-1, and the second water inlet 100b directs the liquid from the water source to the second sub-cavity 10a-2. The dashed lines with arrows in the attached drawings indicate the direction of liquid flow for reference.

[0073] 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.

[0074] Valve assembly 40 is used to direct water source to the first water inlet 100a and close the second water inlet 100b; or, valve assembly 40 is used to direct water source to the second water inlet 100b and close the first water inlet 100a. That is, valve assembly 40 can control the opening and closing of the first water inlet 100a and the second water inlet 100b, that is, control whether the first sub-cavity 10a-1 introduces liquid into the first detergent tank 201, and control whether the second sub-cavity 10a-2 introduces liquid into the first detergent tank 201.

[0075] The valve assembly 40 may take the form of a single valve or a one-in-two-out valve, and the valve assembly 40 may include one or more valves. In this embodiment, the valve assembly 40 controls the opening and closing of the first water inlet 100a and the second water inlet 100b, thereby controlling the function of the detergent dispensing device.

[0076] In embodiments where the nozzle body assembly 100 has a third sub-cavity 10a-3, please refer to... Figure 6 , Figure 12 and Figure 13 The nozzle body assembly 100 also includes a water inlet passage 100d, which connects a water source and a third sub-cavity 10a-3, guiding liquid from the water source to the third sub-cavity 10a-3. In this embodiment, the valve assembly 40 is further configured to guide the water source to the water inlet passage 100d and close the first water inlet passage 100a and the second water inlet passage 100b; or, the valve assembly 40 is further configured to guide the water source to the first water inlet passage 100a and the second water inlet passage 100b and close the water inlet passage 100d.

[0077] For example, please refer to Figure 2 The valve assembly 40 includes a first valve 41 and a second valve 42. The first valve 41 is connected to the second valve 42. The first valve 41 is used to control the distribution of water source to the first water inlet 100a or the second valve 42. The second valve 42 is used to distribute the water source distributed by the first valve 41 to the second water inlet 100b or the diversion water inlet 100d.

[0078] For example, the garment processing equipment includes a control device, which is used to respond to the current working state of the garment processing equipment according to a preset program, and automatically control the opening and closing of the first water inlet channel 100a and the second water inlet channel 100b through the valve assembly 40. For example, in a specific embodiment, the garment processing equipment includes a control panel, which provides a window for human-machine interaction. The user can control the garment processing equipment through the control panel. The control panel has at least one function button. When the function button is pressed, the valve assembly 40 switches between directing water to the first water inlet channel 100a and closing the second water inlet channel 100b, and directing water to the second water inlet channel 100b and closing the first water inlet channel 100a. Through this function button, the user has more control over the garment processing equipment and can manually control the switching function of the detergent dispensing device.

[0079] For some embodiments, please refer to Figure 8 , Figure 9 , Figure 12 and Figure 13 The nozzle assembly 100 also includes a nozzle 50a, a water guide path 100e, and a third water inlet path 100c. The water guide path 100e collects at least a portion of the liquid discharged from the dispenser box 200 and directs the liquid to the nozzle 50a. The third water inlet path 100c connects a water source to the nozzle 50a, directing the liquid from the water source to the nozzle 50a. The nozzle 50a dispenses the mixture of the liquid from the third water inlet path 100c and the water guide path 100e into the garment processing chamber of the garment processing device. This dispensing refers to the liquid discharged from the nozzle 50a falling directly into the garment processing chamber due to its own inertia or gravity without needing an additional drainage structure.

[0080] It should be noted that, in some embodiments, the guide water path 100e can be used not only to collect the detergent mixture solution formed through the first sub-cavity 10a-1 discharged from the dispenser box 200, but also to collect the detergent mixture solution formed through the second sub-cavity 10a-2 discharged from the dispenser box 200.

[0081] Understandably, the liquid in the guide water path 100e is a detergent mixture solution. This detergent mixture solution mixes with the liquid in the third water inlet path 100c at the nozzle 50a, which helps to promote the dissolution of the detergent components and improve the foaming effect. The nozzle 50a then sprays the mixed liquid onto the clothes in the garment processing chamber, promoting contact between the detergent components and the surface of the clothes, which helps to improve the washing ratio of the garment processing equipment.

[0082] The liquid composition of the third water inlet 100c is not limited; it can be clean water or circulating water discharged from the circulation pump.

[0083] In some embodiments, please refer to Figure 12 and Figure 13The inlet end of the second water inlet 100b is connected to the inlet end of the third water inlet 100c, forming a common water inlet 100f. The common water inlet 100f simultaneously supplies water to both the second water inlet 100b and the third water inlet 100c. In other words, one end of the common water inlet 100f branches into two branches, one of which is part of the second water inlet 100b, and the other branch is part of the third water inlet 100c. When the common water inlet 100f is connected to a water source, both the second water inlet 100b and the third water inlet 100c are also connected to a water source.

[0084] In this embodiment, when the second water inlet 100b is connected to the water source, the third water inlet 100c is also connected to the water source. That is, after the second sub-cavity 10a-2 guides the liquid to the first detergent tank 201 to form a detergent mixture solution, the detergent mixture solution will flow to the nozzle 50a through the guide water channel 100e and mix with the liquid in the third water inlet 100c. Therefore, when the detergent dispensing device dispenses detergent through the second sub-cavity 10a-2, the detergent components dissolve better, which is more conducive to foaming, better adapts to the washing mode of the garment processing equipment, and improves the washing effect.

[0085] In some embodiments, the minimum flow cross-sectional area of ​​the second water inlet 100b is smaller than that of the third water inlet 100c. That is, the flow rate of the liquid from the water source directed to the second sub-cavity 10a-2 by the second water inlet 100b is less than the flow rate of the liquid from the water source directed to the nozzle 50a by the third water inlet 100c. This results in a more sufficient amount of liquid being directed to the nozzle 50a by the third water inlet 100c, which facilitates continuous impact mixing of the liquid in the guiding water channel 100e when the two liquids mix at the nozzle 50a, thereby improving the mixing and dissolving effect.

[0086] In some embodiments, please refer to Figures 3 to 5 The outlet of the third water inlet 100c faces the nozzle 50a. In this way, the liquid discharged from the outlet of the third water inlet 100c can drive the mixed liquid at the nozzle 50a to flow towards the nozzle 50a, and the water outlet shape of the nozzle 50a is similar to the water outlet shape of the third water inlet 100c.

[0087] 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 third water inlet 100c and is used to provide a circumferential velocity component to the liquid in the third water inlet 100c. The aforementioned provision of a circumferential velocity component means that the liquid in the third water inlet 100c, after passing through the turbulence structure 13711, has a non-zero velocity component in the circumferential direction of the third water inlet 100c, and the circumferential direction of the third water inlet 100c is perpendicular to the extension direction of the third water inlet 100c.

[0088] 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 guide water path 100e, improving mixing efficiency. It also enables the liquid at the outlet of the third water inlet path 100c to spread out in a roughly cone shape, resulting in a wider radiation range and better visual effect.

[0089] 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.

[0090] In some embodiments, please refer to Figure 4 and Figure 5 The outlet end of the third water inlet channel 100c is equipped with a narrowing section 1372a to increase the flow velocity at the outlet end of the third water inlet 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, resulting in a better mixing effect, and can also propel the mixed liquid at the nozzle 50a further, improving the spraying effect.

[0091] In some embodiments, please refer to Figure 4 , Figure 8 and Figure 9 At 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 liquid filtered by the filter zone 10c flows into the guide water path 100e. On the one hand, the filter zone 10c allows the liquid discharged from the distributor box 200 to pass through and enter the guide water path 100e. On the other hand, its filtration function divides the liquid discharged from the distributor 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 distributor box 200, i.e., the detergent mixture solution, and the air, increase the air content in the liquid, and promote detergent dissolution and foaming.

[0092] The filtration zone 10c also allows unfiltered liquid to be discharged through the pull-out port. When the liquid flow rate discharged from the dispenser box 200 is large, liquid that is not filtered in time by the filtration zone 10c can overflow through the pull-out port and enter the garment processing chamber, thus preventing the liquid flow in the detergent dispensing device from becoming clogged.

[0093] For example, the filter zone 10c has a plurality of densely arranged filter pores, such as Figure 9As shown.

[0094] In some embodiments, please refer to Figure 6 and Figure 8 The nozzle body 10 includes a first sidewall 12 and a side structure 13. The pull-out space 10b and the sidewall structure are located on opposite sides of the first sidewall 12 in a first direction. That is, the outer surface of the first sidewall 12 near the pull-out space 10b at least partially constitutes the inner wall of the pull-out space 10b, while the side structure 13 is located on the side of the first sidewall 12 away from the pull-out space 10b. In this way, the size of the nozzle body assembly 100 in directions other than the first direction can be reduced, making it easier to arrange the device in the workbench of the garment processing equipment. The first direction can be the left-right direction of the garment processing equipment.

[0095] A portion of the cover 20 extends to the top side of the side structure 13. The nozzle body assembly 100 includes a bottom cover 30, which is disposed on the bottom side of the nozzle body 10. The cover 20, side structure 13, and bottom cover 30 together enclose a portion of the guiding water passage 100e, the first water inlet passage 100a, and the second water inlet passage 100b. That is to say, the portion of the guiding water passage 100e, the first water inlet passage 100a, and the second water inlet passage 100b are not pre-installed pipe structures, but are formed after assembly by the cover 20, side structure 13, and bottom cover 30. This solution facilitates the rational arrangement of the first water inlet passage 100a, the second water inlet passage 100b, and the guiding water passage 100e, improving space utilization.

[0096] 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.

[0097] For example, the water inlet channel 100d is also enclosed by the cover 20, the side structure 13, and the bottom cover 30.

[0098] 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.

[0099] 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.

[0100] 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 second sub-cavity 10a-2. The first space 134a-1 defines a portion of the second water inlet passage 100b, and the second space 134a-2 defines a portion of the third water inlet passage 100c. That is, the second water inlet passage 100b and the third water inlet passage 100c are connected through the through hole 134a. When the third water inlet passage 100c is connected to a water source, it can also provide a water source for the second water inlet passage 100b. Figure 7 and Figure 12 As shown, a portion of the second space 134a-2 forms at least a portion of the public waterway 100f.

[0101] In this embodiment, no additional piping structure is required to set up the second water inlet 100b, which can save the space occupied by the second water inlet 100b.

[0102] 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.

[0103] For example, the flow cross-sectional area of ​​the through hole 134a is the minimum flow cross-sectional area of ​​the second water inlet 100b.

[0104] 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 flow guide structure disposed below the bottom wall portion 132. One end of the flow guide structure is connected to the first water outlet 132a, and the outlet of the other end is the outlet of the third water inlet 100c. The space within the flow guide structure defines a portion of the third water inlet 100c. The water outlet direction of the third water inlet 100c is approximately along the extension direction of the flow guide structure. The liquid in the second space 134a-2 enters the flow guide structure through the first water outlet 132a of the bottom wall portion 132 by immersion. The flow guide structure remains filled with liquid, so that the water outlet of the third water inlet 100c continuously sprays liquid without interruption.

[0105] For example, the flow cross-sectional area of ​​the first outlet 132a is the minimum flow cross-sectional area of ​​the third inlet 100c.

[0106] In some embodiments, please refer to Figures 3 to 5The 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.

[0107] 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 channel 100c. 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.

[0108] 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.

[0109] 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. The guide cavity 100e-1 defines a guide water path 100e. A guide 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 can be 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 guide water path 100e to the nozzle 50a.

[0110] 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.

[0111] 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 portion 135. The first enclosure 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 first 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 first 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.

[0112] 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 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 second channel 30a-2.

[0113] 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.

[0114] For example, please refer to Figure 1 and Figure 2 Both the first valve 41 and the second valve 42 can be installed on the support plate 131, and the support plate 131 can support the first valve 41 and the second valve 42 well.

[0115] For example, please refer to Figure 1 , Figure 2 and Figure 9The first valve 41 and the second valve 42 are arranged on the support plate portion 131 along the pull-out direction of the dispenser box 200, which saves space in the detergent dispensing device along the first direction and facilitates its placement within the workbench. For example, the detergent dispensing device also includes a hot water valve, which has sufficient space to be located on one side of the first valve 41 along the first direction.

[0116] 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.
