[0004] In related technologies, clothing processing equipment includes a clothing processing drum, a detergent dispenser, and piping, with the piping connecting the detergent dispenser and the clothing processing drum. During washing, external water is introduced into the detergent dispenser to form a detergent mixture, which then flows through the piping into the clothing processing drum, thus adding detergent. However, the detergent often does not dissolve completely and mixes unevenly with the water, resulting in insufficient detergent utilization, poor cleaning performance, and a negative impact on the user experience. Summary of the Invention

[0005] In view of this, the embodiments of this application aim to provide a detergent dispensing device and a clothing treatment device that can effectively promote detergent dissolution and improve the cleaning effect of clothing.

[0011] The detergent dispensing device includes a first pipe section and a second pipe section. The detergent supply component has a water passage. The first pipe section is connected to a water source and the inlet of the water passage. The second pipe section is connected to the outlet of the water passage. The space within the first pipe section, the water passage, and the space within the second pipe section together define at least a portion of the second water path.

[0012] In some embodiments, the detergent dispensing device further includes a turbulence structure disposed in the second water channel for providing a circumferential velocity component to the fluid in the second water channel.

[0013] In some embodiments, a narrowing section is provided at the end of the second water passage to increase the flow velocity at the outlet of the second water passage.

[0014] In some embodiments, the detergent supply assembly has a detergent dispensing chamber and a mixing chamber, the first water path flows through the detergent dispensing chamber and the first drain outlet; the mixing chamber is used to receive the detergent mixture solution discharged from the detergent dispensing chamber, and the first drain outlet is disposed on the chamber wall of the mixing chamber.

[0015] In some embodiments, the detergent dispensing device includes a nozzle unit, the liquid outlet water path is located within the nozzle unit, the outlet ends of the first water path and the second water path are located within the nozzle unit, and the outlet end of one of the first water path or the second water path is provided with a flow guiding channel for guiding the fluid toward the outlet end of the other.

[0016] In some embodiments, the cross-sectional area of ​​the flow guide channel gradually increases along the direction of fluid movement.

[0017] In some embodiments, the flow velocity at the outlet of the first water path is less than the flow velocity at the outlet of the second water path, and the guide channel is disposed at the outlet of the first water path.

[0018] In some embodiments, the nozzle unit includes a first connector tube, a second connector tube, and a housing. The housing has a spray nozzle. The first connector tube and the second connector tube are respectively connected to the housing. The first water path flows through the first connector tube, and the second water path flows through the second connector tube. The fluids in the first water path and the second water path converge in the housing and are sprayed out through the spray nozzle.

[0019] This application embodiment also provides a garment processing device, including:

[0021] And the detergent dispensing device described in any embodiment of this application;

[0022] The outlet end of the liquid outlet path is connected to the clothing processing chamber.

[0023] The detergent dispensing device provided in this application embodiment allows the second water path to allow water from the source to flow into the outlet water path, where it merges with the fluid from the first water path. The two fluids collide and mix in the outlet water path, promoting detergent dissolution and improving the washing ratio. The detergent supply component has at least one branch for fluid flow, allowing water from the source to pass through the detergent supply component and enter the outlet water path along the second water path. Therefore, the detergent supply component can be either a structure that supplies detergent to form a detergent mixture solution or a container with a flow channel forming the second water path. This increases the reusability of structural components and saves space in the detergent dispensing device. Attached Figure Description

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

[0039] Please refer to Figures 1 to 10. This application embodiment provides a detergent dispensing device 100, including a detergent supply component 30, a liquid outlet water path, a first water path 40A, and a second water path 50A. The dashed lines with arrows in the figures indicate the direction of fluid flow.

[0040] This application also provides a clothing processing device, including a clothing processing chamber and a detergent dispensing device 100 as described in any embodiment of this application, wherein the outlet end of the liquid outlet path is connected to the clothing processing chamber.

[0041] The garment processing chamber is used to accommodate garments to be processed. In one embodiment, for example, the garment processing device includes a cylindrical assembly 10 and a door seal ring 60. The door seal ring 60 is disposed on the front side of the cylindrical assembly 10, and the communicating space formed between the interior of the cylindrical assembly 10 and the radially inner side of the door seal ring 60 constitutes the garment processing chamber.

[0042] The detergent supply assembly 30 has a first drain outlet 30b for discharging the detergent mixture solution, that is, the detergent mixture solution flows out from the first drain outlet 30b.

[0043] It should be noted that the detergent mixture mentioned in this instruction manual is for ease of description only, referring to a mixture containing dissolved detergent. Its mass percentage concentration is not limited, nor is it limited to the complete dissolution of the detergent. The form of the detergent is not limited; it can be powdered laundry detergent, liquid laundry detergent, or fabric softener, etc.

[0044] Please refer to Figures 2 and 10. The liquid outlet water path has an inlet and an outlet. The first water path 40A and the second water path 50A are used to transport fluid. The first water path 40A connects to the water source, the first drain outlet 30b, and the inlet of the liquid outlet water path. The fluid in the first water path 40A is a detergent mixture solution. It can be understood that the detergent mixture solution discharged from the first drain outlet 30b enters the first water path 40A, forming a detergent mixture solution in the first water path 40A, which is then circulated into the liquid outlet water path.

[0045] Please refer to Figures 3 and 10. The second water path 50A connects the water source and the inlet of the liquid outlet path, and a portion of the second water path 50A is disposed within the detergent supply assembly 30. The second water path 50A allows the fluid from the water source to flow into the liquid outlet path, where it merges with the fluid from the first water path 40A. The two fluids collide and mix in the liquid outlet path, promoting detergent dissolution and improving the washing ratio. The mixed fluid is then discharged into the garment processing chamber through the outlet of the liquid outlet path, contacting the garments to be processed.

[0046] The fluid in the second water path 50A is not limited; it can be tap water or a fluid containing detergent. For example, in some embodiments, the garment processing device further includes a circulation pump, and the inlet of the second water path 50A is connected to the outlet of the circulation pump. In other embodiments, the garment processing device further includes an inlet valve 90, and the inlet of the second water path 50A is connected to the first outlet 90a of the inlet valve 90.

[0047] It should be noted that the liquid outlet path refers to the flow path from the mixing point of the first water path 40A and the second water path 50A to the point where the mixed fluid leaves the liquid outlet path. The inlet of the liquid outlet path refers to the point where the fluid in the first water path 40A leaves the first water path 40A and enters the liquid outlet path, and the point where the fluid in the second water path 50A leaves the second water path 50A and enters the liquid outlet path. The outlet of the liquid outlet path refers to the point where the fluid in the liquid outlet path leaves the liquid outlet path.

[0048] In this embodiment, the first water path 40A and the second water path 50A refer only to the flow path of the fluid and are not limited to a pipe structure. At least a portion of the second water path 50A is disposed within the detergent supply assembly 30, meaning that there is at least one path for fluid flow inside the detergent supply assembly 30. The fluid in the second water path 50A flows through the detergent supply assembly 30. It should be noted that the path of the second water path 50A through the detergent supply assembly 30 is not connected to the detergent flow path within the detergent supply assembly 30. This improves the reusability of the detergent supply assembly 30, saves space occupied by the detergent dispensing device 100, and facilitates the arrangement of the detergent dispensing device 100 in the garment processing equipment.

[0049] For example, in one embodiment, the detergent supply component 30 includes a detergent box and a dispenser box. The dispenser box is removably disposed inside the detergent box, and the user can add detergent by pulling out the dispenser box. The second water channel 50A may be partially disposed in the detergent box.

[0050] For example, in one embodiment, a portion of the first water path 40A is disposed within the detergent supply assembly 30, which has a detergent dispensing chamber 30A (e.g., formed within a dispenser box). Fluid from the first water path 40A flows through the detergent dispensing chamber 30A, mixes with detergent, and forms a detergent mixture solution, which is then discharged through the first drain outlet 30b. Therefore, in this embodiment, both the first water path 40A and the second water path 50A pass through the detergent supply assembly 30 simultaneously, resulting in a compact structure and further improving space utilization.

[0051] A portion of the second water passage 50A is disposed within the detergent supply assembly 30, including but not limited to the following two types.

[0052] In the first embodiment, the detergent dispensing device 100 includes a first tube, one end of which is connected to a water source and the other end is used to guide fluid to an outlet water path. The space inside the first tube defines at least a portion of a second water path. The first tube passes through the detergent supply assembly 30.

[0053] Understandably, the first pipe can be a single pipe or a pipe composed of multiple pipe segments joined together, connecting the water source to the liquid outlet path, allowing the fluid from the water source to enter the liquid outlet path. The first pipe passes through the detergent supply assembly 30, indicating that the first pipe is independent of the detergent supply assembly 30 and can be detachably assembled onto it. In this way, the detergent dispensing device 100 has a simple structure and high reliability, and the first water path 40A has fewer components, which can reduce fluid leakage at the component connections.

[0054] In the second embodiment, referring to Figures 2 and 3, the detergent dispensing device 100 includes a first pipe section 501 and a second pipe section 502. The detergent supply assembly 30 has a water passage (not shown). The first pipe section 501 connects to a water source and the inlet of the water passage, and the second pipe section 502 connects to the outlet of the water passage and the inlet of the liquid outlet path. The space within the first pipe section 501, the water passage, and the space within the second pipe section 502 together define at least a portion of the second water path 50A.

[0055] Understandably, the water source flows through the first pipe section 501, the water passage, and the second pipe section 502 into the nozzle unit 200. The water passage is formed inside the detergent supply component 30, with its two ends connected to the first pipe section 501 and the second pipe section 502, respectively. It can be seen that the water passage is integrated with the detergent supply component 30, thus increasing the integration of the detergent supply component 30, which is beneficial to the manufacturing of the detergent supply component 30 and the assembly of the detergent dispensing device 100.

[0056] In some embodiments, referring to Figures 9 and 10, the detergent dispensing device 100 further includes a turbulence structure 21 disposed in the second water channel 50A for providing a circumferential velocity component to the fluid in the second water channel 50A.

[0057] The aforementioned circumferential velocity component refers to the fluid in the second water channel 50A after passing through the turbulent structure 21, whose velocity direction has a non-zero component in the circumferential direction of the second water channel 50A, and the circumferential direction of the second water channel 50A is perpendicular to the extension direction of the second water channel 50A.

[0058] In this embodiment, the turbulent structure 21 allows some of the fluid to have both a circumferential velocity and a forward flow velocity, so some of the fluid moves in a roughly spiral motion. When the fluid is ejected from the outlet of the second water channel 50A, it facilitates the conical diffusion of the fluid, resulting in a wider radiation range and better visual effect.

[0059] For example, the turbulent structure 21 includes one or more helical blades that divide at least a portion of the length of the second waterway 50A into multiple sub-channels.

[0060] The term "multiple" refers to the number of blades, which can be two, three, or more. In other words, the number of spiral heads is not less than two, and it does not limit the number of spiral turns.

[0061] After passing through the helical blades, the fluid exhibits a spiral motion. The helical blades have a simple structure, a good turbulence effect on the fluid, and low resistance, thus reducing energy loss when the fluid passes through.

[0062] In some embodiments, please refer to Figures 9 and 10, the end of the second water channel 50A is provided with a narrowing section 22 to increase the flow velocity at the outlet of the second water channel 50A.

[0063] For example, in some embodiments, the end of the narrowed section 22 forms the outlet of the second water passage 50A. That is, the fluid of the second water passage 50A is ejected from the end of the narrowed section 22. In other embodiments, the end of the narrowed section 22 is also connected to a constant diameter section and / or an expanded diameter section, which form the outlet of the second water passage 50A.

[0064] It should be noted that, along the direction of fluid movement, the flow area of ​​the fluid decreases in the aforementioned narrowing section 22, remains basically unchanged in the aforementioned constant diameter section, and increases in the aforementioned widening section.

[0065] The narrowing section 22 increases the impact force of the fluid by limiting the flow area when the fluid is ejected, resulting in a greater impact force on the fluid at the outlet of the first water channel 40A and achieving a better mixing effect.

[0066] Meanwhile, the narrowing section 22 gives the outlet of the second water channel 50A a large jet velocity, which can generate a significant negative pressure in a relatively large area. This negative pressure causes the fluid at the outlet of the first water channel 40A to be drawn in and mixed with the fluid in the second water channel 50A, thus improving the mixing and foaming effect.

[0067] In some embodiments, referring to Figures 5, 6, and 7, the detergent supply assembly 30 has a detergent dispensing chamber 30A and a mixing chamber 30B. A first water path 40A flows through the detergent mixing chamber 30B and a first drain outlet 30b. The mixing chamber 30B is used to collect the detergent mixture discharged from the detergent dispensing chamber 30A, and the first drain outlet 30b is disposed on the chamber wall of the mixing chamber 30B.

[0068] The detergent mixture discharged from the detergent dispensing chamber 30A can directly enter the mixing chamber 30B and be discharged through the first drain port 30b on the wall of the mixing chamber 30B. This eliminates the need for an additional drain pipe, allowing for a more compact structure of the detergent supply assembly 30. For example, the mixing chamber 30B is located below the detergent dispensing chamber 30A, and the detergent mixture flows downwards into the mixing chamber 30B under gravity.

[0069] In some embodiments, referring to FIG4, the detergent supply assembly 30 includes a filter structure 302 disposed on the top side of the mixing chamber 30B. The filter structure 302 has a plurality of filter holes that communicate with the mixing chamber 30B and are used to filter the detergent mixture solution discharged from the detergent dispensing chamber 30A.

[0070] It should be noted that the detergent mixture discharged from the detergent dispensing chamber 30A will flow onto the filter structure 302, enter the mixing chamber 30B through the filter holes, and then be discharged from the first drain outlet 30b at the mixing chamber 30B. That is, the filter holes are used to filter the detergent mixture discharged from the detergent dispensing chamber 30A.

[0071] It is understandable that when the detergent added to the detergent dispensing chamber 30A is in powder form such as laundry powder, clumping may occur due to factors such as a humid storage environment or insufficient dissolution during dispensing. This may result in lumps of laundry powder remaining in the detergent mixture discharged from the detergent dispensing chamber 30A. The filtration function of the filter structure 302 can effectively prevent these lumps from entering the mixing chamber 30B, minimizing blockage of downstream pipes. Furthermore, the detergent mixture discharged from the detergent dispensing chamber 30A can flush away the lumps of laundry powder blocked by the filter structure 302, thus promoting dissolution.

[0072] In some embodiments, please refer to Figures 5, 6 and 7, the detergent supply assembly 30 also has an overflow chamber 30C and a second drain outlet 30a. The overflow chamber 30C is used to collect the detergent mixture overflowing from the mixing chamber 30B, and the second drain outlet 30a is used to discharge the detergent mixture in the overflow chamber 30C into the detergent dispensing device 100.

[0073] Understandably, when the water level in mixing chamber 30B is not higher than the overflow level, the fluid in mixing chamber 30B is discharged from the first drain outlet 30b; when the water level in mixing chamber 30B is higher than the overflow level, the excess fluid overflows into overflow chamber 30C and is discharged from the second drain outlet 30a. Therefore, overflow chamber 30C and the second drain outlet 30a serve a safety protection function.

[0074] For example, the garment processing device also includes a water inlet pipe 70, which is connected to a second drain outlet 30a to guide the fluid discharged from the second drain outlet 30a into the garment processing chamber. Thus, when the mixing chamber 30B overflows, the second drain outlet 30a can also serve as an auxiliary water inlet.

[0075] In some embodiments, referring to FIG7, the detergent supply assembly 30 has a spacer structure 301, with an overflow chamber 30C and a mixing chamber 30B located on opposite sides of the spacer structure 301, i.e., the spacer structure 301 separates the overflow chamber 30C and the mixing chamber 30B. One end of the filter structure 302 extends above the spacer structure 301, and the filter structure 302 is inclined downward from the direction away from the overflow chamber 30C to the direction near the overflow chamber 30C.

[0076] In this embodiment, when the flow rate discharged from the detergent dispensing chamber 30A is large, the detergent mixture that cannot flow through the filter holes in time can flow into the overflow chamber 30C along the upper surface of the filter structure 302, providing a safety protection function. Furthermore, detergent clumps intercepted by the filter structure 302 can move along the upper surface of the filter structure 302 into the overflow chamber 30C, thereby minimizing the risk of detergent clumps clogging the filter holes on the filter structure 302. It should be noted that, due to the large size of the second drain outlet 30a, there is virtually no risk of clogging.

[0077] For example, in some embodiments, the size of the first drain outlet 30b is smaller than the size of the second drain outlet 30a.

[0078] In some embodiments, please refer to Figures 2 and 10. The detergent dispensing device 100 includes a nozzle unit 200. The liquid outlet water path is located inside the nozzle unit 200. The water outlet end of the first water path 40A and the water outlet end of the second water path 50A are located inside the nozzle unit 200. The water outlet end of one of the first water path 40A or the second water path 50A is provided with a flow guiding channel 201a, which is used to guide the fluid toward the water outlet end of the other.

[0079] Within the nozzle unit 200, the flow channel 201a brings the outlet ends of the first water path 40A and the second water path 50A close to each other. After the fluid from the first water path 40A is sprayed out, it mixes with the fluid sprayed out from the second water path 50A. In this way, the impact force of the fluid spraying out enhances the mixing effect of the two fluids, thereby promoting the dissolution of detergent and further improving the washing ratio.

[0080] In some embodiments, the cross-sectional area of ​​the flow channel 201a gradually increases along the direction of fluid movement.

[0081] It should be noted that the flow cross-section is largest at the end of the guide channel 201a along the flow direction. Under the guidance of the guide channel 201a, the fluid in it tends to concentrate towards the end closer to the liquid outlet, so that it is impacted and fully mixed by the fluid ejected from the outlet of the other water channel.

[0082] In some embodiments, the flow velocity at the outlet of the first water path 40A is less than the flow velocity at the outlet of the second water path 50A, and the guide channel 201a forms the outlet of the first water path 40A.

[0083] That is, the guide channel 201a directs the slower-flowing fluid to the faster-flowing fluid, thereby utilizing the impact force of the faster-flowing second water channel 50A when it exits, to fully mix it with the fluid in the first water channel 40A and enhance the foaming effect of the detergent.

[0084] As an optional embodiment, in which the flow velocity at the outlet of the first water path 40A is less than the flow velocity at the outlet of the second water path 50A, the cross-sectional area of ​​the guide channel 201a gradually increases along the direction of fluid movement. Thus, the flow velocity of the fluid in the first water path 40A decreases in the guide channel 201a, the velocity difference between the outlets of the first water path 40A and the second water path 50A becomes greater, and the impact effect of the fluid in the second water path 50A on the fluid in the first water path 40A is better, resulting in a better mixing effect.

[0085] In some embodiments, the nozzle unit 200 includes a first connector pipe 204, a second connector pipe 205, and a housing 201. The housing 201 has a spray nozzle 201b. The first connector pipe 204 and the second connector pipe 205 are respectively connected to the housing 201. A first water path 40A flows through the first connector pipe 204, and a second water path 50A flows through the second connector pipe 205. The fluids in the first water path 40A and the second water path 50A converge in the housing 201 and are sprayed out through the spray nozzle 201b.

[0086] It should be noted that the liquid outlet path is located inside the nozzle unit 200, and the fluid discharged from the outlet end of the liquid outlet path enters the clothing processing chamber through the spray nozzle 201b. That is, the liquid outlet path is formed inside the shell 201. After the two fluids inside the shell 201 are mixed, they leave the liquid outlet path and are sprayed out from the spray nozzle 201b.

[0087] The first connector pipe 204 can be used as an installation structure for connecting the nozzle unit 200 to the first water channel 40A, and the second connector pipe 205 can be used as an installation structure for connecting the nozzle unit 200 to the second water channel 50A. The structure of the nozzle unit 200 is conducive to fluid mixing, easy to install, and has a relatively compact structure.

[0088] In some embodiments, referring to Figures 1 and 8, the first connector tube 204 and the second connector tube 205 pass through the door seal ring 60, and the housing portion 201 is located radially inside the door seal ring 60. That is, the door seal ring 60 provides a mounting support for the nozzle unit 200, and the nozzle unit 200 is disposed on the door seal ring 60, which facilitates the spraying of fluid from the nozzle 201b onto the clothing to be treated.

[0089] In some embodiments, referring to Figure 9, the spray nozzle 201b is used to spray water downwards and at an angle towards the rear side of the garment processing chamber. That is, the spray nozzle 201b sprays water downwards and backwards, and the fluid at the spray nozzle 201b has both a downward velocity component and a velocity component along the axial rear side of the garment processing chamber. Specifically, the centerline n of the spray nozzle 201b forms an acute angle φ with the reference plane m. The reference plane m is perpendicular to the axis of the garment processing chamber. The detergent mixture is sprayed onto the garments to be treated, which increases the contact area between the detergent and the garments, thus improving the efficiency of the garment processing equipment.

[0090] The value of the acute angle φ is not limited. For example, the acute angle φ formed by the centerline n of the spray nozzle 201b and the reference surface m is 30° to 70°, i.e., 30° ≤ φ ≤ 70°. Examples include 30°, 45°, 50°, 60°, and 70°. This ensures that the fluid sprayed from the spray nozzle 201b is sprayed onto the clothes in the garment processing chamber as much as possible, quickly wetting the clothes, improving detergent utilization, and enhancing the cleaning effect.

[0091] The various embodiments / implementations provided in this application can be combined with each other without creating contradictions.

[0092] 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.
