[0002] This application is based on and claims priority to Chinese patent applications No. 202411205165.2, No. 202411209833.9, No. 202422117018.1, No. 202422132590.5, and No. 202422132590.5, all of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of clothing processing technology, and more particularly to a clothing processing device. Background Technology

[0004] In related technologies, clothing handling equipment mainly includes a clothing handling drum, a detergent dispenser, and piping, with the piping connecting the detergent dispenser and the clothing handling drum. During washing, external water is introduced into the detergent dispenser to form a detergent solution, which then flows through the piping into the clothing handling drum, thus adding detergent. However, detergents, especially laundry powder, often do not dissolve completely and mix unevenly with the water, resulting in insufficient detergent utilization, poor cleaning performance, and a negative impact on user experience. Furthermore, some related technologies use clean water to dilute the solution at the detergent dispenser's drain outlet before it flows along the piping into the clothing handling chamber; however, the cleaning effect remains unsatisfactory.

[0044] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0047] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature and the second feature are in direct contact, or that the first feature and the second feature are in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0048] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example that is included in at least one embodiment or example of the embodiments of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0049] This application provides a clothing processing device. Please refer to Figures 1 and 2. The clothing processing device includes a clothing processing chamber and a detergent dispensing device 100. The clothing processing chamber is used to accommodate clothing to be processed.

[0050] The type of clothing handling equipment is not limited, such as front-loading washing machines, top-loading washing machines, front-loading washer-dryer combos, and top-loading washer-dryer combos. This instruction manual uses a front-loading washing machine as an example.

[0051] Please refer to Figures 2 and 3. The detergent dispensing device 100 includes a first water channel 40A and a second water channel 50A. The first water channel 40A and the second water channel 50A are used to transport fluid. The inlet end of the first water channel 40A is connected to a water source, and the inlet end of the second water channel 50A is also connected to a water source. It can be understood that the fluid in the first water channel 40A and the fluid in the second water channel 50A are ultimately dispensed into the laundry processing chamber.

[0052] It should be noted that the first water channel 40A refers to the fluid flow path and does not specifically refer to a pipe structure. The second water channel 50A refers to the fluid flow path and does not specifically refer to a pipe structure. Please refer to Figures 1 to 8; the dashed lines with arrows in the figures indicate the direction of fluid flow.

[0053] The fluid in the first water channel 40A is a detergent mixture solution.

[0054] 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.

[0055] The fluid in the second water channel 50A is not limited; it can be tap water or a fluid containing detergent. For example, in some embodiments, the garment processing device also includes a circulation pump, and the inlet of the second water channel 50A is connected to the outlet of the circulation pump.

[0056] The fluid in the first water channel 40A and the fluid in the second water channel 50A converge at a point located within the garment processing chamber. In the garment processing device of this embodiment, the detergent mixture converges with the fluid in the second water channel 50A before being sprayed onto the garments to be treated. During this convergence, the two fluids mix and impact each other, further promoting detergent dissolution and foaming. Because the convergence point is located within the garment processing chamber, the distance from the convergence point to the garments being treated is shortened, reducing the degree of foam breakdown in the foamy detergent and facilitating the application of a larger amount of foamy detergent to the garments, thereby improving the cleaning effect.

[0057] Furthermore, in this embodiment, the distance from the confluence of the first water channel 40A and the second water channel 50A to the spray onto the clothing to be treated is relatively short, and the water outlet pattern after the confluence can be better preserved.

[0058] Referring to Figure 1, the garment processing device includes a housing (not shown), a door (not shown), a bobbin assembly 10, and a door seal ring 60. The door seal ring 60 is located on the front side of the bobbin assembly 10, which is housed within the housing. The housing has an opening communicating with the interior of the bobbin assembly 10, and the door is used to open or close the opening. The door seal ring 60 seals the gap between the bobbin assembly 10 and the opening of the housing. When the door is closed, it is sealed against the door seal ring 60. Thus, the communicating space formed between the interior of the bobbin assembly 10, the door seal ring 60, and the door constitutes a garment processing chamber.

[0059] For example, please refer to Figure 1. The first water channel 40A and the second water channel 50A pass through the door seal ring 60. The water outlet of the first water channel 40A and the water outlet of the second water channel 50A are located on the radial inner side of the door seal ring 60. This facilitates the convergence of the fluid in the first water channel 40A and the fluid in the second water channel 50A in the garment processing chamber, which improves the design flexibility of the convergence position and convergence angle of the two fluids.

[0060] In some embodiments, referring to FIG2, the detergent dispensing device 100 includes a detergent supply assembly 30, which has a detergent dispensing chamber through which fluid from the first water path 40A flows. The detergent dispensing chamber is used to contain detergent; that is, the detergent supply assembly 30 is located on the first water path 40A, and the detergent can dissolve in the fluid of the first water path 40A under the action of the fluid in the first water path 40A to form a detergent mixture solution.

[0061] In other embodiments, the detergent supply component 30 is connected to the first water channel 40A, and the detergent in the detergent supply component 30 is mixed with water and then added to the first water channel 40A to form a detergent mixture solution.

[0062] For example, the garment processing equipment also includes a water inlet valve 90, which has a first outlet 90a. The first water path 40A and the second water path 50A are both connected to the first outlet 90a. The water source supplies water to the first water path 40A and / or the second water path 50A through the water inlet valve 90. When the detergent dispensing device 100 dispenses the detergent mixture into the garment processing chamber, it can also assist in water intake and spray the garments to be processed.

[0063] The implementation method where the aforementioned intersection point is located in the garment processing cavity is not limited to any one of the following two methods.

[0064] In some embodiments, the outlet of the first water channel 40A and the outlet of the second water channel 50A are respectively used to inject fluid into the clothing processing chamber, and the fluid ejected from the outlet of the first water channel 40A can meet the fluid ejected from the outlet of the second water channel 50A in the air within the clothing processing chamber. That is, the meeting point is exposed in the space of the clothing processing chamber.

[0065] This embodiment requires no additional piping structure. It utilizes the kinetic energy of the fluid at the outlet of the first water channel 40A and the kinetic energy of the fluid in the second water channel 50A to cause the two fluids to collide. On the one hand, the detergent mixture is impacted and mixed, promoting the full dissolution of the detergent. On the other hand, the two fluids disperse after colliding in the air, which can expand the spraying area and improve the spraying effect.

[0066] There are no restrictions on how the two fluids meet in the air.

[0067] For example, referring to Figure 14, in some embodiments, the fluid in the first water channel 40A has a first flow path in the clothing processing chamber, and the fluid in the second water channel 50A has a second flow path in the clothing processing chamber. The first flow path and the second flow path intersect. It should be noted that the first flow path refers to the movement path of the fluid after leaving the outlet of the first water channel 40A, and the second flow path refers to the movement path of the fluid after leaving the outlet of the second water channel 50A. The first flow path and the second flow path can be straight lines or parabolas, which are not limited here. Moreover, the shape of the fluid after being ejected can be a water curtain or a water column. It can be understood that the water column-type fluid hits the water curtain-type fluid, which is also an implementation where the first flow path and the second flow path intersect.

[0068] In some embodiments, referring to Figure 15, the extension direction of the outlet end of the first water channel 40A (the direction of the center line in the figure) intersects with the extension direction of the outlet end of the second water channel 50A (the direction of the center line in the figure). When the fluid ejection velocity is high, the two fluid streams converge near the intersection point of the aforementioned extension lines. When the fluid ejection velocity is low, the two fluid streams converge below the intersection point of the aforementioned extension lines. In this way, the fluid of the first water channel 40A and the fluid of the second water channel 50A can easily converge in the air within the garment processing chamber.

[0069] Secondly, in some embodiments, please refer to Figures 2, 4, and 7. The detergent dispensing device 100 further includes a mixing space 20a and a spray nozzle 201b. A first water path 40A connects a water source and the inlet of the mixing space 20a, and a second water path 50A connects a water source and the inlet of the mixing space 20a. It is understood that both the first water path 40A and the second water path 50A deliver fluid to the mixing space 20a.

[0070] The fluid from the first water channel 40A and the fluid from the second water channel 50A converge in the mixing space 20a. The mixed fluid in the mixing space 20a is sprayed into the clothing processing chamber through the spray nozzle 201b. The mixing space 20a is located in the clothing processing chamber.

[0071] It should be noted that the above-mentioned mixing space 20a is a chamber formed in the solid structure. The mixing space 20a allows the detergent mixture solution in the first water channel 40A to be mixed more thoroughly with the fluid in the second water channel 50A. Then the mixed fluid is injected into the clothing processing chamber through the spray nozzle 201b.

[0072] In the clothing treatment device of this application embodiment, the detergent mixture solution is sprayed onto the clothes to be treated before it is mixed with the fluid of the second water channel 50A. When the two fluids are mixed, they are mixed and impacted more thoroughly in the mixing space 20a, which can further promote the dissolution of the detergent and also promote the foaming of the detergent.

[0073] For example, the spray nozzle 201b is used to spray water downwards at an angle toward the rear side of the garment processing chamber.

[0074] In other words, referring to Figure 5, the water sprayer 201b sprays water downwards and backwards. The fluid at the water sprayer 201b has both a downward velocity component and a velocity component along the axial rearward side of the garment processing chamber. That is, the centerline n of the water sprayer 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.

[0075] The value of the acute angle φ is unlimited.

[0076] For example, the acute angle φ formed by the centerline n of the spray nozzle 201b and the reference plane 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 applied as much as possible to the clothes inside the garment processing chamber, quickly wetting the clothes, improving detergent utilization, and enhancing the cleaning effect.

[0077] In some embodiments, as shown in Figures 7 and 8, the spray nozzle 201b is disposed on the wall of the mixing space 20a. That is, the mixed fluid in the mixing space 20a is released into the clothing processing chamber after passing through the wall of the mixing space 20a, without the need for an additional drainage pipe, thereby reducing the impact of the water outlet of the mixing space 20a on the fluid.

[0078] In some embodiments, please refer to Figure 8, the outlet end of the second water channel 50A faces the nozzle 201b. This helps to maintain the water outlet shape of the second water channel 50A, so that the fluid ejected from the nozzle 201b retains as much of its motion trend as it was ejected from the outlet end of the second water channel 50A.

[0079] In some embodiments, as shown in Figures 12 and 13, the wall of the mixing space 20a has a first port (reference y). Fluid from the first water path 40A enters the mixing space 20a from the first port, which constitutes the outlet of the first water path 40A. No additional piping structure is required, resulting in a simple structure.

[0080] In some embodiments, referring to Figure 13, the outlet end (reference x) of the second water passage 50A extends into the mixing space 20a. That is, the fluid of the second water passage 50A is ejected from the pipe structure within the mixing space 20a. In other embodiments, referring to Figure 12, the wall of the mixing space 20a has a second port through which the fluid of the second water passage 50A enters the mixing space 20a, and the second port constitutes the outlet end of the second water passage 50A.

[0081] In some embodiments, for example, referring to FIG9, the garment processing device includes a first tubular structure 1001 and a second tubular structure 1002. The second tubular structure 1002 extends at least partially into the first tubular structure 1001 along a direction intersecting the extending direction of the first tubular structure 1001. The mixing space 20a is configured as an enclosing space formed within the first tubular structure 1001 by the projected cylindrical surface of the second tubular structure 1002 along its extending direction. A water nozzle 201b (reference z) is disposed on the wall of the first tubular structure 1001. In this embodiment, the portion of the first tubular structure 1001 upstream of the mixing space 20a (reference y) defines a portion of the first water passage 40A, and a portion of the second water passage 50A (reference x) is formed by the second tubular structure 1002.

[0082] In some embodiments, referring to Figure 10, the garment processing device includes a first tubular structure 1001, a second tubular structure 1002, and a third tubular structure 1003, which are combined in a "Y" shape. The mixing space 20a is configured as the enclosed space formed by the projected cylindrical surface of the first tubular structure 1001 and the second tubular structure 1002 at their intersection along the direction of fluid movement, and the internal space of the third tubular structure 1003. A spray nozzle 201b is located at one end of the third tubular structure 1003 (referring to point z). The first tubular structure 1001 contains a portion forming a first water passage 40A, and the second tubular structure 1002 contains a portion forming a second water passage 50A.

[0083] In some embodiments, referring to FIG11, the garment processing device includes a first tubular structure 1001 and a second tubular structure 1002, wherein the second tubular structure 1002 extends at least partially into the interior of the first tubular structure 1001 along the extending direction of the first tubular structure 1001. A spray nozzle 201b is disposed at one end of the first tubular structure 1001 (referencing z). A mixing space 20a is defined as the space inside the first tubular structure 1001 from the outlet end of the second tubular structure 1002 (referencing y) to the spray nozzle 201b, wherein the portion of the first tubular structure 1001 located upstream of the mixing space 20a defines a portion of a first water passage 40A, and a portion of a second water passage 50A is formed by the second tubular structure 1002.

[0084] In some embodiments, referring to Figure 5, the end of the second water passage 50A is provided with a narrowing section 22 to increase the flow velocity at the outlet of the second water passage 50A. Exemplarily, in some embodiments, the end of the narrowing 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 narrowing section 22. In other embodiments, the end of the narrowing section 22 is also connected to a constant diameter section and / or an expanding diameter section, which form the outlet of the second water passage 50A.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] In some embodiments, the detergent dispensing device 100 includes a turbulence structure 21 disposed in a second water channel 50A for providing a circumferential velocity component to the fluid in the second water channel 50A.

[0089] In some embodiments, referring to FIG5, the detergent dispensing device 100 further includes a turbulence structure 21, which is disposed in the second water channel 50A and is used to provide a circumferential velocity component to the fluid in the second water channel 50A.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] In some embodiments, the garment handling device includes a spray head unit 200, which includes a housing 201 located radially inside a door seal ring 60. The housing 201 forms a mixing space 20a and a spray nozzle 201b. The door seal ring 60 provides mounting support for the spray head unit 200.

[0096] It is understood that both the first water path 40A and the second water path 50A are connected to the nozzle unit 200 and supply fluid into the nozzle unit 200, so that the fluids from the first water path 40A and the second water path 50A converge in the mixing space 20a and are then delivered into the clothing processing chamber through the spray nozzle 201b. The nozzle unit 200 serves to collect the fluids from the first water path 40A and the second water path 50A.

[0097] For example, the nozzle unit 200 further includes a first connector pipe 204 and a second connector pipe 205, both of which are connected to the housing portion 201. The space within the first connector pipe 204 forms part of a first water passage 40A, and the space within the second connector pipe 205 forms part of a second water passage 50A. The first water passage 40A supplies fluid to the nozzle unit 200 via the first connector pipe 204, and the second water passage 50A supplies fluid to the nozzle unit 200 via the second connector pipe 205.

[0098] The door seal ring 60 has a first mounting port and a second mounting port. A first connector tube 204 passes through the first mounting port, and a second connector tube 205 passes through the second mounting port. In this way, the circumferential position of the nozzle unit 200 relative to the door seal ring 60 is defined.

[0099] In some embodiments, referring to FIG5, the nozzle unit 200 includes a baffle 203 formed on the top side of the housing portion 201, and a first connector tube 204 and a second connector tube 205 formed on the same side of the baffle 203. When the nozzle unit 200 is installed, the baffle 203 can abut against the radially inner side of the door seal ring 60, defining the radial position of the nozzle unit 200 relative to the door seal ring 60.

[0100] In some embodiments, please refer to Figures 7 and 8. The nozzle unit 200 includes a nozzle 202 disposed inside the mixing space 20a. The outlet of the nozzle 202 forms the water outlet of the second water path 50A, and the outlet of the nozzle 202 faces the water spray nozzle 201b.

[0101] The fluid in the second water channel 50A is ejected from the outlet of the nozzle 202, impacting the detergent mixture in the first water channel 40A within the mixing space 20a, and then directly enters the garment processing chamber through the spray nozzle 201b. In other words, the shape of the water outlet of the second water channel 50A is less attenuated within the mixing space 20a, and the fluid in the mixing space 20a is ejected in a shape similar to that when ejected from the outlet of the nozzle 202.

[0102] For example, the nozzle 202 has a narrowed section 22, and the turbulence structure 21 is disposed in the second connector pipe 205 and located upstream of the narrowed section 22. After passing through the turbulence structure 21 and the narrowed section 22, the fluid in the second water path 50A is sprayed out of the nozzle 202 with increased velocity and a circumferential velocity component. Thus, the water outlet morphology of the spray nozzle 201b can present a more visually appealing cone shape, and the sprayed mixed fluid is more dispersed, directly spraying onto the clothes to be treated, improving the cleaning effect.

[0103] The nozzle unit 200 can be a one-piece component, meaning that the housing 201, nozzle 202, baffle 203, first connector tube 204, and second connector tube 205 are integrally molded, for example, through injection molding or other processes. Of course, the nozzle unit 200 can also be a separate component, which is assembled after processing.

[0104] In some embodiments, please refer to Figures 7 and 8. A flow channel 201a is formed inside the shell 201. The flow channel is connected to the mixing space 20a. The end of the flow channel 201a constitutes the outlet of the first water path 40A. Along the flow direction of the fluid, the flow cross section of the flow channel 201a gradually increases.

[0105] Understandably, the flow channel 201a has its largest cross-sectional area at the end closest to the mixing space 20a. When the fluid enters the shell 201, guided by the flow channel 201a, it tends to concentrate towards the end closest to the mixing space 20a, filling it as much as possible and mixing thoroughly with the fluid at the outlet of the second water channel 50A. This also reduces the velocity of the fluid entering the mixing space 20a from the first water channel 40A, making the impact effect of the fluid from the second water channel 50A more pronounced.

[0106] In some embodiments, referring to Figure 7, the water outlet cross-sectional area y of the guide channel 201a is larger than the water outlet cross-sectional area x of the nozzle 202, but smaller than the water outlet cross-sectional area z of the spray nozzle 201b. This effectively suppresses backflow caused by excessive flow difference between the first water path 40A and the second water path 50A, thus preventing fluid in the mixing space 20a from flowing back into the first water path 40A as much as possible.

[0107] In some embodiments, referring to Figures 4, 6, and 7, the first connector tube 204 and the second connector tube 205 are arranged along a first direction R, and the housing portion 201 extends along a first direction R. It should be noted that the first direction R is approximately tangential to the door seal ring 60. This facilitates the circumferential spacing of the first connector tube 204 and the second connector tube 205 along the door seal ring 60. It should be noted that the distance between the first connector tube 204 and the second connector tube 205 must ensure that they do not interfere with each other when connecting the pipes.

[0108] The various embodiments / implementations provided in this application can be combined with each other without creating contradictions.

[0109] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
