Description

A detergent dispensing device and clothing treatment equipment

[0001] Cross-reference to related applications

[0002] This application is based on and claims priority to five Chinese patent applications, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of clothing processing technology, and in particular to a detergent dispensing device and clothing processing equipment. Background Technology

[0004] In related technologies, clothing processing equipment includes a clothing processing drum, a detergent dispenser, and 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 user experience. Furthermore, some related technologies use clean water to dilute the solution at the detergent dispenser's drain outlet before it flows through the piping into the clothing processing chamber; however, the cleaning effect remains unsatisfactory. Summary of the Invention

[0009] A first water passage and a second water passage are used for transporting fluids. The first water passage connects a water source, a first drain outlet, and the mixing space. The second water passage connects a water source and the mixing space.

[0010] The outlet is used to discharge the fluid in the mixing space;

[0011] Wherein, the water outlet cross-sectional area of ​​the first water path is greater than the water outlet cross-sectional area of ​​the second water path; and the water outlet cross-sectional area of ​​the first water path is smaller than the water outlet cross-sectional area.

[0012] In some embodiments, the outlet end of the second water path faces the outlet.

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

[0014] In some embodiments, the detergent dispensing device includes a turbulent structure disposed in the second water channel for providing a circumferential velocity component to the fluid in the second water channel.

[0015] In some embodiments, a flow guide channel is formed at the end of the first water path, the flow guide channel being used to guide the fluid of the first water path toward the outlet end of the second water path; along the flow direction of the fluid, the cross-sectional area of ​​the flow guide channel gradually increases.

[0016] In some embodiments, the nozzle unit includes a housing and a nozzle, the mixing space is located inside the housing, the outlet is disposed on the cavity wall of the housing, the nozzle is disposed inside the mixing space, and the nozzle is disposed at the end of the second water path to increase the flow velocity at the outlet end of the second water path and spray the fluid of the second water path toward the outlet.

[0017] In some embodiments, the nozzle unit includes a housing, the mixing space is located inside the housing, the water outlet is disposed on the cavity wall of the housing, and the nozzle unit further includes a first connector pipe and a second connector pipe, the first connector pipe and the second connector pipe are respectively connected to the housing and are spaced apart along a first direction, the first water path flows through the first connector pipe, and the second water path flows through the second connector pipe.

[0018] In some embodiments, the shell includes a first end wall and a second end wall, the water outlet is formed on the first end wall, the first connector pipe and the second connector pipe are both connected to the second end wall, and the shell bends toward the rearward and downward of the clothing processing chamber of the clothing processing device from the second end wall toward the first end wall.

[0019] In some embodiments, the nozzle unit further includes a baffle surrounding the outer periphery of the housing near one end of the first connector tube and the second connector tube, the baffle being used to abut against the garment processing equipment along the extending direction of the first connector tube or the second connector tube.

[0020] In some embodiments, the garment handling device includes a bobbin assembly and a door seal ring disposed on the front side of the bobbin assembly, through which a first connector tube and a second connector tube pass, and the housing portion is located radially inside the door seal ring.

[0027] In some embodiments, the acute angle formed between the centerline of the water outlet and the reference surface is 30° to 70°, wherein the reference surface is perpendicular to the axis of the clothing processing chamber.

[0028] The detergent dispensing device and clothing treatment equipment provided in this application embodiment have a larger water outlet cross-sectional area at the outlet end of the first water path than at the outlet end of the second water path. This allows for a larger contact area between the detergent components per unit volume and the fluid in the mixing space when the detergent mixture enters the mixing space from the first water path, promoting more uniform mixing and more complete dissolution of the detergent components. The water outlet cross-sectional areas of both the first and second water paths are smaller than the outlet cross-sectional area, allowing the outlet to discharge the fluid in the mixing space more promptly, reducing fluid blockage and the likelihood of backflow into the first and / or second water paths, thus improving the reliability of the detergent dispensing device. Therefore, the detergent dispensing device can promote detergent dissolution, improve the washing ratio of the clothing treatment equipment, and has good reliability. Attached Figure Description

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

[0050] This application provides a detergent dispensing device 100, as shown in FIG2, which includes a detergent supply assembly, a nozzle unit 200, and a first water path 40A and a second water path 50A for conveying fluid.

[0051] This application also provides a clothing processing device, as shown in Figure 1. The clothing processing device includes a clothing processing chamber and a detergent dispensing device 100 as described in any embodiment of this application.

[0052] The clothing processing device provided in this application embodiment has no limited functionality. For example, in addition to washing, the clothing processing device may also have a drying function. The drying function can be used to dry clothing.

[0053] The form of garment handling equipment is not limited, such as drum washing machines, top-loading washing machines, drum washer-dryer combos, and top-loading washer-dryer combos. In drum-type garment handling equipment, the garment handling chamber rotates about an axis extending horizontally or obliquely. In top-loading garment handling equipment, the garment handling chamber rotates about an axis extending vertically.

[0054] The axis of inclination refers to the axis of the garment processing chamber being oblique to the horizontal direction.

[0055] In some embodiments, referring to Figures 1 and 14, the garment handling device may include a door seal ring 60. The axis of the drum assembly 10 extends horizontally or obliquely, and the door seal ring 60 may be disposed at the front end of the drum assembly 10. The garment handling device in this embodiment is also referred to as a drum-type garment handling device, such as a drum washing machine.

[0056] The internal space of the tubular assembly 10 can be at least a part of the garment processing chamber, for example, the garment processing chamber is formed by the communication space between the interior of the tubular assembly 10 and the radially inner side of the door seal ring 60.

[0057] In some embodiments, referring to Figure 13, the garment processing device includes a worktable 80, the axis of which extends vertically from the drum assembly 10, and the worktable 80 may be disposed above the drum assembly 10. The worktable 80 constitutes the exterior surface of the garment processing device. The garment processing device in this embodiment is also referred to as a pulsator-type garment processing device, such as a pulsator washing machine.

[0058] Please refer to Figure 13. The workbench 80 has a clothing inlet 80a, which extends through two surfaces of the workbench 80 in the vertical direction and is connected to the clothing processing chamber.

[0059] In some embodiments, the drum assembly 10 includes a rotatable inner drum with a loading / unloading port. The loading / unloading port can face upwards or forwards. The inner drum can be used to hold loads such as clothing. The inner drum can rotate, for example, clothing, water, and detergent rotate with the inner drum, so that the clothing continuously changes its posture inside the inner drum, and the fluids such as water and detergent change their flow direction with the inner drum.

[0060] For pulsator-type garment handling equipment, the loading and unloading ports face upwards. Users can put or take out garments into or out of the inner drum from above through the garment loading port 80a and the loading and unloading port.

[0061] For drum-type garment handling equipment, the loading and unloading port faces forward. Users can put or take out clothes into or out of the inner drum from the front through the space enclosed by the door seal ring 60 and the loading and unloading port.

[0062] In some embodiments, the inner cylinder may be generally hollow and cylindrical.

[0063] In some embodiments, referring to Figure 1, the tub assembly 10 includes an outer tub 11, and an inner tub may be disposed within the outer tub 11. The outer tub 11 can be used to hold water for washing clothes, and the inner tub is used to hold clothes.

[0064] In this embodiment, water is contained in the outer tub 11, and the inner tub can also be referred to as a perforated inner tub. The space inside the inner tub is at least a portion of the garment processing chamber. Fluid can flow through the flow holes in the inner tub between the space between the outer tub 11 and the inner tub, and between the space inside the inner tub.

[0065] In some embodiments, referring to Figure 1, the outer barrel 11 may be generally hollow and cylindrical.

[0066] In some embodiments, the inner cylinder holds water on its own and can also be referred to as a non-perforated inner cylinder. An outer cylinder 11 may or may not be provided on the outside of the inner cylinder.

[0067] It is understood that in some embodiments, the cylinder assembly 10 may only have an inner cylinder and not the aforementioned outer cylinder 11. In this embodiment, the inner cylinder is a non-perforated inner cylinder that can hold water. The inner cylinder can be a single-cylinder structure. In other words, the clothing processing device has only one cylinder, the inner cylinder.

[0068] In some embodiments, the garment handling equipment includes a housing, with the cylindrical assembly 10 disposed within the housing.

[0069] In some embodiments, the housing may be approximately hexahedral in shape, such as a cube or a cuboid.

[0070] In some embodiments, the housing is provided with an opening communicating with the internal space of the cylinder assembly 10. The opening may also be referred to as a clothing loading port 80a. The clothing handling device includes a door for selectively opening or closing the opening of the housing.

[0071] In some embodiments, the axis of the drum assembly 10 extends in a horizontal or inclined direction, and the door seal ring 60 can be used to seal the gap between the opening of the drum assembly 10 and the housing. The communicating space formed by the door, the door seal ring 60, and the inside of the drum assembly 10 constitutes the garment processing chamber. That is, for a drum-type garment processing device, the communicating space formed by the door, the door seal ring 60, and the inside of the drum assembly 10 constitutes the garment processing chamber.

[0072] In some embodiments, the axis of the cylinder assembly 10 extends in the vertical direction, the worktable 80 can be disposed in the housing, and the door can selectively open or close the clothing loading port 80a. That is, for a pulsator-type clothing handling device, the space inside the inner cylinder can be at least a part of the clothing handling chamber, the worktable 80 and the housing together define the placement chamber, and the cylinder assembly 10 is located in the placement chamber.

[0073] The workbench 80 can be located on the upper part of the box. It can be understood that the projection plane is a plane perpendicular to the front-back direction, and the bisector is a straight line extending horizontally and bisecting the projection of the box. The upper part of the box can be the part of the box located above the bisector.

[0074] The workbench 80 can also be used to install components such as control panels, which can be used to control the operation of the garment processing equipment.

[0075] The following explanation uses a front-loading washing machine as an example.

[0076] For example, referring to Figures 1 and 11, in the detergent dispensing device 100, the detergent supply assembly has a first drain outlet for discharging the detergent mixture solution. The nozzle unit 200 has a mixing space 20a, and a water outlet 201b is formed on the side wall of the mixing space 20a, that is, the water outlet 201b is located on the wall of the mixing space 20a and communicates with the mixing space 20a.

[0077] The first water channel 40A connects to the water source, the first drain outlet, and the mixing space 20a, while the second water channel 50A connects to the water source and the mixing space 20a. Fluid from both the first water channel 40A and the second water channel 50A flows into the mixing space 20a, while the outlet 201b, also known as the liquid outlet, is used to discharge the fluid from the mixing space 20a. It can be understood that the detergent mixture discharged from the first drain outlet enters the first water channel 40A, therefore the fluid flowing into the mixing space 20a from the first water channel 40A is the detergent mixture, while the fluid flowing into the mixing space 20a from the second water channel 50A is related to the water source connected to the second water channel 50A.

[0078] It should be noted that the first water path 40A refers to the fluid flow path and does not specifically refer to a pipe structure. The second water path 50A refers to the fluid flow path and does not specifically refer to a pipe structure. That is, the nozzle unit 200 has space for fluid flow. The first water path 40A and the second water path 50A are two fluid flow paths with different directions. Please refer to Figures 1 to 13. The dashed lines with arrows in the figures indicate the direction of fluid flow.

[0079] 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 required that the detergent be completely dissolved. The form of detergent is not limited; it can be powdered laundry detergent, liquid laundry detergent, or fabric softener, etc.

[0080] In one embodiment, for example, the detergent supply component includes a detergent dispensing chamber through which a user can add detergent. The detergent dispensing chamber is located on a first water channel 40A. Fluid from a water source enters the detergent dispensing chamber through the first water channel 40A, where it is initially mixed with the detergent to form a detergent mixture solution, and then flows toward a first drain outlet.

[0081] The fluid in the second water path 50A is not limited; it can be tap water or a fluid containing detergent components. 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 circulation pump. In other embodiments, as shown in FIG2, 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.

[0082] It is understandable that the fluids from the first water channel 40A and the second water channel 50A converge in the mixing space 20a of the nozzle unit 200. The two fluids impact and mix with each other, which can promote the dissolution of detergent components, make the detergent components in the detergent mixture solution more uniform, and improve the washing ratio of the clothing treatment equipment.

[0083] Please refer to Figure 11. The cross-sectional area of ​​the outlet end of the first water channel 40A (reference point y) is larger than the cross-sectional area of ​​the outlet end of the second water channel 50A (reference point x), and the cross-sectional area of ​​the outlet end of the first water channel 40A is smaller than the cross-sectional area of ​​the outlet 201b (reference point z). That is to say, the cross-sectional area F1 of the outlet 201b, the cross-sectional area F2 of the outlet end of the first water channel 40A, and the cross-sectional area F3 of the outlet end of the second water channel 50A decrease in that order, i.e., F1>F2>F3.

[0084] The outlet cross-section of the first water channel 40A mentioned above refers to the cross-section at the boundary where the fluid leaves the first water channel 40A and enters the mixing space 20a. Similarly, the outlet cross-section of the second water channel 50A refers to the cross-section at the boundary where the fluid leaves the second water channel 50A and enters the mixing space 20a. The outlet cross-section of the water outlet 201b refers to the cross-section at the boundary where the fluid leaves the mixing space 20a and enters the external environment (such as the clothing processing chamber).

[0085] The area of ​​the water outlet cross-section of the first water channel 40A is larger than that of the water outlet cross-section of the second water channel 50A. This allows the detergent mixture to have a larger contact area with the fluid in the mixing space 20a per unit volume when it enters the mixing space 20a from the first water channel 40A. This is beneficial for the detergent components to be mixed more evenly and dissolved more completely.

[0086] The water outlet cross-sections of the first water path 40A and the second water path 50A are both smaller than the water outlet cross-sectional area of ​​the outlet 201b. This allows the outlet 201b to discharge the fluid in the mixing space 20a as promptly as possible, thereby reducing fluid blockage in the mixing space 20a and decreasing the probability of backflow of fluid from the mixing space 20a to the first water path 40A and the second water path 50A. This is beneficial for improving the reliability of the detergent dispensing device 100.

[0087] In the embodiments of the clothing processing device of this application, the water outlet 201b is directly connected to the clothing processing chamber, and the fluid from the water outlet 201b directly enters the clothing processing chamber and acts directly on the clothing.

[0088] Therefore, the detergent dispensing device 100 provided in this application embodiment can promote detergent dissolution, improve the washing ratio of the clothing treatment equipment, and has good reliability. In some embodiments, please refer to Figures 8 and 12, the water outlet of the second water channel 50A faces the water outlet 201b. "The water outlet of the second water channel 50A faces the water outlet 201b" means that the orientation of the water outlet of the second water channel 50A is the same as the orientation of the water outlet 201b. For example, the water outlet of the second water channel 50A and the water outlet 201b both face the same side in the first direction. That is, the axis of the water outlet of the second water channel 50A is parallel to or coincides with the axis of the water outlet 201b.

[0089] The axis of outlet 201b refers to the straight line passing through the center point of the flow section of outlet 201b.

[0090] In this way, the fluid discharged from the outlet of the second water channel 50A can drive the fluid in the mixing space 20a to be sprayed out through the outlet 201b, and the water outlet pattern of the outlet 201b is similar to the water outlet pattern of the second water channel 50A, so that no additional drainage pipe needs to be installed at the outlet 201b.

[0091] For example, the water outlet 201b delivers the fluid in the mixing space 20a into the garment processing chamber of the garment processing device. The aforementioned delivery into the garment processing chamber means that the fluid ejected from the water outlet 201b does not require guidance from other structures, but is directly sprayed into the garment processing chamber under inertial influence, thus spraying the garments in the chamber and improving the washing effect.

[0092] In some embodiments, please refer to FIG9, a narrowing section 22 is formed at the end of the second water passage 50A to increase the flow velocity at the outlet of the second water passage 50A.

[0093] 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 forms the outlet of the second water passage 50A, and the fluid of the second water passage 50A is ejected from the end of the constant diameter section or the expanded diameter section.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] In some embodiments, referring to Figures 9 and 12, the garment processing device 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] In some embodiments, referring to Figure 12, a flow guiding channel 201a is formed at the end of the first water channel 40A. The flow guiding channel 201a is used to guide the fluid of the first water channel 40A toward the outlet end of the second water channel 50A. That is, the outlet ends of the first water channel 40A and the second water channel 50A are close to each other. Under the backflow effect of the flow guiding channel 201a, the detergent mixture of the first water channel 40A is discharged toward the outlet end of the second water channel 50A, so that the fluid discharged from the second water channel 50A directly impacts the fluid from the first water channel 40A in the mixing space 20a and promotes mixing and dissolution.

[0104] Please refer to Figure 11. Along the flow direction of the fluid, the cross-sectional area of ​​the flow guide channel 201a gradually increases.

[0105] It should be noted that the end of the guide channel 201a closest to the mixing space 20a has the largest flow cross-section, which is the outlet cross-section of the first water path, with an area of ​​F2. Under the guidance of the guide channel 201a, the fluid in it tends to concentrate towards the end closest to the mixing space 20a, so as to fill the mixing space 20a as much as possible and fully mix with the fluid at the outlet of the other water path.

[0106] In some embodiments, referring to Figures 9 and 11, the nozzle unit 200 includes a housing 201 and a nozzle 202. A mixing space 20a is located inside the housing 201, and a water outlet 201b is disposed on the cavity wall of the housing 201. The nozzle 202 is disposed inside the mixing space 20a and at the end of the second water passage 50A, which is used to increase the flow velocity at the outlet end of the second water passage and spray the fluid of the second water passage toward the water outlet.

[0107] As an alternative embodiment, a reduced diameter section 22 may be formed inside the mouth portion 202.

[0108] It is understood that the nozzle 202 is disposed inside the shell 201 and extends into the mixing space 20a. The fluid of the second water channel 50A enters the mixing space 20a through the nozzle 202. That is, the water outlet section of the second water channel 50A is a certain distance away from the wall of the mixing space 20a, so that the nozzle 202 can draw in the fluid from the first water channel 40A when the fluid is ejected, so as to achieve further mixing of the fluid of the first water channel 40A and the fluid of the second water channel 50A.

[0109] The aforementioned suction of fluid from the first water path 40A refers to the fact that when fluid is ejected from the nozzle 202, under the influence of fluid viscosity and velocity difference, the fluid from the first water path 40A concentrates towards the nozzle 202 to improve the mixing effect of the fluid from the first water path 40A and the fluid from the second water path 50A.

[0110] As an optional embodiment, the nozzle 202 faces the outlet 201b, so that the fluid in the second water path 50A travels a shorter distance from leaving the second water path 50A to being sprayed out of the outlet 201b. This can reduce the dispersion of the water outlet at the outlet end of the second water path 50A and make it easier for air from the external environment to be drawn into the mixing space 20a, thereby improving the foaming effect of the detergent.

[0111] In some embodiments, please refer to FIG8, the nozzle unit 200 further includes a first connector pipe 204 and a second connector pipe 205. The first connector pipe 204 and the second connector pipe 205 are respectively connected to the housing 201 and are spaced apart along the first direction R. The first water path 40A flows through the first connector pipe 204 and the second water path 50A flows through the second connector pipe 205.

[0112] The first connector pipe 204 can serve as an installation structure for connecting the nozzle unit 200 to the first water passage 40A, and the second connector pipe 205 can serve as an installation structure for connecting the nozzle unit 200 to the second water passage 50A. For example, both the first water passage 40A and the second water passage 50A are composed of one or more conduit segments, with one portion of the conduit connected to the first connector pipe 204 and another portion connected to the second connector pipe 205, thereby allowing fluid to be introduced into the nozzle unit 200.

[0113] The first connector tube 204 and the second connector tube 205 are arranged at intervals along the first direction R, that is, the first connector tube 204 and the second connector tube 205 are arranged side by side and there is a certain interval between them. The orientation of the first direction R is not limited (for example, the radial direction perpendicular to the door seal ring 60). In this way, space is reserved for the installation of the nozzle unit 200.

[0114] The nozzle unit 200 can be mounted on the door seal ring 60 of the garment processing equipment. Exemplarily, in some embodiments (see Figures 1 and 14), 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. The nozzle unit 200 is positioned here to facilitate the spraying of fluid from the outlet 201b onto the garments to be processed, achieving a spraying effect.

[0115] In some embodiments, as exemplified in Figure 1, the door seal ring 60 has a first mounting port (not shown) and a second mounting port (not shown). A first connector tube 204 passes through the first mounting port, and a second connector tube 205 passes through the second mounting port. It can be seen that the nozzle unit 200 is connected to the door seal ring 60 via the first connector tube 204 and the second connector tube 205, facilitating installation. During assembly, the nozzle unit 200 can be fixed first, and then the first connector tube 204 and the second connector tube 205 can be connected to the first water passage 40A and the second water passage 50A, respectively.

[0116] It should be noted that the extension direction of the first connector tube 204 and the second connector tube 205 is not limited. The extension directions of the two can be the same or different. As an optional embodiment, the extension directions of the first connector tube 204 and the second connector tube 205 are the same and are both perpendicular to the first direction R.

[0117] In some embodiments, please refer to FIG10, the housing 201 includes a first end wall 2011 and a second end wall 2012, the water outlet 201b is formed on the first end wall 2011, the first connector tube 204 and the second connector tube 205 are both connected to the second end wall 2012, and the housing 201 bends toward the rear lower part of the clothing processing chamber of the clothing processing device from the direction of the second end wall 2012 toward the first end wall 2011.

[0118] In this embodiment, the shell portion 201 not only forms a chamber for fluid movement but also guides the fluid movement in a different direction. The bending feature of the shell portion 201 allows for the transition between different flow directions of the fluid. For example, in an embodiment where both the first connector tube 204 and the second connector tube 205 extend radially along the door seal ring 60, the bending feature of the shell portion 201 causes the fluid flow direction to transition from radial when entering the shell portion 201 to a downward tilt towards the rear of the garment processing chamber when ejected.

[0119] In some embodiments, the nozzle unit 200 further includes a baffle 203 surrounding the outer periphery of the housing portion 201 near one end of the first connector tube 204 and the second connector tube 205. The baffle 203 is used to abut against the garment handling equipment along the extending direction of the first connector tube 204 or the second connector tube 205 to restrict the movement of the nozzle unit 200 along the extending direction of the first connector tube 204 (or the second connector tube 205), thus serving as a stop and positioning function. For example, in an embodiment where the nozzle unit 200 is mounted on the door seal ring 60, the baffle 203 abuts against the radially inner side of the door seal ring 60.

[0120] The nozzle unit 200 in this embodiment can be a one-piece component, meaning that the shell 201, nozzle 202, first connector tube 204, and second connector tube 205 are integrally formed, for example, through injection molding or other processes. Of course, the nozzle unit 200 can also be a separate component, assembled after processing.

[0121] In some embodiments of the garment processing device, referring to Figure 15, no transfer channel 300 is provided between the water outlet 201b and the garment processing chamber. The water outlet 201b in Figure 15 is not connected to the transfer channel 300, that is, the water outlet 201b is directly connected to the garment processing chamber.

[0122] It is understandable that the outlet 201b is a planar structure that runs through the outer surface of the solid part it occupies. That is, the outlet 201b has virtually no length and is roughly a two-dimensional structure. If the outer surface of the solid part containing the outlet 201b is connected to the transfer channel 300 (see Figure 16), then the fluid from the outlet 201b flows through the transfer channel 300 before entering the garment processing chamber. Alternatively, if the outlet 201b is directly connected to the garment processing chamber, it means that the outer surface of the solid part containing the outlet 201b is not connected to the transfer channel 300 (see Figure 15), and the fluid is not constrained by the solid structure at the moment it exits from the outlet 201b.

[0123] In one embodiment, the outlet 201b can also be connected to the transfer channel 300. Referring to Figure 16, the outlet 201b in Figure 16 is connected to the transfer channel 300; that is, the outlet 201b is not directly connected to the garment processing chamber. In other words, the fluid from the outlet 201b flows through the transfer channel 300 before entering the garment processing chamber. The transfer channel 300 can be used to change the flow direction and / or shape of the fluid, allowing fluid to be sprayed onto garments at specific locations and / or sprayed in a specific shape.

[0124] In one embodiment, the water outlet 201b is located inside the garment processing chamber. For example, the water outlet 201b extends radially inward from the door seal ring 60. This brings the water outlet 201b closer to the garments inside the garment processing chamber, reducing the likelihood of defoaming in the fluid ejected from the water outlet 201b.

[0125] In some embodiments of the garment handling device, the water outlet 201b is used to spray water downwards and at an angle toward the rear of the garment handling chamber. That is, referring to Figures 3 and 9, the water outlet 201b sprays water downwards and backwards, and the fluid at the water outlet 201b has both a downward velocity component and a velocity component along the axial rearward direction of the garment handling chamber. Specifically, the centerline n of the water outlet 201b forms an acute angle φ with the reference plane m. The reference plane m is perpendicular to the axis of the garment handling chamber.

[0126] In this way, the detergent mixture is sprayed onto the clothes to be treated, which increases the contact area between the detergent and the clothes, thus improving the efficiency of the clothes processing equipment.

[0127] The value of the acute angle φ is not limited. For example, the acute angle φ formed by the centerline n of the water outlet 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 ejected from the water outlet 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.

[0128] In some embodiments, referring to Figures 3, 7, and 13, the garment handling device includes a dispenser box 140, which forms a detergent dispensing chamber 140a. The detergent dispensing chamber 140a is connected to a first water path 40A. The detergent dispensing chamber 140a is part of the first water path 40A. The detergent dispensing chamber 140a is used to hold detergent. The detergent dispensing chamber 140a can be suitable for holding powdered laundry detergent, or it can be suitable for holding detergents with flow properties, such as liquid laundry detergent. The detergent dispensing chamber 140a is located upstream of the mixing space 20a. The water flow impacts the laundry detergent in the dispensing chamber to initially dissolve the detergent to form a detergent mixture solution, which then enters the mixing space 20a.

[0129] The number of detergent dispensing chambers 140a is unlimited; there can be one or more. Taking multiple detergent dispensing chambers 140a as an example, the multiple detergent dispensing chambers 140a can be arranged sequentially in a direction perpendicular to the vertical direction, such as in a left-right direction or a front-back direction. Each detergent dispensing chamber 140a can dispense detergents with different or the same functions.

[0130] For example, the upper surface of the dispenser box 140 forms an addition port that communicates with the detergent dispensing chamber 140a. The user can add detergent to the detergent dispensing chamber 140a from above through the addition port.

[0131] In some embodiments, referring to Figures 3 to 12, the garment handling device includes a detergent dispenser 30, which includes a mixing chamber 30d. A dispenser box 140 includes at least two detergent dispensing chambers 140a, each with a drain outlet 140b. The at least two drain outlets 140b communicate with the mixing chamber 30d. A first drain outlet 30b is provided on the side wall of the mixing chamber 30d. The detergent dispensing chambers 140a are located upstream of the mixing chamber 30d, which is located upstream of the mixing space 20a.

[0132] Please refer to Figures 3 to 7. The outlet 140b connects to the detergent dispensing chamber 140a and the mixing chamber 30d. The detergent in the detergent dispensing chamber 140a enters the mixing chamber 30d through the outlet 140b. The mixing chamber 30d is used to hold the detergent mixture solution. The first drain outlet 30b is connected to the mixing chamber 30d and is used to drain the detergent mixture solution from the mixing chamber 30d.

[0133] The first water path 40A connects a water source, a detergent dispensing chamber 140a, a mixing chamber 30d, a first drain outlet 30b, and a mixing space 20a. That is, the detergent dispensing chamber 140a, the mixing chamber 30d, and the first drain outlet 30b constitute a part of the first water path 40A. Fluid from the water source flows through the detergent dispensing chamber 140a, the mixing chamber 30d, and the first drain outlet 30b. For example, fluid from the water source in the first water path 40A flows through the detergent dispensing chamber 140a and mixes with detergent to form a detergent mixture solution. The detergent mixture solution flows to the mixing chamber 30d, is discharged through the first drain outlet 30b, and flows into the mixing space 20a.

[0134] The second water channel 50A does not flow through the first drain outlet 30b, and the detergent mixture delivered by the first water channel 40A can merge with the fluid of the second water channel 50A in the mixing space 20a.

[0135] The fluid in the mixing chamber 30d can enter the mixing space 20a and then enter the garment processing chamber. In other words, the detergent mixture in the mixing chamber 30d eventually enters the garment processing chamber to process the clothes.

[0136] In this embodiment, at least two outlets 140b are connected to the mixing chamber 30d, so that the detergent in multiple detergent dispensing chambers 140a can enter the mixing chamber 30d and be discharged to the clothing processing chamber through the mixing chamber 30d, making the water path simple.

[0137] In some embodiments, the detergent in the detergent dispensing chamber 140a can be flushed with water to allow the detergent to enter the mixing chamber 30d. For example, a spray nozzle can spray water into the detergent dispensing chamber 140a, and the water flow impacts and washes the detergent in the dispensing chamber to generate a detergent mixture solution. The detergent mixture solution then enters the mixing chamber 30d through the outlet 140b.

[0138] In some embodiments, the spray nozzle may be formed on the detergent dispenser 30 or the workbench 80, etc.

[0139] In one embodiment, the spray nozzle may be located above the detergent dispensing chamber 140a. For example, the detergent dispenser 30 includes a lid and a body, with the lid positioned above the body and together defining a cavity, a portion of which may be a mixing chamber 30d, and the lid forming the spray nozzle.

[0140] In one embodiment, referring to Figures 3 to 7 and Figure 13, the detergent dispenser 30 includes an overflow chamber 30c for receiving fluid overflowing from the mixing chamber 30d. A second drain outlet 30a is provided on the side wall of the overflow chamber 30c. That is, the second drain outlet 30a communicates with the overflow chamber 30c and can be used to drain the detergent mixture solution from the overflow chamber 30c. Both the mixing chamber 30d and the overflow chamber 30c are part of the cavity of the detergent dispenser 30.

[0141] In this embodiment, when the liquid level in the mixing chamber 30d is not higher than the overflow level, the fluid in the mixing chamber 30d is discharged from the first drain port 30b. When the liquid level in the mixing chamber 30d is higher than the overflow level, the excess fluid in the mixing chamber 30d overflows into the overflow chamber 30c and is discharged from the second drain port 30a. That is, the detergent mixture solution preferentially exits from the first drain port 30b, and the second drain port 30a serves as a safety protection function, enabling the timely discharge of excess fluid from the mixing chamber 30d.

[0142] In one embodiment, referring to Figures 3 to 7, the mixing chamber 30d and the overflow chamber 30c can be distributed along the front-to-back direction, and the dimensions of the mixing chamber 30d and the overflow chamber 30c along the left-to-right direction can be relatively large, so that the mixing chamber 30d can be adapted to multiple detergent dispensing chambers 140a to hold the fluid from the detergent dispensing chambers 140a; the overflow chamber 30c has a moderate volume to receive the fluid overflowing from the mixing chamber 30d.

[0143] In one embodiment, referring to Figures 3 to 7 and Figure 13, the dispenser box 140 is removably disposed within the detergent dispenser 30, for example, within the cavity of the detergent dispenser 30. Exemplarily, the dispenser box 140 is removably disposed within the detergent dispenser 30; for example, at least a portion of the dispenser box 140 can be pulled out to the outside of the detergent dispenser 30, allowing the user to dispense detergent into the detergent dispensing chamber 140a. After dispensing or when washing clothes, the dispenser box 140 can be pushed back into the detergent dispenser 30.

[0144] It is understandable that the shape and size of the outlet 140b are not limited and can be set according to requirements.

[0145] In one embodiment, referring to Figures 3 to 7 and Figure 13, the upper sidewall of the mixing chamber 30d has a filter hole 160a, and the outlet 140b is located above the mixing chamber 30d. The detergent mixture discharged from the outlet 140b enters the mixing chamber 30d after being filtered by the filter plate 160.

[0146] In one embodiment, referring to Figures 3 to 7 and Figure 13, the garment processing device includes a filter plate 160 having filter holes 160a, the filter plate 160 being disposed within a detergent dispenser 30 to define a portion of the space within the detergent dispenser 30 as a mixing chamber 30d.

[0147] In one embodiment, referring to Figures 3 to 7 and Figure 13, the garment handling device includes a water-retaining rib 170, a detergent dispenser 30 having a cavity, the water-retaining rib 170 extending upward from the wall of the cavity, and a filter plate 160 disposed within the cavity. The water-retaining rib 170, the filter plate 160, and a portion of the cavity surface together form a mixing chamber 30d. The filter plate 160 can be the upper sidewall of the mixing chamber 30d, the space above the mixing chamber 30d can be a receiving cavity 30e, and the space in front of the mixing chamber 30d can be an overflow cavity 30c. Exemplarily, the outlet 140b can be located within the receiving cavity 30e. The receiving cavity 30e and the mixing chamber 30d share the filter plate 160 as a sidewall. The filter hole 160a connects the receiving cavity 30e and the mixing chamber 30d, and the outlet 140b communicates with the receiving cavity 30e. The portion of the outlet 140b of the dispenser box 140 located within the receiving cavity 30e.

[0148] In this embodiment, the thickness direction of the filter plate 160 can be aligned with the vertical direction. The fluid discharged from the outlet 140b flows sequentially through the receiving cavity 30e, the filter hole 160a, and the mixing cavity 30d. That is, the fluid discharged from the outlet 140b first enters the receiving cavity 30e, is filtered by the filter plate 160, and then enters the mixing cavity 30d through the filter hole 160a. The filter plate 160 can temporarily retain particles larger than or equal to the pore size of the filter hole 160a on its upper surface, while particles smaller than the pore size of the filter hole 160a can enter the mixing cavity 30d below, and then enter the mixing space 20a through the first outlet 140b. During the washing process, the detergent mixture from the washing dispensing chamber can repeatedly rinse the detergent on the upper surface of the filter plate 160, causing the detergent to dissolve again before entering the mixing cavity 30d. This results in better detergent dissolution and smaller detergent particles entering the garment processing chamber, improving the cleaning effect.

[0149] Understandably, the aperture size and shape of the filter hole 160a can be set as needed. The shape of the filter hole 160a includes, but is not limited to, circles, ovals, polygons, or irregular shapes. Irregular shapes refer to irregular shapes.

[0150] In some embodiments, the filter plate 160 may be generally flat. The filter plate 160 has a simple structure and is easy to manufacture.

[0151] The various embodiments / implementations provided in this application can be combined with each other without creating contradictions.

[0152] 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.
