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

[0066] This application provides a nozzle unit 100 for a garment processing device. Referring to Figures 1 and 4, the nozzle unit 100 includes a housing 10 and a plurality of connector tubes 50. The housing 10 has interconnected cavities and spray nozzles, which can discharge fluid from the cavities, such as by introducing the fluid from the cavities into the garment processing chamber of the garment processing device.

[0067] This application also provides a garment processing device. Referring to Figures 10 to 14, the garment processing device includes a garment processing chamber (not shown), multiple water inlet pipes 300 and multiple pipe clamps 400, and a nozzle unit 100 as described in any embodiment of this application. The garment processing chamber is used to accommodate garments to be processed. The garment processing device can take the form of, but is not limited to, a washing machine or a washer-dryer combo.

[0068] For example, in one embodiment, the garment processing device further includes a housing, a cylindrical assembly, and a door seal ring 200. The cylindrical assembly and the door seal ring 200 are both disposed in the housing, and the door seal ring 200 is located on the front side of the cylindrical assembly. The communicating space formed by the interior of the cylindrical assembly and the radially inner side of the door seal ring 200 constitutes the garment processing cavity.

[0069] In one embodiment, for example, the garment handling device further includes a door assembly and a door glass bowl, the door glass bowl being disposed on the door assembly. The front of the housing has a garment inlet, through which a user can place garments into the garment handling chamber. The door glass bowl serves to allow the user to observe the interior of the garment handling chamber and to fill a portion of the radially inner side of the door seal ring 200 to reduce garments falling into it. The door assembly is rotatably disposed on the housing to open and close the garment inlet.

[0070] Referring to Figure 2, multiple connector tubes 50 are connected to the housing 10, and the multiple connector tubes 50 are spaced apart along a first direction R. The connector tubes 50 are used to introduce fluid into the cavity. Each connector tube 50 includes a tube body 504 and a first stop portion 501. The first stop portion 501 is disposed on the outer periphery of the end of the tube body 504 away from the housing 10, and the first stop portion 501 protrudes from the outer peripheral surface of the tube body 504, that is, the maximum outer edge dimension of the first stop portion 501 is greater than the outer diameter of the tube body 504.

[0071] The aforementioned multiple connector tubes 50 include, but are not limited to, two, three, or more connector tubes 50.

[0072] The first stop portion 501 may be provided to completely surround the periphery of the tube body 504, or it may not completely surround the periphery of the body 504; this is not limited here.

[0073] The first stop portions 501 of two adjacent connector tubes 50 are staggered in the extension direction of the connector tubes 50, that is, the positions of the first stop portions 501 of two adjacent connector tubes 50 along the extension direction of the connector tubes 50 are not the same.

[0074] It should be noted that the first stop part 501 and the tube body 504 can be an integral component or a separate component, that is, the first stop part 501 is installed on the outer peripheral surface of the tube body 504.

[0075] Please refer to Figures 13 and 14. Multiple inlet pipes 300 are respectively fitted around the outer periphery of the corresponding connector pipe 50. A pipe clamp 400 surrounds the outer periphery of the inlet pipe 300 and locks the inlet pipe 300 onto the pipe body 504. The pipe clamp 400 is located on the side of the first stop portion 501 near the shell portion 10. The aforementioned multiple inlet pipes 300 include, but are not limited to, two, three, or more inlet pipes 300.

[0076] Understandably, within the garment processing equipment, the first stop 501 is located inside the water inlet pipe 300. The pipe clamp 400 locks the water inlet pipe 300 to the pipe body 504. The first stop 501, in conjunction with the pipe clamp 400, limits the movement of the water inlet pipe 300, thus fixing it to the pipe body 504. The first stop 501s of two adjacent connector pipes 50 are staggered, facilitating the staggering of the pipe clamps 400 on adjacent pipe bodies 504, thereby making it easier to install the pipe clamp 400 on the corresponding water inlet pipe 300 portion of the pipe body 504.

[0077] For example, in one embodiment, the maximum outer edge dimension of the first stop portion 501 is larger than the inner diameter of the water inlet pipe 300. The water inlet pipe 300 has a certain elasticity. After the first stop portion 501 is pushed into the water inlet pipe 300, the inner wall of the water inlet pipe 300 undergoes elastic deformation, so that the inner wall of the water inlet pipe 300 is tightly attached to the first stop portion 501, which enhances the reliability of the connection and also helps to improve the sealing performance between the water inlet pipe 300 and the connector pipe 50.

[0078] The form of the pipe clamp 400 is not limited. For example, in one embodiment, the pipe clamp 400 includes a hoop and a latch. The two ends of the hoop are respectively provided with latches. When the latches are engaged, the pipe clamp 400 is wrapped around to lock the water inlet pipe 300 passing through the hoop onto the pipe body 504.

[0079] In some embodiments, please refer to FIG7, the first stop portion 501 is provided to protrude radially from the outer peripheral surface of the tube body 504, and the tube body 504 is basically cylindrical in shape.

[0080] Extending from the middle region of the connector tube 50 towards both ends, the radial dimension of the first stop portion 501 along the tube body 504 gradually decreases. The dimension d2 of the middle region in the figure is obviously larger than the dimension d1 of one of the ends, and also larger than the dimension d3 of the other end.

[0081] In other words, looking along the extension direction of the connector pipe 50, the radial dimension of the first stop part 501 gradually decreases from the middle part to both ends. In other words, the outer wall of the first stop part 501 is composed of at least two conical surfaces. The conical surfaces can play a guiding role, so that when the first stop part 501 is pushed into or out of the water inlet pipe 300 along the extension direction of the connector pipe 50, it is easier to move and less likely to scratch the inner wall of the water inlet pipe 300.

[0082] In some embodiments, referring to Figures 2 and 3, the connector tube 50 includes a second stop portion 502, which is disposed on the outer periphery of the tube body 504. The second stop portion 502 protrudes radially from the outer peripheral surface of the tube body 504, meaning that the maximum outer edge dimension of the second stop portion 502 is greater than the outer diameter of the tube body 504. The second stop portion 502 is located on the side of the first stop portion 501 facing the shell portion 10. The portion of the tube body 504 located between the first stop portion 501 and the second stop portion 502 is the tube clamp 400 mounting area, which is used to mate with the tube clamp 400.

[0083] Understandably, during the process of pushing the first stop 501 into the water inlet pipe 300, the length of the portion of the water inlet pipe 300 sleeved on the connector pipe 50 gradually increases until one end of the water inlet pipe 300 abuts against the side of the second stop 502 near the first stop 501. The second stop 502 plays a positioning role during the installation process, making it convenient for operators to accurately install the water inlet pipe 300 in the preset position, which helps to improve assembly quality and increase assembly speed.

[0084] In some embodiments, the radial dimension of the first stop portion 501 along the pipe body 504 is smaller than the radial dimension of the second stop portion 502 along the pipe body 504. In this way, the first stop portion 501 can be pushed into the water inlet pipe 300 more smoothly, while the second stop portion 502 can play a more effective role in stopping and positioning.

[0085] In some embodiments, referring to Figures 3 and 13, the connector tube 50 includes an insertion positioning portion 503, which is disposed on the outer periphery of the tube body 504. The insertion positioning portion 503 protrudes radially from the outer peripheral surface of the tube body 504, meaning that the maximum outer edge dimension of the insertion positioning portion 503 is greater than the outer diameter of the tube body 504. The insertion positioning portion 503 is located on the side of the second stop portion 502 facing the shell portion 10. The portion of the tube body 504 between the insertion positioning portion 503 and the shell portion 10 is an insertion area, which is used to insert the door seal ring 200 of the garment processing equipment.

[0086] The connector tube 50 not only serves to transport fluid from the inlet pipe 300 to the cavity of the housing 10, but also acts as a limiter when the nozzle unit 100 is installed on the door seal ring 200. For example, in one embodiment, the door seal ring 200 is provided with a plurality of mounting holes arranged circumferentially, and the connector tube 50 passes through each mounting hole until it is inserted into the door seal ring 200, thereby limiting the nozzle unit 100 circumferentially on the door seal ring 200.

[0087] In some embodiments, the radial dimension of the insertion positioning part 503 along the tube body 504 is smaller than the radial dimension of the second stop part 502 along the tube body 504. This allows the insertion positioning part 503 to pass more smoothly through the mounting holes on the door seal ring 200 during insertion.

[0088] As an optional embodiment, the first stop portion 501, the second stop portion 502, and the insertion positioning portion 503 are arranged in descending order of their radial dimensions along the tube body 504 as follows: second stop portion 502, insertion positioning portion 503, and first stop portion 501.

[0089] As an optional embodiment, the first stop portion 501 and the insertion positioning portion 503 may have the same radial dimension along the tube body 504.

[0090] In some embodiments, referring to FIG6, the center lines of the plurality of connector tubes 50 along their extension directions are located in the same plane, and the plurality of connector tubes 50 bend to the same side from the housing portion 10 to the direction away from the housing portion 10.

[0091] In other words, the connector pipes 50 are arranged side by side and extend in the same direction, which facilitates centralized pipe laying and the assembly of the water inlet pipe 300 with the nozzle unit 100. The multiple connector pipes 50 are bent to the same side to avoid other structures of the clothing processing equipment during installation.

[0092] Of course, in other embodiments, the multiple connector pipes 50 may all be straight pipes without bending, or may all be composed of straight pipes connected in multiple directions, with the joints between the straight pipes connected by bends.

[0093] In some embodiments, referring to FIG6, the nozzle unit 100 further includes a first partition structure 20, which is disposed inside the housing 10 and divides the cavity into at least a first cavity 10A and a second cavity 10B. The first cavity 10A and the second cavity 10B are not in communication with each other, that is, the fluid in the first cavity 10A will not flow into the second cavity 10B, and the fluid in the second cavity 10B will not flow into the first cavity 10A.

[0094] The shell portion 10 has a first water inlet 10a and a second water inlet 10c, and the spray nozzles include a first spray nozzle 10b and a second spray nozzle 10d. A first cavity 10A connects the first water inlet 10a and the first spray nozzle 10b, and a second cavity 10B connects the second water inlet 10c and the second spray nozzle 10d. The first water inlet 10a and the second water inlet 10c are respectively connected to corresponding connector pipes 50.

[0095] The garment processing equipment also includes a first water channel 300A and a third water channel 300B. The first water channel 300A is connected to a water source and a first inlet 10a, and flows through one of the connector pipes 50. The third water channel 300B is connected to a water source and a second inlet 10c, and flows through another connector pipe 50.

[0096] In this embodiment, since the first cavity 10A and the second cavity 10B are not connected to each other, the first water inlet 10a and the second water inlet 10c can be connected to water circuits with different functions in the clothing processing equipment, so that the nozzle unit 100 can inject fluids with different functions into the clothing processing cavity, which is beneficial to improving the integration of the nozzle unit 100.

[0097] Exemplarily, the first spray nozzle 10b and the second spray nozzle 10d are used to dispense fluid into the garment processing chamber. The fluid in the first water path 300A is a detergent mixture solution, which flows out through the first spray nozzle 10b, and the fluid in the third water path 300B is clean water, which flows out through the second spray nozzle 10d. The first water path 300A and the third water path 300B (and the second water path 300C mentioned later) refer to the fluid flow paths and are not limited to specific pipe structures. In this embodiment, the nozzle unit 100 serves to dispense detergent components and assist in water intake.

[0098] 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 detergent.

[0099] The water source mentioned in this manual can be the water supply device of the laundry processing equipment, such as the inlet valve, or the outlet of the circulation pump, which can pump water from the drum assembly into the first water channel 300A or the third water channel 300B. Clean water is not limited to tap water, but refers to a fluid with a lower concentration of detergent components compared to the detergent mixture solution.

[0100] In one embodiment, for example, the garment processing equipment further includes a detergent supply component, which includes a detergent dispenser and a dispenser box. The dispenser box is removably disposed within the detergent dispenser and is used to hold detergents required for washing clothes, such as laundry liquid or fabric softener. A first water path 300A flows through the detergent supply component to form a detergent mixture solution.

[0101] In one embodiment, the garment processing device further includes a water inlet valve, which is connected to an external water supply device, such as a tap water pipe, to deliver clean water to the water inlet valve. The water inlet end of the third water passage 300B is connected to the water inlet valve, and clean water is delivered to the second chamber 10B through the second water inlet 10c.

[0102] In one embodiment, for example, the spray head unit 100 is disposed on the door seal ring 200. A first spray nozzle 10b sprays water towards the garment processing chamber, and a second spray nozzle 10d sprays water towards the door glass bowl and / or the door seal ring 200. The first spray nozzle 10b sprays the detergent mixture onto the garments to be treated, facilitating contact between the detergent components and the garment surface, thus improving the cleaning effect. Since the door glass bowl does not rotate with the drum assembly, it easily accumulates foam and other substances during the washing process. The second spray nozzle 10d sprays clean water onto the door glass bowl and / or the door seal ring 200, helping to keep the door seal ring 200 and the door glass bowl clean. This allows the user to observe the interior through the door glass bowl and reduces detergent residue after washing, inhibiting microbial growth. In this embodiment, the spray head unit 100 serves to dispense detergent components and provide cleaning spray.

[0103] In some embodiments, please refer to FIG6, the number of first inlets 10a is at least two, and the plurality of connector pipes 50 include a first connector pipe 51, a second connector pipe 52 and a third connector pipe 53. The first connector pipe 51 and the second connector pipe 52 are respectively connected to the first inlets 10a, and the third connector pipe 53 is connected to the second inlets 10c.

[0104] The garment processing equipment also includes a second water path 300C, which connects to a water source and one of the first inlets 10a, and flows through one of the first connector pipes 51 and 52, the other being located in the flow path of the first water path 300A. The fluid in the second water path 300C is clean water. The first water path 300A delivers a detergent mixture to the first chamber 10A, where it mixes with the clean water delivered by the second water path 300C. The convergence of the two fluids with different compositions promotes the dissolution and mixing of the detergent. The first spray nozzle 10b dispenses the mixture of detergent and clean water into the garment processing chamber, which facilitates full contact between the detergent and the garments to be processed, improving the cleaning effect.

[0105] In some embodiments, among the first connector tube 51, the second connector tube 52, and the third connector tube 53, the first connector tube 51 is the shortest and is located between the second connector tube 52 and the third connector tube 53. That is, the first stop portion 501 of the second connector tube 52 is the closest to the housing portion 10 among the three. Thus, when installing the pipe clamp 400, there is sufficient space between the first connector tube 51 and the second connector tube 52, and between the second connector tube 52 and the third connector tube 53, allowing the pipe clamp 400 to be staggered for easy installation.

[0106] In some embodiments, the shell portion 10 includes a top wall 14 and a bottom wall 15, which are arranged along a second direction D, and the first direction R is perpendicular to the second direction D. The shell portion 10 also includes a first side wall 12 and a second side wall 13, as well as end plate portions 11. The first side wall 12 and the second side wall 13 are arranged at intervals along a third direction A, and the two end plate portions 11 are arranged at intervals along the first direction R. The end plate portions 11 serve as the external structure of the nozzle unit 100. In this embodiment, the top wall 14, the bottom wall 15, the first side wall 12, the second side wall 13, and the two end plate portions 11 are connected together to form a box-shaped shell portion 10.

[0107] In some embodiments, the first connector tube 51, the second connector tube 52 and the third connector tube 53 are all connected to the top wall 14, which facilitates the centralized arrangement of tubes on the same side of the shell 10.

[0108] In some embodiments, referring to FIG6, the space between the first spacer structure 20 and one of the end plate portions 11 forms a second cavity 10B. That is, the second cavity 10B is located at one end of the shell portion 10 along the first direction R. The number of second water nozzles 10d is at least two, and their positions and corresponding water spray directions are not limited.

[0109] For example, the above-mentioned at least two second water nozzles 10d include a first water nozzle 10d1, which is disposed on the bottom wall 15 at the part corresponding to the second cavity 10B. Thus, when the nozzle assembly is installed in place, it is beneficial to spray water onto the door glass bowl.

[0110] For example, the above-mentioned at least two second water nozzles 10d include a second water nozzle 10d2, which is disposed on the end plate portion 11 corresponding to the second cavity 10B. Thus, when the nozzle assembly is installed in place, it is beneficial to spray water onto the door seal ring 200, which cleans the door seal ring 200 and reduces the probability of microbial growth.

[0111] For example, the bottom wall 15 and the end plate 11 corresponding to the second cavity 10B are respectively provided with second water nozzles 10d to expand the spraying range and improve the effect.

[0112] In some embodiments, the cross-sectional area of ​​the second water spray nozzle 10d2 disposed on the end plate portion 11 is larger than the cross-sectional area of ​​the first water spray nozzle 10d1 disposed on the bottom wall 15. That is, the fluid in the second cavity 10B is mainly discharged through the second water spray nozzle 10d2 disposed on the end plate portion 11, so as to improve the cleaning effect on the door seal ring 200.

[0113] In some embodiments, referring to Figures 2 and 3, the two end plate portions 11 extend obliquely toward each other along the direction from the top wall 14 to the bottom wall 15. This reduces the space occupied by the shell portion 10 along the first direction R and also facilitates adjustment of the spray angle of the first water jet nozzle 10d1 provided on the end plate portion 11.

[0114] The inclination angles of the two end plate portions 11 relative to the second direction D can be the same or different.

[0115] In some embodiments, the first nozzle 10b is disposed on the first sidewall 12, and the third direction A intersects the plane containing the first direction R and the second direction D. In this embodiment, the first nozzle 10b is disposed on the first sidewall 12, and the first inlet 10a is disposed on the top wall 14. The axial direction of the first nozzle 10b is not the same as the axial direction of the first inlet 10a. The fluid enters the first cavity 10A through the first inlet 10a, and the flow direction changes, thereby filling the entire first cavity 10A as much as possible. The fluid ejected from the outlet of the nozzle 40 can mix more thoroughly with the fluid in the first cavity 10A.

[0116] In some embodiments, the first sidewall 12 extends obliquely toward the second sidewall 13 along the direction from the top wall 14 to the bottom wall 15. This facilitates spraying water onto the glass bowl of the door once the nozzle unit 100 is in place.

[0117] In some embodiments, referring to Figure 4, the first sidewall 12 and the second sidewall 13 extend obliquely towards each other along the direction from the top wall 14 to the bottom wall 15. That is, along the direction from the top wall 14 to the bottom wall 15, the cross-sections of the first cavity 10A and the second cavity 10B gradually decrease. This allows for a higher water pressure on the side of the first cavity 10A near the bottom wall 15 and a higher water pressure on the side of the second cavity 10B near the bottom wall 15, resulting in a higher fluid velocity discharged from the first nozzle 10b and the second nozzle 10d.

[0118] For example, referring to Figures 10, 11, and 12, in the garment handling apparatus, the first direction R is along the circumference of the door seal ring 200, the second direction D is along the radial direction of the door seal ring 200, and the third direction A is approximately along the axial direction of the garment handling cavity. The first sidewall 12 faces the rear side of the garment handling apparatus. The second sidewall 13 faces the front side of the garment handling apparatus.

[0119] The first water spray nozzle 10b sprays water towards the rear and lower side of the garment processing equipment, and the end plate portion 11 with the first water spray sub-nozzle 10d1 faces the right side of the garment processing equipment and is tilted downward, so that the first water spray sub-nozzle 10d1 sprays water approximately around the circumference of the door seal ring 200.

[0120] In some embodiments, please refer to Figures 1 and 4. The nozzle unit 100 also includes a nozzle 40 disposed in the first cavity 10A. The nozzle 40 is connected to one end of the first connector tube 51 or the second connector tube 52, and the outlet of the nozzle 40 sprays water toward the first water nozzle 10b.

[0121] Thus, on the one hand, the fluid ejected from the nozzle 40 will not be completely sprayed onto the inner wall of the first cavity 10A, but will retain its ejection posture and be discharged through the first nozzle 10b, thereby driving the fluid discharged from the first nozzle 10b to be ejected; on the other hand, the nozzle 40 is set to protrude from the inner wall of the first cavity 10A, and when the fluid is ejected from its outlet, it has a suction effect on the fluid near the outlet, thereby improving the mixing and foaming effect.

[0122] Please refer to Figure 1. By way of example, the cross-sectional dimension of the first nozzle 10b is larger than the cross-sectional dimension of the outlet of the nozzle 40. The cross-sectional dimension referred to in this specification is the cross-section perpendicular to the direction of fluid flow within the fluid flow channel.

[0123] For example, the nozzle 40 is connected to the first inlet 10a through which the second water passage 300C flows. The second water passage 300C flows through the nozzle 40, that is, the fluid ejected from the outlet of the nozzle 40 is clean water, which mixes with the detergent mixture in the first cavity 10A.

[0124] In some embodiments, referring to Figure 6, the nozzle 40 includes a reducing pipe 41 connected to a first inlet 10a. The reducing pipe 41 is used to increase the flow velocity of the fluid discharged from the outlet of the nozzle 40. It is understood that the cross-sectional area of ​​the reducing pipe 41 gradually decreases along the flow direction of the fluid, thereby increasing the flow velocity. When the flow velocity of the fluid discharged from the outlet of the nozzle 40 is higher, the impact on the detergent mixture solution in the first chamber 10A will be more pronounced, further promoting the mixing and foaming effect of the detergent.

[0125] In one embodiment, for example, the nozzle 40 is connected to one end of the second connector tube 52, and the nozzle unit 100 further includes a turbulence structure 80 disposed in the second connector tube 52 for providing a circumferential velocity component to the fluid in the second connector tube 52. Providing a circumferential velocity component means that the velocity component of the fluid in the second connector tube 52 after passing through the turbulence structure 80 is not zero in the circumferential direction of the second connector tube 52, and the circumferential direction of the second connector tube 52 is perpendicular to the extension direction of the second connector tube 52.

[0126] In this embodiment, the turbulent structure 80 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 end of the second connector pipe 52, it facilitates the conical diffusion of the fluid, resulting in a wider radiation range and better visual effect.

[0127] For example, the turbulent structure 80 includes one or more helical blades that divide at least a portion of the length of the second connector pipe 52 into multiple sub-channels. "Multiple" refers to the number of blades, which can be two, three, or more; that is, the number of helical heads is not less than two, but it is not limited to the number of helical turns. After passing through the helical blades, the fluid exhibits a helical motion. The helical blade structure is simple, has a good turbulence effect on the fluid, and low resistance, reducing energy loss as the fluid passes through.

[0128] In some embodiments, the nozzle unit 100 further includes a second spacer structure 30 disposed within the housing 10, which divides the cavity into a closed cavity 10E. The first cavity 10A, the second cavity 10B, and the closed cavity 10E are not in communication with each other. The closed cavity 10E is a closed chamber that is not in communication with the outside.

[0129] It should be noted that the nozzle unit 100 is located inside the garment processing chamber. Depending on the installation space inside the garment processing equipment or for aesthetic considerations, it has a certain shape. The enclosed chamber 10E can separate the unused space inside the nozzle unit 100 to adjust the size of the first chamber 10A and the second chamber 10B, thus satisfying the design requirements of the first chamber 10A and the second chamber 10B while also taking into account the considerations of installation space or aesthetics.

[0130] The form of the second spacer structure 30 is not limited; it can be plate-shaped, cylindrical, etc. The forms of the first spacer structure 20 and the second spacer structure 30 can be the same or different.

[0131] In some embodiments, referring to FIG6, the first cavity 10A and the closed cavity 10E are located on opposite sides of the second spacer structure 30. That is, the first cavity 10A and the closed cavity 10E are arranged adjacent to each other, and the surfaces on opposite sides of the second spacer structure 30 respectively form part of the inner wall of the first cavity 10A and part of the inner wall of the closed cavity 10E.

[0132] The enclosed cavity 10E and the first cavity 10A are arranged circumferentially along the door seal ring 200, and the enclosed cavity 10E is located below the second partition structure 30. It should be noted that the enclosed cavity 10E being located below the second partition structure 30 means that, along the height direction of the garment handling equipment, the height of any position within the enclosed cavity 10E is lower than the highest position of the second partition structure 30.

[0133] It is understood that the fluid in the first cavity 10A tends to move towards the closed cavity 10E, but is blocked by the second spacer structure 30, making it easy for the fluid in the first cavity 10A to concentrate at the second spacer structure 30. The second spacer structure 30 is used to guide the fluid in the first cavity 10A to the first nozzle 10b. The above-mentioned guidance means that the fluid in the first cavity 10A will flow along the surface of the second spacer structure 30 toward the first nozzle 10b.

[0134] Within the nozzle unit 100, the orientation of the first chamber 10A and the closed chamber 10E facilitates the concentration of fluid towards the second partition structure 30. The second partition structure 30 guides the fluid towards the first spray nozzle 10b, and discharges it into the cylinder assembly through the first spray nozzle 10b. This makes it easier for the fluid in the first chamber 10A to be discharged. After the clothing treatment equipment finishes working, there is less fluid residue in the first chamber 10A, which helps the nozzle unit 100 remain dry when not in operation and inhibits the growth of microorganisms within the nozzle unit 100.

[0135] In some embodiments, referring to Figures 2, 3, and 6, the first cavity 10A, the second cavity 10B, and the closed cavity 10E are arranged along a first direction R. Specifically, the shell portion 10 extends along the first direction R.

[0136] Two end plate portions 11 are arranged at intervals along a first direction R. The end plate portions 11 constitute the external structure of the nozzle unit 100.

[0137] The space between the second spacer structure 30 and one of the end plate portions 11 forms a closed cavity 10E. The structure of the shell portion 10 is relatively simple, easy to manufacture and install, and its linear distribution facilitates the arrangement of the first nozzle 10b and the second nozzle 10d, making it difficult for them to interfere with each other when discharging fluid.

[0138] Of course, in other embodiments, the first cavity 10A, the second cavity 10B and the closed cavity 10E may be arranged in a circumferential manner or nested. For example, the first spacer structure 20 is arranged in a cylindrical shape in the first cavity 10A to separate the second cavity 10B.

[0139] As an optional embodiment, the top wall 14 is an integral structure with the first connector pipe 51, the second connector pipe 52, and the third connector pipe 53. The two end plates 11, the first side wall 12, the second side wall 13, the bottom wall 15, the first spacer structure 20, and the second spacer structure 30 are also integral structures. The nozzle 40 is assembled on the top wall 14 as an independent part and is connected to the first water inlet 10a.

[0140] In some embodiments, referring to FIG6, the shell portion 10 has at least one water inlet, the number of cavities is at least one, and the number of spray nozzles is at least one. The term "at least one" in this specification means one, two, three, or more, and the quantity is not limited.

[0141] The device includes at least one cavity, at least one water inlet (including a first water inlet 10a), and at least one spray nozzle (including a first spray nozzle 10b). The first cavity 10A connects the first water inlet 10a and the first spray nozzle 10b. At least one water path connects a water source to the first water inlet 10a to deliver fluid to the first cavity 10A. The first spray nozzle 10b is used to dispense the fluid from the first cavity 10A into the clothing processing cavity.

[0142] A nozzle 40 is disposed in the first cavity 10A. The nozzle 40 has a flow channel, an inlet, and an outlet, with the flow channel connecting the inlet and the outlet. The inlet is connected to the first water inlet 10a. Fluid introduced through the first water inlet 10a enters the nozzle 40, and the outlet of the nozzle 40 sprays water toward the first spray nozzle 10b. The fluid from the first water inlet 10a is guided through the nozzle 40 to the first spray nozzle 10b, making the spray state of the first spray nozzle 10b more similar to the water outlet state of the nozzle 40. On the one hand, the nozzle 40 is connected to the first water inlet 10a, and its water output has greater energy, which can drive the fluid in the first cavity 10A to be sprayed out of the first spray nozzle 10b, thereby improving the spraying effect. On the other hand, the nozzle 40 protrudes from the inner wall of the first cavity 10A, and when its outlet sprays fluid, it has a suction effect on the fluid near the outlet, further driving the fluid in the first cavity 10A to flow toward the first spray nozzle 10b.

[0143] The nozzle 40 and the shell 10 are separate structures. A separate structure means that multiple structural components are manufactured separately and then assembled together. In other words, the nozzle 40 is assembled onto the shell 10, rather than being integrally formed with the shell 10. This allows the nozzle 40 to be installed more easily inside the shell, and the molding process of the nozzle unit 100 is not too complicated. On the other hand, the design of the nozzle 40 and the shell 10 is more flexible, enhancing the interchangeability of the parts of the nozzle 40 and the shell 10.

[0144] It is understood that the shell 10 is composed of multiple parts, which are separate structures, so that the mouth 40 is installed inside the shell 10 before the multiple parts are assembled to form the complete shell 10 during the assembly process.

[0145] The connection method between the nozzle 40 and the shell 10 is not limited, including but not limited to threaded connection or ultrasonic welding. Ultrasonic welding is a welding technology that uses high-frequency vibration waves. The welding head transmits mechanical vibration energy to the connection between the nozzle 40 and the shell 10, and generates heat energy through friction to melt the material. At the same time, a certain pressure is applied to make the two join together.

[0146] In some embodiments, please refer to Figures 8 and 9, which are exploded views of the nozzle unit 100. It should be noted that the exploded views in the accompanying drawings only illustrate the structural division of the components and do not represent their final assembly form. The shell 10 includes a top wall 14 and a main housing with an opening. The top wall 14 and the main housing are separate structures. The top wall 14 closes the opening. A first water nozzle 10b is disposed in the main housing, and a first water inlet 10a is disposed in the top wall 14. The nozzle 40 is connected to the top wall 14. It should be noted that the top wall 14 and the main housing are separate structures; thus, the nozzle 40 is assembled with the top wall 14 as a single unit before being connected to the main housing.

[0147] Of course, in other embodiments, the shell 10 may also be composed of different structures, and is not limited to the split method of top wall 14 and main box body.

[0148] In some embodiments, referring to Figure 4, each inlet is connected to a corresponding connector pipe 50, and at least one connector pipe 50 and the top wall 14 are integrally formed. An integral structure refers to a structure formed by a single molding process of multiple parts, which simplifies installation and improves structural reliability compared to a split structure. The connector pipe 50 is used to deliver fluid from the water circuit into the cavity through the connected inlet. The integral molding of the connector pipe 50 and the top wall 14 also enhances the sealing between the connector pipe 50 and the inlet.

[0149] In some embodiments, referring to Figures 2, 8, and 9, the housing 10 includes a guide portion 60 disposed at the water nozzle. The guide portion 60 has a flow guiding channel 60a, which communicates with the corresponding water nozzle. The guide portion 60 and the main housing are integrally formed.

[0150] The guide portion 60 has a fluid guiding function, allowing the fluid to flow along the extension direction of the guide channel 60a. Exemplarily, the guide portion 60 protrudes from the outer surface of the main casing, ensuring that the extension length of the guide channel 60a meets design requirements. It should be noted that in these embodiments, each spray nozzle may have a guide portion 60, or some spray nozzles may have guide portions 60 while others may not.

[0151] For example, please refer to Figures 8 and 9. The guide portion 60 includes a first guide portion 601 and a second guide portion 602. The first guide portion 601 and the second guide portion 602 are respectively configured to correspond to different water spray nozzles. The shapes of the first guide portion 601 and the second guide portion 602 may be different and are related to the shape and size of their corresponding water spray nozzles.

[0152] The structure of the guide part 60 is relatively simple. Compared with the mouth part 40 located inside the shell part 10, the guide part 60 is located on the main box body in a more open position. It is an integral structure with the main box body and is relatively simple to manufacture.

[0153] In some embodiments, the guide portion 60 and the main housing are two-color injection molded structures. Two-color injection molding is an injection molding technology that improves the structural performance of a product by injecting two different materials into the same mold. For example, the material of one of the guide portion 60 and the main housing is first injected into the mold. After it cools and solidifies, the mold is rotated or moved to inject the material of the other component into the mold, where it combines with the material of the first component to complete the injection molding process.

[0154] In some embodiments, the cross-sectional area of ​​the flow channel 60a gradually increases along the flow direction of the fluid. For example, the flow channel 60a corresponding to the first nozzle 10b has a gradually increasing cross-sectional area, so that it will not easily interfere with the shape of the fluid ejected from the first nozzle 10b. In embodiments where the fluid ejected from the first nozzle 10b is a detergent mixture solution, the fluid ejected from the first nozzle 10b is accompanied by flowing foam, which can be discharged along the guide channel and enter the garment processing chamber, thereby reducing accumulation on the outer wall of the main box.

[0155] In some embodiments, referring to Figures 2, 3, and 5, the main body includes two end plates 11, a bottom wall 15, a first side wall 12, and a second side wall 13. The two end plates 11 are arranged at intervals along a first direction R, and the bottom wall 15 and the top wall 14 are arranged at intervals along a second direction D. The first side wall 12 and the second side wall 13 are arranged at intervals along a third direction A. The first side wall 12 is provided with a first water spray nozzle 10b. The first direction R is perpendicular to the second direction D, and the third direction A intersects the plane containing the first direction R and the second direction D.

[0156] In other words, the two end plates 11, the bottom wall 15, the first side wall 12, and the second side wall 13 constitute a box-shaped main body. Exemplarily, in the garment handling device, the first direction R is along the circumference of the door seal ring 200, the second direction D is along the radial direction of the door seal ring 200, and the third direction A is along the axial direction of the door seal ring 200. The bottom wall 15 is located on the side of the top wall 14 near the center of the door seal ring 200, and the first side wall 12 is located on the side of the main body away from the garment inlet along the axial direction of the door seal ring 200, which facilitates the first water spray nozzle 10b on the first side wall 12 spraying water towards the rear of the garment handling device.

[0157] In some embodiments, please refer to FIG10, the nozzle unit 100 is disposed at the upper left part of the door seal ring 200, and the nozzle unit 100 may also be disposed at the upper right part of the door seal ring 200. Therefore, the nozzle unit 100 is disposed at an angle relative to the horizontal plane, and under the influence of gravity, the fluid in the first chamber 10A tends to flow downward at an angle.

[0158] The aforementioned upper left portion refers to the area located on the left side of the door seal ring 200, and whose height position is not lower than the center of the door seal ring 200. The aforementioned upper right portion refers to the area located on the right side of the door seal ring 200, and whose height position is not lower than the center of the door seal ring 200.

[0159] In one embodiment, for example, the garment processing apparatus includes a drying tunnel assembly. A detergent supply assembly is disposed at the upper left or upper right portion of the garment processing apparatus and above the door seal ring 200, for supplying a detergent mixture solution to the spray head unit 100 via a first water passage 300C. The drying tunnel body is also disposed above the door seal ring 200 and at the top of the garment processing apparatus, for allowing gas to circulate within the drum assembly through an air inlet on the door seal ring 200 to dry the garments. The placement of the spray head unit 100 at the upper left or upper right portion of the door seal ring 200 facilitates the installation of the fabric hose and avoids obstruction of the drying tunnel assembly.

[0160] The various embodiments / implementations provided in this application can be combined with each other without creating contradictions.

[0161] 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.
