Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0040] This application provides a nozzle unit 100 for a garment processing device. Referring to Figures 1 and 6, the nozzle unit 100 includes a housing 10 and a first partition structure 20. The first partition structure 20 is disposed inside the housing 10 and divides the space within the housing 10 into at least a first cavity 10A and a second cavity 10B. The first cavity 10A and the second cavity 10B are not interconnected; that is, fluid in the first cavity 10A will not flow into the second cavity 10B, and fluid in the second cavity 10B will not flow into the first cavity 10A.

[0041] This application also provides a garment processing device, including a garment processing chamber, a first water channel 300A and a second water channel 300B for conveying fluid, 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, and the garment processing device may take the form of, but is not limited to, a washing machine, a washer-dryer combo, etc.

[0042] 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.

[0043] In one embodiment, the garment handling device, exemplarily, 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.

[0044] Referring to Figures 1 and 6, the shell 10 has a first water inlet 10a, a first spray nozzle 10b, a second water inlet 10c, and a second spray nozzle 10d. A first chamber 10A connects the first water inlet 10a and the first spray nozzle 10b, and a second chamber 10B connects the second water inlet 10c and the second spray nozzle 10d. In the garment processing device, the first spray nozzle 10b and the second spray nozzle 10d are used to deliver fluid into the garment processing chamber. A first water passage 300A connects a water source and the first water inlet 10a, and a second water passage 300B connects a water source and the second water inlet 10c.

[0045] That is, the fluid in the first water channel 300A can enter the first chamber 10A through the first inlet 10a, leave the first chamber 10A through the first spray nozzle 10b, and enter the clothing processing chamber; the fluid in the second water channel 300B can enter the second chamber 10B through the second inlet 10c, leave the second chamber 10B through the second spray nozzle 10d, and enter the clothing processing chamber.

[0046] The number of first water inlets 10a is at least two, and can be two, three or more. The fluids in each first water inlet 10a can be mixed in the first chamber 10A, and the first spray nozzle 10b is used to discharge the mixture in the first chamber 10A. In the garment processing equipment, the nozzle unit 100 can also play the role of mixing the fluids of multiple water passages connected to the first chamber 10A.

[0047] The nozzle unit 100 provided in this embodiment has a first chamber 10A and a second chamber 10B that are not interconnected. Therefore, the first water inlet 10a and the second water inlet 10c can be connected to water circuits with different functions within the garment processing equipment. This allows the nozzle unit 100 to deliver fluids with different functions into the garment processing chamber, which helps to improve the integration of the nozzle unit 100. The first chamber 10A is connected to multiple first water inlets 10a, enabling the first chamber 10A to mix the fluids, further enhancing the integration of the nozzle unit 100.

[0048] 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 second water path 300B is clean water, which flows out through the second spray nozzle 10d. The first water path 300A and the second water path 300B (and the third 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.

[0049] 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.

[0050] 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.

[0051] For example, 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 second 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.

[0052] In one embodiment, for example, the nozzle 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. The second spray nozzle 10d sprays clean water onto the door glass, helping to keep the door seal ring 200 and the door glass bowl clean. This allows the user to easily observe the interior through the door glass bowl and reduces detergent residue after washing, inhibiting microbial growth. In this embodiment, the nozzle unit 100 serves to dispense detergent components and provide cleaning spray.

[0053] In some embodiments, referring to FIG6, the nozzle unit 100 further includes a second partition structure 30 disposed within the housing 10. The second partition structure 30 divides the space within the housing 10 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.

[0054] It should be noted that the nozzle unit 100 is installed on the garment processing equipment and has certain shape characteristics depending on the installation space inside the garment processing equipment or for aesthetic considerations. The setting of the closed cavity 10E can separate the unused space inside the nozzle unit 100 to adjust the size of the first cavity 10A and the second cavity 10B, which satisfies the design requirements of the first cavity 10A and the second cavity 10B, while also taking into account the considerations of installation space or aesthetics.

[0055] 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.

[0056] 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.

[0057] In some embodiments, after the nozzle unit 100 is installed in place on the garment processing equipment, the enclosed cavity 10E is located on the bottom side of the second partition structure. Along the height direction of the garment processing equipment, the height of any position within the enclosed cavity 10E is lower than the highest position of the second partition structure 30. The position of the enclosed cavity 10E is lower than the position of the first cavity 10A. Under the influence of gravity, the fluid in the first cavity 10A tends to flow towards the second partition structure 30. Therefore, the enclosed cavity 10E helps to reduce the amount of fluid residue in the first cavity 10A, and the second partition structure 30 also helps to guide the fluid in the first cavity 10A to the first spray nozzle 10b.

[0058] For example, the fluid in the first chamber 10A is a detergent mixture solution. Reducing its residue in the first chamber 10A helps to keep the nozzle unit 100 clean and inhibits the growth of microorganisms caused by some of the detergent ingredients.

[0059] 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.

[0060] The housing 10 includes two end plate portions 11, which are arranged at a distance from each other along a first direction R. The end plate portions 11 form the external structure of the nozzle unit 100.

[0061] 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.

[0062] 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.

[0063] In some embodiments, referring to Figure 6, the garment processing device further includes a third water channel 300C, which connects to a water source and one of the first water inlets 10a, and the fluid in the third water channel 300C is clean water. The first water channel 300A delivers a detergent mixture to the first chamber 10A, where it mixes with the clean water delivered by the third water channel 300C. The convergence of the two fluids with different compositions promotes the dissolution and mixing of the detergent. The first spray nozzle 10b delivers 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.

[0064] In one embodiment, for example, the inlet of the third water channel 300C is connected to an inlet valve. The outlets of the first water channel 300A, the second water channel 300B, and the third water channel 300C are all located inside the housing 10.

[0065] In some embodiments, referring to Figures 1 and 4, the nozzle unit 100 further includes a nozzle 40 disposed within the first cavity 10A. The nozzle 40 is connected to one of the first water inlets 10a, and the outlet of the nozzle 40 sprays water toward the first spray nozzle 10b. Thus, on the one hand, the fluid ejected from the outlet of the nozzle 40 will not be completely sprayed onto the inner wall of the first cavity 10A, but will retain its ejected posture and be discharged through the first spray nozzle 10b, thereby driving the fluid discharged from the first spray nozzle 10b outwards; on the other hand, the nozzle 40 protrudes from the inner wall of the first cavity 10A, and when its outlet ejects fluid, it has a suction effect on the fluid near the outlet, improving the mixing and foaming effect.

[0066] 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.

[0067] For example, the nozzle 40 is connected to the first inlet 10a through which the third water channel 300C flows. The third water channel 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.

[0068] 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.

[0069] In some embodiments, please refer to Figures 5 and 6. The first cavity 10A and the second cavity 10B are arranged along the first direction R. The shell portion 10 includes a top wall 14 and a bottom wall 15, which are arranged along the second direction D.

[0070] The shell portion 10 also includes a first sidewall 12 and a second sidewall 13, which are arranged at intervals along a third direction A. In this embodiment, the top wall 14, the bottom wall 15, the first sidewall 12, the second sidewall 13, and the two end plates 11 are connected together to form a box-shaped shell portion 10.

[0071] In some embodiments, both the first inlet 10a and the second inlet 10c are located on the top wall 14, with the first direction R and the second direction D perpendicular to each other. This facilitates centralized pipe routing on the same side of the shell 10.

[0072] 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 position of the second water nozzle 10d is not limited, and the corresponding water spray direction is also not limited. There can be multiple second water nozzles 10d.

[0073] For example, the number of the second water nozzles 10d mentioned above can be multiple, including the first water nozzle 10d1. The first water nozzle 10d1 is disposed on the bottom wall 15 at the part corresponding to the second cavity 10B. In this way, when the nozzle assembly is installed in place, it is beneficial to spray water onto the glass bowl of the door.

[0074] For example, the number of the second water nozzles 10d mentioned above can be multiple, including second water nozzles 10d2. The second water nozzles 10d2 are disposed on the end plate portion 11 corresponding to the second cavity 10B. In this way, when the nozzle assembly is installed in place, it is beneficial to spray water onto the door seal ring 200, which can clean the door seal ring 200 and reduce the probability of microbial growth.

[0075] 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.

[0076] In some embodiments, the cross-sectional area of ​​the second water nozzle 10d provided on the end plate portion 11 is larger than the cross-sectional area of ​​the second water nozzle 10d provided on the bottom wall 15. That is, the fluid in the second cavity 10B is mainly discharged through the second water nozzle 10d provided on the end plate portion 11, so as to improve the cleaning effect on the door seal ring 200.

[0077] 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 second water nozzle 10d provided on the end plate portion 11.

[0078] The inclination angles of the two end plate portions 11 relative to the second direction D can be the same or different.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] Referring, as exemplarily to Figures 7 and 8, in the garment handling apparatus, a first direction R is along the circumference of the door seal ring 200, a second direction D is along the radial direction of the door seal ring 200, and a third direction A is approximately along the axial direction of the garment handling cavity. A first sidewall 12 faces the rear of the garment handling apparatus. A second sidewall 13 faces the front of the garment handling apparatus.

[0083] The first spray nozzle sprays water towards the lower rear side of the garment processing equipment, and the end plate portion 11 with the second spray nozzle 10d faces the right side of the garment processing equipment and is tilted downward, so that the second spray nozzle 10d sprays water approximately around the circumference of the door seal ring 200.

[0084] In some embodiments, referring to FIG1, the nozzle unit 100 further includes a first connector pipe 51, a second connector pipe 52 and a third connector pipe 53. The number of first water inlets 10a is at least two. The first connector pipe 51 and the second connector pipe 52 are respectively connected to one first water inlet 10a. The third connector pipe 53 is connected to the second water inlet 10c. The first connector pipe 51, the second connector pipe 52 and the third connector pipe 53 are arranged along the first direction R and are all disposed on the top wall 14 of the housing 10.

[0085] It is understandable that the first water passage 300A can flow through the first connector pipe 51, the second water passage 300B can flow through the third connector pipe 53, and the third water passage 300C can flow through the second connector pipe 52. That is, the first connector pipe 51, the second connector pipe 52, and the third connector pipe 53 can transport fluid into the shell 10.

[0086] As an optional embodiment, the first connector tube 51, the second connector tube 52, the third connector tube 53 and the top wall 14 of the shell 10 can be integrally formed parts, with the nozzle 40 separately mounted on the top wall 14 of the shell 10, and the top wall 14 of the shell 10 connected to the rest of the shell 10 by welding.

[0087] In one embodiment, the door seal ring 200 has a plurality of mounting holes spaced apart in the circumferential direction. The first connector tube 51, the second connector tube 52, and the third connector tube 53 pass through the mounting holes to fix the nozzle unit 100 circumferentially on the door seal ring 200.

[0088] In one embodiment, the nozzle unit 100 further includes a turbulence structure 80 disposed in the second connector pipe 52 for providing a circumferential velocity component to the fluid in the second connector pipe 52.

[0089] The aforementioned circumferential velocity component refers to the fluid in the second connector pipe 52 after passing through the turbulent structure 80, whose velocity direction has a non-zero component in the circumferential direction of the second connector pipe 52, and the circumferential direction of the second connector pipe 52 is perpendicular to the extension direction of the second connector pipe 52.

[0090] 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.

[0091] 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.

[0092] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature and the second feature are in direct contact, or that the first feature and the second feature are in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
