[0037] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

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

[0040] The embodiment of the present application provides a nozzle unit 100 for a clothes processing device, see Figure 1 and Figure 6 The nozzle unit 100 includes a shell 10 and a first partition structure 20. The first partition structure 20 is disposed inside the shell 10 and separates the space inside the shell 10 into at least a first chamber 10A and a second chamber 10B. The first chamber 10A and the second chamber 10B are not connected to each other. In other words, the fluid in the first chamber 10A will not flow into the second chamber 10B, and the fluid in the second chamber 10B will not flow into the first chamber 10A.

[0041] The present application also provides a clothing treatment device, comprising a clothing treatment chamber, a first water channel 300A and a second water channel 300B for conveying fluid, and a nozzle unit 100 in any embodiment of the present application. The clothing treatment chamber is used to accommodate clothing to be treated, and the clothing treatment device includes but is not limited to a washing machine, a washer-dryer, etc.

[0042] Exemplarily, in one embodiment, the clothing processing device further includes a housing, a barrel assembly and a door seal 200. The barrel assembly and the door seal 200 are both arranged in the housing, and the door seal 200 is located on the front side of the barrel assembly. The connected space formed by the interior of the barrel assembly and the radial inner side of the door seal 200 constitutes a clothing processing chamber.

[0043] For example, in one embodiment, the laundry processing device further includes a door assembly and a door glass bowl, with the door glass bowl being mounted on the door assembly. The front of the cabinet has a clothing inlet through which the user can place laundry into the laundry processing chamber. The door glass bowl serves to allow the user to observe the interior of the laundry processing chamber and to fill a portion of the radially inner side of the door seal 200 to prevent laundry from falling into the chamber. The door assembly is rotatably mounted on the cabinet to open and close the clothing inlet.

[0044] See also Figure 1 and Figure 6 The housing 10 has a first water inlet 10a, a first water spray outlet 10b, a second water inlet 10c, and a second water spray outlet 10d. The first chamber 10A connects the first water inlet 10a and the first water spray outlet 10b, while the second chamber 10B connects the second water inlet 10c and the second water spray outlet 10d. In the laundry processing apparatus, the first and second water spray outlets 10b and 10d are used to deliver fluid into the laundry processing chamber. The first water channel 300A connects a water source to the first water inlet 10a, while the second water channel 300B connects the water source to 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 water inlet 10a, leave the first chamber 10A through the first water spray port 10b, and enter the clothing processing chamber; the fluid in the second water channel 300B can enter the second chamber 10B through the second water inlet 10c, leave the second chamber 10B through the second water spray port 10d, and enter the clothing processing chamber.

[0046] There are at least two first water inlets 10a, and may be two, three, or more. Fluids from each first water inlet 10a can be mixed in the first chamber 10A, and the first water outlet 10b is used to discharge the mixed fluid from the first chamber 10A. The spray head unit 100 in the laundry treatment apparatus can also mix fluids from multiple waterways connected to the first chamber 10A.

[0047] In the spray head unit 100 provided in the embodiment of the present application, since the first chamber 10A and the second chamber 10B are not interconnected, the first water inlet 10a and the second water inlet 10c can be connected to waterways with different functional purposes within the clothing treatment device. This allows the spray head unit 100 to deliver fluids with different functions to the clothing treatment chamber, which helps to improve the integration of the spray head unit 100. The first chamber 10A is connected to multiple first water inlets 10a, allowing the first chamber 10A to mix the fluids, further improving the integration of the spray head unit 100.

[0048] Exemplarily, the first and second water spray ports 10b, 10d are used to deliver fluid to the laundry processing chamber. The fluid in the first water channel 300A is a detergent mixed solution, which flows out through the first water spray port 10b, while the fluid in the second water channel 300B is clean water, which flows out through the second water spray port 10d. The first and second water channels 300A, 300B (and the third water channel 300C mentioned later) refer to the fluid flow paths of the fluids and are not limited to specific pipe structures. In this embodiment, the nozzle unit 100 serves to deliver detergent ingredients and assist in water inflow.

[0049] The detergent mixed solution mentioned in this specification is only for the convenience of description and refers to a mixed solution in which detergent is dissolved. Its mass percentage concentration is not limited, and it does not limit the detergent to be completely dissolved.

[0050] For example, in one embodiment, the laundry processing apparatus further includes a detergent supply assembly, which includes a detergent box and a dispenser box. The dispenser box is retractably disposed within the detergent box and is used to hold detergent required for washing clothes, such as laundry liquid and softener. First water channel 300A flows through the detergent supply assembly to form a mixed detergent solution.

[0051] Exemplarily, in one embodiment, the clothing 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 path 300B is connected to the water inlet valve to deliver clean water to the second chamber 10B through the second water inlet 10c.

[0052] For example, in one embodiment, the nozzle unit 100 is mounted on the door seal 200. The first nozzle 10b sprays water toward the laundry treatment chamber, while the second nozzle 10d sprays water toward the door glass bowl and / or the door seal 200. The first nozzle 10b sprays the detergent mixture onto the laundry, facilitating contact between the detergent components and the laundry surface, improving the cleaning effect. The second nozzle 10d sprays clean water onto the door glass, helping to keep the door seal 200 and the door glass bowl clean. This not only facilitates the user's observation of the interior of the door glass bowl, but also reduces detergent residue after washing, inhibiting the growth of microorganisms. In this embodiment, the nozzle unit 100 serves both the function of dispensing detergent components and spraying for cleaning.

[0053] For some examples, see Figure 6 The nozzle unit 100 further includes a second partition structure 30 disposed within the shell 10. The second partition structure 30 separates the space within the shell 10 into a closed chamber 10E. The first chamber 10A, the second chamber 10B, and the closed chamber 10E are not connected to each other. The closed chamber 10E is a closed chamber that is not connected to the outside.

[0054] It should be noted that the nozzle unit 100 is arranged on the clothing processing device and has certain shape characteristics based on factors such as the installation space in the clothing processing device or aesthetic considerations. The setting of the closed cavity 10E can separate the unused space in the nozzle unit 100 to adjust the size of the first cavity 10A and the second cavity 10B, which not only meets the design requirements of the first cavity 10A and the second cavity 10B, but also takes into account the installation space or aesthetic considerations.

[0055] The second spacing structure 30 may be in any form, such as a plate, a cylinder, etc. The first spacing structure 20 and the second spacing structure 30 may be in the same or different form.

[0056] For some examples, see Figure 6 The first cavity 10A and the closed cavity 10E are located on opposite sides of the second spacing structure 30. In other words, the first cavity 10A and the closed cavity 10E are adjacent to each other, and the surfaces on the opposite sides of the second spacing structure 30 respectively constitute a portion of the inner wall of the first cavity 10A and a portion of the inner wall of the closed cavity 10E.

[0057] In some embodiments, when the spray head unit 100 is installed on the clothing processing device, the enclosed chamber 10E is located at the bottom side of the second partition structure. Along the height of the clothing processing device, the height of any position within the enclosed chamber 10E is lower than the highest position of the second partition structure 30. The enclosed chamber 10E is located lower than the first chamber 10A. Under the influence of gravity, the fluid in the first chamber 10A tends to flow toward the second partition structure 30. Therefore, the enclosed chamber 10E helps reduce the amount of residual fluid in the first chamber 10A, and the second partition structure 30 also helps guide the fluid in the first chamber 10A to the first water spray port 10b.

[0058] Exemplarily, the fluid in the first cavity 10A is a detergent mixed solution, and reducing its residue in the first cavity 10A is beneficial to keeping the nozzle unit 100 clean and inhibiting the growth of microorganisms caused by some formulas in the detergent ingredients.

[0059] For some examples, see Figure 2 、 Figure 3 and Figure 6 The first cavity 10A, the second cavity 10B, and the closed cavity 10E are arranged along the first direction R. Specifically, the shell 10 extends along the first direction R.

[0060] The housing 10 includes two end plates 11 , which are spaced apart along the first direction R. The end plates 11 serve as the external appearance of the showerhead unit 100 .

[0061] The space between the second spacing structure 30 and one of the end plates 11 forms a closed cavity 10E. The shell 10 has a relatively simple structure, making it easy to manufacture and install. The linear arrangement of the first and second water outlets 10b, 10d facilitates the arrangement of the first and second water outlets, preventing them from interfering 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 circumferentially distributed or nested, for example, the first spacing structure 20 is cylindrically arranged in the first cavity 10A to separate the second cavity 10B.

[0063] For some examples, see Figure 6 The laundry processing apparatus further includes a third water channel 300C, which connects a water source to one of the first water inlets 10a and contains clean water. The first water channel 300A delivers a mixed detergent solution to the first chamber 10A, where it mixes with the clean water delivered by the third water channel 300C. The confluence of the two fluids with different compositions promotes the dissolution and mixing of the detergent. The first water outlet 10b delivers the mixed detergent solution and clean water into the laundry processing chamber, facilitating sufficient contact between the detergent and the laundry, thereby enhancing the cleaning effect.

[0064] For example, in one embodiment, the water inlet end of the third water channel 300C is connected to the water inlet valve. The water outlet ends of the first water channel 300A, the second water channel 300B, and the third water channel 300C are all located inside the shell 10.

[0065] For some examples, see Figure 1 and Figure 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 water outlet 10b. This ensures that, on the one hand, the fluid ejected from the nozzle 40 does not completely impinge on the inner wall of the first cavity 10A, but instead remains ejected through the first water outlet 10b, thereby driving the fluid ejected from the first water outlet 10b outward. On the other hand, the nozzle 40 protrudes from the inner wall of the first cavity 10A, and when the fluid is ejected from the nozzle 40, it draws fluid near the outlet, enhancing mixing and foaming effects.

[0066] See also Figure 1 For example, the flow cross section of the first water jet port 10b is larger than the flow cross section of the outlet of the nozzle 40. The flow cross section mentioned in this specification refers to the cross section perpendicular to the flow direction of the fluid in the fluid flow channel.

[0067] Exemplarily, the nozzle 40 is connected to the first water inlet 10a through which the third water channel 300C flows. The third water channel 300C flows through the nozzle 40, that is, the fluid sprayed out from the outlet of the nozzle 40 is clean water, which mixes with the detergent mixed solution in the first cavity 10A.

[0068] For some examples, see Figure 6 The nozzle 40 includes a reducing tube 41 connected to the first water inlet 10a. This reducing tube 41 is used to increase the flow rate of the fluid discharged from the nozzle 40 outlet. It will be appreciated that the flow cross-section of the reducing tube 41 gradually decreases along the flow direction of the fluid, thereby increasing the flow rate. A higher flow rate of the fluid discharged from the nozzle 40 outlet more significantly impacts the detergent mixture in the first chamber 10A, further promoting detergent mixing and foaming.

[0069] For some examples, see Figure 5 and Figure 6 The first cavity 10A and the second cavity 10B are arranged along the first direction R, and the shell 10 includes a top wall 14 and a bottom wall 15, which are arranged along the second direction D.

[0070] The shell 10 further includes a first side wall 12 and a second side wall 13 , which are spaced apart from each other along the third direction A. 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 panels 11 are connected together to form the box-shaped shell 10 .

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

[0072] For some examples, see Figure 6 The space between the first spacing structure 20 and one of the end plates 11 forms a second cavity 10B. That is, the second cavity 10B is located at one end of the shell 10 along the first direction R. The location of the second water spray port 10d is not limited, nor is the corresponding water spray direction. There may be multiple second water spray ports 10d.

[0073] Exemplarily, the number of the above-mentioned second water spray outlets 10d can be multiple including a first water spray outlet 10d1, and the first water spray outlet 10d1 is arranged at the position of the bottom wall 15 corresponding to the second cavity 10B. In this way, when the nozzle assembly is installed in place, it is conducive to spraying water to the door glass bowl.

[0074] Exemplarily, the number of the above-mentioned second water spray outlets 10d can be multiple, including a second water spray sub-outlet 10d2, and the second water spray sub-outlet 10d2 is arranged at the position of the end plate 11 corresponding to the second cavity 10B. In this way, when the nozzle assembly is installed in place, it is beneficial to spray water to the door seal ring 200, clean the door seal ring 200, and reduce the chance of microbial growth.

[0075] Exemplarily, a portion of the bottom wall 15 corresponding to the second cavity 10B and a portion of the end plate 11 corresponding to the second cavity 10B are respectively provided with a second water spraying port 10d to expand the spraying range and improve the effect.

[0076] In some embodiments, the flow cross-sectional area of ​​the second water spray port 10d provided on the end plate 11 is greater than the flow cross-sectional area of ​​the second water spray port 10d provided on the bottom wall 15. In other words, the fluid in the second chamber 10B is primarily discharged through the second water spray port 10d provided on the end plate 11, thereby improving the cleaning effect on the door seal 200.

[0077] For some examples, see Figure 2 and Figure 3 The two end plates 11 extend obliquely toward each other along the direction from the top wall 14 to the bottom wall 15. This not only reduces the space occupied by the shell 10 along the first direction R, but also facilitates adjustment of the spray angle of the second spray port 10d provided on the end plate 11.

[0078] With respect to the second direction D, the inclination angles of the two end plate portions 11 may be the same or different.

[0079] In some embodiments, the first water outlet 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 water outlet 10b is disposed on the first sidewall 12, and the first water inlet 10a is disposed on the top wall 14. The axial direction of the first water outlet 10b is different from that of the first water inlet 10a. Fluid enters the first cavity 10A through the first water inlet 10a, changing its flow direction and thereby filling the entire first cavity 10A as much as possible. Fluid ejected from the outlet of the nozzle 40 can be more thoroughly mixed with the fluid in the first cavity 10A.

[0080] In some embodiments, the first side wall 12 extends obliquely toward the second side wall 13 along the direction from the top wall 14 to the bottom wall 15. In this way, when the spray head unit 100 is installed in place, it is beneficial to spray water toward the door glass bowl.

[0081] For some examples, see Figure 4From the top wall 14 to the bottom wall 15, the first side wall 12 and the second side wall 13 extend obliquely toward each other. In other words, the cross-sections of the first chamber 10A and the second chamber 10B gradually decrease in size from the top wall 14 to the bottom wall 15. This allows for a higher water pressure on the side of the first chamber 10A near the bottom wall 15, while a higher water pressure on the side of the second chamber 10B near the bottom wall 15 is achieved, resulting in a higher flow rate for the fluid discharged from the first and second water outlets 10b, 10d.

[0082] For example, see Figure 7 and Figure 8 In the laundry processing apparatus, the first direction R is along the circumference of the door seal 200, the second direction D is along the radial direction of the door seal 200, and the third direction A is approximately along the axial direction of the laundry processing chamber. The first sidewall 12 faces the rear side of the laundry processing apparatus. The second sidewall 13 faces the front side of the laundry processing apparatus.

[0083] The first water spray port sprays water toward the rear lower side of the clothing processing device, and the end plate portion 11 provided with the second water spray port 10d faces the right side of the clothing processing device and is inclined downward so that the second water spray port 10d sprays water roughly along the circumference of the door sealing ring 200.

[0084] For some examples, see Figure 1 The nozzle unit 100 also includes a first joint pipe 51, a second joint pipe 52 and a third joint pipe 53. The number of the first water inlet 10a is at least two. The first joint pipe 51 and the second joint pipe 52 are respectively connected to one first water inlet 10a, and the third joint pipe 53 is connected to the second water inlet 10c. The first joint pipe 51, the second joint pipe 52 and the third joint pipe 53 are arranged along the first direction R and are all provided on the top wall 14 of the shell 10.

[0085] It is understood that the first waterway 300A can flow through the first joint pipe 51, the second waterway 300B can flow through the third joint pipe 53, and the third waterway 300C can flow through the second joint pipe 52. In other words, the first joint pipe 51, the second joint pipe 52, and the third joint pipe 53 can transport fluid into the shell 10.

[0086] As an optional embodiment, the first joint tube 51, the second joint tube 52, the third joint tube 53 and the top wall 14 of the shell 10 can be an integrally formed part, the mouth 40 is separately installed on the top wall 14 of the shell 10, and the top wall 14 of the shell 10 is connected to the rest of the shell 10 by welding.

[0087] For example, in one embodiment, the door seal ring 200 has a plurality of mounting holes spaced circumferentially, and the first joint pipe 51 , the second joint pipe 52 , and the third joint pipe 53 are respectively provided with mounting holes to fix the nozzle unit 100 on the door seal ring 200 circumferentially.

[0088] For example, in one embodiment, the spray head unit 100 further includes a turbulent flow structure 80 . The turbulent flow structure 80 is disposed in the second joint pipe 52 and is configured to provide a circumferential velocity component to the fluid in the second joint pipe 52 .

[0089] The circumferential velocity component provided above refers to the fluid in the second joint pipe 52 passing through the turbulent structure 80 , whose velocity component in the circumferential direction of the second joint pipe 52 is not zero, and the circumferential direction of the second joint pipe 52 is perpendicular to the extension direction of the second joint pipe 52 .

[0090] In this embodiment, the turbulent structure 80 allows part of the fluid to have both a circumferential movement speed and a forward flow speed, so that part of the fluid roughly moves in a spiral. When the fluid is ejected from the water outlet end of the second joint pipe 52, the fluid is facilitated to diffuse in a conical shape, with a wider radiation range and better visual effect.

[0091] Exemplarily, the turbulence structure 80 includes one or more spiral blades, which divide at least a portion of the length of the second connector pipe 52 into multiple sub-flow channels. The term "multiple" refers to a plurality of blades, which can be two, three, or more. This means that the number of helical turns is not less than two, and does not limit the number of turns. After the fluid passes through the spiral blades, it exhibits a spiral motion. The spiral blades have a simple structure, provide a good flow disturbance effect on the fluid, and provide low resistance, thereby reducing energy loss during passage.

[0092] In the embodiments of the present application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0093] In the description of this specification, reference to the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example.

[0094] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0095] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
