[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 "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and 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, and therefore cannot 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 cannot 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 7 The spray head unit 100 includes a shell 10 and a nozzle 40 .

[0041] The present application also provides a laundry processing device, comprising a laundry processing chamber, at least one water channel, and the nozzle unit 100 of any embodiment of the present application. The laundry processing chamber is used to accommodate laundry to be processed, and the laundry processing device includes but is not limited to a washing machine, a washer-dryer, etc.

[0042] For example, in one embodiment, please refer to Figure 9 and Figure 10 The laundry processing device further includes a housing, a drum assembly, and a door seal 200. Both the drum assembly and the door seal 200 are disposed within the housing, with the door seal 200 located in front of the drum assembly. The interconnected space formed by the interior of the drum assembly and the radially inner side of the door seal 200 constitutes a laundry processing chamber. The housing has a laundry loading port, through which users can place laundry into the laundry processing chamber. The nozzle unit 100 is mounted on the door seal 200.

[0043] For example, in one embodiment, the laundry processing device includes a door assembly mounted on the housing for opening and closing the laundry loading port. The door assembly includes a glass door bowl that arches toward the laundry processing chamber, extending radially inward from the door seal 200. The glass door bowl allows the user to observe the interior of the laundry processing chamber and fills a portion of the radially inner portion of the door seal 200 to prevent laundry from falling into it.

[0044] The shell 10 has at least one cavity, at least one water inlet and at least one water outlet. The at least one mentioned in this specification can be one, two, three or more, and the number is not limited.

[0045] The at least one cavity includes a first cavity, the at least one water inlet includes a first water inlet 10a, and the at least one water spray outlet includes a first water spray outlet 10b. The first cavity 10A communicates with the first water inlet 10a and the first water spray outlet 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 water spray outlet 10b is used to discharge the fluid in the first cavity 10A into the laundry treatment cavity.

[0046] It should be noted that the water source mentioned in this specification can be a water supply device of the clothing processing equipment, such as a water inlet valve, or the outlet of a circulation pump, which can pump water in the barrel assembly into the water channel. The water channel mentioned in this specification (including the first water channel 300C, the second water channel 300B, and the third water channel 300A mentioned below) refers to the fluid flow path of the fluid and is not limited to a specific pipeline structure.

[0047] The nozzle 40 is disposed in the first chamber 10A and has a flow channel, an inlet, and an outlet, with the flow channel connecting the inlet and outlet. The inlet is connected to the first water inlet 10a. Fluid introduced from the first water inlet 10a enters the nozzle 40, and the outlet of the nozzle 40 sprays water toward the first water outlet 10b. The fluid from the first water inlet 10a is directed through the nozzle 40 to the first water outlet 10b, making the water spraying state of the first water outlet 10b closer to the water discharge state of the nozzle 40. On the one hand, the nozzle 40 is connected to the first water inlet 10a, and the energy of the water discharged from the nozzle 40 is greater, which can drive the fluid in the first chamber 10A to be sprayed out of the first water outlet 10b, thereby improving the spraying effect. On the other hand, the nozzle 40 is protruding from the inner wall of the first chamber 10A. When the fluid is sprayed from the outlet, it has a suction effect on the fluid near the outlet, further driving the fluid in the first chamber 10A to flow toward the first water outlet 10b.

[0048] The nozzle 40 and the shell 10 are of a split-body structure. A split-body structure refers to a structure in which multiple structural components are manufactured separately and then assembled together. In other words, the nozzle 40 is assembled to the shell 10 rather than being integrally formed with the shell 10. This, on the one hand, can be more conveniently installed in the shell, and the molding process of the nozzle unit 100 is not overly complicated. On the other hand, the design of the nozzle 40 and the shell 10 is more flexible, enhancing the versatility of the components of the nozzle 40 and the shell 10.

[0049] It is understandable that the shell 10 is composed of multiple components, and these components are separate structures from each other, so that during the assembly process, the mouth 40 is installed in the shell 10 before the multiple components are assembled to form the complete shell 10.

[0050] The nozzle 40 and the shell 10 may be connected in any manner, including but not limited to threaded connection or ultrasonic welding. Ultrasonic welding is a welding technique that utilizes high-frequency vibration waves. The welding head transmits mechanical vibration energy to the connection between the nozzle 40 and the shell 10, generating heat through friction to melt the materials. Simultaneously, a certain amount of pressure is applied to bond the two together.

[0051] In some embodiments, the cross-sectional area of ​​the flow in the nozzle 40 gradually decreases to increase the flow rate of the fluid discharged from the outlet of the nozzle 40. When the flow rate of the fluid discharged from the outlet of the nozzle 40 is higher, the fluid sprayed from the first water spray port 10b is better driven, the spray range is wider, and the spray effect of the nozzle unit 100 is further improved.

[0052] In some embodiments, the flow cross-sectional area of ​​the outlet of the nozzle 40 is smaller than the flow cross-sectional area of ​​the inlet of the nozzle 40 , so that the flow velocity of the fluid at the outlet of the nozzle 40 is increased.

[0053] For some examples, see Figure 7 and Figure 8 The figure shows an exploded view of the nozzle unit 100. It should be noted that the exploded views in the drawings of this specification only illustrate the process structure division of the components and do not represent their final assembly form. The shell 10 includes a top wall 14 and a main box body with an opening. The top wall 14 and the main box body are split structures. The top wall 14 closes the opening. The first water spray port 10b is provided in the main box body, the first water inlet 10a is provided in the top wall 14, and the nozzle 40 is connected to the top wall 14. It should be noted that the top wall 14 and the main box body are split structures. As such, the nozzle 40 is assembled with the top wall 14 as a whole and then connected to the main box body.

[0054] Of course, in other embodiments, the shell 10 may also be composed of different structures, and is not limited to the splitting method of the top wall 14 and the main box body.

[0055] For some examples, see Figure 4 The nozzle unit 100 includes at least one connector pipe 50. Each water inlet is connected to a corresponding connector pipe 50. The at least one connector pipe 50 and the top wall 14 are integrally formed. An integral structure refers to a structure in which multiple parts are formed through an integrated molding process. Compared to a split structure, this can simplify installation and improve structural reliability. The connector pipe 50 is used to deliver fluid in the waterway into the cavity through the connected water inlet. The connector pipe 50 is integrally formed with the top wall 14, which can also enhance the sealing between the connector pipe 50 and the water inlet.

[0056] For some examples, see Figure 5 and Figure 6 The nozzle unit 100 further includes a turbulent flow structure 80 , which is disposed in the joint pipe 50 communicating with the first water inlet 10 a and configured to provide a circumferential velocity component to the fluid in the joint pipe 50 .

[0057] The circumferential velocity component provided above refers to the fluid in the joint pipe 50 passing through the turbulent flow structure 80 , whose velocity component in the circumferential direction of the joint pipe 50 is not zero, and the circumferential direction of the joint pipe 50 is perpendicular to the extension direction of the joint pipe 50 .

[0058] 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 joint pipe 50, the fluid is facilitated to diffuse in a conical shape, with a wider radiation range and better visual effect.

[0059] Exemplarily, the turbulence structure 80 includes one or more spiral blades, which divide at least a portion of the length of the connector pipe 50 into multiple sub-flow channels. The term "multiple" refers to a plurality of blades, which can be two, three, or more. This means the number of helical turns must be at least 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, and provide low resistance, minimizing energy loss as the fluid passes through.

[0060] For some examples, see Figure 2 、 Figure 7 and Figure 8 The shell 10 includes a guide portion 60 disposed at the water outlet. The guide portion 60 has a guide channel 60a that is connected to the corresponding water outlet. The guide portion 60 and the main box body are an integrated structure.

[0061] The guide portion 60 guides the fluid, allowing it to flow along the extension direction of the guide channel 60a. For example, the guide portion 60 protrudes from the outer surface of the main housing, ensuring that the extension length of the guide channel 60a meets the design requirements. It should be noted that in these embodiments, each water outlet may be provided with a guide portion 60, or some water outlets may be provided with a guide portion 60 while others may not.

[0062] For example, see Figure 7 and Figure 8 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 correspond to different water outlet settings respectively. The shapes of the first guide portion 601 and the second guide portion 602 can be different, which is related to the shape and size of the corresponding water outlets.

[0063] The guide portion 60 has a relatively simple structure. Compared with the mouth portion 40 in the shell 10 , the guide portion 60 is located at a relatively open position on the main box body. The guide portion 60 is an integrated structure with the main box body and is relatively simple to manufacture.

[0064] In some embodiments, the guide portion 60 and the main box body are dual-injection molded. Dual-injection molding is an injection molding technique that improves the structural performance of a product by injecting two different materials into the same mold. For example, the material for either the guide portion 60 or the main box body is first injected into the mold. After cooling and solidifying, the mold is rotated or moved, and the material for the other is injected into the mold, where it combines with the first material to complete the injection molding process.

[0065] In some embodiments, the flow cross-sectional area of ​​the flow channel 60a gradually increases along the direction of fluid flow. For example, the flow cross-sectional area of ​​the flow channel 60a corresponding to the first water outlet 10b gradually increases, so that it does not easily interfere with the shape of the fluid sprayed from the first water outlet 10b. In embodiments where the fluid sprayed from the first water outlet 10b is a detergent mixed solution, the first water outlet 10b sprays the fluid, accompanied by flowing foam, which can be discharged along the guide channel and into the laundry treatment chamber, thereby reducing accumulation on the outer wall of the main housing.

[0066] For some examples, see Figure 2 、 Figure 3 and Figure 5 The main box body includes two end panels 11, a bottom wall 15, a first side wall 12, and a second side wall 13. The two end panels 11 are spaced apart along a first direction, and the bottom wall 15 and top wall 14 are spaced apart along a second direction. The first side wall 12 and the second side wall 13 are spaced apart along a third direction, and the first side wall 12 is provided with a first water spray port 10b. The first direction is perpendicular to the second direction, and the third direction intersects the plane of the first and second directions.

[0067] In other words, the two end panels 11, the bottom wall 15, the first side wall 12, and the second side wall 13 form a box-shaped main body. For example, in the laundry processing apparatus, the first direction is along the circumference of the door seal 200, the second direction is along the radial direction of the door seal 200, and the third direction is along the axis of the door seal 200. The bottom wall 15 is located on the side of the top wall 14 closer to the center of the door seal 200, and the first side wall 12 is located on the side of the main body away from the laundry loading port along the axis of the door seal 200. This facilitates the first water spray port 10b on the first side wall 12 to spray water toward the rear of the laundry processing apparatus.

[0068] For some examples, see Figure 6 and Figure 8 At least one water inlet includes a mixing inlet 10f, which communicates with the first chamber 10A. The first chamber 10A is used to mix the liquid from the mixing inlet 10f with the liquid from the first water inlet 10a. The fluid ejected from the nozzle 40 also has an impact on the fluid in the first chamber 10A, thereby promoting the mixing effect in the first chamber 10A.

[0069] For example, the fluid entering the first water inlet 10a is clean water, while the fluid entering the mixing water inlet 10f is a detergent solution. The convergence of these two fluids with different compositions promotes dissolution and mixing of the detergent. The first water spray port 10b is used to deliver a mixture of the detergent solution and clean water into the drum assembly, facilitating full contact between the detergent and the laundry, thereby enhancing cleaning effectiveness. The nozzle 40 is disposed within the first chamber 10A. The fluid ejected from its outlet impacts the fluid in the first chamber 10A and draws in nearby fluid, thereby promoting mixing and foaming of the detergent components.

[0070] It should be noted that clean water is not limited to tap water, but refers to a fluid with a lower detergent component concentration than the detergent mixed solution.

[0071] Illustratively, at least one water channel includes a first water channel 300C and a second water channel 300B. The first water channel 300C connects a water source to the first water inlet 10a, and the second water channel 300B connects the water source to the mixing water inlet 10f. The fluid in the first water channel 300C is clean water, and the fluid in the second water channel 300B is a detergent mixed solution. In one embodiment, the laundry processing device 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 detergents required for washing clothes, such as laundry liquid and softener. The second water channel 300B flows through the detergent supply assembly to form a detergent mixed solution, which is then delivered to the first chamber 10A through the mixing water inlet.

[0072] For some examples, see Figure 6 , at least one cavity includes a second cavity 10B, and the first cavity 10A and the second cavity 10B are not connected to each other. Exemplarily, the shell 10 includes a first partition structure 20, which is disposed inside the shell 10 and separates the space inside the shell 10 into at least the first cavity 10A and the second cavity 10B.

[0073] The at least one water inlet includes a second water inlet 10c, and the at least one water spray outlet includes a second water spray outlet 10d. The second chamber 10B is connected to the second water inlet 10c and the second water spray outlet 10d. Since the first chamber 10A and the second chamber 10B are not connected to each other, the first water inlet 10a and the second water inlet 10c can be connected to waterways with different functions within the laundry treatment device. This allows the spray head unit 100 to deliver fluids with different functions to the laundry treatment chamber, which helps to improve the integration of the spray head unit 100.

[0074] Exemplarily, the fluid sprayed from the second water outlet 10d is clean water, which can clean the door seal 200 and / or the door glass bowl. In one embodiment, the at least one water channel further includes a third water channel 300A, which connects the water source and the second water inlet 10c.

[0075] For some examples, see Figure 2 and Figure 6 The at least one joint pipe 50 includes a first joint pipe 52, a second joint pipe 51, and a third joint pipe 53. The first joint pipe 52 is connected to the first water inlet 10a, the second joint pipe 51 is connected to the mixed water inlet, and the third joint pipe 53 is connected to the second water inlet 10c. Multiple joint pipes 50 are arranged on the top wall 14 at intervals along the circumference of the door seal 200, with the centerlines of each joint pipe 50 along their extension direction lying in the same plane. In other words, the first joint pipe 52, the second joint pipe 51, and the third joint pipe 53 are arranged side by side and extend in the same direction, facilitating centralized pipe routing.

[0076] For some examples, see Figure 1 and Figure 8 The number of the second water spraying outlets 10d is multiple, including a first water spraying sub-outlet 10d1 and a second water spraying sub-outlet 10d2.

[0077] Exemplarily, the first water spray outlet 10d1 is provided at a position of the bottom wall 15 corresponding to the second cavity 10B, so that when the spray head assembly is installed in place, it is conducive to spraying water toward the door glass bowl.

[0078] Exemplarily, the second water spray 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 200, clean the door seal 200, and reduce the chance of microbial growth.

[0079] 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.

[0080] 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.

[0081] It should be noted that the nozzle unit 100 is arranged in 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.

[0082] 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.

[0083] As an optional embodiment, the main box body and the first spacing structure 20 and the second spacing structure 30 are an integrated structure, that is, the two end plate portions 11, the bottom wall 15, the first side wall 12, the second side wall 13, the first spacing structure 20, and the second spacing structure 30 are integrally formed.

[0084] 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.

[0085] In some embodiments, when the nozzle unit 100 is installed in place, the position of the closed cavity 10E is lower than that of the first cavity 10A. Under the influence of gravity, the fluid in the first cavity 10A tends to flow toward the second spacing structure 30. Therefore, the closed cavity 10E is conducive to reducing the amount of fluid residue in the first cavity 10A, and the second spacing structure 30 is also conducive to diverting the fluid in the first cavity 10A to the first water outlet 10b.

[0086] For some examples, see Figure 7 The nozzle unit 100 is arranged at the upper left part of the door sealing ring 200, and the nozzle unit 100 can also be arranged at the upper right part of the door sealing ring 200. Therefore, the nozzle unit 100 is arranged inclined relative to the horizontal plane. Under the influence of gravity, the fluid in the first chamber 10A tends to flow downward.

[0087] The above-mentioned upper left portion refers to the area located on the left side of the door sealing ring 200 and whose height is not lower than the center of the door sealing ring 200. The above-mentioned upper right portion refers to the area located on the right side of the door sealing ring 200 and whose height is not lower than the center of the door sealing ring 200.

[0088] For example, in one embodiment, the laundry processing apparatus includes a drying tunnel assembly.
