[0038] 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.

[0039] In the description of the embodiments of the present application, it should be noted that the terms "longitudinal", "transverse", "upper", "lower", "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.

[0040] 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.

[0041] The present application embodiment provides a clothes processing device. Figure 8 and Figure 9 The clothing processing device includes a housing, a drum assembly, a door seal 200, a nozzle unit 100, and at least one water channel. The clothing processing device includes but is not limited to a washing machine, a washer-dryer, and the like.

[0042] The cabinet has a clothing loading port, a drum assembly housed within it, and a door seal 200 located in front of the drum assembly. The interconnected space between the drum assembly's interior and the radially inner side of the door seal 200 forms a clothing processing chamber, allowing users to place clothing into the chamber through the loading port.

[0043] For example, in one embodiment, the laundry processing device includes a door assembly, which is mounted on the housing and configured to open and close the laundry loading port. For example, the door assembly includes a glass door bowl that arches toward the laundry processing chamber, extending radially inward of the door seal. The glass door bowl serves to allow the user to observe the interior of the laundry processing chamber and to fill a portion of the radially inner portion of the door seal 200 to prevent laundry from falling into it.

[0044] See also Figure 7 and Figure 1 The spray head unit 100 is mounted on the door seal 200. The spray head unit 100 comprises a housing 10, which has at least one cavity, at least one water inlet, and at least one water outlet. Specifically, the number of cavities can be one, two, three, or more; the number of water inlets can be one, two, three, or more; and the number of water outlets can be one, two, three, or more. The cavities communicate with the corresponding water inlets and outlets; that is, each water inlet communicates with the outlet in the cavity through the cavity in which it is located.

[0045] For example, at least one water channel connects a water source and at least one water inlet. It should be noted that the water channel (and the first water channel 300A, second water channel 300B, and third water channel 300C mentioned below) refers to the fluid flow path of the fluid and is not limited to a specific pipe structure. The fluid in the water channel enters the corresponding cavity through the water inlet to which it is connected, and the water outlet is used to discharge the fluid in the corresponding cavity and ultimately enter the clothing processing chamber.

[0046] The housing 10 includes a first sidewall 13, which faces the laundry inlet, that is, the front of the laundry treatment device. It should be understood that the surface of the first sidewall 13 facing the laundry inlet is the exterior surface of the spray head unit 100 and is easily visible to the user. The surface of the first sidewall 13 facing the laundry inlet is a continuous surface, with the water inlet and spray outlet located on the rest of the housing 10, excluding the first sidewall 13.

[0047] The aforementioned continuous surface refers to the surface of the first side wall 13 facing the clothing inlet being a complete planar structure, without grooves, openings, or other structures formed by removing material, nor any structures protruding from the surrounding surface. The surface of the first side wall 13 facing the clothing inlet can be curved or flat. Thus, in the clothing treatment device provided in the embodiment of the present application, the water inlet and water outlet of the nozzle unit 100 are not easily visible to the user, while the surface of the first side wall 13, being a continuous surface, is more easily visible to the user, resulting in a more aesthetically pleasing appearance of the nozzle unit 100 and an enhanced user experience.

[0048] For example, in one embodiment, the at least one water channel includes a first water channel 300A, wherein the fluid is a detergent mixed solution, which is delivered into the laundry treatment chamber via the nozzle unit 100 and contacts the laundry to be treated. The detergent mixed solution mentioned herein is merely for convenience of description and refers to a mixed solution containing dissolved detergent. The concentration by mass percentage is not limited, and the detergent is not necessarily completely dissolved.

[0049] In some embodiments, the housing 10 is located radially inward of the door seal 200. When the clothing inlet is open, the housing 10 is visible from the outside of the clothing treatment device through the clothing inlet. The user can directly observe the surface of the first sidewall, while structures such as the water inlet and water spray outlet are difficult to see, thereby improving the aesthetics of the clothing treatment device.

[0050] In some embodiments, when the clothing loading port is closed, the shell 10 is exposed to the external field of view of the clothing processing device through the door glass bowl. In this way, regardless of whether the user opens the door assembly or not, the water inlet, water spray outlet and other structures are well hidden, and the overall aesthetics of the clothing processing device is almost unaffected.

[0051] For some examples, see Figure 3 and Figure 7 In orthographic projection along a plane perpendicular to the axis of the drum assembly, the projection of the first side wall 13 defines the projection of the housing 10. In other words, along the front-to-back direction of the laundry processing device, the first side wall 13 can obscure the rest of the housing 10, making it difficult for the user to see the water inlet and water outlet located in the rest of the housing 10.

[0052] For example, in one embodiment, please refer to Figure 2 The shell 10 further includes a second side wall 12, which is arranged along the front-to-back direction of the laundry processing device with the first side wall 13. The second side wall 12 is located on a side of the first side wall 13 away from the laundry loading port.

[0053] For example, in one embodiment, please refer to Figure 4The shell 10 further includes two end plates 11 , which are arranged at opposite ends of the shell 10 along the circumference of the door sealing ring 200 .

[0054] For example, in one embodiment, please refer to Figure 4 and Figure 5 The shell 10 further includes a top wall 14 and a bottom wall 15, which are spaced apart along the radial direction of the door sealing ring 200. The bottom wall 15 is located on one side of the top wall 14 close to the center of the door sealing ring 200.

[0055] As an optional embodiment, the shell 10 of the spray head unit 100 is in a box shape surrounded by a first side wall 13 , a second side wall 12 , a top wall 14 , a bottom wall 15 and two end plates 11 .

[0056] In some embodiments, the end plate 11 is flat, and the plane where the end plate 11 is located is parallel to the axis of the drum assembly. That is, along the front-to-back direction of the laundry processing device, the surface structure of the end plate is difficult to be seen by the user.

[0057] For some examples, see Figure 1 and Figure 8 The at least one water spray port includes a first water spray port 10b, which is disposed on the second sidewall 12 and is configured to spray water into the drum assembly. The second sidewall 12 is located rearward of the first side portion, facilitating rearward spraying of water from the first water spray port 10b. For example, in one embodiment, the first water spray port 10b sprays a mixed detergent solution onto the laundry within the laundry treatment chamber.

[0058] In some embodiments, the second side wall 12 extends obliquely from the radially outer side to the radially inner side of the door sealing ring 200 toward the first side wall 13 , which facilitates the first water spray port 10b to spray water obliquely downward toward the rear of the barrel assembly.

[0059] In some embodiments, the spray head unit 100 further includes a guide portion 60 disposed on the second sidewall 12 and extending away from the shell 10. The guide portion 60 includes a flow channel 60a that communicates with the first spray port 10b. Fluid ejected from the first spray port 10b is discharged from the spray head unit 100 through the flow channel 60a. The guide portion 60 guides the fluid passing through it, preventing it from flowing along the outer wall of the shell 10 and instead allowing it to be concentrated and delivered to the barrel assembly.

[0060] For example, in one embodiment, the fluid sprayed out from the first water spray port 10b is a detergent mixed solution, and the detergent ingredients cause it to carry more foam. When the fluid is sprayed out through the first water spray port 10b, the foam with a lighter texture can also move along the extension direction of the guide channel 60a, thereby reducing the accumulation of foam on the outer wall of the shell 10.

[0061] For some examples, see Figure 2 Along the flow direction of the fluid, the flow cross-sectional area of ​​the guide channel 60a gradually increases. In this way, when the fluid flies through the internal space of the guide channel 60a, the inner wall of the guide channel 60a has almost no effect on the water outlet form of the fluid, so that the fluid sprayed from the first water outlet 10b can maintain its original motion state and enter the cylinder assembly.

[0062] In some embodiments, the first sidewall 13 and the second sidewall 12 extend radially toward the inside of the door seal 200, extending in an inclined direction toward each other. In other words, the cross-sections of the first cavity 10A and the second cavity 10B gradually decrease from the radially outer side of the door seal 200 to the radially inner side. This allows for a higher water pressure on the side of the cavity closer to the bottom wall 15, resulting in a higher flow rate for the fluid discharged from the first water outlet 10b.

[0063] For some examples, see Figure 4 and Figure 8 The at least one water outlet includes a spray outlet 10e, and at least one end plate 11 is provided with a spray outlet 10e for spraying water toward the door seal 200. The end plates 11 are located at both ends of the housing 10 along the circumference of the door seal 200, facilitating the spray outlets 10e disposed thereon to spray water toward the interior of the door seal 200. Exemplarily, the fluid sprayed from the spray outlet 10e is clean water, which cleans the door seal 200, minimizing detergent residue after the laundry treatment device has finished operating, thereby reducing microbial growth.

[0064] In some embodiments, the bottom wall 15 is provided with a water spray port for spraying water toward the door glass bowl. The fluid discharged from the water spray port on the bottom wall 15 can flow downward onto the door glass bowl. For example, the fluid sprayed from the water spray port on the bottom wall 15 is clean water, which can clean the door glass bowl and facilitate the user to see the interior of the laundry treatment chamber through the door glass bowl.

[0065] In some embodiments, a water inlet is provided on the top wall 14. Compared to the rest of the housing 10, the top wall 14 is closer to the outside of the door seal 200. The water inlet provided on the top wall 14 is convenient for piping.

[0066] 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 detergents 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, which is then delivered to housing 10 via a pipe connected to the water inlet.

[0067] For some examples, see Figure 6The at least one cavity includes a first cavity 10A and a second cavity 10B that are not interconnected. This means that the fluid in the first cavity 10A does not flow into the second cavity 10B, and the fluid in the second cavity 10B does not flow into the first cavity 10A. The at least one water inlet includes a first water inlet 10a and a second water inlet 10c, and the at least one water outlet includes a first water outlet 10b and a second water outlet 10d.

[0068] For example, see Figure 6 The shell 10 includes a first spacing structure 20 , which is disposed inside the shell 10 and separates the space inside the shell 10 into at least a first cavity 10A and a second cavity 10B.

[0069] At least one water channel includes a first water channel 300A and a second water channel 300B. The first water channel 300A connects the water source to the first water inlet 10a, while the second water channel 300B connects the water source to the second water inlet 10c. The first chamber 10A connects the first water inlet 10a to the first water outlet 10b, while the second chamber 10B connects the second water inlet 10c to the second water outlet 10d. Specifically, the first water channel 300A delivers fluid to the first chamber 10A through the first water inlet 10a, and the fluid in the first chamber 10A is ejected through the first water outlet 10b. The second water channel 300B delivers fluid to the first chamber 10A through the second water inlet 10c, and the fluid in the second chamber 10B is ejected through the second water outlet 10d. 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 channels with different functional purposes in the clothing processing equipment, so that the nozzle unit 100 can release fluids with different functions into the clothing processing cavity, which is beneficial to improving the integration of the nozzle unit 100.

[0070] For example, if the fluid in the second water channel 300B is clean water, the fluid sprayed out by the second water spray port 10d may also be clean water. As an optional embodiment, the second water spray port 10d includes a spray port 10e.

[0071] The water source referred to in this specification can be the water supply device of the laundry processing apparatus, such as a water inlet valve, or the outlet of a circulation pump that pumps water from the drum assembly into the first water path 300A or the second water path 300B. Clean water is not limited to tap water; it refers to a fluid with a lower concentration of detergent components than a detergent mixture.

[0072] For example, in one embodiment, the second water spray port 10d 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 convenient to spray water toward the door glass bowl.

[0073] Illustratively, in one embodiment, the second water spray port 10d includes a spray port 10e, which is provided at a portion of the end plate 11 corresponding to the second cavity 10B. Thus, when the spray head assembly is installed in place, it is beneficial to spray water toward the door seal 200.

[0074] For example, in one embodiment, the portion of the bottom wall 15 corresponding to the second cavity 10B and the portion of the end plate 11 corresponding to the second cavity 10B are respectively provided with second water spraying ports 10d, which can expand the spraying range and improve the effect.

[0075] In some embodiments, the at least one water channel further includes a third water channel 300C, wherein the fluid in the third water channel 300C is clean water. There are at least two first water spray outlets 10b, with the first water channel 300A connecting the water source and one of the first water inlets 10a, and the third water channel 300C connecting the water source and the other first water inlet 10a. It will be appreciated that the fluid in the first water channel 300A and the fluid in the third water channel 300C mix within the first chamber 10A. The convergence of the two fluids with different compositions can promote the dissolution and mixing of the detergent. The first water spray outlet 10b is used to dispense a mixture of the detergent solution and clean water into the drum assembly, facilitating sufficient contact between the detergent and the laundry to be treated, thereby enhancing the cleaning effect.

[0076] For example, in one embodiment, please refer to 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 outlet of 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. 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 outlet, it draws fluid near the outlet, enhancing mixing and foaming effects.

[0077] As an optional embodiment, the nozzle 40 is connected to the water inlet of the second water channel 300B, and the fluid in the second water channel 300B is clean water. The fluid flow rate at the outlet of the nozzle 40 is higher, and the impact effect is more significant. The following description also uses the example of the nozzle 40 being connected to the water inlet of the second water channel 300B and the fluid in the second water channel 300B being clean water.

[0078] For some examples, see Figure 6The 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.

[0079] 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.

[0080] 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.

[0081] 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 forms.

[0082] 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.

[0083] 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.

[0084] In some embodiments, the spray head unit 100 further includes at least one connector pipe, one for each water inlet. The shell 10 is located radially inward of the door seal 200, and the connector pipe radially extends through the door seal. Fluid can enter the shell 10 through the connector pipe, and the connector pipe also serves as a position limiter for the shell 10, securing it circumferentially relative to the door seal 200.

[0085] 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 has a tendency to flow toward the lower left part or the lower right part of the door sealing ring 200.

[0086] The above-mentioned upper left portion refers to an area located on the left side of the door sealing ring and whose height is not lower than the center of the door sealing ring. The above-mentioned upper right portion refers to an area located on the right side of the door sealing ring and whose height is not lower than the center of the door sealing ring.

[0087] For example, in one embodiment, the laundry processing apparatus includes a drying tunnel assembly. A detergent supply assembly is located in the upper left or upper right portion of the laundry processing apparatus, above the door seal 200, and is used to deliver a mixed detergent solution to the spray head unit 100 via the first water channel 300A. A drying tunnel body is also located above the door seal 200 and at the top of the laundry processing apparatus, and is used to circulate air within the drum assembly through the air inlet on the door seal 200 to dry the laundry. Positioning the spray head unit 100 in the upper left or upper right portion of the door seal 200 facilitates piping installation and avoids the need for the drying tunnel assembly.

[0088] For example, in one embodiment, the at least one joint pipe includes a first joint pipe 51, a second joint pipe 52, and a third joint pipe 53. There are at least two first water inlet 10a, with the first and second joint pipes 51, 52 respectively connected to the first water inlet 10a, and the third joint pipe 53 connected to the second water inlet 10c. The first waterway 300A can flow through the first joint pipe 51, the second waterway 300B can flow through the second joint pipe 52, and the third waterway 300C can flow through the third joint pipe 53.

[0089] For example, in one embodiment, the first joint pipe 51 , the second joint pipe 52 and the third joint pipe 53 are arranged along the circumference of the door sealing ring 200 , and are all provided on the top wall 14 of the shell 10 .

[0090] For some examples, see Figure 6The first joint tube 51, the second joint tube 52 and the third joint tube 53 are located in the same plane along the center lines of their respective extension directions, and from the shell 10 to the direction away from the shell 10, the first joint tube 51, the second joint tube 52 and the third joint tube 53 are bent to the same side.

[0091] That is, the first joint pipe 51, the second joint pipe 52, and the third joint pipe 53 are arranged side by side and extend in the same direction, which facilitates centralized pipe routing. Bending toward the same side facilitates avoiding other structures of the laundry processing device during installation. Of course, in other embodiments, the first joint pipe 51, the second joint pipe 52, and the third joint pipe 53 can all be straight pipes without bends, or each can be composed of straight pipes connected in multiple directions, with the straight pipes connected by elbows at the junction.

[0092] In some embodiments, 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 .

[0093] 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 .

[0094] 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.

[0095] 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.

[0096] As an optional embodiment, the top wall 14 of the shell 10 and the first, second, and third joint tubes 51, 52, and 53 can be a one-piece structural component. The nozzle 40 is mounted on the top wall 14 of the shell 10. The bottom wall 15 of the shell 10, the first and second side walls 13, 12, and the two end plates 11 are also one-piece structural components. The guide portion 60 can be formed into a one-piece structural component with the second side wall 12 through a two-color injection molding process.

[0097] 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.

[0098] 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.

[0099] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.
