[0029] 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.

[0030] In the description of the embodiments of the present application, it should be noted that the terms "upper," "lower," "front," "back," "left," "right," "inner," "outer," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the embodiments of the present application and to simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be construed as limiting the embodiments of the present application. In addition, the terms "first," "second," etc., etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] The embodiment of the present application provides a nozzle unit 200 for a clothes processing device, see Figure 4 and Figure 6 The nozzle unit 200 includes a first joint pipe 204 , a second joint pipe 205 , and a shell 201 .

[0035] The embodiment of the present application further provides a clothes processing device, which includes a clothes processing chamber and a spray head unit 200 in any embodiment of the present application. The spray head unit 200 is used to put a detergent mixed solution into the clothes processing chamber.

[0036] The form of the clothes processing device is not limited, for example, a drum washing machine, a pulsator washing machine, a drum washer-dryer, a pulsator washer-dryer, etc. This specification takes a drum washing machine as an example for description.

[0037] The laundry processing chamber is used to accommodate the laundry to be processed. For example, in some embodiments, Figure 1As shown, the clothing processing device includes a barrel assembly 10 and a door sealing ring 60. The door sealing ring 60 is arranged on the front side of the barrel assembly 10. The interior of the barrel assembly 10 and the connecting space on the radial inner side of the door sealing ring 60 constitute a clothing processing chamber (not shown in the figure).

[0038] The shower head unit 200 includes a first water channel 40A and a second water channel 50A. The first joint pipe 204 constitutes a portion of the first water channel 40A, and the second joint pipe 205 constitutes a portion of the second water channel 50A.

[0039] It should be noted that the first waterway 40A refers to the flow path of the fluid, not specifically a pipe-type structure, and the second waterway 50A refers to the flow path of the fluid, not specifically a pipe-type structure, that is, there is a space in the nozzle unit 200 for fluid flow. The first waterway 40A and the second waterway 50A are two fluid flow paths with different directions, please refer to Figures 1 to 8 , the dotted lines with arrows in the accompanying drawings indicate the flow direction of the fluid.

[0040] The fluid in the first water channel 40A is a detergent mixed solution, that is, the detergent mixed solution is passed into the first joint pipe 204. Figures 1 to 8 The dashed arrow lines in the accompanying drawings indicate the direction of fluid flow. The source of the fluid in first waterway 40A may be a detergent dispenser of a laundry processing device. For example, in some embodiments, the detergent dispenser includes a detergent dispenser chamber into which a user can dispense the detergent required for washing. The detergent dissolves in water to form a mixed detergent solution, which then flows into first waterway 40A.

[0041] The fluid in the second water channel 50A is not limited and can be tap water or a fluid containing a detergent component. For example, in some embodiments, the laundry processing apparatus further includes a circulation pump that pumps the fluid contained in the laundry processing chamber into the second water channel 50A. In other embodiments, the laundry processing apparatus further includes a water inlet valve 90, and a first outlet 90a of the water inlet valve 90 supplies tap water into the second water channel 50A.

[0042] It should be noted that the detergent mixed solution mentioned in this specification is merely for convenience of description and refers to a mixed solution containing dissolved detergent. Its mass percentage concentration is not limited, and it does not necessarily mean that the detergent is completely dissolved. The detergent can be in any form and can be powdered laundry detergent, liquid laundry detergent, or softener.

[0043] See also Figure 4The shell 201 has a water outlet 201b, and a first joint pipe 204 and a second joint pipe 205 are respectively connected to the shell 201. The first joint pipe 204 and the second joint pipe 205 are spaced apart along a first direction R. That is, the first joint pipe 204 and the second joint pipe 205 are arranged side by side with a certain distance between them. The first direction R can be oriented in any direction (for example, perpendicular to the radial direction of the door seal 60). This reserves installation space for the first joint pipe 204 and the second joint pipe 205.

[0044] The fluids in the first water channel 40A and the second water channel 50A meet in the shell 201 and are discharged into the laundry processing chamber of the laundry processing apparatus through the water outlet 201 b.

[0045] The aforementioned delivery into the clothing treatment chamber means that the mixed fluid ejected from the water outlet 201b does not need to be guided by other structures, but is instead directly sprayed into the clothing treatment chamber due to inertia. This not only eliminates the need for a drainage pipeline downstream of the water outlet 201b, but also eliminates the need for the drainage pipeline to regulate the fluid shape. This helps the fluid ejected from the water outlet 201b maintain its existing outlet shape. The fluid ejected from the water outlet 201b diffuses outward, spraying the clothes to be treated in the clothing treatment chamber and improving the cleaning effect.

[0046] The first joint pipe 204 can serve as the mounting structure for connecting the spray head unit 200 to the laundry treatment device, and the second joint pipe 205 can serve as the mounting structure for connecting the spray head unit 200 to the laundry treatment device. For example, the first waterway 40A and the second waterway 50A are each composed of one or more sections of conduit, with one section of the conduit connected to the first joint pipe 204 and another section of the conduit connected to the second joint pipe 205, thereby allowing fluid to flow into the spray head unit 200.

[0047] In the embodiment of the present application, the nozzle unit 200 introduces two fluids through the first joint pipe 204 and the second joint pipe 205. The two fluids impact and mix in the nozzle unit 200, promoting the dissolution of the detergent in the fluids. The mixed fluid is then discharged into the clothing treatment chamber through the water outlet, improving the cleaning effect. The structure of the nozzle unit 200 facilitates the mixing of fluids and is easy to install.

[0048] It should be noted that the extension directions of the first joint pipe 204 and the second joint pipe 205 are not limited, and the extension directions of the two can be the same or different. As an optional embodiment, the extension directions of the first joint pipe 204 and the second joint pipe 205 are the same and both perpendicular to the first direction R.

[0049] The spray head unit 200 can be mounted on the door seal 60 of the laundry processing device. For example, in some embodiments, see Figure 1The first and second joint pipes 204 and 205 pass through the door seal 60, and the shell 201 is located radially inward of the door seal 60. In other words, the door seal 60 provides mounting support for the spray head unit 200. The spray head unit 200 is positioned there to facilitate the fluid ejected from the water outlet 201b to be sprayed onto the clothing to be treated, achieving a showering effect.

[0050] In some embodiments, the spray head unit 200 further includes a baffle 203, which surrounds the outer circumference of the housing 201 near one end of the first joint tube 204 and the second joint tube 205. The baffle 203 is configured to abut against the clothing processing device along the extension direction of the first joint tube 204 or the second joint tube 205, thereby limiting movement of the spray head unit 200 along the extension direction of the first joint tube 204 (or the second joint tube 205) and serving as a stop and positioning mechanism. For example, in an embodiment where the spray head unit 200 is mounted on a door seal 60, the baffle 203 abuts against the radially inner side of the door seal 60.

[0051] For some examples, see Figure 7 and Figure 8 The shell 201 extends along a first direction R that intersects the centerline of the door seal 60. In this embodiment, the first joint pipe 204 and the second joint pipe 205 are arranged side by side approximately tangentially to the door seal 60, thereby reducing space occupied by the structure in the front-to-back direction. The spray head unit 200 is fixed to the door seal 60 at least radially via the first joint pipe 204 and the second joint pipe 205.

[0052] It can be understood that the shell 201 extends along the first direction R. After the fluid in the first joint tube 204 or the second joint tube 205 enters the shell 201, the fluid state of at least one of them is directly changed, extending its time inside the shell 201 so that it can fill the interior of the shell 201, so that the two fluids can be fully mixed.

[0053] For some examples, see Figure 8 The clothes processing device includes a turbulent flow structure 21 , which is provided in the second joint pipe 205 and is used to provide a circumferential velocity component to the fluid in the second joint pipe 205 .

[0054] The circumferential velocity component provided above refers to the fluid in the second joint pipe 205 after passing through the turbulent structure 21 , whose velocity component in the circumferential direction of the second joint pipe 205 is not zero, and the circumferential direction of the second joint pipe 205 is perpendicular to the extension direction of the second joint pipe 205 .

[0055] In this embodiment, the turbulent structure 21 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 connecting pipe 205, it facilitates the fluid to diffuse in a conical shape, with a wider radiation range and better visual effect.

[0056] Exemplarily, the turbulent flow structure 21 includes one or more spiral blades, which divide at least a partial length section of the second joint pipe 205 where the spiral blades are located into a plurality of sub-flow channels.

[0057] The above-mentioned multiple refers to the number of blades being multiple, which can be two, three or more, that is, the number of heads of the spiral is not less than two, and does not limit the number of turns of the spiral.

[0058] After the fluid passes through the spiral blades, it exhibits a spiral motion. The spiral blades have a simple structure, good flow disturbance effect on the fluid, and low resistance, reducing energy loss when the fluid passes through.

[0059] For some examples, see Figure 5 and Figure 8 The nozzle unit 200 includes a nozzle 202, which is arranged inside the shell 201. One end of the nozzle 202 is connected to the second joint pipe 205, and the other end of the nozzle 202 has an outlet, which is used to spray water toward the water outlet 201b, so that the nozzle 202 can suck the fluid from the first water channel 40A when spraying water toward the water outlet 201b, and use the fluid sprayed by the nozzle 202 to drive the mixed fluid in the shell 201 to be sprayed out from the water outlet 201b.

[0060] The above-mentioned suction of the fluid from the first water channel 40A means that while the fluid ejected from the nozzle 202 flows toward the water outlet 201b, under the action of the viscosity of the fluid and the flow rate difference, the fluid from the first water channel 40A is concentrated toward the water outlet 201b, thereby improving the mixing effect of the fluid in the first water channel 40A and the fluid in the second water channel 50A, enhancing the mixing and foaming effects, and promoting the dissolution of the detergent.

[0061] In addition, the outlet of the mouth 202 sprays water toward the water outlet 201b, and the water outlet shape of the water outlet 201b is similar to the water outlet shape of the mouth 202. There is no need to set an additional drainage pipe at the water outlet 201b to achieve the spraying effect on the clothes to be processed in the clothing processing chamber.

[0062] For some examples, see Figure 8 A diameter-reducing section 22 is formed inside the mouth 202 to increase the flow rate of the fluid ejected from the mouth outlet.

[0063] The position of the reduced diameter section 22 within the nozzle 202 is not limited. For example, in some embodiments, the end of the reduced diameter section 22 forms the outlet of the nozzle 202. In other words, the fluid in the second connector tube 205 is ejected from the end of the reduced diameter section 22. In other embodiments, the end of the reduced diameter section 22 is further connected to a constant diameter section and / or an expanded diameter section, which form the outlet of the nozzle 202.

[0064] It should be noted that, along the direction of fluid movement, the flow area of ​​the fluid in the above-mentioned diameter-reducing section 22 becomes smaller, the flow area in the above-mentioned diameter-equalizing section remains basically unchanged, and the flow area in the above-mentioned diameter-expanding section becomes larger.

[0065] The reduced diameter section 22 can increase the impact force of the fluid by limiting the flow area when the fluid is ejected, thereby generating a greater impact force on the fluid in the shell 201 and achieving a better mixing effect.

[0066] At the same time, the reduced diameter section 22 makes the outlet of the mouth 202 have a greater injection speed, which can generate obvious negative pressure in a relatively large area around it, so that the fluid in the shell 201 is sucked in under the action of the negative pressure and mixed with the fluid ejected from the mouth 202, thereby improving the mixing and foaming effects.

[0067] The nozzle unit 200 of the embodiment of the present application can be a one-piece component, that is, the shell 201, nozzle 202, baffle 203, first joint pipe 204, and second joint pipe 205 are integrally formed, for example, by injection molding. Of course, the nozzle unit 200 can also be a separate component that can be assembled after processing.

[0068] For some examples, see Figure 8 The interior of the shell 201 has a guide channel 201a and a mixing space 20a. The guide channel 201a extends along the first direction R. The mixing space 20a is arranged at one end of the guide channel 201a close to the second joint pipe 205. One end of the guide channel 201a is connected to the first joint pipe 204, and the other end is connected to the mixing space 20a. The mouth 202 is arranged in the mixing space 20a.

[0069] The extending direction of the guide channel 201 a is the same as the extending direction of the shell 201 .

[0070] Different from the first water channel 40A or the second water channel 50A, in the mixing space 20a, the two fluids flowing into the nozzle unit 200 affect each other, and the flow state (including flow velocity, flow direction or density, etc.) of the fluid changes after entering the mixing space 20a.

[0071] It can be understood that the fluid in the first water channel 40A and the fluid in the second water channel 50A are mixed in the mixing space 20a, and the guide channel 201a guides the fluid from the first water channel 40A sprayed out by the first connecting pipe 204 to the nozzle 202, so that the two are concentrated in the mixing space 20a for mixing, thereby improving the mixing efficiency.

[0072] For some examples, see Figure 7 and Figure 8 , along the direction of fluid movement, the flow cross-section of the flow guide channel 201a gradually increases.

[0073] It will be appreciated that the end of the diversion channel 201a near one end of the mixing space 20a has the largest flow cross-section. When the fluid enters the shell 201, guided by the diversion channel 201a, it tends to concentrate toward the end near the mixing space 20a, allowing it to fill the mixing space 20a as much as possible and mix thoroughly with the fluid at the outlet end of the second joint pipe 205. This also reduces the velocity of the fluid in the diversion channel 201a as it enters the mixing space 20a, making the impact of the fluid ejected from the second joint pipe 205 more pronounced.

[0074] In some embodiments, the water outlet cross-sectional area of ​​the diversion channel 201a is larger than the water outlet cross-sectional area of ​​the mouth 202, and smaller than the water outlet cross-sectional area of ​​the water outlet 201b.

[0075] For some examples, see Figure 7 The water outlet cross-section of flow channel 201a (referenced at position y) is larger than the water outlet cross-section of nozzle 202 (referenced at position x), and smaller than the water outlet cross-section of outlet 201b (referenced at position z). This effectively suppresses backflow caused by a large flow difference between first joint pipe 204 and second joint pipe 205, effectively preventing the fluid in mixing space 20a from flowing back into first joint pipe 204.

[0076] In addition, the area of ​​the water outlet cross-section at the water outlet end of the first water channel 40A is larger than the area of ​​the water outlet cross-section at the water outlet end of the second water channel 50A, so that when the detergent mixed solution enters the mixing space 20a from the first water channel 40A, the detergent components within the unit volume have a larger contact area with the fluid in the mixing space 20a, which is conducive to more uniform mixing and more complete dissolution of the detergent components.

[0077] In some embodiments, the water outlet 201b is used to spray water obliquely downward toward the rear side of the laundry processing chamber.

[0078] That is, see Figure 5Water outlet 201b sprays water downward and rearward. The fluid at water outlet 201b has both a downward velocity component and a velocity component along the axial rearward direction of the laundry treatment chamber. That is, the centerline n of water outlet 201b forms an acute angle φ with the reference plane m. Reference plane m is perpendicular to the axis of the laundry treatment chamber. This spraying of the detergent mixture onto the laundry increases the contact area between the detergent and the laundry, improving the laundry treatment efficiency of the laundry treatment device.

[0079] The value of acute angle φ is not limited. For example, the acute angle φ formed by the centerline n of the water outlet 201b and the reference plane m is 30° to 70°, i.e., 30°≤φ≤70°. Examples include 30°, 45°, 50°, 60°, 70°, etc. This allows the fluid ejected from the water outlet 201b to be sprayed onto the clothing in the laundry treatment chamber as much as possible, quickly soaking the clothing, improving detergent utilization, and enhancing the cleaning effect.

[0080] For example, see Figure 5 The shell 201 includes a first end wall 2011 and a second end wall 2012. The water outlet 201b is formed on the first end wall 2011. The first joint pipe 204 and the second joint pipe 205 are both connected to the second end wall 2012. From the second end wall 2012 to the first end wall 2011, the shell 201 bends toward the rear side of the clothing processing chamber, and the first end wall 2011 is inclined toward the lower rear side of the clothing processing chamber.

[0081] In this embodiment, the shell 201 not only forms a chamber for fluid movement but also serves to redirect and guide the fluid's movement. The curvature of the shell 201 facilitates transitions between different fluid flow directions. For example, in an embodiment where both the first joint tube 204 and the second joint tube 205 extend radially of the door seal 60, the curvature of the shell 201 allows the fluid to transition from a radial flow upon entering the shell 201 to an oblique, downward flow toward the rear of the laundry treatment chamber upon exiting.

[0082] As an alternative embodiment, see Figure 5 and Figure 8 The baffle 203 surrounds the outer periphery of the second end wall 2012 , and the baffle 203 and the second end wall 2012 are integrally formed.

[0083] For some examples, see Figure 5 and Figure 6The shell 201 includes a first side wall 2013, a second side wall 2014 and a transition connecting wall 2015. The first side wall 2013 is located on the convex side of the bending direction of the shell 201, and the second side wall 2014 is located on the concave side of the bending direction of the shell 201. The first side wall 2013 and the second side wall 2014 are connected at opposite ends along the first direction R by the transition connecting wall 2015.

[0084] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0085] 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.
