In this specification, the schematic descriptions of the above terms do not necessarily refer to the same embodiment or example.

[0037] The embodiments of the present application provide a spray head unit 200 for a clothing treatment device. Please refer to Figure 1 、 Figure 2 and Figure 3, the spray head unit 200 includes a mixing space 20a and a water outlet 201b. The water outlet 201b is provided on the wall surface of the mixing space 20a. There are a first waterway 40A and a second waterway 50A for conveying fluid in the spray head unit 200.

[0038] The embodiment of the present application further provides a laundry treatment device, including a laundry treatment cavity and the spray head unit 200 of any embodiment of the present application. The spray head unit 200 is used to spray the mixed fluid in the mixing space 20a to the laundry treatment cavity through the water outlet 201b. The form of the laundry treatment device is not limited. For example, it can be a drum washing machine, a pulsator washing machine, a drum washing and drying integrated machine, a pulsator washing and drying integrated machine, etc. This specification takes a drum washing machine as an example for illustration.

[0039] The laundry treatment cavity of the laundry treatment device is used to accommodate the laundry to be treated. Exemplarily, in one embodiment, the laundry treatment device includes a cylinder assembly 10 and a door seal 60. The door seal 60 is arranged on the front side of the cylinder assembly 10. The communication space formed between the inside of the cylinder assembly 10 and the radial inner side of the door seal 60 constitutes the laundry treatment cavity.

[0040] It should be noted that the first waterway 40A refers to the flow path of the fluid and does not specifically refer to a pipe structure. The second waterway 50A refers to the flow path of the fluid and does not specifically refer to a pipe structure. The first waterway 40A and the second waterway 50A are two fluid flow paths with different directions. Please refer to Figures 1 to 8 , and the dotted lines with arrows in the drawings all indicate the flow direction of the fluid.

[0041] The fluid in the first waterway 40A converges with the fluid in the second waterway 50A in the mixing space 20a. That is to say, the spray head unit 200 has an inlet for the first waterway 40A to introduce fluid into the mixing space 20a, and also has an inlet for the second waterway 50A to introduce fluid into the mixing space 20a. The first waterway 40A and the second waterway 50A introduce their respective fluids into the mixing space 20a for mixing.

[0042] Different from in the first waterway 40A or the second waterway 50A, in the mixing space 20a, the two fluids affect each other, and the flow state (including flow velocity, flow direction, density, etc.) of the fluid changes after entering the mixing space 20a. The mixed fluid in the mixing space 20a is sprayed to the laundry treatment cavity of the laundry treatment device through the water outlet 201b, and the water outlet 201b is provided on the wall surface of the mixing space 20a. That is to say, the two fluids are directly put into use after mixing, and there is no need to set an additional pipe structure at the water outlet 201b. When the fluids are mixed, the air in the external environment is more likely to enter the mixing space 20a from the water outlet 201b.

[0043] The fluid in the first waterway 40A is a detergent mixed solution. The source of the fluid in the first waterway 40A can be the detergent dispensing device of the laundry treatment equipment. For example, in some embodiments, the detergent dispensing device has a detergent dispensing chamber, and the detergent required for washing is dispensed into the detergent dispensing chamber. The detergent dissolves in water to form a detergent mixed solution and flows into the first waterway 40A.

[0044] It should be noted that the detergent mixed solution mentioned in this specification is only for convenient description, referring to the mixed solution in which the detergent is dissolved, and its mass percentage concentration is not limited, nor is it limited that the detergent is completely dissolved. The form of the detergent is not limited, and it can be powdered washing powder, or liquid laundry detergent or fabric softener that can flow, etc.

[0045] The fluid in the second waterway 50A is not limited. It can be tap water or a fluid in which detergent components are dissolved. For example, in some embodiments, the laundry treatment equipment further includes a circulation pump, and the circulation pump pumps the fluid contained in the laundry treatment chamber into the second waterway 50A; in other embodiments, the laundry treatment equipment further includes a water inlet valve 90, and the first outlet 90a of the water inlet valve 90 supplies tap water into the second waterway 50A.

[0046] Please refer to Figure 7 , the water outlet ends of the first waterway 40A and the second waterway 50A are located in the spray head unit 200. A diversion channel 201a is provided at the water outlet end of either the first waterway 40A or the second waterway 50A, and the diversion channel 201a is used to direct the fluid towards the water outlet end of the other.

[0047] The above-mentioned directing the fluid towards the water outlet end of the other means that after the fluid in the first waterway 40A or the second waterway 50A flows out from the diversion channel 201a, it immediately converges with the fluid at the water outlet end of the other, so as to minimize the distance between the water outlet end of the first waterway 40A and the water outlet end of the second waterway 50A.

[0048] In the spray head unit 200, the diversion channel 201a brings the water outlet ends of the first waterway 40A and the second waterway 50A closer to each other. The fluid in the first waterway 40A is mixed with the fluid sprayed from the second waterway 50A immediately after being sprayed. In this way, by using the impact force when the fluid is sprayed, the mixing effect of the two fluids is improved, thereby promoting the dissolution of the detergent and improving the washing ratio.

[0049] In some embodiments, please refer to Figure 7 and Figure 8 , the water outlet direction of the water outlet end of the second waterway 50A faces the water outlet 201b, the diversion channel 201a is formed at the water outlet end of the first waterway 40A, and the water outlet direction of the diversion channel 201a intersects with the water outlet direction of the second waterway 50A.

[0050] It can be understood that the diversion channel 201a guides the fluid to the vicinity of the water outlet end of the second waterway 50A. After the fluid in the second waterway 50A is ejected, it converges with the fluid in the first waterway 40A and largely maintains the original water outlet form, driving the mixed fluid to be ejected from the water outlet 201b. Thus, there is no need to set up additional pipelines or pressurization structures, making the water spraying form at the water outlet 201b relatively close to the water outlet form of the second waterway 50A. By utilizing the fluid impact force at the water outlet end of the second waterway 50A, the spraying effect at the water outlet 201b can be improved.

[0051] In some embodiments, please refer to Figure 8 , along the direction of fluid movement, the cross-sectional area of the flow-through section of the diversion channel 201a gradually increases.

[0052] It should be noted that the cross-sectional area of the end of the diversion channel 201a close to the mixing space 20a is the largest. Under the guidance of the diversion channel 201a, the fluid therein has a tendency to concentrate towards the end close to the mixing space 20a, making it as full of the mixing space 20a as possible and fully mixing with the fluid at the water outlet end of the other waterway.

[0053] In some embodiments, the flow rate at the water outlet end of the first waterway 40A is less than the flow rate at the water outlet end of the second waterway 50A, and the diversion channel 201a is formed at the water outlet end of the first waterway 40A. That is, the diversion channel 201a guides the fluid with a slower flow rate to the fluid with a faster flow rate, thereby utilizing the impact force when the second waterway 50A with a faster flow rate discharges water, enabling it to fully mix with the fluid in the first waterway 40A and enhancing the foaming effect of the detergent.

[0054] As an optional embodiment, in the embodiment where the flow rate at the water outlet end of the first waterway 40A is less than the flow rate at the water outlet end of the second waterway 50A, along the direction of fluid movement, the cross-sectional area of the flow-through section of the diversion channel 201a gradually increases. In this way, the flow rate of the fluid in the first waterway 40A slows down in the diversion channel 201a, the flow rate difference between the water outlet ends of the first waterway 40A and the second waterway 50A is greater, the impact effect of the fluid in the second waterway 50A on the fluid in the first waterway 40A is better, and the mixing effect is better.

[0055] In some embodiments, please refer to Figure 7 , the area of the water outlet cross-section (reference y) of the diversion channel 201a is larger than the area of the water outlet cross-section (reference x) at the water outlet end of the second waterway 50A and smaller than the area of the water outlet cross-section (reference z) at the water outlet 201b.

[0056] In this way, the backflow phenomenon caused by an excessive flow rate difference between the first waterway 40A and the second waterway 50A can be effectively suppressed, that is, the fluid in the mixing space 20a is prevented from flowing back into the first waterway 40A as much as possible. In addition, the area of the water outlet cross-section at the water outlet end of the first waterway 40A is larger than the area of the water outlet cross-section at the water outlet end of the second waterway 50A. When the detergent mixed solution enters the mixing space 20a from the first waterway 40A, the detergent component per unit volume has a larger contact area with the fluid in the mixing space 20a, which is beneficial to more uniform mixing of the detergent component and more sufficient dissolution.

[0057] In some embodiments, please refer to Figure 8 , a reduced-diameter section 22 is provided at the end of the second waterway 50A to increase the flow velocity at the water outlet end of the second waterway 50A.

[0058] Exemplarily, in some embodiments, the end of the reduced-diameter section 22 forms the water outlet end of the second waterway 50A. That is, the fluid in the second waterway 50A is ejected from the end of the reduced-diameter section 22. In other embodiments, an equal-diameter section and / or an enlarged-diameter section are further connected to the end of the reduced-diameter section 22, and the equal-diameter section and / or the enlarged-diameter section form the water outlet end of the second waterway 50A.

[0059] It should be noted that along the direction of fluid movement, the flow-through area of the fluid in the above-mentioned reduced-diameter section 22 becomes smaller, the flow-through area in the above-mentioned equal-diameter section remains basically unchanged, and the flow-through area in the above-mentioned enlarged-diameter section becomes larger.

[0060] By restricting the flow-through area when the fluid is ejected, the reduced-diameter section 22 can increase the impact force of the fluid, generate a relatively large impact force on the fluid at the water outlet end of the first waterway 40A, and achieve a better mixing effect.

[0061] At the same time, the reduced-diameter section 22 enables the water outlet end of the second waterway 50A to have a relatively large ejection speed, which can generate an obvious negative pressure in a relatively large surrounding area, so that the fluid at the water outlet end of the first waterway 40A is sucked under the action of the negative pressure and mixed with the fluid in the second waterway 50A, improving the mixing and foaming effects.

[0062] In some embodiments, please refer to Figure 8 , the laundry treatment device includes a turbulent flow structure 21, and the turbulent flow structure 21 is arranged in the second waterway 50A to provide a circumferential velocity component for the fluid in the second waterway 50A.

[0063] The above-mentioned provision of the circumferential velocity component means that for the fluid in the second waterway 50A after passing through the turbulent flow structure 21, the component of its velocity direction in the circumferential direction of the second waterway 50A is not zero, and the circumferential direction of the second waterway 50A is perpendicular to the extension direction of the second waterway 50A.

[0064] In this embodiment, the turbulent flow structure 21 enables some of the fluid to have both a circumferential movement speed and a speed of continuing to flow forward. Therefore, some of the fluid moves in a spiral shape approximately. When the fluid is ejected from the water outlet end of the second waterway 50A, it is convenient for the fluid to diffuse in a conical shape, with a wider radiation range and better visual effect.

[0065] Exemplarily, the turbulent flow structure 21 includes one or more spiral vanes, and the spiral vanes divide at least a partial length section of the second waterway 50A where they are located into a plurality of sub-channels.

[0066] The above-mentioned "a plurality" means that the number of vanes is a plurality, which can be two, three or more. That is, the number of starts of the spiral line is not less than two, and it does not limit the number of turns of the spiral line.

[0067] After the fluid passes through the spiral vanes, it presents a spiral movement. The spiral vane structure is simple, has a good turbulent flow effect on the fluid, and has a small resistance, reducing the energy loss when the fluid passes through.

[0068] In some embodiments, the water outlet 201b is used to spray water obliquely downward towards the rear side of the laundry treatment chamber of the laundry treatment device. That is, please refer to Figure 5 , the water outlet 201b sprays water backward and downward. The fluid at the water outlet 201b has both a downward velocity component and a velocity component along the axial rear side of the laundry treatment chamber. That is, the center line n of the water outlet 201b forms an acute angle φ with the reference plane m. Among them, the reference plane m is perpendicular to the axis of the laundry treatment chamber.

[0069] The value of the acute angle φ is not limited. Exemplarily, the acute angle φ formed by the center line n of the water outlet 201b and the reference plane m is 30° to 70°, that is, 30° ≤ φ ≤ 70°. For example, 30°, 45°, 50°, 60°, 70°, etc. In this way, the fluid ejected from the water outlet 201b can be sprayed on the laundry in the laundry treatment chamber as much as possible, quickly wetting the laundry, improving the utilization rate of the detergent, and enhancing the washing effect.

[0070] In some embodiments, please refer to Figure 8 , the spray head unit 200 includes a housing portion 201. The housing portion 201 extends along the first direction R. The internal space of the housing portion 201 defines a mixing space 20a and a diversion channel 201a. A water outlet 201b is formed on the side wall of the housing portion 201. Among them, the mixing space 20a is located on one side of the diversion channel 201a along the first direction R.

[0071] It can be understood that in the nozzle unit 200, the housing 201 is provided with a water outlet 201b, and the mixing space 20a communicated with the water outlet 201b is arranged inside the housing 201, and the diversion channel 201a communicated with the mixing space 20a is also arranged inside the housing 201 along the first direction R. That is to say, the chambers inside the housing 201 respectively form the mixing space 20a and the diversion channel 201a. Such a design structure is compact, which is not only beneficial to the arrangement of the diversion channel 201a and the mixing space 20a, but also beneficial to the connection of the first waterway 40A and the second waterway 50A to the nozzle unit 200.

[0072] In some embodiments, please refer to Figure 4 , the nozzle unit 200 includes a first joint pipe 204 and a second joint pipe 205. The first joint pipe 204 and the second joint pipe 205 are arranged at intervals along the first direction R and are both connected to the housing 201. The space inside the first joint pipe 204 forms a part of the first waterway 40A, and the space inside the second joint pipe 205 forms a part of the second waterway 50A.

[0073] That is, the first waterway 40A extends into the nozzle unit 200 through the first joint pipe 204, and the second waterway 50A extends into the nozzle unit 200 through the second joint pipe 205. The first joint pipe 204 and the second joint pipe 205 are arranged in parallel, and there is a certain distance between them. The orientation of the first direction R is not limited (for example, perpendicular to the radial direction of the door seal ring 60). In this way, space is reserved for the installation of the nozzle unit 200.

[0074] In some embodiments, please refer to Figure 5 , the housing 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 housing 201 bends towards the rear side of the laundry treatment chamber, and the first end wall 2011 is inclined towards the lower part of the rear side of the laundry treatment chamber.

[0075] In this embodiment, the housing 201 not only forms a chamber for fluid movement, but also plays a guiding role in the movement of the fluid. The bending feature of the housing 201 can realize the transition between the transitions of the fluid in different flow directions. For example, in the embodiment where the first joint pipe 204 and the second joint pipe 205 both extend along the radial direction of the door seal ring 60, the bending feature of the housing 201 makes the flow direction of the fluid transition from the radial direction when entering the housing 201 to the inclined downward direction towards the rear side of the laundry treatment chamber when spraying.

[0076] In some embodiments, please refer to Figure 6, the housing part 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 housing part 201, the second side wall 2014 is located on the concave side of the bending direction of the housing part 201, and the opposite ends of the first side wall 2013 and the second side wall 2014 along the first direction R are respectively connected by the transition connecting wall 2015.

[0077] In some embodiments, in the direction from the second end wall 2012 to the first end wall 2011, the first side wall 2013 is arc-shaped and extends obliquely downward to achieve the guiding effect on the fluid.

[0078] In some embodiments, please refer to Figure 4 , the transition connecting wall 2015 is arc-shaped and bent from one end of the first side wall 2013 to one end of the second side wall 2014.

[0079] In some embodiments, please refer to Figure 7 and Figure 8 , the nozzle unit 200 includes a nozzle part 202. The nozzle part 202 is arranged inside the mixing space 20a. The outlet of the nozzle part 202 constitutes the outlet of the second water path 50A, and the outlet of the nozzle part 202 faces the water outlet 201b.

[0080] The fluid of the second water path 50A is ejected from the outlet of the nozzle part 202, impacts the detergent mixed solution of the first water path 40A in the mixing space 20a, and directly enters the laundry treatment cavity through the water outlet 201b. The form of the water outlet end of the second water path 50A has less attenuation in the mixing space 20a, approximating the form when ejected from the outlet of the nozzle part 202, driving the fluid in the mixing space 20a to be ejected.

[0081] Exemplarily, please refer to Figure 5 , the nozzle part 202 is formed with a reduced diameter section 22. The turbulent flow structure 21 is arranged in the second joint pipe 205 and is located upstream of the reduced diameter section 22. After the fluid of the second water path 50A passes through the turbulent flow structure 21 and the reduced diameter section 22 and is ejected from the outlet of the nozzle part 202, its speed is increased and it has a circumferential speed component. In this way, the water outlet form of the water outlet 201b can present a more visually effective conical shape, and the ejected mixed fluid is more dispersed, directly sprayed on the laundry to be processed, improving the washing effect.

[0082] The nozzle unit 200 in the embodiments of the present application can be an integral component, that is to say, the housing part 201, the nozzle part 202, the first joint pipe 204 and the second joint pipe 205 are integrally formed, for example, processed by injection molding and other processes. Of course, the nozzle unit 200 can also be a split component and assembled after processing.

[0083] In some embodiments, please refer to Figure 1, the nozzle unit 200 is radially disposed through the door seal ring 60, and the water outlet 201b is located radially inside the door seal ring 60. That is, the door seal ring 60 provides installation support for the nozzle unit 200.
