However, the detergent is often not fully dissolved and mixed unevenly with the water flow, resulting in insufficient utilization of the detergent, poor cleaning effect, and affecting the user experience. In addition, some related technologies use clean water to dilute the solution at the drain outlet of the detergent box, and then flow it along the pipeline to the clothing treatment chamber, but the cleaning effect is still poor.

[0022] The detergent dispensing device and clothing treatment equipment provided by the embodiment of the present application have a water outlet cross-sectional area at the water outlet end of the first water channel that is larger than the water outlet cross-sectional area at the water outlet end of the second water channel, so that when the detergent mixed solution enters the mixing space from the first water channel, the detergent components per unit volume have a larger contact area with the fluid in the mixing space, which is conducive to more uniform mixing and more complete dissolution of the detergent components.

[0033] 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.

[0034] 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" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] The present invention provides a detergent dispensing device 100. Figure 2 , includes a detergent supply assembly, a spray head unit 200, and a first water channel 40A and a second water channel 50A for conveying fluid.

[0039] The present application also provides a clothes processing device. Figure 1 The clothing processing device includes a clothing processing chamber and a detergent dispensing device 100 in any embodiment of the present application.

[0040] 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.

[0041] For example, see Figure 1 The clothing processing device further includes a barrel assembly 10 and a door sealing ring 60 arranged on the front side of the barrel assembly 10. The connecting space formed by the interior of the barrel assembly 10 and the radial inner side of the door sealing ring 60 forms a clothing processing chamber.

[0042] See also Figure 7 In the detergent dispensing device 100, the detergent supply assembly has a first drain port for discharging the detergent mixed solution. The nozzle unit 200 has a mixing space 20a, and a water outlet 201b is formed on the side wall of the mixing space 20a. That is, the water outlet 201b is located on the wall of the mixing space 20a and is connected to the mixing space 20a.

[0043] The first water channel 40A connects the water source, the first drain port, and the mixing space 20a, while the second water channel 50A connects the water source and the mixing space 20a. Fluids in both the first water channel 40A and the second water channel 50A flow into the mixing space 20a, while the water outlet 201b is used to discharge the fluid within the mixing space 20a. It will be understood that when the detergent mixed solution discharged from the first drain port enters the first water channel 40A, the fluid flowing into the mixing space 20a from the first water channel 40A is the detergent mixed solution, while the fluid flowing into the mixing space 20a from the second water channel 50A is related to the water source connected to the second water channel 50A.

[0044] The detergent mixed solution mentioned in this specification is for convenience only and refers to a mixed solution containing dissolved detergent. The concentration by mass percentage 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.

[0045] Exemplarily, in one embodiment, the detergent supply assembly includes a detergent delivery chamber, through which a user can add detergent. The detergent delivery chamber is located on the first water channel 40A. The fluid of the water source passes through the first water channel 40A into the detergent delivery chamber, is preliminarily mixed with the detergent to form a detergent mixed solution, and flows toward the first drain outlet.

[0046] The fluid in the second water channel 50A is not limited and can be tap water or a fluid containing detergent components. For example, in some embodiments, the clothing processing device further includes a circulation pump, and the water inlet end of the second water channel 50A is connected to the circulation pump. In other embodiments, such as Figure 2 As shown, the laundry processing device further includes a water inlet valve 90, and the water inlet end of the second water path 50A is connected to the first outlet 90a of the water inlet valve 90. The dashed lines with arrows in the drawings of this specification indicate the flow direction of the fluid.

[0047] It can be understood that the fluids in the first water channel 40A and the second water channel 50A converge in the mixing space 20a of the nozzle unit 200, and the two fluids impact and mix with each other, which can promote the dissolution of detergent components, make the detergent components in the detergent mixed solution more uniform, and improve the washing ratio of the clothing processing equipment.

[0048] See also Figure 7 The water outlet cross-sectional area (referenced at position y) of the outlet end of the first water channel 40A is larger than the water outlet cross-sectional area (referenced at position x) of the outlet end of the second water channel 50A, and the water outlet cross-sectional area of ​​the outlet end of the first water channel 40A is smaller than the water outlet cross-sectional area (referenced at position z) of the outlet port 201b. In other words, the water outlet cross-sectional area F1 of the outlet port 201b, the water outlet cross-sectional area F2 of the outlet end of the first water channel 40A, and the water outlet cross-sectional area F3 of the outlet end of the second water channel 50A decrease in order, i.e., F1>F2>F3.

[0049] The water outlet cross-section of the water outlet end of the first water channel 40A is the cross-section at the intersection where the fluid leaves the first water channel 40A and enters the mixing space 20a. Similarly, the water outlet cross-section of the water outlet end of the second water channel 50A is the cross-section at the intersection where the fluid leaves the second water channel 50A and enters the mixing space 20a. The water outlet cross-section of the water outlet 201b is the cross-section at the intersection where the fluid leaves the mixing space 20a and enters the external environment (e.g., the laundry processing chamber).

[0050] 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.

[0051] The water outlet cross-section of the water outlet end of the first water channel 40A and the water outlet cross-section of the water outlet end of the second water channel 50A are both smaller than the water outlet cross-section area of ​​the water outlet 201b, so that the water outlet 201b can discharge the fluid in the mixing space 20a as promptly as possible, so as to reduce the fluid congestion in the mixing space 20a and reduce the probability of the fluid in the mixing space 20a flowing back to the first water channel 40A and the second water channel 50A, which is beneficial to improving the reliability of the detergent dispensing device 100.

[0052] It can be seen that the detergent dispensing device 100 provided in the embodiment of the present application can promote the dissolution of detergent, improve the cleaning ratio of the clothing processing equipment, and has good reliability.

[0053] For some examples, see Figure 4 and Figure 8 The outlet end of the second water channel 50A discharges water toward the water outlet 201b. In this way, the fluid discharged from the outlet end of the second water channel 50A can drive the fluid in the mixing space 20a to be ejected through the water outlet 201b. Furthermore, the water discharge form of the water outlet 201b is similar to the water discharge form of the outlet end of the second water channel 50A, eliminating the need for an additional drainage pipe at the water outlet 201b.

[0054] For example, the water outlet 201b discharges the fluid in the mixing space 20a into the laundry processing chamber of the laundry processing device. The aforementioned discharge into the laundry processing chamber means that the fluid ejected from the water outlet 201b does not need to be guided by other structures, but instead is directly sprayed into the laundry processing chamber due to inertia, thereby spraying the clothes in the laundry processing chamber and improving the cleaning effect.

[0055] For some examples, see Figure 5 A diameter-reducing section 22 is formed at the end of the second water channel 50A so as to increase the flow rate at the water outlet end of the second water channel 50A.

[0056] For example, in some embodiments, the end of the reduced diameter section 22 forms the outlet of the second waterway 50A. In other words, the fluid in the second waterway 50A 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 second waterway 50A, and the fluid in the second waterway 50A is ejected from the end of the constant diameter section or the expanded diameter section.

[0057] 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.

[0058] 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 at the outlet end of the first water channel 40A, thereby achieving a better mixing effect.

[0059] At the same time, the reduced diameter section 22 makes the water outlet end of the second water channel 50A have a larger injection speed, which can generate obvious negative pressure in a relatively large area around it, so that the fluid at the water outlet end of the first water channel 40A is sucked in under the action of the negative pressure and mixed with the fluid in the second water channel 50A, thereby improving the mixing and foaming effects.

[0060] For some examples, see Figure 5 and Figure 8 The clothes processing apparatus includes a turbulent flow structure 21 , which is provided in the second water channel 50A and is used to provide a circumferential velocity component to the fluid in the second water channel 50A.

[0061] The above-mentioned circumferential velocity component refers to the fluid in the second water channel 50A after passing through the turbulent structure 21, whose velocity direction in the circumferential direction of the second water channel 50A is not zero, and the circumferential direction of the second water channel 50A is perpendicular to the extension direction of the second water channel 50A.

[0062] 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 outlet end of the second waterway 50A, the fluid is facilitated to diffuse in a conical shape, with a wider radiation range and better visual effect.

[0063] Exemplarily, the turbulent flow structure 21 includes one or more spiral blades, which divide at least a partial length of the second water channel 50A where the spiral blades are located into a plurality of sub-flow channels.

[0064] 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.

[0065] 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.

[0066] For some examples, see Figure 8A guide channel 201a is formed at the end of the first water channel 40A. The guide channel 201a is used to guide the fluid in the first water channel 40A toward the outlet of the second water channel 50A. In other words, the outlet of the first water channel 40A and the outlet of the second water channel 50A are close to each other. Under the backflow effect of the guide channel 201a, the detergent mixed solution in the first water channel 40A is discharged toward the outlet of the second water channel 50A. This allows the fluid discharged from the second water channel 50A to directly impact the fluid from the first water channel 40A in the mixing space 20a, promoting mixing and dissolution.

[0067] See also Figure 7 , along the flow direction of the fluid, the flow cross-sectional area of ​​the guide channel 201a gradually increases.

[0068] It should be noted that the flow cross-section of the diversion channel 201a is largest at the end near one end of the mixing space 20a. This cross-section, also known as the outlet cross-section of the first waterway, has an area of ​​F2. Guided by the diversion channel 201a, the fluid within it tends to concentrate toward the end near the mixing space 20a, filling the mixing space 20a as much as possible and thoroughly mixing with the fluid at the outlet end of the other waterway.

[0069] For some examples, see Figure 5 and Figure 7 The nozzle unit 200 includes a shell 201 and a nozzle 202. The mixing space 20a is located in the shell 201. The water outlet 201b is arranged on the cavity wall of the shell 201. The nozzle 202 is arranged in the mixing space 20a. The nozzle 202 is arranged at the end of the second water channel 50A, and is used to increase the flow rate of the water outlet end of the second water channel and spray the fluid of the second water channel toward the water outlet.

[0070] As an optional embodiment, a reduced diameter section 22 may be formed inside the mouth 202 .

[0071] It can be understood that the mouth 202 is arranged in the shell 201, and the mouth 202 extends into the mixing space 20a. The fluid in the second waterway 50A enters the mixing space 20a through the mouth 202, that is, the water outlet cross-section of the water outlet end of the second waterway 50A is at a certain distance from the wall of the mixing space 20a, so that the mouth 202 can suck the fluid from the first waterway 40A when spraying the fluid, so as to achieve further mixing of the fluid in the first waterway 40A and the fluid in the second waterway 50A.

[0072] The above-mentioned suction of the fluid from the first water channel 40A means that when the nozzle 202 sprays the fluid, 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 nozzle 202 to improve the mixing effect of the fluid in the first water channel 40A and the fluid in the second water channel 50A.

[0073] As an optional embodiment, the mouth 202 discharges water toward the water outlet 201b. In this way, the distance from the fluid in the second water channel 50A leaving the second water channel 50A to being sprayed out from the water outlet 201b is shorter, which can reduce the escape of the water form at the water outlet end of the second water channel 50A and make it easier for the air in the external environment to be sucked into the mixing space 20a, thereby improving the foaming effect of the detergent.

[0074] For some examples, see Figure 4 The nozzle unit 200 also includes a first joint pipe 204 and a second joint pipe 205, which are respectively connected to the shell 201 and are arranged at intervals along the first direction R. The first water channel 40A flows through the first joint pipe 204, and the second water channel 50A flows through the second joint pipe 205.

[0075] First connector pipe 204 serves as a mounting structure for connecting spray head unit 200 to first waterway 40A, while second connector pipe 205 serves as a mounting structure for connecting spray head unit 200 to second waterway 50A. For example, first waterway 40A and second waterway 50A each comprise one or more sections of conduit, with some sections connected to first connector pipe 204 and others to second connector pipe 205, thereby allowing fluid to flow into spray head unit 200.

[0076] The first joint pipe 204 and the second joint pipe 205 are arranged at intervals along the first direction R, that is, the first joint pipe 204 and the second joint pipe 205 are arranged side by side, and there is a certain distance between the two. The direction of the first direction R is not limited (for example, perpendicular to the radial direction of the door sealing ring 60). In this way, space is reserved for the installation of the nozzle unit 200.

[0077] For example, in some embodiments, please refer to Figure 1 The door seal 60 has a first mounting opening (not shown) and a second mounting opening (not shown). The first joint pipe 204 is inserted through the first mounting opening, and the second joint pipe 205 is inserted through the second mounting opening. Thus, the spray head unit 200 is connected to the door seal 60 via the first joint pipe 204 and the second joint pipe 205, facilitating installation. During assembly, the spray head unit 200 can be first secured, and then the first joint pipe 204 and the second joint pipe 205 can be connected to the first water channel 40A and the second water channel 50A, respectively.

[0078] For some examples, see Figure 6The 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 and lower part of the clothing processing chamber of the clothing processing device.

[0079] 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.

[0080] In some embodiments of the laundry processing apparatus, the water outlet 201b is used to spray water obliquely downward toward the rear side of the laundry processing chamber. Figure 3 and Figure 5 Water outlet 201b sprays water downward and rearward. The fluid at 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 centerline n of outlet 201b forms an acute angle φ with the reference plane m, which is perpendicular to the axis of the laundry treatment chamber.

[0081] In this way, the detergent mixed solution is applied to the clothes to be treated in a spraying manner, which can increase the contact area between the detergent and the clothes to be treated, which is beneficial to improving the efficiency of the clothes treating device in treating clothes.

[0082] 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.

[0083] The nozzle unit 200 in the embodiment of the present application can be a one-piece component, that is, the shell 201, nozzle 202, first connector pipe 204, and second connector pipe 205 are integrally formed, for example, by injection molding. Of course, the nozzle unit 200 can also be a split component that can be assembled after processing.

[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.
