DETAILED DESCRIPTION

[0034] 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.

[0035] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They 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 devices or elements referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood 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 understood as indicating or implying relative importance.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] See also Figures 1 to 10 The embodiment of the present application provides a detergent dispensing device 100, comprising a detergent supply assembly 30, a liquid outlet waterway, a first waterway 40A, and a second waterway 50A. The dashed arrows in the drawings indicate the direction of fluid flow.

[0040] An embodiment of the present application further provides a clothing processing device, comprising a clothing processing chamber and the detergent dispensing device 100 in any embodiment of the present application, wherein the water outlet end of the liquid outlet waterway is connected to the clothing processing chamber.

[0041] The clothing processing chamber is used to accommodate clothing to be processed. For example, in one embodiment, 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 connecting space formed by the interior of the barrel assembly 10 and the radial inner side of the door sealing ring 60 constitutes the clothing processing chamber.

[0042] The detergent supply assembly 30 has a first drain port 30 b for draining the detergent mixed solution. That is, the detergent mixed solution flows out from the first drain port 30 b.

[0043] 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.

[0044] See also Figure 2 and Figure 10 The liquid outlet waterway has an inlet and an outlet. The first waterway 40A and the second waterway 50A are used to transport fluid. The first waterway 40A connects the water source, the first drain port 30b, and the inlet of the liquid outlet waterway. The fluid in the first waterway 40A is a mixed detergent solution. It will be appreciated that the mixed detergent solution discharged from the first drain port 30b enters the first waterway 40A, whereupon the mixed detergent solution forms in the first waterway 40A and is then passed into the liquid outlet waterway.

[0045] See also Figure 3 and Figure 10Second water channel 50A connects the water source and the inlet end of the liquid outlet channel, and a portion of second water channel 50A is disposed within detergent supply assembly 30. Second water channel 50A allows fluid from the water source to flow into the liquid outlet channel, where it merges with fluid from first water channel 40A. The two fluids collide and mix in the liquid outlet channel, promoting detergent dissolution and improving the cleaning efficiency. The mixed fluid is then delivered through the outlet end of the liquid outlet channel into the laundry treatment chamber, where it comes into contact with the laundry to be treated.

[0046] 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 device further includes a circulation pump, and the water inlet end of the second water channel 50A is connected to the water outlet of the circulation pump. In other embodiments, the laundry processing device further includes a water inlet valve 90, and the water inlet end of the second water channel 50A is connected to the first outlet 90a of the water inlet valve 90.

[0047] It should be noted that the liquid outlet waterway refers to the flow path from the point where the first waterway 40A and the second waterway 50A mix to the point where the mixed fluid exits the liquid outlet waterway. The inlet end of the liquid outlet waterway refers to the point where the fluid in the first waterway 40A leaves the first waterway 40A and enters the liquid outlet waterway, and the point where the fluid in the second waterway 50A leaves the second waterway 50A and enters the liquid outlet waterway. The outlet end of the liquid outlet waterway refers to the point where the fluid in the liquid outlet waterway exits the liquid outlet waterway.

[0048] In the embodiments of the present application, the first water channel 40A and the second water channel 50A merely refer to the flow paths of the fluid and are not limited to pipe structures. At least a portion of the second water channel 50A is disposed within the detergent supply assembly 30. This means that there is at least one path for fluid circulation within the detergent supply assembly 30, and the fluid in the second water channel 50A flows through the detergent supply assembly 30. It should be noted that the path of the second water channel 50A flowing through the detergent supply assembly 30 is not interconnected with the detergent flow path within the detergent supply assembly 30. This improves the reuse of the detergent supply assembly 30, reduces the space occupied by the detergent dispensing device 100, and facilitates the placement of the detergent dispensing device 100 within the laundry processing apparatus.

[0049] For example, in one embodiment, the detergent supply assembly 30 includes a detergent box and a dispenser box. The dispenser box is pullable inside the detergent box, and the user can put in detergent by pulling out the dispenser box. The second water channel 50A can be partially set in the detergent box.

[0050] Illustratively, in one embodiment, a portion of the first water channel 40A is disposed in the detergent supply assembly 30, and a detergent delivery chamber 30A is provided in the detergent supply assembly 30 (for example, formed in a dispenser box). The fluid in the first water channel 40A flows through the detergent delivery chamber 30A, mixes with the detergent, and forms a detergent mixed solution, which is discharged through the first drain port 30b. Therefore, in this embodiment, both the first water channel 40A and the second water channel 50A pass through the detergent supply assembly 30, resulting in a compact structure and further improving space utilization.

[0051] A portion of the second water channel 50A is disposed in the detergent supply assembly 30 , including but not limited to the following two types.

[0052] In the first embodiment, the detergent dispensing device 100 includes a first tube body, one end of which is connected to a water source, and the other end is used to guide the fluid to an outlet waterway. The space in the first tube body defines at least a portion of a second waterway, and the first tube body passes through the detergent supply assembly 30.

[0053] It is understood that the first tube body can be a single tube or a tube formed by splicing multiple tube segments, connecting the water source to the liquid outlet waterway, allowing fluid from the water source to enter the liquid outlet waterway. The first tube body passes through the detergent supply assembly 30. It can be seen that the first tube body is independent of the detergent supply assembly 30 and can be detachably assembled to the detergent supply assembly 30. In this way, the detergent dispensing device 100 has a simple structure and high reliability. The first waterway 40A also has fewer components, which can reduce fluid leakage at the component connections.

[0054] In the second embodiment, please refer to Figure 2 and Figure 3 The detergent dispensing device 100 includes a first pipe section 501 and a second pipe section 502. The detergent supply assembly 30 has a water passage (not shown). The first pipe section 501 connects to a water source and the inlet of the water passage, while the second pipe section 502 connects to the outlet of the water passage and the water inlet of the liquid outlet waterway. The space within the first pipe section 501, the water passage, and the space within the second pipe section 502 collectively define at least a portion of the second waterway 50A.

[0055] It is understood that the fluid from the water source enters the nozzle unit 200 through the first pipe section 501, the water passage, and the second pipe section 502. The water passage is formed within the detergent supply assembly 30, with its ends connected to the first pipe section 501 and the second pipe section 502, respectively. It can be seen that the water passage and the detergent supply assembly 30 are integrated into one body. This improves the integration of the detergent supply assembly 30, facilitating the manufacture of the detergent supply assembly 30 and the assembly of the detergent dispensing device 100.

[0056] For some examples, see Figure 9 and Figure 10 The detergent dispensing device 100 further includes a turbulent flow structure 21 disposed in the second water channel 50A, for providing a circumferential velocity component to the fluid in the second water channel 50A.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] For some examples, see Figure 9 and Figure 10 A diameter-reducing section 22 is provided 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.

[0063] For example, in some embodiments, the end of the reduced diameter section 22 forms the outlet 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, 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.

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

[0066] 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.

[0067] For some examples, see Figure 5 、 Figure 6 and Figure 7 The detergent supply assembly 30 includes a detergent delivery chamber 30A and a mixing chamber 30B. A first water channel 40A flows through the detergent mixing chamber 30B and a first drain port 30b. The mixing chamber 30B is used to receive the detergent mixed solution discharged from the detergent delivery chamber 30A. The first drain port 30b is provided on the wall of the mixing chamber 30B.

[0068] The detergent mixed solution discharged from the detergent dispensing chamber 30A can directly flow into the mixing chamber 30B and be discharged through the first drain port 30b on the wall of the mixing chamber 30B. This eliminates the need for additional drainage piping and allows the structure of the detergent supply assembly 30 to be more compact. For example, the mixing chamber 30B is located below the detergent dispensing chamber 30A, and the detergent mixed solution flows downward into the mixing chamber 30B due to gravity.

[0069] For some examples, see Figure 4 The detergent supply assembly 30 includes a filter structure 302, which is arranged on the top side of the mixing chamber 30B. The filter structure 302 has a plurality of filter holes, which are connected to the mixing chamber 30B and are used to filter the detergent mixed solution discharged from the detergent delivery chamber 30A.

[0070] It should be noted that the detergent mixed solution discharged from the detergent delivery chamber 30A will flow onto the filter structure 302, enter the mixing chamber 30B through the filter hole, and then be discharged from the first drain port 30b at the mixing chamber 30B, that is, the filter hole is used to filter the detergent mixed solution discharged from the detergent delivery chamber 30A.

[0071] It is understood that when the detergent introduced into the detergent dispensing chamber 30A is in a powdered form, such as washing powder, it may clump due to factors such as a humid storage environment or insufficient dissolution during dispensing. This may result in lumps of washing powder remaining in the mixed detergent solution discharged from the detergent dispensing chamber 30A. The filtering effect of the filter structure 302 can effectively prevent the washing powder lumps from entering the mixing chamber 30B, thereby minimizing blockage of downstream pipes. Furthermore, the mixed detergent solution discharged from the detergent dispensing chamber 30A can flush out the washing powder lumps blocked by the filter structure 302, thereby promoting dissolution.

[0072] For some examples, see Figure 5 、 Figure 6 and Figure 7 The detergent supply assembly 30 also has an overflow chamber 30C and a second drain port 30a. The overflow chamber 30C is used to receive the detergent mixed solution overflowing from the mixing chamber 30B. The second drain port 30a is used to discharge the detergent mixed solution in the overflow chamber 30C out of the detergent dispensing device 100.

[0073] It is understood that when the water level in mixing chamber 30B is below the overflow level, the fluid in mixing chamber 30B is discharged through first drain port 30b. When the water level in mixing chamber 30B is above the overflow level, the excess fluid overflows into overflow chamber 30C and is discharged through second drain port 30a. Therefore, overflow chamber 30C and second drain port 30a serve as safety protection.

[0074] Exemplarily, the clothing processing device also includes a water inlet pipe 70, which is connected to the second drain outlet 30a and is used to guide the fluid discharged from the second drain outlet 30a into the clothing processing chamber. Therefore, when the mixing chamber 30B overflows, the second drain outlet 30a can also serve as an auxiliary water inlet.

[0075] For some examples, see Figure 7 The detergent supply assembly 30 includes a partition structure 301. The overflow chamber 30C and the mixing chamber 30B are located on opposite sides of the partition structure 301. That is, the partition structure 301 separates the overflow chamber 30C and the mixing chamber 30B. One end of the filter structure 302 extends above the partition structure 301. The filter structure 302 is arranged to be inclined downward from away from the overflow chamber 30C to closer to the overflow chamber 30C.

[0076] In this embodiment, when the flow rate out of detergent dispensing chamber 30A is high, the detergent mixture that is unable to flow through the filter holes can flow along the upper surface of filter structure 302 into overflow chamber 30C, providing a safety protection. Furthermore, detergent clumps intercepted by filter structure 302 can flow along the upper surface of filter structure 302 into overflow chamber 30C, thereby minimizing the risk of detergent clumps clogging the filter holes of filter structure 302. It should be noted that due to the large size of second drain outlet 30a, the risk of clogging is minimal.

[0077] For example, in some embodiments, the size of the first drain opening 30b is smaller than the size of the second drain opening 30a.

[0078] For some examples, see Figure 2 and 10The detergent dispensing device 100 includes a nozzle unit 200, the liquid outlet water channel is located in the nozzle unit 200, the water outlet end of the first water channel 40A and the water outlet end of the second water channel 50A are located in the nozzle unit 200, and the water outlet end of one of the first water channel 40A or the second water channel 50A is provided with a guide channel 201a, which is used to guide the fluid toward the water outlet end of the other.

[0079] In the nozzle unit 200, the guide channel 201a makes the water outlet ends of the first water channel 40A and the second water channel 50A close to each other. After being sprayed out, the fluid in the first water channel 40A is mixed with the fluid sprayed out of the second water channel 50A. In this way, the impact force of the fluid spraying is utilized to enhance the mixing effect of the two fluids, thereby promoting the dissolution of the detergent and further improving the cleaning ratio.

[0080] In some embodiments, along the direction of fluid movement, the flow cross-sectional area of the flow guiding channel 201a gradually increases.

[0081] It should be noted that the flow cross-section of the diversion channel 201a is largest at the end of the flow direction. Under the guidance of the diversion channel 201a, the fluid therein tends to concentrate toward one end near the outlet waterway, so that it is impacted as much as possible by the fluid ejected from the outlet end of the other waterway and fully mixed with it.

[0082] In some embodiments, the flow rate at the water outlet of the first water channel 40A is lower than the flow rate at the water outlet of the second water channel 50A, and the diversion channel 201 a forms the water outlet of the first water channel 40A.

[0083] That is, the guide channel 201a guides the fluid with a slower flow rate to the fluid with a faster flow rate, thereby utilizing the impact force of the water flowing out of the second water channel 50A with a faster flow rate to fully mix it with the fluid in the first water channel 40A and enhance the foaming effect of the detergent.

[0084] As an optional embodiment, in an embodiment where the flow velocity at the outlet of the first water channel 40A is less than that at the outlet of the second water channel 50A, the cross-sectional area of the flow path 201a gradually increases along the direction of fluid movement. This reduces the velocity of the fluid in the first water channel 40A within the flow path 201a, increasing the difference in flow velocity between the outlets of the first water channel 40A and the second water channel 50A. This results in a more effective impact of the fluid in the second water channel 50A on the fluid in the first water channel 40A, resulting in a better mixing effect.

[0085] In some embodiments, the nozzle unit 200 includes a first connecting pipe 204, a second connecting pipe 205 and a shell 201, the shell 201 has a water outlet 201b, the first connecting pipe 204 and the second connecting pipe 205 are respectively connected to the shell 201, the first water channel 40A flows through the first connecting pipe 204, the second water channel 50A flows through the second connecting pipe 205, and the fluids in the first water channel 40A and the second water channel 50A converge in the shell 201 and are sprayed out through the water outlet 201b.

[0086] It should be noted that the liquid outlet water channel is located in the nozzle unit 200, and the fluid discharged from the water outlet end of the liquid outlet water channel enters the clothing processing chamber through the water spray port 201b, that is, the liquid outlet water channel is formed inside the shell 201. After the two fluids in the shell 201 are mixed, they leave the liquid outlet water channel and are sprayed out from the water spray port 201b.

[0087] The first joint pipe 204 can be used as an installation structure for connecting the nozzle unit 200 with the first water channel 40A, and the second joint pipe 205 can be used as an installation structure for connecting the nozzle unit 200 with the second water channel 50A. The structure of the nozzle unit 200 is conducive to fluid mixing, easy to install, and relatively compact.

[0088] For some examples, see Figure 1 and Figure 8 The first and second joint tubes 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 mounted on the door seal 60, facilitating the fluid ejected from the water outlet 201b to be sprayed onto the clothing to be treated.

[0089] For some examples, see Figure 9 The water outlet 201b is used to spray water obliquely downward toward the rear side of the clothing treatment chamber. In other words, the water outlet 201b sprays water rearward and downward, and the fluid at the water outlet 201b has both a downward velocity component and a velocity component along the axial rear side of the clothing treatment chamber. That is, the centerline n of the water outlet 201b forms an acute angle φ with the reference plane m. The reference plane m is perpendicular to the axis of the clothing treatment chamber. Spraying the detergent mixture onto the clothing to be treated can increase the contact area between the detergent and the clothing to be treated, which is beneficial to improving the efficiency of the clothing treatment device in treating clothing.

[0090] The value of the acute angle φ is not limited. For example, the acute angle φ formed by the centerline n of the water jet 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 jet 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.

[0091] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0092] 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.
