[0012] In some embodiments, the detergent supply assembly has a spacer structure;

[0013] The overflow chamber and the mixing chamber are respectively located on opposite sides of the partition structure, and the partition structure extends to the top of the partition structure; or, the partition structure extends to the surface of the partition structure facing the mixing chamber, and the top surface of the partition structure is not lower than the top edge of the partition structure.

[0036] 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.

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.

[0038] 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.

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

[0041] The present invention provides a detergent dispensing device 100. Figure 7 The detergent dispensing device 100 includes a detergent supply assembly 30 , which includes a first drain port 30 b , a detergent dispensing cavity 30A, a partition structure 302 , and a first bottom wall portion 303 .

[0042] The present invention also provides a laundry processing device, comprising a laundry processing chamber and a detergent dispensing device 100 in any embodiment of the present invention. The laundry processing chamber is used to accommodate laundry to be processed, and the detergent dispensing device 100 is used to dispense a detergent mixed solution into the laundry processing chamber.

[0043] The form of the clothing processing device is not limited, and it can be a drum washing machine, a pulsator washing machine, a drum washer-dryer, a pulsator washer-dryer, etc. This manual takes a drum washing machine as an example.

[0044] For example, see Figure 1 The clothing processing device includes a barrel assembly 10 and a door sealing ring 60 arranged on the front side of the barrel assembly 10. The connecting space composed of the interior of the barrel assembly 10 and the radial inner side of the door sealing ring 60 constitutes a clothing processing chamber (not shown).

[0045] See also Figure 4 and Figure 7The partition structure 302 is disposed above the first bottom wall portion 303. The space between the first bottom wall portion 303 defines a mixing chamber 30B. The first drain port 30b communicates with the mixing chamber 30B. In other words, the top surface of the first bottom wall portion 303 forms the bottom wall of the mixing chamber 30B, while the bottom surface of the partition structure 302 forms the top wall of the mixing chamber 30B. The partition structure 302 is plate-shaped, but is not limited to being straight or curved.

[0046] The detergent mixed solution discharged from the detergent delivery chamber 30A flows through the partition structure 302 and enters the mixing chamber 30B. The fluid in the mixing chamber 30B is discharged through the first drain port 30b and finally enters the clothing processing chamber of the clothing processing device.

[0047] 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 require the detergent to be completely dissolved. The detergent can be in any form and can be powdered laundry detergent, liquid laundry detergent, or softener. The detergent in the detergent dispensing chamber 30A mixes with the fluid to form the detergent mixed solution. Furthermore, dashed arrows in the figures of this specification indicate the direction of fluid flow.

[0048] The manner in which the detergent mixed solution flows through the partition structure 302 and enters the mixing chamber 30B includes but is not limited to: the detergent mixed solution flows down from the edge of the partition structure 302, or the partition structure 302 has a through hole connected to the mixing chamber 30B, and the shape and number of the through holes are not limited, and the detergent mixed solution flows into the mixing chamber 30B from the above-mentioned through holes.

[0049] In the detergent dispensing device provided in the embodiment of the present application, since the partition structure 302 is provided, on the one hand, the flow path of the detergent mixed solution from its formation in the detergent dispensing chamber 30A to its discharge from the first drain port 30b is longer, and the mixing effect between the detergent and the fluid is better; on the other hand, when the detergent is washing powder, it is easy to form washing powder lumps due to factors such as insufficient dissolution or moisture. When the detergent mixed solution flows through the partition structure 302, due to the different properties of solid and liquid, at least part of the washing powder lumps remain on the partition structure 302, thereby reducing the probability of downstream structures being blocked by washing powder lumps and improving the reliability of the detergent dispensing device.

[0050] In some embodiments, the partition structure 302 has a plurality of through holes, which are connected to the mixing chamber 30B. The through holes are used to filter the detergent mixed solution discharged from the detergent delivery chamber 30A and discharge the filtered detergent mixed solution into the mixing chamber 30B.

[0051] After the detergent mixture in detergent dispensing chamber 30A is discharged, it is filtered by gravity through partition structure 302 before entering mixing chamber 30B below. It then flows out of detergent supply assembly 30 through first drain port 30b. During this process, partition structure 302 filters the detergent mixture. On the one hand, the multiple holes in partition structure 302 promote mixing of the detergent mixture with air as it passes through partition structure 302, thereby enhancing the foaming effect of the detergent. On the other hand, if the detergent is washing powder, partition structure 302 can intercept any clumps of washing powder that are larger than the holes, reducing the chance of them clogging first drain port 30b and downstream structures after entering mixing chamber 30B, further improving the reliability of detergent dispensing device 100.

[0052] For example, the diameter of the via holes ranges from 2 mm to 3.5 mm (millimeter), including but not limited to 2 mm, 2.5 mm, 3 mm, and 3.5 mm. This effectively intercepts lumps of detergent powder and minimizes the flow rate of the detergent mixed solution into the mixing chamber 30B. The diameters of the via holes can be the same or different.

[0053] It should be noted that the form of the partition structure 302 is not limited. For example, the partition structure 302 can be a straight plate (eg Figure 4 as shown), or in a groove shape, etc.

[0054] For some examples, see Figure 7 The first end of the partition structure 302 along the first direction is used to receive the detergent mixed solution discharged from the detergent delivery chamber 30A. The partition structure 302 extends downwardly and obliquely in the first direction away from the first end. The first direction is the inclination direction of the partition structure 302.

[0055] On the inclined partition structure 302, the washing powder blocks have a tendency to displace along the first direction. All or part of the washing powder blocks intercepted on the partition structure 302 can be concentrated along the first direction away from the first end, which can reduce the number of through-holes blocked by the washing powder blocks, so that the flow rate of the detergent mixed solution entering the mixing chamber 30B is less affected.

[0056] In addition, the detergent mixed solution discharged from the detergent delivery chamber 30A also flows from the first end of the partition structure 302 along the first direction on the partition structure 302, which can flush the detergent blocks remaining on the partition structure 302 and promote the dissolution of the detergent, so that its size becomes small enough to easily pass through the through hole and enter the mixing chamber 30B.

[0057] For some examples, see Figure 7The bottom wall 304 of the detergent delivery chamber 30A is arranged above the partition structure 302, and the bottom wall 304 of the detergent delivery chamber 30A is arranged at an angle to guide the detergent mixed solution discharged from the detergent delivery chamber 30A to the first end of the partition structure 302.

[0058] That is, after the detergent mixed solution in the detergent dispensing chamber 30A is discharged, it flows down along the second bottom wall portion 304 and flows downward in the first direction from the first end of the partition structure 302. In this way, there is no need to provide an additional drainage pipeline for the detergent dispensing chamber 30A. Instead, the detergent mixed solution is guided to the partition structure 302 via the second bottom wall portion 304 within the detergent supply assembly 30, making the structure within the detergent supply assembly 30 more compact.

[0059] For example, in some embodiments, the detergent supply assembly 30 includes a detergent box 31 and a dispenser box 32. The dispenser box 32 is retractably disposed within the detergent box 31. A detergent dispensing chamber 30A is formed within the dispenser box 32, allowing the user to withdraw the dispenser box 32 and dispense the required detergent. A second bottom wall 304 and a partition structure 302 are both disposed within the detergent box 31. The dispenser box 32 is retractable and movable along the front-to-back direction of the laundry processing apparatus. The second bottom wall 304 extends downwardly and obliquely from rear to front, while the partition structure 302 extends downwardly and obliquely from front to rear and is disposed below the second bottom wall 304. This reduces the size of the detergent supply assembly 30 along the front-to-back direction, saving space while also extending the flow path of the detergent mixture within the detergent supply assembly 30, resulting in a better dissolution effect.

[0060] For some examples, see Figure 7 First drain port 30b is located at one end of first bottom wall 303 along the first direction. First bottom wall 303 extends downwardly and obliquely in the first direction toward first drain port 30b. This allows the fluid in mixing chamber 30B to spontaneously converge at first drain port 30b and be discharged from detergent supply assembly 30, eliminating the need for additional devices to power the flow of the detergent mixed solution. This arrangement also accelerates the discharge of the detergent mixed solution.

[0061] It should be noted that the first bottom wall 303 and the partition structure 302 can be inclined in the same direction, but their inclination angles can be different. For example, the partition structure 302 can be tilted more steeply than the first bottom wall 303 to facilitate the displacement of detergent lumps; or, the first bottom wall 303 can be tilted more steeply than the partition structure 302 to facilitate the rapid discharge of the detergent mixture.

[0062] For example, in some embodiments, the first drain port 30b is located at the lowest point in the mixing chamber 30B.

[0063] For some examples, see Figure 5 and Figure 6 The detergent supply assembly 30 includes 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. For example, the clothing processing equipment further includes a water inlet pipe 70. The water inlet end of the water inlet pipe 70 is connected to the second drain port 30a, and the water outlet end is connected to the barrel assembly 10 to pass the fluid in the overflow chamber 30C into the clothing processing chamber. In other words, the overflow chamber 30C and the second drain port 30a play a role in protecting the detergent dispensing device 100 and assisting water inlet.

[0064] See also Figure 7 The partition structure 302 extends downwardly and obliquely along the first direction toward the overflow chamber 30C, and is used to guide substances (e.g., laundry detergent lumps) on the top surface of the partition structure 302 that do not pass through the through-holes into the overflow chamber 30C. It is understood that the overflow chamber 30C is located on one side of the mixing chamber 30B along the first direction. Substances intercepted by the partition structure 302 that do not pass through the through-holes can enter the overflow chamber 30C along the first direction and be discharged from the detergent dispensing device 100 through the second drain port 30a. This reduces the amount of laundry detergent lumps remaining on the partition structure 302, thereby improving the reliability of the detergent dispensing device 100.

[0065] It should be noted that, since the second drain port 30 a is larger in size, there is almost no risk of blockage of the second drain port 30 a. For example, in some embodiments, the size of the first drain port 30 b is smaller than that of the second drain port 30 a.

[0066] For some examples, see Figure 5 The detergent supply assembly 30 has a partition structure 301 , and the overflow chamber 30C and the mixing chamber 30B are respectively located on opposite sides of the partition structure 301 . In this way, the internal structure of the detergent supply assembly 30 is compact.

[0067] In some embodiments, the partition structure 302 extends to the top of the spacing structure 301, which is conducive to the washing powder blocks on the partition structure 302 to pass over the spacing structure 301 and enter the overflow chamber 30C when they are displaced; in other embodiments, the partition structure 302 extends to the surface of the spacing structure 301 facing the mixing chamber 30B, and the top surface of the partition structure 302 is not lower than the top edge of the spacing structure 301, which is conducive to the washing powder blocks on the partition structure 302 to pass over the spacing structure 301 and enter the overflow chamber 30C when they are displaced.

[0068] The formation method of the first bottom wall portion 303 and the partition structure 302 is not limited. For example, in some embodiments, the first bottom wall portion 303 constitutes a portion of the bottom wall of the detergent box 31, and the partition structure 302 is disposed within the detergent box 31 and is a separate structure from the detergent box 31. In other words, the detergent box 31 and the first bottom wall portion 303 are integrally formed, which can improve the structural reliability of the detergent supply assembly 30, while the partition structure 302 is a separate component that is detachably mounted within the detergent box 31.

[0069] In other embodiments, the partition structure 302 constitutes a portion of the bottom wall of the detergent box 31, and the first bottom wall portion 303 and the detergent box 31 are separate structures, with the first bottom wall portion 303 being disposed outside the detergent box 31. In other words, the detergent box 31 and the partition structure 302 are integrally formed. For example, a through hole is provided in the bottom wall of the detergent box 31 to define the partition structure 302, while the first bottom wall portion 303 is an independent component that is detachably mounted on the outside of the detergent box 31.

[0070] For some examples, see Figure 10 and Figure 11 The detergent dispenser 100 includes a mixing space, a water outlet 201b, and a first water channel 40A and a second water channel 50A for conveying fluid. The first water channel 40A connects the water source, the first drain outlet 30b, and the mixing space, and the second water channel 50A connects the water source and the mixing space.

[0071] It can be understood that the fluid of the detergent supply assembly 30 discharged from the first drain port 30b enters the first water channel 40A, and the fluid in the first water channel 40A is a detergent mixed solution; or the detergent delivery cavity 30A is located on the first water channel 40A, and the fluid supplied by the water source enters the detergent delivery cavity 30A along the first water channel 40A, and is mixed and dissolved with the detergent to form a detergent mixed solution. The fluid in the second water channel 50A is not limited, and can be tap water or a fluid with dissolved detergent components. For example, in some embodiments, the clothing processing equipment 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 and Figure 3 As shown, the clothes treating apparatus further includes a water inlet valve 90 , and the water inlet end of the second water path 50A is connected to a first outlet 90 a of the water inlet valve 90 .

[0072] The fluids in first water channel 40A and second water channel 50A converge in the mixing space and are then sprayed through outlet 201b into the laundry processing chamber of the laundry processing apparatus. The two fluids collide and mix in the mixing space, promoting the dissolution of detergent components, making the detergent mixture more uniform, and improving the cleaning efficiency of the laundry processing apparatus.

[0073] For some examples, see Figure 8 、 Figure 11 and Figure 12 The detergent dispensing device 100 includes a nozzle unit 200, which includes a shell 201 and a nozzle 202. A mixing space is formed inside the shell 201, and a water outlet 201b is formed on the wall of the mixing space. The nozzle 202 is located inside the mixing space, and the outlet of the nozzle 202 constitutes the water outlet end of the second water channel 50A. The outlet of the nozzle 202 sprays water toward the water outlet 201b.

[0074] The mouth 202 is arranged in the shell 201, and the mouth 202 extends into the mixing space. The fluid in the second waterway 50A enters the mixing space through the mouth 202, that is, the water outlet cross-section of the water outlet end of the second waterway 50AA is at a certain distance from the wall of the mixing space, 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.

[0075] 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.

[0076] 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, thereby improving the foaming effect of the detergent.

[0077] For some examples, see Figure 9 The end of the second water channel 50A is formed with a diameter-reducing section 22 to increase the flow rate at the outlet of the second water channel 50A. As an optional embodiment, the interior of the mouth 202 is formed with a diameter-reducing section 22.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] 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.

[0082] For some examples, see Figure 9 and Figure 12 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] For some examples, see Figure 8The nozzle unit 200 further includes a first joint pipe 204 and a second joint pipe 205 , which are respectively connected to the shell 201 , 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 .

[0089] 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.

[0090] For some examples, see Figure 1 The nozzle unit 200 is arranged on the door sealing ring 60, and the water outlet 201b is used to directly release the detergent mixed solution into the clothing processing chamber, which is beneficial to improving the cleaning effect.

[0091] The above-mentioned direct delivery into the clothing processing chamber means that after the detergent mixed solution is discharged from the water outlet 201b, it is spontaneously sprayed into the space of the clothing processing chamber without the aid of an additional pipeline structure, which can achieve a spraying effect and expand the contact area between the detergent components and the clothes to be processed.

[0092] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0093] 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.
