[0001] The present application relates to the field of clothes treatment, and in particular to a detergent dispensing device and clothes treatment apparatus. BACKGROUND
[0002] In the related art, a clothes treatment apparatus includes a clothes treatment drum, a detergent box, and a pipeline. The pipeline connects the detergent box and the clothes treatment drum. When washing clothes, an external water flow is introduced into the detergent box to form a detergent mixed solution, which is finally introduced into the clothes treatment drum through the pipeline to add the detergent. However, the detergent is often not fully dissolved and mixed with the water flow, resulting in that the detergent is not fully utilized, the washing effect is poor, and the user experience is affected. Especially when the detergent is laundry powder, the pipeline is easily blocked, affecting the reliability of the clothes treatment apparatus. SUMMARY
[0003] Therefore, the embodiments of the present application aim to provide a detergent dispensing device and clothes treatment apparatus, which is beneficial to the dissolution of the detergent, improves the washing effect, and has good reliability.
[0004] The embodiments of the present application provide a detergent dispensing device, which includes:
[0005] The detergent supply assembly includes a first drain, a detergent dispensing cavity, a partition structure, and a first bottom wall portion. The partition structure is arranged above the first bottom wall portion, and the space between the two defines a mixing cavity. The first drain is in communication with the mixing cavity.
[0006] The detergent mixed solution discharged from the detergent dispensing cavity flows through the partition structure and enters the mixing cavity. The fluid in the mixing cavity is discharged through the first drain.
[0007] In some embodiments, the partition structure has a plurality of through holes. The through holes are in communication with the mixing cavity. The through holes are used to filter the detergent mixed solution discharged from the detergent dispensing cavity and discharge the filtered detergent mixed solution into the mixing cavity.
[0008] In some embodiments, the first end of the partition structure in a first direction is used to receive the detergent mixed solution discharged from the detergent dispensing cavity. The partition structure extends downwardly and inclines away from the first end in the first direction.
[0009] In some embodiments, the bottom wall of the detergent dispensing cavity is arranged above the partition structure. The bottom wall of the detergent dispensing cavity is arranged to be inclined, which is used to guide the detergent mixed solution of the detergent dispensing cavity to the first end of the partition structure.
[0010] In some embodiments, the first drain is arranged at one end of the first bottom wall portion in the first direction, and the first bottom wall portion extends downwardly and inclines toward the first drain in the first direction.
[0011] In some embodiments, the detergent supply assembly comprises an overflow cavity for receiving the detergent mixture solution overflowing from the mixing cavity, and a second drain for draining the detergent mixture solution in the overflow cavity out of the detergent dispenser, and the partition structure extends downwardly and inclines toward the overflow cavity in the first direction, so as to guide the substances on the top surface of the partition structure that do not pass through the through hole to the overflow cavity.
[0012] In some embodiments, the detergent supply assembly has a spacing structure.
[0013] The overflow cavity and the mixing cavity are respectively located on opposite sides of the spacing structure, and the partition structure extends above the spacing structure; or the partition structure extends to the surface of the side of the spacing structure toward the mixing cavity, and the top surface of the partition structure is not lower than the top edge of the spacing structure.
[0014] In some embodiments, the detergent supply assembly comprises a detergent box.
[0015] The first bottom wall portion constitutes a part of the bottom wall of the detergent box, the partition structure is arranged inside the detergent box and is in a separate structure with the detergent box; or the partition structure constitutes a part of the bottom wall of the detergent box, the first bottom wall portion is in a separate structure with the detergent box, and the first bottom wall portion is arranged outside the detergent box.
[0016] In some embodiments, the detergent dispenser comprises a mixing space, a water outlet, and a first water path and a second water path for conveying fluid.
[0017] The first water path is connected to a water source, the first drain, and the mixing space; the second water path is connected to the water source and the mixing space; the fluids in the first water path and the second water path converge in the mixing space, and the fluid in the mixing space is sprayed into a laundry treatment cavity of a laundry treatment apparatus through the water outlet.
[0018] The present application also provides a laundry treatment apparatus, comprising:
[0019] a laundry treatment cavity;
[0020] and the detergent dispenser for dispensing the detergent mixture solution into the laundry treatment cavity.
[0021] The detergent dispensing device provided in this application embodiment has a detergent mixture solution discharged from the detergent dispensing chamber. Under the influence of gravity, the solution passes through a partition structure into a mixing chamber below, and then flows out of the detergent supply component from the first drain outlet. During this process, the partition structure acts as a filter for the detergent mixture solution. On one hand, when the detergent is laundry powder, it is prone to clumping due to insufficient solvent or moisture. The partition structure can intercept at least some of the laundry powder clumps, reducing the likelihood of them clogging the first drain outlet and downstream structures after entering the mixing chamber, thus improving the reliability of the detergent dispensing device. On the other hand, the partition structure and the first bottom wall are both inclined, which facilitates the flow of the detergent mixture solution and promotes the sliding of laundry powder clumps from the partition structure into the overflow chamber.

In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example.
[0041] The present application provides a detergent dispensing device 100, please refer to Figure 7 The detergent dispensing device 100 comprises a detergent supply assembly 30. The detergent supply assembly 30 comprises a first drain 30b, a detergent dispensing cavity 30A, a partition structure 302, and a first bottom wall 303.
[0042] The present application also provides a laundry treatment apparatus, which comprises a laundry treatment cavity and the detergent dispensing device 100 of any of the embodiments of the present application. The laundry treatment cavity is used to accommodate laundry to be treated, and the detergent dispensing device 100 is used to dispense a detergent mixed solution into the laundry treatment cavity.
[0043] The laundry treatment apparatus is not limited in form, and can be a drum washing machine, an impeller washing machine, a drum washing and drying all-in-one machine, an impeller washing and drying all-in-one machine, etc. The present specification takes a drum washing machine as an example for description.
[0044] Exemplarily, please refer to Figure 1 The laundry treatment apparatus comprises a drum assembly 10 and a door seal ring 60 arranged at the front side of the drum assembly 10. A communication space composed of the inside of the drum assembly 10 and the radially inner side of the door seal ring 60 constitutes a laundry treatment cavity (not shown in the figure).
[0045] Please refer to Figure 4 and Figure 7The partition structure 302 is arranged above the first bottom wall portion 303, and a space between the two defines a mixing cavity 30B. The first drain 30b is in communication with the mixing cavity 30B. That is, the top surface of the first bottom wall portion 303 constitutes the bottom wall of the mixing cavity 30B, and the bottom surface of the partition structure 302 constitutes the top wall of the mixing cavity 30B. The partition structure 302 is in the form of a plate, but is not limited to be a straight or curved plate.
[0046] The detergent mixed solution discharged from the detergent dispensing cavity 30A flows through the partition structure 302 and enters the mixing cavity 30B. The fluid in the mixing cavity 30B is discharged through the first drain 30b and finally enters the laundry treatment cavity of the laundry treatment apparatus.
[0047] It should be noted that the detergent mixed solution mentioned in the present specification is merely for the convenience of description, and refers to a mixed solution in which detergent is dissolved, and the mass percentage concentration is not limited, and it is not limited that the detergent is completely dissolved. The form of the detergent is not limited, and can be a powder such as laundry detergent, or a flowable laundry liquid or softener. The detergent in the detergent dispensing cavity 30A is mixed with the fluid to form the detergent mixed solution. In addition, the dashed arrows in the drawings of the present specification all indicate the flow direction of the fluid.
[0048] The way in which the detergent mixed solution flows through the partition structure 302 and enters the mixing cavity 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 through holes in communication with the mixing cavity 30B, and the shape and number of the through holes are not limited, and the detergent mixed solution flows into the mixing cavity 30B from the through holes.
[0049] In the detergent dispensing device provided by the embodiments of the present application, the partition structure 302 is arranged, on the one hand, the flow path of the detergent mixed solution from the formation in the detergent dispensing cavity 30A to the discharge from the first drain 30b is longer, and the mixing effect between the detergent and the fluid is better; on the other hand, when the detergent is laundry detergent, due to insufficient dissolution or the influence of dampness and other factors, it is easy to form laundry detergent blocks. When the detergent mixed solution flows through the partition structure 302, at least part of the laundry detergent blocks remain on the partition structure 302 due to the difference in properties between solids and liquids, thereby reducing the probability of blockage of downstream structures due to laundry detergent blocks and improving the reliability of the detergent dispensing device.
[0050] In some embodiments, the partition structure 302 has a plurality of through holes, and the through holes are in communication with the mixing cavity 30B. The through holes are used to filter the detergent mixed solution discharged from the detergent dispensing cavity 30A, and discharge the filtered detergent mixed solution into the mixing cavity 30B.
[0051] The detergent mixed solution in the detergent dispensing cavity 30A is discharged, and then, under the action of gravity, filtered through the partition structure 302 and enters the mixing cavity 30B below, and then flows out of the detergent supply assembly 30 from the first drain port 30b. During this process, the partition structure 302 can filter the detergent mixed solution. On the one hand, because the partition structure 302 has a plurality of through holes, it can promote the mixing of the detergent mixed solution with air when passing through the partition structure 302, thereby increasing the foaming effect of the detergent. On the other hand, when the detergent is washing powder, the partition structure 302 can intercept washing powder blocks with a size larger than the through holes, thereby reducing the probability of clogging the first drain port 30b and downstream structures after entering the mixing cavity 30B, and further improving the reliability of the detergent dispensing device 100.
[0052] Exemplarily, the diameter of the through hole is 2mm-3.5mm (millimeters), including but not limited to 2mm, 2.5mm, 3mm, 3.5mm, etc. In this way, the washing powder blocks can be better intercepted, and the flow of the detergent mixed solution into the mixing cavity 30B is less affected. The diameters of the through holes can be the same or different.
[0053] It should be noted that the form of the partition structure 302 is not limited. Exemplarily, the partition structure 302 can be a straight plate (as shown in Figure 4 ), or a groove, etc.
[0054] In some embodiments, referring to 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 dispensing cavity 30A. The partition structure 302 extends downwardly away from the first end in the first direction, i.e., 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, thereby reducing the number of through holes clogged by the washing powder blocks, so that the flow of the detergent mixed solution into the mixing cavity 30B is less affected.
[0056] In addition, the detergent mixed solution discharged from the detergent dispensing cavity 30A also flows on the partition structure 302 from the first end of the partition structure 302 along the first direction, which can flush the residual washing powder blocks on the partition structure 302, promote the dissolution of the washing powder, so that its size becomes small enough to easily pass through the through holes and enter the mixing cavity 30B.
[0057] In some embodiments, referring to Figure 7The bottom wall 304 of the detergent dispensing chamber 30A is disposed above the partition structure 302, and is inclined to guide the detergent mixture solution discharged from the detergent dispensing chamber 30A to the first end of the partition structure 302.
[0058] That is, after the detergent mixture solution in the detergent dispensing chamber 30A is discharged, it flows down along the second bottom wall 304 and flows downward from the first end of the partition structure 302 in the first direction. In this way, the detergent dispensing chamber 30A does not need to be provided with an additional drainage pipeline, but the second bottom wall 304 in the detergent supply assembly 30 guides the detergent mixture solution to the partition structure 302, so that the structure in the detergent supply assembly 30 is more compact.
[0059] Exemplarily, in some embodiments, the detergent supply assembly 30 includes a detergent box 31 and a dispenser box 32, the dispenser box 32 is pullably disposed in the detergent box 31, the detergent dispensing chamber 30A is formed in the dispenser box 32, and the user can pull out the dispenser box 32 to put the detergent needed for washing, and the second bottom wall 304 and the partition structure 302 are both disposed inside the detergent box 31. In the front-to-rear direction of the laundry treatment apparatus, the dispenser box 32 can be pulled and moved, the second bottom wall 304 extends downwardly and obliquely in the direction from the rear to the front, and the partition structure 302 extends downwardly and obliquely in the direction from the front to the rear and is disposed below the second bottom wall 304. In this way, the size of the detergent supply assembly 30 in the front-to-rear direction is small, which can save space and also make the flow path of the detergent mixture solution in the detergent supply assembly 30 longer and the dissolving effect better.
[0060] In some embodiments, referring to Figure 7 The first drainage opening 30b is disposed at one end of the first bottom wall 303 in the first direction, and the first bottom wall 303 extends downwardly and obliquely in the direction close to the first drainage opening 30b in the first direction. In this way, the fluid in the mixing chamber 30B spontaneously concentrates at the first drainage opening 30b and is discharged from the detergent supply assembly 30, without the need to set an additional device to provide power for the flow of the detergent mixture solution, and such a setting can accelerate the discharge of the detergent mixture solution.
[0061] It should be noted that the inclination directions of the first bottom wall 303 and the partition structure 302 can be the same, but the inclination angles thereof can be different. For example, compared with the first bottom wall 303, the partition structure 302 is more inclined, which is beneficial to the displacement of the detergent block; or compared with the partition structure 302, the first bottom wall 303 is more inclined, which is beneficial to the rapid discharge of the detergent mixture solution.
[0062] Exemplarily, in some embodiments, the first drainage opening 30b is located at the lowest point in the mixing chamber 30B.
[0063] In some embodiments, referring to Figure 5 and Figure 6 , the detergent supply assembly 30 comprises an overflow cavity 30C for receiving the detergent mixture solution overflowing from the mixing cavity 30B and a second drain 30a for draining the detergent mixture solution in the overflow cavity 30C out of the detergent dispensing device 100. For example, the laundry treatment apparatus further comprises a water inlet pipe 70, the water inlet end of which is connected to the second drain 30a and the water outlet end of which is connected to the drum assembly 10, so as to pass the fluid in the overflow cavity 30C into the laundry treatment cavity. That is, the overflow cavity 30C and the second drain 30a serve to protect the detergent dispensing device 100 and assist water inlet.
[0064] Referring to Figure 7 , the baffle structure 302 extends downwardly along the first direction towards the overflow cavity 30C, so as to guide the substances (e.g. detergent blocks) on the top surface of the baffle structure 302 that do not pass through the through holes to the overflow cavity 30C. It can be understood that the overflow cavity 30C is located on one side of the mixing cavity 30B along the first direction, and the intercepted substances on the baffle structure 302 that do not pass through the through holes can enter the overflow cavity 30C along the first direction and be drained out of the detergent dispensing device 100 through the second drain 30a, so that the detergent blocks remaining on the baffle structure 302 are less, and the reliability of the detergent dispensing device 100 is improved.
[0065] It should be noted that the second drain 30a has a large size and is almost free of clogging risk. For example, in some embodiments, the size of the first drain 30b is smaller than that of the second drain 30a.
[0066] In some embodiments, referring to Figure 5 , the detergent supply assembly 30 has a partition structure 301, and the overflow cavity 30C and the mixing cavity 30B are respectively located on opposite sides of the partition structure 301, so that the internal structure of the detergent supply assembly 30 is compact.
[0067] In some embodiments, the baffle structure 302 extends above the partition structure 301, which is beneficial for the detergent blocks on the baffle structure 302 to displace and pass over the partition structure 301 to enter the overflow cavity 30C. In another part of the embodiments, the baffle structure 302 extends to the surface of the partition structure 301 towards the mixing cavity 30B, and the top surface of the baffle structure 302 is not lower than the top edge of the partition structure 301, which is beneficial for the detergent blocks on the baffle structure 302 to displace and pass over the partition structure 301 to enter the overflow cavity 30C.
[0068] The first bottom wall part 303 and the forming manner of the partition structure 302 are not limited. For example, in some embodiments, the first bottom wall part 303 constitutes part of the bottom wall of the detergent box 31, the partition structure 302 is arranged in the interior of the detergent box 31, and the partition structure 302 is in a separate structure from the detergent box 31. That is, the detergent box 31 and the first bottom wall part 303 are in an integrated structure, and the structural reliability of the detergent supply assembly 30 can be improved, and the partition structure 302 is a separate component and is detachably arranged in the interior of the detergent box 31.
[0069] In other embodiments, the partition structure 302 constitutes part of the bottom wall of the detergent box 31, the first bottom wall part 303 is in a separate structure from the detergent box 31, and the first bottom wall part 303 is arranged outside the detergent box 31. That is, the detergent box 31 and the partition structure 302 are in an integrated structure, for example, a through hole is formed in the bottom wall of the detergent box 31 to define the partition structure 302, and the first bottom wall part 303 is a separate component and is detachably arranged outside the detergent box 31.
[0070] In some embodiments, referring to Figure 10 and Figure 11 , the detergent dispensing device 100 comprises a mixing space, a water outlet 201b, and a first water path 40A and a second water path 50A for conveying fluid. The first water path 40A is connected to the water source, the first drain 30b, and the mixing space, and the second water path 50A is connected to 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 30b enters the first water path 40A, and the fluid in the first water path 40A is a detergent mixed solution; or the detergent dispensing cavity 30A is located on the first water path 40A, and the fluid supplied by the water source enters the detergent dispensing cavity 30A along the first water path 40A, and is mixed and dissolved with the detergent to form a detergent mixed solution. The fluid in the second water path 50A is not limited, which can be tap water or fluid dissolved with detergent components. For example, in some embodiments, the laundry treatment apparatus further comprises a circulating pump, and the water inlet end of the second water path 50A is connected to the circulating pump. In other embodiments, as shown in Figure 2 and Figure 3 , the laundry treatment apparatus further comprises 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.
[0072] The fluids of the first water path 40A and the second water path 50A converge in the mixing space, and the fluid in the mixing space is sprayed into the laundry treatment cavity of the laundry treatment apparatus through the water outlet 201b. The two fluids impact and mix with each other in the mixing space, which can promote the dissolution of the detergent components, make the detergent components in the detergent mixed solution more uniform, and improve the washing ratio of the laundry treatment apparatus.
[0073] In some embodiments, referring to Figure 8 , Figure 11 and Figure 12 , the detergent dispensing device 100 comprises a nozzle unit 200, the nozzle unit 200 comprises a shell part 201 and a nozzle part 202, the shell part 201 has a mixing space formed inside, a water outlet 201b is formed on the wall of the mixing space, the nozzle part 202 is located inside the mixing space, and the outlet of the nozzle part 202 constitutes the water outlet end of the second waterway 50A, and the outlet of the nozzle part 202 sprays water towards the water outlet 201b.
[0074] The nozzle part 202 is arranged inside the shell part 201, and the nozzle part 202 extends into the mixing space, the fluid of the second waterway 50A enters the mixing space through the nozzle part 202, that is, the water outlet section of the water outlet end of the second waterway 50A is away from the wall of the mixing space by a certain distance, so that the nozzle part 202 can suck the fluid from the first waterway 40A when spraying the fluid, so as to realize further mixing of the fluid of the first waterway 40A and the fluid of the second waterway 50A.
[0075] The above-mentioned sucking of the fluid from the first waterway 40A means that under the action of the viscosity and flow rate difference of the fluid, the fluid from the first waterway 40A is concentrated to the nozzle part 202 when the nozzle part 202 sprays the fluid, so as to improve the mixing effect of the fluid of the first waterway 40A and the fluid of the second waterway 50A.
[0076] As an optional embodiment, the nozzle part 202 sprays water towards the water outlet 201b, so that the distance from the second waterway 50A to the outlet of the water outlet 201b is shorter, the dispersion of the water outlet form of the water outlet end of the second waterway 50A can be reduced, and the air of the external environment is easily sucked into the mixing space, so as to improve the foaming effect of the detergent.
[0077] In some embodiments, referring to Figure 9 , the end of the second waterway 50A is formed with a reduced-diameter section 22, so that the flow rate of the water outlet end of the second waterway 50A is increased. As an optional embodiment, the inside of the nozzle part 202 is formed with the reduced-diameter section 22.
[0078] Exemplarily, in some embodiments, the end of the reduced-diameter section 22 constitutes the water outlet end of the second waterway 50A. That is, the fluid of the second waterway 50A is sprayed from the end of the reduced-diameter section 22. In other embodiments, the end of the reduced-diameter section 22 is further connected with a constant-diameter section and / or an enlarged-diameter section, the constant-diameter section and / or the enlarged-diameter section constitute the water outlet end of the second waterway 50A, and the fluid of the second waterway 50A is sprayed from the end of the constant-diameter section or the enlarged-diameter section.
[0079] It should be noted that, along the movement direction of the fluid, the flow area of the fluid in the above-mentioned reduced diameter section 22 decreases, the flow area of the fluid in the above-mentioned constant diameter section is basically unchanged, and the flow area of the fluid in the above-mentioned expanded diameter section increases.
[0080] The reduced diameter section 22 can increase the impact force of the fluid by limiting the flow area when the fluid is sprayed, and a greater impact force of the fluid on the water outlet end of the first waterway 40A is generated, thereby achieving a better mixing effect.
[0081] Meanwhile, the reduced diameter section 22 enables the water outlet end of the second waterway 50A to have a greater jet speed, and can generate a significant negative pressure in a relatively large surrounding area, so that the fluid at the water outlet end of the first waterway 40A is sucked and mixed with the fluid of the second waterway 50A under the action of the negative pressure, thereby improving the mixing and foaming effect.
[0082] In some embodiments, referring to Figure 9 and Figure 12 , the laundry treating apparatus includes a turbulence structure 21 arranged in the second waterway 50A and configured to provide a circumferential velocity component to the fluid in the second waterway 50A.
[0083] The above-mentioned provision of the circumferential velocity component means that the component of the velocity direction of the fluid in the second waterway 50A after passing through the turbulence structure 21 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.
[0084] In this embodiment, the turbulence structure 21 enables part of the fluid to have both a movement speed in the circumferential direction and a speed to continue to flow forward, so that the part of the fluid basically presents a spiral movement, and when the fluid is sprayed from the water outlet end of the second waterway 50A, the fluid is facilitated to present a conical diffusion, thereby achieving a wider radiation range and a better visual effect.
[0085] Exemplarily, the turbulence structure 21 includes one or more spiral blades, and the spiral blades separate at least part of the length of the second waterway 50A into a plurality of sub-flow channels.
[0086] The above-mentioned plurality means that the number of blades is a plurality, which can be two, three or more, that is, the number of spiral lines is not less than two, and is not limited to the number of turns of the spiral line.
[0087] After the fluid passes through the spiral blade, the fluid presents a spiral movement, the spiral blade structure is simple, has a good flow disturbance effect on the fluid, and has small resistance, thereby reducing the energy loss of the fluid when passing through.
[0088] In some embodiments, referring to Figure 8The spray head unit 200 further comprises a first joint pipe 204 and a second joint pipe 205, which are respectively connected to the shell part 201, the first water path 40A flows through the first joint pipe 204, and the second water path 50A flows through the second joint pipe 205.
[0089] The first joint pipe 204 can serve as a mounting structure for connecting the spray head unit 200 to the first water path 40A, and the second joint pipe 205 can serve as a mounting structure for connecting the spray head unit 200 to the second water path 50A. Exemplarily, the first water path 40A and the second water path 50A are each composed of one or more pipes, a part of the pipes being connected to the first joint pipe 204 and another part of the pipes being connected to the second joint pipe 205, so as to realize the flow of fluid into the spray head unit 200.
[0090] In some embodiments, referring to Figure 1 The spray head unit 200 is arranged on the door seal 60, and the water outlet 201b is used to directly pour the detergent mixed solution into the clothes treatment cavity, which is beneficial to improve the washing effect.
[0091] The above-mentioned direct pouring into the clothes treatment cavity means that after the detergent mixed solution is discharged from the water outlet 201b, it does not need to rely on an additional pipeline structure, but is spontaneously sprayed into the space of the clothes treatment cavity, which can have a spraying effect and expand the contact area of the detergent components and the clothes to be treated.
[0092] The various embodiments / implementation manners provided in the present application can be combined with each other without contradiction.
[0093] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
