[0032] The present application provides a detergent dispensing device. Figures 1 to 6 The detergent dispensing device 10 includes a detergent box 11, a dispenser box 12, and a filter 13. The detergent box 11 is provided with a mixing chamber 11a and a first drain port 11c. The first drain port 11c is provided on the wall of the mixing chamber 11a. The dispenser box 12 is disposed within the detergent box 11 and defines a detergent dispensing chamber 12a. The filter 13 is disposed within the detergent box 11 and has a through hole 13a. The detergent and / or detergent mixed solution discharged from the detergent dispensing chamber 12a can enter the mixing chamber 11a through the through hole 13a.
[0033] An embodiment of the present application also provides a clothing processing device, and the type of the clothing processing device is not limited, for example, it can be a washing machine, a washer-dryer, etc.
[0034] See also Figures 1 to 4 The laundry processing device includes a laundry processing chamber and a detergent dispensing device 10 in any embodiment of the present application. The first drain port 11c of the detergent dispensing device 10 is connected to the laundry processing chamber. The first drain port 11c is used to guide the mixed solution in the mixing chamber 11a to the laundry processing chamber.
[0035] It should be noted that the detergent mixed solution mentioned in this specification is only for the convenience of description and refers to a solution in which detergent is dissolved. Its mass percentage concentration is not limited. Of course, the detergent mixed solution is not limited to a solution in which the detergent is completely dissolved.
[0036] The form of the detergent is not limited, and it can be powdered laundry detergent, flowable laundry liquid, flowable softener, etc.
[0037] Exemplarily, the detergent dispensing device 10 further includes a water channel that flows through the detergent dispensing chamber 12a and the first drain port 11c. Fluid introduced into the water channel enters the detergent dispensing chamber 12a, mixes with the detergent, forms a detergent mixed solution, and is discharged from the detergent box 11 through the first drain port 11c.
[0038] It should be noted that the above-mentioned water source refers to a water source that supplies fluid to the water channel, such as tap water; it can also be an internal water source of the clothing processing equipment, such as circulating water.
[0039] For some examples, see Figure 4 The dispenser box 12 is pullable inside the detergent box 11 . For example, the dispenser box 12 can be at least partially pulled out of the detergent box 11 to the outside of the detergent box 11 along a horizontal direction.
[0040] Exemplarily, the detergent box 11 is provided with a draw-out opening 11 e , and the dispenser box 12 is drawably disposed in the detergent box 11 along a first direction through the draw-out opening 11 e .
[0041] It should be noted that in the embodiments of the present application, the waterway refers to the flow path of the fluid, and does not specifically refer to a pipeline structure.
[0042] The detergent box 11 further comprises a mixing chamber 11a for receiving the fluid flowing through the detergent delivery chamber 12a, and a first drain port 11c provided on the wall of the mixing chamber 11a. That is, the mixed liquid containing detergent enters the mixing chamber 11a and is discharged from the first drain port 11c.
[0043] For example, see Figure 4 The mixing chamber 11a is located below the dispenser box 12, and the detergent mixed solution flows from the detergent delivery chamber 12a of the dispenser box 12 to the mixing chamber 11a below the dispenser box 12, and is discharged from the first drain port 11c.
[0044] For some examples, see Figures 2 to 5 The detergent box 11 also has an overflow chamber 11b and a second drain port 11d. The overflow chamber 11b is used to receive the detergent mixed solution overflowing from the mixing chamber 11a. The second drain port 11d is used to discharge the detergent mixed solution in the overflow chamber 11b out of the detergent box 11.
[0045] In this embodiment, when the water level in the mixing chamber 11a is not higher than the overflow level, the fluid in the mixing chamber 11a is discharged from the first drain port 11c and flows into the barrel assembly 20. When the water level in the mixing chamber 11a is higher than the overflow level, the excess water overflows into the overflow chamber 11b and is discharged from the second drain port 11d. In other words, the detergent box 11 preferentially discharges water from the first drain port 11c, and the second drain port 11d serves as a safety protection, allowing the excess water in the mixing chamber 11a to be discharged in a timely manner.
[0046] Exemplarily, the fluid cross-sectional area of the second drain outlet 11d is greater than that of the first drain outlet 11c. That is, when the amount of water is equally sufficient, the drainage volume of the second drain outlet 11d is greater than the drainage flow rate of the first drain outlet 11c.
[0047] Since the fluid cross-sectional area of the first drain port 11c is small, the water flow rate of the first drain port 11c is relatively small. However, the second drain port 11d and the overflow chamber 11b can promptly discharge the fluid in the detergent box in the event of overflow, thereby alleviating water congestion in the detergent box 11 and providing safety protection.
[0048] Here, the detergent mixed solution discharged from the detergent dispensing chamber 12a is a laundry liquid mixed solution or a laundry powder mixed solution, particularly a laundry powder mixed solution. Because laundry powder is a powdered detergent, it is more susceptible to clogging and residue than laundry liquid, potentially reducing the reliability of the detergent dispensing device 10. By providing the filter 13, the detergent mixed solution discharged from the detergent dispensing chamber 12a passes through the through hole 13a and enters the mixing chamber 11a. In other words, the filter 13 can filter the detergent mixed solution.
[0049] It should be noted that the specific structure of the filter element 13 is not limited here. For example, the filter element 13 is a filter plate.
[0050] For example, see Figure 4 At least a portion of the dispenser box 12 is spaced apart from the side wall of the detergent box 11 to form a flow port 11n, and the detergent and / or detergent mixed solution in the detergent delivery chamber 12a can be discharged from the detergent delivery chamber 12a through the flow port 11n.
[0051] Here, when projected on a plane perpendicular to the height direction of the detergent dispensing device 10, there is no through-hole 13a within the projection range of the flow port 11n. After the detergent mixed solution passes through the flow port 11n and is discharged from the detergent dispensing chamber 12a, it will not directly flow into the mixing chamber 11a from the corresponding through-hole 13a within the projection range of the flow port 11n. This is beneficial to increasing the flow path of the detergent mixed solution between the flow port 11n and the through-hole 13a.
[0052] It should be noted that the height direction of the detergent dispensing device 10 is the height direction of the clothes processing equipment.
[0053] The detergent dispensing device provided in the embodiment of the present application, by arranging a filter element 13 in the detergent box 11, can allow the detergent mixed solution discharged from the detergent dispensing chamber 12a to enter the mixing chamber 11a through the through hole 13a of the filter element 13. In this way, on the one hand, before the detergent enters the clothing processing chamber, it can further promote the dissolution of the detergent and improve the mixing uniformity of the detergent and water, thereby improving the utilization efficiency of the detergent; on the other hand, the filter element 13 can filter large-particle washing powder, which can further promote the dissolution of the detergent while improving the situation where large-particle washing powder blocks the first drain outlet 11c.
[0054] In some embodiments, see Figures 2 to 5 The detergent box 11 includes a first sub-wall 111 and a second sub-wall 112 arranged along the second direction. The first sub-wall 111 and the second sub-wall 112 are connected. An end of the first sub-wall 111 close to the second sub-wall 112 is lower than an end of the first sub-wall 111 away from the second sub-wall 112 in the height direction of the detergent dispensing device 10. An end of the second sub-wall 112 close to the first sub-wall 111 is lower than an end of the second sub-wall 112 away from the first sub-wall 111 in the height direction of the detergent dispensing device 10. The first sub-wall 111 and the second sub-wall 112 define at least a portion of the mixing chamber 11a.
[0055] Exemplarily, both the first sub-wall 111 and the second sub-wall 112 extend along the first direction.
[0056] The intersection of the first direction and the second direction means that the first direction and the second direction are not parallel. Exemplarily, the first direction and the second direction are perpendicular to each other.
[0057] For example, the first direction is the direction in which the dispenser box 12 is pulled out, or in other words, the direction in which the dispenser box 12 slides. Accordingly, the height direction of the detergent dispenser 10 corresponds to the direction of gravity, and the first direction and the height direction of the detergent dispenser 10 are perpendicular to each other. Accordingly, the second direction is perpendicular to both the height direction of the detergent dispenser 10 and the first direction.
[0058] It should be noted that the first sub-wall 111 and the second sub-wall 112 defining at least a portion of the mixing chamber 11a means that the first sub-wall 111 and the second sub-wall 112 may define a portion of the mixing chamber 11a or the entire mixing chamber 11a.
[0059] Here, the end of the first sub-wall 111 close to the second sub-wall 112 is lower than the end of the first sub-wall 111 away from the second sub-wall 112 in the height direction of the detergent dispensing device 10, that is, the first sub-wall 111 is inclined along the second direction, and the end of the second sub-wall 112 close to the first sub-wall 111 is lower than the end of the second sub-wall 112 away from the first sub-wall 111 in the height direction of the detergent dispensing device 10, that is, the second sub-wall 112 is inclined along the second direction. In other words, the connection between the first sub-wall 111 and the second sub-wall 112 is lower than the surrounding area, that is, the bottom wall of the detergent box 11 is roughly V-shaped. In this way, by setting the first drain outlet 11c at the connection between the first sub-wall 111 and the second sub-wall 112, it is beneficial for the detergent mixed solution in the mixing chamber 11a to be guided to the barrel assembly 20 through the first drain outlet 11c as much as possible.
[0060] The first sub-wall 111 is arranged to be inclined along the second direction. Part of the first sub-wall 111 may be arranged to be inclined along the second direction, or all of the first sub-wall 111 may be arranged to be inclined along the second direction.
[0061] Likewise, the second sub-wall 112 is arranged to be tilted along the second direction. Part of the second sub-wall 112 may be arranged to be tilted along the second direction, or all of the second sub-wall 112 may be arranged to be tilted along the second direction.
[0062] In this embodiment, by setting the end of the first sub-wall 111 close to the second sub-wall 112 to be lower than the end of the first sub-wall 111 away from the second sub-wall 112 in the height direction of the detergent dispensing device 10, and setting the end of the second sub-wall 112 close to the first sub-wall 111 to be lower than the end of the second sub-wall 112 away from the first sub-wall 111 in the height direction of the detergent dispensing device 10, the first drain outlet 11c can be set at the connection between the first sub-wall 111 and the second sub-wall 112, which is conducive to the detergent mixed solution in the mixing chamber 11a being guided to the barrel assembly 20 through the first drain outlet 11c as much as possible, thereby improving the utilization efficiency of the detergent.
[0063] In some embodiments, see Figure 5 and Figure 6 The filter element 13 includes an open area 13b having through-holes 13a and a non-porous area 13c having no through-holes 13a. When projected onto a plane perpendicular to the height of the detergent dispenser 10, the projection of the junction between the first sub-wall 111 and the second sub-wall 112 at least partially overlaps with the projection of the non-porous area 13c.
[0064] Here, the filter element 13 can be divided into an open hole area 13b and a non-porous area 13c, wherein the open hole area 13b is provided with through holes 13a, and the non-porous area 13c is not provided with through holes 13a.
[0065] That the projection of the connection between the first sub-wall 111 and the second sub-wall 112 at least partially overlaps with the projection of the non-porous area 13c means that the projection of the connection between the first sub-wall 111 and the second sub-wall 112 and the projection of the non-porous area 13c may be partially overlapping or partially non-overlapping; or the projection of the connection between the first sub-wall 111 and the second sub-wall 112 and the projection of the non-porous area 13c may completely overlap.
[0066] It can be understood that the detergent mixed solution discharged from the detergent delivery chamber 12a is a laundry liquid mixed solution or a laundry powder mixed solution, especially a laundry powder mixed solution. Since laundry powder is a powdered detergent, if a through hole 13a is provided at the connection between the first sub-wall 111 and the second sub-wall 112 in the area corresponding to the filter element 13, the laundry powder is more likely to be directly deposited through the through hole 13a there and remain at the connection between the first sub-wall 111 and the second sub-wall 112, which may reduce the utilization rate of the detergent.
[0067] In this embodiment, the projection of the connection between the first sub-wall 111 and the second sub-wall 112 does not exceed the projection range of the non-porous area 13c, that is, no through-hole 13a is provided in the area of the filter element 13 corresponding to the connection between the first sub-wall 111 and the second sub-wall 112, thereby improving the situation in which the washing powder is directly deposited through the through-hole 13a and remains at the connection between the first sub-wall 111 and the second sub-wall 112, thereby improving the utilization rate of the detergent.
[0068] In some embodiments, the projection of the connection between the first sub-wall 111 and the second sub-wall 112 does not exceed the projection range of the non-porous area 13 c.
[0069] In some embodiments, see Figure 6 , the size of the non-porous area 13c in the second direction is 2mm-20mm.
[0070] For example, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, and so on.
[0071] It can be understood that, the smaller the size of the non-porous area 13c in the second direction, the more through holes 13a can be set on the filter element 13, which is beneficial to improving the liquid passing efficiency; the larger the size of the non-porous area 13c in the second direction, the larger the distance between the connection between the first sub-wall 111 and the second sub-wall 112 and the open area 13b in the second direction, and the better the effect of improving the direct deposition and residue of washing powder at the connection between the first sub-wall 111 and the second sub-wall 112.
[0072] In this embodiment, by setting the size of the non-porous area 13c in the second direction to 2mm-20mm, the filter element 13 can have a certain liquid passing efficiency while further improving the situation where the washing powder is directly deposited and remains on the first sub-wall 111 and the second sub-wall 112.
[0073] In some embodiments, see Figure 2 and Figure 6 , open areas 13b are provided on both sides of the non-porous area 13c along the second direction.
[0074] Perforated regions 13b are provided on both sides of the non-perforated region 13c along the second direction. That is, there are multiple perforated regions 13b, and at least two perforated regions 13b are spaced apart in the second direction. For example, one perforated region 13b corresponds to the first sub-wall 111, and the other perforated region 13b corresponds to the second sub-wall 112.
[0075] In this embodiment, by providing open areas 13b on both sides of the non-porous area 13c along the second direction, the detergent mixed solution discharged from the detergent delivery chamber 12a can enter the mixing chamber 11a through the through holes 13a of the open areas 13b on both sides, and be guided to the clothing processing chamber through the first drain port 11c, thereby improving the situation in which the washing powder is directly deposited through the through holes 13a and remains at the connection between the first sub-wall 111 and the second sub-wall 112, which is conducive to improving the utilization rate of the detergent.
[0076] It should be noted that the specific manner in which the mixing chamber 11 a and the overflow chamber 11 b are arranged in the detergent box 11 is not limited here.
[0077] In some embodiments, see Figures 2 to 5 The bottom wall of the detergent box 11 is provided with a water retaining rib 113 and a second drain port 11d. The water retaining rib 113 separates the space within the detergent box 11 into a mixing chamber 11a and an overflow chamber 11b. The second drain port 11d is used to discharge the mixed detergent solution in the overflow chamber 11b out of the detergent dispensing device 10.
[0078] Exemplarily, the second drain port 11d is provided on the cavity wall of the overflow cavity 11b.
[0079] The overflow water level in the mixing chamber 11a is determined by the structure of the water retaining rib 113. Specifically, the overflow water level is the lowest water level at which the water retaining rib 113 allows the water in the mixing chamber 11a to flow into the overflow chamber 11b.
[0080] For example, in some embodiments, the height of the top edge of the water retaining rib 113 serves as the overflow water level of the mixing chamber 11a. When the water level in the mixing chamber 11a continues to rise to the top edge of the water retaining rib 113, the water overflows the water retaining rib 113, flows from the top side of the water retaining rib 113 to the overflow chamber 11b on the second side of the water retaining rib 113, and is discharged from the second drain outlet 11d.
[0081] In other embodiments, the water retaining rib 113 is provided with a notch, and the height of the bottom edge of the notch serves as the overflow water level of the mixing chamber 11 a.
[0082] It should be noted that the specific location of the filter element 13 is not limited here.
[0083] In some embodiments, see Figure 2 and Figure 5 The two ends of the filter 13 along the second direction are in contact with the first sub-wall 111 and the second sub-wall 112 respectively, and the two ends along the first direction are in contact with the side wall of the detergent box 11 and the water retaining rib 113 respectively.
[0084] That is, in some embodiments, the filter 13 , the first sub-wall 111 , the second sub-wall 112 , the side wall of the detergent box 11 , and the water retaining rib 113 together define a mixing chamber 11 a .
[0085] Here, the filter element 13 contacts the water retaining rib 113 , and the filter element 13 may be placed on the top of the water retaining rib 113 , or the filter element 13 may be in contact with the side wall of the water retaining rib 113 .
[0086] Exemplarily, a first side wall can also be provided at one end of the first sub-wall 111 away from the second sub-wall 112, and a second side wall can also be provided at one end of the second sub-wall 112 away from the first sub-wall 111, and the two ends of the filter element 13 along the second direction are in contact with the first side wall of the first sub-wall 111 and the second side wall of the second sub-wall 112 respectively.
[0087] In some embodiments, see Figure 6 The filter element 13 includes a main body and a thinned region. The thinned region is provided on at least a portion of the periphery of the main body. The thickness of the thinned region is less than that of the main body, and the thickness of the thinned region decreases as it moves away from the main body.
[0088] The provision of the thinned area on at least a portion of the circumference of the main body portion means that the thinned area may be provided on a portion of the circumference of the main body portion, or the thinned area may be provided on the entire circumference of the main body portion.
[0089] At least a portion of the circumference of the main body is provided with a thinned region, that is, the thickness of the edge of the filter element 13 is thinned.
[0090] In this embodiment, a thinned area is provided in at least a portion of the circumferential side of the main body, and the thickness of the thinned area decreases in the direction away from the main body. This helps to better fit the edge of the filter 13 to the detergent box 11, and can reduce the height of the step between the edge of the filter 13 and the detergent box 11, which helps to reduce the resistance of the detergent mixed solution in other areas of the detergent box 11 to the flow of the filter 13.
[0091] In some embodiments, see Figure 2 and Figure 6 The filter element 13 is detachably connected to the detergent box 11 .
[0092] Here, there are various specific ways to detachably connect the filter element 13 and the detergent box 11. For example, the filter element 13 and the detergent box 11 are connected by snapping, plugging or fastening.
[0093] It is understandable that after the detergent dispensing device 10 has been used for a period of time, the through hole 13 a of the filter 13 may be clogged, and detergent may be deposited in the detergent box 11 .
[0094] In this embodiment, by detachably connecting the filter element 13 to the detergent box 11 , the filter element 13 can be easily disassembled and assembled for cleaning, maintenance or replacement, thereby improving the user experience.
[0095] In some embodiments, see Figure 4 The detergent box 11 is provided with a pull-out opening 11e, and the dispenser box 12 is pullably arranged in the detergent box 11 through the pull-out opening 11e, and the filter 13 is tilted along the direction in which the dispenser box 12 is pulled out.
[0096] The filter 13 is arranged tilted along the direction in which the dispenser box 12 is pulled out, for example, the filter 13 is arranged tilted along the direction in which the dispenser box 12 is pushed into the detergent box 11 .
[0097] The dispenser box 12 is at least partially withdrawn from the detergent box 11 through the pull-out opening 11 e to the outside of the detergent box 11 for dispensing detergent into the detergent dispensing cavity 12 a , and then the dispenser box 12 is pushed into the detergent box 11 .
[0098] Exemplarily, the first drain port 11 c is provided on a side of the filter element 13 close to the drawer port 11 e .
[0099] In this embodiment, the filter element 13 is tilted along the direction in which the dispenser box 12 is pulled out, so that the detergent mixed solution discharged from the detergent delivery chamber 12a can flow along the downwardly tilted side of the filter element 13. During the flow process, the dissolution of the detergent can be further promoted, and the mixing uniformity of the detergent and water can be improved, thereby improving the utilization efficiency of the detergent.
[0100] In some embodiments, see Figure 4 The filter element 13 is tilted upward at an angle of 3°-10°.
[0101] For example, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, etc.
[0102] It can be understood that, when the length of the detergent dispensing device 10 remains the same, the greater the upward tilt angle of the filter element 13, the more conducive it is to increasing the filtration area of the filter element 13 and increasing the flow rate of the detergent mixed solution along the filter element 13, thereby improving the filtration efficiency of the filter element 13; the smaller the upward tilt angle of the filter element 13, the more conducive it is to reducing the height size of the detergent dispensing device 10 and improving the structural compactness of the detergent dispensing device 10.
[0103] In this embodiment, by setting the upward tilt angle of the filter element 13 to 3°-10°, while ensuring that the filter element 13 has a certain filtering efficiency, it is also beneficial to reduce the height size of the detergent dispensing device 10 and improve the structural compactness of the detergent dispensing device 10.
[0104] In some embodiments, see Figure 6 The aperture of the via hole 13a is 2mm-3.5mm.
[0105] For example, 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm, 3.1mm, 3.2mm, 3.3mm, 3.4mm, 3.5mm, and so on.
[0106] In this embodiment, by setting the aperture of the through hole 13a to 2mm-3.5mm, the filter element 13 can have a better filtering effect, improving the situation where large particles of washing powder block the first drain port 11c and the situation where the through hole 13a is blocked.
[0107] In some embodiments, see Figure 6 The spacing between adjacent via holes 13a is 3mm-10mm.
[0108] For example, 3mm, 3.3mm, 3.5mm, 3.8mm, 4mm, 4.5mm, 5mm, 5.7mm, 6mm, 6.2mm, 6.5mm, 7mm, 7.2mm, 7.8mm, 8mm, 8.5mm, 8.8mm, 9mm, 9.5mm, 10mm, etc.
[0109] The distance between adjacent via holes 13 a refers to the distance between any via hole 13 a and the nearest via hole 13 a , and is the distance between the centers of two adjacent via holes 13 a .
[0110] In this embodiment, by setting the distance between adjacent through holes 13a to 3 mm-10 mm, the filter element 13 can have a certain filtering efficiency while facilitating the molding of the filter plate.
[0111] For some examples, see Figure 1The laundry processing device includes a drum assembly 20, which includes an inner drum (not shown). Exemplarily, the drum assembly 20 also includes an outer drum 21, and the inner drum is rotatably disposed in the outer drum 21. The outer drum 21 is used to hold water for washing clothes, and the inner drum is used to hold clothes. In this embodiment, the inner drum holds water through the outer drum 21, and the inner drum can also be called a perforated inner drum. In other embodiments, the inner drum holds water by itself, and can also be called a non-perforated inner drum. The outer drum 21 can be set outside the inner drum, or it can be not set.
[0112] It is understandable that in some embodiments, the barrel assembly 20 may only have an inner barrel without the outer barrel 21. In this embodiment, the inner barrel is a hole-free inner barrel that can hold water.
[0113] For example, see Figure 1 The laundry processing device further includes a door (not shown), a housing (not shown), and a door seal 30 disposed on the front side of the drum assembly 20. The drum assembly 20 is disposed within the housing. The housing is provided with an opening communicating with the interior of the drum assembly 20, and the door is used to open or close the opening. The door seal 30 is used to seal the gap between the drum assembly 20 and the opening of the housing. When the door closes the opening, the door seals against the door seal 30 in a sealing manner. Thus, the interconnected space formed by the door, the door seal 30, and the interior of the drum assembly 20 constitutes a laundry processing chamber.
[0114] The door seal 30 has an installation opening, and the water outlet end of the detergent dispensing device 10 passes through the installation opening of the door seal 30 and extends to the radial inner side of the door seal 30. This is conducive to the water outlet end of the detergent dispensing device 10 to dispense the detergent mixed solution into the clothing processing chamber.
