Abstract
Description
Technical Field
[0001] This application relates to the field of electrical manufacturing technology, and in particular to a dispensing box assembly and clothing processing equipment. Background Technology
[0002] Existing washing machine detergent dispensers are primarily used to store detergents, fabric softeners, and other cleaning products, which are then dissolved and fed into the washing tub upon water intake. However, when the washing machine is in high-speed spin-drying or heavy-duty washing mode, a large amount of foam is generated inside the tub. This foam flows backward into the detergent dispenser through the connection channel between the dispenser and the tub, and some of it overflows from the gaps between the dispenser and the casing, resulting in a poor user experience. Utility Model Content
[0003] Based on this, embodiments of this application provide a dispensing box assembly and a clothing processing device.
[0004] In a first aspect, embodiments of this application provide a delivery box assembly, including:
[0005] A dispensing box, the dispensing box comprising a box body having a water outlet;
[0006] A flap, wherein the flap is disposed at the water outlet, the flap comprising a plate body, the plate body being rotatably connected to the box body;
[0007] In its natural state, the flap blocks the water outlet. When water enters the box, the flap can flip under water pressure to open the water outlet.
[0008] In some embodiments, the flap further includes a counterweight mounted on the plate, the center of gravity of the counterweight being located below the center of gravity of the plate.
[0009] In some embodiments, the plate is provided with a groove, and at least a portion of the counterweight is accommodated in the groove.
[0010] In some embodiments, the counterweight is spherical; and / or,
[0011] The inner wall of the groove is spherical.
[0012] In some embodiments, the material density of the counterweight is greater than the material density of the plate; and / or,
[0013] The plate is made of plastic; and / or,
[0014] The counterweight is made of metal.
[0015] In some embodiments, the plate body is provided with a plurality of protruding structures, and when the flip plate is in its natural state, the plurality of protruding structures are arranged facing outwards from the delivery box.
[0016] In some embodiments, the protruding structure is provided with a first through hole, and the plate is provided with a second through hole at a position corresponding to the first through hole, wherein the first through hole and the second through hole communicate with each other.
[0017] In some embodiments, the dispensing box further includes a connecting pipe, which is connected to the box body and communicates with the water outlet;
[0018] The dispensing box assembly also includes a water inlet pipe, which is connected to the connecting pipe.
[0019] In some embodiments, the dispensing box assembly further includes a first rotating shaft and a second rotating shaft, the first rotating shaft and the second rotating shaft being respectively disposed on both sides of the water outlet and both connected to the box body;
[0020] The plate has a first recess and a second recess on both sides, at least a portion of the first rotating shaft is accommodated in the first recess, and at least a portion of the second rotating shaft is accommodated in the second recess.
[0021] Secondly, embodiments of this application provide a garment processing device, including the dispensing box assembly described above.
[0022] The dispensing box assembly provided in this application embodiment has a flap at the water outlet of the dispensing box. Since the flap can block the water outlet in its natural state, when foam is generated in the washing tub, the foam cannot flow back into the dispensing box body through the water outlet. This avoids the problem of foam overflowing into the outside of the washing machine through the gap between the dispensing box and the box body. In addition, since the flap can be flipped under external force, when water enters the dispensing box body, the flap can be flipped under water pressure to open the water outlet, so that the water can flow smoothly into the washing machine tub through the water outlet, thus not affecting the water intake function of the dispensing box assembly.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0037] Please see Figure 1 , Figure 2 and Figure 5 This application provides a dispensing box assembly 100, including a dispensing box 20 and a flap 30. The dispensing box 20 includes a box body 21 with a water outlet 215. The flap 30 is disposed at the water outlet 215 and includes a plate body 31, which is rotatably connected to the box body 21. In its natural state, the flap 30 blocks the water outlet 215. When water enters the box body 21, the flap 30 can open the water outlet 215 under water pressure.
[0038] For example, the dispensing box 20 can be used to dispense detergents, fabric softeners, bleach, disinfectants and other cleaning products.
[0039] It should be noted that the natural state refers to the state when no external force is applied to the flap 30.
[0040] It is understandable that when the washing machine is in the off state, the flap 30 is in the natural state; when the washing machine is in the washing state (non-water inlet state), the flap 30 is in the natural state, and the lower side of the flap 30 is in contact with the lower edge of the water outlet 215 to achieve the purpose of sealing the water outlet 215.
[0041] It is understandable that when water enters the box 21, the static water can exert pressure on the flap 30, and the water flow entering the box 21 usually has a certain impact force, which can further enhance the pressure exerted by the water flow on the flap 30, thereby opening the flap 30 to allow water to enter the washing tub.
[0042] The dispensing box assembly 100 provided in this application embodiment has a flap 30 installed at the water outlet 215 of the dispensing box 20. Since the flap 30 can block the water outlet 215 in its natural state, when foam is generated in the washing tub, the foam cannot flow back into the box body 21 of the dispensing box 20 through the water outlet 215. This avoids the problem of foam overflowing to the outside of the washing machine through the gap between the dispensing box 20 and the box body 210. In addition, since the flap 30 can be flipped under external force, when water enters the box body 21 of the dispensing box 20, the flap 30 can be flipped under water pressure to open the water outlet 215, so that the water can flow smoothly into the washing machine tub through the water outlet 215, thereby not affecting the water intake function of the dispensing box assembly 100.
[0043] Please see Figure 5 The flip plate 30 also includes a counterweight 32 installed on the plate 31, and the center of gravity of the counterweight 32 is located below the center of gravity of the plate 31.
[0044] It is understandable that by setting a counterweight 32 on the plate 31 and making the center of gravity of the counterweight 32 located below the center of gravity of the plate 31, the center of gravity of the flap 30 can be lowered. Under the action of gravity, the plate 31 of the flap 30 can remain vertical, so that the lower side of the plate 31 of the flap 30 can keep in contact with the lower edge of the outlet 215, thereby achieving the effect of sealing the outlet 215.
[0045] For example, the geometric center of the counterweight 32 is located below the geometric center of the plate 31. It can be understood that for an object with a regular shape and uniform density, the geometric center is its center of gravity. That is to say, when the counterweight 32 has a regular shape and uniform density, the geometric center of the counterweight 32 is its center of gravity, and when the plate 31 has a regular shape and uniform density, the geometric center of the plate 31 is its center of gravity.
[0046] For example, the counterweight 32 and the plate 31 may or may not be connected. When the counterweight 32 and the plate 31 are not connected, the movement of the counterweight 32 can be restricted by spatial limiting, thereby enabling the counterweight 32 to be installed on the plate 31.
[0047] Please see Figure 5 The plate 31 is provided with a groove 305, and at least a portion of the counterweight 32 is accommodated in the groove 305.
[0048] Understandably, by providing a groove 305 on the plate 31 and allowing at least a portion of the counterweight 32 to be accommodated in the groove 305, the groove 305 can be used to limit the counterweight 32 and prevent the counterweight 32 from shaking or falling off.
[0049] Please see Figure 5 For example, the counterweight 32 is spherical, such as a sphere or an ellipsoid, and more than half of the volume of the counterweight 32 is accommodated in the groove 305, so that the groove 305 can limit the counterweight 32, and the counterweight 32 can be installed on the plate 31 without being connected to the plate 31.
[0050] Please see Figure 5 The inner wall of the groove 305 is spherical. In some embodiments, the inner wall of the groove 305 is a part of a spherical or elliptical surface.
[0051] For example, the material density of the counterweight 32 is greater than that of the plate 31.
[0052] For example, the material of the plate 31 is plastic.
[0053] For example, the material of the counterweight 32 is metal.
[0054] It is understandable that by setting the material density of the counterweight 32 to be greater than that of the plate 31, that is, the weight of the counterweight 32 is greater. After the counterweight 32 is fixed on the plate 31, the weight under the flap 30 increases. Under the action of gravity, the flap 30 can naturally be vertical, thus achieving a better sealing effect on the outlet 215.
[0055] For example, the plate 31 is provided with a plurality of protrusions 313, and when the flip plate 30 is in a natural state, the plurality of protrusions 313 are arranged facing the outside of the delivery box 20.
[0056] It should be noted that by setting multiple protrusions 313 on the plate 31, the protrusions 313 can be used to puncture the foam that moves from inside the washing tub to the outlet 215, thereby reducing the amount of foam entering the dispensing box 20 and further reducing the risk of foam overflowing from the dispensing box 20 to the outside of the washing machine.
[0057] For example, the protrusion structure 313 may be cylindrical, prismatic, frustum-shaped or prismatic.
[0058] In some embodiments, the protruding structure 313 is provided with a first through hole 301, and the plate 31 is provided with a second through hole at a position corresponding to the first through hole 301, wherein the first through hole 301 and the second through hole communicate with each other.
[0059] It is understandable that when the first through hole 301 on the protruding structure 313 is connected to the second through hole on the plate 31, it means that the flap 30 has a through hole structure composed of the first through hole 301 and the second through hole. The through hole structure forms a gas channel connecting the dispensing box 20 and the washing tub, so that it can play a role in venting when the pressure inside the washing tub is too high.
[0060] Please see Figure 3 and Figure 4 The dispensing box 20 further includes a connecting pipe 22, which is connected to the box body 21 and communicates with the water outlet 215; the dispensing box assembly 100 further includes a water inlet pipe 50, which is connected to the connecting pipe 22.
[0061] It is understood that the water inlet pipe 50 is used to connect to the water inlet of the washing tub to introduce the washing water in the dispensing box 20 into the washing tub.
[0062] For example, the water inlet pipe 50 is a corrugated pipe.
[0063] Please see Figure 2 The dispensing box assembly 100 further includes a first rotating shaft 41 and a second rotating shaft 42, which are respectively disposed on both sides of the water outlet 215 and are both connected to the box body 21.
[0064] The plate 31 has a first recess 311 and a second recess on both sides, at least a portion of the first rotating shaft 41 is accommodated in the first recess 311, and at least a portion of the second rotating shaft 42 is accommodated in the second recess.
[0065] It is understandable that by setting the first rotating shaft 41 and the second rotating shaft 42 to cooperate with the first recess 311 and the second recess on the flip plate 30 respectively, the rotational connection between the flip plate 30 and the dispensing box 20 can be realized.
[0066] For example, the outlet 215 can be circular or elliptical.
[0067] For example, the plate 31 can be circular or elliptical.
[0068] Please see Figure 6 This application embodiment also provides a clothing processing device 200, including the dispensing box assembly 100 as described above.
[0069] Please see Figure 6 The garment processing equipment 200 also includes a housing 210, and the dispensing box assembly 100 is installed on the housing 210.
[0070] For example, the clothing handling device 200 can be a washing machine or a washer-dryer combo, such as a front-loading washing machine, a front-loading washer-dryer combo, a top-loading washing machine, or a top-loading washer-dryer combo.
[0071] For example, the clothing processing device 200 also includes a washing tub, and the dispensing box assembly 100 is connected to the washing tub. Specifically, the end of the water inlet pipe 50 opposite to the connecting pipe 22 is connected to the water inlet of the washing tub.
[0072] The foregoing has provided a detailed description of the dispensing box assembly and clothing processing device provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application, and the descriptions of the embodiments above are merely for the purpose of helping to understand this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there may be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
