Abstract

This application provides a dispensing component, a detergent dispensing device, and a clothing treatment equipment. The dispensing component includes a water circuit board with a first water flow channel. The first water flow channel includes an inlet water channel, a bridge plate, a pressure relief water channel, and a pressure relief hole. The pressure relief hole penetrates the bridge plate along the height direction. The pressure relief water channel is connected to the first inlet water channel through the pressure relief hole, and the pressure relief water channel is used to relieve pressure in the inlet water channel. The dispensing component provided by this application relieves pressure in the inlet water channel through the pressure relief water channel, resulting in a more stable water pressure in the inlet water channel after pressure relief. Because the pressure relief hole penetrates the bridge plate along the height direction, during the manufacturing process, after the pressure relief hole is machined, measuring tools can directly measure the diameter and cross-sectional area of ​​the pressure relief hole from top to bottom without being obstructed by other structures on the water circuit board. Pressure relief holes that do not meet the design requirements are rejected, thereby effectively ensuring the accuracy of the pressure relief hole and ensuring the pressure stability of the inlet water channel.

Description

Technical Field

[0001] This application relates to the field of clothing processing technology, and in particular to a dispensing component, a detergent dispensing device, and clothing processing equipment. Background Technology

[0002] In related technologies, taking the application of a dispensing component in clothing processing equipment as an example, the water flow inside the lid dissolves the detergent injected into the lid to form a detergent mixture. This detergent mixture is then sprayed onto the clothing in the processing chamber through pipes and nozzles. The water inlet pressure affects the spraying effect. Therefore, it is necessary to balance the water inlet pressure of the dispensing component. Utility Model Content

[0003] In view of this, the embodiments of this application aim to provide a dispensing component, a detergent dispensing device, and a clothing treatment equipment that can effectively balance the water inlet pressure of the dispensing component.

[0004] This application provides a delivery component, including:

[0005] A water circuit board has a first water flow channel, which includes an inlet water channel, a bridge plate, a pressure relief water channel, and a pressure relief hole. The pressure relief hole penetrates the bridge plate along the height direction. The pressure relief water channel is connected to the first inlet water channel through the pressure relief hole. The pressure relief water channel is used to relieve pressure on the inlet water channel.

[0006] In some implementations, the first water flow channel includes a mixing zone, the water circuit board is provided with a first water inlet and a detergent inlet, the detergent inlet is provided on the wall of the mixing zone so that the detergent and liquid are mixed in the mixing zone to form a detergent mixture, and the water inlet is connected to the first water inlet and the mixing zone.

[0007] In some implementations, the water inlet path includes a meandering section, which bends in opposite directions multiple times in the horizontal plane to form a serpentine winding structure, and the pressure relief point of the water inlet path is located upstream of the meandering section.

[0008] In some implementations, the water circuit board has a first water outlet for connecting to a pipeline, and the first water flow channel includes a water outlet path that connects the mixing zone and the first water outlet.

[0009] In some implementations, the orthographic projections of the inlet water path and the outlet water path on the horizontal plane intersect, but are not connected at the point of intersection.

[0010] In some implementations, the bridge plate is located in the pressure relief water passage in the orthographic projection onto the horizontal plane.

[0011] In some embodiments, the water channel plate includes: a plate body, a first rib and a second rib, the first rib and the second rib forming the pressure relief water channel on the surface of the plate body, and the bridge piece being located between the first rib and the second rib;

[0012] The space between the bridge piece and the plate forms a bridge hole, which is connected to the water inlet channel.

[0013] In some implementations, the water inlet channel and the pressure relief channel are located on opposite sides of the first rib, the first rib has a notch, and the bridge hole connects the notch and the pressure relief hole.

[0014] In some implementations, the plate, the first rib, the second rib, and the bridge piece are an integral structure.

[0015] In some implementations, the dispensing component includes at least one baffle plate, one end of which is connected to the wall of the pressure relief water passage, and the other end extends obliquely upstream in the direction of fluid flow.

[0016] In some implementations, the bottom wall of the pressure relief water passage is provided with at least one drain hole, which is used to guide the liquid in the pressure relief water passage to the bottom of the water passage plate.

[0017] This application embodiment also provides a garment processing device, including:

[0018] Cylinder assembly;

[0019] And the detergent dispensing device described in any embodiment of this application, wherein the detergent dispensing device is used to supply liquid to the drum assembly.

[0020] The dispensing component provided in this embodiment divides the liquid entering the inlet water path into two streams: one flows to the pressure relief water path, and the other flows downstream of the inlet water path. It should be noted that the water flow channels on the water circuit board are relatively narrow and intersecting. The water pressure entering the inlet water path from the first inlet may be relatively high or unstable. The pressure relief water path relieves pressure in the inlet water path, resulting in a more stable water pressure. Furthermore, since the pressure relief hole penetrates the bridge plate along the height direction (i.e., the pressure relief hole faces the height direction), during manufacturing, after the pressure relief hole is machined, measuring tools can directly measure the diameter and cross-sectional area of ​​the pressure relief hole from top to bottom without being obstructed by other structures on the water circuit board. Pressure relief holes that do not meet design requirements are discarded, thus effectively ensuring the accuracy of the pressure relief hole and guaranteeing the pressure stability of the inlet water path.

For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0031] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0032] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0033] Please see Figure 1 This application provides a dispensing component 10, which includes a water channel plate 101 (see reference 101). Figure 2 ).

[0034] This application also provides a detergent dispensing device, including a dispenser box and a dispensing component 10 according to any embodiment of this application. The dispenser box is used to hold detergent. The dispenser box can be pulled out relative to the water channel plate 101.

[0035] For example, the distributor box is located below the water pipe panel 101.

[0036] For example, the dispenser box has a first slot for holding detergent. The detergent may be laundry liquid, fabric softener, disinfectant, perfume, etc.

[0037] In some embodiments, please refer to Figure 1 and Figure 6 The detergent dispensing device includes a box body 20, a water circuit plate 101 disposed above the box body 20, the two together forming a receiving space and a pull-out opening 22, a dispenser box disposed in the receiving space, and the dispenser box is pushed into or pulled out of the receiving space through the pull-out opening 22.

[0038] When the user needs to add detergent to the first tank, at least part of the dispenser box can be pulled out from the receiving space through the pull-out 22, detergent can be added to the first tank, and then the dispenser box can be pushed back into the receiving space.

[0039] For example, before each wash, the user can add detergent to the first tub, with each addition providing the required amount for that single wash. This method of adding detergent can also be called manual addition.

[0040] Of course, in some embodiments, please refer to Figures 2 to 4 The detergent dispensing device may also include a pump 2. The dispenser box has a storage chamber for storing detergent. The pump 2 is used to extract detergent from the storage chamber. The storage chamber is not connected to the first tank, meaning that the detergent in the first tank and the detergent in the storage chamber do not affect each other. In this way, the pump 2 can be used to quantitatively extract detergent from the storage chamber to achieve automatic detergent dispensing.

[0041] Thus, the detergent dispensing device of this application embodiment can have both automatic and manual dispensing functions.

[0042] This application also provides a garment processing device. The garment processing device includes a drum assembly and a detergent dispensing device according to any embodiment of this application, the detergent dispensing device being used to supply liquid to the drum assembly.

[0043] The specific type of clothing processing equipment is not limited; for example, it can be a washing machine, a washer-dryer combo, etc.

[0044] It should be noted that the liquid supplied by the detergent dispensing device to the drum assembly can be a detergent mixture, clean water, or both detergent mixture and clean water can be supplied simultaneously to wash clothes and / or the drum assembly. Of course, the detergent dispensing device can also supply functional substances other than detergent mixture to the drum assembly to enhance the washing and care effect.

[0045] Functional substances can be metal ions such as silver ions and complex cations, which help improve the antibacterial effect of clothing; functional substances can also be herbal extracts such as peony root extract and plant active factors, which help improve the antibacterial effect; functional substances can also be water purification substances such as dynamic scale inhibitors and water softening ingredients, which can adsorb calcium and magnesium ions in liquids, reduce scale formation, help reduce the chance of hard water damaging clothing fibers, and also help reduce the chance of scale clogging water pipes; functional substances can also be slow-release cleaning and protective factors and antioxidants, which help reduce the chance of clothing fiber damage and delay clothing fading and aging.

[0046] The specific structure of the cylindrical assembly is not limited. Exemplarily, the cylindrical assembly includes an outer tub and an inner tub, with the inner tub rotatably disposed inside the outer tub. That is, the outer tub is fitted over the inner tub. The outer tub is used to hold water, and the inner tub is used to hold clothing. In this embodiment, the inner tub holds water through the outer tub, and the inner tub can also be referred to as a perforated inner tub.

[0047] The water circuit board 101 includes a first water flow channel 10d, which includes an inlet water channel 10d1, a pressure relief water channel 10e, a pressure relief hole 10g, and a bridge plate 103. The pressure relief water channel 10e and the inlet water channel 10d1 are connected through the pressure relief hole 10g. The pressure relief water channel 10e is used to relieve pressure on the inlet water channel 10d1. That is, the liquid entering the inlet water channel 10d1 is divided into two streams: one flows to the pressure relief water channel 10e, and the other flows to the pressure relief position of the inlet water channel 10d1. Figure 4 Downstream of position A shown in the diagram. It should be noted that the flow rate downstream of the pressure relief position is significantly greater than the flow rate of liquid flowing into the pressure relief water passage 10e. It should also be noted that the water flow channels on the water passage plate 101 are relatively narrow and intersecting. The water source (e.g., tap water) entering the inlet water passage 10d1 from the first inlet 1b may have a relatively high pressure or unstable water pressure. The pressure relief water passage 10e is used to relieve pressure on the inlet water passage 10d1, and the water pressure of the liquid in the inlet water passage 10d1 is relatively stable after pressure relief.

[0048] In some embodiments, please refer to Figure 5 The water channel plate 101 has a bridge piece 103, and the pressure relief hole 10g penetrates the bridge piece 103 along the height direction.

[0049] After the liquid in the inlet water passage 10d1 is depressurized from above or below the bridge plate 103 through the pressure relief hole 10g, it flows to the pressure relief water passage 10e. That is, the pressure relief water passage 10e achieves the function of diverting and depressurizing the inlet water passage 10d1 through the pressure relief hole 10g, so that the pressure of the inlet water passage 10d1 is maintained within a reasonable range.

[0050] Since the pressure relief hole 10g penetrates the bridge piece 103 along the height direction, meaning the pressure relief hole 10g faces the height direction, during the manufacturing process, after the pressure relief hole 10g is machined, measuring tools can directly measure the diameter and cross-sectional area of ​​the pressure relief hole 10g from top to bottom without being obstructed by other structures of the water circuit plate 101. Any pressure relief hole 10g that does not meet the design requirements will be rejected, thus effectively ensuring the accuracy of the pressure relief hole 10g and guaranteeing the pressure stability of the inlet water circuit 10d1.

[0051] In some embodiments, please refer to Figures 2 to 4 In the orthographic projection on the horizontal plane, bridge plate 103 is located in the pressure relief water channel 10e.

[0052] In other words, the projection of the bridge piece 103 is located within the area of ​​the pressure relief water passage 10e, and the bridge piece 103 can protrude from the bottom wall surface of the pressure relief water passage 10e.

[0053] In this embodiment, the orthographic projection of the bridge plate 103 on the horizontal plane is located in the pressure relief water channel 10e, which facilitates the pressure relief hole 10g to guide all the depressurized fluid to the pressure relief water channel 10e, reducing the probability of backflow and increasing the reliability of pressure relief.

[0054] In some embodiments, the first water flow channel 10d includes a mixing zone 10d3. The water circuit board 101 is provided with a first water inlet 1b and a detergent inlet 1a. The detergent inlet 1a is disposed on the wall of the mixing zone 10d3 so that the detergent and liquid are mixed in the mixing zone 10d3 to form a detergent mixture. The water inlet channel 10d1 connects the mixing zone 10d3 and the first water inlet 1b.

[0055] Liquid (e.g., tap water) enters the water inlet channel 10d1 from the first water inlet 1b. The water inlet channel 10d1 directs the water to the mixing zone 10d3. Detergent enters the mixing zone 10d3 from the detergent inlet 1a. The liquid and detergent mix in the mixing zone 10d3 to form a detergent mixture. In other words, in this embodiment, the mixing of detergent and liquid is achieved in the water circuit board 101.

[0056] In some embodiments, the water circuit board 101 has a first outlet 1c. The first outlet 1c is used to connect to the pipe 3. The first water flow channel 10d includes an outlet water path 10d2, which connects the mixing zone 10d3 and the first outlet 1c.

[0057] Water outlet 10d2 directs the detergent mixture to the first outlet 1c, which in turn directs it to pipe 3. Pipe 3 then sprays the detergent mixture into the garment processing chamber via a nozzle at its end. It should be noted that since the first outlet 1c is connected to pipe 3, and the spray force of the nozzle at the end of pipe 3 depends on the pressure of water outlet 10d2, the pressure stability of water outlet 10d2 must be ensured. Liquid from water inlet 10d1 enters water outlet 10e through pressure relief hole 10g. The pressure relief flow rate depends on the area of ​​pressure relief hole 10g. Therefore, by using a design where pressure relief hole 10g passes through bridge plate 103 along its height, the size of pressure relief hole 10g can be effectively controlled, thereby controlling the pressure relief flow rate and ultimately achieving water pressure control of water inlet 10d1.

[0058] In some embodiments, the inlet water passage 10d1 includes a meandering section 10d4, which bends repeatedly in opposite directions on the horizontal plane to form a serpentine winding structure. The pressure relief point of the inlet water passage 10d1 is located upstream of the meandering section 10d4. Please refer to [link to relevant documentation]. Figure 4 , Figure 4 The dashed box in the diagram shows the water flow path, with the meandering section 10d4.

[0059] The detour section 10d4 helps to reduce the liquid flow rate, allowing the liquid to enter the mixing zone 10d3 at a relatively low flow rate to mix with the detergent. This increases the mixing time between the liquid and the detergent, improving the detergent's dissolution effect. In addition, the detergent mixture in the mixing zone 10d3 is less likely to flow back upstream of the detour section 10d4 due to the obstruction of the detour section 10d4. Thus, it is beneficial for almost all of the detergent mixture to flow to the outlet water path 10d2.

[0060] Furthermore, the detour section 10d4 helps to extend the liquid flow path within the limited planar space of the water channel plate 101, thereby increasing the flow path between the mixing zone 10d3 and the first inlet 1b. This helps to further reduce the probability of the detergent mixture in the mixing zone 10d3 flowing back to the first inlet 1b.

[0061] In some embodiments, please refer to Figure 5 The orthographic projection of the inlet water channel 10d1 on the horizontal plane and the orthographic projection of the outlet water channel 10d2 on the horizontal plane intersect ( Figure 4 (as shown at point B in the diagram), and is not connected at the intersection of projections. The inlet water passage 10d1 passes above or below the outlet water passage 10d2.

[0062] In this embodiment, the projections of the inlet water passage 10d1 and the outlet water passage 10d2 on the horizontal plane overlap. The inlet water passage 10d1 and the outlet water passage 10d2 are staggered along the height direction at the intersection of their projections, similar to an overpass design. This ensures that the inlet water passage 10d1 and the outlet water passage 10d2 are not connected at the intersection of their projections. When the liquid flows through the inlet water passage 10d1, it flows through the area above or below the outlet water passage 10d2. That is, when the liquid flows through the inlet water passage 10d1, it will not flow into the outlet water passage 10d2 at the intersection of their projections, or the liquid will not flow into the inlet water passage 10d1 at the intersection of their projections.

[0063] The dispensing component 10 provided in this application embodiment has an inlet water channel 10d1 and an outlet water channel 10d2 whose projections intersect on a horizontal plane, forming a three-dimensional intersection structure at the projection intersection, similar to an overpass design. The liquid in the inlet water channel 10d1 and the liquid in the outlet water channel 10d2 will not merge at the projection intersection, reducing interference or mixing of liquids with different flow directions, improving flow reliability and stability. At the same time, it also facilitates flexible layout of the water flow channels in a limited space to meet different usage requirements and increase the versatility of the dispensing component 10.

[0064] In some embodiments, please refer to Figure 5The dispensing component 10 includes an arch bridge structure 1011, which is located in the space corresponding to the inlet water passage 10d1. The fluid in the outlet water passage 10d2 passes through the space below the arch bridge structure 1011, and the fluid in the inlet water passage 10d1 passes through the space above the arch bridge structure 1011.

[0065] In this embodiment, the arch bridge structure 1011 is located at the intersection of the projections of the inlet water passage 10d1 and the outlet water passage 10d2. The arch bridge structure 1011 separates the inlet water passage 10d1 and the outlet water passage 10d2. The bottom wall of the inlet water passage 10d1 can be formed on the top surface of the arch bridge structure 1011, and the top wall of the outlet water passage 10d2 can be formed on the bottom surface of the arch bridge structure 1011.

[0066] In this embodiment, the arch bridge structure 1011 creates a spatially layered, non-interfering layout between the inlet water passage 10d1 and the outlet water passage 10d2. The arch bridge structure 1011 acts as a physical barrier, improving the sealing between the liquids in the inlet water passage 10d1 and the outlet water passage 10d2, ensuring that while their projections intersect, the liquids do not affect each other. Furthermore, the arch bridge structure 1011 raises the bottom wall of the inlet water passage 10d1, and its relatively high position allows it to prevent backflow to some extent when the water flow stops.

[0067] In some embodiments, the pressure relief location of the inlet water passage 10d1 ( Figure 4 The location indicated by point A in the diagram is upstream of the detour section 10d4.

[0068] When the pressure relief position of the inlet water passage 10d1 is located upstream of the detour section 10d4, the detergent mixture in the mixing zone 10d3 is not easy to flow back to the pressure relief water passage 10e or the first inlet 1b due to the obstruction of the detour section 10d4.

[0069] In some embodiments, the pressure relief position A of the water inlet channel 10d1 is located downstream of the arch bridge structure 1011. That is, the liquid first flows through the arch bridge structure 1011 and then reaches the pressure relief position A. The liquid entering the water inlet channel 10d1 from the first water inlet 1b, when flowing through the arch bridge structure 1011, the arch bridge structure 1011 provides a certain degree of obstruction to the liquid, slowing down the liquid flow rate. This makes it easier for the liquid to fill the water flow channel after flowing through the arch bridge structure 1011, resulting in a better and more stable pressure relief effect.

[0070] For example, please refer to Figures 2 to 4The bottom wall of the pressure relief water passage 10e is provided with at least one drain hole 101a. The drain hole 101a communicates with the pressure relief water passage 10e. The liquid in the pressure relief water passage 10e is discharged through the drain hole 101a to the bottom of the water passage plate 101, for example, to the box body 20.

[0071] For example, there are two drain holes 101a, which are spaced apart along the direction of liquid flow, with one drain hole 101a located downstream of the other. This facilitates step-by-step pressure relief.

[0072] In some embodiments, the projection of the drain hole 101a is located outside the projection outline of the dispenser box when projected onto a plane perpendicular to the height direction of the dispensing component 10. This minimizes the contact between the liquid discharged from the drain hole 101a and the dispenser box. On the one hand, it prevents the water flowing from the drain hole 101a from seeping out through the gap between the dispenser box and the pull-out opening 22. On the other hand, it also prevents excessive liquid from adhering to the outer wall of the dispenser box when the user pulls it out of the pull-out opening 22.

[0073] In some embodiments, when projected onto a plane perpendicular to the height of the dispensing component 10, the projection of at least one drain hole 101a is located on the side of the dispenser box away from the pull-out opening 22. This allows some of the liquid from the drain channel to fall through the drain hole 101a, thus flushing and cleaning any detergent residue remaining on the inner wall of the dispenser box.

[0074] In some embodiments, please refer to Figure 1 The dispensing component 10 includes a top cover plate 102, and the water channel plate 101 includes a plate body 1012 and multiple ribs 1013. The multiple ribs 1013 form multiple opening slots on the top surface of the plate body 1012. The top cover plate 102 is disposed on the top side of the water channel plate 101 and closes the openings of the multiple opening slots to form at least one water flow channel. It is understood that the connection method between the top cover plate 102 and the water channel plate 101 is not limited. It can be a detachable connection or a non-detachable connection. For example, it can be ultrasonic welding, laser welding, screw connection, bonding, riveting, etc.

[0075] In some embodiments, the structure formed by the mating of the top cover 102 and the water channel plate 101 can also be referred to as a box cover.

[0076] In some embodiments, the water channel plate 101 is a one-piece molded structure. That is, the water channel plate 101 is manufactured in one piece, which simplifies the molding process, speeds up the molding process, and reduces assembly steps. For example, the water channel plate 101 is injection molded in one piece.

[0077] In some embodiments, the top cover 102 is a one-piece molded structure. That is, the top cover 102 is manufactured in one piece, which simplifies the molding process, speeds up the molding process, and reduces assembly steps. For example, the top cover 102 is injection molded in one piece.

[0078] For example, the water channel plate 101 and the top cover plate 102 are integrally formed and then connected along the height direction of the clothing processing equipment.

[0079] In some embodiments, the space between the bridge plate 103 and the plate 1012 forms a bridge hole, which is connected to the inlet water passage 10d1. That is, some of the liquid in the inlet water passage 10d1 can enter the bridge hole and then overflow from the pressure relief hole 10g above the bridge hole, and then enter the pressure relief water passage 10e. In this way, the liquid in the inlet water passage 10d1 will not impact the pressure relief hole 10g in the flow direction of the inlet water passage 10d1, so that the liquid in the inlet water passage 10d1 flows preferentially to the downstream of the inlet water passage 10d1.

[0080] In some embodiments, please refer to Figures 2 to 5 The dispensing component 10 includes a flow-blocking component 105, which is disposed in the pressure relief water passage 10e. At least one end of the flow-blocking component 105 is connected to the wall of the pressure relief water passage 10e, and the other end extends obliquely upstream in the direction of fluid flow.

[0081] The flow-blocking assembly 105 includes multiple flow-blocking plates.

[0082] The flow-blocking assembly 105 is used to block, guide, or regulate the flow of liquid.

[0083] One end of the flow-blocking component 105 is connected to the wall of the pressure relief water passage 10e, that is, the wall of the pressure relief water passage 10e can provide connection support for the flow-blocking component 105 to increase the flow-blocking stability.

[0084] The aforementioned flow-blocking component 105 extends obliquely upstream in the direction of fluid flow. In other words, the flow-blocking plate does not extend in the direction of fluid flow. When the liquid flows through the flow-blocking plate, the flow area changes from narrow to wide.

[0085] In this embodiment, when the liquid entering the pressure relief water path 10e passes through the flow blocking component 105, the flow blocking component 105 changes the flow direction of the liquid and slows down the flow rate by physically blocking it. In this way, the water flow velocity at the drain hole 101a can be reduced, thereby reducing the splashing degree of the liquid falling from the drain hole 101a.

[0086] The lengths of all the baffles can be all the same, all different, or partially the same, etc. There are no restrictions here.

[0087] In the description of this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the embodiments of this application. In this application, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Furthermore, without contradiction, those skilled in the art can combine different embodiments or examples described in this application, as well as features of different embodiments or examples.

[0088] The above description is merely a preferred embodiment of this application and is not intended to limit the application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
