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

[0002] Taking the application of dispensing components in clothing processing equipment as an example, in some related technologies, the water flow inside the lid dissolves the detergent injected into the lid to form a detergent mixture, which is then sprayed onto the clothing in the clothing 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, embodiments of this application aim to provide a dispensing component, a detergent dispensing device, and a clothing treatment equipment that helps to balance the inlet water pressure in the mixing zone.

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

[0005] A water circuit board has a first water flow channel and a first water inlet. The first water flow channel includes an inlet water path, a mixing zone, and a pressure relief water path. The inlet water path connects the first water inlet and the mixing zone. The wall of the mixing zone is provided with a detergent inlet. The mixing zone is used to mix water and detergent to obtain a detergent mixture.

[0006] One end of the pressure relief water passage is connected to the water inlet water passage and is used to relieve pressure in the water inlet water passage;

[0007] The path from the connection point between the inlet water path and the pressure relief water path to the mixing zone is a tortuous path.

[0008] In some implementations, the water inlet path includes a meandering section that bends in the opposite direction multiple times in the horizontal plane, and the connection point between the water inlet path and the pressure relief path is located upstream of the meandering section.

[0009] In some implementations, the first water inlet is located at one end of the water channel plate along a first direction, the water channel plate includes a partition wall, and the first water inlet and the mixing zone are respectively located on opposite sides of the partition wall along a second direction, wherein the first direction is perpendicular to the second direction.

[0010] In some implementations, the meandering section includes multiple sub-waterways, each of which extends generally along a first direction, the multiple sub-waterways are arranged along a second direction, and the inlet and outlet ends of each of the sub-waterways are staggered, wherein the first direction is perpendicular to the second direction.

[0011] In some embodiments, the water channel plate includes a plurality of first ribs, each of which extends along a first direction, and the plurality of first ribs are arranged at intervals along a second direction, with the sub-water channel being formed between two adjacent first ribs;

[0012] The first rib has a notch for fluid to pass through, and the notches of two adjacent first ribs are staggered.

[0013] In some embodiments, the water channel plate includes at least two second ribs, each of which bends in the opposite direction multiple times in the horizontal plane and extends continuously, with at least a portion of the meandering section enclosed between two adjacent second ribs.

[0014] In some embodiments, the water circuit board includes a bridge plate, the bridge plate being provided with a pressure relief hole, the pressure relief hole penetrating the bridge plate along the height direction, and liquid from the water inlet circuit entering the pressure relief circuit through the pressure relief hole.

[0015] In some implementations, in a horizontal projection, the projection of the bridge plate is within the projection of the pressure relief water passage, and the projection of the bridge plate is outside the projection of the water inlet water passage.

[0016] In some implementations, the water circuit board has an outlet for connecting to a pipeline, and the first water flow channel includes an outlet water path that connects the mixing zone and the outlet water path.

[0017] In some implementations, the projections of the inlet water path on the horizontal plane and the projections of the outlet water path on the horizontal plane intersect, but are not connected at the point of intersection.

[0018] In some implementations, the delivery component includes a flow-blocking component disposed in the pressure relief water passage, with at least one end of the flow-blocking component connected to the wall of the pressure relief water passage and the other end extending obliquely upstream in the direction of fluid flow.

[0019] This application embodiment also provides a detergent dispensing device, including:

[0020] Dispenser box for holding detergent;

[0021] And the dispensing component described in any embodiment of this application, wherein the dispenser box is located below the water channel plate, and the dispenser box is capable of being pulled out relative to the dispensing component;

[0022] A liquid pump is used to draw detergent from the dispenser box and pump it to the mixing zone through the detergent inlet.

[0023] In some implementations, the bottom wall of the pressure relief water passage is provided with one or more drain holes, and the projection of the one or more drain holes on the horizontal plane is outside the projection of the distributor box.

[0024] In some embodiments, the detergent dispensing device includes a box body, and the water circuit board is disposed on the top side of the box body, together forming a receiving space for accommodating the dispenser box;

[0025] The box has a pull-out opening through which the dispenser box can be pulled out. In a horizontal projection, the projection of at least one of the drain holes is located on the side of the dispenser box away from the pull-out opening.

[0028] And the detergent dispensing device described in any embodiment of this application;

[0029] A nozzle and a spray pipe, wherein the spray pipe connects the nozzle and the water circuit board, and the nozzle is used to discharge liquid into the clothing treatment chamber.

[0030] The dispensing component provided in this application embodiment sets a tortuous path between the location where the inlet water path and the pressure relief water path connect to the mixing zone, so that the fluid flow path between the pressure relief location and the mixing zone undergoes multiple bypasses. On the one hand, this makes the flow path of the inlet water path from the location where the inlet water path and the pressure relief water path connect to the mixing zone as long as possible. The long flow path helps to slow down the flow velocity and pressure of the liquid flowing to the mixing zone, thereby balancing the inlet water pressure of the mixing zone. On the other hand, the tortuous path can effectively prevent the detergent mixture in the mixing zone from flowing back into the inlet water path, and minimize the possibility of the detergent mixture in the mixing zone flowing back to the pressure relief location and being discharged.

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.

[0045] The first aspect of this application provides a delivery component 1, please refer to... Figure 1 The delivery component 1 includes a water channel plate 10.

[0046] This application also provides a detergent dispensing device, which includes a dispenser box, a liquid pump 2, and a dispensing component 1 provided in any embodiment of this application.

[0047] For example, the dispenser box is located below the water channel plate 10, and the dispenser box is capable of being pulled out relative to the dispensing assembly 1. The liquid pump 2 is used to draw detergent from the dispenser box and pump it to the mixing zone 112 through the detergent inlet 1121. Thus, automatic detergent dispensing is achieved.

[0048] For example, the dispenser box includes a reservoir, and the pump 2 is used to draw detergent from the reservoir.

[0049] The dispenser box is used to hold detergent. Detergent can be laundry liquid, fabric softener, disinfectant, perfume, etc.

[0050] For example, the detergent dispensing device includes a box body 20, a water channel plate 10 is disposed on the top side of the box body 20, and the two sides together form a receiving space for accommodating the dispenser box.

[0051] For example, the container body 20 has a pull-out opening 22 through which the dispenser box can be pulled out. That is, the dispenser box is pulled out of the container body 20 and can be removed from the container body 20 through the pull-out opening 22. When the user needs to add detergent to the dispenser box, the dispenser box is pulled out from the pull-out opening 22. After the detergent is added, the dispenser box is pushed back into the container body 20.

[0052] In some embodiments, the housing 20 has a mixing groove 21 located below the dispenser housing. The mixing groove 21 is part of the receiving space.

[0053] For example, the mixing tank 21 has a liquid outlet 211 for discharging liquid from the mixing tank 21.

[0054] This application also provides a garment processing device.

[0055] The specific type of clothing processing equipment is not limited; for example, it can be a washing machine, a washer-dryer combo, etc.

[0056] The garment handling equipment 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. The drum assembly has a garment handling chamber for holding garments.

[0057] 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 a mixture of detergent and clean water provided simultaneously to wash the clothes and / or the drum assembly.

[0058] 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.

[0059] For example, the garment handling device includes a connecting pipe that connects the drum assembly and the outlet 211. Thus, detergent from the detergent dispensing device can be dispensed into the drum assembly through the outlet 211 and the connecting pipe.

[0060] In some embodiments, the water channel plate 10 has a first water flow channel 11 and a first water inlet, such as Figure 2 and Figure 4 As shown, the first water flow channel 11 includes a water inlet path 111 and a mixing zone 112. The water inlet path 111 connects the first water inlet and the mixing zone 112. The wall of the mixing zone 112 is provided with a detergent inlet 1121. The mixing zone 112 is used to mix water and detergent to obtain a detergent mixture. That is, the water inlet path 111 transports a portion of the liquid from the first water flow channel 11 to the mixing zone 112.

[0061] It should be noted that the arrows indicate the approximate direction of the liquid flow.

[0062] In some embodiments, the water circuit board 10 has an outlet 18 for connecting to a pipeline. The first water flow channel 11 includes an outlet water path 114, which connects the mixing zone 112 and the outlet 18. This allows the detergent mixture in the mixing zone 112 to flow through the outlet water path 114 to the outlet 18, and then through the outlet 18 to the pipeline.

[0063] The type of pipeline is not limited; for example, it can be a spray pipe 5.

[0064] It should be noted that the first water flow channel 11 is connected to an external water source through the first water inlet.

[0065] For example, the first water flow channel 11 includes a pressure relief water passage 113, one end of which is connected to the inlet water passage 111 for relieving pressure on the inlet water passage 111. In this way, the pressure relief water passage 113 can relieve pressure on the liquid in the inlet water passage 111 that has not yet been mixed with detergent, which helps to balance the inlet water pressure of the mixing zone 112.

[0066] For example, the dispensing component 1 includes a cover plate 16, and the water channel plate 10 includes a plate body 14 and a plurality of ribs 15. The plurality of ribs 15 (i.e., all the ribs 15) form openings in the surface of the plate body 14. The cover plate 16 is disposed on the side of the water channel plate 10 where the ribs 15 are disposed and closes the openings of the openings in the slots, thereby enclosing and forming at least one water flow channel, such as a first water flow channel 11. In this way, the fluid can flow along a predetermined path under the constraint of the ribs 15 and the cover plate, thereby reducing the possibility of crossflow between adjacent water flow channels and improving the stability of the fluid flow within the water flow channel.

[0067] In some implementations, the path from the connection point between the inlet water passage 111 and the pressure relief water passage 113 (hereinafter referred to as the pressure relief point) to the mixing zone 112 is a tortuous path.

[0068] It should be noted that the tortuous path can be a straight line with multiple bends, a curved line with multiple bends, or a combination of straight lines and curves. In other words, the fluid flow path from the pressure relief position to the mixing zone 112 is not a straight line.

[0069] In some related technologies, the connection between the inlet water passage and the pressure relief water passage is located on the side wall of the mixing zone. During the pressure relief process, a portion of the detergent mixture in the mixing zone will flow from the pressure relief location to the pressure relief water passage, thus wasting some detergent.

[0070] In this embodiment, the dispensing component 1 is configured as a tortuous path between the pressure relief position and the mixing zone 112, causing the fluid flow path between the pressure relief position and the mixing zone 112 to bypass multiple times. On the one hand, this makes the flow path of the inlet water channel 111 from the pressure relief position to the mixing zone 112 as long as possible. The long flow path helps to slow down the flow rate and pressure of the liquid flowing to the mixing zone 112, thereby balancing the inlet water pressure of the mixing zone 112. On the other hand, the tortuous path can effectively prevent the detergent mixture in the mixing zone 112 from flowing back to the inlet water channel 111, and minimize the possibility of the detergent mixture in the mixing zone 112 flowing back to the pressure relief position and being discharged.

[0071] In some embodiments, please refer to the following simultaneously: Figure 2 and Figure 3 The first water inlet 10a is located at one end of the waterway 10 along the first direction. The waterway plate 10 includes a partition wall 19. The first water inlet 10a and the mixing zone 112 are respectively located on opposite sides of the partition wall 19 along the second direction, wherein the first direction is perpendicular to the second direction.

[0072] The first inlet 10a and the mixing zone 112 are located on opposite sides of the partition wall 19 along the second direction, that is, a portion of the inlet water passage 111 and the mixing zone 12 are located on opposite sides of the partition wall 19 along the second direction.

[0073] It should be noted that the partition wall 19 is impermeable, meaning that the water inlet channel 111 and the mixing zone 112 are not connected at the partition wall.

[0074] In this way, the fluid entering the water inlet 111 from the first inlet 10a has to take a tortuous path to reach the mixing zone 112, and the detergent mixture in the mixing zone 112 cannot flow to the water inlet 111 through the partition wall 19, thereby further reducing the probability that the detergent mixture in the mixing zone 112 will flow back to the pressure relief position and be discharged.

[0075] For example, the first direction is Figure 2 and Figure 4 The direction indicated by v1 is the second direction. Figure 2 and Figure 4 The direction indicated by v2 in the middle.

[0076] In some embodiments, the water inlet path 111 includes a meandering section 1111, which bends in opposite directions multiple times in the horizontal plane, and the pressure relief point of the water inlet path 111 is located upstream of the meandering section 1111. Thus, the path of the meandering section 1111 forms part of a tortuous path. The meandering section 1111 helps reduce the liquid flow velocity, allowing the liquid to enter the mixing zone 112 at a relatively low flow rate to mix with the detergent, which helps increase the mixing time between the liquid and the detergent and improves the detergent's dissolution effect. Furthermore, the detergent mixture in the mixing zone 112 is less likely to flow back upstream of the meandering section 1111 due to the obstruction of the meandering section 1111, thus ensuring that almost all of the detergent mixture flows downstream of the mixing zone 112.

[0077] It should be noted that the horizontal plane refers to the plane perpendicular to the height direction.

[0078] It is understandable that the formation of the detour segment 1111 is not limited.

[0079] For example, in some embodiments, such as Figure 3 As shown, the meandering section 1111 includes multiple sub-waterways 1111a. Each sub-waterway 1111a extends approximately along a first direction, and the multiple sub-waterways 1111a are arranged along a second direction. The inlet and outlet ends of each sub-waterway 1111a are staggered.

[0080] It should be noted that a single sub-waterway 1111a extends approximately along the first direction. This can be that the single sub-waterway 1111a is a straight line along the first direction, or the single sub-waterway 1111a is a straight line with a certain angle to the first direction, or the single sub-waterway 1111a has a partial bend, but the direction of the line connecting the beginning and end of the single sub-waterway 1111a is along the first direction.

[0081] It should be noted that the staggered arrangement of individual sub-water channels 1111a means that the line connecting the inlet and outlet of an individual sub-water channel 1111a is not parallel to the second direction. In other words, after the fluid enters from the inlet of an individual sub-water channel 1111a, it will not immediately flow out from the outlet, but will flow out from the outlet after passing through a path that extends roughly along the first direction.

[0082] Thus, after the fluid enters from the inlet of the detour section 1111, it needs to continuously flow around the multiple sub-channels 1111a arranged along the second direction, which helps to increase the flow path of the fluid in the detour section 1111.

[0083] For example, such as Figure 3As shown, the water channel plate 10 includes a plurality of first ribs 151, that is, a portion of the plurality of ribs 15 are first ribs 151. A single first rib 151 extends along a first direction, and the plurality of first ribs 151 are arranged at intervals along a second direction. A sub-water channel 1111a is formed between two adjacent first ribs 151. The first ribs 151 are provided with notches 151a for fluid to pass through, and the notches of two adjacent first ribs 151a are staggered.

[0084] The notches of two adjacent first ribs 151 are staggered, meaning that the line connecting the notches of two adjacent first ribs 151 is not parallel to the second direction. That is, the notch 151a of one of the first ribs 151 serves as the inlet end of the sub-water passage 1111a enclosed by the two first ribs 151, and the notch 151a of the other first rib 151 serves as the outlet end of the sub-water passage 1111a enclosed by the two first ribs 151. In this way, the inlet and outlet ends of a single sub-water passage 1111a are staggered.

[0085] In this embodiment, the single sub-waterway 1111a enclosed by two adjacent first ribs 151 can extend along the first direction, and multiple sub-waterways 1111a are arranged along the second direction. The structure between two adjacent sub-waterways 1111a is relatively compact, and the flow path of the fluid through multiple sub-waterways 1111a is as long as possible.

[0086] In some embodiments, the water channel plate 10 includes at least two second stiffeners, that is, a portion of the multiple stiffeners 15 are second stiffeners. A single second stiffener bends in the opposite direction multiple times in the horizontal plane and extends continuously, forming at least a partial meandering section 1111 between two adjacent second stiffeners.

[0087] It should be noted that the multiple reverse bending and continuous extension of a single second rib in the horizontal plane means that the projection of a single second rib in the horizontal plane is a continuously extending line. Continuous extension means that the projection curve of a single second rib in the horizontal plane will not break at any position.

[0088] In this embodiment, the length of the fluid flow path in the detour section 1111 can be controlled by controlling the degree and number of bends of the second rib. Multiple reverse bends help to increase the fluid flow path in the detour section 1111.

[0089] In some embodiments, the water circuit board 10 includes a bridge plate 13, which is provided with a pressure relief hole 131. The pressure relief hole 131 extends through the bridge plate 13 along the height direction, and liquid from the inlet water passage 111 enters the pressure relief water passage 113 through the pressure relief hole 131. This facilitates the inspection of the cross-sectional dimensions of the pressure relief hole 131 along the height direction to determine whether the cross-sectional dimensions of the pressure relief hole 131 meet manufacturing requirements, thereby helping to determine whether the inlet water pressure of the mixing zone 112 meets manufacturing requirements. That is, it helps improve the inspection efficiency during the manufacturing process, thereby also contributing to improved manufacturing efficiency.

[0090] In some embodiments, in a horizontal projection, the projection of the bridge plate 13 is located within the projection of the pressure relief water passage 113, and the projection of the bridge plate 13 is located outside the projection of the water inlet passage 111. In this way, the bridge plate 13 will not affect the flow of liquid in the water inlet passage 111, that is, it will not affect the water inlet efficiency of the water inlet passage 111.

[0091] In some embodiments, the projection of the inlet water passage 111 onto the horizontal plane and the projection of the outlet water passage 114 onto the horizontal plane intersect, and are not connected at the point of intersection.

[0092] It should be noted that "not connected" means that the liquid in the inlet water passage 111 must pass through the mixing zone 112 before flowing to the outlet water passage 114. The liquid in the inlet water passage 111 will not flow directly to the outlet water passage 114 at the projection intersection. Similarly, when the liquid flows to the outlet water passage 114, it will not flow back to the inlet water passage 111 at the projection intersection. When the liquid flows through the outlet water passage 114, it is located in the area above or below the inlet water passage 111.

[0093] The projections of the inlet water passage 111 and the outlet water passage 114 on the horizontal plane intersect to form a three-dimensional intersection structure, similar to an overpass design. The liquid in the inlet water passage 111 and the liquid in the outlet water passage 114 will not merge at the intersection of their projections, reducing interference or mixing of liquids from 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 needs and increase the versatility of the dispensing component 1.

[0094] In some embodiments, the delivery component 1 includes a flow-blocking component 17 disposed in the pressure relief water passage 113. At least one end of the flow-blocking component 17 (hereinafter referred to as the first end 171) is connected to the wall of the pressure relief water passage 113, and the other end (hereinafter referred to as the second end 172) extends obliquely upstream in the direction of fluid flow.

[0095] In some embodiments, please refer to Figure 4 and Figure 5The detergent dispensing device includes a flow-blocking component 17 disposed in the pressure relief water passage 113. At least one end of the flow-blocking component 17 is connected to the wall of the pressure relief water passage 113, and the other end extends obliquely upstream in the direction of fluid flow.

[0096] Understandably, the first end 171 of the flow-blocking assembly 17 is connected to the wall, and fluid cannot flow through the connection between the flow-blocking assembly 17 and the corresponding wall (i.e., the wall connected to the first end 171). The wall can support and fix the flow-blocking assembly 5 to ensure the stability of the flow-blocking assembly 17 in the pressure relief water channel 113.

[0097] Please refer to Figure 5 The second end 172 of the flow-blocking assembly 17 extends obliquely upstream in the direction of fluid flow. It can be understood that a channel that gradually widens in the direction of flow (this channel is part of the pressure relief water passage 113) is generally formed between the flow-blocking assembly 17 and another wall. When the fluid flows through this channel, the flow velocity can be reduced. Furthermore, due to the obstruction effect of the flow-blocking assembly 17, some fluid flows in the opposite direction for a short distance. During this process, the reverse-flowing fluid impacts the forward-flowing fluid, which also helps to reduce the flow velocity.

[0098] In some embodiments, the bottom wall of the pressure relief water passage 113 is provided with one or more drain holes. The drain holes are used to drain the liquid in the pressure relief water passage 113 into the mixing tank 21. In this way, by providing drain holes, the liquid in the pressure relief water passage 113 can be drained, which helps to maintain the liquid pressure inside the cover.

[0099] For example, in the orthographic projection on the horizontal plane, the projection of one or more drain holes is located outside the projection of the dispenser box. In this way, the liquid discharged from the drain holes is prevented from contacting the dispenser box as much as possible. On the one hand, this prevents the water flowing down from the drain holes from seeping out of the dispenser box through the gap between the dispenser box and the pull-out opening 2222. On the other hand, it also prevents excessive liquid from adhering to the outer wall of the dispenser box when the user pulls the dispenser box out of the pull-out opening 22.

[0100] In some embodiments, in a horizontal projection, the projection of at least one of the drain holes is located on the side of the dispenser box away from the pull-out opening 22. This allows some of the liquid from the pressure relief water path 113 to fall from the drain hole 12, thus flushing the detergent residue on the inner wall of the mixing tank 21 and effectively rinsing the inner wall of the mixing tank 21.

[0101] For example, the plurality of drain holes include a first drain hole 1131 and a second drain hole 1132, which are arranged at intervals along the fluid flow direction of the pressure relief water passage 113, and the second drain hole 1132 is located upstream of the first drain hole 1131. This helps to achieve step-by-step pressure relief.

[0102] In some embodiments, at least one water flow channel formed by the water flow plate 10 further includes a second water flow channel 12, wherein the first water flow channel 11 and the second water flow channel 12 are not connected to each other.

[0103] It should be noted that the first water flow channel 11 and the second water flow channel 12 are not connected to each other. This means that the liquid path of the first water flow channel 11 and the liquid path of the second water flow channel 12 are independent of each other. They may intersect or overlap in physical space, but there will be no unnecessary mixing between the liquid in the first water flow channel 11 and the liquid in the second water flow channel 12.

[0104] It should be noted that the second water flow channel 12 is connected to an external water source.

[0105] In some embodiments, the first water flow channel 11 and the second water flow channel 12 do not work simultaneously; that is, the external water source does not supply water to the first water flow channel 11 and the second water flow channel 12 at the same time.

[0106] For example, the second water flow channel 12 includes a water outlet area 121, and the bottom wall of the water outlet area 121 is provided with at least one water outlet hole 1211, which is used to guide liquid to the dispenser box.

[0107] Specifically, the dispenser box includes a first tank for holding detergent. A water outlet 1211 directs the liquid into the first tank. Thus, the liquid sprayed from the water outlet 1211 flows into the first tank, flushing and dissolving the detergent to form a detergent mixture. This detergent mixture flows into a mixing tank 21 below the dispenser box, and then flows through the outlet 211 into the drum assembly of the garment processing equipment. In other words, before each wash, the user needs to add detergent to the first tank, and the amount added each time is sufficient for a single wash. This dispensing method can also be called manual dispensing.

[0108] It should be noted that the liquid storage chamber of the dispenser box is not connected to the first tank. That is, the detergent in the first tank and the detergent in the liquid storage chamber do not affect each other.

[0109] It is understood that the detergent dispensing device in the embodiments of this application may have both manual dispensing function and automatic dispensing function, or may have only one of the manual dispensing function and automatic dispensing function, and this is not limited here.

[0110] For example, the detergent dispensing device includes a flushing pipe 3, which connects the second water flow channel 12 and the inner cavity of the pump 2, for guiding liquid into the inner cavity of the pump 2 to clean it. This achieves cleaning of the inner cavity of the pump 2 and reduces the likelihood of bacterial growth.

[0111] Specifically, when the pump 2 draws in detergent, the detergent enters the inner cavity and is then pumped out. It is understood that the liquid in the flushing line 3 enters the inner cavity of the pump 2 in a unidirectional manner; that is, the liquid in the inner cavity of the pump 2 will not flow back into the flushing line 3.

[0112] In some embodiments, in the orthographic projection on the horizontal plane, the projection of the first water flow channel 11 and the projection of the second water flow channel 12 intersect and are not connected at the intersection; the first water flow channel 11 passes above or below the second water inlet passage at the intersection.

[0113] It should be noted that the first water flow channel 11 and the second water flow channel 12 intersect but are not interconnected at the intersection. The first water flow channel 11 passing above or below the second water inlet passage at the intersection means that the projections of the first water flow channel 11 and the second water flow channel 12 on the horizontal plane overlap. At least a portion of the first water flow channel 11 and at least a portion of the second water flow channel 12 are arranged along the height direction, and the first water flow channel 11 and the second water flow channel 12 share a common portion that separates them. This ensures that the first water flow channel 11 and the second water flow channel 12 are not interconnected at the intersection. That is, when liquid flows through the first water flow channel 11, it will not flow to the second water flow channel 12 through the intersection, or vice versa. When liquid flows through the first water flow channel 11, it is located in the area above or below the second water flow channel 12.

[0114] This design creates a three-dimensional intersection structure at the point where the first water flow channel 11 and the second water flow channel 12 intersect, similar to an overpass design. The liquid in the first water flow channel 11 and the liquid in the second water flow channel 12 will not merge at their intersection, reducing interference or mixing between liquids flowing in different directions and improving flow reliability and stability. In other words, the flow paths of manually dispensed liquid and automatically dispensed liquid will not interfere with each other. Simultaneously, it facilitates flexible layout of the water flow channels within a limited space to meet different usage requirements, increasing the versatility of the dispensing component 1.

[0115] In some embodiments, the garment processing device includes a spray pipe 5 and a nozzle, the spray pipe 5 connecting the nozzle and a water distribution plate. The nozzle is used to dispense liquid into the garment processing chamber.

[0116] Specifically, one end of the spray pipe 5 is connected to the water outlet 18.

[0117] In this way, the nozzle can directly spray the detergent mixture onto the clothes inside the garment processing chamber, which is beneficial for the detergent components to come into contact with the surface of the clothes and improve the washing ratio.

[0118] For example, the garment handling device includes a door seal ring located at the front end of the cylinder assembly, and a nozzle located at the door seal ring. This facilitates the nozzle discharging liquid towards the interior of the garment handling chamber.
