Description

Technical Field

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

[0002] In related technologies, since clothing processing equipment (such as washing machines) needs to add clothing processing agents (such as laundry detergent and fabric softener) during the washing process, most clothing processing equipment is equipped with a dispensing device to deliver the clothing processing agent into the clothing processing chamber.

[0003] Currently, most washing machines use a cavity structure in their detergent dispensing devices to mix detergent and water, aiming for thorough fusion. However, the cavity structure of existing dispensing devices is usually quite simple. After water and detergent enter, mixing is achieved solely through natural diffusion and the slight impact of water flow. This makes it difficult for the detergent to completely dissolve and disperse, easily leading to detergent agglomeration and locally excessively high concentrations. Ultimately, this results in uneven concentration of the detergent solution in the washing drum, affecting the washing effect on clothes. Utility Model Content

[0004] This application provides a dispensing device and a clothing treatment device that can fully mix the clothing treatment agent with water, improve the washing effect and reduce waste.

[0005] In a first aspect, embodiments of this application provide a dispensing device applied to a garment processing device, the dispensing device comprising: The inlet is used to input water. The treatment agent importer is used to import garment treatment agents; and Waterway, the waterway including: The meandering waterway is connected sequentially to the water inlet and the treatment agent inlet along the water flow direction. The meandering waterway includes at least two interconnected water conveyance paths arranged along a first direction. The water flow directions of the at least two water conveyance paths are different, and the projections of the water flow directions of the at least two water conveyance paths onto a reference plane at least partially overlap. The reference plane is perpendicular to the first direction.

[0006] In some embodiments, a water-blocking rib is provided between at least two connected water conveyance paths, and the water-blocking rib has a water outlet connecting the two water conveyance paths.

[0007] In some embodiments, at least two water conveying paths include three water conveying paths arranged sequentially along the first direction. The three water conveying paths are provided with two water-blocking ribs respectively. The water outlets on the two water-blocking ribs are arranged along the second direction and staggered along the first direction. The second direction is perpendicular to the first direction.

[0008] In some embodiments, the three water flow paths include: The first water conveyance path is connected to the water inlet; The second water conveyance path is connected to the first water conveyance path; and The third water delivery path is connected to the second water delivery path and the treatment agent inlet. The water flow directions of the first water conveying path, the second water conveying path, and the third water conveying path all extend along the second direction, and the water flow directions of the first water conveying path and the third water conveying path are opposite to the water flow direction of the second water conveying path.

[0009] In some embodiments, the meandering waterway further includes: A mixing chamber is connected to the treatment agent inlet and the third water supply path, and the mixing chamber is used to mix the water and the laundry treatment agent. The first water conveying path, the second water conveying path, the third water conveying path, and the mixing chamber are arranged sequentially along the first direction, and their projections along the first direction in the reference plane at least partially overlap.

[0010] In some embodiments, the treatment agent inlet is located at the end of the meandering waterway.

[0011] In some embodiments, the waterway further includes: The water inlet and water outlet are connected in sequence. The water inlet, the meandering waterway, and the water outlet are provided with an inlet. The connection between the water outlet and the meandering waterway is located below the water inlet.

[0012] In some embodiments, the waterway further includes: The water inlet channel is provided with the water inlet and is connected to the meandering waterway; and The pressure relief water passage has a pressure relief inlet and a pressure relief outlet. The pressure relief inlet is connected to the water inlet passage, and the pressure relief outlet is used to connect to the clothing processing chamber of the clothing processing equipment.

[0013] In some embodiments, the meandering waterway is located between the pressure relief inlet and the treatment agent inlet.

[0014] In some embodiments, the waterway further includes: The non-detour waterway extends along the first direction and is located between the pressure relief inlet and the inlet of the detour waterway.

[0015] In some embodiments, the pressure relief water path includes: At least two pressure relief flow paths are connected and have different water flow directions. At least one pressure relief flow path is provided with a pressure relief inlet, and at least another pressure relief flow path is provided with at least one pressure relief outlet.

[0016] In some embodiments, along the thickness direction of the dispensing device, the pressure relief inlet is higher than the bottom wall of the pressure relief flow path in which the pressure relief inlet is located.

[0017] In some embodiments, at least one of the pressure relief flow paths is provided with a flow slowing structure, which is used to slow down the flow velocity of water flowing through the pressure relief flow path.

[0018] In some embodiments, the slow-flow structure includes: At least two sets of flow-slowing ribs are provided on two opposite inner walls of the pressure relief flow path. Each set of flow-slowing ribs includes at least one flow-slowing rib. The extension direction of the flow-slowing rib is inclined to the direction of incoming water, and the extension direction of the flow-slowing rib has a component opposite to the direction of incoming water.

[0019] In some embodiments, multiple flow-slowing ribs in the two groups of flow-slowing ribs are arranged along a first direction, and the lengths of two adjacent flow-slowing ribs in the same group are different along the first direction; and / or, the lengths of two flow-slowing ribs arranged opposite each other in different groups along a second direction are different, and the second direction is perpendicular to the first direction.

[0020] Secondly, embodiments of this application provide a garment processing device, which includes a main body and the aforementioned dispensing device, wherein the dispensing device is installed on the main body.

[0021] Based on the above embodiments, by setting a detour water path in the water path of the dispensing device, the detour water path includes at least two water delivery paths arranged along a first direction with different water flow directions, and whose projections at least partially overlap in a reference plane perpendicular to the first direction. When water enters the detour water path from the inlet, it will form a turning flow in the water delivery paths in different directions, generating a turbulence or slowing effect. Subsequently, it will at least partially converge with the laundry detergent entering from the treatment agent inlet in the detour water path. The turning and turbulence of the water flow can break the limitations of natural diffusion, enhance the impact and stirring effect on the laundry detergent, avoid the problem that the laundry detergent is difficult to dissolve and disperse by relying only on a small amount of water flow, reduce the phenomenon of laundry detergent agglomeration and excessively high local concentration, and thus make the concentration of the mixed laundry detergent solution more uniform, improving the washing effect of clothes. Meanwhile, the resistance and turbulence generated when the water flow changes direction will interfere with the backflow trend and increase the backflow resistance, thereby effectively preventing the backflow phenomenon and ensuring that the water flow enters the subsequent stage in a stable and fully disturbed state. Ultimately, this achieves uniform distribution of the laundry detergent solution concentration into the laundry treatment chamber, effectively improving the laundry washing effect and reducing detergent waste.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0027] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] The first aspect of this application discloses a garment processing device. This garment processing device can be a washing machine or a washer-dryer combo, etc. The garment processing device includes a main body and a dispensing device, the dispensing device being installed in the main body. The main body has a garment processing chamber for holding the garments to be processed. The dispensing device is used to dispense a garment processing agent into the garment processing chamber. The garment processing agent can be, but is not limited to, laundry detergent, fabric softener, etc., and after being dispensed, it is transported into the garment processing chamber to achieve the washing and processing of the garments.

[0031] Currently, most washing machines use a cavity structure in their detergent dispensing devices to mix detergent and water, aiming for thorough fusion. However, in existing technologies, the cavity structure of the dispensing device is usually quite simple. After water and detergent enter, mixing is achieved solely through natural diffusion and the slight impact of water flow. This makes it difficult for the detergent to completely dissolve and disperse, easily leading to detergent agglomeration and locally excessively high concentrations. Ultimately, this results in uneven concentration of the detergent solution in the washing drum, affecting the washing effect on clothes.

[0032] To resolve the above issues, please refer to [link / reference]. Figures 1 to 3The second aspect of this application discloses a dispensing device 100. In this embodiment, the dispensing device 100 has a box-like structure, including a laundry detergent box 1 and a dispensing box, both of which are rectangular for easy fitting. The dispensing box and the laundry detergent box 1 are movably connected by rotation or sliding, and the dispensing box has multiple dispensing chambers to accommodate different laundry detergents such as laundry liquid and fabric softener. Specifically, when the dispensing box is moved to the dispensing position, the user can conveniently dispense the laundry detergent into the dispensing chamber. After dispensing, the user can return the dispensing box to its storage position in the laundry detergent box 1 by operating the dispensing box again.

[0033] The laundry detergent dispenser 1 has a water inlet 11, a detergent inlet 12, and a water passage 13. The dispenser 1 consists of a body 10 and a lid 20. The lid 20 is placed on the body 10 to form the water passage 13. The water inlet 11 is used to input water, and the detergent inlet 12 is used to input the laundry detergent. The water inlet 11 is connected to a water inlet pipe, and the detergent inlet 12 is connected to a dispensing pump. The water inlet pipe delivers water to the dispenser 1, and the dispensing pump pumps the laundry detergent from the dispenser into the detergent inlet 12. The dispensing pump can be an electric pump, a pneumatic pump, or a negative pressure pump, etc. It should be noted that the dispensing pump can be customized according to the number of dispensing chambers. For example, when there are two dispensing chambers, the dispensing pump is a dual-pump structure to ensure that the laundry detergent in each dispensing chamber can be delivered.

[0034] The waterway 13 includes a meandering waterway 131. Specifically, the components of the meandering waterway 131 are designed inside the housing 10, forming a completely enclosed channel when the cover 20 is closed. The meandering waterway 131 connects sequentially to the inlet 11 and the treatment agent inlet 12 along the water flow direction. The water flow direction of the meandering waterway 131 is... Figure 3 The red dashed line in the diagram represents the meandering waterway 131, which includes at least two interconnected water flow paths 1311 arranged along the first direction. The water flow directions of the at least two water flow paths 1311 are different; here, the water flow direction is defined as the main direction of the water flow within the water flow path 1311. The projections of the water flow directions of the at least two water flow paths 1311 onto the reference plane at least partially overlap, and the reference plane is perpendicular to the first direction. The reference plane here can be specifically understood in conjunction with the first direction: if the first direction is the width direction of the clothing treatment agent box 1 (e.g.,...) Figure 1In the context of box 10 (pointing from left to right), the reference plane is a virtual plane perpendicular to the width direction, which is the plane formed by the length direction (front to rear) and height direction (top to bottom) of box 10. "At least partially overlapping projections of the water flow direction onto the reference plane" means that the trajectories projected onto the plane formed by the length and height of the different water flow paths 1311 intersect or overlap, and the projections of their respective water flow directions onto the reference plane may overlap. This design requires the water flow to turn multiple times in the water flow paths 1311 arranged along the width direction, thus creating a stronger turbulence effect and providing a structural basis for the thorough mixing of water and laundry detergent. It should be noted that "at least partially overlapping projections of the water flow direction onto the reference plane" can mean that all different water flow paths 1311 overlap, for example... Figure 3 The 1311A and 1311B shown are completely overlapping in the reference plane; they may also be at least partially overlapping, for example, if the flow path is not. Figure 3 The flow path shown is not a horizontal flow path, but a flow path that forms a certain angle with the horizontal line.

[0035] Based on the above embodiments, by setting a detour water path 131 in the water path 13 of the dispensing device 100, the detour water path 131 includes at least two water conveyance paths 1311 arranged along a first direction with different water flow directions and whose projections at least partially overlap in a reference plane perpendicular to the first direction. When water enters the detour water path 131 from the inlet 11, it will form a turning flow in the water conveyance paths 1311 in different directions, generating a turbulence or slowing effect. Subsequently, it will at least partially converge with the laundry detergent entering from the treatment agent inlet 12 in the detour water path 131. The turning and turbulence of the water flow can break the limitations of natural diffusion, enhance the impact and stirring effect on the laundry detergent, avoid the problem that the laundry detergent is difficult to dissolve and disperse by relying only on a small amount of water flow, reduce the phenomenon of laundry detergent agglomeration and excessively high local concentration, and thus make the concentration of the mixed laundry detergent solution more uniform, improving the washing effect of clothes. Meanwhile, the resistance and turbulence generated when the water flow changes direction will interfere with the backflow trend and increase the backflow resistance, thereby effectively preventing the backflow phenomenon and ensuring that the water flow enters the subsequent stage in a stable and fully disturbed state. Ultimately, this achieves uniform distribution of the laundry detergent solution concentration into the laundry treatment chamber, effectively improving the laundry washing effect and reducing detergent waste.

[0036] Reference Figure 2 and Figure 3In some embodiments, a water-blocking rib 13111 is provided between at least two interconnected water conveyance paths 1311. The water-blocking rib 13111 has a water outlet 13112 connecting the two water conveyance paths 1311. The water-blocking rib 13111 may not be an additional blocking structure independent of the water conveyance path 1311, but rather it may be formed as part of the inner wall of the water conveyance path 1311, protruding and resembling a baffle separating adjacent water conveyance paths 1311, directly constituting the boundary at the turning point of the water conveyance path 1311. Adjacent water conveyance paths 1311 are transitioned by the water-blocking rib 13111. After the water flows out from the upstream water conveyance path 1311, its flow direction is changed by the guiding effect of the water-blocking rib 13111, and then it enters the downstream water conveyance path 1311 through the water outlet 13112 on the water-blocking rib 13111. This baffle-type water-blocking rib 13111 design not only forces the water flow to turn along a preset path through its own shape, avoiding disorderly diffusion of the water flow, but also narrows the water flow channel through the water outlet 13112, accelerating the local water flow speed and further enhancing the disturbance effect of the water flow, creating conditions for the full mixing of water and clothing treatment agent. At the same time, its integrated structural design can also improve the overall structural strength of the meandering water channel 131.

[0037] In some embodiments, at least two water flow paths 1311 include three water flow paths 1311 arranged sequentially along a first direction. Each of the three water flow paths 1311 has two corresponding water-blocking ribs 13111. The water inlets 13112 on the two water-blocking ribs 13111 are arranged along a second direction and staggered along the first direction, with the second direction perpendicular to the first direction. Considering the structure of the clothing treatment agent box 1, if the first direction (e.g....) Figure 3 The first direction is its width direction (e.g., from the left side of the box 10 to the right side), and the second direction is its length direction (e.g., from the front end of the box 10 to the rear end). The two baffles 13111 form the turning boundary between two adjacent water conveyance paths 1311. The water inlets 13112 arranged along the length direction can guide the water flow to form a lateral offset from the front end to the rear end or from the rear end to the front end when turning. The misalignment in the width direction makes the connecting path of the three water conveyance paths 1311 form a non-linear tortuous trajectory. After the water flow enters the middle water conveyance path 1311 from the first water conveyance path 1311 through the water inlet 13112 on the first baffle 13111, it needs to adjust its flow direction again to match the position of the water inlet 13112 misaligned along the width direction on the second baffle 13111. In this process, continuous turning disturbances are generated, which significantly enhances the turbulence of the water flow. This structural design, through the staggered arrangement of the water inlet 13112 along its length and width, allows the water flow to advance along the width while simultaneously forming a multi-dimensional flow pattern along the length, thereby improving the contact and mixing efficiency with the laundry detergent and reducing uneven local concentration.

[0038] In some implementations, the three water conveyance paths 1311 include a first water conveyance path 1311A, a second water conveyance path 1311B, and a third water conveyance path 1311C. The first water conveyance path 1311A is connected to the inlet 11. The second water conveyance path 1311B is connected to the first water conveyance path 1311A. The third water conveyance path 1311C is connected to the second water conveyance path 1311B and the treatment agent inlet 12. The water flow directions of the first water conveyance path 1311A, the second water conveyance path 1311B, and the third water conveyance path 1311C all extend along a second direction, and the water flow directions of the first water conveyance path 1311A and the third water conveyance path 1311C are opposite to the water flow direction of the second water conveyance path 1311B. Considering that the first direction is the width of the garment treatment agent box 1 and the second direction is the length, the three water flow paths 1311 all extend from the front end to the rear end or from the rear end to the front end of the box body 10 to form an alternating flow path. Specifically, after the water enters the first water flow path 1311A from the inlet 11, it flows in a certain direction along the length. When it enters the second water flow path 1311B through the water outlet 13112 of the first baffle rib 13111, it turns to the opposite length direction. Then, it enters the third water flow path 1311C through the water outlet 13112 of the second baffle rib 13111, and turns to the same length direction as the first water flow path 1311A, finally flowing to the treatment agent inlet 12. This alternating reverse flow design along the same direction (length direction), combined with the staggered arrangement of the water inlet 13112 and the water baffle 13111 in the width direction, causes the water flow to form a reciprocating turning impact during the meandering process, further aggravating the turbulent state of the water flow, providing more sufficient disturbance conditions for subsequent mixing with the clothing treatment agent, and promoting the dissolution and dispersion of the clothing treatment agent.

[0039] In some embodiments, the detour water path 131 further includes a mixing chamber 1312, which is connected to the treatment agent inlet 12 and the third water delivery path 1311C. The water supplied to the mixing chamber 1312 mixes with the laundry treatment agent within the mixing chamber 1312. The first water delivery path 1311A, the second water delivery path 1311B, the third water delivery path 1311C, and the mixing chamber 1312 are arranged sequentially along a first direction, and their projections along the first direction onto a reference plane at least partially overlap. Considering that the first direction is the width direction of the laundry treatment agent box 1 and the reference plane is a plane formed by the length and height directions, the three water delivery paths 1311 and the mixing chamber 1312 are arranged sequentially from left to right (or right to left) along the box body 10, and their projection areas on the length and height planes intersect or overlap. This arrangement allows the meandering water path 131 to occupy minimal space along its length, accommodating the compact internal structure of the laundry detergent dispenser 1. Simultaneously, the three water flow paths 1311 create a reciprocating, agitated flow that directly flows into the connected mixing chamber 1312, where it rapidly merges with the laundry detergent entering from the detergent inlet 12 within the limited space corresponding to the overlapping projection. The agitated kinetic energy carried by the water flow continues to act within the mixing chamber, preventing the laundry detergent from becoming dispersed and reducing mixing efficiency. This further ensures thorough mixing of water and laundry detergent, minimizing agglomeration and uneven concentration.

[0040] In some embodiments, the treatment agent inlet 12 is located at the end of the meandering water path 131. Thus, the water flows through at least two water flow paths 1311 with different flow directions and overlapping projections, completing its flow within the meandering water path 131 before reaching the treatment agent inlet 12. This arrangement can extend the water flow path by meandering through the water path 131, allowing for a more thorough pre-flow process before the water and treatment agent mix at the inlet, thereby improving the mixing effect.

[0041] Reference Figures 1 to 3 In some embodiments, the water passage 13 further includes an inlet water passage 132 and an outlet water passage 133. The inlet water passage 132, the bypass water passage 131, and the outlet water passage 133 are connected in sequence. The inlet water passage 132 is provided with an inlet 11, and the connection 137 between the outlet water passage 133 and the bypass water passage 131 is located below the inlet water passage 132. The water flow direction of the inlet water passage 132 is... Figure 3 The brown dashed line in the middle indicates the direction of water flow in water outlet 133. Figure 3The blue dotted line illustrates this structural design. Water enters the inlet channel 132 from the inlet 11, flows upwards along a relatively high path to the meandering channel 131, where it is agitated before exiting through the lower connecting port 137 into the outlet channel 133. Utilizing the drop in water flow due to gravity enhances the flow dynamics at the junction of the meandering channel 131 and the outlet channel 133, preventing stagnation during turning or mixing. Simultaneously, the lower connecting port 137 guides the mixed water carrying the laundry detergent more smoothly towards the outlet channel 133, reducing localized accumulation of the mixed solution due to a gentle path, and further ensuring that the mixed solution is delivered evenly and efficiently to the laundry treatment chamber.

[0042] In some implementations, the dispensing device 100 further includes an atomizing nozzle connected to the water outlet 133. The mixed water and laundry detergent are then delivered to the atomizing nozzle via the water outlet 133, where they are atomized into tiny droplets and sprayed out. This design, through atomization, allows the detergent to contact the clothes being washed more evenly and widely, improving its efficiency. Simultaneously, because the meandering water path 131 effectively regulates the water flow, the mixture entering the atomizing nozzle has a stable pressure and concentration, ensuring consistent atomization and avoiding uneven atomization caused by unstable water flow, further optimizing the overall performance of the dispensing device 100.

[0043] Reference Figure 2 and Figure 3 In some embodiments, water passage 13 further includes a pressure relief water passage 134, which has a pressure relief inlet 1341 and a pressure relief outlet 1342. The pressure relief inlet 1341 is connected to the inlet water passage 132, and the pressure relief outlet 1342 is used to connect to the garment processing chamber of the garment processing equipment. The water flow direction of the pressure relief water passage 134 is... Figure 3 The green dotted line indicates that when the water pressure in the inlet water path 132 is too high, some water can enter the pressure relief water path 134 through the pressure relief inlet 1341 and flow directly into the laundry treatment chamber through the pressure relief outlet 1342. This avoids excessive pressure in the detour water path 131, which could cause excessively fast water flow and violent disturbance, affecting the mixing effect of water and laundry detergent. It also prevents excessive pressure from causing long-term damage to the water-blocking ribs 13111 and the water outlet 13112 of the detour water path 131, ensuring the stability of the water path 13 system. Furthermore, the water diverted to the pressure relief water path 134 can directly participate in the laundry washing process, avoiding water waste and achieving synergy between pressure regulation and water utilization.

[0044] In some other embodiments, the water flow in the inlet water passage 132 is at least partially diverted to the pressure relief water passage 134 to reduce the water flow pressure in the detour water passage 131.

[0045] In some implementation schemes, the detour water path 131 is located between the pressure relief inlet 1341 and the treatment agent inlet 12. On one hand, this arrangement allows some of the water flowing in the inlet water path 132 to pass through the pressure relief inlet 1341 before flowing into the detour water path 131, where some is diverted to the pressure relief water path 134 for pressure reduction, while the remaining water continues to flow into the detour water path 131. When the diverted and depressurized water enters the detour water path 131, the pressure is within a more suitable range. This allows for sufficient turbulence to be created through the detour structure, providing conditions for subsequent mixing, while preventing excessively high pressure from causing excessively fast flow velocity and strong impact. After the water has formed stable turbulence in the detour water path 131, it then mixes with the laundry treatment agent input at the treatment agent inlet 12, preventing the laundry treatment agent from being washed away by the high-speed water flow upon entry, ensuring sufficient dissolution and dispersion. Meanwhile, the pre-positioning of the pressure relief stage can mitigate the impact of excessive pressure on the bypass water channel 131 structure in advance, reducing wear and tear on components such as the baffle rib 13111 and the inlet 13112, and extending the service life of the water channel 13. On the other hand, in the prior art, the pressure relief port is usually located on the wall of the mixing chamber. With this arrangement, the water-liquid mixture can easily flow out through the pressure relief port, resulting in detergent waste and potentially contaminating the pressure relief flow path. In this application, by placing the bypass water channel 131 between the pressure relief inlet 1341 and the treatment agent inlet 12, after the water-liquid mixture wants to flow out of the pressure relief inlet 1341, it must flow back through the bypass water channel 131. The bypass water channel is equipped with at least two interconnected drainage flow paths 1311 arranged in the first direction, so it is not so easy for the mixture to flow back. This arrangement can effectively prevent the water-liquid mixture from flowing out through the pressure relief port, thus preventing detergent waste.

[0046] In some embodiments, waterway 13 further includes a non-detour waterway 135 extending along the first direction, and the non-detour waterway 135 is located between the pressure relief inlet 1341 and the inlet of the detour waterway 131. The flow direction of the non-detour waterway 135 is... Figure 3The purple dotted line in the diagram, combined with the width direction of the clothing treatment agent box 1 in the first direction, indicates that the non-detour water path 135 extends in a straight line from the left to the right (or from the right to the left) along the box body 10, receiving the remaining water flow after being diverted through the pressure relief inlet 1341. The water flow first undergoes a brief straight flow through the non-detour water path 135 to stabilize the diverted water flow state before entering the detour water path 131. This design avoids the turbulent impact that may occur when the diverted water flows directly into the meandering structure, allowing the water to enter the meandering water path 131 in a more stable initial state. This ensures that the water-blocking ribs 13111 and the staggered water inlet 13112 of the meandering water path 131 can fully exert their turbulence-causing effect, forming a controllable and effective water flow disturbance. This lays a more stable foundation for subsequent mixing with the clothing treatment agent. At the same time, the straight-line non-meandering water path 135 simplifies the connection path between the pressure relief inlet 1341 and the inlet of the meandering water path 131, adapting to the internal spatial layout of the box 10.

[0047] Optionally, the pressure relief water path 134 includes at least two pressure relief flow paths 1343, which are connected and have different flow directions. At least one pressure relief flow path 1343 is provided with a pressure relief inlet 1341, and at least the other pressure relief flow path 1343 is provided with at least one pressure relief outlet 1342. This multi-stage turning structure design requires the water flow diverted from the inlet water path 132 to the pressure relief water path 134 to undergo multiple turns before being discharged from the pressure relief outlet 1342. The turning process can buffer the diverted water flow, further reducing the flow velocity and pressure of the water in the pressure relief water path 134, preventing the diverted water flow from directly impacting the clothing processing chamber corresponding to the pressure relief outlet 1342 at high speed, and also reducing the indirect impact of the pressure relief water flow on other components of the water path 13. Furthermore, by placing the pressure relief inlet 1341 and pressure relief outlet 1342 in pressure relief flow paths 1343 in different directions, the position of the water inlet path 132 in the garment treatment agent box 1 and the connection requirements of the garment treatment chamber can be flexibly adapted. While achieving the pressure relief function, the spatial layout of the overall water path 13 is optimized, avoiding layout conflicts with the meandering water path 131, the treatment agent inlet 12, and other structures. At the same time, the outlet layout can be flexibly configured according to the actual pressure relief requirements. Pressure relief outlets 1342 can be set in each pressure relief flow path 1343, or multiple pressure relief outlets 1342 can be set in a single pressure relief flow path 1343. This diversified configuration can further adapt to the pressure relief intensity and range requirements under different working conditions. For example, multi-compartment garment treatment equipment can achieve zoned pressure relief through a single path with multiple outlets, improving the adaptability and practicality of the overall pressure relief system.

[0048] In some implementations, along the thickness direction of the dispensing device 100, the pressure relief inlet 1341 is higher than the bottom wall of the pressure relief flow path 1343 where the pressure relief inlet 1341 is located. The thickness direction of the dispensing device 100 actually refers to its direction along the depth of the equipment or perpendicular to the surface of the housing 10 when it is assembled into the garment processing equipment. Thus, the pressure relief inlet 1341 is positioned relatively high within its respective pressure relief flow path 1343. When water from the inlet water path 132 is diverted to the pressure relief inlet 1341, it must overcome a certain height difference to enter the pressure relief flow path 1343. This height setting naturally limits the flow of water diverted to the pressure relief flow path 134. Pressure relief and diversion are only activated when the pressure in the inlet water path 132 reaches a certain level sufficient to push the water flow to the height of the pressure relief inlet 1341. This avoids unnecessary water diversion due to slight pressure fluctuations, ensures the stability of the water volume entering the bypass water path 131, and ensures that the mixing ratio of water and garment processing agent is not affected by excessive diversion. Meanwhile, the higher position of the pressure relief inlet 1341 can reduce the water accumulation in the pressure relief flow path 1343, allowing the diverted water to flow more smoothly along the bottom wall to the subsequent pressure relief flow path 1343, thereby improving the pressure relief efficiency.

[0049] In some implementations, at least one pressure relief flow path 1343 is equipped with a flow-slowing structure 136, which is used to reduce the flow velocity of water flowing through the pressure relief flow path 1343. This flow-slowing structure 136 can take the form of a flow-disrupting rib protruding from the inner wall of the pressure relief flow path 1343, a flow-limiting protrusion spaced at intervals along the water flow direction, or an expansion cavity formed by locally enlarging the cross-section of the flow path. When the water diverted to the pressure relief flow path 134 passes through the flow-slowing structure 136, its flow path will generate turbulence due to structural obstruction or spatial changes, the kinetic energy of the water will be dispersed and consumed, and the flow velocity will be effectively reduced. This design can further weaken the impact intensity of the pressure relief water flow, and the reduced flow velocity can also reduce the long-term scouring and loss of the inner wall of the pressure relief flow path 1343, making the pressure relief process more stable and controllable.

[0050] In some embodiments, the flow-slowing structure 136 includes at least two sets of flow-slowing ribs 1361, which are disposed on two opposite inner walls of the pressure relief flow path 1343. Each set of flow-slowing ribs 1361 includes at least one flow-slowing rib 1361, and the extension direction of the flow-slowing rib 1361 is parallel to the direction of incoming water (e.g., Figure 3The direction of the green arrow in the middle is inclined, and the extension direction of the flow-slowing rib 1361 has a component opposite to the direction of incoming water. When the water flows into the pressure relief flow path 1343 equipped with the flow-slowing rib 1361, the flow-slowing ribs 1361 on the inner wall form an interlaced layout. The water first contacts one side of the flow-slowing rib 1361. Because the extension direction of the flow-slowing rib 1361 is inclined to the direction of incoming water and has an opposite component, part of the water flow will be guided to the middle of the flow path, while part will be diverted to the opposite direction of incoming water. Subsequently, it will encounter the obstruction of the other side of the flow-slowing rib 1361. Under the action of the reverse component of its extension direction, the flow direction will be deflected again and a reverse component force will be generated. This interlaced layout, combined with the inclined guide with a reverse component, makes the water flow continuously change its flow direction when passing through the flow-slowing structure 136, and the reverse component force continuously offsets the kinetic energy of the water flow, so that the kinetic energy is gradually consumed and the flow velocity is significantly reduced. Meanwhile, the tortuous channel formed between adjacent flow-slowing ribs 1361 can further extend the water flow path, enhance the flow-slowing effect, and prevent the pressure-relief water flow from entering the subsequent flow path at a high speed. Together with the multi-stage turning design of the pressure-relief water path 134, they can achieve smooth pressure relief and reduce the impact on the clothing processing chamber.

[0051] In some implementations, multiple flow-slowing ribs 1361 within the two sets of flow-slowing ribs 1361 are arranged along a first direction, and the lengths of adjacent flow-slowing ribs 1361 within the same set are different along the first direction. This design causes the flow-slowing ribs 1361 in the same set to form an alternating arrangement of long and short ribs as they extend along the width direction. The extension distance of adjacent flow-slowing ribs 1361 in the length direction (second direction) differs. When water flows through these flow-slowing ribs 1361 along the width direction, it will encounter varying degrees of obstruction due to the changes in rib length. Shorter flow-slowing ribs 1361 can only partially intercept the middle of the water flow, while longer flow-slowing ribs 1361 can extend deeper into the flow path, creating more significant disturbance to the water flow. This results in a turbulent zone with uneven flow velocity within the area of ​​the same set of flow-slowing ribs 1361, further consuming the kinetic energy of the water.

[0052] In some implementation schemes, the lengths of the two flow-slowing ribs 1361 arranged opposite each other along the second direction in different groups are different, and the second direction is perpendicular to the first direction. That is, the lengths of the flow-slowing ribs 1361 on the left inner wall and the flow-slowing ribs 1361 on the right inner wall are mismatched. For example, when the left side is a long rib, the right side has a corresponding short rib, or the extension length of the left rib is misaligned with that of the right side. This asymmetrical design avoids the relative ribs forming an upward obstruction, causing the turning trajectories of the water flow after impacting the ribs on both sides to be staggered, making it impossible to form a stable convection path. This forces the water flow to form more complex vortices and turbulence in the flow path. In conjunction with the alternating design of long and short ribs in the same group, it breaks the regular flow of water from multiple dimensions, maximizes the flow-slowing effect, and ensures that the depressurized water flow enters the subsequent flow path in a stable state.
