Description

Technical Field

[0001] This application relates to the technical field of clothing processing equipment, and specifically to a cleaning device for clothing processing equipment and a clothing processing equipment. Background Technology

[0002] For garment handling equipment such as washing machines, dryers, and washer-dryer combos, filters are key components used to remove debris from the airflow (such as lint, clothing fibers, or other particulate matter shed from clothing). As garment handling equipment is used over time, debris accumulates on the filters, causing blockages. This not only reduces airflow efficiency but may also lead to overheating or malfunction of the garment handling equipment.

[0003] Therefore, there is still a real need to improve the filter cleaning aspect of clothing processing equipment. Utility Model Content

[0004] In view of this, the purpose of embodiments of this application is to provide an improved cleaning apparatus for a garment processing device and an improved garment processing device, so as to overcome at least one of the above-mentioned disadvantages and / or other possible disadvantages not mentioned herein.

[0005] According to a first aspect of this application, a cleaning apparatus for a garment processing device is provided, wherein the garment processing device has a filter screen suitable for filtering debris, the cleaning apparatus comprising: a flow channel member configured to supply a cleaning medium, the flow channel member having a first flow channel space; and a spray member having: a second flow channel space communicating with the first flow channel space; and a discharge opening configured to allow the cleaning medium to be discharged from the second flow channel space toward the filter screen, wherein the spray member is clearance-fitted with the flow channel member in the radial and axial directions, and the cleaning apparatus is configured to allow the spray member to move relative to the flow channel member to remove debris from the filter screen during a cleaning medium discharge operation. Therefore, by designing the spray component to be movable relative to the flow channel component and setting radial and axial clearances between the two, the frictional resistance between the two moving parts is reduced, and the water flow in the gap can also play a lubricating role, ensuring that the spray component can move freely relative to the flow channel component. On the other hand, it allows even a small spray component with a small number of discharge openings to cover a large cleaning area of ​​the filter screen with the cleaning medium (such as water) through its own movement, thereby saving the installation space of the cleaning device itself and providing greater flexibility for the layout of other functional components of the garment processing equipment.

[0006] According to an optional embodiment, the spray component and the flow channel component are connected in a shock-absorbing manner. This not only reduces vibration noise caused by the collision between the spray component and the flow channel component during the operation of the garment processing equipment, but also protects these two moving parts from vibration and impact damage, extending the service life of the cleaning device and improving product reliability.

[0007] According to an optional embodiment, the radial gap between the spray component and the flow channel component after assembly is 0.1 mm to 0.2 mm, and the axial gap is 0.5 mm to 1 mm. Thus, on the one hand, the gap is not too large to ensure sufficient water flow to drive the spray component to move normally, and the deviation in movement position is controllable; on the other hand, the gap is not too small to ensure that water can flow out from the gap and wash away lint or debris within the gap.

[0008] According to an alternative embodiment, the cleaning device is configured to allow the spray member to rotate relative to the flow channel member in the operating state. The spray member has multiple discharge openings with different orientations to allow the cleaning medium to discharge from these openings, generating a torque that drives the spray member to rotate. Thus, the principle of the reaction force of water flow is cleverly utilized to drive the rotation of the spray member, eliminating the need for an additional drive device and relying solely on the kinetic energy of the cleaning medium itself to achieve rotation, significantly simplifying the overall product structure.

[0009] According to an alternative embodiment, the spray member has a through-hole configured to allow the flow channel member to pass through it. The through-hole has a central axis. The flow channel member includes a flushing arm with a first flow channel and a plug with a second flow channel. The plug is configured to pass through the through-hole and connect to the flushing arm to allow communication between the first and second flow channels to form a first flow channel space. Thus, by designing the flow channel member as two independent components with their respective flow channels cooperating to form a first flow channel space for the flow of cleaning media, not only is the manufacturing process simplified, allowing for the use of suitable materials and processing methods, but also a connected first flow channel space is achieved in the assembled state. This allows the cleaning media to flow from the first flow channel to the second flow channel and then through the spray member cooperating with the flow channel member to the filter screen, ensuring an effective media transport path.

[0010] According to an optional embodiment, the plurality of discharge openings on the spray member are arranged such that, in the operating state, the cleaning medium exiting from these discharge openings covers the entire filter screen. This fully utilizes the characteristics of rotational motion, achieving complete coverage cleaning of a large-area filter screen with a miniaturized cleaning device, thus ensuring the filtration performance of the garment processing equipment.

[0011] According to an optional embodiment, the plurality of discharge openings on the spray member include N first openings located in the central region and M second openings located on both sides of the central region, where M and N are positive integers. This prevents the central region of the filter from being left uncovered by the cleaning medium, thereby ensuring that all parts of the filter are thoroughly cleaned.

[0012] According to an optional embodiment, the rinsing arm has a first end face facing the spray member, the plug has a second end face facing the spray member, and the cleaning device includes a first buffer member located between the first end face and the spray member, and a second buffer member located between the second end face and the spray member. Thus, these two buffer members effectively absorb the axial movement that may occur when the spray member rotates, preventing hard impacts and noise generation, significantly improving the user experience and product reliability.

[0013] According to an alternative embodiment, the flushing arm and the plug form a sealed flow channel in the connection area that restricts the flow of cleaning medium from the first flow channel space. Thus, the sealed flow channel formed by the flushing arm and the plug ensures that most of the water flow is ejected from the discharge opening, maintaining sufficient cleaning pressure and flow rate without the need for a dedicated sealing element.

[0014] According to an optional embodiment, the flushing arm has an inner ring flange and an outer ring flange extending toward the plug, respectively. The plug has a protruding edge configured to extend between the inner ring flange and the outer ring flange. The inner ring flange, the outer ring flange, and the protruding edge together form the sealing flow channel. Thus, on the one hand, the design of the protruding edge extending between the inner and outer ring flanges serves a positioning and guiding function, ensuring the coaxiality of the flushing arm and the plug; on the other hand, the labyrinthine channel formed by the inner and outer ring flanges and the protruding edge significantly extends the leakage path and forces the water flow to change direction, increasing flow resistance and thereby achieving a sealing effect.

[0015] According to an optional embodiment, the sealed flow channel includes a first inlet section spatially connected to the first flow channel, the first inlet section being configured to have at least a flow component against gravity when the cleaning medium enters. Thus, when the cleaning medium needs to rise against gravity, gravity itself becomes an additional resistance factor, effectively slowing the flow velocity and increasing the residence time, thereby reducing leakage.

[0016] According to an optional embodiment, the sealing channel further includes a second inlet section extending from the first inlet section in a direction away from the spray member. Thus, the axial extension of the second inlet section further increases the leakage path length, enhancing the sealing effect.

[0017] According to one optional embodiment, the plug has P protrusions on the outer side of the convex edge, and the flushing arm has P recesses on the outer flange that allow the P protrusions to engage, where P is an integer greater than one. This enables quick and reliable assembly, and the snap-fit ​​connection also has a certain self-locking characteristic, making it less prone to loosening under vibration.

[0018] According to one optional embodiment, the plug has Q protrusions on the outer side of the convex edge, and the protrusions make line contact with the inner side of the outer ring flange, where Q is an integer greater than one. Thus, the line contact of the protrusions reduces the contact area, lowers assembly resistance, and allows the plug to be smoothly inserted into place; this design also compensates for manufacturing tolerances, achieves a reliable fit, and prevents wobbling at the connection point.

[0019] According to an optional embodiment, the spray component includes a first half-shell and a second half-shell that are independent of each other. The first half-shell and the second half-shell are connected to each other along the central axis to form the second flow channel space. The first half-shell is closer to the rinsing arm than the second half-shell, and the discharge opening is located on the second half-shell. This split design facilitates mold manufacturing. The first half-shell focuses on its fit with the flow channel component, while the second half-shell focuses on the arrangement of the discharge opening. When it is necessary to change the number or angle of the discharge opening, only the mold of the second half-shell needs to be replaced, improving product adaptability.

[0020] According to an optional embodiment, the first half-shell has a first through hole, and the second half-shell has a second through hole. The first through hole and the second through hole together form the through portion. The diameter of the first through hole is larger than the inner diameter of the first buffer member but smaller than its outer diameter, and the diameter of the second through hole is larger than the inner diameter of the second buffer member but smaller than its outer diameter. Therefore, on the one hand, this ensures stable installation of the buffer member and provides effective axial support; on the other hand, the cooperation between the through hole and the buffer member also provides a certain degree of sealing, reducing axial water leakage.

[0021] According to an optional embodiment, the outer wall of the plug is provided with a stepped surface, and the first buffer member is located simultaneously between the first end face and the stepped surface. The spray member is radially clearance-fitted with the outer wall of the plug located between the second end face and the stepped surface. Thus, the stepped surface provides an additional axial positioning surface for the first buffer member, constraining it simultaneously by both the first end face of the flushing arm and the stepped surface, improving installation stability.

[0022] According to an optional embodiment, the spraying component is axially positioned between the first and second buffer components and has a clearance fit with them. This ensures effective contact between the spraying component and the buffer components on both sides, reducing noise, while also avoiding stress concentration and jamming risks that could result from rigid constraints.

[0023] According to one alternative embodiment, the plug has a closed bottom on the side opposite to the spray member. This sealed bottom design not only provides good structural strength but also avoids pressure loss and flow reduction caused by bottom leakage, ensuring effective cleaning.

[0024] According to an optional embodiment, the plug has a diversion structure at the second flow channel to allow the cleaning medium to flow from the second flow channel into the second flow channel space in multiple diversions. This avoids excessively high or low local pressures, helps maintain stable injection pressure at each discharge opening, optimizes hydrodynamic performance, and improves cleaning efficiency and operational stability.

[0025] According to an optional embodiment, the diversion structure achieves diversion through multiple partition ribs, which are rotationally symmetrical with respect to the central axis and have a gradually increasing distance between adjacent partition ribs in a radially outward direction. Thus, the rotationally symmetrical arrangement of the partition ribs ensures circumferential pressure balance, avoiding the generation of eccentric forces; the partition ribs themselves also act as reinforcing ribs, improving the structural strength of the plug, and the gradually increasing distance between adjacent partition ribs also facilitates the smooth diversion of the cleaning medium from the plug to the spray component.

[0026] According to a second aspect of this application, a garment processing apparatus is provided, comprising: a garment receiving cavity; a gas passage communicating with the garment receiving cavity, the gas passage being configured to allow gas flow suitable for drying garments; a filter screen configured to filter out impurities from the garment receiving cavity from the gas passage; and a cleaning device for the garment processing apparatus provided in the embodiments of the first aspect above, wherein the cleaning device is arranged downstream of the filter screen along the gas flow direction. Thus, this garment processing apparatus particularly possesses the advantages mentioned in the embodiments above. Attached Figure Description

Detailed Implementation

[0045] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit the scope of protection of this application. Various embodiments may share the same view or multiple views for description, but not all features appearing in the same view should be interpreted as features that must be present in an embodiment.

[0046] For ease of understanding, the description provided in the background section of this application may be recalled. One object of this application is to provide a cleaning device for a garment processing apparatus, wherein the garment processing apparatus has a filter screen suitable for filtering debris, the cleaning device comprising: a flow channel member configured to supply a cleaning medium, the flow channel member having a first flow channel space; and a spray member having: a second flow channel space communicating with the first flow channel space; and a discharge opening configured to allow the cleaning medium to be discharged from the second flow channel space toward the filter screen, wherein the spray member is clearance-fitted with the flow channel member in the radial and axial directions, and the cleaning device is configured to allow the spray member to move relative to the flow channel member to remove debris from the filter screen during the operation of the cleaning medium discharge. Therefore, by designing the spray component to be movable relative to the flow channel component and setting radial and axial clearances between the two, the frictional resistance between the two moving parts is reduced, and the water flow in the gap can also play a lubricating role, ensuring that the spray component can move freely relative to the flow channel component. On the other hand, it allows even a small spray component with a small number of discharge openings to cover a large cleaning area of ​​the filter screen with the cleaning medium (such as water) through its own movement, thereby saving the installation space of the cleaning device itself and providing greater flexibility for the layout of other functional components of the garment processing equipment.

[0047] Exemplary embodiments of this application will now be described with reference to the accompanying drawings.

[0048] Figure 1 A schematic perspective view of a garment processing apparatus 2000 according to an exemplary embodiment of this application is shown; Figure 2 A simplified schematic diagram of the garment processing device 2000 during the drying of garments 2001 is shown; Figure 3 A simplified schematic diagram of the garment processing device 2000 cleaning the filter 2100 is shown.

[0049] like Figure 1 As shown, the garment processing equipment 1000 can be configured as a household washing machine, a household dryer, a household washer-dryer, or other types of garment processing equipment not shown herein. Preferably, the garment processing equipment 1000 is configured as a heat pump washer-dryer combo. Figure 1 The diagram also schematically illustrates the xyz coordinate system of the garment processing device 1000, where x represents the width direction of the garment processing device 1000, y represents the height direction of the garment processing device 1000 from bottom to top, and z represents the depth direction of the garment processing device 1000 from outside to inside. For clarity, this xyz coordinate system will be used as a basic reference in the subsequent accompanying drawings and descriptions.

[0050] Combination Figure 2The garment handling equipment 1000 may include a garment receiving cavity 2200 for washing and drying garments 2001, and a gas passage 2300 communicating with the garment receiving cavity 2200. In drying mode, the gas passage 2300 is activated to form a closed-loop gas flow as schematically indicated by a hollow arrow. Here, for example, a fan 2301 drives air through an evaporator for cooling and dehumidification and a condenser for heating in a heat pump system, forming dry, hot gas. This dry, hot gas is blown into the garment receiving cavity 2200, absorbing moisture from the garments 2001, becoming humid, hot gas. The humid, hot gas, carrying lint, fibers, and other debris detached from the garments 2001, flows out of the garment receiving cavity 2200 and into the return air section of the gas passage 2300. Figure 2 As shown, a filter 2100 is installed at the air outlet on the barrel wall, which is also the inlet of the return air section. The function of this filter 2100 is to intercept impurities (such as lint, fibers, etc.) in the gas before it returns to the heat pump system for reprocessing, preventing these impurities from clogging the heat pump components and affecting drying efficiency and product lifespan. Combined with... Figure 3 To clean debris (such as lint, fibers, etc.) trapped on the filter 2100, a cleaning device 1000, which will be described in detail below, is provided downstream of the filter 2100 along the direction of airflow. Here, the cleaning device 1000 is located on the clean side (i.e., the side without debris) of the filter 2100. After the drying process is completed, or during a specific maintenance procedure, the garment handling equipment 1000 can initiate a cleaning cycle. For example, water from an external water source 3000 or an internal water source (such as a condensate collection device) enters the cleaning device 1000 through an inlet valve, spraying water onto the filter 2100 (or...). Figure 3 (Illustrated schematically with dashed lines). These water flows penetrate the mesh of the filter 2100, washing away lint and other debris adhering to its upstream surface (i.e., the dirty side). The washed-off debris falls into the pipe or bucket below and is eventually discharged from the garment processing equipment 1000 in the next drainage process. It should be understood that in the garment processing equipment 1000, the air passage 2300 and the filter 2100 may have different arrangements and positions than shown in the illustration.

Figure 9 A partial longitudinal sectional perspective view of the flow channel component 1100 of a cleaning device 1000 according to an exemplary embodiment of this application is shown; Figure 10 A schematic perspective view of the plug 200 of the flow channel component 1100 of a cleaning device 1000 according to an exemplary embodiment of this application is shown; Figure 11 It shows along Figure 10 A schematic sectional perspective view of the section line DD; Figure 12 A longitudinal sectional perspective view of a cleaning device 1000 according to an exemplary embodiment of this application is shown; Figure 13 A longitudinal sectional perspective view of a cleaning device 1000 according to an exemplary embodiment of this application is shown.

[0052] like Figure 4 Combination Figures 1 to 3 As shown, the cleaning device 1000 is used for, for example Figure 2 The cleaning device 1000 shown includes a filter 2100. The cleaning device 1000 includes a flow channel component 1100 and a spray component 1200. The flow channel component 1100 serves as an introduction and distribution channel for a cleaning medium (e.g., tap water), and its interior forms a first flow channel space 1110. The flow channel component 1100 can be fixedly mounted on the internal structure of the cleaning device 2000, for example, fixed to a duct housing above the filter 2100. The spray component 1200 is a movable component, and its interior has a second flow channel space 1220, which communicates with the first flow channel space 1110 of the flow channel component 1100 to receive the cleaning medium from the flow channel component 1100, as shown in the diagram. Figure 13As shown, the bottom of the spray member 1200 (or the side facing the filter screen 2100) is provided with one or more discharge openings 1230. Here, the spray member 1200 is not fixedly connected to the flow channel member 1100, but is fitted onto the flow channel member 1100 with a clearance fit. Specifically, a certain gap can be reserved between them in the direction perpendicular to the filter screen (axial direction); a certain gap can also be reserved between them in the direction parallel to the filter screen (radial direction). In the working state, when the cleaning medium (e.g., tap water) is supplied into the flow channel member 1100 and flows towards the spray member 1200, the spray member 1200 can move relative to the flow channel member 1100. In a preferred embodiment, this movement is a rotational movement. As the spray member 1200 rotates, the water jet sprayed from its discharge openings 1230 sweeps across the entire surface of the filter screen 2100 like a scanning radar, thereby powerfully washing away attached debris and achieving the cleaning purpose. In another embodiment, not shown, this movement can also be a reciprocating translational motion. This dynamic cleaning method allows the cleaning device 1000 to cover and clean a large area of ​​the filter screen 2100 with a relatively small spray component 1200, significantly saving material costs and installation space compared to a static system that requires a large number of nozzles to cover the entire filter screen.

[0053] Preferably, the spray component 1200 and the flow channel component 1100 are connected by a shock-absorbing connection, for example, by providing a soft rubber buffer between the spray component 1200 and the flow channel component 1100. Since the cleaning device 1000 is typically integrally mounted on the drum system of the garment handling equipment 2000 or a component rigidly connected to it, the drum system generates severe vibrations during high-speed spin-drying in the washing machine. Because there is a clearance between the spray component 1200 and the flow channel component 1100 designed for smooth movement, without shock-absorbing measures, this severe external vibration would cause the spray component to move up and down within the axial clearance, resulting in high-frequency collisions with the hard plastic or metal surface of the flow channel component 1100, generating unpleasant noise and potentially damaging components. By using a shock-absorbing connection, when external vibrations cause the spray component 1200 to move, noise generation and component damage rates can be reduced, improving the user experience.

[0054] from Figures 4 to 6 As can be seen, the spray component 1200 has a through portion 1210, through which the flow channel component 1100 can pass through the entire spray component 1200. The through portion 1210 is located in the central region 1201 of the spray component 1200. The through portion 1210 has a central axis 1211. In the operating state of the cleaning device 1000, the spray component 1200 rotates relative to the flow channel component 1100 about the central axis 1211 (as...). Figure 4(The hollow arrow is shown as an example). Specifically, the shape of a local section of the flow channel member 1100 (specifically, the section that serves as the rotation axis) matches the inner contour of the through-hole 1210 of the spray member 1200 and passes through the through-hole 1210. The flow channel member 1100 is fixed in the garment handling device 1000, while the spray member 1200 is rotatably fitted onto this section of the flow channel member 1100 with radial and axial clearances. Thus, the flow channel member 1100 acts as a rotating stator and shaft, while the spray member 1200 acts as a rotor. In operation, the cleaning medium enters from the first flow channel space 1110 inside the fixed flow channel member 1100 into the second flow channel space 1220 of the rotatable spray member 1200, and is then sprayed out from the discharge opening 1230 at the bottom of the spray member 1200. Figure 6 As shown, the spray component 1200 preferably has a plurality of discharge openings 1230, which are not simply perpendicular to the bottom surface, but have different orientations (as shown in the figure). Figure 12 (Hollow arrows are schematically shown in the diagram), thereby generating a torque that drives the spray member 1200 to rotate when the cleaning medium is discharged from these discharge openings 1230. Specifically, the axes of these discharge openings 1230 have a predetermined deflection angle relative to the axis of the spray member 1200. Viewed from the bottom of the spray member 1200, the water outlet direction of each discharge opening 1230 is along a tangential direction. More specifically, the tangential components of multiple discharge openings 1230 all point to the same direction of rotation (e.g., all clockwise or all counterclockwise). When water is sprayed from these inclined discharge openings 1230, the water flow exerts a reaction force of equal magnitude and opposite direction on the spray member 1200. Since the water outlet direction has a tangential component, this reaction force also has a tangential component around the central axis 1211. The sum of the tangential components generated by the multiple discharge openings 1230 constitutes the total torque that drives the spray member 1200 to rotate. Through this passive design, relying solely on the force of the water flow itself, the spray component 1200 achieves automatic and continuous rotation, thus realizing thorough cleaning of the entire filter 2100 through dynamic scanning. Figure 6As shown, the bottom of the spray member 1200 can be divided into a central region 1201 and a surrounding peripheral region. The discharge openings 1230 are thus divided into two categories. The first category consists of N first openings 1231 located within the central region 1201. In this embodiment, N = 1, meaning there is only one first opening 1231. This first opening 1231 is essentially located at the center of the spray member 1200, and its spray direction is perpendicular to the bottom surface of the spray member 1200, i.e., pointing directly downwards. The main function of this first opening 1231 is to cover the central region that might be overlooked due to the outward tilt of other discharge openings 1230. Because its water flow direction is parallel to the axis of rotation, it does not generate a torque that drives rotation, nor does it generate a resisting torque that hinders rotation. The second category consists of 2M second openings 1232 located in the peripheral region. In this embodiment, M = 3, and these 2M second openings 1232 are preferably arranged symmetrically on both sides of the central region 1201, i.e., three second openings 1232 on each side. Unlike the first opening 1231, the spray directions of these six second openings 1232 are all at an angle to the vertical direction, and their projections onto the horizontal plane have a significant tangential component. The tangential components of all six second openings 1232 point in the same direction of rotation (e.g., clockwise), and their resultant force constitutes the main power source driving the rotation of the spray component 1200. Here, the specific values ​​of M and N (both positive integers) can be flexibly adjusted according to factors such as filter size, required torque, and water pressure.

[0055] like Figure 7 As shown, the flow channel component 1100 consists of two independent but interconnectable parts. The first part is a rinsing arm 100, which is, for example, an L-shaped tubular structure, with one end connected to an external water source 3000 or an internal water source (such as a condensate collection device) of the laundry treatment device 2000, serving as the water inlet for the entire cleaning device 1000. The rinsing arm 100 has a first flow channel 101 formed inside. The second part is a plug 200, which has a second flow channel 201 formed inside. Here, the plug 200 is constructed as a shaft-like component that can pass through the through-hole 1210 at the center of the spray component 1200. In this way, the spray component 1200 can be rotatably fitted onto the plug 200. One end of the plug 200 is constructed to be connected to the end of the rinsing arm 100 (e.g., by snap-fit ​​or thread), so that the first flow channel 101 of the rinsing arm 100 can communicate with the second flow channel 201 of the plug 200. When the two are connected, they together form a complete and continuous first flow channel space 1110 (also as...). Figure 13 As shown, the cleaning medium can flow smoothly from the flushing arm 100 into the plug 200, then into the second flow channel space 1220 connected thereto, and finally out from the discharge opening 1230.

[0056] like Figures 5 to 7As shown, the rotatable spray component 1200 consists of two combinable half-shells 10 and 20. These two half-shells can be designed with matching positioning and connection structures. During production, they can be injection molded separately. Then, on an assembly line, the first half-shell 10 and the second half-shell 20 are joined together along the central axis 1211, and their joints are permanently fused together by welding. After welding, the two separate half-shells form the complete spray component 1200, naturally forming a second flow channel space 1220 for receiving and distributing water. Here, all the water discharge openings 1230 are located on the second half-shell 20 (here, the lower shell), which faces directly towards the filter 2100 to be cleaned. Figure 7 It can be seen that the first half-shell 10 has a first through hole 11 at its center, while the second half-shell 20 has a second through hole 21 at its center. When the two half-shells are welded together, these two coaxial through holes together form the through part 1210 of the spray component 1200, which is used to fit onto the plug 200.

[0057] from Figure 10 Combination Figure 7 It can be seen that the plug 200 has a closed bottom 220 on the side opposite to the flushing arm 100. From Figure 10 It can also be seen that a diversion structure 230 is provided near the closed bottom 220 of the plug 200. The function of this diversion structure 230 is to decompose the main water flow from above into multiple smaller diversions and guide them to flow out from the periphery of the plug 200 and into the second flow channel space 1220 of the spray member 1200 surrounding the plug. Figure 11 The diversion structure 230 achieves diversion through multiple dividing ribs 231, which are rotationally symmetrical with respect to the central axis 1211 and have a gradually increasing distance between adjacent dividing ribs 231 in a direction toward the radially outward.

[0058] Figure 14 It shows Figure 13 The enlarged view of part E shown.

[0059] like Figure 14 Combination Figure 13 as well as Figure 7As shown, after the flushing arm 100 and the plug 200 are connected to each other, the end of the flushing arm 100 forms a first end face 102 facing the spray member 1200. Simultaneously, the end of the plug 200 away from the flushing arm 100 also forms a second end face 202 facing the spray member 1200. The axial position of the spray member 1200 is thus defined between these two end faces. To achieve vibration and noise reduction, the cleaning device 1000 includes a first buffer 1001 and a second buffer 1002. The first buffer 1001 (e.g., a soft rubber gasket) is placed between the first end face 102 and the upper surface of the spray member 1200, and the second buffer 1002 (e.g., another soft rubber gasket) is placed between the second end face 202 and the lower surface of the spray member 1200. In this way, the rotatable spray member 1200 is axially clamped between these two soft buffers. When the vibration of the entire machine causes the spray component 1200 to move up and down along the axial direction (i.e., the direction of the central axis 1211), the spray component 1200 will first come into contact with one of the two buffer components. Since the buffer component is made of elastic materials such as rubber, it will absorb the impact energy through its own elastic deformation, transforming the hard impact sound into a dull, imperceptible contact, thereby achieving the purpose of vibration reduction and noise reduction.

[0060] like Figure 10 Combination Figure 14 As shown, an annular stepped surface 203 is provided on the outer wall of the plug 200. This stepped surface 203, together with the first end face 102 of the flushing arm 100, defines the mounting space for the first buffer member 1001. Below the stepped surface 203, extending to the second end face 202 of the plug 200, is the main body portion of the plug 200. The outer wall of this main body portion has a radial mounting distance d between it and the inner wall of the through portion 1210 of the spray member 1200, which is, for example, 0.1 mm to 0.2 mm. Figure 14 It can also be seen that the total axial height of the spray component 1200 is designed to be slightly less than the distance between the lower surface of the first buffer 1001 and the upper surface of the second buffer 1002. This means that, in the working state, a first axial gap a1 can exist between the spray component 1200 and the first buffer 1001, and a second axial gap a2 can exist between the spray component 1200 and the second buffer 1002. Here, the sum of a1 and a2 is, for example, in the range of 0.5 mm to 1 mm. Thus, on the one hand, the gap will not be too large to ensure sufficient water flow to drive the spray component 1200 to rotate normally, and the rotation position deviation is controllable; on the other hand, the gap will not be too small to ensure that water flow can flow out from the gap and wash away lint or debris inside the gap. Figure 7The diameter of the first through-hole 11 of the first half-shell 10 (the upper shell in this case) is greater than the inner diameter of the first buffer member 1001 but smaller than its outer diameter. Similarly, the diameter of the second through-hole 21 of the second half-shell 20 (the lower shell in this case) is greater than the inner diameter of the second buffer member 1002 but smaller than its outer diameter. This means that the first buffer member 1001 and the second buffer member 1002 can respectively cover the radial gap between the flow channel member 1100 and the spray member 1200, but will not get stuck in it.

[0061] Figure 15 It shows Figure 13 The image shown is a magnified view of part F.

[0062] like Figure 15 Combination Figure 13 As shown, the flushing arm 100 and the plug 200 are snapped together in the connection area 300. While this connection method is simple to assemble and low in cost, gaps inevitably exist between their mating surfaces. If these gaps are not addressed, water will leak significantly from the connection area 300 during operation, causing a substantial decrease in the amount and pressure of water entering the spray component 1200, severely affecting the spraying effect and rotation performance. Therefore, as... Figure 15 As shown, a sealed flow channel 310 is formed in the connection area 300 to restrict the flow of cleaning medium from the first flow channel space 1110. The sealed flow channel 310 can also be understood as a labyrinth seal structure. Figure 8 and Figure 9 Combination Figure 4 As shown, this labyrinthine sealing structure is formed by the interaction of the flushing arm 100 and the plug 200. Specifically, two concentric annular flanges extending towards the plug 200 are formed at the connecting end of the flushing arm 100: an inner flange 110 located on the inner side and an outer flange 120 located on the outer side. An annular groove is formed between these two flanges. A matching annular protrusion 210 is formed at the corresponding connecting end of the plug 200. During assembly, this protrusion 210 of the plug 200 can be inserted into the groove between the inner flange 110 and the outer flange 120 of the flushing arm 100, thereby forming a sealed flow channel 310. Figure 15As can be seen, the sealed flow channel 310 includes a first inlet section 311 at the inlet, which is connected to the first flow channel space 1110. Since the cleaning device 1000, when normally installed in the garment processing equipment 2000, has its central axis 1211 extending approximately vertically or slightly inclined, the water inlet is located at the top. The cleaning medium (water) flows downwards under gravity. To effectively prevent water leakage from the connection area 300, the first inlet section 311 of the sealed flow channel 310 is designed to have a flow component against gravity. This design, requiring the cleaning medium to flow upwards, increases the difficulty of leakage. Preferably, the sealed flow channel 310 also includes a second inlet section 312, which extends from the first inlet section 311 in a direction away from the spray member 1200, preferably parallel to the central axis 1211. In this way, the clean medium from the first flow channel space 1110 must undergo a slope-like anti-gravity movement to flow out of the sealed flow channel 310, thus making more effective use of gravity to impede the flow. In addition, by designing this second inlet section 312 to be relatively long, the path length can be significantly increased and the resistance can be improved, thereby reducing the total leakage.

[0063] from Figure 8 As can be seen, to ensure that the flushing arm 100 and the plug 200 are not only axially locked after being snapped together, but also circumferentially fixed (or can only be assembled at a specific angle), a specific protrusion and recess mating structure is adopted. P protrusions 211 are provided on the outer surface of the protruding edge 210 of the plug 200. In this embodiment, P = 2, that is, two protrusions 211 are symmetrically distributed on the outer periphery of the protruding edge 210. Correspondingly, P recesses 121 (two in this case) are formed on the outer flange 120 of the flushing arm 100. The position and shape of these recesses 121 match the protrusions 211 on the plug 200. During assembly, the plug 200 can be aligned with the flushing arm 100 first, so that the protrusions 211 and recesses 121 are aligned, and then the two are pressed together with force. During the pressing process, the protrusion 211 of the plug 200 causes a slight elastic deformation of the outer flange 120 of the flushing arm 100, allowing it to pass an interference point and engage with the recess 121. Once engaged, the edge of the protrusion 211 and the edge of the recess 121 mutually restrain each other, achieving locking in both the axial and circumferential directions. This design also serves as a Poka-yoke mechanism. For example, if the protrusion / recess shape is asymmetrical, the plug 200 can only be inserted into the flushing arm 100 at a unique angle, thus avoiding problems such as misalignment of internal flow channels due to incorrect assembly angles. P, being an integer greater than one, ensures at least two locking points, providing a more stable and reliable connection.

[0064] from Figure 8It can also be seen that, on the outer surface of the protruding edge 210 of the plug 200, in addition to the main snap-fit ​​protrusion 211, Q additional protrusions 212 are provided. In this embodiment, Q = 2, that is, two relatively small protrusions 212 are symmetrically arranged between the two protrusions 211. When the plug 200 is pressed into the flushing arm 100, the tips of these two protrusions 212 make line contact with the inner surface of the outer flange 120 of the flushing arm 100, thereby providing additional radial support points, making the positioning of the plug 200 inside the flushing arm 100 more stable and reducing shaking. Here, Q, as an integer greater than one, ensures that there are at least two such auxiliary support points, forming a more stable radial positioning. Also as... Figure 8 As shown, P protrusions 211 and Q protrusions 212 are evenly distributed with reference to the central axis 1211 and preferably alternately arranged on the outer side of the protrusion edge 210, thereby further improving the assembly stability of the product.
