[0002] With social development and the improvement of people's living standards, the popularity and usage of clothing processing equipment are increasing. Nowadays, drum washing machines, as a highly efficient and low-wear clothing processing device, have become an indispensable household appliance in people's daily lives.

[0003] Our conventional front-loading washing machines are equipped with an outer tub for holding water and an inner tub that uses tumbling and shaking motions to wash clothes. The area between the inner and outer tubs is a place that ordinary users cannot directly clean, making it easy for dirt and grime to accumulate. Over time, stains can adhere to the outer surface of the inner tub and the inner surface of the outer tub, forming deposits that can cause secondary contamination of clothes during subsequent use.

[0004] Existing drum washing machines typically have a dedicated drum cleaning program that users manually select and run without clothes inside. The inner drum is fully submerged in water and rotates to wash the drum, which not only wastes time and water resources but also requires manual intervention from the user and has limited cleaning effectiveness.

[0043] This utility model discloses a clothing processing device to solve the problem that existing washing machines cannot clean the area between the inner and outer drums, which easily accumulates dirt and causes secondary pollution to clothes.

[0044] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0046] In one specific embodiment, the clothing processing equipment provided in this application includes a box 1, and a drum assembly 2, a pumping device 3, a spraying device 4, and an ozone generator 51 device 5 located inside the box 1.

[0047] The bucket assembly 2 includes an outer bucket 21 and an inner bucket 22, with the inner bucket 22 located inside the outer bucket 21 and a sandwich layer between them;

[0048] One end of the pumping device 3 is connected to the outer tank 21 to extract water from the interlayer, and the other end of the pumping device 3 is connected to the spraying device 4.

[0049] The ozone generator 51 device 5 is located inside the housing 1, and one end is connected to the spray device 4 for treating water.

[0050] The spray device 4 is located between the layers and is used to rinse the inner tub 22 and / or the outer tub 21.

[0051] In one embodiment, the housing 1 serves as a supporting and protective outer shell, internally integrating a washing and rinsing unit 3, a spraying unit 4, and an ozone generator 51. Integrating multiple functional modules within the same housing 1 results in a compact structure that facilitates installation and maintenance. This achieves integrated washing, rinsing, and sterilization operations, enhancing the equipment's intelligence and automation level. The ozone generator 51 enhances the equipment's health care functions, effectively killing bacteria and viruses and reducing reliance on chemical detergents.

[0052] The outer tub 21 is fixed inside the housing 1 and is usually stationary. It is used to hold washing water and support the inner tub 22. The inner tub 22 is located inside the outer tub 21 and has a dewatering hole for holding clothes. It rotates at a low speed during washing and at a high speed during dewatering. The interlayer is the annular space between the inner wall of the outer tub 21 and the outer wall of the inner tub 22.

[0053] The inlet end of the pumping device 3 is connected to the outer tub 21, preferably to the lower part or bottom of the interlayer, so as to extract water (which may be residual washing water, condensate water or specially injected cleaning water) from the interlayer; the outlet end is connected to the spraying device 4, and the extracted water is pressurized and delivered to the spraying device 4; the water is recycled, which is not simply draining water, but extracting water from the interlayer, treating it and reusing it for rinsing, thereby improving the efficiency of water resource utilization.

[0054] When the equipment starts its self-cleaning program, the pumping device 3 starts, drawing water from the bottom of the interlayer. After the water is pressurized, it is transported to the spraying device 4 through pipelines. The water is recycled, reducing dependence on external water sources and wastewater discharge. Stable pressure is provided to ensure that the spraying has sufficient impact force to remove dirt.

[0055] Ozone generator 51 is a device that ionizes oxygen (O2) in the air to generate ozone (O3). Ozone is a strong oxidant with extremely strong bactericidal, disinfecting, and deodorizing capabilities. Ozone generator 51 is located inside housing 1 for easy integration and wiring. One end of ozone generator 51 is connected to spray device 4, and ozone gas is injected into the water flowing towards spray device 4. If a Venturi jet or static mixer is used, the water to be sprayed is "activated," making it "ozone water" with bactericidal and disinfecting functions. It can be understood that ozone decomposes back into oxygen, leaving no harmful residues like chemical disinfectants, making it more environmentally friendly and safer; it can effectively kill bacteria, viruses, mold, and other microorganisms; and it can decompose organic molecules that produce odors, thoroughly removing musty and sour smells.

[0056] By incorporating an ozone generator 51 device 5, not only physical rinsing is achieved, but also deep purification at the chemical / biological level, realizing a dual cleaning approach of "physical + chemical." This effectively solves the problem of "secondary pollution" caused by mold growth on the tank, protecting user health.

[0057] The spray device 4 is located within the interlayer space and can directly spray water onto the outer wall of the inner tub 22, the inner wall of the outer tub 21, and the surface of the interlayer itself. It receives ozone-containing water from the pumping device 3 and sprays it out at a certain pressure and angle, forming a water curtain or column to rinse various surfaces in the interlayer area. In one embodiment, multiple fixed nozzles are installed at different heights and angles within the interlayer for comprehensive coverage. Rinsing the outer wall of the inner tub removes dirt and fibers adhering to the outer surface of the inner tub 22; rinsing the inner wall of the outer tub 21 cleans its inner surface; and rinsing the interlayer space washes away dirt deposited at the bottom of the interlayer. The spray device 4 is deployed directly inside the pollution source, achieving source control, and its cleaning effect far exceeds that of external spraying or soaking. Through a reasonable nozzle layout or a rotating design, it ensures that all areas within the interlayer are rinsed by the water flow. The user only needs to start the program to complete the entire cleaning process without manual intervention.

[0058] In one embodiment, the pumping device 3 includes a booster pump 31, a drainage pipe 32, and a pumping pipe 33;

[0059] One end of the drainage pipe 32 is connected to the mezzanine, and the other end of the drainage pipe 32 is connected to one end of the booster pump 31. The other end of the booster pump 31 is connected to the pumping pipe 33, and the pumping pipe 33 is connected to the spraying device 4.

[0060] One end of the drain pipe 32 connects to the interlayer, typically to the bottom of the outer tank 21 or the lowest point of the interlayer, ensuring that most of the accumulated water can be pumped out. A filter screen can be installed at the connection to prevent large particles from entering the pipe. The other end connects to one end of the booster pump 31, serving as the inlet 422 of the booster pump 31. The drain pipe 32 "transports" water from the interlayer to the inlet of the booster pump 31, thus achieving water collection and transportation. It is the starting point of the entire circulation system, responsible for drawing the water to be treated out of the contaminated area (interlayer). In one embodiment, a one-way valve is added to the drain pipe 32 to prevent water from flowing back into the interlayer when the pump is stopped. Furthermore, a filter is installed before the pump to protect the impeller of the booster pump 31. The other end of the booster pump 31 is the outlet of the booster pump 31, and the water pumping pipe 33 is the outlet pipe of the water flow, which is responsible for transporting the water pressurized by the booster pump 31 to the spraying device 4. The outlet of the booster pump 31 is directly connected to one end of the water pumping pipe 33 to realize the pressurization and output of the water. The booster pump 31 provides sufficient pressure for the water flow so that it can generate effective flushing force through the subsequent ozone mixing and spraying process.

[0061] The other end of the pumping pipe 33 is finally connected to the inlet 422 of the spray device 4, forming a complete physical fluid channel: interlayer → drainage pipe 32 → booster pump 31 (inlet 422) → booster pump 31 (outlet) → pumping pipe 33 → spray device 4.

[0062] The specific workflow is as follows: the self-cleaning program is started; the booster pump 31 starts working and forms a negative pressure at its inlet 422; the water in the interlayer is drawn into the booster pump 31 through the drain pipe 32 under atmospheric pressure; the booster pump 31 pressurizes the water; the pressurized water is pumped out through the pumping pipe 33 and flows to the spray device 4; the water mixes with the ozone generated by the ozone generator 51 on its way to the spray device 4 to form ozone water; the ozone water reaches the spray device 4 and is sprayed out to rinse the interlayer area.

[0063] Specifically, the spray device 4 is located at the top of the tank assembly 2; the water pumping pipe 33 extends along the inner wall of the tank 1 to the top of the tank assembly 2 and is connected to the spray device 4.

[0064] The spray device 4 is placed at the top, preferably fixed to the outer wall of the outer barrel 21, so that the water sprayed can flow downwards by gravity, naturally covering the outer wall of the inner barrel 22, the inner wall of the outer barrel 21, and the entire interlayer space; making full use of gravitational potential energy to enhance the rinsing effect; the water sprayed from a height can form a "waterfall-like" or "rain-like" rinsing effect, achieving a thorough and complete rinsing of the interlayer area, especially effectively flushing the sediment at the bottom of the interlayer. The top area typically has no rotating parts during equipment operation (the rotation axis of the inner barrel 22 is at the bottom), so installing the spray device 4 here will not interfere with the high-speed rotation of the inner barrel 22, ensuring the safety and stability of the equipment; compared to burying the spray device 4 deep inside the interlayer, top installation makes it easier to inspect, replace, or clean the nozzles. Preferably, an annular pipe is installed on the inner side of the top of the barrel assembly 2, with multiple downward-spraying nozzles evenly distributed on the pipe; or one or more nozzles are installed at the top of the central axis of the barrel assembly 2 to spray downwards.

[0065] The water pumping pipe 33 runs along the inner wall of the equipment casing, ending at the top of the tank assembly 2, where it connects with the spray device 4. The internal space of the equipment is compact, with various components (motors, shock absorbers, counterweights, wiring harnesses, etc.) densely packed. Running the pipe along the inner wall maximizes the use of unused space, avoids interference with other components, and makes the internal layout neater and more compact. Running the pipe along the wall reduces the risk of collision or wear from other moving parts (such as counterweights and shock absorbers) during equipment operation (e.g., vibration, handling). Neat wiring improves the internal craftsmanship and aesthetics of the equipment and facilitates standardized production. Fixing the pipe to the rigid side wall of the housing 1 reduces its own vibration, lowering the risk of noise and fatigue damage.

[0066] In one alternative embodiment, the spray device 4 includes:

[0067] The spray pipe 41 and the spray box 42 are connected. The spray pipe 41 extends along the outer wall of the barrel assembly 2. The spray box 42 has several spray holes 421.

[0068] The spray pipe 41 is the main pipeline for transporting water, delivering water from the pumping device 3 to each spray point. The spray box is a cavity structure connected to the spray pipe 41, and may have an internal flow guiding structure and integrate multiple spray holes 421; it is usually made of corrosion-resistant and aging-resistant engineering plastics (such as PP, ABS) or stainless steel; it can be manufactured by injection molding, extrusion or machining.

[0069] The spray pipe 41 is attached to or fixed to the outer surface of the tank assembly 2, and can extend in a straight line, a ring, or be designed into a specific path as needed. By arranging the pipe on the outer wall, installation, maintenance, or replacement can be carried out without disassembling the internal structure of the tank, greatly reducing maintenance difficulty and cost; it completely avoids the complex mechanical structure inside the tank (such as bearings, seals, shock absorbers, etc.), the installation process is simple and will not affect other components.

[0070] The spray box 42 is connected to the main spray pipe 41 via direct connection (such as snap-fit, thread, welding) or branch pipes to ensure that water can enter the box from the pipes. The spray box 42 may have a guide plate or a flow distribution cavity inside to ensure that the water can be evenly distributed to each spray hole 421. The spray holes 421 are small holes machined on the surface of the spray box 42. Water is sprayed out through these holes. The direction of the spray holes 421 can be designed to be obliquely downward, horizontal, or at a specific angle to ensure that the water can accurately enter the interlayer and wash the target surface.

[0071] The pressurized water flows from the pumping device 3 through the pipeline to the spray pipeline 41. The water flows into the spray box 42 through the connection point. The water is distributed to each spray hole 421 in the box. The water is sprayed out at high speed from the spray hole 421 and enters the interlayer in the form of multiple water columns or water curtains to wash the outer wall of the inner barrel 22, the inner wall of the outer barrel 21 and the interlayer space.

[0072] Specifically, the spray box 42 has an elongated structure; the spray nozzles 421 also have elongated structures. The elongated structure allows it to extend continuously along the height or circumference of the tank, thus achieving linear flushing of the interlayer area, effectively eliminating flushing blind spots, and ensuring that the entire target area is covered by water flow. The elongated design facilitates connection with the similarly linearly extending spray pipes 41, allowing for direct connection, snap-fit ​​fixing, or screw installation, making assembly simple and reliable. As an elongated cavity, the spray box 42 has a relatively uniform internal water pressure distribution, contributing to stable water output along its length.

[0073] The water jet from the strip-shaped orifice naturally spreads out, forming a flat, fan-shaped water curtain or sheet-like jet, rather than a solid, round water column. This type of water flow has a larger coverage area, capable of simultaneously cleaning a wider surface area, resulting in higher cleaning efficiency. Compared to small round orifices, the strip-shaped orifice has a larger effective flow cross-section, and impurities along its length are more easily washed away by the water flow. Therefore, it is less likely to be completely clogged by fibers, hair, and other debris, improving the system's reliability. The fan-shaped water curtain has a relatively uniform pressure distribution, and the impact force is gentler than a concentrated water column, effectively removing dirt while reducing damage to the tank surface or excessive noise.

[0074] In one alternative embodiment, the spray box 42 has a water inlet 422 and an ozone inlet 423, which are located on one side of the length direction of the spray box 42.

[0075] The water inlet 422 is used to connect to the pumping pipe 33 from the pumping device 3 to introduce pressurized water; the ozone inlet 423 is used to connect to the ozone delivery pipe 52 from the ozone generator 51 device 5 to introduce high-concentration ozone (O3); integrating both water and ozone inlets into the spray box 42 simplifies the system structure; the centralized arrangement allows the pumping pipe 33 and ozone pipe from inside the equipment to be connected to the spray box 42 at the same location; this greatly facilitates on-site installation, wiring, and sealing; the centralized interfaces and sealing points make it easier to perform effective sealing treatment (such as using porous gaskets or quick-connect fittings), reducing the risk of water and ozone leakage.

[0076] Furthermore, the tank assembly 2 is arranged in a horizontal direction; the spray pipe 41 extends along the axial direction of the tank assembly 2.

[0077] The tub assembly 2 is arranged horizontally, preferably in a drum washing machine, with the axial direction being the direction of the rotation axis of the tub assembly 2. The spray pipe 41 is arranged parallel to the axial direction, and the axially extending pipe can cover the entire length of the tub assembly 2, ensuring that the entire interlayer area from the front end to the rear end of the tub can be rinsed, avoiding cleaning blind spots. In one embodiment, one or more spray boxes 42 can be installed on the axially extending spray pipe 41. The spray box 42 has a long strip structure, forming a continuous rinsing band parallel to the pipe.

[0078] Based on the above embodiments, the ozone generator 51 device 5 includes:

[0079] The ozone generator 51, the ozone delivery pipeline 52, and the control valve 53 are included. One end of the ozone delivery pipeline 52 is connected to the ozone generator 51, and the other end is connected to the spray device 4. The control valve 53 is located between the ozone generator 51 and the ozone delivery pipeline 52 and is used to control the on / off state of the pipeline.

[0080] The ozone generator 51 converts oxygen (O2) in the air into ozone (O3) through high-voltage corona discharge or ultraviolet irradiation. It typically includes core components such as a high-voltage power supply and a discharge chamber. The ozone delivery pipeline 52, made of ozone-resistant materials (such as Teflon, silicone, or stainless steel), safely and leak-free delivers the generated ozone gas from the generator to the spray device 4. The control valve 53 controls the on / off flow of the ozone gas. It can be a solenoid valve, an electric valve, etc. The control valve 53 is installed between the outlet of the ozone generator 51 and the inlet of the ozone delivery pipeline 52, acting as a switch to precisely control when the ozone gas delivery begins and stops. In one embodiment, the control valve 53 is a one-way valve.

[0081] Normal flow (on):

[0082] When the ozone generator 51 is working and generates positive pressure, the airflow flows from the ozone generator 51 end to the ozone delivery pipeline 52 end; the airflow pressure overcomes the spring force or gravity inside the one-way valve, pushes open the valve disc (or diaphragm), and the valve automatically opens to allow ozone gas to pass through.

[0083] Reverse flow (closed):

[0084] When ozone generator 51 stops working, or when the pressure in the delivery pipeline is higher than that at the generator end (e.g., water backflow, change in external air pressure), reverse pressure will be generated.

[0085] At this point, the reverse pressure will press the valve disc (or diaphragm) tightly against the valve seat, and the valve will automatically close, forming a seal and completely blocking the reverse flow of gas.

[0086] The specific workflow is as follows:

[0087] Standby state: Control valve 53 is closed, so even if ozone generator 51 is working, ozone cannot enter the delivery pipeline, preventing unnecessary consumption and potential leakage;

[0088] Initiating mixing: When the system needs to generate ozone water (for example, when pumping device 3 starts working and water flows to the vicinity of spraying device 4), the main control board issues a command to open control valve 53;

[0089] Ozone delivery: Ozone gas flows out from the generator, passes through the open control valve 53, and enters the spray device 4 (or the pipeline that mixes with the water flow) through the delivery pipeline.

[0090] Stop supply: When the self-cleaning process ends or needs to be paused, the main control board closes control valve 53 to immediately cut off the ozone supply.

[0091] This allows for the on-demand distribution of ozone supply. Ozone is only delivered when needed, avoiding waste and equipment damage caused by continuous emissions.

[0092] In one alternative embodiment, the garment handling device is a drum washing machine or a top-loading washing machine.

[0093] Example 2

[0094] This application may also include a silver ion storage device located between the pumping device and the spraying device; one end of the pumping device is connected to the outer tank for extracting water from the interlayer, the other end of the pumping device is connected to one end of the silver ion storage device, and the other end of the silver ion storage device is connected to the spraying device.

[0095] When the equipment initiates its self-cleaning process, the pumping unit starts, drawing water from the bottom of the jacket. The pressurized water is then transported through pipelines to the silver ion storage device. Inside the silver ion storage device, the water comes into contact with the silver material, and silver ions (Ag) are released into the storage medium. + The silver ions are released and dissolved in the water; the water rich in silver ions flows out from the silver ion storage device and enters the spray device; the water containing silver ions is sprayed out by the spray device to rinse the interlayer area.

[0096] Silver ions possess powerful antibacterial properties, effectively killing various bacteria, fungi, and some viruses. Unlike the "instantaneous and potent" effect of ozone, silver ions have a longer-lasting effect and may remain on the surface of the container even after cleaning, providing a certain degree of long-lasting antibacterial protection.

[0097] The spraying device is located within the interlayer space and can directly spray water onto the outer wall of the inner tub, the inner wall of the outer tub, and the surface of the interlayer itself. It receives water (containing silver ions) from a pumping device and sprays it out at a certain pressure and angle, forming a water curtain or column to rinse all surfaces of the interlayer area. In one embodiment, multiple fixed nozzles are installed at different heights and angles within the interlayer for comprehensive coverage. Rinsing the outer wall of the inner tub removes dirt and fibers adhering to its outer surface; rinsing the inner wall of the outer tub cleans its inner surface; and rinsing the interlayer space washes away dirt deposited at the bottom of the interlayer. The spraying device is deployed directly inside the pollution source, achieving source control, and its cleaning effect far surpasses external spraying or soaking. Through a reasonable nozzle layout or a rotating design, it ensures that all areas within the interlayer are rinsed by the water flow. Users only need to start the program to complete the entire cleaning process without manual intervention.

[0098] In one embodiment, the pumping device includes a booster pump, a drain line, and a pumping line;

[0099] One end of the drainage pipe is connected to the interlayer, the other end of the drainage pipe is connected to one end of the booster pump, the other end of the booster pump is connected to the pumping pipe, and the pumping pipe is connected to the silver ion storage device.

[0100] One end of the drain pipe connects to the mezzanine, typically to the bottom of the outer tank or the lowest point of the mezzanine, ensuring that most of the accumulated water can be pumped out. A filter screen can be installed at the connection to prevent large particles from entering the pipe. The other end connects to one end of the booster pump, serving as the pump's inlet. The drain pipe "transports" water from the mezzanine to the booster pump's inlet, thus achieving water collection and transportation. It is the starting point of the entire circulation system, responsible for drawing the water to be treated out of the contaminated area (mezzanine). In one embodiment, a check valve is added to the drain pipe to prevent water from flowing back into the mezzanine when the pump is stopped; furthermore, a filter is installed before the pump to protect the booster pump impeller. The other end of the booster pump is the pump outlet, and the pumping pipe is the water outlet pipe, responsible for transporting the water pressurized by the booster pump to the silver ion storage device. The pump outlet is directly connected to one end of the pumping pipe to realize the pressurization and output of the water. The booster pump provides sufficient pressure to the water flow so that it can generate effective flushing force through the subsequent ozone mixing and spraying process.

[0101] The other end of the pumping pipeline is finally connected to the silver ion storage device, forming a complete physical fluid channel: interlayer → drainage pipeline → booster pump (inlet) → booster pump (outlet) → pumping pipeline → silver ion storage device → spraying device.

[0102] The specific workflow is as follows: the self-cleaning program is activated; the booster pump operates, drawing water from the interlayer through the drain pipe; the water is pressurized within the booster pump; the pressurized water is pumped out through the pumping pipe, first entering the silver ion storage device; inside the silver ion storage device, the water comes into contact with the silver material, and silver ions (Ag)... + The silver ions dissolve and are released into the water, forming "water containing silver ions". The water rich in silver ions flows out from the silver ion storage device and flows to the spray device. The water containing silver ions is sprayed out by the spray device to rinse the interlayer area.

[0103] In one embodiment, the storage box is a sealed container, typically made of corrosion-resistant and aging-resistant materials (such as food-grade plastic or stainless steel). The storage box has an internal cavity into which solid silver material (such as silver rods, silver sheets, silver-loaded ceramic balls, silver-loaded activated carbon, etc.) is placed. When water flows through it, the silver atoms on the surface of the silver material lose electrons to form silver ions (Ag). + The water enters the water; the inlet and outlet form a channel for water flow through the storage box, ensuring that all water must flow through the hollow cavity. The inlet and outlet are connected to the interior of the hollow cavity. Water enters from the inlet and flows into the hollow cavity; after contacting the silver material inside the cavity, it flows out from the outlet. The other end of the inlet is connected to the pumping pipe of the pumping device to receive and pressurize the water drawn from the jacket; the other end of the outlet is connected to the inlet of the spray device to deliver the silver-ion-rich water to the spray device.

[0104] The specific workflow is as follows: the pumping device draws water from the interlayer, pressurizes it, and sends it through pipelines to the inlet of the storage box; the water flows into the hollow cavity and comes into full contact with the silver material (such as a silver rod) inside the cavity; under the scouring of the water flow and electrochemical action, silver ions (Ag) are released from the surface of the silver material. + The silver ions dissolve in the water; the water rich in silver ions flows out from the outlet and into the spray device; the spray device sprays out the water containing silver ions to rinse the interlayer area, achieving physical cleaning and chemical sterilization.

[0105] The storage box, as an independent functional module or consumable, can be designed as a detachable and replaceable structure. When the silver material is depleted or reaches the end of its service life, users can easily replace it with a new storage box without replacing the entire system. The hollow cavity provides ample space and time for the water flow to contact the silver material. By designing the flow channels inside the cavity (such as spirals and baffles), the hydraulic residence time can be extended, increasing turbulence and maximizing the release efficiency of silver ions. Enclosing the silver material within the storage box prevents silver particles or other materials from directly entering the water flow and being washed onto clothing, ensuring the safety and cleanliness of the washing process.

[0106] Preferably, the storage box includes:

[0107] The box body and the top cover form a hollow cavity, and the box body and the top cover are detachably and fixedly connected.

[0108] The main body of the storage box contains the silver material. The top cover is the upper or closed part of the storage box, used to seal the opening of the box. When the top cover and the box are combined, they form a closed internal space, namely a hollow cavity, for placing the silver material and for water treatment. The box and the top cover can be connected by threads, snaps, etc. When the silver material (such as silver rods or silver balls) is exhausted, its activity decreases, or it reaches the end of its service life, the user can remove the top cover, take out the old silver material, put in the new silver material, and then reinstall the top cover. After long-term use, scale or impurities may accumulate on the inner wall of the hollow cavity or on the surface of the silver material. After removing the top cover, the inside of the cavity and the silver material can be easily cleaned and maintained to ensure the continuous and effective release of silver ions.

[0109] Furthermore, the storage box is detachably fixed to the body; fasteners such as screws or bolts are used to facilitate disassembly and maintenance, allowing users or maintenance personnel to easily remove and reinstall it when needed; when the silver material needs to be replaced (even if the top cover is removable, sometimes it is more convenient to replace the whole thing) or when the entire storage box reaches the end of its service life, the user does not need to open the washing machine shell or perform complicated operations.

[0110] In one embodiment, the booster pump is an electric vane centrifugal booster pump or an electric reciprocating plunger booster pump. The electric vane centrifugal booster pump provides a continuous and stable water flow with minimal pulsation; it also has low noise and relatively smooth operation with good noise control. The electric reciprocating plunger booster pump can generate very high pressure, making it suitable for scenarios requiring powerful flushing; it has good self-priming performance and can start even if there is air in the pipeline. The booster pump can be selected as needed, and all of these are within the scope of protection of this application.
