[0051] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0052] Please see Figure 1This embodiment provides a washing machine 100, a household appliance used for automatically washing clothes. It uses electrical energy to drive mechanical parts to move, and combined with the action of chemical detergents, effectively removes stains and odors from clothes. The washing machine 100 includes a drum assembly 10 and a water inlet pipe 20. The drum assembly 10 holds the clothes to be washed and the washing water. During the washing process, the drum assembly 10 rotates under the drive of a motor, generating mechanical force. Combined with the water flow and the action of the laundry detergent, this effectively cleans the clothes. The water inlet pipe 20 is connected to the drum assembly 10 and is used to connect to an external water source, introducing washing water into the drum assembly 10 to ensure a sufficient water supply during the washing process.

[0053] Furthermore, the washing machine 100 also includes an electrolytic cleaning device 30 and a slow-release cleaning device 40. The electrolytic cleaning device 30 is connected to the water inlet pipe 20 and is used to electrolyze the water in the water inlet pipe 20 to generate electrolyzed cleaning substances, which are then supplied to the drum assembly 10. That is, the water in the water inlet pipe 20 can flow into the drum assembly 10 after passing through the electrolytic cleaning device 30. The electrolytic cleaning device 30 can treat the water flowing from the water inlet pipe 20 using the principle of electrolysis. During the electrolysis process, water molecules are decomposed into hydrogen ions and hydroxide ions. In the cathode area, the concentration of hydroxide ions increases, thereby producing alkaline water. Alkaline water has a good cleaning effect, can neutralize acidic stains, and has a peeling effect on certain types of dirt. Therefore, after treatment by the electrolytic cleaning device 30, electrolyzed water with a cleaning effect can be generated, enhancing the cleaning ability of the washing water flowing into the drum assembly 10, thereby improving the washing effect of the washing machine 100 on clothes.

[0054] In one configuration, the electrolytic cleaning device 30 uses inert electrodes (such as platinum, iridium, graphite, etc.) as the anode to reduce oxidation and wear of the electrodes themselves. These materials do not react with oxygen, allowing oxygen to accumulate on the electrode surface and react with water to form hydrogen peroxide. Furthermore, the stability of hydrogen peroxide increases under alkaline or neutral conditions (high pH), thus favoring its formation and accumulation. Hydrogen peroxide is a strong oxidizing agent widely used for disinfection and bleaching. During electrolysis, water molecules lose electrons at the anode to generate oxygen (O2), which can then react with hydrogen ions in the water to produce hydrogen peroxide. The generation of hydrogen peroxide enhances the cleaning and disinfecting capabilities of the washing machine 100, especially in situations where high temperatures are not required.

[0055] Please see Figure 2 and Figure 3Specifically, the electrolytic cleaning device 30 is a hydrogen peroxide generator. The hydrogen peroxide generator includes a main shell 31 and an inlet 31a and an outlet 31b disposed on the main shell 31. The inlet 31a is used to connect to the water inlet pipe 20. The main shell 31 is provided with a cathode plate 32 and an anode plate 33 for electrolyzing water to generate hydrogen peroxide solution. The outlet 31b is used to discharge the generated hydrogen peroxide solution.

[0056] In other words, water from the inlet pipe 20 enters the main casing 31 through the liquid inlet 31a, and is electrolyzed into hydrogen peroxide by the cathode plate 32 and anode plate 33 inside the main casing 31. The hydrogen peroxide solution produced by electrolysis is discharged from the main casing 31 through the drain port 31b. Hydrogen peroxide solution has good cleaning, deodorizing, disinfecting and sterilizing functions. Therefore, when this hydrogen peroxide generator is applied to the washing machine 100, it can play a good role in cleaning, deodorizing, disinfecting and sterilizing.

[0057] Specifically, when the hydrogen peroxide generator is applied to the washing machine 100, it can clean the clothes with reduced or even no detergent usage, enhance the washing effect, reduce detergent consumption, achieve low carbon emissions and environmental protection, and eliminate the need for users to frequently add detergent to the washing chamber 10a. When the hydrogen peroxide generator is applied to other household appliances (such as dryers, clothes care cabinets, refrigerators, air conditioners, dehumidifiers, etc.), it can effectively remove odors, ensure air cleanliness, and thus improve the user experience.

[0058] In a specific implementation, the hydrogen peroxide generator is installed in the washing machine 100. The inlet 31a and outlet 31b of the hydrogen peroxide generator can be connected to the liquid pipeline already present in the washing machine 100, or to a liquid pipeline additionally provided to the washing machine 100 for connecting the hydrogen peroxide generator. Alternatively, the inlet 31a of the hydrogen peroxide generator can be at least partially immersed in the washing water, thereby realizing the generation of hydrogen peroxide solution by electrolyzing water using the hydrogen peroxide generator, thereby improving the cleaning ability of the washing machine 100 by using the hydrogen peroxide solution.

[0059] Please continue reading. Figure 2 and Figure 3In some embodiments, the main shell 31 includes a first main shell portion 311 and a second main shell portion 312 connected to each other. An electrolysis chamber is formed between the first main shell portion 311 and the second main shell portion 312. A middle frame 313 is disposed in the electrolysis chamber. A cathode plate 32 is disposed between the first main shell portion 311 and the middle frame 313, and between the second main shell portion 312 and the middle frame 313. That is, the middle frame 313 is disposed between the cathode plate 32 and the anode plate 33, so that there is a certain distance between the cathode plate 32 and the anode plate 33. With this arrangement, water can enter between the cathode plate 32 and the anode plate 33, thereby ensuring that both the cathode plate 32 and the anode plate 33 can contact water, so as to ensure the electrolysis effect of the hydrogen peroxide generator.

[0060] The first main shell 311 and the second main shell 312 can be fixed by means of snap-fit, magnetic attraction, thread, etc., and this application does not limit this. In addition, sealing gaskets 34 can be provided between each pair of the first main shell 311, the middle frame 313, and the second main shell 312 to isolate the outside air from the electrolysis chamber.

[0061] The cathode plate 32 has a flat plate structure to isolate it from external air and the electrolytic chamber. Specifically, the cathode plate 32 includes a first metal substrate and a conductive carbon substrate layer coated on the surface of the first metal substrate. The first metal substrate can be selected from any one or a combination of at least two of platinum mesh, nickel mesh, or stainless steel mesh. The conductive carbon substrate layer is composed of carbon materials, preferably carbon black or carbon-doped materials.

[0062] In a practical implementation, a conductive carbon-based material can be coated onto the surface of a first metal substrate and pressed to form a three-phase gas diffusion electrode. The gas diffusion electrode possesses highly efficient gas molecule transport channels and abundant hydrogen peroxide reaction sites. Oxygen molecules in the air pass through the electrode sheet and gain electrons on the other side to produce hydrogen peroxide. Specifically, the cathode chemical reaction is: O2 + 2H2O + 4e- → 2H2O2. Therefore, the cathode sheet 32 ​​needs to be in contact with air on one side and with the electrolyte on the other.

[0063] In some embodiments, the anode sheet 33 has a flat plate structure, a mesh structure, or a porous structure. Specifically, the anode sheet 33 includes a second metal substrate and a transition metal coating with catalytic activity coated on the surface of the second metal substrate. The second metal substrate is made of any one or a combination of at least two of titanium, nickel, or platinum, and the transition metal coating is composed of any one or a combination of at least two of ruthenium, iridium, tantalum, palladium, or their oxides. Exemplarily, the anode sheet 33 has a porous structure, wherein the shape of the pores can be any shape, such as circular, square, or irregular, and the number can be specifically set according to actual needs; this disclosure does not limit this. Specifically, the thickness of the anode sheet 33 is not less than 0.5 mm. The anode chemical reaction formula is: 4OH-→O2+2H2O+4e-.

[0064] It is understandable that when the anode plate 33 is a flat plate structure, the electrolysis chamber is a cavity structure formed between the cathode plate 32 and the anode plate 33. When the anode plate 33 is a mesh plate structure or a porous structure, the electrolysis chamber is a cavity structure formed between the cathode plate 32 and the second main shell 312. Water can pass through the anode plate 33 and flow in the electrolysis chamber, thereby ensuring that the shape of the anode plate 33 can be specifically set according to actual needs.

[0065] It should be noted that, in specific implementation, both the anode plate 33 and the cathode plate 32 need to be connected to a DC power supply. The DC power supply is located outside the main housing 31 of the hydrogen peroxide generator so as to provide electron supply to the anode plate 33 and the cathode plate 32 through the DC power supply, and the current is controlled between 0-10A.

[0066] It should also be noted that the number of cathode plates 32 and anode plates 33 provided inside the main shell 31 is not limited to one; two, three, or more can be provided as needed.

[0067] Please see Figure 1 and Figure 4 The slow-release cleaning device 40 is also connected to the water inlet pipe 20. The slow-release cleaning device 40 is used to dissolve water in the water inlet pipe 20 to generate a slow-release cleaning substance and supply it to the drum assembly 10. Water in the water inlet pipe 20 can flow into the drum assembly 10 after passing through the slow-release cleaning device 40. The slow-release cleaning device 40 includes a slow-release body 43, which can dissolve in water to generate a slow-release cleaning substance. In this embodiment, the cleaning substance is a detergent. As in other embodiments, the slow-release body 43 may also include at least one of the following: a bactericide, a fabric softener, a fragrance, an anti-wrinkle agent, an anti-color bleeding agent, a color fixing agent, a deodorizer, a solid enzyme preparation, a water softener, and a descaling agent, which can be used in conjunction with the detergent.

[0068] It should be noted that the aforementioned slow-release agent 43 is a novel form of detergent. Slow-release agent 43 comprises a binder, water-soluble polymers, and surfactants. The binder, such as low molecular weight resins (polyethylene wax, terpene resins, petroleum resins, etc.), binds the components of slow-release agent 43 together, ensuring its stability during storage and use. Water-soluble polymers, such as polyvinyl alcohol, polyethylene glycol, and polyethylene oxide, dissolve rapidly in water, promoting detergent release. Surfactants, including nonionic, anionic, cationic, and amphoteric surfactants, provide strong detergency. Since surfactants dissolve in water, the formulation and structure of slow-release agent 43 are designed to dissolve gradually in water, rather than completely dissolving all at once. This controlled dissolution characteristic allows only the required amount of detergent to be used in each wash, while reserving residual slow-release agent 43 for subsequent use. During each wash, slow-release agent 43 dissolves only an appropriate amount of surfactant and other cleaning ingredients to meet the needs of the current wash cycle. The chemical composition of the slow-release agent 43 remains stable during storage and use, maintaining its form and efficacy even after multiple washes. This stability ensures that the slow-release agent 43 continues to release an appropriate amount of detergent during the next wash. This appropriate release ensures effective washing while preventing excessive detergent use. With the slow-release cleaning device 40, the washing machine 100 no longer requires an additional pump to extract laundry detergent, significantly reducing the frequency of detergent application and providing consistent washing results.

[0069] The sustained-release agent 43 contains 15-25 parts of binder, 15-25 parts of water-soluble polymer material, and 50-70 parts of surfactant. The specific amounts can be set by those skilled in the art according to their needs.

[0070] The washing machine 100 includes an electrolytic cleaning device 30 and a slow-release cleaning device 40. Because the slow-release cleaning device 40 automatically releases a slow-release cleaning substance upon contact with water, it reduces user intervention, simplifies the user experience of using the washing machine 100, and offers a high degree of automation, strong washing effect, and appropriately shortens washing time. The electrolytic cleaning substance produced by the electrolytic cleaning device 30 and the slow-release cleaning substance produced by the slow-release cleaning device 40 work together to improve the cleanliness of the clothes washed by the drum assembly 10. The improved washing efficiency is due to the elimination of the time required for the user to add detergent, and the electrolytic cleaning device 30 enhances the water's cleaning ability. To achieve the same washing effect, this embodiment shortens the overall washing time compared to washing equipment in related technologies.

[0071] Specifically, the water inlet pipe 20 includes an inlet valve (not shown), which controls the opening and closing of the external water flow to ensure that the washing machine 100 can accurately fill with water when needed and to control the water flow rate to meet the water requirements of different washing programs. The inlet valve also prevents backflow and protects the structure located upstream of the inlet valve along the water flow direction from damage.

[0072] Furthermore, both the electrolytic cleaning device 30 and the slow-release cleaning device 40 are located between the water inlet valve and the drum assembly 10, which ensures that the water is effectively treated before entering the washing drum, improving washing efficiency, simplifying user operation, and facilitating equipment maintenance and management.

[0073] Please see Figure 5 In one configuration, the inlet valve, electrolytic cleaning device 30, slow-release cleaning device 40, and drum assembly 10 are sequentially connected, forming a series water treatment process. First, the inlet valve controls the water flow. Then, the water is ionized by the electrolytic cleaning device 30, producing oxidizing active substances that help to initially decompose substances. Next, the water flows into the slow-release cleaning device 40, where the slowly released detergent further enhances the water's cleaning power. Finally, the treated water enters the drum assembly 10 for deep cleaning of clothes. In this series flow path, each portion of the water undergoes the same treatment process, ensuring uniform water quality and consistent treatment. Furthermore, the series system reduces the complexity of the water flow path, lowers production costs, and makes maintenance and troubleshooting easier.

[0074] Please see Figure 6 In another configuration, the water inlet pipe 20 includes a three-way component 21, a first branch 22, and a second branch 23. The three-way component 21 includes an inlet end, a first outlet end, and a second outlet end. The inlet end is connected to an inlet valve. The first branch 22 connects the first outlet end of the three-way component 21 to the drum assembly 10. The electrolytic cleaning device 30 is connected to the first branch 22. The second branch 23 connects the second outlet end of the three-way component 21 to the drum assembly 10. The slow-release cleaning device 40 is connected to the second branch 23. It should be noted that both the first branch 22 and the second branch 23 can independently supply water to the drum assembly 10. Therefore, users can flexibly select either the electrolytic cleaning device 30 or the slow-release cleaning device 40, or use both simultaneously, as needed. This allows users to customize washing programs for different types of clothing; for example, for clothing requiring deep cleaning, they can select simultaneous water intake from the first branch 22 and the second branch 23.

[0075] For loads that do not require additional detergent, users can simply select the first branch 22 equipped with the electrolytic cleaning device 30. Since using the slow-release cleaning device 40 produces more chemical detergent, which can damage certain fabrics, especially sensitive materials or brightly colored clothing, reducing detergent use mitigates this risk. The washing process is gentler on clothing fibers, helping to protect the fabric's texture and extend its lifespan. It also reduces chemical residue on clothing, which can cause skin irritation or allergies; using electrolyzed water reduces this risk. Furthermore, not using the slow-release cleaning device 40 reduces chemical detergent use, contributing to less environmental pollution, as chemical detergents released into the environment can negatively impact ecosystems.

[0076] Since the electrolytic cleaning device 30 requires electrical energy to generate electrolyzed water, the cleaning effect provided by the electrolytic cleaning device 30 may not be necessary when the stains on the clothes are light. In this case, the solid detergent provided by the slow-release cleaning device 40 is sufficient to achieve the cleaning effect. The user can simply use the second branch 23, which is equipped with the slow-release cleaning device 40, to introduce water into the drum assembly 10, thereby reducing the power consumption of the washing machine 100.

[0077] When the stains on the clothes to be treated are heavy, such as stubborn stains or grease, the electrolytic cleaning device 30 can provide strong cleaning power, while the slow-release cleaning device 40 can continuously release detergent, working together to remove stains more effectively. Furthermore, water is introduced into the drum assembly 10 through both the first branch 22 and the second branch 23, which can accelerate the water filling speed of the drum assembly 10 and improve the washing efficiency of the washing machine 100.

[0078] In another configuration, the water inlet pipe 20 includes a four-way component and a third branch. The four-way component includes an inlet end, a first outlet end, a second outlet end, and a third outlet end. The inlet end is connected to the water inlet valve. The first branch 22 connects the first outlet end of the four-way component and the drum assembly 10. The electrolytic cleaning device 30 is connected to the first branch 22. The second branch 23 connects the second outlet end of the four-way component and the drum assembly 10. The slow-release cleaning device 40 is connected to the second branch 23. The third branch connects the third outlet end of the four-way component and the drum assembly 10. The washing machine 100 also includes a blue oxygen cleaning device, a color-protecting sterilization device, and an anion sterilization device. At least one of the blue oxygen cleaning device, the color-protecting sterilization device, and the anion sterilization device is connected to the third branch. The effects of the first branch 22 and the second branch 23 can be referred to the above and will not be repeated here. The blue oxygen cleaning device includes a blue oxygen generator and other related equipment for generating blue oxygen (a strong oxidant) to oxidize and decompose organic matter and pollutants in the water. The Color Care and Refreshment (CCR) device contains polymer materials primarily used to protect the color of clothing while also providing sterilization. It incorporates multiple functions including filtration, adsorption, and sterilization, aiming to remove impurities and bacteria from the water to prevent fading or bacterial damage to clothing during washing. Anion sterilization devices, such as electro-deionization (EDI) modules, are mainly used to remove cations and anions from the water to improve water purity. EDI modules selectively remove ions from the water through ion exchange and electric field forces, achieving deep purification and desalination. Therefore, the third branch provides additional cleaning and sterilization methods, which can be combined with the functions of the first branch 22 and the second branch 23 to achieve multiple cleaning and sterilization effects.

[0079] In some embodiments, the washing machine 100 includes a cabinet (not shown), and the water inlet pipe 20 includes a detergent dispenser 24. The detergent dispenser 24 is installed inside the cabinet and has a storage cavity and an opening communicating with the outside. The opening is covered with a lid. The detergent dispenser 24 is installed in a position accessible to the user, such as the top of the cabinet. The user can expose the storage cavity of the detergent dispenser 24 by pulling open the lid or by flipping open the lid. This application does not limit this. The user can observe whether the slow-release cleaning device 40 inside the detergent dispenser 24 needs to be replaced. Further, the detergent dispenser 24 is connected to the drum assembly 10. The slow-release cleaning device 40 is replaceably provided inside the detergent dispenser 24, that is, the user can purchase and replace the slow-release element 43 in the slow-release cleaning device 40 separately. The slow-release element 43 is a small dose. Regularly replacing the slow-release cleaning device 40 helps maintain the hygiene of the washing machine 100, reducing the accumulation of bacteria and mold. The easily accessible location of the detergent dispenser 24 and the replaceability of the slow-release cleaning device 40 provide users with a convenient and economical laundry solution.

[0080] Please see Figure 4 When the slow-release cleaning device 40 is a user-replaceable slow-release cleaning device 40, the replaceable slow-release cleaning device 40 includes a housing 41, a container 42, and a slow-release element 43 installed in the container 42. The shape of the housing 41 can be adapted to the storage cavity of the detergent box 24. The housing 41 is the external structure of the slow-release cleaning device 40, providing physical protection and structural support. The housing 41 has at least one set of relatively arranged flow holes 41a. The flow holes 41a are arranged facing the water flow direction and communicate with the storage cavity. When the water flow is from front to back, the flow holes 41a are arranged in the front-back direction of the housing 41. When the water flow is from top to bottom, the flow holes 41a are arranged in the up-down direction of the housing 41. Understandably, the housing 41 may also be provided with two sets of flow holes 41a or three sets of flow holes 41a. This application does not limit this. The container 42 is used to contain the slow-release body 43. It has a container cavity 42a and several perforated holes 42b communicating with the container cavity 42a. The slow-release body 43 is contained in the container cavity 42a. When water flows through the flow hole 41a in the flow direction, it fully contacts the slow-release body 43 through the several perforated holes 42b of the container 42, promoting the uniform dissolution of the slow-release body 43.

[0081] Please continue reading. Figure 4It should be noted that the cross-sectional area of ​​the flow hole 41a is larger than that of the perforated hole 42b. The larger cross-sectional area of ​​the flow hole 41a can ensure that the resistance of the water flow is small when passing through the shell 41, thereby increasing the water flow rate and ensuring that enough water flows into the shell 41 to dissolve the slow-release body 43. The smaller diameter of the perforated hole 42b can prevent the slow-release body 43 in the receiving cavity 42a from flowing out of the receiving body 42 with the direction of water flow, ensuring that the slow-release body 43 is fully utilized in the receiving body 42, extending its service life and achieving long-term use effect.

[0082] Specifically, the housing 41 includes an upper shell and a lower shell. The upper shell has external threads, and the lower shell has internal threads. The user can expose the accommodating body 42 by screwing it on. The inner wall of the housing 41 is also provided with limiting ribs. The limiting ribs can restrict the position of the accommodating body 42, so that the accommodating body 42 is spaced apart from the inner wall of the housing 41, so that water entering the housing 41 can fully contact the accommodating body 42.

[0083] In some embodiments, the slow-release agent 43 can also be configured to a larger dose, and the slow-release cleaning device 40 can be placed in a location out of user reach, thereby reducing the risk of accidental operation or child contact and improving safety. In one configuration, the slow-release cleaning device 40 is mounted on the outer wall of the drum assembly 10, close to the drum assembly 10, allowing for more direct slow release of detergent into the washing water and improving cleaning efficiency. In another configuration, the slow-release cleaning device 40 is mounted on the inner wall of the casing, ensuring it is not disturbed during daily use and is less prone to accidental damage. The casing provides a certain degree of physical protection for the slow-release cleaning device 40, reducing the risk of damage due to external forces. In yet another configuration, the washing machine 100 also includes a base and a support frame 50 mounted on the base. The drum assembly 10 is installed within the support frame 50 and supported on the base, while the slow-release cleaning device 40 is mounted on the support frame 50. The support frame 50 provides stable support, especially for the larger dose of the slow-release agent 43, which is also heavier, ensuring the stability of the slow-release cleaning device 40 during use.

[0084] Please see Figure 7 , Figure 8 and Figure 9When the slow-release cleaning device 40 is a long-term slow-release cleaning device 40, the long-term slow-release cleaning device 40 includes a housing 41, a container 42, and a slow-release body 43. The support frame 50 includes an upper crossbeam 51, which is located at the front end near the dispensing port of the washing machine 100. The housing 41 can be installed on the upper crossbeam 51 and is located below the upper crossbeam 51. One side surface of the housing 41 is attached to and fixedly connected to the lower surface of the upper crossbeam 51. One side of the housing 41 extends outward to form a connecting lug. A first connecting hole is provided on the connecting lug, and a corresponding second connecting hole is provided on the upper crossbeam 51. One of the first connecting hole and the second connecting hole is a smooth hole, and the other is a threaded hole. After the screw passes through the smooth hole, it is fastened to the threaded hole to achieve a fixed connection between the housing 41 and the upper crossbeam 51. Alternatively, both the first connecting hole and the second connecting hole are smooth holes. The bolt passes through the first connecting hole and the second connecting hole and is engaged with the nut to achieve a fixed connection between the housing 41 and the upper crossbeam 51.

[0085] The housing 41 has an immersion chamber 41b inside, and the container 42 is confined within the housing 41. The water flow from the inlet pipe 20 can flow into the immersion chamber 41b to immerse the container 42. To ensure that the container 42 is confined within the immersion chamber 41b, multiple fixing ribs are provided on the cavity wall of the immersion chamber 41b. The fixing ribs provide positioning for the container 42 around its perimeter to prevent it from shaking within the housing 41. On the other hand, they can create a gap between the outer wall of the housing 41 and the inner wall of the container 42. This gap forms a water channel when water enters, and the container 42 is immersed in the immersion chamber 41b. The container 42 has a immersion cavity 42a for accommodating the slow-release body 43, and several perforated holes 42b communicating with the immersion cavity 42a. The slow-release body 43 is used to dissolve in the water in the inlet pipe 20 to generate a slow-release cleaning substance and supply it to the tubular assembly 10.

[0086] It should be noted that the housing 41 also has an inlet 41c and an outlet 41d that are connected to the immersion chamber 41b. The inlet 41c is connected to the water inlet pipe 20, and the outlet 41d is connected to the drum assembly 10. Along the vertical direction of the washing machine 100, the outlet 41d is lower than the inlet 41c. The inlet 41c can be opened in the upper part of the housing 41 so that the water flowing into the inlet 41c can fully contact the slow-release body 43 in the container 42. Gravity promotes the water flow through the immersion chamber 41b, the slow-release body 43 is dissolved, and then the cleaning agent is delivered to the drum assembly 10 through the outlet 41d.

[0087] Furthermore, the lower part of the shell 41 is provided with a notch, which allows the slow-release liquid in the immersion chamber 41b to converge towards the side with the outlet 41d, improving the efficiency of the slow-release liquid flow, avoiding the retention of the slow-release liquid in the lower part of the shell 41, reducing the bacterial growth or odor that may be caused by the retention of the slow-release liquid in the slow-release body 43, helping the slow-release liquid to be discharged from the immersion chamber 41b more quickly, and also reducing the unnecessary long-term immersion of the slow-release body 43 in water.

[0088] Please see Figure 9 In some embodiments, the drum assembly 10 has a first water inlet 10b for connecting the slow-release cleaning device 40. In the height direction of the washing machine 100, the slow-release cleaning device 40 is higher than the first water inlet 10b, which helps to prevent the slow-release agent 43 from excessively dissolving due to prolonged soaking in water, reducing unnecessary waste and thus saving washing costs. Reducing the prolonged soaking of the slow-release agent 43 in water can extend the service life of the detergent, ensuring that an appropriate amount of detergent is released evenly each time, thereby reducing waste. Furthermore, reducing unnecessary dissolution of the slow-release agent 43 means that the frequency of detergent maintenance and replacement can be reduced, decreasing the workload for the user in maintaining the slow-release cleaning device 40.

[0089] Specifically, the slow-release cleaning device 40 is higher than the drum assembly 10. If the slow-release cleaning device 40 is lower than the water level line, water may backflow, causing water accumulation inside the slow-release cleaning device 40 and unnecessary dissolution of the slow-release agent 43. Therefore, setting the slow-release cleaning device 40 higher than the drum assembly 10 can effectively prevent water in the washing machine 100 from flowing back into the slow-release cleaning device 40 when it is not in operation. Furthermore, due to gravity, water flowing through the slow-release cleaning device 40 is more likely to flow from a higher position to the lower position inside the drum assembly 10, reducing the time that water remains in the slow-release cleaning device 40.

[0090] Please continue reading. Figure 9 In some embodiments, the drum assembly 10 includes a drum body 11 and a door seal 12 connected to the front side of the drum body 11. The drum body 11 has the aforementioned washing chamber 10a, and the door seal 12 is used to seal the gap between the door of the washing machine 100 and the drum body 11 to prevent water leakage and ensure the airtightness of the washing process. The door seal 12 is usually made of a soft and elastic material, such as rubber or silicone, which ensures that it can fit tightly against the door frame and the drum body 11 when the door is closed, thereby achieving a good sealing effect. The slow-release cleaning device 40 is connected to the door seal 12 through a pipe, which communicates with the washing chamber 10a of the drum body 11. Understandably, the slow-release cleaning device 40 is mounted on the upper crossbeam 51 of the support frame 50 and is located on the side close to the door seal 12. The pipe is connected from top to bottom to the slow-release cleaning device 40 and the door seal 12, so that water in the water inlet pipe 20 soaks through the slow-release cleaning device 40 and then flows into the washing chamber 10a through the pipe.
