Description

Technical Field

[0001] This disclosure relates to the field of household appliance technology, and in particular to a washing machine. Background Technology

[0002] Washing machines are clothing processing devices that convert electrical energy into mechanical energy to wash clothes. They are now commonplace in almost every household.

[0003] Currently, many washing machines are equipped with door seals. These seals connect the water inlet to the drum opening, preventing water from flowing into the machine's interior. During washing, the door seal and the adjacent door surface come into contact with the water, making them prone to accumulating dirt and other debris. After washing, the door seal and door remain in a damp, dark environment for an extended period, making them highly susceptible to the growth of bacteria, mold, and other harmful microorganisms on their surface and the inside of the door. This often results in unpleasant odors, severely impacting the user experience and health. Utility Model Content

[0004] In view of this, the purpose of this disclosure is to provide a washing machine that improves the technical problem of foreign matter, bacteria, mold and other harmful microorganisms existing on the surface of the door seal and the inner side of the door in the prior art.

[0005] To achieve at least one of the above objectives, this disclosure provides the following technical solutions:

[0006] In a first aspect, a washing machine is provided, comprising:

[0007] The container is equipped with a dispensing port;

[0008] The cylinder assembly is located inside the housing and has a cylinder opening that is directly opposite the dispensing port.

[0009] A door seal ring is installed between the inlet and the cylinder opening, and the door seal ring is configured to seal the gap between the inlet and the cylinder opening;

[0010] The cleaning structure includes a nozzle mechanism, a water inlet control unit, and piping connecting the nozzle mechanism and the water inlet control unit;

[0011] The nozzle mechanism includes:

[0012] The water inlet pipe passes through the door seal ring;

[0013] The outer shell is located inside the door seal ring. The interior of the outer shell forms an installation cavity and is connected to the pipeline through a water inlet pipe. The outer shell wall is provided with a first spray port that is connected to the installation cavity and faces the surface of the door seal ring.

[0014] The material box is detachably installed in the installation cavity. The inside of the material box forms a cavity for holding the bactericidal and mildew-removing agent. The box wall is provided with water-permeable holes.

[0015] The water inlet control unit is configured to control the water flow into the housing through the pipeline and the water inlet pipe, and to spray it out from the first spray port;

[0016] In this process, at least a portion of the water flows into the receiving cavity through the water permeable hole, causing at least a portion of the bactericidal and mold-removing components on the bactericidal and mold-removing agent to dissolve in the water flow. The water flow containing the bactericidal and mold-removing components can flow out of the receiving cavity through the water permeable hole and be sprayed onto the surface of the door seal ring through the first spray nozzle.

[0017] The above technical solution includes an added cleaning structure. In this structure, the nozzle mechanism is connected to the water inlet control unit via a pipeline. The water inlet control unit controls the water flow to enter the nozzle mechanism through the pipeline and sprays the water from the first spray nozzle towards the surface of the door seal ring. This cleans the door seal ring and removes any foreign matter adhering to it. Furthermore, the nozzle mechanism also includes a container for a built-in bactericide and mold remover. The water flow used to clean the door seal ring passes through the container and the bactericide and mold remover inside. When the water flows over the surface of the bactericide and mold remover, the bactericide and mold remover components dissolve in the water and are sprayed onto the surface of the door seal ring through the first spray nozzle. This simultaneously cleans the door seal ring and kills bacteria, mold, and other harmful microorganisms adhering to it, preventing mold growth and odors, improving the user experience, and reducing the impact on user health. In addition, since the outer casing is located inside the door seal ring, and the detergent dispenser is detachably installed in the mounting cavity of the outer casing, the detergent dispenser can be exposed inside the door seal ring. When it is necessary to replace the detergent dispenser, it can be accessed after opening the door, which facilitates the replacement of the detergent dispenser. This allows the antibacterial and anti-mold agent in the detergent dispenser to continuously and stably provide sufficient antibacterial and anti-mold ingredients and release them slowly into the water flow. This ensures that the door seal ring and the washing machine maintain a good antibacterial and anti-mold effect throughout the entire life cycle of the washing machine, better meeting the long-term health needs of users.

[0018] In some embodiments, the outer shell wall is further provided with an inlet and outlet, which are connected to the mounting cavity;

[0019] The material box can be pulled out and installed in the mounting cavity through the inlet and outlet;

[0020] When the material box is installed in the mounting cavity, the inlet and outlet are blocked by the material box.

[0021] In the above technical solution, by setting inlet and outlet on the shell wall, the material box can be pushed into the mounting cavity through the inlet and outlet, and can also be pulled out from the mounting cavity through the inlet and outlet. That is, the assembly between the material box and the shell is similar to a drawer-type structure, allowing the material box to be pulled out and assembled into the mounting cavity of the shell. This structural design makes it easy to pull out the material box from the shell and put the material box into the shell, which is beneficial for the replacement of the material box. Moreover, after the material box is assembled into the mounting cavity, the inlet and outlet can be blocked by the material box, so that the water flow will not flow out from the inlet and outlet, but will be guided to spray out from the first spray nozzle to directionally rinse the surface of the door seal ring.

[0022] In some embodiments, a locking mechanism is provided between the material box and the outer casing;

[0023] The locking mechanism is configured to lock the cassette to the housing after it is assembled in the mounting cavity, and to release the cassette from the housing so that it can be pulled out of the mounting cavity.

[0024] In the above technical solution, after the material box is assembled into the mounting cavity of the outer shell, the locking mechanism can be used to lock and fix the material box to the outer shell, thereby improving the stability of the material box after assembly and minimizing the risk of the material box detaching from the outer shell due to the impact of water flow; the locking mechanism can also be used to unlock the material box from the outer shell, making it convenient to remove the material box from the outer shell.

[0025] In some embodiments, the cartridge includes:

[0026] The loading and unloading port is located on the wall of the material box and is connected to the receiving cavity;

[0027] The lid is configured to open or close the opening.

[0028] In the above technical solution, the material box adopts an openable and closable structural design, that is, the material box is provided with a pick-up and put-out port and a box cover that matches the pick-up and put-out port. By opening the box cover, the bactericide and mold remover can be put into or taken out of the receiving cavity through the pick-up and put-out port. By closing the box cover, the bactericide and mold remover can be confined within the receiving cavity of the material box. This structural design facilitates the replacement of the bactericide and mold remover in the material box. Moreover, when the bactericide and mold remover is ineffective or has a low effective ingredient content, it is not necessary to replace the entire material box. Only the bactericide and mold remover in the receiving cavity needs to be replaced, which can save costs.

[0029] In some embodiments, the permeable hole includes a first permeable hole and a second permeable hole;

[0030] The first water-permeable hole is configured to connect the inner cavity of the receiving cavity and the water inlet pipe, and to confine the bactericidal and antifungal agent within the receiving cavity.

[0031] The second permeable hole is configured to connect the receiving cavity and the first spray port, thereby confining the bactericidal and antifungal agent within the receiving cavity.

[0032] In the above technical solution, by setting the first water permeable hole, the water flow in the water inlet pipe can be easily introduced into the receiving cavity of the material box and come into contact with the built-in bactericidal and mildew-removing agent to release bactericidal and mildew-removing components in the water flow; by setting the second water permeable hole, the water flow containing the bactericidal and mildew-removing components can be easily introduced from the receiving cavity of the material box to the first spray nozzle to spray onto the surface of the door seal ring.

[0033] In some embodiments, a first cavity is further formed inside the housing, the first cavity is connected to the mounting cavity, and the first cavity is disposed between the water inlet pipe and the material box;

[0034] The material box has a first water-permeable hole on the box wall facing the first cavity.

[0035] In the above technical solution, the first cavity is formed inside the outer shell and can be used as a buffer space between the water inlet pipe and the material box. The first cavity can temporarily store the water flowing into the outer shell from the water inlet pipe, and try to avoid the water flowing directly into the receiving cavity of the material box through the first water permeable hole, so as to avoid causing a large impact on the bactericidal and mildew-removing agent in the receiving cavity, and breaking or rapidly consuming the bactericidal and mildew-removing components on the surface of the bactericidal and mildew-removing agent, so that the bactericidal and mildew-removing components cannot be slowly released into the water flow and thus wasted. Moreover, in combination with the first water permeable hole opened on the material box, the first water permeable hole can be arranged in multiple ways. The water temporarily stored in the first cavity can enter the receiving cavity through multiple first water permeable holes. That is, the water can enter the receiving cavity from different positions and can mix evenly and fully with the bactericidal and mildew-removing agent in the receiving cavity, which is conducive to better slow release of the bactericidal and mildew-removing components on the bactericidal and mildew-removing agent into the water flow. In addition, the first water-permeable hole is located on the box wall facing the first cavity of the material box, which can shorten the path of water flow from the first cavity into the receiving cavity of the material box, and can guide most of the water flow into the receiving cavity to come into contact with the bactericidal and mildew-removing agent, so that the water flow can dissolve more bactericidal and mildew-removing components, which is beneficial to improving the bactericidal and mildew-removing effect on the door seal ring.

[0036] In some embodiments, a second cavity is further formed inside the housing, the second cavity being connected to the mounting cavity, and the second cavity being disposed between the first injection port and the material box;

[0037] A second water-permeable hole is provided on the wall of the material box facing the second cavity.

[0038] In the above technical solution, the second cavity is formed inside the outer shell and located between the material box and the first spray nozzle. The second cavity can temporarily store the water flowing from the material box into the outer shell. The water in the material box contains dissolved bactericidal and antifungal ingredients. When the water containing the bactericidal and antifungal ingredients enters the second cavity through the second water permeable hole, it can be further mixed so that the bactericidal and antifungal ingredients can be more evenly and fully dissolved in the water before being sprayed out from the first spray nozzle. Moreover, the second water permeable hole is located on the box wall of the material box facing the second cavity, which can shorten the path of the water flowing from the material box's receiving cavity into the second cavity, so that the water in the receiving cavity can be directed and quickly guided into the second cavity.

[0039] In some embodiments, a first cavity is further formed inside the housing, the first cavity is connected to the mounting cavity, and the first cavity is disposed between the water inlet pipe and the material box;

[0040] A first water-permeable hole is provided on the box wall facing the first cavity;

[0041] The outer shell also has a second cavity, which is connected to the mounting cavity and is located between the first injection port and the material box.

[0042] A second water-permeable hole is provided on the box wall facing the second cavity;

[0043] A flow channel is provided between the first cavity and the second cavity to allow water to flow through.

[0044] In the above technical solution, a first cavity and a second cavity are provided inside the outer shell. Water in the first cavity can enter the receiving cavity of the material box through the first water permeable hole and mix with the bactericidal and mildew-removing agent, so that the bactericidal and mildew-removing components on the bactericidal and mildew-removing agent dissolve in the water. The water containing the bactericidal and mildew-removing components can enter the second cavity through the second water permeable hole and can be sprayed out from the first spray nozzle. Based on this, by setting a flow channel between the first cavity and the second cavity, the first cavity and the second cavity can be directly connected. This allows part of the water flow entering the first cavity through the water inlet pipe to enter the second cavity directly without passing through the inside of the material box and be sprayed out from the first spray nozzle. The flow path of this part of the water flow in the nozzle mechanism is reduced, which can enhance the impact force of the water flow when it is sprayed out from the first spray nozzle, which is beneficial for removing foreign objects adhering to the door seal ring. Moreover, the water flow that enters the second cavity directly from the first cavity can also impact the water flow entering the second cavity from the material box (which contains antibacterial and antifungal ingredients), so that the two water flows can be fully mixed. This allows the antibacterial and antifungal ingredients to be more evenly and fully dissolved in the water flow in the second cavity before being sprayed out from the first spray nozzle.

[0045] In some embodiments, the dispensing port is located on the front face of the box, the cylinder opening is arranged directly opposite the dispensing port along the front-back direction of the box, and the door seal ring is connected between the dispensing port and the cylinder opening;

[0046] The outer casing is located on the top inner side of the door seal ring;

[0047] The outer casing has multiple first injection ports, which are distributed on both sides of the outer casing along the left-right direction of the housing.

[0048] In the above technical solution, by setting the outer shell of the nozzle mechanism on the top inner side of the door seal ring and distributing multiple first spray nozzles along the left and right directions of the housing on both sides of the outer shell, the water flow can first spray onto the top of the surface of the door seal ring after passing through the first spray nozzles, and then flow from top to bottom along both sides of the surface to comprehensively spray and rinse the surface of the door seal ring, thereby improving the cleaning effect.

[0049] In some embodiments, the dispensing port is located on the front face of the box, the cylinder opening is arranged directly opposite the dispensing port along the front-back direction of the box, and the door seal ring is connected between the dispensing port and the cylinder opening;

[0050] The outer casing is located on the top inner side of the door seal ring;

[0051] The housing has at least one first injection port, and the at least one first injection port is located on one side of the housing along the left-right direction of the box.

[0052] In the above technical solution, the first spray nozzle is set on one side of the outer shell along the left and right direction of the housing, that is, in the left and right direction of the housing, all the first spray nozzles on the outer shell are located on the same side of the outer shell. Compared with the structure in which the first spray nozzles are distributed on different sides of the outer shell, setting the first spray nozzle only on one side of the outer shell can make the impact force of the water flow sprayed through the first spray nozzle stronger, and can make the water flow more concentrated to directionally rinse part of the surface of the door seal ring, thereby improving cleaning efficiency and effect.

[0053] In some embodiments, a door is provided at the dispensing port of the container, and the door is configured to open or close the dispensing port;

[0054] The outer shell wall is also provided with a second spray nozzle, which is connected to the mounting cavity and faces the inner surface of the door body;

[0055] The water-permeable hole includes a third water-permeable hole, which is configured to connect the receiving cavity and the second spray port, and to confine the bactericidal and antifungal agent within the receiving cavity;

[0056] Under the control of the water inlet control unit, the water flowing out of the receiving cavity through the third water permeable hole is sprayed out through the second spray nozzle and sprayed onto the inner surface of the door.

[0057] In the above technical solution, by setting a second spray nozzle on the outer shell, the water inlet control unit can control the water flow to enter the nozzle mechanism through the pipeline, and spray the water from the second spray nozzle toward the inner surface of the door, which can rinse and clean the inner surface of the door and remove foreign matter adhering to the inner surface of the door. Moreover, the nozzle mechanism is also equipped with a material box containing a built-in bactericidal and mold-removing agent, and a third water-permeable hole connects the receiving cavity and the second spray nozzle. The water flow used to clean the inner surface of the door can flow through the receiving cavity of the material box and the bactericidal and mold-removing agent in the cavity. When the water flow passes over the surface of the bactericidal and mold-removing agent, the bactericidal and mold-removing components on the bactericidal and mold-removing agent can dissolve in the water flow and be sprayed onto the inner surface of the door through the second spray nozzle along with the water flow. This can kill bacteria, mold and other harmful microorganisms adhering to the inner surface of the door while cleaning the inner surface of the door, so as to prevent the inner surface of the door from becoming moldy and producing odors, improve the user's product experience, and reduce the impact on the user's health.

[0058] In some embodiments, a third cavity is further formed inside the housing, the third cavity being connected to the mounting cavity, and the third cavity being disposed between the second injection port and the material box;

[0059] A third water-permeable hole is provided on the wall of the material box facing the third cavity.

[0060] In the above technical solution, the third cavity is formed inside the outer shell and is located between the material box and the second spray nozzle. The third cavity can temporarily store the water flow entering the outer shell from the material box. The water flow in the material box contains bactericidal and anti-mold ingredients. When the water flow containing bactericidal and anti-mold ingredients enters the third cavity through the third water permeable hole, it can be further mixed so that the bactericidal and anti-mold ingredients can be more evenly and fully dissolved in the water flow before being sprayed out from the second spray nozzle.

[0061] In some embodiments, the bactericide and fungicide is a skeleton-type formulation capable of slowly releasing bactericide and fungicide components in water, including:

[0062] The drug-loaded matrix is ​​granular and insoluble in water.

[0063] The antibacterial and antifungal ingredients are loaded onto a drug-carrying matrix.

[0064] In the above technical solution, since the bactericide and fungicide is a skeleton-type formulation that can slowly release bactericide and fungicide components in water, the use of this bactericide and fungicide can provide bactericide and fungicide components to the water flow for a long time and continuously, thereby improving the bactericide and fungicide effect and reducing the replacement frequency of the bactericide and fungicide. Moreover, the drug carrier skeleton in the bactericide and fungicide is granular and insoluble in water. By designing the drug carrier skeleton to an appropriate size, the drug carrier skeleton can always be confined within the receiving cavity of the material box, so as to prevent the bactericide and fungicide or the drug carrier skeleton from entering the pipeline or the space between the nozzle mechanism and the material box and causing blockage, or prevent the bactericide and fungicide or the drug carrier skeleton from entering the door seal ring or cylinder assembly and causing waste and pollution of the agent.

[0065] Secondly, a washing machine is also provided, comprising:

[0066] The container is equipped with a dispensing port and a door for opening or closing the dispensing port;

[0067] The cylinder assembly is located inside the housing and has a cylinder opening that is directly opposite the dispensing port.

[0068] A door seal ring is installed between the inlet and the cylinder opening, and the door seal ring is configured to seal the gap between the inlet and the cylinder opening;

[0069] The cleaning structure includes a nozzle mechanism, a water inlet control unit, and piping connecting the nozzle mechanism and the water inlet control unit;

[0070] The nozzle mechanism includes:

[0071] The water inlet pipe passes through the door seal ring;

[0072] The outer shell is located inside the door seal ring. The interior of the outer shell forms an installation cavity and is connected to the pipeline through a water inlet pipe. The outer shell wall is provided with a second spray nozzle that is connected to the installation cavity and faces the inner surface of the door.

[0073] The material box is detachably installed in the installation cavity. The inside of the material box forms a cavity for holding the bactericidal and mildew-removing agent. A third water permeable hole is provided on the box wall. The third water permeable hole is configured to connect the cavity and the second spray nozzle, and to confine the bactericidal and mildew-removing agent within the cavity.

[0074] The water inlet control unit is configured to control the water flow into the housing through the pipeline and the water inlet pipe, and to spray it out from the second spray port;

[0075] At least a portion of the water flows into the receiving cavity, causing at least a portion of the bactericidal and mold-removing components on the bactericidal and mold-removing agent to dissolve in the water. The water containing the bactericidal and mold-removing components can flow out of the receiving cavity through the third water-permeable hole and be sprayed onto the inner surface of the door through the second spray nozzle.

[0076] The above technical solution includes an added cleaning structure. Within this structure, the nozzle mechanism is connected to a water inlet control unit via a pipeline. The water inlet control unit controls the water flow through the pipeline into the nozzle mechanism, and the water is sprayed from the second spray nozzle toward the inner surface of the door. This cleans the inner surface of the door, removing any foreign matter adhering to it. Furthermore, the nozzle mechanism also contains a container for a built-in bactericide and mold remover. The water used to clean the inner surface of the door flows through the container and the bactericide and mold remover inside. When the water flows over the surface of the bactericide and mold remover, the bactericide and mold remover components dissolve in the water and are sprayed onto the inner surface of the door along with the water flow through the second spray nozzle. This cleans the inner surface of the door while simultaneously killing bacteria, mold, and other harmful microorganisms, preventing mold growth and odors, improving the user experience, and reducing the impact on user health. In addition, since the outer casing is located inside the door seal ring, and the detergent dispenser is detachably installed in the mounting cavity of the outer casing, the detergent dispenser can be exposed inside the door seal ring. When the detergent dispenser needs to be replaced, it can be accessed after opening the door, which facilitates the replacement of the detergent dispenser. This allows the antibacterial and anti-mold agent in the detergent dispenser to continuously and stably provide sufficient antibacterial and anti-mold ingredients and release them slowly into the water flow. This ensures that the door and the washing machine maintain a good antibacterial and anti-mold effect throughout the entire life cycle of the washing machine, better meeting the long-term health needs of users.

[0108] As part of the inventive concept of this disclosure, before describing the embodiments of this disclosure, it is necessary to analyze the reasons for the problem of foreign objects, bacteria, mold and other harmful microorganisms existing on the surface of the door seal ring and the inner side of the door in the related art, and obtain the technical solution of the embodiments of this disclosure through reasonable analysis.

[0109] In related technologies, washing machines are clothing processing devices that convert electrical energy into mechanical energy to wash clothes. They are now widely used in households. Currently, many washing machines are equipped with a door seal ring, which connects the water inlet of the washing machine body to the opening of the washing drum, preventing water from the washing drum from flowing into the interior of the machine body. During washing, the door seal ring and the door body adjacent to it come into contact with the washing water, making it easy for dirt and other foreign objects to adhere. After washing, the door seal ring and the door body are in a dark and damp environment for a long time, making it very easy for bacteria, mold, and other harmful microorganisms to adhere to the surface of the door seal ring and the inner surface of the door body, often accompanied by unpleasant odors, seriously affecting the user experience and health.

[0110] To address this, the present disclosure provides a washing machine that, by adding a cleaning structure, can not only clean the surface of the door seal ring and the door body, but also provide antibacterial and anti-mold ingredients to the door seal ring and the door body during cleaning, thereby solving the technical problem in the prior art of foreign matter and harmful microorganisms such as bacteria and mold on the surface of the door seal ring and the inner side of the door body.

[0111] The technical solutions of the embodiments of this disclosure are described in detail below with reference to the accompanying drawings. The technical features involved in the different embodiments of this disclosure described below can be combined with each other as long as they do not conflict with each other.

[0112] The washing machine can be a front-loading washing machine or a washer-dryer combo, etc. For the convenience of describing the following embodiments, this disclosure takes a front-loading washing machine as an example to specifically describe the structure of the washing machine.

[0113] Please refer to the above. Figures 1 to 9 , Figure 1 and Figure 2 A schematic diagram of the external structure of a washing machine is provided, showing the basic components of the washing machine. Figure 3 A schematic diagram of the internal structure of a washing machine is provided, showing a structural relationship in which a cleaning structure is installed inside the washing machine. Figure 4 and Figure 5 A schematic diagram of a door seal ring is provided, showing a positional relationship between the nozzle mechanism and the door seal ring. Figures 6 to 9 A schematic diagram of the external and internal structure of a nozzle mechanism is provided, showing the structural relationship between the water inlet pipe, the outer shell, and the material box in the nozzle mechanism.

[0114] An embodiment of this disclosure provides a washing machine, such as Figures 1 to 3 As shown, the washing machine includes a cabinet 1, a drum assembly 2, a door seal ring 3, and a cleaning structure 4.

[0115] The box body 1 is provided with a dispensing port 11; the cylinder assembly 2 is located inside the box body 1, and the cylinder assembly 2 has a cylinder opening 21 arranged directly opposite to the dispensing port 11; the door seal ring 3 is located between the dispensing port 11 and the cylinder opening 21; the cleaning structure 4 can not only clean the surface of the door seal ring 3, but also provide bactericidal and mildew-removing ingredients to the door seal ring 3 at the same time to remove foreign matter adhering to the door seal ring 3 and kill bacteria, mold and other harmful microorganisms attached to the door seal ring 3.

[0116] In this embodiment, as Figure 1 and Figure 2 As shown, the housing 1 forms the outer shell 412 of the washing machine, which is usually a rectangular hollow structure. The appearance of the housing 1 can be designed as needed and is not limited here. The housing 1 has an inner cavity, which can provide installation space for components such as the drum assembly 2 and the door seal ring 3.

[0117] The cabinet 1 is provided with a dispensing port 11, which is roughly circular and located on the front end face of the cabinet 1. The dispensing port 11 connects to the inner cavity of the cabinet 1. Of course, the dispensing port 11 can also be located on other end faces of the cabinet 1, which is not limited here. However, for conventional drum washing machines, the dispensing port 11 is generally located on the front end face of the cabinet 1.

[0118] A door 12 is also installed on the housing 1. The door 12 is movably connected to the housing 1 near the dispensing port 11 via a shaft to open or close the dispensing port 11.

[0119] In this embodiment, as Figure 3 As shown, the drum assembly 2 is installed in the inner cavity of the box 1 and can be used for washing, rinsing, dehydrating and drying clothes.

[0120] The cylinder opening 21 on the cylinder assembly 2 is roughly circular and is located on the front end face of the cylinder assembly 2. The cylinder opening 21 is arranged directly opposite the delivery port 11 along the front-back direction of the box body 1.

[0121] The drum assembly 2 also has a washing chamber that can hold clothes; after the door 12 is opened, clothes can be put into or taken out of the washing chamber through the inlet 11 and the drum opening 21.

[0122] The drum assembly 2 includes an outer drum and an inner drum; the outer drum is disposed in the inner cavity of the housing 1, and the inner drum is rotatably disposed in the outer drum; the washing chamber is formed inside the inner drum, thereby enabling the inner drum to drive the clothes to rotate relative to the outer drum, improving the uniformity of washing and dehydrating the clothes; the outer drum and the inner drum can be arranged coaxially inside and outside, and the front end of the outer drum and the front end of the inner drum are provided with openings arranged opposite to each other, and the front end opening of the outer drum can be used as the drum opening 21 of the drum assembly 2.

[0123] In this embodiment, as Figure 4 and Figure 5As shown, the door seal ring 3 is roughly circular in shape and is connected between the inlet 11 and the cylinder opening 21. The door seal ring 3 is configured to seal the gap between the inlet 11 and the cylinder opening 21 to prevent water in the washing chamber from flowing into the inner cavity of the tank 1.

[0124] After the door 12 closes the inlet 11, the door seal ring 3 can also work together with the door 12 to seal the gap between the door 12 and the inlet 11, so as to prevent water in the washing chamber from flowing out from the gap between the door 12 and the inlet 11.

[0125] In this embodiment, as Figure 3 As shown, the cleaning structure 4 includes a water inlet control unit 42, a nozzle mechanism 41, and a pipe 43 connecting the water inlet control unit 42 and the nozzle mechanism 41. The water inlet control unit 42 controls the water flow through the pipe 43 to the nozzle mechanism 41, and the water flows through the nozzle mechanism 41 to spray onto the door seal ring 3 to clean the surface of the door seal ring 3 and remove foreign matter adhering to the surface of the door seal ring 3.

[0126] Furthermore, the water inlet control unit 42 can be a water inlet valve or a combination of a water inlet valve and a soap box 5.

[0127] When the water inlet control unit 42 is only a water inlet valve, the pipe 43 is directly connected to the outlet of the water inlet valve, and the water inlet valve can control the water flow introduced by the water inlet valve into the pipe 43. It should be understood that the water inlet valve can also supply water to the soap dish 5 through another outlet of the water inlet valve, so that the water inlet valve has more functions and can save the layout space of the washing machine.

[0128] When the water inlet control unit 42 is a combination structure of water inlet valve and soap box 5, the pipe 43 is connected to the soap box 5. The soap box 5 is provided with a flow channel connecting the pipe 43 and the water inlet valve. The water introduced by the water inlet valve can be controlled to flow through the flow channel in the soap box 5 into the pipe 43.

[0129] Of course, the specific configuration of the water inlet control unit 42 is not limited to the two structural methods mentioned above. It can be designed in accordance with the internal structural layout of the washing machine so that the water inlet control unit 42 can meet the water supply needs of the pipe 43 and the nozzle mechanism 41.

[0130] Furthermore, such as Figure 6 As shown, the nozzle mechanism 41 includes a water inlet pipe 411, a housing 412, and a material box 413.

[0131] The water inlet pipe 411 connects the pipe 43 and the outer casing 412. The outer casing 412 has a first spray nozzle 4121 facing the surface of the door seal ring 3. The material box 413 contains a bactericide and mold remover 4137 and is installed inside the outer casing 412. After the water flows into the outer casing 412 through the water inlet pipe 411, at least part of the water flows into contact with the bactericide and mold remover 4137. The bactericide and mold remover components on the bactericide and mold remover 4137 dissolve in the water. The water containing the bactericide and mold remover components can be sprayed onto the surface of the door seal ring 3 through the first spray nozzle 4121 to rinse the surface of the door seal ring 3 and perform bactericide and mold removal.

[0132] Specific description of the water inlet pipe 411: The water inlet pipe 411 passes through the door seal ring 3. Specifically, the door seal ring 3 has mounting holes that penetrate the inner and outer sides of its annular structure. The water inlet pipe 411 passes through the mounting holes of the door seal ring 3 and is fixed to the door seal ring 3.

[0133] One end of the water inlet pipe 411 passes through the mounting hole to the outside of the door seal ring 3 and is connected to the pipe 43. The water inlet pipe 411 and the pipe 43 can be connected and fixed by means of plug-in connection, threaded connection or other methods. The other end of the water inlet pipe 411 is located inside the door seal ring 3 and is connected to the outer shell 412. The water inlet pipe 411 and the outer shell 412 can be connected and fixed by means of plug-in connection, threaded connection or integral manufacturing or other methods.

[0134] Optionally, the water inlet pipe 411 extends radially through the top of the door seal ring 3, such as... Figure 3 As shown.

[0135] Optionally, the surface of the housing 412 connected to the water inlet pipe 411 is adapted to the surface of the door seal ring 3; when the water inlet pipe 411 is inserted through the mounting hole, the surface of the housing 412 connected to the water inlet pipe 411 can abut against a portion of the surface of the door seal ring 3 so that the water inlet pipe 411 is positioned and assembled onto the door seal ring 3.

[0136] By adopting the above structural design, the water inlet pipe 411 and the door seal ring 3 can be quickly assembled by positioning and cooperating the surface of the outer shell 412 connected to the water inlet pipe 411 with the surface of the door seal ring 3, which can improve assembly efficiency. Moreover, the surface of the outer shell 412 connected to the water inlet pipe 411 abuts against a part of the surface of the door seal ring 3, which can improve the stability of the nozzle mechanism 41 after assembly with the door seal ring 3, thereby improving the stability of the nozzle mechanism 41 during operation.

[0137] It should be noted that, in order to ensure the stability of the connection between the water inlet pipe 411 and the door seal ring 3, after the water inlet pipe 411 is inserted into the door seal ring 3, locking components such as clamps can be used to lock and fix the water inlet pipe 411 and the door seal ring 3.

[0138] Specific details regarding casing 412: (See below) Figures 4 to 6 As shown, the outer shell 412 is located inside the door seal ring 3. The outer shell 412 is a shell structure with an internal mounting cavity. The mounting cavity is formed by multiple shell walls. The mounting cavity of the outer shell 412 is connected to the interior of the pipe 43 through the water inlet pipe 411. A first spray port 4121 connected to the mounting cavity is provided on the shell wall of the outer shell 412, and the first spray port 4121 faces the surface of the door seal ring 3.

[0139] With the above structural design, the outer shell 412 is connected to the water inlet control unit 42 through the water inlet pipe 411 and the pipeline 43. The water inlet control unit 42 can control the water flow to enter the outer shell 412 through the pipeline 43 and the water inlet pipe 411, and make the water flow spray out from the first spray port 4121 toward the surface of the door seal ring 3, which can rinse and clean the door seal ring 3 and remove foreign matter adhering to the door seal ring 3.

[0140] Specific instructions regarding material box 413: (See below) Figures 6 to 9 As shown, the material box 413 is assembled in the installation cavity and the material box 413 is detachably connected to the outer shell 412. The material box 413 is a box structure with an internal receiving cavity. The receiving cavity is composed of multiple box walls. The receiving cavity of the material box 413 contains a bactericidal and mildew-removing agent 4137. The box wall of the material box 413 is provided with water-permeable holes.

[0141] Under the control of the water inlet control unit 42, water flows into the housing 412 through the pipe 43 and the water inlet pipe 411. At least part of the water flows into the receiving cavity through the water permeable hole, so that at least part of the bactericidal and mold-removing components on the bactericidal and mold-removing agent 4137 dissolves in the water. The water containing the bactericidal and mold-removing components can flow out of the receiving cavity through the water permeable hole and be sprayed onto the surface of the door seal ring 3 through the first spray nozzle 4121.

[0142] With the above structural design, a material box 413 containing a built-in bactericidal and mildew-removing agent 4137 is provided in the nozzle mechanism 41. At least part of the water flow entering the nozzle mechanism 41 can flow over the surface of the bactericidal and mildew-removing agent 4137 in the material box 413, so that the bactericidal and mildew-removing components are dissolved in the water flow. Then the water flow is sprayed onto the surface of the door seal ring 3 through the first spray nozzle 4121. While cleaning the door seal ring 3, it can also kill bacteria, mold and other harmful microorganisms attached to the door seal ring 3, so as to prevent the door seal ring 3 from becoming moldy and producing odors, improve the user's product experience and reduce the impact on the user's health.

[0143] In addition, since the outer casing 412 is located inside the door seal ring 3, and the feed box 413 is detachably disposed in the mounting cavity of the outer casing 412, the feed box 413 can be exposed inside the door seal ring 3. When the feed box 413 needs to be replaced, it can be accessed after opening the door 12, which is conducive to the replacement of the feed box 413. This allows the bactericidal and mildew-preventing agent 4137 in the feed box 413 to continuously and stably provide sufficient bactericidal and mildew-preventing ingredients and release them slowly into the water flow. This ensures that the door seal ring 3 and the washing machine maintain a good bactericidal and mildew-preventing effect throughout the entire life cycle of the washing machine, better meeting the long-term health needs of users.

[0144] Optionally, the bactericide and fungicide 4137 is a matrix-type formulation capable of slowly releasing bactericide and fungicide components in water. Exemplarily, a specific structure of the bactericide and fungicide 4137 may be: the bactericide and fungicide 4137 includes a drug-loaded matrix and a bactericide and fungicide component, with the bactericide and fungicide component loaded on the drug-loaded matrix.

[0145] With the above structural design, since the bactericide and fungicide 4137 is a skeleton-type formulation that can slowly release bactericide and fungicide components in water, the use of this bactericide and fungicide 4137 can provide bactericide and fungicide components to the water flow for a long time and continuously, thereby improving the bactericide and fungicide effect and reducing the replacement frequency of the bactericide and fungicide 4137.

[0146] Optionally, the drug-carrying matrix can be granular and insoluble in water; thus, the bactericide and fungicide 4137 can also be granular.

[0147] It should be understood that after the bactericidal and mold-removing components on the bactericidal and mold-removing agent 4137 are completely and slowly released into the water, a drug skeleton will remain in the water.

[0148] Please refer to the above. Figure 6 , Figure 9 , Figure 10 , Figure 12 and Figure 13 , Figure 6 and Figure 9 A schematic diagram of the material box in the nozzle mechanism in both assembled and disassembled states is provided; the structural relationship between the outer shell and the material box is shown. Figure 10 A schematic diagram of the nozzle mechanism after removing the material box is provided; the internal structure of the outer shell is shown. Figure 12 and Figure 13 A schematic diagram of the external and internal structure of a material box is provided; it shows the internal and external structure of the material box.

[0149] In some embodiments, such as Figure 9 and Figure 10 As shown, the outer shell 412 is also provided with an inlet and outlet 4127, which are connected to the mounting cavity.

[0150] In this configuration, by providing an inlet and outlet 4127 on the shell wall of the outer shell 412, the material box 413 can be pushed into the mounting cavity through the inlet and outlet 4127 and can be pulled out from the mounting cavity through the inlet and outlet 4127. That is, the assembly between the material box 413 and the outer shell 412 is similar to a drawer-type structure, so that the material box 413 can be pulled out and assembled into the mounting cavity of the outer shell 412 through the inlet and outlet 4127.

[0151] The above structural design allows for a pull-out assembly structure between the material box 413 and the outer shell 412, which facilitates the removal and installation of the material box 413 from the outer shell 412 and makes it easier to replace the material box 413.

[0152] Optionally, the inlet / outlet 4127 is located on the shell wall of the outer casing 412 facing the door 12, which facilitates the disassembly and assembly of the material box 413.

[0153] Optionally, such as Figure 12 As shown, a handle 4136 is provided on the wall of the material box 413 facing the door 12, which facilitates the pulling operation of the material box 413.

[0154] Furthermore, such as Figure 6 As shown, when the material box 413 is assembled into the mounting cavity, the inlet and outlet 4127 are blocked by the material box 413.

[0155] With the above structural design, after the material box 413 is assembled into the installation cavity, the material box 413 can be used to block the inlet and outlet 4127, so that the water will not flow out from the inlet and outlet 4127, but will be guided to spray out from the first spray nozzle 4121 to directionally rinse the surface of the door seal ring 3.

[0156] Optionally, a sealing structure is provided on the outer periphery of the inlet / outlet 4127. After the material box 413 is assembled into the mounting cavity, the sealing structure can seal the gap between the material box 413 and the inlet / outlet 4127. The sealing structure can be a sealing strip.

[0157] Furthermore, a locking mechanism is provided between the material box 413 and the outer casing 412.

[0158] The locking mechanism is configured to lock the material box 413 to the housing 412 after the material box 413 is assembled in the mounting cavity, and to release the lock between the material box 413 and the housing 412 so that the material box 413 can be pulled out from the mounting cavity.

[0159] With the above structural design, after the material box 413 is assembled into the mounting cavity of the outer shell 412, the locking mechanism can be used to lock and fix the material box 413 to the outer shell 412, thereby improving the stability of the material box 413 after assembly and minimizing the risk of the material box 413 detaching from the outer shell 412 due to the impact of water flow; the locking mechanism can also be used to unlock the material box 413 from the outer shell 412, making it easy to remove the material box 413 from the outer shell 412.

[0160] For example, one specific structure of the locking mechanism may be: the locking mechanism includes a matching elastic block and a slot, one of which is disposed on the material box 413 and the other is disposed on the housing 412; when the material box 413 is fully pushed into the mounting cavity of the housing 412, the elastic block is placed into the slot and locks the material box 413 to the housing 412; when the material box 413 is pulled outward with appropriate external force, the elastic block can disengage from the slot to release the lock between the material box 413 and the housing 412, so that the material box 413 can be pulled out from the housing 412.

[0161] Of course, the specific structure of the locking mechanism is not limited to the above-mentioned elastic block and slot cooperation structure. For example, the locking mechanism can also be a screw or a pin. After the material box 413 is fully pushed into the mounting cavity of the housing 412, the material box 413 and the housing 412 can be locked by screws or pins. When it is necessary to remove the material box 413, the screws or pins can be removed first.

[0162] Furthermore, such as Figure 12 and Figure 13 As shown, the material box 413 includes a pick-up and put-out opening 4134 and a box cover 4135. The pick-up and put-out opening 4134 is opened on the box wall of the material box 413 and communicates with the receiving cavity. The box cover 4135 is adapted to the pick-up and put-out opening 4134 and can open or close the pick-up and put-out opening 4134, making the material box 413 an openable and closable structure.

[0163] With the above structural design, the bactericide and mold remover 4137 can be placed into or taken out of the receiving cavity through the inlet 4134 by opening the lid 4135, and the bactericide and mold remover 4137 can be confined within the receiving cavity of the material box 413 by closing the lid 4135. This structural design facilitates the replacement of the bactericide and mold remover 4137 in the material box 413. Moreover, when the bactericide and mold remover 4137 is ineffective or has a low effective ingredient content, it is not necessary to replace the entire material box 413; only the bactericide and mold remover 4137 in the receiving cavity needs to be replaced, which can save costs.

[0164] Optionally, the loading / unloading port 4134 is provided on the wall of the material box 413 facing the water inlet pipe 411.

[0165] Optionally, the lid 4135 can be part of the box wall, and water-permeable holes can be provided on the lid 4135.

[0166] Optionally, the lid 4135 and the opening 4134 can be connected by snap-fit, hinge, or other means.

[0167] Please refer to the above. Figures 7 to 9 , Figures 7 to 9 A schematic diagram of the external and internal structure of a nozzle mechanism is provided; it shows the structural relationship between the water inlet pipe, the outer shell and the material box, as well as the positions of the first water inlet and the second water inlet on the material box.

[0168] In some embodiments, such as Figures 7 to 9 As shown, the material box 413 has water permeable holes on its wall, including a first water permeable hole 4131 and a second water permeable hole 4132.

[0169] The first water-permeable hole 4131 is configured to connect the inner cavity of the receiving cavity and the water inlet pipe 411, and to confine the bactericidal and mildew-removing agent 4137 within the receiving cavity.

[0170] With the above structural design, by setting the first water permeable hole 4131, the water flow in the water inlet pipe 411 can be conveniently introduced into the receiving cavity of the material box 413 and come into contact with the built-in bactericidal and mildew-removing agent 4137, so as to release bactericidal and mildew-removing components in the water flow.

[0171] The second permeable hole 4132 is configured to connect the receiving cavity and the first spray port 4121, and to confine the bactericidal and mildew-removing agent 4137 within the receiving cavity.

[0172] With the above structural design, by setting the second water-permeable hole 4132, water containing sterilizing and mildew-removing ingredients can be easily introduced from the receiving cavity of the material box 413 to the first spray nozzle 4121, so as to spray onto the surface of the door seal ring 3.

[0173] It should be noted that the maximum aperture of the first water-permeable hole 4131 and the maximum aperture of the second water-permeable hole 4132 are both smaller than the particle size of the drug carrier skeleton of the bactericide and fungicide 4137, so as to ensure that the bactericide and fungicide 4137 and the drug carrier skeleton can always be confined within the receiving cavity of the material box 413, thereby preventing the bactericide and fungicide 4137 or the drug carrier skeleton from entering the space between the pipeline 43 or the nozzle mechanism 41 and the material box 413 and causing blockage, or preventing the bactericide and fungicide 4137 or the drug carrier skeleton from entering the door seal ring 3 or the cylinder assembly 2 and causing waste and contamination of the agent.

[0174] Please refer to the above. Figures 7 to 9 , Figures 7 to 9A schematic diagram of the external and internal structure of a nozzle mechanism is provided; it shows the structural relationship between the water inlet pipe, the outer shell and the material box, as well as the position of the first cavity within the nozzle mechanism.

[0175] In some embodiments, such as Figure 7 As shown, a first cavity 4123 is also formed inside the outer shell 412. The first cavity 4123 is connected to the mounting cavity and is located between the water inlet pipe 411 and the material box 413.

[0176] With the above structural design, the first cavity 4123 is formed inside the outer shell 412 and can be used as a buffer space between the water inlet pipe 411 and the material box 413. The first cavity 4123 can temporarily store the water flow entering the outer shell 412 from the water inlet pipe 411, and try to avoid the water flow directly entering the receiving cavity of the material box 413 through the first water permeable hole 4131, so as not to cause a large impact on the bactericidal and mildew-removing agent 4137 in the receiving cavity, and to break or quickly consume the bactericidal and mildew-removing components on the surface of the bactericidal and mildew-removing agent 4137, so that the bactericidal and mildew-removing components cannot be slowly released into the water flow and thus cause waste.

[0177] Optionally, such as Figure 7 As shown, there is one first cavity 4123, and the first cavity 4123 is located on top of the material box 413.

[0178] Furthermore, such as Figures 7 to 9 As shown, the material box 413 has a first water-permeable hole 4131 on its box wall facing the first cavity 4123.

[0179] Optionally, there are multiple first water-permeable holes 4131, which are arranged in an array on the box wall.

[0180] With the above structural design, combined with the first water-permeable hole 4131 opened on the material box 413, the first water-permeable hole 4131 is arranged in multiple ways. The water temporarily stored in the first cavity 4123 can enter the receiving cavity through multiple first water-permeable holes 4131. That is, the water can enter the receiving cavity from different positions and can be evenly and fully mixed with the bactericidal and mildew-removing agent 4137 in the receiving cavity, which is conducive to the better slow release of the bactericidal and mildew-removing components on the bactericidal and mildew-removing agent 4137 into the water.

[0181] Furthermore, the first water-permeable hole 4131 is located on the wall of the material box 413 facing the first cavity 4123, which can shorten the path of water flow in the first cavity 4123 into the receiving cavity of the material box 413, and can guide most of the water flow into the receiving cavity to come into contact with the bactericidal and mildew-removing agent 4137, so that the water flow can dissolve more bactericidal and mildew-removing components, which is beneficial to improving the bactericidal and mildew-removing effect on the door seal ring 3.

[0182] Please refer to the above. Figures 7 to 9 , Figures 7 to 9 A schematic diagram of the external and internal structure of a nozzle mechanism is provided; it shows the structural relationship between the water inlet pipe, the outer shell and the material box, as well as the position of the second cavity within the nozzle mechanism.

[0183] In some embodiments, such as Figure 7 As shown, a second cavity 4124 is also formed inside the outer shell 412. The second cavity 4124 is connected to the mounting cavity and is located between the first injection port 4121 and the material box 413.

[0184] With the above structural design, the second cavity 4124 is formed inside the outer shell 412 and is located between the material box 413 and the first spray nozzle 4121. The second cavity 4124 can temporarily store the water flow entering the outer shell 412 from the material box 413. The water flow in the material box 413 contains bactericidal and anti-mold ingredients. When the water flow containing bactericidal and anti-mold ingredients enters the second cavity 4124 through the second water permeable hole 4132, it can be further mixed so that the bactericidal and anti-mold ingredients can be more evenly and fully dissolved in the water flow before being sprayed out from the first spray nozzle 4121.

[0185] Optionally, such as Figure 7 As shown, there are two second cavities 4124, which are placed on both sides of the material box 413 along the left and right directions of the box 1.

[0186] Furthermore, such as Figures 7 to 9 As shown, the material box 413 has a second water-permeable hole 4132 on its box wall facing the second cavity 4124.

[0187] Optionally, there are multiple second water-permeable holes 4132, which are arranged in an array on the box wall.

[0188] With the above structural design, the second water-permeable hole 4132 is set on the box wall of the material box 413 facing the second cavity 4124, which can shorten the path of water flow in the receiving cavity of the material box 413 into the second cavity 4124, so that the water flow in the receiving cavity can be guided into the second cavity 4124 in a directional and rapid manner.

[0189] Optionally, the first spray port 4121 is located in the middle or lower part of the shell wall of the outer casing 412 along the top-bottom direction (height direction) of the housing 1; the volume of the second cavity 4124 decreases along the first direction, and the first direction is parallel to the radial direction of the door seal ring 3 and points from the water inlet pipe 411 to the outer casing 412.

[0190] By adopting the above structural design, the volume of the second cavity 4124 is reduced along the first direction, so that the water flow in the upper part of the second cavity 4124 can squeeze the water flow in the middle and lower parts of the second cavity 4124 to be ejected from the first spray port 4121, and the pressure of the ejected water flow can be increased, which is beneficial to removing foreign objects adhering to the door seal ring 3.

[0191] Furthermore, such as Figure 7 As shown, the interior of the outer shell 412 may simultaneously include a first cavity 4123 and a second cavity 4124, and a flow channel 4126 for water to flow through is provided between the first cavity 4123 and the second cavity 4124.

[0192] The outer shell 412 has a first cavity 4123 and a second cavity 4124 inside. Water in the first cavity 4123 can enter the receiving cavity of the material box 413 through the first water permeable hole 4131 and mix with the bactericidal and mildew-removing agent 4137, so that the bactericidal and mildew-removing components on the bactericidal and mildew-removing agent 4137 dissolve in the water. The water containing the bactericidal and mildew-removing components can enter the second cavity 4124 through the second water permeable hole 4132 and can be sprayed out from the first spray port 4121.

[0193] By adopting the above structural design, a flow passage 4126 is provided between the first cavity 4123 and the second cavity 4124, which can directly connect the first cavity 4123 and the second cavity 4124. This allows part of the water flow that enters the first cavity 4123 through the water inlet pipe 411 to directly enter the second cavity 4124 without passing through the inside of the material box 413 and to be sprayed out from the first spray nozzle 4121. The flow path of this part of the water flow in the nozzle mechanism 41 is reduced, which can enhance the impact force of the water flow when it is sprayed out from the first spray nozzle 4121, which is beneficial to removing foreign objects adhering to the door seal ring 3.

[0194] Furthermore, the water flow that enters directly from the first cavity 4123 into the second cavity 4124 can also impact the water flow that enters from the material box 413 into the second cavity 4124 (which contains antibacterial and antifungal ingredients), allowing the two water flows to mix thoroughly. This allows the antibacterial and antifungal ingredients to dissolve more evenly and fully in the water flow within the second cavity 4124 before being sprayed out from the first spray nozzle 4121.

[0195] Please refer to the above. Figure 2 , Figure 3 , Figure 7 and Figure 11 , Figure 2 and Figure 3 A schematic diagram of the external and internal structure of a washing machine is provided; it shows the positional relationship between the door seal ring and the cabinet, and the positional relationship between the nozzle mechanism and the door seal ring. Figure 7A front view sectional view of a nozzle mechanism is provided, showing the internal structure of the nozzle mechanism. Figure 11 A schematic diagram of the bottom of a nozzle mechanism is provided, showing the distribution of the first spray nozzle on the housing.

[0196] In some embodiments, such as Figure 2 , Figure 3 and Figure 7 As shown, the inlet 11 is located on the front end face of the housing 1, and the nozzle 21 is arranged directly opposite the inlet 11 along the front-back direction of the housing 1. The door seal ring 3 connects the inlet 11 and the nozzle 21. The outer shell 412 is located on the top inner side of the door seal ring 3; the outer shell 412 has multiple first spray nozzles 4121, and the multiple first spray nozzles 4121 are distributed on both sides of the outer shell 412 along the left-right direction of the housing 1.

[0197] By adopting the above structural design, by setting the outer shell 412 in the nozzle mechanism 41 on the top inner side of the door seal ring 3, and distributing multiple first spray nozzles 4121 along the left and right directions of the housing 1 on both sides of the outer shell 412, the water flow can first spray onto the top of the surface of the door seal ring 3 after passing through the first spray nozzles 4121, and then flow down from top to bottom along both sides of the surface, so as to thoroughly spray and rinse the surface of the door seal ring 3, thereby improving the cleaning effect.

[0198] It should be noted that, as Figure 11 As shown, multiple first spray nozzles 4121 can be provided on the same side of the outer casing 412. The multiple first spray nozzles 4121 located on the same side of the outer casing 412 can be distributed along the front and rear direction of the housing 1, so that the water flow sprayed onto the surface of the door seal ring 3 can cover the area of ​​the surface of the door seal ring 3 in the front and rear direction of the housing 1 as much as possible, so as to more thoroughly rinse the surface of the door seal ring 3 and improve the cleaning effect.

[0199] Of course, the multiple first spray nozzles 4121 located on the same side of the outer casing 412 can also be distributed along the top and bottom direction of the housing 1, and these multiple first spray nozzles 4121 face different areas on the surface of the door seal ring 3. This structural design allows each first spray nozzle 4121 to correspond to a certain area on the surface of the door seal ring 3 (this area is mainly distributed in the top area of ​​the surface of the door seal ring 3), and to perform directional flushing and cleaning on this area, which can improve cleaning efficiency and effect.

[0200] In some embodiments, the dispensing port 11 is disposed on the front end face of the housing 1, and the cylindrical opening 21 is arranged directly opposite the dispensing port 11 along the front-rear direction of the housing 1. The door sealing ring 3 is connected between the dispensing port 11 and the cylindrical opening 21. The outer shell 412 is disposed on the top inner side of the door sealing ring 3; the outer shell 412 has at least one first spray port 4121, and at least one first spray port 4121 is located on one side of the outer shell 412 along the left-right direction of the housing 1; that is, in the left-right direction of the housing 1, all the first spray ports 4121 on the outer shell 412 are located on the same side of the outer shell 412.

[0201] By adopting the above structural design, compared to a structure in which the first spray nozzle 4121 is distributed on different sides of the outer casing 412, the first spray nozzle 4121 is only provided on one side of the outer casing 412. This allows for a stronger impact force of the water jet ejected through the first spray nozzle 4121, and enables the water jet to be more concentrated in directional rinsing of a portion of the surface of the door seal ring 3, thereby improving cleaning efficiency and effectiveness. The so-called portion of the surface of the door seal ring 3 can be, but is not limited to, the portion of the door seal ring 3 that is prone to the adhesion of foreign matter and the growth of harmful microorganisms such as bacteria and mold.

[0202] It should be noted that a structure in which all the first spray nozzles 4121 are located on the same side of the outer casing 412 may result in incomplete cleaning of the surface of the door seal ring 3, leaving a portion of the door seal ring 3 without water flow or incomplete cleaning. To improve this problem, multiple nozzle mechanisms 41 can be provided on the door seal ring 3, with the first spray nozzle 4121 of each nozzle mechanism 41 facing different areas on the surface of the door seal ring 3. In addition, by using multiple nozzle mechanisms 41, without affecting the structural layout, each nozzle mechanism 41 can be arranged in a position adjacent to the portion of the door seal ring 3 that it can clean, thereby shortening the distance of the water flow from the first spray nozzle 4121 to the portion of the door seal ring 3 that the first spray nozzle 4121 faces, resulting in a stronger impact force of the water flow reaching the surface of the door seal ring 3, which can further improve cleaning efficiency and effect.

[0203] Please refer to the above. Figure 1 , Figure 2 , Figure 6 and Figure 7 , Figure 1 and Figure 2 A schematic diagram of the external structure of a washing machine is provided, showing the basic components of the washing machine. Figure 6 and Figure 7 A schematic diagram of the external and internal structure of a nozzle mechanism is provided; it shows the structural relationship between the water inlet pipe, the outer shell and the material box in the nozzle mechanism, as well as the position of the second spray nozzle on the outer shell.

[0204] In some embodiments, such as Figure 1 , Figure 2 and Figure 6 As shown, a door 12 is provided at the delivery port 11 of the housing 1, and the door 12 is configured to open or close the delivery port 11; a second spray port 4122 is also provided on the shell wall of the outer shell 412, the second spray port 4122 is connected to the mounting cavity, and the second spray port 4122 faces the inner surface of the door 12.

[0205] With the above structural design, by providing a second spray nozzle 4122 on the outer casing 412, the water inlet control unit 42 can control the water flow to enter the nozzle mechanism 41 through the pipe 43, and the water flow is sprayed out from the second spray nozzle 4122 toward the inner surface of the door body 12, which can rinse and clean the inner surface of the door body 12 and remove foreign matter adhering to the inner surface of the door body 12. Here, the inner surface of the door body 12 refers to the surface of the door body 12 inside the box body 1 after the dispensing port 11 of the box body 1 is closed.

[0206] Furthermore, such as Figure 7 As shown, a material box 413 containing a built-in bactericidal and mildew-removing agent 4137 is provided in the nozzle mechanism 41. The water-permeable hole on the material box 413 includes a third water-permeable hole 4133. The third water-permeable hole 4133 is configured to connect the receiving cavity and the second spray port 4122, and to confine the bactericidal and mildew-removing agent 4137 within the receiving cavity.

[0207] Under the control of the water inlet control unit 42, the water flowing out of the receiving cavity through the third water permeable hole 4133 is sprayed out through the second spray nozzle 4122 and sprayed onto the inner surface of the door body 12.

[0208] With the above structural design, the receiving cavity and the second spray nozzle 4122 are connected by a third water-permeable hole 4133. The water used to clean the inner surface of the door 12 can flow through the receiving cavity of the material box 413 and the bactericidal and mildew-removing agent 4137 inside the cavity. When the water flows over the surface of the bactericidal and mildew-removing agent 4137, the bactericidal and mildew-removing components on the bactericidal and mildew-removing agent 4137 can dissolve in the water flow and be sprayed onto the inner surface of the door 12 through the second spray nozzle 4122 along with the water flow. This can kill bacteria, mold and other harmful microorganisms attached to the inner surface of the door 12 while cleaning it, so as to prevent the inner surface of the door 12 from becoming moldy and producing odors, improve the user's experience of using the product and reduce the impact on the user's health.

[0209] It should be noted that the maximum aperture of the third permeable hole 4133 is smaller than the particle size of the drug carrier skeleton of the bactericide and fungicide 4137, so as to ensure that the bactericide and fungicide 4137 and the drug carrier skeleton can always be confined within the receiving cavity of the material box 413, thereby preventing the bactericide and fungicide 4137 or the drug carrier skeleton from entering the space between the pipeline 43 or the nozzle mechanism 41 and the material box 413 and causing blockage, or preventing the bactericide and fungicide 4137 or the drug carrier skeleton from entering the door seal ring 3 or the cylinder assembly 2 and causing waste and contamination of the agent.

[0210] refer to Figure 7 , Figure 7 A front view sectional view of a nozzle mechanism is provided, showing the position of the third cavity within the housing.

[0211] In some embodiments, such as Figure 7 As shown, a third cavity 4125 is also formed inside the outer shell 412. The third cavity 4125 is connected to the mounting cavity and is located between the second injection port 4122 and the material box 413.

[0212] With the above structural design, the third cavity 4125 is formed inside the outer shell 412 and is located between the material box 413 and the second spray nozzle 4122. The third cavity 4125 can temporarily store the water flow entering the outer shell 412 from the material box 413. The water flow in the material box 413 contains bactericidal and anti-mold ingredients. When the water flow containing bactericidal and anti-mold ingredients enters the third cavity 4125 through the third water permeable hole 4133, it can be further mixed so that the bactericidal and anti-mold ingredients can be more evenly and fully dissolved in the water flow before being sprayed out from the second spray nozzle 4122.

[0213] Optionally, such as Figure 7 As shown, there is one third cavity 4125, and the third cavity 4125 is located at the bottom of the material box 413.

[0214] Furthermore, such as Figure 7 As shown, a third water-permeable hole 4133 is provided on the wall of the material box 413 facing the third cavity 4125.

[0215] Optionally, there are multiple third permeable holes 4133, which are arranged in an array on the box wall.

[0216] With the above structural design, the third water-permeable hole 4133 is set on the box wall of the material box 413 facing the third cavity 4125, which can shorten the path of water flow in the receiving cavity of the material box 413 into the third cavity 4125, so that the water flow in the receiving cavity can be guided into the third cavity 4125 in a directional and rapid manner.

[0217] Please refer to the above. Figures 1 to 3 , Figure 6 , Figure 7 and Figure 11 , Figure 1 and Figure 2 A schematic diagram of the external structure of a washing machine is provided, showing the basic components of the washing machine. Figure 3 A schematic diagram of the internal structure of a washing machine is provided, showing a structural relationship in which a cleaning structure is installed inside the washing machine. Figure 6 and Figure 7 A schematic diagram of the external and internal structure of a nozzle mechanism is provided; it shows the structural relationship between the water inlet pipe, the outer shell and the material box in the nozzle mechanism, as well as the position of the second spray nozzle on the outer shell. Figure 11 A schematic diagram of the bottom of a nozzle mechanism is provided, showing the distribution of the second spray nozzle on the housing.

[0218] An embodiment of this disclosure also provides a washing machine, such as Figures 1 to 3 As shown, the washing machine includes a cabinet 1, a drum assembly 2, a door seal ring 3, and a cleaning structure 4.

[0219] The container 1 includes a dispensing port 11 and a door 12 for opening or closing the dispensing port 11. A cylindrical assembly 2 is located inside the container 1, having an opening 21 directly opposite the dispensing port 11. A door seal 3 is positioned between the dispensing port 11 and the opening 21, sealing the gap between them. A cleaning structure 4 cleans the inner surface of the door 12 and simultaneously provides antibacterial and anti-mold components to remove foreign matter adhering to the inner surface and kill bacteria, mold, and other harmful microorganisms. It should be understood that the inner surface of the door 12 refers to the surface of the door 12 inside the container 1 after the dispensing port 11 is closed.

[0220] Among them, such as Figure 3 As shown, the cleaning structure 4 includes a nozzle mechanism 41, a water inlet control unit 42, and a pipe 43 connecting the nozzle mechanism 41 and the water inlet control unit 42.

[0221] Specifically, such as Figure 6 , Figure 7 and Figure 11As shown, the nozzle mechanism 41 includes a water inlet pipe 411, a housing 412, and a material box 413. The water inlet pipe 411 passes through the door seal ring 3; the housing 412 is located inside the door seal ring 3, and an installation cavity is formed inside the housing 412, which is connected to the pipe 43 through the water inlet pipe 411. A second spray port 4122 connected to the installation cavity is provided on the housing wall of the housing 412, and the second spray port 4122 faces the inner surface of the door body 12; the material box 413 is detachably disposed in the installation cavity, and an accommodating cavity for holding the bactericidal and mildew-removing agent 4137 is formed inside the material box 413. A third water permeable hole 4133 is provided on the box wall of the material box 413. To connect the receiving cavity and the second spray port 4122, and to confine the bactericidal and mildew-removing agent 4137 within the receiving cavity, the water inlet control unit 42 is configured to control the water flow to enter the housing 412 through the pipe 43 and the water inlet pipe 411, and to spray out from the second spray port 4122. At least a portion of the water flow enters the receiving cavity, causing at least a portion of the bactericidal and mildew-removing components on the bactericidal and mildew-removing agent 4137 to dissolve in the water flow. The water flow containing the bactericidal and mildew-removing components can flow out from the receiving cavity through the third water permeable hole 4133 and be sprayed onto the inner surface of the door 12 through the second spray port 4122.

[0222] With the above structural design, a cleaning structure 4 is added. In the cleaning structure 4, the nozzle mechanism 41 is connected to the water inlet control unit 42 through the pipe 43. The water inlet control unit 42 can control the water flow to enter the nozzle mechanism 41 through the pipe 43 and make the water flow spray out from the second spray port 4122 toward the inner surface of the door body 12, which can rinse and clean the inner surface of the door body 12 and remove foreign objects adhering to the inner surface of the door body 12.

[0223] Furthermore, the nozzle mechanism 41 is equipped with a container 413 containing a built-in bactericidal and mildew-removing agent 4137. The water flow used to clean the inner surface of the door 12 can flow through the receiving cavity of the container 413 and the bactericidal and mildew-removing agent 4137 inside the cavity. When the water flows over the surface of the bactericidal and mildew-removing agent 4137, the bactericidal and mildew-removing components on the bactericidal and mildew-removing agent 4137 can dissolve in the water flow and be sprayed onto the inner surface of the door 12 through the second spray nozzle 4122 along with the water flow. This can kill bacteria, mold and other harmful microorganisms attached to the inner surface of the door 12 while cleaning the inner surface of the door 12, so as to prevent the inner surface of the door 12 from becoming moldy and producing odors, improve the user's experience of using the product and reduce the impact on the user's health.

[0224] In addition, since the outer casing 412 is located inside the door seal ring 3, and the feed box 413 is detachably disposed in the mounting cavity of the outer casing 412, the feed box 413 can be exposed inside the door seal ring 3. When the feed box 413 needs to be replaced, it can be accessed after opening the door 12, which facilitates the replacement of the feed box 413. This allows the bactericidal and mildew-preventing agent 4137 in the feed box 413 to continuously and stably provide sufficient bactericidal and mildew-preventing ingredients and release them slowly into the water flow. This ensures that the door 12 and the washing machine maintain a good bactericidal and mildew-preventing effect throughout the entire life cycle of the washing machine, better meeting the long-term health needs of users.

[0225] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and not to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
