Description

TECHNICAL FIELD

[0001] Some embodiments of the present application relate to the technical field of household appliances, and particularly to a pulsator washing machine. BACKGROUND

[0002] A pulsator washing machine is a cleaning appliance that uses electric energy to produce mechanical action to wash clothes.

[0003] A control panel is an important component of a pulsator washing machine, and the control panel includes a device mounting portion and a circuit board located inside a baffle. The baffle is provided with a movable member such as a knob or a button, and the movable member is connected to an encoder control rod of the circuit board to input a control signal to the circuit board through the movable member.

[0004] However, water flow is easy to enter the inside of the baffle from the outside of the baffle, causing the circuit board to be damp or short-circuited. CONTENT OF THE INVENTION

[0005] Some embodiments of the present application provide a pulsator washing machine, which can solve the problem that water flow enters the inside of the baffle from the outside of the baffle, causing the circuit board to be damp or short-circuited.

[0006] In a first aspect, some embodiments of the present application provide a pulsator washing machine, comprising:

[0007] a cabinet;

[0008] a baffle frame provided on the top of the cabinet, the baffle frame having a dropping opening; the baffle frame is provided with a liquid collecting groove, and the liquid collecting groove has a liquid guide outlet;

[0009] a drum assembly provided in the cabinet, the drum assembly having a washing cavity, and a drum opening of the drum assembly is communicated with the washing cavity and faces the dropping opening;

[0010] a water box for communicating with a water inlet of the pulsator washing machine, the water box being communicated with the liquid guide outlet; the water box is provided with a communication opening, and the communication opening is communicated with the washing cavity;

[0011] a control panel, the control panel comprising:

[0012] a device mounting portion provided on the top of the baffle frame; the device mounting portion is provided with a mounting opening;

[0013] a circuit board provided in the device mounting portion, the circuit board having a rotatable encoder control rod;

[0014] A knob support is disposed on the circuit board. The knob support is provided with a flow guide structure, which is annularly arranged around the periphery of the encoder control rod. At least part of the opening of the flow guide structure is directed towards the mounting port for receiving water flow from the mounting port into the flow guide structure. The flow guide structure has a flow guide outlet through which water flowing through the flow guide structure can enter the liquid collection tank.

[0015] A knob is connected to the encoder control rod through the mounting port. The knob is movably arranged on the knob support to drive the encoder control rod to rotate relative to the circuit board.

[0016] The impeller washing machine of some embodiments of the present application can guide and discharge water entering the enclosure by arranging a flow guide structure on the knob support. Water entering the enclosure through the mounting port will enter the flow guide structure. The flow guide structure is annularly arranged around the periphery of the encoder control rod, so that the flow guide structure can guide water flow from the periphery of the encoder control rod, avoiding water flow to the encoder, thereby achieving the waterproof effect of the encoder. Moreover, water in the flow guide structure will be discharged to the liquid collection tank of the enclosure through the flow guide outlet, and will not accumulate inside the flow guide structure, effectively avoiding water flow to the circuit board or other components, thereby achieving the waterproof effect of the circuit board and other components.

[0017] The arrangement of the liquid collection tank ensures the centralized collection and discharge of water. The liquid outlet of the liquid collection tank can provide a safe drainage path, so that water in the liquid collection tank can be guided into the water box for storage and reuse.

[0018] The water box serves as an intermediate storage and regulation device, which can receive and store water and release water when needed, helping to better control the use and distribution of water during the washing process. The design of the communication port allows water in the water box to be directly introduced into the washing cavity, combined with the water flow during the washing process, ensuring smooth and safe water flow. In addition, the water is finally discharged into the washing cavity, which can also prevent water from flowing to the ground, reducing the risk of electric shock and improving safety.

[0019] In this way, the impeller washing machine realizes reliable operation in a humid environment, reduces the risk of short circuit and moisture, and improves the safety and durability of the washing machine.

[0020] In some embodiments of the present application, the flow guide structure comprises:

[0021] A first flow guide channel is annularly arranged around the periphery of the encoder control rod.

[0022] A second flow guide channel, the first end of the second flow guide channel is in communication with the bottom of the first flow guide channel, and the second end of the second flow guide channel has the flow guide outlet.

[0023] In this way, by arranging the first flow guide channel around the encoder control rod, water droplets are guided into the channel when they come into contact with the knob support, avoiding direct contact with the components inside the enclosure, effectively reducing the risk of moisture penetration. The design of the second flow guide channel provides a clear drainage path for water flow. The first end of the second flow guide channel is in communication with the bottom of the first flow guide channel, ensuring that water can smoothly enter the second flow guide channel. The second end of the second flow guide channel is provided with a flow guide outlet that is in communication with the washing cavity, allowing water to be safely drained. This design not only prevents water accumulation, but also ensures effective water drainage.

[0024] By arranging the first and second flow guide channels, a multi-level waterproof structure is provided, significantly enhancing the waterproof performance of the impeller washing machine in a humid environment. The first flow guide channel provides preliminary water flow guidance, while the second flow guide channel ensures effective water drainage. This dual flow guide design effectively prevents moisture from affecting the circuit board and components, reducing the risk of short circuits and moisture, and improving the reliability and service life of the washing machine.

[0025] In some embodiments of the present application, the device mounting portion is provided with a water blocking protrusion, which is annularly arranged in the mounting opening, and the inner side of the water blocking protrusion is used to pass through the encoder control rod;

[0026] In a direction away from the circuit board, the water blocking protrusion is protrudingly arranged relative to the device mounting portion.

[0027] In this way, the annular and protruding water blocking protrusion not only prevents moisture from entering the enclosure interior through the mounting opening, but also guides water flow away from the mounting opening using its annular physical shape, providing an effective waterproof barrier that can reduce the risk of water entering the enclosure interior through the mounting opening, causing short circuits and moisture in the circuit board and components.

[0028] In some embodiments of the present application, the control panel further comprises:

[0029] An encoder support is arranged in the device mounting portion;

[0030] The encoder support is provided with a fixing cavity; the circuit board is located in the fixing cavity, and the circuit board is connected with the encoder support.

[0031] In this way, the encoder support provides a stable and safe mounting environment for the circuit board, reducing the influence of external factors on the circuit board.

[0032] In some embodiments of the present application, the encoder support is provided with a first clamping interface;

[0033] The knob support is provided with a fourth clamping part; the fourth clamping part passes through the circuit board, and the fourth clamping part is clamped with the first clamping interface.

[0034] In this way, the clamping design of the encoder support and the knob support provides a simplified assembly mode, reduces the dependence on traditional fasteners, improves the assembly efficiency and the stability of the connection. In addition, the knob support and the circuit board are mounted on the encoder support, and the integration degree is high, so that modular assembly and installation can be realized, which helps to improve the production efficiency.

[0035] In some embodiments of the present application, the knob support is provided with a fifth limiting part, and the fifth limiting part is arranged in the circuit board.

[0036] In this way, the fifth limiting part can limit the installation of the knob support on the encoder support according to the preset position, so as to ensure that the water diversion and drainage direction of the water diversion structure on the knob support is correct, that is, the water diversion outlet is located at the bottom of the water diversion structure, so as to facilitate the water collected in the water diversion structure to flow to the water diversion outlet under the action of gravity.

[0037] In some embodiments of the present application, the knob support is provided with an annular limiting part, and the annular limiting part is located on the inner side of the water diversion structure.

[0038] The knob is provided with a third clamping part, and the third clamping part is clamped with the annular limiting part.

[0039] In this way, after the annular limiting part is connected with the knob, the movement track of the knob can be ensured to be stable. The annular limiting part is located on the inner side of the water diversion structure, so that the outer side wall of the annular limiting part can serve as the side wall of the first water diversion channel, so that the water in the first water diversion channel cannot enter the annular limiting part, and effective waterproof protection can be provided for the encoder control rod. In addition, the knob is clamped and connected with the knob support, which provides a simplified assembly mode, reduces the dependence on traditional fasteners, improves the assembly efficiency and the stability of the connection.

[0044] A water box is configured to communicate with the water inlet end of the impeller washing machine, and the water box is in communication with the liquid outlet;

[0045] A control panel is included.

[0046] A device mounting portion is provided on the top of the enclosure, and the device mounting portion is provided with a mounting opening.

[0047] A circuit board is provided in the device mounting portion, and the circuit board has a rotatable encoder control lever.

[0048] A knob support is provided on the circuit board.

[0049] A knob is connected to the encoder control lever through the mounting opening, and the knob is movably arranged in the knob support to drive the encoder control lever to rotate relative to the circuit board.

[0050] The knob support is provided with a flow guide structure between the mounting opening and the circuit board. The flow guide structure is configured to receive water flow from the mounting opening and guide the water flow through the enclosure and the water box into the washing cavity.

[0051] The impeller washing machine of some embodiments of the present application has a flow guide structure provided on the knob support between the mounting opening and the circuit board. Water entering the enclosure through the mounting opening will enter the flow guide structure. The flow guide structure is arranged around the periphery of the encoder control lever, so that the flow guide structure can guide the water flow from the periphery of the encoder control lever, avoiding water flow to the encoder, and achieving the waterproof effect of the encoder. Moreover, the water in the flow guide structure will be discharged through the flow guide outlet to the liquid collection tank of the enclosure, avoiding water flow to the circuit board or other components, and achieving the waterproof effect of the circuit board and other components.

[0052] The provision of the liquid collection tank ensures the centralized collection and discharge of water. The liquid outlet of the liquid collection tank can provide a safe drainage path, so that the water in the liquid collection tank can be guided into the water box for storage and reuse. The water box, as an intermediate storage and adjustment device, can receive and store water, and release water when needed, helping to better control the use and distribution of water during the washing process. The design of the communication opening allows water in the water box to be directly introduced into the washing cavity, combined with the water flow during the washing process, ensuring smooth and safe water flow. In addition, the water is discharged into the washing cavity, which can also prevent water from flowing to the ground, reducing the risk of electric shock and improving safety.

[0053] The flow guide structure realizes water flow guide and discharge into the enclosure, effectively reduces the risk of water seeping into the circuit board and components, reduces the possibility of short circuit and damp, and improves the safety and durability of the washing machine.

[0122] In order to make the purpose, implementation and advantages of the present application more clear, the following will combine the drawings in some exemplary embodiments of the present application to clearly and completely describe the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only some of the embodiments of the present application, but not all of the embodiments.

[0126] The terms "first", "second", and the like are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0127] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0128] The technical solutions in some embodiments of the present application will be described clearly and completely in the following description of some embodiments of the present application in combination with the drawings in some embodiments of the present application. Obviously, some of the described embodiments are only some of the embodiments of the present application, not all of the embodiments. Based on some embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within the scope of protection of the present application.

[0129] As described in the background, the relevant technology is a cleaning electric appliance that uses electrical energy to generate mechanical action to wash clothes.

[0130] It is easy to understand that the control panel is an important part of the pulsator washing machine, and the control panel usually includes a device mounting portion and a circuit board located inside the enclosure. The enclosure is provided with a movable member such as a rotary knob or a button, and the movable member is connected with an encoder control rod of the circuit board to input a control signal to the circuit board through the movable member.

[0131] However, in order to enable the rotary knobs to be smoothly operated from the outside, the enclosure inevitably needs to be provided with a corresponding installation opening to enable the rotary knobs to protrude from the surface of the enclosure. However, in the daily use environment of the pulsator washing machine, water stains may be inadvertently splashed onto the control panel due to frequent contact with water sources, and then penetrate into the inside of the enclosure through the installation opening. Once the water contacts the circuit board and the encoder and other important components thereon, serious problems such as dampness and short circuit may be caused, thereby seriously interfering with the normal operation of the pulsator washing machine.

[0132] Therefore, some embodiments of the present application provide a pulsator washing machine, which comprises a cabinet, an enclosure provided on the top of the cabinet, the enclosure having a liquid collecting groove and a liquid guide outlet, a drum assembly arranged in the cabinet, the drum assembly having a washing cavity, a drum opening of the drum assembly being communicated with the washing cavity and facing a dropping opening, and a water box, the water box being provided with a communicating opening, the water box being communicated with the liquid guide outlet and the washing cavity through the communicating opening.

[0133] The pulsator washing machine further comprises a control panel, the control panel including a device mounting portion, a circuit board, a rotary knob support and a rotary knob. The device mounting portion is arranged on the top of the enclosure, and the device mounting portion is provided with an installation opening. The circuit board is arranged on the side of the device mounting portion facing the enclosure, and the circuit board has a rotatable encoder control rod. The rotary knob support is arranged on the side of the circuit board facing the device mounting portion. The rotary knob is connected with the encoder control rod through the installation opening, and the rotary knob is movably arranged on the rotary knob support to drive the encoder control rod to rotate relative to the circuit board.

[0134] For the waterproof aspect of the pulsator washing machine, the rotary knob support is provided with a flow guide structure, the flow guide structure being annularly arranged around the periphery of the encoder control rod, at least part of the flow guide structure facing the installation opening, and the flow guide structure having a flow guide outlet communicated with the liquid collecting groove. By arranging the flow guide structure on the rotary knob support, water entering the inside of the enclosure can be guided and discharged.

[0135] Water entering the inside of the enclosure through the installation opening can enter the flow guide structure, so that the water flow can be prevented from reaching the encoder, thereby achieving the waterproof effect of the encoder. Moreover, the water in the flow guide structure can be discharged to the liquid collecting groove through the flow guide outlet, so that the water flow can be prevented from reaching the circuit board or other components, thereby achieving the waterproof effect of the circuit board and other components.

[0136] The water entering the sump can be guided into the water box for storage or reuse. The water box, as an intermediate storage and regulating device, can receive and store the incoming water and release the water when needed, helping to better control the use and distribution of water during the washing process.

[0137] The water entering the water box can be directly introduced into the washing cavity and merged with the water flow during the washing process, ensuring smooth and safe water flow. In addition, the water is discharged into the washing cavity, which can also prevent water from flowing to the ground, reducing the risk of electric shock and improving safety.

[0138] In combination with Figure 1 and Figure 2 It is shown that some embodiments of the present application provide a pulsator washing machine.

[0139] The pulsator washing machine includes a cabinet 10. The top of the cabinet 10 has a drop port 121. The drop port 121 is used for dropping clothes. The cabinet 10 includes a box body 11 and a surrounding frame 12. Among them, the surrounding frame 12 can be used for clothes dropping. The surrounding frame 12 can also be used to support and connect other components. The surrounding frame 12 is arranged on the top of the box body 11, and the surrounding frame 12 has a drop port 121. The drop port 121 can be used for dropping clothes.

[0140] It should be noted that the cabinet 10 has oppositely arranged left and right side walls 14 and 15 in the depth direction, and oppositely arranged front and rear end faces 13. The front end face of the cabinet 10 faces Figure 1 the Z1 direction, and the rear end face 13 of the cabinet 10 faces away from Figure 1 the Z1 direction; the right side wall 15 of the cabinet 10 faces Figure 1 the X1 direction, and the left side wall 14 of the cabinet 10 faces away from Figure 1 the X1 direction.

[0141] In combination with Figure 2 It is shown that in some embodiments, the pulsator washing machine further includes a drum assembly. The drum assembly is the core part of the washing process of the pulsator washing machine. The drum assembly is arranged in the cabinet 10, and the drum assembly has a washing cavity 20. The washing cavity 20 can be used to contain water and clothes. The drum port of the drum assembly is in communication with the washing cavity 20 and faces the drop port 121, so that the clothes dropped through the drop port 121 can enter the washing cavity 20 for cleaning.

[0142] The drum assembly includes an outer drum. The outer drum is arranged in the box body 11, and the drum port of the outer drum faces the drop port.

[0143] The drum assembly includes an inner drum 200. The inner drum 200 is rotatably arranged in the outer drum, and the drum opening of the inner drum 200 can also be directed towards the clothes loading / unloading opening. The drum opening of the inner drum 200 is in communication with the washing cavity 20, so that the drum opening of the drum assembly is in communication with the washing cavity 20. The inner drum 200 has the washing cavity 20. During the process of washing clothes, the inner drum 200 can rotate relative to the outer drum to wash the clothes in the washing cavity 20.

[0144] A plurality of communication holes can be arranged on the drum wall of the inner drum 200. The communication holes are used to communicate the washing cavity 20 and the interior of the outer drum, so that the liquid in the washing cavity 20 can flow into the outer drum through the communication holes, so as to be discharged from the outer drum after washing is completed.

[0145] Referring to Figure 2 As shown in some embodiments, the pulsator washing machine further includes a door cover assembly. The door cover assembly is arranged on the top of the cabinet 10 and can open or close the loading opening 121. When the door cover assembly opens the loading opening 121, it can facilitate the user to load clothes at the loading opening 121. When the door cover assembly closes the loading opening 121, it can cover the loading opening 121 to enhance the safety of the pulsator washing machine when it is running.

Figure 1 An enlarged view of the pulsator washing machine at A, Figure 4 As shown in some embodiments, the pulsator washing machine further includes a door cover assembly. The door cover assembly is arranged on the top of the cabinet 10 and can open or close the loading opening 121. When the door cover assembly opens the loading opening 121, it can facilitate the user to load clothes at the loading opening 121.

Figure 2 A structural schematic view of the pulsator washing machine from another perspective, Figure 5 A schematic view of the installation of the damper 50 provided by some embodiments of the present application on the top of the cabinet 10. Figure 6 An installation exploded view of the damper 50 on the top of the cabinet 10 is shown. Figure 7 A schematic view of the installation of the damper 50 on the top of the cabinet 10 is shown. Among them, Figure 5 to Figure 7 Some structures of the pulsator washing machine on the top of the cabinet 10 are hidden. For example, Figure 4 And Figure 5 The door cover 40 in the door cover assembly is hidden in some embodiments.

[0147] Referring to Figure 3 to Figure 7 The structure of the pulsator washing machine is further described.

[0148] Referring to Figure 3 to Figure 6As shown, in some embodiments, the door cover assembly comprises a mounting member 30. The mounting member 30 is arranged on the top of the cabinet 10 and cooperates with the top of the cabinet 10 to define a limiting groove 60. That is, the mounting member 30 cooperates with the surrounding frame 12 to define the limiting groove 60. For example, the mounting member 30 can comprise a mounting portion 31 arranged on the top of the cabinet 10 and cooperates with the top of the cabinet 10 to define the limiting groove 60. The surrounding frame 12 has a groove on the side away from the box body 11, the mounting portion 31 is arranged in the groove, and the mounting portion 31 and the portion of the surrounding frame 12 provided with the groove can jointly enclose the limiting groove 60.

[0149] As shown in Figure 6 and Figure 7 As shown, the surrounding frame 12 also has a mounting groove (not labeled) on the side away from the box body 11, and the mounting portion 31 can be mounted in the mounting groove and connected with the surrounding frame 12 by fasteners or the like to arrange the mounting portion 31 on the top of the cabinet 10 while reducing the mounting height of the mounting member 30 on the surrounding frame 12. The fastener can be a connecting structure such as a screw or a bolt.

[0150] Alternatively, the mounting member 30 can also be arranged on the top of the cabinet 10 by other means. For example, the mounting member 30 can be arranged on the top of the cabinet 10 by clamping.

[0151] As shown in Figure 3 and Figure 4 As shown, the door cover assembly further comprises a door cover 40. The door cover 40 is rotationally connected with the mounting member 30. The door cover 40 can open or close the drop opening 121 when it rotates relative to the mounting member 30, thereby realizing the function of opening or closing the drop opening 121 of the door cover assembly.

[0152] In some embodiments, the mounting member 30 can comprise a connecting portion 32. The connecting portion 32 can be arranged on the side of the mounting portion 31 away from the surrounding frame 12. The door cover 40 has a avoiding groove at a position corresponding to the connecting portion 32, the connecting portion 32 is arranged in the avoiding groove, and the two ends of the connecting portion 32 can be directly or indirectly rotationally mounted on the groove wall of the avoiding groove through other adapters, thereby realizing the rotational connection between the door cover 40 and the mounting member 30. The door cover 40 can rotate around the connecting portion 32 when it rotates relative to the mounting member 30, thereby opening or closing the drop opening 121.

[0153] To meet the demand of people for large capacity of the pulsator washing machine, the size of the cabinet 10 and the door cover 40 will also be larger. This will result in a heavier door cover 40, and if the closing speed of the door cover 40 is too fast during the closing process, it will impact the top of the cabinet 10 and easily cause abnormal noise, affecting the user experience.

[0154] To improve the user experience, as shown in Figure 4 to Figure 7As shown, the door cover assembly further comprises a damper 50. The damper 50 is installed in the limiting groove 60, so that the door cover 40 can push the damper 50 during the process of rotating and closing the door cover 40 relative to the cabinet 10. The pushed damper 50 can provide damping force for the closing of the door cover 40, so as to reduce the closing speed of the door cover 40 and achieve the slow descending function of the door cover 40, thereby avoiding abnormal sound during the closing process of the door cover 40 and improving user experience.

[0155] For the convenience of users, see Figure 4 As shown, the door cover 40 is arranged on one side of the top of the cabinet 10 adjacent to the rear end surface 13 of the cabinet 10. Therefore, the limiting groove 60 is also arranged on one side of the top of the cabinet 10 adjacent to the rear end surface 13 of the cabinet 10, so that the damper 50 can be pushed by the door cover 40 during the rotation of the door cover 40 relative to the cabinet 10, and the slow descending function of the door cover 40 is achieved.

[0156] It should be noted that when the door cover 40 is arranged on one side of the top of the cabinet 10 adjacent to the left side wall 14 or the right side wall 15, if the slow descending function of the door cover 40 is required, the limiting groove 60 will also be arranged on one side of the top of the cabinet 10 adjacent to the left side wall 14 or the right side wall 15 of the cabinet 10, so that the damper 50 can be installed on the top of the cabinet 10 and be pushed by the door cover 40 during the rotation of the door cover 40.

[0157] Hereinafter, the structure of the pulsator washing machine will be further described by taking the limiting groove 60 arranged on one side of the top of the cabinet 10 adjacent to the rear end surface 13 of the cabinet 10 as an example.

[0158] For the convenience of users, see Figure 5 to Figure 7 As shown, in some embodiments, the damper 50 comprises a damper body. The damper body is arranged in the limiting groove 60, and the damper body is located at one end of the limiting groove 60 away from the door cover 40. For example, the damper body can be clamped in the limiting groove 60 to fix the damper body in the limiting groove 60.

[0159] The damper 50 further comprises a damping member 52. The damping member 52 is located in the limiting groove 60, and the damping member 52 is located at one end of the limiting groove 60 close to the door cover 40, and the damping member 52 is connected with the damper body. The door cover 40 is configured to push the damping member 52 to move in the limiting groove 60 towards the damper body when the door cover 40 rotates relative to the mounting member 30, so as to limit the rotation of the door cover 40. Specifically, when the damping member 52 moves in the limiting groove 60 towards the damper body, the rotation of the door cover 40 can be limited by the damping member 52.

[0160] By limiting the rotation of the door cover 40 by the damping member 52, the speed of the door cover 40 during the closing process can be reduced, the slow descending function of the door cover 40 is achieved, thereby avoiding abnormal sound during the closing process of the door cover 40 and improving user experience.

[0161] For the convenience of users, see Figure 5As shown, when the mounting portion 31 is arranged on the top of the cabinet 10, the mounting portion 31 can also extend towards the direction of the limiting groove 60 to shield part of the opening of the limiting groove 60. At this time, the mounting portion 31 can also limit the damper body in the limiting groove 60. For example, the side of the mounting portion 31 towards the damper body can have a clamping groove, and part of the damper body can be arranged in the clamping groove, so that the mounting portion 31 can limit the damper body in the limiting groove 60.

[0162] Referring to Figure 5 to Figure 7 As shown, the damper body can include a cylinder 51 and a damping medium. The damping medium is arranged in the cylinder 51.

[0163] The damper 50 also includes a connecting piece 53. One end of the connecting piece 53 is arranged in the cylinder 51, and the other end is connected with the damping piece 52. When the damping piece 52 is pushed, the damping piece 52 can move towards the cylinder 51 and push the connecting piece 53, so that the connecting piece 53 can move with the damping piece 52 to compress the damping medium.

[0164] After the damping medium is compressed, a damping force is generated, which is transmitted to the damping piece 52 through the connecting piece 53, so that the damping piece 52 transmits the damping force to the door cover 40. The damping force acts as resistance to the continued rotation of the door cover 40, which can limit the rotational closing of the door cover 40 to reduce the closing speed of the door cover 40 and achieve the slow descent function of the door cover 40.

[0165] Referring to Figure 3 and Figure 5 As shown, in some embodiments, the door cover 40 can have an abutting portion 41 on the side towards the top of the cabinet 10. When the door cover 40 is rotated relative to the cabinet 10 and opened to the maximum position, the abutting portion 41 is separated from the damping piece 52.

[0166] During the process of the rotational closing of the door cover 40 relative to the cabinet 10, the abutting portion 41 can be rotated into the limiting groove 60 and contact the end of the damping piece 52 away from the damper body during the rotation of the door cover 40.

[0167] With the continued closing of the door cover 40, the abutting portion 41 will push the damping piece 52 and the connecting piece 53 to move in the limiting groove 60 towards the cylinder 51 to compress the damping medium. The damping force generated by the damping medium is transmitted to the abutting portion 41 through the connecting piece 53 and the damping piece 52. The damping force acts as resistance to the continued rotation of the abutting portion 41, which can limit the rotational closing of the door cover 40 to reduce the closing speed of the door cover 40 during the closing process and achieve the slow descent function of the door cover 40.

[0168] In some embodiments, when the door cover 40 is rotated by a preset angle from the open-to-maximum position to the side facing the drop opening 121 relative to the cabinet 10, the abutting portion 41 can be in contact with the damping member 52 away from the damping member body. That is, in the initial stage of the rotation of the door cover 40 from the open-to-maximum position to the side facing the drop opening 121, the abutting portion 41 is in contact with the damping member 52, so as to realize the slow closing function of the door cover 40. The pulsator washing machine uses other damping members 52 to provide damping force in the initial stage of the rotation of the door cover 40 from the open-to-maximum position to the side facing the drop opening 121, which can effectively reduce the closing speed of the door cover 40 before the abutting portion 41 is in contact with the damping member 52, so as to ensure the damping effect of the damper 50, and at the same time, the service life of the damper 50 can be improved.

[0169] The preset angle can be 25° to 33°, etc. For example, the preset angle can be 28°, 29°, 30°, etc.

[0170] When the damper 50 is pushed, the damper 50 is prone to bending deformation under the pushing of the abutting portion 41, so as to cause problems such as unstable damping force, which affects the slow closing function of the door cover 40. Moreover, when the damper 50 is bent and deformed, noise is generated, which shortens the service life of the damper 50 and causes other adverse problems.

[0171] Therefore, the bending deformation of the damper 50 needs to be controlled.

[0172] The researchers found that the reason why the damper 50 is bent and deformed under the pushing of the abutting portion 41 is that the damper 50 moves toward the slot width or slot depth direction of the limiting slot 60 under the pushing of the abutting portion 41. For example, when the damper 50 moves toward the slot width direction of the limiting slot 60 under the pushing of the abutting portion 41, the damper 50 will be bent and deformed along the slot width direction. For example, when the damper 50 moves toward the slot depth direction of the limiting slot 60 under the pushing of the abutting portion 41, the damper 50 will be bent and deformed along the slot depth direction.

[0173] When the movement of the damper 50 toward at least one of the slot width and slot depth direction of the limiting slot 60 under the pushing of the abutting portion 41 is limited, the bending deformation of the damper 50 can be improved.

[0174] Therefore, the pulsator washing machine provided by some embodiments of the present application improves the structure of at least one of the damping member 52 and the mounting member 30, so as to limit the movement of the damper 50 toward at least one of the slot width and slot depth direction of the limiting slot 60 under the pushing of the abutting portion 41, to improve the bending deformation of the damper 50, so as to reduce the bending deformation of the damper 50, to avoid problems such as unstable damping force, noise generation, service life shortening, etc. of the damper 50, to enhance the stability of the slow closing function of the door cover 40, and at the same time, the service life of the damper 50 can be improved, and the noise generated by the damper 50 can be reduced.

[0175] It should be noted that the slot width direction and the slot depth direction of the limiting slot 60 are perpendicular to the moving direction of the damping member 52. The moving direction of the damping member 52 refers to the direction in which the damping member 52 moves towards the damper body, which can be seen as the X direction. The slot width direction of the limiting slot 60 can be seen as the Y direction. The slot depth direction of the limiting slot 60 can be seen as the Z direction.

[0176] The improvement of the damping member 52 will be further described below in combination with the accompanying drawings and some embodiments.

[0177] Figure 8 A structural schematic view of a damper 50 is shown in a first perspective view, Figure 9 A partial view of a damper 50 in a limiting slot 60 is shown.

[0178] Referring to Figure 8 and Figure 9 As shown, the damping member 52 has a protruding first limiting portion 521 on the side wall facing the limiting slot 60. For example, the first limiting portion 521 can be arranged on the side wall of the damping member 52 along the slot width direction of the limiting slot 60, so that the first limiting portion 521 faces the side wall of the limiting slot 60. There is a gap between the first limiting portion 521 and the side wall of the limiting slot 60. The first limiting portion 521 is used to limit the movement of the damping member 52 towards the side wall of the limiting slot 60.

[0179] On the basis of the unchanged slot width of the limiting slot 60, by arranging the first limiting portion 521, the gap between the position of the first limiting portion 521 and the side wall of the limiting slot 60 can be reduced. In this way, during the movement of the damping member 52 towards the damper body, if the damping member 52 is still moved towards the side wall of the limiting slot 60 under the pushing of the door cover 40, the first limiting portion 521 will be in contact with the side wall of the limiting slot 60 in priority to the rest of the damping member 52, so as to limit the movement of the damping member 52 towards the side wall of the limiting slot 60. When the movement of the damping member 52 towards the side wall of the limiting slot 60 is limited, the bending deformation of the damping member 52 towards the side wall of the limiting slot 60 is small, which can improve the bending deformation of the damper 50 in the slot width direction of the limiting slot 60.

[0180] Since the first limiting portion 521 is a protruding structure on the side wall of the damping member 52 facing the limiting slot 60, by arranging the first limiting portion 521, some embodiments of the present application can avoid the bending deformation of the damper 50 towards the side wall of the limiting slot 60, so as to avoid the problems of unstable damping force, noise, shortened service life and the like of the damper 50, so as to enhance the stability of the realization of the slow descending function of the door cover 40, and at the same time, can improve the service life of the damper 50 and reduce the noise generated by the damper 50.

[0181] On the basis that the slot width of the limiting slot 60 is unchanged, by increasing the size of the damping member 52 in the slot width direction, the gap between the damping member 52 and the side wall of the limiting slot 60 can also be reduced, and the movement of the damping member 52 towards the side wall of the limiting slot 60 is limited. However, in this way, when the damping member 52 moves in the limiting slot 60 towards the damper body, if the damping member 52 deviates towards the side wall of the limiting slot 60, the entire surface of the damping member 52 facing the side wall of the limiting slot 60 will be in contact with the side wall of the limiting slot 60, so that the area of contact and friction between the damping member 52 and the side wall of the limiting slot 60 is larger, and the damping member 52 is more likely to be stuck on the slot wall of the limiting slot 60, which is not conducive to the smooth movement of the damping member 52 in the limiting slot 60 towards the damper body, and the door cover 40 will have a sense of stagnation during rotation. Moreover, due to the influence of the machining tolerance, the gap between the damping member 52 and the side wall of the limiting slot 60 will be large or small. If the damping member 52 moves towards the damper body and is also pushed by the door cover 40 to move towards the side wall of the limiting slot 60, the damping member 52 will be in contact with and stuck on the slot wall of the limiting slot 60 in the area where the gap between the damping member 52 and the side wall of the limiting slot 60 is increased, which will affect the movement of the damping member 52 towards the damper body.

[0182] Compared with the way of increasing the size of the damping member 52 in the slot width direction, some embodiments of the present application only need to reduce the gap between the damping member 52 at the position of the first limiting part 521 and the side wall of the limiting slot 60, and the movement of the damping member 52 towards the side wall of the limiting slot 60 can be limited by the setting of the first limiting part 521. Moreover, since the first limiting part 521 is a local protrusion on the damping member 52, the gap between the first limiting part 521 and the side wall of the limiting slot 60 is easier to control, and the movement of the damping member 52 towards the side wall of the limiting slot 60 can be better limited.

[0183] The minimum gap between the first limiting part 521 and the side wall of the limiting slot 60 is D1. Wherein, D1 < 0.25mm. For example, D1 can be 0.24mm, 0.23mm, 0.20mm, 0.16mm, 0.13mm, etc.

[0184] If D1 ≥ 0.25mm, although the first limiting part 521 is provided, when the damping member 52 moves towards or away from the damper body, the damping member 52 will still be pushed by the door cover 40 or the damping medium to move towards the side wall of the limiting slot 60 and be bent and deformed.

[0185] Therefore, some embodiments of the present application can make D1 as small as possible when D1 < 0.25 mm on the basis of ensuring smooth movement of the damping member 52 towards or away from the damper body, so as to prevent the damping member 52 from being deformed by bending when moving towards the side wall of the limiting groove 60 under the pushing of the door cover 40 or the damping medium, enhance the stability of the damping force, the service life of the damper 50, and reduce the noise generated by the damping member 52.

[0186] It should be noted that along the groove width direction of the limiting groove 60, the first limiting part 521 has a point closest to the side wall of the limiting groove 60 on the side facing the side wall of the limiting groove 60. The gap between this point and the side wall of the limiting groove 60 can be regarded as the minimum gap D1. Therefore, measuring the gap between this point and the side wall of the limiting groove 60 in the groove width direction of the limiting groove 60 is the minimum gap D1.

[0187] In some embodiments, the first limiting part 521 can be a rectangular block. At this time, the side of the first limiting part 521 facing the side wall of the limiting groove 60 can be a plane, and the end of the first limiting part 521 towards the damper body will be a right-angle structure.

[0188] If the first limiting part 521 is a rectangular block, the end of the first limiting part 521 towards the damper body has a clear edge. In this way, when the damping member 52 moves towards the side wall of the limiting groove 60 under the pushing of the door cover 40, the edge of the first limiting part 521 is easy to be stuck on the side wall of the limiting groove 60, affecting the movement of the damping member 52 towards the damper body.

[0189] Figure 10 An enlarged view is shown at B. Figure 8 An enlarged view is shown at B.

[0190] To this end, referring to Figure 9 and Figure 10 shown, in other embodiments, the end of the first limiting part 521 towards the damper body can have a first guide structure 5211. The side of the first guide structure 5211 facing the side wall of the limiting groove 60 has a first guide surface 5212. Along the direction of the damping member 52 towards the damper body, the gap between the first guide surface 5212 and the side wall of the limiting groove 60 increases. For example, along the direction of the damping member 52 towards the damper body, the gap between the first guide surface 5212 and the side wall of the limiting groove 60 can gradually increase.

[0191] By providing the first guide structure 5211, the shape of the side of the first limiting part 521 facing the side wall of the limiting groove 60 can be changed, so that the first limiting part 521 has a larger gap between the first guide surface 5212 and the side wall of the limiting groove 60, so as to reduce the contact area between the first limiting part 521 and the side wall of the limiting groove 60 when the first limiting part 521 moves towards the side wall of the limiting groove 60.

[0192] When the damping member 52 moves toward the side wall of the limiting groove 60 under the push of the door cover 40, the remaining positions of the first limiting portion 521 facing the side wall of the limiting groove 60 will preferentially contact the side wall of the limiting groove 60. This restricts the movement of the damping member 52 toward the side wall of the limiting groove 60 when it moves toward the damper body, thereby improving the bending deformation of the damper 50 in the groove width direction of the limiting groove 60 when it is pushed toward the damper body. The remaining positions of the first limiting portion 521 facing the side wall of the limiting groove 60 include the positions of the first limiting portion 521 that are not on the first guide surface 5212.

[0193] Furthermore, since the first limiting part 521 has a large gap between the first guide surface 5212 and the side wall of the limiting groove 60, when the first limiting part 521 contacts the side wall of the limiting groove 60 in other positions, the first guide surface 5212 will also guide the first limiting part 521 to move in a direction away from the side wall of the limiting groove 60, so as to avoid the first limiting part 521 getting stuck in the side wall of the limiting groove 60 and ensure that the damping member 52 moves smoothly toward the damper body when pushed by the door cover 40.

[0194] See Figure 9 and Figure 10 As shown, in some embodiments, the first guide surface 5212 can be an arc-shaped surface, so that the gap between the first guide surface 5212 and the side wall of the limiting groove 60 is increased in the direction along the damper 52 toward the damper body. At the same time, since the first guide surface 5212 is an arc-shaped surface, it is also possible to achieve an arc-shaped connection between the first guide surface 5212 and the remaining positions of the side wall of the first limiting part 521 facing the limiting groove 60, so as to avoid the first limiting part 521 having sharp edges on the side wall facing the limiting groove 60, which would affect the movement of the damper 52 toward the damper body.

[0195] In some embodiments, the first guide surface 5212 can also be an inclined surface, which can also increase the gap between the first guide surface 5212 and the side wall of the limiting groove 60 in the direction of the damper 52 toward the damper body. When the inclined surface is arc-shaped to the remaining position of the side wall of the first limiting part 521 facing the limiting groove 60, it can also prevent the first limiting part 521 from having sharp edges on the side wall facing the limiting groove 60, which would affect the movement of the damper 52 toward the damper body.

[0196] It should be noted that when the door cover 40 rotates relative to the cabinet 10 to open the drop opening 121, the abutting portion 41 of the door cover 40 will be separated from the damping member 52. At this time, the damping member 52 will move away from the damper body under the pushing of the damping medium to reset the damping member 52 to provide damping force for the next time the door cover 40 rotates relative to the cabinet 10 to close the drop opening 121. Similarly, when the damping member 52 moves away from the damper body under the pushing of the damping medium, it is also possible to move towards the side wall of the limiting groove 60, causing the damping member 52 to be bent and deformed.

[0197] To this end, as shown in FIGS. Figure 9 and Figure 10 In some embodiments, when the first limiting portion 521 has the first guide structure 5211, the first limiting portion 521 can also be provided with a second guide structure 5213 at one end away from the damper body. The second guide structure 5213 has a second guide surface 5214 facing one side of the side wall of the limiting groove 60, and the gap between the second guide surface 5214 and the side wall of the limiting groove 60 increases in the direction from the damper body to the damping member 52. For example, the gap between the second guide surface 5214 and the side wall of the limiting groove 60 can also gradually increase in the direction from the damper body to the damping member 52.

[0198] By providing the second guide structure 5213, the shape of the first limiting portion 521 on the side facing the side wall of the limiting groove 60 can be further changed, so that the first limiting portion 521 also has a larger gap between the second guide surface 5214 and the side wall of the limiting groove 60, to reduce the contact area between the second limiting portion 522 and the side wall of the limiting groove 60 when the first limiting portion 521 moves towards the side wall of the limiting groove 60.

[0199] In this way, when the damping member 52 moves away from the damper body under the pushing of the damping medium and moves towards the side wall of the limiting groove 60, the remaining positions of the first limiting portion 521 facing the side wall of the limiting groove 60 will preferentially contact the side wall of the limiting groove 60 to limit the movement of the damping member 52 in the direction towards the side wall of the limiting groove 60 when it moves away from the damper body, thereby improving the bending deformation of the damper 50 in the groove width direction of the limiting groove 60 when it is pushed to move away from the damper body.

[0200] Similarly, since the first limiting portion 521 has a larger gap between the second guide surface 5214 and the side wall of the limiting groove 60, when the first limiting portion 521 contacts the side wall of the limiting groove 60 at the remaining positions, the second guide surface 5214 will also guide the first limiting portion 521 to move away from the side wall of the limiting groove 60 to avoid the first limiting portion 521 being stuck in the side wall of the limiting groove 60, ensuring smooth movement of the damping member 52 away from the damper body when it is pushed.

[0201] In some embodiments, the second guide surface 5214 may also be an arc-shaped surface or an inclined surface to ensure that the gap between the second guide surface 5214 and the side wall of the limiting groove 60 is increased along the direction from the damper body to the damping member 52. For details, please refer to the relevant description of the first guide surface 5212 above, which will not be repeated here.

[0202] In some embodiments, the second guide structure 5213 and the first guide structure 5211 can be symmetrical structures on the first limiting portion 521 to simplify the structure of the first limiting portion 521 and the damper 50.

[0203] Since the first guide structure 5211 and the second guide structure 5213 are provided at both ends of the first limiting part 521, the minimum gap D1 between the first limiting part 521 and the side wall of the limiting groove 60 can be increased at both ends of the first limiting part 521 and the side wall of the limiting groove 60 without affecting the minimum gap D1 between the first limiting part 521 and the side wall of the limiting groove 60, so as to ensure the smooth movement of the damping member 52 away from or towards the damper body. At this time, the middle part 5215 has a point closest to the side wall of the limiting groove 60 it faces. Along the groove width direction of the limiting groove 60, the gap between this point on the middle part 5215 and the side wall of the limiting groove 60 can be regarded as the minimum gap D1.

[0204] See Figure 9 and Figure 10 As shown, in some embodiments, the sidewalls of the limiting groove 60 may include a first sidewall 61 and a second sidewall 62 disposed opposite to each other in the groove width direction. The top of the chassis 10 may define the first sidewall 61. The mounting member 30 may define a portion of the second sidewall 62. The damping member 52 has a first limiting portion 521 on each of the two sidewalls opposite to the first sidewall 61 and the second sidewall 62.

[0205] When the damping member 52 moves toward the first sidewall 61 under the push of the door cover 40, the first limiting part 521 can restrict the movement of the damping member 52 toward the first sidewall 61, thereby improving the bending deformation of the damping member 52 in the direction toward the first sidewall 61. When the damping member 52 moves toward the second sidewall 62 under the push of the door cover 40, the first limiting part 521 can restrict the movement of the damping member 52 toward the second sidewall 62, thereby improving the bending deformation of the damping member 52 in the direction toward the second sidewall 62.

[0206] Therefore, by setting the first limiting part 521 on the two side walls opposite to the first side wall 61 and the second side wall 62, the damping member 52 can be prevented from bending and deforming when it moves toward any side wall of the limiting groove 60 in the groove width direction under the push of the door cover 40 or the damping medium, so that the damping member 52 has a better anti-bending deformation effect in the groove width direction of the limiting groove 60 when it is pushed.

[0207] Referring to Figure 9 and Figure 10 In some embodiments, as shown in Figs. 52 and 53, at least two first limiting portions 521 can be arranged on the same side wall of the damping member 52 in the direction of the damping member 52 towards the damper body. Figure 8 and Figure 9 In Figs. 52 and 53, two first limiting portions 521 are shown on the same side wall of the damping member 52, which does not constitute a limitation on the number of first limiting portions 521. For example, in some embodiments, if there is enough space on the damping member 52, three first limiting portions 521 or the like can also be arranged on the same side wall of the damping member 52.

[0208] It should be noted that in some embodiments, one first limiting portion 521 can also be arranged on the same side wall of the damping member 52.

[0209] Compared with the case where one first limiting portion 521 is arranged on the same side wall of the damping member 52, by arranging at least two first limiting portions 521, when the damping member 52 moves towards or away from the damper body, the first limiting portion 521 can limit the movement of the damping member 52 towards the side wall of the limiting groove 60 at different positions, thereby enhancing the limiting effect of the first limiting portion 521 on the movement of the damping member 52.

[0210] The improvements of the damping member 52 and the mounting member 30 will be further described below in combination with the accompanying drawings and some embodiments.

[0211] Figure 11 A sectional view of the damper 50 in the C-C direction of the case 10 is shown in Figs. 54 and 55. Figure 5 A sectional view of the damper 50 in the C-C direction of the case 10 is shown in Figs. 54 and 55. Figure 12 A sectional view of the damper 50 in the C-C direction of the case 10 is shown in Figs. 54 and 55. Figure 11 An enlarged view at D is shown in Figs. 56 and 57.

[0212] Referring to Figure 11 and Figure 12 In some embodiments, as shown in Figs. 52 and 53, the mounting member 30 can further include a shielding portion 33. The shielding portion 33 shields the slot of the limiting groove 60. In this way, when the damping member 52 moves to the position where the shielding portion 33 is located in the limiting groove 60, the shielding portion 33 will shield the top of the damping member 52.

[0213] Figure 13 An enlarged view at D is shown in Figs. 56 and 57. Figure 12 An enlarged view at D is shown in Figs. 56 and 57.

[0214] Referring to Figure 13As shown, the damping member 52 is configured to have an overlapping region with the shielding portion 33 in the height direction of the cabinet 10 when not being pushed by the door cover 40. The height direction of the cabinet 10 is parallel to the Z direction. The position of the damping member 52 in the limiting groove 60 when not being pushed by the door cover 40 can be regarded as an initial position. The position of the damping member 52 in the limiting groove 60 before the door cover 40 is rotated to the preset angle mentioned above from the side of the discharge port 121 can also be regarded as an initial position.

[0215] If the damping member 52 does not overlap with the shielding portion 33 when not being pushed by the door cover 40, when the damping member 52 is pushed by the door cover 40 to move to the side of the shielding portion 33 before moving to the damping member body and the damping member 52 is bent and deformed when moving to the side of the shielding portion 33, the damping member 52 is easily clamped on the end surface of the shielding portion 33 on the side of the damping member 52, so that the damping member 52 cannot continue to move to the damping member body.

[0216] Due to the arrangement of the overlapping region, the part of the damping member 52 in the overlapping region can be blocked by the shielding portion 33 before moving to the damping member body, so as to limit the bending and deformation of the damping member 52 when moving to the side of the shielding portion 33 in the groove depth direction, so that the damping member 52 cannot be clamped on the end surface of the shielding portion 33 on the side of the damping member 52.

[0217] Therefore, by arranging the overlapping region, some embodiments of the present application can limit the movement of the damping member 52 to the side of the shielding portion 33, the bending and deformation of the damping member 52 to the side of the shielding portion 33 in the groove depth direction of the limiting groove 60 is small, the bending and deformation of the damper 50 to the side of the shielding portion 33 in the groove depth direction of the limiting groove 60 can be improved, so that the damping member 52 continues to move to the damping member body, so as to enhance the stability of the slow descending function of the door cover 40, and at the same time, the service life of the damper 50 can be further improved and the noise generated by the damper 50 can be reduced.

[0218] It should be noted that when the damping member 52 moves to the side of the shielding portion 33 and abuts against the shielding portion 33, the shielding portion 33 will exert a force on the damping member 52, which can make the damping member 52 move away from the shielding portion 33, thereby limiting the movement of the damping member 52 to the side of the shielding portion 33.

[0219] Specifically, when the shielding portion 33 is abutted by the damping member 52, the shielding portion 33 can be elastically deformed. Compared with the case where the shielding portion 33 does not elastically deform, the service life of the mounting member 30 can be prolonged when the shielding portion 33 elastically deforms.

[0220] Although the overlapping region is provided to prevent the damping member 52 from being stuck on the end face of the blocking portion 33 on the side of the damping member 52, when the damping member 52 moves toward the blocking portion 33 within the blocking range of the blocking portion 33, the damping member 52 can still be stuck on the blocking portion 33 if the damping member 52 moves toward the blocking portion 33 under the pushing of the door cover 40.

[0221] To this end, referring to Figure 13 As shown in FIG. 5, in some embodiments, the damping member 52 has a guide arc surface 523 at a position corresponding to the overlapping region. The blocking portion 33 has a guide inclined surface 331 facing the damping member 52, and at least a part of the guide inclined surface 331 is within the overlapping region. Moreover, the guide inclined surface 331 is configured to be capable of contacting at least a part of the guide arc surface 523 when the damping member 52 moves toward the blocking portion 33, so as to limit the movement of the damping member 52 toward the blocking portion 33, thereby limiting the movement of the damping member 52 toward the blocking portion 33, reducing the bending deformation of the damping member 52 toward the blocking portion 33 in the slot depth direction of the limiting slot 60, and improving the bending deformation of the damper 50 toward the blocking portion 33 in the slot depth direction of the limiting slot 60 when the damper 50 is pushed.

[0222] Moreover, due to the provision of the guide arc surface 523 and the guide inclined surface 331, when the guide inclined surface 331 contacts at least a part of the guide arc surface 523, the guide inclined surface 331 guides the damping member 52 to move away from the blocking portion 33, so as to enable the damping member 52 to continue to move toward the damper body.

[0223] In addition, due to the provision of the guide arc surface 523, the edge of the damping member 52 adjacent to the side of the blocking portion 33 can be rounded, so as to prevent the damping member 52 from being stuck on the blocking portion 33 when the damping member 52 continues to move toward the damper body beyond the guide inclined surface 331.

[0224] It should be noted that, in some embodiments, when the damping member 52 has the first limiting portion 521 and the damping member 52 has the overlapping region with the blocking portion 33 when the damping member 52 is not pushed by the door cover 40, the bending deformation of the damper 50 in the slot width direction of the limiting slot 60 can be improved, and the bending deformation of the damper 50 toward the blocking portion 33 in the slot depth direction of the limiting slot 60 can also be improved, so that the bending deformation of the damper 50 toward the blocking portion 33 in the slot width direction and the slot depth direction can be effectively controlled, to further enhance the stability of the slow descent function of the door cover 40, and at the same time, the service life of the damper 50 can be further improved, and the noise generated by the damper 50 can be reduced.

[0225] Referring to Figure 13As shown, in some embodiments, the size of the coincident region is D2 along the damping member 52 towards the damper body, and D2>1mm. For example, the size of the coincident region can be 1.5mm, 1.8mm, 2mm, etc.

[0226] When D2≤1mm, D2 is small, the limiting effect of the blocking portion 33 on the movement of the damping member 52 towards the blocking portion 33 side is limited, and the control strength of the bending deformation of the damper 50 in the groove depth direction towards the blocking portion 33 side is also limited.

[0227] In contrast, in the present application, when D2>1mm, D2 is large, the limiting effect of the blocking portion 33 on the movement of the damping member 52 towards the blocking portion 33 side is also enhanced, and the control strength of the bending deformation of the damper 50 in the groove depth direction towards the blocking portion 33 side is also improved synchronously.

[0228] Figure 14 As shown Figure 13 The angle diagram of the guide inclined surface 331 is shown.

[0229] Referring to Figure 14 As shown, in addition to D2, in some embodiments, the included angle between the guide inclined surface 331 and the side of the blocking portion 33 away from the slot is α, and α<45°. For example, α can be 44°, 43°, 35°, 30°, 25°, etc.

[0230] Since α affects the slope of the guide inclined surface 331, when α gradually approaches 90° or 0°, the guide inclined surface 331 will disappear, therefore, 0°<α<90°.

[0231] When α is greater than 45°, the slope of the guide inclined surface 331 is large, the steeper the guide inclined surface 331, the limited guiding effect on the damping member 52, and the smoothness of the guiding arc surface 523 of the damping member 52 moving on the guide inclined surface 331 is not good.

[0232] In contrast, in the present application, when α is less than 45°, the slope of the guide inclined surface 331 is small, the gentler the guide inclined surface 331, the better the guiding effect on the damping member 52, and the guiding arc surface 523 of the damping member 52 moving on the guide inclined surface 331 has good smoothness.

[0233] In some embodiments, 20°<α<45°.

[0234] However, smaller α is not always better. For example, when α is less than 20°, the guide slope 331 will be too gentle. Only when the guide arc surface 523 of the damping member 52 moves a long distance on the guide slope 331 will the guide slope 331 have a limiting effect on the movement of the damping member 52 toward the blocking part 33. At the same time, if the guide slope 331 is too gentle, it will also cause the blocking part 33 to have a long thin wall at the position of the guide slope 331, which will affect the strength of the blocking part 33.

[0235] In contrast, this application ensures that when 20° < α < 45°, the guide arc surface 523 of the damping member 52 moves smoothly on the guide slope 331, which can improve the limiting efficiency of the guide slope 331 on the damping member 52, while also ensuring the strength of the shielding part 33.

[0236] Figure 15 for Figure 12 A partial schematic diagram of the damping component and the limiting groove.

[0237] See Figure 15 As shown, the damping member 52 and the blocking part 33 have a minimum gap of D3. The minimum gap D3 is located at the position of the damping member 52 and the blocking part 33 on the non-guide slope 331. D3 < 0.3 mm. For example, D3 can be 0.25 mm, 0.20 mm, 0.15 mm, 0.1 mm, etc.

[0238] If D3 ≥ 0.3 mm, the gap (i.e. D3) between the damping member 52 and the shielding part 33 at the non-guide slope 331 position will be too large. This will still cause the damping member 52 to move toward or away from the damper body and bend and deform under the push of the door cover 40 or the damping medium.

[0239] Therefore, in some embodiments of this application, when D3 < 0.3 mm, D3 can be set as small as possible while ensuring that the damping member 52 moves smoothly toward or away from the damper body. This is to prevent the damping member 52 from bending and deforming when it moves toward the shielding part 33 under the push of the door cover 40 or the damping medium, thereby enhancing the stability of the damping force, the service life of the damper 50, and reducing the noise generated by the damping member 52.

[0240] Figure 16 It shows Figure 12 A schematic diagram of the structure of the middle damping component 52 and the bottom wall 63 of the limiting groove 60. Figure 17 A partial schematic diagram of a damper 50 is shown from a second perspective.

[0241] See Figure 16 and Figure 17As shown, in some embodiments, the damping member 52 has a second limiting portion 522 protruding towards one side of the bottom wall 63, and the second limiting portion 522 has a gap with the bottom wall 63 of the limiting slot 60. The second limiting portion 522 is used to limit the movement of the damping member 52 towards the bottom wall 63.

[0242] On the basis of the unchanged slot depth of the limiting slot 60, by the arrangement of the second limiting portion 522, the gap between the second limiting portion 522 and the bottom wall 63 of the damping member 52 can be reduced. In this way, during the movement of the damping member 52 towards the damper body, if the damping member 52 is still moved towards the bottom wall 63 under the pushing of the door cover 40, the second limiting portion 522 will be in contact with the side wall of the limiting slot 60 in priority to the rest of the damping member 52, so as to limit the movement of the damping member 52 towards the bottom wall 63. When the movement of the damping member 52 towards the bottom wall 63 is limited, the bending deformation of the damping member 52 towards the bottom wall 63 is smaller, and the bending deformation of the damper 50 in the slot depth direction towards the bottom wall 63 when the damper 50 is pushed can be improved.

[0243] Since the second limiting portion 522 is a protruding structure on the damping member 52, by the arrangement of the second limiting portion 522, some embodiments of the present application can avoid the bending deformation of the damper 50 in the slot depth direction towards the bottom wall 63, so as to avoid the problems of unstable damping force, noise, shortened service life and the like of the damper 50, so as to enhance the stability of the realization of the slow descending function of the door cover 40, and at the same time, the service life of the damper 50 can be improved and the noise generated by the damper 50 can be reduced.

[0244] Similarly, compared with the way of increasing the size of the damping member 52 in the slot depth direction, by the arrangement of the first limiting portion 521, some embodiments of the present application can limit the movement of the damping member 52 towards the bottom wall 63 only by reducing the gap between the second limiting portion 522 and the bottom wall 63 of the damping member 52. And since the second limiting portion 522 is a local protrusion on the damping member 52, the gap between the second limiting portion 522 and the bottom wall 63 is easier to control, and the damping member 52 can be better limited from moving towards the bottom wall 63. For specific reasons, please refer to the related description of the first limiting portion 521, which will not be repeated here.

[0245] It should be noted that, in some embodiments, when the damping member 52 has the first limiting portion 521 and the second limiting portion 522, the bending deformation of the damper 50 in the slot width direction of the limiting slot 60 can be improved, and at the same time, the bending deformation of the damper 50 in the slot depth direction towards the bottom wall 63 of the limiting slot 60 can also be improved, so that the bending deformation of the damper 50 in the slot width direction and the slot depth direction towards the bottom wall 63 side can be effectively controlled, so as to further enhance the stability of the realization of the slow descending function of the door cover 40, and at the same time, the service life of the damper 50 can be further improved and the noise generated by the damper 50 can be reduced.

[0246] It should be noted that in some embodiments, when the damping member 52 has the first limiting portion 521 and the second limiting portion 522, and the damping member 52 has an overlapping area with the shielding portion 33 when the damping member 52 is not pushed by the door cover 40, the bending deformation of the damper 50 in the slot width direction of the limiting slot 60 can be improved, and the bending deformation of the damper 50 in the slot depth direction of the limiting slot 60 towards the shielding portion 33 and the bottom wall 63 can also be improved. The bending deformation of the damper 50 in the slot width direction and the slot depth direction can be effectively controlled to further enhance the stability of the slow-falling function of the door cover 40, and at the same time, the service life of the damper 50 can be further improved, and the noise generated by the damper 50 can be reduced.

[0247] The minimum gap between the second limiting portion 522 and the bottom wall 63 is D4, and D4 < 0.3 mm. For example, D4 can be 0.25 mm, 0.23 mm, 0.20 mm, 0.15 mm, 0.10 mm, etc.

[0248] If D4 ≥ 0.3 mm, although the second limiting portion 522 is provided, the damping member 52 will still move towards the bottom wall 63 under the pushing of the door cover 40 or the damping medium and be bent and deformed when moving towards or away from the damper body.

[0249] Therefore, in some embodiments of the present application, when D4 < 0.3 mm, on the basis of ensuring smooth movement of the damping member 52 towards or away from the damper body, D4 can be set as small as possible to prevent the damping member 52 from moving towards the bottom wall 63 under the pushing of the door cover 40 or the damping medium and being bent and deformed, thereby enhancing the stability of the damping force, the service life of the damper 50, and reducing the noise generated by the damping member 52.

[0250] It should be noted that along the slot depth direction of the limiting slot 60, the second limiting portion 522 has a point closest to the bottom wall 63 on the side facing the bottom wall 63. The gap between this point and the bottom wall 63 can be regarded as the minimum gap D4. Therefore, measuring the gap between this point and the bottom wall 63 in the slot depth direction of the limiting slot 60 is the minimum gap D4.

[0251] Like the first limiting portion 521, the second limiting portion 522 can also be a rectangular block. At this time, the end of the second limiting portion 522 facing the damper body will be a right-angle structure.

[0252] Similarly, when the second limiting portion 522 is a rectangular block, the second limiting portion 522 has obvious edges. When the damping member 52 moves towards the bottom wall 63 under the pushing of the door cover 40, the edges of the second limiting portion 522 are easy to be stuck on the bottom wall 63, which affects the movement of the damping member 52 towards or away from the damper body.

[0253] To this end, referring to Figure 16 and Figure 17 In some embodiments, the second limiting portion 522 has a third guiding structure 5221 at the end thereof facing the damper body, and the third guiding structure 5221 has a third guiding surface 5222 facing one side of the bottom wall 63 of the limiting slot 60. Wherein, the gap between the third guiding surface 5222 and the bottom wall 63 increases in the direction of the damper body along the damper element 52, similar to the first guiding surface 5212.

[0254] By providing the third guiding structure 5221, the shape of the second limiting portion 522 on the side thereof facing the bottom wall 63 can be changed, so that the second limiting portion 522 has a larger gap between the third guiding surface 5222 and the bottom wall 63, to reduce the contact area between the second limiting portion 522 and the bottom wall 63 when the second limiting portion 522 moves towards the bottom wall 63.

[0255] In this way, when the damper element 52 moves towards the bottom wall 63 under the push of the door cover 40, the remaining positions of the second limiting portion 522 facing the bottom wall 63 will preferentially contact the bottom wall 63, to limit the movement of the damper element 52 in the direction towards the bottom wall 63 when moving towards the damper body, thereby improving the bending deformation of the damper 50 in the direction towards the bottom wall 63 when moving towards the damper body. Wherein, the remaining positions of the second limiting portion 522 facing the bottom wall 63 include the positions of the second limiting portion 522 other than the third guiding surface 5222.

[0256] Similarly, since the second limiting portion 522 has a larger gap between the third guiding surface 5222 and the bottom wall 63, when the second limiting portion 522 contacts the bottom wall 63 at the remaining positions, the third guiding surface 5222 will also guide the second limiting portion 522 to move in the direction away from the bottom wall 63, to avoid the second limiting portion 522 being stuck on the bottom wall 63, and to ensure smooth movement of the damper element 52 towards the damper body.

[0257] In some embodiments, the second guiding surface 5214 can be an arc surface, so that the gap between the third guiding surface 5222 and the bottom wall 63 increases in the direction of the damper body along the damper element 52, to avoid the first limiting portion 521 having an edge on the side wall facing the limiting slot 60, which affects the movement of the damper element 52 towards the damper body.

[0258] Alternatively, the second guide surface 5214 can also be an inclined surface, which can also increase the gap between the third guide surface 5222 and the bottom wall 63 in the direction of the damping member 52 towards the damper body. When the inclined surface is arc-shapedly connected with the remaining position of the second limiting portion 522 facing the bottom wall 63, the second limiting portion 522 can also avoid the occurrence of an edge facing the bottom wall 63, which can affect the movement of the damping member 52 towards the damper body.

[0259] The second limiting portion 522 has a fourth guide structure 5223 at the end away from the damper body, and the side facing the bottom wall 63 of the fourth guide structure 5223 has a fourth guide surface 5224.

[0260] Referring to Figure 15 and Figure 16 In some embodiments, when the second limiting portion 522 has the third guide structure 5221, the second limiting portion 522 can also be provided with a fourth guide structure 5223 at the end away from the damper body. The side facing the bottom wall 63 of the fourth guide structure 5223 has a fourth guide surface 5224. Among them, the fourth guide surface 5224, like the second guide surface 5214, has a gradually increasing gap between the fourth guide surface 5224 and the bottom wall 63 in the direction of the damper body to the damping member 52. For example, the gap between the fourth guide surface 5224 and the bottom wall 63 can also gradually increase in the direction of the damper body to the damping member 52.

[0261] Through the arrangement of the fourth guide structure 5223, the shape of the side of the first limiting portion 521 facing the side wall of the limiting groove 60 can be further changed, so that the second limiting portion 522 has a larger gap between the fourth guide surface 5224 and the bottom wall 63, so as to reduce the contact area between the second limiting portion 522 and the bottom wall 63 when the second limiting portion 522 moves towards the bottom wall 63.

[0262] In this way, when the damping member 52 is pushed by the damping medium to move away from the damper body and moves towards the bottom wall 63, the remaining position of the second limiting portion 522 facing the bottom wall 63 will preferentially contact the bottom wall 63 to limit the movement of the damping member 52 in the direction towards the bottom wall 63 when moving away from the damper body, thereby improving the bending deformation of the damper 50 in the direction towards the bottom wall 63 when moving away from the damper body.

[0263] At the same time, the fourth guide surface 5224 also guides the second limiting portion 522 to move away from the bottom wall 63, so as to avoid the second limiting portion 522 being stuck in the bottom wall 63, and ensure the smooth movement of the damping member 52 away from the damper body.

[0264] In some embodiments, the fourth guide surface 5224 has the same structure as the third guide surface 5222, and the relevant description of the third guide surface 5222 is referred to above, which will not be repeated here. For example, in some embodiments, the third guide structure 5221 and the fourth guide structure 5223 can be symmetrical structures on the second limiting portion 522, so as to simplify the structure of the second limiting portion 522 and the damper 50.

[0265] It should be noted that, since the third guide structure 5221 and the fourth guide structure 5223 are arranged at the two ends of the second limiting portion 522, the gap between the second limiting portion 522 and the bottom wall 63 at the two ends can be increased without affecting the minimum gap D4 between the second limiting portion 522 and the bottom wall 63, so as to ensure the smooth movement of the damping member 52 away from or close to the damper body. At this time, the second limiting portion 522 has a point closest to the bottom wall 63 on the portion between the third guide structure 5221 and the fourth guide structure 5223. In the direction of the groove depth of the limiting groove 60, the gap between the point on the second limiting portion 522 and the bottom wall 63 can be regarded as the minimum gap D4.

[0266] Referring to Figure 17 In some embodiments, as shown in the figure, when the shielding portion 33 shields the slot opening of the limiting groove 60, the minimum gaps between the damping member 52 and the shielding portion 33, and between the damping member 52 and the bottom wall 63 of the limiting groove 60 can be less than 0.3 mm. That is, the minimum gaps D3 and D4 can be less than 0.3 mm.

[0267] By limiting the minimum gaps between the damping member 52 and the shielding portion 33, and between the damping member 52 and the bottom wall 63 of the limiting groove 60, the movement of the damping member 52 in the direction of the bottom wall 63 of the limiting groove 60 and in the direction of the shielding portion 33 can also be limited, so as to improve the bending deformation of the damper 50 in the direction of the groove depth of the limiting groove 60, further enhance the stability of the realization of the slow drop function of the door cover 40, and further improve the service life of the damper 50 and reduce the noise generated by the damper 50.

[0268] In combination with Figure 18 to Figure 20 In some embodiments, the impeller washing machine further comprises a control panel 70. The control panel 70 can comprise a surrounding portion and a device mounting portion 73. The surrounding portion can comprise a front surrounding portion 71 and a rear surrounding portion 72. The front surrounding portion 71 can be connected to one end of the device mounting portion 73 close to the front side of the cabinet 10. The rear surrounding portion 72 can be connected to one end of the device mounting portion 73 close to the rear side of the cabinet 10. The front surrounding portion 71, the device mounting portion 73 and the rear surrounding portion 72 jointly surround a mounting space. The mounting space can be used to accommodate and mount the components of the impeller washing machine. The front surrounding portion 71 and the rear surrounding portion 72 shield and protect the mounting space from the front and rear sides of the impeller washing machine, preventing the internal components from being directly contacted with the outside.

[0269] The device mounting portion 73 can be arranged on the top of the surrounding frame 12. The device mounting portion 73 can provide mounting positions for the components of the pulsator washing machine, so that the operation part of the washing machine is located above the surrounding frame 12, which can adapt to the height of the user, and facilitate the user to operate outside the device mounting portion 73 to select the function of the washing machine.

[0270] The front surrounding portion 71, the device mounting portion 73 and the rear surrounding portion 72 can be integrally formed, which can be processed by injection molding or other processes, which can reduce the installation difficulty and improve the assembly efficiency. Alternatively, the front surrounding portion 71, the device mounting portion 73 and the rear surrounding portion 72 can also be a split structure, and the adjacent two parts can be fixedly connected by screws, buckles or other forms to reduce the processing difficulty.

[0271] In some embodiments, the control panel 70 includes a circuit board 91. The circuit board 91 can receive inputs from the user interface, such as the knob 80 or the button, and convert these inputs into specific operation instructions to control the various functional components of the pulsator washing machine, such as the motor, the pump, the valve and the like.

[0272] The circuit board 91 is arranged on the side of the device mounting portion 73 facing the surrounding frame 12. The circuit board 91 is located inside the mounting space. The device mounting portion 73 can provide protection for the circuit board 91 to prevent the circuit board 91 from being directly contacted with the external environment.

[0273] The circuit board 91 is connected with an encoder. The encoder is used to detect and control the rotation position, speed and direction of the knob 80. The encoder has a rotatable encoder control rod 911. The encoder control rod 911 is used to connect with the knob 80, and the user can control the rotation of the encoder control rod 911 by rotating the knob 80 to select and switch the working mode of the pulsator washing machine.

[0274] The control panel 70 can include a knob 80. The knob 80 is connected with the encoder control rod 911. By rotating the knob 80, the encoder control rod 911 can be rotated relative to the circuit board 91 to select and switch the working mode of the pulsator washing machine.

[0275] In some embodiments, the control panel 70 can include a knob support 94. The knob support 94 is arranged on the side of the circuit board 91 facing the device mounting portion 73. The knob support 94 can provide a mounting space for the knob 80 to ensure that the knob 80 remains stable during operation. The knob 80 is movably arranged in the knob support 94. The knob 80 drives the encoder control rod 911 to rotate relative to the knob support 94.

[0276] The device mounting portion 73 is provided with a mounting opening 731. When the knob 80 is connected with the knob support 94, part of the knob 80 can extend to the outside of the device mounting portion 73 through the mounting opening 731, so as to facilitate the user to operate.

[0277] It can be understood that there is a gap between the knob 80 and the mounting opening 731 of the device mounting portion 73, which can communicate the inside and the outside of the enclosure. Water can easily enter the inside of the enclosure from the gap. Once the water contacts the circuit board 91 and the important components such as the encoder thereon, it may cause serious problems such as dampness and short circuit, thereby seriously interfering with the normal operation of the impeller washing machine.

[0278] The knob support 94 is provided with a flow guide structure 93. At least part of the flow guide structure 93 is directed towards the mounting opening 731. Then the water entering the inside of the enclosure through the mounting opening 731 will enter the flow guide structure 93. The flow guide structure 93 is annularly arranged on the periphery of the encoder control rod 911. Then the flow guide structure 93 can limit the water from contacting the encoder, thereby achieving the waterproof effect of the encoder.

[0279] The flow guide structure 93 has a flow guide outlet 933. The flow guide outlet 933 can facilitate the water in the flow guide structure 93 to be discharged, thereby avoiding the accumulation of water in the flow guide structure 93, and has a water drainage effect. The flow guide outlet 933 is in communication with the washing cavity 20. Then the water in the flow guide structure 93 will be discharged to the washing cavity 20 through the flow guide outlet 933, thereby avoiding the water from flowing onto the circuit board 91 or other components, and achieving the waterproof effect of the circuit board 91 and other components. In addition, the water is discharged into the washing cavity 20, which can also prevent the water from flowing to the ground, thereby reducing the risk of electric shock and improving the safety.

[0280] The device mounting portion 73 can be inclined towards the front side of the cabinet 10. On the one hand, the inclined device mounting portion 73 can facilitate the user to operate, and on the other hand, the inclined device mounting portion 73 can guide the water on the surface thereof, so that the surface of the device mounting portion 73 will not accumulate water. In addition, the knob support 94 is arranged on the device mounting portion 73, so that the knob support 94 is also in an inclined state, and the flow guide structure 93 thereon is also in an inclined state. The flow guide outlet 933 is located at the bottom of the flow guide structure 93, so that the water collected in the flow guide structure 93 can flow to the flow guide outlet 933 by gravity, thereby facilitating the discharge of water.

[0281] In combination Figure 24 As shown in FIG. 8, in some possible embodiments, the flow guide structure 93 can include a first flow guide channel 931. The first flow guide channel 931 is annularly arranged on the periphery of the encoder control rod 911. By arranging the first flow guide channel 931 on the periphery of the encoder control rod 911, the water will directly drop into the first flow guide channel 931, and will not directly contact the encoder control rod 911 by crossing the side wall of the first flow guide channel 931, thereby improving the waterproof effect.

[0282] The flow guiding structure 93 may include a second flow guiding channel 932. A first end of the second flow guiding channel 932 is connected to the bottom of the first flow guiding channel 931, and a second end of the second flow guiding channel has a flow guiding outlet 933. The second flow guiding channel 932 provides a clear drainage path, guiding water from the bottom of the first flow guiding channel 931 to the flow guiding outlet 933, ensuring that water can be smoothly discharged into the washing chamber 20 and preventing water accumulation.

[0283] The second flow channel 932 can be straight to discharge water in the shortest path, avoid water staying in the flow structure 93 for a long time, prevent moisture from damaging the circuit board 91 and encoder control rod 911, and reduce the risk of short circuit and moisture.

[0284] Combination Figure 27 and Figure 28 As shown, in some possible embodiments, the frame 12 may be provided with a liquid collection tank 124, which is connected to the flow guiding structure 93. By providing a liquid collection tank 124 on the frame 12, water discharged from the flow guiding outlet 933 of the flow guiding structure 93 can be collected in the liquid collection tank 124, reducing the possibility of water contacting other components.

[0285] The collection tank 124 may have a liquid outlet 125. The design of the liquid outlet 125 allows water in the collection tank 124 to be effectively drained. The liquid outlet 125 is connected to the washing chamber 20, and water can be directly introduced into the washing chamber 20 to merge with the water flow during the washing process.

[0286] Combination Figure 28 As shown, in some possible embodiments, the pulsator washing machine may also include a water tank 100. The water tank 100, as an intermediate storage and regulating device, is connected to the water inlet of the pulsator washing machine, capable of receiving and storing incoming water, and releasing water when needed, helping to better control the use and distribution of water during the washing process.

[0287] The water tank 100 is connected to the liquid outlet 125. Water in the collection tank 124 can be guided to the water tank 100 for storage and reuse. The water tank 100 may be provided with a connecting port 110, which is connected to the washing chamber 20. The design of the connecting port 110 allows water in the water tank 100 to be directly introduced into the washing chamber 20, merging with the water flow during the washing process, ensuring smooth and safe water flow.

[0288] Combination Figure 19 As shown, in some possible embodiments, the device mounting portion 73 is provided with a water-blocking protrusion 732, which is arranged around the mounting opening 731. The surrounding water-blocking protrusion 732 can provide a physical barrier to prevent water from entering the enclosure through the mounting opening 731 from all directions.

[0289] The inner side of the water blocking protrusion 732 is used for penetrating the encoder control rod 911. The inner side of the water blocking protrusion 732 is the mounting port 731, and the encoder control rod 911 penetrates in the mounting port 731 and is connected with the knob 80 arranged in the mounting port 731.

[0290] The water blocking protrusion 732 is arranged protruding relative to the device mounting portion 73 in the direction away from the circuit board 91, and the water blocking protrusion 732 can effectively guide the water droplets away from the mounting port 731, reducing the possibility of water entering the inside of the frame 12 through the mounting port 731.

[0291] In combination Figure 21 to Figure 23 As shown in some possible embodiments, the control panel 70 can include an encoder support 95. The encoder support 95 is arranged on the device mounting portion 73. The encoder support 95 is located on the side of the device mounting portion 73 facing the frame 12. The encoder support 95 can be connected with the device mounting portion 73 through a buckle structure, a screw connector or a combination of both.

[0292] For example, the encoder support 95 can be provided with fixed connection portions on both sides in the left-right direction of the cabinet 10. The device mounting portion 73 can be provided with second connection portions 733 corresponding to the fixed connection portions. The first connection portions 954 and the second connection portions 733 can be fixedly connected together through screws.

[0293] The encoder support 95 can be provided with fifth buckle portions 953 on both sides in the up-down direction. The device mounting portion 73 can be provided with clamping grooves 734 corresponding to the fifth buckle portions 953. The fifth buckle portions 953 are correspondingly clamped in the clamping grooves 734.

[0294] The encoder support 95 can be provided with a fixed cavity 951. The fixed cavity 951 has an opening arranged towards the device mounting portion 73. The circuit board 91 is located in the fixed cavity 951. By connecting the circuit board 91 with the encoder support 95, the circuit board 91 can be better supported and fixed; the fixed cavity 951 can reduce the influence of external factors on the circuit board 91, and improve the safety of the circuit board 91.

[0295] For example, the circuit board 91 can be connected with the encoder support 95 through a buckle structure, a screw connector or a combination of both.

[0296] In combination Figure 22 , Figure 25 and Figure 26 As shown in some possible embodiments, the encoder support 95 can be provided with a first clamping port 952. The first clamping port 952 is arranged in the fixed cavity 951, and the first clamping port 952 can be located on the side of the circuit board 91 away from the device mounting plate.

[0297] The knob bracket 94 can be provided with a fourth clamping portion 941. The fourth clamping portion 941 corresponds to the first clamping interface 952. The circuit board 91 can be provided with an avoiding opening 912 corresponding to the fourth clamping portion 941.

[0298] When installing the knob bracket 94, the fourth clamping portion 941 can be first inserted through the avoiding opening 912 on the circuit board 91, so that the fourth clamping portion 941 reaches the side of the circuit board 91 away from the device mounting plate, and then the fourth clamping portion 941 is clamped in correspondence with the first clamping interface 952. The connection mode of the fourth clamping portion 941 and the first clamping interface 952 is simple to assemble, reduces the dependence on traditional fasteners, and can improve the installation efficiency.

[0299] In some embodiments, the knob bracket 94 can also be provided with a sixth limiting portion 944. The sixth limiting portion 944 corresponds to the position of the fourth clamping portion 941. The circuit board 91 can be provided with a first positioning opening 913 corresponding to the sixth limiting portion 944. When the fourth clamping portion 941 is inserted through the avoiding opening 912 on the circuit board 91, the sixth limiting portion 944 is correspondingly inserted into the first positioning opening 913, so as to limit the knob bracket 94, improve the connection accuracy of the knob bracket 94 and the encoder bracket 95, and prevent connection deviation.

[0300] In combination with Figure 25 and Figure 26 shown, in some possible implementations, the knob bracket 94 can be provided with a fifth limiting portion 942. Correspondingly, the circuit board 91 can be provided with a second positioning opening 914 corresponding to the fifth limiting portion 942. The fifth limiting portion 942 is inserted into the second positioning opening 914 on the circuit board 91.

[0301] By providing the fifth limiting portion 942 on the knob bracket 94, the knob bracket 94 can be limited to be installed on the encoder bracket 95 according to the preset position, so as to ensure that the water diversion and drainage direction of the water diversion structure 93 on the knob bracket 94 is correct, that is, the water diversion outlet 933 is located at the bottom of the water diversion structure 93, so as to facilitate the water collected in the water diversion structure 93 to flow to the water diversion outlet 933 under the action of gravity.

[0302] In combination with Figure 24 and Figure 29 shown, in some possible implementations, the knob bracket 94 can be provided with an annular limiting portion 943. The annular limiting portion 943 is located inside the water diversion structure 93. The outer side wall of the annular limiting portion 943 can serve as the side wall of the first water diversion channel 931, and the water in the first water diversion channel 931 cannot enter the annular limiting portion 943.

[0303] The knob support 94 can be provided with a receiving portion 945. The receiving portion 945 is located inside the annular limiting structure. The encoder control rod 911 passes through the receiving portion 945 and is fixedly connected with the knob 80. By rotating the knob 80, the encoder control rod 911 can be driven to rotate relative to the knob support 94.

[0304] The knob 80 can be provided with a third clamping portion 81. The third clamping portion 81 is clamped and matched with the annular limiting portion 943. In this way, the stable connection of the knob 80 and the knob support 94 is achieved. Moreover, since the structure of the annular limiting portion 943 is annular, the knob 80 can also rotate relative to the knob support 94 after being connected with the knob support 94.

[0305] Some embodiments of the present application provide a pulsator washing machine, which comprises a cabinet 11;

[0306] The pulsator washing machine can comprise a surrounding frame 12, which is arranged on the top of the cabinet 11, and has a dropping opening 121;

[0307] The pulsator washing machine can comprise a drum assembly, which is arranged in the cabinet 11 and has a washing cavity 20. A drum opening of the drum assembly is communicated with the washing cavity 20 and faces the dropping opening 121;

[0308] The pulsator washing machine can comprise a control panel 70;

[0309] The control panel 70 can comprise a device mounting portion 73, which is arranged on the top of the surrounding frame 12. The device mounting portion 73 is provided with a mounting opening 731;

[0310] The control panel 70 can comprise a circuit board 91, which is arranged on the side of the device mounting portion 73 facing the surrounding frame 12. The circuit board 91 has a rotatable encoder control rod 911;

[0311] The control panel 70 can comprise a knob support 94, which is arranged on the side of the circuit board 91 facing the device mounting portion 73;

[0312] The control panel 70 can comprise a knob 80, which is connected with the encoder control rod 911 through the mounting opening 731. The knob 80 is movably arranged on the knob support 94 to drive the encoder control rod 911 to rotate relative to the circuit board 91;

[0313] The knob support 94 is provided with a flow guide structure 93, which is located between the mounting opening 731 and the circuit board 91. The flow guide structure 93 is configured to receive water flow from the mounting opening 731 and guide the water flow into the washing cavity 20.

[0314] It is easy to understand that the control panel is an important component of the pulsator washing machine, and the control panel usually includes a device mounting portion and a circuit board located inside the enclosure. The enclosure is provided with movable components such as knobs or buttons, wherein the knobs are connected with the encoder control rods of the circuit board, and the buttons are connected with the processors or other control chips on the circuit board; control signals can be input to the circuit board through the movable components, thereby realizing the function control of the pulsator washing machine.

[0315] However, in the existing control panel pulsator washing machine equipped with display lights, light spillover often occurs between the light points. This problem is particularly prominent when the light points are designed too compactly, i.e., the distance between the light points is relatively close. Light spillover refers to the situation that light from one light point undesirably spills over or spreads to adjacent light points.

[0316] For example, when one light point is on and the other light points around it are off, due to light spillover, the light of the light point will spill over or spread to the other light areas, which will reduce the light that should be concentrated in the light area, resulting in a decrease in the brightness of the light. When one light point is on and the other light points around it are also on, due to light spillover, the light of the light point will spill over or spread to the other light areas, and the light of the other light points around it will also spill over or spread to the light point area, which will cause great confusion and interference in vision, and greatly reduce the display effect of the entire control panel.

[0317] Specifically, when light spills over from one light point and interferes with adjacent light points, the originally clear and distinct light point state indication becomes unclear. Such unclear state indication may confuse the user during operation and make it difficult to accurately determine the current running state of the washing machine or the selected program mode. In addition, light spillover will also damage the overall aesthetics of the control panel.

[0318] Therefore, some embodiments of the present application provide a pulsator washing machine, which includes a control panel, the control panel includes an enclosure and a circuit board; the enclosure is arranged in a frame, and the enclosure and the frame jointly define a mounting space; the circuit board is arranged in the mounting space, and the circuit board is provided with a light emitting component.

[0319] For the light spillover prevention of the pulsator washing machine, the control panel includes a support, the support is arranged on the side of the circuit board away from the frame, the support is provided with a light outlet at the position corresponding to the light emitting component, the light outlet is used for allowing the light emitting component to emit light along the light outlet; in the light emitting direction of the light emitting component, the caliber of the light outlet increases. By arranging the light outlet at the position of the support corresponding to the light emitting component, the light outlet can act as a barrier to effectively separate the light emitting components, allowing the light emitting component to emit light along the corresponding light outlet, thereby reducing the possibility of light spillover from one light emitting component to another light emitting component.

[0320] And, the diameter of the light outlet end away from the circuit board is larger than the diameter of the light outlet end toward the circuit board, which helps focus the light emitted by the light emitting part at the light outlet, and also helps achieve moderate divergence of the light after focusing, thus achieving good light guiding effect. Such arrangement can effectively reduce the brightness loss of the light, and also ensure the brightness and uniformity of the light, thus improving the visual effect of the entire control panel.

[0321] The control panel 70 can include a bracket. The bracket is arranged on the side of the circuit board 91 away from the frame 12. The bracket can be located on the same side of the circuit board 91 as the light emitting part, and the bracket is provided with a light outlet at a position corresponding to the light emitting part. The light outlet can effectively separate the light emitting parts, and can guide the light emitted by the light emitting part corresponding to the light outlet, so that the light emitting part emits light along the corresponding light outlet, reducing the possibility of light "leaking" from one light emitting part to another.

[0322] In combination Figure 23 to Figure 30 As shown in the drawings, in some embodiments, the control panel 70 can include an encoder bracket 95. The encoder bracket 95 is arranged on the device mounting portion 73. The encoder bracket 95 is located on the side of the device mounting portion 73 toward the frame 12. The encoder bracket 95 can be connected to the device mounting portion 73 by a buckle structure, a screw connector or a combination of both.

[0323] For example, the encoder bracket 95 can be provided with a fixed connection portion on each side in the left-right direction of the cabinet 10. The device mounting portion 73 can be provided with a second connection portion 733 at a position corresponding to the fixed connection portion. The first connection portion 954 and the second connection portion 733 can be fixedly connected together by screws.

[0324] The upper and lower sides of the encoder bracket 95 can be respectively provided with a fifth buckle portion 953. The device mounting portion 73 can be provided with a clamping groove 734 at a position corresponding to the fifth buckle portion 953. The fifth buckle portion 953 is correspondingly clamped in the clamping groove 734.

[0325] The encoder bracket 95 can be provided with a fixing cavity 951. The fixing cavity 951 has an opening arranged toward the device mounting portion 73. The circuit board 91 is located in the fixing cavity 951. By connecting the circuit board 91 and the encoder bracket 95, the circuit board 91 can be better supported and fixed; the fixing cavity 951 can reduce the influence of external factors on the circuit board 91, and improve the safety of the circuit board 91.

[0326] For example, the circuit board 91 can be connected to the encoder bracket 95 by a buckle structure, a screw connector or a combination of both.

[0327] In combination Figure 24 And Figure 31As shown, in some possible implementation, the support can comprise a knob support 94. The knob support 94 can provide a mounting space for the knob 80, and ensure that the knob 80 remains stable during operation. The knob 80 can be movably arranged on the knob support 94. The knob 80 can drive the encoder control rod 911 to rotate relative to the knob support 94.

[0328] The knob support 94 can be provided with a plurality of first light outlets 946. The first light outlets 946 allow light emitted by the light emitting member corresponding to the knob support 94 to pass through, thereby achieving a multi-point light source display effect.

[0329] The circuit board 91 can be provided with a plurality of first light emitting members 915. The plurality of first light emitting members 915 can provide a multi-point light source. The plurality of first light emitting members 915 can be arranged around the circumference of the knob support 94, and can achieve a ring-shaped or circumferential light display effect, so that the light is uniformly distributed around the knob 80, thereby achieving a diversified state indication of the function controlled by the knob 80 of the pulsator washing machine.

[0330] In combination Figure 35 As shown, taking the knob support 94 as an example, the diameter of the first light outlet 946 can increase from the end of the first light outlet close to the circuit board to the end of the first light outlet away from the circuit board. By increasing the diameter of the light outlet, the propagation direction of the light can be effectively controlled. The light can be focused at the first light outlet 946, and after focusing, the light can be moderately divergent, thereby achieving a good light guiding effect. Not only can the light loss be effectively reduced, but also the brightness and uniformity of the light can be ensured, thereby improving the visual effect of the entire control panel 70.

[0331] The light outlet can have a small-diameter end. The small-diameter end is the end of the light outlet facing the circuit board 91, and the light emitting member can be arranged inside the small-diameter end of the light outlet. In this way, the incidence angle of the light can be appropriately ensured. The light outlet can also have a large-diameter end. The large-diameter end is the end of the light outlet away from the circuit board 91. The cross-sectional area of the large-diameter end is larger than that of the small-diameter end.

[0332] The light outlet can be provided with a flat inner wall. As can be understood, when light is emitted from one medium (such as air) into another medium (such as the inner wall of the light outlet), reflection will occur. According to the law of reflection, the reflected light, the incident light and the normal line are in the same plane, and the angle between the reflected light and the incident light is equal. Therefore, under the condition that the inner wall of the light outlet is flat, the light can be regularly reflected according to the law of reflection.

[0333] The inner wall of the light outlet itself can not directly produce a light guiding effect, but it can affect the propagation path of the light. The light emitted by the light guiding member inside the small-diameter end will be reflected multiple times on the inner wall of the light outlet according to the law of reflection, and will be emitted along the direction of the large-diameter end of the light outlet. Figure 36The direction indicated by the middle arrow is focused towards the large-diameter end and converges to point to a certain point or area of the large-diameter end, and finally escapes from the large-diameter end along the drawing to achieve the display effect of light.

[0334] In combination Figure 24 and Figure 31 As shown in FIG. 9, in some possible embodiments, the knob holder 94 can have a plurality of first partitions 947. The first partitions 947 are arranged between two adjacent first light outlets 946, and the first partitions 947 are used to physically separate the adjacent first light emitting members 915, effectively limiting the propagation path of the light, and ensuring that the light of each first light emitting member 915 is only displayed in its designated area.

[0335] In combination Figure 36 As shown in FIG. 9, in some embodiments, the thickness of one end of the first partition 947 away from the circuit board 91 is less than the thickness of the other end of the first partition 947 close to the circuit board 91. The distance between the two adjacent first partitions 947 close to the circuit board 91 is small, and the light emitted by the first light emitting member 915 on the circuit board 91 can be focused here. The distance between the two adjacent first partitions 947 away from the circuit board 91 is large, and the focused light can be moderately diverged when it is emitted outward.

[0336] The knob holder 94 can also have an annular inner blocking wall 948. The inner blocking wall 948 is located on the side of the first light outlet 946 towards the axis of the knob holder 94. The knob holder 94 can also have an outer blocking wall 949 coaxially arranged with the inner blocking wall 948. The outer blocking wall 949 is located on the side of the first light outlet 946 away from the axis of the knob holder 94. The inner blocking wall 948, the outer blocking wall 949, and the first partition 947 together surround the first light outlet 946, which can limit the divergence of the light from the side of the first light emitting member 915, and ensure that the light of the first light emitting member 915 is only displayed in the area of the first light outlet 946.

[0337] The first partition 947 can extend in the radial direction of the knob holder 94. Since the knob 80 is circular, the first partition 947 is arranged radially on the side of the knob holder 94, which can better adapt to the shape of the knob 80, so that the first light emitting member 915 corresponds to the indicated position of the knob 80. In the direction from the inside of the knob holder 94 to the outside of the knob holder 94, the width of the first light outlet 946 increases. The increased first light outlet 946 is fan-shaped, and each first light outlet 946 is distributed on the side of the knob holder 94, which can better adapt to the shape of the knob 80 and improve the display effect of the light.

[0338] In combination Figure 22 , Figure 25 and Figure 31As shown, in some embodiments, the encoder bracket 95 can be provided with a first clamping interface 952. The first clamping interface 952 can be arranged in a fixing cavity 951, and the first clamping interface 952 can be located on the side of the circuit board 91 away from the device mounting plate.

[0339] The knob bracket 94 can be provided with a fourth buckling part 941. The fourth buckling part 941 corresponds to the first clamping interface 952. The circuit board 91 can be provided with a avoiding port 912 corresponding to the fourth buckling part 941.

[0340] When installing the knob bracket 94, the fourth buckling part 941 can be first passed through the avoiding port 912 on the circuit board 91, so that the fourth buckling part 941 reaches the side of the circuit board 91 away from the device mounting plate, and then the fourth buckling part 941 is clamped in correspondence with the first clamping interface 952. The connection mode of the fourth buckling part 941 and the first clamping interface 952 is simple to assemble, reduces the dependence on traditional fasteners, and can improve the installation efficiency.

[0341] In some embodiments, the knob bracket 94 can also be provided with a sixth limiting part 944. The sixth limiting part 944 corresponds to the position of the fourth buckling part 941. The circuit board 91 can be provided with a first positioning port 913 corresponding to the sixth limiting part 944. When the fourth buckling part 941 is passed through the avoiding port 912 on the circuit board 91, the sixth limiting part 944 is passed through the first positioning port 913, so as to limit the knob bracket 94, improve the connection accuracy of the knob bracket 94 and the encoder bracket 95, and prevent the connection from deviating.

[0342] As shown in Figure 22 , Figure 25 and Figure 31 , in some possible implementations, the knob bracket 94 can be provided with a fifth limiting part 942. Correspondingly, the circuit board 91 can be provided with a second positioning port 914 corresponding to the fifth limiting part 942. The fifth limiting part 942 is passed through the second positioning port 914 on the circuit board 91. By providing the fifth limiting part 942 on the knob bracket 94, the knob bracket 94 can be limited to be installed on the encoder bracket 95 according to the preset position, so as to ensure that the first light outlet 946 on the knob bracket 94 corresponds to the position of the first light emitting element 915 on the circuit board 91.

[0343] As shown in Figure 31 , Figure 32As shown, in some possible embodiments, the support frame can include a key support frame 92. The key support frame 92 can provide structural support for the keys and provide a basis for the layout of the light-emitting pieces. The key support frame 92 can be provided with a plurality of second light outlets 921. The second light outlets 921 allow light emitted by the light-emitting pieces corresponding to the key support frame to pass through. The circuit board 91 can be provided with a plurality of second light-emitting pieces 916. The plurality of second light-emitting pieces 916 can provide a multi-point light source. The plurality of second light-emitting pieces 916 emit light through the plurality of second light outlets 921, which can achieve state indication and backlight effect of the key area.

[0344] In combination Figure 32 As shown, in some possible embodiments, at least part of the plurality of second light outlets 921 are arranged in an array.

[0345] For example, part of the second light outlets 921 can be arranged in a horizontal linear array. This arrangement has the effect of being neat and uniform, which can facilitate the user to quickly identify and operate the keys belonging to the same functional category, such as selection of washing programs, water temperature adjustment, etc., so that the operation process is more smooth and efficient.

[0346] Part of the second light outlets 921 can be arranged in a vertical linear array. Such a layout can be used to distinguish different categories of functional indications, such as detergent dispensing, additional washing options, etc. Through vertical extension, clear zoning is formed visually, and it can also help the user to quickly locate the required function among many options.

[0347] In some embodiments, part of the second light outlets 921 can be arranged sporadically. The sporadically arranged second light outlets 921 can be used to represent some special functions or options. For example, they can be used to mark special functions such as quick wash, energy-saving mode, silent mode, etc. of the impeller washing machine. Since these functions are not usually frequently used in daily washing, arranging them in a sporadic manner will not interfere with the user's quick identification of commonly used functions, and can provide more personalized and diversified choices for the user.

[0348] By arranging at least part of the plurality of second light outlets 921 in an array, the design achieves backlight effect and consistent state indication of the key area.

[0349] The array arrangement not only improves the visual aesthetics of the control panel 70, but also improves the intuitiveness and convenience of the user in the operation process. This design optimizes the distribution path of the light, reduces the unevenness and mutual interference of the light, and further improves the overall display effect.

[0350] In combination Figure 32As shown, in some possible embodiments, the key support 92 can be provided with second partitions 922. The second partitions 922 are used to physically separate the adjacent second light emitting members 916 in the same column, preventing the light from interfering with each other between the light emitting members, thereby reducing the light leakage phenomenon. By separating the adjacent light emitting members in the same column, the second partitions 922 can effectively limit the propagation path of the light, ensuring that the light of each second light emitting member 916 is only displayed in its designated area, which helps to improve the display clarity of the key area and the accuracy of the function indication.

[0351] In some embodiments, the thickness of the second partitions 922 at the end away from the circuit board 91 is smaller than the thickness of the second partitions 922 at the end close to the circuit board 91. The distance between the ends of the adjacent two second partitions 922 close to the circuit board 91 is small, and the light emitted by the second light emitting member 916 located on the circuit board 91 can be focused at this position. The distance between the ends of the adjacent two second partitions 922 away from the circuit board 91 is large, and the focused light can be moderately diverged when being emitted outward.

[0352] In combination Figure 30 and Figure 32 As shown, in some possible embodiments, the device mounting portion 73 can be provided with light emitting openings 735. The light emitting openings 735 can correspond to the respective light emitting openings. The shape of the light emitting openings 735 can be adapted to the shape of the corresponding light emitting openings. The light emitting openings 735 allow the light of the light emitting members to pass through. The second light emitting members 916 emit light through the light emitting openings 735. The light can be effectively conducted to the outside of the control panel 70, achieving clear state indication and visual effect.

[0353] It can be understood that there can be a gap between the side of the key support 92 facing the device mounting portion 73 and the device mounting portion 73. The light emitted by the second light emitting members 916 needs to pass through the gap to reach the light emitting openings 735 of the device mounting portion 73 to diffuse to the outside of the device mounting portion 73. However, when the light passes through the gap, it can be diffused outward from the gap, causing the light leakage phenomenon.

[0354] In combination Figure 32 As shown, in some possible embodiments, the key support 92 can be provided with extension members 923. The first ends of the extension members 923 are connected with the second partitions 922, and the second ends of the extension members 923 extend away from the circuit board 91. The extension members 923 can deepen the depth of the second light emitting openings 921, improving the light isolation effect. At least part of the extension members 923 is located in the light emitting openings 735. Then the extension members 923 can block the gap between the side of the key support 92 facing the device mounting portion 73 and the device mounting portion 73. When the light passes through this gap, it will be blocked by the extension members 923, effectively avoiding the light leakage phenomenon.

[0355] In combinationFigure 18 and Figure 34 As shown, in some possible embodiments, a light-transmitting seal is provided inside the light-emitting port. For example, the light-transmitting seal can be a sealant. By applying sealant to the light-emitting port, on the one hand, the light-transmitting seal can effectively prevent dust, moisture, and other impurities from entering the light-emitting port, protecting the internal light-emitting components and circuit board 91 and extending their service life; on the other hand, the hot-melted sealant can firmly connect the circuit board 91 and the bracket together, improving the installation stability of the bracket and preventing loosening or displacement during frequent operation. Furthermore, the light-transmitting seal can also ensure effective light transmission, improving the clarity and contrast of the display.

[0356] Combination Figure 33 and Figure 34 As shown, for example, a second card interface 924 can be provided on the periphery of the button bracket 92. Correspondingly, a sixth latching part 955 can be provided on the outer wall of the encoder bracket 95 at a position corresponding to the second card interface 924. The sixth latching part 955 corresponds to the second card interface 924, and the sixth latching part 955 is correspondingly engaged in the second card interface 924.

[0357] By setting the button bracket 92 and encoder bracket 95 to a snap-fit ​​connection, a stable and effective connection can be provided. On the other hand, the snap-fit ​​connection provides a simplified assembly method, reduces reliance on traditional fasteners, and improves assembly efficiency and connection stability.

[0358] When installing the button bracket 92 onto the encoder bracket 95, the button bracket 92 needs to be pressed against the encoder bracket 95 so that the sixth latch 955 engages with the second latch interface 924. However, during the pressing process, the button bracket 92 and the encoder bracket 95 may shift relative to each other, resulting in a connection misalignment.

[0359] In some embodiments, a positioning groove 925 may be provided on the side of the button bracket 92 facing the encoder bracket 95. The positioning groove 925 is used for plug-in connection with the encoder bracket 95 so as to position the button bracket 92 and the encoder bracket 95 during assembly, thereby improving the connection accuracy between the button bracket 92 and the encoder bracket 95 and preventing connection misalignment.

[0360] For example, the positioning groove 925 can be the gap between the reinforcing rib on the side of the button bracket 92 facing the encoder bracket 95 and the side plate of the button bracket 92. The width of the positioning groove 925 can be slightly larger than the side plate of the encoder bracket 95. When the button bracket 92 presses against the encoder bracket 95, the side plate of the encoder bracket 95 can be inserted into the positioning groove 925.

[0361] It can be understood that the knob support 94, the button support 92 and the circuit board 91 are all mounted on the encoder support 95, and the integration degree is high, the modular assembly and installation can be realized, the production efficiency is improved, and the later maintenance and replacement are facilitated.

[0362] In the related art, a pulsator washing machine includes a cabinet, a surrounding frame and a surrounding barrier. The cabinet is a main structure of the pulsator washing machine, and is used to accommodate or support various components of the pulsator washing machine. The surrounding frame is installed on the top of the cabinet, and clothes are put into the pulsator washing machine through a putting opening on the surrounding frame. The surrounding barrier is installed on the top of the surrounding frame, and components such as a knob and a display panel are installed on the surrounding barrier to realize transmission and execution of various operation instructions of the pulsator washing machine. However, after the surrounding barrier is connected to one side of the surrounding frame by a buckle, the other side needs to be manually held by an assembly worker to complete screw installation. This results in a complicated assembly process of the surrounding barrier and the surrounding frame, and low assembly efficiency.

[0363] Therefore, some embodiments of the present application provide a pulsator washing machine including a cabinet, a surrounding frame, a drum assembly and a surrounding barrier. The surrounding frame is arranged on the top of the cabinet, and the surrounding barrier is installed on the surrounding frame. The surrounding barrier includes a front surrounding barrier part and a rear surrounding barrier part, and at least one of the front surrounding barrier part and the rear surrounding barrier part is provided with a fixing structure. A clamping groove part in the fixing structure is clamped with a buckle part on the surrounding frame to limit upward movement of the surrounding barrier in the width direction and the height direction. A limiting part in the fixing structure is abutted with a limiting plug-in part to limit downward movement of the surrounding barrier in the depth direction and the height direction. The clamping groove part and the limiting plug-in part of the surrounding barrier can be used to quickly install the surrounding barrier on the surrounding frame, the assembly process is relatively simple, and the assembly efficiency of the surrounding barrier is improved.

[0364] Referring to FIGS. 1 to 3, Figure 37 Figure 38 As shown in FIGS. 1 to 3, the pulsator washing machine can include a cabinet 11. The cabinet 11 is a housing part of the pulsator washing machine, and important components of the pulsator washing machine, such as a motor, a pulsator, a drum assembly, etc., can be arranged in the cabinet 11.

[0365] It should be noted that when a user stands in front of the pulsator washing machine, a view angle toward the pulsator washing machine is used as a reference. A front side of the user is opposite to a front side of the pulsator washing machine, and the front side of the pulsator washing machine is arranged opposite to a back side of the pulsator washing machine. A left side of the user can be used to indicate a left side of the pulsator washing machine, and a right side of the user can be used to indicate a right side of the pulsator washing machine. A direction parallel to a line connecting the front side and the back side of the pulsator washing machine is defined as a depth direction of the pulsator washing machine, a direction parallel to a line connecting the left side and the right side of the pulsator washing machine is defined as a width direction of the pulsator washing machine, and a direction parallel to a line connecting a bottom and a top of the pulsator washing machine is defined as a height direction of the pulsator washing machine.

[0366] ​The pulsator washing machine can include a surrounding fence 70 for mounting control devices (such as an encoder, a display panel, a knob, and the like). The surrounding fence 70 can be mounted on the top of the surrounding frame 12.

[0367] Referring to Figure 39 The surrounding fence 70 can include a rear surrounding fence portion 72. The rear surrounding fence portion 72 is disposed on the surrounding frame 12, and is located at the rear side of the surrounding fence 70, close to the back of the cabinet 11. The rear surrounding fence portion 72 can provide protection and support for the control devices.

[0368] The surrounding fence 70 can include a front surrounding fence portion 71. The front surrounding fence portion 71 can be disposed on the side of the rear surrounding fence portion 72 away from the back of the cabinet 11. The front surrounding fence portion 71 can provide protection and support for the control devices.

[0369] The surrounding fence 70 can include a device mounting portion 73, which can be connected at one end with the rear surrounding fence portion 72 and at the other end with the front surrounding fence portion 71. The device mounting portion 73 can be mounted with the control devices. The device mounting portion 73 is disposed obliquely, facilitating user operation and viewing of information.

[0370] Referring to Figure 40 and Figure 41 Further, the surrounding frame 12 can be provided with a clamping groove portion 122 and a limiting portion, by which the surrounding fence 70 can be mounted on the surrounding frame 12.

[0371] In some embodiments, the front surrounding fence portion 71 can be provided with a fixing structure 75 (such as a buckle, a groove, a mounting hole, and the like), and the front surrounding fence portion 71 can be connected with the clamping groove portion 122 and the limiting portion through the fixing structure 75 to mount the surrounding fence 70 on the surrounding frame 12.

[0372] In some embodiments, the rear surrounding fence portion 72 can be provided with a fixing structure 75, and the rear surrounding fence portion 72 can be connected with the clamping groove portion 122 and the limiting portion through the fixing structure 75 to mount the surrounding fence 70 on the surrounding frame 12.

[0373] In some embodiments, the front surrounding fence portion 71 and the rear surrounding fence portion 72 can both be provided with a fixing structure 75. The front surrounding fence portion 71 and the rear surrounding fence portion 72 can be connected with the clamping groove portion 122 and the limiting portion through the fixing structure 75 to mount the surrounding fence 70 on the surrounding frame 12.

[0374] Specifically, the fixing structure 75 can include a buckle portion 751, which is buckled with the clamping groove portion 122 on the surrounding frame 12 to restrict the relative movement of the surrounding fence 70 and the surrounding frame 12.

[0375] The fixing structure 75 can include a limiting plug-in portion 752, which abuts against the limiting portion to restrict the relative movement of the surrounding fence 70 and the surrounding frame 12.

[0376] In some embodiments, the buckle portion 751 extends towards the inner side of the drum washing machine to form a protrusion with a buckling function. The buckle portion 751 can be provided with an upward abutting surface. The buckle slot portion 122 can be buckled with the buckle portion 751 through the abutting surface. In this way, the movement of the surrounding barrier 70 in the height direction is limited. The two side surfaces of the buckle portion 751 adjacent to the abutting surface are limited in the width direction by abutting with the buckle slot portion 122.

[0377] In some embodiments, the limiting plug-in portion 752 can be provided with an opening facing downward and towards the surrounding frame 12 to form a plug-in slot 753. The limiting portion of the surrounding frame 12 extends upwards away from one end of the surrounding frame 12, and the limiting portion can be inserted into the plug-in slot 753. By extending the limiting portion of the surrounding frame 12 upwards, the movement of the surrounding barrier 70 in the height direction is limited. The plug-in slot 753 is plugged with the surrounding frame 12, and the side surface of the plug-in slot 753 is limited in the depth direction with the surrounding frame 12.

[0378] Along the width direction of the surrounding barrier 70, the buckle portion 751 and the limiting plug-in portion 752 can be arranged at intervals to disperse the stress of the buckle portion 751 and the limiting plug-in portion 752, and improve the reliability of the surrounding barrier 70.

[0379] By providing at least one of the front surrounding barrier portion 71 and the rear surrounding barrier portion 72 with the fixing structure 75, the buckle portion 751 in the fixing structure 75 can be buckled with the buckle slot portion 122 on the surrounding frame 12, and the limiting plug-in portion 752 in the fixing structure 75 can abut with the limiting portion. By buckling the buckle portion 751 and plugging the limiting plug-in portion 752 of the surrounding barrier 70, the surrounding barrier 70 can be quickly installed on the surrounding frame 12. In this way, the assembly process of the surrounding barrier 70 does not need to rely on installation tools, and the assembly process is relatively simple, which improves the assembly efficiency of the surrounding barrier 70. Compared with first plugging the front surrounding barrier portion 71, then buckling the rear surrounding barrier portion 72 or adjusting the position of the rear surrounding barrier portion 72 to buckle to achieve the installation of the surrounding barrier 70. After aligning the front surrounding barrier portion 71 or the rear surrounding barrier portion 72 with the surrounding frame 12, the surrounding barrier 70 can be quickly installed on the surrounding frame 12 by buckling the buckle portion 751 and plugging the limiting plug-in portion 752, without considering the other side of the surrounding barrier 70. In this way, the assembly time of the surrounding barrier 70 can be saved, and the assembly efficiency of the surrounding barrier 70 can be improved.

[0380] In some embodiments, the fixing structure 75 can be provided with a plurality of buckle portions 751 and a plurality of limiting plug-in portions 752 to ensure the reliability of the installation of the fixing structure 75. During the operation of the drum washing machine, the surrounding barrier 70 can be subjected to forces and vibrations in multiple directions. In this way, the uniformity of the force on the surrounding barrier 70 can be improved, and deformation or loosening of the surrounding barrier 70 can be prevented.

[0381] To avoid stress concentration leading to damage of the enclosure 70, the buckle portion 751 and the limiting plug-in portion 752 in the fixing structure 75 are arranged alternately along the width direction of the impeller washing machine. In this way, the force borne by the enclosure 70 can be dispersed to improve the flatness of the enclosure 70 during installation. For example, along the width direction, a first buckle portion, a first limiting plug-in portion, a second buckle portion, a second limiting plug-in portion, a third buckle portion, and a third limiting plug-in portion are arranged on the enclosure 70 in sequence.

[0382] When the distance between the two adjacent buckle portions 751 and limiting plug-in portions 752 is less than 20 mm, the rigidity of the enclosure 70 can be too large to be assembled easily. Moreover, the small distance between the two adjacent buckle portions 751 and limiting plug-in portions 752 can make the buckle portions 751 and limiting plug-in portions 752 arranged too densely, leading to an increase in the processing and manufacturing cost of the enclosure 70.

[0383] When the distance between the two adjacent buckle portions 751 and limiting plug-in portions 752 is greater than 100 mm, the area between the two adjacent buckle portions 751 and limiting plug-in portions 752 can be protruded or recessed due to lack of support, which reduces the aesthetic appearance of the impeller washing machine. Moreover, the large distance between the two adjacent buckle portions 751 and limiting plug-in portions 752 can cause a gap at the connection between the enclosure 70 and the surrounding frame 12, which increases the risk of water entering the enclosure 70 when water splashes on the surrounding frame 12, thereby leading to failure of the control device.

[0384] Therefore, in some embodiments, the distance between the two adjacent buckle portions 751 and limiting plug-in portions 752 in the fixing structure 75 can be greater than or equal to 20 mm and less than or equal to 100 mm. In this way, the assembly difficulty of the enclosure 70 or the problem of recess can be prevented to ensure the reliability and stability of the installation of the enclosure 70.

[0385] The distance between the two adjacent buckle portions 751 and limiting plug-in portions 752 can be set to 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, or a range formed by any two of them. The numerical value of the distance is set according to actual needs.

[0386] In some embodiments, the enclosure 70 can include a plurality of fixing structures 75 to improve the overall stability and vibration resistance of the enclosure 70. By means of the plurality of fixing structures 75, external forces can be dispersed to reduce stress concentration leading to deformation or damage of the surrounding frame 12.

[0387] The plurality of fixing structures 75 can include a first fixing structure and a second fixing structure. The first fixing structure and the second fixing structure can be arranged at different positions of the enclosure 70. Alternatively, the first fixing structure and the second fixing structure can be arranged as different types of fixing structures 75.

[0388] In some embodiments, the first fixing structure connects one or more slot portions 122 and one or more limiting portions. That is, the frame 12 is provided with multiple structures that connect to the first fixing structure of the enclosure 70, so that the enclosure 70 is mounted on the frame 12. The first fixing structure can improve the stability of the enclosure 70 mounted on the frame 12.

[0389] In some embodiments, the second fixing structure may connect one or more slot portions 122 and one or more limiting portions. Similarly, the frame 12 is provided with multiple structures that connect to the second fixing structure of the enclosure 70, so that the enclosure 70 is mounted on the frame 12. The second fixing structure can ensure improved stability of the enclosure 70 mounted on the frame 12.

[0390] Specifically, refer to Figure 42 and Figure 43 As shown, the frame 12 may be provided with a stop plate, which protrudes from the frame 12 and is close to the front enclosure 71. The frame 12 may be provided with a first slot 1221, which may be made by machining a groove on the stop plate.

[0391] The stop plate can be reused in the third limiting part 1222. This reduces the number of parts on the frame 12, reduces the size of the frame 12, and lowers the processing cost of the frame 12.

[0392] In some embodiments, the front enclosure 71 is the main area for user operation and contact, and its stability and durability need to be ensured. A first fixing structure is provided on the front enclosure 71 to ensure the stability of the enclosure 70. Furthermore, when assembling other components, the first fixing structure on the front enclosure 71 can provide initial support for other components, reducing assembly difficulty.

[0393] Reference Figure 44 As shown, the first snap-fit ​​portion 7511 in the first fixing structure can be located on the surface of the front enclosure portion 71 facing the rear enclosure portion 72, and the first snap-fit ​​portion 7511 can engage with the first slot portion 1221. This enables the enclosure 70 to be connected more quickly, avoids the use of multiple installation tools, and improves the assembly efficiency of the enclosure 70.

[0394] The first buckle part 7511 may be provided with an inclined surface, which may be located on the side away from the front enclosure part 71. This facilitates the installation of the first buckle part 7511 and the first slot part 1221, and improves the assembly efficiency of the enclosure 70.

[0395] The first limiting insertion part 7512 in the first fixed structure can be located on the surface of the front enclosure part 71 facing the rear enclosure part 72, and the first limiting insertion part 7512 can abut against the third limiting part 1222. This enables the enclosure 70 to be connected quickly, avoids the use of multiple installation tools, and improves the assembly efficiency of the enclosure 70.

[0396] Along the width direction of the enclosure 70, the first limiting insertion part 7512 is machined with an insertion groove 753. The insertion groove 753 can be inserted into the stop plate, which can reduce the difficulty of inserting the first limiting insertion part 7512 into the second slot part 1231 and improve its assembly efficiency.

[0397] The first limiting insertion part 7512 can be provided on the front enclosure part 71 and extend to the top to the device mounting part 73. This can enhance the stability of the angle between the device mounting part 73 and the front enclosure part 71 and improve the stability of the connection between the device mounting part 73 and the front enclosure part 71.

[0398] Reference Figure 45 and Figure 46 As shown, the frame 12 may be provided with a second slot 1231. The second slot 1231 is made by machining a groove on the rear side of the frame 12, and has a high degree of integration.

[0399] The frame 12 may be provided with a fourth limiting part 1232, which protrudes from the frame 12 and extends upward to ensure the reliability of the connection.

[0400] In some embodiments, a second fixing structure may be provided on the rear enclosure 72 to ensure the stability of the enclosure 70.

[0401] Reference Figure 47 As shown, the second snap-fit ​​portion 7521 in the second fixing structure can be located on the surface of the rear enclosure portion 72 facing the front enclosure portion 71, and the second snap-fit ​​portion 7521 engages with the second slot portion 1231. This enables faster connection of the enclosure 70, avoids the use of multiple installation tools, and improves the assembly efficiency of the enclosure 70.

[0402] The second buckle part 7521 may be provided with an inclined surface, which may be provided on the side opposite to the front enclosure part 71. This facilitates the installation of the second buckle part 7521 and the second slot part 1231 and improves the assembly efficiency of the enclosure 70.

[0403] The second limiting connector 7522 in the second fixing structure can be located on the surface of the rear enclosure 72 facing the front enclosure 71, and the second limiting connector 7522 abuts against the fourth limiting connector 1232. This enables the enclosure 70 to be connected more quickly, avoids the use of multiple installation tools, and improves the assembly efficiency of the enclosure 70.

[0404] The second limiting plug-in part 7522 can protrude from the rear blocking part 72 and be provided with a plug-in slot 753 with an opening downward. The second clamping groove part 1231 protrudes from the surrounding frame 12, so as to improve the reliability of the plug-in of the second limiting plug-in part 7522 and the fourth limiting part 1232, and facilitate installation.

[0405] In some embodiments, the second fixing structure can further include a fastener. The rear blocking part 72 can be provided with a mounting hole 7523, and the fastener passes through the mounting hole 7523 of the rear blocking part 72 and is connected with the threaded hole of the surrounding frame 12. The fastener can further strengthen the connection strength of the blocking 70 and the surrounding frame 12. In this way, it can prevent cracks from occurring in the connection of the blocking 70 and the surrounding frame 12 in the case of large vibration of the pulsator washing machine.

[0406] For example, the fastener can be a screw or a bolt. Specifically, the fastener can be a pan head screw or a countersunk screw, so as to improve the aesthetics of the pulsator washing machine.

[0407] In some embodiments, the second clamping part 7521, the second limiting plug-in part 7522 and the fastener can be arranged alternately along the width direction of the pulsator washing machine. In this way, stress concentration can be avoided to cause damage to the blocking 70.

[0408] When the distance between the second clamping part 7521, the second limiting plug-in part 7522 and the fastener is less than 20 mm, the rigidity of the blocking 70 can be too large to be assembled. In addition, the distance between the second clamping part 7521, the second limiting plug-in part 7522 and the fastener is too small, which can cause the second clamping part 7521, the second limiting plug-in part 7522 and the fastener to be arranged too densely, resulting in an increase in the processing and manufacturing cost of the blocking 70.

[0409] When the distance between the second clamping part 7521, the second limiting plug-in part 7522 and the fastener is greater than 100 mm, the area between the second clamping part 7521, the second limiting plug-in part 7522 and the fastener can be protruding or concave due to lack of support, which reduces the aesthetics of the pulsator washing machine. In addition, the distance between the second clamping part 7521, the second limiting plug-in part 7522 and the fastener is too large, which can cause a gap to occur at the connection of the blocking 70 and the surrounding frame 12. When water splashes on the surrounding frame 12, the risk of water entering can be increased, thereby causing the control device to fail.

[0410] Therefore, the distance between the second clamping part 7521, the second limiting plug-in part 7522 and the fastener is greater than or equal to 20 mm and less than or equal to 100 mm. In this way, the difficulty of assembling the blocking 70 or the problem of concave can be prevented, so as to ensure the reliability and stability of the installation of the blocking 70.

[0411] The distance between the buckle portion 751 and the limiting plug-in portion 752 can be set to 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, or a range formed by any two of them. The numerical value of the distance is set according to actual needs.

[0412] Some embodiments of the present application also provide another pulsator washing machine, which can include a cabinet 11, a surrounding frame 12, a drum assembly, and a surrounding barrier 70. The surrounding frame 12 can be arranged on the top of the cabinet 11, and the surrounding frame 12 can have a drop port 121. The drum assembly can be arranged in the cabinet, and the drum assembly can have a washing cavity 20. The drum port of the drum assembly can be in communication with the washing cavity 20 and face the drop port 121.

[0413] The surrounding frame 12 can be provided with a buckle portion 751 and a limiting plug-in portion 752. The buckle portion 751 extends towards the inner side of the pulsator washing machine, and the buckle portion 751 is provided with an upward abutting surface. The limiting plug-in portion 752 is arranged with an opening facing the surrounding frame 12. The surrounding barrier 70 can include a front surrounding barrier portion 71 and a rear surrounding barrier portion 72. At least one of the front surrounding barrier portion 71 and the rear surrounding barrier portion 72 can be provided with a fixing structure 75, and the fixing structure 75 can include a clamping groove portion 122 and a limiting portion. The clamping groove portion 122 and the limiting portion are arranged at intervals along the width direction of the surrounding barrier 70. The clamping groove portion 122 is clamped with the buckle portion 751 through the abutting surface of the buckle portion 751 to limit the relative movement of the surrounding barrier 70 and the surrounding frame 12. The limiting portion extends upwards from the end of the surrounding barrier 70 away from the surrounding frame 12, and the limiting portion is inserted into the limiting plug-in portion 752 to limit the relative movement of the surrounding barrier 70 and the surrounding frame 12.

[0414] Through the clamping of the clamping groove portion 122 of the surrounding barrier 70 and the insertion of the limiting portion, the surrounding barrier 70 can be quickly installed on the surrounding frame 12. In this way, the assembly process of the surrounding barrier 70 does not need to rely on installation tools, and the assembly process is relatively simple, which improves the assembly efficiency of the surrounding barrier 70. Compared with the method of first inserting the front surrounding barrier portion 71, then clamping the rear surrounding barrier portion 72 or adjusting the position of the rear surrounding barrier portion 72 before clamping to achieve the installation of the surrounding barrier 70. After aligning the front surrounding barrier portion 71 or the rear surrounding barrier portion 72 with the surrounding frame 12, the surrounding barrier 70 is quickly installed on the surrounding frame 12 through the clamping of the clamping groove portion 122 of the surrounding barrier 70 and the insertion of the limiting portion, without considering the other side of the surrounding barrier 70. This can save the assembly time of the surrounding barrier 70 and improve the assembly efficiency of the surrounding barrier 70. The structures can refer to the descriptions of the features as described above.
