AI Technical Summary
The door cover of the pulsator washing machine does not contact the damper when it is opened to the maximum angle, resulting in an empty stroke problem. The door cover falls freely at a fast speed, affecting the cushioning effect and service life of the damper.
A torsion spring is set at the rotating connection between the door cover and the chassis to provide torsion to prevent the door cover from falling. When the door cover falls to a preset angle, it contacts the damper. The damper provides a reverse damping force. The torsion spring and the damper jointly prevent the door cover from falling, thereby achieving slow closing.
Effectively reduce the speed before the door cover contacts the damper, ensure the buffering effect of the damper, and improve the service life of the damper and user experience.

Technical Field
[0002] The present disclosure relates to the technical field of clothing processing equipment, and in particular to a pulsator washing machine. Background Art
[0003] A pulsator washing machine is a household appliance that uses electrical energy to generate mechanical action to wash clothes. As consumers' living standards improve, their requirements for pulsator washing machines are also getting higher and higher.
[0004] A pulsator washing machine typically consists of a chassis, a drum assembly, and a door. The drum assembly is located within the chassis, forming a washing chamber for washing clothes. The chassis has an open top, and the door is located within this opening to open and close the chassis. A damper is installed on the top of the chassis. When the door closes the top opening, the damper interacts with the door, generating a damping force in the opposite direction of the closing direction, preventing the door from freely falling and colliding with the chassis. Summary of the Invention
[0005] The present disclosure aims to solve the problem of the door cover of a pulsator washing machine falling down.
[0006] The present disclosure provides a pulsator washing machine, which includes a chassis, a door cover, a torsion spring and a damper; the chassis is constructed as an outer shell of the pulsator washing machine; a loading port is provided on the top of the chassis; a washing chamber is formed in the chassis, and the washing chamber is connected to the loading port; the door cover is rotatably provided on the top of the chassis, and the door cover is used to open and close the loading port; the torsion spring is provided at the rotating connection between the door cover and the chassis, one end arm of the torsion spring is connected to the chassis, and the other end arm of the torsion spring is connected to the door cover; a damper, which is provided on the top of the chassis; wherein, when the door cover is opened, the torsion spring can generate torsion, and the torsion of the torsion spring can prevent the door cover from falling; when the door cover falls to a preset angle, the door cover can offset the damper, and the damper can provide a damping force in the opposite direction to the falling of the door cover.
[0007] The above technical solution has the following advantages and positive effects: the door cover is rotatably arranged on the top of the chassis, so that the loading port on the top of the chassis can be opened and closed. A torsion spring is arranged at the rotating connection between the door cover and the chassis. After the door cover is opened, the torsion spring can provide a torque to prevent the door cover from falling. When the door cover is closed from the maximum angle, the torsion force of the torsion spring can first provide resistance to the door cover, so that the door cover slowly falls. When the door cover falls to a preset angle, the door cover can abut against the damper. At this time, the damping force of the damper can jointly prevent the door cover from falling with the torsion force of the torsion spring. The torsion spring can solve the problem of the empty stroke before the door cover contacts the damper, so that the door cover can be closed slowly. In addition, the torsion force of the torsion spring can effectively reduce the speed of the door cover before contacting the damper, which is beneficial to ensure the buffering effect of the damper and increase the service life of the damper.

[0086] In the relevant pulsator washing machine, when the door cover is opened to the maximum angle, the door cover usually does not contact the damper. The door cover needs to drop to a certain angle before it contacts the damper and the damper generates a damping force. Therefore, there is an idle stroke problem before the door cover drops to contact the damper. During the idle stroke, the door cover falls freely, resulting in a faster closing speed of the door cover, which affects the buffering effect and service life of the damper. To solve the above problems, as shown in Figure 1, some embodiments of the present disclosure provide a pulsator washing machine, which may include a chassis 10. The chassis 10 can be constructed as an external shell of the pulsator washing machine. The chassis 10 can generally adopt a rectangular hollow structure.
[0087] It should be noted that, in some other embodiments, the appearance and shape of the chassis 10 can be designed as needed, and no limitation is imposed here. The interior of the chassis 10 can be used to provide an installation space.
[0088] In some embodiments, as shown in Figures 1, 2, and 3, a loading port 121 may be provided on the top side wall of the chassis 10. The loading port 121 may communicate with the interior space of the chassis 10. Clothes may be placed into the chassis 10 through the loading port 121 for washing.
[0089] In some embodiments, as shown in Figures 1, 2, and 3, a door cover 40 may be provided on the top surface of the chassis 10. The door cover 40 may be used to open and close the loading port 121 on the top surface of the chassis 10, and the space inside the chassis 10 may be opened and closed through the door cover 40.
[0090] In some embodiments, as shown in Figures 2 and 3, the door cover 40 is rotatably disposed on the top of the chassis 10. The rear edge of the door cover 40 can be rotatably connected to the top of the chassis 10. The rear edge of the door cover 40 can be rotatably connected to the rear edge of the loading port 121. Therefore, the front end of the door cover 40 can rotate about its rear end. It should be noted that in other embodiments, the door cover 40 can also be rotatably connected to the top of the chassis 10 via other side edges.
[0091] In some embodiments, as shown in Figures 1 and 3, the chassis 1 may include a box body 11 and a frame 12. The top of the box body 11 may be provided with a frame 12. The frame 12 is arranged around the top of the box body 11. The frame 12 may be a rectangular frame structure. The delivery port 121 may be opened at the center of the frame 12. The rear end of the door cover 40 is rotatably provided on the frame 12. The rear end of the door cover 40 can be rotated relative to the frame 12, thereby allowing the front end of the door cover 40 to cover or open the delivery port 121, thereby realizing the opening and closing of the door cover 40, and then opening and closing the delivery port 121 on the frame 12.
[0092] In some embodiments, as shown in Figures 1, 2 and 3, a drum assembly (not shown) may be provided in the chassis 10. The drum assembly may be arranged to extend vertically in the up-down direction. A washing chamber 20 may be formed in the drum assembly. A barrel opening (not shown) may be formed on the top surface of the drum assembly. The barrel opening of the drum assembly may communicate with the interior of the washing chamber 20. The barrel opening of the drum assembly is directly opposite the loading port 121 at the top of the chassis 10 and the door cover 40. The loading port 121 may communicate with the interior of the washing chamber 20. When the door cover 40 is rotated so that the front end of the door cover 40 is raised, the loading port 121 can be opened, and clothes can be sequentially placed into the washing chamber in the drum assembly through the loading port 121 of the chassis 10 and the barrel opening at the top of the drum assembly to perform operations such as washing and dehydrating clothes. When the door cover 40 is rotated so that the front end of the door cover 40 is lowered, the loading port 121 can be closed by the door cover 40, and the door cover 40 can simultaneously close the loading port 121 and the washing chamber.
[0093] In some embodiments, the drum assembly may include an outer drum (not shown). The outer drum may be disposed inside the chassis 10. The outer drum is configured as a tub for accommodating wash water, i.e., the interior space of the outer drum can be used to hold wash liquid, such as water, detergent, softener, etc.
[0094] In some embodiments, the drum assembly may include an inner drum (not shown). A washing chamber may be formed within the inner drum. A water hole may be provided on the peripheral wall of the inner drum. Washing liquid can enter the washing chamber within the inner drum through the water hole. The washing chamber within the inner drum is used to hold clothes to be washed.
[0095] In some embodiments, the inner drum is rotatably disposed within the outer drum. When the inner drum rotates relative to the outer drum, it drives the clothing to rotate relative to the outer drum, thereby washing the clothing within the inner drum's washing chamber and improving the uniformity of washing and dehydrating the clothing. It should be noted that in other embodiments, the washing chamber can also be used to dry clothing, such as in a washer-dryer.
[0096] In some embodiments, the outer cylinder and the inner cylinder can be coaxially arranged inside and outside. The top of the outer cylinder and the top of the inner cylinder can be provided with openings arranged opposite to each other. The top opening of the outer cylinder and the top opening of the inner cylinder can be combined to form the cylinder mouth of the cylinder assembly.
[0097] In some embodiments, a drive device (not shown in the figure), such as a drive motor, may be provided in the chassis 10. The drive device may be provided outside the outer drum. The drive device may be provided inside the chassis 10. The output end of the drive device may extend into the interior of the outer drum and be transmission-connected to the inner drum. When the drive device is able to drive the inner drum to rotate relative to the outer drum, the washing or dehydration function of the washing chamber in the inner drum can be realized. It should be noted that, in some other embodiments, the output end of the drive device may also be transmission-connected to the inner drum via a transmission device.
[0098] In some embodiments, a water-dispelling blade (not shown) may be provided on the inner bottom surface of the inner drum. The output end of the driving device may be in transmission connection with the water-dispelling blade. The driving device can drive the water-dispelling blade to rotate, thereby driving the water and clothing in the inner drum to rotate, thereby achieving the washing function of the washing chamber in the inner drum.
[0099] In some embodiments, as shown in FIG4 , a hinge portion 32 may be protruding from the top surface of the chassis 10. The hinge portion 32 may be protruding from the top surface of the frame 12. A side edge of the door cover 40 may be recessed with a retaining groove 410 disposed opposite the hinge portion 32. The hinge portion 32 rotatably extends into the retaining groove 410. In this manner, the side edge of the door cover 40 can rotate about the axis of the hinge portion 32, thereby allowing the door cover 40 to rotate relative to the top of the chassis 10.
[0100] It should be noted that, in some other embodiments, the hinge portion 32 may be protruding from the side edge of the door cover 40. The avoidance groove 410 may be recessed in the top surface of the chassis 10. The side edge of the door cover 40 can rotate within the avoidance groove 410 via the hinge portion 32, thereby rotating relative to the top of the chassis 10.
[0101] In some embodiments, as shown in Figures 3 and 4, the shaft portion 32 can be disposed at the rear edge of the loading port 121. The avoidance groove 410 can be provided at the rear edge of the door cover 40. The rear edge of the door cover 40 can rotate about the axis of the shaft portion 32.
[0102] It should be noted that, in some other embodiments, the avoidance groove 410 may be provided at the left edge or the right edge of the door cover 40. Correspondingly, the shaft portion 32 may also be arranged at the corresponding side edge of the loading port 121.
[0103] In some embodiments, as shown in Figures 3 and 4 , the top of the chassis 10 may be provided with two hinges 32. The two hinges 32 may be spaced apart on the left and right sides of the top of the chassis 10. The two hinges 32 may be spaced apart coaxially. The axis centers of the two hinges 32 may be coaxial.
[0104] In some embodiments, as shown in Figures 3 and 4, the door cover 40 may be provided with two avoidance grooves 410. The two avoidance grooves 410 may be arranged opposite to the two rotating shaft portions 32. The two rotating shaft portions 32 may be rotatably extended into one of the avoidance grooves 410.
[0105] It should be noted that, in some other embodiments, the number of the rotating shaft portions 32 on the top of the chassis 10 and the number of the avoiding grooves 410 on the door cover 40 can be adjusted as needed, and are not limited here.
[0106] In some embodiments, as shown in Figures 5 and 6 , a damper 50 may be provided on the top of the chassis 10. The damper 50 can be used to provide a damping force for the door cover 40. When the door cover 40 descends and closes, the door cover 40 can contact the damper 50, generating a damping force in the opposite direction of the door cover 40's descent. This damping force can slow the closing speed of the door cover 40, thereby allowing the door cover 40 to descend slowly, preventing the door cover 40 from pinching the user's hand and improving the user experience.
[0107] In some embodiments, as shown in Figures 5, 8, and 10, an abutment portion 411 may be provided protrudingly on the door cover 40. The abutment portion 411 may be provided protrudingly at the rear edge of the door cover 40. The abutment portion 411 may be arranged opposite to the damper 50. During the process of the door cover 40 descending and closing, the abutment portion 411 can abut against the damper 50, and the damper 50 can generate a damping force, providing a damping force in the opposite direction of the descent of the door cover 40. The damping force of the damper 50 acts on the abutment portion 411, thereby slowing down the closing speed of the door cover 40, thereby achieving the effect of slowly descending the door cover 40.
[0108] In some embodiments, as shown in Figures 5 and 6, the abutment portion 411 can be protruding from the bottom surface of the door cover 40. The abutment portion 411 can be located on one side of the axial direction of the avoidance groove 410 of the door cover 40. The damper 50 can be arranged on the same axial side as the rotation shaft portion 32. In this way, when the avoidance groove 410 of the door cover 40 rotates relative to the mounting portion 31, the abutment portion 411 can rotate relative to the damper 50.
[0109] In some embodiments, as shown in Figures 5 and 6, two abutting portions 411 may be provided. The two abutting portions 411 may be respectively provided on opposite sides of the two avoidance grooves 410. Two dampers 50 may be provided. The two dampers 50 may be respectively provided on opposite sides of the two rotating shaft portions 32. The two abutting portions 411 may be arranged opposite to the two dampers 50 respectively. The two abutting portions 411 can respectively abut against the two dampers 50, and the two dampers 50 jointly provide opposite damping forces for the door cover 40. The two abutting portions 411 are provided on opposite sides of the door cover 40, thereby ensuring that the left and right sides of the door cover 40 can maintain a smooth and stable landing during the closing process.
[0110] It should be noted that, in some other embodiments, the two abutting portions 411 may also be respectively disposed on the same side of the two avoiding grooves 410 . Correspondingly, the two dampers 50 may also be respectively disposed on the same side of the two mounting portions 31 .
[0111] In some other embodiments, a plurality of abutting portions 411 may be provided. A plurality of dampers 50 may be provided. The number of abutting portions 411 and dampers 50 may be adjusted as needed and is not limited here.
[0112] In some embodiments, as shown in Figures 8, 10, and 12, the damper 50 may include a cylinder 51. The cylinder 51 may be fixedly disposed on the top of the chassis 10. The cylinder 51 may be fixedly disposed in the surrounding frame 12.
[0113] In some embodiments, as shown in Figures 8, 10, and 12, the damper 50 may include a piston rod 53. The piston rod 53 may be coaxially arranged with the cylinder 51. One end of the piston rod 53 may be movably inserted into the cylinder 51. The other end of the piston rod 53 may extend toward the abutment portion 411. The end of the piston rod 53 extending from the cylinder 51 may be exposed at the top of the chassis 10.
[0114] When the door cover 40 is in the process of descending and closing, the abutting portion 411 can abut against the end of the piston rod 53 extending out of the cylinder 51, thereby pushing the piston rod 53 to move toward the inside of the cylinder 51. The inside of the cylinder 51 can produce a damping force in the opposite direction of the movement of the piston rod 53, and this damping force can act on the abutting portion 411 in the opposite direction through the piston rod 53, thereby hindering the door cover 40 from descending. Since the damper 50 is in the damping state when the door cover 40 covers the delivery port 121, the piston rod 53 can exert a damping force on the door cover 40 to hinder its descent, so that the door cover 40 can slow down its descent speed during its descent, thereby achieving the effect of slowly descending the door cover 40, preventing the door cover 40 from pinching the hand, and improving the user experience.
[0115] In some embodiments, as shown in Figures 8, 10 and 12, the damper 50 can be arranged horizontally. The damper 50 can be extended along the front and rear directions of the chassis 10. The piston rod 53 can be provided at the front end of the cylinder 51. In the process of the door cover 40 descending to close the delivery port 121, the abutment portion 411 can abut against the front end of the piston rod 53, pushing the piston rod 53 to move backward. At this time, the front end of the piston rod 53 can provide a reverse damping force to the abutment portion 411, hindering the front end of the door cover 40 from descending, thereby achieving the effect of slowly descending the door cover 40.
[0116] It should be noted that, in some other embodiments, the damper 50 may also be arranged at an angle. The extending direction of the damper 50 may be at a certain angle to the horizontal direction of the chassis 10, or the extending direction of the damper 50 may be at a certain angle to the front-to-back direction of the chassis 10.
[0117] In some embodiments, as shown in Figures 5, 8, 10, and 12, a damping medium (not shown) may be provided in the damper 50. The damping medium may be provided in the cylinder 51. When the door cover 40 descends to close the delivery port 121, the abutment 411 pushes the piston rod 53 toward the inside of the cylinder 51, compressing the damping medium in the cylinder 51. This allows the damping medium to provide a reverse damping force for the piston rod 53 in the cylinder 51. The damping force is transmitted to the abutment 411 via the piston rod 53, thereby achieving a slow descent effect for the door cover 40.
[0118] 9 and 10 , when the door cover 40 is opened to the maximum angle, the door cover 40 can be separated from the damper 50. At this time, the abutment portion 411 can be separated from the piston rod 53, and the damper 50 does not provide a damping force that prevents the door cover 40 from falling.
[0119] In some embodiments, as shown in Figures 9 and 10, when the door cover 40 descends from the maximum angle, as the door cover 40 rotates, the front end of the door cover 40 can gradually descend, and the abutment portion 411 can rotate toward the piston rod 53 of the damper 50. Thereafter, as the door cover 40 continues to descend, until the door cover 40 descends to a preset angle, the abutment portion 411 can abut against the damper 50, that is, the door cover 40 can abut against the damper 50. At this time, the damper 50 can generate a damping force, and the damper 50 can provide a damping force to the abutment portion 411 of the door cover 40 in the opposite direction of the descent direction, as shown in Figures 11 and 12. Thereafter, as the door cover 40 continues to descend, the damper 50 continues to provide a reverse damping force until the door cover 40 completely closes the delivery port 121, as shown in Figures 7 and 8.
[0120] In some embodiments, as shown in Figures 13, 14, 15, and 16, a mounting member 30 may be provided on the top of the chassis 10. A pivot portion 32 may be protrudingly formed on the top surface of the mounting member 30. The mounting member 30 may be fixed inside the frame 12. The pivot portion 32 may be exposed on the top surface of the frame 12. The pivot portion 32 may be fixed to the top of the frame 12 via the mounting member 30, so that the pivot portion 32 is rotatably connected to the door cover 40.
[0121] In some embodiments, as shown in Figures 15 and 16 , the mounting member 30 can be disposed on one side of the damper 50. The abutment portion 411 can be disposed on one side of the avoidance groove 410 of the door cover 40 in the axial direction. The damper 50 can be arranged on the same axial side as the rotation shaft portion 32. When the door cover 40 rotates relative to the rotation shaft portion 32, the abutment portion 411 can rotate about the axis of the rotation shaft portion 32, causing the abutment portion 411 to abut against the damper 50.
[0122] In some embodiments, as shown in Figures 12 and 16, a fixing portion 34 may be protruding from the side wall of the mounting member 30. The fixing portion 34 may be extended toward one side of the damper 50. The mounting member 30 can be detachably fixed to the top of the chassis 10. The mounting member 30 can be detachably fixed inside the frame 12. When the mounting member 30 is fixed to the top of the chassis 10, the fixing portion 34 may be arranged on the top of the damper 50. The fixing portion 34 can clamp and fix the damper 50 between the bottom surface of the fixing portion 34 and the chassis 10, that is, clamp and fix the damper 50 between the bottom surface of the fixing portion 34 and the frame 12, which can simplify the installation and fixing structure of the damper 50 and simplify the installation difficulty.
[0123] It should be noted that, in some other embodiments, the shielding portion 33 may not be provided on the mounting member 30. For example, the shielding portion 33 may be provided separately on the top of the chassis 10.
[0124] In some embodiments, as shown in Figures 15 and 16 , a mounting groove 13 may be provided on the top surface of the frame 12. The mounting groove 13 may be arranged on the top of the chassis 10. The mounting member 30 may be fixedly mounted in the mounting groove 13.
[0125] In some embodiments, as shown in Figures 13, 15, and 16, the front end of the mounting slot 13 can be exposed on the top surface of the chassis 10. The front end of the mounting slot 13 can also be exposed on the top surface of the surrounding frame 12. The hinge portion 32 can be disposed on the top surface of the front end of the mounting member 30. When the mounting member 30 is fixedly installed in the mounting slot 13, the hinge portion 32 can be exposed on the top surface of the chassis 10, and the hinge portion 32 can also be exposed on the top surface of the surrounding frame 12.
[0126] In some embodiments, as shown in Figures 15 and 16 , a limit slot 14 can be defined on the top surface of the enclosure 12. The limit slot 14 can be installed on the top of the chassis 10. The damper 50 can be installed in the limit slot 14. The limit slot 14 can be located on one side of the mounting slot 13. The limit slot 14 can be located adjacent to the mounting slot 13. The fixing portion 34 can extend into the limit slot 14, thereby clamping the damper 50 in the limit slot 14.
[0127] In some embodiments, as shown in Figures 13, 15 and 16, the front end of the limiting groove 14 can be exposed on the top surface of the chassis 10. The front end of the limiting groove 14 can be exposed on the top surface of the surrounding frame 12. The piston rod 53 can be arranged at the front end of the cylinder 51. The piston rod 53 can be arranged at the front end of the limiting groove 14. The cylinder 51 can be arranged at the rear end of the limiting groove 14. When the damper 50 is fixedly installed in the limiting groove 14, the front end of the piston rod 53 can be exposed on the top surface of the chassis 10, and the front end of the piston rod 53 can be exposed on the top surface of the surrounding frame 12, so that the abutment portion 411 of the door cover 40 can abut against each other.
[0128] In some embodiments, as shown in Figures 13 and 14, a control panel 70 may be provided on the top of the chassis 10. The control panel 70 may be provided on the top of the enclosure 12. The control panel 70 may be provided on the back side of the door cover 40. The control panel 70 may be provided on the top surface of the rear end of the enclosure 12. The control panel 70 may be provided on the back side of the loading port 121. When the control panel 70 is covered on the top surface of the enclosure 12, the control panel 70 may be provided on the top of the mounting groove 13 and the limiting groove 14. The control panel 70 may be provided on the top of the mounting member 30 and the damper 50. The front ends of the mounting groove 13 and the limiting groove 14 may be exposed on the front side of the control panel 70. The rotating shaft portion 32 of the mounting member 30 and the front end of the damper 50 may be exposed on the front side of the control panel 70.
[0129] In some embodiments, as shown in Figures 12 and 18 , a retaining rib 341 may be protruding from the bottom surface of the fixing portion 34. The retaining rib 341 may be disposed at the front end of the cylinder 51. The retaining rib 341 may engage with the rear end wall of the retaining groove 14. The retaining rib 341 may abut against the front end of the cylinder 51, and the rear end wall of the retaining groove 14 may abut against the rear end of the cylinder 51, thereby retaining the cylinder 51 within the retaining groove 14 and preventing the cylinder 51 from moving forward and backward within the retaining groove 14.
[0130] In some embodiments, as shown in Figures 6 and 18 , a torsion spring 45 may be provided between the door cover 40 and the top of the chassis 10. The torsion spring 45 may be used to provide a torsional force. The torsion spring 45 may be arranged at the pivotal connection between the door cover 40 and the chassis 10. One end of the torsion spring 45 may be connected to the chassis 10. The other end of the torsion spring 45 may be connected to the door cover 40.
[0131] In some embodiments, as shown in Figures 9, 11, 17 and 18, after the door cover 40 is opened, the torsion spring 45 can always generate torsion, and the torsion of the torsion spring 45 can prevent the door cover 40 from falling and closing, so that the door cover 40 can fall slowly.
[0132] In some embodiments, as shown in Figures 9, 10, and 18, when the door cover 40 is opened to its maximum angle, the torsion spring 45 can remain against the door cover 40, and the torsion force of the torsion spring 45 can continue to prevent the door cover 40 from falling and closing, allowing the door cover 40 to slowly descend. At this time, the damper 50 can be separated from the door cover 40. The damper 50 no longer provides a damping force to prevent the door cover 40 from descending.
[0133] In some embodiments, as shown in Figures 9, 10, and 18, when the door cover 40 descends from its maximum angle, the torsion force of the torsion spring 45 can continuously prevent the door cover 40 from closing, allowing the door cover 40 to descend slowly. Subsequently, as the door cover 40 continues to descend until it reaches a predetermined angle, it can impact the damper 50. At this point, the reverse damping force generated by the damper 50 and the torsion force of the torsion spring 45 can act together on the door cover 40, hindering its descent and allowing it to descend slowly, as shown in Figures 11 and 12.
[0134] It should be noted that, during the idle stroke from the door cover 40 descending from the maximum angle to the point where the door cover 40 contacts the damper 50, the torsion of the torsion spring 45 can always effectively prevent the door cover 40 from descending, effectively reducing the speed of the door cover 40 before contacting the damper 50, thereby helping to ensure the buffering effect of the damper 50 and improve the service life of the damper 50.
[0135] In some embodiments, as shown in Figures 9, 11 and 18, when the door cover 40 descends, the torsion of the torsion spring 45 can gradually increase as the door cover 40 gradually descends, thereby gradually improving the torsion spring 45's effect on slowing down the door cover 40.
[0136] In some embodiments, as shown in Figures 19 and 20, a torsion spring 45 can be disposed inside the door cover 40. One end of the torsion spring 45 can abut against the inner wall of the door cover 40. The other end of the torsion spring 45 can extend into the avoidance groove 410 and into the shaft portion 32, abutting against the inner wall of the shaft portion 32.
[0137] It should be noted that, in some other embodiments, the main body of the torsion spring 45 may also be disposed within the rotating shaft portion 32.

An open groove 321 may be formed at one axial end of the rotating shaft portion 32. The open groove 321 may communicate with the receiving chamber 300. One end arm of the torsion spring 45 may extend from the open groove 321 into the receiving chamber 300 and abut against the inner wall of the receiving chamber 300.
[0139] In some embodiments, as shown in FIG. 22 , one end of the accommodating cavity 300 away from the axis of the rotating shaft portion 32 may be exposed on the bottom surface of the mounting member 30 , making it convenient to mount and fix one end of the torsion spring 45 in the accommodating cavity 300 .
[0140] In some embodiments, as shown in Figures 18, 21, and 22, a rotating member 46 may be provided within the door cover 40.

[0156] In some embodiments, as shown in Figure 24, a pulsator washing machine may include a drum assembly. The drum assembly is disposed within the housing 10 and includes a washing chamber 20. The washing chamber 20 can be used to hold water and clothes. The drum opening of the drum assembly is connected to the washing chamber 20 and faces the loading port 121, so that clothes loaded through the loading port 121 can enter the washing chamber 20 for washing. In some embodiments, the drum assembly includes an outer drum. The outer drum is disposed within the housing 11, and the drum opening of the outer drum faces the loading port 121.
[0157] In some embodiments, as shown in FIG24 , the drum assembly includes an inner drum 200. The inner drum 200 is rotatably disposed within the outer drum, and the opening of the inner drum 200 may also face the loading port 121.

[0162] In some embodiments, as shown in Figures 25 and 26, the mounting member 30 may include a rotating shaft portion 32. The rotating shaft portion 32 may be protruding from the top of the box body 10. The door cover 40 has a avoidance groove 410 at a position corresponding to the rotating shaft portion 32. The rotating shaft portion 32 may be arranged in the avoidance groove 410. And the two ends of the rotating shaft portion 32 can be rotatably mounted on the groove wall of the avoidance groove 410 directly or indirectly through other adapters to achieve a rotatable connection between the door cover 40 and the mounting member 30. In this way, when the door cover 40 rotates relative to the mounting member 30, it can rotate around the rotating shaft portion 32 to open or close the delivery port 121.
[0163] To meet the demand for large-capacity washing machines, the size of the chassis 10 and the door cover 40 will also be made larger. This will make the door cover 40 heavier. If the door cover 40 closes too quickly during the closing process, it will hit the top of the chassis 10, causing abnormal noise and affecting the user experience.
[0164] According to some embodiments of the present disclosure, in order to improve the user experience, as shown in Figures 26, 27, 28 and 29, the pulsator washing machine may include a damper 50. The door cover assembly may include a damper 50. The damper 50 may be installed on the top of the cabinet 10. During the process of the door cover 40 rotating and closing relative to the chassis 10, the door cover 40 can push the damper 50, and the pushed damper 50 can provide a reverse damping force for the closing of the door cover 40, so as to reduce the closing speed of the door cover 40 and realize the slow-down function of the door cover 40, thereby avoiding abnormal noise during the closing process of the door cover 40 and improving the user experience.
[0165] In some embodiments, as shown in Figures 24, 25, and 26, a limiting groove 14 may be provided on the top of the box body 10. The limiting groove 14 may be formed on the top surface of the surrounding frame 12. The damper 50 may be installed in the limiting groove 14.
[0166] In some embodiments, as shown in FIG26 , the mounting member 30 and the top of the chassis 10 can jointly define a retaining groove 14. In other words, the mounting member 30 and the surrounding frame 12 can jointly define a retaining groove 14. When the damper 50 is disposed in the retaining groove 14, the mounting member 30 can retain the damper 50 in the retaining groove 14.
[0167] In some embodiments, as shown in Figures 25 and 26 , the mounting member 30 may include a mounting portion 31. The mounting portion 31 may be disposed on the top of the chassis 10. The hinge portion 32 may be disposed on a side of the mounting portion 31 facing away from the frame 12. The mounting portion 31 may define a retaining groove 14 together with the top of the chassis 10.
[0168] In some embodiments, as shown in Figures 26, 28, and 29, the frame 12 may have a groove on a side facing away from the chassis 11, and the mounting portion 31 may be disposed within the groove. The mounting portion 31 and the portion of the frame 12 provided with the groove may together form a retaining groove 14. The mounting portion 31 may be connected to the frame 12 using fasteners, etc., to position the mounting portion 31 on the top of the chassis 10. The groove can reduce the installation height of the mounting member 30 on the frame 12. The fasteners may be screws, bolts, or other connecting structures.
[0169] In some other embodiments, the mounting member 30 may also be disposed on the top of the chassis 10 in other ways. For example, the mounting member 30 may be disposed on the top of the chassis 10 in a snap-fit manner.
[0170] For user convenience, in some embodiments, as shown in Figures 24 and 26, the door cover 40 can be provided on the top side of the chassis 10 adjacent to the rear end face 104 of the chassis 10. To this end, the limiting groove 14 is also provided on the top side of the chassis 10 adjacent to the rear end face 104 of the chassis 10, so that when the door cover 40 rotates relative to the chassis 10, it can push the damper 50 to achieve the door cover 40's slow descent function.
[0171] It should be noted that, in some other embodiments, when the door cover 40 is arranged on the side of the top of the chassis 10 adjacent to the left side wall 101 or the right side wall 102, if it is necessary to realize the slow-down function of the door cover 40, the limit groove 14 will also be arranged on the side of the top of the chassis 10 adjacent to the left side wall 101 or the right side wall 102 of the chassis 10, so that the damper 50 can be installed on the top of the chassis 10 and be pushed by the door cover 40 when the door cover 40 rotates.
[0172] The structure of a pulsator washing machine will be further described below by taking the example of the limiting groove 14 being provided on the top of the chassis 10 adjacent to the rear end surface 104 of the chassis 10 .
[0173] In some embodiments, as shown in Figures 28 and 29, the damper 50 may include a damper body 500. The damper body 500 is disposed in the limiting groove 14, and the damper body 500 is located at an end of the limiting groove 14 away from the door cover 40. For example, the damper body 500 may be clamped in the limiting groove 14 to fix the damper body 500 in the limiting groove 14.
[0174] In some embodiments, as shown in Figures 28 and 29, the damper 50 may include a damping portion 52. The damping portion 52 may be located within the limiting slot 14. The damping portion 52 may be located at one end of the limiting slot 14 near the door cover 40. The damping portion 52 is connected to the damper body 500. The door cover 40 is configured such that when the door cover 40 rotates relative to the mounting member 30, the door cover 40 can push the damping portion 52 to move within the limiting slot 14 toward the damper body 500 to limit the rotation of the door cover 40. Specifically, when the damping portion 52 moves within the limiting slot 14 toward the damper body 500, the damping portion 52 can limit the rotation of the door cover 40. By limiting the rotation of the door cover 40 by the damping portion 52, the speed of the door cover 40 during the closing process can be reduced, achieving a slow-down function for the door cover 40, thereby preventing abnormal noise during the closing process of the door cover 40 and improving the user experience.
[0175] In some embodiments, as shown in Figures 27 and 28 , when the mounting portion 31 is disposed on the top of the chassis 10, it can further extend toward the retaining slot 14 to partially cover the notch in the retaining slot 14. In this case, the mounting portion 31 can also restrain the damper body 500 within the retaining slot 14. For example, the mounting portion 31 can have a retaining slot on the side facing the damper body 500, and a portion of the damper body 500 can be disposed within the retaining slot, so that the mounting portion 31 can retain the damper body 500 within the retaining slot 14.
[0176] In some embodiments, as shown in Figures 28 and 29 , the damper body 500 may include a cylinder 51 and a damping medium. The damping medium is disposed in the cylinder 51. The damping portion 52 is connected to the cylinder 51.
[0177] In some embodiments, as shown in Figures 28, 29 and 30, the damper 50 may include a piston rod 53. One end of the piston rod 53 is disposed in the cylinder 51. The other end of the piston rod 53 is connected to the damping portion 52. The damping portion 52 may be disposed at the end of the piston rod 53 away from the cylinder 51. When the damping portion 52 is pushed, the damping portion 52 can move toward the cylinder 51 and push the piston rod 53, so that the piston rod 53 and the damping portion 52 can move toward the movable damper body 500 at the same time to compress the damping medium. After being compressed, the damping medium generates a damping force, which is transmitted to the damping portion 52 through the piston rod 53, so that the damping portion 52 transmits the damping force to the door cover 40. The damping force acts as a resistance to the continued rotation of the door cover 40, which can limit the rotation and closing of the door cover 40, thereby reducing the closing speed of the door cover 40 and realizing the slow descent function of the door cover 40.
[0178] In some embodiments, as shown in Figures 24 and 25, the door cover 40 may have an abutment portion 411 on one side facing the top of the chassis 10, and when the door cover 40 is rotated relative to the chassis 10 and opened to the maximum position, the abutment portion 411 is separated from the damping portion 52.
[0179] In some embodiments, as shown in Figures 24 and 25, during the process of the door cover 40 rotating and closing relative to the chassis 10, the abutment portion 411 rotates along with the door cover 40, can rotate into the limit groove 14, and contact the end of the damping portion 52 away from the damper body 500.
[0180] In some embodiments, as shown in Figures 24 and 25 , as the door cover 40 continues to close, the abutment 411 pushes the damping portion 52 and piston rod 53 within the limiting groove 14 toward the cylinder 51, compressing the damping medium. The damping force generated by the damping medium is transmitted to the abutment 411 via the piston rod 53 and the damping portion 52. This damping force acts as resistance to the continued rotation of the abutment 411, limiting the rotational closure of the door cover 40 and reducing its closing speed during the closing process, thereby achieving a slow-down function for the door cover 40.
[0181] In some embodiments, as shown in Figures 24 and 25 , when the door cover 40 is rotated relative to the chassis 10 from its fully opened position toward the side of the delivery port 121 by a predetermined angle, the abutment portion 411 can contact the end of the damping portion 52 away from the damper body 500. In other words, only after the door cover 40 is rotated from its fully opened position toward the side of the delivery port 121 by the predetermined angle does the abutment portion 411 contact the damping portion 52, thereby achieving the slow-down function of the door cover 40. The predetermined angle can range from 25° to 33°, for example. For example, the predetermined angle can be 28°, 29°, 30°, etc.
[0182] In some embodiments, the angle range in which the door cover 40 rotates from the open position to the maximum position to the contact with the damping part 52 is the idle stroke. The pulsator washing machine can use other damping parts to provide damping force for the door cover 40 in the idle stroke, which can effectively reduce the closing speed of the door cover 40 before the abutment 411 contacts the damping part 52, so as to ensure the damping effect of the damper 50 and improve the service life of the damper 50.
[0183] In some embodiments, as shown in Figures 24 and 25 , the damper 50 is prone to bending and deforming under the push of the abutment portion 411 when being pushed, resulting in unstable damping force and other problems, affecting the slow-down function of the door cover 40. Furthermore, when the damper 50 bends and deforms, it also generates noise, shortening the service life of the damper 50 and other undesirable problems. Therefore, it is necessary to control the bending and deformation of the damper 50.
[0184] Researchers have discovered that the reason the damper 50 bends and deforms under the push of the abutment portion 411 is that the damper 50 moves toward the width or depth of the limiting groove 14 under the push of the abutment portion 411. For example, when the damper 50 moves toward the width of the limiting groove 14 under the push of the abutment portion 411, the damper 50 will bend and deform along the width of the groove. For example, when the damper 50 moves toward the depth of the limiting groove 14 under the push of the abutment portion 411, the damper 50 will bend and deform along the depth of the groove. Therefore, when the movement of the damper 50 toward the width and depth of the limiting groove 14 under the push of the abutment portion 411 is restricted, the bending deformation of the damper 50 can be improved.
[0185] In view of this, as shown in Figures 24, 25 and 26, the pulsator washing machine provided according to some embodiments of the present disclosure improves the structure of at least one of the damping part 52 and the mounting part 30, which can limit the movement of the damper 50 toward at least one of the groove width and groove depth directions of the limiting groove 14 under the push of the abutment part 411, so as to improve the bending deformation of the damper 50, thereby reducing the bending deformation of the damper 50, so as to avoid the damper 50 from having unstable damping force, noise, shortened service life and other adverse problems, so as to enhance the stability of the slow-down function of the door cover 40. At the same time, it can improve the service life of the damper 50 and reduce the noise generated by the damper 50.
[0186] It should be noted that, as shown in Figures 27 and 28, the width and depth of the limiting groove 14 are both perpendicular to the movement direction of the damping portion 52. The movement direction of the damping portion 52 refers to the direction in which the damping portion 52 moves toward the damper body 500, which can be referred to as the X-direction. The width of the limiting groove 14 can be referred to as the Y-direction. The depth of the limiting groove 14 can be referred to as the Z-direction.
[0187] The improvement of the damping portion 52 will be further described below with reference to the accompanying drawings and some embodiments.
[0188] In some embodiments, as shown in Figures 30 and 31 , the sidewall of the damping portion 52 facing the limiting groove 14 has a protruding first limiting portion 521. For example, the first limiting portion 521 can be provided on the sidewall of the damping portion 52 along the width of the limiting groove 14, such that the first limiting portion 521 faces the sidewall of the limiting groove 14. A gap is provided between the first limiting portion 521 and the sidewall of the limiting groove 14. The first limiting portion 521 is used to limit the movement of the damping portion 52 toward the sidewall of the limiting groove 14.
[0189] While maintaining the width of the limiting groove 14, the provision of the first limiting portion 521 can reduce the gap between the damping portion 52 at the location of the first limiting portion 521 and the sidewall of the limiting groove 14. As a result, if the damping portion 52 moves toward the sidewall of the limiting groove 14 under the push of the door cover 40 during its movement toward the damper body 500, the first limiting portion 521 will contact the sidewall of the limiting groove 14 before the remaining structure of the damping portion 52, thereby limiting the movement of the damping portion 52 toward the sidewall of the limiting groove 14. When the movement of the damping portion 52 toward the sidewall of the limiting groove 14 is restricted, the bending deformation of the damping portion 52 toward the sidewall of the limiting groove 14 is minimized, thereby reducing the bending deformation of the damper 50 along the width of the limiting groove 14.
[0190] Since the first limiting portion 521 is a protruding structure on the side wall of the damping portion 52 facing the limiting groove 14, the provision of the first limiting portion 521 in some embodiments of the present disclosure can prevent the damper 50 from bending and deforming toward the side wall of the limiting groove 14, thereby preventing the damper 50 from experiencing unstable damping force, noise, shortened service life, and other undesirable problems. This further enhances the stability of the slow-down 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.
[0191] It should be noted that in some other embodiments, while the width of the limiting groove 14 remains unchanged, the gap between the damping portion 52 and the sidewall of the limiting groove 14 can be reduced by increasing the size of the damping portion 52 in the groove width direction, thereby limiting the movement of the damping portion 52 toward the sidewall of the limiting groove 14. However, when the damping portion 52 moves toward the damper body 500 within the limiting groove 14, if the damping portion 52 deviates toward the sidewall of the limiting groove 14, the entire surface of the damping portion 52 facing the sidewall of the limiting groove 14 will contact the sidewall of the limiting groove 14, resulting in a large area of contact and friction between the damping portion 52 and the sidewall of the limiting groove 14. The damping portion 52 is easily stuck on the groove wall of the limiting groove 14, which is not conducive to the smooth movement of the damping portion 52 within the limiting groove 14 toward the damper body 500, resulting in a jerking feeling during the rotation of the door cover 40. Furthermore, due to manufacturing tolerances, the gap between the damping portion 52 and the sidewall of the retaining groove 14 may fluctuate. If the damping portion 52, while moving toward the damper body 500, also moves toward the sidewall of the retaining groove 14 under the push of the door cover 40, the damping portion 52 may prematurely contact the sidewall of the retaining groove 14 in the area where the gap with the sidewall of the retaining groove 14 increases, becoming stuck there, thus affecting the movement of the damping portion 52 toward the damper body 500.
[0192] Compared to increasing the size of the damping portion 52 in the slot width direction, some embodiments of the present disclosure, through the provision of the first limiting portion 521, can limit the movement of the damping portion 52 toward the sidewall of the limiting slot 14 by simply reducing the gap between the position of the damping portion 52 at the first limiting portion 521 and the sidewall of the limiting slot 14. Furthermore, because the first limiting portion 521 is a local protrusion on the damping portion 52, the gap between the first limiting portion 521 and the sidewall of the limiting slot 14 is easier to control, thereby effectively limiting the movement of the damping portion 52 toward the sidewall of the limiting slot 14.
[0193] In some embodiments, as shown in Figures 31 and 32, the minimum gap between the first limiting portion 521 and the side wall of the limiting groove 14 can be D1. D1 < 0.25mm. For example, D1 can be 0.24mm, 0.23mm, 0.20mm, 0.16mm, 0.13mm, etc. If D1 ≥ 0.25mm, despite the provision of the first limiting portion 521, when the damping portion 52 moves toward or away from the damper body 500, the damping portion 52 will still move toward the side wall of the limiting groove 14 under the push of the door cover 40 or the damping medium, causing bending and deformation.
[0194] Therefore, in some embodiments of the present disclosure, when D1 is less than 0.25 mm, D1 can be made as small as possible on the basis of ensuring that the damping portion 52 moves smoothly toward or away from the damper body 500, so as to prevent the damping portion 52 from bending and deforming when moving toward the side wall of the limiting groove 14 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 portion 52.
[0195] It should be noted that along the width of the limiting groove 14, the side of the first limiting portion 521 facing the side wall of the limiting groove 14 has a point closest to the side wall of the limiting groove 14. The gap between this point and the side wall of the limiting groove 14 can be considered the minimum gap D1. Therefore, the gap between this point and the side wall of the limiting groove 14 facing the limiting groove 14 along the width of the limiting groove 14 is the minimum gap D1.
[0196] In some embodiments, as shown in Figures 30 and 31 , the first limiting portion 521 can be a rectangular block. In this case, the side of the first limiting portion 521 facing the side wall of the limiting groove 14 can be a flat surface, and the end of the first limiting portion 521 facing the damper body 500 will be a right-angled structure. If the first limiting portion 521 is a rectangular block, the end of the first limiting portion 521 facing the damper body 500 will have a distinct edge. In this way, when the damping portion 52 moves toward the side wall of the limiting groove 14 under the push of the door cover 40, the edge of the first limiting portion 521 is easily stuck on the side wall of the limiting groove 14, affecting the movement of the damping portion 52 toward the damper body 500.
[0197] In some embodiments, as shown in Figures 30, 31, and 32, the first limiting portion 521 may have a first guide structure 5211 on one end thereof facing the damper body 500. The first guide structure 5211 has a first guide surface 5212 on the side thereof facing the sidewall of the limiting groove 14. The gap between the first guide surface 5212 and the sidewall of the limiting groove 14 increases as the damping portion 52 moves toward the damper body 500. For example, the gap between the first guide surface 5212 and the sidewall of the limiting groove 14 may gradually increase as the damping portion 52 moves toward the damper body 500. In this way, by setting the first guide structure 5211, the shape of the first limiting portion 521 on the surface facing the side wall of the limiting groove 14 can be changed, so that the first limiting portion 521 has a larger gap between the first guide surface 5212 and the side wall of the limiting groove 14, so as to reduce the contact area between the first limiting portion 521 and the side wall of the limiting groove 14 when the first limiting portion 521 moves toward the side wall of the limiting groove 14.
[0198] In this way, when the damping part 52 moves toward the side wall of the limiting groove 14 under the push of the door cover 40, the remaining position of the first limiting part 521 facing the side wall of the limiting groove 14 will preferentially contact the side wall of the limiting groove 14 to limit the movement of the damping part 52 in the direction of the side wall of the limiting groove 14 when it moves toward the damper body 500, thereby improving the bending deformation of the damper 50 in the slot width direction of the limiting groove 14 when it is pushed to move toward the damper body 500.
[0199] It should be noted that, in some embodiments, the remaining positions of the first limiting portion 521 facing the side wall of the limiting groove 14 include positions of the first limiting portion 521 other than the first guide surface 5212 .
[0200] In addition, since the first limiting portion 521 has a large gap between the first guide surface 5212 and the side wall of the limiting groove 14, when the first limiting portion 521 is in contact with the side wall of the limiting groove 14 at other positions, the first guide surface 5212 will also guide the first limiting portion 521 to move in the direction away from the side wall of the limiting groove 14, so as to avoid the first limiting portion 521 being stuck in the side wall of the limiting groove 14, thereby ensuring that the damping portion 52 moves smoothly toward the damper body 500 when being pushed by the door cover 40.
[0201] In some embodiments, as shown in Figures 30, 31, and 32, the first guide surface 5212 can be an arcuate surface. This arcuate surface can increase the gap between the first guide surface 5212 and the sidewall of the limiting groove 14 along the direction from the damping portion 52 toward the damper body 500. Furthermore, because the first guide surface 5212 is an arcuate surface, the first guide surface 5212 can also be connected to the remaining portion of the sidewall of the first limiting portion 521 facing the limiting groove 14 in an arcuate manner, thereby preventing the first limiting portion 521 from forming edges on the sidewall facing the limiting groove 14, thereby preventing the damping portion 522 from affecting its movement toward the damper body 500.
[0202] In some embodiments, as shown in Figures 30, 31, and 32, the first guide surface 5212 can also be an inclined surface. The inclined surface can also increase the gap between the first guide surface 5212 and the sidewall of the limiting groove 14 along the direction of the damping portion 52 toward the damper body 500. When the inclined surface is connected in an arc shape with the remaining portion of the sidewall of the first limiting portion 521 facing the limiting groove 14, it can also prevent the first limiting portion 521 from forming an edge on the sidewall facing the limiting groove 14, thereby preventing the damping portion 52 from moving toward the damper body 500.
[0203] It should be noted that when the door cover 40 rotates relative to the chassis 10 to open the delivery port 121, the abutting portion 411 of the door cover 40 will disengage from the damping portion 52. At this point, the damping portion 52, driven by the damping medium, will move away from the damper body 500, thereby resetting the damping portion 52 and providing a damping force for the next time the door cover 40 rotates relative to the chassis 10 to close the delivery port 121. Similarly, when the damping portion 52 moves away from the damper body 500 under the force of the damping medium, it may also move toward the sidewall of the limiting slot 14, causing the damping portion 52 to bend and deform.
[0204] To address the above issues, in some embodiments, as shown in Figures 30, 31, and 32, while the first limiting portion 521 includes a first guide structure 5211, the first limiting portion 521 may also include a second guide structure 5213 at the end facing away from the damper body 500. The second guide structure 5213 includes a second guide surface 5214 on the side facing the sidewall of the limiting groove 14. The gap between the second guide surface 5214 and the sidewall of the limiting groove 14 increases along the direction from the damper body 500 to the damping portion 52. For example, the gap between the second guide surface 5214 and the sidewall of the limiting groove 14 may also gradually increase along the direction from the damper body 500 to the damping portion 52. In this way, by setting the second guide structure 5213, the shape of the first limiting portion 521 on the surface facing the side wall of the limiting groove 14 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 14, so as to reduce the contact area between the second limiting portion 522 and the side wall of the limiting groove 14 when the first limiting portion 521 moves toward the side wall of the limiting groove 14.
[0205] In this way, when the damping part 52 moves toward the side away from the damper body 500 and moves toward the side wall of the limiting groove 14 under the push of the damping medium, the first limiting part 521 will preferentially contact the side wall of the limiting groove 14 at the remaining position of the side wall facing the limiting groove 14 to limit the movement of the damping part 52 in the direction of the side wall of the limiting groove 14 when it moves toward the side away from the damper body 500, thereby improving the bending deformation of the damper 50 in the slot width direction of the limiting groove 14 when it is pushed to move toward the side away from the damper body 500.
[0206] In addition, since the first limiting portion 521 has a large gap between the second guide surface 5214 and the side wall of the limiting groove 14, when the first limiting portion 521 contacts the side wall of the limiting groove 14 at other positions, the second guide surface 5214 will also guide the first limiting portion 521 to move in the direction away from the side wall of the limiting groove 14, so as to avoid the first limiting portion 521 being stuck in the side wall of the limiting groove 14, and ensure that the damping portion 52 moves smoothly in the direction away from the damper body 500 when being pushed.
[0207] In some embodiments, as shown in FIG32 , the second guide surface 5214 may also be an arcuate surface or an inclined surface. This arcuate surface or inclined surface can ensure that the gap between the second guide surface 5214 and the sidewall of the limiting groove 14 is increased along the direction from the damper body 500 to the damping portion 52. For details, please refer to the above description of the first guide surface 5212, which will not be repeated here.
[0208] In some embodiments, as shown in FIG. 32 , the second guide structure 5213 and the first guide structure 5211 may be symmetrical structures on the first limiting portion 521 to simplify the structures of the first limiting portion 521 and the damper 50 .
[0209] In some other embodiments, the second guiding structure 5213 and the first guiding structure 5211 may not be symmetrical structures on the first limiting portion 521 .
[0210] It should be noted that because the first guide structure 5211 and the second guide structure 5213 are disposed at both ends of the first limiting portion 521, the gaps between the first limiting portion 521 and the sidewalls of the limiting slot 14 can be increased without affecting the minimum gap D1 between the first limiting portion 521 and the sidewalls of the limiting slot 14, thereby ensuring smooth movement of the damping portion 52 away from or toward the damper body 500. At this point, the middle portion 5215 of the first limiting portion 521 has a point closest to the sidewall of the limiting slot 14 it faces. Along the width of the limiting slot 14, the gap between this point on the middle portion 5215 and the sidewalls of the limiting slot 14 can be considered the minimum gap D1.
[0211] In some embodiments, as shown in Figures 31 and 32, the sidewalls of the retaining groove 14 may include a first sidewall 141 and a second sidewall 142 disposed opposite each other in the groove width direction. The top of the chassis 10 may define the first sidewall 141. The mounting member 30 may define a portion of the second sidewall 142. The damping portion 52 may be provided with a first retaining portion 521 on the sidewall opposite the first sidewall 141. The damping portion 52 may also be provided with a first retaining portion 521 on the sidewall opposite the second sidewall 142.
[0212] When the damping portion 52 moves toward the first side wall 141 under the push of the door cover 40 , the movement of the damping portion 52 toward the first side wall 141 can be limited by a first limiting portion 521 to improve the bending deformation of the damping portion 52 toward the first side wall 141 .
[0213] When the damping portion 52 moves toward the second side wall 142 under the push of the door cover 40 , the movement of the damping portion 52 toward the second side wall 142 can be limited by another first limiting portion 521 to improve the bending deformation of the damping portion 52 toward the second side wall 142 .
[0214] Therefore, through the first limiting portion 521 on the two side walls opposite to the first side wall 141 and the second side wall 142 of the damping portion 52, the damping portion 52 can be prevented from moving toward any side wall in the groove width direction of the limiting groove 14 under the push of the door cover 40 or the damping medium and bending and deforming, so that the damping portion 52 has a better anti-bending and deformation effect in the groove width direction of the limiting groove 14 when being pushed.
[0215] In some embodiments, as shown in Figures 31 and 32 , at least two first position-limiting portions 521 may be spaced apart on the same sidewall of the damping portion 52 in a direction from the damping portion 52 toward the damper body 500. In Figures 31 and 32 , two first position-limiting portions 521 are shown on the same sidewall of the damping portion 52, but this does not limit the number of first position-limiting portions 521.
[0216] For example, in some other embodiments, when there is enough space on the damping portion 52 , three or more first limiting portions 521 may be spaced apart on the same side wall of the damping portion 52 .
[0217] It should be noted that, in some embodiments, only one first limiting portion 521 may be provided on the same side wall of the damping portion 52 .
[0218] Compared with the situation where one first limiting portion 521 is provided on the same side wall of the damping portion 52, by providing at least two first limiting portions 521 spaced apart from each other, when the damping portion 52 moves toward or away from the damper body 500, and when it moves to different positions, the first limiting portion 521 can limit the movement of the damping portion 52 toward the side wall of the limiting groove 14, thereby enhancing the limiting effect of the first limiting portion 521 on the movement of the damping portion 52.
[0219] The improvements of the damping portion 52 and the mounting member 30 will be further described below with reference to the accompanying drawings and some embodiments.
[0220] In some embodiments, as shown in Figures 33 and 34 , the mounting member 30 may include a shielding portion 33. The shielding portion 33 may shield the notch of the limiting groove 14. Thus, when the damping portion 52 moves within the limiting groove 14 to the position where the shielding portion 33 is located, the shielding portion 33 will shield the top of the damping portion 52.
[0221] In some embodiments, as shown in FIG35 , the damping portion 52 is constructed such that when the damping portion 52 is not pushed by the door cover 40, the damping portion 52 and the shielding portion 33 may have an overlapping area S in the height direction of the chassis 10. The height direction of the chassis 10 is parallel to the Z direction. When the damping portion 52 is not pushed by the door cover 40, the position of the damping portion 52 in the limiting groove 14 can be regarded as the initial position. Before the door cover 40 is rotated from the maximum opening position toward the side of the delivery port 121 to the preset angle mentioned above, the position of the damping portion 52 in the limiting groove 14 can be regarded as the initial position.
[0222] It should be noted that if the damping part 52 does not overlap with the shielding part 33 when it is not pushed by the door cover 40, then before the damping part 52 moves toward the damper body 500 to the shielding part 33 under the push of the door cover 40, the damping part 52 is likely to bend and deform toward one side of the shielding part 33, so that the damping part 52 is likely to be stuck on the end face of the shielding part 33 toward the damping part 52, so that the damping part 52 cannot continue to move toward the damper body 500.
[0223] By setting the overlapping area S between the damping part 52 and the shielding part 33 in the height direction of the chassis 10, the damping part 52 in the overlapping area S can be blocked by the shielding part 33 before the damping part 52 moves toward the damper body 500, so as to limit the damping part 52 from bending and deforming when moving toward one side of the shielding part 33 in the groove depth direction, so that the damping part 52 will not be stuck on the end face of the shielding part 33 facing the damping part 52.
[0224] Therefore, some embodiments of the present disclosure can restrict the movement of the damping portion 52 toward the side of the shielding portion 33 by setting the overlapping area S between the damping portion 52 and the shielding portion 33 in the height direction of the chassis 10, and can make the bending deformation of the damping portion 52 toward the side of the shielding portion 33 in the groove depth direction of the limiting groove 14 smaller, and can improve the bending deformation of the damper 50 toward the side of the shielding portion 33 in the groove depth direction of the limiting groove 14, so that the damping portion 52 continues to move toward the damper body 500, thereby enhancing the stability of the slow-descent function of the door cover 40, and further improving the service life of the damper 50 and reducing the noise generated by the damper 50.
[0225] It should be noted that when the damping portion 52 moves toward the shielding portion 33 and abuts against it, the shielding portion 33 can exert a force on the damping portion 52. This force can cause the damping portion 52 to move away from the shielding portion 33, thereby limiting its movement toward the shielding portion 33. For example, when the shielding portion 33 is abutted by the damping portion 52, it can undergo elastic deformation. Compared to a case where the shielding portion 33 does not undergo elastic deformation, elastic deformation of the shielding portion 33 can extend the service life of the mounting member 30.
[0226] Although the overlapping area S between the damping portion 52 and the shielding portion 33 in the height direction of the chassis 10 can prevent the damping portion 52 from getting stuck on the end surface of the shielding portion 33 facing the damping portion 52, when the damping portion 52 moves toward the damper body 500 and into the shielding range of the shielding portion 33, if the damping portion 52 moves toward the shielding portion 33 under the push of the door cover 40, the damping portion 52 may still get stuck on the shielding portion 33.
[0227] To address the above issues, as shown in FIG35 , in some embodiments, the damping portion 52 may have a guide arc 523 at a position corresponding to the overlap region S. The shielding portion 33 may have a guide slope 331, which may face the damping portion 52, with at least a portion of the guide slope 331 located within the overlap region S. The guide slope 331 is configured such that when the damping portion 52 moves toward the shielding portion 33, the guide slope 331 may contact at least a portion of the guide arc 523, thereby limiting movement of the damping portion 52 toward the shielding portion 33. This limits movement of the damping portion 52 toward the shielding portion 33, minimizing bending deformation of the damping portion 52 toward the shielding portion 33 in the depth direction of the limiting groove 14. This, in turn, reduces bending deformation of the damper 50 toward the shielding portion 33 in the depth direction of the limiting groove 14 when the damper 50 is pushed.
[0228] Moreover, by setting the guiding arc surface 523 and the guiding inclined surface 331, when the guiding inclined surface 331 contacts at least part of the guiding arc surface 523, the guiding inclined surface 331 will guide the damping part 52 to move toward the side away from the shielding part 33, so that the damping part 52 continues to move toward the damper body 500.
[0229] In addition, the provision of the guide arc surface 523 can make the edge of the damping portion 52 adjacent to the shielding portion 33 more rounded, thereby preventing the damping portion 52 from getting stuck on the shielding portion 33 when it continues to move toward the damper body 500 over the guide slope 331.
[0230] It should be noted that, in some embodiments, when the damping portion 52 has a first limiting portion 521, and when the damping portion 52 is not pushed by the door cover 40, it has an overlapping area S with the shielding portion 33, while being able to improve the bending deformation of the damper 50 in the groove width direction of the limiting groove 14, it can also improve the bending deformation of the damper 50 in the groove depth direction of the limiting groove 14 toward the shielding portion 33, so that the bending deformation of the damper 50 in the groove width direction and the groove depth direction toward the shielding portion 33 can be effectively controlled at the same time, thereby further enhancing the stability of the slow-descent function of the door cover 40, further improving the service life of the damper 50, and reducing the noise generated by the damper 50.
[0231] In some embodiments, as shown in FIG35 , the size of the overlapping area S along the damping portion 52 toward the damper body 500 may be D2, where D2>1 mm. For example, the size of the overlapping area S may be 1.5 mm, 1.8 mm, 2 mm, and the like. If D2≤1 mm, D2 is relatively small, then the effect of the shielding portion 33 on restricting the movement of the damping portion 52 toward the side of the shielding portion 33 is limited, and the control force of the damper 50 on the bending deformation toward the side of the shielding portion 33 in the groove depth direction is also limited. In contrast, in some embodiments of the present disclosure, by setting D2>1 mm, D2 is relatively large, the effect of the shielding portion 33 on restricting the movement of the damping portion 52 toward the side of the shielding portion 33 is also enhanced, and the control force of the damper 50 on the bending deformation toward the side of the shielding portion 33 in the groove depth direction is also improved.
[0232] In some embodiments, as shown in FIG36 , the angle between the guide bevel 331 and the side of the shielding portion 33 facing away from the notch may be α, and α may satisfy the following: α<45°. For example, α may be 44°, 43°, 35°, 30°, 25°, and the like. Since α affects the slope of the guide bevel 331, when α gradually approaches 90° or 0°, the guide bevel 331 will disappear, and therefore, 0°<α<90°. If α is greater than 45°, the slope of the guide bevel 331 is larger, and the steeper the guide bevel 331 is, the more limited the guiding effect on the damping portion 52 is, and the smoothness of the guide arc surface 523 of the damping portion 52 when moving on the guide bevel 331 is poor. On the other hand, in some embodiments of the present disclosure, by setting α to be less than 45°, the slope of the guiding slope 331 is made smaller, and the flatter the guiding slope 331 is, the better the guiding effect on the damping part 52 is, and it can ensure that the guiding arc surface 523 of the damping part 52 has better smoothness when moving on the guiding slope 331.
[0233] In some embodiments, as shown in FIG36 , α may satisfy the following: 20°<α<45°. α is not necessarily better the smaller it is. For example, when α is less than 20°, the guide slope 331 will be too flat. Only when the guide arc surface 523 of the damping part 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 part 52 toward the side of the shielding part 33. At the same time, when the guide slope 331 is too flat, the shielding part 33 will have a long thin wall at the position of the guide slope 331, which will affect the strength of the shielding part 33. In contrast, in some embodiments of the present disclosure, by setting 20°<α<45°, it can ensure that the guide arc surface 523 of the damping part 52 has better smoothness when moving on the guide slope 331, and can also improve the limiting efficiency of the guide slope 331 on the damping part 52, and can also ensure the strength of the shielding part 33.
[0234] In some embodiments, as shown in FIG37 , the minimum gap between the damping portion 52 and the shielding portion 33 may be D3. The minimum gap D3 is the distance between the damping portion 52 and the shielding portion 33 at the non-guide slope 331. D3 < 0.3 mm. For example, D3 may be 0.25 mm, 0.20 mm, 0.15 mm, 0.1 mm, etc. If D3 ≥ 0.3 mm, the gap (i.e., D3) between the damping portion 52 and the shielding portion 33 at the non-guide slope 331 will be too large, which will still cause the damping portion 52 to move toward or away from the damper body 500, and the damping portion 52 will still be pushed by the door cover 40 or the damping medium to move toward the shielding portion 33 and bend and deform. Therefore, in some embodiments of the present disclosure, by setting D3 to be less than 0.3 mm, D3 can be set as small as possible on the basis of ensuring that the damping portion 52 moves smoothly toward or away from the damper body 500, so as to prevent the damping portion 52 from bending and deforming when moving toward the shielding portion 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 portion 52.
[0235] In some embodiments, as shown in Figures 38 and 39 , the damping portion 52 may have a protruding second stopper 522 on the side facing the bottom wall 143 of the limiting groove 14. A gap may exist between the second stopper 522 and the bottom wall 143 of the limiting groove 14. The second stopper 522 is used to limit the movement of the damping portion 52 toward the bottom wall 143. While the depth of the limiting groove 14 remains unchanged, the provision of the second stopper 522 can reduce the gap between the second stopper 522 and the bottom wall 143. During the movement of the damping portion 52 toward the damper body 500, if the damping portion 52 continues to move toward the bottom wall 143 under the push of the door cover 40, the second stopper 522 will contact the sidewall of the limiting groove 14 before the rest of the damping portion 52, thereby limiting the movement of the damping portion 52 toward the bottom wall 143. When the movement of the damping part 52 toward the bottom wall 143 is restricted, the bending deformation of the damping part 52 toward the bottom wall 143 is small, which can improve the bending deformation of the damper 50 toward the bottom wall 143 in the groove depth direction of the limiting groove 14 when the damper 50 is pushed.
[0236] Since the second limiting portion 522 is a protruding structure on the damping portion 52, some embodiments of the present disclosure can prevent the damper 50 from bending and deforming toward the bottom wall 143 along the groove depth direction through the provision of the second limiting portion 522, thereby avoiding the damper 50 from having adverse problems such as unstable damping force, noise, and shortened service life, so as to enhance the stability of the slow-down function of the door cover 40. At the same time, it can improve the service life of the damper 50 and reduce the noise generated by the damper 50.
[0237] Compared to increasing the size of the damping portion 52 in the groove depth direction, some embodiments of the present disclosure, through the provision of the first limiting portion 521, can limit the movement of the damping portion 52 toward the bottom wall 143 by simply reducing the gap between the location of the second limiting portion 522 and the bottom wall 143. Furthermore, because the second limiting portion 522 is a localized protrusion on the damping portion 52, the gap between the second limiting portion 522 and the bottom wall 143 is easier to control, effectively limiting the movement of the damping portion 52 toward the bottom wall 143. The specific reasons for this can be found in the description of the first limiting portion 521 and will not be elaborated here.
[0238] It should be noted that, in some embodiments, when the damping portion 52 has a first limiting portion 521 and a second limiting portion 522, while improving the bending deformation of the damper 50 in the groove width direction of the limiting groove 14, it can also improve the bending deformation of the damper 50 in the groove depth direction of the limiting groove 14 toward the bottom wall 143, so that the bending deformation of the damper 50 in the groove width direction and the groove depth direction toward the bottom wall 143 can be effectively controlled, so as to further enhance the stability of the slow-down function of the door cover 40. At the same time, it can further improve the service life of the damper 50 and reduce the noise generated by the damper 50.
[0239] It should be noted that, in some embodiments, when the damping portion 52 has a first limiting portion 521 and a second limiting portion 522, and when the damping portion 52 is not pushed by the door cover 40, it has an overlapping area S with the shielding portion 33, while improving the bending deformation of the damper 50 in the groove width direction of the limiting groove 14, it can also improve the bending deformation of the damper 50 in the groove depth direction of the limiting groove 14 toward the shielding portion 33 and the bottom wall 143, and the bending deformation of the damper 50 in the groove width direction and the groove depth direction can be effectively controlled at the same time, thereby further enhancing the stability of the slow-descent function of the door cover 40, further improving the service life of the damper 50, and reducing the noise generated by the damper 50.
[0240] In some embodiments, as shown in FIG37 , the minimum gap between the second stopper 522 and the bottom wall 143 can be D4, where D4 is less than 0.3 mm. For example, D4 can be 0.25 mm, 0.23 mm, 0.20 mm, 0.15 mm, 0.10 mm, etc. If D4 is greater than or equal to 0.3 mm, despite the presence of the second stopper 522, the damping portion 52 will still be pushed toward the bottom wall 143 by the door cover 40 or the damping medium when moving toward or away from the damper body 500, causing the damping portion 52 to bend and deform. Therefore, in some embodiments of the present disclosure, by setting D4 to less than 0.3 mm, D4 can be set as small as possible while ensuring that the damping portion 52 moves smoothly toward or away from the damper body 500, so as to prevent the damping portion 52 from bending and deforming when moving toward the bottom wall 143 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 portion 52.
[0241] It should be noted that, along the depth direction of the limiting groove 14, the surface of the second limiting portion 522 facing the bottom wall 143 has a point closest to the bottom wall 143. The gap between this point and the bottom wall 143 can be considered the minimum gap D4. Therefore, the gap between this point and the bottom wall 143 along the depth direction of the limiting groove 14 is the minimum gap D4.
[0242] In some embodiments, the second limiting portion 522 may also be a rectangular block, similar to the first limiting portion 521. In this case, the end of the second limiting portion 522 facing the damper body 500 will be a right-angle structure.
[0243] It should be noted that when the second limiting portion 522 is a rectangular block, it has a distinct edge. When the damping portion 52 moves toward the bottom wall 143 under the push of the door cover 40, the edge of the second limiting portion 522 is easily stuck on the bottom wall 143, affecting the movement of the damping portion 52 toward or away from the damper body 500.
[0244] To address the above issues, as shown in Figures 38 and 39 , in other embodiments, the second limiting portion 522 may have a third guide structure 5221 at the end facing the damper body 500. The third guide structure 5221 may have a third guide surface 5222 on the side facing the bottom wall 143 of the limiting slot 14. The gap between the third guide surface 5222 and the bottom wall 143 increases as the damping portion 52 moves toward the damper body 500. For example, the gap between the third guide surface 5222 and the bottom wall 143 may gradually increase as the damping portion 52 moves toward the damper body 500. In this way, by setting the third guide structure 5221, the shape of the second limiting portion 522 on the surface facing the bottom wall 143 can be changed, so that the second limiting portion 522 has a larger gap between the third guide surface 5222 and the bottom wall 143, so as to reduce the contact area between the second limiting portion 522 and the bottom wall 143 when the second limiting portion 522 moves toward the bottom wall 143.
[0245] Thus, when the damping portion 52 moves toward the bottom wall 143 under the push of the door cover 40, the remaining portion of the second limiting portion 522 facing the bottom wall 143 will preferentially contact the bottom wall 143, thereby limiting the movement of the damping portion 52 toward the bottom wall 143 when moving toward the damper body 500, thereby improving the bending deformation of the damper 50 toward the bottom wall 143 when moving toward the damper body 500. The remaining portion of the second limiting portion 522 facing the bottom wall 143 includes the portion of the second limiting portion 522 excluding the third guide surface 5222.
[0246] In addition, since the second limiting portion 522 has a large gap between the third guide surface 5222 and the bottom wall 143, when the second limiting portion 522 is in contact with the bottom wall 143 at other positions, the third guide surface 5222 will also guide the second limiting portion 522 to move in a direction away from the bottom wall 143 to avoid the second limiting portion 522 being stuck in the bottom wall 143, thereby ensuring the smooth movement of the damping portion 52 toward the damper body 500.
[0247] In some embodiments, as shown in Figures 38 and 39, the third guide surface 5222 can be an arc-shaped surface so that the gap between the third guide surface 5222 and the bottom wall 143 increases in the direction of the damping portion 52 toward the damper body 500, so as to avoid the first limiting portion 521 from having edges on the side wall facing the limiting groove 14, affecting the movement of the damping portion 52 toward the damper body 500.
[0248] In other embodiments, the third guide surface 5222 may also be an inclined surface, which can also increase the gap between the third guide surface 5222 and the bottom wall 143 along the direction of the damping portion 52 toward the damper body 500. When the inclined surface is connected in an arc shape with the remaining portion of the second limiting portion 522 facing the bottom wall 143, it can also prevent the second limiting portion 522 from having edges on the portion facing the bottom wall 143 that would affect the movement of the damping portion 52 toward the damper body 500.
[0249] 38 and 39 , the second limiting portion 522 may have a fourth guide structure 5223 at the end facing away from the damper body 500 . The fourth guide structure 5223 may have a fourth guide surface 5224 on a side facing the bottom wall 143 .
[0250] In some embodiments, as shown in Figures 38 and 39 , when the second position-limiting portion 522 includes the third guide structure 5221, the second position-limiting portion 522 may also include a fourth guide structure 5223 at the end facing away from the damper body 500. The fourth guide structure 5223 may include a fourth guide surface 5224 on the side facing the bottom wall 143. The gap between the fourth guide surface 5224 and the bottom wall 143 increases along the direction from the damper body 500 to the damping portion 52. For example, the gap between the fourth guide surface 5224 and the bottom wall 143 may also gradually increase along the direction from the damper body 500 to the damping portion 52. In this way, by setting the fourth guide structure 5223, the shape of the first limiting portion 521 on the side facing the side wall of the limiting groove 14 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 143, so as to reduce the contact area between the second limiting portion 522 and the bottom wall 143 when the second limiting portion 522 moves toward the bottom wall 143.
[0251] In this way, when the damping part 52 moves toward the side away from the damper body 500 and moves toward the bottom wall 143 under the push of the damping medium, the second limiting part 522 will preferentially contact the bottom wall 143 at the remaining position facing the bottom wall 143 to limit the movement of the damping part 52 in the direction toward the bottom wall 143 when it moves toward the side away from the damper body 500, thereby improving the bending deformation of the damper 50 in the direction toward the bottom wall 143 when it moves toward the side away from the damper body 500.
[0252] In addition, the fourth guide surface 5224 also guides the second limiting portion 522 to move away from the bottom wall 143 to prevent the second limiting portion 522 from being stuck on the bottom wall 143, ensuring smooth movement of the damping portion 52 away from the side of the damper body 500.
[0253] In some embodiments, as shown in Figures 38 and 39, the fourth guide surface 5224 can have the same structure as the third guide surface 5222. For details, please refer to the above description of the third guide surface 5222 and 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 limiter 522 to simplify the structure of the second limiter 522 and the damper 50.
[0254] In some other embodiments, the third guiding structure 5221 and the fourth guiding structure 5223 may not be symmetrical structures on the second limiting portion 522 .
[0255] It should be noted that because the third guide structure 5221 and the fourth guide structure 5223 are disposed at the two ends of the second limiting portion 522, the gaps between the two ends of the second limiting portion 522 and the bottom wall 143 can be increased without affecting the minimum gap D4 between the second limiting portion 522 and the bottom wall 143, thereby ensuring smooth movement of the damping portion 52 away from or toward the damper body 500. In this case, the second limiting portion 522 has a point closest to the bottom wall 143 in the portion between the third guide structure 5221 and the fourth guide structure 5223. The gap between this point on the second limiting portion 522 and the bottom wall 143 along the depth direction of the limiting slot 14 can be considered the minimum gap D4.
[0256] In some embodiments, as shown in Figures 37, 38, and 39, when the shielding portion 33 blocks the notch of the limiting groove 14, the minimum gaps between the damping portion 52 and the shielding portion 33, and between the damping portion 52 and the bottom wall 143 of the limiting groove 14, can each be less than 0.3 mm. In other words, the minimum gaps D3 and D4 can each be less than 0.3 mm. Thus, by limiting the minimum gaps between the damping portion 52 and the shielding portion 33, and between the damping portion 52 and the bottom wall 143 of the limiting groove 14, movement of the damping portion 52 toward the bottom wall 143 of the limiting groove 14 and toward the shielding portion 33 can be restricted. This improves the bending deformation of the damper 50 in the depth direction of the limiting groove 14, further enhancing the stability of the door cover 40's slow-down function. This can also further improve the service life of the damper 50 and reduce noise generated by the damper 50.
[0257] The control panel is a crucial component of a pulsator washing machine. It typically consists of a component section and a circuit board located inside the enclosure. The enclosure is equipped with movable parts such as knobs and buttons, which connect to control levers on the circuit board to input control signals.
[0258] However, to allow these knobs to be smoothly operated from the outside, the enclosure inevitably requires corresponding mounting openings to allow the knobs to extend beyond the enclosure surface. However, in the daily use of pulsator washing machines, due to frequent contact with water, water stains may accidentally splash onto the control panel and then seep into the enclosure through the mounting openings. Once moisture contacts the circuit board and its critical components, such as the encoder, it can cause serious problems such as moisture and short circuits, seriously interfering with the normal operation of the pulsator washing machine.
[0259] To solve the above technical problems, according to some embodiments of the present disclosure, as shown in Figures 40 and 41, the pulsator washing machine may include a control panel 70.
[0260] In some embodiments, as shown in FIG41 , the control panel 70 may include a device portion 73. Device portion 73 may be disposed on the top of the enclosure 12. Device portion 73 provides a mounting location for components of the pulsator washing machine, positioning the operating area of the washing machine above the enclosure 12. This accommodates the height of the user, allowing the user to operate the washing machine from outside the device portion 73 and select washing machine functions.
[0261] In some embodiments, as shown in Figure 41, the control panel 70 may include a fence. The fence may include a front fence portion 71. The front fence portion 71 may be connected to an end of the device portion 73 near the front side of the chassis 10.
[0262] 41 , the enclosure may include a rear enclosure portion 72. The rear enclosure portion 72 may be connected to an end of the device portion 73 close to the rear side of the chassis 10.
[0263] In some embodiments, as shown in FIG41 , the front enclosure 71, the component portion 73, and the rear enclosure 72 collectively enclose an installation cavity 700. The installation cavity 700 can be used to accommodate and install components of the pulsator washing machine. The front enclosure 71 and the rear enclosure 72 shield and protect the installation cavity 700 from the front and rear sides of the pulsator washing machine, preventing the internal components from direct contact with the outside world.
[0264] In some embodiments, as shown in FIG41 , the front enclosure portion 71 , the device portion 73 and the rear enclosure portion 72 may be an integrally formed structure formed by injection molding or other processing techniques, which can reduce installation difficulty and improve assembly efficiency.
[0265] It should be noted that, in some other embodiments, the front enclosure portion 71, the device portion 73 and the rear enclosure portion 72 may also be split structures, and two adjacent components may be fixedly connected by screws, snaps or other forms to reduce processing difficulty.
[0266] In some embodiments, as shown in Figures 41 and 42, the control panel 70 may include a circuit board 91. The circuit board 91 may receive input from a user interface, such as a knob 80 or a key, and convert the input into specific operating instructions to control various functional components of the pulsator washing machine, such as a motor, a pump, a valve, etc.
[0267] In some embodiments, as shown in Figures 41 and 42, a circuit board 91 can be disposed on a side of the device portion 73 facing the frame 12. The circuit board 91 can be located within the mounting cavity 700. The device portion 73 can provide protection for the circuit board 91, preventing the circuit board 91 from directly contacting the external environment.
[0268] In some embodiments, as shown in Figures 41 and 48 , an encoder may be connected to the circuit board 91. The encoder can be used to detect and control the rotational position, speed, and direction of the knob 80. The encoder may have a rotatable control lever 911. The control lever 911 is connected to the knob 80, and the user can control the rotation of the control lever 911 by rotating the knob 80 to select and switch the operating mode of the pulsator washing machine.
[0269] In some embodiments, as shown in Figures 41 and 42, the control panel 70 may include a knob 80. The knob 80 may be connected to a control rod 911. By rotating the knob 80, the control rod 911 may be driven to rotate relative to the circuit board 91 to select and switch the operating mode of the pulsator washing machine.
[0270] In some embodiments, as shown in Figures 41 and 42 , the control panel 70 may include a first bracket 94. The first bracket 94 may be disposed on the side of the circuit board 91 facing the device portion 73. The first bracket 94 provides a mounting cavity 700 for the knob 80, ensuring that the knob 80 remains stable during operation. The knob 80 is movably mounted on the first bracket 94. The knob 80 drives the control lever 911 to rotate relative to the first bracket 94.
[0271] 42 and 43 , the device portion 73 may be provided with a mounting opening 731. When the knob 80 is connected to the first bracket 94, a portion of the knob 80 may extend through the mounting opening 731 to the outside of the device portion 73 for easy operation by the user.
[0272] It should be noted that there is a gap between the knob 80 and the mounting opening 731 of the device part 73 that can connect the inside and outside of the enclosure. Water stains can easily enter the inside of the enclosure through this gap. Once the moisture comes into contact with the circuit board 91 and important components such as the encoder thereon, it may cause serious problems such as moisture and short circuit, thereby seriously interfering with the normal operation of the pulsator washing machine.
[0273] In some embodiments, as shown in Figures 41 and 46 , a diversion structure 93 can be provided on the first bracket 94. At least a portion of the diversion structure 93 can be oriented toward the mounting opening 731. Water entering the enclosure through the mounting opening 731 will enter the diversion structure 93. The diversion structure 93 is disposed around the periphery of the control rod 911. This can prevent water from contacting the encoder, thereby ensuring a waterproof effect on the encoder.
[0274] In some embodiments, as shown in Figures 41 and 46, the diversion structure 93 has a diversion outlet 933. The diversion outlet 933 can promote the discharge of water in the diversion structure 93, prevent water from accumulating in the diversion structure 93, and have a drainage effect.
[0275] In some embodiments, the diversion outlet 933 can be connected to the washing chamber 20. Water within the diversion structure 93 is then drained through the diversion outlet 933 into the washing chamber 20, preventing it from flowing onto the circuit board 91 or other components, thus achieving a waterproof effect on the circuit board 91 and other components. Furthermore, draining the water into the washing chamber 20 prevents it from flowing onto the ground, reducing the risk of electric shock and improving safety.
[0276] In some embodiments, as shown in Figures 41 and 46, the device portion 73 can be tilted toward the front side of the chassis 10. On the one hand, the tilted device portion 73 can facilitate user operation. On the other hand, the tilted device portion 73 can divert water on its surface so that water does not accumulate on the surface of the device portion 73. In addition, since the first bracket 94 is provided on the device portion 73, the first bracket 94 is also tilted, so that the guide structure 93 on the first bracket 94 is also tilted. The diversion outlet 933 can be located at the bottom of the diversion structure 93, so that the water collected in the diversion structure 93 can be directed to the diversion outlet 933 by gravity to facilitate the discharge of water.
[0277] In some embodiments, as shown in FIG46 , the flow guide structure 93 may include a first flow guide channel 931. The first flow guide channel 931 may be annular and may be disposed around the periphery of the control rod 911. By disposing the first flow guide channel 931 around the control rod 911, water drips directly into the first flow guide channel 931 rather than flowing over the sidewalls of the first flow guide channel 931 and directly contacting the control rod 911, thereby improving the waterproofing effect.
[0278] In some embodiments, as shown in Figures 41 and 46, the guide structure 93 may include a second guide channel 932. The first end of the second guide channel 932 may be connected to the bottom of the first guide channel 931, and the second end of the second guide channel has a guide outlet 933. The second guide channel 932 provides a clear drainage path, guiding water from the bottom of the first guide channel 931 to the guide outlet 933, ensuring that the water can be smoothly discharged into the washing chamber 20 and preventing water accumulation.
[0279] In some embodiments, as shown in Figure 46, the second guide channel 932 can be linear so as to discharge water in the shortest path, avoid water staying in the guide structure 93 for a long time, prevent moisture from invading the circuit board 91 and the control rod 911, and reduce the risk of short circuit and moisture.
[0280] In some embodiments, as shown in Figures 49 and 50, the enclosure 12 may be provided with a liquid collecting trough 124. The liquid collecting trough 124 may be in communication with the diversion structure 93. By providing the liquid collecting trough 124 on the enclosure 12, water discharged from the diversion outlet 933 of the diversion structure 93 can be collected in the liquid collecting trough 124, reducing the possibility of water contacting other components.
[0281] In some embodiments, as shown in Figures 49 and 50, the sump 124 may have a liquid outlet 125. The design of the liquid outlet 125 allows the water in the sump 124 to be effectively drained. The liquid outlet 125 is connected to the washing chamber 20, and the water can be directly introduced into the washing chamber 20 and merged with the water flow during the washing process.
[0282] In some embodiments, as shown in Figures 40 and 50 , the pulsator washing machine may further include a water box 100. The water box 100 may serve as an intermediate storage and conditioning device and may be connected to the water inlet of the pulsator washing machine. The water box 100 can receive and store incoming water and release it when needed, helping to better control water usage and distribution during the washing process.
[0283] In some embodiments, as shown in FIG50 , the water box 100 can be connected to a liquid outlet 125. Water in the sump 124 can be directed to the water box 100 for storage and reuse. The water box 100 can be provided with a communication port 110 that communicates with the washing chamber 20. The design of the communication port 110 allows the water in the water box 100 to be directly introduced into the washing chamber 20, where it merges with the water flow during the washing process, ensuring smooth and safe water flow.
[0284] In some embodiments, as shown in Figures 41 and 52, the device portion 73 is provided with a water retaining portion 732, and the water retaining portion 732 is arranged in a ring inside the installation opening 731. The water retaining portion 732 can be a water retaining protrusion, and the water retaining protrusion can be protruded on the surface of the device portion 73. The ring-shaped water retaining portion 732 can provide a physical barrier to prevent water from passing through the installation opening 731 and entering the interior of the enclosure from all directions. The inner side of the water retaining portion 732 can be used to pass through the control rod 911. The inner side of the water retaining portion 732 is the installation opening 731, and the control rod 911 is passed through the installation opening 731 and is connected to the knob 80 that is also provided in the installation opening 731.
[0285] 41 and 52 , the water retaining portion 732 may protrude relative to the device portion 73 in a direction away from the circuit board 91. The water retaining portion 732 can effectively guide water droplets away from the mounting opening 731, thereby reducing the possibility of water entering the interior of the enclosure 12 through the mounting opening 731.
[0286] In some embodiments, as shown in Figures 41 and 44, the control panel 70 may include a second bracket 95. The second bracket 95 is disposed on the device portion 73. The second bracket 95 may be located on a side of the device portion 73 facing the surrounding frame 12. The second bracket 95 may be connected to the device portion 73 using a snap-fit structure, a screw connection, or a combination of the two.
[0287] In some embodiments, as shown in Figures 43 and 44, first connecting portions 954 may be provided on both sides of the second bracket 95 along the left and right directions of the chassis 10. Second connecting portions 733 are provided at positions of the device portion 73 corresponding to the first connecting portions 954. The first connecting portions 954 and the second connecting portions 733 may be fixedly connected together by screws.
[0288] In some embodiments, as shown in Figures 43 and 44 , fifth latch portions 953 may be provided on both sides of the second bracket 95 in the upper and lower directions. A snap-fitting groove 734 may be provided at the position of the device portion 73 corresponding to the fifth latch portion 953. The fifth latch portion 953 may be snap-fitted into the corresponding snap-fitting groove 734.
[0289] In some embodiments, as shown in Figures 41 and 44 , the second bracket 95 can be provided with a fixing cavity 951. The fixing cavity 951 can have an opening facing the device portion 73. The circuit board 91 is positioned within the fixing cavity 951. By connecting the circuit board 91 to the second bracket 95, the circuit board 91 can be better supported and secured. The fixing cavity 951 can reduce the impact of external factors on the circuit board 91, thereby improving the safety of the circuit board 91.
[0290] In some embodiments, the circuit board 91 can be connected to the second bracket 95 through a snap-fit structure, a screw connection, or a combination of the two.
[0291] In some embodiments, as shown in Figures 44, 47, and 48, the second bracket 95 can be provided with a first card interface 952. The first card interface 952 is disposed within the fixing cavity 951 and can be located on the side of the circuit board 91 facing away from the device portion 73. The first bracket 94 can be provided with a fourth snap portion 941. The fourth snap portion 941 corresponds to the first card interface 952. The circuit board 91 can be provided with an escape opening 912, which corresponds to the fourth snap portion 941.
[0292] When installing the first bracket 94, the fourth snap portion 941 can be first passed through the avoidance opening 912 on the circuit board 91, so that the fourth snap portion 941 reaches the side of the circuit board 91 facing away from the device portion 73. The fourth snap portion 941 is then snapped into engagement with the first snap interface 952. This snap connection between the fourth snap portion 941 and the first snap interface 952 simplifies assembly, reduces reliance on traditional fasteners, and improves installation efficiency.
[0293] In some embodiments, as shown in Figures 47 and 48, the first bracket 94 may also be provided with a sixth limiting portion 944. The sixth limiting portion 944 corresponds to the position of the fourth latch portion 941. The circuit board 91 may be provided with a first positioning opening 913 corresponding to the sixth limiting portion 944. When the fourth latch portion 941 is inserted into the avoidance opening 912 on the circuit board 91, the sixth limiting portion 944 is correspondingly inserted into the first positioning opening 913 to restrict the first bracket 94, improve the connection accuracy between the first bracket 94 and the second bracket 95, and prevent the connection from shifting.
[0294] In some embodiments, as shown in Figures 46, 47 and 48, the first bracket 94 may be provided with a fifth limiting portion 942. Correspondingly, a second positioning opening 914 corresponding to the fifth limiting portion 942 may be provided on the circuit board 91. The fifth limiting portion 942 may be inserted into the second positioning opening 914 on the circuit board 91. By providing the fifth limiting portion 942 on the first bracket 94, the first bracket 94 can be restricted from being installed on the second bracket 95 according to a preset position, thereby ensuring that the diversion and drainage directions of the diversion structure 93 on the first bracket 94 are correct, that is, the diversion outlet 933 is located at the bottom of the diversion structure 93, so that the water collected in the diversion structure 93 is directed to the diversion outlet 933 under the action of gravity.
[0295] In some embodiments, as shown in Figures 46 and 47 , the first bracket 94 may be provided with an annular portion 943. The annular portion 943 may be located inside the flow guide structure 93. The outer wall of the annular portion 943 may serve as the side wall of the first flow guide channel 931, and water in the first flow guide channel 931 cannot enter the annular portion 943.
[0296] In some embodiments, as shown in Figures 42, 46, and 48, the first bracket 94 can be provided with a receiving portion 945. The receiving portion 945 is located inside the annular portion 943. The control rod 911 is inserted into the receiving portion 945 and fixedly connected to the knob 80. Rotating the knob 80 can cause the control rod 911 to rotate relative to the first bracket 94.
[0297] In some embodiments, as shown in Figures 42, 46, and 51, the knob 80 may be provided with a third snap-fit portion 81. The third snap-fit portion 81 snaps into engagement with the annular portion 943. This arrangement provides a secure connection between the knob 80 and the first bracket 94. Furthermore, due to the annular shape of the annular portion 943, the knob 80 can rotate relative to the first bracket 94 after being connected.
[0298] According to some embodiments of the present disclosure, a pulsator washing machine is provided. The pulsator washing machine may include a housing 11, a frame 12, a drum assembly, and a control panel 70. The frame 12 may be disposed at the top of the housing 11 and may have a water inlet 121. The drum assembly is disposed within the housing 11 and may have a washing chamber 20. The drum opening of the drum assembly communicates with the washing chamber 20 and faces the water inlet 121. The control panel 70 may include a device portion 73, a circuit board 91, a first bracket 94, and a knob 80. The device portion 73 may be disposed at the top of the frame 12. The device portion 73 may have a mounting opening 731. The circuit board 91 may be disposed on a side of the device portion 73 facing the frame 12. The circuit board 91 may have a rotatable control lever 911. The first bracket 94 may be disposed on a side of the circuit board 91 facing the device portion 73. The knob 80 may be connected to the control lever 911 through the mounting opening 731. The knob 80 may be movably mounted on the first bracket 94 to drive the control lever 911 to rotate relative to the circuit board 91. The first bracket 94 may be provided with a guide structure 93 , which is located between the installation opening 731 and the circuit board 91 . The guide structure 93 is configured to receive water flow from the installation opening 731 and guide the water flow into the washing chamber 20 .
[0299] According to some embodiments of the present disclosure, a pulsator washing machine is provided, which may include a housing 11, a frame 12, a drum assembly, a water box 100, and a control panel 70. The frame 12 may be disposed at the top of the housing 11 and may have a water inlet 121. The frame 12 may have a liquid collection tank 124 and a liquid outlet 125. The drum assembly is disposed within the housing 11 and may have a washing chamber 20. The drum opening of the drum assembly communicates with the washing chamber 20 and faces the water inlet 121. The water box 100 may be provided with a communication port 110. The water box 100 may communicate with the liquid outlet 125. The water box 100 may communicate with the washing chamber 20 through the communication port 110. The control panel 70 may include a device portion 73, a circuit board 91, a first bracket 94, and a knob 80. The device portion 73 may be disposed at the top of the frame 12 and may have a mounting port 731. The circuit board 91 can be mounted on the side of the device portion 73 facing the frame 12. The circuit board 91 has a rotatable control rod 911. A first bracket 94 can be mounted on the side of the circuit board 91 facing the device portion 73. The knob 80 is connected to the control rod 911 through the mounting opening 731. The knob 80 is movably mounted on the first bracket 94 to drive the control rod 911 to rotate relative to the circuit board 91. The first bracket 94 is provided with a diversion structure 93. The diversion structure 93 is arranged around the periphery of the control rod 911, with at least a portion of the diversion structure 93 facing the mounting opening 731. The diversion structure 93 has a diversion outlet 933, which is connected to the liquid collection tank 124.
[0300] By providing a diversion structure 93 on the first bracket 94, water entering the control panel 70 can be diverted and drained. Water entering the control panel 70 through the mounting opening 731 enters the diversion structure 93, preventing it from flowing toward the encoder and ensuring its waterproofing. Furthermore, water within the diversion structure 93 is discharged into the sump 124 through the diversion outlet 933, preventing it from flowing onto the circuit board 91 or other components, ensuring its waterproofing. Water entering the sump 124 can be directed to the water box 100 for storage or reuse. The water box 100 serves as an intermediate storage and regulation device, receiving and storing incoming water and releasing it when needed, helping to better control water usage and distribution during the wash process. Water entering the water box 100 is then directly introduced into the wash chamber 20, where it merges with the water flow during the wash process, ensuring smooth and safe water flow. Furthermore, draining the water into the wash chamber 20 prevents it from flowing onto the ground, reducing the risk of electric shock and improving safety.
[0301] In existing pulsator washing machines equipped with control panels and display lights, light crosstalk often occurs between light points. This problem is particularly prominent when the light points are too closely spaced. Light crosstalk occurs when light from one light point overflows or spreads undesirably to an adjacent light point.
[0302] For example, when a light point is on and other lights around it are off, due to light crosstalk, the light from that light point will overflow or diffuse into other light areas, reducing the light that should be concentrated in that light area and causing a decrease in the brightness of that light. When a light point is on and other lights around it are also on, due to light crosstalk, the light from that light point will overflow or diffuse into other light areas, and the light from other lights around it will also overflow or diffuse into the area of that light point, which will cause great visual confusion and interference, greatly reducing the display effect of the entire control panel.
[0303] Specifically, when light spills from one light spot and interferes with adjacent light spots, the status indicators, which should be clear and distinct, become blurred. This ambiguous status indication can confuse users, making it difficult to accurately determine the current operating status of the washing machine or the selected program mode. Furthermore, light spillage can detract from the overall aesthetics of the control panel.
[0304] To solve the above problems, some embodiments of the present disclosure provide a pulsator washing machine, as shown in Figures 24, 41, 52 and 53, which may include a housing 11, a frame 12, a drum assembly and a control panel 70. The frame 12 may be arranged at the top of the housing 11. The drum assembly is arranged in the housing 11, and the drum assembly has a washing chamber 20. The barrel mouth of the drum assembly is connected to the washing chamber 20 and faces the delivery port 121. The control panel 70 may define an installation cavity 700 together with the frame 12; the installation cavity 700 may be formed between the control panel 70 and the frame 12. The control panel 70 may include a circuit board 91. The circuit board 91 may be arranged in the installation cavity 700, and the circuit board 91 is provided with a light-emitting component.
[0305] In some embodiments, to prevent light leakage in a pulsator washing machine, the control panel 70 includes a bracket. The bracket can be positioned on the side of the circuit board 91 facing away from the frame 12. The bracket can be provided with a light outlet at a position corresponding to the light-emitting element, which is used to direct the light-emitting element to emit light along the light outlet. The diameter of the light outlet increases in the direction of light emission from the light-emitting element. By providing the light outlet at the position corresponding to the light-emitting element in the bracket, the light outlet can act as a barrier, effectively separating the individual light-emitting elements, forcing them to emit light along their corresponding light outlets, thereby reducing the possibility of light "leaking" from one light-emitting element to another. Furthermore, the diameter of the light outlet at the end facing away from the circuit board 91 is larger than the diameter of the light outlet at the end facing the circuit board. This helps focus the light emitted by the light-emitting element at the light outlet and also achieves moderate divergence of the light after focusing, achieving a good light-guiding effect. This arrangement not only effectively reduces light brightness loss but also ensures the brightness and uniformity of the light, improving the visual effect of the entire control panel.
[0306] In some embodiments, as shown in FIG41 , the control panel 70 may include a device portion 73. Device portion 73 may be disposed on the top of the enclosure 12. Device portion 73 provides a mounting location for components of the pulsator washing machine, positioning the operating area of the washing machine above the enclosure 12. This accommodates the height of the user, allowing the user to operate the washing machine from outside the device portion 73 and select washing machine functions.
[0307] In some embodiments, as shown in Figure 41, the control panel 70 may include a fence. The fence may include a front fence portion 71. The front fence portion 71 may be connected to an end of the device portion 73 near the front side of the chassis 10.
[0308] 41 , the enclosure may include a rear enclosure portion 72. The rear enclosure portion 72 may be connected to an end of the device portion 73 close to the rear side of the chassis 10.
[0309] In some embodiments, as shown in FIG41 , the front enclosure 71, the component portion 73, and the rear enclosure 72 collectively enclose an installation cavity 700. The installation cavity 700 can be used to accommodate and install components of the pulsator washing machine. The front enclosure 71 and the rear enclosure 72 shield and protect the installation cavity 700 from the front and rear sides of the pulsator washing machine, preventing the internal components from direct contact with the outside world.
[0310] In some embodiments, as shown in Figures 46, 52 and 53, the bracket may include a first bracket 94. The first bracket 94 may be arranged on the side of the circuit board 91 facing away from the frame 12. The first bracket 94 can provide an installation space for the knob 80 to ensure that the knob 80 remains stable during operation. The knob 80 is movably arranged on the first bracket 94. The knob 80 drives the control rod 911 to rotate relative to the first bracket 94. The first bracket 94 may be provided with a plurality of first light outlets 946. The first light outlets 946 allow light emitted by the light-emitting component corresponding to the first bracket 94 to pass through, thereby achieving a display effect of multiple light sources.
[0311] In some embodiments, as shown in Figures 46, 52, and 53, the circuit board 91 may be provided with multiple first light-emitting elements 915. The light-emitting elements on the circuit board 91 may include multiple first light-emitting elements 915. Multiple first light-emitting elements 915 may provide multiple light sources. The multiple first light-emitting elements 915 are arranged circumferentially around the first bracket 94 to achieve an annular or circumferential light display effect, ensuring that light is evenly distributed around the knob 80, thereby providing a variety of status indications for the functions controlled by the pulsator washing machine knob 80.
[0312] In some embodiments, as shown in FIG57 , taking the first bracket 94 as an example, the diameter of the first light outlet 946 can gradually increase from the end of the first light outlet 946 closer to the circuit board 91 to the end of the first light outlet 946 farther from the circuit board 91. By increasing the diameter of the light outlet, the propagation direction of light can be effectively controlled, and the light can be focused at the first light outlet 946 , and after focusing, the light can be appropriately diverged, achieving a good light guiding effect. This not only effectively reduces the brightness loss of light, but also ensures the brightness and uniformity of the light, thereby improving the visual effect of the entire control panel 70.
[0313] In some embodiments, as shown in FIG57 , the light outlet may have a small-diameter end. The small-diameter end is the end of the light outlet facing the circuit board 91. The light-emitting element may be positioned within the small-diameter end of the light outlet to ensure an appropriate angle of incidence for the light. The light outlet may also have a large-diameter end. The large-diameter end is the end of the light outlet facing away from the circuit board 91. The cross-sectional area of the large-diameter end is larger than that of the small-diameter end.
[0314] In some embodiments, the light outlet can be provided with a flat inner wall. It is understood that when light is incident from one medium (such as air) into another medium (such as the inner wall of the light outlet), reflection occurs. The law of reflection states that the reflected light, the incident light, and the normal are all in the same plane, and the angle of the reflected light is equal to that of the incident light. Therefore, if the inner wall of the light outlet is flat, light can be reflected regularly according to the law of reflection.
[0315] In some embodiments, the inner wall of the light outlet itself may not directly guide light, but it can affect the propagation path of light. Light emitted by the light guide located within the small-diameter end will, according to the law of reflection, be reflected multiple times on the inner wall of the light outlet. It will be focused toward the large-diameter end along the direction indicated by the arrow in Figure 36 and converge to point to a specific point or area on the large-diameter end, ultimately escaping from the large-diameter end along the diagram, achieving the light display effect.
[0316] In some embodiments, as shown in Figures 46, 56, and 58, the first bracket 94 can have multiple first partitions 947. The first partition 947 is disposed between two adjacent first light outlets 946 and is used to physically separate adjacent first light-emitting elements 915. The first partition 947 can effectively limit the propagation path of light, ensuring that the light from each first light-emitting element 915 is only displayed within its designated area.
[0317] In some embodiments, as shown in FIG58 , the thickness of the first partition 947 at the end facing away from the circuit board 91 is less than the thickness of the first partition 947 at the end facing the circuit board 91. The distance between the ends of two adjacent first partitions 947 facing the circuit board 91 is smaller, allowing light emitted by the first light-emitting elements 915 on the circuit board 91 to be focused there. A greater distance between the ends of two adjacent first partitions 947 facing away from the circuit board 91 allows the focused light to be appropriately diverged as it is emitted outward.
[0318] In some embodiments, as shown in Figures 46, 56, and 58, the first bracket 94 may further include an inner retaining wall 948 disposed around the first light outlet 946. The inner retaining wall 948 may be located on the side of the first light outlet 946 that faces the axis of the first bracket 94. The first bracket 94 may further include an outer retaining wall 949 coaxially disposed with the inner retaining wall 948. The outer retaining wall 949 is located on the side of the first light outlet 946 that faces away from the axis of the first bracket 94. The inner retaining wall 948, the outer retaining wall 949, and the first partition 947 together enclose the first light outlet 946, thereby limiting the divergence of light from the circumference of the first light-emitting element 915, ensuring that light from the first light-emitting element 915 is only displayed within the area of the first light outlet 946.
[0319] In some embodiments, as shown in Figures 46 and 56, the first partition 947 can extend radially along the first bracket 94. Since the knob 80 is circular, the first partition 947 is arranged radially around the first bracket 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. The width of the first light outlet 946 increases in the direction from the inside of the first bracket 94 to the outside of the first bracket 94. The enlarged first light outlet 946 is fan-shaped, and each first light outlet 946 is distributed around the first bracket 94, which can form a good fit with the shape of the knob 80 and improve the display effect of light.
[0320] In some embodiments, as shown in Figures 46, 47, and 53, the first bracket 94 can be provided with a fifth position-limiting portion 942. Correspondingly, the circuit board 91 can be provided with a second positioning opening 914 corresponding to the fifth position-limiting portion 942. The fifth position-limiting portion 942 extends through the second positioning opening 914 on the circuit board 91. Providing the fifth position-limiting portion 942 on the first bracket 94 can restrict the first bracket 94 from being installed on the second bracket 95 according to a predetermined position, ensuring that the first light outlet 946 on the first bracket 94 corresponds to the position of the first light-emitting element 915 on the circuit board 91.
[0321] In some embodiments, as shown in Figures 41, 53, and 54, the control panel 70 may include a third bracket 92. The bracket may include the third bracket 92. The third bracket 92 may be disposed on the side of the circuit board 91 facing away from the frame 12. The third bracket 92 provides structural support for the buttons and a foundation for the layout of the light-emitting components. The third bracket 92 may be provided with a plurality of second light outlets 921. The second light outlets 921 allow light emitted by the light-emitting components corresponding to the third bracket 92 to pass through.
[0322] In some embodiments, as shown in Figures 53 and 54, the circuit board 91 may be provided with multiple second light-emitting elements 916. The light-emitting elements on the circuit board 91 may include multiple second light-emitting elements 916. The multiple second light-emitting elements 916 can provide multiple light sources. The multiple second light-emitting elements 916 emit light through multiple second light outlets 921, thereby achieving status indication and backlighting effects for the key area.
[0323] In some embodiments, as shown in FIG. 54 , at least some of the plurality of second light exit ports 921 are arranged in an array.
[0324] For example, some of the second light outlets 921 can be arranged in a horizontal straight line. This arrangement has a neat and uniform effect, which can facilitate users to quickly identify and operate buttons belonging to the same function category, such as washing program selection, water temperature adjustment, etc., making the operation process smoother and more efficient.
[0325] For another example, some of the second light outlets 921 can be arranged vertically in a straight line. This layout can be used to distinguish different types of functional instructions, such as detergent placement and extra wash options. The vertical extension not only creates clear visual divisions, but also helps users quickly locate the desired function among many options.
[0326] In some embodiments, as shown in FIG54 , some of the second light outlets 921 may be arranged sporadically. The sporadically arranged second light outlets 921 may be used to indicate some special functions or options. For example, they may be used to mark special functions of a pulsator washing machine, such as quick wash, energy-saving mode, and silent mode. Since these functions are generally not frequently used in daily washing, presenting them in a sporadic arrangement does not interfere with the user's quick identification of commonly used functions, while providing the user with more personalized and diverse choices.
[0327] In conjunction with the above embodiment, by arranging at least some of the multiple second light outlets 921 in an array, this design achieves a backlighting effect and consistent status indication in the key area. This array arrangement not only enhances the visual aesthetics of the control panel 70 but also improves user intuitiveness and convenience during operation. This design optimizes the light distribution path, reduces light unevenness and mutual interference, and further enhances the overall display effect.
[0328] In some embodiments, as shown in Figures 53 and 54 , the third bracket 92 may include a second partition 922. This partition 922 can physically separate adjacent second light-emitting elements 916 in the same column, preventing light from interfering with each other and thus reducing light crosstalk. By separating adjacent light-emitting elements in the same column, the partition 922 effectively restricts the light propagation path, ensuring that the light from each second light-emitting element 916 is displayed only within its designated area, thereby improving the display clarity of the key area and the accuracy of the function indication.
[0329] In some embodiments, as shown in Figures 54 and 55 , the thickness of the second partition plate 922 at the end facing away from the circuit board 91 can be smaller than the thickness of the end facing the circuit board 91. The distance between the ends of two adjacent second partition plates 922 facing the circuit board 91 is smaller, allowing light emitted by the second light-emitting elements 916 on the circuit board 91 to be focused there. A greater distance between the ends of two adjacent second partition plates 922 facing away from the circuit board 91 allows the focused light to be appropriately diverged when emitted outward.
[0330] In some embodiments, as shown in Figures 52 and 54, the device portion 73 may be provided with a light-emitting port 735. The light-emitting port 735 may correspond to each light outlet port. The shape of the light-emitting port 735 may be adapted to the shape of the corresponding light outlet port. The light-emitting port 735 allows light from the light-emitting element to pass through. The second light-emitting element 916 emits light through the light-emitting port 735. This light can be effectively transmitted to the exterior of the control panel 70, providing a clear status indication and visual effect.
[0331] It should be noted that there may be a gap between the surface of the third bracket 92 facing the device portion 73 and the device portion 73. Light emitted by the second light-emitting element 916 needs to pass through this gap to reach the inner side of the light-emitting port 735 of the device portion 73 and then diffuse outward from the device portion 73. However, when light passes through this gap, it may diffuse outward from the gap, resulting in light crosstalk.
[0332] In some embodiments, as shown in FIG54 , the third bracket 92 may be provided with an extension piece 923. The first end of the extension piece 923 is connected to the second partition plate 922, and the second end of the extension piece 923 extends away from the circuit board 91. The extension piece 923 can deepen the depth of the second light outlet 921 and improve the light isolation effect. At least a portion of the extension piece 923 is located in the light-emitting port 735. The extension piece 923 can block the gap between the side of the third bracket 92 facing the device part 73 and the device part 73. When light passes through this place, it will be blocked by the extension piece 923, effectively avoiding the light leakage phenomenon.
[0333] In some embodiments, as shown in Figures 40 and 56, a light-transmitting sealant is provided in the light outlet. For example, the light-transmitting sealant can be a sealant. By performing a glue filling process on the light outlet, on the one hand, the light outlet can be sealed by the light-transmitting sealant, effectively preventing dust, moisture and other impurities from entering the light outlet, 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, thereby improving the installation stability of the bracket to avoid loosening or displacement during frequent operation. In addition, the light-transmitting sealant can also ensure the effective passage of light, thereby improving the clarity and contrast of the display effect.
[0334] In some embodiments, as shown in Figures 44 and 56, a second snap-in interface 924 can be provided on the circumference of the third bracket 92. Correspondingly, a sixth snap-in portion 955 can be provided on the outer wall of the second bracket 95 at a position corresponding to the second snap-in interface 924. The sixth snap-in portion 955 corresponds to the second snap-in interface 924 and snaps into the second snap-in interface 924. By configuring the third bracket 92 and the second bracket 95 as a snap-in connection, a stable and effective connection can be achieved. Furthermore, the snap-in connection provides a simplified assembly method, reduces reliance on traditional fasteners, and improves assembly efficiency and connection stability. When installing the third bracket 92 on the second bracket 95, the third bracket 92 needs to be pressed toward the second bracket 95 so that the sixth snap-in portion 955 snaps into the second snap-in interface 924. However, during the pressing process, the third bracket 92 and the second bracket 95 may shift relative to each other, resulting in a connection offset.
[0335] In some embodiments, as shown in Figures 44, 55, and 56, a positioning groove 925 may be provided on a side of the third bracket 92 facing the second bracket 95. The positioning groove 925 is used to plug and connect with the second bracket 95 to facilitate positioning when the third bracket 92 and the second bracket 95 are assembled, thereby improving the connection accuracy between the third bracket 92 and the second bracket 95 and preventing connection deviation.
[0336] For example, the positioning groove 925 can be a gap between a reinforcing rib provided on the side of the third bracket 92 facing the second bracket 95 and a side panel of the third bracket 92. The width of the positioning groove 925 can be slightly larger than the side panel of the second bracket 95. When the third bracket 92 is pressed against the second bracket 95, the side panel of the second bracket 95 can be inserted into the positioning groove 925.
[0337] It should be noted that, in some embodiments, the first bracket 94, the third bracket 92 and the circuit board 91 are all installed on the second bracket 95, with a high degree of integration, which can realize modular assembly and installation, help improve production efficiency, and facilitate subsequent maintenance and replacement.
[0338] In the related art, a pulsator washing machine includes a housing, a frame, and a control panel. The housing is the main structure of the pulsator washing machine, used to accommodate or support its various components. The control panel is mounted on the top of the housing, and clothes are dropped into the pulsator washing machine through the inlet on the frame. The control panel is mounted on the top of the frame and is equipped with knobs, a display panel, and other components to transmit and execute various operating instructions for the pulsator washing machine. However, after the control panel is connected to the frame on one side via a snap, the assembler needs to hold the frame by hand to complete the screw installation on the other side. This results in a complicated assembly process of the control panel and the frame, and low assembly efficiency.
[0339] To solve the above problems, as shown in Figures 59, 60 and 61, a pulsator washing machine according to some embodiments of the present disclosure is disclosed. The pulsator washing machine may include a housing 11, a frame 12, a drum assembly and a control panel 70. The frame 12 is arranged at the top of the housing 11. The drum assembly is arranged in the housing 11, and the drum assembly has a washing chamber 20. The barrel mouth of the drum assembly is connected to the washing chamber 20 and faces the delivery port 121. The control panel 70 is mounted on the frame 12. The control panel 70 includes a front enclosure 71 and a rear enclosure 72. At least one of the front enclosure 71 and the rear enclosure 72 is provided with a fixed structure.
[0340] For example, the slots in the fixing structure engage with the snaps on the frame 12 to restrict upward movement of the control panel 70 in the width and height directions. Another example is that the stoppers in the fixing structure abut against the plug-in sections to restrict downward movement of the control panel 70 in the depth and height directions. By engaging the slots and plugging the stoppers on the control panel 70, the control panel 70 can be quickly installed on the frame 12, simplifying the assembly process and improving assembly efficiency.
[0341] 59 and 60 , the pulsator washing machine may include a housing 11. The housing 11 is the outer shell of the pulsator washing machine, and important components of the pulsator washing machine, such as a motor, a pulsator, and a drum assembly, may be disposed within the housing 11.
[0342] It should be noted that when the user stands in front of the pulsator washing machine, the perspective toward the pulsator washing machine is used as a reference. The front of the user is opposite to the front of the pulsator washing machine, and the front of the pulsator washing machine is opposite to the back of the pulsator washing machine. The left side of the user can be used to indicate the left side of the pulsator washing machine, and the right side of the user can be used to indicate the right side of the pulsator washing machine. The direction parallel to the line connecting the front and back of the pulsator washing machine is defined as the depth direction of the pulsator washing machine, the direction parallel to the line connecting the left and right sides of the pulsator washing machine is defined as the width direction of the pulsator washing machine, and the direction parallel to the line connecting the bottom and top of the pulsator washing machine is defined as the height direction of the pulsator washing machine.
[0343] In some embodiments, as shown in Figures 59 and 60 , the pulsator washing machine may include a control panel 70 , which is used to install control components (such as encoders, display panels, knobs, etc.) The control panel 70 may be installed on the top of the surrounding frame 12 .
[0344] In some embodiments, as shown in Figures 61 and 62, the control panel 70 may include a rear enclosure 72. The rear enclosure 72 may be provided on the enclosure frame 12. The rear enclosure 72 may be located at the rear side of the control panel 70, near the back of the box 11. The rear enclosure 72 may provide protection and support for the control components.
[0345] In some embodiments, as shown in Figures 61 and 62, the control panel 70 may include a front enclosure 71. The front enclosure 71 may be provided on a side of the rear enclosure 72 facing away from the back of the box 11. The front enclosure 71 may provide protection and support for the control device.
[0346] In some embodiments, as shown in Figures 60 and 61 , the control panel 70 may include a device portion 73. One end of the device portion 73 may be connected to the rear enclosure portion 72 and the other end to the front enclosure portion 71. Device portion 73 may be mounted with control components, such as a circuit board and knobs. Device portion 73 may be tilted to facilitate user operation and information viewing.
[0347] In some embodiments, as shown in FIG. 62 and FIG. 63 , a slot portion 122 may be provided on the surrounding frame 12 , and the control panel 70 may be mounted on the surrounding frame 12 through the slot portion 122 .
[0348] In some embodiments, as shown in FIG. 62 and FIG. 63 , a limiting portion 123 may be provided on the surrounding frame 12 , and the control panel 70 may be mounted on the surrounding frame 12 through the limiting portion 123 .
[0349] In some embodiments, as shown in Figures 62 and 63 , the front enclosure 71 may be provided with a fixing structure 75 (e.g., a buckle, a groove, a mounting hole, or other fixing structure). The front enclosure 71 may be connected to the slot 122 or the stopper 123 via the fixing structure 75 to mount the control panel 70 on the enclosure frame 12 .
[0350] In some embodiments, the rear enclosure portion 72 may be provided with a fixing structure 75 , and the rear enclosure portion 72 may be connected to the slot portion 122 and the limiting portion 123 through the fixing structure 75 , so as to install the control panel 70 on the enclosure frame 12 .
[0351] In some embodiments, as shown in Figures 62 and 63, both the front enclosure 71 and the rear enclosure 72 may be provided with a fixing structure 75. The front enclosure 71 and the rear enclosure 72 may be connected to the slot 122 or the stopper 123 via the fixing structure 75, thereby mounting the control panel 70 on the enclosure frame 12.
[0352] In some embodiments, as shown in Figures 62 and 63, the fixing structure 75 may include a snap portion 751, which is snapped into the slot portion 122 on the frame 12 to limit the relative movement of the control panel 70 and the frame 12.
[0353] In some embodiments, as shown in FIG. 62 and FIG. 63 , the fixing structure 75 may include an inserting portion 752 , which abuts against the limiting portion 123 to limit the relative movement of the control panel 70 and the surrounding frame 12 .
[0354] In some embodiments, as shown in Figure 63, the latch portion 751 extends toward the inside of the pulsator washing machine to form a protrusion with a latching function. The latch portion 751 can be provided with an upwardly facing abutment surface 7510. The latching groove portion 122 can be engaged with the latch portion 751 via the abutment surface 7510. This arrangement restricts the control panel 70 from moving upward in the height direction.
[0355] In some embodiments, as shown in FIG. 63 , two side surfaces of the buckle portion 751 adjacent to the abutting surface 7510 may abut against the slot portion 122 to limit movement of the control panel 70 in the width direction.
[0356] In some embodiments, as shown in Figures 63 and 65, the insertion portion 752 can be provided with an opening facing downward toward the frame 12 to form an insertion slot 753. The limiting portion 123 of the frame 12 extends upward from one end thereof, away from the frame 12, and can be inserted into the insertion slot 753. The limiting portion 123 of the frame 12 extends upward to limit downward movement of the control panel 70 in the height direction. The insertion slot 753 is inserted into the frame 12, and the side surfaces of the insertion slot 753 mate with the frame 12 to limit movement of the control panel 70 in the depth direction.
[0357] In some embodiments, as shown in Figures 63 and 65, the snap-fitting portions 751 and the plug-in portions 752 may be spaced apart along the width direction of the control panel 70 to disperse the forces acting on the snap-fitting portions 751 and the plug-in portions 752 and improve the reliability of the control panel 70.
[0358] In some embodiments, as shown in Figures 62, 63, and 65, at least one of the front and rear enclosures 71 and 72 is provided with a fixing structure 75. A snap-fit portion 751 in the fixing structure 75 can engage with the slot 122 on the enclosure 12, and a plug-in portion 752 in the fixing structure 75 can abut against the stopper 123. By engaging the snap-fit portion 751 and plugging the plug-in portion 752 of the control panel 70, the control panel 70 can be quickly installed on the enclosure 12. This arrangement simplifies the assembly process of the control panel 70 without the need for installation tools, improving assembly efficiency. This method is comparable to first inserting the front enclosure 71 and then snapping the rear enclosure 72 in place, or by appropriately adjusting the position of the rear enclosure 72 before snapping in place. After aligning the front enclosure 71 or the rear enclosure 72 with the enclosure 12, the control panel 70 can be quickly installed on the enclosure 12 by engaging the snap portion 751 and plugging the plug portion 752, without having to worry about the other side of the control panel 70. This can save time and improve the assembly efficiency of the control panel 70.
[0359] In some embodiments, as shown in Figures 62 and 63, the fixing structure 75 can be provided with multiple snap-fit portions 751 and multiple plug-in portions 752 to ensure reliable installation of the fixing structure 75. During operation of the pulsator washing machine, the control panel 70 may be subjected to forces and vibrations from multiple directions. This configuration can improve the uniformity of the forces applied to the control panel 70 and prevent deformation or loosening of the control panel 70.
[0360] In some embodiments, as shown in Figures 62 and 63, to avoid stress concentration that could damage the control panel 70, the snap-fit portions 751 and the plug-in portions 752 of the fixing structure 75 are alternately arranged along the width of the pulsator washing machine. This disperses the forces acting on the control panel 70, thereby improving the smoothness of the control panel 70 during installation. For example, along the width of the control panel 70, the first snap-fit portion 751, the first plug-in portion 752, the second snap-fit portion 751, the second plug-in portion 752, the third snap-fit portion 751, and the third plug-in portion 752 are arranged in that order.
[0361] In some embodiments, as shown in Figures 62 and 63, if the distance between the snap portions 751 and the plug portions 752 is less than 20 mm, the control panel 70 may become too rigid, making assembly difficult. Furthermore, if the distance between the snap portions 751 and the plug portions 752 is too small, the snap portions 751 and the plug portions 752 may be arranged too closely together, increasing the processing and manufacturing costs of the control panel 70.
[0362] In some embodiments, as shown in Figures 62 and 63, when the distance between the adjacent snap portion 751 and the plug portion 752 is greater than 100 mm, the area between the snap portion 751 and the plug portion 752 may bulge or dent due to lack of support, thereby reducing the aesthetics of the pulsator washing machine. In addition, if the distance between the snap portion 751 and the plug portion 752 is too large, a gap may appear at the connection between the control panel 70 and the surrounding frame 12. When water splashes onto the surrounding frame 12, the risk of water intrusion into the control panel 70 increases, thereby causing the control device to fail.
[0363] Therefore, in some embodiments, the distance between the adjacent snap portions 751 and the adjacent plug portions 752 in the fixing structure 75 can be greater than or equal to 20 mm and less than or equal to 100 mm. This can prevent problems such as difficulty in assembling the control panel 70 or dents, thereby ensuring reliable and stable installation of the control panel 70.
[0364] In some embodiments, the distance between the snap portion 751 and the plug 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 consisting of any two of them. The distance value is set according to actual needs.
[0365] In some embodiments, the control panel 70 may include multiple fixing structures 75 to improve the overall stability and vibration resistance of the control panel 70. The multiple fixing structures 75 can disperse external forces and reduce stress concentration that may cause deformation or damage to the frame 12.
[0366] In some embodiments, the plurality of fixing structures 75 may include a first fixing structure and a second fixing structure. The first fixing structure and the second fixing structure may be disposed at different positions on the control panel 70. Alternatively, the first fixing structure and the second fixing structure may be disposed as different types of fixing structures 75.
[0367] In some embodiments, as shown in Figures 63 and 65, the first fixing structure can connect one or more slots 122 and one or more limiters 123. By providing multiple structures on the frame 12 that connect to the first fixing structure of the control panel 70, the control panel 70 can be mounted on the frame 12. The first fixing structure can improve the stability of the control panel 70 when mounted on the frame 12.
[0368] In some embodiments, as shown in Figures 63 and 65, the second fixing structure can connect one or more slots 122 and one or more limiters 123. By providing multiple structures on the frame 12 that connect to the second fixing structure of the control panel 70, the control panel 70 can be mounted on the frame 12. The second fixing structure can ensure improved stability when the control panel 70 is mounted on the frame 12.
[0369] In some embodiments, as shown in Figures 63, 64, and 65, the frame 12 may be provided with a third limiting portion 1231. The limiting portion 123 on the frame 12 may include the third limiting portion 1231. The third limiting portion 1231 protrudes from the frame 12 and is close to the front fence portion 71. The third limiting portion 1231 may be a long, plate-like structure or a rib structure.
[0370] In some embodiments, the slot portion 122 on the frame 12 may include a first slot portion 1221. The frame 12 may be provided with a plurality of first slot portions 1221. The first slot portion 1221 may be made by machining a groove on the third limiting portion 1231.
[0371] In some embodiments, the third limiting portion 1231 may be reused on the surrounding frame 12. This reduces the number of components on the surrounding frame 12, reduces the size of the surrounding frame 12, and reduces the processing cost of the surrounding frame 12.
[0372] In some embodiments, as shown in Figures 63 and 65 , the front panel 71 is the primary area of user interaction and contact, requiring robustness and durability. A first securing structure is provided on the front panel 71 to ensure the stability of the control panel 70. Furthermore, the presence of the first securing structure on the front panel 71 provides initial support for other components during assembly, reducing assembly difficulty.
[0373] In some embodiments, as shown in Figures 63 and 66, the snap portion 751 in the first fixing structure can be a first snap portion 7511. The first snap portion 7511 can be located on the surface of the front enclosure 71 facing the rear enclosure 72. The first snap portion 7511 can engage with the first slot 1221. This allows for quick connection of the control panel 70, avoids the need for multiple installation tools, and improves assembly efficiency of the control panel 70.
[0374] In some embodiments, as shown in Figures 63 and 66 , the first buckle portion 7511 may be provided with an inclined surface. The inclined surface may be provided on the side facing away from the front baffle portion 71 , thereby facilitating the installation of the first buckle portion 7511 and the first slot portion 1221 and improving the assembly efficiency of the control panel 70 .
[0375] In some embodiments, as shown in Figures 63 and 66, the plug-in portion 752 in the first fixing structure may be a first plug-in portion 7521. The first plug-in portion 7521 may be located on the surface of the front enclosure portion 71 facing the rear enclosure portion 72, and the first plug-in portion 7521 may abut against the third stopper 1231. This allows for faster connection of the control panel 70, avoids the use of multiple installation tools, and improves assembly efficiency of the control panel 70.
[0376] In some embodiments, as shown in Figures 63 and 66, the first plug-in portion 7521 is formed with a plug-in slot 753 along the width direction of the control panel 70. The plug-in slot 753 allows the third limiting portion 1231 to be plugged in, which reduces the difficulty of plugging the first plug-in portion 7521 into the second slot portion 1222 and improves assembly efficiency.
[0377] In some embodiments, as shown in Figures 63 and 66, the first plug-in portion 7521 can be set on the front enclosure portion 71 and extend toward the top to the device portion 73. This can enhance the stability of the angle between the device portion 73 and the front enclosure portion 71 and improve the stability of the connection between the device portion 73 and the front enclosure portion 71.
[0378] In some embodiments, as shown in Figures 67 and 68, the slot portion 122 on the frame 12 may include a second slot portion 1222. The frame 12 may be provided with multiple second slot portions 1222. The second slot portions 1222 are made by machining grooves on the rear side of the frame 12, which has a high degree of integration.
[0379] In some embodiments, as shown in Figures 67 and 68, the retaining portion on the frame 12 may include a fourth retaining portion 1232. The frame 12 may be provided with multiple fourth retaining portions 1232. The fourth retaining portions 1232 may protrude from the frame 12 and extend upward for a certain distance to ensure connection reliability. The fourth retaining portions 1232 may be in the form of an elongated plate or a rib structure.
[0380] In some embodiments, as shown in FIG. 69 , a second fixing structure may be provided on the rear enclosure portion 72 to ensure the stability of the control panel 70 .
[0381] In some embodiments, as shown in Figures 68 and 69, the latch portion 751 in the second fixing structure may be a second latch portion 7512. The second latch portion 7512 may be located on the surface of the rear enclosure 72 facing the front enclosure 71. The second latch portion 7512 engages with the second latching groove 1222. This allows for faster connection of the control panel 70, avoids the need for multiple installation tools, and improves assembly efficiency of the control panel 70.
[0382] In some embodiments, as shown in Figures 68 and 69, the second snap-fit portion 7512 can be provided with an inclined surface, and the inclined surface can be provided on the side thereof facing away from the front enclosure portion 71, so as to facilitate the installation of the second snap-fit portion 7512 and the second slot portion 1222 and improve the assembly efficiency of the control panel 70.
[0383] In some embodiments, as shown in Figures 68 and 69, the plug-in portion 752 in the second fixing structure may be a second plug-in portion 7522. The second plug-in portion 7522 may be located on the surface of the rear enclosure portion 72 facing the front enclosure portion 71, and the second plug-in portion 7522 abuts against the fourth stopper 1232. This allows for faster connection of the control panel 70, avoids the need for multiple installation tools, and improves assembly efficiency of the control panel 70.
[0384] In some embodiments, as shown in Figures 68 and 69, the second plug-in portion 7522 may protrude from the rear enclosure portion 72 and be formed with a downwardly opening plug-in slot 753. The second latching slot 1222 protrudes from the enclosure frame 12, which can improve the reliability of the plug-in connection between the second plug-in portion 7522 and the fourth limiting portion 1232 and facilitate installation.
[0385] In some embodiments, as shown in Figures 68 and 69, the second fixing structure may further include a fastener. The rear enclosure portion 72 may be provided with a mounting hole 7523, and the fastener passes through the mounting hole 7523 of the rear enclosure portion 72 and is connected to the threaded hole of the enclosure frame 12. In this way, the rear enclosure portion 72 can be connected to the threaded hole of the enclosure frame 12 through the mounting hole 7523. The fastener can further strengthen the connection strength between the control panel 70 and the enclosure frame 12. This can prevent cracks from appearing in the connection between the control panel 70 and the enclosure frame 12 when the pulsator washing machine vibrates strongly. For example, the fastener can be a screw or a bolt. Specifically, the fastener can be a pan head screw or a countersunk screw to improve the aesthetics of the pulsator washing machine.
[0386] In some embodiments, as shown in FIG69 , the second buckle portions 7512 , the second plug-in portions 7522 , and the fasteners may be alternately arranged along the width direction of the pulsator washing machine to avoid stress concentration that may damage the control panel 70 .
[0387] In some embodiments, as shown in FIG69 , if the distance between the second latch portion 7512, the second plug portion 7522, and the mounting hole 7523 is less than 20 mm, the control panel 70 may become too rigid, making assembly difficult. Furthermore, if the distance between the second latch portion 7512, the second plug portion 7522, and the fastener is too small, the second latch portion 7512, the second plug portion 7522, and the fastener may be arranged too densely, increasing the processing and manufacturing costs of the control panel 70.
[0388] In some embodiments, as shown in FIG69 , if the distance between the second latch portion 7512, the second plug portion 7522, and the mounting hole 7523 is greater than 100 mm, the area between the second latch portion 7512, the second plug portion 7522, and the fastener may bulge or dent due to lack of support, thereby reducing the aesthetics of the pulsator washing machine. Furthermore, if the distance between the second latch portion 7512, the second plug portion 7522, and the mounting hole 7523 is too large, a gap may appear at the connection between the control panel 70 and the frame 12. This increases the risk of water intrusion when water splashes onto the frame 12, thereby causing the control device to fail.
[0389] Therefore, the distance between the second latch portion 7512, the second plug portion 7522, and the mounting hole 7523 is greater than or equal to 20 mm and less than or equal to 100 mm.
