[0055] See also Figures 1 to 7 As shown, in some embodiments, the door cover 3 is provided at the clothing loading port 11, and one end of the door cover 3 is hinged to the housing 1 and is hinged to the surrounding frame 13 on the housing 1, so as to be able to open or close the clothing loading port 11. When the door cover 3 rotates, the clothing loading port 11 can be opened to facilitate putting clothing into the clothing processing chamber or taking clothing out of the clothing processing chamber. When the door cover 3 rotates in the opposite direction, the clothing loading port 11 can be closed.

[0056] Specifically, when washing clothes, the flip door cover 3 can be opened so that the end of the door cover 3 away from the hinge axis is separated from the clothes loading port 11 of the surrounding frame 13, so that the door cover 3 is opened to expose the inner drum 22, and the clothes can be placed in the clothes processing chamber for washing. When it is necessary to take out the clothes, the door cover 3 is flipped again to expose the inner drum 22, and then the clothes can be taken out.

[0057] See also Figures 3 to 5 As shown, in some embodiments, the hinge axis of the door cover 3 and the surrounding frame 13 is arranged at the rear edge of the clothing loading port 11, that is, the rear end of the door cover 3 is hinged to the surrounding frame 13, so that when washing clothes, the front end of the flip door cover 3 can be opened and turned to make the front end of the door cover 3 away from the surrounding frame 13, so that the door cover 3 opens the clothing loading port 11, and the clothes can be placed in the clothing processing chamber for washing. When it is necessary to take out the clothes, the front end of the door cover 3 is flipped again to expose the inner drum 22, and then the clothes can be taken out.

[0058] See also Figure 4 and Figure 5As shown, in some embodiments, the rear end of the door cover 3 is provided with a clamping portion 31, which protrudes backward from the door cover 3. The rear side of the surrounding frame 13 is provided with a clamping interface 131, and the clamping portion 31 can be clamped at the clamping interface 131, and when the door cover 3 opens or closes the clothing loading port 11, the clamping portion 31 can also open and close with the door cover 3 at the clamping interface 131.

[0059] See also Figures 3 to 5 As shown, in some embodiments, the door cover 3 and the clothing loading port 11 have the same shape and contour, so that the door cover 3 can fully seal the clothing loading port 11. Specifically, the door cover 3 and the clothing loading port 11 are both rectangular.

[0060] It should be noted that, in some other embodiments, the door cover 3 and the clothing loading port 11 may also be in other shapes.

[0061] See also Figure 5 As shown, in some embodiments, a mounting groove 132 is provided at the top of the frame 13, and the mounting groove 132 is provided above the clothing loading port 11, and the cross-sectional area of ​​the mounting groove 132 is larger than the cross-sectional area of ​​the clothing loading port 11, and the cross-sectional area of ​​the mounting groove 132 is also larger than the cross-sectional area of ​​the door cover 3, so that the door cover 3 can be completely installed in the mounting groove 132 and can completely cover the clothing loading port 11.

[0062] Usually, the door cover 3 is located above the surrounding frame 13. When closing the door cover 3, under the action of gravity, the door cover 3 will quickly cover the clothing inlet 11 of the surrounding frame 13.

The damper 4 is used to provide a damping force for the door cover 3, so that when the door cover 3 covers the clothing inlet 11, the damping force can slow down the closing speed of the door cover 3, thereby preventing the door cover 3 from pinching the hand.

[0065] It should be noted that, in some other embodiments, the damper 4 may also be disposed on the box 12 or at other locations.

[0067] See also Figures 8 to 12 As shown, in some embodiments, a coupling portion 32 is convexly provided on the door cover 3, and the coupling portion 32 is convexly provided on the bottom surface of the door cover 3 and is provided at the rear edge of the clothing loading port 11. The damper 4 is also provided at the rear edge of the clothing loading port 11, so that the coupling portion 32 can correspond to the damper 4. The coupling portion 32 is used to abut against the damper 4 when the door cover 3 covers the clothing loading port 11, so that the damper 4 provides a reverse damping force to the coupling portion 32, and then the damping force received by the coupling portion 32 slows down the closing speed of the door cover 3.

[0068] It should be noted that the coupling portion 32 and the damper 4 may also be arranged at other side edges of the clothing loading port 11 .

[0069] In some embodiments, when the coupling part 32 covers the clothing inlet 11 of the door cover 3, the coupler 32 needs to extend into the accommodating groove 133 and abut against the damper 4, so that the damper 4 provides a reverse damping force to the coupling part 32, and then the damping force received by the coupling part 32 slows down the closing speed of the door cover 3.

[0070] In some embodiments, the coupling portion 32 is integrally formed with the door cover 3 , and the coupling portion 32 can move along with the movement of the door cover 3 .

[0071] It should be noted that in some other embodiments, the coupling portion 32 and the door cover 3 may also be provided separately.

[0072] In some embodiments, the coupling portion 32 extends downward from the bottom surface of the door cover 3, and then bends and extends backward, so that the coupling portion 32 has a structure with the bottom end bent backward, and the rear end of the coupling portion 32 is used to abut against the damper 4, so that when the door cover 3 covers the clothing inlet 11, the rear end of the coupling portion 32 can push the damper 4 to generate an opposite damping force, thereby slowing down the closing speed of the door cover 3.

[0073] In some embodiments, the coupling portion 32 is disposed on one side of the hinge axis between the door cover 3 and the surrounding frame 13 . The coupling portion 32 is extended in an arc shape and is arranged around the hinge axis between the door cover 3 and the surrounding frame 13 .

[0074] In some embodiments, two coupling parts 32 are provided, and the two coupling parts 32 are respectively provided on opposite sides of the connecting shaft. A plurality of dampers 4 are also provided, and the plurality of dampers 4 are respectively provided on both sides of the surrounding frame 13, and the coupling parts 32 correspond to the dampers 4 one by one. The two coupling parts 32 can jointly provide opposite damping forces for the door cover 3, and the two coupling parts 32 are provided on opposite sides of the connecting shaft, thereby ensuring that the door cover 3 can remain stable during the closing process.

[0075] It should be understood that there may be three or more coupling parts 32 and dampers 4 .

[0076] Fig.13 yes Figure 8 Schematic diagram of the structure of the middle damper 4. Fig.14 yes Fig.13 sectional view of . Fig.15 yes Fig.14 Cross-sectional view in another state.

[0077] See also Figures 13 to 15 As shown, in some embodiments, the damper 4 includes a housing 41 and a piston rod 42. The housing 41 is fixedly arranged in the surrounding frame 13, one end of the piston rod 42 is movably inserted in the housing 41, and the other end of the piston rod 42 extends out and extends toward the coupling portion 32.

[0078] Specifically, when the door cover 3 closes the clothing delivery opening 11, the coupling part 32 can abut against the end of the piston rod 42 extending out of the housing 41, and push the piston rod 42 to move into the housing 41, and generate a damping force opposite to the coupling part 32 through the piston rod 42. Since the damper 4 can be in a damping state when the door cover 3 closes the clothing delivery opening 11, when the damper 4 is in the damping state, the piston rod 42 can have an upward damping force on the door cover 3, so that the door cover 3 can slow down the falling speed during the falling process, thereby preventing the hand from being pinched and the user from being injured. At the same time, the damping force is generated by the mutual abutment between the coupling part 32 and the piston rod 42, so that the internal structure of the damper 4 is simple and the space occupied by the damper 4 can be reduced.

[0079] In some embodiments, the damper 4 is arranged to extend horizontally forward and backward, and the piston rod 42 is provided at the front end of the shell 41, so that when the door cover 3 closes the clothing inlet 11, the rear end of the coupling part 32 can be against the front end of the piston rod 42 and push the piston rod 42 to move backward.

[0080] It should be noted that in some other embodiments, the damper 4 may also be arranged at an angle, which is not limited here.

[0081] See also Figures 9 to 12As shown, in some embodiments, the rear end of the coupling part 32 is provided with an abutting wall 321, and the peripheral edge of the front end surface of the piston rod 42 is provided with a rounded corner portion 421, and the rounded corner portion 421 smoothly transitions with the front end surface of the piston rod 42. When the door cover 3 covers the clothing inlet 11, when the rear end of the coupling part 32 just abuts against the front end of the piston rod 42, the abutting wall 321 abuts against the rounded corner portion 421, and the abutting wall 321 is located on a tangent line of the rounded corner portion 421.

[0082] In some embodiments, when the door cover 3 covers the clothing loading port 11, the abutting wall 321 can move along the front end surface of the piston rod 42, and when the door cover 3 completely covers the clothing loading port 11, the abutting wall 321 abuts against the front end surface of the piston rod 42. Specifically, when the door cover 3 completely covers the clothing loading port 11, there is a gap between the abutting wall 321 and the upper end of the rounded corner portion 421 and between the abutting wall 321 and the lower end of the rounded corner portion 421.

[0083] In some embodiments, when the door cover 3 completely covers the clothing loading port 11, the distance between the abutment point between the abutment wall 321 and the piston rod 42 and the axis of the piston rod 42 is less than 15 mm, so as to ensure that the damper 4 can be evenly stressed.

[0084] See also Figures 13 to 15 As shown, in some embodiments, a damping chamber 411 is provided inside the shell 41, and the extension direction of the damping chamber 411 is the same as the moving direction of the piston rod 42. One end of the piston rod 42 can be movably inserted in the damping chamber 411, and then the damping chamber 411 is compressed inwardly by the piston rod 42 to generate an opposite damping force.

[0085] In some embodiments, a accommodating chamber 422 is provided inside the piston rod 42, and an extension direction of the accommodating chamber 422 is also provided with an opening at the end of the piston rod 42 extending into the shell 41, and the accommodating chamber 422 is connected to the damping chamber 41 through the opening.

[0086] In some embodiments, the damper 4 further includes a first spring 43, a spring seat 44 and a fixing rod 45. The first spring 43 is disposed in the accommodating chamber 422, and one end of the first spring 43 abuts against the bottom of the accommodating chamber 422; the spring seat 44 is slidably disposed in the accommodating chamber 422 and abuts against the other end of the first spring 43. The fixing rod 45 is disposed in the damping chamber 411, and one end of the fixing rod 45 extends into the accommodating chamber 422 and is connected to the spring seat 44, and the other end of the fixing rod 45 abuts against the inner wall of the damping chamber 411, so that when the door cover 3 covers the clothing delivery port 11, the coupling part 32 abuts against the piston rod 42 and moves toward the damping chamber 411, thereby squeezing one end of the first spring 43 away from the spring seat 44, so that the first spring 43 is compressed in the accommodating chamber 422, and then the elasticity of the first spring 43 can produce a damping effect, thereby achieving a slow-down effect of the door cover 3.

[0087] In some embodiments, the damping chamber 411 further includes an end cap 46, which is disposed at the front end of the housing 41 and is used to cover the damping chamber 411. One end of the piston rod 42 passes through the end cap 46 and then extends into the housing 41, and the piston rod 42 can slide relative to the end cap 46.

[0088] In some embodiments, the damper 4 further includes a sealing seat 47, which is disposed in the damping chamber 411 and can slide sealingly along the inner wall of the damping chamber 411. One end of the sealing seat 47 is fixedly connected to the piston rod 42, so that the sealing seat 47 can slide in the damping chamber 411 along with the piston rod 42.

[0089] In some embodiments, the damper 4 further includes a piston 48, which is disposed in the damping chamber 411 and at an end of the sealing seat 47 away from the piston rod 42. The sealing seat 47 is fixedly connected to the piston rod 42 so that the piston 48 can slide in the damping chamber 411 along with the sealing seat 47.

[0090] See also Figures 13 to 15 As shown, in some embodiments, the damper 4 further includes a damping medium, which is disposed in the damping chamber 411 and in the damping chamber 411 on the side of the piston 48 away from the piston rod 42. When the door cover 3 closes the clothing inlet 11, the coupling portion 32 pushes the piston rod 42 to drive the sealing seat 47 and the piston 48 to compress the damping chamber 411, so that the damping medium is compressed in the damping chamber 411, thereby providing a damping force for the piston rod 42, thereby achieving a slow-down effect of the door cover 3.

[0091] In some embodiments, a second spring is further provided in the damper 4, and the second spring is provided in the damping chamber 411 and on the side of the piston 48 away from the piston rod 42. The second spring is arranged to extend along the extension direction of the damping chamber 411, one end of the second spring abuts against the piston 48, and the other end of the second spring abuts against the bottom inner wall of the damping chamber 411, so that when the piston rod 42 compresses the damping chamber 411 backward, the second spring can be compressed in the damping chamber 411 to provide an opposite damping force for the piston rod 42, thereby achieving a slow-down effect of the door cover 3.

[0092] It should be noted that, in some other embodiments, only one of the damping medium and the second spring may be provided, or both may be provided.

[0093] It can be seen from the above technical solutions that the embodiments of the utility model have at least the following advantages and positive effects:

[0094] The utility model provides a pulsator washing machine, which covers the door cover 3 at the clothing inlet 11 of the casing 1, and one end of the door cover 3 is hinged to the casing 1, so that the door cover 3 can rotate relative to the casing 1, thereby opening or closing the clothing inlet 11. The door cover 3 is provided with a coupling part 32, and the damper 4 is provided with a piston rod 42 and a shell 41. When the door cover 3 covers the clothing inlet 11, the coupling part 32 can abut against one end of the piston rod 42 extending out of the shell 41, and push the piston rod 42 to move toward the shell 41, so that the piston rod 42 can provide an opposite damping force to the coupling part 32, thereby achieving a slow-down effect of the door cover 3. Through the mutual cooperation of the piston rod 42 and the coupling part 32, the occupied space of the damper 4 can be effectively reduced, thereby improving the appearance effect.
