With the improvement of living standards, washing machines have become common in millions of households, providing convenience to people's lives.

[0003] Existing pulsator washing machines have a clothes inlet for loading clothes, with a hinged top cover that can open or close the inlet. The top cover typically houses a damper, which usually consists of a stator and a rotor that engages with the stator's damping mechanism. During assembly, the damper is placed into a mounting slot on the top cover, and one end of the rotor is fixedly connected to the washing machine body. For example, the damper may include a assisted damper and a non-assisted damper. The mounting slot has mounting holes, and the stator of the assisted damper has mounting holes that are fixedly connected to these holes. Because the assisted and non-assisted dampers are different types of dampers, the mounting holes in the mounting slot can only accommodate the assisted damper.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0031] like Figure 1-4 As shown, the present invention provides a top cover structure, including a top cover and a damper 2. The rotating side of the top cover is provided with a mounting groove 11. The damper 2 is fixed in the mounting groove 11 by a positioning structure 3. The positioning structure 3 includes a snap-fit ​​groove 311 for the non-rotating end of the damper 2 to be snapped into and a mounting hole 3151 fixedly connected to the inner wall of the mounting groove 11.

[0032] In the embodiments of the present invention, by using the snap-fit ​​groove 311 of the positioning structure 3 to snap the non-rotating end of the damper 2 and using the mounting hole 3151 of the positioning structure 3 to fix the non-rotating end of the damper 2 to the inner wall of the mounting groove 11, the mounting groove 11 can be used to install different models of dampers 2 and the damper 2 can be installed flexibly, thereby improving the assembly efficiency between the damper 2 and the top cover.

[0033] When in use, first insert the non-rotating end of the damper 2 into the snap-fit ​​groove 311, and then fix the positioning structure 3 with the non-rotating end of the damper 2 snapped into the mounting groove 11 through the mounting hole 3151, so as to provide the necessary damping for the washing machine lid to flip.

[0034] The top of the pulsator washing machine has a clothes inlet, and a top cover is hinged to the clothes inlet. The top cover flips on the washing machine to open or close the clothes inlet. A damper 2 is located on the rotating side of the top cover. By setting the damper 2 on the top cover, the top cover can be prevented from falling down quickly, and the top cover can be closed smoothly, continuously and evenly. At the same time, by setting a positioning structure 3 in the mounting groove 11 for the installation of the damper 2, the installation of the damper 2 is simple, so that there is no need to manipulate the connection between the damper 2 and the mounting groove 11 during installation. This makes the installation of the damper 2 more flexible and easy to operate.

[0035] The damper 2 has a columnar structure and includes a housing and a damping shaft inserted inside the housing. The housing is the stator part of the damper 2, and the damping shaft is the rotor part of the damper 2. The damping shaft rotates relative to the housing and is used to connect to the rotating shaft of the upper cover 1. The damping shaft extends outward from one end of the housing and is the rotating end of the damper 2. The non-rotating end is the end of the damper 2 opposite to the rotating end. The extending direction of the damping shaft is parallel to the extending direction of the mounting groove 11 and the rotating side of the upper cover 1. The mounting groove 11 has a shaft hole for the damping shaft to pass through. Furthermore, the mounting groove 11 has a mounting rib perpendicular to the extending direction of the mounting groove 11, and the mounting rib has a shaft hole for the damping shaft to pass through.

[0036] The rotating side of the top cover is provided with two mounting slots 11. The two mounting slots 11 are symmetrical about the center of the top cover, and their openings are both facing the fastening side of the top cover 1. Each mounting slot 11 is provided with a damper 2. The two dampers 2 are symmetrical about the center of the top cover 1. The two dampers 2 are the first damper and the second damper, respectively. The damping axis of the first damper and the damping axis of the second damper extend in opposite directions away from the center of the top cover 1.

[0037] It should be noted that the vertical, horizontal, and front-back directions of the latching groove 311 described below are all relative to the latching groove 311 when the top cover is in the open state. When the top cover is in the open state, the top cover is in a vertical state.

[0038] In an embodiment of the present invention, the positioning structure 3 includes a positioning body 31, which is a square block structure. One side of the positioning body 31 is recessed to form a snap-fit ​​groove 311 with the groove opening facing the non-rotating end of the damper 2. The inner wall of the snap-fit ​​groove 311 abuts against the outer periphery of the non-rotating end of the damper 2.

[0039] In the embodiments of the present invention, the positioning body 31 is a square block structure. Specifically, the positioning body 31 has a front side wall and a rear side wall in the front-back direction of the snap-fit ​​groove 1121, a left side wall and a right side wall in the left-right direction of the snap-fit ​​groove 1121, and a top wall and a bottom wall in the up-down direction of the snap-fit ​​groove 1121. The snap-fit ​​groove is located at the front side wall of the positioning body 31. The wall surface of the front side wall of the positioning body 31 is a plane, and the wall surface of the front side wall of the positioning body 31 is recessed to form the snap-fit ​​groove.

[0040] The non-rotating end of the damper 2 is adapted to the shape of the snap-fit ​​groove 311, so that each side wall of the outer periphery of the damper 2 is respectively attached to and abuts against each groove wall in the corresponding snap-fit ​​groove 311, so that the non-rotating end of the damper 2 is snapped into the snap-fit ​​groove 311, and the non-rotating end of the damper 2 is fixed on the positioning body 31.

[0041] Specifically, the damper 2 has a columnar structure. The damper 2 is divided into a first damping section 21 and a second damping section 22 located at the non-rotating end of the damper 2 in the front-back direction of the locking groove 311. The radial dimension of the first damping section 21 is larger than that of the second damping section 22. The second damping section 22 is inserted into the locking groove 311. The end wall of the first damping section 21 abuts against the positioning body 31 on the outer periphery of the locking groove 311.

[0042] The damper 2 includes a first damping section 21, a second damping section 22, and a damping shaft portion exposed outside the housing. The first damping section 21 is located between the damping shaft portion and the second damping section 22, which is equivalent to the housing being divided into the first damping section 21 and the second damping section 22. The second damping section 22 is square columnar, and the first damping section 21 is cylindrical. The maximum radial dimension of the second damping section 22 is smaller than the maximum radial dimension of the first damping section 21, so that after the second damping section 22 is inserted into the snap-fit ​​groove 311, the end wall of the first damping section 21 can abut against the positioning body 31 on the outer periphery of the snap-fit ​​groove 311, further enhancing the assembly strength between the damper 2 and the positioning body 31.

[0043] In an embodiment of the present invention, the positioning body 31 is hollow to form a cavity 312. The side walls of the cavity 312 located on the left and right sides of the snap-fit ​​groove 311 are respectively provided with openings 3123. Multiple reinforcing ribs are provided in the cavity 312 and intersectingly arranged. The outer wall of the snap-fit ​​groove 311 is connected to the reinforcing ribs.

[0044] In an embodiment of the present invention, a plurality of reinforcing ribs are provided inside the cavity 312, and the plurality of reinforcing ribs make the cavity 312 hollow, and the provision of reinforcing ribs can increase the structural strength of the positioning body 31.

[0045] The outer wall of the snap-fit ​​groove 311 is connected to the reinforcing rib. The reinforcing rib can strengthen and support the snap-fit ​​groove 311, enhance the load-bearing capacity of the snap-fit ​​groove 311, and enable the snap-fit ​​groove 311 to snap onto dampers 2 with larger weight and size.

[0046] Specifically, the snap-fit ​​groove 311 is square, and the cavity 312 is provided with a first reinforcing rib 313 and a second reinforcing rib 314, which are respectively square plate-shaped structures. The first reinforcing rib 313 extends in the front-back direction of the snap-fit ​​groove 311, and the second reinforcing rib 314 extends in the vertical direction of the snap-fit ​​groove 311. The first reinforcing rib 313 is provided with a square notch 3131, and the snap-fit ​​groove 311 is embedded in the square notch 3131. The bottom wall of the snap-fit ​​groove 311 and the left and right side walls of the groove are respectively attached and connected to the side walls of the corresponding square notch 3131.

[0047] The square notch 3131 positions the snap-fit ​​groove 311, increases the assembly strength between the snap-fit ​​groove 311 and the first reinforcing rib 313, and improves the stability of the snap-fit ​​groove.

[0048] The bottom wall and left and right side walls of the snap-fit ​​groove 311 are respectively fitted and connected to the side wall of the corresponding square notch 3131, so that the snap-fit ​​groove 311 can be connected to the first reinforcing rib 313 in all directions, thereby improving the strength of the snap-fit ​​groove 313 in a more comprehensive way.

[0049] Preferably, the middle part of the first reinforcing rib 313 intersects with the middle part of the second reinforcing rib 314. The first reinforcing rib 313 and the second reinforcing rib 314 divide the interior of the cavity 312 into several independent sub-cavities 312. The snap-fit ​​groove 311 is provided in the middle of the side wall of the cavity 312. The snap-fit ​​groove 311 has an upper part 3111 and a lower part 3112 located at the upper and lower parts of the notch, respectively. The upper part 3111 and the lower part 3112 extend into the two sub-cavities 312 distributed in the vertical direction of the snap-fit ​​groove 311, and are symmetrically arranged with the square notch 3131 as the center.

[0050] The first reinforcing rib 313 and the second reinforcing rib 314 extend in different directions within the cavity 312, resulting in multi-dimensional strength to the positioning body 31.

[0051] The first reinforcing rib 313 and the second reinforcing rib 314 are intersected to divide the interior of the cavity 312 into four identical sub-cavities. The upper part 3111 of the snap-fit ​​groove 311 extends into the upper sub-cavity 3121, and the lower part 3112 of the snap-fit ​​groove 311 extends into the lower sub-cavity 3122. This allows the first reinforcing rib 313 to evenly distribute its strength within the snap-fit ​​groove 313, and the damper 2's abutment force borne by the snap-fit ​​groove 313 to be evenly distributed within the snap-fit ​​groove 313.

[0052] It should be noted that the positioning body is provided with two locking slots, which are located on opposite sides of the positioning body, so that one locking slot is the main locking slot and the other locking slot is the auxiliary locking slot. When the main locking slot has a problem, the auxiliary locking slot can be used to lock the non-rotating end of the damper.

[0053] In an embodiment of the present invention, an upper rib 315 is provided on the outer wall of the cavity 312 located at the top of the snap-fit ​​groove 311. The upper rib 315 is a square plate structure. The upper rib 315 extends in the front-back direction of the snap-fit ​​groove 311. The mounting hole 3151 is provided on the upper rib 315 and passes through the rib in the left-right direction of the snap-fit ​​groove 311.

[0054] In specific embodiments of the present invention, the side wall of the mounting groove 11 is provided with a cylindrical first protrusion 111. The end of the first protrusion 111 facing the damper 2 is provided with an opening. The inner periphery of the first protrusion 111 forms a mounting hole 1111 for screwing and assembling with the mounting hole 3151. The outer periphery of the first protrusion 111 is connected with a plurality of reinforcing protrusions 1121 distributed along the outer periphery of the first protrusion 111. The side wall of the upper protrusion 315 located on the left side of the snap-fit ​​groove 311 abuts against the opening end of the first protrusion 111. The outer side wall of the cavity 312 located at the top of the snap-fit ​​groove 311 abuts against the outer periphery of the first protrusion 111.

[0055] There are two mounting holes 3151, which are distributed in the front and rear directions of the snap-fit ​​groove to improve the connection strength between the positioning body 31 and the mounting groove 11.

[0056] To facilitate the fixing of the positioning body 31 onto the mounting groove 11 and thus onto the washing machine cover 1, the mounting hole 3151 is configured as a threaded hole; the threaded hole and the assembly hole 1111 are fixedly connected by screws or other connecting parts.

[0057] Furthermore, due to the aforementioned structure, the stress required to fix the damper 2 is concentrated at the mounting hole 3151. Therefore, this part bears the main force required for opening and closing the washing machine lid 1, and its structural strength determines the effective number of times the washing machine lid can be flipped. To further improve the service life of this part, reinforcing ribs extending vertically from the snap-fit ​​groove 311 are provided on the upper rib 315 to enhance the structural strength at the mounting hole.

[0058] In an embodiment of the present invention, a lower protruding rib 316 is provided on the outer wall of the cavity 312 at the bottom of the snap-fit ​​groove 311. The lower protruding rib 316 extends in the front-back direction of the snap-fit ​​groove 311. The side wall of the mounting groove 11 is provided with an insertion groove 1121. The lower protruding rib 316 is inserted into the insertion groove 1121 in the up-down direction of the snap-fit ​​groove 311.

[0059] In an embodiment of the present invention, the lower rib 316 is inserted into the insertion groove 1121, which further increases the assembly strength between the positioning body and the mounting groove, thereby further stabilizing the housing of the damper 2.

[0060] Specifically, the side wall of the mounting groove 11 is provided with a second protruding rib 112, and the second protruding rib 112 is recessed to form a insertion groove 1121 with the groove opening facing the lower protruding rib 316; the insertion groove 1121 is open in the front and rear directions of the snap-fit ​​groove, which facilitates the insertion of the lower protruding rib 316 into the insertion groove 1121.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced.
