[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0029] First embodiment

[0030] See also Figure 1-Figure 6 The washing and drying transmission mechanism of the pulsator washing machine includes a motor 1, a driving spindle 2, and a pulsator 3. The driving spindle 2 is directly driven and connected to the pulsator 3, and a spindle outer sleeve 4 is sleeved on the outer side thereof. The spindle outer sleeve 4 is driven and connected to an inner barrel 5.

[0031] The motor 1 is directly connected to the driving spindle 2. In this embodiment, the power output end of the motor 1 is connected to the driving connection recess at the lower end of the driving spindle 2, so that the power output by the motor 1 can be directly transmitted to the driving spindle 2. The motor 1 and the driving spindle 2 are nested to achieve drive matching.

[0032] An active friction disc 7 is arranged on the driving spindle 2, a passive friction disc 8 is arranged on the spindle outer sleeve 4, and a damping material layer for damping is arranged between the active friction disc 7 and the passive friction disc 8.

[0033] In this embodiment, when the pulsator washing machine is not equipped with a clutch, the working characteristics of the motor 1 rotating in different directions and outputting different speeds during washing and dehydration are utilized, and the damping effect of the damping material layer between the active friction disk 7 and the passive friction disk 8 is combined, so that a damping transmission connection can be achieved between the driving spindle 2 and the spindle jacket 4, so that the two can produce different rotational resistance torque changes during operation, and finally the pulsator 3 and the inner drum 5 can frequently perform mutually delayed rotations in opposite directions to complete washing, and perform synchronous rapid rotation to complete dehydration. This not only effectively simplifies the overall structure of the pulsator washing machine and reduces production costs, but also, under the same external dimensions, the pulsator washing machine has a larger washing and dehydration space. In addition, the damping material layer also has a lubricating effect, which can reduce the friction and abnormal noise generated between the driving spindle 2 and the spindle jacket 4 during transmission, so that the operation of the pulsator washing machine is more stable and quiet, and the service life is longer.

[0034] As a preferred solution of this embodiment, it may also have the following additional technical features:

[0035] The active friction disc 7 is fixedly arranged at the lower part of the driving main shaft 2, and the passive friction disc 8 is fixedly arranged at the lower part of the main shaft outer sleeve 4; the active friction disc 7 and the passive friction disc 8 are in contact with each other.

[0037] A recess 9 is provided on the active friction disc 7 and / or the passive friction disc 8 , and the damping grease is stored in the recess 9 .

[0038] In this embodiment, recesses 9 are provided on both the active friction disc 7 and the passive friction disc 8 .

[0039] The provision of the recess 9 can facilitate the storage of the damping grease and reduce the number of times the damping grease is applied.

[0040] The concave portion 9 is in a dot shape, a straight line shape, a spiral shape, a wave shape or a combination thereof. That is, the concave portion 9 can be formed in a variety of different shapes.

[0041] Meanwhile, one or more recesses 9 are provided.

[0042] like Figure 3 As shown, the recess 9 is an S-shaped groove, and there are a plurality of recesses 9 , which are arranged in a circular array on the active friction disk 7 with the driving spindle 2 as the center.

[0043] like Figure 4 As shown, the recess 9 is a linear groove, and a plurality of recesses 9 are provided. The plurality of recesses 9 are arranged on the active friction disc 7 and extend divergently along the periphery with the driving spindle 2 as the center.

[0044] like Figure 5 As shown, the recessed portion 9 is a linear groove, and a plurality of recessed portions 9 are provided. The plurality of recessed portions 9 are provided to extend divergently along the periphery with the passive friction disc 8 as the center.

[0045] like Figure 6 As shown, the recessed portion 9 is point-shaped and is provided in a plurality of them. The plurality of recessed portions 9 are arranged divergently and at intervals along the periphery with the passive friction disc 8 as the center.

[0046] In this embodiment, the active friction disc 7 and the passive friction disc 8 are both made of wear-resistant materials. The active friction disc 7 and the passive friction disc 8 can be provided with a recess 9 for storing damping grease according to actual use requirements. The recess 9 can be in the shape of a groove or a hole, and the shape, size and number of the groove or hole are various.

[0047] In addition, the damping material layer can also be a damping plate arranged between the active friction disc 7 and the passive friction disc 8, and the active friction disc 7 and the passive friction disc 8 are matched with each other through a damping transmission of the damping plate.

[0048] By utilizing the damping effect of the damping plate, a damping transmission fit can be achieved between the active friction disc 7 and the passive friction disc 8 .

[0049] The driving spindle 2 is directly sleeved in the spindle housing 4 , that is, the driving spindle 2 directly rotates in the spindle housing 4 .

[0050] A convex edge 11 is further provided on the periphery of the active friction disc 7 , the passive friction disc 8 is supported on the active friction disc 7 , and the convex edge 11 surrounds the passive friction disc 8 .

[0051] An outer barrel 12 is arranged outside the inner barrel 5, and an inner barrel fixing plate 13 is fixedly arranged at the bottom; the motor 1 is fixedly arranged on the outer barrel 12; the upper end of the driving main shaft 2 extends into the outer barrel 12 and is directly connected to the driving of the impeller 3; the main shaft outer sleeve 4 is fixedly matched with the inner barrel fixing plate 13.

[0052] Here’s how it works:

[0053] When the pulsator washing machine is in washing operation: water enters the inner barrel 5 of the pulsator washing machine, and the motor 1 drives the pulsator 3 to rotate forward and reversely by transmitting torque through the driving spindle 2 to achieve clothing washing. Because the inner barrel 5 is mounted on the driving spindle 2 through the inner barrel fixing plate 13 and the spindle outer sleeve 4, and the driving spindle 2 is connected to the spindle outer sleeve 4 through the cooperation between the active friction disc 7 and the passive friction disc 8, the inner barrel 5 is in a freely rotatable state, and it will not immediately follow the pulsator 3 to rotate in the same direction. In this process, the damping force of the damping material layer between the active friction disc 7 and the passive friction disc 8 is less than or equal to the rotational resistance torque suffered by the spindle outer sleeve 4 and the inner barrel 5. Therefore, the inner barrel 5 is delayed to follow the rotation due to the damping material layer and friction between the active friction disc 7 and the passive friction disc 8, and the water flow stirred by the pulsator 3 will also drive the inner barrel 5 to delay the rotation. Because the pulsator 3 rotates continuously in the forward and reverse directions, and the inner tub 5 rotates continuously with a delay, the pulsator 3 and the inner tub 5 frequently rotate in the opposite directions during rotation, thereby achieving the washing of the pulsator washing machine and making the effects of turning over and scrubbing the clothes better.

[0054] When the pulsator washing machine is in dehydration operation: the motor 1 drives the driving spindle 2 to rotate in a single direction. Since the spindle outer sleeve 4 is connected to the inner barrel fixing plate 13 and the inner barrel 5 as a whole, the inner barrel 5 also starts to rotate under the action of the damping material layer and friction between the driving spindle 2, the active friction disc 7, and the passive friction disc 8. As the rotation speed of the driving spindle 2 gradually increases, the damping material layer between the active friction disc 7 and the passive friction disc 8 gradually increases the rotational driving torque of the spindle outer sleeve 4 and the inner barrel 5, and is greater than or equal to the rotational resistance torque of the spindle outer sleeve 4 and the inner barrel 5. In this way, the spindle outer sleeve 4 and the inner barrel 5 can achieve synchronous and rapid rotation with the pulsator 3, achieving the purpose of high-speed dehydration.

The coupling 6 is drivingly connected to the drive connection protrusion at the lower end of the drive spindle 2 through the drive assembly hole at the upper end, and the coupling 6 is drivingly connected to the power output end of the motor 1 through the drive assembly hole at the lower end, so that the power output by the motor 1 is transmitted to the drive spindle 2 through the coupling 6.
