Specifically, an outer shell 10 fixedly connected with the outer barrel is arranged in the box body; and a mounting seat 6 is fixed at one end of the outer shell 10 close to the power unit 1.

Wherein, the clutch sleeve 4 is connected with the washing input shaft 11 in a spline fit way.

The first planetary gear train 2 is arranged between the mounting seat 6 and the clutch sleeve 4 and can move along the washing input shaft 11 under the action of the power conversion unit so as to be fixedly connected with one of the clutch sleeve 4 or the mounting seat 6. The first planetary gear train 2 includes a first carrier 24, a first sun gear 21, a first planetary gear 22, and a first ring gear 23. The first carrier 24 is provided with a first planet post for fastening the first planet wheel 22, and the first planet wheel 22 can freely rotate around the first planet post. And the first planetary gears 22 simultaneously mesh with the external teeth of the first sun gear 21 and the internal teeth of the first ring gear 23. In addition, a connecting convex ring 25 is formed by extending the first inner gear ring 23 to one side close to the mounting seat 6, and the connecting convex ring 25 is connected with the dehydration input shaft 13 in a key mode. One end of the dehydration input shaft 13 far away from the connecting convex ring 25 is fixedly connected with the dehydration output shaft 14 through the second shell 7. That is, the dehydration input shaft 13, the second housing 7 and the dehydration output shaft 14 are fixed to be one body and rotated at the same time. In addition, the mounting seat 6 is of a hollow structure and is sleeved outside the connecting convex ring 25, and a spring 9 sleeved outside the dehydration input shaft 43 is arranged between the connecting convex ring and the outer shell 10.

In the above, the first sun gear 21 is fixedly connected to the washing input shaft 11, and the washing input shaft 11 drives the first sun gear 21 to rotate. One end of the first carrier 24 close to the mounting seat 6 is formed with circumferentially arranged first coupling teeth 28, and one end of the first carrier 24 close to the power unit 1 is formed with circumferentially arranged second coupling teeth 27. Wherein the first coupling teeth 28 are intended to engage with the second mating teeth 60 on the mounting seat 6 and the second coupling teeth 27 are intended to engage with the first mating teeth 40 on the clutch sleeve 4. In addition, the first carrier 24 includes a first casing 20 accommodating the first sun gear 21, the first planet gear 22, and the first ring gear 23, and the first casing 20 is provided with a boss 26 disposed along a circumferential direction thereof. The dewatering input shaft 13 is sleeved outside the washing input shaft 11.

In this embodiment, the connection convex ring 25 is connected with the dehydration input shaft 13 by spline fitting. The first sun gear 21 is connected with the washing input shaft 11 by spline fitting.

The dehydration output shaft 14 is sleeved outside the washing output shaft 12, and the washing output shaft 12 and the dehydration output shaft 14 are connected through a bearing so as to ensure that the two can rotate circumferentially mutually. Similarly, the dewatering input shaft 13 is sleeved outside the washing output shaft 12, and the washing input shaft 11 and the dewatering input shaft 13 are connected through a bearing so as to ensure that the two can rotate circumferentially relative to each other.

The power conversion unit includes a retractor and a shift lever 50 fixed to the mount 6. The retractor controls the shift lever 50 to move so as to control the position of the first planetary gear train 2 on the washing input shaft 11 through the shift lever 50, so that the first planetary gear train 2 is fixed with one of the mounting seat 6 or the clutch sleeve 4, thereby realizing power conversion. In this example, a cam-type retractor is adopted, the shift lever 50 is connected with the traction cam through a tension spring, the tension spring is connected with the shift lever 50 through a tension spring shaft, and the shift lever 50 is connected with the mounting seat 6 through a pin shaft. As another practical way, the output end of the retractor is set as a traction rope, and a motor inside the retractor drives the traction rope to extend and contract after being decelerated, so as to control the shift lever 50. As another practical way, the output end of the retractor is a rotating shaft type, one end of the tension spring is directly fixed on the rotating shaft, the other end of the tension spring is fixed on the shift lever 50, and the shift lever 50 is controlled to stop at different positions through the rotating angle of the rotating shaft. When the pulsator washing machine system is in an initial state, the control retractor is in an initial position, the deflector rod 50 is in an open state, the deflector rod 50 does not interact with the boss 26 on the outer side of the first planet carrier 24, at the moment, the first planet carrier 24 is separated from the mounting seat 6 under the action of the spring 9, and the second connecting teeth 27 on the first planet carrier 24 are meshed with the first matching teeth 40 on the clutch sleeve 4.

In a washing mode, as shown in fig. 1-3, the shift lever 50 rotates a certain angle, and after the shift lever 50 contacts with the boss 26 on the first planet carrier 24, the shift lever 50 continues to rotate, so that the shift lever 50 drives the first planet carrier 24 to move towards the mounting seat 6 against the elastic force of the spring 9, the second coupling teeth 27 on the first planet carrier 24 are separated from the second mating teeth 60 on the clutch sleeve 4, and the first coupling teeth 28 on the first planet carrier 24 are engaged with the second mating teeth 60 on the mounting seat 6. With the mounting block 6 fixed to the outer housing 10, the first carrier 24 is locked after the first coupling teeth 28 on the first carrier 24 engage with the second mating teeth 60 on the mounting block 6.

The power unit 1 is operated, and the washing input shaft 11 is rotated and rotates the first sun gear 21 and the second sun gear 31. The first sun gear 21 drives the first planet gear 22 to rotate, and the first planet gear 22 only rotates because the first planet carrier 24 and the mounting base 6 are fixed and immovable; according to the planetary gear train transmission principle, the first sun gear 21 transmits power to the first ring gear 23 through the first planet gears 22, and the first sun gear 21 is rotated in the opposite direction to the first ring gear 23. Meanwhile, the first inner gear ring 23 synchronously transmits the rotation thereof to the dehydration input shaft 13, the second shell 7 and the dehydration output shaft 14, and finally the dehydration output shaft 14 drives the inner barrel to rotate in the same direction. In addition, the first sun gear 21 and the second sun gear 31 rotate in the same direction, and drive the second planet carrier 34 to rotate in the same direction, and the second planet carrier 34 drives the washing output shaft 12 to rotate in the same direction. In this way, the dehydration output shaft 14 and the first ring gear 23 rotate in the same direction, and the washing output shaft 12 and the first sun gear 21 rotate in the same direction. Namely, when the first planet carrier 24 is matched and connected with the mounting seat 6, the dehydration output shaft 14 and the washing output shaft 12 rotate reversely. The inner tub and the pulsator rotate in opposite directions to enhance washing power, thereby reducing twisting.

Dehydration mode, as shown in fig. 4-8, release lever 50, retractor in initial position; the shift lever 50 is separated from the boss 26 on the first carrier 24 and has no interaction force. Under the action of gravity and the restoring force of the spring 9, the first planet carrier 24 moves towards the direction close to the clutch sleeve 4, the first connecting teeth 28 on the first planet carrier 24 are separated from the second matching teeth 60 on the mounting seat 6, the second connecting teeth 27 on the first planet carrier 24 are meshed with the second matching teeth 60 on the clutch sleeve 4, and the first planet carrier 24 is fixedly connected with the clutch sleeve 4.

The power unit 1 works, the washing input shaft 11 rotates, and the clutch sleeve 4, the first sun gear 21 and the second sun gear 31 are driven to rotate in the same direction. At this time, the first carrier 24 and the washing input shaft 11 are fixed by the clutch sleeve 4, the first carrier 24 and the washing input shaft 11 rotate in the same direction, the first planetary gear 22 revolves around the washing input shaft 11 on one hand and rotates in the other direction, and the first ring gear 23 is driven to rotate. According to the transmission principle of a planetary gear train, the first inner gear ring 23, the first planet carrier 24 and the first sun gear 21 keep rotating in the same direction and at the same speed; therefore, the dehydration input shaft 13 and the washing input shaft 11 keep rotating in the same direction. The first inner gear ring 23 synchronously transmits the rotation to the dehydration input shaft 13, the second shell 7 and the dehydration output shaft 14, and finally the dehydration output shaft 14 drives the inner barrel to rotate in the same direction. The first sun gear 21 and the second sun gear 31 rotate in the same direction and drive the second planet carrier 34 to rotate in the same direction, and the second planet carrier 34 drives the washing output shaft 12 to rotate in the same direction. In the above, the dehydration output shaft 14 and the first ring gear 23 rotate at the same speed and in the same direction, and the washing output shaft 12 and the first sun gear 21 rotate in the same direction. Namely, when the first planetary gear train 2 is fixedly connected with the clutch sleeve 4, the dehydration output shaft 14 and the washing output shaft 12 rotate in the same direction, and the inner barrel and the wave wheel rotate in the same direction. At the moment, the power unit 1 rotates unidirectionally at a high speed to drive the inner barrel and the impeller to rotate at a high speed so as to realize the dewatering and spin-drying effects.
