As shown in FIG. 1 , the pulsator washing machine 100 further includes an outer tub 2 , an inner tub 3 and a pulsator 4 disposed in the box body 1 . The outer tub 2 has a small predetermined rotation angle relative to the box body 1. If the central axis of the outer tub 2 is the rotation center of the outer tub 2, the predetermined rotation angle is about 5°, for example. The inner tub 3 is arranged inside the outer tub 2 and can be rotated relative to the outer tub 2 . The inner tub 3 has a storage space for placing laundry. The pulsator 4 is disposed inside the inner tub 3 and at the bottom of the inner tub 3 , and can rotate relative to the inner tub 3 . The rotation center axis of the pulsator 4 is collinear with the rotation center axis of the inner tub 3 . The upper surface of the pulsator 4 is provided with a stirring rib, and the stirring rib is used to agitate the water flow, thereby realizing the washing of the clothes. In order to facilitate the observation of the external structure of the outer tub 2 , FIGS. 2 and 3 are illustrated in an inverted manner in which the bottom of the outer tub 2 is placed on top and the top is placed on the bottom.

In some embodiments, the outer tub 2 may be used to store wash water. In other embodiments, the outer tub 2 is not used for storing wash water, but only serves as a carrier for support.

As shown in FIG. 1 , the pulsator washing machine 100 further includes a power system 5 and a casing 6 disposed in the box body 1 . The casing 6 is sleeved on the outer side of part of the power system 5 . As shown in FIG. 1 , the casing 6 is sleeved on the outer side of the deceleration mechanism 54 . As shown in FIG. 4A and FIG. 4B , the casing 6 includes a lower casing 61 and an upper casing 62 , and the lower casing 61 and the upper casing 62 may be fixedly connected by bolts, for example. The upper casing 62 is fixedly connected to the outer tub 2 , so the casing 6 is fixed relative to the outer tub 2 . For the convenience of observation, in FIG. 4B , an inverted manner in which the lower casing 61 is placed on the upper side and the upper casing 62 is placed on the bottom is illustrated.

The power system 5 can generate a driving force that drives the inner tub 3 and the pulsator 4 to rotate. Under the driving of this driving force, the pulsator washing machine 100 can have three washing modes: a rotating tub washing mode in which the inner tub 3 and the pulsator 4 rotate in the same direction ; The hand rubbing washing mode in which the inner barrel 3 and the pulsator 4 rotate in opposite directions; the pulsator washing mode in which only the pulsator 4 rotates and the inner barrel 3 stops rotating.

As shown in FIG. 4A , the power system 5 includes a motor 51 , a gear switching mechanism 52 , an input shaft mechanism 53 connected to the gear switching mechanism 52 , a reduction mechanism 54 connected to the input shaft mechanism 53 , and an output connected to the reduction mechanism 54 . Shaft mechanism 55 . The following is an example to illustrate the composition of each institution and the connection relationship between each institution.

As shown in FIGS. 1 and 2 , the motor 51 is provided on the tub 2 (the motor 51 is omitted in FIG. 3 ). The axis of the power output shaft of the motor 51 is collinear with the rotation center axis of the inner tub 3 and the pulsator 4 , and the driving force generated by the motor 51 can drive the inner tub 3 and the pulsator 4 to rotate.

As shown in FIG. 4A , the input shaft mechanism 53 includes a washing input shaft 531 and a dehydration input shaft 532 . The dehydration input shaft 532 is a hollow shaft, the washing input shaft 531 is arranged in the inner hollow of the dehydration input shaft 532, and the washing input shaft 531 and the dehydration input shaft 532 can rotate independently of each other. For example, a bearing may be provided between the washing input shaft 531 and the dehydration input shaft 532 to allow one of the washing input shaft 531 and the dehydration input shaft 532 to rotate relative to the other. The power output shaft of the motor 51 can be directly connected to the washing input shaft 531 , so that the rotation speed of the washing input shaft 531 is the rotation speed of the power output shaft of the motor 51 . Alternatively, the power output shaft of the motor 51 can be connected to the washing input shaft 531 through a belt transmission mechanism, and the transmission ratio of the belt transmission mechanism can be set so that the rotation speed of the washing input shaft 531 and the rotation speed of the power output shaft of the motor 51 different. Since the rotation speed of the motor 51 is usually fast, in general, the belt transmission mechanism is usually a deceleration mechanism, which can make the rotation speed of the washing input shaft 531 smaller than the rotation speed of the power output shaft of the motor 51 .

As shown in FIG. 4A , the gear switching mechanism 52 includes an upper gear sleeve 521 , a connecting member 522 , a lower gear holder 523 and a compression spring 524 . The connecting piece 522 is sleeved on the outer side of the dehydration input shaft 532, and the connecting piece 522 includes a spline groove arranged on the inner side wall thereof. The connector 522 is connected with the dehydration input shaft 532 by spline connection, so that the connector 522 can not only slide up and down along the dehydration input shaft 532 , but also rotate in the same direction with the dehydration input shaft 532 .

As shown in FIG. 4C , the connector 522 further includes a first tooth slot structure 5221, and the first tooth slot structure 5221 can be used to make the connector 522 cooperate with the lower tooth base 523; the upper tooth sleeve 521 includes a second tooth slot structure 5211, The connecting member 522 can be matched with the upper tooth sleeve 521 by using the second tooth slot structure 5211 . The connecting piece 522 may also not cooperate with the upper tooth sleeve 521 and the lower tooth base 523 . In this case, the connecting piece 522 is located between the upper tooth sleeve 521 and the lower tooth base 523 . The different connection relationship between the input shaft mechanism 53 and the deceleration mechanism 54 is realized by the connecting piece 522 being matched with the upper gear sleeve 521, or with the lower gear holder 523, or not matched with the upper gear sleeve 521 and the lower gear holder 523. Then, the selection of the washing mode of the pulsator washing machine 100 is controlled, and the detailed process will be introduced later.

The upper gear sleeve 521 is fixedly connected with the washing input shaft 531 , and can also be integrally designed with the washing input shaft 531 . The upper gear sleeve 521 rotates in the same direction with the washing input shaft 531 . The connecting piece 522 also includes teeth and slots that are matched with the second tooth groove structure 5211 of the upper toothed sleeve 521, so that the upper toothed sleeve 521 can be closely matched with the connecting piece 522 to prevent the teeth from being dislodged.

As shown in FIGS. 4A to 4C , the lower tooth holder 523 is fixedly connected to the lower casing 61 , because the lower casing 61 is fixedly connected to the upper casing 62 , and the upper casing 62 is fixedly connected to the outer tub 2 . The tooth base 523 is fixedly connected to the lower casing 61 , which ensures that the lower tooth base 523 is fixed relative to the outer tub 2 and does not rotate. The lower tooth holder 523 includes teeth and slots which are matched with the first tooth slot structure 5221 of the connecting piece 522 , so that the lower tooth holder 523 can be closely matched with the connecting piece 522 to prevent the teeth from being dislodged.

As shown in FIG. 4A , a compression spring 524 is disposed between the lower tooth holder 523 and the connecting piece 522 for applying an elastic force to the connecting piece 522 to move the connecting piece 522 toward the upper tooth sleeve 521 . Due to the existence of the compression spring 524, the connecting piece 522 will remain in cooperation with the upper tooth sleeve 521 under the condition of not being acted by other external forces.

As shown in FIG. 4A , the speed reduction mechanism 54 includes a brake housing 540 and a planetary gear train located in the brake housing 540 ; the output shaft mechanism 55 includes a washing output shaft 551 and a dehydration output shaft 552 .

The dehydration output shaft 552 is a hollow shaft, the washing output shaft 551 is arranged in the inner hollow of the dehydration output shaft 552, and the washing output shaft 551 and the dehydration output shaft 552 can rotate independently of each other. For example, a bearing may be provided between the washing output shaft 551 and the dehydration output shaft 552 to allow one of the washing output shaft 551 and the dehydration output shaft 552 to rotate relative to the other.

As shown in FIG. 4D , the planetary gear train includes a ring gear 541 , at least one planetary gear 542 , a planetary carrier 543 and a sun gear 544 .

The sun gear 544 is located at the end of the washing input shaft 531 , and the driving force generated by the motor 51 is transmitted to the sun gear 544 through the washing input shaft 531 . One end of the planet carrier 543 is connected to the rotating shaft 5421 of each planetary gear 542 (the planetary gear 542 revolves around the sun gear 544 and rotates around the respective rotating shaft 5421 ), and the other end is fixedly connected to the washing output shaft 551 . The washing output shaft 551 is fixedly connected with the pulsator 4 , so the sun gear 544 can drive the planet carrier 543 to rotate, and then drive the washing output shaft 551 to rotate, thereby driving the pulsator 4 to rotate.

The ring gear 541 is fixed on the inner wall of the brake housing 540 , or the ring gear 541 is integrally formed with the brake housing 540 . Each planetary gear 542 meshes with the ring gear 541 to form an internal meshing structure, and meshes with the sun gear 544 to form an external meshing structure. In this case, when the rotation of the brake housing 540 is not restricted, the sun gear 544 can drive the planetary gears 542 to rotate through external meshing, and the planetary gears 542 further drive the ring gear 541 to rotate through internal meshing. However, when the rotation of the brake housing 540 is restricted, each planetary gear 542 will not drive the ring gear 541 to rotate. One end of the dehydration output shaft 552 is fixedly connected to the brake housing 540, and the other end is fixedly connected to the inner tub 3. Therefore, when the sun gear 544 drives each planetary gear 542 to rotate, and then drives the ring gear 541 to rotate, the ring gear 541 and the brake The housing 540 is fixed, so the dehydration output shaft 552 can also be driven to rotate by the braking housing 540 , thereby realizing the rotation of the inner tub 3 . However, when the rotation of the brake housing 540 is restricted, neither the dehydration output shaft 552 nor the inner tub 3 rotates.

When the connecting member 522 is tightly fitted with the upper gear sleeve 521, since the upper gear sleeve 521 and the washing input shaft 531 are engaged by spline connection and rotate in the same direction, the connecting member 522 and the washing input shaft 531 rotate in the same direction. In addition, since the connecting member 522 and the dehydration input shaft 532 are engaged with each other through spline connection and rotate in the same direction, the dehydration input shaft 532 and the washing input shaft 531 rotate in the same direction. It can be seen from the above that the dehydration input shaft 532 is fixedly connected to the brake housing 540, the brake housing 540 is fixedly connected to the dehydration output shaft 552, and the dehydration output shaft 552 is fixedly connected to the inner tub 3; the washing input shaft 531 is connected to the planet carrier 543, The planet carrier 543 is connected with the washing output shaft 551, and the washing output shaft 551 is fixedly connected with the pulsator 4. Therefore, when the dehydration input shaft 532 and the washing input shaft 531 rotate in the same direction, the inner tub 3 and the pulsator 4 rotate in the same direction. In this case Next, the pulsator washing machine 100 is in the drum washing mode.

When the connecting piece 522 is tightly fitted with the lower tooth holder 523, since the lower tooth holder 523 is fixedly connected with the lower casing 61, the lower casing 61 is fixedly connected with the upper casing 62, and the upper casing 62 is fixedly connected with the outer tub 2, Therefore, the connection member 522 is fixed relative to the outer tub 2 . And because the dehydration input shaft 532 is engaged with the connecting member 522 through spline connection, when the connecting member 522 is fixed relative to the outer tub 2 , the dehydrating input shaft 532 is also fixed relative to the outer tub 2 . And because the dehydration input shaft 532 is fixedly connected to the brake housing 540, the brake housing 540 is fixedly connected to the dehydration output shaft 552, and the dehydration output shaft 552 is fixedly connected to the inner tub 3, so when the dehydration input shaft 532 is fixed relative to the outer tub 2 When not moving, the inner tub 3 is also fixed. The washing input shaft 531 only drives the planetary carrier 543 to move, and the planetary carrier 543 drives the washing output shaft 551 to rotate, thereby driving the pulsator 4 to rotate. When the inner tub 3 is fixed and only the pulsator 4 rotates, the pulsator washing machine 100 is in the pulsator washing mode.

When the connecting piece 522 is not matched with the upper gear sleeve 521 and the lower gear holder 523, the driving force generated by the motor 51 drives the washing input shaft 531 to rotate, and then drives the sun gear 544 to rotate, and the washing input shaft 531 and the sun gear 544 rotate in the same direction . The rotation of the sun gear 544 drives each planetary gear 542 to rotate. The rotation of each planetary gear 542 drives the planet carrier 543 to rotate, which in turn drives the pulsator 4 to rotate, and drives the ring gear 541 to rotate, which in turn drives the inner tub 3 to rotate. Since each planetary gear 542 forms an external meshing structure with the sun gear 544 and each planetary gear 542 forms an internal meshing structure with the ring gear 541, and since the steering of the two gears is the same during internal meshing, and the steering of the two gears is opposite during external meshing, therefore The rotation directions of the planetary gears 542 and the ring gear 541 are the same, and the rotation direction of the sun gear 544 is opposite. That is, the rotation directions of the sun gear 544 and the ring gear 541 are opposite. When the rotation directions of the sun gear 544 and the ring gear 541 are opposite, the rotation directions of the washing output shaft 551 and the dehydration output shaft 552 are opposite, and the rotation of the pulsator 4 and the inner tub 3 are also opposite. Therefore, when the connecting member 522 is not matched with the upper tooth sleeve 521 and the lower tooth holder 523, the pulsator 4 and the inner tub 3 rotate in the opposite direction, and the pulsator washing machine 100 is in the hand washing mode.

From the above, it can be seen that when the connecting member 522 is closely matched with the upper tooth sleeve 521, the pulsator washing machine 100 is in the drum washing mode in which the inner tub 3 and the pulsator 4 rotate in the same direction; The pulsator washing machine 100 is in the pulsator washing mode in which the inner tub 3 does not move and the pulsator 4 rotates; when the connecting member 522 is not matched with the upper tooth sleeve 521 and the lower tooth seat 523, the pulsator washing machine 100 is in the inner tub 3 and the pulsator 4 reverse. Scrub wash mode towards rotating hand.

As shown in FIGS. 5A to 5C, 6A to 6B, and 7A to 7B, in order to make the connecting piece 522 cooperate with the upper tooth sleeve 521 or the lower tooth seat 523, or not cooperate with both the upper tooth sleeve 521 and the lower tooth seat 523, The pulsator washing machine 100 also includes a lever 7 and a first torsion spring rotating shaft 16 arranged in the middle part of the lever 7 and connected with the middle part of the lever 7, and a swing lever 8 and a swing lever 8 arranged in the middle part of the swing lever 8. 8. The second torsion spring shaft 18 connected in the middle part.

As shown in FIGS. 5A-5B , the lever 7 includes a first lever arm 701 and a second lever arm 702 , and the first lever arm 701 and the second lever arm 702 are connected to each other to form a substantially L-shaped structure. In some embodiments, the included angle between the first lever arm 701 and the second lever arm 702 is an obtuse angle. The first torsion spring shaft 16 is disposed at the connection between the first lever arm 701 and the second lever arm 702 . The distal end of the first lever arm 701 can abut against the housing 6 . The end of the second lever arm 702 is bifurcated and can abut against the connecting member 522 . The connecting piece 522 includes a main body 5222 and a flange 5223 connected with the main body 5222. The end of the second lever arm 702 can be located outside the main body 5222 but not in contact with the main body 5222, so as to avoid contact with the second lever arm when the connecting piece 522 is rotated. 702 creates friction. Since the included angle between the first lever arm 701 and the second lever arm 702 is an obtuse angle, when the end of the first lever arm 701 abuts against the housing 6, the end of the second lever arm 702 and the convex The flange 5223 is separated, and when the end of the second lever arm 702 abuts against the flange 5223, the end of the first lever arm 701 is separated from the housing 6 .

The first torsion spring shaft 16 is used to apply an elastic force to the lever 7 to drive the lever 7 to rotate in the first direction, and the first direction is the direction of rotation that makes the end of the first lever arm 701 of the lever 7 close to the housing 6 . The first torsion spring rotating shaft 16 includes a first rotating shaft and a first torsion spring sleeved on the first rotating shaft. After the lever 7 is installed on the housing 6 through the first rotation shaft torsion spring 16 , the first torsion spring is elastically deformed, thereby forcing the end of the first lever arm 701 of the lever 7 to abut against the housing 6 .

As shown in FIG. 5C , the rocker 8 includes a first rocker arm 801 and a second rocker arm 802 , and the first rocker arm 801 and the second rocker arm 802 are connected to each other to form a substantially L-shaped structure. In some embodiments, the included angle between the first swing lever arm 801 and the second swing lever arm 802 is an obtuse angle. The second torsion spring shaft 18 is disposed at the connection between the first swing lever arm 801 and the second swing lever arm 802 . The end of the first rocker arm 801 can abut against the housing 6 , and the end of the second rocker arm 802 can approach the housing 6 . In addition, the end of the second rocker arm 802 can also abut against the lever 7 . For example, the end of the second swing lever arm 802 can abut against the side limiting rib 71 of the lever 7 (see FIG. 5B for the structure of the side limiting rib 71 ). Since the included angle between the first rocker arm 801 and the second rocker arm 802 is an obtuse angle, when the end of the first rocker arm 801 abuts against the housing 6, the end of the second rocker arm 802 and the housing The body 6 moves away, and when the end of the second rocker arm 802 approaches the housing 6 , the end of the first rocker arm 801 is separated from the housing 6 .

The second torsion spring rotating shaft 18 is used to apply an elastic force to the swing rod 8 to drive the swing rod 8 to rotate counterclockwise (counterclockwise when viewed in the state shown in FIG. 5C ). The second torsion spring rotating shaft 18 includes a second rotating shaft and a second torsion spring sleeved on the second rotating shaft. After the swing rod 8 is installed on the housing 6 through the second torsion spring shaft 18, the second torsion spring is elastically deformed, thereby forcing the end of the first swing rod arm 801 to abut against the housing 6 and forcing the first The ends of the two swing lever arms 802 are away from the housing 6 .

The swing rod 8 can rotate about the second torsion spring shaft 18 and stay in two positions.

When the swing lever 8 is in the first swing position, under the action of the second torsion spring shaft 18 , the end of the first swing lever arm 801 abuts against the casing 6 , and the end of the second swing lever arm 802 is away from the casing 6 , and abut against the side limiting rib 71 of the lever 7 . The end of the first lever arm 701 of the lever 7 rotates in a direction away from the housing 6 under the action of the second swing lever arm 802 .

When the swing lever 8 is in the second swing position, the end of the first swing lever arm 801 is separated from the housing 6 , and the end of the second swing lever arm 802 is at the position closest to the housing 6 and is close to the side of the lever 7 . The limiting ribs 71 are separated. The end of the first lever arm 701 of the lever 7 rotates in the direction of approaching the housing 6 under the action of the first torsion spring rotating shaft 16 .

Under the cooperation of the swing rod 8 , the lever 7 can rotate around the first torsion spring shaft 16 and stay at three positions. Moreover, with the rotation of the lever 7, the connecting piece 522 can slide up and down along the dehydration input shaft 532, so as to cooperate with the upper tooth sleeve 521 or the lower tooth holder 523, or not cooperate with the upper tooth sleeve 521 and the lower tooth holder 523. .

As shown in FIG. 5A , when the lever 7 is in the first position, the end of the first lever arm 701 abuts against the housing 6 , and the end of the second lever arm 702 is separated from the flange 5223 to the greatest extent. As shown in FIG. 5B , the lever 7 further includes an inner limiting rib 72 , and the inner limiting rib 72 abuts against the housing 6 . But the inner limit rib 72 is not necessary.

As shown in FIG. 5C , the swing lever 8 is at the second swing position under the action of external force, that is, the end of the first swing lever arm 801 is separated from the housing 6 , and the end of the second swing lever arm 802 is in contact with the case 6 . The closest position is separated from the side limiting rib 71 of the lever 7 . Under the action of the compression spring 524 , the connecting piece 522 slides in a direction close to the upper gear sleeve 521 until it cooperates with the upper gear sleeve 521 . In this case, the pulsator washing machine 100 is in the drum washing mode in which the inner tub 3 and the pulsator 4 rotate in the same direction.

As shown in FIG. 6A, when the lever 7 is in the second position, the end of the first lever arm 701 is separated from the housing 6, but not to the greatest extent; the end of the second lever arm 702 is separated from the flange 5223 Abut and press the connecting piece 522 to slide toward the lower tooth holder 523 under the action of the first external force, so that the connecting piece 522 is disengaged from the upper tooth sleeve 521 and has not yet been matched with the lower tooth holder 523 .

As shown in FIG. 6B , at this time, the external force acting on the swing rod 8 disappears, and the swing rod 8 is at the first swing position under the action of the second torsion spring rotating shaft 18 , that is, the end of the first swing rod arm 801 and the housing 6 abuts, and the end of the second swing lever arm 802 is far away from the housing 6 and abuts against the side limiting rib 71 of the lever 7 . It is clear that the aforementioned first external force is the elastic force applied by the second torsion spring rotating shaft 18 to the lever 7 through the swing lever 8 .

The elastic force exerted by the second torsion spring rotating shaft 18 on the lever 7 through the swing rod 8 is greater than the resultant force formed by the elastic force exerted by the first torsion spring rotating shaft 16 on the lever 7 and the elastic force exerted by the compression spring 524 on the connecting piece 522, Therefore, the connecting piece 522 can be slid in a direction close to the lower tooth holder 523 . Although the elastic force exerted by the second torsion spring shaft 18 on the lever 7 is large enough, since the end of the first swing lever arm 801 abuts against the housing 6, the end of the first lever arm 701 cannot move further away from the case The direction of the body 6 is rotated, so as to ensure that the connecting piece 522 is in a position where it is disengaged from the upper tooth sleeve 521 and has not yet been matched with the lower tooth seat 523 . In this case, the pulsator washing machine 100 is in the hand washing mode in which the inner tub 3 and the pulsator 4 rotate in opposite directions.

As shown in FIG. 7A, when the lever 7 is in the third position, the end of the first lever arm 701 is further separated from the housing 6 to the maximum extent, and the end of the second lever arm 702 abuts against the flange 5223, and Under the action of the second external force, the connecting piece 522 is pressed to slide in a direction close to the lower tooth holder 523 until it cooperates with the lower tooth holder 523 . The aforementioned second external force will be introduced later.

As shown in FIG. 7B , the external force acting on the swing rod 8 disappears at this time, and the swing rod 8 is at the first swing position under the action of the second torsion spring rotating shaft 18 , that is, the end of the first swing rod arm 801 and the housing 6 abuts, and the end of the second rocker arm 802 is away from the housing 6 . However, at this time, the side limiting rib 71 of the lever 7 does not abut against the end of the second swing lever arm 802 , but rotates further away from the housing 6 . In this case, the pulsator washing machine 100 is in the pulsator washing mode where the inner tub 3 is locked and only the pulsator 4 rotates.

As shown in FIGS. 5A to 5C , FIGS. 6A to 6B and FIGS. 7A to 7B , the pulsator washing machine 100 further includes a limit rod 17 and a connecting end of the limit rod 17 and connected to the connecting end of the limit rod 17 . The third torsion spring shaft 20 .

The third torsion spring shaft 20 is used to apply an elastic force to the limit rod 17 to drive the limit rod 17 to rotate toward the swing rod 8 . The third torsion spring rotating shaft 20 includes a third rotating shaft and a third torsion spring sleeved on the third rotating shaft. After the limit rod 17 is installed on the swing rod 8 through the third torsion spring shaft 20 , the third torsion spring is elastically deformed, thereby forcing the free end of the limit rod 17 to rotate toward the swing rod 8 .

The limit rod 17 rotates synchronously with the swing rod 8 . There is an included angle between the limit lever 17 and the second swing lever arm 802 of the swing lever 8 , and the end of the first lever arm 701 of the lever 7 is placed on the limit lever 17 and the second swing lever arm 802 of the swing lever 8 between.

When the lever 7 is in the first position, as shown in FIG. 5C , the free end of the limiting lever 17 abuts against the lever 7 . For example, the free end of the limit rod 17 abuts against the side limit rib of the shift rod 7 . As can be seen from the foregoing, when the lever 7 is in the first position, the end of the first lever arm 701 abuts against the housing 6 under the action of the first torsion spring shaft 16, and the end of the second lever arm 702 is in contact with the flange 5223 separated to the maximum extent. If the free end of the limit lever 17 is abutted against the lever 7, a driving force can be applied to the end of the first lever arm 701 to rotate it in the direction close to the housing 6, so that the lever 7 can be maintained at the first lever 701. reliability of a location. For example, when the pulsator washing machine 100 vibrates during washing or dehydration, the lever 7 will not be disengaged from the first position.

In addition, during the movement of the lever 7 from the second position to the first position, the free end of the limit lever 17 can always abut against the lever 7 to push the first lever arm 701 toward the direction close to the housing 6 turn. But it is not limited to this, when the lever 7 is in the first position, the free end of the limiting lever 17 may not abut against the lever 7 .

When the lever 7 is in the second position, as shown in FIG. 6B , the limit lever 17 rotates synchronously with the swing lever 8 , so that the free end of the limit lever 17 is separated from the lever 7 .

When the lever 7 is in the third position, as shown in FIG. 7B , the end of the first lever arm 701 is further separated from the housing 6 under the action of the aforementioned second external force until it abuts against the free end of the limit lever 17 . The elastic force exerted by the third torsion spring on the limit rod 17 can be greater than the aforementioned second external force, so that the end of the first lever arm 701 can no longer continue to move toward the limit rod 17 after it abuts against the free end of the limit rod 17 . Rotate away from the housing 6, so that the lever 7 stays in the third position.

However, it is not necessary to use the limit lever 17 to make the lever 7 stay at the third position accurately. This is because when the lever 7 is in the third position, the end of the second lever arm 702 abuts against the flange 5223, and under the action of the second external force, the connecting piece 522 is forced to slide and fit with the lower tooth holder 523, and even after that Continue to apply the second external force to the lever 7 , and the connecting piece 522 will not continue to slide in the direction close to the lower tooth holder 523 . Therefore, when the second external force is large enough, the third position of the lever 7 can be positioned by the cooperation of the connecting member 522 and the lower tooth holder 523 , without the use of the limit lever 17 .

In some embodiments, when the lever 7 is in the first position, the free end of the limit lever 17 abuts against the lever 7, and when the lever 7 is in the third position, the free end of the limit lever 17 is not It abuts against the lever 7; or, when the lever 7 is in the first position, the free end of the limit lever 17 does not abut against the lever 7, and when the lever 7 is in the third position, the limit lever 17 is in the third position. The free end abuts against the lever 7; or, when the lever 7 is in the first position, the free end of the limit lever 17 abuts against the lever 7, and when the lever 7 is in the third position, the limit lever The free end of 17 is still abutting against lever 7 .

As shown in FIGS. 5C , 6B and 7B, in order to prevent the limit rod 17 from being difficult to maintain the angle between the limit rod 17 and the second swing rod arm 802 of the swing rod 8 under the driving of the third torsion spring rotating shaft 20, the limit rod 17 The limiting portion 171 is included. The limiting portion 171 abuts against the swing rod 8 , thereby restricting the rotation of the limiting rod 17 toward the swing rod 8 and ensuring the included angle between the limiting rod 17 and the second swing arm 802 of the swing rod 8 .

It should be noted that, in some embodiments, the limiting rod 17 may also be fixedly connected to the swing rod 8 and rotate synchronously with the swing rod 8 .

It can be seen from the above analysis that by arranging the lever 7 and the swing lever 8 in the pulsator washing machine 100, the swing lever 8 is used to precisely control the lever 7 to be in the first position, thereby controlling the connection piece 522 to cooperate with the upper gear sleeve 521, and then The pulsator washing machine 100 is accurately placed in the drum washing mode; or the swing lever 8 is used to precisely control the lever 7 to be in the second position, so that the connecting piece 522 is not matched with the upper tooth sleeve 521 and the lower tooth seat 523, and then control the The pulsator washing machine 100 is precisely in the hand washing mode; or the lever 7 is precisely controlled to be in the third position by the cooperation of the connecting member 522 and the lower tooth holder 523 , so as to control the pulsator washing machine 100 to be precisely in the pulsator washing mode.

It should be noted that, in some embodiments, the limit rod 17 and the third torsion spring shaft 20 may also have other implementation forms, or the limit rod 17 and the third torsion spring shaft 20 are not necessary, which will be discussed later introduced in the text.

Next, a drive device for switching the pendulum rod 8 between the first swing position and the second swing position will be described.

As shown in FIGS. 5A to 5C , FIGS. 6A to 6B and FIGS. 7A to 7B , the pulsator washing machine 100 further includes a gear control retractor 9 , a pull rope 11 , a pull block 12 , a brake lever 10 and a drive lever 19 . One end of the pull block 12 is connected with the gear control retractor 9 through the pull rope 11 , and the other end is connected with the brake lever 10 . The drive lever 19 is roughly a bolt and is fixedly connected to the brake lever 10 . One end of the brake lever 10 is connected with the pull block 12 , and the other end is connected with the brake band 13 . As shown in FIG. 8A , the pulsator washing machine 100 further includes a brake band 13 and a fourth torsion spring shaft 21 , and the brake lever 10 is connected to the housing 6 through the fourth torsion spring shaft 21 . The brake band 13 is located between the brake housing 540 and the housing 6 and surrounds the outer side of the brake housing 540 .

In some embodiments, the fourth torsion spring shaft 21 and the second torsion spring shaft 18 are the same shaft. However, it is not limited to this, and the fourth torsion spring rotating shaft 21 and the second torsion spring rotating shaft 18 may not be the same shaft.

The fourth torsion spring shaft 21 is used to apply an elastic force to the brake lever 10 to drive the brake lever 10 to rotate away from the gear control retractor 9 . The fourth torsion spring rotating shaft 21 includes a fourth rotating shaft and a fourth torsion spring sleeved on the fourth rotating shaft. After the brake lever 10 is mounted on the housing 6 through the fourth torsion spring shaft 21 , the fourth torsion spring is elastically deformed, thereby forcing the brake lever 10 to rotate away from the gear controller 9 .

The gear control retractor 9 can control the reciprocating motion of the pull block 12 through the pull rope 11 , and then control the rotation of the brake lever 10 through the reciprocating motion of the pull block 12 . Because the drive lever 19 is fixedly connected to the brake lever 10 and rotates synchronously with the brake lever 10 , the gear control retractor 9 can control the rotation of the drive lever 19 through the brake lever 10 .

In addition, since the brake lever 10 is also connected with the brake band 13 , the brake band 13 can be controlled to be tightened or loosened by the rotation of the brake lever 10 . When the brake band 13 is loosened, the brake band 13 has no braking effect on the brake housing 540 , and the brake housing 540 does not restrict the rotation of the inner tub 3 . When the brake band 13 is tightened, the brake band 13 has a braking effect on the brake housing 540, and the brake housing 540 controls the inner tub 3 to be locked so that it cannot rotate.

Using the brake band 13 can quickly tighten the brake housing 540, so that the inner tub 3 can be stopped quickly. For example, when the user opens the top plate of the pulsator washing machine during washing or drying, the brake belt 13 can drive the inner tub 3 to stop quickly, so as to avoid danger when the user touches the inner tub 3 rotating at high speed. However, it should be noted that the brake band 13 is not necessary.

In order to better control the rotation of the brake lever 10 , the pull block 12 includes a limit opening 121 . The limit opening 121 is located at one end of the pull block 12 connected with the brake lever 10 , and the end of the brake lever 10 connected with the pull block 12 is located in the limit opening 121 . In this case, the pull block 12 can better drive the brake lever 10 to rotate.

The gear control retractor 9 can control the pull block 12 in the first stroke and the second stroke. In the following, when the pull block 12 is in different strokes, the connection relationship and the motion state of the various structures of the pulsator washing machine 100 will be explained.

When the pull block 12 is in the initial position, as shown in FIG. 7B , the fourth torsion spring shaft 21 drives the brake lever 10 to rotate, and the brake lever 10 drives the pull block 12 to move to the position farthest from the gear control retractor 9 . position (ie the initial position), the drive rod 19 is separated from the pendulum rod 8 . In addition, the brake lever 10 also controls the brake band 13 to brake, and the brake band 13 is in a tensioned state, thereby preventing the brake housing 540 from rotating, thereby preventing the inner tub 3 from rotating. At this time, as shown in FIG. 7B , the swing lever 8 is in the first swing position, but the lever 7 is in the third position. By arranging the brake lever 10 and the pull block 12 in the pulsator washing machine 100, and when the pull block 12 is at the initial position, the brake belt 13 is controlled to be in a tensioned state, thereby locking the inner tub 3, and the pulsator washing machine 100 can be further ensured. Accuracy when in pulsator wash mode.

As shown in FIG. 8A , when the brake lever 10 rotates counterclockwise around the fourth torsion spring shaft 21, the brake band 13 is tightened; and when the brake lever 10 rotates clockwise around the fourth torsion spring shaft 21, the brake Take 13 to relax.

When the gear control retractor 9 drives the pull block 12 to start the first stroke, the gear control retractor 9 drives the pull block 12 to move through the pull rope 11 , and the pull block 12 drives the brake lever 10 to rotate, thereby driving the drive rod 19 to rotate , until the driving rod 19 contacts the pendulum rod 8 (at this time, the driving rod 19 just contacts the pendulum rod 8 and does not exert force on the pendulum rod 8). The first stroke ends after the driving rod 19 is in contact with the swing rod 8 (in some embodiments, when the first stroke ends, the driving rod 19 and the swing rod 8 may not be in contact). That is, in the first stroke, the driving rod 19 has no force acting on the pendulum rod 8 . As shown in FIG. 6B , the swing lever 8 is still in the first swing position under the action of the elastic force of the second torsion spring shaft 18 , the end of the first swing lever arm 801 abuts against the housing 6 , and the second swing lever arm 802 The end of the rod is far away from the housing 6 and abuts against the side limiting rib 71 of the lever 7 . When the first stroke of the pull block 12 ends, the lever 7 is in the second position, and the pulsator washing machine 100 is in the hand washing mode in which the inner tub 3 and the pulsator 4 rotate in opposite directions. At this time, the brake band 13 is in a relaxed state and has no braking effect on the brake housing 540 .

It should be noted that, when the pull block 12 is in the initial position, the pulsator washing machine 100 must be in the pulsator washing mode. However, when the pulsator washing machine 100 is in the pulsator washing mode, the pull block 12 does not necessarily have to be at the initial position, and the pull block 12 may also be at the end of the first stroke. This is because, when the pulsator washing machine 100 is in the pulsator washing mode, the inner tub 3 is kept fixed by the combination of the connecting member 522 and the lower tooth holder 523; on this basis, the brake band 13 can lock the inner tub 3, which When the pull block 12 is in the initial position; the brake band 13 can also release the inner barrel 3, and the pull block 12 is at the end of the first stroke at this time.

When the gear control retractor 9 drives the pull block 12 to start the second stroke, the gear control retractor 9 drives the pull block 12 to continue to move through the pull rope 11 , and the pull block 12 drives the brake lever 10 to continue to rotate, so that the drive rod 19 The swing rod 8 is driven to rotate against the elastic force of the second torsion spring rotating shaft 18 , so that the swing rod 8 is in the second swing position. That is, as shown in FIG. 5C , the end of the first swing lever arm 801 is separated from the casing 6 , and the end of the second swing lever arm 802 is at the position closest to the casing 6 and is in contact with the side limiting rib 71 of the lever 7 . separation. When the pull block 12 reaches the end of the second stroke, the lever 7 is rotated to the first position, and the pulsator washing machine 100 is in the drum washing mode in which the inner tub 3 and the pulsator 4 rotate in the same direction. At this time, the brake band 13 is in a relaxed state and has no braking effect on the brake housing 540 .

During the first stroke and the second stroke of the pull block 12, the pull block 12 drives the brake lever 10 to rotate, the brake lever 10 drives the drive rod 19 to rotate, and the drive rod 19 controls the swing rod 8 to swing, thereby controlling the swing rod 8 Switch between the first swing position and the second swing position. The swing of the pendulum lever 8 can control the toggle lever 7 to be in the first position or the second position, thereby realizing the precise selection of the rotary tub washing mode or the hand scrubbing washing mode of the pulsator washing machine 100 . In addition, when the pull block 12 is in the initial position, the brake lever 10 rotates under the action of the fourth torsion spring rotating shaft 21, so that the brake lever 10 controls the braking of the brake band 13, and the brake band 13 is in a tensioned state, thereby The inner tub 3 is further locked, thereby realizing precise selection of the pulsator washing mode of the pulsator washing machine 100 .

It should be noted that, in some embodiments, the driving device for switching the pendulum rod 8 between the first swing position and the second swing position may also have other implementation forms.

As mentioned above, when the lever 7 is in the third position, the end of the first lever arm 701 is further separated from the housing 6 to the maximum extent, and the end of the second lever arm 702 abuts against the flange 5223, and is in the Under the action of the second external force, the connecting piece 522 is forced to slide in a direction close to the lower tooth holder 523 until it cooperates with the lower tooth holder 523 . As shown in FIGS. 5A to 5C , FIGS. 6A to 6B and FIGS. 7A to 7B , the pulsator washing machine 100 further includes a washing tractor 14 and a tension spring 15 to provide the second external force to the lever 7 .

The washing retractor 14 is connected to the end of the first lever arm 701 of the lever 7 through the tension spring 15 , and drives the lever 7 to rotate through the tension spring 15 , thereby controlling the position change of the lever 7 .

The washing retractor 14 can drive the tension spring 15 to be in the first limit position and the second limit position. The following will explain the connection relationship and the motion state of the various structures in the pulsator washing machine 100 when the tension spring 15 is in the first limit position and the second limit position respectively.

When the washing retractor 14 drives the tension spring 15 to run to the first limit position, the tension spring 15 can be in a compressed state or an original length state, and the lever 7 can be in the first position or the second position at this time.

For example, when the lever 7 is in the first position, the tension spring 15 is in a compressed state. It can be seen from the above that at this time, the gear control retractor 9 drives the swing rod 8 through the drive rod 19 to overcome the elastic force of the second torsion spring rotating shaft 18, so that the swing rod 8 is in the second swing position. The tension spring 15 in the compressed state exerts an elastic force on the end of the first lever arm 701 of the lever 7 to drive it to move in the direction close to the housing 6 , and the first torsion spring shaft 16 also applies the lever 7 to make the lever move. The force that the end of the first lever arm 701 of the lever 7 moves in the direction close to the casing 6, under the action of the above two forces, the end of the first lever arm 701 of the lever 7 moves in the direction close to the casing 6 Move until contacting the housing 6, at this time the lever 7 is in the first position, and the pulsator washing machine 100 is in the drum washing mode in which the inner tub 3 and the pulsator 4 rotate in the same direction.

In some embodiments, when the lever 7 is in the first position, the tension spring 15 may be in the original length state. In this case, the tension spring 15 has no force on the lower end of the lever 7, and only relies on the first torsion spring rotating shaft 16 to apply the end of the first lever arm 701 of the lever 7 to make it move closer to the housing 6. The force of the directional movement, so that the lever 7 is in the first position.

In other embodiments, when the lever 7 is in the first position, the tension spring 15 may also be in a stretched state. In this case, the force exerted by the first torsion spring rotating shaft 16 on the lever 7 to make the end of the first lever arm 701 of the lever 7 close to the housing 6 is greater than that exerted by the tension spring 15 in the stretched state on the lever 7 The pulling force to keep the end of the first lever arm 701 of the lever 7 away from the housing 6 .

For another example, when the lever 7 is in the second position, the tension spring 15 is in a compressed state. As can be seen from the above, at this time, the gear control retractor 9 drives the drive rod 19 to no longer contact the swing rod 8 , and the drive rod 19 has no force on the swing rod 8 . The elastic force of the second torsion spring rotating shaft 18 is greater than the force exerted by the tension spring 15 and the first torsion spring rotating shaft 16 on the end of the first shift lever arm 701 of the shift lever 7 to make it close to the housing 6 , therefore, in the second torsion spring Under the action of the elastic force of the spring rotating shaft 18, the swing rod 8 is in the first swing position, and the pulsator washing machine 100 is in the hand washing mode in which the inner tub 3 and the pulsator 4 rotate in opposite directions.

In some embodiments, when the lever 7 is in the second position, the tension spring 15 may be in the original length state. In this case, the tension spring 15 has no force on the lower end of the lever 7 , and relies on the action of the swing lever 8 to move the end of the first lever arm 701 of the lever 7 away from the housing 6 . force, so that the lever 7 is in the second position.

When the washing retractor 14 drives the tension spring 15 to run to the second limit position, the tension spring 15 can be in a tension state, and the tension spring 15 in the tension state makes the lever 7 in the third position.

One end of the pull block 12 is connected with the gear control retractor 9 through the pull rope 11 , and the other end is connected with the brake lever 10 . The drive lever 119 is fixedly connected to the brake lever 10 . One end of the brake lever 10 is connected with the pull block 12 , and the other end is connected with the brake band 13 .

5A to 5C, 6A to 6B, 7A to 7B, 9A to 9C, and 10A to 10D, the structure of the driving rod 19 is different (the driving rod is roughly similar to a bolt), as shown in Figures 12 to 14 The driving rod 119 is substantially L-shaped, its first driving arm 1191 is rotatably connected to the second torsion spring shaft 18, and the second driving arm 1192 is fixedly connected to the brake lever 10 and can abut on the swing rod 8 on the second rocker arm 802.

The gear control retractor 9 can control the reciprocating motion of the pull block 12 , and then control the rotation of the brake lever 10 through the reciprocating motion of the pull block 12 . Because the second driving arm 1192 is fixedly connected to the brake lever 10 and rotates synchronously with the brake lever 10 , the gear control retractor 9 can control the rotation of the driving lever 119 through the brake lever 10 . The rotation of the driving lever 119 can push the second swing lever arm 802 to rotate, so that the swing lever 8 is switched between the first swing position and the second swing position.

By arranging the brake lever 10 and the pull block 12 in the pulsator washing machine 100, and when the pull block 12 is at the initial position, the pulsator washing machine 100 is in the pulsator washing mode.

When the gear control retractor 9 drives the pull block 12 to start the first stroke, the gear control retractor 9 drives the pull block 12 to move, the pull block 12 drives the brake lever 10 to rotate, and then drives the drive rod 119 to rotate until the drive rod 119 is in contact with the pendulum rod 8 (at this time, the driving rod 119 is just in contact with the pendulum rod 8, and no force is applied to the pendulum rod 8). The first stroke ends after the driving rod 119 is in contact with the swing rod 8 (in some embodiments, when the first stroke ends, the driving rod 19 and the swing rod 8 may not be in contact). That is, in the first stroke, the driving rod 119 has no force acting on the pendulum rod 8 . As shown in FIG. 13 , the swing lever 8 is still in the first swing position under the action of the elastic force of the second torsion spring rotating shaft 18 , the end of the first swing lever arm 801 abuts against the housing 6 , and the second swing lever arm 802 The end of the rod is far away from the housing 6 and abuts against the side limiting rib 71 of the lever 7 . When the pull block 12 is at the end of the first stroke, the lever 7 is at the second position, and the pulsator washing machine 100 is in the hand washing mode in which the inner tub 3 and the pulsator 4 rotate in opposite directions.

When the gear control retractor 9 drives the pull block 12 to start the second stroke, the gear control retractor 9 drives the pull block 12 to continue to move, and the pull block 12 drives the brake lever 10 to continue to rotate, so that the drive rod 119 drives the swing rod 8 It rotates against the elastic force of the second torsion spring shaft 18 , so that the swing rod 8 is in the second swing position. That is, as shown in FIG. 12 , the end of the first swing lever arm 801 is separated from the casing 6 , and the end of the second swing lever arm 802 is at the position closest to the casing 6 , and is in contact with the side limiting rib 71 of the lever 7 . separation. When the pull block 12 reaches the end of the second stroke, the lever 7 is rotated to the first position, and the pulsator washing machine 100 is in the drum washing mode in which the inner tub 3 and the pulsator 4 rotate in the same direction.

During the first and second strokes of the pull block 12 , the pull block 12 drives the brake lever 10 to rotate, the brake lever 10 drives the drive rod 119 to rotate, and the drive rod 119 controls the swing rod 8 to swing, thereby controlling the swing rod 8 Switch between the first swing position and the second swing position.

As shown in FIGS. 12 to 14 , in some embodiments, the pulsator washing machine 100 does not include the limiting rod 17 and the third torsion spring rotating shaft 20 .

As shown in FIGS. 15A to 15B , FIGS. 16A to 16B and FIGS. 17A to 17B , in some embodiments, the top-loaded washing machine 100 includes a swing rod 108 and a drive rod 219 .

5A to 5C, 6A to 6B, 7A to 7B, 9A to 9C, and 10A to 10D have different structures of the swing lever 8 (the second swing lever arm 802 is located at the position of the lever 7 close to the housing 6). 15A~15B, 16A~16B and 17A~17B shown in the swing lever 108, the second swing lever arm 1082 is located on the side of the lever 7 away from the housing 6, so that the first swing lever The end of the arm 1081 can abut against the housing 6 , and the end of the second rocker arm 1082 can abut against the lever 7 .

5A to 5C, 6A to 6B, 7A to 7B, 9A to 9C, and 10A to 10D have different structures of the driving rod 19 (the driving rod is roughly similar to a bolt), and FIGS. 15A to 15B, The driving rod 219 shown in 16A to 16B and FIGS. 17A to 17B is substantially rod-shaped, and the driving rod 219 and the swing rod 108 have an integral structure.

When the pull block 12 is in the initial position, as shown in FIGS. 17A to 17B , the brake lever 10 drives the pull block 12 to move to the position farthest from the gear control retractor 9 (ie, the initial position), and the drive rod 219 is not affected The force exerted by the brake lever 10; the driving rod 219 and the pendulum rod 108 are integral structures, at this time, the pendulum rod 8 is in the first swing position, that is, the end of the first pendulum arm 1081 abuts against the housing 6, and the second The end of the swing lever arm 1802 is away from the housing 6; the lever 7 is in the third position, and the side limit ribs 71 of the lever 7 abut against the end of the second swing lever arm 1802 (in some embodiments, the side limit The end of the rib 71 and the second swing lever arm 1802 may not be in contact); the first torsion spring rotating shaft 16 has a tendency to rotate the end of the first lever arm 701 toward the direction of the housing 6; the washing tractor 14 drives The tension spring 15 runs to the second limit, the tension spring 15 is in a tension state, the tension spring 15 in the tension state overcomes the force provided by the first torsion spring shaft 16, and makes the end of the first lever arm 701 move away from the housing The rotation in the direction of the body 6 makes the lever 7 in the third position. At this time, the pulsator washing machine 100 is in the washing mode in which the inner tub 3 is locked and only the pulsator 4 rotates.

When the gear control retractor 9 drives the pull block 12 to start the first stroke, the gear control retractor 9 drives the pull block 12 to move, and the pull block 12 drives the brake lever 10 to rotate, thereby driving the drive rod 219 and the swing rod 108 together turn. As shown in FIGS. 16A to 16B , after the first stroke ends, the swing lever 108 is in a position between the first swing position and the second swing position, that is, the end of the first swing lever arm 1801 is separated from the housing 6 , the end of the second swing lever arm 1802 is close to the housing 6 but is still separated from the case 6 ; the lever 7 is in the second position, and the side limiting rib 71 of the lever 7 abuts against the end of the second swing lever arm 1802 , the second swing lever arm 1802 pushes the end of the first lever arm 701 to rotate toward the direction close to the housing 6 ; Trend; the washing retractor 14 drives the tension spring 15 to maintain the second limit position, the tension spring 15 is in a tension state, and the tension spring 15 in the tension state has the function of making the end of the first lever arm 701 move away from the housing 6 The tendency of rotation; the first torsion spring shaft 16, the tension spring 15 and the second swing lever arm 1802 work together to make the lever 7 in the second position. At this time, the pulsator washing machine 100 is in the hand washing mode in which the inner tub 3 and the pulsator 4 rotate in opposite directions.

When the gear control retractor 9 drives the pull block 12 to start the second stroke, the gear control retractor 9 drives the pull block 12 to continue to move, and the pull block 12 drives the brake lever 10 to continue to rotate, so that the drive rod 219 drives the swing rod 108 Overcoming the elastic force of the second torsion spring shaft 18 to rotate, so that the swing rod 108 is in the second swing position. 15A-15B, the end of the first swing arm 1801 is separated from the housing 6, and the end of the second swing arm 1802 and the side limiting rib 71 of the lever 7 can abut or be separated. When the pull block 12 reaches the end of the second stroke, the lever 7 rotates to the first position; the washing retractor 14 drives the tension spring 15 to keep at the first limit position, and the tension spring 15 is in a compressed state or an original length state (of course, the tension The spring 15 can also be in a stretched state, but the pulling force exerted by the tension spring 15 on the lever 7 is not enough to disengage the lever 7 from the first position). At this time, the pulsator washing machine 100 is in the drum washing mode in which the inner tub 3 and the pulsator 4 rotate in the same direction.

However, it is not limited to this, and the situations in which the washing retractor 14 drives the tension spring 15 to be in the first limit position and the second limit position may also be different. Examples are given below.

When the pull block 12 is at the initial position, the washing puller 14 drives the tension spring 15 to be at the second limit position, which is the same as the situation shown in FIGS. 17A-17B .

However, when the pull block 12 is at the end of the first stroke, the washing retractor 14 drives the tension spring 15 to maintain the first limit position instead of the second limit position, as shown in FIGS. 18A to 18B . At this time, the tension spring 15 is in the original length state. Although the first torsion spring rotating shaft 16 has a tendency to rotate the end of the first lever arm 701 toward the direction close to the housing 6, the force provided by the first torsion spring rotating shaft 16 is not enough to elastically deform the tension spring 15. And then the tension spring 15 is stretched; therefore, the first torsion spring rotating shaft 16 and the tension spring 15 work together so that the lever 7 is in the second position.

In this case, the side limiting rib 71 of the lever 7 and the end of the second swing lever arm 1802 can abut or be separated, but not necessarily abut. Therefore, when the pulsator washing machine 100 is in the pulsator washing mode, the pull block 12 does not necessarily have to be at the initial position, and the pull block 12 may also be at the end of the first stroke. 16A to 16B , when the pull block 12 is at the end of the first stroke, the side limiting rib 71 of the lever 7 must abut against the end of the second swing lever arm 1802 , then when the pulsator washing machine 100 is in the In the pulsator washing mode, the pull block 12 must be at the initial position, but not at the end of the first stroke.

When the pulling block 12 is at the end of the second stroke, the washing retractor 14 drives the tension spring 15 to maintain the first limit position, which is similar to the situation shown in FIGS. 15A to 15B . 15A to 15B , the end of the second swing lever arm 1802 and the side limiting rib 71 of the lever 7 can abut or be separated. The side limiting rib 71 abuts against, so that the second swing lever arm 1802 pushes the end of the first lever arm 701 to rotate in the direction close to the housing 6, so that the tension spring 15 is elastically deformed, that is, the tension spring 15 is pulled stretch.

As shown in FIGS. 15A-15B, FIGS. 16A-16B and FIGS. 17A-17B, in some embodiments, the top-loading washing machine 100 does not include the limiting rod 17 and the third torsion spring rotating shaft 20.
