With reference to fig. 3, the second driving mechanism includes a second clutch 42 disposed on the extending shaft at the other end of the dual-shaft extending motor 4, a first gear 91 connected to the extending shaft at the other end of the dual-shaft extending motor 4, a second gear 92 engaged with the first gear 91, a third gear 93 engaged with the first gear 91, a second roller 62 connected to the second inner cylinder 22 in a transmission manner, a third roller 63 connected to the third inner cylinder 23 in a transmission manner, a second pull rope 72, a third pull rope 73, a first spring 81 and a second spring 82, the second roller 62 has a first ring groove, the third roller 63 has a second ring groove, a first rotating rod 911 is fixed on the end surface of the first gear 91, a first collar 912 is rotatably disposed at the outer end of the first rotating rod 911, a second rotating rod 921 is fixed on the end surface of the second gear 92, a second collar 922 is rotatably disposed at the outer end of the second rotating rod 921, a third rotating rod 931 is fixed on the end surface of the third gear 93, the outer end of the third rotating rod 931 is rotatably provided with a third collar 932, when the first gear 91, the second gear 92 and the third gear 93 are in a mutually meshed state, the rotation state of the first rotating rod 911 is different by 180 degrees from that of the second rotating rod 921 and the third rotating rod 931, one end of the second pulling rope 72 is connected to the first collar 912, the second pulling rope 72 is embedded in the first annular groove of the second roller 62, the other end of the second pulling rope 72 is connected to one end of the first spring 81, the other end of the first spring 81 is connected to the second collar 922, one end of the third pulling rope 73 is connected to the first collar 912, the third pulling rope 73 is embedded in the second annular groove of the third roller 63, the other end of the third pulling rope 73 is connected to one end of the second spring 82, and the other end of the second spring 82 is connected to the third collar 932.

Further, because the first rotating rod 911, the second rotating rod 921 and the third rotating rod 931 rotate synchronously in the washing process of the second inner barrel 22 and the third inner barrel 23, and the rotating states of the second rotating rod 921 and the third rotating rod 931 are different from the rotating state of the first rotating rod 911 by 180 degrees, the deformation of the first spring 81 and the second spring 82 is relatively small, the service life of the springs is prolonged, the number of times of spring replacement is reduced, and the probability of failure occurrence of the washing machine is reduced. Meanwhile, the first spring 81 and the second spring 82 of the present invention not only generate friction between the second roller 62 and the second pull rope 72 and between the third roller 63 and the third pull rope 73 to provide torque for the rotation of the second inner cylinder 22 and the third inner cylinder 23, but also compensate the speed difference generated by the second rotating rod 921 and the first rotating rod 911 at the end of the second pull rope 72, the third rotating rod 931 and the first rotating rod 911 at the end of the third pull rope 73, so that the roller can run more smoothly.

In addition, the outer walls of the first outer cylinder 31, the second outer cylinder 32 and the third outer cylinder 33 are respectively provided with a damping spring in transmission connection with the machine shell 1, so as to provide a buffering effect for the vibration generated by the drum in the washing process.

The invention can drive the three rollers to work as required by only using one double-shaft extension motor 4. When the clothes to be cleaned are less, in order to save water and electricity resources, only one roller with relatively small washing capacity is needed for washing, at the moment, the first clutch 41 works, the second clutch 42 is separated, the double-shaft extension motor 4 only can drive the first driving mechanism to operate and cannot drive the second driving mechanism to operate when rotating, in the washing process, the double-shaft extension motor 4 drives the oscillating bar 51 to swing through the crank 52 and the sliding block 53, the first roller 61 is driven to roll back and forth, the reciprocating rotation of the first inner barrel 21 is realized, and the rotating angle range of the first roller 61 can exceed 360 degrees in the clockwise or anticlockwise rotating process, as shown in fig. 2.

When more clothes are washed, and part of the clothes need to be classified and cleaned, at the moment, the first clutch is separated 41, the second clutch 42 works, the double-shaft stretching motor 4 drives the second driving mechanism to move and cannot drive the first driving mechanism to work, the double-shaft stretching motor 4 drives the first gear 91 to rotate at a constant speed, the first gear 91 simultaneously drives the second gear 92 and the third gear 93 to synchronously rotate, the second pull rope 72 and the first spring 81 drive the second roller 62 to rotate back and forth, the third pull rope 73 and the second spring 82 drive the third roller 63 to rotate back and forth, and similarly, the second roller 61 realizes the work of the second roller, the third roller 63 realizes the work of the third roller, the continuous rotation of one gear simultaneously drives the back and forth alternate rotation of the two rollers, and the synchronous washing work of the two rollers of the washing machine is completed.

When more clothes are washed and three rollers are required to work synchronously, only two clutches are required to work simultaneously, the specific working modes of the three rollers are the same, and the three rollers are not redundant.

The invention adds three drums with different specifications on the same drum washing machine, when the clothes to be washed are more, the two clutches can work simultaneously, at the moment, the three drums work simultaneously, the washing capacity of the washing machine is increased, the classified washing of the clothes is realized, when the clothes to be washed are less, the first clutch 41 works, the second clutch 42 is separated, at the moment, only one drum with relatively smaller washing amount works; when the number of the laundry is relatively general and the sorting and washing are required at the same time, the first clutch 41 is disengaged and the second clutch 42 is operated, and at this time, the two drums having different specifications are washed.
