The specific embodiment
Referring to accompanying drawing, it comprises drive unit and interior bucket, wherein drive unit comprises outer driving shaft 1 and interior driving shaft 2, outer driving shaft 1 is connected as a single entity with interior bucket, at ball bearing 4 of the top of outer driving shaft 1 suit, vibrating disk 5 in relative rotation is set on the ball bearing 4, and the top of vibrating disk 5 is provided with the locating detent 6 that is sleeved on the outer driving shaft 1 and embeds vibrating disk, and this locating detent 6 guarantees that vibrating disk 5 in ball bearing 4 vibrations axial rotation is not taking place; The top of locating detent 6 is the state transition arm 7 that are sleeved on the outer driving shaft 1.In the top of state transition arm 7 connects by interior driving shaft 2 under the actuator 8, in driving, interior drive shaft turns 8 rotates under the actuator; Under the interior actuator 8 top arrange off-axis to sleeve 81, the upper surface of this sleeve 81 is made up of two planes of height, is ladder 82,83 and changes; Sleeve 81 interior insertions under the interior actuator can be in relative rotation on the actuator 9; 9 middle part connects a pair of cantilever 91 on the interior actuator, and lower protruding block 92 is set, the stepped change of 8 upper surfaces is consistent under the thickness of this block 92 and the interior actuator, and cantilever 91 bottoms connect the ratchet 93,94 of one-directional rotation by torsion spring, and this ratchet is unidirectional by state transition arm 7; On the interior actuator 9 top one side arrange off-axis to inclined shaft 95, this inclined shaft 95 is connected with sealing cap 10 by the bearing that is embedded in the sealing cap top, sealing cap 10 is connected as a single entity with vibrating disk 5, in the bottom of ball bearing 4 sealing ring 3 is set; Have an impeller to be fixed on the vibrating disk 5, and impeller and vibrating disk 5 internally keep certain height in a bucket end mutually.
Adopt the drive unit of said structure, when washing machine is in the washing state, driving shaft 2 one-directional rotation in the driven by motor, 8 rotations under the actuator in interior driving shaft 2 drives, 9 rotations on the internal mutually actuator of the sleeve 81 of 8 upper ends under the interior actuator, after the block 92 at middle part on the ladder 83 of sleeve upper surface and the interior actuator meets, 9 in company with 8 together rotations under the interior actuator on the interior actuator, the inclination angle of 9 inclined shaft 95 relative sleeves 81 and sleeve 81 inclination angle stack to axial on the actuator in this moment, driving shaft 2 rotates like this, the inclined shaft 95 on 9 tops is around interior drive shaft turns on the interior actuator, its track is the taper of the vertex of a cone by the ball bearing center, inclined shaft 95 tops connect sealing cap 10 and vibrating disk 5 and impeller, the impeller misalignment is axial like this, make the impeller relative drive shaft form angle rotation, its each moment in one changes is not all not in one plane; In the middle of this process, the ratchet that cantilever connected 93 relative ratchets 94 on the interior actuator in 9 are downward-sloping, ratchet 93 whenever rotates a circle and then collides twice with state transition arm 7, it can overturn in this washing process by state transition arm 7, and reset, thereby the upper and lower rotation of actuator in realizing by torsion spring.Because the rotation between inclined shaft 95 and the bearing is offset, and has so just formed the vibration of vibrating disk and sealing cap one, impeller forms vibration like this, utilizes this vibration clothing to wash; This mode of washing only needs a small amount of water to carry out, and does not need clothing is flooded, thereby has saved water consumption, has also reduced wearing and tearing and winding to clothing simultaneously.
Before dewatering state begins, 8 backward rotation under the actuator in interior driving shaft 2 drives, 9 rotations on the internal mutually actuator of the sleeve 81 of 8 upper ends under the interior actuator, the ratchet 93 and the state transition arm 7 of cantilever lower end are met, but because of ratchet 93 is unidirectional upsets, therefore, this moment, ratchet 93 did not overturn; In this course, the ratchet 94 relative ratchets 93 under the cantilever are downward-sloping, and ratchet 94 meets with state transition arm 7, and this ratchet can unidirectional upset pass through state transition arm 7, and resets by torsion spring; After the block 92 at middle part on the ladder 82 of sleeve upper surface and the interior actuator meets, interior actuator rotates up and down and stops, cancel out each other in the inclination angle and sleeve 81 inclination angle to axial of the inclined shaft 95 relative sleeves 81 in this moment on the actuator, internally driving shaft 2 is coaxial mutually for inclined shaft 95 on the interior actuator, after the dehydration beginning, the reverse rotation of driven by motor outer driving shaft, at this moment outer driving shaft, interior driving shaft, impeller and interior bucket backward rotation together realizes dehydration.
