Description of drawings
Fig. 1 is the structure chart of existing nutating washing machine.
Fig. 2 is the structure chart of the embodiment one of magnetic suspension type vibration rotating rotary drum washing machine of the present invention.
Fig. 3 is the structure chart of the embodiment two of magnetic suspension type vibration rotating rotary drum washing machine of the present invention.
The specific embodiment
It shown in Fig. 2,3 structure chart of two kinds of embodiment of magnetic suspension type vibration rotating rotary drum washing machine of the present invention, the present invention makes impeller or oscillating deck nutating in impeller rotation washing time of utilizing magnetic field force to be implemented in rotary drum washing machine, thereby be implemented in rotary water current simultaneously, be aided with current up and down, reach better clean result; Effectively prevent to twine, wash more even; Utilize magnetic suspension force to reduce the noise that mechanical device produced.Its primary structure is: agitation wheel for washing machine 3 is linked to each other with interior axle by a universal joint 7, make impeller 3 can with interior non-coaxial rotation;
If a rotation magnet ring 8, the axis and impeller 3 axes intersect of this rotation magnet ring 8, and in interior axle 9 connections;
One nutating magnet ring 5, the axis of this nutating magnet ring 5 and impeller dead in line, the magnetic pole strength of the magnetic pole strength of this nutating magnet ring 5 and this rotation magnet ring 8 is to right, polar repulsion.
When 5 rotations of rotation magnet ring, because the polar repulsion of rotation magnet ring 5 and nutating magnet ring 8 will cause one of them swing, i.e. nutating.
Embodiment one
Shown in Figure 2 is the structure chart of the embodiment one of magnetic suspension type vibration rotating rotary drum washing machine of the present invention, comprise outer bucket 1, interior bucket 2, impeller 3, connect in bucket hollow sleeve axle 10 with is connected impeller with interior 9 of the coaxial setting of hollow sleeve axle, impeller 3 links to each other with interior axle by a universal joint 7, be provided with in these impeller 3 back sides-annular rotation magnet ring 8, in the inner face at the bucket end 4 of bucket 2, with respect to the position of rotation magnet ring 8 be provided with one with the annular nutating magnet ring 5 that repels each other of rotation magnet ring 8.The axis of this rotation magnet ring 8 and the axes intersect of impeller 3, and intersection point is positioned on the lower surface of rotation magnet ring; In the inner face of interior bucket 2, the axis of this nutating magnet ring 5 and the dead in line of interior bucket.Be connected with universal joint 7 between impeller 3 and the interior axle 9.During impeller 3 rotations, because rotation magnet ring 8 repels each other with nutating magnet ring 5 magnetic force, distance between the relative anchor ring of two magnet rings is remained unchanged, promptly the relative anchor ring of two magnet rings is parallel, because the axis of the rotation magnet ring 8 of rotation and the axes intersect of impeller 3, the parallel result of the relative anchor ring of two magnet rings then is the impeller axis and the interior bucket axes intersect of rotation, goes back side-sway (nutating) up and down when impeller rotates thereby be implemented in.From any point at interior barrel the bucket end, impeller is in rotary course, and impeller is the SIN function of the anglec of rotation to the vertical height h of this point.
h＝
1/
2H?sinωt
Wherein: H is a maximum vertical height;
ω is the angular speed of impeller with respect to interior bucket rotation.
The angle value that the axis of rotation magnet ring 8 and the axes intersect of impeller 3 intersect directly influences impeller 3 side-sway amplitudes.This angle value can be between 5 °～20 °, and the best is 15 °.
As utilization " hand-rubbing type " washing technology, the 3 rotation whiles of impeller, interior bucket 4 is rotation simultaneously also, thereby realizes that impeller 3 swings are more frequent, thereby reaches better antiwind effect, reaches better laundry effect.
For anti-sealing enters universal joint, also be provided with a sealed chamber 6 in the bottom of impeller, this universal joint 7 is sealed in the sealed chamber 6, uses grease lubrication in the universal joint tie point.
This rotation magnet ring and this nutating magnet ring of being located at interior bucket inner face of being located at the impeller back side is annular permanent-magnet steel.In the present embodiment, the axis of this nutating magnet ring and the dead in line of interior bucket or crossing.
Embodiment two
Shown in Figure 3 is the structure chart of the embodiment two of magnetic suspension type vibration rotating rotary drum washing machine of the present invention, is with the difference of embodiment one: this rotation magnet ring 8 be located at impeller 3 below, fixing by a flange 10 with interior axle; This nutating magnet ring 5 be located at an oscillating deck 11 below, this oscillating deck 11 is arranged on the universal joint 7 that connects impeller by bearing 12 and this impeller are coaxial.When interior axle 9 drives impellers 3 with the 8 synchronous rotations of rotation magnet ring, because the magnetic pole strength of the magnetic pole strength of this nutating magnet ring 5 and this rotation magnet ring 8 is to right, polar repulsion, distance between the relative anchor ring of two magnet rings is remained unchanged, promptly the relative anchor ring of two magnet rings is parallel, because then being oscillating decks 11, the axis of the rotation magnet ring 8 of rotation and the axes intersect of impeller 3, the parallel result of the relative anchor ring of two magnet rings produce side-sway (nutating) up and down.In the impeller rotary course, from any point at interior barrel the bucket end, oscillating deck 11 is the SIN function of the anglec of rotation to the vertical height h of this point.
This oscillating deck 11 is to connect with this universal joint 7 by duplex bearing.The center of this oscillating deck 11 is provided with a sealed chamber 13, and this duplex bearing and this universal joint are sealed in this sealed chamber, and are full of lubricant grease in this sealed chamber.
