In shell 110.
In a preferred embodiment, the washing drum that inner cylinder 130 and outer barrel 120 are constituted can resistance trimming by 4
Buddhist nun's suspension rod 10 hangs up, and the angle of neighboring tunable damping suspension rod 10 projection in the horizontal direction is 90 degree.
I.e. 4 adjustable damping suspension rods 10 make 4 adjustable damping suspension rods along the even circumferential radial distribution of outer barrel 120
10 uniform stresseds.
In some embodiments of the invention, rotating mechanism 800 may include motor, with planetary gear and
The transmission mechanism of sun gear, motor drives the impeller in inner cylinder 130 and inner cylinder 130 by transmission mechanism
Rotated along identical or opposite direction.
When the outer barrel of rotary drum washing machine 100 occurs radially to shake, sleeve 2 can be along the axial direction in suspension rod portion 1
Move back and forth, so that relative displacement of the permanent magnet with magnet coil in axial direction changes.At some
In embodiment, sensor (not shown) can be set on outer barrel, by the Vibration Condition for detecting outer barrel
To calculate permanent magnet and magnet coil relative displacement in axial direction in adjustable damping suspension rod 10, so that
Corresponding electric current is supplied to the magnet coil of adjustable damping suspension rod 10.In certain embodiments, also dependent on
The electric current of the magnet coil of the tach signal control adjustable damping suspension rod 10 of motor feedback, so that it is produced
The damping force of raw matching.In an alternative embodiment, also by sensor sleeve 2 can be detected along suspension rod portion 1
The relative displacement of axial direction, corresponding electric current is supplied to the magnet coil of adjustable damping suspension rod 10.So as to profit
The purpose that real-time adjustment is damped is played with the size and Orientation of magnetive attraction between magnet coil and permanent magnet.
In a further embodiment, with continued reference to Fig. 3, washing machine 100 also includes the first permanent magnet 510
With the second permanent magnet 520.First permanent magnet 510 is arranged at the bottom wall outer of inner cylinder 130；Second permanent magnet
520 inside bottom walls for being arranged at outer barrel 120, and be oppositely arranged with the first permanent magnet 510.Second permanent magnet
520 is identical with the magnetic on the relative surface of the first permanent magnet 510, with using the second permanent magnet 520 and the
Magnetic repulsion force between one permanent magnet 510 makes inner cylinder 130 be supported in outer barrel 120.That is, first
Permanent magnet 510 is suspended on the second permanent magnet 520 by it with the magnetic repulsion force of the second permanent magnet 520,
Under magnetic repulsion force effect between the first permanent magnet 510 and the second permanent magnet 520, the first permanent magnet 510
Upward support force can be produced to inner cylinder 130 by inner cylinder bottom wall, so as to overcome inner cylinder 130 gravity of itself
With the gravity of its interior contents inner cylinder 130 is suspended be supported in outer barrel 120, so as in 130 turns of inner cylinder
Do not contacted with outer barrel 120 when dynamic, it is to avoid produce mechanical friction between inner cylinder 130 and outer barrel 120, so as to have
Play to effect the effect of vibration and noise reducing.The wherein gravity of inner cylinder 130 itself and the gravity of Qi Nei contents can lead to
Cross the first permanent magnet 510 and the second permanent magnet 520 is acted directly on outer barrel bottom wall.Washing machine 100 above
Also referred to as magnetic suspension washing machine.
Between the first magnetic part 3 and the second magnetic part 5 that the present invention passes through adjustable damping suspension rod 10
Magnetic force reduces the radial vibration amplitude of outer barrel 120 (buffering the radial vibration of outer barrel 120 in other words)；By dividing
First permanent magnet 510 and the second permanent magnet 520 are not set directly or indirectly on inner cylinder 130 and outer barrel 120
(hereinafter referred to as going up lower magnet), to provide support force as inner cylinder 130 by the repulsion between upper lower magnet.
It was found by the inventors of the present invention that for magnetic suspension washing machine, because it is relied between upper lower magnet
Repulsion inner cylinder 130 is suspended on outer barrel 120, so as to cause inner cylinder 130 high speed rotate when lose
Radial constraint, so as to be susceptible to radially rock.
The present invention can alleviate the radial vibration of outer barrel 120 and then alleviate inner cylinder by setting adjustable damping suspension rod 10
130 radial vibrations.From this, adjustable damping suspension rod 10 of the invention is particularly suitable for applications in magnetcisuspension floating washing
In clothing machine.Upper lower magnet and adjustable damping suspension rod 10 are combined to form organic whole by the present invention, both can be real
Now axial Vibrant buffer can realize the vibration constraint of radial direction again, be imitated with unexpected excellent damping
Really.It will be appreciated by those skilled in the art that reducing the radial vibration of outer barrel 120 using adjustable damping suspension rod 10
The technical scheme of amplitude be applicable not only to magnetic suspension washing machine, be equally applicable to other upright type washing machines, example
Such as the washing machine of traditional bearing transmission.
So far, although those skilled in the art will appreciate that herein it is detailed have shown and described it is of the invention
Multiple exemplary embodiments, but, without departing from the spirit and scope of the present invention, still can be according to this
Disclosure of invention directly determines or derives many other variations or modifications for meeting the principle of the invention.Cause
