Dynamic lower synchronous rotation；When 120 ° of electrical angles are not turned on, middle cylinder 32 and inner cylinder 31 stop operating.Meanwhile first primary coil
22 are not turned on first grade induction part 42 in entire electrical angle (360 ° of electrical angles) range, thus the second primary coil 23 with
43 centering cylinder 32 of second subprime induction part does not generate torque, but under the magneticaction of the two, and middle cylinder 32 and inner cylinder 31 are in outstanding
Floating state, realizes suspension support.
In this way, in the present embodiment, the rotation mutual induction of primary coil 20 and secondary induction portion 40 cooperates.
When interior cartridge module rotates, one end is driven, and the other end is by magnetic support.
In the present embodiment, the first rotation direction is that clockwise, the second rotation direction is counterclockwise.
In the present embodiment, the type of drive of each primary coil 20 of bi-directional magnetic suspension driving drives for one direction,
120 ° of electrical angles are not turned on.Therefore, the torque direction of interior cartridge module will not occur inversely to change, to realize interior cartridge module
Stable rotation.In this way, the type of drive of washing machine is bi-directional drive mode, motor positive and inverse is handed over when to solve unidirectional drive
Energy consumption when changing.
It can be seen from the above description that the above embodiments of the present invention achieve the following technical effects：
When needing washing drum mechanism to run, it is powered, is then generated between primary coil and secondary induction portion to primary coil
Magnetic force, so that interior cartridge module can be pivoted relative to outer barrel.Meanwhile washings can be by between inner cylinder and middle cylinder
Ebb interval outflow is crossed, the washing to complete washing drum mechanism acts.
Compared with the fixed form for using bearing support inner cylinder in the prior art, the washing drum mechanism in the application uses magnetic
Suspension support mode is supported interior cartridge module, eliminates bearing arrangement, avoids since the eccentric rotary of inner cylinder leads to axis
The phenomenon that holding generation vibration and noise occurs, and thereby reduces the vibration and noise that washing drum mechanism generates in the process of running,
It improves the user experience.Meanwhile the washing drum mechanism in the application ensures that interior cartridge module will not be in direct contact with outer barrel, in turn
Reduce structural wear between the two, extends the service life of washing drum mechanism.
