Magnetic is generated between grade coil 22 and first grade induction part 42 and between the second primary coil 23 and second subprime induction part 43
Power.
When washing machine is needed to be rotated forward, the first primary coil 22 and first grade induction part 42 are in an electrical cycle
In (electrical angle), 240 ° of electrical angle forward conductions, 120 ° of electrical angles are not turned on, then in 240 ° of electrical angle forward conductions, middle cylinder
32 along the first rotation direction constant revolution, and inner cylinder 31 rotates synchronously under the drive of middle cylinder 32；It is not turned in 120 ° of electrical angles
When, middle cylinder 32 and inner cylinder 31 stop operating.Meanwhile second primary coil 23 with second subprime induction part 43 in entire electrical angle
It is not turned in the range of (360 ° of electrical angles), therefore the second primary coil 23 is not generated with 43 centering cylinder 32 of second subprime induction part and turned
Square, but under the magneticaction of the two, middle cylinder 32 and inner cylinder 31 are in suspended state, realize suspension support.
When washing machine is needed to be inverted, the first primary coil 22 and first grade induction part 42 are in an electrical cycle
In (electrical angle), 240 ° of electrical angle reverse-conductings, 120 ° of electrical angles are not turned on, then in 240 ° of electrical angle reverse-conductings, middle cylinder
32 along the second rotation direction constant revolution, and inner cylinder 31 rotates synchronously under the drive of middle cylinder 32；It is not turned in 120 ° of electrical angles
When, middle cylinder 32 and inner cylinder 31 stop operating.Meanwhile second primary coil 23 with second subprime induction part 43 in entire electrical angle
It is not turned in the range of (360 ° of electrical angles), therefore the second primary coil 23 is not generated with 43 centering cylinder 32 of second subprime induction part and turned
Square, but under the magneticaction of the two, middle cylinder 32 and inner cylinder 31 are in suspended state, realize suspension support.
It should be noted that realize that the mode of washing machine return motion is without being limited thereto.Optionally, the second primary coil 23 is made
With second subprime induction part 43 in an electrical cycle (electrical angle), 240 ° of electrical angle reverse-conductings, 120 ° of electrical angles are not led

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 the range of entire electrical angle (360 ° of electrical angles), 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, middle cylinder 32 and inner cylinder 31 are in outstanding
Floating state, realizes suspension support.
In this way, in the present embodiment, primary coil 20 and the rotation mutual induction in secondary induction portion 40 cooperate.
When interior cartridge module rotates, its one end is driven, and the other end is by magnetic support.
In the present embodiment, the first rotation direction is 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, so as to fulfill 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 during so as to solve unidirectional drive
Energy consumption when changing.
It can be seen from the above description that the above embodiments of the present invention realize following technique effect：
When washing drum mechanism is needed 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 compared with outer barrel.Meanwhile washings can be by between inner cylinder and middle cylinder
Ebb interval outflow is crossed, to complete the washing of washing drum mechanism action.
Compared with using the fixed form of bearings 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 causes axis
