With reference to Fig. 1 and Fig. 2, the present embodiment provides a kind of washing machine, including inner core 102, outer tube 101 and magnetic bearing, magnetic
Power bearing includes internal axle sleeve 107, outer shaft 108 and the ball circle 115 being disposed there between, and internal axle sleeve 107 one end connects interior
The cylinder 102 and other end is provided with the first magnet 105, the first magnet 105 lower section setting is magnetic the second magnet 106 repelling each other, and leads to
Inner core 102 is suspended in outer tube 101 repulsion crossing two magnets.
Inner core 102 is suspended in outer tube 101 by the repulsion between two magnets, make inner core 102 when rotated with outer tube 101
Almost there is no Mechanical Contact, thus effectively reducing friction, reducing noise.
Additionally, the friction between internal axle sleeve 107 and outer shaft 108 can be reduced by ball circle 115 1 aspect, on the other hand
The two can be kept concentric.
One end of internal axle sleeve 107 is fixedly connected the inner core 102 bottom center of circle, and for supporting inner core 102, the other end passes through outer tube
101, internal axle sleeve 107 1 aspect is used for supporting inner core 102, and on the other hand inner core 102 is carried out with spacing guarantee inner core 102 and outer tube
101 is concentric.
Inner core 102, outer tube 101 and magnetic bearing are to be coaxially disposed.
First magnet 105 is fixed in internal axle sleeve 107；First magnet 105 relies on the repulsion and between the second magnet 106 to suspend
On the second magnet 106, the first magnet 105 drives inner core 102 to be suspended in outer tube 101 through internal axle sleeve 107.
As a kind of optional embodiment, the second magnet 106 is provided with fixed plate 114, is used for fixing the second magnet
106, prevent because the repulsion between the first magnet 105 and the second magnet 106 is excessive and lead to the second magnet 106 to overturn.
Outer shaft 108 upper end open, openend is connected with outer tube 101 bottom external stability, and outer shaft 108 inner bottom part is arranged
Second magnet 106；Internal axle sleeve 107 lower ending opening is simultaneously fixedly connected with the first magnet 105, the first magnet 105 and the second magnet 106
The polarity of opposite face is identical, according to homopolar-repulsion principle, produces repulsion between the first magnet 105 and the second magnet 106, makes the
One magnet 105 is suspended on the second magnet 106, because the first magnet 105 is solid with the internal axle sleeve 107 being fixed on inner core 102
Fixed connection, the therefore first magnet 105 can drive inner core 102 to be suspended in outer tube 101.
As a kind of optional embodiment, the first magnet 105 and/or the second magnet 106 are permanent-magnetic clamp.
As a kind of optional embodiment, magnetic bearing also include being arranged on the first magnet 105 and outer tube 101 bottom it
Between limiting component 103.
As a kind of optional embodiment, limiting component 103 is arranged on internal axle sleeve 107, specifically, limiting component
103 are located between internal axle sleeve 107 and outer tube 101 bottom and are fixed on internal axle sleeve 107, when the first magnet 105 and the second magnet
When repulsion between 106 is excessive, inner core 102 ascensional range can be limited excessive.
As a kind of optional embodiment, limiting component 103 is the blowout patche being set on internal axle sleeve 107.
Internal axle sleeve 107 is hollow structure, and the first magnet 105 and the second magnet 106 are loop configuration, in internal axle sleeve 107
Empty part is provided with impeller shafts 109, and one end of impeller shafts 109 passes through inner core 102 center of circle coaxially connected with impeller 110, impeller shafts
109 other end passes through the first magnet 105 and the ring heart of the second magnet 106 and outer shaft 107 to connect outside motor 111,
Motor 111 is used for driving impeller 110 to rotate by impeller shafts 109.
On the other hand, in extreme circumstances, between due to two magnets, the excessive inner core 102 leading to of repulsion rises and impeller 110
Contact, if inner core 102 contacts with impeller 110, can produce larger friction, limit inner core 102 by limiting component 103 and rise
Amplitude is excessive, such that it is able to avoid inner core 102 to contact with impeller 110, thus avoiding producing friction.
As a kind of optional embodiment, between outer shaft 108 and internal axle sleeve 107, it is additionally provided with above limiting component 103
First end cap 112, the first end cap 112 and the cooperation of internal axle sleeve 107 gap, for internal axle sleeve 107 is carried out spacing it is ensured that internal axle sleeve
107 is concentric with outer shaft 108.
As a kind of optional embodiment, between outer shaft 108 and the second magnet 106, it is additionally provided with the second end cap 113, use
Spacing in being fixed to the second magnet 106.
First magnet 104 and the second magnet 105 adopt permanent-magnet material, preferably neodymium-iron-boron, so that inner core 102 is always maintained at
Suspended state, internal axle sleeve 107 is all made using NULL with outer shaft 108, effectively can isolate magnetic field, makes washing machine extraneous
Article do not affected by this magnetic field.
The washing machine that the present invention provides, makes inner core suspend by the repulsive force that magnet homopolar-repulsion produces, when inner core rotates
Almost there is no a Mechanical Contact and outer tube between, reduce rocking of outer tube, additionally by ball circle reduce internal axle sleeve and outer shaft it
Between friction, further reduce noise.
