Description
Technical field
The present invention relates to a kind of drive unit, especially a kind of dual-rotor direct drive motor with speed-changing gear box.
Background technology
The rotation of its impeller of traditional rotary drum washing machine and interior bucket is that motor drives belt that power is passed to speed-reducing clutch by belt pulley, speed-reducing clutch is by the gear structure of its inside, the high rotating speed of motor is changed into the comparatively slow-speed of revolution needed in the different washing process of washing machine, simultaneously according to different mode of washing, speed-reducing clutch uses different gear structures, passes to the different rotation direction of impeller and rotation formula.
In this structure, because speed-reducing clutch and motor are horizontally arranged in outer barrel bottom, make whole system structure comparison huge.On the other hand, speed-reducing clutch is positioned at the centre of outer barrel, and motor departs from the position in centre, the centre bore of the misalignment outer barrel of outer barrel bottom total.In the washing machine course of work, while the work of driven by motor speed-reducing clutch, in rotation process own, relative outer barrel center produces a moment, adds the unsteadiness of whole system, and the noise that washing machine produces in washing process is all larger with vibration.
In order to reduce the noise and oscillation phenomenon that produce in the washing machine course of work, existing a lot of washing machine adopts direct driving motor, remove pulley belt device, the direct longitudinal installation of speed-reducing clutch is connected on motor, and the center of gravity of such outer barrel bottom structure is substantially in the position of the rotation center hold of outer barrel.This structure, improves transmission efficiency and the stability of motor, reduces the noise in running simultaneously.
But in the structure after existing change direct driving motor, because direct driving motor rotating speed is large, usual speed-reducing clutch is all equipped with intermediate gear structure.Because structure comparison is huge, aspect ratio is larger in the vertical to make whole system.Therefore whole noise result and vibrating effect are not also too desirable.
Application number be 00120729.6 Chinese patent disclose a kind of power directly-driving device for washing machine and comprise: disc type buncher; Wash shaft and motor output shaft; Rotationally supported dehydrating shaft in wash shaft; Electric motor built-in electromagnetic clutch, it is fixed with wash shaft and dehydrating shaft respectively; Electric motor built-in electricity loss brake, itself and dehydrating shaft are fixed.Motor power through electromagnetic clutch switching Direct driver wash shaft and pass to wash shaft and dehydrating shaft simultaneously.This structure adopt electric motor built-in electromagnetic clutch complex structure, cost is high and useful life is shorter.
Application number be 00120729.6 Chinese patent disclose a kind of washing machine of direct driving type clutch, it adopts motor direct-drive, impeller shafts directly connects firmly with motor output shaft, and the output shaft of motor is set with rotary sleeve, and rotary sleeve is fixedly connected with also synchronous axial system with cylindric washer; Also be provided with floating type clutch, it has two operating states: namely under dewatering state, and floating type clutch falls and is jointly connected with a joggle with the output shaft of motor and rotary sleeve, to realize output shaft and rotary sleeve synchronous axial system and to drive cylindric washer to rotate.Under washing state, floating type clutch floats and is in the output shaft of motor the state departing from and be connected; Although this washing machine arrangement of clutch opposed configuration is simple, manufacture craft is simple, cost is low, but require higher for water yield during washing of drum type washing machine, if water level is lower, then be difficult to floating type clutch be risen, even if water level is high, due to floating type clutch can be pushed down too when clothes washing stirs.
The application number applied for before applicant is a kind of single container washing and extracting machine of 201320560102.X, comprise outer barrel, interior bucket, impeller and drive unit, described drive unit comprises at least two rotors and at least one stator, wherein a rotor is connected with interior bucket axle, also has a rotor to be connected with impeller shafts; Described drive unit is variable-frequency direct-drive motor, and described rotor, stator, interior bucket axle and impeller shafts are coaxially arranged, interior bucket axle hollow, and impeller shafts is located in interior bucket axle; Impeller and interior bucket rotating in same direction during described washing of drum type washing machine, or rotate backward each other, or one of impeller, interior bucket rotate, impeller and the synchronized in the same way rotation of interior bucket during dehydration.
But, find through many experiments, also there is following defect in it: because direct driving motor driving rotor best effort scope is the rotating speed of 600-800 rev/min, now energy consumption is relatively less, if it is higher with the energy consumption on the contrary that slowly runs to control rotor, need to consume extra energy consumption to control this slow-speed of revolution, more a lot of than using high rotating speed to consume energy consumption height, and the scheme that said structure adopts birotor difference Direct driver impeller and interior bucket to rotate, when washing, the rotating speed of interior bucket and impeller is lower, be generally 100-150 rev/min, if maintain the slow-speed of revolution of two rotors when washing and rinsing simultaneously, then need higher additional energy, due to washing process, clean in the factor of ratio affecting clothing, the rotating speed controlling impeller stirring clothing and current account for very large ratio, if birotor maintains two slow-speed of revolution together, then need more energy consumption.
In addition, because the change of washing process control wave wheel speed is more, rotor speed change acts directly on impeller shafts and impeller, and rotation speed change is stiff, and not buffering, does not cause clothing to be wound around, and affects clean result and larger to the loss of rotor and impeller shafts.
In view of this special proposition the present invention.
