Problems solved by technology
However, the single-stage planetary deceleration clutch mechanism cannot achieve a large speed ratio deceleration output, and the washing efficiency will be reduced. The requirements on the motor will be high and the cost will increase; if a multi-stage planetary deceleration output is used, it will not only increase the cost but also make the mechanism change. It is complex, not compact, and unstable; the cost of the pulley-type reduction drive clutch mechanism is high, and the belt transmission ratio is inaccurate, the life of the belt is low, and the washing efficiency will also be reduced
In addition, the driver composed of the above-mentioned motor and deceleration clutch device has a relatively large axial size and an uncompact structure.
[0004] There is also a deceleration clutch in the prior art, which changes the original ordinary motor from indirect drive to direct drive, but this kind of drive motor is mostly a DC brushless motor, and a control unit is required for functions such as controller rotation, and the cost of the control unit Higher, and the axial dimension of this kind of drive is larger, not suitable for long-term development

Disclosed is a washing machine driver, comprising an electric motor, a washing axle (51), a dehydration axle sleeve (52) sheathed on the washing axle (51) and a gear reduction mechanism, wherein the washing axle (51) is coaxially mounted inside a motor rotor (23) of the electric motor and is fixed to an output gear (332) of the gear reduction mechanism, and an input gear shaft (31) of the gear reduction mechanism is inserted inside a shaft hole of the motor rotor (23). Since the input gear shaft (31) of the gear reduction mechanism is inserted inside the shaft hole of the motor rotor (23), the motor rotor acts as the gear carrier of the gear reduction mechanism, effectively combining the gear reduction mechanism and the electric motor in one, thereby reducing the axial size of the washing machine driver, making the structure of the washing machine driver simple and compact so as to occupy a small space. Furthermore, since the transmission ratio of the gear reduction mechanism has a large range, a large reduction ratio output can be achieved.
Description
technical field [0001] The invention relates to the technical field of drivers, in particular to a washing machine driver. Background technique [0002] The washing machine is a household appliance commonly used in daily life, and its main working conditions can be divided into washing conditions and dehydration conditions. [0003] The conventional driving unit of the existing washing machine is mainly composed of a motor and a deceleration clutch device. The common motor rotates at a relatively high speed. The currently commonly used deceleration clutch devices mainly include a single-stage planetary deceleration transmission clutch mechanism, a pulley type deceleration motion clutch mechanism or a motor direct drive transmission clutch mechanism. However, the single-stage planetary deceleration clutch mechanism cannot achieve a large speed ratio deceleration output, and the washing efficiency will be reduced. The requirements on the motor will be high and the cost will i...
