Washing machine driver

Abstract

The invention discloses a washing machine driver which comprises a motor, a washing shaft, a dehydration shaft sleeve sleeved on the washing shaft and a gear speed reduction mechanism. The washing shaft is coaxially arranged inside a motor rotor of the motor and is fixedly connected with an output gear of the gear speed reduction mechanism; and an input gear shaft of the gear speed reduction mechanism is inserted in a shaft hole of the motor rotor. The input gear shaft of the gear speed reduction mechanism is inserted in the shaft hole of the motor rotor, and thus, the gear speed reduction mechanism and the motor are effectively integrated by the motor rotor serving as a gear holder of the gear speed reduction mechanism, so that the axial size of the washing machine driver is reduced and the washing machine driver has a simple and compact structure and occupies a small space. Moreover, the gear speed reduction mechanism has a large transmission ratio range, and thus, the large reduction ratio output can be implemented.

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...

AI Technical Summary

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
