A washing machine driving system and the washing machine

Abstract

The invention discloses a washing machine driving system and a washing machine, which include a rotating body and a transmission device, the transmission device includes a reduction mechanism, a clutch mechanism and a mounting housing, the rotating body is a PSC motor, and includes an outer rotor assembly and an inner stator located inside the outer rotor assembly. The subassembly; the reduction mechanism includes a gear reduction system, a drive shaft connected to the gear reduction system, a drive shaft sleeve sleeved on the outside of the drive shaft and connected to it in rotation, and the input end of the drive shaft is fixedly connected to the outer rotor assembly; the installation shell includes The stator mounting plate and the mounting plate, and the deceleration mechanism are located in the cavity formed by the fixed connection between the stator mounting plate and the mounting plate; the present invention satisfies the conditions of simple and compact structure and small space occupation, and at the same time, the size of the motor is small, the cost is low, and the connecting parts less, the manufacturing process is simple, and it is very suitable for large-scale promotion and application, especially suitable for the medium and low-end washing machine field used by a large number of families.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a washing machine driving system. The invention also relates to a washing machine to which the driving system is applied, and is especially suitable for being applied to the field of medium and low-grade washing machines used by families. Background technique [0002] The main work of the washing machine is to drive the pulsator to rotate by the driving mechanism, agitate the water flow and rotate the clothes, so as to achieve the purpose of washing clothes. At present, the power source of the commonly used driving mechanism is a motor, and the torque when the motor rotates is transmitted to the reduction device by the output shaft of the motor, and then the output shaft of the reduction device is connected with the pulsator, thereby driving the pulsator to rotate. [0003] Ordinary motors have a relatively high speed. In order to obtain a suitable output speed, the motor needs to...

AI Technical Summary

Problems solved by technology

However, because this technology uses a permanent magnet outer rotor brushless DC motor, the cost of the motor is high, and the connection structure between the clutch and the rotor is cumbersome. There are many parts, complex connection, high cost, and not compact enough structure. It is also not suitable for low-end washing machines used by families.
