Washing machine driving system and washing machine

Abstract

The invention discloses a washing machine driving system and a washing machine. The system comprises a rotating body and a transmission device, the transmission device comprises a speed reducing mechanism, a clutch mechanism and a mounting shell, the rotating body is a PSC motor and comprises an outer rotor component and an inner stator component located inside the outer rotor component; the speed reducing mechanism comprises a gear speed reducer, a drive shaft connected with the gear speed reducer and a drive shaft sleeve which is arranged outside the drive shaft in a sleeving mode and rotationally connected with the drive shaft, and the input end of the drive shaft is fixedly connected with the outer rotor component; the mounting shell comprises a stator mounting disc and a mounting plate, and the speed reducing mechanism is located in a cavity formed by the stator mounting disc and the mounting plate which are fixedly connected. Accordingly, the conditions that the structure is simple and compact, and the occupied space is small are met, and meanwhile the motor size is small, the cost is low, few connecting parts exist, the manufacturing technology is simple, and the washing machine driving system is very suitable for large-scale application and popularization and especially suitable for being applied to the field of mid-low-end washing machines used by wide households.

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.
