Washing machines and washing machine drives

Abstract

The invention relates to a washing machine and a transmission device for the same. The washing machine comprises a box body, an external barrel, an internal barrel, a wave wheel, a control system, an electric motor, a transmission shaft, a bearing seat and a bearing, wherein the upper end of the shaft of the electric motor is directly embedded into the lower end of the transmission shaft in an inserted connection mode so as to realize transmission; an external spline is fixed on the transmission shaft; an internal spline matched with the external spline is fixed at the bottom of the internal barrel; and during washing or dewatering, the internal spline and the external spline are separated and meshed respectively so as to realize washing and dewatering functions. By improving the washing machine and the transmission device, the washing machine and the transmission device have simple and compact structural designs, save cost, are convenient to produce, disassemble and assemble, and meet the personalized requirements of users.

Description

Technical field [0001] The invention relates to a washing machine and a transmission device of the washing machine, in particular to a washing machine and a transmission device in which a motor shaft is directly connected with a transmission shaft that drives a pulsator to rotate, and the washing and dehydration functions are realized through spline engagement and separation. Background technique [0002] The existing ordinary fully automatic washing machines include washing, rinsing, and dehydration procedures. The transmission system includes motor, cooling pulley, V-belt, pulley, deceleration clutch, etc. During washing, the motor power is transmitted to the pulsator through the two-stage deceleration of the belt and the reducer, and the pulsator is driven to rotate forward and backward, and the inner tub does not rotate to wash the clothes; when dehydrating, due to the action of the clutch, the pulsator and The inner bucket rotates at high speed in the same direction, and th...
