Description
Technical field
The present invention relates to field of home appliance technology, the drive systems in particular to a kind of roller washing machine and one
Kind includes the roller washing machine of the drive system of the roller washing machine.
Background technique
Currently, the washing principle of roller washing machine is that motor is back and forth transported directly or by belt driving washing machine drum circumference
Turn, the lifting rib of inner wall of rotary drum, which lifts clothing, to be shaken loose, and beats washing vacantly to achieve the purpose that clean clothing.This washing side
Formula overcomes the defect of rotary drum washing machine clothing winding and wear of clothes, but wash time is long, and detersive efficiency is lower, cleans and compares
It is low.
In order to improve cleaning capacity, there are some products to use at present and impeller is set in cylinder bottom, makes roller in washing
Opposite operating at different rates, increases the frictional force between clothing, to improve clean ratio between impeller.Such as the Shen of Haier
Number a kind of double-power cylinder washer please be disclosed for 201480002635.3 patent, this washing machine uses outer rotor DD
Motor driven, rotor is directly fixedly connected with impeller by input shaft, synchronized to operate；The sun gear being connected on input shaft passes through
Power at constant speed ratio is transmitted on drum shaft by two-stage planetary gear, realizes impeller and roller differential operating in the same direction.This structure is
It compression axial dimension and realizes installation function, needs to design front and back bearings bracket fissions, gear-box is arranged in front and back bearings
Between, then by assembling connected together front and back bearings bracket.As application No. is the patents of CN201710326312.5 for Haier
In be previously mentioned, this connection type, which will appear, to be loosened at braked wheel and oil sealing cap riveting, causes roller shaking volume greatly to produce
The problems such as raw vibrating noise, needs to add end face bearing or uses other solutions, increases cost and reduces axial dimension benefit
With rate.In addition, conventional drum washing machine rotor is fixed on drum shaft, rigidity is preferable；And existing double-power cylinder washer
Generally rotor is fixed on input shaft, input shaft is elongated shaft, will cause the problems such as rigidity is insufficient.Furthermore this design side
Case revolutionizes the assembly method and connection relationship of conventional drum washing machine drive system, very big to overall design change, and
And have part more, the problems such as assembly difficulty, axial space utilization rate is not high.
Two-power washing machine is relatively suitble to the clear of the wear-resistant clothings such as jeans due to increasing the frictional force between clothing
It is clean, but will cause the accelerated wear test of the clothings such as silk or wool.How to be cut on a washing machine according to the type of washing clothing
It changes single-power and double acting force mode is also roller washing machine problem to be solved.
In addition, existing jaw clutch, in general inoperative, which (are not powered on) clutch station under state, is located at washing
State, i.e., the first washing tooth and the second washing tooth are in meshing state, and when system issues elution conversion instruction, clutch exists
Switch clutch sliding sleeve operating position under the action of driving source, washing tooth is disengaged from, and dehydration tooth enters engagement, entire transmission system
It runs at high speed under motor drive.This clutch does not need driving force when comparing washing, has the advantages that power saving, but if
Improper power-off occurs when laundry machine dehydration state suddenly, clutch can reset rapidly under power failure state, i.e. dehydration tooth is de-
From engagement, washs tooth and enter engagement.And the washing tooth on rotary part runs at high speed at this time, with the washing tooth in fixation member into
Enter engagement, will cause noise or even beats the destructive results such as tooth.
