Description
Technical field
The present invention relates to roller washing machine technical field, more particularly to roller washing machine speed-reducing clutch.
Background technology
Existing roller washing machine washing principle：
The built-in horizontal rotatable cleaning-drum of roller washing machine, has leaking hole and is furnished with the convex body rib of axial direction etc. point arrangement, when cylinder is with appropriate speed on cylinder wall（50-60rpm）During rotation, clothing in cylinder produces tumbling motion in the cleaning solution under gravity, centrifugal force and the action of rib support use in cylinder, cause the friction souring between clothing and between cleaning solution, there is part of article to be thus lifted to close cylinder top again, depart from barrel under gravity, generation is fallen, impacts, washing away and friction cleaning function, while the mode of the effect and the positive and negative rotation that alternates by drop realizes that clothing position is periodically exchanged, reaches the purpose of uniform washing.
Relative to pulsator washing machine, roller washing machine washing is softer, and its advantage is little wear of clothes, water-saving, washs uniform, and shortcoming is also corresponding：It is little due to washing scouring force, it is necessary to wash the longer time；For preferably decontamination, the clean ratio of standard requirement is reached, it is necessary to heat, conclusion is exactly that roller washing machine more takes electricity.
Without speed-reducing clutch on existing roller washing machine, the deceleration inner cylinder rotating that motor passes through belt pulley, the dehydrating speed of roller washing machine is about 800-1200rpm, washing rotating speed only has 50 ~ 60rpm or so, therefore very big speed reducing ratio is needed in washing, double-speed motor is usually used, or by direct driving motor speed governing, which kind of mode can all increase cost and power consumption, not only motor is expensive, and energy consumption is big, mode of washing is single, clean result is undesirable, seek a kind of comprehensive drum clutch of mode of washing and its washing machine is our technical issues that need to address.
The content of the invention
The first object of the present invention is to provide a kind of roller washing machine speed-reducing clutch, with reduces cost, overcomes drawbacks described above.
It is another object of the invention to provide a kind of roller washing machine, to save electric energy, overcomes the drawbacks described above of existing roller washing machine.
The third object of the present invention is to provide a kind of washing methods of roller washing machine, to enrich the mode of washing of existing roller washing machine.
The purpose of the present invention can be achieved in the following manner：
In order to realize the first purpose, described roller washing machine speed-reducing clutch, including the Upper shaft sleeve being connected with inner tank of washing machine, drive shaft is actively provided with by upper bushing in described Upper shaft sleeve, described drive shaft is provided with sun gear, described drive shaft is outer to be flexibly connected with one heart by lower bushing with Lower shaft sleeve, it is connected with planet carrier on described Lower shaft sleeve, it is flexibly connected with closure by middle bushing outside described Lower shaft sleeve, described closure is connected by internal-gear shell with described Upper shaft sleeve, described internal-gear shell is connected with internal gear, described planet carrier has been moveably mounted planetary gear by planet axis, it is meshed with sun gear in described planetary gear, it is meshed with internal gear outward.
Described internal gear is integrated by being arranged at the concave tooth arranged on the double wedge of its outer wall and internal-gear shell inwall and being fastenedly connected.
The number of teeth of described internal gear is 2～4 with the gear ratio of sun gear:1.
Described closure is fastenedly connected by roll riveting with internal-gear shell and is integrated, and described internal-gear shell is fastenedly connected by interference press-fitting with described Upper shaft sleeve and is integrated.
Retainer ring and little oil sealing are additionally provided between described Upper shaft sleeve and drive shaft, described sun gear is made up of metal material, and described planetary gear and internal gear is made up of plastic material.
Upper bushing between described Upper shaft sleeve and drive shaft is 1 or more than 1.
Lower bushing between described drive shaft and Lower shaft sleeve is 1 or more than 1.
The output end of described drive shaft is connected with agitator, and described agitator is concentrically attached in the inner tank of washing machine being connected with Upper shaft sleeve, and the input of described drive shaft is connected with motor, and described drive shaft is connected by clutch with Lower shaft sleeve.
Motor is connected with described drive shaft and is rotated in the presence of motor；
During washing operating mode, the power of described drive shaft directly drives agitator to rotate, meanwhile, after planetary gear speed-reduction, Lower shaft sleeve is motionless under the control of clutch, and Jing internal gears, internal-gear shell, Upper shaft sleeve drive inner core and agitator counter rotating；
During dehydration condition, the clutch installed on the driving shaft connects as one drive shaft with Lower shaft sleeve, engage with rotor, the internal-gear shell that planet carrier is connected with Upper shaft sleeve is driven to drive the common synchronous rotary of internal gear by Lower shaft sleeve, thus the inner core being connected as a single entity with Upper shaft sleeve obtains the agitator 1 being connected as a single entity with drive shaft:1 gearratio synchronous high-speed rotation, high speed centrifugation dehydration.
Compared with prior art, the advantages of the present invention are：
1st, technical solution of the present invention is adopted, because speed-reducing clutch is per se with deceleration, motor speed is too low without adjusting during washing, the motor that can thus make dual output roller washing machine remains the state that efficient high-speed operates, and improves electric efficiency；
2nd, using the speed-reducing clutch of technical solution of the present invention, agitator is directly driven by drive shaft during washing, and inner core is driven by Upper shaft sleeve and internal-gear shell, planetary gear stress is little, plastic material can be adopted, noise is advantageously reduced on the premise of proof strength, overcome existing dual output clutch（With reference to poly- grand relevant patent）Interior bucket driving is engaged with internal gear by fixed shaft gear, fixing axle strength of gear is larger；Connected using bearing between its Upper shaft sleeve and braked wheel, less stable during high speed dewatering, be also easy to produce the defect of vibration and noise；Simultaneously because combined using interference press-fitting and roll riveting mode between Upper shaft sleeve, internal-gear shell, closure, rolling bearing be separately mounted to Upper shaft sleeve and closure it is cylindrical on, rigidly good during dehydration, stability is strong, and vibration noise is low.
3rd, using the washing machine of technical solution of the present invention, an agitator is increased in the inner core of conventional drum washing machine（Impeller）, agitator and inner cylinder rotating it is in opposite direction, form double dynamical washing, make clothing that stirring and tumbling action are increased during throwing-beating-throw again, improve and clean ratio, it is not necessary to heat, so as to economize on electricity.
