Description
Technical field
The present invention relates to washing machine field, especially a kind of power transmission structure of rotary drum washing machine.
Background technology
The dynamic transfer system structure of existing impeller automatic washing machine generally drives speed change clutch by motor by belt pulley, and then realize washing and dehydration by speed change clutch, this washing machine dynamic transfer system structure assembling is comparatively complicated, therefore while assembling, the time of cost is longer, thereby production efficiency is lower, and manufacturing cost height also easily breaks down.And the cost of speed change clutch is higher makes whole power transmission structure cost in about 100-130 unit, cause the cost of washing machine also to increase thereupon.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology and provide a kind of simple in structure, the power transmission structure of the rotary drum washing machine of low cost of manufacture.
In order to achieve the above object, the power transmission structure of the designed a kind of rotary drum washing machine of the present invention, it comprises motor, impeller, dehydration barrel, steel ladle, decelerator and suspension rod damper, described impeller, dehydration barrel and steel ladle arrange successively from inside to outside, suspension rod damper is connected on steel ladle, motor is fixed on the bottom of steel ladle, decelerator is arranged in dehydration barrel, described decelerator comprises decelerator cover, planetary gearsets, reducer input shaft and reducer output shaft, planetary gearsets is arranged in decelerator cover, reducer input shaft is connected with motor output shaft by connecting bushing, reducer output shaft is connected with impeller, and be provided with flange shaft sleeve on the power shaft of decelerator, the top of flange shaft sleeve is fixedly connected with dehydration barrel, the bottom of flange shaft sleeve is fixedly connected with brake wheel, be provided with brake ribbon in brake wheel outside, the center of the bottom of steel ladle is provided with the first water seal and bearing, the first water seal and bearing are combined by positioning framework, one end of positioning framework is provided with flange, be fixed on the bottom of steel ladle by flange, be provided with the first groove on the top of decelerator cover, be provided with the second water seal and oiliness bearing in the first groove, reducer output shaft is through the second water seal and oiliness bearing.This structural electromotor is through motor output shaft outputting power, and is directly connected with connecting bushing, and then is connected with the power shaft of decelerator, drives impeller to rotate produce clean result after decelerator slows down by reducer output shaft outputting power; Directly by several independent parts, decelerator is arranged in dehydration barrel simultaneously, has simplified the structure of product.Because flange shaft sleeve lower end is connected with brake wheel, dehydration barrel is fixedly connected with flange shaft sleeve again, therefore brake ribbon was embraced brake wheel and equaled to have embraced dehydration barrel when washing, so decelerator slows down when washing, reducer output shaft low speed rotation realizes washing, and dehydration barrel does not turn; And when dehydration brake ribbon loosen brake wheel, realize centrifugal dehydration.Control like this brake ribbon and embrace brake wheel and just equal to have embraced dehydration barrel dehydration barrel is stopped operating, brake ribbon loosens brake wheel just to be equaled to have loosened dehydration barrel and makes dehydration barrel can recover again to rotate.
In order to realize conversion, one between washing and two kinds of patterns of dehydration: described connecting bushing is provided with ratchet, ratchet, clutch spring cover and embraces spring composition clutch structure, embrace the upper end of spring and hold tightly and be connected with brake wheel.Described ratchet and clutch spring cover are made into integration, and brake wheel, flange shaft sleeve and dehydration barrel are connected as a single entity.When washing, ratchet is stirred ratchet, makes to embrace spring and loosens connecting bushing, realizes washing function at a slow speed; And when dehydration ratchet loosen ratchet, therefore embrace spring and embrace connecting bushing, now realize high speed centrifugation rotation, the more simple and reliable and fault rate of this project organization also greatly reduces.
The another kind of scheme that realizes realization conversion between washing and two kinds of patterns of dehydration is: described impeller has floating plate structure, described floating plate structure comprises floating plate, boss and guide pillar, boss is arranged on the lower plane of floating plate, guide pillar and impeller simultaneously injection molding form, be provided with several the second grooves at dehydration bucket bottom, and the position of the second groove is corresponding with boss.When washing, floating plate floats by guide pillar in water, and now boss separates with the second groove, and impeller is realized washing with reducer output shaft low speed rotation, and dehydration barrel does not turn; When dehydration, the water in steel ladle is emitted, and floating plate is bottomed by guide pillar free subsidence, and boss drops in the second groove, and impeller drives floating plate, and floating plate drives dehydration barrel, and impeller, floating plate and the dehydration barrel Trinity are rotated, and realize high speed dewatering.
The power transmission structure of a kind of rotary drum washing machine that the present invention obtains, by redesigning the position of decelerator, abandon power transmission structure and the assembly of distinctive belt pulley drive speed change clutch in the past, adopted common electric machine to realize electric-machine directly-driven, energy-saving and cost-reducing fairly obvious; And reduce the space that power transmission structure occupies, reduced the cost that rotary drum washing machine is manufactured, simple and reliable for structure.Brake wheel, flange shaft sleeve and dehydration barrel are connected as a single entity and just can are braked and be brought control dehydration barrel by control like this, more simple and fast of internal control when rotary drum washing machine moves like this, and reduce the fault rate of rotary drum washing machine, even fault maintenance also comparatively easily quick, be suitable for promoting on a large scale and using.The cost of this power transmission structure is greatly about about 30-35 unit, than cost in the past 70%.Design the two cover washings, the dehydration mode conversion plan that coordinate with it simultaneously, for rotary drum washing machine assembling provides a great convenience, greatly improved production efficiency.
