Description
Technical field
The present invention relates to washing machine field, the specifically drive installation structure of washing machine, especially a kind of decelerator for washing machine and electric motor mounting structure and there is the washing machine of this mounting structure.
Background technology
The structure of conventional full-automatic drums sleeved washer is: cover bucket is made up of coaxial inside and outside two buckets.Outer barrel is fixed, and is used for splendid attire cleaning solution, is called steel ladle.On interior bucket sidewall, have many apertures, be used for holding clothing, the difference requiring according to washing, can fix also and can rotate, in the time of washing or rinsing, maintain static, coordinate impeller to complete washing or rinsing function, in the time of dehydration, rotate with impeller, just become the centrifugal dewatering barrel that dries clothing, be commonly referred to as washtub or dehydration barrel.Impeller is the critical piece in washing system, it is arranged on the bottom of washtub, the upper surface of impeller has several convex tendons, under the driving of Power Drive Unit, do forward and reverse rotation with low speed, form eddy current, heart-shaped current, drive clothing and cleaning solution in washtub to roll up and down, under the rubbing actions such as chemical action, souring and the clothing of cleaning solution and bucket wall, impeller, clothing is cleaned.Laundry processes mainly comprises washing, rinsing, three processes of dehydration, and the mutual conversion between three processes of this of automatic washing machine is that Automatic continuous completes.Washing or when rinsing, only has the forward and reverse rotation of impeller low speed and dehydration barrel is motionless; When dehydration, dehydration barrel and the running of impeller synchronous high-speed.
Above laundry processes is all to complete under the driving of washing machine Power Drive Unit, and asynchronous machine, the clutch that the Power Drive Unit of Wave wheel type full automatic drums sleeved washer is mainly 1320rpm by rated speed and three of the belt transmission part that connects the two are formed.Due to washing, the rotating speed of impeller is slower when rinsing, and the rotating speed of dehydration barrel is very fast when dehydration, so clutch generally all adopts mechanical type planetary gear speed-reducing clutch, is called for short speed-reducing clutch.Motor and speed-reducing clutch are that split axle is arranged on steel ladle bottom side by side, and the small belt pulley below motor, the big belt pulley below clutch, by first order belt deceleration transmission, pass to big belt pulley the power of motor, and obtain the rotating speed of about 750rpm.When washing machine is in washing or when rinsing state, then after speed-reducing clutch slows down, make impeller obtain the slow-speed of revolution of about 175rpm, now washing (dehydration) is barrel motionless.When washing machine is during in dewatering state, speed-reducing clutch output, without the rotating speed of the 750rpm slowing down, drives dehydration barrel and the rotation of impeller synchronous high-speed.
Speed-reducing clutch is the critical component in Power Drive Unit, and the wash shaft of speed-reducing clutch is divided into two sections, above one section for washing driven axle, below one section for washing driving shaft.The lower end of washing driving shaft is fixed wtih clutch cover and big belt pulley, and upper end is gear, inserts in planetary reducer and makes constant gear.Washing driven axle lower end is fixed by spline and gear frame, and impeller is installed in upper end.The dehydrating shaft of speed-reducing clutch is also divided into upper and lower two parts, and the first half is concentric locking collar axle construction with washing driven axle.This part of intermediate housing torsion spring, and inside, lower end is installed with planetary reducer, and the outside double brake hubs of doing.The latter half of dehydrating shaft is shorter, and upper end is fixed by bolt and the first half, and lower end contacts with clutch cover.Washing driving axle housing is contained in its centre.Embrace spring and be enclosed within the position that dehydrating shaft contacts with clutch cover.Planetary reduction gear forms by washing driving shaft upper end (sun gear), gear frame, planetary gear and internal gear etc.Internal gear is fixedly connected with dehydrating shaft.
Washing machine is in the time of washing or rinsing state, and drain solenoid valve power-off is closed.Because its armature discharges, shift fork is resetted, an angle dialled by ratchet by the ratchet that is fixed on shift fork lower end, embraces spring lower end and dialled pine because being embedded in the aperture of ratchet inwall.So just, make dehydrating shaft bottom can not engage with clutch cover (washing driving shaft).Because dehydrating shaft is now braked by torsion spring and brake ribbon, be that internal gear maintains static, so in the time that washing driving shaft (sun gear) clockwise rotates, planetary gear is done counterclockwise rotation on one side, revolve round the sun clockwise around sun gear, thereby drive gear frame and washing driven axle to turn clockwise simultaneously.But driving shaft rotates approximately 4.3 weeks, and driven axle just rotates one week.In like manner, in the time of the counterclockwise high speed rotating of washing driving shaft, driven axle also slowly runs counterclockwise.
Washing machine is in the time of dewatering state, and drain solenoid valve energising is opened.Armature, in driving valve opening, also makes brake ribbon loosen brake disc, and makes shift fork drive ratchet to loosen ratchet.In the time that clutch cover (washing driving shaft) is made clockwise high speed rotating, just in time make to embrace spring and screw, thereby dehydrating shaft is engaged with clutch cover.At this moment because internal gear is also with dehydrating shaft high speed rotating, so planetary gear is identical around the rotating speed of sun gear revolution with the rotating speed of sun gear, internal gear.Wash driving shaft, dehydrating shaft (dehydration barrel) and washing driven axle (impeller) and do synchronous high-speed running, and because this clockwise rotating is just in time that torsion spring is dialled loose direction, so torsion spring is to dehydrating shaft Braking Action None.
Can find out by analysis above, mainly there is the problem of following several respects in the Power Drive Unit of conventional full-automatic drums sleeved washer:
1. adopt asynchronous machine, be difficult for forward and reverse Fraquent start, starting torque is little, wash time is long, and starting current has electromagnetic interference to electrical network greatly, asynchronous machine inconvenience low cost, effective speed regulating control in addition, the washing speed that cannot realize wide region adapts to the requirement of different clothings to washing speed, and dewatering speed is low, centrifugal force is little, and clothes dewatering is insufficient;
2. motor and speed-reducing clutch can only do unidirectional High Rotation Speed in dehydration, and there is to impact in the life-span of whole drive unit;
3. motor output shaft and wash shaft, dehydrating shaft are that split axle is set up side by side, dehydration barrel imbalance, though by addition balance of balance weight, be also difficult to reach balanced, impeller easily produces and vibrates and noise during with dehydration barrel rotation;
4. first order belt deceleration transmission efficiency is low, fault rate is high, the life-span is limited, and has noise when transmission, and when washing, belt easily skids, and the forward and reverse angle turning over of impeller is unequal, and clothing is easily wound around, and dewatering speed is low, and clothes dewatering is insufficient;
Speed-reducing clutch complex structure, fault rate is high, production cost is high, installation and maintenance inconvenience, increase customer using cost, efficiency is low, mechanical noise is large;
6. in dehydration time,, clothing is put inhomogeneous while causing imbalance in dehydration barrel, because motor can only carry out unidirectional rotation, carries out the self balancing time long, sometimes also cannot balance;
7. adopt double reduction transmission, whole unit efficiency is low, energy loss is larger.
