Background technology
Traditional washing machine is made up of washtub, motor, decelerator and impeller.During washing machine, motor positive direction under the control of control system is rotated, and the rotation of motor is transferred to the wheel for inputting of decelerator by the V-belt, and decelerator utilizes gear drive (for example planet circular system) the high rotating speed of motor to be converted to the slow-speed of revolution of impeller.Impeller is forward and reverse rotation under the driving of decelerator, drives clothing and water and rotates the realization washing.This kind washing methods finds to exist some defectives by practice test: 1, only depend on the impeller rotation to produce current, current are single, and the clothes washing uniformity is not high.2, clothing easily produces when washing and twines.In order to overcome the appeal defective, some washing machine manufacturing enterprises design a kind of " double dynamical " rotary drum washing machine, and with the difference of conventional washer be: the impeller axle of traditional decelerator has only one, and impeller is enclosed within on the impeller axle; The decelerator impeller axle of " double dynamical " rotary drum washing machine has two, these two coaxial being nested together of impeller axle, and two impellers are installed in respectively on these two impeller axles, and these two impellers are concentric.Its mode of washing is: two concentric impellers during washing, and rotation simultaneously, rotation direction is opposite, and all dynamic driving rotating ratio of these two impellers is constant.Because two impeller forward and reverse rotations have simultaneously increased flow intensity, have improved clean ratio, water (flow) direction is constantly changed simultaneously, and it is stronger than conventional washer that clothing is rolled.But the weak point of this technical scheme: flow intensity is bigger when 1, washing, and the clothing wear rate is big, is not suitable for washing the clothing of soft cloth; 2, owing to the forward and reverse rotations simultaneously of two impellers, in case twining appears in clothing, the suffered resistance of motor and decelerator itself heightens.By contrast test, under the same test conditions, double dynamical rotary drum washing machine is than the high 5-10K of electric machine temperature rise of conventional washer, and power consumption increases, and the travelling gear life-span of decelerator also reduces than conventional washer; 3, the more traditional decelerator complexity of the reducer structure of " double dynamical ", the manufacturing cost height.
Summary of the invention
Single in order to solve the washing machine current that prior art exists, clean result is not high, easy problem such as winding, and the utility model provides a kind of double wave wheel washer.
The double wave wheel washer comprises washtub, impeller, decelerator and motor.Impeller 2 and outer impeller 1 in described impeller comprises, outer impeller 1 is petal-shaped and is positioned at impeller 2 peripheries; The upper end of interior impeller axle 4 is connecting interior impeller 2, and its lower end is connecting planet carrier 8; External wave wheel shaft 5 is a hollow shaft, and its upper end is connecting outer impeller 1, and its lower end is connecting internal tooth sun gear 10, and interior impeller axle 4 middle parts are plugged in the external wave wheel shaft 5; Described planet carrier 8 is discoid, and its end is laid with plural planetary gear 9, and plural planetary gear 9 meshes with internal tooth sun gear 10 and external tooth sun gear 12 respectively; Form decelerators with upper planetary gear 9, internal tooth sun gear 10 and external tooth sun gear 12 for two, wheel shaft 13 other ends of external tooth sun gear 12 are connecting motor by tape handler.
Described planet carrier 8 is a cruciformity, and its periphery is provided with circular reinforcing ring.
The utility model is compared with prior art and is had the following advantages:
1, input shaft of speed reducer and two impeller axles constitute differential gear train, and two frees degree are arranged.And the free degree of conventional washer decelerator and double dynamical impeller decelerator has only one, and impeller rotating speed and motor speed are than being constant.It is differential gear train that this programme decelerator has two frees degree, the rotating speed of two impellers is not constant, two impellers can be regulated rotating speed automatically according to the variation of load, when an impeller during by stall, another impeller will faster rotational speed, and motor can not reduced power consumption by stall like this, requirement to the power output of motor simultaneously also can reduce, and reduces motor cost.
2, reduction improves and cleans the uniformity the wear rate of clothing.Pledge clothes and twine when one of them impeller (a impeller) resistance is increased, the rotating speed of a impeller will reduce, minimizing is to the wearing and tearing of clothing, the rotating speed of another impeller (b impeller) can quicken to rotate immediately simultaneously, driving current breaks up clothing, after the load of a impeller reduced, rotating speed improved, and b impeller rotating speed descends again.Owing to reduced the dynamics that rubs between impeller and the clothing, clean the uniformity so utilize the water impact clothing to improve, reduce wear rate.
3, constant during the rotating speed of existing agitation wheel for washing machine, no matter the load resistance size all is with certain rotational speed, clothing is twined.For example: when clothing twined in the clockwise direction, the resistance of impeller increased, but impeller still rotates with identical speed in the clockwise direction, can make the winding aggravation.This programme is with regard to good this problem that solved, and when clockwise rotating the load increasing, the impeller rotating speed can reduce immediately, and another impeller oppositely quickens to rotate, and drives the current backward rotation, removes clothing and twines.
4, owing to there are two impellers can change the combination of multiple impeller profile, form multiple current.
