Abstract

The utility model relates to an impeller of a washing machine. An inner gear seat which is laid at the bottom of a washing tub can be used as a central impeller according to necessary; the side of the washing tub is provided with an off-center impeller; a power transmission mechanism is used as a group of planetary gear mechanisms. The central impeller and the off-center impeller run on opposite ways, stirring a larger swirl which disappears in a minute. The utility model has the advantages that the damage to the washed fabrics is small; water can hardly overflow; the degree of the dispersion of the fabrics in the washing tub is good; agglomerating rotation is scarcely caused; the wash is uniform; the effect is good. The utility model is an ideal improved device of a domestic impeller type washing machine.

Description

Impeller of washing machine

The utility model relates to a kind of fabric cleaning machine parts, is a kind of improvement to the pulsator apparatus of pulsator washing machine.

Pulsator washing machine is simple in structure, cheap and promoted rapidly with it, this class washing machine or what use at present is single formula impeller, its impeller is arranged on the middle part of washtub, or off-axis installs, and they are all driven by a main shaft and do positive and negative rotation, by several convex tendons arranging radially on the impeller when rotated to the level and vertical two component of water generates, make water form level and vertical vortex, cause the stirring of rolling of being washed fabric, hit mutually and squeeze friction, reach the purpose of cleaning.But this single formula impeller structure, rotation under main shaft drives, above the impeller center, form a maelstrom easily, water and fabric are got rid of to the bucket wall, big to the damage of fabric, water is easily excessive, water consumption is big, and these 2 is again that pulsator washing machine is compared with agitator type washing machine with tumbling-box washing machine and the deadly defect that exists, and the decentralization of fabric in washtub is also not satisfactory in addition, agglomerating rotating process is longer, influences clean result.

The problems referred to above at the prior art existence, the purpose of this utility model provides a kind of compound impeller, carry out planetary rotation, can above the impeller center, not form a maelstrom, be washed fabric and can not get rid of and beat at the bucket wall, little to fabric damage, water is difficult for excessive, water consumption is less, and fabric is the decentralization height in washtub, and the planet that produces agglomerating rotation hardly rotates compound pulsator apparatus.To preserve the advantage that rotary drum washing machine is simple in structure, cost is low, easy to maintenance, overcome and decrease the shortcoming that clothing is serious, use water rate.

The purpose of this utility model can realize by following measure: it is by impeller, compositions such as axle and power drive mechanism, the internal tooth wheel seat is layered on whole washtub bottom, main shaft is at this center, it is the garden ring gear at center that the lower surface of internal tooth wheel seat is fixed with the main shaft, main shaft is fixed with the internal tooth wheel seat from top to bottom successively, master gear, the planet master gear, pass axle bed again, eccentric impeller axle is at the other internal tooth wheel seat that passes of main shaft side, the top is fixed with eccentric gear, the lower end is fixed with eccentric impeller gear, master gear engagement on this gear and the main shaft, between planet master gear and the internal gear carrier gear is arranged, the three is intermeshed, and bridge gear shaft is fixed on the axle bed.

Above-mentioned purpose can also give perfect by following measure: produce bigger vortex for making washings, the friction kneading action of fabric when washing washed in increase, should be with the internal tooth wheel seat both as pinion stand, again as the center impeller, so can there be the convex tendon the same with eccentric impeller on the surface thereon.

Also just because of be the vortex power of considering to increase current, in planetary gear drive, the carrier gear of considering is a pair of, and they are installed between planet master gear and the internal gear side by side, and internal tooth wheel seat (being the center impeller) and eccentric impeller are run in the opposite direction.If have only a carrier gear, and then center impeller and the equidirectional motion of eccentric impeller, vortex power is little, and current reduce the laser printer power of fabric.

Drawing of the present utility model is described as follows:

Fig. 1 is the structural representation of this device.

Fig. 2 is the upward view of Fig. 1.

The utility model is described in detail below in conjunction with embodiment: this pulsator apparatus can be to existing, every impeller is installed in the simple type at washtub middle part, twin-tub semi-automatic and full-automatic type are reequiped, the internal tooth wheel seat (being the center impeller) 4 that system is moulded in requirement has certain intensity and thickness, upper surface has convex tendon, lower surface is fixed with internal gear 7, main shaft 2 tops fixed by nut internal tooth wheel seat 4, middle master gear 5, planet master gear 8, carrier gear 9 and eccentric ripple gear 6 are separately fixed at main shaft 2, on bridge gear shaft 10 and the eccentric impeller axle 1, their available pin keies are combined closely, main shaft 2 passes an end of the microscler axle bed of class 11, also is welded with two bridge gear shafts 10 on the axle bed 11.To capacity is that 2Kg(refers to the dry fabric amount) washing machine wash, the diameter of eccentric impeller 3 is about 185mm, rotating speed is about 500 rev/mins, total principle is that large diameter impeller should be the slow-speed of revolution, the high rotating speed of minor diameter, so that their linear velocity is in the 4-7m/ scope of second, according to this point, the number of teeth meter of gear drive of the present utility model is established and is: the number of teeth of internal gear 7 is 75-90, carrier gear 9 is 16-20, master gear 5 is 30-35, and eccentric impeller gear 6 is 16-20, and planet master gear 8 is the 8-16 tooth.

If be specifically designed to thin fabric, to wash a little less than carrying out as silk, georgette and so on, the upper surface of internal tooth wheel seat 4 can not have convex tendon, makes it not play the center impeller.

As planetary transmission mechanism, though also can adopt 45 ° of helical gears, because of the planetary transmission mechanism of helical teeth crop rotation, its shared space is big more than face gear, so inadvisable.

Main shaft 2 rotates, make the same together direction rotation of fastening master gear 5, planet master gear 8 on it, 6 reverse rotations of eccentric impeller with master gear 5 engagements, make eccentric impeller 3 also do reverse rotation, planet master gear 8 is under the transmission of a pair of carrier gear of installing side by side 9, making internal gear 7 drive internal tooth wheel seat 4(is the center impeller) do and main shaft 2 unidirectional rotations, so just make center impeller and eccentric impeller 3 in washtub, make planet and rotate, produce desirable vortex.

This pulsator apparatus has being washed fabric damage little compared to existing technology, and water is difficult for excessive, and fabric is the decentralization height in washing tube, can produce agglomerating rotation hardly, washs the advantages such as even. The advantages such as it is simple in structure that rotary drum washing machine has been preserved, with low cost, easy to maintenance have been abandoned and have been washed the shortcoming that fabric damage is big, use water rate, make in the washing machine of different model, have strengthened competitiveness.
