Abstract

The utility model discloses a tri-speed ratio power washing machine, comprising an inner barrel (1), a center wave wheel (3) at the downside, a circumferential wave (2) sheathed outside the center wave wheel (3) and a planetary speed-down clutch (4), wherein the inner barrel (1) has a bottom (11), and the circumferential wave wheel (2) and the center wave wheel (3) are all positioned above the bottom (11) of the inner barrel (1). Compared with the existing technology, the utility model is additionally provided with a washing wave wheel which the rotation rate is inconsistent with both the inner barrel and the center wave wheel and the direction of rotation is converse with either of the inner barrel or the center wave wheel, thus the water current in the inner barrel is driven by a tri- ratio rotary forces of different speeds from the inner barrel, the circumferential wave wheel, and the center wave wheel, creating a fire-new tri-speed ratio power washing machine. The flow intensity is obviously increased, forming a bigger water flow capable of tumbling, directly enhancing the washing and twisting force, and improving the scrubbing effect large amounts. Furthermore, the structure is simple and easy to be executed.

Description

A kind of powered washing machine with three speed ratios

Technical field

The utility model relates to the technical field of rotary drum washing machine, especially refers to a kind of powered washing machine with three speed ratios.

Background technology

Traditional rotary drum washing machine, the impeller that it includes outer bucket, interior bucket and is positioned at the bucket bottom, and suitable by the speed-reducing clutch driving impeller that is positioned under the impeller against the direction rotation, the rotation thereby interior barrel of interior water of drive and clothing are taken advantage of a situation produces clothing and rubs with the realization washing function with interior barrel.But this traditional rotary drum washing machine washing form is more single, and the washing cleanliness is not ideal enough.

And at present, some washing machine manufacturing enterprises designed a kind of when washing in the also revolvable washing machine of bucket.Though this washing machine is when washing, produced certain effect, but when the user when reality is used, put into a large amount of clothings or more thick and heavy clothing after, clothing can sink to the bottom, clothing is followed the impeller rotation, at this moment with the local wash clean of interior bucket friction, but there is not wash clean at the clothing of bottom, be by washing running for a long time, utilize the current rotation, slowly wash clean.

Summary of the invention

Technical problem to be solved in the utility model is the present situation at prior art, provides that a kind of washing-twisting force is stronger, washing cleanliness better powered washing machine with three speed ratios.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this powered washing machine with three speed ratios, include interior bucket, be positioned at the center impeller and the planetary speed reducing clutch of its bottom side, it is characterized in that: the periphery at described center impeller also is arranged with annular impeller.

For the current in the bucket in making can form bigger rolling and the penetrability current when rotated, with further reinforcement washing cleanliness, bucket can have the bottom in described, and described center impeller annular impeller all is positioned on the bottom of this bucket, like this when washing machine is worked, current within the interior bucket are promptly driven by the revolving force from whole interior bucket, annular impeller, three kinds of speed ratios of center impeller, avoided the single drawback of original flow form, flow intensity also obviously increases, form bigger rolling and the current of penetrability, directly improved the washing cleanliness.

And described center impeller can be designed to smooth impeller by actual conditions, or the high impeller of central protuberance, again or the barrel-shaped impeller of central dip.

Wherein, described planetary speed reducing clutch is the speed-reducing clutch with dual output port, and rotate reverse each other, include central shaft and external toothing, wherein, central shaft is the center output shaft, external toothing then drives the outer ring output shaft, the promptly reverse each other running of center output shaft and outer ring output shaft, specifically being combined into of this planetary speed reducing clutch and existing washing machine: the center output shaft of planetary speed reducing clutch drives the center impeller and rotates, and the outer ring output shaft of planetary speed reducing clutch drives interior bucket rotation.

Above-mentioned annular impeller can adopt its rotation of independent motor-driven, but process for ease of actual production, reduce production costs, the central shaft periphery of described planetary speed reducing clutch can be provided with gear, and between this central shaft and external toothing, also be provided with a circle small planetary gear, and this small planetary gear is provided with the central shaft that links to each other with described annular impeller transmission, and promptly the central shaft of this small planetary gear drives described annular impeller rotation.This small planetary gear can be according to the speed ratio and the gear ratio of central shaft and external toothing, and then central shaft or external toothing rotate, thereby form the 3rd output, promptly the direction of rotation with center output shaft or outer ring output shaft is identical, but rotating speed is different the 3rd output fully, and this 3rd output makes above-mentioned powered washing machine with three speed ratios become possibility.

For driving annular impeller more stably, the central shaft that makes small planetary gear rotates, the periphery up and down of described small planetary gear can be provided with planet carrier, the top that is planet carrier is positioned on the top of small planetary gear, and the bottom of planet carrier is positioned under the bottom of small planetary gear, and the central shaft of described small planetary gear is inserted in the top and bottom of described planet carrier, the top of planet carrier then directly links to each other with described annular impeller transmission, and the top of described planet carrier and bottom riveted are together, the central shaft of small planetary gear just drives the planet carrier rotation like this, then drive annular impeller rotation, and stable working.

Compared with prior art, advantage of the present utility model is: by on the basis of original rotary drum washing machine, set up one inconsistent with interior bucket and center impeller rotary speed, and with both one of the reverse each other washing wave wheel of direction of rotation, make washing machine when work, current quilt within the interior bucket is from interior bucket, the annular impeller, the revolving force of three kinds of different speed ratios of center impeller drives, avoided the single drawback of original washing form, created a kind of brand-new powered washing machine with three speed ratios, its flow intensity obviously increases, form bigger rolling and the current of penetrability, and the power running by three speed ratios, directly strengthened washing-twisting force, increased substantially the washing cleanliness, its effect of bringing is conspicuous, and structure is comparatively simple, is highly susceptible to implementing; Simultaneously, the improvement of planetary speed reducing clutch makes the enforcement the technical solution of the utility model become possibility again; The utility model design is ingenious rationally, and running is steady, and service life is longer, and is easy to produce assembling, and cost is lower.
