Abstract

The utility model relates to an impeller for a sprain washing machine; wherein, the structure comprises a tray and a rubbing rib and a leak hole, which are arranged on the tray. A group of impellers are symmetrically arranged above the tray and gradient joint face is arranged at both sides of the impellers to integrate the impellers and the tray together smoothly. Under the driving of the motor, the impellers rotate alternatively in a counter-clockwise direction. Because the main visual direction of the blade is S-shaped and the gradient joint face at both sides are in the shape of cambered surface. When the impeller rotates clockwise, the water velocity at the near outside of the washing cylinder is stronger, while the water velocity at the middle part of the cylinder is weaker; in reverse, when the impeller rotates counterclockwise, the water velocity at the near outside of the washing cylinder is weaker, while the water velocity at the middle part of the cylinder is stronger. So, the washing machine can avoid the defect that the centrifugal water flow outside is much stronger that the water flow in the middle when the impeller of a traditional washing machine is rotating and is favorable for rolling of washings, so that the washings are uneasily kinked up and damaged severely by washing water and the washing power is improve at the same time.

Description

Agitation wheel for washing machine sprains

Technical field

The utility model relates to a kind of washing machine, especially relates to a kind of washing machine impeller structure to existing symmetry and carries out improvement design, is intended to improve the scourability and the washing uniformity etc.

Background technology

Washing machine is very universal, is a good assistant who does housework, and it adopts washings, washing agent etc. more easily to remove in laundry operation and treats dirt and other foreign substance in the washing.According to mode of washing, washing machine can be categorized as current vortex type washing machine, current agitating type washing machine and roller washing machine.Current vortex type washing machine comes washing clothes to treat frictional force between washing, and promptly the impeller of washing machine drum bottom drives with along alternately rotation of counter-clockwise direction by motor, and the entad type current of generation make treats that washing is in contact with one another friction.In traditional washing machine, because being the upper surfaces from substrate, a plurality of stirring vanes radially form, and mostly be linear pattern, so it is stronger than the center in the substrate outside that stirring vane produces the friction current of washings, treat washing to be driven and enter substrate center, thereby treat that washing is easy to by the fierce kink of current and damages.Patent retrieval finds that the someone has applied for agitation wheel for washing machine (97207242.x), and long wave shape convex vein and shortwave shape convex vein are arranged on the dished wheel of this impeller, the spill blade that circumferentially is formed with the band helical angle at its center.Thereby make washing machine when work, around under the effect of long and short waveform convex tendon, the washing clothes in the washtub being pushed to, make current be swirl shape simultaneously, rotate with impeller, cause from bottom to top and roll to promote clothing.Also have a kind of agitation wheel for washing machine (98108797.3), comprise a main body that is installed in the bottom of washing drum, the upper surface that has blade wheel chamber and be formed with at least one water spray outlet; Water spray impeller with impeller shaft and a plurality of flabellums that radially extend from impeller shaft, thus this water spray impeller produces washing current upwards with respect to the main body rotation; Can be at the support unit of swivel bearing impeller shaft radially and axially; And the parts that make the rotation of water spray impeller.These two patents all can strengthen clean result, and can avoid the distortion and the entanglement of clothing, but compare with the utility model, and structural difference is arranged.

Summary of the invention

The utility model mainly is to solve existing symmetrical line to be existing the rolling of impeller and to owe evenly the not high technical problem of the washing uniformity.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: comprise pallet, stranding clothing muscle and leaking hole provided thereon, be symmetrically arranged with blade thereon, the main muscle that it is characterized in that described blade is " S " type, the gradient joint face of being located at its both sides is cambered surface, and itself and pallet fairing are linked into an integrated entity.Owing to adopted said structure of the present utility model design, when impeller turned clockwise, the water velocity in the nearly outside of laundry cylindrical shell was stronger, and cylindrical shell middle region water velocity a little less than; On the contrary, when impeller is rotated counterclockwise, the water velocity in the nearly outside of laundry cylindrical shell a little less than, and cylindrical shell middle region water velocity is stronger.In other words, when agitation wheel for washing machine was made direction of rotation and changed, VELOCITY DISTRIBUTION of its washing current was obviously different, and the degree of passing of water velocity difference increases, and was beneficial to overcome in the prior art washings problem very uniformly of rolling.

Wherein, described main muscle " S " type departs from apart from selecting within the specific limits.A kind of comparatively suitable selection can be: described main muscle " S " type depart from apart from close with the width of main muscle with.Like this, make that the distribution of water flow velocity and degree of passing thereof is preferable, structural design is comparatively reasonable.

Therefore, the utlity model has structure practicality, reasonable, washings rolls evenly, is beneficial to washing clothes, and washability further improves, and design is unique, good looking appearance, and the washing uniformity is than characteristics such as height.In addition, the utility model moulding is simple, produces, processing technology is also very simple, and cost of manufacture reduces greatly.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model.

The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment: the agitation wheel for washing machine that sprains, structure comprise pallet 1 and stranding clothing muscle 2 and the leaking hole 3 be located on the pallet 1, and pallet 1 top is arranged with one group of blade 4, and blade 4 both sides are provided with gradient joint face 5, and blade 4 and pallet 1 fairing are linked into an integrated entity.

Impeller is under the driving of motor, alternately to rotate along counter-clockwise direction, because blade master apparent direction is " S " type, and the gradient joint face of its both sides is arc surfaced, when impeller turned clockwise, the water velocity in the nearly outside of laundry cylindrical shell was stronger, and cylindrical shell middle region water velocity a little less than; On the contrary, when impeller is rotated counterclockwise, the water velocity in the nearly outside of laundry cylindrical shell a little less than, and cylindrical shell middle region water velocity is stronger.Like this, just avoided the entad type current outside that the conventional washer impeller produced when rotated more much better than, be beneficial to rolling of washings, and be difficult for being washed the fierce kink of current and damage, also improved washability simultaneously than the center.

The utlity model has rational in infrastructurely, washings rolls evenly, and washability further improves, and design is unique, good looking appearance, and the washing uniformity is than characteristics such as height.

Claims

1. agitation wheel for washing machine that sprains, comprise pallet, stranding clothing muscle (2) provided thereon and leaking hole (3), be symmetrically arranged with blade (4) thereon, the main muscle that it is characterized in that described blade (4) is " S " type, the gradient joint face (5) of being located at its both sides is cambered surface, and itself and pallet (1) fairing are linked into an integrated entity.
