Description

Prevent the method for suspension double-agitator washing machine impeller lined dress and the impeller of this method

Technical field

The present invention relates to a kind of agitation wheel for washing machine, the particularly a kind of method of suspension double-agitator washing machine impeller lined dress and impeller of this method of preventing.

Background technology

The applicant once proposed a kind of throwing and got rid of the application for a patent for invention that washing machine is got rid of in laundering process and throwing, application number 200510093445.X, the washing machine of this laundering process and this method have concurrently rotary drum washing machine clean the rate height, easy to use, price is low, have the roller washing machine water-saving again, save time, the advantage of low wearing and tearing.

This washing machine wave drum used thereof is disclosed in another application for a patent for invention of application number 200510080318.6, this impeller has a disc substrate, at least be provided with one and be roughly parallel to X-axis and X-axis distance and be the drying fin of d on the disc substrate, described disc substrate is made up of outer ring round table surface, main round table surface, bottom anchor ring and the arc surface that connects between outer ring round table surface, main round table surface, bottom anchor ring and the center installation cylinder; At least be provided with a secondary shifting block in the front on round table surface tapered edges edge, outer ring, the front of this pair shifting block is triangular in shape, and its maximum height is between 5～50 millimeters.The effect of secondary shifting block is when the laundry amount is less when not reaching the wording depth of drying fin, finishes the function of the clothing that overturns.But, in use find, when this impeller height with secondary shifting block is higher, can take place between the outer ring taper round table-board of the secondary shifting block of an impeller and another impeller or beating of clamping between second mate's shifting block that washing clothes, impeller distortion bring caused thing at the bottom of entering barrel from the impeller edge with the bucket friction at the end, foreign matter.

Analyze the lined dress reason and be because:

1, two impellers are to be oppositely arranged with certain angle, when axis whenever rotates a circle separately, distance on two impellers between the corresponding point must be minimum again to the cyclically-varying, particularly wheel rim of maximum and particularly evident near the outer ring round table surface of rim section from being up to.

2, two impellers are in rotary course, the cyclically-varying of the distance between the corresponding point, might not lined dress, the condition that causes lined dress also must be the outline line that possesses lined dress, specifically, may lined dress on two impellers the having of clothes: the bus of a, outer ring round table surface, and just can taking place when only the angle between two buses is less than certain angle, and can be serious more with the lined dress that reduces of angle.In existing suspension double-agitator washing machine, if two impeller end face angles, 50 degree, angle between outer ring round table surface bus and the impeller axis is 75 degree, in rotary course, minimum angle between two buses then is 80 degree, this angle can not constitute obvious lined dress, and result of the test shows that tangible lined dress phenomenon is just arranged when only the minimum angle between two buses is less than 30 °.Because the setting of secondary shifting block, if the minimum angle between the outer ring round table surface bus of the leg-of-mutton outer contour of secondary shifting block and relative impeller is less than 30 °, or in second mate's shifting block arrives simultaneously during with the bottom, the outer contour of second mate's shifting block is less than 30 °, and this will cause lined dress (as shown in Figure 1, 2).In Fig. 1, if secondary shifting block is in the sustained height position, when arriving extreme lower position simultaneously, if second mate's shifting block is excessive height, the also problem that can take place to sting mutually.Among Fig. 2.The secondary shifting block position of two impellers differs 180 °, can not take place to sting mutually, but the minimum angle between the outer ring round table surface bus of the leg-of-mutton outer contour of secondary shifting block and relative impeller approximately has only degree more than 10, therefore the lined dress problem will inevitably take place.

The solution of this problem mainly is shape and the height that improves secondary shifting block.
