Among the figure, 1, the impeller body; 2, impeller washing muscle; 3, small wave wheel center; 4, small echo hub; 5, small wave wheel rotating shaft; 6, cavity; 7, back-moving spring; 8, hook; 9, gland; 10, small echo wheel cap; 11, small wave wheel center spacing preiection; 12, small wave wheel spacer; 13, small wave wheel washing muscle; 14, impeller leaking hole; 15, the little washing muscle of impeller.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
Shown in Fig. 1～7, the utility model comprises impeller body 1 and several impellers washing muscle 2 that are located on the impeller body 1, center and the impeller body 1 coaxial small wave wheel that is provided with above impeller body 1, described small wave wheel comprises the small wave wheel center 3 that is connected with impeller body 1, be sleeved on the small wave wheel center 3 with the small wave wheel rotating shaft 5 of small echo hub 4 one, be provided with a cavity 6 on small wave wheel center 3 tops, cavity 6 is relative with aperture position in the small wave wheel rotating shaft 5, be set with back-moving spring 7 in small wave wheel rotating shaft 5 outsides, the hook 8 at back-moving spring 7 two ends stretches in the cavity 6 grab on the two sides of cavity 6, the gland 9 that is located at back-moving spring 7 tops is connected with small wave wheel center 3, can prevent that back-moving spring 7 and small echo hub 4 from deviating from, be provided with small echo wheel cap 10 at small echo hub 4 tops, make the small wave wheel top more attractive in appearance, more level and smooth.
Be provided with small wave wheel center spacing preiection 11 on small wave wheel center 3, small wave wheel center spacing preiection 11 is relative with small wave wheel spacer 12 positions that are located at small echo hub 4 inboards.
On the lateral wall of small echo hub 4, along the circumferential direction evenly be provided with several small wave wheel washing muscle 13.
On impeller washing muscle 2, be provided with impeller leaking hole 14 and the little washing muscle 15 of impeller.
During work, the utility model is made up impeller be contained in interior bucket bottom, link to each other with the wash shaft of clutch.The wash shaft of clutch drives impeller body 1 and rotates, the wherein hook 8 that the small wave wheel center 3 that is connected with impeller body 1 drives back-moving springs 7 rotates, when impeller body 1 turns to certain position, under the effect of back-moving spring 7 elastic force, another hook 8 of back-moving spring 7 drives small wave wheel by small wave wheel rotating shaft 5 and rotates, the beginning washing clothes.Small wave wheel center spacing preiection of establishing on small wave wheel center 3 11 and the small wave wheel spacer 12 that is located at small echo hub 4 inboards can guarantee impeller body 1 after turning an angle, and successfully small wave wheel are driven to start.
When power stopped, impeller body 1 stopped operating, and under the effect of back-moving spring 7 elastic force, the hook 8 of back-moving spring 7 drives the small wave wheel backward rotation by small wave wheel rotating shaft 5 and resets, and stopped when treating cavity 6 contacts side surfaces of this hook 8 and small wave wheel center 3.
Because small wave wheel starts, rotates synchronously with respect to the hysteresis of impeller body 1 and hysteresis stops, reduced the impact of impeller when starting, can reduce impulsive force for whole drive system, reduce the electric motor starting electric current, prolong the service life of transmission system, also can reduce the impact of clothing and tear, reduce the wearing and tearing of clothing; The hysteresis restore funcitons of small wave wheel has prolonged the time of combination impeller rotation, has enlarged the contact-making surface of whole impeller and clothing, makes the stressed minimizing of clothing unit are, helps improving the wash degree and the washing uniformity; While is the small wave wheel of height suitably, and the winding and the knotting of clothing are reduced in the knotting center that can upset clothing, and is all favourable to reducing winding and improving wash degree.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
