Embodiment
With reference to the accompanying drawings, the leg assembly to household appliances of the present invention is elaborated.As a reference, in explanation of the present invention, be example with the roller washing machine, the leg assembly of household appliances is described.
Fig. 3 demonstrates the sectional arrangement drawing of leg assembly of the present invention.Fig. 4 demonstrates the oblique view of the suspension lid of Fig. 3.Fig. 5 a demonstrates the oblique view of the suspension chassis upper side of Fig. 3.Fig. 5 b demonstrates the oblique view of the suspension chassis lower side of Fig. 3.
As shown in the figure, leg assembly of the present invention includes following structure substantially: leg axle 20, suspension lid (SUSPENSION CAP) 30, suspension chassis (SUSPENSION BASE) 40 and compression spring 50.
Above-mentioned leg axle 20 passes the through hole 10a on the body chassis 10 that is formed on roller washing machine, and the bottom of leg axle 20 is formed with head (HEAD) portion 20 of rubber material, and above-mentioned head 20 contacts are supported on and are provided with on the ground; Be formed with the lift span 30a that above-mentioned leg axle 20 is passed on the suspension of the above-mentioned own lubrification material lid 30, hang simultaneously and cover 30 top and the above-mentioned leg axles 20 of above-mentioned chassis 10 1 liftings that are arranged on above-mentioned chassis 10; Above-mentioned suspension chassis 40 is contained in the inside of above-mentioned suspension lid 30, hang the outer peripheral face that chassis 40 is arranged on above-mentioned leg axle 20 simultaneously, when above-mentioned suspension lid 30 carries out lifting, make the periphery outer peripheral face that hangs chassis 40 and hang and cover 30 inner peripheral surface and combine closely and slide; The outer peripheral face setting that above-mentioned compression spring 50 surrounds above-mentioned leg axle 20 forms, an end that compresses spring 50 simultaneously is arranged on the upper inside face of above-mentioned suspension lid 30, the other end is arranged on the annular projection 40a, when covering 30 liftings, above-mentioned suspension stretches the outstanding top that is formed on above-mentioned suspension chassis 40 of above-mentioned annular projection 40a.
Wherein, a side of above-mentioned suspension lid 30 is formed with blow vent (ORIFICE) 30b, and above-mentioned blow vent 30b discharges the compressed air that 30 inside are covered in suspension to the outside when the lifting of above-mentioned suspension lid 30.
In addition, be provided with spreader spring 60 in the periphery inboard groove 40b on above-mentioned suspension chassis 40, above-mentioned spreader spring 60 is used to provide the elastic force that the periphery that hangs chassis 40 is expanded laterally, can increase the periphery on above-mentioned suspension chassis 40 and hang the force of sliding friction that covers 30 inner peripheral surface.
On the one hand, leg assembly of the present invention with said structure can only be arranged on the drift angle in four drift angles on body chassis 10 of cylinder casing, also can be arranged on two drift angles of front face side or two drift angles of back side or two drift angles, and can all be arranged on four drift angles with mutual diagonal symmetry.
At this moment, 10 drift angle side is not installed the invention described above leg assembly and the leg assembly of prior art is installed on the chassis.
Below, the effect of leg assembly of the present invention with said structure is elaborated.
If the rotation owing to cylinder when the washing of carrying out roller washing machine and dehydration produces vibration, the body chassis 10 of then above-mentioned vibration by above-mentioned roller washing machine is delivered to hang and cover on 30, at this moment carries out corresponding lifting along with corresponding extent of vibration makes above-mentioned suspension cover 30 peripheral parts along leg axle 20.
At this moment, make to be arranged on above-mentioned suspension lid 30 and to be fixed on compression spring 50 between the suspension chassis 40 on the above-mentioned leg axle 20 and play cushioning effect vibration; Meanwhile, cover 30 periphery inner peripheral surface and the periphery outer peripheral face on above-mentioned suspension chassis 40 is combined closely along with the lifting of above-mentioned suspension lid 30 makes to hang, mutual fricative force of sliding friction plays the cushioning effect to vibrating.
Particularly, owing to the periphery that hangs chassis 40 is more combined closely at the inner peripheral surface of above-mentioned suspension lid 30, can further increase the force of sliding friction between above-mentioned suspension lid 30 and the suspension chassis 40 by the spreader spring 60 in the periphery inboard groove that is arranged on above-mentioned suspension chassis 40.
In addition, owing to make the air that 30 inside are covered in above-mentioned suspension be compressed and play air damping (AIRDAMPING) effect, so can increase exponentially cushioning effect to the vibration that produces on the roller washing machine.
That is to say, suspension lid 30 by constituting the leg assembly and the cushioning effect that hangs force of sliding friction between the chassis 40, compressed air that 30 inside are covered in above-mentioned suspension and compression spring 50 vibration of absorption system effectively make system stability, so can prevent to be formed with above-mentioned leg assembly roller washing machine move (walking) phenomenon, can mildly wash and dewater.
