Abstract

The utility model discloses a suspension spring used for a drum washing machine, which primarily relates to a drum washing machine casing and a drum assembly. A hook is arranged on the upper part of the suspension spring, which is suspended at the upper corner on the inner side of the casing having a cushion block; the lower part of the suspension spring is a semi-closed hook which is suspended in the lifting hole of a drum assembly; the lower part of the drum assembly is connected with the drum washing machine casing through a shock absorber. The suspension spring is characterized in that the hook is semi-circular; and the corresponding support cushion of the suspension spring is cambered; after the suspension spring is assembled, the suspension hook rotates in the support cushion of the suspension spring. After the suspension spring involved in the technical proposal of the utility model is adopted, the upper hook of the suspension spring contacts the support cushion of the suspension spring of the casing in the way that the joint of the upper hook and the support cushion is cambered. When the suspension spring moves, the suspension spring rotates around the support cushion of the suspension spring with small friction. When the washing machine dewaters clothes, the vibratory force transferred to the casing is significantly improved. Accordingly, the suspension spring has the significant effect of reducing shock and noise.

Description

The spring that hangs that is used for roller washing machine

Technical field

The utility model relates to a kind of part of washing machine, and the roller washing machine that relates in particular to a kind of effectively shock dropping noise abatement is with hanging spring.

Background technology

Along with the continuous development of science and technology, as electric product indispensable in the civilian household appliances, washing machine is also constantly weeded out the old and bring forth the new.Washing machine in the market is by structure and mode of washing classification, roughly can be divided into: pulsator washing machine, tumbling-box washing machine, agitator type washing machine, jet washing machine, spray-type washer and oscillatory type washing machine, other washing machine wash degree is higher, clothing weares and teares still less and wherein compare to roller washing machine especially, more economize on water, economize on electricity and save washing powder, beginning more and more is subjected to consumer's favor.

At present, roller washing machine generally all is to hang spring by several to cooperate damper to be used for reaching support and damping purpose to the washing machine drum assembly simultaneously.As shown in Figure 1 to Figure 3 be the A part amplification effect schematic diagram of Fig. 1 after overall structure schematic diagram, the appearance assumption diagram that hangs spring and the assembling of existing roller washing machine finished.As seen from the figure, roller washing machine adopts a plurality of straight hook-shaped spring 1a that hang that the tub assembly 2 of washing machine is hung in the case shell 3.Particularly, hang spring 1a top and have hook 11, be suspended on angle on the inboard that is provided with on the cushion block 5a case shell; Hang spring 1a bottom and then be semi-closure crotch 12, collude in the lifting hole(eyelet) 21 that is hung in tub assembly 2, tub assembly 2 bottoms also join by damper 4 and case shell 3.Wherein, prior art hang spring 1a and case shell 3 contact portions, promptly linking up with 11 partial shapes is the right angle.When washing machine work generation clothing is uneven, tub assembly can produce left and right rocking, and owing to hang the restriction of spring 1 angle, hanging spring 1a moves dumb in cushion block 5a, be easy to vibration transfer with tub assembly 2 to case shell 3, cause bigger vibrating noise, properties of product are had a greatly reduced quality, and can't satisfy users' needs.

Summary of the invention

At above-mentioned the deficiencies in the prior art, the purpose of this utility model is: a kind of spring that hangs that is used for roller washing machine is provided, solves the excessive problem of vibration of washing machine noise under the current washing state.

Purpose of design of the present utility model, its implementation be by:

The spring that hangs that is used for roller washing machine relates to the case shell and the tub assembly of roller washing machine, and the described spring top of hanging has hook, is suspended on angle on the case shell inboard that is provided with cushion block; Hang the spring bottom and then be the semi-closure crotch, collude in the lifting hole(eyelet) that is hung in tub assembly, the tub assembly bottom also joins by damper and case shell, it is characterized in that: described hook is for semicircle, and the corresponding spring supporting pad that hangs is a cambered surface, hang after spring assembling finishes the motion that in hanging the spring supporting pad, rotates of described hook.

Further, the terminal elongated end that is at least 5mm that leaves of described semicircle hook.

After using that technical solutions of the utility model are described and hanging spring, the spring supporting pad that hangs that hangs spring top hook and case shell of roller washing machine is that circular arc contact, when hanging the spring motion be around hang the rotation of spring supporting pad, rub less.During laundry machine dehydration, be delivered on the case shell vibration force be improved significantly, have the good result of tangible shock dropping noise abatement.

The specific embodiment

The purpose of hanging spring, feature and advantage that the utility model is used for roller washing machine will specifically describe in conjunction with respective drawings further by following preferred embodiment, to deepen the understanding to this case innovation essence.

As shown in Figure 4 and Figure 5, be schematic appearance after structural representation that hangs spring of the present utility model and assembling thereof are finished respectively.The spring that hangs shown in the figure equally generally is applicable to roller washing machine, and common roller washing machine adopts a plurality of springs 1 that hang that the tub assembly 2 of washing machine is hung in the case shell 3.Particularly, hang spring 1 top and have hook 11, be suspended on and be provided with angle on the case shell inboard of hanging spring supporting pad 5; Hang spring 1 bottom and then be semi-closure crotch 12, collude in the lifting hole(eyelet) 21 that is hung in tub assembly 2, tub assembly 2 bottoms also join by location, supporting role and the case shell 3 of damper 4.Wherein, as shown in Figure 4 hang spring 1, its hook 11 be semicircle arcuation design, and leaves the long elongated end 111 of 5mm at least endways, with guarantee assembling finish after in washing machine is loaded rinsing or dehydration greatly, link up with and avoid shaking the unfavorable condition that falls.The corresponding with it spring supporting pad 5 that hangs then also designs for cambered surface, hanging after spring assembling finishes thus, the hook 11 that hangs spring 1 curved surface of supporting pad 5 of can fitting fully, even tub assembly 2 is acutely shake in washing machine rinsing or dehydration, the hook that hangs spring 1 motion that also will in supporting pad 5, only rotate.Effectively reduce frictional force and wear intensity on the one hand, on the other hand, make the vibration force that is delivered on the case shell obviously weaken.

In conjunction with the detailed description of said structure feature in actual applications, this roller washing machine hang spring 1 top hook 11 and case shell 3 hang spring supporting pad 5 for circular arc contact, hang when spring 1 moves be around hang 5 rotations of spring supporting pad, rub less.During laundry machine dehydration, be delivered on the case shell 3 vibration force be improved significantly.Therefore, the roller washing machine of the utility model design hangs spring, has the good result of tangible shock dropping noise abatement.

Only being the advantageous applications example of technical solutions of the utility model in sum, is not to limit with this to hang the diversified damping project organization of spring.Therefore, all employing equivalents or equivalence are replaced and the technical scheme that forms, can realize all dropping on this patent purpose within the claimed interest field of the utility model.
