Abstract
The utility model relates to a vibration damping device for a washing machine, which comprises a supporting rod , wherein a support seat is arranged at one end of the supporting rod, and the other end of the supporting rod is placed inside a sleeve; a bottom cover is arranged at the bottom of the sleeve; a vibration isolation spring and a support are arranged on the rod body, positioned inside the sleeve, of the supporting rod; a ripple rubber part is arranged at the end part of the rod body, positioned inside the sleeve, of the supporting rod; a first air chamber is formed between the ripple rubber part and the sleeve; a second air chamber is formed between the inside of the ripple rubber part and the bottom cover; flow blocking holes for connecting the first air chamber with the second air chamber are further formed in the ripple rubber part. According to the utility model, through the adoption of the technical scheme, the volume variation rate of the first air chamber and the second air chamber is changed through the movement of the ripple rubber part; proper damping force can be generated through adjusting the size of the flow blocking holes of the ripple rubber part; as the ripple rubber part is not in contact with the sleeve, the phenomenon that the damping of the traditional vibration damping device used for a long time is reduced or loses efficiency due to the abrasion and deformation of a vibration prevention rubber is effectively avoided.
Description
Technical field
The utility model relates to a kind of washing machine, is specifically related to a kind of washing machine vibration absorber.
Background technology
At present, the washing machine that people use, one end of its vibration absorber and casing connect, the bottom of the other end and outer barrel fixes, its structure is mainly by the formation sliding friction that moves up and down of vibration-proof rubber and damped sleeve, and compressed air is by the damping force of vibration-proof rubber restricted orifice, thereby play the effect of vibration damping.The shortcoming of this structure is: sliding friction meeting causes vibration-proof rubber abrasion deformation, and size decreases after vibration-proof rubber abrasion deformation, thereby causes damping force to reduce or lost efficacy, and causes washing machine occur in use for some time the dewatering phenomenon of abnormal vibrations.
Utility model content
The purpose of this utility model is to provide a kind of washing machine vibration absorber, and this vibration absorber can make still held stationary state of the dehydration of washing machine after long-play.
For achieving the above object, the utility model has adopted following technical scheme: comprise support bar, one end of described support bar is provided with the supporting seat being connected with casing of washing machine, the other end of support bar is placed in sleeve, the bottom of sleeve is provided with bottom, between sleeve and bottom, form airtight space, the body of rod that described support bar is positioned at sleeve is provided with isolation spring and bearing, one end and the sleeve of described isolation spring lean, the other end and the bearing of isolation spring lean, the rod end that described support bar is positioned at sleeve is provided with corrugated rubber part, described corrugated rubber part is positioned at the below of bearing, and the bottom of corrugated rubber part is resisted against on bottom, described corrugated rubber part can move up and down along the bar length direction of support bar, and form the first air chamber between described corrugated rubber part and sleeve, between corrugated rubber part inside and bottom, form the second air chamber, on described corrugated rubber part, be also provided with the restricted orifice that connects the first air chamber and the second air chamber.
Between described bearing and corrugated rubber part, be provided with band asphalt felt.
Described restricted orifice is arranged on the upper end of corrugated rubber part.
Described restricted orifice is symmetrical arranged two.
Between described corrugated rubber part and sleeve lining, leave gap.
As shown from the above technical solution, the utility model changes the volume change of the first air chamber and the second air chamber by the motion of corrugated rubber part, and the restricted orifice size of adjusting corrugated rubber part produces suitable damping force, because corrugated rubber part and sleeve are not in contact with one another, thus the deattenuation causing due to the abrasion deformation of vibration-proof rubber after effectively having avoided traditional vibration absorber because of long-time use or the phenomenon of inefficacy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of washing machine vibration absorber as shown in Figure 1, it is characterized in that: comprise support bar 1, one end of support bar 1 is provided with the supporting seat 2 being connected with casing of washing machine, the other end of support bar 1 is placed in sleeve 3, the bottom of sleeve 3 is provided with bottom 4, between sleeve 3 and bottom 4, form airtight space, the body of rod that support bar 1 is positioned at sleeve 3 is provided with isolation spring 5 and bearing 6, one end of isolation spring 5 and sleeve 3 lean, the other end of isolation spring 5 and bearing 6 lean, the rod end that support bar 1 is positioned at sleeve 3 is provided with corrugated rubber part 7, corrugated rubber part 7 is positioned at the below of bearing 6, and the bottom of corrugated rubber part 7 is resisted against on bottom 4, corrugated rubber part 7 can move up and down along the bar length direction of support bar 1, and between corrugated rubber part 7 and sleeve 3, form the first air chamber 8, between corrugated rubber part 7 inside and bottom 4, form the second air chamber 9, on corrugated rubber part 7, be also provided with the restricted orifice 10 that connects the first air chamber 8 and the second air chamber 9.
Further, between bearing 6 and corrugated rubber part 7, be provided with band asphalt felt 11.Arranging with asphalt felt is the voice producing when reducing air by restricted orifice.
Further, restricted orifice 10 is arranged on the upper end of corrugated rubber part 7.
Further, restricted orifice 10 is symmetrical arranged two.
Further, between corrugated rubber part 7 and sleeve 3 inwalls, leave gap.
In sum, the utility model changes the volume change of the first air chamber and the second air chamber by the motion of corrugated rubber part, and the restricted orifice size of adjusting corrugated rubber part produces suitable damping force, because corrugated rubber part and sleeve are not in contact with one another, thereby the deattenuation having caused due to the abrasion deformation of vibration-proof rubber after effectively having avoided traditional vibration absorber because of long-time use or the phenomenon of inefficacy, its dehydration still can even running after long-time use can to guarantee washing machine.
Above-described embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
