Abstract
The invention discloses a shock absorber and a washing machine with the same. The shock absorber comprises an outer cylinder with a buffer cavity, and a piston rod. The front end of the outer cylinder is provided with a damping chamber which is provided with a protective cover. The piston rod passes through the protective cover and the damping chamber to enter the buffer cavity. The part of the piston rod, corresponding to the damping chamber, is provided with a damping ring. A plurality of oil cavities are evenly reserved in the damping ring. By the technical means of evenly reserving the oil cavities in the damping ring, the piston rod generates a large amount of heat during operating; when the temperature of the surface of the piston, in contact with the damping ring, rises, lubricating oil is separated from the surface, of a damping strip, in contact with the piston; and spare lubricating oil in the oil cavities is released continuously to keep the piston rod moist in contacting with the damping ring, so that operational stability and continuity of the shock absorber are improved and the service life of the shock absorber is prolonged.
Description
Technical field
The present invention relates to damper, particularly relate to a kind of damper and the washing machine of this damper is housed.
Background technology
Existing tumbling-box washing machine comprises the shell forming outward appearance, be arranged in this shell for depositing the wash bucket of slurry, rotatably to be arranged in this wash bucket and for washing clothing and the cylinder of dehydrating operations, be arranged on this wash bucket below and be connected to the drive motors of cylinder.Cross the shell of phosphatization, electrophoresis, spraying triple protection, and the huge centrifugal force that two pieces of heavy balance weights are used for producing when balancing drum rotates does repeating motion, adds that the acting in conjunction of washing powder and water makes clothes washing clean.It particularly, by the rotatable front surface being arranged on shell of door clothing put into or takes out, and the rotary shaft rack for back-up roller is arranged on after wash bucket, spring is fixed on shell on the top of wash bucket, and is arranged on the bottom of wash bucket for the damper that cylinder of decaying is delivered to wash bucket vibration.
When damper moves downward, need to strengthen damping, to eliminate amplitude, reduce pendulum spring because of the larger pulling force of the excessive generation of displacement, the damping moving downward increasing can be delivered to ground by the lower margin of washing machine shell, increase the frictional force on lower margin and ground, this mode is of value to machine even running simultaneously.But the lubricating oil direct spraying of damper on the piston rod or be nested with on the piston rod after carrying out immersion oil to amortisseur bar in prior art, piston rod can produce a large amount of heats in the course of the work, when temperature sharply goes up high, lubricating oil can be detached the contact surface of amortisseur bar and piston rod, cause insufficient lubrication, the friction of amortisseur bar and piston rod is sharply increased, even cause amortisseur bar damaged, damping is unstable at work to cause damper, and shorten the service life of damper, adding users use cost.
Therefore, prior art needs further improvement and develops.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of damper and the washing machine of this damper be housed, increase the stability of damper and continuity, prolongation damper service life prerequisite under, reduce the noise of damper operator.
For solving the problems of the technologies described above, the present invention program comprises:
A kind of damper for washing machine, it comprises one with the urceolus and the piston rod that cushion cavity, wherein, described outer cylinder front end is provided with a dampening chamber, described dampening chamber is configured with a protecting cover, described piston rod inserts in described buffering cavity through described protecting cover, described dampening chamber, and described piston rod, being provided with a damped ring with described dampening chamber corresponding position, described damped ring has been evenly arranged multiple oil storage space.
Described damper, wherein, described oil storage space is oil storage hole or oil storage tank.
Described damper, wherein, one end of described piston rod is provided with connector, described connector is provided with the first lining, and described first lining is equipped with the first silencing cover.
Described damper, wherein, one end of described urceolus is provided with the second lining, and described second lining is equipped with the second silencing cover.
A kind of washing machine, wherein, described washing machine is equipped with described damper.
A kind of damper provided by the invention and washing machine of this damper is housed, adopt the technological means being evenly arranged multiple oil storage space on damped ring, first by damped ring immersion oil, also store lubricating oil in oil storage space simultaneously, piston rod produces a large amount of heats in the course of work, when piston rod and damped ring contact surface temperature raise, lubricating oil can be detached the contact surface of amortisseur bar and piston rod, but the lubricating oil meeting continuous release for subsequent use of oil storage space out, piston rod is contacted with damped ring keep lubricating, thus reach the object of permanent lubrication, add stability and the continuity of damper operator, extend the service life of damper, reduce customer using cost, by the silencing cover of correspondence, reduce the noise of damper operator.

Fig. 2 is the cross-sectional view of damper in the present invention.
Detailed description of the invention
The invention provides a kind of damper and the washing machine of this damper is housed, for making object of the present invention, technical scheme and effect clearly, clearly, the present invention is described in more detail below.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The invention provides a kind of damper for washing machine, as shown in Figures 1 and 2, it comprises one with the urceolus 2 and the piston rod 3 that cushion cavity 1, and described urceolus 2 front end is provided with a dampening chamber 4, described dampening chamber 4 is configured with a protecting cover 5, described piston rod 3 inserts in described buffering cavity 1 through described protecting cover 5, described dampening chamber 4, and described piston rod 3 can move in described buffering cavity 1, thus the impulsive force in buffering washing machine running; Described piston rod 3 is being provided with a damped ring 7 with described dampening chamber 4 corresponding position, described damped ring 7 has been evenly arranged multiple oil storage space 8, at oil storage space 8 internal memory deposit oil, ensure that described piston rod 3 keeps continuous lubrication with described damped ring 7 contact surface, extend the service life of damper.
Further, described oil storage space 8 is oil storage hole or oil storage tank, reduces its difficulty of processing, saves manufacturing cost, and obvious oil storage hole or oil storage tank can adopt square opening, circular trough or other geometric formats.
In another preferred embodiment of the present invention, one end of described piston rod 3 is provided with connector 9, described connector 9 is provided with the first lining 10, and described first lining 10 is equipped with the first silencing cover 11.And one end of described urceolus 2 is provided with the second lining 12, described second lining 12 is equipped with the second silencing cover 13, thus reduces the noise of damper operator.
And damper of the present invention can be assemblied on washing machine and apply.
Certainly; more than illustrate and be only preferred embodiment of the present invention; the present invention is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the instruction of this description; made all equivalently to substitute, obvious variant, within the essential scope all dropping on this description, protection of the present invention ought to be subject to.
