Pass through the setting of throttling element, with the change of plunger stroke in sleeve, the number of damping hole in the open state
Amount is corresponding to be changed, and then damping force also changes accordingly.Specifically, the fluid when plunger does compression movement, in liquid capsule
Flowed to second chamber, while damping hole in the open state is fewer and fewer so that fluid enter the difficulty of second chamber by
Cumulative big, the fluid in first chamber enters second chamber and needs bigger power, so that the damping force for generating damper is bigger.
When plunger does extensional motion, the fluid of second chamber is flowed into liquid capsule, while damping hole in the open state is increasingly
More, so that fluid is gradually reduced by the difficulty that damping hole enters in liquid capsule, the fluid of second chamber is quickly reduced, so that the
Negative pressure in two chambers increases, and causes the fluid in second chamber to enter the damping force that liquid capsule is subject to and becomes larger.Therefore, of the invention

Flowing between second chamber avoids keeping the fit clearance between pipe structure and plunger excessive due to machining accuracy, abrasion etc.,
The problem of damping force of damper substantially reduces caused by fluid is flowed by the gap in turn appearance.On the other hand, may be used also
To realize that damper provides different damping forces under different shock conditions.Specifically, when washing machine generates smaller tremors, it is close
Sealing can be such that sub-fraction fluid enters in annular groove by way of sliding in annular seal groove, and then reduce fluid
The resistance back and forth flowed in liquid capsule and second chamber reduces so that the damping force that damper provides in smaller tremors also reduces
The vibration of cylindric washer is transmitted on washing machine shell by damper, guarantees running smoothly for washing machine, noise is small.In washing machine
It is big due to shaking when generating big shake, shake speed fastly, sealing element does not move substantially relative to annular seal groove at this time, is equivalent to close

It connects.The open end (right end of liquid capsule 14 shown in Fig. 3) of liquid capsule 14 is hermetically closely connect with the second end of plunger 12.Throttling
Part 13 is set to the closed end of liquid capsule 14 including pedestal 131 and the pipe structure 132 being fixedly connected with pedestal 131, pedestal 131,
Pipe structure 132 is inserted into second chamber 122.Several damping holes 133, the inner cavity of liquid capsule 14 and/or are provided in pipe structure 132
By injection hydraulic oil 4, when plunger 12 slides in the first chamber 112 of sleeve 11, several damping holes in two chambers 122
A part of damping hole 133 in 133, which is in, opens/closes state, and hydraulic oil 4 can pass through damping hole in the open state
133 back and forth flow in liquid capsule 14 and second chamber 122.Preferably, liquid capsule 14 is made by elastic material, such as polyurethane,

The inner wall of circumferential outer rim and first chamber 112 matches, and if first chamber 112 is cylindrical cavity, pedestal 131 is cylinder
Structure, and the cross-sectional diameter of cylindrical structure cross-sectional diameter and cylindrical cavity is roughly equal.
From the description above it can be seen that on the one hand, since the open end of liquid capsule 14 is fixedly connected with plunger 12, liquid capsule 14
Closed end be fixedly connected with sleeve 11, therefore, plunger 12 move back and forth during, plunger 12 can stretch or compress liquid capsule
14, in turn, liquid capsule 14 can provide an elastic damping power, as plunger 12 deviates the increasing of the stroke of equilbrium position in sleeve 11
Greatly, the elastic damping power being subject to also is increasing, and enhances the damping effect of damper 1.Importantly, on the other hand, by
In being provided with throttling element 13, and the insertion second chamber 122 of pipe structure 132 of throttling element 13 in liquid capsule 14, therefore, in plunger
During 12 move back and forth, the number of damping hole 133 in the open state is changing at any time, and then passes through damping hole 133

Between sliding more smoothly and stablize, avoid since throttling element 13 is during the work time due to there is the pipe structure of throttling element 13
The case where damper 1 fails caused by 132 appearance biasing phenomenons.
In other words, compared to the existing damper of rotating drum washing machine for carrying out damping using frictional force, of the invention subtracts
The damping force of the generation of device 1 damping force inconstant at any time is shaken, is changed with the amplitude of vibration, the vibration of vibration
Width is bigger, and the damping force for resisting the vibration that damper 1 generates is also bigger.And damper 1 of the invention can't be because of
Phenomena such as abrasion and the problem of cause damper 1 to fail after a period of operation, hindered in the prior art to solve
The problem of Buddhist nun's power is unable to consecutive variations substantially enhances the damping effect of damper 1, substantially improves user and uses laundry drum
Machine makes user experience.
Herein it should also be noted that, in the present embodiment with no restriction to the quantity and diameter of damping hole 133, for difference
For the damper 1 of model, the quantity and diameter of damping hole 133 are not quite similar.For example, for smaller damper
For 1, the diameter of damping hole 133 can be in the thickness section of a few tenths of a mm to several millimeters；And the damper 1 of relatively large-scale
It says, the diameter of damping hole can be in several millimeters to more than ten millimeters of thickness section.
Those skilled in the art will also be appreciated that the preferred arrangement of above-mentioned damping hole 133 is used merely to explain
The principle of the present invention, it is not intended that with limit the scope of the invention, under the premise of without departing from the principle of the invention, this field
Technical staff can also carry out any form of adjustment to above-mentioned set-up mode, to adapt to more specifical application.Example
Such as, the section of damping hole 133 can also be ellipse or rectangle；Pedestal 131 and pipe structure 132 can be consolidated by the way of being spirally connected
Fixed connection；Angle between the axis of damping hole 133 and the axis of pipe structure 132 can be any angle, such as damping hole 133
The angle of axis and the axis of pipe structure 132 in horizontal direction to the left is 45 °.
With further reference to Fig. 3, in a kind of more preferably embodiment, damper 1 further includes at least one elastic component,
At least one elastic component is arranged in a manner of preventing throttling element 13 mobile.Preferably, two elastic components can be set in damper 1,
Respectively the first elastic component 15 and the second elastic component 16, and the first elastic component 15 and the second elastic component 16 can be set to it is in office
The meaning moment all has compressive deformation.Orientation as shown in Figure 3, the both ends of the first elastic component 15 right circular with pedestal 131 respectively
The second end of face and plunger 12 is connected, the both ends of the second elastic component 16 respectively with the right end annular surface of pipe structure 132 and
The right side of two chambers 122 is connected.Specifically, elastic component can be spring, leaf spring or elastomer block.
Have the advantage that in this way: on the one hand, plunger 12 is when relative sleeve 11 moves back and forth, 15 He of the first elastic component
Second elastic component 16 can effectively prevent throttling element 13 mobile with plunger 12, especially when plunger 12 does extensional motion, the
One elastic component 15 and the second elastic component 16 all have the set-up mode of compressive deformation at any time, stop throttling element 13 always
In fixed position, and then the presence due to throttle resistance is avoided, throttling element 13 arbitrarily stops in liquid capsule 14 and leads to damper 1
Damping effect the phenomenon that being deteriorated.On the other hand, the first elastic component 15 and the second elastic component 16 all have at any time
The set-up mode of compressive deformation, the elastic force for generating the first elastic component 15 and the second elastic component 16 are further offset
The vibration that washing machine generates, further enhances the damping effect of damper 1, this effect when plunger 12 does compression movement especially
Obviously.
Certainly, the quantity of elastic component and set-up mode and not exclusive, those skilled in the art can also make it accordingly
Adjustment, so that it adapts to more specifical application scenarios.If elastic component can also only be arranged one, such as only retain the first reality
The first elastic component 15 in mode is applied, or only retains the second elastic component 16 in the first embodiment, such set-up mode
The effect for preventing throttling element 13 that from can further offsetting vibration with the movement of plunger 12 and elastic force can equally be completed.
Referring to shown in Fig. 4 and Fig. 5, Fig. 4 is partial enlargement diagram of the Fig. 3 at A；Fig. 5 is of the invention is used for
The schematic diagram of second of embodiment of the sealing element of the damper of roller washing machine.
As shown in figure 4, in a kind of more preferably embodiment, in order to further increase the damping effect of damper 1,
Sealing element 17 is also provided between throttling element 13 and plunger 12, sealing element is slidably set to throttling element.
Preferably, sealing element 17 is O-ring seal, and is provided with length greater than O-ring seal in the pipe structure 132 of throttling element 13
The first annular seal groove 134 of diameter, O-ring seal are embedded in the first annular seal groove 134 and can opposite first rings
Shape seal groove 134 slides axially along pipe structure 132.
By foregoing description it can be seen that, on the one hand, the setting of O-ring seal may be implemented in pipe structure 132 and plunger 12
Sealing between wall, it is ensured that hydraulic oil 4 only passes through damping not by the gap flowing between plunger 12 and pipe structure 132
Flowing between liquid capsule 14 and second chamber 122 is realized in hole 133, avoid making due to machining accuracy, abrasion etc. pipe structure 132 and
Fit clearance between plunger 12 is excessive, and then hydraulic oil 4 passes through the damping force of damper 1 caused by the gap is flowed significantly
The problem of reduction, occurs, and further promotes the damping effect of damper 1.On the other hand, the setting of O-ring seal can also be realized
Damper 1 provides different damping forces under different shock conditions.Specifically, when washing machine generates smaller tremors, O-shaped sealing
Circle can make sub-fraction hydraulic oil 4 enter the first annular sealing by way of sliding in first annular seal groove 134
134 in slot, and then resistance when hydraulic oil 4 back and forth flows in liquid capsule 14 and second chamber 122 is reduced, so that in smaller tremors
When the damping force that provides of damper 1 also reduce, the smaller tremors for reducing roller 3 is transmitted on washing machine shell by damper 1, is protected
Card washing machine runs smoothly, and noise is small.It is big due to shaking when washing machine generates big shake, shake speed fastly, O-shaped sealing at this time
Circle does not move substantially relative to first annular seal groove 134, is equivalent to O-ring seal and is fixedly connected on first annular seal groove
In 134, the resistance that hydraulic oil 4 back and forth flows in liquid capsule 14 and second chamber 122 is basically unchanged, so that the damping in big vibration
Device 1 provides relatively large damping force, quickly reduces the vibration that washing machine generates.
Obviously, the form of sealing element 17 and setting position are not unalterable, as shown in figure 5, can also be in the second chamber
The second annular seal groove 123 that annular is opened up on the inner wall of room 122, sealing element 17 is embedded in second annular seal groove 123
In, and several keyways 124 are opened up in the second annular seal groove 123, there is washing machine when generating smaller tremors more
Hydraulic oil 4 can flow into the second annular seal groove 123 and keyway 124, further decrease hydraulic oil 4 in liquid capsule 14 and the second chamber
Resistance when back and forth being flowed in room 122.The form of sealing element 17 can also be any other form, as long as its satisfaction can be by column
The length of clearance seal and annular seal groove between plug 12 and throttling element 13 is in the big condition of axial length than sealing element
Can, such as sealing element 17 can also be sealing ring.
To the damper for roller washing machine of the invention below with reference to Fig. 3 and for when washing machine generates big vibration
1 working principle is described briefly.
By shown in the orientation Fig. 3, when 12 stress of plunger is slided to the left, 14 volume of liquid capsule becomes smaller, and is in and beats on throttling element 13
The damping hole 133 of open state is reduced, and hydraulic oil 4 is squeezed, and the inner cavity of liquid capsule 14 generates positive pressure, while sealing element 17 is first
Annular seal groove 134 is relatively fixed, makes 4, hydraulic oil to flow by damping hole 133 in the open state to second chamber 122
Dynamic, hydraulic oil 4 generates damping force to the right, while the first elastic component 15 and second to plunger 12 when flowing to second chamber 122
Elastic component 16 is generated biggish elastic force by compression, and the movement of plunger 12 to the left is slowed down together with damping force, plays damping
Effect；When 12 stress of plunger is slided to the right, the volume of second chamber 122 and liquid capsule 14 all becomes larger, and is in and beats on throttling element 13
The damping hole 133 of open state increases, and hydraulic oil 4 is stretched, and the inner cavity of liquid capsule 14 generates negative pressure, while sealing element 17 is first
Annular seal groove 134 is relatively fixed, enters hydraulic oil 4 just through damping hole 133 in the inner cavity of liquid capsule 14, hydraulic oil 4 is flowing
Damping force to the left is generated to plunger 12 when to the inner cavity of liquid capsule 14, the movement of plunger 12 to the left is slowed down, plays damping effect,
The first elastic component 15 and the second elastic component 16 prevent throttling element 13 with plunger due to still having elastic force with compressive deformation simultaneously
12 move right.
Referring again to Fig. 1, another aspect of the present invention provides a kind of washing machine comprising shell 2 and is set to shell
Roller 3 in 2, roller 3 are supported on shell 2 by two dampers 1, it is preferable that two dampers 1 are this above-mentioned hair
The bright damper 1 for roller washing machine.Certainly, setting quantity of the damper 1 in roller washing machine is not unalterable,
Three, four or more dampers 1 are also provided in roller washing machine, and at least one in these dampers 1
