Below with reference to Fig. 1-Fig. 2, the bump leveller for washing machine 200 according to embodiments of the present invention, wherein washing machine are described
200 include body 201, and this bump leveller can be used in washing machine 200 such as roller washing machine, the rolling in body 201
When cylinder 202 is in high-speed state, the vibration of roller washing machine can be effectively reduced.In the explained below of the application,
Illustrate as a example by roller washing machine by bump leveller.Certainly, those skilled in the art are appreciated that this suction
The device that shakes can be additionally used in other kinds of washing machine 200, and is not limited to roller washing machine.
As it is shown in figure 1, the bump leveller for washing machine 200 of embodiment according to a first aspect of the present invention, including body 1,
Multiple damping particles 2 and at least one elastic component.
Multiple damping particles 2 are located in body 1.The most in the example of fig. 1, body 1 is generally rectangular shaped, body 1
Inside limiting accommodating chamber, each damping particles 2 can be all formed as spherical, and multiple damping particles 2 are located at accommodating chamber
In, when washing machine 200 produces vibration, drive between damping particles 2 and damping particles 2 and damping particles 2 with
Inelastic collision between the inwall of body 1 and friction, consume vibrational energy with this, produces damping effect, to reach
The purpose of suppression washing machine 200 such as laundry drum machine vibration.It is to be appreciated that body 1 and damping particles 2
Shape and size can be arranged according to actual requirement, to have more preferable shock attenuation result.
Alternatively, body 1 can use the materials such as plastics, aluminium alloy or lucite to make, and damping particles 2 can use gold
Belong to material such as iron, steel, tungsten to make.Certainly, the invention is not restricted to this, damping particles 2 also can use rubber or bubble
Foam material is made.
Body 1 is suitable to be connected in body 201 by least one elastic component.With reference to Fig. 1, body 1 is by two bullets
Property part such as spring 3 is connected on the inwall of body 201, body 201 vibrate by spring 3 drive body 1 and
Damping particles 2 in body 1 vibrates,
The bump leveller for washing machine 200 according to embodiments of the present invention, by arranging multiple damping particles 2, can widen
The frequency band of bump leveller, two formants of suppression bump leveller, and can be by the vibrational energy of washing machine 200 by this bump leveller
Amount transfer so that bump leveller vibration acutely, exacerbates the motion of internally-damped particle 2, thus has preferably damping
Effect, and then efficiently reduce the vibration of washing machine 200 such as roller washing machine.
From figure 2 it can be seen that the vibration amplitude according to the bump leveller of the present invention is less, and compared with traditional bump leveller,
Restrained effectively two formants of bump leveller, thus widen the frequency band of bump leveller.
In one embodiment of the invention, the quality sum of body 1 and multiple damping particles 2 is m,
Wherein, m is configured to:
m=μM
Wherein, M is the quality of washing machine 200, and μ is mass ratio.
Owing to the mass M of washing machine 200 is it is known that pass through to choose suitable μ value in advance, according to above-mentioned relation Shi Ketong
Cross quality sum m being calculated body 1 and multiple damping particles 2.Alternatively, μ is 0.05～0.1.It is understood that
, the concrete quality of body 1 and multiple damping particles 2 can be arranged according to actual requirement, real preferably to meet
Border requirement.
Further, the rigidity of bump leveller is k,
Wherein, k is configured to:
k=mω2
Wherein, the intrinsic frequency of bump leveller is ω.
Now the quality of elastic component such as spring 3 is negligible, the quality sum of body 1 and multiple damping particles 2
M is the quality of bump leveller, and alternatively, the natural frequency ω of bump leveller is identical with the intrinsic frequency of washing machine 200, by
In the intrinsic frequency of washing machine 200 it is known that can be by being calculated rigidity k of bump leveller according to above-mentioned relation formula.
In one embodiment of the invention, elastic component is spring 3, and body 1 is suitable to be connected to machine by a spring 3
In body 201, wherein the rigidity of this spring 3 is rigidity k of bump leveller.It is to be appreciated that elastic component can be also elastic
Bellows (not shown).
Certainly, the invention is not restricted to this, in other embodiments of the present invention, spring 3 is multiple, and body 1
Being suitable to be connected in body 201 by multiple springs 3, the equivalent stiffness of the most multiple springs 3 should be equal to bump leveller
Rigidity k.
Alternatively, multiple springs 3 are sequentially connected in series and/or in parallel.It is to say, multiple springs 3 can be sequentially connected in series, or
Person's multiple spring 3 is in parallel, or some springs 3 in multiple spring 3 are connected, and other springs 3 are in parallel.
Specifically, illustrate as a example by body 1 is connected in body 201 by two springs 3.Wherein, when two
When spring 3 is connected, these two springs 3 need to meet:
Wherein, k1And k2Being respectively two spring 3 rigidity, k is the rigidity of bump leveller.
When two springs 3 are in parallel, these two springs 3 need to meet:
k=k1+k2
Wherein, k1And k2Being respectively two spring 3 rigidity, k is the rigidity of bump leveller.
Preferably, spring 3 is two, and the two ends of body 1 are connected in body 201 by two springs 3 respectively.
With reference to Fig. 1, the two ends, left and right of body 1 are connected in body 201 by two springs 3 respectively, and body 1 can be in left and right
Side moves up.Alternatively, the equal stiffness of these two springs 3.
The washing machine 200 of embodiment according to a second aspect of the present invention, including: body 201 with according to the present invention above-mentioned first
The bump leveller for washing machine 200 of aspect embodiment, in wherein bump leveller is located at body 201.
The most in the example of fig. 1, in body 201, limit receiving space, in cylinder 202 is located at receiving space and position
In the bottom in receiving space, bump leveller is located in accommodating space and is positioned at the top of cylinder 202, the left and right two of body 1
End is connected in body 201 by two springs 3 respectively.
