Embodiment
The present invention is described in detail below in conjunction with each mode of execution shown in the drawings; but should be noted that; these mode of executions are not limitation of the present invention; those of ordinary skills all belong within protection scope of the present invention according to these mode of execution institute work energy, method or structural equivalent transformation or alternative.
Shown in Fig. 1 ~ 2, refrigerator of the present invention comprises the housing that forms the refrigerator storage space, the door body that is used for opening or sealing above-mentioned storage space, and the interior volume that refrigerator shell surrounds also comprises compressor, compressor carried out damping pad, and the dunnage of carrying compressor and damping pad of vibration damping.The elasitic layer 11 that damping pad 100 comprises damping layer 10, is assembled together with damping layer 10.Wherein elasitic layer 11 comprises body 111 and is arranged at body 111 lip-deep collars 1111, and collar 1111 is cylindrical, and it is connected for being fixed with compressor.And the top of collar 1111 has flange 1112, and damping layer 10 is arranged on the surface of elasitic layer 11 at collar 1111 places, and it closes by pressure viscosity or mucilage binding technology and elasitic layer 11 link together and form an integral body.
Above-mentioned damping layer 10 is the first compressive plane 101 with the surface of contact of elasitic layer 11, and damping layer 10 carries out seamless the contact with elasitic layer 11 on the first compressive plane 101.And damping layer 10 with the Vertical direction of the first compressive plane 101 on, in the elastic strain scope, can carry out without restrictions free deformation, thereby by self elastic strain and the loss of stress deformation produce power, the vibration that produces in the time of will be from compressor operating consumes.Usage requirement according to different operating modes, the material of damping layer 10 can be selected from: the materials such as rubber, perforate rubber, damping alloy, and the area of the thickness of damping layer and the first compressive plane 101 is then tried to achieve by maximum static deflection and the dynamic modulus of elasticity of selected material.
Shown in Fig. 3 (a) ~ 4, damping layer 10 can be a kind of pure damping material, simultaneously as another kind of mode of execution, above-mentioned damping layer 10 is interior can also to arrange hole 102 and/or hard particles 103, when damping layer 10 absorbs vibration deformation, to produce more extraneous vibration, increase energy dissipation, transmit thereby reduce vibration, reduce noise.This is because hole, the hard particles of damping layer 10 interior increases can need more energy when damping layer vibrates, thereby have produced larger cushioning effect.
Also be formed with the cavity 1113 of through shaft neck 1111 and body 111 in the elasitic layer 11, this cavity 1113 is configured to the circular cavity structure, so be provided with to be beneficial to and increase damping pad 100 perpendicular to the area on the first compressive plane 101 directions, thereby strengthen cushioning effect.Correspondingly, be provided with the fixing column that matches with cavity 1113 on the dunnage, damping pad 100 is set on the fixing column by cavity 1113.Therefore, the size of cavity 1113 depends on the diameter of fixing column.
Cooperate with reference to shown in Figure 5, preferably, the body 111 of above-mentioned elasitic layer 11 is trapezoidal, said trapezoidal referring to herein, and the cross section of body 111 is trapezoidal, and this trapezoid cross section and above-mentioned the first compressive plane 101 are perpendicular.Collar 1111 is arranged at the upper bottom surface of trapezoidal body 111, namely goes up on the compressive plane d21.So arranging, is to consider on the direction perpendicular to the first compressive plane 101, is compressed the effect of machine deadweight and vibrational excitation, and deformation can occur elasitic layer 11, thereby the energy of vibration is maximized dissipation.But compressor is under the effect of electromagnetic force, and its internals can be along with the exciting force fast rotational, thereby produces periodic moving seesaw-type moment in the both sides of compressor.Be configured to trapezoidal elasitic layer and not only can bear the compression-type vibration force, can bear equally moving seesaw-type shearing type moment, the rotatory force of compressor is inhibited in elasitic layer.Thereby avoided compressor transmitting vibrations on the fixing column of above-mentioned dunnage, intercepted the vibration of compressor in a plurality of degrees of freedom directions, effectively suppressed the generation of noise.
As another preferred embodiment, the body 111 of above-mentioned elasitic layer 11 also can be configured to " M " type, and in like manner, said " M " type refers to that also the cross section of body 111 is " M " type herein, and the cross section of " M " type and above-mentioned the first compressive plane 101 are perpendicular.The formation in " M " type cross section is namely offered two grooves at the bottom surface of above-mentioned trapezoidal elasitic layer 11, has so further increased the quantity of free surface d1, has improved effectiveness in vibration suppression.
As shown in Figure 6, further, damping layer 10 forms surface of contact 104 with the contact segment of compressor, because the variation of the exciting force during the compressor rotary work, the stress that surface of contact 104 is subject to also changes, this has caused stressed inhomogeneous of damping layer 10, therefore so that damping layer can't consume the vibration that compressor produces to greatest extent.Therefore, the opposite side of the damping layer 10 relative resilient layers 11 of above-mentioned damping pad 100 also is provided with restraint layer 12.This restraint layer 12 is made of the larger material of hardness, thereby makes its nonelastic deformation when compressor operating.Preferably, the material of restraint layer 12 is selected from rubber or plastics, and the area of restraint layer 12 and shape are corresponding respectively with area and the shape of surface of contact 104.
Restraint layer has increased the area on the surface of the vibration of transmitting the compressor generation, thereby so that damping layer can consume the vibration that compressor produces to greatest extent, has increased the damping effect of damping layer.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned example embodiment, and in the situation that does not deviate from spirit of the present invention or essential characteristic, can realize the present invention with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims rather than above-mentioned explanation, therefore is intended to include in the present invention dropping on the implication that is equal to important document of claim and all changes in the scope.Any reference character in the claim should be considered as limit related claim.
In addition, be to be understood that, although this specification is described according to mode of execution, but be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, and the technological scheme among each embodiment also can through appropriate combination, form other mode of executions that it will be appreciated by those skilled in the art that.
