A compressor 100 according to an embodiment of the present invention will be described below with reference to fig. 1 to 4, and the compressor 100 may be used in a refrigerating apparatus.
As shown in fig. 1 to 2, a compressor 100 according to an embodiment of the present invention includes a housing 10 and a plurality of foot pads 30. The casing 10 is provided with an exhaust port, and when the compressor 100 operates, the compressor 100 compresses the refrigerant, and after the compression of the refrigerant is completed, the refrigerant is discharged from the exhaust port of the casing 10. The bottom of the casing 10 is provided with a mounting seat 40, and the mounting seat 40 supports the compressor 100.
As shown in fig. 1 to 3, a plurality of metal sheets 20 are respectively provided on the outer circumferential wall of the case 10, and natural frequencies of at least two metal sheets 20 are different. Specifically, the compressor 100 has a plurality of metal sheets 20 provided on the outer peripheral wall of the casing 10, and when the compressor 100 is operated, the compressor 100 generates vibration, which is transmitted to the plurality of metal sheets 20 on the outer peripheral wall thereof through the casing 10. Under the effect of vibration, elastic deformation can take place for a plurality of sheetmetals 20, and the vibration kinetic energy that a plurality of sheetmetals 20 produced compressor 100 through the elastic deformation of self is consumed to can play absorbing effect, can prevent that the vibration that compressor 100 produced from transmitting to the sheet metal component, can reduce compressor 100's operating noise from this. Alternatively, the plurality of metal sheets 20 may be fixed to the outer circumferential wall of the housing by welding.
Since the natural frequencies of at least two metal sheets 20 are different, the width of the absorbed vibration frequency of the metal sheets 20 can be increased. It can be understood that, since the compressor 100 generates vibration of various frequencies during operation, when the natural frequency of the metal sheet 20 is the same, the metal sheet 20 can absorb vibration of only one frequency, which can seriously affect the vibration absorbing effect of the metal sheet 20. When the natural frequencies of at least two metal sheets 20 on the housing 10 are different, the metal sheets 20 can absorb the vibration of different frequencies, so that the damping effect of the metal sheets 20 can be improved.
As shown in fig. 1 to 3, a plurality of foot pads 30 are respectively disposed on the mounting base 40, and when the compressor 100 operates, vibration generated by the compressor 100 may be transmitted to the foot pads 30 on the mounting base, and the foot pads 30 may buffer the vibration, so that operating noise of the compressor 100 may be reduced. As shown in fig. 2, each of the foot pads 30 includes a container 310, a piston 320, and a piston rod 330, the piston rod 330 being provided on the piston 320 with an upper portion of the piston rod 330 penetrating the container 310 to be fixed on the mounting seat 40, the piston 320 being located in the container 310 with an outer circumferential wall of the piston 320 cooperating with an inner circumferential wall of the container 310 to define a closed compression space. When the compressor 100 vibrates, the piston 320 moves up and down in the container 310 by the vibration. The compression space is filled with a liquid 350, and the piston 320 is in contact with the liquid level of the liquid 350. The liquid 350 may act as a support for the piston 320 when the piston 320 is depressed. The elastic body 340 is disposed in the liquid 350, and when the piston 320 applies downward pressure to the liquid 350, the elastic body 340 can contract, thereby achieving a shock absorption effect.
Specifically, when the compressor 100 is operated, the compressor 100 vibrates to generate a downward dynamic impact load, the dynamic impact load acts on the piston rod 330 of the foot pad 30, the piston rod 330 drives the piston 320 to move downward, and the piston 320 applies a downward pressure to the liquid 350. Because liquid 350 can not compress, consequently can be in the twinkling of an eye transmit pressure to the elastomer 340 in liquid 350, the elastomer 340 atress and shrink, absorb the momentum of vibration and convert the heat into, the heat spreads out through the lateral wall of container 310 to can play absorbing effect, can prevent that the vibration that compressor 100 produced from transmitting to the sheet metal component, can reduce compressor 100's operating noise from this.
It can be understood that a plurality of foot pads 30 may be disposed on the mounting seat 40 of the compressor 100, and when the compressor 100 generates vibration, the plurality of foot pads 30 simultaneously receive downward pressure and simultaneously buffer the vibration, so that the efficiency of buffering the vibration may be improved, and the operating noise of the compressor 100 may be better reduced.
According to the compressor 100 of the embodiment of the present invention, by providing the plurality of metal sheets 20 and the plurality of foot pads 30, when the compressor 100 operates, vibration generated from the compressor 100 is transmitted to the plurality of metal sheets 20 on the outer circumferential wall thereof through the housing 10. Under the effect of vibration, a plurality of sheetmetals 20 can take place elastic deformation, and a plurality of sheetmetals 20 consume the vibration kinetic energy that compressor 100 produced through the elastic deformation of self to can play absorbing effect. By setting the natural frequencies of at least two metal sheets 20 to be different, the width of the vibration frequency absorbed by the metal sheets 20 can be increased, and the damping effect of the metal sheets 20 can be improved. Further, the vibration generated by the compressor 100 forms a downward dynamic impact load to act on the foot pads 30, the elastic body 340 in the liquid 350 is stressed and contracted, the momentum of the vibration is absorbed and converted into heat, and the heat is transmitted out through the side wall of the container 310, so that the vibration absorption effect can be achieved, the vibration generated by the compressor 100 can be prevented from being transmitted to the sheet metal parts, and the working noise of the compressor 100 can be reduced.
According to some embodiments of the present invention, the natural frequencies of the plurality of metal sheets 20 are different, so that the damping effect of the metal sheets 20 can be maximized. When the compressor 100 works, the plurality of metal sheets 20 with different natural frequencies respectively correspond to the vibrations with different frequencies generated by the compressor 100, and each metal sheet 20 can consume the kinetic energy of the vibration with the corresponding frequency through the elastic deformation of the metal sheet 20, so that a good damping effect can be achieved, and the working noise of the compressor 100 can be reduced.
In some embodiments of the present invention, the plurality of metal sheets 20 have different lengths and the same thickness, so that the plurality of metal sheets 20 absorb different frequencies of vibration, thereby improving the damping effect of the metal sheets 20. In one specific example of the invention, the constant section metal sheet 20 of uniform material has a natural frequency of
Where ρ is the density of the metal sheet, A is the cross-sectional area, E is the modulus of elasticity, and I is the moment of inertia of the cross-section about the neutral axis.
Where b is the width of the cross-section and h is the length of the cross-section.
Where λ can be given by the following equation:
ch(λ1)cos(λ1)＝-1
as can be seen from the above formula, when the metal sheets 20 have the same thickness and different lengths, and the inertia distances I of the metal sheets 20 are different, the natural frequencies of the metal sheets 20 are also different, so that the metal sheets 20 can absorb the vibrations of different frequencies, thereby improving the damping effect. Further, the widths of the plurality of metal sheets 20 are the same, so that the natural frequencies of the plurality of metal sheets 20 can be different, and the damping effect can be improved. It should be noted that the greater the structural parameters (length, width, thickness, etc.) of the metal sheet 20, the wider the frequency range of the vibration that can be absorbed by the metal sheet 20, and the better the damping effect.
As shown in fig. 1, according to some embodiments of the present invention, a plurality of metal sheets 20 are disposed on both sides of a central axis of a housing 10 at intervals in an up-down direction, respectively, so that vibrations in a plurality of frequency bands can be absorbed. Specifically, the compressor 100 may generate vibrations of various frequencies during operation, and the plurality of metal pieces 20 may be disposed in the vertical direction of the outer circumferential wall of the compressor 100 according to the frequency distribution of the vibrations, so that the metal pieces 20 in different directions in the vertical direction may cancel the vibrations of different frequencies, thereby effectively reducing the operation noise of the compressor 100.
As shown in fig. 3, in some embodiments of the present invention, a plurality of metal sheets 20 are disposed on both sides of the central axis of the housing 10 at intervals in the circumferential direction, so that vibrations in a plurality of frequency bands can be absorbed. Specifically, a plurality of metal sheets 20 may be provided at intervals in the circumferential direction of the outer circumferential wall of the compressor 100 according to the frequency distribution of the vibration, and the metal sheets 20 in different directions in the circumferential direction may cancel the vibration of different frequencies, so that the operating noise of the compressor 100 may be effectively reduced.
It should be noted that, because the plurality of foot pads 30 are disposed at the bottom of the compressor 100, the plurality of foot pads 30 can effectively buffer the vibration generated by the compressor 100, so as to ensure the stability of the compressor 100 during operation. Therefore, the metal plate 20 on the housing 10 may not be symmetrically disposed with respect to the central axis thereof, and may be disposed at any position on the outer circumferential wall of the housing 10 according to the installation space and design requirements.
As shown in fig. 3, in some embodiments of the present invention, the plurality of metal sheets 20 distributed on the same side of the central axis of the housing 10 are uniformly spaced in multiple rows and multiple columns, so that the difficulty in installing the metal sheets 20 can be reduced, and the assembly efficiency can be improved.
As shown in fig. 3, according to some embodiments of the present invention, the distance between adjacent metal sheets 20 of the plurality of metal sheets 20 is kept constant, so that the metal sheets 20 can be more regular respectively on the premise of being able to absorb shock. It is understood that the up-down interval and the circumferential interval between the plurality of metal sheets 20 may be different, and may be selectively set according to the actual vibration frequency distribution of the compressor 100 and the installation space of the compressor 100.
As shown in fig. 2, according to some embodiments of the present invention, a plurality of elastic bodies 340 are disposed in the liquid 350, so as to achieve a better shock absorption effect. Specifically, when the vibration generated by the compressor 100 forms a downward dynamic impact load on the foot pad 30, the plurality of elastic bodies 340 in the liquid 350 are simultaneously pressurized, and the plurality of elastic bodies 340 are simultaneously contracted, so that the momentum of the vibration can be rapidly absorbed and converted into heat and the heat can be transferred out through the side wall of the container 310, thereby improving the shock absorption efficiency of the foot pad 30.
As shown in fig. 2, according to some embodiments of the present invention, each elastic body 340 is a hollow member, so that it can be more easily contracted, thereby enhancing a shock-absorbing effect. It will be appreciated that the elastic member 340 is a hollow member, and the hollow area can provide a compression space for the elastic member 340, which can provide better shock absorption for the foot pad 30.
As shown in fig. 2, according to some embodiments of the present invention, each elastic member 340 is formed as a sphere, so that the contact area of the elastic member 340 can be increased, and a better shock absorption effect can be achieved. Specifically, when the elastic member 340 is a sphere, the pressure from the liquid 350 may act on the surface of the elastic member 340 from various angles, increasing the force-receiving area of the elastic member 340, so that the shock-absorbing effect of the foot pad 30 may be improved. It should be noted that the stiffness of the foot pad 30 can be changed by changing the size and the structural parameters of the elastic bodies 340 and the number of the elastic bodies 340, so that the foot pad 30 can absorb the vibration of different frequencies, and the operating noise of the compressor 100 can be reduced to the maximum extent.
According to some embodiments of the present invention, each elastic member 340 is a rubber member, so that a better shock absorption effect can be achieved. Specifically, rubber, as a polymer material, has many advantages of low density, good insulation, high acid and alkali corrosion resistance, and low permeability to fluids such as air and water. When the elastic member 340 is soaked in the liquid 350 for a long time, the shock absorption effect of the elastic member 340 can be ensured, so that the service life of the foot pad 30 can be prolonged.
According to some embodiments of the invention, the liquid 350 is oil, so that pressure may be better transmitted. It will be appreciated that the oil is an incompressible fluid, and when the piston 320 applies a downward pressure to the fluid 350, the fluid 350 will instantaneously transmit the pressure to the elastomer 340 in the fluid 350, thereby improving the shock absorbing efficiency of the foot pad 30. Alternatively, the liquid 350 may be a series of liquids with poor compressibility, such as water.
According to some embodiments of the present invention, the container 310 is a steel material, thereby increasing the structural strength of the foot pad 30 and also increasing the heat dissipation from the liquid 350. It can be understood that the steel material member has good mechanical properties and workability and high structural strength, so that the structural strength of the foot pad 30 can be improved to ensure that the foot pad 30 is not easily damaged. Further, the steel material member has excellent thermal conductivity and heat resistance, when the compressor 100 operates, the elastic body 340 converts the vibration momentum of the compressor 100 into heat through self-contraction to be transferred to the side wall of the container 310, and the container 310 made of the steel material can rapidly release the heat in the container 310, so that the operating temperature of the foot pad 30 can be reduced, and the service life of the foot pad 30 can be prolonged.
As shown in fig. 1-2, according to some embodiments of the present invention, the upper end of the piston rod 330 passes through the mounting seat 40, and the portion of the piston rod 330 that passes through the mounting seat 40 is provided with an external thread that is engaged with the nut, so that the engagement between the foot pad 30 and the mounting seat 40 is simplified, and the assembly efficiency is improved. Specifically, when assembling the foot pad 30, the piston rod 330 and the piston 320 are first assembled with the container 310, and then the upper end of the piston rod 330 is inserted through a through hole (not shown) of the mounting seat 40 and screwed to the external thread of the piston rod 330 by a nut, thereby fixing the foot pad 30 to the mounting seat 40.
As shown in fig. 1 to 2, according to some embodiments of the present invention, the outer bottom wall of the container 310 is provided with a fixing space 3110 recessed upward, and the inner peripheral wall of the fixing space 3110 is provided with a mating screw, so that the assembly of the foot pad 30 with the sheet metal parts on the refrigerator can be facilitated. In a specific example of the present invention, the fixing space 3110 on the outer bottom wall of the container 310 is formed as a cylindrical hole, and the inner circumferential wall of the fixing space 3110 is provided with an internal thread, so that when the foot pad 30 is assembled with a sheet metal part on the refrigerator, the threaded post on the sheet metal part is screwed with the fixing space 3110.
As shown in fig. 1, in some embodiments of the present invention, a plurality of metal particles 50 may be filled in a cavity space formed at the bottom and the top of the compressor 100, a cavity inside the crankshaft, and the like, and when the compressor 100 operates, under the vibration generated by the compressor 100, the plurality of metal particles 50 may collide with each other in the cavity, and the metal particles 50 may also collide with the inner wall of the housing 10, so that a part of the vibration may be offset, and a shock absorption effect may be achieved.

Under the effect of vibration, a plurality of sheetmetals 20 can take place elastic deformation, and a plurality of sheetmetals 20 consume the vibration kinetic energy that compressor 100 produced through the elastic deformation of self to can play absorbing effect. By setting the natural frequencies of at least two metal sheets 20 to be different, the width of the vibration frequency absorbed by the metal sheets 20 can be increased, and the damping effect of the metal sheets 20 can be improved. Further, the vibration generated by the compressor 100 forms a downward dynamic impact load to act on the foot pads 30, the elastic body 340 in the liquid 350 is stressed and contracted, the momentum of the vibration is absorbed and converted into heat, and the heat is transmitted out through the side wall of the container 310, so that the vibration absorption effect can be achieved, the vibration generated by the compressor 100 can be prevented from being transmitted to the sheet metal parts, and the working noise of the compressor 100 can be reduced.
