A compressor 100 according to an embodiment of the present invention, which can be used in an air conditioner, is described below with reference to fig. 1 to 7.
As shown in fig. 1 to 7, 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 is in operation, the compressor 100 compresses the refrigerant, and after the refrigerant is compressed, 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 plays a role in supporting the compressor 100.
As shown in fig. 1, each damper assembly 20 includes a damper shell 210 and metal particles 220, the damper shell 210 being provided on an outer circumferential wall of the housing 10 and at least one damper cavity 230 being provided in the damper shell 210, at least a lower space of each damper cavity 230 being filled with the plurality of metal particles 220. Specifically, the damper housing 210 is provided on the outer circumferential wall of the housing 10 of the compressor 100, the damper housing 210 is of a hollow housing structure, a damper chamber 230 is defined in the damper housing 210, and a plurality of metal particles 220 are placed in the damper chamber 230 and can move in the damper chamber 230.
When the compressor 100 is operated, the compressor 100 generates vibration, the vibration is transmitted to the damper assembly 20 through the housing 10, the plurality of metal particles 220 in the damper cavity 230 move in the damper cavity 230 under the action of the vibration, collision and friction can be continuously performed between the metal particles 220 and the inner wall of the damper cavity 230 and between the metal particles 220 and the metal particles 220, kinetic energy of one part of the vibration is counteracted by mutual collision, kinetic energy of the other part of the vibration is converted into frictional heat energy, and the heat is discharged out of the compressor 100 through the damper shell 210, so that the damping effect can be achieved, and thus, the working noise of the compressor 100 can be reduced.
Alternatively, a plurality of damper chambers 230 may be provided in each damper housing 210, each damper chamber 230 being partitioned by a partition, and a plurality of metal particles 220 being provided in each damper chamber 230. When the compressor 100 is operated, vibration is transmitted to the damper assembly 20 through the housing 10, and collision occurs between the plurality of metal particles 220 in the plurality of damper chambers 230 in the damper assembly 20 and between the inner walls of the damper chambers 230 corresponding thereto, so that the damper efficiency of the damper assembly 20 can be improved, and the operation noise of the compressor 100 can be reduced to the maximum extent.
It should be noted that, since the plurality of metal particles 220 are disposed in the damper chamber 230, the plurality of metal particles 220 may perform irregular movement in the damper chamber 230 under the action of vibration, so that the collision and friction of the plurality of metal particles 220 may counteract the vibration of various frequencies, and may increase the damping frequency bandwidth of the damper assembly 20, thereby maximally reducing the operation noise of the compressor 100.
As shown in fig. 1 and 5-6, a plurality of foot pads 30 are respectively disposed on the mounting base 40, when the compressor 100 works, vibration generated by the compressor 100 can be transmitted to the foot pads 30 on the mounting frame, and the foot pads 30 can play a role in buffering the vibration, so that working noise of the compressor 100 can be reduced. As shown in fig. 5, each of the foot pads 30 includes a container 310, a piston 320, and a piston rod 330, the piston rod 330 is provided on the piston 320 and an upper portion of the piston rod 330 penetrates the container 310 to be fixed to the mount 40, the piston 320 is located in the container 310 and an outer circumferential wall of the piston 320 is engaged 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 under the vibration. The compression space is filled with liquid 350, and the piston 320 is in contact with the liquid surface of the liquid 350. The liquid 350 may act as a support for the piston 320 when the piston 320 is depressed. Wherein the elastic body 340 is provided in the liquid 350, and when the piston 320 applies downward pressure to the liquid 350, the elastic body 340 may contract, thereby providing a shock absorbing effect.
Specifically, when the compressor 100 is operated, the compressor 100 vibrates to form a downward dynamic impact load, and 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 downward pressure to the liquid 350. Since the liquid 350 cannot be compressed, pressure is instantaneously transferred to the elastic body 340 in the liquid 350, the elastic body 340 is stressed and contracted, the momentum of vibration is absorbed and converted into heat, and the heat is transferred out through the side wall of the container 310, thereby having a damping effect, and the vibration generated by the compressor 100 is prevented from being transferred to the sheet metal part, thereby reducing the working noise of the compressor 100.
It can be appreciated that the plurality of foot pads 30 can be disposed on the mounting base 40 of the compressor 100, when the compressor 100 vibrates, the plurality of foot pads 30 simultaneously receive downward pressure and buffer vibration, so that efficiency of buffering vibration can be improved, and working noise of the compressor 100 can be reduced better.
According to the compressor 100 of the embodiment of the present invention, by providing the damper assembly 20 and the foot pad 30, when the compressor 100 works, vibration generated by the compressor 100 can be transmitted to the damper assembly 20 through the shell 10, the plurality of metal particles 220 in the damper chamber 230 can continuously collide and rub between the metal particles 220 and the inner wall of the damper chamber 230 and between the metal particles 220 and the metal particles 220 under the action of the vibration, kinetic energy of the vibration can be counteracted by mutual collision between the metal particles 220, kinetic energy of the vibration can also be converted into frictional heat energy, and the heat is discharged out of the compressor 100 through the damper shell 210, so that the effect of damping can be achieved. Further, the vibration generated by the compressor 100 forms a downward dynamic impact load on the foot pad 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 transferred out through the side wall of the container 310, so that the vibration absorbing effect can be achieved, the vibration generated by the compressor 100 can be prevented from being transferred to the sheet metal part, and thus the working noise of the compressor 100 can be reduced.
As shown in fig. 1 to 3, according to some embodiments of the present invention, a barrier 250 is provided in the damper chamber 230, and the barrier 250 is coupled to the inner circumferential wall of the damper chamber 230, so that the damping effect of the damper assembly 20 can be improved. Specifically, for example, as shown in fig. 1, the blocking member 250 is a metal material member, and the blocking member 250 is fixed on a sidewall of the shock absorbing chamber 230 in contact with the outer circumferential wall of the housing 10 in a vulcanization manner, wherein the blocking member 250 is positioned at a middle upper portion of the shock absorbing chamber 230, the metal particles 220 are positioned at a lower portion of the blocking member 250, and a certain gap exists between the blocking member 250 and the uppermost ends of the metal particles 220. When vibration generated from the compressor 100 acts on the damper assembly 20, the metal particles 220 within the damper chamber 230 collide with each other within the damper chamber 230 and with the barrier 250. The barrier 250 exacerbates the collision between the metal particles 220 and the metal particles 220, so that the kinetic energy of vibration can be rapidly consumed, and the damping efficiency of the damper assembly 20 is improved.
In one embodiment of the present invention, the cross section of the barrier 250 is in a cross shape or a "rice" shape, so that the collision frequency between the metal particles 220 can be increased, and the shock absorbing efficiency can be improved. It is of course understood that the shape of the cross section of the barrier 250 is not limited thereto, and the barrier 250 may be formed of a metal plate in a straight shape, or the barrier 250 may be formed of a polyhedron, as long as it can function to increase the collision frequency between the metal particles 220.
As shown in fig. 1, according to some embodiments of the present invention, the filling rate of the metal particles 220 in each shock absorbing cavity 230 is 70% to 80% of the volume of the corresponding shock absorbing cavity 230, so that a good shock absorbing effect can be achieved. It is understood that when the filling rate of the metal particles 220 in the shock absorbing chamber 230 is 70% to 80%, there is a plurality of moving spaces of the metal particles 220 in the shock absorbing chamber 230. When the compressor 100 is operated, the plurality of metal particles 220 in the damper chamber 230 may collide and rub sufficiently when vibration is transmitted to the damper assembly 20, and the collision between the metal particles 220 and the metal particles 220 consumes the greatest amount of energy, thereby greatly reducing the vibration kinetic energy of the compressor 100. It will of course be appreciated that other proportions of fill rate may be selected.
In some embodiments of the present invention, each of the metal particles 220 is formed as a sphere, so that friction between the metal particles 220 and the metal particles 220 may be increased, and a shock absorbing effect may be enhanced. It can be understood that when the metal particles 220 are spheres, rolling friction is generated between the metal particles 220 and the metal particles 220, and when the damper assembly 20 is subjected to very small vibration, the metal particles 220 and the metal particles 220 can still perform mutual friction to consume kinetic energy of vibration, so that the vibration of the compressor 100 can be offset to the greatest extent, and a better damping effect is achieved. Alternatively, the constituent material of the metal particles 220 may be stainless steel, aluminum, lead, or the like. In some embodiments of the invention, each metal particle 220 has a diameter of 0.05 to 5mm. The smaller the diameter of metal particles 220, the better shock absorbing effect of shock absorbing assembly 20.
As shown in fig. 1 and 4, according to some embodiments of the present invention, an elastic material 240 is disposed on a side wall of each damper cavity 230, which is far from the housing 10, and the disposed height of the elastic material 240 is not less than the filling height of the metal particles 220, so that a better buffering effect can be achieved, and the damping effect of the damper assembly 20 is improved. Specifically, since the elastic material member 240 is provided on the side wall of the shock absorbing chamber 230 remote from the housing 10, the elastic material member 240 has a small rigidity. When the metal particles 220 collide with the inner wall of the shock absorbing cavity 230, the elastic material member 240 may lengthen the impact time of the metal particles 220 with the inner wall, thereby playing a role of buffering, so that impact noise between the metal particles 220 and the inner wall may be reduced, and also playing a role of absorbing and isolating noise, thereby maximally reducing working noise of the compressor 100. In some embodiments of the present invention, as shown in fig. 4, the elastic material member 240 extends to the top wall of the vibration damping chamber 230, so that the impact of the metal particles 220 on the inner wall of the vibration damping chamber 230 can be buffered to the maximum extent, thereby achieving a better sealing effect.
In some embodiments of the present invention, the elastic material 240 is a rubber material, so that a better buffering effect can be achieved. It will be appreciated that rubber materials have a relatively low modulus of elasticity and therefore a relatively low stiffness. When the metal particles 220 collide with the inner wall of the shock absorbing cavity 230, the rubber material can prolong the impact time between the metal material and the inner wall, so that a good buffering effect can be achieved, and a good shock absorbing effect can be achieved. Alternatively, the rubber material member may be fixed to the inner wall of the shock absorbing chamber 230 in a vulcanization manner.
As shown in fig. 7, each shock-absorbing shell 210 includes a base 2110 and an upper cover 2120, the base 2110 defining a cavity having an open top therein, the upper cover 2120 being provided on the base 2110 to cover the cavity to define the shock-absorbing cavity 230, the base 2110 being fixed to the outer circumferential wall of the housing 10, thereby making the structure of the shock-absorbing assembly 20 simpler and more convenient to operate, according to some embodiments of the present invention. Alternatively, the damper housing 210 may be fixed to the housing 10 of the compressor 100 in a vulcanization manner. In one embodiment of the present invention, the upper cover 2120 of the shock-absorbing shell 210 may be opened with respect to the base 2110 so that a user may conveniently take and put the metal particles 220. The user can increase/decrease the metal particles 220 in the shock absorbing chamber 230 according to actual demands. The user can directly open the upper cover 2120 to insert/remove the metal particles 220 into/from the shock absorbing chamber 230.
As shown in fig. 1, according to some embodiments of the present invention, a plurality of shock-absorbing members 20 are provided at both sides of a central axis of a housing 10, respectively, to be spaced apart in an up-down direction, so that noise of a plurality of frequency bands can be offset. In addition, the compressor 100 may generate vibration of various frequencies during operation, a plurality of damper assemblies 20 may be disposed in the up-down direction and the circumferential direction of the outer circumferential wall of the compressor 100 according to the frequency of the vibration, and the damper assemblies 20 of different orientations may cancel vibration of different frequencies, thereby minimizing the operation noise of the compressor 100.
It should be noted that, since the bottom of the compressor 100 is provided with the plurality of foot pads 30, the plurality of foot pads 30 can effectively buffer vibration generated by the compressor 100, and can ensure stability of the compressor 100 during operation. The damper assembly 20 on the housing 10 may not be disposed symmetrically with respect to the central axis thereof, and may be disposed at any position on the outer peripheral wall of the housing 10 according to the installation space and design requirements.
As shown in fig. 1, in some embodiments of the present invention, a plurality of metal particles 220 may be filled in a cavity space formed at the bottom and top of the compressor 100, an inner cavity of the crankshaft, etc., and when the compressor 100 is operated, the plurality of metal particles 220 may collide with each other in the cavity under the vibration generated by the compressor 100, and the metal particles 220 may collide with the inner wall of the housing 10, thereby counteracting a part of the vibration function, and thus, achieving a vibration absorbing effect.
As shown in fig. 5, according to some embodiments of the present invention, a plurality of elastic bodies 340 are provided in the liquid 350, so that a better shock absorbing effect can be achieved. Specifically, when the vibration generated by the compressor 100 forms a downward dynamic impact load on the footpad 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 quickly absorbed and converted into heat and the heat can be transferred out through the side wall of the container 310, thereby improving the shock absorbing efficiency of the footpad 30.
As shown in fig. 5, according to some embodiments of the present invention, each elastic body 340 is a hollow member, so that contraction can be more easily performed, and a shock absorbing effect can be improved. It will be appreciated that the resilient body 340 is a hollow member and the hollow region provides compression space for the resilient body 340 to provide better cushioning of the footpad 30.
As shown in fig. 5, 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 absorbing 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 stress area of the elastic member 340, and thus the shock absorbing effect of the foot pad 30 may be improved. The rigidity of the foot pad 30 may be changed by changing the size and the structural parameters of the elastic body 340 and the number of the elastic bodies 340, so that the foot pad 30 may buffer vibrations with different frequencies, thereby reducing the operation noise of the compressor 100 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 absorbing effect can be achieved. Specifically, rubber has the advantages of low density, good insulation, high acid and alkali corrosion resistance and low permeability of fluids such as air, water and the like as a polymer material. When the elastic member 340 is soaked in the liquid 350 for a long period of time, the shock absorbing effect of the elastic member 340 can be ensured, so that the service life of the footpad 30 can be prolonged.
According to some embodiments of the invention, the liquid 350 is engine oil, so that pressure may be better transferred. It will be appreciated that the oil is an incompressible fluid and that when the piston 320 applies downward pressure to the fluid 350, the fluid 350 will instantaneously transfer the pressure to the elastomer 340 in the fluid 350, thereby enhancing the cushioning efficiency of the footpad 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, which may enhance the structural strength of the footpad 30 and may also enhance the removal of heat from the liquid 350. It will be appreciated that the steel material has good mechanical properties and workability and high structural strength, so that the structural strength of the footpad 30 can be improved to ensure that the footpad 30 is not easily damaged. Further, the steel material has excellent heat conductivity and heat resistance, and when the compressor 100 is operated, the elastic body 340 converts the vibration momentum of the compressor 100 into heat through self-contraction to transfer the heat to the side wall of the container 310, and the container 310 made of steel material can rapidly release the heat in the container 310, thereby reducing the operating temperature of the foot pad 30 and prolonging the service life of the foot pad 30.
As shown in fig. 1 and 5, 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 passing through the mounting seat 40 is provided with external threads matching with nuts, so that the matching manner of the foot pad 30 and the mounting seat 40 is simpler, and the assembly efficiency is improved.
