Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration compressors, in particular to a low-noise refrigeration compressor. Background Art

[0002] As the core component of the refrigeration system, the refrigeration compressor converts the low-temperature and low-pressure refrigerant gas into high-temperature and high-pressure gas through mechanical compression, promotes the continuous flow of refrigerant in the refrigeration cycle, and achieves the refrigeration effect. In the current market, various types of refrigeration compressors are widely used in different fields. From the perspective of structural type, the common ones are piston type, screw type, scroll type, etc. Piston compressors are more commonly used in some small refrigeration equipment due to their high compression ratio and wide applicability.

[0003] The existing refrigeration compressor includes a compressor core and a shell. A spring is provided on the bottom of the shell cavity, and the core is installed on the spring. The spring is used to absorb the vibration of the core, thereby achieving the effect of noise reduction. However, the vibration amplitude is large and the noise reduction effect needs to be improved.

[0004] Therefore, we propose a low-noise refrigeration compressor to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to make up for the deficiencies of the prior art and to propose a low-noise refrigeration compressor, which can better absorb vibrations and has the advantages of small vibration amplitude and low noise.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A low-noise refrigeration compressor includes a compressor body, which includes a bottom shell, a top shell installed on the top of the bottom shell, a stator provided inside the bottom shell, a rotor provided inside the stator, a fan-shaped balancing block installed on the top of the rotor, an eccentric short column installed on the top surface of the fan-shaped balancing block, a piston assembly provided on the outside of the eccentric short column, the piston assembly installed on the stator, a spray elbow installed on the top surface of the eccentric short column, a universal protector provided above the stator, and an inertial damper provided on the universal protector.

[0008] Furthermore, the inertial damper includes a damping long rod, which is mounted on an eccentric short column. The damping long rod and the rotor share a central axis. The damping long rod has bending toughness, and an inertial damping ball is mounted on the top of the damping long rod.

[0009] By adopting the above technical solution, the inertial damping ball can provide damping force for the stator and rotor under the action of its own inertia. The damping force is used to reduce the horizontal swing amplitude of the stator and rotor tops, thereby greatly reducing the vibration and noise caused by component imbalance, making the compressor run more smoothly and quietly.

[0010] Furthermore, the universal protector includes a mounting bottom ring, which is fixedly connected to the inner wall of the top shell, a mounting disc is bolted on the mounting bottom ring, a conical shell is mounted on the mounting disc, a spherical hole is provided on the conical shell, a universal ball is movably installed inside the spherical hole, and the universal ball sleeve is arranged on the outside of the damping long rod, and the universal protector also includes a joint ball, which is fixedly connected to the end of the damping long rod, and the universal protector also includes a protective column, which is fixedly connected to the top surface of the eccentric short column, the protective column and the rotor share a central axis, the spray elbow is inserted into the interior of the protective column and extends from its side, a cylindrical groove is provided on the top surface of the protective column, the cylindrical groove and the protective column share a central axis, and the joint ball is movably inserted into the interior of the cylindrical groove.

[0011] By adopting the above technical solution, the damping long rod is suspended in the air and can swing, ensuring that the inertial damper can play a damping role, further making the compressor run more smoothly and quietly. The movable connection between the joint ball and the cylindrical groove replaces the fixed connection between the damping long rod and the eccentric short column, avoiding the problem of breakage of the direct fixed connection between the damping long rod and the eccentric short column due to factors such as vibration and material fatigue, and extending the service life.

[0012] Furthermore, an anti-deflection mechanism is provided above the mounting disc, and the anti-deflection mechanism includes an anti-deflection disk, which is arranged inside the top shell, an anti-deflection hole is provided on the bottom surface of the anti-deflection disk, and an anti-deflection groove is provided on the top surface of the anti-deflection disk. The anti-deflection groove is connected to the anti-deflection hole, and the anti-deflection hole and the anti-deflection groove share a central axis with the rotor. A plurality of functional column grooves are provided on the inner wall of the anti-deflection groove, and an elastic part is provided inside the functional column groove. The elastic part is in a compressed state, and a guide column is installed on the end of the elastic part. The guide column is inserted into the inside of the functional column groove, and a spherical mounting groove is provided on the end surface of the guide column. A rolling ball is movably installed inside the spherical mounting groove, and the damping long rod passes through the anti-deflection hole. The inertia damping ball is located in the anti-deflection groove, and the rolling ball and the inertia damping ball are connected by transmission.

[0013] By adopting the above technical solution, the elastic part provides thrust for the guide column, so that the guide column can provide damping force for the inertial damping ball through the rolling ball, which is used to reduce the horizontal swing amplitude of the stator and rotor top, thereby greatly reducing the vibration and noise caused by component imbalance, and once again making the compressor run more smoothly and quietly.

[0014] Furthermore, an enhancement mechanism is provided inside the anti-deflection groove, and the enhancement mechanism includes an enhancement tube, which is movably inserted into the anti-deflection hole, the inner diameter of the anti-deflection hole is larger than the outer diameter of the enhancement tube, the damping long rod is movably inserted into the interior of the enhancement tube, the inertia damping ball is slidably inserted into the interior of the enhancement tube, and the outside of the enhancement tube is fixedly sleeved with an enhancement disk, which is located inside the anti-deflection groove, and a fixed spherical groove is provided on the enhancement disk, in which a movable ball and a limiting clamp are installed, and the limiting clamp restricts the movable ball in the fixed spherical groove, and the movable ball contacts the bottom surface of the inner cavity of the anti-deflection groove, and the ball rests on the arc surface of the enhancement disk.

[0015] By adopting the above technical solution, the linkage between the efficiency-enhancing mechanism and the inertia damping ball can increase the damping force, which is used to reduce the swing amplitude of the stator and the top of the rotor in the horizontal direction, thereby greatly reducing the vibration and noise caused by the imbalance of the components, making the compressor run more smoothly and quietly. At the same time, the efficiency-enhancing mechanism can only move on the horizontal plane, avoiding the problem of the rolling ball slipping off the surface of the inertia damping ball during the flipping process of the damping long rod carrying the inertia damping ball, causing the guide column to jam the inertia damping ball, ensuring that the inertia damping ball and the elastic member can both play a damping role normally, once again making the compressor run more smoothly and quietly.

[0016] Furthermore, the guide column is made of magnetic material, the elastic part is made of material that is not affected by magnetism, and a reduction mechanism is provided inside the functional column slot, and the reduction mechanism includes a reduction column, which is movably inserted into the functional column slot, and a reduction disk is installed at the end of the reduction column, which is slidably inserted into the functional column slot, and a closed coil is provided on the outside of the reduction column, and a reduction channel is provided inside the reduction column and the reduction disk. The reduction mechanism also includes a locking disk, which is movably inserted into the functional column slot, and the locking disk and the functional column slot are threaded together, and a guide hole and a tool jack are provided on the locking disk, the elastic part is movably inserted into the reduction channel, and the guide column is movably inserted into the reduction channel and the guide hole.

[0017] By adopting the above technical solution, the guide column moves inside the amplitude reduction channel, causing the closed coil to generate an induced magnetic field. The induced magnetic field applies a damping force to the guide column. The magnitude of the damping force follows Lenz's law and is used to reduce the horizontal swing amplitude of the stator and rotor top, thereby greatly reducing the vibration and noise caused by component imbalance, and further making the compressor run more smoothly and quietly.

[0018] Furthermore, an adjustment mechanism is provided on the mounting disc, and the adjustment mechanism includes an adjusting ring, which is fixedly inserted on the mounting disc, and an annular mounting groove is provided on the inner wall of the adjusting ring, and a movable ring is movably installed inside the annular mounting groove, and an internal threaded tube is fixedly inserted inside the movable ring, and an external threaded ring is installed inside the internal threaded tube, and the internal threaded tube and the external threaded ring are threadedly matched, and the cone shell is fixedly connected to the inside of the external threaded ring, and a stop hole is provided on the external threaded ring, and a stop slide rod is slidably inserted inside the stop hole, and the top of the stop slide rod is fixedly connected to the bottom surface of the anti-deflection disk, and the adjustment mechanism also includes an adjusting slide hole, which is provided on the universal ball, and the damping long rod is slidably inserted inside the adjusting slide hole.

[0019] By adopting the above technical solution, the external threaded ring can only move up and down but cannot rotate. Through the cooperation between the external threaded ring and the internal threaded tube, people can adjust the position of the frustum shell, the spherical hole, and the universal ball relative to the damping long rod by rotating the internal threaded tube, and then adjust the degree of amplification of the vibration amplitude of the stator and rotor, so as to control the loudness of the noise, make the noise smaller, and make the compressor run quieter.

[0020] Furthermore, an adaptive mechanism is provided on the mounting disc, and the adaptive mechanism includes a right mounting vertical piece, which is fixedly connected to the mounting disc and the adjustment ring, and an induction processor is installed on the right mounting vertical piece. The adaptive mechanism also includes a left mounting vertical piece, which is fixedly connected to the mounting disc and the adjustment ring, and an actuator motor is installed on the left mounting vertical piece, and a driving bevel gear is installed on the output shaft of the actuator motor. The adaptive mechanism also includes a transmission ring gear, which is fixedly sleeved on the outside of the internal threaded tube, and the driving bevel gear is engaged with the transmission ring gear.

[0021] By adopting the above technical solution, the sensing processor can monitor the noise loudness in real time, and can control the operation of the executive motor through the sensing processor. The executive motor rotates with the internal threaded tube through the meshing action between the driving bevel gear and the transmission ring gear, thereby achieving the purpose of automatic adjustment. The sensing processor controls the executive motor to run once every period of time when the compressor is working. Each operation will make the universal ball reach the upper extreme position and the lower extreme position outside the damping rod, which is used to explore the position of the universal ball when the noise is minimum. Then, after the exploration is completed, the universal ball moves to the minimum noise position under the control of the sensing processor, thereby achieving the purpose of active noise reduction, making the noise smaller, and then making the compressor run quieter again.

[0022] Compared with the existing technology, this low-noise refrigeration compressor has the following beneficial effects:

[0023] 1. The present invention provides a long damping rod with bending toughness, so that the inertial damping ball can provide damping force for the stator and rotor under the action of its own inertia. The damping force is used to reduce the swing amplitude of the top of the stator and rotor in the horizontal direction, thereby greatly reducing the vibration and noise caused by the imbalance of the components, making the compressor run more smoothly and quietly. The long damping rod is fixed by the matching relationship between the spherical hole and the universal ball, so that the long damping rod is suspended in the air and can swing, ensuring that the inertial damper can play a damping role, further making the compressor run more smoothly and quietly. The fixed connection relationship between the long damping rod and the eccentric short column is replaced by the movable connection relationship between the joint ball and the cylindrical groove, avoiding the problem of breakage of the direct fixed connection between the long damping rod and the eccentric short column due to factors such as vibration and material fatigue, extending the service life, ensuring the normal functioning of the inertial damper, and effectively reducing the working noise.

[0024] Second, the present invention provides thrust to the guide column through an elastic member, so that the guide column can provide damping force to the inertia damping ball through the rolling ball, thereby further reducing the horizontal swing amplitude of the top of the stator and rotor. The damping force can be increased by the linkage between the synergistic mechanism and the inertia damping ball, thereby further reducing the horizontal swing amplitude of the top of the stator and rotor. At the same time, the synergistic mechanism can only move in the horizontal plane, thereby preventing the rolling ball from slipping off the surface of the inertia damping ball during the reversal of the inertia damping ball carried by the damping rod, thereby preventing the guide column from getting stuck in the inertia damping ball. This ensures that the inertia damping ball and the elastic member can both perform their damping functions normally. The guide column moves within the amplitude reduction channel, causing the closed coil to generate an induced magnetic field. The induced magnetic field applies a damping force to the guide column. The magnitude of the damping force follows Lenz's law, thereby further reducing the horizontal swing amplitude of the top of the stator and rotor. This significantly reduces the vibration and noise caused by component imbalance, further making the compressor run more smoothly and quietly, and improving the practicality of the low-noise refrigeration compressor.

[0025] Third, the present invention uses the cooperation between the anti-rotation slide bar and the anti-rotation hole to limit the external threaded ring to vertical movement but not rotation. The cooperation between the external threaded ring and the internal threaded tube allows the position of the frustum housing, the spherical hole, and the universal ball relative to the damping rod to be adjusted by rotating the internal threaded tube, thereby adjusting the degree of amplification of the stator and rotor vibration amplitudes, thereby controlling noise level and reducing noise, thereby making the compressor run quieter. The sensor processor can monitor the noise level in real time and control the operation of the actuator motor. The actuator motor rotates the internal threaded tube through the meshing action between the drive bevel gear and the transmission ring gear, achieving the purpose of automatic adjustment. The sensor processor controls the actuator motor to operate once at regular intervals while the compressor is operating. Each operation causes the universal ball to reach the upper and lower extreme positions outside the damping rod to explore the universal ball position at the minimum noise. After the exploration is completed, the universal ball moves to the minimum noise position under the control of the sensor processor, achieving the purpose of active noise reduction, reducing noise, and further achieving quieter operation of the compressor.

The zero circle corresponds to the external thread ring 705 moving upward to the extreme position, and the calibration circle corresponds to the extreme position of the external thread ring 705 moving downward. The limit number of circles is used to limit the upper and lower extreme positions of the external thread ring 705. A function can also be set inside the sensing processor 802 to automatically trigger the calibration work when the current noise loudness exceeds 20% of the noise loudness selected by the sensing processor 802 calibration. The above percentage can be set by the touch display screen to adapt to the noise generated by wear of compressor components.

[0063] Please refer to Figure 5 and Figure 6 The adaptive mechanism 8 also includes a left mounting vertical piece 803, the top of the right mounting vertical piece 801 and the left mounting vertical piece 803 are fixedly connected to the bottom surface of the anti-deflection disk 401, the left mounting vertical piece 803 is fixedly connected to the mounting disc 301 and the adjusting ring 701, and an executive motor 804 is installed on the left mounting vertical piece 803, and a driving bevel gear 805 is installed on the output shaft of the executive motor 804. The adaptive mechanism 8 also includes a transmission ring gear 806, which is fixedly sleeved on the outside of the internal threaded tube 704, and the driving bevel gear 805 is engaged with the transmission ring gear 806. The executive motor 804 rotates with the internal threaded tube 704 through the meshing action between the driving bevel gear 805 and the transmission ring gear 806, thereby achieving the purpose of automatic adjustment.

[0064] Working principle: First, the low-noise refrigeration compressor starts to operate, and then the rotor 104 rotates in a circle with the eccentric short column 106 through the sector-shaped balancing block 105, and then the eccentric short column 106 drives the piston assembly 107 to reciprocate. After that, due to the presence of the sector-shaped balancing block 105, the eccentric short column 106, and the piston assembly 107, the top of the movement is subjected to unbalanced force and produces swing vibration. Then the eccentric short column 106 brings the protective column 307 to swing synchronously. When the protective column 307 swings to the left driven by the eccentric short column 106, the protective column 307 swings to the left synchronously with the joint ball 306 through the cylindrical groove 308. Then the joint ball 306 brings the bottom end of the damping long rod 201 to swing to the left synchronously. After that, the damping long rod 201 brings the universal ball 305 to the ball joint. The surface 304 rotates internally, and then the top end of the damping rod 201 swings to the right. Then, due to the inertia of the inertia damping ball 202 and the synergistic mechanism 5, the inertia damping ball 202 and the synergistic mechanism 5 do not respond immediately, and can cause the damping rod 201 to be subjected to force. Then, the damping rod 201 bends slightly, and then the slightly bent damping rod 201 applies a damping force to the protective column 307 through the joint ball 306 and the cylindrical groove 308. Then, the protective column 307 applies a damping force to the eccentric short column 106, so that the movement is subjected to the damping force. After that, the maximum swing amplitude of the top end of the movement to the left will become smaller, and then the damping rod 201 overcomes the inertia of the inertia damping ball 202 and the synergistic mechanism 5 and drives the inertia damping ball 202 and the synergistic mechanism 5 to deviate to the right. The inertia damping ball 202 slides inside the enhancement tube 501 and will not slide out. Then the enhancement tube 501 deviates to the right inside the anti-deflection hole 402, and the enhancement disk 502 deviates to the right inside the anti-deflection groove 403. Then the enhancement disk 502 squeezes the balls 408 on its right side, and then these balls 408 push the corresponding guide posts 406 to move inside the amplitude reduction channel 604. These guide posts 406 squeeze the corresponding elastic parts 405, causing the elastic parts 405 to be elastically compressed, and the elastic potential energy is increased, thereby increasing the damping force for the enhancement mechanism 5 and the inertia damping ball 202, further reducing the maximum swing amplitude of the movement, and the remaining guide posts 406 will move outward from the inside of the amplitude reduction channel 604 under the action of the elastic force of the corresponding elastic parts 405 and carry the balls 408 all the time Pressing on the arc surface of the efficiency-enhancing disk 502, these elastic members 405 elastically stretch and their elastic potential energy decreases. At the same time, the movement of the guide post 406 into and out of the amplitude reduction channel 604 will generate an induced magnetic field in the closed coil 603 under the action of Lenz's law. A magnetic force will be generated between the induced magnetic field and the magnetic field of the guide post 406. The magnetic force is used to prevent the movement of the guide post 406. The force that prevents the guide post 406 from moving into the amplitude reduction channel 604 will be transmitted to the efficiency-enhancing mechanism 5 and the inertial damper 2 in the form of a damping force, which can once again reduce the maximum swing amplitude of the movement. Then, according to the above principle, a damping force opposite to the swing direction is provided to the movement, thereby reducing the swing vibration and thus playing a role in noise reduction. In this process,The induction processor 802 monitors and records the noise level in real time, and also records the number of revolutions of the output shaft of the execution motor 804. When the induction processor 802 reaches the set calibration time point, the induction processor 802 controls the execution motor 804 to run. Then, the execution motor 804 rotates with the internal threaded tube 704 through the meshing action between the driving bevel gear 805 and the transmission gear ring 806. Then, the external threaded ring 705 rotates relative to the internal threaded tube 704. Then, the external threaded ring 705 is threadedly engaged with the internal threaded tube 704. Under the action of the external thread ring 705, it moves upward, and then the external thread ring 705 moves upward with the universal ball 305 through the frustum shell 303 and the spherical hole 304. Then the length of the part of the damping rod 201 above the universal ball 305 is reduced, and the length of the other part is lengthened. According to the principle of leverage, it can be seen that the degree of amplification of the swing amplitude of the movement is reduced, the displacement of the inertial damping ball 202 and the efficiency enhancement mechanism 5 is reduced, the compression of the elastic member 405 is reduced, the displacement distance of the guide column 406 in the amplitude reduction channel 604 is reduced, the induced magnetic force is reduced, and finally the damping is reduced. The force becomes smaller, which can affect the swing amplitude of the movement and thus affect the noise level. After that, when the external thread ring 705 moves upward to the extreme position, the induction processor 802 controls the output shaft of the execution motor 804 to rotate in the opposite direction, and then the external thread ring 705 moves downward. Then the length of the part of the damping rod 201 above the universal ball 305 becomes longer, and the length of the other part becomes shorter. According to the principle of leverage, the degree of amplification of the swing amplitude of the movement becomes larger, the displacement of the inertial damping ball 202 and the synergistic mechanism 5 becomes larger, and the compression of the elastic member 405 becomes larger. As the pressure increases, the displacement distance of guide post 406 within reduction channel 604 increases, the induced magnetic force increases, and ultimately the damping force increases until external thread ring 705 moves downward to its extreme position. At this point, the inductive processor 802 controls actuator motor 804 to stop. The inductive processor 802 then analyzes the minimum noise and the corresponding number of rotations of the actuator motor 804 output shaft based on the recorded content. The inductive processor 802 then controls the actuator motor 804 output shaft to rotate the analyzed number of rotations, at which point the compressor noise is minimized.
