[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0040] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0041] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0042] As shown in the background technology, the compressor is the power source of the refrigeration system. Refrigeration equipment such as air conditioners and refrigerators all require a refrigeration system. During operation, the compressor will vibrate due to the rotation of its internal motor components and other reasons, and the vibration will be transmitted to the refrigeration equipment through the bottom of the compressor. Severe cases may even cause resonance of the entire machine. Therefore, in order to alleviate the vibration of the compressor and reduce the transmission of vibration energy, foot pads are generally provided at the bottom of the compressor installation position. However, in some cases, the foot pads are difficult to cope with the vibration of the compressor at different frequencies.

[0043] For example, in variable frequency compressors, the vibration of high-frequency compressors when running at high frequency is much greater than that of ordinary fixed-frequency compressors. Therefore, conventional compressor foot pads cannot dissipate the vibration energy of the compressor and reduce the transmission of compressor vibration well. For wide-band compressors, the high and low frequency span is very large, and the use of fixed hardness foot pads is difficult to cope with vibrations of different frequencies.

[0044] Based on this, see Figure 1 The present application provides a vibration reduction device 10, see Figure 2 and Figure 3 The vibration reduction device 10 is mounted at the bottom of the compressor 20 , so as to stimulate vibration reduction effects of different intensities according to the vibration condition of the compressor 20 , thereby achieving effective vibration reduction of the compressor 20 .

[0045] Specifically, see Figures 1 to 3The vibration reduction device 10 includes a vibration reduction pad 110, a magnetic induction component 120, an electromagnetic assembly 130 and a power supply structure 140. The magnetic induction component 120 and the electromagnetic assembly 130 are connected to the vibration reduction pad 110 and arranged in sequence along a set direction L. The power supply structure 140 and the electromagnetic assembly 130 are used to energize the electromagnetic assembly. The electromagnetic assembly 130 is configured to generate a magnetic flux 130a when energized so that the magnetic flux 130a passes through the magnetic induction component 120, and change the magnetic flux 130a when the vibration reduction pad 110 is deformed by force. The magnetic induction component 120 is configured to generate a force opposite to the deformation direction of the vibration reduction pad 110 when the vibration reduction pad 110 is deformed by force.

[0046] The vibration damping pad 110 can be a structure such as a rubber vibration damping pad 110, one end of which is connected to the bottom of the compressor 20 in the set direction L, and the other end is connected to the installation base to be fixed on the external structure (such as the chassis of the air conditioner), thereby providing a vibration damping effect. The vibration damping pad 110 can be an integral cylindrical shape, or formed by stacking multiple vibration damping sheets, and its specific setting form is not limited in this application. During the operation of the compressor 20, the vibration of the compressor 20 is transmitted to the vibration damping pad 110, which will cause the vibration damping pad 110 to be deformed by force. It can be understood that the vibration damping pad 110 itself has the ability to withstand terrain deformation. Within the tolerable deformation range, the vibration damping pad 110 can provide sufficient vibration damping effect for the compressor 20.

[0047] When the vibration damping pad 110 is deformed beyond the tolerable range, an auxiliary effect is provided by the combined effect of the power supply structure 140, the magnetic induction component 120 and the electromagnetic assembly 130. Specifically, the power supply structure 140 energizes the electromagnetic assembly 130, and the electromagnetic assembly 130 can generate a magnetic flux 130a after being energized and pass through the magnetic induction component 120. When the vibration damping pad 110 is deformed beyond its tolerable range, the magnetic flux 130a generated by the electromagnetic assembly 130 changes. At this time, the magnetic induction component 120 senses the deformation of the vibration damping pad 110 by sensing the change of the magnetic flux 130a, thereby generating a force in the opposite direction of the deformation of the vibration damping pad 110 when the vibration damping pad 110 is deformed, so as to resist the deformation of the vibration damping pad 110, thereby improving the vibration damping effect of the vibration damping pad 110.

[0048] Specifically, the magnetic flux 130a, also called the magnetic flux, refers to the magnetic induction intensity passing vertically through a unit area. When the vibration damping pad 110 is not subjected to stress or strain, the power supply structure 140 does not energize the electromagnetic component 130 or pass the first current, thereby not generating the magnetic flux 130a or generating the first magnetic flux. When the vibration damping pad 110 is subjected to stress and deformation, the power supply structure 140 passes the second current into the electromagnetic component 130 so that the electromagnetic component 130 generates the second magnetic flux to change the magnetic flux 130a. At this time, the magnetic flux passing through the magnetic induction component 120 switches from none to the second magnetic flux (or from the first magnetic flux to the second magnetic flux). Due to the change in the magnetic flux 130a, the magnetic induction component 120 generates a force in the opposite direction of the deformation of the vibration damping pad 110 to resist the deformation of the vibration damping pad 110 and improve the vibration damping effect of the vibration damping pad 110.

[0049] Specifically, when the magnetic induction component 120 senses a change in the magnetic flux 130a, that is, the number of magnetic flux lines passing through the magnetic induction component 120 changes, according to Lenz's law, the magnetic induction component 120 will generate an induced current. The direction of the Ampere force exerted on the induced current in the magnetic field is always at an obtuse angle to the direction of movement of the conductor, thereby hindering the movement of the conductor. Therefore, the magnetic induction component 120 will be subjected to a force opposite to the vibration direction, converting kinetic energy into electrical energy and heat energy for consumption to resist the continued vibration of the vibration damping pad 110.

[0050] In this way, the vibration reduction device 10 provided in the present application can, on the basis of the vibration reduction pad 110, assist in adding a magnetic induction component 120, an electromagnetic assembly 130 and a power supply structure 140 for electrically connecting the electromagnetic assembly 130. The position layout of the magnetic induction component 120 and the electromagnetic assembly 130 enables the magnetic flux 130a generated by the electromagnetic assembly 130 to pass through the magnetic induction component 120. When the vibration reduction pad 110 cannot achieve effective vibration reduction and produces deformation, the magnetic flux 130a of the electromagnetic assembly 130 changes, and the magnetic induction component 120 generates a force in the opposite direction of the vibration of the vibration reduction pad 110, so as to better cope with more severe vibration states under high frequencies, thereby achieving improvement in the vibration noise of the compressor 20.

[0051] It can be understood that within the tolerable range of the vibration damping pad 110, the vibration damping pad 110 will produce a certain degree of deformation. In this case, the electromagnetic component 130 and the magnetic induction component 120 do not need to assist in generating a force to satisfy the vibration damping and vibration mitigation effect on the compressor 20. Outside the tolerable range of the vibration damping pad 110, the vibration damping pad 110 cannot withstand the vibration of the compressor 20, resulting in excessive deformation of the vibration damping pad 110. At this time, the magnetic induction component 120 assists in increasing the force when the vibration damping pad 110 is deformed, thereby satisfying the vibration damping and vibration mitigation effect on the compressor 20. The greater the deformation of the vibration damping pad 110, the greater the force generated by the magnetic induction component 120.

[0052] In one embodiment, see Figures 1 to 3The power supply structure 140 is disposed at the bottom of the compressor 20 , and a setting direction L is parallel to a height direction Y of the compressor 20 . Along the setting direction L, the vibration damping pad 110 is provided with one end of a magnetic induction component 120 connected to the compressor 20 .

[0053] The vibration damping pad 110 is arranged at the bottom of the compressor 20 along the height direction Y of the compressor 20, thereby forming a certain buffer space at the bottom of the compressor 20, and the power supply structure 140 is arranged at the bottom of the compressor 20 and is located in the buffer space, so that the motor 140a and the vibration damping pad 110 are reasonably arranged without occupying other space, and the vibration damping device 10 is hidden as a whole at the bottom of the compressor 20.

[0054] Specifically, the power supply structure 140 supplies direct current to the magnetic induction component 120, and the power supply structure 140 and the electromagnetic component 130 need to be electrically connected through the wire 141. By arranging the power supply structure 140 and the vibration damping pad 110 at the bottom of the compressor 20, the power supply structure 140 and the vibration damping pad 110 are arranged relatively close to each other, which facilitates the routing of the wire 141, prevents the wire 141 from being too long, and uniformly routes the wire.

[0055] In one embodiment, see Figure 2 and Figure 3 The vibration damping device 10 includes a plurality of vibration damping pads 110 and a power supply structure 140 . Each vibration damping pad 110 is provided with an electromagnetic component 130 and a magnetic induction component 120 . The plurality of vibration damping pads 110 are arranged at intervals at the bottom of the compressor 20 , and the electromagnetic components 130 of all vibration damping pads 110 are electrically connected to the power supply structure 140 .

[0056] Specifically, a plurality of vibration-damping pads 110 can be fixed at different positions at the bottom of the compressor 20, for example, a triangular support or a four-corner support structure can be formed for the compressor 20. It can be understood that the magnitude and direction of the force generated by the magnetic induction element 120 on each vibration-damping pad 110 can be the same or different, so as to specifically reduce vibration at different positions of the compressor 20. When the vibration amplitude at a certain position of the compressor 20 is large, the force generated by the magnetic induction element 120 of the vibration-damping pad 110 at this position is large, so as to ensure the balance of the compressor 20.

[0057] Also, see Figure 5 All vibration damping pads 110 are arranged corresponding to the same power supply structure 140. At this time, the power supply structure 140 can be located at the geometric center of multiple vibration damping pads 110. At this time, the connection distance of the wire 141 between the power supply structure 140 and the electromagnetic component 130 of each vibration damping pad 110 is short and convenient.

[0058] In one embodiment, see Figure 4The vibration reduction device 10 also includes a mounting base plate 150. The power supply structure 140 and all the vibration reduction pads 110 are on one side of the mounting base plate 150. The mounting base plate 150 is provided with a mounting hole 151. Through the cooperation of the mounting hole 151 and the external structure, the vibration reduction device 10 and the compressor 20 are assembled on the external structure such as the base plate of the air conditioner.

[0059] When the electromagnetic component 130 is energized to generate the magnetic flux 130a, the magnetic flux 130a points to one side of the compressor 20 and passes through the magnetic induction component 120 arranged at one end close to the compressor 20. When the vibration damping pad 110 is deformed under force, first, the end of the vibration damping pad 110 where the magnetic induction component 120 is arranged is deformed first, so that the magnetic induction component 120 moves in position, and the magnetic flux 130a passing through it naturally changes, so that the magnetic induction component 120 generates a force to resist the deformation of the vibration damping pad 110. At the same time, the electromagnetic component 130 can continuously change the magnetic flux 130a according to the deformation degree of the vibration damping pad 110, so as to provide corresponding vibration damping and vibration mitigation effects according to different vibration conditions of the compressor 20.

[0060] Specifically, after the compressor 20 is started, the compressor 20 compresses the vibration damping pad 110, causing the vibration damping pad 110 to be skewed or deformed in multiple degrees of freedom, that is, the vibration damping pad 110 will vibrate in the vertical direction and / or in the horizontal direction, and the deformation degree of the vibration damping pad 110 can be defined by the vibration acceleration a of the vibration damping pad 110. When the vibration acceleration a of the vibration damping pad 110 meets the set conditions, it is considered that the vibration amplitude of the vibration damping pad 110 is small, that is, the deformation of the vibration damping pad 110 is within the tolerable range of the vibration damping pad 110, and at this time, the vibration damping pad 110 can well alleviate the vibration energy of the compressor 20 by itself. When the vibration acceleration a of the vibration damping pad 110 exceeds the set condition, it is considered that the vibration amplitude of the vibration damping pad 110 is large, and the vibration damping pad 110 itself cannot withstand the vibration energy transmitted by the compressor 20. At this time, after the force deformation of the vibration damping pad 110 reaches a certain degree, the magnetic induction component 120 generates a force opposite to the movement direction of the vibration damping pad 110 to resist the continued deformation of the vibration damping pad 110, thereby assisting the vibration damping pad 110 to reduce its vibration acceleration a, so as to better alleviate the vibration of the compressor 20.

[0061] In one embodiment, see Figure 1The vibration damping pad 110 is provided with an installation cavity 111, and the installation cavity 111 includes a first cavity 1111 and a second cavity 1112 arranged along a set direction L. The magnetic induction component 120 is arranged on one side of the first cavity 1111, and the side of the vibration damping pad 110 that forms a partial structure of the first cavity 1111 is connected to the compressor 20. The power supply structure 140 includes a motor 140a, and the electromagnetic component 130 includes a magnet 131 and a first coil 132. The magnet 131 is arranged in the second cavity 1112 and connected to the vibration damping pad 110, and the first coil 132 is arranged around the outer periphery of the magnet 131 and electrically connected to the motor 140a.

[0062] Specifically, the first coil 132 can be arranged around the periphery of the magnet 131 and located in the second cavity 1112, in which case the first coil 132 is located between the magnet 131 and the cavity wall of the second cavity 1112. The first coil 132 can also be arranged around the periphery of the magnet 131 and located outside the second cavity 1112, in which case the first coil 132 is arranged around the periphery of the vibration damping pad 110 away from the second cavity 1112. When the first coil 132 is energized, the magnet 131 induces a magnetic flux 130a, and the magnetic lines of force pass through the first cavity 1111 and then pass through the magnetic induction component 120.

[0063] When the vibration of the compressor 20 is transmitted to the vibration damping pad 110, causing the vibration damping pad 110 to deform, at this time, the side of the vibration damping pad 110 close to the compressor 20 is displaced, that is, the side of the vibration damping pad 110 forming the first cavity 1111 is displaced. In other words, the side of the vibration damping pad 110 provided with the magnetic induction component 120 is displaced, and the displacement of the vibration damping pad 110 drives the magnetic induction component 120 to displace at the same time. At this time, the magnetic induction component 120 forms a force that hinders the continued vibration of the vibration damping pad 110.

[0064] See also Figures 5 to 7 , Figure 5 It shows the magnetic flux 130a of the magnet 131, i.e., the magnetic force line distribution, when the vibration acceleration of the vibration damping pad 110 meets the set conditions. At this time, the vibration damping pad 110 is slightly deformed or not deformed, and the vibration damping effect is provided only by the vibration damping pad 110 itself. The magnet 131 may not generate the magnetic flux 130a at this time. Figure 6 1 shows the magnetic flux 130a of the magnet 131, i.e., the distribution of magnetic lines of force, when the vibration damping pad 110 generates horizontal vibration, thereby causing local deformation of the vibration damping pad 110. It can be understood that the horizontal direction is perpendicular to the height direction Y of the compressor 20. At this time, the magnetic induction element 120 is offset to the left and right due to the deformation of the vibration damping pad 110. The magnetic flux 130a thereof changes, and the magnetic induction element 120 forms a horizontal force, thereby hindering the horizontal movement of the vibration damping pad 110. When the vibration damping pad 110 vibrates to the right along the horizontal direction with an acceleration a, the horizontal force moves to the left along the horizontal direction.

[0065] Figure 7It is shown in the figure that when the vibration damping pad 110 generates vibration along the height direction Y of the compressor 20, thereby causing local deformation of the vibration damping pad 110, the magnetic flux 130a of the magnet 131, that is, the magnetic force line distribution, at this time, the magnetic induction component 120 moves downward due to the deformation of the vibration damping pad 110, and the magnetic flux 130a thereof changes. The magnetic induction component 120 forms a force to hinder the vertical movement of the vibration damping pad 110. When the vibration damping pad 110 is compressed in the vertical direction, the force is upward in the vertical direction to resist the vibration damping pad 110 from being further compressed.

[0066] It can be understood that the force generated by the magnetic induction component 120 is positively correlated with the number of turns of the first coil 132 and the strength of the magnet 131. If a smaller or larger force is required, the current passing through the first coil 132 can be reduced or increased through the motor 140a to reduce or increase the magnetic flux 130a, or the magnetic flux 130a can be reduced or increased by weakening or increasing the strength of the magnet 131 to alleviate the vibration of the compressor 20 in various states.

[0067] It should be noted that, in the present application, the model of the motor 140a is not limited, but it is necessary to ensure that the dimension of the vibration damping pad 110 in the height direction Y of the compressor 20 is larger than the dimension of the motor 140a in the height direction Y of the compressor 20, so that there is a buffer gap between the motor 140a and the compressor 20. When the vibration damping pad 110 is deformed by the vibration of the compressor 20 so that the compressor 20 is close to the motor 140a, the buffer gap is set so that the compressor 20 will not directly contact the motor 140a, thereby protecting the motor 140a.

[0068] In other embodiments, the power supply structure 140 may also be a rectifier plate, a circuit board, or other structures, and this application does not limit this.

[0069] In one embodiment, see Figure 1 , the maximum dimension h of the magnet 131 in the set direction L is greater than the maximum inner diameter d of the second cavity 1112, the maximum dimension of the magnet 131 in the set direction L is the maximum height of the magnet 131, and the apertures of the maximum inner diameter of the second cavity 1112 at various locations in the set direction L may be equal or unequal. When the inner diameters of the second cavity 1112 at various locations in the set direction L are equal, at this time, the inner diameter of the second cavity 1112 at any position in the set direction L is the maximum inner diameter.

[0070] It can be understood that when the magnet 131 is assembled in the first cavity 1111, the height direction of the magnet 131 is perpendicular to the inner diameter direction of the second cavity 1112. When the vibration reduction device 10 is subjected to a vibration test, if the magnet 131 is separated from the vibration reduction pad 110 and tilted, since the height h of the magnet 131 is greater than the maximum inner diameter d of the second cavity 1112, the magnet 131 cannot fall out of the vibration reduction pad 110, thereby preventing the magnet 131 from falling off during transportation.

[0071] In one embodiment, please refer to 1 again, the magnetic induction element 120 includes a second coil 121, and the second coil 121 is sleeved on the outer circumference of the partial structure of the first cavity 1111 formed by the vibration damping pad 110, and the second coil 121 and the first coil 132 are spaced apart along the set direction L.

[0072] The first coil 132 and the second coil 121 can be coils with the same number of turns and are wound at different positions of the vibration damping pad 110. Both the first coil 132 and the second coil 121 need to add enameled wire to prevent the vibration damping pad 110 from burning. The first coil 132 is used to actively connect the current of the power supply structure 140 and make the magnet 131 generate magnetic flux 130a. The second coil 121 is used to induce the change of the magnetic flux 130a of the magnet 131 and form a force to resist the deformation of the vibration damping pad 110.

[0073] At the same time, the first coil 132 and the second coil 121 are arranged at intervals and the first coil 132 is arranged around the outer circumference of the magnet 131, so that the magnetic flux 130a generated by the magnet 131 can pass through the second coil 121. The first coil 132 and the second coil 121 can be made of metal materials with good conductive properties such as copper.

[0074] In other embodiments, see Figure 8 The magnetic induction component 120 includes a conductive metal ring 122 , which is disposed in the first cavity 1111 and is in contact with the inner wall of the first cavity 1111 formed by the vibration-damping pad 110 .

[0075] The conductive metal ring 122 can be made of a metal material with good conductivity such as copper. Similarly, the first coil 132 can be made of a metal material with good conductivity such as copper. The conductive metal ring 122 is hollow inside so that the magnetic flux 130a generated by the magnet 131 can pass through its center position. The conductive metal ring 122 is arranged inside the vibration damping pad 110, which can ensure the aesthetic appearance of the vibration damping device 10.

[0076] During specific assembly, the conductive metal ring 122 can be inserted into the installation cavity 111 from one end of the second cavity 1112 and pushed inward along the set direction L until the conductive metal ring 122 is fixed in the first cavity 1111. It can be understood that at this time, the conductive metal ring 122 and the vibration damping pad 110 are interference fit.

[0077] In one embodiment, the second coil 121 or the conductive metal ring 122 may also be connected to an external battery to recover the induced current generated by the magnetic induction element 120 when it senses the magnetic flux 130a.

[0078] According to another aspect of the present application, a compressor vibration reduction system is also provided, including a detection module, a control module and a vibration reduction device 10 of any of the above embodiments, the detection module is electrically connected to the control module, the magnetic induction component 120 and the electromagnetic component 130 are electrically connected to the control module, and the electromagnetic component 130 is electrically connected to the power supply structure 140.

[0079] The detection module is used to detect the vibration acceleration of the vibration damping pad 110, the control module is used to obtain the vibration acceleration of the vibration damping pad 110 and determine whether the vibration acceleration of the vibration damping pad 110 meets the set conditions, and the control module is also used to control the power supply structure 140 to pass the vibration damping current to the electromagnetic component 130 when the vibration acceleration of the vibration damping pad 110 exceeds the set conditions, so as to change the magnetic flux 130a of the electromagnetic component 130 until the vibration acceleration of the vibration damping pad 110 meets the set conditions.

[0080] Specifically, the detection module can be an acceleration sensor, and the vibration acceleration sensor is fixed on the vibration damping pad 110. Specifically, the acceleration sensor can be set at the top position where the vibration damping pad 110 is connected to the compressor 20 to obtain the magnitude and direction of the vibration acceleration of the vibration damping pad 110.

[0081] When the detection module detects the vibration acceleration of the vibration damping pad 110, it is transmitted to the control module. After the control module obtains the vibration acceleration detected by the detection module, it compares it with the set conditions to obtain a comparison result that the vibration acceleration meets the set conditions, or the vibration acceleration is greater than the set conditions.

[0082] When the vibration acceleration meets the set conditions, it is considered that the deformation of the vibration damping pad 110 is small, the vibration acceleration is small, and there is no need to generate a force through the magnetic induction component 120 to assist in vibration reduction. When the vibration acceleration exceeds the set conditions, it is considered that the deformation of the vibration damping pad 110 is too large, and the vibration acceleration increases. At this time, it is necessary to generate a force through the magnetic induction component 120 to assist in vibration reduction until the vibration acceleration of the vibration damping pad 110 meets the set conditions.

[0083] Specifically, the control module controls the power supply structure 140 to pass a vibration-damping current into the electromagnetic component 130. When the current of the electromagnetic component 130 changes, the magnetic flux 130a generated by the electromagnetic component 130 changes, and the magnetic flux 130a passing through the magnetic induction component 120 changes. When the magnetic induction component 120 senses the change in the magnetic flux 130a, it generates a force to resist the deformation of the vibration-damping pad 110. When the compressor 20 continues to deform, that is, the vibration acceleration continues to increase, the current input into the power supply structure 140 can continue to increase to increase the force.

[0084] It can be understood that the vibration damping current is not a fixed current value. Its purpose is to generate a force to resist the deformation of the vibration damping pad 110. In actual operation, the control module can adjust the vibration damping current in real time according to the detected vibration acceleration. The greater the vibration acceleration, the greater the vibration damping current.

[0085] Then, when the magnetic induction component 120 generates a force to assist in vibration reduction until the vibration acceleration of the vibration reduction pad 110 meets the set conditions, the control module can control the power supply structure 140 to stop supplying power, or reduce the vibration reduction current to the set current, which is not limited in this application.

[0086] Regarding the specific configuration of the magnetic induction element 120 and the electromagnetic assembly 130 , please refer to the above text and will not be repeated here.

[0087] In this way, the compressor vibration reduction system of the present application uses the power supply structure 140 to control the electromagnetic component 130 of the vibration reduction device 10, thereby providing appropriate forces of different sizes according to the actual operating vibration conditions of the compressor 20, forming different vibration reduction effects, alleviating the vibration of the compressor 20 in various states, and reducing the transmission of vibration energy.

[0088] Specifically, the vibration damping pad 110 has a stable state and a deformed state. When the vibration damping pad 110 is in a stable state, the vibration acceleration of the vibration damping pad 110 meets the set conditions, and the control module power supply structure 140 passes a set current to the electromagnetic component 130. At this time, the set current can be 0, or other values ​​less than the vibration damping current. When the vibration damping pad 110 is in a deformed state, the vibration acceleration of the vibration damping pad 110 is greater than the set condition. At this time, the vibration damping current passed by the control module power supply structure 140 to the electromagnetic component 130 is greater than the set current, so that the magnetic induction component 120 generates a force opposite to the deformation direction of the vibration damping pad 110.

[0089] It can be understood that when the vibration acceleration of the vibration damping pad 110 exceeds the set conditions, different vibration accelerations correspond to different vibration damping currents. The vibration acceleration of the vibration damping pad 110 is acquired by the detection module and transmitted to the control module. The control module commands the power supply structure 140 to output different vibration damping currents according to different decelerations. At this time, the vibration damping currents corresponding to different vibration accelerations can be manually input into the control module in advance to form a preset database, or can be manually input into the control module to form a preset database and then updated later.

[0090] In one embodiment, the vibration reduction system of the compressor 20 also includes a self-update module, which is communicatively connected to the control module. The self-update module is used to memorize the vibration reduction current corresponding to different vibration accelerations when the vibration acceleration of the vibration reduction pad 110 exceeds the set conditions during the last operation of the compressor 20. The control module is used to obtain the vibration reduction current memorized by the self-update module and to control the next operation of the compressor 20, so that when the vibration acceleration of the vibration reduction pad 110 exceeds the set conditions during the next operation of the compressor 20, the power supply structure 140 can be controlled to output the corresponding vibration reduction current for different vibration accelerations.

[0091] It is understandable that the vibration damping pad 110 is a consumable. After long-term use, the vibration resistance it can provide decreases. Under different operating times of the compressor 20, even if the operating frequency of the compressor 20 is the same, the deformation degree of the vibration damping pad 110 will change. If the same vibration current is used for a long time, the vibration damping effect will deteriorate. Therefore, the present application sets a self-update module to form self-learning, so as to timely update the situation of the vibration damping pad 110 to provide a better vibration damping effect.

[0092] In addition, the self-update module is also used to memorize the set current of the vibration damping pad 110 in a stable state when the compressor 20 was last running. In one embodiment, when the compressor 20 is running, if it is running at a high frequency, it is easy for the vibration acceleration of the vibration damping pad 110 to exceed the set condition. When the compressor 20 is running, if it is running at a low frequency or in the initial startup state, the compressor 20 generates less vibration. At this time, the magnetic induction component 120 is not required to provide auxiliary force. The control module can input a current value lower than the set current (when the set current is not 0) according to the situation to reduce energy consumption.

[0093] See also Figures 9 and 10 , a diagram of the adjustment process of the vibration acceleration of the compressor 20 and the current value output by the power supply structure 140 under a specific embodiment is provided. Starting from the start of the compressor 20, the setting condition of the vibration acceleration is γ, and the setting current is α. The complete control process of the compressor vibration reduction system of the present application is as follows:

[0094] The compressor 20 starts, and the detection module starts to operate. During the startup process of the compressor 20, the vibration acceleration of the vibration damping pad 110 is less than γ, and the control module controls the power supply structure 140 not to output current or to output a current less than α;

[0095] When the detection module detects for the first time that the vibration acceleration of the vibration damping pad 110 exceeds the set condition, that is, the vibration acceleration is c, the control module retrieves the vibration damping current value β corresponding to the vibration acceleration at this time from the preset database, and controls the power supply structure 140 to output the corresponding vibration damping current β, the magnetic induction component 120 generates a force, and the detection module continues to detect. If the vibration acceleration c of the compressor 20 continues to increase during operation, the control module controls the vibration damping current β to continue to increase until the vibration acceleration γ=c, stops the input of the vibration damping current, and controls the power supply structure 140 not to output current or to output the set current α;

[0096] Moreover, during this process, the self-update module memorizes the vibration reduction current corresponding to different vibration accelerations to update the preset database, so that when the vibration reduction module detects for the second time that the vibration acceleration of the vibration reduction pad 110 exceeds the set condition, the control module retrieves the vibration reduction current value corresponding to the vibration acceleration at this time from the latest preset database.

[0097] During the operation of the compressor 20, if the vibration acceleration of the vibration damping pad 110 is less than γ, such as when the vibration acceleration is e, the control module can control the power supply structure 140 to reduce the output current, for example, output a current d less than α, thereby reducing energy consumption.

[0098] See also Fig.11 , Fig.11 A control schematic diagram of a compressor vibration reduction system is provided, wherein a detection module detects the vibration acceleration of a vibration reduction pad 110 and transmits it to a control module, and the control module controls a power supply structure 140 to output current to an electromagnetic component 130 to provide a suitable vibration reduction effect under different operating conditions of the compressor 20. At the same time, a self-update module obtains current values ​​corresponding to different vibration accelerations of the vibration reduction pad 110 and transmits them to the control module, thereby updating a preset database of the control module so as to facilitate the control module to perform the next control process.

[0099] According to the third aspect of the present application, an air conditioner is also provided, including a compressor 20 and any of the above-mentioned compressor vibration reduction systems. In this way, the present application can provide an adaptive vibration reduction strength according to the actual vibration conditions of the compressor, so that it is suitable for high-frequency compressors or wide-band compressors to alleviate the vibration of the compressor 20 in various states and reduce the transmission of vibration energy.

[0100] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
