Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of air conditioning, and in particular to a supporting device, an outdoor unit of an air conditioner and a shock absorption control method. Background Art
[0002] Motors, compressors, water pumps, etc. are widely used drive devices, which often vibrate during operation. When used in areas that require a high-quality environment, it is often necessary to damp the vibration of the drive device to avoid noise. In addition, if the vibration amplitude of the drive device is too large, it will affect the performance and life over time. For example, the compressor is a power output device used to compress the drive refrigerant in the air conditioner. It is generally installed in the outdoor unit of the air conditioner. Due to the need to compress the refrigerant, the compressor will vibrate and make noise during operation. In the prior art, compressor shock absorption is often achieved by padding with a buffer pad or a granular filler. The buffer pad is generally made of rubber and is placed between the outdoor unit chassis and the compressor foot. The elastic deformation of the rubber itself is used to buffer the vibration of the compressor. However, the rubber will age and harden after a long period of use. Not only will the elasticity of the rubber pad decrease, but it will also produce abnormal noise. In addition, the rubber pad itself has a natural vibration frequency driven by the compressor. The natural vibration frequency is relatively high and is easy to overlap with the vibration frequency of the compressor to produce resonance. The granular filler needs to be filled in the gap between the compressor and the outdoor unit chassis. The energy generated by the vibration of the compressor is transmitted through the vibration of the granular matter to reduce the vibration of the compressor. The granular filler will form a node phenomenon after a long period of use. Therefore, it is difficult to ensure the long-term effectiveness and reliability of these two vibration reduction methods in the prior art, resulting in vibration noise easily occurring in the air conditioner after a long period of use.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0049] like Figure 1 As shown, in order to achieve the above-mentioned purpose, the present invention proposes a supporting device. In a first embodiment, the supporting device includes: at least two supporting components 2, each supporting component 2 includes a cylinder body 21 and a supporting member, and the supporting member includes a supporting portion (not shown in the figure) and an adjusting portion (not shown in the figure) respectively located at both ends of the supporting member, the supporting portion is exposed to the cylinder body 21, and the adjusting portion is located in the cylinder body 21 and divides the cylinder body 21 into a first compression chamber 22 and a second compression chamber 23 (as shown in the figure). Figure 2 , 3 As shown in the figure), the first compression chamber 22 and the second compression chamber 23 are filled with compression medium (not shown in the figure), so that the support member can expand and contract under the action of the compression medium; the adjustment member is connected between the first compression chamber 22 and the second compression chamber 23 of different cylinder bodies to form a linkage adjustment structure to adjust the pressure of the compression medium in the first compression chamber 22 and the second compression chamber 23 to reach a balanced state.
[0050] The support device proposed in the present invention is used to support an object that may vibrate or tilt, such as a motor or a compressor 10 of an air conditioner. The supported object is arranged on the supporting portion of the support member and connected to the supporting portion. This connection may be a fixed connection, such as a snap connection, a threaded connection, or a screw fixation. The vibration or tilt of the supported object itself generates pressure or tension on the support member, and this pressure or tension provides power for the telescopic movement of the support member.
[0051] The support device consists of two or more, such as three (such as Figure 6 , Figure 8 as shown), four (as Fig. 9 , 12 ), etc. Each support assembly 2 includes a cylinder body 21 and a support member, the support member is arranged on the cylinder body 21, and the support member can be specifically divided into a support portion and an adjustment portion, the support portion is exposed outside the cylinder body 21, and is used to connect with the support object (such as Figure 5 The middle support part is connected to the compressor base 11), and the adjustment part is located in the cylinder body 21, dividing the cylinder body 21 into a first compression chamber 22 and a second compression chamber 23 (such as Figure 3As shown), the first compression chamber 22 and the second compression chamber 23 are both filled with compressed medium, and the adjusting member is connected between the first compression chamber 22 and the second compression chamber 23 of different cylinder bodies 21, so that the first compression chamber 22 and the second compression chamber 23 connected by the adjusting member can flow compressed medium to each other, and the adjusting member can be a connecting pipe, which is connected between the first compression chamber 22 and the second compression chamber 23 of different cylinder bodies 21, and each first compression chamber 22 is connected to at least one second compression chamber 23 so that the compressed medium in the first compression chamber 22 can flow out, and similarly, each second compression chamber 23 is also connected to at least one first compression chamber 22 so that the compressed medium in the second compression chamber 23 can flow out.
[0052] There are multiple situations for the connection between the first compression chamber 22 and the second compression chamber 23: the number of the adjusting parts is equal to the number of the supporting assemblies 2. In this case, only one adjusting part is used to connect the adjacent first compression chamber 22 and the adjacent second compression chamber 23 between the two adjacent cylinder bodies 21, that is, all the cylinder bodies 21 are connected in series to form a circulation circuit for circulating the compressed medium, so that multiple supporting assemblies 2 can achieve joint regulation; in another case, the number of the adjusting parts is greater than the number of the supporting assemblies 2 (such as Figure 6 , 8 , 9, and 12 are all in this situation. Figure 8 , 9 The dotted lines in the figure are electric wires), each first compression chamber 22 can be connected with multiple second compression chambers 23 through an adjusting member (except the second compression chamber 23 in the same cylinder body 21 as the first compression chamber 22). Similarly, the second compression chamber 23 can also be connected with multiple first compression chambers 22 through an adjusting member (except the first compression chamber 22 in the same cylinder body 21 as the second compression chamber 23). In this case, when the pressure of the medium in the first compression chamber 22 or the second compression chamber 23 changes, the compressed medium can flow out from multiple flow paths, and the adjustment is faster.
[0053] In this embodiment, a support device having three support components 2 is taken as an example. The three support components 2 are named support component No. 1 2a, support component No. 2b, and support component No. 3 2c. Support component No. 1, support component No. 2, and support component No. 3 are respectively connected to three positions at the bottom of the supported object. When the supported object vibrates or tilts and deviates from a stable state, some of the three support components 2 must be subjected to tension and some to pressure. Assuming that support component No. 1 2a is subjected to tension, and support component No. 2b and support component No. 3 2c are subjected to pressure, support component No. 1 is stretched at this time, so that the pressure in the second compression chamber 23 of support component No. 1 2a changes, causing the compressed medium in the second compression chamber 23 in the No. 1 cylinder to flow into the two first compression chambers 22 connected to the second compression chamber 23 ( The first compression chamber 22 corresponding to the second support assembly 2b and the first compression chamber 22 corresponding to the third support assembly 2c), the pressure in the two first compression chambers 22 increases, and the regulating end of the second support assembly 2b and the regulating end in the third support assembly 2c both move toward the second compression chamber 23 under the push of the pressure, so that the volume of the second compression chamber 23 decreases, the volume of the first compression chamber 22 increases, and the position of the support object fixed on the second support assembly 2b and the third support assembly 2c rises. Since the volume of the second compression chamber 23 in the second support assembly 2b and the second compression chamber 23 in the third support assembly 2c decreases, the compressed medium will further flow into the first compression chamber 22 in the first support assembly 2a, so that the compressed medium of the first compression chamber 22 in the first cylinder is replenished. In this way, the compressed medium of the entire regulating device does not change, each support assembly 2 returns to a balanced state, the vibration or tilt of the support object is adjusted, stability is guaranteed, and vibration noise of the compressor 10 can also be suppressed.
[0054] It should be noted that the above process is only a momentary equilibrium state. In fact, the vibration of the compressor 10 not only pulls up the No. 1 support assembly 2a during the above-mentioned rising process, but also presses down the No. 1 support assembly 2a in a moment. Figure 6 As shown, at this time, the flow process of the compressed medium is just the opposite: when the No. 1 support assembly 2a is subjected to downward pressure, the compressed medium in the first compression chamber 22 of the No. 1 support assembly 2a flows into the second compression chamber 23 of the No. 2 support assembly 2b and the second compression chamber 23 of the No. 3 support assembly 2c, and the compressed medium in the second compression chamber 23 of the No. 2 support assembly 2b and the first compression chamber 23 of the No. 3 support assembly 2c flows into the second compression chamber 23 of the No. 1 support assembly 2a. In this way, each support assembly returns to a balanced state, and the support rod of the No. 1 support assembly 2a cannot be pressed down, which greatly reduces the vibration amplitude of the pressure reducer 10.
[0055] It is understandable that the compressor 10 will generate operating noise in addition to the vibration noise. To further reduce the noise of the compressor 10, a muffler 6 may be installed on the compressor.
[0056] When the support device is applied to the outdoor unit of the air conditioner, the support device proposed in this embodiment can be used to support the compressor 10 of the air conditioner. The compressor 10 has three feet (not shown in the figure), and each foot is connected to a support assembly 2, so as to ensure the stability of the compressor 10 and avoid vibration. In addition, during the transportation of the air conditioner, the support device also protects the compressor 10. For example, when the compressor 10 is tilted, the support device will perform the adjustment process as described above on the compressor 10, so that the compressor 10 remains stable under the action of the tilting force, and the tilted feet return to their original positions, thereby avoiding the compressor pipeline 7 (such as Figure 4 It is understandable that the compressor 10 may also be provided with two or four feet, in which case the supporting device is provided with two or four supporting assemblies 2, and when the compressor 10 vibrates or tilts, the compressed medium flows and adjusts between the first compression chamber 22 and the second compression chamber 23 of the different cylinder bodies 21, thereby achieving the purpose of stably supporting the compressor 10.
[0057] In this embodiment, both compressible gas (such as air, inert gas) and hydraulic oil can be used as compression medium, and the compression medium filled in the first compression chamber 22 and the second compression chamber 23 is the same.
[0058] In a further embodiment, Figure 3 As shown, the support member specifically includes a support rod 24 and a piston 25. The support portion and the adjustment portion are respectively located at the two ends of the support rod 24. The piston 25 is installed on the adjustment portion and divides the corresponding cylinder 21 into a first compression chamber 22 and a second compression chamber 23. The piston 25 abuts against the inner wall of the cylinder 21, dividing the cylinder 21 into the first compression chamber 22 and the second compression chamber 23. The tension or pressure of the supported object causes the piston 25 to expand and contract in the cylinder 21. This expansion and contraction movement causes the pressure of the compressed medium in the first compression chamber 22 and the second compression chamber 23 to change, so that it can flow in the first compression chamber 22 and the second compression chamber 23 that are connected to each other, so that the entire support device returns to balance.
[0059] Based on the above first embodiment, the present invention also proposes a second embodiment, such as Fig. 9 As shown, in the second embodiment, the support device also includes: a first driving member (not shown in the figure), the power output shaft of the first driving member is connected to the support part; a pressure sensor (not shown in the figure) is arranged on the compressor 10 and / or the support part; a first controller, the first controller is electrically connected to the first driving member and the pressure sensor.
[0060] Different from the first embodiment in which the support device is powered by the vibration of the supported object to restore balance, in this embodiment, the force change of the supported object is detected by a pressure sensor, which is electrically connected to the first controller and transmits the real-time detected pressure value to the first controller. The first controller stores a preset pressure parameter. When the pressure value exceeds the pressure parameter value, the first controller sends a control signal to the first drive member. When the first drive member receives the control signal, it pulls or presses down the support part, so that the support rod 24 extends and retracts along the cylinder body 21. Different from the first embodiment in which the vibration tension or pressure is overcome by the pressure of the medium, in this embodiment, the driving force provided by the first drive member regulates the flow of the compressed medium, and the shock absorption control method is specifically proposed as follows:
[0061] S1: Obtain the pressure value detected by each pressure sensor;
[0062] S21: when the pressure value exceeds the preset range, obtaining a first driving member corresponding to the pressure sensor whose pressure value exceeds the preset range, and controlling the first driving member to drive the support rod to extend and retract, so that the pressure value detected by the pressure sensor is restored to within the preset range;
[0063] or,
[0064] S22: When the pressure value exceeds the preset range, obtain the second driving member corresponding to the pressure sensor whose pressure value exceeds the preset range, and control the second driving member to drive the piston of the accumulator to move, so that the pressure value detected by the pressure sensor is restored to the preset range.
[0065] Taking the three support assemblies 2 mentioned in the first embodiment as an example, the three support assemblies 2 are named support assembly No. 1 2a, support assembly No. 2b, and support assembly No. 3 2c, respectively. The support part of each support assembly 2 is connected to a corresponding first driving member. When it is detected that the pulling pressure on support assembly No. 1 2a is too large, the pressure sensor detects that the pressure value on support assembly No. 1 2a exceeds the preset range, and the first controller controls support assembly No. 2b and / or the second driving member corresponding to support assembly No. 3 2c to drive support assembly No. 2b and support assembly No. 3 2c to rise, so that the second compression chamber 23 in cylinder No. 2 and cylinder No. 3 flows the compressed medium to the first compression chamber 22 of cylinder No. 1, so that the first compression chamber 22 in cylinder No. 1 is quickly filled with a large amount of compressed medium, thereby suppressing the descent of support member No. 1. The pressure sensor detects the pressure on the support assembly 2 in real time. Once the first controller detects that the pressure of the No. 1 support assembly 2a has returned to the preset range, it will control the first drive member to stop applying the driving force to the No. 2 support assembly 2b and / or the No. 3 support assembly 2c, thereby achieving the pressure balance of the entire support assembly 2. In this embodiment, when the pressure sensor detects that the pressure value on the No. 1 support assembly 2a exceeds the preset range, it can further apply the driving force to the No. 1 support assembly 2a, so that the first drive member drives the No. 1 support assembly 2a to press down and overcome the support member being driven up by the supported object, thereby accelerating the speed of the support device returning to balance. The preset range here can be set to the compressor's own pressure plus or minus a certain floating value, and the floating value can be the pressure variation range allowed by the compressor vibration, such as a floating value that will not affect the working performance, or a pressure variation range that will not produce obvious noise.
[0066] Alternatively, the regulating member includes a second driving member (not shown in the figure), a second controller (not shown in the figure) and an energy storage structure connected to the connecting pipe. In this embodiment, the energy storage structure can be two or more, each energy storage structure is separately connected to a connecting pipe 31, and the energy storage structure includes a first energy storage device 32 and a second energy storage device 33, for example, Figure 8 As shown, the first accumulator 32 is connected to the first compression chamber 22 of the first support assembly 2a and the second compression chamber 23 of the third support assembly 2c through the connecting pipe, and the other accumulator is connected to the second compression chamber 23 of the first support assembly 2a and the first compression chamber 22 of the third support assembly 2c through the connecting pipe. The first accumulator 32 and the second accumulator 33 may be connected to each other through the connecting pipe 31 or not. The connection interface between the energy storage chamber and the connecting pipe is provided with a valve (not shown in the figure), and the second controller is connected to the valve to control the opening or closing of the valve. Of course, the first accumulator 32 and the second accumulator 33 may also be connected to the connecting pipe between the first support assembly 2a and the second support assembly 2b.
[0067] The second driving member is used to provide driving force for the first accumulator 32 and the second accumulator 33. The second driving member is electrically connected to the second controller and is started or closed according to the control signal of the second controller. The second controller controls the opening and closing of the first accumulator 32 and the second accumulator 33 according to the pressure value detected by the pressure sensor. For example, when the support assembly 2 is subjected to pressure and the support rod 24 is pressed down, the pressure sensor detects that the pressure value of the support assembly 2 exceeds the preset range, and the second controller controls the second driving member to open the valve of the first accumulator 32 to receive the compressed medium, and at the same time controls the second driving member to drive the piston of the second accumulator 33 to inject the compressed medium into the support assembly 2, so that the support device reaches balance. When the support rod 24 is subjected to pressure, the pressure sensor detects that the pressure value of the support assembly 2 exceeds the preset range, and the second controller controls the second driving member to drive the valve of the second accumulator 33 to open to receive the compressed medium, and drives the piston 25 of the second accumulator 33 to move, so that the compressed medium in the first accumulator 32 flows out. In this embodiment, the second controller controls the second driving member to provide power for the balance of the entire support device, thereby accelerating the speed of the support device returning to balance, so that the various feet of the compressor 10 can always be in the same horizontal plane, with a good stabilization effect. In this embodiment, the second controller is used to control the opening and closing of the first accumulator 32 and the second accumulator 33 to adjust the entire support device, which can quickly make the compressed medium quickly reach a balanced state, so that the amplitude of the support rod movement is extremely small, and the movement can be kept stable to avoid vibration.
[0068] In this embodiment, the first energy storage device 32 and the second energy storage device 33 can also be connected in another way to adjust the compressed medium: Fig. 9 As shown, the first compression chamber 22 and the second compression chamber 23 in the same cylinder body 21 are connected to the first accumulator 32 and the second accumulator 33 respectively through the connecting pipe 31. Of course, the first compression chamber 22 in the same cylinder body 21 is connected to the second compression chamber 23 connected to the second accumulator 33 in addition to the first accumulator 32, and the second compression chamber 23 in the same cylinder body 21 is connected to the first compression chamber 22 connected to the first accumulator 32 in addition to the second accumulator 33. In this embodiment, the first accumulator 32 and the second accumulator 33 work in linkage. For example, the first accumulator 32 in the same support assembly 2 is connected to the first compression chamber 22, and the second accumulator 33 is connected to the second compression chamber 23. When the support rod 24 is pressed down, the pressure in the first compression chamber 22 increases, and the compressed medium flows into the first accumulator 32, and the pressure in the second compression chamber 23 decreases, and the compressed medium flows from the second accumulator 33 into the second compression chamber 23.
[0069] Based on the above second embodiment, Fig.10 As shown, the present invention proposes a third embodiment:
[0070] The step of obtaining a first driving member corresponding to the pressure sensor whose pressure value exceeds the preset range, and controlling the first driving member to drive the support rod to move so that the pressure value detected by the pressure sensor is restored to within the preset range when the pressure value exceeds the preset range comprises:
[0071] S111: when the pressure value exceeds the preset range, obtaining a first driving member corresponding to a pressure sensor whose pressure value is greater than a maximum pressure value of the preset range, and controlling the obtained first driving member to drive the support rod to move downward;
[0072] S112: Alternatively, when the pressure value exceeds the preset range, a second driving member corresponding to a pressure sensor whose pressure value is less than a minimum pressure value of the preset range is obtained, and the obtained second driving member is controlled to drive the support rod to move upward.
[0073] The situation where the pressure value exceeds the preset range includes being less than the preset range and being greater than the preset range. Taking the three support components 2 mentioned in the first embodiment as an example:
[0074] When the No. 1 support assembly 2a is subjected to downward pressure, the pressure sensor detects that the pressure value on the No. 1 support assembly 2a is greater than the preset range, and the first controller controls the first driving member to drive the support part to move downward, and the compressed medium in the first compression chamber 22 of the No. 1 support assembly 2a flows into the second compression chamber 23 in the No. 2 support assembly 2b and the second compression chamber 23 in the No. 3 support assembly 2c, and the compressed medium in the first compression chamber 22 in the No. 2 support assembly 2b and the first compression chamber 23 in the No. 3 support assembly 2c flows into the second compression chamber 23 of the No. 1 support assembly 2a. In this way, each support assembly returns to a balanced state, and the support rod of the No. 1 support assembly 2a cannot be pressed down, which greatly reduces the vibration amplitude of the pressure reducer 10.
[0075] When the No. 1 support component 2a is subjected to tension, the No. 1 support member is stretched, and the first controller controls the first driving member to drive the support part to move upward, causing the compressed medium in the second compression chamber 23 in the No. 1 support component 2a to flow into the two first compression chambers 22 connected to the second compression chamber 23 (the first compression chamber 22 corresponding to the No. 2 support component 2b and the first compression chamber 22 corresponding to the No. 3 support component 2c). The adjusting end of the No. 2 support component 2b and the adjusting end of the No. 3 support component 2c both move toward the second compression chamber 23 under the push of the pressure, so that the volume of the second compression chamber 23 becomes smaller and the volume of the first compression chamber 22 increases. The position of the support object fixed on the No. 2 support component 2b and the No. 3 support component 2c rises. Since the volume of the second compression chamber 23 in the No. 2 support component 2b and the second compression chamber 23 in the No. 3 support component 2c becomes smaller, the compressed medium will further flow into the first compression chamber 22 in the No. 1 support component 2a, thereby the compressed medium of the first compression chamber 22 in the No. 1 cylinder is replenished. In this way, the compressed medium of the entire regulating device does not change, each supporting component 2 returns to a balanced state, and the vibration or tilt of the supported object is adjusted to ensure stability, while also suppressing the vibration noise generated by the compressor 10.
[0076] In this embodiment, due to the driving force of the first driving member, the speed of the supporting device returning to balance can be accelerated, and the compressor can be quickly adjusted to a stable state, so that the vibration amplitude of the base of the compressor 10 is reduced and the adjustment effect is good.
[0077] It can be understood that in another embodiment, a photoelectric sensor can also be used to detect the position of the base of the compressor 10 and transmit it to the first controller. The first controller controls the first driving member to provide driving force to the support assembly 2 according to the height of the base of the compressor 10. For example, when it is detected that the base of the compressor 10 connected to the No. 1 support assembly 2a is raised, the first driving member corresponding to the No. 2 support assembly 2b and the No. 3 support assembly 2c is controlled to drive the No. 2 support assembly 2b and the No. 3 support assembly 2c to rise, or the first driving member corresponding to the No. 1 support assembly 2a is controlled to drive the No. 1 support assembly 2a to press down at the same time, so that the entire support device quickly returns to balance.
[0078] In this embodiment, the pressure sensor can be arranged on the foot or support portion of the compressor 10. In an optional embodiment, a compressor chassis 11 can also be provided, the compressor chassis 11 is connected between the compressor 10 and the support portion, the compressor 10 foot is fixed on the compressor chassis 11, and the support portion is fixed on the compressor chassis 11, so that the installation of the compressor 10 is more stable. The first driving member can be a driving motor or a driving cylinder. The connection between the driving motor and the support portion can convert the rotation of the motor into linear motion through a conversion structure (not shown in the figure) to drive the support member to rise or fall. This conversion structure can be a gear rack structure or a screw structure, etc., which are not given one by one here.
[0079] Based on the above second embodiment, Fig.11 As shown, the present invention also proposes a fourth embodiment:
[0080] The step of obtaining a second driving member corresponding to the pressure sensor whose pressure value exceeds the preset range, and controlling the second driving member to drive the piston of the accumulator to move so that the pressure value detected by the pressure sensor is restored to within the preset range when the pressure value exceeds the preset range comprises:
[0081] S211: When the pressure value is greater than a preset range, controlling the energy storage device to open to receive the compressed medium;
[0082] S212: Acquire a second driving element corresponding to the pressure sensor whose pressure value is less than the minimum pressure value of the preset range;
[0083] S213: Control the second driving assembly connected to the energy accumulator to drive the piston of the energy accumulator, so that the pressure value detected by the pressure sensor is restored to within the preset range.
[0084] The second controller controls the opening and closing of the first accumulator 32 and the second accumulator 33 according to the pressure value detected by the pressure sensor. For example, when the support assembly 2 is subjected to pressure and the support rod 24 is pressed down, the pressure sensor detects that the pressure value of the support assembly 2 is greater than the preset range, and the second controller controls the second driver to open the valve of the first accumulator 32 to receive the compressed medium from the first compression chamber 22, and controls the second driver to drive the piston of the second accumulator 33 to inject the compressed medium into the second compression chamber 23 of the support assembly 2, so that the support device reaches balance. When the support rod 24 is subjected to pressure, the pressure sensor detects that the pressure value of the support assembly 2 is less than the preset range, and the second controller controls the second driver to drive the valve of the second accumulator 33 to open to receive the compressed medium from the second compression chamber 23, and drives the piston 25 of the second accumulator 33 to move, so that the first accumulator 32 injects the compressed medium into the first compression chamber 23. In this embodiment, the second controller controls the second driver to provide power for the balance of the entire support device, thereby accelerating the speed of the support device returning to balance, so that each foot of the compressor 10 can always be in the same horizontal plane, with a good stabilization effect. In this embodiment, the second controller is used to control the opening and closing of the first energy accumulator 32 and the second energy accumulator 33 to adjust the entire support device, which can quickly make the compressed medium reach a balanced state, so that the movement amplitude of the support rod is extremely small, and the movement can be kept stable to avoid vibration.
[0085] The first energy accumulator 32 and the second energy accumulator 33 play the role of storing or releasing the compressed medium. When there is no first controller and second controller, the support device relies on the tension or pressure generated by the vibration or tilt of the supported object to restore balance. For example, the support device has four support components 2: Figure 8 As shown, when the No. 1 support assembly 2a is subjected to pressure, the first compression chamber 22 of the No. 1 support assembly 2a is pressed down by the support member, causing the pressure of the compressed medium to increase and flow into the first accumulator 32, and the No. 2 support assembly 2b and the No. 3 support assembly 2c are subjected to tension, and the pressure in the two first compression chambers 22 corresponding to the No. 2 support assembly 2b and the No. 3 support assembly 2c is reduced, and the compressed medium in the first accumulator 32 flows into the first compression chamber 22 of the No. 3 support assembly 2c and the second compression chamber 23 of the No. 2 support assembly 2c where the pressure is reduced, thereby returning the first compression chamber 22 of the entire support device to balance; the compressed medium in the second accumulator 33 flows in the same direction as the No. 1 support assembly 2c. The compressed medium in the first accumulator flows in the opposite direction. When the first compression chamber 22 of the first support assembly 2a is pressed down by the support member, causing the pressure of the compressed medium to increase and flow into the first accumulator 32, the pressure in the second compression chamber 23 of the first support assembly 2a decreases. At this time, the second accumulator 33 injects compressed medium into the second compression chamber 23 of the first support assembly 2a, and the second compression chamber 23 of the second support assembly 2c flows compressed medium into the second compression chamber 23 of the first support assembly 2a, and the second compression chamber 23 corresponding to the third support assembly 2c injects compressed medium into the second accumulator 33, so that the second compression chamber 23 of the entire support device returns to balance. In this embodiment, the support device relies on the tension or pressure generated by the vibration or tilt of the support object to restore balance. The first accumulator 32 and the second accumulator 33 are equivalent to a device for storing the vibration energy of the support object for the entire support device, temporarily storing the energy of the tension or pressure generated by the vibration or tilt of the support object and then gradually releasing it to each support assembly 2. In this embodiment, when the support assembly 2 is two, three or four ( Fig. 9 , 12 (The figure shows a situation where four supporting devices are connected to each other) In the above case, the flow mode of the compressed medium between the first energy accumulator 32 and the second energy accumulator 33 and each supporting assembly 2 is the same as described above, and will not be repeated here.
[0086] In this embodiment, the first energy accumulator 32 and the second energy accumulator 33 can have the same structure as the support assembly 2. The cavities inside the first energy accumulator 32 and the second energy accumulator 33 are divided into a first energy storage chamber (not shown in the figure) and a second energy storage chamber (not shown in the figure) by a piston (not shown in the figure), and a plunger rod (not shown in the figure) is fixed on the piston.
[0087] The regulating member also includes an electronic regulating valve (not shown in the figure), which is connected to the connecting pipe and is electrically connected to the second controller. The opening of the electronic regulating valve is controlled by the second controller, so that the flow rate of the compressed medium entering or flowing out of the first accumulator 32 and the second accumulator 33 can be adjusted. It can be understood that in a specific implementation, the opening of the electronic regulating valve can be adjusted according to the pressure detected by the pressure sensor, such as adjusting the electronic regulating valve to a large opening when the detected pressure value is large, and adjusting the electronic regulating valve to a small opening when the detected pressure value is small.
[0088] The supporting device further comprises a connecting plate 26 , which is fixed on the supporting portion and has a movable gap 27 between the connecting plate 26 and the cylinder body 21 .
[0089] The connecting plate 26 is fixed on the support part and moves with the support rod 24. The connecting plate 26 provides a mounting base for fixing the supported object. The supported object is fixed on the connecting plate 26, thereby forming a fixed connection with the support rod 24. When applied to the compressor 10 of the air conditioner, the connecting plate 26 can also be fixedly connected to the compressor chassis 11, so that the compressor chassis 11 can move with the movement of the support rod 24. At this time, the compressor 10 is installed on the compressor chassis 11. There is a movable gap 27 between the connecting plate 26 and the cylinder body 21, thereby providing space for the movement of the connecting plate 26 to avoid interference between the connecting plate 26 and the cylinder body 21 during the movement. In this embodiment, the overall height of each support assembly 2 is between 30mm and 50mm. Within this height range, a certain gap can be ensured between the compressor chassis 11 and the outdoor unit to prevent the vibration of the compressor chassis 11 from being transmitted to the outdoor unit chassis 5. The thickness of the connecting plate 26 is between 3mm and 6mm. This thickness range of the connecting plate 26 allows sufficient movable gap 27 to be left between the connecting plate 26 and the cylinder body 21. The height range of the cylinder body 21 is between 10mm and 20mm, and the diameter range is between 20mm and 35mm. The height range of the piston 25 is between 3mm and 6mm, and the diameter range is between 20mm and 35mm. The piston 25 abuts against the inner wall of the cylinder body 21 to separate the cylinder body 21 into a first compression chamber 22 and a second compression chamber 23. The diameter range of the connecting pipe is between 2mm and 5mm.
[0090] Compared with the shock absorbing method using rubber pads in the prior art, the natural frequency of the support device itself proposed by the present invention is smaller, and the overlapping area with the working frequency (10Hz-110Hz) of the compressor 10 is smaller, so the probability of resonance is greatly reduced. The following table shows the natural frequencies of the support device and the rubber pad in six degrees of freedom, respectively. The first-order X translation, second-order Y translation, third-order rotation around Z, fourth-order Z translation, fifth-order rotation around X, and sixth-order rotation around Y in the table represent the degrees of freedom in six directions:
[0091] Table 1 Natural frequencies of the support device and rubber pad in six degrees of freedom
[0092] Vibration reduction system First-order X translation Second-order Y translation Third-order rotation around Z Fourth-order Z translation Fifth-order rotation around X Sixth-order rotation about y Support device 5.24 6.12 9.54 12.74 17.12 18.44 Rubber pad 8.04 8.06 18.04 24.66 28.5 29.49
[0093] like Fig.13 The natural frequencies of the support device and the rubber pad corresponding to each degree of freedom are shown in Table 1 and Fig.10 It can be seen from the data in that the natural frequency of the support device itself is much smaller than the natural frequency of the rubber pad, so the probability of resonance with the compressor 10 is smaller, which can reduce the probability of greater vibration caused by the resonance of the compressor 10 and achieve better shock absorption effect.
[0094] The present invention further provides an outdoor unit of an air conditioner, which includes a compressor 10 and the above-mentioned supporting device, wherein a supporting portion of the supporting device is connected to the compressor 10 .
[0095] The compressor 10 has three feet, each of which is connected to a support assembly 2. Since the support device will eventually return to a balanced state when subjected to the tension or pressure of the compressor 10, the vibration or tilt of the compressor 10 is dynamically adjusted, ensuring stability, and further suppressing the vibration and noise generated by the compressor 10. In addition, during the transportation of the air conditioner, the support device also protects the compressor 10. For example, when the compressor 10 is tilted, the support device will perform the adjustment process as described above on the compressor 10, so that the compressor 10 remains stable under the action of the tilting force, avoiding the pipeline from being pulled and damaged. It can be understood that the compressor 10 can also be provided with two or four feet. In this case, the support device is correspondingly provided with two or three support assemblies 2. When the compressor 10 vibrates or tilts, the compressed medium flows and adjusts between the first compression chamber 22 and the second compression chamber 23 of the different cylinder bodies 21, thereby achieving the purpose of stably supporting the compressor 10.
[0096] In a further embodiment, the outdoor unit of the air conditioner also includes a compressor chassis 11, the compressor chassis 11 is fixedly connected to the support part, the compressor 10 is installed on the compressor chassis 11, and the pressure sensor of the supporting device is arranged on any one of the compressor 10, the supporting part of the supporting device and the compressor chassis 11.
[0097] The compressor chassis 11 is connected between the compressor 10 and the support part, the compressor 10 foot is fixed on the compressor chassis 11, and the support part is fixed on the compressor chassis 11, so that the installation of the compressor 10 is more stable. In this way, the pressure sensor can also be arranged on the compressor chassis 11. In addition, the pressure sensor can also be arranged on the compressor 10 (such as the foot of the compressor 10) or the support part of the support device.
[0098] The outdoor unit chassis 5 provides an installation base for the entire outdoor unit, and the cylinder 21 of the supporting device is fixed on the outdoor unit chassis 5. The outdoor unit also includes a main control board, and the controller is integrated on the main control board, thereby saving assembly space and integrating control devices into one, which is convenient for assembly and wiring.
