Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to a vibration absorbing and damping device for an outdoor unit of an air conditioner and the outdoor unit of the air conditioner. Background Art

[0002] When the air conditioner is running, the compressor will vibrate at high speed, which will cause the pipeline to vibrate. If the compressor runs for a long time, it will cause problems such as cracking of the pipe group in the air conditioner outdoor unit. In addition, the vibration generated by the operation of the compressor will cause the shell of the air conditioner outdoor unit and other internal structural parts to vibrate, thereby generating noise, and will also cause the gas in the air conditioner outdoor unit to vibrate, thereby generating radiation noise, etc. The vibration will even be transmitted to the room, resulting in low-frequency transmission sound. In order to reduce the impact of compressor vibration, the air conditioner outdoor units currently on the market usually adopt passive noise reduction measures such as sound-absorbing felt to reduce the noise generated in the air conditioner outdoor unit.

[0003] However, the passive noise reduction measures adopted by the existing air-conditioning indoor unit can only reduce the noise generated in the air-conditioning outdoor unit to a certain extent, but cannot reduce the vibration of the vibration source from the source, thereby reducing the structural transmission sound and gas radiation noise caused by the vibration. In addition, there will still be problems such as pipe group cracking caused by long-term operation of the compressor. Utility Model Content

[0030] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present invention to those skilled in the art.

[0031] Figure 1 Schematic diagram of the structure of an air conditioner outdoor unit according to an embodiment of the present utility model. Figure 1 As shown, the utility model provides an air-conditioning outdoor unit 1. The air-conditioning outdoor unit 1 may generally include a housing 10, and a cavity 11 is formed in the housing 10.

[0032] At least one vibration absorbing and damping device 20 is disposed in the cavity 11. The vibration absorbing and damping device 20 is used to absorb vibration of the housing 10 to achieve active noise reduction.

[0033] like Figure 1 As shown, the vibration absorbing and damping device 20 includes an elastic component 100 and a mass block 200 that are connected and arranged. A mounting structure 14 for connecting with the elastic component 100 is also provided in the housing 10 of the air conditioner outdoor unit 1, and the elastic component 100 is connected and arranged with the housing 10 through the mounting structure 14. The mass block 200 is suspended in the cavity 11 through the elastic component 100 and moves in the cavity 11 under the action of inertia when the housing 10 vibrates. The elastic component 100 undergoes elastic deformation when the mass block 200 moves to provide elastic force for the mass block 200.

[0034] When the shell 10 of the air-conditioning outdoor unit 1 vibrates, the mass block 200 generates a displacement in the opposite direction of the vibration of the shell 10 under the action of inertia and the elastic force of the elastic component 100, so as to convert the kinetic energy of the shell 10 into the kinetic energy of the mass block 200 and the elastic potential energy of the elastic component 100, thereby achieving the effect of vibration absorption and realizing active noise reduction.

[0035] The air-conditioning outdoor unit 1 of the embodiment of the utility model eliminates the vibration generated by the operation of the compressor in the air-conditioning outdoor unit 1 to a certain extent by disposing a vibration absorbing and damping device 20 in the cavity 11 of the shell 10, thereby reducing the structural transmission sound and gas radiation noise generated by the vibration, thereby achieving active noise reduction of the noise generated in the air-conditioning outdoor unit 1 and improving the user experience.

[0036] In some embodiments, a fan (not shown in the figure), a compressor (not shown in the figure), a compressor mounting frame 12 for mounting the compressor, and a heat exchanger 13 are also disposed in the housing 10. Both the fan and the compressor can be mounted in the housing 10 via the compressor mounting frame 12.

[0037] In this embodiment, only one vibration absorbing and damping device 20 may be provided in the air conditioner outdoor unit 1. Figure 1 As shown, the vibration absorbing and damping device 20 in the air-conditioning outdoor unit 1 can be arranged between the compressor mounting frame 12 and the heat exchanger 13 to eliminate the vibration generated by the compressor, thereby reducing noise.

[0038] When the compressor mounting frame 12 and / or the heat exchanger 13 vibrates, the mass block 200 generates a displacement in the opposite direction of the vibration of the compressor mounting frame 12 and / or the heat exchanger 13 under the action of inertia and the elastic force of the elastic component 100, so as to convert the kinetic energy of the vibration of the compressor mounting frame 12 and / or the heat exchanger 13 into the kinetic energy of the mass block 200 and the elastic potential energy of the elastic component 100, thereby achieving the effect of vibration absorption and realizing active noise reduction.

[0039] In addition, since vibration is generally distributed in the up-down direction, the front-back direction, and the left-right direction. A plurality of vibration absorbing and damping devices 20 may also be provided in the air-conditioning outdoor unit 1, and at least one vibration absorbing and damping device 20 is provided between the compressor mounting frame 12 and the heat exchanger 13. In the case where there is sufficient installation space in the air-conditioning outdoor unit 1, the air-conditioning outdoor unit 1 of the utility model may also be provided with vibration absorbing and damping devices 20 at other positions to absorb the vibration of the compressor in multiple directions. For example, at least one vibration absorbing and damping device 20 is also provided in the gap formed between the side of the compressor and the casing to further eliminate the vibration generated by the compressor.

[0040] When the compressor mounting frame 12 vibrates, the mass block 200 generates a displacement in the opposite direction of the vibration of the compressor mounting frame 12 under the action of inertia and the elastic force of the elastic component 100, so as to convert the kinetic energy of the vibration of the compressor mounting frame 12 into the kinetic energy of the mass block 200 and the elastic potential energy of the elastic component 100, thereby achieving the effect of vibration absorption and realizing active noise reduction.

[0041] The air-conditioning outdoor unit 1 of the embodiment of the utility model eliminates the vibration generated by the operation of the compressor in all directions by arranging multiple vibration absorbing and damping devices 20 in the cavity 11 of the shell 10, thereby further improving the active noise reduction effect and further improving the user experience.

[0042] Combine the following Figure 2 and Figure 3 The structure of the vibration absorbing and damping device 20 of the present invention is specifically introduced.

[0043] Figure 2 Schematic diagram of the structure of a vibration absorbing and damping device according to an embodiment of the utility model. Figure 2 As shown, the vibration absorbing and damping device 20 includes an elastic component 100 and a mass block 200 which are connected and arranged.

[0044] Specifically, the vibration absorbing and damping device 20 is disposed in a cavity 11 formed inside the housing 10 of the air conditioner outdoor unit 1. The elastic component 100 is connected to the housing 10. The elastic component 100 is also connected to a mass block 200. The mass block 200 is suspended in the cavity 11 via the elastic component 100, and moves in the cavity 11 when the housing 10 vibrates to offset at least part of the vibration of the housing 10.

[0045] When the housing 10 of the air conditioner outdoor unit 1 vibrates, the mass block 200 generates a displacement in the opposite direction of the vibration of the housing 10 under the action of inertia. The elastic component 100 is deformed when the mass block 200 moves, so as to form damping of the movement of the mass block 200 by utilizing the elastic force generated by the deformation. The mass block 200 has a tendency to return to the position before the movement under the action of the elastic force of the elastic component 100, so that the mass block 200 moves repeatedly in multiple directions under the action of inertia and the elastic force of the elastic component 100, so as to convert the kinetic energy of the vibration of the housing 10 into the kinetic energy of the mass block 200 and the elastic potential energy of the elastic component 100, thereby achieving the effect of vibration absorption and realizing active noise reduction.

[0046] The vibration absorbing and damping device 20 of this embodiment is arranged in the cavity 11 formed inside the shell 10 of the air-conditioning outdoor unit 1, and is composed of an elastic component 100 and a mass block 200 which are connected and arranged, so as to realize the construction of a vibration absorbing and noise reducing structure. The elastic component 100 is connected to the shell 10, and the mass block 200 is suspended in the cavity 11 via the elastic component 100, so as to realize the transmission of the vibration generated by the shell of the air-conditioning outdoor unit 1 to the mass block 200. The mass block 200 is suspended in the cavity 11 via the elastic component 100, and when the shell 10 vibrates, it moves in the cavity 11 driven by the elastic component 100 to offset at least part of the vibration of the shell 10, thereby reducing the vibration of the shell 10 of the air-conditioning outdoor unit 1, thereby reducing the structural transmission sound and gas radiation noise generated by the vibration, and further realizing the active noise reduction of the noise generated in the air-conditioning outdoor unit 1.

[0047] In some embodiments, Figure 1 and Figure 2As shown, the elastic component 100 may include a first elastic element 110 and a second elastic element 120. The first elastic element 110 and the second elastic element 120 are elastically deformed when the mass 200 moves in the cavity 11. The first elastic element 110 is connected to the housing 10 and the mass 200 at both ends in the length direction. The middle part of the second elastic element 120 is connected to the first elastic element 110, and one end of the second elastic element 120 in the length direction is connected to the compressor mounting frame 12 in the housing 10 for mounting the compressor, so as to transmit the vibration of the compressor mounting frame 12 to the mass 200. In other words, the elastic component 100 can at least transmit the vibration of the housing 10 and the compressor mounting frame 12 to the mass 200, so as to reduce the vibration of the housing 10 and the compressor mounting frame 12 under the movement of the mass 200.

[0048] The vibration absorbing and damping device 20 of this embodiment optimizes the structure of the vibration absorbing and damping device 20 by configuring the elastic component 100 to be composed of a first elastic element 110 and a second elastic element 120 connected in the middle, wherein the first elastic element 110 is respectively connected to the housing 10 of the air-conditioning outdoor unit 1 and the mass block 200 at both ends in the length direction, and one end in the length direction of the second elastic element 120 is connected to the compressor mounting frame 12 for mounting the compressor. The air-conditioning outdoor unit 1 of this embodiment optimizes the structure of the vibration absorbing and damping device 20, reduces the vibration of the compressor mounting frame 12 caused by the vibration of the compressor in the air-conditioning outdoor unit 1, and further improves the vibration absorbing effect of the vibration absorbing and damping device 20.

[0049] In some embodiments, the first elastic member is arranged vertically, and the second elastic member is arranged horizontally, so that the mass block 200 can be stably suspended in the cavity 11. The second elastic member is arranged horizontally, which limits the swing amplitude of the mass block 200 in the horizontal direction, and further improves the stability of the mass block 200 moving in the cavity 11.

[0050] Furthermore, a mounting structure 14 for connecting with the elastic component 100 is also provided in the air-conditioning outdoor unit 1 , and the first elastic member and the second elastic member can be connected with the housing 10 or other internal components of the air-conditioning outdoor unit 1 through the mounting structure 14 .

[0051] like Figure 2 As shown, the upper end 111 of the first elastic element 110 in the length direction is connected to the top wall of the housing 10 to directly and accurately transmit the vibration of the housing 10 to the mass block 200 to reduce the vibration of the top wall of the housing 10.

[0052] In addition, a connecting piece 210 is disposed on the upper side of the mass block 200 , and the bottom end 112 of the first elastic element 110 in the length direction is connected to the connecting piece 210 of the mass block 200 to ensure the structural stability of the vibration absorbing and damping device 20 .

[0053] The vibration absorbing and damping device 20 of this embodiment utilizes a vertically arranged first elastic member to vertically suspend the mass block 200 in the cavity 11, and utilizes a horizontally arranged second elastic member to limit the swing amplitude of the mass block 200 in the horizontal direction, thereby realizing the stable suspension of the mass block 200 in the cavity 11 and allowing the mass block 200 to move freely in the up and down directions, front and back directions, and left and right directions in the cavity 11, so as to eliminate the vibration generated by the compressor in the up and down directions, front and back directions, and left and right directions, thereby improving the vibration absorbing effect, and further improving the active noise reduction effect.

[0054] In some embodiments, the mass block may be a cylindrical block. In other embodiments, the mass block may also be a square block, which is not limited in the present invention, as long as the size and shape of the mass block can satisfy the requirement of allowing the mass block to move freely in the cavity.

[0055] In addition, the first elastic element 110 and the mass block 200 may be integrally formed to reduce the difficulty of installation.

[0056] In some embodiments, a compressor, a compressor mounting frame 12 for mounting the compressor, and a heat exchanger 13 are further disposed in the housing 10 of the air-conditioning outdoor unit 1 .

[0057] In an optional implementation of the present embodiment, both ends of the second elastic element 120 in the length direction may be connected to the compressor mounting bracket 12 and the heat exchanger 13 disposed in the shell 10 respectively.

[0058] Specifically, only one vibration absorbing and damping device 20 may be provided in the air conditioner outdoor unit 1. Figure 1 As shown, the vibration absorbing and damping device 20 in the air conditioner outdoor unit 1 can be arranged between the compressor mounting frame 12 and the heat exchanger 13 to eliminate the vibration generated by the compressor, thereby reducing noise. The two ends of the second elastic element 120 in the length direction are respectively connected to the compressor mounting frame 12 and the heat exchanger 13 arranged in the housing 10.

[0059] like Figure 2 As shown, one end 121 of the second elastic element 120 in the length direction is used to connect with the compressor mounting frame 12, the other end 122 of the second elastic element 120 in the length direction is used to overlap with the heat exchanger 13, and the middle part of the second elastic element 120 in the length direction is connected to the first elastic member.

[0060] That is to say, the second elastic element 120 overlaps a beam between the compressor mounting frame 12 and the heat exchanger 13. When the mass block 200 moves in the cavity 11, the first elastic member shakes under the drive of the mass block 200, thereby driving the second elastic element 120 to undergo elastic deformation to generate free damping to absorb the vibration of the compressor and the heat exchanger 13.

[0061] When the compressor mounting frame 12 and / or the heat exchanger 13 vibrates, the mass block 200 generates a displacement in the opposite direction of the vibration of the compressor mounting frame 12 and / or the heat exchanger 13 under the action of inertia and the elastic force of the elastic component 100, so as to convert the kinetic energy of the vibration of the compressor mounting frame 12 and / or the heat exchanger 13 into the kinetic energy of the mass block 200 and the elastic potential energy of the elastic component 100, thereby achieving the effect of vibration absorption and realizing active noise reduction.

[0062] In another optional implementation of the present embodiment, both ends of the second elastic element 120 in the length direction may be connected to the compressor mounting bracket 12 and the housing 10 respectively.

[0063] Specifically, a plurality of vibration absorbing and damping devices 20 may be provided in the air conditioner outdoor unit 1. At least one of the plurality of vibration absorbing and damping devices 20 is provided between the compressor mounting frame 12 and the heat exchanger 13. The second elastic element 120 of the vibration absorbing and damping device 20 provided between the compressor mounting frame 12 and the heat exchanger 13 is connected to the compressor mounting frame 12 and the heat exchanger 13 at both ends in the length direction.

[0064] like Figure 2 As shown, one end 121 of the second elastic element 120 in the length direction is used to overlap with the compressor mounting frame 12, the other end 122 of the second elastic element 120 in the length direction is used to overlap with the shell 10, and the middle part of the second elastic element 120 in the length direction is connected to the first elastic member.

[0065] That is to say, the second elastic element 120 overlaps a beam between the compressor mounting frame 12 and the heat exchanger 13. When the mass block 200 moves in the cavity 11, the first elastic member shakes under the drive of the mass block 200, thereby driving the second elastic element 120 to undergo elastic deformation to generate free damping to absorb the vibration of the compressor and the heat exchanger 13.

[0066] Since vibration is generally distributed in the up-down direction, the front-back direction, and the left-right direction, if there is sufficient installation space in the air conditioner outdoor unit 1, some of the multiple vibration absorbing and damping devices 20 can be arranged at other positions except between the compressor mounting frame 12 and the heat exchanger 13 to absorb the vibration of the compressor in multiple directions. For example, at least one vibration absorbing and damping device 20 is further arranged in the gap formed between the side of the compressor and the casing to further eliminate the vibration generated by the compressor.

[0067] In a specific embodiment, at least one vibration absorbing and damping device 20 is disposed between the compressor mounting frame 12 and the housing 10. The second elastic element 120 of the vibration absorbing and damping device 20 disposed between the compressor mounting frame 12 and the housing 10 is connected to the compressor mounting frame 12 and the housing 10 at both ends in the length direction.

[0068] When the compressor mounting frame 12 vibrates, the mass block 200 generates a displacement in the opposite direction of the vibration of the compressor mounting frame 12 under the action of inertia and the elastic force of the elastic component 100, so as to convert the kinetic energy of the vibration of the compressor mounting frame 12 into the kinetic energy of the mass block 200 and the elastic potential energy of the elastic component 100, thereby achieving the effect of vibration absorption and realizing active noise reduction.

[0069] The air-conditioning outdoor unit 1 of the embodiment of the utility model eliminates the vibration generated by the operation of the compressor in all directions by arranging multiple vibration absorbing and damping devices 20 in the cavity 11 of the shell 10, thereby further improving the active noise reduction effect and further improving the user experience.

[0070] In addition, a plurality of vibration absorbing damping devices 20 may be provided at each vibration absorbing position to further increase the vibration absorbing effect, thereby further improving the active noise reduction effect.

[0071] In some embodiments, Figure 1 and Figure 2 As shown, the elastic element is a spring, and the middle portion of the first elastic element 110 and the middle portion of the second elastic element 120 are arranged to intersect with each other to reduce the difficulty of installation.

[0072] Figure 3 FIG. 1 is a schematic diagram of the structure of a vibration absorbing and damping device according to another embodiment of the utility model. Figure 3 As shown, in some embodiments, the second elastic element 120 includes a first spring 123, a connecting rod 124, and a second spring 125 which are sequentially connected.

[0073] The first spring 123, the connecting rod 124 and the second spring 125 are connected end to end. The first elastic element 110 includes the third spring 113, and the middle of the connecting rod 124 is connected to the middle of the third spring 113, which improves the connection stability of the first elastic element 110 and the second elastic element 120.

[0074] In some embodiments, the spring coefficient K1 of the first spring 123, the spring coefficient K2 of the second spring 125, and the spring coefficient K3 of the third spring 113 can be determined according to the vibration displacement value of the air conditioner outdoor unit captured in a preliminary experiment, so as to achieve the best vibration reduction function.

[0075] Specifically, for the first spring 123 and the second spring 125, the relationship between the spring coefficient, the deformation of the spring and the displacement is y=k*x, where x is the displacement value, y is the deformation of the first spring 123 or the second spring 125, and k represents the spring coefficient of the first spring 123 or the spring coefficient of the second spring 125.

[0076] For the third spring 113, the relationship between the spring coefficient, the deformation of the spring and the displacement is y=k*x*g, where x is the displacement value, y is the deformation of the third spring 113, k represents the spring coefficient of the third spring 113, and g is the acceleration of gravity.

[0077] It can be seen that, when the same deformation is generated, a spring with a higher spring constant can be applied to a larger displacement value. Therefore, if the vibration displacement value of the air conditioner outdoor unit captured in the preliminary experiment is obvious, a spring with a higher spring constant is used.

[0078] Specifically, the second elastic element 120 can be integrally formed to reduce the difficulty of installation.

[0079] Those skilled in the art should also understand that the vibration absorbing and damping device 20 of the present invention is particularly suitable for the air-conditioning outdoor unit 1, and can also be applied to other equipment that requires vibration absorption.
