Description

Technical Field

[0001] This utility model belongs to the field of air conditioning equipment technology, and in particular relates to an outdoor unit of an air conditioner. Background Technology

[0002] The compressor in the outdoor unit of an air conditioner is connected to the base plate of the outer casing by mounting feet at the bottom through vibration damping blocks. When running, the vibration of the compressor is transmitted to the sheet metal parts such as the outer casing through the bolts on the mounting feet. When the sheet metal parts vibrate, they radiate noise outward, affecting the user's comfort and mental health.

[0003] A common noise reduction measure is to install a soundproof cover outside the compressor. By increasing the sound insulation of the cover, the transmission of compressor noise can be reduced. However, this sound insulation method is not very effective for low-frequency noise caused by vibration. This is because low-frequency noise has a longer wavelength, is prone to diffraction, has strong penetrating power, and is difficult to isolate. It can only partially reduce the outward transmission of vibration noise, but cannot fundamentally reduce the generation and transmission of vibration. Utility Model Content

[0004] The purpose of this utility model is to provide an outdoor unit for an air conditioner to solve the problem in the prior art where the vibration of the compressor during operation generates noise, and sound insulation and noise reduction structures such as soundproof covers can only reduce part of the noise transmission, but cannot reduce the vibration of the compressor at the source.

[0005] To achieve the above-mentioned objectives, the present invention employs the following technical solution:

[0020] The first buffer protrusion is used to prevent the first fastener and the mounting feet from directly contacting each other, and to reduce the transmission of vibration generated by the compressor to the support through the first fastener.

[0021] In some embodiments of this application, a second support assembly is provided between the support member and the base plate.

[0062] In this application, the air conditioner performs a refrigeration cycle by using a compressor, condenser, expansion valve, and evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0063] Low-temperature, low-pressure refrigerant enters the compressor, which compresses it into a high-temperature, high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0064] The expansion valve expands the high-temperature, high-pressure liquid refrigerant that condenses in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the expanded refrigerant in the expansion valve and returns the low-temperature, low-pressure refrigerant gas to the compressor. The evaporator achieves its cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner regulates the temperature of the indoor space.

[0065] The outdoor unit of an air conditioner refers to the part of the refrigeration cycle that includes the compressor and the outdoor heat exchanger. The indoor unit of an air conditioner includes the indoor heat exchanger, and an expansion valve can be provided in either the indoor or outdoor unit.

[0066] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner functions as a heater in heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner functions as a cooler in cooling mode.

[0067] refer to Figure 1 , Figure 2 This application proposes an outdoor unit for an air conditioner, which includes an outer casing, a compressor 200, a heat exchanger, and a piping assembly 100 connecting the compressor 200 and the heat exchanger.

[0068] The outer casing includes an installation cavity formed by a top plate, a bottom plate 400, and side plates, and the heat exchanger and compressor 200 are disposed in the installation cavity.

[0069] Combination Figure 4 The compressor 200 is provided with mounting feet 210 at the bottom. The mounting feet 210 are connected to the housing through the support member 300. Specifically, the mounting feet 210 are supported on the base plate 400 through the support member 300.

[0070] refer to Figure 6 , Figure 7 The support member 300 has an installation port 301, and a vibration-absorbing member 330 is provided inside the installation port 301.

[0071] The vibration damping member 330 includes a mass part 331 and an elastic part 332. The mass part 331 is connected to the mounting port 301 through the elastic part 332.

[0072] The size of the mounting port 301 is larger than that of the mass part 331, and the elastic part 332 is connected between the inner wall of the mounting port 301 and the mass part 331.

[0073] The mounting port 301 is located in the middle of the support member 300, and the center of gravity of the mass part 331 coincides with the center of the mounting port 301 so as to balance the force on the support member 300.

[0074] Among them, a lower support gap is formed between the support member 300 and the base plate 400, and an upper support gap is formed between the support member 300 and the compressor 200.

[0075] Under the action of the elastic part 332, the mass part 331 is configured to vibrate left and right within the mounting port 301 or vibrate up and down between the upper support gap and the lower support gap.

[0076] In some embodiments of this application, in order to make the center of gravity of the mass part 331 coincide with the center of the mounting port 301, the cross-sectional shape of the mass part 331 along the horizontal direction is designed to be a regular polygon or a circle.

[0077] For example, but not limited to, the cross-sectional shape of the mass part 331 along the horizontal direction is an equilateral triangle, a square, etc.

[0078] In some embodiments of this application, the elastic part 332 includes two or more springs evenly arranged along the periphery of the mass part 331, one end of the spring is connected to the mass part 331, and the other end of the spring is connected to the support member 300.

[0079] All springs are of the same length so that the force on the periphery of the mass part 331 is uniform.

[0080] When the compressor 200 vibrates, the vibration is transmitted to the mass part 331. The mass part 331 can vibrate up and down and back and forth, so that the spring card deforms and absorbs the vibration energy of the compressor 200.

[0081] Specifically, the support member 300 is a support plate structure. In order to improve the structural strength of the support member 300 and provide stable support for the compressor 200, the support member 300 is designed with a bent portion 302 extending towards the compressor 200 on its periphery.

[0082] Alternatively, the bent portion 302 can extend towards the base plate 400. The bent portion 302 is continuously distributed along the circumference of the support member 300 without any breaks in the middle, which can greatly improve the strength of the support member 300.

[0083] In other embodiments, a forming element may be provided on the support member 300 along the periphery of the mounting opening 301 to further improve the structural strength of the support member 300 itself.

[0084] When the compressor 200 vibrates, the vibration is transmitted to the mass part 331 through the support member 300. The mass part 331 can vibrate up and down and back and forth under the action of the elastic part 332. The elastic part 332 is used to absorb the vibration energy of the compressor 200 with the vibration of the mass part 331, reduce the outward transmission of vibration, fundamentally reduce the generation of noise, and help improve the low-frequency noise caused by the vibration of the compressor 200.

[0085] refer to Figures 3-5 In some embodiments of this application, a buffer structure is provided between the compressor 200 and the support member 300, and / or between the support member 300 and the base plate 400, to reduce the transmission of vibration generated by the operation of the compressor 200 to the base plate 400.

[0086] A first support assembly 310 is provided between the compressor 200 and the support member 300, and a second support assembly 320 is provided between the support member 300 and the base plate 400.

[0087] The first support component 310 includes a first buffer leg 311 and a first fastener 312. The first buffer leg 311 is made of rubber material and plays a role in buffering and vibration reduction.

[0088] A first fixing part is formed on the mounting foot 210, and a second fixing part 303 is provided at the corresponding position of the support member 300. A first buffer foot 311 is disposed between the first fixing part and the second fixing part 303. A first fastener 312 passes through the corresponding second fixing part 303, the first buffer foot 311 and the first fixing part to connect the mounting foot 210 to the support member 300.

[0089] Specifically, the mounting feet 210 on the compressor 200 are arranged at equal angles around the compressor 200, and there are at least three of them. The number of the second fixing parts 303 on the support 300 corresponds one-to-one with the number of the mounting feet 210, and the centroid of the polygon formed by the lines connecting each second fixing part 303 coincides with the center of the mounting opening 301.

[0090] A through connection channel is formed on the first buffer support leg 311, and the first fastener 312 passes through the first fixing hole, the second fixing hole and the connecting channel mounting foot 210 and is fixed on the support member 300.

[0091] refer to Figure 8 The first fixing part is a through fixing hole structure formed on the mounting foot 210, and the second fixing part 303 is a through fixing hole structure formed on the support member 300. A first buffer protrusion 3111 is formed on the first buffer foot 311, and the first buffer protrusion 3111 is inserted into the first fixing part from bottom to top.

[0092] The design of the first buffer protrusion 3111 on the first buffer support leg 311 can isolate the mounting base 210 and the first fastener 312, reducing the vibration transmitted downward to the support member 300 through the first fastener 312.

[0093] Similarly, the second support component 320 includes a second buffer leg 321 and a second fastener 322. The second buffer leg 321 is made of liquid rubber material and plays a buffering and vibration reduction role between the support component 300 and the base plate 400.

[0094] A third fixing part 304 is formed on the support member 300, and a fourth fixing part 410 is provided at the corresponding position on the base plate 400. The second buffer support leg 321 is disposed between the third fixing part 304 and the fourth fixing part 410.

[0095] The number of third fixing parts 304 is at least three, and the centroid of the polygon formed by the lines connecting the third fixing parts 304 coincides with the center of the mounting port 301.

[0096] The second fastener 322 passes through the corresponding fourth fixing part 410, the second buffer leg 321 and the third fixing part 304 to connect the support member 300 to the base plate 400.

[0097] The third fixing part 304 is a through fixing hole structure formed on the mounting foot 210, and the fourth fixing part 410 is a through fixing hole structure formed on the base plate 400. The second buffer support foot 321 has a second buffer protrusion, which is inserted into the third fixing part 304 from bottom to top.

[0098] The design of the second buffer protrusion on the second buffer leg 321 can isolate the support 300 and the second fastener 322, reducing the vibration transmitted downward to the base plate 400 through the second fastener 322.

[0099] Both the first fastener 312 and the second fastener 322 include a bolt portion and a nut portion, the end of which is formed with a threaded section, and the nut portion is threadedly connected to the threaded section.

[0100] The first support component 310 and the second support component 320 help reduce the vibration transmission of the compressor 200 and further reduce noise.

[0101] The outdoor unit of the air conditioner involved in this application, in addition to supporting the compressor 200, can also absorb the vibration generated during the operation of the compressor 200, thereby reducing the outward transmission of vibration and reducing the formation of noise from the source. The low-frequency humming sound caused by vibration is significantly improved, with an improvement of more than 4dB(A).

[0102] In addition, the structural strength is significantly improved due to the bends 302 on the periphery of the support component 300. The optimized design of the position where the compressor 200's gravity acts and the support position of the support component 300 ensures a stable center of gravity, preventing overturning due to bumps during transportation. Compared to traditional structures, this compressor 200's vibration-damping and noise-reducing design occupies less space, is easier to install, and is suitable for mass production.

[0103] refer to Figures 9-11 The compressor 200 is connected to a piping assembly 100 at its input or output end. The piping assembly 100 includes a first piping unit 110 and a second piping unit 120.

[0104] The first piping unit 110 includes a first arc-shaped pipe section 111, and the second piping unit 120 includes a second arc-shaped pipe section 121. The first piping unit 110 and the second piping unit 120 are connected, and the first arc-shaped pipe section 111 and the second arc-shaped pipe section 121 are arranged in a ring.

[0105] The other ends of the first piping unit 110 and the second piping unit 120 are respectively connected to other pipe fittings, and are connected to the input or output end of the compressor 200 and working components such as heat exchangers through other pipe fittings.

[0106] The ring formed by the first arc-shaped pipe segment 111 and the second arc-shaped pipe segment 121 is a three-dimensional ring. One end of the first arc-shaped pipe segment 111 and the second arc-shaped pipe segment 121 are located on the same straight line, and the other end is arranged in a staggered manner. The axes are located on different straight lines, and the piping assembly 100 itself does not have spatial contact or interference.

[0107] refer to Figure 12 , Figure 13 Specifically, the first piping unit 110 is connected to the second piping unit 120 at one end with a mating pipe section 112, and the second piping unit 120 is connected to the first piping unit 110 at the other end with a plug pipe section 122. The inner diameter of the mating pipe section 112 is matched with the outer diameter of the plug pipe section 122, and the plug pipe section 122 is inserted into the mating pipe section 112.

[0108] The mating pipe section 112 is specifically a straight pipe section formed by the first piping unit 110 through a pipe expansion process to increase its corresponding inner diameter, so that the insertion pipe section 122 is connected in the mating pipe section 112, thereby realizing the initial connection between the first piping unit 110 and the second piping unit 120.

[0109] Specifically, after the insertion pipe section 122 is connected to the mating pipe section 112, the insertion pipe section 122 and the mating pipe section 112 need to be further connected and fixed by welding.

[0110] A first straight pipe section 113 is also provided between the mating pipe section 112 and the first arc-shaped pipe section 111 to realize the transition between the mating pipe section 112 and the first arc-shaped pipe section 111, so as to facilitate the hole expansion process of the mating pipe section 112.

[0111] The outer diameter of the first straight pipe section 113 is equal to the outer diameter of the first arc-shaped pipe section 111. A transition section 101 is formed between the first straight pipe section 113 and the mating pipe section 112. The transition section 101 facilitates the transition between the first straight pipe section 113 and the mating pipe section 112, avoiding problems such as stress concentration.

[0112] The first arc-shaped pipe section 111 is provided with a second straight pipe section 114 at one end away from the first straight pipe section 113, and the other end of the second straight pipe section 114 is connected to the third straight pipe section 116 through the first turning pipe section 115.

[0113] The second straight pipe section 114 and the third straight pipe section 116 are located on both sides of the first turning pipe section 115, which facilitates the clamping and positioning of the first piping assembly 100 when processing the first turning pipe section 115.

[0114] The second arc-shaped pipe section 121 is also provided with a fourth straight pipe section 123 at one end away from the insertion pipe section 122. The other end of the fourth straight pipe section 123 is connected to the fifth straight pipe section 125 through the second turning pipe section 124.

[0115] Similarly, the fourth straight pipe section 123 and the fifth straight pipe section 125 are located at both ends of the second bend pipe section 124, which facilitates the clamping and positioning of the second piping assembly 100 when processing the second bend pipe section 124.

[0116] The first bend pipe section 115 and the second bend pipe section 124 are bent in opposite directions so that the center line of the third straight pipe section 116 and the center line of the fifth straight pipe section 125 are on the same straight line.

[0117] For example, but not limited to, in Figure 10 In the direction shown, the first arc-shaped pipe segment 111 in the first piping assembly 100 is deflected outward relative to the plane of the paper, and correspondingly, the first bend pipe segment 115 is bent inward relative to the plane of the paper. The second arc-shaped pipe segment 121 in the second piping assembly 100 is deflected inward relative to the plane of the paper, and the second bend pipe segment 124 is bent outward relative to the plane of the paper, so that the center line of the third straight pipe segment 116 and the center line of the fifth straight pipe segment 125 are on the same straight line.

[0118] Specifically, for ease of processing, both the first and second bent pipe sections consist of two opposing arc segments, specifically, a first arc segment 102 and a second arc segment 103.

[0119] The first arc segment 102 and the second arc segment 103 are formed by bending pipes from the pipe fitting base material.

[0120] The third straight pipe section 116 has a first pair of pipe sections 117 at one end, and the fifth straight pipe section 125 has a second pair of pipe sections 126 at the other end. The first pair of pipe sections 117 and the second pair of pipe sections 126 are used to connect with other pipe fittings.

[0121] The first pair of pipe sections 117 or the second pair of pipe sections 126 are flared or reduced in diameter to facilitate connection with other pipe fittings.

[0122] A transition section 101 is formed between the third straight pipe section 116 and the first pipe section 117, and between the fifth straight pipe section 125 and the second pipe section 126, to prevent stress concentration between the flared section and other pipe sections, which could cause the pipe wall to become too thin at the corresponding position and lead to breakage.

[0123] The inner diameter d1 of each of the first arc-shaped pipe section 111, the first straight pipe section 113, the second straight pipe section 114, the first bend pipe section 115, and the third straight pipe section 116 on the first piping unit 110 is equal, and the outer diameter D1 of each of the pipe sections is equal.

[0124] The inner diameter d2 of each pipe on the second arc-shaped pipe section 121, the insertion pipe section 122, the fourth straight pipe section 123, the second bend pipe section 124, and the fifth straight pipe section 125 of the first piping unit 110 is equal, and the outer diameter D2 of each pipe is equal.

[0125] The matching pipe section 112, the first pair of pipe sections 117 or the second pair of pipe sections 126 are flared, and their inner diameter is slightly larger than d1.

[0126] The length of the insertion pipe section 122 located outside the mating pipe section 112 is equal to the length of the first straight pipe section 113, and both are not less than twice the outer diameter of the first arc-shaped pipe section 111.

[0127] Combination Figure 12 , Figure 14 The radii r1 and r2 of the circles containing the center lines of the arc segments contained in the first and second bend pipe segments are not less than twice the outer diameter D1 of the first arc pipe segment 111.

[0128] The radius r3 of the circle containing the center lines of the first arc-shaped pipe segment 111 and the second arc-shaped pipe segment 121 is not less than twice the outer diameter D1 of the first arc-shaped pipe segment 111.

[0129] The dimensions of the aforementioned pipe sections are designed to facilitate manufacturing processes.
