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] Due to the requirements of market cost competitiveness, compressor miniaturization is a development trend for key components such as air conditioner outdoor units. In order to meet the capacity requirements of air conditioners, it is necessary to speed up small-displacement compressors, which will significantly worsen compressor vibration.

[0003] In addition to increasing the noise of the outdoor unit, compressor vibration can also affect the connection stability of the piping components connected to the compressor, increasing the risk of piping components falling off and refrigerant leakage. In order to reduce the impact of vibration deterioration caused by compressor speed-up, some outdoor units of air conditioners suppress vibration by fixing the piping components to other support structures or adding counterweights to the piping components. However, the above vibration suppression methods will bring problems such as significantly increased costs, excessive stress, and poor manufacturability.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0011] In some embodiments of this application, a mating pipe section is provided at one end where the first piping unit is connected to the second piping unit, and a plug pipe section is provided at the other end where the second piping unit is connected to the first piping unit. The inner diameter of the mating pipe section is adapted to the outer diameter of the plug pipe section, and the plug pipe section is inserted into the mating pipe section.

[0012] The insertion pipe section and the mating pipe section achieve the initial connection and positioning of the first piping unit and the second piping unit. After the connection is completed, the connection between the insertion pipe section and the mating pipe section is welded.

The transition section is used to reduce stress concentration between the first straight pipe section and the mating pipe section, and to avoid problems such as the pipe wall being too thin at the connection between the first straight pipe section and the mating pipe section, which could lead to damage.

[0015] In some embodiments of this application, a second straight pipe segment is provided at one end of the first arc-shaped pipe segment away from the first straight pipe segment, and the other end of the second straight pipe segment is connected to the third straight pipe segment through a first bent pipe segment.

[0020] In some embodiments of this application, the other end of the third straight pipe segment is provided with a first pair of connecting pipe segments, and the other end of the fifth straight pipe segment is provided with a second pair of connecting pipe segments, the first pair of connecting pipe segments and the second pair of connecting pipe segments being used to connect with other pipe fittings.

[0021] In some embodiments of this application, transition portions are formed between the third straight pipe segment and the first connecting pipe segment, and between the fifth straight pipe segment and the second connecting pipe segment.

[0022] The transition section is used to avoid problems such as excessively thin pipe walls and pipe wall damage caused by direct bending between the third straight pipe section and the first paired pipe section, and between the fifth straight pipe section and the second paired pipe section.

[0027] On the other hand, this application also proposes an outdoor unit for an air conditioner, which includes:

[0028] The outer casing includes an installation cavity formed by a top plate, a bottom plate, and side plates;

[0029] A compressor, which is disposed within the mounting cavity;

[0030] A piping assembly connected to the compressor, the piping assembly including an annular pipe section;

[0031] At least a portion of the annular pipe section is a spatial annular structure, and the annular pipe section is configured such that both ends of the annular pipe section are connected to other pipe fittings to absorb the vibration energy during the operation of the compressor.

[0032] Compared with the prior art, the advantages and positive effects of this utility model are:

[0033] The outdoor unit of the air conditioner involved in this application includes a piping assembly connected to the compressor, comprising a first piping unit and a second piping unit. The first piping unit includes a first arc-shaped pipe segment, and the second piping unit includes a second arc-shaped pipe segment. The first and second arc-shaped pipe segments are arranged in a ring. That is, the piping assembly is a three-dimensional ring structure. This structure can absorb vibration energy in three directions in space, which is beneficial to reduce the outward transmission of compressor vibration, reduce noise, and improve the stability of the piping assembly connection.

[0034] In addition, the three-dimensional annular piping assembly can rotate arbitrarily along the preset central axis. Therefore, the installation angle can be determined according to the actual position allowed by space in the installation cavity of the outer shell. It is highly flexible and can be easily and quickly connected with other pipe fittings with less impact from space limitations.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] Combination Figure 3 , Figure 4 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.

[0074] 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.

[0075] 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.

[0076] Specifically, a mating pipe section 112 is provided at one end of the first piping unit 110 and the second piping unit 120, and a plug pipe section 122 is provided at the other end of the second piping unit 120 and the first piping unit 110. The inner diameter of the mating pipe section 112 is adapted to the outer diameter of the plug pipe section 122, and the plug pipe section 122 is inserted into the mating pipe section 112.

[0077] 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.

[0078] 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.

[0079] refer to Figure 5 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.

[0080] 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.

[0081] 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 bent pipe section 115.

[0082] The second straight pipe section 114 and the third straight pipe section 116 are located on both sides of the first bent pipe section 115, which facilitates the clamping and positioning of the first piping assembly 100 when processing the first bent pipe section 115.

[0083] refer to Figure 6 The second arc-shaped pipe section 121 is 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 bent pipe section 124.

[0084] Similarly, the fourth straight pipe segment 123 and the fifth straight pipe segment 125 are located at both ends of the second bent pipe segment 124, which facilitates the clamping and positioning of the second piping assembly 100 when processing the second bent pipe segment 124.

[0085] The first bent pipe section 115 and the second bent 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.

[0086] For example, but not limited to, in Figure 4 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 bent 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 bent 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.

[0087] 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, which are arranged in an S-shape in opposite directions.

[0088] The first arc segment 102 and the second arc segment 103 are formed by bending pipes from the pipe fitting base material.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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 bent 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.

[0093] The inner diameter d2 of each pipe diameter on the second arc-shaped pipe section 121, the insertion pipe section 122, the fourth straight pipe section 123, the second bent pipe section 124, and the fifth straight pipe section 125 on the first piping unit 110 is equal, and the outer diameter D2 of each pipe diameter is equal.

[0094] 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.

[0095] 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.

[0096] refer to Figure 5 , Figure 7 The radii r1 and r2 of the circles containing the center lines of the arc segments included in the first bent pipe segment 115 and the second bent pipe segment 124 are not less than twice the outer diameter D1 of the first arc-shaped pipe segment 111.

[0097] 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.

[0098] The above-mentioned pipe section size limits are designed to facilitate the processing technology. When bending pipes, conventional pipe bending machines are generally required to have a bending radius greater than twice the pipe diameter, and the length of the straight section used for clamping the pipe must also be greater than twice the pipe diameter.

[0099] On the other hand, this application also proposes an outdoor unit for an air conditioner, which includes an outer casing and working components such as a compressor 200 and a heat exchanger installed in the outer casing. The compressor 200 and the heat exchanger are connected by a piping assembly 100.

[0100] The outer casing includes an installation cavity formed by a top plate, a bottom plate 400, and side plates.

[0101] The compressor 200 is installed in the mounting cavity, and the bottom of the compressor 200 is provided with mounting feet 210.

[0102] The piping assembly 100 includes an annular pipe section; wherein at least a portion of the annular pipe section is a spatial annular structure, and the annular pipe section is configured such that both ends of the annular pipe section are connected to other pipe fittings respectively, for absorbing vibration energy during the operation of the compressor 200.

[0103] When the compressor 200 vibrates, it causes the piping assembly 100 to vibrate, resulting in excessive operating noise from the outdoor unit of the air conditioner. Under the influence of vibration, the connection stability of the piping assembly 100 is poor. The above-mentioned structural design of the piping assembly 100 can absorb vibration energy in three directions in space, which helps to reduce the outward transmission of vibration from the compressor 200, reduce noise, and improve the connection stability of the piping assembly 100.

[0104] It effectively reduces the vibration and stress of the air conditioner outdoor unit piping assembly 100, is easy to assemble and weld, and can be used as a general-purpose component to improve vibration and noise problems.

[0105] The piping assembly 100 can be installed in several ways, or in a combination of several of these ways.

[0106] Method 1

[0107] The annular pipe section of the piping assembly 100 can be formed by integral bending of the base material, and the two ends of the piping assembly 100 are used to connect with other pipe fittings.

[0108] Method 2:

[0109] The piping assembly 100 includes a first piping unit 110 and a second piping unit 120.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] Method 3

[0114] Based on Method 2, a mating pipe section 112 is provided at one end where the first piping unit 110 is connected to the second piping unit 120, and a plug pipe section 122 is provided at the other end where the second piping unit 120 is connected to the first piping unit 110. The inner diameter of the mating pipe section 112 is adapted to the outer diameter of the plug pipe section 122, and the plug pipe section 122 is inserted into the mating pipe section 112.

[0115] 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.

[0116] 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.

[0117] 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.

[0118] 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 bent pipe section 115.

[0119] The second arc-shaped pipe section 121 is 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 bent pipe section 124.

[0120] The first bent pipe section 115 and the second bent 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.

[0121] refer to Figure 8 , Figure 9In some other embodiments, the compressor 200 is provided with mounting feet 210 at the bottom, and the mounting feet 210 are connected to the housing through a support member 300. Specifically, the mounting feet 210 are supported on the base plate 400 through the support member 300.

[0122] Among them, a lower support gap is formed between the support member 300 and the base plate 400, an upper support gap is formed between the support member 300 and the compressor 200, and an installation port 301 is formed on the support member 300.

[0123] refer to Figure 10 , Figure 11 A vibration-absorbing component 330 is provided inside the mounting port 301. The vibration-absorbing component 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] In some embodiments of this application, the elastic part 332 includes two or more spring members evenly arranged along the periphery of the mass part 331, one end of the spring member being connected to the mass part 331, and the other end of the spring member being connected to the support member 300.

[0130] All spring components are of the same length to ensure that the force on the periphery of the mass part 331 is uniform.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] Combination Figure 8 , Figure 9 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.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] 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.

[0142] For details, please refer to the following: Figure 12 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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.

[0149] 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.

[0150] 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.

[0151] The first support component 310 and the second support component 320 help reduce the vibration transmission of the compressor 200 and further reduce noise.

[0152] 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).

[0153] Because the support member 300 has a bend 302 on its periphery, its structural strength is greatly improved. The position where the weight of the compressor 200 acts and the support position of the support member 300 are rationally designed, making the center of gravity of the structure stable and less prone to tipping over due to bumps during transportation. Compared with traditional structures, the vibration-damping and noise-reducing structural design of this compressor 200 occupies less space, is easy to install, and is easy to mass-produce.
