Summary of the Invention

Problems to be Solved by the Invention

[0003] However, in the conventional support structure, there is a problem that when the compressor operates at a low rotation speed, the compressor and the vibration isolator resonate, and the vibration of the compressor in the horizontal direction may increase.

Means for Solving the Problems

[0004] The support structure of the first aspect is a support structure for supporting a compressor on an installation portion via a support member fixed to the lower portion of the compressor body. The support structure includes a first member, a first vibration damping member, and a second vibration damping member. The first member is disposed radially outside the compressor, one is assembled with the support member, the other is fixed to the installation portion, and supports the compressor from below. The first vibration damping member is disposed below the upper surface of the support member in the vertical direction between the installation portion and the support member, and is formed such that a through hole through which the first member passes extends in the vertical direction, and attenuates the vertical vibration of the compressor. The second vibration damping member is disposed on the upper surface of the support member, and attenuates the horizontal vibration and the circumferential vibration of the compressor. The second vibration damping member is disposed such that a second straight line or a third straight line passing through a fixing portion fixed to the support member and a position where the first member and the support member are assembled extends in an angular direction greater than 0° and less than 180° with respect to a first straight line passing through the central axis of the compressor body and a position where the first member and the support member are assembled.

[0005] In this support structure, vertical vibration, horizontal vibration, and circumferential vibration of the compressor can be suppressed.

[0006] The support structure of the second aspect is the support structure of the first aspect, and the second vibration damping member is arranged such that the second straight line or the third straight line extends in an angular direction in the range of 45° to 135° with respect to the first straight line.

[0007] In this support structure, by arranging the second straight line or the third straight line to extend in an angular direction in the range of 45° to 135° with respect to the first straight line, horizontal vibration and circumferential vibration of the compressor can be efficiently suppressed.

[0008] The support structure of the third aspect is the support structure of the first aspect or the second aspect, and there is a gap in the horizontal direction between the inner peripheral surface of the through hole formed in the first vibration damping member and the outer peripheral surface of the first member.

[0009] In this support structure, since there is a gap in the horizontal direction between the first vibration damping member and the first member, the first member directly hits the second vibration damping member, and the second vibration damping member can absorb the horizontal vibration of the compressor.

[0010] The support structure of the fourth aspect is any one of the support structures from the first aspect to the third aspect, and the second vibration damping member is in contact with the support member without a gap at the fixing portion where the second vibration damping member is fixed to the support member. The second vibration damping member is in contact with the first member without a gap at the fixing portion where the second vibration damping member is fixed to the first member.

[0011] In this support structure, since the second vibration damping member is connected to the support member and the first member, the horizontal vibration of the compressor can be attenuated by the attenuation of the second vibration damping member between the support member fixed to the casing of the compressor and the first member fixed to the installation portion.

[0012] The support structure of the fifth aspect is any one of the support structures from the first aspect to the fourth aspect, and a plurality of second vibration damping members are arranged for one first member.

[0013] In this support structure, by using a plurality of second vibration damping members, even when the compressor vibrates in a plurality of different horizontal directions, the vibration can be easily suppressed.

[0014] The support structure of the sixth aspect is any one of the support structures from the first aspect to the fifth aspect, and the second vibration damping member includes a spring. The fixed portion where the second vibration damping member is fixed to the support member is a convex portion included in the support member and in contact with one end of the spring. The second straight line is a straight line passing through the convex portion and the position where the first member and the support member are assembled, and extends along the expansion and contraction direction of the spring.

[0015] In this support structure, since the second vibration damping member includes a spring, the vibration in the horizontal direction and the circumferential direction of the compressor are suppressed by the attenuation of the spring.

[0016] The support structure of the seventh aspect is any one of the support structures from the first aspect to the fifth aspect, and the second vibration damping member includes rubber. When the rubber is a rectangular or elliptical plate-shaped rubber in a top view, the fixed portion where the second vibration damping member is fixed to the support member is a convex portion included in the support member and in contact with the end portion in the major axis direction of the rubber. The third straight line is a straight line passing through the end portion in the major axis direction of the rubber and the position where the first member and the support member are assembled.

[0017] In this support structure, by fixing the end portion in the major axis direction of the rectangular or elliptical rubber to the convex portion of the support member, the vibration in the horizontal direction and the circumferential direction of the compressor can be suppressed by the elasticity of the rubber.

[0018] The support structure of the eighth aspect is a support structure for supporting a compressor on an installation part. The support structure includes a support member, a first member, a first vibration damping member, and a second vibration damping member. The support member is fixed to the lower part of the compressor body. The first member is arranged on the outer side in the radial direction of the compressor, one end of which is assembled with the support member, the other end of which is fixed to the installation part, and supports the compressor from below. The first vibration damping member is arranged below the upper surface of the support member in the vertical direction between the installation part and the support member, and is formed such that a through hole through which the first member passes extends in the vertical direction, and attenuates the vertical vibration of the compressor. The second vibration damping member is arranged on the upper surface of the support member, and attenuates the horizontal vibration and the circumferential vibration of the compressor. The entire or part of the outer peripheral edge of the second vibration damping member is in contact with the support member without a gap at a fixing part fixed to the support member. The inner peripheral edge of the second vibration damping member is in contact with the first member without a gap at a fixing part fixed to the first member.

[0019] In this support structure, the vertical vibration, the horizontal vibration, and the circumferential vibration of the compressor can be suppressed.

[0020] The support structure of the ninth aspect is any one of the support structures of the first to eighth aspects, and the support member includes a plurality of support legs. The first member and each support leg are assembled.

[0021] In this support structure, since the first member and each support leg are assembled, even for a large compressor, the vertical vibration, the horizontal vibration, and the circumferential vibration of the compressor can be suppressed.

[0022] The support structure of the tenth aspect is any one of the support structures of the first to eighth aspects, and the support member includes a single plate-shaped bracket. There are three or more first members. The first member and the bracket are assembled.

[0023] In this support structure, since there are three or more first members and the first member and the bracket are assembled, even for a large compressor, the vertical vibration, the horizontal vibration, and the circumferential vibration of the compressor can be suppressed.

[0024] The heat source unit according to the 11th aspect includes a compressor, an installation part, and the support structure according to any one of claims 1 to 10.

[0025] In this heat source unit, it is possible to suppress the vertical vibration, horizontal vibration, and circumferential vibration of the compressor included in the heat source unit.

[0026] The refrigeration device according to the 12th aspect includes a heat source unit and a utilization unit. The heat source unit has a compressor, an installation part, and the support structure according to any one of claims 1 to 10.

[0027] In this refrigeration device, it is possible to suppress the vertical vibration, horizontal vibration, and circumferential vibration of the compressor included in the refrigeration device.

Mode for Carrying Out the Invention

[0029] Hereinafter, embodiments of the support structure of the present disclosure and modifications thereof will be described with reference to the drawings. Note that the specific configuration of the support structure of the present disclosure is not limited to the following embodiments and modifications thereof, and can be changed without departing from the gist of the invention.

[0030] (1) Basic configuration of the refrigeration device FIG. 1 is a schematic configuration diagram of an air conditioner 1 which is an example of a refrigeration device adopting the support structure of the compressor 21 according to the present embodiment.

[0031] The air conditioner 1 is a device capable of performing cooling and heating of the interior of a building or the like by performing a vapor compression refrigeration cycle. The air conditioner 1 is mainly configured by connecting a heat source unit 2 and a utilization unit 4. Here, the heat source unit 2 and the utilization unit 4 are connected via a liquid refrigerant communication pipe 5 and a gas refrigerant communication pipe 6. In other words, the vapor compression refrigerant circuit 10 of the air conditioner 1 is configured by connecting the heat source unit 2 and the utilization unit 4 via the refrigerant communication pipes 5 and 6.

[0032] (1-1) Utilization unit The utilization unit 4 is installed indoors and constitutes a part of the refrigerant circuit 10. The utilization unit 4 mainly has a utilization-side heat exchanger 41.

[0033] The utilization-side indoor heat exchanger 41 is a heat exchanger that functions as an evaporator of the refrigerant to cool the indoor air during the cooling operation and functions as a radiator of the refrigerant to heat the indoor air during the heating operation. The liquid side of the utilization-side heat exchanger 41 is connected to the liquid refrigerant communication pipe 5, and the gas side of the utilization-side heat exchanger 41 is connected to the gas refrigerant communication pipe 6.

[0034] The utilization unit 4 has a utilization fan 42 for sucking indoor air into the utilization unit 4, exchanging heat with the refrigerant in the utilization-side heat exchanger 41, and then supplying it into the room as supply air. That is, the utilization unit 4 has the utilization fan 42 as a fan that supplies indoor air, which is a heating source or a cooling source of the refrigerant flowing through the utilization-side heat exchanger 41, to the utilization-side heat exchanger 41.

[0035] (1-2) Heat source unit The heat source unit 2 is installed outdoors and constitutes a part of the refrigerant circuit 10. The heat source unit 2 mainly includes a compressor 21, a four-way switching valve 22, a heat source-side heat exchanger 23, an expansion valve 24, a liquid-side shutoff valve 25, a gas-side shutoff valve 26, and an accumulator 27.

[0036] The compressor 21 is a device that compresses the low-pressure refrigerant in the refrigeration cycle until it becomes high-pressure. The compressor 21 has a hermetic structure in which a positive-displacement compression element such as a rotary type is rotationally driven by a compressor motor (hereinafter also referred to as a motor) 21a. The four-way switching valve 22 switches the flow of the refrigerant in the refrigerant circuit 10 between the solid line (during cooling operation) and the broken line (during heating operation) in FIG. 1.

[0037] (2) Basic operation of the air conditioner As a basic operation, the air conditioner 1 is capable of performing a cooling operation and a heating operation.

[0038] During the cooling operation, the refrigerant discharged from the compressor 21 passes through the heat source-side heat exchanger 23, the expansion valve 24, the utilization-side heat exchanger 41, and the accumulator 27, and is inhaled into the compressor 21 again. In other words, during the cooling operation, the heat source-side heat exchanger 23 functions as a radiator, and the utilization-side heat exchanger 41 functions as an evaporator.

[0039] During the heating operation, the refrigerant discharged from the compressor 21 passes through the utilization-side heat exchanger 41, the expansion valve 24, the heat source-side heat exchanger 23, and the accumulator 27, and is inhaled into the compressor 21 again. In other words, during the heating operation, the utilization-side heat exchanger 41 functions as a radiator, and the heat source-side heat exchanger 23 functions as an evaporator.

[0040] (3) Basic configuration of the heat source unit Next, with reference to FIGS. 1 to 3, the basic configuration of the heat source unit 2 will be described. Here, FIG. 2 is a perspective view showing the appearance of the heat source unit 2. FIG. 3 is a perspective view showing a state in which the top plate, front plate, and side plates of the heat source unit 2 are removed.

[0041] The heat source unit 2 mainly includes a unit casing 51, and devices and piping including a compressor 21, a four-way switching valve 22, a heat source-side heat exchanger 23, an expansion valve 24, shut-off valves 25 and 26, an accumulator 27, and refrigerant pipes 31 to 35 connecting these devices, and an outdoor fan 36 and an outdoor fan motor 36a. The heat source unit 2 also has a bottom plate 52 as an installation part and a support structure.

[0042] The compressor 21 is a vertical cylindrical hermetic compressor and is placed on the bottom plate 52 as an installation part.

[0043] (4) Configuration of the compressor FIG. 4 shows a cross-sectional view of the compressor 21 to which the accumulator 27 is connected. The compressor 21 has a compressor body and a support member. The compressor 21 is a single-cylinder type rotary compressor. The rotary compressor 21 mainly includes, as a compressor body, a casing 110, a compression mechanism 115, a motor 21a, an inlet pipe 119, and a discharge pipe 32.

[0044] The compressor 21 is configured such that the outlet pipe 154 of the accumulator 27 is connected to the inlet pipe 119 of the compressor 21. The accumulator 27 has the suction pipe 31 connected thereto. When the compressor 21 operates, the low-pressure refrigerant in the refrigeration cycle flows into the cylinder 124 through the suction pipe 31 connected to the accumulator 27, the outlet pipe 154, and the inlet pipe 119 of the compressor 27. The low-pressure refrigerant in the refrigeration cycle that has flowed into this cylinder 124 is compressed to a high pressure in the refrigeration cycle and discharged into the space within the casing 110. Further, the refrigerant discharged into this casing 110 is sent to the heat source side heat exchanger 23.

[0045] (4-1) Casing The casing 110 is composed of a cylindrical body portion 111, a bowl-shaped top portion 112, and a bowl-shaped bottom portion 113. The top portion 112 is hermetically connected to the upper end portion of the body portion 111. The bottom portion 113 is hermetically connected to the lower end portion of the body portion 111.

[0046] The casing 110 is formed of a rigid member that is less likely to deform and break due to changes in pressure and temperature in the internal and external spaces of the casing 110. The casing 110 is installed such that the cylindrical axial direction of the body portion 111 is along the vertical direction. The lower part of the internal space of the casing 110 is an oil storage portion 110a where lubricating oil is stored. The lubricating oil is refrigeration machine oil used to improve the lubricity of the sliding portions existing in the internal space of the casing 110.

[0047] The casing 110 mainly houses a compression mechanism 115, a motor 116, and a crankshaft 117. The compression mechanism 115 is connected to the motor 116 via the crankshaft 117. The casing 110 is hermetically connected to the inlet pipe 119 and the discharge pipe 32 by welding or the like.

[0048] (4-2) Compression mechanism The compression mechanism 115 compresses the low-pressure refrigerant flowing through the refrigerant circuit and discharges it into the high-pressure space S3 inside the casing 110. The compression mechanism 115 is immersed in the lubricating oil stored in the oil storage portion 110a. The lubricating oil in the oil storage portion 110a is supplied to the sliding portion of the compression mechanism 115 by a differential pressure or the like.

[0049] The compression mechanism 115 mainly includes a piston 121, a front head 123, a cylinder 124, and a rear head 125. The cylinder 124 has a cylinder chamber 124a which is a cylindrical space. The upper opening of the cylinder chamber 124a is closed by the front head 123. The lower opening of the cylinder chamber 124a is closed by the rear head 125. The front head 123, the cylinder 124, and the rear head 125 are integrally fastened by bolts. The cylinder chamber 124a is connected to the inlet pipe 119. The low-pressure refrigerant before being compressed flows through the inlet pipe 119 and is supplied to the cylinder chamber 124a.

[0050] The piston 121 is disposed in the cylinder chamber 124a. The piston 121 is connected to the crankshaft 117. When the crankshaft 117 rotates, the piston 121 in the cylinder chamber 124a revolves while contacting the inner peripheral surface of the cylinder 124. Due to the revolving motion of the piston 121, the volume of the cylinder chamber 124a partitioned by the piston 121 periodically increases and decreases. Thereby, the refrigerant in the cylinder chamber 124a is compressed. The refrigerant compressed in the cylinder chamber 124a is discharged into the high-pressure space S3 through the discharge port 123b formed in the front head 123.

[0051] A discharge valve 123c that closes the discharge port 123b is attached to the upper surface of the front head 123. The discharge valve 123c is a valve for preventing the backflow of the refrigerant from the high-pressure space S3 to the cylinder chamber 124a. The discharge valve 123c is lifted upward by the increase in the pressure of the refrigerant inside the discharge port 123b. Thereby, the discharge port 123b communicates with the high-pressure space S3.

[0052] (4-3) Motor The motor 21a is housed inside the casing 110 and installed above the compression mechanism 115. The motor 21a mainly consists of a stator 151 fixed to the inner wall surface of the casing 110 and a rotor 152 rotatably housed with an air gap provided inside the stator 151.

[0053] The stator 151 has a stator core 161 and a pair of insulators 162 attached to both end faces of the stator core 161 in the vertical direction. The stator core 161 has a cylindrical portion and a plurality of teeth (not shown) protruding radially inward from the inner peripheral surface of the cylindrical portion. The teeth of the stator core 161 are wound with a conducting wire together with the pair of insulators 162. Thereby, a coil 172a is formed on each tooth of the stator core 161.

[0054] On the outer surface of the stator 151, a plurality of core cut portions (not shown) are provided which are formed with notches extending from the upper end surface to the lower end surface of the stator 151 and at predetermined intervals in the circumferential direction. The core cut portions form a motor cooling passage extending in the vertical direction between the body portion 111 of the casing 110 and the stator 151. The refrigerant discharged from the compression mechanism 115 into the high-pressure space S3 flows upward through the motor cooling passage and is then discharged from the discharge pipe 32 to the outside of the casing 110.

[0055] The rotor 152 is composed of a plurality of metal plates laminated in the vertical direction. The rotor 152 is connected to the compression mechanism 115 via a crankshaft 117. The crankshaft 117 vertically penetrates the rotation center of the rotor 152.

[0056] (4-4) Inlet pipe The inlet pipe 119 is a pipe that horizontally penetrates the body portion 111 of the casing 110. The inlet pipe 119 is a pipe for supplying refrigerant to the cylinder chamber 124a of the compression mechanism 115.

[0057] (4-5) Discharge pipe The discharge pipe 32 is a pipe that horizontally penetrates the top 112 of the casing 110. The discharge pipe 32 is a pipe for supplying the refrigerant compressed by the compression mechanism 115 to the refrigerant circuit.

[0058] (4-6) Support member A single plate-shaped bracket (support member) 60 is fixed to the lower part of the casing 110 of the compressor body (see Fig. 5). The compressor 21 is supported on the bottom plate 52, which is the installation part, via the bracket 60.

[0059] (5) Compressor support structure The support structure of the compressor 21 in this embodiment is a support structure that supports the compressor 21 on the bottom plate (installation part) 52 via a bracket 60 fixed to the lower part of the compressor body. The support structure of the compressor 21 includes a support bolt (first member) 80, a vibration-proof rubber (first vibration damping member) 70, and a spring (second vibration damping member) 90.

[0060] Fig. 5 is a perspective view of the vicinity of the lower part of the compressor 21. As shown in Fig. 5, a bracket 60 for supporting the compressor 21 on the bottom plate 52 of the heat source unit 2 is provided at the lower part of the compressor body. Here, the bracket 60 is provided at the lower part of the casing 110 of the compressor 21.

[0061] Fig. 6A is a side view of the compressor 21 to which the accumulator 27 is connected, and Fig. 6B is a top view of the compressor 21 to which the accumulator 27 is connected.

[0062] In Figs. 6A and 6B, arrows indicating the X-axis direction, Y-axis direction, and Z-axis direction are shown. The X-axis direction is a direction in the horizontal plane connecting the central axis A1 of the compressor body and the central axis (not shown) of the accumulator 27. The Y-axis direction is a direction in the horizontal plane orthogonal to the X-axis direction. The Z-axis direction is a direction orthogonal to the X-axis direction and the Y-axis direction, and is the vertical direction.

[0063] During the operation of the compressor 21, vibrations occur in the vertical direction (Z-axis direction) of the compressor 21, in the horizontal direction (direction within the horizontal plane including the X-axis direction and the Y-axis), and in the circumferential direction (rotation direction R1 with the central axis A1 of the compressor body, which is the Z-axis direction, as the rotation axis).

[0064] The support structure of the compressor 21 in this embodiment includes a vibration isolation rubber 70 to attenuate the vertical vibration of the compressor 21, and a spring 90 to attenuate the horizontal vibration and the circumferential vibration of the compressor 21.

[0065] FIG. 7 is a top view of the compressor 21 provided with the support structure. As shown in FIGS. 5 and 7, the bracket 60 is a triangular member fixed to the lower part of the compressor body. The bracket 60 has a fitting hole 61 (see FIG. 8) formed in a portion near the corner of the bracket 60 outside the compressor 21. The shape of the bracket 60 is not limited to a triangular shape and may be another shape.

[0066] (5-1) First member The support bolt (first member) 80 is a metal member that penetrates the vibration isolation rubber 70 in the vertical direction to connect the bracket 60 and the bottom plate 52. As shown in FIGS. 5 and 7, the support bolt 80 is disposed outside the compressor 21.

[0067] FIG. 8 is a cross-sectional view of the support structure of the compressor 21. As shown in FIG. 8, one end of the support bolt 80 is assembled with the bracket 60, and the other end is fixed to the bottom plate 52, which is the installation part. Thereby, the support bolt 80 supports the compressor 21 from below.

[0068] (5-2) First vibration damping member The vibration isolation rubber (first vibration damping member) 70 is a rubber member disposed between the bracket 60 and the bottom plate 52.

[0069] As shown in FIG. 8, on the bottom plate 52 as the installation part, a support bolt 80 and a vibration isolation rubber 70 are provided at positions corresponding to the fitting hole 61 of the bracket 60 of the compressor 21.

[0070] The vibration isolator rubber 70 is disposed below the upper surface of the bracket 60 of the compressor 21 in the vertical direction between the bottom plate 52 as the installation part and the bracket 60. The vibration isolator rubber 70 is formed such that a through hole 71 through which the support bolt 80 penetrates extends in the vertical direction, and attenuates the vertical vibration of the compressor 21. The support bolt 80 penetrates upward from the lower surface of the bottom plate 52 through the bottom plate 52 and the vibration isolator rubber 70.

[0071] Between the upper end of the support bolt 80 and the upper surface of the bracket 60 of the compressor 21, the support bolt 80 is in contact with the two springs 90a and 90b without a gap. And a seated nut 81 is screwed onto the upper end of the support bolt 80.

[0072] The vibration isolator rubber 70 is a cylindrical member in which a through hole 71 for the support bolt 80 penetrating in the vertical direction is formed. Here, let the outer peripheral surface of the vibration isolator rubber 70 be the outer peripheral surface 70a.

[0073] The upper part of the through hole 71 is an upper through hole 71a having an inner diameter larger than the outer diameter of the threaded portion of the support bolt 80, and the lower part of the through hole 71 is a lower through hole 71b having an inner diameter substantially the same as the outer diameter of the threaded portion of the support bolt 80. Here, let the inner peripheral surface of the upper part of the through hole 71 for the support bolt 80 formed in the vibration isolator rubber 70 be the inner peripheral surface 70b. Also, let the inner peripheral surface of the upper part of the through hole 71 formed in the vibration isolator rubber 70 be the inner peripheral surface 70c. Also, let the outer peripheral surface of the support bolt 80 be the outer peripheral surface 80a. There is a gap in the horizontal direction between the inner peripheral surface 70b of the through hole 71 formed in the vibration isolator rubber 70 and the outer peripheral surface 80a of the support bolt 80.

[0074] An upper end fitting portion 72 that is inserted and fitted into the fitting hole 61 of the bracket 60 of the compressor 21 is formed at the upper end of the vibration isolator rubber 70.

[0075] The lower part of the upper fitting portion 72 of the vibration isolator rubber 70 forms a rubber main body portion 73 as the portion between the bracket 60 and the bottom plate 52 of the vibration isolator rubber 70 in the vertical direction. Here, the upper end surface of the rubber main body portion 73 forms a surface larger than the outer diameter of the upper fitting portion 72 and is in contact with the lower surface of the peripheral portion of the fitting hole 61 of the bracket 60. Also, the lower end surface of the rubber main body portion 73 forms a surface larger than or equal to the outer diameter of the upper end surface of the rubber main body portion 73 and is in contact with the upper surface of the bottom plate 52. Note that the upper fitting portion 72 may not be formed at the upper end of the vibration isolator rubber 70. When the upper fitting portion 72 is not formed, the vibration isolator rubber 70 is disposed below the lower surface of the bracket 60 between the bracket 60 and the bottom plate 52 in the vertical direction.

[0076] (5-3) Second vibration damping member The spring (second vibration damping member) 90 is a metal member disposed between the bracket 60 and the support bolt 80. As shown in FIG. 8, the spring 90 is disposed on the bracket 60. Also, the bracket 60 has a convex portion (fixing portion) 95 on the upper surface of the bracket 60 to which the spring 90 is fixed.

[0077] A plurality of springs 90 are arranged for one support bolt 80. In the present embodiment, as shown in FIG. 8, two springs 90a and 90b are installed for one support bolt 80. Also, the bracket 60 has a convex portion 95a in contact with the spring 90a and a convex portion 95b in contact with the spring 90b on the upper surface of the bracket 60. The two convex portions 95a and 95b are provided at opposing positions around the support bolt 80. The two convex portions 95a and 95b are provided at positions away from the support bolt 80 such that the distance between the convex portion 95a and the convex portion 95b is larger than or equal to the outer diameter of the lower end surface of the rubber main body portion 73 of the vibration isolator rubber 70. Note that the positions of the convex portions 95a and 95b are not limited to this.

[0078] The bracket 60 is in contact with one end of the spring 90 without a gap. The support bolt 80 is in contact with the other end of the spring 90 without a gap. In the present embodiment, as shown in FIG. 8, at the convex portion 95a where one end of the spring 90a is fixed to the bracket 60, by being arranged so as to be in contact with the convex portion 95a, one end of the spring 90a is in contact with the bracket 60 without a gap. Also, at the fixing portion where the other end of the spring 90a is fixed to the support bolt 80, by being arranged so as to be in contact with the support bolt 80, the other end of the spring 90a is in contact with the support bolt 80 without a gap. Further, at the convex portion 95b where one end of the spring 90b is fixed to the bracket 60, by being arranged so as to be in contact with the convex portion 95b, one end of the spring 90b is in contact with the bracket 60 without a gap. Also, at the fixing portion where the other end of the spring 90b is fixed to the support bolt 80, by being arranged so as to be in contact with the support bolt 80, the other end of the spring 90b is in contact with the support bolt 80 without a gap. The number of springs 90 is not limited to two, and may be three or more.

[0079] The spring 90 is disposed on the upper surface of the bracket 60 and attenuates the horizontal vibration and the circumferential vibration of the compressor 21.

[0080] The spring 90 is arranged such that a second straight line L2 passing through the convex portion 95 to which the spring 90 is fixed to the bracket 60 and the position where the support bolt 80 and the bracket 60 are assembled extends in an angular direction greater than 0° and less than 180° with respect to a first straight line L1 passing through the central axis A1 of the compressor body and the position where the support bolt 80 and the bracket 60 are assembled.

[0081] The spring 90 is arranged such that the second straight line L2 extends in an angular direction in a range preferably from 45° to 135°, more preferably from 60° to 120°, and even more preferably from 75° to 105° with respect to the first straight line L1.

[0082] The spring 90 is most preferably arranged such that the second straight line L2 extends in an angular direction of 90° with respect to the first straight line L1. In other words, the spring 90 is most preferably arranged along the tangential direction of a virtual circle passing through the position where the support bolt 80 and the bracket 60 are assembled, with the central axis A1 of the compressor body as the center.

[0083] In the present embodiment, as shown in FIG. 7, for example, the spring 90a is arranged such that the second straight line L2 extends in an angular direction of approximately 90° with respect to the first straight line L1 when viewed from the central axis A1 of the compressor body.

[0084] Here, the bracket 60 is triangular, and three fitting holes 61 are provided in the vicinity of the corners of the bracket 60. However, depending on the shape of the bracket 60, there may be four or more fitting holes 61. When the bracket 60 is provided with three or more fitting holes 61, there are three or more support bolts 80 and three or more vibration isolators 70, respectively. Further, for each of the three or more support bolts 80, a plurality of springs 90 are arranged.

[0085] (6) Features (6-1) In the support structure according to this embodiment, the compressor 21 is supported on the bottom plate 52 via a bracket 60 fixed to the lower part of the compressor body. The support structure includes a support bolt 80, a vibration isolator 70, and a spring 90. The support bolt 80 is disposed on the outer side in the radial direction of the compressor 21, one end is assembled with the bracket 60, and the other end is fixed to the bottom plate 52 to support the compressor 21 from below. The vibration isolator 70 is disposed below the upper surface of the bracket 60 between the bottom plate 52 and the bracket 60 in the vertical direction, and is formed such that a through hole through which the support bolt 80 passes extends in the vertical direction, and attenuates the vertical vibration of the compressor 21. The spring 90 is disposed on the upper surface of the bracket 60 and attenuates the horizontal vibration and the circumferential vibration of the compressor 21. The spring 90 is arranged such that a second straight line L2 passing through a fixed portion fixed to the bracket 60 and a position where the support bolt 80 and the bracket 60 are assembled extends in an angular direction greater than 0° and less than 180° with respect to a first straight line L1 passing through the central axis A1 of the compressor body and a position where the support bolt 80 and the bracket 60 are assembled.

[0086] Conventionally, as a support structure for attenuating the vibration of a compressor, a support structure in which a bracket of the compressor is attached to a substrate via a vibration isolator is known.

[0087] In the conventional support structure, when the compressor is operated at a low rotation speed, for example, at a frequency of 4 to 5 Hz of the driving rotation speed in a motor, there is a problem that the amplitude in the rotation direction (circumferential direction) about the Z-axis direction (see FIG. 6B) at the low rotation speed becomes large. This is because the vibration isolator is soft and the natural frequencies of the compressor and the vibration isolator when vibrating in the rotation direction are low, resulting in resonance at low rotation speeds.

[0088] As a countermeasure for this problem, there is a method of replacing the vibration isolator with a hard material to suppress the amplitude. However, in this method, the natural frequency of the vibration isolator becomes high, and when the compressor is operated at a frequency of 10 Hz or more, for example, there is a problem that resonance occurs within the operating range of the compressor.

[0089] In this support structure, due to the damping of the spring 90, the amplitude during the operation of the compressor at low rotational speeds can be suppressed. Also, since the natural frequency of the vibration isolation rubber 70 does not change within the range of 5 to 7 Hz, resonance does not occur during the operation of the compressor at high rotational speeds.

[0090] In this support structure, by providing the vibration isolation rubber 70, the vertical vibration of the compressor 21 can be suppressed, and by providing the spring 90, the horizontal vibration and the circumferential vibration of the compressor 21 can be suppressed.

[0091] (6 - 2) In the support structure according to this embodiment, the spring 90 is arranged such that the second straight line L extends in the angular direction within the range of 45° to 135° with respect to the first straight line L1.

[0092] In this support structure, by arranging the second straight line L2 to extend in the angular direction within the range of 45° to 135° with respect to the first straight line L1, the horizontal vibration and the circumferential vibration of the compressor 21 can be efficiently suppressed.

[0093] (6 - 3) In the support structure according to this embodiment, there is a gap in the horizontal direction between the inner peripheral surface 70b of the through hole 71 formed in the vibration isolation rubber 70 and the outer peripheral surface 80a of the support bolt 80.

[0094] In this support structure, since there is a gap in the horizontal direction between the vibration isolation rubber 70 and the support bolt 80, the support bolt 80 directly contacts the spring 90, and the spring 90 can absorb the horizontal vibration of the compressor 21.

[0095] (6 - 4) In the support structure according to this embodiment, the spring 90 is in contact with the bracket 60 without a gap at the fixing portion where the spring 90 is fixed to the bracket 60. The spring 90 is in contact with the support bolt 80 without a gap at the fixing portion where the spring 90 is fixed to the support bolt 80.

[0096] In this support structure, the spring 90 is connected to the bracket 60 and the support bolt 80, so that the vibration in the horizontal direction of the compressor 21 can be attenuated by the attenuation of the spring 90 between the bracket 60 fixed to the casing 110 of the compressor 21 and the support bolt 80 fixed to the bottom plate 52.

[0097] (6-5) In the support structure according to the present embodiment, two springs 90a(90), 90b(90) are arranged for one support bolt 80.

[0098] In this support structure, by using two springs 90a and 90b, even when the compressor 21 vibrates in a plurality of different horizontal directions, the vibration can be easily suppressed.

[0099] (6-6) In the support structure according to the present embodiment, the second vibration damping member includes the spring 90. The fixing portion fixed to the bracket 60 of the second vibration damping member is a convex portion 95 included in the bracket 60 and in contact with one end portion of the spring 90. The second straight line L2 is a straight line passing through the convex portion 95 and the position where the support bolt 80 and the bracket 60 are assembled, and extends along the expansion and contraction direction of the spring 90.

[0100] In this support structure, since the second vibration damping member includes the spring 90, the vibration in the horizontal direction and the circumferential direction of the compressor are suppressed by the attenuation of the spring 90.

[0101] (6-7) In the support structure according to the present embodiment, the support member includes a single plate-shaped bracket 60. Three or more support bolts 80 are provided. The support bolt 80 and the bracket 60 are assembled.

[0102] In this support structure, by providing three or more support bolts 80 and assembling the support bolt 80 and the bracket 60, even for a large compressor, the vibration in the vertical direction, the horizontal direction, and the circumferential direction of the compressor can be suppressed.

[0103] (6-8) In the heat source unit 2 according to the present embodiment, a compressor 21, a bottom plate 52, and a support structure are provided.

[0104] In this heat source unit 2, it is possible to suppress the vertical vibration, horizontal vibration, and circumferential vibration of the compressor 21 included in the heat source unit 2.

[0105] (6-9) In the air conditioner 1 according to the present embodiment, a heat source unit 2 and a utilization unit 4 are provided. The heat source unit 2 has a compressor 21, a bottom plate 52, and a support structure.

[0106] In this air conditioner 1, it is possible to suppress the vertical vibration, horizontal vibration, and circumferential vibration of the compressor 21 included in the air conditioner 1.

[0107] (7) Modification (7-1) Modification 1A In the present embodiment, the case where two springs 90a and 90b are arranged as the second vibration damping member with respect to one support bolt 80 has been described. However, one spring 90 may be arranged with respect to one support bolt 80.

[0108] FIG. 9 is a cross-sectional view of the support structure of the compressor 21 in Modification 1A. In Modification 1A, one spring 90a is provided as the second vibration damping member. Since the configuration of the support structure of the compressor 21 in Modification 1A other than the spring 90 is the same as the configuration of the support structure of the compressor 21 in the present embodiment, detailed description thereof will be omitted.

[0109] As shown in FIG. 9, the bracket 60 has a convex portion 95a in contact with the spring 90a on the upper surface of the bracket 60. At the convex portion 95a where one end of the spring 90a is fixed to the bracket 60, by being arranged so as to be in contact with the convex portion 95a, one end of the spring 90a is in contact with the bracket 60 without a gap. Further, at the fixing portion where the other end of the spring 90a is fixed to the support bolt 80, by being arranged so as to be in contact with the support bolt 80, the other end of the spring 90a is in contact with the support bolt 80 without a gap.

[0110] In the support structure of Modification 1A, by arranging one spring 90a for one support bolt 80, for example, in the support structure of a small compressor, even if the number of springs 90 is one, the horizontal vibration and circumferential vibration of the compressor can be suppressed.

[0111] (7-2) Modification 1B In this embodiment, the case where the second vibration damping member is the spring 90 has been described, but the second vibration damping member may be the vibration isolation rubber 91.

[0112] The vibration isolation rubber (second vibration damping member) 91 is a rubber member disposed between the bracket 60 and the support bolt 80. The vibration isolation rubber 70 of the first vibration damping member and the vibration isolation rubber 91 of the second vibration damping member may be made of the same material or different materials. The vibration isolation rubber 70 of the first vibration damping member and the vibration isolation rubber 91 of the second vibration damping member are, for example, rubber members such as NR.

[0113] FIG. 10 is a top view of a compressor provided with the support structure of Modification 1B. FIG. 11 is a cross-sectional view of the 21 support structures of the compressor of Modification 1B. Since the configuration of the support structure of the compressor 21 of Modification 1B other than the vibration isolation rubber 91 is the same as the configuration of the support structure of the compressor 21 of this embodiment, detailed description thereof is omitted.

[0114] As shown in FIGS. 10 and 11, the vibration isolation rubber 91 is a rectangular plate-like member in a top view. The length of the long side of the vibration isolation rubber 91 is made larger than the outer diameter of the lower end surface of the rubber main body portion 73 of the vibration isolation rubber 70. Note that the size of the vibration isolation rubber 91 is not limited to this.

[0115] The vibration isolation rubber 91 is disposed on the bracket 60. Further, the vibration isolation rubber 91 has a through hole 92 through which the support bolt 80 passes. Here, the inner peripheral surface of the through hole 92 for the support bolt 80 formed in the vibration isolation rubber 91 is defined as the inner peripheral surface 91a.

[0116] The bracket 60 has a convex portion (fixing portion) 96 on the upper surface of the bracket 60 to which the vibration isolator 91 is fixed. The convex portion 96 is included in the bracket 60 and contacts the end portion of the vibration isolator 91 in the major axis direction. For one vibration isolator 91, there are two convex portions (fixing portions) 96a and 96b that contact the outer peripheral edge of the vibration isolator 91.

[0117] A part of the outer peripheral edge of the vibration isolator 91 is in contact with the bracket 60 without a gap at the convex portions 96a and 96b fixed to the bracket 60. The inner peripheral edge of the vibration isolator 91 is in contact with the support bolt 80 without a gap at the fixing portion fixed to the support bolt 80. In Modification 1B, as shown in FIG. 10, by arranging the side surface including the short side M1 of the vibration isolator 91 (the end portion of the vibration isolator 91 in the major axis direction) to contact the convex portion 96a, the bracket 60 is in contact with the side surface including the short side M1 of the vibration isolator 91 without a gap.

[0118] Also, by arranging the side surface including the short side M2 of the vibration isolator 91 (the end portion of the vibration isolator 91 in the major axis direction) to contact the convex portion 96b, the bracket 60 is in contact with the side surface including the short side M2 of the vibration isolator 91 without a gap. Further, the inner peripheral surface 91a of the through hole 92 of the vibration isolator 91 and the outer peripheral surface 80a of the support bolt 80 are in contact with each other without a gap.

[0119] The vibration isolator 91 is arranged on the upper surface of the bracket 60 and attenuates the horizontal vibration and circumferential vibration of the compressor 21.

[0120] The vibration isolator 91 is arranged such that a third straight line L3 passing through the end portion of the vibration isolator 91 in the major axis direction and the position where the support bolt 80 and the bracket 60 are assembled extends in an angular direction of 0° or more and less than 180° with respect to a straight line L1 passing through the central axis A1 of the compressor body and the position where the support bolt 80 and the bracket 60 are assembled.

[0121] The vibration isolator 91 is arranged such that the third straight line L3 extends in an angular direction in a range of preferably 45° to 135°, more preferably 60° to 120°, and even more preferably 75° to 105° with respect to the first straight line L1.

[0122] The vibration isolation rubber 91 is most preferably arranged such that the third straight line L3 extends in a direction at an angle of 90° with respect to the first straight line L1. In other words, the vibration isolation rubber 91 is most preferably arranged along the tangential direction of a virtual circle passing through the position where the support bolt 80 and the bracket 60 are assembled, with the central axis A1 of the compressor body as the center.

[0123] In Modification 1B, as shown in FIG. 10, the vibration isolation rubber 91 is arranged such that when viewed from the central axis A1 of the compressor body, the third straight line L3 extends in a direction at an angle of approximately 90° with respect to the first straight line L1.

[0124] In this way, in Modification 1B, as the second vibration damping member, a rectangular vibration isolation rubber 91 is used, and by fixing the end portions in the major axis direction of the rectangular vibration isolation rubber 91 to the convex portions 96 of the bracket 60, the elastic force of the rubber 91 can suppress the horizontal vibration and the circumferential vibration of the compressor 21.

[0125] In Modification 1B, the case where the bracket 60 has two convex portions 96a and 96b has been described, but it is not limited thereto. The number of convex portions 96 may be three or more according to the shape of the vibration isolation rubber 91. Also, a groove may be provided in the bracket 60 to fit the vibration isolation rubber 91 into the groove of the bracket 60. Thereby, the vibration isolation rubber 91 can be in contact with the bracket 60 without a gap.

[0126] Also, in Modification 1B, the case where the shape of the vibration isolation rubber 91 is a rectangular plate shape in top view has been described, but it is not limited thereto. The shape of the vibration isolation rubber 91 may be an elliptical plate shape in top view.

[0127] Also, the shape of the vibration isolation rubber 91 may be, for example, a square plate shape, a disk shape, etc. when viewed from above. For example, when the shape of the vibration isolation rubber 91 is a disk shape when viewed from above, the disk-shaped vibration isolation rubber 91 is fitted into a groove (fixing portion) provided on the upper surface of the bracket 60. Thereby, the entire outer peripheral edge of the vibration isolation rubber 91 is in contact with the bracket 60 without a gap in the groove (fixing portion) fixed to the bracket 60.

[0128] In the support structure of the compressor 21 of Modification 1B, the vibration isolation rubber 91 is used as the second vibration damping member, and the entire or a part of the outer peripheral edge of the vibration isolation rubber 91 is in contact with the bracket 60 without a gap in the fixing portion fixed to the bracket 60, and the inner peripheral edge of the rubber 91 is in contact with the support bolt 80 without a gap in the fixing portion fixed to the support bolt 80. Thus, the elastic property of the rubber can suppress the horizontal vibration and the circumferential vibration of the compressor 21.

[0129] (7-3) Modification 1C In this embodiment, the case where the support member is a single plate-shaped bracket 60 has been described, but the support member may be a plurality of support legs 62.

[0130] FIG. 12 is a perspective view of the vicinity of the lower part of the compressor 210 of Modification 1C. Since the support structure of the compressor 210 of Modification 1C is the same as the support structure of the compressor 21 of this embodiment except for the configuration other than the plurality of support legs 62, a detailed description thereof is omitted.

[0131] As shown in FIG. 12, support legs 62 for supporting the compressor 210 on the bottom plate 52 of the heat source unit 2 are provided at the lower part of the compressor body. Here, three support legs 62 are provided at intervals in the circumferential direction of the compressor 210. The support leg 62 is a substantially L-shaped member fixed to the lower side surface of the compressor body, and a fitting hole (not shown) penetrating in the vertical direction is formed in a portion protruding to the outer peripheral side from the side surface of the compressor body. Note that the number of the support legs 62 is not limited to three, and may be four or more. Also, the shape of the support leg 62 is not limited to the substantially L-shape, and may be another shape.

[0132] On the bottom plate 52 as the installation part, a support bolt 80 and a vibration isolator 70 are provided at positions corresponding to the support legs 62 of the compressor 210. The vibration isolator 70 is disposed between the support leg 62 provided on the compressor 210 and the bottom plate 52 located below it. The support bolt 80 penetrates upward from the lower surface of the bottom plate 52 through the bottom plate 52 and the vibration isolator 70.

[0133] Each support leg 62 is provided with a support bolt 80, a vibration isolator 70, and a spring 90. The support bolt 80 is assembled with each support leg 62. Further, the support leg 62 has a convex portion (fixing portion) 95 on the upper surface of the support leg 62 to which the spring 90 is fixed.

[0134] A plurality of springs 90 are arranged for one support bolt 80. In Modification 1C, as shown in FIG. 12, two springs 90a and 90b are arranged for one support bolt 80. Further, the support leg 62 has a convex portion 95a in contact with the spring 90a and a convex portion 95b in contact with the spring 90b on the upper surface of the support leg 62.

[0135] The support leg 62 is in contact with one end of the spring 90 without a gap. The support bolt 80 is in contact with the other end of the spring 90 without a gap. In Modification 1C, as shown in FIG. 12, at the convex portion 95a where one end of the spring 90a is fixed to the support leg 62, by being arranged so as to be in contact with the convex portion 95a, one end of the spring 90a is in contact with the support leg 62 without a gap. Also, at the fixing portion where the other end of the spring 90a is fixed to the support bolt 80, by being arranged so as to be in contact with the support bolt 80, the other end of the spring 90a is in contact with the support bolt 80 without a gap. Also, at the convex portion 95b where one end of the spring 90b is fixed to the support leg 62, by being arranged so as to be in contact with the convex portion 95b, one end of the spring 90b is in contact with the support leg 62 without a gap. Also, at the fixing portion where the other end of the spring 90b is fixed to the support bolt 80, by being arranged so as to be in contact with the support bolt 80, the other end of the spring 90b is in contact with the support bolt 80 without a gap. The number of springs 90 is not limited to two, and may be three or more. Also, one spring 90 may be arranged for one support bolt 80.

[0136] Here, three support legs 62 are provided side by side in the circumferential direction of the compressor 210, but four or more may be provided.

[0137] In Modification 1C, the case where the second vibration damping member is the spring 90 has been described, but it may have the vibration isolation rubber 91.

[0138] In the support structure of the compressor 210 of Modification 1C, by assembling the support bolts 80 and the respective support legs 62, even in the case of a large-sized compressor, the vertical vibration, horizontal vibration, and circumferential vibration of the compressor 210 can be suppressed.
