[0037] <First Embodiment> A specific example of the compressor of the first embodiment will be described below with reference to the drawings. However, this disclosure is not limited to these examples, and all modifications are intended to be included in the meaning and scope equivalent to the claims, as indicated by the claims.

[0038] In addition, regarding the descriptions and drawings of each embodiment, components having substantially the same or corresponding functional configurations may be denoted by the same reference numerals, thereby omitting redundant explanations. Furthermore, for ease of understanding, the scale of each part in the drawings may differ from the actual scale.

[0039] A degree of deviation is permissible in directions such as parallel, right angles, orthogonal, horizontal, vertical, up and down, left and right, and front and back, as long as it does not impair the effects of the embodiment. The shape of the corners is not limited to right angles and may be rounded. Parallel, right angles, orthogonal, horizontal, and vertical may include approximately parallel, approximately right angles, approximately orthogonal, approximately horizontal, and approximately vertical, respectively.

[0040] For example, "approximately parallel" means that two lines or two planes can be treated as parallel to each other within a manufacturingly acceptable range, even if they are not perfectly parallel. Similarly, "approximately right angle," "approximately perpendicular," "approximately horizontal," and "approximately vertical" are intended to apply as long as the relative positions of the two lines or two planes are within a manufacturingly acceptable range.

[0041] A compressor according to the first embodiment will now be described. The compressor according to the first embodiment comprises a compression mechanism, a shaft extending along a first direction and driving the compression mechanism, a motor rotating the shaft, a casing housing the compression mechanism, the shaft and the motor, and a first mounting plate for attaching the casing to an installation location. The first mounting plate in the compressor according to the first embodiment is fixed to the outer circumferential surface of the casing and has a first surface on which a vibration-damping member is arranged, and the first surface is inclined with respect to the first direction.

[0042] Figure 1 is a perspective view of compressor 1, which is an example of a compressor according to the first embodiment. Figure 2 is a side view of compressor 1, which is an example of a compressor according to the first embodiment. Figure 3 is a cross-sectional view of compressor 1, which is an example of a compressor according to the first embodiment. Figure 4 is a bottom view of compressor 1, which is an example of a compressor according to the first embodiment.

[0043] For ease of explanation, drawings may sometimes include a virtual three-dimensional coordinate system (XYZ Cartesian coordinate system) consisting of mutually orthogonal X, Y, and Z axes (XYZ axes). For example, when a coordinate axis perpendicular to the plane of the drawing is shown with a black circle inside, it indicates that the coordinate axis is pointing towards the viewer relative to the plane of the drawing. Conversely, when a coordinate axis is shown with an X inside, it indicates that the coordinate axis is pointing away from the plane of the drawing.

[0044] However, this coordinate system is defined for illustrative purposes only and is not limited to the orientation of the compressor, etc., according to this embodiment.

[0045] In the following diagram, the shaft 81 of the compressor 1 extends in the direction along the Z-axis, and the rollers 61 and 62 of the compressor 1 rotate in a plane parallel to the XY plane, which includes the X and Y axes. The direction along the Z-axis is the direction of gravity, and the directions along the X and Y axes are the horizontal directions.

[0046] A view of an object along the Z-axis, looking from the +Z side in the opposite direction of the Z-axis, is called a plan view. A view of an object along the Z-axis, looking from the +Z side in the opposite direction of the Z-axis, is called a bottom view. A view of an object along the Z-axis, looking from the -Z side in the direction of the Z-axis, is called a bottom view.

[0047] Compressor 1 is a rotary compressor. A rotary compressor is a compressor that compresses the gas in a compression chamber formed inside a cylinder by eccentrically rotating a roller inside the cylinder. Rotary compressors generally have vanes to partition the compression chamber. Rotary compressors include the so-called rolling piston type, in which a separate vane contacts the roller while the roller rotates eccentrically; the so-called swing type, in which a vane formed integrally with the roller swings along with the eccentric rotation of the roller; and the so-called hinge vane type, in which the tip of the vane is rotatably fitted into a recess on the outer surface of the roller while the roller rotates eccentrically.

[0048] The compressor according to this embodiment is not limited to a rotary compressor; it may also be a scroll compressor or other type of compressor.

[0049] Compressor 1 compresses a refrigerant. The refrigerant used in compressor 1 is, for example, carbon dioxide. However, the refrigerant is not limited to carbon dioxide; for example, fluorocarbon-based, hydrofluoroolefin-based, or hydrocarbon-based refrigerants may also be used. Compressor 1 comprises a compressor body 10 and an accumulator 20.

[0050] [Compressor body 10] The compressor body 10 comprises a casing 11, an intake pipe 12, an exhaust pipe 13, and power terminals 15. The casing 11 also includes a mounting plate 14 for installing the compressor body 10.

[0051] The casing 11 is a cylindrical sealed container. The casing 11 comprises a body portion 11a, an upper end plate 11b, and a lower end plate 11c. The end of the body portion 11a is closed by the upper end plate 11b and the lower end plate 11c, respectively. The casing 11 is sealed by the body portion 11a being closed by the pair of upper end plates 11b and lower end plates 11c.

[0052] The body portion 11a has a cylindrical shape. The intake pipe 12 is attached to the lower part of the body portion 11a of the casing 11. The upper end plate 11b and the lower end plate 11c each have a dish shape. The exhaust pipe 13 is attached to the upper part of the body portion 11a of the casing 11.

[0053] The compressor body 10 includes a compression mechanism 70 and a motor 80 inside the casing 11. The motor 80 rotates the shaft 81. The compression mechanism 70 compresses the refrigerant supplied from the suction pipe 12. The refrigerant compressed in the compression mechanism 70 is discharged to the outside of the compressor 1 through the exhaust pipe 13.

[0054] Motor 80 rotates shaft 81. Shaft 81 is connected to rollers 61 and 62, respectively. In the compression mechanism 70, shaft 81, rotated by motor 80, rotates rollers 61 and 62, respectively. Rollers 61 and 62 rotate eccentrically as shaft 81 rotates. As rollers 61 and 62 rotate, the refrigerant is compressed in the compression mechanism 70. The compression chamber is partitioned by vanes as rollers 61 and 62 rotate.

[0055] The shaft 81 has a passage through which lubricating oil flows. The shaft 81 has a communication hole that penetrates from the internal passage to the outside of the shaft 81 in order to supply lubricating oil to the lower bearing 31, cylinder 41, cylinder 42, and upper bearing 32, respectively.

[0056] The shaft 81 has a main shaft portion 82, an eccentric portion 83, an intermediate connecting portion 84, an eccentric portion 86, and a sub-shaft portion 87. In the shaft 81, the main shaft portion 82, the eccentric portion 83, the intermediate connecting portion 84, the eccentric portion 86, and the sub-shaft portion 87 are integrally formed. The shaft 81 rotates around the rotation axis 81a.

[0057] The main shaft portion 82 has a cylindrical or cylindrical shape. The upper end of the main shaft portion 82 is connected to the rotor of the motor 80. The lower end of the main shaft portion 82 is rotatably supported by the upper bearing 32. The lower end of the main shaft portion 82 forms a journal.

[0058] The eccentric portion 83 is a cylindrical part with a larger diameter than the main shaft portion 82. The central axis of the eccentric portion 83 is eccentric to the central axis of the main shaft portion 82. A roller 62 is attached to the eccentric portion 83.

[0059] The intermediate connecting section 84 connects the eccentric section 83 and the eccentric section 86.

[0060] The eccentric portion 86 is a cylindrical part with a larger diameter than the main shaft portion 82. The central axis of the eccentric portion 86 is eccentric from the central axis of the main shaft portion 82. The eccentric portion 86 is eccentric with respect to the central axis of the main shaft portion 82 on the opposite side from the eccentric portion 83. A roller 61 is attached to the eccentric portion 86. The lower surface of the eccentric portion 86 slides against the upper surface of the lower bearing 31.

[0061] The sub-shaft portion 87 has a cylindrical or cylindrical shape. The sub-shaft portion 87 is rotatably supported by the lower bearing 31. The sub-shaft portion 87 constitutes a journal.

[0062] The compression mechanism 70 comprises a lower bearing 31, a cylinder 41, a middle plate 33, a cylinder 42, an upper bearing 32, and a muffler 90. The lower bearing 31, cylinder 41, middle plate 33, cylinder 42, and upper bearing 32 are stacked from bottom to top. The muffler 90 is attached to the upper bearing 32. The compression mechanism 70 is fixed to the casing 11 at the upper bearing 32.

[0063] The upper bearing 32 is positioned above the cylinders 41 and 42, respectively. The lower bearing 31 is positioned below the cylinders 41 and 42, respectively. The shaft 81 passes through the lower bearing 31, cylinder 41, middle plate 33, cylinder 42, and upper bearing 32. The shaft 81 has communication holes that penetrate from an internal flow path to the outside of the shaft 81 in order to supply lubricating oil to the lower bearing 31, cylinder 41, cylinder 42, and upper bearing 32, respectively.

[0064] The compression mechanism 70 includes a roller 61 that rotates eccentrically by a shaft 81 in a cylinder chamber formed inside the cylinder 41. The lower surface of the roller 61 slides against the upper surface of the lower bearing 31. The upper surface of the roller 61 also slides against the lower surface of the middle plate 33.

[0065] Furthermore, the compression mechanism 70 includes a roller 62 that rotates eccentrically by a shaft 81 in a cylinder chamber formed inside the cylinder 42. The lower surface of the roller 62 slides against the upper surface of the middle plate 33. The upper surface of the roller 62 also slides against the lower surface of the upper bearing 32.

[0066] The mounting plate 14 is fixed to the outer circumferential surface 11cS of the lower end plate 11c. The mounting plate 14 has three mounting surfaces 14S on which the vibration-damping member 16 is positioned. The mounting surfaces 14S are inclined in the direction in which the rotation axis 81a extends, i.e., with respect to the Z-axis direction. The perpendicular lines L of the mounting surfaces 14S intersect the outer circumferential surface 11cS of the lower end plate 11c. The perpendicular lines L of the mounting surfaces 14S also intersect the rotation axis 81a. Furthermore, when viewed along the Z-axis direction, the mounting surfaces 14S are positioned on the circumference C of the shaft 81 centered on the rotation axis 81a. In addition, one of the mounting surfaces 14S is positioned in the direction of the accumulator 20 when viewed along the Z-axis direction.

[0067] The vibration-damping member 16 has a cylindrical shape. The shape of the vibration-damping member 16 is an example, and the shape of the vibration-damping member used in the compressor according to this embodiment may be changed as appropriate. The vibration-damping member 16 is attached to the mounting plate 14 by means of bolts or the like.

[0068] The vibration-damping member 16 may be made of rubber such as natural rubber, chloroprene rubber, or butyl rubber. The vibration-damping member 16 should preferably have a loss coefficient of 0.05 or higher.

[0069] Because the mounting surface 14S is inclined with respect to the Z-axis direction, horizontal vibrations can be damped by the vibration-damping member 16. Generally, vibration-damping members can significantly dampen vibrations in the compression direction, but their vibration-damping effect is small in the sliding direction. Therefore, if the surface to which the vibration-damping member is mounted is vertical, the effect of damping horizontal vibrations becomes small. Because the effect of damping horizontal vibrations is small, it was difficult to reduce horizontal vibrations. With the compressor 1, since the mounting surface 14S is inclined, horizontal vibrations can be damped.

[0070] The mounting surface 14S in the compressor 1 is an example of the first surface.

[0071] In the compressor according to the first embodiment, vibration damping members are attached to a first surface that is inclined with respect to the direction in which the shaft extends, thereby suppressing horizontal vibrations.

[0072] <Second Embodiment> A compressor according to the second embodiment will now be described. The compressor according to the second embodiment includes a vibration-damping member provided on the bottom surface of the casing. Figure 5 is a side view of compressor 2, which is an example of a compressor according to the second embodiment.

[0073] In compressor 2, in addition to the configuration of compressor 1, a vibration-damping member 116 is attached to the bottom of the casing 11. The vibration-damping member 116 is provided between the location where compressor 2 is installed and the casing 11. For example, if compressor 2 is attached to the bottom plate of an enclosure such as an outdoor unit, the vibration-damping member 116 is provided between the casing 11 and the bottom plate.

[0074] For example, the vibration damping member 116 may be made of rubber with different rigidity and damping properties than the vibration damping member 16. The vibration damping member 116 primarily dampens vibrations in the vertical direction (Z direction). By combining the vibration damping member 16 and the vibration damping member 116, the rigidity and damping in the horizontal and vertical directions can be designed individually. For example, this can be applied when the rigidity in the vertical direction is insufficient with existing rubber.

[0075] The compressor according to the second embodiment, in addition to the operation and effects of the compressor according to the first embodiment, can more flexibly change the vibration damping state in both the horizontal and vertical directions.

[0076] <Third Embodiment> A compressor according to the third embodiment will now be described. The compressor according to the third embodiment includes a conversion member connected to a vibration-damping member and a further vibration-damping member. Figure 6 is a side view of compressor 3, which is an example of a compressor according to the third embodiment.

[0077] The conversion member 217 is provided between the vibration-damping member 16 and the vibration-damping member 216. The conversion member 217 converts the difference in mounting angles between the vibration-damping member 16 and the vibration-damping member 216.

[0078] The compressor according to the third embodiment, in addition to the operation and effects of the compressor according to the first embodiment, can be installed on a horizontal surface. Furthermore, the compressor according to the third embodiment can provide even greater vibration isolation in the vertical direction.

[0079] <Fourth Embodiment> A compressor according to the fourth embodiment will now be described. In the compressor according to the fourth embodiment, the first surface overlaps with the piping connected to the casing when viewed along the first direction. Figure 7 is a perspective view of compressor 4, which is an example of a compressor according to the fourth embodiment. Figure 8 is a side view of compressor 4, which is an example of a compressor according to the fourth embodiment. Figure 9 is a plan view of compressor 4, which is an example of a compressor according to the fourth embodiment.

[0080] The compressor 4 is equipped with a mounting plate 314 in place of the mounting plate 14 of the compressor 1. One of the mounting surfaces 314S of the mounting plate 314 coincides with the exhaust pipe 13 when viewed along the Z-axis direction.

[0081] The compressor according to the fourth embodiment, in addition to the operation and effects of the compressor according to the first embodiment, can suppress the transmission of vibrations to the piping (exhaust pipe 13 in the example of compressor 4).

[0082] <Fifth Embodiment> A compressor according to the fifth embodiment will now be described. In the compressor according to the fifth embodiment, the first surface is above the bottom surface of the casing. Figure 10 is a side view of compressor 4, which is an example of a compressor according to the fifth embodiment.

[0083] The compressor 5 is equipped with a mounting plate 414 in place of the mounting plate 14 of the compressor 1. The mounting surface 414S of the mounting plate 414 is located above the bottom surface 11cb of the lower end plate 11c.

[0084] The compressor according to the fifth embodiment, in addition to the operation and effects of the compressor according to the first embodiment, can reduce the final height when installed, even if the height is increased by the vibration-damping member.

[0085] <Sixth Embodiment> A compressor according to the sixth embodiment will now be described. The compressor according to the sixth embodiment is provided with three or more first mounting plates. Figure 11 is a side view of compressor 6, which is an example of a compressor according to the sixth embodiment.

[0086] The compressor 6 has three mounting plates 514 in place of the mounting plate 14 of the compressor 1. The mounting surfaces 514S of the mounting plates 514 are inclined in the direction in which the rotation axis 81a extends, i.e., with respect to the Z-axis direction. Also, when viewed along the Z-axis direction, the mounting surfaces 514S are arranged on the circumference of a circle centered on the rotation axis 81a of the shaft 81, similar to the mounting plate 14.

[0087] The compressor according to the sixth embodiment, in addition to the operation and effects of the compressor according to the first embodiment, can have a mounting plate directly attached to the casing.

[0088] <Compressor Installation> Next, the installation of the compressor will be described. In the following description, as an example, the case in which the compressor is attached to the bottom plate of the outdoor unit housing of a refrigeration system will be described. Figure 12 is a diagram illustrating the installation of the compressor according to this embodiment. Figure 12 is a diagram schematically showing the installation using compressor 1, which is an example of a compressor according to the first embodiment, as an example.

[0089] Assume that the compressor 1 is installed on the bottom plate PLT of the outdoor unit. The compressor 1 is installed on the bottom plate PLT via a mounting plate 19. The mounting plate 19 has an inclined surface 19S that faces the mounting surface 14S. The inclined surface 19S is inclined with respect to the Z-axis direction. The vibration-damping member 16 is sandwiched between the mounting surface 14S and the inclined surface 19S.

[0090] Furthermore, the compressor may be installed by attaching it to the inclined bottom plate of the outdoor unit housing via a vibration-damping member. Figure 13 is a diagram illustrating the installation of the compressor according to this embodiment. Figure 13 is a diagram schematically showing the installation using compressor 1, which is an example of a compressor according to the first embodiment, as an example.

[0091] Assume that the compressor 1 is installed on the bottom plate PLT2 of the outdoor unit. The compressor 1 is installed on the bottom plate PLT2 via a vibration-damping member 16. The bottom plate PLT2 has an inclined surface S. The inclined surface S is inclined with respect to the Z-axis direction. The inclined surface S faces the mounting surface 14S. The vibration-damping member 16 is sandwiched between the mounting surface 14S and the inclined surface S.

[0092] <Refrigeration equipment> A refrigeration system equipped with a compressor according to this embodiment will now be described. Figure 14 is a schematic diagram of a refrigeration system 100, which is an example of a refrigeration system equipped with a compressor according to this embodiment.

[0093] The refrigeration system 100 includes a compressor 101, a four-way valve 102, a heat exchanger 103, an expansion valve 104, and a heat exchanger 105. The compressor 101 is the compressor according to this embodiment.

[0094] First, we will explain the case where the refrigeration system 100 is cooled by the heat exchanger 105. Figure 14 shows the connections when the refrigeration system 100 is cooled by the heat exchanger 105.

[0095] The refrigerant compressed by the compressor 101 is supplied to the heat exchanger 103 through the four-way valve 102. In the heat exchanger 103, the refrigerant supplied to the heat exchanger 103 is cooled by heat exchange with air or the like. The refrigerant cooled in the heat exchanger 103 condenses and liquefies, and is supplied to the expansion valve 104. The refrigerant is depressurized by the expansion valve 104. The depressurized refrigerant is supplied to the heat exchanger 105. In the heat exchanger 105, the refrigerant evaporates and vaporizes. The refrigerant discharged from the heat exchanger 105 then returns to the compressor 101 and is compressed again. In the heat exchanger 105, the refrigeration device 100 cools the object by the heat of vaporization caused by the evaporation of the refrigerant.

[0096] Next, we will explain the case where the refrigeration system 100 is heated by the heat exchanger 105. The refrigerant compressed by the compressor 101 is supplied to the heat exchanger 105 through the four-way valve 102. In the heat exchanger 105, the refrigeration system 100 heats the object by supplying the compressed, high-temperature refrigerant. The refrigerant that has undergone heat exchange in the heat exchanger 105 condenses and liquefies, and is supplied to the expansion valve 104. The refrigerant is depressurized by the expansion valve 104. The depressurized refrigerant is supplied to the heat exchanger 103. In the heat exchanger 103, the refrigerant evaporates and vaporizes by exchanging heat with air or the like. The refrigerant discharged from the heat exchanger 103 then passes through the four-way valve 102 and returns to the compressor 101 to be compressed again.

[0097] Although embodiments have been described above, it will be understood that various modifications to the form and details are possible without departing from the spirit and scope of the claims. Various modifications and improvements are possible, such as combinations or substitutions with parts or all of other embodiments. [Explanation of symbols]
