Description

[Technical field]

[0001] The present invention relates to a support structure for a compressor body and a liquid separator in a compressor, and more particularly to a compressor and a refrigeration and air-conditioning apparatus including the compressor. [Background technology]

[0002] In compressors used in air conditioners and the like, a liquid separator (also called an accumulator) is generally provided on the suction side of the compressor body to prevent liquid compression of the refrigerant. The liquid separator is fixed to the compressor body by, for example, joining members or piping fixed by welding. Therefore, the structure is such that vibrations from the compressor body are easily transmitted, and the liquid separator fixed to the compressor body vibrates significantly when the vibrations from the compressor body are transmitted, which causes an increase in noise. Therefore, a structure capable of suppressing the vibrations of the liquid separator is required.

[0003] Regarding vibration of a liquid separator (accumulator), International Publication No. 2023 / 282163 (Patent Document 1) is known. Patent Document 1 discloses a hermetic compressor including an accumulator container having a cup-shaped accumulator shell whose opening side is joined to a compressor main container, leg members fixed to the outer peripheral surface of the compressor main container housing and supporting the compressor main container and the accumulator container, and an elastic body supporting the leg members.

[0004] Furthermore, with regard to vibration of a liquid separator (accumulator), JP 2014-92078 A (Patent Document 2) discloses a compressor characterized in that it is provided with a secondary support member that supports the lower part of the accumulator with respect to an installation member on which the compressor body is installed.

[0005] However, the configuration disclosed in Patent Document 1 is unsatisfactory in that the compressor body and the liquid separator are integrated into one structure and therefore cannot be applied to a common rotary compressor structure in which the compressor body and the liquid separator are separate. While the configuration disclosed in Patent Document 2 can be applied to a structure in which the compressor body and the liquid separator are separate, the effect of suppressing vibration in the rotational direction around the compressor body is small and unsatisfactory because the structure supports the lower part of the liquid separator.

[0006] [Patent Document 1] International Publication No. 2023 / 282163 [Patent Document 2] JP 2014-92078 A Summary of the Invention [Problem to be solved by the invention]

[0007] The present disclosure has been made in consideration of the above points, and aims to provide a quieter compressor and a refrigeration and air conditioning equipment equipped with the compressor by suppressing vibration of the liquid separator alone and supporting rotational vibration around the compressor body. [Means for solving the problem]

[0008] In order to solve the above problems, the present disclosure provides a compressor including a compressor body and a liquid separator that is connected to the suction side of the compressor body and is separate from the compressor body, the compressor having the following features: The compressor includes three or more support parts that are attached to an installation surface on which the compressor is installed and are configured to support the compressor body, and at least one of the three or more support parts is attached to a side surface of the container of the liquid separator to support the liquid separator.

[0009] The present disclosure further provides a refrigeration and air conditioning apparatus including a compressor having the above-described configuration. Effect of the Invention

[0010] With the above configuration, it is possible to suppress vibration of the liquid separator alone and to support vibration in the rotational direction around the compressor body, thereby providing a quieter compressor and a refrigeration and air-conditioning equipment equipped with the compressor.

[0011] Other problems and solutions disclosed in the present application will be made clear in the section of the preferred embodiment and the drawings. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings, but the embodiment of the present invention is not limited to the specific embodiment described below. In the drawings, the same reference numerals indicate the same or corresponding parts.

[0014] The present disclosure is directed to a compressor and a refrigeration and air conditioning device including the compressor. A compressor according to an embodiment of the present invention includes a compressor body and a liquid separator that is separate from the compressor body and connected to the suction side of the compressor body. The compressor further includes three or more support parts that are attached to an installation surface on which the compressor is installed and configured to support the compressor body. The compressor according to an embodiment of the present invention is characterized in that at least one of the three or more support parts is attached to a container side surface of the liquid separator and supports the liquid separator.

[0015] With the above-mentioned configuration, vibration of the liquid separator alone is suppressed, and vibration in the rotational direction around the compressor body is supported, so that a higher noise reduction effect can be obtained. In addition, it is possible to provide a low-noise compressor in a structure in which the liquid separator is separate from the compressor body.

[0016] In a specific embodiment, the compressor further includes a joint member that joins the compressor body and the liquid separator. At least one of the three or more supports is fixed to a side surface of the container of the liquid separator and supports the liquid separator, thereby indirectly supporting the compressor body via the joint member.

[0017] In the specific embodiment, the at least one support preferably has an installation hole into which a member for fixing to an installation surface is inserted, and the installation hole is provided in the at least one support at a position directly below the center of the liquid separator. Three or more support parts of the compressor are provided with installation holes for fixing to the bottom surface of an apparatus housing (e.g., an outdoor unit housing of an air conditioner) via a member such as vibration isolator, and by adopting such a configuration, the weight of the compressor body allocated to the liquid separator can be supported from directly above the installation hole. This reduces the load on the support structure, making it possible to increase the reliability of the support structure.

[0018] In the above specific embodiment, preferably, at least one support part may have an L-shaped structure including a first plate part fixed to the vessel side surface of the liquid separator, and a second plate part connected to the first plate part, facing the installation surface, and having an installation hole. With such a configuration, it is possible to support the vessel side surface of the liquid separator with a simple structure.

[0019] In a preferred embodiment, the at least one support portion is fixed to a side surface of the container of the liquid separator and to a side surface of the housing of the compressor body, directly supporting the liquid separator and the compressor body. With this configuration, a joining member for joining the compressor body and the liquid separator is not required, which makes it possible to reduce costs.

[0020] In a specific embodiment, the liquid separator has a bottom located above the bottom of the compressor body, and the compressor body and the liquid separator may be connected by a pipe that runs from inside the liquid separator to the bottom of the liquid separator and enters the suction port of the compressor body. Also, in a specific embodiment, at least two other supports of the three or more supports may be fixed to the side of the housing of the compressor body to directly support the compressor body.

[0021] The above-mentioned configuration can be suitably applied to a compressor including a compressor body having a rotary compression mechanism. The above-mentioned configuration can be suitably applied to a compressor having a compressor body with a vertically-mounted structure.

[0022] In a specific embodiment, a refrigeration air conditioning device is provided that includes a compressor having the above configuration. The above configuration makes it possible to provide a refrigeration air conditioning device that produces less noise. The refrigeration air conditioning device may be an air conditioner that includes an indoor unit and an outdoor unit, in which case the outdoor unit may include a compressor having the above configuration. The above configuration makes it possible to provide an air conditioner that includes an outdoor unit that produces less noise.

[0023] Hereinafter, with reference to Figures 1 to 4, a compressor according to an embodiment of the present invention and, as an example of a refrigeration and air conditioning device equipped with a compressor, a compressor provided in an outdoor unit of an air conditioner, and an air conditioner including an indoor unit and an outdoor unit equipped with a compressor will be described as an example.

[0024] 1 to 4, a compressor for an air conditioner and an air conditioner 100 equipped with the compressor are described as an example of a compressor and a refrigeration air conditioner equipped with the compressor. Here, the refrigeration air conditioner is a general term for equipment that uses a refrigerant and a refrigeration cycle, such as an air conditioner (air conditioner), a refrigerator, and a freezer. More specifically, examples of the refrigeration air conditioner may include air conditioners such as packaged air conditioners and multi-air conditioners for buildings, heat source equipment such as freezers and chilling units, commercial freezers such as showcases, refrigerator-freezers, unit coolers, and ice makers, transportation refrigeration equipment such as car air conditioners, and heat pump water heaters.

[0025] First, the overall configuration of an air conditioner 100 as an example of a refrigeration and air conditioning device will be described below with reference to Fig. 1. Fig. 1 is a front view of an indoor unit, an outdoor unit, and a remote controller that constitute an air conditioner equipped with a compressor according to an embodiment of the present invention. The air conditioner 100 is a device that performs air conditioning (hereinafter also referred to as air conditioning) by circulating a refrigerant in a refrigeration cycle (heat pump cycle). As shown in Fig. 1, the air conditioner 100 comprises an indoor unit 10 installed indoors (air-conditioned space), an outdoor unit 30 installed outdoors, and a remote controller 40 operated by a user.

[0026] The indoor unit 10 includes a remote controller transmitting / receiving unit 10a. The remote controller transmitting / receiving unit 10a transmits and receives predetermined signals to and from a remote controller 40 by infrared communication or the like. For example, the remote controller transmitting / receiving unit 10a receives signals such as an operation command, a stop command, a command to change the set temperature, a command to change the operating state, and a command to set a timer from the remote controller 40. The remote controller transmitting / receiving unit 10a also transmits a detected value of the indoor temperature and the like to the remote controller 40.

[0027] Although not shown in FIG. 1, the indoor unit 10 and the outdoor unit 30 are connected via a refrigerant piping and also via a communication line.

[0028] Fig. 2 is an explanatory diagram showing a refrigerant circuit Q of an air conditioner 100 according to this embodiment. Note that solid arrows in Fig. 2 indicate the flow of refrigerant during heating operation. Also, dashed arrows in Fig. 2 indicate the flow of refrigerant during cooling operation. As shown in Fig. 2, the indoor unit 10 includes an indoor heat exchanger 12 and an indoor fan 14. The outdoor unit 30 includes a compressor 31 according to the embodiment of the present invention, an outdoor heat exchanger 32, an outdoor fan 33, an outdoor expansion valve 34, and a four-way valve 35.

[0029] The indoor heat exchanger 12 is a heat exchanger in which heat is exchanged between the refrigerant flowing through a heat transfer tube and the indoor air. The indoor fan 14 is, for example, a cylindrical cross-flow fan, and is driven by an indoor fan motor.

[0030] The compressor 31 is a device that compresses a low-temperature, low-pressure gas refrigerant by driving a compressor motor 31a, and discharges it as a high-temperature, high-pressure gas refrigerant. The compressor 31 will be described in detail later. The outdoor heat exchanger 32 is a heat exchanger in which heat exchange is performed between the refrigerant flowing through its heat transfer tube and the outside air sent in from the outdoor fan 33.

[0031] The outdoor fan 33 is a fan that sends outside air to the outdoor heat exchanger 32 by being driven by an outdoor fan motor 33a, and is installed near the outdoor heat exchanger 32. The outdoor expansion valve 34 has a function of reducing the pressure of the refrigerant condensed in the "condenser" (one of the outdoor heat exchanger 32 and the indoor heat exchanger 12). The refrigerant reduced in pressure in the outdoor expansion valve 34 is led to the "evaporator" (the other of the outdoor heat exchanger 32 and the indoor heat exchanger 12).

[0032] The four-way valve 35 is a valve that switches the flow path of the refrigerant depending on the operating state of the air conditioner 100. That is, during cooling operation (see the dashed arrow), the refrigerant circulates in a refrigeration cycle in a refrigerant circuit Q in which a compressor 31, an outdoor heat exchanger 32 (condenser), an outdoor expansion valve 34, and an indoor heat exchanger 12 (evaporator) are connected in sequence in a ring shape via the four-way valve 35.

[0033] During heating operation (see solid arrow), the refrigerant circulates in a refrigeration cycle in a refrigerant circuit Q in which a compressor 31, an indoor heat exchanger 12 (condenser), an outdoor expansion valve 34 and an outdoor heat exchanger 32 (evaporator) are connected in sequence in a ring shape via a four-way valve 35.

[0034] That is, in the refrigerant circuit Q in which the refrigerant circulates in a refrigeration cycle through the compressor 31, the “condenser”, the outdoor expansion valve 34 and the “evaporator”, one of the “condenser” and the “evaporator” is the outdoor heat exchanger 32, and the other is the indoor heat exchanger 12.

[0035] In the refrigerant circuit Q shown in FIG. 2, the compressor 31 is disposed in the outdoor unit 30. When liquid refrigerant that has not completely evaporated is sucked into the compressor, elements such as valves may be damaged by liquid compression. For this reason, the compressor 31 may be provided with a liquid separator (accumulator) on the suction side of the compressor body. The liquid separator is generally provided as a separate body, and is fixed to the compressor body by, for example, a joint member or piping fixed by welding or the like. For this reason, the structure is such that vibrations of the compressor body are easily transmitted, and the liquid separator fixed to the compressor body vibrates significantly due to the transmission of vibrations of the compressor body, which causes an increase in noise. For this reason, a structure capable of suppressing vibrations of the liquid separator is required.

[0036] Therefore, the compressor 31 according to the embodiment of the present invention has three or more support parts that are attached to the installation surface on which the compressor 31 is installed and are configured to support the compressor body, and at least one of the support parts is attached to the side surface of the container of the liquid separator to support the liquid separator. This suppresses vibration of the liquid separator alone and supports vibration in the rotational direction around the compressor body.

[0037] Fig. 3 is a diagram showing the connection and support structure of a compressor body and a liquid separator in a compressor 31 according to an embodiment of the present invention. Fig. 3(A) is a perspective view showing the connection and support structure of the compressor body and the liquid separator, and Fig. 3(B) is a top view showing the connection and support structure of the compressor body and the liquid separator.

[0038] As shown in FIG. 3, a compressor 31 according to the embodiment of the present invention includes a compressor body 50, a liquid separator 60, and a joining member 70 that joins the compressor body 50 and the liquid separator 60 together.

[0039] The compressor body 50 is composed of a vertically long cylindrical member, and has a housing 51 configured by closing the openings on both sides of the cylinder. A compressor motor and a compression mechanism are housed inside the housing 51 of the compressor body 50. The compression mechanism is rotationally driven by the compressor motor and compresses the refrigerant as the working fluid. The type of the compression mechanism of the compressor body 50 is not particularly limited, but may be a rotary type or scroll type compression mechanism. The compression mechanism and the compressor motor can be sources of vibration, and when one or both of the compressor motor and the compression mechanism are arranged below the compressor body 50, the vibration is particularly likely to be transmitted to the liquid separator 60.

[0040] The liquid separator 60 is connected to the suction side of the compressor body 50 and is configured as a separate body from the compressor body 50. The liquid separator 60 is a member having a function of separating the refrigerant liquid that has not been completely evaporated in the evaporator. An inlet pipe 65 that draws the refrigerant into the container 61 of the liquid separator 60 is provided at the upper end of the liquid separator 60. The outlet pipe 66 of the liquid separator 60 is provided at the bottom 60a, connected to the housing 51 of the compressor body 50, and connected to a suction side path provided in the compression mechanism inside the compressor body 50. In the embodiment to be described, the bottom 60a of the liquid separator 60 is located above the bottom 50a of the compressor body 50, and the compressor body 50 and the liquid separator 60 are connected by a pipe (outlet pipe 66) that exits from the inside of the container 61 of the liquid separator 60 at the bottom 61a of the container 61 of the liquid separator 60 and enters the suction port of the housing 51 of the compressor body 50. In this case, there is no need to connect an oil return pipe to the liquid separator 60.

[0041] The joining member 70 includes a fixing part 71 fixed to a side surface of the housing 51 of the compressor body 50, and a band 72 whose both ends are connected to the fixing part 71 and wrapped around the outer periphery of the container 61 of the liquid separator 60 to fasten and fix the liquid separator 60. The side surface of the housing 51 of the compressor body 50 and the fixing part 71 may be fixed by a fastening means such as a screw or a bolt, or may be fixed by welding. In the embodiment described below, the liquid separator 60 is fastened and fixed by the band 72, but the band 72 may be fixed by welding, or the housing 51 of the compressor body 50 and the container 61 of the liquid separator 60 may be fixed by any method.

[0042] The compressor 31 according to the embodiment of the present invention further includes a plurality of support parts, three support parts 52, 53, and 62 in the embodiment of Fig. 3, which are attached to an installation surface on which the compressor 31 is installed and configured to support the compressor body 50 and the liquid separator 60. In the embodiment described below, the compressor 31 will be described as including three support parts 52, 53, and 62, but in other embodiments, any number of support parts equal to or greater than four may be included.

[0043] Of the three support parts, two support parts 52, 53 are fixed to the side surface of the housing 51 of the compressor body 50 to directly support the compressor body 50. The support parts 52, 53 are preferably fixed to the side surface of the housing 51 of the compressor body 50 by welding. In the embodiment to be described, the two support parts 52, 53 are described as directly supporting the compressor body 50, but in other embodiments, three or more support parts may be configured to be fixed to the side surface of the housing 51 of the compressor body 50 to directly support the compressor body 50.

[0044] One of the three support parts, support part 62, is attached to the side surface of container 61 of liquid separator 60 to support liquid separator 60. In the embodiment shown in FIG. 3, support part 62 is fixed to the side surface of container 61 of liquid separator 60 to support liquid separator 60, thereby indirectly supporting compressor body 50 via joint member 70. Support part 62 is preferably fixed to the side surface of container 61 of liquid separator 60 by welding. In the embodiment to be described, one support part 62 is fixed to the side surface of container 61 of liquid separator 60, but in other embodiments, two or more support parts may be fixed to the side surface of container 61 of liquid separator 60 to indirectly support compressor body 50 via joint member 70.

[0045] The material of the supports 52, 53, 62 is not particularly limited, but is typically metal, and may be the same as or similar to the material of the compressor body 50 and / or the liquid separator 60.

[0046] The support portion 52 has a horizontal plate portion 52a fixed to the side surface of the housing 51 of the compressor body 50 at one edge, and the horizontal plate portion 52a has an installation hole 52b into which a member for fixing to the installation surface is inserted. Similarly, the support portion 53 has a horizontal plate portion 53a fixed to the side surface of the housing 51 of the compressor body 50 at one edge, and the horizontal plate portion 53a has an installation hole 53b into which a member for fixing to the installation surface is inserted. The horizontal plate portions 52a, 53a are welded to the side surface of the housing 51 of the compressor body 50 at one edge. Also, as illustrated in FIG. 3, the horizontal plate portions (surfaces) 52a, 53a may have their sides bent for reinforcement. In the embodiment to be described, the support portions 52, 53 have their installation holes 52b, 53b arranged around the cylindrical shape of the housing of the compressor body 50, shifted by approximately 120 degrees.

[0047] The support portion 62 has an L-shaped structure including a horizontal plate portion 62a facing the installation surface and a vertical plate portion 62b connected to the horizontal plate portion 62a and fixed to a side surface of the container 61 of the liquid separator 60. The vertical plate portion 62b is welded to the side surface of the container 61 of the liquid separator 60. As shown in FIG. 3, the horizontal plate portion 62a and the vertical plate portion 62b may have their sides bent for reinforcement. The horizontal plate portion 62a has an installation hole 62c into which a member for fixing to the installation surface is inserted. The installation hole 62c is provided at a position in the support portion 62 that is off center of the liquid separator 60, and is disposed around the cylindrical shape of the housing of the compressor main body 50, shifted by approximately 120 degrees from the installation holes 52b, 53b of the support portions 52, 53.

[0048] Fig. 4 is a diagram illustrating a state in which the compressor body 50 and the liquid separator 60 are supported on the bottom surface of the outdoor unit housing in the compressor 31 according to the embodiment of the present invention. Fig. 4(A) is a top view similar to Fig. 3(B), and Fig. 4(B) is a side view showing the structure of the lower part in which the compressor body 50 and the liquid separator 60 are supported on the bottom surface of the outdoor unit housing. In the side view of Fig. 4(B), elements arranged on the back side of the compressor body 50 are indicated by dashed lines.

[0049] 4, fixed feet 81, 82, 83 including anti-vibration rubber and the like are provided on the housing bottom surface 80 of the outdoor unit 30, and these are arranged around the center of the compressor body 50 with a deviation of approximately 120 degrees. Then, the upper parts of the fixed feet 81, 82, 83 are fitted into the installation holes 52b, 53b, 62c of the supports 52, 53, 62, respectively, and the compressor body 50 and the liquid separator 60 are arranged on the housing bottom surface 80 of the outdoor unit 30.

[0050] In the embodiment shown in Figures 3 and 4, the two support parts 52, 53 directly support the compressor body 50, and the support part 62 is fixed to the side of the container 61 of the liquid separator 60 and supports the liquid separator 60, thereby indirectly supporting the compressor body 50 via the connecting member 70, so that the compressor body 50 is supported at least at three points.

[0051] The compressor motor and compression mechanism inside the compressor body 50 are the source of vibration, and the vibration is transmitted through the joint member 70 and the piping 66 to the liquid separator 60. With this configuration, the support portion 62 suppresses the vibration of the liquid separator 60 alone, and since the support portion 62 supports the liquid separator 60 on the side surface of the liquid separator 60 instead of being connected below the liquid separator 60, it is possible to support the vibration in the rotational direction around the compressor body 50 and obtain a higher noise reduction effect. Furthermore, when the liquid separator 60 is structured separately from the compressor body 50, it is possible to suppress the vibration of the liquid separator 60, and it is possible to provide a low-noise compressor 31. This configuration is particularly effective for a compressor 31 equipped with a compressor body 50 having a rotary type or scroll type rotary compression mechanism, and is even more effective for a compressor 31 having a vertically-mounted compressor body 50.

[0052] Hereinafter, a compressor according to a modified embodiment will be described with reference to FIGS.

[0053] FIG. 5 is a diagram showing the connection and support structure of the compressor body 50 and the liquid separator 60 in the compressor 31A according to the first modified embodiment of the present invention. FIG. 5(A) is a perspective view showing the connection and support structure of the compressor body 50 and the liquid separator 60, and FIG. 5(B) is a top view showing the connection and support structure of the compressor body 50 and the liquid separator 60. The compressor 31A according to the first modified embodiment shown in FIG. 5 has a similar configuration to the compressor 31 according to the embodiment shown in FIG. 3 and FIG. 4 except for some parts, and the following description will focus on the differences. In addition, the same reference numerals are used to refer to the same elements as those of the compressor 31 according to the embodiment shown in FIG. 3 and FIG. 4.

[0054] As shown in FIG. 5, a compressor 31A according to a first modified embodiment of the present invention similarly includes a compressor body 50, a liquid separator 60, and a joining member .

[0055] The compressor 31A according to the embodiment of the present invention similarly includes a plurality of support parts, three support parts 52, 53, and 62A in the embodiment of Fig. 5, which are configured to be attached to an installation surface on which the compressor 31A is installed and to support the compressor body 50 and the liquid separator 60. In the embodiment to be described, the compressor 31A is described as including three support parts 52, 53, and 62A, but in other embodiments, any number of support parts equal to or greater than three may be included.

[0056] Of the three support parts, two support parts 52 and 53 are fixed to the side surface of the housing 51 of the compressor body 50 and directly support the compressor body 50. One support part 62A of the three support parts is also fixed to the side surface of the container 61 of the liquid separator 60 in the first modified embodiment shown in FIG. 5 and supports the liquid separator 60, thereby indirectly supporting the compressor body 50 via the joining member 70.

[0057] Similarly, the support portion 62A has an L-shaped structure including a horizontal plate portion 62a facing the installation surface and a vertical plate portion 62b connected to the horizontal plate portion 62a and fixed to a side surface of the container 61 of the liquid separator 60, but the orientation of the L-shape is different from that of the embodiment shown in Figs. 3 and 4. The horizontal plate portion 62a is inserted under the liquid separator 60, and an installation hole 62c of the horizontal plate portion 62a is provided at a position on the support portion 62 that is approximately directly below the center of the liquid separator 60. In the first modified embodiment shown in Fig. 5, the installation hole 62c is disposed toward the support portion 53 from a position approximately 120 degrees offset from the installation holes 52b, 53b of the support portions 52, 53 around the cylindrical shape of the housing of the compressor body 50. However, the arrangement is not limited to that shown in Figure 5, and the installation hole 62c of the support part 62A may be arranged at a position approximately 120 degrees offset from the installation holes 52b, 53b of the support parts 52, 53 around the cylindrical shape of the housing of the compressor main body 50.

[0058] In the first modified embodiment shown in Figure 5, the two support parts 52, 53 directly support the compressor body 50, and the support part 62A is fixed to the side of the container 61 of the liquid separator 60 to support the liquid separator 60, thereby indirectly supporting the compressor body 50 via the joining member 70, and thus the compressor body 50 is supported at least at three points.

[0059] With this configuration, the support portion 62 suppresses the vibration of the liquid separator 60 alone, and since the support portion 62 supports the liquid separator 60 on the side surface thereof rather than being connected below the liquid separator 60, it is possible to support the vibration in the rotational direction around the compressor body 50, thereby achieving a higher noise reduction effect. Furthermore, in a structure in which the liquid separator 60 is separate from the compressor body 50, it is possible to suppress the vibration of the liquid separator 60, and it is possible to provide a low-noise compressor 31A. Furthermore, in the embodiment of the first modification shown in FIG. 5, the installation hole 62c is provided at a position directly below the center of the liquid separator 60 in the support portion 62A, so that the weight of the compressor body 50 allocated to the liquid separator 60 can be supported from directly above the installation hole 62c. Therefore, it is possible to reduce the load on the support structure and increase the reliability of the support structure.

[0060] FIG. 6 is a diagram showing a support structure of the compressor body 50 and the liquid separator 60 in a compressor 31B according to a second modified embodiment of the present invention. FIG. 6(A) is a perspective view showing the support structure of the compressor body 50 and the liquid separator 60, and FIG. 6(B) is a top view showing the support structure of the compressor body 50 and the liquid separator 60. The compressor 31B according to the second modified embodiment shown in FIG. 6 has a similar configuration to the compressor 31 according to the embodiment shown in FIG. 3 and FIG. 4 except for some parts, and the following description will focus on the differences. Also, the same reference numerals will be used to describe the same elements as those of the compressor 31 according to the embodiment shown in FIG. 3 and FIG. 4.

[0061] As shown in FIG. 6, a compressor 31B according to a second modified embodiment of the present invention includes a compressor body 50 and a liquid separator 60, similar to the first modified embodiment, but does not include a joining member.

[0062] The compressor 31B according to the embodiment of the present invention similarly includes a plurality of support parts, three support parts 52, 53, 54B in the embodiment of Fig. 6, which are attached to an installation surface on which the compressor 31B is installed and configured to support the compressor body 50 and the liquid separator 60. In the embodiment to be described, the compressor 31B is described as including three support parts 52, 53, 54B, but in other embodiments, any number of support parts equal to or greater than three may be included.

[0063] Two of the above three support parts, support parts 52 and 53, are similarly fixed to side surfaces of the housing 51 of the compressor body 50 to directly support the compressor body 50. In the second modified embodiment, one of the above three support parts, support part 54B, is fixed to a side surface of the container 61 of the liquid separator 60 and is also fixed to a side surface of the housing 51 of the compressor body 50 to directly support both the liquid separator 60 and the compressor body 50.

[0064] Support part 54B has an L-shaped structure including horizontal plate part 54a, one edge of which is fixed to the side surface of housing 51 of compressor body 50 and facing the installation surface, and vertical plate part 54b, which is connected to horizontal plate part 54a and fixed to the side surface of container 61 of liquid separator 60. Horizontal plate part 54a has installation hole 54c into which a member for fixing to the installation surface is inserted, and installation hole 54c is provided at a position in support part 54B that is offset from the center of liquid separator 60, and is disposed around the cylindrical shape of the housing of compressor body 50, shifted by approximately 120 degrees from installation holes 52b, 53b of support parts 52, 53.

[0065] In the second modified embodiment shown in Figure 6, two support parts 52, 53 directly support the compressor body 50, and support part 54A directly supports the compressor body 50 together with the liquid separator 60, thereby directly supporting the compressor body 50 at at least three points.

[0066] With this configuration, the support portion 54 suppresses vibration of the liquid separator 60 alone, and since the support portion 54 supports the liquid separator 60 on the side surface thereof rather than being connected below the liquid separator 60, it is possible to support vibration in the rotational direction around the compressor body 50 and obtain a higher noise reduction effect. Furthermore, in a structure in which the liquid separator 60 is separate from the compressor body 50, it is possible to suppress vibration of the liquid separator 60, and it is possible to provide a low-noise compressor 31B. Furthermore, in the second modified embodiment shown in FIG. 6, the support portion 54A serves as a joining member that joins the liquid separator 60 and the compressor body 50, so that a separate joining member that joins the compressor body 50 and the liquid separator 60 is not required, and it is possible to reduce costs.

[0067] According to the embodiment described above, it is possible to provide a quieter compressor and a refrigeration and air conditioning equipment equipped with the compressor by suppressing vibration of the liquid separator alone and supporting rotational vibration around the compressor body.

[0068] The embodiments of the present invention are not limited to the above-described embodiments, and may include various modified examples. For example, the above-described embodiments have been described in detail for easy understanding, and are not necessarily limited to those including all of the configurations described. In addition, it is possible to replace a part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. In addition, it is possible to add, delete, or replace a part of the configuration of each embodiment with another configuration. [Explanation of symbols]
