Description
Technical Field
The utility model relates to an outdoor unit of air conditioner that has realized the reduction of noise.
Background
Conventionally, an outdoor unit of an air conditioner includes an outer casing and a partition plate partitioning the inside of the outer casing. Furthermore, a machine chamber is formed by a part of the outer contour and the partition. A compressor is housed in the machine chamber. When the compressor is driven, noise is generated from the compressor. Therefore, the conventional outdoor unit includes a sound insulating member surrounding an outer peripheral portion of the compressor. However, there is a case where noise leaks from the soundproof member surrounding the outer peripheral portion of the compressor. The noise leaking from the sound insulating member surrounding the outer periphery of the compressor is, for example, noise transmitted from the gap of the sound insulating member to the outside of the sound insulating member. Further, for example, the noise leaking from the sound insulating member surrounding the outer periphery of the compressor is noise generated when the compressor or a refrigerant pipe connected to the compressor comes into contact with the sound insulating member and vibration of the compressor is transmitted to the sound insulating member. Therefore, the following structure is also proposed: in an outdoor unit of a conventional air conditioner, a sound insulating member is provided in a portion constituting a machine room in a rear surface portion of an outer casing portion, thereby suppressing leakage of noise, which leaks from the sound insulating member surrounding an outer peripheral portion of a compressor, to the outside of the outdoor unit (see patent document 1).
Patent document 1: japanese laid-open patent publication No. 2012-197997
Noise leaking from the sound insulating member surrounding the outer periphery of the compressor is reflected by the partition plate constituting a part of the machine chamber, and propagates in a specific direction. In this case, the noise of the outdoor unit increases in the direction in which the noise reflected by the partition plate propagates. In order to suppress the noise, the direction in which the noise propagates needs to be dispersed. However, in the conventional outdoor unit in which the leakage of noise from the sound insulating member surrounding the outer periphery of the compressor to the outside of the outdoor unit is suppressed, the sound insulating member provided outside the sound insulating member surrounding the outer periphery of the compressor is provided on the rear surface portion of the outer casing portion. The sound insulating member provided on the rear surface of the outer shell is located at a position distant from a position where noise leaking from the sound insulating member surrounding the outer periphery of the compressor is reflected by the partition plate. Therefore, in the conventional outdoor unit in which the leakage of the noise from the sound insulating member surrounding the outer periphery of the compressor to the outside of the outdoor unit is suppressed, the noise reflected by the partition plate and propagated in the specific direction cannot be sufficiently dispersed by the sound insulating member provided on the rear surface of the outer casing. Therefore, the conventional outdoor unit, which suppresses the leakage of the noise leaking from the sound insulating member surrounding the outer periphery of the compressor to the outside of the outdoor unit, has a problem that the noise of the outdoor unit cannot be sufficiently suppressed when the noise leaks from the sound insulating member surrounding the outer periphery of the compressor.

The main body 41 is provided with a container 42 as a closed container. The compression mechanism is housed in the container 42. Further, the compressor 40 includes a suction muffler 43 as a closed container. The suction muffler 43 separates the refrigerant flowing into the suction muffler 43 into a gaseous refrigerant and a liquid refrigerant. The outlet of the refrigerant of suction muffler 43 is connected to the inlet of the refrigerant of main body 41. Then, the gaseous refrigerant is supplied from suction muffler 43 to main body portion 41. The gaseous refrigerant is compressed by the compression mechanism of the body 41 and discharged from the body 41. That is, the inlet of the refrigerant of the suction muffler 43 is the suction port of the refrigerant of the compressor 40. The outlet of the refrigerant of the body 41, in other words, the outlet of the refrigerant of the container 42 is a discharge port of the refrigerant of the compressor 40.

In other words, the four-way switching valve 11 switches the connection destination of the refrigerant suction port of the compressor 40 to the outdoor heat exchanger 12 or the indoor heat exchanger 13.
The outdoor heat exchanger 12 functions as an evaporator during the heating operation and functions as a condenser during the cooling operation. In embodiment 1, a fan 21 is provided in the vicinity of the outdoor heat exchanger 12. The fan 21 supplies outdoor air, which is a heat exchange target of the refrigerant flowing through the outdoor heat exchanger 12, to the outdoor heat exchanger 12. The fan 21 is driven by a motor 22. The indoor heat exchanger 13 functions as a condenser during the heating operation and functions as an evaporator during the cooling operation.

These indoor units 3 are connected in parallel to the outdoor unit 2.
Fig. 2 is a perspective view of the outdoor unit according to embodiment 1, as viewed from the front right side. Fig. 3 is a perspective view of the outdoor unit according to embodiment 1 as viewed from the front right side, and is a view of the outdoor unit with the top surface portion, the front surface portion, the left side surface portion, the right side surface portion, and the back surface portion of the outer shell portion removed.
The outdoor unit 2 includes, for example, a substantially rectangular parallelepiped outer shell portion 50. The outer frame portion 50 is provided with a plurality of grips 59 to be gripped by an operator when moving the outdoor unit 2. The configuration of the outline portion 50 is not particularly limited, but in embodiment 1, the outline portion 50 is configured by a top panel 51, a base 52, a front panel 53, a maintenance panel 54, a right side panel 55, a left side panel 56, a cover panel 57, and a cover panel 58.
The top panel 51 constitutes a top surface portion of the outline portion 50. The base 52 constitutes a bottom surface portion of the outline portion 50. The front panel 53 constitutes a left side portion of the front surface portion of the outline portion 50. The maintenance panel 54 constitutes an upper portion on the right side of the front surface portion of the housing 50 and an upper portion on the front side of the right side surface portion of the housing 50. Right side panel 55 constitutes an upper portion on the rear side of the right side surface of outer shell 50 and an upper portion on the right side of the rear surface of outer shell 50. The left side panel 56 constitutes a left side portion of the outer shell 50. Cover panel 57 constitutes a lower portion on the right side of the front surface portion of outline 50 and a lower portion on the front side of the right side surface portion of outline 50. Cover panel 58 constitutes a lower portion on the rear side of the right side surface portion of outline 50 and a lower portion on the right side of the back surface portion of outline 50.
The interior of the housing 50 is partitioned into a blower chamber 61 and a machine chamber 62 by a partition 60. That is, the machine room 62 is formed by a part of the outline 50 and the partition 60. The outdoor heat exchanger 12 is housed in the blower chamber 61. Although not shown in fig. 3, the fan 21 and the motor 22 are also housed in the blower chamber 61. In addition, the machine room 62 accommodates the compressor 40.
Conventionally, when an operation of an air conditioner is started and a compressor is driven, the compressor vibrates. In addition, noise may be generated by vibration of the compressor. Therefore, some conventional air conditioners include a sound insulating member surrounding an outer peripheral portion of a compressor. The air conditioner 1 according to embodiment 1 also includes a 1 st sound insulating member 70 surrounding the outer periphery of the compressor 40. The 1 st sound insulating member 70 has the same structure as a conventional sound insulating member. For example, the 1 st sound insulating member 70 is configured as follows.
Fig. 4 is a side view of the periphery of the compressor of the outdoor unit according to embodiment 1. In fig. 4, the 1 st soundproof member 70 is shown in cross section.
The compressor 40 is surrounded by the 1 st soundproof member 70 at the side and above. The 1 st sound insulating member 70 includes a rubber portion 71 formed of rubber and constituting an outer shell. That is, the rubber portion 71 has rigidity that can maintain the shape of the outline portion, and has sound insulation properties. The 1 st sound insulating member 70 is provided with a nonwoven fabric 72 on the inner peripheral surface of the rubber portion 71, in other words, on the surface of the rubber portion 71 facing the compressor 40. The nonwoven fabric 72 has a sound absorbing effect.
However, conventionally, noise may leak from a sound insulating member surrounding the outer periphery of the compressor. For example, noise of the compressor leaks from a gap of the sound insulating member surrounding the outer periphery of the compressor. Further, for example, the compressor or a refrigerant pipe connected to the compressor may come into contact with a sound insulating member surrounding an outer peripheral portion of the compressor, and vibration of the compressor may be transmitted to the sound insulating member. In this case, noise is generated due to vibration of the sound insulating member surrounding the outer peripheral portion, and the noise leaks from the sound insulating member surrounding the outer peripheral portion of the compressor. For example, the compressor or a refrigerant pipe connected to the compressor may come into contact with the sound insulating member surrounding the outer periphery of the compressor due to an assembly error of the sound insulating member surrounding the outer periphery of the compressor, an assembly error of the compressor, or the like. Further, for example, the compressor or a refrigerant pipe connected to the compressor may come into contact with the sound insulating member surrounding the outer periphery of the compressor due to deformation caused by aging or the like of the sound insulating member surrounding the outer periphery of the compressor. For example, when the compressor is inclined due to the refrigerant pipe being connected to the compressor, the compressor or the refrigerant pipe connected to the compressor may contact the sound insulating member surrounding the outer periphery of the compressor.
Therefore, the following structure is also proposed: in the conventional outdoor unit of an air conditioner, the sound insulating member is provided in a portion constituting the machine room in the rear surface portion of the outer casing portion, thereby suppressing leakage of noise, which leaks from the sound insulating member surrounding the outer peripheral portion of the compressor, to the outside of the outdoor unit.
Here, the noise leaking from the sound insulating member surrounding the outer periphery of the compressor is reflected by the partition plate constituting a part of the machine chamber, and propagates in a specific direction. In this case, the noise of the outdoor unit increases in the direction in which the noise reflected by the partition plate propagates. In order to suppress the noise, the direction in which the noise propagates needs to be dispersed. However, in the conventional outdoor unit in which the leakage of noise from the sound insulating member surrounding the outer periphery of the compressor to the outside of the outdoor unit is suppressed, the sound insulating member provided outside the sound insulating member surrounding the outer periphery of the compressor is provided on the rear surface portion of the outer casing portion. The sound insulating member provided on the rear surface of the outer shell is located at a position distant from a position where noise leaking from the sound insulating member surrounding the outer periphery of the compressor is reflected by the partition plate. Therefore, in the conventional outdoor unit in which the leakage of the noise from the sound insulating member surrounding the outer periphery of the compressor to the outside of the outdoor unit is suppressed, the noise reflected by the partition plate and propagated in the specific direction cannot be sufficiently dispersed by the sound insulating member provided on the rear surface portion of the outer casing portion. Therefore, in the case where noise leaks from the sound insulating member surrounding the outer periphery of the compressor, the conventional outdoor unit, which suppresses the leakage of the noise leaking from the sound insulating member surrounding the outer periphery of the compressor to the outside of the outdoor unit, cannot sufficiently suppress the noise of the outdoor unit.
Therefore, the outdoor unit 2 according to embodiment 1 includes the 2 nd sound insulating member 80 in the machine chamber 62.
Fig. 5 is a cross-sectional view of the machine chamber of the outdoor unit according to embodiment 1, as viewed from above. The lower side of the drawing sheet of fig. 5 is the front surface side of the outdoor unit 2. In other words, fig. 5 is a top view of the interior of the machine chamber 62. In the description of the 2 nd soundproof member 80, the 1 st front surface portion 63, the 1 st side surface portion 64, and the 1 st back surface portion 65 are defined as follows. In the outline portion 50, a portion constituting a front surface portion of the machine chamber 62 is referred to as a 1 st front surface portion 63. In the housing 50, a portion constituting a side surface portion of the machine room 62 is referred to as a 1 st side surface portion 64. In the outer shell 50, a portion constituting the rear surface of the machine chamber 62 is referred to as a 1 st rear surface portion 65.
The 2 nd soundproof member 80 is a plate-like member extending in the up-down direction. Further, the 2 nd soundproof member 80 has a nonwoven fabric 84 on the surface on the compressor 40 side. In other words, the 2 nd sound insulating member 80 is provided with the nonwoven fabric 84 on the surface on the 1 st sound insulating member 70 side. The 2 nd sound insulating member 80 is disposed in a space surrounded by the partition 60, the 1 st sound insulating member 70, the 1 st front surface portion 63, the 1 st side surface portion 64, and the 1 st back surface portion 65 so as not to contact the 1 st sound insulating member 70, the 1 st front surface portion 63, the 1 st side surface portion 64, and the 1 st back surface portion 65.
In embodiment 1, the 2 nd sound insulating member 80 includes the 1 st sound insulating part 81 and the 2 nd sound insulating part 82. The 1 st sound insulating portion 81 is disposed between the 1 st sound insulating member 70 and the 1 st back surface portion 65. The end of the 1 st sound insulating part 81 on the side of the partition plate 60 is disposed in the vicinity of the partition plate 60. At this time, the end of the 1 st sound insulating part 81 on the side of the partition 60 may or may not contact the partition 60. However, the end of the 1 st sound insulating portion 81 on the side of the partition 60 is in contact with the partition 60, and compared with the case where the end is in contact with the partition 60, the transmission of noise to the 1 st rear surface portion 65 side through the space between the 1 st sound insulating portion 81 and the partition 60 is suppressed, and the sound insulating effect of the outdoor unit 2 is improved. The 2 nd sound insulating part 82 is disposed between the 1 st sound insulating member 70 and the 1 st side surface part 64. In embodiment 1, the end portion of the 1 st sound insulating part 81 on the 2 nd sound insulating part 82 side is connected to the end portion of the 2 nd sound insulating part 82 on the 1 st sound insulating part 81 side. That is, in embodiment 1, the 2 nd sound insulating member 80 has a substantially L-shape in plan view. In the compressor 40 according to embodiment 1, the main body portion 41 is disposed closer to the partition 60 than the suction muffler 43.
As shown in fig. 5, the noise leaking from the 1 st soundproof member 70 surrounding the outer circumferential portion of the compressor 40 is reflected at the position a of the partition 60 and propagates in a specific direction indicated by a dotted arrow. This noise is dispersed in the direction of the noise in the process of being reflected by the 1 st sound insulating member 70 and the 1 st sound insulating portion 81 of the 1 st sound insulating member 70 and the 2 nd sound insulating member 80 between the 1 st sound insulating portion 81 and the 1 st sound insulating member 70. In addition, the noise is absorbed by the nonwoven fabric 84 on the surface of the 1 st sound insulating part 81 in the process of being reflected by the 1 st sound insulating member 70 and the 1 st sound insulating part 81. In addition, the noise is attenuated during the reflection by the 1 st sound insulating member 70 and the 1 st sound insulating member 70. In this way, since the outdoor unit 2 according to embodiment 1 includes the 1 st sound insulating part 81 of the 2 nd sound insulating member 80, it is possible to suppress the leakage of the noise leaking from the 1 st sound insulating member 70 to the outside of the outdoor unit 2, and it is possible to suppress the noise of the outdoor unit 2 more than before.
When the noise leaking from the 1 st sound insulating member 70 surrounding the outer peripheral portion of the compressor 40 is reflected by the partition 60 and directed toward the 2 nd sound insulating portion 82 of the 2 nd sound insulating member 80, the noise is reflected by the 1 st sound insulating member 70 and the 2 nd sound insulating portion 82 between the 1 st sound insulating member 70 and the 2 nd sound insulating portion 82 of the 2 nd sound insulating member 80. In addition, this noise is dispersed in the direction during the reflection by the 1 st sound insulating member 70 and the 2 nd sound insulating part 82. In addition, the noise is absorbed by the nonwoven fabric 84 on the surface of the 2 nd sound insulating part 82 in the process of being reflected by the 1 st sound insulating member 70 and the 2 nd sound insulating part 82. In addition, the noise is attenuated in the process of being reflected by the 1 st sound insulating member 70 and the 2 nd sound insulating portion 82. In this way, since the outdoor unit 2 according to embodiment 1 includes the 2 nd sound insulating portion 82 of the 2 nd sound insulating member 80, it is possible to suppress the leakage of the noise leaking from the 1 st sound insulating member 70 to the outside of the outdoor unit 2, and it is possible to suppress the noise of the outdoor unit 2 more than before.
Further, the 1 st sound insulating portion 81 disposed between the 1 st sound insulating member 70 and the 1 st back surface portion 65 can absorb and suppress the noise leaking from the 1 st sound insulating member 70 toward the 1 st back surface portion 65. In this case, the 1 st sound insulating portion 81 is disposed closer to the 1 st sound insulating member 70 than the conventional sound insulating member is, in comparison with the conventional sound insulating member provided in the rear surface portion of the outer shell portion, and therefore, the sound insulating effect equivalent to that of the conventional sound insulating member can be obtained with a smaller size than the conventional sound insulating member. That is, the 1 st sound insulating part 81 can obtain a sound insulating effect equivalent to that of the conventional sound insulating member at a lower cost than the conventional sound insulating member.
The 2 nd sound insulating portion 82 disposed between the 1 st sound insulating member 70 and the 1 st side surface portion 64 can also absorb and suppress noise leaking from the 1 st sound insulating member 70 toward the 1 st side surface portion 64.
Further, it is preferable that: the length of the 1 st sound insulating portion 81 in the longitudinal direction is longer than the length of the 1 st sound insulating member 70 in the longitudinal direction of the 1 st sound insulating portion 81 in a plan view. This is because the noise reflected by the 1 st sound insulating member 70 and the 1 st sound insulating portion 81 can be further suppressed when the space between the 1 st sound insulating member 70 and the 1 st sound insulating portion 81 is long in the longitudinal direction of the 1 st sound insulating portion 81. This is because the noise leaking from the 1 st sound insulating member 70 toward the 1 st back surface portion 65 can be absorbed more reliably. In addition, it is preferable that: in a plan view, the length of the 2 nd sound insulating part 82 in the longitudinal direction is longer than the length of the 1 st sound insulating member 70 in the longitudinal direction of the 2 nd sound insulating part 82. This is because the noise reflected by the 1 st sound insulating member 70 and the 2 nd sound insulating portion 82 can be further suppressed when the space between the 1 st sound insulating member 70 and the 2 nd sound insulating portion 82 is long in the longitudinal direction of the 2 nd sound insulating portion 82. This is because the noise leaking from the 1 st sound insulating member 70 toward the 1 st side surface portion 64 can be absorbed more reliably.
Further, although the 2 nd sound insulating member 80 according to embodiment 1 includes the 1 st sound insulating part 81 and the 2 nd sound insulating part 82, the 2 nd sound insulating member 80 may include only one of the 1 st sound insulating part 81 and the 2 nd sound insulating part 82. As described above, even if one of the 1 st sound insulating part 81 and the 2 nd sound insulating part 82 is used, the noise of the outdoor unit 2 can be suppressed more than before.
As described above, the outdoor unit 2 of the air conditioner 1 according to embodiment 1 includes the outer casing 50, the partition plate 60 partitioning the inside of the outer casing 50, the compressor 40, and the 1 st sound insulating member 70 surrounding the outer peripheral portion of the compressor 40. A machine chamber 62 is formed by a part of the outer shell 50 and the partition plate 60, and the compressor 40 is housed in the machine chamber 62. The outdoor unit 2 according to embodiment 1 further includes a plate-like 2 nd sound insulating member 80 extending in the vertical direction in the machine room 62. The 2 nd soundproof member 80 has a nonwoven fabric 84 on the surface on the compressor 40 side. The 2 nd sound insulating member 80 is disposed in a space surrounded by the partition 60, the 1 st sound insulating member 70, the 1 st front surface portion 63, the 1 st side surface portion 64, and the 1 st back surface portion 65 so as not to contact the 1 st sound insulating member 70, the 1 st front surface portion 63, the 1 st side surface portion 64, and the 1 st back surface portion 65.
In the outdoor unit 2 according to embodiment 1, the 2 nd sound insulating member 80 provided outside the 1 st sound insulating member 70 surrounding the outer periphery of the compressor 40 is disposed at a position closer to the position where the noise leaking from the 1 st sound insulating member 70 is reflected by the partition plate 60 than the conventional sound insulating member provided outside the sound insulating member surrounding the outer periphery of the compressor. Therefore, the outdoor unit 2 according to embodiment 1 can disperse the noise reflected by the partition 60 and propagated in a specific direction by the 2 nd sound insulating member 80. Therefore, the outdoor unit 2 according to embodiment 1 can suppress noise of the outdoor unit 2 more than ever.
Embodiment mode 2
The outdoor unit 2 may include a 3 rd sound insulating member 90 described later in the machine room. Note that in embodiment 2, items not described in particular are the same as those in embodiment 1, and the same functions and configurations as those in embodiment 1 are described using the same reference numerals.
Fig. 6 is a cross-sectional view of the machine chamber of the outdoor unit according to embodiment 2, as viewed from above.
The outdoor unit 2 according to embodiment 2 includes a 3 rd sound insulating member 90 in the machine chamber 62. The 3 rd sound insulating member 90 is a plate-like member extending in the up-down direction. The 3 rd sound insulating member 90 has a nonwoven fabric 91 on the surface on the compressor 40 side. In other words, the 3 rd sound insulating member 90 is provided with the nonwoven fabric 91 on the surface on the 1 st sound insulating member 70 side.
As shown in fig. 6, the 3 rd sound insulating member 90 is disposed between the spacer 60 and the 1 st sound insulating member 70. The 3 rd sound insulating member 90 is fixed to the spacer 60 by, for example, adhesion or the like. By providing the 3 rd sound insulating member 90, noise passing between the partition 60 and the 1 st sound insulating member 70 and heading toward the 1 st front surface portion 63 can be absorbed, and noise of the outdoor unit 2 can be further suppressed as compared with the outdoor unit 2 shown in embodiment 1.
In the outdoor unit 2 according to embodiment 2, the 3 rd sound insulating member 90 is also provided between the 1 st sound insulating member 70, the 2 nd sound insulating portion 82 of the 2 nd sound insulating member 80, and the 1 st front surface portion 63. The 3 rd sound insulating member 90 is fixed to the 2 nd sound insulating portion 82 of the 2 nd sound insulating member 80 by, for example, adhesion or the like. By providing the 3 rd sound insulating member 90, the noise passing through between the 1 st sound insulating member 70 and the 2 nd sound insulating part 82 and heading toward the 1 st front surface part 63 can be absorbed, and the noise of the outdoor unit 2 can be further suppressed as compared with the outdoor unit 2 shown in embodiment 1.
In embodiment 2, two third sound insulating members 90 are provided in the machine chamber 62, but noise of the outdoor unit 2 can be further suppressed than in the outdoor unit 2 shown in embodiment 1 only by providing any one third sound insulating member 90 in the machine chamber 62.
In embodiment 3, an example of a method of fixing the 2 nd sound insulating member 80 will be described. In embodiment 3, an example of the shape of the 2 nd sound insulating member 80 in the case where the refrigerant pipe is present at the location where the 2 nd sound insulating member 80 is disposed will be described. Note that in embodiment 3, items not described in particular are the same as those in embodiment 1 or embodiment 2, and the same functions and configurations as those in embodiment 1 or embodiment 2 are described using the same reference numerals.
Fig. 7 is a side view of the 2 nd sound insulating member according to embodiment 3.
The 2 nd sound insulating member 80 according to embodiment 3 includes at least one fixing portion 85 fixed to the partition 60 at an end portion on the partition 60 side. The fixing method of the fixing portion 85 and the partition 60 is not particularly limited. For example, the fixing portion 85 may be fixed to the partition 60 by screwing. For example, the following may be configured: a convex portion is provided on one of the fixing portion 85 and the separator 60, a concave portion into which the convex portion is hooked is provided on the other of the fixing portion 85 and the separator 60, and the fixing portion 85 and the separator 60 are fixed by hooking the convex portion into the concave portion.
In this way, by providing fixing portion 85 in second sound insulating member 80, second sound insulating member 80 can be easily arranged at a desired position. Further, by providing the fixing portion 85, the end portion of the 2 nd sound insulating member 80 on the side of the partition 60 can be disposed in the vicinity of the partition 60. Therefore, the noise can be suppressed from passing between the 1 st sound insulating portion 81 and the partition 60 and being transmitted to the 1 st rear surface portion 65 side, and the sound insulating effect of the outdoor unit 2 can be improved.
In the machine chamber 62 of the outdoor unit 2 according to embodiment 3, the refrigerant pipe 20 is provided at a position where the 2 nd sound insulating member 80 is disposed. Therefore, the 2 nd sound insulating member 80 is formed with a notch 86 and a notch 87 that open downward and into which the refrigerant pipe 20 is inserted. Since the notches 86 and 87 are opened downward, the 2 nd sound insulating member 80 can be easily installed even when the refrigerant pipe 20 is present by lowering the 2 nd sound insulating member 80 from above the refrigerant pipe 20 to the installation position.
The lateral width of the notch 87 at a position below the refrigerant pipe 20 is smaller than the lateral width at a height where the refrigerant pipe 20 is located. By forming the notches 87 in the 2 nd sound insulating member 80, it is possible to reduce the number of portions where the 2 nd sound insulating member 80 is not provided, and to suppress a decrease in the sound insulating effect due to the formation of the notches.
Embodiment 4
In embodiment 4, a specific example of the structure of the 2 nd soundproof member 80 will be described. Note that, in embodiment 4, items not described in particular are the same as those in any of embodiments 1 to 3, and the same functions and configurations as those in any of embodiments 1 to 3 are described using the same reference numerals.
Fig. 8 is a longitudinal sectional view of a 2 nd soundproof member according to embodiment 4.
The 2 nd sound insulating member 80 according to embodiment 4 includes a support member 88 having higher rigidity than the nonwoven fabric 84. The support member 88 is formed of, for example, rubber. The nonwoven fabric 84 is provided on the surface of the support member 88. In fig. 8, the nonwoven fabric 84 is provided on both surfaces of the support member 88, but the nonwoven fabric 84 may be provided at least on the surface on the compressor 40 side.
By configuring the 2 nd sound insulating member 80 in this manner, the 2 nd sound insulating member 80 can be prevented from falling down due to its own weight.
