Description

  The present invention relates to a compressor-mounted unit.

  Conventionally, as a compressor-mounted unit, there has been one disclosed in JP 2012-107563 A (Patent Document 1). In this compressor-mounted unit, the compressor is disposed in the housing, and one end of the refrigerant pipe is connected to the compressor. A portion between one end and the other end of the refrigerant pipe, that is, an intermediate portion is located above the bottom of the housing at a predetermined distance from the bottom of the housing, and is connected to the bottom of the housing via a vibration absorber. . Thereby, since the said vibration absorption material can absorb the vibration of refrigerant | coolant piping, the vibration damping effect of refrigerant | coolant piping is acquired.

JP 2012-107563 A

  By the way, in the said conventional compressor mounting unit, an adhesive material is used for the connection of the bottom part of a housing and a vibration-absorbing material. For this reason, the adhesive force of the adhesive material becomes weak due to deterioration over time, and the vibration absorbing material may come off from the bottom of the housing. When the vibration absorber is detached from the bottom of the housing, it only vibrates with the refrigerant pipe, making it difficult to absorb the vibration of the refrigerant pipe.

  That is, the conventional compressor-mounted unit has a problem that the vibration damping effect of the refrigerant pipe may be reduced due to deterioration over time.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a compressor-mounted unit that can prevent the vibration damping effect of piping from becoming small due to deterioration over time.

In order to solve the above problems, the compressor-mounted unit of the present invention is
The body,
A compressor disposed in the housing;
A pipe disposed in the housing and connected to the compressor;
A vibration absorbing material having a first end attached to a part of the pipe and a second end located on the opposite side of the first end;
The second end portion extends along one surface of the surface of the metal member fixed to the housing and the surface of the metal portion which is a part of the housing, and is formed on the one surface. Attached and in surface contact, a magnetized magnetic body is embedded.

  According to the said structure, the 1st end part of the said vibration-absorbing material is attached to a part of piping. On the other hand, the second end portion of the vibration absorbing material is located on the opposite side of the first end portion, and includes a surface of the metal member fixed to the housing and a surface of the metal portion that is a part of the housing. It extends along one surface and is attached to one surface. Thereby, the vibration absorbing material can absorb the vibration of the pipe.

  In addition, since the second end portion of the vibration absorber is in surface contact with one of the surface of the metal member fixed to the housing and the surface of the metal portion which is a part of the housing, the vibration absorber Can effectively transmit the vibration of the pipe to a metal member fixed to the casing or a metal portion which is a part of the casing. Therefore, the vibration of the piping can be sufficiently damped.

  In addition, since the magnetized magnetic body is embedded in the second end portion of the vibration absorber, the surface contact between the second end portion of the vibration absorber and the metal member or the metal portion can be maintained semipermanently. . Therefore, it is possible to prevent the vibration damping effect of the pipe from becoming small due to deterioration over time.

The compressor mounted unit of one embodiment is
A movement restricting portion for restricting movement of the second end portion in a direction parallel to the one surface;

  According to the said embodiment, it can prevent that the 2nd end part of a vibration absorber contacts the unintended location by the regulation of the said movement control part, and the vibration of piping will propagate to the said location.

In the compressor-mounted unit of one embodiment,
The movement restricting portion is a rib provided on the one surface.

  According to the embodiment, since the rib is provided on the surface of the metal member or the metal part, the strength of the metal member or the metal part can be increased.

In the compressor-mounted unit of one embodiment,
The magnetic body is a magnetized magnetic powder.

  According to the embodiment, the magnetic powder can be embedded in the second end portion of the vibration absorbing material without greatly reducing the density of the vibration absorbing material. Therefore, it is possible to prevent the vibration transmission function of the vibration absorbing material from being lowered.

In the compressor-mounted unit of one embodiment,
The content of the magnetic powder at the second end of the vibration absorbing material is greater than the content of the magnetic powder at a portion other than the second end of the vibration absorbing material.

  According to the embodiment, the content of the magnetic powder in the portion other than the second end portion of the vibration absorbing material can be reduced, so that the material cost can be reduced.

  As is clear from the above, the compressor-mounted unit of the present invention can prevent the vibration damping effect of the piping from becoming small due to deterioration over time.

[First Embodiment]
(1) Configuration of Air Conditioner FIG. 1 is a schematic perspective view for explaining the configuration of an air conditioner.

  The air conditioner 10 includes an indoor unit 20 attached to an indoor wall surface and the like, and an outdoor unit 30 installed outside the room. The indoor unit 20 and the outdoor unit 30 are connected to each other via a collective communication pipe 11 that collects refrigerant pipes, transmission lines, communication lines, and the like. The outdoor unit 30 is an example of a compressor-mounted unit.

(2) Refrigerant circuit of air conditioner FIG. 2 is a schematic refrigerant circuit diagram of the air conditioner.

  As shown in FIGS. 1 and 2, the indoor unit 20 is provided with an indoor heat exchanger 21, a blower fan 22, and the like, which are accommodated in a casing 23. On the other hand, the outdoor unit 30 includes a compressor 31, a four-way switching valve 32, an accumulator 33, an outdoor heat exchanger 34, an electric expansion valve 35, a filter 36, a first closing valve 37, a second closing valve 38, and a blower fan 39. Etc. are provided, and these are accommodated in the casing 40. The casing 40 is an example of a housing.

  The collective communication pipe 11 has refrigerant pipes 12 and 13. One entrance / exit of the indoor heat exchanger 21 of the indoor unit 20 is connected to the first closing valve 37 of the outdoor unit 30 via the refrigerant pipe 12. The other entrance / exit of the indoor heat exchanger 21 is connected to the second closing valve 38 of the outdoor unit 30 via the refrigerant pipe 13. A filter 36, an electric expansion valve 35, and a refrigerant pipe inside the outdoor unit 30 are provided between the first closing valve 37 and one entrance / exit of the outdoor heat exchanger 34. The other entrance / exit of the outdoor heat exchanger 34 is connected to a second port of the four-way switching valve 32 via a refrigerant pipe inside the outdoor unit 30. The fourth port of the four-way switching valve 32 is connected to the second closing valve 38 via the refrigerant pipe inside the outdoor unit 30.

  The four-way selector valve 32 has first and third ports in addition to the second and fourth ports. The first port of the four-way switching valve 32 is connected to the discharge port of the compressor 31 via the refrigerant pipe 41. On the other hand, the third port of the four-way switching valve 32 is connected to the inlet of the accumulator 33 via the refrigerant pipe 43. The outlet of the accumulator 33 is connected to the suction port of the compressor 31 via the refrigerant pipe 42. The refrigerant pipe 43 is an example of a pipe.

  Further, in the four-way switching valve 32, during the cooling operation, as indicated by the solid line arrow, the refrigerant flows from the first port to the second port and the refrigerant flows from the fourth port to the third port. At this time, as indicated by a dotted arrow, the refrigerant flows from the first port to the fourth port, and the refrigerant flows from the second port to the third port. Such switching of the refrigerant flow is controlled by a valve body (not shown) in the four-way switching valve 32.

  As described above, the refrigerant circuit is configured by connecting the indoor unit 20 and the outdoor unit 30 to each other by the refrigerant pipes 12 and 13 of the collective connection pipe 11. In this refrigerant circuit, during the cooling operation, the refrigerant discharged from the compressor 31 includes a four-way switching valve 32, an outdoor heat exchanger 34, an electric expansion valve 35, a filter 36, a first closing valve 37, an indoor heat exchanger 21, The second closing valve 38, the four-way switching valve 32 and the accumulator 33 are circulated so as to return to the compressor 31 again after flowing in this order. On the other hand, in the refrigerant circuit, during the heating operation, the refrigerant discharged from the compressor 31 is the four-way switching valve 32, the second closing valve 38, the indoor heat exchanger 21, the first closing valve 37, the filter 36, the electric expansion valve. 35, the outdoor heat exchanger 34, the four-way switching valve 32, and the accumulator 33 are circulated so as to return to the compressor 31 after flowing in this order.

(3) Configuration of Outdoor Unit 30 FIG. 3 is an exploded perspective view of the outdoor unit 30. In FIG. 3, the description of parts that are not very important for the description of the first embodiment is partially omitted.

  The casing 40 (shown in FIG. 1) of the outdoor unit 30 includes a bottom plate 51, a front plate 53, a left side plate 54, a right side plate 55, a closing valve cover 56, and a top plate 57. The compressor 31 is accommodated in a space surrounded by the bottom plate 51, the front plate 53, the left side plate 54, the right side plate 55, the closing valve cover 56 and the top plate 57. Here, the bottom plate 51, the left side plate 54, the right side plate 55, and the top plate 57 are formed by molding a sheet metal. The bottom plate 51 is an example of a metal part.

  The compressor 31 is attached to an attachment bolt 51 a of the bottom plate 51 via a vibration isolating rubber 61. Therefore, the vibration of the compressor 31 is absorbed by the anti-vibration rubber 61 and the vibration is difficult to be transmitted to the bottom plate 51, and the bottom plate 51 becomes a stationary member for the compressor 31. On the other hand, an accumulator 33 is attached to the compressor 31, and the accumulator 33 is integrated with the compressor 31. Therefore, the accumulator 33 becomes a member that vibrates together with the compressor 31.

  The refrigerant pipe 41 on the discharge side of the compressor 31 has a straight pipe part 41a that is relatively long and straight and a curved part 41b that is curved in a U-shape before being connected to the four-way switching valve 32. doing. Similarly to the refrigerant pipe 41, the refrigerant pipe 43 on the upstream side of the accumulator 33 is also curved in a U-shape with a straight pipe portion 43a that extends relatively long and straight before being connected to the four-way switching valve 32. And a curved portion 43b. The straight pipe portions 41a, 43a of the refrigerant pipes 41, 43 and the U-shaped curved portions 41b, 43b are suspended.

  Between the four-way switching valve 32 and the compressor 31, relatively long refrigerant pipes 41 and 43 are used without using a relatively short refrigerant pipe. The reason for this is that the refrigerant pipes 41 and 43 are damaged by the vibration of the compressor 31 or the vibration of the accumulator 33 that vibrates integrally with the compressor 31, the connection part of the refrigerant pipes 41 and 43 is disconnected, This is to suppress the occurrence of problems such as failure of the path switching valve 32. Because of such a structure, the refrigerant pipes 41 and 43 may resonate according to the operating frequency of the compressor 31 and vibrate relatively large. In order to prevent this vibration, a part of the vibration absorbing material 70 for absorbing vibration is wound around the curved portion 43 b of the refrigerant pipe 43.

  The first and second closing valves 37 and 38 are attached to the right side plate 55. At this time, since the first and second closing valves 37 and 38 are exposed from the opening of the right side plate 55, the closing valve cover 56 is attached to the outer surface of the right side plate 55 so as to cover the first and second closing valves 37 and 38. It is done.

  The first closing valve 37 is connected to the outdoor heat exchanger 34 via an electric expansion valve 35 (shown in FIG. 2) and the like. Since the outdoor heat exchanger 34 is disposed on the back side and the left side of the outdoor unit 30, it has a substantially L-shaped structure in plan view. The outdoor heat exchanger 34 is fixed to the bottom plate 51 by a tube plate 58. The tube plate 58 is fixed to the bottom plate 51 with screws or the like. The left side surface of the outdoor heat exchanger 34 is fixed to the bottom plate 51 along the left side plate 54 and is protected by the left side plate 54.

  A blower fan 39 is disposed in front of the outdoor heat exchanger 34. The blower fan 39 is attached to the fan motor 62, and the fan motor 62 is fixed to the fan motor base 63. The fan motor base 63 is fixed to the inner surface of the front plate 53. The bell mouth 64 is fixed to the inner surface of the front plate 53 along the inner surface of the front plate 53 and is arranged to cover the periphery of the blower fan 39. The air flow generated by the blower fan 39 flows from the back side of the outdoor unit 30 through the outdoor heat exchanger 34, through the opening of the bell mouth 64 and the blowout hole of the front plate 53, and to the outside of the outdoor unit 30.

  A top plate 57 is fixed to the top of the front plate 53, the left side plate 54 and the right side plate 55. A space in the casing 40 surrounded by the bottom plate 51, the front plate 53, the left side plate 54, the right side plate 55 and the top plate 57 is partitioned by a partition plate 52 fixed to the bottom plate 51, the front plate 53 and the right side plate 55. Thereby, the said space is divided into the machine room where the compressor 31 etc. are arrange | positioned, and the ventilation chamber where the ventilation fan 39 etc. are arrange | positioned. The partition plate 52 also serves as a barrier against noise so that noise generated by vibration of the compressor 31 and the like does not leak through the ventilation chamber and leak to the outside. An electrical component box 65 or the like is attached to the partition plate 52.

(4) Configuration and Mounting Method of Vibration Absorbing Material 70 FIG. 4 is a schematic perspective view of the compressor 31 and its peripheral portion as viewed obliquely from above.

  As shown in FIGS. 2 to 4, a vibration absorbing material 70 is attached to the curved portion 43 b of the refrigerant pipe 43 on the suction side of the compressor 31.

  FIG. 5 is a schematic cross-sectional view in which the vibration absorbing material 70 and its periphery are cut along a vertical plane.

  The vibration absorbing material 70 includes a rubber-like member 71 as an example of an elastic body and a film 72. This rubber-like member 71 has a synthetic rubber such as butyl rubber as a main component, and has a thickness in a range of about 3 mm to about 10 mm. For example, a thickness of 5 mm is preferable. In the first embodiment, for example, a substantially rectangular parallelepiped rubber-like member 71 having a width of about 30 mm and a length of about 170 mm is used. A film 72 made of a heat-resistant plastic such as a polyester film is attached to one surface of such a rubber-like member 71. In addition, an adhesive material is applied to the other surface of the rubber-like member 71 (the surface opposite to the surface to which the film 72 is attached). The adhesive surfaces 73, 74, 75, and 76 to which the adhesive material has been applied are protected with a release film or the like until they are adhered to an object.

  A plate magnet 100 made of a neodymium magnet, a ferrite magnet, or the like is embedded in one end of the rubber-like member 71. The width and thickness of the plate magnet 100 are smaller than the width and thickness of the rubber-like member 71. The plate magnet 100 is positioned so that each part of the plate magnet 100 is not exposed from the rubber-like member 71. At this time, the thickness of the rubber-like member 71 interposed between the plate magnet 100 and the bottom plate 51 is set within a range of 1 mm to 5 mm.

  When attaching the vibration absorbing material 70, by winding a part of the rubber-like member 71 with the film 72 around the curved portion 43b of the refrigerant pipe 43 and sticking one end of the rubber-like member 71 to the bottom plate 51, The curved portion 43b is connected to the bottom plate 51 via the rubber-like member 71. That is, the state of FIG. 5 is obtained. Such winding and pasting operations can be easily performed manually by an operator without using a tool because the film 72 is thin and the rubber-like member 71 is also softly adjusted.

  One end portion 70 a of the vibration absorbing material 70 is a portion wound around the curved portion 43 b in the vibration absorbing material 70, and is adhered to the curved portion 43 b by the adhesive material of the adhesive surface 74. For this reason, most of the stress that vibrates the bending portion 43 b is applied to the vibration absorbing material 70. The one end portion 70a of the vibration absorbing material 70 is an example of a first end portion.

  Further, the vibration absorbing material 70 has a connecting portion 70b in the vicinity of one end portion 70a. The connecting portion 70b is formed by bonding the adhesive surfaces 75 and 76 coated with an adhesive material. Therefore, even if the adhesive material of the adhesive surface 74 becomes weak, if the adhesive materials of the adhesive surfaces 75 and 76 are not weakened, the state where one end portion 70a of the vibration absorbing material 70 is wound around the curved portion 43b is maintained. You can continue.

  The other end portion 70 c of the vibration absorbing material 70 is a portion extending along the bottom plate 51 of the casing 40, and is attached to the surface of the bottom plate 51 by the adhesive material of the adhesive surface 73, and is in surface contact with the surface. It is the part which is doing. The length L of the other end 70c of the vibration absorbing material 70 is often set within a range of about 15 mm to about 20 mm, but may be 10 mm or more. If the length L of the other end portion 70 c of the vibration absorbing material 70 is at least 10 mm, the other end portion 70 c of the vibration absorbing material 70 can be prevented from separating from the bottom plate 51. Here, the length L of the other end portion 70 c of the vibration absorbing material 70 is a length in a direction parallel or substantially parallel to the longitudinal direction of the rubber-like member 71. The other end portion 70c of the vibration absorbing material 70 is an example of a second end portion.

  According to the above configuration, one end portion 70 a of the vibration absorbing material 70 is attached to the curved portion 43 b of the refrigerant pipe 43. On the other hand, the other end portion 70 c of the vibration absorbing material 70 is attached to the bottom plate 51 of the casing 40. That is, the curved portion 43 b of the refrigerant pipe 43 and the bottom plate 51 of the casing 40 are physically connected to each other via the vibration absorbing material 7. As a result, since the vibration of the refrigerant pipe 43 can be absorbed by the vibration absorber 70, the vibration of the refrigerant pipe 43 can be suppressed over the entire operating frequency of the compressor 31.

  Further, since the other end portion 70 c of the vibration absorbing material 70 is in surface contact with the bottom plate 51 of the casing 40, the vibration absorbing material 70 can effectively transmit the vibration of the refrigerant pipe 43 to the bottom plate 51 of the casing 40. . Therefore, the vibration of the refrigerant pipe 43 can be sufficiently damped.

  Further, since the other end portion 70 c of the vibration absorbing material 70 is attached to the bottom plate 51 of the casing 40 by the adhesive material of the adhesive surface 73, when the vibration of the refrigerant pipe 43 increases, the other end of the vibration absorbing material 70. The portion 70c slides back and forth in small increments on the bottom plate 51 of the casing 40. As a result, a part of the vibration energy of the refrigerant pipe 43 is consumed as frictional heat generated between the bottom plate 51 of the casing 40 and the other end 70 c of the vibration absorber 70. Therefore, the vibration of the bottom plate 51 of the casing 40 can also be reduced.

  Further, the adhesive strength of the adhesive surface 73 is weakened due to deterioration over time, or weakened due to adhesion of water. Thus, even if the adhesive force of the adhesive surface 73 becomes weak, the plate magnet 100 is embedded in the other end portion 70c of the vibration absorbing material 70, so that the other end portion 70c of the vibration absorbing material 70 and The surface contact with the bottom plate 51 of the casing 40 can be maintained semipermanently. Therefore, it is possible to prevent the vibration damping effect of the refrigerant pipe 43 from becoming small due to deterioration over time.

  Even if the adhesive force of the adhesive surface 73 becomes weak due to deterioration over time, the plate magnet 100 is embedded in the other end portion 70 c of the vibration absorbing material 70, and therefore the vibration absorbing material on the bottom plate 51 of the casing 40. The other end 70c of 70 can be slid back and forth in small increments.

  FIG. 6 is a graph showing the relationship between the operating frequency of the compressor 31 and the stress value of the refrigerant pipe 43. Here, the stress value of the refrigerant pipe 43 is detected by a strain gauge attached to a bent part (a part surrounded by a circle P in FIG. 4) provided between the curved part 43b and the four-way switching valve 32 in the refrigerant pipe 43. It is the value.

  When the vibration absorbing material 70 is used, as shown by the dotted line in FIG. 6, when the operating frequency of the compressor 31 is 45 Hz or more, the vibration of the refrigerant pipe 43 increases and a large stress is generated in the refrigerant pipe 43. I understand that. On the other hand, when the vibration absorbing material 70 is not used, as shown by the solid line in FIG. 6, the vibration of the refrigerant pipe 43 is suppressed regardless of the operation frequency of the compressor 31 within the range of 35 Hz to 55 Hz. It can be seen that large stress is prevented from being generated in the refrigerant pipe 43.

  In the first embodiment, one end portion 70 a of the vibration absorber 70 is directly attached to the curved portion 43 b of the refrigerant pipe 43, but one end of the vibration absorber 70 is attached to the curved portion 43 b of the refrigerant pipe 43. You may attach the part 70a indirectly. That is, one end portion 70 a of the vibration absorbing material 70 may be attached to a member that is fixed to the curved portion 43 b of the refrigerant pipe 43 and vibrates together with the refrigerant pipe 43.

  In the first embodiment, the other end portion 70 c of the vibration absorbing material 70 is directly attached to the bottom plate 51 of the casing 40, but the other end portion 70 c of the vibration absorbing material 70 is indirectly attached to the bottom plate 51 of the casing 40. May be attached. That is, the other end portion 70 c of the vibration absorbing material 70 may be attached to the metal portion fixed to the bottom plate 51 of the casing 40.

  In the first embodiment, the adhesive surface 73 is provided at the other end portion 70c of the vibration absorbing material 70. However, the adhesive surface may not be provided at the other end portion 70c of the vibration absorbing material 70. That is, the other end portion 70 c of the vibration absorbing material 70 may be attached to the bottom plate 51 of the casing 40 only by the magnetic force of the plate magnet 100.

  In the first embodiment, one end portion 70 a of the vibration absorbing material 70 is attached to a part of the refrigerant pipe 43 that is indirectly connected to the compressor 31, but is directly connected to the compressor 31. A part of the refrigerant pipe 41 or the refrigerant pipe 42 may be attached. That is, the refrigerant pipe 41 or a part of the refrigerant pipe 42 and the bottom plate 51 of the casing 40 may be physically connected to each other by the vibration absorber 70. Here, when a part of the refrigerant pipe 41 and the bottom plate 51 of the casing 40 are physically connected to each other by the vibration absorbing material 70, the refrigerant pipe 41 is a pipe on the discharge side of the compressor 31, and thus has high heat resistance. A material is preferably used as the material of the vibration absorber 70.

  In the first embodiment, the bottom plate 51, the front plate 53, the left side plate 54, the right side plate 55, the shut-off valve cover 56, and the top plate 57 are each formed of metal, but the front plate 53, the left side plate 54, Of the right side plate 55, the closing valve cover 56, and the top plate 57, a member that is not connected to the other end portion 70c of the vibration absorbing material 70 may be formed of a material other than metal. In other words, among the bottom plate 51, the front plate 53, the left side plate 54, the right side plate 55, the closing valve cover 56 and the top plate 57, at least a member connected to the other end portion 70c of the vibration absorbing material 70. Is made of metal.

  In the first embodiment, the other end portion 70c of the vibration absorbing material 70 is connected to the surface of the bottom plate 51 of the casing 40. For example, it is connected to the surface of a metal plate fixed to the outdoor heat exchanger 34. May be. The metal plate is an example of a metal member.

  In the first embodiment, each part of the plate magnet 100 is not exposed from the rubber-like member 71, but a part of the upper surface of the plate magnet 100 may be exposed.

  In the first embodiment, the casing 40 includes the bottom plate 51. However, the casing 40 may include a bottom plate 151 illustrated in FIG. On the surface of the bottom plate 151, a rib 151a facing the other end portion 70c of the vibration absorbing material 70 is provided as an example of a movement restricting portion. In this case, the other end portion 70 c of the vibration absorbing material 70 is attached to the surface of the bottom plate 151 at a predetermined distance from the rib 151. Accordingly, the possibility that the other end portion 70c of the vibration absorbing material 70 moves greatly and comes into contact with other members or the like can be reduced while allowing the other end portion 70c of the vibration absorbing material 70 to be reciprocated in small steps. . Therefore, it is possible to prevent the vibration of the refrigerant pipe 43 from propagating to an unintended location.

  Moreover, since the rib 151a is provided on the surface of the bottom plate 151, the strength of the bottom plate 151 can be increased.

  The rib 151a may have a shape (for example, an annular shape) surrounding the other end portion 70c of the vibration absorbing material 70, or a shape not surrounding the other end portion 70c of the vibration absorbing material 70. (For example, a plate shape) may be used.

[Second Embodiment]
FIG. 8 is a schematic cross-sectional view of the vibration absorbing material 270 and the periphery thereof according to the second embodiment of the present invention cut along a vertical plane. In FIG. 8, the magnetic powder 200 is shown exaggerated and enlarged, and the same reference numerals as those in FIG. 5 are assigned to the same components as those in FIG.

  In the second embodiment, the vibration absorbing material 270 is used to physically connect the curved portion 43b of the refrigerant pipe 43 and the bottom plate 51 of the casing 40 to each other.

  The vibration absorber 270 differs from the vibration absorber 70 of the first embodiment only in that the magnetized magnetic powder 200 is embedded in the rubber-like member 271 instead of the plate magnet 100. The magnetic powder 200 is an example of a magnetized magnetic body.

  The rubber-like member 271 is mainly composed of synthetic rubber such as butyl rubber, and has the same shape as the rubber-like member 71 of the first embodiment. A film 72 made of heat-resistant plastic such as a polyester film is attached to one surface of the rubber-like member 271. In addition, an adhesive material is applied to the other surface of the rubber-like member 271 (the surface opposite to the surface to which the film 72 is attached). The adhesive surfaces 273, 274, 275, 276 to which the adhesive material has been applied are protected with a release film or the like until they are adhered to the object.

  The magnetic powder 200 is obtained by magnetizing magnetic powder such as neodymium powder and ferrite powder. The magnetic powder 200 is embedded in each part of the rubber-like member 271. Further, the content of the magnetic powder 200 in each part of the rubber-like member 271 is substantially the same.

  Such a vibration absorber 270 is attached to the curved portion 43b of the refrigerant pipe 43 and the bottom plate 51 of the casing 40 in the same manner as the vibration absorber 70 of the first embodiment. That is, one end portion 270 a of the vibration absorbing material 270 is a portion that is wound around the curved portion 43 b of the refrigerant pipe 43 and attached to the curved portion 43 b of the refrigerant pipe 43. On the other hand, the other end portion 270 c of the vibration absorbing material 270 is a portion extending along the bottom plate 51 of the casing 40, and is attached to the bottom plate 51 by the adhesive material of the adhesive surface 273 and is in surface contact with the bottom plate 51. It is a part that. The connecting portion 270b of the vibration absorbing material 270 is a portion provided between the one end 270a and the other end 270c, and the adhesive surfaces 275 and 276 coated with the adhesive material are bonded together. It is formed. The one end 270a of the vibration absorbing material 270 is an example of a first end. The other end 270c of the vibration absorbing material 270 is an example of a second end.

  In addition, the connecting portion 270b includes a first portion provided with the adhesive surface 275 and a second portion provided with the adhesive surface 276. The magnetic powder in the first and second parts is magnetized so that the magnetic powder in the first part and the magnetic powder in the second part attract each other.

  According to the said structure, the effect similar to the said 1st Embodiment is acquired. Further, even if the magnetic powder 200 is embedded in each part of the rubber-like member 271, the density of the rubber-like member 271 does not greatly decrease. Therefore, it is possible to prevent the vibration transmission function of the vibration absorbing material 270 from being lowered.

  Further, the magnetic powder 200 in the first portion on the adhesive surface 275 side of the connecting portion 270b and the magnetic powder 200 in the second portion on the adhesive surface 276 side of the connecting portion 270b attract each other. As a result, even if the adhesive material of the adhesive surfaces 275 and 276 becomes weak due to aging, the state where the adhesive surfaces 275 and 276 are bonded together can be maintained. Therefore, the state where one end portion 270a of the vibration absorbing material 270 is wound around the curved portion 43b can be maintained.

  In the second embodiment, the magnetic powder 200 is embedded substantially uniformly in each part of the rubber-like member 271, but as shown in FIG. 9, the magnetic powder 200 is embedded only in the portion on the bottom plate 51 side of the rubber-like member 371. But you can.

  In the case of FIG. 9, the content of the magnetic powder 200 at the other end 370 c of the vibration absorbing material 370 as compared with the content of the magnetic powder 200 at the one end 370 a and the connecting portion 370 b of the vibration absorbing material 370. Will increase. In other words, the content of the magnetic powder 200 at one end 370a of the vibration absorbing material 370 and the connecting portion 370b is smaller than the content of the magnetic powder 200 at the other end 370c of the vibration absorbing material 370. . Therefore, the content of the magnetic powder 200 in one end portion 370a and the connecting portion 370b of the vibration absorbing material 370 can be lowered, and the material cost can be reduced.

  In FIG. 9, reference numerals 373, 374, 375, and 376 denote adhesive surfaces to which an adhesive material is applied. The one end 370a of the vibration absorbing material 370 is an example of a first end. The other end 370c of the vibration absorbing material 370 is an example of a second end.

  Although specific first and second embodiments of the present invention and modifications thereof have been described, the present invention is not limited to the first and second embodiments and modifications thereof, and is within the scope of the present invention. Various modifications can be made. For example, a combination of the contents described in the first embodiment and the contents described in the second embodiment may be used as an embodiment of the present invention.
