Description

空気調和機の室外機Outdoor unit of air conditioner
　本発明は、騒音の低減を図った空気調和機の室外機に関する。 The present invention relates to an outdoor unit of an air conditioner that reduces noise.
　従来、空気調和機の室外機の筐体には、機械室が形成されている。そして、機械室には、圧縮機が収納されている。圧縮機が駆動して該圧縮機が振動した際、圧縮機に接続されている冷媒配管を介して圧縮機の振動が室外機全体に伝わり、騒音が発生する場合がある。このため、従来の空気調和機の室外機には、圧縮機に接続されている冷媒配管の振動の低減を図ったものが提案されている（特許文献１参照）。具体的には、特許文献１に記載の空気調和機の室外機は、圧縮機に接続されている冷媒配管の水平に延びる箇所に、ブチルゴム等で形成された制振部材が巻き付けられている。また、特許文献１に記載の空気調和機の室外機は、制振部材を挟み込み、圧縮機に接続されている冷媒配管の水平に延びる箇所からの制振部材の落下を防止する保持部材を備えている。 Conventionally, a machine room is formed in the housing of the outdoor unit of the air conditioner. A compressor is stored in the machine room. When the compressor is driven and the compressor vibrates, the vibration of the compressor is transmitted to the entire outdoor unit via the refrigerant pipe connected to the compressor, and noise may be generated. Therefore, as an outdoor unit of a conventional air conditioner, a device that reduces vibration of a refrigerant pipe connected to a compressor has been proposed (see Patent Document 1).

　室外機に収納されている圧縮機の周囲は、空間が乏しい。このため、圧縮機に接続されている冷媒配管の水平に延びる箇所に、制振部材を巻き付けることが困難な場合がある。このため、従来の空気調和機の室外機は、圧縮機の周囲の空間が乏しい場合、圧縮機に接続されている冷媒配管の振動を低減できない場合があるという課題があった。 There is not enough space around the compressor stored in the outdoor unit. Therefore, it may be difficult to wind the vibration damping member around a horizontally extending portion of the refrigerant pipe connected to the compressor. Therefore, the outdoor unit of the conventional air conditioner has a problem that the vibration of the refrigerant pipe connected to the compressor may not be reduced when the space around the compressor is scarce.
　本発明は、上述の課題を解決するためになされたものであり、従来の制振部材を設けることができない場合であっても、圧縮機に接続されている冷媒配管の振動を低減することができる空気調和機の室外機を提供することを目的とする。 The present invention has been made to solve the above-mentioned problems, and it is possible to reduce the vibration of the refrigerant pipe connected to the compressor even when the conventional vibration damping member cannot be provided.

A first vibration damping member, in which the refrigerant pipe is inserted into the first through hole and fixed to the upper part of the closed container, is provided.
　本発明に係る空気調和機の室外機の第１制振部材は、第１貫通孔に冷媒配管が挿入された状態で、圧縮機の密閉容器に固定されている。このため、本発明に係る空気調和機の室外機の第１制振部材は、従来の制振部材を設けることができない場合であっても、冷媒配管に設けることができる。したがって、本発明に係る空気調和機の室外機は、従来の制振部材を設けることができない場合であっても、圧縮機に接続されている冷媒配管の振動を低減することができる。 The first vibration damping member of the outdoor unit of the air conditioner according to the present invention is fixed to the closed container of the compressor with the refrigerant pipe inserted in the first through hole. Therefore, the first vibration damping member of the outdoor unit of the air conditioner according to the present invention can be provided in the refrigerant pipe even when the conventional vibration damping member cannot be provided. Therefore, the outdoor unit of the air conditioner according to the present invention can reduce the vibration of the refrigerant pipe connected to the compressor even when the conventional vibration damping member cannot be provided.

The refrigerant outlet of the suction muffler 43 is connected to the refrigerant inlet of the main body 41. Then, the gaseous refrigerant is supplied from the suction muffler 43 to the main body 41. This gaseous refrigerant is compressed by the compression mechanism of the main body 41 and then discharged from the main body 41. That is, the inflow port of the refrigerant of the suction muffler 43 is the suction port of the refrigerant of the compressor 40. Further, the outlet of the refrigerant of the main body 41, in other words, the outlet of the refrigerant of the container 42 is the discharge port of the refrigerant of the compressor 40.

The four-way switching valve 11 switches the connection destination of the refrigerant discharge port of the compressor 40 to the outdoor heat exchanger 12 or the indoor heat exchanger 13. 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.
　室外熱交換器１２は、暖房運転時には蒸発器として機能し、冷房運転時には凝縮器として機能する。なお、本実施の形態１では、室外熱交換器１２の近傍に、ファン２１が設けられている。ファン２１は、室外熱交換器１２に、室外熱交換器１２を流れる冷媒の熱交換対象である室外空気を供給する。このファン２１は、モータ２２によって駆動される。室内熱交換器１３は、暖房運転時には凝縮器として機能し、冷房運転時には蒸発器として機能する。膨張弁１４は、室外熱交換器１２と室内熱交換器１３とを接続する冷媒配管に設けられており、室外熱交換器１２を流れる冷媒の流量を調節する。膨張弁１５は、室外熱交換器１２と室内熱交換器１３とを接続する冷媒配管において膨張弁１４よりも室内熱交換器１３側となる位置に設けられており、室内熱交換器１３を流れる冷媒の流量を調節する。 The outdoor heat exchanger 12 functions as an evaporator during the heating operation and as a condenser during the cooling operation. In the first embodiment, the fan 21 is provided in the vicinity of the outdoor heat exchanger 12. The fan 21 supplies the outdoor heat exchanger 12 with outdoor air that is a heat exchange target of the refrigerant flowing through 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 as an evaporator during the cooling operation.

　空気調和機１を構成する上述の各構成は、室外機２又は室内機３に収納されている。具体的には、室外機２には、四方切替弁１１、室外熱交換器１２、膨張弁１４、ファン２１、モータ２２、圧力センサ３１、圧力センサ３２、温度センサ３３、温度センサ３４、制御装置３８、及び圧縮機４０が収納されている。室内機３には、室内熱交換器１３、膨張弁１５、温度センサ３５、温度センサ３６、及び温度センサ３７が収納されている。また、本実施の形態１に係る空気調和機１では、室外機２に設けられた冷凍サイクル回路１０の構成と室内機３に設けられた冷凍サイクル回路１０の構成とを接続する冷媒配管に、開閉弁１６及び開閉弁１７が設けられている。開閉弁１６及び開閉弁１７は、室外機２に収納されている。なお、本実施の形態１に係る空気調和機１は、２つの室内機３を備えている。これらの室内機３は、並列に、室外機２に接続されている。 Each of the above-mentioned configurations constituting the air conditioner 1 is housed in the outdoor unit 2 or the indoor unit 3.

　室外機２は、例えば略直方体の外郭部５０を備えている。また、外郭部５０には、室外機２を移動させる際に作業者が把持する複数の取手５９が設けられている。外郭部５０の構成の仕方は特に限定されないが、本実施の形態１では、天面パネル５１、ベース５２、正面パネル５３、サービスパネル５４、右側面パネル５５、左側面パネル５６、カバーパネル５７及びカバーパネル５８で、外郭部５０を構成している。 FIG. 2 is a perspective view of the outdoor unit according to the first embodiment as viewed from the front right side.

The cover panel 58 constitutes a lower portion on the rear side of the right side surface portion of the outer shell portion 50 and a lower portion on the right side of the back surface portion of the outer shell portion 50.
　外郭部５０の内部は、仕切板６０によって、送風機室６１と機械室６２とに区画されている。送風機室６１には、室外熱交換器１２が収納されている。また、図３には図示していないが、送風機室６１には、ファン２１及びモータ２２も収納されている。また、機械室６２には、圧縮機４０が収納されている。 The inside of the outer shell 50 is divided into a blower room 61 and a machine room 62 by a partition plate 60. The outdoor heat exchanger 12 is housed in the blower room 61. Although not shown in FIG. 3, the fan 21 and the motor 22 are also housed in the blower chamber 61. Further, the compressor 40 is housed in the machine room 62.
　従来、空気調和機の運転が開始され、圧縮機が駆動されると、圧縮機が振動する。そして、この圧縮機の振動によって騒音が発生する場合がある。このため、従来の空気調和機には、圧縮機の周囲を囲う防音材を備えたものも存在する。本実施の形態１に係る空気調和機１も、圧縮機４０の周囲を囲う防音材７０を備えている。防音材７０は、従来より存在する防音材と同様の構成である。例えば、防音材７０は、以下のように構成されている。 Conventionally, when the operation of the air conditioner is started and the compressor is driven, the compressor vibrates. Then, noise may be generated due to the vibration of this compressor. For this reason, some conventional air conditioners are provided with a soundproofing material that surrounds the compressor. The air conditioner 1 according to the first embodiment also includes a soundproofing material 70 that surrounds the compressor 40. The soundproofing material 70 has the same structure as the conventional soundproofing material. For example, the soundproofing material 70 is configured as follows.
　図４は、実施の形態１に係る室外機の圧縮機周辺を側方から観察した図である。この図４では、防音材７０を断面で示している。
　圧縮機４０の側方及び上方は、防音材７０で囲われている。防音材７０は、外郭部を構成する、ゴムで形成されたゴム部７１を備えている。すなわち、ゴム部７１は、外郭部の形状を維持できる剛性を有し、遮音性を有する。また、防音材７０は、ゴム部７１の内周面に、換言するとゴム部７１の圧縮機４０と対向する側の面に、不織布７２が設けられている。不織布７２は、吸音効果を有する。 FIG. 4 is a side view of the periphery of the compressor of the outdoor unit according to the first embodiment. In FIG. 4, the soundproofing material 70 is shown in cross section.
The side and the upper side of the compressor 40 are surrounded by a soundproofing material 70. The soundproofing material 70 includes a rubber portion 71 made of rubber, which constitutes an outer shell portion. That is, the rubber portion 71 has rigidity that can maintain the shape of the outer shell portion and has sound insulation. Further, the soundproofing material 70 is provided with a non-woven 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 non-woven fabric 72 has a sound absorbing effect.
　ここで、従来、圧縮機が振動すると、圧縮機に接続されている冷媒配管も振動する。このため、圧縮機に接続されている冷媒配管を介して圧縮機の振動が室外機全体に伝わり、騒音が発生する場合がある。したがって、従来の空気調和機の室外機では、圧縮機に接続されている冷媒配管の水平に延びる箇所に特許文献１に記載の制振部材を巻き付けることにより、圧縮機に接続されている冷媒配管の振動の低減を図っていた。しかしながら、室外機に収納されている圧縮機の周囲は、空間が乏しい。このため、圧縮機に接続されている冷媒配管の水平に延びる箇所に、制振部材を巻き付けることが困難な場合がある。このため、従来の空気調和機の室外機は、圧縮機の周囲の空間が乏しい場合、圧縮機に接続されている冷媒配管の振動を低減できない場合があった。 Here, conventionally, when the compressor vibrates, the refrigerant pipe connected to the compressor also vibrates. Therefore, the vibration of the compressor may be transmitted to the entire outdoor unit through the refrigerant pipe connected to the compressor, and noise may be generated. Therefore, in the outdoor unit of a conventional air conditioner, the refrigerant pipe connected to the compressor is connected to the compressor by winding the vibration damping member described in Patent Document 1 around a horizontally extending portion of the refrigerant pipe connected to the compressor. I was trying to reduce the vibration of the air conditioner. However, the space around the compressor housed in the outdoor unit is scarce. Therefore, it may be difficult to wind the vibration damping member around a horizontally extending portion of the refrigerant pipe connected to the compressor. Therefore, the outdoor unit of the conventional air conditioner may not be able to reduce the vibration of the refrigerant pipe connected to the compressor when the space around the compressor is scarce.
　そこで、本実施の形態１に係る室外機２は、第１制振部材８０を備えている。 Therefore, the outdoor unit 2 according to the first embodiment is provided with the first vibration damping member 80.
　図５は、実施の形態１に係る室外機の圧縮機周辺を上方から観察した図である。以下、図４及び図５を用いて、第１制振部材８０を説明する。
　第１制振部材８０は、ブチルゴム等のような従来の制振部材で用いられているゴムで形成されている。第１制振部材８０には、上下方向に貫通する第１貫通孔８１が形成されている。第１貫通孔８１には、該第１貫通孔８１の内周面に吸入配管１８の外周面が触れるように、吸入配管１８が挿入されている。そして、第１制振部材８０は、密閉容器であるサクションマフラ４３の上部に固定されている。第１制振部材８０とサクションマフラ４３との固定方法は、特に限定されない。例えば、第１制振部材８０は、両面テープ、糊又は接着剤等により、サクションマフラ４３の上部に固定されている。 FIG. 5 is a view of the periphery of the compressor of the outdoor unit according to the first embodiment observed from above. Hereinafter, the first vibration damping member 80 will be described with reference to FIGS. 4 and 5.
The first vibration damping member 80 is made of rubber used in conventional vibration damping members such as butyl rubber. The first vibration damping member 80 is formed with a first through hole 81 that penetrates in the vertical direction. The suction pipe 18 is inserted into the first through hole 81 so that the outer peripheral surface of the suction pipe 18 touches the inner peripheral surface of the first through hole 81. The first vibration damping member 80 is fixed to the upper part of the suction muffler 43, which is a closed container. The method of fixing the first vibration damping member 80 and the suction muffler 43 is not particularly limited. For example, the first vibration damping member 80 is fixed to the upper part of the suction muffler 43 with double-sided tape, glue, an adhesive, or the like.
　このように構成された第１制振部材８０は、従来の制振部材を吸入配管１８に設けることができない場合であっても、吸入配管１８に設けることができる。すなわち、このように構成された第１制振部材８０は、従来の制振部材を吸入配管１８に設けることができない場合であっても、吸入配管１８の振動を低減することができ、圧縮機４０の振動が室外機２全体に伝わることによって発生する騒音を低減することができる。 The first vibration damping member 80 configured in this way can be provided in the suction pipe 18 even when the conventional vibration damping member cannot be provided in the suction pipe 18. That is, the first vibration damping member 80 configured in this way can reduce the vibration of the suction pipe 18 even when the conventional vibration damping member cannot be provided in the suction pipe 18, and is a compressor. The noise generated by the vibration of 40 being transmitted to the entire outdoor unit 2 can be reduced.
　また、従来の制振部材は、制振部材の落下を防止する保持部材が必要であった。一方、本実施の形態１に係る第１制振部材８０は、従来の制振部材が必要としていた保持部材が不要となる。このため、第１制振部材８０を用いることにより、従来よりも安価に騒音を低減することもできる。 In addition, the conventional damping member required a holding member to prevent the damping member from falling. On the other hand, the first vibration damping member 80 according to the first embodiment eliminates the need for the holding member required by the conventional vibration damping member. Therefore, by using the first vibration damping member 80, it is possible to reduce noise at a lower cost than before.
　また、本実施の形態１に係る第１制振部材８０は、サクションマフラ４３の上部に固定されているので、サクションマフラ４３の振動を抑制することもできる。このため、本実施の形態１に係る第１制振部材８０は、従来の制振部材と比べ、圧縮機４０の振動をより抑制できる。すなわち、本実施の形態１に係る第１制振部材８０は、従来の制振部材と比べ、圧縮機４０の振動が室外機２全体に伝わることによって発生する騒音をより低減することができる。 Further, since the first vibration damping member 80 according to the first embodiment is fixed to the upper part of the suction muffler 43, the vibration of the suction muffler 43 can be suppressed. Therefore, the first vibration damping member 80 according to the first embodiment can further suppress the vibration of the compressor 40 as compared with the conventional vibration damping member. That is, the first vibration damping member 80 according to the first embodiment can further reduce the noise generated by the vibration of the compressor 40 being transmitted to the entire outdoor unit 2 as compared with the conventional vibration damping member.
　また、従来、圧縮機に冷媒配管を接続することによって圧縮機の重心が移動し、圧縮機の振動が大きくなる場合がある。また、圧縮機の重心が移動すると、圧縮機が振動した際の圧縮機の可動域が変わる。そして、圧縮機の可動域が変わることによって、圧縮機に接続された冷媒配管が圧縮機を囲う防音材に接触し、騒音が発生する場合がある。これに対し、本実施の形態１に係る第１制振部材８０をサクションマフラ４３に固定することにより、圧縮機４０の重心を移動させることができる。このため、吸入配管１８及び吐出配管１９を圧縮機４０に接続した後の該圧縮機４０の重心を、吸入配管１８及び吐出配管１９が接続される前の圧縮機４０の重心位置の近くに、移動させることができる。このため、本実施の形態１に係る第１制振部材８０を用いることにより、圧縮機４０の重心移動によって発生する騒音を抑制することもできる。 Also, conventionally, by connecting the refrigerant pipe to the compressor, the center of gravity of the compressor may move and the vibration of the compressor may increase. Further, when the center of gravity of the compressor moves, the range of motion of the compressor when the compressor vibrates changes. Then, as the range of motion of the compressor changes, the refrigerant pipe connected to the compressor may come into contact with the soundproofing material surrounding the compressor, and noise may be generated. On the other hand, by fixing the first vibration damping member 80 according to the first embodiment to the suction muffler 43, the center of gravity of the compressor 40 can be moved. Therefore, the center of gravity of the compressor 40 after the suction pipe 18 and the discharge pipe 19 are connected to the compressor 40 is set close to the position of the center of gravity of the compressor 40 before the suction pipe 18 and the discharge pipe 19 are connected. Can be moved. Therefore, by using the first vibration damping member 80 according to the first embodiment, it is possible to suppress the noise generated by the movement of the center of gravity of the compressor 40.
　また、本実施の形態１に係る第１制振部材８０には、該第１制振部材８０の外周面と第１貫通孔８１の内周面との間を切断する切り込み８２が形成されている。第１制振部材８０に切り込み８２を形成することにより、横方向から第１貫通孔８１に吸入配管１８を入れることができ、第１制振部材８０の取り付けが容易となる。 Further, the first vibration damping member 80 according to the first embodiment is formed with a notch 82 for cutting between the outer peripheral surface of the first vibration damping member 80 and the inner peripheral surface of the first through hole 81. There is. By forming the notch 82 in the first vibration damping member 80, the suction pipe 18 can be inserted into the first through hole 81 from the lateral direction, and the first vibration damping member 80 can be easily attached.
　なお、第１制振部材８０は、圧縮機４０の本体部４１に設けられていてもよい。具体的には、第１貫通孔８１に、該第１貫通孔８１の内周面に吐出配管１９の外周面が触れるように、吐出配管１９を挿入すればよい。そして、密閉容器である本体部４１の容器４２の上部に、第１制振部材８０を固定すればよい。これにより、従来の制振部材を吐出配管１９に設けることができない場合であっても、吐出配管１９の振動を低減することができ、圧縮機４０の振動が室外機２全体に伝わることによって発生する騒音を低減することができる。 The first vibration damping member 80 may be provided in the main body 41 of the compressor 40. Specifically, the discharge pipe 19 may be inserted into the first through hole 81 so that the outer peripheral surface of the discharge pipe 19 touches the inner peripheral surface of the first through hole 81. Then, the first vibration damping member 80 may be fixed to the upper part of the container 42 of the main body 41 which is a closed container. As a result, even when the conventional vibration damping member cannot be provided in the discharge pipe 19, the vibration of the discharge pipe 19 can be reduced, and the vibration of the compressor 40 is transmitted to the entire outdoor unit 2. It is possible to reduce the noise generated.
　また、第１制振部材８０を本体部４１の容器４２の上部に設けることにより、従来よりも安価に騒音を低減することもできる。また、第１制振部材８０を本体部４１の容器４２の上部に設けることにより、圧縮機４０の本体部４１の振動を抑制することができるので、従来の制振部材と比べ、圧縮機４０の振動が室外機２全体に伝わることによって発生する騒音をより低減することができる。また、第１制振部材８０を本体部４１の容器４２の上部に設けることにより、圧縮機４０の重心移動によって発生する騒音を抑制する効果を得ることもできる。 Further, by providing the first vibration damping member 80 on the upper part of the container 42 of the main body 41, noise can be reduced at a lower cost than before. Further, by providing the first vibration damping member 80 on the upper part of the container 42 of the main body 41, the vibration of the main body 41 of the compressor 40 can be suppressed, so that the compressor 40 is compared with the conventional vibration damping member. The noise generated by the vibration of the outdoor unit 2 being transmitted to the entire outdoor unit 2 can be further reduced. Further, by providing the first vibration damping member 80 on the upper part of the container 42 of the main body 41, it is possible to obtain the effect of suppressing the noise generated by the movement of the center of gravity of the compressor 40.
　以上、本実施の形態１に係る空気調和機１の室外機２は、圧縮機４０と、冷媒配管と、第１制振部材８０とを備えている。圧縮機４０は、密閉容器を備えている。冷媒配管は、上下方向に延び、圧縮機４０の密閉容器の上部に接続されている。第１制振部材８０は、上下方向に貫通する第１貫通孔８１が形成されている。そして、第１制振部材８０は、第１貫通孔８１に密閉容器の上部に接続されている冷媒配管が挿入されて、圧縮機４０の密閉容器の上部に固定されている。 As described above, the outdoor unit 2 of the air conditioner 1 according to the first embodiment includes a compressor 40, a refrigerant pipe, and a first vibration damping member 80. The compressor 40 includes a closed container. The refrigerant pipe extends in the vertical direction and is connected to the upper part of the closed container of the compressor 40. The first vibration damping member 80 is formed with a first through hole 81 that penetrates in the vertical direction. Then, the first vibration damping member 80 is fixed to the upper part of the closed container of the compressor 40 by inserting the refrigerant pipe connected to the upper part of the closed container into the first through hole 81.
　本実施の形態１に係る室外機２は、第１制振部材８０を備えているので、上述のように、従来の制振部材を設けることができない場合であっても、圧縮機４０に接続されている冷媒配管の振動を低減することができる。 Since the outdoor unit 2 according to the first embodiment includes the first vibration damping member 80, it is connected to the compressor 40 even when the conventional vibration damping member cannot be provided as described above. It is possible to reduce the vibration of the refrigerant pipe.
実施の形態２．
　第１制振部材８０の重量のみでは冷媒配管の振動を十分に低減できない場合、以下のような第２制振部材９０を追加してもよい。なお、本実施の形態２において、特に記述しない項目については実施の形態１と同様とし、実施の形態１と同一の機能及び構成については同一の符号を用いて述べることとする。 Embodiment 2.
If the weight of the first vibration damping member 80 alone cannot sufficiently reduce the vibration of the refrigerant pipe, the following second vibration damping member 90 may be added. In the second embodiment, items not particularly described are the same as those in the first embodiment, and the same functions and configurations as those in the first embodiment are described by using the same reference numerals.
　図６は、実施の形態２に係る室外機の圧縮機周辺を側方から観察した図である。また、図７は、実施の形態２に係る室外機の圧縮機周辺を上方から観察した図である。なお、図６では、防音材７０、第１制振部材８０及び第２制振部材９０を断面で示している。 FIG. 6 is a side view of the periphery of the compressor of the outdoor unit according to the second embodiment. Further, FIG. 7 is a view of the periphery of the compressor of the outdoor unit according to the second embodiment observed from above. In FIG. 6, the soundproofing material 70, the first vibration damping member 80, and the second vibration damping member 90 are shown in cross section.
　本実施の形態２に係る室外機２は、実施の形態１で示した構成に加えて、少なくとも１つの第２制振部材９０を備えている。第２制振部材９０は、ブチルゴム等のような従来の制振部材で用いられているゴムで形成されている。第２制振部材９０には、上下方向に貫通する第２貫通孔９１が形成されている。第２貫通孔９１には、該第２貫通孔９１の内周面に吸入配管１８の外周面が触れるように、吸入配管１８が挿入されている。そして、第２制振部材９０は、第１制振部材８０の上方に配置されている。第２制振部材９０は、例えば、第１制振部材８０に固定されている。第２制振部材９０の固定は、例えば、両面テープ、糊又は接着剤等が用いられる。 The outdoor unit 2 according to the second embodiment includes at least one second vibration damping member 90 in addition to the configuration shown in the first embodiment. The second vibration damping member 90 is made of rubber used in conventional vibration damping members such as butyl rubber. The second vibration damping member 90 is formed with a second through hole 91 that penetrates in the vertical direction. The suction pipe 18 is inserted into the second through hole 91 so that the outer peripheral surface of the suction pipe 18 touches the inner peripheral surface of the second through hole 91. The second vibration damping member 90 is arranged above the first vibration damping member 80. The second vibration damping member 90 is fixed to, for example, the first vibration damping member 80. For fixing the second vibration damping member 90, for example, double-sided tape, glue, an adhesive or the like is used.
　なお、図６及び図７では１つの第２制振部材９０のみを備えた室外機２を示しているが、室外機２は、第２制振部材９０を複数備えていてもよい。この場合、上下方向に並べて固定された複数の第２制振部材９０を第１制振部材８０の上方に配置すればよい。 Although FIGS. 6 and 7 show the outdoor unit 2 provided with only one second vibration damping member 90, the outdoor unit 2 may be provided with a plurality of second vibration damping members 90. In this case, a plurality of second vibration damping members 90 fixed side by side in the vertical direction may be arranged above the first vibration damping member 80.
　室外機２が第１制振部材８０に加えて第２制振部材９０も備えることにより、吸入配管１８のみが吸入配管１８に取り付けられている場合と比べ、吸入配管１８に取り付けられた制振部材の重量を大きくすることができる。このため、第１制振部材８０の重量のみでは吸入配管１８の振動を十分に低減できない場合、室外機２が第１制振部材８０に加えて第２制振部材９０も備えることにより、吸入配管１８の振動を低減することができる。 Since the outdoor unit 2 includes the second vibration damping member 90 in addition to the first vibration damping member 80, the vibration damping attached to the suction pipe 18 is compared with the case where only the suction pipe 18 is attached to the suction pipe 18. The weight of the member can be increased. Therefore, when the vibration of the suction pipe 18 cannot be sufficiently reduced only by the weight of the first vibration damping member 80, the outdoor unit 2 is provided with the second vibration damping member 90 in addition to the first vibration damping member 80 to suck. The vibration of the pipe 18 can be reduced.
　なお、図７に示すように、第２制振部材９０には、該第２制振部材９０の外周面と第２貫通孔９１の内周面との間を切断する切り込み９２が形成されていることが好ましい。第２制振部材９０に切り込み９２を形成することにより、横方向から第２貫通孔９１に吸入配管１８を入れることができ、第２制振部材９０の取り付けが容易となる。 As shown in FIG. 7, the second vibration damping member 90 is formed with a notch 92 that cuts between the outer peripheral surface of the second vibration damping member 90 and the inner peripheral surface of the second through hole 91. It is preferable to have. By forming the notch 92 in the second vibration damping member 90, the suction pipe 18 can be inserted into the second through hole 91 from the lateral direction, and the second vibration damping member 90 can be easily attached.
　また、図６及び図７に示すように、第１制振部材８０と上下方向に隣り合う第２制振部材９０には、凹部９３が形成されていることが好ましい。詳しくは、第１制振部材８０と上下方向に隣り合う第２制振部材９０を上方から見た際、第２制振部材９０の方が第１制振部材８０よりも大きくなっている。そして、第１制振部材８０と上下方向に隣り合う第２制振部材９０には、下方に配置された第１制振部材８０が収納された凹部９３が形成されている。 Further, as shown in FIGS. 6 and 7, it is preferable that the second vibration damping member 90 adjacent to the first vibration damping member 80 in the vertical direction is formed with a recess 93. Specifically, when the second vibration damping member 90 adjacent to the first vibration damping member 80 in the vertical direction is viewed from above, the second vibration damping member 90 is larger than the first vibration damping member 80. The second vibration damping member 90 adjacent to the first vibration damping member 80 in the vertical direction is formed with a recess 93 in which the first vibration damping member 80 arranged below is housed.
　第２制振部材９０に凹部９３を形成することにより、第２制振部材９０を、第１制振部材８０及びサクションマフラ４３の双方に固定可能となる。このため、例えば、第２制振部材９０が第１制振部材８０と接着しにくい材料で形成されている場合、第２制振部材９０とサクションマフラ４３とを固定することで、第２制振部材９０をしっかりと固定することができる。また例えば、第２制振部材９０がサクションマフラ４３と接着しにくい材料で形成されている場合、第２制振部材９０と第１制振部材８０とを固定することで、第２制振部材９０をしっかりと固定することができる。したがって、第２制振部材９０に凹部９３を形成することにより、第２制振部材９０の材料選定の幅が広がり、室外機２の設計の自由度が向上する。 By forming the recess 93 in the second vibration damping member 90, the second vibration damping member 90 can be fixed to both the first vibration damping member 80 and the suction muffler 43. Therefore, for example, when the second vibration damping member 90 is made of a material that is difficult to adhere to the first vibration damping member 80, the second damping member 90 and the suction muffler 43 are fixed to the second damping member 90. The vibration member 90 can be firmly fixed. Further, for example, when the second vibration damping member 90 is made of a material that is difficult to adhere to the suction muffler 43, the second vibration damping member 90 and the first vibration damping member 80 are fixed to form the second vibration damping member 90. The 90 can be firmly fixed. Therefore, by forming the recess 93 in the second vibration damping member 90, the range of material selection for the second vibration damping member 90 is widened, and the degree of freedom in designing the outdoor unit 2 is improved.
　なお、吐出配管１９に第１制振部材８０が取り付けられている場合、当該第１制振部材８０の上方に第２制振部材９０を配置しても勿論よい。 When the first vibration damping member 80 is attached to the discharge pipe 19, the second vibration damping member 90 may be arranged above the first vibration damping member 80.
実施の形態３．
　実施の形態１及び実施の形態２では、第１制振部材８０を上方から観察した際、第１貫通孔８１の中心が第１制振部材８０の重心位置となっていた。このような場合、第１制振部材８０を圧縮機４０に取り付けることにより、平面視において本体部４１及びサクションマフラ４３の並び方向となる方向に、圧縮機４０の重心を移動させることができる。平面視において本体部４１及びサクションマフラ４３の並び方向とは異なる方向に圧縮機４０の重心を移動させる場合、本実施の形態３のように第１制振部材８０を構成してもよい。なお、本実施の形態３において、特に記述しない項目については実施の形態１又は実施の形態２と同様とし、実施の形態１又は実施の形態２と同一の機能及び構成については同一の符号を用いて述べることとする。また、以下では、第１制振部材８０を吸入配管１８に取り付ける例を説明する。 Embodiment 3.
In the first and second embodiments, when the first vibration damping member 80 is observed from above, the center of the first through hole 81 is the position of the center of gravity of the first vibration damping member 80. In such a case, by attaching the first vibration damping member 80 to the compressor 40, the center of gravity of the compressor 40 can be moved in the direction in which the main body 41 and the suction muffler 43 are arranged in a plan view. When the center of gravity of the compressor 40 is moved in a direction different from the arrangement direction of the main body 41 and the suction muffler 43 in a plan view, the first vibration damping member 80 may be configured as in the third embodiment. In the third embodiment, items not particularly described are the same as those of the first embodiment or the second embodiment, and the same reference numerals are used for the same functions and configurations as those of the first embodiment or the second embodiment. Will be described. Further, an example of attaching the first vibration damping member 80 to the suction pipe 18 will be described below.
　図８は、実施の形態３に係る室外機の圧縮機周辺を上方から観察した図である。
　実施の形態３では、第１制振部材８０を上方から観察した際、第１貫通孔８１の中心が第１制振部材８０の重心と異なる位置に配置されている。このように第１制振部材８０を構成することにより、平面視において第１貫通孔８１の中心と第１制振部材８０の重心とが並ぶ方向に、圧縮機４０の重心を移動させることができる。図８の場合、平面視において本体部４１及びサクションマフラ４３の並び方向と垂直な方向に、圧縮機４０の重心を移動させることができる。 FIG. 8 is a view of the periphery of the compressor of the outdoor unit according to the third embodiment observed from above.
In the third embodiment, when the first vibration damping member 80 is observed from above, the center of the first through hole 81 is arranged at a position different from the center of gravity of the first vibration damping member 80. By configuring the first vibration damping member 80 in this way, the center of gravity of the compressor 40 can be moved in the direction in which the center of the first through hole 81 and the center of gravity of the first vibration damping member 80 are aligned in a plan view. it can. In the case of FIG. 8, the center of gravity of the compressor 40 can be moved in a direction perpendicular to the arrangement direction of the main body 41 and the suction muffler 43 in a plan view.
　吸入配管１８及び吐出配管１９を圧縮機４０に接続した際に、平面視において本体部４１及びサクションマフラ４３の並び方向と異なる方向に圧縮機４０の重心が移動する場合、本実施の形態３に示す第１制振部材８０を用いることにより、圧縮機４０の重心移動によって発生する騒音を抑制することができる。 When the suction pipe 18 and the discharge pipe 19 are connected to the compressor 40, when the center of gravity of the compressor 40 moves in a direction different from the arrangement direction of the main body 41 and the suction muffler 43 in a plan view, the present embodiment 3 By using the first vibration damping member 80 shown, the noise generated by the movement of the center of gravity of the compressor 40 can be suppressed.
　なお、室外機２が第２制振部材９０を備えている場合、第２制振部材９０を上方から観察した際、第２貫通孔９１の中心が第２制振部材９０の重心と異なる位置に配置されていてもよい。吸入配管１８及び吐出配管１９を圧縮機４０に接続した際に、平面視において本体部４１及びサクションマフラ４３の並び方向と異なる方向に圧縮機４０の重心が移動する場合、このように構成された第２制振部材９０を用いることにより、圧縮機４０の重心移動によって発生する騒音を抑制することができる。 When the outdoor unit 2 is provided with the second vibration damping member 90, the center of the second through hole 91 is different from the center of gravity of the second vibration damping member 90 when the second vibration damping member 90 is observed from above. It may be arranged in. When the suction pipe 18 and the discharge pipe 19 are connected to the compressor 40, the center of gravity of the compressor 40 moves in a direction different from the arrangement direction of the main body 41 and the suction muffler 43 in a plan view. By using the second vibration damping member 90, it is possible to suppress the noise generated by the movement of the center of gravity of the compressor 40.
　ここで、第１制振部材８０を上方から観察した際に第１貫通孔８１の中心が第１制振部材８０の重心と異なる位置に配置されている場合、吸入配管１８に対する第１制振部材８０の取り付け角度が限定される。このため、第１制振部材８０に切り込み８２を形成する場合、作業者が第１制振部材８０を押し出しながら第１貫通孔８１に吸入配管１８を入れることができる位置に、切り込み８２を形成することが好ましい。これにより、作業者は、吸入配管１８の向こう側に手を回さずに、第１制振部材８０を取り付けることができる。したがって、第１制振部材８０の取り付けが容易となる。 Here, when the first vibration damping member 80 is observed from above, if the center of the first through hole 81 is arranged at a position different from the center of gravity of the first vibration damping member 80, the first vibration damping member 18 with respect to the suction pipe 18 The mounting angle of the member 80 is limited. Therefore, when the notch 82 is formed in the first vibration damping member 80, the notch 82 is formed at a position where the operator can insert the suction pipe 18 into the first through hole 81 while pushing out the first vibration damping member 80. It is preferable to do so. As a result, the operator can attach the first vibration damping member 80 without turning his / her hand to the other side of the suction pipe 18. Therefore, the first vibration damping member 80 can be easily attached.
