　本発明は、以上のような課題を解決するためになされたもので、防音性能の低下を抑制しつつ、サービス性を向上させた室外機およびそれを備えた空気調和機を提供することを目的としている。 The present invention has been made to solve the above problems, and an object of the present invention is to provide an outdoor unit having improved serviceability and an air conditioner including the same while suppressing deterioration in soundproof performance. I am trying.
　本発明に係る室外機は、圧縮機と、前記圧縮機を覆う防音材と、を備え、前記防音材は、外側に設けられた第二部材と、前記第二部材の内側に設けられ前記第二部材よりも剛性の低い第一部材と、で構成され、前記圧縮機の側面を覆う側面部の下端の一部が切り欠かれることによって形成され、前記圧縮機に接続される配管が通るための切り欠き部を有し、前記切り欠き部において、前記第一部材の切り欠き範囲は、前記第二部材の切り欠き範囲よりも狭くなっているものである。 An outdoor unit according to the present invention comprises a compressor and a soundproof material covering the compressor, the soundproof material being a second member provided on the outside and the second member provided on the inside of the second member. A first member having a rigidity lower than that of two members, and is formed by cutting out a part of the lower end of the side surface portion that covers the side surface of the compressor, and a pipe connected to the compressor passes through. In the cutout portion, the cutout area of the first member is narrower than the cutout area of the second member.
　また、本発明に係る空気調和機は、上記の室外機と、室内機と、を備えたものである。 The air conditioner according to the present invention includes the above outdoor unit and indoor unit.
　本発明に係る室外機およびそれを備えた空気調和機によれば、防音材は、側面部の下端の一部が切り欠かれることによって形成され、圧縮機に接続される配管が通るための切り欠き部を有している。そのため、防音材の取り付け時は、防音材を圧縮機の上から被せるだけでよく、また、防音材の取り外し時は、防音材を上に持ち上げるだけでよい。その結果、室外機およびそれを備えた空気調和機のサービス性を向上させることができる。また、切り欠き部において、第一部材の切り欠き範囲は、第二部材の切り欠き範囲よりも狭くなっている。そのため、万が一、圧縮機に接続される配管が防音材に接触したとしても、第一部材のみが接触することになり、圧縮機の振動が防音材全体に伝わるのを抑制することができる。つまり、圧縮機の振動伝播を低減することができるため、防音性能の低下を抑制することができる。 According to the outdoor unit and the air conditioner provided with the outdoor unit of the present invention, the soundproof material is formed by cutting out a part of the lower end of the side surface portion, and a cut for passage of the pipe connected to the compressor. It has a notch. Therefore, when installing the soundproofing material, it is sufficient to cover it with the soundproofing material from above the compressor, and when removing the soundproofing material, simply lift it up. As a result, the serviceability of the outdoor unit and the air conditioner including the outdoor unit can be improved. Further, in the cutout portion, the cutout range of the first member is narrower than the cutout range of the second member. Therefore, even if the pipe connected to the compressor comes into contact with the soundproof material, only the first member comes into contact with the soundproof material, and it is possible to suppress the vibration of the compressor from being transmitted to the entire soundproof material. That is, since vibration propagation of the compressor can be reduced, it is possible to suppress deterioration of soundproof performance.

　図４は、本発明の実施の形態１に係る空気調和機の室外機１００に用いられる防音材３００を示す断面模式図である。図５は、本発明の実施の形態１に係る空気調和機の室外機１００に用いられる防音材３００を示す側面模式図である。
　図４に示すように、筐体１００ａの機械室１００ｃに収納されている圧縮機１は、低騒音化を図るために、防音材３００で覆われている。この防音材３００は、例えば円筒形状を有している。また、防音材３００は、防音および遮音効果がある剛性の高いゴムなどで構成され、外側に設けられた第二部材３２０と、吸音効果がある剛性の低いフェルトなどで構成され、内側に設けられた第一部材３１０とで構成されている。つまり、防音材３００は、第二部材３２０の内側に、第二部材３２０よりも剛性の低い第一部材３１０が設けられた二層構造を有している。また、この防音材３００は、圧縮機１の側面を覆う側面部３００ａと、圧縮機１の上面を覆う上面部３００ｂとで構成されている。 FIG. 4 is a schematic cross-sectional view showing the soundproof material 300 used in the outdoor unit 100 of the air-conditioning apparatus according to Embodiment 1 of the present invention. FIG. 5: is a side surface schematic diagram which shows the soundproofing material 300 used for the outdoor unit 100 of the air conditioner which concerns on Embodiment 1 of this invention.
As shown in FIG. 4, the compressor 1 housed in the machine room 100c of the housing 100a is covered with a soundproof material 300 in order to reduce noise. The soundproof material 300 has, for example, a cylindrical shape. Further, the soundproof material 300 is made of rubber or the like having a high rigidity that has a soundproofing and sound insulating effect, and is made of a second member 320 provided on the outer side and a felt having a low rigidity that has a sound absorbing effect, and is provided on the inner side. And the first member 310. That is, the soundproof material 300 has a two-layer structure in which the first member 310 having a lower rigidity than the second member 320 is provided inside the second member 320. The soundproof material 300 is composed of a side surface portion 300 a that covers the side surface of the compressor 1 and an upper surface portion 300 b that covers the upper surface of the compressor 1.
　この防音材３００の中に配置されている圧縮機１には配管１ａが接続されており、この配管１ａを防音材３００の外側にあるその他の部品と接続するために、図４および図５に示すように防音材３００の一部に切り欠き部４０１が設けられている。この切り欠き部４０１は、側面部３００ａの下端の一部が矩形状に切り欠かれることによって形成されており、圧縮機１の配管１ａは、この切り欠き部４０１を通って防音材３００の外側にあるその他の部品と接続されている。 A pipe 1a is connected to the compressor 1 arranged in the soundproofing material 300, and in order to connect the pipe 1a with other parts outside the soundproofing material 300, the piping 1a is connected to the compressor 1 shown in FIGS. As shown, a cutout portion 401 is provided in a part of the soundproof material 300. The cutout portion 401 is formed by cutting out a part of the lower end of the side surface portion 300a in a rectangular shape, and the pipe 1a of the compressor 1 passes through the cutout portion 401 and outside the soundproof material 300. Connected to other parts in.
　また、切り欠き部４０１は、圧縮機１の配管１ａとは接触しない位置および大きさに形成されているが、防音材３００の組み立てばらつき、あるいは防音材３００の経年劣化などによって、切り欠き部４０１が圧縮機１の配管１ａと接触してしまうことも考えられる。そこで、切り欠き部４０１において、第一部材３１０の切り欠き範囲は、第二部材３２０の切り欠き範囲よりも狭くなっている。そして、図５に示すように、第一部材３１０は切り欠き部４０１の各辺からはみ出しており、外部に露出している。 Further, the cutout portion 401 is formed at a position and a size that do not come into contact with the pipe 1a of the compressor 1, but the cutout portion 401 may be formed due to variations in assembly of the soundproof material 300, deterioration of the soundproof material 300 over time, or the like. May come into contact with the pipe 1a of the compressor 1. Therefore, in the cutout portion 401, the cutout range of the first member 310 is narrower than the cutout range of the second member 320. Then, as shown in FIG. 5, the first member 310 protrudes from each side of the cutout portion 401 and is exposed to the outside.
　このように、切り欠き部４０１において、第一部材３１０の切り欠き範囲を第二部材３２０の切り欠き範囲よりも狭くすることによって、切り欠き部４０１が圧縮機１の配管１ａと接触したとしても、接触するのが剛性の低い第一部材３１０のみとなる。そのため、圧縮機１の振動が第一部材３１０で吸収され、防音材３００に伝わるのを抑制することができる。つまり、圧縮機１の振動伝播を低減することができるため、防音性能を向上させることができる。 In this way, in the cutout portion 401, by making the cutout range of the first member 310 narrower than the cutout range of the second member 320, even if the cutout portion 401 comes into contact with the pipe 1a of the compressor 1. , Only the first member 310 having low rigidity contacts. Therefore, the vibration of the compressor 1 can be prevented from being absorbed by the first member 310 and being transmitted to the soundproof material 300. That is, since the vibration propagation of the compressor 1 can be reduced, the soundproof performance can be improved.
　図６は、振動数比と応答倍率との関係を示す図である。なお、図６の横軸は振動数比［ω／ωｎ］を示しており、縦軸は応答倍率、つまり振幅の大きさを示している。
　次に、上記の効果を、図６を用いて説明する。図６は、質量ｍ、ばね定数ｋ、および、ダッシュポットの減数係数ｃを用いた物理モデルの運動方程式の解を示す図である。図６に示すように、共振点である振動数比＝１においては、剛性が高く、減衰比ζが大きい方が応答倍率が小さい、つまり、伝達力が小さいことが分かる。この図６より、気泡が多く粘性があり、柔らかく剛性の低い部材は、振動伝達を低減できることが理解できる。騒音が振動エネルギーであると仮定すると、Ｃ／√（２ｍｋ）が１／４倍に低減する場合、３ｄＢ以上の効果を得ることができる。 FIG. 6 is a diagram showing the relationship between the frequency ratio and the response magnification. The horizontal axis of FIG. 6 represents the frequency ratio [ω/ω n ] and the vertical axis represents the response magnification, that is, the magnitude of the amplitude.
Next, the above effect will be described with reference to FIG. FIG. 6 is a diagram showing a solution of the equation of motion of the physical model using the mass m, the spring constant k, and the dashpot reduction coefficient c. As shown in FIG. 6, at the resonance frequency ratio=1, the higher the rigidity and the larger the damping ratio ζ, the smaller the response magnification, that is, the smaller the transmission force. From FIG. 6, it can be understood that a member having a large amount of bubbles, a high viscosity, a softness, and a low rigidity can reduce vibration transmission. Assuming that noise is vibrational energy, an effect of 3 dB or more can be obtained when C/√(2mk) is reduced by ¼.
　また、本実施の形態１では、防音材３００の側面部３００ａの下端の一部に切り欠き部４０１が設けられているため、防音材３００の防音材３００の取り付け時は、防音材３００を圧縮機１の上から被せるだけでよい。また、防音材３００の取り外し時は、防音材３００を上に持ち上げるだけでよい。その結果、室外機１００およびそれを備えた空気調和機のサービス性を向上させることができる。 Further, in the first embodiment, since the notch 401 is provided at a part of the lower end of the side surface portion 300a of the soundproof material 300, the soundproof material 300 is compressed when the soundproof material 300 is attached. All you have to do is cover it from above the machine 1. Further, when removing the soundproof material 300, it suffices to lift the soundproof material 300 upward. As a result, the serviceability of the outdoor unit 100 and the air conditioner including the outdoor unit 100 can be improved.
　なお、本実施の形態１では、切り欠き部４０１は、側面部３００ａの下端の一部が矩形状に切り欠かれることによって形成されているとしたが、それに限定されず、どのような形状に切り欠かれていてもよい。 In the first embodiment, the cutout portion 401 is formed by cutting a part of the lower end of the side surface portion 300a into a rectangular shape, but the shape is not limited thereto, and any shape is possible. It may be cut out.
　また、切り欠き部４０１において、第二部材３２０の各辺が第一部材３１０で覆われるように構成されてもよく、そのような構成とすることで、剛性の高い第二部材３２０が圧縮機１の配管１ａに接触するのをより確実に防ぐことができる。 Further, in the cutout portion 401, each side of the second member 320 may be configured to be covered with the first member 310. With such a configuration, the second member 320 having high rigidity is compressed by the compressor. The contact with the first pipe 1a can be more reliably prevented.
　以上、本実施の形態１に係る室外機１００は、圧縮機１と、圧縮機１を覆う防音材３００と、を備えている。また、防音材３００は、外側に設けられた第二部材３２０と、第二部材３２０の内側に設けられ第二部材３２０よりも剛性の低い第一部材３１０と、で構成されている。また、防音材３００は、圧縮機１の側面を覆う側面部３００ａの下端の一部が切り欠かれることによって形成され、圧縮機１に接続される配管１ａが通るための切り欠き部４０１を有している。そして、切り欠き部４０１において、第一部材３１０の切り欠き範囲は、第二部材３２０の切り欠き範囲よりも狭くなっているものである。 As described above, the outdoor unit 100 according to the first embodiment includes the compressor 1 and the soundproof material 300 that covers the compressor 1. Further, the soundproof material 300 includes a second member 320 provided outside and a first member 310 provided inside the second member 320 and having a rigidity lower than that of the second member 320. Further, the soundproof material 300 is formed by cutting out a part of the lower end of the side surface portion 300 a that covers the side surface of the compressor 1, and has a cutout portion 401 through which the pipe 1 a connected to the compressor 1 passes. doing. Then, in the cutout portion 401, the cutout range of the first member 310 is narrower than the cutout range of the second member 320.
　また、本実施の形態１に係る空気調和機は、上記の室外機１００と、室内機２００と、を備えたものである。 Further, the air conditioner according to Embodiment 1 includes the outdoor unit 100 and the indoor unit 200 described above.
　本実施の形態１に係る室外機１００およびそれを備えた空気調和機によれば、防音材３００は、側面部３００ａの下端の一部が切り欠かれることによって形成され、圧縮機１に接続される配管１ａが通るための切り欠き部４０１を有している。そのため、防音材３００の防音材３００の取り付け時は、防音材３００を圧縮機１の上から被せるだけでよく、また、防音材３００の取り外し時は、防音材３００を上に持ち上げるだけでよい。その結果、室外機１００およびそれを備えた空気調和機のサービス性を向上させることができる。また、切り欠き部４０１において、第一部材３１０の切り欠き範囲は、第二部材３２０の切り欠き範囲よりも狭くなっている。そのため、万が一、圧縮機１に接続される配管１ａが防音材３００に接触したとしても、第一部材３１０のみが接触することになり、圧縮機１の振動が防音材３００全体に伝わるのを抑制することができる。つまり、圧縮機１の振動伝播を低減することができるため、防音性能の低下を抑制することができる。 According to the outdoor unit 100 and the air conditioner including the same according to the first embodiment, the soundproofing material 300 is formed by cutting out a part of the lower end of the side surface portion 300a and is connected to the compressor 1. It has a notch 401 for passing the pipe 1a. Therefore, when the soundproof material 300 is attached, the soundproof material 300 only needs to be covered from above the compressor 1, and when the soundproof material 300 is removed, the soundproof material 300 need only be lifted up. As a result, the serviceability of the outdoor unit 100 and the air conditioner including the outdoor unit 100 can be improved. Further, in the cutout portion 401, the cutout range of the first member 310 is narrower than the cutout range of the second member 320. Therefore, even if the pipe 1a connected to the compressor 1 comes into contact with the soundproof material 300, only the first member 310 comes into contact with the soundproof material 300, and the vibration of the compressor 1 is prevented from being transmitted to the entire soundproof material 300. can do. That is, since the vibration propagation of the compressor 1 can be reduced, it is possible to suppress the deterioration of the soundproof performance.

Like the first member 310, the third member 311 is made of felt or the like having a sound absorbing effect and low rigidity. The third member 311 may have a configuration in which it is connected to the first member 310 as a separate body, or may be integrally molded with the first member 310.
　このように、切り欠き部４０１に第三部材３１１を設けることで、防音材３００の切り欠き部４０１での開口面積が減り、その開口から騒音が漏れるのを抑制することができる。その結果、本実施の形態２に係る防音材３００によって、室外機１００およびそれを備えた空気調和機のサービス性を向上させるとともに、遮音効果を高めることができる。 In this way, by providing the third member 311 in the cutout portion 401, the opening area of the soundproofing material 300 in the cutout portion 401 can be reduced, and it is possible to prevent noise from leaking from the opening.

The contact with the first pipe 1a can be more reliably prevented.
　また、第三部材３１１を上側に弧形状を有する半円形状のように丸みを有した形状にしたり、第三部材３１１を曲がりやすくなる厚みにしたりすることで、第二部材３２０と圧縮機１の配管１ａとが直接接触しづらくなり、それらが接触するのを抑制することができる。 In addition, the third member 311 has a rounded shape such as a semicircular shape having an arc shape on the upper side, or the third member 311 has a thickness that makes it easy to bend, so that the second member 320 and the compressor 1 are provided. It becomes difficult to make direct contact with the pipe 1a, and it is possible to prevent them from contacting each other.
　なお、第三部材３１１を切り欠き部４０１に設けるのではなく、第三部材３１１を圧縮機１の配管１ａに直接設けてもよい。 Note that instead of providing the third member 311 in the cutout portion 401, the third member 311 may be directly provided in the pipe 1a of the compressor 1.
　以上、本実施の形態２に係る室外機１００において、切り欠き部４０１は、第二部材３２０よりも剛性の低い第三部材３１１で覆われており、第三部材３１１には、配管１ａが通るためのスリット３１２が形成されている。 As described above, in the outdoor unit 100 according to the second embodiment, the cutout portion 401 is covered with the third member 311 having lower rigidity than the second member 320, and the pipe 1a passes through the third member 311. A slit 312 for forming is formed.

The plurality of slits 312 are formed at positions displaced in the horizontal direction, the vertical direction, or the horizontal direction and the vertical direction, respectively, and different pipes 1 a can pass through the respective slits 312. Like the first member 310, the third member 311 is made of felt or the like having a sound absorbing effect and low rigidity. The third member 311 may have a configuration in which it is connected to the first member 310 as a separate body, or may be integrally molded with the first member 310.
　このように、第三部材３１１にスリット３１２を複数形成することで、圧縮機１に接続される配管１ａが互いに近い位置に複数配置されている場合でも、１つの切り欠き部４０１内に複数の配管１ａを通すことができる。 As described above, by forming the plurality of slits 312 in the third member 311, even when the plurality of pipes 1a connected to the compressor 1 are arranged at positions close to each other, the plurality of slits 312 are formed in one cutout portion 401. The pipe 1a can be passed through.
　なお、複数の配管１ａが互いに離れた位置に配置されている場合は、切り欠き部４０１を複数設け、各切り欠き部４０１にスリット３１２が形成された第三部材３１１を設ける構成とするとよい。そうすることで、複数の配管１ａが互いに離れた位置に配置されている場合でも、各配管１ａを切り欠き部４０１内に通すことができる。 When a plurality of pipes 1a are arranged at positions distant from each other, a plurality of cutouts 401 may be provided, and a third member 311 having a slit 312 formed in each cutout 401 may be provided.

When a plurality of pipes 1a are arranged in the horizontal direction, the slits 312 connected in the horizontal direction are formed. It should be noted that although the plurality of pipes 1a are arranged close to each other, if the pipes 1a are displaced in the horizontal direction or the vertical direction, slits 312 may be provided in accordance with the positions of the respective pipes 1a, or the pipe diameters of the plurality of pipes 1a may be different. If different, the size of the slit 312 is changed according to the tube diameter.
　そうすることで、防音材３００の防音材３００の取り付け時は、防音材３００を圧縮機１の上から被せるだけでよく、また、防音材３００の取り外し時は、防音材３００を上に持ち上げるだけでよい。その結果、室外機１００およびそれを備えた空気調和機のサービス性を向上させることができる。 By doing so, when installing the soundproof material 300 of the soundproof material 300, it suffices to cover the soundproof material 300 from above the compressor 1, and when removing the soundproof material 300, simply lift the soundproof material 300 upward.

　本実施の形態３に係る室外機１００によれば、第三部材３１１にスリット３１２が複数形成されているため、圧縮機１に接続される配管１ａが互いに近い位置に複数配置されている場合でも、１つの切り欠き部４０１内に複数の配管１ａを通すことができる。 According to the outdoor unit 100 of the third embodiment, since the plurality of slits 312 are formed in the third member 311, even when the plurality of pipes 1a connected to the compressor 1 are arranged at positions close to each other.

　図９は、本発明の実施の形態４に係る空気調和機の室外機１００に用いられる防音材３００を示す断面模式図である。
　図９に示すように、本実施の形態４に係る防音材３００は、第二部材３２０の外面の一部に第四部材４０２が設けられている。この第四部材４０２は、第一部材３１０と同様に、吸音効果がある剛性の低いフェルトなどで構成されている。この第四部材４０２は、圧縮機１に接続される配管１ａまたはセパレータ１１０などのその他の構造物が第二部材３２０と接触しそうな位置に設けられている。 FIG. 9: is a cross-sectional schematic diagram which shows the soundproof material 300 used for the outdoor unit 100 of the air conditioner which concerns on Embodiment 4 of this invention.
As shown in FIG. 9, in the soundproof material 300 according to the fourth embodiment, the fourth member 402 is provided on a part of the outer surface of the second member 320. Like the first member 310, the fourth member 402 is made of felt or the like having a sound absorbing effect and low rigidity. The fourth member 402 is provided at a position where the pipe 1a connected to the compressor 1 or another structure such as the separator 110 may come into contact with the second member 320.
　このように、第二部材３２０の外面の一部に第四部材４０２を設けることで、配管１ａまたはその他の構造物が、第二部材３２０と直接接触するのを回避することができる。また、配管１ａまたはその他の構造物が防音材３００と接触したとしても、第二部材３２０よりも剛性の低い第四部材４０２と接触することになるため、圧縮機１の振動がそれらに伝播しにくくなり、防音効果を高めることができる。 By thus providing the fourth member 402 on a part of the outer surface of the second member 320, it is possible to avoid the pipe 1a or another structure from directly contacting the second member 320. Further, even if the pipe 1a or other structure comes into contact with the soundproof material 300, it comes into contact with the fourth member 402 having a rigidity lower than that of the second member 320, so that the vibration of the compressor 1 propagates to them. It becomes difficult and the soundproof effect can be enhanced.
　以上、本実施の形態４に係る室外機１００において、防音材３００の第二部材３２０の外面の少なくとも一部に、第二部材３２０よりも剛性の低い第四部材４０２が設けられている。 As described above, in the outdoor unit 100 according to the fourth embodiment, the fourth member 402 having lower rigidity than the second member 320 is provided on at least a part of the outer surface of the second member 320 of the soundproof material 300.

Therefore, it is possible to avoid the pipe 1a or other structures from directly contacting the second member 320. Further, even if the pipe 1a or other structure comes into contact with the soundproof material 300, it comes into contact with the fourth member 402 having a rigidity lower than that of the second member 320, so that the vibration of the compressor 1 propagates to them. It becomes difficult and the soundproof effect can be enhanced.
　実施の形態５．
　以下、本発明の実施の形態５について説明するが、実施の形態１～４と重複するものについては説明を省略し、実施の形態１～４と同じ部分または相当する部分には同じ符号を付す。 Embodiment 5.
Hereinafter, the fifth embodiment of the present invention will be described. However, the description of the same parts as those of the first to fourth embodiments will be omitted, and the same or corresponding parts to those of the first to fourth embodiments will be designated by the same reference numerals. ..
　図１０は、本発明の実施の形態５に係る空気調和機の室外機１００に用いられる防音材３００を示す断面模式図である。図１１は、本発明の実施の形態５に係る空気調和機の室外機１００に用いられる防音材３００を平面視した模式図である。 FIG. 10 is a schematic cross-sectional view showing a soundproof material 300 used in the outdoor unit 100 of the air conditioner according to Embodiment 5 of the present invention.

The slit 403 is formed at a position where the pipe 1 a or other structure connected to the compressor 1 is likely to come into contact with the second member 320.
　このように、第二部材３２０の外面の一部にスリット４０３を形成することで、第二部材３２０のスリット４０３が形成された箇所での剛性が低くなる。そのため、配管１ａまたはその他の構造物が、第二部材３２０と接触した際の第二部材３２０の変形を大きくすることができる。そして、そうすることで、圧縮機１の振動がそれらに伝播しにくくなり、防音効果を高めることができる。また、追加の部材などを必要としないため、低コストで防音効果を高めることができる。 By thus forming the slit 403 on a part of the outer surface of the second member 320, the rigidity of the portion of the second member 320 where the slit 403 is formed becomes low. Therefore, the deformation of the second member 320 when the pipe 1a or another structure contacts the second member 320 can be increased. Then, by doing so, the vibration of the compressor 1 is less likely to propagate to them, and the soundproof effect can be enhanced. Further, since no additional member is required, the soundproof effect can be enhanced at low cost.
　なお、本実施の形態５に係る防音材３００では、スリット４０３が２箇所に設けられているが、それに限定されず、１箇所でもよいし３箇所以上でもよい。また、スリット４０３の形状は、例えば直線形状など、配管１ａまたはその他の構造物が、第二部材３２０と接触した際の第二部材３２０の変形を大きくすることができる形状であれば何でもよい。また、スリット４０３の長さに関しても、第二部材３２０と接触した際の第二部材３２０の変形を大きくすることができる長さであればよい In the soundproofing material 300 according to the fifth embodiment, the slits 403 are provided at two places, but it is not limited to that and may be one place or three or more places. Further, the shape of the slit 403 may be any shape, such as a linear shape, as long as the deformation of the second member 320 when the pipe 1a or other structure comes into contact with the second member 320 can be increased. Further, regarding the length of the slit 403, any length may be used as long as it can increase the deformation of the second member 320 when coming into contact with the second member 320.
　以上、本実施の形態５に係る室外機１００において、防音材３００の第二部材３２０の外面の少なくとも一部にスリット４０３が形成されている。 As described above, in the outdoor unit 100 according to the fifth embodiment, the slit 403 is formed on at least a part of the outer surface of the second member 320 of the soundproof material 300.
