For example, the insertion portion 57 is press-fitted into the opening 18 by being inserted into the opening 18 and attached to the housing 11 . By attaching the insertion portion 57 to the housing 11 , the communication unit 50 is attached to the side wall portion 11 c of the housing 11 from the outside.
　実施の形態１において接続端子５８は、筒状の差込部５７の内部に位置する。接続端子５８は、差込部５７の幅方向他方側（－Ｙ側）の開口を介して通信ユニット５０の外部に露出している。接続端子５８は、差込部５７とともに開口部１８に挿入されて、機械室１１ｂの内部に配置される。実施の形態１において差込部５７および接続端子５８は、制御部１７の制御基板１７ａよりも下方に位置する。接続端子５８は、ケース５１内に収容された信号変換部５２に電気的に接続されている。 In Embodiment 1, the connection terminal 58 is positioned inside the tubular insertion portion 57 . The connection terminal 58 is exposed to the outside of the communication unit 50 through an opening on the other widthwise side (−Y side) of the insertion portion 57 . The connection terminal 58 is inserted into the opening 18 together with the insertion portion 57 and arranged inside the machine chamber 11b. In Embodiment 1, the insertion portion 57 and the connection terminal 58 are located below the control board 17 a of the control portion 17 . The connection terminal 58 is electrically connected to the signal converter 52 housed in the case 51 .
　室外機１０は、制御部１７と接続端子５８とを繋ぐ配線部材６０を備える。配線部材６０によって、接続端子５８は、筐体１１内において制御部１７に電気的に接続されている。これにより、制御部１７が配線部材６０および接続端子５８を介して信号変換部５２に電気的に接続されている。実施の形態１において配線部材６０は、両端にそれぞれコネクタ６１，６２が取り付けられたリード線である。コネクタ６１は、制御基板１７ａに接続されている。コネクタ６２は、接続端子５８に幅方向他方側（－Ｙ側）から接続されている。通信ユニット５０を取り付ける作業者は、差込部５７を開口部１８に差し込んで通信ユニット５０を筐体１１に取り付けた後に、配線部材６０によって制御部１７と接続端子５８とを接続する。このとき、配線部材６０は、コネクタ６１を介して予め制御基板１７ａに取り付けられた状態となっていてもよい。 The outdoor unit 10 has a wiring member 60 that connects the control unit 17 and the connection terminal 58 . The connection terminal 58 is electrically connected to the controller 17 inside the housing 11 by the wiring member 60 . Thereby, the control section 17 is electrically connected to the signal conversion section 52 via the wiring member 60 and the connection terminal 58 . In Embodiment 1, the wiring member 60 is a lead wire with connectors 61 and 62 attached to both ends thereof. The connector 61 is connected to the control board 17a.

　実施の形態１によれば、通信ユニット５０が室外機１０の筐体１１に取り付けられ、制御部１７と通信ユニット５０の接続端子５８とは、筐体１１内で接続される。そのため、制御部１７と通信ユニット５０とを繋ぐ電気通信路が室外機１０の外部に露出しない。これにより、制御部１７と通信ユニット５０とを筐体１１の外部で接続する外部ケーブルは不要となり、外部ケーブルが断線するなどの不具合が生じることがない。したがって、制御部１７と通信ユニット５０との接続が切断されることを抑制できる。そのため、通信ユニット５０の通信不良が生じることを抑制できる。また、外部ケーブルを設ける必要がない分、室外機１０の製造コストを低減できる。また、外部ケーブルを接続する作業を行う必要がなく、通信ユニット５０の取付作業を容易にできる。 According to Embodiment 1, the communication unit 50 is attached to the housing 11 of the outdoor unit 10 , and the control section 17 and the connection terminal 58 of the communication unit 50 are connected within the housing 11 . Therefore, the electrical communication path connecting the control unit 17 and the communication unit 50 is not exposed to the outside of the outdoor unit 10 . This eliminates the need for an external cable for connecting the control unit 17 and the communication unit 50 outside the housing 11, thus preventing problems such as disconnection of the external cable. Therefore, disconnection between the control unit 17 and the communication unit 50 can be suppressed. Therefore, it is possible to suppress the occurrence of communication failure of the communication unit 50 . Moreover, the manufacturing cost of the outdoor unit 10 can be reduced by the amount of no need to provide an external cable. In addition, there is no need to perform work for connecting an external cable, and the mounting work of the communication unit 50 can be facilitated.
　また、制御部１７から信号変換部５２に至る電気通信路を、室外機１０の筐体１１および通信ユニット５０内に収納できる。そのため、制御部１７から信号変換部５２に送信される電気信号に室外機１０の外部からの外来ノイズが乗ることを抑制できる。これにより、通信ユニット５０による通信品質を向上できる。また、制御部１７による通信ユニット５０の誤制御を抑制できる。 Also, the electrical communication path from the control unit 17 to the signal conversion unit 52 can be accommodated in the housing 11 of the outdoor unit 10 and the communication unit 50. Therefore, it is possible to prevent external noise from outside the outdoor unit 10 from being added to the electric signal transmitted from the control unit 17 to the signal conversion unit 52 . Thereby, the communication quality of the communication unit 50 can be improved. In addition, erroneous control of the communication unit 50 by the control section 17 can be suppressed.
　また、実施の形態１によれば、筐体１１は、開口部１８を有する。通信ユニット５０は、開口部１８に差し込まれる差込部５７を有する。接続端子５８は、差込部５７に設けられている。そのため、差込部５７を開口部１８に差し込むことで、接続端子５８を筐体１１の内部に挿入できる。これにより、開口部１８を介して、通信ユニット５０を筐体１１に容易に後付けできる。 Further, according to Embodiment 1, the housing 11 has the opening 18 . The communication unit 50 has an insertion portion 57 that is inserted into the opening 18 . The connection terminal 58 is provided on the insertion portion 57 . Therefore, by inserting the insertion portion 57 into the opening 18 , the connection terminal 58 can be inserted inside the housing 11 . Thereby, the communication unit 50 can be easily retrofitted to the housing 11 through the opening 18 .
　また、実施の形態１によれば、通信ユニット５０は、室外機１０の筐体１１の外部に配置される本体部５６を有する。差込部５７は、本体部５６から突出して開口部１８に差し込まれている。送受信部５３は、本体部５６に設けられている。そのため、室外機１０の筐体１１を金属製としても、筐体１１が通信ユニット５０の送受信部５３から放射される電波の妨げとならない。そのため、通信ユニット５０から基地局ＢＳへのデータ送信を好適に行うことができる。 Further, according to Embodiment 1, the communication unit 50 has the main body portion 56 arranged outside the housing 11 of the outdoor unit 10 . The insertion portion 57 protrudes from the body portion 56 and is inserted into the opening portion 18 . The transmitting/receiving section 53 is provided in the body section 56 . Therefore, even if the housing 11 of the outdoor unit 10 is made of metal, the housing 11 does not interfere with radio waves radiated from the transmitting/receiving section 53 of the communication unit 50 . Therefore, data transmission from the communication unit 50 to the base station BS can be performed favorably.
　また、実施の形態１によれば、差込部５７は、接続端子５８を囲む筒状である。そのため、差込部５７によって接続端子５８を保護できる。これにより、差込部５７を開口部１８に差し込む際に、接続端子５８が筐体１１に接触して損傷するなどの不具合が生じることを抑制できる。したがって、制御部１７と通信ユニット５０との接続に不具合が生じることを抑制できる。そのため、通信ユニット５０の通信不良が生じることをより抑制できる。また、制御部１７から信号変換部５２に至る電気通信路の一部を差込部５７によって囲んで覆うことができる。そのため、制御部１７から信号変換部５２に送信される電気信号に室外機１０の外部からの外来ノイズが乗ることをより抑制できる。これにより、通信ユニット５０による通信品質をより向上できる。 Further, according to Embodiment 1, the insertion portion 57 has a tubular shape surrounding the connection terminal 58 . Therefore, the connection terminal 58 can be protected by the insertion portion 57 . As a result, when inserting the insertion portion 57 into the opening 18 , it is possible to prevent the connection terminal 58 from contacting the housing 11 and being damaged. Therefore, it is possible to prevent a problem from occurring in the connection between the control section 17 and the communication unit 50 . Therefore, it is possible to further suppress the occurrence of communication failure of the communication unit 50 . Also, a part of the electrical communication path from the control unit 17 to the signal conversion unit 52 can be surrounded and covered by the insertion unit 57 . Therefore, it is possible to further suppress external noise from the outside of the outdoor unit 10 on the electric signal transmitted from the control unit 17 to the signal conversion unit 52 . Thereby, the communication quality of the communication unit 50 can be further improved.
　また、実施の形態１によれば、差込部５７は、開口部１８に差し込まれることで筐体１１に取り付けられる取付部である。そのため、通信ユニット５０を筐体１１に取り付ける作業者は、差込部５７を開口部１８に差し込むことで、通信ユニット５０を容易に筐体１１に取り付けることができる。 Further, according to Embodiment 1, the insertion portion 57 is an attachment portion that is attached to the housing 11 by being inserted into the opening portion 18 . Therefore, a worker who attaches the communication unit 50 to the housing 11 can easily attach the communication unit 50 to the housing 11 by inserting the insertion portion 57 into the opening 18 .
　また、実施の形態１によれば、開口部１８は、ノックアウト穴である。そのため、通信ユニット５０が取り付けられる前の筐体１１には、開口部１８が形成されていない。これにより、通信ユニット５０が取り付けられる前の筐体１１内に、雨や埃などの異物が侵入することを抑制できる。 Further, according to Embodiment 1, the opening 18 is a knockout hole. Therefore, the opening 18 is not formed in the housing 11 before the communication unit 50 is attached. As a result, foreign matter such as rain or dust can be prevented from entering the housing 11 before the communication unit 50 is attached.
　また、実施の形態１によれば、室外機１０は、制御部１７と接続端子５８とを繋ぐ配線部材６０を備える。配線部材６０は、接続端子５８と接続されるコネクタ６２を有する。そのため、通信ユニット５０を取り付ける作業者は、差込部５７を開口部１８に差し込んだ後に、筐体１１の内部でコネクタ６２を接続端子５８に接続することで、制御部１７と通信ユニット５０とを容易に電気的に接続できる。 Also, according to Embodiment 1, the outdoor unit 10 includes the wiring member 60 that connects the control unit 17 and the connection terminal 58 . The wiring member 60 has a connector 62 connected to the connection terminal 58 . Therefore, an operator who installs the communication unit 50 inserts the insertion portion 57 into the opening portion 18 and then connects the connector 62 to the connection terminal 58 inside the housing 11, thereby connecting the control portion 17 and the communication unit 50 together. can be easily electrically connected.
　また、実施の形態１によれば、制御部１７は、信号形式を変換せずに信号変換部５２に電気信号を送信する。そのため、制御部１７に電気信号の信号形式を変換する変換部を設ける必要がない。これにより、室外機１０の部品点数を低減でき、室外機１０の製造コストを低減できる。ここで、上述したように、実施の形態１では、制御部１７から信号変換部５２に送信される電気信号に室外機１０の外部からの外来ノイズが乗ることを抑制できる。そのため、制御部１７から信号変換部５２へ電気信号を送信する際に、電気信号をノイズが乗り難い信号形式に変換する必要がない。したがって、制御部１７が信号形式を変換しなくても、信号変換部５２に送られる電気信号にノイズが乗ることが抑制される。 Also, according to Embodiment 1, the control unit 17 transmits the electrical signal to the signal conversion unit 52 without converting the signal format. Therefore, it is not necessary to provide a conversion section for converting the signal format of the electric signal in the control section 17 . Thereby, the number of parts of the outdoor unit 10 can be reduced, and the manufacturing cost of the outdoor unit 10 can be reduced. Here, as described above, in Embodiment 1, it is possible to prevent external noise from outside the outdoor unit 10 from being added to the electrical signal transmitted from the control unit 17 to the signal conversion unit 52 . Therefore, when an electrical signal is transmitted from the control section 17 to the signal conversion section 52, it is not necessary to convert the electrical signal into a signal format in which noise is less likely to occur. Therefore, even if the control unit 17 does not convert the signal format, the electrical signal sent to the signal conversion unit 52 is suppressed from being contaminated with noise.

The end of the wiring member 260 opposite to the side where the connector 262 is provided is directly connected to the control board 217a by, for example, soldering. When the connector 262 is held by the holding portion 217b, the entire wiring member 260 overlaps the control board 217a when viewed in the front-rear direction.
　通信ユニット２５０を取り付ける作業者は、通信ユニット２５０の差込部５７を開口部１８に差し込んだ後に、コネクタ２６２を保持部２１７ｂから取り外して、配線部材２６０を制御部２１７から引き出す。作業者は、引き出した配線部材２６０のコネクタ２６２を、図７において実線で示すように、接続端子５８に接続する。なお、制御部２１７が制御基板２１７ａを収容するケースを有する場合には、当該ケース内に配線部材２６０が収容されて保持されていてもよい。 After inserting the insertion portion 57 of the communication unit 250 into the opening 18 , the worker who installs the communication unit 250 removes the connector 262 from the holding portion 217 b and pulls out the wiring member 260 from the control portion 217 . The worker connects the connector 262 of the wiring member 260 pulled out to the connection terminal 58 as indicated by the solid line in FIG. In addition, when the control unit 217 has a case that accommodates the control board 217a, the wiring member 260 may be accommodated and held in the case.
　実施の形態２において通信ユニット２５０の差込部５７には、筐体１１の壁部に内側から引っ掛けられる爪部２５９が設けられている。爪部２５９は、差込部５７の外周面から、差込部５７の径方向外側に突出している。爪部２５９の突出高さは、本体部５６から離れるに従って小さくなっている。爪部２５９は、差込部５７の径方向に弾性変形可能である。差込部５７が開口部１８に幅方向一方側（＋Ｙ側）から差し込まれる途中において爪部２５９は、開口部１８の内周面から押されて弾性変形する。差込部５７が開口部１８に奥まで差し込まれると、爪部２５９の全体が筐体１１内に挿入され、爪部２５９が復元変形する。これにより、爪部２５９が側壁部１１ｃのうち開口部１８の周縁部に筐体１１の内側から引っ掛けられる。このように、実施の形態２において差込部５７は、爪部２５９を用いたスナップフィットによって筐体１１に固定されている。爪部２５９は、差込部５７の周方向に沿って複数設けられている。なお、実施の形態２において差込部５７は、開口部１８に圧入されなくてもよく、開口部１８に隙間嵌めされてもよい。 In the second embodiment, the insertion portion 57 of the communication unit 250 is provided with a claw portion 259 that is hooked on the wall portion of the housing 11 from the inside. The claw portion 259 protrudes radially outward of the insertion portion 57 from the outer peripheral surface of the insertion portion 57 . The protruding height of the claw portion 259 decreases with increasing distance from the body portion 56 . The claw portion 259 is elastically deformable in the radial direction of the insertion portion 57 . While the insertion portion 57 is being inserted into the opening 18 from one side in the width direction (+Y side), the claw portion 259 is pushed from the inner peripheral surface of the opening 18 and elastically deformed. When the insertion portion 57 is fully inserted into the opening 18, the entire claw portion 259 is inserted into the housing 11, and the claw portion 259 is restored and deformed. As a result, the claw portion 259 is hooked on the peripheral portion of the opening 18 of the side wall portion 11 c from the inside of the housing 11 . As described above, in the second embodiment, the insertion portion 57 is fixed to the housing 11 by snap-fitting using the claw portion 259 . A plurality of claw portions 259 are provided along the circumferential direction of the insertion portion 57 . In addition, in Embodiment 2, the insertion portion 57 may not be press-fitted into the opening portion 18 and may be loosely fitted into the opening portion 18 .
　室外機２１０のその他の構成は、実施の形態１の室外機１０のその他の構成と同様にできる。空気調和装置２００のその他の構成は、実施の形態１の空気調和装置１００のその他の構成と同様にできる。 Other configurations of the outdoor unit 210 can be the same as other configurations of the outdoor unit 10 of the first embodiment. Other configurations of the air conditioner 200 can be the same as other configurations of the air conditioner 100 of the first embodiment.
　実施の形態２によれば、制御部２１７は、接続端子５８に接続されるコネクタ２６２を保持可能な保持部２１７ｂを有する。そのため、通信ユニット２５０を取り付ける前において、コネクタ２６２を保持部２１７ｂに保持させて、配線部材２６０を制御部２１７に好適に保持できる。これにより、通信ユニット２５０を取り付ける前において、配線部材２６０が筐体１１内で動くことを抑制できる。したがって、配線部材２６０を予め筐体１１内の制御部２１７に接続しておく場合であっても、配線部材２６０が他の部品と擦れるなどして損傷することを抑制できる。また、通信ユニット２５０を取り付ける際においては、コネクタ２６２を保持部２１７ｂから外して接続端子５８に接続することで、制御部２１７と通信ユニット２５０とを容易に電気的に接続できる。そのため、制御部２１７と通信ユニット２５０との接続作業を容易にできる。 According to Embodiment 2, the control section 217 has a holding section 217b capable of holding the connector 262 connected to the connection terminal 58. Therefore, before the communication unit 250 is attached, the connector 262 is held by the holding portion 217b so that the wiring member 260 can be preferably held by the control portion 217 . This can prevent the wiring member 260 from moving within the housing 11 before the communication unit 250 is attached. Therefore, even if the wiring member 260 is connected in advance to the control unit 217 inside the housing 11, it is possible to prevent the wiring member 260 from being damaged by rubbing against other components. Further, when attaching the communication unit 250, the connector 262 is removed from the holding portion 217b and connected to the connection terminal 58, whereby the control portion 217 and the communication unit 250 can be easily electrically connected. Therefore, the connection work between the control unit 217 and the communication unit 250 can be facilitated.
　また、実施の形態２によれば、差込部５７には、筐体１１の壁部に内側から引っ掛けられる爪部２５９が設けられている。そのため、爪部２５９によって、差込部５７が開口部１８から抜けることを好適に抑制できる。これにより、差込部５７を開口部１８に差し込むことで、より安定して通信ユニット２５０を筐体１１に取り付けることができる。したがって、通信ユニット２５０が筐体１１から脱落することを好適に抑制できる。 Further, according to the second embodiment, the insertion portion 57 is provided with a claw portion 259 that is hooked on the wall portion of the housing 11 from the inside. Therefore, the claw portion 259 can suitably prevent the insertion portion 57 from slipping out of the opening portion 18 . Accordingly, by inserting the insertion portion 57 into the opening 18, the communication unit 250 can be attached to the housing 11 more stably. Therefore, it is possible to preferably prevent the communication unit 250 from falling off from the housing 11 .

　図８に示すように、実施の形態３の空気調和装置３００の室外機３１０において、配線部材３６０のコネクタ３６２は、制御部１７に固定されている。より詳細には、コネクタ３６２は、制御基板１７ａの下側部分に固定されている。コネクタ３６２は、開口部１８と幅方向（左右方向）に対向する位置に配置されている。コネクタ３６２は、幅方向一方側（＋Ｙ側）を向いた状態で制御部１７に固定されている。コネクタ３６２には、開口部１８に差し込まれた差込部５７に設けられた接続端子５８が幅方向一方側から接続されている。 As shown in FIG. 8 , in the outdoor unit 310 of the air conditioner 300 of Embodiment 3, the connector 362 of the wiring member 360 is fixed to the control section 17 . More specifically, connector 362 is fixed to the lower portion of control board 17a. The connector 362 is arranged at a position facing the opening 18 in the width direction (horizontal direction). The connector 362 is fixed to the control unit 17 while facing one width direction side (+Y side). A connection terminal 58 provided in an insertion portion 57 inserted into the opening portion 18 is connected to the connector 362 from one side in the width direction.
　室外機３１０のその他の構成は、上述した各実施の形態における室外機のその他の構成と同様にできる。空気調和装置３００のその他の構成は、上述した各実施の形態における空気調和装置のその他の構成と同様にできる。 Other configurations of the outdoor unit 310 can be the same as other configurations of the outdoor units in each of the above-described embodiments. Other configurations of the air conditioner 300 can be the same as other configurations of the air conditioners in each of the above-described embodiments.
　実施の形態３によれば、配線部材３６０のコネクタ３６２は、制御部１７に固定され、かつ、開口部１８に対向する位置に配置されている。そのため、差込部５７を開口部１８に差し込むことで、差込部５７に設けられた接続端子５８をコネクタ３６２に接続することができる。これにより、手作業で配線部材３６０のコネクタ３６２を接続端子５８に接続する作業を別途行う必要がない。したがって、通信ユニット５０の取付作業を容易にできる。また、コネクタ３６２の向きを誤って接続端子５８に接続するなどの誤接続が生じることを抑制できる。 According to Embodiment 3, the connector 362 of the wiring member 360 is fixed to the control section 17 and arranged at a position facing the opening section 18 . Therefore, by inserting the insertion portion 57 into the opening 18 , the connection terminal 58 provided in the insertion portion 57 can be connected to the connector 362 . As a result, it is not necessary to manually connect the connector 362 of the wiring member 360 to the connection terminal 58 separately. Therefore, the mounting work of the communication unit 50 can be facilitated. In addition, it is possible to prevent erroneous connection, such as connecting the connector 362 to the connection terminal 58 in the wrong direction.
　実施の形態４．
　図９は、実施の形態４における室外機４１０の一部を前方から見た部分断面図である。なお、以下の説明において、上述した実施の形態と同様の構成については、適宜同一の符号を付す等により説明を省略する場合がある。 Embodiment 4.
FIG. 9 is a partial cross-sectional view of part of the outdoor unit 410 according to Embodiment 4 as seen from the front. It should be noted that, in the following description, the same configurations as those of the above-described embodiment may be omitted by appropriately assigning the same reference numerals.
　図９に示すように、実施の形態４の空気調和装置４００の室外機４１０において、通信ユニット４５０におけるケース５１の内面の少なくとも一部には、電磁波を遮断または減衰させる電磁波シールド４５１ａが設けられている。実施の形態４において電磁波シールド４５１ａは、ケース５１のうち側壁部１１ｃに接触する幅方向他方側（－Ｙ側）の壁部の内面に設けられている。電磁波シールド４５１ａは、例えば、板金、金属網、または金属メッキなどで構成されている。 As shown in FIG. 9, in the outdoor unit 410 of the air conditioner 400 of Embodiment 4, at least part of the inner surface of the case 51 in the communication unit 450 is provided with an electromagnetic wave shield 451a that blocks or attenuates electromagnetic waves. there is In the fourth embodiment, the electromagnetic wave shield 451a is provided on the inner surface of the wall portion of the case 51 on the other side in the width direction (-Y side) that contacts the side wall portion 11c. The electromagnetic wave shield 451a is made of, for example, sheet metal, metal mesh, or metal plating.
　実施の形態４において差込部５７の内周面の少なくとも一部には、電磁波を遮断または減衰させる電磁波シールド４５７ａが設けられている。実施の形態４において電磁波シールド４５７ａは、差込部５７の内周面の全体に設けられている。電磁波シールド４５７ａは、電磁波シールド４５１ａと同様に、例えば、板金、金属網、または金属メッキなどで構成されている。 In Embodiment 4, at least part of the inner peripheral surface of the insertion portion 57 is provided with an electromagnetic wave shield 457a that blocks or attenuates electromagnetic waves. In the fourth embodiment, the electromagnetic wave shield 457a is provided on the entire inner peripheral surface of the insertion portion 57. As shown in FIG. The electromagnetic wave shield 457a is made of, for example, sheet metal, metal mesh, or metal plating, like the electromagnetic wave shield 451a.
　室外機４１０のその他の構成は、上述した各実施の形態における室外機のその他の構成と同様にできる。空気調和装置４００のその他の構成は、上述した各実施の形態における空気調和装置のその他の構成と同様にできる。 Other configurations of the outdoor unit 410 can be the same as other configurations of the outdoor units in each of the above-described embodiments. Other configurations of the air conditioner 400 can be the same as other configurations of the air conditioners in each of the above-described embodiments.
　実施の形態４によれば、通信ユニット４５０におけるケース５１の内面の少なくとも一部には、電磁波シールド４５１ａが設けられている。そのため、通信ユニット４５０のアンテナ部５５から放射される電磁波の一部を電磁波シールド４５１ａによって遮断または減衰させることができる。これにより、通信ユニット４５０を筐体１１に取り付けることで通信ユニット４５０が筐体１１内の制御部１７に近い位置に配置されても、アンテナ部５５から放射される電磁波が制御部１７の電気部品に影響を与えることを抑制できる。したがって、制御部１７が誤動作することを抑制できる。 According to Embodiment 4, at least part of the inner surface of the case 51 of the communication unit 450 is provided with an electromagnetic shield 451a. Therefore, part of the electromagnetic waves radiated from the antenna section 55 of the communication unit 450 can be blocked or attenuated by the electromagnetic wave shield 451a. As a result, even if the communication unit 450 is arranged in the housing 11 at a position close to the control unit 17 by attaching the communication unit 450 to the housing 11 , the electromagnetic waves emitted from the antenna unit 55 will not affect the electric components of the control unit 17 . can be suppressed from affecting Therefore, it is possible to prevent the control unit 17 from malfunctioning.
　また、実施の形態４によれば、差込部５７の内周面の少なくとも一部には、電磁波シールド４５７ａが設けられている。そのため、通信ユニット４５０のアンテナ部５５から放射される電磁波の一部を電磁波シールド４５７ａによって遮断または減衰させることができる。これにより、アンテナ部５５から放射される電磁波が制御部１７と通信ユニット４５０とを繋ぐ電気通信路を流れる信号に影響を与えることを抑制できる。したがって、制御部１７と通信ユニット４５０との間に流れる信号にエラーが生じることを抑制できる。 Further, according to Embodiment 4, at least part of the inner peripheral surface of the insertion portion 57 is provided with an electromagnetic wave shield 457a. Therefore, part of the electromagnetic waves radiated from the antenna section 55 of the communication unit 450 can be blocked or attenuated by the electromagnetic wave shield 457a. Accordingly, it is possible to suppress the influence of the electromagnetic wave emitted from the antenna section 55 on the signal flowing through the electrical communication path connecting the control section 17 and the communication unit 450 . Therefore, it is possible to suppress the occurrence of errors in signals flowing between the control section 17 and the communication unit 450 .
　なお、電磁波シールド４５１ａは、通信ユニット４５０におけるケース５１の内面の全体に設けられていてもよい。電磁波シールド４５７ａは、差込部５７の内周面の一部のみに設けられていてもよい。 The electromagnetic wave shield 451a may be provided on the entire inner surface of the case 51 of the communication unit 450.

　実施の形態５．
　図１０は、実施の形態５における室外機５１０の一部を示す斜視図である。なお、以下の説明において、上述した実施の形態と同様の構成については、適宜同一の符号を付す等により説明を省略する場合がある。 Embodiment 5.
FIG. 10 is a perspective view showing part of the outdoor unit 510 according to the fifth embodiment. It should be noted that, in the following description, the same configurations as those of the above-described embodiment may be omitted by appropriately assigning the same reference numerals.
　図１０に示すように、実施の形態５の空気調和装置５００の室外機５１０は、筐体５１１のうち幅方向一方側（＋Ｙ側）の側壁部５１１ｃに設けられた開口部５１８を開閉可能な開閉機構５７０を備える。実施の形態５において開口部５１８は、実施の形態１と異なりノックアウト穴ではなく、予め筐体５１１に形成された穴である。図１０では、開閉機構５７０によって開口部５１８が閉じられた状態を示している。 As shown in FIG. 10, the outdoor unit 510 of the air conditioner 500 of Embodiment 5 can open and close the opening 518 provided in the side wall portion 511c on one width direction side (+Y side) of the housing 511. An opening/closing mechanism 570 is provided. In Embodiment 5, opening 518 is not a knockout hole as in Embodiment 1, but a hole formed in housing 511 in advance. FIG. 10 shows the opening 518 closed by the opening/closing mechanism 570 .
　開閉機構５７０は、側壁部５１１ｃの外側面に固定されている。開閉機構５７０は、スライド部５７１と、一対のレール部５７２と、ストッパ部５７３と、を有する。一対のレール部５７２は、前後方向に延びている。一対のレール部５７２は、鉛直方向に間隔を空けて配置されている。一対のレール部５７２は、開口部５１８を鉛直方向に挟んで配置されている。ストッパ部５７３は、鉛直方向に延び、一対のレール部５７２の後側（－Ｘ側）の端部同士を繋いでいる。 The opening/closing mechanism 570 is fixed to the outer surface of the side wall portion 511c. The opening/closing mechanism 570 has a slide portion 571 , a pair of rail portions 572 and a stopper portion 573 . The pair of rail portions 572 extends in the front-rear direction. The pair of rail portions 572 are arranged with an interval in the vertical direction. The pair of rail portions 572 are arranged to sandwich the opening 518 in the vertical direction. The stopper portion 573 extends in the vertical direction and connects the rear (−X side) ends of the pair of rail portions 572 .
　スライド部５７１は、一対のレール部５７２同士の鉛直方向の間に位置する。スライド部５７１は、一対のレール部５７２によって前後方向に移動可能に支持されている。実施の形態５においてスライド部５７１は、略正方形板状である。スライド部５７１は、ストッパ部５７３に前方（＋Ｘ方）から接触する位置において開口部５１８を幅方向一方側（＋Ｙ側）から覆って塞いでいる。図１０において矢印で示すように、スライド部５７１を前方にスライド移動させることで、開口部５１８を開くことができる。これにより、開口部５１８に筐体５１１の外部から通信ユニット５０を取り付け可能にできる。 The slide portion 571 is positioned between the pair of rail portions 572 in the vertical direction. The slide portion 571 is supported by a pair of rail portions 572 so as to be movable in the front-rear direction. In Embodiment 5, the slide portion 571 has a substantially square plate shape. The slide portion 571 covers and blocks the opening portion 518 from one side (+Y side) in the width direction at a position where it contacts the stopper portion 573 from the front (+X direction). As indicated by the arrow in FIG. 10, the opening 518 can be opened by sliding the sliding portion 571 forward. Thereby, the communication unit 50 can be attached to the opening 518 from the outside of the housing 511 .
　室外機５１０のその他の構成は、上述した各実施の形態における室外機のその他の構成と同様にできる。空気調和装置５００のその他の構成は、上述した各実施の形態における空気調和装置のその他の構成と同様にできる。 Other configurations of the outdoor unit 510 can be the same as other configurations of the outdoor units in each of the above-described embodiments. Other configurations of the air conditioner 500 can be the same as other configurations of the air conditioners in the above-described embodiments.
　実施の形態５によれば、室外機５１０は、開口部５１８を開閉可能な開閉機構５７０を備える。そのため、開口部５１８をノックアウト穴とせずに筐体５１１に予め開口部５１８が形成されていても、通信ユニット５０を取り付ける前において、開閉機構５７０によって、開口部５１８を閉じておくことができる。そのため、開口部５１８をノックアウト穴にしなくても、開口部５１８から雨や埃などの異物が筐体５１１内に侵入することを抑制できる。また、ノックアウト穴と異なり、通信ユニット５０を取り付ける際に、筐体５１１の一部を取り除く必要がないため、実施の形態１のノックアウト部１１ｄのような破片が生じない。また、例えば、一度取り付けた通信ユニット５０を筐体５１１から取り外した場合などに、開閉機構５７０によって開口部５１８を再び閉じることができる。そのため、一度取り付けた通信ユニット５０を筐体５１１から取り外す場合であっても、開口部５１８から雨や埃などの異物が筐体５１１内に侵入することを抑制できる。 According to Embodiment 5, the outdoor unit 510 includes an opening/closing mechanism 570 capable of opening/closing the opening 518 . Therefore, even if the opening 518 is not used as a knockout hole and is formed in the housing 511 in advance, the opening 518 can be closed by the opening/closing mechanism 570 before the communication unit 50 is attached. Therefore, foreign matter such as rain or dust can be prevented from entering the housing 511 through the opening 518 without using the opening 518 as a knockout hole. Moreover, unlike the knockout hole, when the communication unit 50 is attached, there is no need to remove a part of the housing 511. Therefore, a fragment unlike the knockout portion 11d of the first embodiment does not occur. In addition, for example, when the communication unit 50 once attached is removed from the housing 511 , the opening 518 can be closed again by the opening/closing mechanism 570 . Therefore, even when the communication unit 50 once attached is removed from the housing 511 , it is possible to prevent foreign matter such as rain or dust from entering the housing 511 through the opening 518 .
　実施の形態６．
　図１１は、実施の形態６における室外機６１０の一部を前方から見た図である。なお、以下の説明において、上述した実施の形態と同様の構成については、適宜同一の符号を付す等により説明を省略する場合がある。 Embodiment 6.
FIG. 11 is a front view of part of the outdoor unit 610 according to the sixth embodiment. It should be noted that, in the following description, the same configurations as those of the above-described embodiment may be omitted by appropriately assigning the same reference numerals.
　図１１に示すように、実施の形態６の空気調和装置６００の室外機６１０において、開口部６１８は、運搬ハンドル部１９が取り付けられる取付穴である。つまり、実施の形態６において開口部６１８には、運搬ハンドル部１９を取り付け可能である。通信ユニット６５０を取り付ける作業者は、運搬ハンドル部１９を開口部６１８から取り外して、開口部６１８に通信ユニット６５０を差し込む。実施の形態６において通信ユニット６５０は、例えば、上述した実施の形態１における本体部５６と同様の形状である。実施の形態６において通信ユニット６５０は、全体が開口部６１８から筐体６１１内に差し込まれる差込部である。 As shown in FIG. 11, in the outdoor unit 610 of the air conditioner 600 of Embodiment 6, the opening 618 is a mounting hole to which the carrying handle 19 is mounted. In other words, the carrying handle 19 can be attached to the opening 618 in the sixth embodiment. A worker who installs the communication unit 650 removes the carrying handle 19 from the opening 618 and inserts the communication unit 650 into the opening 618 . The communication unit 650 in the sixth embodiment has, for example, the same shape as the body section 56 in the first embodiment described above. In Embodiment 6, communication unit 650 is a plug-in portion that is entirely inserted into housing 611 through opening 618 .
　室外機６１０のその他の構成は、上述した各実施の形態における室外機のその他の構成と同様にできる。空気調和装置６００のその他の構成は、上述した各実施の形態における空気調和装置のその他の構成と同様にできる。 Other configurations of the outdoor unit 610 can be the same as other configurations of the outdoor units in each of the above-described embodiments. Other configurations of the air conditioner 600 can be the same as other configurations of the air conditioners in each of the above-described embodiments.
　実施の形態６によれば、開口部６１８には、運搬ハンドル部１９を取り付け可能である。そのため、運搬ハンドル部１９が取り付けられる穴を、通信ユニット６５０の差込部を差し込む開口部６１８として利用できる。これにより、通信ユニット６５０を取り付けるための開口部を別途作る必要がなく、筐体６１１に設けられる穴の数を少なくできる。また、通信ユニット６５０を取り付ける前には、開口部６１８を運搬ハンドル部１９で塞いでおくことができる。そのため、通信ユニット６５０を取り付ける前において、開口部６１８から雨や埃などの異物が筐体６１１内に侵入することを抑制できる。 According to Embodiment 6, the carrying handle 19 can be attached to the opening 618 . Therefore, the hole in which the carrying handle portion 19 is attached can be used as the opening portion 618 into which the insertion portion of the communication unit 650 is inserted. As a result, there is no need to separately form an opening for attaching the communication unit 650, and the number of holes provided in the housing 611 can be reduced. Also, the opening 618 can be closed with the carrying handle 19 before the communication unit 650 is attached. Therefore, it is possible to prevent foreign matter such as rain or dust from entering the housing 611 through the opening 618 before the communication unit 650 is attached.
　また、実施の形態６によれば、通信ユニット６５０は、全体が開口部６１８に差し込まれる差込部である。そのため、通信ユニット６５０が筐体６１１の外部に突出することを抑制できる。これにより、通信ユニット６５０が邪魔になることを抑制できる。 Also, according to Embodiment 6, the communication unit 650 is an insertion part that is entirely inserted into the opening 618 . Therefore, it is possible to prevent the communication unit 650 from protruding outside the housing 611 . This can prevent the communication unit 650 from becoming an obstacle.
　なお、通信ユニット６５０を上述した実施の形態１から実施の形態５と同様に本体部と差込部とを有する構成とし、運搬ハンドル部１９が取り付けられていた開口部６１８に差込部を差し込んで、通信ユニット６５０を筐体６１１に取り付ける構成としてもよい。 In addition, the communication unit 650 is configured to have a main body portion and an insertion portion in the same manner as in the above-described Embodiments 1 to 5, and the insertion portion is inserted into the opening 618 to which the carrying handle portion 19 was attached. Alternatively, the communication unit 650 may be attached to the housing 611 .
　以上に本開示における実施の形態について説明したが、本開示は上述した各実施の形態の構成のみに限定されず、以下の構成および方法を採用することもできる。 Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the configurations of the embodiments described above, and the following configurations and methods can also be adopted.
　通信ユニットは、接続端子が室外機の筐体内で制御部と接続されるならば、どのように室外機の筐体に取り付けられてもよい。通信ユニットは、開口部に差し込まれる差込部以外の部分が筐体に固定されて取り付けられてもよい。 The communication unit may be attached to the housing of the outdoor unit in any way as long as the connection terminal is connected to the control unit within the housing of the outdoor unit. The communication unit may be attached by fixing the portion other than the insertion portion that is inserted into the opening to the housing.
　運搬ハンドル部に設けられた作業者の手指が掛けられる溝部を室外機の筐体内まで貫通させて、当該溝部を通信ユニットの差込部が差し込まれる開口部として利用してもよい。この構成では、運搬ハンドル部を取り外すことなく、運搬ハンドル部の溝部を介して通信ユニットを筐体に取り付けることができる。 The groove provided in the carrying handle, where the operator's fingers can be hung, may be penetrated into the housing of the outdoor unit, and the groove may be used as an opening into which the insertion part of the communication unit is inserted.
