　この発明は空気調和機に関する。 This invention relates to an air conditioner.
　従来、空気調和機としては、特開２０００－３５２６７号公報(特許文献１)に開示されているように、リモートコントローラに搭載したセンサを用いて、室内機からの冷媒漏れを検出するものがある。この冷媒漏れが検出されると、室内機は、運転中であれば、運転が停止する一方、停止中であれば、運転ができなくなる。 Conventionally, as an air conditioner, there is one that detects refrigerant leakage from an indoor unit using a sensor mounted on a remote controller, as disclosed in JP 2000-35267 A (Patent Document 1). . When this refrigerant leak is detected, the indoor unit stops operating if it is in operation, but cannot operate if it is stopped.
　また、上記室内機はＬＥＤ(発光ダイオード)を有し、このＬＥＤが冷媒漏れの検出に応じて点滅する。これにより、ユーザへの冷媒漏れの報知が図られている。 Also, the indoor unit has an LED (light emitting diode), and this LED blinks in response to detection of refrigerant leakage. Thereby, the notification of the refrigerant leak to the user is achieved.
特開２０００－３５２６７号公報JP 2000-35267 A
　しかしながら、上記従来の空気調和機では、ユーザが室内機から離れた場所にいると、ＬＥＤを視認できないため、冷媒漏れに気付かないという問題がある。 However, the above-described conventional air conditioner has a problem that when the user is away from the indoor unit, the LED cannot be visually recognized, so that the refrigerant leakage is not noticed.
　そこで、この発明の課題は、ユーザが冷媒漏れに気付く可能性を高めて、冷媒漏れによるリスクを低減できる空気調和機を提供することにある。 Therefore, an object of the present invention is to provide an air conditioner that increases the possibility that a user will notice a refrigerant leak and can reduce the risk due to the refrigerant leak.
　冷媒は、漏洩後、自然換気などの効果によって自然に拡散していくが、急速漏洩すると、拡散が追いつかなくなって、冷媒濃度が高い箇所が一時的に生じ、着火および窒息のリスクが高まる恐れがある。 After leakage, the refrigerant naturally diffuses due to natural ventilation and other effects. However, if it leaks rapidly, the diffusion cannot catch up, and a location with a high refrigerant concentration may temporarily occur, increasing the risk of ignition and suffocation. is there.
　この発明の空気調和機は、冷媒の急速漏洩が生じた場合に、冷媒の漏れ情報が外部の端末に送信されるので、ユーザに換気を促して、上記箇所の冷媒濃度を下げることができる。 In the air conditioner of the present invention, when the refrigerant leaks rapidly, the refrigerant leak information is transmitted to the external terminal, so that the user can be ventilated and the refrigerant concentration at the above location can be lowered.

And a communication device control unit.
　上記構成によれば、上記冷媒漏れ判定部によって、冷媒の漏れが発生したと判定された場合、通信装置制御部は、冷媒の漏れ情報が通信装置から無線を介して外部の端末へ送信されるように、通信装置を制御する。これにより、ユーザは、空気調和機から離れた場所にいても、上記端末の近くにいれば、冷媒の漏れ情報を知ることができる。したがって、ユーザが冷媒漏れに気付く可能性を高めて、冷媒漏れによるリスクを低減できる。 According to the above configuration, when the refrigerant leakage determination unit determines that a refrigerant leak has occurred, the communication device control unit transmits the refrigerant leakage information from the communication device to an external terminal via radio. In this way, the communication device is controlled. Thereby, even if the user is in a place away from the air conditioner, the user can know the leakage information of the refrigerant if the user is near the terminal. Therefore, it is possible to increase the possibility that the user will notice the refrigerant leakage and reduce the risk due to the refrigerant leakage.
　また、上記冷媒の漏れ情報が通信装置から無線を介して外部の端末へ送信されるので、ユーザと空気調和機の間に例えば壁があっても、上記端末は冷媒の漏れ情報を受信できる。 Also, since the refrigerant leakage information is transmitted from the communication device to an external terminal via radio, the terminal can receive the refrigerant leakage information even if there is a wall between the user and the air conditioner.
　一実施形態の空気調和機は、
　上記端末を複数記憶可能な端末記憶部を備え、
　上記端末が上記端末記憶部に複数記憶されている場合、上記通信装置制御部は、上記端末記憶部に記憶されている上記複数の端末の全てに上記冷媒の漏れ情報が送信されるように、上記通信装置を制御する。 The air conditioner of one embodiment is
A terminal storage unit capable of storing a plurality of the terminals,
When a plurality of the terminals are stored in the terminal storage unit, the communication device control unit transmits the refrigerant leakage information to all of the plurality of terminals stored in the terminal storage unit. Control the communication device.
　上記実施形態によれば、上記端末が上記端末記憶部に複数記憶されている場合、通信装置制御部は、端末記憶部に記憶されている複数の端末の全てに冷媒の漏れ情報が送信されるように、通信装置を制御する。これにより、ユーザが冷媒漏れに気付く可能性をより高めることができる。 According to the embodiment, when a plurality of the terminals are stored in the terminal storage unit, the communication device control unit transmits refrigerant leakage information to all of the plurality of terminals stored in the terminal storage unit. In this way, the communication device is controlled. Thereby, possibility that a user will notice refrigerant | coolant leakage can be raised more.
　一実施形態の空気調和機では、
　上記冷媒の漏れ情報はプッシュ通知で送信される。 In the air conditioner of one embodiment,

　この発明の空気調和機は、冷媒漏れ判定部によって、冷媒の漏れが発生したと判定された場合、通信装置制御部は、冷媒の漏れ情報が通信装置から無線を介して外部の端末へ送信されるように、通信装置を制御するので、ユーザが冷媒漏れに気付く可能性を高めて、冷媒漏れによるリスクを低減できる。 In the air conditioner of the present invention, when the refrigerant leakage determination unit determines that a refrigerant leak has occurred, the communication device control unit transmits the refrigerant leakage information from the communication device to an external terminal via radio. Thus, since the communication device is controlled, the possibility that the user notices the refrigerant leakage can be increased, and the risk due to the refrigerant leakage can be reduced.
　また、上記冷媒の漏れ情報が通信装置から無線を介して外部の端末へ送信されるので、ユーザと空気調和機の間に例えば壁があっても、外部の端末は冷媒の漏れ情報を受信できる。 In addition, since the refrigerant leakage information is transmitted from the communication device to an external terminal via radio, the external terminal can receive the refrigerant leakage information even if there is a wall between the user and the air conditioner. .

The smartphone 201 also includes the same components as the display unit 111, the control device 112, the communication device 113, and the operation unit 114.
　上記表示部１１１は、通信装置１１３から可燃性冷媒の漏れ情報を受信すると、着火および窒息のリスクを下げるため、例えば「冷媒漏れが発生！火を消し、換気して下さい！」をポップアップ表示する。このような表示部１１１としては、例えばタッチパネル式液晶表示部が採用される。この場合、上記液晶表示部は操作部としての役割も果たす。 When the display unit 111 receives the flammable refrigerant leakage information from the communication device 113, the display unit 111 pops up, for example, “Refrigerant leakage has occurred! Turn off the fire and ventilate!” In order to reduce the risk of ignition and suffocation. . As such a display unit 111, for example, a touch panel type liquid crystal display unit is employed. In this case, the liquid crystal display unit also serves as an operation unit.
　上記制御装置１１２は、通信装置１１３や操作部１１４などからの信号に基づいて、表示部１１１の表示を変更する。 The control device 112 changes the display on the display unit 111 based on signals from the communication device 113, the operation unit 114, and the like.

In addition, when control of the said flowchart is performed, the terminal memory | storage part 6 shall memorize | store the some smart phone 101,201. The control in the flowchart is performed both when the air conditioner is operating and when the operation is stopped.
　上記制御がスタートすると、ステップＳ１で、可燃性冷媒の漏れが発生した否かを、冷媒漏れ判定部５ａが判定する。このステップＳ１は、上記可燃性冷媒の漏れが発生したと判定するまで繰り返される。 When the above control is started, the refrigerant leakage determination unit 5a determines whether or not the leakage of the combustible refrigerant has occurred in step S1. This step S1 is repeated until it is determined that leakage of the combustible refrigerant has occurred.
　次に、ステップＳ２で、可燃性冷媒の漏れ情報が無線ＬＡＮアダプタ４から無線を介してスマートフォン１０１，２０１の全てにプッシュ通知で送信されるように、無線ＬＡＮアダプタ制御部５ｂが無線ＬＡＮアダプタ４を制御して、スマートフォン１０１，２０１を保有するユーザに可燃性冷媒の漏れを知らせる。 Next, in step S2, the wireless LAN adapter control unit 5b transmits the wireless LAN adapter controller 5b to the smartphones 101 and 201 via a wireless communication from the wireless LAN adapter 4 via wireless communication. To notify the user who owns the smartphone 101, 201 of the leakage of the flammable refrigerant.
　最後に、上記警報器を作動させて、室内機１の近くにいる人に可燃性冷媒の漏れをユーザに知らせる。 Finally, the alarm is activated to notify the user near the indoor unit 1 that the flammable refrigerant has leaked.

Therefore, it is possible to increase the possibility that the user will notice the refrigerant leakage and reduce the risk due to the refrigerant leakage.
　また、上記可燃性冷媒の漏れ情報が無線ＬＡＮアダプタ４から無線を介してスマートフォン１０１，２０１に送信されるので、ユーザと空気調和機の間に例えば壁があっても、スマートフォン１０１，２０１は冷媒の漏れ情報を受信できる。 Moreover, since the leakage information of the combustible refrigerant is transmitted from the wireless LAN adapter 4 to the smartphones 101 and 201 via radio, the smartphones 101 and 201 are refrigerant even if there is a wall between the user and the air conditioner. Leak information can be received.
　また、上記可燃性冷媒の漏れ情報はスマートフォン１０１，２０１の両方に送信されるので、ユーザが冷媒漏れに気付く可能性をより高めることができる。 Moreover, since the leakage information of the combustible refrigerant is transmitted to both the smartphones 101 and 201, the possibility that the user will notice the refrigerant leakage can be further increased.
　また、上記可燃性冷媒の漏れ情報はプッシュ通知で送信されるので、ユーザの手間を増やさずに、ユーザが冷媒漏れに気付く可能性をより高めることができる。 In addition, since the flammable refrigerant leakage information is transmitted by push notification, it is possible to further increase the possibility that the user will notice the refrigerant leakage without increasing the user's trouble.
