　冷房運転および除湿運転では、図示実線矢印で示すように、圧縮機１０から吐出された冷媒が四方弁１１から室外熱交換器１２、膨張弁１３、室内熱交換器１４へと順に流れ、室内熱交換器１４を経た冷媒が四方弁１１を通って圧縮機１０に戻る冷房サイクルまたは除湿サイクルが形成される。すなわち、室外熱交換器１２が凝縮器、室内熱交換器１４が蒸発器として機能する。 In the cooling operation and the dehumidifying operation, the refrigerant discharged from the compressor 10 sequentially flows from the four-way valve 11 to the outdoor heat exchanger 12, the expansion valve 13, and the indoor heat exchanger 14 as indicated by the solid line arrows in the figure. A cooling cycle or a dehumidification cycle is formed in which the refrigerant having passed through the exchanger 14 returns to the compressor 10 through the four-way valve 11. That is, the outdoor heat exchanger 12 functions as a condenser and the indoor heat exchanger 14 functions as an evaporator.
　一方、暖房運転では、四方弁１１が切換わることにより、図示破線矢印で示すように、圧縮機１０から吐出される冷媒が四方弁１１から室内熱交換器１４、膨張弁１３、室外熱交換器１２へと順に流れ、室外熱交換器１２を経た冷媒が四方弁１１を通って圧縮機１０に戻る暖房サイクルが形成される。すなわち、室内熱交換器１４が凝縮器、室外熱交換器１２が蒸発器として機能する。 On the other hand, in the heating operation, when the four-way valve 11 is switched, the refrigerant discharged from the compressor 10 is transferred from the four-way valve 11 to the indoor heat exchanger 14, the expansion valve 13, and the outdoor heat exchanger as indicated by broken arrows in the figure. A heating cycle is formed in which the refrigerant flows in sequence to 12 and the refrigerant that has passed through the outdoor heat exchanger 12 returns to the compressor 10 through the four-way valve 11. That is, the indoor heat exchanger 14 functions as a condenser, and the outdoor heat exchanger 12 functions as an evaporator.
　室内機２内には、室内熱交換器１４に対向した室内ファン１６が配置される。室内機２の吹出口には、上下方向について吹き出し方向を変更する上下フラップ１７が配置される。そして、図１に示すように、室内機２に、室内温度を検出する室内温度センサ（室内温度検出手段）２１と、室内湿度を検出する室内湿度センサ（室内湿度検出手段）２２が取付けられる。また、室内機２は、室内（空調空間）にいる人を検知する人検知センサ（人検知手段）２５を有している。 In the indoor unit 2, an indoor fan 16 facing the indoor heat exchanger 14 is disposed. At the outlet of the indoor unit 2, an upper and lower flap 17 that changes the blowing direction in the vertical direction is arranged. As shown in FIG. 1, an indoor temperature sensor (indoor temperature detecting means) 21 for detecting the indoor temperature and an indoor humidity sensor (indoor humidity detecting means) 22 for detecting the indoor humidity are attached to the indoor unit 2. Moreover, the indoor unit 2 has a human detection sensor (human detection means) 25 that detects a person in the room (air-conditioned space).
　空気調和機１の制御部５０には、空気調和機１に係る各種動作の制御プログラムやデータなどが格納されたＲＯＭ、空気調和機１の各部の動作を制御する信号を生成するために各種演算を実行するＣＰＵ、各種設定やＣＰＵでの演算結果などのデータを一時保管するＲＡＭなどの部材が含まれている。これら各種部材およびソフトウェアによって、図２に示すように、タイマー５１と、不在判断部５２とが形成されている。 The control unit 50 of the air conditioner 1 includes a ROM in which control programs and data for various operations related to the air conditioner 1 are stored, and various calculations for generating signals for controlling the operations of the respective units of the air conditioner 1. And a member for temporarily storing data such as various settings and calculation results in the CPU. These various members and software form a timer 51 and an absence determination unit 52 as shown in FIG.
タイマー５１は、人検知センサ２５によって空調空間にいる人が検知されない状態において、空気調和機１の運転の継続時間を計測する。 The timer 51 measures the duration of the operation of the air conditioner 1 in a state where no person in the air-conditioned space is detected by the human detection sensor 25.
不在判断部５２は、人検知センサ２５によって空調空間にいる人が検知されない状態で、かつ、空気調和機１の運転が所定の不在時間（所定時間）継続された場合に、空調空間に人がいないと判断する。したがって、不在判断部５２は、タイマー５１での計測時間が所定の不在時間に到達した場合に、不在情報を端末装置３０に供給すると判断する The absence determination unit 52 is in a state where a person in the air-conditioned space is not detected by the human detection sensor 25 and when the operation of the air conditioner 1 is continued for a predetermined absence time (predetermined time), Judge that there is not. Therefore, the absence determination unit 52 determines that the absence information is supplied to the terminal device 30 when the time measured by the timer 51 reaches a predetermined absence time.
また、空気調和機１の制御部５０には、圧縮機１０と、四方弁１１、膨張弁１３と、室内ファン１６を駆動するモータ１６ａと、上下フラップ１７を駆動するモータ１７ａと、室内温度センサ２１と、室内湿度センサ２２と、人検知センサ２５と、空気調和機１に付属されたコントローラ２８とが接続される。また、空気調和機１の制御部５０は、ユーザの端末装置３０から供給された運転変更命令に基づいて空気調和機１の運転を変更する。ユーザの端末装置３０は、例えばスマートフォンなどの液晶端末であって、ネットワークを介して、空気調和機１に対して運転変更命令（運転開始操作、運転停止操作、室内温度の設定温度等）を供給することができる。したがって、制御部５０は、コントローラ２８やユーザの端末装置３０からの指令（運転開始操作、運転停止操作、室内温度の設定温度等）や、室内温度センサ２１で検知される室内温度や、室内湿度センサ２２で検知される室内湿度に基づいて、空気調和機１の運転を制御する。このように、本実施形態の空気調和機１は、コントローラ２８からの指令（運転開始操作、運転停止操作、室内温度の設定温度等）に基づいて運転状態が変更されるだけでなく、ユーザの端末装置３０から供給される運転変更命令（運転開始操作、運転停止操作、室内温度の設定温度等）に基づいて運転状態が変更されるものである。 The controller 50 of the air conditioner 1 includes a compressor 10, a four-way valve 11, an expansion valve 13, a motor 16a that drives the indoor fan 16, a motor 17a that drives the upper and lower flaps 17, and an indoor temperature sensor. 21, indoor humidity sensor 22, human detection sensor 25, and controller 28 attached to air conditioner 1 are connected. The control unit 50 of the air conditioner 1 changes the operation of the air conditioner 1 based on the operation change command supplied from the user terminal device 30. The user terminal device 30 is a liquid crystal terminal such as a smartphone, for example, and supplies an operation change command (operation start operation, operation stop operation, set temperature of the room temperature, etc.) to the air conditioner 1 via the network. can do. Therefore, the control unit 50 controls the commands from the controller 28 and the user terminal device 30 (operation start operation, operation stop operation, set temperature of the room temperature, etc.), the room temperature detected by the room temperature sensor 21, and the room humidity. Based on the indoor humidity detected by the sensor 22, the operation of the air conditioner 1 is controlled. As described above, the air conditioner 1 of the present embodiment not only changes the operation state based on the commands from the controller 28 (operation start operation, operation stop operation, indoor temperature set temperature, etc.), The operation state is changed based on an operation change command (operation start operation, operation stop operation, indoor temperature set temperature, etc.) supplied from the terminal device 30.
　ここで、コントローラ２８には、表示部と、温度調整部と、運転開始ボタンと、停止ボタンとが設けられている。また、コントローラ２８には、運転選択部と、風量選択部と、風向選択部とが設けられている。 Here, the controller 28 is provided with a display unit, a temperature adjustment unit, an operation start button, and a stop button. Further, the controller 28 is provided with an operation selection unit, an air volume selection unit, and an air direction selection unit.
　表示部には、運転表示部と、設定温度表示部と、運転モード表示部とが表示されている。運転表示部には、運転選択部で選択された運転（自動、冷房、暖房、除湿及び送風のいずれかの運転）が表示される。また、設定温度表示部には、温度調整部を操作することで変更された温度が表示される。 In the display section, an operation display section, a set temperature display section, and an operation mode display section are displayed. The operation selected by the operation selection unit (automatic, cooling, heating, dehumidification, and blowing operation) is displayed on the operation display unit. Moreover, the temperature changed by operating the temperature adjustment part is displayed on the set temperature display part.
　温度調整部は設定温度を変更するものであり、温度調整部を操作して設定温度を上げたり、温度調整部を操作して設定温度を下げることができる。運転開始ボタンを押すことにより運転選択部により選択した運転が開始され、運転中に停止ボタンを押すことにより運転が停止される。 The temperature adjustment unit changes the set temperature. The temperature adjustment unit can be operated to increase the set temperature, or the temperature adjustment unit can be operated to decrease the set temperature. The operation selected by the operation selection unit is started by pressing the operation start button, and the operation is stopped by pressing the stop button during the operation.
　コントローラ２８の運転選択部により、自動、冷房、暖房、除湿及び送風のいずれかに切り換えて選択できる。風量選択部により、風量を自動、微（微量）、弱（少量）及び強（多量）のいずれかに切り換えて選択できる。風向選択部により、風向を自動、上（上方向）、中（水平方向）及び下（下方向）のいずれかに切り換えて選択できる。 The operation selection unit of the controller 28 can be switched between automatic, cooling, heating, dehumidification and ventilation. The air volume selection unit can select the air volume by switching between automatic, fine (small amount), weak (small amount), and strong (large amount). The wind direction can be selected from the automatic, upward (upward), middle (horizontal), and downward (downward) directions by the wind direction selector.
そして、コントローラ２８には、モード切換部が設けられている。モード切換部により、空気調和機１の高温防止モードを、強制運転モード、お知らせモード及び切のいずれかに切り換えることができる。本実施形態の空気調和機１では、高温防止モードが切に切り換えられた場合、不在お知らせモードが設定される。 The controller 28 is provided with a mode switching unit. By the mode switching unit, the high temperature prevention mode of the air conditioner 1 can be switched to any one of the forced operation mode, the notification mode, and the off mode. In the air conditioner 1 of the present embodiment, the absence notification mode is set when the high temperature prevention mode is switched off.
したがって、本実施形態の空気調和機１では、モード切換部によって、強制運転モード、お知らせモード及び不在お知らせモード（高温防止モードの切）のいずれかが設定される。よって、空気調和機１において、強制運転モードでの運転と、お知らせモードでの運転と、不在お知らせモードでの運転とは同時に行われることはない。 Therefore, in the air conditioner 1 of the present embodiment, any one of the forced operation mode, the notification mode, and the absence notification mode (high temperature prevention mode off) is set by the mode switching unit. Therefore, in the air conditioner 1, the operation in the forced operation mode, the operation in the notification mode, and the operation in the absence notification mode are not performed simultaneously.
　強制運転モードでは、室内が高温状態や高湿状態である場合に、室内温度及び室内湿度に基づいて、強制運転が自動的に開始される。したがって、強制運転モードに切り換えた場合、室内が高温状態や高湿状態になったときに、ユーザがコントローラ２８や端末装置３０によって運転開始操作を行わなかった場合でも、強制運転が自動的に開始されて、室内温度及び室内湿度が低下する。 In the forced operation mode, when the room is in a high temperature state or a high humidity state, the forced operation is automatically started based on the room temperature and the room humidity. Therefore, when the operation mode is switched to the forced operation mode, the forced operation is automatically started even when the user does not perform the operation start operation by the controller 28 or the terminal device 30 when the room is in a high temperature state or a high humidity state. As a result, the room temperature and the room humidity decrease.
　お知らせモードでは、室内が高温状態や高湿状態である場合に、室内温度及び室内湿度に基づいて、運転開始を促す報知が自動的に行われる。運転開始を促す報知としては、例えば、「室内が高温になっています。冷房運転を開始してください。」という内容が、室内機２から音声で報知されたり、室内機２の表示部に表示される。 In the notification mode, when the room is in a high temperature state or a high humidity state, a notification that prompts the start of operation is automatically performed based on the room temperature and the room humidity. As a notification to prompt the start of operation, for example, the content “The room is hot. Please start cooling operation” is notified by voice from the indoor unit 2 or displayed on the display unit of the indoor unit 2 Is done.
不在お知らせモードでは、人検知センサ２５によって室内にいる人が検知されない状態で、かつ、空気調和機１の運転が所定の不在時間だけ継続された場合に、室内に人がいないことを示す不在情報をユーザの端末装置３０に供給する。本実施形態の空気調和機１では、不在お知らせモードにおいて不在情報がユーザの端末装置３０に供給された場合、不在情報として、例えば、「室内に人がいない状態で空気調和機が運転されています。」という内容が、ユーザの端末装置３０に供給され、端末装置３０の表示画面に表示される。このとき、空気調和機１から供給された不在情報は、ユーザの端末装置３０に記憶されるので、空気調和機１から不在情報が一度供給された後において、ユーザは、端末装置３０に記憶された不在情報を見ることができる。したがって、本発明の空気調和機１では、不在情報を端末装置３０に一度供給すると、その後、ユーザは端末装置３０に記憶された不在情報を見ることができるので、不在情報を何度も繰り返して端末装置３０に供給しない。 In the absence notification mode, when there is no person in the room detected by the human detection sensor 25 and the operation of the air conditioner 1 is continued for a predetermined absence time, absence information indicating that there is no person in the room Is supplied to the terminal device 30 of the user. In the air conditioner 1 of this embodiment, when absence information is supplied to the user's terminal device 30 in the absence notification mode, for example, as the absence information, “the air conditioner is operated in a state where there is no person in the room "Is supplied to the terminal device 30 of the user and displayed on the display screen of the terminal device 30. At this time, since the absence information supplied from the air conditioner 1 is stored in the user's terminal device 30, after the absence information is once supplied from the air conditioner 1, the user is stored in the terminal device 30. You can see the absence information. Therefore, in the air conditioner 1 of the present invention, once the absence information is supplied to the terminal device 30, the user can view the absence information stored in the terminal device 30 thereafter. It is not supplied to the terminal device 30.
また、本実施形態の空気調和機１では、不在お知らせモードにおいて、人検知センサ２５によって室内にいる人が検知される状態で端末装置３０から運転停止命令が供給された場合に、この運転停止命令に対して、確認通知が端末装置３０に供給される。運転停止命令に対して確認通知として、例えば、室内に人がいることを示す情報を含む内容であって、「室内に人がいますが、空気調和機の運転を停止しますか。」という内容が、ユーザの端末装置３０に供給され、端末装置３０の表示画面に表示される。このとき、表示画面には、この確認通知とともに、運転停止命令に基づく運転停止を実行するか否かをユーザに選択させる選択部（図示しない）が表示される。したがって、ユーザは、端末装置３０に対して、運転停止を実行する操作か、または、運転停止を実行しない操作を行う。このように、本実施形態では、ユーザが、室内にいる人が検知される状態で端末装置３０から運転停止命令を空気調和機１に供給した場合に、その運転停止命令に基づく運転状態の変更を実行するか否かを選択させる通知が端末装置３０に供給され、ユーザによって運転停止を実行する操作が行われた場合に限って、室内に人がいる状態において空気調和機１の運転が停止される。 Further, in the air conditioner 1 of the present embodiment, in the absence notification mode, when the operation stop command is supplied from the terminal device 30 in a state in which a person in the room is detected by the human detection sensor 25, the operation stop command In response, a confirmation notification is supplied to the terminal device 30. Confirmation notification for the operation stop instruction includes, for example, information indicating that there is a person in the room, such as "Do you have a person in the room, but do you want to stop the operation of the air conditioner?" Is supplied to the terminal device 30 of the user and displayed on the display screen of the terminal device 30. At this time, on the display screen, along with this confirmation notification, a selection unit (not shown) that allows the user to select whether or not to execute the operation stop based on the operation stop command is displayed. Therefore, the user performs an operation for executing the operation stop or an operation for not executing the operation stop on the terminal device 30. Thus, in this embodiment, when the user supplies an operation stop command to the air conditioner 1 from the terminal device 30 in a state where a person in the room is detected, the change of the operation state based on the operation stop command is performed. The operation of the air conditioner 1 is stopped in a state where there is a person in the room only when a notification for selecting whether or not to execute the operation is supplied to the terminal device 30 and an operation for executing the operation stop is performed by the user. Is done.
　次に、空気調和機１の不在お知らせモードにおける制御について、図３を参照しつつ説明する。 Next, control in the absence notification mode of the air conditioner 1 will be described with reference to FIG.
　まず、空気調和機１の運転停止時において、コントローラ３０のモード切換部によって、不在お知らせモード（高温防止モードの切）に切り換えられる（ステップＳ１）。 First, when the operation of the air conditioner 1 is stopped, the mode switching unit of the controller 30 switches to the absence notification mode (high temperature prevention mode off) (step S1).
　不在お知らせモードにおいて、人検知センサ２５によって室内にいる人が検知されない状態であるかを繰り返し判断する（ステップＳ２）。人検知センサ２５によって室内にいる人が検知されない状態であると判断した場合には（ステップＳ２：ＹＥＳ）、人検知センサ２５によって室内にいる人が検知されない状態において、空気調和機１の運転が所定の不在時間だけ継続されたかを判断する（ステップＳ３）。空気調和機１の運転が所定の不在時間だけ継続されたと判断した場合には（ステップＳ３：ＹＥＳ）、室内に人がいないことを示す不在情報をユーザの端末装置３０に供給する。一方、空気調和機１の運転が所定の不在時間だけ継続されてないと判断した場合には（ステップＳ４：ＮＯ）、ステップＳ２に移行する。 In the absence notification mode, it is repeatedly determined whether or not a person in the room is not detected by the human detection sensor 25 (step S2). When it is determined that the person in the room is not detected by the human detection sensor 25 (step S2: YES), the operation of the air conditioner 1 is performed in a state in which the person in the room is not detected by the human detection sensor 25. It is determined whether or not the predetermined absence time has been continued (step S3). When it is determined that the operation of the air conditioner 1 has been continued for a predetermined absence time (step S3: YES), absence information indicating that there is no person in the room is supplied to the user terminal device 30. On the other hand, when it is determined that the operation of the air conditioner 1 is not continued for a predetermined absence time (step S4: NO), the process proceeds to step S2.
　不在情報をユーザの端末装置３０に供給した後、端末装置３０から運転停止命令が供給されたか（ユーザが端末装置３０を操作して運転停止操作を行ったか）を繰り返し判断する（ステップＳ５）。端末装置３０から運転停止命令が供給されたと判断した場合には（ステップＳ５：ＹＥＳ）、人検知センサ２５によって室内にいる人が検知される状態であるかを判断する（ステップＳ６）。人検知センサ２５によって室内にいる人が検知される状態であると判断した場合には（ステップＳ６：ＹＥＳ）、運転停止命令に対する確認通知として、空気調和機１の運転停止を実行するか否かを選択させる通知が端末装置３０に供給される（ステップＳ７）。その後、運転停止命令に対する確認通知が端末装置３０に供給された後で（ユーザが運転停止命令に対する確認通知を見た後で）、空気調和機１の運転停止を実行する操作を行ったかを繰り返し判断する（ステップＳ８）。ユーザが空気調和機１の運転停止を実行する操作を行ったと判断した場合には（ステップＳ８：ＹＥＳ）、空気調和機１の運転を停止する（ステップＳ９）。一方、ステップＳ６において、人検知センサ２５によって室内にいる人が検知されない状態であると判断した場合には（ステップＳ６：ＮＯ）、運転停止命令に対する確認通知が端末装置３０に供給されることなく、ステップＳ８に移行する。 After supplying the absence information to the terminal device 30 of the user, it is repeatedly determined whether an operation stop command is supplied from the terminal device 30 (whether the user has operated the terminal device 30 to perform the operation stop operation) (step S5). When it is determined that the operation stop command is supplied from the terminal device 30 (step S5: YES), it is determined whether or not a person in the room is detected by the human detection sensor 25 (step S6). When it is determined that the person in the room is detected by the human detection sensor 25 (step S6: YES), whether or not to stop the operation of the air conditioner 1 as a confirmation notification for the operation stop command is determined. Is sent to the terminal device 30 (step S7). After that, after the confirmation notification for the operation stop command is supplied to the terminal device 30 (after the user sees the confirmation notification for the operation stop command), it is repeated whether the operation for executing the operation stop of the air conditioner 1 has been performed. Judgment is made (step S8). If it is determined that the user has performed an operation to stop the operation of the air conditioner 1 (step S8: YES), the operation of the air conditioner 1 is stopped (step S9). On the other hand, in step S6, when it is determined that the person in the room is not detected by the human detection sensor 25 (step S6: NO), a confirmation notification for the operation stop command is not supplied to the terminal device 30. The process proceeds to step S8.
