Further, it is assumed that there is no shielding object between the human sensor 3 and the user 5 so that the human sensor 3 cannot detect the user 5.
　図２は、実施の形態１にかかるマイクロコンピュータ１００の構成を示すブロック図である。マイクロコンピュータ１００は、演算および空気調和機１０の制御を実行するＣＰＵ（Ｃｅｎｔｒａｌ　Ｐｒｏｃｅｓｓｉｎｇ　Ｕｎｉｔ）１０１と、ＣＰＵ１０１がワークエリアに用いるＲＡＭ（Ｒａｎｄｏｍ　Ａｃｃｅｓｓ　Ｍｅｍｏｒｙ）１０２と、プログラムおよびデータを記憶するＲＯＭ（Ｒｅａｄ　Ｏｎｌｙ　Ｍｅｍｏｒｙ）１０３と、人感センサ３と信号をやりとりするハードウェアであるＩ／Ｏ（Ｉｎｐｕｔ／Ｏｕｔｐｕｔ）１０４と、クロックを生成する発振子を含む周辺装置１０５と、を備える。 FIG. 2 is a block diagram of the configuration of the microcomputer 100 according to the first embodiment. The microcomputer 100 includes a CPU (Central Processing Unit) 101 that executes calculation and control of the air conditioner 10, a RAM (Random Access Memory) 102 that the CPU 101 uses as a work area, and a ROM (Read Only) that stores programs and data. (Memory) 103, I / O (Input / Output) 104 that is hardware for exchanging signals with the human sensor 3, and a peripheral device 105 including an oscillator that generates a clock.
　図３は、実施の形態１にかかるマイクロコンピュータ１００によるソフトウェア制御の仕様を示す説明図である。マイクロコンピュータ１００による制御の仕様は、ＲＯＭ１０３またはその他の箇所に記憶されるプログラムすなわちソフトウェアにより規定される。 FIG. 3 is an explanatory diagram of software control specifications performed by the microcomputer 100 according to the first embodiment. The specification of control by the microcomputer 100 is defined by a program stored in the ROM 103 or other portions, that is, software.
　図３に示すように、マイクロコンピュータ１００がプログラムを実行することにより、ユーザーによる設定情報２０、室温及び湿度情報１３および人感センサ情報１４に基づいて、暖房運転により不快な環境を作るための不快運転モード１５、ユーザーによる起床時間の設定を含んだ後述する起床タイマー設定を受け付けるタイマー機能１６、およびユーザーの睡眠状態を判定するための睡眠状態検知モード１７を実現する。 As shown in FIG. 3, when the microcomputer 100 executes the program, it is uncomfortable for creating an uncomfortable environment by heating operation based on the setting information 20, the room temperature and humidity information 13 and the human sensor information 14 by the user. An operation mode 15, a timer function 16 that accepts a wake-up timer setting described later including a wake-up time setting by the user, and a sleep state detection mode 17 for determining the user's sleep state are realized.
　ユーザーによる設定情報２０は、室内機２の図示していないリモートコントローラを介してユーザー５により設定される情報であって、起床予定時刻１１および睡眠状態検知モードの継続時間１２を含んでいる。室温及び湿度情報１３は、図示していない室内機２の室温センサおよび湿度センサにより取得される部屋１の室温及び湿度の情報である。人感センサ情報１４は、人感センサ３が取得した上述した検知結果のデータである。 The setting information 20 by the user is information set by the user 5 via a remote controller (not shown) of the indoor unit 2 and includes a scheduled wake-up time 11 and a duration 12 of the sleep state detection mode. The room temperature and humidity information 13 is the room temperature and humidity information of the room 1 acquired by the room temperature sensor and humidity sensor of the indoor unit 2 (not shown). The human sensor information 14 is the above-described detection result data acquired by the human sensor 3.
　ユーザー５によって設定される起床予定時刻１１および睡眠状態検知モードの継続時間１２に基づいて、睡眠状態検知モード１７、タイマー機能１６および不快運転モード１５の３つの機能が動作することで、空気調和機１０は不快モードの暖房運転を行うことが可能となる。不快運転モード１５は睡眠状態検知モード１７の下で実行されるモードであり、マイクロコンピュータ１００は、不快運転モード１５において空気調和機１０すなわち室内機２および室外機４を制御して不快モードの暖房運転を行わせる。 The air conditioner is operated by three functions of the sleep state detection mode 17, the timer function 16, and the uncomfortable driving mode 15 based on the scheduled wake-up time 11 set by the user 5 and the duration 12 of the sleep state detection mode. 10 can perform the heating operation in an unpleasant mode. The unpleasant driving mode 15 is a mode executed under the sleep state detection mode 17, and the microcomputer 100 controls the air conditioner 10, that is, the indoor unit 2 and the outdoor unit 4 in the unpleasant driving mode 15, and performs heating in the unpleasant mode. Let's drive.
　不快モードは人が不快と感じる不快環境を作るモードである。不快環境は、具体的には、不快指数に基づいて人が不快と感じる環境を導き出して、その環境に対応する温度および湿度といった設定データを用いて設定される。不快指数は、温度と湿度の２つのパラメータから人が不快と感じる環境を導いた指数であり、部屋１の湿度を計測することにより、当該湿度において不快指数が高くなる温度を導くことができる。ここで、不快環境とは、室内機２の湿度センサが測定した部屋１の湿度において、不快指数が予め定めた閾値以上となるような室温の環境であるとする。そして、不快モードの暖房運転は、部屋１の湿度において不快環境となるような室温を目標とする暖房運転であるとする。 Discomfort mode is a mode that creates an uncomfortable environment where people feel uncomfortable. Specifically, the unpleasant environment is set using setting data such as temperature and humidity corresponding to the environment by deriving an environment in which a person feels unpleasant based on the discomfort index. The discomfort index is an index derived from an environment in which a person feels uncomfortable from two parameters, temperature and humidity, and by measuring the humidity of the room 1, a temperature at which the discomfort index increases at the humidity can be derived. Here, the uncomfortable environment is assumed to be an environment at room temperature in which the discomfort index is equal to or higher than a predetermined threshold in the humidity of the room 1 measured by the humidity sensor of the indoor unit 2. The heating operation in the unpleasant mode is assumed to be a heating operation targeting a room temperature that causes an uncomfortable environment in the humidity of the room 1.
　人は高温多湿の環境下では簡単には眠りにつくことができない。したがって、ユーザー５が睡眠している部屋１の居室の温度すなわち室温を高くして、ユーザー５が不快と感じる環境に空気調和機１０が調整することで、ユーザー５が睡眠状態を維持することまたは再び眠ることを困難にできる。 People cannot fall asleep easily in a hot and humid environment. Therefore, the temperature of the living room of the room 1 where the user 5 is sleeping, that is, the room temperature is increased, and the air conditioner 10 adjusts to an environment in which the user 5 feels uncomfortable, so that the user 5 maintains the sleeping state or It can make it difficult to sleep again.
　次に、実施の形態１にかかる空気調和機１０の動作について説明する。図４は、実施の形態１にかかる空気調和機１０の動作を説明するフローチャートである。なお、このフローチャートにおけるマイクロコンピュータ１００の動作は、マイクロコンピュータ１００がプログラムを実行することにより実行される。 Next, the operation of the air conditioner 10 according to the first embodiment will be described. FIG. 4 is a flowchart for explaining the operation of the air conditioner 10 according to the first embodiment. The operation of the microcomputer 100 in this flowchart is executed by the microcomputer 100 executing a program.
　まず、リモートコントローラを操作することによりユーザー５が設定する起床予定時刻１１および睡眠状態検知モードの継続時間１２といったユーザーによる設定情報２０をマイクロコンピュータ１００が受け付ける（ステップＳ１）。起床予定時刻１１および睡眠状態検知モードの継続時間１２の設定を、起床タイマー設定と呼ぶ。すなわち、ステップＳ１では、起床タイマー設定が受け付けられる。ユーザー５は、就寝前といった起床予定時刻１１の前に起床タイマー設定を行う。なお、睡眠状態検知モードの継続時間１２は予め設定されていて、起床タイマー設定において、ユーザー５は起床予定時刻１１のみを設定するようにしてもよい。 First, the microcomputer 100 receives setting information 20 by the user such as the scheduled wake-up time 11 and the duration 12 of the sleep state detection mode set by the user 5 by operating the remote controller (step S1). The setting of the scheduled wake-up time 11 and the duration 12 of the sleep state detection mode is referred to as a wake-up timer setting. That is, in step S1, a wake-up timer setting is accepted. The user 5 sets the wake-up timer before the scheduled wake-up time 11 such as before going to bed. The duration 12 of the sleep state detection mode is set in advance, and the user 5 may set only the scheduled wake-up time 11 in the wake-up timer setting.
　そして、マイクロコンピュータ１００は、空気調和機１０に起床予定時刻１１より設定時間だけ前に睡眠状態検知モード１７を開始させる（ステップＳ２）。マイクロコンピュータ１００は、具体的には、睡眠状態検知モード１７の開始により人感センサ３の動作を開始させる。睡眠状態検知モード１７が開始されるのは、起床予定時刻１１より設定時間だけ前、具体例としては５分前に睡眠状態検知モード１７が開始される。睡眠状態検知モード１７が起床予定時刻１１よりどれくらいの設定時間だけ前から開始されるかについては、予め定められているか、またはユーザー５がリモートコントローラを操作して設定してもよく、５分に限定されず、１０分その他の所望の値にすることができる。なお、上記では、睡眠状態検知モード１７である期間の間に起床予定時刻１１が含まれるとしたが、場合によっては、睡眠状態検知モード１７の開始を起床予定時刻１１の後に設定してもよい。 Then, the microcomputer 100 causes the air conditioner 10 to start the sleep state detection mode 17 only a set time before the scheduled wake-up time 11 (step S2). Specifically, the microcomputer 100 starts the operation of the human sensor 3 by starting the sleep state detection mode 17. The sleep state detection mode 17 is started by a set time before the scheduled wake-up time 11, and specifically, the sleep state detection mode 17 is started 5 minutes before. It is predetermined or how long the sleep state detection mode 17 is started from the scheduled time 11 before the scheduled wake-up time 11 or may be set by the user 5 operating the remote controller. It is not limited and can be 10 minutes or any other desired value. In the above description, it is assumed that the scheduled wake-up time 11 is included in the period of the sleep state detection mode 17, but in some cases, the start of the sleep state detection mode 17 may be set after the scheduled wake-up time 11. .
　その後、マイクロコンピュータ１００は、人感センサ３が取得した人感センサ情報１４に基づいて、ユーザー５が睡眠状態であるか否かを判定する（ステップＳ３）。判定方法の具体例としては、ユーザー５が横になっている状態を人感センサ情報１４が示しているならば、マイクロコンピュータ１００は、ユーザー５が睡眠状態であると判定し、ユーザー５が立ち上がっている状態または座った状態で活動している状態を人感センサ情報１４が示しているならば、マイクロコンピュータ１００は、ユーザー５が睡眠状態ではなく起床状態であると判定する。 Thereafter, the microcomputer 100 determines whether or not the user 5 is in a sleep state based on the human sensor information 14 acquired by the human sensor 3 (step S3). As a specific example of the determination method, if the human sensor information 14 indicates that the user 5 is lying down, the microcomputer 100 determines that the user 5 is in a sleep state, and the user 5 starts up. If the human sensor information 14 indicates a sitting state or an active state while sitting, the microcomputer 100 determines that the user 5 is not in a sleeping state but in a rising state.
　ステップＳ３において、起床予定時刻１１の上記した設定時間だけ前においてユーザー５が睡眠状態であると判定されれば（ステップＳ３：Ｙｅｓ）、マイクロコンピュータ１００は不快運転モード１５になって、空気調和機１０、すなわち室内機２および室外機４に不快モードの暖房運転を開始させて（ステップＳ４）、部屋１をユーザー５が眠り続けにくい不快環境にする。具体的には、室内機２の湿度センサが測定した部屋１の湿度において、不快指数が予め定めた閾値となる第一温度に部屋１の室温がなるように、マイクロコンピュータ１００は、室内機２および室外機４を制御して暖房運転を実行させる。 In step S3, if it is determined that the user 5 is in a sleep state just before the set time before the scheduled wake-up time 11 (step S3: Yes), the microcomputer 100 enters the uncomfortable operation mode 15, and the air conditioner 10, i.e., the indoor unit 2 and the outdoor unit 4 start the heating operation in the unpleasant mode (step S4), and the room 1 is made an unpleasant environment in which the user 5 hardly keeps sleeping. Specifically, the microcomputer 100 includes the indoor unit 2 so that the room temperature of the room 1 becomes the first temperature at which the discomfort index is a predetermined threshold in the humidity of the room 1 measured by the humidity sensor of the indoor unit 2. And the outdoor unit 4 is controlled and heating operation is performed.
　ユーザー５が睡眠状態ではなく起床状態であると判定されれば（ステップＳ３：Ｎｏ）、マイクロコンピュータ１００は室内機２および室外機４を運転停止状態にするか、またはユーザー５が設定した運転状態にする（ステップＳ５）。したがって、起床予定時刻１１の上記した設定時間だけ前においてユーザー５が起床状態であると判定された場合は、マイクロコンピュータ１００は室内機２および室外機４に運転停止状態を保たせるか、またはユーザー５が設定した運転状態を新たに開始させることになる。 If it is determined that the user 5 is not in the sleep state but is in the wake-up state (step S3: No), the microcomputer 100 puts the indoor unit 2 and the outdoor unit 4 into the operation stop state or the operation state set by the user 5 (Step S5). Therefore, when it is determined that the user 5 is in the wake-up state only before the set time before the scheduled wake-up time 11, the microcomputer 100 causes the indoor unit 2 and the outdoor unit 4 to keep the operation stopped or the user 5 The operation state set by 5 is newly started.
　ステップＳ４およびステップＳ５の後、マイクロコンピュータ１００は、睡眠状態検知モード１７になってから睡眠状態検知モードの継続時間１２を経たか否かを判定する（ステップＳ６）。そして、睡眠状態検知モード１７になってから睡眠状態検知モードの継続時間１２を経ていない限り（ステップＳ６：Ｎｏ）、ユーザー５が睡眠状態であるか否かの判定（ステップＳ３）が繰り返される。 After step S4 and step S5, the microcomputer 100 determines whether or not the duration 12 of the sleep state detection mode has elapsed since the sleep state detection mode 17 was entered (step S6). And unless it has passed the continuation time 12 of sleep state detection mode after becoming sleep state detection mode 17 (step S6: No), determination (step S3) whether the user 5 is a sleep state is repeated.
　その結果、睡眠状態検知モード１７になってから睡眠状態検知モードの継続時間１２を経ていない限り（ステップＳ６：Ｎｏ）、不快モードの暖房運転は、ユーザー５が起床状態であると室内機２のマイクロコンピュータ１００が判定する（ステップＳ３：Ｎｏ）まで継続される。また、ユーザー５が一度起床状態であると判定され（ステップＳ３：Ｎｏ）、不快運転モード１５を終了した場合であっても、その後、睡眠状態検知モード１７が継続している間に、ユーザー５が再び睡眠してしまった場合には、人感センサ３からの人感センサ情報１４に基づいて、マイクロコンピュータ１００はユーザー５が睡眠状態であると判定して（ステップＳ３：Ｙｅｓ）、不快運転モード１５になって不快モードの暖房運転（ステップＳ４）が再度開始される。 As a result, unless the sleep state detection mode duration 12 has passed since the sleep state detection mode 17 was entered (step S6: No), the heating operation in the unpleasant mode is performed when the user 5 is in the wake-up state. The process continues until the microcomputer 100 determines (No at Step S3). Further, even if it is determined that the user 5 is once in the wake-up state (step S3: No) and the uncomfortable driving mode 15 is terminated, the user 5 remains in the state where the sleep state detection mode 17 continues thereafter. If the user sleeps again, based on the human sensor information 14 from the human sensor 3, the microcomputer 100 determines that the user 5 is in the sleep state (step S3: Yes), and uncomfortable driving. It becomes mode 15 and the heating operation in the unpleasant mode (step S4) is started again.
　睡眠状態検知モード１７になってから睡眠状態検知モードの継続時間１２を経た場合は（ステップＳ６：Ｙｅｓ）、マイクロコンピュータ１００は人感センサ３の動作を停止させて（ステップＳ７）、睡眠状態検知モード１７を終了させる。なお、睡眠状態検知モード１７になってから睡眠状態検知モードの継続時間１２を経たときに、不快運転モード１５であったときは、マイクロコンピュータ１００は、睡眠状態検知モード１７と共に不快運転モード１５も解除して空気調和機１０に不快モードの暖房運転を終了させる。 When the sleep state detection mode 17 has elapsed and the duration 12 of the sleep state detection mode has elapsed (step S6: Yes), the microcomputer 100 stops the operation of the human sensor 3 (step S7) and detects the sleep state. Mode 17 is terminated. If the sleep state detection mode 17 is followed by the sleep state detection mode duration 12 and the uncomfortable driving mode 15 is reached, the microcomputer 100 also sets the unpleasant driving mode 15 together with the sleep state detection mode 17. The air conditioner 10 is released and the heating operation in the unpleasant mode is terminated.
　図５は、実施の形態１にかかる空気調和機１０の動作を説明するタイミングチャートである。図５に示すように、ユーザー５が、６：００を起床予定時刻１１と設定した場合（図４のステップＳ１）、起床予定時刻１１である６：００の５分前の５：５５から空気調和機１０は睡眠状態検知モード１７がＯＮになって開始される（ステップＳ２）と共に不快モードの暖房運転（ステップＳ４）を開始する。より詳細には、５：５５に睡眠状態検知モード１７になる（ステップＳ２）と、ただちにユーザー５が睡眠状態であるか否かが判定され（ステップＳ３）、ユーザー５がまだ寝ている場合は、ユーザー５が睡眠状態であると判定されて（ステップＳ３：Ｙｅｓ）、睡眠状態検知判定値が未判定状態から睡眠状態を示す値になる。その結果、不快運転モード１５になり空気調和機１０の運転がＯＮになって５：５５から不快モードの暖房運転（ステップＳ４）が開始される。 FIG. 5 is a timing chart for explaining the operation of the air conditioner 10 according to the first embodiment. As shown in FIG. 5, when the user 5 sets 6:00 as the scheduled wake-up time 11 (step S <b> 1 in FIG. 4), the air starts at 5:55 5 minutes before 6:00, which is the planned wake-up time 11. The harmony machine 10 starts when the sleep state detection mode 17 is turned on (step S2) and starts the heating operation in the unpleasant mode (step S4). More specifically, when the sleep state detection mode 17 is entered at 5:55 (step S2), it is immediately determined whether or not the user 5 is in a sleep state (step S3). If the user 5 is still sleeping, Then, it is determined that the user 5 is in the sleep state (step S3: Yes), and the sleep state detection determination value becomes a value indicating the sleep state from the undecided state. As a result, the unpleasant operation mode 15 is entered, the operation of the air conditioner 10 is turned on, and the unpleasant mode heating operation (step S4) is started from 5:55.
　５：５５に空気調和機１０が不快モードの暖房運転（ステップＳ４）を開始したことにより部屋１の室温は上昇し、起床予定時刻１１である６：００には部屋１の室温は第一温度になって部屋１は不快環境になる。ユーザー５が眠る部屋１が不快環境となったことで、６：１０にユーザー５が起床して起き上がることで、起床状態であると判定されれば（ステップＳ３：Ｎｏ）、空気調和機１０は運転停止状態（ＯＦＦ）になって不快モードの暖房運転が終了するか、または図５では示さないがユーザー５が設定した運転状態を開始する（ステップＳ５）。 At 5:55, the air conditioner 10 starts the heating operation in the uncomfortable mode (step S4), and the room temperature of the room 1 rises. At 6:00, which is the scheduled wake-up time 11, the room temperature of the room 1 is the first temperature. The room 1 becomes an uncomfortable environment. If the room 1 in which the user 5 sleeps becomes an uncomfortable environment and the user 5 wakes up and gets up at 6:10 and is determined to be in the wake-up state (step S3: No), the air conditioner 10 The operation is stopped (OFF) and the heating operation in the uncomfortable mode is completed, or the operation state set by the user 5 is started although not shown in FIG. 5 (step S5).
　しかしその後、ユーザーが６：２５に二度寝に入ることによって、再びマイクロコンピュータ１００に睡眠状態であると判断された場合（ステップＳ３：Ｙｅｓ）には、再び不快モードの暖房運転（ステップＳ４）が開始されることとなる。二度目の不快モードの暖房運転が行われた結果、その後６：３５の時点でユーザー５が起床して起き上がると、起床状態であると判定されて（ステップＳ３：Ｎｏ）、空気調和機１０は運転停止状態（ＯＦＦ）になって不快モードの暖房運転が終了する。 However, after that, when the user goes to sleep twice at 6:25, and it is determined again that the microcomputer 100 is in a sleep state (step S3: Yes), the heating operation in the unpleasant mode is again performed (step S4). Will be started. As a result of the heating operation in the second unpleasant mode, when the user 5 gets up and gets up at 6:35, it is determined that the user 5 is in the rising state (step S3: No), and the air conditioner 10 The operation is stopped (OFF), and the heating operation in the unpleasant mode ends.
　以上述べたように、睡眠状態検知モード１７が続いている間は、ユーザー５が何度寝直しをしても不快モードの暖房運転を繰り返すように空気調和機１０を制御することにより、ユーザー５が快適な睡眠をとれない環境を作り出す。不快モードの暖房運転を終了させるためには、ユーザー５が起床して行動し続けるか、リモートコントローラを操作することにより起床タイマー設定を解除する必要がある。ボタン一つの操作ではなく、複数の操作をしなければ起床タイマー設定の変更をできないようなリモートコントローラの仕様とすることで、ユーザー５が睡眠状態もしくは半分眠った状態で起床タイマー設定を解除することが困難なものとする。これにより、ユーザー５が確実に起きるまで不快環境が継続することとなり、二度寝といった寝直しによるユーザー５の寝坊のリスクを大幅に低減することができる。 As described above, while the sleep state detection mode 17 continues, by controlling the air conditioner 10 so that the heating operation in the unpleasant mode is repeated even if the user 5 sleeps many times, the user 5 Creates a comfortable sleep environment. In order to end the heating operation in the unpleasant mode, it is necessary for the user 5 to wake up and continue to act or to cancel the wake-up timer setting by operating a remote controller. Releasing the wake-up timer setting when the user 5 is asleep or half-sleep by adopting a remote controller specification that cannot change the wake-up timer setting without a single button operation Is difficult. As a result, the uncomfortable environment continues until the user 5 surely wakes up, and the risk of oversleeping of the user 5 due to bedtime such as sleeping twice can be greatly reduced.
　以上説明したように、ユーザー５が起きたいと考えている起床予定時刻１１に空気調和機１０が不快モードの暖房運転を行うことにより、ユーザー５が一度目覚めた後で寝直しをしたいと思わせないような不快環境をつくることができる。また、もしユーザー５が寝直しをしてしまった場合でも、部屋１を再度不快環境にすることでユーザー５が深く寝付くことができない状態を保つことができる。これにより、ユーザー５が起床予定時刻１１に対して大幅な寝坊をすることを予防することが可能となる。さらに、室内機２のマイクロコンピュータ１００がユーザーの起床を判定する機能を備えているので、不快運転モード１５を解除することが可能である。 As described above, when the air conditioner 10 performs the heating operation in the unpleasant mode at the scheduled wake-up time 11 when the user 5 wants to wake up, the user 5 wants to sleep again after waking up once. An uncomfortable environment can be created. Moreover, even if the user 5 falls asleep, the state in which the user 5 cannot sleep deeply can be maintained by making the room 1 an uncomfortable environment again. As a result, it is possible to prevent the user 5 from overly sleeping with respect to the scheduled wake-up time 11. Furthermore, since the microcomputer 100 of the indoor unit 2 has a function of determining the user's wake-up, the uncomfortable operation mode 15 can be canceled.
実施の形態２．
　実施の形態２にかかる空気調和機１０の配置は図１と同じであり、実施の形態２にかかるマイクロコンピュータ１００の構成は図２と同じである。図６は、実施の形態２にかかるマイクロコンピュータ１００によるソフトウェア制御の仕様を示す説明図である。図６では、曜日毎の予め定めた時間にタイマー機能１６が働くように設定できるウィークリータイマー機能１８が図３に追加されている。マイクロコンピュータ１００がプログラムを実行することにより、ウィークリータイマー機能１８が実現される。ウィークリータイマー機能１８以外の構成は、実施の形態１で説明した図３と同じであるので説明を省略する。実施の形態２にかかる空気調和機１０は、ユーザー５が曜日毎の予め定めた時間に起床する場合に対応することができる。 Embodiment 2. FIG.
The arrangement of the air conditioner 10 according to the second embodiment is the same as that in FIG. 1, and the configuration of the microcomputer 100 according to the second embodiment is the same as that in FIG. FIG. 6 is an explanatory diagram of software control specifications performed by the microcomputer 100 according to the second embodiment. In FIG. 6, a weekly timer function 18 that can be set so that the timer function 16 works at a predetermined time for each day of the week is added to FIG. When the microcomputer 100 executes the program, the weekly timer function 18 is realized. The configuration other than the weekly timer function 18 is the same as that in FIG. The air conditioner 10 according to the second embodiment can cope with a case where the user 5 gets up at a predetermined time for each day of the week.
　図６に示すように、ウィークリータイマー機能１８を実装することで、ユーザー５は、曜日毎に起床予定時刻１１を設定することができる。ウィークリータイマー機能１８を使うことで、曜日毎の起床予定時刻１１および睡眠状態検知モードの継続時間１２をユーザー５が一度設定すれば、毎日起床タイマー設定をしなくても、曜日毎の起床予定時刻１１になると空気調和機１０に不快モードの暖房運転をさせることが可能となる。従って、実施の形態２にかかる空気調和機１０の動作においては、図４のステップＳ１をウィークリータイマー機能１８を用いて一度実行すれば、ステップＳ１を毎晩実行することは不要となり、図４のステップＳ２からＳ７が曜日毎の起床タイマー設定に基づいて毎日実行されることになる。 As shown in FIG. 6, by installing the weekly timer function 18, the user 5 can set the scheduled wake-up time 11 for each day of the week. By using the weekly timer function 18, if the user 5 once sets the scheduled wake-up time 11 for each day of the week and the duration 12 of the sleep state detection mode, the scheduled wake-up time for each day of the week may be set without setting the wake-up timer every day. When it becomes 11, it becomes possible to make the air conditioner 10 perform heating operation in an unpleasant mode. Therefore, in the operation of the air conditioner 10 according to the second embodiment, if step S1 of FIG. 4 is executed once using the weekly timer function 18, it is not necessary to execute step S1 every night, and step of FIG. S2 to S7 are executed every day based on the wake-up timer setting for each day of the week.
　また、実施の形態２にかかる空気調和機１０は、実施の形態１と同様にユーザー５が起床することまたは睡眠状態検知モード１７になってから睡眠状態検知モードの継続時間１２を経たことにより、空気調和機１０に不快モードの暖房運転を停止させることができる。従って、ウィークリータイマー機能１８を利用して、曜日毎の起床タイマー設定をユーザー５が一度設定してしまえば、設定を変更する必要がない。その結果、ユーザー５が睡眠をとる前に起床タイマー設定を忘れることによって、不快モードの暖房運転が実施されずにユーザー５が寝坊することを防ぐことができる。 In addition, the air conditioner 10 according to the second embodiment has the continuation time 12 of the sleep state detection mode after the user 5 gets up or becomes the sleep state detection mode 17 as in the first embodiment. The air conditioner 10 can stop the heating operation in the unpleasant mode. Therefore, once the user 5 sets the wake-up timer setting for each day of the week using the weekly timer function 18, it is not necessary to change the setting. As a result, by forgetting the wake-up timer setting before the user 5 sleeps, the user 5 can be prevented from falling asleep without performing the heating operation in the unpleasant mode.
実施の形態３．
　実施の形態１および２では、不快モードの暖房運転により部屋１に実現する不快環境を１つのみ設定していたが、実施の形態３にかかる空気調和機１０では複数の不快環境を設ける。すなわち、室温を変えた複数の不快環境を設けることにより不快環境の段階を作り、最初の不快環境より更に不快な不快環境を設けることで、ユーザー５が更に起床し易くすることができる。実施の形態３にかかる空気調和機１０の動作を説明するフローチャートも基本的には図４と同様であるが、以下に説明するように初の不快環境から更に不快な不快環境への移行が追加される。 Embodiment 3 FIG.
In the first and second embodiments, only one unpleasant environment realized in the room 1 by the heating operation in the unpleasant mode is set. However, the air conditioner 10 according to the third embodiment provides a plurality of unpleasant environments. That is, by providing a plurality of unpleasant environments at different room temperatures, a stage of unpleasant environments is created, and by providing an unpleasant environment that is more unpleasant than the initial unpleasant environment, the user 5 can be more easily woken up. The flowchart for explaining the operation of the air conditioner 10 according to the third embodiment is also basically the same as that in FIG. 4, but a transition from the first unpleasant environment to a more unpleasant unpleasant environment is added as described below. Is done.
　以下では、室内機２の湿度センサが測定した部屋１の湿度において、不快指数が不快指数１となるような室温が第一温度の環境を不快環境１とし、不快指数が不快指数２となるような室温が第二温度の環境を不快環境２とする。不快指数１より不快指数２は大きく、共に予め定めた不快指数の閾値である。不快環境１は、起床予定時刻１１における不快環境である。 In the following, in the humidity of the room 1 measured by the humidity sensor of the indoor unit 2, the environment in which the room temperature is the first temperature at which the discomfort index is 1 is the discomfort environment 1, and the discomfort index is 2 An environment where the room temperature is the second temperature is defined as an unpleasant environment 2. The discomfort index 2 is larger than the discomfort index 1, and both are threshold values for a predetermined discomfort index. The unpleasant environment 1 is an unpleasant environment at the scheduled wake-up time 11.
　図７は、実施の形態３にかかる空気調和機１０の動作を説明するタイミングチャートである。図７に示すように、ユーザー５が、６：００を起床予定時刻１１と設定した場合（図４のステップＳ１）、起床予定時刻１１である６：００の５分前の５：５５に睡眠状態検知モード１７になる（ステップＳ２）と、ただちにユーザー５が睡眠状態であるか否かが判定され（ステップＳ３）、ユーザー５がまだ寝ている場合は、ユーザー５が睡眠状態であると判定されて（ステップＳ３：Ｙｅｓ）、睡眠状態検知判定値が未判定状態から睡眠状態を示す値になる。その結果、不快運転モード１５になり空気調和機１０の運転がＯＮになって５：５５から不快モードの暖房運転（ステップＳ４）が開始される。 FIG. 7 is a timing chart for explaining the operation of the air conditioner 10 according to the third embodiment. As shown in FIG. 7, when the user 5 sets 6:00 as the scheduled wake-up time 11 (step S <b> 1 in FIG. 4), the user 5 sleeps at 5:55 5 minutes before 6:00, which is the scheduled wake-up time 11. When the state detection mode 17 is entered (step S2), it is immediately determined whether or not the user 5 is sleeping (step S3). If the user 5 is still sleeping, it is determined that the user 5 is sleeping. (Step S3: Yes), the sleep state detection determination value changes from the undecided state to the value indicating the sleep state. As a result, the unpleasant operation mode 15 is entered, the operation of the air conditioner 10 is turned on, and the unpleasant mode heating operation (step S4) is started from 5:55.
　５：５５に空気調和機１０が不快モードの暖房運転（ステップＳ４）を開始したことにより部屋１の室温は上昇し、起床予定時刻１１である６：００には部屋１の室温は第一温度になり、部屋１は不快環境１になる。しかしその後、不快運転モード１５になって空気調和機１０が不快モードの暖房運転を開始してから一定時間が経過した６：１０になってもユーザー５が起床せず継続して睡眠状態と判定されたので（ステップＳ３：Ｙｅｓ）、マイクロコンピュータ１００は、さらに不快指数が大きな環境である１段階上の不快環境２になるように不快モードの暖房運転の目標とする設定室温を第二温度に上昇させる。すなわち、マイクロコンピュータ１００は、不快モードの暖房運転の目標とする室温を不快環境１の第一温度より数℃高い第二温度に上昇させる。このように、マイクロコンピュータ１００は、ユーザー５が起床せず継続して睡眠状態である期間が一定時間以上になったと判定した場合に、不快指数が不快指数２となるような第二温度を不快モードの暖房運転の室温の目標に変更する。上記一定時間は、ユーザー５があらかじめ設定してもよいしマイクロコンピュータ１００のプログラムにおいて設定されていてもよい。そして、６：１０から暫く経つと部屋１は不快環境２になりその環境が維持される。その結果、６：３５にはユーザー５が起床状態であると判定されたので（ステップＳ３：Ｎｏ）、空気調和機１０は運転停止状態（ＯＦＦ）になって不快モードの暖房運転が終了するか、または図７では示さないがユーザー５が設定した運転状態を開始する（ステップＳ５）。 At 5:55, the air conditioner 10 starts the heating operation in the uncomfortable mode (step S4), and the room temperature of the room 1 rises. At 6:00, which is the scheduled wake-up time 11, the room temperature of the room 1 is the first temperature. The room 1 becomes an uncomfortable environment 1. However, after that, the user 5 does not get up and is determined to be in a sleep state even after 6:10 when a certain time has elapsed since the air conditioner 10 started the heating operation in the unpleasant mode after entering the unpleasant operation mode 15. (Step S3: Yes), the microcomputer 100 sets the set room temperature, which is the target of the heating operation in the unpleasant mode, to the second temperature so that the uncomfortable environment 2 on the first stage, which is an environment having a larger discomfort index, is obtained. Raise. In other words, the microcomputer 100 raises the target room temperature for the heating operation in the unpleasant mode to a second temperature that is several degrees higher than the first temperature of the unpleasant environment 1. Thus, when the microcomputer 100 determines that the period during which the user 5 is continuously in a sleep state without getting up has reached a certain time or longer, the microcomputer 100 is uncomfortable with the second temperature at which the discomfort index becomes the discomfort index 2. Change to room temperature target for mode heating operation. The predetermined time may be set in advance by the user 5 or may be set in the program of the microcomputer 100. After a while from 6:10, the room 1 becomes an uncomfortable environment 2 and the environment is maintained. As a result, since it is determined that the user 5 is in the wake-up state at 6:35 (step S3: No), is the air conditioner 10 in the operation stop state (OFF) and is the heating operation in the unpleasant mode terminated? Or although not shown in FIG. 7, the driving | running state which the user 5 set is started (step S5).
　以上説明したように、実施の形態３にかかる空気調和機１０は、起床予定時刻１１よりも時間が経つほど徐々に部屋１をより高い室温の不快環境とすることで、起床予定時刻１１よりも時間が経つほどユーザー５にとっては不快で寝苦しく眠り続けることが困難な環境となっていくため、起床し易い状態となっていく。この結果、実施の形態１および２より、ユーザー５の寝坊のリスクをさらに低減することができる。 As described above, the air conditioner 10 according to the third embodiment gradually makes the room 1 an uncomfortable environment having a higher room temperature as time passes from the scheduled wake-up time 11, thereby making the air conditioner 10 higher than the scheduled wake-up time 11. As time passes, the environment becomes uncomfortable for the user 5 and it becomes difficult to stay asleep, so it becomes easier to get up. As a result, the risk of oversleeping of the user 5 can be further reduced than in the first and second embodiments.
　なお、上の説明では不快環境の段階を不快環境１および不快環境２の２段階として説明したが、不快指数の閾値を３以上設定すれば、それに応じて不快環境も３段階以上定義できるので、不快環境の段階を３段階以上にしてもかまわない。 In the above description, the stage of the unpleasant environment is described as two stages, the unpleasant environment 1 and the unpleasant environment 2. However, if the threshold of the unpleasant index is set to 3 or more, the unpleasant environment can be defined in three or more stages accordingly. There may be three or more stages of unpleasant environment.
