Description

空気調和機および空気調和機の制御方法Air conditioner and control method of air conditioner
　本発明は、携帯端末から操作することができる空気調和機および空気調和機の制御方法に関する。 The present invention relates to an air conditioner that can be operated from a portable terminal and a control method of the air conditioner.
　家庭などで使用される空気調和機は、リモートコントローラ（以下、リモコンと称する）を用いて遠隔操作される。一般的なリモコンは、赤外線通信を用いて空気調和機に操作信号を伝送しており、空気調和機を遠隔操作できる距離は限られている。近年では、スマートフォンなどの携帯端末を使用して空気調和機を遠隔操作することができるようになっている。この場合、空気調和機は、通信アダプタと、ルータなどの通信装置とを介して、無線ＬＡＮ（Local　Area　Network）などの無線通信方式を用いて携帯端末から操作信号を受信している。 Air conditioners used in homes and the like are remotely controlled using a remote controller (hereinafter referred to as a remote controller). A general remote control transmits an operation signal to the air conditioner using infrared communication, and the distance over which the air conditioner can be remotely controlled is limited. In recent years, it has become possible to remotely control the air conditioner using a portable terminal such as a smartphone. In this case, the air conditioner receives an operation signal from the portable terminal using a wireless communication method such as a wireless LAN (Local Area Network) via the communication adapter and a communication device such as a router.
　赤外線通信が指向性を有しており、リモコンを空気調和機の室内機に向けて操作する必要があるのに対して、無線ＬＡＮでは、使用するアンテナによっては指向性を有さない。このため、無線ＬＡＮを使用することによって指向性のない操作が可能となる。また無線ＬＡＮを使用することによって赤外線通信よりも遠距離からの操作が可能となり、空気調和機の室内機が設置されている室内だけでなく宅内の他の部屋から空気調和機を操作することができる。さらに通信装置が外部のネットワークと接続されている場合、サーバを介して、宅外から遠隔操作することも可能となる。また、Ｂｌｕｅｔｏｏｔｈ（登録商標）など無線ＬＡＮ以外の無線通信方式を用いた無線通信機能を搭載した空気調和機も市場で流通している。Ｂｌｕｅｔｏｏｔｈは、無線ＬＡＮよりも通信範囲は狭いが、無線ＬＡＮよりも低消費電力で動作することができ、ルータなどの通信装置を用いる必要がないという利点がある。 While infrared communication has directivity, and it is necessary to operate the remote control toward the indoor unit of the air conditioner, the wireless LAN does not have directivity depending on the antenna used. Therefore, non-directional operation is possible by using the wireless LAN. In addition, by using the wireless LAN, it is possible to operate from a longer distance than infrared communication, and it is possible to operate the air conditioner not only in the room where the indoor unit of the air conditioner is installed but also from other rooms in the house. it can. Furthermore, when the communication device is connected to an external network, remote control can be performed from outside the house via the server. In addition, air conditioners equipped with a wireless communication function using a wireless communication method other than a wireless LAN such as Bluetooth (registered trademark) are also distributed in the market. Bluetooth has a narrower communication range than a wireless LAN, but can operate with lower power consumption than a wireless LAN, and has the advantage that it is not necessary to use a communication device such as a router.
　特許文献１には、赤外線通信を用いて操作信号を受信する手元操作モードと、携帯端末から無線ＬＡＮなどの近距離無線通信を用いて操作信号を受信する遠方操作モードと、リモコンおよび携帯端末の両方から操作信号を受信する共用モードとを備える空気調和機が開示されている。 Patent Document 1 includes a hand operation mode for receiving an operation signal using infrared communication, a far operation mode for receiving an operation signal from a portable terminal using short distance wireless communication such as wireless LAN, a remote control, and a portable terminal.

The communication adapter 3 is externally attached to the indoor unit 1 in FIG. 1, but the present invention is not limited to this example. The communication adapter 3 may be built in the housing of the indoor unit 1. The communication adapter 3 monitors information of the mobile terminal 7 such as an operation mode of the mobile terminal 7.
　携帯端末７と通信装置４との間では、第１通信方式を用いた第１の宅内通信Ｃ３が行われる。携帯端末７と通信アダプタ３との間では、第２通信方式を用いた第２の宅内通信Ｃ２が行われる。携帯端末７は、第１の宅内通信Ｃ３を用いて、通信装置４を介して空気調和機１００に操作信号を伝送することができる。携帯端末７は、第２の宅内通信Ｃ２を用いて通信アダプタ３と直接接続することができ、空気調和機１００に操作信号を伝送することができる。 The first in-home communication C3 using the first communication method is performed between the portable terminal 7 and the communication device 4.

　以下、宅内において第１通信方式を用いて空気調和機１００を操作することを第１宅内操作と称する。また宅内において第２通信方式を用いて空気調和機１００を操作することを第２宅内操作と称する。第１宅内操作の操作範囲は、第１の宅内通信Ｃ３の通信範囲である。第２宅内操作の操作範囲は、第２の宅内通信Ｃ２の通信範囲である。第１の宅内通信Ｃ３の通信範囲は、第２の宅内通信Ｃ２の通信範囲よりも広い。 Hereinafter, operating the air conditioner 100 using the first communication method in the home will be referred to as first home operation. Further, operating the air conditioner 100 in the home using the second communication method is referred to as second home operation. The operation range of the first in-home operation is the communication range of the first in-home communication C3. The operation range of the second in-home operation is the communication range of the second in-home communication C2. The communication range of the first in-home communication C3 is wider than the communication range of the second in-home communication C2.
　通信装置４は、通信アダプタ３と直接接続することができると共に、インターネットなどのネットワーク５と接続されている。このため携帯端末７は、ネットワーク５を介して宅外から空気調和機１００を制御することも可能である。この場合、携帯端末７はネットワーク５との間で３Ｇ通信、ＬＴＥ（Long　Term　Evolution）通信などの広域通信を行い、サーバ６などに登録されている情報に基づいて、空気調和機１００を操作することができる。サーバ６に登録されている情報は、空気調和機１００を操作するためのユーザ毎の個別設定情報などであり、例えば、設定温度を含む。設定温度は、冷房、暖房、送風などの動作モード毎に設定されている。以下、宅外において携帯端末７から空気調和機１００を操作することを宅外操作と称し、宅外操作において用いられる無線通信を宅外通信Ｃ４と称する。 The communication device 4 can be directly connected to the communication adapter 3 and connected to a network 5 such as the Internet. Therefore, the portable terminal 7 can control the air conditioner 100 from outside the home via the network 5. In this case, the portable terminal 7 performs wide area communication such as 3G communication and LTE (Long Term Evolution) communication with the network 5, and operates the air conditioner 100 based on the information registered in the server 6 or the like. be able to. The information registered in the server 6 is, for example, individual setting information for each user for operating the air conditioner 100, and includes, for example, a set temperature. The set temperature is set for each operation mode such as cooling, heating, and blowing. Hereinafter, operating the air conditioner 100 from the portable terminal 7 outside the home is referred to as outside operation, and wireless communication used in the outside operation is referred to as outside communication C4.
　携帯端末７は、携帯電話、スマートフォン、タブレット端末などである。携帯端末７は、各種のアプリケーションプログラムをダウンロードして実行することができ、ユーザ８が操作するためのタッチパネルなどの操作部を備えている。携帯端末７は、空気調和機１００に対応するアプリケーションプログラムをダウンロードして実行することで、空気調和機１００を遠隔操作する機能を備えることができる。 The mobile terminal 7 is a mobile phone, a smartphone, a tablet terminal, or the like. The portable terminal 7 can download and execute various application programs, and includes an operation unit such as a touch panel for the user 8 to operate. The portable terminal 7 can have a function of remotely operating the air conditioner 100 by downloading and executing an application program corresponding to the air conditioner 100.
　図２は、図１に示す空気調和機１００の機能構成を示す図である。室内機１は、赤外線受信部１１と、送風部１２と、温湿度センサ部１３と、表示部１４と、人感検知部１５と、制御部１６とを有する。 FIG. 2 is a diagram showing a functional configuration of the air conditioner 100 shown in FIG. The indoor unit 1 includes an infrared receiving unit 11, a blowing unit 12, a temperature and humidity sensor unit 13, a display unit 14, a human feeling detection unit 15, and a control unit 16.
　赤外線受信部１１は、リモコン２から赤外線を受信し、赤外線通信を用いて伝送される操作信号を制御部１６に出力する。送風部１２は、制御部１６からの指示に従って動作し、室内に送風する。温湿度センサ部１３は、室内の温度および湿度を検知する。表示部１４は、室内機１の筐体の外表面に設けられたＬＥＤなどの発光部である。表示部１４は、ＬＥＤの発光状態、発光色などによって、空気調和機１００の運転モード、通信モードなどを示す。 The infrared receiving unit 11 receives an infrared ray from the remote control 2 and outputs an operation signal transmitted using infrared communication to the control unit 16. The blower 12 operates in accordance with an instruction from the controller 16 to blow air indoors. The temperature and humidity sensor unit 13 detects the temperature and humidity of the room. The display unit 14 is a light emitting unit such as an LED provided on the outer surface of the housing of the indoor unit 1. The display unit 14 indicates the operation mode, the communication mode, and the like of the air conditioner 100 according to the light emission state and the light emission color of the LED.
　人感検知部１５は、室内機１に設けられた人感センサ、または室内機１の外部に配置された人感センサの検知結果を受信する受信部である。人感検知部１５は、赤外線センサ、映像素子などの検知手段を用いて、検知空間内に人が存在するか否かを検知する。赤外線センサは、検知空間内の熱源を検知し、検知した熱源の形状および動作の有無に基づいて、この熱源が人間であるか物であるかを判定する。人感検知部１５は、映像素子を用いて撮影した映像から、検知空間内に人間が存在するか否かを判定してもよい。検知空間は、検知手段の検知範囲内の空間であって、赤外線センサ、映像素子などの検知手段を設置する位置によって変化する。検知手段は、空気調和機１００が空気の状態を調整する対象空間と検知空間とが重なるような位置に設置されることが望ましい。検知手段が映像素子であって、映像素子が空気調和機１００の筐体の前面に設けられている場合、検知空間は映像素子の撮像対象の空間となる。 The human feeling detection unit 15 is a reception unit that receives detection results of a human sensor provided in the indoor unit 1 or a human sensor provided outside the indoor unit 1. The human feeling detection unit 15 detects whether or not a person is present in the detection space using detection means such as an infrared sensor, a video element, and the like. The infrared sensor detects the heat source in the detection space, and determines whether the heat source is a human or an object based on the detected shape and operation of the heat source. The human feeling detection unit 15 may determine whether or not a human exists in the detection space from the image captured using the video element. The detection space is a space within the detection range of the detection means, and changes according to the position where the detection means such as an infrared sensor, an image element, etc. is installed. It is desirable that the detection means be installed at a position where the target space where the air conditioner 100 adjusts the state of air and the detection space overlap. When the detection means is a video element and the video element is provided on the front of the casing of the air conditioner 100, the detection space is a space to be imaged by the video element.
　制御部１６は、室内機１の動作を制御している。制御部１６は、赤外線受信部１１、送風部１２、温湿度センサ部１３、表示部１４、人感検知部１５および通信アダプタ３と接続されている。制御部１６は、赤外線受信部１１が出力した操作信号を取得して、操作信号に基づいて室内機１を制御することができる。制御部１６は、操作信号に基づいた動作モードで送風部１２を動作させ、温湿度センサ部１３が検知した温度および湿度が、設定温度および設定湿度に近づくように、送風部１２を制御する。 The control unit 16 controls the operation of the indoor unit 1. The control unit 16 is connected to the infrared receiving unit 11, the blowing unit 12, the temperature and humidity sensor unit 13, the display unit 14, the human feeling detection unit 15, and the communication adapter 3. The control unit 16 can control the indoor unit 1 based on the operation signal by acquiring the operation signal output from the infrared receiving unit 11. The control unit 16 operates the blower unit 12 in the operation mode based on the operation signal, and controls the blower unit 12 so that the temperature and the humidity detected by the temperature and humidity sensor unit 13 approach the set temperature and the set humidity.
　制御部１６は、表示部１４を用いて、冷房運転、暖房運転などの運転モード、通信モードなどを表示することもできる。図３は、図２に示す表示部１４の一例を示す図である。表示部１４は、空気調和機１００が使用することができる複数の通信モードのそれぞれに対応する発光部である。図３の例では、表示部１４は、無線ＬＡＮを示す発光部と、Ｂｌｕｅｔｏｏｔｈを示す発光部とを含む。制御部１６は、使用されている通信モードを示す発光部を発光させることによって、操作信号を受信するために現在用いている通信方式を表示することができる。 The control unit 16 can also use the display unit 14 to display an operation mode such as a cooling operation and a heating operation, a communication mode, and the like. FIG. 3 is a diagram showing an example of the display unit 14 shown in FIG. The display unit 14 is a light emitting unit corresponding to each of a plurality of communication modes which the air conditioner 100 can use. In the example of FIG. 3, the display unit 14 includes a light emitting unit indicating a wireless LAN and a light emitting unit indicating Bluetooth. The control unit 16 can display the communication method currently used to receive the operation signal by causing the light emitting unit indicating the communication mode being used to emit light.
　図２の説明に戻る。制御部１６は、１秒毎など一定の間隔で人感検知部１５の検知する検知結果を取得し、検知空間内に人が存在するか否かを監視することができる。制御部１６は、人感検知部１５の検知結果を通信アダプタ３の通信制御部３３に出力することができる。 It returns to the explanation of FIG. The control unit 16 can acquire detection results detected by the human feeling detection unit 15 at regular intervals such as every one second, and can monitor whether or not a person is present in the detection space. The control unit 16 can output the detection result of the human feeling detection unit 15 to the communication control unit 33 of the communication adapter 3.
　通信アダプタ３は、第１通信部３１と、第２通信部３２と、通信制御部３３とを有する。第１通信部３１は、第１通信方式を用いて操作信号を受信する。第２通信部３２は、第２通信方式を用いて操作信号を受信する。通信制御部３３は、人感検知部１５の検知結果に基づいて、操作信号を受信するために用いる通信方式を決定する。通信制御部３３は、操作信号を受信するために用いる通信方式に対応する通信部を有効にし、他の通信部を無効にすることで、利用可能な通信経路を変更する。無効とは、電源供給を停止するなど、消費電力を低減した状態にすることである。 The communication adapter 3 has a first communication unit 31, a second communication unit 32, and a communication control unit 33. The first communication unit 31 receives the operation signal using the first communication method. The second communication unit 32 receives the operation signal using the second communication method. The communication control unit 33 determines the communication method used to receive the operation signal based on the detection result of the human feeling detection unit 15. The communication control unit 33 changes a usable communication path by enabling a communication unit corresponding to a communication method used to receive an operation signal and disabling another communication unit. Ineffective means to reduce power consumption, such as stopping power supply.
　第１通信方式は、通信可能な範囲である通信範囲が第２通信方式よりも広い。第１通信方式は、第２通信方式よりも待機電力が大きい。人感検知部１５の検知空間は、第２通信部３２の通信範囲と重なる空間であることが望ましく、室内機１が設置された部屋の室内空間などである。ユーザ８が室内にいる場合、第１通信方式および第２通信方式の両方を用いることが可能であるが、待機電力を低減するために、第２通信方式を用いることが望ましい。また、ユーザ８が室内にいない場合、第２通信方式を用いることができない可能性が高いため、第１通信方式を用いることが望ましい。このため、通信制御部３３は、検知結果が検知空間内に人が存在することを示すとき、第１通信部３１を無効にし、第２通信部３２を有効にする。この構成を用いることで、消費電力を低減することが可能になる。 The first communication method has a communication range which is a communicable range wider than the second communication method. The first communication scheme has larger standby power than the second communication scheme. The detection space of the human feeling detection unit 15 is preferably a space overlapping with the communication range of the second communication unit 32, and is an indoor space of a room in which the indoor unit 1 is installed. When the user 8 is indoors, it is possible to use both the first communication method and the second communication method, but it is desirable to use the second communication method in order to reduce standby power. Moreover, since there is a high possibility that the second communication method can not be used when the user 8 is not indoors, it is desirable to use the first communication method. Therefore, when the detection result indicates that there is a person in the detection space, the communication control unit 33 invalidates the first communication unit 31 and enables the second communication unit 32. Power consumption can be reduced by using this configuration.
　通信制御部３３は、検知結果が検知空間内に人が存在しないことを示すとき、第２通信部３２を無効にして第１通信部３１を有効にする。第１通信方式を用いた通信経路は、通信装置４と携帯端末７とが直接接続される第１の宅内通信Ｃ３を用いた通信経路と、外部のネットワーク５を介して通信装置４と携帯端末７とが接続される宅外通信Ｃ４を用いた通信経路とを含む。ユーザ８が宅外に出て通信装置４の通信範囲から出た場合、通信装置４が携帯端末７と直接接続することができなくなる。ユーザ８が宅外に居る場合、空気調和機１００の操作即応性を求められる可能性は低い。このため、検知空間内に人が存在しないことが検知され、且つ、通信装置４が携帯端末７と直接接続することができなくなった場合、通信制御部３３は、第１通信部３１の通信頻度を下げることが望ましい。 The communication control unit 33 invalidates the second communication unit 32 and enables the first communication unit 31 when the detection result indicates that there is no person in the detection space. The communication path using the first communication method is a communication path using the first in-home communication C3 to which the communication device 4 and the portable terminal 7 are directly connected, and the communication device 4 and the portable terminal via the external network 5 And a communication path using the outside communication C4 to which the T.7 is connected. When the user 8 goes out of the home and out of the communication range of the communication device 4, the communication device 4 can not be directly connected to the portable terminal 7. When the user 8 is outside the home, the possibility of being required to respond to the operation of the air conditioner 100 is low. For this reason, when it is detected that a person does not exist in the detection space, and the communication device 4 can not be directly connected to the portable terminal 7, the communication control unit 33 determines the communication frequency of the first communication unit 31. It is desirable to lower the
　人感検知部１５の検知結果が通信経路の制御以外の目的で使用されていない場合、通信制御部３３は、検知結果が検知空間内に人が存在しないことを示すとき、人感検知部１５を停止させてもよい。この構成を用いることで、消費電力を低減することができる。通信制御部３３は、人感検知部１５を停止した後、定期的に人感検知部１５の機能を有効にし、検知空間内に人が存在するか否かを検知させることが望ましい。 When the detection result of the human feeling detection unit 15 is not used for the purpose other than control of the communication path, the communication control unit 33 detects the human feeling detection unit 15 when the detection result indicates that there is no person in the detection space. May be stopped. By using this configuration, power consumption can be reduced. It is desirable that the communication control unit 33 periodically activate the function of the human feeling detecting unit 15 after stopping the human feeling detecting unit 15, and detect whether or not a person is present in the detection space.
　上記の空気調和機１００の制御部１６および通信制御部３３は、各処理を行う電子回路である処理回路を用いて実現される。本処理回路は、専用のハードウェアであっても、メモリ及びメモリに格納されるコンピュータプログラムを実行するＣＰＵ（Central　Processing　Unit）を備える制御回路であってもよい。 The control part 16 and the communication control part 33 of said air conditioner 100 are implement | achieved using the processing circuit which is an electronic circuit which performs each process. The processing circuit may be a dedicated hardware or a control circuit including a CPU and a central processing unit (CPU) that executes a computer program stored in the memory.
　処理回路が専用のハードウェアである場合、処理回路は、例えば、ＡＳＩＣ（Application　Specific　Integrated　Circuit）、ＦＰＧＡ（Field　Programmable　Gate　Array）、またはこれらを組み合わせたものである。 When the processing circuit is dedicated hardware, the processing circuit is, for example, an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), or a combination thereof.
　図４は、図２に示す空気調和機１００の制御部１６および通信制御部３３を実現するための制御回路９０を示す図である。制御回路９０は、プロセッサ９１およびメモリ９２を有する。プロセッサ９１は、ＣＰＵであり、中央処理装置、処理装置、演算装置、マイクロコンピュータ、ＤＳＰ（Digital　Signal　Processor）などとも呼ばれる。メモリ９２は、ＲＡＭ（Random　Access　Memory）、ＲＯＭ（Read　Only　Memory）、フラッシュメモリなどの、不揮発性または揮発性の半導体メモリ、磁気ディスク、光ディスクなどである。プロセッサ９１は、メモリ９２に記憶されたコンピュータプログラムを読み出して実行することで、制御部１６および通信制御部３３の機能が実現される。また、メモリ９２は、プロセッサ９１が実行する各処理における一時メモリとしても用いられる。 FIG. 4 is a diagram showing a control circuit 90 for realizing the control unit 16 and the communication control unit 33 of the air conditioner 100 shown in FIG. The control circuit 90 includes a processor 91 and a memory 92. The processor 91 is a CPU, and is also called a central processing unit, a processing unit, an arithmetic unit, a microcomputer, a DSP (Digital Signal Processor) or the like. The memory 92 is a nonvolatile or volatile semiconductor memory such as a random access memory (RAM), a read only memory (ROM), or a flash memory, a magnetic disk, an optical disk, or the like. The processor 91 reads out and executes a computer program stored in the memory 92 to realize the functions of the control unit 16 and the communication control unit 33. The memory 92 is also used as a temporary memory in each process executed by the processor 91.
　続いて、空気調和機１００の動作について説明する。図５は、図２に示す空気調和機１００の動作例を示すフローチャートである。人感検知部１５は、検知空間内に人が存在するか否かを検知する（ステップＳ１０１）。制御部１６は、人感検知部１５の検知結果を取得して通信制御部３３に出力する。通信制御部３３は、検知結果に基づいて、検知空間内に人が存在するか否かを判断する（ステップＳ１０２）。 Subsequently, the operation of the air conditioner 100 will be described. FIG. 5 is a flowchart showing an operation example of the air conditioner 100 shown in FIG. The human feeling detection unit 15 detects whether a person is present in the detection space (step S101). The control unit 16 acquires the detection result of the human feeling detection unit 15 and outputs the detection result to the communication control unit 33. The communication control unit 33 determines whether or not a person is present in the detection space based on the detection result (step S102).
　検知空間内に人が存在する場合（ステップＳ１０２：Ｙｅｓ）、通信制御部３３は、第１通信部３１を無効にし、第２通信部３２を有効にして（ステップＳ１０３）、処理を終了する。検知空間内に人が存在しない場合（ステップＳ１０２：Ｎｏ）、通信制御部３３は、第１通信部３１を有効にし、第２通信部３２を無効にする（ステップＳ１０４）。通信制御部３３は、携帯端末７と直接接続された近距離通信が途絶したか否かを判断する（ステップＳ１０５）。近距離通信が途絶していない場合（ステップＳ１０５：Ｎｏ）、通信制御部３３は本処理を終了する。近距離通信が途絶した場合（ステップＳ１０５：Ｙｅｓ）、通信制御部３３は、第１通信部３１の通信頻度を下げる（ステップＳ１０６）。 When a person is present in the detection space (step S102: Yes), the communication control unit 33 invalidates the first communication unit 31, activates the second communication unit 32 (step S103), and ends the process. When a person does not exist in the detection space (step S102: No), the communication control unit 33 enables the first communication unit 31 and disables the second communication unit 32 (step S104). The communication control unit 33 determines whether the short distance communication directly connected to the mobile terminal 7 is interrupted (step S105). When the short distance communication is not interrupted (step S105: No), the communication control unit 33 ends the present process. When the short distance communication is interrupted (step S105: Yes), the communication control unit 33 lowers the communication frequency of the first communication unit 31 (step S106).
　図６は、図２に示す空気調和機１００の動作の変形例を示すフローチャートである。図６に示す処理のうち、図５と同様の処理については同じ符号を付することによって、ここでは説明を省略する。 FIG. 6 is a flowchart showing a modification of the operation of the air conditioner 100 shown in FIG. Among the processes shown in FIG. 6, the same processes as those in FIG. 5 are denoted by the same reference numerals, and the description thereof is omitted here.
　第１通信部３１を有効にし、第２通信部３２を無効にするステップＳ１０４の処理が行われた後、通信制御部３３は、人感検知部１５を停止させる（ステップＳ２０１）。このように人感検知部１５を停止させることによって、第１通信方式を用いた第１宅内操作または宅外操作が行われており、次に図６に示す動作が開始されるまでの間、人感検知部１５による検知動作が停止される。したがって、消費電力を低減することが可能になる。以上説明した図５または図６に示す処理は、繰り返し実行される。 After the process of step S104 for making the first communication unit 31 valid and disabling the second communication unit 32 is performed, the communication control unit 33 stops the human feeling detection unit 15 (step S201). By stopping the human feeling detection unit 15 in this manner, the first in-home operation or the out-of-home operation using the first communication method is performed, and until the operation shown in FIG. The detection operation by the human feeling detection unit 15 is stopped. Therefore, power consumption can be reduced. The process shown in FIG. 5 or 6 described above is repeatedly performed.
　なお上記の実施の形態では、通信制御部３３によって通信経路の制御が自動的に行われることとしたが、本発明はかかる例に限定されない。通信制御部３３が通信経路の制御を行うか否かは、設定画面を用いてユーザ８が切り替えることができるようにしてもよい。 In the above embodiment, the communication control unit 33 automatically controls the communication path, but the present invention is not limited to this example. Whether the communication control unit 33 performs control of the communication path may be switched by the user 8 using the setting screen.
　図７は、図２に示す通信制御部３３の機能を設定するための設定画面８１を示す図である。設定画面８１は、空気調和機１００を操作するためのアプリケーションプログラムをダウンロードした携帯端末７の表示画面上に表示される。設定画面８１は、通信制御部３３が操作信号を受信するために用いる通信経路を人感検知部１５の検知結果に基づいて制御する動作モードを有効にするか無効にするかを設定するための、通信自動切替モード設定部８２を含む。通信自動切り替えモード設定部８２が有効であることを示す「ＯＮ」に設定されている場合、通信制御部３３は、人感検知部１５の検知結果に基づいて、通信経路を制御する。通信自動切り替えモード設定部８２が無効であることを示す「ＯＦＦ」に設定されている場合、通信制御部３３は、人感検知部１５の検知結果によらず、ユーザ８によって設定される通信経路を用いて操作信号を受け付ける。 FIG. 7 is a diagram showing a setting screen 81 for setting the function of the communication control unit 33 shown in FIG. The setting screen 81 is displayed on the display screen of the portable terminal 7 which has downloaded the application program for operating the air conditioner 100. The setting screen 81 is used to set whether to enable or disable the operation mode for controlling the communication route used by the communication control unit 33 to receive the operation signal based on the detection result of the human feeling detection unit 15. And an automatic communication switching mode setting unit 82. When the communication automatic switching mode setting unit 82 is set to “ON” indicating that the communication automatic switching mode setting unit 82 is effective, the communication control unit 33 controls the communication path based on the detection result of the human feeling detection unit 15. When the communication automatic switching mode setting unit 82 is set to "OFF" indicating that the communication automatic switching mode setting unit 82 is invalid, the communication control unit 33 sets the communication route set by the user 8 regardless of the detection result of the human feeling detection unit 15. To accept the operation signal.
　設定画面８１は、宅外操作モードで動作している場合に、人感検知を停止するか否かを設定するための人感検知停止設定部８３を含む。人感検知停止設定部８３が有効であることを示す「ＯＮ」に設定されている場合、通信制御部３３は、宅外操作モードで動作しているときに人感検知部１５を停止する。人感検知停止設定部８３が無効であることを示す「ＯＦＦ」に設定されている場合、通信制御部３３は、宅外操作モードで動作しているときであっても人感検知部１５を停止しない。 The setting screen 81 includes a human-sense detection stop setting unit 83 for setting whether to stop human-sense detection when operating in the out-of-home operation mode. When the human-sense detection stop setting unit 83 is set to “ON” indicating that the user-sense-detection stop setting unit 83 is effective, the communication control unit 33 stops the human-feel detector 15 when operating in the out-of-home operation mode. When the human-sense-detection stop setting unit 83 is set to “OFF” indicating that it is invalid, the communication control unit 33 detects the human-sense detection unit 15 even when operating in the out-of-home operation mode. Do not stop.
　また設定画面８１は、宅外操作モードで動作している場合に、通信頻度の調整を行うか否かを設定するための通信頻度低減設定部８４を含む。通信頻度低減設定部８４が有効であることを示す「ＯＮ」に設定されている場合、宅外操作モードで動作しているときに、通信頻度の調整を行う。つまり、図５および図６に示すステップＳ１０５およびステップＳ１０６の動作を行う。通信頻度低減設定部８４が無効であることを示す「ＯＦＦ」に設定されている場合、宅外操作モードで動作しているときに、通信頻度の調整を行わない。つまり、図５および図６に示すステップＳ１０５およびステップＳ１０６の動作は省略される。 The setting screen 81 also includes a communication frequency reduction setting unit 84 for setting whether to adjust the communication frequency when operating in the out-of-home operation mode. When the communication frequency reduction setting unit 84 is set to “ON” indicating that the communication frequency reduction setting unit 84 is effective, the communication frequency is adjusted when operating in the out-of-home operation mode. That is, the operations of steps S105 and S106 shown in FIGS. 5 and 6 are performed. When the communication frequency reduction setting unit 84 is set to “OFF” indicating that the communication frequency reduction setting unit 84 is ineffective, the communication frequency is not adjusted when operating in the out-of-home operation mode. That is, the operations of steps S105 and S106 shown in FIGS. 5 and 6 are omitted.
　上記では、携帯端末７を用いて通信制御部３３の機能を設定する場合について説明したが、本発明はかかる例に限定されない。図７を用いて説明した設定操作は、携帯端末７にインストールされたアプリケーションに限らず、リモコン２を用いて行えるようにしてもよいし、空気調和機１００に設けられたスイッチなどの操作部を用いて行えるようにしてもよい。 Although the case where the function of the communication control unit 33 is set using the portable terminal 7 has been described above, the present invention is not limited to such an example. The setting operation described with reference to FIG. 7 may be performed using the remote controller 2 as well as the application installed in the portable terminal 7, or an operation unit such as a switch provided in the air conditioner 100 may be used. It may be possible to use it.
　以上説明したように、本実施の形態１によれば、検知空間内に人が存在するか否かを検知する人感検知部１５の検知結果に基づいて、操作信号を受信するために用いる通信経路が自動的に変更される。ユーザ８は、携帯端末７を用いて空気調和機１００を操作する際に、携帯端末７と空気調和機１００とを接続する通信経路を意識することなく自動的に、利用可能な通信経路が有効になると共に、利用不可能な通信経路と、他に使用可能な通信経路があるにも関わらず消費電力が大きくなる通信経路とが無効になる。したがって、空気調和機の利便性が向上する。 As described above, according to the first embodiment, the communication used to receive the operation signal based on the detection result of the human feeling detection unit 15 that detects whether or not a person is present in the detection space. The route is changed automatically. When the user 8 operates the air conditioner 100 using the portable terminal 7, the available communication route is automatically made effective without being aware of the communication route connecting the portable terminal 7 and the air conditioner 100. As a result, the unavailable communication path and the communication path that consumes a large amount of power in spite of other available communication paths become invalid. Therefore, the convenience of the air conditioner is improved.
　また、本実施の形態１によれば、複数の通信方式を利用可能な状態では、待機電力が小さい通信方式が有効にされる。このような構成をとることで、ユーザ８が何ら切替操作を行わなくても、自動的に消費電力を低減させることが可能になる。また上記実施の形態１によれば、複数の通信方式を利用可能な状態では、操作の即応性が高い通信方式が有効にされる。このような構成をとることで、ユーザ８が何ら切替操作を行わなくても、自動的に操作の即応性を高めることが可能になる。 Further, according to the first embodiment, in the state where a plurality of communication methods can be used, the communication method with small standby power is enabled. By adopting such a configuration, it is possible to automatically reduce power consumption without the user 8 performing any switching operation. Further, according to the first embodiment, in a state where a plurality of communication methods can be used, a communication method having high responsiveness to operation is enabled. By adopting such a configuration, it is possible to automatically improve the quick response of the operation without the user 8 performing any switching operation.
実施の形態２．
　図８は、本発明の実施の形態２にかかる空気調和機２００の機能構成を示す図である。空気調和機２００は、空気調和機１００の通信アダプタ３に搭載された第２通信部３２を備えていない。空気調和機２００のその他の機能構成は空気調和機１００と同様であるため、同じ符号を付してここでは説明を省略する。 Second Embodiment
FIG. 8 is a diagram showing a functional configuration of the air conditioner 200 according to the second embodiment of the present invention. The air conditioner 200 does not include the second communication unit 32 mounted on the communication adapter 3 of the air conditioner 100. The other functional configuration of the air conditioner 200 is the same as that of the air conditioner 100, so the same reference numerals are given and the description thereof is omitted here.
　図９は、図８に示す空気調和機２００の動作例を示すフローチャートである。ステップＳ１０１およびステップＳ１０２の動作は図５と同様であるため説明を省略する。検知空間内に人が存在する場合（ステップＳ１０２：Ｙｅｓ）、通信制御部３３は、第１通信部３１を無効にする（ステップＳ３０１）。検知空間内に人が存在しない場合（ステップＳ１０２：Ｎｏ）、通信制御部３３は、第１通信部３１を有効にする（ステップＳ３０２）。 FIG. 9 is a flow chart showing an operation example of the air conditioner 200 shown in FIG. The operations in step S101 and step S102 are the same as those in FIG. When a person is present in the detection space (step S102: Yes), the communication control unit 33 invalidates the first communication unit 31 (step S301). When a person does not exist in the detection space (step S102: No), the communication control unit 33 validates the first communication unit 31 (step S302).
　上記の動作を実行すると、検知空間内に人が存在する場合、無線ＬＡＮを用いた通信経路が無効にされるため、空気調和機２００は、リモコン２を使用して操作することが可能であり、携帯端末７を使用した操作を行うことができなくなる。検知空間内に人が存在しない場合、つまりユーザ８が空気調和機２００が設置された部屋以外の室内または宅外に居る場合、携帯端末７を使用した操作を行うことが可能になる。本実施の形態２においても実施の形態１と同様に、空気調和機２００の利便性が向上する。 When the above operation is performed, when there is a person in the detection space, the communication path using the wireless LAN is invalidated, so the air conditioner 200 can be operated using the remote control 2 , And the operation using the portable terminal 7 can not be performed. When there is no person in the detection space, that is, when the user 8 is indoors or outside the room other than the room in which the air conditioner 200 is installed, the operation using the portable terminal 7 can be performed. Also in the second embodiment, as in the first embodiment, the convenience of the air conditioner 200 is improved.
　以上の実施の形態に示した構成は、本発明の内容の一例を示すものであり、別の公知の技術と組み合わせることも可能であるし、本発明の要旨を逸脱しない範囲で、構成の一部を省略、変更することも可能である。 The configuration shown in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and one of the configurations is possible within the scope of the present invention.
