Thus, the position of the occupant can be estimated with fewer sensors than in the past. Hereinafter, embodiments of the air conditioner according to the present invention will be described.

本発明に係る第1の実施例を図1〜図25により説明する。まず、空気調和機の全体構成について図1及び図2を用いて説明する。図1は空気調和機の構成図であり、図2は空気調和機の室内機の側断面図である。   A first embodiment of the present invention will be described with reference to FIGS. First, the whole structure of an air conditioner is demonstrated using FIG.1 and FIG.2. FIG. 1 is a configuration diagram of an air conditioner, and FIG. 2 is a side sectional view of an indoor unit of the air conditioner.

空気調和機1は、室内機2と室外機6とを接続配管8で繋ぎ、室内を空気調和する。室内機2は、室内熱交換器33,室内熱交換器33の下流側に配置され室内熱交換器33の幅と略等しい長さの横流ファン方式の送風ファン311,露受皿35,フィルター231,231′,上側上下風向板291,左右風向板295等の基本的な内部構造体を備える。これらの内部構造体は、筐体ベース21に取り付けられるとともに、この筐体ベース21,化粧枠23、及び化粧枠23の前面に取り付けられた前面パネル25からなる筐体20に内包される。化粧枠23の上部には室内空気を吸い込む空気吸込口27が設けられ、化粧枠23の下部には温湿度が調整された空気を吹き出す空気吹出口29が設けられている。また、前面パネル25の下部には、運転状況を表示する表示部397と、リモコン5からの赤外線の操作信号を受ける受光部396とが配置されている。   The air conditioner 1 connects the indoor unit 2 and the outdoor unit 6 with a connection pipe 8 to air-condition the room. The indoor unit 2 is arranged on the downstream side of the indoor heat exchanger 33 and the indoor heat exchanger 33 and has a cross-flow fan type blower fan 311, a dew tray 35, a filter 231 and a length substantially equal to the width of the indoor heat exchanger 33. 231 ′, upper and lower wind direction plates 291 and left and right wind direction plates 295 are provided. These internal structures are attached to the housing base 21 and are included in the housing 20 including the housing base 21, the decorative frame 23, and the front panel 25 attached to the front surface of the decorative frame 23. An air inlet 27 for sucking room air is provided at the upper part of the decorative frame 23, and an air outlet 29 for blowing out air whose temperature and humidity are adjusted is provided at the lower part of the decorative frame 23. In addition, a display unit 397 for displaying an operation status and a light receiving unit 396 for receiving an infrared operation signal from the remote controller 5 are disposed below the front panel 25.

送風ファン311が回転すると、室内空気が空気吸込口27から室内熱交換器33及び送風ファン311を通って空気吹出口29から吹き出される。具体的には、送風ファン311からの吹き出し気流は、送風ファン311の長さに略等しい幅の吹出風路290に流れる。その後、吹出風路290途中に配置された左右風向板295により気流の左右方向が偏向されるとともに、空気吹出口29に配置された上側上下風向板291により気流の上下方向が偏向され、空気吹出口29から室内に吹き出される。   When the blower fan 311 rotates, room air is blown out from the air blowout port 29 through the indoor heat exchanger 33 and the blower fan 311 from the air suction port 27. Specifically, the blown airflow from the blower fan 311 flows through the blowout air passage 290 having a width substantially equal to the length of the blower fan 311. Thereafter, the right and left direction of the airflow is deflected by the left and right airflow direction plates 295 arranged in the middle of the blowout air passage 290, and the up and down direction of the airflow is deflected by the upper upper and lower airflow direction plates 291 arranged at the air outlet 29. The air is blown out from the outlet 29 into the room.

化粧枠23の下面に形成される空気吹出口29は、前面パネル25との分割部に隣接して配置され、吹出風路290に連通している。上側上下風向板291及び下側上下風向板292は、閉じた状態で、吹出風路290をほぼ遮蔽して室内機2の底面に連続する曲面を構成する。上側上下風向板291及び下側上下風向板292は、リモコン5からの指示に応じて、両端部に設けた回動軸を支点にして、空気調和機1の運転時に、駆動モータにより所要の角度回動して空気吹出口29を開き、その状態を保持する。空気調和機1の運転停止時には、空気吹出口29が閉じるように、上側上下風向板291及び下側上下風向板292が制御される。一方、左右風向板295は、リモコン5からの指示に応じて、下端部に設けた回動軸を支点にして駆動モータにより回動され、その状態が保持される。これにより、吹き出し空気が左右の所望の方向に吹き出される。なお、空気調和機1の運転中に上側上下風向板291,下側上下風向板292、及び左右風向板295を周期的に揺動させ、室内の広範囲に周期的に吹き出し空気を送ることもできる。   The air outlet 29 formed on the lower surface of the decorative frame 23 is disposed adjacent to the divided portion with the front panel 25 and communicates with the blowing air passage 290. The upper up / down wind direction plate 291 and the lower up / down wind direction plate 292 form a curved surface that is substantially closed by the blowout air passage 290 and is continuous with the bottom surface of the indoor unit 2 in a closed state. The upper vertical wind direction plate 291 and the lower vertical wind direction plate 292 are driven at a predetermined angle by the drive motor during operation of the air conditioner 1 with the pivot shafts provided at both ends as fulcrums according to instructions from the remote controller 5. It rotates to open the air outlet 29, and this state is maintained. When the operation of the air conditioner 1 is stopped, the upper vertical wind direction plate 291 and the lower vertical wind direction plate 292 are controlled so that the air outlet 29 is closed. On the other hand, the left and right wind direction plates 295 are rotated by a drive motor using a rotation shaft provided at the lower end as a fulcrum in accordance with an instruction from the remote controller 5, and the state is maintained. Thereby, the blown air is blown out in the left and right desired directions. During the operation of the air conditioner 1, the upper vertical wind direction plate 291, the lower vertical wind direction plate 292, and the left and right wind direction plate 295 can be periodically oscillated so that the blown air can be sent periodically over a wide range in the room. .

可動パネル251は、下部に設けた回動軸を支点として駆動モータにより回動され、空気調和機1の運転時に、前側空気吸込み部230′を開くように構成される。これにより、運転時に、前側空気吸込み部230′からも、室内空気が室内機2内に吸引される。空気調和機1の停止時には、前側空気吸込み部230′を閉じるように制御される。   The movable panel 251 is rotated by a drive motor with a rotation shaft provided at a lower portion as a fulcrum, and is configured to open the front air suction portion 230 ′ when the air conditioner 1 is operated. As a result, during operation, room air is also sucked into the indoor unit 2 from the front air suction portion 230 ′. When the air conditioner 1 is stopped, the front air suction part 230 'is controlled to be closed.

室内機2は、内部の電装品ボックスに制御基板を備え、この制御基板にマイコンが設けられる。このマイコンは、室内温度センサ,室内湿度センサ等の各種のセンサからの信号を受信するとともに、受光部396を介してリモコン5からの操作信号を受信する。このマイコンは、これらの信号に基づいて、室内送風ファン311,可動パネル駆動モータ,上下風向板駆動モータ,左右風向板駆動モータ等を制御すると共に、室外機6との通信を司り、室内機2を統括して制御する。   The indoor unit 2 includes a control board in an internal electrical component box, and a microcomputer is provided on the control board. The microcomputer receives signals from various sensors such as an indoor temperature sensor and an indoor humidity sensor, and also receives an operation signal from the remote controller 5 via the light receiving unit 396. Based on these signals, the microcomputer controls the indoor blower fan 311, the movable panel drive motor, the up / down wind direction plate drive motor, the left / right wind direction plate drive motor, and the like, and controls communication with the outdoor unit 6. To control.

フィルター231,231′は、吸い込まれた室内空気中に含まれる塵埃を取り除くものであり、室内熱交換器33の吸込側を覆うように配置されている。露受皿35は、室内熱交換器33の前後両側の下端部下方に配置され、冷房運転時や除湿運転時に室内熱交換器33に発生する凝縮水を受ける。露受皿35に集められた凝縮水は、ドレン配管37を通して室外に排出される。   The filters 231 and 231 ′ remove dust contained in the sucked room air, and are arranged so as to cover the suction side of the indoor heat exchanger 33. The dew tray 35 is disposed below the lower ends of the front and rear sides of the indoor heat exchanger 33 and receives condensed water generated in the indoor heat exchanger 33 during the cooling operation and the dehumidifying operation. The condensed water collected in the dew tray 35 is discharged outside through the drain pipe 37.

次に、上下風向板について図3及び図4を用いて説明する。図3は室内機の冷房・除湿運転時の側断面図である。図4は室内機の暖房運転時の側断面図である。上下風向板は前述のように上側上下風向板291及び下側上下風向板292から構成される。本明細書では主に上側上下風向板291について述べるので、単に上下風向板と記した場合は上側上下風向板を表し、下側上下風向板と記した場合は下側上下風向板を表す。上側上下風向板291は空気吹出口29に設けられ、上下風向板駆動モータ(図示せず)により、吹き出し空気を下吹出し、または水平吹出しなどに偏向する。   Next, an up-and-down wind direction board is demonstrated using FIG.3 and FIG.4. FIG. 3 is a side sectional view of the indoor unit during the cooling / dehumidifying operation. FIG. 4 is a side sectional view of the indoor unit during heating operation. As described above, the vertical wind direction plate is composed of the upper vertical wind direction plate 291 and the lower vertical wind direction plate 292. In this specification, the upper vertical wind direction plate 291 is mainly described. Therefore, the upper vertical wind direction plate is simply referred to as the upper vertical wind direction plate, and the lower vertical wind direction plate is referred to as the lower vertical wind direction plate. The upper vertical wind direction plate 291 is provided at the air outlet 29 and deflects the blown air downward or horizontal by a vertical wind direction drive motor (not shown).

図2に示すように、運転停止時は、制御装置により、上側上下風向板291,下側上下風向板292,可動パネル251が、空気吹出口29を閉じるように制御される。これにより、上側上下風向板291は、吹出風路290の上方拡大部290eの前方に回動して収納され、吹出風路上方拡大部290eを遮蔽し、下側上下風向板292と協働して空気吹出口29を閉じる。吹出風路上方拡大部290eのほぼ中央に、後述する赤外線検知装置410が設けられる。運転停止時には、上側上下風向板291は空気調和機の前面と底面の交差部に配置され、滑らで曲率の大きい曲面である外側風向面291aが空気調和機の外形に合致するように位置する。これにより、上側上下風向板291及び下側上下風向板292は外面となる風向面により、空気調和機の前面から底面にかけての外形を連続的に形成する。このため、運転停止時には、赤外線検知装置410は上側上下風向板291により遮蔽され、空気調和機の外観は不必要な凹凸の無い柔らかな落ち着いた形状となり、室内の雰囲気を乱すことがない。   As shown in FIG. 2, when the operation is stopped, the control device controls the upper vertical wind direction plate 291, the lower vertical wind direction plate 292, and the movable panel 251 so as to close the air outlet 29. As a result, the upper vertical wind direction plate 291 is rotated and stored in front of the upper enlarged portion 290e of the blowout air passage 290, shields the blowout air passage upper enlarged portion 290e, and cooperates with the lower vertical wind direction plate 292. Close the air outlet 29. An infrared detection device 410, which will be described later, is provided at substantially the center of the blowout air passage upper enlarged portion 290e. When the operation is stopped, the upper vertical wind direction plate 291 is disposed at the intersection of the front surface and the bottom surface of the air conditioner, and the outer wind direction surface 291a, which is a smooth curved surface with a large curvature, is positioned so as to match the outer shape of the air conditioner. Thus, the upper vertical wind direction plate 291 and the lower vertical wind direction plate 292 continuously form an outer shape from the front surface to the bottom surface of the air conditioner by the wind direction surface serving as the outer surface. For this reason, when the operation is stopped, the infrared detection device 410 is shielded by the upper vertical wind direction plate 291, and the appearance of the air conditioner has a soft and calm shape without unnecessary unevenness and does not disturb the indoor atmosphere.

図3に示すように、空気調和機を冷房運転する際には、上側上下風向板291及び下側上下風向板292は、吹出風路290の上壁290a,下壁290bと略平行な姿勢または水平な向きにして使用される。これにより、吹き出された冷風が直接、在室者に当って不快感を生じさせないように、適宜、上下風向板の方向が調整され、在室者の周囲を快適な温湿度に保つ。   As shown in FIG. 3, when the air conditioner is in a cooling operation, the upper vertical wind direction plate 291 and the lower vertical wind direction plate 292 are in a posture substantially parallel to the upper wall 290a and the lower wall 290b of the blowout air passage 290 or Used in a horizontal orientation. Thus, the direction of the up-and-down air direction plate is adjusted as appropriate so that the blown cold air does not directly hit the occupant and cause discomfort, and the occupant is kept at a comfortable temperature and humidity.

極弱い冷房または暖房運転を行う際には、後述する図17に示すように、上側上下風向板291をやや上向きにし、下側上下風向板292をほぼ閉じる姿勢にして、吹出風路290の下流に設けた上方に拡大する吹出風路上方拡大部290eに吹き出し気流を流す。これにより、吹き出し空気の一部が極弱い風となって吹出風路上方拡大部290eを通って室内に拡散し、微弱な冷房または暖房が行われる。   When performing extremely weak cooling or heating operation, as shown in FIG. 17 to be described later, the upper vertical wind direction plate 291 is slightly upward and the lower vertical wind direction plate 292 is substantially closed, and downstream of the blowout air passage 290. The blown airflow is caused to flow through the blowout air passage upper enlarged portion 290e that is provided on the upper side. As a result, a part of the blown air becomes extremely weak wind and diffuses into the room through the blown air path upper enlarged portion 290e, and weak cooling or heating is performed.

更に、吹出風路上方拡大部290eを利用して、吹き出した風をすぐさま、空気吸込口27から吸い込ませるショートサーキット運転を行うことで、室内熱交換器の乾燥運転や空気調和機内部の脱臭運転などの空気調和機のメンテナンス動作を行わせることもできる。   Furthermore, by using the blowout air channel upper enlarged portion 290e, the short circuit operation in which the blown wind is immediately sucked from the air suction port 27 is performed, so that the drying operation of the indoor heat exchanger and the deodorization operation inside the air conditioner are performed. The maintenance operation of the air conditioner such as can be performed.

図4に示すように、空気調和機を暖房運転する際には、上側上下風向板291,292をほぼ垂直に近い姿勢にする。これにより、吹出風路290を流れる温風は空気調和機から下方に向かって吹き出し、床面近くまで到達して、足もと近くを暖め、室内を快適な環境にする。   As shown in FIG. 4, when the air conditioner is in a heating operation, the upper vertical wind direction plates 291 and 292 are placed in a substantially vertical posture. Thereby, the warm air flowing through the blowout air passage 290 blows downward from the air conditioner, reaches near the floor, warms the feet, and makes the room a comfortable environment.

次に、本実施例の空気調和機が備える静電霧化装置について図2,図5及び図6を用いて説明する。図5は静電霧化装置の霧化ユニットの吹出風路への取付部斜視図である。図6は静電霧化装置の水生成部を正面から見た部分断面図である。静電霧化装置は、鋭利な形状を持つ電極の先端に液体を供給し、この液体に高電圧を印加して電極の先端から帯電した液体の微細粒を放出させ、脱臭,殺菌等の効果を得るものである。本実施例の空気調和機は静電霧化装置と人検知装置と組合わせ、人検知装置により在室者の存在が推定されるエリアに、静電霧化方式により帯電した微細粒の水を放出し、在室者の周囲環境を向上させるものである。   Next, the electrostatic atomizer with which the air conditioner of a present Example is provided is demonstrated using FIG.2, FIG.5 and FIG.6. FIG. 5 is a perspective view of the attachment portion of the atomizing unit of the electrostatic atomizer to the blowing air passage. FIG. 6 is a partial cross-sectional view of the water generation unit of the electrostatic atomizer when viewed from the front. An electrostatic atomizer supplies liquid to the tip of an electrode having a sharp shape, and applies a high voltage to the liquid to discharge fine particles of the charged liquid from the tip of the electrode, resulting in effects such as deodorization and sterilization. Is what you get. The air conditioner of the present embodiment is combined with an electrostatic atomizer and a human detection device, and fine particles of water charged by an electrostatic atomization method are applied to an area where the presence of a person in the room is estimated by the human detection device. It releases and improves the surrounding environment of the occupants.

静電霧化装置42は、高電圧発生装置と、高電圧発生装置の高電圧端子から伸びる導電体429と、導電体429に霧化接続部424で吸水時に電気的に接触する霧化電極422及びイオン電極428と、霧化電極422に供給する水の水生成部440等を備える。高電圧発生装置で発生させた−3kV〜−6kVの高電圧を霧化電極422及びイオン電極428に印加し、霧化電極422に水生成部440から水分を供給することで、霧化電極422先端から帯電した微細粒の水を放出させ、また、イオン電極428からイオンを放出させる。静電霧化装置42は帯電した微細粒の水及びイオンの放出部430を室内機2の吹出風路290に臨むように吹出風路側壁290cから突出させ、帯電した微細粒の水を吹出風路に流れる吹き出し空気の中に放出する。その後、帯電した微細粒の水は吹き出し気流に乗り、上側上下風向板291,下側上下風向板292、及び左右風向板295で室内の所要の方向に風向が調整されて室内機2から吹き出される。   The electrostatic atomizer 42 includes a high-voltage generator, a conductor 429 extending from a high-voltage terminal of the high-voltage generator, and an atomization electrode 422 that contacts the conductor 429 at the time of water absorption at the atomization connection 424. And an ion electrode 428, a water generation unit 440 for supplying water to the atomizing electrode 422, and the like. A high voltage of −3 kV to −6 kV generated by the high voltage generator is applied to the atomizing electrode 422 and the ion electrode 428, and water is supplied to the atomizing electrode 422 from the water generating unit 440, whereby the atomizing electrode 422 is supplied. Fine charged water is discharged from the tip, and ions are released from the ion electrode 428. The electrostatic atomizer 42 protrudes the charged fine-grained water and ion discharge part 430 from the blowout air channel side wall 290c so as to face the blowout air channel 290 of the indoor unit 2, and the charged fine-grained water is blown out from the blowout air. It discharges into the blown air flowing in the road. Thereafter, the charged fine-grained water rides on the blowout airflow, and is blown out of the indoor unit 2 with the wind direction adjusted to the required direction in the room by the upper vertical wind direction plate 291, the lower vertical wind direction plate 292, and the left and right wind direction plate 295. The

水生成部440は、ペルチェ効果を利用して空気から水分を凝縮させる。ペルチェ素子441の低温部442に周囲の空気中の水分を凝縮させる冷却板425を、高温部444に周囲の空気で冷却される放熱板338を備える。冷却板425はペルチェ素子441の低温部442に電気絶縁シート443を挟んで密着させ、周囲の空気中の水分を凝縮させる。冷却板425に結露した水は次第に大きくなり、垂直に立てた冷却板425上を流下し、下端の屈曲部425aでペルチェ素子441の低温部442を離れ、下方に設けた保水部材423に向けて落下する。落下した水滴は保水部材423により保持される。保水部材423は毛管現象で結露した水が移動できるように多孔質や繊維質の素材で構成され、保水部材423の適所に霧化電極422の導水部422bが挿入され、保水部材423に保持された水分が毛管現象で導水部422bを通して霧化部422aに供給される。   The water production | generation part 440 condenses a water | moisture content from air using a Peltier effect. A cooling plate 425 that condenses the moisture in the surrounding air is provided in the low temperature part 442 of the Peltier element 441, and a heat dissipation plate 338 that is cooled by the surrounding air is provided in the high temperature part 444. The cooling plate 425 is brought into close contact with the low temperature part 442 of the Peltier element 441 with the electric insulating sheet 443 interposed therebetween, and condenses moisture in the surrounding air. The water condensed on the cooling plate 425 gradually increases, flows down on the vertically standing cooling plate 425, leaves the low temperature portion 442 of the Peltier element 441 at the lower bent portion 425 a, and toward the water retaining member 423 provided below. Fall. The dropped water droplet is held by the water retention member 423. The water retaining member 423 is made of a porous or fibrous material so that water condensed due to capillary action can move, and the water guiding portion 422b of the atomizing electrode 422 is inserted into an appropriate position of the water retaining member 423, and is held by the water retaining member 423. Moisture is supplied to the atomizing section 422a through the water guiding section 422b by capillary action.

送風ファン311を駆動し、静電霧化装置42を運転して、高電圧発生装置450からの負の高電圧を霧化電極422及びイオン電極428に印加する。このとき、イオン電極428から周辺の大気に向けてコロナ放電が起こり、電子が放出され、イオンが発生する。また、霧化電極422からは帯電した微細粒の水が放出され、このイオン及び帯電した微細粒の水は吹出風路290から吹き出し気流に乗って室内に吹き出される。なお、静電霧化装置の放出部は吹出風路側壁から突出するものに限定されるものではない。吹出風路の上壁や吹出風路の下壁から突出するものや吹出風路に設置されるものであっても同様の効果を奏することができる。   The blower fan 311 is driven, the electrostatic atomizer 42 is operated, and a negative high voltage from the high voltage generator 450 is applied to the atomization electrode 422 and the ion electrode 428. At this time, corona discharge occurs from the ion electrode 428 toward the surrounding atmosphere, electrons are emitted, and ions are generated. The atomized electrode 422 discharges charged fine-grained water, and the ions and the charged fine-grained water are blown out from the blowout air passage 290 into the room in a blowing airflow. In addition, the discharge | release part of an electrostatic atomizer is not limited to what protrudes from a blowing wind path side wall. The same effect can be achieved even if the projection protrudes from the upper wall of the blowout air passage, the lower wall of the blowout air passage, or is installed in the blowout air passage.

次に、本実施例の空気調和機が備える赤外線センサについて図7〜図12を用いて説明する。図7は室内機の外観斜視図である。図8は室内機の上下風向板を開いた外観斜視図である。図9は室内機の赤外線センサの水平配置図である。図10は赤外線センサの検知領域区分図である。図11は赤外線センサの構成図である。図12は赤外線センサの他の構成例である。   Next, the infrared sensor with which the air conditioner of a present Example is provided is demonstrated using FIGS. FIG. 7 is an external perspective view of the indoor unit. FIG. 8 is an external perspective view of the indoor unit with the up and down wind direction plate opened. FIG. 9 is a horizontal layout of the infrared sensor of the indoor unit. FIG. 10 is a detection area division diagram of the infrared sensor. FIG. 11 is a configuration diagram of the infrared sensor. FIG. 12 shows another configuration example of the infrared sensor.

図8に示すように、本実施例では、赤外線検知装置410を空気吹出口から室内を臨むように配置する。具体的には、吹出風路上方拡大部290eの長手方向の中央部に設けられ、運転停止時には図7のように上側上下風向板291で室内から遮蔽され、室内に違和感を与えないようにされている。   As shown in FIG. 8, in this embodiment, the infrared detecting device 410 is arranged so as to face the room from the air outlet. Specifically, it is provided at the central portion in the longitudinal direction of the blowout air passage upper enlarged portion 290e, and is shielded from the room by the upper vertical airflow direction plate 291 as shown in FIG. 7 when the operation is stopped, so that the room does not feel strange. ing.

図9に示すように、赤外線検知装置410は、一例として、3個の赤外線センサ410a,b,cを台座415を介して、基板416に搭載する。各赤外線センサ410a,b,cは台座415により検知する方向が異なるため、より広角な検知範囲が構成される。さらに各赤外線センサ410a,b,cを俯角をもって実装することにより、室内床面の大半を視野に収めることができる。尚、本実施例においては、複数の赤外線センサの左右方向の光軸が同一方向とならないように配置する。これにより、左右方向に展開して配置した複数の赤外線センサにより、室内を左右方向に複数に区分できる。   As shown in FIG. 9, as an example, the infrared detection device 410 has three infrared sensors 410 a, b, and c mounted on a substrate 416 via a pedestal 415. Since each infrared sensor 410a, b, c has a different detection direction depending on the pedestal 415, a wider detection range is formed. Furthermore, by mounting each infrared sensor 410a, b, c with a depression angle, most of the indoor floor surface can be accommodated in the field of view. In this embodiment, the plurality of infrared sensors are arranged so that the left and right optical axes are not in the same direction. Thus, the room can be divided into a plurality of left and right directions by a plurality of infrared sensors deployed in the left and right direction.

図10に示す検知領域区分図は、空調空間を上方から見た図であり、室902内に室内機2が設置されている。室内は赤外線センサ410a,b,cが検知する検知エリア610A,B,C、赤外線センサ410a,bが重複して検知する検知エリア610AB,赤外線センサ410b,cが重複して検知する検知エリア610BCに区分される。赤外線センサ410aのみが検知した場合は、検知エリア610Aに人体が存在すると推定する。赤外線センサ410bのみが検知した場合は、検知エリア610Bに人体が存在すると推定する。赤外線センサ410cのみが検知した場合は、検知エリア610Cに人体が存在すると推定する。赤外線センサ410aと赤外線センサ410bの両方が検知した場合は、検知エリア610ABに人体が存在すると推定する。赤外線センサ410bと赤外線センサ410cの両方が検知した場合は、検知エリア610BCに人体が存在すると推定する。   The detection area division diagram shown in FIG. 10 is a view of the air-conditioned space as viewed from above, and the indoor unit 2 is installed in the room 902. Indoors are detection areas 610A, B, C detected by infrared sensors 410a, b, c, detection areas 610AB detected by overlapping infrared sensors 410a, b, and detection areas 610BC detected by overlapping infrared sensors 410b, c. It is divided. When only the infrared sensor 410a detects, it estimates that a human body exists in the detection area 610A. When only the infrared sensor 410b detects, it is estimated that a human body exists in the detection area 610B. When only the infrared sensor 410c detects, it is estimated that a human body exists in the detection area 610C. When both the infrared sensor 410a and the infrared sensor 410b detect, it is estimated that a human body exists in the detection area 610AB. When both the infrared sensor 410b and the infrared sensor 410c detect, it is estimated that a human body exists in the detection area 610BC.

本実施例では赤外線センサ410a,b,cとして、焦電型の赤外線センサを用いる。図11に示す赤外線検知装置410は、焦電型の赤外線センサ410a,b,c、焦電型の赤外線センサ410a,b,cの出力を増幅する増幅器130,出力をデジタル信号へと変換するコンパレータ131,出力を読み込み演算処理を行うマイコン132を備える。この構成によれば、マイコン132は複数の赤外線センサからの信号を同時に受けて、その組合わせからどのエリアに人が存在するかを信号を受けた時点で判断できるので、室内状況の変化を正確に捉えることができる。この場合、焦電型赤外線センサを複数個備えると、それに伴い同数の増幅器130とコンパレータ131,マイコン132の読み込みポートが必要となる。   In this embodiment, pyroelectric infrared sensors are used as the infrared sensors 410a, b, and c. 11 includes a pyroelectric infrared sensor 410a, b, c, an amplifier 130 that amplifies the output of the pyroelectric infrared sensor 410a, b, c, and a comparator that converts the output into a digital signal. 131, a microcomputer 132 that reads the output and performs arithmetic processing. According to this configuration, since the microcomputer 132 can simultaneously receive signals from a plurality of infrared sensors and determine in which area a person exists from the combination, it can accurately detect changes in room conditions. Can be caught. In this case, when a plurality of pyroelectric infrared sensors are provided, the same number of amplifiers 130, comparators 131, and reading ports of the microcomputer 132 are required.

また、他の構成例として、図12に示すような構成としてもよい。図12に示す赤外線検知装置410は、切換装置133を用い、増幅器130と、コンパレータ131とを、切換装置133の後段に備える。これにより、切換装置133により出力を一系統に集約できるため、増幅器130,コンパレータ131、及びマイコン132の読み込みポートを少なくすることができ、その結果、部品点数を削減し、回路規模を縮小することができる。この場合、マイコン132は複数の赤外線センサからの信号を順次受け、全部の信号を受けた後に、その組合わせからどのエリアに人が存在するかを判断するので、信号を順次受けている間の室内状況の変化には対応できない場合がある。検知エリアの区分の細かさや、人の動きの早さ、空気調和機の制御目的などにより、回路を選択することができる。   Further, as another configuration example, a configuration as shown in FIG. 12 may be used. An infrared detection device 410 shown in FIG. 12 uses a switching device 133 and includes an amplifier 130 and a comparator 131 at the subsequent stage of the switching device 133. As a result, since the output can be consolidated into one system by the switching device 133, the reading ports of the amplifier 130, the comparator 131, and the microcomputer 132 can be reduced. As a result, the number of parts can be reduced and the circuit scale can be reduced. Can do. In this case, the microcomputer 132 sequentially receives signals from a plurality of infrared sensors, and after receiving all the signals, the microcomputer 132 determines in which area a person exists from the combination. May not be able to respond to changes in room conditions. The circuit can be selected according to the fineness of the detection area classification, the speed of human movement, the control purpose of the air conditioner, and the like.

上記のように、赤外線検知装置410を構成すれば、焦電型赤外線センサ410a,b,cから環境や人体の存在,人体の活動に伴ったアナログ信号が出力され、増幅器130にて増幅し、コンパレータ131により、微小な信号やノイズを除去し、またデジタル信号に変換し、マイコン132の読み込みポートに入力され、マイコン132で演算処理される。その結果により、人体が存在すると判断したエリアに対し、上側上下風向板291,292,左右風向板295が向けられ、送風ファン311によって、調和された空気が送風される。   As described above, if the infrared detecting device 410 is configured, analog signals are output from the pyroelectric infrared sensors 410a, 410b, 410c, the presence of the environment, the presence of the human body, and the human activity, and are amplified by the amplifier 130. A minute signal and noise are removed by the comparator 131, converted into a digital signal, input to the reading port of the microcomputer 132, and processed by the microcomputer 132. As a result, the upper and lower wind direction plates 291 and 292 and the left and right wind direction plates 295 are directed toward the area where the human body is determined to exist, and the conditioned air is blown by the blower fan 311.

次に、赤外線センサからの信号により、存在エリアを推定する方法について図13〜図15を用いて説明する。図13〜図15は赤外線センサの検知推定方法説明図である。図13は検知エリア610Aから検知エリア610Bに人が移動した場合に、赤外線検知装置410からの信号に応じて人の存在エリアを推定する方法を示している。赤外線検知装置410からの信号は、マイコン132に入力される信号であり、環境や人体の存在,人体の活動に伴ったデジタル信号である。赤外線センサ410aからの出力があり、赤外線センサ410bからの出力が無ければ、検知エリア610Aに人体が存在すると推定する。次に、赤外線センサ410aからの出力があり、赤外線センサ410bからの出力があれば、検知エリア610ABに人体が移動したことが分かる。赤外線センサ410aからの出力が無く、赤外線センサ410bからの出力があれば検知エリア610Bに人体が移動したことがわかる。ある単位時間あたりの中で数回のみ検知され、次に隣の検知エリアでまた数回検知されるような場合、人体が一時的に通過したと推定する。   Next, a method for estimating an existing area based on a signal from an infrared sensor will be described with reference to FIGS. FIGS. 13 to 15 are explanatory diagrams of detection estimation methods of the infrared sensor. FIG. 13 shows a method of estimating the presence area of a person according to a signal from the infrared detection device 410 when a person moves from the detection area 610A to the detection area 610B. A signal from the infrared detection device 410 is a signal input to the microcomputer 132, and is a digital signal associated with the environment, the presence of the human body, and the activity of the human body. If there is an output from the infrared sensor 410a and no output from the infrared sensor 410b, it is estimated that a human body exists in the detection area 610A. Next, if there is an output from the infrared sensor 410a and an output from the infrared sensor 410b, it can be understood that the human body has moved to the detection area 610AB. If there is no output from the infrared sensor 410a and there is an output from the infrared sensor 410b, it is understood that the human body has moved to the detection area 610B. If the detection is made only several times within a certain unit time and then detected several times in the next detection area, it is estimated that the human body has temporarily passed.

また、図14は検知エリア610B内で人が動いている場合に、赤外線検知装置410からの信号に応じて人の存在エリアを推定する方法を示している。赤外線センサ410bからの出力があり、赤外線センサ410a,cからの出力が無ければ、検知エリア610Bに人体が存在すると推定する。次のサンプリングにおいても赤外線センサ410bからの出力があり、赤外線センサ410a,cからの出力がないことが継続していれば、人体が検知エリア410Bに存在し続けていることがわかる。サンプリング毎に赤外線センサ410bからの出力があれば、人が継続的に活動していると判断する。   FIG. 14 shows a method for estimating the presence area of a person according to a signal from the infrared detection device 410 when a person is moving in the detection area 610B. If there is an output from the infrared sensor 410b and no output from the infrared sensors 410a, c, it is estimated that a human body is present in the detection area 610B. If there is an output from the infrared sensor 410b in the next sampling and no output from the infrared sensors 410a and c continues, it can be understood that the human body continues to exist in the detection area 410B. If there is an output from the infrared sensor 410b for each sampling, it is determined that the person is continuously active.

図15は検知エリア610Bから検知エリア610BCに人が移動した場合に、赤外線検知装置410からの信号に応じて人の存在エリアを推定する方法を示している。赤外線センサ410bからの出力があり、赤外線センサ410aからの出力が無ければ、検知エリア610Bに人体が存在すると推定する。次に、赤外線センサ410b,cからの出力があり、赤外線センサ410aからの出力が無ければ、検知エリア610BCに人体が移動したことがわかる。赤外線センサ410a,b,cからの出力が無ければ、人体はどの検知エリアにも移動していないことがわかるため、検知エリア610BCに引続き存在していることがわかる。また、その後も赤外線センサ410a,b,cからの出力が無ければ、人体は検知エリア610BCで静止中であると判断する。以上のように、パルスの回数や周期から人体の位置や活動状態を推定することができるため、無駄が無く、効率の良い空調を使用者に提供することができる。   FIG. 15 shows a method for estimating the presence area of a person according to a signal from the infrared detection device 410 when a person moves from the detection area 610B to the detection area 610BC. If there is an output from the infrared sensor 410b and no output from the infrared sensor 410a, it is estimated that a human body exists in the detection area 610B. Next, if there is an output from the infrared sensors 410b, c and no output from the infrared sensor 410a, it is known that the human body has moved to the detection area 610BC. If there is no output from the infrared sensors 410a, b, and c, it can be seen that the human body has not moved to any detection area, and therefore it can be seen that the human body continues to exist in the detection area 610BC. If there is no output from the infrared sensors 410a, b, c thereafter, it is determined that the human body is stationary in the detection area 610BC. As described above, since the position and activity state of the human body can be estimated from the number and period of pulses, there is no waste and efficient air conditioning can be provided to the user.

次に、上下風向板による垂直方向の室内領域の区分について図16〜図20を用いて説明する。図16(a)は室内機の上下風向板による検知領域説明図、図16(b)は上下風向板部拡大断面図である。図17(a)は上下風向板による遠方領域検知説明図、図17(b)は上下風向板部拡大断面図である。図18(a)は上下風向板による遠方〜中間領域検知説明図、図18(b)は上下風向板部拡大断面図である。図19(a)は上下風向板による遠方〜近接領域検知説明図、図19(b)は上下風向板部拡大断面図である。図20(a)は上下風向板による遠方〜直下領域検知説明図、図20(b)は上下風向板部拡大断面図である。   Next, the division of the indoor region in the vertical direction by the up and down wind direction plates will be described with reference to FIGS. FIG. 16A is an explanatory view of a detection area by an up-and-down air direction plate of the indoor unit, and FIG. 16B is an enlarged cross-sectional view of the up-and-down air direction plate portion. FIG. 17A is an explanatory diagram for detecting a distant area by the vertical wind direction plate, and FIG. 17B is an enlarged sectional view of the vertical direction plate portion. FIG. 18A is an explanatory diagram for detecting the far-to-intermediate region by the vertical wind direction plate, and FIG. 18B is an enlarged sectional view of the vertical wind direction plate portion. FIG. 19A is an explanatory diagram for detecting a far-to-close region by the vertical wind direction plate, and FIG. 19B is an enlarged sectional view of the vertical wind direction plate portion. FIG. 20A is an explanatory diagram of detection of a far-to-below region by the vertical wind direction plate, and FIG. 20B is an enlarged sectional view of the vertical wind direction plate portion.

本発明では、左右方向の検知エリアの区分に加えて、奥行き方向についても上下風向板を用いて検知エリアを区分する。前述のように、上側上下風向板291は、吹出風路290の下流に設けた上方に拡大する吹出風路上方拡大部290eに吹き出し気流を導く。在室者の有無を検知するときに、上側上下風向板291を図16に示すように、赤外線検知装置410の視野を部分的に遮るような位置に回動させる。上側上下風向板291を停止させる位置は図16(b)の拡大図に示すように、上側上下風向板291の図象の先端に付けた符号i,j,k,m,nの位置とする(以下、これらの位置をそれぞれ「上側上下風向板位置491i,j,k,m,n」という。)。ここで、上側上下風向板位置491iでは赤外線検知装置410の全視野が上側上下風向板291に隠され、在室者の有無を検知することはできない。上側上下風向板位置491jでは赤外線検知装置410の視野のうち、検知範囲591jのみが検知可能である。上側上下風向板位置491kでは検知範囲591kのみが検知可能である。上側上下風向板位置491mでは検知範囲591mのみが検知可能である。上側上下風向板位置491nでは検知範囲591n=全視野が検知可能である。   In the present invention, in addition to the detection area classification in the left-right direction, the detection area is also divided in the depth direction using the vertical wind direction plate. As described above, the upper vertical airflow direction plate 291 guides the blown airflow to the blowing air channel upper enlarged portion 290e that is provided on the downstream side of the blowing air channel 290 and expands upward. When detecting the presence or absence of an occupant, the upper vertical wind direction plate 291 is rotated to a position that partially blocks the field of view of the infrared detecting device 410 as shown in FIG. As shown in the enlarged view of FIG. 16 (b), the position at which the upper vertical wind direction plate 291 is stopped is the position of symbols i, j, k, m, and n attached to the tip of the upper vertical wind direction plate 291. (Hereinafter, these positions are referred to as “upper vertical wind direction plate positions 491i, j, k, m, n”, respectively). Here, at the upper vertical wind direction plate position 491i, the entire field of view of the infrared detecting device 410 is hidden by the upper vertical wind direction plate 291 and it is impossible to detect the presence or absence of a room occupant. Only the detection range 591j in the visual field of the infrared ray detection device 410 can be detected at the upper vertical wind direction plate position 491j. Only the detection range 591k can be detected at the upper vertical wind direction plate position 491k. Only the detection range 591m can be detected at the upper vertical wind direction plate position 491m. At the upper vertical wind direction plate position 491n, the detection range 591n = the entire visual field can be detected.

上側上下風向板291を使用して在室者の位置を検知する場合は、まず、図17のように上側上下風向板291を上側上下風向板位置491jで停止させ、赤外線検知装置410で在室者の有無を検知する。このとき在室者が検知されると、在室者は検知範囲591jに存在することがわかる。   When detecting the position of a room occupant using the upper vertical wind direction plate 291, first, the upper vertical wind direction plate 291 is stopped at the upper vertical wind direction plate position 491 j as shown in FIG. The presence or absence of a person is detected. If an occupant is detected at this time, it is understood that the occupant exists in the detection range 591j.

次に、図18のように上側上下風向板291を上側上下風向板位置491kで停止させ、赤外線検知装置410で在室者の有無を検知する。このとき在室者が検知されると、在室者は検知範囲591jを含む検知範囲591kに存在することがわかる。   Next, as shown in FIG. 18, the upper vertical wind direction plate 291 is stopped at the upper vertical wind direction plate position 491k, and the presence or absence of a person in the room is detected by the infrared detection device 410. When a room occupant is detected at this time, it is understood that the room occupant exists in the detection range 591k including the detection range 591j.

次に、図19のように上側上下風向板291を上側上下風向板位置491mで停止させ、赤外線検知装置410で在室者の有無を検知する。このとき在室者が検知されると、在室者は検知範囲591kを含む検知範囲591mに存在することがわかる。   Next, as shown in FIG. 19, the upper vertical wind direction plate 291 is stopped at the upper vertical wind direction plate position 491m, and the presence or absence of a person in the room is detected by the infrared detection device 410. If the occupant is detected at this time, it is understood that the occupant is present in the detection range 591m including the detection range 591k.

次に、図20のように上側上下風向板291を上側上下風向板位置491nで停止させ、赤外線検知装置410で在室者の有無を検知する。このとき在室者が検知されると、在室者は検知範囲591mを含む検知範囲591nに存在することがわかる。   Next, as shown in FIG. 20, the upper vertical wind direction plate 291 is stopped at the upper vertical wind direction plate position 491n, and the presence or absence of a person in the room is detected by the infrared detection device 410. If the occupant is detected at this time, the occupant is present in the detection range 591n including the detection range 591m.

赤外線検知装置で検知した在室者の有無から、奥行き方向の存在エリアを推定する方法について図21〜図25を用いて説明する。図21は上下風向板による垂直方向の検知領域区分図である。図22は上下風向板による床面の検知領域区分図である。図23は存在エリアと赤外線センサの検知反応を示す表である。図24は赤外線センサの検知反応パターンと存在エリアの推定表である。図25は赤外線センサと上下風向板による床面の検知領域区分図である。   A method for estimating the presence area in the depth direction from the presence or absence of a room occupant detected by the infrared detection device will be described with reference to FIGS. FIG. 21 is a vertical sectional view of the detection area by the vertical wind direction plate. FIG. 22 is a detection area division diagram of the floor surface by the vertical wind direction plate. FIG. 23 is a table showing the presence area and the detection response of the infrared sensor. FIG. 24 is an estimation table of detection reaction patterns and existence areas of the infrared sensor. FIG. 25 is a detection area division diagram of the floor surface by the infrared sensor and the vertical wind direction plate.

図17〜図20に示す4つの検知動作によって得られた結果を、空気調和機から見て室内の奥行き方向の区分に対応させると、図21のようになる。上側上下風向板291を上側上下風向板位置491jで停止させて在室者の有無を検知する場合は、赤外線検知装置410の視野が検知範囲591jに限られるので、概略、検知エリア691Jの在室者を検知することになる。また、上側上下風向板291を上側上下風向板位置491kで停止させて在室者の有無を検知する場合は、赤外線検知装置410の視野が検知範囲591kに広がるので、概略、検知エリア691J,Kの在室者を検知することになる。上側上下風向板291を上側上下風向板位置491mで停止させて在室者の有無を検知する場合は、赤外線検知装置410の視野が検知範囲591mに広がるので、概略、検知エリア691J,K,Mの在室者を検知することになる。上側上下風向板291を上側上下風向板位置491nで停止させて在室者の有無を検知する場合は、赤外線検知装置410の視野が遮られることなく、検知範囲591nに広がるので、全ての検知エリア691J,K,M,Nの在室者を検知することになる。   When the results obtained by the four detection operations shown in FIGS. 17 to 20 are made to correspond to the sections in the depth direction of the room as viewed from the air conditioner, FIG. 21 is obtained. When the upper vertical wind direction plate 291 is stopped at the upper vertical wind direction plate position 491j to detect the presence or absence of an occupant, the field of view of the infrared detection device 410 is limited to the detection range 591j. Will be detected. When the upper vertical wind direction plate 291 is stopped at the upper vertical wind direction plate position 491k to detect the presence / absence of a room occupant, the field of view of the infrared detection device 410 extends to the detection range 591k. Will be detected. When detecting the presence / absence of an occupant by stopping the upper vertical wind direction plate 291 at the upper vertical wind direction plate position 491m, the field of view of the infrared detection device 410 extends to the detection range 591m. Will be detected. When the upper vertical wind direction plate 291 is stopped at the upper vertical wind direction plate position 491n to detect the presence or absence of a room occupant, the field of view of the infrared detection device 410 is not obstructed and extends to the detection range 591n. 691J, K, M, N occupants will be detected.

上述の検知エリアを床面での広がりで見ると図22のようになり、室内の奥行き方向に検知エリアを区分することができる。上述の説明では、説明を簡単にするため、検知エリアの境界を検知範囲の境界が床面に達する位置としたが、実際に、赤外線検知装置410が検知しやすい、人の顔,首筋の位置や人が立上がっているのか,椅子に座っているのか,床に座っているのか,寝ているのかなどの違いにより、検知エリアの境界線を厳密に求めるのは難しい。しかし、大まかには人が室内の遠いところに存在する,中位のところに存在する,近くに存在する,すぐ下に存在するのような区分けは十分可能である。空気調和機の空気調和範囲も目的とした場所を中心とした広がりを持つので、前述のような区分けに応じた空気調和でも十分な効果を奏する。   When the above-described detection area is viewed as spread on the floor, the detection area is as shown in FIG. 22, and the detection area can be divided in the depth direction of the room. In the above description, for the sake of simplicity, the boundary of the detection area is defined as the position where the boundary of the detection range reaches the floor surface. However, the position of the human face and neck that is actually easy for the infrared detection device 410 to detect. It is difficult to determine the boundaries of the detection area precisely because of differences in whether people are standing up, sitting on a chair, sitting on the floor, or sleeping. However, it is possible to roughly classify humans as far away in the room, in the middle, in the vicinity, or in the immediate vicinity. Since the air-conditioning range of the air conditioner has an expanse centered on the intended place, even air-conditioning according to the above-mentioned classification has a sufficient effect.

図23は、図17〜図20の4つの検知動作から得られる在室者有無の検知反応を示した表である。人のいるエリアが1つの場合、検知エリア691Jに人がいると、上側上下風向板291が上側上下風向板位置491j,k,m,nにあるときに在室者「有」の反応が現われる。同様に、検知エリア691Kに人がいると、上側上下風向板291が上側上下風向板位置491k,m,nにあるときに在室者「有」の反応が現われる。また、人のいるエリアが2つの場合、検知エリア691Jと検知エリア691Kに人がいると、上側上下風向板291が上側上下風向板位置491j,k,m,nにあるときに在室者「有」の反応が現われる。この様子を図23の検知反応の欄に風向板の位置毎に○印で表した。図23には各エリア毎の人の「有」「無」を組合わせた全ての組合わせ16通りの検知反応を纏め、同じ風向板の位置で「有」の反応になる存在エリアの組合わせに同じ検知反応パターンの名称を付した。この検知反応パターンの名称はa〜eの5種類になり、在室者の位置は5種類のパターンの中の1つとして識別される。   FIG. 23 is a table showing the presence / absence detection reaction obtained from the four detection operations of FIGS. In the case where there is one person, if there is a person in the detection area 691J, when the upper up / down wind direction plate 291 is at the upper up / down wind direction plate position 491j, k, m, n, a reaction of “resident” appears. . Similarly, when there is a person in the detection area 691K, a reaction of “having a room” appears when the upper vertical wind direction plate 291 is at the upper vertical wind direction plate position 491k, m, n. In the case where there are two people, if there are people in the detection area 691J and the detection area 691K, the occupant “when the upper vertical wind direction plate 291 is at the upper vertical wind direction plate position 491j, k, m, n” “Yes” appears. This state is indicated by a circle for each position of the wind direction plate in the detection reaction column of FIG. FIG. 23 summarizes all 16 combinations of “Yes” and “No” human detection responses for each area, and combinations of existing areas that have a “Yes” response at the same wind direction plate position. Are given the same detection reaction pattern names. There are five types of names of the detection reaction patterns a to e, and the position of the occupant is identified as one of the five types of patterns.

上記の検知反応パターン毎の人の存在エリアを図24の表に纏めた。図24に示すように、1つの検知反応パターンに対して人の存在エリアの複数の組合わせがあり、厳密には人の存在エリアを特定することは難しい。本実施例においては、同じ検知反応パターンを示す人の存在エリアの組合わせを、1つのグループにして推定存在エリアとした。これによれば、赤外線検知装置が検知したもっとも遠方のエリアから空気調和機の直下のエリアまでのすべてのエリアに人が存在するとみなし、空気調和機を制御する。これは、空気調和機は室内の空気を吸い込んで、調整した空気を再び室内に送風することにより室内を空気調和するものであるが、空気調和機から目的位置に向けて吹き出した風は目的位置を空気調和すると共に、循環して空気調和機に吸い込まれる間に、目的位置から空気調和機までの室内を結果として空気調和することとなる。従って、赤外線検知装置により検知した最も遠方のエリアにいる人に向けて空気調和機を制御することで、室内を在室者の存在エリアに適合した空気調和状態にすることができる。   The area of human presence for each detection reaction pattern is summarized in the table of FIG. As shown in FIG. 24, there are a plurality of combinations of human existence areas for one detection reaction pattern, and strictly speaking, it is difficult to specify the human existence area. In this example, the combination of the presence areas of people showing the same detection reaction pattern is made into one group as the estimated presence area. According to this, it is considered that there is a person in all areas from the farthest area detected by the infrared detection device to the area immediately below the air conditioner, and the air conditioner is controlled. This is because the air conditioner inhales the air in the room and blows the adjusted air into the room again to air-condition the room, but the wind blown from the air conditioner toward the target position As a result, the room from the target position to the air conditioner is air conditioned while being circulated and sucked into the air conditioner. Therefore, by controlling the air conditioner toward the person in the farthest area detected by the infrared detection device, the room can be brought into an air-conditioned state suitable for the presence area of the occupant.

これにより、推定存在エリアは検知反応パターンaの場合は、室内に在室者が無しと推定する(推定存在エリア;無)、検知反応パターンbの場合は、全ての検知エリアに在室者が存在すると推定する(推定存在エリア;JKMN)、検知反応パターンcの場合は、室内の中央部から空気調和機側に在室者が存在すると推定する(推定存在エリア;KMN)、検知反応パターンdの場合は、空気調和機に近い所と空気調和機の直下に在室者が存在すると推定する(推定存在エリア;MN)、検知反応パターンeの場合は、空気調和機直下にのみ在室者が存在すると推定する(推定存在エリア;N)、とみなして空気調和機を制御する。   Thus, if the estimated presence area is the detection reaction pattern a, it is estimated that there is no occupant in the room (estimated existence area; none). In the case of the detection reaction pattern b, occupants are present in all the detection areas. In the case of the detection reaction pattern c that is estimated to be present (estimated presence area; JKMN), it is estimated that a resident is present on the air conditioner side from the center of the room (estimated presence area; KMN). In the case of, it is estimated that there is a resident in the place close to the air conditioner and directly under the air conditioner (estimated existence area: MN). In the case of the detection reaction pattern e, the resident is only under the air conditioner. The air conditioner is controlled by assuming that the air conditioner exists (estimated presence area; N).

このように、本実施例においては、図9に示した複数の赤外線センサを用いて室内を左右方向に区分し、上側上下風向板を用いて赤外線センサを段階的に遮蔽することにより室内を前後方向(遠近方向)に区分することにより、図25に示すように室内を前後左右に交差検知エリア710JAB〜NCの18領域に区分する。つまり、予め用意された赤外線センサの遮蔽度合いと在室者が存在する位置との関係から、段階的に遮蔽された赤外線センサからの情報(図17〜図20に示す4つの検知動作によって得られた結果)に基づいて、在室者の位置を推定する。これにより、在室者の存在する位置を推定でき、その結果、空気調和機を適切に制御することができる。具体的には、在室者が存在する空間に対して空調するに際して、空気調和機の能力,風量,風向を制御する。これにより、在室者に快適な気流を送風する空気調和機を提供することができる。   As described above, in this embodiment, the room is divided into the left and right directions using the plurality of infrared sensors shown in FIG. 9, and the infrared sensors are shielded stepwise by using the upper vertical wind direction plate to move the room forward and backward. By dividing into directions (far and near directions), as shown in FIG. 25, the room is divided into 18 areas of intersection detection areas 710JAB to NC in the front-rear and left-right directions. In other words, information from the infrared sensor shielded in stages (obtained by the four detection operations shown in FIGS. 17 to 20) from the relationship between the degree of shielding of the infrared sensor prepared in advance and the position where the occupant is present. Based on the result, the position of the occupant is estimated. Thereby, the position where the occupant is present can be estimated, and as a result, the air conditioner can be appropriately controlled. Specifically, when air-conditioning a space where a resident is present, the capacity, air volume, and wind direction of the air conditioner are controlled. Thereby, the air conditioner which blows a comfortable air current to the occupants can be provided.

なお、本実施例においては、図17〜図20に示すように、在室者の位置を推定する人検知モードのときには、まず、上側上下風向板により赤外線センサを遮蔽し、その後、段階的に遮蔽度合いを減少させるようにしたが、まず、上側上下風向板が赤外線センサを遮蔽しない位置とし、その後、段階的に遮蔽度合いを増大させるようにしてもよい。段階的に遮蔽度合いを減少させるようにしても、段階的に遮蔽度合いを増大させるようにしても、またはランダムに遮蔽度合いを変化させるようにしても、異なる遮蔽度合いにおける赤外線センサからの情報を得ることにより、在室者の位置を推定することができる。本実施例においては、段階的に遮蔽度合いを減少させること、段階的に遮蔽度合いを増大させること、及びランダムに遮蔽度合いを変化させること等を含め、赤外線センサの視野を異なる遮蔽度合いとすることを、「赤外線センサの視野を段階的に遮蔽する」という。   In this embodiment, as shown in FIGS. 17 to 20, in the human detection mode for estimating the position of the occupant, first, the infrared sensor is shielded by the upper vertical wind direction plate, and then stepwise. Although the shielding degree is decreased, first, the upper vertical wind direction plate may be set to a position where the infrared sensor is not shielded, and then the shielding degree may be increased stepwise. Whether the degree of shielding is decreased stepwise, the degree of shielding is increased stepwise, or the degree of shielding is changed randomly, information from infrared sensors at different shielding degrees is obtained. Thus, the position of the occupant can be estimated. In this embodiment, the field of view of the infrared sensor is set to a different degree of shielding, including gradually reducing the degree of shielding, gradually increasing the degree of shielding, and changing the degree of shielding randomly. Is referred to as “shielding the field of view of the infrared sensor step by step”.

また、本実施例においては、赤外線センサにより在室者が存在する位置を検知する際(人検知モード)、空気調和機の風量を通常運転時より弱めることもできる。これにより、人検知モードの際に上側上下風向板が動いて風向が変わっても、風量を弱めているため、意図にそぐわない気流が在室者に到達するのことを抑制することができる。   Further, in this embodiment, when the position where the occupant is present is detected by the infrared sensor (person detection mode), the air volume of the air conditioner can be made weaker than during normal operation. Thereby, even if the upper vertical wind direction plate moves in the human detection mode and the wind direction changes, the air volume is weakened, so that it is possible to prevent unintended airflow from reaching the occupant.

また、本実施例においては、赤外線センサとして焦電型赤外線センサを用いることができる。これにより、安価なセンサと安価な構成で、在室者の位置を検知することができる。また、本実施例においては、赤外線センサをサーモパイルとすることができる。これにより、静止状態の在室者でも正確に検知できるので、在室者の位置に応じて空気調和機を適正に制御することができる。   In this embodiment, a pyroelectric infrared sensor can be used as the infrared sensor. Accordingly, the position of the occupant can be detected with an inexpensive sensor and an inexpensive configuration. In this embodiment, the infrared sensor can be a thermopile. Accordingly, even a resident in a stationary state can accurately detect the air conditioner, so that the air conditioner can be appropriately controlled according to the position of the resident.

また、本実施例においては、上側上下風向板を、在室者の位置を検知するために赤外線センサの視野を段階的に遮蔽するシャッターの代わりに使用することで、専用のシャッター機構等を不要とすることができる。   In this embodiment, the upper vertical wind direction plate is used in place of the shutter that blocks the infrared sensor field of view in order to detect the position of the occupant, thereby eliminating the need for a dedicated shutter mechanism. It can be.

本発明に係る第2の実施例について図26〜図28を用いて説明する。本実施例は、赤外線センサの数を2つにしたものである。図26は実施例2の室内機の赤外線センサの水平配置図である。図27は実施例2の赤外線センサの検知領域区分図である。図28は実施例2の赤外線センサと上下風向板による床面の検知領域区分図である。   A second embodiment according to the present invention will be described with reference to FIGS. In this embodiment, the number of infrared sensors is two. FIG. 26 is a horizontal layout diagram of the infrared sensor of the indoor unit according to the second embodiment. FIG. 27 is a detection area division diagram of the infrared sensor according to the second embodiment. FIG. 28 is a detection area division diagram of the floor surface by the infrared sensor and the up / down wind direction plate of the second embodiment.

赤外線検知装置410は、図26に示すように2個の赤外線センサ410a,cを台座415を介して、基板416に搭載する。各赤外線センサ410a,cは台座415により検知する方向を異ならせ、広角に検知範囲を構成し、さらに各赤外線センサ410a,cを俯角をもって実装するのは実施例1と同様である。これにより、室内床面の大半をその視野内に収め、室内を簡略に区分することができる。   As shown in FIG. 26, the infrared detection device 410 has two infrared sensors 410 a and 410 c mounted on a substrate 416 via a pedestal 415. Similar to the first embodiment, the infrared sensors 410a, c have different detection directions by the pedestal 415, form a wide detection range, and mount the infrared sensors 410a, c with depression angles. As a result, most of the indoor floor surface can be accommodated within the field of view, and the room can be simply divided.

図27は検知領域区分図であり、赤外線センサ410a,cが検知する検知エリア610A,C,赤外線センサ410a,cが重複して検知する検知エリア610ACに区分される。赤外線センサ410aのみが検知した場合は、検知エリア610Aに人体が存在すると推定する。赤外線センサ410cのみが検知した場合は、検知エリア610Cに人体が存在すると推定する。赤外線センサ410a及び赤外線センサ410cが検知した場合は、検知エリア610ACに人体が存在していると推定する。   FIG. 27 is a detection area division diagram, and is divided into detection areas 610A, C detected by the infrared sensors 410a, c, and detection areas 610AC detected by the infrared sensors 410a, c overlapping. When only the infrared sensor 410a detects, it estimates that a human body exists in the detection area 610A. When only the infrared sensor 410c detects, it is estimated that a human body exists in the detection area 610C. When the infrared sensor 410a and the infrared sensor 410c detect, it is estimated that the human body exists in the detection area 610AC.

このように、本実施例においては、図26に示した複数の赤外線センサを用いて室内を左右方向に区分し、上側上下風向板を用いて室内を前後方向に区分することにより、図28に示すように室内を前後左右に交差検知エリア710JAB〜NCの12領域に区分する。これにより、在室者の存在する位置を推定でき、赤外線センサの数を2個に減じても、空気調和機を適切に制御することができる。   As described above, in this embodiment, the room is divided in the left-right direction using the plurality of infrared sensors shown in FIG. 26, and the room is divided in the front-rear direction using the upper vertical wind direction plate. As shown, the room is divided into 12 areas of intersection detection areas 710JAB to NC in the front-rear and left-right directions. Thereby, the position where the occupant is present can be estimated, and the air conditioner can be appropriately controlled even if the number of infrared sensors is reduced to two.

本発明に係る第3の実施例を図29〜図31を用いて説明する。本実施例は、人の存在するエリアの前後方向(遠近方向)の識別を細分化したものである。図29は実施例3の室内機の上下風向板による検知領域説明図である。図30は実施例3の存在エリアと赤外線センサの検知反応を示す表である。図31は実施例3の赤外線センサの検知反応パターンと存在エリアの推定表である。   A third embodiment according to the present invention will be described with reference to FIGS. In this embodiment, the identification in the front-rear direction (far-near direction) of an area where a person exists is subdivided. FIG. 29 is an explanatory diagram of detection areas by the up and down wind direction plates of the indoor unit of the third embodiment. FIG. 30 is a table showing the presence area of Example 3 and the detection reaction of the infrared sensor. FIG. 31 is an estimation table of detection reaction patterns and existence areas of the infrared sensor of Example 3.

本実施例では、実施例1の上側上下風向板の翼長を短くし、図29に示すように、上側上下風向板位置491iにおいて、空気調和機の直下の検知エリア691Nを赤外線検知装置410の視野に開放した。これにより、上側上下風向板位置491i〜nにおける赤外線検知装置410の検知反応は図30のようになり、検知反応パターンはa〜d,b′〜e′の8パターンになる。この8パターンに対する推定存在エリアを、図31に示すように、推定存在エリア無から推定存在エリアJKMNと推定することにより、実施例1より存在エリアを細分化することができる。   In the present embodiment, the blade length of the upper vertical wind direction plate of the first embodiment is shortened, and as shown in FIG. 29, the detection area 691N immediately below the air conditioner is placed in the infrared detection device 410 at the upper vertical wind direction plate position 491i. Open to the field of view. Thereby, the detection reaction of the infrared detection device 410 at the upper vertical wind direction plate positions 491i to n is as shown in FIG. 30, and the detection reaction patterns are eight patterns a to d and b 'to e'. As shown in FIG. 31, it is possible to subdivide the existence area from the first embodiment by estimating the estimated existence area for the eight patterns as the estimated existence area JKMN from the absence of the estimated existence area.

第4の実施例を図32〜図35を用いて説明する。本実施例は、赤外線センサを左右風向板により遮蔽することにより、左右方向の在室者の存在領域を推定するものである。図32は実施例4の空気調和機の室内機の側断面図である。図33は実施例4の左右風向板による検知領域説明図であり、(a)は最左方領域検知位置を示す図、(b)は左方領域検知位置を示す図、(c)は中央領域検知位置を示す図、(d)は右方領域検知位置を示す図、(e)は最右方領域検知位置を示す図である。図34は実施例4の左右風向板による床面の検知領域区分図である。図35は実施例4の上下及び左右風向板による床面の検知領域区分図である。   A fourth embodiment will be described with reference to FIGS. In this embodiment, the presence area of the occupant in the left-right direction is estimated by shielding the infrared sensor with the left and right wind direction plates. FIG. 32 is a side sectional view of the indoor unit of the air conditioner according to the fourth embodiment. FIGS. 33A and 33B are explanatory diagrams of detection areas by the left and right wind direction plates of Example 4. FIG. 33A is a diagram showing the leftmost area detection position, FIG. 33B is a diagram showing the left area detection position, and FIG. The figure which shows an area | region detection position, (d) is a figure which shows a right side area | region detection position, (e) is a figure which shows a rightmost area | region detection position. FIG. 34 is a detection area division diagram of the floor surface by the left and right wind direction plates of the fourth embodiment. FIG. 35 is a detection area division diagram of the floor surface by the upper and lower and right and left wind direction plates of the fourth embodiment.

図32に示すように、本実施例は、実施例1の赤外線検知装置の赤外線センサを単一の広角赤外線センサにし、左右風向板の中央部の羽根の吹き出し側先端を赤外線センサの視野を遮蔽するように吹出風路上方拡大部まで延伸したものである。左右風向板295を正面にむけた左右風向板位置495rにしたときには、図33(c)のように、赤外線検知装置410の視野は左右風向板295に遮られて、検知範囲595rとなる。同様に、左右風向板295を左右風向板位置495p,q,s,tにしたときには、図33(a)(b)(d)(e)のように、赤外線検知装置410の視野は左右風向板295に遮られて、検知範囲595p,q,s,tとなる。   As shown in FIG. 32, in this embodiment, the infrared sensor of the infrared detecting device of the first embodiment is changed to a single wide-angle infrared sensor, and the blowing side tip of the blade at the center of the left and right wind direction plates is shielded from the field of view of the infrared sensor. Thus, it extends to the upper part of the blowout air path. When the left / right wind direction plate 295 is set to the left / right wind direction plate position 495r facing the front, as shown in FIG. 33 (c), the field of view of the infrared detecting device 410 is blocked by the left / right wind direction plate 295, and becomes the detection range 595r. Similarly, when the left and right wind direction plates 295 are set to the left and right wind direction plate positions 495p, q, s, and t, as shown in FIGS. 33 (a), (b), (d), and (e), the field of view of the infrared detection device 410 is the left and right wind directions. The detection range is 595p, q, s, t by being blocked by the plate 295.

図34に示すように、これらの範囲を室内の床面で表すと、左右風向板位置495pで検知される検知エリア695P,左右風向板位置495p,qの両方で検知される検知エリア695PQ,左右風向板位置495qで検知される検知エリア695Q,左右風向板位置495q,rの両方で検知される検知エリア695QR,左右風向板位置495r,sの両方で検知される検知エリア695RS,左右風向板位置495sで検知される検知エリア695S,左右風向板位置495s,tの両方で検知される検知エリア695ST,左右風向板位置495tで検知される検知エリア695Tの8エリアになる。図22に示す前後方向(遠近方向)のエリア区分と上述の左右方向のエリア区分により、室内を図35に示す交差検知エリア730JPQ〜NTの30エリアに区分することができる。   As shown in FIG. 34, when these ranges are represented by indoor floors, the detection area 695P detected at the left and right wind direction plate position 495p, the detection area 695PQ detected at both the left and right wind direction plate positions 495p, q, Detection area 695Q detected at wind direction plate position 495q, detection area 695Q detected at both left and right wind direction plate positions 495q, r, detection area 695RS detected at both left and right wind direction plate positions 495r, s, left and right wind direction plate positions There are 8 areas: a detection area 695S detected at 495s, a detection area 695ST detected at both the left and right wind direction plate positions 495s, t, and a detection area 695T detected at the left and right wind direction plate positions 495t. The room can be divided into 30 areas of intersection detection areas 730JPQ to NT shown in FIG. 35 based on the front and rear direction (far-near direction) area division and the above-described left and right area division shown in FIG.

本実施例では、左右風向板により赤外線センサを遮蔽する。これにより、専用のシャッター機構等が不要となり、左右風向板の駆動機構を利用し安価に検知領域を区分することができる。   In this embodiment, the infrared sensor is shielded by the left and right wind direction plates. As a result, a dedicated shutter mechanism or the like is not required, and the detection area can be divided at low cost by using the drive mechanism of the left and right wind direction plates.

尚、本実施例において、垂直方向に配置された複数の赤外線センサを空気調和機に搭載し、この垂直方向に配置された複数の赤外線センサにより遠近方向のエリアを区分してもよい。つまり、図22に示す遠近方向のエリア区分を用いずに、垂直方向に展開した複数の赤外線センサにより室内の遠近方向のエリアを区分し、左右風向板により赤外線センサを段階的に遮蔽して左右方向のエリアを区分することにより、在室者の位置を推定することもできる。   In this embodiment, a plurality of infrared sensors arranged in the vertical direction may be mounted on the air conditioner, and the area in the perspective direction may be divided by the plurality of infrared sensors arranged in the vertical direction. That is, without using the perspective area division shown in FIG. 22, the indoor perspective area is divided by a plurality of infrared sensors deployed in the vertical direction, and the infrared sensors are shielded stepwise by the left and right wind direction plates.
