まず、空気調和機の全体構成について図1,図2を用いて説明する。図1は実施例の空気調和機の構成図である。図2は空気調和機の室内機の断面図である。   First, the whole structure of an air conditioner is demonstrated using FIG. 1, FIG. FIG. 1 is a configuration diagram of an air conditioner according to an embodiment. FIG. 2 is a sectional view of the 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、筐体ベース21の中央部に室内熱交換器33を置き、熱交換器33の下流側に熱交換器33の幅と略等しい長さの横流ファン方式の室内送風機311を配置し、露受皿35等を取り付け、これらを化粧枠23で覆い、化粧枠23の前面に前面パネル25を取り付けている。この化粧枠23には、室内空気を吸い込む空気吸込み口27と、温湿度が調整された空気を吹出す空気吹出し口29とが上下に設けられている。室内熱交換器33の空気流下流には室内送風機311が設けられ、室内送風機311が回転すると室内空気が室内機2に設けられた空気吸込み口27から室内熱交換器33,室内送風機311を通って室内送風機311の長さに略等しい幅を持つ吹出し風路290に流れ、吹出し風路290途中に配した左右風向板295で気流の左右方向を偏向され、更に、吹出し口29に配した上下風向板291,292で気流の上下方向を偏向されて室内に吹出す。   The air conditioner 1 connects the indoor unit 2 and the outdoor unit 6 with a connection pipe 8 to air-condition the room. In the indoor unit 2, an indoor heat exchanger 33 is placed at the center of the casing base 21, and a cross-flow fan type indoor blower 311 having a length substantially equal to the width of the heat exchanger 33 is disposed downstream of the heat exchanger 33. Then, a dew tray 35 and the like are attached, these are covered with a decorative frame 23, and a front panel 25 is attached to the front surface of the decorative frame 23. The decorative frame 23 is provided with an air inlet 27 for sucking in indoor air and an air outlet 29 for blowing air with adjusted temperature and humidity. An indoor blower 311 is provided downstream of the air flow of the indoor heat exchanger 33, and when the indoor blower 311 rotates, indoor air passes through the indoor heat exchanger 33 and the indoor blower 311 from the air inlet 27 provided in the indoor unit 2. The left and right airflow direction plates 295 arranged in the middle of the blowout air passage 290 are deflected in the left-right direction of the airflow, and further, The up and down direction of the airflow is deflected by the wind direction plates 291 and 292 and blown out into the room.

筐体ベース21には、室内送風機311,フィルタ231,231′,室内熱交換器33,露受皿35,上下風向板291,292,左右風向板295等の基本的な内部構造体が取り付けられ、これらの基本的な内部構造体は、筐体ベース21,化粧枠23,前面パネル25からなる筐体20に内包され室内機2を構成する。   Basic internal structures such as an indoor blower 311, filters 231 and 231 ′, an indoor heat exchanger 33, a dew tray 35, vertical wind direction plates 291 and 292, and left and right wind direction plates 295 are attached to the housing base 21. These basic internal structures are included in a casing 20 including a casing base 21, a decorative frame 23, and a front panel 25, and constitute the indoor unit 2.

また、前面パネル25の下部一側には、運転状況を表示する表示装置397と、別体のリモコン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。   In addition, a display device 397 for displaying an operation status and a light receiving unit 396 for receiving an infrared operation signal from a separate remote controller 5 are disposed on the lower side of the front panel 25.

化粧枠23の下面に形成される空気吹出し口29は、前面パネル25との分割部に隣接して配置され、奥の吹出し風路290に連通している。2枚の上下風向板291,292は、閉鎖状態で、吹出し風路290をほぼ隠蔽して室内機2の底面に連続する大きな曲面を有するように構成されている。これらの上下風向板291,292は、両端部に設けた回動軸を支点にして、リモコン5からの指示に応じて、駆動モータにより空気調和機1の運転時に所要の角度回動して空気吹出し口29を開き、その状態に保持する。空気調和機1の運転停止時には、これらの上下風向板291,292は空気吹出し口29を閉じるように制御される。   An 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 rear outlet air passage 290. The two up-and-down air direction plates 291 and 292 are configured to have a large curved surface continuous with the bottom surface of the indoor unit 2 while substantially concealing the blowing air passage 290 in a closed state. These up-and-down wind direction plates 291 and 292 are rotated by a required angle at the time of operation of the air conditioner 1 by a drive motor in response to an instruction from the remote controller 5 with the rotation shafts provided at both ends as fulcrums. The air outlet 29 is opened and held in that state. When the operation of the air conditioner 1 is stopped, the up-and-down air direction plates 291 and 292 are controlled so as to close the air outlet 29.

左右風向板295は、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、リモコン5からの指示の応じて回動されてその状態に保持される。これによって、吹出し空気が左右の所望の方向に吹出される。なお、リモコン5から指示することにより、空気調和機1の運転中に上下風向板291,292、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出し空気を送ることもできる。   The left and right wind direction plates 295 are rotated by a drive motor with a rotation shaft provided at the lower end portion as a fulcrum, and are rotated in accordance with an instruction from the remote controller 5 and held in that state. As a result, the blown air is blown out in the left and right desired directions. By instructing from the remote controller 5, the up and down wind direction plates 291 and 292 and the left and right wind direction plates 295 are periodically oscillated during the operation of the air conditioner 1, and the blown air is periodically sent over a wide range in the room. it can.

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ている。これによって、室内空気は、運転時に前側空気吸込み部230′からも室内機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′は閉じるように制御される。   The movable panel 251 is configured to be rotated by a drive motor with a rotation shaft provided at a lower portion as a fulcrum, and to open the front air suction portion 230 ′ when the air conditioner 1 is operated. As a result, the indoor air is also sucked into the indoor unit 2 from the front air suction portion 230 'during operation. When the air conditioner 1 is stopped, the front air suction portion 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けると共に、リモコン5からの操作信号を受光部396を介して受ける。このマイコンは、これらの信号に基づいて、室内送風機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 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 the communication with the outdoor unit 6. Control all over.

フィルタ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ためのものであり、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ために設けられている。受けて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 ′ are for removing dust contained in the sucked indoor 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 is provided to receive condensed water generated in the indoor heat exchanger 33 during cooling operation or dehumidifying operation. The condensed water received and collected is discharged to the outside through the drain pipe 37.

次に、上下風向板について図3,図4を用いて説明する。図3は室内機の冷房・除湿運転時の断面図である。図4は室内機の暖房運転時の断面図である。   Next, an up-and-down wind direction board is demonstrated using FIG. 3, FIG. FIG. 3 is a cross-sectional view of the indoor unit during the cooling / dehumidifying operation. FIG. 4 is a cross-sectional view of the indoor unit during heating operation.

上下風向板は前述のように上側上下風向板291,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、下側上下風向板について述べる時は下側上下風向板と記すこととする。   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 the present specification, the upper vertical wind direction plate 291 will be 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 when the lower vertical wind direction plate is described. .

上下風向板291は空気吹出し口29の上部の横幅いっぱい設けられ、上下風向板駆動モータ(図示せず)により、吹出し空気を下吹出し、あるいは水平吹出しなどに偏向する。   The vertical wind direction plate 291 is provided in the full width of the upper part of the air outlet 29, and the vertical air direction plate drive motor (not shown) deflects the blown air downward or horizontal.

空気調和機を使用しない運転停止時は図2のように、上側上下風向板291,下側上下風向板292,可動パネル251は制御装置により空気吹出し口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は吹出し風路290の上方拡大部290eの前方の位置に回動し収納され、風路上方拡大部290eを遮蔽し、下側上下風向板292と協働して吹出し口29を閉じる。   When the operation is stopped without using the air conditioner, as shown in FIG. 2, the upper vertical wind direction plate 291, the lower vertical wind direction plate 292, and the movable panel 251 are controlled by the control device so as to close the air outlet 29. As a result, the upper vertical wind direction plate 291 is rotated and stored at a position in front of the upper enlarged portion 290e of the blowout air passage 290, shields the upper upward air flow portion 290e, and cooperates with the lower vertical wind direction plate 292. The outlet 29 is closed.

この風路上方拡大部290eのほぼ中央に後述する赤外線検知装置14が設けられている。   An infrared detection device 14 to be described later is provided substantially at the center of the air path upper enlarged portion 290e.

このとき、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位置するため、外面となる外側風向面291aは滑らで曲率の大きい曲面にして空気調和機の外形に合致させる。このようにすることにより、上側上下風向板291、下側上下風向板292は外面となる風向面で空気調和機の前面から底面にかけての外形を連続的に滑らかに形成することができる。   At this time, since the upper vertical wind direction plate 291 is located at the intersection of the front surface and the bottom surface of the air conditioner, the outer wind direction surface 291a serving as the outer surface is a smooth curved surface having a large curvature to match the outer shape of the air conditioner. By doing in this way, the upper up-and-down wind direction board 291 and the lower up-and-down wind direction board 292 can form the outer shape from the front to the bottom of the air conditioner continuously and smoothly on the wind direction surface as the outer surface.

このため、空気調和機を使用しないとき、空気調和機の目とも言うべき赤外線検知装置14も上側上下風向板291によって目隠しされ、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。   For this reason, when the air conditioner is not used, the infrared detecting device 14 that should also be referred to as the air conditioner's eye is also blindfolded by the upper vertical wind direction plate 291, and the appearance of the air conditioner is soft and calm without unnecessary irregularities. It becomes a shape and does not disturb the indoor atmosphere.

空気調和機を冷房運転する時には図3のように上側上下風向板291,下側上下風向板292は吹出し風路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。また、吹出された冷風が直接、在室者に当って不快感を生じさせる場合は、適宜、上下風向板の方向をリモコンで変更し、在室者の周囲を快適な温湿度に保つ。   When the air conditioner is in a cooling operation, as shown in FIG. 3, the upper vertical wind direction plate 291 and the lower vertical wind direction plate 292 are used in a posture substantially parallel to the upper wall 290a and the lower wall 290b of the blowout air passage 290 or in a horizontal direction. Is done. In addition, when the blown cold air directly hits the occupant and causes discomfort, the direction of the up-and-down wind direction plate is changed with a remote controller as appropriate, 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なう時に上側上下風向板291を図26のようにやや上向きにし、下側上下風向板292を破線で示したようにほぼ閉じる姿勢にし、吹出し風路290の下流に設けた上方に拡大する上方拡大部290eに吹出し気流を流す。これにより、吹出し空気の一部が極弱い風となって上方拡大部290eを通ってふんわりと室内に拡散し、微弱な冷房または暖房を行う。   When performing extremely weak cooling or heating operation, the upper vertical wind direction plate 291 is slightly upward as shown in FIG. 26, and the lower vertical wind direction plate 292 is substantially closed as indicated by a broken line, and is provided downstream of the blowout air passage 290. The blown airflow is caused to flow through the upper enlarged portion 290e that expands upward. As a result, a part of the blown air becomes a very weak wind and gently diffuses through the upper enlarged portion 290e into the room to perform weak cooling or heating.

更に、上方拡大部290eを利用して、吹出した風をすぐさま、吸込み口27から吸込ませるショートサーキット運転を行うことで、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可能となる。   Furthermore, the air conditioner such as a heat exchanger drying operation or a deodorizing operation inside the air conditioner is performed by performing a short circuit operation in which the blown wind is immediately sucked from the suction port 27 using the upper enlarged portion 290e. It is also possible to perform the maintenance operation.

空気調和機を暖房運転する時には、上下風向板291,292は図4のようにほぼ垂直に近い姿勢にして使用される。このようにすることにより、吹出し風路290を流れる温風は空気調和機から下方に向かって吹出し、床面近くまで到達し、足もと近くを暖め、室内を快適な環境にする。   When heating the air conditioner, the up and down wind direction plates 291 and 292 are used in a substantially vertical posture as shown in FIG. By doing in this way, the warm air which flows through the blowing air path 290 blows out downward from an air conditioner, reaches | attains near a floor surface, warms near a foot | foot, and makes the room a comfortable environment.

一般に、空気調和機に人検知装置を取り付ける場合、その主たる目的は在室者が居ない時に空気調和機を省エネ運転または、停止し、在室者が少ない時には、その少ない人に向けて風を送るなどの専用運転をして省エネを図ると共に人の移動に伴う煩わしい操作を回避することである。   In general, when a human detection device is attached to an air conditioner, its main purpose is to save energy by operating or shutting down the air conditioner when there are no people in the room, and when there are few people in the air, The purpose is to save energy by carrying out a dedicated operation such as sending and avoiding troublesome operations associated with the movement of people.

これを実現するため、焦電型の赤外線センサなどを使用した人検知センサを複数個つけて、室内を複数の領域に区分し、在室者が空気調和機から見てどの位置に居るかを検知するようにしている。この場合、人検知センサの検知区域の間に非検知領域ができないように、人検知センサの検知区域が互いに重なるように設置することが行われている。   To achieve this, attach multiple human detection sensors using pyroelectric infrared sensors, etc. to divide the room into multiple areas and determine where the occupants are as viewed from the air conditioner. I try to detect it. In this case, installation is performed such that the detection areas of the human detection sensors overlap with each other so that a non-detection area is not formed between the detection areas of the human detection sensors.

このとき、唯一の人検知センサが反応した場合は、その人検知センサの検知区域に人が居ることが判るが、検知区域が重複する複数の赤外線センサが反応した時には、重複領域に集中して人が居る場合と、互いの排他的領域に人が分散して居る場合と、重複領域と片方の排他的領域に人が分散して居る場合と、重複領域と双方の排他的領域に人が分散して居る場合とが考えられ、これらの領域を区別するため、センサの数を増やすことや他の方式のセンサを取り付けて、互いの能力不足部分を補完することが行われている。   At this time, if the only human detection sensor reacts, it can be seen that there is a person in the detection area of the human detection sensor, but when multiple infrared sensors with overlapping detection areas react, they concentrate on the overlapping area. When there are people, when people are distributed in each other's exclusive area, when people are distributed in the overlapping area and one exclusive area, and when people are in the overlapping area and both exclusive areas In order to distinguish these areas, it is considered that the number of sensors is increased or other types of sensors are attached to complement each other's lack of capability.

実施例では図6のように赤外線検知装置14を前述の吹出し風路上方拡大部290eの長手方向の中央部に設け、運転停止時には図5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した。   In the embodiment, as shown in FIG. 6, the infrared detecting device 14 is provided at the center in the longitudinal direction of the above-described blowing air channel upper enlarged portion 290e, and when the operation is stopped, it is shielded from the room by the upper vertical airflow direction plate 291 as shown in FIG. I tried not to give the room a strange feeling.

赤外線検知装置14は、図7に示すように赤外線センサ410を台座415を介して、基板416に搭載しフレネルレンズ417を被せ、これを左右に配して図9のように構成する。   As shown in FIG. 7, the infrared detection device 14 is configured as shown in FIG. 9 by mounting an infrared sensor 410 on a substrate 416 via a base 415 and covering a Fresnel lens 417.

赤外線センサ410は平滑な受光面410−1を持ち、受光面410−1の対向する方向が主検知方向となり、受光面410−1の中心から主検知方向に向かう中心軸412は検知感度が最も良好な方向となり、その周りに検知感度の良好な検知範囲が広がる。   The infrared sensor 410 has a smooth light receiving surface 410-1, the direction in which the light receiving surface 410-1 faces is the main detection direction, and the center axis 412 from the center of the light receiving surface 410-1 toward the main detection direction has the highest detection sensitivity. It becomes a good direction, and a detection range with good detection sensitivity is spread around it.

左右の赤外線センサ410a,cは各前記台座415a,cにより、中心軸412a,cが図10のように中心軸交点401で交わり、且つ、その方向が異なるように搭載され、当然その主検知方向も異なるため、図8のように広角に検知範囲を構成でき、さらに赤外線検知装置14を図9(d)のように俯角をもって組込むことにより、室内床面の大半をその視野内に収めることができる。   The left and right infrared sensors 410a, c are mounted by the pedestals 415a, c so that the central axes 412a, c intersect at the central axis intersection 401 as shown in FIG. Therefore, the detection range can be configured at a wide angle as shown in FIG. 8, and by incorporating the infrared detector 14 with a depression angle as shown in FIG. 9 (d), most of the indoor floor can be accommodated within the field of view. it can.

実施例では左右2個の赤外線センサ410を使用するので、これを符号で区別するため、以下、左方の赤外線センサ410aに関連する部分には符号の後にaを追加し、右方の赤外線センサ410cに関連する部分には符号の後にcを追加して、例えば、左方の受光面は410−1aの如く、右方の中心軸は412cの如くに表す。   In the embodiment, since the left and right infrared sensors 410 are used, in order to distinguish them by reference numerals, hereinafter, a is added to the part related to the left infrared sensor 410a and the right infrared sensor. For example, the left light-receiving surface is represented as 410-1a and the right central axis is represented as 412c.

また、説明を簡略にするため、図11の(a)のように、両中心軸412を含む平面を中心軸平面421と言い、図11の(b)のように、中心軸平面421と中心軸412で垂直に交わる平面を中心軸直交平面422と言い、図12の(a)のように、中心軸412a,cが作る角の基板416に垂直な2等分線(装置中央軸)402で中心軸平面421に垂直に交わる平面を中央直交平面423と言い、図12の(b)のように、中心軸412と基板416前面の台座搭載面416−14との交点416−8a,cを通る中央直交平面423と平行な平面を装着直交平面424と言い、組立て後は同一の平面になるが、中心軸412と台座415の基板装着面415−7との交点となる装着面中心415−8を通る中央直交平面423と平行な平面を搭載直交平面424と言う。   For the sake of simplicity, a plane including both central axes 412 is referred to as a central axis plane 421 as shown in FIG. 11A, and the central axis plane 421 and the center as shown in FIG. A plane perpendicular to the axis 412 is referred to as a central axis orthogonal plane 422, and a bisector (device central axis) 402 perpendicular to the corner substrate 416 formed by the central axes 412a and c as shown in FIG. The plane perpendicular to the central axis plane 421 is called a central orthogonal plane 423, and as shown in FIG. 12B, the intersection points 416-8a, c between the central axis 412 and the base mounting surface 416-14 on the front surface of the substrate 416. A plane parallel to the central orthogonal plane 423 passing through the center is referred to as a mounting orthogonal plane 424, which is the same plane after assembly, but the mounting surface center 415 that is the intersection of the central axis 412 and the substrate mounting surface 415-7 of the base 415. A central orthogonal plane 423 through −8; A row of plane say the mounting perpendicular to the plane 424.

基板416に赤外線センサ410a,cを取り付けるときは、先ず、台座415a,cの基板装着面415−7a,cを基板416の台座搭載面416−14に向け、台座中心軸415−12a,cが基板416の手前側で拡がるように台座415a,cを互いに反対向きにして、位置決め突起415−1a,cを基板416の位置決め孔416−1a,cに嵌入させる。次に、左右の赤外線センサ410a,cをセンサ突起410−4a,cが同じ向きになるようにして信号線410−3a,cを台座415a,cの信号線貫通孔415−3a,cと基板416の信号線貫通孔416−3a,cに挿入する。基板416の背面に突き出た信号線410−3a,cを適宜屈曲させ基板416に仮止めし、半田付けなどにより基板416に電気的、機械的に固定する。   When attaching the infrared sensors 410a, c to the substrate 416, first, the substrate mounting surfaces 415-7a, c of the pedestals 415a, c are directed to the pedestal mounting surfaces 416-14 of the substrate 416, and the pedestal central axes 415-12a, c are The positioning protrusions 415-1a, c are fitted into the positioning holes 416-1a, c of the substrate 416 with the pedestals 415a, c facing away from each other so as to expand on the front side of the substrate 416. Next, the left and right infrared sensors 410a, c are arranged in the same direction with the sensor protrusions 410-4a, c, and the signal lines 410-3a, c are connected to the signal line through holes 415-3a, c of the bases 415a, c and the substrate. 416 is inserted into the signal line through holes 416-3a, c. The signal lines 410-3a and c protruding from the back surface of the substrate 416 are appropriately bent, temporarily fixed to the substrate 416, and electrically and mechanically fixed to the substrate 416 by soldering or the like.

次に、フレネルレンズ417a,cの係着脚417−5a,cを台座415a,cのレンズ係着部415−5に差込んでフレネルレンズ417a,cを台座415a,cに係着する。この時、フレネルレンズ417a,cの受け部凹所417−6a,cが台座415a,cのレンズ受け部415−6a,cに遊着しフレネルレンズ410a,cを安定させる。   Next, the engaging legs 417-5a, c of the Fresnel lenses 417a, c are inserted into the lens engaging portions 415-5 of the bases 415a, c, and the Fresnel lenses 417a, c are engaged with the bases 415a, c. At this time, the receiving portion recesses 417-6a, c of the Fresnel lenses 417a, c are loosely attached to the lens receiving portions 415-6a, c of the pedestals 415a, c to stabilize the Fresnel lenses 410a, c.

次に、赤外線検知装置の検知領域と回路について図19,図20を用いて説明する。図19は検知装置による検知区域図である。図20は検知装置の回路構成図である。   Next, detection areas and circuits of the infrared detection device will be described with reference to FIGS. 19 and 20. FIG. 19 is a detection area diagram of the detection device. FIG. 20 is a circuit configuration diagram of the detection device.

この小フレネルレンズが赤外線を集光する方向を、座った時の顔の高さ付近の床と平行な面で示すと図19のような検知スポットの分布になり、この範囲を人が移動していくつかの検知スポットを出入りすると赤外線センサ410がこれを検知する。実施例では、家庭の室内で使われることを想定し、赤外線センサ410から6m離れた位置でのひとつの検知スポットの大きさが凡そ人体の大きさと同等(幅0.3〜0.5m,高さ1.6〜1.8m)になるように設定した。   When the direction in which the small Fresnel lens collects infrared rays is shown by a plane parallel to the floor near the height of the face when sitting, the detection spot distribution as shown in FIG. 19 is obtained. When several detection spots enter and exit, the infrared sensor 410 detects this. In the embodiment, assuming that the sensor is used in a room at home, the size of one detection spot at a position 6 m away from the infrared sensor 410 is approximately equal to the size of the human body (width 0.3 to 0.5 m, high 1.6 to 1.8 m).

実施例では赤外線センサ410として、焦電型の赤外線センサを用いる。赤外線検知装置14は図20に示すように左人検知センサ140aと右人検知センサ140cと演算制御部132からなり、左右の人検知センサ140a,cは赤外線センサ410a,c,赤外線センサ410a,cの出力を増幅する増幅器130,その出力をデジタル信号へと変換するコンパレータ131や前述の台座415,フレネルレンズ417などから構成されている。   In the embodiment, a pyroelectric infrared sensor is used as the infrared sensor 410. As shown in FIG. 20, the infrared detection device 14 includes a left person detection sensor 140a, a right person detection sensor 140c, and an arithmetic control unit 132. The left and right person detection sensors 140a, c are infrared sensors 410a, c, infrared sensors 410a, c. Amplifier 130, a comparator 131 for converting the output into a digital signal, the pedestal 415, the Fresnel lens 417, and the like.

一般に、人が覚醒している時には、生理的に静止し続けることはできず、数分の中で意識的にあるいは無意識のうちに手,脚,顔など体の一部を動かしている。   In general, when a person is awake, he cannot remain physiologically stationary, and moves a part of his body such as hands, legs and face consciously or unconsciously within a few minutes.

赤外線センサ410a,cはこの動きを検知し、信号を出力する。赤外線センサ410a,cからの出力は人検知センサ140で演算制御部132での処理に適した形態に変換されて演算制御部132に読み込まれ、演算処理の結果に応じて、空気調和機の能力,風向などの制御が行われる。   The infrared sensors 410a and 410c detect this movement and output a signal. Outputs from the infrared sensors 410a and 410c are converted into a form suitable for processing by the arithmetic control unit 132 by the human detection sensor 140 and read into the arithmetic control unit 132, and the capability of the air conditioner is determined according to the result of the arithmetic processing. The wind direction is controlled.

上記のように、赤外線検知装置14を構成すれば、前記焦電型赤外線センサ410a,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、前記増幅器130にて増幅し、前記コンパレータ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、前記演算制御部132の読み込みポートに入力され、前記演算制御部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領域に対し、前記上下風向板291,292,左右風向板295を向け、或いは、避けて室内送風機311によって、調和された空気が送風される。   As described above, if the infrared detection device 14 is configured, an analog signal is output from the pyroelectric infrared sensors 410a and 410c according to the environment, the presence of the human body, and the activity of the human body, and is 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 arithmetic control unit 132, and arithmetic processing is performed by the arithmetic control unit 132. As a result, conditioned air is blown by the indoor blower 311 by directing or avoiding the up-and-down wind direction plates 291 and 292 and the left and right wind direction plates 295 with respect to an area determined to have a human body.

次に、室内の人の移動による赤外線センサ410からの信号の変化について図21〜図23を用いて説明する。図21は室内に人が入室する時の動きを示す図である。図22は図15の場合の赤外線検知装置の波形出力、(a)は左赤外線センサ出力のアナログ波形、(b)は左人検知センサ出力のデジタル波形、(c)は右赤外線センサ出力のアナログ波形、(d)は右人検知センサ出力のデジタル波形である。図23は検知装置の検知領域区分図である。   Next, changes in the signal from the infrared sensor 410 due to the movement of a person in the room will be described with reference to FIGS. FIG. 21 is a diagram showing movement when a person enters the room. FIG. 22 shows the waveform output of the infrared detector in the case of FIG. 15, (a) is the analog waveform of the left infrared sensor output, (b) is the digital waveform of the left human sensor output, and (c) is the analog of the right infrared sensor output. Waveform (d) is a digital waveform of the right person detection sensor output. FIG. 23 is a detection area division diagram of the detection apparatus.

図21に示すように、室902に人907が位置Pから入室し、位置Q,Rを経て位置Sまで移動したとき、赤外線検知装置14の赤外線センサ410aは図22(a)のようなアナログ信号を出力する。このアナログ出力の絶対値が一定のレベルを越えた時に、活動パルス(実施例ではHiパルス)を出力するように、このアナログ出力を増幅器130,コンパレータ131などで処理して、図22(b)のようなデジタル波形に変換し演算制御部132に入力する。演算制御部132内部でこのデジタル波形を一定周期で読込み、活動パルスが検出された回数を計数する。所定時間の間の検出回数が、人有りとする在閾値以上の時に、例えば位置Q,Rに人が居る時に、演算制御部132は左人検知センサ140aが人を検知した判断する。同様に赤外線センサ410c,右人検知センサ140cも図22(c),(d)のように信号を出力し、同様に、例えば位置R,Sに人が居る時に、演算制御部132は右人検知センサ140cが人を検知した判断する。   As shown in FIG. 21, when a person 907 enters the room 902 from the position P and moves to the position S through the positions Q and R, the infrared sensor 410a of the infrared detecting device 14 is analog as shown in FIG. Output a signal. When the absolute value of the analog output exceeds a certain level, this analog output is processed by the amplifier 130, the comparator 131, etc. so as to output an activity pulse (Hi pulse in the embodiment), and FIG. Is converted into a digital waveform as shown in FIG. The digital waveform is read at a constant cycle inside the arithmetic control unit 132, and the number of times that an activity pulse is detected is counted. When the number of detections during a predetermined time is equal to or greater than the presence threshold value indicating that there is a person, for example, when there is a person at positions Q and R, the arithmetic control unit 132 determines that the left person detection sensor 140a has detected a person. Similarly, the infrared sensor 410c and the right person detection sensor 140c also output signals as shown in FIGS. 22C and 22D. Similarly, when there is a person at the positions R and S, for example, the arithmetic control unit 132 sets the right person. It is determined that the detection sensor 140c has detected a person.

上記の説明では、説明を簡潔にするため、あたかも、人が移動する瞬間毎に人有りの判断が下されるように書いたが、実施例では所定時間を30秒にしてあるので、入室と移動の間のほんの数秒の反応だけでは人有りの判断は下されなく、人が移動をやめてからの自然な動きを感知しての反応が大勢を決することになる。このように、所定時間を適切に選ぶことにより、単に通過するだけの時に、人有りと判断し、不要な制御をする恐れを大幅に減らすことができる。また、赤外線センサ410を2個使用することで、検知区域を左人検知センサ140aだけが検知する領域、右人検知センサ140cだけが検知する領域、左右の人検知センサ140a,cが検知する領域の3つに区分することができる。   In the above description, for the sake of brevity, it is written as if there is a person at every moment when a person moves. However, in the embodiment, the predetermined time is set to 30 seconds. A response of just a few seconds between movements does not make a decision about the presence of a person, but the reaction of sensing the natural movement after a person stops moving will determine the majority. As described above, by appropriately selecting the predetermined time, it is possible to significantly reduce the possibility of performing the unnecessary control by determining that there is a person when the vehicle simply passes. Further, by using two infrared sensors 410, a detection area is detected only by the left person detection sensor 140a, an area detected by the right person detection sensor 140c, and an area detected by the left and right human detection sensors 140a, c. It can be divided into three.

なお、実施例では活動パルスをHiパルスにしているが、逆に、室内に人が不在の時の人検知センサ140の出力をHiにし、人が活動したときの出力をLoにして、Loの活動パルスの検出回数を計数するようにしても良いのは勿論のことである。   In the embodiment, the activity pulse is Hi pulse, but conversely, the output of the human detection sensor 140 when no person is present in the room is Hi, the output when the person is active is Lo, and Lo Of course, the number of detections of the activity pulse may be counted.

赤外線検知装置14を室内機2に取り付け、この検知区域を簡単のため、床面の高さまで下げて図23のように表し、上述のように室内を左右の人検知センサ140a,cが単独で検知する検知領域610A,C,左右の人検知センサ140a,cが重複して検知する検知領域610ACに区分する。なお、説明を簡略にするため領域610Aを(1)、領域610Cを(2)、領域610ACを(3)と略記する場合もある。   The infrared detector 14 is attached to the indoor unit 2 and this detection area is lowered to the level of the floor surface for the sake of simplicity, and is represented as shown in FIG. 23. As described above, the left and right human detection sensors 140a and 140c are independent. The detection areas 610A and C for detection and the left and right human detection sensors 140a and 140c are divided into detection areas 610AC for detection. In order to simplify the description, the region 610A may be abbreviated as (1), the region 610C may be abbreviated as (2), and the region 610AC may be abbreviated as (3).

左人検知センサ140aのみが検知した場合は、検知領域610Aに人体が存在し、右人検知センサ140cのみが検知した場合は、検知領域610Cに人体が存在し、左人検知センサ140aと右人検知センサ140cの両方が検知した場合は、検知領域610AC又は検知領域610Aと検知領域610Cに人体が存在していると推定する。   When only the left person detection sensor 140a detects, a human body exists in the detection area 610A, and when only the right person detection sensor 140c detects, a human body exists in the detection area 610C, and the left person detection sensor 140a and the right person When both detection sensors 140c detect, it is estimated that a human body exists in detection area 610AC or detection area 610A and detection area 610C.

ここで、領域の構成について図24を用いて説明する。図24は領域の説明図、(a)はAとCの和の領域、(b)はAとCの排他和の領域、(c)はAからCを除外した差の領域、(d)はCからAを除外した差の領域、(e)はAとCの積の領域である。   Here, the configuration of the region will be described with reference to FIG. FIG. 24 is an explanatory diagram of the area, (a) is the area of the sum of A and C, (b) is the area of the exclusive sum of A and C, (c) is the area of the difference excluding C from A, (d) Is a difference area excluding A from C, and (e) is a product area of A and C.

実施例では人検知センサ140の出力から人が居ると推定する領域を、左右の人検知センサ140a,cの検知区域の和、排他和、差、又は積で構成する。図24(a)のように左人検知センサ140aの検知区域Aを記号Aで、右人検知センサ140cの検知区域Cを記号Cで示すとき、区域Aと区域Cの和を図24(a)の斜線部、区域Aと区域Cの排他和を図24(b)の斜線部、区域Aと区域Cの差を図24(c)の斜線部、区域Cと区域Aの差を図24(d)の斜線部、区域Aと区域Cの積を図24(e)の斜線部と定義する。このような定義は群論から容易に類推でき、理解しやすい。   In the embodiment, the region estimated to be a person from the output of the human detection sensor 140 is configured by the sum, exclusive sum, difference, or product of the detection areas of the left and right human detection sensors 140a and 140c. When the detection area A of the left person detection sensor 140a is indicated by symbol A and the detection area C of the right person detection sensor 140c is indicated by symbol C as shown in FIG. 24A, the sum of the area A and the area C is shown in FIG. 24), the exclusive sum of area A and area C is the hatched area in FIG. 24 (b), the difference between area A and area C is the hatched area in FIG. 24 (c), and the difference between area C and area A is FIG. The hatched portion in (d), the product of the sections A and C, is defined as the hatched portion in FIG. Such a definition can be easily inferred from group theory and is easy to understand.

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25〜図28を用いて説明する。図25は上下風向板で検知領域を区分する説明図である。図26は上下風向板による遠領域検知状態図である。図27は上下風向板による中領域検知状態図である。図28は上下風向板による近領域検知状態図である。   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. 25 is an explanatory diagram that divides the detection region by the vertical wind direction plate. FIG. 26 is a far area detection state diagram by the vertical wind direction plate. FIG. 27 is a state detection state diagram of the middle region by the vertical wind direction plate. FIG. 28 is a near-region detection state diagram by the up and down wind direction plates.

実施例では、前述の空気調和機の左右方向の室内の検知領域の区分に加えて、空気調和機の奥行き方向の室内についても上下風向板291を用いて検知領域を区分する。上側上下風向板291は前述のように、吹出し風路290の下流に設けた、上方に拡大する上方拡大部290eに吹出し気流を導く作用を有している。在室者の有無を検知するときに、この上側上下風向板291を、赤外線センサ410の視野を部分的に遮るような位置に回動させて停める。上側上下風向板291を停止させる位置は図25に示すごとく、上側上下風向板291の図象の先端に付けた符号i,j,k,mの位置でこれらの位置を夫々上側上下風向板位置491i,j,k,mのごとくに呼ぶ。   In the embodiment, in addition to the above-described division of the detection area in the left-right room of the air conditioner, the detection area is also divided using the up / down wind direction plate 291 in the depth direction of the air conditioner. As described above, the upper vertical wind direction plate 291 has a function of guiding the blown airflow to the upper enlarged portion 290e that is provided downstream of the blowout air passage 290 and expands upward. When detecting the presence or absence of an occupant, the upper vertical wind direction plate 291 is rotated and stopped at a position that partially blocks the visual field of the infrared sensor 410. As shown in FIG. 25, the upper and lower wind direction plates 291 are stopped at positions i, j, k, and m attached to the tips of the upper upper and lower wind direction plates 291 respectively. They are called 491i, j, k, m.

上側上下風向板位置491iでは赤外線センサ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では赤外線センサ410の視野のうち、検知範囲591jのみが検知可能であり、上側上下風向板位置491kでは検知範囲591kのみが検知可能となる。上側上下風向板位置491mでは検知範囲591m=全視野が検知可能となる。   At the upper vertical wind direction plate position 491i, the entire field of view of the infrared sensor 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. Of the visual field of the infrared sensor 410, only the detection range 591j can be detected at the upper vertical wind direction plate position 491j, and only the detection range 591k can be detected at the upper vertical wind direction plate position 491k. At the upper vertical wind direction plate position 491m, the detection range 591m = 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しようとする場合は、まず、図26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、赤外線センサ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に居ることが判る。   In order to detect the position of the 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. Detect the presence or absence of a room person. If the occupant is detected at this time, it is understood that the occupant is in the detection range 591j.

次に、図27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、赤外線センサ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に居ることが判る。更に、先の検知動作で検知範囲591jに人が検知されなかった場合は検知範囲591kから検知範囲591jを除外した範囲に人が居ると判る。   Next, as shown in FIG. 27, 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 sensor 410. If the occupant is detected at this time, it is understood that the occupant is in the detection range 591k including the detection range 591j. Furthermore, when no person is detected in the detection range 591j in the previous detection operation, it is determined that there is a person in the range excluding the detection range 591j from the detection range 591k.

次に、図28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、赤外線センサ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に居ることが判る。更に、先の検知動作で検知範囲591kに人が検知されなかった場合は検知範囲591mから検知範囲591kを除外した範囲に人が居ると判る。   Next, as shown in FIG. 28, 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 sensor 410. If the occupant is detected at this time, it is understood that the occupant is in the detection range 591m including the detection range 591k. Further, if no person is detected in the detection range 591k in the previous detection operation, it is understood that there is a person in the range excluding the detection range 591k from the detection range 591m.

次に、赤外線センサ410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29〜図31を用いて説明する。図29は上下風向板による遠近方向の検知領域区分図である。図30は上下風向板による床面の検知領域区分図である。図31は左右の赤外線センサと上下風向板による検知領域区分図である。   Next, a method for estimating the presence area in the depth direction from the presence or absence of a resident detected by the infrared sensor 410 will be described with reference to FIGS. 29 to 31. FIG. 29 is a detection area division diagram in the perspective direction by the up and down wind direction plates. FIG. 30 is a detection area division diagram of the floor surface by the vertical wind direction plate. FIG. 31 is a detection area division diagram by the left and right infrared sensors and the vertical wind direction plate.

上述の3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29のように、上側上下風向板291を上側上下風向板位置491jで停止させて在室者の有無を検知する場合は、赤外線センサ410の視野が検知範囲591jに限られるので、検知領域691Jの在室者を検知することになる。   When the results obtained by the above-described three detection operations are made to correspond to the depth direction of the room as viewed from the air conditioner, the upper vertical wind direction plate 291 is stopped at the upper vertical wind direction plate position 491j as shown in FIG. In the case where the presence / absence of an occupant is detected, the field of view of the infrared sensor 410 is limited to the detection range 591j, and therefore the occupant in the detection area 691J is detected.

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、赤外線センサ410の視野が検知範囲591kに広がるので、検知領域691J,Kの在室者を検知することになる。   Further, when detecting the presence or absence of an occupant by stopping the upper vertical wind direction plate 291 at the upper vertical wind direction plate position 491k, the field of view of the infrared sensor 410 extends to the detection range 591k. Will be detected.

更に、上側上下風向板291を上側上下風向板位置491mで停止させて在室者の有無を検知する場合は、赤外線センサ410の視野がまったく遮られず、検知範囲591mに広がるので、全ての検知領域691J,K,Mの在室者を検知することになる。   Further, when detecting the presence or 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 sensor 410 is not obstructed at all and extends to the detection range 591m. A person in the area 691J, K, M is detected.

上記の検知領域を床面での広がりで見ると図30のようになり、室内の奥行き方向に検知領域を区分することができる。   When the above detection area is viewed as being spread on the floor, it is as shown in FIG. 30, and the detection area can be divided in the depth direction of the room.

このように、前述の図8に示した複数の赤外線センサ410a,cを用いて室内を図23のように左右方向に区分し、上側上下風向板291を用いて室内を前後方向に区分することにより、図31に示すように室内を前後左右に交差検知エリア710JA〜MCの9領域に区分し、在室者の居る方向とその奥行き範囲を知ることができ、これを用いて、空気調和機を適切に制御することができる。   As described above, the plurality of infrared sensors 410a and 410c shown in FIG. 8 are used to divide the room in the left-right direction as shown in FIG. 23, and the upper vertical wind direction plate 291 is used to divide the room in the front-rear direction. As shown in FIG. 31, the room is divided into nine areas of intersection detection areas 710JA to MC in the front, rear, left and right directions, and the direction in which the occupants are present and the depth range thereof can be known. Can be controlled appropriately.

なお、上述の説明では説明を簡単にするため、検知領域の境界を検知範囲の境界が床面に達する位置に置いたが、実際に、赤外線センサ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、検知領域の境界線は厳密には求められない。しかし、大まかには人が室内の遠いところに居る、中位のところに居る、近くに居る、のような区分けは十分可能であり、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持つことができる。   In the above description, for the sake of simplicity, the boundary of the detection region is placed at a position where the boundary of the detection range reaches the floor surface. However, the position of the human face and neck that are easily detected by the infrared sensor 410 actually. Depending on whether the person is standing, sitting on a chair, sitting on the floor, sleeping, etc., the boundary line of the detection area cannot be strictly determined. However, it is possible to roughly classify people such as being far away in the room, being in the middle, or being close to the room. Therefore, the air conditioning according to the classification as described above can have a sufficient effect.

このように、実施例の赤外線検知装置を有する空気調和機は、1対の赤外線センサと、1対のフレネルレンズと、前記赤外線センサを固定する1対の台座を搭載した基板を備え、

一般に、家庭用の室内機は横型の壁掛け型が多いので、以下の説明は簡単のため、横型の室内機に左右対称に1対の赤外線検知装置を設けた例について説明する。   In general, since many indoor indoor units are horizontal wall-mounted units, for the sake of simplicity, an example in which a pair of infrared detectors are provided symmetrically on a horizontal indoor unit will be described.

実施例の赤外線検知装置を有する空気調和機によれば、赤外線センサを異なる方向に向けて搭載するので左右2個の赤外線センサで室内を大きく3つの領域に分けることができ、人の居る部分に向けて自動的に空調空気を選択的に送るとか、送らないとかの制御ができ、煩わしい操作をすることなしに在室者の快適性を維持しつつ、省エネ運転するなどの利便性や満足度が高く、地球環境にも優しい空気調和運転ができる。このように、利便性が高く、快適性を維持しつつ、省エネ運転ができる空気調和機が得られる。   According to the air conditioner having the infrared detection device of the embodiment, since the infrared sensor is mounted in different directions, the room can be roughly divided into three regions by two infrared sensors on the left and right sides. Convenience and satisfaction such as energy-saving operation while maintaining the comfort of occupants without the need for troublesome operations.

また、赤外線センサ,フレネルレンズ,台座,基板を一体にできるので製造時やサービス時の取扱いが簡便になり、ミスを防ぐことができる。   In addition, since the infrared sensor, Fresnel lens, pedestal, and substrate can be integrated, handling at the time of manufacture and service becomes simple, and mistakes can be prevented.

このため、部品を共用して生産コストを節減できる赤外線検知装置を有する空気調和機を提供することができる。   For this reason, the air conditioner which has an infrared rays detection device which can reduce production cost by sharing components can be provided.

これにより、例えば、特定な領域に日射が当ったり、加熱器のオンオフがあった時には一時的に検知出力は増加するが、赤外線センサが焦電型のため、じきに、背景温度と捉えられるようになって、検知され無くなって、誤って人有りと判断されることは無い。   As a result, for example, when a specific area is exposed to sunlight or the heater is turned on / off, the detection output temporarily increases. However, since the infrared sensor is a pyroelectric type, it will soon be recognized as the background temperature. Therefore, it will not be detected and it will not be mistakenly determined that there is a person.

また、台座の中心軸と基板とを所定の角度で交差させることで、室内を適切な範囲に区分して人の在否を検知でき、調整の必要が無い。   In addition, by crossing the center axis of the pedestal and the substrate at a predetermined angle, it is possible to detect the presence or absence of a person by dividing the room into an appropriate range, and there is no need for adjustment.

また、赤外線センサ,台座,フレネルレンズ,基板を組立てる時に互いの取付部,係着部,位置決め部,信号線貫通部が適切に配置されていて、組立てに迷うことが無く、誤組立ても防ぐことができる。   In addition, when assembling the infrared sensor, pedestal, Fresnel lens, and board, each other's mounting part, engaging part, positioning part and signal line penetration part are properly arranged, so there is no hesitation in assembling and preventing misassembly.

A plurality of signal lines extending from positions asymmetric with respect to a plane orthogonal to the central axis perpendicular to the central axis of the axial plane, and when the pedestal is mounted on the substrate surface, the central axis is at a predetermined angle with the substrate surface (60 degrees in the embodiment) formed so as to intersect with each other, the engaging portion symmetrical to the central axis plane and the central axis orthogonal plane for engaging the Fresnel lens, an infrared sensor mounting portion, and the infrared ray Sensor signal line penetrates A plurality of through holes provided at positions symmetrical to a central axis plane and a central axis orthogonal plane, and a plurality of positioning projections provided on a mounting surface of the substrate; A positioning hole through which the positioning protrusion penetrates and a central orthogonal plane that is asymmetric with respect to the line of intersection between the central axis orthogonal plane and the substrate and perpendicular to the central axis plane that intersects the bisecting straight line. A plurality of through holes through which the signal line of the infrared sensor that is asymmetrical passes, and the division of the lens portion of the Fresnel lens is asymmetric with respect to the central axis plane and symmetrical with respect to the central axis orthogonal plane Yes, a locking leg symmetrical with respect to the central axis plane and the central axis orthogonal plane engaged with the pedestal, and a misassembly prevention portion symmetrical with respect to the central axis orthogonal plane and asymmetric with respect to the central axis plane It is configured as follows.

このように、実施例の赤外線検知装置を有する空気調和機は、前記赤外線センサの信号線は中心軸に4回対称の位置の3ヶ所に配置され、前記台座は上記赤外線センサの前記取付部は中心軸に2回対称の形状に形成され、前記フレネルレンズの前記係着部は中心軸に2回対称の形状に形成され、上記赤外線センサの上記信号線が貫通するための少なくとも3個以上の前記貫通孔を、中心軸に2回対称の位置に有し、前記基板は台座搭載面が両中心軸が成す角を2等分する直線に垂直に設けられ、前記2組の複数の位置決め孔は、上記2等分する直線に2回対称に配置され、前記3個の貫通孔の2組は、両中心軸と台座搭載面の交点間の距離だけ、平行移動した位置に配置され、上記フレネルレンズは2本の中心軸を含む中心軸平面に非対称に形成され、分割された小フレネルレンズ群を有し、前記係着脚は中心軸に2回対称に形成され、前記誤組立て防止部は、中心軸で上記中心軸平面に交わる中心軸直交平面に対称で、且つ、上記中心軸平面に対して非対称に配置されている。   Thus, in the air conditioner having the infrared detection device of the embodiment, the signal line of the infrared sensor is arranged at three positions that are four times symmetrical with respect to the central axis, and the pedestal has the mounting portion of the infrared sensor. The engaging portion of the Fresnel lens is formed in a two-fold symmetrical shape with respect to the central axis, and at least three or more of the signal lines of the infrared sensor penetrate therethrough. The through hole is provided at a position twice symmetrical with respect to the central axis, and the base mounting surface is provided perpendicular to a straight line that bisects the angle formed by both central axes, and the two sets of the plurality of positioning holes Are arranged symmetrically twice with respect to the bisecting straight line, and the two sets of the three through holes are arranged at a position translated by the distance between the intersections of the central axes and the pedestal mounting surface, The Fresnel lens is asymmetrical on a central axis plane that includes two central axes. A small Fresnel lens group formed and divided, wherein the engaging legs are formed symmetrically with respect to a central axis, and the misassembly prevention portion is formed on a central axis orthogonal plane intersecting the central axis plane with the central axis. They are arranged symmetrically and asymmetrically with respect to the central axis plane.

これにより、台座は左右非対称、上下対称に形成され、赤外線センサの信号線の取出し部は上下左右非対称になる。   As a result, the pedestal is formed asymmetrical in the left-right direction and symmetrical in the vertical direction, and the signal line take-out portion of the infrared sensor is asymmetrical in the vertical and horizontal directions.

フレネルレンズは検知範囲をできるだけ一様に検知できるよう、下側は粗く、上側は細かく分割され、上下は非対称、左右は対称に形成され、台座との係着部の見やすいところに誤組立てを注意する突起が設けられる。   In order to detect the detection range as uniformly as possible, the Fresnel lens is roughly divided on the lower side, finely divided on the upper side, asymmetrical on the top and bottom, and symmetrically on the left and right. Protrusions are provided.

更に、基板は左右の台座の位置決め孔が中央直交平面に対して対称に、更に、赤外線センサの信号線の貫通孔が平行移動の位置に孔設される。このようにすることで、台座を左右反転させて基板に取り付け、左右の赤外線検知装置に同一のフレネルレンズ,台座,赤外線センサを使用でき、部品のコストが低減される。   Further, in the substrate, the positioning holes of the left and right pedestals are symmetrical with respect to the central orthogonal plane, and further, the through holes of the signal lines of the infrared sensor are provided at the positions of parallel movement. By doing so, the pedestal can be reversed and attached to the substrate, and the same Fresnel lens, pedestal, and infrared sensor can be used for the left and right infrared detection devices, thereby reducing the cost of components.

更にまた、基板に台座を装着するときは、赤外線センサの中心軸方向に台座の向きをあわせて取り付ける。このとき、台座の取付姿勢は明らかに違うので、台座の取付方向を誤る恐れは非常に小さい。次に赤外線センサの信号線を台座の複数の貫通孔に挿入する。このとき、台座が載っている基板には正しい信号線の配置に応じた位置にしか貫通孔が開いていないので、赤外線センサが誤った姿勢に取り付けられることは無い。   Furthermore, when the pedestal is mounted on the substrate, the pedestal is attached in the direction of the central axis of the infrared sensor. At this time, since the mounting orientation of the pedestal is clearly different, there is very little risk of erroneous mounting direction of the pedestal. Next, the signal line of the infrared sensor is inserted into the plurality of through holes of the base. At this time, since the through hole is opened only at a position corresponding to the correct arrangement of the signal line on the board on which the pedestal is placed, the infrared sensor is not attached in a wrong posture.

次に、フレネルレンズをかぶせる時には、フレネルレンズの見やすい位置に設けた誤組立て防止突起を見てその位置を確認しながら、フレネルレンズを台座に取り付けるので、ここでも誤ってフレネルレンズを180度回転させた誤った姿勢で組立てる恐れは極めて小さい。   Next, when the Fresnel lens is put on, the Fresnel lens is attached to the pedestal while checking the position of the Fresnel lens at the easy-to-see position so that the Fresnel lens can be rotated. The risk of assembly in the wrong posture is very small.

このため、左右のフレネルレンズ,台座,赤外線センサを共用して、赤外線センサ信号線の非対称配置とフレネルレンズの誤組立て防止突起で誤組立てを防ぎ、品質が一様で、信頼性が高く、赤外線生産コストも節減できる赤外線検知装置を有する空気調和機を提供することができる。   For this reason, the right and left Fresnel lenses, pedestal, and infrared sensor are shared, and the asymmetrical arrangement of the infrared sensor signal lines and the Fresnel lens misassembly prevention protrusions prevent misassembly, uniform quality, high reliability, and infrared It is possible to provide an air conditioner having an infrared detector that can reduce production costs.

また基板416の左右の楕円状の装着部416−7a,cに各2個の位置決め孔416−1a,416−1′a及び416−1c,416−1′cが設けられていて、片方の位置決め孔416−1a,416−1cは長軸(装着部水平線)416−9上に、他方の位置決め孔416−1′a,416−1′cは装着部水平線416−9及び短軸(装着部垂直線)416−10a,416−10cから外れた台座415の他方の位置決め突起415−1′a,415−1′cの位置に対応した位置に設けてある。   In addition, two positioning holes 416-1a, 416-1'a and 416-1c, 416-1'c are provided in the left and right elliptical mounting portions 416-7a, c of the substrate 416, respectively. The positioning holes 416-1a and 416-1c are on the long axis (mounting part horizontal line) 416-9, and the other positioning holes 416-1'a and 416-1'c are the mounting part horizontal line 416-9 and the short axis (mounting). (Part vertical line) 416-10a, 416-10c is provided at a position corresponding to the position of the other positioning protrusions 415-1'a, 415-1'c of the base 415.

このように、実施例2の空気調和機は、前記台座の前記複数の位置決め突起は前記基板との前記装着面に設けられ、該複数の位置決め突起の位置は、該複数の位置決め突起を、前記中心軸と装着面との交点から立てた該装着面に垂直な軸の周りに回転移動させたときに、どの回転位置でも合致しないように配置され、前記基板の複数の位置決め孔の位置は、該複数の位置決め孔を、前記中心軸と台座搭載面との交点から立てた該基板に垂直な軸の周りに回転移動させたときに、どの回転位置でも合致しないように配置され、且つ、前記装置中央軸に対して2回対称の位置に、各々該複数の位置決め孔を備える如く構成される。   Thus, in the air conditioner of Example 2, the plurality of positioning protrusions of the pedestal are provided on the mounting surface with the substrate, and the positions of the plurality of positioning protrusions are the positions of the plurality of positioning protrusions, When rotating around an axis perpendicular to the mounting surface established from the intersection of the central axis and the mounting surface, it is arranged so that it does not match at any rotational position, and the positions of the plurality of positioning holes in the substrate are: When the plurality of positioning holes are rotated around an axis perpendicular to the substrate set up from the intersection of the central axis and the pedestal mounting surface, the plurality of positioning holes are arranged so as not to coincide at any rotational position, and Each of the plurality of positioning holes is provided at a position twice symmetrical with respect to the central axis of the apparatus.

また、実施例2の空気調和機は、前記台座の前記複数の位置決め突起は、前記基板との装着面に設けた前記中心軸平面に対して非対称、且つ前記中心軸直交平面と該装着面との交線に対して非対称、且つ中心軸と装着面の交点から立てた装着面からの垂線に対して非回転対称に形成される如く構成される。   Further, in the air conditioner of Example 2, the plurality of positioning protrusions of the pedestal are asymmetric with respect to the central axis plane provided on the mounting surface with the substrate, and the central axis orthogonal plane and the mounting surface It is configured so as to be asymmetric with respect to the intersecting line and non-rotationally symmetric with respect to a perpendicular from the mounting surface set up from the intersection of the central axis and the mounting surface.

また、基板には左右の台座の位置決め孔が装置中央軸に2回対称に、更に、赤外線センサの信号線の貫通孔が平行移動の位置に孔設される。このようにすることで、左右の赤外線検知装置に同一のフレネルレンズ,台座,赤外線センサを使用でき、部品のコストが低減される。   Further, the left and right pedestal positioning holes are provided twice symmetrically with respect to the central axis of the apparatus, and the signal line through hole of the infrared sensor is provided at the position of parallel movement in the substrate. By doing so, the same Fresnel lens, pedestal, and infrared sensor can be used for the left and right infrared detectors, and the cost of the components is reduced.

実施例3ではフレネルレンズ417にある誤組立て防止部417−2,417−2′を胴体417−3から後方に同じ長さだけ延ばして係着脚417−5よりも突出させる。具体的には基板416に装着した台座415に係着したときに基板416に近い側の誤組立て防止部417−2の先端が基板416を突き抜け、基板416に遠い側の誤組立て防止部417−2′の先端が基板416に達しない長さにする。   In the third embodiment, the misassembly prevention portions 417-2 and 417-2 'in the Fresnel lens 417 are extended rearward from the body 417-3 by the same length and protruded from the engaging leg 417-5. Specifically, the tip of the misassembly prevention unit 417-2 on the side close to the substrate 416 penetrates the substrate 416 when engaged with the base 415 attached to the substrate 416, and the misassembly prevention unit 417- on the side far from the substrate 416 The length of the 2 ′ tip does not reach the substrate 416.

また、基板416に台座415、フレネルレンズ417を正しく取り付けたときに、誤組立て防止部417−2,417−2′が基板416を突き抜ける位置に、レンズ誤組立て防止孔416−2a,416−2cを設ける。   Further, when the pedestal 415 and the Fresnel lens 417 are correctly attached to the substrate 416, the lens misassembly prevention holes 416-2a and 416-2c are formed at positions where the misassembly prevention portions 417-2 and 417-2 ′ penetrate the substrate 416. Is provided.

このように、実施例3の空気調和機は、前記基板の、前記フレネルレンズに設けた誤組立て防止部が貫入する誤組立て防止孔は、前記中央直交平面に対して対称な位置に設けられ、該フレネルレンズの該誤組立て防止部の長さは、該フレネルレンズを前記台座を介して前記基板に取り付けたときに、該基板に近い側の該誤組立て防止部が該基板の誤組立て防止孔に貫入し、これと前記中心軸直交平面に対して対称な位置に有る、該基板に遠い側の該誤組立て防止部が該基板に達しない長さに形成されている如く構成される。   Thus, in the air conditioner of Example 3, the misassembly prevention hole through which the misassembly prevention portion provided in the Fresnel lens of the substrate penetrates is provided at a symmetrical position with respect to the central orthogonal plane, The length of the misassembly prevention portion of the Fresnel lens is such that when the Fresnel lens is attached to the substrate via the pedestal, the misassembly prevention portion on the side close to the substrate is the misassembly prevention hole of the substrate. The misassembly prevention portion on the side far from the substrate and symmetric with respect to the plane orthogonal to the central axis is formed to have a length that does not reach the substrate.

また、実施例3の空気調和機は、前記基板が、該中央直交平面に対して対称な、フレネルレンズに設けた誤組立て防止部が貫入する誤組立て防止孔とを有し、該フレネルレンズの該誤組立て防止部が該フレネルレンズを台座を介して前記基板に取り付けたときに、基板に近い側の該誤組立て防止部が基板の誤組立て防止孔に貫入し、これと中心軸直交平面に対して対称な位置に有る、基板に遠い側の誤組立て防止部は該基板に達しない長さを有している如く構成される。   Further, in the air conditioner of Example 3, the substrate has a misassembly prevention hole which is symmetric with respect to the central orthogonal plane and through which a misassembly prevention portion provided in the Fresnel lens penetrates. When the misassembly prevention unit attaches the Fresnel lens to the substrate via a pedestal, the misassembly prevention unit on the side close to the substrate penetrates into the misassembly prevention hole of the substrate and is in a plane perpendicular to the central axis. On the other hand, the misassembly prevention portion on the side far from the substrate at a symmetrical position is configured to have a length that does not reach the substrate.

このように、実施例の赤外線検知装置を有する空気調和機は、前記基板に、前記フレネルレンズに設けた前記誤組立て防止部が貫入する誤組立て防止孔を有し、上記誤組立て防止孔は、前記2等分する直線で交わる前記中心軸平面に垂直な中央直交平面に面対称で、且つ、前記中心軸平面に非対称な位置に設けられ、上記フレネルレンズの上記誤組立て防止部の長さは、上記フレネルレンズを前記台座を介して上記基板に取り付けたときに、上記基板に近い側の上記誤組立て防止部が上記基板の上記誤組立て防止孔に貫入し、上記基板に遠い側の上記誤組立て防止部が上記基板に達しない長さに形成されている。   As described above, the air conditioner having the infrared detection device of the embodiment has a misassembly prevention hole through which the misassembly prevention portion provided in the Fresnel lens penetrates the substrate, and the misassembly prevention hole is The length of the misassembly prevention portion of the Fresnel lens is provided at a position symmetrical with respect to a central orthogonal plane perpendicular to the central axis plane intersecting with the bisecting straight line and asymmetric with respect to the central axis plane. When the Fresnel lens is attached to the substrate via the pedestal, the misassembly prevention portion on the side close to the substrate penetrates into the misassembly prevention hole of the substrate and the error on the side far from the substrate. The assembly preventing portion is formed to a length that does not reach the substrate.

これにより、フレネルレンズの誤組立て防止突起の片側が基板まで達する長さに形成される。   Thus, the Fresnel lens is formed in such a length that one side of the misassembly prevention protrusion reaches the substrate.

また、基板には中央直交平面に対して対称に誤組立て防止孔が孔設される。このようにすることで、左右の赤外線検知装置に同一のフレネルレンズ,台座,赤外線センサを使用でき、部品のコストが低減される。   The substrate is provided with a misassembly prevention hole symmetrically with respect to the central orthogonal plane. By doing so, the same Fresnel lens, pedestal, and infrared sensor can be used for the left and right infrared detectors, and the cost of the components is reduced.

また、基板に装着した台座にフレネルレンズをかぶせる時には、フレネルレンズを正しく取り付けた時には前記誤組立て防止部が該基板の誤組立て防止孔に貫入し、フレネルレンズの取り付けが妨げられることは無い。しかし、フレネルレンズを180度回転させた正しくない姿勢に取り付けようとすると前記誤組立て防止部が基板にぶつかり、フレネルレンズの取り付けが妨げられる。このように、フレネルレンズの誤組立てが防止される。   Further, when the Fresnel lens is put on the pedestal mounted on the substrate, when the Fresnel lens is correctly attached, the misassembly prevention portion penetrates into the misassembly prevention hole of the substrate, and the attachment of the Fresnel lens is not hindered. However, if the Fresnel lens is to be mounted in an incorrect posture rotated by 180 degrees, the misassembly prevention unit hits the substrate, and the mounting of the Fresnel lens is hindered. In this way, incorrect assembly of the Fresnel lens is prevented.

このため、更にレンズの基板への誤組立ても防止できる赤外線検知装置を有する空気調和機を提供することができる。   For this reason, the air conditioner which has the infrared rays detection apparatus which can prevent also the incorrect assembly to the board | substrate of a lens can be provided.

これまでは、赤外線センサの中心軸が交わる例で説明してきたが、実施例4では赤外線センサの中心軸が交わるない例について図39〜図42を用いて説明する。図39は実施例4の赤外線検知装置の斜視図である。図40は検知装置の中心軸平行平面の説明図である。図41は検知装置の中心軸直交平面の説明図である。図42は検知装置の中央直交平面の説明図である。   So far, the example in which the central axes of the infrared sensors intersect has been described. In Example 4, an example in which the central axes of the infrared sensors do not intersect will be described with reference to FIGS. FIG. 39 is a perspective view of the infrared detecting device according to the fourth embodiment. FIG. 40 is an explanatory diagram of a central axis parallel plane of the detection device. FIG. 41 is an explanatory diagram of a plane orthogonal to the central axis of the detection device. FIG. 42 is an explanatory diagram of a central orthogonal plane of the detection device.

これまでの実施例では、両中心軸が交わるようにしたが、本発明はこれに限定されるものではなく、両中心軸間の距離が部屋の大きさに比べて無視できる程度の距離であれば、適用できる。空気調和機に使用する場合、何を制御するかによってこの距離は違ってくるが30cm以下であれば通常の制御には支障は無い。   In the embodiments so far, both the central axes intersect, but the present invention is not limited to this, and the distance between the two central axes can be negligible compared to the size of the room. If applicable. When used in an air conditioner, this distance varies depending on what is controlled, but there is no hindrance to normal control if it is 30 cm or less.

この場合、実施例中の「両中心軸が成す角を2等分する直線」は図39の「両中心軸412a,cを最短距離で結ぶ線分401−2の中点401−1(=中心軸仮想交点)から引いた両中心軸に平行な直線412a′,412c′が成す角を2等分する直線=装置中央軸402」と読み替える。   In this case, the “straight line that bisects the angle formed by the two central axes” in the embodiment is “the midpoint 401-1 of the line segment 401-2 that connects the two central axes 412a and 4c with the shortest distance” (= The straight line that bisects the angle formed by the straight lines 412a 'and 412c' parallel to both the central axes drawn from the virtual center intersection of the central axes) = "device central axis 402".

また、「中心軸平面」は図40の「1方の中心軸412a,cを含み、他方の中心軸412c,aに平行な中心軸平行平面421a,421c」と読み替える。   Further, the “center axis plane” is read as “center axis parallel planes 421a, 421c including one center axis 412a, c and parallel to the other center axis 412c, a” in FIG.

また、「中心軸直交平面」は図41の「中心軸412a,cで中心軸平行平面421a,cに交わる中心軸直交平面422a,c」と読み替える。   Further, the “center axis orthogonal plane” is read as “center axis orthogonal planes 422a, c intersecting the center axis parallel planes 421a, c at the center axes 412a, c” in FIG.

また、「両中心軸が成す角を2等分する直線で交わる中心軸平面に垂直な中央直交平面」は図42の「両中心軸412a,cを最短距離で結ぶ線分401−1の中点401から引いた両中心軸412a,cに平行な直線412a′,c′が成す角を2等分する直線402で交わる中心軸平行平面421a,421cに垂直な中央直交平面423」と読み替えることで同様の効果をもたらす構成とすることができる。   Further, “a central orthogonal plane perpendicular to the central axis plane intersecting with a straight line that bisects the angle formed by the two central axes” is “in the line segment 401-1 connecting both the central axes 412a and 4c with the shortest distance” in FIG. The center orthogonal plane 423 perpendicular to the central axis parallel planes 421a and 421c intersected by the straight line 402 that bisects the angle formed by the straight lines 412a 'and c' parallel to both the central axes 412a and c 'drawn from the point 401 It can be set as the structure which brings about the same effect.

次に、本発明の異なった形状の空気調和機への適用について図43を用いて説明する。図43は縦型空気調和機概略図である。   Next, application of the present invention to an air conditioner having a different shape will be described with reference to FIG. FIG. 43 is a schematic view of a vertical air conditioner.

上記実施例の説明は、横流ファンを使用した壁掛形の空気調和機を例にとったが、本発明はこれに限定されるものではなく、左右風向板,上下風向板を備えた空気調和機であれば、送風ファンは横流ファンに限らずターボファン,シロッコファン,プロペラファンなどでも良く、形態も壁掛け型に限るものではない。すなわち、天井据付型,床置き型,窓据付型等の形態に拘らず適用できるものであり、左右風向板,上下風向板のいずれか又は両方で赤外線センサの視野を部分的に遮蔽して、人検知動作を行うことで在室者の有無と在室者の位置を推定することができる。   In the description of the above embodiment, a wall-hanging air conditioner using a cross-flow fan is taken as an example. However, the present invention is not limited to this, and an air conditioner provided with left and right wind direction plates and up and down wind direction plates. If so, the blower fan is not limited to a cross-flow fan but may be a turbo fan, a sirocco fan, a propeller fan, or the like, and the form is not limited to a wall-mounted type. That is, it can be applied regardless of the ceiling-mounted type, floor-mounted type, window-mounted type, etc., and partially shields the field of view of the infrared sensor with either or both of the left and right wind direction plates and the upper and lower wind direction plates, By performing the person detection operation, the presence / absence of the occupant and the position of the occupant can be estimated.

この一例として、横流ファンを縦方向に設置した図39に示すような空気調和機にも本発明を適用でき、この場合、左右方向の検知を左右風向板の位置を変えて行い、遠近方向の検知を上下に配置した赤外線センサで行うなどの工夫を加えることで同様の効果を実現することができる。   As an example of this, the present invention can also be applied to an air conditioner as shown in FIG. 39 in which a cross flow fan is installed in the vertical direction. In this case, the left and right direction detection is performed by changing the position of the left and right wind direction plates. The same effect can be realized by adding ingenuity such as performing detection with infrared sensors arranged vertically.

以上説明したように、請求項1記載の赤外線検知装置を有する空気調和機によれば、1対の赤外線センサと、1対のフレネルレンズと、前記赤外線センサを固定する1対の台座を搭載した基板を備え、上記1対の赤外線センサは同一の赤外線センサを用いて異なる方向に向くように上記台座に固定され、上記1対のフレネルレンズ及び台座も同一のものを用いる。   As described above, according to the air conditioner having the infrared detecting device according to claim 1, the pair of infrared sensors, the pair of Fresnel lenses, and the pair of pedestals for fixing the infrared sensors are mounted. A pair of infrared sensors is provided on the pedestal so as to face different directions using the same infrared sensor, and the same pair of Fresnel lenses and pedestals are also used.

これにより、赤外線センサを異なる方向に向けて搭載するので左右2個の赤外線センサで室内を大きく3つの領域に分けることができ、人の居る部分に向けて自動的に空調空気を選択的に送るとか、送らないとかの制御ができ、煩わしい操作をすることなしに在室者の快適性を維持しつつ、省エネ運転するなどの利便性や満足度が高く、地球環境にも優しい空気調和運転ができる。このように、利便性が高く、快適性を維持しつつ、省エネ運転ができる空気調和機が得られる。   As a result, the infrared sensor is mounted in different directions, so the left and right infrared sensors can divide the room into three main areas and automatically send conditioned air to the part where people are present. It is possible to control whether or not to send, and while maintaining the comfort of the occupants without having to perform troublesome operations, it is highly convenient and satisfying, such as energy-saving operation, and air conditioning operation that is friendly to the global environment it can. In this way, an air conditioner that is highly convenient and can perform energy saving operation while maintaining comfort can be obtained.

このとき、左右の赤外線センサ,フレネルレンズ,台座を共用することで製作のための専用工具が削減でき、製作工程や部品在庫の管理も簡単になって、製作コストを圧縮できる。   At this time, by sharing the left and right infrared sensors, the Fresnel lens, and the pedestal, it is possible to reduce the number of dedicated tools for production, simplify the production process and management of parts inventory, and reduce the production cost.

また、赤外線センサ,フレネルレンズ,台座、基板を一体にできるので製造時やサービス時の取扱いが簡便になり、ミスを防ぐことができる。   Further, since the infrared sensor, Fresnel lens, pedestal, and substrate can be integrated, handling at the time of manufacture and service is simplified, and mistakes can be prevented.

このため、部品を共用して生産コストを節減できる赤外線検知装置を有する空気調和機を得ることができる。   For this reason, the air conditioner which has an infrared rays detection apparatus which can reduce production cost by sharing components can be obtained.

また、請求項2記載の赤外線検知装置を有する空気調和機によれば、前記1対の赤外線センサは焦電型の赤外線センサであり、その中心軸が交わるように、台座を介して、フレネルレンズと共に基板に搭載され、上記赤外線センサは中心軸の方向に延びる、3本の信号線を有し、上記台座は前記基板に装着された状態で中心軸が基板と所定の角度で交差し、上記信号線が貫通するための少なくとも3個以上の貫通孔と、上記基板との装着面に複数の位置決め突起と、上記赤外線センサの取付部と、上記フレネルレンズの係着部を有し、上記基板は上記位置決め突起が貫入する複数の位置決め孔を2組と、上記信号線が貫通する3個の貫通孔の組を2組有し、上記フレネルレンズは上記台座に係着する係着脚と、誤組立て防止部を有する。   Further, according to the air conditioner having the infrared detecting device according to claim 2, the pair of infrared sensors are pyroelectric infrared sensors, and the Fresnel lens is interposed via the pedestal so that the central axes thereof intersect. And the infrared sensor has three signal lines extending in the direction of the central axis, and the pedestal is mounted on the substrate and the central axis intersects the substrate at a predetermined angle. A substrate having at least three or more through holes for allowing signal lines to pass therethrough, a plurality of positioning protrusions on a mounting surface of the substrate, a mounting portion of the infrared sensor, and an engaging portion of the Fresnel lens; Has two sets of a plurality of positioning holes through which the positioning protrusions penetrate and two sets of three through holes through which the signal line penetrates, and the Fresnel lens is an engaging leg for engaging the pedestal; Has a misassembly prevention part.

これにより、例えば、特定な領域に日射が当ったり、加熱器のオンオフがあった時には一時的に検知出力は増加するが、赤外線センサが焦電型のため、じきに、背景温度と捉えられるようになって、検知され無くなって、誤って人有りと判断されることは無い。   As a result, for example, when a specific area is exposed to sunlight or the heater is turned on / off, the detection output temporarily increases. However, since the infrared sensor is a pyroelectric type, it will soon be recognized as the background temperature. Therefore, it will not be detected and it will not be mistakenly determined that there is a person.

また、サーモパイルのような高価なセンサを使用しなくて済むので、製造コストを下げることができる。   Further, since it is not necessary to use an expensive sensor such as a thermopile, the manufacturing cost can be reduced.

また、両中心軸を交差させることで、設計上の基準点が明確になり、各部品の位置や傾斜角度の決定や赤外線センサの検知区域の推定が容易になる。   In addition, by intersecting both central axes, the design reference point becomes clear, and it becomes easy to determine the position and inclination angle of each component and to estimate the detection area of the infrared sensor.

また、台座の中心軸と基板とを所定の角度で交差させることで、室内を適切な範囲に区分して人の在否を検知でき、調整の必要が無い。   In addition, by crossing the center axis of the pedestal and the substrate at a predetermined angle, it is possible to detect the presence or absence of a person by dividing the room into an appropriate range, and there is no need for adjustment.

また、赤外線センサ,台座,フレネルレンズ,基板を組立てる時に互いの取付部,係着部,位置決め部,信号線貫通部が適切に配置されていて、組立てに迷うことが無く、誤組立ても防ぐことができる。   In addition, when assembling the infrared sensor, pedestal, Fresnel lens, and board, each other's mounting part, engaging part, positioning part and signal line penetration part are properly arranged, so there is no hesitation in assembling and preventing misassembly. Can do.

このため、外乱に強く、部品コストが低減され、設計容易,組立て簡単で誤組立てを回避できる赤外線検知装置を有する空気調和機を得ることができる。   Therefore, it is possible to obtain an air conditioner having an infrared detecting device that is resistant to disturbances, has reduced component costs, is easy to design, is easy to assemble, and can avoid misassembly.

また、請求項3記載の赤外線検知装置を有する空気調和機によれば、前記赤外線センサの信号線は中心軸に4回対称の位置の3ヶ所に配置され、前記台座は上記赤外線センサの前記取付部は中心軸に2回対称の形状に形成され、前記フレネルレンズの前記係着部は中心軸に2回対称の形状に形成され、上記赤外線センサの上記信号線が貫通するための少なくとも3個以上の前記貫通孔を、中心軸に2回対称の位置に有し、前記基板は台座搭載面が両中心軸が成す角を2等分する直線に垂直に設けられ、前記2組の複数の位置決め孔は、上記2等分する直線に2回対称に配置され、前記3個の貫通孔の2組は、両中心軸と台座搭載面の交点間の距離だけ、平行移動した位置に配置され、上記フレネルレンズは2本の中心軸を含む中心軸平面に非対称に形成され、分割された小フレネルレンズ群を有し、前記係着脚は中心軸に2回対称に形成され、前記誤組立て防止部は、中心軸で上記中心軸平面に交わる中心軸直交平面に対称で、且つ、上記中心軸平面に対して非対称に配置されている。   According to the air conditioner having the infrared detecting device according to claim 3, the signal lines of the infrared sensor are arranged at three positions that are four times symmetrical with respect to the central axis, and the pedestal is attached to the infrared sensor. And the engaging portion of the Fresnel lens is formed in a two-fold symmetrical shape with respect to the central axis so that the signal line of the infrared sensor passes therethrough. The above-described through-hole is provided at a position that is symmetrical twice with respect to the central axis, and the base mounting surface is provided perpendicular to a straight line that bisects the angle formed by both central axes, and the two sets of the plurality of sets The positioning holes are arranged symmetrically twice with respect to the above-mentioned bisecting straight line, and the two sets of the three through holes are arranged at positions translated by the distance between the intersections of both central axes and the pedestal mounting surface. The Fresnel lens is not in a central axis plane including two central axes. A small Fresnel lens group that is formed in a divided manner, the engaging legs are formed symmetrically with respect to a central axis, and the misassembly prevention portion is orthogonal to the central axis plane that intersects the central axis plane with the central axis They are symmetrical with respect to the plane and asymmetric with respect to the central axis plane.

これにより、台座は左右非対称,上下対称に形成され、赤外線センサの信号線の取出し部は上下左右非対称になる。   As a result, the pedestal is formed asymmetrical in the left-right direction and symmetrical in the vertical direction, and the signal line takeout part of the infrared sensor is asymmetrical in the vertical and horizontal directions.

フレネルレンズは検知範囲をできるだけ一様に検知できるよう、下側は粗く、上側は細かく分割され、上下は非対称,左右は対称に形成され、台座との係着部の見やすいところに誤組立てを注意する突起が設けられる。   In order to detect the detection range as uniformly as possible, the Fresnel lens is rough on the lower side, finely divided on the upper side, asymmetrical on the top and bottom, and symmetrically on the left and right. Protrusions are provided.

更に、基板は左右の台座の位置決め孔が中央直交平面に対して対称に、更に、赤外線センサの信号線の貫通孔が平行移動の位置に孔設される。このようにすることで、台座を左右反転させて基板に取り付け、左右の赤外線検知装置に同一のフレネルレンズ,台座,赤外線センサを使用でき、部品のコストが低減される。   Further, in the substrate, the positioning holes of the left and right pedestals are symmetrical with respect to the central orthogonal plane, and further, the through holes of the signal lines of the infrared sensor are provided at the positions of parallel movement. By doing so, the pedestal can be reversed and attached to the substrate, and the same Fresnel lens, pedestal, and infrared sensor can be used for the left and right infrared detection devices, thereby reducing the cost of components.

更にまた、基板に台座を装着するときは、赤外線センサの中心軸方向に台座の向きをあわせて取り付ける。このとき、台座の取付姿勢は明らかに違うので、台座の取付方向を誤る恐れは非常に小さい。次に赤外線センサの信号線を台座の複数の貫通孔に挿入する。このとき、台座が載っている基板には正しい信号線の配置に応じた位置にしか貫通孔が開いていないので、赤外線センサが誤った姿勢に取り付けられることは無い。   Furthermore, when the pedestal is mounted on the substrate, the pedestal is attached in the direction of the central axis of the infrared sensor. At this time, since the mounting orientation of the pedestal is clearly different, there is very little risk of erroneous mounting direction of the pedestal. Next, the signal line of the infrared sensor is inserted into the plurality of through holes of the base. At this time, since the through hole is opened only at a position corresponding to the correct arrangement of the signal line on the board on which the pedestal is placed, the infrared sensor is not attached in a wrong posture.

次に、フレネルレンズをかぶせる時には、フレネルレンズの見やすい位置に設けた誤組立て防止突起を見てその位置を確認しながら、フレネルレンズを台座に取り付けるので、ここでも誤ってフレネルレンズを180度回転させた誤った姿勢で組立てる恐れは極めて小さい。   Next, when the Fresnel lens is put on, the Fresnel lens is attached to the pedestal while checking the position of the Fresnel lens at the easy-to-see position so that the Fresnel lens can be rotated. The risk of assembly in the wrong posture is very small.

このため、左右のフレネルレンズ,台座,赤外線センサを共用して、赤外線センサ信号線の非対称配置とフレネルレンズの誤組立て防止突起で誤組立てを防ぎ、品質が一様で、信頼性が高く、生産コストも節減できる赤外線検知装置を有する空気調和機を得ることができる。   For this reason, the right and left Fresnel lenses, pedestals, and infrared sensors are shared, and the asymmetrical arrangement of the infrared sensor signal lines and the incorrect assembly prevention protrusions of the Fresnel lens prevent erroneous assembly, and the quality is uniform and reliable. It is possible to obtain an air conditioner having an infrared detection device that can reduce costs.

また、請求項4記載の赤外線検知装置を有する空気調和機によれば、前記台座の装着面に設けられた複数の位置決め突起を、中心軸と装着面の交点から装着面に立てた垂線に非回転対称に設けた。   According to the air conditioner having the infrared detecting device according to claim 4, the plurality of positioning protrusions provided on the mounting surface of the pedestal are not connected to a vertical line standing on the mounting surface from the intersection of the central axis and the mounting surface. It was provided in rotational symmetry.

これにより、台座の位置決め突起を左右上下非対称,非回転対称に形成し、位置決め突起が中心軸の周りに回転移動した位置関係に為らないようにする。   As a result, the positioning protrusions of the pedestal are formed asymmetrical in the left-right direction and non-rotationally symmetrical so that the positioning protrusions do not have a positional relationship that rotates around the central axis.

また、基板には左右の台座の位置決め孔が装置中央軸に2回対称に、更に、赤外線センサの信号線の貫通孔が平行移動の位置に孔設される。このようにすることで、左右の赤外線検知装置に同一のフレネルレンズ,台座,赤外線センサを使用でき、部品のコストが低減される。   Further, the left and right pedestal positioning holes are provided twice symmetrically with respect to the central axis of the apparatus, and the signal line through hole of the infrared sensor is provided at the position of parallel movement in the substrate. By doing so, the same Fresnel lens, pedestal, and infrared sensor can be used for the left and right infrared detectors, and the cost of the components is reduced.

また、基板に台座を装着するときは、基板の位置決め孔に台座の位置決め突起を挿入することで、台座の取付姿勢が一意的に定まり、台座の取付方向を誤る恐れは皆無となる。   Further, when the pedestal is mounted on the substrate, the mounting posture of the pedestal is uniquely determined by inserting the positioning protrusion of the pedestal into the positioning hole of the substrate, and there is no possibility of erroneous mounting direction of the pedestal.

このため、更に台座の基板への誤装着も防止できる赤外線検知装置を有する空気調和機を得ることができる。   For this reason, the air conditioner which has the infrared rays detection apparatus which can prevent the erroneous mounting | wearing to the board | substrate of a base further can be obtained.

また、請求項5記載の赤外線検知装置を有する空気調和機によれば、前記基板に、前記フレネルレンズに設けた前記誤組立て防止部が貫入する誤組立て防止孔を有し、上記誤組立て防止孔は、前記2等分する直線で交わる前記中心軸平面に垂直な中央直交平面に面対称で、且つ、前記中心軸平面に非対称な位置に設けられ、上記フレネルレンズの上記誤組立て防止部の長さは、上記フレネルレンズを前記台座を介して上記基板に取り付けたときに、上記基板に近い側の上記誤組立て防止部が上記基板の上記誤組立て防止孔に貫入し、上記基板に遠い側の上記誤組立て防止部が上記基板に達しない長さに形成されている。   Further, according to the air conditioner having the infrared detecting device according to claim 5, the substrate has a misassembly prevention hole through which the misassembly prevention portion provided in the Fresnel lens penetrates, and the misassembly prevention hole. Is provided in a position that is symmetrical with respect to a central orthogonal plane perpendicular to the central axis plane that intersects the bisecting straight line and is asymmetric with respect to the central axis plane, and is the length of the misassembly prevention portion of the Fresnel lens. When the Fresnel lens is attached to the substrate via the pedestal, the misassembly prevention portion on the side close to the substrate penetrates into the misassembly prevention hole of the substrate and is located on the side far from the substrate. The misassembly prevention portion is formed to a length that does not reach the substrate.

これにより、フレネルレンズの誤組立て防止突起の片側が基板まで達する長さに形成される。   Thus, the Fresnel lens is formed in such a length that one side of the misassembly prevention protrusion reaches the substrate.

また、基板には中央直交平面に対して対称に誤組立て防止孔が孔設される。このようにすることで、左右の赤外線検知装置に同一のフレネルレンズ,台座,赤外線センサを使用でき、部品のコストが低減される。   The substrate is provided with a misassembly prevention hole symmetrically with respect to the central orthogonal plane. By doing so, the same Fresnel lens, pedestal, and infrared sensor can be used for the left and right infrared detectors, and the cost of the components is reduced.

また、基板に装着した台座にフレネルレンズをかぶせる時には、フレネルレンズを正しく取り付けた時には前記誤組立て防止部が該基板の誤組立て防止孔に貫入し、フレネルレンズの取り付けが妨げられることは無い。しかし、フレネルレンズを180度回転させた正しくない姿勢に取り付けようとすると前記誤組立て防止部が基板にぶつかり、フレネルレンズの取り付けが妨げられる。このように、フレネルレンズの誤組立てが防止される。   Further, when the Fresnel lens is put on the pedestal mounted on the substrate, when the Fresnel lens is correctly attached, the misassembly prevention portion penetrates into the misassembly prevention hole of the substrate, and the attachment of the Fresnel lens is not hindered. However, if the Fresnel lens is to be mounted in an incorrect posture rotated by 180 degrees, the misassembly prevention unit hits the substrate, and the mounting of the Fresnel lens is hindered. In this way, incorrect assembly of the Fresnel lens is prevented.

このため、更にレンズの基板への誤組立ても防止できる赤外線検知装置を有する空気調和機を得ることができる。   For this reason, the air conditioner which has the infrared rays detection apparatus which can prevent also incorrect assembly to the board | substrate of a lens can be obtained.
