以下、本発明の実施例を、図面を参照しながら説明する。なお、各図および各実施例において、同一又は類似の構成要素には同じ不号を付し、説明を省略する。 Embodiments of the present invention will be described below with reference to the drawings. In each figure and each example, the same or similar components are denoted by the same reference numerals and description thereof is omitted.
図１は本実施形態に係る空気調和機の外観を示す正面図である。空気調和機は、室内機１と、室外機２と、リモコン３と、から構成され、室内機１と室外機２とは図示していない冷媒配管で接続され、周知の冷媒サイクルによって、室内機１が設置されている室内を空調する。また、室内機１と室外機２とは、通信ケーブル（図示せず）を介して互いに情報を送受信するようになっている。 FIG. 1 is a front view showing the appearance of the air conditioner according to the present embodiment.

また、空気調和機の室内機１の正面には、詳細を後述する撮像手段２６と温度検出手段２７が設けられている。 In addition, an imaging unit 26 and a temperature detection unit 27, which will be described in detail later, are provided in front of the indoor unit 1 of the air conditioner.
また、室内機には、室内機１に取り込む空気の温度を測定する室温センサと、湿度センサと、照度センサとから成るセンサ部４がある。室外機２にも、同様に、外気温センサが設けられている。 The indoor unit includes a sensor unit 4 including a room temperature sensor that measures the temperature of air taken into the indoor unit 1, a humidity sensor, and an illuminance sensor. The outdoor unit 2 is similarly provided with an outside air temperature sensor.
１１は電装品であり、当該空気調和機の制御をおこなう制御手段７が構成されている。詳細は、図８により説明する。 Reference numeral 11 denotes an electrical component, which includes a control means 7 that controls the air conditioner. Details will be described with reference to FIG.
図２は、室内機１の側断面図である。筐体ベース８は、室内熱交換器９、送風ファン１０、電装品１１（図１参照）、センサ部４（図１参照）、撮像手段２６、温度検出手段２７などの内部構造体を収容している。 FIG. 2 is a side sectional view of the indoor unit 1. The housing base 8 accommodates internal structures such as the indoor heat exchanger 9, the blower fan 10, the electrical component 11 (see FIG. 1), the sensor unit 4 (see FIG. 1), the imaging means 26, and the temperature detecting means 27. ing.
室内熱交換器９は、複数本の伝熱管を有し、送風ファン１０により室内機１内に取り込まれた空気を、伝熱管を通流する冷媒と熱交換させ、前記空気を加熱又は冷却するように構成されている。なお、伝熱管は、前記した冷媒配管（図示せず）に連通し、周知の冷媒サイクル（図示せず）の一部を構成している。 The indoor heat exchanger 9 has a plurality of heat transfer tubes, heats the air taken into the indoor unit 1 by the blower fan 10 with a refrigerant flowing through the heat transfer tubes, and heats or cools the air. It is configured as follows. The heat transfer tube communicates with the above-described refrigerant pipe (not shown) and constitutes a part of a known refrigerant cycle (not shown).
左右風向板１３は、制御手段７（図８参照）からの指示に従い、下部に設けた回動軸（図示せず）を支点にして左右風向板１３用モータ（図示せず）により回動される。 The left and right wind direction plates 13 are rotated by a motor for left and right wind direction plates 13 (not shown) around a rotation shaft (not shown) provided at the lower portion in accordance with an instruction from the control means 7 (see FIG. 8). The
上下風向板１４は、制御手段７（図８参照）からの指示に従い、両端部に設けた回動軸（図示せず）を支点にして上下風向板１４用にモータ（図示せず）により回動される。 The vertical wind direction plate 14 is rotated by a motor (not shown) for the vertical wind direction plate 14 using pivot shafts (not shown) provided at both ends as fulcrums according to instructions from the control means 7 (see FIG. 8). Moved.
前面パネル１５は、室内機１の前面を覆うように設置されており、下端を軸として前面パネル１５用モータ（図示せず）により回動可能な構成となっている。ちなみに、前面パネル１５を、下端に固定されるものとして構成してもよく、回動できない構成であってもよい。 The front panel 15 is installed so as to cover the front surface of the indoor unit 1, and is configured to be rotatable by a motor (not shown) for the front panel 15 with the lower end as an axis. Incidentally, the front panel 15 may be configured to be fixed to the lower end or may not be able to rotate.
図２に示す送風ファン１０が回転することによって、空気吸込み口１７及びフィルタ１６を介して、室内機１の前面から室内空気を取り込み、室内熱交換器９で熱交換された空気が吹出し風路１８に導かれる。さらに、吹出し風路１８に導かれた空気は、左右風向板１３及び上下風向板１４によって風向きを調整され、空気吹出し口１９から外部に送り出されて室内を空調する。 When the blower fan 10 shown in FIG. 2 rotates, the indoor air is taken in from the front surface of the indoor unit 1 via the air suction port 17 and the filter 16, and the air exchanged by the indoor heat exchanger 9 is blown out. 18 leads to. Further, the air guided to the blowout air passage 18 is adjusted in the wind direction by the left and right wind direction plates 13 and the up and down wind direction plates 14 and is sent to the outside from the air blowing port 19 to air-condition the room.
つまり、送風ファン１０の回転速度により吹き出し風量が制御され、左右風向板１３の回動により左右の吹出し方向が制御され、上下風向板１４の回動により上下の吹出し方向が制御される。 That is, the amount of blown air is controlled by the rotation speed of the blower fan 10, the left and right blowing directions are controlled by the rotation of the left and right wind direction plates 13, and the upper and lower blowing directions are controlled by the rotation of the upper and lower wind direction plates 14.
撮像手段２６は、例えば、ＣＣＤ（Ｃｈａｒｇｅ Ｃｏｕｐｌｅｄ Ｄｅｖｉｃｅ）イメージセンサ２６ｂ（図３ｂ参照）であり、前面パネル１５の左右方向中央の下部に設置されている。また、温度検出手段２７は、例えば横×縦が１×１画素、４×４画素、１×８画素で構成されるサーモパイル２７ｂ（図３ａ参照）であり、前面パネル１５の左右方向中央の下部に設置されている。本実施例では、１×８画素で構成されるサーモパイル２７ｂを使用した場合について述べる。 The image pickup means 26 is, for example, a CCD (Charge Coupled Device) image sensor 26b (see FIG. 3B), and is installed at the lower part of the center of the front panel 15 in the left-right direction. Further, the temperature detection means 27 is a thermopile 27b (see FIG. 3a) composed of, for example, horizontal × vertical 1 × 1 pixel, 4 × 4 pixel, and 1 × 8 pixel. Is installed. In this embodiment, a case where a thermopile 27b composed of 1 × 8 pixels is used will be described.
撮像手段２６と温度検出手段２７は、レンズの光軸３６が水平線３７に対して所定角度だけ下方を向くように設置されており、室内機１が設置されている室内を適切に撮像できるようになっている。撮像手段２６が下方を向く角度は、温度検出手段２７が下方を向く角度とほぼ同じである。 The imaging means 26 and the temperature detection means 27 are installed such that the optical axis 36 of the lens faces downward with respect to the horizontal line 37 by a predetermined angle so that the room in which the indoor unit 1 is installed can be appropriately imaged. It has become. The angle at which the image pickup means 26 faces downward is substantially the same as the angle at which the temperature detection means 27 faces downward.
撮像手段２６と温度検出手段２７の鉛直方向の検出範囲が異なる場合、検出範囲の上端をそろえる。あるいは、下端をそろえても良い。 When the detection ranges in the vertical direction of the imaging unit 26 and the temperature detection unit 27 are different, the upper ends of the detection ranges are aligned. Alternatively, the lower ends may be aligned.
撮像手段２６と温度検出手段２７の水平方向の画角は略同じ角度である。あるいは、一方が他方より大きく、回動することにより画角を変更することでほぼ同等の画角を得ても良い。撮像手段２６と温度検出手段２７は互いに水平方向または鉛直方向に位置するように設けられる。 The angle of view in the horizontal direction of the image pickup means 26 and the temperature detection means 27 is substantially the same angle. Alternatively, one may be larger than the other, and a substantially equivalent angle of view may be obtained by changing the angle of view by turning. The imaging means 26 and the temperature detection means 27 are provided so as to be positioned in the horizontal direction or the vertical direction.
また、撮像手段２６と温度検出手段２７は室内機１の前面中央部や前面上部など空間の検出が可能な位置に近接して設けることが望ましい。これにより、撮像手段２６の取得画像と温度検出手段２７の取得画像のずれ量を小さくすることができる。 In addition, it is desirable that the image pickup unit 26 and the temperature detection unit 27 be provided close to a position where space can be detected, such as the front central portion or the upper front portion of the indoor unit 1. Thereby, the deviation | shift amount of the acquired image of the imaging means 26 and the acquired image of the temperature detection means 27 can be made small.
また、撮像手段２６あるいは温度検出手段２７は、同一の画角で部屋のより広い範囲を見られるよう、前面パネル１５の上端にあってもよい。 Further, the imaging means 26 or the temperature detection means 27 may be at the upper end of the front panel 15 so that a wider range of the room can be seen with the same angle of view.
つぎに、図３ａと図３ｂにより、撮像手段２６と温度検出手段２７による撮像について説明する。撮像手段２６は、６４０×４８０画素のＣＣＤイメージセンサ２６ｂにより構成され、温度検出手段２７は１×８画素のサーモパイル２７ｂにより構成される。そして、ＣＣＤイメージセンサ２６ｂやサーモパイル２７ｂの前面にはレンズが設けられており、視野像がセンサに結像される。 Next, imaging by the imaging means 26 and the temperature detection means 27 will be described with reference to FIGS. 3a and 3b. The imaging means 26 is constituted by a CCD image sensor 26b having 640 × 480 pixels, and the temperature detecting means 27 is constituted by a thermopile 27b having 1 × 8 pixels. A lens is provided in front of the CCD image sensor 26b and the thermopile 27b, and a field image is formed on the sensor.
サーモパイル２７ｂの検出素子は、１次元配置された受熱素子となっている。図３ａにしめすように、検出素子の配列方向を回転軸にしてサーモパイル２７ｂを回動することにより、検出素子の配列方向に垂直な方向に走査する。これにより、縦方向に８画素の２次元の放射熱像を取得することができる。取得画像の走査方向（水平方向）の画素数については後述する。 The detection element of the thermopile 27b is a heat receiving element arranged one-dimensionally. As shown in FIG. 3a, the thermopile 27b is rotated about the arrangement direction of the detection elements as a rotation axis, thereby scanning in a direction perpendicular to the arrangement direction of the detection elements. Thereby, a two-dimensional radiant heat image of 8 pixels can be acquired in the vertical direction. The number of pixels in the scanning direction (horizontal direction) of the acquired image will be described later.
ＣＣＤイメージセンサ２６ｂは２次元の撮像素子であるが、撮像手段２６の取得画像範囲を広くするために、図３ｂにしめすように、ＣＣＤイメージセンサ２６ｂの縦方向を回転軸にしてＣＣＤイメージセンサ２６ｂを回動し、水平方向の走査をおこなう。これにより、ＣＣＤイメージセンサ２６ｂの水平方向の画素数より大きな撮像画像を得ることができる。 The CCD image sensor 26b is a two-dimensional image pickup device, but in order to widen the acquired image range of the image pickup means 26, as shown in FIG. 3B, the CCD image sensor 26b has the vertical direction of the CCD image sensor 26b as the rotation axis. Rotate to scan in the horizontal direction. Thereby, a captured image larger than the number of pixels in the horizontal direction of the CCD image sensor 26b can be obtained.
図４は、撮像手段２６のＣＣＤイメージセンサ２６ｂと温度検出手段２７のサーモパイル２７ｂの回転角度の関係を説明する図である。ここで、ＣＣＤイメージセンサ２６ｂは、６０°の画角をもち、サーモパイル２７ｂは、５°の画角をもち、撮像手段２６と温度検出手段２７は、水平方向が１５０°の画角で、同じ視野の画像取得をおこなうものとする。 FIG. 4 is a diagram for explaining the relationship between the rotation angle of the CCD image sensor 26b of the image pickup means 26 and the thermopile 27b of the temperature detection means 27. Here, the CCD image sensor 26b has an angle of view of 60 °, the thermopile 27b has an angle of view of 5 °, and the imaging means 26 and the temperature detection means 27 have the same angle of view with a horizontal direction of 150 °. It is assumed that an image of the visual field is acquired.
図４の実線はＣＣＤイメージセンサ２６ｂの１回の撮像角度範囲を示し、点線はサーモパイル２７ｂの１回の検出角度範囲を示している。図に示されるように１５０°の画角の取得画像を得るには、サーモパイル２７ｂは、中央の左右７５°の範囲を５°の回転角度ごとに、放射熱像を取得し、ＣＣＤイメージセンサ２６ｂは、中央と左右４５°の３つの回転角度で撮像をおこない画像取得をおこなえばよい。 A solid line in FIG. 4 indicates a single imaging angle range of the CCD image sensor 26b, and a dotted line indicates a single detection angle range of the thermopile 27b. As shown in the figure, in order to obtain an acquired image having an angle of view of 150 °, the thermopile 27b acquires a radiant heat image in the central left and right range of 75 ° for each rotation angle of 5 °, and the CCD image sensor 26b. The image acquisition may be performed by performing imaging at three rotation angles of 45 ° to the left and right of the center.
図５ａと図５ｂは、上記の条件で撮像をおこなった撮像手段２６と温度検出手段２７の撮像結果をしめす図である。撮像手段２６は、水平方向が１５０°の画角で、１６００×４８０の画素数の画像取得がおこなえる。温度検出手段２７は、水平方向が１５０°の画角で、３０×８の画素数の熱画像取得がおこなえる。 5a and 5b are diagrams showing the imaging results of the imaging means 26 and the temperature detection means 27 that have imaged under the above conditions. The imaging means 26 can acquire an image having a pixel number of 1600 × 480 at an angle of view of 150 ° in the horizontal direction. The temperature detection unit 27 can acquire a thermal image of 30 × 8 pixels at a field angle of 150 ° in the horizontal direction.
このとき、撮像手段２６による撮像画像には、重複する領域があるので、適宜削除あるいは平均化して、上記の画素数の画像取得をおこなう。 At this time, since there are overlapping areas in the captured image by the imaging unit 26, the image acquisition with the above-described number of pixels is performed by appropriately deleting or averaging.
上記の取得画像の画素数は一例であって、取得する画角や、使用するＣＣＤイメージセンサ２６ｂやサーモパイル２７ｂの種類によって種々選択可能であることはいうまでもない。 The number of pixels of the acquired image is merely an example, and it goes without saying that various selections can be made depending on the angle of view to be acquired and the type of CCD image sensor 26b or thermopile 27b to be used.
なお、一見、サーモパイル２７ｂの分解能が低いように思えるが、実施例のように空気調和機の送風制御のために室内の温度分布を測定する用途であれば、上記の分解能であれば充分に制御をおこなうことができる。もちろん、高分解能であることが望ましいことは言うまでもない。 At first glance, it seems that the resolution of the thermopile 27b is low, but if it is an application for measuring the temperature distribution in the room for air blow control of the air conditioner as in the embodiment, the above resolution is sufficient. Can be done. Of course, it is needless to say that high resolution is desirable.
つぎに、サーモパイル２７ｂあるいはＣＣＤイメージセンサ２６ｂを回動させる機構について説明する。図６ａと図６ｂは機構概要をしめす図である。ここで、サーモパイル２７ｂあるいはＣＣＤイメージセンサ２６ｂを回動する駆動源は、ステッピングモータ４２を使用するものとする。 Next, a mechanism for rotating the thermopile 27b or the CCD image sensor 26b will be described. 6a and 6b are diagrams showing an outline of the mechanism. Here, it is assumed that the stepping motor 42 is used as a drive source for rotating the thermopile 27b or the CCD image sensor 26b.
図６ａに示す機構では、サーモパイル２７ｂあるいはＣＣＤイメージセンサ２６ｂを回動する回転軸とステッピングモータ４２の駆動軸を、ギアを介して接続するものである。ステップ数の小さなステッピングモータ４２であっても、ギア比を選択することにより所望の回転角を得ることができる。 In the mechanism shown in FIG. 6a, the rotating shaft that rotates the thermopile 27b or the CCD image sensor 26b and the drive shaft of the stepping motor 42 are connected via a gear. Even a stepping motor 42 with a small number of steps can obtain a desired rotation angle by selecting a gear ratio.
図６ｂに示す機構では、サーモパイル２７ｂあるいはＣＣＤイメージセンサ２６ｂを回動する回転軸とステッピングモータ４２の駆動軸を、４節リンクにより接続し、回転運動を揺動運動に変換することができる。 In the mechanism shown in FIG. 6b, the rotary shaft that rotates the thermopile 27b or the CCD image sensor 26b and the drive shaft of the stepping motor 42 can be connected by a four-bar link to convert the rotary motion into a swing motion.
上述のギアやリンクにより駆動軸の接続をおこなった場合は、ギアのバックラッシュやリンクの“あそび”により、回動位置精度に誤差が生じることがある。このため、撮像時のサーモパイル２７ｂあるいはＣＣＤイメージセンサ２６ｂの撮像時の回動方向を一方向にして“あそび”による回動角の誤差が生じないようにすることが望ましい。また、予め“あそび”を吸収する調整量を求めておき、回動方向が反転する際に調整をおこなうようにしてもよい。 When the drive shaft is connected by the above-described gear or link, an error may occur in the rotational position accuracy due to gear backlash or link “play”. For this reason, it is desirable that the rotation direction at the time of imaging of the thermopile 27b or the CCD image sensor 26b at the time of imaging is set to one direction so that an error of the rotation angle due to “play” does not occur. Further, an adjustment amount for absorbing “play” may be obtained in advance, and adjustment may be performed when the rotation direction is reversed.
図７は、温度検出手段２７の鉛直断面の撮像状態を示す図である。上述のとおり、温度検出手段２７のサーモパイル２７ｂは、縦方向に８素子から構成されている。図７の１から８の領域の放射熱が受熱素子により検出される。図７から分かるように、撮像結果の上側と下側がそれぞれ室内の壁と床に対応している。 FIG. 7 is a diagram illustrating an imaging state of a vertical cross section of the temperature detection unit 27. As described above, the thermopile 27b of the temperature detecting means 27 is composed of eight elements in the vertical direction. The radiant heat in the region 1 to 8 in FIG. 7 is detected by the heat receiving element. As can be seen from FIG. 7, the upper and lower sides of the imaging result correspond to the indoor wall and floor, respectively.
図８は、実施例の空気調和機の制御回路の構成図である。 FIG. 8 is a configuration diagram of a control circuit of the air conditioner according to the embodiment.
上述の撮像手段２６のＣＣＤイメージセンサ２６ｂと温度検出手段２７のサーモパイル２７ｂは、それぞれ独立に、センサ走査制御部５０により回動駆動される。ＣＣＤイメージセンサ２６ｂとサーモパイル２７ｂの出力信号は、温度分布生成・判定処理部５により、図５ａや図５ｂに示す２次元の撮像画像と放射熱画像が生成される。 The CCD image sensor 26b of the imaging unit 26 and the thermopile 27b of the temperature detection unit 27 are independently driven to rotate by the sensor scanning control unit 50. From the output signals of the CCD image sensor 26b and the thermopile 27b, the temperature distribution generation / determination processing unit 5 generates a two-dimensional captured image and a radiant heat image shown in FIGS. 5a and 5b.
温度分布生成・判定処理部５は、上記の２次元の撮像画像と放射熱画像を解析して、レイアウト状態、人物の有無やその人数やその活動率、温度分布を、算出する。 The temperature distribution generation / determination processing unit 5 analyzes the two-dimensional captured image and the radiant heat image, and calculates the layout state, the presence / absence of a person, the number of persons, the activity rate, and the temperature distribution.
そして、空調温度・風向処理部６は、この算出結果と、外気温センサ制御部５１、室温センサ制御部５２、湿度センサ制御部５３、照度センサ制御部５４の入力値と、リモコン制御部５５と通信するリモコン３による設定値を参照して、送風の温度・風量と方向等の制御量を決める。 Then, the air conditioning temperature / wind direction processing unit 6 calculates the calculation result, the input values of the outside air temperature sensor control unit 51, the room temperature sensor control unit 52, the humidity sensor control unit 53, the illuminance sensor control unit 54, the remote control control unit 55, With reference to the set values by the remote controller 3 that communicates, the control amount such as the temperature / air volume and direction of the air is determined.
機器制御手段７は、空調温度・風向処理部６からの指示に基づいて、室外機２の圧縮機駆動部２２ｂと室外機ファンモータ駆動２４と四方弁駆動部３４と電動弁駆動部３５を制御して、冷房・暖房をおこなう冷媒サイクルの制御をおこなうとともに、前記空調温度・風向処理部６の指示に基づいて、上下風向板駆動部１４ｂと左右風向板駆動部１３ｂと送風ファン駆動部１０ｂを制御して冷却風や暖房風を吹き出し方向・風量を制御する。 The device control means 7 controls the compressor drive unit 22b, the outdoor unit fan motor drive 24, the four-way valve drive unit 34, and the motorized valve drive unit 35 of the outdoor unit 2 based on instructions from the air conditioning temperature / wind direction processing unit 6. Then, the refrigerant cycle for cooling and heating is controlled, and on the basis of the instructions from the air conditioning temperature / wind direction processing unit 6, the up / down wind direction plate driving unit 14b, the left / right wind direction plate driving unit 13b, and the blower fan driving unit 10b are controlled. Control the cooling air and heating air to control the blowing direction and air volume.
また、空調温度・風向処理部６は、センサ走査制御部５０の動作状態を設定する。 Further, the air conditioning temperature / wind direction processing unit 6 sets the operation state of the sensor scanning control unit 50.
前記温度分布生成・判定処理部５と空調温度・風向処理部６と機器制御手段７は、マイクロプロセッサによるプログラム処理で実現される。 The temperature distribution generation / determination processing unit 5, the air conditioning temperature / wind direction processing unit 6, and the device control means 7 are realized by a program process by a microprocessor.
つぎに本実施例の具体的な処理内容を説明する。 Next, specific processing contents of this embodiment will be described.
まず、独立に撮像動作をおこなえる撮像手段２６と温度検出手段２７とにより、撮像画像と温度分布画像を生成する手順を説明する。本実施例では、撮像手段２６と温度検出手段２７を並行動作させて撮像タイミングのずれを小さくする方法について説明するが、空調する室内を静止状態と見なせる場合（人の移動を考慮しない場合等）には、撮像手段２６と温度検出手段２７により交互に撮像をおこなってもよい。 First, a procedure for generating a captured image and a temperature distribution image by the imaging unit 26 and the temperature detection unit 27 that can independently perform an imaging operation will be described. In this embodiment, a method for reducing the difference in imaging timing by operating the imaging unit 26 and the temperature detection unit 27 in parallel will be described. However, when the air-conditioned room can be regarded as a stationary state (such as not considering the movement of a person). Alternatively, the imaging unit 26 and the temperature detection unit 27 may alternately perform imaging.
図９は、撮像手段２６と温度検出手段２７の並行動作を説明する図である。図４の撮像手段２６と温度検出手段２７の回動角度の関係を基に説明する。 FIG. 9 is a diagram for explaining the parallel operation of the image pickup means 26 and the temperature detection means 27. Description will be made based on the relationship between the rotation angles of the image pickup means 26 and the temperature detection means 27 in FIG.
温度検出手段２７のサーモパイル２７ｂは、図４の３０ポイントの検出点で一定の回動角速度で駆動され、かつ、一定間隔で撮像（信号検出）される。これに対して、撮像手段２６のＣＣＤイメージセンサ２６ｂは、サーモパイル２７ｂの１０ポイントの検出点ごとに、回動動作をおこなうようにする。そして、ＣＣＤイメージセンサ２６ｂの撮像（信号検出）のタイミングはサーモパイル２７ｂの１０ポイントの検出点の範囲の中央とする。これにより、人物の撮像と温度検出のタイミングのずれを小さくする。 The thermopile 27b of the temperature detecting means 27 is driven at a constant rotational angular velocity at 30 detection points in FIG. 4 and is imaged (signal detection) at a constant interval. On the other hand, the CCD image sensor 26b of the image pickup means 26 performs a rotation operation at every 10 detection points of the thermopile 27b. The timing of imaging (signal detection) of the CCD image sensor 26b is set to the center of the range of 10 detection points of the thermopile 27b. As a result, the difference between the timing of image capturing and temperature detection is reduced.
より詳細には、サーモパイル２７ｂが図４に示した１から９の回動角度に在るときには、ＣＣＤイメージセンサ２６ｂは回度角度が１の位置にあり、サーモパイル２７ｂの回動角度が５の位置になったときに、ＣＣＤイメージセンサ２６ｂの撮像をおこなう。 More specifically, when the thermopile 27b is at a rotation angle of 1 to 9 shown in FIG. 4, the CCD image sensor 26b is at a position where the rotation angle is 1, and the rotation angle of the thermopile 27b is a position where the rotation angle is 5. Then, the CCD image sensor 26b is imaged.
つぎに、サーモパイル２７ｂの回動角度が１０の位置になったときに、ＣＣＤイメージセンサ２６ｂを回度角度１０の位置に駆動する。そして、サーモパイル２７ｂの回動角度が１５の位置になったときに、ＣＣＤイメージセンサ２６ｂの撮像をおこなう。 Next, when the rotation angle of the thermopile 27b reaches the position of 10, the CCD image sensor 26b is driven to the position of the rotation angle 10. Then, when the rotation angle of the thermopile 27b reaches a position of 15, the CCD image sensor 26b is imaged.
さらに、サーモパイル２７ｂの回動角度が１９の位置になったときに、ＣＣＤイメージセンサ２６ｂを回度角度１９の位置に駆動する。そして、サーモパイル２７ｂの回動角度が２６の位置になったときに、ＣＣＤイメージセンサ２６ｂの撮像をおこなう。 Further, when the rotation angle of the thermopile 27 b reaches the 19 position, the CCD image sensor 26 b is driven to the rotation angle 19 position. When the rotation angle of the thermopile 27b reaches the position 26, the CCD image sensor 26b is imaged.
上記の手順により、図５ａと図５ｂに示した撮像結果を得ることができる。前述のとおり、図は、撮像手段２６と温度検出手段２７により同一の視野を撮像したものである。撮像手段２６と温度検出手段２７の分解能の違いから、異なるマトリックスサイズとなっているが、座標位置には対応関係がある。したがって、図５ｂの特定座標の温度は、図５ａを参照することにより求めることができる。 With the above procedure, the imaging results shown in FIGS. 5a and 5b can be obtained. As described above, the figure is an image of the same field of view taken by the imaging means 26 and the temperature detection means 27. Although the matrix sizes are different due to the difference in resolution between the imaging means 26 and the temperature detection means 27, the coordinate positions have a corresponding relationship. Therefore, the temperature of the specific coordinate in FIG. 5b can be obtained by referring to FIG. 5a.
図１０ａと図１０ｂは、ひとりの人物が在室していた場合の例を示したもので、撮像手段２６と温度検出手段２７の撮像結果を重ねて記載したものとなっている。ただし、撮像手段２６の撮像結果は、マス目の表示が省略されている。 10a and 10b show an example in the case where one person is present in the room, and the imaging results of the imaging means 26 and the temperature detection means 27 are described in an overlapping manner. However, in the imaging result of the imaging means 26, the grid display is omitted.
図の人体を検出したマスは、例えば、既知の顔検出技術を使用して撮像手段２６の撮像画像から顔を検出し、検出した顔の画像中心座標を求め、この座標に対応する温度検出手段２７の撮像結果の位置を求めたものである。 For example, the mass that has detected the human body in the figure detects the face from the captured image of the imaging unit 26 using a known face detection technique, obtains the image center coordinates of the detected face, and the temperature detection unit corresponding to this coordinate 27 is the position of the imaging result.
図１０ａに示す顔検出位置（人体を検出したマス）の温度が、顔の表面温度になる。一般に、人の周囲温度は着衣温に近いと考えられるので、図１０ｂに示すように、温度検出手段２７の撮像結果において、顔検出位置（人体を検出したマス）の下方の左右のマスの温度が床温度とみなすことができる（図１０ｂでは、温度を抽出するマスと表記）。本実施例の撮像手段２６と温度検出手段２７は水平方向に回動走査して撮像しているため、顔検出したマスの下方の左右のマスを床としているが、異なる方向に走査した場合には下側に限定されない。 The temperature at the face detection position (the mass where the human body is detected) shown in FIG. 10a becomes the face surface temperature. In general, since it is considered that the ambient temperature of a person is close to the clothing temperature, as shown in FIG. 10B, in the imaging result of the temperature detection means 27, the temperature of the left and right squares below the face detection position (the square where the human body is detected) Can be regarded as the bed temperature (in FIG. 10b, expressed as a mass from which the temperature is extracted). Since the image pickup means 26 and the temperature detection means 27 of the present embodiment are rotated and scanned in the horizontal direction, the left and right squares below the face detected square are used as the floor, but when scanning in different directions. Is not limited to the lower side.
もし、顔検出位置が撮像結果の最下段のマスとなった場合には、そのマスの左右の温度を床温度とする。 If the face detection position is the lowest square of the imaging result, the left and right temperatures of the square are set as the floor temperature.
また、検出した床温度が所定の温度となるよう、設定温度をシフトさせる。検出した床温度の目標温度となる所定の温度は、リモコンで在室者が設定しても良く、予め所定の温度を機器制御部が備えていても良い。 Further, the set temperature is shifted so that the detected floor temperature becomes a predetermined temperature. The predetermined temperature that becomes the target temperature of the detected floor temperature may be set by a person in the room with a remote controller, or the device controller may have a predetermined temperature in advance.
空調温度・風向処理部６は、上記で求めた床温度を空調の制御温度として温度・風量・風向の空調制御をおこなう。 The air-conditioning temperature / wind direction processing unit 6 performs air-conditioning control of the temperature / air volume / wind direction using the floor temperature obtained above as the air-conditioning control temperature.
図１１は、温度分布生成・判定部５と空調温度・風向処理部６がマイクロコンピュータのプログラムで実現される場合の、上述の処理のフロー図である。 FIG. 11 is a flowchart of the above-described processing when the temperature distribution generation / determination unit 5 and the air conditioning temperature / wind direction processing unit 6 are realized by a program of a microcomputer.
上述のとおり、まず、撮像手段２６と温度検出手段２７を並行動作して撮像画像と温度分布画像を取得し（Ｓ２０１）、つぎに、撮像手段２６の撮像画像に顔検出処理を適用して顔検出をおこない、撮像画像上の顔位置を算出する（Ｓ２０２）。そして、検出した撮像画像上の顔位置に対応する温度分布画像の顔位置を算出し（Ｓ２０３）、温度分布画像の顔位置の所定数のマスだけ下方のマスの左右のマスを床として温度を取得する（Ｓ２０４）。さらに、温度分布画像の顔位置の方向を算出する（Ｓ２０５）。そして、取得した床温度と顔位置の方向に基づいて空調の温度・風量・風向を制御する（Ｓ２０６）。 As described above, first, the imaging unit 26 and the temperature detection unit 27 are operated in parallel to acquire a captured image and a temperature distribution image (S201), and then face detection processing is applied to the captured image of the imaging unit 26 to perform face detection. Detection is performed and the face position on the captured image is calculated (S202). Then, the face position of the temperature distribution image corresponding to the detected face position on the picked-up image is calculated (S203), and the temperature is determined using the left and right squares of the lower square as the floor by a predetermined number of squares of the face position of the temperature distribution image. Obtain (S204). Further, the direction of the face position of the temperature distribution image is calculated (S205). Then, the temperature, air volume, and direction of the air conditioning are controlled based on the acquired floor temperature and the direction of the face position (S206).
検出するマスは、顔を検出したマスの下方の左右のマスとする。顔を検出したマスの下方の左右のマスを床として温度を検出することで、温度を検出するマス内に人体の一部が含まれることによる誤検出を防ぐことが可能となる。すなわち、検出するマスに人体の足が写り込むことにより、当該マスで検出する温度は、床の温度だけでなく、足の温度も含んだ温度となる。 The detected squares are the left and right squares below the square where the face is detected. By detecting the temperature using the left and right squares below the square where the face is detected as a floor, it is possible to prevent erroneous detection due to a part of the human body being included in the temperature-detecting square. That is, when a human foot appears in the detected mass, the temperature detected by the mass becomes a temperature including not only the floor temperature but also the foot temperature.
そこで、本実施例における空気調和機の室内機１は、空気吸込み口１７及び空気吹出し口１８を有する筐体ベース８と、筐体ベース８内に配置された室内熱交換器９と、室内熱交換器９の下流側に位置する送風ファン１０と、室内を左右方向に数分割したエリア（マス）の各エリアにおける撮像画像を取得する撮像手段２６と、室内を左右方向に数分割したエリアの各エリアにおける放射熱を検出する温度検出手段２７と、撮像手段２６が人の存在を検知したエリアの左右方向隣に位置するエリアにおける温度検出手段２７で検出した温度を用いて空調制御を行う制御手段７を備える。 Therefore, the indoor unit 1 of the air conditioner in the present embodiment includes a housing base 8 having an air inlet 17 and an air outlet 18, an indoor heat exchanger 9 disposed in the housing base 8, and indoor heat. The blower fan 10 located on the downstream side of the exchanger 9, the image pickup means 26 for acquiring the picked-up images in each area of the area (mass) divided into the room in the left-right direction, and the area divided into the room in the left-right direction Control for performing air-conditioning control using the temperature detection means 27 for detecting radiant heat in each area and the temperature detected by the temperature detection means 27 in the area located next to the left and right direction of the area where the imaging means 26 detects the presence of a person. Means 7 are provided.
ここで、撮像手段２６は、人の顔の位置を検出するため、より足元に近いエリアの床温度を検知するために、制御手段７は、撮像手段２６が人の存在を検知したエリアの奥行方向手前であって、左右方向隣に位置するエリアにおける温度検出手段２７で検出した温度を用いて空調制御を行う。つまり、顔を検出したエリア（マス）の下方（奥行方向手前）の左右のエリア（マス）を床温度とする。 Here, in order to detect the position of the person's face, the imaging unit 26 detects the floor temperature in an area closer to the feet, and in order to detect the floor temperature of the area, the control unit 7 determines the depth of the area in which the imaging unit 26 detects the presence of the person. Air conditioning control is performed using the temperature detected by the temperature detection means 27 in an area located immediately before the direction and adjacent to the left-right direction. That is, the left and right areas (mass) below the area (mass) in which the face is detected are set as the floor temperature.
本実施例によれば、より高い精度で温度を検出することが可能となる。そして、検出した床温度が所定の温度以上となった場合に、設定温度のシフト値を変更する。すなわち、検出した床温度が例えば３０℃以上となるまでは、在室者の設定した温度を例えば４℃高い側にシフトさせる。そして、検出した床温度が３０℃以上となったら、設定温度をシフトする程度を小さくする。設定温度をシフトする程度は、３０℃を１℃超える毎に１℃小さくするステップ変化でも良く、３０℃を１℃超える毎に１℃小さくするようなランプ変化でも良い。 According to the present embodiment, it is possible to detect the temperature with higher accuracy. When the detected floor temperature becomes equal to or higher than a predetermined temperature, the set temperature shift value is changed. That is, the temperature set by the occupant is shifted to the higher side by, for example, 4 ° C. until the detected floor temperature becomes, for example, 30 ° C. or higher. Then, when the detected bed temperature is 30 ° C. or higher, the degree to which the set temperature is shifted is reduced. The degree to which the set temperature is shifted may be a step change that decreases by 1 ° C. every 30 ° C. exceeding 1 ° C., or a lamp change that decreases 1 ° C. every 30 ° C. exceeding 1 ° C.
床温度が所定の温度以上となった場合に、設定温度をシフトする程度を小さくすることで、熱の供給が過剰になることを防ぎ、室温が過剰に高くなることを予防することが可能となり、快適性を維持することが可能となる。また、床が十分高い温度となった時点で設定温度をシフトする程度を小さくするので、消費電力量を低減することが可能となる。 When the floor temperature exceeds the specified temperature, it is possible to prevent the heat supply from becoming excessive and to prevent the room temperature from becoming excessively high by reducing the degree to which the set temperature is shifted. It becomes possible to maintain comfort. Further, since the degree to which the set temperature is shifted when the floor reaches a sufficiently high temperature is reduced, the power consumption can be reduced.
検出した室温が所定の温度以上となった場合に、設定温度をシフトする程度を小さくする。また、検出した室温が所定の温度に届かない期間中は、検出した温度が所定の温度に到達した場合より高い温度で設定温度をシフトする。 When the detected room temperature is equal to or higher than a predetermined temperature, the degree to which the set temperature is shifted is reduced. Further, during the period when the detected room temperature does not reach the predetermined temperature, the set temperature is shifted at a higher temperature than when the detected temperature reaches the predetermined temperature.
すなわち、例えば床温度を検出するマスがファンヒータで暖まっていても、室温が設定温度や設定温度に所定のシフトを加えた温度より低い場合は、高い温度で設定温度をシフトし、室温が設定温度や設定温度に所定のシフトを加えた温度に到達している場合は、設定温度に加えるシフトの程度を低くする。 That is, for example, even if the mass for detecting the floor temperature is warmed by the fan heater, if the room temperature is lower than the set temperature or a temperature obtained by adding a predetermined shift to the set temperature, the set temperature is shifted to a higher temperature and the room temperature is set. When the temperature or the set temperature is reached by adding a predetermined shift, the degree of shift applied to the set temperature is lowered.
これにより、過剰な暖房を防ぐことが可能となり、快適性の向上と消費電力量の低減が可能となる。また、床温度のみによる制御と比較し、室温が低いことによる寒さを感じることもなく、高い快適性を維持することが可能となる。 Thereby, excessive heating can be prevented, and comfort can be improved and power consumption can be reduced. In addition, it is possible to maintain high comfort without feeling cold due to low room temperature as compared with control based on floor temperature alone.
また、顔検出位置から人の方向を算出し、送風ファン１０と左右風向板を駆動して空調風の風量と風向を制御するようにしてもよい。すなわち、送風ファン１０の吹出し風路に設けた左右風向板１３と、送風ファン１０の吹出し風路に設けた上下風向板１４と、を備え、制御手段７は、撮像手段２６が人の存在を検知したエリアの奥行方向手前に位置するエリアに応じて左右風向板１３及び上下風向板１４を制御する。つまり、撮像手段２６が人の存在を検知したエリアの奥行方向手前に位置するエリアに風が届くように左右風向板１３及び上下風向板１４を制御する。このような本実施例によれば、人の足元に風を届け、床を暖めることができる。 Further, the direction of the person may be calculated from the face detection position, and the air blower 10 and the left and right wind direction plates may be driven to control the air volume and the wind direction of the conditioned air. That is, the control unit 7 includes a left and right wind direction plate 13 provided in the blowing air path of the blower fan 10 and a vertical wind direction plate 14 provided in the blowing air path of the blower fan 10. The left and right wind direction plates 13 and the up and down wind direction plates 14 are controlled in accordance with the area located in the depth direction of the detected area. That is, the left and right wind direction plates 13 and the upper and lower wind direction plates 14 are controlled so that the wind reaches an area located in front of the depth direction of the area where the imaging means 26 detects the presence of a person. According to such a present Example, a wind can be delivered to a person's step and a floor can be warmed.
シフト値は、設定温度に対してステップアップ・ステップダウンして加味される。すなわち、例えば設定温度２３度の暖房時に設定温度を４℃シフトさせる場合、一度に４℃シフトするのではなく、１分あたり１℃シフトさせる。床の温度が所定の温度より高くなり、シフト値を小さくする場合も、一度にシフト値を変えるのではなく、１０分かけて０．５℃下げるようにシフトさせる。 The shift value is added by stepping up and down with respect to the set temperature. That is, for example, when the set temperature is shifted by 4 ° C. during heating at the set temperature of 23 ° C., it is not shifted by 4 ° C. at a time but by 1 ° C. per minute. Even when the floor temperature becomes higher than the predetermined temperature and the shift value is decreased, the shift value is not changed at a time but is shifted so as to decrease by 0.5 ° C. over 10 minutes.
これにより、設定温度が下がることによるサーモオフの発生を低減することが可能となり、暖房を断続させずに連続して運転させることが可能となり、快適性を維持することが可能となる。 As a result, it is possible to reduce the occurrence of thermo-off due to a decrease in the set temperature, and it is possible to continuously operate without interrupting heating, and it is possible to maintain comfort.
検出した床の温度が所定の温度となるよう、設定温度、風向、風速などの制御パラメータを制御することで、暖房時に対流だけでなく、伝導による熱の伝達を行うことが可能となる。すなわち、空気温度だけに基づいた制御とした場合では、床が冷たくても吸込み温度が高い場合はサーモオフしてしまう危険性があった。床温度を検出し、床温度を基準に空調することで、十分に足元を温められる暖房運転が可能となる。 By controlling the control parameters such as the set temperature, the wind direction, and the wind speed so that the detected floor temperature becomes a predetermined temperature, it becomes possible to transfer not only convection but also conduction by heat during heating. That is, when the control is based only on the air temperature, there is a risk that the thermo-off may occur if the suction temperature is high even if the floor is cold. By detecting the floor temperature and performing air conditioning based on the floor temperature, a heating operation that can sufficiently warm the feet is possible.
設定温度にシフト値を加算する方法について述べてきたが、設定温度に加算せず、圧縮機回転数、最大電流量、吹出し空気温度、室内熱交換器温度で床温度に基づいた空調を行っても良い。 Although the method of adding the shift value to the set temperature has been described, air conditioning based on the floor temperature is performed at the compressor speed, maximum current, blowing air temperature, and indoor heat exchanger temperature without adding to the set temperature. Also good.
すなわち、床温度が十分に高くなったら、圧縮機の最高回転数を下げる、圧縮機の回転数を所定の比率で下げる、最大電流量を下げる、吹出し空気温度を下げる、室内熱交換器温度を下げるなど、設定温以外のパラメータをシフトすることで、過大な熱量を室内に供給する危険性を低減し、暖かい足元による高い快適性を実現することが可能となる。 That is, when the floor temperature is sufficiently high, the maximum number of revolutions of the compressor is reduced, the number of revolutions of the compressor is reduced by a predetermined ratio, the maximum amount of current is lowered, the temperature of the blown air is lowered, and the temperature of the indoor heat exchanger is reduced. By shifting parameters other than the set temperature, such as lowering, it is possible to reduce the risk of supplying an excessive amount of heat into the room, and to realize high comfort with warm feet.
人体を検出し、人体の足元の左右のマスの温度を検出するため、人体が移動した場合には、人体が移動した先で改めて足元の温度を検出し、足元の温度に基づき設定温度のシフト値を制御する。 In order to detect the human body and the temperature of the left and right masses at the foot of the human body, when the human body moves, the temperature of the foot is detected again when the human body moves, and the set temperature shifts based on the temperature of the foot Control the value.
人体が移動する度に温度を検出する部分を更新するが、滞在時間や滞在頻度など、時間に関するパラメータで重みづけし、歩いている人を検出した場合など滞在時間や滞在頻度の低い場合は、より滞在時間や滞在頻度の高い方向を温度検出の対象とする。すなわち、本実施例における空気調和機の室内機１は、空気吸込み口１７及び空気吹出し口１８を有する筐体ベース８と、筐体ベース８内に配置された室内熱交換器９と、室内熱交換器９の下流側に位置する送風ファン１０と、室内を数分割したエリア（マス）の各エリアにおける撮像画像を取得する撮像手段２６と、室内を数分割したエリアの各エリアにおける放射熱を検出する温度検出手段２７と、撮像手段２６が設定時間内に複数のエリアで人を検知した場合、温度検出手段２７で検出した各エリアにおける温度に人の滞在時間に応じた値を重み付けした値を用いて空調制御を行う制御手段７を備える。 The temperature detection part is updated every time the human body moves, but weights are added with time parameters such as stay time and stay frequency, and if the stay time or stay frequency is low, such as when a walking person is detected, The direction in which the stay time and stay frequency are higher is the target of temperature detection. That is, the indoor unit 1 of the air conditioner in the present embodiment includes a housing base 8 having an air inlet 17 and an air outlet 18, an indoor heat exchanger 9 disposed in the housing base 8, and indoor heat. The blower fan 10 located on the downstream side of the exchanger 9, the image pickup means 26 for acquiring the picked-up images in each area of the area (mass) divided into several rooms, and the radiant heat in each area of the areas divided into several rooms When the temperature detecting means 27 to detect and the imaging means 26 detect a person in a plurality of areas within a set time, a value obtained by weighting the temperature in each area detected by the temperature detecting means 27 with a value corresponding to the person's stay time The control means 7 which performs air-conditioning control using is provided.
本実施例によれば、時間に関するパラメータで重み付けすることで、より高い精度で在室者の足元に暖気を供給することが可能となり、より高い快適性を実現することが可能となる。さらに、時間に関するパラメータで重みづけすることで、より高い精度で在室者の足元に暖気を供給することが可能となることで、より早く足元の温度が高くなり、より早くシフト値を低くすることが可能となり、より早く消費電力量を低減することが可能となる。 According to the present embodiment, it is possible to supply warm air to the feet of the occupants with higher accuracy by weighting with time-related parameters, and higher comfort can be realized. Furthermore, by weighting with time-related parameters, it becomes possible to supply warm air to the feet of occupants with higher accuracy, so that the temperature at the feet increases faster and the shift value decreases earlier. This makes it possible to reduce power consumption more quickly.
温度を検出するマスは、顔を検出したマスの所定値だけ下方の左右のマスとなる。顔を検出したマスと温度を検出するマスとの間のマスは、在室者の距離に応じて異なる。在室者が室内機から４ｍ以内の距離にいたら顔を検出したマスの３マス下の左右を床温度とする。在室者が室内機から４ｍより遠くにいる場合、顔を検出したマスより５マス下方のマスの左右のマスを床として温度を検出する。 The cells for detecting the temperature are left and right cells below the predetermined value of the cell from which the face is detected. The cell between the cell that detects the face and the cell that detects the temperature differs depending on the distance of the person in the room. When the occupant is within a distance of 4 m from the indoor unit, the floor temperature is set to the right and left three squares below the square where the face is detected. When the occupant is further than 4 m from the indoor unit, the temperature is detected using the left and right squares below the square where the face is detected as the floor.
検出する床の温度変化の推移から、シフト値を変更しても良い。すなわち、床の温度変化の推移は床の材質に起因し、床の材質は床の比熱や熱伝導率に関連する。床の比熱が小さく熱伝導率が高い畳の場合、床の温度は相対的に早く、小さな熱量で変化するため、設定温度のシフト値を小さくしても所定の床温度に到達させることが可能となる。その逆に、コンクリートの打ちっぱなしなど比熱が大きく熱伝導率も小さい場合、床の温度変化は小さくなる。さらに、比熱が小さく熱伝導率が高い床の場合、在室者の歩行時に床の冷たさを感じることが少なく、床温度が低い場合にも冷たさによる不快を感じにくく、設定温度のシフト値を小さくしても不快感は小さい。 You may change a shift value from transition of the temperature change of the floor to detect. That is, the transition of the floor temperature change is caused by the floor material, and the floor material is related to the specific heat and thermal conductivity of the floor. In the case of tatami mats with low specific heat of the floor and high thermal conductivity, the floor temperature is relatively fast and changes with a small amount of heat, so it is possible to reach the predetermined floor temperature even if the set temperature shift value is reduced. It becomes. Conversely, if the specific heat is large and the thermal conductivity is small, such as when concrete is left behind, the temperature change of the floor is small. Furthermore, in the case of floors with low specific heat and high thermal conductivity, the floor is less likely to feel cold when walking, and even when the floor temperature is low, it is difficult to feel discomfort due to the cold, and the set temperature shift value Even if it is made small, discomfort is small.
風向は、優先する在室者の方向のみとしても良い。また、全ての在室者の範囲内をスイングしても良い。また、全ての在室者の範囲内をスイングし、体感温度の低い在室者や入室からの時間が最も短い人の方向で一定時間スイングを停止して暖気を優先的に供給しても良い。これにより、在室者間の体感温度の差を低減することか可能となる。 The wind direction may be only the direction of the preferred occupant. Moreover, you may swing within the range of all the occupants. In addition, it may swing within the range of all the occupants, and the warm air may be preferentially supplied by stopping the swing for a certain period of time in the direction of the occupants having a low sensible temperature or the person having the shortest time since entering the room. . Thereby, it becomes possible to reduce the difference in the sensible temperature between the occupants.
本実施例は、室内に複数人が居る場合の例である。撮像画像により、それぞれの顔位置を検出して、各人の着衣温度と顔の方向を求める。そして、各人の着衣温度の平均値を空調の制御温度とし、最も着衣温度の高い人に向けて空調風を向けるか、または、最も着衣温度の高い人が空調風の送風時間が長くなるように風向板を制御する。図１２にその処理フローをしめす。 This embodiment is an example where there are a plurality of people in the room. Each face position is detected from the captured image, and the clothing temperature and face direction of each person are obtained. Then, let the average value of each person's clothing temperature be the control temperature of the air conditioning, and direct the conditioned air toward the person with the highest clothing temperature, or let the person with the highest clothing temperature have longer air-conditioning air blowing time Control the wind direction plate. FIG. 12 shows the processing flow.
図１２のフロー図にしめす本実施例は、図１１のフロー図のＳ２０２〜Ｓ２０５の処理を、Ｓ２０１で取得した撮像画像から顔検出した人数分繰り返し（Ｓ２０７）、顔検出した人の着衣温度の平均値を求め（Ｓ２０８）、着衣温度が最も高い人の顔位置の方向を求め（Ｓ２０９）、着衣温度の平均値と着衣温度が最も高い人の顔位置の方向に基づいて、空調の温度・風量・風向を制御する（Ｓ２１０）ようにした。 In the present embodiment shown in the flowchart of FIG. 12, the processes of S202 to S205 in the flowchart of FIG. 11 are repeated for the number of people whose faces are detected from the captured image acquired in S201 (S207). The average value is obtained (S208), the direction of the face position of the person with the highest clothing temperature is obtained (S209), and the air conditioner temperature and the direction of the face position of the person with the highest clothing temperature are obtained. The air volume and direction were controlled (S210).
複数人検出した場合は、最も近くにいる人を、暖房の対象とする。最も近くにいる人を対象とすることで、最も近くにいる人の足元に暖気を供給することになる。すなわち、本実施例における空気調和機の室内機１は、空気吸込み口１７及び空気吹出し口１８を有する筐体ベース８と、筐体ベース８内に配置された室内熱交換器９と、室内熱交換器９の下流側に位置する送風ファン１０と、送風ファン１０の吹出し風路に設けた左右風向板１３と、送風ファン１０の吹出し風路に設けた上下風向板１４と、室内を左右方向に数分割したエリア（マス）の各エリアにおける撮像画像を取得する撮像手段２６と、室内を左右方向に数分割したエリアの各エリアにおける放射熱を検出する温度検出手段２７と、撮像手段２６が人の存在を検知したエリアに応じた温度検出手段２７で検出した温度を用いて空調制御を行う制御手段７を備え、制御手段７は、撮像手段２６が複数のエリアで人を検知した場合、複数のエリアのうち空気調和機の室内機に最も近いエリアに応じて左右風向板１３及び上下風向板１４を制御する。つまり、人を検知した複数のエリアのうち空気調和機の室内機に最も近いエリアに風が届くように左右風向板１３及び上下風向板１４を制御する。 When a plurality of people are detected, the person who is closest is the target of heating. By targeting the person who is closest, the warm air is supplied to the feet of the person who is closest. That is, the indoor unit 1 of the air conditioner in the present embodiment includes a housing base 8 having an air inlet 17 and an air outlet 18, an indoor heat exchanger 9 disposed in the housing base 8, and indoor heat. The blower fan 10 located on the downstream side of the exchanger 9, the left and right wind direction plates 13 provided in the blowout air path of the blower fan 10, the up and down wind direction plate 14 provided in the blowout air path of the blower fan 10, and the left and right direction in the room An imaging unit 26 that acquires captured images in each area of the area (mass) divided into several areas, a temperature detection unit 27 that detects radiant heat in each area of the area divided into several parts in the left-right direction, and an imaging unit 26 The control means 7 performs air-conditioning control using the temperature detected by the temperature detection means 27 corresponding to the area where the presence of a person is detected. When the imaging means 26 detects a person in a plurality of areas, Multiple It controls the vertical louvers 13 and horizontal flaps 14 in accordance with the closest area to the indoor unit of the air conditioner of the area. In other words, the left and right wind direction plates 13 and the up and down wind direction plates 14 are controlled so that the wind reaches the area closest to the indoor unit of the air conditioner among the plurality of areas where the person is detected.
本実施例によれば、最も近くにいる人以外には、より手前側に供給された暖気が足元に届くことになる。すなわち、最も近くの人を基準とすることで、暖気が顔に当たることによる不快感を避けることが可能となり、快適性を維持することが可能となる。 According to the present embodiment, the warm air supplied to the near side reaches the feet of the person other than the closest person. That is, by using the closest person as a reference, it is possible to avoid discomfort due to warm air hitting the face, and it is possible to maintain comfort.
撮像手段２６が人の存在を検知したエリアに応じた温度検出手段２７で検出した温度には、人の存在を検知したエリアに加え、人の存在を検知したエリアの手前のエリアにおける床温度が含まれる。なお、最も近くにいる人にも暖気が顔に当たることを防ぐために、人の存在を検知したエリアの手前のエリアに風が届くよう左右風向板１３及び上下風向板１４を制御することが望ましい。 The temperature detected by the temperature detecting means 27 corresponding to the area where the imaging means 26 detects the presence of a person includes the floor temperature in the area in front of the area where the presence of the person is detected in addition to the area where the presence of the person is detected. included. In order to prevent warm air from hitting the person who is closest, it is desirable to control the left and right wind direction plates 13 and 14 so that the wind reaches the area in front of the area where the presence of the person is detected.
また、在室者をトラッキングし、長時間滞在している人を空調の対象としても良い。すなわち、歩いているなど同じ位置に短時間しかいない在室者に対して暖気を供給しても足元が温まる前に移動してしまう可能性がある。一方、長時間滞在している在室者は、短時間滞在している人に比べて、同じ位置に滞在する可能性が高いと予想することができる。 In addition, it is possible to track the occupants and set the person who stays for a long time as the target of air conditioning. That is, even if warm air is supplied to a person who is in the same position for a short time, such as walking, there is a possibility that the feet will move before warming up. On the other hand, a resident who stays for a long time can be expected to be more likely to stay at the same position than a person who stays for a short time.
すなわち、本実施例における空気調和機の室内機１は、空気吸込み口１７及び空気吹出し口１８を有する筐体ベース８と、筐体ベース８内に配置された室内熱交換器９と、室内熱交換器９の下流側に位置する送風ファン１０と、室内を左右方向に数分割したエリア（マス）の各エリアにおける撮像画像を取得する撮像手段２６と、室内を左右方向に数分割したエリアの各エリアにおける放射熱を検出する温度検出手段２７と、撮像手段２６が複数のエリアで人を検知した場合、人の滞在時間が長いエリアにおける温度検出手段２７で検出した温度を用いて空調制御を行う制御手段７を備える。 That is, the indoor unit 1 of the air conditioner in the present embodiment includes a housing base 8 having an air inlet 17 and an air outlet 18, an indoor heat exchanger 9 disposed in the housing base 8, and indoor heat. The blower fan 10 located on the downstream side of the exchanger 9, the image pickup means 26 for acquiring the picked-up images in each area of the area (mass) divided into the room in the left-right direction, and the area divided into the room in the left-right direction When the temperature detection means 27 for detecting radiant heat in each area and the imaging means 26 detect a person in a plurality of areas, air conditioning control is performed using the temperature detected by the temperature detection means 27 in the area where the person stays long. The control means 7 to perform is provided.
本実施例によれば、長時間滞在している在室者を基準とすることで、短時間滞在している人の足元を温める続けることなく、人が長時間滞在している在室者の足元を暖かく維持することが可能となる。なお、短時間滞在している人が所定の時間滞在し続けることで、長時間滞在している人と判断が更新される。 According to the present embodiment, the resident who is staying for a long time can keep the feet of the person who is staying for a short time from warming up. It is possible to keep the feet warm. Note that a person who stays for a short time continues to stay for a predetermined time, so that the determination that the person stays for a long time is updated.
さらに、本実施例における空気調和機の室内機１は、送風ファン１０の吹出し風路に設けた左右風向板１３と、送風ファン１０の吹出し風路に設けた上下風向板１４を備え、制御手段７は、撮像手段２６が設定時間内に複数のエリアで人を検知した場合、人の滞在時間が長いエリアに応じて左右風向板１３及び上下風向板１４を制御する。 Furthermore, the indoor unit 1 of the air conditioner in the present embodiment includes a left and right wind direction plate 13 provided in the blowout air passage of the blower fan 10 and a vertical wind direction plate 14 provided in the blowout air passage of the blower fan 10, and control means 7. When the imaging means 26 detects a person in a plurality of areas within the set time, the left and right wind direction plates 13 and the vertical wind direction plate 14 are controlled according to the area where the person's stay time is long.
また、移動量の多い人より移動量の小さな人を優先して床温度を検出し、暖気を供給しても良い。すなわち、移動量の多い人（短時間のみ同じエリアに滞在する人）の足元よりも移動量の少ない人の足元により多くの暖気を供給する。これにより、移動する人の移動先毎に暖気を供給し続けるのではなく、移動量が少なく同じ場所に滞在する人の足元に優先して暖めることが可能となり、効率的に暖気を床の温度上昇に用いることが可能となる。 Also, warm air may be supplied by detecting the floor temperature in preference to a person with a small amount of movement over a person with a large amount of movement. That is, more warm air is supplied to the feet of people with a small amount of movement than those of people with a large amount of movement (people who stay in the same area only for a short time). As a result, instead of continuing to supply warm air for each destination of a moving person, it becomes possible to preferentially warm the foot of a person who stays in the same place with a small amount of movement, and the warm air is efficiently transferred to the floor temperature. It can be used for ascent.
また、入室直後の在室者の足元の温度を高めることを優先して空調しても良い。すなわち、気温の低い屋外からの入室直後の在室者は、暖房された室内に長時間滞在している在室者と比較して、産熱量に対する放熱量が多く、体温は低くなっており、暖房の必要性はより高い。 In addition, air conditioning may be performed with priority given to increasing the temperature of the occupants immediately after entering the room. In other words, the occupants immediately after entering the room from the outside with a low temperature have a large amount of heat radiation with respect to the amount of heat produced and the body temperature is lower than the occupants who have stayed in the heated room for a long time. The need for heating is higher.
すなわち、本実施例における空気調和機の室内機１は、撮像手段２６が複数のエリアで人を検知した場合、撮像手段２６で検知された時間が最も短い人が位置するエリアに応じて左右風向板１３及び上下風向板１４を制御する制御手段７を備える。 That is, in the indoor unit 1 of the air conditioner according to the present embodiment, when the imaging unit 26 detects a person in a plurality of areas, the right and left wind directions according to the area where the person detected by the imaging unit 26 has the shortest time is located. The control means 7 which controls the board 13 and the up-and-down wind direction board 14 is provided.
本実施例によれば、入室直後の在室者を優先して空調することで、暖房を必要とする入室直後の在室者の快適性を上げることが可能となり、在室者間の快適性を均一化することが可能となる。入室直後の在室者を優先する程度、すなわち優先する時間や温度は、入室直後の在室者の滞在時間や外気温によって変化させても良い。 According to the present embodiment, it is possible to increase the comfort of the occupants immediately after entering the room requiring heating by preferentially air-conditioning the occupants immediately after entering the room. Can be made uniform. The degree of priority given to the occupants immediately after entering the room, that is, the priority time and temperature may be changed according to the stay time and the outside air temperature of the occupants immediately after entering the room.
また、体感温度の最も低い人の足元の温度が所定の温度になるよう、体感温度の最も低い人を優先して空調しても良い。すなわち、本実施例における空気調和機の室内機１は、撮像手段２６が複数のエリアで人を検知した場合、温度検出手段２７で検出された温度が最も低いエリアに応じて左右風向板１３及び上下風向板１４を制御する制御手段７を備える。 In addition, air conditioning may be performed with priority given to the person with the lowest sensation temperature so that the temperature at the feet of the person with the lowest sensation temperature becomes a predetermined temperature. That is, in the indoor unit 1 of the air conditioner in the present embodiment, when the imaging unit 26 detects a person in a plurality of areas, the left and right wind direction plates 13 and 13 The control means 7 which controls the up-and-down wind direction board 14 is provided.
室内にストーブや石油ファンヒータ、ハロゲンヒーターや暖炉、床暖房などによる温度ムラが有る場合、在室者の位置により体感温度は大きく異なる。また、在室者の代謝量や着衣量によっても体感温度は大きく異なる。体感温度の低い人の足元の温度が所定の温度になるよう、体感温度の最も低い人を優先して空調することで、代謝量が大きく体感温度の高い人に暖気を供給する危険性を低減することが可能となり、代謝量が小さく体感温度の低い人に暖気を供給し高い快適性を得ることが可能となる。 When the room has temperature unevenness due to a stove, oil fan heater, halogen heater, fireplace, floor heating, etc., the sensible temperature varies greatly depending on the position of the occupant. In addition, the temperature of sensation varies greatly depending on the amount of metabolism and the amount of clothes of people in the room. Reduces the risk of supplying warm air to people with a high metabolic rate and high air temperature by prioritizing the air with the lowest temperature so that the temperature at the feet of people with a low temperature is the specified temperature. It is possible to supply warm air to a person with a low metabolic rate and a low sensible temperature, and to obtain high comfort.
床温度を検出する人数は、一人でもよく、また複数人でも良い。すなわち、在室者が複数人いるときは、どちらか一方を優先して温度を検出し、その温度に基づいて空調しても良い。また、複数の在室者のそれぞれについて温度を検出し、最も大きなシフト値に基づいて空調しても良い。あるいは、複数の在室者のそれぞれについて温度を検出し、平均したシフト値をその部屋のシフト値としても良い。 The number of persons who detect the floor temperature may be one or more. That is, when there are a plurality of people in the room, the temperature may be detected with priority given to either one, and air conditioning may be performed based on the temperature. Further, the temperature may be detected for each of a plurality of people in the room, and air conditioning may be performed based on the largest shift value. Alternatively, the temperature may be detected for each of a plurality of people in the room, and the average shift value may be used as the shift value for the room.
上記の実施例では、撮像手段２６と温度検出手段２７を並行動作させて撮像をおこなう例を説明したが、空調する室内を静止状態と見なせる場合（人の移動を考慮しない場合等）には、図１２に示すように、撮像手段２６と温度検出手段２７により順に交互に撮像をおこなってもよい。 In the above-described embodiment, an example in which imaging is performed by operating the imaging unit 26 and the temperature detection unit 27 in parallel has been described. However, in a case where the air-conditioned room can be regarded as a stationary state (when the movement of a person is not considered), As shown in FIG. 12, the imaging unit 26 and the temperature detection unit 27 may alternately perform imaging in order.
詳しくは、まず、撮像手段により撮像画像を取得し（Ｓ２１１）、取得した撮像画像を基に顔検出処理をおこなって、撮像画像上の顔位置を算出する（Ｓ２１２）。そして、撮像画像上の顔位置から対応するサーモパイルの回動角度と顔の方向を算出する（Ｓ２１３）。つぎに、サーモパイルを算出した回動角度に駆動して温度を取得し（Ｓ２１４）、顔位置のひとつ下を着衣として、着衣温度を取得する（Ｓ２１５）。そして、取得した着衣温度と顔位置の方向に基づいて空調の温度・風量・風向を制御する（Ｓ２１６）。 Specifically, first, a captured image is acquired by the imaging unit (S211), face detection processing is performed based on the acquired captured image, and a face position on the captured image is calculated (S212). Then, the rotation angle and the face direction of the corresponding thermopile are calculated from the face position on the captured image (S213). Next, the thermopile is driven to the calculated rotation angle to obtain the temperature (S214), and the clothing temperature is obtained with the clothing positioned one below the face position (S215). Then, the temperature, air volume, and wind direction of the air conditioner are controlled based on the acquired clothing temperature and the direction of the face position (S216).
また、上記の実施例では、顔検出処理を撮像画像についておこなっているが、温度分布画像の特定の温度より低い領域に対応する撮像画像の領域のデータをマスク処理するようにしてもよい。これによれば、顔検出する領域を限定できるので、データ処理量を低減することができる。 In the above embodiment, the face detection process is performed on the captured image. However, the data of the region of the captured image corresponding to the region lower than the specific temperature of the temperature distribution image may be masked. According to this, since the area for face detection can be limited, the amount of data processing can be reduced.
