Description

この発明は、空気調和機に関する。 The present invention relates to an air conditioner.

例えば、壁掛け式の空気調和機では、通常室内機は部屋の高所の壁に据付られる。しかし、室内機が据付られる壁における左右の位置は、様々である。壁の左右方向の略中央に据付られる場合もあるし、室内機から見て右側又は左側の壁に接近して据付られる場合もある。以下、この明細書では、部屋の左右方向とは、室内機から見た左右方向と定義する。 For example, in a wall-mounted air conditioner, an indoor unit is usually installed on a high wall of a room. However, the left and right positions on the wall where the indoor unit is installed are various. It may be installed at the approximate center in the left-right direction of the wall, or may be installed close to the right or left wall as viewed from the indoor unit. Hereinafter, in this specification, the left-right direction of the room is defined as the left-right direction viewed from the indoor unit.

室内機が壁の左右方向の略中央に据付られる場合は、室内機から吹き出される空気の方向による部屋への影響は殆どないが、室内機から見て右側又は左側の壁に接近して据付られる場合は、接近している右側又は左側の壁に向かって室内機から空気が吹き出されると、居住空間の空調が不足するため、空調効率が悪化し快適性が損なわれる。また、直接室内機から空気が吹き付けられる壁に汚れ・はがれ等が発生しやすい。 When the indoor unit is installed at the approximate center in the left-right direction of the wall, the direction of the air blown from the indoor unit has little effect on the room, but it is installed close to the right or left wall as viewed from the indoor unit. If air is blown from the indoor unit toward the approaching right or left wall, the air conditioning in the living space is insufficient, and the air conditioning efficiency deteriorates and the comfort is impaired. In addition, the wall to which air is directly blown from the indoor unit is likely to be contaminated and peeled.

そこで、使用者が、リモコンの設置位置設定スイッチにより室内機の壁における設置位置、「中央設置」、「左設置」、「右設置」を選択し、「中央設置」が選択されたときは、左右風向羽根の風向を、設置壁に対して中央を中心に左右７５度ずつ１５０度左右にスイングするように制御する。また、「左設置」が選択された時は、左右風向羽根の風向を、中央から右方向７５度間のみを、左右にスイングするように制御する。また、「右設置」が選択された時は、左右羽根の風向を、中央から左方向７５度間のみを、左右にスイングするように制御するようにした空気調和機が提案されている（例えば、特許文献１参照）。
特開２００２−１０６９１９号公報 Therefore, when the user selects the installation position on the wall of the indoor unit, “center installation”, “left installation”, “right installation” with the remote controller installation position setting switch, and “central installation” is selected, The wind direction of the left and right wind direction blades is controlled to swing left and right by 150 degrees about the center with respect to the installation wall. Also, when “left installation” is selected, the wind direction of the left and right wind direction blades is controlled to swing left and right only within 75 degrees from the center to the right. In addition, when “right installation” is selected, an air conditioner has been proposed in which the wind direction of the left and right blades is controlled to swing left and right only within 75 degrees leftward from the center (for example, , See Patent Document 1).

しかしながら、上記特許文献１は、空気調和機の使用者が室内機の設置位置の設定を行う必要があり、使用者にとっては不便なものであった。尚、上記特許文献１には記載されていないが、空気調和機の据付業者が室内機の設置位置の入力を行う場合もある。 However, Patent Document 1 described above is inconvenient for the user because the user of the air conditioner needs to set the installation position of the indoor unit. In addition, although not described in the said patent document 1, the installation contractor of an air conditioner may input the installation position of an indoor unit.

以上のように、従来の空気調和機は、据付業者又は使用者が据付時に室内機の設置位置の入力をリモコン等（室内機本体による場合もある）により行う必要があり、不便であると共に室内機の設置位置の入力を忘れた場合は、空調効率が悪化し快適性が損なわれる。また、直接室内機から空気が吹き付けられる壁に汚れ・はがれ等が発生しやすいという課題があった。 As described above, the conventional air conditioner needs to input the installation position of the indoor unit by a remote controller or the like (sometimes depending on the indoor unit main body) at the time of installation by the installer or user, which is inconvenient and indoors. If you forget to enter the installation position of the machine, air conditioning efficiency will deteriorate and comfort will be impaired. In addition, there is a problem that dirt, peeling, and the like are likely to occur on the wall directly blown from the indoor unit.

この発明は、上記のような課題を解決するためになされたもので、据え付け時に作業者又は使用者が室内機の据付位置の設定をしなくても、自動的に室内機の据付位置の設定を行うことができる空気調和機を提供する。 The present invention has been made to solve the above-described problems. Even when an operator or a user does not set the installation position of the indoor unit during installation, the indoor unit installation position is automatically set. An air conditioner capable of performing the above is provided.

実施の形態１．
先ず、本実施の形態の概要を説明する。空気調和機（室内機）は、温度検出対象範囲を走査しながら温度を検出する可動式赤外線センサを備え、可動式赤外線センサにより熱源検知を行って人や発熱機器の存在を検知して、快適な制御を行うようにしている。 Embodiment 1 FIG.
First, an outline of the present embodiment will be described. The air conditioner (indoor unit) is equipped with a movable infrared sensor that detects the temperature while scanning the temperature detection target range, and detects the presence of people and heat-generating equipment by detecting the heat source using the movable infrared sensor. To perform proper control.

通常室内機は部屋の高所の壁に据付られるが、室内機が据付られる壁における左右の位置は、様々である。壁の左右方向の略中央に据付られる場合もあるし、室内機から見て右側又は左側の壁に接近して据付られる場合もある。 Usually, the indoor unit is installed on a wall at a high place in the room, but the left and right positions on the wall on which the indoor unit is installed are various. It may be installed at the approximate center in the left-right direction of the wall, or may be installed close to the right or left wall as viewed from the indoor unit.

本実施の形態の空気調和機は、起動時に可動式赤外線センサを利用して、空気調和機自身が据付られる壁における左右の位置を判断して、それに合わせて自動的に吹出し風向（左右フラップ）等の設定を行うものである。それにより、空調効率が悪化し快適性が損なわれることを抑制すると共に、直接室内機から空気が吹き付けられる壁に汚れ・はがれ等が発生することがないようにするものである。 The air conditioner of this embodiment uses a movable infrared sensor at the time of start-up to determine the left and right positions on the wall where the air conditioner itself is installed, and automatically blows out the wind direction (left and right flaps) accordingly. Etc. are set. Thus, the air conditioning efficiency is prevented from deteriorating and the comfort is impaired, and the wall to which air is directly blown from the indoor unit is prevented from being contaminated or peeled off.

図１乃至図３により、空気調和機１００（室内機）の全体構成を説明する。図１、図２共に、空気調和機１００の外観斜視図であるが、見る角度が異なる点と、図１は上下フラップ４３（上下風向制御板、左右に２個）が閉じているのに対して、図２は上下フラップ４３が開き奥の左右フラップ４４（左右風向制御板、多数）が見えている点とが異なる。 The overall configuration of the air conditioner 100 (indoor unit) will be described with reference to FIGS. 1 to 3. 1 and FIG. 2 are external perspective views of the air conditioner 100, but the view angle is different, and FIG. 1 shows that the upper and lower flaps 43 (up and down wind direction control plates, two on the left and right) are closed. FIG. 2 is different from FIG. 2 in that the upper and lower flaps 43 are open and the left and right flaps 44 (left and right wind direction control plates, many) are visible.

図１に示すように、空気調和機１００（室内機）は、略箱状の室内機筺体４０（本体と定義する）の上面に部屋の空気を吸い込む吸込口４１が形成されている。 As shown in FIG. 1, the air conditioner 100 (indoor unit) has a suction port 41 for sucking room air on the upper surface of a substantially box-shaped indoor unit housing 40 (defined as a main body).

また、前面の下部に調和空気を吹き出す吹出口４２が形成されていて、吹出口４２には吹き出し風の風向を制御する上下フラップ４３と、左右フラップ４４とが設けられる。上下フラップ４３は吹き出し風の上下風向を制御し、左右フラップ４４は吹き出し風の左右風向を制御する。 Moreover, the blower outlet 42 which blows off conditioned air is formed in the lower part of the front, and the blower outlet 42 is provided with the upper and lower flaps 43 and the left and right flaps 44 for controlling the direction of the blown air. The upper and lower flaps 43 control the up and down direction of the blowing air, and the left and right flaps 44 control the left and right direction of the blowing air.

室内機筺体４０の前面の下部で、吹出口４２の上に、可動式赤外線センサ３（赤外線センサの一例）が設けられている。可動式赤外線センサ３は、俯角約２４．５度の角度で下向きに取り付けられている。俯角とは、可動式赤外線センサ３の中心軸と水平線とがなす角度である。別の言い方をすると、可動式赤外線センサ３は、水平線に対して約２４．５度の角度で下向きに取り付けられている。 A movable infrared sensor 3 (an example of an infrared sensor) is provided on the outlet 42 in the lower part of the front surface of the indoor unit housing 40. The movable infrared sensor 3 is attached downward at an depression angle of about 24.5 degrees. The depression angle is an angle formed by the central axis of the movable infrared sensor 3 and a horizontal line. In other words, the movable infrared sensor 3 is mounted downward at an angle of about 24.5 degrees with respect to the horizon.

図３に示すように、空気調和機１００（室内機）は、内部に送風機４５を備え、該送風機４５を囲むように熱交換器４６が配置されている。 As shown in FIG. 3, the air conditioner 100 (indoor unit) includes a blower 45 inside, and a heat exchanger 46 is disposed so as to surround the blower 45.

熱交換器４６は、室外機（図示せず）に搭載された圧縮機等と接続されて冷凍サイクルを形成している。冷房運転時は蒸発器として、暖房運転時は凝縮器として動作する。 The heat exchanger 46 is connected to a compressor or the like mounted on an outdoor unit (not shown) to form a refrigeration cycle. It operates as an evaporator during cooling operation and as a condenser during heating operation.

吸込口４１から送風機４５により室内空気が吸い込まれ、熱交換器４６で冷凍サイクルの冷媒と熱交換を行い、送風機４５を通過して吹出口４２から室内へ吹き出される。 Room air is sucked in by the blower 45 from the suction port 41, heat exchange is performed with the refrigerant of the refrigeration cycle in the heat exchanger 46, passes through the blower 45, and is blown out into the room from the outlet 42.

吹出口４２では、上下フラップ４３と左右フラップ４４（図３では図示していない）とにより、上下方向及び左右方向の風向が制御される。図３は、上下フラップ４３が水平吹き出しの角度になっている。 At the air outlet 42, the vertical and horizontal flaps 43 and left and right flaps 44 (not shown in FIG. 3) control the vertical and horizontal wind directions. In FIG. 3, the upper and lower flaps 43 are at a horizontal blowing angle.

図４に示すように、可動式赤外線センサ３は、金属缶１内部に８個の受光素子（図示せず）を縦方向に一列に配列している。金属缶１の上面には、８個の受光素子に赤外線を通すためのレンズ製の窓（図示せず）が設けられている。各受光素子の配光視野角２は、縦方向７度、横方向８度である。尚、各受光素子の配光視野角２が、縦方向７度、横方向８度のものを示したが、縦方向７度、横方向８度に限定されるものではない。各受光素子の配光視野角２に応じて、受光素子の数は変化する。例えば、１個の受光素子の縦配光視野角と受光素子の数との積が一定になるようにすればよい。 As shown in FIG. 4, the movable infrared sensor 3 has eight light receiving elements (not shown) arranged in a row in the vertical direction inside the metal can 1. On the upper surface of the metal can 1, there are provided lens windows (not shown) for passing infrared rays through the eight light receiving elements. The light distribution viewing angle 2 of each light receiving element is 7 degrees in the vertical direction and 8 degrees in the horizontal direction. In addition, although the light distribution viewing angle 2 of each light receiving element showed 7 degrees of vertical directions and 8 degrees of horizontal directions, it is not limited to 7 degrees of vertical directions and 8 degrees of horizontal directions. The number of light receiving elements changes according to the light distribution viewing angle 2 of each light receiving element. For example, the product of the vertical light distribution viewing angle of one light receiving element and the number of light receiving elements may be made constant.

図５は、可動式赤外線センサ３付近を裏側（空気調和機１００の内部から）から見た斜視図である。図５に示すように、可動式赤外線センサ３は、筐体５内に収納されている。そして、筐体５の上方に可動式赤外線センサ３を駆動するステッピングモーター６が設けられる。筐体５と一体の取付部７が空気調和機１００の前面下部に固定されることにより、可動式赤外線センサ３が空気調和機１００に取り付けられる。可動式赤外線センサ３が空気調和機１００に取り付けられた状態では、ステッピングモーター６と筐体５は垂直である。そして、筐体５の内部で可動式赤外線センサ３が、俯角約２４．５度の角度で下向きに取り付けられている。 FIG. 5 is a perspective view of the vicinity of the movable infrared sensor 3 as seen from the back side (from the inside of the air conditioner 100). As shown in FIG. 5, the movable infrared sensor 3 is housed in the housing 5. A stepping motor 6 that drives the movable infrared sensor 3 is provided above the housing 5. The movable infrared sensor 3 is attached to the air conditioner 100 by fixing the attachment portion 7 integrated with the housing 5 to the lower front portion of the air conditioner 100. In a state where the movable infrared sensor 3 is attached to the air conditioner 100, the stepping motor 6 and the housing 5 are vertical. The movable infrared sensor 3 is attached to the inside of the housing 5 downward at an included angle of about 24.5 degrees.

可動式赤外線センサ３は、ステッピングモーター６により左右方向に所定角度範囲を回転駆動する（このような回転駆動をここでは、可動する、と表現する）が、図６に示すように右端端部（ａ）から中央部（ｂ）を経由して左端端部（ｃ）まで可動し、左端端部（ｃ）に来ると逆方向に反転して可動する。この動作を繰り返す。可動式赤外線センサ３は、部屋の温度検出対象範囲を左右に走査しながら温度検出対象の温度を検出する。 The movable infrared sensor 3 is rotationally driven by a stepping motor 6 within a predetermined angle range in the left-right direction (this rotational drive is expressed as movable here), but as shown in FIG. It moves from a) to the left end portion (c) via the central portion (b), and when it reaches the left end portion (c), it is reversed and moved in the reverse direction. This operation is repeated. The movable infrared sensor 3 detects the temperature of the temperature detection target while scanning the room temperature detection target range from side to side.

ここで、可動式赤外線センサ３による部屋の壁や床の熱画像データの取得方法について述べる。尚、可動式赤外線センサ３等の制御は、所定の動作がプログラムされたマイクロコンピュータによって行われる。所定の動作がプログラムされたマイクロコンピュータを制御部と定義する。以下の説明では、一々夫々の制御を制御部（所定の動作がプログラムされたマイクロコンピュータ）が行うという記載は省略する。 Here, the acquisition method of the thermal image data of the wall and floor of the room by the movable infrared sensor 3 will be described. The movable infrared sensor 3 and the like are controlled by a microcomputer programmed with a predetermined operation. A microcomputer programmed with a predetermined operation is defined as a control unit. In the following description, a description that each control is performed by the control unit (a microcomputer programmed with a predetermined operation) is omitted.

部屋の壁や床の熱画像データを取得する場合、可動式赤外線センサ３をステッピングモーター６により左右方向に可動し、ステッピングモーター６の可動角度（可動式赤外線センサ３の回転駆動角度）１．６度毎に各位置で可動式赤外線センサ３を所定時間（０．１〜０．２秒）停止させる。 When acquiring thermal image data of the wall or floor of the room, the movable infrared sensor 3 is moved in the left-right direction by the stepping motor 6, and the movable angle of the stepping motor 6 (the rotational drive angle of the movable infrared sensor 3) is 1.6. The movable infrared sensor 3 is stopped at each position every predetermined time for a predetermined time (0.1 to 0.2 seconds).

可動式赤外線センサ３を停止した後、所定時間（０．１〜０．２秒より短い時間）待ち、可動式赤外線センサ３の８個の受光素子の検出結果（熱画像データ）を取り込む。 After the movable infrared sensor 3 is stopped, it waits for a predetermined time (a time shorter than 0.1 to 0.2 seconds), and the detection results (thermal image data) of the eight light receiving elements of the movable infrared sensor 3 are captured.

可動式赤外線センサ３の検出結果を取り込み終了後、再びステッピングモーター６を駆動（可動角度１．６度）して後停止し、同様の動作により可動式赤外線センサ３の８個の受光素子の検出結果（熱画像データ）を取り込む。 After capturing the detection result of the movable infrared sensor 3, the stepping motor 6 is driven again (moving angle 1.6 degrees) and then stopped, and the eight light receiving elements of the movable infrared sensor 3 are detected by the same operation. Capture the results (thermal image data).

上記の動作を繰り返し行い、左右方向に９４箇所の可動式赤外線センサ３の検出結果をもとに検知エリア内の熱画像データを演算する。 The above operation is repeated, and thermal image data in the detection area is calculated based on the detection results of 94 movable infrared sensors 3 in the left-right direction.

ステッピングモーター６の可動角度１．６度毎に９４箇所で可動式赤外線センサ３を停止させて熱画像データを取り込むので、可動式赤外線センサ３の左右方向の可動範囲（左右方向に回転駆動する角度範囲）は、約１５０．４度である。 Since the movable infrared sensor 3 is stopped at 94 positions every 1.6 degrees of the movable angle of the stepping motor 6 and the thermal image data is captured, the movable range of the movable infrared sensor 3 in the horizontal direction (the angle for rotationally driving the horizontal direction) Range) is about 150.4 degrees.

尚、可動式赤外線センサ３をステッピングモーター６により左右方向に可動して部屋の壁や床の熱画像データを取得する場合、空気調和機１００の上下フラップ４３の向きは水平に固定する。そして、左右フラップ４４は、右側に最大に傾けた場合と、左側に最大に傾けた場合との二つのケースについて部屋の熱画像データを取得する。この点については、追って詳しく述べる。 When the movable infrared sensor 3 is moved in the left-right direction by the stepping motor 6 to acquire thermal image data of the wall or floor of the room, the direction of the upper and lower flaps 43 of the air conditioner 100 is fixed horizontally. The left and right flaps 44 acquire room thermal image data for two cases of tilting to the right and maximizing to the left. This point will be described in detail later.

図７は空気調和機１００を部屋の床面から１８００ｍｍの高さに据付けた状態で、８個の受光素子が縦に一列に配列された可動式赤外線センサ３の縦断面における縦配光視野角を示す。 FIG. 7 shows a vertical light distribution viewing angle in a vertical cross section of the movable infrared sensor 3 in which eight light receiving elements are arranged in a vertical row in a state where the air conditioner 100 is installed at a height of 1800 mm from the floor of the room. Indicates.

図７に示す角度７°は、１個の受光素子の縦配光視野角である。 The angle 7 ° shown in FIG. 7 is the vertical light distribution viewing angle of one light receiving element.

また、図７の角度３７．５°は、可動式赤外線センサ３の縦視野領域に入らない領域の空気調和機１００が取り付けられた壁からの角度を示す。可動式赤外線センサ３の俯角が０°であれば、この角度は、９０°−４（水平より下の受光素子の数）×７°（１個の受光素子の縦配光視野角）＝６２°になる。本実施の形態の可動式赤外線センサ３は、俯角が２４．５°であるから、６２°−２４．５°＝３７．５°になる。 Further, an angle 37.5 ° in FIG. 7 indicates an angle from a wall to which the air conditioner 100 in a region that does not enter the vertical field of view of the movable infrared sensor 3 is attached. If the depression angle of the movable infrared sensor 3 is 0 °, this angle is 90 ° −4 (number of light receiving elements below the horizontal) × 7 ° (vertical light distribution viewing angle of one light receiving element) = 62. It becomes °. Since the movable infrared sensor 3 of the present embodiment has a depression angle of 24.5 °, 62 ° -24.5 ° = 37.5 °.

図８は８畳相当の部屋で主婦１２が幼児１３を抱いている一生活シーンを可動式赤外線センサ３を左右方向に可動させながら得られた検出結果をもとに熱画像データとして演算した結果を示す。 FIG. 8 shows a result of calculation as thermal image data based on a detection result obtained by moving the movable infrared sensor 3 in the left-right direction in a living scene where the housewife 12 is holding the infant 13 in a room equivalent to 8 tatami mats. Indicates.

図８は季節が冬で、且つ天候が曇りの日に取得した熱画像データである。従って、窓１４の温度は、１０〜１５℃と低い。主婦１２と幼児１３の温度が最も高い。特に、主婦１２と幼児１３の上半身の温度は、２６〜３０℃である。このように、可動式赤外線センサ３を左右方向に可動させることにより、例えば、部屋の各部の温度情報を取得することができる。 FIG. 8 shows thermal image data acquired on a day when the season is winter and the weather is cloudy. Therefore, the temperature of the window 14 is as low as 10 to 15 ° C. Housewives 12 and infants 13 have the highest temperatures. In particular, the temperature of the upper body of the housewife 12 and the infant 13 is 26-30 ° C. Thus, by moving the movable infrared sensor 3 in the left-right direction, for example, temperature information of each part of the room can be acquired.

図９はある任意の大きさの部屋に空気調和機１００が設置されている様子を示す。空気調和機１００は、据付壁５０（破線のハッチング部分）に設置されている。据付壁５０の右側に、右側の壁１７がある。また、据付壁５０の左側に、左側の壁１６がある。また、据付壁５０の正面に、正面の壁１９がある。さらに、据付壁５０の下に床１８がある。 FIG. 9 shows a state where the air conditioner 100 is installed in a room of an arbitrary size.

The left wall 16 is on the left side of the installation wall 50. A front wall 19 is located in front of the installation wall 50. Further, there is a floor 18 under the installation wall 50.

図７に示す縦方向の配光視野角を持つ可動式赤外線センサ３を左右方向に９４カ所（角度１５０．４°）可動させることにより取得できる熱画像データの検知対象エリア領域は、空気調和機１００から見て右側の壁１７と、左側の壁１６と、正面の壁１９と、床１８とが主となる。 The detection area area of the thermal image data that can be acquired by moving the movable infrared sensor 3 having the vertical light distribution viewing angle shown in FIG. 7 in 94 positions (angle 150.4 °) in the left-right direction is an air conditioner The right wall 17, the left wall 16, the front wall 19, and the floor 18 as viewed from 100 are mainly used.

図１４は床面の１辺が３６００ｍｍの正方形（８畳相当）の部屋を２つ並べた１６畳相当の部屋の長手方向の壁の中央付近に空気調和機１００を設置した部屋空間に対し、３角法にて床面と壁面を展開した図である。 FIG. 14 shows a room space in which the air conditioner 100 is installed in the vicinity of the center of the longitudinal wall of a room corresponding to 16 tatami mats, in which two rooms of a square (equivalent to 8 tatami mats) each having a side of 3600 mm are arranged side by side. It is the figure which developed the floor surface and the wall surface by the triangle method.

図９と同様に取得する熱画像としての検知対象エリア領域は空気調和機１００から見て、右側の壁１７と、左側の壁１６と、正面の壁１９と、床１８となる。 Similar to FIG. 9, the detection target area area as a thermal image to be acquired is the right wall 17, the left wall 16, the front wall 19, and the floor 18 as viewed from the air conditioner 100.

図１１は図１４の空気調和機１００の据付条件にて熱画像データを取得する際の床面領域２２、壁面領域２０、床面と壁面との境界線領域２１の検知エリア領域を示す図である。空気調和機１００の据付け高さを１８００ｍｍとした場合（図７）に取得できる縦８素子＊横９４分解能から得られる７５２画素相当の熱画像における壁面領域２０と、床面領域２２と、床１８と壁面（右側の壁１７、左側の壁１６、正面の壁１９）との境界線領域２１とを示す。 Figure 11 is a diagram showing a detection area area border region 21 of the floor area 22, the wall surface area 20, the floor and the wall in acquiring thermal image data by installation conditions of the air conditioner 100 in FIG. 14 is there. When the installation height of the air conditioner 100 is 1800 mm (FIG. 7), the wall surface region 20, the floor surface region 22, and the floor 18 in the thermal image corresponding to 752 pixels obtained from 8 vertical elements * 94 horizontal resolutions that can be acquired. And a boundary region 21 between the wall surface (the right wall 17, the left wall 16, and the front wall 19).

空気調和機１００から見て手前側の床面領域２２を検知する検知素子は受光素子ａ〜ｃが支配的となる。また、壁面領域２０を検知する検知素子は受光素子ｅ〜ｈが主となる。 The light receiving elements a to c are dominant in the detection element that detects the floor surface region 22 on the near side when viewed from the air conditioner 100. In addition, the light receiving elements e to h are the main detecting elements for detecting the wall surface region 20.

そして、受光素子ｄ，ｅが左右角度と可動式赤外線センサ３の縦方向配光視野角（図７）の関係上、床１８と壁面（右側の壁１７、左側の壁１６、正面の壁１９）との境界線付近の境界線領域２１を検知することとなる。 The light receiving elements d and e have a floor 18 and a wall surface (the right wall 17, the left wall 16, and the front wall 19) because of the relationship between the left and right angles and the vertical light distribution viewing angle of the movable infrared sensor 3 (FIG. 7). ) Is detected near the boundary line 21).

従って、図１１において、取得される熱画像において床面領域２２は下部領域となり、壁面領域２０は上部領域となり、床１８と壁面（右側の壁１７、左側の壁１６、正面の壁１９）との境界線領域２１が、床面領域２２と壁面領域２０の間の位置付けとなる。 Accordingly, in FIG. 11, the floor area 22 is a lower area and the wall surface area 20 is an upper area in the acquired thermal image, and the floor 18 and the wall surfaces (the right wall 17, the left wall 16, and the front wall 19). The boundary line region 21 is positioned between the floor surface region 22 and the wall surface region 20.

図１２は床面の１辺が３６００ｍｍの正方形（８畳相当）の部屋を２つ並べた１６畳相当の部屋の短手方向の壁の中央付近に空気調和機１００を設置した部屋空間に対し、３角法にて床面の壁面を展開した図である。 FIG. 12 shows a room space in which an air conditioner 100 is installed near the center of a short-side wall of a room of 16 tatami mat equivalent to two rooms of a square (equivalent to 8 tatami mat) each having a side of the floor of 3600 mm. It is the figure which developed the wall surface of the floor surface by the triangle method.

図１３は図１２の空気調和機１００の据付条件にて熱画像データを取得する際の床面領域２５、壁面領域２３、床１８と壁面（右側の壁１７、左側の壁１６、正面の壁１９）との境界線領域２４の検知エリア領域を示したものである。空気調和機１００の据付け高さを１８００ｍｍとした場合（図７）に取得できる縦８素子＊横９４分解能から得られる７５２画素相当の熱画像における壁面領域２３と、床面領域２５と、床１８と壁面（右側の壁１７、左側の壁１６、正面の壁１９）との境界線領域２４とを示す。 13 shows a floor area 25, a wall area 23, a floor 18 and a wall surface (right wall 17, left wall 16, front wall when acquiring thermal image data under the installation conditions of the air conditioner 100 of FIG. 19) shows the detection area of the boundary line area 24. When the installation height of the air conditioner 100 is 1800 mm (FIG. 7), the wall surface region 23, the floor surface region 25, and the floor 18 in the thermal image corresponding to 752 pixels obtained from the vertical 8 element * horizontal 94 resolution that can be acquired. And a boundary region 24 between the wall surface (the right wall 17, the left wall 16, and the front wall 19).

空気調和機１００から見て手前側の床面領域２５を検知する検知素子は受光素子ａ〜ｅが支配的となる。図１１と比較すると、検知エリア領域の中央部付近の床面領域２５が広くなっている。また、検知エリア領域の両端付近の床面領域２５が狭くなっている。これは、図１２に示す部屋が、空気調和機１００から見て図１０に示す部屋よりも縦長になっているためである。 The light receiving elements a to e are dominant in the detection element that detects the floor surface region 25 on the near side when viewed from the air conditioner 100. Compared to FIG. 11, the floor surface area 25 near the center of the detection area area is wider. Further, the floor area 25 near both ends of the detection area area is narrowed. This is because the room shown in FIG. 12 is longer than the room shown in FIG. 10 when viewed from the air conditioner 100.

また、壁面領域２３を検知する検知素子は受光素子ｃ〜ｈが主となる。図１１と比較すると、検知エリア領域の中央部付近の壁面領域２３が狭くなっている。また、検知エリア領域の両端付近の壁面領域２３が広くなっている。これも、図１２に示す部屋が、空気調和機１００から見て図１０に示す部屋よりも縦長になっているためである。 In addition, the light receiving elements c to h are the main detecting elements for detecting the wall surface region 23. Compared to FIG. 11, the wall surface region 23 near the center of the detection area region is narrower. Further, the wall surface region 23 near both ends of the detection area region is widened. This is also because the room shown in FIG. 12 is longer than the room shown in FIG. 10 when viewed from the air conditioner 100.

そして、受光素子ｃ〜ｆが左右角度と可動式赤外線センサ３の縦方向配光視野角（図７）の関係上、床１８と壁面（右側の壁１７、左側の壁１６、正面の壁１９）との境界線付近の境界線領域２４を検知することとなる。 The light receiving elements c to f have a floor 18 and a wall surface (the right wall 17, the left wall 16, the front wall 19) because of the relationship between the left and right angles and the vertical light distribution viewing angle of the movable infrared sensor 3 (FIG. 7). ) Is detected near the boundary line.

従って、図１３においても、取得される熱画像において床面領域２５は下部領域となり、壁面領域２３は上部領域となり、床１８と壁面（右側の壁１７、左側の壁１６、正面の壁１９）との境界線領域２４が、床面領域２５と壁面領域２３の間の位置付けとなる。 Accordingly, also in FIG. 13, the floor area 25 is a lower area and the wall area 23 is an upper area in the acquired thermal image, and the floor 18 and the wall surface (the right wall 17, the left wall 16, and the front wall 19). The boundary line area 24 is positioned between the floor area 25 and the wall area 23.

図１０は床面の１辺が３６００ｍｍの正方形（８畳相当）の部屋を２つ並べた１６畳相当の部屋の長手方向の壁の右側端付近に空気調和機１００を設置した部屋空間に対し、３角法にて床面と壁面を展開した図である。 FIG. 10 shows a room space in which an air conditioner 100 is installed near the right end of a longitudinal wall of a room of 16 tatami mat equivalent to two square rooms (equivalent to 8 tatami mat) each having a floor of 3600 mm. It is the figure which developed the floor surface and the wall surface by the triangle method.

図１５は図１０の空気調和機１００の据付条件にて熱画像データを取得する際の床面領域２８、壁面領域２６、床面と壁面との境界線領域２７の検知エリア領域を示す図である。空気調和機１００の据付け高さを１８００ｍｍとした場合（図７）に取得できる縦８素子＊横９４分解能から得られる７５２画素相当の熱画像における壁面領域２６と、床面領域２８と、床１８と壁面（右側の壁１７、左側の壁１６、正面の壁１９）との境界線領域２７とを示す。 Figure 15 is a diagram showing a detection area area border region 27 of the floor surface area 28, the wall surface area 26, the floor and the wall in acquiring thermal image data by installation conditions of the air conditioner 100 in FIG. 10 is there. When the installation height of the air conditioner 100 is set to 1800 mm (FIG. 7), the wall surface area 26, the floor area 28, and the floor 18 in the thermal image corresponding to 752 pixels obtained from 8 vertical elements * 94 horizontal resolution that can be acquired. And a boundary region 27 between the wall surface (the right wall 17, the left wall 16, and the front wall 19).

空気調和機１００から見て手前側の床面領域２５を検知する検知素子は受光素子ａ〜ｅが支配的となる。床面領域２８が、検知エリア領域の左側に偏る。これは、部屋の長手方向の壁の右側端付近に空気調和機１００を設置したため、可動式赤外線センサ３が中央付近から右端の間を左右方向に可動する場合、床１８が検知領域に入らないからである。 The light receiving elements a to e are dominant in the detection element that detects the floor surface region 25 on the near side when viewed from the air conditioner 100. The floor area 28 is biased to the left side of the detection area area. This is because the air conditioner 100 is installed near the right end of the wall in the longitudinal direction of the room, so that the floor 18 does not enter the detection region when the movable infrared sensor 3 moves in the left-right direction from near the center to the right end. Because.

また、受光素子ａ〜ｈの全てが、壁面領域２６を検知する。壁面領域２６が、検知エリア領域の左から右に向かって広くなっている。検知エリア領域の右側の約１／３は、壁面領域２６だけになっている。これも、部屋の長手方向の壁の右側端付近に空気調和機１００を設置したためである。 Further, all of the light receiving elements a to h detect the wall surface region 26. The wall surface area 26 is widened from the left to the right of the detection area area. About 1/3 on the right side of the detection area is only the wall surface area 26. This is also because the air conditioner 100 is installed near the right end of the longitudinal wall of the room.

そして、受光素子ａ〜ｆが左右角度と可動式赤外線センサ３の縦方向配光視野角（図７）の関係上、床１８と壁面（右側の壁１７、左側の壁１６、正面の壁１９）との境界線付近の境界線領域２７を検知することとなる。部屋の長手方向の壁の右側端付近に空気調和機１００を設置したため、境界線領域２７も検知エリア領域の右側の約１／３には存在しない。 The light receiving elements a to f have a floor 18 and a wall surface (the right wall 17, the left wall 16, and the front wall 19) because of the relationship between the left and right angles and the vertical light distribution viewing angle of the movable infrared sensor 3 (FIG. 7). ) Is detected in the vicinity of the boundary line 27). Since the air conditioner 100 is installed near the right end of the wall in the longitudinal direction of the room, the boundary line area 27 does not exist in about 1/3 of the right side of the detection area area.

次に、可動式赤外線センサ３を用いて取得することができる部屋の熱画像データの一例を説明する。空気調和機１００の冷房又は暖房運転を行う。このとき、上下フラップ４３は、吹き出し風が水平以上となる向きに固定する。吹出口４２から吹き出す調和空気の温度が、室内空気よりも所定の温度差がある状態を所定時間維持してその間に部屋の熱画像データを可動式赤外線センサ３を用いて取得する。左右フラップ４４は、右側に最大に傾けた第１の状態と、左側に最大に傾けた第２の状態との夫々について、熱画像データを取得するものとする。但し、左右フラップ４４の傾けは、最大でなくてもよい。 Next, an example of room thermal image data that can be acquired using the movable infrared sensor 3 will be described. The air conditioner 100 is cooled or heated. At this time, the upper and lower flaps 43 are fixed in a direction in which the blown air becomes horizontal or higher. The temperature of the conditioned air blown out from the air outlet 42 is maintained for a predetermined time in a state where there is a predetermined temperature difference from the room air, and the thermal image data of the room is acquired using the movable infrared sensor 3 during that time. The left and right flaps 44 acquire thermal image data for each of the first state tilted to the maximum on the right side and the second state tilted to the maximum on the left side. However, the inclination of the left and right flaps 44 may not be the maximum.

図１６は部屋の据付壁５０の中央付近に空気調和機１００を据付け、吹出し風２９を右側に吹出す場合の斜視図（ａ）と吹出し風３０を左側に吹出す場合の斜視図（ｂ）である。吹出し風２９を右側に吹出す場合は、左右フラップ４４を右側に最大に傾ける（第１の状態）。また、吹出し風３０を左側に吹出す場合は、左右フラップ４４を左側に最大に傾ける（第２の状態）。但し、左右フラップ４４の左右への傾きは、最大でなくてもよい。 FIG. 16 is a perspective view when the air conditioner 100 is installed near the center of the installation wall 50 in the room and the blowing air 29 is blown to the right side, and a perspective view when the blowing air 30 is blown to the left side (b). It is. When blowing the blowing air 29 to the right, the left and right flaps 44 are tilted to the right to the maximum (first state). Further, when blowing the blown air 30 to the left, the left and right flaps 44 are tilted to the left to the maximum (second state). However, the inclination of the left and right flaps 44 to the left and right may not be the maximum.

また、図１７は部屋の据付壁５０の右端付近に空気調和機１００を据付け、吹出し風を右側に吹出す場合の斜視図（ａ）と吹出し風を左側に吹出す場合の斜視図（ｂ）である。左右フラップ４４の向きは、図１６の場合と同様である。 FIG. 17 is a perspective view when the air conditioner 100 is installed near the right end of the installation wall 50 in the room, and the blowing air is blown to the right side, and a perspective view when the blowing air is blown to the left side (b). It is. The directions of the left and right flaps 44 are the same as in the case of FIG.

図１６（ａ）に示す据付・運転条件で取得した部屋の熱画像データを図１８に示す。この場合、部屋の据付壁５０の中央付近に空気調和機１００を据付け、室内空気と所定の温度差のある吹出し風２９を右側に吹出すので、熱画像データには右端付近に、右側の壁１７の温度変化が現れる。この右側の壁１７の温度変化を、右壁面温度変化分布３２と定義する。部屋の右側の壁１７以外の部分には、温度変化は現れない。 FIG. 18 shows thermal image data of the room acquired under the installation / operation conditions shown in FIG. In this case, the air conditioner 100 is installed near the center of the installation wall 50 of the room, and the blowing air 29 having a predetermined temperature difference from the room air is blown to the right side. A temperature change of 17 appears. The temperature change of the right wall 17 is defined as a right wall temperature change distribution 32. A temperature change does not appear in any part other than the wall 17 on the right side of the room.

図１６（ｂ）に示す据付・運転条件で取得した部屋の熱画像データを図１９に示す。この場合、部屋の据付壁５０の中央付近に空気調和機１００を据付け、室内空気と所定の温度差のある吹出し風３０を左側に吹出すので、熱画像データには左端付近に、左側の壁１６の温度変化が現れる。この左側の壁１６の温度変化を、左壁面温度変化分布３１と定義する。部屋の左側の壁１６以外の部分には、温度変化は現れない。 FIG. 19 shows the thermal image data of the room acquired under the installation / operation conditions shown in FIG. In this case, the air conditioner 100 is installed near the center of the installation wall 50 in the room, and the blowout air 30 having a predetermined temperature difference from the room air is blown out to the left side. Sixteen temperature changes appear. This temperature change of the left wall 16 is defined as a left wall temperature change distribution 31. A temperature change does not appear in any part other than the left wall 16 of the room.

図２０は図１８と図１９とを合わせた図である。右壁面温度変化分布３２と左壁面温度変化分布３１とが左右対称に現れる。右壁面温度変化分布３２と左壁面温度変化分布３１とは、面積が等しく、且つ熱分布の温度も同等である。 FIG. 20 is a combination of FIG. 18 and FIG. The right wall temperature change distribution 32 and the left wall temperature change distribution 31 appear symmetrically. The right wall surface temperature change distribution 32 and the left wall surface temperature change distribution 31 have the same area and the same heat distribution temperature.

図１７（ａ）に示す据付・運転条件で取得した部屋の熱画像データを図２１に示す。この場合、部屋の据付壁５０の右端付近に空気調和機１００を据付け、室内空気と所定の温度差のある吹出し風２９を右側に吹出すので、熱画像データには右端付近に、右側の壁１７の温度変化が現れる。この右側の壁１７の温度変化を、右壁面温度変化分布３４と定義する。部屋の右側の壁１７以外の部分には、温度変化は現れない。右壁面温度変化分布３４は、図１８の右壁面温度変化分布３２と比較すると、面積が広くなると共に、熱分布の温度も高くなっている。熱分布の温度の違いは、ハッチングの種類を変えて表わしている。 FIG. 21 shows the thermal image data of the room acquired under the installation / operation conditions shown in FIG. In this case, the air conditioner 100 is installed in the vicinity of the right end of the installation wall 50 in the room, and the blowing air 29 having a predetermined temperature difference from the room air is blown out on the right side. A temperature change of 17 appears. The temperature change of the right wall 17 is defined as a right wall temperature change distribution 34. A temperature change does not appear in any part other than the wall 17 on the right side of the room. The right wall surface temperature change distribution 34 has a larger area and a higher heat distribution temperature than the right wall surface temperature change distribution 32 of FIG. The difference in temperature of the heat distribution is expressed by changing the type of hatching.

図１７（ｂ）に示す据付・運転条件で取得した部屋の熱画像データを図２２に示す。この場合、部屋の据付壁５０の右端付近に空気調和機１００を据付け、室内空気と所定の温度差のある吹出し風３０を左側に吹出すので、熱画像データには左端付近に、左側の壁１６の温度変化が現れる。この右側の壁１７の温度変化を、左壁面温度変化分布３３と定義する。部屋の左側の壁１６以外の部分には、温度変化は現れない。左壁面温度変化分布３３は、図１９の左壁面温度変化分布３１と比較すると、面積が狭くなると共に、熱分布の温度も低くなっている。熱分布の温度の違いは、ハッチングの種類を変えて表わしている。左壁面温度変化分布３３のハッチングは、左壁面温度変化分布３１のハッチングよりも粗くすることで、熱分布の温度（温度変化）が低いことを表している。 FIG. 22 shows the thermal image data of the room acquired under the installation / operation conditions shown in FIG. In this case, the air conditioner 100 is installed in the vicinity of the right end of the room installation wall 50, and the blowout air 30 having a predetermined temperature difference from the room air is blown out on the left side. Sixteen temperature changes appear. The temperature change of the right wall 17 is defined as a left wall temperature change distribution 33. A temperature change does not appear in any part other than the left wall 16 of the room. Compared with the left wall surface temperature change distribution 31 of FIG. 19, the left wall surface temperature change distribution 33 has a smaller area and a lower temperature of the heat distribution. The difference in temperature of the heat distribution is expressed by changing the type of hatching. The hatching of the left wall surface temperature change distribution 33 indicates that the temperature (temperature change) of the heat distribution is low by making it rougher than the hatching of the left wall surface temperature change distribution 31.

図２３は図２１と図２２とを合わせた図である。右壁面温度変化分布３４と左壁面温度変化分布３３とを比較すると、右壁面温度変化分布３４の面積が左壁面温度変化分布３３の面積よりも広くなり、且つ右壁面温度変化分布３４の熱分布の温度（温度変化）が左壁面温度変化分布３３の熱分布の温度（温度変化）が高くなっている。熱分布の温度（温度変化）の違いは、ハッチングの種類の違いで表わしている。 FIG. 23 is a combination of FIG. 21 and FIG. When the right wall temperature change distribution 34 and the left wall temperature change distribution 33 are compared, the area of the right wall temperature change distribution 34 is larger than the area of the left wall temperature change distribution 33 and the heat distribution of the right wall temperature change distribution 34 is. The temperature (temperature change) of the heat distribution of the left wall surface temperature change distribution 33 is high (temperature change). The difference in temperature (temperature change) of the heat distribution is represented by the difference in the type of hatching.

図示はしないが、部屋の据付壁５０の左端付近に空気調和機１００を据付ける場合は、図２３と左右を逆にした熱画像データが得られることは明白である。 Although not shown, when the air conditioner 100 is installed near the left end of the installation wall 50 in the room, it is apparent that thermal image data that is the opposite of that in FIG. 23 is obtained.

以上の結果を踏まえて、空気調和機１００の据付時等に、自動的に部屋における空気調和機１００の据付位置を空気調和機１００自身が判断して、それに合わせた吹き出し風向に設定する方法について説明する。従来、据付時等に、据付業者又は使用者がリモコンで空気調和機１００の据付位置の入力を行っていた作業は、上記の自動的な据付位置設定処理により、不要となる。リモコンの据付位置入力部も不要となる。 Based on the above results, when the air conditioner 100 is installed, etc., the air conditioner 100 itself automatically determines the installation position of the air conditioner 100 in the room, and sets the blowing wind direction according to it. explain. Conventionally, the installation work or the user of inputting the installation position of the air conditioner 100 with a remote controller at the time of installation or the like is not required by the above-described automatic installation position setting process. A remote control installation position input unit is also unnecessary.

空気調和機１００の据付位置を空気調和機１００自身が判断してそれに合わせた吹き出し風向に設定する処理を、「据付位置自動判定処理」と定義する。 The process in which the air conditioner 100 itself determines the installation position of the air conditioner 100 and sets the blowing air direction according to the determination is defined as “installation position automatic determination process”.

据付位置自動判定処理を行う時期（タイミング）について、先ず説明する。以下の幾つかが考えられる。
（１）運転起動時に常時行い、ある検知回数を超えたら確定情報として以後は行わない。（２）運転起動時に常時行う。
（３）リモコン又は本体に、据付位置自動判定処理ボタンを設け、この据付位置自動判定処理ボタンが押された場合のみ据付位置自動判定処理が行われる。このケースは、据付時又は移設時に据付業者又は使用者が行う。 The timing (timing) for performing the installation position automatic determination process will be described first. Some of the following are possible.
(1) It is always performed at the time of starting operation, and if it exceeds a certain number of detections, it will not be performed thereafter as confirmed information. (2) Always when starting operation.
(3) The installation position automatic determination processing button is provided on the remote controller or the main body, and the installation position automatic determination processing is performed only when this installation position automatic determination processing button is pressed. This case is performed by the installer or user during installation or relocation.

上記（１）〜（３）の中では、（１）が有力である。但し、（１）では空気調和機１００を移設する場合（稀ではあるが）、空気調和機１００の部屋での据付位置が変わる場合もあることから、移設に伴い据付位置自動判定処理をやり直すプログラムを追加する必要がある。そのプログラムとしては、初回（移設前）の据付位置自動判定処理における部屋の熱画像データをメモリに記憶しておき、メモリに記憶された部屋の熱画像データを定期的に更新する処理を追加する。そして、メモリに記憶された部屋の熱画像データが変化したら、移設と判断して、据付位置自動判定処理をやり直す等の方法が考えられる。 Among the above (1) to (3), (1) is dominant. However, in (1), when the air conditioner 100 is moved (although rarely), the installation position in the room of the air conditioner 100 may change. Need to be added. As the program, the thermal image data of the room in the first automatic installation position determination process (before the relocation) is stored in the memory, and the process of periodically updating the thermal image data of the room stored in the memory is added. . If the thermal image data of the room stored in the memory changes, it can be determined that the room is to be moved and the installation position automatic determination process is performed again.

据付位置自動判定処理の指令が出された場合、空気調和機１００の制御部は、以下の処理を行う。
（１）冷房又は暖房運転を開始する。
（２）上下フラップ４３は水平吹きとする。
（３）左右フラップ４４を右側に最大又はそれに近い角度で傾け、可動式赤外線センサ３を走査させて、第１の部屋の熱画像データを取得する（例えば、図１８、図２１）。
（４）左右フラップ４４を左側に最大又はそれに近い角度で傾け、可動式赤外線センサ３を走査させて、第２の部屋の熱画像データを取得する（例えば、図１９、図２２）。
（５）第１の部屋の熱画像データと、第２の部屋の熱画像データとを比較する（例えば、図２０、図２３）。そして、その比較結果に基づいて、部屋における空気調和機１００の据付位置を判定する。 When a command for installation position automatic determination processing is issued, the control unit of the air conditioner 100 performs the following processing.
(1) Start cooling or heating operation.
(2) The upper and lower flaps 43 are horizontally blown.
(3) The left and right flaps 44 are tilted to the right at a maximum or near angle, and the movable infrared sensor 3 is scanned to acquire thermal image data of the first room (for example, FIGS. 18 and 21).
(4) The left and right flaps 44 are tilted to the left at a maximum or near angle, and the movable infrared sensor 3 is scanned to acquire thermal image data of the second room (for example, FIGS. 19 and 22).
(5) The thermal image data of the first room is compared with the thermal image data of the second room (for example, FIGS. 20 and 23). And the installation position of the air conditioner 100 in a room is determined based on the comparison result.

判定方法としては、以下に示す方法が考えられる。
（１）吹き出し温度の影響による熱分布の面積を左右にて比較し、同じ面積の場合は中央据付けであると判断する。例えば、図２０の右壁面温度変化分布３２と左壁面温度変化分布３１は、面積が等しいので、中央据付けであると判断する。また、図２３の右壁面温度変化分布３４と左壁面温度変化分布３３は、右壁面温度変化分布３４の面積が左壁面温度変化分布３３の面積よりも広くなっているので、コーナー据付（据付壁５０の右端付近に据付）と判断する。
（２）吹き出し温度の影響による熱分布の温度（温度変化）を左右で比較することで、空気調和機１００の部屋での据付位置を判断する。例えば、図２０の右壁面温度変化分布３２と左壁面温度変化分布３１は、熱分布の温度（温度変化）が等しいので、中央据付けであると判断する。また、図２３の右壁面温度変化分布３４と左壁面温度変化分布３３は、右壁面温度変化分布３４の熱分布の温度（温度変化）が左壁面温度変化分布３３の熱分布の温度（温度変化）よりも高いので、コーナー据付（据付壁５０の右端付近に据付）と判断する。
（３）吹き出し温度の影響による熱分布の温度（温度変化）と面積との積を左右で比較することで、空気調和機１００の部屋での据付位置を判断する。
上記（１）〜（３）のいずれか、若しくは（１）＋（２）の条件で、空気調和機１００の部屋での据付位置を判断する。 As a determination method, the following method can be considered.
(1) The areas of the heat distribution due to the influence of the blowing temperature are compared on the left and right, and if they are the same area, it is determined that the installation is central. For example, the right wall surface temperature change distribution 32 and the left wall surface temperature change distribution 31 of FIG. 20 have the same area, and therefore are determined to be centrally installed. Further, the right wall surface temperature change distribution 34 and the left wall surface temperature change distribution 33 in FIG. 23 have a larger area than the left wall surface temperature change distribution 33 because the area of the right wall surface temperature change distribution 34 is larger than the area of the left wall surface temperature change distribution 33. It is determined that it is installed near the right end of 50).
(2) The installation position in the room of the air conditioner 100 is determined by comparing the temperature (temperature change) of the heat distribution due to the influence of the blowing temperature on the left and right. For example, the right wall surface temperature change distribution 32 and the left wall surface temperature change distribution 31 in FIG. 20 have the same heat distribution temperature (temperature change), and thus are determined to be centrally installed. Further, the right wall temperature change distribution 34 and the left wall temperature change distribution 33 in FIG. 23 indicate that the heat distribution temperature (temperature change) of the right wall temperature change distribution 34 is the temperature of the left wall temperature change distribution 33 (temperature change). Therefore, it is determined that the corner is installed (installed near the right end of the installation wall 50).
(3) The installation position of the air conditioner 100 in the room is determined by comparing the product of the temperature (temperature change) of heat distribution due to the influence of the blowing temperature and the area on the left and right.
The installation position of the air conditioner 100 in the room is determined based on any one of the above (1) to (3) or (1) + (2).

空気調和機１００の部屋での据付位置が略据付壁５０の右端付近に据付と判断された場合は、左右フラップ４４の向きを、据付壁５０に対して、中央を中心に左右に所定角度スイングするように制御する。 When it is determined that the installation position of the air conditioner 100 in the room is substantially installed near the right end of the installation wall 50, the direction of the left and right flaps 44 is swung to the right and left about the center with respect to the installation wall 50 by a predetermined angle. Control to do.

空気調和機１００の部屋での据付位置が略据付壁５０の右端付近と判断された場合は、左右フラップ４４の向きを、据付壁５０の中央から右方向に所定角度スイングするように制御する。 When it is determined that the installation position of the air conditioner 100 in the room is substantially near the right end of the installation wall 50, the direction of the left and right flaps 44 is controlled to swing from the center of the installation wall 50 to the right by a predetermined angle.

空気調和機１００の部屋での据付位置が略据付壁５０の左端付近と判断された場合は、左右フラップ４４の向きを、据付壁５０の中央から左方向に所定角度スイングするように制御する。 When it is determined that the installation position of the air conditioner 100 in the room is substantially near the left end of the installation wall 50, the direction of the left and right flaps 44 is controlled to swing from the center of the installation wall 50 to the left by a predetermined angle.

図２４は空気調和機１００と左右壁との距離Ｌと面積（画素数）Ｓとの関係を示す図である。図２４の縦軸の面積（画素数）Ｓは、吹き出し温冷風による壁面温度の影響を面積に置き換えたものである。 FIG. 24 is a diagram showing the relationship between the distance L and the area (number of pixels) S between the air conditioner 100 and the left and right walls. The area (number of pixels) S on the vertical axis in FIG. 24 is obtained by replacing the influence of the wall surface temperature by the blown hot / cold air with the area.

取得される熱画像の壁面温度の影響度から空気調和機１００と左右壁との距離Ｌを求め、左右の壁面温度の面積を比較することで据付位置関係を判断することができる。 The installation positional relationship can be determined by obtaining the distance L between the air conditioner 100 and the left and right walls from the degree of influence of the wall temperature of the acquired thermal image and comparing the areas of the left and right wall temperatures.

空気調和機１００と左右壁との距離Ｌに応じて、左右フラップ４４のスイング角度を変えるようにしてもよい。空気調和機１００と左右壁との距離Ｌが長くなれば、中央よりスイングする側の反対側にスイング角度を広げることができる。 The swing angle of the left and right flaps 44 may be changed according to the distance L between the air conditioner 100 and the left and right walls. If the distance L between the air conditioner 100 and the left and right walls becomes longer, the swing angle can be widened to the opposite side of the swing side from the center.

以上のように、この実施の形態によれば、空気調和機１００自身が、部屋での据付位置（主に据付壁５０での左右方向の位置）を判断して、その据付位置に応じた吹き出し風の制御を行うので、従来、据付時等に、据付業者又は使用者がリモコンで空気調和機１００の据付位置の入力を行っていた作業は、不要となる。また、リモコンの据付位置入力部も不要となる。さらに、制御部（マイクロコンピュータ）の制御プログラムの変更のみで対応できる。 As described above, according to this embodiment, the air conditioner 100 itself determines the installation position in the room (mainly the position in the left-right direction on the installation wall 50), and the blowout according to the installation position. Since the wind is controlled, conventionally, an installation contractor or a user does not need to input an installation position of the air conditioner 100 with a remote controller at the time of installation or the like. Moreover, the installation position input part of the remote control is not required. Furthermore, it can respond only by changing the control program of the control unit (microcomputer).

なお、上記の説明においては、可動式赤外線センサ３を左右方向に所定角度範囲で回転駆動させて空気調和機１００を設置した部屋空間の熱画像データを取得したが、熱画像データを取得する赤外線センサは可動式赤外線センサ３に限定されるものではない。配光視野角が、対象とする部屋空間全体をほぼカバーするような固定式の１つの赤外線センサを用いて空気調和機１００を設置した部屋空間の熱画像データを取得してもよいし、または、視野がそれぞれ異なる固定式の赤外線センサを複数用いて、それぞれが同タイミングで取得した熱画像データをつなげて空気調和機１００を設置した部屋空間の熱画像データを取得してもよい。 In the above description, thermal image data of the room space where the air conditioner 100 is installed is obtained by rotating the movable infrared sensor 3 in the left-right direction within a predetermined angle range. The sensor is not limited to the movable infrared sensor 3. Thermal image data of the room space in which the air conditioner 100 is installed may be acquired using one fixed infrared sensor whose light distribution viewing angle almost covers the entire target room space, or Alternatively, a plurality of fixed infrared sensors having different fields of view may be used, and thermal image data of the room space in which the air conditioner 100 is installed may be acquired by connecting the thermal image data acquired at the same timing.
