Description

空気調和機Air conditioner
　本発明は、室内機に撮像装置を設置した空気調和機に関するものである。 The present invention relates to an air conditioner in which an imaging device is installed in an indoor unit.
　従来の空気調和機には、運転開始後早急に室内が設定温度に達するよう風を吹出すものが多い。このような空気調和機では、冷房時や、室内気温が低い場合に急激に暖房運転を行った場合に、風の吹出し口に結露が生じる場合があった。この結露対策のため、直接吹出し口に風が当たらないように開口部を大きくとることが提案されている（例えば、特許文献１参照）。 Many conventional air conditioners blow out the wind so that the room reaches the set temperature as soon as the operation starts. In such an air conditioner, condensation may occur at the air outlet when cooling or when the heating operation is suddenly performed when the room temperature is low. In order to prevent this dew condensation, it has been proposed to make the opening large so that the wind does not directly hit the outlet (for example, see Patent Document 1).
　また、一般的な撮像装置の結露対策としては、撮像装置周辺に発熱体（例えば周辺回路）を設置し、撮像装置のカバーガラス内外の温度差を低減させているものがある（例えば、特許文献２参照）。 In addition, as a countermeasure against dew condensation in a general imaging apparatus, there is a technique in which a heating element (for example, a peripheral circuit) is installed around the imaging apparatus to reduce a temperature difference between the inside and outside of the cover glass of the imaging apparatus (for example, Patent Documents). 2).

　しかしながら、特許文献１に記載の手法では、空気調和機に撮像装置を設置した場合には、風が当たらないように設置位置を制限しなければならないという課題がある。また、特許文献２のように、発熱体で撮像装置周辺を加熱するには、そのための電力が必要となるという問題点がある。 However, the technique described in Patent Document 1 has a problem that when the imaging device is installed in the air conditioner, the installation position must be limited so that the wind does not hit. In addition, as in Patent Document 2, in order to heat the periphery of the imaging device with a heating element, there is a problem that electric power is required.
　本発明は、従来技術の有するこのような問題点に鑑みてなされたものであり、撮像装置の設置位置を制限することなく、かつ省電力で結露対策が可能な空気調和機を提供することを目的としている。 The present invention has been made in view of such problems of the prior art, and it is an object of the present invention to provide an air conditioner capable of preventing condensation without limiting the installation position of the imaging device and saving power. It is aimed.
　上記目的を達成するため、本発明は、撮像装置が設置された室内機を備える空気調和機であって、風向を制御するルーバーと、室内機の運転開始後、空調空間の温度が所定温度になるまでの間、ルーバーの向きを撮像装置に風が当たらない向きに向ける制御部とを備える。 In order to achieve the above object, the present invention is an air conditioner including an indoor unit in which an imaging device is installed, and a louver that controls a wind direction, and the temperature of an air-conditioned space is set to a predetermined temperature after the operation of the indoor unit is started. Until it becomes, the control part which orient | assigns the direction of a louver to the direction which a wind does not hit an imaging device is provided.
　本発明の空気調和機は、撮像装置の結露対策として、運転開始後一定時間の間、撮像装置に風を当てないように風向がコントロールされるので、撮像装置の設置場所を制限する事無く、省電力で結露対策が可能な空気調和機を提供することが可能となる。 In the air conditioner of the present invention, as a countermeasure against dew condensation of the image pickup device, the wind direction is controlled so as not to blow the image pickup device for a certain period of time after the start of operation, so without limiting the installation location of the image pickup device, It is possible to provide an air conditioner that can conserve condensation while saving power.

　本発明は、撮像装置が設置された室内機を備える空気調和機であって、風向を制御するルーバーと、前記室内機の運転開始後、空調空間の温度が所定温度になるまでの間、前記ルーバーの向きを前記撮像装置に風が当たらない向きに向ける制御部とを備える。この構成により、撮像装置の設置場所を制限する事無く、省電力で結露対策が可能な空気調和機を提供することが可能となる。 The present invention is an air conditioner including an indoor unit in which an imaging device is installed, and the louver that controls the wind direction, and after the start of the operation of the indoor unit until the temperature of the air-conditioned space reaches a predetermined temperature, A control unit that directs the direction of the louvers so that the wind does not hit the imaging apparatus. With this configuration, it is possible to provide an air conditioner capable of taking measures against condensation with power saving without limiting the installation location of the imaging device.
　また、前記空気調和機は、空調空間の温度を検出する温度センサをさらに備え、前記制御部は、前記温度センサが検出した温度が設定された温度になるまでの間、前記ルーバーの向きを前記撮像装置に風が当たらない向きに向ける。このように、結露が発生すると想定される時間だけルーバーの向きを撮像装置に向けないようにしているため、最適な時間でルーバーの向きを設定された向きに変えることが可能となる。 The air conditioner further includes a temperature sensor that detects a temperature of the air-conditioned space, and the control unit changes the direction of the louver until the temperature detected by the temperature sensor reaches a set temperature. Aim the camera in a direction that is not exposed to wind. As described above, since the direction of the louver is not directed toward the imaging apparatus for the time when condensation is expected to occur, the direction of the louver can be changed to the set direction in an optimum time.
　なお、前記制御部は、前記温度センサが検出した温度と前記室内機の吹き出し温度との差が所定の温度差以下になるまでの間、前記制御を行うようにしても良い。これによっても同様に、撮像装置の結露を防止することができる。 The control unit may perform the control until the difference between the temperature detected by the temperature sensor and the blowout temperature of the indoor unit becomes equal to or less than a predetermined temperature difference. This also prevents condensation of the imaging device.
　また、前記ルーバーが複数の羽板からなる場合、前記制御部は、前記撮像装置に近い羽板の向きを前記撮像装置に風が当たらない向きに向ける。このように、撮像装置に近い羽板のみを撮像装置に風が当たらない向きに向けることで、他の羽板を異なる方向に向けることが可能となるため、運転開始後から利用者に好適な空調を行いつつ、結露を防止することが可能となる。 Also, when the louver is composed of a plurality of slats, the control unit directs the direction of the slats close to the imaging device so that the wind does not hit the imaging device. In this way, by directing only the slats close to the imaging device in a direction where the wind does not hit the imaging device, other slats can be directed in different directions, which is suitable for the user after the start of driving. It is possible to prevent condensation while performing air conditioning.
　（実施の形態１）
　以下、本発明の実施の形態について、図面を参照しながら説明する。 (Embodiment 1)
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
　図１は、本発明の第１の実施の形態における空気調和機が備える室内機の構成を示す図で、図２は図１の室内機の断面図である。図１及び図２において、室内機１は、前面パネル２と、撮像装置６と、ルーバー１１と、ルーバー駆動用モータ５と、制御部７と、温度センサ１０とを備えている。図２では、前面パネル２は開いた状態である。 FIG. 1 is a diagram showing a configuration of an indoor unit included in an air conditioner according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view of the indoor unit of FIG. 1 and 2, the indoor unit 1 includes a front panel 2, an imaging device 6, a louver 11, a louver driving motor 5, a control unit 7, and a temperature sensor 10. In FIG. 2, the front panel 2 is in an open state.
　前面パネル２は、室内機１の前面に、開閉可能に取り付けられる。撮像装置６は、室内機本体に取り付けられる。本実施の形態１では、例示的に、撮像装置６は室内機本体の下部中央に取り付けられる。このような撮像装置６は、空調空間（例えば室内）の状況を撮影する。なお、本願には本質的に無関係なため説明を殆ど行わないが、撮像装置６により撮影された画像は、例えば風向きを制御するために用いられる。 The front panel 2 is attached to the front surface of the indoor unit 1 so that it can be opened and closed. The imaging device 6 is attached to the indoor unit main body. In the first embodiment, for example, the imaging device 6 is attached to the lower center of the indoor unit main body. Such an imaging device 6 images the condition of an air-conditioned space (for example, indoors). In addition, since it is irrelevant to the present application and will not be described, the image taken by the imaging device 6 is used, for example, to control the wind direction.
　また、ルーバー１１は、前面パネル２の背後に設置されており、ルーバー駆動用モータ５により与えられる駆動力により向きを変える。制御部７は、このルーバー駆動用モータ５に制御信号（つまり指示）を出す。この制御信号に基づきルーバー１１の向きを変えることにより、室内機１からの風の向きが調整される。 The louver 11 is installed behind the front panel 2 and changes its direction by the driving force applied by the louver driving motor 5. The control unit 7 issues a control signal (that is, an instruction) to the louver driving motor 5. The direction of the wind from the indoor unit 1 is adjusted by changing the direction of the louver 11 based on this control signal.
　また、室内機１には、空調空間の温度を検出するための温度センサ１０が設けられる。 Moreover, the indoor unit 1 is provided with a temperature sensor 10 for detecting the temperature of the air-conditioned space.
　ここでまず、結露の現象例を図３～図５を用いて説明する。図３は、撮像装置６の模式図で、支持台２４の上に画像センサ２１が設置され、画像センサ２１を覆うように鏡筒２２が設置されて、鏡筒２２の先端にレンズ２３が設置される。通常、撮像装置６の鏡筒２２の内側の空間には湿気がない状態であるが、長期間の使用によっては鏡筒２２の内側の空間が湿気を有することがあり、このような場合には、レンズ２３に結露が生じる可能性がある。 Here, first, an example of the phenomenon of condensation will be described with reference to FIGS. FIG. 3 is a schematic diagram of the imaging device 6. The image sensor 21 is installed on the support base 24, the lens barrel 22 is installed so as to cover the image sensor 21, and the lens 23 is installed at the tip of the lens barrel 22. Is done. Normally, the space inside the lens barrel 22 of the image pickup device 6 is in a state where there is no moisture, but the space inside the lens barrel 22 may have moisture depending on long-term use. Condensation may occur on the lens 23.
　図４は空気調和機を暖房運転した場合の結露現象の様子を示したものであり、図５は空気調和機を冷房運転した場合の結露現象を示したものである。 FIG. 4 shows the state of the dew condensation phenomenon when the air conditioner is operated for heating, and FIG. 5 shows the dew condensation phenomenon when the air conditioner is operated for cooling.
　空気調和機で暖房を開始する場合、運転開始前は室内気温が低く、撮像装置６も室内気温と同じく低温である。その低温である撮像装置６に空気調和機からの暖かい風２５があたると、撮像装置６の外側は温かくなるが、鏡筒２２とレンズ２３に囲まれた撮像装置６の内側はすぐには熱が伝わらず低温のままである。このように撮像装置６の外側と内側の温度差があるため撮像装置６の外側の温度の高い空気が、撮像装置６の内側の低温に触れることで、図４に示すように撮像装置外側に結露２６を生じる。レンズ２３の上に生じた結露２６はレンズ２３を通過する光を散乱させ、画像センサ２１には散乱光しか届かず、撮像装置６は正しく撮像することができなくなる。 When heating is started with an air conditioner, the room temperature is low before the start of operation, and the imaging device 6 is also at a low temperature, similar to the room temperature. When warm air 25 from the air conditioner hits the low-temperature imaging device 6, the outside of the imaging device 6 becomes warm, but the inside of the imaging device 6 surrounded by the lens barrel 22 and the lens 23 is immediately heated. The temperature remains low. As described above, since there is a temperature difference between the outside and the inside of the imaging device 6, high-temperature air outside the imaging device 6 touches the low temperature inside the imaging device 6, so that the outside of the imaging device 6 becomes outside as shown in FIG. Condensation 26 is produced. Condensation 26 generated on the lens 23 scatters the light passing through the lens 23, and only the scattered light reaches the image sensor 21, and the imaging device 6 cannot capture images correctly.
　また、空気調和機で冷房を開始する場合は、運転開始前は室内気温が高く、撮像装置６も高温である。従って、暖房時と逆に、高温である撮像装置６に空気調和機から冷たい風２５があたることになり、風２５より高温である撮像装置６の内側と外側の温度差で、図５に示すとおり高温側である撮像装置６の内側に結露２６が生じる。レンズ２３の内側に生じた結露２６はレンズ２３を通過する光を散乱させ、画像センサ２１には散乱光しか届かず、撮像装置６は正しく撮像することができなくなる。 In addition, when the air conditioner starts cooling, the room temperature is high before the operation is started, and the imaging device 6 is also hot. Therefore, contrary to heating, the imaging device 6 having a high temperature is hit by a cold wind 25 from the air conditioner, and the temperature difference between the inside and the outside of the imaging device 6 having a temperature higher than the wind 25 is shown in FIG. As described above, condensation 26 is generated inside the imaging device 6 on the high temperature side. Condensation 26 generated inside the lens 23 scatters light passing through the lens 23, and only scattered light reaches the image sensor 21, and the imaging device 6 cannot capture images correctly.
　次に、空気調和機の動作について説明する。 Next, the operation of the air conditioner will be described.
　運転開始後、制御部７は、ルーバー用モータ５に制御信号を与えて、ルーバー１１の向きを、撮像装置６を避ける向きに変更する。これによって、ルーバー１１からの風が撮像装置６に当たらないようにする。図１の例では、撮像装置６が室内機本体の下部中央に設置されている。この撮像装置６を避けるように、制御部７は、室内機１から見て左右方向に風が吹き出されるようルーバー１１の向きを変更する。運転開始から一定時間（例えば７分程度）経過後、制御部７は、改めて制御信号をルーバー用モータ５に与えて、ルーバー１１の向きを、例えばリモートコントローラ（図示せず）を用いて使用者が設定した向きに変更する。このように、運転開始後一定時間の間、撮像装置３に風を当てないことで、例えば、暖房運転時であれば、冷えていた撮像装置６に急激に温風を当てた結果起こる結露を防ぎ、撮像装置６が結露しない温度まで十分に温まった後、リモートコントローラで設定された風向に調整する。 After the start of operation, the control unit 7 gives a control signal to the louver motor 5 to change the direction of the louver 11 so as to avoid the imaging device 6. This prevents the wind from the louver 11 from hitting the imaging device 6. In the example of FIG. 1, the imaging device 6 is installed in the lower center of the indoor unit body. The controller 7 changes the direction of the louver 11 so that the wind blows in the left-right direction when viewed from the indoor unit 1 so as to avoid the imaging device 6. After a certain time (for example, about 7 minutes) has elapsed since the start of operation, the control unit 7 again gives a control signal to the louver motor 5 to change the direction of the louver 11 using, for example, a remote controller (not shown). Change to the direction set by. In this way, by not applying air to the imaging device 3 for a certain period of time after the start of operation, for example, during heating operation, condensation that occurs as a result of suddenly applying hot air to the imaging device 6 that has been cooled is prevented. After the image pickup device 6 is sufficiently warmed to a temperature at which condensation does not occur, the wind direction set by the remote controller is adjusted.
　以上のように、本実施の形態においては、撮像装置６の結露対策として、運転開始後一定時間の間、撮像装置６に風を当てないように風向をコントロールしているので、撮像装置６の設置位置の制限を無くすことが可能となる。また、結露対策のために発熱体を準備する必要もないので、省電力化することもできる。 As described above, in the present embodiment, as a countermeasure against dew condensation of the imaging device 6, the wind direction is controlled so as not to blow the imaging device 6 for a certain period of time after the start of operation. It is possible to eliminate the restriction of the installation position. In addition, since it is not necessary to prepare a heating element as a countermeasure against condensation, it is possible to save power.
　（実施の形態２）
　図６、図７は、本発明の実施の形態２における空気調和機の室内機を示す図である。図６、図７は、図１と比較すると、ルーバー１１が左右ルーバー３と上下ルーバー４とから構成されることが示されている点で相違する。それ以外に相違点は無い。それ故、図６、図７において、図１の構成に相当するものには同一の参照符号を付け、それぞれの説明を省略する。 (Embodiment 2)
6 and 7 are diagrams showing an indoor unit of an air conditioner according to Embodiment 2 of the present invention. FIG. 6 and FIG. 7 differ from FIG. 1 in that the louver 11 is composed of left and right louvers 3 and upper and lower louvers 4. There are no other differences. Therefore, in FIG. 6, FIG. 7, the thing equivalent to the structure of FIG. 1 is attached | subjected with the same referential mark, and each description is abbreviate | omitted.
　図６、図７において、左右ルーバー３は、室内機１から吹き出される風について、左右方向の向きを制御する。上下ルーバー４は、室内機１から吹出される風について、上下方向の向きを制御する。なお、図６、図７には、例示的に、左右ルーバー３の制御により、室内機１から吹出される風の向きとして、左風向８、右風向９が示されている。 6 and 7, the left and right louvers 3 control the direction of the left and right directions of the wind blown from the indoor unit 1. The vertical louver 4 controls the vertical direction of the wind blown from the indoor unit 1. 6 and 7 exemplarily show the left wind direction 8 and the right wind direction 9 as the directions of the wind blown out from the indoor unit 1 by the control of the left and right louvers 3.
　また、図８は、本実施の形態に係る室内機の処理手順を示すフローチャートである。 FIG. 8 is a flowchart showing a processing procedure of the indoor unit according to the present embodiment.
　以下、以上の図面を参照して、本実施の形態に係る空気調和機の室内機１の動作、作用を説明する。 Hereinafter, the operation and action of the indoor unit 1 of the air conditioner according to the present embodiment will be described with reference to the above drawings.
　図８において、室内機１の運転開始後、温度センサ１０は室温を検出し（ステップＳ１０１）、制御部７は、ルーバー用モータ５に制御信号を与えて、左右ルーバー３の風が撮像装置６に当たらない向きになるよう左右ルーバー３の向きを制御する（ステップＳ１０２）。 In FIG. 8, after the operation of the indoor unit 1 is started, the temperature sensor 10 detects the room temperature (step S <b> 101), and the control unit 7 gives a control signal to the louver motor 5, and the wind of the left and right louvers 3 causes the imaging device 6. The direction of the left and right louvers 3 is controlled so as to be in the direction not hitting (step S102).
　次に、温度センサ１０は室温を再度検出し（ステップＳ１０３）、制御部７は、現在の室温がリモートコントローラにより設定された温度と一致したかを判断する（ステップＳ１０４）。不一致の場合、上述のステップＳ１０３→ステップＳ１０４を繰り返す。室温と設定温度が一致した場合（ステップＳ１０４）、制御部７は、ルーバー用モータ５に制御信号を与えて、左右ルーバー３の向きを、リモートコントローラで設定された向きに変更させる（ステップＳ１０５）。この向き変更後の風向はリモートコントローラで設定された風向であるため、図７に示す左風向８と右風向９のように同じ方向を向く場合がある。この場合、撮像装置６に室内機１からの吹き出し風が当たる場合があるが、本実施の形態では、室温が設定温度と一致する迄は撮像装置６に風が当たらないように風向制御し、その後、設定された風向に変更しているため、撮像装置６の結露を防止することができる。また、実施の形態１と同様に、撮像装置６の設置位置の制限を無くすとともに、省電力化も可能となる。 Next, the temperature sensor 10 detects the room temperature again (step S103), and the control unit 7 determines whether the current room temperature matches the temperature set by the remote controller (step S104). If they do not match, the above step S103 → step S104 is repeated. When the room temperature matches the set temperature (step S104), the control unit 7 gives a control signal to the louver motor 5 to change the direction of the left and right louvers 3 to the direction set by the remote controller (step S105). . Since the wind direction after this direction change is the wind direction set by the remote controller, it may be directed in the same direction as the left wind direction 8 and the right wind direction 9 shown in FIG. In this case, there is a case where the blowout wind from the indoor unit 1 hits the imaging device 6, but in this embodiment, the wind direction is controlled so that the imaging device 6 does not hit the wind until the room temperature matches the set temperature. Then, since it has changed to the set wind direction, the condensation of the imaging device 6 can be prevented. Further, similarly to the first embodiment, it is possible to eliminate the restriction of the installation position of the imaging device 6 and to save power.
　（実施の形態３）
　図６、図７及び図９を参照して、本実施の形態における空気調和機の室内機１の動作、作用を説明する。図６、図７は実施の形態２と同じであるので、説明を省略する。 (Embodiment 3)
With reference to FIG.6, FIG7 and FIG.9, operation | movement and an effect | action of the indoor unit 1 of the air conditioner in this Embodiment are demonstrated. 6 and 7 are the same as those in the second embodiment, and a description thereof will be omitted.
　図９は発明の実施の形態３における空気調和機の処理手順を示すフローチャートである。 FIG. 9 is a flowchart showing a processing procedure of the air conditioner according to the third embodiment of the invention.
　図９において、室内機１の運転開始後、温度センサ１０は室温を検出し（ステップＳ２０１）、制御部７は、ルーバー用モータ５に制御信号を与えて、左右ルーバー３の風が撮像装置６に当たらない向きになるよう左右ルーバー３の向きを制御する（ステップＳ２０２）。 In FIG. 9, after the operation of the indoor unit 1 is started, the temperature sensor 10 detects the room temperature (step S <b> 201), and the control unit 7 gives a control signal to the louver motor 5, so that the wind of the left and right louvers 3 is imaged 6. The direction of the left and right louvers 3 is controlled so as to be in a direction not hitting (step S202).
　次に、温度センサ１０は室温を再度検出し（ステップＳ２０３）、制御部７は、現在の室温とリモートコントローラにより設定された温度との差が所定範囲内になったかを判断する（ステップＳ２０４）。所定範囲外の場合、上述のステップＳ２０３→ステップＳ２０４を繰り返す。室温と設定温度との差が所定範囲内に入った場合（ステップＳ２０４）、制御部７は、ルーバー用モータ５に制御信号を与えて、左右ルーバー３の向きを、リモートコントローラで設定された向きに変更させる（ステップＳ２０５）。このように、実施例２と同様、この向き変更後の風向はリモートコントローラで設定された風向であるため、図７に示す左風向８と右風向９のように同じ方向を向く場合がある。この場合、撮像装置６に室内機１からの吹き出し風が当たる場合があるが、本実施の形態では、室温と設定温度との差が所定範囲内になるまで撮像装置６に風が当たらないように風向制御し、その後、設定された風向に変更しているため、撮像装置６の結露を防止することができる。また、実施の形態１と同様に、撮像装置６の設置位置の制限を無くすとともに、省電力化も可能となる。また、結露が発生しないと想定される温度差になるまで左右ルーバー３の向きを撮像装置６に向けないようにしているため、最適な時間で左右ルーバー３の向きを設定された向きに変えることが可能となる。
　（実施の形態４）
　図１０は、本発明の実施の形態４における空気調和機の室内機を示す図である。図１０は、図６、図７と比較すると、左右ルーバー３を構成する各羽板の向きを個別的に制御可能である点で相違する。それ以外に相違点は無いので、図１０において、図６、図７の構成に相当するものには同一の参照符号を付け、それぞれの説明を省略する。図１０において、制御部７は、例えば図８のステップＳ１０２において、ルーバー用モータ５に制御信号を与えて、左右ルーバー３の羽板のうち撮像装置６に近くにあるもののみが撮像装置６に風が当たらない向きになるよう制御する。そして、例えば、室温が設定温度と一致するまでの間、左右ルーバー３の各羽板の向きをこの状態を維持しても構わないし、撮像装置６の近くの羽板に限り、常にこの状態を維持するようにしても構わない。 Next, the temperature sensor 10 detects the room temperature again (step S203), and the control unit 7 determines whether the difference between the current room temperature and the temperature set by the remote controller is within a predetermined range (step S204). . If it is outside the predetermined range, the above-described step S203 → step S204 is repeated. When the difference between the room temperature and the set temperature falls within a predetermined range (step S204), the control unit 7 gives a control signal to the louver motor 5 to change the direction of the left and right louvers 3 to the direction set by the remote controller. (Step S205). As described above, the wind direction after the direction change is the wind direction set by the remote controller in the same manner as in the second embodiment, and thus may be directed in the same direction as the left wind direction 8 and the right wind direction 9 shown in FIG. In this case, there may be a case where the blowing air from the indoor unit 1 hits the imaging device 6, but in this embodiment, the imaging device 6 does not hit the wind until the difference between the room temperature and the set temperature falls within a predetermined range. Since the wind direction is controlled and then changed to the set wind direction, condensation of the imaging device 6 can be prevented. Further, similarly to the first embodiment, it is possible to eliminate the restriction of the installation position of the imaging device 6 and to save power. In addition, since the direction of the left and right louvers 3 is not directed toward the image pickup device 6 until the temperature difference is assumed to cause no condensation, the direction of the left and right louvers 3 is changed to the set direction at an optimum time. Is possible.
(Embodiment 4)
FIG. 10 is a diagram showing an indoor unit of an air conditioner according to Embodiment 4 of the present invention. FIG. 10 differs from FIG. 6 and FIG. 7 in that the direction of each slat constituting the left and right louvers 3 can be individually controlled. Since there is no difference other than that, in FIG. 10, the thing equivalent to the structure of FIG. 6, FIG. 7 is attached with the same referential mark, and each description is abbreviate | omitted. In FIG. 10, for example, in step S <b> 102 of FIG. 8, the control unit 7 gives a control signal to the louver motor 5, and only the blades of the left and right louvers 3 that are close to the imaging device 6 are sent to the imaging device 6. Control the wind so that it does not strike. Then, for example, until the room temperature matches the set temperature, the orientation of each slat of the left and right louvers 3 may be maintained in this state, and this state is always limited only to the slats near the imaging device 6. You may make it maintain.
　このようにすることによっても、実施の形態２と同様、結露を防止することができるとともに、撮像装置６の設置位置の制限を無くすとともに、省電力化も可能となる。さらに、撮像装置６に近い羽板のみを撮像装置６に風が当たらない向きに向けることで、他の羽板を異なる方向に向けることが可能となるため、運転開始後から利用者に好適な空調を行いつつ、結露を防止することが可能となる。 Also in this way, as with the second embodiment, condensation can be prevented, the restriction of the installation position of the imaging device 6 can be eliminated, and power saving can be achieved. Further, by directing only the wing plate close to the imaging device 6 in a direction in which the wind does not hit the imaging device 6, it becomes possible to direct other wing plates in different directions, which is suitable for the user after the start of driving. It is possible to prevent condensation while performing air conditioning.
　なお、上記各実施の形態では、室温が設定温度と一致するまでの間、風向を制御するとしたが、室温については室内機１の吹き出し温度や、室内熱交換器の配管温度によって間接的に求めても良いことは言うまでもない。 In each of the above-described embodiments, the air direction is controlled until the room temperature matches the set temperature. However, the room temperature is indirectly determined based on the blowing temperature of the indoor unit 1 and the piping temperature of the indoor heat exchanger. Needless to say.
　本発明にかかる空気調和機は、結露防止とともに、撮像装置の設置位置の制限を無くし、さらには省電力化も可能であり、空気調和機だけでなく、換気扇、空気清浄機などにも適用可能である。 The air conditioner according to the present invention can prevent condensation, eliminate the restriction of the installation position of the imaging device, and further save power, and can be applied not only to an air conditioner but also to a ventilation fan, an air purifier, etc. It is.
