Description

【０００１】
【発明の属する技術分野】
本発明は、赤外線量に基づいて制御される空気調和機およびその動作方法に関し、特に、室内に空気調和のために据付けられる空気調和機が赤外線量を測定することによって在室者数とそれらの位置変化にしたがって自動に制御されるようにする、赤外線量に基づいて制御される空気調和機およびその動作方法に関する。
【０００２】
【従来の技術】
最近、大規模の食堂や教室などで空気調和のための床置き型空気調和機の据付が急増している。前記床置き型空気調和機は室内の一空間に位置して室内の空気が調和されるように冷／暖房の機能を行う。しかし、この場合、床置き型空気調和機は特定空間に据付けられているため、大規模の空間の室内空気を均一且つ快適に調和させられないという問題点があった。
【０００３】
例えば、室内を冷房させるために室内にエアコンが据付けられた場合、図６に示すように、空気調和機に付着された温度計を用いて室内温度を測定（Ｓ１）し、前記測定された室内温度を使用者が予め設定しておいた基準温度と比較（Ｓ２）し、前記室内温度が基準温度より低い場合は吐出量を減少（Ｓ３）させ、室内温度が基準温度より高い場合は吐出量を増加（Ｓ４）させる。
【０００４】
したがって、図７に示すように、空気調和機１が室内の特定空間ａに据付けられた場合、前記空気調和機１は前記特定空間ａの室内温度だけを測定し、これを空気調和機に設定された基準温度と比較し、この比較結果に基づいて駆動方式を制御するようになる。例えば、前記床置き型空気調和機１が冷房機能を行うエアコンであり、測定された室内温度が基準温度より低いと、前記床置き型空気調和機は冷房機能を中止し、測定された室内温度が基準温度より高い場合は、冷房機能を強化するようになる。つまり、特定空間ａの温度だけに基づいてその冷房機能が制御され、他の空間ｂ、ｃ、ｄの室内温度は認知できないため、室内空気を均一に調和させることができなかった。
【０００５】
また、在室者数の増加に伴って室内温度も増加することになる。しかし、従来の床置き型空気調和機は、前述のように特定空間ａの室内温度だけを認知し、それに基づいて制御されるため、仮に、前記在室者がａ空間でないｂ或いはｃ空間で増加する場合、これを認知できず室内温度を続けて上昇させてしまい、空気調和機が作動されているにも関わらず使用者は快適さを感じられなくなる。
【０００６】
【発明が解決しようとする課題】
本発明は、前記問題点に鑑みてなされたものであり、室内の空気調和のために据付けられる空気調和機に赤外線探知センサを付着し、前記赤外線探知センサによって探知された赤外線量に基づいて空気調和機の吐出を制御することによって在室者数などの変化に対応して有効且つ快適に空気調和可能な、赤外線量に基づいて制御される空気調和機およびその動作方法を提供することにその目的がある。
【０００７】
【課題を解決するための手段】
前記課題を解決すべく本発明による、赤外線量に基づいて制御される空気調和機の特徴によれば、熱交換器および送風機が内蔵されたキャビネットと、前記キャビネットに結合されて室内空気が吸入および吐出されるフロントパネルと、前記フロントパネルに設けられた左右移動ルーバーに付着されて前記室内の赤外線量を測定する赤外線探知センサと、前記赤外線探知センサから探知された赤外線量およびその分布にしたがって空気調和機の吐出を制御するマイコンと、前記赤外線探知センサが探知した室内の複数空間別赤外線量に関するデータが貯蔵されるメモリ部と、を含めて構成され、前記マイコンは、前記メモリ部に貯蔵された各空間別赤外線量と現在測定される各空間別赤外線量を比較し、それに基づいて空気調和機の吐出を制御することを特徴とする。
【０００８】
また、本発明による赤外線量に基づいて制御される空気調和機動作方法の特徴によれば、空気調和機駆動中に室内複数空間の赤外線量が測定される第１段階と、前記第１段階で測定された赤外線量に関する情報が各空間別に貯蔵される第２段階と、前記第２段階で貯蔵された赤外線量に関する情報に基づいて空気調和機の吐出が制御される第３段階と、からなる。
【０００９】
【発明の実施の形態】
以下、本発明の好ましい実施形態を添付図面を参照して詳細に説明する。
本発明の一実施形態による床置き型空気調和機１００は、図１に示すように、熱交換器および送風機が内蔵されて吸入された空気を熱交換し、吐出させるキャビネット１０と、前記キャビネット１０に結合され、前記キャビネット１０に空気を吸入させるための吸入口と前記キャビネット１０で熱交換された空気を吐出させるための吐出口が備えられるフロントパネル２０と、前記フロントパネル２０の一側、つまり前記フロントパネル２０に取り付けられる左右移動ルーバー２１に付着される赤外線探知センサ３０と、前記赤外線探知センサ３０から探知された室内の複数空間の赤外線量に基づいて前記空気調和機１００の吐出を制御するマイコンと、から構成される。
【００１０】
特に、前記空気調和機１００の左右回転ルーバー２１に付着された赤外線探知センサ３０は、前記左右回転ルーバー２１とともに左右に移動しながら前記室内の複数空間の赤外線量を測定する。前記マイコンは、前記赤外線探知センサ３０から測定された赤外線量に基づいて室内の複数空間に吐出される風量と風向を調節する。
図２は本発明による床置き型空気調和機１００の内部構成を示す図である。
【００１１】
図２に示すように、本発明による床置き型空気調和機１００は、左右回転ルーバーに付着されて前記空気調和機１００の駆動とともに室内の複数空間の赤外線量を測定する赤外線探知センサ３０と、前記赤外線探知センサ３０から探知された複数空間の赤外線量に関するデータが各空間別に貯蔵されるメモリ部４０と、前記赤外線探知センサ３０から現在測定される赤外線量と前記メモリ部４０に貯蔵された既存の赤外線量を相互比較し、それに基づいて空気調和機の吐出される風量と風向などを制御できるように左右回転ルーバーの駆動モータＭと連結されたマイコン５０と、前記マイコン５０によってその動作が制御される警報器６０と、から構成される。
【００１２】
特に、前記マイコン５０は、前記赤外線探知センサ３０から測定される赤外線量を各空間ごとに比較して吐出を制御したり、現在測定される赤外線量を既存に測定された赤外線量と比較して吐出を制御したりする。
すなわち、前記空気調和機１００が初めて駆動されると、前記左右回転ルーバー２１に付着された赤外線探知センサ３０は、図３に示すように、前記空気調和機１００の据付けられたａ空間を始めとして室内の複数空間ｂ、ｃ、ｄ、ｅ、ｆ、ｇに存在する赤外線量をスキャニングして探知する。
【００１３】
このとき、前記マイコン５０は、前記複数個所の空間別赤外線量の大小を比較し、それに基づいて前記駆動モータＭを制御し、また、必要に応じて空気調和機１００の吐出量を制御する。例えば、本発明による空気調和機が冷風機として動作する空気調和機の場合、本発明による空気調和機１００のマイコン５０は、前記複数空間のうち相対的に大きい赤外線量が測定された空間に吐出風が伝達されるように吐出方向を調節しなければならないが、このため、前記駆動モータＭを制御して前記左右回転ルーバー２１を調節する。また、必要に応じて前記マイコン５０は前記大きい赤外線量が測定された空間に向かって吐出量を増加させることもできる。
【００１４】
一方、前記探知された各空間の赤外線量は各々前記メモリ部４０に貯蔵される。その後、前記床置き型空気調和機１００が続けて動作すると、前記左右回転ルーバー２１の駆動とともに前記赤外線探知センサ３０は前記メモリ部４０に赤外線量に関するデータが貯蔵された各空間別赤外線量を再び探知する。このとき、前記マイコン５０は前記現在探知された赤外線量と前記メモリ部４０に貯蔵された既存の赤外線量が同一か否か比較する。
【００１５】
例えば、前記ｃ空間に位置する在室者数が増加し、このｃ空間の赤外線量が増加する場合、前記赤外線探知センサ３０は前記増加した赤外線量を探知するようになる。このように前記メモリ部４０に貯蔵された既存の赤外線量より前記赤外線探知センサ３０から現在測定された赤外線量が増加すると、前記マイコン５０は吐出量を増加すると同時に、前記左右回転ルーバーを調節して前記床置き型空気調和機の吐出方向が前記ｃ空間に向かうように制御する。
【００１６】
一方、前記ｃ空間に位置する在室者数が減少した場合、前記赤外線探知センサ３０は減少した赤外線量を感知し、前記マイコン５０は、前記メモリ部４０に貯蔵された既存の赤外線量より前記赤外線探知センサ３０から現在測定された赤外線量が減少したことを感知し、吐出量を減少させる。また、前記マイコン５０は、前記左右回転ルーバー２１を調節して本発明による空気調和機の吐出方向が前記ｃ空間に向かわないように制御する。
【００１７】
さらに、前記赤外線探知センサ３０は、赤外線量を測定するに際して室内の複数空間の赤外線量を測定するため、図３の空間のうちｉ空間の赤外線量を測定することができる。前記マイコン５０は、前記赤外線探知センサ３０を通じて持続的に赤外線量が測定されることを感知する途中、前記ｉ空間で赤外線が探知されたことを感知すると、空気調和機１００に装着された警報器６０に動作信号を伝送して警報器６０を作動させる。
【００１８】
ここで、前記マイコン５０が赤外線量の存在有無を確認できる空間は前記複数空間のうち任意のいずれの空間でもあり得る。したがって、使用者が必要に応じて任意の空間を特定すると、前記マイコン５０は前記特定した空間の赤外線存在有無を確認し警報器６０を動作させることができる。
例えば、使用者は、泥坊の侵入が容易なベランダ或いは窓側の空間を前記特定空間として指定し、前記特定空間で赤外線が感知された場合、前記空気調和機１００に装着された警報器６０が動作されるようにすることができる。
【００１９】
図４は、本発明による赤外線量に基づいて制御される空気調和機の動作方法の第１実施形態を示す図である。
図４を参照すれば、まず、第１１段階（Ｓ１１）で、空気調和機の左右回転ルーバーに付着された赤外線探知センサが前記左右回転ルーバーの駆動とともに室内の複数空間の赤外線量を測定する。
第１２段階（Ｓ１２）で、前記メモリ部は前記第１１段階で測定された赤外線量に関する情報を各空間別に貯蔵する。このとき、前記赤外線量は各空間ごとに分離されて貯蔵されるため、前記マイコンは各空間別赤外線量を認知することができる。
【００２０】
第１３段階（Ｓ１３）で、前記マイコンは前記第１１段階で測定された複数空間の赤外線量の大小を比較する。
第１４段階（Ｓ１４）で、前記マイコンは前記第１３段階の比較結果に基づいて相対的に多い赤外線量が測定された空間に向かって左右回転ルーバーを調節し、必要に応じて吐出量を増加させることもできる。
一方、第１５段階（Ｓ１５）で、前記マイコンは前記第１１段階で赤外線探知センサが特定空間、例えば、ベランダ或いは窓側で赤外線を測定したか確認する。
【００２１】
仮に、前記第１５段階で前記赤外線探知センサが特定空間の赤外線を探知しなかった場合、前記マイコンは続けて前記赤外線探知センサの特定空間での赤外線測定を確認する。一方、前記第１５段階で前記赤外線探知センサが特定空間の赤外線を探知した場合、前記マイコンは第１６（Ｓ１６）段階で警報器を作動させる。
図５は、本発明による赤外線量に基づいて制御される空気調和機の動作方法の第２実施形態を示す図である。
【００２２】
図５を参照すれば、まず、第２１段階（Ｓ２１）で、空気調和機の左右回転ルーバーに付着された赤外線探知センサが前記左右回転ルーバーの駆動とともに室内の複数空間の赤外線量を測定する。
第２２段階（Ｓ２２）で、前記メモリ部は前記第２１段階で測定された赤外線量に関する情報を各空間別に貯蔵する。このとき、前記赤外線量は各空間ごとに分離されて貯蔵されるため、前記マイコンは各空間別赤外線量を認知することができる。
【００２３】
第２３段階（Ｓ２３）で、前記赤外線探知センサは前記空気調和機の駆動とともに再び前記室内の複数空間の赤外線量を測定する。
第２４段階（Ｓ２４）で、前記マイコンは前記第２３段階で現在測定される赤外線量と前記第２２段階で貯蔵された既存の赤外線量が同一か比較する。仮に、同一であると、本発明による空気調和機の制御方法は前記第２３段階に戻る。
一方、前記第２４段階で、現在測定された赤外線量と既存赤外線量が同一でないと判断されると、第２５段階（Ｓ２５）で、前記マイコンは、現在測定された赤外線量が既存赤外線量より多いか判断する。
【００２４】
前記第２５段階の判断結果、現在測定された赤外線量が既存赤外線量より多いと、第２６段階（Ｓ２６）で、前記マイコンは前記空気調和機の吐出量を増加させ、前記第２３段階で測定された赤外線量をメモリ部に貯蔵する。
一方、前記第２５段階の判断結果、現在測定された赤外線量が既存赤外線量より少ないと、第２７段階（Ｓ２７）で、前記マイコンは前記空気調和機の吐出量を減少させ、前記第２３段階で測定された赤外線量をメモリ部に貯蔵する。
【００２５】
【発明の効果】
以上のように構成される本発明の赤外線量に基づいて制御される空気調和機およびその動作方法は、室内に空気調和のために据付けられる空気調和機の左右回転ルーバーに赤外線探知センサを付着した後、前記赤外線探知センサが前記左右回転ルーバーの駆動とともに室内の複数空間の赤外線量を測定した結果を各空間別に貯蔵し、次いで、前記空気調和機駆動中に探知した室内の赤外線量を前記貯蔵された赤外線量と比較し、それに基づいて空気調和機の吐出量が調節されるようにすると同時に、前記赤外線探知センサによって測定された各空間の赤外線量を相互比較し、その大小に基づいて空気調和機の吐出方向が調節されるようにすることによって、在室者数の増減にしたがって自動的に空気調和機の吐出が制御されるようにし、使用者の快適度を向上させ得る効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner controlled based on the amount of infrared rays and a method of operating the same, and more particularly, the air conditioner installed for air conditioning in a room measures the amount of infrared rays and the number of people in the room. The present invention relates to an air conditioner controlled based on an amount of infrared rays, and an operation method thereof, which are automatically controlled according to a change in position.
[0002]
[Prior art]
Recently, the installation of floor-mounted air conditioners for air conditioning in large-scale dining rooms and classrooms has increased rapidly. The floor-standing air conditioner is located in a room and performs a cooling / heating function so that indoor air is harmonized. However, in this case, since the floor-type air conditioner is installed in a specific space, there is a problem that indoor air in a large-scale space cannot be harmonized uniformly and comfortably.
[0003]
For example, when an air conditioner is installed in the room to cool the room, the room temperature is measured (S1) using a thermometer attached to the air conditioner as shown in FIG. The temperature is compared with a reference temperature preset by the user (S2). When the room temperature is lower than the reference temperature, the discharge amount is decreased (S3), and when the room temperature is higher than the reference temperature, the discharge amount. Is increased (S4).
[0004]
Therefore, as shown in FIG. 7, when the air conditioner 1 is installed in a specific space a in the room, the air conditioner 1 measures only the indoor temperature of the specific space a and sets this as the air conditioner. The driving method is controlled based on the comparison result. For example, if the floor-standing air conditioner 1 is an air conditioner that performs a cooling function, and the measured indoor temperature is lower than a reference temperature, the floor-standing air conditioner stops the cooling function and the measured indoor temperature When is higher than the reference temperature, the cooling function is enhanced. That is, the cooling function is controlled based only on the temperature of the specific space a, and the indoor temperatures of the other spaces b, c, and d cannot be recognized, so the indoor air cannot be harmonized uniformly.
[0005]
In addition, the room temperature increases as the number of people in the room increases. However, since the conventional floor-standing type air conditioner recognizes only the indoor temperature of the specific space a as described above and is controlled based on it, it is assumed that the occupant is in the b or c space that is not the a space. If it increases, this cannot be recognized and the room temperature continues to rise, and the user cannot feel comfort despite the air conditioner being activated.
[0006]

At this time, the microcomputer 50 compares the amount of infrared light according to space at the plurality of locations, controls the drive motor M based on the magnitude, and controls the discharge amount of the air conditioner 100 as necessary. For example, in the case where the air conditioner according to the present invention is an air conditioner that operates as a cold air blower, the microcomputer 50 of the air conditioner 100 according to the present invention discharges into a space where a relatively large amount of infrared rays is measured among the plurality of spaces. The discharge direction must be adjusted so that the wind is transmitted. For this reason, the drive motor M is controlled to adjust the left-right rotation louver 21. Further, if necessary, the microcomputer 50 can increase the discharge amount toward the space where the large infrared ray amount is measured.
[0014]
Meanwhile, the detected infrared amount of each space is stored in the memory unit 40. Thereafter, when the floor-standing air conditioner 100 continues to operate, the infrared detection sensor 30 again returns the infrared amount for each space in which data relating to the amount of infrared rays is stored in the memory unit 40 as the left and right rotating louvers 21 are driven. Detect. At this time, the microcomputer 50 compares whether the currently detected infrared ray amount is the same as the existing infrared ray amount stored in the memory unit 40.
[0015]
For example, when the number of occupants located in the c space increases and the amount of infrared rays in the c space increases, the infrared detection sensor 30 detects the increased amount of infrared rays. As described above, when the amount of infrared rays currently measured from the infrared detection sensor 30 increases from the existing amount of infrared rays stored in the memory unit 40, the microcomputer 50 increases the discharge amount and simultaneously adjusts the left and right rotation louvers. The discharge direction of the floor-standing air conditioner is controlled so as to go to the c space.
[0016]
On the other hand, when the number of occupants located in the c space decreases, the infrared detection sensor 30 senses the decreased amount of infrared rays, and the microcomputer 50 determines the amount of existing infrared rays stored in the memory unit 40 from the existing infrared amount. The infrared detection sensor 30 detects that the amount of infrared rays currently measured has decreased, and reduces the discharge amount. The microcomputer 50 controls the left and right rotating louvers 21 so that the discharge direction of the air conditioner according to the present invention does not go to the c space.
[0017]
Furthermore, since the infrared detection sensor 30 measures the amount of infrared in a plurality of indoor spaces when measuring the amount of infrared, it can measure the amount of infrared in the i space in the space of FIG. When the microcomputer 50 senses that the amount of infrared rays is continuously measured through the infrared detection sensor 30 and senses that infrared rays have been detected in the i space, the microcomputer 50 has an alarm device attached to the air conditioner 100. The operation signal is transmitted to 60 and the alarm device 60 is activated.
[0018]
Here, the space where the microcomputer 50 can confirm the presence or absence of the amount of infrared rays may be any space among the plurality of spaces. Therefore, when the user specifies an arbitrary space as necessary, the microcomputer 50 can check the presence or absence of infrared rays in the specified space and operate the alarm device 60.
For example, the user designates a veranda or a window-side space where mud boys can easily enter as the specific space, and when infrared light is detected in the specific space, the alarm device 60 attached to the air conditioner 100 is Can be operated.
[0019]
FIG. 4 is a diagram showing a first embodiment of the operation method of the air conditioner controlled based on the amount of infrared rays according to the present invention.
Referring to FIG. 4, first, in an eleventh step (S11), an infrared detection sensor attached to the left and right rotating louvers of the air conditioner measures the amount of infrared rays in a plurality of spaces in the room along with the driving of the left and right rotating louvers.
In step 12 (S12), the memory unit stores information on the amount of infrared rays measured in step 11 for each space. At this time, since the infrared ray amount is separated and stored for each space, the microcomputer can recognize the infrared ray amount for each space.
[0020]
In the thirteenth step (S13), the microcomputer compares the infrared light amounts of the plurality of spaces measured in the eleventh step.
In the 14th step (S14), the microcomputer adjusts the left / right rotation louver toward the space where the relatively large amount of infrared rays is measured based on the comparison result of the 13th step, and increases the discharge amount as necessary. It can also be made.
On the other hand, in step 15 (S15), the microcomputer checks in step 11 whether the infrared detection sensor has measured infrared light in a specific space, for example, on the veranda or the window side.
[0021]
If the infrared detection sensor does not detect infrared in the specific space in the fifteenth step, the microcomputer continues to check infrared measurement in the specific space of the infrared detection sensor. On the other hand, when the infrared detection sensor detects infrared rays in a specific space in the fifteenth step, the microcomputer activates an alarm in the sixteenth (S16) step.
FIG. 5 is a diagram showing a second embodiment of the operation method of the air conditioner controlled based on the amount of infrared rays according to the present invention.
[0022]
Referring to FIG. 5, first, in a 21st step (S21), the infrared detection sensor attached to the left and right rotating louvers of the air conditioner measures the amount of infrared rays in a plurality of indoor spaces along with the driving of the left and right rotating louvers.
In step 22 (S22), the memory unit stores information on the amount of infrared rays measured in step 21 for each space. At this time, since the infrared ray amount is separated and stored for each space, the microcomputer can recognize the infrared ray amount for each space.
[0023]
In step 23 (S23), the infrared detection sensor again measures the amount of infrared rays in the plurality of indoor spaces as the air conditioner is driven.
In step 24 (S24), the microcomputer compares the amount of infrared light currently measured in step 23 with the existing amount of infrared light stored in step 22. If they are the same, the control method of the air conditioner according to the present invention returns to the twenty-third stage.
On the other hand, if it is determined in step 24 that the currently measured infrared ray amount and the existing infrared ray amount are not the same, in step 25 (S25), the microcomputer determines that the currently measured infrared ray amount is greater than the existing infrared ray amount. Judge whether there are many.
[0024]
As a result of the determination in the 25th step, if the currently measured infrared ray amount is larger than the existing infrared ray amount, the microcomputer increases the discharge amount of the air conditioner in the 26th step (S26), and the measurement is performed in the 23rd step. The amount of infrared rays is stored in the memory unit.
On the other hand, if the currently measured infrared light amount is smaller than the existing infrared light amount as a result of the determination in the 25th step, the microcomputer decreases the discharge amount of the air conditioner in the 27th step (S27), and the 23rd step The amount of infrared rays measured in step 1 is stored in the memory unit.
