Abstract

<P>PROBLEM TO BE SOLVED: To prevent malfunction of an air conditioner caused by such a fact that in operation start control for the existing air conditioner by an infrared pyroelectric sensor, the air conditioner starts to operate only by minimal movement of a heat source due to action outside of a door in one detection area. <P>SOLUTION: The infrared pyroelectric sensor 2 detects more than one human activity, thereby it is determined that a person walks in a room and starts activity. Accordingly, it is possible to prevent such a malfunction that the air conditioner starts to operate only by the minimal movement of the heat source. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

本発明は、赤外線焦電センサーを搭載し、自動的に運転を開始することができる空気調和機に関するものである。   The present invention relates to an air conditioner equipped with an infrared pyroelectric sensor and capable of automatically starting operation.

従来、この種の空気調和機は、赤外線焦電センサーが熱源を検知すれば自動的に運転を始めるようになっている（例えば、特許文献１参照）。   Conventionally, this type of air conditioner automatically starts operation when an infrared pyroelectric sensor detects a heat source (see, for example, Patent Document 1).

図３は、特許文献１に記載された従来の空気調和機１に設置された赤外線焦電センサー２と室内３の検出エリア４の配置図である。図４は赤外線焦電センサー２とマイコン５との接続図である。赤外線センサー２は、マイコン５に信号を送ることで、空気調和機１を制御している。
特開平９−１７８２５９号公報 FIG. 3 is a layout diagram of the infrared pyroelectric sensor 2 installed in the conventional air conditioner 1 described in Patent Document 1 and the detection area 4 in the room 3. FIG. 4 is a connection diagram between the infrared pyroelectric sensor 2 and the microcomputer 5. The infrared sensor 2 controls the air conditioner 1 by sending a signal to the microcomputer 5.
Japanese Patent Laid-Open No. 9-178259

しかしながら、前記従来の構成では、空気調和機１に取り付けられた赤外線焦電センサー２は、室内３のそれぞれの検出エリア３を有しており、例えばエリア４−Ａを検出する赤外線焦電センサー２−Ａが熱源を検出すると人の活動があったと認識するため、空気調和機１は運転を始める。この場合、１つのエリア内の扉６の外で何らかの熱源の動きがあった場合でも人が活動したと判断されてしまうため空気調和機１は、運転状態になるという課題を有していた。   However, in the conventional configuration, the infrared pyroelectric sensor 2 attached to the air conditioner 1 has the respective detection areas 3 in the room 3, and for example, the infrared pyroelectric sensor 2 for detecting the area 4-A. When A detects a heat source, it recognizes that there was human activity, so the air conditioner 1 starts operation. In this case, the air conditioner 1 has a problem of being in an operating state because it is determined that a person has been active even if there is any movement of a heat source outside the door 6 in one area.

本発明は、前記従来の課題を解決するもので、２つ以上の検出エリアを反応させるような大きな活動をすることによって、運転を開始することができる空気調和機を提供することを目的とする。   This invention solves the said conventional subject, and it aims at providing the air conditioner which can start an operation | movement by performing big activity which makes two or more detection areas react. .

前記従来の課題を解決するために、本発明の空気調和機は、赤外線焦電センサーの検出エリアが２個以上反応することで人が室内での活動を始めたと検出し空気調和機を停止状態から運転状態へと切り替える。   In order to solve the above-mentioned conventional problems, the air conditioner of the present invention detects that a person has started an indoor activity by reacting two or more detection areas of the infrared pyroelectric sensor, and stops the air conditioner. Switch from to the operating state.

これによって、空気調和機は、ほとんど活動のない室内で自動的に運転を始める誤動作を防止することができる。   As a result, the air conditioner can prevent a malfunction that automatically starts in a room with little activity.

本発明の空気調和機は、２個以上の赤外線焦電センサーが人を検知したときに運転を開始することができる。   The air conditioner of the present invention can start operation when two or more infrared pyroelectric sensors detect a person.

本発明は、空気調和機が取り付けられた赤外線焦電センサーからの人検知信号を受信し、２個以上の検出信号を受信したことにより人の活動として検出することを有する。   The present invention includes detecting a human detection signal from an infrared pyroelectric sensor to which an air conditioner is attached, and detecting a human activity by receiving two or more detection signals.

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。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

（実施の形態１）
図１は、本発明の第１の実施の形態における赤外線焦電センサー２の室内の検出エリア３を示す。図２は、赤外線焦電センサー２とマイコン５の接続を示す構成図である。 (Embodiment 1)
FIG. 1 shows a detection area 3 in the room of the infrared pyroelectric sensor 2 according to the first embodiment of the present invention. FIG. 2 is a configuration diagram showing the connection between the infrared pyroelectric sensor 2 and the microcomputer 5.

空気調和機１に設置されている３個の赤外線焦電センサー２は、それぞれ室内エリア４−Ａ，Ｂ，Ｃにおける熱源としての人の活動を検出している。各赤外線焦電センサー２が人検出をすれば制御基板内のマイコン５に人検出の信号を送信する。空気調和機１が運転停止状態においても赤外線焦電センサー２からの信号を受信状態とし、人が室内３に入室し活動を始めることで、エリア４−Ａからの検出する信号だけでなく、エリア４−Ｂからの人検出信号もマイコンが受信したときに初めて人が室内で活動していると判断し、空気調和機１を運転させる。２つ以上のエリア４からの検出信号により人の活動を判断することで扉６の外での僅かな熱源による反応による空気調和機１の誤動作を防止することができる。   The three infrared pyroelectric sensors 2 installed in the air conditioner 1 detect human activities as heat sources in the indoor areas 4-A, B, and C, respectively. When each infrared pyroelectric sensor 2 detects a person, it transmits a person detection signal to the microcomputer 5 in the control board. Even when the air conditioner 1 is in the operation stop state, the signal from the infrared pyroelectric sensor 2 is set to the reception state, and when the person enters the room 3 and starts the activity, not only the signal detected from the area 4-A but also the area When the microcomputer receives the human detection signal from 4-B, it is determined that the person is active in the room for the first time, and the air conditioner 1 is operated. By judging human activity based on detection signals from two or more areas 4, malfunction of the air conditioner 1 due to a reaction caused by a slight heat source outside the door 6 can be prevented.

以上のように、本発明は、複数の赤外線焦電センサーを搭載した空気調和機以外の機器の用途にも適用できる。   As mentioned above, this invention is applicable also to the use of apparatuses other than the air conditioner which mounts a some infrared pyroelectric sensor.
