【考案の詳細な説明】
この考案は空調機器に湿度調節機能を持たせる
ために用いられる湿度検知装置に関するものであ
る。[Detailed Description of the Invention] This invention relates to a humidity detection device used for providing a humidity control function to air conditioning equipment.
従来湿度センサーは常時湿度検知部が空気に触
れ、空気中の含水量に応じた電気信号を送るよう
に構成されている。しかしながら空気中の水分だ
けでなく、各種の汚染物質にも常時触れているた
め、検知器の感湿面が汚染されて適正な指示値が
得られなくなつたり、寿命時記が短かくなる等の
欠点があつた。 Conventional humidity sensors are configured so that the humidity detection part is constantly in contact with the air and sends an electrical signal depending on the moisture content in the air. However, since it is constantly in contact with not only moisture in the air but also various pollutants, the moisture-sensitive surface of the detector becomes contaminated, making it impossible to obtain appropriate readings and shortening the lifespan. There were some shortcomings.
この考案は上述した従来の欠点を改善するため
になされたものであり、湿度を検知する空気を断
続的に採取する分取方式により湿度センサーの寿
命を長く維持するように構成した湿度検知装置を
提供するものである。 This idea was made in order to improve the above-mentioned drawbacks of the conventional technology, and it is a humidity detection device configured to maintain a long lifespan of the humidity sensor using a preparative method that intermittently samples the air for humidity detection. This is what we provide.
以下、この考案による実施例を添付した図面を

空気を湿度センサー１にて検知するようになつて
いる。 Hereinafter, embodiments of this invention will be described in detail with reference to the accompanying drawings. A humidity sensor 1 detects the moisture content in the air and displays it on a predetermined display device (not shown). The humidity sensor 1 is surrounded by a housing 2, and the humidity sensor 1 detects air sampled through openings 2a formed on the left and right sides of the housing 2.
上記筐体２の左右開口部２ａは、円板状の一部
に切欠部３ａを形成した開閉円板３が回転軸４を

つている。上記開閉円板３の回転軸４はモーター
５に接続され、所定の回転が与えられている。 The left and right openings 2a of the casing 2 are configured to open and close intermittently when an opening/closing disc 3 having a notch 3a formed in a disc-shaped portion rotates via a rotating shaft 4. The rotating shaft 4 of the opening/closing disc 3 is connected to a motor 5 and is given a predetermined rotation.
以上詳細に説明したように、この考案による湿

れ換えに要する時間を考慮して、約３分に一度開
口部２ａが開くように適宜設定されるのが望まし
い。 As explained in detail above, in the humidity detection device according to this invention, first, when the motor 5 rotates, the shaft 4
The opening/closing disc 3 begins to rotate via. At this time, the rotation of the motor 5 depends on the function of the humidity sensor 1, but is determined by the shape of the humidity sensor 1, the volume of the housing 2 which is a container, and the size of the opening 2a for collecting the detected air. In consideration of the time required to exchange the air in the housing 2, it is desirable to set the opening 2a to open approximately once every three minutes.
すなわち、最近の湿度センサー１は数秒で検知
空気の湿度に反応するので、筐体２をあまり大き
くしなければ検知空気の入れ換え時間は適当な流
速があれば10秒程度で充分である。従つて、入れ
換え時間を10秒とした場合、従来の検知空気に常
時露出してた場合の湿度センサーに比べて、湿度
センサーの検知部が汚染される機会は10/60×３
＝1/18となり、汚染に対する寿命が18倍に延長さ
れることになる。 That is, since the recent humidity sensor 1 reacts to the humidity of the detected air in a few seconds, if the casing 2 is not too large, the time for replacing the detected air is about 10 seconds, provided there is an appropriate flow rate. Therefore, if the replacement time is 10 seconds, the chance of the detection part of the humidity sensor becoming contaminated is 10/60 x 3 compared to a humidity sensor that is constantly exposed to the conventional detection air.
= 1/18, meaning that the lifespan against contamination will be extended 18 times.
上述したように、この考案によれば、湿度セン
サーによる検知空気を間欠的に採取するように構
成されているから、湿度センサーが外部空気と接
触する時間が短かくなり、汚染による寿命が伸び
る効果を得ることができるものである。 As mentioned above, this invention is configured so that the air detected by the humidity sensor is sampled intermittently, which shortens the time the humidity sensor is in contact with external air, thereby extending its lifespan due to contamination. This is something that can be obtained.
