用されている。Technical Background of the Invention Humidity sensing devices detect atmospheric humidity, for example, and devices that apply various principles are known, but humidity sensors that utilize changes in electrical impedance are small, robust, and easy to handle. It is used to control air conditioning equipment, microwave ovens, and other equipment.
ところが湿度センナは感湿部の大きさが数１１ｊｌ１以
内に形成されており、接触する大気は非常に局所的なも

れがある。さらに湿度センサは防塵のために感湿部を通
気性の外囲器で覆っており、感温部周囲の空気が滞留し
て変動する部屋の湿度な迅速に検知しないことがある。However, in the humidity sensor, the size of the humidity sensing part is formed within several 11jl1, and the atmospheric air it comes into contact with is very localized, so there is a risk that the humidity of the atmosphere cannot be quickly determined. Furthermore, the humidity sensor has its humidity sensing part covered with a breathable envelope to prevent dust, and the air around the temperature sensing part may stagnate, making it impossible to quickly detect the fluctuating humidity of the room.
発明の目的
この発明は以上の欠点を除去する感湿装置を得るもので
ある。OBJECTS OF THE INVENTION The present invention provides a moisture sensing device which eliminates the above-mentioned drawbacks.
発明の概要

からなる感湿装置にある。Summary of the Invention In other words, the present invention provides a humidity sensor consisting of a humidity sensing section and an envelope containing the humidity sensing section; There is a humidity sensing device consisting of a container.
外囲器は通気壁を有して外囲器外側の空気が内部に通流
可能にされるが、通気壁を湿度センサの振動方向に面す

器内外の空気の循環を高める。これにより、空気が外囲
器内部に滞留することがな（ｆｃす、湿度変動に対して
迅速な応答が可能になる。The envelope has a ventilation wall to allow air from outside the envelope to flow inside, but the ventilation wall can be oriented to face the vibration direction of the humidity sensor to allow air to flow into the envelope. Promote inflow and increase air circulation inside and outside the envelope. This prevents air from stagnation inside the envelope and enables quick response to humidity fluctuations.

で小形に形成することができる。In Figure 1, /! ii! The envelope 00) of the variable sensor Fl) is made of a mold made of resin such as Ebogishi or aluminum, and houses a moisture sensing part (11) therein. There are ventilation walls (1) on both sides of the envelope (1).
2 or number 10. It is surrounded by a mesh having a large number of U-diameter ventilation holes, allowing air to circulate inside and outside the envelope. Two upper air extraction lead wires r131H extend from the humidity sensing portion (11) and are drawn out through the wall of the envelope 00) through the elbows. On the opposite side to the direction in which the lead wires are pulled out, an envelope mounting portion 09 is integrally formed with the envelope. 1 at the tip (16) of the envelope attachment part (15).
1y, a tag (1η) is provided and can be arbitrarily attached to the wall of the equipment or air conditioning room.Now, this mounting hole (17
An ultrasonic vibrator is provided as a vibration generator (18) on the outer surface of the envelope mounting portion between the outer earpiece and the outer earpiece (10). 74 strain or magnetostriction, which produces minute vibrations at, for example, 20 KHz. Symbol (1'j (2(+1) indicates the lead wire for power supply. This vibration is transmitted to the envelope, vibrates the envelope, disturbs the surrounding atmosphere, and changes the atmosphere inside and outside the envelope. Forces circulation and eliminates atmospheric stagnation inside the envelope.Ultrasonic waves are more effective with minute energy, but they are used at a vibration frequency of audible 1, which is within the range where it is not jarring even at a river wave number. Continuous vibration or pulsed vibration may be used, and constant vibration is continued.1.According to this embodiment, since the vibrator is integrated into the envelope, it is easy to apply vibration and it can be formed compactly. can.
