ンサーを接続することが試みられた。Japanese Patent Application No. Sho 61-185026, which is a prior art to the present invention, describes a device in which a heat generating body is integrated with a moisture absorbing body. This material had a release speed several to several ten times faster than the moisture absorption speed. Therefore, it was required to heat the heating element intermittently for a short period of time, and an attempt was made to connect an electrical resistance type moisture content sensor.
即ち、吸湿体の含水率が上がると抵抗が小さくなって、

点があった。In other words, as the moisture content of the moisture absorber increases, the resistance decreases,
We tried a control method in which the heating element is turned on and turned off when the moisture content reaches a predetermined level, but in the AC electric field, the frequency became unstable due to ionization of the hygroscopic filler due to electrolysis, and the set value and detection results were There was some variation. Therefore, if the frequency is converted to a high frequency using a frequency converter, the detection accuracy improves, but there is a drawback that the device is expensive and large-scale.

しかして、発熱体(2)に通電し、放湿体(11の背面
を加熱してここから放湿するのであるが、吸湿体(1)

になり、水分の蒸発が少なくなると水分蒸発による気化
熱の放出が少なくなり、吸湿体(1)は昇温しで高温に
なる。Then, the heating element (2) is energized to heat the back surface of the moisture radiator (11) and radiate moisture from there, but the moisture absorber (1)
When the water content is high, evaporation occurs actively, so the heat of vaporization is taken away, and the temperature of the moisture absorbing body (1) does not rise above the set value. However, as a result of continuous moisture release, the hygroscopic body (1) has a low moisture content, and as moisture evaporates less, the heat of vaporization due to moisture evaporation is released less, and the hygroscopic body (1) becomes hot. .
吸湿体(11が所定の温度に達すると温度センサ(3)

吸湿体(1)は低含水率であるので室内の湿気を徐々に
取込み、室内を除湿する。When the moisture absorber (11) reaches a predetermined temperature, the temperature sensor (3)
is activated, the solid state relay (SSR) is turned off, and the power to the heating element (11) is stopped. In this state, the moisture absorber (1) has a low moisture content, so it gradually takes in moisture from the room and dehumidifies the room. do.
吸湿体(1)はその大きさと室内の湿度状態により吸湿
能力が衰える時間は異なるが95%R11の高湿度環境
下でも数時間から1日程度である。The time for the moisture absorbing ability of the moisture absorbing body (1) to decline varies depending on its size and indoor humidity condition, but it takes from several hours to about one day even in a high humidity environment of 95% R11.
一方、吸湿体fl)が発熱体(2)の通電による放湿で
低含水率になり、賦活するのは数分〜1時間あれば充分
であり、所定の含水率以下になればそれ以上加熱する必
要はないので前記のように通電を停止する。On the other hand, a few minutes to an hour is sufficient for the moisture absorbing body (fl) to become low in moisture content due to moisture dissipation due to the energization of the heating element (2) and to be activated, and if the moisture content falls below a predetermined moisture content, heating is continued. Since there is no need to do so, the power supply is stopped as described above.
続いて上記のような通電停止の状態で吸湿を続けると室
内の湿気は低下するものの吸湿体(1)の含水率は徐々

設定しておき、設定時間が経過した処で再度発熱体(2
)への通電を開始する。Subsequently, if moisture absorption continues in the above-described state in which the electricity is not supplied, the moisture content in the moisture absorbing body (1) gradually increases, although the indoor humidity decreases. Therefore, the time required for the moisture content of the moisture absorbing body (1) to reach a predetermined value is set in advance using a timer (4), and when the set time has elapsed, the heating element (2) is reused.
) starts energizing.
以下、これを繰り返し、効果的な連続放湿を行う。Thereafter, repeat this to achieve effective continuous moisture release.

点もある。As described above, the present invention is characterized in that a heating element that does not hinder moisture release is attached to one side of a hygroscopic body in which a hygroscopic filler is internally retained in a porous body having continuous micro-voids, and a heating element that does not hinder moisture release is attached to the porous body. A temperature sensor is provided, and a timer is connected to the heating element, which stops energizing the heating element when the temperature sensor detects that a predetermined temperature has been reached, and causes the heating element to be energized again after a predetermined period of time has elapsed after the energization was stopped. Therefore, the temperature of the hygroscopic body is detected by a temperature sensor, and unlike conventional methods, it is not affected by ions caused by electrolysis of the hygroscopic filler, and has the advantage of less variation in detection. Since the device is a temperature sensor, it has the advantage of being simple and inexpensive, compact, and less likely to break down. Furthermore, no electricity is consumed while the timer is operating, and if the humidity in the room is relatively low, even if the heating element is turned on, it quickly reaches the specified temperature and turns off, so less electricity is required. There is also an advantage.
