上述の太陽電池を用いた床下換気装置によると、換気扇の電源として太陽電池および商用電源を用いているので、例えば夕立などが発生し太陽光が弱まった時でも商用電源により換気扇が駆動されるので、湿った空気が他の換気口から床下へ導入され、床下に湿気が充満すると言う問題点があった。 According to the underfloor ventilator using the above-described solar cell, since the solar cell and the commercial power supply are used as the power supply of the ventilation fan, the ventilation fan is driven by the commercial power supply even when, for example, showers occur and the sunlight is weakened. However, there is a problem that the moist air is introduced into the floor from another ventilation port, and the floor is filled with moisture.

この考案は、上述のような問題点を解決するためになされたもので、夕立等が発生しても、換気扇を停止させることができる床下換気装置を得ることを目的とする。 The present invention has been made to solve the above-described problems, and has as its object to obtain an underfloor ventilation device capable of stopping a ventilation fan even when a shower or the like occurs.

この考案に係る床下換気装置においては、商用電源により駆動される換気扇を開閉するスイッチ装置を備えた床下換気装置において、スイッチ装置は、太陽光を受光して発電する太陽電池セルと、この受光センサー部に流れる電流により作動される動作コイルと、この動作コイルにより開閉されるスイッチとを備えたものである。 In the underfloor ventilation device according to the present invention, in a underfloor ventilation device including a switch device for opening and closing a ventilation fan driven by a commercial power supply, the switch device includes a solar cell that receives sunlight and generates power, and a light receiving sensor for the solar cell. And a switch that is opened and closed by the operation coil.

また、太陽光を受光して発電する太陽電池セルと、光を受けて内部抵抗が変化する光導電セルとを並列に接続した受光センサー部と、この受光センサー部に流れる電流により作動される動作コイルと、この動作コイルにより開閉されるスイッチと、上記動作コイルおよび上記受光センサー部へ電力を供給する電圧変換器とを備えたものである。 Also, a light-receiving sensor unit in which a solar cell that receives sunlight and generates power, a photoconductive cell that changes its internal resistance in response to light, and a current flowing through the light-receiving sensor unit are operated. A coil, a switch that is opened and closed by the operating coil, and a voltage converter that supplies power to the operating coil and the light receiving sensor unit.

この考案の床下換気装置は、スイッチ装置として太陽電池セルと光導電セルとを並列に接続し、リレーを動作させ、換気扇をオン・オフさせるようにしたので、夕立等が発生した場合に換気扇を停止させることが出来、湿った空気が床下へ導入されないので、床下に湿気が充満しなくなる。 The underfloor ventilation device of the present invention connects a solar cell and a photoconductive cell in parallel as a switch device, operates a relay, and turns on / off a ventilation fan, so that when a shower or the like occurs, the ventilation fan is used. It can be shut down and no moist air is introduced under the floor, so there is no moisture under the floor.

FIG. 1 is an electric circuit diagram of the underfloor ventilation device according to the first embodiment of the present invention. In the figure, 1 is a commercial power supply, 2 is a voltage converter for converting the commercial power supply 1 to a DC power supply, 3 is a light receiving sensor unit, and a solar cell 4 for generating electricity by receiving direct sunlight and receiving light. Reference numeral 6 denotes a relay, which is configured by connecting photoconductive cells 5 having variable internal resistances in parallel. The relay 6 includes an electromagnet 7 having an operation coil 7a and a switch 8. The operation coil 7a and the light receiving sensor unit 3 are connected in series, and power is supplied from the voltage converter 2. Reference numeral 9 denotes a ventilation fan, which is driven by the commercial power supply 1 and turned on / off by a switch 8. Reference numeral 10 denotes a switch device, which includes a light receiving sensor unit and a relay 6.

次に、上述のように構成された床下換気装置の動作を説明する。
図１の接続状態で、夜間、雨天、曇りの状態では、太陽電池セル４は発電しない、光導電セル５の内部抵抗が高いため動作コイル７ａへは殆ど電流が流れないので、電磁石７は吸引されず、スイッチ８はオフ状態であり、換気扇９は停止している。
次に、太陽電池セル４および光導電セル５に太陽光が照射されると、同時に太陽電池セル４の表面に幅射熱が生じ発電し通電を開始し、光導電セル５が引き金となって一挙に動作コイル７ａに電流が流れ、電磁石７は吸引動作し、スイッチ８はオン状態になり、換気扇９が作動し床下の換気が促進される。Next, the operation of the underfloor ventilation device configured as described above will be described.
In the connection state of FIG. 1, in the nighttime, rainy weather, or cloudy state, the solar cell 4 does not generate power, and since the internal resistance of the photoconductive cell 5 is high, almost no current flows to the operation coil 7 a. However, the switch 8 is off and the ventilation fan 9 is stopped.
Next, when the solar cell 4 and the photoconductive cell 5 are irradiated with sunlight, a width radiant heat is generated on the surface of the solar cell 4 at the same time to generate electricity and start energizing, and the photoconductive cell 5 is triggered. A current flows through the operation coil 7a at a stroke, the electromagnet 7 performs an attraction operation, the switch 8 is turned on, the ventilation fan 9 operates, and ventilation under the floor is promoted.

次に、上記スイッチ８のオン状態から、夕立等緊急時、及び夕暮れ、雨天、厚い雲状態に向かう時の動作を説明する。
まず、スイッチ８のオン状態から夕立等緊急時では、太陽光の直射がなくなると共に太陽電池セル４の表面に輻射熱がなくなり、発電が止まり通電もしない。一方、光導電セル５においても周囲の光・照度も下がり光導電セル５の内部抵抗も高くなり通電を妨げるようになる。この時動作コイル７へ流れる電流は極度に減少し、電磁石７の吸引は開放され、スイッチ８はオフ状態となり、換気扇９は停止する。また、夕暮れ、雨天、夜間等も上記と同様、換気扇９は停止する。Next, an operation from the ON state of the switch 8 to an emergency such as a shower, or to a state of dusk, rain, or thick clouds will be described.
First, in an emergency such as a shower after the switch 8 is turned on, direct sunlight does not radiate and radiant heat disappears on the surface of the photovoltaic cell 4, power generation stops, and no electricity is supplied. On the other hand, in the photoconductive cell 5 as well, the surrounding light and illuminance are reduced, and the internal resistance of the photoconductive cell 5 is also increased, so that energization is prevented. At this time, the current flowing to the operating coil 7 is extremely reduced, the attraction of the electromagnet 7 is released, the switch 8 is turned off, and the ventilation fan 9 is stopped. Further, the ventilation fan 9 is stopped at dusk, rainy weather, nighttime, and the like in the same manner as described above.

上記のように構成された床下換気装置は、太陽光の直射を受けて、スイッチ装置１０のスイッチ８により換気扇９が開閉されるので、太陽光を照射している時間帯が最も大気が乾燥している時間帯であり、この時間帯の中で換気扇９を駆動させ、その時間帯以外は停止しする、全自動の床下換気装置である。 In the underfloor ventilation device configured as described above, the ventilation fan 9 is opened and closed by the switch 8 of the switch device 10 in response to direct sunlight, so that the atmosphere is dried most during the time of irradiation with sunlight. This is a fully-automatic underfloor ventilation device in which the ventilation fan 9 is driven during this time period and stopped during other times.
