本考案はガス機器と換気扇を連動する換気扇連動装置に
係り、電気配線を単相３線式で行う場合に入力電源は２
線、出力線は１線で屋内配線を行い、設置工事を容易に
することを目的とする。[Detailed description of the invention] This invention relates to a ventilation fan interlocking device that links gas appliances and ventilation fans, and when electrical wiring is done in a single-phase three-wire system, the input power is 2
The purpose is to perform indoor wiring with a single line and output line to facilitate installation work.
従来の換気扇連動装置は第１図に示すように、入力電源

No current flows through the gate of the thyristor 108, and the alarm buzzer 109 does not sound.
また換気扇のスイッチ１１０が切れているときは電流が
流れないのでトランジスタ１０７は動作せず、警報ブザ
−１０９が鳴る。Further, when the ventilation fan switch 110 is turned off, no current flows, so the transistor 107 does not operate and the alarm buzzer 109 sounds.
又第２図のように単相３線式で配線する場合には電流検
出の逆並列ダイオード１０６に電流が流れないので換気
扇は運転していても警報ブザ−１０９が鳴るという欠点
を有していた。Also, when wiring is done in a single-phase three-wire system as shown in Figure 2, no current flows through the anti-parallel diode 106 for current detection, so there is a drawback that the alarm buzzer 109 sounds even if the ventilation fan is running. Ta.
本考案は上記従来の欠点を解消するもので、以下にその
実施例を第３〜４図にもとづいて説明する。The present invention solves the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to FIGS. 3 and 4.

1 and the cathode side through a resistor 17.
２０は本考案の換気扇連動装置である。20 is a ventilation fan interlocking device of the present invention.
上記構成において、ガス機器の信号接点３がガス機器の
使用時に動作し、トランスリレー２の二次側を短絡し、
トランスリレー２が動作し、接点４が閉じ、逆並列ダイ
オード７を通して換気扇スイッチ６側に電流が流れよう
とする。In the above configuration, the signal contact 3 of the gas appliance operates when the gas appliance is used, short-circuiting the secondary side of the transformer relay 2,
The transformer relay 2 operates, the contact 4 closes, and current attempts to flow through the anti-parallel diode 7 to the ventilation fan switch 6 side.
この時スイッチ６が入っていると換気扇５は運転し、電
流が流れるので逆並列ダイオードの両端に電圧降下分の
電圧が発生し、トランジスタ８のベースに’Ｉ［Ｅが流
れトランジスタ８は動作する。At this time, when the switch 6 is on, the ventilation fan 5 operates and current flows, so a voltage equivalent to the voltage drop is generated across the anti-parallel diode, and 'I[E flows to the base of the transistor 8, causing the transistor 8 to operate. .
この場合換気扇の電流は電源１の非接地側から接点４、
逆並列ダイオード７、換気扇のスイッチ６、換気扇５、
接地線を通って電源１に流れるのである。In this case, the ventilation fan current flows from the non-grounded side of power supply 1 to contact 4,
Anti-parallel diode 7, ventilation fan switch 6, ventilation fan 5,
It flows to the power supply 1 through the ground wire.
トランジスタ８が動作するとトランジスタ１１のベース
に電流が流れトランジスタ１１が動作し、サイリスタ１
８のゲートには電流が流れず、サイリスタ１８は動作せ
ず警報ブザ−１９は鳴らない。When transistor 8 operates, current flows to the base of transistor 11, transistor 11 operates, and thyristor 1
No current flows through the gate 8, the thyristor 18 does not operate, and the alarm buzzer 19 does not sound.
反対にガス機器使用時に換気扇のスイッチ６が切れてい
ると、換気扇に電流が流れないので、トランジスタ８は
動作せず、同じくトランジスタ１１も動作せず、整流ダ
イオード１４、抵抗１５゜１６．１７の回路に電流が流
れ、サイリスタ１８のゲートにも電流が流れ、警報ブザ
−１９は鳴る。On the other hand, if the ventilation fan switch 6 is turned off when using a gas appliance, no current flows to the ventilation fan, so the transistor 8 does not operate, and the transistor 11 also does not operate, causing the rectifier diode 14 and resistor 15° 16.17 Current flows through the circuit, current also flows through the gate of the thyristor 18, and the alarm buzzer 19 sounds.
このように本考案によれば、換気扇連動装置の非接地側
の入力と出力間にトランスリレーの接点と電流検出の逆
