あった。Conventional technology Generally, in gas combustion appliances that use a switch whose contacts are closed only during operation, when the switch is operated once and the contacts are closed, combustion starts, and then the switch is turned on again. When the contact is closed again, combustion is stopped. Therefore, in the unlikely event that the switch malfunctions due to short circuit, it is impossible to start or stop combustion.
発明が解決しようとする問題点
従来のような構成であれば、スイッチがショートした場
合に、勝手に器具が燃焼を始めてしまうばかりでなく、
使用者が燃焼を停止させるべくスイッチを操作しても、
燃焼が停止せず、非常に不安全であった。Problems that the invention aims to solve With the conventional configuration, if the switch short-circuits, the appliance will not only start burning by itself, but also
Even if the user operates the switch to stop combustion,
The combustion did not stop, making it extremely unsafe.
本発明は、上記問題点を解決するために、あらかじめ設
定された時間以上スイッチの「閉」状態が続いた場合に
は、燃焼を停止させて、スイッチのショートによる器具
の暴走を防止する燃焼安全装置を提供するものである。In order to solve the above problems, the present invention has developed a combustion safety system that stops combustion if the switch remains closed for a preset period of time to prevent the appliance from running out of control due to a short circuit in the switch. It provides equipment.
問題点を解決するだめの手段
上記問題点を解決するために、本発明の燃焼安全装置は
、スイッチの接点の「閉」状態の時間を計測し、一定時
間以上「閉」状態が続いた時には、電磁弁を閉じる制御
装置を備えた構成である。Means for Solving the Problems In order to solve the above problems, the combustion safety device of the present invention measures the time that the contacts of the switch are in the "closed" state, and when the "closed" state continues for a certain period of time or more, , the configuration includes a control device that closes the solenoid valve.
作 用
本発明は、上記した構成により、スイッチのショートの
ように常時接点が「閉」となるような異常を検出し、電
磁弁を閉じて、燃焼を停止させることができる。Function: With the above-described configuration, the present invention can detect an abnormality such as a short circuit in a switch where a contact is always "closed", close the solenoid valve, and stop combustion.
実施例
以下、本発明の一実施例について図面を用いて説明する
。EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

スイッチ４のショートを判定するショート故障検出手段
６を備えている。The figure shows a configuration diagram of a combustion safety device in an embodiment of the present invention, in which 1 is a burner, 2 is a solenoid valve that opens and closes the gas passage to burner 1, 3 is an ignition device, and 4 is a contact that is closed only during operation. ”
Bush type operation switch, 5 is operation switch 4
The signal goes up and controls the solenoid valve 2 and ignition device 3 to turn on the burner 1.
It is a control device that controls ignition and extinguishing of the
The apparatus is equipped with a short-circuit failure detection means 6 that measures the time during which the switch contact is "closed" and determines that the operation switch 4 is short-circuited when the "closed" state continues for a preset time or more.
以上のように構成された燃焼安全装置について以下、そ
の動作を説明する。The operation of the combustion safety device configured as described above will be explained below.
使用者が、燃焼器具を使用すべく運転スイッチ４を操作
すると、スイッチ検出手段７が、その運転信号を検出し

検出手段６は、運転スイッチ４の「閉」時間を計測し始
める。その後、使用者が運転スイッチ４よ９手を放し、
運転スイッチ４が「開」になると、スイッチ検出手段７
は、ショート故障検出手段６への信号を切る。When the user operates the operation switch 4 to use the combustion appliance, the switch detection means 7 detects the operation signal and transmits the signal to the solenoid valve drive means 8 and the ignition device drive means 9, and the solenoid valve 2 Then, the ignition device 3 operates to ignite the burner 1. At this time, the switch detection means 7 also transmits a signal to the short-circuit failure detection means 6, and the short-circuit failure detection means 6 starts measuring the "closed" time of the operation switch 4. After that, the user releases the operation switch 4 and 9,
When the operation switch 4 is opened, the switch detection means 7
cuts off the signal to the short-circuit failure detection means 6.
ここで万一、スイッチがショート故障していれば、スイ

切れず、ショート故障検出手段６は、あらかじめ定めら
れた時間が経過すると同時に、電磁弁駆動手段８へ電磁
弁２のを閉じる信号を伝え、電磁弁２が閉じて燃焼が停
止する。If the switch has a short-circuit failure, the signal from the switch detection means 7 to the short-circuit failure detection means 6 will not be cut off, and the short-circuit failure detection means 6 will detect the solenoid valve as soon as a predetermined time elapses. A signal for closing the solenoid valve 2 is transmitted to the driving means 8, and the solenoid valve 2 is closed and combustion is stopped.
一方、運転スイッチ４が正常であれば、使用者が運転ス
イッチ４よシ手を放すことによシ、ショート故障検出手
段６への信号が切れて、ショート故障を検出することな
く、燃焼を続け、使用者が器具を停止すべく再度、運転
スイッチ４を操作すると、前述と同様、スイッチ検出手
段７、電磁弁駆動手段８により電磁弁２が閉じて燃焼が
停止する。On the other hand, if the operation switch 4 is normal, when the user releases the operation switch 4, the signal to the short-circuit failure detection means 6 is cut off, and combustion continues without detecting a short-circuit failure. When the user operates the operation switch 4 again to stop the appliance, the switch detection means 7 and the electromagnetic valve driving means 8 close the electromagnetic valve 2 and stop combustion, as described above.
以上のように、本実施例によれば、運転スイッチのショ

スイッチ故障による燃焼器具の誤動作を防止することが
できる。As described above, according to this embodiment, if the contact is always "closed" as in the case of a short circuit in the operation switch, the short circuit failure detection means 6 operates to stop combustion.
Malfunctions of combustion appliances due to switch failure can be prevented.
