Abstract

PROBLEM TO BE SOLVED: To provide a gas control device mounted between a gas master plug in a room and a gas equipment for use in controlling a gas flow in reference to signals of various kinds of sensors or a timer for safe use of gas. SOLUTION: This gas control device 9 is comprised of an input terminal 8 for various kinds of sensor signals, a plug 2 for a ventilation fan, a terminal 3 for a ventilation fan, a human body infrared ray sensor 4, a power supply cord 5, a gas stopping switch 6, a gas recovering switch 7, an abnormal; state display lamp 10 for inputting various, a gas output display lamp 11, a timer adjusting knob 12, a venation fan switch 13, a human body sensor display lamp 14, a time-up display lamp 15 and a supply lamp 16. A gas electromagnetic valve 1 is connected so as to control gas.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a device for safe use of a gas, which is installed between a main valve of a gas chamber and a gas appliance and controls the flow of the gas by signals of various sensors and timers. .

[0002]

2. Description of the Related Art Conventionally, regarding the safety of gas, whether a sound is emitted by a gas leak alarm or a request is made for the output of the alarm to send a signal to the microcomputer meter which is the supplier of the building to shut off the gas. It was a system with the function of preventing the heating of a high-grade gas stove and extinguishing prevention. The micom meter has the functions of detecting earthquakes and checking for abnormal gas emissions, but of course it is necessary to install a micom meter.

[0003]

[Problems to be solved by the invention] It can be easily installed in a room simply by connecting a gas hose, and the signal of various sensors and the monitoring function by a timer prevent the danger of gas in daily life and at the time of disaster.

[0004]

An electric signal is passed through the gas solenoid valve 1 to control the gas flow. Since the gas solenoid valve 1 is closed when electricity does not flow from the device 9, the gas is stopped at the time of a power failure and the gas is shut off even when the power is restored until the reset switch is pushed by the power reset circuit. If the outlet of the ventilation fan is plugged into the outlet 2 of the ventilation fan, or the two cords from the ventilation fan terminal 3 are connected to the switch of the ventilation fan, the ventilation fan is automatically turned if there is a signal of the gas leak sensor. Or turn with a manual switch. Both use a zero-cross electronic circuit or a closed switch to turn the ventilation fan without worrying about ignition. The human infrared sensor 4 and timer circuit stop the gas when it is not near the gas appliance for a certain period of time. Gas stop switch 6, return switch 7
Can also directly control the gas flow. Signals 8 from various sensors can also be connected to control the gas flow. The signal from this sensor uses gas leak, and smoke uses the signal from both ends of each buzzer. The cooking temperature and the room temperature may be signals that turn on or off the output of the open collector at temperatures above the set values. The seismic sensor uses contact output.

[0005]

When the power is turned on, the gas is initially stopped by the power reset circuit. The return switch 7 allows the gas to flow. Since the internal timer circuit is reset by the output of the human infrared sensor 4, the timer starts counting after leaving the place. A hold circuit is provided for each signal, and the gas remains stopped until the return switch 7 is pressed. Ventilation fan switch 13 allows manual ventilation. Ventilate automatically if there is a gas leak or smoke sensor signal. When using the outlet 2 for the ventilation fan, switch on the ventilation fan main body. When using the ventilating fan terminal 3, the switch of the ventilating fan main body is turned off, but for safety in both cases, the ventilating fan switch 13 is always used without using the switch of the ventilating fan main body.

[0006]

[Example] A gas controller 9 is installed near a gas appliance,
Insert the power cord 5 into the outlet and connect the gas hose of the solenoid valve to the main plug and the gas appliance, respectively. Connect the solenoid valve cord. Connect the ventilation fan cord and various sensor cords as necessary. Gas is initially stopped by power reset. Gas can be flowed with the return switch. Since the internal timer circuit is reset by the output of the human infrared sensor 4, the timer starts counting after leaving the place. A hold circuit is provided for each signal so that the gas remains stopped until the return switch is pressed.

[0007]

The gas hose can be easily connected, and various sensors such as gas leak, smoke, cooking temperature, room temperature, earthquake, etc. can be connected if necessary, and dangerous gas can be used with confidence.
