Abstract

PURPOSE: A fire prevention device using a dual mode sensor for a gas stovetop is provided to sound an alert message or an alarm when a user moves away from the stovetop when the gas is turned on. CONSTITUTION: When infrared ray and smoke detecting sensors(105, 106) detects that a gas stovetop is in use or overheated, the sensors turns off a gas valve and transmits the state to a user. An alarm device/receiver(103) is installed near a door for receiving a signal that the gas stovetop is in use. A door opening and closing sensor(104) generates an electric signal according to an opened or closed door state of opening or closing and transmits the signal to an alarm device so that the alarm device generates an alarm or a voice message.

Description

Fire protection device using dual sensor {Safe Device for Gas Cook Top Using Dual Sensing System}

Gas Sensor, Magnetic Lead Switch, Flame Detection Sensor

When using gas heaters, gas is one of the most commonly used fuels with high calories, easy to use. However, gas is very dangerous because if it is mixed with air at a certain ratio, it will burn or explode rapidly if ignited. Gas accidents are mostly caused by careless handling of people, followed by product and facility failures. By places of use, accidents occur in restaurants and cafes and restaurants and factories, followed by apartments and general households.

The biggest feature in the combustion of combustible gases is that the liquid causes abnormal combustion (explosion) depending on the contact with oxygen compared to the solid. For normal reactions in which the combustion reaction continues normally while the gas is combusted in the burner or the gas supply rate, temperature, etc., such as vapor level combustion such as alcohol, etc., the mixture of combustible gas and air (or oxygen) If it is within the explosive limit in advance, there is no limit to the oxygen supply rate, so as long as flammables exist, the combustion temperature and rate of combustion continue to rise, and the gas causing combustion causes rapid thermal expansion due to high temperatures. There is a strong pressure. The most influential factors in gas safety accidents are the most frequent cases where the temperature of kitchen containers rises and leads to a fire when food is warmed around the user's side.

Therefore, there is a device that directly blocks the fire that prevents a fire by automatically closing the valve when a certain time is input by attaching a timer to the gas valve.

However, it is known that the effect is not good because of the inconvenience of turning each time by hand and lack of temperature recognition or double safety device.

The present invention is an alarm device that informs the state of gas use when moving from the gas use place.

Conventional gas alarms are predominantly gas leak alarms that detect gas leakage when not in use. The gas sensor detects LPG, LNG and city gas, making it possible to create a gas leak alarm that can be adjusted according to the concentration in the air. Such a gas leak alarm device does not prevent the risk of moving if the user forgets to stop using the gas when moving from the gas device to another place during the gas use.

Referring to the configuration of the conventional conventional gas leakage alarm device briefly described first, as shown in Figure 4, the built-in gas sensor is configured to sound an alarm when gas is detected.

Such a conventional gas leak alarm device detects a leak of a gas and cannot play a role when moving from a gas device during use of a gas.

Especially for housewives who forget to use gas and move from gas device, gas leak alarm device does not help, so there are many big and small accidents.

The present invention complements the function of the conventional gas leak alarm device as described above to forget that the gas is in use to determine the presence of the person with the declination sensor to prevent the movement from the gas device, if the person is not near for a long time Automatically closes the valve and doubles the smoke sensor to cope with the fire thoroughly to obtain psychological stability of the user.

It also provides a device that automatically informs the state of the gas device when the door is opened or closed using wired or wireless.

Alarms or alarms should be generated when moving from gas equipment while gas is in use.

Infrared sensor or smoke sensor detects gas in use and adjusts solenoid gas valve and sends signal to alarm device installed near the door by wire or wireless and generates alarm message when door is opened or closed. .

It prevents gas accidents by forgetting that gas is being used and preventing movement from the gas system.

1 is a perspective view of the gas range of the present invention and a perspective view near the door from the house,
Figure 2 is a perspective view of the device and the wireless transmission unit and the door receiving unit / alarm device and the door opening and closing sensor to confirm the use of the gas device of the present invention,
3 is an enlarged perspective view of a main part of FIG. 2;
4 is a perspective view of a conventional gas leak alarm device,

The present invention for achieving the above object is a sensor or device that can distinguish whether the gas is in use or non-use in the gas device, the transmitter and the receiver for transmitting the wireless or wired to the door and the receiver operates only when the door is opened and closed As a device configured to inform that the gas is being used as a voice recording message or an alarm, it will be made as described with reference to the accompanying drawings, the configuration, operation and function of the present invention.

1 is a perspective view of a gas stove 102 commonly used in the present invention and a perspective view of the vicinity of the door 101 in the house, and FIG. 2 is a device 105 for confirming the use of the gas device of the present invention. 106 is a perspective view of the wireless transmitter 106, the door receiver / alarm device 103, and the door open / close sensor 104, and an infrared sensor 105 installed at the gas control knob of the gas stove and smoke sensor 105 such as smoke detection. The gas control knob transmits wires or wirelessly that the gas is in use, or when the smoke sensor 106 installed around the gas flame indicates that the kitchen container is overheating, it automatically shuts off the solenoid bell. In addition, it transmits by wire or wireless, and when the receiving part of the door detects it and opens the door, a sensor such as a magnetic reed switch installed in the door or a human body sensor outside the door operates to emit an alarm or warning message.

When the gas use alarm device is configured as described above, the danger caused when moving from the gas device during gas use is prevented, so that an overheating or gas leakage accident due to the excessive use of the gas device can be prevented in advance. In addition, if you forget that you are using gas and move to a distant place, you can prevent the worry of whether you are using gas or not by reducing the time waste of returning the gas device.
