Range hood with gas leakage sense and fire suppress function

The present invention relates to a range hood of a kitchen, and in particular, detects a gas leak in the kitchen, emits an alarm and voice sound, discharges the leaked gas, and detects a gas leak and suppresses the fire at an early stage after the automatic detection of a fire. It is about a range hood equipped.

In general, gas is an essential fuel for our residential life, and it has always been a source of fear for gas accidents, and the casualties caused by gas fires in places such as houses and apartments are increasing day by day. The installation of gas safety equipment and fire extinguishers is not only inconvenient to install them separately after the installation of kitchen sinks, gas appliances, range hoods, etc., but also by the manufacturers. Later, the installation was again inconvenient, such as re-installation, and after-sales service was also different.

In addition, the conventional range hood has only a simple function of releasing odors when cooking food. Accordingly, when gas leaks in a kitchen where gas and fire handling are frequently carried out, large and small gas explosions occur, causing property damage from fire and fatal casualties. There were also many problems that could cause.

In order to solve the above problems, the present invention is equipped with an automatic fire extinguisher in a gas leak detection automatic discharge system (patent registration No. 0254495) and a gas leak detection automatic discharge hood inside the chimney type range hood and interlocked with a controller and a gas circuit breaker. And a range hood having a gas leakage detection and fire suppression function integrated with a voice generator.

In order to achieve the above object, the present invention, the gas leakage detection discharge circuit unit for detecting when the gas leaks in the kitchen frequently handle gas and fire, alarm and voice sound for the leakage of gas detected through the gas leakage detection discharge circuit unit A voice generator that continuously emits a sound, a gas circuit breaker that cuts off an intermediate valve of gas under the control of a control unit for controlling gas supply at the same time as the alarm sound, and an ambient temperature of the gas range is increased due to overheating to detect heat. The fire extinguishing liquid is automatically sprayed through a nozzle installed sealedly connected to the injection nozzle body of the central portion of the chimney-type range hood portion, and an automatic fire extinguishing unit is installed to extinguish the fire initially.

The chimney range hood of the present invention is mounted on the range hood which is the only discharge system of the kitchen where gas and firearms are frequently handled to protect valuable property and life from gas explosion accidents or fires. It has a lot of space, so the gas leakage automatic detection alarm ejector and fire extinguisher are installed inside the hood so that the range hood is installed on the top of the gas range of the sink without any deformation.
