Abstract

PROBLEM TO BE SOLVED: To prevent a fire by an oil or an electric system from spreading by a method wherein a flame sensor senses a flame, and the spreading of the flame is judged in a specified period of time, the plug of a water with alkali salt tank is opened, and the water with alkali salt is discharged. SOLUTION: A flame sensor 3 detects an ultraviolet ray which is emitted from a flame, and transmits a detection signal to a control unit 4. By the input of this signal, a signal operation part 42 of the control unit 4 operates a timer 43, and waits the input of a signal for the passing of a specified period of time from the timer 43. When the input of this timer signal is received, a signal receiving part 41 judges whether the input of the flame sensing signal of the flame sensor 3 exists or not again. When there is the input, whether the flame becomes stronger or not is judged, and if the flame becomes stronger, a plug opening indication is output to a plug control part 4, and the plug of a water with alkali salt tank is opened, and the water with alkali salt is discharged. By this method, this fire preventive system can cope with a fire by an oil or an electric system, etc. Also, by judging whether the flame becomes stronger within a specified period of time, a wrong operation can be prevented from generating.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a house disaster prevention system, and more particularly to a house disaster prevention system capable of effectively preventing a fire from spreading from an oil stove or the like.

[0002]

2. Description of the Related Art Building fires have been declining in recent years due to the strengthening of the Fire Service Law and the Building Standards Law, but the damage caused by house fires has not stopped. House fires account for about 60% of building fires annually, and about 90% of all deaths from fires. Looking at the deaths from house fires by age, 65
Older people are more likely to die, and younger children are under 5 years old. In addition, the cause of death from home fires is most likely to be delayed, with the sick and disabled, followed by the elderly and infants.

[0003] Usually, a general fire extinguisher is installed in a house, and the weight of the main body is 5.5 kg to 7.0 kg.
Because of its heavy weight, the sick / disabled, elderly and infants could not use it, and could not perform the initial fire extinguishing, resulting in delayed escape.

[0004] Therefore, current fire protection equipment for houses is often installed simply as a fire protection equipment for buildings, and is operated by a sensor and a bell or buzzer sounds, or water or fire extinguisher is used. There is a method of releasing the agent. Commonly used sensors include differential spots that operate due to rapid temperature changes due to fire, constant temperature spots that operate when the local ambient temperature rises above a certain temperature, and constant ambient air. There are three types of smoke detectors that operate when they contain smoke above the concentration.

Hereinafter, a conventional house disaster prevention system using a conventional sensor will be specifically described. Conventional home disaster prevention systems use sensors that sense smoke or heat as fire sensors, and combine these sensors with sprinklers.When a sensor detects a fire, the associated sprinklers are activated to spray water into the room. To prevent the spread of fire.

As a specific system, there has been a system in which a tank filled with water is provided in the attic, a fire is detected by heat, and water in the tank is sprinkled to prevent the fire from spreading.

As another specific system, water sprinkled from a sprinkler is supplied from a water supply pipe, and when a fire is sensed by heat, water from the water supply pipe is sprinkled from the sprinkler to generate a fire. Some were to prevent the spread of fire.

Further, although not as large as a fire prevention system, it is a small fire extinguisher type that can be attached to a wall near a stove such as a kitchen, and senses heat to enhance liquid (fire extinguishing liquid).
Some release

In recent years, a flame sensor for detecting the flame by detecting ultraviolet rays emitted from the flame has been studied, and experiments are being conducted for practical use. The outline of the sensor technology related to disaster prevention is described in “Sensor Application Technology Handbook” published by the Industrial Resource Center on April 20, 1989, edited by Sensor Application Technology Handbook, pages 245 to 246.

[0010]

However, in the above-described conventional house disaster prevention system, a smoke or heat sensor is used as a fire sensor. However, a sensing criterion (threshold) is used to prevent malfunction and water spray. Value) is set high, and especially in the case of old wooden houses, since the fire turns around quickly, even if the sprinkler operates after being detected by such a sensor, there is a problem that it is not enough to extinguish the fire. there were.

In addition, the conventional house disaster prevention system in which the sprinkler operates requires the construction of a pipe from a water pipe, so that the cost is high and the installation is difficult in an existing building. Was.

Further, in the conventional house disaster prevention system, since water is sprinkled using water, there is a problem that it can cope with a normal fire but cannot cope with oil and electric system fires.

Furthermore, in a small fire extinguisher that senses heat and discharges a strengthening liquid, the amount of the strengthening liquid is small, so that the fire extinguishing time is short and the fire extinguishing distance is short. However, in this model as well, the heat sensing temperature is set higher to prevent malfunctions, so that even if this model is arranged in a plurality of rooms, it cannot be used for a house.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a house disaster prevention system capable of effectively preventing a fire from spreading by an oil or electric system other than a normal fire.
