Abstract

PURPOSE:To provide an apparatus which detects a flame to extinguish automatically when oil or the like in a pan catches a fire on a gas stove or the like. CONSTITUTION:A partition screen 6 is formed in a cylinder which is slightly larger than the shape of the outer circumference of a pot on a gas stove 2 and long just to let the lower end thereof reach the gas stove 2. An extinguishing unit holding the partition screen and an extinguishing agent jetting cylinder 5 into a housing is mounted right on the gas stove 2 and made to communicate with a flame detection sensor 4. The partition screen 6 hangs down by a detection output from the flame detection sensor 4 to wrap a flame rising from the gas stove while an extinguishing agent is jetted from the extinguishing agent jetting cylinder 5 to extinguish the fire.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically extinguishing a fire when oil is burned in a pan while cooking is cooked by a cooking machine such as a gas stove or a gas table. is there.

[0002]

2. Description of the Related Art At home, when frying tempura, fried food, etc. on a gas stove, many people leave the gas stove on the way because of telephone calls and visitors. In such a case, most people do not turn off the gas, so the oil in the pot may overheat before the person returns to the gas stove, which may cause the fire to start burning. .. Similarly, in recent years, when oil is put on fire in an attempt to mix a used oil with a hardening agent, there is an increasing number of accidents in which the fire is transferred to and burned. When the fire moves into the pan with a gas stove and the oil burns up, it is recommended to wet a large cloth such as sheets and put it on the pan to extinguish the fire.

[0003]

The fire extinguishing method using a cloth as described above extinguishes the fire by cutting off the supply of oxygen to the oil, and is effective as a method for extinguishing the oil fire.
However, in reality, when the oil in the pot burns up with a gas stove, the flame rises to a height of several hundred mm or more,
Since there is a high risk of burning onto walls and ceilings, even if the kitchen is equipped with a prescribed fire extinguishing cloth, it is extremely difficult to take it out and wet it in such a case without any upset. However, it is extremely difficult to cover a rising pot with a cloth. Moreover, there are usually two or more craters on a gas stove or a gas table, and in addition to that pot, a boiling pot is hung, and tableware and other cooking utensils are placed around it. Therefore, it is almost impossible to cover the burnt oil pan with a cloth to shut off the oxygen supply to the oil. An object of the present invention is to provide a device for automatically detecting a fire when oil or the like in a pan burns by a gas stove or the like and automatically extinguishing the fire.

[0004]

Means for Solving the Problems The present invention provides a partition film formed in a tubular shape having a length slightly larger than the outer peripheral shape of a pot to be hung on a gas stove and having a lower end reaching the gas stove. Attach a fire extinguisher unit containing a fire extinguishant jet cylinder in the housing directly above the gas stove, contact this with the flame detection sensor, and use the detection output from the flame detection sensor to hang down the partition film The above-described object is achieved by surrounding the flame rising from the above and extinguishing the fire by injecting the extinguishant from the extinguishant jet cylinder. An embodiment in which a mechanism for actuating the fire extinguishing unit by manual operation is also used in combination with the flame detection sensor can be used.

[0005]

The present invention, when the oil etc. in the pan burns with a gas stove etc., hangs down the partition film formed by using a non-combustible or flame-retardant cloth material or a mesh material to make a flame. Encircling eliminates the risk of fire burning to kitchen walls and elsewhere. Further, as a result, the extinguishant sprayed from the extinguishant spray cylinder is prevented from being scattered or blown away by the flame, and the extinguishant is filled in the partition film, so that the effect is surely exhibited.

EXAMPLE A fire extinguisher according to the present invention will be specifically described below based on an example applied to a gas stove. FIG. 1 shows a state in which a fire extinguisher is attached at a predetermined position above a gas stove. In the figure, reference numeral 1 is a cooktop, 2 is a gas stove,
3 is a fire extinguishing unit, and 4 is a flame detection sensor. Although not shown, the gas stove 2 is equipped with a fire extinguishing mechanism that is almost the same as an empty heating prevention mechanism, and when the detection output from the flame detection sensor 4 is received, the gas ejection is automatically stopped. Other than that, it is the same as a normal gas stove of this type, with two or four craters 21 formed, each with a tempura pot or other pot for cooking. , You can boil multiple dishes at the same time. The fire extinguishing unit 3 is a cylinder 5 for extinguishing extinguishant.
It is composed of a partition film 6 and a partition film 6, and is adapted to be used just above the gas stove 2. The extinguishant jet cylinder 5 is attached to the housing of the fire extinguishing unit 3 with the extinguishant jet nozzle 51 facing the gas stove 2, and ejects the extinguishant toward the origin of the gas stove 2. ing. The partition film 6 is formed in a tubular shape slightly larger than the outer peripheral shape of a pot or the like to be hung on the gas stove 2,
One end thereof is attached to the housing directly or by a suspending cord 61 having an appropriate length. This partition film 6
Is made of non-combustible or flame-retardant cloth or mesh material, and the lower end of the gas stove 2 when hanging from the housing
The length of the fire extinguishing unit 3 is normally formed by being folded and locked in the housing of the fire extinguishing unit 3. Then, when the lock is released, the flame hanging from the housing and rising from the gas stove 2 is deflected to eliminate the risk of the fire burning to the wall of the kitchen or the like, and the fire extinguishing agent jet cylinder 5 sprays the fire. It is designed to prevent the extinguishing agent from scattering and to exert its effect reliably. The flame detection sensor 4 detects when the flame rises above a certain level from the pot hung on the gas stove 2, and is connected to the gas stove 2 and the fire extinguishing unit 3. Then, the detection output is transmitted to the gas stove 2 to tighten the gas cock, and at the same time, this output is transmitted to the fire extinguishing unit 3 to operate it. In the embodiment shown in the drawing, the fire extinguishing unit 3 has a double-sided door with a bottom surface of the housing.
The jet nozzle 51 of the extinguishant jet cylinder 5 is closed by this door 31, and when the door 31 is opened, the jet nozzle 51 is opened to eject the extinguishant. The partition film 6 is also supported by the door 31, and when the door 31 is opened, it hangs down from the housing. And the double door 31 of this housing
A lock mechanism (not shown) is connected to the flame detection sensor 4, and when the detection output is transmitted from the detection sensor 4, the lock is released and the door 31 is opened.

INDUSTRIAL APPLICABILITY As described in detail above, the present invention is a partition formed in a tubular shape having a length slightly larger than the outer peripheral shape of a pot to be hung on a gas stove and having a lower end reaching the gas stove. A fire extinguishing unit containing a membrane and a cylinder for ejecting extinguishant is installed directly above the gas stove, and when the oil etc. in the pan burns on the gas stove, the partition membrane hangs down to create a flame. The fire extinguishes the walls of the kitchen and other parts because the partition film is made of non-combustible or flame-retardant cloth material or mesh material. The risk of migration is eliminated, and since it is possible to carry out fire extinguishing work with peace of mind, it is possible to prevent the occurrence of secondary disasters. In addition, since the fire is extinguished by the fire extinguishing agent jet cylinder due to the flame being surrounded by the partition film, the fire extinguishing effect is surely exhibited because the fire extinguishing agent is filled in the partition film without being blown away by the flame. Of.
