JPS58145811A - Apparatus for extinguishing oilstove without giving off smell - Google Patents

Abstract

PURPOSE:To prevent an offensive smell from being given off when an oilstove is extinguished, by extinguishing the oilstove with the fuel sucking section and the fuel out of contact with each other. CONSTITUTION:The tip of a cylinder 6 can be swung by rotating a handle 7, and when the tip is lowered, it is submerged in a fuel tank 8, while when the tip is raised, it moves from the fuel tank 8 to be displaced to the position 6'. Following the swing of the cylinder 6, the tip of the sucking wick 4 is swung so that the tip can be brought in contact or out of contact with the petroleum in the fuel tank 8. In other words, during the contact of the tip of the sucking wick 4 with the petroleum in the fuel tank, the supply of the fuel to the wick 3 continues, while when they are out of contact, the supply of the fuel to the wick 3 is stopped to extinguish the oilstove. Thus as the supply of air is enough to perform complete combustion while the petroleum remaining in the wick 3 is burning, an offensive smell can be prevented from being given off.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a fire extinguishing device that eliminates bad odors generated when extinguishing a kerosene stove. A major drawback of kerosene stoves is the foul odor emitted when extinguishing a fire, and in extreme cases can cause headaches and nausea for some people. Although it has been studied for many years,
No effective method has been developed. Rather, the current situation is that users have to be patient by opening windows and dispersing indoor odors to the outside. This odor contains carbon monoxide and irritating toxic substances, is not physiologically desirable, and must be prevented from occurring. The cause of this is due to the incomplete combustion of petroleum, which occurs because the conventional fire extinguishing method uses an insufficient supply of air to extinguish the fire. That is, the fire is extinguished by lowering the upper end of the burning wick into the gap between the core guide tube (1) and the core outer tube (2), thereby inevitably making the supply of air insufficient. Therefore, petroleum gas naturally undergoes incomplete combustion, which gives rise to foul odors.

The present invention is devised to naturally extinguish the fire by cutting off oil suction while maintaining complete combustion without lowering the position of the burning wick (3). That is, once the small amount of petroleum already contained in the wick (3) vaporizes and burns out, the fire will naturally extinguish, and since the combustion is complete, no bad odor will be generated. The details are explained below.

b) Figure 1 is a perspective view of the combustion tube. The drawing was drawn to clarify the positioning of the core guide tube portion in FIG. 2, so it is not particularly necessary for explaining the present invention.

(b) The core outer tube (2) is connected to the core (3), and as the core outer tube (2) moves up and down, the core (3) moves up and down the peripheral wall of the core guide tube.

(c) The lower part of the wick (3), that is, the part that directly contacts the fuel in the fuel tank and sucks up the fuel, is made of a suitable thickness.
Or, make it easy to bend into a thick band or string shape. Hereinafter, this part will be referred to as the suction wick (4) to distinguish it from the upper part of the wick (3), which is related to combustion.

2) The support plate (5) is a plate that surrounds the lower part of the core guide tube (1) vertically to prevent the wick from falling into the fuel tank from the middle and sucking up oil. This is a support plate for the suction core (4). This support plate (5)
The wick (4) is slightly sloped toward the distal end so that the oil that has been sucked up does not accumulate on the support plate (5).

...The suction wick (4) is stretched over the support plate (5),
Its end passes through the interior of the tube (6) into the fuel tank and comes into contact with the oil. That is, oil is sucked up only from this end of the wick (4).

(f) As the handle (7) rotates, the tip of the cylinder (6) sinks into its head, and when it comes up, it escapes from inside the fuel tank.
(Displaced to the position of φ. As the tube (6) moves up and down, the end of the suction wick (4) also moves up and down and comes into contact with and separates from the oil in the fuel tank. In other words, the end of the suction wick (4)
) is in contact with the oil in the fuel tank, fuel is supplied to the wick (3), and when the two are separated, the wick (3) is supplied with fuel.
3) The fuel supply is cut off and the fire is extinguished. Moreover, the core (3
) while the remaining oil burns out, air is supplied I.
Since the fuel is completely burned in a sufficient condition, no foul odor is generated. As described above, the present invention is characterized by a fire extinguishing method in which the fire is extinguished by cutting off contact between the suction wick (4) and the fuel.

The conventional method of extinguishing a fire by pulling down the wick (3) and insufficiently supplying air not only produces a bad odor, but also causes the wick (3) to
) because carbon adheres to the upper end and becomes charcoal-like.

A) Raising and lowering the core becomes difficult.

Tol　The heat dissipation net does not become red hot enough.

tel Battery-powered ignition makes it difficult to catch fire.

A foul odor will also be generated during combustion.

(el) Carbon not only adheres to the upper end of the wick (3), but also forms on other surfaces and inside the wick, which prevents the smooth vaporization of the fuel and reduces the calorific value of the fuel. It would also be a waste.

The above-mentioned 11 (bl dl) also arises from the same cause.

In the present invention, since a state of complete combustion is always maintained, carbon adhesion does not occur, and the wick remains soft and clean at all times, so the above-mentioned functional disorder does not occur.

In order to prove the fact that the method of the present invention does not generate any bad odor, the following experiment was conducted.

Using the conventional method of extinguishing a fire by pulling down the wick (3), if you relight it immediately after the fire has completely gone out, it will instantly ignite with a sound. This proves that petroleum gas is still being generated even after the fire has been extinguished, and this gas creates a foul odor that lingers inside the room.

When reignited using the method of the present invention, no changes occur and no re-ignition occurs at all. This means that the oil still contained in the wick (3) even after the suction wick (4) and the oil are no longer in contact with each other is proof that it has been completely burned, which is why no foul odor is generated. Moreover, in the case of the next ignition,
When the handle (7) is returned and the suction wick (4) comes into contact with the oil, the oil is immediately sucked up and the oil can be ignited as quickly as a sponge sucking up water in less than one minute. It returns to .

From the above, this method is practical and not inferior to conventional methods in terms of time.

Claims (1)

[Claims] This kerosene stove fire extinguishing system has a structure in which a suction part at the top of the wick draws up the fuel by directly contacting the fuel in the fuel tank of the kerosene stove, and extinguishes the fire by separating the contact with the fuel.
