Abstract

PURPOSE:To prevent nonburnt gas to be generated at the time of fire extinguishing from generating and to prevent foul odor from producing, by a method wherein a small hole for instantaneous fire extinguishing is provided on a wick holding cylinder and a damper which opens and closes the above small hole by interlocking with a rotation of a wick up-and-down knob is provided. CONSTITUTION:A combustion wick 3 is moved vertically inside a wick holding cylinder 1 by an operation of a wick up-and-down knob 4, and a system consisting of a movable damper 7, a speed reduction gear 5 and a rotary lever 6 and moves the damper 7 vertically by interlocking with a rotation of the knob 4 is provided inside the cylinder 1 When a fire is extinguished, that is, the knob 4 is applied for lowering a wick, the cylinder 1 is not cooled so suddenly too, as a small hole 2 is shut by the damper 7 and air is prevented from flowing into the cylinder 1. A flame, therefore, is not extinguished, which is made into a ball- like blue flame at the upper part of the cylinder 1 and evaporated gas is burnt completely. A foul odor, therefore, resulting from nonburnt gas is prevented from occurring.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combustor for preventing the foul odor that is likely to occur when extinguishing a fire, which is one of the drawbacks of oil combustors.

Currently, oil burners, especially portable oil stoves, are used in many households because the fuel cost is lower than gas stoves, but this portable oil stove almost completely solves the problem of odor during normal combustion. When the thing ignites,
When a fire is extinguished, incomplete combustion produces a bad odor, and although many efforts have been made to prevent this, it is still far from perfect.

In particular, the portable kerosene stoves with an upper and lower wick that have recently appeared on the market tend to have a small hole in the wall of the wick housing cylinder for instantaneous extinguishing. The reason why this small hole allows for instant extinguishing is that if the combustion wick is lowered in close contact with the wick-accommodating cylinder wall,
The space created as a result of the downward movement of the combustion wick temporarily suppresses the upward draft of the combustion cylinder, but due to the temperature difference between the inside and outside of the wick storage cylinder, there is negative pressure inside, so the combustion wick is forced into the small hole. When the tank is lowered, the small hole suddenly opens, and air is instantly blown into this negative pressure area through the small hole, diluting the vaporized oil gas and spreading the flame in the gap between the combustion cylinders to the combustion core. It does not spread and is extinguished instantly.

However, with this method, when the wick is lowered, a large amount of cold air is supplied from the small hole into the wick housing cylinder, so the wick housing cylinder is rapidly cooled and the vaporized petroleum gas remains incompletely combusted. On the contrary, it causes a bad odor.

As a method that partially improves these drawbacks, a method has been proposed in which an oxidation catalyst is placed on the combustor to catalytically burn the bad odor. However, this method has a problem in that not all of the bad odor passes through the catalyst, and it is difficult to completely prevent the bad odor during extinguishing.

The purpose of the present invention is to use a small hole in the wall of the wick housing cylinder for instantaneous extinguishing, but to close this instantaneous extinguishing hole during normal extinguishing, thereby preventing the occurrence of bad odors during normal extinguishing. The purpose of this project is to provide a combustor for oil and combustor.

Next, the oil combustor of the present invention will be explained based on examples. FIG. 1 is a sectional view showing an embodiment of the oil combustor of the present invention. In Fig. 8, numeral 1 denotes a wick housing cylinder, and a small hole 2 for instantaneous extinguishing is provided in the side wall of the cylinder. A combustion wick 3 is housed in the wick storage cylinder 1 in close contact with its side wall, and by moving the combustion wick 3 up and down with a wick up and down knob 4, its firepower is adjusted and the sensitivity is adjusted. The vibrator and the set are also configured such that the small hole 2 of the core housing cylinder 1 is located upward.

This core upper and lower knob 4 is connected to a rotary track 6 via a reduction gear 5.
is engaged, and due to the rotation of this rotary track 6, the
4'-7 is configured to be moved in the vertical direction.

During combustion, the combustion wick 3 and the wick housing tube 1 are in close contact with each other as shown in the figure, so that the inflow of air from the small holes 2 into the combustion section is largely cut off. When the automatic instantaneous extinguishing function is activated in such a situation, air can flow into the upper part of the combustion wick through the small hole 2, and this achieves instantaneous extinguishing of the flame, but at the same time generates a bad odor. cannot be avoided in principle.

On the other hand, as shown in FIG. 2, when normally extinguishing a fire, that is, when extinguishing a fire by operating the wick upper and lower knobs 4, as the wick upper and lower knobs 4 rotate, the combustion wick 3 is lowered and stored in the wick storage tube 1. As a result, the vaporization of the oil is suppressed and the flame quickly becomes smaller. By operating the lead upper and lower knobs 4, the lead storage cylinder 1 is
The damper 7 provided inside the core housing cylinder 1 is raised, the small hole 2 of the core housing cylinder 1 is closed, and air is prevented from flowing into the core housing cylinder 1, so that the core housing cylinder 1 may be rapidly cooled. do not have.

Therefore, the flame does not go out and turns into a small blue ball-shaped flame at the top of the wick housing cylinder 1, and the vaporized gas is completely burned. When the core storage cylinder is sufficiently cooled and vaporization stops, the core is finally digested.

Therefore, even if the oil is slightly vaporized from the combustion wick, the wick housing cylinder is kept at a high temperature, so the air supplied from the top completely burns it as a ball of blue flame.
The generation of bad odors due to unburned garro is prevented.

On the other hand, during the next combustion, when the wick up/down knob 4 is rotated in the opposite direction to move the combustion wick 3 upward, this rotation also moves the damper/mother 7 downward, so that it is closed by the damper 7. The small holes 2, which had been in the combustion chamber, are now opened and remain open during combustion. Therefore, if the seismic sensor is activated, the fire can be extinguished instantly.

As explained above, in the present invention, in an oil combustor in which a small hole for instantaneous extinguishing is provided in the wick housing cylinder,
A damper is installed that opens and closes the above-mentioned small hole in conjunction with the rotation of the top and bottom of the wick and the knob, so the simple structure prevents the generation of unburned gas that normally occurs when extinguishing a fire, and prevents oil combustion from producing a foul odor. It becomes possible to provide the equipment at low cost.
