Abstract

PROBLEM TO BE SOLVED: To provide a method for shifting flaming to flowing in an incense stick, and an incense burner for generating perfumed smoke by shifting the flaming of the incense stick, automatically ignited, to the glowing. SOLUTION: A solid body close to a flame has an effect of cooling the flame, so that the solid body in a certain distance from the flame extinguishes the flame, since the flame can not be maintained due to the flame cooling. While, the solid body has an effect of cooling a glowing portion little enough to be ignored. Which extinguishes the flaming of the incense stick by disposing the solid body close to the incense stick to shift it to the glowing. By applying this method to an automatic ignition incense burner, perfumed smoke is generated by automatically shifting the flaming of the incense stick after automatic ignition to the glowing.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combustion (hereinafter referred to as "flameless combustion") in which an incense burning with a flame (hereinafter referred to as "flame combustion") is present only at a solid surface without a flame. ) And an auto-ignition incense burner which automatically generates flammable combustion by automatically igniting the incense to automatically generate flameless combustion.

[0002]

2. Description of the Related Art Since incense sticks utilize gas generated by flameless combustion, it is necessary to shift from flaming combustion to flameless combustion after ignition of the incense stick. For this purpose, a person usually ignites the incense to burn it with flame, and then blows the flame in such a way as to shake or inhale the incense to blow off the flame and shift to flameless combustion.

However, when the conventional method is used to automatically shift the incense to flameless combustion, there is a disadvantage that the apparatus becomes complicated.

[0004]

The problem to be solved by the present invention is a method of shifting the burning of incense sticks to flameless combustion (hereinafter referred to as a flameless combustion transition method), and a method of automatically igniting after burning. This is the development of an auto-ignition incense burner that generates smoke by transferring flame-burning incense to flameless combustion.

[0005]

According to the method of the present invention, a solid is placed in close proximity to or in contact with the incense stick, so that the solid takes advantage of the effect of cooling the flame, and the solid incense is used. It is characterized by extinguishing flame combustion and shifting to flameless combustion.

In the incense burner according to the present invention, the heating element control section (4) starts heating of the heating element (3) controlled by the heating element control section (4) and ignites the incense stick (2). The flame combustion is transferred to the flameless combustion by the method according to the present invention.

[0007] Regarding a flame of a gas mixture in which fuel gas and air are completely mixed (hereinafter referred to as a premixed flame), if the gas mixture is to be ignited by a spark, the spark must be generated by the spark. It is known that the interval has a lower limit (hereinafter, referred to as extinction distance). It is said that this is because the flame is cooled by the electrode and the flame cannot be propagated. This quenching distance is determined by the flame temperature,
It is said that it varies depending on the combustion speed and the like. Further, as for the solid material that cools the flame, a substance that absorbs heat has a higher flame cooling effect, but it is said that almost the same flame cooling effect can be obtained if the material is solid regardless of the material.

[0008] In a flame in which atoms and molecules of oxygen and fuel gas are mainly transported to a reaction zone by diffusion (hereinafter referred to as a diffusion flame), a solid placed close to the flame is similar to a premixed flame. However, the diffusion flame has a lower temperature and a lower combustion speed than the premixed flame,
A larger flame cooling effect can be expected from a solid placed in close proximity to the flame.

[0009] When the incense burns with flame, the flame is a diffusion flame. However, the flame is supplied by the pyrolysis of flammable combustion of the incense which is a so-called porous fuel originally manufactured to burn without flame. The amount of fuel gas supplied is small, and the flame temperature is lower than that of a general flaming combustion flame, so that a larger flame cooling effect by a solid placed close to the flame can be expected.

On the other hand, the effect of cooling of the flameless combustion portion exerted by a solid placed in proximity to the flameless combustion portion is very small. If the solid has high thermal conductivity, the effect is observed when the solid is close enough to contact the flameless combustion part. If the solid has heat insulation properties, it is possible to maintain flameless burning of the incense stick even when it comes into contact with the burning part.

Therefore, when a solid is arranged close to the incense stick, when the flame burning of the incense proceeds and approaches the solid, the flame is extinguished by the effect of flame cooling by the solid.
Since the solid does not extinguish the flameless combustion, the incense stick then shifts to flameless combustion, and the flameless combustion continues to be maintained.

If the flameless combustion transition method is used in an incense burner having a heating element (3) for igniting the incense, the incense ignited by the heating element starts flaming combustion, but the method of the present invention is used. Transition to flameless combustion by the solid (1) according to (1), and the flameless combustion continues to be maintained.

The heating element control section (4) controls the start of heating of the heating element (3). For example, the ignition switch is manually operated, the ignition switch is remotely operated, and the time switch is controlled. The incense can be automatically ignited by causing the heating element to generate heat when it senses the entry or the like. Further, the incense that is ignited by such means and starts flaming combustion is extinguished by the solid (1) and shifts to flameless combustion, thereby realizing an automatic ignition incense burner that generates smoke.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention realizes the purpose of easily and reliably achieving the purpose of shifting a flame-burning incense to flameless combustion by a simple method, and automatically igniting the incense. In addition, an incense burner that automatically and reliably generates smoke was realized.

On the other hand, in the state where the incense sticks A and B were set up vertically as in Example 1, the solid could not achieve the object of the present invention.
This is because the heat capacity of the solid was small, so that the flame rapidly heated the upper part of the solid, causing an updraft inside the cylinder before quenching, increasing the supply of air to the flaming combustion part of the incense stick This has resulted in an increase in flaming combustion, which has offset the effect of flame cooling. Therefore, the object of the present invention can be achieved even if the heat capacity is increased and the internal ascending airflow is prevented even if the solid has the shape.
