Description

[Detailed description of the invention] (Field of industrial application) This invention is based on a solid combustion material for flame viewing (for example, a main combustion agent such as metaldehyde, mixed with one or both of a flame coloring agent and a pyrotechnic agent, and This relates to a stand-type combustion appliance in which a solid combustion material formed and solidified in the shape of is installed and burned.

(Prior Art) The solid combustion material for flame viewing as described above has been known as the invention of Japanese Patent Application No. 136254/1983.
Furthermore, as a combustion appliance for solid combustion materials, one is known that has a stand-type main body that can be installed on a tabletop, and a dish-shaped combustion material installation part on the upper end of which the solid combustion material is placed and burned.

(Problems to be Solved by the Invention) However, the conventional stand-type combustion appliance is designed to ignite and burn the solid combustion material by placing it in surface contact with the flat plate surface at the upper end of the main body. Even if a solid combustion material with an air hole in the center is used, after a while after ignition, the solid combustion material becomes covered with combustion residue (combustion ash) and becomes difficult to burn, causing a bad odor due to incomplete combustion. and the generation of toxic gases. Moreover, if the combustion material is completely covered with combustion residue, the combustion will disappear in this state, and the problem will occur that the combustion material will remain without being completely burned.

(Means for Solving the Problems) In order to solve the above-mentioned conventional problems, this invention is designed to accommodate a solid combustible material 1 having a hole in the combustible material installation part 3 of the appliance main body 2 with an outer circumferential gap g. retained,
It is formed with a tapered surface 3a that expands upward at an appropriate angle, and the inside of the stand of the instrument main body 2 is formed as a fall receiving chamber 6 for the combustion residue 7, and the combustible material installation part 3 of the instrument main body 2 is formed. It is characterized in that an air intake hole 8 for introducing and supplying outside air to the central air hole 1a of the solid combustion material 1 is provided at a lower position.

(Function) When the solid combustion material 1 for flame viewing with the center hole 1a as an air hole is installed in the appliance body 2, the outer part of the installed combustion material 1 (the combustion material 1 and the tapered surface where it is installed) is installed in the appliance body 2. 3a) is formed to facilitate initial combustion, and the center air hole 1a of the installed combustible material 1 and the air intake hole 8 of the appliance body 2 are brought into communication so that outside air can be introduced. When the combustible material 1 is ignited and burned in this state, outside air is introduced into the main body 2 from the air intake hole 8 due to the suction effect caused by the rising action of the combustion gas (flame), and this introduced air is used as the central air of the combustible material 1. Since the combustion material 1 is supplied to the hole 1a, it is combusted sequentially from the top to the bottom. In this case, since there is an air hole 1a in the center of the combustible material 1, the flame 10 has an inner flame 10a and an outer flame 1.
0b becomes two, and these two flames 10a, 10b
can be beautifully viewed from the outside. Also,
The residue 7 generated by the combustion of the combustion material 1 is transferred from the center hole 1a of the combustion material 1 to the residue receiving chamber 6 in the main body base part 5.
It falls due to its weight and is stored in a state where it cannot be seen from the outside.

In the latter stage of combustion when the combustion material 1 has burned down to the lower part, the amount of air introduced into the lower combustion part from the taper upper end opening decreases, but the inner diameter of the combustion material center hole 1a (air hole) Because it becomes larger,
It is easier to burn from the center side, and it burns completely to the end without leaving any unburned residue.

(Example) Hereinafter, a specific example of this invention will be described in detail with reference to the drawings. This combustion appliance is equipped with a solid combustion material 1 for flame viewing, with a center hole 1a penetrating through the upper and lower ends as an air hole. It is a stand-type device that allows the combustible material installation part 3 of the main body 2 of the device to be directed upward at an appropriate angle (for example, an angle of 30 to 45 degrees).
A tapered surface 3a is formed which expands at 300 degrees, and the solid combustion material 1 is received in this tapered hole with an outer circumferential gap g, and the lower end outer peripheral edge contacts the tapered surface 3a with an inclined surface to form an upright surface as shown in the drawing. The internal space of the stand 5 of the instrument main body 2 is formed as a falling reception chamber 6 for combustion residue 7, and the instrument main body 2 is located at a lower position than the combustible material installation section 3. Central air hole 1a of solid combustion material 1
It is characterized by being provided with an air intake hole 8 for introducing and supplying outside air.

In this embodiment, the device main body 2 includes a conical container-shaped platform 5 with a closed bottom, a pipe support 4 erected from the platform 5, and a tapered upper end of the pipe support 4. This main body pipe support 4
One or more air intake holes 8 are provided in the lower peripheral wall of the main body 2, and the main body 2 has a drum-shaped combustible material installation portion 3 which is directly provided on the conical truncated portion 5 and expands in a tapered shape. In this case, the air intake hole 8 is provided on the circumferential side of the main body base 5 near the upper end.

When the solid combustion material 1 for flame viewing with the center hole 1a as an air hole is installed in the appliance body 2, the outer surrounding part of the installed combustion material 1 (the combustion material 1 and the tapered surface where it is installed) is installed in the appliance body 2. 3a) to facilitate initial combustion, and the center air hole 1a of the installed combustion object 1 and the air intake hole 8 of the appliance body 2 are in a state of communication so that outside air can be introduced. When the combustible material 1 is ignited and burned in this state, outside air is introduced into the main body 2 from the air intake hole 8 due to the suction effect caused by the rising action of the combustion gas (flame), and this introduced air flows into the central air hole of the combustible material 1. 1a. Therefore, the combustible material 1 burns sequentially from the top to the bottom. In this case, since there is an air hole 1a in the center of the combustion material 1, the flame 10
There are two types, the inner flame 10a and the outer flame 10b, and these two
The two flames 10a and 10b can be beautifully viewed from the outside. Further, the residue 7 generated by the combustion of the combustion material 1 falls under the weight from the center hole 1a of the combustion material 1 into the residue receiving chamber 6 in the main body base part 5, and is stored in a state where it cannot be seen from the outside. Therefore, post-processing can be easily performed without damaging the aesthetic appearance.

On the other hand, in the latter stage of combustion when the combustion material 1 has burned down to the lower part, the amount of air introduced into the lower combustion part from the opening at the upper end of the taper decreases;
Since the inner diameter of a (air hole) increases as it burns, it becomes easier to burn from the center side, making it possible to carry out complete combustion to the end without leaving any unburned residue.

(Effects of the invention) Since the stand-type combustion appliance of this invention has the above-mentioned structure, it does not have the problems of generating bad odors and toxic gases due to incomplete combustion as in the past, and eliminates the problem of combustion extinguishing due to the covering of the residue of combustion materials. It has the effect of completely eliminating the problem of burnt residue.
