DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flame reaction member for a combustion appliance, and more particularly to an improvement of a flame reaction member for coloring a flame in response to a flame ignited by a fuel gas ejected from the combustion appliance. is there.

[0002]

2. Description of the Related Art Conventionally, a flame reaction member is provided near a fuel gas ejection portion of a burning appliance such as a lighter or a torch, and a flame ignited by a fuel gas ejected from the fuel gas ejection portion is colored in various colors. There has been proposed a technique for improving the appearance. (See, for example, Japanese Utility Model Laid-Open No. 60-86761).

[0003] However, the flame reaction member in the invention disclosed in the above-mentioned publication is a member in which a flame reaction product is applied in a small amount on a support, and has a drawback that the color development duration is short.

To solve this difficulty, Japanese Patent Laid-Open Publication No.
As disclosed in Japanese Patent Publication No. 13718, a plurality of fine wires are twisted to form a support having a stranded wire structure, and a metal oxide such as Cu ₂ O or B ₂ O ₃ exhibiting a flame reaction (a flame reaction product). There is a flame reaction member obtained by immersing the support in a solution containing the metal oxide and then baking the support to which the metal oxide is applied. According to the flame reaction member, the flame reaction product is firmly fixed to the stranded structure of the support and the amount of the flame reaction is large, so that there is an advantage that the color development duration can be extended.

Further, as shown in JP-A-3-75413, one wire is wound in a coil shape to form a winding portion,
There is a flame reaction member coated and filled with a flame reaction product even to the inner part of the winding portion. According to the flame reaction member, a sufficient amount of the flame reaction product is held.

[0006]

However, some of the flame-colored reactants, due to their unique properties, increase in temperature and become fluid when exposed to a flame, and fall off from the support due to external force such as vibration. There is a problem of doing.

Further, since the flame reactant is filled up to an unnecessary portion of the support, there is a problem that the heat capacity of the flame reaction member as a whole increases and the rise time of color development becomes longer.

Further, as in the case of the support disclosed in Japanese Patent Application Laid-Open No. Hei 3-13718, twisting a plurality of wires is time-consuming and increases the production cost.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and is intended for use in a burning appliance provided with a support capable of favorably supporting a flame-colored reactant which is heated to generate fluidity upon heating during use. It is an object to provide a flame reaction member.

[0010]

According to the present invention, there is provided a flame-color reaction member for a combustion appliance, which utilizes a flame color reaction by a flame of a fuel gas disposed near a fuel gas ejection portion of the combustion appliance. In the flame reaction member for a combustion appliance comprising a flame reaction product for coloring the flame reaction product and a support for supporting the flame reaction product, the support is formed by spirally winding a wire material in two or more layers. The flame-colored reactant is carried and filled on the contact winding of the spiral winding portion.

It is also preferable that the flame-colored reactant is made of a material that is melted by heating, and is supported on the spiral wound portion of the support in a substantially spherical shape by surface tension.

[0012]

The flame reaction member for a combustion appliance according to the present invention is a flame reaction product on a support having a spiral wound portion formed by closely contacting two or more wires with a spiral wound portion. The spiral wound portion and the flame reactant are engaged with each other, so that the flame reactant can be prevented from dropping from the support even by external force such as vibration during heating in use, Further, since the flame-colored reactant is carried only on the necessary portions, the heat capacity of the flame-colored reaction member as a whole is small, and therefore, the color rise time can be shortened.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a flame reaction member for a combustion apparatus according to the present invention.

FIG. 1 is a plan view showing one embodiment of a flame reaction member for a combustion appliance of the present invention, FIG. 2 is a side view thereof, and FIG. 3 is a writer using the flame reaction member for a combustion appliance of the embodiment. FIG. 4 is a side view of FIG. As shown in FIGS. 3 and 4, both ends of the flame color reaction member 30 for a combustion tool shown in FIG. 3 are fixed to the inner peripheral surface of a base 42 provided above the gas outlet of the lighter 40, and upward from the gas outlet. Flame reactant 20 that exhibits a flame reaction by a flame ignited by the ejected fuel gas 20
And a support 10 supporting a flame-colored reactant 20. More specifically, as shown in FIGS. 1 and 2, the support 10 is made of a single wire, and the double-wound loop portion 12 to which the wire is in close contact is linearly opposite to the tangential direction of the loop portion 12. The loop portion 12 is filled with a flame-colored reactant 20 that completely covers the loop portion 12.

Further, specific examples of the material, dimensions, shape, etc. of the flame reaction member 30 for a combustion appliance will be described. The support 10 is made of a material NiCr, a wire diameter of 0.2 mm, a winding diameter (outer diameter) of the loop portion 12 of 1.1 mm, and two turns (close winding). The outer diameter of the flame reaction product 20 is approximately 1.8 mm.

The flame reaction member 30 for a combustion appliance formed in this way is heated by the flame igniting the fuel gas ejected from the gas outlet of the lighter 40, and the flame reaction product 20 is heated to cause a flame reaction. This produces chromogenic flame.

Further, the flame-colored reactant 20 applied to the inner winding of the loop portion 12 of the closely wound double winding is filled with the flame even if it is exposed to a flame and the temperature rises and the fluid reacts somewhat. Thus, it is possible to prevent the support body 10 from easily falling off due to external force such as vibration.

The flame reaction member 30 for a combustion appliance of the present embodiment
Since the loop portion 12 is formed in a part of the support body 10, the material is reduced compared to a conventionally used support body in which a loop is formed over the entire support body. For example, it is not necessary to perform a twisting process as compared with a support made by twisting two wires each having a wire diameter of about 1.5 mm, thereby facilitating the manufacturing and reducing the number of manufacturing steps.

Further, when the support 10 is fixed to the base 42, the central loop portion 12 is always positioned below the both ends 11 extending linearly in the tangential direction by its own weight.
Is stable with respect to the base 42, and the assembling work can be facilitated.

The flame-colored reactant is, for example, a type exhibiting a bluish-green flame-colored reaction, which becomes substantially spherical due to surface tension when solidified by heating and solidified by cooling and firmly adhered to the support. It is desirable to use.
