Description

[Detailed Description of the Invention] This invention relates to a heater using a combustion flame that generates heat and emits light, such as an kerosene stove or a gas stove, or a heater that uses a red-hot body that emits heat and emits light.
For example, it is used to enhance the heating effect of a heater using an electric stove, and emits heat rays and warm color rays suitable for large amounts of heating to the outside of the heater, and
The combustion tube disperses and interferes with the light emitted from the combustion flame and red-hot body to generate various colors, making the combustion tube shine in rainbow colors.

That is, in the figure showing an example of an oil combustor, 1 is a combustion tube forming the outer shell of the combustion chamber, 2 is a combustion device that performs white-yellow flame combustion, and 3 is a combustion tube formed on the surface of the combustion tube 1. The coating 4 is an oil tank, and the oil in the oil tank 4 is burned with a white-yellow flame by the combustion device 2 in the combustion chamber to generate heat and light.

5 is combustion. 6 is the top and bottom knob.

The combustion tube 1 is made of a transparent or semi-transparent heat-resistant material such as porcelain or glass, and has a metal coating or a metal compound coating formed on its surface. As the main component of the coating, titanium, zirconium, iron, etc. alone or in combination are preferably used because of their ease of adhesion.

The coating can be formed directly by vapor deposition, in which the coating material is heated and evaporated in a high-temperature vacuum and adhered to the glass surface as a thin film, or it can be formed directly by heating the glass that forms the combustion tube to near its softening temperature. A metal salt compound may be dissolved in water or an organic solvent and sprayed onto a heating cylinder, and the metal chloride decomposes and oxidizes on the surface of the combustion cylinder to form a metal oxide film.Specifically, heat-resistant Metal or metal compound, 0.1~
The goal is to form an extremely thin film with a thickness of 0.5μ that does not impair transparency.

Conventionally, as this type of combustion tube, combustion tubes made of transparent glass, porcelain or glass containing fine particles are known. When we measure the wavelengths transmitted through these combustion tubes, we find that among the warm color rays and heat rays that are suitable for heating, the wavelength of about 3μ, which is particularly suitable for heating, is 2/3 to 3/4
Although the detailed analysis of this phenomenon is not clear, it is thought that the OH groups contained in the glass are the cause, and unstable OH groups on the surface and inside of the glass are absorbed. It is thought that this is because the energy of light changes into energy of heat.

By the way, in this invention, when the coating 3 is formed, the combustion tube 1 is
Because the unstable OH groups on the surface combine with metals and metal compounds, light with a wavelength of about 3μ, which is particularly effective for heating as heat rays, is easily transmitted without being absorbed by the combustion tube 1, and as shown in Figure 2. Since the refractive index of the coating 3 itself is strong, the 3μ light enters the combustion tube 1 at a small angle.
The angle of incidence of light with a wavelength of approximately The angle of the light is always close to a right angle,
The apparent thickness of the combustion tube 1 is reduced.

In particular, the angle of incidence of light on the combustion tube 1, which is positioned so as to surround the combustion flame and the red-hot body, is mostly small, and even when the incident angle is small, the light almost passes through the combustion tube 1. Since the light is transmitted at right angles, absorption of light by OH groups in the combustion tube 1 is reduced, and light with a wavelength of about 3μ, which is effective for heating, is not absorbed by the combustion tube 1 and can be transmitted well. .

Furthermore, the wavelength at which coating 3 exhibits strong reflection characteristics is
Infrared rays of 5μ or more have little effect because the transmission performance of the combustion tube 1 itself is originally degraded, and it is possible to obtain a combustion tube 1 with an excellent heating effect.

On the other hand, since the coating 3 is very thin, the coating thickness is not constant and some unevenness can be seen.When visible light is reflected on the combustion tube 1, the light reflected by the metal coating 3 and the metal coating 3 are mixed. The light that passes through and reflects on the glass surface interferes with each other, and certain wavelengths are weakened or strengthened, so the reflected image of the combustion flame appears colored, and the thickness of the metal coating 3 changes. The wavelengths that are weakened or strengthened also change, resulting in various colors being emitted. In addition, when the combustion flame is repeatedly reflected two or three times on the inner surface of the combustion tube 1, several reflected images of the combustion flame are generated, which can be seen multiple times, and these images are colored rainbows of red, yellow, and green. It is recognized as a shaped flame, so it looks extremely beautiful.

In addition, the occurrence of a large number of reflected images in the combustion tube 1 in this way means that there are apparently as many combustion flames or red-hot bodies as there are reflection images, and even if there is only one combustion flame or red-hot body, it cannot be identified. The direction of light that reaches one point is from many directions, as if there were many heat generating and light emitting parts, so the number of shadow areas is reduced and an effective lighting effect can be expected.

In addition, since the combustion tube is formed with a ring-shaped surface unevenness, the unevenness expands into a lens shape, instead of making the heat generation part appear to be multi-stage. It has the effect of getting recognition.

As described above, the present invention uses a simple structure in which a metal coating or a metal compound coating is formed on a transparent or translucent combustion tube to allow heat rays of the wavelength most suitable for heating to pass through well, and the coating also makes it possible to prevent combustion flames from burning. By interfering with the generated light, images of many colored combustion flames and red-hot bodies are formed, and the heat rays generated from the combustion flames and red-hot bodies can reach from multiple directions.
In addition, the lens effect created by the ring-shaped uneven parts enhances the heating effect.Furthermore, the images of the many colored combustion flames and red-hot bodies are very beautiful, enhancing the visual heating effect, and the intersection of light. This creates an excellent design effect.
