Abstract

PURPOSE:To improve a safety of an electric stove without reducing a warm characteristic, expand a range of expansion of warm condition and make a surface-like glittering and beautiful unit by a method wherein a radiation heat of a heater is passed through a space while the heat is reflected against a wall surface of the cell part of honeycomb member. CONSTITUTION:Infrared ray including visible light radiated from a hot radiation heater 7 is operated such that its part is advanced straight through the cell part 8b of aluminum honeycomb member 8 and the other part is passed through the cell 9b while it is reflected at the wall surface of the cell part 8b. Therefore, an entire surface of the aluminum honeycomb member 8 arranged at a front surface of the hot radiation heater 7 shows a glittering and beautiful appearance, gives a warm characteristic, prevents a longitudinal loss of the radiation heat in the heater 7 and generates an expansion toward the direction perpendicular to that of the beam. With the foregoing, an antire surface of the metallic hoenycomb member shows a glittering and beautiful appearance, prevents a radiation heat of the longitudinal direction, generates an expansion of the heat in a perpendicular direction and can heat the foot from the lateral part. The heater is protected by fine metallic hoenycomb member, prevents a human finger or combustibles from being directly contacted with the member, resulting in ensuring a high safety of the unit.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an electric stove using a high temperature radiant heater that emits radiant heat including visible light.

A prior art example (Japanese Unexamined Patent Publication No. 58-142128) is shown in FIG. In Fig. 4, 1 is a main body, 2- is a reflector, 3 is a lamp heater, and 4 is a transparent plate made of a material that transmits infrared rays, such as heat-resistant glass, and its front surface has an uneven shape, for example, in the shape of a square heel. is formed.

When the lamp heater 3 is energized, the heat rays pass through the transparent plate 4, are refracted at the front surface of the transparent plate 4, which has an uneven shape, and are diffused into the room. It has the effect of alleviating irritation to the eyes.

In addition, since the lamp heater 3 is covered by the transparent plate 4, it is safe because fingers and combustible materials do not come into direct contact with the lamp heater a, and the light is diffused on the front surface of the transparent plate 4, which has an uneven shape. The entire surface of the translucent plate 4 shines even when viewed from an angle, making it look beautiful and at the same time warm.

Problems to be Solved by the Invention However, there is currently a problem in that there is no material suitable for a transparent plate used in such a configuration. That is, the heat-resistant glass exemplified in the conventional example generally has a low transmittance for infrared rays having a wavelength of 2.7 μm or more, which reduces the warmth of an electric stove.

The present invention solves these problems of the conventional technology, and provides an electric stove that improves safety without reducing warmth, spreads warmth, and has a beautiful shining surface.

Disappear.

Means for Solving the Problem The electric stove of the present invention includes a high-temperature radiant heater, a reflector behind the heater, and a metallic honeycomb member provided in front of the heater to cover the heater. The radiant heat passes through the space while being reflected on the wall surfaces of the cell portions of the honeycomb member.

Function Since the electric stove of the present invention has the above-described configuration, all the energy including visible light and infrared rays emitted from the high-temperature radiant heater passes through the honeycomb member without being absorbed, and is absorbed into the cells of the electric heater. The entire surface of the honeycomb member shines beautifully due to the reflection on the wall of the heater, and the honeycomb member also acts to prevent fingers and combustible materials from coming into contact with the heater.

EXAMPLE Hereinafter, an electric stove according to an example of the present invention will be described with reference to the drawings. In FIGS. 1 and 2, 5 is the main body, 6 is a reflector, 7 is a high-temperature radiant heater that emits visible light and infrared rays, and 8 is an aluminum honeycomb provided in front of the heater 7 so as to cover the heater 7. It is a member.

FIG. 3 shows details of the aluminum honeycomb member 8.

The aluminum honeycomb member 8 is formed by gluing together a large number of thin aluminum foils 8ae to form a large number of hexagonal cells 8b, where b is the cell dimension and t is the thickness of the honeycomb member. In this example, the cell size ib is approximately 3 fl, and the honeycomb member thickness t
= 5 m, and the thickness of the aluminum foil 8a is approximately 30 μm.

Furthermore, in the high temperature radiant heater 7 of this embodiment, a tungsten alloy is used for the heater wire, a quartz tube is used for the outer tube, and an inert gas is sealed inside, so that the temperature of the heater wire is set at too'c to 15
A lamp heater heated to 00°C is used. Therefore,
Brighter than electric wire heaters used in general atmospheric environments.

Since this embodiment has the above-mentioned configuration, part of the infrared rays including visible light emitted from the high-temperature radiant heater 7 travels straight through the cells 8b of the aluminum honeycomb member 8, and part of the infrared rays go straight through the cells 8b of the aluminum honeycomb member 8.
It passes through cell 8b while being reflected by the wall of cell 8b. Therefore, the entire surface of the aluminum honeycomb member 8 provided in front of the high-temperature radiant heater 7 shines beautifully, giving a warm feeling, and in fact prevents unnecessary loss of radiant heat in the longitudinal direction of the heater 7 and prevents it from spreading in the right angle direction. bring about

In particular, in the case of an electric stove that uses the heater 7 vertically as in this example, it is possible to prevent the floor surface temperature from rising, so the heater 7 can be installed near the floor surface and have the effect of warming the feet from the side. .

In fact, the honeycomb member 8 acts as a guard for the heater 7, preventing people's fingers or combustible materials from coming into contact with the heater 7, and there is no object through which heat rays can pass, such as the conventional light traveling plate 4. , there is no decrease in energy due to a decrease in transmittance.

Effect of the invention The following effects can be obtained by the present invention.

(1) The entire surface of the metallic honeycomb member shines beautifully, improving interior quality and increasing the sense of warmth.

■ Prevents unnecessary radiant heat in the longitudinal direction of the heater, causing expansion in the right angle direction. Therefore, when using the heater vertically, it is possible to prevent the floor surface temperature from rising excessively and to warm the feet from the sides.

■ A narrow metal honeycomb member guards the heater,
It is highly safe because it completely prevents people's fingers and iJ flammable materials from coming into immediate contact with the heater.

) Since there is no object to pass through, there is no reduction in energy due to transmittance.
