Abstract

PURPOSE:To improve a safety of a unit without reducing a warm characteristic expand a warm range of heating and provide a surface-like glittering appearance by a method wherein a radiation heat of the heater is passed through a cell part while it is being reflected against a wall surface of the cell part of the honeycomb member and radiated forwardly from a cavity of the light shielding member. CONSTITUTION:Infrared ray including a visible light radiated from a hot radiation heater 7 is operated such that a part of the light is advanced straight through the cell part 8b of an aluminum hoenycomb member 8 and the other part is passed through the cell part 8b while it is being reflected against the wall surface of the cell part 8b. Then, the light is discharged forwardly from the cavity 9a arranged in the light shielding member 9. With the foregoing, the honeycomb member exposed to the cavity formed in the light shielding member shows a glittering outer appearance in a surface form, increases a warm characteristic. Since a shape of the cavity is not restricted in its manufacturing, it is possible to make a free design of a shape of the glittering and beautiful surface. It is possible to prevent a non-required radiation heat in a longitudinal direction of the heater, generate an expansion of the heat in a perpendicular direction, warm the foot from the lateral side. The fine metallic honeycomb member may guard the heater and prevent a direct contact of combustible, so that a high safety of the unit can be attained.

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. 6, 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. It 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 and radiated into the room. It has the effect of alleviating the stimulus given to the body.

In addition, since the lamp heater a is covered by the transparent plate 4, it is safe because fingers or combustible materials do not come into direct contact with the lamp heater 3, 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 warm at the same time.

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. In other words, the heat-resistant glass exemplified in the conventional example generally has poor transmittance for infrared rays having a wavelength of 2.7 μm or more, which reduces the warmth of electric stoves.

The present invention solves these conventional problems.The electric stove of the present invention improves safety without reducing warmth, spreads warmth, and has a beautiful electric heater that shines on a surface. The honeycomb unit includes a radiating portion, a reflecting plate behind the radiant portion, and a metallic radiator disposed in front of the heater so as to cover the heater, and the honeycomb unit includes a metal honeycomb member and the metal honeycomb member. and a light member that blocks a part of the light shielding member, and the radiant heat of the heater is not reflected on the wall surface of the cell portion of the honeycomb member, but passes through the cell portion, and is radiated forward from the cavity portion of the light shielding member. .

Function Since the electric stove of the present invention has the above-mentioned 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 by the cell portion of the heater. Reflection on the wall surface (because of this, the entire surface of the honeycomb member in the cavity formed in the light shielding member shines beautifully,
While creating a beautiful pattern, 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. 1, 2, and 3, 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 provided in front of the heater 7 so as to cover it. 9 is a rectangular honeycomb member made of aluminum; 9 is a light shielding member having an oblong cavity 9a formed in the center that closes a part of the honeycomb member 8; and 10 is a backing plate. As shown in FIG. 3, the honeycomb member 8 is sandwiched between the light shielding member 9 and the backing plate 1o, and the claws 9b provided on the light shielding member 9 are bent and fixed L to form the honeycomb unit 11.

FIG. 4 shows details of the aluminum honeycomb member 8.

The aluminum honeycomb member 8 is made by gluing together a large number of thin aluminum foils 8a 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 is approximately 3fl, and the thickness of the honeycomb member is 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, the heater wire is made of tungsten/alloy, the outer tube is a quartz tube, and an inert gas is sealed inside, and the heater wire temperature is set at 1000°C to 150°C.
A 0°CK heater/bubble heater 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. The light is then emitted forward from a cavity 9a provided in the light shielding member 9.

Therefore, the entire cavity 9a of the aluminum honeycomb member 8 provided on the front side of the high-temperature radiant heater 7, which is not covered by the light shielding member 9, shines beautifully. Further, since the light shielding member 9 is made of a plate-shaped metal, the shape of the cavity 9a can be freely formed by press working, and various designs as shown in FIG. 5 abc are possible.

That is, while using the honeycomb member 8, which is difficult to cut other than in a straight line, it is possible to freely form a beautifully shining surface including curved parts. Furthermore, the honeycomb member 8 prevents unnecessary radiation in the longitudinal direction of the heater 7 and causes the heater 7 to spread in the perpendicular direction. In particular, in the case of an electric stove that uses the heater 7 vertically in this embodiment, it is possible to prevent the floor temperature from rising, so the effect is that the heater 7 can be lowered to near the floor and the feet can be warmed from the side. There is.

Furthermore, the honeycomb member e acts as a guard for the heater 7, preventing people's fingers and combustible materials from coming into contact with the heater 7, and since there is no object through which heat rays can pass, such as the transparent plate 4 of the conventional example, There is no reduction in energy due to poor transmittance.

Effect of the invention The present invention can provide the following effects.

(1) The honeycomb member exposed in the cavity formed in the light-shielding member shines beautifully in planar form, improving interior design and increasing the sense of warmth. Furthermore, since there are no restrictions on the shape of the cavity in terms of processing, it is possible to freely design the shape of the beautifully shining surface.

(2) Unnecessary radiant heat in the longitudinal direction of the heater is blocked, 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.

(2) The narrow metal honeycomb member guards the heater and prevents people's fingers or combustible materials from coming into immediate contact with the heater, resulting in high safety.

(4) Since there is no object to transmit, there is no decrease in energy due to transmittance.
