Abstract

PURPOSE:To provide an electric heater of which whole surface of a metallic and porous front panel is beautifully brightened, by inclining the metallic and porous panel upward in the radiating direction of a radiant back panel. CONSTITUTION:Emitted visible rays and infrared rays from a high temperature heater element 7 in the direction of a reflective back panel 6 are reflected by the back panel 6, becoming parallel-going rays, and are emitted forward. Because an aluminum honeycomb 8, consisting of a metallic and porous panel, is inclined upward, the parallel rays pass through cells 8a, reflected by the walls of cells 8a of an aluminum honeycomb panel 8. In addition visible rays and infrared rays emitted directly forward from the high temperature radiant heater element 7 pass through the cells 8a, reflected by the walls of cells 8a of an aluminum honeycomb panel 8 as well. All emitted visible rays and infrared rays from the high temperature radiant heater element 7 pass through the cells 8a, reflected by the walls of cells 8a of an aluminum honeycomb panel 8. Accordingly whole surface of the aluminum honeycomb panel 8 is beautifully brightened, and it gives a warm feeling to a user.

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.

Conventional technology A conventional example is shown in FIG.

In FIG. 2, 1 is a stove body, 2 is a reflector, 3 is a high temperature radiant heater, and 4 is a metal porous member.

The metal porous member 4 has a shape as shown in FIG. 3, and some of the visible light and external light emitted from the high-temperature radiant heater 3 travel straight through the cells 4a of the metal porous member 4. However, a part of the light passes through the cell 4a while being reflected by the wall surface of the cell 4a.

Therefore, the entire surface of the metal porous member 4 provided on the front surface of the high-temperature radiant heater 3 shines beautifully, giving a warm feeling. As shown in FIG. 4, the high temperature radiant heater 3 uses a tungsten alloy for the heater wire 1o, uses a quartz tube for the outer tube 11, and seals an inert gas inside, and the temperature of the heater wire is 1000° C. A lamp heater set to 1500'C is used, which is brighter than an electric wire heater.

While the invention is trying to solve the problem: The key point is that visible light emitted from a high-temperature radiant heater
A part of the external light rays is reflected by the reflector on the rear surface and exits to the front surface as almost parallel rays in the horizontal direction, so that it is not reflected on the wall surface of the cell 4a and does not contribute to the shine of the metal porous member 4.

The visible light and external light reflected on the cell walls are not reflected by the reflector emitted directly in front of the high-temperature radiant heater, so the cell walls near the high-temperature radiant heater shine brightly, but the ones far away shine brightly. The problem was that the walls of the cell had less shine, and the brightness was uneven and the entire surface did not shine uniformly.

The present invention solves these conventional problems and provides a beautiful electric stove whose entire surface shines beautifully.

Means to Solve the Problems The present invention which solves the above problems includes a high temperature radiant heater, a reflective plate behind the heater, and a metal porous member provided in front of the high temperature radiant heater so as to cover the heater. Equipped with
The metal porous member is arranged to be inclined upward with respect to the reflection direction of the reflection plate.

action The effect of this technical means is as follows.

In other words, visible light and external light rays emitted from the high-temperature radiant heater are reflected by the reflector on the back side, become parallel light beams, are reflected on the wall of the cell of the metal porous member provided at an angle on the front side, and are emitted upward. Refract and move forward.

The metal porous member is formed from a large number of fine reflective surfaces of thin plates, and is made of a highly reflective material, so it has good reflectance and good refraction.

In other words, all visible light and external light emitted from the high-temperature radiant heater are reflected on the cell walls of the porous metal member and refracted upwards, resulting in a uniform, beautiful, and beautiful shine over the entire surface. .

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

Since this embodiment has the above-described configuration, visible light and external light emitted from the high-temperature radiant heater 7 in the direction of the reflector 6 are reflected by the reflector 6, become parallel light rays, and are emitted forward.

And an aluminum no-nikum member 8 which is a metal porous member.
For example, since it is tilted upward, the parallel light rays pass through the cell 8a while reflecting off the wall surface of the cell 6a.・Cell 81 of Nikum member 8
It passes through the cell 8a while being reflected by the wall of L.

Therefore, all of the visible light and external light emitted from the high-temperature radiant heater 7 pass through the cell 82L while being reflected by the wall surface of the cell 82L of the aluminum non-nicum member 8, so the aluminum non-nicum member 8 The entire surface shines beautifully and gives a warm feeling.

Furthermore, since the aluminum no-nikum member 8 is tilted upward, all the external light reflected by the reflector 6 is refracted upward, thereby preventing an excessive rise in temperature of the floor surface and improving safety.

Effect of the invention According to the present invention, the following effects can be obtained.

(1) Visible light and external light emitted from the heater are
All of this is reflected on the cell walls, so the entire surface of the metal porous material shines evenly and beautifully, improving interior design and creating a sense of warmth.

(2) Since the direction of reflection by the metal porous member changes upward, it is possible to prevent excessive temperature rise on the floor surface and improve safety.

(3) The narrow metal comb 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.
