Abstract

PURPOSE:To make it possible to obtain warmth receiving effect by visual sensa tion by reflecting the radiant heat radiated from the electric resistor of an electric room heater which employs a glass heater by means of a heat reflecting film to concentrate the radiant heat to one direction and at the same time providing a light source in the inside of the outer frame. CONSTITUTION:On one side of a sheet 1 of transparent heat-resistant glass an electric resistor 2 is provided, and on one side of a sheet 3 of heat-resistant glass a heat ray reflecting film 4 which consists of metallizing layer film through which light rays in the infrared light ray range can pass is provided to cover the whole surface, and the electric resistor 2 and ray reflecting film 4 are arranged to face each other. When the electric resistor 2 and a light source 6 are energized, the element 2 generates heat and radiates radiant heat. Out of this radiation heat that which is radiated to the side of the heat ray reflecting film 4 is reflected by the film 4 and the radiant heat is concentrated an the face on the side of the glass sheet 1. Furthermore, light of color in the orange-yellow color group is emitted from a light source 6, and it is reflected by a reflection plate 7 and it makes irregular reflection in the inside and goes out through the glass sheet 1 and glass sheet 3.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric heater using a glass heater in which an electric resistor is applied to a transparent heat-resistant glass plate.

BACKGROUND ART Conventionally, this type of electric heater has had a configuration as shown in FIG. That is, two transparent heat-resistant glass plates 1010
Between these two transparent heat-resistant glass plates 101 and the carbon-based electrical resistor 1, carbon-based electrical resistors 102 having a certain width are continuously arranged at regular intervals.
02 is in close contact. Furthermore, the outer periphery of the heat-resistant glass plate 101 is held by an outer frame 103, and this outer frame 103 has legs 1.
04 was fixed, and the heat-resistant glass plate 101 was erected vertically.

Problems to be Solved by the Invention In such a conventional configuration, since the heat-resistant glass plate 101 holding the electric resistor 102 is transparent, the opposite side can be seen through the gap between the electric resistors 102, which is interesting. On the other hand, when the electric resistor 102 is energized to generate heat, radiant heat is radiated to both sides, which reduces the heating effect on one side by half.
No. 2 does not emit red heat, so there are problems in that no visual effect of warmth can be obtained and the energization status cannot be determined.

The present invention solves these problems. - The opposite side of the surface can be seen through, and the radiant heat can be concentrated in the direction of the surface, thereby increasing the heating effect. It is an object of the present invention to provide an electric heater that can display the energization state as well as obtain the desired effects.

Means for Solving the Problems In order to solve this problem, the present invention provides a glass heater in which a see-through electrical resistor is provided on one side of a transparent glass plate, and a glass heater in which an electric resistor in the infrared region is placed on one side of the transparent glass plate. A heat-reflecting glass coated with a heat-reflecting film that reflects light with wavelengths shorter than the infrared range and transmitting light with wavelengths shorter than the infrared range is disposed such that the electrical resistor and the heat-reflecting film face each other; A light source is provided inside an outer frame that holds the glass heater and the heat ray reflective glass.

Effect With this configuration, of the radiant heat emitted from the electric resistor, the radiant heat emitted to the heat ray reflective film side is concentrated in one direction, and the outer frame that holds the glass heater and the heat ray reflective glass is concentrated in one direction. The light emitted from the light source provided inside is diffusely reflected inside and goes out through the glass heater and heat-reflecting glass.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, on one side of a transparent heat-resistant glass plate 1, an electric resistor 2 made of a transparent tin oxide film is applied over the entire surface. In addition, one side of the transparent heat-resistant glass plate 3 reflects light with a wavelength in the infrared region, that is, light with a wavelength of 0.7 μm or more, and light with a wavelength shorter than 0.7 μm, that is, light with a wavelength that includes visible light. A heat ray reflecting film 4 made of a transparent metal vapor-deposited multilayer film is applied over the entire surface of the glass plate 1.
The glass plates 3 are arranged parallel to each other at a certain interval, and moreover, the electric resistor 2 and the heat ray reflective film 4 are arranged to face each other. Further, the glass plate 1 and the glass plate 3 are held by an outer frame 6, and a light source 6 that emits orange-yellow light is provided inside the outer frame 6, that is, at the bottom of the glass plate 1 and the glass plate 3. light source 6
A reflecting plate 7 is provided at the bottom of the. Furthermore, legs 8 are fixed to the bottom of the outer frame 5, and the glass plates 1 and 3 are vertically erected.

In the above configuration, when the electrical resistor 2 and the light source 6 are energized, the electrical resistor 2 generates heat and emits radiant heat. Of the radiant heat radiated, the radiant heat radiated to the glass plate 3, that is, the heat ray reflective film 4 side, is reflected by the heat ray reflective film 4, so the radiant heat radiated from the electric resistor 2 is transferred to one surface of the glass plate 1 side. concentrated in the direction of Furthermore, orange-yellow light is emitted from the light source 6 and is reflected by the reflector plate 6.
It is diffusely reflected inside, passes through glass plate 1 and glass plate 3, and goes out to the outside.

Effects of the Invention As is clear from the description of the embodiments above, according to the present invention, the radiant heat radiated from the electric resistor provided on the transparent glass plate is reflected by a transparent heat ray reflecting film provided on the transparent glass plate. By reflecting the light and concentrating it in one direction, you can collect heat more efficiently than in one direction, and still maintain the fun of being able to see through the glass plate to the other side. Furthermore, the light emitted from the light source provides a visual effect of warmth, and also has the effect of displaying the energized state.
