Description

Detailed Description of the Invention [Industrial Application Field] The present invention is a method of printing and welding a heating element to a tempered roll glass having a large number of curved uneven surfaces, and applying electricity to the heating element to generate heat. This invention relates to a far-infrared heating device that heats a living room by generating far-infrared rays to create a comfortable thermal environment indoors and to save energy.

[Prior Art] Conventionally, a heating device is known in which a planar heating element is attached to the back side of a ceramic plate, and when the heating element is energized, far infrared rays are emitted through the ceramic plate.

[Problems to be Solved by the Invention] However, in many of the conventional heating devices described above, the surface temperature of the ceramic plate is 300°C or higher (in the mid-infrared range), which is too high for use as a heating device for a living room.
There was a problem that it was unsuitable due to the risk of fire and burns.

The present invention was made with attention to the above problems, and by lowering the surface temperature, heat rays in the far infrared region are emitted, and by increasing the radiation angle as much as possible, the heat rays can spread over a wide area in the room. The purpose of this project is to obtain a far-infrared heating device that can be used for a long time.

[Means for Solving the Problems] The present invention provides a wire-like structure by welding silver and aluminum alloy powder in the form of printed wiring to the back surface of a heat-dissipating glass plate made of tempered rolled glass on which a large number of curved uneven surfaces are continuously formed. While forming a heating element, the linear heating element is energized to set the surface temperature of the heat dissipation glass plate at 150 to 170°C,
By generating far infrared rays on a heat dissipating glass plate and making it possible to radiate this at a large radiation angle,
The above problems have been resolved.

[Function] According to the device of the present invention configured as described above, a prism effect is produced by providing a large number of curved concave and convex surfaces of small width in series on the heat dissipating glass plate, and it is also possible to energize the linear heating element. As a result, a heat-generating effect is generated, and due to the synergistic effect of the prism effect and the heat-generating effect, the surface temperature of the heat-radiating glass plate is heated to 150 to 170°C, and far-infrared rays are generated that increase indoor heating efficiency.

[Example] An example of the present invention will be described with reference to FIGS. 1 and 2.

A heat-dissipating glass plate 3 made of reinforced rolled glass is fixed to the inner circumferential side of the battery case cover frame 1, and the heat-dissipating glass plate 3 is made of reinforced rolled glass and has a large actual radiation surface by continuously forming a large number of curved uneven surfaces 2 with extremely small widths. A linear heating element 4 is formed by welding silver and aluminum alloy powder in the form of printed wiring over the entire back surface of 3, and a power cord 5 is connected to the end surface of the linear heating element 4 to generate linear heat generation. The body 4 is energized to generate heat. Then, an insulating paint 6 made of silicone is applied onto the linear heating element 4 to protect it. Further, numeral 7 in the figure is a concave guard for preventing the heat dissipating glass plate 3 from falling, and both ends of the guard are fixed to the battery case cover frame 1.

Next, the operation of the above configuration will be explained.
The linear heating element 4 is energized to generate heat, which heats the heat dissipating glass plate 3 and generates far infrared rays.
Furthermore, the curved uneven surfaces 2 continuously formed on the surface of the heat dissipating glass plate 3 produced a prism effect in the radiation angle, and as a result, a radiation angle of 160° could be obtained. As a result, the surface temperature of the heat dissipating glass plate 3 is heated to 150 to 170°C, and the generated far-infrared rays have a wide radiation angle of 160° and spread over a wide area indoors. In addition, in order to set the surface temperature of the heat dissipation glass plate 3 to 150 to 170°C, a linear heating element 4 welded to the heat dissipation glass plate 3 in the form of a printed wiring is used.
Set the surface temperature with a resistor according to the design of
For further safety, a limit switch is added to this to prevent the surface temperature from rising above the set temperature.

As a result of the actual measurement, the thickness of the heat dissipation glass plate 3 is
6.35 mm, the linear heating element 4 is energized to generate heat,
When the surface temperature of the heat dissipating glass plate 3 was set at 160°C, far infrared rays in the wavelength range of 7 to 8 μm were generated.
This wavelength range of 7 to 8 μm has a particularly high absorption rate among far infrared rays by the human body and organic substances, and is therefore said to have extremely high heating efficiency, and this confirms the performance of this heating device. .

[Effects of the Invention] Since the present invention is as described above, the surface temperature of the heat dissipating glass plate can be set lower than that of conventional heating devices, thereby generating far-infrared rays that are most effective for room heating. The far infrared rays generated by this device have the characteristic of directly penetrating the target person or organic material and warming them by penetrating deeply into the body. , and because re-radiation occurs from high-temperature parts of the room to low-temperature parts,
The indoor air temperature is almost uniform everywhere.

For these reasons, the heating device of the present invention can provide a comfortable indoor thermal environment, and at the same time, it is possible to set the indoor temperature by 2 times compared to other hot air or hot water heating devices.
The temperature can be lowered by ~3℃, leading to energy savings.
