Description

[0001] The present invention relates to a far infrared radiation heater using biofuel,

The present invention relates to a far-infrared heater using biofuels, more specifically, it can reduce the generation of dangerous gases in the human body by using clean biofuels, and is easy to move and has excellent radiation efficiency of far infrared rays, The present invention relates to a far-infrared heater using a biofuel having excellent safety by preventing the heater from being automatically burned when vibration is applied to the heater or when the heater is inclined.

In winter, various heating devices are used in places where people gather such as a home, a pension, an office, a factory, a golf course, a restaurant, a church, and various businesses. In particular, the use of a heating device called a far-

On the other hand, recently widely used far infrared ray heater differs from conventional convection type air heater or air heating type conventional heater by radiating far infrared rays, and is not influenced by wind, and has excellent linearity of infrared rays As the heat dissipation distance reaches a long distance, it has excellent heating effect and can prevent air pollution during heating process.

As a result, it is widely used not only for indoor use but also for outdoor use, because indoor air can be maintained comfortably even when installed indoors.

However, the pellet far infrared ray heater configured as above has a problem that the fuel cost is high when the pellet far infrared ray heater is operated recently because a fuel tank is provided inside the main body and kerosene stored in the fuel tank is used as fuel.

In addition, since kerosene burns a large amount of carbon in the combustion process, it causes environmental pollution. Therefore, in developed countries such as Europe, the use of kerosene as a fuel for heating is reduced and the proportion of using alternative fuels such as wood pellets is gradually increasing.

In addition, in the case of the pellet far infrared ray heater, since the far infrared rays generated in the combustion process are all blocked by the heat radiation pipe, the amount of far infrared rays actually radiated is extremely small.

The reason for coating the diamond-like carbon (DLC) layer on the inner surface of the far-infrared ray transmission window 120, which directly contacts the flame 113 when the biofuel 112 is burned, is to provide heat resistance to be.

In addition, by coating the diamond-like carbon (DLC) layer, it is possible to prevent the far-infrared rays generated during the combustion of the bio-fuel 112 from being reflected to the inner surface of the far-infrared ray transmission window 120 can do.

Meanwhile, in order to more effectively prevent the far-infrared rays generated during the combustion of the biofuel 112 according to an embodiment of the present invention from being reflected to the inner surface of the far-infrared ray transmission window 120 without being emitted to the outside, An anti-reflection layer is further coated between the window 120 and the diamond-like carbon (DLC) layer.

At this time, the anti-reflection layer may be coated using various methods or materials, and therefore, the anti-reflection layer is not limited thereto.

In addition, the far-infrared ray transmission window 120 according to an embodiment of the present invention may include a portion of the far-infrared ray transmission window 120, more specifically, a flame 113, so as to smoothly burn the bio- A plurality of air inlets 122 are formed at the height where the air is introduced.
