The present invention relates to a tubular far-infrared heater, and more particularly, the heat conduction guide plate is attached to the inside of the ship flue to increase the residence time of the exhausted heat source, thereby maximizing the heat transfer effect of far-infrared radiation and heat emission and improving combustion efficiency. A tubular far infrared heater that can be improved.

Infrared radiation is a kind of electromagnetic waves with a stronger thermal action than the red region of visible light. It is invisible, absorbed by materials, and has strong resonance and resonance effects on organic compound molecules. Emitted in the form of radiant heat from a heated object.

Infrared rays are rays located between the visible wavelength band and the wavelength band of microwaves. The infrared rays emit light in the wavelength range of 0.76 to 1.5 μm (760 to 1500 nm), and near-infrared rays and light in the range of 1.5 to 5.6 μm (1,500 to 5,600 nm). Infrared rays are classified into far-infrared rays in the region of 5.6 to 100 µm (5,600 to 100,000 nm).

In particular, when the infrared rays are irradiated to the human body by the heat ray effect of strong penetration force, the micro-vibration activates the cell tissues by vibrating the cells more than 2,000 times per minute, and the capillaries are expanded by the increase of body temperature caused by the heat energy. It promotes the formation of tissues and promotes the body's immune system by improving the body's constitution, which is acidified by pH synergism, and activates the immune system of the human body, thus preventing aging, reducing pain and promoting metabolism, inducing sleep, and chronic fatigue. It is known to have the same effect of preventing adult diseases, heavy metals and waste products by sweating.

In addition, since far infrared rays have the characteristic of raising the temperature at the same time as the inside and the surface, uniform heating and drying are possible, which shortens the heating time and saves energy. Therefore, it is applied to the field of heating and drying, and eliminates the bacteria that cause various diseases. As it helps to prevent germs and mold growth, deodorization and dehumidification, and air purification, it is applied to various fields such as housing and building materials, kitchen utensils, textiles, clothing, bedding, medical equipment, and jjimjilbang.

Far-infrared heater, unlike the conventional convection type heater or conventional heater of air heating method, is a method of directly irradiating far infrared rays to the human body, so it is not affected by wind and has a heating effect due to the excellent straightness of infrared rays. It is suitable for indoor use as well as for outdoor use because it has a long distance and has a large heating effect in the downward direction, and has been spotlighted as a next-generation heater due to the absence of dust, noise and odor due to the development of combustion technology.

1 is a front view of a general far-infrared heater 1 'of a cabinet type by white kerosene combustion, in which the tubular far-infrared heater 1' of the type shown shows a control and display panel 3 ', a burner 4', a fuel tank. (6 '), combustion chamber (7'), linear and arched flue (8 ', 8a') and exhaust filter section coated on the outer surface with a ceramic layer that emits far infrared rays when heated ( 9 ').

Above the casing 2 'is provided a control and display panel 3 which is operated by remote control operation, and inside the casing 2' a burner 4 ', its control unit (not shown) and an intake port (not shown). ) Is installed and the fuel tank 6 'is housed below the burner 4'.

When combustion is started from the burner 4 ', the flame 5' generated from the burner 4 'is extended to the inside of the combustion chamber 7' and combustion of fuel such as kerosene is continuously performed, and the combustion chamber 7 The flame inside ') heats the above-mentioned linear and arched flue (8', 8a ') along with the combustion gas by way of zigzag along the linear and arched flue (8', 8a '), and is therefore coated on the outer surface thereof. A large amount of far infrared is emitted by the far infrared radioactive ceramic coating layer. The linear and arched flue 8 ', 8a', which is formed zigzag and has an extended length, is heated to a high temperature so that unburned unburnt in the combustion chamber is instantaneously secondary burned in the process. This contributes to the increase of calorific value and contributes to the purification of exhaust gas.

In some cases, the traces of the fines contained in the combustion gas are tertiarily combusted and exhausted by passing through a catalyst filter (not shown) mounted in the above-described linear and arched flue 8 'and 8a'. Instant deodorization and purification can also be achieved.

An exhaust filter part 9 'is mounted at the end of the arch flue 8a' at the end, and an adsorption member (not shown) inside thereof adsorbs and collects a small amount of fine dust and harmful gas in the exhaust gas, Deodorization and purification are performed while evaporating gradually by the heat continuously obtained from the exhaust gas in a completely burned exhaust state, and in addition, a noise function is performed in part, thereby enabling more comfortable heating.

On the other hand, since the exhaust hole (not shown) for discharging high-temperature exhaust gas is formed at the outer end portion of the exhaust filter part 9 ', a guard net 9a' is installed to prevent hand burns due to carelessness. Although not shown, a safety net (not shown) is mounted on the front of the far infrared heater 1 '.

However, in the case of the conventional far-infrared heater as described above, the time that the burned heat source stays in the combustion chamber 7 ', the shipboard and the arch flue 8', 8a 'is short, so that the heat energy of the heat of combustion is not sufficiently transferred. However, since a large amount of thermal energy is released into the atmosphere through the shipboard and the arch year as it is, waste of thermal energy is severe and thermal efficiency is lowered, thereby increasing the fuel cost burden.

Accordingly, an object of the present invention is to form a tubular far-infrared heater that can maximize the heat transfer effect of far-infrared radiation and heat emission and improve combustion efficiency by lengthening the residence time of the heat source exhausted by attaching a heat induction guide plate inside the linear flue. To provide.

The tubular far-infrared heater of the present invention for achieving the above object, in the combustion chamber, the far-infrared radioactive material coated on the outer surface and the tubular far-infrared heater having a linear flue and an arch flue, the combustion chamber, the linear flue, and the arch Characterized in that the heat guide plate is attached to the inside of at least one of the year.

Here, the heat guide plate is preferably formed only in the linear flue.

In addition, the heat guide plate may be a single plate that is twisted in the shape of a pretzel in the longitudinal direction in the linear flue.

In addition, a plurality of heat induction guide plate of the pretzel type may be formed by dividing the section in the longitudinal direction within the linear flue.

In addition, the heat induction guide plate may be a plurality of inclined heat induction guide plate is formed alternately in the longitudinal direction along the inner surface of the linear flue, inclined protrusion in the heat flow direction.

In addition, each end of the plurality of inclined heat guide plate is preferably spot welded to the inner surface of the linear flue.

In addition, each other end of the plurality of inclined heat guide plates may be bent inward or outward.
