In general, the far-infrared heater, unlike conventional convection heaters or conventional heaters of the air heating method, is a method of directly irradiating the far infrared rays to the human body to generate heat, so it is not affected by wind and has excellent linearity of infrared rays. Due to its large heating effect, it is suitable for indoor use as well as for indoor use because it has a large heating effect on the down side, 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 10 of the cabinet type by burning kerosene, in which the tubular far-infrared heater 10 of the illustrated type is provided in a control and display panel 30 and a casing 20 operated by remote control operation. Burner 40 to be installed, fuel tank 60 accommodated below the burner 40, combustion chamber 70, the linear and arch type flue coated on the outer surface of the ceramic layer that emits far infrared rays during heating And an exhaust gas outlet 90 for exhausting the exhaust gas.

Here, reference numeral 50 denotes a flame generated from the burner 40 when combustion is started from the burner 40, and the flame is extended to the inside of the combustion chamber 70 while continuously burning fuel such as kerosene. The flame inside the combustion chamber 70 is heated on the outer surface of the linear and arched flue 80 and 81 while zigzag the linear and arched flue 80 and 81 together with the combustion gas, so that the flame is coated on the outer surface thereof. A large amount of far infrared is emitted by the far infrared radioactive ceramic coating layer.

In addition, reference numeral 91, which is not described, is provided as a protection net for preventing injuries of the hands due to carelessness in accordance with the discharge of the high temperature exhaust gas.

The wrinkles 151 are formed.

As shown in FIG. 2, the corrugated tubular far infrared heater 100 basically includes a casing 120, a lower box body 130, a burner 190, a fuel tank 132, and a ceramic layer that emits far infrared rays upon heating. It consists of the combustion chamber 140 coated on this outer surface, and the linear and arch type flue paths 150 and 180.

Above the casing 120, a control and display panel 121 operated by a remote controller is installed, and a burner 190, a control unit (not shown), and an intake port (not shown) are installed therein. It is substantially the same as the example of the heater 10 shown in FIG.

In order to improve heating efficiency by maximizing the far-infrared radiation and heat dissipation area, a plurality of wrinkles 151 are formed at regular intervals on the entire outer surface of the ship year 150. Although the surface area of the linear flue 150 is dependent on the height and depth of the ridges 152 and valleys 153 of the corrugation 151 by this configuration, generally speaking, the surface area of the linear flue 150 is increased compared to the case of simply configuring the smooth surface. The surface area can be provided, so that the heating efficiency also increases with the increase in the far-infrared radiation surface area and the heat dissipation surface area per unit length of the linear flue 150.

However, in the conventional configuration as described above, the multi-blown blower only presents a structure capable of performing forced circulation of heat flow by forced blowing, and the flame of the burner is heated to a high temperature of about 400 to 600 ° C. It is not possible to prevent the combustion chamber to be burned from glowing.

In addition, since the combustion chamber is burned and heated to a high temperature, torsion and reddening occur due to thermal expansion due to a temperature rise, which causes a serious problem in durability, thereby reducing the life of the device.

In addition, the combustion chamber is coated on the outer surface of the ceramic layer that emits far infrared rays when heated, there is a problem in that the ceramic coating layer is damaged when continuously heated to a high temperature to lose the radiation function of far infrared rays.

Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to install a multi-blown blower and a combustion chamber temperature sensor in a far-infrared heater, so that the phenomenon of redness of the combustion chamber due to high temperature during winter heating and Provided is a combustion chamber heat prevention apparatus of a far-infrared heater which can prevent a torsion phenomenon.
