Description

Heater with improved far-infrared radiation effect The present invention relates to a heater with an enhanced far-infrared radiation effect, wherein the heater is characterized by having excellent heat dissipation performance and far-infrared radiation emission performance by including graphene. Generally, a heater is an electric heating device used to heat fluids such as air or water by passing an electric current through a conductor to generate heat, and it is applied to various types of electronic products such as washing machines, coffee pots, and heaters. In this regard, for heaters used to boil water, physical properties such as corrosion resistance and wear resistance are required to prevent corrosion; similarly, for heating heaters used to heat air, a ceramic coating is applied to the surface of the heater's heating rod to improve mechanical and chemical properties and prevent the heater from oxidizing in the air. Taking washing machines as a representative example of a home appliance where heaters are applied, a heater is used to supply hot water to enhance the cleaning power of clothes. However, when synthetic detergents containing various surfactants are used, problems arise such as corrosion and damage to the heater's heating rods or the formation of scale on the rods' surfaces, which hinders proper heat transfer to the water. In addition, when used in applications such as stoves, boilers, and saunas, if the human body approaches the heat source, burns or other injuries often occur due to the high heat. This is a problem caused by the low heat dissipation performance of conventional heating rods, which cannot widely dissipate heat in a short period of time. If the heat generated from the heat source has excellent heat dissipation performance, the above-mentioned problem can be solved. Meanwhile, far-infrared heaters are widely used in medical devices, as well as in household and industrial applications, as long-wavelength infrared rays penetrate the human body or objects to achieve heating. A typical far-infrared heater is configured such that insulation material and a heater coil are housed within a case of a certain size, and a front panel coated with far-infrared rays is provided in front of the heater coil. In a conventional example, an insulating material made of ceramic is filled inside an aluminum case, and a heat sink is manufactured by aluminum casting to house the heater coil. However, far-infrared heaters manufactured by this method are equipped with a separate heat sink designed to house a heater coil, which not only entails manufacturing inconvenience due to a complex configuration but also raises concerns about reduced efficiency of the device as the initial heating time required to heat above a certain temperature increases due to heat transfer occurring through conduction by the heat sink. Accordingly, while conducting research to solve the above-mentioned problem, the inventors developed a heater comprising a heating element and graphene mixed with or coated on the outside of the heating element. By discovering that the heater possesses excellent heat dissipation and far-infrared radiation emission performance by including graphene, the inventors completed the present invention. In this regard, Korean registered patent No. 10-0963224 discloses a ceramic-coated heater capable of being used in water or air.
