When an electric current is applied to a printed matter with a density of ~ 3.5 m / m,
Heat starts to be generated from the center of the heat sink, and along with that heat is transferred to the ceramic powder on the surface of the heat sink to generate near-infrared rays first, enabling immediate heating, and then gradually heating from the center to the surrounding area. In addition to generating far infrared rays, heat is also transferred to the coating portion 13 of the fine shellac to generate negative ions and waves.

When the surface temperature of the heat radiating plate reaches a high temperature of 210 to 250 ° C., a controller (not shown) automatically operates to turn off the switch of 150 W connected to the upper power supply terminal unit 10, and only 350 W. In addition to trying to save energy, the surface temperature of the heat dissipation plate is as high as 210 to 250 ° C., so it is usually necessary to uniformly heat the room of 6 to 8 tatami mats with this heater.
