<p><P>PROBLEM TO BE SOLVED: To provide an electric stove safely providing heating effect with high heating efficiency and energy efficiency. <P>SOLUTION: A semiconductor ceramic heater having emissivity of 93% or more as a heating source is constituted to irradiate far infrared ray not including visible light at a surface temperature of 500°C or less. A human body can be directly heated without warming the air between the heater and the human body by radiation heating utilizing radiation heat of far infrared ray by black heating free from red heat, thus heating efficiency can be improved without excessively consuming electric energy to heat the ambient air, excessive consumption of electric energy can be prevented, and a risk of burn injury can be reduced by keeping a long distance between a heat source and the human body. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
