<p><P>PROBLEM TO BE SOLVED: To provide an induction cooking device capable of making inside components invisible from an infrared transmission window of an infrared sensor. <P>SOLUTION: The induction cooking device includes a top plate 2 which mounts a cooking vessel 3 and through which infrared rays transmit, a heating coil 4 for induction-heating the cooking vessel 3, an infrared sensor 5 for intercepting the infrared rays radiated from the cooking vessel 3, a controlling means 8 for controlling a power supply to the heating coil 4 based on a detected temperature of the infrared sensor, a dot printing unit on which an innumerable number of dots DT formed on the surface of the top plate 2 and made of a material capable of shielding visible light and infrared rays, and an infrared transmission window 30L which is surrounded by the dot printing unit and is to be an infrared transmitting passage to the infrared sensor 5. The dot printing unit in the periphery area of the infrared transmission window 30L has a numerical aperture to suppress transmission of the visible light and the infrared rays and the dot printing unit in the infrared transmission window 30L has a numerical aperture to allow transmission of the visible light and the infrared rays. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
