Abstract

The present invention provides a heating cooker capable of further efficiently heating cookware to be heated that is made of a low-permeability material. This heating cooker comprises an induction heating coil 6 and an infrared heater 19 for heater heating. A heating power controller determines the material of the cookware 8 to be heated and controls an inverter and a heating element conducting section according to the material determined, thereby controlling the heating ratio between the induction heating coil 6 and the infrared heater 19. A temperature detection part 11 is disposed inside the infrared heater 19 forming a ring-like shape; and a heater installation member 17 is so structured that its side wall 17a prevents an infrared ray radiated from the infrared heater 19 from reaching the temperature detection part 11.

Description

technical field

[0001] The present invention relates to a heating cooker including a heating unit including an induction heating coil and an infrared heater for heating a cooking container placed on a top plate constituting an upper surface of a casing. technical background

[0002] In an induction heating cooker, how to heat a cooking vessel made of a material with low magnetic permeability and high conductivity such as an aluminum pot or a copper pot has become a problem. As a conventional technique for solving this problem, Patent Document 1 discloses a configuration that detects the floating or movement of the pan due to the repulsive force generated during induction heating, and limits the current supplied to the induction heating coil. In addition, Patent Document 2 discloses a configuration in which an aluminum plate is inserted between an induction heating coil and a pan, and the pan is indirectly heated by induction heating the aluminum plate.
