Induction heating cooker

Abstract

Provided is an induction heating cooker which prevents overheating of a pan whose bottom is warped to protrude and a pan having a thick bottom. The induction heating cooker is provided with a heatingcoil (2) for inductively heating a cooking container; an inverter circuit (7) for supplying the heating coil with a high frequency current; an infrared sensor (3) for detecting an infrared ray radiated from the cooking container; a power integrating section (81) for integrating a heating power outputted from the inverter circuit; and a heat control section (82) for controlling output from the inverter circuit. When the integration value obtained by the power integrating section is less than a prescribed value when an output increase quantity of the infrared sensor reaches a first prescribed value after heating is started with a first heating power, heat control mode is shifted to first heat control mode. When the integration value obtained at the power integrating section is at a prescribed value or higher, the heat control mode is shifted to second heat control mode. In the first heat control mode, the heating power is suppressed to a second heating power, which is lower than the first heating power. In the second heat control mode, heating is performed with a third heating power which is higher than the second heating power.

Description

technical field [0001] The present invention relates to an induction heating cooker for induction heating a cooking vessel. Background technique [0002] In recent years, induction heating cookers that induction-heat cooking containers such as pots and woks with heating coils have been widely used in general households and commercial kitchens. The induction heating cooker detects the temperature of the bottom surface of the cooking vessel, and controls the heating coil so that the detected temperature matches the set temperature. [0003] For example, in the induction heating cooker described in Patent Document 1, in order to detect the temperature of the bottom surface of the cooking vessel, a temperature detection unit is provided at a predetermined position on the lower surface of the top plate. This induction heating cooker first starts heating with a predetermined heating output, and temporarily stops heating when the temperature gradient of the bottom surface of the c...

Problems solved by technology

[0008] In this way, in the conventional induction heating cooker, the pan whose bottom is curved in a convex state and the pan with a thin bottom are overheated, and as a result, there is a problem that effective heating cannot be performed.
