<p><P>PROBLEM TO BE SOLVED: To provide a heating cooker in which sufficient fire power can be obtained and heating to an abnormal high temperature can be prevented. <P>SOLUTION: The heating cooker is equipped with a memory circuit in which a first control temperature corresponding to an inverter circuit fire power set by an operating part is memorized, a first temperature control means of controlling to stop or make small output of the inverter circuit when a detected value of a temperature detecting means exceeds the first control temperature and to make the output of the inverter large when the temperature detected by the temperature detecting means reaches the first control temperature or less, a temperature difference calculating means of calculating the temperature difference between the detected value of the temperature detecting means and a target temperature renewed at every prescribed time, a temperature gradient calculating means of calculating a time change amount of the detected value of the temperature detecting means, a second temperature control means using a fire power determining means to determine the fire power of the inverter circuit by making a calculated value of the temperature difference calculating means and the temperature gradient calculating means as the input, and a loading amount discriminating means. When it is discriminated that there is a load, the fire power is controlled only by the first temperature control means. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
