Bread making apparatus and its temperature control method

Abstract

In a temperature controlling method of a kitchen-heating apparatus having a temperature sensor at a certain place in the heating area, the temperature control is performed by comparing a temperature detected by the temperature sensor with a set temperature. In this case, an acceleration of the temperature ascent and descent at each certain interval is required and the temperature of the above heating portion is controlled with a duty ratio which corrects the duty ratio of the above heating portion of each interval with the acceleration of the temperature ascent and descent in the front step. In another temperature control method, the point of time where the ascent of the sensor detecting temperature due to the heater being on turns to descend together with a time lag due to the heater being off is detected, and performs the control again by turning the heater on at an earlier point of time than the point where at least the sensor detecting temperature comes down to the set value of the sensor detecting temperature.
