COOKING TEMPERATURE CONTROL SYSTEM

摘要

An automatic temperature control for cooking includes a temperature sensor (6) for detecting the temperature of the outer bottom surface of a container (4) being heated. A temperature rise gradient of the temperature sensor (6) established at a given time in the initial stage of heating is used as a temperature correction value peculiar to the container (4), while a temperature rise gradient of the temperature sensor (6) established after a certain temperature has been reached is used as a temperature correction value for the amount of food being cooked. The former and latter temperature correction values are converted into preset temperature values and serve as operating temperatures for the temperature sensor (6). …When the temperature sensor (6) reaches the operating temperature, the heating rate is controlled to hold the operating temperature. Thus, the system performs automatic temperature control irrespective of the kind of the material, wall thickness and size of the container, by means of the temperature rise gradients of the temperature sensor so as to ensure that the preset temperature and the temperature of the food are equal.
