Control method of electric cooker applicable to different altitudes and electric cooker applicable to the method

Abstract

The invention relates to a control method for an electric rice cooker applicable to different altitudes and the electric rice cooker, comprising a control unit and a heating unit, the control unit is composed of a single-chip microcomputer and a temperature measuring element, the single-chip microcomputer and the temperature measuring element are connected in a circuit, and the electric rice cooker is suitable for different altitudes The electric cooker control method comprises the following steps: A). Start the boiling point judging program of the control unit; B). The control unit runs the boiling point judging program, and obtains a value T2, and the T2 is stored in the control unit; C). When the rice cooker is working normally, the control unit reads the constant value T2 as the default boiling point temperature. When the above method is applied to different altitudes again, the boiling point judging program of the control unit is restarted. At this time, according to different altitudes, the boiling point judging program calculates a different constant value T2', then T2' is the default boiling point temperature of the altitude . The invention automatically cooks according to different boiling point temperatures. Including plateau cooking compensation, accurate temperature measurement, saving time, reducing burning or jamming.

Description

[0001] technical field [0002] The invention specifically relates to a control method for an electric rice cooker applicable to different altitudes. [0003] Background technique [0004] At sea level, the boiling point of water is 100°C. As the altitude increases, the boiling point of water will gradually decrease, and the boiling point of water at different altitudes is also different. At present, the cooking process of an ordinary electric rice cooker is generally: first, the rice absorbs water on a low fire, then boils the liquid until the liquid boils, and finally stews the rice with a slow fire after the liquid is dried up; to a certain temperature (generally 80°C), and then heat intermittently over low heat. Because the altitude in the plateau area is higher than the sea level, its boiling point is lower than that of the sea level. Generally, the boiling point drops by 1°C when the altitude rises by 300m. Ordinary electric rice cookers all set the boiling point t...
