PURPOSE:To provide the cooker with weighing functuon of high economic property by a method wherein the weight of a food is transferred to a string as the tension thereof and the oscillation frequency of the string is measured to measure the weight of the food. CONSTITUTION:Weights, applied to the weight transfer strings 15, are concentrated to an oscillating string 16 through pulleys 31 or the like. A correlation exists between the oscillating frequency of the oscillating string 16 and the tension thereof and the weight of the food can be measured by the oscillating frequency. The oscillating frequency of the string is detected by a microphone 18 and the string is snapped upon measuring by a snap means. A pluck weight 32 is attracted by a coil and the oscillating string 16 is plucked by the pluck weight when an electric current is cut off. The correlation between the oscillation frequency and the weight is memorized in a micro-computer, the weight of the food is obtained from the measured oscillation frequency besed on the memorized correlation. The optimum heat cooking may be effected by eighter indicating the measured weight in an indicating section or controlling the period of time and output of heating based on the measured weight. |
