A method for judging the amount of rice in an electric rice cooker

Abstract

The invention discloses a method of rice quantity judgment of a rice cooker. The rice cooker is provided with a fixed temperature value of rice quantity judgment and an inner-top temperature value atthe time of a cold pot. An actual temperature value of rice quantity judgment is the sum of the fixed temperature value of rice quantity judgment and a correction temperature value of rice quantity judgment when a temperature value at the time of starting of rice quantity judgment of the rice cooker is greater than the inner-top temperature value at the time of the cold pot, and the correction temperature value of rice quantity judgment is difference of the inner-top temperature value at the time of the cold pot and the temperature value at the time of starting of rice quantity judgment. According to the method, the inner-top temperature value at the time of the cold pot and the actual temperature value of rice quantity judgment are additionally set on the basis of the prior art, the actual temperature value of rice quantity judgment is adjusted according to the temperature value at the time of starting of rice quantity judgment, and thus the rice cooker can accurately judge, accordingto time taken for heating to the actual temperature value of rice quantity judgment, rice quantity to achieve a satisfactory rice cooking effect.

Description

technical field [0001] The invention relates to daily necessities, in particular to an electric rice cooker. Background technique [0002] One of the main functions of the electric rice cooker with microcomputer control is cooking, and its control core is a single-chip microcomputer. The cooking function is controlled and realized by a single-chip microcomputer program. In order to ensure that the rice can be cooked well under the large and medium amount of rice, it is necessary to judge the amount of rice in the rice cooker. According to the judgment result of the rice amount, different process control programs are used to avoid overflow during the cooking process. , sticky bottom, sandwiched raw and other abnormalities, and achieve good aroma, taste, shape and color of rice grains. [0003] The process of judging the amount of rice is: start heating and timing after the low-temperature water absorption process of cooking rice (at this time, the top temperature in the ele...

Problems solved by technology

If the amount of rice is originally medium, it will be misjudged as the amount of millet. If the amount of rice is originally judged as the amount of medium rice or even millet, the average heating power of the cooking program will become smaller when the judged amount of rice becomes smaller. When the actual amount of rice in the pot is medium, the cooking time will be very long, and the cooking effect is poor, and it is easy to cause the rice to be caught.
