Food defrosting method for microwave oven

Abstract

The invention discloses a food defrosting method for a microwave oven, wherein a sensor probe of the microwave oven measures the temperature of a food by using a plurality of sampling points. The method comprises the following steps of: initializing a temperature sensor and a controller, measuring the temperature from the plurality of sampling points by using the temperature sensor, obtaining thehighest temperature and the lowest temperature by contrast, comparing the highest temperature and the lowest temperature with a set upper limit temperature and a set lower limit temperature, controlling the running of the microwave oven according to the comparison result, and if the measured highest temperature is lower than the upper limit temperature and the measured lowest temperature is also lower than the lower limit temperature, continuing defrosting the food until the defrosting is stopped by regulating the power level of the microwave oven according to the lowest temperature to re-measure the temperate from the plurality of sampling points, so that the object can be defrosted with the optimum effect.

Description

technical field [0001] The invention belongs to the technical field of microwave ovens, and in particular relates to a food for a microwave oven that measures the temperature of objects to be thawed at multiple points through multiple sampling points, and uses the measured minimum and maximum temperatures to simultaneously control the thawing steps to ensure that the objects can obtain the best thawing effect Thawing method. technical background [0002] A microwave oven is a device in which a magnetron generates microwaves after the power is turned on, and irradiates these microwaves on food and other heated objects to cook food. Such microwave ovens are classified into domestic microwave ovens equipped with small magnetrons and commercial microwave ovens equipped with large or multiple magnetrons. Microwave ovens can also be divided into household microwave ovens that generally use a glass turntable that rotates food, and commercial microwave ovens that mainly use a diffu...

Problems solved by technology

In fact, since the object to be thawed does not always have uniform physical conditions and the same physical characteristics, the temperature value of the object obtained by the sensor through a single sampling point is not true, and the temperature sensor cannot accurately obtain the temperature distribution of the food to be thawed. It is also impossible to objectively judge the thawing effect of food, and it will always cause over-thawing or under-thawing during the thawing process.
