Food unfreezing method of microwave oven

Abstract

The invention relates to a food unfreezing method of a microwave oven, wherein a sensor probe of the microwave oven measures the food temperature simultaneously with a plurality of sampling points; the food unfreezing method comprises the following steps: a temperature sensor and a controller are initialized; the temperature sensor measures through the plurality of the sampling points; the highest temperature and the lowest temperature are worked out through comparison; the measured highest temperature and the measured lowest temperature are respectively compared with the set upper limit and the set lower limit of the temperature, and the microwave oven is controlled to work according to the comparison results; and if the measured highest temperature is lower than the upper limit of the temperature and the measured lowest temperature is also lower than the lower limit of the temperature, an object needs to be continued to be unfrozen, the power level of the microwave oven is adjusted according to the lowest temperature, the step of measuring with the plurality of the sampling points is executed again, until the unfreezing is suspended, so as to ensure the object has the best unfreezing 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.
