Measuring method for unfrozen object in microwave oven

Abstract

The invention relates to a measuring method for an unfrozen object in a microwave oven; a sensor probe of the microwave oven measures the food temperature with a plurality of sampling points simultaneously; a temperature sensor defines the initial position of the food as a measurement result at 0 DEG C, and simultaneously judges the number of the sampling points of the temperature sensor on the object; afterwards, a tray carries out the same judgment every time when rotating for a certain angle, until the tray rotates for one week, and the size of the food is finally worked out. The shape, the size and the position on the tray of the object are worked out by recording the position information of the sampling points on the object to be heated in the microwave over in different angles, and then the temperature rise of all the points is judged according to the positions of the effective sampling points of the tray in a first round, so as to effectively distinguish the target temperature and the background temperature in the unfreezing process.

Description

technical field [0001] The invention belongs to the technical field of microwave ovens, and specifically relates to a method of recording the position information of sampling points at different angles on an object to be heated in a microwave oven to obtain the shape, size and placement position of the object on a tray, so that it is easier to control thawing Process for the measurement of thawed objects in a microwave oven. 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, because the object to be thawed does not always have a uniform physical condition and the same physical characteristics, the temperature value of the object obtained by the sensor through a single sampling point is not true. During the thawing process, due to the uneven temperature rise of the target object, it cannot Accurately distinguish the temperature of the object and the background temperature. The temperature sensor cannot accurately obtain the temperature distribution of the food to be thawed, so it cannot objectively judge the thawing effect of the food. During the thawing process, it will always cause over-thawing or under-thawing.
