Embodiment Construction
[0028] Below, describe in detail the present invention in conjunction with accompanying drawing
[0029] Such as figure 1 As shown, a method for collecting temperature in a microwave oven cooking cavity of the present invention is characterized in that it includes the following steps:
[0030] 1) read and store the initial temperature values of n infrared temperature sensors arranged in the cooking chamber of the microwave oven, where n is a natural number greater than or equal to 8;
[0031] Firstly, the software / hardware of the system is initialized, and then the initial temperature values of n infrared temperature sensors arranged in the cooking cavity of the microwave oven are read and stored.
[0032] 2) Collect and store the temperature values of n infrared temperature sensors arranged in the cooking chamber of the microwave oven according to the set time;
[0033] The set time is to collect the temperature values of n infrared temperature sensors every 0.5 sec...

The invention relates to a method for acquiring temperatures in a cooking cavity of a microwave oven. The method comprises the following steps of: reading and storing initial temperature values of n infrared temperature sensors arranged in the cooking cavity of the microwave oven; acquiring and storing temperature values of the n infrared temperature sensors according to set time; subtracting the initial temperature value initially acquired from each infrared temperature sensor from the temperature value acquired from the infrared temperature sensor currently to acquire a difference value when temperatures are acquired every time; setting a comparing reference temperature value according to the temperature values acquired in the step 2 of the n infrared temperature sensors; comparing the temperature difference values acquired in the step 3 of the n infrared temperature sensors with the comparing reference value set in the step 4; identifying the sensors at effective positions; tracking the temperature values fed back by the sensors at the effective positions in real time; and regulating the supplied temperatures according to the temperature values. The optimal temperature for heating food can be supplied to the cavity of the microwave oven by an acquisition method for changing the temperatures fed back by the infrared temperature sensors.
Description
technical field [0001] The invention relates to a method for collecting temperature in a microwave oven cooking cavity. In particular, it relates to a method for collecting the temperature in the cooking cavity of the microwave oven, which can collect the temperature in the cooking cavity of the microwave oven in real time and distinguish the temperatures of food, containers and glass turntables. Background technique [0002] Generally speaking, after the food is put in and sealed in the microwave oven, the power is turned on to the magnetron that can generate high-frequency waves, and the resulting microwaves are irradiated on the food, so that the molecules that make up the cooking food vibrate within 24 seconds. A cooking machine that uses the frictional heat generated to cook food by 150 million times. [0003] Microwave ovens are easy to control the temperature. Since all parts of the food can heat at the same time, they can evenly cook foods of different sizes and sha...
