Method for Accurately Detecting the Temperature of Grilled Food Used in Grilling Microwave Ovens

Abstract

A method for accurately detecting the temperature of grilled food used in a grill-type microwave oven. The following steps are completed in a microwave oven cavity with a grill equipped with a sensor array and a thermistor for measuring the air temperature in the cavity: initializing the sensor array, And preheat the microwave oven; judge whether the preheating is over; put in the food and select the corresponding heating method; scan the temperature of the sensor array and obtain the temperature of the thermistor; judge whether the deviation between the temperature of each sensor in the sensor array and the temperature of the thermistor is All are greater than 20 degrees; it is to remove the sensor with a deviation of less than 5 degrees and enter the barbecue heating; select the heating method according to the temperature; it is not to enter the barbecue heating; calculate the deviation 1 between the scan value and the scan value 1 minute ago, and the scan value and the current time Deviation 2 of the temperature value of the thermistor; determine whether deviation 2 minus deviation 1 is greater than 20 degrees. The invention has a simple structure, is easy to implement, can control the barbecue temperature more accurately, and improves the quality of the barbecue.

Description

technical field [0001] The invention relates to a microwave oven. In particular, it relates to a method for accurately detecting the temperature of grilled food used in a grill type microwave oven, which can accurately know the temperature of the food on the grill at any time. Background technique [0002] Generally speaking, a microwave oven is a machine that cooks food conveniently by turning on the power supply and using the microwave effect generated. In particular, recently, heating sources such as heaters have been installed in addition to magnetrons, and various cooking methods have emerged, that is, cooking methods that circulate the heat generated in the heaters, or cooking by controlling the position of the heaters. method etc. [0003] Such as figure 1 As shown, the existing microwave oven with barbecue is generally composed of the following components: a furnace body, which embraces the outside of the cooking chamber to form the entire appearance of the microw...

AI Technical Summary

Problems solved by technology

[0008] 1. A sensor probe is installed in the cooking cavity 200, but the sensor probe can only detect the air temperature in the cavity, and the surface temperature of the food can be roughly obtained, and the accuracy is extremely poor

[0009] 2. Use an infrared sensor, but the temperature of the furnace body is generally above 100 degrees when grilling, while the normal working temperature of the infrared sensor is 85 degrees, and the storage temperature is only 120 degrees, so the infrared sensor is easily damaged

[0010] 3. Judging the temperature of the cavity according to the time, there is no accuracy at all
