Barbecue control method of convective microwave oven

Abstract

The invention discloses a barbecue control method of a convective microwave oven. The method comprises the following steps: temperature determination is carried out within a predetermined time according to a program; a case that the voltage used by the microwave oven is large is determined by the program if the temperature in a cooking chamber is equal to or greater than a predetermined temperature; a new temperature lower than the predetermined temperature is automatically set; and then a barbecue tube stops working when an induction temperature reaches the new temperature, the barbecue tube begins to work when the temperature decreases to a temperature which is lower than the new temperature, and the stopping of the working of the barbecue tube and the working of the barbecue tube are repeatedly carried out until barbecue ending. According to the invention, an external voltage is determined through the determination of the practical temperature in the cooking chamber, and the result is direct; the set temperature is automatically reduced according to the program when the voltage is large in order to properly shorten the working time of the barbecue tube, so a heat radiation quantity equalization purpose is reached, phenomena comprising overheating, singeing and the like caused by the overhigh power of the heat radiation barbecue tube when the external voltage is overhigh are avoided, and the cooking quality is improved.

Description

technical field [0001] The invention relates to a convection microwave oven, in particular to a grilling control method for the convection microwave oven. Background technique [0002] At present, the theoretical voltage fluctuation of China's power grid is 10%, but the situation of the power grid is very complicated. Therefore, in different regions and time domains, the voltage may fluctuate greatly, which makes the electrical appliances work in ultra-high voltage or ultra-low voltage, which seriously affects the user. Electric safety. For example, due to unstable voltage, it may lead to excessive temperature rise of electrical appliances, which may cause fire in severe cases; and the harm of reducing the service life of electrical appliances due to unstable voltage is more extensive. [0003] Specifically for microwave ovens, in order to eliminate the influence of voltage on microwave heating or barbecue heating, Chinese patent 200520122181.1 discloses a microwave oven po...

AI Technical Summary

Problems solved by technology

If the voltage is too high, the actual power will increase, the actual temperature of the heat radiation grill tube will increase, and the radiated heat will increase. When cooking food at the same time, overheating may occur, which will affect the color and taste of the food.
