Quick starting method of variable-frequency microwave oven, and readable storage medium

Abstract

The invention provides a quick starting method of a variable-frequency microwave oven. The method comprises the following steps: S1, controlling the filament current of a magnetron, enabling a filament to quickly emit heat so as to quickly emit microwaves, and taking the cut-off feedback regulation quantity of the filament power as the compensation quantity of resonant cavity parameters and magnetron state parameters; and S2, controlling the anode voltage of the magnetron, adding the compensation amount obtained in the step S1 on the basis of the off-line calibration parameters to serve as the starting frequency, and gradually increasing then the frequency so as to achieve quick starting of the microwave oven. The invention further provides a readable storage medium. The method has the beneficial effects that the starting time is stabilized, power overshoot is reduced, incoming material control is not needed, and rapid and accurate starting of the frequency conversion microwave oven can be well achieved.

Description

technical field [0001] The invention relates to a frequency conversion microwave oven, in particular to a quick start method and a readable storage medium for a frequency conversion microwave oven. Background technique [0002] Frequency conversion microwave oven is to adjust the output microwave power by adjusting the output frequency. It is characterized by fast heating speed. For example, fresh milk only needs to be heated for about 10 seconds. The heating time must be very precise. It usually takes about 5 seconds to start the frequency conversion microwave oven. Firstly, the time for starting each time should be fixed, and secondly, the set power should be reached quickly and the overshoot should be small. [0003] According to the system model of the resonant cavity, off-line calibration of start-up parameters is one of the best methods to solve the start-up problem. However, in actual application, the input voltage varies (165V-265V), the difference and dispersion o...

AI Technical Summary

Problems solved by technology

[0005] 1. When the resonance parameter deviation is large, the filament current and the anode voltage are out of adjustment, and the start-up time becomes slow or the overshoot is large;

[0006] 2. When the magnetron is cold, it starts slowly; when the magnetron is hot, it starts quickly, and the start time is not fixed;

[0007] 3. The control of incoming materials increases the process and increases the cost
