Intelligent microwave heating method and device

Abstract

The invention discloses an intelligent microwave heating method and device. The heating method comprises the following steps of S1, obtaining a geometric model and the attributes of a heated object; S2, calculating the heating frequency and the heating time of the heated object according to the geometric model and the type of the heated object; and S3, heating the heated object according to the heating frequency and the heating time. According to the intelligent microwave heating method, the geometric modeling of the heated object is automatically obtained, the attributes of the heated objectare judged, and then the heating frequency and the heating time are further calculated, so that the dynamic change characteristic of the heated object along with time is fully considered, the accuracyof frequency selection is improved, the intelligent heating process is achieved, and the degree of dependence of the heating process on people is reduced.

Description

technical field [0001] The invention relates to the field of microwave heating, in particular to an intelligent microwave heating method and device. Background technique [0002] With the rapid development of modern science and technology, microwave energy, as a new type of high-efficiency and clean energy, has been widely used in various fields such as industrial production and daily life. [0003] The existing microwave oven has the problem of poor heating uniformity of the object to be heated. In order to solve this technical problem, in the application of the prior art, the heating uniformity is improved by changing the microwave frequency to be heated (such as a frequency conversion microwave oven), but it is often achieved by simply sweeping the frequency within a frequency band Frequency conversion still has the problem of low microwave absorption rate of the object to be heated, that is, low heating efficiency. The recently publicized "A Device and Method for Micro...

Problems solved by technology

[0004] The existing technology mainly has the following major shortcomings: first, the geometric modeling process of the heated object needs to be completed manually, and the specific size setting is required, and the process is relatively cumbersome; second, the dielectric properties of the heated object need to be manually input, Since the dielectric properties of the substance will change dynamically during the heating process, this method will cause a poor match between the calculated results and the actual results to a certain extent while the degree of intelligence is poor.

Since the existing method obtains the optimal frequency through pre-calculation, as the heating time goes by, when the pre-selected frequency deviates from the actual preferred frequency, the output frequency cannot be adjusted in time, which will affect the heating uniformity and Further improvement in efficiency
