Abstract

The widespread use in modern life and in the restaurant production of induction cookers makes relevant the problem of computational and experimental study of the processes and phenomena that occur during their operation. It is of interest to compile a list of applied research problems of the processes and designs of induction cookers, the solution of which will be of interest from the point of view of improving the design solutions and operating modes of the investigated equipment. A review of literary sources showed that the authors of research on induction cookers ignored several important applied problems,namely: − study of the thermal state of the induction cookerin case of failure of its fan; − study of the distribution of the electromagnetic field ofthe cooker, as well as the processes of heating the dishes and the inductor of the cooker in the following situations: the heated dishes are not located in the center of the inductor of the induction cooker, but are partially offset and occupy part of the surface of the cooker not occupied by the inductor; dishes of smaller diameter than the diameter of the inductor are used; − study of processes in induction cookers and dishes heated at different field frequencies in the range of 20-100 kHz; − comparison of the distribution of the electromagnetic field of the cooker and the thermal field of the dishes in cases of the presence and absence of a magnetic core in the design of the plate, as well as a comparison of the processes when using a magnetic core made of various magnetic materials. The solution of these problems is proposed to perform using computer simulation of multiphysical electromagnetic and thermal processes, as well as experimentally.
