Induction hob and method for manufacturing the induction hob

Abstract

An induction hob and a method of manufacturing an induction hob are provided, wherein the induction hob (1) comprises an upper main surface (15) and a lower main surface (16) presenting, in use, on which at least one pan to be heated can be placed. ), coupled to at least one inductor (2) on the body (14) at the lower major surface (16), and fixed to the lower major surface (16) of the body (14) adding the inductor (2) ) on the flexible body (9); the flexible body (9) includes alternating first electrically insulating layers (4) and second layers (20) respectively including at least one conductive track (5); the inductor (2) includes a A plurality of conductive tracks on different second layers (20) and electrically connected to each other in series and / or parallel to form a plurality of loops extending in the same direction around a central axis substantially perpendicular to the upper major surface (15) (5).

Description

technical field [0001] The invention relates to an induction hob and a method for manufacturing the induction hob. It should be noted that, in the context of the present invention, the term "hob" may refer to a finished product ready for the market (that is to say equipped with a control interface and / or electronic control equipment) or only its active part, ie Say, only the mechanical structure and the inductor part are included. Background technique [0002] Induction hobs are well known systems that replace conventional gas stoves or electric heating element cookers, allowing heat to be generated directly in the ferromagnetic base of the pan. [0003] Typically, an induction hob comprises a body (also commonly referred to as a hob or top) having an upper surface on which a pan to be heated can be placed. While in most induction hobs on the market the body is formed from a flat plate of electrically insulating and antimagnetic material such as glass, ceramic or glass-cer...

AI Technical Summary

Problems solved by technology

[0012] It is easy to understand how the two construction methods of the prior art are relatively complex and expensive, especially since they almost inevitably require considerable labor, especially for the more complex case where the hob includes a large number of inductors

[0013] Second, despite the construction equipment mentioned above, there is always a clear risk of breakage with prior art hobs due to the way they are designed

[0014] Also, prior art induction hobs are relatively heavy and bulky objects given the complexity of the associated structures

[0015] Finally, it should be noted that on a scientific level, the article "Printed circuit board inductors for domestic induction heating" by I. Lope et al., page 245 of HES-13 Electromagnetic Source Heating Professional Conference also covers inductors integrated in printed circuit boards Inductors are the subject of a possible use in a domestic environment as a replacement for common Litz wire inductors, but apparently without significant results in industry
