Abstract
A method for assembling an induction heating device includes the steps of interposing at least one ferrite bar between a coil assembly and a support plate, and snap engaging a central polymeric fastening element on the support plate. At least one end of the ferrite bar is inserted in a radial seat of the central polymeric fastening element. The coil assembly is snap engaged with the central polymeric fastening element in order to sandwich the ferrite bars between the support plate and the coil assembly.
Claims20
An induction heating device, comprising:
- a planar central element having a plurality of radial seats;
- at least one ferrite bar, wherein each of the radial seats is dimensioned to receive an end of the at least one ferrite bar with a predetermined degree of interference so that the at least one ferrite bar extends radially from and centered on the planar central element;
- a base disposed below the planar central element;
- and
- a coil assembly disposed above the planar central element, opposite the base;
- wherein the at least one ferrite bar is radially retained by the respective radial seat of the planar central element, and wherein the at least one ferrite bar is vertically retained between the coil assembly and the base.
