Title:
METHOD FOR SWITCHING HEATING DEVICES IN AN ELECTRICAL COOKING APPLIANCE AND CORRESPONDING DEVICE
Document Type and Number:
WIPO Patent Application WO2005074321
Kind Code:
A3
Abstract:
According to the invention, it is possible, for example, on a ceramic top (11), to increase the life expectancy of the timing relays (RT), for individual hobs (12), which are divided into groups (14) of more than one hob. The groups (14) are each provided with a phase-separation relay (RP), for connection to an external line on a three-phase supply. Supply to a line for a hob (12) can be achieved, by means of a controller (16), whereby as many current supplying timing or switching processes as possible are carried out by the phase separation relay (RP) and not by a timing relay (RT), provided for the hob.
