Abstract

The device has a cooking area(s) with cooking zones, a visual residual heat indicator and a counter for switching the display off after a delay following switch-off of the mains voltage. A detector detects application of mains voltage. Information is placed in memory while a counter state exceeds null. The residual heat indicator remains active after a mains interruption depending on the memory contents if the information in memory exceeds null. The device has at least one cooking area (2) with cooking zones (4) that become hot when switched on, a visual residual heat indicator (6) that advises of hot zones when the device is connected to mains voltage and a counter for switching the display off after a delay following switch-off of the mains voltage. A detector detects application of mains voltage to the cooker. Information is placed in a memory while the counter state exceeds null and the residual heat indicator remains active after a mains voltage interruption depending on the memory contents if the information in memory exceeds a counter value of null. AN Independent claim is also included for the following: a method of operating a residual heat indicator for an inventive electrical device.
