Abstract:
A device for signaling at least one cooking state of at least one cooking item, such as an egg, a potato, a pepper, rice, noodles, in a liquid cooking medium, said device comprising an at least partially floating jacket, a temperature sensor arranged in thermally conductive communication with an outside of said jacket, an analog digital converter, a digital computing unit and a signaling device, wherein(a) the digital computing unit comprising a digital delay portion, to delay a temperature value of the liquid cooking medium, measured by the sensor and digitized with the AD converter, said delay portion having at least one thermal time constant to provide a thermally delayed inner temperature value as an output of said delay portion;(b) a switching device is provided to activate the signaling device once a first temperature threshold is reached by said output of said delay portion, for signaling a first cooking state of the at least one cooking item.
