ABSTRACT:
A presser member, into which the container is loaded, is manually depressable against the action of its return spring into pressure-contact engagement of the container with an electric heating plate containing a PTC heating resistor. The depression stroke produces closure of a switch to energize both the PTC resistor and an electromagnet keeping the presser member in its depressed condition. A timer circuit opens the switch at the elapse of a prealably experimentally determined heating time during which the liquid reaches its consumption temperature, whereby heating is terminated and the return spring lifts the pressure member with the container to unloading position. The heating process comprises a fast initial heating period until the PTC resistor temperature reaches a predetermined maximum value, and the consumption temperature of the liquid is reached by intermittently energizing the PTC resistor at short intervals (fraction of a second) in a high-temperature range directly adjacent said maximum value without exceeding the latter.
