An automatic electric maker for coffee or the like, having user selectable AUTO, BREW, WARM or OFF modes. The temperature of the WARM mode is selectable by applying partial power to the heating element. Full power can be triggered using a phase controlled triggerable semiconductor. Monitoring devices measure temperature and time to control the operator of the apparatus and to detect malfunction. A temperature comparator is provided to determine if the water conduit should be cleaned and to determine if the BREW state of the machine should be converted to...
Apparatus for heating water for infusing coffee or the like, said apparatus comprising: heating means supplied by an A.C. power source; power control means for connecting said A.C. power source to said heating means; high power means for causing said power control means to apply full A.C. power to said heating means when a high power is required for the operation of said apparatus; low power means for causing said power control means to apply a portion of subsequent AC cycles to said heating means when a lower power is required, said low power means comp...
