PURPOSE:To feed hot coffee and ice coffee at the same time, by providing an operation control circuit driving a coffee extracting means and a hot water feeder and by mixing condensed coffee quantitatively discharged from a coffee storage tank with water. CONSTITUTION:A discharging coil 22 for condensed coffee is driven by the output from a control circuit 24 for only pulse numbers C during the time D to discharge a constant volume of condensed coffee. And at the same time, a water feed valve 16 is driven only for the time D to feed a constant volume of city water to a hot water tank through a feed water pipe. By the water head, the hot water within the hot water tank is fed from a hot water outlet through a feed pipe, and the condensed coffee is mixed with hot water to feed a cup of coffee from the nozzle. When the first switch 5 for discharging hot coffee is pushed with one touch, hot coffee is supplied and also when the second switch 6 for discharging ice coffee is pushed, condensed coffee is supplied for ice coffee with ice. |
