  • Apparatus for brewing beverages
    Patent number: 6098525
    Abstract: An apparatus for brewing hot beverages, such as coffee, comprising a water reservoir, a heating element for heating water in the water reservoir, an extraction device, an electric pump and a thermostat for the detection of the temperature of the water in the reservoir. The thermostat is connected in series with the heating element and the pump is connected in parallel with the thermostat. After the water has reached the desired temperature the thermostat is closed, which causes the pump to be switched on in order to pump the hot water to the extraction device. During the pumping phase the power of the heating element is virtually cut off.
