Abstract
A beverage maker includes a boiler for containing and heating water and a normally opened thermostat having a sensing member for sensing a temperature of the water, wherein the sensing member is located at a certain distance with respect to a water inlet of the boiler. When the water is heated, and the temperature of the water exceeds a set point of the thermostat, the thermostat closes. As a result, a pumping action is started, where hot water is forced to flow out of the boiler, and where cold water is forced to flow into the boiler. When a front of the cold water reaches the sensing member of the thermostat, the thermostat is triggered to open again, and the pumping action is terminated. By means of the thermostat, the quantity of hot water that is used for the purpose of making a beverage is accurately controlled.
