Coffee maker having water tank heater control

Abstract:

A coffee maker includes a water tank, a heater, a brew basket, a fluid path between the water tank and the brew basket, a boiler, and a controller in electrical communication with the heater and the boiler. The heater is ON when the volume of water to be brewed into coffee is greater than a first predetermined threshold. The heater heats the water in the water tank to a first water temperature when the volume of water to be brewed into coffee is greater than the first predetermined threshold and less than a second predetermined threshold, which is greater than the first predetermined threshold. The heater heats the water in the water tank to a second water temperature, which is higher than the first water temperature, when the volume of water to be brewed into coffee is greater than the second predetermined threshold.
