ABSTRACT:
The automatic coffee maker has a saddle valve attachment for connecting it to a cold water line via a small plastic water hose, thereby producing an automatic water supply to the coffee maker. The desired number of cups of coffee can be selected and activated using a dial/pushbutton set of controls. A water level indicator on the water reservoir assembly allows the user to automatically refill the automatic coffee maker in accordance with projected demand for coffee. A light indicator provides a visual cue that the automatic water supply valve is activated. An adjustable cup-setting dial and automatic timer allow the user to select the appropriate water level for the number of cups desired. Water can also be poured into the top of the water reservoir assembly for operation when the automatic coffee maker is not connected to the water supply. The unit uses coffee filters that are premeasured and have a self-contained packet of coffee grounds or crystals that allows the consumers to make precisely the number of cups they wish to brew.
