The horizontal spray shower head may be used to expose the top layer of coffee grinds in the brew basket to an equal amount of hot water within a few seconds of brewing start time. The heated is continually added uniformly over the coffee grinds, and the water filters down evenly through the coffee grinds in the brew basket. By immersing the top layer of coffee grinds uniformly with the hot water, the coffee grinds at each location in the brew basket are all subjected to the same water pressure. In this manner, the horizontal spray shower head effectively eliminates the problem of a cradle being formed in the brew basket. In addition, the maximum number of coffee grinds within the brew basket are given exposure to the heated water. This exposure allows more coffee to be extracted from fewer grinds, thus conserving coffee and avoiding overcooking of the grinds.
In accordance with another aspect of the present invention, the horizontal spray shower head is configured such that water may flow freely through the shower head without backflow pressure. Without the backflow pressure, the heating components for the coffee maker do not have to work as hard to produce an optimal flow rate of heated water. Thus, a coffee maker utilizing the horizontal spray shower head is more efficient. Moreover, without backflow pressure, the flow rate is directly related to the heat output of heater for the coffee maker, and thus may be more effectively controlled. This feature permits a manufacturer to set the flow rate of the coffee maker with certainty by simply selecting the appropriate wattage for a heater.
