Spray head assembly with interior rises, depressions, and orifices

A spray head assembly for use in a beverage making machine for distributing water over and into a funnel retaining beverage making material, the spray head comprising:

• a mounting having a periphery, a hole, and a connection to a controllable source of liquid from the beverage making machine and a surface for joining to a face portion;
• a face portion having a periphery, an inside surface with a plurality of cylindrical orifices extending there through, the inside surface having a plurality of spaced apart rises and surrounding, connected depressions with each of the orifices being located at a top potion of a corresponding rise and extending through the corresponding rise, the rises and depressions form a generally curved sinusoidal surface extending from the top of a rise, down though surrounding depressions, and up to a neighboring rise for reducing turbulence in the spray head assembly, the depressions being in connected communication so that water can flow among the rises and depressions;
• the mounting sealably connected to the face portion defining a cavity there between so that liquid enter the spray head assembly cavity and only exits though the orifice in the top portion of the corresponding rises;
• and
• structure for connecting the mounting to the outlet to accept liquid into the spray head assembly through the hole and dispense the liquid from the spray head assembly through the orifices and retaining the spray head assembly to substantially direct flow through the orifices, and wherein material and particles from the liquid on the face portion will accumulate in the connected depressions spaced apart from the orifices.

A beverage making machine comprising:

• a liquid source adapted to provide liquid for making a beverage;
• an outlet coupled to the liquid source in a manner for conveying liquid from the liquid source;
• a beverage making material retainer adapted to contain beverage making material;
• a spray head assembly coupled to the outlet for distributing water over and into beverage making material held in the beverage making material retainer, the spray head assembly having
• a mounting having a periphery, a hole, a surface for joining to a face portion, and connection to the outlet enabling flow of liquid from the reservoir to the spray head assembly,
• a face portion having a periphery, a surface with a plurality of cylindrical orifices extending there through, the surface having a plurality of spaced apart rises and surrounding, connected depressions with the orifices being located at a top portion of a corresponding rise and extending through the corresponding rise, the rises and depressions form a generally curved sinusoidal surface extending from the top of a rise, down though surrounding depressions, and up to a neighboring rise for reducing turbulence in the spray head assembly, the depressions being in connected communication so that water can flow among the rises and depressions,
• a holder for coupling the mounting and face portion to define a cavity there between so that liquid enters the spray head assembly cavity through the hole in the mounting and exits the spray head assembly cavity only through the orifice in the top portion of the corresponding rises, and
• structure for connecting the mounting to the outlet to retain the spray head assembly to receive water from the outlet and substantially direct flow through the orifices, and wherein material and particles from the liquid on the face portion will accumulate in the connected depressions spaced apart from the orifices.
