Abstract: A spray distribution assembly (14) for a hot beverage brewer (10) with a spray head (20) having a generally vertical passageway (22) for receipt of hot water and an umbrella-like member (34) with an underlying spray plate (38) having a downwardly, outwardly tapered top surface with radiating, outwardly, downwardly directed, upwardly facing grooves and an upwardly standing central core (58) snuggly received within the passageway (22) joined to the underside of the top of the umbrella-like member (34) with a plurality of vertical radially, outwardly facing grooves (68) extending from the top to the bottom to form a plurality of peripheral closed channels for passing hot water to upwardly facing grooves (74) of the umbrella-like body. The umbrella-like spray plate assembly may be attached to a cup shaped spray housing (144) in lieu of a flat spray plate (142) by means of a mounting adapter (158).

Abstract: A hot beverage brewer (10) having a hot water dispense system (12), a brew basket assembly (18) for holding ingredient to be mixed with the hot water to make a freshly brewed hot beverage and a controller (16) for controlling the delivery of hot water from the hot water dispenser system to the brew basket (18) with a spray distribution assembly (14) having a spray head (20) having a generally vertical passageway (22) for receipt of hot water and an umbrella-like member (34).

Abstract: An airpot beverage dispenser (10) having a composite dispense tube (40) with an exterior outlet (44) adjacent a top of a hollow body (20) and an interior inlet (110) located adjacent a bottom (16) for passing beverage (36) from adjacent the bottom (16) to the outlet when the interior of the hollow body (20) is pressurized has a brew-through assembly with a cover body (24) for substantially closing the open top (18) except for a centrally located brew-through passageway (95) substantially smaller than the open top (18) and extending between an upwardly facing exterior brew-through inlet (30) and an interior outlet (102) that passes through a central passageway extending through a double-walled bellows (74) or extends past a plurality of bellows (FIG. 16, 114) that are laterally spaced from the passageway has an electronic display (48) for indicating a plurality of levels of the beverage (36) within the hollow body and a resistive (FIGS. 11-14) or capacitive (FIG.

Abstract: A beverage apparatus (10) having a liquid holding member (12,14,16) with an operating apparatus (42) for performing a particular function, such as heating water to make a beverage, is selectively connected through an electronic switching device (36) to a source of electrical power (40) that is mounted to the liquid holding member (12,14, 16) to convey heat away from the electronic switching device (36) and into the liquid. A radiating heat sink with radiating member (45,47) protects the switching device against potential damaging physical contact is also connected to the switching device (36) and radiates heat generated by the device into the atmosphere for additional cooling of the switching device (36).
