  • Patent number: 6576282
    Abstract: A beverage brewer (20) with a programmable dispenser cycle dispenser valve controller (36) for controlling a dispenser valve (34) to intermittently open and close during a plurality of control periods of an intermittent dispense period (88) to selectively control the quantity of hot water that is dispensed without changing the overall duration of the dispense period (88). Each of the control periods (CP1-CP20) has a duty portion during which the dispenser valve is open that is selectively varied to brew either greater or lesser amounts of beverage without varying the overall dispense period (88). Uniform contact of the hot water with the beverage ingredient (70) is enhanced by a uniform ingredient holder (24) that holds the ingredient in a tubular configuration beneath a uniform flow dispenser head (38) that pulses the top of the tubular configuration with a uniform spray.

  • Patent number: 6543335
    Abstract: A twin brewer system (30) with a pair of brewers (30A, 30B) each with a controller (158) for controlling the application of electrical power to a hot water heater, disables the application of electrical power to the heater (154) of one brewer (30A, 30B) in response to actuation of a start brew switch of the one brewer (30A, 30B) while electrical power is being applied to the heater (154) of the other brewer (30A, 30B). The controllers also respond to a hot water quantity sensor (164, 168) and a responsive delay circuit for disabling dispensing of hot water in response to actuation of the brew start switch (50) until a sufficient quantity of hot water is in a hot water dispenser tank (152) needed for the brew cycle. Indication lamps indicate when the brew cycle is being delayed and when brewing is not being performed. Actuation of a single emergency stop switch (138) stops hot water dispensing of both brewers (30A, 30B).

  • Publication number: 20030034357
    Abstract: An insulated beverage dispenser (10) with an outer housing (24) having reinforcing cavities (86) and reinforcing ribs (88) on a canted surface (92) of a top closure (78) to resist distortion that is fitted over an integrally formed inner liner (48) in spaced relationship to provide a gap (52) that is evacuated to approximately 8% of standard atmospheric pressure. The bottom closure (62) of the inner liner (48) is symmetrically tilted downwardly across the center to a center-offset drain opening (76) to reduce the lateral extent (137) of a dispense tube (136) to reduce the quantity of beverage contained within the dispense tube (136) and subject to heat loss between the drain opening (76) to and a faucet (20). The dispense tube (136) is protectively contained within a hollow bottom section (25) for purposes of insulation and is also wrapped in foam insulation (139) for further insulation.

  • Patent number: 6499628
    Abstract: An insulating, serving urn assembly(10) with an extra closure assembly(40) releasably mounted within the neck(28) of an urn body(22) for reducing the loss of heat from within the urn during brewing of beverage into the urn assembly(10) by passing the beverage into the urn body through a relatively small drain opening(73) of a brew guide(46) mounted to an extra closure member(42) that closes off the inner opening(26) of the urn. After,brewing is complete but before serving from the urn assembly(10), the beverage is additionally insulated by a lid(36) that fits over the outer opening(24) of the urn assembly(10) and a brew guide closure(76) that is mounted to the underside(36B) of the lid(36). During service a relatively small, extra closure service opening (50) located adjacent to a spout (34) in the extra closure member(42) is opened with movement of a rotatably mounted door(44) to an open position to enable pouring out of the beverage while still covering most of the inner opening(26).

  • Publication number: 20020083840
    Abstract: A self-heating urn (10) is provided with a warmer packs (18) which are rapidly heated during the brewing process and then gradually release their heat to the brewed beverage within the urn after it is removed from the brewing location to a serving location at which electrical powered for heating is not available. The warmer pack (18) are formed of ceramic materials, high density liquids, PCM's or the like which are capable of being rapidly heated during the brewing process but then gradually release their heat to the beverage in the urn. Alternatively, the warmer packs (18) are removably mounted within a compartment (68) within the self-heating urn (10) and are heated apart from the brewing process and then inserted into the self-heating urn (10) when it is moved to a serving location.

  • Patent number: 6148717
    Abstract: A beverage brewer (20) with a dispenser valve (34) for passing brewing liquid from a supply (30) under control by a programmable dispenser cycle dispenser valve controller (36) to intermittently pass the liquid to a uniform flow dispenser head (38) during preselected duty portions (92) of a plurality of control periods (CP1-CP20, FIG. 5B) in order to independently control the total quantity dispensed and the duration of the dispense period (88). The uniform flow dispenser head (38) has a closed body with a perforated bottom (64) that is intermittently filled with brewing liquid during the duty portion selected for each of the control periods to provide a uniform vertical spray across an open top of a uniform ingredient holder (24) within which is held a cylindrically shaped layer of beverage ingredient (70) in order to achieve uniform contact of the brewing liquid with all the beverage ingredient.
