  • Patent number: 10513425
    Abstract: A self-contained, universal portable beverage condition status indicator (10) has relatively large and easily visible top light dome (30) that is selectively lighted to provide an indication as to when a beverage dispenser (12) to which it is mounted is empty of beverage. Mounting is performed without any tools or alteration to the dispenser by simply inserting an elongate sensor probe assembly (50) through an inlet (22) in the top of the dispenser (12) and down to a location adjacent the bottom (16) of the hollow body (14) of the dispenser. Tooless removal is accomplished by simply slidably lifting the indicator (10) upwardly and outwardly from the dispenser (12) until it is clear. It may then be used with a newly filled different dispenser (12). The sensor probe assembly remains functional even though lower portion may be removed. Score lines (64, 70, 65, 59, etc.

  • Patent number: 10334982
    Abstract: Beverage brewer (10) with a control system (FIGS. 5, 6) has a brew basket (22) with a central axis (38), a bottom with an offset drain hole (41) radially, outwardly spaced from the central axis (38) for passing the hot beverage or beverage concentrate to a container (34, 36) and a position detectable element(52). A circular collar (24) mounts the brew basket (22) to the housing (12, 18) in at least two different angular positions (FIG. 3) in which the drain hole (41) is respectively located in at least two different positions outwardly spaced from the central axis (38) to pass brewed beverage to the container (34, 36) when in two different positions (FIG. 1). A sensor (56) detects the angular positions of the brew basket (22, and a controller (66, FIG. 6) responds to the sensor (56) to enable only preselected functions of associated with the sensed angular position.

  • Patent number: 9532682
    Abstract: A grinder (30) has a toolessly attached ingredient hopper assembly (50) overlying a toolessly attached fixed grinding burr (134) defining the top of a grind chamber (158) within which is received a mating rotary grinding burr (150) that is slidably mounted to a rotary drive motor (154) for adjustment relative to the fixed grinding burr (134). Adjustment is achieved automatically by control of a stepper motor (168) that pushes on the end of an elongate control shaft (393) passing through a hollow rotary drive axle (392) and carrying the rotary grinding burr (150) at an opposite end. In a similar embodiment (FIG. 23), the non-rotary burr (314) is adjusted by movement of a control shaft (393) contained within a hollow motor axle (392). In other embodiments (FIGS. 17-22), a movable axle (304) of a movable rotor motor (300) and attached to the rotary burr (312) is moved to make the adjustments.

  • Patent number: 8225708
    Abstract: A beverage brewer (10) with a temperature selectable dispense system having an on-demand hot water heating chamber assembly (30) with a hot water chamber body (86) having a volume substantially less than the volume of beverage brewed during a single brew cycle, a heating element (98) to quickly and substantially alter the water temperature in the chamber body during a single brew cycle and a microprocessor controller (38) for controlling the heating element in response to temperature sensors (40, 42). The controller (38) controls the brewer (10) to brew different types of beverages, with dispense water at different preselected temperatures in response to a manually actuatable switch (72, 74, 76 and 78). The temperature of the dispense water may also be changed from a hotter temperature at the beginning of a brew cycle to a lower temperature during an end portion of the same brew cycle.

  • Patent number: 7631593
    Abstract: A hot beverage brewer (20) with an auto-directive brewer controller (22) that controls enabling and revealing of a plurality of hidden, or phantom, switches (39, 40, 42, 48, 50, 52, 54, 56, 58 and 60). Signals from disabled switches are ignored by a microcomputer (24), and the operator is directed to only the hidden switches that are enabled by selectively revealing them with individually associated backlights (39?, 40?, 42?, 48?, 50?, 54?, 56?, 58?, and 60?). When the backlights are energized the location of the hidden switches is revealed by the light passing through a dark, but semi-translucent, flexible, plastic control panel that overlies the hidden switches and their associated backlights. Different modes of normal operation may be preselected during a program mode (FIG.

  • Patent number: 7506576
    Abstract: A beverage brewer (10) with a controller (14) that automatically disables selected brewer functions unless enabled by an enablement code that enables use that is only sufficient to brew a preselected quantity of beverage by mixing the brew ingredient (18) with water has a reader (54, 56, 58, 56, 59, 62) for communicating with and reading the enablement code (86) from a smart card, card with magnetic strip or other data carrying medium (FIGS. 4 and 5). The enablement card when used by a delivery employee has codes for multiple customers, etc. that is used by the delivery employee to enable the brewers to brew the brew ingredient that is being delivered but no more to avoid brewing of ingredient not provided by the distributor of the brew ingredient. Alternatively, one card (52) is used for each location or each brewer and may only be used with the location or brewer that is indicated.

  • Patent number: 7279190
    Abstract: A brewing control method for use with beverage brewing system (10) uses a controller (52) responsive to a comparison of preselected values of total brew water and total diluent water stored in a program memory (62) and to actual quantities measured by one of two flow meter (36, 36?) to control operation of a brew valve (46) passing water to a hot water tank (14) and a diluent valve (50) for passing water directly to a mixing chamber (28). the controller also responds to a level sensor (20) to control the brew valve (46) to keep the hot water tank filled with water. The preselected amounts of diluent and extract are changed for different brewing conditions to obtain different total quantities of beverage or different ratios of hot brew water passed through the brew basket (24) to cold diluent water passed directly to the mixing chamber, or serving urn (28).

  • Publication number: 20040255787
    Abstract: A self-heating beverage dispenser assembly (10) with an insulated hollow body (18) with an interior space (16) for receipt of hot beverage (14) at an initial beverage temperature is provided with a beverage submersible passive heating element (12) submersed in the beverage and having a body with an interior core (48) made of heat retentive material, such a phase change material or ceramic material or the like, and surrounded by a protective outer shell (46) made of material substantially impervious to contact with hot beverage (14). The core (48) is preheated to an initial internal temperature significantly greater than the initial beverage temperature to transfer heat from the core (48) to the beverage (13) within the container, said self-contained passive heating element being contained within the interior of the hollow body. A passive heating unit energizer (44) selectively heats the passive heating unit (12) to the desired initial internal temperature.

  • Patent number: 6820771
    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.
