摘要:
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. 21) electronic level sensing assembly carried by the dispense tube (40) for sensing a plurality of different levels of beverage (36) within the hollow body and electrical leads (170, 172) printed on the dispense tube to pass the sensing signals to a display controller (127). The display, controller and portable power source (123) are protectively contained within a plastic watertight compartment (126) integrally formed with the cover body (24) is vented (FIG. 20) to prevent the accumulation of moisture within the compartment (126).
摘要:
A food processing apparatus (20) such as a coffee brewer having functional elements (45) protectively contained with a housing assembly (43) composed off a wall assembly (44, 448, 44B) having wall panels (58,60,62 and 64) being formed from a single, thin-sheet, metallic work piece (50) that extend between corners (66,68,70 and 72) formed in the work piece by folding the work piece (50) at each of the corners with at least one fold having an angle substantially different from a right angle. After the corners are formed, opposite ends (52,54) of the work piece are aligned in abutting relationship at a location laterally spaced from all the plurality of corners and permanently welded together with a weld joint (56). As a result of bringing together the opposite ends, at least one of the panels is stressed into an arcuate shape and also forms interior corner angles at opposite sides that are substantially different from a right angle. A closure base (48) is attached to the bottom of the wall assembly (44) to close and support the open bottom of the wall assembly (44), and a closure top (46) attached to, supported by and closes the open top of the wall assembly (44).
摘要:
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). A spray plate (38) mounted beneath the umbrella-like member (34) has 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.

A spray plate (38) mounted beneath the umbrella-like member (34) has a downwardly, outwardly tapered top surface with radiating, 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. Mineral encrustation is reduces by making the spray plate (38) of a material, such a polypropylene, that is hydrophobic and has a heat transfer coefficient that is substantially less than that of metal to reduce evaporation of residual water from the surface of the spray plate. Alternatively, the spray plate (38) is coated with PTFE or the like. The spray plate (38) has a surrounding outer edge that varies in radial distance from the core around a periphery of the umbrella-like body to form a plurality of radially extending pedals (80) separated by a plurality of slots (82). Tooless securing means (32, 60) permits relative rotation of the core within the passageway (22) scrape clean the core and passageway of residue. A method provides for retrofitting flat plate spray plate type distribution systems with the spray plate (38) though the use of an adapter (158)
摘要:
An electrical beverage brewer (10) having a controller (26) responsive to a start switch (72) to operate a brew cycle by dispensing hot water from a tank (42) to beverage ingredient within a brew basket (38) through a bent tube (78) mounted to the water tank (42) for rotation about an axis aligned with an external horizontal rotary section (90) of the bent tube (78) between a closed position in which an inlet (80) of a swinging tubular section (79) is in a relatively elevated, closed position and an open position at a lower elevation relative to the closed position. A rotary electromechanical solenoid (96), a pneumatic rotary solenoid (134) or a stepper motor (126) or other like rotary, drive mechanism requiring no positional sensors has a rotary axis aligned with the central axis of rotation of the rotary section (90) and axially linked, inline, with the rotary section (90) to axially drive the rotary section (90) and thereby move the swinging section (79) between the open position and the closed position without applying lateral forces to the rotary section (90).
摘要:
A hot beverage brewer (20) with an L-shaped, segmented, hot water tank (36) having a laterally extending side body (50) to which is mounted a membrane mounted tubular brew valve (38) with a dispense tube (66) and an electromagnet (92,94) selectively energized by a micro-computer controller (28) to attract in successive stages a first stage energy plate (98) and a second stage energy plate (102) attached to the dispense tube (66) to move the tube from a closed position (FIGS. 2 and 3) in which an inlet (72) of the tube is above a preselected level (42) of water in the tank (36) to an open position (FIGS. 4 and 5) in which the inlet (72) is beneath the surface to pass hot water to a spray head (76). In one embodiment, one or more of the energy plates are permanent magnets (138,140) and in other embodiments the plates (98,102) are not permanent magnets and are resistive to being permanently magnetized.
