Abstract: The present invention provides a system and method for enhancing the carbonation efficiency of an ice-chilled beverage dispenser. The system includes a beverage dispenser having an ice bin, a pre-chill coil proximate a portion of a store of ice in the ice bin; and an under-counter assembly having a carbonator in fluid flow communication with the pre-chill coil, and a pump for pumping water through said system. Water flows through the pre-chill coil prior to flowing through the carbonator. The present invention provides various methods of converting existing ice-chilled beverage dispensers including installing a pre-chill coil proximate to a store of ice in the ice bin so that water flows through the pre-chill coil before it flows through the carbonator. Another method includes diverting the flow of water from a water chill coil to the carbonator, instead of a plain water valve to which fluid originally flowed from the water chill coil.

Abstract: A system for transporting ice pieces or the like from a primary bin to one or more satellite bins is disclosed. A dispenser forms a charge of ice pieces in a precharge chamber, which is then transferred by air assist to a delivery tube. A driver member is provided to engage and move the substantially defined charge of ice pieces to the selected satellite bin. The driver member is propelled by a differential pressure within the tube. This permits the defined charge to be exposed only to the low pressure side and insulated from the high pressure propelling medium to minimize breakage and melting during delivery. Before reaching the satellite bin, the piston is reversed to shuttle back to the home position. The satellite bins are connected in series and delivery of a charge to an intermediate bin is provided by moving a tube section out of alignment with the delivery tube. Lubrication and continuous cleaning is performed by the driver member sweeping minimal residual water from melting ice.

Abstract: A pivoted ice dispensing chute is pushed rearward to lift a door lock, lift a door and contact a microswitch for starting an ice dispensing mechanism. Release of the chute allows the chute to swing forward, opening the microswitch and stopping the ice dispensing mechanism, and allowing the door to drop downward and the lock to drop downward below the door. In its downward position, the door is adjacent the back of the chute to prevent lifting of the door and unwanted movement of ice through the chute. The chute is generally rectangular in planform, with a sloping back, sides and a rounded front. The top of the chute and the bottom of the chute are open. The back of the chute has a rib with a lateral extension which operates the microswitch. The rib lifts the door lock and lifts the door.

Abstract: Out-turned upper edge portions of cabinet walls support a drop-in dispenser on edges of a counter top opening. A trim ring overlies and covers the out-turned edge portions. A tower with valves extends upward from the cabinet, and an anchor extends downward inside the cabinet walls for supporting the tower. A large curved drain pan extends over the trim ring beneath valves on the tower. A drain tube at the back of the drain pan extends straight downward to a drain opening at the bottom of the dispenser. The drain tube is straight and uninterrupted and has a large diameter. A channel extends from the front to the back of the base. An ice storage bin with a cold plate at its bottom is installed in the cabinet, and inlet fittings from the cold plate extend downward and rearward in the channel for ease of connection of liquid lines when the dispenser is tipped on its back, and for preventing damage to the fittings.

Abstract: An ice dispensing apparatus having a storage bin with a paddle wheel which moves the ice from a storage bin to a delivery chute. A straight door is utilized to selectively open and close the delivery chute. A drip pan is provided on the outside of the chute to collect the melt water from the ice, which is in the delivery chute.

Abstract: An ice maker including freeze and harvest controls is disclosed. The evaporator includes a unitary evaporator and ice mold. A compressor and condenser cool the evaporator to freeze ice on the mold in a normal refrigeration cycle and the mold is defrosted by hot gas to harvest ice from the ice mold. The temperature of the ice mold and the liquid line temperature of the condenser are sensed to control the length of time of the ice forming cycle.

Abstract: An ice dispensing bin has an inward and rearward sloped front wall and a downward and forward sloped semi-cylindrical bottom wall. The rear wall and side walls and an upper portion of the front wall are generally vertical. A paddle wheel is positioned in a recess in the sloping front wall. The paddle wheel has a circular plate lying along a central portion of the annular recess. A truncated conical plate converges axially about 10 degrees from the circular plate. Paddles extend radially from the conical plate. Turbine blade-like paddles curve circumferentially and then axially and stop short of the front wall to trap and move ice along the front wall of the recess as the paddle wheel is rotated. A shaft extends through the paddle wheel and rearwardly to a bearing in the rear wall. An angular arm on the shaft breaks ice bridges as the shaft rotates with the paddle wheel.

Abstract: Effective active storage volume of an ice dispenser is increased by an upward and forward sloping bottom wall with a compound curve. A stainless steel helically bent auger rod has a conical shape and closely fits within a trough having a relatively large radius at a rear and a relatively small radius at a front. Larger radius curved lateral areas complete the bottom wall. Ice moves upward toward the front of the bin and then upward at an obtuse angle toward the top of the bin and then tumbles rearward and downward. The rotating auger prevents bridging and continually pushes more ice forward than is dispensed. A helical auger with solid flytes radially extends from a forward portion of the shaft to move ice cubes through the dispensing opening in the front wall at the front end of the trough.

Abstract: Ice is stored for dispensing in a semicylindrical bin. A cone-shaped wire auger is mounted on radial extensions from a sloped axle near the bottom of the bin. A large flyte of the auger pushes ice from the rear of the bin toward smaller flytes near the front of the bin. Distal ends of generally radially extending fingers sweep an opening in the front of a bottom wall. Interchangeable plates with varied size openings control dispensing rate from the bin. The large flyte pushes the ice toward the front where some of the ice drops through the dispensing opening and some of the ice is recirculated upward. Ice clusters near the dispensing opening are broken by the fingers which extend generally radially and slightly rearwardly from the axle on which the conical auger wire is mounted.
