摘要:
An improved ice dispensing mechanism for an ice hopper is characterized by a door or gate which is moved by a variable force to cover and uncover an opening in the hopper. A lever is pivotally mounted at one end and connected at an opposite end with the door, and a solenoid plunger is coupled through a spring with a medial portion of the lever, such that actuation of the solenoid retracts the plunger to extend the spring in one embodiment, and to compress the spring in another, to exert a variable force on the lever to pivot the lever and open the door. Should the door be stuck closed because of ice pressure, by virtue of the spring minimum retraction forces are initially encountered by the plunger when the solenoid is initially energized and the plunger fully extended. This enables the plunger to move into the solenoid, whereupon increased forces are exerted on the plunger by the solenoid, and therefore on the spring, to free the door. Consequently, full solenoid power may always be developed to open the door.

A control system for an ice dispenser maintains an icemaker thereof continuously operative whenever an ice storage hopper is less than completely full. This is accomplished by continuing to operate the icemaker while momentarily agitating and leveling the mass of ice in the hopper whenever ice builds up around a thermostat therein, and thereafter sensing whether the ice has dropped away from the thermostat. If it has, the icemaker is maintained in operation and the cycle is repeated. If, however, it has not, then the icemaker is turned off until sufficient ice is dispensed from the hopper to again drop the ice level to below the thermostat. In this manner, the number of on-off cycles of the compressor and other components of the icemaker are minimized in maintaining the hopper completely full, which greatly increases their operating life and reliability.
摘要:
The present invention relates to a method and apparatus for determining the size of an object. The method includes the steps of reflecting light from the object, measuring a plurality of adjacent light intensities reflected off an axis of the object, comparing adjacent light intensities, identifying a position where the light intensity markedly changes along the axis by a predetermined amount, and determining the size of the object from the identified position. The method is used to determine the amount of liquid necessary to fill a cup of the height determined. The apparatus for determining the size of an object includes means for reflecting light from the object, means for measuring a plurality of adjacent light intensities reflected off an axis of the object, means for comparing adjacent light intensities, means for identifying a position where the light intensity markedly changes along the axis by a predetermined amount, and means for determining the size of the object from the identified position.
摘要:
An automatic beverage dispenser having a single flavor or a multiflavor automatic beverage dispensing valve (faucet) and including a system for preventing the dispensing of a warm casual drink. The automatic dispenser includes an on-board computer having a timer circuit to purge the warm water in the uncooled portion of the water line between the cooling apparatus and the dispensing valve whenever a drink is requested and no drink has been dispensed for a particular period of time. The warm water is purged or drained out for a period of time needed to purge the warm water from the uncooled portion of the water line. In another embodiment, a temperature sensor is included in the water line and the warm water purging terminates when the temperature falls to a predetermined value.

An automatic beverage dispenser having a multiflavor automatic beverage dispensing valve (faucet) and including means for preventing color and flavor carryover from one drink to the next. The automatic dispenser includes an electronic control system with an on-board computer with a microprocessor which, when a drink vend signal is received by the electronic control system, first checks to determine whether a dark or light colored drink was requested, then checks the last vend to determine if it was a light or dark drink. If the drink ordered was a light drink and the previous drink was a dark drink, then the controller looks to see if the cup dispenser position is occupied. If it is occupied, the flush is delayed until it is free when the soda water will flush to cleanse the nozzle. After flushing, the vend is processed.

An automatic postmix beverage dispenser having a single or multiflavor automatic beverage dispensing valve (faucet) and including means for preventing the dispensing of a warm casual drink. The automatic dispenser includes an on-board computer having a timer circuit to purge the warm water in the uncooled portion of the water line between the cooling means and the automatic beverage dispensing valve whenever a drink is requested and no drink has been dispensed for a particular period of time. The warm water is drained out for a period of time needed to drain the warm water in the uncooled portion of the water line. In another embodiment, a thermometer is used and the water is purged when a drink is requested and the water temperature is above a certain value, and until it is reduced to a desired temperature.
摘要:
An automatic postmix beverage dispensing system including a conveyor, a multiflavor valve, and a stationary flavor indicator adjacent to each cup pick-up station to inform the operator what beverage is in each cup. Each time the conveyor advances the cups one station, the flavor indicator scrolls forward to continue to correctly identify the beverage in each cup. The flavor indicator can also include order indicia identifying the order number of each cup.
