Abstract
A refrigerated liquid dispenser is disclosed. The dispenser has a pump configured for being in fluid communication with a source of a liquid product; a dispensing faucet configured for being in fluid communication with the pump, the dispensing faucet including a cold maintenance device located near the distal end of the dispensing faucet and an insulator device disposed adjacent to the cold maintenance device. The cold maintenance device has a distal end that projects beyond a lower surface of the insulator device. The dispenser also includes a dispensing tower for enclosing the dispensing faucet; and an auxiliary cooling circuit configured to direct cool airflow toward the dispensing faucet, the auxiliary cooling circuit having a passageway that is at least partially located within the dispensing tower and the passageway is configured to deliver cool airflow through the passageway onto the dispensing faucet, to shield the dispensing faucet from ambient temperature, thereby maintaining the dispensing faucet and the passageway at a cool temperature to avoid contamination of the liquid. The dispenser also includes a controller operatively coupled with the pump and the dispensing fauc…
