Embodiment Construction

[0038] figure 1 and figure 2 Two variants of the fluid system of the cold beverage dispenser according to the invention are shown. The dispenser comprises a beverage cooling reservoir 1 for receiving beverage introduced through an inlet 12 . The reservoir 1 is equipped with a thermoelectric device 2 for cooling (also called a Peltier cooling device). A thermoelectric device 2 is secured to the side of the reservoir for transferring heat from beverage stored in the reservoir to the thermoelectric device. The reservoir 1 includes a temperature sensor 10 to control the temperature of the beverage. The sensor 10 is preferably positioned so as to detect the temperature away from the side 11 of the reservoir in contact with the thermoelectric device, preferably above the side 11 remote from the reservoir in contact with the thermoelectric device. Any type of temperature sensor can be used, such as a negative temperature coefficient thermistor (NTC).

Abstract

The invention concerns a chilled beverage dispenser comprising : - a beverage cooling reservoir (1) comprising a thermo-electric device (2) and a temperature sensor (10), - a beverage supply (3), - a pump (4) for pumping the beverage from the beverage supply to the beverage cooling reservoir, - a line (5) for dispensing chilled beverage from the outlet (9) of the beverage cooling reservoir, said line comprising a dispense valve (51), wherein the dispenser comprises a beverage recirculation line (6) for recirculating the beverage from the beverage cooling reservoir outlet (9) through the pump (4) back to the beverage cooling reservoir (1).

Description

technical field [0001] The present invention relates to a beverage dispenser configured for serving cold beverages. Background technique [0002] Beverage dispensers that serve cold beverages cool beverages or dilutions from ambient to cryogenic temperatures by establishing heat exchange between the beverage or dilution and a cooling source. Cold sources commonly used now include refrigerators using the principle of refrigerant gas compression and thermoelectric cooling. The advantages of thermoelectric cooling are: small module size, less operating noise and low cost as well as environmental protection. However, thermoelectric cooling has lower cooling efficiency and capacity. [0003] The present invention relates to thermoelectric cooling implemented in a cold beverage dispensing machine comprising a beverage cooling reservoir into which beverage is introduced. A portion of the beverage cooling reservoir is in contact with the thermoelectric cooling assembly, and heat ...
