  • Patent number: 4311017
    Abstract: A thermoelectric cooler includes a base unit having an internal heat exchanger located on the upper surface of the base unit and an external heat exchanger disposed in a duct which is located in lower compartment of the base unit. A thermoelectric module transfers heat from the internal heat exchanger to the external heat exchanger. A fan located in the duct blows outside air through the fins of the external heat exchanger. The internal heat exchanger supports a pair of vessels containing liquid to be cooled. An insulated cover unit has a lower peripheral edge which contacts the peripheral lip of the base unit to completely seal the compartment in which the jugs are contained. Each vessel has a spigot which extends through a respective opening in the base unit from the lower portion of that vessel. A pair of stirring mechanisms extend through the top of the cover unit through the lids of the respective vessels to permit stirring of the fluid.
