  • 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.

  • Patent number: 4297850
    Abstract: A thermoelectric front-opening refrigerator suitable for mounting in recreational vehicles includes a shallow external housing enclosing an electric fan unit and an external heat exchanger. A housing extends to a front grill above a front door of the refrigerator so that air drawn into the housing by the fan unit is blown at high velocity through fins of the external heat exchanger and then through an opening in the grill unit and thereby is ejected at high velocity away from the vicinity of the electric refrigerator so that air heated by the external heat exchanger is not recirculated through the thermoelectric refrigerator.
