Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
147 words
IN A THERMOELECTRIC REFRIGERATOR HAVING A FREEZER COMPARTMENT AND A COOLER COMPARTMENT THERMALLY ISOLATED FROM THE FREEZER COMPARTMENT, THE COMBINATION OF A POWER SUPPLY FOR RECEIVING ALTERNATING ELECTRICAL ENERGY AND PROVIDING UNIDIRECTIONAL ELECTRICAL ENERGY, INCLUDING SWITCHING MEANS EFFECTIVE IN A FIRST POSITION TO PROVIDE UNIDIRECTIONAL ELECTRICAL ENERGY AT A FIRST LEVEL AND EFFECTIVE IN A SECOND POSITION TO PROVIDE UNIDIRECTIONAL ELECTRICAL ENERGY AT A SECOND LEVEL, A FIRST THERMOELECTRIC ASSEMBLY POSITIONED TO REMOVE HEAT FROM SAID FREEZER COMPARTMENT AND CONSTRUCTED TO EXHIBIT A PEAK EFFICIENCY AT AN ENERGY LEVEL INTERMEDIATE SAID FIRST AND SECOND LEVELS. A SECOND THERMOELECTRIC ASSEMBLY POSITIONED TO REMOVE HEAT FROM SAID COOLER COMPARTMENT, AND ELECTRICAL CIRCUIT MEANS FOR PASSING THE UNIDIRECTIONAL ELECTRICAL ENERGY FROM THE POWER SUPPLY THROUGH SAID FIRST AND SECOND THERMOELECTRIC ASSEMBLIES IN SERIES, SO THAT ELECTRICAL ENERGY AT THE SAME LEVEL IS ALWAYS APPLIED TO BOTH OF SAID THERMOELECTRIC ASSEMBLIES.
