Abstract
An ice cream machine for household use employs semiconductor refrigeration to produce an efficient, compact and non-polluting appliance. The ice cream machine includes a refrigeration plate, a heat radiator, a cold container, a motor and a stirring shaft. The refrigeration plate includes a plurality of P-N junction semiconductor refrigerators. The ice cream maker includes a power supply to provide 12VDC power to the semiconductor refrigerators. A thermal guiding device conducts heat from the cold container to the refrigeration plate.
