<p>ICE CREAM MAKING MACHINE WITH A PELTIER EFFECT REFRIGERATION UNIT An ice-cream making machine has a container (3) for the ice cream and a motor-driven stirrer (4) located within the container (3), which is cooled by Peltier effect thermo-elements (8) each having a flat side in contact with a wall of the container (3) and an opposite flat side in contact with a heat dissipation member (9). The Peltier effect thermo-elements (8) are located between the bottom wall of the container (3) and the heat dissipation member and the lower surface of the container bottom wall has raised flat surface portions (11) in correspondence with the thermo-elements (89; the heat dissipation member has flat surface zones (9b) in contact: with the thermo elements (8), and the surface area of each of the raised flat surface portions (11) and each of the said flat contact zones (9b) are at least equal to the surface area of each side of each Peltier effect thermo element (8).
