Abstract
An ice-cream maker having a cylindrical container, into which a discoid cold cartridge is insertable, and an electric motor, through a gear unit, drives a shaft located in the container. The shaft includes a scraper and stirrer tool acting at least together with the cold cartridge. The cold cartridge is provided, around its circumference, with a continuous, outwardly projecting edge and the container interior wall is provided, around its circumference, with a corresponding step extending into the inside of the container. A cold cartridge inserted into the ice-cream maker lodges its projecting edge on this step and at least the bottom wall of the cold cartridge is located at a distance from the container wall.
