Abstract
A bowl assembly for a base driven appliance, the base driven appliance providing a primary drive coupling for the accessory assembly. The accessory assembly including: a bowl element that defines a reservoir; and a gear-box element having a secondary drive coupling and a secondary driven coupling. The bowl element defines a lower recess that removably receives the gear-box element, such that the primary drive coupling can engage the secondary driven coupling when the bowl assembly is supported by the base driven appliance. The secondary driven coupling is couplable to an accessory element that is operated within the reservoir, and such that the accessory element is operable by rotation of the primary drive coupling.
Claims9
An ice-cream making assembly for use with a base driven appliance, the base driven appliance having a rotatable drive coupling, the ice-cream making assembly comprising:
- a freezer bowl arranged to cool foods therein, the freezer bowl having an upwardly extending central sleeve defining a lower recess, the lower recess having a centrally located aperture, the central sleeve extending upwardly past a fill height;
- a rotatable paddle located within the freezer bowl and having a paddle coupling;
- a gear assembly disposed within the lower recess, the gear assembly including a lower drive coupling sized to engage the drive coupling of the base driven appliance, the gear assembly having an upper drive coupling engaging the paddle coupling through the centrally located aperture when the rotatable paddle is mounted in the freezer bowl, the gear assembly arranged such that the upper drive coupling and the paddle rotate in response to rotation of the lower drive coupling;
- a lid for covering the freezer bowl;
- and
- wherein the freezer bowl has an inner-surface formation and an outer-surface formation, the inner-surface formation comprising a seamless surface that is wrapped over an upper edge of an outer wall of the freezer bowl and the central sleeve, and the inner-surface formation and the outer-surface formation defining a sealed intermediate void region, and
- wherein the ice-cream making assembly is removable from the base with the gear assembly still disposed within the lower recess of the central sleeve of the freezer bowl.
