Abstract: A kitchen appliance, such as a mixer, has a housing (1) which has on its upper portion an annular seat (2) for reception of a removable bowl (3), and which encloses a motor (4) whose output shaft (5) projects from the seat. The bowl (3) has a removable bottom (6) constituted by a base of shape complementary to the seat (2) and whose central region bears a rotatable tool (7) integral with a shaft (7') traversing the base and adapted to couple with the output shaft (5) of the motor when the base is correctly mounted on the seat. The base (6) comprises at least one detent (16) which is movably mounted through the wall (12) of the base between a retracted position in which it permits positioning of the base on its seat (2) and thus the coupling of the tool (7) with the shaft (5) of the motor (4) and which position is reached when the bowl (3) is correctly secured on the base, and a projecting position in which it extends laterally of the base.
