The device comprises a basin-like container in which partitioning baffles define a plurality of cavities or moulds open at the top, intended to hold a respective quantity of water put into them by means of a solenoid valve, for the formation of corresponding ice cubes. An ejection device includes an electric motor device to which a rotatable shaft is coupled, from which stretch a plurality of ejector elements capable of provoking the expulsion of the ice cubes formed in said cavities or moulds as an effect of the rotation of the shaft.Control devices are associated with the motor device and with the solenoid valve, and comprise two cams operatively driven in rotation by the motor at different speeds. These cams have respective enabling and control profiles engaged operatively by the same feeler that cooperates with an electric switch in such a way as to define, in the operating cycle of the device, at least one time interval of predetermined duration for the opening of said water feed solenoid valve.
