Abstract: Centrifugal pump, in particular drain pump for washing machines, comprising a casing (10) that defines a chamber (11) within which an impeller formed by a hub (14) and a disk (15) provided with blades (16) is capable of rotating. The impeller is provided with at least a slit (20) adapted to generate a negative pressure on the rear surface of the disk (15) during the rotation of said impeller. The solution is very simple and rational; it enables a clogging of the impeller, as it may be caused by the presence of foreign matters and bodies in the washing liquor, to be avoided. It also enables axial thrusts, as they occur during the rotation of the impeller, to be compensated for.

Abstract: A dishwashing machine has a single motor pump unit, including a circulating centrifugal pump and a peripheral outflow drain pump mounted on a common shaft of a reversible drive motor to alternately deliver a washing fluid to and drain fluid from the dishwashing machine. The two pumps are connected by openings in their respective pump chambers communicating with an annular chamber between the two pumps. The annular chamber has a vent fluidly connecting the chamber with a washing water circuit of the dishwashing machine. Preferably the annular chamber has an impeller therein mounted on the drive shaft of the motor, forming a further centrifugal pump with the annular chamber.

Abstract: A dishwashing machine includes a recirculating pump having a casing, an inlet communicating with a sump of a washing tub, an outlet communicating with a spray arm located above the sump, and an impeller rotatable within the casing in a recirculating direction during a washing phase of operation of the machine and rotatable in a direction opposite to the recirculating direction during a drain phase of operation of the machine. A recirculating filter is positioned between the spray arm and the sump. To ensure that all water collected in the sump adjacent the inlet of the recirculating pump is discharged during the drain phase of operation of the machine, a conduit has a first end connected to the interior of the casing of the recirculating pump and a second end positioned adjacent the recirculating filter.

Abstract: A pump unit, particularly for use in a dishwasher, includes first and second pumps having respective impellers and a motor drive shaft fixed to the two impellers for alternately rotating the impellers in a first direction, during which only the first pump delivers a liquid, and an opposite second direction during which only the second pump delivers a liquid. The first pump is a peripheral outflow pump, and the second pump is a centrifugal pump the impeller of which includes blades oriented forwardly with respect to the second direction of rotation.
