Washing liquid distribution device for a dishwasher

A washing liquid distribution device for a dishwasher, wherein the washing liquid distribution device comprises:

• a holder;
• and
• an impeller,
• wherein the holder is configured to hold the impeller within a washing chamber of a dishwasher,
• wherein the impeller comprises a disc-shaped body provided with a plurality of impeller blades extending from a surface of the disc-shaped body,
• wherein the impeller blades comprise:
• driving blades being angled in a first circumferential direction in relation to a radial direction of the disc-shaped body of the impeller to have a first concave portion facing the first circumferential direction to cause rotation of the impeller in a rotational direction when washing liquid is directed onto the first concave portion of the driving blades,
• wherein the impeller blades further comprise at least one backflow blade being angled in a second circumferential direction in relation to the radial direction of the disc-shaped body of the impeller to have a second concave portion facing the second circumferential direction to counteract the rotation of the impeller in the rotational direction when washing liquid is directed onto the second concave portion of the backflow blades, where the second circumferential direction is opposite to the first circumferential direction,
• wherein the holder comprises a nozzle arranged to direct a stream of washing liquid onto the impeller blades, wherein the stream of washing liquid exits the nozzle in a direction from an inner radius of the disc-shaped body to an outer radius of the disc-shaped body.
