Abstract
A wash arm arrangement (20) for a dishwasher is disclosed. The wash arm arrangement comprises a central arm (21) adapted to be rotatably connected with a first shaft (23) through which liquid under pressure is fed into the central arm during operation. A second shaft (24) is arranged on the central arm to provide liquid to a satellite arm (22) which is rotatably connected with the second shaft. The satellite arm comprises a collimating nozzle (25) with an exit. The collimating nozzle is arranged for providing a collimated jet for distributing liquid to a washing area of the dishwasher. The inventive concept is based on an understanding that by utilizing a collimated liquid jet with sufficient pressure and flow a good cleaning performance is achieved with a reduced water consumption.
