  • a conveyor dishwasher comprises a conveyor belt that transports the items to be cleaned or the dishes in the transport direction A through the one or more washing zones and/or treatment zones, with the items to be washed either being placed directly on the conveyor belt or associated holder elements or else the items to be washed can be placed in appropriate containers or baskets, which can then be transported through the one or through the multiple washing zones and/or treatment zones of the dishwasher by means of the conveyor belt or another transport device.
  • the conveyor dishwasher according to the invention also includes a tank for holding a washing liquid.
  • rinsing liquid as used in this application, is to be understood in a broader scope, whereby the rinsing liquid can be water, for example, without specific additives being mixed in, for example for a rinsing zone, but also other liquids and solutions such as water to which a detergent is added.

  • an overflow filter is implemented in a particularly preferred manner, which has the particular advantage that the dirt retained by the filter element or the particles retained by the filter element are passed on and transferred to the spray arms that are further ahead in transport direction A. This also ensures automatic cleaning of the filter element during operation of the transport dishwasher in a particularly advantageous and effective manner.
  • the filter element is cylindrical or truncated, with a longitudinal axis of the cylindrical or truncated cone extending parallel or essentially parallel to a longitudinal axis of the flushing distributor and/or parallel or essentially parallel to the transport direction A.

  • the filter element is preferably arranged in the flushing distributor in such a way that one end is directly adjacent to the inlet opening of the flushing distributor. In particular, this ensures that all flushing liquid that is pumped into the flushing distributor must run through the filter element.
  • a cross-sectional area of the filter element in its rear area in transport direction A, ie in an area facing the inlet opening of the flushing distributor, is preferably so large that it completely covers a cross-sectional area of the inlet opening of the flushing distributor.

  • the filter element is preferably an edge filter, the edge filter preferably having a longitudinal axis which extends parallel or essentially parallel to the longitudinal axis of the flushing distributor and/or parallel or essentially parallel to the transport direction A.
  • An edge filter is particularly advantageous for the essentially linear flows present in the flushing distributor, because a linear or laminar flow can be maintained to a large extent, turbulence can be largely avoided or reduced, so that in particular a pressure loss through the filter element is avoided or can be kept to a small extent.
  • the filter element designed as an edge filter is preferably tubular, preferably also tapering, or essentially tubular, for example also cylindrical, in particular and preferably primarily frustoconical, and has a plurality of gaps over its circumference, which extend in the longitudinal direction of the filter element.

  • This positioning element is particularly preferably arranged in a front region of the filter element in the transport direction, with the positioning element being particularly preferably attached to one end of the filter element that is furthest away from the inlet opening of the flushing distributor. This ensures that the filter element is positioned securely within the flushing distributor.
  • this positioning element is arranged in an area between the filter element and the walls of the flushing distributor, i.e. preferably in a radially outer area of the flushing distributor, and is designed in such a way that a flushing liquid that is already in an area of the flushing distributor that is in Transport direction A is in front of the positioning element, cannot flow back through the positioning element into an area which is behind the positioning element in the transport direction A and between the filter element and the walls of the flushing distributor.
  • this prevents particles that have already passed through the filter element from entering an area in which the last or rearmost connection opening in transport direction A is located, so that this prevents particles from being transported via the flushing arm at the rear in transport direction A or alternatively via the rinsing arms located at the rear in the transport direction A, in particular the last or the last two rinsing arms located at the rear in the transport direction A become.
  • This ensures in particular that the rinsing liquid, which is discharged via the rinsing arm located at the rear in the transport direction, is kept particularly free of dirt and dirt particles.
