Abstract:
1. Conveyor ware washer including a conveyor mechanism for carrying items along a conveyor path, a supply of cleaning or rinsing liquid and a spray pipe for spraying items to be washed with liquid, the spray pipe including a plurality of nozzles, which are arranged one behind another in a longitudinal direction of the pipe, and an inlet in communication with the supply of cleaning or rinsing liquid, from which the liquid can flow in the longitudinal direction of the pipe to the nozzles, characterized in that, at least in the case of two nozzles one following another in the liquid supply direction, the nozzle located closer to the inlet has a nozzle opening with a larger opening cross section than the nozzle adjacent to it further away from the inlet; the nozzle opening of at least the nozzle located closest to the inlet, has an outlet direction which extends obliquely in a direction opposite to the liquid supply direction seen from the inlet to the nozzles at an angle of inclination, the angle of inclination being defined between the outlet direction of the nozzle opening and a transverse plane which extends at right angles to the liquid supply direction; the nozzle opening of at least two successive nozzles is inclined obliquely in the opposite direction to the liquid supply direction, the angle of inclination of the following nozzle being smaller than the angle of inclination of the preceding nozzle.
