Kind Code:
A3
Abstract:
The invention relates to a dishwasher which is designed in the form of a box-type dishwasher or of a conveyor dishwasher (50) and has at least one wash system (51, 52) designed in the form of a recirculation circuit. The wash system (51, 52) has a nozzle system with at least one wash nozzle (13-1, 13-2) for spraying wash liquid onto the wash ware which is to be cleaned, also has a wash tank (14; 14-1, 14-2) for collecting at least some of the sprayed wash liquid, and additionally has a wash pump (11; 11-1, 11-2) by means of which wash liquid collected in the wash tank (14; 14-1, 14-2) is fed to the at least one wash nozzle (13-1, 13-2). There is also a dirt-collecting system (70) which is assigned to the at least one wash system (51, 52) and has at least one tank-covering screen (20; 20-1, 20-2), in order to separate off particles of dirt from the wash liquid which has been sprayed and flowed back into the wash tank (14; 14-1, 14-2) under gravitational force. In order for the particles of dirt which are washed off the wash ware during operation of the dishwasher to be separated effectively from the wash liquid, the dirt-collecting system (70) also has a dirt-collecting region (71) which is arranged in the wash system (51, 52) and is intended for collecting the particles of dirt which have been separated off from the wash liquid with the aid of the tank-covering screen (20; 20-1, 20-2), wherein the dirt-collecting region (71) is open at the top, but closed all the way around the sides, and wherein there is also a dirt- discharging pipe system (72, 73; 72-1, 73-1; 72-2, 73-2) which is connected to the dirt- collecting region (71) and by means of which the particles of dirt collected in the dirt- collecting region (71) are discharged from the wash system (51, 52).
