Abstract

The invention relates to a conveyor dishwasher having at least one washing zone ( 6, 7 ), at least one rinsing zone ( 8, 9 ) and a heat-recovery device ( 13 ) with a suction-extraction means. The dishwasher also comprises a drying zone ( 11 ). Openings ( 17, 18, 19, 20, 21 ) are provided for the suction extraction of air from the dishwasher. The overall quantity of the exhaust-airstream ( 24 ) can be varied by means of closing elements ( 25, 26, 27, 28 ), in dependence on the operating state of the dishwasher, by virtue of the openings ( 17, 18, 19, 20, 21 ) being completely or partially closed or released.
