The rinsing chamber (19) houses at least one washing arm (3) comprising a plurality of spray nozzles (4). A waste water line (8), into which the waste water is pumped, extends from the rinsing chamber (19). Waste air is removed from the rinsing chamber (19) via a waste air line (10) into the waste water line (8), wherein the rinsing chamber (19) is limited by at least one wall (32, 34), which stores a heat exchanger fluid (40) or through which heat exchanger fluid (40) flows.
