Patent ID: 7875122

Claim:
A method of operating an industrial dishwasher in the form of a batch dishwasher in which a washing phase, a final rinse phase and a drying phase can be implemented; wherein, during the drying phase, program control automatically provides for a main blower to blow atmospheric first ambient air through an air inlet into a treatment chamber, and over wash ware located therein, and then through an air outlet out of the treatment chamber and from the air outlet, through a drying channel, to a blowing-out opening out of the dishwasher, and wherein, during the drying phase, program control automatically provides for an additional blower to blow atmospheric second ambient air directly into the drying channel and, through the drying channel, to the blowing-out opening; and wherein, during at least one operating state other than the drying phase, program control automatically provides for second ambient air to be blown by the additional blower directly into the drying channel and through the drying channel and out through the blowing-out opening, while the dishwasher is switched on but the main blower is switched off, and wherein when a wash tank of the dishwasher has been filled with wash liquid, either filled for the first time or subsequently filled again, the additional blower is switched on, and blows second ambient air into the drying channel and through the drying channel and then out through the blowing-out opening, provided a door of the treatment chamber is not opened following completion of the filling operation, where the main blower remains switched off both during the filling operation and during operation of the additional blower.
