Abstract: A method is provided for operating a dishwasher (1) in the form of a batch dishwasher, which has a treatment chamber (2) for accommodating washware to be cleaned. Provision is made, during an adsorption phase, for air to be conducted out of the treatment chamber (2) through a sorption unit (41), which contains a reversibly dehydratable dry material, in such a way that the dry material absorbs moisture from the air stream, wherein the air is then returned to the treatment chamber (2). Provision is further made, during a desorption phase, for the dry material of the sorption unit (41) to be heated in such a way that moisture is desorbed from the dry material as steam. During the desorption phase, the sorption unit (41) is subjected to forced ventilation only to such an extent that recondensation of desorbed steam in the sorption unit (41) itself is effectively prevented.

Abstract: A warewasher (1) provided as a box-type warewasher and a method for operating such a warewasher (1) are provided. In accordance with the warewasher and method, during the adsorption phase, air is guided from the treatment chamber (2) of the machine (1) through a drying unit (40) in such a way that moisture from the airflow is absorbed by a dry material, wherein the air is then fed again to the treatment chamber (2). Furthermore, the drying device is arranged above the treatment chamber (2) so as to effectively prevent penetration of splashed water into the drying device (40).

Abstract: The invention relates to a dishwasher in the form of a commercial utensil washer or dishwasher which is designed as a batch dishwasher and is realized as a hood-type dishwasher, wherein the dishwasher has a treatment chamber with at least one wash system which is designed as a recirculation system, wherein the treatment chamber has a first treatment zone and at least one further, second treatment zone, wherein items of washware can be treated independently of one another and at least temporarily at the same time in the first and in the at least one second treatment zone.

Abstract: The invention relates to a commercial dishwasher (1) which is in the form of a batch dishwasher and has a treatment chamber (2) for accommodating washware which is to be cleaned and also has a drying device for drying washware which is accommodated in the treatment chamber (2) as required.
