Abstract: A method and apparatus for cleaning washware, in particular dishes, is provided. In the process, the washware is subjected to at least one wash process in which adhering dirt is at least largely removed. The washware is then subjected to a final-washing process which has at least two substeps. The washware is acted on by a first rinse liquid in a first substep, with the first rinse liquid containing a disinfectant. The washware is acted on by a second rinse liquid in a subsequent second substep, with the second rinse liquid comprising at least one permeate which is produced by reverse osmosis.

Abstract: A cleaning apparatus for cleaning articles is proposed. The cleaning apparatus comprises at least one cleaning chamber for receiving the articles. The cleaning apparatus comprises, in the cleaning chamber, at least one fluid source for subjecting the articles to the action of at least one cleaning fluid. The cleaning apparatus furthermore comprises at least one plasma source, which is designed to ignite at least one plasma in at least one gas and to generate at least one reactive gas. The cleaning apparatus is designed to bring the reactive gas into contact with the articles, at least in part.

Abstract: A heat recovery device is provided for recovering thermal energy from a fluid medium, in particular for use in a waste-water system of a dishwasher. The heat recovery device comprises at least one heat exchanger with at least one heat exchanger surface. The heat recovery device further comprises at least one heating device, which is thermally coupled to the heat exchanger surface, and also at least one controller. The controller is designed to carry out a self-cleaning process for the heat exchanger, with the heat exchanger surface being briefly heated by means of the heating device during the self-cleaning process.

Abstract: A cleaning machine, in particular a batch dishwasher, comprising an individual cleaning chamber in which the items to be cleaned are accommodated, a pump which circulates washing liquid within the cleaning chamber, and a further pump which delivers fresh water, and also a boiler which stores and heats fresh water, wherein the boiler has an associated heat exchanger by means of which heat is indirectly or directly transferred from waste water which is stored in a reservoir to the fresh water which is stored in the boiler.

Abstract: A water treatment device is provided, which has a reverse osmosis device with a raw water supply line, with a pure water discharge line and with a concentrate outflow. The raw water supply line is connected to a mixing device which is designed to set the mixing temperature of the raw water delivered to the reverse osmosis device. The mixing device has a hot water inflow and a cold water inflow.

Abstract: A cleaning appliance for cleaning of cleaning stock is provided, which is set up in order to act with at least one cleaning fluid upon the cleaning stock in at least one cleaning chamber. The cleaning appliance has at least one fluid tank for storing the cleaning fluid. Furthermore, the cleaning appliance has a suction-extraction device for the suction-extraction of moist air from the cleaning chamber and also has at least one heat recovery device. The heat recovery device is set up in order to extract heat from the moist air. The heat recovery device has at least one Peltier element, which has a heat-absorption side and a waste-heat side. The waste-heat side is in thermal contact with a fluid heating device. The fluid heating device is, in turn, in contact with a first cooling fluid and is set up in order to heat this first cooling fluid. The cleaning appliance is set up, furthermore, in order to use the first cooling fluid for a cleaning process.
