A cleaning apparatus for cleaning articles to be cleaned includes at least one cleaning chamber; at least one conveying device configured to convey the articles to be cleaned in a conveying direction through the cleaning chamber, the at least one conveying device comprising a plurality of tracks arranged side by side; at least one nozzle system configured to act upon the articles to be cleaned with at least one cleaning fluid; at least one sensor configured to detect a loading of the conveying device with articles to be cleaned; and at least one control means programmed to select at least one operating mode of the cleaning apparatus corresponding to the loading of the conveying device detected by the sensor, and to propose the selected operating mode to a user of the cleaning apparatus by providing a visual indicator on one or several tracks of the conveying device.

A conveyor dishwasher includes at least one wash zone and at least one final rinse zone, wherein the at least one wash zone is designed to spray wash liquid, wherein the wash liquid is, at least proportionally, liquid which has already been used for final rinsing in the at least one final rinse zone and to which a wash chemical is added in a metered manner or is fresh water to which a wash chemical is added in a metered manner, wherein the conveyor dishwasher has a metering pump for adding the wash chemical in a metered manner to the liquid to be sprayed in the at least one wash zone, and wherein a controller is associated with the conveyor dishwasher in order to actuate the metering pump and a wash pump or final rinse pump of the dishwasher.

A batch dishwasher (1) has a treatment chamber (2) with at least one wash system which is designed as a recirculation system, wherein the treatment chamber (2) has at least two treatment zones (6, 7) in which washware can be treated at the same time but independently of one another, in particular independently of one another in respect of action time, wash and/or rinse mechanics, and/or independently in respect of the selected treatment program. The at least two treatment zones (6, 7) are each realized in such a way that at least one dish rack (5) can be inserted and removed, and wherein the dishwasher (1) has a mechanism for retracting or extending a dish rack (5) into at least one and, respectively, out of at least one of the at least two treatment zones (6, 7) as required.

A method for cleaning items to be cleaned is disclosed. A cleaning device is used that has at least one cleaning chamber and at least one applicator for applying at least one cleaning fluid to the items to be cleaned in the cleaning chamber. A desired hygiene value is prespecified. The method further includes time-resolved recording of at least two influencing variables which influence hygienization of the items to be cleaned. Hygiene share values are determined from the influencing variables using a prespecified relationship between each influencing variable and the respective hygiene value share of said influencing variable. An expected actual hygiene value at the end of the cleaning from the hygiene value shares is ascertained and compared with the desired hygiene value. At least one of the influencing variables is changed based on the comparison. An inventive cleaning device is also disclosed.

A box-type dishwasher, wherein the dishwasher has a fresh-water connection with a feed valve, wherein a water-treatment system with a reverse-osmosis device is provided downstream of the feed valve in order to treat, in particular as required, as least some of the fresh water fed to the dishwasher via the fresh-water connection, wherein a backflow preventer is provided between the feed valve and the reverse-osmosis device in order to prevent water from flowing back from the dishwasher into a fresh-water-supply installation which is, or can be, flow- connected to the fresh-water connection.

A dishwashing machine is used for pre-rinse operation of soiled dishes. A cavity is configured and arranged to contain the soiled dishes. A nozzle is proximate the cavity and is in fluid communication with the cavity. An accumulator pan accumulates wash and rinse water including cleaning chemicals used in a previous cycle of the dishwashing machine. A fluid passageway interconnects the nozzle and the accumulator pan. A pump directs the accumulated wash and rinse water from the accumulator pan to the nozzle via the fluid passageway for pre-rinse operation of the soiled dishes in the cavity, and the nozzle directs the accumulated wash and rinse water into the cavity with the soiled dishes to assist in removing soil from the soiled dishes prior to a wash cycle of the dishwashing machine. The wash cycle utilizes fresh wash water.

A warewash machine for washing wares includes a chamber for receiving wares, the chamber having at least one wash zone with an associated spray system for spraying liquid onto wares passing therethrough, wherein a downstream drying zone includes a blower for blowing air onto wares passing therethrough. The blower includes an ambient intake operatively connected to an ambient air flow path, a machine intake operatively connected to an internal machine air flow path and an exhaust intake operatively connected to a machine exhaust air flow path.

The present disclosure relates to a dishmachine that includes one or more features directed to water, energy or material savings. The disclosed dishmachines are still capable of meeting the soil demands of the articles to be cleaned.

A method for calibrating a cleaning device that has at least one sensor for detecting at least one state variable, including carrying out a calibration measurement, establishing an electronic connection between the calibration sensor and a controller of the cleaning device, and electronically transmitting the reference value to the controller; and comparing the reference value with at least one measurement value of the sensor of the cleaning device and adjusting at least one correction function in accordance with the comparison. At least one state variable is detected and at least one reference value is determined by means of at least one calibration sensor independently of the sensor of the cleaning device. Future measurement values of the sensor of the cleaning device are automatically corrected using the correction function.

The present disclosure is directed to an apparatus for rinsing and disinfecting utensils, on demand, with a controller operating the components that deliver a pro-determined volume or timed flow of water, and exposure time of sanitizer(s) to the intended objects. The spray embodiment has high performance conical spray nozzle(s) controlled by a controller that reduces water usage and that may vary depending on the viscosity of the material to be eliminated. The recirculating embodiment has a recirculating water system, with a controller operating the components that recirculate water throughout the system until the turbidity exceeds a chosen threshold, and displace with fresh water until the turbidity returns to a lower threshold. The water resumes recirculation until it again exceeds the chose turbidity threshold and the water in the system is again displaced by fresh water. Both spray and recirculating embodiments can contain multiple rinse stations.
