Patent number: 8491723Abstract: A method for an automated self-cleaning of a continuous dishwasher for items to be cleaned with at least one rinsing zone, at least one clear rinsing zone and also a transporter. Items to be cleaned are conveyed in the direction of transportation via the transporter. The continuous dishwasher comprises at least one fine filter with a back-rinser on at least one storage tank and also at least one device for emptying each of the storage tanks. The continuous dishwasher automatically carries out a self-cleaning cycle in which cleaning liquid located in each of the storage tanks is used several times in succession in the various zones for cleaning thereof. The cleaning liquid is circulated by means of circulating pumps in the respective storage tanks and supplied to spraying systems, which are already present in the respective zones, or to separate nozzles or nozzle heads for wetting the inner side of the faces delimiting the respective zone.Type: GrantFiled: July 26, 2010Date of Patent: July 23, 2013Assignee: Meiko Maschinenbau GmbH & Co.

Publication number: 20100132740Abstract: Particularly in hospitals, care homes or similar institutions, it is necessary to have a safely handled and reliable method for the emptying and cleaning of excretion containers, for example urine bottles or bedpans. A method and a system (110) are therefore proposed, by means of which such articles to be rinsed (112) can be treated. In this case, first, in an emptying step (210), the articles to be rinsed (112) are emptied and are rinsed out with a rinsing-out liquid. Subsequently, in a circulation step (212), the articles to be rinsed (112) are washed in circulation. Finally, a rinsing-clear step (214) is carried out, in which the articles to be rinsed (112) are rinsed with a rinsing-clear liquid. Then, in an optional disinfection step (216), preferably a chemical disinfection step (216), the articles to be rinsed (112) are disinfected, and, in an optional drying step (218), the articles to be rinsed (112) are dried by being blown off with heated air.Type: ApplicationFiled: April 4, 2006Publication date: June 3, 2010Inventors: Denis Lehmann, Michael Streb, Marcus Braun, Heinz-Peter Werner
