Definitions

  • the invention relates to a method for cleaning items to be washed, in particular bedpans, urine bottles and / or the like by means of a rinsing device.
  • Flushing devices for rinsing items to be washed in particular bedpans, urine bottles and / or the like are known per se from the prior art as well as methods for cleaning items to be washed, which is why a separate documentary proof at this point is not required.
  • the process is carried out as follows: The rinsing device is loaded with items to be cleaned. It then takes place the actual cleaning process, which can be multi-stage. For example, in a first stage, cold water cleaning may be provided. This is followed by a thermal disinfection by means of superheated steam. After cooling, the cleaned items to be rinsed the rinsing device can be removed again.
  • the purging devices previously known from the prior art have control units that allow a user to select a cleaning program.
  • a plurality of different cleaning or rinsing programs are provided by the rinsing device, from which the operator can select.
  • the rinsing device After manual selection of the cleaning or rinsing program by the user, the rinsing device starts the selected rinse program and there is a corresponding cleaning of the rinses taken up by the rinsing device.
  • the method proposes a method for automated cleaning of items to be washed, in particular bedpans, urine bottles and / or the like by means of a program-controlled flushing, in which a detection of the loading of the flushing performed with items to be washed, one of several predetermined cleaning programs depending on the detected load is selected and started automatically, wherein in the case of an unsuccessful load detection, a preselected cleaning program is started.
  • the invention proposes a method which enables automated cleaning.
  • a user has a plurality of predetermined cleaning programs available.
  • the special feature according to the invention consists in the fact that a washware identification is carried out and a cleaning program is selected and started automatically as a function of the detected washware load. If successful load detection is not performed, cleaning is performed according to a pre-selected cleaning program for this case.
  • the cleaning program is selected. There are preferably a variety of cleaning programs to choose from. One of these is selected as a function of the detected load state and started automatically.
  • a cleaning program preselected for this case is started, which is preferably a standard cleaning program that ensures a sufficient cleaning quality in each case. It is thus ensured in an advantageous manner that a cleaning program is started in any case, even if the load detection remains without result.
  • the method implementation according to the invention is characterized in that, unlike the prior art, it is not dependent on a manual program specification by the user. Rather, the cleaning method according to the invention is automated, with the execution of a cleaning program being carried out fully automatically as a function of previously performed load detection. Manual malfunctions can thus be ruled out, which simplifies the entire process application and makes it safer. The method according to the invention therefore also enables an improved cleaning result.
  • the method implementation according to the invention is less time-consuming and much easier for a user to operate.
  • the resource consumption can be especially of water due to manual misuse.
  • the automatic load detection also makes it possible to detect manual incorrect loadings, for example, those that would lead to a hygienically insufficient cleaning due to misplaced items. By indicating to a user that automatic dishwashing detection is not possible, he is made aware on the device side that there is an improper loading of the flushing device. Otherwise, automatic dishwasher detection would be possible. The user is thus given the opportunity to carry out a new charging of the rinsing device with the aim of a proper and best results rinsing permitting positioning of the items to be cleaned within the rinsing.
  • a user of the rinsing device is made aware of the automatically selected cleaning program. The user therefore knows which cleaning program has been selected.
  • the predetermined cleaning programs have an at least approximately identical starting phase, d. At the beginning of the program sequence, at least approximately identical program steps with at least approximately identical program parameters are carried out in all predetermined cleaning programs.
  • the started cleaning program can be overruled by the user.
  • appropriate operating devices must then be provided.
  • the starting phase can be provided in a particularly advantageous manner, in which there is still no diversification. This procedure is time-optimized, so that no timeout is required for the eventual selection of the program.
  • the user-side override can be disabled.
  • the loading state of the rinsing device is detected according to a further feature of the invention by means of an optical detection device.
  • This detection device preferably has infrared LEDs and infrared sensors.
  • On the input side of the rinsing device a light grid having a plurality of parallel lines of light is formed.
  • the items to be washed are driven through the light grid, which then allows optical detection.
  • Such "learning” is as follows.
  • the flushing device is loaded with a possible constellation of items to be cleaned.
  • This loading condition is detected by the detection device.
  • the state thus detected is assigned on the user side to one of the cleaning programs available for selection.
  • the user can put together the cleaning program in question similar to a modular system of individual program blocks themselves and if necessary change individual program parameters. If, during normal operation, a loading state identical or at least similar to that of the purging device is learned, the loading state is detected and the program assigned to this loading state on the user side is started automatically.
  • the method implementation according to the invention is particularly suitable for a flushing device, which is used to clean bedpans, urine bottles and / or the like, d. H. for a bedpans cleaning machine.
  • a bedpans-cleaning machine is used in particular for the cleaning of bedpans, urine bottles and possibly chairs buckets.
  • a bedpan washer ware to be positioned at the appropriate places in the cleaning room of the bedpan automatic dishwasher.
  • a bedpan receptacle in the form of a wire frame is provided. This leaves with regard to the items to be cleaned, d. H. to be cleaned bedpans, urine bottles and / or buckets only predetermined positioning. Therefore, unique load conditions can be defined.
  • a possible loading condition is given, for example, by the fact that only urine bottles are available for cleaning.
  • a cleaning program for example, a short program is assigned to this loading state, which accordingly is cleaned exclusively with cold water and without the addition of chemical cleaners.
  • Another load condition results from the fact that at least one bedpan is to be cleaned, with or without a combination of urine bottles.
  • a loading condition can For example, be associated with a standard program that rinses, for example, according to at least one cleaning step with hot water.
  • An intensive program may be provided in case of special pollution.
  • an additional cleaning step using chemical cleaners may be provided.
  • a rinsing device for carrying out the method for automatic cleaning of items to be washed, in particular bedpans, urine bottles and / or the like, provided with a Spellerhunting Spülhunt having a closable by means of a door fluid-tight feed opening, and with an optical Detection device, which is formed as a plurality of parallel lines of light having light grid, which covers the feed opening at least partially.
  • the detection device is used in the previously described manner of detecting the loading state of the purging device. Depending on the detected load condition, a cleaning program is selected and started. There are several possible cleaning programs available, one of which is selected.
  • the "empty state of charge” is when there is no items to be washed within the rinsing chamber provided by the rinsing device. In this case, the at least automatic start of a cleaning program is excluded. Accidental cleaning can be prevented in this way.
