Definitions

  • the present invention relates to a metering device for metering a two-component Geschirtherapiesmittels in a dishwasher, in particular transport machine or belt machine, wherein the Geschirtherapiesstoff has at least one alkaline component and at least one dispersant and optionally at least one complexing agent.
  • Generic metering devices are used in a wide variety of types of commercial dishwashers, in particular conveyor and belt machines.
  • the items to be washed are usually either transported in baskets or on a conveyor belt through different rinsing zones of the dishwasher and thereby cleaned.
  • dishwashing detergents are used, which are composed of different components, whereby these individual components or chemical substances have different tasks, such as e.g. on the one hand the dirt removal, on the other hand serve the protection of the machine and the dishes.
  • dishwashing detergents are used in which the individual components are mixed in a fixed ratio to one another.
  • the alkaline component usually present in the generic dishwashing detergents mainly serves to remove dirt, and may additionally contain corrosion inhibitors which serve to protect the machine and its parts against the aggressiveness of the alkali component.
  • a so-called dispersant is usually provided as a further component of the dishwashing detergent. This binds the calcium-magnesium ions in the water and thereby prevents their precipitation on the heating rods and the machine walls and thus the calcification of the dishwasher.
  • an additional disinfection or Bleaching component may be provided to chemically-thermally disinfect the dishes chemically or in conjunction with an elevated temperature.
  • the dishwashing detergent is always used as a ready-mixed product of the individual components necessary for the various tasks.
  • overdose of at least one component occurs, as the following examples show:
  • a dishwasher If a dishwasher is constantly operated with very hard or hard water, it must be dosed to prevent the formation of lime soap and to prevent the precipitation of lime (combined with defective heating rods, encrusted machines) as much dishwashing detergent as for the complexing (binding) of lime is necessary. This in turn automatically leads to overdosing of the other components present in the dishwashing detergent.
  • Another example of this overdosing is given when a dishwasher runs, for example, in continuous operation from 9 to 19 clock, without the rinsing liquor would be replaced during this time.
  • the dosage of the dishwashing detergent must be set so high that the cleaning success is satisfactory even at the end of the operating time.
  • an increased amount of dispersant is needed so that the other components of the Geschirthesesmittels are in turn overdosed.
  • the object of the present invention is therefore to provide a metering device with which the abovementioned disadvantages of the prior art are avoided.
  • the metering device (1) has at least two separate inlets for each at least one component of the Geschirtherapiesffens and a control or regulating device, wherein the control or regulating device, the individual components in one, preferably in advance and / or variable , adjustable amount ratio dosed each other in the dishwasher.
  • the metering device By means of the metering device according to the invention, it is possible to introduce the individual components of the dishwashing detergent via the separate inlets provided in the metering device, for example from separate storage containers, supply lines or the like, independently of one another and to dose them individually from there, whereby both economically and also From an ecological point of view, optimal adaptation of the dosage to the particular conditions in which a dishwasher is used becomes possible.
  • the composition of the dishwashing detergent can be adapted, inter alia, to the locally encountered degree of hardness of the water used, to the present degree of soiling of the dishes as well as to the total volume of the daily amount of dishes to be washed.
  • the quantitative ratio can be understood as meaning both a volume ratio and a mass ratio of the individual components to one another.
  • the metering device doses the components of the dishwashing detergent into the main wash zone, preferably into the main wash tank.
  • the components of the dishwashing detergent specifically added by the metering device are introduced directly into the area of the dishwasher in which they are essentially required.

  • a data input device preferably a keyboard
  • the quantity ratio (s) can be variably entered (depending on the time of day) into the rinse program (s) and can be stored in this rinse program (s).
  • the dosage of the individual components can be adapted to the daily schedule of the flushing requirement. This is for example cheap, if in the morning slightly soiled breakfast dishes, lunch heavily soiled lunch dishes, etc. is to rinse.
  • the wash program can be interrupted and at least one predefinable special wash program can be played during the interruption of the wash program.
  • the metering device is used as a control device by having at least one measuring device for determining at least one controlled variable.
  • the controlled variable provides information about the instantaneous state of the rinsing liquor present in the dishwasher and can be used, for example. be used by the control or regulating device, if necessary, continuously adjusts the measured controlled variable by dosing at least one component of the Geschirtherapiesstoffs to a predetermined, preferably time-variable setpoint.
