Definitions

  • the invention relates to a device for softening Fresh water in a cleaning device for dishes and / or tablet parts and a method for softening Fresh water during the continuous operation of one such cleaning device.
  • tap water To sustain damage to a cleaning device for crockery and / or tablet parts, hereinafter briefly as To avoid dishwasher, tap water must be avoided be softened with a regionally different hardness. For this, the tap water is passed through an ion exchanger conducted, which binds calcium and magnesium ions and through Sodium ions replaced. Depending on the volume of the Ion exchanger is exhausted relatively quickly and must be regenerated by reversing it Mass transfer step the bound magnesium and Calcium ions are replaced by sodium ions. This is carried out with the help of a saline solution, which during the regeneration of the ion exchanger through this becomes.
  • Another alternative is to put the ion exchanger in to control a two bed operation so that a continuous work is possible. During a Ion exchange bed is loaded, the other now regenerated. However, this operation is related on the control system complex and with high operating costs connected. In addition, one strives to internal softeners to be provided in the housing of a commercial Have the dishwasher integrated.
  • An internal softener has become known in the art a spring-loaded piston is controlled. Depending on the Positions of the piston are exposed or blocked a connection between the Ion exchanger tank and a soft water connection or but between the ion exchange container and the drain produce. During the passage of water to be softened it is softened in the exchanger tank and passes over the soft water connection to the subsequent stations of the Dishwasher while in one of those spring-loaded piston closed chamber a saturated Saline solution.
  • the exchange resin is in an ion exchange container fixed with the help of retention sieves. On this Retention screens can collect dirt particles and in the Block the sieve over the life of the device. It also depends on that predetermined spring pressure the same amount of saline solution in the device so that regardless of the locally present Water hardness of the ion exchanger with the maximum required amount of salt is regenerated. This is at this technical solution the salt consumption is very high.

  • a saturated saline solution generated that can penetrate the sieve and in the second, lower chamber of the salt container accumulates.
  • this chamber is the dosing device, so that the Dosing device integrated in the housing of the salt container can directly add a saturated salt solution to the water.
  • the sieve is preferably conical. This owns the advantage that dirt in the salt container not the sieve clogged, but on the sieve in the direction of gravity is discharged below. Therefore the service life of the sieve can be reduced increase significantly.
  • the device comprises still a valve that is only at a predetermined Fluid pressure opens automatically.
  • Providing one such valves allows the simplification of Control device of the entire softening device. By doing only in the step of producing softened water sufficient flow rate and thus a sufficient pressure is provided to do that All others will be able to open the valve automatically Operating stages of the softening device avoided that Salt in an undesirable manner to the soft water pipe can accumulate adjacent heater. A separate one Valve control is therefore not required.
  • the respective method steps are preferably carried out a control in the machine program of the cleaning device controlled.
  • the control of the Softening device completely in the overall control of the Dishwasher can be integrated and with this the Operation of the softening device analyzed and adjusted become.
  • the Control the frequency of regeneration to the specification of the Water hardness is therefore possible only after an optimally adapted predetermined number of operating cycles Regenerate ion exchanger tank. This measure too lowers the required salt consumption.
