Definitions

  • the invention relates to a device for water softening according to the preamble of claim 1.
  • Water softener especially for household machines like Dishwashers, washing machines or the like exist in usually from a container, for example in the An inlet in the bottom area and an outlet in the lid area having. Usually is located above the inlet a sieve on which a filling of softening material, for example resin is filled up. So that Softening material is not washed out, it is sent to him A sieve is also attached to the top.
  • the container that Usually consists of plastic, is using a welded lid closed, which, if necessary, the Can include runoff.
  • the current water softeners have the disadvantage that there are so-called breakthroughs in the flow of water during the Softening can come. That means channels form within the softening process, in the raw water can flow through almost without contact with the softener mass. As a result, this is the case after softening Water does not have the desired degree of hardness.
  • the invention has the task of a device to propose water softening at which one reliable softening takes place.
  • the Limitation of the filling volume at least partially against one Resilient force trained This will avoided that with an increase in volume of the Softening material after filling and sealing the Container by increasing the volume of the softening material for example due to increasing exposure to appropriate softening processes, too much pressure in the Inside the filling volume is built up, the Retaining elements for the softening material or would burden the container wall. So the mechanical Resilience, for example of the softening container or No retention elements compared to previous versions be changed. It is also guaranteed that the Flow resistance inside the softening material is not is subject to fluctuations due to different densities.
  • the container wall at least partially be elastic.
  • Another way to Realization of the invention would consist of one or more to form the retaining elements elastically.
  • a Retaining elements such as a sieve or the like can be used for Realization of the invention by means of spring force on the Softening material to be pressed.
  • too one or more expansion elements for volume compensation in the Be provided inside the filling with softening material For example, gas-filled balloons come into question Made of elastic material, the pressure of the Softening material can give way when volume increases and with a corresponding decrease in volume of the softening material expand again. Others would also be conceivable Expansion elements, for example cylinder systems or the like.
  • the Retaining elements for the softening material elastic or not elastic, for example in the conventional way be formed as a sieve.
  • the container lid and / or base is preferably used here at the end under spring pressure on the softener tank attached.
  • the filling volume is arranged so that the corresponding component, i.e. the container lid and / or - Bottom also the filling volume of the softening material immediately limited without a retaining element arranged in between is.
  • the drain and / or Inflow over several wall openings distributed on the circumference manufactured, with corresponding, arranged outside at least partially annular drain or inflow lines are also provided on the circumference.
  • a particularly advantageous embodiment for production a softener according to the invention is in use a lid with a rigid or elastic central area, the by means of a resiliently curved Edge area pressed onto the softening material and on the Wall of the softener tank is attached.
  • the single figure shows a schematic cross section through an inventive device for water softening.
  • the figure shows a softening container (1) the underside of which is arranged an inlet (2). in the There is a sieve (3) at the bottom. Above the sieve (3) there is the filling volume (4) in which hatched shown softening material is filled.
  • a cover (5) is above the softening material Limitation of the filling volume (4) of the softening material arranged, which has a central region (6), the for example membrane-like from a flexible, possibly resilient material.
  • the middle part (6) merges into an annular bead (8), which is S-shaped is and preferably also made of resilient, elastic Material exists.
  • the ring bead (8) ends in a ring collar (7), which at weld points (9) with the container wall (19) to connect, for example to weld.
  • intermediate slots (13) are partly in the cover (5), partly in the container wall (10), between which correspond to each other by dashed lines indicated intermediate slots (13) are.
  • the Intermediate slots (13) can be made narrow that the grains of the softening material have a larger one Have diameter and thus the softening material (4) cannot escape. There are none in this training additional retaining elements required.
  • the slots (13) are distributed around the circumference and are sealed on the outside by a hollow sleeve (11). Each the more slots (13) are installed, the larger the Flow cross section for the drainage through these slots (13) in the hollow sleeve (11) takes place as by the Arrow (P) indicated.
  • the hollow sleeve (11) opens into a drain line (12) with the wash cabinet or with the Swamp of a household machine no longer shown connected is.
  • Raw water flows in the direction of the arrow (Z) for softening via the inlet (2) inside the softener tank (1).
  • the sieve (3) acts as Retention element for the softening material in the filling volume (4) and is permeable to the raw water that consequently in The softening material flows upwards.
  • the raw water is in contact with the softening material a corresponding ion exchange softens.
  • the filling volume (4) completely be filled with softening material. Then the Cover (5) pressed on until the collar (7) on the Container wall (10) bumps. As soon as the lid (5) with the Middle area (6) abuts the softening material, the Cover (5) through its at least partially elastic Training after, while the collar (7) continues down can be pressed in the direction of the container wall (10). To the welding at the welding points (9) is thus so to speak, the lid (5) in its springback Prestressed components. It is therefore in the Filling volume (4) of the softening material no free Compensation volume for the compensation of a change in volume of the Softening material.
  • the at least partially resilient design of the lid (5) differences in Degree of filling of the filling volume (4) can be compensated without that a free volume arises.
  • the requirements for Filling tolerances can accordingly be set low become.
