  • the invention relates to an exchange and / or refill housing for a water filter according to the preamble of claim 1.
  • Such replacement and / or refill housings are used in private and commercial kitchens or sanitary facilities.
  • Exchange and / or refill housings in the interior of which there is a filter substrate, are known.
  • the filter is designed, for example, as a powder filling, as a granulate filling or by means of a cartridge, in the interior of which the filter substrate is located.
  • Exchange and / or how the filling housing are usually enclosed by an outer housing and form an assembly.
  • the outer housing is used to hold the replacement and / or refill housing also for connection to the water pipe. Since the cleaning function of the filter substrate decreases with increasing amount of water flowing through, it is important that the filter substrate can be cleaned and / or replaced after a certain amount of water flowing through.
  • the object of the invention is to provide a water filter in which the exchange and / or refill housing can be replaced and / or cleaned and / or refilled easily, hygienically and inexpensively.
  • the exchange and / or refill housing is encapsulated within the outer housing and the water inlet and water outlet covers.
  • the sealing concept can be carried out using O-rings.
  • the 0-rings are placed on the water inlet cover and on the water outlet cover and the exchange and / or refill housing and prevent the water from coming into direct contact with the outer housing and at the same time enable simple and quick replacement of the exchange and / or refill housing ,
  • this can be produced as a two-part plastic housing in an injection molding process.
  • the Filter substrate can be installed before or after the two

  • the connection of the two plastic parts can advantageously be realized by means of ultrasonic welding processes.
  • the exchange and / or refill housing and the outer housing can have a cylindrical shape.
  • the water filter assembly consisting of outer housing, water inlet cover and water outlet cover and the replacement and / or refill housing according to the invention and its filling with a filter substrate is primarily for use in households for cleaning the water made available from the water line for the purpose of consumption suitable.
  • the exchange and / or refill housing ensures the filter function by simple and inexpensive exchange and / or refill and / or cleaning.
  • the water filter consists essentially of a three-part outer housing, in which the exchange and / or the refill housing is located, e.g. is filled with a filter substrate made of activated carbon.
  • the water filter is installed in the installation in such a way that the water flows into the lid water inlet, is cleaned within the exchange and / or refill housing, and through the lid water outlet re-enters the water pipe and then e.g. flows out at the tap.
  • the sealing by means of O-rings prevents the water from coming into contact with the metal of the outer housing.
  • the outer housing can be made of metal.
  • the exchange and / or refill housing can consist of a renewable, biodegradable raw material, for example of wood.
  • the water filter has a stable outer housing made of metal, but this does not come into contact with the medium to be cleaned and thus does not cause any unsanitary and / or unhealthy impurities by dissolving

Abstract

L'invention concerne un logement d'échange et/ou de recharge conçu pour un filtre à eau qui est agencé dans un logement externe d'un ensemble et qui est rempli d'un substrat de filtration conçu pour la purification d'eau. Le matériau du logement externe de l'ensemble n'entre pas en contact avec le milieu à nettoyer, ce qui n'entraîne aucunes impuretés non hygiéniques et/ou nocives pour la santé. En outre, le remplacement, la recharge et le nettoyage du logement d'échange et/ou de recharge sont simples et peu onéreux.
