Definitions

  • the invention relates to a household refrigerating appliance, comprising a thermally insulated inner container which is designed to form a closable by a door leaf cold room for storing refrigerated goods and having a container wall with a drain which is designed to run in the inner container settled condensation from the inner container ,
  • the DE 10 2004 045 477 A1 describes a household refrigeration appliance whose body provided with a door opening comprises an inner container, an outer wall and a space filled with insulating material between outer wall and inner container, and in which a drain line for water from a lowest point of the bottom of the inner container through the gap to the outside extends and a pull-out of the body conduit portion which is guided in an embedded in the insulating material and sealed against it pipe.
  • the inner container is formed on the side of the door opening with a circumferential ridge.
  • the tube is connected to an outlet formed in the web.
  • the tube has sealing means which seal the tube against the outlet.
  • the DE 10 2006 018 423 A1 describes a refrigeration device with a condensate drainage system, with which the condensate is passed through a condensate drain hose and a siphon from the inside of the refrigerator to the outside.
  • the siphon material may be coated with silver or copper based additives.
  • the DE 103 23 851 A1 discloses a refrigerator with a collecting and evaporation tank with a thermally coupled to the receptacle heat exchanger, the heat exchanger comprising a built-in a wall of the collecting container pipe, which thereby assumes a supporting function for the collecting container.
  • the pipeline may be a copper tube to release antibacterial copper ions.
  • the object of the invention is to provide a household refrigerator with a hygienic condensation water outlet, which has a simple structural design.
  • a domestic refrigerator comprising a thermally insulated inner container, which is designed to form a closable by a door leaf cold room for storing refrigerated goods and having a container wall with a drain, which is formed in the inner container settled condensate drain from the inner container by leaving an insert with a microorganism-effective material disposed on the drain.
  • microorganisms are in particular fungi, algae or bacteria.
  • Germs may be, for example, bacteria or other germs, such as molds. Germs can multiply in household refrigerators on food, especially spoiled food. Particularly at risk in the domestic refrigeration appliance, all components of a condensation water outlet, since there can accumulate condensate but also spilled liquid food fractions. Despite low temperatures in the household refrigerator certain germs can multiply well, especially if a regular cleaning of the household refrigerator is omitted. In particular, drain lines of a condensate drain and evaporation trays can not be cleaned by a user of the household refrigerator or only with great effort.
  • an insert with a material effective against microorganisms such as fungi, algae or bacteria is arranged on the outlet.
  • the present invention is based on the finding that an effective reduction of the spread of microorganisms can already be ensured by the provision of a separate with respect to the operation insert with a corresponding material.
  • the sequence ie all components required for draining the dew water deposited in the inner container, such as, for example, the drain opening, the drainage channel and the evaporation tray, remains unchanged.
  • the known from the prior art modification of the process is such that an integral part of the process is to be made of a propagation of microorganisms reducing material, thus not necessary. This results in a very simple and inexpensive construction. It is also possible to have conventional refrigerators that do not have special provisions for reducing the spread of microorganisms with a corresponding insert remove or retrofit without having to make design changes to the process.
  • the material effective against microorganisms secrete metal ions, in particular copper ions and / or silver ions. It is also conceivable, of course, that the material active against microorganisms alternatively or additionally comprises further chemical compounds which kill microorganisms or reduce their spread.
  • the insert is made entirely of copper.
  • the insert may for example be a cast part of copper or be, for example, a disc or a ring, which may be made of a copper plate or a copper sheet, in particular punched out.
  • Such insert is relatively easy and inexpensive to use even in small quantities; Also, the insert can be used by a fundamentally intended for a different purpose purpose machine part misuse, such. a washer made of copper as an insert.
  • the insert part has a copper-containing coating.
  • the insert may in this case have a carrier body made of a different material.
  • the coating may be formed entirely of copper.
  • copper and copper alloys such as bronze or brass can be used or materials that have only copper and / or silver additives.
  • the insert can be attached to a location that is particularly at risk to set up microorganisms. In particular, these can be places where condensation can accumulate without completely draining immediately.
  • a drain opening in particular a drain opening provided with a drain or an evaporation tray, may be particularly endangered to apply microorganisms.
  • the drain may comprise as components, for example, a drain opening, a drainage channel and / or an evaporation tray.
  • the insert may be disposed on one or more of these components. In the context of the invention, the use of a plurality of physically separate insert parts in a single flow of a household refrigerator.
  • the inner container may for example be an inner container of a freezer compartment.
  • the inner container may be an inner container of a freezer compartment, which is part of a combined refrigerator / freezer.
  • a bottom wall which has a drain opening for draining condensation, can be designed in particular trough-shaped.
  • the bottom wall may have a peripheral raised edge portion.
  • the bottom wall may in particular be a partial section of the inner container.
  • the drain can also have a condensation drainage channel which is arranged, for example, on a back wall of the inner container facing the refrigerated goods storage space.
  • the condensation drainage channel can be arranged, for example, below a vaporizer or an evaporator plate fastened to the rear wall of the inner container in the refrigerated goods storage space.
  • the condensation drainage channel can have an inclined channel along which condensation water can flow off due to gravity, in which the condensation water is fed to a discharge opening in the condensation drainage channel.
  • the condensation drainage channel may have an insert in the form of an inserted channel made of copper. Alternatively or additionally, an insert part made of copper can be arranged at the drain opening in the condensation drainage channel.
  • the drain may comprise as components a drain port, a drain channel, and / or an evaporation cup, and the bit may be disposed on one or more of these components.
  • a drain so not only a drain opening is understood, but an entire system of components that are set up or designed to lead out in thedegutlagerraum resulting condensation from the household refrigerator, in particular from the interior or introduce it to a specific point of the household refrigerator, for example an evaporation tray, which can be arranged in particular above a compressor of a refrigerant circuit of the household refrigerator.
  • the drain can have a drain opening and an annular insert part concentrically surrounding the drain opening, attached to the drain opening and / or inserted.
  • the annular insert made of copper can be formed, for example, by a circular copper body having a hole in the middle.
  • the annular insert made of copper may be formed, for example, in the manner of a washer.
  • the drain may have a drain opening with a recess into which a particular annular insert made of copper is inserted.
  • the drain opening may, for example, have a funnel-shaped depression.
  • the drain opening may also have a circular bottom with a drain hole, which may be followed by a circular cylindrical jacket wall at the circular edge of the bottom, the upper shell wall edge may end at a bottom wall of the inner container of the household refrigerator.
  • the circular cylindrical jacket wall may have a jacket wall height that is greater than the thickness of the annular insert made of copper.
  • the annular insert part may have a thickness or a height which is smaller than the jacket wall height of the circular cylindrical jacket wall of the drain opening.
