Definitions

  • the present invention relates to a refrigerator and/or freezer with a pipeline and a cleaning chamber, wherein the pipeline is designed so that a fluid can flow in the pipeline.
  • Piping systems for transporting fluids such as water with municipal or large-scale technical or industrial applications are known from the prior art, which are designed in such a way that the introduction of a cleaning agent into a pipe of the system requires the pipe to be completely shut off and several units to be interposed is required.
  • Such an approach has disadvantages for introducing a cleaning agent into the pipeline of a household appliance, such as a refrigerator and/or freezer, particularly with regard to complexity and costs.
  • the present invention is based on the object of developing a refrigerator and/or freezer of the type described above in such a way that a cleaning substance can be easily introduced into a pipeline of a refrigerator and/or freezer.
  • the cleaning chamber is designed so that a fluid can flow in the cleaning chamber, the cleaning chamber also being designed to accommodate cleaning agents, the pipeline and the cleaning chamber being connected by connecting means in such a way that a fluid flowing in the pipeline Fluid can flow into the cleaning chamber and then from the cleaning chamber back into the pipeline.
  • the cleaning chamber is arranged in or on the pipeline.
  • screening means are arranged in the connecting means.
  • Sieving means can also only be arranged in one connecting means.
  • the connecting means are designed such that all of the fluid that can flow in the pipeline or only part of the fluid can flow into the cleaning chamber and then from the cleaning chamber back into the pipeline.
  • the cleaning chamber has a lid which is designed such that cleaning agents can be introduced into the cleaning chamber, wherein the lid can preferably be screwed to the cleaning chamber or is a hinged lid.
  • the lid is designed such that the lid can only be opened when no fluid is flowing in the cleaning chamber.
  • the lid and/or the cleaning chamber are designed such that no fluid can flow into and/or out of the cleaning chamber when the lid is opened.
  • the fluid has or is water.
  • the cleaning agent is or can be present in solid, liquid or gel-like form, the cleaning agent being surrounded, for example, with a water-soluble film.
  • the connecting means are designed such that the cleaning chamber can be arranged on or in the pipeline by plugging or screwing.
  • a cleaning chamber is preferably integrated, for example in the form of an adapter for introducing a cleaning agent into a pipeline in the form of solids in the form of, among other things, pressed powders or granules, as well as a cleaning agent in liquid and/or gel-like form, whereby these can be enclosed with a sheath by, for example, a (cold) water-soluble polyvinyl alcohol (PVOH) film.
  • a cleaning chamber is preferably integrated, for example in the form of an adapter for introducing a cleaning agent into a pipeline in the form of solids in the form of, among other things, pressed powders or granules, as well as a cleaning agent in liquid and/or gel-like form, whereby these can be enclosed with a sheath by, for example, a (cold) water-soluble polyvinyl alcohol (PVOH) film.
  • PVOH water-soluble polyvinyl alcohol
  • a pluggable and/or screwable and/or directly integrated pipe section is integrated into a water pipe, which is suitable for the direct insertion of cleaning substances in powder form, gel form and/or in liquid form, the cleaning substances having a PVOH Can be covered with foil.
  • FIG. 1 a pipeline 10 is shown with a cleaning chamber 20 arranged thereon.
  • a fluid such as water, can flow through the pipeline 10, which is shown by the thick arrows in the middle of the view of the pipeline 10.
  • the pipeline 10 has an internal junction which merges into a bypass line 11. Through the junction and the bypass line 11, a portion of the fluid from the pipeline 10 can be passed into the cleaning chamber 20 through an inlet.
  • the partial amount of cleaning agent present there can be dissolved.
  • the partial quantity then flows through an outlet again from the cleaning chamber 20 into the pipeline 10.
  • the flow direction of the subset is indicated by the less thick arrows in Fig. 1 indicated.
  • the attached cleaning chamber 20 has a lid 21, for example in the form of a screw cap, and can be opened by this, which makes it possible to introduce a cleaning agent into the cleaning chamber 20.
  • Sieving means 12 for example in the form of filters or sieves, are arranged in the inlet and/or the outlet. The undissolved or insoluble components of the cleaning agent are held in the cleaning chamber 20 by the sieve means 12.
  • the lid 21 of the cleaning chamber 20 is locked by internal pressure caused by the flowing fluid, so that the lid 21 is prevented from opening during operation.
  • the partial water inlet of the cleaning chamber 20 i.e. the inlet and/or the outlet, is closed, preferably in a fluid-tight manner. This prevents further fluid leakage.
  • FIG. 2 The left view shows a pipeline 10 with a cleaning chamber 20 arranged therein.
  • the cross section of the inlet and the outlet of the cleaning chamber 20 corresponds to the cross section of the pipeline 10.
  • the cleaning chamber 20 is thus integrated into the pipeline 10.
  • Sieving means 12 for example in the form of filters or sieves, are again arranged in the inlet and the outlet. The undissolved or insoluble components of the cleaning agent are held in the cleaning chamber 20 by the sieve means 12.
  • the cleaning chamber 20 is thus completely flowed through by the fluid flowing in the pipeline 10.
  • the cleaning chamber 20 has a lid 21.
  • the lid 21 is a hinged lid, as in the right view of Fig. 2 shown.
  • the cover 21 has the same curvature as the pipeline 10. When closed, the cover 21 thus forms a portion of the wall of the pipeline 10.
  • the cleaning agent can thus be supplied via the cover 21 or via a side opening of the pipeline 10.
  • the cover 21 can be opened, for example, by rotating it out and moving it translationally.
