Definitions

  • the present invention relates to a refrigerator and/or freezer with a filter unit for filtering water, the filter unit having an inlet for water to be filtered, an outlet for filtered water and a filter material located between the inlet and outlet, the filter material being in one Filter room is arranged.
  • the filter unit is used to clean or filter water that is supplied, for example, to an ice maker in the device or a water dispenser in the device.
  • filter units which contain, for example, weakly acidic cation exchangers as filter material, are necessarily flowed through in a vertical flow direction, so that the force of gravity ensures that the filter medium is in the best case as a fixed bed variant. Due to the existence of a fixed or floating bed, pressing is not necessary for functionality.
  • the present invention is based on the object of developing a refrigerator and/or freezer of the type mentioned in such a way that the filter unit allows great flexibility with regard to the installation position and ensures a good flow through the filter material regardless of the installation position and the condition of the filter material is.
  • the invention provides that the filter space is designed in such a way that the filter space can adapt to a change in volume of the filter material.
  • expansion of the filter material can preferably be compensated for, so that no critical condition can be achieved within the filter housing due to the expansion.
  • the filter unit is installed in a horizontal position, water flowing past in the media-free area can be avoided.
  • the filter unit is flowed through in a horizontal direction.
  • the filter space is delimited on the inlet and/or outlet side by filter disks, with the inlet-side filter disk preferably being arranged firmly and the outlet-side filter disk being arranged loosely.
  • the filter disk on the drain side or the membrane through which the already reacted drinking water flows is mounted flexibly in the translational direction.
  • the filter space in the area of the inlet and/or outlet is at least partially delimited by a material which has such material properties that the filter space can expand with the filter material.
  • the inlet or outlet consists entirely or partially of a material which has a high coefficient of elasticity, so that the separating membrane is displaced when the filter material expands in the course of the filter process and the inlet and/or outlet line is extended.
  • the inlet comprises an inlet pipe which is partially or completely surrounded by the filter material.
  • the inlet has an outlet and that deflection means are provided which are designed to divert the water from the outlet to the filter material, preferably by 180°.
  • inlet and the outlet are arranged relative to one another in such a way that the water can flow in opposite directions in the inlet and outlet.
  • outlet of the filter unit is in fluid communication with an ice maker or water dispenser of the device.
  • the inlet of the filter unit is in fluid connection with a fixed water connection of the device.
  • the filter material has or consists of a resin for ion exchange.
  • a filter unit is identified by reference number 10.
  • This has a housing 100 and a filter material 1 located therein.
  • the housing is preferably circular in cross section, i.e. the housing has a cylindrical lateral surface overall.
  • Filter disks are identified by reference numbers 3 and 4, which extend at a distance from one another over the entire cross-sectional area of the housing and accommodate the filter material 1 between them in the axial direction, that is to say the disks 3, 4, together with the housing 100, delimit the filter space in which the filter material 1 is located.
  • the filter material 1 may be porous and may include or consist of a resin.
  • inlet pipe which has an inlet 101 and an outlet 102.
  • the thick arrows mark the direction of water flow.
  • the water initially flows, for example, from a fixed water connection of the device into the inlet 101 of the inlet pipe, which extends in the axial direction of the filter unit 10.
  • the water emerges from the outlet 102 and hits the inside of the internally rounded, partially spherical end cap of the housing 100. It is deflected by 180 ° by means of the end cap and then passes through the first filter disk 4, which can be designed as a sieve and occurs after flowing through the filter material 1 from the second filter disk 3.
  • the first filter disk 4 is preferably fixed and the second filter disk 3 is preferably arranged loosely.
  • the housing 100 which serves as a boundary for the filter material, has a material 2 which is stretchable in such a way that the filter space can expand with the filter material 1.
  • the housing and/or the inlet pipe can preferably lengthen by an amount D. It is also conceivable that the filter disk 3 on the drain side can shift, preferably by an amount D, when the filter material expands. It is also conceivable that the filter space increases when the filter material expands due to an expansion of the housing 100 and/or the inlet pipe and/or a displacement of the filter disk 3 on the outlet side, preferably by an amount D.
  • the housing 100 can be made of this material, or only a portion of the housing 100 can have this material.
  • the inlet pipe can also be removed this material, or only a section of the inlet pipe can have this material.
