Definitions

  • the following invention relates to an ice maker for the production of transparent pieces of ice and a refrigeration device, which is equipped with such an icemaker.
  • Ice makers for home refrigerators are known in a variety of designs.
  • a simple form of ice maker has a water tank, which is divided into several each of the shape of a piece of ice predetermining chambers.
  • the ice is produced by the temperature of a cooling compartment in which the water tank is located below 0 0 C is lowered.
  • the resulting ice cream is not crystal clear, but interspersed with a variety of welts or bubbles, which make the piece of ice appear dull as a whole.
  • an ice maker has been proposed for automatic ice making, in which a plurality of cold fingers in a contiguous chamber of a
  • Ice layer whose thickness increases over time.
  • Ice pieces can be easily and reliably released from the fingers. Again, the resulting ice cream is generally not transparent.
  • a clear ice maker with a water tank and a supply line for filling the water tank with fresh water, in which an osmosis filter is connected in series in the supply line.
  • Such a filter proves to be surprisingly effective in preventing turbidity in the ice, and it is believed that the reason is that nuclei contained naturally in the tap water are kept away from the water tank by the osmosis filter. Since these crystallization nuclei are not incorporated into the crystal structure of the forming ice, there are no starting points from which vesicle or striation forms.
  • This basic principle of the invention is applicable to all known types of ice makers, in particular those with water tanks subdivided into a plurality of chambers or also those with a cooling body immersed in the water tank.
  • the water tank should have a drain for residual water.
  • Such residual water drainage can be expediently connected to a concentrate outflow of the osmosis filter.
  • a check valve is preferably located in the supply line upstream of the osmosis filter. Thus, while no fresh water is poured into the water tank, the filter can be kept without pressure.
  • a restrictor element is preferably inserted in a concentrate discharge line of the osmosis filter.
  • the invention also provides a refrigeration device with a clear ice maker as defined above.
  • FIG. 1 shows a schematic section through a refrigerator with a Klareisper according to the present invention.
  • a water tank 3 In the interior 1 of a refrigerator 2, a water tank 3 is arranged.
  • a cooling unit 4 is shown in a position in which its cooling fingers 5 engage from above into the water tank 3 and immerse it in water therein.
  • the cooling unit 4 may, as indicated in the figure, be formed by a Peltier element which is acted upon by direct current so that the cooling fingers 5 form a cold side and opposite to the cooling fingers protruding ribs 6 a warm side of the Peltier element. By cooling the cooling fingers 5, a piece of ice is formed in each of these in a conventional manner.
  • An electronic control circuit not shown controls the power supply of the Peltier element and, after a predetermined period of time in which the pieces of ice have reached a desired dimension, but not yet merged, a movement of the cooling unit 4 away from the water tank 3 and through a collecting 7. In In this position, the control circuit reverses the current direction of the Peltier element, so that the cooling fingers 5 heat up and the pieces of ice dissolve and fall into the collecting container 7.
  • an osmosis filter 8 is arranged outside the heat-insulating housing of the refrigerator 2.
  • filters used in particular in the aquarium for water treatment contain in a housing a large-area semipermeable membrane which is permeable to water, but not for dissolved ions and suspended particles therein. If there is hydrostatic overpressure on one side of the membrane, water can pass through the membrane increasing the ion concentration on the overpressure side until the difference between the osmotic pressures on both sides of the membrane compensates for the hydrostatic pressure differential.
  • the filter process does not stop when this pressure difference is reached, such a filter is operated in the flow; that is, it has an inlet port 9 for fresh water and an outlet 10 for ion-enriched water, so-called concentrate, on one side of the membrane and a filtrate outlet 11 on the other side of the membrane.
  • the fresh water inlet 9 is connected via a check valve 12 to the drinking water network, while the Konzentratauslass 10 is connected via a provided with a throttle 13 line 16 to a sewer and the filtrate 1 1 opens into the water tank 3.
  • the throttling point 13 limits the flow of water through the check valve 12 and causes the build-up of an overpressure on the concentrate side of the osmosis filter 8. This overpressure drives the passage of purified water to the filtrate side.
  • the filtered water passes through the filtrate 1 1 in the water tank 3.
  • the control circuit closes the check valve 12 again, and the pressure in the filter 8 is equalized , Now, as described above, the cooling fingers 5 are cooled until ice pieces of a desired size are formed thereon. After the formation of ice in the tank 3 remaining water is removed by the control circuit opens the check valve 15 temporarily. Then a new ice-making cycle can begin.
