Definitions

  • the present invention relates to a refrigeration device having an interior for storing refrigerated goods, in particular a domestic refrigerating or freezing device, which has a water inlet connection, a tapping point for cooled water and a water cooler arranged on a water line between water inlet connection and tapping point.
  • a refrigeration device having an interior for storing refrigerated goods, in particular a domestic refrigerating or freezing device, which has a water inlet connection, a tapping point for cooled water and a water cooler arranged on a water line between water inlet connection and tapping point.
  • Devices of this type which can be connected to a drinking water network to supply a user with chilled water at any time and without the need to refill containers, are becoming increasingly popular.
  • the water cooler is realized as a tank which can be filled with water from the water inlet connection and which is in thermal contact with the interior space in order to cool the water contained therein.
  • a disadvantage of such a water cooler is that, when water flows out of the tapping point, uncooled fresh water immediately flows into the tank, and when it mixes with the cold water already in the tank, it causes the temperature of the tapped water to fall begins to rise after tapping a small amount. If the inflowing water does not mix with the chilled water in the tank, the temperature of the tapped water rises abruptly as soon as the tank contents are completely replaced.
  • the cooling of the tank contents takes place by the air of the interior heated to the tank contents and the absorbed heat gives off to an evaporator.
  • the heat exchange through the air of the interior is slow, especially when between the tank and the interior still an insulating layer is provided, so that in the tank nachgeströmtes fresh water takes a long time to cool.
  • Object of the present invention is to provide a refrigeration device that allows the tapping of larger amounts of cooled water or rapid cooling of nachströmendem fresh water.
  • a refrigeration device with an interior for storage of refrigerated goods and with a water inlet port, a Refrigerated water tap and a arranged on a water line between the water inlet port and tap water cooler of the water cooler comprises a container for a liquid or solid heat storage medium and a guided in thermal contact with the heat storage medium water pipe section.
  • the liquid or solid heat storage medium allows a much faster heat exchange than the air of the interior, so that water can be cooled in the flow through the water cooler to a desired drinking temperature.
  • a tank for the water is not required.
  • the heat storage medium having a melting point above 0 0 C and a refrigerator of the household refrigerator is designed to freeze the heat storage medium, a small amount of the heat storage medium is sufficient to cool a large amount of water by receiving heat of fusion.
  • the water cooler can therefore be constructed compact.
  • the water line section is preferably passed through the heat storage medium.
  • the latter is preferably helical.
  • the water pipe is preferably sloping between the water cooler and the tapping point, so that at the end of a tapping process water from the water pipe section of the water cooler or the adjoining water pipe can flow completely out of the refrigerator. Such a drain is further facilitated by the fact that the water pipe is kept free from the water cooler of shut-off elements.
  • a ventilation opening is preferably formed on the water line between the water inlet connection and the water cooler.
  • a valve suitably arranged on the ventilation opening prevents the escape of water through the ventilation opening.
  • FIG. 1 shows a schematic section through an inventive refrigeration device.
  • FIG. 2 shows an enlarged detail of the refrigeration device in section according to a first embodiment
  • Fig. 4 shows the same detail as Fig. 2 according to a second embodiment.
  • Fig. 1 shows a section through an inventive refrigerator with a body 1 and a door 2, which enclose an interior space 3 for storage of refrigerated goods.
  • a per se known, not shown in the figure chiller comprises an evaporator for cooling the interior 3, which is arranged communicating, for example, on a rear wall of the interior 3 or in a separated chamber from the interior 3 and the interior 3 via a forced ventilation.
  • the refrigerator may be a refrigerator or freezer.
  • a water pipe 4 extends from a drinking water mains connection, not shown, through the walls of the body 1, a hinge connecting the door 2 to the body 1, and the door 2 itself to a tapping point 5 which is located in a door 2 formed, outwardly open niche 6 is arranged.
  • a check valve 8 disposed on the water pipe 4 is operable by a switch 8 disposed in the niche 6 to detect the presence of a container to be filled in the niche 6 and to release the flow of water through the check valve 7 only when a container is in the niche 6 is detected.
  • the switch 8 has an arm 9 which is displaced by a placed in the niche 6 container against the rear wall of the niche 6 and thereby actuates the switch 8 and the check valve 7 opens.
  • a control button 10 may be provided for opening and closing the check valve 7 on the outside of the door.
  • the water cooler 9 is a container embedded in an insulating material filling the door 2, which is filled with a solution whose freezing point is just above 0 0 C.
  • the thicknesses of insulating layers 12, 13, which separate the water cooler 9 on the one hand from the interior 3 and on the other hand from the environment, are so dimensioned when the device is placed in a normal temperature room and the interior 3 is kept at a normal operating temperature, the solution freezes, but their temperature remains above 0 0 C.
  • a portion 14 of the water pipe 4 extends within the water cooler 9 helically down to the arranged on the ceiling of the niche 6 tapping point 5.
  • the running through the radiator 9 section 14 is integral with a downhill through the insulating layer of the door 2 to the tapping point 5 extending line section
  • the cross-section of the line sections 14, 15 can be chosen so large that when the check valve 7 closes, air at the tap 5 penetrates into the line and the water contained in the sections 14, 15 gradually drains.
  • Fig. 2 shows a section through a portion of the water pipe 4 between the check valve 7 and the water cooler 9 according to a first preferred embodiment of the invention.
  • a nozzle 16 is formed, which directs a water jet through a chamber 17 to a leading to the water cooler 9 drain opening 18 in a nozzle 16 opposite wall of the chamber 17.
  • the check valve 7 is embedded in the immediate vicinity of the water cooler 9 in the door 2, connects a passage 19, the chamber 17 with the interior 3.
  • the passage 19 could also lead to the outside.
  • the chamber 17 behaves similar to a water jet pump; Although air can be sucked through the passage 19 into the chamber 17, but there is no water from the passage 19 from. By air 7 flows after the blocking of the valve 7 through the passage 19 into the chamber 17, the water from the cooler 9 can flow quickly into a placed in the niche 6 container.
  • the conduit portion 15 connecting the radiator 9 to the tapping point 5 slopes down and, like the conduit portion 14, is free of flow obstructions such as bottlenecks or valves that might retain water in the conduit portion 14 or 15.
  • the line sections 14, 15 empty quickly and completely after each dispensing operation. In the embodiment of FIG. 2, it may possibly come to a backwater of water, if the flow resistance of the line sections 14, 15 is not small enough.
  • Fig. 4 A further developed embodiment, which prevents the escape of water in such a case, is shown in Fig. 4 in a similar to Fig. 2 section.
  • the chamber 17 is omitted here; Instead, the passage 19 branches off from the line 4 extending directly from the check valve 7 into the water cooler 9.
  • a valve seat 22 On protruding into the passage 19 projections 20 rests a spherical float 21, and above the float 21, a valve seat 22 is formed. As water accumulates in the conduit 4 downstream from the check valve 7, it enters the passage 19, lifts the float 21 from the projections 20 and pushes it against the valve seat 22. This obstructs the passage 19 and forces the water to flow. to flow through the radiator 9. If, after closing the check valve 7, the pressure on the line 4 decreases, the float 21 moves away from the valve seat 22, and the air flowing past the float 21 through the passage 19 facilitates complete emptying of the line sections 14, 15.
