Definitions

  • the present invention relates to a refrigerator with a water tank, in particular with a water tank, which is provided to be connected via an inlet port to the drinking water network, and which feeds a drinking water dispenser or the like via an outlet port.
  • an inner structure of the tank is expedient in which it is divided by sections arranged in its interior into sections which are successively flowed through by the water on the way from the inlet connection to the outlet connection. Chilled water is thus displaced by inflowing fresh water substantially without mixing, so that the temperature of the tapped water begins to increase only when the tank contents is completely replaced.
  • the inlet port is located at a lowest point and the outlet port is located at a highest point of the tank. So is air originally contained in the tank by the inflowing
  • the object of the invention is therefore to provide a refrigeration device with a water tank, on the one hand prevents uncontrolled mixing of cooled water and fresh incoming water, but can be fully vented without difficulty or emptied.
  • a refrigeration device with a water tank having an inlet port and an outlet connected to a water dispenser and arranged by at least a first arranged inside its lamella in the tank contents on the way from the inlet port to the outlet port successively traversed sections is, wherein the sections merge at a free edge of the slat into each other, the slat is provided with a spaced from the free edge, the sections connecting passage opening whose free cross section is smaller than the free cross section of the respective sections. Depending on the location, these passages allow the passage of water or air that would otherwise be trapped in the tank.
  • the cross section should expediently be at most some percent of the cross section of the sections.
  • the passage opening is expediently formed at a lowest point of the lamella, or vice versa.
  • the through opening is preferably arranged adjacent to this opposite edge.
  • a plurality of first slats are rectilinear and parallel to each other.
  • the lamellae may be formed alone on the shell.
  • columns are preferably distributed over the bottom of the shell, which are firmly connected to the lid.
  • the tank is divided into a mixing area and a laminar flow area, with mixing in the mixing area of its contents is possible with fresh incoming water, while it is substantially suppressed in the laminar flow area.
  • the laminar flow area is divided into sections by the above-mentioned first fins
  • the mixing area is substantially free of first fins.
  • the mixing area is adjacent to the inlet port and the laminar flow area is adjacent to the outlet port, so that when tapped in the mixing area, mixed water whose temperature gradually rises in the course of a bleed operation, moves into the laminar flow area.
  • the outlet port is conveniently placed at a highest point of the water tank.
  • a ventilation opening expediently connects the highest point of the mixing area with the outlet connection.
  • the water dispenser is expediently provided with a lip valve.
  • FIG. 1 shows a schematic section through an inventive refrigeration device.
  • Fig. 2 is a schematic section through a water tank illustrating the basic principle of the invention
  • FIG. 3 is a perspective exploded view of a water tank according to a further developed embodiment
  • Fig. 5 is a perspective view of the shell of a water tank according to a modified embodiment.
  • the refrigeration device shown in a schematic section in FIG. 1 has a heat-insulating body 1 and a door 2 which delimit a cooled interior 3.
  • a central region of the door 2 an outwardly open niche 4 is formed, on the ceiling of which an outlet 5 for tapping cooled drinking water into a container 6 placed in the niche 4 is arranged.
  • the outlet 5 is connected via a supply line 7 with a placed in a rear wall of the niche 4 water tank 8.
  • the water tank 8 is surrounded on all sides by an insulating material layer of the door 2.
  • the water tank 8 is connected to the drinking water network via a line 9 which extends from the water tank 8, first through the door 2 via a hinge into the body 1 and along the rear wall thereof.
  • the conduit 9 crosses a base portion 10 of the body, in which a (not shown) compressor is housed.
  • a local heating of the line 9 by waste heat of the compressor or a (also not shown) generally outside mounted on the rear wall of the body 1 condenser can therefore not be excluded.
  • a check valve 33 is arranged at any suitable location, which shields the water tank 8 in the closed state before the pressure of the drinking water network.
  • the supply line 7 leading from the water tank to the outlet 5 can therefore be open in the simplest case; Preferably, however, a per se known lip valve is arranged at the outlet 5 in order to prevent a spontaneous outflow from the water to the outlet 5 down sloping part of the supply line 7.
  • a key 34, via which the blocking valve 33 can be opened and closed for the purpose of tapping off water, is arranged on the door adjacent to the niche 4.
  • Fig. 2 shows a section in a plane parallel to the door 2 through the water tank 8 according to a first embodiment of the invention.
  • the tank 8 has a substantially trapezoidal outline with an upper wall portion 19, a lower one
  • Outlet port 17 are formed at the lower and upper wall portions 20 and 19, respectively.
  • the connections 16, 17 also form the lowest or highest point of the tank 8, if, due to tolerances in its installation, its side walls 35, 36 are not oriented exactly vertically.
  • each fins 24 extend at right angles into the interior of the tank 8 inside.
  • the slats 24 each have a free edge 37, whose distance from the respective opposite side wall is approximately as large as the distance between the parallel slats 24 with each other.
  • the fins 24 divide the interior of the tank into a plurality of elongated sections 38, which merge into each other at the level of a free edge 37.
  • Each lamella 24 has at its connected to the side wall 35 or 36 edge a through hole 39, the free cross section is substantially smaller than that of the sections 38. If these through holes 39 were not present, would remain when filling the tank under each with the side wall 36 associated fins 24 caught above a dashed line 40 air. This would, if it expands upon heating of the tank 8, bring the outlet 5 to drip. Further, if, during a bleed operation, the check valve 33 is open and the pressure in the tank is correspondingly higher than the atmospheric pressure, it would be compressed and would expand again after closing the check valve 33 and so to run after Outlet 5 lead. The passage openings 39, however, allow this air to rise in the tank and finally reach the outlet port 17 along the top wall 19. Thus, under normal operating conditions, the tank 8 is free of air and dripping or hunting is avoided.
  • Fig. 3 shows an exploded perspective view of the water tank 8 according to a second embodiment.
  • the water tank 8 is composed of two parts, a shell 1 1 and a flat lid 12.
  • the shell 1 1 has a flat, parallel to the lid 12 bottom 13 and extending around the bottom 13 narrow wall 14, a the lid 12th facing planar frame 15 carries.
  • the lid 12 is tightly secured in the assembled state by gluing, ultrasonic welding or the like.
  • the cover 12 and the bottom 13 are parallel to the rear wall of the niche 4.
  • An inlet port 16 for connection to the conduit 9 and an outlet port 17 for connection to the conduit 7, each in the form of a pipe stub protruding integrally from the wall 14, are each arranged in an upper region of the tank 8 in the installation orientation.
  • the interior of the water tank 8 is divided into multiple by projecting from the bottom 13 and the peripheral wall 14 of the shell 1 1 slats.
  • a first such fin 18 extends adjacent to the outlet port 17 from an upper portion 19 of the wall 14 in the vertical direction to near an opposite lower wall portion 20 and thus separates a riser 21 from the rest of the interior of the tank 8.
  • This remainder is divided approximately in half into an upper mixing region 22 and a lower laminar flow region 23. While the mixing region 22 is largely composed of lamellae In the laminar flow area 23, many louvers 24 each extend alternately from the vertical louver 18 and a vertical portion 25 of the wall 14 in opposite directions, thus forcing a substantially zigzag, low-lint flow of the water through the area 23.
  • a horizontal fin 26 is arranged to guide inflowing water and to excite a counter-clockwise vortex flow in the mixing area 22.
  • a Lammelle 27 projecting from below into the mixing region 22 forms an obstacle to this vortex flow, are excited at the clockwise vortex, which provide for effective mixing of inflowing, warm water with already in the mixing region 22 befindlichem, cooled water.
  • the bottom 13 of the tank is not exactly rectangular, but trapezoidal, such that in the installed position, the lower wall portion 20 extends horizontally, the upper wall portion 19, however, slightly increases towards the outlet 17 conclusion.
  • a passage opening 28 is formed directly adjacent to the wall portion 19, whose free cross-section is substantially smaller than that of the riser 21 and of the fins 24 of the Laminarströmungs Schemes 23 limited line sections, so that when tapping water, the water flow through the Through hole 28 is small compared to the amount of water flowing through the laminar flow 23 and the temperature of the tapped water has no significant effect.
  • each blade 24 is an open towards the lid 12 notch formed, which, when the lid 12 is mounted on the shell 1 1, together with this defines a through hole 39.
  • these through-holes 39 when trapped in the tank, allow the air trapped in the tank 8 to rise or drain down when trapped. By applying pressure to the inlet port 16 with compressed air, this water can be expelled via the riser 21 and the outlet port 17.
  • the columns 29 may each have a closed end face which is fixed to the lid 12 in the same way as the frame 15 to prevent or at least limit deformation of the tank 8 under the pressure of the water contained therein.
  • the pillars 29 are hollow, as shown in the section of Fig. 4, and have an end opening 30 which is aligned with a respective corresponding opening 31 of the lid 12 to receive a rivet 32.
  • the modified embodiment of the shell 1 1 shown in FIG. 5 differs from that of FIG. 3 in that the through-openings 39 each have the form of narrow slits which extend over the entire width of the slats 24. Ie. the blades 24 are connected in this variant, neither with the vertical blade 18 nor with the side wall 35 of the shell 1 1, but only with the bottom 13. Die
