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.
- Such a tank is usually mounted embedded on the inside of a housing wall of the refrigerator or in an insulating layer of the wall.
- the object of the invention is to provide a refrigeration device in which on the one hand ensures that a most practical needs satisfying amount of well-cooled, not heated by fresh nachgeströmtes water water can be tapped, and avoided on the other hand, an abrupt increase in water temperature when a tank has been completely tapped.
- the object is achieved in that in a refrigeration device with a water tank, the one inlet connection and one connected to a water dispenser Outlet port, the tank is divided into a mixing region and a laminar flow region, which are connected in series.
- the mixing area is adjacent the inlet port and the laminar flow area is adjacent to the outlet port, so that fresh incoming fresh water first mixes with already cooled water in the mixing area before entering the laminar flow area and finally discharging.
- an increase in temperature of the tapped water only gradually begins when a volume corresponding to the volume of the laminar flow area has been tapped off.
- the laminar flow area is preferably formed by a conduit guided in a detour between the mixing area and the inlet or outlet port of the tank.
- the line of the laminar flow area is bounded by louvers projecting from outer walls of the tank into its interior.
- 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.
- An outlet of the mixing area is preferably located at the bottom thereof, so that water which has cooled down on the outer walls of the mixing area and thereby dropped is first discharged.
- an outlet port is preferably placed at a highest point of the water tank.
- a vent expediently connects the highest point of the mixing area with the outlet port, so that, even if its outlet is at the bottom, a trouble-free venting is ensured for this.
- the water tank is preferably embedded in a housing wall of the refrigeration device.
- FIG. 1 shows a schematic section through an inventive refrigeration device.
- Figure 2 is a perspective exploded view of a water tank of the refrigerator.
- Fig. 3 shows a detail of the water tank in section.
- 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 Therefore, the condenser mounted generally outside on the rear wall of the body 1 can not be excluded.
- Fig. 2 shows an exploded perspective view of the water tank 8.
- 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 one around the Floor 13 extending narrow wall 14 which carries a cover 12 facing the planar frame 15.
- 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 roughly divided into an upper mixing region 22 and a lower laminar flow region 23. While the mixing region 22 is largely free of fins, in the laminar flow region 23 many fins 24 extend alternately from the vertical fins 18 and a vertical portion 25, respectively Wall 14 in opposite directions and thus force a substantially zigzag, low-vortex flow of water through the area 23rd
- a horizontal fin 26 is arranged to guide inflowing water and to excite a counter-clockwise vortex flow in the mixing area 22.
- a projecting from below into the mixing region 22 Lammelle 27 forms an obstacle to this vortex flow are excited to the vortex in a clockwise direction, which is effective for Mixing of inflowing, warm water with already in the mixing area 22 befindlichem, provide 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.
- the passage opening 28 of the air initially contained in the mixing area 22 makes it possible to reach the outlet port 17 and to escape from the tank.
- 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. 3, and have an end opening 30 which is aligned with a corresponding opening 31 of the lid 12 to receive a rivet 32.
