Definitions

  • the present invention relates to a condensate evaporator and a refrigeration device, which is equipped with a condensation water evaporator to eliminate condensation, which accumulates during operation of the refrigeration device to the evaporator.
  • a gutter or bowl that collects effluent from the evaporator condensate, and which is connected via a bore in the body of the refrigerator with an outside attached evaporation tray, run in the condensate and in it can evaporate.
  • the evaporation tray is usually mounted on a compressor of the refrigerator to heat the condensate in the evaporation tray with the waste heat generated during operation of the compressor and thus to accelerate its evaporation.
  • a terraced evaporation tray The base of such a terraced shell is divided by partitions into several basins, which are at the level of the shell bottom differ.
  • the condensation water is first supplied to a highest basin and only when it is filled to the edge of its partitions, water can flow from there into adjacent, lower-lying basin.
  • the effect of the terracing is that in each basin, the water depth can be kept low, so that the available heating power only a small amount of water, but this to a higher temperature than in the case of a non-terraced evaporation tray, where the water depth in places can be much larger.
  • the high temperature causes efficient evaporation.
  • the free water surface at which evaporation can take place is no greater in a terraced shell than in a non-terraced shell.
  • condensation water evaporator with a shell for receiving the condensation water, in which above the shell and from this by a
  • Air space spaced at least one buffer for the condensation water is arranged, which stores the condensation water with exposed water surface. So already in the
  • Cache evaporates, reaches the shell. Evaporation in the shell is due to the air space between it and the cache not or at least not significantly limited.
  • the buffer comprises a second shell.
  • the second shell preferably has an overflow vertically spaced from its bottom, the distance of the overflow from the bottom defining the maximum water level in the second shell. This is preferably at most a few millimeters.
  • the buffer comprises a plate which is provided with a surface contour storing the condensation water by capillary action. It is possible to combine both embodiments in that the plate of the second embodiment is formed by the bottom of the second shell according to the first embodiment and the surface contour storing the condensation water is formed on the underside of the bottom. So not only the top of the second shell is available to evaporate condensate, but also their bottom.
  • the plate is provided with at least one passage for the condensed water, and the surface contour comprises at least one outgoing from the passage groove, which is by capillary action able to lead the condensate water to the passageway or from it.
  • the passage may in particular be realized as a bore running through the plate or as a notch formed on the edge of the plate.
  • the invention also provides a refrigeration device that is configured with a condensation water evaporator of the type described above.
  • a condensation water evaporator is preferably arranged on a compressor of the refrigeration device in order to use its waste heat efficiently. If the refrigeration device is equipped with a blower, then it is also expedient if the condensate evaporator is arranged on the way of an air flow generated by the blower.
  • FIG. 1 shows a schematic section through an inventive refrigeration device.
  • FIG. 2 is a perspective exploded view of the condensation water evaporator of the refrigerator of FIG. 1;
  • FIG. 3 shows a modified embodiment of a second shell of the condensation water evaporator from FIG. 2;
  • FIG. 4 is a bottom view of the tray shown in FIG. 3; FIG. and - A -
  • Fig. 5 is a perspective view of a Tauwasser contain island for a condensation water evaporator according to another embodiment of the invention.
  • the refrigeration device shown schematically in section in FIG. 1 comprises a heat-insulating housing with a body 1 and a door 2 hinged thereto, which enclose an interior 3.
  • a chamber 6 is partitioned, in which a plate-shaped evaporator 5 is arranged.
  • the chamber 6 communicates with the interior 3 via openings 7 of the rear wall.
  • a refrigerant circuit extends from a high-pressure outlet of a compressor 8 via a condenser 9 mounted outside on the back of the body 1 and the evaporator 5 to a suction port of the compressor 8.
  • the compressor 8 is located in a ground-level niche 10 at the rear of the body 1 below the Evaporator 5 housed.
  • a (not shown) fan at one of the openings 7 drives an exchange of air between the interior 3 and the chamber 6, wherein atmospheric moisture from the interior 3 at the evaporator 5 precipitates.
  • the refrigerator is a refrigerator
  • the temperature of the evaporator 5 is always positive depending on the set temperature of the interior 3, or at least reaches positive values between two operating phases of the compressor 8, so that the moisture precipitating on the evaporator 5 is continuous can flow off or at least during a stance phase of the compressor 8, between two operating phases, can flow substantially, so that no larger amounts of moisture collect on the evaporator 5.
  • the temperature of the evaporator 5 during a stagnant phase of the compressor 8 is usually below 0 ° C, so that during many successive stance and operating phases of the compressor, the evaporator 5 gradually iced.
  • a (not shown) heater is arranged on the evaporator 5, which allows during a stance phase of the compressor 8 to heat the evaporator to temperatures above 0 ° C and to bring the condensate to drain.
  • the condensation accumulates in one and the other case in a groove 1 1 at the bottom of the chamber 6, from the lowest point of a pipe 12 goes out.
  • This pipeline passes through the insulating layer of the body 1 to a storage volume for the condensate forming shell 13 and, via an overflow 14 of the shell 13, in an evaporation tray 15 which is mounted on the compressor 8 in close thermal contact therewith.
  • FIG. 2 shows an exploded perspective view of the shell 13 and the evaporation tray 15.
  • the evaporation tray 15 is divided by web-shaped partitions 16 into a plurality of basins 18 to 23, wherein the limited by the lowest partitions pool 18 is located at the highest point of the bottom of the evaporation tray 15. This point corresponds to the apex of the compressor 8, which engages in the evaporation tray from below, and is subjected to the greatest heat flow from the compressor under each basin per unit of its base area.
  • the basins communicate with each other by flat cutouts 17 on the upper edges of the intermediate walls 16, so that whenever a basin is filled to overflow, is flooded by such a cutout 17 the next.
  • the base of the shell 13 corresponds in the embodiment shown here, the combined base of the basin 18, 19, 20, 21 of the evaporation tray 15.
  • the shell 13 is supported by means of integrally molded support columns 24 to the evaporation tray 15.
  • the support columns 24 each have at their lower end a slot 25 which is provided in order to be plugged onto the dividing walls 16 surrounding the basins 18 to 21.
  • the tip of a rising from the bottom of the shell 13 pipe socket 26 forms an overflow. If the water level in the shell 13 exceeds the level of the overflow 14, water flows down through the pipe socket 26.
  • the pipe socket 26 is extended a little way beyond the bottom of the shell 13, to ensure that overflowing water dripping only from the lower end of the pipe socket 26 directly into the highest basin 18 of the evaporation tray 15 and not at the Flows along the bottom of the shell 13, then dripping into one of the lower-lying pool.
  • a second embodiment of the shell 13 is shown in Fig. 3 in a perspective view.
  • the overflow 14 is not formed here by a central pipe socket, but by a notch 27 in a side wall of the shell, which opens onto a vertical groove 28 on the outside of the shell 13. About the notch 27 and the groove 28 reaches overflowing condensation on the bottom of the shell 13. This bottom is shown in Fig. 4 in a perspective view.
  • a plurality of grooves 29 each extend from the groove 28 to a drip tap 30 which protrudes from the bottom at a central location of the shell 13, above the basin 18. From the shell 13 overflowing water is held in this way at the bottom of the shell 13 by capillary force in the grooves 29.
  • the grooves 29, which fill the entire bottom of the shell 13, are able to store a considerable amount of water, so that the overflowing from the shell 13 thawing water remains for a long time at the bottom of the shell 13 before it reaches the drip 30 and dripped into the basin 18.
  • Even a considerable amount of the condensation water can evaporate even before it reaches the evaporation tray 15.
  • the bottom of the shell 13 is slightly sloping from the edges where the grooves 28 are formed to a center line 31 to ensure that the water in grooves 29 to the arranged on the center line 31 drip tray 30 flows when the capacity of the grooves 29 is exhausted, and not at any point on the underside of the shell 13 drops that could fall into pools other than the pool 18.
  • the shell 13 is replaced by a storage plate 32 shown in a perspective view in FIG. 5.
  • the base of the storage plate 32 is here the same as in the shell 13, and also it is held by attached to the partitions 16 support columns 24 to the evaporation tray 15.
  • Dew water dripping from the pipe 12 onto the storage disk 32 is distributed in a system of grooves 29 formed at the top of the storage disk 32 and reaches via these two grooves 28 on the edge of the storage disk 32, over which the condensation water as in the shell of Figs. 3 and 4 to the underside of the storage disk 32 passes.
  • This is also provided with a system of grooves 29 and a central drip 30, as shown in FIG.
  • the remarkable thing about the storage disk 32 is that it provides a large evaporation surface with minimal height. Since she does not like the shell has 13 side walls, it provides a horizontal air flow only a very low flow resistance. It is therefore particularly suitable for use in a refrigeration device, in which a (not shown) fan drives a flow of air that sweeps along the free water surfaces of the evaporator.
  • the cache is located, i. H. the shell 13 or the storage plate 32, each completely above the base of the evaporation tray 15. This generally allows a compact design of the evaporator. Depending on the installation space available for the evaporator, however, it may also be expedient if the bases of the evaporation tray 15 and the intermediate storage 13 or 32 do not completely overlap, provided that it is only ensured that excess water passes from the intermediate storage into the evaporation tray 15.
