Definitions

  • the invention relates to a cooling container with a dimensionally stable bottom part and an inflatable structure connected to it with a side wall and a lid, the side wall and the lid each having an inner and an outer wall with intermediate transverse walls, the transverse walls being spaced apart Air passage openings are provided, at least one valve is provided for filling or emptying the space between the inner and outer wall and a cooling unit is arranged on the bottom part.
  • a well-known cooling container of this type (CH-PS 555 269) is inflatable or collapsible, but nothing more emerges from the aforementioned CH-PS 555 269 about the type and arrangement of the actual cooling unit than that a plate-shaped unit with leading to the outside Feed lines can be provided on the inside of the floor.
  • the FR-PS 2 435 680 shows a dimensionally stable cool box, in the lid of which is housed a thermoelectric cooler that can act as a heater by reversing the polarity.
  • DE-OS 26 21 844 shows an inflatable cooling container with a base plate. Outside the container, a chiller is obviously provided (the description is hardly understandable in this regard), which rests on a tripod.
  • the US-PS 3 986 337 shows a kind of "hot plate” for laboratory purposes, which can also serve as a “cooling plate”.
  • the heating or cooling takes place by means of thermoelectric elements and the switching from cooling to heating by reversing the polarity of the current flow.
  • a fan is provided for cooling the elements.
  • the US-PS 4 242 874 discloses - comparable to the above-mentioned FR-PS 24 35 680 - a unit containing Peltier elements and a blower, which can be used as a lid of a cool box.
  • the aim of the invention is to provide an active cooling container which, when not in use, is small in size and therefore light, e.g. in a luggage, can be accommodated.
  • a good cooling effect should result with low weight.
  • the bottom part has an upper plate made of a good heat-conducting material, preferably made of aluminum, to which a Peltier element is connected in a heat-conducting manner, the plate on its underside with a heat-insulating layer, preferably made of foam plastic is provided and in the bottom part a cooling fan or the like. is provided for the Peltier element.
  • the heat-conducting plate which is thermally insulated on its underside, with a Peltier element and the resulting separation of a lower floor area from the actual cooling area, a good cooling effect results in practice with a low weight of the entire arrangement.
  • an electric motor is provided, on the shaft of which two impellers or the like. are arranged, an impeller for air circulation in the Neren of the structure and an impeller for cooling the Peltier element is below the plate.
  • the entire structure can be inflated or deflated using a single valve.
  • the cooling container according to the invention consists of a dimensionally stable bottom part 1, e.g. from a plastic tub, and from an inflatable structure 2 connected or connectable to it. In all figures, this structure 2 is shown in the inflated state.
  • the structure 2 has a side wall 3, which in the present case shows a square cross-sectional shape, so that the entire container in principle represents a hollow square prism.
  • the container can also have, for example, a round or elliptical cross section, have a bulbous shape, etc.
  • the inner wall 4, the outer wall 5 and the transverse walls 6 are made of flexible plastic.
  • a valve 8 is provided on the outer wall 5, via which the cavity between the inner and outer walls can be filled or emptied with air.
  • the Be tenwandung 3 is thus inflatable or can be folded to a small size after opening the valve 8.
  • the transverse walls 6 have a stabilizing and convection-inhibiting effect, but the air passage openings 7 allow air to pass through when filling and emptying.
  • the transverse walls 6 do not have to run in the vertical direction, as shown, they can also be arranged horizontally or inclined, and it is also possible to provide transverse walls which run at an angle to one another, in particular at right angles.
  • the structure 2 also has a cover 9 which, in the example shown, is constructed in the same way as the side wall 3, i.e. it has an inner wall 4 ', an outer wall 5', transverse walls 6 'with air openings 7' and a valve 8 '.
  • the lid 9 can also be inflated or folded or rolled.
  • the lid 9 can be completely removable or, e.g. 5, can be connected to the side wall 3 in a hinge-like manner via a flexible plastic sheet 10.
  • the cover 9 can have an overhanging edge 12 which bears against the upper edges of the side wall 3.
  • both the side wall 3 and the cover 9 have in addition to the inner and outer walls 4, 4 'and 5, 5' also end walls 13, 13 '.
  • the cooling container according to the invention has an active cooling system, which is described below.
  • the bottom part 1 has an upper plate 14 made of a good heat-conducting material, preferably of aluminum.
  • This plate 14 forms the lower boundary of the interior of the structure 2, ie the actual cooling room, in which, for example, food and drinks can be introduced.
  • On the plate 14 there is a Peltier element 15, the electrical connections of which are connected to an electrical plug fastened to the wall of the base part 1 direction 16 is connected.
  • the Peltier element 15 is also provided with a cooling plate 17, cooling fins or the like. Mistake.
  • a heat-insulating layer 18, for example made of hard foam plastic, is glued to the underside of the plate 14.
  • a small electric motor 19 is provided in the base part 1, the axis 20 of which is directed upwards, through an unspecified hole in the plate 14, in order on the one hand to forcibly circulate air inside the structure, and on the other hand to enable forced cooling of the cooling plate 17 of the Peltier element and the insulating layer 18 extends into the interior of the structure 2.
  • a first impeller 21 sits on the axis 20, which, as indicated by arrows in FIG. 5, sucks in outside air, leads it over the cooling plate 17 and finally pushes the heated air out again.
  • guide surfaces 22 are provided, which are only indicated schematically.
  • Corresponding air supply or outlet openings 23, 24 are also provided in the base part 1.
  • the shaft or axis 20 can be extended through the layer 18 and the plate 14 into the interior of the cooling container and be provided there with a second impeller 25, which circulates the air, so that the formation a cold air lake above the plate 14 is avoided.
  • the second impeller 26 is expediently covered by a protective cover 26, e.g. a sieve or perforated sheet.
  • the lid of the cooling container can also be rigid, ie not inflatable, and in this case advantageously consists of an upper solid plastic plate which is connected to a lower insulating plate made of foamed plastic. If the edge of the bottom part 1 over the upper plate 14 is pulled up, the structure 2 can be folded into the upper part of the bottom part after the blown air has been emptied, the lid then closing the bottom part upwards, so that the container assumes a compact, pleasing shape when folded, whereby the inflatable structure is protected against damage.
