Definitions

  • the present invention relates to a refrigerator unit and/or a freezer unit having at least one refrigerated inner space and having at least one thermoelectric element, in particular having at least one Peltier element that is arranged such that the inner space can be cooled by the thermoelectric element.
  • the saturation vapor pressure drops due to the cooling of the air, which has the result that moisture from the air condenses at the cold surfaces of the refrigerated inner space.
  • the condensed water is collected due to the configuration of the refrigeration system and is led to the outside by a drainage channel or the like. It is collected in a condensation tray there which can be located above the compressor. The water in the condensation tray evaporates due to the waste heat of the compressor.
  • thermoelectric refrigerator unit or freezer unit For efficiency reasons, it is constructive in a thermoelectric refrigerator unit or freezer unit to keep the temperature difference at the heat pump much smaller than in a compression refrigeration machine. This has the result that no considerably colder surface is present in the refrigerated inner space at which the condensation takes place and that no location having a locally elevated temperature is present at the unit exterior which could be used for evaporating the condensation.
  • a refrigerator unit and/or freezer unit having the features of claim 1 .
  • Means are accordingly present for evaporating condensed water that have a heat exchanger located outside the refrigerated inner space.
  • heat exchanger is to be understood as any element that has a temperature that is sufficient for evaporating condensed water.
  • thermoelectric element is formed by the hot side of a thermoelectric element or by an element such as a metal body that is connected in a heat-transferring manner, in particular a thermoconductive manner, to the hot side of a thermoelectric element.
  • This thermoelectric element can simultaneously be arranged such that its cold side refrigerates the inner space of the unit.
  • thermoelectric element is operated at a constant capacity or at a capacity that is required for maintaining the temperature in the refrigerated inner space as constant and at least independently of the condensed water that results.
  • thermoelectric cooling for the collecting and leading off of the condensed water there is an apparatus for this purpose at a surface in the refrigerated inner space of the unit at which the lowest temperature is present due to the positioning of the thermoelectric cooling for the collecting and leading off of the condensed water.
  • the latter is led out of the unit and moves into a collection tray that is arranged, for example, around a region of the outer skin at which an elevated temperature is present.
  • This procedure can be sufficient for moderate climate conditions.
  • the incurred moisture quantity can be so large that, on the one hand, the condensation no longer takes place locally at the coldest point due to the small temperature spread, i.e. the small temperature gradient, in the inner space. It is a further problem that the temperature at the evaporation region is not high enough to evaporate the total condensed water.
  • a control or regulation unit is present for carrying out one or more condensation cycles.
  • This unit is configured such that it increases the temperature spread for the purpose of condensation and/or evaporation during a condensation cycle.
  • thermoelectric element e.g. of a thermoelectric element
  • the condensation cycle can be carried out at specific, optionally regular, time intervals or can depend on one or more parameters.
  • a parameter is, for example, the humidity and/or the quantity of formed condensed water.
  • At least one condensate surface is present in the refrigerated inner scape whose temperature is below that of other surfaces in the refrigerated inner space so that condensate is formed at the condensate surface.
  • the condensate surface can be formed by at least one thermoelectric element. It can in this respect be a thermoelectric element that is anyway used for refrigerating the refrigerated inner space or also a thermoelectric element especially used for the condensate formation.
  • thermoelectric element used especially for the condensate formation can be arranged such that it emits its waste heat to the refrigerated inner space.
  • the element can thus work very efficiently and can be operated at minimal capacity.
  • the cold generation and the condensate formation are effectively decoupled by this additional thermoelectric element so that the framework conditions of cold generation do not have to be considered in the design of the condensation geometry.
  • a detection means is present for detecting the opening of the closing element of the unit and that the control or regulation unit is designed for cyclic cooling such that it is operated in dependence on the detected opening.
  • An embodiment of the invention can thus comprise always initiating the condensation cycle after a door opening, i.e. when the door or another closing element is closed again, guiding the hot air newly moved in over the condensation point.
  • a fan that is arranged such that it circulates the air located in the refrigerated inner space.
  • At least one fan can be provided in the evaporation region to promote the evaporation rate.
  • At least one outflow element can be provided by which condensed water is transported to the means for evaporation, with provision preferably being made that the outflow element is dimensioned such that the transport of the condensed water takes place by capillary forces.
  • the outflow element is arranged such that the condensed water simply flows out of the refrigerated inner space due to gravity.
  • the evaporation is to be aimed for at other points such as at the top of the unit, provision can be made to conduct the condensed water that arises via capillary forces to a specific evaporation point or evaporation region such as the unit top.

  • the full vacuum insulation is preferably formed by one or more vacuum insulation bodies that have said film, the region surrounded by the film and the core material located therein.
  • a further thermal insulation by an insulating foam and/or by vacuum insulation panels or by another means for thermal insulation between the inside and the outside of the unit is preferably not provided.
  • This preferred form of thermal insulation in the form of a full vacuum system can extend between the wall bounding the inner space and the outer skin of the carcass and/or between the inner side and the outer side of the closing element such as a door, flap, lid, or the like.
  • the full vacuum system can be obtained such that an envelope of a gas-tight film is filled with a core material and is subsequently sealed in a gas-tight manner.
  • both the filling and the vacuum-tight sealing of the envelope take place at normal or ambient pressure.
  • the evacuation then takes place by the connection to a vacuum pump of a suitable interface worked into the envelope, for example an evacuation stub which can have a valve.
  • Normal or ambient pressure is preferably present outside the envelope during the evacuation.
  • a vacuum chamber can be dispensed with in an embodiment to this extent during the manufacture of the vacuum insulation.
  • the envelope preferably comprises a high barrier film or is a high barrier film which terminates the vacuum one formed by the envelope in a vacuum-tight manner.

  • the increase in the thermal conductivity of the vacuum insulation body caused by gas input is preferably ⁇ 100%, and particularly preferably ⁇ 50%, over its service life.
  • the surface-specific gas permeation rate of the envelope or of the connection or of the high barrier film is preferably ⁇ 10 ⁇ 5 mbar*I/s*m 2 and particularly preferably ⁇ 10 ⁇ 6 mbar*I/s*m 2 (measured according to ASTM D-3985).
  • This gas permeation rate applies to nitrogen and to oxygen.
  • the aforesaid small increases in the thermal conductivity are preferably achieved by these small gas permeation rates.
  • An enveloping system known from the sector of vacuum panels are so-called high barrier films.
  • Single-layer or multilayer films (which are preferably able to be sealed) having one or more barrier layers (typically metal layers or oxide layers, with aluminum and an aluminum oxide preferably being used as the metal or oxide respectively) are preferably understood by this within the framework of the present invention which satisfy the above-named demands (increase in thermal conductivity and/or surface-specific gas permeation rate) as a barrier to the gas input.
  • thermoelectric units The idea of introducing a thermoelectric element into the refrigerated inner space in order to form a condensate surface in this manner is not restricted to thermoelectric units.
  • the invention thus furthermore relates to any desired refrigerator unit and/or freezer unit having a refrigerated inner space and having a thermoelectric element introduced thereto, wherein a control or regulation unit is provided which controls the thermoelectric element such that it forms a condensate surface.
  • the condensate surface is preferably colder than adjacent surfaces or the coldest surface in the refrigerated inner space.
