Description

Die Erfindung betrifft ein Kältegerät, wie ein Nofrost-Kühl- oder -Gefriergerät oder dergleichen, mit einem wärmeisolierenden Gehäuse, innerhalb welchem wenigstens ein durch einen Ventilator mit Kaltluft beaufschlagter Lagerraum zur Aufnahme von Lagergut und ein zur Aufnahme eines selbsttätig abtauenden Verdampfers dienender Verdampfer vorgesehen ist, welcher vom Lagerraum durch eine Trennplatte weitestgehend abgeteilt ist, wobei die Trennplatte verdampferseitig eine als Abdeckung dienende Tauwasserauffangschale aufweist, die mit einer anhand einer elektrischen Widerstandsheizung beheizbaren Tauwasserablaufrinne versehen ist und die zusammen mit der Tauwasserablaufrinne in eine Fließstrecke für das beim Abtauen des Verdampfers anfallende Tauwasser bildet, wobei die Abdeckung und die Tauwasserablaufrinne aus metallischem Werkstoff gebildet sind und die Heizung außerhalb der Fließstrecke liegt.The invention relates to a refrigerator, such as a Nofrost refrigerator or freezer or the like, with a heat-insulating housing, within which at least one through a fan with cold air acted upon storeroom for receiving stored goods and provided for receiving an automatically defrosting evaporator serving evaporator is which of the storage room by a partition plate as far as possible is divided, wherein the partition plate on the evaporator side serving as a cover condensate collecting tray having, which can be heated with an electric resistance heating Dew water drainage channel is provided and which together with the condensation water drainage channel in forms a flow path for the defrosting of the evaporator resulting condensation water, wherein the Cover and the condensation drainage channel are formed from metallic material and the heating is outside the flow line.

Aus der US-A-5 255 536 ist ein Nofrostkältegerät mit einem Gefrierfach und einem Kühlfach bekannt, wobei zwischen dem Kühlfach und den Gefrierfach eine wärmeisolierende Trennwand mit einem Aufnahmeraum vorgesehen ist, in dem ein Verdampfer angeordnet ist. Der Verdampfer ist an seiner Unterseite mit einer Heizplatte ausgestattet, die mit einer elektrischen Widerstandsheizung im wärmeleitenden Kontakt steht, wobei die Widerstandsheizung zwischen der Heizplatte und einer Wärmeisolierplatte angeordnet ist, die dazu dient, die Oberseite der wärmeisolierenden Trennplatte von der Heizeinnchtung partiell abzuschirmen.From US-A-5 255 536 is a Nofrostkältegerät with a freezer and a refrigerator compartment known, between the refrigerator compartment and the freezer a heat-insulating Partition is provided with a receiving space in which an evaporator arranged is. The evaporator is equipped on its underside with a heating plate, which with a electrical resistance heating is in heat-conducting contact, wherein the resistance heating is disposed between the heating plate and a heat insulating plate, the this serves to partially shield the top of the heat-insulating separator plate from the heater shield.

Dieser Stand der Technik ist dahingehend nachteilig, dass zur Ausbildung der Tauwasserauffangschale in der Trennplatte eine Mehrzahl zusätzlicher Bauelemente zum Einsatz kommt, denn neben der eigentlichen Trennplatte ist eine gesonderte Tauwasserauffangschale in Form der Heizplatte und ein weiteres zusätzliches Bauelement nämlich eine Isolierplatte erforderlich, um die Heizung von der Oberseite der Trennplatte partiell abzuschirmen. Die Oberseite der Trennplatte bildende Deckschicht ist neben ihrer Abdeckfunktion für das wärmeisolierende Material in der Trennplatte ungenutzt.This prior art is disadvantageous in that the formation of the condensate drip tray in the partition plate a plurality of additional components are used comes, because in addition to the actual partition plate is a separate dewwater collection tray in the form of the heating plate and another additional component namely a Insulating plate required to partially shield the heater from the top of the separator plate. The top of the partition plate forming cover layer is in addition to their covering function unused for the heat-insulating material in the partition plate.

Weiterhin ist bei Nofrostkäftegeräten, beispielsweise Nofrostgefrierschränken, bekannt dass diese neben ihrem Gefrierraum einen davon getrennten Raum zur Unterbringung eines üblicherweise bei Nofrostgeräten zum Einsatz kommenden mit einer Abtauheizung ausgestatteten Lamellenverdampfers aufweisen. Zur Trennung zwischen dem Gefrierraum und dem Verdampferraum kommt bei bekannten Geräten eine auch wärmeisolierend ausgeführte Trennplatte zum Einsatz, deren dem Verdampfer zugewandte Oberseite zugleich als Tauwasserauffangschale ausgebildet ist. Die nach dem Stand der Technik hergestellten Trennplatten weisen üblicherweise ein schalenförmig ausgebildetes Kunststoffunterteil, eine Wärmeisoliationsschicht und ein mit dem Kunststoffunterteil beispielsweise schweißtechnisch verbundenes Kunststoffabdeckteil auf. Dieses bildet zusammen mit dem Kunststoffunterteil ein die Wärmeisoliationsschicht aufnehmendes kastenförmiges Gehäuse, welches an seiner dem Verdampfer zugewandten Außenseite als Tauwasserschale ausgebildet ist, an welcher eine in eine Tauwasserablaufleitung übergeführte Tauwasserablaufrinne angeordnet ist. Ferner ist das Abdeckteil im Bereich des Verdampfers mit einer aus Aluminium gefertigten Wärmeleitplatte versehen, welche in wärmeleitenden Kontakt mit der Abtauheizung des Verdampfers gebracht ist, um ein sicheres Abfließen des Schmelzwassers während der Abtauphase des Verdampfers in dessen Bereich zu gewährleisten. Femer ist im Bereich der Tauwasserablaufrinne eine verdampferseitig auf das Kunststoffabdeckteil aufgeklebte elektrische Widerstandsheizung vorgesehen, um ein vollständiges Abfließen des vom Verdampfer während seiner Abtauphase abtropfenden Schmelzwassers in die Tauwasserablaufleitung zu erreichen. Durch die Anordnung der elektrischen Widerstandsheizung auf dem Abdeckteil werden bei den bekannten Geräten Rüdchaltestufen für das abfließende Schmetzwasser gebildet, so dass Schmelzwasserreste im Bereich der Ablaufrinne zurückgehalten wurden, welche bei erneutem Kühlbetrieb des Verdampfers ausfrieren. Die sich in diesem Bereich bildenden Eisansammlungen können dabei unter ungünstigen Umständen nicht nur die Tauwasserablaufrinne verschließen sondern bis hin zum Verdampfer anwachsen und in dessen Lamellen ragen, wodurch die zwangsweise Belüftung des Verdampfers und somit die bestimmungsgemäße Kühlung zumindest behindert wenn nicht sogar unterbunden wird. Derartige Vorfälle führten entweder zu drastischen Leistungseinbußen des Gerätes oder aber zu einem völligen Funktionsausfall.Furthermore, in Nofrostkäftegeräten, such as Nofrostgefrierschränken known that this next to their freezer a separate room for accommodation a commonly used in Nofrostgeräten with a defrost heater equipped lamellar evaporator have. For separation between the freezer compartment and the evaporator room is also a heat-insulating in known devices running partition plate used, the evaporator facing top at the same time designed as a condensation water collection tray. The according to the prior art produced separating plates usually have a cup-shaped plastic lower part, a Wärmeisoliationsschicht and with the plastic lower part, for example welding technically connected plastic cover on. This makes up together with the plastic base a heat insulating layer receiving box-shaped Housing, which on its side facing the evaporator as a condensation water bowl is formed, at which one in a condensation water discharge line transferred Condensation drainage channel is arranged. Furthermore, the cover part is in the region of the evaporator provided with a made of aluminum heat conducting plate, which in heat-conducting Contact with the defrost heater of the evaporator is brought to a safe drain the melt water during the defrosting of the evaporator in the area to ensure. Furthermore, there is an evaporator side in the area of the condensation drainage channel provided on the Kunststoffabdeckteil glued electrical resistance heating, to completely drain the evaporator during its defrosting phase to reach dripping melt water in the condensate drain line. By the Arrangement of the electrical resistance heater on the cover are in the known Devices Rüdchaltestufen formed for the effluent Schmetzwasser, so that Meltwater residues were retained in the gutter, which at renewed Freeze cooling operation of the evaporator. Which are forming in this area Ice accumulation can under unfavorable circumstances not only the condensation water drainage channel but close to the evaporator grow and in the Slats protrude, causing the forced ventilation of the evaporator and thus the intended Cooling at least impeded if not prevented. Such incidents either led to drastic power losses of the device or but to a complete functional failure.

Darüber hinaus ist durch den Einsatz von metallischen, gute Wärmeleiteigenschaften aufweisenden Werkstoffen einerseits die Tauwasserablaufrinne mit dem ihr zugeordneten Zulauf ausreichend erwärmt und andererseits auch eine gleichmäßige, zumindest weitestgehend ganzflächige Erwärmung der Abdeckung durch die partiell auf sie einwirkende Abtauheizung des Verdampfers erreicht.By the refrigeration device according to the invention is in the discharge area of the melt water creates a hindemisfreie flow path, so that the melt water both in Area of the cover as well as in the area of the condensation drainage channel unhindered can flow off and thus can not form meltwater residues, which Over time, dysfunctions on the refrigeration unit increase in the accumulation of ice being able to lead.
