Description

Kältegerät Refrigerator
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 Aggregate vorgesehen ist, welcher vom Lagerraum durch eine Trennplatte zumindest weitestgehend abgeteilt ist, wobei die Trennplatte verdampferseitig eine als Abdeckung dienende Tauwasserauffangschale aufweist, welche mit einer anhand einer Heizeinrichtung beheizbaren Ablaufrinne versehen ist.The invention relates to a refrigeration device, such as a Nofrost refrigerator or freezer or the like, with a heat-insulating housing, within which at least one storage space, which is supplied with cold air by a fan, is provided for accommodating stored goods and an assembly serving for accommodating an automatically defrosting evaporator , which is at least largely separated from the storage space by a partition plate, the partition plate on the evaporator side serving as a cover condensate drip tray, which is provided with a heating channel that can be heated by means of a heating device.
Nofrostkältegeräte, beispielsweise Nofrostgefrierschränke weisen neben ihrem Gefrierraum einen davon getrennten Raum zur Unterbringung eines üblicherweise bei Nofrostgeräten zum Einsatz kommenden mit einer Abtauheizung ausgestatteten Lamellenverdampfers auf. 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. Ferner 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 Tauwasser-ablaufleitung zu erreichen. Durch die Anordnung der elektrischen Widerstandsheizung auf dem Abdeckteil werden bei den bekannten Geräten Rückhaltestufen für das abfließende Schmelzwasser 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.In addition to their freezer compartment, no-frost refrigeration devices, for example no-frost freezers, have a separate room for accommodating a lamella evaporator which is normally used with no-frost devices and is equipped with a defrost heater. For separation between the freezer compartment and the evaporator compartment, a heat-insulating partition plate is used in known devices, the upper side of which faces the evaporator and is at the same time designed as a condensate collecting pan. The partition plates produced according to the prior art usually have a shell-shaped plastic lower part, a heat insulation layer and a plastic cover part, for example welded to the plastic lower part. Together with the plastic lower part, this forms a box-shaped housing which absorbs the heat insulation layer and is formed on its outside facing the evaporator as a condensation water tray, on which a condensation water discharge channel is arranged which is transferred into a condensation water discharge line. Furthermore, the cover part in the area of the evaporator is provided with a heat-conducting plate made of aluminum, which is brought into heat-conducting contact with the defrost heater of the evaporator in order to ensure that the melt water flows away during the defrosting phase of the evaporator in its area. Furthermore, in the area of Defrost water drainage channel is provided with an electrical resistance heater glued to the plastic cover part on the evaporator side in order to achieve a complete drainage of the melt water dripping from the evaporator during its defrosting phase into the condensation water discharge line. The arrangement of the electrical resistance heating on the cover part forms retention stages for the flowing melt water in the known devices, so that melt water residues have been retained in the region of the drainage channel, which freeze out when the evaporator is again cooled. Under unfavorable circumstances, the accumulation of ice that forms in this area can not only close the condensate drainage channel but also grow up to the evaporator and protrude into its fins, which at least impedes, if not prevents, the forced ventilation of the evaporator and thus the intended cooling. Such incidents either led to a drastic loss in performance of the device or to a complete loss of function.
Der Erfindung liegt die Aufgabe zugrunde, bei einem Kältegerät gemäß dem Oberbegriff des Anspruches 1 mit einfachen konstruktiven Maßnahmen die Nachteile des Standes der Technik zu vermeiden und dauerhaft ein Abfließen des beim Abtauvorgang des Verdampfers anfallenden Schmelzwassers zu gewährleisten.The invention has for its object to avoid the disadvantages of the prior art in a refrigeration device according to the preamble of claim 1 with simple design measures and to ensure permanent drainage of the melt water occurring during the defrosting of the evaporator.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Abdeckung aus metallischem Werkstoff gebildet ist und eine aus metallischem Werkstoff gefertigte Tauwasserablaufrinne aufweist und daß die Heizeinrichtung außerhalb der Fließstrecke des beim Abtauen des Verdampfers anfallenden Schmelzwassers liegt.This object is achieved according to the invention in that the cover is formed from a metallic material and has a condensate drainage channel made from a metallic material and that the heating device lies outside the flow path of the melt water which occurs when the evaporator is defrosted.
Hierdurch ist im Abflußbereich des Schmelzwassers eine hindernisfreie Fließstrecke erzeugt, so daß das Schmelzwasser sowohl im Bereich der Abdeckung als auch imThis creates an unobstructed flow path in the discharge area of the melt water, so that the melt water both in the area of the cover and in the
Bereich der Tauwasserablaufrinne ungehindert abfließen kann und sich somit keineArea of the condensate drainage channel can flow freely and therefore none
Schmelzwasserrückstände bilden können, welche im Laufe der Zeit zu Funktionsstörungen am Kältegerät anwachsenden Eisansammlungen führen können. 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.Melt water residues can form, which over time Malfunctions on the refrigerator can lead to the accumulation of ice. In addition, the use of metallic materials with good thermal conductivity properties on the one hand heats the condensate drainage channel with the associated inlet sufficiently and on the other hand also achieves a uniform, at least largely complete heating of the cover due to the partial defrost heating of the evaporator.
Besonders einfach aufgebaut und somit besonders rasch montierbar ist die Trennplatte, wenn nach einer bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß die Trennplatte ein schalenähnlich ausgebildetes Tragteil aufweist, welches mit der Abdeckung zu einem mit aufschäumenden Wärmeisolationsmaterial verfüllten Gehäuse zusammengefügt ist. Durch die adhäsive Wirkung des Wärmeisolationsmaterials ist das Tragteil und die Abdeckung, ohne zusätzliche Verbindungsmittel verwenden zu müssen, zu einer formstabilen Baueinheit verbunden.The partition plate is particularly simple and can therefore be assembled particularly quickly if, according to a preferred embodiment of the object of the invention, it is provided that the partition plate has a shell-like supporting part which is joined to the cover to form a housing filled with foaming heat insulation material. Due to the adhesive effect of the thermal insulation material, the supporting part and the cover are connected to a dimensionally stable unit without having to use additional connecting means.
Besonders einfach gestaltet sich die Montage einer Trennplatte mit einem aus Kunststoff-Spritzguß gefertigten Trennplattenunterteil, wenn nach einer bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß die Abdeckung und die Tauwasserablaufrinne einstückig miteinander verbunden sind und die Tauwasserauffangschale bilden. Darüber hinaus ist durch die Einstückigkeit eine besonders gleichmäßige Erwärmung sowohl der Abdeckung als auch der daran angeformten Tauwasserablaufrinne erreichbar.The assembly of a separating plate with a separating plate lower part made of plastic injection molding is particularly simple if, according to a preferred embodiment of the object of the invention, it is provided that the cover and the defrosting water gutter are integrally connected to one another and form the defrosting water collecting tray. In addition, particularly uniform heating of both the cover and the condensation drainage channel formed thereon can be achieved due to the one-piece design.
Besonders toleranzgenau und gleichzeitig besonders günstig hinsichtlich des zur Ablaufrinne hin gerichteten Gefälles herstellbar ist eine Abdeckung samt der an sie angeformten Tauwasserablaufrinne, wenn nach einer nächsten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß die Abdeckung und die Tauwasserablaufrinne durch spanlose Formgebung erzeugt ist. Hierbei kann neben Spritzgießen von gießfähigen metallischen Werkstoffen wie beispielsweise Aluminium oder dergleichen auch die Verformung einer Platine aus metallischem Werkstoff wie beispielsweise einer Aluminiumplatine durch Tiefziehen Anwendung finden, wobei die durch Tiefziehen hergestellte Abdeckung Kostenvorteile aufweist.A cover, together with the condensation water gutter molded onto it, can be produced particularly precisely and at the same time, particularly inexpensively, with respect to the slope directed towards the drainage channel if, according to a next advantageous embodiment of the subject of the invention, it is provided that the cover and the condensation water drainage channel are produced by non-cutting shaping. In addition to injection molding of castable metallic materials such as for example aluminum or the like, the deformation of a plate made of metallic material such as an aluminum plate by deep drawing can be used, the cover produced by deep drawing having cost advantages.
Gemäß einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Tauwasserablaufrinne an ihrer vom Verdampfer abgewandten Unterseite mit der Heizeinrichtung versehen ist.According to a further preferred embodiment of the object of the invention, it is provided that the condensate drainage channel is provided with the heating device on its underside facing away from the evaporator.
Durch eine derartige Anordnung der Heizeinrichtung ist diese vor ungewollten Beschädigungen, zum Beispiel während des Fertigungsdurchlaufes des Kältegerätes geschützt. Darüber hinaus sind im Falle einer elektrischen Widerstandsheizung die Anschlußpole für den Widerstandsdraht nicht zugänglich. Außerdem ergibt sich durch die wärmeisolationsseitige Anordnung der Heizeinrichtung für die Tauwasserablauf rinne eine vollkommen hindernisfreie Oberfläche der Tauwasserauffangschale auf ihrer dem Verdampfer zugewandten Seite, insbesondere im Bereich der Tauwasserauffangschale zugleich kann die Heizeinrichtung zur besonders intensiven Erwärmung der Tauwasserablaufrinne an deren für die Eisansammlung kritischen Stellen angeordnet sein, ohne dabei ein Abflußhindernis für das während des Abtauvorgangs des Verdampfers anfallenden Schmelzwassers darzustellen.Such an arrangement of the heating device protects it from unwanted damage, for example during the production run of the refrigeration device. In addition, in the case of electrical resistance heating, the connection poles for the resistance wire are not accessible. In addition, the arrangement of the heating device for the condensation drainage channel on the heat insulation side results in a completely obstacle-free surface of the condensation water collecting tray on its side facing the evaporator, in particular in the area of the condensation water collecting tray at the same time, the heating device for particularly intensive heating of the condensation water drainage channel can be arranged at the points critical for the ice accumulation without being a drainage obstacle for the melt water that occurs during the defrosting of the evaporator.
Entsprechend einer nächsten bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Heizeinrichtung zwischen der Abdeckung mit der Tauwasserablaufrinne und einer der Wärmeisolation der Trennplatte zur Heizeinrichtung vorgelagerten Auflageebene angeordnet ist.According to a next preferred embodiment of the subject matter of the invention, it is provided that the heating device is arranged between the cover with the condensate drainage channel and a support plane upstream of the heat insulation of the separating plate from the heating device.
Hierdurch ist eine den einschlägigen VDE-Richtlinien besonders gerecht werdende Konstruktion für die Trennplatte bereitgestellt. Besonders zweckmäßig ausgebildet ist die Heizeinrichtung, wenn nach einer letzten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß die Heizeinrichtung als Rohrheizkörper ausgebildet ist.This provides a design for the partition plate that is particularly in line with the relevant VDE guidelines. The heating device is particularly expedient if, according to a last advantageous embodiment of the object of the invention, it is provided that the heating device is designed as a tubular heating element.
Die Erfindung ist in der nachfolgenden Beschreibung anhand eines in der beigefügten Zeichnung vereinfacht dargestellten Ausführungsbeispieles erläutert.The invention is explained in the following description with reference to an embodiment shown in simplified form in the accompanying drawing.

Der Gefrierraum 15 ist vom Verdampferraum 18 durch eine wärmeisolierend ausgeführte Trennplatte zum Teil wärmeisolierend abgetrennt, welche zugleich als Träger für den Lamelienverdampfer 19 dient.According to Figure 1, the upper section of a domestic freezer 10 is shown with a heat-insulating housing 11, which is equipped in its rear wall with a heat insulation penetrating and provided with an outward slope pipe socket 12, which is provided on a provided on the outside of the rear wall Water drain pipe 13 is connected. The heat-insulating housing 11 has, on its front side opposite the rear wall, a heat-insulating door 14 in the closed state, via which a freezer compartment 15 is accessible, which is divided into individual freezer compartments 16, which can be closed, for example, via a flap 17 that can be pivoted about a horizontal axis. To cool the freezer compartment 15, an evaporator compartment 18, which from time to time is used automatically, is used defrosting lamella evaporator 19, which is provided for the purpose of defrosting with an electrical resistance heater 20 guided in a protective tube and which is forced-ventilated by a fan 21, by means of which the freezer space 15 is acted upon by cooling air cooled by the evaporator 19. The freezer compartment 15 is partially insulated from the evaporator compartment 18 by a heat-insulating partition plate, which also serves as a support for the lamellar evaporator 19.
Wie insbesondere aus Figur 3 hervorgeht, weist die Trennplatte 22 ein schalenähnlich ausgebildetes, einstückig aus Kunststoff-Spritzguß gebildetes Tragteil 23 mit einem Schalenraum umschließenden Schalenwänden 24 auf. Das Tragteil 23 an seiner in Einbaulage von der Tür 14 abgewandten Rückseite mit einem rinnenartigen Fortsatz 25 ausgestattet (siehe hierzu Fig. 1 und Fig. 2), welcher in etwa mittig zur Breite des Tragteiles 23 angeordnet ist und welcher an seinem freien Ende einen die Breite des Rinnenbettes überspannenden Bügel 26 aufweist. Auf die Schalenwände 24 des Tragteiles 23 ist in Art eines Deckels eine einstückig durch Tiefziehen einer Aluminiumblechplatine hergestellte, als Tauwasserauffangschale ausgebildete Abdeckung 27 aufsetzbar, welche in Art einer flachen Schale ausgeführt und mit Schalenwänden 28 ausgestattet ist, an deren freien Enden eine vom Schalenraum weggerichtete Abwinklung 29 vorgesehen ist, mit deren Hilfe sich die Abdeckung 27 an den freien Rändern der Schalenwände 24 abstützt. Die Schalenwände 28 sind im wesentlichen rechtwinklig zu einem Schalenboden 30 angeordnet, welcher durch die Abstützung der Abdeckung 27 an den Schalenwänden 24 in den Schalenraum des Tragteiles 23 eintaucht. Der Schalenboden 30 ist im wesentlichen in zwei Bereiche I und II unterteilt, wobei ein erster Bereich I dem Lamellenverdampfer 19 zugeordnet ist. Dieser ist mit zur Befestigung des Lamellenverdampfers dienenden Verstärkungsteilen 31 versehen, welche als Hinterlegteile ausgebildet sind und auf der im Schaienraum des Tragteiles 23 zugewandten Unterseite des Schalenbodens 30 festgesetzt sind. An dem Bereich I des Schalenbodens 30 ist ein zweiter Bereich II einstückig angeformt, welcher gegenüber dem Bereich I geneigt ist und welcher in seinem freien vom Bereich I abgewandten Ende mit einer Tauwasserablaufrinne 32 versehen ist, auf weiche hin das Gefälle des Bereiches II ausgerichtet ist. Die Tauwasserablaufrinne 32 ist wie insbesondere aus Figur 2 hervorgeht, in etwa mittig zu der als Tauwasserauffangschale dienenden Abdeckung 27 angeordnet und taucht bei auf das Tragteil 23 aufgesetzter Abdeckung 27 in das Rinnenbett des rinnenartigen Fortsatzes 25 ein, wobei das freie Ende der Tauwasserablaufrinne 32 durch den Bügel 26 geführt zugleich fixiert ist.As can be seen in particular from FIG. 3, the separating plate 22 has a shell-like support part 23 which is formed in one piece from plastic injection molding and has shell walls 24 surrounding a shell space. The support member 23 is equipped on its rear side facing away from the door 14 with a groove-like extension 25 (see FIGS. 1 and 2), which is arranged approximately in the center of the width of the support member 23 and which at its free end one Has width of the channel bed spanning bracket 26. On the shell walls 24 of the support member 23, a cover 27 made in one piece by deep-drawing an aluminum sheet plate and designed as a condensate collecting tray can be placed, which is designed in the manner of a flat shell and is equipped with shell walls 28, at the free ends of which an angled away from the shell space 29 is provided, with the aid of which the cover 27 is supported on the free edges of the shell walls 24. The shell walls 28 are arranged essentially at right angles to a shell base 30, which is immersed in the shell space of the supporting part 23 by the support of the cover 27 on the shell walls 24. The tray bottom 30 is essentially divided into two areas I and II, a first area I being assigned to the lamella evaporator 19. This is provided with reinforcing parts 31 serving to fasten the lamella evaporator, which are designed as backing parts and are fixed on the underside of the shell bottom 30 facing in the rail space of the support part 23. A second area II is integrally formed on the area I of the shell bottom 30, which is inclined with respect to the area I and which is provided in its free end facing away from the area I with a condensate drainage channel 32, towards which the slope of the area II is oriented. The defrost water drainage channel 32, as can be seen in particular from FIG. 2, is arranged approximately in the middle of the cover 27 serving as the defrosting water collecting tray and, when the cover 27 is placed on the supporting part 23, plunges into the channel bed of the channel-like extension 25, the free end of the defrosting water drainage channel 32 being passed through Bracket 26 is guided at the same time fixed.
Wie insbesondere aus den Figuren 2 und 3 hervorgeht, ist die Abdeckung 27 in ihrem die Tauwasserablaufrinne 32 aufweisenden Bereich II, an dessen dem Schalenraum des Tragteils 23 zugewandten Unterseite, in einem zwischen dem auslaufseitigen Ende der Tauwasserablaufrinne 32 und dem Übergang zum Bereich I liegenden Zwischenabschnitt mit einer Halteschale 33 versehen, welche zusammen mit ihrem Schalenboden 34 und mit ihren Schalenwänden 35 einen Aufnahmeraum 36 hermetisch umschließt, wobei zur Erzeugung des hermetisch umschlossenen Aufnahmeraums 36 die Schalenwände 35 mit ihren freien Rändern an der Unterseite des Bereiches II zumindest flüssigkeitsdicht festgesetzt sind. Wie besonders aus Figur 2 ersichtlich ist, nimmt der Aufnahmeraum 36 im wesentlichen die gesamte Breite der Trennplatte 22 ein und dient zu einer VDE-Richtlinien gerecht werdenden Unterbringung eines in schleifenähnlicher Form verlegten Rohrheizkörpers 37, welcher zur ausreichenden Beheizung der Tauwasserablaufrinne 32 mit zwei seiner Schleifen in deren Rinnenbett geführt ist und welcher zumindest annähernd über die Breite des Aufnahmeraumes 36 zur ausreichenden Beheizung des Bereiches II der Abdeckung 27 angeordnet ist. Die Abdeckung 27 umschließt durch ihre deckelartige Anordnung auf dem Tragteil 23 zusammen mit diesem einen Zwischenraum 38, welcher mit in flüssigen Ausgangskomponenten eingebrachten und durch Aufschäumen erzeugten Wärmeisolationsmaterial 39 verfüllt ist, durch dessen adhäsive Wirkung das Tragteil 33 und die Abdeckung 27 zu einer zumindest weitestgehend formsteifen, die Trennplatte 22 bildenden Einheit verbunden ist.As can be seen in particular from FIGS. 2 and 3, the cover 27 is in its area II, which has the condensation water drainage channel 32, on its underside facing the shell space of the supporting part 23, in an intermediate section lying between the outlet-side end of the condensation water drainage channel 32 and the transition to area I. provided with a holding shell 33 which, together with its shell bottom 34 and with its shell walls 35, hermetically encloses a receiving space 36, the shell walls 35 being at least liquid-tightly fixed with their free edges on the underside of the area II in order to produce the hermetically enclosed receiving space 36. As can be seen particularly from FIG. 2, the receiving space 36 essentially occupies the entire width of the separating plate 22 and serves to accommodate a tubular heater 37 laid in a loop-like form, which is in accordance with VDE guidelines and which is used to adequately heat the condensate drainage channel 32 with two of its loops is guided in the channel bed and which is arranged at least approximately over the width of the receiving space 36 for sufficient heating of the area II of the cover 27. Due to its cover-like arrangement on the support part 23, the cover 27 encloses together with this an intermediate space 38, which is filled with thermal insulation material 39 introduced into liquid starting components and produced by foaming, through the adhesive effect of which the support part 33 and the cover 27 are at least largely rigid , the partition plate 22 forming unit is connected.
Wie aus Figur 1 ersichtlich ist, ist die Trennplatte 22 im Einbauzustand im Gefrierschrank 10 derart angeordnet, daß sowohl die Tauwasserablauf rinne 32 als auch der rinnenartige Fortsatz 25 in den durchflossenen Querschnitt des Rohrstutzes 12 eintaucht und bezüglich dessen durchströmbaren Querschnitt mit einem als Formteil ausgebildeten Dichtmittel 40 abgedichtet sind. Im Einbauzustand der Trennplatte 32 ist diese mit ihrer Tauwasserauffangschale 27 zum Rohrstutzen 12, zur Ausbildung eines dahin gerichteten Gefälles, geneigt und dient als Träger des Lamellenverdampfers 19, welcher mit die Verstärkungsteile 31 durchdringenden Befestigungsmittel 41 an der Trennplatte 22 festgesetzt ist. Im festgesetzten Zustand steht die Widerstandsheizung 20 in wärmeleitendem Kontakt mit dem Bereich I der Abdeckung 27, wodurch diese zumindest im Bereich I, des dafür in Anwendung gebrachten gut wärmeleitenden Materials auf der Basis metallischer Werkstoffe, wie beispielsweise Aluminium, gleichmäßig erwärmt wird. Für eine ebenso gleichmäßige Erwärmung des Bereiches II der Abdeckung 27 sorgt der Rohrheizkörper 37, welcher insbesondere die Tauwasserablaufrinne 32 der einstückig geformten Abdeckung 27 derart beheizt, daß eine Vereisung der Tauwasserablaufrinne 32 nach erfolgtem Abtauen des Lamellenverdampfers 19 stets sicher verhindert ist. Unterstützend zur Verhinderung der Eisbildung wirkt sich die hindernisfreie Oberfläche der Tauwasserablaufrinne 32 und des gesamten Bereiches II der Abdeckung 27 aus, dessen hindernisfreie Oberfläche durch die Anordnung des Rohrheizkörpers 27 innerhalb des Aufnahmeraumes 36, also außerhalb der vom Schmelzwasser des abtauenden Verdampfers überstrichenen Zone, bewirkt ist. As can be seen from Figure 1, the partition plate 22 is arranged in the installed state in the freezer 10 such that both the condensate drain 32 and the channel-like extension 25 in the flow cross section of the Immersed pipe socket 12 and are sealed with respect to its flowable cross section with a sealant 40 formed as a molded part. In the installed state of the separating plate 32, this is inclined with its condensate collecting tray 27 to the pipe socket 12, to form a slope directed towards it, and serves as a support for the finned evaporator 19, which is fixed to the separating plate 22 with fastening means 41 penetrating the reinforcing parts 31. In the fixed state, the resistance heater 20 is in heat-conducting contact with the area I of the cover 27, as a result of which it is heated uniformly at least in area I, of the heat-conducting material based on metallic materials, such as aluminum, which is used for this purpose. An equally uniform heating of area II of the cover 27 is provided by the tubular heater 37, which in particular heats the condensate drain 32 of the integrally formed cover 27 such that icing of the condensate drain 32 is always reliably prevented after the lamella evaporator 19 has been defrosted. To prevent ice formation, the obstacle-free surface of the condensate drain 32 and the entire area II of the cover 27 has an effect, the obstacle-free surface of which is caused by the arrangement of the tubular heating element 27 within the receiving space 36, i.e. outside the zone covered by the melt water of the defrosting evaporator .
