Description

Die Erfindung betrifft ein Gefriergerät mit einem wärmeisolierenden Gehäuse, innerhalb welchem wenigstens ein Gefrierraum angeordnet ist, der von einem Verdampfer gekühlt ist, welcher bei Bedarf abtaubar ist, wobei das beim Abtauen anfallende Schmelzwasser sich an der gefrierraumseitigen Oberfläche des Gefrierraumbodens sammelt und dort einem die Wärmeisolation des Bodens durchringenden Ablaufrohr zugeführt ist, dessen freies auslaufseitiges Ende mit einer Ablaufleitung verbunden ist.The invention relates to a freezer with a heat insulating Housing within which at least one freezer compartment is arranged, which is cooled by an evaporator, which is defrostable when needed, the one that occurs during defrosting Melt water on the surface of the freezer compartment of the freezer compartment floor and there the heat insulation of the floor penetrating drain pipe is, the free outlet end with a drain line connected is.

Aus dem DE-GM 77 03 184 ist ein Gefrierschrank bekannt, dessen wärmeisolierter Gefrierraumboden mit einem die Bodenstärke durchdringenden Ablaufrohr ausgestattet ist. Dies ist an seinem auslaufseitigen Ende an eine als Ablaufwinkel ausgebildete Ablaufleitung angeschlossen, welche zum Zwecke ihres Anschlusses mit einem Rohrabschnitt in den durchströmbaren Querschnitt des Ablaufrohres ragt und welche am Mantel des Rohrabschnitts mit daran angeformten Dichtlippen versehen ist, welche mit der Innenwandung des Ablaufrohres zusammenwirken, um eine Abdichtung zwischen den beiden zusammengefügten Leitungsabschnitten zu erzeugen. Als weitere, die Dichtheit zwischen den zusammengefügten Leitungsabschnitten unterstützende Maßnahme sind am stirnseitigen Ende des ablaufseitigen Abschnitts des Ablaufrohres angeordnete Innenlippen vorgesehen, welche auf den Rohrmantel des dem Ablaufrohr zugewandten Rohrabschnitts einwirken.A freezer is known from DE-GM 77 03 184, the thermally insulated freezer floor with a floor thickness penetrating drain pipe is equipped. This is at its outlet end to a drainage bracket Drain line connected, which for the purpose of their Connection with a pipe section in the flowable Cross section of the drain pipe protrudes and which on the jacket the pipe section with sealing lips molded onto it which cooperate with the inner wall of the drain pipe, to create a seal between the two To generate line sections. As another that Tightness between the joined pipe sections Supportive measures are at the front end of the drain side Section of the drain pipe arranged inner lips provided which on the pipe jacket of the drain pipe act on the facing pipe section.

Bei einem derartigen Anschluß zwischen Ablaufrohr und Ablaufleitung könnte das Ablaufrohr hinsichtlich seiner Länge im wesentlichen auf die Stärke des Gefrierschrankbodens angepaßt sein, wodurch sich die Höhe des zur Aufnahme der Ablaufleitung dienenden, unterhalb des Gefrierschrank-Innenraums angeordneten Raumes verringern ließe, doch birgt eine solche Ausbildung der Verbindungsstelle zwischen beiden Leitungsabschnitten die Gefahr, daß an der Verbindungsstelle Leckwasser austreten kann, insb. dann, wenn entweder die Dichtlippen am Rohrmantel der Ablaufleitung oder die Innenlippen am Ablaufrohr eine nicnt ohne weiteres erkennbare Fehlstelle aufweisen oder die Montage der beiden Leitungsabschnitte zueinander nicht mit der nötigen Sorgfalt ausgeführt wurde. Eine sorgfältige, die Dichtheit an der Anschlußstelle gewährleistende Montage bedeutet aber wiederum eine nicht unwesentliche Erhöhung der Montagezeit.With such a connection between the drain pipe and drain pipe could the drain pipe in terms of its length essentially adapted to the thickness of the freezer base be, which increases the height of the drain pipe serving, below the freezer interior arranged space could be reduced, but hides one such formation of the junction between the two line sections the danger that at the junction Leakage water can leak, especially if either the Sealing lips on the pipe casing of the drain pipe or the inner lips not easily recognizable on the drain pipe Have a defect or the assembly of the two line sections not executed each other with the necessary care has been. Careful, the tightness at the connection point ensuring assembly means again a not insignificant increase in assembly time.

Ein weiteres Kühlgerät mit einem Tauwasserablauf ist aus dem DE-GM 84 36 339 bekannt, welcher im wesentlichen aus einer rinnenförmigen Ablaufleitung, einer zur Führung der Ablaufleitung dienenden, mit einem Rohrstück ausgestatteten Gegenführung und einem im wesentlichen rohrartigen Ablaufstutzen gebildet ist. Dieser ist am Rohrmantel seines auslaufseitigen Endes mit mehreren, im Abstand übereinander angeordneten und gegenüber der Wärmeisolierung des Kühlraumbodens vorstehenden Halterippen ausgestattet, auf welche der an der Gegenführung angeordnete Rohrstutzen zum Anschluß der Ablaufleitung an den Ablaufstutzen um einen durchgehenden Tauwasserablauf zu erzeugen, aufschiebbar ist.Another cooling device with a condensate drain is from the DE-GM 84 36 339 known, which consists essentially of a channel-shaped drain line, one for guiding the drain line serving, equipped with a pipe section counter-guidance and an essentially tubular drain connector is formed. This is on the pipe jacket of its outlet side End with several, one above the other and protruding from the thermal insulation of the cold room floor Holding ribs fitted, on which the on the opposite guide arranged pipe socket for connecting the drain pipe to the drain pipe around a continuous condensate drain to generate is postponed.

Infolge des zu Anschlußzwecken in das Rohrstück der Gegenführung ragende auslaufseitige Ende des Ablaufstutzens kann auf Dichtungsmaßnahmen zwischen beiden verzichtet werden, sodaß die Halterippen lediglich zu Befestigungszwecken dienen können und sich dadurch die Montage der Gegenführung an den Ablaufstutzen deutlich vereinfacht. Jedoch bedingt eine derartig aufgebaute Anschlußkonstruktion zwischen dem Ablaufstutzen und der Gegenführung, daß ersterer deutlich über die Unterseite des Gefrierraumbodens übersteht um ein Aufschieben des Rohrstückes zu ermöglichen. Hieraus resultiert eine nicht unwesentliche Erhöhung des Montageraumes unterhalb des Kühlraumbodens des Kühlgerätes.As a result of the connection in the pipe section of the opposite guide protruding outlet end of the drain socket can sealing measures between the two are dispensed with, so that the retaining ribs are used only for fastening purposes can and thereby the assembly of the counter guide the drain socket significantly simplified. However, one requires such constructed connecting structure between the drain pipe and the countermeasure that the former is clearly above the bottom of the freezer floor protrudes by being pushed open to enable the pipe section. This results in a not insignificant increase in the assembly space below the refrigerator compartment floor.

Durch die erfindungsgemäße Lösung ist eine Wasserführung für einen Tauwasserablauf erzeugt, bei welchem über die gesamte Länge ohne zusätzliche, meist aufwendige und die Montagefreundlichkeit deutlich herabsetzende Abdichtungsmaßnahmen Leckverluste stets sicher vermieden sind. Gleichzeitig ermöglicht die erfindungsgemäße Lösung eine Minimierung der Gesamtbauhöhe des Tauwasserablaufes zugunsten einer Gefrierraumvergrößerung, da aufgrund der erfindungsgemäßen Verbindungsart ein deutlich über die Bodenstärke vorstehender Anschlußabschnitt des Ablaufrohres sich erübrigt.The solution according to the invention provides a water supply for creates a condensate drain in which over the entire Length without additional, usually complex and easy to install significantly reducing sealing measures Leakage losses are always safely avoided. Allows at the same time the solution according to the invention minimizing the Overall height of the condensate drain in favor of enlarging the freezer compartment, because due to the type of connection according to the invention a connection section protruding clearly above the floor thickness the drain pipe is unnecessary.

Die Nutenbreite der Führungsnut 21 ist auf die Wandstärke einer zu einer rinnenförmig ausgebildeten Ablaufleitung 22 gehörenden Rinnenwandung 23 abgestimmt, deren wassereinlaufseitiges Ende in Art eines Kreishohlzylinders 24 ausgebildet ist, dessen Wandungshöhe gegenüber den zum einlaufseitigen Ende hin verlaufenden, die Breite der rinnenförmigen Ablaufleitung begrenzenden, seitlichen Rinnenwandungen erhöht ausgeführt ist. Ferner ist der Kreishohlzylinder 24 an seinen dem auslaufseitigen Ende der Ablaufleitung 22 zugewandten Abschnitt mit einer Auslauföffnung 25 versehen.The drain pipe 17 connected to the end profile 16 has on its outlet side opposite the freezer compartment 13 End, within its essentially circular trained, flowable cross section 18 projections 19, which over the entire circumference of the flow Cross section 18 are arranged, protrude into this and thus reduce its diameter. Concentric around is the flow-through cross section 18 of the drain pipe 17 a cross-section at the end of its outlet end annular drip nose 20 arranged, the Diameter is larger than that of the cross-section through which flow can pass 18. At a distance from the drip nose 20 is one in the end profile 16 molded, also concentric arranged around the drain pipe 17 and into the thermal insulation of the freezer compartment floor 15 protruding, but opposite the thermal insulation through the walls of the end profile 16 delimited circular guide groove 21 is provided. This is on their from the thermal insulation of the freezer floor 15 facing end face open and in cross section rectangular. The groove width of the Guide groove 21 is groove-shaped to a wall thickness trained drain line 22 belonging channel wall 23 matched, the water inlet end in Kind of a circular hollow cylinder 24 is formed, the Wall height opposite that towards the inlet end extending, the width of the gutter-shaped drain pipe delimiting, lateral channel walls are raised is. Furthermore, the circular hollow cylinder 24 is on its outlet side End of the drain line 22 facing section provided with an outlet opening 25.

Innerhalb des Kreishohlzylinders 24 ist zentrisch um dessen Mittelpunkt ein weiterer Kreishohlzylinder angeordnet, welcher in zwei gleiche Bogenlänge aufweisende zueinander freigesparte Wandungssegmente unterteilt ist, von denen jedes als Rasthaken 26 ausgebildet und mit einem seiner stirnseitigen Enden mit dem Rinnenboden der rinnenförmigen Ablaufleitung 22 verbunden ist. Die Wandungssegmente weisen mantelseitig an ihrem freien, vom Rinnenboden abgewandten Ende zum Zweck ihrer Ausbildung als Rasthaken 26 Einführungsschrägen 27 auf, denen zum Rinnenboden hin Rastnasen 28 nachgeschaltet sind. Unmittelbar unterhalb der Rastnasen 28 sind die als Rasthaken 26 dienenden Wandungssegmente des Kreishohlzylinders an ihrer Mantelseite mit einer Aufnahmenut 29 ausgestattet, welche über den Umfang des Kreishohlzylinders verläuft und welche hinsichtlich ihrer Nutentiefe auf die Breite der Vorsprünge 19 abgestimmt ist, jedoch hinsichtlich ihrer Nutenbreite größer als die Höhe der Vorsprünge 19 bemessen ist. Within the circular hollow cylinder 24 is centered around it Another circular hollow cylinder arranged in the center, which in two equal arc length to each other free wall segments is divided, each of which formed as a locking hook 26 and with one of his front ends with the channel bottom of the channel-shaped Drain line 22 is connected. The wall segments point on the outside of the jacket facing away from the channel bottom End for the purpose of their training as locking hooks 26 chamfers 27 on, which catches to the channel bottom 28 are connected downstream. Immediately below the locking lugs 28 are the wall segments serving as locking hooks 26 Circular hollow cylinder on its jacket side with a receiving groove 29 equipped, which over the circumference of the circular hollow cylinder runs and which in terms of their groove depth is matched to the width of the projections 19, however in terms of their groove width larger than the height of the projections 19 is dimensioned.

Ferner sind die als Rasthaken 26 ausgebildeten, aus einem Kreishohlzylinder freigesparten Wandungssegmente im Anschluß an die Aufnahmenut 29 mit drei in etwa gleichmäßigen Winkelabständen über den Mantel des Kreishohlzylinders verteilt angeordneten Durchtrittsöffnungen 30 für das Schmelzwasser versehen, deren dem Rinnenboden der Ablaufleitung 22 zugewandte Seite in einer Ebene mit diesem liegt, wobei die dem auslaufseitigen Ende der Ablaufleitung 22 zugewandte Durchtrittsöffnung 27 im wesentlichen zur Auslauföffnung 25 ausgerichtet ist.Furthermore, the designed as locking hooks 26, from one Circular hollow cylinder free wall segments in the connection to the receiving groove 29 with three approximately uniform Angular distances distributed over the jacket of the circular hollow cylinder arranged through openings 30 for the melt water provided whose the bottom of the drain line 22nd facing side lies in one plane with this, the facing the outlet end of the drain line 22 Passage opening 27 essentially to the outlet opening 25 is aligned.

Wie sowohl Fig. 2 als auch Fig. 3 zeigt, ist die Ablaufleitung 22 mit dem Abflußrohr 17 verbindbar. Zur Herstellung der Verbindung werden die durch Zylinderwandung des Kreishohlzylinders gebildeten Rasthaken 26 in den durchströmbaren Querschnitt 18 des Abflußrohres 17 eingeführt. Durch die in Einführrichtung voraneilende Einführschräge 27 werden die zwei als Rasthaken 26 ausgebildeten Segmente des Kreishohlzylinders aufgrund der zwischen ihnen erzeugten Freisparungen elastisch ferdernd aufeinander zu bewegt. Nach Erreichen der Rastposition, in welcher die Rastnase 28 die Vorsprünge 19 auf deren dem einlaufseitigen Ende des Abflußrohres 17 zugewandten Oberfläche hintergreifen, federn die Rasthaken 26 in ihre Ausgangslage zurück. Durch die Verrastung ist zwischen den Vorsprüngen 19 und der Aufnahmenut 29, welche beide in Art einer Führung zusammenwirken, ist ein Drehgelenk erzeugt, aufgrund welchem es möglich ist, die Ablaufleitung 22 um das Zentrum des Abflußrohres 17 zu verschwenken. Dabei ist das erzeugte Drehgelenk durch das geführte Eingreifen des freien Endes des Kreishohlzylinders 24 in die Führungsnut 21, der zusätzlich gegen das Drehgelenk belastende Drehmomente unterstützt. As both Fig. 2 and Fig. 3 shows, the drain line 22 connectable to the drain pipe 17. For the production the connection through the cylinder wall of the circular hollow cylinder formed latching hooks 26 in the flowable Cross section 18 of the drain pipe 17 introduced. By the leading bevel 27 leading in the direction of insertion the two segments of the snap hook formed as Circular hollow cylinder due to the generated between them Eliminations resiliently moving towards each other. After reaching the locking position in which the locking lug 28 the projections 19 on the inlet end of the Reach behind the drain pipe 17 facing surface, spring the latching hooks 26 return to their starting position. By the catch is between the projections 19 and the receiving groove 29, which both work together in the manner of a tour, is created a swivel, on the basis of which it is possible is, the drain line 22 around the center of the drain pipe 17 to pivot. Here is the swivel created through the guided intervention of the free end of the Circular hollow cylinder 24 in the guide groove 21, the additional supports torques loading against the swivel.

Zum Verschwenken der Ablaufleitung 22 ist an deren auslaufseitigem Ende eine Handhabe 31 vorgesehen, mit Hilfe derer die Ablaufleitung 22 von der in Fig. 2 gezeigten zurückgeschwenkten Ruhestellung in seine in Fig. 3 dargestellte Betriebsstellung verschwenkbar ist.To pivot the drain line 22 is on the outlet side End provided a handle 31, with the help of which the drain line 22 is pivoted back from that shown in FIG Rest position in its operating position shown in Fig. 3 is pivotable.

Zum Abführen des während eines Abtauvorganges entstehenden Schmelzwassers befindet sich die Ablaufleitung 22 in ihrer Betriebsstellung, wobei das Schmutzwasser aufgrund des gefrierraumseitig in den Gefrierraumboden 15 eingearbeiteten Gefälles dem Abflußrohr 17 zugeführt. Von dort wird es in den als Rasthaken 26 ausgebildeten Kreishohlzylinder geleitet und fließt über in dessen Wandung eingearbeitete Durchtrittsöffnungen 30 zur Auslauföffnung 25 im Kreishohlzylinder 24, von es dem auslaufseitigen Ende der Ablaufleitung 22 zugeführt ist. Das gegebenenfalls über die Rastverbindung zwischen den als Rasthaken 26 dienenden Segmenten des Kreishohlzylinders und den Vorsprüngen 19 abfließende Schmelzwasser wird anhand der dem Abflußrohr 17 in Fließrichtung des Schmelzwassers nachgeschalteten Abtropfnase 20, welche im gehalterten Zustand der Ablaufleitung 22 innerhalb der Wandungen des Kreishohlzylinders 24 angeordnet ist, dem Rinnenlauf der Ablaufleitung 22 sicher zugeführt.To remove the resulting during a defrosting process Melt water is the drain line 22 in it Operating position, the dirty water due to the freezer compartment side worked into the freezer compartment floor 15 Slope fed to the drain pipe 17. From there it gets in the circular hollow cylinder designed as a locking hook 26 passed and flows through passage openings worked into its wall 30 to the outlet opening 25 in the circular hollow cylinder 24, from it the outlet end of the drain pipe 22 is supplied. If necessary, via the locking connection between the segments of the serving as locking hook 26 Circular hollow cylinder and the projections 19 flowing away Melt water is based on the drain pipe 17 in the direction of flow of the melt water downstream drip nose 20, which in the held state of the drain line 22 inside arranged the walls of the circular hollow cylinder 24 is safely fed to the gutter of the drain line 22.
