Description

Die vorliegende Erfindung betrifft eine Kühl- und/oder eine Gefriertruhe, die über eine Rinne zum Ablaufen von Tauwasser verfügt.The present invention relates to a refrigerator and/or freezer which has a channel for draining condensate.

Die Rinne im Inneren der Kühl- und/oder Gefriertruhe ist so ausgestaltet, dass sie sich an einer Seitenwand der Kühl- und/oder Gefriertruhe ansetzendes Tauwasser beim herunterfließen aufnimmt und aus der Kühl- und/oder Gefriertruhe führt. Eine solche Rinne ist auch von Vorteil, wenn die Kühl- und/oder Gefriertruhe über eine automatische bzw. semiautomatische Abtaufunktion verfügt, bei der die Verdampferflächen durch ein gezieltes Beheizen dieser von einem Eisaufbau befreit werden. Das hierbei im Inneren entlang einer Seitenwand der Kühl- und/oder Gefriertruhe herunterfließende Wasser wird dann mittels der Rinne aufgenommen und nach außen geführt, wo es verdampfen kann.The channel inside the refrigerator and/or freezer is designed in such a way that it collects condensate that forms on a side wall of the refrigerator and/or freezer as it flows down and leads it out of the refrigerator and/or freezer. Such a channel is also advantageous if the refrigerator and/or freezer has an automatic or semi-automatic defrost function, in which the evaporator surfaces are freed of ice build-up by heating them in a targeted manner. The water that flows down the inside along a side wall of the refrigerator and/or freezer is then collected by the channel and led to the outside, where it can evaporate.

Mithilfe der semiautomatischen oder automatischen Abtauung wird verhindert, dass sich Eiskristalle an der Innenwand einer Kühl- und/oder Gefriertruhe im Bereich der Verdampferfläche ansetzen, die die Wirksamkeit des Kühlkreislaufs einschränken und das für Waren zur Verfügung stehende Volumen der Kühl- und/oder Gefriertruhe vermindern.Semi-automatic or automatic defrosting prevents ice crystals from settling on the inner wall of a refrigerator and/or freezer in the area of the evaporator surface, which would limit the effectiveness of the cooling circuit and reduce the volume of the refrigerator and/or freezer available for goods.

Es ist daher Stand der Technik im Innenraum des Korpus einer Kühl- und/oder Gefriertruhe eine Rinne vorzusehen, die typischerweise auf einer kleinen Stufe der Seitenwand angeordnet ist. Die beiden Abschnitte der Seitenwand, die durch eine solche Rinne getrennt sind, verlaufen demnach in unterschiedlichen Ebenen.It is therefore state of the art to provide a channel in the interior of the body of a refrigerator and/or freezer, which is typically arranged on a small step of the side wall. The two sections of the side wall that are separated by such a channel therefore run on different levels.

Ein solches aufbauendes Rinnensystem ist jedoch anfällig für Verschmutzung und verringert den für Waren zur Verfügung stehenden Innenraum der Kühl- und/ oder Gefriertruhe.However, such a gutter system is susceptible to contamination and reduces the interior space available for goods in the refrigerator and/or freezer.

Dabei ist zu beachten, dass das Aufnahmevolumen einer Kühl- und/oder Gefriertruhe eines der Hauptkriterien von Kunden, insbesondere von Gewerbekunden ist und oftmals ein entscheidendes Kriterium beim Kauf eines solchen Geräts darstellt. In Bezug auf das beträchtliche Verschmutzungsrisiko der Tauwasserrinne bei einem aufbauenden (stufenförmigen) Rinnensystem besteht auch die Gefahr einer technischen Störung, wenn der Verschmutzungsgrad so groß ist, dass ein Ablaufen des Tauwassers aus dem Gerät hinaus nicht mehr möglich ist. Dabei kann vorkommen, dass Tauwasser aus der Rinne hinaus in den Korpus hinein läuft und Waren beschädigt. Von daher ist es erforderlich, in zyklischen Abständen die Tauwasserrinne zu reinigen, damit ein Beschädigen der Waren durch aus der Tauwasserrinne austretendes Wasser nicht erfolgt. Von daher ist ein solches Gerät nach dem Stand der Technik serviceintensiv und anfällig für Verunreinigungen. Insbesondere bei der gewerblichen Nutzung von Kühl- und/oder Gefriertruhen halten Verunreinigungen Kunden davon ab, Waren zu kaufen, von daher ist es hier von höchster Wichtigkeit, Verunreinigungen schnellstmöglich Ein Kühlmöbel nach dem Oberbegriff des Anspruchs 1 ist aus DE 298 05 421 U1 bekannt.It should be noted that the capacity of a refrigerator and/or freezer is one of the main criteria for customers, especially commercial customers, and is often a decisive criterion when purchasing such an appliance. In relation to the considerable risk of contamination of the condensate channel in a stepped channel system, there is also the risk of a technical fault if the degree of contamination is so great that it is no longer possible for the condensate to drain out of the appliance. This can cause condensate to run out of the channel into the body and damage goods. It is therefore necessary to clean the condensate channel at regular intervals to prevent damage to goods caused by water escaping from the condensate channel. This type of appliance is therefore service-intensive and susceptible to contamination based on the state of the art. Particularly in the commercial use of refrigerators and/or freezers, contamination prevents customers from buying goods, so it is of the utmost importance to remove contamination as quickly as possible. A refrigeration unit according to the preamble of claim 1 is made of DE 298 05 421 U1 known.

Die vorstehend aufgeführten Nachteile werden mit einer der Kühl- und/oder Gefriertruhe gemäß der Merkmale des Anspruch 1 gelöst.The disadvantages listed above are solved with a refrigerator and/or freezer according to the features of claim 1.

Eine erfindungsgemäße Kühl- und/oder Gefriertruhe, umfasst dabei einen Korpus zur Aufnahme von einem zu temperierenden Kühlgut, und eine Rinne zum Ansammeln und Abführen von Tauwasser, wobei die Rinne entlang einer Seitenwand des Korpus der Kühl- und/ oder Gefriertruhe verläuft. Ferner zeichnet sich die Kühl- und/oder Gefriertruhe dadurch aus, dass die Rinne eine Vertiefung gegenüber der durch die Seitenwand definierten Ebene aufweist.A refrigerator and/or freezer according to the invention comprises a body for receiving goods to be cooled and a channel for collecting and draining condensate, the channel running along a side wall of the body of the refrigerator and/or freezer. The refrigerator and/or freezer is further characterized in that the channel has a recess opposite the plane defined by the side wall.

Indem die Rinne in einer vertieften Anordnung gegenüber der Seitenwand angeordnet ist und nicht mehr auf die Seitenwand entsprechend einer Stufe oder in einer anderen Ausformung aufgesetzt ist, vergrößert sich die Innenabmessung in dem Bereich der mit der Vertiefung versehenen Rinne. Dies führt zu einem Zugewinn an Volumen, sodass es möglich ist, mehr Waren bei gleichen Außenabmessungen einer Kühl- und/oder Gefriertruhe aufzunehmen. Die Rinne umfasst eine Vertiefung in der Seitenwand.By arranging the channel in a recessed arrangement opposite the side wall and no longer being placed on the side wall in a step or other shape, the internal dimensions in the area of the channel provided with the recess are increased. This leads to an increase in volume, so that it is possible to accommodate more goods with the same external dimensions of a refrigerator and/or freezer. The channel comprises a recess in the side wall.

Nach einer bevorzugten Ausführungsform der Erfindung ist die Rinne eine nutartige Ausnehmung in der Seitenwand.According to a preferred embodiment of the invention, the channel is a groove-like recess in the side wall.

Auch wird durch die Vertiefung der Rinne gegenüber der durch die Seitenwand definierte Ebene die Anfälligkeit für Verschmutzungen der Rinne vermindert, da die für eine Verunreinigung der Rinne ursächlichen Partikel dem Gesetz der Gravitation unterliegen und lotrecht nach unten fallen. Bei der erfindungsgemäßen vertieften Rinne fällt - im Gegensatz zu einer aufbauenden Rinne nach dem Stand der Technik - nur ein verringerter Anteil oder gar keine Partikel in die Rinne, sodass die Gefahr einer Verunreinigung der Tauwasserrinne vermindert wird.The recessed channel in relation to the plane defined by the side wall also reduces the susceptibility of the channel to contamination, as the particles causing the channel to become dirty are subject to the law of gravity and fall vertically downwards. In the case of the recessed channel according to the invention - in contrast to a built-up channel according to the state of the art - only a reduced proportion or no particles at all enter the gutter, thus reducing the risk of contamination of the condensate gutter.

Die Flächenabschnitte der Seitenwand, die an der zur Rinne gehörenden Vertiefung angrenzen, sind zueinander bündig. Durch die bündige Ausrichtung der an die Vertiefung der Rinne angrenzenden Flächenabschnitte der Seitenwand fallen Partikel, die für eine Verunreinigung der Rinne sorgen können, nicht mehr in die Rinne hinein sondern an dieser vorbei.The surface sections of the side wall that border the recess belonging to the gutter are flush with each other. Due to the flush alignment of the surface sections of the side wall that border the recess of the gutter, particles that could cause contamination of the gutter no longer fall into the gutter but instead pass by it.

Weiter ist eine solche bündige Ausrichtung der Flächenabschnitte, die durch die Rinne getrennt werden, auch für das Aufnehmen von in die Kühl- und/oder Gefriertruhe zu lagernden Waren von Vorteil, da die Rinne nun nicht mehr zwei in ihrer Tiefenrichtung voneinander beabstandete Flächen unterteilt, die ein gleichmäßiges Anlegen von Waren an die Seitenwand über die gesamte Höhe nicht ermöglicht.Furthermore, such a flush alignment of the surface sections separated by the channel is also advantageous for receiving goods to be stored in the refrigerator and/or freezer, since the channel no longer divides two surfaces spaced apart from each other in their depth direction, which does not allow goods to be placed evenly on the side wall over the entire height.

Nach der Erfindung weist die Vertiefung in der Seitenwand eine Geometrie auf, die bei einer vertikalen Ausrichtung der Seitenwand ein von oben in Richtung Vertiefung fließendes Wasser in die Rinne führt.According to the invention, the recess in the side wall has a geometry which, when the side wall is aligned vertically, leads water flowing from above towards the recess into the channel.

Um das von oben herabfließende Tauwasser in die vertiefte Rinne zu leiten, ist es erforderlich, die Geometrie der Vertiefung so zu wählen, damit die Oberflächenspannung ausreicht, um das Wasser auch überhängend in die Rinne zu führen und ein vorheriges Abtropfen vermieden wird. Nach der Erfindung steht der Rinnenbauch, der den Abschnitt der Rinne bezeichnet, der bei einer vertikalen Ausrichtung der Seitenwand mit Wasser füllbar ist, mit einem die Vertiefung der Seitenwand umfassenden Zuführabschnitt in Verbindung, wobei die Oberflächenspannung des Wassers ausreichend ist, um Wasser überhängend in den Rinnenbauch zu führen.In order to direct the condensate flowing down from above into the recessed gutter, it is necessary to select the geometry of the recess so that the surface tension is sufficient to guide the water into the gutter even in an overhanging manner and to avoid dripping beforehand. According to the invention, the gutter belly, which refers to the section of the gutter that can be filled with water when the side wall is aligned vertically, is connected to a feed section that encompasses the recess in the side wall, wherein the surface tension of the water is sufficient to guide water in an overhanging manner into the gutter belly.

Der Zuführabschnitt ist oberhalb des Rinnenbauchs angeordnet ist und den Rinnenbauch mit der Seitenwand verbindet.The feed section is arranged above the gutter belly and connects the gutter belly with the side wall.

Die Rinne ist unterhalb einer Verdampferfläche angeordnet, vorzugsweise in der Seitenwand unterhalb eines mit dem Verdampfer zusammenwirkenden Bereichs der Seitenwand.The channel is arranged below an evaporator surface, preferably in the side wall below a region of the side wall interacting with the evaporator.

Dies ist von Vorteil, da im Bereich des Verdampfers oftmals eine Tauwasserbildung ansetzt, bzw. eine Vereisung der Innenfläche stattfindet. Bei einem semiautomatischen oder automatischen Abtauvorgang fällt dann unterhalb dieses Bereichs Tauwasser an.This is an advantage because condensation often begins to form in the area of the evaporator, or the inner surface becomes icy. During a semi-automatic or automatic defrosting process, condensation then forms below this area.

Weiter ist vorgesehen, dass die Rinne umlaufend im Inneren der Kühl- und/oder Gefriertruhe vorgesehen ist. Vorzugsweise ist die Rinne Teil einer Bodenwanne eines truhenförmigen Kühl- und/oder Gefriergeräts. Dies kann zu merklichen Bauteileinsparungen führen, da die Ausbildung der Rinne einteilig mit der Bodenwanne erfolgen kann. Als Herstellverfahren bietet sich dabei das Kunststoff- Vakuum-Tiefziehverfahren an.It is also intended that the channel is provided all the way around the interior of the refrigerator and/or freezer. The channel is preferably part of a base pan of a chest-shaped refrigerator and/or freezer. This can lead to significant savings in components, as the channel can be formed as one piece with the base pan. The plastic vacuum deep-drawing process is a suitable manufacturing process.

Es ist jedoch auch möglich, dass die Rinne ein eigenständiges Bauteil ist oder aus mehreren Bauteilen zusammenzufügen ist.However, it is also possible that the gutter is an independent component or is assembled from several components.

Die Erfindung betrifft ferner ein Verfahren zur Herstellung eines Kühl- und/oder Gefriergeräts nach einem der vorhergehenden Ansprüche, wobei die Rinne zusammen mit einer Bodenwanne in einem Tiefziehverfahren, vorzugsweise einem Kunststoff-Vakuum-Tiefziehverfahren erfolgt.The invention further relates to a method for producing a refrigerator and/or freezer according to one of the preceding claims, wherein the channel is produced together with a base pan in a deep-drawing process, preferably a plastic vacuum deep-drawing process.

Further features, details and advantages of the invention will become apparent from the following description of the figures. They show:

Fig. 1 zeigt eine perspektivische Ansicht einer erfindungsgemäßen Kühl- und/oder Gefriertruhe 1, das über einen truhenförmigen Korpus 2 verfügt. Dabei ist das Verschlusselement zum Verschließen der Kühl- und/oder Gefriertruhe 1 nicht dargestellt, um einen Blick in das Innere des Geräts 1 nicht zu behindern. Man erkennt eine Seitenwand 21, die durch eine Rinne 3 in zwei Abschnitte unterteilt wird. Fig.1 shows a perspective view of a refrigerator and/or freezer 1 according to the invention, which has a chest-shaped body 2. The closure element for closing the refrigerator and/or freezer 1 is not shown in order not to obstruct a view into the interior of the device 1. A side wall 21 can be seen, which is divided into two sections by a groove 3.

Fig. 2 ist eine andere Perspektivansicht der Kühl- und/oder Gefriertruhe 1, die einen anderen Blick in das Innere der Kühl- und/oder Gefriertruhe 1 erlaubt. Man erkennt, dass die Rinne 3 zum Ansammeln und Abführen von Tauwasser umlaufend in dem truhenförmigen Korpus 2 angeordnet ist. Dabei ist die Rinne 3 typischerweise unterhalb von Verdampferelementen angeordnet, da sich an der Innenseite des Korpus 2 auf Höhe der Verdampferelemente (nicht dargestellt) die Bildung von Tauwasser verstärkt auftritt. Fig.2 is another perspective view of the refrigerator and/or freezer 1, which allows a different view of the interior of the refrigerator and/or freezer 1. It can be seen that the channel 3 for collecting and draining condensate is arranged all around the chest-shaped body 2. The channel 3 is typically arranged below evaporator elements, since the formation of condensate occurs more frequently on the inside of the body 2 at the level of the evaporator elements (not shown).

Weiter erkennt man an einem der schmalen Enden der truhenförmigen Form der Kühl- und/oder Gefriertruhe 1 eine in den Innenraum stehende Einwölbung 4, die einen Raum zum Anordnen von Teilen des Kühlkreislaufes abdeckt. Eine Luftzufuhr zum Kühlen dieser unter der Einwölbung 4 angeordneten Aggregatsteile wird durch das Luftgitter 5 sichergestellt.Furthermore, at one of the narrow ends of the chest-shaped form of the refrigerator and/or freezer 1, a bulge 4 protruding into the interior can be seen, which covers a space for arranging parts of the cooling circuit. An air supply for cooling these parts of the unit arranged under the bulge 4 is ensured by the air grille 5.

Fig. 3 zeigt einen Querschnitt der erfindungsgemäßen Kühl- und/oder Gefriertruhe 1. Der Korpus 2 verfügt dabei an seiner Innenseite über Seitenwände 21, sowie eine Bodenwanne 22. Der Übergang von der Bodenwanne 22 zu der Seitenwand 21 ist bündig ausgeführt und kann je nach Ausführungsform oberhalb oder auch unterhalb der Rinne 3 erfolgen. In der dargestellten Ausführungsform ist die Rinne 3 einteilig mit der Bodenwanne 22 gebildet. Die Herstellung der Bodenwanne bzw. der Rinne 3 kann dabei mit einem Tiefziehverfahren, insbesondere einem Kunststoff-Vakuum-Tiefziehverfahren durchgeführt werden. Fig.3 shows a cross-section of the refrigerator and/or freezer 1 according to the invention. The body 2 has side walls 21 on its inside and a base pan 22. The transition from the base pan 22 to the side wall 21 is flush and can be above or below the channel 3 depending on the embodiment. In the embodiment shown, the channel 3 is formed in one piece with the base pan 22. The base pan or the channel 3 can be manufactured using a deep-drawing process, in particular a plastic vacuum deep-drawing process.

Man erkennt, dass die Rinne 3 gegenüber einer durch die Seitenwand definierten planaren Ebene vertieft angeordnet ist. Die Rinne 3 könnte als nutartige Ausnehmung gegenüber der planaren Ebene, die durch die Seitenwand 21 definiert ist, angesehen werden.It can be seen that the channel 3 is recessed relative to a planar plane defined by the side wall. The channel 3 could be viewed as a groove-like recess relative to the planar plane defined by the side wall 21.

Fig. 4 zeigt eine vergrößerte Darstellung der Rinne aus der Fig. 3. Fig.4 shows an enlarged view of the channel from the Fig.3 .

Ausgehend von einer über der Rinne 3 angeordneten Seitenwand 21 erstreckt sich ein Vertiefungsabschnitt 32 aus der durch die Seitenwand 21 definierten Ebene hinaus. Dieser geht dann in den sogenannten Rinnenbauch über, der bei bestimmungsgemäßer Ausrichtung der Seitenwand 21 dazu ausgelegt ist, mit Wasser gefüllt zu werden, das aus dem Inneren des Geräts 1 nach Außen befördert wird. Die Seite des Rinnenbauchs 21, die den Zuführabschnitt 32 gegenüber steht, geht dann direkt in die unter der Rinne 3 angeordnete Seitenwand 21 über. Die nasenartige Einbuchtung, welche die Rinne 3 gegenüber der etwa planaren durch die Seitenwand 21 definierten Ebene darstellt, ist von senkrecht nach unten fallendend Schmutzpartikel geschützt. Auch vermindert sie nicht - anders als bisher bekannte Rinnen - die Innenabmessungen des mit der Rinne versehenden Korpus 2.Starting from a side wall 21 arranged above the channel 3, a recessed section 32 extends out of the plane defined by the side wall 21. This then merges into the so-called channel belly, which, when the side wall 21 is aligned as intended, is designed to be filled with water that is conveyed from the inside of the device 1 to the outside. The side of the channel belly 21 that is opposite the feed section 32 then merges directly into the side wall 21 arranged below the channel 3. The nose-like indentation that the channel 3 represents in relation to the approximately planar plane defined by the side wall 21 is protected from dirt particles falling vertically downwards. Nor does it reduce the internal dimensions of the body 2 provided with the channel - unlike previously known channels.
