Ein Verteilerkanal, der sich stromabwärts von dem Axialgebläse entlang der angrenzenden Wand erstreckt, weist eine in Richtung des vom Axialgebläse angetriebenen Luftstroms zunehmende Breite auf.A refrigerator has an evaporator disposed on a rear wall of a storage compartment and an axial fan disposed in a corner between the rear wall and an adjacent wall, the axis of which is oriented substantially parallel to the adjacent wall. A distribution channel extending downstream of the axial fan along the adjacent wall has an increasing width in the direction of the air flow driven by the axial fan.
Description
Die vorliegende Erfindung betrifft ein Kältegerät, insbesondere ein Haushaltskältegerät, bei dem ein Gebläse zur Homogenisierung der Temperaturverteilung in einem Lagerfach des Kältegeräts vorgesehen ist.The The present invention relates to a refrigerator, in particular a domestic refrigerator, in which a fan for homogenizing the temperature distribution in a storage compartment provided the refrigerator is.
Wenn an einem Rückwandverdampfer des Lagerfachs abgekühlte Luft abwärts fließt, ergibt sich eine Temperaturschichtung, bei der am Boden des Lagerfachs deutlich niedrigere Temperaturen herrschen als an der Decke. Um sicherzustellen, dass eine maximale gewünschte Lagertemperatur auch an der Decke nicht überschritten wird, muss die Bodenregion des Lagerfachs auf eine deutlich tiefere Temperatur abgekühlt werden. Die benötigte Kühlleistung wächst mit der zur Umgebung aufrechtzuerhaltenden Temperaturdifferenz. Eine effiziente Luftumwälzung, bei der keine Teile des Lagerfachs ausgespart bleiben, ist daher wünschenswert, um eine Temperaturschichtung zu verhindern und dadurch einen energieeffizienten Betrieb des Kältegeräts zu ermöglichen.If on a back wall evaporator the storage compartment cooled Air downwards flows, results in a temperature stratification, at the bottom of the storage compartment significantly lower temperatures prevail than on the ceiling. Around Ensure a maximum desired storage temperature as well not exceeded on the ceiling The bottom area of the storage compartment must be at a much deeper level Temperature cooled become. The needed Cooling power grows with you the temperature difference to be maintained to the environment. A efficient air circulation, at the absence of parts of the storage compartment is therefore desirable, to prevent temperature stratification and thereby an energy efficient To allow operation of the refrigerator.
Herkömmliche Kältegeräte verwenden zum Antreiben der Luftumwälzung häufig ein Axialgebläse, das in einer Ecke zwischen der Rückwand und einer daran angrenzenden Wand des Lagerfachs angeordnet ist und einen Luftstrom entlang dieser angrenzenden Wand antreibt. Die Abmessungen eines solchen Axialgebläses sind in Breitenrichtung der angrenzenden Wand im Wesentlichen die gleichen wie quer dazu und notwendigerweise wesentlich kleiner als die Breite der Rückwand und der angrenzenden Wand. Es ist daher nicht möglich, mit einem einzigen Axialgebläse einen gleichmäßig über die gesamte Breite der angrenzenden Wand verteilten Luftstrom anzutreiben. Daher existieren stets Randzonen des Lagerfachs, die schlecht an den Luftstrom des Gebläses angekoppelt sind und daher relativ schlecht gekühlt werden.conventional Use refrigeration equipment for driving the air circulation often an axial fan, that in a corner between the back wall and an adjacent wall of the storage compartment is arranged and drives an airflow along this adjacent wall. The Dimensions of such axial fan are in the width direction the adjacent wall is essentially the same as across it and necessarily much smaller than the width of the rear wall and the adjacent wall. It is therefore not possible with a single axial fan one evenly over the Whole width of the adjacent wall distributed airflow to power. Therefore, there are always marginal zones of the storage compartment, the poor at the airflow of the blower are coupled and therefore relatively poorly cooled.
Aufgabe der vorliegenden Erfindung ist, ein Kältegerät zu schaffen, das mit einfachen Mitteln eine gute Homogenität der Temperaturverteilung im Lagerfach erzielt.task The object of the present invention is to provide a refrigeration device that is simple Means a good homogeneity achieved the temperature distribution in the storage compartment.
Die Aufgabe wird gelöst, indem bei einem Kältegerät, insbesondere Haushaltskältegerät, mit wenigstens einem durch eine Tür zugänglichen Lagerfach, an dessen Rückwand ein Verdampfer vorgesehen ist, der von einem Gebläse mit Luft beaufschlagt ist, die über eine Luftführung in Richtung der Tür geleitet ist, die Luftführung als dem Verdampfer stromabwärts nachgelagerter Verteilerkanal ausgebildet ist, der eine von seiner Einströmöffung zu seiner zur Tür gerichteten Ausblasöffnung hin zunehmende Breite aufweist.The Task is solved by a refrigeration device, in particular Household refrigeration appliance, with at least one through a door accessible Storage compartment, at the rear wall An evaporator is provided by a blower with air which is over a air duct in the direction of the door is directed, the air duct downstream of the evaporator Downstream distribution channel is formed, one of his Inflow opening to his to the door directed exhaust opening has increasing width.
Bevorzugt nimmt die Breite des Verteilerkanals zur Ausblasöffnung hin zumindest weitgehend kontinuierlich zu. Damit sind als seitliche Begrenzungswände für den Verteilerkanal geradlinig verlaufende Seitenwände einsetzbar.Prefers takes the width of the distribution channel to the exhaust opening at least substantially continuously to. This is as a lateral boundary walls for the distribution channel straight running side walls used.
Besonders bevorzugt nimmt die Breite des Verteilerkanals beidseitig zumindest annähernd gleichmäßig zu. Hierdurch ist eine besonders einfache Fertigung des Verteilerkanals möglich.Especially Preferably, the width of the distribution channel takes at least on both sides almost equally. This is a particularly simple production of the distribution channel possible.
Um eine Luftumwälzung auf der gesamten Breite des Lagerfachs anzutreiben, ist bevorzugt, dass der Verteilerkanal an einem stromabwärtigen Ende die gesamte Breite des Lagerfachs ausfüllt.Around an air circulation to drive on the entire width of the storage compartment, it is preferred that the distribution channel at a downstream end the entire width of the storage compartment.
Für eine gleichmäßige Verteilung des Luftstroms über den Querschnitt des Verteilerkanals ist es zweckmäßig, wenn divergente Führungsrippen im Verteilerkanal angeordnet sind.For an even distribution the air flow over the cross section of the distribution channel, it is useful if divergent guide ribs are arranged in the distribution channel.
Der Verteilerkanal erstreckt sich zweckmäßigerweise über eine an die Rückwand angrenzende Wand des Lagerfachs.Of the Distribution channel expediently extends over a wall adjacent to the rear wall of the storage compartment.
Um eine gleichmäßige Verteilung des Luftdurchsatzes über die gesamte Breite des Verteilerkanals an seinem stromabwärtigen Ende zu erreichen, sollte der Winkel, in dem Seitenwände des Kanals divergieren, möglichst klein sein. Daher erstreckt sich der Verteilerkanal vorzugsweise bis zu einem vorderen Rand der angrenzenden Wand.Around a uniform distribution the air flow over the entire width of the distribution channel at its downstream end to reach, the angle at which side walls of the channel diverge, preferably be small. Therefore, the distribution channel preferably extends up to a front edge of the adjacent wall.
Im Allgemeinen wird die angrenzende Wand eine Decke des Lagerfachs sein.in the Generally, the adjacent wall becomes a ceiling of the storage compartment be.
Der Verteilerkanal ist zweckmäßigerweise durch eine Schale begrenzt, die die an die Rückwand angrenzende Wand überdeckt.Of the Distribution channel is conveniently through delimiting a shell that covers the wall adjacent to the back wall.
Führungsrippen können vorteilhaft an dieser Schale ausgebildet sein.guide ribs can be advantageously formed on this shell.
Um den Luftstrom am stromabwärtigen Ende des Verteilerkanals abzulenken, hat die angrenzende Wand vorzugsweise an ihrem vorderen Rand einen in das Lagerfach vorspringenden Steg, und eine langgestreckte Austrittsöffnung des Kanals ist einerseits durch den Steg und andererseits durch einen vorderen Rand der Schale begrenzt.Around the airflow at the downstream To divert the end of the distribution channel, the adjacent wall has preferably at its front edge a web projecting into the storage compartment, and an elongated outlet opening of the channel is on the one hand through the bridge and on the other hand through a front edge of the shell limited.
Die Schale kann an der angrenzenden Wand mit Hilfe von über ihren vorderen Rand überstehenden Fingern befestigt sein. Diese sind im Allgemeinen gut zugänglich und können gelöst werden, wenn es erforderlich ist, die Schale zu demontieren und auf das von ihr verdeckte Gebläse zuzugreifen.The Shell can be attached to the adjacent wall with the help of over her protruding from the front edge Be attached to fingers. These are generally accessible and accessible can solved if necessary, disassemble the shell and on the blower hidden by her access.
Damit das Gebläse wirksam Kaltluft ansaugen kann, ist vorzugsweise dem Gebläse ein Ansaugspalt vorgelagert, der auf einer Seite durch den Verdampfer begrenzt ist.In order for the blower can effectively suck cold air, preferably the blower upstream of a suction, which on one side by the Evaporator is limited.
Eine dem Verdampfer gegenüber liegende Seite des Ansaugspalts kann durch eine Rückwand einer in dem Lagerfach platzierten Schublade gebildet sein.A opposite the evaporator lying side of the suction gap can through a rear wall of a be placed in the storage compartment drawer.
Vorzugsweise handelt es sich bei dem Lagerfach um ein Null-Grad-Fach in einem Kombinations-Kältegerät.Preferably If the storage compartment is a zero-degree compartment in one Combination refrigeration device.
