Abstract

Description
Die vorliegende Erfindung betrifft ein Kältegerät, insbesondere ein Haushaltskältegerät, mit einem Korpus und einer Tür, die eine Lagerkammer begrenzen, und mit einem Gebläse, das einen Zustrom von Kaltluft in die Lagerkammer über zwei in Seitenwänden des Korpus verlaufende Zuluftkanäle antreibt. Ein solches Kältegerät ist aus
Der Dichtungsbereich zwischen Korpus und Tür stellt herkömmlicher Weise den wichtigsten Einfallweg für Umgebungswärme in die Lagerkammer eines Kältegeräts dar. Dabei liefern die vertikal verlaufenden Bereiche der Dichtung den Hauptbeitrag, da hier eine an den Dichtungen entlang aufsteigende Konvektionsströmung für einen schnellen Wärmetransport ins Innere des Geräts sorgen kann. Indem Kaltluft von den Seitenwänden her in die Lagerkammer eingeblasen wird, kann für eine schnelle Neutralisierung dieser einströmenden Wärme gesorgt und der Temperaturgradient zwischen türnahen und rückwandnahen Bereichen der Lagerkammer gering gehalten werden. Problematisch hierbei ist jedoch, dass der Luftstrom eines Gebläses, um Zuluftkanäle in gegenüberliegenden Seitenwänden des Korpus zu versorgen, mehrfach umgelenkt werden muss. Dies führt zu hohen Strömungsverlusten. Ein Gebläsemotor, der die dafür erforderliche Antriebsleistung erbringt, produziert entsprechend viel Abwärme. Um den Aufbau des Geräts einfach zu halten, ist der Motor des Gebläses im Allgemeinen innerhalb eines wärmeisolierten Bereichs des Geräts angeordnet, so dass seine Abwärme sich in der Lagerkammer verteilt und die Energieeffizienz des Geräts beeinträchtigt.The sealing area between the body and door is traditionally the most important path of incidence for ambient heat in the storage chamber of a refrigeration device. The vertical areas of the seal provide the main contribution, since here on the seals along rising convection provide rapid heat transfer into the interior of the device can. By blowing in cold air from the side walls into the storage chamber, this incoming heat can be rapidly neutralized and the temperature gradient between regions of the storage chamber close to the door and near the back wall can be kept low. The problem here, however, is that the air flow of a fan to supply air ducts in opposite side walls of the body, must be redirected several times. This leads to high flow losses. A blower motor, which provides the necessary drive power, produces correspondingly much waste heat. In order to keep the design of the device simple, the motor of the fan is generally located within a heat-insulated area of the device so that its waste heat dissipates in the storage chamber and affects the energy efficiency of the device.
Aus
Aufgabe der Erfindung ist, ein Kältegerät mit einem Gebläse und türnahen Zuluftkanälen zu schaffen, das eine wirksame Luftumwälzung in der Lagerkammer bei geringer Leistung des Gebläses erreicht.The object of the invention is to provide a refrigeration device with a fan and near-door supply air ducts, which achieves effective air circulation in the storage chamber at low power of the blower.
Die Aufgabe wird gelöst, in dem bei einem Kältegerät mit einem Korpus und einer Tür, eine Lagerkammer begrenzend, und mit einem Gebläse, das ein Zustrom von Kaltluft in die Lagerkammer über zwei in Seitenwänden des Korpus vertikal verlaufende Zuluftkanäle antreibt, das Gebläse ein Radiallüfter ist und eine Drehachse des Radiallüfters im Wesentlichen vertikal ausgerichtet ist. Ein solcher Radiallüfter saugt in Richtung seiner Drehachse an und stößt die Luft in radialer Richtung, d. h. entsprechend der Ausrichtung der Lüfterachse im Wesentlichen horizontal aus, so dass eine einzige Umlenkung um ca. 90° genügt, um diese Luft in die Zuluftkanäle einzuspeisen.The object is achieved in which in a refrigerator with a body and a door, a storage chamber delimiting, and with a fan that drives an influx of cold air into the storage chamber via two in side walls of the body vertically extending Zuluftkanäle, the fan is a radial fan and an axis of rotation of the radial fan is oriented substantially vertically. Such a radial fan sucks in the direction of its axis of rotation and pushes the air in the radial direction, d. H. in accordance with the orientation of the fan axis substantially horizontally, so that a single deflection of about 90 ° is sufficient to feed this air into the supply air ducts.
Wenn die Zuluftkanäle sich in türnahen Bereichen der Seitenwände erstrecken, ist zweckmäßigerweise wenigstens ein Abluftkanal in einer Rückwand des Korpus oder in rückwandnahen Bereichen der Seitenwände vorgesehen, um einen Strom der Kaltluft durch die Lagerkammer in deren Tiefenrichtung zu erzwingen.When the supply air ducts extend in door-near regions of the side walls, at least one exhaust duct is expediently provided in a rear wall of the body or in regions of the side walls close to the back wall in order to force a flow of cold air through the bearing chamber in its depth direction.
Die Zuluftkanäle und wenigstens ein Abluftkanal sollten vertikal verteilte Austritts- bzw. Eintrittsöffnungen für die umgewälzte Luft aufweisen, um einen über die gesamte Höhe der Lagerkammer gleichmäßigen verteilten Luftstrom in Tiefenrichtung zu erzeugen und insbesondere um, wenn die Lagerkammer durch Fachböden oder dergleichen in Fächer unterteilt ist, einen solchen Luftstrom in jedem einzelnen Fach der Lagerkammer zu erzeugen.The supply air ducts and at least one exhaust air duct should have vertically distributed outlet or inlet openings for the circulated air in order to produce a distributed over the entire height of the storage chamber evenly distributed air flow in the depth direction and in particular to when the storage chamber is divided by shelves or the like into compartments to generate such airflow in each compartment of the storage chamber.
Eine den Radiallüfter aufnehmende und mit jedem Zuluftkanal kommunizierende Lüfterkammer ist zweckmäßigerweise zwischen der Decke des Korpus und der Lagerkammer angeordnet.A fan chamber accommodating the radial fan and communicating with each supply air duct is expediently arranged between the ceiling of the carcass and the storage chamber.
Einer ersten Ausgestaltung der Erfindung zu Folge kann die Lüfterkammer auch einen Verdampfer, insbesondere einen Lamellenverdampfer, zum Erzeugen der Kaltluft aufnehmen. Vorzugsweise ist der Verdampfer strömungsgünstig in einem rückwandnahen Bereich der Lüfterkammer angeordnet, während der Radiallüfter in einem türnahen Bereich der Lüfterkammer untergebracht ist.According to a first embodiment of the invention, the ventilating chamber can also accommodate an evaporator, in particular a laminar evaporator, for generating the cold air. Preferably, the evaporator is arranged aerodynamically in a region near the rear wall of the fan chamber, while the radial fan is accommodated in a region of the fan chamber close to the door.
Um die Umlenkung der Luft beim Übergang vom Verdampfer zum Radiallüfter zu minimieren, kann es zweckmäßig sein, wenn die Kammer zur Tür hin ansteigt.In order to minimize the deflection of the air in the transition from the evaporator to the radial fan, it may be useful if the chamber rises towards the door.
Einer zweiten Ausgestaltung zu Folge ist der Verdampfer in einer eigenen Verdampferkammer an der Rückwand des Korpus angeordnet.According to a second embodiment of the evaporator is arranged in a separate evaporator chamber on the rear wall of the body.
Hier ist es besonders strömungsgünstig, wenn die Drehachse des Lüfters mit der Verdampferkammer fluchtet, da der Lüfter so Luft aus der Verdampferkammer ohne Richtungswechsel ansaugen kann.Here it is particularly streamlined, when the axis of rotation of the fan is aligned with the evaporator chamber, as the fan so air can suck in from the evaporator chamber without changing direction.
Eine Wand, die die Lüfterkammer von der Lagerkammer trennt, ist hier vorzugsweise horizontal ausgerichtet. Dies erleichtert die Nutzung des obersten Fachs der Lagerkammer, da dessen Höhe in Tiefenrichtung des Korpus konstant bleiben kann.A wall which separates the fan chamber from the storage chamber is here preferably oriented horizontally. This facilitates the use of the top compartment of the storage compartment, since its height can remain constant in the depth direction of the carcass.
