Description
TECHNISCHES GEBIET DER ERFINDUNGTECHNICAL FIELD OF THE INVENTION
Die vorliegende Erfindung betrifft einen Kühlschrank; und insbesondere einen Kühlschrank mit Luftumgehungsdurchgängen, die es ermöglichen, daß Kühlluft darin zirkuliert, selbst wenn einige Abschnitte eines Verdunsters mit Frost bedeckt sind.The The present invention relates to a refrigerator; and particularly a fridge with air bypasses, which allow cooling air in it circulates even if some sections of an evaporator with Frost are covered.
STAND DER TECHNIKSTATE OF TECHNOLOGY
Im allgemeinen ist ein Kühlschrank mit einem Verdunster zum Kühlen von darin zu zirkulierender Luft ausgestattet. Nach längerer Benutzung bildet sich zwangsläufig Frost auf dem Verdunster.in the general is a fridge with a evaporator for cooling equipped with circulating air. After prolonged use inevitably forms Frost on the evaporator.
Falls sich zuviel Frost auf dem Verdunster bildet, verschlechtert sich dessen Kühlleistung und die Zirkulation der Kühlluft innerhalb des Kühlschranks wird auch durch den Frost, der die Luftdurchgänge blockiert, behindert.If too much frost forms on the evaporator worsens its cooling capacity and the circulation of cooling air inside the refrigerator is also hampered by the frost blocking the air passages.
Um den Verdunster zu entfrosten, wird der Kühlschrank herkömmlicherweise mit einem Entfrost-Modus versehen. Ob der Defrost-Modus aktiviert wird oder nicht, wird durch die Leistung bestimmt, die zum Antreiben eines Kompressors verbraucht wird und durch eine Änderung der Temperatur während des Antriebs des Kompressors.Around defrosting the evaporator, the refrigerator is conventional provided with a defrost mode. Whether the defrost mode is activated or not, is determined by the power required to drive a compressor is consumed and by a change the temperature during the drive of the compressor.
In dem herkömmlichen Kühlschrank wird jedoch gewöhnlich zuviel Frost auf dem Verdunster gebildet, bevor der Kühlschrank automatisch den Entfrost-Modus startet, was erst zu einem Blockieren der Kühlluftdurchgänge führt, und zu einer Leistungsverschlechterung des Kühlschranks.In the conventional one fridge but becomes common too much frost formed on the evaporator before the refrigerator automatically the defrost mode starts, resulting in a blockage the cooling air passages leads, and to a performance deterioration of the refrigerator.
Die US-A-5,826,441 und EP-A-0 592 004 zeigen einen Kühlschrank, der ein Gefrierfach mit einem Ventilator, ein Kühl fach mit einem Ventilator und einen Verdunster aufweist. Der Kühlschrank umfaßt einen ersten Durchgang, der durch eine Außenwand des Verdunsters und eine Platte gebildet ist, zum Durchströmen von Kühlluft vom Kühlfach zum Ventilator des Kühlfachs. Zudem ist ein zweiter Durchgang vorgesehen zum Durchströmen der Kühlluft vom Gefrierfach zum Ventilator des Gefrierfachs. Etwas von der durch diese Durchgänge fließenden Kühlluft kann möglicherweise nicht in Kontakt mit den Außenwänden des Verdunsters gelangen. Es besteht jedoch weiterhin eine Gefahr, daß diese Durchgänge durch große Mengen an Frost blockiert werden, die sich an den Außenwänden des Verdunsters bilden.The US-A-5,826,441 and EP-A-0 592 004 show a refrigerator having a freezer compartment with a fan, a refrigerated compartment with a fan and a vaporizer. The refrigerator includes one first passage, passing through an outer wall of the evaporator and a plate is formed for the passage of cooling air from the cooling compartment to Fan of the refrigerator compartment. In addition, a second passage is provided for flowing through the cooling air from the freezer to the fan of the freezer. Something of that through these passages flowing cooling air may possibly not in contact with the exterior walls of the Evaporator arrive. However, there is still a danger that these crossings through big ones Quantities of frost are blocked on the exterior walls of the Form evaporator.
OFFENBARUNG DER ERFINDUNGEPIPHANY THE INVENTION
Es ist daher ein primäres Ziel der vorliegenden Erfindung, einen Kühlschrank mit Luftumgehungsdurchgängen bereitzustellen, die es ermöglichen, daß Kühlluft darin zirkuliert, selbst wenn einige Abschnitte eines Verdunsters mit Frost bedeckt sind.It is therefore a primary one Object of the present invention to provide a refrigerator with air bypass passages, which make it possible that cooling air in it circulates even if some sections of an evaporator with Frost are covered.
Das obige Ziel der vorliegenden Erfindung wird erreicht, indem ein Kühlschrank bereitgestellt wird, der ein Gefrierfach mit einem Ventilator, ein Kühlfach mit einem Ventilator und einen Verdunster aufweist, wobei der Kühlschrank einen ersten Umgehungsdurchgang zum Durchströmen von Kühlluft vom Kühlfach direkt zum Ventilator des Kühlfachs umfaßt, wodurch der Kühlluft ermöglicht wird, den Verdunster zu umgehen; und einen zweiten Umgehungsdurchgang zum Durchströmen der Kühlluft vom Gefrierfach direkt zum Ventilator des Gefrierfachs, wodurch der Kühlluft ermöglicht wird, den Verdunster zu umgehen, wobei der erste Umgehungsdurchgang durch eine Platte, die vom Verdunster getrennt ist, und von der Rückwand des Kühlschranks gebildet wird.The The above object of the present invention is achieved by a refrigerator is provided, which has a freezer with a fan, a refrigerated compartment with a fan and a evaporator, the refrigerator a first bypass passage for flowing cooling air from the cooling compartment directly to the fan of the refrigerating compartment, whereby the cooling air allows is going to bypass the evaporator; and a second bypass passage to flow through the cooling air from Freezer compartment directly to the fan of the freezer, causing the cooling air allows is to bypass the evaporator, being the first bypass passage by a plate, which is separated from the evaporator, and by the rear wall of the refrigerator becomes.
KURZE BESCHREIBUNG DER ZEICHNUNGBRIEF DESCRIPTION OF THE DRAWING
Die obigen weiteren Ziele und Merkmale der vorliegenden Erfindung werden aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels mit Bezug auf die beigefügte Zeichnung deutlich, in der:The The above further objects and features of the present invention from the following description of a preferred embodiment with reference to the attached Drawing clearly, in the:
