Description
Kombinationskältegerät Combination refrigeration device
Die vorliegende Erfindung betrifft ein Haushaltskältegerät, und zwar insbesondere ein Kombinationskältegerät mit einem eine Kühlfachwanne und eine Gefrierfachwanne bildenden Innenbehälter, einem Kastenverdampfer, der die Gefrierfachwanne an vier Seiten umgibt, und einem Plattenverdampfer, der eine an einer Rückseite der The present invention relates to a household refrigerator, in particular a combination refrigerator with a cooling tank and a freezer compartment forming inner container, a box evaporator, which surrounds the freezer compartment trough on four sides, and a plate evaporator, one at a back of the
Kühlfachwanne angeordnete Platte umfasst. Refrigerator tray arranged plate comprises.
Ein solches Kältegerät ist aus DE202005000909U1 bekannt. Such a refrigeration device is known from DE202005000909U1.
Eine große Ausdehnung des Verdampfers ist insbesondere an einem Gefrierfach interessant, denn je größer die Verdampferfläche ist, umso kleiner kann die A large expansion of the evaporator is particularly interesting in a freezer, because the larger the evaporator surface, the smaller the can
Temperaturdifferenz zwischen dem Verdampfer und dem von ihm gekühlten Fach gemacht werden. Eine hohe Verdampfertemperatur verbessert den Wirkungsgrad des Geräts. Es ist daher an sich wünschenswert, auch die fünfte Seite einer Gefrierfachwanne kühlen zu können. Ein Umwickeln mit dem Kältemittelrohr wie an den ersten vier Seiten der Gefrierfachwanne ist an dieser fünften Seite jedoch nicht mehr möglich. Temperature difference between the evaporator and the compartment cooled by him be made. A high evaporator temperature improves the efficiency of the device. It is therefore desirable per se to be able to cool the fifth side of a freezer compartment tub. Wrapping with the refrigerant tube as on the first four sides of the freezer compartment is not possible on this fifth page.
Aufgabe der vorliegenden Erfindung ist daher, ein Kombinationskältegerät zu schaffen, das rationell zu fertigen ist und dabei eine Kühlung der Gefrierfachwanne an mehr als vier Seiten ermöglicht. The object of the present invention is therefore to provide a combination refrigeration device that is rational to manufacture and thereby allows cooling of the freezer compartment tub on more than four sides.
Die Aufgabe wird gelöst, indem eine zweite Platte des Plattenverdampfers, von dem bereits eine Platte die Rückseite der Kühlfachwanne kühlt, auch an einer Rückseite der Gefrierfachwanne angeordnet ist. Der Plattenverdampfer kann in einem Arbeitsgang an beiden Wannen gleichzeitig montiert werden, so dass der Fertigungsaufwand gegenüber dem herkömmlichen Kältegerät nur unwesentlich erhöht ist. The object is achieved by a second plate of the plate evaporator, of which a plate already cools the back of the refrigerating compartment, is also arranged on a rear side of the freezer compartment. The plate evaporator can be mounted in a single operation on both trays at the same time, so that the production cost compared to the conventional refrigeration device is only slightly increased.
Vorzugsweise ist der Plattenverdampfer als Tube-on-Sheet-Verdampfer ausgebildet. Dies vereinfacht die Herstellung einer das Kältemittel leitenden Verbindung zwischen den beiden Platten des Plattenverdampfers. Vorzugsweise erstreckt ein Kältemittelrohr des Plattenverdampfers sich einteilig über die erste und die zweite Platte, um eine Lötstelle zwischen den Platten und eine damit verbundene mögliche Undichtigkeit und den Arbeitsaufwand des Lötens zu vermeiden. Preferably, the plate evaporator is designed as a tube-on-sheet evaporator. This simplifies the production of a refrigerant-conducting connection between the two plates of the plate evaporator. Preferably, a refrigerant pipe of the plate evaporator integrally extends over the first and second plates to avoid soldering between the plates and associated possible leakage and the labor of soldering.
Eine Anschlussstelle zum Anschließen, insbesondere Anlöten, eines Rohrs des A connection point for connecting, in particular soldering, a pipe of
Kastenverdampfers ist vorzugsweise an einer zweiten Platte gebildet. So kann dasBox evaporator is preferably formed on a second plate. That's how it works
Kältemittelrohr des Kastenverdampfers unbehindert durch den Plattenverdampfer um die Gefrierfachwanne gewickelt und anschließend der Plattenverdampfer montiert und an den Kastenverdampfer angeschlossen werden. Die große Ausdehnung der Verdampferfläche an der Gefrierfachwanne erlaubt insbesondere einen Aufbau des Kältemittelkreislaufs, bei dem der Kastenverdampfer dem Plattenverdampfer vorgeschaltet ist. Refrigerant pipe of the box evaporator unhindered by the plate evaporator wrapped around the freezer compartment tub and then mounted the plate evaporator and connected to the box evaporator. The large extent of the evaporator surface on the freezer compartment tub allows in particular a structure of the refrigerant circuit, in which the box evaporator is connected upstream of the plate evaporator.
Wenn sich die Verdampfungstemperaturen des Kältemittels im Platten- und When the evaporation temperatures of the refrigerant in the plate and
Kastenverdampfer nicht wesentlich unterscheiden, genügt eine geringe Länge des Kältemittelrohrs auf der ersten Platte des Plattenverdampfers, um die Kühlfachwanne ausreichend zu kühlen. Um dennoch eine homogene Temperaturverteilung im Kühlfach zu erzielen, sollte die erste Platte dennoch einen Großteil der Rückseite der Do not significantly distinguish box evaporator, a small length of the refrigerant pipe on the first plate of the plate evaporator is sufficient to cool the refrigerator compartment well sufficient. Nevertheless, in order to achieve a homogeneous temperature distribution in the refrigerator compartment, the first plate should still a large part of the back of the
Kühlfachwanne bedecken. Deswegen ist zweckmäßigerweise das Kältemittelrohr auf der ersten Platte des Plattenverdampfers weniger dicht verlegt als auf der zweiten. Cover the refrigerator compartment. Therefore, the refrigerant tube is expediently less densely laid on the first plate of the plate evaporator than on the second.
