Description

Die Erfindung betrifft einen Kühlschrank nach dem Oberbegriff des Anspruchs 1.The invention relates to a refrigerator according to the preamble of claim 1.

Aus EP-A 0 532 870 ist ein Kühlschrank dieser Art mit einem im oberen Bereich des oberen Fachs angeordneten Kühlgebläse bekannt, das sich im Einlaufbereich von Luftkanälen befindet, die durch eine Zwischenwand von dem oberen Fach abgeteilt sind. Die Zwischenwand verläuft parallel zu einem Verdampfer, der an der Rückwand des oberen Fachs angeordnet ist und dessen volle Breite einnimmt. Auf der Rückseite der Zwischenwand sind durch rippenartige Stege Luftkanäle abgeteilt, von denen die oberen Luftkanäle in seitlichen Austrittsöffnungen in der Zwischenwand münden, die sich etwa in Höhe des Kühlgebläses befinden. Die unteren Luftkanäle münden im Bereich des unteren Endes des Verdampfers und vermögen dadurch einen Schubkasten zu umströmen, der sich in dem unteren Fach befindet. Bei dem bekannten Kühlschrank ist die Luftführung über den Verdampfer so gestaltet, daß ohne Verlust an Nutzraum auch im vollbeladenen Zustand des Kühlschranks überall ein nahezu gleiches Temperaturniveau eingehalten werden kann.From EP-A 0 532 870 is a refrigerator of this type with one in the upper area of the Known upper compartment arranged cooling fan, which is in the inlet area of Air channels are located, which are partitioned by an intermediate wall from the upper compartment are. The intermediate wall runs parallel to an evaporator, which is on the rear wall the upper compartment is arranged and occupies its full width. On the back side the intermediate wall are divided by rib-like webs air channels, one of which the upper air ducts in side openings in the partition open, which are approximately at the level of the cooling fan. The lower air ducts open in the area of the lower end of the evaporator and are therefore capable of one To flow around the drawer, which is located in the lower compartment. In which known refrigerator, the air flow through the evaporator is designed so that everywhere without loss of usable space even when the refrigerator is fully loaded an almost identical temperature level can be maintained.

Die GB-A-1 485 666 zeigt dagegen einen Kühlschrank mit einem Kalt- und Kühllager fach, wobei ein Verdampfer im Kaltleger fach angeordnet ist und ein Luftstrom von dort über einen Schacht in der Rückwand in das darüber liegende Kühllager fach geführt wird.GB-A-1 485 666, on the other hand, shows a refrigerator with a cold and cold storage compartment, being a Evaporator is arranged in the cold lay compartment and an air flow from there over a shaft in the Rear wall in the cold storage compartment above to be led.

Es ist ein Bestreben von Kühl- und Gefriergeräteherstellern, Geräte zur Verfügung zu stellen, die in optimaler Weise den Anforderungen der Praxis gerecht werden. Aus diesem Grunde werden Kombinationen von Geräten angeboten, die Fächer mit unterschiedlichen Temperaturen aufweisen, beispielsweise Kühlfächer mit einem Temperaturbereich von 2° bis 9° C, Gefrier- oder Tiefkühlfächer und/oder Kaltlagerfächer mit Temperaturen von -2° bis +3° C.It is an effort by refrigerators and freezers manufacturers, appliances to make available that best meet the requirements do justice to practice. For this reason, combinations offered by devices with different subjects Have temperatures, for example, cooling compartments with a Temperature range from 2 ° to 9 ° C, freezer or freezer compartments and / or cold storage compartments with temperatures from -2 ° to + 3 ° C.

Weiterhin ist es ein Bestreben, die Kombinationsgeräte derart kostengünstig und in wirtschaftlicher Weise herzustellen, daß Fächer unterschiedlicher Temperaturen durch einen gemeinsamen oder zusammenhängenden Verdampfer oder einen zusammenhängenden Kühlkreislauf gekühlt werden. Zusätzlich sollen sich die Geräte wirtschaftlich, d. h. mit geringem Energieverbrauch betreiben lassen.Furthermore, it is an endeavor to use the combination devices in this way produce inexpensively and economically that Subjects of different temperatures through a common or coherent evaporator or a coherent Cooling circuit to be cooled. In addition, the devices should economical, d. H. operate with low energy consumption to let.

Aufgabe der Erfindung ist es daher, einen Kühlschrank mit einem Kühlfach und einem Kaltlagerfach zu schaffen, der sich kostengünstig herstellen und in wirtschaftlicher Weise betreiben läßt. The object of the invention is therefore a refrigerator with a To create a refrigerator compartment and a cold storage compartment, which is inexpensive manufacture and operate in an economical manner.

Erfindungsgemäß wird diese Aufgabe gelöst durch die Merkmale des Anspruchs 1.According to the invention, this object is achieved by the features of claim 1.

Bei dem erfindungsgemäßen Kühlschrank wird der das Kühlfach und das Kaltlagerfach kühlende Luftstrom in dem Kühlluftkanal gekühlt. Dieser gekühlte Kühlluftstrom tritt dann zunächst in das Kaltlagerfach ein, so daß dieses mit kälterer Luft beaufschlagt wird und dadurch stärker gekühlt wird als das Kühlfach, in das die aus dem Kaltlagerfach austretende Luft eintritt.In the refrigerator according to the invention, the refrigerator compartment and the cooling air stream cooled the cold storage compartment in the cooling air duct. This cooled cooling air flow then first enters the Cold storage compartment so that it is charged with colder air and is thereby cooled more than the refrigerator compartment in which the air escaping from the cold storage compartment.

Die Kühlleistung wird durch folgende Parameter beeinflußt:

  • 1. Laufzeit des Kompressors Von der Laufzeit des Kompressors hängt die durch den Verdampfer zur Verfügung gestellte Kälteleistung ab, die von dem über dem Verdampfer durch den Kühlluftkanal strömenden Kühlluftstrom abgenommen wird.
  • 2. Einschaltdauer des Kühlgebläses Unter der Einschaltdauer ist die relative Laufzeit des Kühlgebläses zu verstehen, also das Verhältnis der Einschaltzeiten des Kühlgebläses zu den Ausschaltzeiten.
  • 3. Drehzahl des Kühlgebläses Durch die Drehzahl des Kühlgebläses läßt sich der Volumenstrom der Kühlluft beeinflussen, wobei bei hoher Drehzahl von dem Kühlluftstrom eine große Kälteleistung von dem Verdampfer abgenommen wird. Aufgrund des hohen Volumendurchsatzes der Kühlluft wird diese aber weniger stark gekühlt als eine Kühlluft, die mit verringertem Volumenstrom über den Verdampfer streicht und daher aufgrund ihrer längerer Verweildauer tiefere Temperaturen annehmen kann.
    • The cooling capacity is influenced by the following parameters:
  • 1. Running time of the compressor The cooling capacity provided by the evaporator depends on the running time of the compressor and is taken from the cooling air flow flowing over the evaporator through the cooling air duct.
  • 2. Duty cycle of the cooling fan The duty cycle is the relative running time of the cooling fan, that is, the ratio of the cooling fan's on times to the off times.
  • 3. Speed of the cooling fan The speed of the cooling fan can influence the volume flow of the cooling air, with a high cooling capacity being taken from the evaporator at high speed from the cooling air flow. Due to the high volume throughput of the cooling air, it is cooled less strongly than a cooling air that sweeps over the evaporator with a reduced volume flow and can therefore reach lower temperatures due to its longer residence time.

    • In einer Ausgestaltung der Erfindung werden je nach der Umgebungstemperatur und der Art des in dem Kühlschrank gelagerten Guts die die Temperatur im Kühlfach und im Kaltlagerfach bestimmenden Parameter in der Weise aufeinander abgestimmt, daß in beiden Fächern die gewünschten Temperaturen herrschen, also in dem Kaltlagerfach eine um +1° C schwankende Temperatur und in dem Kühlfach eine im Bereich von 4° bis 9° C liegende Temperatur.In one embodiment of the invention, depending on the ambient temperature and the Type of goods stored in the refrigerator, which the temperature in the Refrigerator compartment and parameters defining the cold storage compartment in the way coordinated that the desired in both subjects Temperatures prevail, i.e. in the cold storage compartment around + 1 ° C fluctuating temperature and in the refrigerator compartment in the range of Temperature between 4 ° and 9 ° C.

    In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß in dem Kühlfach und/oder in dem Kaltlagerfach ein Temperaturfühler angeordnet ist. Diese Temperaturfühler messen die Temperaturen und geben den gemessenen Temperaturen entsprechende Signale an eine elektronische Recheneinheit (Mikrocomputer) ab, die aufgrund entsprechender Steuerprogramme zur Aufrechterhaltung der gewünschten Temperaturen die Laufzeit des Kompressors, die relative Einschaltdauer des Ventilators und die Drehzahl des Ventilators entsprechend steuert. Die Abstimmung dieser zu steuernden Parameter aufeinander kann empirisch oder aber auch rechnerisch erfolgen.In a further embodiment of the invention it is provided that in a temperature sensor in the cooling compartment and / or in the cold storage compartment is arranged. These temperature sensors measure the temperatures and give signals corresponding to the measured temperatures an electronic arithmetic unit (microcomputer), which due to appropriate control programs to maintain the desired temperatures, the running time of the compressor, the relative Duty cycle of the fan and the speed of the fan controls accordingly. The coordination of these to be controlled Parameters on each other can be empirical or also arithmetic respectively.

    Die Größe der Durchbrüche in der Zwischenwand ist empirisch oder rechnerisch dem Kältebedarf des Kühlfachs und des Kaltlagerfachs anzupassen.The size of the openings in the partition is empirical or arithmetically the cooling requirements of the refrigerator compartment and the cold storage compartment adapt.

    Zweckmäßigerweise ist der Verdampfer frei hängend in dem Kühlluftkanal angeordnet. Der Verdampfer kann aber auch hinter der Rückwand des Kühlfachs eingeschäumt sein.The evaporator is expediently suspended in the cooling air duct arranged. The evaporator can also behind the Foam back wall of the refrigerator compartment.
