Description

Die Erfindung betrifft einen Kühlschrank mit einem Kühlfach und einem Kaltlagerfach.The invention relates to a refrigerator with a cooling compartment and a cold storage compartment.

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.Refrigerator and freezer manufacturers strive to provide devices that optimally meet practical requirements. For this reason, combinations of devices are offered that have compartments with different temperatures, for example, refrigerated compartments with a temperature range of 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 produce the combination devices in such a cost-effective and economical manner that compartments of different temperatures are cooled by a common or coherent evaporator or a coherent cooling circuit. In addition, the devices should be economical, i. H. operate with low energy consumption.

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 to provide a refrigerator with a cooling compartment and a cold storage compartment, which can be produced inexpensively and operated in an economical manner.

Erfindungsgemäß wird diese Aufgabe gelöst durch einen Kühlschrank mit einem oberen Kühlfach und einem unteren Kaltlagerfach, die durch eine horizontale Zwischenwand voneinander getrennt sind, und mit mindestens einer diese verschließenden Tür oder Klappe, bei dem im oberen Bereich des Kühlfachs ein Kühlgebläse angeordnet und durch eine zu der Rückwand des Kühlfachs in etwa parallele Zwischenwand ein Kühlluftkanal abgeteilt ist, in dem sich ein Verdampfer befindet und der durch Durchbrüche im hinteren Bereich der Zwischenwand in das Kaltlagerfach mündet, bei dem im vorderen Bereich der Zwischenwand Durchbrüche und/oder ein Spalt zwischen der Zwischenwand und der Tür vorgesehen sind, durch die die Kühlluft in das Kühlfach eintritt und bei dem die Kälteverteilung durch die Laufzeit des Kompressors und/oder die Einschaltdauer (relative Laufzeit) und/oder die Drehzahl des Kühlgebläses gesteuert wird.According to the invention, this object is achieved by a refrigerator with an upper cooling compartment and a lower cold storage compartment, which are separated from one another by a horizontal partition, and with at least one door or flap closing them, in which a cooling fan is arranged in the upper region of the cooling compartment and by one the rear wall of the cooling compartment is divided into a roughly parallel intermediate wall, a cooling air duct in which there is an evaporator and which opens into the cold storage compartment through openings in the rear region of the intermediate wall, with openings and / or a gap between the intermediate wall and in the front region of the intermediate wall the door are provided, through which the cooling air enters the cooling compartment and in which the cold distribution is controlled by the running time of the compressor and / or the duty cycle (relative running time) and / or the speed of the cooling fan.

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 air stream cooling the cooling compartment and the cold storage compartment is cooled in the cooling air duct. This cooled cooling air flow then first enters the cold storage compartment, so that it is acted upon by colder air and is thereby cooled more than the cooling compartment into which the air emerging from the cold storage compartment enters.

Die Kühlleistung wird erfindungsgemäß 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.
According to the invention, 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 to be understood as the relative running time of the cooling fan, that is to say the ratio of the cooling fan's on times to the off times.
  • 3. Cooling fan speed
    The volume flow of the cooling air can be influenced by the speed of the cooling fan, 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, however, it is cooled less strongly than cooling air which sweeps over the evaporator with a reduced volume flow and can therefore assume lower temperatures due to its longer residence time.

Erfindungsgemäß 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.According to the invention, depending on the ambient temperature and the type of goods stored in the refrigerator, the parameters determining the temperature in the refrigerator compartment and in the cold storage compartment are coordinated in such a way that the desired temperatures prevail in both compartments, i.e. in the cold storage compartment a temperature of + 1 ° C. fluctuating temperature and in the refrigerator compartment a temperature in the range of 4 ° to 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 a temperature sensor is arranged in the cooling compartment and / or in the cold storage compartment. These temperature sensors measure the temperatures and emit signals corresponding to the measured temperatures to an electronic computing unit (microcomputer) which, based on 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 parameters to be controlled can take place empirically or else mathematically.

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 wall is to be empirically or mathematically adapted to the cooling requirements of the cooling compartment and the cold storage compartment.

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 arranged freely suspended in the cooling air duct. The evaporator can also be foamed behind the rear wall of the refrigerator compartment.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung, in deren einziger Figur ein Vertikalschnitt durch einen Kühlschrank dargestellt ist, näher erläutert.An embodiment of the invention is explained below with reference to the drawing, in the single figure of which a vertical section through a refrigerator is shown.

Der Kühlschrank besteht aus einem Korpusteil 1 mit einer Rückwand 2, einer Deckwand 3 und Zwischenwänden 4, 5. Die Zwischenwand 4 trennt ein oberes Kühlfach 6 von einem unteren Kaltlagerfach 7. Unter der Zwischenwand 5 kann noch ein Gefrierfach angeordnet sein, daß jedoch vorliegend nicht zur Erfindung gehört und daher außer Betracht gelassen wird. Der das Kühlfach 6 und das Kaltlagerfach 7 enthaltende Korpusteil ist durch eine übliche Tür 8 verschließbar. Etwa parallel zur Rückwand 2 ist eine isolierende Zwischenwand 9 angeordnet, die von dem Kühlfach 6 einen Kühlluftkanal 10 abteilt. Der Kühlluftkanal 10 verbreitert sich in seinem unteren Bereich in Richtung auf die Zwischenwand 4 durch die dargestellte Schrägstellung des unteren Teils der Zwischenwand 9. Im hinteren Bereich der oberen Deckwandung 3 ist ein Kühlgebläse 11 angeordnet, dessen Austrittsöffnung bzw. Austrittsspalt 12 in den Kühlluftkanal 10 mündet.The refrigerator consists of a body part 1 with a rear wall 2, a top wall 3 and intermediate walls 4, 5. The intermediate wall 4 separates an upper cooling compartment 6 from a lower cold storage compartment 7. A freezer compartment can also be arranged under the intermediate wall 5, but not in the present case belongs to the invention and is therefore disregarded. The body part containing the cooling compartment 6 and the cold storage compartment 7 can be closed by a conventional door 8. An insulating intermediate wall 9 is arranged approximately parallel to the rear wall 2 and divides a cooling air duct 10 from the cooling compartment 6. The cooling air duct 10 widens in its lower region in the direction of the intermediate wall 4 due to the inclined position of the lower part of the intermediate wall 9 shown .

In dem Kühlluftkanal 10 ist frei hängend ein Verdampfer 13 angeordnet. Am unteren Ende des Kühlluftkanals 10 ist eine Rinne 14 vorgesehen, die der Sammlung von von dem Verdampfer abtropfenden Wasser dient.An evaporator 13 is freely suspended in the cooling air duct 10. At the lower end of the cooling air duct 10, a channel 14 is provided, which is used to collect water dripping from the evaporator.

Die Zwischenplatte 4 ist an ihrem hinteren Endbereich im Mündungsbereich des Kühlluftkanals 10 mit einem Spalt oder Durchbrüchen 15 versehen, durch die der Kühlluftstrom 16, der durch die Pfeile angedeutet ist, in das Kaltlagerfach 7 eintritt. In dem Kaltlagerfach unterteilt sich der Kühlluftstrom in der durch die Pfeile 17 angegebenen Weise. In dem Kaltlagerfach 7 können Schubfächer 18 angeordnet sein, die dann in der dargestellten Weise von dem Kühlluftstrom 17 bestrichen werden.The intermediate plate 4 is provided at its rear end region in the mouth region of the cooling air duct 10 with a gap or openings 15 through which the cooling air flow 16, which is indicated by the arrows, enters the cold storage compartment 7. In the cold storage compartment, the cooling air flow is divided in the manner indicated by the arrows 17. Drawers 18 can be arranged in the cold storage compartment 7, which are then swept by the cooling air flow 17 in the manner shown.

Die Zwischenplatte 4 ist in ihrem vorderen Bereich mit Spalten oder Durchbrüchen 19 versehen, durch die der Kühlluftstrom in Richtung des Pfeils 20 in das Kühlfach 6 eintritt. Der aus dem Kaltlagerfach austretende Kühlluftstrom überstreicht sodann das Kühlfach 6 und kühlt dieses in der gewünschten Weise. Der Kühlluftstrom tritt sodann in die Saugseite des Kühlgebläses ein und wird anschließend in dem Kühlluftkanal 10 erneut gekühlt.The intermediate plate 4 is provided in its front area with gaps or openings 19 through which the cooling air flow enters the cooling compartment 6 in the direction of the arrow 20. The cooling air stream emerging from the cold storage compartment then sweeps over the cooling compartment 6 and cools it in the desired manner. The cooling air flow then enters the suction side of the cooling fan and is then cooled again in the cooling air duct 10.

In dem Kühlfach können in der dargestellten Weise Ablageplatten und eine Schublade angeordnet sein. An der Tür können die üblichen Ablagefächer befestigt sein.Storage plates and a drawer can be arranged in the refrigerator compartment in the manner shown. The usual storage compartments can be attached to the door.

Die Steuereinrichtung zur Steuerung der Einschaltzeiten des Kompressors und des Kühlgebläses sowie zur Steuerung der Drehzahl des Kühlgebläses ist nicht dargestellt. Diese ist jedoch empirisch oder rechnerisch so einzustellen, daß das Kaltlagerfach und das Kühlfach von einem Kühlluftstrom mit einer Geschwindigkeit und einer Temperatur durchströmt wird, die die gewünschte Temperaturverteilung gewährt.The control device for controlling the switch-on times of the compressor and the cooling fan and for controlling the speed of the cooling fan is not shown. However, this is to be set empirically or arithmetically in such a way that a flow of cooling air flows through the cold storage compartment and the cooling compartment at a speed and a temperature which ensures the desired temperature distribution.

Weiterhin sind die Isolierungen der Wandungen des Korpusteils, der Zwischenwände und der Tür so zu wählen, daß bei geringem Kälteverlust die optimale Temperaturverteilung erreicht wird.Furthermore, the insulation of the walls of the body part, the partitions and the door should be selected so that the optimum temperature distribution is achieved with little loss of cold.

Auch die Größe der Durchbrüche bzw. Durchtrittsspalte 15, 19 in der Zwischenwand 4 ist entsprechend der gewünschten Temperaturverteilung einzurichten.The size of the openings or passage gaps 15, 19 in the intermediate wall 4 must also be set up in accordance with the desired temperature distribution.
