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 \° bis IS^" C, Gefrier- oder Tiefkühlfächer und/oder Kaltlagerfächer mit Temperaturen von -2° bis +3° C.Refrigerator and freezer manufacturers strive to provide appliances that optimally meet practical requirements. For this reason, combinations of appliances are offered that have compartments with different temperatures, for example refrigerator compartments with a temperature range of \° to 15° C, freezer or deep-freeze compartments and/or cold storage compartments with temperatures of -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, the aim is to produce the combination devices in such a cost-effective and economical way that compartments with different temperatures are cooled by a common or connected evaporator or a connected cooling circuit. In addition, the devices should be able to be operated economically, i.e. 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 manufactured 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 wall, and with at least one door or flap closing this, in which a cooling fan is arranged in the upper region of the cooling compartment and a cooling air channel is separated by a partition wall approximately parallel to the rear wall of the cooling compartment, in which an evaporator is located and which opens into the cold storage compartment through openings in the rear region of the partition wall, in which openings and/or a gap between the partition wall and the door are provided in the front region of the partition wall, 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 flow cooling the refrigerator 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 exposed to colder air and is therefore cooled more than the refrigerator compartment into which the air exiting from the cold storage compartment enters.
Die Kühlleistung wird erfindungsgemäß durch folgende Parameter beeinflußt:According to the invention, the cooling performance is influenced by the following parameters:
1. Laufzeit des Kompressors1. Compressor running time
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.The cooling capacity provided by the evaporator depends on the running time of the compressor, which is taken from the cooling air flowing over the evaporator through the cooling air duct.
2. Einschaltdauer des Kühlgebläses2. Cooling fan operating time
Unter der Einschaltdauer ist die relative Laufzeit des Kühlgebläses zu verstehen, also das Verhältnis der Einschaltzeiten des Kühlgebläses zu den Ausschaltzeiten.The duty cycle refers to the relative running time of the cooling fan, i.e. the ratio of the cooling fan's on times to its off times.
3. Drehzahl des Kühlgebläses3. Cooling fan speed
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 speed of the cooling fan can influence the volume flow of the cooling air, whereby at high speeds a large cooling capacity is taken from the cooling air flow by the evaporator. Due to the high volume flow rate of the cooling air, however, it is cooled less than cooling air that passes over the evaporator with a reduced volume flow and can therefore reach 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 with one another in such a way that the desired temperatures prevail in both compartments, i.e. a temperature fluctuating by +1° C in the cold storage compartment and a temperature in the range of 4° to 9° C in the refrigerator compartment.
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 Ven-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 send signals corresponding to the measured temperatures to an electronic processing unit (microcomputer), which, based on appropriate control programs, controls the running time of the compressor, the relative duty cycle of the fan and the speed of the fan in order to maintain the desired temperatures.
tilators entsprechend steuert. Die Abstimmung dieser zu steuernden Parameter aufeinander kann empirisch oder aber auch rechnerisch erfolgen.tilators accordingly. The coordination of these parameters to be controlled can be done empirically or 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 must be adapted empirically or mathematically to the cooling requirements of the refrigerator 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 preferably arranged freely hanging in the cooling air duct. However, the evaporator can also be foamed in behind the rear wall of the cooling 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 in more detail below with reference to the drawing, in the only 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 partition walls 4, 5. The partition wall 4 separates an upper cooling compartment 6 from a lower cold storage compartment 7. A freezer compartment can also be arranged under the partition wall 5, but this is not part of the invention in the present case and is therefore not taken into account. The body part containing the cooling compartment 6 and the cold storage compartment 7 can be closed by a conventional door 8. An insulating partition wall 9 is arranged approximately parallel to the rear wall 2, which separates a cooling air channel 10 from the cooling compartment 6. The cooling air channel 10 widens in its lower area in the direction of the partition wall 4 due to the illustrated inclination of the lower part of the partition wall 9. In the rear area of the upper cover wall 3 a cooling fan 11 is arranged, the outlet opening or outlet gap 12 of which opens into the cooling air channel 10.
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 arranged freely suspended in the cooling air duct 10. At the lower end of the cooling air duct 10, a channel 14 is provided, which serves 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 area in the opening area 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 covered 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 flow emerging from the cold storage compartment then passes 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 subsequently 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.In the refrigerator compartment, shelves and a drawer can be arranged as 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 switching on times of the compressor and the cooling fan as well as for controlling the speed of the cooling fan is not shown. However, this can be set empirically or mathematically so that the cold storage compartment and the cooling compartment are flowed through by a flow of cooling air at a speed and at a temperature that 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 partition walls and the door must be selected so that the optimal temperature distribution is achieved with minimal cold loss.
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 gaps 15, 19 in the partition wall 4 must also be set according to the desired temperature distribution.
