Kühl- und/oder GefriergerätFridge and / or freezer
Die Erfindung betrifft ein Kühl- und/oder Gefriergerät mit einem Raum zur Aufnahme des Kühl- bzw. Gefriergutes, mit einem Ventilator, der Luft aus dem Raum abzieht oder in den Raum einbläst oder die in dem Raum befindliche Luft umwälzt, sowie mit einer mit dem Ventilator in Verbindung stehenden Steuereinheit.The invention relates to a refrigerator and / or freezer with a space for receiving the refrigerated or frozen, with a fan that extracts air from the room or blows into the room or circulating the air in the room, as well as with a the fan related control unit.
Die Ventilatoren derartiger Kühl- und/oder Gefriergeräte dienen je nach Ausführung des Gerätes unterschiedlichen Zwecken. Es sind Geräte bekannt, bei denen die Ventilatoren dazu eingesetzt werden, eine möglichst gleichmäßige Temperaturverteilung in dem Kühl- bzw. Gefrierraum herzustellen oder aufrecht zu erhalten. Des Weiteren sind Geräte bekannt, die mehrere Kompartimente aufweisen, die bei unterschiedlicher Temperatur betrieben werden, und bei denen der Ventilator dazu dient, diese Temperaturunterschiede aufrecht zu erhalten. Dies wird dadurch erreicht, dass durch einen Verdampfer gekühlte Luft mittels des Ventilators durch einen Kühlluftkanal zunächst in das Kaltlagerfach geführt wird und dieses auf eine niedrigere Temperatur kühlt als das Kühlfach, in das die Luft nach Durchströmen des Kaltlagerfaches einströmt. Aus dem Kühlfach wird die Luft mittels des Ventilators erneut in den Kühlluftkanal und von dort in das Kaltlagerfach geführt. Zur Steuerung des Betriebes des Ventilators ist eine Steuereinheit vorgesehen, die beispielsweise die Einschaltdauer des Ventilators steuert.The fans of such refrigerators and / or freezers serve different purposes depending on the design of the device. Devices are known in which the fans are used to produce or maintain the most uniform possible temperature distribution in the refrigerator or freezer compartment. Furthermore, devices are known which have several compartments which are operated at different temperatures, and in which the fan serves to maintain these temperature differences. This is achieved by the fact that air cooled by an evaporator by means of the fan through a cooling air duct is first conducted into the cold storage compartment and this cools to a lower temperature than the cooling compartment, in which the air flows in after flowing through the cold storage compartment. From the cooling compartment, the air is guided again by means of the fan into the cooling air duct and from there into the cold storage compartment. To control the operation of the fan, a control unit is provided which controls, for example, the duty cycle of the fan.
Ein Nachteil bei derartigen Kühl- und/oder Gefriergeräten besteht darin, dass je nach Betriebszustand gegebenenfalls ein Ausschaltwert erreicht wird, bevor die räumlichen Abkühlwerte erreicht sind. Das heißt, es kann der Fall eintreten, dass der Ventilator abgeschaltet wird, obwohl der Temperatur-Istwert eines Komparti- mentes nicht dem Temperatur-Sollwert entspricht oder in einem Temperatur- Sollwertbereich liegt.A disadvantage of such refrigerators and / or freezers is that, depending on the operating state, if necessary, a switch-off value is reached before the spatial cooling values are reached. This means that it can happen that the fan is switched off, even though the temperature actual value of a compartment does not correspond to the temperature setpoint or lies within a temperature setpoint range.
Es ist daher die Aufgabe der vorliegenden Erfindung, ein Kühl- und/oder Gefriergerät der eingangs genannten Art dahingehend weiterzubilden, dass die Einstellung von Temperaturwerten oder einer Temperaturverteilung verbessert wird.It is therefore the object of the present invention to develop a refrigerator and / or freezer of the type mentioned in such a way that the setting of temperature values or a temperature distribution is improved.
Diese Aufgabe wird durch ein Kühl- und/oder Gefriergerät mit den Merkmalen des Anspruchs 1 gelöst. Danach ist vorgesehen, dass die Steuereinheit den Ventilator zum Zwecke der Beeinflussung der Temperaturverteilung derart ansteuert, dass dieser in einem ersten Betriebszustand in einer Drehrichtung und in einem zweiten Betriebszustand in der anderen Drehrichtung betrieben wird. Die Ventilatordrehrichtung wird somit erfindungsgemäß umgedreht. Dadurch ist es möglich, kalte Luft direkt in die gewünschten Bereich einzublasen, sofern für diese ein Kühlluftbedarf besteht. Unter Drehrichtung des Ventilators wird die Drehrichtung beispielsweise eines Ventilatorrades bzw. die Förderrichtung eines beliebigen anderen Förderorgans verstanden.This object is achieved by a refrigerator and / or freezer with the features of claim 1. Thereafter, it is provided that the control unit controls the fan for the purpose of influencing the temperature distribution such that it is operated in a first operating state in one direction of rotation and in a second operating state in the other direction of rotation. The fan rotation direction is thus reversed according to the invention. This makes it possible to inject cold air directly into the desired area, if there is a need for cooling air. Under the direction of rotation of the fan, the direction of rotation, for example, a fan wheel or the conveying direction of any other conveying member understood.
Denkbar ist beispielsweise, dass die Umkehr der Drehrichtung des Ventilators für eine bestimmte Dauer oder in Abhängigkeit von Meßwerten, insbesondere von Temperaturmesswerten vorgenommen wird. Denkbar ist beispielsweise, dass bei einem Gerät mit einem Kühlfach und einem Kaltlagerfach der Ventilator in einer Drehrichtung betrieben wird, bei dem durch einen Verdampfer gekühlte Luft nicht in das Kaltlagerfach, sondern in das Kühlfach gefördert wird, sofern dessen Temperatur-Istwert oberhalb eines Grenzwertes liegt.It is conceivable, for example, that the reversal of the direction of rotation of the fan for a certain duration or in dependence on measured values, in particular of temperature measured values is made. It is conceivable, for example, that in a device with a cooling compartment and a cold storage compartment, the fan is operated in one direction of rotation, in which cooled by an evaporator air is not in the cold storage compartment, but is conveyed into the refrigerated compartment, provided that the actual temperature value is above a limit value.
Selbstverständlich ist auch eine davon abweichende Ventilatorsteuerung denkbar.Of course, a deviating fan control is conceivable.
In bevorzugter Ausgestaltung der Erfindung ist wenigstens ein Temperaturfühler zur Ermittlung eines Temperatur-Istwertes vorgesehen, wobei die Wahl des Betriebszustandes, d. h. die Wahl der Drehrichtung des Ventilators von dem Temperatur- Istwert, insbesondere von dem Temperatur-Istwert des Raumes abhängt, der zur Aufnahme des Kühl- bzw. Gefriergutes dient. Ein oder mehrere Temperatursensoren können auch an anderer Stelle des Gerätes angeordnet sein. Beispielsweise ist denkbar, dass ein Temperaturfühler am Verdampfer oder im Bereich des Verdampfers, ein Temperaturfühler im Kühlteil und ein Temperaturfühler im Kaltlagerfach oder in einem dem Kaltlagerfach vorgelagerten Bereich angeordnet ist.In a preferred embodiment of the invention, at least one temperature sensor is provided for determining a temperature actual value, wherein the choice of the operating state, d. H. the choice of the direction of rotation of the fan of the actual temperature value, in particular depends on the actual temperature value of the room, which serves to hold the refrigerated or frozen goods. One or more temperature sensors can also be arranged elsewhere in the device. For example, it is conceivable that a temperature sensor is arranged on the evaporator or in the region of the evaporator, a temperature sensor in the cooling part and a temperature sensor in the cold storage compartment or in a region upstream of the cold storage compartment.
Wie oben ausgeführt, kann der Raum in mehrer Kompartimente unterteilt sein, wobei in einem, mehreren oder allen Kompartimenten wenigstens ein Temperaturfühler angeordnet ist. Grundsätzlich ist denkbar, dass alle Kompartimente bei derselben Temperatur betrieben werden. Denkbar ist somit, dass alle Kompartimente des Gerätes beispielsweise als Kühlfächer oder als Kaltlagerfächer ausgeführt sind. Von der Erfindung umfasst ist ebenfalls eine Ausführungsform, bei der der gesamte Kühl- bzw. Gefrierraum nur ein einziges Kompartiment aufweist. Bevorzugt ist jedoch eine Ausgestaltung der Erfindung, bei der das Gerät zwei oder mehr als zwei Temperaturzonen aufweist, in denen im Betrieb des Gerätes unterschiedliche Temperaturen eingestellt werden.As stated above, the space can be subdivided into several compartments, wherein at least one temperature sensor is arranged in one, several or all compartments. In principle, it is conceivable that all compartments are operated at the same temperature. It is thus conceivable that all compartments of the device are designed, for example, as cooling compartments or cold storage compartments. Also included in the invention is an embodiment in which the entire refrigerator or freezer compartment has only a single compartment. However, an embodiment of the invention in which the device has two or more than two temperature zones, in which different temperatures are set during operation of the device, is preferred.
Dabei kann eine Temperaturzone durch ein oder mehrere Kühlfächer und eine weitere Temperaturzone durch ein oder mehrere Kaltlagerfächer gebildet werden. In bevorzugter Ausgestaltung der Erfindung befindet sich das oder die Kaltlagerfächer unterhalb des oder der Kühlfächer. Die Steuereinheit ist in weiterer Ausgestaltung der Erfindung derart ausgeführt, dass die Ansteuerung des Ventilators in Abhängigkeit von mehreren Temperatur-Istwerten, insbesondere von den Temperatur- Istwerten mehrerer Kompartimente erfolgt. Denkbar ist beispielsweise, dass sowohl in dem Kühlfach als auch in dem Kaltlagerfach jeweils ein Temperaturfühler vorgesehen ist und dass die Drehrichtung des Ventilators in Abhängigkeit beider Temperatur-Istwerte gewählt wird.In this case, a temperature zone can be formed by one or more cooling compartments and a further temperature zone by one or more cold storage compartments. In a preferred embodiment of the invention, the one or more cold storage compartments below the or the cooling compartments. The control unit is designed in a further embodiment of the invention such that the control of the fan in response to a plurality of actual temperature values, in particular of the temperature Actual values of several compartments. It is conceivable, for example, that a temperature sensor is provided both in the cooling compartment and in the cold storage compartment and that the direction of rotation of the fan is selected as a function of both actual temperature values.
Die Steuereinheit kann derart ausgeführt sein, dass die Drehrichtung bei Überschreiten und/oder Unterschreiten eines Temperatur-Sollwertes oder bei Verlassen und/oder Erreichen eines Temperatur-Sollwertbereiches geändert wird. Befinden sich die Temperatur-Istwerte in einem gewünschten Bereich, kann vorgesehen sein, dass die Steuereinheit den Ventilator abschaltet.The control unit may be designed such that the direction of rotation is changed when exceeding and / or falling below a temperature setpoint or when leaving and / or reaching a temperature setpoint range. If the actual temperature values are in a desired range, it can be provided that the control unit switches off the fan.
Die Erfindung betrifft ferner ein Verfahren zum Betreiben eines Kühl- und/oder Gefriergerätes mit einem Raum zur Aufnahme des Kühl- bzw. Gefriergutes, mit einem Ventilator, der Luft aus dem Raum abzieht oder in den Raum einbläst oder die in dem Raum befindliche Luft umwälzt, wobei der Ventilator zum Zwecke der Beeinflussung der Temperaturverteilung mit unterschiedlichen Drehrichtungen betrieben wird.The invention further relates to a method for operating a refrigerator and / or freezer with a space for receiving the goods to be refrigerated or frozen, with a fan that draws air from the room or blows into the room or circulating the air in the room , wherein the fan is operated for the purpose of influencing the temperature distribution with different directions of rotation.
Dabei ist es möglich, dass der Ventilator für eine bestimmte Dauer in der einen oder anderen Drehrichtung betrieben wird oder dass die Wahl der Drehrichtung von einem Meßwert, insbesondere von dem wenigstens einen Temperaturmesswert abhängt. In bevorzugter Ausgestaltung der Erfindung ist vorgesehen, dass die Drehrichtung von dem Temperatur-Istwert des Raumes abhängt, der zur Aufnahme von Kühl- bzw. Gefriergut dient.It is possible that the fan is operated for a certain duration in one or the other direction of rotation or that the choice of the direction of rotation of a measured value, in particular depends on the at least one temperature reading. In a preferred embodiment of the invention, it is provided that the direction of rotation depends on the temperature actual value of the room, which serves to hold refrigerated or frozen goods.
Wie oben ausgeführt, ist die vorliegende Erfindung besonders vorteilhaft bei Geräten einsetzbar, die mehrere Kompartimente aufweisen. Dabei kann vorgesehen sein, dass die Wahl der Drehrichtung des Ventilators von dem Temperatur-Istwert eines, mehrerer oder aller Kompartimente abhängt. Besonders vorteilhaft ist es, wenn das Gerät wenigstens ein Kühlfach und wenigstens ein Kaltlagerfach aufweist und wenn die Drehrichtung des Ventilators von dem in dem Kühlfach und/oder Kaltlagerfach gemessenen Temperatur-Istwert abhängt. In bevorzugter Ausgestaltung der Erfindung ist die Steuereinheit programmierbar, so dass flexibel vorgegeben werden kann, beim Erreichen welcher Zustände des Gerätes der Ventilator auszuschalten, in dem ersten Betriebszustand oder in dem zweiten Betriebszustand zu betreiben ist. Zusätzlich kann vorgesehen sein, dass die Steuereinheit nicht nur die Drehrichtung des Ventilators, sondern auch dessen Drehzahl in Abhängigkeit von Meßwerten bzw. der erforderlichen Kühlleistung steuert.As stated above, the present invention is particularly advantageous for devices having multiple compartments. It can be provided that the choice of the direction of rotation of the fan of the temperature actual value of one, several or all compartments depends. It is particularly advantageous if the device has at least one cooling compartment and at least one cold storage compartment and if the direction of rotation of the fan depends on the actual temperature value measured in the cooling compartment and / or cold storage compartment. In a preferred embodiment of the invention, the control unit is programmable, so that it can be flexibly specified, when reaching which states of the device to turn off the fan, to operate in the first operating state or in the second operating state. In addition, it can be provided that the control unit controls not only the direction of rotation of the fan, but also its speed as a function of measured values or the required cooling capacity.
Die Ansteuerung des Ventilators durch die Steuereinheit in Abhängigkeit von gemessenen Parametern kann in unterschiedlicher Art und Weise erfolgen. Denkbar ist beispielsweise, dass die Drehrichtung des Ventilators derart eingestellt wird, dass die Luft von dem Verdampfer in das Kaltlagerfach gefördert wird, wenn die Kaltlagerfachtemperatur einen Grenzwert übersteigt und dass die Luft von dem Verdampfer in das Kühlfach gefördert wird, wenn die Kühlfachtemperatur einen Grenzwert übersteigt. Des Weiteren kann vorgesehen sein, dass für den Fall, dass sowohl die Kaltlagerfachtemperatur als auch die Kühlfachtemperatur Grenzwerte übersteigen, die Drehrichtung des Ventilators zunächst derart eingestellt wird, dass die Luft von dem Verdampfer in das Kaltlagerfach oder in das Kühlfach gefördert wird und dass nach Erreichen des Sollwertes oder eines Sollwertbereiches der Temperatur dieses Faches die Drehrichtung des Ventilators umgekehrt wird, so dass die Kaltluft unmittelbar in das andere der Fächer gefördert wird.The control of the fan by the control unit in dependence on measured parameters can be done in different ways. It is conceivable, for example, that the direction of rotation of the fan is adjusted so that the air is conveyed from the evaporator into the cold storage compartment when the cold storage compartment temperature exceeds a limit and that the air is conveyed from the evaporator into the refrigerating compartment when the refrigeration compartment temperature exceeds a limit , Furthermore, it can be provided that in the event that both the cold storage compartment temperature and the refrigeration compartment temperature exceed limits, the direction of rotation of the fan is initially set such that the air is conveyed by the evaporator in the cold storage compartment or in the cooling compartment and that after reaching the setpoint or a setpoint range of the temperature of this compartment, the direction of rotation of the fan is reversed, so that the cold air is conveyed directly into the other of the compartments.
Weitere Einzelheiten und Vorteile der Erfindung werden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die einzige Figur zeigt eine Schnittdarstellung eines Kühlgerätes mit zwei Temperaturzonen.Further details and advantages of the invention will be explained in more detail with reference to an embodiment shown in the drawing. The single FIGURE shows a sectional view of a refrigerator with two temperature zones.
Das Kühlgerät weist einen den Raum 10 begrenzenden Innenbehälter auf, dessen Frontseite durch eine Tür 11 verschließbar ist. Der Raum 10 ist in das Kühlfach 12 sowie die beiden Kaltlagerfächer 14, 16 unterteilt. Wie dies aus der Figur ersichtlich ist, befindet sich das Kühlfach 12 in dem oberen Bereich des Gerätes und darunter, unterhalb der horizontalen Trennplatte 70 das obere Kaltlagerfach 14 und darunter unterhalb eines Zwischenbodens das zweite Kaltlagerfach 16.The refrigerator has a space 10 limiting inner container, the front side is closed by a door 11. The space 10 is divided into the cooling compartment 12 and the two cold storage compartments 14, 16. As can be seen from the figure, the refrigerating compartment 12 is located in the upper area of the appliance and below, Below the horizontal partition plate 70, the upper cold storage compartment 14 and below underneath an intermediate floor, the second cold storage compartment 16th
In dem Kühlteil 12 liegt eine gemittelte Temperatur im Bereich von 2 °C bis 9 0C vor; in dem Kaltlagerfach 14 liegt eine Temperatur im Bereich zwischen 0 °C und 3 0C und in dem Kaltlagerfach 16 eine Temperatur im Bereich zwischen 0 0C und 3 0C vor.In the cooling part 12 is an average temperature in the range of 2 ° C to 9 0 C before; in the cold storage compartment 14 is a temperature in the range between 0 ° C and 3 0 C and in the cold storage compartment 16 is a temperature in the range between 0 0 C and 3 0 C.
Wie oben ausgeführt, ist das Kühlfach 12 unten durch die horizontale Trennplatte 70 begrenzt. Die rückwärtige Begrenzung des Kühlfaches 12 wird durch die vertikale Trennplatte 60 gebildet. Beide Trennplatten 60, 70 sind wärmeisoliert ausgeführt.As stated above, the cooling compartment 12 is bounded below by the horizontal partition plate 70. The rear boundary of the refrigerating compartment 12 is formed by the vertical partition plate 60. Both partition plates 60, 70 are designed heat-insulated.
In ihrem oberen Endbereich weist die vertikale Trennplatte 60 eine Ausnehmung auf, in der der Ventilator 20 angeordnet ist. In dem Bereich zwischen der vertikalen Trennplatte 60 und der Rückwand des Gerätes befindet sich der Kühlluftkanal 120, in dem freihängend der Verdampfer 50 angeordnet ist. Der Verdampfer 50 ist an der Rückwand des Gerätes befestigt.In its upper end region, the vertical partition plate 60 has a recess in which the fan 20 is arranged. In the area between the vertical partition plate 60 and the rear wall of the device is the cooling air passage 120, in which the evaporator 50 is arranged freely suspended. The evaporator 50 is attached to the rear wall of the device.
Das Gerät weist ferner als Bestandteile des Kühlkreislaufes den Kompressor 90 sowie den Verflüssiger 80 auf der Außenseite der Rückwand des Gerätes auf.The device also has as components of the cooling circuit the compressor 90 and the condenser 80 on the outside of the rear wall of the device.
In dem Kühlfach 12 befinden sich Böden zur Aufnahme des Kühlgutes. Ein Boden ist des Weiteren zwischen den Kaltlagerfächern 14, 16 angeordnet, in denen sich beispielsweise Schubladen befinden. Wie dies aus der Figur ersichtlich ist, ist eine weitere Schublade im Kühlfach 12 angeordnet.In the cooling compartment 12 are floors for receiving the refrigerated goods. A floor is further arranged between the cold storage compartments 14, 16, in which, for example, drawers are located. As can be seen from the figure, another drawer is arranged in the refrigerating compartment 12.
Die Bezugszeichen 30, 32, 34 kennzeichnen Temperaturfühler, wobei der Temperaturfühler 30 am Verdampfer 50, der Temperaturfühler 32 im Übergangsbereich zwischen Kühlluftkanal 120 und den Kaltlagerfächern 14, 16 und der Temperaturfühler 34 im Kühlfach 12 angeordnet ist.Reference numerals 30, 32, 34 designate temperature sensors, wherein the temperature sensor 30 is arranged on the evaporator 50, the temperature sensor 32 in the transition region between the cooling air duct 120 and the cold storage compartments 14, 16 and the temperature sensor 34 in the refrigeration compartment 12.
Das Bezugszeichen 40 kennzeichnet die Steuereinheit bzw. die Steuerelektronik. Wie oben ausgeführt, weist das Gerät somit zwei Temperaturzonen auf, von denen die eine durch das Kühlfach 12 und die andere durch die Kaltlagerfächer 14, 16 gebildet wird. In dem durch Pfeile symbolisierten Betriebszustand wird der Ventilator derart betrieben, dass er Luft aus dem Kühlfach 12 in den Kühlluftkanal 120 fördert. In diesem wird die Kühlluft durch den Verdampfer 50 gekühlt und tritt sodann in die Kaltlagerfächer 14, 16 ein.The reference numeral 40 denotes the control unit or the control electronics. As stated above, the device thus has two temperature zones, one of which is formed by the cooling compartment 12 and the other by the cold storage compartments 14, 16. In the operating state symbolized by arrows, the fan is operated such that it conveys air from the cooling compartment 12 into the cooling air channel 120. In this, the cooling air is cooled by the evaporator 50 and then enters the cold storage compartments 14, 16 a.
Durch einen Spalt zwischen der zur Bedienseite gerichteten Frontseite der horizontalen Trennplatte 70 und der Tür 11 tritt die Luft aus den Kaltlagerfächern 14, 16 in das Kühlfach 12 ein und wird von dort mittels des Ventilators 20 wieder in den Kühlluftkanal 120 geführt. Somit ergibt sich ein Kühlluftkreislauf, bei dem die kalte Luft zunächst in die Kaltlagerfächer 14, 16 und sodann von diesen in das Kühlfach 12 geführt wird.Through a gap between the side facing the operating side of the horizontal partition plate 70 and the door 11, the air from the cold storage compartments 14, 16 enters the refrigerating compartment 12 and is guided from there by means of the fan 20 back into the cooling air passage 120. This results in a cooling air circuit in which the cold air is first fed into the cold storage compartments 14, 16 and then from these into the refrigerating compartment 12.
Um zu vermeiden, dass ein Ausschaltwert für den Ventilator 20 erreicht wird, bevor die räumlichen Abkühlwerte erreicht sind, ist erfindungsgemäß vorgesehen, dass die Steuereinheit 40 den Ventilator 20 auch in der Gegenrichtung betreiben kann. In dieser wird dementsprechend kalte Luft aus dem Kühlluftkanal 120 zunächst in das Kühlfach 12 geführt und Luft aus den Kaltlagerfächern 14, 16 abgeführt. Die Luftbewegung erfolgt in diesem Fall in einer der dargestellten entgegengesetzten Richtung. Aufgrund der Tatsache, dass die Ventilatordrehrichtung bei Bedarf umgedreht werden kann, ist es möglich, kalte Luft direkt in die gewünschten Bereiche einzu- blasen und gegebenenfalls die Laufzeit des Kompressors 90 zu verlängern.In order to avoid that a switch-off value for the fan 20 is reached before the spatial Abkühlwerte are reached, the invention provides that the control unit 40, the fan 20 can also operate in the opposite direction. Accordingly, cold air from the cooling air duct 120 is first led into the cooling compartment 12 and air is removed from the cold storage compartments 14, 16. The air movement is in this case in one of the illustrated opposite direction. Due to the fact that the fan rotation direction can be reversed if necessary, it is possible to blow cold air directly into the desired areas and possibly to extend the running time of the compressor 90.
In einem Ausführungsbeispiel ist denkbar, dass der Ventilator 20 zum Zwecke der Kühlung des Raumes 10 zunächst in der in der Figur dargestellten Richtung betrieben wird. Dementsprechend strömt die Luft durch den Kühlluftkanal 120 zunächst in die Kaltlagerfächer 14, 16. Nach der Durchströmung und Kühlung dieser Fächer tritt die Luft sodann durch den zwischen der horizontalen Trennplatte 70 und der Tür 11 befindlichen Spalt in das Kühlfach 12 ein. Meldet der Temperaturluftfühler 32, dass die Kaltlagerfachtemperatur einem gewünschten Wert entspricht und mel- det der Temperaturfühler 34, dass die Temperatur in dem Kühlteil 12 oberhalb eines Grenzwertes liegt, kann die Steuereinheit 40 die Drehrichtung des Ventilators für eine bestimmte Dauer oder so lange umkehren, bis auch in dem Kühlfach 12 der gewünschte Temperaturwert erreicht ist.In one embodiment, it is conceivable that the fan 20 is first operated in the direction shown in the figure for the purpose of cooling the space 10. Accordingly, the air flows through the cooling air passage 120 first in the cold storage compartments 14, 16. After the flow and cooling of these compartments, the air then enters through the located between the horizontal partition plate 70 and the door 11 gap in the refrigerating compartment 12 a. If the temperature air sensor 32 notifies that the cold storage compartment temperature corresponds to a desired value and reports If the temperature sensor 34 determines that the temperature in the cooling part 12 is above a limit value, the control unit 40 can reverse the direction of rotation of the fan for a certain duration or until the desired temperature value has been reached in the cooling compartment 12.
Erfindungsgemäß ist es möglich, kalte Luft direkt in die gewünschten Bereiche ein- zublasen und damit zu verhindern, dass ein Ausschaltwert erreicht wird, bevor die räumlichen Abkühlwerte erreicht sind. According to the invention, it is possible to blow cold air directly into the desired areas and thus to prevent a switch-off value being reached before the spatial cooling values have been reached.
