Description

Die vorliegende Erfindung betrifft ein Kühlgerät, insbesondere ein Haushaltskältegerät das besonders zum Kühlen von Lebensmitteln geeignet ist, deren Qualität kritisch von den klimatischen Bedingungen ihrer Lagerung abhängt, wie insbesondere Wein. Die langfristige Lagerung von Weinen findet üblicherweise in Kellern statt, deren Temperatur im allgemeinen von der optimalen Trinktemperatur der Weine verschieden ist. Bei vielen Weißweinen und Sekt ist die optimale Trinktemperatur meist niedriger als die Kellertemperatur, während sie bei Rotweinen höher sein kann. Um die Weine auf Trinktemperatur zu bringen, werden diese häufig zum Abkühlen in einen Kühlschrank gesteckt, wo sie abrupt auf dessen Innentemperatur heruntergekühlt werden, oder sie werden in einen bewohnten Raum gebracht, wo sie sich auf dessen Temperatur erwärmen können. Derartige abrupte Temperaturänderungen sind genau das, was man bei der langfristigen Lagerung der Weine in Kellern zu vermeiden versucht, und sie können deren Qualität negativ beeinflussen.The present invention relates to a refrigerator, in particular a household refrigeration appliance which is particularly suitable for cooling food, the quality of which critically depends on the climatic conditions of their storage, in particular wine. The long-term storage of wines usually takes place in cellars whose temperature is generally different from the optimum drinking temperature of the wines. For many white wines and sparkling wines, the optimum drinking temperature is usually lower than the cellar temperature, while it may be higher for red wines. To bring the wines to drinking temperature, they are often placed in a refrigerator for cooling, where they are abruptly cooled down to its internal temperature, or they are brought to an inhabited room where they can be heated to its temperature. Such abrupt temperature changes are exactly what you try to avoid in the long-term storage of wines in cellars, and they can negatively affect their quality.

Aus DE 101 45 146 A1 ist ein Kühlgerät bekannt, das in der Lage ist, in einem gesteuerten Temperierprozess Wein behutsam auf eine gewünschte Trinktemperatur zu bringen. Der Temperierprozess setzt ein bei einer von einem Temperatursensor im Lagerfach erfassten Temperatur, die als Anfangs-Temperatursollwert genommen wird. Ausgehend von diesem Anfangswert nähert sich der Temperatursollwert im Laufe des Temperaturprozesses schrittweise der Trinktemperatur.Out DE 101 45 146 A1 is a cooling device is known, which is able to gently bring in a controlled tempering wine to a desired drinking temperature. The tempering process starts at a temperature detected by a temperature sensor in the storage compartment, which is taken as the initial temperature setpoint. Starting from this initial value, the temperature set point gradually approaches the serving temperature during the temperature process.

Zwar stellt bereits dieser herkömmliche Temperierprozess einen erheblichen Fortschritt gegenüber dem einfachen Abkühlen im Kühlschrank oder Aufwärmen im Zimmer dar, doch sind die Ergebnisse nicht immer absolut befriedigend. Ein Grund dafür hängt mit der Variabilität der Temperatur im Lagerfach des Kühlgeräts zusammen. Wenn ein Temperierprozess abgeschlossen und die temperierten Flaschen aus dem Gerät ausgeladen worden sind, befindet sich das Lagerfach im Allgemeinen nicht auf einer für den Start des nächsten Temperierprozesses geeigneten Temperatur. Auch wenn das Gerät vor dem Start eines Temperierprozesses ausgeschaltet gewesen ist, hat sein Lagerfach im Allgemeinen nicht die richtige Temperatur. Wenn es in diesem Zustand mit kellerkalten Flaschen beladen wird, ist die Lagerfachtemperatur mit Abschluss der Beladung im Allgemeinen deutlich höher als die Kellertemperatur. Daraus resultiert eine zu hohe Anfangs-Solltemperatur, so dass im Falle des Warmtemperierens die Flaschen anfangs unerwünscht schnell erwärmt werden und im Falle des Kalttemperierens der Temperierprozess unnötig viel Zeit in Anspruch nimmt und eventuell sogar die Flaschen zunächst erwärmt, bevor er sie kühlt.Although this conventional tempering process represents a significant advance over simply cooling in the refrigerator or warming up in the room, the results are not always completely satisfactory. One reason for this is related to the variability of the temperature in the storage compartment of the refrigerator. When a tempering process has been completed and the tempered bottles have been unloaded from the device, the storage compartment is generally not at a temperature suitable for the start of the next tempering process. Even if the device was switched off before starting a tempering process, its storage compartment generally does not have the correct temperature. When loaded with cold-cold bottles in this condition, the storage compartment temperature is at the end of the shelf life Loading generally significantly higher than the cellar temperature. This results in a too high initial target temperature, so that in the case of warm tempering the bottles are initially heated undesirably fast and takes in the case of cold tempering the tempering unnecessarily much time and possibly even the bottles first heated before he cools them.

Aufgabe der vorliegenden Erfindung ist daher, ein Kühlgerät zu schaffen, das auch unter den oben beschriebenen problematischen Bedingungen in der Lage ist, einen gleichmäßigen, behutsamen Temperierprozess durchzuführen.It is therefore an object of the present invention to provide a cooling device which is capable, even under the problematic conditions described above, of carrying out a uniform, gentle tempering process.

Die Aufgabe wird gelöst, indem bei einem Kühlgerät mit einem wenigstens ein Lagerfach umschließenden Gehäuse, einer Kältemaschine zum Kühlen des Lagerfachs und einem Steuerteil zum Steuern des Betriebs der Kältemaschine entsprechend einer Solltemperatur und zum zeitabhängigen Festlegen der Solltemperatur für einen Temperierprozess mit einer vorgegebenen Änderungsrate eine Start-Solltemperatur für den Temperierprozess an dem Steuerteil einstellbar ist. Indem diese Start-Solltemperatur entsprechend der Kellertemperatur eingestellt wird, kann sichergestellt werden, dass der Flascheninhalt in einem Temperierprozess gleichmäßig und langsam erwärmt oder abgekühlt wird, unabhängig von einer eventuellen Diskrepanz zwischen der Temperatur des Lagerfachs und der der Flaschen zu Beginn des Temperierprozesses.The object is achieved by starting at a cooling device with a housing enclosing at least one storage compartment, a refrigerator for cooling the storage compartment and a control unit for controlling the operation of the refrigerator according to a setpoint temperature and time-dependent setting of the setpoint temperature for a tempering process with a predetermined rate of change -Solltemperatur for the tempering process on the control part is adjustable. By setting this start temperature setpoint according to the cellar temperature, it is possible to ensure that the contents of the cylinder are uniformly and slowly heated or cooled in a tempering process, regardless of any discrepancy between the temperature of the storage compartment and that of the bottles at the beginning of the tempering process.

Zweckmäßigerweise sind an dem Steuerteil auch die End-Solltemperatur und/oder eine Änderungsrate der Solltemperatur einstellbar.Expediently, the end setpoint temperature and / or a rate of change of the setpoint temperature can also be set on the control part.

Während des Temperierprozess, insbesondere in einer Anfangsphase desselben kann es durchaus zweckmäßig sein, die Solltemperatur an eine in dem Lagerfach gemessene Temperatur anzugleichen. Auf diese Weise kann einer eventuellen Abweichung zwischen der Anfangstemperatur der Flaschen und der eingestellten Start-Solltemperatur Rechnung getragen werden.During the tempering process, in particular in an initial phase of the same, it may well be appropriate to adjust the target temperature to a temperature measured in the storage compartment. In this way, a possible deviation between the initial temperature of the bottles and the set start temperature setpoint can be taken into account.

Um eine gleichmäßige Temperaturverteilung zu erzielen, ist das Lagerfach zweckmäßigerweise mit einem Ventilator ausgestattet. Vorzugsweise ist der Ventilator zwischen dem Lagerfach und einer Verdampferkammer angeordnet. Dadurch kann die Temperatur der die Flaschen umspülenden Luft in der Lagerkammer in kurzer Zeit, im Allgemeinen bereits innerhalb weniger Minuten nach Beginn des Temperierprozesses, auf die Solltemperatur des Lagerfachs gebracht werden, auch wenn das das Lagerfach umschließende Gehäuse von dieser Solltemperatur noch weit entfernt ist. So können unerwünschte Temperatursprünge des Flascheninhalts zu Beginn des Temperierprozesses wirksam verhindert werden.In order to achieve a uniform temperature distribution, the storage compartment is expediently equipped with a fan. Preferably, the fan between the storage compartment and an evaporator chamber is arranged. As a result, the temperature of the air flowing around the bottles in the storage chamber in a short time, in the Generally within a few minutes after the beginning of the tempering process, be brought to the target temperature of the storage compartment, even if the housing enclosing the storage compartment of this target temperature is still far away. Thus, unwanted temperature jumps of the bottle contents can be effectively prevented at the beginning of the tempering process.

Zweckmäßigerweise ist das Steuerglied auch eingerichtet, einen Endzeitpunkt oder eine Restdauer des Temperierprozesses abzuschätzen und an einer Benutzerschnittstelle anzuzeigen. Dies ist besonders im Falle einer Korrektur der Solltemperatur anhand einer gemessenen Temperatur zweckmäßig, da in einem solchen Fall der Benutzer die Dauer des Temperierprozesses nicht selbst abschätzen kann.Expediently, the control element is also set up to estimate an end time or a remaining duration of the tempering process and display it on a user interface. This is particularly useful in the case of a correction of the setpoint temperature based on a measured temperature, since in such a case the user can not estimate the duration of the tempering process itself.

Zum Warmtemperieren ist es zweckmäßig, wenn dem Lagerfach auch eine Heizung zugeordnet ist und das Steuerteil eingerichtet ist, die Heizung entsprechend der Solltemperatur zu steuern.For warm temperature, it is expedient if the storage compartment is also assigned a heater and the control part is arranged to control the heating according to the target temperature.

Das Steuerteil kann zweckmäßigerweise einen Temperierbereitschaftszustand aufweisen, in welchem es das Lagerfach konstant auf der Start-Solltemperatur hält und bei Erfassung einer Türbetätigung einen Temperierprozess startet. Dies ermöglicht es dem Benutzer, das Lagerfach vor Beginn des Temperierprozesses auf die korrekte Starttemperatur zu bringen und auf unbestimmte Zeit auf dieser zu halten. Wenn eine Türbetätigung darauf schließen lässt, dass das Lagerfach beladen worden ist, startet der Temperierprozess automatisch. Dies ist insbesondere dann sinnvoll, wenn nur kleine Mengen an Flaschen eingeladen werden, deren Wärmekapazität gering ist. Wenn das Lagerfach voll geladen wird, ist die Wärmekapazität der eingeladenen Flaschen im Vergleich zur Wärmekapazität der Luft in dem Fach so groß, dass die Temperatur des Fachs vor Beginn des Temperierprozesses auf dessen Ablauf kaum merklichen Einfluss hat.The control part can expediently have a tempering standby state in which it keeps the storage compartment constant at the start setpoint temperature and starts a tempering process when a door operation is detected. This allows the user to bring the storage compartment before the tempering process to the correct starting temperature and to hold indefinitely on this. If a door operation indicates that the storage compartment has been loaded, the tempering process starts automatically. This is particularly useful when only small quantities of bottles are invited whose heat capacity is low. When the storage compartment is fully loaded, the heat capacity of the loaded bottles is so large compared to the heat capacity of the air in the compartment that the temperature of the compartment before the start of the tempering process has hardly noticeable influence.

The space between two adjacent bottoms 8, 9 is sized to store bottles lying therein; the distance between two adjacent bottoms 9 of great depth is chosen so that 9 bottles can be placed standing in a front edge region of each floor. Illuminants may be placed in the frame 4 or outside the doors to illuminate the standing bottles. Thus, for example, when the device is placed in a dining room, the wines offered for consumption can be presented in a conspicuous and inviting manner.

Während sich die Tür 1 über im Wesentlichen die gesamte Höhe des Geräts erstreckt, nehmen die Türen 2, 3 jeweils knapp die Hälfte der Höhe ein, und ein Bedienfeld 10, an dem die Funktionen des Geräts einstellbar sind, ist zwischen den Türen 2, 3 vorgesehen.While the door 1 extends over substantially the entire height of the appliance, the doors 2, 3 each occupy almost half the height, and a control panel 10, on which the functions of the appliance are adjustable, is between the doors 2, 3 intended.

Wie Fig. 2 zeigt, ist das Bedienfeld 10 über einen Bus 11 mit einem Mikrocontroller 12 verbunden, um Benutzerbefehle durch Betätigung von Tasten des Bedienfeldes 10 zu empfangen und Meldungen des Mikrocontrollers 12 auf einem Anzeigeschirm des Bedienfeldes 10 auszugeben. Der Mikrocontroller 12 kommuniziert mit Temperatursensoren 13, 14 in jedem der Lagerfächer 5, 6, 7, mit einem oder mehreren Verdichtern 16, gegebenenfalls mit nicht dargestellten Magnetventilen zum Verteilen von verdichtetem Kältemittel auf Verdampfer 15 der Lagerfächer, sowie mit einen Ventilator 17 und einer Heizung 18 in jedem Lagerfach.As Fig. 2 shows, the control panel 10 is connected via a bus 11 to a microcontroller 12 to receive user commands by operating keys of the control panel 10 and output messages of the microcontroller 12 on a display screen of the control panel 10. The microcontroller 12 communicates with temperature sensors 13, 14 in each of the storage compartments 5, 6, 7, with one or more compressors 16, optionally with non-illustrated solenoid valves for distributing compressed refrigerant on evaporator 15 of the storage compartments, and with a fan 17 and a heater 18 in each storage compartment.

Die mehreren Temperatursensoren, Verdichter und/oder Magnetventile ermöglichen eine Regelung der Temperatur in jedem der Fächer 5, 6, 7 unabhängig von den anderen. So kann z.B. in einem der Fächer ein Temperierprozess ablaufen, während ein anderes auf Flaschen auf Trinktemperatur enthält und das dritte ausgeschaltet ist, oder es können verschiedene Weinsorten in den einzelnen Fächern auf ihrer individuell verschiedenen optimalen Trinktemperatur gehalten werden.The plurality of temperature sensors, compressors and / or solenoid valves allow for control of the temperature in each of the compartments 5, 6, 7 independently of the others. Thus, e.g. in one of the compartments a tempering process takes place while another contains bottles at serving temperature and the third is off, or different types of wine in the individual compartments can be kept at their individually different optimum serving temperature.

Fig. 3 zeigt das Erscheinungsbild des Bedienfeldes 10 in einem stationären Betriebszustand. Den Lagerfächern 5, 6, 7 zugeordnete Anzeigefelder sind auf dem Anzeigeschirm 22 Anzeigefelder 19, 20, 21 zugeordnet, deren Anordnung die Anordnung der Fächer 5, 6, 7 am Gerät nachbildet und auf denen die jeweils vom Sensor 13 eines jeden Fachs gemessene Temperatur angezeigt ist. Alle drei Fächer sind hier konstant auf einer Solltemperatur von +12 Grad Celsius gehalten. Fig. 3 shows the appearance of the control panel 10 in a steady state operation. The storage compartments 5, 6, 7 associated display fields are assigned to the display screen 22 display panels 19, 20, 21, whose arrangement simulates the arrangement of the compartments 5, 6, 7 on the device and displayed on each of which measured by the sensor 13 of each compartment temperature is. All three compartments are kept constant at a target temperature of +12 degrees Celsius.

Den Anzeigeschirm 22 des Bedienfeldes 10 flankierenden Tasten 23 bis 28 sind Funktionen zur Steuerung des Gerätes zugewiesen, die durch jeweils benachbart zu ihnen auf dem Anzeigeschirm 22 angezeigte Symbole verdeutlicht sind. Im Rahmen der vorliegenden Erfindung interessiert von den in Fig. 3 angezeigten Symbolen im Wesentlichen nur das Symbol 29 neben der Taste 26, das für den Übergang in einen Programmiermodus steht. Durch Betätigen der Taste 26 sind der Reihe nach die einzelnen Fächer 6, 7, 8 zum Programmieren anwählbar, wobei die Programmierbereitschaft durch Invertierung des dem ausgewählten Fach entsprechenden Anzeigefeldes, in Fig. 4 des Anzeigefelds 19 des Fachs 6, angezeigt wird.The display screen 22 of the control panel 10 flanking keys 23 to 28 are assigned functions for controlling the device, which are illustrated by each adjacent to them on the display screen 22 displayed symbols. Within the scope of the present invention, interested in the in Fig. 3 Symbols displayed are essentially only the symbol 29 next to the key 26, which stands for the transition to a programming mode. By pressing the button 26 in turn, the individual compartments 6, 7, 8 are selected for programming, the programming readiness by inverting the selected tray corresponding display field, in Fig. 4 of the display panel 19 of the tray 6 is displayed.

Im Programmierbereitschaftsmodus der Fig. 4 bleibt das Symbol 29 erhalten, so dass über die Taste 26 ein anderes Fach ausgewählt werden kann. Minus- und Pluszeichen neben den Tasten 24, 27 machen deutlich, dass mit Hilfe dieser Tasten der Temperatursollwert des ausgewählten Fachs 6 dekrementiert bzw. inkrementiert werden kann.In programming standby mode the Fig. 4 the symbol 29 remains, so that via the key 26 another compartment can be selected. Minus and plus signs next to the keys 24, 27 make it clear that with the aid of these keys the temperature setpoint of the selected compartment 6 can be decremented or incremented.

Die Betätigung der Taste 23 bewirkt im in Fig. 4 gezeigten Zustand den Übergang in einen Temperier-Programmiermodus, dargestellt in Fig. 5. Ein Symbol 30 oben links in einem invertiert dargestellten zentralen Bereich des Anzeigeschirms 22 identifiziert das ausgewählte Lagerfach, hier das Fach 6. Eine in dem zentralen Bereich angezeigte Grafik 31 veranschaulicht den zeitlichen Ablauf des Temperierprozesses mit Start- und Endtemperaturen, hier 12 Grad Celsius und 17 Grad Celsius, und mit zwischen diesen beiden Werten linear mit der Zeit ansteigenden Solltemperaturen. Wie wiederum durch benachbarte Minus- und Pluszeichen verdeutlicht, dienen die Tasten 23, 24 zum Dekrementieren und Inkrementieren der Starttemperatur und die Tasten 26, 27 zum Inkrementieren und Dekrementieren der Endtemperatur. Die Anstiegsrate der Temperatur während des Temperiervorgangs von zum Beispiel 1 Grad Celsius pro Stunde ist hier fest vorgegeben, sie könnte auch dem Benutzer zur Programmierung freigestellt sein.The actuation of the button 23 causes in in Fig. 4 shown state the transition to a tempering programming mode, shown in Fig. 5 , A symbol 30 at the top left in an inverted central area of the display screen 22 identifies the selected storage compartment, here tray 6. A graphic 31 displayed in the central area illustrates the timing of the tempering process with start and end temperatures, here 12 degrees Celsius and 17 Degrees Celsius, and with these values rising linearly with time. As indicated again by adjacent minus and plus signs, the keys 23, 24 serve to decrement and increment the start temperature and the keys 26, 27 to increment and decrement the final temperature. The rate of increase of the temperature during the tempering of, for example, 1 degree Celsius per hour is fixed here, it could also be the user for programming exempted.

Das Anzeigebild der Fig. 5 kann über die Taste 28 verlassen werden, ohne einen Temperiervorgang zu starten, wie das benachbarte durchgestrichene Thermometersymbol verdeutlicht. Durch Betätigung der Taste 25 wird gleichzeitig mit dem Verlassen des Anzeigebildes ein Temperiervorgang gestartet. Der Benutzer gelangt in diesem Fall zum Anzeigebild der Fig. 6, in dem die für den Temperierprozess eingestellten Parameter im Anzeigefeld 19 des Fachs 6 zu sehen sind, in dem der Temperierprozess stattfinden soll.The display image of the Fig. 5 can be left via the key 28 without starting a tempering process, as the adjacent crossed out thermometer symbol illustrates. By pressing the button 25, a tempering process is started simultaneously with leaving the display image. In this case, the user arrives at the display image of Fig. 6 in which the parameters set for the tempering process can be seen in the display panel 19 of the compartment 6, in which the tempering process is to take place.

Aus unterschiedlichen Ablaufsteuerprogrammen, mit denen der Mikrocontroller 7 ausgestattet sein kann, ergeben sich unterschiedliche Arten der Handhabung des Geräts für einen Temperierprozess, für die im Folgenden Beispiele beschrieben werden.From different sequence control programs, with which the microcontroller 7 can be equipped, there are different ways of handling the device for a tempering process, examples of which will be described below.

Einer ersten Ausgestaltung zufolge geht das Gerät beim Einschalten zunächst für alle Fächer 5, 6, 7 in einen stationären Betriebszustand, in dem es die Fächer konstant auf einer Solltemperatur, wie auf dem Anzeigebild der Fig. 4 einstellbar, hält. Ein Benutzer kann das Gerät einige Zeit vor einem geplanten Temperierprozess einschalten, um sicherzustellen, dass die Fächer zu Beginn des Temperierprozesses auf besagten konstanten Sollwert abgekühlt sind. Dies ist insbesondere dann sinnvoll, wenn nur eine kleine Zahl von Flaschen temperiert werden soll. Zweckmäßigerweise ist die Solltemperatur für diesen stationären Kühlbetrieb gleich der Starttemperatur eines Temperierprozesses, d.h. gleich der Temperatur eines Kellers, aus dem die zu temperierenden Flaschen geholt werden; wie mit Bezug auf Fig. 5 beschrieben hat der Benutzer jedoch die Möglichkeit, beide Temperaturen unterschiedlich zu programmieren.According to a first embodiment, when the device is switched on, it initially goes into a stationary operating state for all compartments 5, 6, 7 in which the compartments remain constant at a setpoint temperature, as on the display image of the Fig. 4 adjustable, holds. A user The device can switch on for some time before a planned tempering process to ensure that the trays have cooled down to said constant setpoint value at the beginning of the tempering process. This is particularly useful if only a small number of bottles to be tempered. Conveniently, the setpoint temperature for this stationary cooling operation is equal to the starting temperature of a tempering process, ie equal to the temperature of a cellar, from which the bottles to be tempered are fetched; as related to Fig. 5 However, the user has the ability to program both temperatures differently.

Der Benutzer kann das Gerät auch erst nach dem Beladen mit Flaschen einschalten. In diesem Fall wird er im Allgemeinen nicht abwarten, bis die Fächer die Solltemperaturen für den stationären Kühlbetrieb erreicht haben, sondern den Temperierprozess umgehend einleiten.The user can also switch the device on only after being loaded with bottles. In this case, he will generally not wait until the compartments have reached the setpoint temperatures for the stationary cooling operation, but initiate the tempering process immediately.

Um den Temperierprozess für ein beladenes Fach, etwa das Fach 6 zu starten, wählt der Benutzer den Programmiermodus für den Temperierprozess des Fachs an, das heißt, er ruft das Anzeigebild der Fig. 5 auf. Wenn die Parameter des Temperierprozesses korrekt eingestellt sind, startet er diesen durch Betätigen der Taste 25. Auch wenn das Gerät erst unmittelbar vor Auslösen des Temperierprozesses eingeschaltet worden ist, dauert es nur wenige Minuten, bis die Verdampfer 15 abgekühlt sind und Kaltluft mit einer dem momentanen Temperatursollwert entsprechenden Temperatur in das Fach 6 geblasen wird. Zum Einregeln der Temperatur dient der dem Luftstrom des Ventilators 16 ausgesetzte Temperatursensor 13.In order to start the tempering process for a loaded compartment, such as the compartment 6, the user selects the programming mode for the tempering process of the compartment, that is, it calls the display image of the Fig. 5 on. If the parameters of the tempering process are set correctly, it starts by pressing the button 25. Even if the device has been switched on just before the tempering process, it only takes a few minutes for the evaporators 15 to cool down and cool air to be at the current one Temperature setpoint corresponding temperature is blown into the compartment 6. To regulate the temperature of the air flow of the fan 16 exposed temperature sensor 13 is used.

Einige Minuten später, vorzugsweise ca. 10 bis 15 Minuten nach dem Auslösen des Temperierprozesses, vergleicht der Mikrocontroller 12 die vom Temperatursensor 14 an einer vom Luftstrom des Ventilators 16 abgeschirmten Stelle, z.B. unmittelbar stromaufwärts vom Verdampfer15 oder in unmittelbarer Nähe der Flaschen, in der Kammer 6 erfasste Temperatur mit dem momentanen Temperatursollwert. Wenn eine Abweichung vom Temperatursollwert erfasst wird, so kann daraus gefolgert werden, dass die Temperatur der eingeladenen Flaschen nicht mit der programmierten Starttemperatur des Temperierprozesses übereinstimmt. Um in diesem Fall eine unnötige Verlängerung des Temperierprozesses oder einen schnellen Temperatursprung zu Beginn des Temperierprozesses zu vermeiden, gleicht der Mikrocontroller 12 die Solltemperatur an die von dem Temperatursensor 14 erfasste Temperatur an.A few minutes later, preferably about 10 to 15 minutes after the initiation of the tempering process, the microcontroller 12 compares the temperature sensor 14 at a shielded from the air flow of the fan 16, for example, immediately upstream of the evaporator 15 or in the immediate vicinity of the bottles in the chamber 6 detected temperature with the current temperature setpoint. If a deviation from the temperature setpoint is detected, then it can be concluded that the temperature of the loaded bottles does not match the programmed start temperature of the tempering process. In this case, an unnecessary extension of the tempering process or a rapid temperature jump at the beginning of the To avoid the tempering process, the microcontroller 12 adjusts the setpoint temperature to the temperature detected by the temperature sensor 14.

Spätestens ab diesem Zeitpunkt beginnt der Mikrocontroller 12 damit, die Solltemperatur mit einer festen Änderungsrate von 1 Grad Celsius pro Stunde an die programmierte Endtemperatur anzunähern. Diese Änderung kann kontinuierlich oder, wie in DE 103 58 732 A1 beschrieben, in mehreren diskreten Schritten erfolgen. Aus der vorgegebenen Änderungsrate der Temperatur, der momentanen Solltemperatur und der Endtemperatur des Temperierprozesses berechnet der Mikrocontroller 12 die Restdauer des Temperierprozesses und zeigt entweder diese oder eine Uhrzeit, zu der der Temperierprozess abgeschlossen ist, auf dem Anzeigeschirm 22 an. Fig. 7 zeigt eine solche Situation: ein Temperierprozess findet hier nur im Fach 6 statt; die Fächer 5, 7 sind stationär auf 12 Grad Celsius gehalten, wie in ihren Anzeigefeldern 20, 21 abzulesen ist. Auf dem Anzeigefeld 19 des Fachs 6 ist der Endzeitpunkt des Temperierprozesses, 12:51, die momentane Temperatur des Fachs 6, 13°C, sowie die Endtemperatur des Temperierprozesses, 17°C, ablesbar.At the latest from this point on, the microcontroller 12 begins to approach the setpoint temperature at a fixed rate of change of 1 degree Celsius per hour to the programmed end temperature. This change can be continuous or, as in DE 103 58 732 A1 described, take place in several discrete steps. From the predetermined rate of change of the temperature, the current setpoint temperature and the end temperature of the tempering process, the microcontroller 12 calculates the remaining duration of the tempering process and displays either this or a time at which the tempering process is completed on the display screen 22. Fig. 7 shows such a situation: a tempering process takes place here only in compartment 6; the compartments 5, 7 are held stationary at 12 degrees Celsius, as can be read in their display panels 20, 21. On the display panel 19 of the tray 6, the end time of the tempering, 12:51, the current temperature of the tray 6, 13 ° C, and the final temperature of the tempering, 17 ° C, readable.

Wenn die Endtemperatur erreicht ist, wird sie als konstante Solltemperatur des Fachs beibehalten, bis der Benutzer erneut den Programmiermodus für den Temperierprozess (Fig. 5) anwählt. Wenn er diesen Programmiermodus über die Taste 28 verlässt, verwendet der Mikrocontroller 12 wieder die in Fig. 4 programmierte Solltemperatur von 12°C. Wird der Programmiermodus über die Taste 25 verlassen, startet unmittelbar ein neuer Temperierprozess.When the final temperature is reached, it will be kept as a constant setpoint temperature of the compartment until the user again enters the programming mode for the tempering process ( Fig. 5 ). If he exits this programming mode via the key 28, the microcontroller 12 again uses the in Fig. 4 programmed setpoint temperature of 12 ° C. If the programming mode is exited via the button 25, a new tempering process starts immediately.

Mit einer anderen Version des Betriebsprogramms für den Mikrocontroller 12 ist folgender Ablauf möglich: der Benutzer schaltet das Gerät ein und aktiviert den Programmiermodus für den Temperierprozess entsprechend der Fig. 5. Wenn er diesen über die Taste 28 verlässt, bleibt das Gerät im stationären Kühlbetrieb, und das Fach 6 wird auf der für es in Fig. 4 eingestellten Temperatur gehalten. Bei Verlassen über die Taste 25 hingegen geht der Mikrocontroller in einen Temperierbereitschaftsmodus, in dem er zunächst die programmierte Starttemperatur des Temperierprozesses als eine konstante Solltemperatur annimmt. Dies gibt dem Benutzer die Möglichkeit, das Fach vor dem Beladen mit Flaschen auf die Kellertemperatur abzukühlen und es auf dieser Temperatur zu halten, solange weiter nichts geschieht. Der Temperierprozess wird ausgelöst, sobald der Mikrocontroller 12 das Schließen der Tür 2 des Fachs 6 erfasst, das heißt wenn davon ausgegangen werden kann, dass das Fach 6 mit Flaschen beladen worden ist. Der Temperierprozess läuft ab wie oben beschrieben. Um eine Verfälschung des vom Sensor 13 erfassten Temperaturwerts zu vermeiden, falls zum Beladen des Fachs 6 die Tür 2 mehrmals geöffnet und geschlossen wird, kann vorgesehen werden, dass mit jedem Türöffnen und -schließen der Temperierprozess zurückgesetzt wird und neu startet.With another version of the operating program for the microcontroller 12, the following sequence is possible: the user turns on the device and activates the programming mode for the tempering according to the Fig. 5 , If it leaves via key 28, the unit will remain in stationary cooling mode, and compartment 6 will be in place for in Fig. 4 set temperature. When leaving via the key 25, however, the microcontroller goes into a tempering standby mode in which it first assumes the programmed start temperature of the tempering as a constant set temperature. This gives the user the ability to cool the tray to the cellar temperature and keep it at that temperature before loading with bottles, as long as nothing else happens. The tempering process is triggered as soon as possible the microcontroller 12 detects the closing of the door 2 of the compartment 6, that is, if it can be assumed that the compartment 6 has been loaded with bottles. The tempering process takes place as described above. In order to avoid a falsification of the temperature value detected by the sensor 13, if the door 2 is opened and closed several times to load the compartment 6, it can be provided that the temperature control process is reset and restarted with each door opening and closing.

Einer bevorzugten Weiterbildung zufolge kann der Benutzer an dem Bedienfeld 10 eine Kopplung zwischen dem Temperierprozess und der Beleuchtung der Fächer 5, 6, 7 einstellen, durch die bei Erreichen der Endtemperatur des Temperierprozesses die Beleuchtung automatisch eingeschaltet wird, während sie, solange die Endtemperatur nicht erreicht ist, gesperrt bleibt. So wird der Benutzer durch das Angehen der Beleuchtung unmittelbar auf den Abschluss des Temperierprozesses aufmerksam gemacht. Flaschen, die gerade einen Temperierprozess durchmachen und ihre Genussreife noch nicht erreicht haben, bleiben im Dunkeln, so dass die Aufmerksamkeit der Gäste in erster Linie auf die verfügbaren Flaschen in einem anderen, beleuchteten Fach gelenkt wird.According to a preferred development, the user can set a coupling between the tempering process and the lighting of the compartments 5, 6, 7 on the control panel 10, by which the lighting is switched on automatically when the final temperature of the tempering process is reached, while it does not reach the end temperature is, remains locked. Thus, the user is made aware of the completion of the tempering process by addressing the lighting. Bottles that are currently undergoing a tempering process and have not yet reached their ripe for consumption, remain in the dark, so that the attention of the guests is directed primarily to the available bottles in another, illuminated tray.
