Der Weinlagerschrank kann auch mehr als zwei übereinander angeordnete Kompartimente aufweisen, die untereinander durch mehrere Trennböden voneinander getrennt sind. Bei der Wärmepumpe handelt es sich vorzugsweise um einen Kältemittelkreislauf mit einem Kompressor, einen Verflüssiger, einer Drossel und einem Verdampfer. Der kalte Wärmetauscher des Innenraums wird in diesem Fall durch den Verdampfer dargestellt. Selbstverständlich sind aber auch Varianten mit einer magnetokalorischen Kühlung oder einer thermoelektrischen Kühlung denkbar.The wine storage cabinet can also have more than two superimposed compartments, which are separated from each other by a plurality of shelves. The heat pump is preferably a refrigerant circuit with a compressor, a condenser, a throttle and an evaporator. The cold heat exchanger of the interior is represented in this case by the evaporator. Of course, variants with a magnetocaloric cooling or a thermoelectric cooling are also conceivable.

In einer Ausführungsform ist vorgesehen, dass der kalte Wärmetauscher im unteren Kompartiment und vorzugsweise an der Rückwand des unteren Kompartiments angeordnet ist, wobei vorzugsweise vorgesehen ist, dass der Weinlagerschrank nur einen im Innenraum angeordneten kalten Wärmetauscher umfasst. Soweit es sich bei der Wärmepumpe um einen Kältemittelkreislauf handelt, kann also nur ein im unteren Kompartiment angeordneter Verdampfer vorgesehen sein. Der Weinlagerschrank kann lediglich einen Kältemittelkreislauf mit einem Kompressor, einem Verflüssigker und einer Drossel umfassen.In one embodiment it is provided that the cold heat exchanger is arranged in the lower compartment and preferably on the rear wall of the lower compartment, it being preferably provided that the wine storage cabinet comprises only one arranged in the interior of a cold heat exchanger. As far as it is a refrigerant circuit in the heat pump, so only one arranged in the lower compartment evaporator can be provided.

In einer Ausführungsform ist vorgesehen, dass im ersten Kompartiment ein erster Innenraumventilator vorgesehen ist, der so angeordnet ist, dass bei dessen Betrieb Luft über den kalten Wärmetauscher geführt wird, wobei vorzugsweise vorgesehen ist, dass der kalte Wärmetauscher und vorzugsweise auch der erste Innenraumventilator in einem Kaltluftraum augeordnet sind, der hinter einer Kaltluftwand gebildet ist, die zumindest in einem Teilbereich des underen Kompartiments der Rückwand des Innenraums vorgelagert ist. Der Kaltluftraum umfasst eine Saugöffnung, die vorzugsweise oberhalb oder im oberen Bereich der Kaltluftwand angeordnet ist, sowie eine Drucköffnung, die vorzugsweise unterhalb oder im unteren Bereich der Kaltluftwand angeordnet ist. Entsprechend liegen ein in der Umgebung der Saugöffnung gebildeter Ansaugbereich vorzugsweise im hinteren oberen Abschnitt des unteren Kompartiments und ein in der Umgebung der Drucköffnung gebildeter Abgabebereich für Kaltluft vorzugsweise im hinteren oberen Abschnitt des unteren Kompartiments. Vorzugsweise ist innerhalb des Kaltluftraums der erste Innenraumventilator oberhalb des kalten Wärmetauschers angeordnet.In one embodiment, it is provided that in the first compartment, a first indoor fan is provided, which is arranged so that during operation air is passed through the cold heat exchanger, wherein it is preferably provided that the cold heat exchanger and preferably also the first indoor fan in a Cold air space are assigned, which is formed behind a cold air wall, which is at least in a partial region of the underen compartment upstream of the rear wall of the interior. The cold air space comprises a suction opening, which is preferably arranged above or in the upper region of the cold air wall, and a pressure opening, which is preferably arranged below or in the lower region of the cold air wall. Accordingly, a suction area formed in the vicinity of the suction opening is preferably located in the rear upper portion of the lower compartment and a discharge area for cold air formed in the vicinity of the pressure opening is preferably in the rear upper portion of the lower compartment. Preferably, the first indoor fan is disposed above the cold heat exchanger within the cold air space.

In einer Ausführungsform ist vorgesehen, dass der Steigschacht und der Fallschacht hinter einer Zwischenwand angeordnet sind, die zumindest im Bereich des oberen Kompartiments der Rückwand des Innenraums vorgelagert ist, wobei vorzugsweise vorgesehen ist, dass die Zwischenwand bis in das untere Kompartiment reicht und eine hinter dem Trennboden angeordnete Durchlassöffnung zwischen den Kompartimenten definiert. Die beiden Schächte können durch eine sich zwischen Zwischenwand und Rückwand erstreckende vertikale Trennwand voneinander getrennt sein.In one embodiment, it is provided that the riser shaft and the chute are arranged behind an intermediate wall, which is at least in the region of the upper compartment of the rear wall of the interior, wherein it is preferably provided that the intermediate wall extends into the lower compartment and one behind the Dividing bottom arranged passage opening defined between the compartments. The two shafts can be separated from one another by a vertical partition wall extending between intermediate wall and rear wall.

In einer Ausführungsform ist vorgesehen, dass der Steigschacht eine Einlassöffnung aufweist, durch die Luft vom Steigschacht in das obere Kompartiment entweichen kann, wobei vorzugsweise vorgesehen ist, dass die Einlassöffnung im oberen Bereich des zweiten Kompartiments angeordnet ist. Die Einlassöffnung kann sich in der Zwischenwand befinden. Der zweite Innenraumventilator kann innerhalb des Steigschachts angeordnet sein. Beispielsweise kann vorgesehen sein, dass der zweite Innenraumventilator direkt hinter der Einlassöffnung im Steigschacht angeordnet ist.In one embodiment, it is provided that the riser has an inlet opening through which air can escape from the riser into the upper compartment, wherein it is preferably provided that the inlet opening is arranged in the upper region of the second compartment. The inlet opening can be located in the intermediate wall. The second indoor fan can be inside the Steigschachts be arranged. For example, it can be provided that the second interior fan is arranged directly behind the inlet opening in the riser shaft.

In einer Ausführungsform ist vorgesehen, dass der Fallschacht eine Auslassöffnung aufweist, durch die Luft vom oberen Kompartiment in den Fallschacht entweichen kann, wobei vorzugsweise vorgesehen ist, dass die Auslassöffnung im unteren Bereich des zweiten Kompartiments angeordnet ist. Die Auslassöffnung kann sich in der Zwischenwand befinden. Die Anordnung der Auslassöffnung im unteren Bereich des zweiten Kompartiments ist bevorzugt, wobei in einer alternativen Ausgestaltung auch eine Anordnung der Auslassöffnung im mittleren oder oberen Bereich des zweiten Kompartiments vorgesehen sein kann.In one embodiment, it is provided that the chute has an outlet opening through which air can escape from the upper compartment into the chute, wherein it is preferably provided that the outlet opening is arranged in the lower area of the second compartment. The outlet opening can be located in the intermediate wall. The arrangement of the outlet opening in the lower region of the second compartment is preferred, wherein in an alternative embodiment, an arrangement of the outlet opening in the middle or upper region of the second compartment may be provided.

In einer Ausführungsform ist vorgesehen, dass eine Luftklappe vorgesehen ist, die ausgebildet ist, die Auslassöffnung reversibel zu verschließen, wobei vorzugsweise vorgesehen ist, dass die Luftklappe derart selbstschließend ausgebildet ist, dass sie durch Schwerkrafteinwirkung in den geschlossenen Zustand übergeht und bei Krafteinwirkung von vorne nach hinten in den Falschacht geschwenkt wird und dabei in einen geöffneten Zustand übergeht. Vorzugsweise ist die Luftklappe so ausgebildet, dass bereits eine sehr geringe Krafteinwirkung zum zumindest geringfügigen Öffnen der Luftklappe ausreicht. Insbesondere soll die bei Betrieb des zweiten Innenraumventilators entstehende kleine Druckdifferenz zwischen dem oberen Kompartiment und dem Fallkanal bereits ausreichen, um die Luftkappe zumindest geringfügig zu öffnen. Alternativ zu der beschriebenen passiven Luftklappe kann auch eine aktiv, beispielsweise elektronisch, magnetisch oder mechanisch gesteuerte Luftklappe zum Verschließen der Auslassöffnung verwendet werden. Dies kann gegebenenfalls zu einer verbesserten Funktionaltiät führen, erhöht aber gleichzeitig die Herstellungskosten, den Energiebedarf und gegebenenfalls den Wartungsbedarf.In one embodiment, it is provided that an air flap is provided, which is designed to reversibly close the outlet opening, wherein it is preferably provided that the air flap is formed so self-closing that it passes by gravity into the closed state and force from the front is pivoted into the crate at the back and goes into an open state. Preferably, the air flap is designed so that even a very small force is sufficient for at least slightly opening the air damper. In particular, the resulting during operation of the second indoor fan small pressure difference between the upper compartment and the fall channel is already sufficient to open the air cap at least slightly. As an alternative to the described passive air damper, it is also possible to use an active, for example electronically, magnetically or mechanically controlled damper for closing the outlet opening. This may possibly lead to an improved functionality, but at the same time increases the production costs, the energy requirement and possibly the need for maintenance.

In einer Ausführungsform ist vorgesehen, dass der Trennboden höhenverstellbar im Innenraum aufgenommen ist. So kann die Montagehöhe des Trennbodens vom Benutzer innerhalb eines gewissen Bereichs verstellt werden kann, beispielsweise durch Ablage des Trennbodens auf unterschiedlichen Rippen des Innenbehälters oder durch ein geeignetes Höhenverstellsystem. So können die relativen Volumina des wärmeren oberen Kompartiments und des kälteren unteren Kompartiments vom Benutzer je nach Bedarf verändert werden.In one embodiment, it is provided that the separating bottom is accommodated vertically adjustable in the interior. Thus, the mounting height of the partition can be adjusted by the user within a certain range, for example by placing the partition on different ribs of the inner container or by a suitable height adjustment system. Thus, the relative volumes of the warmer upper compartment and the colder lower compartment can be changed by the user as needed.

In einer Ausführungsform ist vorgesehen, dass es sich bei dem zweiten Innenraumventilator und/oder bei dem ersten Innenraumventilator um einen drehzahlgeregelten Ventilator handelt. Eine drehzahlgeregelte Ausbildung der beiden Innenraumventilatoren oder zumindest eines der beiden Innenraumventilatoren ermöglicht eine genauere Abstimmung des Betriebs der beiden Ventilatoren und mithin eine präzisere Kaltluftverteilung zwischen den beiden Kompartimenten.In one embodiment, it is provided that the second indoor fan and / or the first indoor fan is a speed-controlled fan. A speed-regulated design of the two indoor fans or at least one of the two indoor fans allows a more accurate tuning of the operation of the two fans and thus a more precise cold air distribution between the two compartments.

Je nach Betrieb des zweiten und gegebenenfalls ferner des ersten Innenraumventilatoren sind unterschiedliche Betriebsmodi realisierbar, um die Temperatur der beiden Kompartimente genau einstellen zu können. Die Innenraumventilatoren können bei Betrieb der Wärmepumpe oder bei Stillstand der Wärmepumpe jeweils für sich genommen oder gemeinsam betrieben werden, um eine gewünschte Gesamtkühlleistung oder Kaltluftverteilung zwischen den beiden Kompartimenten zu erreichen.Against the background mentioned above, the invention further relates to a method for operating a wine storage cabinet according to the invention, wherein the second indoor fan is operated to cool air from the lower compartment through the riser into the upper compartment and from the upper compartment through the drainage channel into the lower compartment to promote. Depending on the operation of the second and possibly further of the first indoor fans, different operating modes can be realized in order to be able to set the temperature of the two compartments precisely. When operating the heat pump or when the heat pump is at a standstill, the indoor fans can be taken alone or operated together in order to achieve a desired overall cooling capacity or cold air distribution between the two compartments.

Der Verdampfer 1 ist gemeinsam mit einem ersten Innenraumventilator 2 in einem gegenüber dem Innenraum mit einer ersten Zwischenwand abgetrennten ersten Luftleitbereich an der Rückwand des unteren Kompartiments 4 angeordnet. Der erste Innenraumventilator 2 ist so angeordnet, dass bei dessen Betrieb Luft aus dem Innenraum angesaugt, durch den Luftleitbereich und über den Verdampfer geführt und dann an das erste Kompartiment 3 abgegeben werden kann.The wine storage cabinet further comprises a refrigerant circuit comprising a compressor 6, a condenser, a throttle and an evaporator 1. The compressor 6 is arranged in a machine room which is located at the rear in the base area of the wine storage cabinet. The condenser not shown in detail in the figure can be arranged in a typical embodiment on the rear wall of the wine storage cabinet. The throttle may be a capillary line. The evaporator 1 is arranged on the rear wall of the lower compartment 4 together with a first interior fan 2 in a first air-conduction region which is separated from the interior by a first intermediate wall. The first indoor fan 2 is arranged so that during operation of the air sucked from the interior, passed through the air duct and the evaporator and then discharged to the first compartment 3.

Im Bereich des Trennbodens 10 befindet sich hinten im Weinlagerschrank eine Durchgangsöffnung, durch die Luft aus dem unteren Kompartiment 4 in das obere Kompartiment 3 sowie aus dem oberen Kompartiment 3 in das untere Kompartiment 4 strömen kann. An der Rückwand des oberen Kompartiments 4 ist ein gegenüber dem Innenraum mit einer zweiten Zwischenwand abgetrennter zweiter Luftleitbereich mit zwei nebeneinander angeordneten und durch eine Trennwand 7 voneinander getrennten Luftleitkanälen, nämlich einem Steigkanal 8 und einem Fallkanal 9 angeordnet.In the area of the separating tray 10, there is a passage opening at the rear in the wine storage cabinet, through which air can flow from the lower compartment 4 into the upper compartment 3 and from the upper compartment 3 into the lower compartment 4. On the rear wall of the upper compartment 4 a relative to the interior with a second intermediate wall separated second air duct with two juxtaposed and separated by a partition 7 air ducts, namely a riser 8 and a drop channel 9 is arranged.

Im oberen Bereich des Steigkanals 8 sind ein zweiter Innenraumventilator 11 und eine in der zweiten Zwischenwand gebildete Einlassöffnung vorgesehen. Der zweite Innenraumventilator 11 ist so angeordnet, dass bei dessen Betrieb Luft aus dem unteren Kompartiment 4 durch die Durchgangsöffnung und den Steigkanal 8 angesaugt und dann durch die Einlassöffnung an das obere Kompartiment 3 abgegeben werden kann. So kann auf energiesparende Weise relativ kalte Luft aus dem unteren Kompartiment 4 von oben in das obere Kompartiment 3 eingebracht werden. Diese kalte Luft kann dann innerhalb des oberen Kompartiments 3 langsam absinken, was zu einem insgesamt relativ homogenen Temperaturprofil innerhalb dieses Kompartiments 3 führt.In the upper region of the riser 8, a second indoor fan 11 and an inlet opening formed in the second intermediate wall are provided. The second indoor fan 11 is arranged so that during operation of the air from the lower compartment 4 can be sucked through the passage opening and the riser 8 and then discharged through the inlet opening to the upper compartment 3. Thus, in an energy-saving manner, relatively cold air from the lower compartment 4 can be introduced from the top into the upper compartment 3. This cold air can then slowly sink within the upper compartment 3, which leads to an overall relatively homogeneous temperature profile within this compartment 3.

Im unteren Bereich des Fallkanals 9 ist eine in der zweiten Zwischenwand gebildete Auslassöffnung 5 vorgesehen, die mit einer Luftklappe verschlossen ist. Die Luftklappe kann derart selbstschließend ausgebildet sein, dass sie durch Schwerkrafteinwirkung in den geschlossenen Zustand übergeht, aber bereits bei sehr geringer Krafteinwirkung zumindest ein Stück weit nach hinten geöffnet wird. Die bei Betrieb des zweiten Innenraumventilators 11 entstehende kleine Druckdifferenz zwischen dem oberen Kompartiment 3 und dem Fallkanal 9 reicht dann aus, um die Luftkappe zumindest geringfügig nach hinten zu drücken. Bei Betrieb des zweiten Innenraumventilators 11 wird also nicht nur relativ kalte Luft oben in das zweite Kompartiment 3 eingeleitet, sondern auch relativ warme weil bereits länger im oberen Kompartiment 3 befindliche Luft unten aus dem oberen Kompartiment 3 abgeleitet.In the lower region of the fall channel 9, an outlet opening 5 formed in the second intermediate wall is provided, which is closed by an air flap. The air damper can be designed so self-closing that it passes by gravity into the closed state, but at least a little way back is opened at very low force. The resulting during operation of the second indoor fan 11 small pressure difference between the upper compartment 3 and the drop channel 9 is then sufficient to push the air cap at least slightly backwards. When operating the second indoor fan 11 so not only relatively cold air is introduced at the top of the second compartment 3, but also relatively warm because already longer in the upper compartment 3 located air down from the upper compartment 3 derived.

Nämlich gelangt Luft aus dem unteren Bereich des oberen Kompartiments 3 durch die Auslassöffnung 5 in den Fallkanal 9 und fällt durch die Durchgangsöffnung in das untere Kompartiment 4 zurück. Der Fallkanal 9 mündet dabei im Ansaugbereich des ersten Innenraumventilators 2. Die Luftklappe verhindert, dass kalte Luft, die sich nach einer Nichtbetriebsphase des zweiten Innenraumventilators 11 nach und nach im unteren Bereich des oberen Kompartiments 3 sammelt, ungewollt aus diesem Kompartiment 3 entweicht, dass also im oberen Kompartiment 3 keine Kälte verloren geht.Namely, air passes from the lower portion of the upper compartment 3 through the outlet port 5 into the drain passage 9 and falls back through the passage opening into the lower compartment 4. The louver 9 opens in the intake of the first indoor fan 2. The air damper prevents cold air that gradually accumulates after a non-operating phase of the second indoor fan 11 in the lower part of the upper compartment 3, unintentionally escapes from this compartment 3, that is in the upper compartment 3 no cold is lost.

Zudem wird durch die Klappe verhindert, dass Kaltluft aus dem untereren Kompartiment 4 durch den Fallkanal 9 in das obere Fach gedrückt wird.In addition, the flap prevents cold air from the lower compartment 4 from being forced through the drop channel 9 into the upper compartment.

Je nach Betrieb der Innenraumventilatoren sind also mehrere Betriebsmodi realisierbar, um die Temperatur der beiden Kompartimente 3 und 4 genau einstellen zu können. Wird nur der erste Innenraumventilator 2 betrieben, so wird, vorausgesetzt der Kompressor 6 wird betrieben, die Luft im unteren Kompartiment 4 gekühlt, während die Lufttemperatur im oberen Kompartiment konstant gehalten wird. Werden beide Innenraumventilatoren 2 und 11 betrieben, so wird einerseits relativ kalte Luft aus dem unteren Kompartiment 4 in das obere Kompartiment 3 geleitet und relativ warme Luft aus dem oberen Kompartiment 3 in das untere Kompartiment 4 geleitet. Andererseits werden, wiederum vorausgesetzt der Kompressor 6 wird betrieben, die aus dem oberen Kompartiment 3 in das untere Kompartiment 4 gelangende Luft sowie auch originär im unteren Kompartiment 4 befindliche Luft ebenfalls gekühlt. Wird nur der zweite Innenraumventilator 11 betrieben, so gelangt relativ kalte Luft aus dem unteren Kompartiment 4 in das obere Kompartiment 3 und relativ warme Luft aus dem oberen Kompartiment 3 in das untere Kompartiment 4. Es erfolgt also eine Erwärmung des unteren Kompartiments 4 und eine Abkühlung des oberen Kompartiments 3. Generell kann aber die Temperatur des oberen Kompartiments 3 nie niedriger sein als die Temperatur des unteren Kompartiments 4.Depending on the operation of the indoor fans so several modes of operation can be realized in order to adjust the temperature of the two compartments 3 and 4 can be accurate. If only the first indoor fan 2 is operated, provided that the compressor 6 is operated, the air in the lower compartment 4 is cooled, while the air temperature in the upper compartment is kept constant. If both indoor fans 2 and 11 are operated, on the one hand relatively cold air is conducted from the lower compartment 4 into the upper compartment 3 and relatively warm air is conducted from the upper compartment 3 into the lower compartment 4. On the other hand, again provided that the compressor 6 is operated, the air coming from the upper compartment 3 into the lower compartment 4 as well as the air originally located in the lower compartment 4 are also cooled. If only the second indoor fan 11 is operated, then relatively cold air from the lower compartment 4 enters the upper compartment 3 and relatively warm air from the upper compartment 3 into the lower compartment 4. Thus, a heating of the lower compartment 4 and a cooling takes place of the upper compartment 3. In general, however, the temperature of the upper compartment 3 can never be lower than the temperature of the lower compartment 4.

Die Lage der Auslassöffnung 5 in der zweiten Zwischenwand ist so gewählt, dass eine gewisse vertikale Verstellung des Trennbodens 10 möglich ist, ohne dass die Auslassöffnung 5 den Bereich des oberen Kompartiments 3 verlässt. So ist eine gewisse Variabilität in der Volumensverteilung zwischen den Kompartimenten 3 und 4 möglich, um dem Kunden beispielsweise zu ermöglichen, wahlweise mehr Volumen für die Lagerung von Rotweinen oder für die Lagerung von Weißweinen zur Verfügung zu haben.The position of the outlet opening 5 in the second intermediate wall is selected such that a certain vertical adjustment of the separating bottom 10 is possible without the outlet opening 5 leaving the area of the upper compartment 3. Thus, some variability in the volume distribution between compartments 3 and 4 is possible, for example, to allow the customer to optionally have more volume available for the storage of red wines or for the storage of white wines.

Eine mögliche Abwandlung des Weinlagerschranks kann dahin gehen, dass auf die Luftklappe verzichtet wird. In diesem Fall kann die Auslassöffnung 5 gegebenenfalls nicht im unteren Bereich sondern im oberen Bereich des Fallkanals angeordnet werden. Dies kann aber jeweils zu einem etwas größeren Energiebedarf des Weinlagerschranks und zu einer etwas ungenaueren Temperaturregelung führen.A possible modification of the wine storage cabinet may be that the air damper is omitted. In this case, the outlet opening 5 may optionally not be arranged in the lower region but in the upper region of the drop channel. However, this can lead in each case to a somewhat greater energy requirement of the wine storage cabinet and to a somewhat inaccurate temperature control.
