Definitions
- the invention relates to a bottom group of a housing having a tumble dryer with at least one below a heat source and a heat sink of a heat pump of the tumble dryer separating shelf, on which the heat source and the heat sink stand up.
- a known tumble dryer in particular a condensation dryer, comprises a heat pump with two heat exchangers, namely a heat-emitting heat source and a heat-receiving heat sink, wherein process air used for drying laundry is heated by the heat source and supplied to the laundry for absorbing moisture therefrom, and the moisture absorbed during the drying of laundry is condensed by means of the heat sink to which the process air laden with the moisture is fed.
- a clothes dryer with heat pump has a much lower energy consumption than a clothes dryer without heat pump. The energy efficiency of a clothes dryer with heat pump increases with the volume of heat exchangers used in the heat pump, ie the volume of the heat source and the heat sink. For the arrangement of the heat exchanger of the heat pump but within the housing a limited installation space available, which is limited by adjacent to the heat pump assemblies, for example by a laundry drum driving belt or a self-cleaning system for cleaning a heat exchanger of the heat pump.
- a heat pump often used in a tumble dryer contains a refrigerant which circulates in a self-contained cycle and thereby cyclically evaporates while absorbing heat and is condensed with the release of heat.
- the evaporation of the refrigerant takes place predominantly in the heat sink. This can therefore also be referred to as an evaporator or evaporator.
- the refrigerant then passes to a compressor, where it is compressed.
- the compressor is also the drive that drives the refrigerant through its circulation. From the compressor, the compressed refrigerant reaches the heat source, where it is liquefied with the release of heat.
- This heat source is therefore also to be referred to as a condenser or condenser.
- the liquefied refrigerant passes into a relaxation device, in particular a valve, a diaphragm or a capillary, in which its internal pressure is reduced and it already partly turned back into gas. The resulting mixture of liquid and gas gets back to the heat sink.
- a corresponding dryer with a heat pump comprehensive floor group is for example off DE 10 2008 044 277 A1 known.
- a liquid tank is usually arranged on the bottom side, in which condensing water can accumulate on the heat sink of the heat pump. If a tumble dryer additionally has a self-cleaning system for cleaning a heat exchanger of the heat pump, the liquid pool is also used to collect the flushing fluid used in this case.
- the heat exchangers of the heat pump are usually arranged above the liquid tank, for which purpose above the liquid tank a separating floor can be arranged, on which the heat exchangers stand up. The space below the heat exchanger or the separating tray is thus limited by the liquid pool.
- the object of the invention is to increase the energy efficiency of a heat pump having a tumble dryer and to specify a corresponding floor group.
- the floor assembly according to the invention of a housing having a tumble dryer with at least one below a heat source and a heat sink of a heat pump of the tumble dryer separating shelf on which the heat source and the heat sink stand up is characterized in that in the separating bottom at least a trough-like, waterproof and in the direction the heat source open formed recess is formed, wherein a bottom of the recess is completely below a maximum diesstechniks spall House a bottom side disposed below the partition floor liquid tank and the heat source rests on the ground.
- the bottom of the depression is located completely below the maximum liquid filling height of the liquid basin arranged below the bottom on the bottom side.
- a bottom-side portion of the heat source disposed in the recess can be positioned lower than is possible with a conventional partition floor which would be located entirely above a maximum liquid level of a liquid pool of the clothes dryer.
- the floor assembly according to the invention can thus be developed for the heat source additional space within the liquid pool.
- a heat source with a height that is greater than a height of a heat source that could be installed in the same tumble dryer without the floor assembly according to the invention can be installed in a tumble dryer.
- the possible size of the heat source depends inter alia on how far the bottom of the depression is located below the maximum liquid filling height of the liquid pool.
- the heat source could, at a high, in particular maximum, liquid level in the liquid tank, come into direct contact with a liquid present in the liquid tank. This would be even more likely in a tumble dryer equipped with a self-cleaning system for cleaning at least one heat exchanger of its heat pump, since such a dryer may produce a greater amount of liquid in the liquid pool at least during a corresponding self-cleaning.
- a corresponding immersion of the heat source in a liquid contained in the liquid pool would be associated with a loss of power of the heat source, since on the one hand, the liquid the heat source and thereby indirectly abküh the process air to be heated by her len and on the other hand, the relative humidity in the vicinity of the heat source would be increased.
- the floor assembly according to the invention or its arrangement on a tumble dryer a corresponding loss of power of the heat source, and thus of the heat pump as a whole, can be effectively avoided.
- a clothes dryer of the aforementioned type is a household appliance, which is set up using condensation drying for drying wet and / or wet laundry.
- the tumble dryer may be formed, for example, as a drum dryer, drying oven, washer-dryer or the like.
- At least one securing means for securing a positioning of the heat source relative to the bottom of the recess is arranged on a side of the bottom of the recess facing the heat source.
- the securing means may be formed as a closed, substantially perpendicular from the bottom of the recess projecting wall.
- a plurality of separate securing means in the form of protruding perpendicularly from the bottom of the recess protrusions may be arranged at the bottom of the recess.
- the bottom of the recess is formed supporting.
- the heat source can be placed on the bottom of the recess and carried by this and held.
- the bottom of the recess or the separating tray is to be provided for this purpose with a suitable dimensional stability.
- reinforcing ribs or the like can be arranged on the separating bottom, in particular on the bottom side.
- a further advantageous embodiment provides that the separating tray is disposed below the heat source and the heat sink of the heat pump, wherein at least one open in the direction of the evaporator lowering is formed on the separating bottom, so that a bottom of the lowering completely below the maximum diesstechniks circullliere the bottom side located below the partition floor arranged liquid pool of the clothes dryer. Since the bottom of the lowering is arranged on the bottom side below the maximum liquid filling level of the liquid basin arranged below the separating bottom, a bottom-side portion of the heat sink or the heat sink arranged in the recess can be arranged lower overall than would be possible with a conventional separating tray completely above a maximum copesstechniks circullliere a liquid pool of a clothes dryer would be arranged.
- a heat sink with a height that is greater than a height of a heat sink which could be installed in the same tumble dryer without the floor assembly according to this embodiment, can be installed in a tumble dryer.
- This is also accompanied by an increase in the energy efficiency of a laundry dryer equipped with a floor assembly according to the invention.
- the possible size of the heat sink depends among other things on how far the bottom of the sink is located below the maximum liquid level of the liquid pool.
- the lowering does not have to be formed in a watertight and trough-like manner according to the recess, since physical contact between the heat sink and a liquid contained in the liquid tank or consequent cooling of the evaporator does not adversely affect the cooling performance of the heat sink.
- the relative humidity in the vicinity of the heat sink anyway relatively high, so that an increase in the relative humidity in their environment by the presence of existing in the liquid pool liquid can be almost excluded.
- the lowering may alternatively be formed trough-like and waterproof according to the depression.
- At least one further securing means for securing a positioning of the heat sink relative to the bottom of the lowering is arranged on a side of a bottom of the depression facing the heat sink.
- This is particularly advantageous in a tumble dryer in the form of a drum dryer or a washer dryer because of the vibrations occurring during operation of a drum dryer or washer dryer.
- the further securing means By means of the further securing means, a proper positioning of the portion of the heat sink relative to the bottom of the reduction can be reliably ensured under such loads, which improves the robustness of a suitably equipped tumble dryer and prevents noise within the tumble dryer by abutting each other not intentionally interconnected components.
- the securing means for example, a positive connection between the separating tray and the heat sink can be produced.
- the securing means may be formed as a closed, substantially perpendicular from the bottom of the lowering projecting wall.
- a plurality of separate securing means in the form of protruding perpendicularly from the bottom of the lowering protrusions may be arranged at the bottom of the lowering.
- the bottom of the sink is designed to be load-bearing.
- the heat sink can be placed on the floor of the lowering and carried and held by this.
- the bottom of the lowering or the separating tray is to be provided for this purpose with a suitable dimensional stability.
- reinforcing ribs or the like can be arranged on the bottom of the lowering, in particular on the bottom side.
- At least one opening is formed at the bottom of the depression. Should it happen during operation of a tumble dryer, that the heat sink temporarily partially immersed in a liquid contained in the liquid tank, this configuration at falling liquid level in the liquid tank, a liquid located on the bottom of the sink drain through the opening again and into the liquid pool reach.
- the opening means may be provided, which allow only a drainage of the liquid, but prevent the liquid from entering the area above the separating bottom. If the opening is made relatively large, can also ambient air between the bottom of the Heat sink and the top of the bottom of the sink pass, whereby these areas can be dried, which for example prevents odor or mold on these components of a tumble dryer.
- the heat source is a condenser and the heat sink is an evaporator for a refrigerant circulating in the heat pump.
- the invention also provides a tumble dryer comprising the underbody of the invention or one of its described embodiments.
- This dryer is connected in accordance with the above mentioned floor covering groups of the invention.

Description
Die Erfindung betrifft eine Bodengruppe eines ein Gehäuse aufweisenden Wäschetrockners mit wenigstens einem unterhalb einer Wärmequelle und einer Wärmesenke einer Wärmepumpe des Wäschetrockners angeordneten Trennboden, auf welchem die Wärmequelle und die Wärmesenke aufstehen.The invention relates to a bottom group of a housing having a tumble dryer with at least one below a heat source and a heat sink of a heat pump of the tumble dryer separating shelf, on which the heat source and the heat sink stand up.
Ein bekannter Wäschetrockner, insbesondere Kondensationstrockner, umfasst eine Wärmepumpe mit zwei Wärmetauschern, nämlich einer Wärme abgebenden Wärmequelle und einer Wärme aufnehmenden Wärmesenke, wobei zum Trocknen von Wäsche eingesetzte Prozessluft mittels der Wärmequelle aufgeheizt und der Wäsche zum Aufnehmen von Feuchtigkeit aus dieser zugeführt wird, und die bei der Trocknung von Wäsche aufgenommene Feuchtigkeit mittels der Wärmesenke, welcher die mit der Feuchtigkeit beladene Prozessluft zugeleitet wird, kondensiert wird. Ein Wäschetrockner mit Wärmepumpe hat einen deutlich niedrigeren Energieverbrauch als ein Wäschetrockner ohne Wärmepumpe. Die Energieeffizienz eines Wäschetrockners mit Wärmepumpe steigt mit dem Volumen der in der Wärmepumpe verwendeten Wärmetauscher, also dem Volumen der Wärmequelle und der Wärmesenke. Für die Anordnung der Wärmetauscher der Wärmepumpe steht aber innerhalb des Gehäuses ein begrenzter Einbauraum zur Verfügung, der durch an die Wärmepumpe angrenzende Baugruppen, beispielsweise durch einen eine Wäschetrommel antreibenden Riemen oder ein Selbstreinigungssystem zum Reinigen eines Wärmetauschers der Wärmepumpe, eingeschränkt ist.A known tumble dryer, in particular a condensation dryer, comprises a heat pump with two heat exchangers, namely a heat-emitting heat source and a heat-receiving heat sink, wherein process air used for drying laundry is heated by the heat source and supplied to the laundry for absorbing moisture therefrom, and the moisture absorbed during the drying of laundry is condensed by means of the heat sink to which the process air laden with the moisture is fed. A clothes dryer with heat pump has a much lower energy consumption than a clothes dryer without heat pump. The energy efficiency of a clothes dryer with heat pump increases with the volume of heat exchangers used in the heat pump, ie the volume of the heat source and the heat sink. For the arrangement of the heat exchanger of the heat pump but within the housing a limited installation space available, which is limited by adjacent to the heat pump assemblies, for example by a laundry drum driving belt or a self-cleaning system for cleaning a heat exchanger of the heat pump.
Eine in einem Wäschetrockner oft eingesetzte Wärmepumpe enthält ein Kältemittel, welches in einem in sich geschlossenen Kreislauf umläuft und dabei zyklisch unter Aufnahme von Wärme verdampft und unter Abgabe von Wärme kondensiert wird. Das Verdampfen des Kältemittels geschieht überwiegend in der Wärmesenke. Diese kann deshalb auch als Verdampfer oder Evaporator bezeichnet werden. Ihr fließt das Kältemittel als Gemisch aus Flüssigkeit und Gas zu. Als Gas gelangt das Kältemittel dann zu einem Kompressor, in dem es komprimiert wird. Der Kompressor ist auch der Antrieb, der das Kältemittel durch seinen Kreislauf treibt. Vom Kompressor gelangt das komprimierte Kältemittel zu der Wärmequelle, in der es unter Abgabe von Wärme verflüssigt wird. Diese Wärmequelle ist deshalb auch als Verflüssiger oder Kondensator zu bezeichnen. Aus der Wärmequelle gelangt das verflüssigte Kältemittel in ein Entspannungsorgan, insbesondere ein Ventil, eine Blende oder eine Kapillare, in welcher sein Binnendruck herabgesetzt wird und es sich schon teilweise wieder in Gas verwandelt. Das so entstandene Gemisch aus Flüssigkeit und Gas gelangt wieder zur Wärmesenke.A heat pump often used in a tumble dryer contains a refrigerant which circulates in a self-contained cycle and thereby cyclically evaporates while absorbing heat and is condensed with the release of heat. The evaporation of the refrigerant takes place predominantly in the heat sink. This can therefore also be referred to as an evaporator or evaporator. It flows to the refrigerant as a mixture of liquid and gas. As a gas, the refrigerant then passes to a compressor, where it is compressed. The compressor is also the drive that drives the refrigerant through its circulation. From the compressor, the compressed refrigerant reaches the heat source, where it is liquefied with the release of heat. This heat source is therefore also to be referred to as a condenser or condenser. From the heat source, the liquefied refrigerant passes into a relaxation device, in particular a valve, a diaphragm or a capillary, in which its internal pressure is reduced and it already partly turned back into gas. The resulting mixture of liquid and gas gets back to the heat sink.
Ein entsprechender Wäschetrockner mit einer eine Wärmepumpe umfassenden Bodengruppe ist beispielsweise aus
In einem Wäschetrockner mit Wärmepumpe ist bodenseitig üblicherweise ein Flüssigkeitsbecken angeordnet, in welchem sich an der Wärmesenke der Wärmepumpe kondensierendes Wasser ansammeln kann. Weist ein Wäschetrockner zusätzlich ein Selbstreinigungssystem zum Reinigen eines Wärmetauschers der Wärmepumpe auf, wird das Flüssigkeitsbecken auch zum Auffangen des hierbei verwendeten Spülfluids verwendet. Die Wärmetauscher der Wärmepumpe sind üblicherweise oberhalb des Flüssigkeitsbeckens angeordnet, wozu oberhalb des Flüssigkeitsbeckens ein Trennboden angeordnet sein kann, auf dem die Wärmetauscher aufstehen. Der Bauraum unterhalb der Wärmetauscher bzw. des Trennbodens ist somit durch das Flüssigkeitsbecken begrenzt.In a clothes dryer with heat pump, a liquid tank is usually arranged on the bottom side, in which condensing water can accumulate on the heat sink of the heat pump. If a tumble dryer additionally has a self-cleaning system for cleaning a heat exchanger of the heat pump, the liquid pool is also used to collect the flushing fluid used in this case. The heat exchangers of the heat pump are usually arranged above the liquid tank, for which purpose above the liquid tank a separating floor can be arranged, on which the heat exchangers stand up. The space below the heat exchanger or the separating tray is thus limited by the liquid pool.
Aufgabe der Erfindung ist es, die Energieeffizienz eines eine Wärmepumpe aufweisenden Wäschetrockners zu steigern und dazu eine entsprechende Bodengruppe anzugeben.The object of the invention is to increase the energy efficiency of a heat pump having a tumble dryer and to specify a corresponding floor group.
Diese Aufgabe wird durch die unabhängigen Patentansprüche gelöst. Vorteilhafte Ausgestaltungen sind in den abhängigen Patentansprüchen wiedergegeben, welche jeweils für sich genommen oder in verschiedener Kombination miteinander einen weiterbildenden, insbesondere auch bevorzugten oder vorteilhaften Aspekt der Erfindung darstellen können.This object is solved by the independent claims. Advantageous embodiments are given in the dependent claims, which each taken alone or in various combinations with each other can represent a further developing, in particular preferred or advantageous aspect of the invention.
Die erfindungsgemäße Bodengruppe eines ein Gehäuse aufweisenden Wäschetrockners mit wenigstens einem unterhalb einer Wärmequelle und einer Wärmesenke einer Wärmepumpe des Wäschetrockners angeordneten Trennboden, auf welchem die Wärmequelle und die Wärmesenke aufstehen, zeichnet sich dadurch aus, dass in dem Trennboden wenigstens eine wannenartige, wasserdichte und in Richtung der Wärmequelle offen ausgebildete Vertiefung ausgebildet ist, wobei ein Boden der Vertiefung vollständig unterhalb einer maximalen Flüssigkeitsfüllhöhe eines bodenseitig unterhalb des Trennbodens angeordneten Flüssigkeitsbeckens liegt und die Wärmequelle auf dem Boden aufsteht.The floor assembly according to the invention of a housing having a tumble dryer with at least one below a heat source and a heat sink of a heat pump of the tumble dryer separating shelf on which the heat source and the heat sink stand up, is characterized in that in the separating bottom at least a trough-like, waterproof and in the direction the heat source open formed recess is formed, wherein a bottom of the recess is completely below a maximum Flüssigkeitsfüllhöhe a bottom side disposed below the partition floor liquid tank and the heat source rests on the ground.
Erfindungsgemäß befindet sich der Boden der Vertiefung vollständig unterhalb der maximalen Flüssigkeitsfüllhöhe des bodenseitig unterhalb des Trennbodens angeordneten Flüssigkeitsbeckens. Da die Vertiefung zudem wannenartig und wasserdicht ausgebildet ist, kann ein in der Vertiefung angeordneter bodenseitiger Abschnitt der Wärmequelle tiefer angeordnet werden, als es mit einem herkömmlichen Trennboden möglich ist, welcher vollständig oberhalb einer maximalen Flüssigkeitsfüllhöhe eines Flüssigkeitsbeckens des Wäschetrockners angeordnet wäre. Bei Verwendung der erfindungsgemäßen Bodengruppe kann somit für die Wärmequelle zusätzlicher Bauraum innerhalb des Flüssigkeitsbeckens erschlossen werden. Hierdurch kann in einem Wäschetrockner eine Wärmequelle mit einer Bauhöhe verbaut werden, die größer als eine Bauhöhe einer Wärmequelle ist, der in demselben Wäschetrockner ohne die erfindungsgemäße Bodengruppe verbaut werden könnte. Dies geht mit einer Steigerung der Energieeffizienz eines mit einer erfindungsgemäßen Bodengruppe ausgestatteten Wäschetrockners einher. Die mögliche Größe der Wärmequelle hängt unter anderem davon ab, wie weit der Boden der Vertiefung unterhalb der maximalen Flüssigkeitsfüllhöhe des Flüssigkeitsbeckens angeordnet ist.According to the invention, the bottom of the depression is located completely below the maximum liquid filling height of the liquid basin arranged below the bottom on the bottom side. Moreover, since the recess is trough-shaped and waterproof, a bottom-side portion of the heat source disposed in the recess can be positioned lower than is possible with a conventional partition floor which would be located entirely above a maximum liquid level of a liquid pool of the clothes dryer. When using the floor assembly according to the invention can thus be developed for the heat source additional space within the liquid pool. In this way, a heat source with a height that is greater than a height of a heat source that could be installed in the same tumble dryer without the floor assembly according to the invention can be installed in a tumble dryer. This is accompanied by an increase in the energy efficiency of a laundry dryer equipped with a floor assembly according to the invention. The possible size of the heat source depends inter alia on how far the bottom of the depression is located below the maximum liquid filling height of the liquid pool.
Wäre die Vertiefung des erfindungsgemäßen Trennbodens nicht wannenartig und wasserdicht ausgebildet, könnte die Wärmequelle bei einem hohen, insbesondere maximalen, Flüssigkeitsfüllstand in dem Flüssigkeitsbecken in unmittelbaren Kontakt mit einer in dem Flüssigkeitsbecken vorhandenen Flüssigkeit gelangen. Dies wäre umso wahrscheinlicher bei einem Wäschetrockner, der mit einem Selbstreinigungssystem zum Reinigen zumindest eines Wärmetauschers seiner Wärmepumpe ausgestattet ist, da bei einem solchen Wäschetrockner zumindest während einer entsprechenden Selbstreinigung eine größere Menge an Flüssigkeit in dem Flüssigkeitsbecken anfallen kann. Ein entsprechendes Eintauchen der Wärmequelle in eine in dem Flüssigkeitsbecken enthaltene Flüssigkeit wäre mit einem Leistungsverlust der Wärmequelle verbunden, da einerseits die Flüssigkeit die Wärmequelle und hierdurch indirekt die von ihr aufzuheizende Prozessluft abküh len würde und andererseits die relative Luftfeuchtigkeit in der Umgebung der Wärmequelle erhöht werden würde. Mit der erfindungsgemäßen Bodengruppe bzw. deren Anordnung an einem Wäschetrockner kann ein entsprechender Leistungsverlust der Wärmequelle, und damit der Wärmepumpe insgesamt, wirksam vermieden werden.If the recess of the separating tray according to the invention were not trough-shaped and waterproof, the heat source could, at a high, in particular maximum, liquid level in the liquid tank, come into direct contact with a liquid present in the liquid tank. This would be even more likely in a tumble dryer equipped with a self-cleaning system for cleaning at least one heat exchanger of its heat pump, since such a dryer may produce a greater amount of liquid in the liquid pool at least during a corresponding self-cleaning. A corresponding immersion of the heat source in a liquid contained in the liquid pool would be associated with a loss of power of the heat source, since on the one hand, the liquid the heat source and thereby indirectly abküh the process air to be heated by her len and on the other hand, the relative humidity in the vicinity of the heat source would be increased. With the floor assembly according to the invention or its arrangement on a tumble dryer, a corresponding loss of power of the heat source, and thus of the heat pump as a whole, can be effectively avoided.
Ein Wäschetrockner der vorgenannten Gattung ist ein Haushaltsgerät, welches unter Verwendung von Kondensationstrocknung zum Trocknen von nasser und/oder feuchter Wäsche eingerichtet ist. Der Wäschetrockner kann beispielsweise als Trommeltrockner, Trockenschrank, Waschtrockner oder dergleichen ausgebildet sein.A clothes dryer of the aforementioned type is a household appliance, which is set up using condensation drying for drying wet and / or wet laundry. The tumble dryer may be formed, for example, as a drum dryer, drying oven, washer-dryer or the like.
Gemäß einer vorteilhaften Ausgestaltung ist an einer der Wärmequelle zugewandten Seite des Bodens der Vertiefung wenigstens ein Sicherungsmittel zum Sichern einer Positionierung der Wärmequelle relativ zu dem Boden der Vertiefung angeordnet. Dies ist insbesondere bei einem Wäschetrockner in Form eines Trommeltrockners oder eines Waschtrockners wegen der im Betrieb eines Trommeltrockners bzw. Waschtrockners auftretenden Vibrationen von Vorteil. Mittels des Sicherungsmittels kann eine bestimmungsgemäße Positionierung der Wärmequelle relativ zu dem Boden der Vertiefung unter derartigen Belastungen zuverlässig erzielt werden, was die Robustheit eines entsprechend ausgestatteten Wäschetrockners verbessert und eine Geräuschbildung innerhalb des Wäschetrockners durch ein Aneinanderstoßen von nicht bestimmungsgemäß miteinander verbundenen Bauteilen verhindert. Mittels des Sicherungsmittels kann beispielsweise eine formschlüssige Verbindung zwischen dem Trennboden und der Wärmequelle hergestellt werden. Das Sicherungsmittel kann als geschlossene, im Wesentlichen senkrecht von dem Boden der Vertiefung abstehende Wandung ausgebildet sein. Alternativ können mehrere separate Sicherungsmittel in Form von senkrecht von dem Boden der Vertiefung abstehenden Vorsprüngen an dem Boden der Vertiefung angeordnet sein.According to an advantageous embodiment, at least one securing means for securing a positioning of the heat source relative to the bottom of the recess is arranged on a side of the bottom of the recess facing the heat source. This is particularly advantageous in a tumble dryer in the form of a drum dryer or a washer dryer because of the vibrations occurring during operation of a drum dryer or washer dryer. By means of the securing means, a proper positioning of the heat source relative to the bottom of the recess can be reliably achieved under such loads, which improves the robustness of a suitably equipped tumble dryer and prevents noise within the tumble dryer by abutting against each other not intentionally interconnected components. By means of the securing means, for example, a positive connection between the separating tray and the heat source can be produced. The securing means may be formed as a closed, substantially perpendicular from the bottom of the recess projecting wall. Alternatively, a plurality of separate securing means in the form of protruding perpendicularly from the bottom of the recess protrusions may be arranged at the bottom of the recess.
Nach einer weiteren vorteilhaften Ausgestaltung ist der Boden der Vertiefung tragend ausgebildet. Hierdurch kann die Wärmequelle auf den Boden der Vertiefung aufgestellt und von diesem getragen und gehalten werden. Der Boden der Vertiefung bzw. der Trennboden ist hierzu mit einer geeigneten Formstabilität zu versehen. Hierzu können an dem Trennboden, insbesondere bodenseitig, Verstärkungsrippen oder dergleichen angeordnet sein.According to a further advantageous embodiment, the bottom of the recess is formed supporting. As a result, the heat source can be placed on the bottom of the recess and carried by this and held. The bottom of the recess or the separating tray is to be provided for this purpose with a suitable dimensional stability. For this purpose, reinforcing ribs or the like can be arranged on the separating bottom, in particular on the bottom side.
Eine weitere vorteilhafte Ausgestaltung sieht vor, dass der Trennboden unterhalb der Wärmequelle und der Wärmesenke der Wärmepumpe angeordnet ist, wobei an dem Trennboden wenigstens eine in Richtung des Evaporators offen ausgebildete Absenkung ausgebildet ist, so dass ein Boden der Absenkung vollständig unterhalb der maximalen Flüssigkeitsfüllhöhe des bodenseitig unterhalb des Trennbodens angeordneten Flüssigkeitsbeckens des Wäschetrockners liegt. Da der Boden der Absenkung vollständig bodenseitig unterhalb der maximalen Flüssigkeitsfüllhöhe des bodenseitig unterhalb des Trennbodens angeordneten Flüssigkeitsbeckens angeordnet ist, kann ein in der Absenkung angeordneter bodenseitiger Abschnitt der Wärmesenke bzw. die Wärmesenke insgesamt tiefer angeordnet werden, als es mit einem herkömmlichen Trennboden möglich wäre, welcher vollständig oberhalb einer maximalen Flüssigkeitsfüllhöhe eines Flüssigkeitsbeckens eines Wäschetrockners angeordnet wäre. Bei Verwendung der erfindungsgemäßen Bodengruppe kann somit auch für die Wärmesenke zusätzlicher Bauraum innerhalb des Flüssigkeitsbeckens erschlossen werden. Hierdurch kann in einem Wäschetrockner eine Wärmesenke mit einer Bauhöhe verbaut werden, die größer als eine Bauhöhe einer Wärmesenke ist, die in demselben Wäschetrockner ohne die Bodengruppe gemäß dieser Ausgestaltung verbaut werden könnte. Dies geht ebenfalls mit einer Steigerung der Energieeffizienz eines mit einer erfindungsgemäßen Bodengruppe ausgestatteten Wäschetrockners einher. Die mögliche Größe der Wärmesenke hängt unter anderen davon ab, wie weit der Boden der Absenkung unterhalb der maximalen Flüssigkeitsfüllhöhe des Flüssigkeitsbeckens angeordnet ist.A further advantageous embodiment provides that the separating tray is disposed below the heat source and the heat sink of the heat pump, wherein at least one open in the direction of the evaporator lowering is formed on the separating bottom, so that a bottom of the lowering completely below the maximum Flüssigkeitsfüllhöhe the bottom side located below the partition floor arranged liquid pool of the clothes dryer. Since the bottom of the lowering is arranged on the bottom side below the maximum liquid filling level of the liquid basin arranged below the separating bottom, a bottom-side portion of the heat sink or the heat sink arranged in the recess can be arranged lower overall than would be possible with a conventional separating tray completely above a maximum Flüssigkeitsfüllhöhe a liquid pool of a clothes dryer would be arranged. When using the floor assembly according to the invention can thus be developed for the heat sink additional space within the liquid pool. In this way, a heat sink with a height that is greater than a height of a heat sink, which could be installed in the same tumble dryer without the floor assembly according to this embodiment, can be installed in a tumble dryer. This is also accompanied by an increase in the energy efficiency of a laundry dryer equipped with a floor assembly according to the invention. The possible size of the heat sink depends among other things on how far the bottom of the sink is located below the maximum liquid level of the liquid pool.
Die Absenkung muss nicht entsprechend der Vertiefung wasserdicht und wannenartig ausgebildet sein, da ein körperlicher Kontakt zwischen der Wärmesenke und einer in dem Flüssigkeitsbecken enthaltenen Flüssigkeit bzw. eine dadurch bedingte Abkühlung des Evaporators sich nicht negativ auf die Kühlleistung der Wärmesenke auswirkt. Zudem ist die relative Luftfeuchtigkeit in der Umgebung der Wärmesenke ohnehin relativ hoch, so dass eine Erhöhung der relativen Luftfeuchtigkeit in ihrer Umgebung durch die Anwesenheit der in dem Flüssigkeitsbecken vorhandenen Flüssigkeit nahezu ausgeschlossen werden kann. Jedoch kann die Absenkung alternativ entsprechend der Vertiefung wannenartig und wasserdicht ausgebildet sein.The lowering does not have to be formed in a watertight and trough-like manner according to the recess, since physical contact between the heat sink and a liquid contained in the liquid tank or consequent cooling of the evaporator does not adversely affect the cooling performance of the heat sink. In addition, the relative humidity in the vicinity of the heat sink anyway relatively high, so that an increase in the relative humidity in their environment by the presence of existing in the liquid pool liquid can be almost excluded. However, the lowering may alternatively be formed trough-like and waterproof according to the depression.
In vorteilhafter Weise ist an einer der Wärmesenke zugewandten Seite eines Bodens der Absenkung wenigstens ein weiteres Sicherungsmittel zum Sichern einer Positionierung der Wärmesenke relativ zu dem Boden der Absenkung angeordnet. Dies ist insbesondere bei einem Wäschetrockner in Form eines Trommeltrockners oder eines Waschtrockners wegen der im Betrieb eines Trommeltrockners bzw. Waschtrockners auftretenden Vibrationen von Vorteil. Mittels des weiteren Sicherungsmittels kann eine bestimmungsgemäße Positionierung des Abschnitts der Wärmesenke relativ zu dem Boden der Absenkung unter derartigen Belastungen zuverlässig gewährleistet werden, was die Robustheit eines entsprechend ausgestatteten Wäschetrockners verbessert und eine Geräuschbildung innerhalb des Wäschetrockners durch ein Aneinanderstoßen von nicht bestimmungsgemäß miteinander verbundenen Bauteilen verhindert. Mittels des Sicherungsmittels kann beispielsweise eine formschlüssige Verbindung zwischen dem Trennboden und der Wärmesenke hergestellt werden. Das Sicherungsmittel kann als geschlossene, im Wesentlichen senkrecht von dem Boden der Absenkung abstehende Wandung ausgebildet sein. Alternativ können mehrere separate Sicherungsmittel in Form von senkrecht von dem Boden der Absenkung abstehenden Vorsprüngen an dem Boden der Absenkung angeordnet sein.Advantageously, at least one further securing means for securing a positioning of the heat sink relative to the bottom of the lowering is arranged on a side of a bottom of the depression facing the heat sink. This is particularly advantageous in a tumble dryer in the form of a drum dryer or a washer dryer because of the vibrations occurring during operation of a drum dryer or washer dryer. By means of the further securing means, a proper positioning of the portion of the heat sink relative to the bottom of the reduction can be reliably ensured under such loads, which improves the robustness of a suitably equipped tumble dryer and prevents noise within the tumble dryer by abutting each other not intentionally interconnected components. By means of the securing means, for example, a positive connection between the separating tray and the heat sink can be produced. The securing means may be formed as a closed, substantially perpendicular from the bottom of the lowering projecting wall. Alternatively, a plurality of separate securing means in the form of protruding perpendicularly from the bottom of the lowering protrusions may be arranged at the bottom of the lowering.
Es wird des Weiteren als vorteilhaft erachtet, wenn der Boden der Absenkung tragend ausgebildet ist. Hierdurch kann die Wärmesenke auf den Boden der Absenkung aufgestellt und von diesem getragen und gehalten werden. Der Boden der Absenkung bzw. der Trennboden ist hierzu mit einer geeigneten Formstabilität zu versehen. Hierzu können an dem Boden der Absenkung, insbesondere bodenseitig, Verstärkungsrippen oder dergleichen angeordnet sein.It is further considered advantageous if the bottom of the sink is designed to be load-bearing. As a result, the heat sink can be placed on the floor of the lowering and carried and held by this. The bottom of the lowering or the separating tray is to be provided for this purpose with a suitable dimensional stability. For this purpose, reinforcing ribs or the like can be arranged on the bottom of the lowering, in particular on the bottom side.
Ferner wird vorgestellt, dass an dem Boden der Absenkung wenigstens eine Öffnung ausgebildet ist. Sollte es im Betrieb eines Wäschetrockners dazu kommen, dass die Wärmesenke zeitweilig teilweise in eine in dem Flüssigkeitsbecken enthaltene Flüssigkeit eintaucht, kann durch diese Ausgestaltung bei fallendem Flüssigkeitsfüllstand in dem Flüssigkeitsbecken eine auf dem Boden der Absenkung befindliche Flüssigkeit über die Öffnung wieder ablaufen und in das Flüssigkeitsbecken gelangen. In der Öffnung können Mittel vorgesehen sein, die nur ein Ablaufen der Flüssigkeit ermöglichen, jedoch verhindern, dass die Flüssigkeit in den Bereich oberhalb des Trennbodens gelangt. Wird die Öffnung relativ groß ausgebildet, kann zudem Umgebungsluft zwischen die Unterseite der Wärmesenke und die Oberseite des Bodens der Absenkung gelangen, wodurch diese Bereiche getrocknet werden können, was beispielsweise eine Geruchsbildung oder Schimmelbildung an diesen Komponenten eines Wäschetrockners verhindert.Furthermore, it is proposed that at least one opening is formed at the bottom of the depression. Should it happen during operation of a tumble dryer, that the heat sink temporarily partially immersed in a liquid contained in the liquid tank, this configuration at falling liquid level in the liquid tank, a liquid located on the bottom of the sink drain through the opening again and into the liquid pool reach. In the opening means may be provided, which allow only a drainage of the liquid, but prevent the liquid from entering the area above the separating bottom. If the opening is made relatively large, can also ambient air between the bottom of the Heat sink and the top of the bottom of the sink pass, whereby these areas can be dried, which for example prevents odor or mold on these components of a tumble dryer.
Bei einer besonders vorteilhaften Ausgestaltung der erfindungsgemäßen Bodengruppe ist vorgesehen, dass die Wärmequelle ein Kondensator und die Wärmesenke ein Evaporator für ein in der Wärmepumpe zirkulierendes Kältemittel sind.In a particularly advantageous embodiment of the floor assembly according to the invention, it is provided that the heat source is a condenser and the heat sink is an evaporator for a refrigerant circulating in the heat pump.
Die Erfindung schafft auch einen Wäschetrockner, welcher die erfindungsgemäße Bodengruppe oder eine ihrer beschriebenen Ausgestaltungen umfasst. Dieser Wäschetrockner ist entsprechend mit den oben zur erfindungsgemäßen Bodengruppe genannten Vorteilen verbunden. Die Bodengruppe kann in dem Wäschetrockner mit einem herkömmlichen Gehäuse oder mit einem speziell für diese Bodengruppe entworfenen und hergestellten Gehäuse kombiniert sein.The invention also provides a tumble dryer comprising the underbody of the invention or one of its described embodiments. This dryer is connected in accordance with the above mentioned floor covering groups of the invention. The underbody may be combined in the tumble dryer with a conventional housing or with a housing designed and manufactured specifically for that underbody.
