Description

Die Erfindung betrifft eine Bodengruppe für ein Gerät zum Trocknen von Wäsche, aufweisend einen Trennboden und zumindest mittelbar auf den Trennboden aufstellbare Wärmetauscher einer thermisch an ein Prozessluftsystem des Geräts gekoppelten Wärmepumpe, wobei die Wärmetauscher eine unterschiedliche Bauhöhe aufweisen. Des Weiteren betrifft die Erfindung ein Gerät zum Trocknen von Wäsche.The invention relates to a floor assembly for a device for drying laundry, having a dividing floor and heat exchangers of a heat pump thermally coupled to a process air system of the device, which heat exchangers can be set up at least indirectly on the separating floor, the heat exchangers having different overall heights. The invention also relates to a device for drying laundry.

Geräte zum Trocknen von Wäsche sind in vielfältigen Ausgestaltungen bekannt. Insbesondere sind Geräte zum Trocknen von Wäsche bekannt, die ein geschlossenes Prozessluftsystem mit einer zu trocknende Wäsche aufnehmenden Trockenkammer und eine thermisch an das Prozessluftsystem gekoppelte Wärmepumpe zur Rückgewinnung von Wärme aus der in dem Prozessluftsystem zirkulierenden Prozessluft aufweisen. Die Wärmepumpe bildet dabei einen Bestandteil einer bodenseitig unterhalb der Trockenkammer befindlichen Bodengruppe des Geräts, durch die ein Abschnitt des Prozessluftsystems verläuft.Devices for drying laundry are known in a variety of configurations. In particular, devices for drying laundry are known which have a closed process air system with a drying chamber receiving laundry to be dried and a heat pump thermally coupled to the process air system for recovering heat from the process air circulating in the process air system. The heat pump forms part of a floor assembly of the device which is located on the floor below the drying chamber and through which a section of the process air system runs.

Die Wärmepumpe weist zwei thermisch an das Prozessluftsystem gekoppelte Wärmetauscher auf, nämlich einen die aus der Trockenkammer austretende Prozessluft abkühlenden und entfeuchtenden Wärmetauscher (Verdampfer) und einen die der Trockenkammer zuzuführenden Prozessluft erwärmenden Wärmetauscher (Verflüssiger). An dem Verdampfer kondensiert ein Teil der in der Prozessluft enthaltenen Feuchtigkeit. Das dabei gebildete Kondensat fließt unter Schwerkraftwirkung von dem Verdampfer ab und wird in einer geodätisch tiefer als der Verdampfer angeordneten Kondensatwanne der Bodengruppe aufgefangen bzw. gesammelt. Die Wärmetauscher der Wärmepumpe sind oberhalb der Kondensatwanne angeordnet, um nicht in Kontakt mit dem in der Kondensatwanne vorhandenen Kondensat zu kommen. Hierzu ist oberhalb der Kondensatwanne ein Trennboden angeordnet, auf dem die Wärmetauscher aufstehen bzw. der die Wärmetauscher trägt. Der Bauraum unterhalb der Wärmetauscher bzw. des Trennbodens ist durch die Kondensatwanne begrenzt.The heat pump has two heat exchangers thermally coupled to the process air system, namely a heat exchanger (evaporator) that cools and dehumidifies the process air exiting the drying chamber and a heat exchanger (condenser) that heats the process air to be supplied to the drying chamber. Some of the moisture contained in the process air condenses on the evaporator. The condensate formed in the process flows away from the evaporator under the action of gravity and is caught or collected in a condensate pan of the floor pan which is arranged geodetically deeper than the evaporator. The heat exchangers of the heat pump are arranged above the condensate pan in order not to come into contact with the condensate present in the condensate pan. For this purpose, a partition is arranged above the condensate pan, on which the heat exchangers stand or which carries the heat exchangers. The installation space below the heat exchanger or the partition is limited by the condensate pan.

Die Wärmepumpe enthält ein Kältemittel, welches in einem in sich geschlossenen Kreislauf zirkuliert und dabei zyklisch unter Aufnahme von Wärme verdampft und unter Abgabe von Wärme kondensiert wird. Das Verdampfen des Kältemittels geschieht überwiegend in dem Verdampfer der Wärmepumpe. Dem Verdampfer fließt das Kältemittel als Gemisch aus Flüssigkeit und Gas zu. Als Gas gelangt das Kältemittel dann zu einem Kompressor der Wärmepumpe, in dem es komprimiert wird. Der Kompressor ist auch der Antrieb, der das Kältemittel durch den geschlossenen Kreislauf treibt. Vom Kompressor gelangt das komprimierte Kältemittel zu dem Verflüssiger der Wärmepumpe, in dem es unter Abgabe von Wärme verflüssigt wird. Aus dem Verflüssiger gelangt das verflüssigte Kältemittel in ein Entspannungsorgan, insbesondere ein Ventil, eine Blende oder eine Kapillare, in dem der Binnendruck des Kältemittels herabgesetzt wird und in dem das Kältemittel schon teilweise wieder in Gas umgewandelt wird. Das so entstandene Gemisch aus Flüssigkeit und Gas gelangt wieder zu dem Verdampfer.The heat pump contains a refrigerant which circulates in a closed circuit and cyclically evaporates while absorbing heat and releasing it is condensed by heat. The evaporation of the refrigerant takes place predominantly in the evaporator of the heat pump. The refrigerant flows into the evaporator as a mixture of liquid and gas. The refrigerant then reaches a compressor of the heat pump as a gas, where it is compressed. The compressor is also the drive that drives the refrigerant through the closed circuit. The compressed refrigerant arrives from the compressor to the condenser of the heat pump, in which it is liquefied while releasing heat. From the liquefier, the liquefied refrigerant passes into an expansion device, in particular a valve, a diaphragm or a capillary, in which the internal pressure of the refrigerant is reduced and in which the refrigerant is already partially converted back into gas. The resulting mixture of liquid and gas is returned to the evaporator.

Die Energieeffizienz eines Wäschetrockners mit Wärmepumpe steigt mit dem Volumen der in der Wärmepumpe verwendeten Wärmetauscher, also dem Volumen des Verdampfers und des Verflüssigers. Für die Anordnung der Wärmetauscher der Wärmepumpe steht jedoch ein begrenzter Bauraum innerhalb einer Bodengruppe zur Verfügung, der durch an die Bodengruppe angrenzende Bauteile, beispielsweise durch die Trockenkammer, einen eine Wäschetrommel antreibenden Riemen oder ein Selbstreinigungssystem zum Reinigen eines Wärmetauschers der Wärmepumpe, eingeschränkt ist. Zur Steigerung der Energieeffizienz werden immer neue Varianten von Wärmepumpen entwickelt, die sich insbesondere durch die Größen bzw. Bauhöhen der Wärmetauscher voneinander unterscheiden können. Insbesondere kann der Verflüssiger einer Wärmepumpe ein größeres Volumen als der Verdampfer der Wärmepumpe aufweisen.The energy efficiency of a tumble dryer with a heat pump increases with the volume of the heat exchangers used in the heat pump, i.e. the volume of the evaporator and the condenser. For the arrangement of the heat exchangers of the heat pump, however, a limited installation space is available within a floor assembly, which is restricted by components adjoining the floor assembly, for example by the drying chamber, a belt driving a laundry drum or a self-cleaning system for cleaning a heat exchanger of the heat pump. In order to increase energy efficiency, new variants of heat pumps are constantly being developed, which can differ from one another in particular in terms of the size and height of the heat exchangers. In particular, the condenser of a heat pump can have a larger volume than the evaporator of the heat pump.

An dem Trennboden ist eine wannenartige, wasserdichte und zu dem Verflüssiger hin offen ausgebildete Vertiefung ausgebildet, wobei ein Boden der Vertiefung vollständig unterhalb einer maximalen Flüssigkeitsfüllhöhe einer bodenseitig unterhalb des Trennbodens angeordneten Kondensatwanne liegt und der Verflüssiger auf dem Boden aufsteht. Durch diese Ausgestaltung des Trennbodens wird der Bauraum für den Verflüssiger vergrößert, so dass zur Steigerung der Effizienz des Wäschetrockners ein Verflüssiger mit einem größeren Volumen verbaut werden kann.

A trough-like, watertight recess is formed on the separating base and is open towards the condenser, with a base of the recess lying completely below a maximum liquid filling height of a condensate tray arranged on the bottom underneath the separating base and the condenser standing on the base. This configuration of the partition floor increases the installation space for the condenser, so that a condenser with a larger volume can be built in to increase the efficiency of the tumble dryer.

Insbesondere können bzw. kann der Trennboden und/oder das Adapterbauteil teilweise oder vollständig aus einem Kunststoff hergestellt sein.Heat pumps are adapted, the heat exchangers of which have the same height, these heat exchangers then both stand up directly on the partition. In the context of the invention, an overall height of a heat exchanger is understood to mean a height of the heat exchanger in the direction of a device vertical axis, that is to say a vertical dimensioning of the heat exchanger. The adapter component supports the lower-height heat exchanger on the bottom side of the partition, so that the lower-height heat exchanger rests on the adapter component and the assembly formed from the lower-height heat exchanger and the adapter component stands on the partition. The partition base and / or the adapter component can or can be designed as an injection-molded component. In particular, the partition base and / or the adapter component can be made partially or completely from a plastic.

Die Wärmepumpe kann über die Wärmetauscher (Verdampfer, Verflüssiger) thermisch an das Prozessluftsystem des Geräts gekoppelt werden. Die Wärmepumpe kann als Kompressor-Wärmepumpe ausgebildet sein und entsprechend wenigstens einen Kompressor zum Verdichten des Kältemittels der Wärmepumpe und wenigstens eine Expansionseinheit zum Expandieren des Kältemittels aufweisen. Der Verdampfer entzieht der aus der Trockenkammer abgeführten Prozessluft Wärme (Wärmesenke für die Prozessluft), während Kältemittel innerhalb des Verdampfers verdampft wird. Der Verflüssiger führt der der Trockenkammer zuzuführenden Prozessluft Wärme zu (Wärmequelle für die Prozessluft), während Kältemittel innerhalb des Verflüssigers verflüssigt wird. Der Wärmetauscher mit geringerer Bauhöhe kann der Verdampfer sein, während der Wärmetauscher mit der größeren Bauhöhe der Verflüssiger sein kann.The heat pump can be thermally coupled to the process air system of the device via the heat exchanger (evaporator, condenser). The heat pump can be designed as a compressor heat pump and accordingly have at least one compressor for compressing the refrigerant of the heat pump and at least one expansion unit for expanding the refrigerant. The evaporator extracts heat from the process air discharged from the drying chamber (heat sink for the process air), while refrigerant is evaporated within the evaporator. The condenser supplies heat to the process air to be supplied to the drying chamber (heat source for the process air), while refrigerant is liquefied within the condenser. The heat exchanger with the lower overall height can be the evaporator, while the heat exchanger with the greater overall height can be the condenser.

Gemäß der Erfindung sind der Trennboden und das Adapterbauteil derart ausgebildet und relativ zueinander angeordnet, dass Oberseiten der Wärmetauscher in einer gemeinsamen horizontalen Ebene liegen. Hierdurch kann ein oberer Bauraum der Bodengruppe durch eine Belegung mit den Wärmetauschern stets optimal und gleichermaßen ausgenutzt werden. Dies macht eine einheitliche Verwendung eines die Wärmepumpe aufnehmenden Gehäuses der Bodengruppe möglich, ohne dass bauliche Änderungen an dem Gehäuse vorgenommen werden müssen. Hierdurch werden die Herstellungskosten der Baugruppe und entsprechend ausgestatteter Geräte mit unterschiedlich ausgebildeten Wärmepumpen reduziert.According to the invention, the partition base and the adapter component are designed and arranged relative to one another in such a way that the upper sides of the heat exchangers lie in a common horizontal plane. As a result, an upper installation space of the floor pan can always be optimally and equally used by occupying it with the heat exchangers. This makes uniform use of a housing of the floor pan that accommodates the heat pump possible without structural changes having to be made to the housing. This reduces the manufacturing costs of the assembly and correspondingly equipped devices with differently designed heat pumps.

Eine weitere vorteilhafte Ausgestaltung sieht vor, dass das Adapterbauteil zerstörungsfrei lösbar mit dem Trennboden verbunden ist. Hierdurch kann das Adapterbauteil auf einfache Art und Weise, vorzugsweise ohne Verwendung eines Werkzeugs, an dem Trennboden angeordnet und von diesem entfernt werden. Der Trennboden und das Adapterbauteil bilden einen losen Bauteilverbund. Der Trennboden und das Adapterbauteil sind dabei nicht über ein zusätzliches mechanisches Mittel, wie beispielsweise eine Schraubverbindung oder eine Nietverbindung, miteinander verbunden. Jedoch kann das Adapterbauteil beispielsweise über wenigstens einen zerstörungsfrei lösbaren Klemmmechanismus oder Rastmechanismus an dem Trennboden gesichert sein.A further advantageous embodiment provides that the adapter component is detachably connected to the partition in a non-destructive manner. As a result, the adapter component can be arranged on and removed from the partition base in a simple manner, preferably without the use of a tool. The partition and the adapter component form a loose component assembly. The partition base and the adapter component are not connected to one another via an additional mechanical means, such as a screw connection or a rivet connection. However, the adapter component can be secured to the partition base, for example, by means of at least one nondestructively releasable clamping mechanism or latching mechanism.

Nach einer weiteren vorteilhaften Ausgestaltung sind an einer den Wärmetauschern zugewandten Seite des Trennbodens Ausnehmungen ausgebildet und sind an einer dem Trennboden zugewandten Seite des Wärmetauschers mit größerer Bauhöhe und des Adapterbauteils jeweils Vorsprünge angeordnet, die formschlüssig in die Ausnehmungen an dem Trennboden eingefügt sind. Die Vorsprünge des Wärmetauschers mit größerer Bauhöhe und des Adapterbauteils können auf einfache Art und Weise in die jeweiligen Ausnehmungen des Trennbodens eingesteckt werden, um einem Formschluss zwischen einerseits dem Wärmetauscher mit größerer Bauhöhe und dem Adapterbauteil und andererseits dem Trennboden herzustellen. Hierdurch kann eine exakte Positionierung des Wärmetauschers mit größerer Bauhöhe und des Adapterbauteils an dem Trennboden dauerhaft sichergestellt werden. Zudem kann durch den jeweiligen Formschluss eine fehlerhafte Positionierung des Wärmetauschers mit größerer Bauhöhe und des Adapterbauteils relativ zu dem Trennboden verhindert werden, indem die Ausnehmungen und Vorsprünge derart ausgebildet sind, dass der jeweilige Formschluss nur bei einer bestimmten Relativstellung herstellbar ist. An dem Wärmetauscher mit größerer Bauhöhe und dem Adapterbauteil können jeweils zwei, drei oder vier entsprechende Vorsprünge angeordnet sein.According to a further advantageous embodiment, recesses are formed on a side of the partition plate facing the heat exchangers and projections are arranged on a side of the heat exchanger facing the partition base and of the adapter component, which are positively inserted into the recesses on the partition base. The projections of the heat exchanger with greater overall height and the adapter component can be easily inserted into the respective recesses of the partition in order to establish a positive fit between the heat exchanger with greater overall height and the adapter component on the one hand and the partition base on the other. In this way, exact positioning of the heat exchanger with a greater overall height and of the adapter component on the partition floor can be permanently ensured. In addition, incorrect positioning of the heat exchanger with greater structural height and the adapter component relative to the partition floor can be prevented by the respective form fit, in that the recesses and projections are designed in such a way that the respective form fit can only be produced in a certain relative position. Two, three or four corresponding projections can be arranged on the heat exchanger with a greater overall height and on the adapter component.

Vorteilhafterweise ist eine Anzahl der Ausnehmungen des Trennbodens größer als eine Anzahl von Vorsprüngen des Wärmetauschers mit größerer Bauhöhe und des Adapterbauteils und sind die Ausnehmungen derart an dem Trennboden ausgebildet, dass der Wärmetauscher mit größerer Bauhöhe und/oder das Adapterbauteil in verschiedenen Relativstellungen zu dem Trennboden formschlüssig mit dem Trennboden verbindbar sind bzw. ist. Hierdurch können bzw. kann der jeweilige Wärmetauscher mit größerer Bauhöhe und/oder das Adapterbauteil je nach baulicher Ausgestaltung der Wärmetauscher der Wärmepumpe optimal relativ zu dem Trennboden positioniert werden, so dass verschiedene Varianten der Dimensionierungen der Wärmetauscher der Wärmepumpe auf einfache Art und Weise konstruktiv aufgefangen werden können. Weitestgehend unabhängig von den baulichen Ausgestaltungen der Wärmetauscher der Wärmepumpe können bzw. kann der Wärmetauscher mit größerer Bauhöhe und/oder das Adapterbauteil zuverlässig und dauerhaft formschlüssig mit dem Trennboden verbunden werden.Advantageously, a number of the recesses of the dividing base is greater than a number of projections of the heat exchanger with a greater overall height and the adapter component and the recesses are formed on the dividing base in such a way that the heat exchanger with a greater overall height and / or the adapter component form-fit in different positions relative to the dividing base can be connected to the partition or is. As a result, the respective heat exchanger with a greater overall height and / or the adapter component, depending on the structural design of the heat exchangers of the heat pump, can be optimally positioned relative to the partition, so that different variants of the dimensions of the heat exchangers of the heat pump can be structurally accommodated in a simple manner can. Largely independent of the structural configurations of the heat exchangers of the heat pump, the heat exchanger with a greater overall height and / or the adapter component can be reliably and permanently positively connected to the partition.

Eine weitere vorteilhafte Ausgestaltung sieht vor, dass wenigstens eine Ausnehmung schlitzförmig ausgebildet ist. Die jeweiligen Vorsprünge sind demnach schwertartig ausgebildet, um formschlüssig in die schlitzförmigen Ausnehmungen eingefügt werden zu können. An dem jeweiligen Wärmetauscher kann beispielsweise an jeder Ecke ein in Höhenrichtung verlaufender Flansch angeordnet sein, dessen eines Ende auf der dem Trennboden zugewandten Seite des Wärmetauschers hervorsteht, um in die jeweilige Ausnehmung eingefügt werden zu können.
