Description

Gebiet der ErfindungField of the invention

Die Erfindung betrifft einen Wäschebehandlungsschrank, wie z.B. einen Wäschetrocknungsschrank. Dabei handelt es sich um ein Gerät mit einem im Betrieb ruhenden, d.h. nicht rotierenden, Nutzraum, in welchen die Wäsche zur Behandlung eingebracht wird. Zudem besitzt das Gerät Mittel zur Wäschebehandlung, wie z.B. eine Trocknungsanlage oder eine Bedampfungsanlage. Schränke dieser Art dienen z.B. zum Trocknen von Wäsche, aber auch zum Auffrischen oder zur Geruchsbehandlung von Wäsche.The invention relates to a laundry treatment cabinet, such as e.g. a clothes drying cabinet. This is a device with a resting in operation, i. non-rotating, useful space in which the laundry is introduced for treatment. In addition, the device has means for laundry treatment, such as. a drying plant or a vaporization plant. Cabinets of this kind serve e.g. for drying laundry, but also for refreshing or for the odor treatment of laundry.

Hintergrundbackground

In EP 2 330 247 ist ein Schranktrockner für Wäsche beschrieben, in welchem die Prozessluft durch eine untere Lüftungsöffnung aus dem Nutzraum abgesogen und zum Trocknen und Aufheizen durch den Verdampfer und den Kondensator einer Wärmepumpenanordnung geführt wird. Sodann wird die Luft von Luftfördermitteln durch einen Verbindungskanal an der Rückseite des Geräts zu oberen Lüftungsöffnungen geführt, von wo die Luft wieder in den Nutzraum eingeführt wird. Die Wärmepumpenanordnung ist dabei in einem Sockelteil unterhalb des Nutzraums untergebracht.In EP 2 330 247 is described a cabinet dryer for laundry, in which the process air is sucked through a lower vent opening from the work space and is led to the drying and heating by the evaporator and the condenser of a heat pump assembly. thereupon The air is routed by air conveyors through a connecting channel on the back of the unit to upper vents, from where the air is reintroduced into the utility room. The heat pump assembly is housed in a base part below the utility room.

Darstellung der ErfindungPresentation of the invention

Es ist Aufgabe der vorliegenden Erfindung, einen Wäschebehandlungsschrank bereitzustellen, welcher verbesserte Wäschebehandlungseigenschaften aufweist.It is an object of the present invention to provide a laundry treatment cabinet having improved laundry treatment properties.

Diese Aufgabe wird vom Wäschebehandlungsschrank gemäss Anspruch 1 erfüllt. Demgemäss besitzt der Wäschebehandlungsschrank einen Nutzraum mit Belüftungsöffnungen zum Einblasen von Prozessluft in den Nutzraum. Mindestens ein Teil der Belüftungsöffnungen ist an der Decke des Nutzraums angeordnet, um einen von der Decke nach unten laufenden Luftstrom im Nutzraum zu erzeugen. Weiter sind Hilfsmittel zum Erzeugen eines schräg nach oben laufenden Luftstroms im Nutzraum vorgesehen. Somit wird ein von oben nach unten laufender Luftstrom mit einem schräg nach oben laufenden Luftstrom kombiniert. Es zeigt sich, dass die dadurch erzielte verbesserte Durchlüftung der Wäsche es unter anderem erlaubt, die Prozessdauer zu verkürzen, die Wäsche (im Rahmen eines Trocknungsprozesses) schneller zu trocknen und homogenere Resultate zu erzielen, z.B. bei der Bereitstellung "bügeltrockner" Wäsche. Die Reduktion der Prozessdauer führt zu einer Reduktion des Energieverbrauchs des Geräts.This object is met by the laundry treatment cabinet according to claim 1. Accordingly, the laundry treatment cabinet has a work space with ventilation openings for blowing process air into the work space. At least a portion of the ventilation openings is arranged on the ceiling of the work space in order to produce a downwardly running airflow in the work space from the ceiling. Next aids are provided for generating an obliquely upward flow of air in the useful space. Thus, a top-to-bottom airflow is combined with an upwardly-directed airflow. It can be seen that the resulting improved aeration of the laundry, among other things, makes it possible to shorten the process time, to dry the laundry faster (as part of a drying process) and to achieve more homogeneous results, e.g. in providing "ironing" laundry. The reduction of the process time leads to a reduction of the energy consumption of the device.

Unter einem "schräg nach oben laufenden Luftstrom" ist dabei ein Luftstrom zu verstehen, bei welchem der über alle Luftmoleküle gemittelte Geschwindigkeitsvektor schräg nach oben gerichtet ist, d.h. nach oben gerichtet ist aber nicht parallel zur Vertikalen verläuft.An "obliquely upwardly flowing airflow" is to be understood as meaning an airflow in which the velocity vector averaged over all air molecules is oriented obliquely upward, i. directed upward but not parallel to the vertical runs.

In einer bevorzugten Ausführung umfassen die erwähnten Hilfsmittel einen Ventilator mit schräg zur Vertikalen angeordneten Blasrichtung. Dieser saugt Prozessluft aus dem Nutzraum an und gibt diese in den schräg nach oben gerichteten Luftstrom wieder in den Nutzraum ab. Vorteilhaft ist der Ventilator direkt im Nutzraum angeordnet.In a preferred embodiment, the mentioned aids comprise a fan obliquely to Vertical arranged blowing direction. This sucks process air from the work space and returns it in the obliquely upward air flow back into the usable space. The fan is advantageously arranged directly in the utility room.

In einer anderen Ausführung weisen die Hilfsmittel Düsen auf, die in einer Seitenwand des Nutzraums angeordnet sind. Über diese Düsen wird Prozessluft von aussen in den schräg nach oben gerichteten Luftstrom eingeführt.In another embodiment, the tools have nozzles which are arranged in a side wall of the work space. Process air is introduced from the outside into the obliquely upward-directed air flow via these nozzles.

Es zeigt sich, dass eine besonders gute Luftdurchmischung erzielt werden kann, wenn die genannten Hilfsmittel im unteren Drittel des Nutzraums angeordnet sind.It turns out that a particularly good air mixing can be achieved if the said aids are arranged in the lower third of the working space.

Die Erfindung eignet sich besonders für einen Wäschebehandlungsschrank mit einem Dampfgenerator zum Einführen von Dampf, z.B. über den Verbindungskanal, in den Nutzraum oder mit einem Duftgenerator zum Einführen eines Duftstoffs in den Nutzraum, da in diesem Fall der Dampf bzw. der Duftstoffs homogen in die Wäsche eingetragen wird.The invention is particularly suitable for a laundry treatment cabinet with a steam generator for introducing steam, e.g. via the connecting channel, into the working space or with a fragrance generator for introducing a fragrance into the working space, since in this case the steam or the fragrance is introduced homogeneously into the laundry.

Die Rückseite ist die der Vorderseite gegenüber liegende Seite. Begriffe der Art "vor", "vorne", "hinter" und "hinten" beziehen sich auf dieses Bezugssystem, d.h. die Türe ist beispielsweise vor dem Nutzraum und der Nutzraum ist vor der Rückseite angeordnet.In the following, the side of the device is designated as the front side of the device, on which the door is arranged, via which the user has access to the work space. The back is the side opposite the front. Terms of the type "forward," "front," "rear," and "rear" refer to this frame of reference, i. For example, the door is in front of the utility room and the utility room is located in front of the back.

Der Begriff "seitlich" bezieht sich auf eine horizontale Richtung senkrecht zur Richtung zwischen vorne und hinten. Beispielsweise ist der Verbindungskanal seitlich einer Seitenwand des Nutzraums angeordnet, d.h. in horizontaler Blickrichtung parallel zur Vorderseite überlappen sich die Seitenwand des Nutzraums und der Verbindungskanal.The term "lateral" refers to a horizontal direction perpendicular to the direction between front and back. For example, the connection channel is arranged laterally of a side wall of the work space, i. in horizontal direction parallel to the front side, the side wall of the work space and the connecting channel overlap.

Begriffe wie "oben", "oberhalb", "unter" und "unterhalb" beziehen sich, wie bereits erwähnt, auf das Gerät bei bestimmungsgemässer Montage, in welcher sich der Sockelteil unterhalb des Nutzraums befindet und die Stange zur Aufnahme von Kleiderbügel in einem oberen Ende des Nutzraums befestigt ist. Ebenso beziehen sich Begriffe wie "horizontal" und "vertikal" auf diese bestimmungsgemässe Montage, d.h. die Bodenwand des Nutzraums, welche den Nutzraum vom Sockelteil trennt, ist z.B. im Wesentlichen horizontal angeordnet, während die ungefähr senkrecht zur Bodenwand stehenden Seitenwände, die Rückwand und die Türe des Nutzraums im Wesentlichen vertikal angeordnet sind.Terms such as "above", "above", "below" and "below" refer, as already mentioned, to the device when installed as intended, in which the base part is located below the work space and the rod for holding hangers in an upper End of the work space is attached. Likewise, terms such as "horizontal" and "vertical" refer to this intended assembly, ie, the bottom wall of the work space, which separates the work space from the base part, for example, arranged substantially horizontally, while the approximately perpendicular to the bottom wall side walls, the rear wall and the door of the work space are arranged substantially vertically.

Eine vorteilhafte Ausführung des Wäschebehandlungsschranks wird in Fig. 1 - 3 gezeigt, wobei wichtige funktionelle Komponenten noch einmal isoliert in Fig. 4 dargestellt sind.An advantageous embodiment of the laundry treatment cabinet is in Fig. 1-3 shown, with important functional components once again isolated in Fig. 4 are shown.

Wie ersichtlich, besitzt der Wäschebehandlungsschrank 10 ein im Wesentlichen quaderförmiges Gehäuse 11 mit einem Nutzraum 12, welcher ebenfalls im Wesentlichen Quaderform aufweist. Unterhalb des Nutzraums 12 schliesst sich ein Sockelteil 13 an. Seitlich am Gerät und auch seitlich des Nutzraums 12 ist ein im Wesentlichen vertikaler Schacht 14 vorgesehen (im vorliegenden Text auch als Verbindungskanal bezeichnet). Oberhalb des Nutzraums 12 befindet sich ein Oberteil bzw. Deckenraum 15.As can be seen, the laundry treatment cabinet 10 has a substantially cuboidal housing 11 with a work space 12, which also has a substantially cuboid shape. Below the working space 12, a base part 13 connects. The side of the device and also the side of the work space 12, a substantially vertical shaft 14 is provided (also referred to in the text as a connecting channel). Above the work space 12 is a top or ceiling space 15th

Der Schrank 10 wird nach hinten von einer Rückwand 16, seitlich von Seitenwänden 17, 18, nach oben von einer Decke 19, nach unten von einem Boden 20 und nach vorne von einer Tür 21 zum Befüllen des Nutzraums 12 begrenzt. Der Nutzraum 12 dient der Aufnahme der Wäsche. Hierzu sind im Nutzraum geeignete Mittel zur Wäscheaufnahme vorgesehen, so z.B. eine Stange 23 zur Aufnahme von Kleiderbügeln sowie gegebenenfalls weitere Mittel zur Wäscheaufnahme, wie Körbe, Gitter, etc. Für den Benutzer ist der Nutzraum 12 über die Tür 21 zugänglich.The cabinet 10 is bounded to the rear by a rear wall 16, laterally by side walls 17, 18, upwardly by a ceiling 19, downwardly by a floor 20 and forwardly by a door 21 for filling the work space 12. The work space 12 is used to hold the laundry. For this purpose, suitable means for receiving laundry are provided in the work space, e.g. a rod 23 for receiving hangers and optionally other means for laundry reception, such as baskets, grilles, etc. For the user, the useful space 12 is accessible via the door 21.

Im Sockelteil 13 ist eine Wärmepumpenanordnung 22 umfassend einen Kompressor 30, einen Kondensator 31, einen Zusatzwärmetauscher 32, ein Expansionsventil 33 und einen Verdampfer 34 vorgesehen. Mit dem Kompressor 30 wird in bekannter Weise ein Medium durch den Kondensator 31, den Zusatzwärmetauscher 32, das Expansionsventil 33, den Verdampfer 34 und zurück zum Kompressor 30 geführt, wodurch der Kondensator 31 erwärmt und der Verdampfer 34 gekühlt wird. Der Zusatzwärmetauscher 32 dient in der in EP 2 034 084 beschriebenen Weise dazu, dem System Wärme zu entziehen. Hierzu ist ein Lüfter 35 vorgesehen, der Kühlluft aus der Umgebung durch den Zusatzwärmetauscher 32 und über das Expansionsventil 33 und den Kompressor 30 bläst.In the base part 13, a heat pump assembly 22 comprising a compressor 30, a condenser 31, an additional heat exchanger 32, an expansion valve 33 and an evaporator 34 is provided. With the compressor 30, a medium is passed in a known manner through the condenser 31, the additional heat exchanger 32, the expansion valve 33, the evaporator 34 and back to the compressor 30, whereby the condenser 31 is heated and the evaporator 34 is cooled. The additional heat exchanger 32 is used in the in EP 2 034 084 described manner to deprive the system heat. For this purpose, a fan 35 is provided which Cooling air blows from the environment through the additional heat exchanger 32 and via the expansion valve 33 and the compressor 30.

Weiter ist im Sockelteil 13 ein Dampfgenerator 36 vorgesehen, mit welchem Dampf erzeugt werden kann. Wie beispielsweise in EP 2 330 247 beschrieben, kann der Dampf im Normalbetrieb des Wäschebehandlungsschranks 10 dazu verwendet werden, die Wäsche aufzufrischen und/oder zu entknittern. Der Dampfgenerator 36 ist durch einen Kanal 37 über eine Eintrittsöffnung 39, im Folgenden auch als "Ausgang" des Dampfgenerators bezeichnet wird, mit dem Schacht 14 verbunden. Im gezeigten Beispiel ist die Eintrittsöffnung 39 in der Nähe des unteren Endes des Schachts 14 angeordnet.Further, in the base part 13, a steam generator 36 is provided, with which steam can be generated. Such as in EP 2 330 247 During normal operation of the laundry treatment cabinet 10, the steam may be used to refresh and / or wrinkle the laundry. The steam generator 36 is connected to the shaft 14 through a channel 37 via an inlet opening 39, hereinafter also referred to as the "outlet" of the steam generator. In the example shown, the inlet opening 39 is arranged in the vicinity of the lower end of the shaft 14.

Im Sockelteil 13 sind ebenfalls noch ein Behälter mit zwei Tanks (nicht gezeigt) angeordnet, die herausnehmbar Tank sind. Einer dieser Tanks bildet einen Frischwassertank für den Dampfgenerator 36, und der andere einen Kondenswassertank für Wasser, das aus einer Wanne im Boden des Sockelteils 13 gepumpt wird.In the base part 13, a container with two tanks (not shown) are also still arranged, which are removable tank. One of these tanks forms a fresh water tank for the steam generator 36, and the other a condensed water tank for water, which is pumped from a trough in the bottom of the base part 13.

An der Decke 41 des Nutzraums 12 sind Belüftungsöffnungen 42 vorgesehen, mit denen im Nutzraum 12 ein von oben nach unten verlaufender Luftstrom 43 erzeugt werden kann. Die so in den Nutzraum 12 eingebrachte Luft verlässt diesen wieder über eine Abzugsöffnung 44 im Boden 45 des Nutzraums.On the ceiling 41 of the work space 12 ventilation openings 42 are provided with which in the useful space 12, a top-down running airflow 43 can be generated. The air thus introduced into the work space 12 leaves it again via a discharge opening 44 in the bottom 45 of the work space.

Unterhalb der Abzugsöffnung 44 schliesst sich ein im Sockelteil 13 angeordneter Kanal 46 an. Der Kanal 46 ist Teil des Zirkulationssystems, durch welches die Luft zur Aufbereitung geführt wird.Below the outlet opening 44, a channel 46 arranged in the base part 13 adjoins. The channel 46 is part of the circulation system, through which the air is led to the treatment.

Im ersten, sich verjüngenden Kanalabschnitt des Kanals 46 sind in üblicher Weise austauschbare Filter 47, 48 angeordnet, um Verschmutzungen von den Wärmetauschern des Verdampfers 34 und des Kondensators 31 fernzuhalten.In the first, tapered channel portion of the channel 46 are interchangeable filters 47, 48 arranged in the usual manner to keep contaminants from the heat exchangers of the evaporator 34 and the capacitor 31.

Der Verdampfer 34 und der Kondensator 31 sind in einem anschliessenden zweiten Kanalabschnitt des Kanals 46 angeordnet. Der Kanal 46 leitet in diesem Abschnitt die Luft durch die Wärmetauscher des Verdampfers 34 und des Kondensators 31.The evaporator 34 and the condenser 31 are in a subsequent second channel section of the channel 46 arranged. The duct 46, in this section, passes the air through the heat exchangers of the evaporator 34 and the condenser 31.

In Luftflussrichtung nach dem Kondensator 31 schliesst sich ein dritter Kanalabschnitt des Kanals 46 an, welcher nach einer weiteren Verjüngung im Ansaugbereich eines Radiallüfters 50 mündet, der das Luftfördermittel zum Fördern der Prozessluft bildet.In the direction of air flow downstream of the condenser 31, a third channel section of the channel 46 adjoins, which opens into the suction region of a radial fan 50 after further tapering, which forms the air conveying means for conveying the process air.

Der Radiallüfter 50 ist im seitlichen Schacht 14 des Wäschebehandlungsschranks 10 angeordnet. Die Luft wird vom Radiallüfter 50 durch den vertikal verlaufenden Schacht 14 geleitet, in welchem sie zum Deckenraum 15 des Geräts aufsteigen kann.The radial fan 50 is arranged in the lateral shaft 14 of the laundry treatment cabinet 10. The air is directed by the radial fan 50 through the vertical shaft 14, in which it can ascend to the ceiling space 15 of the device.

Im Schacht 14 selbst sind eine Lichtquelle 51 und mindestens eine Katalysatorfläche 52 zur photokatalytischen Luftbehandlung angeordnet. Haushaltsgeräte mit solchen Katalysatoren sind beispielsweise aus EP 2241826 A1 bekannt.In the shaft 14 itself, a light source 51 and at least one catalyst surface 52 are arranged for the photocatalytic air treatment. Household appliances with such catalysts are made, for example EP 2241826 A1 known.

Oberhalb der Lichtquelle 51 ist im Schacht 14 eine Heizung 53 angeordnet, mit welcher die im Gerät 10 zirkulierende Luft bei Bedarf erwärmt werden kann.Above the light source 51, a heater 53 is arranged in the shaft 14, with which the air circulating in the device 10 can be heated if necessary.

An seinem oberen Ende geht der Verbindungskanal 14 in einen horizontal verlaufenden Deckenkanal 55 über, welcher oberhalb des Nutzraums 12 angeordnet ist. Die Belüftungsöffnungen 42 sind mit diesem Deckenkanal verbunden, so dass, wie bereits beschrieben, die Luft vom Deckenkanal 55 von oben in den Nutzraum 12 strömen kann. Der Weg, den die Luft wie beschrieben durch den Wäschebehandlungsschrank 10 nimmt, bildet den Hauptteil eines Zirkulationssystems, wobei auf die Darstellung weiterer Teile des Zirkulationssystems, wie allfällige Ansaug- und Abluftöffnungen, der besseren Übersicht wegen verzichtet wird.At its upper end, the connecting channel 14 merges into a horizontally extending ceiling channel 55, which is arranged above the useful space 12. The ventilation openings 42 are connected to this ceiling channel, so that, as already described, the air from the ceiling channel 55 can flow from above into the working space 12. The path taken by the air as described by the laundry treatment cabinet 10, forms the main part of a circulation system, wherein the representation of other parts of the circulation system, such as any intake and exhaust ports, is omitted for the sake of clarity.

Weiter weist der Trockenschrank 10 eine ebenfalls nicht weiter dargestellte Bedienkonsole mit Ein- und Ausgabemitteln auf, die zur Steuerung bzw. Überwachung des Wäschebehandlungsschranks dient. Die Ein- und/oder Ausgabemittel sind mit einer Gerätesteuerung 56 (Fig. 4) verbunden, welche die Operation der verschiedenen Komponenten des Geräts steuert.Next, the drying cabinet 10 on a likewise not shown control panel with input and output means, which serves to control or monitoring of the laundry treatment cabinet.

Im Nutzraum 12 sind weiter die oben erwähnten Hilfsmittel 60 angeordnet, mit denen der schräg nach oben laufende Luftstrom 61 erzeugt wird. Diese Hilfsmittel 60 sind vorteilhaft an einer vertikalen Seitenwand 65 des Nutzraums 12 befestigt.In the work space 12, the above-mentioned aids 60 are further arranged, with which the obliquely upward current air flow 61 is generated. These aids 60 are advantageously attached to a vertical side wall 65 of the work space 12.

Die vertikalen Seitenwand 65, an welcher die Hilfsmittel 60 befestigt sind, ist vorteilhaft parallel zur Stange 23 angeordnet, so dass der mittlere Geschwindigkeitsvektor des Luftstroms 61 in einer Ebene senkrecht zur Stange 23 liegt. Auf diese Weise werden an der Stange 23 mit Kleiderbügeln aufgehängte Wäschestücke optimal durchlüftet.The vertical side wall 65, to which the aids 60 are fastened, is advantageously arranged parallel to the rod 23, so that the mean velocity vector of the air flow 61 lies in a plane perpendicular to the rod 23. In this way, laundry items hung on the bar 23 with hangers are optimally ventilated.

In der dargestellten Ausführung umfassen die Hilfsmittel 60 einen Ventilator 62, der in einer Halterung 63 befestigt ist. Die Blasrichtung des Ventilators ist schräg zur Vertikalen angeordnet, unter einem Winkel α. Dieser Winkel beträgt vorteilhaft ca. 45° ± 15°.In the illustrated embodiment, the tools 60 include a fan 62 mounted in a bracket 63. The blowing direction of the fan is arranged obliquely to the vertical, at an angle α. This angle is advantageously about 45 ° ± 15 °.

Um eine möglichst gute Luftdurchmischung zu erreichen, sollten sich zumindest 75 % des von den Hilfsmitteln 60 erzeugten Luftstroms in einem Winkelbereich zwischen 30° und 60° relativ zur vertikalen Richtung schräg nach oben bewegen.In order to achieve the best possible air mixing, at least 75% of the air flow generated by the tools 60 should move obliquely upward in an angular range between 30 ° and 60 ° relative to the vertical direction.

Eine zweite Ausführung des Wäschebehandlungsschranks ist in Fig. 5 dargestellt. In dieser Ausführung werden die erwähnten Hilfsmittel 60 von Düsen 70 gebildet, welche mit dem Schacht 14 verbunden sind und einen Teil der im Schacht 14 aufsteigenden Prozessluft in den Nutzraum 12 ableiten. Auch auf diese Weise kann im Nutzraum 12 der schräg nach oben laufender Luftstrom 61 erzeugt werden.A second embodiment of the laundry treatment cabinet is in Fig. 5 shown. In this embodiment, the aforementioned tools 60 are formed by nozzles 70, which are connected to the shaft 14 and divert a portion of the ascending process air in the shaft 14 into the work space 12. Also in this way, the obliquely upward-running airflow 61 can be generated in the working space 12.

In den soweit dargestellten Ausführungen der Erfindung ist zur Bedampfung von Wäsche ein Dampfgenerator 36 vorgesehen, welcher Dampf in das Zirkulationssystem der Prozessluft einführt. Alternativ kann der Dampf auch direkt in den Nutzraum 12 eingeführt werden.In the embodiments of the invention shown so far, a steam generator 36 is provided for steaming laundry, which steam into the circulation system the process air introduces. Alternatively, the steam can also be introduced directly into the work space 12.

Zusätzlich oder alternativ zum Dampfgenerator kann auch ein Duftgenerator vorgesehen sein, der einen Duftstoff in die Prozessluft einführt. Vorzugsweise wird dieser Duftstoff in den Nutzraum eingeführt.In addition or as an alternative to the steam generator, it is also possible to provide a fragrance generator which introduces a fragrance into the process air. Preferably, this perfume is introduced into the work space.
