Description
Hausgerät mit einem Strahler zum Erzeugen eines ultravioletten Domestic appliance with a radiator to produce an ultraviolet
Lichteslight
Die Erfindung betrifft ein Hausgerät mit einer Kammer, welche eingerichtet ist zum Behandeln eines Gutes mit einer Flüssigkeit und einen Sumpfbereich aufweist, an den eine Pumpeinrichtung zum Abpumpen von Flüssigkeit aus der Kammer angeschlossen ist, und einem Strahler zum Erzeugen eines ultravioletten Lichtes.The invention relates to a domestic appliance having a chamber which is adapted for treating a product with a liquid and a sump region, to which a pumping device for pumping liquid out of the chamber is connected, and a radiator for generating an ultraviolet light.
Ein solches Hausgerät geht aus der DE 43 42 049 C2 hervor. Das beschriebene Hausgerät ist eine Waschmaschine, welche zum Waschen des eingebrachten Gutes gemäß einem Umwälzverfahren für die eingesetzte Waschlauge eingerichtet ist und eine Speichereinheit für gebrauchtes Spülwasser aufweist. Der Strahler umgibt eine Leitung, durch welche Waschlauge umgewälzt, das heißt aus einem Sumpfbereich der Kammer abgepumpt und in eine in der Kammer rotierende Trommel mit dem zu behandelnden Gut gefördert wird. Ultraviolettes Licht aus dem Strahler beaufschlagt die Waschlauge und vernichtet eventuell vorhandene Bakterien und andere Mikroorganismen wie Viren, Pilze und Algen (alle Mikroorganismen nachfolgend nur „Keime" genannt) in der Waschlauge. Allerdings ist der Strahler nur so lange wirksam, wie das Waschen dauert; er ist nicht tauglich zum Einsatz gegen Keime, die sich nach dem Beenden des Waschen und nach Herausnehmen des gewaschenen Gutes in der von der zum Waschen oder Spülen benutzten Flüssigkeit noch feuchten, eventuell noch einen Rest dieser Flüssigkeit enthaltenden Kammer bilden können.Such a domestic appliance is apparent from DE 43 42 049 C2. The household appliance described is a washing machine, which is set up for washing the material introduced according to a circulation process for the washing liquor used and has a storage unit for used rinse water. The radiator surrounds a conduit through which wash liquor is circulated, that is, pumped out of a sump area of the chamber and conveyed into a drum rotating in the chamber with the material to be treated. Ultraviolet light from the radiator impinges the wash liquor and destroys any bacteria and other microorganisms such as viruses, fungi and algae (all microorganisms hereafter referred to as "germs") in the wash liquor, but only works as long as the wash lasts; it is not suitable for use against germs which, after the end of the washing and after removal of the washed product in the liquid used by the washing or rinsing, may still possibly form a residue of this liquid-containing chamber.
Aus der DE 32 32 057 A1 geht eine Waschmaschine hervor, bei der eine Zufuhr von Ozon zur Beseitigung unerwünschter Keime vorgesehen ist. Zwar ist Ozon gegen derartige Keime in der Tat wirksam, jedoch haben in Anbetracht seiner bleichenden Wirkung auf farbige Textilien, seines unangenehmen Geruches und seiner Reizwirkung auf den menschlichen Organismus schwerste Bedenken seine praktische Anwendung bislang nicht erlaubt.From DE 32 32 057 A1 discloses a washing machine, in which a supply of ozone to eliminate unwanted germs is provided. Although ozone is indeed effective against such germs, its bleaching effect on colored textiles, its unpleasant odor, and its irritating effect on the human organism have not yet allowed its practical application.
Neben diesen bekannten Waschmaschinen sind auch Hausgeräte, insbesondere Geschirrspülmaschinen, bekannt, in denen im Anschluss an einen Spülprozess Maschinenkomponenten durch ohnehin vorhandene oder speziell vorgesehene
Einrichtungen getrocknet werden, um Anhaften und Verklumpen von Waschmitteln zu vermeiden, welche für einen nachfolgenden Spülprozess zudosiert werden. Dazu wird verwiesen auf die Dokumente DE 36 06 053 C1 , WO 93/18701 A1 , DE 103 55 139 A1 , WO 03/071917 A2, WO 2005/060813 A1 und WO 2005/060821 A1 .In addition to these known washing machines, home appliances, in particular dishwashers, are known in which, following a rinsing process, machine components are present or provided for in any case Be dried facilities to prevent sticking and clumping of detergents, which are dosed for a subsequent rinsing process. Reference is made to the documents DE 36 06 053 C1, WO 93/18701 A1, DE 103 55 139 A1, WO 03/071917 A2, WO 2005/060813 A1 and WO 2005/060821 A1.
Von dem erwähnten Stand der Technik ausgehend liegt der nachfolgend darzulegenden Erfindung die Aufgabe zu Grunde, das bekannte Hausgerät dahingehend weiter zu bilden, dass eine Ausbreitung von Keimen verhindert wird, welche sich ohne weitere Maßnahme nach dem Behandeln des Gutes und dem Herausnehmen des behandelten Gutes aus dem Hausgerät in der von der zum Behandeln benutzten Flüssigkeit noch feuchten, eventuell noch einen Rest dieser Flüssigkeit enthaltenden Kammer bilden könnten.Starting from the cited prior art, the invention to be presented below is based on the object of further developing the known household appliance in such a way that the spread of germs is prevented which, without further action, after treating the material and removing the treated material the home appliance in the still used by the liquid used for treating, possibly could still form a residue of this liquid-containing chamber.
Zur Lösung dieser Aufgabe angegeben wird ein Hausgerät mit einer Kammer, welche eingerichtet ist zum Behandeln eines Gutes mit einer Flüssigkeit und einen Sumpfbereich aufweist, an den eine Pumpeinrichtung zum Abpumpen von Flüssigkeit aus der Kammer angeschlossen ist, und einem Strahler zum Erzeugen eines ultravioletten Lichtes, bei welchem Hausgerät der Strahler zum Bestrahlen des Sumpfbereiches mit dem Licht eingerichtet ist.To solve this object, a domestic appliance is provided with a chamber which is adapted to treat a product with a liquid and a sump region to which a pumping device for pumping liquid out of the chamber is connected, and a radiator for generating an ultraviolet light, in which domestic appliance the radiator is set up to irradiate the sump area with the light.
Erfindungsgemäß wird demnach das Bestrahlen genau dort durchgeführt, wo hauptsächlich mit einer Belastung des Hausgerätes durch Keime, die sich in einer von einem vorausgegangen Behandlungsprozess hinterbliebenen Feuchte ausbreiten könnten, zu rechnen ist.According to the invention, therefore, the irradiation is carried out exactly where it is to be expected mainly with a load of the household appliance by germs that could spread in a moisture left behind by a previous treatment process.
Der Strahler umfasst beispielsweise einen flüssigkeitsdichten Zylinder aus Quarzglas oder geeignetem, für die ultraviolette Strahlung durchlässigem und entsprechend beständigem Kunststoff, in welchen die eigentliche Quelle für die ultraviolette Strahlung eingesetzt ist.The emitter comprises, for example, a liquid-tight cylinder of quartz glass or suitable, permeable to ultraviolet radiation and correspondingly resistant plastic, in which the actual source of ultraviolet radiation is used.
Bevorzugt ist ein Strahler, der eingerichtet ist zur Erzeugung des Lichtes mit einer bevorzugten Wellenlänge von 253,7 nm, als einem Wellenlängenspektrum, welches um diese Wellenlänge zentriert ist.Preferably, a radiator adapted to generate the light having a preferred wavelength of 253.7 nm as a wavelength spectrum centered around that wavelength.
Weiter bevorzugt ist ein Hausgerät, bei dem der Strahler einen Schirm aufweist, welcher verhindert, dass ein gegen das Licht empfindliches Teil, insbesondere zu behandelndes
Gut, bestrahlt wird. Dies ist insbesondere dann von Bedeutung, wenn das Hausgerät eine Waschmaschine ist, da man in der Regel Wäsche einer ultravioletten Strahlung aufgrund derer bleichender Wirkung nicht aussetzen möchte. Mit zusätzlichem Vorzug ist dieser Schirm schwenkbar, beispielsweise um dann, wenn er nicht benötigt wird, in eine einen Behandlungsprozess nicht störende Stellung geschwenkt zu werden.Further preferred is a household appliance, in which the radiator has a screen, which prevents a sensitive part against the light, in particular to be treated Good, is irradiated. This is particularly important if the appliance is a washing machine, because you usually do not want to suspend laundry ultraviolet radiation due to their bleaching effect. With additional preference, this screen is pivotable, for example, when it is not needed to be pivoted into a treatment process not disturbing position.
Ebenfalls bevorzugt ist eine Weiterbildung des Hausgeräts, bei der an die Pumpeinrichtung eine Ablaufleitung aufweist, und bei der in der Ablaufleitung ein zusätzlicher Strahler zum Erzeugen eines ultravioletten Lichtes und Bestrahlen der Ablaufleitung angeordnet ist. Derart wird die Behandlung mit ultravioletter Strahlung ausgedehnt über den Sumpfbereich der Kammer hinaus, und somit eine umfassende Beseitigung unerwünschter Keime sichergestellt.Also preferred is a development of the domestic appliance, in which the pumping device has a drain line, and in which in the drain line, an additional radiator for generating an ultraviolet light and irradiating the drain line is arranged. Thus, treatment with ultraviolet radiation is extended beyond the sump area of the chamber, thus ensuring complete elimination of unwanted germs.
Besonders bevorzugt ist ein Hausgerät, welches zusätzlich eine Trockeneinrichtung, insbesondere eine Trockeneinrichtung umfassend einen Ventilator, zum Trocknen der Kammer aufweist, um somit auszuschließen, dass nach einer erfolgreichen Bestrahlung des Sumpfbereiches eingewanderte Keime ein insbesondere feuchtes Milieu vorfinden, in dem sie sich ausbreiten können. Diese Trockeneinrichtung kann mit weiterem Vorzug eine der Kammer zugeordnete Wärmequelle zum Beschleunigen des Trocknens umfassen. Dabei kann mit zusätzlichem Vorzug der Strahler selbst die Wärmequelle sein; mit gleichem Vorzug kann auch oder zusätzlich ein Heizstab zur Erwärmung der Flüssigkeit zum Behandeln des Gutes die Wärmequelle sein - was insbesondere in einem als Waschmaschine ausgebildeten Hausgerät in Betracht kommt.Particularly preferred is a domestic appliance, which additionally has a drying device, in particular a drying device comprising a fan for drying the chamber, so as to exclude that after a successful irradiation of the sump area immigrated germs find a particular moist environment in which they can spread. This drying device may more preferably comprise a heat source associated with the chamber for accelerating drying. In this case, with additional preference, the radiator itself can be the heat source; with equal preference may also or additionally be a heating element for heating the liquid for treating the material, the heat source - which comes in particular in a trained as a washing machine domestic appliance into consideration.
Mit weiterem Vorzug sind in der Trockeneinrichtung ein Zuluftkanal zum Zuleiten trockener Luft aus einer Umgebung des Hausgeräts in die Kammer sowie ein Abluftkanal zum Ableiten feuchter Abluft aus der Kammer vorgesehen.With further preference, a supply air duct for supplying dry air from an environment of the domestic appliance into the chamber as well as an exhaust duct for draining moist exhaust air from the chamber are provided in the drying device.
Mit ebenfalls weiterem Vorzug ist in dem Hausgerät ein Sensor, besonders ein Feuchtigkeitssensor, zum Steuern des Trocknens vorgesehen, wobei diese Steuern durch eine grundsätzlich bekannte und vorliegend entsprechend ertüchtigte Steuereinrichtung, an welche der Sensor angeschlossen ist, erfolgen kann.
Das erfindungsgemäße Hausgerät oder eine seiner soeben beschriebenen bevorzugten Weiterbildungen ist insbesondere ausgebildet als Waschmaschine zum Waschen des Gutes. Dabei ist mit weiterem Vorzug in der Kammer eine drehbare Trommel zum Aufnehmen des Gutes angeordnet.With a further preference, a sensor, in particular a moisture sensor, for controlling the drying is provided in the domestic appliance, wherein these controls can be effected by a basically known and, in the present case, suitably adapted control device to which the sensor is connected. The household appliance according to the invention or one of its preferred developments just described is in particular designed as a washing machine for washing the goods. In this case, a rotatable drum for receiving the goods is arranged with further preference in the chamber.
Ausführungsbeispiele der Erfindung werden nachfolgend anhand der Zeichnung beschrieben.Embodiments of the invention are described below with reference to the drawing.
Die einzige Figur der Zeichnung zeigt ein Hausgerät in Form einer Waschmaschine. Die Darstellung ist schematisiert und symbolisch gehalten, um die vorliegend besonders bedeutsamen Aspekte herauszustellen.The sole figure of the drawing shows a household appliance in the form of a washing machine. The depiction is schematic and symbolic in order to highlight the aspects that are of particular importance here.
Die Waschmaschine 18 zum Behandeln, namentlich Waschen, eines Gutes 20, hier repräsentiert durch zwei Textilstücke 20, umfasst eine Trommel 1 zum Aufnehmen dieser Textilstücke 20, welche Trommel 1 rotierbar in einem Laugenbehälter 2 aufgehängt ist. Der Laugenbehälter 2 wird zum Behandeln des Gutes 20 zum Teil mit einer Waschlauge oder Spüllauge gefüllt, wie ersichtlich an der gestrichelten und gewellten Linie. Diese Lauge füllt den Laugenbehälter 2 ausgehend von einem Sumpfbereich 19 bis zu einer zweckmäßigen Höhe. Wird die Lauge aus dem Laugenbehälter 2 entfernt, so bleibt dieser in seinem unteren Bereich, hier namhaft gemacht und dargestellt als Sumpfbereich 19, feucht; unter Umständen kann auch ein Rest der Lauge verbleiben. Aus diesem Grunde bietet der Sumpfbereich 19 nach vollendetem Behandeln eines Gutes 20 ein Milieu, welches die Ausbreitung verschiedener mikrobieller Keime begünstigen kann. Um eine solche Ausbreitung auszuschließen ist im Sumpfbereich 19 ein Strahler 3 zum Bestrahlen des Sumpfbereiches 19 mit einem ultravioletten Licht vorgesehen. Ultraviolettes Licht verfügt bekanntlich über eine starke Desinfektionswirkung und ist deshalb geeignet, den Sumpfbereich 19 wirksam zu desinfizieren.The washing machine 18 for treating, namely washing, a product 20, represented here by two textile pieces 20, comprises a drum 1 for receiving these textile pieces 20, which drum 1 is suspended rotatably in a tub 2. The tub 2 is partially filled with a wash or rinse liquor to treat the product 20, as can be seen in the dashed and wavy line. This liquor fills the tub 2, starting from a sump area 19 to an appropriate height. If the liquor is removed from the tub 2, it remains moist in its lower area, here named and shown as the sump area 19; Under certain circumstances, a residue of the liquor may remain. For this reason, the swamp area 19 after completion of treatment of a material 20 provides a milieu which can favor the propagation of various microbial germs. In order to prevent such a spread, a radiator 3 for irradiating the sump region 19 with an ultraviolet light is provided in the sump region 19. Ultraviolet light is known to have a strong disinfecting effect and is therefore capable of effectively disinfecting the sump area 19.
Die Lauge gelangt aus dem Sumpfbereich 19 über eine Ablauf leitung 17, in welcher hintereinander ein Flusenfilter 5, ein zusätzlicher Strahler 4 zum Desinfizieren der Ablaufleitung 17 mit ultraviolettem Licht und eine Pumpe 6 angeordnet sind. Hinter der Pumpe 6 gelangt die Wasch- oder Spüllauge über ein entsprechend schaltbares Ventil entweder zu einem Ablaufschlauch 7 und dort in ein Abwassernetz außerhalb der Waschmaschine 18, oder über eine Umwälzleitung 8 in die Trommel 1 zurück. Mit Hilfe
der Umwälzleitung 8 kann ein Waschprozess realisiert werden, beidem die Waschlauge mittels der Pumpe 6 und über die Umwälzleitung 8 umgewälzt wird.The liquor passes from the sump area 19 via a drain line 17, in which one behind the other a lint filter 5, an additional radiator 4 for disinfecting the drain line 17 with ultraviolet light and a pump 6 are arranged. Behind the pump 6, the washing or rinsing eye passes through a corresponding switchable valve either to a drain hose 7 and there in a sewer network outside the washing machine 18, or via a recirculation line 8 in the drum 1 back. With help the circulation line 8, a washing process can be realized, in which the wash liquor is circulated by means of the pump 6 and the circulation line 8.
Über einen Frischwassereinlass 13 und eine Frischwasserleitung 15 nebst geeigneter, schaltbarer Ventilanordnung kann dem Laugenbehälter 2 Frischwasser aus einem entsprechenden Frischwassernetz außerhalb der Waschmaschine 18 zugeführt werden.Via a fresh water inlet 13 and a fresh water line 15 together with a suitable, switchable valve arrangement, fresh water from a corresponding fresh water network outside the washing machine 18 can be supplied to the tub 2.
Ultraviolettes Licht, welches zur Desinfektion sinnvoll eingesetzt werden kann, hat auch die Eigenschaft, in einer feuchten und sauerstoffhaltigen Umgebung eine starke Bleichwirkung auszuüben und außerdem Textilmaterial anzugreifen. Somit kann es unter Umständen erforderlich sein, entsprechende empfindliche Teile, insbesondere Waschgut 20, von solchem Licht abzuschirmen. Zu diesem Zweck ist der Strahler 3 mit einem schwenkbaren Schirm 14 (nur schematisch dargestellt) versehen. Wenn nach Beendigung des Waschprozesses der Sumpfbereich 19 mittels des Strahlers 3 desinfiziert wird, kann der Schirm 14 so geschwenkt werden, dass das Waschgut 20 von dem Licht abgeschirmt ist. Während eines Waschprozesses, bei welchem der Strahler 3 regelmäßig nicht benutzt wird, kann der Schirm 14 in eine Position geschwenkt werden, in der er von der rotierenden Trommel 1 möglichst weit entfernt ist und den Waschprozess somit nicht stört.Ultraviolet light, which can be usefully used for disinfection, also has the property of exerting a strong bleaching action in a humid and oxygen-containing environment and also of attacking textile material. Thus, under certain circumstances, it may be necessary to shield corresponding sensitive parts, in particular laundry 20, from such light. For this purpose, the radiator 3 is provided with a pivotable screen 14 (shown only schematically). If after the completion of the washing process, the sump area 19 is disinfected by means of the radiator 3, the screen 14 can be pivoted so that the laundry 20 is shielded from the light. During a washing process, in which the radiator 3 is not used regularly, the screen 14 can be pivoted to a position in which it is as far as possible from the rotating drum 1 and thus does not interfere with the washing process.
Um eine wirksame Trocknung des Sumpfbereiches 19 zu erreichen, ist eine Trockeneinrichtung 9, 10, 1 1 , 12 umfassend einen Zuluftkanal 9 zum Zuführen trockener Luft aus einer Umgebung der Waschmaschine 18 in die Kammer 2 vorgesehen, und außerdem ein Abluftkanal 10 zum Abführen feuchter Abluft aus der Kammer 2. Zur Unterstützung einer entsprechenden Luftzirkulation ist in dem Zuluftkanal 9 ein Ventilator 1 1 vorgesehen. Der Zuluftkanal 9 bringt die trockene Luft zweckmäßig gleich in den Sumpfbereich 19; dahingegen ist der Abluftkanal 10 an einem Bereich der Kammer 2 abseits des Sumpfbereiches 19 angeschlossen. Der Abluftkanal 10 mündet in Abluftöffnungen 12, aus denen die Abluft aus der Waschmaschine 18 hinaus gelangt. Diese Abluftöffnungen 12 befinden sich beispielsweise in einer Waschmittelschublade, wie sie üblicher Weise zur Dosierung von Waschmittel verwendet wird. Auf diese Weise wird auch die Waschmittelschublade getrocknet und somit in einen dauerhaft gegen die Ausbreitung von Keimen sicheren Zustand versetzt.
Der Strahler 3 kann zusätzlich vorteilhaft benutzt werden, um den Sumpfbereich 19 mit der Wärme, die er neben dem Licht erzeugt, zu trocknen. Dadurch wird die Stabilität des Sumpfbereiches 19 gegen die Ausbreitung von Keimen verbessert. Außer dem Strahler 3 kann auch ein (in einer üblichen Waschmaschine immer vorhandener) Heizstab 16 (ebenfalls nur schematisch angedeutet) zum Erwärmen des Sumpfbereiches 19 zum Zwecke se i n e r Trockn u n g be n utzt we rde n .In order to achieve effective drying of the sump region 19, a drying device 9, 10, 11, 12 comprising a supply air duct 9 for supplying dry air from an environment of the washing machine 18 into the chamber 2, and also an exhaust duct 10 for removing moist exhaust air from the chamber 2. To support a corresponding air circulation in the supply air duct 9, a fan 1 1 is provided. The supply air duct 9 brings the dry air expedient equal to the sump area 19; By contrast, the exhaust duct 10 is connected to a region of the chamber 2 away from the sump area 19. The exhaust duct 10 opens into exhaust openings 12, from which the exhaust air from the washing machine 18 also passes. These exhaust openings 12 are located for example in a detergent drawer, as it is commonly used for dosing detergent. In this way, the detergent drawer is dried and thus placed in a durable against the spread of germs safe state. In addition, the radiator 3 can be advantageously used to dry the sump area 19 with the heat which it produces in addition to the light. This improves the stability of the sump region 19 against the spread of germs. In addition to the radiator 3, a heating rod 16 (which is always present in a conventional washing machine) (also indicated only schematically) can be used for heating the sump region 19 for the purpose of drying.
Der bereits erwähnte Schirm 14 am Strahler 3 kann zusätzlich zur Abschirmung des empfindlichen Gutes 20 auch dazu dienen, einer Bedienperson eine Beobachtung der von dem Strahler 3 ausgehenden Strahlung durch ein üblicher Weise vorhandenes Schauglas in einer Tür des Laugenbehälters 2 zu ermöglichen. Da das in einer solchen Tür üblicher Weise eingesetzte Natronsilikatglas undurchlässig für ultraviolette Strahlung ist, ist dabei eine Schädigung der Bedienperson nicht zu befürchten. Schließlich kann der Schirm auch eingesetzt werden, um die Strahlung von dem Strahler 3 selektiv zu verschiedenen Teilbereichen des Sumpfbereiches 19 zu führen. Im Rahmen einer derartigen Konfiguration muss der Strahler 3 selbst nicht ohne weiteres stets sämtliche zu behandelnde Teilbereiche des Sumpfbereiches 19 ausleuchten, wodurch sich eine gewisse konstruktive Freiheit bei der Auslegung der Waschmaschine 18 ergibt.The already mentioned screen 14 on the radiator 3 can also serve to shield the sensitive material 20 to allow an operator to observe the emanating radiation from the radiator 3 by a conventional manner present sight glass in a door of the tub 2. Since the Natronsilikatglas usually used in such a door is impermeable to ultraviolet radiation, damage to the operator is not to be feared. Finally, the screen can also be used to selectively guide the radiation from the radiator 3 to different subregions of the sump region 19. Within the scope of such a configuration, the emitter 3 itself does not always have to illuminate readily all subregions of the sump area 19 to be treated, which results in a certain degree of constructive freedom in the design of the washing machine 18.
