Description
Die Erfindung betrifft ein Saugreinigungsgerät gemäss dem Oberbegriff des ersten Anspruchs.The invention relates to a suction cleaning device according to the preamble of the first claim.
Bei einem bekannten Saugreinigungsgerät dieser Art (NL-A 7 513 513) ist ein Reinigungswasser-Aufnahmeraum zwischen konzentrisch zueinander angeordneten Wänden des Gerätegehäuses gebildet. Innerhalb des inneren konzentrischen Rohrabschnittes befindet sich ein Schmutzaufnahmeraum, in welchen ein Schmutzsammelbehälter lösbar eingesetzt ist. Dabei ist der Reinigungswasser-Aufnahmeraum vom Schmutzaufnahmeraum getrennt, so dass Reinigungwasser nicht in den Schmutzaufnahmeraum gelangen kann. Bei einem so ausgebildeten Saugreinigungsgerät ist für die Herstellung des doppelwandigen Gehäuses ein erheblicher technischer Aufwand erforderlich, wobei der Reinigungswasser-Aufnahmeraum in jedem Betriebsfall des Saugreinigungsgerätes mit transportiert wird.In a known suction cleaning device of this type (NL-A 7 513 513), a cleaning water receiving space is formed between walls of the device housing which are arranged concentrically to one another. Within the inner concentric pipe section there is a dirt holding space in which a dirt collecting container is detachably inserted. The cleaning water holding space is separated from the dirt holding space so that cleaning water cannot get into the dirt holding space. In the case of a suction cleaning device designed in this way, a considerable technical outlay is required for the production of the double-walled housing, the cleaning water receiving space being transported in every operating case of the suction cleaning device.
Es ist auch ein Saugreinigungsgerät bekannt (GB-A- 1 121 225), bei dem durch die Wände des Gehäuses ein Schmutzaufnahmeraum gebildet ist. Dieser Schmutzaufnahmeraum stellt zugleich einen Schmutzsammelbehälter für aufgesaugtes Schmutzwasser dar. Innerhalb dieses Schmutzaufnahmeraums ist ein Behälter als Reinigungswasser-Aufnahmeraum lösbar angeordnet. Dieser Behälter schwimmt jedoch in dem aufgesaugten Schmutzwasser. Bei diesem Aufbau ist somit keine Trennung zwischen dem Schmutzaufnahmeraum und dem Behälterfürdie Reinigungswasser- aufnahme gegeben, so dass der Behälter stets von dem rückgesaugten Schmutzwasser benetzt wird. Es erschwert sich dadurch die Handhabung beim Füllen des herausgenommenen Behälters durch Tropfwasser bzw. eine vorhergehende Reinigung von Hand erforderlich. Ausserdem muss vor dem Saugen von trockenem Gut der Schmutzaufnahmeraum getrocknet werden. Andernfalls verklebt der aufgenommene Staub an den Wänden des Schmutzaufnahmeraumes und bildet unhygienische Ablagerungen.A suction cleaning device is also known (GB-A-1 121 225), in which a dirt holding space is formed by the walls of the housing. This dirt holding space also represents a dirt collecting container for sucked up dirty water. Within this dirt holding space, a container is detachably arranged as a cleaning water holding space. However, this container floats in the soiled dirty water. With this construction, there is therefore no separation between the dirt holding space and the container for the cleaning water absorption, so that the container is always wetted by the sucked back dirty water. This makes it difficult to handle when filling the removed container with dripping water or prior cleaning by hand. In addition, the dirt holding area must be dried before vacuuming dry goods. Otherwise, the dust picked up sticks to the walls of the dirt holding space and forms unsanitary deposits.
Schliesslich ist auch ein Saugreinigungsgerät bekannt (US-A-3 180, 071), das im Gehäuse lediglich einen Schmutzaufnahmeraum für aufgesaugtes Schmutzwasser aufweist. Ein Reinigungswasser-Aufnahmeraum ist dabei im Gehäuse nicht vorgesehen. Es ist lediglich eine durch den Boden des Schmutzaufnahmeraumes in den oberen Abschnitt des Schmutzaufnahmeraumes geführte Absaugleitung mit einem am oberen Ende vorgesehenen Schwimmerventil vorgesehen, das bei maximalem Wasserstand im Schmutzaufnahmeraum schliesstFinally, a suction cleaning device is also known (US Pat. No. 3,180,071) which has only a dirt holding space in the housing for soiled waste water. A cleaning water receiving space is not provided in the housing. All that is provided is a suction line which is led through the floor of the dirt holding space into the upper section of the dirt holding space and has a float valve provided at the upper end which closes at maximum water level in the dirt holding space
Der Erfindung liegt die Aufgabe zugrunde, bei einem Saugreinigungsgerät gemäss dem Oberbegriff des ersten Patentanspruchs Massnahmen zu treffen, durch die ein einfacher Geräteaufbau ermöglicht wird und beim Saugen von trockenem Gut der Reinigungswasser-Aufnahmeraum nicht mitgeführt werden muss.The invention has for its object to take measures in a suction cleaning device according to the preamble of the first claim, by means of which a simple device construction is made possible and when cleaning dry material the cleaning water receiving space does not have to be carried along.
Die Lösung dieser Aufgabe erfolgt gemäss der Erfindung durch die kennzeichnenden Markmale des ersten Patentanspruchs.This object is achieved according to the invention by the characterizing features of the first claim.
Bei einem Aufbau eines Saugreinigungsgerätes gemäss der Erfindung braucht das Gerätegehäuse nicht doppelwandig ausgebildet zu werden und der Behälter für die Aufnahme des Reinigungswassers kann bei Bedarf in den Schmutzaufnahmeraum eingestellt werden. Dabei sind der Schmutzaufnahmeraum, der Schmutzsammelbehälter und der Behälter für das Reinigungswasser getrennte Räume. Eine Benetzung des Schmutzaufnahmeraumes und des Behälters für das Reinigungswasser tritt dabei durch zurückgesaugtes Schmutzwasser nicht ein. Es ist für den Behälter zur Reinigungswasser-Aufnahme auch kein gesonderter Raum im Gerätegehäuse erforderlich. Beim Aufsaugen von trockenem Gut kann dann durch Herausnehmen des Behälters für das Reinigungswasser und des Schmutzsammelbehälters das gesamte Volumen des Schmutzaufnahmeraumes ausgenutzt werden. Dabei kann ein Filterbeutel entsprechender Grösse verwendet werden. Das eingesaugte Gut wird somit jeweils in einem dafür geeigneten besonderen Behältnis aufgefangen und kann zusammen mit demselben zu einem Entleerungsplatz transportiert werden. Wird der das feuchte Gut auffangende Schmutzsammelbehälter aus einer Folie hergestellt, dann kann er wie ein gefüllter Trockenfilter mit Inhalt weggeworfen werden.When constructing a suction cleaning device according to the invention, the device housing need not be double-walled and the container for holding the cleaning water can be placed in the dirt holding space if necessary. The dirt holding space, the dirt collecting container and the container for the cleaning water are separate spaces. Wetting of the dirt holding space and the container for the cleaning water does not occur as a result of the dirt water sucked back. No separate space is required in the device housing for the container for cleaning water absorption. When vacuuming up dry material, the entire volume of the dirt holding space can then be used by removing the container for the cleaning water and the dirt collecting container. A filter bag of the appropriate size can be used. The sucked-in material is thus collected in a special container suitable for it and can be transported together with the same to an emptying place. If the dirt collecting container that collects the moist material is made from a film, it can be thrown away with its contents like a filled dry filter.
Eine gute Raumausnützung ist möglich, wenn der Behälter für die Reinigungswasseraufnahme den Schmutzsammelbehälter umgibt. Wird der Schmutzsammelbehälter im Strömungsweg unmittelbar vor einem Schwimmerventil angeordnet, das dem Schmutzsammelbehälter zugeordnet ist, dann wird ein Überfüllen des Schmutzsammelbehälters im Betrieb sicher vermieden. Das Schwimmerventil wird dabei zweckmässig an einer Abdeckung des Schmutzsammelbehälters festgesetzt, so dass der Schmutzsammelbehälter frei von Einbauten ist.A good use of space is possible if the container for the cleaning water absorption surrounds the dirt collecting container. If the dirt collecting container is arranged in the flow path immediately in front of a float valve which is assigned to the dirt collecting container, overfilling of the dirt collecting container is reliably avoided during operation. The float valve is expediently attached to a cover of the dirt collecting container, so that the dirt collecting container is free of internals.
Die Erfindung ist nachfolgend anhand eines Ausführungsbeispiels näher erläutert.The invention is explained in more detail below using an exemplary embodiment.
In einem Gehäuse eines Saugreinigungsgerätes befindet sich ein Schmutzaufnahmeraum, in welchem ein Schmutzsammelbehälter angeordnet ist. Der Schmutzsammelbehälter lässt sich durch einen darüber angeordneten abnehmbaren Dekkel nach oben herausnehmen. Durch den Deckel und eine Abdeckung des Schmutzsammelbehälters ist ein Saugrohr geführt, das über einen Saugschlauch mit einem Saugmundstück zur Aufnahme von feuchtem oder trockenem Sauggut verbunden ist. Das aufgenommene Sauggut lagert sich im Schmutzsammelbehälter ab, während die mitgeführte Luft durch ein Schwimmerventil, das bei maximalem Wasserstand im Schmutzsammelbehälter schliesst, über eine Absaugleitung zu einem Sauggebläse strömt. Ein Aufnahmeraum für das Reinigungswasser ist aus wenigsten einem Behälter gebildet, der in das Gehäuse lösbar eingestellt wird. Er kann damit beim Saugen von trockenem Gut entfernt werden. An den Behälter ist eine Pumpe angeschlossen, mit der das Reinigungswasser im Bedarfsfall durch eine Sprühleitung zu einer mit dem Saugmundstück verbundenen Sprühdüse gefördert werden kann.In a housing of a suction cleaning device there is a dirt holding space in which a dirt collecting container is arranged. The dirt collection container can be removed upwards by means of a removable lid. A suction pipe is guided through the lid and a cover of the dirt collecting container, which is connected via a suction hose to a suction mouthpiece for receiving moist or dry suction material. The absorbed suction material is deposited in the dirt collection container, while the air that is carried flows through a float valve, which closes at maximum water level in the dirt collection container, via a suction line to a suction fan. A receiving space for the cleaning water is formed from at least one container, which is set detachably in the housing. It can be removed when vacuuming dry goods. A pump is connected to the tank with which the Reini supply water can be conveyed through a spray line to a spray nozzle connected to the suction nozzle if necessary.
Ein Aufnahmeraum für das Reinigungswasser ist aus wenigstens einem eigenständigen Behälter gebildet, der in das Gehäuse eingestellt wird. Dabei ist dieser Behälter lösbar im Gehäuse angeordnet, damit er beim Saugen von trockenem Gut entfernt werden kann. Hierzu ist es zweckmässig, den Behälter um den Schmutzaufnahmeraum herum anzuordnen, damit dessen Volumen beim Trockensaugen entsprechend vergrössert werden kann.A receiving space for the cleaning water is formed from at least one independent container that is placed in the housing. This container is detachably arranged in the housing so that it can be removed when vacuuming dry goods. For this purpose, it is expedient to arrange the container around the dirt holding space so that its volume can be increased accordingly when vacuuming dry.
Wird das Saugreingiungsgerät nur zum Aufsaugen von trockenem Sauggut verwendet, dann kann der geschlossene Schmutzsammelbehälter entfernt und statt dessen ein Staubfiltersack mit seiner Anschlussplatte auf das Saugrohr aufgeschoben werden. Nachdem infolge der Abdichtung des Schmutzsammelbehälters gegenüber der Absaugleitung mittels einer Ringdichtung keine Feuchtigkeit in den Schmutzsammetraum eindringen kann, braucht dieser Raum beim Saugen von trockenem Sauggut auch nicht getrocknet zu werden.If the vacuum cleaning device is only used to vacuum dry suction material, the closed dirt collection container can be removed and a dust filter bag with its connecting plate can be pushed onto the vacuum tube instead. Since no moisture can penetrate into the dirt collecting space due to the sealing of the dirt collecting container with respect to the suction line by means of a ring seal, this space also does not need to be dried when vacuuming dry suction material.
In dem auf Rädern gelagerten Gehäuse sind in der Betriebslage nebeneinander durch eine Kammerwand abgeteilt das Sauggebläse und der Schmutzaufnahmeraum angeordnet. Die ggf. abnehmbare Abdeckung des Schmutzsammelbehälters umgreift den nach innen ragenden Stutzen des Saugrohres luftdicht und lösbar. Im Schwimmerventil befindet sich eine Schwimmerkugel und ein vorgeschaltetes Schmutzfangsieb. Die Ausgangsleistung des Schwimmerventils ist luftdicht in eine Seitenöffnung des Schmutzsammelbehälters eingesetzt. Das Schwimmerventil kann dabei lösbar mit dem Schmutzsammelbehälter verbunden sein. Der Schmutzsammelbehälter ist damit bis auf die Öffnung für das Saugrohr und die Ausgangsleistung des Schwimmerventils im Betriebszustand geschlossen. Die Amganasleistung ist über eine Gummiringdichtung an die Absaugleitung zum Sauggebläse angschliessbar, die dicht durch die Trennwand geführt ist.In the housing mounted on wheels, in the operating position the suction fan and the dirt holding space are arranged next to one another by a chamber wall. The removable cover of the dirt collecting container, if applicable, grips the inwardly projecting connection piece of the suction pipe in an airtight and detachable manner. In the float valve there is a float ball and an upstream dirt trap. The output power of the float valve is inserted in an airtight manner in a side opening of the dirt collecting container. The float valve can be detachably connected to the dirt collecting container. The dirt collecting container is thus closed except for the opening for the suction pipe and the output of the float valve in the operating state. The Amganas output can be connected to the suction line to the suction fan via a rubber ring seal, which is guided tightly through the partition.
Wird hierbei mit dem Saugmundstück feuchtigkeitsbeladenes Sauggut aufgenommen, dann strömt dasselbe durch das Saugrohr in den Schmutzsammelbehälter ein. Im Schmutzsammelbehälter setzt sich das mitgeführte feuchte Sauggut auf dem Boden ab, während die Luft durch das bei noch nicht gefülltem Wasserbehälter offene Schwimmerventil und die Ausgangsleitung sowie die Absaugleitung zum Gebläse gesaugt wird. Das im oberen Abschnitt des Schmutzsammelbehälters angeordnete Schwimmerventil spricht erst dann an, wenn der Wasserstand eine entsprechende Höhe erreicht hat und die Gefahr besteht, dass Wasser in das Gebläse strömen kann. Durch den dichten Anschluss der Ausgangsleitung an die Absaugleitung wird der Eintritt von feuchter Luft in den Schmutzaufnahmeraum vermieden. Eine Reinigung des Schmutzaufnahmeraumes nach einem Nasssaugen ist somit nicht erforderlich. Nach dem Entfernen des Schmutzsammelbehälters, der durch Aushebevorrichtungen bei geöffnetem Deckel aus dem Schmutzsammelraum herausgehoben werden kann, lässt sich anstelle des Schmutzsammelbehälters ein Papierfilterbeutel einsetzen, der mit einer entsprechenen Öffnung in einer üblichen Anschlussplatte luftdicht auf den inneren Stutzen des Saugrohres aufgeschoben und dort mittels Halterungen gehalten werden kann. In dem Staubbeutel wird dann das trockene Sauggut ausgefiltert und die gereinigte Luft wird unmittelbar aus dem Schmutzsammelraum über die Absaugleitung in das Sauggebläse abgesaugt. Mangels einer Befeuchtung der Innenwände des Schmutzaufnahmeraumes beim Nasssaugen entstehen dann auch beim Trockensaugen an seinen Innenwänden keine Feinstaubanlagerungen. Auch ergibt sich durch das nebeneinander Anordnen des Schmutzsammelraumes und des Sauggebläses ein niedriger Schwerpunkt des Saugreinigungsgerätes und damit eine erhöhte Kippsicherheit, was insbesondere bei der Verwendung als Nasssauger von erheblichem Vorteil ist.If in this case moisture-laden suction material is taken up with the suction mouthpiece, the same flows through the suction pipe into the dirt collecting container. In the dirt collection container, the moist suction material carried is deposited on the floor, while the air is sucked through the float valve, which is open when the water container is not filled, and the outlet line and suction line to the blower. The float valve located in the upper section of the dirt collecting container only responds when the water level has reached a corresponding level and there is a risk that water can flow into the blower. The tight connection of the outlet line to the suction line prevents the entry of moist air into the dirt holding area. It is therefore not necessary to clean the dirt holding area after wet vacuuming. After removing the dirt collecting container, which can be lifted out of the dirt collecting space by lifting devices with the lid open, a paper filter bag can be used instead of the dirt collecting container, which is pushed airtight with a corresponding opening in a conventional connection plate onto the inner socket of the suction pipe and held there by means of brackets can be. The dry suction material is then filtered out in the dust bag and the cleaned air is sucked off directly from the dirt collecting space via the suction line into the suction fan. In the absence of humidification of the inner walls of the dirt holding space during wet vacuuming, no fine dust accumulation occurs on its inner walls even when vacuuming dry. The side-by-side arrangement of the dirt collecting space and the suction blower also results in a low center of gravity of the suction cleaning device and thus increased safety against tipping, which is particularly advantageous when used as a wet vacuum cleaner.
Im übrigen kann das Schwimmerventil auch mit der luftdicht auf den Schmutzsammelbehälter aufsetzbaren Abdeckung verbunden sein, so dass es beim Entleeren oder Reinigen des Schmutzsammelbehälters nicht stört.In addition, the float valve can also be connected to the cover which can be placed airtight on the dirt collecting container, so that it does not interfere with emptying or cleaning the dirt collecting container.
