Definitions

  • the invention relates to a vacuum cleaner according to the preamble of claim 1.
  • the outer and inner cover are attached to the housing via separate locks and each have a handle for opening. It can easily happen that the operator accidentally actuates the wrong lock or takes the wrong handle, so that the inner cover is opened instead of the outer cover or vice versa. Then this lid has to be closed again and the lock for the other lid has to be released. If the locking mechanism for the inner cover is accidentally actuated while the motor fan unit is running, it cannot be opened at all due to the negative pressure in the dust chamber, which also leads to unnecessary, annoying incorrect operation.
  • the handling parts and handles assigned to each lid make handling particularly difficult.
  • the invention has for its object to design a vacuum cleaner of this type so that incorrect operation when opening the inner and outer cover are avoided.
  • This object is achieved according to the invention in a vacuum cleaner of the generic type with the characterizing features of claim 1.
  • one handle of the outer cover is sufficient to open both covers and only one lock for the outer cover with respect to the housing is required. If, for example, the storage tray or the inner lid is to be accessible for removing one of the cleaning tools housed there while the engine is running, when the engine is running, only the outer lid has to be gripped by its handle and pivoted outwards. Due to the negative pressure prevailing in the dust chamber during operation of the vacuum cleaner, a suction force acts on the inner cover which, according to the invention, is greater than the holding force which acts between the inner and outer cover. As a result, the inner cover remains on the associated edge of the dust space when the outer cover is opened, so that it cannot be opened unintentionally.
  • the inner cover is also raised by lifting the outer cover, since then no closing force acts on the inner cover, which counteracts the holding force.

  • the design according to the invention ensures that the operator can only open that space to which he wants access in the respective operating state of the vacuum cleaner. If the lock for the outer lid is actuated during operation and the handle is pivoted upwards, the storage tray becomes accessible so that the cleaning tool that is no longer required can be replaced in the storage tray and another cleaning tool can be removed. To empty or replace the dust collector and collecting device, which always takes place when the vacuum cleaner is switched off, the same locking mechanism and handle are released or gripped in the same way, with both lids being pivoted together or removed from the housing, but only the receiving space for the dust filter and collection device is accessible while the storage tray remains closed.
  • the vacuum cleaner according to FIGS. 1 to 4 can be used both in the household and in commercial operations. It has a vacuum cleaner housing 2, which can be moved on the floor during operation with rear rollers 4 attached to the housing base 3 and a front support roller 6.

Description

Die Erfindung betrifft einen Staubsauger nach dem Oberbegriff des Anspruches 1.The invention relates to a vacuum cleaner according to the preamble of claim 1.

Bei einem bekannten Staubsauger dieser Art sind der Außen- und Innendeckel über gesonderte Verriegelungen am Gehäuse befestigt und weisen jeweils einen Griff zum Öffnen auf. Dabei kann es leicht vorkommen, daß die Bedienungsperson versehentlich die falsche Verriegelung betätigt oder den falschen Griff faßt, so daß anstelle des Außendeckels der Innendeckel oder umgekehrt geöffnet wird. Dann muß dieser Deckel wieder geschlossen und die Verriegelung für den anderen Deckel gelöst werden. Wenn versehentlich bei laufendem Motorgebläseaggregat die Verriegelung für den Innendeckel betätigt wird, läßt sich dieser infolge des im Staubraum herrschenden Unterdruck gar nicht öffnen, was ebenfalls zu einer unnötigen, lästigen Fehlbedienung führt. Durch die jedem Deckel zugeordneten Betätigungsteile und Griffe ist die Handhabung besonders erschwert.In a known vacuum cleaner of this type, the outer and inner cover are attached to the housing via separate locks and each have a handle for opening. It can easily happen that the operator accidentally actuates the wrong lock or takes the wrong handle, so that the inner cover is opened instead of the outer cover or vice versa. Then this lid has to be closed again and the lock for the other lid has to be released. If the locking mechanism for the inner cover is accidentally actuated while the motor fan unit is running, it cannot be opened at all due to the negative pressure in the dust chamber, which also leads to unnecessary, annoying incorrect operation. The handling parts and handles assigned to each lid make handling particularly difficult.

Der Erfindung liegt die Aufgabe zugrunde, einen Staubsauger dieser Art so auszubilden, daß Fehlbedienungen beim Öffnen des Innen-und Außendeckels vermieden sind. Diese Aufgabe wird bei einem Staubsauger der gattungsbildenden Art erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst.The invention has for its object to design a vacuum cleaner of this type so that incorrect operation when opening the inner and outer cover are avoided. This object is achieved according to the invention in a vacuum cleaner of the generic type with the characterizing features of claim 1.

Infolge der erfindungsgemäßen Ausbildung genügt der eine Griff des Außendeckels zum Öffnen beider Deckel und es ist auch nur eine Verriegelung für den Außendeckel gegenüber dem Gehäuse erforderlich. Soll beispielsweise die Ablageschale bzw. der Innendeckel beim Staubsaugen, als bei laufendem Motor, zur Entnahme eines der dort untergebrachten Reinigungswerkzeuge zugänglich sein, muß nur der Außendeckel an seinem Griff gefasst und nach außen geschwenkt werden. Durch den beim Betrieb des Staubsaugers im Staubraum herrschenden Unterdruck wirkt auf den Innendeckel eine Ansaugkraft, die erfindungsgemäß größer ist als die Haitekraft, die zwischen dem Innen-und Außendeckel wirkt. Dadurch bleibt der Innendeckel beim Öffnen des Außendeckels auf dem zugehörigen Rand des Staubraumes liegen, so daß dieser nicht unbeabsichtigt geöffnet werden kann. Andererseits wird bei ausgeschaltetem Staubsauger durch Anheben des Außendeckels der Innendeckel mit angehoben, da dann auf den Innendeckel keine Schließkraft wirkt, die der Haltekraft entgegenwirkt. Somit ist der Staubraum zum Auswechseln oder Reinigen der Staubfilter-und Sammeleinrichtung leicht zugänglich. Schließlich können bei ausgeschaltetem Staubsauger aber auch die beiden Deckel einfach und schnell voneinander gelöst werden, wenn aus dem Innendeckel ein Reinigungswerkzeug entnommen oder in diesen zurückgelegt werden soll. Hierzu braucht lediglich der Innendeckel vom Außendeckel weggedrückt zu werden, um die Haltekraft der Haltevorrichtung zu überwinden.As a result of the design according to the invention, one handle of the outer cover is sufficient to open both covers and only one lock for the outer cover with respect to the housing is required. If, for example, the storage tray or the inner lid is to be accessible for removing one of the cleaning tools housed there while the engine is running, when the engine is running, only the outer lid has to be gripped by its handle and pivoted outwards. Due to the negative pressure prevailing in the dust chamber during operation of the vacuum cleaner, a suction force acts on the inner cover which, according to the invention, is greater than the holding force which acts between the inner and outer cover. As a result, the inner cover remains on the associated edge of the dust space when the outer cover is opened, so that it cannot be opened unintentionally. On the other hand, when the vacuum cleaner is switched off, the inner cover is also raised by lifting the outer cover, since then no closing force acts on the inner cover, which counteracts the holding force. The dust chamber is therefore easily accessible for replacing or cleaning the dust filter and collecting device. Finally, when the vacuum cleaner is switched off, the two lids can also be easily and quickly detached from one another if a cleaning tool is to be removed from the inner lid or put back in it. For this purpose, only the inner cover needs to be pushed away from the outer cover in order to overcome the holding force of the holding device.

Durch die erfindungsgemäße Ausbildung ist sichergestellt, daß die Bedienungsperson jeweils nur denjenigen Raum öffnen kann, zu dem sie beim jeweiligen Betriebszustand des Staubsaugers Zugang haben will. Wird also während des Betriebes die Verriegelung für den Außendeckel betätigt und dieser am Griff tiach oben geschwenkt, dann wird die Ablageschale zugänglich, so daß das nicht mehr benötigte Reinigungswerkzeug in die Ablageschale zurückgelegt und ein anderes Reinigungswerkzeug entnommen werden kann. Zum Entleeren oder Auswechseln der Staubfifter- und Sammeleinrichtung, was stets bei ausgeschaltetem Staubsauger erfolgt, wird in gleicher Weise die-selbe Verriegelung und derselbe Griff gelöst bzw. gefasst, wobei beide Deckel gemeinsam verschwenkt bzw. vom Gehäuse abgenommen werden, aber nur der Aufnahmeraum für die Staubfilter- und Sammeleinrichtung zugänglich ist, während die Ablageschale verschlossen bleibt.The design according to the invention ensures that the operator can only open that space to which he wants access in the respective operating state of the vacuum cleaner. If the lock for the outer lid is actuated during operation and the handle is pivoted upwards, the storage tray becomes accessible so that the cleaning tool that is no longer required can be replaced in the storage tray and another cleaning tool can be removed. To empty or replace the dust collector and collecting device, which always takes place when the vacuum cleaner is switched off, the same locking mechanism and handle are released or gripped in the same way, with both lids being pivoted together or removed from the housing, but only the receiving space for the dust filter and collection device is accessible while the storage tray remains closed.

Der Staubsauger nach den Fig. 1 bis 4 kann sowohl im Haushalt als auch in Gewerbebetrieben genutzt werden. Er weist ein Staubsaugergehäuse 2 auf, das während des Betriebes mit am Gehäuseboden 3 befestigten rückwärtigen Laufrollen 4 und einer vorderen Stützrolle 6 auf dem Boden verfahrbar ist. Im Gehäuse 2 ist ein Motor-Gebläse-Aggregat 7 mit einem Elektromotor untergebracht. Es erzeugt einen Saugluftstrom, mit dem der zu entfernende Staub und Schmutz von Böden, Wänden, Leisten, Bildern oder dergleichen abgesaugt werden kann. Der Saugluftstrom strömt von einem (nicht dargestelften) Reinigungswerkzeug über eine Saug leitung 8 in eine im Gehäuse 2 untergebrachte Staubfilter-und Sammeleinrichtung 9, wo der staubhaltige Saugluftstrom gereinigt wird. Die Staubfilter- und Sammeleinrichtung 9 besteht vorzugsweise aus einem Papier- oder Stoffbeutel, der in bestimmten Zeitabständen ausgewechselt bzw. geleert und gereinigt werden muß. Nach Durchströmen dieser Einrichtung 9 verläßt der gereinigte Saugluftstrom das Staubsaugergehäuse 2 über (nicht dargestellte) Ausblasöffnungen.The vacuum cleaner according to FIGS. 1 to 4 can be used both in the household and in commercial operations. It has a vacuum cleaner housing 2, which can be moved on the floor during operation with rear rollers 4 attached to the housing base 3 and a front support roller 6. A motor-blower unit 7 with an electric motor is accommodated in the housing 2. It generates a suction air flow with which the dust and dirt to be removed can be extracted from floors, walls, moldings, pictures or the like. The suction air flow flows from a cleaning tool (not shown) via a suction line 8 into a dust filter and collecting device 9 accommodated in the housing 2, where the dust-containing suction air flow is cleaned. The dust filter and collecting device 9 preferably consists of a paper or cloth bag which has to be replaced or emptied and cleaned at certain intervals. After flowing through this device 9, the cleaned sow leaves gluftstrom the vacuum cleaner housing 2 via (not shown) discharge openings.

Die Staubfilter- und Sammeleinrichtung 9 liegt in einem Staubraum 10, der mit einem Innendeckei 11 verschließbar ist. Er liegt mit einem umlaufenden Rand 12 unter Zwischenlage einer Dichtung 13 auf einem entsprechenden Rand 14 des Staubraumes luftdicht auf.The dust filter and collecting device 9 lies in a dust chamber 10 which can be closed with an inner cover 11. It lies airtight with a peripheral edge 12 with the interposition of a seal 13 on a corresponding edge 14 of the dust chamber.

Der Innendeckel 11 ist als Ablageschale für verschiedene Reinigungswerkzeuge 15 (Fig. 2), wie eine Heizkörperbürste, Polster- oder Fugendüsen oder dergleichen ausgebildet. Mit diesen Werkzeugen 15 können nicht nur Fußböden, sondern auch die verschiedensten Einrichtungsgegenstände, wie Möbel, Bilderrahmen, Heizkörper oder dergleichen abgesaugt werden. Da beim Reinigen beispielsweise eines Wohnraumes die unterschiedlichsten Reinigungswerkzeuge notwendig werden, sind diese im Innendeckel stets schnell griffbereit, wodurch ein zügiges Arbeiten gewährleistet ist.The inner cover 11 is designed as a storage tray for various cleaning tools 15 (FIG. 2), such as a radiator brush, upholstery or crevice nozzles or the like. With these tools 15 not only floors, but also a wide variety of furnishings such as furniture, picture frames, radiators or the like can be extracted. Since a wide variety of cleaning tools are necessary when cleaning a living room, for example, they are always quickly at hand in the inner cover, which ensures quick work.

Zur Aufnahme der Reinigungswerkzeuge weist der Innendeckel 11 eine Vertiefung 11' oder (nicht dargestellte) Kiemmstücke auf, die an die Außenkonturen der aufzunehmenden Reinigungswerkzeuge angepasst sind. Dadurch können die nicht gebrauchten Reinigungswerkzeuge einfach und schnell in der jeweils günstigsten Lage aufbewahrt werden.To accommodate the cleaning tools, the inner cover 11 has a recess 11 'or gill pieces (not shown) which are adapted to the outer contours of the cleaning tools to be accommodated. This means that the unused cleaning tools can be stored quickly and easily in the most convenient location.

Der Innendeckel 11 und die in ihm angeordneten Reinigungswerkzeuge 15 sind vom Außendeckel 16 nach außen abgedeckt. Der Außendeckel 16 ist mit Steckscharnieren 18 an einer rückwärtigen Gehäusewand 17 gelenkig gelagert und an seinem vorderen Rand 16' mit vorzugsweise zwei mit Abstand nebeneinander angeordneten Rastfedern 19 am Gehäuse 2 lösbar befestigt. Die Federn 19 ragen mit einer Rastnase in zugehörige Gehäuseöffnungen, aus denen sie beim Abheben des Außendeckels 16 mit geringem Kraftaufwand herausgedrückt werden können.The inner cover 11 and the cleaning tools 15 arranged in it are covered by the outer cover 16 to the outside. The outer cover 16 is articulated with plug-in hinges 18 on a rear housing wall 17 and is detachably fastened to the housing 2 on its front edge 16 'with preferably two detent springs 19 arranged next to one another at a distance. The springs 19 protrude with a latching lug into associated housing openings, from which they can be pressed out with little effort when the outer cover 16 is lifted off.

Der Außendeckel 16 weist ferner eine quer zur Längsrichtung des Staubsaugergehäuses 2 verlaufende Grifföffnung 20 auf, in die die Bedienungsperson zum Öffnen des Deckels hineinfassen muß, um einen an die Vorderkante der Öffnung anschließenden, als Griff dienenden Deckelteil 23 fassen zu können.The outer lid 16 also has a transverse to the longitudinal direction of the vacuum cleaner housing 2 handle opening 20, into which the operator must reach to open the lid in order to be able to grip a lid part 23 which adjoins the front edge of the opening and serves as a handle.

In Schließstellung ist der Außendeckel 16 mit einer Rastvorrichtung 21 und einer Haliavorrichtung 22 mit dem Innendeckel 11 lösbar verbunden (Fig. 4).In the closed position, the outer cover 16 is detachably connected to the inner cover 11 with a latching device 21 and a halo device 22 (FIG. 4).

Die Rastvorrichtung 21 liegt in Strömungsrichtung des Saugluftstromes gesehen unmittelbar hinter der die Reinigungswerkzeuge 15 aufnehmenden Vertiefung 11'. Die Rastvorrichtung 21 besteht aus mindestens zwei mit Abstand nebeneinander angeordneten und vertikal nach oben über die Oberseite 24 des Innendeckels 11 ragenden Rastzungen 25, die mit einer Rastnase 26 in eine zugehörige Rastöffnung 27 eines auf der Innenseite 28 des Außendeckels 16 vorgesehenen Steges 29 ragt. Die Haltevorrichtung 22 besteht aus einem Magneten 30, vorzugsweise einem rechteckigen Magnetstück, das vorzugsweise in einer Offnung eines vor und oberhalb der Vertiefung 11' liegenden Quersteges 31 des Innendeckels 11 angeordnet ist. Dem Magneten 30 ist eine an der Innenseite 28 des Außendeckels 16 befestigte Magnetplatte 32 zugeordnet.The locking device 21 is located in the flow direction of the suction air stream directly behind the recess 11 'which receives the cleaning tools 15. The latching device 21 consists of at least two spaced-apart latching tongues 25 which project vertically upward above the top 24 of the inner cover 11 and which projects with a latching lug 26 into an associated latching opening 27 of a web 29 provided on the inside 28 of the outer lid 16. The holding device 22 consists of a magnet 30, preferably a rectangular magnet piece, which is preferably arranged in an opening of a transverse web 31 of the inner cover 11 lying in front of and above the recess 11 '. A magnet plate 32 attached to the inside 28 of the outer cover 16 is assigned to the magnet 30.

Die Haltekraft der Rastvorrichtung 21 und der Haltevorrichtung 22 ist jeweils größer als das Gewicht des Deckels 11 und der Werkzeuge 15, so daß sich der Innendeckel 11 nicht vom Außendeckel 16 lösen kann, wenn dieser bei ausgeschaltetem Staubsauger geöffnet wird. Dadurch werden hierbei beide Deckel gemeinsam angehoben, so daß der Staubraum zum Leeren bzw. Auswechseln des Staubfilter- und Sammelbehälters geöffnet wird.The holding force of the latching device 21 and the holding device 22 is in each case greater than the weight of the cover 11 and the tools 15, so that the inner cover 11 cannot be detached from the outer cover 16 if it is opened when the vacuum cleaner is switched off. As a result, both lids are lifted together, so that the dust chamber is opened for emptying or replacing the dust filter and collecting container.

Bei laufendem Staubsauger ist der im Staubraum 10 herrschende Unterdruck jedoch größer als die Haltekraft der Rast-und Haltevorrichtung 21 und 22, so daß beim Öffnen des Außendeckels 16 der Innendeckel 11 auf dem Rand 14 des Gehäuses 2 liegen bleibt und die Hattevorrichtung und Rastvorrichtung gelöst werden. Dadurch bleibt der Staubraum 10 geschlossen und es wird nur der Außendecket 16 abgehoben, so daß der Innendeckel 11 mit den Reinigungswerkzeugen 15 freiliegt.When the vacuum cleaner is running, however, the negative pressure prevailing in the dust chamber 10 is greater than the holding force of the latching and holding device 21 and 22, so that when the outer lid 16 is opened, the inner lid 11 remains on the edge 14 of the housing 2 and the hatching device and latching device are released . As a result, the dust chamber 10 remains closed and only the outer cover 16 is lifted off, so that the inner cover 11 with the cleaning tools 15 is exposed.

Um bei abgeschaltetem Staubsauger aus dem Innendeckel 11 ein Reinigungswerkzeug herausnehmen oder in dieses zurücklegen zu können, muß zunächst der Außendeckel 16 am Griff 23 gefasst und aufwärts geschwenkt werden oder vom Gehäuse 2 abgenommen werden. Danach werden die Rast- und Haltevorrichtung 21 und 22 gelöst, indem der Innendeckel 11 vom Außendeckel 16 weggezogen wird. Anschließend wird der Innendeckel 11 auf dem Rand 14 des Staubraumes 10 zurückgelegt, der Außendeckel 16 zurückgeschwenkt oder mit seinen Steckschamieren 18 in die Gehäusewand 17 gesteckt und dann der Außendeckel 16 zurückgeschwenkt, bis seine Rastfedern 19 in die zugehörigen Gehäuseöffnungen einrasten. Hierbei ist eine leicht lösbare Verbindung zwischen Außendeckel und Gehäuse hergestellt.In order to be able to take a cleaning tool out of the inner cover 11 or put it back in the vacuum cleaner when it is switched off, the outer cover 16 must first be gripped by the handle 23 and pivoted upward or be removed from the housing 2. The latching and holding device 21 and 22 are then released by pulling the inner cover 11 away from the outer cover 16. Then the inner cover 11 is replaced on the edge 14 of the dust chamber 10, the outer cover 16 is pivoted back or inserted with its plug-in hinges 18 into the housing wall 17 and then the outer cover 16 is pivoted back until its catch springs 19 snap into the associated housing openings. Here, an easily detachable connection between the outer cover and the housing is made.

Durch die Rast- und Haltevorrichtung 21 und 22 ist ausgeschlossen, daß die Bedienungsperson versehentlich den falschen Deckel öffnet. Vielmehr wird in Abhängigkeit vom jeweiligen Betriebszustand des Staubsaugers zwangsläufig nur der Raum geöffnet, der bei aus- oder eingeschaltetem Staubsauger gerade zugänglich sein muß, um die Staubfilter- und Sammeleinrichtung bzw. die Reinigungswerkzeuge aus dem Innendeckel entnehmen oder wieder in diesen einsetzen zu können.The locking and holding device 21 and 22 prevent the operator from accidentally opening the wrong cover. Rather, depending on the current operating state of the vacuum cleaner, only the space that must be accessible when the vacuum cleaner is switched on or off is inevitably open in order to be able to remove the dust filter and collection device or the cleaning tools from the inner cover or to reinsert them.

Claims (7)

1. Suction cleaner, comprising a motor fan unit which is located in a suction cleaner housing and generates a suction air blast which supplies dusty air flowing into the suction cleaner from a cleaning tool via a suction pipe to a dust filtering or dust collecting means such as a paper filter bag or the like, which is located in a dust chamber of the housing, which dust chamber can be locked by an inside cover which serves as a pan for depositing cleaning tools therein and which is covered by a lockable cover which is hinged to the housing and has a grip, characterised in that without a locking mechanism and a grip for the inside cover (11) being required, the inside cover (11) and the outside cover (16) are joined to each other by means of at least one holding device (22) which exerts a given tractive power on one of the covers, said tractive power being smaller than the underpressure which acts inside the dust chamber (10) with the motor fan unit (7) running and thus acts also on the inside cover (11).
2. Suction cleaner according to claim 1, characterised in that the inside cover (11) is held on the outside cover (16) by a magnetic force.
3. Suction cleaner according to claim 1 or 2, characterised in that the holding device (22) has a magnet (30), which is fastened preferably to the inside cover (11) and which is associated to a metal plate (32) fastened on the inside (28) of the outside cover (16).
