Description

Vacuum cleaner

Technical Field

The invention relates to a dust collector. In particular, the invention relates to a vacuum cleaner having a drive container and a separator container which is releasably connected to the drive container and has a handle for removal from the drive container and for carrying.

Background

Such a vacuum cleaner is described in EP2459044B1, in which the separator container is arranged perpendicular to the direction of travel of the vacuum cleaner and is removable and insertable vertically. The separator container can be removed upwards from the drive means container by means of a handle. However, the direct removal of the separator container is prevented by a further handle, which is arranged at the drive device container. The other handle must first be folded so that the handle of the separator container can be erected. Only then can the separator vessel be removed from the drive means vessel. Furthermore, it is not sufficient to pull out the separator vessel in a manner which is stable and reliable for the apparatus.

Disclosure of Invention

The problem underlying the present invention is therefore to provide a vacuum cleaner which provides a safe and intuitive self-positioning of the separator vessel with the drive means vessel and a user-clearly identifiable convenient release and release of the separator vessel without affecting the stable reliability of the vacuum cleaner.

According to the invention, this problem is solved by a vacuum cleaner having the features of claim 1. Advantageous embodiments and refinements of the invention emerge from the following dependent claims.

The advantages achievable with the invention are, in addition to a very simple, self-evident removal of the separator vessel from the drive device vessel, also an intuitive, self-evident positioning of the separator vessel in and/or at the drive device vessel. An ergonomic and user-friendly solution for removing and inserting a separator vessel in and/or at a drive means vessel is provided.

The invention relates to a vacuum cleaner having a drive container and a separator container having a handle, wherein the drive container and the separator container are releasably connected and the handle is arranged on the separator container such that it can be moved in a rotatable manner such that, when the handle is lifted in a rotating manner, the separator container is released from the drive container and can be removed upwards relative to the direction of travel of the vacuum cleaner.

With this structure, the separator container can be separated and removed from the drive device container by actuating the handle at the final position where the separator container is connected with the drive device container in the ready-to-operate position. This does not affect the stability of the vacuum cleaner and the drive unit container.

The well-recognized and directly accessible handle is preferably designed such that it enables one-handed operation both for inserting the separator container into the drive device container and for removing the separator container from the drive device container. The position information and the direction information relate to a traveling direction of the cleaner.

The drive device container preferably has a container unit in which the drive device is accommodated and a receiving unit in and/or at which the separator container can be releasably connected.

In a preferred embodiment, the drive container has a guide rail along which the separator container is guided when the handle is lifted in rotation. By the rotary lifting of the handle, the separator container is moved upwards on the guide rails and can be removed in a simple manner, wherein the separator container is guided by the guide rails. Thereby, the stability and reliability of the cleaner when removing the separator vessel is further ensured.

Preferably, the drive container has lateral securing elements which are designed to secure the handle in the final position and to release the handle from the lateral securing elements when the handle is lifted in rotation. By the pivoting lifting of the handle, the separator container slides upwards on the guide rail and the handle is now preferably unlocked from the laterally mounted fastening elements of the drive device container. The fixing element is preferably designed as a latch, more preferably as a snap hook. In the final position, in which the separator container is connected with the drive means container in the ready-for-operation position, the separator container and the drive means container are latched such that the required tightness of the air flow guide is provided.

Preferably, all mechanically movable fixing and/or arresting elements for fixing and/or arresting the separator container at the drive device container are arranged at the top of the drive device container and at the handle of the separator container. The arrangement of all mechanically movable fixing and/or stopping elements at the top of the cleaner ensures a high dust insensitivity. Thus, the dripping of dust is ensured due to the positioning of the top. This direct fixed attachment of all the fixing and stopping geometries to the rotatable handle also ensures a high degree of robustness and dust insensitivity. An additional movable transmission element in the form of a slide for locking the separator vessel with the drive means vessel is not necessary. When the separator vessel is removed, all stopping points and guide profiles are freely accessible and can be cleaned if necessary. In order to fix the separator container in and/or at the drive device container, the drive device container preferably has a lateral fixing element arranged at the top of the drive device container and a horizontally acting stop.

In a preferred embodiment, the handle has a rolling element at the side wall, which rolling element is arranged above the axis of rotation and changes its angular position when the handle is raised rotationally. Preferably, the rolling elements are arranged radially above the axis of rotation. Preferably, the rolling elements are supported at the side walls of the handle at the drive means container. The angular position of the handle is changed by the rotation movement of the handle. The change in angular position in turn forces the separator vessel out of its final position, which it occupies when connected in an operationally ready manner with the drive means vessel. The rolling element preferably remains at the contact surface of the drive means container in the final position, which is preferably determined by the accessible engagement height of the handle. The separator container, which has been released from the drive container, can be removed on the guide rails by further lifting it.

Preferably, the end stop at the separator vessel and the end stop at the handle define the angular position. Thereby, the erected position of the handle is preferably also defined. Further preventing uncontrolled tipping of the separator vessel while being carried. The handle preferably remains in the centre of gravity of the emptying of the separator vessel. The handle is thus held in the other final position by the own weight of the separator during carrying. The handling and control of the separator vessel for emptying is thereby significantly improved.

In a preferred embodiment, the guide rail is designed such that the separator vessel can be placed vertically on the drive vessel. Preferably, the drive device container has an open-top contour in addition to the container unit in which the drive device is accommodated. The connection of the separator vessel to the drive vessel is preferably first made by inserting the separator vessel into the profile which is open at the top. The guide rail is preferably integrated at the side of the drive device container and is designed in the form of a funnel. Preferably, the guide rails are designed such that the separator vessel can initially be placed at a convenient, user-friendly vertical on the drive means vessel. The guide rail is preferably designed such that the separator container is slid with its handle into the retaining position of the drive means container by the own weight of the separator container and/or by pushing the separator container on the guide rail. The seat of the separator container is preferably arranged in the bottom of the drive means container when the handle is arranged in the stop position.

Preferably, the slope of the guide track increases with increasing depth in the drive means receptacle. The kinematics of movement required for introducing the separator vessel into the drive vessel are preferably such that the separator vessel can be removed and inserted almost vertically in and/or at the drive vessel located at the surface and sealed in the contact position. Preferably, the slope of the guide rails in the drive means receptacle is initially flat. The slope increases with increasing depth. The inclination in the seat at the separator vessel proceeds in a sequence complementary. At the lowermost first contact point, the trajectory of the guide rail preferably at the removable and securely latched side barrier of the separator vessel has a maximum slope and a decreasing slope towards the end.

The inserted and tilted-back separator vessel is thus always initially positioned in the vertical normal connection direction and only then slid into the limit position of the drive means vessel. Thereby, the U-shaped chute in the drive device container constitutes a storage unit for the separator container. The end side edge of the U-shaped chute and the front side of the separator vessel preferably define the forwardmost engagement position of the separator vessel in the drive device vessel. Preferably, the drive device container has upwardly extending side walls of the chute which, in combination with the complementary wedge shape of the separator container, allow the user to insert the separator container into the drive device container with maximum possible specificity. Self-discovered separator positioning at an end position of the drive means container not directly visible is provided by increased centering of the separator container in depth and execution of the trajectory of the guide rails relative to each other. The handle is preferably designed such that its folding over in the final position results in a latching fastening of the separator container to the drive container.

Preferably, the drive means receptacle has a step button. Preferably, the step button is arranged in the middle of the top. Preferably, the step button is arranged and designed such that the separator vessel is partially lower in the final position than the step button arranged in the middle of the top of the drive device.

In a preferred embodiment, the separator vessel has a guide dome which is connected to the fastening element of the drive means vessel in the final position. The connection is preferably designed as a latch, more preferably as an audible snap-fit latch. Preferably, the guide dome has a rear cylindrical surface and is laterally arranged and slotted. Preferably, the cylindrical surface of the guide dome is supported at the wall of the handle in the contour of the stepped drive container. As the angular position of the handle becomes flatter, the separator container, when it is inserted into the drive device container, moves forward to the air guide of the drive device container to be sealed and below the horizontally acting stop geometry of the drive device container. The lateral securing elements, preferably in the form of snap hooks, are preferably designed such that they lock into the slotted contour of the guide domes when the handle is folded over to reach the final position. Not only does the generally consistent design of the visible upper handhold surface to the separator container show the user the correct final position of the separator container in the drive means container, but the audible latching of the snap connection also indicates this. The latching of the separator container in and/or at the drive means container not only prevents the separator container from falling off during the column threshold test (Pfosten-schwelltest), i.e. the setting of an obstacle to be passed, but also during the inversion of the vacuum cleaner. Thus, the entire cleaner can be rotated through 180 ° without dropping the separator container. The separator container can only be removed from the drive means container by deliberately releasing the handle. By this immediate release mechanism, lifting of the entire cleaner at the handle is inhibited.

Preferably, the handle is supported on a hemisphere. These hemispheres ensure self-centering and dust-tight sealing. Preferably, these hemispheres are connected with a shaft which decreases spherically. The spherically reduced shaft of the connection carries away any dust that may have seeped from the bearing location. This very precise, stable and dust insensitive support enables the separator vessel to be positioned precisely in the drive means vessel.

The separator vessel has a collection area in which the aspirated material is collected. The separator vessel also has a central filter, which is designed as a fine filter. The central filter is preferably the last filtration stage before the air flow generated by the drive means during operation flows to the drive means located in the drive means container.

The separator vessel has a front side, a back side, and a side. When the separator vessel is connected with the drive means vessel, its front side is directed towards the drive means vessel and its rear side is directed away from the drive means vessel. The side portions preferably each have a side baffle. One of the side flaps is preferably firmly mounted in the separator vessel, while the other side flap is preferably constructed so as to be removable. The side dams preferably have additional rails that are complementary to at least a portion of the rails of the drive device containers. Preferably, the separator vessel also has a bottom baffle, by means of which the collection area can be emptied, in which collection area the aspirated material is collected. The separator vessel preferably has an actuating element for opening and stopping the bottom flap. Preferably, the actuating element is arranged at the rear side of the separator vessel and is therefore clearly visible to the user. The still open bottom flap of the separator vessel is preferably automatically closed by insertion into the drive means vessel. During sliding on the lateral guides, the open bottom flap comes into contact with the closed bottom plate of the drive container. Preferably, the bottom flaps have sliding plates which are designed to press the bottom flaps upwards by pressing the carrying handle downwards under the horizontal stop of the drive container in such a way that the actuating element automatically latches onto the visible rear side.

In a preferred embodiment, the vacuum cleaner is configured as a cyclone vacuum cleaner. A cyclone cleaner is understood to be a bagless cleaner in which vortices and any vortices are generated in the incoming airflow, so that the sucked material, such as dirt particles, is forced in a predetermined direction and separated due to centrifugal force. The expression "bagless" is to be understood as meaning that the suction material in the vacuum cleaner is directly collected in the collecting region of the separator vessel without a bag or similar replaceable filter medium arranged in the collecting region for receiving the suction material, so that a user does not remove a bag or the like from the separator vessel in order to empty the suction material from the separator vessel. However, the vacuum cleaner may have one or more filter media which prevent the intake material from reaching the drive.

Preferably, the cleaner is a floor cleaner. The floor cleaner is preferably provided with a cable having a plug. The floor cleaner also preferably has a wheel by means of which a user can move the cleaner over the floor to be cleaned when operating. The drive device container preferably has a further handle, by means of which the vacuum cleaner can be carried.
