Definitions
- the invention relates to a vacuum cleaner, in particular an industrial vacuum cleaner, with a housing which has a housing body and a cover arranged on the housing body, wherein in the housing body there is a dust collection container accessible via the cover, in particular a
- Dust collection bag is arranged.
- the vacuum cleaner has an inlet nozzle that protrudes into the dust collection container.
- the dust collection container In a conventional vacuum cleaner, in order to remove and/or close the dust collection container, it is necessary to pull the dust collection container from the inlet nozzle.
- the dust collection container usually has to be compressed - that is, compressed - which creates an air volume flow with which particles are conveyed out of the dust collection container to the outside. There is a risk that this will contaminate the environment with the particles.
- An object of the invention is to provide a vacuum cleaner in which the risk of contamination with particles discharged from the dust collection container is reduced.
- the inlet nozzle is relative 2 is movably mounted to the housing body and can be moved relative to the housing body either into a working position or a release position, with the inlet connection protruding through an opening in the housing body into the dust collection container in the working position and not into the dust collection container in the release position Dust collection container protrudes, and wherein the inlet socket can be pulled out of the dust collection container by means of a pulling movement relative to the housing body, in order to move the inlet socket from the working position to the release position.
- the inlet socket is movably mounted and can be pulled out of the dust collection container, it is not necessary to compress the dust collection container in order to separate the dust collection container from the inlet socket.
- the dust collection container remains attached to the housing body and/or in the same position relative to the housing body. Consequently, when the dust collection container is separated from the inlet connection, the dust collection container is not necessarily compressed and thus the air volume flow that conveys particles out of the dust collection container to the outside does not necessarily occur. The risk of contamination of the surroundings with the particles from the dust collection container can consequently be reduced.
- the invention also relates to a method for operating the vacuum cleaner, comprising the steps:
- the method is preferably designed to correspond to a further development of the vacuum cleaner.

- the vacuum cleaner 10 also has a
- the suction hose unit 28 via which the vacuum cleaner 10 can suck dust from the outside into the dust collection container 4.
- the suction hose unit 28 includes, for example, a suction hose 29 and the inlet connector 5.
- the suction hose 29 includes, in particular, a flexible and/or elongated hose body 31.
- the inlet connector 5 is arranged at a first end of the suction hose 29.
- the suction hose 29 and the inlet nozzle 5 can each be designed as separate parts that are attached to one another.
- the suction hose 29 can be detachably fastened to the inlet connection piece 5 .
- the inlet socket can also be designed as a section, in particular as an end section, and together with the suction hose 29 can form a single part, in particular a one-piece part.
- one end of the suction hose can be designed as an inlet connector.
- the suction object 16 is connected to a second end of the suction hose 29 . Dust sucked up via the suction object 16 or originating from the suction object 16 is sucked through the suction hose 29 and the inlet connector 5 into the dust collection container 4, in particular the dust collection chamber 27, by the negative pressure generated by the suction unit 23.
- the suction unit 23 During suction, the suction unit 23 generates an air flow 32, which is shown as an example in FIG. 1 as an arrow.

- FIG. 1 shows the inlet connection 5 in the working position and FIG 11
- Inlet port 5 in the release position In the working position, the inlet socket 5 protrudes through the opening 6 into the dust collection container 4. In the release position, the inlet socket does not protrude into the dust collection container 4. By way of example, the inlet connector 5 protrudes further into the receiving space 19 in the working position than in the release position.
- the inlet connector 5 can be pulled out of the dust collection container 4 by a pulling movement 7 relative to the housing body 2 in order to move the inlet connector 5 from the working position to the release position.

- FIGS. 6 and 7 show a variant in which the pull-out movement 7 comprises a pivoting movement or a curved path movement.
- the pull-out movement 7 comprises a pivoting movement or a curved path movement.
- the inlet connector 5 In order to move the inlet connector 5 from the working position to the release position, the inlet connector 5 must be pivoted about an actually existing pivot axis 42 or a virtual pivot axis. Alternatively or additionally, a movement of the inlet connector 5 along a curved path is required in order to move the inlet connector 5 from the working position to the release position. 17
- the vacuum cleaner 10 includes a pivot bearing 41 via which the inlet connector 5 is pivotably mounted relative to the housing body 2 .
- the pivot bearing 41 defines a pivot axis 42 about which the pivoting movement of the inlet port 5 takes place.
- the pivot axis 42 is arranged, for example, below the opening 6 on the front side of the peripheral wall 18 .
- the pivot bearing 41 includes, for example, a coupling element 43 which is attached to the inlet port 5 and which leads to the pivot axis 42 .
- the pivot bearing 41 is purely optional.
- Pivot axis 42 - or, alternatively, a cam track for the cam track movement - is preferably defined by a curvature of bearing section 35 and tube section 39 .
- the curvature of the bearing section 35 and the tube section 39 is such that the movement of the
- Inlet socket 5 relative to the housing body 2 results in a (virtual) pivot axis located below the opening 6 .
- FIGS. 8 and 9 show a variant in which the vacuum cleaner 10 has a stop arrangement 44 .
- the stop arrangement 44 comprises an outer stop 11 which, in the release position, prevents the inlet connection piece 5 from being pulled out further from the opening 6 .
- the outer stop 11 is in particular an end stop. The outer stop 11 thus prevents the inlet connector 5 from being pulled out further in the direction of the pull-out movement 7 in the release position. In particular, the outer stop 11 prevents the inlet connector 5 from being able to be removed from the opening 6 . 18
- the inlet connection piece 5 has a connection piece stop section 45 which, for example, protrudes radially from the inlet connection piece 5 , in particular from the pipe section 39 . In the release position, the connector stop section 45 rests against the outer stop 11 and thus prevents another
- the stop arrangement 44 also has an internal stop 46 which, when the inlet connection piece 5 is in the working position, prevents the inlet connection piece 5 from being pushed further into the housing body 2 . In the working position, the connecting piece stop section 45 rests against the inner stop 46 .
- the path of movement of the inlet connector 5 is thus limited in the direction of the withdrawal movement by the outer stop 11 and in the opposite direction--ie in the direction of the insertion movement--by the inner stop 46.
- the bearing element 34 has a recess 47 into which the connector stop section 45 is inserted and which is delimited by the outer stop 11 and/or the inner stop 46 in the axial direction of the inlet connector 5 .

- the dust collection container 4 has the closure device 12 .
- the closure device 12 is designed to close the inlet opening 14 of the dust collection container 4 exposed by pulling the inlet connection 5 out of the dust collection container 4 .
- the inlet opening 14 is, for example, the only opening of the dust collector 4.
- the inlet connection piece 5 is inserted into the inlet opening 14 and 19 protrudes through the inlet opening 14 from outside the dust collection container 4 into the dust collection container 4 - ie into the dust collection space 27 - inside.
- the closure device 12 can expediently be actuated manually and/or automatically in order to cause the closure device 12 to close the inlet opening 14 .
- the closure device 12 is actuated automatically when the inlet connection piece 5 is pulled out of the dust collection container 4 , so that the closure device 12 automatically closes the inlet opening 14 when the inlet connection piece 5 is pulled out of the dust collection container 4 .
- the closure device 12 includes, for example, a closure element 48 which can be moved either into an open position or into a closed position. In the closed position, the closure element 48 closes the inlet opening 14, in particular completely, and in the open position the closure element 48 releases the inlet opening 14.
- the closure element 48 is embodied as a closure flap, for example.
- the dust collection container 4 comprises a container body 49 to which the closure element 48 is attached, in particular pivotable.
- the closure element 48 is spring-loaded so that it is pushed into the closed position. In the working position, for example, the inlet connector 5 bears against the closure element 48 and thereby presses the closure element 48 into the open position. Due to the pulling-out movement of the inlet connector 5, the closure element 48 is no longer held in the open position by the inlet connector 5 and assumes the closed position, in particular due to a spring force.
- Closure device 12 is automatically actuated by the pull-out movement 7 in this way.
- Closure device 12 can be designed in such a way that the closure device 12 closes the inlet opening 14 in response to manual actuation of the closure device 12 .
- the closure element can be put into the closed position manually by the user, for example by manually pivoting and/or displacing the closure element.
- the closure device is designed as a roller shutter closure.
- the closure device is preferably actuated from outside the housing body 2, in particular manually or automatically.
- a locking mechanism that allows the dust collection container 4 to be locked from outside the housing body 2, for example via kinematics and/or via a mechatronic system.
- the closure device can be actuated in particular from outside the housing body 2 and a kinematics and/or a mechatronic system is expediently present in order to convert an actuation taking place outside of the housing body 2 into a closing of the inlet opening 14 .
- a kinematics and/or a mechatronic system is expediently present in order to convert an actuation taking place outside of the housing body 2 into a closing of the inlet opening 14 .
- there is an actuating unit on the outside of the housing body which is coupled to the closure element via the kinematics and/or the mechatronic system, so that in response to an actuation of the actuating unit by the user via the kinematics and/or the mechatronic system, the the closure element closes the inlet opening 14 .
- the inlet connection 5 can be moved from the working position to the release position, then the dust collection container 4 can be closed (by an external actuation, for example by moving the inlet connection 5 to the release position). and only after the dust collection container 4 has been closed is the lid 3 opened.
- the cover 3 is only opened, in particular removed, when the dust collection container 4 is already closed.
- the inlet socket 5 must be moved, in particular into the release position and/or the removal position, so that the dust collection container 4 can be removed from the housing body 2.
- the inlet nozzle 5 locks the dust collection container 4 in the working position
- the dust collection container 4 cannot be removed from the housing body 2 in the working position of the inlet nozzle.
- the dust collection container 4 can be removed from the housing body 2 in the release position and/or the removal position of the inlet connector 5 .
- the dust collection container 4 can be removed from the housing body 2 by a removal movement that occurs in particular vertically upwards. In the working position, the inlet connector 5 protrudes into the dust collection container 4, in particular in a horizontal direction, and thereby blocks the removal movement required for removing the dust collection container 4.
- FIGS. 13 to 15 show a variant in which the vacuum cleaner 10 has a locking device 15 .
- the locking device 15 is designed as an example 22 to lock the inlet port 5 in the working position.
- the locking device 15 can be designed to lock the inlet connector 5 in the release position.
- the locking device 15 can be placed either in a locked state or in an unlocked state, in particular by manual actuation. In the locked state, the locking device 15 prevents the inlet connector 5 from being moved from the working position to the release position. In the unlocked state, the locking device 15 does not prevent the inlet connector 5 from being moved from the working position to the release position.
- the locking device 15 has a locking element 51 which is in engagement with the inlet connection piece 5 in the locking state and in the
- Unlocked state is not engaged with the inlet port 5.
