Definitions

  • the invention relates to a dust bag removal module and a vacuum cleaner for cleaning and caring for floor surfaces with a housing, a fan for generating a negative pressure for taking up dust by means of an air flow, the fan being arranged in a fan compartment of the housing, and a dust compartment connected to the fan compartment in the housing for accommodating a dust bag for cleaning dust from the air taken in, the dust compartment being accessible for changing the dust bag via a dust compartment opening which can be covered with a housing cover.
  • vacuum cleaners are used to clean surfaces such as textile floor coverings and smooth floors.
  • the floor surface can be covered by a textile floor covering such as a rug or carpeting or by a hard floor such as e.g. B. a wooden parquet, laminate or PVC flooring can be formed.
  • a dust bag for such a vacuum cleaner today usually includes a holding plate for attachment in a dust compartment of the vacuum cleaner, with an inlet opening for receiving a dust-laden air flow of the vacuum cleaner being embedded in the holding plate, with a filter bag made of an air-permeable material open to the inlet opening on the holding plate is arranged, wherein the material of the filter bag is designed to filter the dust from the air flow when the air flow passes through.
  • the inlet opening embedded in the holding plate is provided with a flap, which closes the dust bag when it is removed from the dust compartment, so that dust collected in the filter bag cannot escape through the inlet opening.
  • the inlet opening is regularly provided with a seal which seals the dust bag from an inlet connection piece of the vacuum cleaner that dips into the inlet opening.
  • the invention therefore faces the problem of specifying a solution with which simpler, more sustainable and resource-saving operation of a vacuum cleaner is possible.
  • the amount of waste should be reduced by changing the dust bag and handling when changing the dust bag should be simplified.
  • the dust bag removal module for manual arrangement in a vacuum cleaner and for manual removal from the vacuum cleaner, the dust bag removal module having a first, multiple disconnectable and connectable coupling interface for disconnecting and connecting to the vacuum cleaner and a second, multiple disconnectable and connectable coupling interface for disconnecting and connecting with a dust bag, wherein the dust bag removal module has a gripping surface for manually gripping the dust bag removal module when removing and separating the first coupling interface from the vacuum cleaner and when arranging and connecting the first coupling interface to the vacuum cleaner, and wherein the dust bag removal module has a decoupling device for manually disconnecting the connection to the dust bag at the second coupling interface, handling when changing the dust bag can be simplified and at the same time resources can be saved, since the amount of waste can be reduced by changing the dust bag.
  • the dust bag removal module simplifies the manual placement and removal of a dust bag in a vacuum cleaner by a user. For this purpose, the dust bag removal module can be easily handled by the user on the gripping surface.
  • the first coupling interface of the dust bag removal module that can be disconnected and connected multiple times enables the vacuum cleaner to be separated from the vacuum cleaner when the dust bag is removed via the dust bag removal module.
  • the connection of the dust bag removal module to the vacuum cleaner can also be established very easily via the first coupling interface that can be disconnected and connected multiple times when a new dust bag with the dust bag removal module is inserted into the vacuum cleaner.
  • the dust bag extraction module also has the second pairing interface to connect the dust bag to the dust bag extraction module in advance.
  • a decoupling device is provided on the dust bag removal module that allows manual disconnection of the connection between the full dust bag and the dust bag removal module at the second coupling interface. Thanks to the coupling interfaces of the dust bag removal module that can be disconnected and connected several times, it can be used several times when changing the dust bag and does not have to be replaced. It secures the dust bag in the dust chamber of the vacuum cleaner sufficiently so that there is no need for a costly holding plate that is exchanged with the dust bag. This reduces the complexity of the dust bag and the waste generated when changing the dust bag, so that valuable resources are easily saved. When changing, the full dust bag can be lifted out of the dust compartment very easily using the grip surface of the dust bag removal module, and an empty bag can be removed simply inserted by the user into the dust chamber of the vacuum cleaner using the grip surface of the dust bag removal module.
  • the second coupling interface is set up to produce a latching connection to a dust bag, with the decoupling device being set up to separate this latching connection to the dust bag.
  • a particularly simple coupling interface between the dust bag and the dust bag removal module that can be disconnected or connected multiple times can be created via the snap-in connection.
  • the snap-in connection can also be easily separated by the user, so that the dust bag can be disengaged from the second coupling interface and disposed of separately from the dust bag removal module.
  • the decoupling device for example over a rubbish bin, the dust bag released from the second coupling interface can fall from the dust bag removal module into the rubbish bin. Therefore, the user can handle the dust bag via the dust bag removal module and does not have to directly touch the dust bag for disposal.
  • a bayonet catch or the like can also be provided on the second coupling interface.
  • the dust bag removal module has an air duct for guiding an air flow from a coupled vacuum cleaner into a coupled dust bag.
  • the air duct advantageously forms a straight, tubular connection piece between the vacuum cleaner and the dust bag.
  • a particularly advantageous embodiment of the invention relates to the fact that at least one flap is arranged in the air duct, with the at least one flap being set up to be moved through the air duct into an open position by a differential pressure applied to the flap for the air flow of the coupled vacuum cleaner become.
  • the flap in the dust bag removal module allows the dust bag inlet opening to be closed during handling of the dust bag removal module and storage of the dust bag be closed when the vacuum cleaner is switched off, so that no dirt escapes from the coupled dust bag via the air duct of the dust bag removal module.
  • the flap is opened so that the air flow can flow through the air duct of the dust bag removal module.
  • a particularly advantageous embodiment of the invention therefore provides that the flap is set up to be moved by the differential pressure against the spring force of a spring into the open position, with the flap also being set up to automatically return to a closed position for the closed position by the spring force of the spring Closing the air duct to be moved.
  • the flap in the air duct is subjected to the spring force of a spring, which moves the flap from the open position back to the closed position as soon as the air flow of the vacuum cleaner is interrupted, for example by switching off the fan breaks off.
  • the dust bag removal module has a seal for sealing against a coupled dust bag.
  • the sealing of the dust bag removal module relative to the dust bag can prevent the air flow from the air duct of the dust bag removal module from flowing past the inlet opening of the dust bag. Because the gasket is attached to the dust bag extraction module, the dust bag can be replaced without replacing the gasket, reducing the waste associated with replacement.
  • the seal between the dust bag and the dust bag removal module can also be fixed to the inlet opening of the dust bag, so that the seal is renewed when the dust bag is changed. This can prevent seal failure over the life of the vacuum cleaner. With the fixed arrangement of the seal on the dust bag removal module, however, the seal can also be renewed simply by exchanging the relatively simply constructed dust bag removal module.
  • An embodiment that provides that the dust bag removal module has a seal for sealing against a coupled vacuum cleaner is particularly advantageous.
  • the sealing of the dust bag removal module relative to the vacuum cleaner can prevent the air flow from flowing past the air duct of the dust bag removal module. Since the seal is attached to the dust bag removal module, the seal can be renewed simply by replacing the relatively simple dust bag removal module.
  • the vacuum cleaner according to the invention which has already been described above and in more detail below, is characterized by a coupling receiving interface for receiving a dust bag removal module already described above and in more detail below, with a dust bag received in the dust chamber being coupled in the dust chamber via a dust bag removal module received at the coupling receiving interface.
  • the coupling receiving interface fixes the dust bag extraction module in the dust compartment of the vacuum cleaner very easily.
  • the dust bag coupled to the dust bag removal module can thus be safely positioned in the dust compartment. This makes it easy to change the dust bag on this vacuum cleaner.
  • the dust bag removal module can be securely positioned in the dust chamber to receive the dust bag coupled to the dust bag removal module.
  • the vacuum cleaner has a blower for generating a negative pressure, through which a floor nozzle guided over a floor surface to be cleaned picks up dust and dirt from the floor surface.
  • a blower for generating a negative pressure
  • the user moves the floor nozzle back and forth in the working direction by means of pushing and pulling movements.
  • the floor nozzle slides over the floor surface to be cleaned.
  • the underside of the floor nozzle slides over the carpet, while in the case of smooth floors the underside floats over these floor surfaces at a distance, possibly using spacer bristles.
  • the user can, for example, manipulate a vacuum cleaner handle connected to the suction pipe.
  • the suction mouth of the floor nozzle is elongate and runs essentially transversely to the working direction.
  • Elongated in this context means that the preferably substantially rectangular suction mouth has a greater length transverse to the processing direction than width in the processing direction.
  • the suction mouth is preferably between 20 and 30 cm long transversely to the processing direction.
  • the vacuum cleaner can also be designed as an independently moving vacuum cleaner, in particular a vacuum robot, so that the working direction of the floor nozzle corresponds to the direction of travel of the independently moving vacuum cleaner.
  • An advantageous embodiment of the vacuum cleaner provides that the first coupling interface of a recorded dust bag removal module is coupled to the coupling receiving interface of the vacuum cleaner and that the second coupling interface of the recorded dust bag removal module is coupled to a dust bag accommodated in the dust chamber.
  • the dust bag can be removed very easily via the two coupling interfaces of the dust bag removal module and safely placed in the dust compartment of the vacuum cleaner.
  • the multiple disconnectable and connectable coupling interfaces allow the intermediate dust bag removal module to be reused when replacing the dust bag in the vacuum cleaner.
  • the vacuum cleaner has a funnel-shaped threading slope on the housing cover, into which the dust bag removal module dips when the housing cover is closed.
  • the funnel-shaped threading bevel makes it very easy to ensure that the dust bag removal module is optimally positioned in the dust compartment of the vacuum cleaner after the housing cover is closed, and the dust bag coupled to the dust bag removal module is thus optimally positioned in the dust compartment.
  • FIG 1 denoted by the reference numeral 2 is a vacuum cleaner with floor nozzle 19 is shown purely schematically.

  • dirt and grime are picked up from the floor surface B to be cleaned by an air flow via the suction mouth of the floor nozzle 19 and transported away via the suction tube 21 and the suction hose 24 into the housing 15 of the vacuum cleaner 2 .
  • a separating system which is designed as a dust bag 5 , is provided in this housing 15 .
  • This separation system 5 is located in a dust chamber formed by the housing parts 13, 15 of the vacuum cleaner 2.
  • This dust chamber 14 is shown open and accessible through a folding mechanism between the vacuum cleaner housing 13 and the housing cover 15 so that the dust bag 5 is visible and removable.
  • the dust chamber 14 is closed and a negative pressure is generated.
  • the air flow generated by the negative pressure is freed from dirt and grime in the separating system 5 and guided out of the vacuum cleaner 2 via an exhaust air grille 26 .

  • the pedal circuit 27 usually also has a switch for actuating the automatic winding mechanism (not shown) for the connection cable 25 integrated in the vacuum cleaner housing 13 .
  • On the handle 23 there is also a secondary air regulator 28 with which the air flow at the floor nozzle can be interrupted if an object was accidentally sucked in with the floor nozzle.
  • the floor nozzle 19 slides over the floor surface B to be cleaned.
  • the underside of the floor nozzle 19 slides over the floor surface B, while the underside floats over these floor surfaces B at a distance from hard floors, possibly by spacer bristles.

  • the holding plate 31 is permanently connected to the dust bag 5 .
  • the dust bag removal module 1 is used for the manual arrangement of dust bags 5 ( figure 1 ) in a vacuum cleaner 2 ( 1 ) and for manual removal of dust bags 5 ( 1 ) from the vacuum cleaner 2 ( 1 ).
  • the dust bag removal module 1 shown has a first, multiple disconnectable and connectable coupling interface 3 for disconnecting and connecting to the vacuum cleaner 2 ( 1 ).
  • This nozzle-shaped coupling interface 3 of the dust bag removal module 1 is used to connect to the connection opening 32 for the suction hose 24 ( 1 ) in the housing cover 15 of the vacuum cleaner 2.
  • the vacuum cleaner 3 has a coupling receiving interface 17, which is arranged in the housing cover 15 of the vacuum cleaner 2 in the exemplary embodiment.

  • the coupling receiving interface 17 has a funnel-shaped threading slope 18 on the housing cover 15, into which the dust bag removal module 1 when the housing cover 15 is closed, as in figure 2 to see, immerse.
  • the dust bag removal module 1 has a gripping surface 6 for manually gripping the dust bag removal module 1 when removing it and when separating the first coupling interface 3 from the vacuum cleaner 2 ( 1 ) on. This gripping surface 6 is also used for manual gripping of the dust bag removal module 1 by the user when arranging and connecting the first coupling interface 3 to the vacuum cleaner 2 ( 1 ).
  • the dust bag removal module 1 also has a decoupling device 7 for manually disconnecting the connection to the dust bag 5 at the second coupling interface 4. This decoupling device 7 is designed as two opposing levers that the user can manually actuate with a thumb and a finger leave to disconnect the connection between the dust bag 5 and the dust bag removal module 1 at the second coupling interface 4.
  • the second coupling interface 4 can produce a snap-in connection 30 to the dust bag 5 , the simply designed holding plate 31 of the dust bag 5 being snapped to an undercut 36 of the holding plate 31 at the second coupling interface 4 .
  • the decoupling device 7 is set up to close this latching connection 30 separate from the dust bag 5.
  • the levers rotate about the pivot point 35 and thus release the dust bag 5 at the second coupling interface 4 .
  • the locking connection 30 can advantageously be separated over a dustbin, so that the dust bag 5 initially hanging over the dustbin on the dust bag removal module 1 simply falls into the dustbin. The user does not have to touch the full dust bag 5 even when it is disposed of.
  • the gripping surface 6 which is arranged on the dust bag removal module 1 and which enables easy handling of the dust bag removal module 1 serves for this purpose.
  • the dust bag removal module 1 has a preferably tubular air duct 8 for guiding an air flow from the suction hose 24 of the coupled vacuum cleaner 2 into the coupled dust bag 5 .
  • the figure 2 shows a cross section through the dust bag removal module 1 arranged in the vacuum cleaner 2, is in figure 3 a longitudinal section rotated by ninety degrees through the dust bag removal module 1 is shown.
  • the figure 3 1 shows a ninety-degree angle around the drawn-in central axis 33 of the dust bag removal module 2 compared to the illustration in FIG figure 2 rotated section view. It is easier to see in this representation that a two-part flap 9 is arranged in the air duct 8 .
  • the flap parts of the flap 9 are attached to the air duct 8 so that they can pivot. In the pivoted position shown here, the two-part flap 9 closes the air duct 8 of the dust bag removal module 1. This ensures that the flap 9 in the closed position shown retains the dust in the filter bag of the full dust bag 5 when changing, i.e. when handling the dust bag removal module 1.
  • figure 4 is a similar sectional view as in figure 3 shown, but here the two-piece flap has been moved to an open position.
  • the flap 9 is set up to be moved through the air duct 8 into an open position by a differential pressure applied to the flap 9 for the air flow of the coupled vacuum cleaner 2 .
  • the dust bag 5 is thus also closed when there are breaks in vacuuming.
  • the figure 4 shows, however, the open position of the flap 8, which is reached when the vacuum cleaner 2 ( 1 ), especially the fan of the vacuum cleaner 2 ( 1 ), are in operation and an air flow is generated through the coupled dust bag 5.
  • the flap 9 is advantageously set up to be moved by the differential pressure against the spring force of a spring 10 into the open position.
  • the flap 9 is set up in such a way that the spring force of the spring 10 automatically returns the flap 9 to the in figure 3 Closing position shown for closing the air duct 8 emotional. This automatically closes the air duct 8 of the dust bag removal module 1 as soon as the fan of the coupled vacuum cleaner 2 ( 1 ) is switched off and the air flow through the coupled dust bag 5 stops. This can effectively prevent dust from escaping from a full dust bag 5 via the air duct 8 of the coupled dust bag removal module 1 when the bag is changed.
  • the gasket 11 is attached to the dust bag extraction module 1, therefore the dust bag 5 can be replaced without replacing the gasket 11, reducing waste for replacement. Due to the fixed arrangement of the seal 11 on the dust bag removal module 1, the seal 11 can also be replaced simply by replacing the relatively simply constructed dust bag removal module 1.
  • the seal 11 can also be replaced simply by replacing the relatively simply constructed dust bag removal module 1.
  • This second seal 12 on the dust bag removal module 1 is used to seal against the coupled vacuum cleaner 2 ( 1 ). With the sealing of the dust bag removal module 1 against the vacuum cleaner 2 ( 1 ) the air flow can be prevented from flowing past the air duct 8 of the dust bag removal module 1.
  • the seal 12 on the dust bag removal module 1 can easily be replaced by replacing the relatively simply constructed dust bag removal module 1 .
  • the dust bag removal module 1 is used in such a way that the open, semi-circular flap parts of the according figure 4 open flap 9 in the air duct 8 can be seen well. In the closed position, the flap parts of the flap 9 completely close the tubular air duct 8 .
  • FIG 6 an embodiment of the dust bag removal module 1 is shown, which differs from the embodiment according to FIG Figures 2 to 5 differs in that the flap 9 is made in one piece here. In the closed position, the circular flap 9 completely closes the tubular air duct 8 . This one-piece flap 9 is only suspended on one side in the air duct 8, so that only one suspension and one spring 10 are required to move the flap 9 into the closed position.
  • the execution according to figure 7 differs from the statements according to the Figures 2 to 6 of the dust bag removal module 1 in particular in that the snap-in connection 30 engages the retaining plate 31 of the dust bag 5 from the outside.
  • the undercut 36 on the holding plate 31 is accessible here from the outside and the levers of the decoupling device 7 rotate about the pivot point 35 when actuated and thus release the dust bag 5 at the second coupling interface 4 .
  • FIG 8 1 is again an exemplary embodiment of the dust bag removal module 1, which in turn has a latching connection 30 which engages from the inside at the inlet opening 34 of the holding plate 31 of the dust bag 5 into the undercut 36 formed here.
  • the levers of the decoupling device 7 When the levers of the decoupling device 7 are actuated, they rotate about the pivot point 35 and thus release the holding plate 31 of the dust bag 5 at the second coupling interface 4 of the dust bag removal module 1 .
  • FIG 9 a variant of the dust bag removal module 1 is shown, which does not require a locking connection.
  • the dust bag removal module 1 is simply plugged into the inlet opening 34 at the second coupling interface 4 for coupling to the retaining plate 31 of the dust bag 5 .
  • the design of the dust bag removal module 1 according to figure 10 differs from the execution according to figure 9 in particular in that a one-piece flap 9 is provided in the air duct 8 instead of a two-part flap.
  • FIG 11 is again an example of the dust bag removal module 1 shown, which, however, has a latching connection 30 which engages from the outside on the holding plate 31 of the dust bag 5 in the undercut 36 formed here.
  • the levers of the decoupling device 7 When the levers of the decoupling device 7 are actuated, they rotate about the pivot point 35 and thus release the holding plate 31 of the dust bag 5 at the second coupling interface 4 of the dust bag removal module 1 .
  • the circular, open flap 9 in the air duct 8 of the dust bag removal module 1 can also be seen here.
  • the retaining plate 31 of the dust bag 5 at the inlet opening 34 no longer needs to be constructed in such a complex manner as is still the case today.
  • a border of the inlet opening 34 that forms a sufficiently large undercut 36 is sufficient so that the dust bag 5 can be coupled to the dust bag removal module 1 at the second coupling interface 4 .
  • the described invention makes it possible to produce the entire dust bag 5 including the simple retaining plate 31 from a single material.
  • a PP-based non-woven fabric for the filter bag with a simple retaining plate 31 also conceivable from PP.
