Definitions

  • the invention relates to a dust bag removal module and a vacuum cleaner for cleaning and maintaining floor surfaces with a housing, a blower for generating a negative pressure for collecting dust by means of an air flow, wherein the blower is arranged in a blower chamber of the housing, and a dust chamber in the housing connected to the blower chamber for receiving a dust bag for cleaning the absorbed air of dust, wherein the dust chamber is accessible for changing the dust bag via a dust chamber opening that can be covered with a housing cover.
  • the floor surface can be a textile floor covering such as a carpet or rug or a hard floor such as wooden parquet, laminate or PVC floor covering.
  • a dust bag for such a vacuum cleaner today usually comprises a holding plate for fastening in a dust chamber of the vacuum cleaner, with an inlet opening being let into the holding plate for receiving a dust-laden air flow from the vacuum cleaner, with a filter bag made of an air-permeable material that is open to the inlet opening being arranged on the holding plate, with the material of the filter bag being designed to filter the dust out of the air flow as the air flow passes through.
  • the inlet opening let into the holding plate is provided with a flap that closes the dust bag when it is removed from the dust chamber so that dust collected in the filter bag cannot escape again via the inlet opening.
  • the inlet opening is usually provided with a seal that seals the dust bag from an inlet nozzle of the vacuum cleaner that dips into the inlet opening.
  • the US 2005 098039 A1 discloses a dust bag removal module with a first coupling point for connection to a vacuum cleaner and a second coupling point for connection to a dust bag, wherein the dust bag removal module has a gripping surface and an ejection mechanism for separating the dust bag.
  • the EN 10 2019 123150 A1 discloses a dust bag with a holding plate on which a pull tab is arranged.
  • the DE 29 821 276 U1 discloses a dust bag with a holding plate to which a holding bracket is attached.
  • the invention therefore addresses the problem of providing a solution that enables simpler, more sustainable and resource-saving operation of a vacuum cleaner.
  • the amount of waste generated when changing the dust bag should be reduced 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, wherein the dust bag removal module has a first, multiply separable and connectable coupling interface for separation and connection to the vacuum cleaner and a second, multiply separable and connectable coupling interface for separation and connection to a dust bag, wherein the dust bag removal module has a gripping surface for manually grasping 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 separating 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 because the amount of waste can be reduced by changing the dust bag.
  • the dust bag removal module simplifies the manual arrangement and removal of a dust bag in a vacuum cleaner by a user. For this purpose, the user can easily handle the dust bag removal module using the handle surface.
  • the first, multiple separable and connectable coupling interface of the dust bag removal module enables the device to be disconnected 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, multiple separable and connectable coupling interface when a new dust bag is inserted into the vacuum cleaner with the dust bag removal module.
  • the dust bag removal module also has the second coupling interface for previously connecting the dust bag to the dust bag removal module.
  • a decoupling device is provided on the dust bag removal module that enables the connection between the full dust bag and the Dust bag removal module on the second coupling interface. Thanks to the multiple detachable and connectable coupling interfaces of the dust bag removal module, it can be used multiple times when changing the dust bag and does not need to be replaced. It secures the dust bag sufficiently in the dust compartment of the vacuum cleaner so that a complex holding plate that is replaced with the dust bag is not necessary. This reduces the complexity of the dust bag and the waste generated when changing the dust bag, thus saving valuable resources in a simple way.
  • the full dust bag can be very easily lifted out of the dust compartment using the handle on the dust bag removal module and an empty bag can be easily inserted into the dust compartment of the vacuum cleaner by the user using the handle on the dust bag removal module.
  • the second coupling interface is designed to create a locking connection to a dust bag, wherein the decoupling device is designed to separate this locking connection to the dust bag.
  • the locking connection can be used to create a particularly simple coupling interface between the dust bag and the dust bag removal module that can be separated or connected multiple times.
  • the locking 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 trash can, the dust bag released from the second coupling interface can fall from the dust bag removal module into the trash can. The user can therefore handle the dust bag via the dust bag removal module and does not have to touch the dust bag directly for disposal.

  • 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 dust-laden air flow of the coupled vacuum cleaner can be particularly easily the dust bag removal module into the coupled dust bag.
  • the air duct advantageously forms a straight, tubular nozzle between the vacuum cleaner and the dust bag.
  • At least one flap is arranged in the air duct, wherein the at least one flap is designed 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.
  • the inlet opening of the dust bag can be closed via the flap in the dust bag removal module during handling of the dust bag removal module and storage of the switched off vacuum cleaner, so that no dirt escapes from the coupled dust bag via the air duct of the dust bag removal module.
  • the vacuum cleaner applies a differential pressure to the flap when generating the air flow, 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 designed to be moved by the differential pressure against the spring force of a spring into the open position, wherein the flap is further designed to be automatically moved back into a closed position to close the air duct by the spring force of the spring.
  • the flap in the air duct is subjected to the spring force of a spring, which moves the flap from the open position back into the closed position as soon as the air flow of the vacuum cleaner stops, for example when the fan is switched off.
  • the dust bag removal module has a seal for sealing against a coupled dust bag.
  • the dust bag removal module By sealing the dust bag removal module against the dust bag, it is possible to prevent the air flow from the air duct of the dust bag removal module from flowing past the inlet opening of the dust bag. Since the seal is attached to the dust bag removal module, the dust bag can be replaced without replacing the seal, which reduces the waste generated for the change.
  • 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 replaced when the dust bag is changed. This can prevent the seal from failing over the service life of the vacuum cleaner. With the fixed arrangement of the seal on the dust bag removal module, the seal can also be simply replaced by by replacing the relatively simple dust bag removal module.
  • a particularly advantageous embodiment is one in which the dust bag removal module has a seal for sealing against a coupled vacuum cleaner.

  • the user can, for example, handle a handle of the vacuum cleaner connected to the suction pipe.
  • the suction mouth of the floor nozzle is elongated and runs essentially transversely to the processing direction.
  • elongated means that the preferably essentially rectangular suction mouth has a greater length transversely to the processing direction than its width in the processing direction.
