Definitions

  • Vacuum cleaner with a collecting container in which different areas can be separated off as well as a method for replacing a disposal bag in a vacuum cleaner
  • the present invention relates to a vacuum cleaner with a separator for separating dirt particles from an air flow sucked in by the vacuum cleaner, wherein the separator comprises at least one first separator and a second separator and in a basic collector of the vacuum cleaner under different areas of the basic collector with a partition are separable from each other.
  • the invention relates to a method for replacing an Ent care bag in a vacuum cleaner.
  • the vacuum cleaner usually contains a filter to hold back dust and dirt particles that get into the interior of the vacuum cleaner from the sucked in air. Without a filter, the sucked in dust or the sucked in dirt particles could damage the turbine, which is used to generate a negative pressure inside the vacuum cleaner, and / or the sensitive electronics of the vacuum cleaner, which is used to control, regulate and monitor the vacuum cleaner .
  • the sucked-in dust and the sucked-in dirt particles settle in the pores of the filter.
  • the accumulation of dust and dirt particles causes the filter to become so clogged after a certain period of time that the filter is no longer effective.
  • a separator can be used in the vacuum cleaner.
  • the separator is used to separate dirt particles that are in the sucked in air and is accordingly accordingly positioned in the vacuum cleaner that a large part of the sucked in dirt particles have already been removed from the air before the air flows through the filter.
  • Vacuum cleaning devices with a separate separating device are already available on the market.
  • vacuum cleaning devices are known in the prior art which have more than one separation stage. What is meant by this is that such vacuum cleaner devices often include means with which different dust particles can be filtered out of the air flow sucked in by the vacuum cleaner device at different points in the vacuum cleaner device. Usually, different sized dust or dirt particles are filtered out at the different separation stages.
  • the problem with such conventional vacuum cleaning devices with different separation stages, which are known from the prior art, is that these vacuum cleaning devices usually have one collecting container per separation stage. As a result, as many collecting containers as there are separation stages must be provided in the vacuum cleaner device.
  • a closable disposal sack or disposal bag In order to ensure dust-free disposal, as is required, for example, for safety vacuum cleaners of performance class M or higher, a closable disposal sack or disposal bag must be used for each collection container. Thus it is necessary to use as many disposal bags as there are separation stages. In particular, it would be desirable that the number of collection containers could be reduced and that fewer disposal bags could be used as separation stages.
  • the object of the present invention is therefore to overcome the disadvantages of conventional vacuum cleaning devices described above and to provide a vacuum cleaning device that manages with a common disposal bag, although the vacuum device provides several separation stages. It would furthermore be desirable if a vacuum cleaning device could be provided in which the areas in which the different dust and dirt particle subsets are stored are separated from one another in such a way that no air or pressure equalization flows occur between the areas and that the subsets in the Are separated from each other essentially without dust.

  • Advantageous embodiments of the subject matter of the independent claim can be found in the dependent claims.
  • the object is achieved by a vacuum cleaner with a separator for separating dirt particles from an air stream sucked in by the vacuum cleaner, the separator comprising at least one first separator and one second separator.
  • the vacuum cleaner is characterized in that the vacuum cleaner comprises a basic collecting container into which a disposal bag can be inserted, different areas of the basic collecting container being separable from one another with a partition and the different areas of the basic collecting container each being assigned to a separator can be, wherein the partition wall comprises an elastic seal, which is set up to seal the different areas of the base collecting container dust-free against each other.
  • a vacuum cleaning device with a separation device comprising at least a first separation stage and a second separation stage.
  • the first separator is assigned to the first separating stage and the second separator is assigned to the second separating stage.
  • different areas of the basic collection container can be separated with a partition, the partition comprising an elastic seal which is set up to press the disposal bag against a bottom of the basic collection container when it is inserted, the different areas of the basic collection container being dust-free are lockable against each other.
  • the proposed vacuum cleaning device preferably has a collecting container with an integrated division depending on the number of particle separation stages used.
  • the number of areas of the basic collection container corresponds to the number of separation stages.
  • the term “separation stage” preferably means that particles are filtered out of the air flow at different points. This filtering out is preferably carried out by separators, which together form the separating device of the vacuum cleaner.
  • separators which together form the separating device of the vacuum cleaner.
  • the filtering takes place according to other criteria or properties, such as, for example, electrical properties.
  • similar, identical or different separators for separating the particles from the air stream can be used in the vacuum cleaner, which then jointly separate the separators. form device.

  • a major advantage of the invention is that by providing the seal the partition between the different areas of the base collecting container, the usual pressure equalization flow between the separators from the vacuum cleaner or the associated collecting containers is avoided.
  • the invention leads to the fact that essentially no backflow forms between the separators from the first separator to the second separator, such a backflow would impair the functioning of the proposed vacuum cleaner and reduce the suction and separation performance of the vacuum cleaner.
  • dirty particles is used synonymously with the term “dust particles”.
  • the terms preferably include solid and / or solid particles which are preferably present in an air stream, ie in a gas or a gas mixture, which is preferably generated by a negative pressure generated by the vacuum cleaner device.
  • air is not an unclear term for the specialist, because the specialist knows that it denotes a gas mixture that consists of almost 80% nitrogen (N 2 ), approx. 20% oxygen (0 2 ) and a small amount Proportions of other gases or gas mixtures.
  • a particular advantage of the invention is that only a single collecting container in the form of the basic collecting container has to be provided in the proposed Staubsaugvor direction.
  • the vacuum cleaner can be carried out in a particularly compact and space-saving manner.
  • only one disposal bag is required, since this is advantageously used or laid out in the entire basic collection container.
  • individual areas in the interior of the base collection container are preferably separated off, so that individual areas for the different dust and dirt particle subsets of the various separation stages are preferably also formed inside the disposal bag.
  • the partial quantities of dirt are obtained from the different separation stages, with both separators in the first separator For example, a first partial amount of dirt and, for example, a second partial amount of dirt is separated in the second separator.
  • the provision of the sealing partition advantageously eliminates the need to provide an additional, costly port for receiving or replacing the disposal bag, as is customary in conventional vacuum cleaning devices. Since only one disposal bag has to be used in the context of the present invention, the provision of an integrated hose connection opening can also be dispensed with in the proposed vacuum cleaning device, so that the device can be made particularly simple and low-maintenance. In particular, simple plastic bags can be used to hold the dust, so that the operating costs for the vacuum cleaner can be reduced by the invention. It was surprising for the professional world that a vacuum cleaner can be provided which, regardless of the number of deduster stages used, manages with just one disposal bag and / or collection container, although dirt is filtered out of the air flow in the vacuum cleaner in at least two separation stages.

Due to the additional support of the disposal bag on the bottom of the basic collection container, the disposal bag is advantageously stabilized and the bag is effectively prevented from sticking to or sucking into one of the filters of the vacuum cleaner.
