Definitions

  • the present invention relates to a vacuum cleaner with a separator for separating dirt particles from an air stream sucked in by the vacuum cleaner, wherein the separator comprises at least a first separator and a second separator and in a basic collecting container of the vacuum cleaner different areas of the basic collecting container with a partition are separable from each other.
  • the invention relates to a method for replacing a disposal bag in a vacuum cleaner.
  • a vacuum cleaner or a vacuum cleaner is used in combination with the machine tool in order to suck in the blown dust.
  • 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 In order to protect the filter of a vacuum cleaner from an excessive amount of sucked-in dust and dirt particles and to increase the useful life of the filter, 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 Positioned in the vacuum cleaner so that a large part of the sucked in dirt particles are already removed from the air before the air flows through the filter. By separating a large part of the dirt particles with the help of the separator, the useful life of the filter can be increased.
  • 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 cleaning devices often comprise means with which different dust particles can be filtered out of the air flow sucked in by the vacuum cleaning device at different points in the vacuum cleaning device.
  • 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 cleaning device.
  • 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 which manages with a common disposal bag, although the vacuum cleaning 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 so separated from one another that no air or pressure equalization flows occur between the areas and that the subsets are essentially dust-free are separated from each other.
  • 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 cleaning device is characterized in that the vacuum cleaning device comprises a basic collecting container into which a disposal bag can be inserted, different areas of the basic collecting container can be separated from one another with a partition and the different areas of the basic collecting container can each be assigned to a separator , wherein the partition wall comprises an elastic seal, which is designed to seal the different areas of the base collecting container from one another in a dust-free manner.
  • a vacuum cleaner 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 designed 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 against each other without dust are lockable.
  • 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.
  • this preferably means that, for example, the partition wall in the basic collecting container forms two separate areas if two separation stages are provided with the vacuum cleaner.
  • the term “separation stage” preferably means that particles are filtered out of the air stream 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 can be used in the vacuum cleaner for separating the particles from the air stream, which then jointly form the separator form.
  • the vacuum cleaner comprises, for example, two separation stages, it is preferred within the meaning of the invention that the interior of the basic collection container can be separated into two individual areas, with those dust particles being collected in a first area of the basic collection container that were collected with the first separator are filtered out of the air flow caused by negative pressure, and those dust particles are collected in a second area of the basic collecting container, which are filtered out of the air flow caused by negative pressure with the second separator.
  • An essential advantage of the invention is that the provision of the sealing partition between the different areas of the basic collecting container avoids the pressure equalization flow between the separators or the associated collecting containers that usually occurs in vacuum cleaning devices.
  • 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 that 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 person skilled in the art because the person skilled in the art knows that it denotes a gas mixture that consists of almost 80% nitrogen (N 2 ), approx. 20% oxygen (O 2 ) and small proportions 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 vacuum cleaning device.
  • the vacuum cleaner can be designed to be particularly compact and space-saving.
  • 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 basic collecting container are preferably separated off, so that individual areas for the different partial quantities of dust and dirt particles of the various separation stages are preferably also formed in the interior of the disposal bag.
  • the partial amounts of dirt are preferably obtained from the different separation stages, for example in the first separator 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 makes it possible to dispense with the provision of an additional, cost-intensive 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 designed in a particularly simple and low-maintenance manner. In particular, simple plastic bags can be used to hold the dust, so that the operating costs for the vacuum cleaner device can be reduced by the invention. It was surprising to the experts that a vacuum cleaner can be provided that manages with just one disposal bag and / or collecting container regardless of the number of deduster stages used, although dirt is filtered out of the air flow in the vacuum cleaner in at least two separation stages.
  • the disposal bag can be pressed against the bottom of the basic collection container with the partition wall, the disposal bag is advantageously supported on the container bottom when a disposal bag is inserted in the basic collection container. In the context of the invention, this state is preferably referred to as the "insertion case".
  • the additional support of the disposal bag on the bottom of the basic collection container advantageously stabilizes the disposal bag and effectively prevents the bag from sticking or being sucked into one of the filters of the vacuum cleaner.
  • the invention enables an essentially dust-free disposal of the dust and dirt particles filtered out from the vacuum cleaner, without a flap for the hose connection having to be closed.
  • the separators are connected in series.
  • this preferably means that the separators can preferably be arranged next to one another in the suction head of the vacuum cleaning device and in particular are flowed through one after the other by the air or suction flow of the vacuum cleaning device.
  • the air flow first flows through the first and then the second separator, with different subsets of dust or dirt particles being filtered out of the suction flow in the different separators will.
  • different sized dust or dirt particles can be filtered out at the different separation stages, ie the different filter stages are preferably set up to filter the dust according to different particle sizes or to filter out the differently sized dirt particles at different points in the vacuum cleaner when the individual separation stages are activated are arranged at different points in the vacuum cleaner.
  • the vacuum cleaner device in a suction head comprises a vacuum cleaner hose connection for the flow of a suction stream, the first separator in particular being set up for the suction stream to flow through.
  • the air stream flows through the first separator through a vacuum cleaner hose connection in the suction head.
  • an undesired backflow from the second into the first separator is advantageously avoided, this advantage being achieved in particular through the separation of the different areas with the elastic seal.
  • the elastic seal is preferably designed to close the different areas in the basic collecting container against each other in a dust-free and flow-free manner.
  • this preferably means that essentially no dust is exchanged between the areas of the basic collecting container or that no air or equalization flows flow between the areas of the basic collecting container.
  • air or equalizing flows would occur, for example, if a dividing wall does not have an elastic seal at the bottom, because a gap can then form between the dividing wall and a bottom surface of the basic collecting container, through which an undesired gas and material exchange can occur.
  • the elastic seal comprises sealing lips or a sealing ring or is designed as sealing lips or sealing ring.
  • the elastic seal preferably forms a lower area of the partition or a connection between the partition and a bottom surface of the basic collecting container. Due to the preferred elastic design of the seal, the elastic formation adapts to the spatial conditions in the basic collecting container and seals any gap between the partition wall and the bottom surface of the basic collecting container particularly effectively, so that the undesired gas and material exchange between the different areas in the basic collecting container, which are preferably assigned to the different separators, is avoided particularly effectively.
  • the partition is integrated on a suction head. This integrated design means that no additional component is required that could possibly be lost or forgotten.
  • the partition is a component of the suction head of the vacuum cleaning device and can be lifted off or removed with it.
  • one of the separators is formed by a collecting container for receiving dirt particles, a filter element for receiving dirt particles or a cyclone separator.
  • the separator can in particular also be formed by a centrifugal separator.
  • a separator can be formed by a surface filter or a lamella separator.
  • the cyclone separator can preferably also be referred to as a cyclone, cyclone filter or vortex.
  • an embodiment of the cyclone separator in the form of an axial separator is preferred within the meaning of the invention, whereby an effective and space-saving separation of dirt particles from the separating device is achieved.
  • electrostatic precipitators or air washing devices that work with liquid is also conceivable.
  • a vacuum cleaner device with a plurality of separation stages for separating dirt particles is provided.
  • the disposal bag with the partition is preferably pressed against the bottom of the basic collecting container and is fixed there to the bottom by an underside of the partition.
  • the dividing wall which comprises an elastic seal, forms an effective barrier with which an exchange of gas and material between the areas which are formed within the basic collecting container is prevented.
  • the provision of this barrier and the seal effectively prevent dust from escaping from the first area of the basic collecting container into a second area of the basic collecting container.
  • This first area is assigned to a first separator, for example, and is therefore preferably set up to receive the dirt filtered out by the first separator.
  • the second area of the basic collecting container is assigned to the second separator and is preferably set up to receive the dirt separated by this second separator.
  • the partition is integrated on the suction head of the vacuum cleaning device, so that it can be removed from the basic collecting container by lifting the suction head, since the partition by lifting the suction head with it upwards and thus is moved out of the collecting container.
  • This makes the disposal bag accessible and can in particular be removed from the basic collection container in a simple and uncomplicated manner.
  • an additional insert can be used to remove the partition.
  • the suction head is preferably brought into an open position of the vacuum cleaning device by lifting, the replacement of the disposal bag taking place in particular in this open position of the suction head.
  • the vacuum cleaner can be moved into a closed position by lowering the suction head, the operation of the vacuum cleaner in particular taking place in this closed position.
  • the vacuum cleaner is preferably operated, in particular with the disposal bag inserted, so that the dirt and dust filtered out of the air flow can be collected and stored in the disposal bag in the basic collection container of the vacuum cleaner. It can also be preferred in the context of the invention that the collecting container is essentially completely emptied when the vacuum cleaner is operated without a disposal bag.
  • Additional support elements can be provided on the suction head with which the suction head, when it is removed from the vacuum cleaning device, can be placed on a floor or a sub-surface.
  • the support elements can be made longer than the partition with the seal in order not to damage or contaminate the partition and / or the seal. If the support elements are longer than the partition and / or the seal, a bottom surface of the base collection container can have recesses for receiving the support elements, so that the partition with the seal can sit flush with the base surface of the base collection container in order to create a dust-free seal the areas created with the partition wall in the basic collection container.
  • the support elements can be designed, for example, as feet or walls and are connected to the suction head.
  • the invention relates to a separator module for a vacuum cleaner.
  • a separating device is preferably disclosed which can be connected to a vacuum cleaning device.
  • the separation device is set up in particular for separating dirt particles from an air flow sucked in by the vacuum cleaner and preferably contains at least one separator.
  • the proposed separation module is characterized in that it represents an independent device that can be integrated into a vacuum cleaner as an optional additional component. In the context of the invention, it is very particularly preferred that the separation module is arranged between the collecting container and the suction head of a vacuum cleaner device or can be integrated between these components.
  • the proposed separation module is thus differentiated from conventional vacuum cleaning devices known from the prior art, since particle separators have so far usually been known as so-called stand-alone solutions, which can be used as external units in connection with a vacuum cleaning device, but which are not be integrated into the vacuum cleaner.
  • stand-alone solutions can be attached to the side surfaces or on the top of the vacuum cleaner device if required.
  • individual separation components can be integrated into the vacuum cleaner without having to be removed again.
  • the separation device is not designed as a module that can be flexibly, simply, and needs-optimized in and out of the vacuum cleaner. Such known designs are often cost-intensive and prevent a space-saving design of the vacuum cleaner device.
  • the proposed separation module for a vacuum cleaning device can preferably be designed to be particularly compact, so that it can be installed between a collecting container and the suction head without great effort.
  • the proposed separation module forms an independent functional unit that can optionally be inserted between the collecting container and the suction head.
  • this aspect of the invention enables the suction volume in the vacuum cleaning device, in particular the filter flow rate, to be kept essentially constant.
  • the proposed separation module includes intermediate collection storage for receiving separated dirt particles, in which the dust can be temporarily stored before it is fed to the collecting container of the vacuum cleaner.
  • the dust can be temporarily stored in the intermediate storage reservoirs during operation of the vacuum cleaning device, for example in particular in a time interval between two preferably automatically running filter cleaning cycles.
  • the intermediate collecting reservoirs are emptied when the vacuum is reduced in the vacuum cleaner due to the filter cleaning.
  • the dust and dirt initially stored in the intermediate storage tanks is preferably transferred to the collecting container. Because the intermediate storage reservoirs filled with the dirt particles separated by the separator are regularly emptied and their contents are discharged into the corresponding collecting container, the separating device is continuously emptied. Clogging of the proposed separator module by dirt particles is thus prevented and the period of use or service life of the separator and the vacuum cleaner is significantly increased.
  • a bottom element of the intermediate storage tank can be designed in the form of a non-return flap so that the dirt particles collected in the intermediate storage tank can fall out of the collecting tank by opening the bottom element designed as a non-return valve.
  • the bottom element can also be referred to as an opening element.
  • the separating device can be positioned in relation to a collecting container of a vacuum cleaning device in such a way that the bottom element of the intermediate collecting tank, designed as a non-return flap, can be opened in the direction of the basic collecting container. In this way, the dirt particles collected in the collecting reservoir can be conveyed into the collecting container of the vacuum cleaning device with the aid of gravity.
  • the separating device contains a frame housing which can be positioned between a suction head and a collecting container of the vacuum cleaning device.
  • the separating device can be retrofitted in a modular manner in an existing vacuum cleaning device with a suction head and a collecting container.
  • FIG 1 shows a preferred embodiment of a proposed vacuum cleaning device (1) with a separation device (2).
  • the separator (2) comprises a first separator (3) and a second separator (4), which are preferably arranged next to one another in the suction head (10) of the vacuum cleaner (1).
  • the two separators (3, 4) are preferably connected in series, so that an air flow (LS), which is generated by the vacuum cleaning device (1) with a negative pressure, first through the first separator (3) and then through the second separator ( 4) flows.
  • the inlet for the air flow (LS) in the first separator (3) is in the Figure 1 represented by the two parallel, short lines (see left in the picture).
