Definitions
- the invention relates to a filter for a vacuum cleaner, in particular a vacuum cleaner, water vacuum cleaner or the like, a vacuum cleaner and a method for cleaning, the filter comprising a filter housing within which a suction air channel is formed for the passage of a suction air flow, the filter housing being a centrifugal separator for Separating particles from the suction air flow and having a container for receiving the separated particles.
- Such filters are well known and are regularly used for vacuum cleaners.
- vacuum cleaners serve as mobile devices for cleaning surfaces, especially floor coverings.
- a turbine for generating a suction air flow and a filter are arranged within a housing of the vacuum cleaner.
- a distinction is made in particular between vacuum cleaners with filter bags, bagless vacuum cleaners and vacuum cleaners with liquid filters or water filters and vacuum cleaners.
- a suction air flow is passed through a liquid container, whereby dust particles are wetted and bound with liquid or water.
- the disadvantage here is that the teat is only then can be used if the liquid filter is sufficiently filled with liquid.
- Bagless filters are also known which regularly have one or more centrifugal separators. With a centrifugal separator, a rotating vortex is generated in the suction air flow, with particles such as dust, fibers, smaller objects, house dust, etc., being passed due to their mass to a wall of the centrifugal separator and falling down into a collecting container or the like.
- the disadvantage here is that dust can still be contained in the cleaned suction air stream, in particular since particles in the collecting container can also be swirled up. In addition, unwanted odors can also be released back into the environment after passage through this filter. When the collecting container is emptied, fine dust can easily be released, for example when the collecting container is knocked out. Fine dust can also remain in the collecting container and get back into the suction air flow.
- the filter according to the invention for a vacuum cleaner in particular a vacuum cleaner, water vacuum cleaner or the like, comprises a filter housing within which a suction air channel is formed for the passage of a suction air flow is, wherein the filter housing has a centrifugal separator for separating particles from the suction air flow and a container for receiving the separated particles, the filter having a Dosiervor direction, which is arranged in a flow direction of the suction air flow in front of the centrifugal separator, by means of the Dosiervor direction liquid can be sprayed into the suction air stream.
- the filter is consequently essentially formed from the centrifugal separator and the container for receiving the separated particles.
- This makes it possible to use the filter as a bagless filter, namely solely through the use of the centrifugal separator, in which the separated particles fall into the container.
- the particles can be household pollution, such as dust, fibers, small objects, house dust, etc.
- the filter has a metering device, it is also possible to use the filter as a liquid filter.
- liquid for example water
- the metering device Since the metering device is arranged upstream of the centrifugal separator in a flow direction of the suction air stream, the liquid sucked in or conveyed or the water from the container or the liquid reservoir is atomized in the suction air stream and conveyed into the centrifugal separator. Since the suction air duct runs through the metering device, the suction air flow can be used as a driving medium for the metering device, with which the water is sucked in. On the way to the centrifugal separator and also within the centrifugal separator, the atomized water is mixed with the suction air, with particles or dust particles in the suction air being wetted with water and thus bound.
- suction air duct opens into the centrifugal force separator also results in an increase in pressure in the suction air flow, so that, as with a diffuser, effective wetting occurs of particles with liquid can occur.
- By continuously wetting the inner walls of the filter they are always moistened and can thus be cleaned continuously.
- the liquid and the comparatively heavier particles can be particularly easily removed from the suction air flow in the centrifugal separator and collected in the container.
- a proportion of dust that is passed out of the filter can be significantly reduced and undesirable odors can be effectively bound.
- any fine dust that may be present is also already bound in the liquid and can therefore not lead to health problems. There is no need for additional cleaning of fine dust residues.
- the metering device and the centrifugal separator can form the suction air duct, and the container can adjoin the centrifugal separator. Accordingly, the suction air duct can run solely through the Dosiervor direction and the centrifugal separator and not through the container. In contrast to liquid filters known from the prior art, the suction air flow is then not passed through the container with the liquid, whereby a suction effect can be significantly improved.
- the container can then optionally be used as a collecting container for particles or dirt for dry operation of the filter without liquid and for wet operation of the filter with liquid.
- the centrifugal separator can be formed by a cyclone, in particular a single cyclone, with a dip tube, in particular a concentric dip tube. Coming from the dosing device, the suction air flow can then enter the cyclone, the cyclone then also being able to form a diffuser when liquid is added to the suction air flow via the dosing device. With a suction device Particles in the suction air flow can reach a wall of the cyclone and fall down. The suction air cleaned in this way comes out of the cyclone via the immersion tube or emerges from it.
- the centrifugal separator can also be designed from a plurality of cyclones or as a multicyclone.
- Liquid can be conveyed from the container or from a liquid reservoir of the suction device by means of the dosing device.
- the liq stechniksreservoir can be designed as a further, separate container, which can be the object of the filter or the nipple.
- the liquid can be conveyed by suction through the Dosiervorrich device or a separate pump. A quantity of liquid can then be dosed independently of the suction power of the teat.
- the metering device can be designed by at least one jet pump, which can be connected to the container or the liquid reservoir via at least one liquid line.
- the jet pump can be formed by a Venturi nozzle as an annular nozzle or also by a plurality of Venturi nozzles, which can be connected to the container or the liquid reservoir via at least one liquid line. Liquid or water can be sucked in from the container or the liquid reservoir via the liquid line and fed permanently to the jet pump.
- the jet pump can already be designed through an opening in a duct wall of the suction air duct.
- the dosing device can be coupled as a separate assembly to the centrifugal separator and the container, for example in such a way that the dosing device can be easily dismantled and cleaned by them.
- a shut-off valve can be arranged on the liquid line. With the shut-off valve, the liquid line can be completely closed, partially opened or completely opened, so that the introduction of liquid into the suction air flow via the metering device can also be prevented or adjusted as required. If the liquid line is closed with the shut-off valve, the filter can be used in dry mode. Then, even if there is liquid in the container, it is not introduced into the centrifugal separator. At the same time it is possible to suck up liquid with a suction device having the filter and to separate it in the filter.
- the shut-off valve can be formed particularly simply by a flexible hose section of the liquid line, which clamps mechanically ge and can be closed.
- a liquid filter can be arranged on a bottom of the container, wherein the liquid filter can be formed by a dam which is formed on the bottom and which can be closed with a sieve opposite an interior of the container, wherein the liquid line can be connected to the liquid filter and can flow inside the dam.
- the dam can, for example, be arranged centrally on the floor, that is to say centrally.
- the dam can be formed by a circumferential, circular web on the ground.
- the sieve can be arranged on the dam or attached to it and so separate the interior of the loading container from an interior of the dam.
- a bottom wall with at least one opening for the passage of separated particles from the centrifugal separator into the container can be formed.
- the bottom wall can then separate the centrifugal separator from the container, wherein the bottom wall can be attached to the centrifugal separator or the container.
- the opening formed in the bottom wall or a plurality of openings can serve to pass through particles which have been separated from the suction air flow by the centrifugal separator and which sink downwards. The particles that get through the opening can now fall into the container and be collected in it.
- the size of the opening is advantageously dimensioned such that there is no renewed turbulence of particles in the container as a result of the suction air flow guided past the opening.
- the opening can be continuously annular. No fibers can then adhere to the opening. If the filter is running wet, the liquid can also enter the container through the opening.
- the bottom wall can form a substantially flat bottom of the centrifugal force separator, wherein a circular web can be formed in sections on the bottom, which can be interrupted in a region of the opening.
- Particles can thus collect between the annular web and the outer wall of the centrifugal separator, without these in a center of the centrifugal separator and thus below of the immersion tube. This increases functional reliability when the filter is used for a long time. Nevertheless, due to the vortex generated in the centrifugal separator, these particles can be guided in the suction air stream along the web up to the opening.
- the web can be interrupted in the area of the opening, so that here too particles located below the immersion tube can get into the opening.
- the cleaning effect of the filter in dry operation and in wet operation can be significantly improved by the formation of the web.
- the opening can be arranged ⁇ 90 ° on a radial outer edge of the bottom wall relative to an inlet opening of the suction air flow in the centrifugal force separator. Since the particles or liquid collect on the radial wall of the centrifugal force separator, they can then easily get into the opening if it is formed on the outer edge of the bottom wall. As has surprisingly been shown, a particularly good cleaning effect of the suction air can be achieved if the opening is at an angle of ⁇ 90 °, for example at an angle of> 70 ° relative to the inlet opening in the bottom wall. The angle is defined here as an angle relative to an axis of rotation of the centrifugal separator.
- the bottom wall can form an edge at the opening, wherein the edge can be configured in sections, based on a cross-section of the bottom wall, with a rounding, preferably with a rounded projection extending in the container. If the particles, fibers, hair or even smaller objects separated by the filter are, they can get stuck in the opening or on the edge of the suction air flow swirled in the centrifugal separator and cannot easily get through the opening into the container. This can be remedied in particular in that the edge is formed with a rounding.
- the rounding can be dimensioned so large that it is larger than an undercut of the bottom wall. this can be achieved in that a projection is formed on the bottom wall which extends into the container.
- the projection can be designed in the manner of a nose or a rounded web. Because of the comparatively large rounding, the adhesion of fibers or the like to the edge of the opening can be effectively avoided.
- the bottom wall can be connected to a hinge which allows the container to be opened and closed by pivoting the base wall relative to the container.
- the container and the bottom wall can also optionally be connected to a hinge which allows the container to be opened and closed by pivoting the bottom wall or the centrifugal separator relative to the container. This makes it possible to empty the container without it having to be completely separated from the centrifugal separator. If, for example, a handle is arranged or formed on the container, the hinge can be arranged in the region of the handle so that the container and bottom wall can be pivoted easily by actuating a lever with a finger. The Benzol ter can then be opened and closed with one hand, which makes handling of the filter much easier.
- a seal for example a rubber seal, can be arranged between the container and the bottom wall or the centrifugal separator, which seals it tightly and thus prevents particles or liquid from escaping.
- a seal can result in particular from the formation of a suction air flow, since a negative pressure is then formed in the centrifugal separator and the container.
- a special closure between the container and the bottom wall or centrifugal separator is then no longer necessary.
- a handle for handling the container can be arranged on the container. The handle can for example be molded onto the container and designed in the manner of a handle. The handle makes it possible to handle and clean the container particularly easily.
- the handle can be designed so that it can be easily gripped with one hand.
- a liquid line of the metering device is guided through the handle.
- a shut-off valve can be integrated in the handle, which can then be easily operated with the hand holding the handle.
- a separating plate for separating fine dust can be arranged, which can subdivide an interior of the Benzol age into an upper receiving space and a lower receiving space, wherein the separating plate can rest with an outer contour on an inner wall or inner side of the container and a gap can be formed in sections between the contour and the inner wall.
- the separating plate can be designed to be essentially flat, so that the separating plate is easy to clean.
- Dust that collects in the container can enter the lower receiving space through the gap between the inner wall and the contour of the separating plate, with larger particles such as fibers or smaller objects remaining in the upper receiving space.
- the separator plate prevents unwanted swirling of fine dust by the suction air flow trained in the centrifugal separator, which can also lead to air movements in the container. Emptying the container is also made easier, since the fine dust is not necessarily whirled up when it is emptied.
- the separation plate can be combined with the sem.
- the separation plate can be arranged on a sieve of the liquid filter or formed together with it. It is also advantageous if the bottom of the container is smooth and uninterrupted so that the container can be cleaned easily.
- the container can be circular, which is particularly advantageous when there is liquid in the container.
- liquid can slosh in the container or a wave can form through which liquid can get back into the centrifugal separator.
- the circular design of the container this can be effectively prevented, since a wave cannot hit a straight surface head-on.
- smaller particles can advantageously collect in the lower receiving space.
- the liquid filter can therefore be arranged in the upper receiving space so that the smaller particles cannot be sucked into a liquid line.
- the gap can be arranged on a side of the separating plate facing away from or facing a handle. If a handle is formed on the container, it is advantageous if the gap is formed on the side of the separating plate facing the handle, so that when the container is emptied, if it is tilted with one hand starting from the handle, fine dust in the lower Receiving space remains and does not get through the gap in the upper receiving space. Conversely, when the gap is arranged facing away, fine dust can be conveniently disposed of when the container is emptied.
- the gap can be arranged at an angle of 90 ° or 270 ° relative to the handle.
- the separating plate can then be attached to the bottom of the container, for example by means of a plug connection, in such a way that the desired alignment of the gap always results. When cleaning the container, the separating plate can then also easily be removed from the container.
- the filter can have a fill level sensor by means of which a fill level of a liquid bath in the container can be detected. It is already sufficient if a maximum fill level can be detected with the fill level sensor. This ensures that the container will not be overfilled when liquid is sucked up comes with liquid. When the maximum filling level is reached, the vacuum cleaner can be switched off.
- the level sensor can be formed by a floating body in the container and a reed contact outside the container.
- the floating body can be designed with a magnet which actuates the reed contact outside the container.
- the reed contact can be arranged in the suction cup adjacent to the floating body.
- the filter then does not have any electrical lines that could come into contact with liquids. A safety of the filter can be significantly improved in this way.
- An intermediate filter and / or a particulate filter can or can be arranged in the suction air duct, wherein the intermediate filter and / or the particulate filter can be arranged in the direction of flow of the suction air stream following the centrifugal separator.
- the intermediate filter can, for example, be a filter formed from a so-called foam material, which is open-lined and thus allows the suction air flow to pass through.
- the intermediate filter can be arranged downstream of the centrifugal separator in a flow direction of the suction air flow. With the intermediate filter, liquid particles or fine dirt particles can be separated and collected particularly easily from the suction air flow. Such an intermediate filter can also be cleaned easily, for example by washing it out.
- the suspended matter filter can be arranged downstream of the intermediate filter or the centrifugal separator in the flow direction of the suction air duct.
- the suspended matter filter can be used to remove any finer dust particles that may still be in the suction air.
- the particulate filter can be a HEPA filter.
- the HEPA filter high-efficiency particulate air filter
- the HEPA filter can be formed, for example, by a fleece or a plurality of layers of a fleece.
- Inner surfaces of the centrifugal separator and / or the container can be designed with a self-cleaning nanostructured surface.
- the nanostructured surface can be formed by a layer, for example by a lacquer. A so-called lotus effect can be achieved with a nanostructured surface, in which the adhesion of particles or liquid to the surface is essentially prevented. Cleaning the filter is made much easier in this way.
- the vacuum cleaner according to the invention in particular vacuum cleaner, water vacuum cleaner or the like, comprises a housing, with a suction air duct being formed within the housing, which connects a suction air inlet, in particular for connecting a suction hose to the housing, and a suction air outlet, the suction device being a turbine for Formation of a suction air flow in the suction air duct and a filter according to the invention comprises.
- the suction device can furthermore comprise a suction hose, a suction nozzle arranged on the suction hose and a reel arranged inside the housing with a cable for supplying power to the suction device.
- the cleaning method is carried out with a vacuum cleaner, in particular Staubsau ger, water vacuum cleaner or the like, with a filter, with a suction air flow through an im Filter housing formed suction air channel is passed, wherein in a centrifugal separator of the filter housing from the suction air flow particles are separated and taken up in a container of the filter housing, by means of a metering device of the filter, which is arranged in a flow direction of the suction air flow in front of the centrifugal separator, liquid in the Suction air flow is sprayed.
