Definitions
- the invention deals with the problem of odor nuisance when vacuuming, due to the dust separated in the course of the suction process in a filter bag.
- the suction air passing through the filter bag walls after the dust has been separated off is generally contaminated with odors which are perceived as unpleasant.
- a fragrance element is provided on the exhaust air side of a filter bag, which is dust-laden with compressed air passing through the filter bag walls, the fragrance element being attached to the outside of the filter bag and the exhaust air being drawn off in a sweeping manner over the outside of the filter bag.
- the smell of dust which is perceived as unsuitable, is masked by scenting, the advantageous arrangement of the fragrance element on the outside of the filter bag first filtering the compressed air passing through the filter bag walls.
- a blower motor is arranged in the suction direction behind the filter bag and sucks the dust-laden suction air flow through the filter bag.
- the exhaust air emerging from the filter bag sweeps over the outside of the filter bag and in doing so absorbs fragrances from a perfume oil or the like.
- the fragrance element is accordingly arranged according to the invention at a point in the suction air duct which is arranged in the flow direction behind the areas which are subject to odor, such as the collecting space in the filter bag.
- the fragrance element is attached to the outside of the filter bag wall.
- the fragrance element is attached to a holding plate of the filter bag and the exhaust air is drawn off in a sweeping manner over the holding plate.
- the filter bag is through an opening in the holding plate from the Dust-laden compressed air passing through filter bag walls.
- the filter bag is preferably seated in a filter chamber receptacle which forms a capsule and surrounds the filter bag, the inner wall of the chamber being spaced apart from the filter bag walls.
- the odor-laden exhaust air emerging from the filter bag is drawn off through the space formed thereby and passed over the holding plate, in the area of which the fragrance element arranged there is contacted.
- the solution according to the invention in a combination in which adsorbent is loosely introduced into the filter bag proves to be particularly advantageous.
- DE 100 30 958 AI The content of this patent application is hereby incorporated in full into the disclosure of the present invention, also for the purpose of including features of this patent application in claims of the present invention.
- the adsorbent can be present in bulk in the dust filter bag, further preferably activated carbon powder with a grain size fraction between 0.15 and 0.25 or an adsorbent made of activated carbon fibers with a fiber diameter of 0.01 to 0.1 mm and a fiber length up to 10 to 100 mm is provided.
- the adsorbent can be contained in a separate, air-permeable covering within the filter bag, which air-permeable covering is, for example, a nonwoven fabric.
- the type and amount of the activated carbon serving as the adsorbent and the type and amount of the fragrance constituents in the fragrance element are matched to one another.
- the activated carbon adsorbs the unpleasant smell of the dust in the filter bag during the idle period, ie when the vacuum cleaner is not in use, and reduces the fragrance of the fragrance element which may initially be too strong.
- the activated carbon is coated with dust and only absorbs the smell of dust. During suction, the smell of the newly vacuumed dust, which is not adsorbed by the activated carbon, is pleasantly masked by the scent of the fragrance element.
- the fragrance element is a plastic injection-molded part with fragrance components embedded therein. It is proposed that the fragrance element preferably consists of polyethylene or ethylene vinyl acetate, with about 2 to 20% perfume oil being incorporated in the spraying process. A total weight which is between 2 and 8 g proves to be advantageous in terms of handling technology, the surface, in particular the effective surface of the fragrance element to be covered by the exhaust air, being about 10 to 100 cm 2 .
- the distribution of the fragrance components, in particular the perfume, in the fragrance element is homogeneous.
- the fragrance oil can only escape from the fragrance element by diffusion.
- the perfume oil introduced is preferably composed of low solvents and is also thermally so stable that it can be briefly heated to 150 to 250 ° C.
- the fragrance element cannot be attached to the filter bag, for example on the outside on the filter bag wall, or on the holding plate in a non-destructive manner, for example by gluing.
- Such a fragrance element contains an amount of fragrance oil which is adapted to the usual useful life of a filter bag.
- fragrance elements preferably in the form of a plastic injection-molded part, can have a predetermined useful life exceeds the usual service life of a filter bag. Such scent elements that are held in place by clips or clips are exchanged at predetermined intervals.
- FIG. 1 shows a perspective cut-out illustration of a vacuum cleaner with a filter bag which is received in a filter chamber and has a fragrance element according to the invention
- FIG. 2 shows the filter chamber with the filter bag inserted in a single perspective
- FIG. 3 shows the filter bag with the fragrance element according to the invention arranged in a single perspective, with the filter bag wall partially broken open;
- FIG. 5 shows a sectional view according to FIG. 4, but with the scent element being held in the slide on the holding plate;
- FIG. 6 shows a further sectional illustration corresponding to FIG. 4 when the fragrance element is held in clips on the holding plate.
- a basic device 1 of a vacuum cleaner with a vacuum cleaner housing 2 and a filter chamber 3 which is held there in a hinged manner for receiving a filter bag 4 is shown and described with reference to FIG. 1.
- This suction channel 6 is connected to a filling opening 8 formed on a holding plate 9 of the filter bag 4.
- the filter bag 4 is dust-loaded in the usual way by the incoming air flow (arrow a), after which the air flow, passing through the filter bag walls 10, is guided between the filter bag wall 10 and the inner chamber wall 11 with deflection in an approximately opposite direction to the entry direction (see arrow b).
- This dust-free air drawn in by the blower motor 5 is drawn off in a sweeping manner both over the filter bag walls 10 and over the holding plate 9, which is used for this exhaust air (arrow b) to pass over a fragrance element 12 arranged on the holding plate 9 and thereby in the Fragrance element entrains 12 stored fragrance components.
- the fragrance element 10 is produced as a plastic injection-molded part with fragrance components embedded therein, with polyethylene or ethylene-vinyl acetate preferably being used with regard to the plastic material.
- the proportion of fragrance in the fragrance element 12 is approximately 2 to 20%, with perfume oil preferably being introduced as the fragrance component, with a homogeneous distribution within the fragrance element 12.
- the fragrance oil or the fragrance constituents emerge exclusively by diffusion.
- adsorbent 13 in the form of activated carbon powder or activated carbon fibers is introduced into the filter bag 4, the type and amount of activated carbon and the type and amount of the fragrance components stored in the fragrance element 12 being coordinated with one another.
- the activated carbon adsorbs the unpleasant smell of the vacuum cleaner during the downtime dust deposited in the filter bag 4 and the scent of the fragrance element 12 which may initially be too strong when the filter bag is newly inserted. As the degree of filling in the filter bag 4 increases, the coal is coated with dust and only increases the smell of dust.
- the odor of the newly absorbed dust which is not adsorbed by the activated carbon, is pleasantly covered by the fragrance of the fragrance element 12, which ensures that initially there is not too much fragrance, the dust smell in the filter bag 4 is adsorbed over the period of use, and the dust smell during Suction is covered. This ensures a uniformly pleasant and discreetly scented blow-out air (arrow b) over the entire service life of the filter bag 4.
- the fragrance element 12 can be on the outside, ie. H. be glued to the surface of the holding plate 9 facing away from the filter space or, depending on the choice of material of the holding plate 9, also welded, which ensures a constant change of adsorbent 13 and fragrance element 12 in the changing cycle of the filter bag 4.
- FIG. 5 and 6 show, however, a reversible fastening of the fragrance element 12 on the holding plate 9 is also conceivable, for example, as shown in FIG. 5, by a sliding holder, for which purpose the fragrance element 12, for example, in the longitudinal extension thereof in a , is inserted by means of rails 14 attached to the holding plate 9 and the receptacle is inserted.
- a clip holder is also conceivable, for which purpose latching elements 15 provided with latching lugs are attached to the holding plate 9, which initially deflect resiliently when the plate-shaped fragrance element 12 is pressed into the receptacle formed, and finally a rear grip for holding the fragrance element 12 shapes.
