Problems solved by technology

In the case of vacuum cleaners, a significant disadvantage of the known solution is that, as a result of the deposition of the odor-generating substances flowing into the odor filter together with the air flowing due to convective transport, the deposition of the odor-generating substances takes place substantially simultaneously with the operation of the vacuum cleaner.
On the one hand, the cross-flow associated with it causes an undesirably high pressure loss

Embodiment Construction

[0026] First, a vacuum cleaner 1 with a dust filter bag 3 fixed in a filter chamber 2 will be described with reference to FIG. 1 . When the vacuum cleaner 1 is in operation, the schematically indicated motor / fan unit 4 generates a negative pressure in the region of the suction nozzle 5 on the floor side, by means of this negative pressure dust and dirt particles are removed from the floor 6 to be cleaned, and suction The air flow is conveyed into the dust filter bag 3 via a suction duct (not shown). The motor / fan unit 4 is connected downstream of the dust filter bag 3 in the airflow direction.

[0027] The dust that packs into the dust filter bag 3 stays there for a certain period of time. Odor-generating substances are generated during this period due to microbial degradation of substances contained in various dusts, and these are absorbed as described in detail later.

[0028] To this end, an absorbent 7 in the form of activated carbon, zeolites or porous polymers is intro...

Abstract

The invention relates to a method for vacuum cleaning using a hand vacuum cleaner (1). The dust is first collected in a dust collection container (9), for example a dust filter bag (3), and then disposed of. An adsorbent (7), for example activated carbon, is also provided for adsorbing odours. The invention also relates to a dust filter bag (3) or dust collection compartment (9) for a vacuum cleaner (1). The aim of the invention is to improve a method and a dust filter bag (3) or a dust collection compartment (9) of this type in terms of advantageously preventing or reducing the initial odour surge. To this end, the adsorbent (7) is introduced directly into the dust collection compartment (3, 9) and an adsorbent (7) is provided in the dust filter bag (3) or the dust collection compartment (9) in a loose form.

Description

technical field [0001] The invention firstly relates to a method of vacuuming with a hand-held vacuum cleaner, in which the dust is first filled into a dust collection container, eg a dust filter bag, and then removed, and odors are also absorbed by means of an absorbent, eg activated carbon. Background technique [0002] Such methods are known in which adsorption filters are used for the absorption of odors, the main components of which are absorbents for binding the odor-generating substances and carrier materials suitable for immobilizing the absorbents. Porous materials, in many cases for example activated carbon, are used as absorbents. However, other materials such as zeolites or porous organic polymers can also be used. Absorbents mostly consist of granules, which can exist in different shapes and sizes. They are distributed on the filter in a defined manner by means of different load-bearing structures, such as foam, fabric, non-woven fabri...
