Problems solved by technology

[0004] Even if the filter chamber designed to accommodate the sucked-in suction has not been completely filled and can in principle accommodate more suction, the filter element can be damaged in a disadvantageous manner during filter operation. Aspirate completely blocked
The problem here is that, although the filter chamber still has a holding capacity, the filter operation is stopped or at least blocked

Embodiment Construction

[0022] figure 1 A vacuum cleaner 1 according to the invention is shown, designed here as a household floor vacuum cleaner. The vacuum cleaner 1 has a suction nozzle 17 , a filter chamber 16 with an air filter 2 and a fan 19 . During the cleaning process of the floor surface, aspirated matter is sucked into the filter chamber 16 by means of the fan 19 through the suction nozzle 17, and the aspirated matter is filtered in the filter chamber by means of the air filter 2, so that only filtered clean air reaches the fan 19 and exhaust to the surrounding environment. The air filter 2 is hereafter designed as a backwashable air filter 2 .

[0023] figure 2 A first embodiment of a back-flushable air filter 2 is designed. A partial area of ​​a filter chamber 16 of a vacuum cleaner 1 is shown, which has a first housing subarea 20 and a second housing subarea 21 which are joined together interconnected in area 22. Arranged in the filter chamber 16 is a back-flushable air filter 2 ...

Abstract

The invention relates to an air filter (2), which is especially used for a household dust collector (1). The air filter (2) is provided with a filter element (5) which separates a clean-air space (3) from a suction space (4), and the filter element (5) is operated in a filter operation of air to be cleaned from the direction of the suction chamber (1), and the air filter (2), in particular for a household vacuum cleaner (4) in the direction of the clean-air space (3) and with an action element (6) designed to act on the filter element (5) on the clean-air side. In order to provide an air filter (2), which allows a longer filter operation over a longer period of time and whose function is not hindered by the suction material, it is proposed that, with the flow through the filter element (5), the filter element (6) is moved from the suction space (4) (3) can be activated on the filter element (5) by virtue of an air flow which can be triggered under the influence of pressure control and acts on the influencing element (6).

Description

technical field [0001] The invention relates to an air filter, in particular for household vacuum cleaners, with a filter element separating a clean air chamber from a dust collection chamber, from which the air to be cleaned is extracted during filtering operation The direction of the chamber flows through the filter element in the direction of the clean air chamber, and the air filter has an active element designed to act on the filter element on the clean air side. Background technique [0002] Air filters of the above-mentioned type are known. The air filter is usually used to clean the suction air loaded with suction. In combination with a vacuum cleaner, the air filter is used to protect the fan of the vacuum cleaner from being clogged by the suction being sucked in. Running through filtration usually results in progressive clogging of the filter material with aspirate, requiring removal of aspirate depending on the duration of the run. [0003] For example, documen...
