Embodiment Construction

[0029] figure 1 An extraction cleaning device 1 is shown, which is designed here as a battery-operated hand-held vacuum cleaner. The suction cleaning device 1 has a suction nozzle 13 which is guided over the surface to be cleaned during normal suction operation of the suction cleaning device 1 . In this case, the user of the suction cleaning appliance 1 holds the suction cleaning appliance 1 by means of a handle 14 formed on the housing of the suction cleaning appliance 1 . The handle 14 also has a switch 15 , which is designed here as an on and off switch, for example. As shown in the figure, the suction cleaning device 1 has a fan 2 and a dust collection chamber 3 inside. When the fan 2 is running, the air flows to the fan 2 through the suction nozzle 13 . The air flows through the dust collection chamber 3 , in which the aspirated matter contained in the air is optionally trapped by means of an air filter 4 .

Abstract

The invention relates to a suction cleaning device (1), in particular a battery-operated hand-held vacuum cleaner, having a fan (2), a dust collection chamber (3) and a vacuum cleaner arranged between the fan (2) and the dust collection chamber (3). The air filter (4) can be flowed through from the dust chamber (3) in the direction of the fan (2) in the suction mode and along the suction side in the regeneration mode Run in the opposite direction to the flow being worn. In order to provide a suction cleaning device (1) in which the regeneration of the air filter (4) and / or the dust chamber (3) is optimized, the air filter (4) is mounted movably in its entirety on the suction In a suction cleaning device (1), in particular for regenerative operation, the position is moved from the position corresponding to the suction operation in the direction of the fan (2). The invention also relates to a method for operating an extraction cleaning device (1).

Description

technical field [0001] The invention relates to a suction cleaning device, in particular a battery-operated hand-held vacuum cleaner, with a fan, a dust collection chamber and an air filter arranged between the dust collection chamber and the fan, which air filter is removed during suction operation The flow flows through the dust chamber in the direction of the fan, and in regeneration mode in the opposite direction to the suction mode. Background technique [0002] Suction cleaning devices of the above-mentioned type are known in the prior art. The suction cleaning device has an air filter for cleaning the air flowing into the fan of the suction cleaning device from dust and / or dirt. In particular in battery-operated suction cleaning appliances, regenerable air filters, so-called permanent filters, are often used which remain in the suction cleaning appliance and are emptied, for example, at the base station for the suction cleaning appliance. . Suction operation with a...
