Embodiment Construction

[0038] figure 1 A first embodiment of an attachment 1 for a vacuum cleaner for cleaning floors is shown. The accessory 1 has a housing 2 in which a first suction opening 4 , a suction chamber 6 and a suction channel 8 are formed. The suction chamber 6 is fluidically connected to the environment of the attachment 1 via the first suction opening 4 . The suction duct 8 opens into the suction chamber 6 and is thus also fluidically connected via the suction chamber 6 to the environment of the accessory 1 .

[0039] Mounted inside the suction chamber 6 is a brush roller 10 , which is rotatable about an axis of rotation, ie can be driven in rotation by an electric motor 38 during operation of the attachment 1 . Here, the axis of rotation extends along a horizontal direction parallel to the ground.

[0040] The brush roller 10 here has a roller body 13 and a plurality of bristles 14 , for example in the form of stiff bristles, which are arranged on the roller body 13 and extend rad...

Abstract

The invention relates to an attachment of a vacuum cleaner for cleaning a floor, comprising a housing (2) with a suction mouth (4) formed in the housing (2), with a suction chamber (6) formed in the housing (2), with a rotatable brush roller (10) and with a transmission mechanism box (12), wherein the suction chamber (6) and the suction mouth (4) are fluidly connected, wherein the brush roller (10) has a roller body (13) and filaments (14) and wherein the brush roller (10) is arranged on the transmission mechanism box (12). The technical problem of providing an attachment with which both hardfloors and carpets can be cleaned in a reliable and comfortable manner is solved in such a way that the transmission mechanism box (12) is supported in the housing (2) rotatably about a substantiallyhorizontal axis (X), that a measuring device (16) is provided which obtains the sinking depth of the housing (2) into a floor to be cleaned, in particular into a carpet to be cleaned, and that an adjustment device (18) is provided which swings the transmission mechanism box (12) according to the measuring device (16).

Description

technical field [0001] The invention relates to an accessory for a vacuum cleaner for cleaning floors. The accessory has a suction port formed in a housing, has a suction chamber formed in the housing, has a rotatable brush roller, and has a transmission box. In this case, the suction chamber is fluidically connected to the suction opening, wherein the brush roller has a roller body and brush filaments, and wherein the brush roller is arranged on a gear box. Background technique [0002] The attachment in the form of a suction nozzle, referred to as a hard-floor nozzle or a brush head depending on the purpose of use, is usually connected airtight to the floor vacuum cleaner via a flexible suction and / or operating tube. In so-called hand-held vacuum cleaners, the accessories can also be connected directly to the main body of the vacuum cleaner in a gas-tight manner. The attachment here has a rotating brush roller with a roller body and a plurality of bristles, in particular ...
