Embodiment Construction

[0031] figure 1 A three-dimensional illustration of the cleaning unit 1 in suction operation is shown. The cleaning unit 1 has a filter 2 , a filter element 3 , a filter basket 4 , a filter holder 5 and a spring element 6 which is arranged between the filter basket 4 and a rotary unit 7 . The rotary unit 7 is accommodated in the filter head 9 at the first bearing seat 8 and in the filter holder 5 at the second bearing seat 10 .

[0032] The second bearing seat 10 is formed by an annular protruding section 11 designed in one piece with the filter holder 5 . Furthermore, the filter holder 5 has a receiving opening 12 into which the filter 2 engages in a form-fitting, frictional and / or material-fitting manner.

[0033] In the region of the filter head 9 the rotary unit 7 is accommodated in the first bearing seat 8 in a form-fitting manner, eg as shown. A spring element 6 is arranged between the first bearing seat 8 and the rotary unit 7 , wherein the spring element 6 is design...

Abstract

The invention relates to a cleaning unit (1) for a cleaner, comprising a filter (2), a rotary unit (7) rotatably received inside the filter (2), a first bearing seat (8) provided inside the filter (2) and used for the rotary unit (7), and a second bearing seat (10) used for the rotary unit (7), wherein the rotary unit (7) is fixed in the filter (2) by means of the second bearing seat (10). The provided cleaning unit (1) enables a nozzle adopted for cleaning to be well supported and in particular, prevents the rotation of the nozzle adopted for cleaning from rotating in the cleaner.

Description

technical field [0001] The invention relates to a cleaning unit for a vacuum cleaner having a filter, a rotary unit rotatably accommodated in the filter, and a first bearing seat for the rotary unit arranged in the filter . Background technique [0002] Known vacuum cleaners collect dust and / or dirt by means of a suction airflow produced by means of a blower, from which the airflow is separated and collected in the vacuum cleaner before the airflow is cleaned and discharged back into the surrounding environment. Contains particles. Different principles of particle separation are used for the separation, such as filter bags, permanent filters or cyclones. While the filter bag is suitable for the separated dust and / or dirt to collect in the filter bag for manual cleaning together, the permanent filter stays in the equipment for a longer period of time, and the separated particles are collected in a separate The filter is emptied inside the container. [0003] In order to m...
