Embodiment Construction

[0040] figure 1 A sectional view of the brushroll 1 and the first exemplary embodiment of the cleaning device 2 is shown in a first operating state. The brushroll 1 may be part of a conventional rotary brushroll vacuum cleaner, with which a cleaning nozzle is fitted.

[0041] The brushroll 1 comprises a cylindrical or tubular body 3 . From the main body 3 project radially brushes or bristle tufts 4 intended for raising and collecting dust. especially in image 3 As can be seen in , these bristle bundles 4 can be arranged in one or more helical lines along the outer surface of the main body 3 .

[0042] The cleaning device 2 includes a cleaning element 5 . The cleaning element 5 is configured to be rotatable about an axis 6 extending substantially parallel to the longitudinal axis of the body 3 . Possible rotational movements of the cleaning elements 5 are indicated by curved arrows. The same applies to the brush roller 1 .

[0043] The cleaning element 5 comprises a bas...

Abstract

The invention is in particular directed to a cleaning device for a rotatable cleaning member (1) of a vacuum cleaner nozzle (16), the cleaning device (2) being configured and adapted for at least one wound around said rotatable cleaning member (1) loosens debris and includes a cleaning element (5) configured for selectively engaging and disengaging the rotatable cleaning member (1) during operation of a cleaning process.

Description

technical field [0001] The invention is directed to a cleaning device for a rotatable member of a vacuum cleaner, a vacuum cleaner nozzle, a vacuum cleaner and a cleaning unit. Background technique [0002] In vacuum cleaners such as upright, stick, robot, canister vacuum cleaners with rotatable or swivel brush heads, there is the problem that elongated objects tend to get tangled or wrapped around the brush head during operation , especially thread, cotton fibres, textile fibres, hair and the like. [0003] Entangled or wrapped objects can significantly affect the operation and / or cleaning efficiency of the brush head or corresponding vacuum cleaner nozzle. [0004] A system for removing threads and the like from brush heads of vacuum cleaners is known, for example, from patent WO 2009 / 117383 A2. However, there is still room for improvement and alternatives for removing wind-up debris from the rotating brush head of a vacuum cleaner. Contents of the invention [0005] ...
