Filter device for a vacuum cleaner and filter dedusting method
A filter device for a vacuum cleaner. The filter device has two chambers, of which in each case at least one participates in suction operation of the vacuum cleaner, while a filter element of the other chamber can be dedusted. As a result, while one filter element is being dedusted, suction operation can be maintained through the other chamber of the vacuum cleaner. This advantage is allowed by an elastic membrane, which can change shape and/or move when the chamber to be dedusted is ventilated. The ventilation is effected by a pressure equalizing stream which can pass through a ventilation channel and a ventilation opening into the chamber to be dedusted. As a result of the movement and/or change in shape of the elastic membrane, a dedusting pulse is applied to the filter element, which can ensure, for example, that a solid filter cake is detached and drops into the dust collecting tank of the vacuum cleaner. A method for dedusting a filter device in a vacuum cleaner is also provided.
