Benefits of technology
The invention provides a vacuum-cleaning apparatus that maintains a constant airflow even when the filter bag is loaded with DMT8 dust. The motor-fan unit is designed to not increase its power more than a certain percentage, such as not more than (35%) when the filter bag is loaded. The use of a motor-fan unit with a switched reluctance motor further improves the efficiency of the apparatus. The vacuum cleaner bags with pleated filter material or surface folds help reduce airflow drop and further contribute to the stable airflow. The improvement in efficiency of the apparatus results in a more energy-saving solution.
Problems solved by technology
This high input power is necessary owing to the high losses brought about by the separating principle, namely the loss for the maintenance of the high rotational speed of the dust-laden air in the cyclone separator.
However, this is opposed by a nominal electric input power of far more than 2000 W. Cyclone vacuum cleaners having an electric input power of approximately 1400 W allow the realization of an airflow of about 25 l / s.
For this reason, this concept was not pursued and, therefore, could not be implemented in a product successful on the market.

Embodiment Construction
[0040]Given the aforementioned disadvantages of the prior art the invention is based on the object to provide a vacuum-cleaning apparatus in which a constantly high airflow is realized despite a low nominal electric input power.
[0041]This object is achieved by a vacuum-cleaning apparatus comprising the features of patent claim 1, viz. by a vacuum-cleaning apparatus comprising a vacuum cleaner and a filter bag made of non-woven fabric, wherein the vacuum cleaner has a nominal electric input power of less than 1200 W, preferably less than 1100 W, more preferably less than 900 W, the vacuum cleaner comprises a motor-fan unit and a controlling device controlling the vacuum cleaner such that the airflow is kept substantially constant at a value of at least 34 l / s, preferably substantially constant at a value of at least 37 l / s, more preferably substantially constant at a value of at least 40 l / s when the filter bag is loaded with DMT8 test dust analogous to EN 60312, and the filter bag i...

The invention relates to a vacuum-ceaning apparatus comprising a vacuum cleaner and a filter bag made of non-woven fabric, wherein the vacuum cleaner has a nominal electric input power of less than 1200 W, preferably less than 1100 W, more preferably less than 900 W, wherein the vacuum cleaner comprises a motor-fan unit and a controlling device controlling the vacuum cleaner such that the airflow is kept substantially constant at a value of at least 34 l / s, preferably substantially constant at a value of at least 37 l / s, more preferably substantially constant at a value of at least 40 l / s when the filter bag is loaded with DMT8 test dust analogous to EN 60312, and wherein the filter bag is a disposable filter bag made of non-woven fabric which has an airflow drop of less than 15%, preferably less than 10%, more preferably less than 5% in tests demonstrating the reduction of the maximum airflow with a partially filled dust container analogous to EN 60312.
Description
FIELD OF THE INVENTION[0001]The invention relates to a vacuum-cleaning apparatus comprising a vacuum cleaner and a filter bag made of non-woven fabric.DEFINITIONS[0002]The description of the prior art and the invention is based on the standards, definitions and measuring methods specified below:[0003]EN 60312: EN 60312 denotes the standard in version EN 60312:1998 +A1:2000 A2:2004.[0004]EN 60335: EN 60335 denotes the standard in version EN 60335-2-22010.[0005]Determination of air data: The air data of a vacuum cleaner are determined according to EN 60312, chapter 2.8. The measuring device B according to chapter 5.2.8 is used. if motor-fan units sob are measured, viz. without a vacuum cleaner case, the measuring device B is applied equally.[0006]The measurement of the reduction of the maximum airflow with a partially filled dust container according to chapter 2.9 is carried out with orifice 8 (40 mm).[0007]Nominal electric input power of a vacuum cleaner: The input power of a vacuum ...
