Embodiment Construction

[0062] Figure 5 A characteristic curve of a motor fan unit according to an embodiment of the invention is shown. The motor fan unit is characterized by a relatively low maximum negative pressure with hole 0 and a high volumetric flow with hole 9 (50 mm). Especially with hole 0 a negative pressure of 14.3 kPa was obtained. Hole 9 (50 mm) produces an air velocity of 86.5 dm / s. Therefore, the characteristic curve is very flat. At maximum air flow, the motor dissipates 1240W of power. With hole 7 (30mm), the air flow rate power (the product of negative pressure and air flow rate) reaches a maximum value of 498W.

[0063] However, Figure 4 The characteristic data of a motor fan unit used in a vacuum cleaning device according to the prior art are shown. Using hole 0, the motor fan unit generates a negative pressure of 35.8 kPa and hole 9 (50 mm) generates an air velocity of 53.5 dm / s. Therefore, the characteristic curve of the fan is very steep. At maximum air flow, the mo...

Abstract

The invention relates to a vacuuming device which comprises a vacuum cleaner and a bag filter and in which the vacuum cleaner has a rated input power of less than 1200 W, preferably less than 1100 W, especially preferably less than 900 W, the vacuum cleaner has a motor-fan unit and a regulation device that regulates the vacuum cleaner in such a way that the air flow is kept essentially constant at a minimum value of 34 l / s, preferably essentially constant at a minimum value of 37 l / s, especially preferably essentially constant at a minimum value of 40 l / s when the bag filter is loaded with DMT8 test dust according to EN 60312, and the bag filter is a disposable filter that is made of nonwoven fabric and has a drop in air flow of less than 15 percent, preferably less than 10 percent, especially preferably less than 5 percent when testing the reduction in maximum air flow with a partly filled dust receptacle according to EN 60312.

Description

technical field [0001] The invention relates to a vacuum cleaning device comprising a vacuum cleaner and a filter bag made of non-woven fabric. [0002] definition [0003] The prior art and the invention are described on the basis of the criteria, definitions and measurement methods specified below: [0004] EN60312: EN60312 means the standard version EN60312:1998+A1:2000+A2:2004. [0005] EN60335: EN60335 means the standard version EN60335-2-2:2010. [0006] Determination of air data: The air data of vacuum cleaners are determined according to EN60312, chapter 2.8. Measuring equipment B according to chapter 5.2.8 was used. If the motor fan unit is measured alone, ie without the vacuum cleaner, the measuring device B applies equally. [0007] Using hole 8 (40 mm), the reduction in maximum air velocity is measured according to chapter 2.9 with a container partially filled with dust. [0008] Nominal electrical input power of the vacuum cleaner: The input power of the vac...
