Definitions

  • the invention relates to a device for vacuuming with a vacuum cleaner and a filter bag.
  • EN 60312 EN 60312 always refers to the draft standard E DIN EN 60312-1: 2009-12.
  • the air data referred to in the present description are determined analogously to EN 60312, Chapter 5.8.
  • the measuring device as described in EN 60312, chapter 7.2.7 is used.
  • the measuring chamber B described in EN 60312, Chapter 7.2.7.2 was used.
  • the measuring chamber and the vacuum cleaners according to the prior art were respectively connected to the original hoses and the original pipes.
  • Unfilled and partially filled filter bags In the present case, measurements are carried out on unfilled filter bags and on partially filled filter bags .
  • a partially filled filter bag is understood to mean a filter bag that has been filled with 400 g of DMT8 test dust in accordance with EN 60312 (Chapter 5.9.1). Notwithstanding the standard, the aspiration of the test dust is not stopped as soon as one of the three conditions specified in Chapter 5.9.1.3 is reached for the first time. Rather, always 400 g of test dust are sucked in 50 g portions.
  • suction P suction un for an unfilled filter bag and P suction part for a partially filled filter bag the values of the suction power in accordance with EN be understood to mean in 60312, with the above measuring device structure, ie measuring chamber B with orifice 8, for an unfilled or a partially filled filter bag can be determined.
  • the negative pressure in the measuring chamber for the unfilled filter bag (h un ) and for the partially filled filter bag (h part ) is measured.
  • the instruments used to measure the vacuum must meet the requirements of EN 60312, Chapter 7.2.7.3. From this measured negative pressure, the air flow q un for the unfilled and q partly for the partially filled filter bag according to EN 60312, chapter 7.2.7.2 is determined.
  • the suction power P suction un and P suction part then results analogous to EN 60312 as a product of the measured negative pressure and the air flow determined (see also EN 60312, chapter 5.8.3).
  • the negative pressure is measured in [kPa] and the air flow in [l / s].
  • the suction power results accordingly in [W].
  • Air flow As already mentioned above, the air flow according to EN 60312 with the measuring chamber according to design B is determined using aperture 8. In the prior art, this air flow is often referred to as volume flow or suction air flow.
  • Electrical power consumption of the motor / blower unit of a vacuum cleaner The electrical power P el un and P el part with unfilled or partially filled filter bag are measured with the measuring equipment specified for measuring electrical power consumption according to EN 60335, chapter 7.2.7.3. The electrical power consumption is also measured in [W].
  • electrical power consumption of other components of the vacuum cleaner device for example, a power consumption by an electrically operated brush, in the calculation of electrical power consumption out of consideration.
  • Mean power consumption of the motor / blower unit of a vacuum cleaner is an arithmetic mean of the electrical power of the motor / blower unit with unfilled and partially filled filter bag measured at aperture 8.
  • the degree of separation is measured with the Model 8130 TSI Filter Tester at 86 l / min. To generate the NaCl particles, the integrated Salt Aerosol Generator 8118A is used, which generates particles with an average particle size of 0.26 ⁇ m (so-called Mean Mass Diameter).
  • the quality factor Q S un thus results as a quotient of the suction power and the absorbed electrical power. This factor is still multiplied by the filtration efficiency of the filter material to ensure that a high suction power is not achieved by a poor separation efficiency, ie a low dust particle retention.
  • the quality factor Q S un thus represents a measure of the implementation of the electrical power absorbed by the motor / blower unit in the suction power of the vacuum cleaner with an unfilled filter bag, taking into account the degree of separation of the material of the filter bag.
  • This quality factor Q S part thus represents a measure of the conversion of the electrical power absorbed by the motor / blower unit into the suction power of the vacuum cleaner device in the case of a partially filled filter bag, taking into account the separation efficiency of the material of the filter bag.
  • filter bags Under a flat bag in the sense of the present invention filter bags are understood, the filter bag wall of two individual layers of filter material with the same surface is formed such that the two individual layers are interconnected only at their peripheral edges (the term same area does not exclude of course that the two individual layers differ from one another in that one of the layers has an inlet opening).
  • connection of the individual layers can be realized by a weld or adhesive seam along the entire circumference of the two individual layers; but it can also be formed by a single layer of filter material is folded around one of its symmetry axes and the remaining open peripheral edges of the resulting two partial layers are welded or glued (so-called tubular bag). With such a production three welding or gluing seams are therefore necessary. Two of these seams then form the filter bag edge, the third seam can also form a filter bag edge or lie on the filter bag surface.
  • Flat bags in the sense of the present invention may also have so-called gussets. These gussets can be completely unfoldable.
  • a flat bag with such gussets is for example in the DE 20 2005 000 917 U1 shown (see there Fig. 1 with folded gussets and Fig. 3 with unfolded gussets).
  • you can the gussets are welded to parts of the peripheral edge.
  • Such a flat bag is in the DE 10 2008 006 769 A1 shown (see there in particular Fig. 1 ).
  • Filter bags with surface folds A filter bag whose filter bag wall has surface folds is known per se from the prior art, for example from the European patent application 10163463.2 (see there in particular Fig. 10a and Fig. 10b and Fig. 11a and Fig. 11b). If the filter bag wall comprises several surface folds, then this material is also referred to as a pleated filter material. Such pleated filter bag walls are in the European patent application 10002964.4 shown.
  • Fig. 1 and Fig. 2 show a filter bag in cross-section with a wall, each having two surface folds. By such surface wrinkles, the filter surface of the filter bag is increased, resulting in a higher dust holding capacity of the filter bag with higher separation efficiency and longer life results (each opposite a filter bag with the same outer dimensions and no surface wrinkles).
  • Fig. 1 is a filter bag 1 with a filter bag wall 10, which has two surface folds 11 in the form of so-called dovetails shown.
  • the filter bag is shown here in cross section through the filter bag center.
  • the longitudinal axes of the surface wrinkles thus run in a plane which in turn is perpendicular to the plane of the drawing, and the surface wrinkles go at their longitudinal ends in the plane parallel to the drawing plane and lying before and behind the plane of the weld seams of the filter bag.
  • the surface wrinkles can develop most in their midst.
  • the filter bag is shown here in a state in which the surface wrinkles are already unfolded somewhat.
  • Fig. 2 is a filter bag 2 with a filter bag wall 20, which has two surface folds 21 in the form of so-called triangular folds shown.
  • the filter bag is shown here in cross section through the filter bag center.
  • the longitudinal axes of the surface wrinkles thus run in a plane which in turn is perpendicular to the plane of the drawing, and the surface wrinkles go at their longitudinal ends in the plane parallel to the drawing plane and lying before and behind the plane of the weld seams of the filter bag.
  • the filter bag is also shown here in a state in which the surface wrinkles are already unfolded.
  • Fig. 1 and Fig. 2 surface wrinkles are also possible surface wrinkles with other shapes. That the surface folds in the versions after Fig. 1 and Fig. 2 perpendicular to a bag edge is not to be understood as a limitation. Of course, the surface wrinkles may also be at an angle to the edges of the bag.
  • Pleat fixation The surface folds are expediently fixed inside the bag by strips of non-woven material.
  • FIGS. 3a and 3b It is shown how a fold fixation for dovetail folds can be made.
  • Fig. 3a Here, the top view of a filter material web 31, which includes the dovetail folds, and one in this Fig. 3a overlying nonwoven material web 32 from which ultimately the nonwoven strips used for folding fixation are formed. From the nonwoven material web 32 (which may for example consist of a spunbonded fabric with 17 g / m 2 ) rectangular holes 33 of 10 x 300 mm were punched out.
  • Fig. 3b shows the section along the line AA in Fig.
  • Diffusers in Vacuum Cleaner Filter Bags Diffusers in vacuum cleaner filter bags are known in the art. The variants used here are in the EP 2 263 507 A1 described.
  • Filter material CS50 Laminate with downstream structure: spunbond 17 g / m 2 , netting 8 g / m 2 / meltblown 40 g / m 2 / spunbond 17 g / m 2 / PP staple fibers 50 to 60 g / m 2 / carded staple fiber nonwoven 22 g / m 2 .

  • Material LT75 Laminate with the following structure: Spunbond 17 g / m 2 / Staple fiber layer 75 g / m 2 / Spunbond 17 g / m 2 .
  • the layers are ultrasonically laminated using the Ungricht U4026 lamination pattern. This filter material can be obtained from the right holder.
  • the customer requirements for the hygiene of a device for vacuuming refer not only to the lowest possible dust emissions of the devices but also to the hygienic disposal of sucked dust.

  • filter bags made of nonwoven fabrics slowly began to assert themselves.
  • filter bags were used with fleece layers of low dust storage capacity (SMS filter bag).
  • SMS filter bag low dust storage capacity

  • the European patent application 10009351.7 shows how an optimized positioning of the bag in the vacuum cleaner improves the suction capacity. For example, such filter bags show an airflow drop of only about 5% when testing the reduction of the maximum air flow with partially filled dust container in analogy to EN 60312.
  • a dust filter bag is shown with at least one inflow layer, wherein the at least one inflow layer has a NaCl separation efficiency in the sum of ⁇ 50%.
  • retaining plates have been developed with which the filter bag is sealed manually, semi-automatically or automatically before being removed from the vacuum cleaner (eg. EP 2 012 640 ).
  • Bagless vacuum cleaners - in particular cyclone vacuum cleaners - are distinguished by the fact that the air flow remains substantially constant when the dust collecting container is loaded with dust.
  • the constant air flow of a cyclone vacuum cleaner is at first glance an advantage compared to vacuum cleaners with filter bags, which clog more or less with increasing loading of the filter bag, whereby the air flow is reduced accordingly.
  • this is due to a poor efficiency, which in consequence leads to cyclone vacuum cleaners having to have a high electrical input power in order to generate a sufficient air flow.
  • This high energy input is required because of the high losses that the separation principle entails, namely the loss of maintaining the high velocity of rotation of the dust-laden air in the cyclone separator.
