Definitions
- the invention relates to a brush attachment for household vacuum cleaner with a suction head having a brush roller chamber with a bottom suction port, a pivotable port for a suction pipe, and a suction port connecting the brush roller chamber to the suction port, and a rotatably driven in the brush roller chamber and rotatably driven brush roller.
- the present invention seeks to provide a brush attachment with the features described above, which is characterized by good suction even at a low provided by the vacuum cleaner suction.
- this object is achieved in that the suction head in a leak test at a pressure loss of less than 10 mbar, the leak test with a according to EN 60312, version April 2001, standardized test device with hermetically sealed suction and a preset test vacuum of 100 mbar is carried out and for generating the negative pressure in the tester, a specific for the suction head household vacuum cleaner is used.
- the pressure loss is less than 8 mbar, and more preferably less than 5 mbar.
- the invention is based on the finding that in energy-saving vacuum cleaners with low suction power, the leaks of a suction head over a corresponding loss of air flow much more negative negative impact as in vacuum cleaners with high suction power.
- the brush attachments known in the prior art show in the aforementioned test conditions pressure losses between 17 and 64 mbar, with an accumulation in the range of 30 to 60 mbar. Provided a high suction power, in these known devices, the loss of suction due to leaks can be compensated by the cleaning action of the brush roller. However, this is no longer the case with vacuum cleaners with low suction power, so that here the high pressure loss is not acceptable.
- the suction head is composed of several parts, which are partially fixed together and partially relatively movable connected to each other. The compounds are to be formed so dense that the pressure loss according to the invention of less than 10 mbar is achieved. By the present invention very dense formed brush attachment is still guaranteed a satisfactory cleaning effect even with small suction power of the household vacuum cleaner.
- the brush roller may be driven by an electric motor or by a turbine rotating in the suction air flow.
- brush attachments which have a turbine for driving the brush roller
- even a deliberately generated leakage in the form of rigid or operable secondary air openings is provided.
- These secondary air openings are used to ensure a sufficiently large air volume flow for the drive of the turbine and thus the brush roller even when sucking carpets with dense pile.
- this design is unacceptable because the air drawn in by the secondary air openings consumes too much of the suction power.
- According to the invention therefore another approach by using a particularly dense brush attachment, which achieves the desired cleaning effect even with low vacuum cleaner performance.
- the suction head may also have a flow through the suction air flow elastic hose or bellows, which connects the housing of the suction head with the pivotally mounted thereon Saugrohran gleich.
- the suction pipe connection sealing lips made of an elastomeric material which abut sealing surfaces of the hinge connection.
- the test apparatus 1 has a measuring box 2 in the form of a hollow cube with an edge length of approximately 500 mm ⁇ 500 mm ⁇ 500 mm.
- the measuring box 2 has a nozzle for connecting a vacuum cleaner 3 for generating a negative pressure in the measuring box 2.
- a pressure measuring device 4 is connected to determine the pressure loss.
- the measuring box 2 further has a connecting piece for a suction pipe 6, to which a brush attachment to be tested can be connected.
- the structure shown in Fig. 1 a is used to set the preset test vacuum of 100 mbar, which is achieved via a corresponding adjustment of the suction blower power of the connected vacuum cleaner 3.
- the suction pipe 6 connected to the measuring box 2 is hermetically sealed at the end with a cap 7.
- P ambient designates the ambient air pressure outside the measuring chamber.
- the brush attachment shown by way of example in FIGS. 2 to 4 comprises a suction head 8 which has a brush roller chamber 9 with a bottom-side suction opening 10, a pivotable connection 11 for the suction pipe 6 and a suction channel 12 connecting the brush roll chamber 9 to the suction pipe connection 11.
- the Saugrohran gleich 11 is pivotally inserted into the housing 23 of the suction head 8 and forms with the housing 23 a Kippgelenkharm 21.
- the brush attachment has a rotatably mounted in the brush roller chamber 9 and rotatably driven brush roller 13 and is further equipped with rollers 14.
- the suction port 10 is hermetically sealed by a corresponding attachment 15.
- the suction head 8 of the brush attachment which was stored for at least two hours at the outside of the measuring box 2 prevailing ambient temperature T environment prior to performing the test, as shown in FIG. 1 b, is pivoted back and forth during the leak test by corresponding pivoting movements of the suction pipe connection 11 (see. also Fig. 2).
- the highest measured value p 2 found during the test is used to calculate the pressure loss ⁇ p, which at a Brush attachment according to the invention is less than 10 mbar.
- the vacuum cleaner 3 connected to the measuring box 2 for generating the negative pressure is a household vacuum cleaner, which is intended for the brush attachment to be tested and to which the suction pipe connection 11 of the examined suction head 8 can be connected.
- Figs. 2 to 4 show various embodiments of the brush attachment according to the invention.
- the suction channel 12 each includes a turbine chamber 16, in which a turbine 17 rotatably driven by the suction air flow is rotatably mounted, which serves to drive the brush roller 13 via a belt 18.
- a turbine 17 rotatably driven by the suction air flow
- the suction channel 12 each includes a turbine chamber 16, in which a turbine 17 rotatably driven by the suction air flow is rotatably mounted, which serves to drive the brush roller 13 via a belt 18.
- leaks have a negative impact even in two respects.
- the negative pressure and thus the suction air flow at the intake opening 10 are reduced by the leakage.
- the drive power of the turbine 17 and thus the cleaning effect of the brush roller 13 are reduced due to the reduced suction air flow.
- the particularly low pressure loss according to the invention has a positive effect on the cleaning effect of turbo brush attachments in two respects. From Fig.
- FIG. 3 shows a suction head 8 with an elastic bellows 20 through which the suction air flow flows, which connects the housing 23 with the suction pipe connection 11 mounted pivotably on it.
- the bellows 20 surrounds the turbine 17. In this way, a pressure loss due to leaks between the sliding surfaces of the articulated connection 21 is effectively prevented.
- an elastic hose may be provided.
- the suction pipe 11 is provided with sealing lips 22 made of an elastomeric material, which bear against sealing surfaces of the joint 21.
- Fig. 5 shows the determined under the specified test conditions pressure loss of a brush attachment according to the invention compared to the prior art. Show it the map A the working area, fall into the inventively designed brush attachments, the map B is the area in which brush attachments of the prior art fall whose brush roller is driven by an electric motor, the map C is the area in which brush attachments of the prior art fall whose brush roller is driven by an air turbine, the map D is the area in which prior art brush attachments fall for pad surfaces whose brush roller is driven by an air turbine.
- the maps B to D do not show the range of a single brush attachment but illustrate the area in which fall under the standardized test conditions determined pressure losses of known brush attachments.
- Charts B and C refer to brush attachments for cleaning floor surfaces. While the brush attachment according to the invention has a pressure drop of less than 10 mbar at a preset test vacuum of 100 mbar, the corresponding values of the brush attachments known from the prior art are significantly higher.
