DETAILED DESCRIPTION OF THE DRAWINGS
[0047] In the figures, identical and similar components are denoted by the same reference signs.
[0048] FIG. 1 shows a preferred configuration of the arrangement of a de-dusting unit (1) in a vacuuming device (not represented). In particular, FIG. 1 shows a first filter (4) and a second filter (5), which together with a turbine (3) enclose a vacuum chamber (2) in the interior of the vacuuming device. In the exemplary embodiment of the invention that is represented in FIG. 1, the filters (4 and 5) are arranged in a linear solution, which is preferably characterized in that the filters (4 and 5) are arranged substantially parallel to one another in a lower region of the vacuum chamber (2). Arranged in the vacuum chamber (2) is a preferably movably configured de-dusting unit (1), which comprises an eccentric unit (9), and also a first tappet (10) and a second tappet (12). In addition, the vacuum chamber (2) is surrounded by side walls, which connect the turbine (3) and the filters (4 and 5) to one another. The eccentric unit (9) preferably has two eccentrics (7 and 8), which can preferably rotate in the same direction, but with an offset of 180° in relation to one another. This mutually offset rotation of the preferably two eccentrics (7 and 8) allows the centrifugal forces that are produced by the rotational movements of the eccentrics (7 and 8) to compensate for one another. The rotational movements of the eccentrics (7 and 8) advantageously have the effect of producing a torque, with which for its part oscillating movements can be produced. These oscillating movements can be transmitted by the tappets (10 and 11) to the filters (4 and 5) of the vacuuming device, whereby a de-dusting of the filters (4 and 5) is brought about. In particular, the tappets (10 and 11) are designed to close off the inlets (12 and 13) of the filters (4 and 5) with respect to the vacuum chamber (2). This air-tight or pressure-tight termination is preferably referred to for the purposes of the invention as isolation of the filters (4 and 5) from a suction flow within the vacuum chamber (2) of the vacuuming device. Preferably, the first tappet (10) can close the first filter inlet (12), whereas the second tappet (11) is designed to close the second filter inlet (13). In the arrangement of the de-dusting unit (1) that is represented in FIG. 1, the de-dusting unit (1) is in a middle position, in which both filters (4 and 5) are available for the cleaning of the air in the suction flow and in which no filter de-dusting takes place. The de-dusting unit (1) can be transferred by a displacement module (6) from the middle position into a first de-dusting position (see FIG. 2) or into a second de-dusting position (see FIG. 3). For this purpose, a vertical movement (“linear solution”) or a rotational movement (“rotary solution”) of the de-dusting unit (1) is brought about by means of the displacement module (6).
[0049] Also represented in FIG. 1 are elastic suspensions (14), which can preferably be used to fasten the filters (4 and 5) within the vacuuming device. Between the eccentrics (7 and 8) there may be arranged a drive device (15), with which the two eccentrics (7 and 8) can be driven.
[0050] FIG. 2 shows a de-dusting unit (1) in a first de-dusting position, in which the first filter (4) is de-dusted. In this position, the first tappet (10) closes the inlet (12) of the first filter (4) and thus separates it from the vacuum chamber (2). This isolation is preferably achieved by a form fit. In the time period in which the first filter (4) is isolated from the suction flow in the vacuum chamber (2) by the first tappet (10), a de-dusting of the first filter (4) can be advantageously carried out, the first filter (4) not being available in this time for the cleaning of the air of the suction flow in the vacuum chamber (2). In particular, the de-dusting unit (1) is moved from one position into another position by the displacement module (6). This change of position preferably takes place by a vertical movement or a rotational movement of the de-dusting unit (1).
[0051] In the first de-dusting position, the oscillating movements that are produced by the rotational movements of the eccentrics (7 and 8) can be transmitted to the filters (4 and 5) by means of the tappets (10 and 11), whereby the filters (4 and 5) are de-dusted. The tappets (10 and 11) may have a rounded front side, in each case facing a filter (4 or 5) or a filter inlet (12 or 13). On the side facing the eccentric unit (9), the tappets (10 and 11) preferably have planar undersides, which are arranged substantially parallel to the side walls of the eccentric unit (9).
[0052] FIG. 3 shows a de-dusting unit (1) in a second de-dusting position, in which the second filter (5) is de-dusted. In this position, the second tappet (11) closes the inlet (13) of the second filter (5) and thus separates it from the vacuum chamber (2). In the time period in which the second filter (5) is isolated from the suction flow in the vacuum chamber (2) by the second tappet (11), a de-dusting of the second filter (5) can preferably be carried out, the second filter (5) not being available in this time for the cleaning of the air of the suction flow in the vacuum chamber (2).
[0053] FIG. 4 shows a representation of a preferred embodiment of the provided arrangement of the de-dusting unit (1) and the filters (4 and 5) according to a so-called rotary solution. In the context of the rotary solution, the de-dusting unit (1) is designed to carry out a rotational movement about a point of rotation (18). In this case, this movement is preferably brought about by the displacement module (6) of the vacuuming device. In the exemplary embodiment of the invention that is represented in FIG. 4, the de-dusting unit (1) is connected to the second filter (5) by way of the displacement module (6) and the connecting means (18). In particular, the de-dusting unit (1) is connected to an inner side component (16) of the second filter (5). Preferably, the inlets (12 and 13) of the filters (4 and 5) are formed by side components (16 and 17). These side components (16) may lie opposite one another and be formed substantially parallel to one another. The other side component (17) respectively of the filter inlets (12, 13) may preferably be referred to for the purposes of the invention as the outer side component (17). Within the rotary solution, the filters (4 and 5) may be arranged obliquely in relation to one another in the vacuuming device. For example, the second filter (5) may form an angle of inclination alpha with an imaginary horizontal plane, whereas the first filter may form an angle of inclination beta with the imaginary horizontal plane, the angles of inclination preferably being linked together by way of the relationship «beta=180°−alpha».
[0054] FIG. 4 shows a middle position of the de-dusting unit (1) within the vacuum chamber (1) of the vacuuming device, in which both filters (4 and 5) are open with respect to the vacuum chamber (2). The suction flow can consequently flow through both filters (4 and 5) and can be advantageously cleaned by the filters (4 and 5).
[0055] FIG. 5 shows a de-dusting unit (1) in a first de-dusting position, in which the first filter (4) is de-dusted, wherein, according to a rotary solution, the filters (4 and 5) are preferably arranged obliquely in relation to one another. The first tappet (10) in this case closes the first filter inlet (12), this isolation preferably being achieved by a form fit. For this purpose, a connection is preferably formed between the first tappet (10) and the side components (16 and 17), which form the inlet (12) of the first filter (4).
[0056] FIG. 6 shows a schematic representation of possible eccentric positions and arrangements within the vacuum chamber (2) of the vacuuming device. In particular, FIG. 6 shows four customary positions that the eccentrics (7, 8) of the eccentric unit (9) of the de-dusting unit (1) can assume. Sub-figure 1 (top left) shows the configuration of the eccentrics (7, 8) “longitudinal axis outward”, in which the centrifugal forces (20) of the eccentrics (7, 8) are preferably directed outwardly in the same axis, so that they advantageously compensate for one another or cancel one another out. Sub-figure 2 (bottom left) shows the configuration of the eccentrics (7, 8) “transverse axis clockwise”, in which the centrifugal forces (20) of the eccentrics (7, 8) advantageously produce or initiate a torque (19) in the clockwise direction, the torque (19) preferably also being referred to for the purposes of the invention as the rotational force or de-dusting force. Sub-figure 3 (top right) shows the configuration of the eccentrics (7, 8) “longitudinal axis inward”, in which the centrifugal forces (20) of the eccentrics (7, 8) are preferably directed inwardly in the same axis, so that they once again advantageously compensate for one another. Sub-figure 4 (bottom right) shows the configuration of the eccentrics (7, 8) “transverse axis counterclockwise”, in which the centrifugal forces (20) of the eccentrics (7, 8) are arranged in relation to one another in such a way that a torque (19) in the counterclockwise direction is produced or initiated, it being possible for the torque (19) to be used for producing the oscillating movement and for de-dusting the filters (4, 5) of the vacuuming device.
