Definitions
- Dirt collecting device for a cleaning appliance in particular a sweeping vehicle and vacuum cleaner nozzle for a vacuum cleaner and method for operating both devices
- the invention relates to a Schmutzsammeivorraum for a cleaning device, in particular a sweeping vehicle and a vacuum cleaner nozzle for a floor or vacuum cleaner and a method for operating both devices.
- a dirt collecting device for a sweeping vehicle has been described, for example, with the subject matter of DE 32 13 089 A1 or DE 103 56 419 B3 or DE 198 51 666 C1. All embodiments and functions described therein are part of the present invention description. It follows that a dirt collecting device for a sweeping vehicle can only have a front or bottom side operated sweeping roller, but also additional front in the front sweeping rollers, as described in DE 32 13 089 A1 by the reference numeral 10.
- the invention relates to a vacuum cleaner nozzle for a floor or upright vacuum cleaner, as for example with the subject of the
- a flow rate in the range of 30 to 40 liters per second is required for effective cleaning of hard floors, resulting in a power ranging between 900 to 1500 watts of an associated suction fan.
- the high volume flow is necessary to allow an air velocity of between 15 and 30 m / s in the area of the ground-based dirt collecting device.
- the respective arranged in the front sweeping roller serves to replace coarse and fine dirt from the surface to be cleaned.
- the present invention claims both directions of rotation of such sweeping roller. Accordingly, such a sweeping roller operating both in union operation, as well as work in Untersch. There is a need to reduce the energy consumption of such cleaning machines with Schmutzsammeivorraumen.
- the example of the sweeper according to the subject of DE 198 51 666 C1 can be explained that for receiving coarse dirt, which consists mainly in the field of street sweepers from empty glass bottles, stones and other heavy objects, a suction of the suction fan in the range between 2 to 5 kW is required.
- the coarse dirt collecting container according to DE 198 51 666 C1 filled, it can be pulled out and must be emptied manually. Only after repeated insertion, the sweeper can continue to operate. Thus, operation of such a sweeping vehicle is possible only in intermittent operation, i. The sweeping vehicle has to stop now and then and emptying the coarse dirt collecting tank at a suitable place, which encounters difficulties with branched road networks in big cities.
- the brush roller used on the front is designed so that it has to promote the recorded from the bottom side coarse and fine dirt on an elevated conveyor line in a downstream container, which is associated with an increased suction pressure and unwanted noise emission.
- the brush roller fails to promote the recorded coarse dirt in the form of stones or other heavy, non-airworthy objects in the downstream collection container. Accordingly, even with such vacuum cleaner nozzles has the disadvantage that the performance of the suction fan must always be chosen so high that even heavy, recorded items must be made airworthy due to the applied suction to be transported in a downstream collection container, resulting in high energy consumption and an undesirable noise emission of the suction fan has the consequence.
- the invention is therefore based on the object, a method for operation and a Schmutzsammeivoriques for a cleaning vehicle, in particular a sweeper or a vacuum cleaner for a floor or vacuum cleaner of the type mentioned in such a way that the suction fan used for this purpose with significantly lower energy consumption and lower noise emission is working.
- a device is characterized by the subject-matter of independent claims 1 or 5, and both devices are operated by a method according to independent claim 7.
- Feature of the invention is therefore that both a Schmutzsammeivoriques, as well as a vacuum cleaner nozzle is proposed, in the housing - substantially at the same level or only slightly increased - to the plane on which the male coarse or fine dirt stores, an intermediate container is connected downstream , which is intended for the temporary storage of temporarily non-airborne coarse dirt.
- the invention provides that in the housing of the Schmutzsammeivoriques for a cleaning device, in particular a sweeping vehicle or in the housing of a vacuum cleaner nozzle, an intermediate container is integrated, which lies in the air flow of the suction fan and which is intended only - under the action of the present , reduced suction pressure non-airborne - to absorb coarse dirt, while the fine dirt immediately on this intermediate container away - even under the effect of reduced suction pressure - is transported to a repository designated collection container.
- the collection container provided on the end bearing side is divided in it. It can be formed from a coarse dirt container and a downstream fine dust container.
- the idea of the invention is to operate the suction fan in the cleaning device, in particular in the sweeping vehicle or the vacuum cleaner so that it only works with a reduced air speed, due to the reduced air speed only little energy is consumed by the suction fan. Accordingly, the noise level is reduced.
- the rotating driven sweeping roller can absorb the fine dirt and coarse dirt.
- the suction pressure is just enough to fill the intermediate container, which is arranged essentially at the same level or slightly elevated, with the non-flyable coarse dirt.
- the filling takes place on the one hand by the mechanical energy of the sweeping roller, which is only slightly supported by the reduced suction pressure.
- the fine dirt is conveyed (or removed) through the intermediate container at the reduced suction pressure and taken up in a downstream collection container arranged downstream of the final storage.
- a halving of the air flow in the area of the dirt collection device for a sweeper or for a vacuum cleaner nozzle means that the suction fan used requires only a quarter of the energy normally consumed. Therefore, during the largest period of operation of the dirt collector for a sweeper or the operation of a 0505
- Vacuum cleaner nozzle the suction power of the suction fan greatly reduced (normal operation), because the reduced suction power should just be sufficient to transport the recorded fine dirt in the end storage side designated collection container, while the recorded coarse dirt, which is not airworthy due to the low air velocity used and in an im Housing the dirt collecting device or the vacuum cleaner nozzle arranged intermediate container is added.
- the suction fan works only with its maximum energy consumption for the purpose of emptying the intermediate container of coarse dirt, which is now made airworthy by the increased air velocity and is transported to the downstream, the final storage tank.
- a sweeping vehicle with the dirt collecting device according to the invention for a very long period of time remain in continuous operation, because it is not necessary to emptying the coarse dirt collecting container intermittently, as was the case in DE 198 51 66 C1.
- the volume of the collecting container provided at the end bearing side is many times greater than the volume of the intermediate container, with a volume ratio of 1: 5 being preferred.
- one or more sensors are preferably arranged, which detect the level with coarse dirt.
- Such sensors can either operate without contact (optical, ultrasonic, inductive, capacitive) or even touching with suitable, spring-loaded sensors detect the level in the intermediate container.
- the maximum power of the suction fan requires a certain air speed, which is also referred to as transport speed, whose size is dependent on the weight and the dimensions of the deposits (coarse dirt) in the intermediate container. It is preferred if the Schmutzsammeivorraum used (including the front apron used) is closed on all sides in the direction of the road surface and only frontally has a nozzle-like narrowed receiving opening to increase the air velocity in this area again. This allows a high absorption capacity of the coarse dirt stored on the road surface.
- the area of the dirt collector for a sweeper located in the suction air flow of the suction fan should be between 20 and 100 x 10 "3 m2, for a vacuum cleaner nozzle, the area should be between 1 and 5 x 10 " 3 m2.
- the width of the front nozzle should be less than 50% of the width of the cleaning machine to allow the most effective dirt pick-up in the front area with high air velocities.
- the advantage of the intermediate container integrated in the dirt collecting device or in the vacuum cleaner nozzle is that only a low air flow is necessary in order to transport the dirt from the receiving plane into the dirt collecting device or the vacuum cleaner nozzle, because the largest delivery rate in this Activity of the rotating driven sweeping roller (a cleaning vehicle) or brush roller (a vacuum cleaner nozzle) takes place.
- the dirt collecting device is used for a sweeper with a reduced suction power of the suction fan in the range of 260 l / s for most of the operating time.
- the arranged in the intermediate tank level sensor thus controls the performance of the suction fan. It can also be alternatively provided a scheme in which the suction fan is controlled in function of the level in the intermediate container in its performance.
- the power of the suction fan is returned to the operating condition of z. B. 260 l / s reduced.
- a viewing window in the dirt collecting device for a sweeper or in a vacuum cleaner nozzle may be arranged, through which the operator can optically control the filling of the intermediate container.

- FIG. 1 schematically shows the air guidance in a sweeping vehicle, which is described for example with DE 41 28 879 A1 or EP 2 350 393 B1 is. All features described there, in particular the chassis, the steering, the drive and the like have been omitted for the sake of clarity in the figure 1 of the present invention description.
- the sweeping vehicle 1 according to FIG. 1 has a dirt collecting device 2 which consists essentially of a housing 26 (see FIG. 2) which is arc-shaped with respect to its top wall 27 and carries a height-adjustable front apron 15 at its front end.
- a dirt collecting device 2 which consists essentially of a housing 26 (see FIG. 2) which is arc-shaped with respect to its top wall 27 and carries a height-adjustable front apron 15 at its front end.
- the dirt collecting device 2 By means of a supporting device not shown in FIG. 1, the dirt collecting device 2 according to FIG. 1 can be moved over a roadway level 19, specifically via the traveling drive of the sweeping vehicle.
- a rotatably driven sweeping roller 14 In the interior of the dirt collecting device 2, a rotatably driven sweeping roller 14 is arranged.
- the front apron 15 is thus guided over the road surface 19 in the direction of travel 13 and the coarse dirt 17 stored there and a fine dirt 18 optionally stored there are absorbed.
- the coarse dirt 17 consists of a non-flyable in normal operation of the dirt collecting device 2 material such. As stones, bottles, cans and the like.
- the fine dirt 18, however, is immediately absorbed during normal operation of the dirt collecting device 2 and conveyed in the direction of arrow 21 via a connecting channel 3 in a downstream coarse dirt collecting 4.
- the output of the coarse dirt collecting container 4 is connected via a further connecting channel 5 with a fine dirt collecting container 6, so that the fine dirt reaches the filter 7, drops from there and is deposited in the fine dirt collecting container 6.
- a suction fan 8 is arranged, which is driven by a motor 9 via a drive shaft 11 in a certain direction of rotation.
- the motor 9 can either be an electric drive motor or it can also be derived directly from the drive of the sweeping vehicle 1 via a clutch and a corresponding intermediate gear.
- the fine dirt collecting container 6 can coincide with the coarse dirt collecting container 4 and both containers can form a single container.
- the suction power of the suction fan 8 is reduced so that only a reduced air flow in the front of the front skirt 15 and in the suction side of the sweeping roller 14, so that it is only possible with the reduced suction air that the sweeping roller 14 the coarse dirt 17 picks up from the road surface 19 and transported in Matterschtouch in the direction of arrow 20 (or alternatively in Untersch ist) in a subsequent to the sweeping roller 14, trough-shaped, upwardly open intermediate container 10. There, the coarse dirt is deposited, as shown in Figure 1. During normal operation, however, the recorded fine dirt 18 is transported over the intermediate container 10 away in the direction of arrow 21 either in the coarse debris collecting container 4 and / or in the downstream fine dirt collecting 6.
- the fine dust which may still be deposited in the coarse dirt collecting container 4, is still transferred to the fine dirt collecting container 6.
- both the coarse dirt collecting container 4, and the fine dirt collecting 6 can be emptied from time to time.
- FIGS. 2 to 5 show further details of the dirt collecting device 2 according to the invention.
- FIG. 2 shows that additional supporting and driving units 30 can be arranged on the dirt collecting device 2 so that they do not have to be fastened firmly to the sweeping vehicle 1 but separated and can only be operated via a coupling connection with the sweeping vehicle 1 in the direction of travel 13.
- FIG. 2 shows that the front apron 15 arranged at the front is pivotable in the direction of the arrow 34 and in the opposite direction in the region of a pivot axis 33 and extends with the front apron side Sealing lips 35 on the associated front wall 38 of the housing 26 of the dirt collecting device 2 sealingly applies.
- the voltage applied to the front wall 38 sealing lip 35 of the front apron 15 is arranged height adjustable in the arrow directions 36.
- a frame frame 16 is provided on the side of the housing, at the front free end of the pivot axis 33 is fixed for the pivotal mounting of the front skirt 15.
- the front apron 15 has in the region of the front intake opening a conical constriction 39, so that in the region of this intake opening, a high air velocity is created, which is capable of both the on-road layer 19 coarse dirt 17 and there stored fine dirt 18 at least in the work area to bring the rotating driven sweeping roller 14.
- the side walls of the front apron should be as sealed as possible on the road surface or form a small gap to the road surface.
- the area of the front apron 5 widens in the direction of the sweeping roller 14, which thus conveys the dirt received into an intermediate container 10 arranged in the housing 26 of the dirt collecting device 2, as shown in FIGS. 4 and 5.
- the intermediate container 10 has a bottom surface 41 which is separated from the working area of the sweeping roller 14 only by an inclined sloping rear cone wall 44, so that it is readily possible that the sweeping roller, even at low suction the coarse dirt 7 according to Figure 4 in Matternic, according to arrow 43 in the housing 26 arranged intermediate container 10 to convey.
- the housing 26 generally consists of a top wall 27 and two mutually parallel side walls 28, which are connected at the rear by a rear wall 29.
- a front wall 38 is arranged, to which the sealing lip 35 of the front apron 15 adjustable in height in the arrow directions 36 (see Figure 2 and Figure 4) applies a sealing.
- the front apron can pivot upwards and lying on the road surface 19 coarse dirt, z. B. a can according to Figure 4, is thus transported into the work area of the sweeping roller 14.
- the sweeping roller 14 forms a downwardly narrowed bottom receiving space 76 in which rests the prevailing in normal operation, reduced suction pressure.
- the suction pressure is essentially only suitable for transporting the fine dirt 18 into the intermediate container 10, and the coarse dirt is also brought substantially only in the working area of the roller brush 14 and transported by this according to arrow 43 in Matterkal in the intermediate container 10, where the Coarse dirt with the reference numeral 17 'in Figure 4 is shown.
- the intermediate container is bounded at the front by an inclined cone wall 44 (see FIG. 4), wherein the bottom surface 41 is approximately parallel to the road surface 19 and is closed at the rear by a settling wall 45, so that a sufficiently high filling level of coarse dirt 17 in the intermediate container 10 is possible is.
- FIG. It is shown in Figure 5, a maximum filling level 51 in the intermediate container 10 schematically, and it is further shown that the level sensor 49 with its measuring beam 50 scans the surface of the coarse dirt in the intermediate container 10 and generates a signal according to Figure 8 on reaching the maximum allowable filling level 51.
- such a level sensor 49 may also be replaced by horizontally measuring level sensors 49 ', which detect the filling level 51 in the intermediate container 10 laterally.
- mechanical scanning probes can also be used.
- FIG. 2 also shows, in connection with FIG. 3, that the supporting and driving units of the dirt collecting device 2 can consist of rollers 31 which are vertically adjustable in the direction of the arrow 32.
- the front apron 15 still has side, conically widening side skirts 37, and the housing 26 of the dirt collecting device 2 is preferably sealed at the bottom side opposite the road surface 19 or leaves only slight gaps open to a high suction pressure only in the area of the front apron 15th to produce, especially where the coarse and fine dirt 17, 18 is to be included.
- FIG. 3 further shows that the lateral boundaries of the intermediate container 10 preferably conically narrow in the direction of the suctioning connecting channel 3 and thus form cone walls 40.
- the sweeping roller 14 is mounted on a shaft 42 which is rotationally driven via a rotary drive, not shown.
- a rotary drive not shown.
- the receiving space 76 is closed for the operation of the sweeping roller 14 in the housing 26 at the back by a sealing wall 48 and then continues as an obliquely rearwardly directed cone wall 44.
- the fine dirt 18 received by the sweeping roller is taken along in the direction of arrow 47 in normal operation and does not settle in the intermediate container 10.
- Figures 6 and 7 now show the application of the principle of the invention to a vacuum cleaner 60, with the same explanations for the vacuum cleaner nozzle
- the vacuum cleaner 60 shown in the embodiment of the vacuum cleaner 60 shown in Figures 6 and 7 relates to a vacuum cleaner, which is described for example in US 5,500,979 A1.
- the vacuum cleaner nozzle 60 consists essentially of a housing 63 closed on all sides, which has a rear wall 66 and adjoining side walls 67, the front side of the vacuum cleaner nozzle 60 being closed off by a front wall 78.
- the upper side of the vacuum cleaner nozzle 60 is formed by a closed top wall 68.
- the brush roller 61 which is rotationally driven in a rotation axis 75.
- the brush roller 61 extends substantially transversely to the longitudinal axis through the
- Vacuum cleaner nozzle 60 and is occupied with individual brushes 74.
- the brush roller 61 operates according to Figure 7 in a receiving space 76 which is open towards a carpet pile 73 down.
- the carpet pile can be replaced by a hard floor surface.
- the suction pressure exerted by a suction fan (not shown in detail) (see US Pat. No. 5,500,979 A1), which is introduced into the housing 63 via the connecting channel 3, acts into the receiving space 76.
- the brushes 74 which are rotationally driven there, comb out the hard surface or carpet 73 which is to be cleaned and convey the coarse and fine dirt 17, 18 there in the direction of arrow 43 in the direction of the cap over the brush roller 61 into a downstream intermediate container 70.
- the vacuum cleaner nozzle 60 shown there is thus also in the same manner as shown with reference to Figures 1 to 5, designed as Schmutzsammeivorraum 62 and consists essentially of the rotationally driven brush roller 61, the detected in the receiving space 76 coarse and fine dirt after promotes in the rear of the housing in an intermediate container 70.
- the rotary drive of the brush roller 61 is shown in FIG.
- a motor 64 is used, which drives a belt drive 69 via its drive shaft 65, which runs over the brush roller 61 and drives it in rotation.
- the belt drive 69 is associated with a shaft 72.
- the intermediate container 70 is formed by a bottom surface 71, which is divided toward the front by an end wall 77. Although it is not shown in the drawing, it is provided that the end wall 77 is slightly increased, as has been described with the cone wall 44 in Figures 4 and 5 of the aforementioned embodiment.
- the intermediate container 70 is approximately trough-shaped and formed open at the top and is mainly intended for the inclusion of coarse dirt 17.
- coarse dirt in vacuum cleaner 60 nozzles of the type mentioned are z.
- small pebbles or other non-airworthy objects that can not be transported by the low, applied suction pressure in the downstream collection container. They are therefore deposited at the reduced suction pressure in normal operation in the intermediate container 70, and the level in the intermediate container 70 is monitored by a level sensor 49.
- the suction power of the suction fan is increased by about twice to three times compared to normal operation, so that the coarse dirt particles deposited in the intermediate container 70 in the direction of arrow 21 via the connecting channel 30 in a not closer shown, downstream repository-side collecting channel to convey.
- the negative pressure is chosen so even when plant of existing in normal operation, the negative pressure is so that the recorded fine dirt 18 is always transported in the direction of arrow 21 in the downstream, not shown collecting container.
- the intermediate container 70 is thus determined essentially only for temporary storage of the recorded coarse dirt 17 which is conveyed by the brush roller 61 in the direction of arrow 43 into the intermediate container 70.
- FIG. 8 now shows in schematic form that the fill level of the fill level sensor 49 in the intermediate container 10, 70 is monitored and when the fill level exceeds a certain maximum height, a sensor signal 52 is generated in the period between t1 and t2.
- FIG. 9 now shows that, as a function of the sensor signal 52 according to FIG. 8, the air speed of a suction fan 8 in a dirt collecting device 2 for a sweeping vehicle 1 is increased from a normal operation of 260 l / s, for example to 560 l / s.
- the coarse dirt 17 from the intermediate container 10 is able to fly and thus removed, and if the Level sensor 49 has indicated the emptying of the intermediate container 10, is transferred from the time t2 back to normal operation with reduced suction pressure. In the period between t3 and t4, another cleaning or emptying cycle of coarse dirt 17 takes place from the intermediate container 10.
- FIG. 10 shows that, by increasing the suction pressure in FIG. 5 in the emptying mode, the power of the suction fan has to be increased from about 1180 watts (normal operation) to about 3950 watts in order to achieve a sufficiently high air velocity in the period between t1 and t2 and in the period between t3 and t4.
- the dashed line shows averaged therefrom average energy consumption. It is important over the prior art that in Figure 10 of the prior art, a maximum power consumption of the suction fan of 3950 watts is always given and it is not intended that the energy consumption of the fan is lowered in normal operation to 1180 watts. It goes without saying that the energy consumption figures given here are variable within wide limits and depend on the performance of the suction fan. Important is only the ratio that just in normal operation, the suction fan only works with one third of the maximum power and this normal operation is maintained over a very long period of time until the intermediate container 10 is completely filled with coarse dirt 17 and the level sensor 49 this maximum level signaled.
- FIG. 11 shows, in an analogous manner, the energy consumption of a suction fan for a vacuum cleaner nozzle 60, in which it can also be seen that only the suction fan needs an energy of 250 watts in the period between 0 and t1 and only the suction power for emptying the intermediate container 70 of coarse dirt 17 is increased to a value of 900 watts.
- the specified wattages are to be understood only as an example, because it depends more on the ratio between the minimum energy consumption and the maximum energy consumption of the suction fan used.
- FIG. 13 shows that in a sweeping vehicle 1 with a dirt collecting device 2, the suction fan 8 used for this purpose is merely e.g. 0% of the operating time with a maximum energy of z. B. 3700 watts must be operated and operated in almost 100% of the operating time only with an energy consumption of 1100 watts.
- the consumption curve 53 shown there is only to be understood as an example, and the numerical values given are only given by way of example to illustrate the invention.
- the table in Figure 14 shows that in the discharge operation, the suction fan has an energy consumption of 3269 watts, while in normal operation, the fan only has an energy consumption of 480 watts, while the brushing power of the roller brush 14 is always at 700 watts of electrical power. In the peak, a power consumption of 3969 watts is thus specified in the emptying mode, while in normal operation, the suction fan only has an energy consumption of 1180 watts.
- the table in FIG. 15 shows the time proportion of the energy consumption of the suction fan for the dirt collecting device 2 of a sweeping vehicle 1 as a function of the operating time used. It can be seen that predominantly the sweeper with a suction fan of reduced power (90% time share with 1459 watts) is operated and only a discharge time of 10% of the operating time with an energy consumption of 3690 watts is charged. drawing Legend
