Abstract

The invention relates to a self-propelled or traversable sweeper (1) with a sweeping brush (6) and an associated dirt collecting space (9). In order to design a sweeper of the type in question to the effect that this allows complete cleaning compared with the known devices, a liquid application device (10) is proposed, which is arranged in the direction of travel (r) behind the sweeping brush (6) and a further Behind arranged dehumidifying device (17).

Description

  • The Invention relates first a self-propelled or traversable sweeper with a sweeping brush and an associated dirt collecting space.
  • Sweepers of the type in question are known. So is in the DE 4414 683 A1 a sweeping machine is described and illustrated, which is provided with a device for receiving dust, debris or the like from a surface to be cleaned with sweeping brushes and a receiving chamber for recorded dirt. This sweeping device can be interconnected with a suction device for emptying the receiving chamber. Furthermore, the sweeping device known from the aforementioned patent application is designed as a hand-held or stalk-guided device having an electric motor for driving the sweeping brushes. In addition, self-propelled sweeping devices such as sweeping robots are known which autonomously work larger surfaces, especially hard surfaces clean with sweeping brushes and keep the collected dirt in a recording. In this regard, for example, on the DE 102 42 257 A1 directed.
  • in the With regard to the prior art described above, a technical problem of the invention seen in it, a sweeper in speech to improve the way that this across from the known devices a complete Cleaning possible.
  • This object is achieved first and foremost by the subject matter of claim 1, wherein is placed on a liquid applicator, which is arranged in the traversing behind the sweeping brush and a further behind arranged dehumidifying device. As a result of this embodiment according to the invention, complete cleaning, in particular of hard floors, is made possible. Experience has shown that conventional sweeping of such hard floors does not result in complete cleaning. Rather, often a subsequent damp mopping of the hard floor is required. The sweeper according to the invention offers the possibility to follow the sweeping a damp mopping. It is thereby possible a complete hard floor cleaning in a single operation. This user-friendly solution replaces the usual multiple operations with different devices and set-up times. Next, the inventive design of the sweeping device is conceivable both in autonomously working sweeping devices, such as sweeping robots and hand or stalk guided sweeping. The individual components of the sweeping device - sweeping device, liquid application device and dehumidifying device - preferably work simultaneously. It is also conceivable, however, a solution in which individual modules can be added as needed. The specified inventive solution also results in a novel method for cleaning hard floors, especially in the household sector, wherein in a single operation initially swept, thereafter a liquid application to the hard floor and finally the recording of the liquid particles offset with dirt particles. A cleaning of hard floors is carried out according to this embodiment without long set-up times, without body contact to dirt or cleaning fluid, as is the case for example in the usual wet wiping and recording, and with little physical effort. Furthermore, sweeping and damp cleaning of overground surfaces and, for example, vertical surfaces such as wall tiles, shower cubicles or the like is also possible by means of the sweeping device according to the invention. In order to achieve a further improved cleaning result, it is provided that a cleaning roller is arranged in front of the dehumidifying device, by means of which the soil moistened by the liquid application device is mechanically processed. So even stubborn dirt on the hard floor can be eliminated in one operation. The cleaning with such, preferably driven by electric motor rota-generating cleaning roller leads without multiple forward and backward movement of the sweeper over the area to be cleaned to very good results. The cleaning roller is preferably covered with a cleaning cloth. Alternatively, the cleaning roller may also be a bristle roller. In order to achieve a significantly greater mechanical cleaning work compared to a simple sweeping over a soiled spot with a conventional wiper or the like, it is further provided that the cleaning roller rotates with a relative to the travel speed of the sweeper higher relative speed relative to the ground. For example, with a cleaning roller diameter of 40-60 mm, a rotational speed of the cleaning roller of more than 500 rpm, such as about 1000 rpm, is given. The liquid application device arranged behind the sweeping brush in the direction of travel serves to wet the soil with cleaning liquid, for which purpose the liquid application device preferably has a metering gap oriented transversely to the direction of travel. Also conceivable is an embodiment in which the liquid application device is formed by a plurality of application nozzles arranged side by side transversely to the direction of travel. The liquid output can be gravity assisted by opening and closing a valve. It is also conceivable one Embodiment in which the liquid is dispensed by pumping, such as by arranging a metering pump, such as a mini-diaphragm pump. The targeted application of a small amount of cleaning liquid for wetting the soil is sufficient. Thus, the order is preferably from 0.25 to 1 liter, more preferably 0.5 liter per 10 m 2 . As a result, the fresh water tank and possibly provided waste water tank can be dimensioned relatively small. In order to be able to apply more cleaning fluid to heavily soiled areas as required or to apply a lower dosage amount to sensitive hard floors such as parquet or laminate, it proves to be expedient that the output quantity can be adjusted. The remaining on the ground dirty water is finally taken up by the Ent moisturizer, the latter may be a suction device. Such a suction device is provided with a, an air flow generating suction / blower motor and a shutdown sheath. Preferred is an embodiment in which the dehumidifying device is designed as a wipe. Such a wipe may in this case be a cloth which is stretched in the bottom area of the sweeper. In a preferred embodiment, it is provided that the wipe is arranged circumferentially. Such, in particular very slowly wraparound wipe can be used much longer, as this can absorb more liquid than a bottom-mounted wiper due to its greater length. In addition, the wraparound wipe can be dehumidified by squeezing, whereby the liquid emerging in this case is taken up in a collecting container. For this purpose, for example, two rollers are provided, between which the wipe is moved through. In a further preferred embodiment of the subject invention, the sweeping device is operated via an accumulator, which proves to be particularly advantageous in a self-propelled sweeper, such as a sweeping robot, but also in a hand or stalk guided sweeping. About the accumulator, both the rotating sweeping brush and the cleaning roller and the dehumidifying device, in particular the rotating wipe is driven, further, for example, via an integrated electronics dosing of the liquid output is adjustable. This electronics can be used to trigger the pump or valve to dispense the liquid at intervals adjusted to the desired dosage. Furthermore, the arrangement of a known dirt sensor is conceivable, in particular in an autonomously operating sweeper, by means of which the output quantity of the liquid is automatically adapted according to the determined degree of soiling of the hard floor to be cleaned. The coarse dirt pickup in the direction of travel before the liquid application device arranged sweeping brush takes place in a known manner by the motorized sweeping brooms conveyed loose dirt on a dirt ramp in a dirt container, such as a snail shell-shaped container. This dirt container can either be removed and emptied after the cleaning process or vacuumed with the help of a vacuum cleaner. In this regard, the above-mentioned DE 4414 683 A1 Reference is hereby made, the content of which is hereby incorporated in full into the disclosure of the present invention, also for the purpose of including features of this patent application in claims of the present invention.
  • The invention also relates to a combination of a sweeping device, in particular a sweeping device as described above, in an embodiment of a self-propelled sweeping device with a base station, in which the sweeping device resides when not in use, such as for recharging of accumulators. A generic combination of a self-propelled sweeper with a base station is from the above-mentioned DE 102 42 257 A1 known. The base station described therein is used in addition to the recharging of batteries and the emptying of the dirt collection container in which the corresponding dirt receptacle is sucked by means of a separate vacuum cleaner. The content of this patent application is fully incorporated into the disclosure of the present invention, also for the purpose of including features of this patent application in claims of the present invention.
  • To further improve a generic combination, it is proposed that a cleaning device for the sweeping brush and / or for the dehumidifying device is provided in the base station. Such a cleaning device can also be used in dry sweepers as known from the prior art described above. In addition, however, also in a sweeper, which downstream of a dry machining has a wet processing device according to the invention described above. Thus, in an advantageous manner during a parking position of the sweeping device in the base station optionally in addition to charging the device-side accumulator, a cleaning of the tillage devices of the device. As a result, any adhering dirt residues on the sweeping brush and / or on the dehumidifying device are advantageously removed in the parking position of the device. It is also proposed that a cleaning device for the cleaning roller is provided in the base station. It is further proposed that the cleaning device consists of a cleaning brush, wherein further a plurality of cleaning brushes are provided, which associated with the individual Cleaning components of the device interact with these. In any case, the cleaning brush partially immersed in a cleaning liquid or is wettable with such, according to which a wet cleaning of the cleaning components of the device is feasible. It is also proposed that the cleaning device is arranged in the bottom of a receiving space of the base station for the sweeping device, for example in the form of an underfloor cleaning device, wherein a plurality of cleaning brushes are arranged in a, a cleaning liquid-storing trough, which trough of the device under randseitiger support thereof is run over. It is also conceivable in this regard that the trough of the cleaning device is only opened during the startup of the device on the base station and automatically closes when leaving the base station. Another advantage of the solution according to the invention is that a liquid reservoir is provided in the base station for filling a tank of the sweeper. This sweeper tank stores a cleaning fluid used for damp cleaning a hard floor. According to the invention, this tank is refilled in the parking position of the device via the station-side liquid reservoir. This filling can be automated, for example by docking the device-side tank to the liquid reservoir. The device-side tank can for this purpose have a self-closing valve. It also proves to be advantageous in this regard that a receptacle for dirty water is provided in the base station. Thus, in the parking position of the device in the base station, the container receiving the collected dirty water is more preferably automatically emptied, for example, by docking and gravity assisted.

  • The autonomously working sweeper 1 has two electric motor driven Verfahrräder 4 on.
  • In the direction of travel r is a front transverse to the direction r erstrekkende, electric motor driven sweeping brush 6 arranged, which serves the coarse dirt absorption. This is done by mechanical brushing of the hard floor to be cleaned 7 by means of the sweeping brush 6 , wherein the dirt particles over a in the direction of travel r behind the sweeping brush 6 arranged dirt ramp 8th in a dirt collection room 9 to get promoted. The latter and the passing in this dirt ramp 8th are in cross-section as shown in FIG 3 shaped snail shell, so that in the dirt collection room 9 absorbed dirt can not escape automatically again.
  • Furthermore, behind the sweeping brush 6 or the dirt ramp 8th - Considered in the direction of travel r - a liquid applicator 10 intended. This has a tank 11 for storing a cleaning liquid, which in the area of the sweeping brush 6 and the dirt ramp 8th interspersed chassis floor 12 in a transversely directed to the direction of travel r metering 13 empties. This metering gap 13 is over a valve 14 openable and closable.
  • The liquid is dispensed after opening the valve 14 gravity-assisted. Also conceivable is an embodiment in which the liquid is supplied via a metering pump. Next, a dosage of Flüssigkeitsaus administration is provided. This dosage can be done manually via a regulator. In connection with an optionally provided dirt sensor of the Kehrge Raets 1 , By means of which a degree of contamination of the hard floor to be cleaned 7 can be determined, the dosage can also be done using an electronic evaluation.
  • In the direction of travel r is the liquid applicator 10 downstream of a cleaning roller 15 provided, which is equal to the sweeping brush 6 extends transversely to the direction of travel r and is rectified with respect to their direction of rotation to the sweeping brush 6 , In the in the 3 The embodiment shown is the cleaning roller 15 around a bristle roller for mechanical brush processing of the liquid applicator 10 moistened hard floor 7 ,
  • The rotational speed, in particular of the cleaning roller 15 is chosen so that this with a compared to the traversing speed of the sweeper 1 higher relative speed compared to the hard floor 7 circulates. So rotate both the cleaning roller 15 as well as the sweeping brush 6 preferably at a speed of about 1000 rpm.
  • As in the embodiment as shown in FIG 4 shown, the cleaning roller 15 also with a cleaning cloth 16 be covered.
  • In the direction of travel r concluding is a dehumidifier 17 intended to receive the on the hard floor 7 located dirty water. This dehumidifying device 17 may be a suction device, including in the sweeping device 1 an unillustrated suction fan is arranged. This is associated with a liquid separator.

  • Alternatively, as in 4 shown, the dehumidifying device 17 from a wraparound wipe 18 , which is driven by an electric motor in a vertical plane around pulleys 19 is guided. The rotational speed of this endless wipe is set low. This alternative solution can be used much longer, as such a wraparound wipe 18 due to its greater length can absorb more liquid.
  • The wraparound wipe 18 is dehumidified by squeezing, including two additional rolls 20 are provided, between which the wipe 18 is performed. By means of these rollers 20 will the wipe 18 wrung out, with the leaking liquid in a collecting container 21 is recorded.
  • It is further preferred as in 4 shown that the wraparound wraparound 18 over a relatively large contact area over the hard floor 7 for receiving the dirty water is performed.
  • By means of the inventive series arrangement of a coarse dirt pickup - formed by sweeping brush 6 and dirt collection room 9 - A liquid applicator 10 , a cleaning roller 15 and a final dehumidifier 17 In one device, a simplified and also hygienic complete cleaning of a hard floor can be achieved. In particular, due to the fact that initially a coarse dirt pickup is done by sweeping, only a relatively low liquid application is required for subsequent wet cleaning with conventional contamination. Thus, in a preferred embodiment, about 1 liter of cleaning fluid is sufficient for an area of about 20 square meters to be cleaned. The tank can be correspondingly small 11 as well as the collection container 21 be dimensioned, which in turn leads to a compact design of the sweeper 1 leads.
  • The electric motors for the sweeping brush 6 , the cleaning roller 15 as well as for the drive for the wiping cloth 18 be over a merely schematically illustrated accumulator 22 operated, via which also a power supply of a control unit, for example, to control the valve 14 in the dosing gap 13 can be achieved.
