Description

Technisches GebietTechnical area

Die Erfindung betrifft ein Wischgerät mit einer Wischplatte auf der ein Wischbezug auswechselbar befestigbar ist.The invention relates to a mop with a mop plate on a mop cover is exchangeable fastened.

Stand der TechnikState of the art

Wischgeräte mit Wischplatten an denen Wischbezüge auswechselbar befestigbar sind, sind allgemein bekannt. Derartige Wischgeräte werden zur feuchten Bodenreinigung im häuslichen und gewerblichen Umfeld verwendet. Insbesondere bei der Bodenreinigung öffentlicher Gebäude ist neben der Effizienz der Reinigung insbesondere auch eine sichere Handhabung zu beachten. Bei einer hohen und effizienten Reinigungsleistung ist darauf zu achten, dass der Wischbezug stets eine ausreichend hohe Schmutzaufnahmekapazität aufweist. Die US 200710192979 A1 beschreibt einen visuellen Indikator zur Bestimmung der Reinigungswirkung und Nutzungsdauer eines Reinigungsgeräts. Aus der DE 42 44 433 C2 ist ein Wischgerät mit einer Wischplatte bekannt, wobei in die Wischplatte eine Messeinrichtung integriert ist. Die aus der Patentschrift bekannte Messeinrichtung erfasst den pH-Wert der Reinigungslösung die sich in dem auf der Wischplatte aufgespannten Wischbezug befindet. Es hat sich jedoch gezeigt, dass der pH-Wert stark von dem verwendeten Reinigungsmittel abhängt und daher ein Rückschluss auf den Schmutzgehalt nicht ohne weiteres möglich ist.Wipers with mop plates on which mops are replaceable fastened, are well known. Such wipers are used for wet floor cleaning in domestic and commercial environment. In particular, in the cleaning of public buildings, in addition to the efficiency of cleaning in particular safe handling must be observed.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, ein Wischgerät mit einer Messeinrichtung bereit zu stellen, welche mit einfachen Mitteln die verbleibende Reinigungsleistung des momentan verwendeten Wischbezugs anzeigt.The invention has for its object to provide a wiper device with a measuring device, which displays the remaining cleaning performance of the currently used mop cover with simple means.

Diese Aufgabe wird mit den Merkmalen von Anspruch 1 und 10 gelöst. Auf vorteilhafte Ausgestaltungen nehmen die Unteransprüche Bezug.This object is achieved with the features of claims 1 and 10. In advantageous embodiments, the dependent claims relate.

Zur Lösung der Aufgabe ist in die Wischplatte eine Messeinrichtung zur Detektierung der in dem Wischbezug vorhandenen Restfeuchte integriert. Im Zuge umfangreicher Untersuchungen hat sich herausgestellt, dass die verbleibende Reinigungsleistung und die Beladung des Wischbezugs mit Schmutz in einem direkten Zusammenhang mit der Restfeuchte des Wischbezugs stehen. Dies gilt insbesondere in Bezug auf hartnäckigen und anhaftenden Schmutz. Ein Wischbzeug weist auch bei geringer Beladung mit Reinigungsflüssigkeit ein gewisses Bindevermögen für Staub und ähnliche andere lose Verschmutzungen auf. Es hat sich aber gezeigt, dass sich ein ausreichendes Lösevermögen gegenüber anhaftenden Schmutz nur bei einer ausreichenden, das heißt einer höheren Beladung des Wischbezuges mit Reinigungsflüssigkeit ergibt. Das bedeutet, dass die Reinigungsleistung abnimmt, wenn sich nur noch wenig Reinigungsflüssigkeit in dem Wischbezug befindet. Je weniger Reinigungsflüssigkeit sich in dem Wischbezug befindet, desto weniger Schmutz kann in dem Wischbezug gebunden werden. In der Praxis wird oft eine visuelle Kontrolle der im Wischbezug noch verbleibenden Restfeuchte vorgenommen, wobei ein Kriterium für den Bezugwechsel oft das sogenannte Abreißen des Feuchtigkeitsfilms auf dem Boden ist. Dieses Kriterium lässt aber, abhängig vom Bodentyp und den Lichtverhältnissen, nur eine unzureichende Beurteilung zu. Die in die Wischplatte integrierte Messeinrichtung erfasst die in dem Wischbezug durch die Reinigungsflüssigkeit gebildetete Feuchtigkeit. Hierbei ist insbesondere vorteilhaft, dass es nicht unbedingt erforderlich ist, den Wischbezug zu modifizieren, da die Restfeuchte durch die Messeinrichtung direkt erfasst werden kann. Es können also beliebige bereits erhältliche Wischbezüge weiterhin verwendet werden. Die Messeinrichtung benötigt nur in geringem Umfang Energie, so dass die Energieversorgung durch eine in die Messeinrichtung integrierte Batterie oder durch einen Akku erfolgen kann. Bei Verwendung herkömmlicher Wischbezüge kann es erforderlich sein, die Messeinrichtung zunächst zu kalibrieren. Vorzugsweise umfasst die Messeinrichtung eine Einrichtung zur Mittelung von über einen vorgegebenen Zeitraum erfassten Messwerten auf, so dass eine kurze Unterbrechung des Kontakts zwischen Wischbezug und Wischplatte nicht zum Auslösen eines Signals führt.To solve the problem, a measuring device for detecting the residual moisture present in the mop cover is integrated into the mop plate. In the course of extensive investigations, it has been found that the remaining cleaning performance and the loading of the mop cover with dirt are directly related to the residual moisture of the mop cover. This is especially true in terms of stubborn and adherent dirt. A wiper has a certain binding capacity for dust and similar other loose soils even at low loading with cleaning fluid. However, it has been shown that a sufficient dissolving power against adhering dirt only results in a sufficient, that is a higher loading of the mop cover with cleaning fluid. This means that the cleaning performance decreases when there is only a small amount of cleaning fluid in the mop cover. The less cleaning fluid is in the mop cover, the less dirt can be bound in the mop cover. In practice, a visual check is often made of the residual moisture remaining in the mop cover, wherein a criterion for the change of cover is often the so-called tearing off of the moisture film on the floor. This Criterion, however, depending on the type of soil and the lighting conditions, allows only an insufficient assessment. The measuring device integrated in the mop plate detects the moisture formed in the mop cover by the cleaning fluid. It is particularly advantageous that it is not absolutely necessary to modify the mop cover, since the residual moisture can be detected directly by the measuring device. Thus, any already available mop covers can continue to be used. The measuring device requires only a small amount of energy, so that the power supply can be done by an integrated battery in the measuring device or by a battery. When using conventional mop covers, it may be necessary to calibrate the measuring device first. Preferably, the measuring device comprises a device for averaging measured values acquired over a predetermined period of time so that a brief interruption of the contact between mop cover and mop plate does not lead to the triggering of a signal.

Die Messeinrichtung kann mit einer Signaleinrichtung wirkverbunden sein. Die Signaleinrichtung kann akustische und/oder optische und/oder taktile Signale abgeben, wenn die Messeinrichtung einen vorgegebenen Schwellwert der in dem Wischbezug gebundenen Restfeuchte detektiert. Die Signaleinrichtung ist zur leichten Erkennbarkeit vorzugsweise auf der Oberseite, also der dem Wischbezug abgewandten Seite, der Wischplatte angeordnet. Die Signaleinrichtung kann auch am Stiel angeordnet sein oder durch Fernübertragung ausgelöst werden.The measuring device can be operatively connected to a signaling device. The signaling device can emit acoustic and / or optical and / or tactile signals if the measuring device detects a predetermined threshold value of the residual moisture bound in the mop cover. The signal device is preferably arranged on the upper side, ie the side facing away from the mop cover, of the mop plate for easy recognizability. The signaling device may also be arranged on a stick or triggered by remote transmission.

Die Messeinrichtung kann zwei voneinander beabstandete Kontaktflächen aufweisen, die mit dem Wischbezug in Berührung bringbar sind. Die Kontaktflächen sind auf der Unterseite, also der dem Wischbezug zugewandten Seite, der Wischplatte angeordnet und stehen mit dem Wischbezug in Kontakt.The measuring device may have two spaced-apart contact surfaces, which can be brought into contact with the mop cover. The contact surfaces are arranged on the underside, ie the side facing the mop cover, the mop plate and are in contact with the mop cover.

Die Messeinrichtung kann eine elektrische Kenngröße des Wischbezugs bestimmen. Derartige Messgrößen lassen sich besonders einfach bestimmen und es sind eine Vielzahl bekannter Messmethoden bekannt, um elektrische Kenngrößen zu bestimmen. Des Weiteren weisen die Materialien des Wischbezugs, meist Kunststoffe, grundsätzlich anderen elektrische Kenngrößen auf als Reinigungsflüssigkeit, meist Wasser mit einem Reinigungsmittel und Schmutzpartikel und stellen daher gute Indikatoren dar, um die Restfeuchte des Wischbezuges zu bestimmen.The measuring device can determine an electrical characteristic of the mop cover. Such measured variables can be determined particularly easily and a multiplicity of known measuring methods are known in order to determine electrical characteristics. Furthermore, the materials of the mop cover, usually plastics, fundamentally different electrical characteristics than cleaning liquid, usually water with a detergent and dirt particles and therefore are good indicators to determine the residual moisture content of the mop cover.

Die Messeinrichtung kann den elektrischen Widerstand des Wischbezugs bestimmen. Der elektrische Widerstand des Wischbezugs ist direkt von dessen Beladung mit Reinigungsflüssigkeit abhängig. Nach einer bekannten Messmethode wird der Wischbezug über die Kontaktflächen mit einer Gleichspannung oder einer niederfrequenten Wechselspannung mit weniger als 50 Hz beaufschlagt, wobei sich der elektrische Widerstand des Wischbezugs proportional zum gemessenen elektrischen Strom verhält. In einer anderen Ausführung kann auch der elektrische Leitwert des Wischbezugs bestimmt werden. Der elektrische Leitwert ist der Kehrwert des elektrischen Widerstandes. Dieser kann durch Beaufschlagen des Wischbezugs mit einer höherfrequenten elektrischen Wechselspannung von mehr als 50 Hz bestimmt werden. Beide Messmethoden sind vergleichsweise einfach.The measuring device can determine the electrical resistance of the mop cover. The electrical resistance of the mop cover depends directly on its loading with cleaning fluid. According to a known measuring method, the mop cover is subjected to a DC voltage or a low-frequency AC voltage of less than 50 Hz via the contact surfaces, the electrical resistance of the mop cover being proportional to the measured electric current. In another embodiment, the electrical conductivity of the mop cover can also be determined. The electrical conductance is the reciprocal of the electrical resistance. This can be determined by applying the mop cover with a higher frequency electrical AC voltage of more than 50 Hz. Both methods of measurement are comparatively simple.

Die Messeinrichtung kann die Permittivität des Wischbezugs bestimmen. Die Permittivität, der Kapazitätswert, ist ein Wert für die Durchlässigkeit eines Materials für elektrische Felder. So weist Polypropylen, ein häufig für Wischbezüge verwendetes Material eine Permittivität von etwa 2 und Wasser eine Permittivität von 80 auf. Eine hohe Beladung des Wischbezugs mit Wasser bedeutet demnach auch eine höhere Permittivität als ein unbeladener Wischbezug.The measuring device can determine the permittivity of the mop cover. The permittivity, the capacitance value, is a value for the permeability of a material for electric fields. For example, polypropylene, a material commonly used for mop covers, has a permittivity of about 2 and water has a permittivity of 80. A high loading of the mop cover with water therefore also means a higher permittivity than an unloaded mop cover.

In den Wischbezug können weitere Kontaktflächen integriert sein. Die weiteren Kontaktflächen sind vorzugsweise elektrisch leitend mit den Kontaktflächen der Wischplatte wirkverbunden und verbessern dadurch das Messergebnis und die Messgenauigkeit.In the mop cover other contact surfaces can be integrated. The further contact surfaces are preferably electrically conductively operatively connected to the contact surfaces of the mop plate and thereby improve the measurement result and the measurement accuracy.

Der Wischbezug kann mit Metalldrähten oder elektrisch leitfähigen Fäden versehen sein. Diese sind vorzugsweise parallel zueinander angeordnet. Die Metalldrähte oder die Fäden verbessern ebenfalls das Messergebnis, da diese in einen definierten Abstand zueinander stehen und somit miteinander vergleichbare Messergebnisse liefern. Dazu sind die Metalldrähte vorzugsweise mit den weiteren Kontaktflächen verbunden. Es ist auch denkbar, dass die Metalldrähte in direktem Kontakt zu den Kontaktflächen der Wischplatte stehen oder dass die Metalldrähte oder die Fäden erweiterte Bereiche aufweisen, die weitere Kontaktflächen bilden. Metalldrähte oder Fäden sind besonders kostengünstig und einfach zu verarbeiten. Es ist aber auch denkbar, statt der Metalldrähte andere leitfähige Strukturen einzubinden. Derartige Strukturen können beispielsweise elektrisch leitfähige kohlenstoffhaltige Fäden sein.The mop cover may be provided with metal wires or electrically conductive threads. These are preferably arranged parallel to one another. The metal wires or threads also improve the measurement result, as they are at a defined distance from each other and thus provide comparable measurement results. For this purpose, the metal wires are preferably connected to the other contact surfaces. It is also conceivable that the metal wires are in direct contact with the contact surfaces of the mop plate or that the metal wires or the threads have extended areas that form further contact surfaces. Metal wires or filaments are particularly inexpensive and easy to work with. However, it is also conceivable to integrate other conductive structures instead of the metal wires. Such structures may be, for example, electrically conductive carbon-containing threads.

Die Messeinrichtung kann Nanotubes zur Erfassung von Wasserdampf umfassen. Nanotubes können je nach Ausrüstung flüchtige Gase detektieren, wobei erfindungsgemäß insbesondere Wasserdampf als Indikator für die Beladung des Wischbezugs mit Reinigungsflüssigkeit dient.The measuring device may comprise nanotubes for detecting water vapor. Depending on the equipment, nanotubes can detect volatile gases, in particular steam according to the invention serving as an indicator for the loading of the mop cover with cleaning liquid.

Bei dem erfindungsgemäßen Verfahren zur Überwachung der Reinigungsleistung eines an einer Wischplatte eines Wischgerätes befestigten Wischbezugs wird durch eine in die Wischplatte integrierte Messeinrichtung die in dem Wischbezug vorhandene Menge an Reinigungsflüssigkeit detektiert und ein Signal ausgelöst, wenn ein vorgebenener Schwellwert der Menge an Reinigungsflüssigkeit unter- oder überschritten wird. Das Anzeigen des Überschreitens einer Schwelle verhindert das Überladen des Wischbezugs mit Reinigungsflüssigkeit während des Ausspülens und nachfolgendem Auswringen, beziehungsweise beim Vorfeuchten oder Imprägnieren des Wischbezugs.In the method according to the invention for monitoring the cleaning performance of a mop cover attached to a mop plate of a mop, the amount of cleaning liquid present in the mop cover is detected by a measuring device integrated in the mop plate and a signal is triggered when a given threshold value undershoots or exceeds the amount of cleaning liquid becomes. The indication of exceeding a threshold prevents over-loading of the mop cover with cleaning liquid during rinsing and subsequent Wringing out, or when pre-moistening or impregnating the mop cover.

Ausführung der ErfindungEmbodiment of the invention

  • Figur 1 zeigt ein Wischgerät 1, hier ein Flachwischgerät, mit einer Wischplatte 2 an der gelenkig ein Stiel 11 befestigt ist. Auf der Wischplatte 2 ist ein Wischbezug 3 auswechselbar befestigbar. In die Wischplatte 2 ist eine Messeinrichtung 4 zur Detektierung der in dem Wischbezug 3 vorhandenen Restfeuchte integriert und die Messeinrichtung 4 ist mit einer Signaleinrichtung 5 wirkverbunden. Dabei ist die Messeinrichtung 4 fest in die Wischplatte 2 eingebunden und die optische und akustisch wirkende Signaleinrichtung 5 ist an der Oberseite, auf der dem Wischbezug 3 abgewandten Seite, der Wischplatte 2 befestigt. Die Messeinrichtung 4 weist zwei voneinander beabstandete Kontaktflächen 6, 7 auf, die auf der Unterseite, der dem Wischbezug 3 zugewandten Seite, der Wischplatte 2 angeordnet sind. Die Kontaktflächen 6, 7 sind mit dem Wischbezug 3 in Berührung bringbar. In dieser Ausgestaltung ist die Messeinrichtung 4 so ausgestaltet, dass sie den elektrischen Widerstand des Wischbezugs 3 bestimmt. Dazu werden die Kontaktflächen 6, 7 mit einer elektrischen Spannung beaufschlagt und durch die Messeinrichtung wird der elektrische Strom bestimmt. Der sich daraus ergebende elektrische Widerstand korreliert direkt mit der in dem Wischbezug 3 vorhandenen Restfeuchtigkeit und diese wiederum korreliert direkt mit der verbleibenden Reinigungsleistung des Wischbezugs 3 beziehungsweise der Beladung des Wischbezugs 3 mit Schmutz. Nach Überschreiten eines vorgebenen Schwellwertes des elektrischen Widerstandes, also nach Unterschreiten eines vorgegebenen Schwellwertes der Beladung mit Reinigungsflüssigkeit wird durch die Messeinrichtung 4 die Signaleinrichtung 5 ausgelöst. Dadurch wird der Reinigungskraft signalisiert entweder den Wischbezug 3 zu spülen oder auszutauschen. Zur Verbesserung des elektrischen leitenden Kontaktes sind in den Wischbezug 3 in dieser Ausgestaltung weitere Kontaktflächen 8, 9 integriert, die in Wirkverbindung mit den Kontaktflächen 6, 7 der Wischplatte 2 stehen. Zur Verbesserung und Vergleichmäßigung des Messergebnisses sind in den Wischbezug 3 ferner parallel zueinander angeordnete Metalldrähte 8, 9 integriert, die mit den Kontaktflächen 6, 7 der Wischplatte 2 während des Reinigens in Kontakt gebraucht werden. In einer anderen Ausgestaltung erfolgt die Messung des Leitwertes des Wischbezugs 3. Dabei wird der Wischbezug 3 mit einer Wechselspannung beaufschlagt und in Abhängigkeit des gemessenen elektrischen Stroms wird der Leitwert des Wischbezugs 3 bestimmt der wiederum in direktem Zusammenhang mit der noch vorhandenen Restfeuchte steht. Nach einem anderen erfindungsgemäßen Verfahren kann auch die Permittivität, also der Kapazitätswert des Wischbezugs 3 bestimmt werden. Die Permittivität des Werkstoffs des Wischbezugs 3, häufig ein Stoff basierend auf Polypropylen weicht sehr stark von der Permittivität von Wasser ab, so dass aus dem Wert der Permittivität der Gehalt an Restfeuchtigkeit bestimmt werden kann. Die Restfeuchtigkeit korreliert direkt mit der verbleibenden Reinigungsleistung des Wischbezugs 3 beziehungsweise der Beladung des Wischbezugs 3 mit Schmutz. Allen drei Verfahren ist gemeinsam, dass mittels eines elektrischen Kennwertes des Wischbezuges die Beladung des Wischbezugs 3 mit Reinigungsflüssigkeit detektiert werden kann. Dabei unterscheiden sich die jeweils erforderlichen Messeinrichtungen 4 nicht wesentlich voneinander, in allen Fällen wird der Wischbezug 3 mit einer elektrischen Spannung beaufschlagt und aus Beaufschlagung mit Spannung resultierende weitere elektrische Kenngrößen bestimmt. FIG. 1 shows a wiper device 1, here a flat mop, with a mop plate 2 on the articulated a handle 11 is attached. On the mop plate 2, a mop cover 3 is replaceable fastened. In the mop plate 2, a measuring device 4 for detecting the residual moisture present in the mop cover 3 is integrated and the measuring device 4 is operatively connected to a signaling device 5. In this case, the measuring device 4 is firmly integrated into the mop plate 2 and the optical and acoustically acting signal device 5 is fixed to the upper side, on the side facing away from the mop cover 3, the mop plate 2. The measuring device 4 has two spaced-apart contact surfaces 6, 7, which are arranged on the underside of the mop cover 3 facing side of the mop plate 2. The contact surfaces 6, 7 can be brought into contact with the mop cover 3. In this embodiment, the measuring device 4 is designed such that it determines the electrical resistance of the mop cover 3. For this purpose, the contact surfaces 6, 7 acted upon by an electrical voltage and by the measuring device, the electric current is determined. The resulting electrical resistance correlates directly with the existing in the mop cover 3 residual moisture and this in turn correlates directly with the remaining cleaning performance of the mop cover 3 and the loading of the mop cover 3 with dirt. After exceeding a predetermined threshold value of the electrical resistance, ie after falling below a predetermined threshold value of the load with cleaning liquid, the signal device 5 is triggered by the measuring device 4. As a result, the cleaning force is signaled either the mop cover 3 to flush or replace. To improve the electrical conductive contact, further contact surfaces 8, 9 are integrated into the mop cover 3 in this embodiment, which are in operative connection with the contact surfaces 6, 7 of the mop plate 2. In order to improve and even out the measurement result, metal wires 8, 9 arranged parallel to one another and integrated with the contact surfaces 6, 7 of the mop plate 2 during cleaning are integrated into the mop cover 3. In another embodiment, the measurement of the conductance of the mop cover 3. The mop cover 3 is supplied with an alternating voltage and depending on the measured electrical current, the conductance of the mop cover 3 is determined in turn is directly related to the residual moisture remaining. According to another method according to the invention, it is also possible to determine the permittivity, that is to say the capacitance value of the mop cover 3. The permittivity of the material of the mop cover 3, often a material based on polypropylene deviates very much from the permittivity of water, so that from the value of the permittivity of the content of residual moisture can be determined. The residual moisture correlates directly with the remaining cleaning performance of the mop cover 3 or the loading of the mop cover 3 with dirt. All three methods have in common that by means of an electrical characteristic value of the mop cover the loading of the Mop cover 3 can be detected with cleaning liquid. In this case, the respectively required measuring devices 4 are not significantly different from each other, in all cases, the mop cover 3 is subjected to an electrical voltage and determined from exposure to voltage resulting electrical characteristics.
