Abstract

Method and plant for cleaning textile products, particularly carpets by means of a textile cleaning apparatus, the surface to be cleaned being treated with a cleaning liquid. Problems occur with known methods and plants which involve a cleaning by means of powder, a shampoo and a removal by spraying, and also particularly those which use an electrostatic charge. The problems occur mainly because the fabric is not cleaned sufficiently rapidly nor thoroughly in depth. The present invention solves those problems by effecting a cleaning at a high temperature, a heating surface (37) approximately parallel to the surface to be cleaned (19) rotating in efficient relationship on the cleaning surface. The temperature of the heating surface is regulated according to the type of textile, the cleaning product, the soiled state and the ambient conditions, preferably in a range of 110-170oC.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Reinigung von Textilien, insbesondere von Teppichen mittels eines Textilreinigungsgerätes, mit einem von einer Antriebsvorrichtung mit einer Nenndrehzahl von 120 bis 240 Umdrehungen pro Minute angetriebenen Rotor, sowie mit einer aus einer mitdrehenden Reinigungsmatte bestehenden Reinigungsfläche, wobei die zu reinigende Fläche mit einer Reinigungsflüssigkeit behandelt wird.The invention relates to a method and a device for cleaning textiles, in particular carpets by means of a textile cleaning device, with a rotor driven by a drive device with a nominal speed of 120 to 240 revolutions per minute, and with a cleaning surface consisting of a rotating cleaning mat, the surface to be cleaned is treated with a cleaning liquid.

Aus der DE-U-8 304 300.7 ist eine Teppichreinigungsvorrichtung der genannten Art bekannt, die sich die elektrostatische Aufladung der Schmutzpartikel zunutze machen will. Durch den relativ langsam zwischen 120 und 240 Umdrehungen pro Minute drehenden Rotor wird eine Beschädigung des zu reinigenden Teppichs vermieden, der Reinigungserfolg ist aber beschränkt. Eine Reinigung unter erhöhter Temperatur ist hiernach nicht vorgesehen.From DE-U-8 304 300.7 a carpet cleaning device of the type mentioned is known, which wants to take advantage of the electrostatic charge of the dirt particles. Damage to the carpet to be cleaned is avoided by the rotor, which rotates relatively slowly between 120 and 240 revolutions per minute, but the cleaning success is limited. Cleaning at elevated temperatures is not intended after this.

In der DE-A-2 615 501 wird als Teppichreiniger ein Sprühextraktionsgerät beschrieben. Bei diesem Waschsauger - Druckluft-Sprüh-und Saugsystem, zur Feuchtreinigung von fest verlegten Stoffen, Polstermöbeln und Teppichböden mittels eines Dreidüsen-Systems, wird Reinigungsflüssigkeit von einem Behälter durch ein Rohr über eine Flachstrahldüse mittels Druckluft, die von einer elektrischen Heizung erhitzt werden kann, auf den zu reinigenden Stoff gepresst und durch zwangsgeführtes Absaugen von zwei Saugdüsen sofort wieder abgezogen, und mit durch zwangsgeführte Heissluft wird der Stoff getrocknet. Ein derartiges System ist konstruktiv sehr aufwendig und bezüglich der Anwendung sehr kompliziert. Ausserdem werden grosse Mengen an Reinigungsmitteln benötigt und die Abtrocknungszeit ist trotz Heizung noch verhältnismässig lang. Im Teppich können darüberhinaus Verspannungen bzw. Formänderungen auftreten.DE-A-2 615 501 describes a spray extraction device as a carpet cleaner. With this vacuum cleaner - compressed air spray and suction system, for wet cleaning of permanently installed materials, upholstered furniture and carpets using a three-nozzle system, cleaning liquid is fed from a container through a pipe via a flat jet nozzle using compressed air, which can be heated by an electric heater. pressed onto the material to be cleaned and immediately pulled off by forced suction of two suction nozzles, and the material is dried with forced air. Such a system is structurally very complex and very complicated to use. In addition, large amounts of cleaning agents are required and the drying time is still relatively long despite heating. In addition, tension or changes in shape can occur in the carpet.

Die vorliegende Erfindung stellt sich die Aufgabe, ein Verfahren und eine Vorrichtung neuer Art zur Reinigung von Textilien vorzustellen, insbesondere zur Reinigung von Teppichen, wobei die Reinigung mit verhältnismässig geringem Aufwand an Reinigungsflüssigkeit erfolgen soll und bis in die Tiefe des Gewebes gereinigt wird und wobei selbst bei empfindlichen Velours keine Oberflächenveränderung des Flors erfolgt. Zudem sollen möglichst keine Rückstände der waschaktiven Substanzen im Teppichboden verbleiben, wodurch die frühzeitige Wiederverschmutzung vermieden werden kann. Das neue Reinigungsgerät soll ferner besonders einfach zu bedienen, betriebssicher und wartungsfreundlich sein sowie eine schnelle Reinigung gewährleisten.The object of the present invention is to present a method and a device of a new type for cleaning textiles, in particular for cleaning carpets, the cleaning being to be carried out with relatively little expenditure of cleaning liquid and being cleaned to the depth of the fabric, and being itself there is no change in the surface of the pile in the case of sensitive velor. In addition, as far as possible, no residues of the washing-active substances should remain in the carpeting, as a result of which early re-contamination can be avoided. The new cleaning device should also be particularly easy to use, reliable and easy to maintain and guarantee quick cleaning.

Die Lösung der gestellten Aufgabe gelingt für das Verfahren erfindungsgemäss dadurch, dass die Reinigung unter einer erhöhten Temperatur erfolgt, wobei eine zur reinigenden Fläche in etwa parallele Heizfläche in Wirkungsverbindung über der zu reinigenden Fläche rotiert und die Temperatur der zu reinigenden Fläche zwischen 40 und 80 Grad Celsius liegt. Aufgrund der gegenüber der Umgebungs- oder Raumtemperatur erhöhten Temperatur wird der Reinigungsvorgang kontinuierlich und kontrollierbar aktiviert. Auf diese Weise kann ein optimaler Reinigungserfolg gezielt eingestellt werden, wobei die Reinigung besonders schnell und gründlich erfolgt. Bei gleichem Zeitaufwand können grössere Flächen gereinigt werden, wobei gleichzeitig die Trocknungszeit der Textilien verkürzt wird.According to the invention, the object is achieved in that the cleaning takes place at an elevated temperature, a heating surface approximately parallel to the cleaning surface rotating in operative connection over the surface to be cleaned and the temperature of the surface to be cleaned between 40 and 80 degrees Celsius is. Due to the higher temperature than the ambient or room temperature, the cleaning process is activated continuously and controllably. In this way, optimal cleaning success can be set in a targeted manner, with cleaning being particularly quick and thorough. Larger areas can be cleaned at the same time, while the drying time of the textiles is reduced.

In vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, dass die Temperatur der Heizfläche in Abhängigkeit von der Textilart, dem Reinigungsmittel, dem Verschmutzungsgrad und den Umgebungsbedingungen konstant geregelt wird. Auf diese Weise kann die optimale Reinigungstemperatur leicht eingestellt und kontinuierlich eingehalten werden.In an advantageous embodiment of the invention, it is provided that the temperature of the heating surface is constantly controlled as a function of the type of textile, the cleaning agent, the degree of soiling and the ambient conditions. In this way, the optimal cleaning temperature can be easily set and maintained continuously.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Temperatur der Heizfläche bei der Reinigung von Teppichen in einem Bereich zwischen 100 bis 250 Grad Celsius, vorzugsweise zwischen 110 und 170 Grad Celsius eingestellt wird. Durch Versuche wurde überraschend festgestellt, dass in diesem Temperaturbereich die meisten gängigen Teppicharten, gewebte Teppichböden mit Juterücken, selbst verspannte Teppichböden etc. erfindungsgemäss gereinigt werden können, wobei sich Temperaturen an der zu reinigenden Teppichfläche zwischen etwa 40 und 80 Grad Celsius einstellen können.In a further embodiment of the invention it is provided that the temperature of the heating surface when cleaning carpets is set in a range between 100 to 250 degrees Celsius, preferably between 110 and 170 degrees Celsius. Experiments have surprisingly found that in this temperature range, most common types of carpets, woven carpets with jute backs, even tensioned carpets, etc. can be cleaned according to the invention, with temperatures on the carpet surface to be cleaned being able to be between about 40 and 80 degrees Celsius.

Bei der Vorrichtung zur Durchführung des erfindungsgemässen Verfahrens mit einem von einer Antriebseinrichtung angetriebenen Rotor und einer an der Unterseite des Rotors angeordneten Antriebsplatte sowie einer Reinigungsmatte, besteht die Lösung der gestellten Aufgabe darin, dass die Antriebsplatte eine Heizeinrichtung aufweist. Hiermit wird eine allgemeine, aberfür den Fachmann eindeutige Lehre zum technischen Handeln zur Verwirklichung des Verfahrens nach der Erfindung aufgezeigt.In the device for carrying out the method according to the invention with a rotor driven by a drive device and a drive plate arranged on the underside of the rotor and a cleaning mat, the solution to the problem is that the drive plate has a heating device. This shows a general teaching, which is clear to a person skilled in the art, on technical action for realizing the method according to the invention.

Ferner ist mit der Erfindung vorgesehen, dass die Heizeinrichtung als Metallscheibe mit spiralförmig angeordneten Rillen zur Aufnahme von Heizdrähten oder Heizwicklungen ausgebildet ist. Bei dieser Massnahme handeltes sich um eine besonders einfache und robuste Ausführungsform einer Heizung. Dasgleiche gilt für eine kreisringförmige Anordnung der Rillen, die einen Heizdraht aufnehmen, der an der Querverbindung der Rillen zueinander jeweils in die benachbarte Rille geführt ist.The invention further provides that the heating device is designed as a metal disk with spirally arranged grooves for receiving heating wires or heating windings. This measure is a particularly simple and robust embodiment of a heater. The same applies to an annular arrangement of the grooves which receive a heating wire which is guided in the adjacent groove at the transverse connection of the grooves to one another.

Besonders zweckmässig ist es, wenn die Heizeinrichtung mit einem oder mehreren Regulatoren verbunden ist, die vorzugsweise auf der Rotorhaube und/oder am Handgriff des Reinigungsgerätes angeordnet sind. Beispielsweise kann zur Verbesserung des Bedienungskomforts der Regulator an der Rotorhaube zur Grobeinstellung und der andere Regulator am Handgriff zur Feineinstellung der Temperatur verwendet werden. Aus Kostengründen kann aber auch nur ein Regulator wahlweise an der Rotorhaube oder am Handgriff angebracht sein. Auch ist es denkbar, den Regulataor mi't Temperaturanzeige an der Motorhaube anzuordnen.It is particularly expedient if the heating device is connected to one or more regulators, which are preferably arranged on the rotor hood and / or on the handle of the cleaning device. For example, the regulator on the rotor hood for rough adjustment and the other regulator on the handle for fine adjustment of the temperature can be used to improve the ease of use. For cost reasons, however, only one regulator can be attached either to the rotor hood or to the handle. It is also conceivable to arrange the regulator with temperature display on the bonnet.

Vorteilhaft wird die Erfindung dadurch ausgestaltet, dass der Rotor zwischen der Heizeinrichtung und dem Rotorblock eine vorzugsweise aus einer hoch hitzebeständigen Schutzschicht, beispielsweise aus Glas- oder Mineralfaser bestehende Isolationsschicht aufweist. Ein aus niedrig schmelzendem Kunststoff aus Isoliermaterial bestehender Rotorblock wird so gegen thermische Belastung und Beschädigung geschützt.The invention is advantageously designed in such a way that the rotor between the heating device and the rotor block has an insulation layer which preferably consists of a highly heat-resistant protective layer, for example made of glass or mineral fiber. One made of low melting Plastic rotor block made of insulating material is thus protected against thermal stress and damage.

Eine weitere Ausgestaltung der Erfindung sieht vor, dass zwischen Rotorblock und Heizeinrichtung eine Reflektionsscheibe angeordnet ist. Zum einen wird dadurch der Rotorblock besonders gut geschützt, zum anderen bewirkt diese Massnahme eine Minimierung der Energieverluste und damit eine Erhöhung der Wirtschaftlichkeit.A further embodiment of the invention provides that a reflection disk is arranged between the rotor block and the heating device. On the one hand, this protects the rotor block particularly well, and on the other hand, this measure minimizes energy losses and thus increases efficiency.

In weiteren Ausgestaltungen der Erfindung ist vorgesehen, dass die Antriebs- und Heizplatte eine Riffelung aufweist, vorzugsweise gebildet durch senkrecht gegeneinander gefräste v-förmige Rillen. Hierdurch kann auf einfache Weise eine ausreichende Haftung zwischen Antriebsplatte und Reinigungsmatte im Betriebszustand erzielt werden.In further refinements of the invention, it is provided that the drive and heating plate has a corrugation, preferably formed by v-shaped grooves milled perpendicular to one another. Sufficient adhesion between drive plate and cleaning mat in the operating state can thereby be achieved in a simple manner.

Below the heating device 37 is the drive plate 39, which forms the actual heating surface in relation to the carpet surface to be cleaned and by means of connecting elements such as e.g. Screws 40, rigidly connected to the rotor block 30 or the drive plate 39. Heating device 37 and drive plate 39 can advantageously also be formed in one piece (not shown). The drive plate 39, which is firmly connected to the heating plate 37 and has an outer diameter of approximately 30 to 40 cm, can be made, for example, of aluminum or other metals or metal alloys, coated or uncoated to improve heat transfer, and has a plurality of elevations, nipples or grooves on its underside , which are in engagement with a preferably waffle-shaped back surface of the replaceable cleaning mat 20. The positive engagement resulting from the engagement in connection with the frictional engagement caused by the weight of the carpet cleaning machine enables the cleaning mat 20 to rotate together with the rotor 17.

Nach dem erfindungsgemässen Reinigungsverfahren wird die zu reinigende Teppichfläche mit einer speziellen Reinigungsflüssigkeit besprüht, die neben Wasser einige waschaktive Substanzen sowie verschiedene Alkohole enthält. Zur Aktivierung des Reinigungsvorganges wird danach die Reinigungsvorrichtung mit ihrem in vertikaler Rotationsachse drehender Rotor 17 eingesetzt, wobei die Umdrehungsgeschwindigkeit des Rotors im Bereich zwischen 120 bis 240 Umdrehungen pro Minute liegt. Unter der Maschine, unmittelbar auf der zu reinigenden Teppichoberfläche 19, liegt die Reinigungsmatte 20, die vor ihrer Verwendung ebenfalls mit der vorgenannten Reinigungsflüssigkeit getränkt wurde. Durch die Bewegung des Rotors 17 in Verbindung mit der durch die Heizung 37 am Regulator 18 bzw. 21 eingestellten optimalen Reinigungstemperatur im Bereich der die Heizfläche bildenden Antriebsplatte 39 werden die Schmutzpartikel mittels der Reinigungslösung in die Reinigungsmatte 20 überführt und sammeln sich dort an. Je nach Verschmutzungsgrad des Teppichs wird die Reinigungsmatte 20 für einen zweiten oder auch dritten Reinigungsvorgang gewechselt. Später werden die verschmutzten Reinigungsmatten 20 in normalen Haushaltswaschmaschinen gewaschen oder je nach Verschmutzungsgrad einfach nur ausgewrungen und wieder verwendet.According to the cleaning method according to the invention, the carpet surface to be cleaned is sprayed with a special cleaning liquid which, in addition to water, contains some washing-active substances and various alcohols. To activate the cleaning process, the cleaning device with its rotor 17 rotating in the vertical axis of rotation is then used, the rotational speed of the rotor being in the range between 120 to 240 revolutions per minute. Under the machine, directly on the carpet surface 19 to be cleaned, lies the cleaning mat 20, which was also soaked with the aforementioned cleaning liquid before it was used. Due to the movement of the rotor 17 in connection with the optimal cleaning temperature set by the heater 37 on the regulator 18 or 21 in the area of the drive plate 39 forming the heating surface, the dirt particles are transferred into the cleaning mat 20 by means of the cleaning solution and collect there. Depending on the degree of soiling of the carpet, the cleaning mat 20 is changed for a second or third cleaning process. The soiled cleaning mats 20 are later washed in normal household washing machines or, depending on the degree of soiling, are simply wrung out and used again.

Die erfindungsgemässen Massnahmen sind jedoch nicht auf das in den Zeichnungsfiguren dargestellte Ausführungsbeispiel beschränkt. Beispielsweise können auch mehrere Rotoren mit vertikalen Rotoationsachsen verwendet werden, beziehungsweise alle geeigneten konventionellen Teppichreinigungsgeräte, sofern diese mit der erfindungsgemässen Heizeinrichtung ausgestattet werden können.However, the measures according to the invention are not limited to the exemplary embodiment shown in the drawing figures. For example, several rotors with vertical rotation axes can also be used, or all suitable conventional carpet cleaning devices, provided that these can be equipped with the heating device according to the invention.

Auch die Art der Heizeinrichtung ist nicht auf das Ausführungsbeispiel beschränkt. Daneben sind andere, zum Stand der Technik gehörende Varianten ebenfalls verwendbar, sofern diese geeignet sind, die Aufgabe nach der Erfindung zu lösen.The type of heating device is also not limited to the exemplary embodiment. Next to it are on their variants belonging to the prior art can also be used, provided they are suitable for achieving the object of the invention.
