Description
Die Erfindung bezieht sich auf einen Rotor für eine Vorrichtung zum Reinigen von Teppichen und Polstermöbelstoffen gemäß US-A-4 095 303 nach dem Oberbegriff des Anspruches 1. Es ist bekannt, Textilien wie Teppiche und Polstermöbelstoffe unter Verwendung von Shampoonaten, Schäumen oder nach RAL 991 A2 zu reinigen. Es ist auch bekannt, Teppichböden nach vorherigem Behandeln mit einem chemischen Wirkstoff mittels Teppichreinigungsmaschinen mit rotierenden Bürsten zu reinigen, die die Schmutzpartikel mechanisch von den Fasern der Teppichböden lösen. Diese Methode hat jedoch den Nachteil, daß die behandelten Teppichböden bis zu ihrer völligen Trocknung u.U. bis zu mehreren Tagen nicht betreten werden können.The invention relates to a rotor for a device for cleaning carpets and upholstery materials according to US-A-4 095 303 according to the preamble of claim 1. It is known to use textiles such as carpets and upholstery fabrics using shampooates, foams or according to RAL 991 A2 to clean. It is also known to clean carpets after prior treatment with a chemical agent using carpet cleaning machines with rotating brushes which mechanically loosen the dirt particles from the fibers of the carpets. However, this method has the disadvantage that the treated carpets may dry until they are completely dry. cannot be entered for up to several days.
Durch US-A-4 186 030 und 4 067 082 ist es auch schon bekannt geworden, Teppiche und Teppichböden unter Zuhilfenahme geeigneter Reinigungschemikalien mittels elektrostatischer Kraft zu reinigen. Hierbei ist ein fahrbares Gestell vorgesehen, das einen Elektromotor vorsieht, der mit einem Rotor mit einer Isoliermaterial-Scheibe verbindbar ist, an dessen Unterseite eine Reinigungsmatte aus Polgewebe oder dergleichen angebracht werden kann. Durch die Rotation der Reinigungsmatte auf dem Teppichboden wird dabei durch Reibung ein elektrostatisches Feld erzeugt. Die Ausbildung und Anordnung ist dabei so getroffen, daß der Rotor mit der Reinigungsmatte einerseits und der mit einer geeigneten Reinigungschemikalie eingesprühte Teppichboden andererseits ungleichnamig aufgeladen werden, wodurch die Schmutzpartikel sich aus dem Teppichboden lösen und aufgrund der wirksamen elektrostatischen Kräfte sich auf der am Rotor angebrachten Reinigungsmatte ablagern.From US-A-4 186 030 and 4 067 082 it has also become known to clean carpets and carpets with the aid of suitable cleaning chemicals by means of electrostatic force. Here, a mobile frame is provided, which provides an electric motor that can be connected to a rotor with an insulating material disc, on the underside of which a cleaning mat made of pile fabric or the like can be attached. The rotation of the cleaning mat on the carpet creates an electrostatic field due to friction. The design and arrangement is such that the rotor with the cleaning mat on the one hand and the Carpet sprayed with a suitable cleaning chemical, on the other hand, is charged unevenly, whereby the dirt particles come loose from the carpet and are deposited on the cleaning mat attached to the rotor due to the effective electrostatic forces.
Nach dem gleichen Prinzip arbeitet auch die Vorrichtung nach US-A-4 095 303, deren Rotor aus einer oberen ringförmigen Kupplungsscheibe für den Antrieb und einer unteren Mitnahmescheibe für ein Reinigungskissen aufgebaut ist, die über kreisscheibenförmiges Isoliermaterial miteinander verklebt sind. Das Isoliermaterial ist aus abwechselnd aufeinanderfolgenden, glattflächigen Scheiben aus Plexiglas (Warenzeichen) und Metallfolie aufgebaut, die miteinander verklebt sind.The device according to US-A-4 095 303 works according to the same principle, the rotor of which is made up of an upper annular clutch disk for the drive and a lower drive disk for a cleaning pad, which are glued together by circular disk-shaped insulating material. The insulating material is made up of alternating successive, smooth-surface panes made of plexiglass (trademark) and metal foil, which are glued together.
Diese bekannten Vorrichtungen haben den Vorteil, daß durch Ausnutzung thermoelektrischer Effekte mit weniger Reinigungschemikalien eine schonendere Behandlung und schnellere Trocknung der Teppichböden erzielt wird, als mit nur mechanisch wirksamen Maschinen.These known devices have the advantage that more gentle treatment and faster drying of the carpets is achieved by using thermoelectric effects with fewer cleaning chemicals than with only mechanically effective machines.
Der Erfindung liegt die Aufgabe zugrunde, die Vorrichtung gemäß US-A-4 095 303 zu optimieren, um durch Verstärkung des thermoelektrischen Effektes eine verbesserte Reinigungswirkung zu erzielen.The invention has for its object to optimize the device according to US-A-4 095 303 in order to achieve an improved cleaning effect by enhancing the thermoelectric effect.
Diese Aufgabe wird durch die Merkmale des Kennzeichens des Anspruches 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.
Durch die zwischen den einzelnen Scheiben des Rotors gebildeten Luftpolster wird erreicht, daß die durch die Reibung des Reinigungskissens auf dem Textil erzeugte und auf den Rotor übergehende Wärme in diesem vermehrt gespeichert wird, so daß das zwischen Rotor und Textil bestehende Temperaturgefälle, das analog dem bekannten sogannten Seebeck-Effekt in Verbindung mit den vorhandenen elektrostatischen Kräften ein Herauslösen der Schmutzpartikel aus dem zuvor mit einer geeigneten Reinigungschemikalie behandelten Textil sowie deren Beförderung zum und Festhalten im Reinigungskissen bewirkt, erhöht wird. Von Vorteil ist dabei auch, daß beim üblichen Wechsel des mit Schmutzpartikeln gesättigten Reinigungskissens gegen ein frisches Reinigungskissen, dieses durch die im Rotor gespeicherte Wärme schon beim Aufbringen auf den Rotor erwärmt wird. Das Temperaturgefälle zwischen Rotor bzw. Reinigungskissen einerseits und Textil andererseits und damit der vorteilhafte thermoelektrische Effekt bleibt daher während der gesamten Behandlungsdauer im wesentlichen unverändert erhalten.The air cushions formed between the individual disks of the rotor ensure that the heat generated by the friction of the cleaning pad on the textile and transferred to the rotor is increasingly stored in it, so that the temperature gradient existing between the rotor and textile, which is analogous to the known one so-called Seebeck effect in connection with the existing electrostatic forces Removing the dirt particles from the textile previously treated with a suitable cleaning chemical and transporting them to and holding them in the cleaning cushion is increased. It is also advantageous that, when the cleaning pad saturated with dirt particles is exchanged for a fresh cleaning pad, it is heated by the heat stored in the rotor when it is applied to the rotor. The temperature gradient between the rotor or cleaning pad on the one hand and the textile on the other hand and therefore the advantageous thermoelectric effect is therefore essentially unchanged throughout the treatment period.
Vorteilhafte weitere Ausgestaltungen der Erfindung. sind in den Unteransprüchen definiert.Advantageous further developments of the invention. are defined in the subclaims.
Die Erfindung ist in der Zeichnung in einem Ausführungsbeispiel schematisch dargestellt und wird anhand dieser im folgenden erläutert. Es zeigenThe invention is shown schematically in the drawing in an exemplary embodiment and is explained below with reference to this. Show it
Figur 1 einen Schnitt gemäß der Linie A-A der Figur 2 und
Figur 2 eine Draufsicht auf die Unterseite eines erfindungsgemäßen Rotors.1 shows a section along the line AA of Figure 2 and
Figure 2 is a plan view of the underside of a rotor according to the invention.
Gemäß der Zeichnung weist die unterste, dem Reinigungskissen 2 benachbarte, Scheibe 3 des Rotors 1 vollen Kreisquerschnitt auf. Auf der Scheibe 3 sind die Ringscheiben 4 angeordnet, von denen die oberste mit den Vorsprüngen 5 versehen ist. Diese Vorsprünge 5, vorzugsweise drei gleichmäßig über den Umfang verteilt angeordnet, dienen zur lösbaren Verbindung, beispielsweise nach Art eines Bajonettverschlusses, mit dem nicht gezeigten Antrieb. Abgesehen von den Vorsprüngen 5 der obersten Scheibe haben alle Scheiben 4 den gleichen Innen- und Außendurchmesser. Die Scheiben 4 sind miteinander und die unterste Scheibe 4 ist mit der Scheibe 3 längs ihres äußeren und inneren Randes auf einer Breite von beispielsweise etwa 1 cm rundum dicht verklebt, beispielsweise mittels eines organischen Lösungsmittelklebers. Die einander benachbarten Flächen aller Scheiben sollen im übrigen jedoch in nicht gezeigter Weise mit einer mehr oder weniger großen Aufrauhung versehen sein, so daß sich zwischen je zwei einander benachbarten Scheiben ein völlig abgeschlossenes Luftpolster befindet.According to the drawing, the
An der Unterseite der Scheibe 3 sind die drei über den Umfang gleichmäßig verteilt angeordneten Beborstungen 6 vorgesehen. Zweckmäßig sind die verhältnismäßig harten Borsten in einem geeigneten Trägermaterial verankert und mittels dieses in entsprechenden Vertiefungen der Scheibe 3 angebracht, beispielsweise eingeklebt. Die überstehende Länge der Borsten wird dabei so gewählt, daß ein sicheres Mitnehmen des Reinigungskissens 2 immer gewährleistet ist, gleichgültig, ob es sich bei diesem um ein einseitig oder beidseitig verwendbares Reinigungskissen handelt.The three bristles 6 arranged uniformly distributed over the circumference are provided on the underside of the
Damit eine Verfilzung des Kissens, wie sie im Drehpunkt und dem diesen umgebenden nahen Bereich auftreten und zu einer Beschädigung des Textils, bei dem es sich bei der Behandlung mit der erfindungsgemäßen Vorrichtung sowohl um Wollmaterialien wie auch synthetische Materialien handeln kann, führen könnte, sicher vermieden wird, kann es sich als zweckmäßig erweisen, ein Reinigungskissen mit einer zentralen Aussparung zu verwenden. In diesem Fall kann die Scheibe 3 ebenfalls eine zentrale Öffnung entsprechenden oder auch etwas geringeren Durchmessers aufweisen.This reliably prevents matting of the pillow, such as occurs in the pivot point and the surrounding area surrounding it, and damage to the textile, which could result in both wool materials and synthetic materials being treated with the device according to the invention it may prove useful prove to use a cleaning pad with a central recess. In this case, the
Abweichend von den in der Zeichnung gezeigten Abmessungen können das Reinigungskissen 2, die Scheibe 3 und die Scheiben 4 auch gleichen Durchmesser aufweisen. Ebenso kann anstelle der Vorsprünge 5 selbstverständlich auch eine andere Verriegelung zwischen Rotor 1 und Antrieb vorgesehen werden. Desgleichen sind Anordnung, Form und Abmessungen der Beborstungen 6 nur als beispielhafte Angaben zu verstehen und können selbstverständlich auch davon abweichen.Deviating from the dimensions shown in the drawing, the cleaning pad 2, the
Die Scheiben 3 und 4, die zweckmäßig eine Dicke von etwa 2 bis 6, vorzugsweise 3 bis 5 mm, aufweisen, brauchen selbstverständlich nicht alle die gleiche Dicke aufweisen, vielmehr können auch Scheiben unterschiedlicher Dicke miteinander gepaart werden.The
Es versteht sich, daß der sich bei der Behandlung von Teppich, Teppichböden oder Polstermöbelstoffen einstellende thermoelektrische und elektrostatische Effekt von einer Reihe von Faktoren beeinflusst wird. Entsprechend wird der Aufbau des Rotors 1 hinsichtlich des Materials sowie der Zahl und Dicke der verwendeten Scheiben, der Größe der Luftpolster, zu dessen Erzielung eine Aufrauhung von wenigen 1/10 mm Tiefe genügt, der Größe des inneren und äußeren Durchmessers und in Verbindung mit diesem die jeweilige Drehzahl des Rotors 1 bzw. des auf diesem angeordneten Reinigungskissens in Abstimmung mit dem zu behandelten Produkt sowie der Art und Menge der dabei verwendeten Reinigungschemikalie gewählt.It is understood that the thermoelectric and electrostatic effect which arises in the treatment of carpet, carpets or upholstered furniture materials is influenced by a number of factors. Accordingly, the structure of the rotor 1 with respect to the material and the number and thickness of the discs used, the size of the air cushion, to achieve a roughening of a few 1/10 mm depth is sufficient, the size of the inner and outer diameter and in connection with this the respective speed of rotation of the rotor 1 or of the cleaning pad arranged thereon in coordination with the one to be treated Product and the type and amount of cleaning chemicals used.
Aufgrund dessen, daß die in einer Menge von beispielsweise etwa 5 bis etwa 100 ml/m² auf ein Textil aufgesprühte, beispielsweise organische Tenside, Alkohole, waschaktive Substanzen und wässrige Lösungen enthaltende und einen pH-Wert von vorzugsweise etwa 6,2 bis 7,5 aufweisende Reinigungschemikalie durch die Reibungswärme einer schnellen Verdunstung ausgesetzt ist, ist es von Fall zu Fall möglich, in einer Zeit von etwa 20 min bis zu etwa 2 h eine volle Trocknung des Textils zu erreichen, ohne an den Fasern des Textils Seifensubstanzen zu hinterlassen, die ein schnelles Wiederanschmutzen der Fasern zur Folge hätten. Es hat sich im Gegenteil gezeigt, daß ein Ergebnis erzielt wird, bei dem die behandelten Fasern nicht schneller wieder anschmutzen als das Anschmutzen bei einer Neuware der Fall ist.Because of the fact that the sprayed onto a textile in an amount of, for example, about 5 to about 100 ml / m 2, which contains, for example, organic surfactants, alcohols, detergent substances and aqueous solutions, and a pH value of preferably about 6.2 to 7.5 cleaning chemical exposed to rapid evaporation due to the frictional heat, it is possible from case to case to achieve full drying of the textile in a time from approximately 20 minutes to approximately 2 hours, without leaving soap substances on the fibers of the textile, which rapid re-soiling of the fibers would result. On the contrary, it has been shown that a result is achieved in which the treated fibers do not become soiled again faster than soiling is the case with new goods.
