Um die Bearbeitungsrichtung zu ändern, ist gemäß der Erfindung vorgesehen, dass der am Motorgehäuse angebrachte Stiel verdrehbar ausgebildet ist. Um den Stiel an unterschiedliche Größen der Bearbeiter anzupassen, kann vorgesehen sein, dass der Stiel höhenverstellbar ausgebildet ist. Besonders bevorzugt ist es, wenn die jeweilige Höhe des Stieles, beispielsweise mit Hilfe einer Feststellschraube, in mehreren Stufen in der Höhe verstellt werden kann.The asymmetrical design of the care and cleaning device allows only one direction of machining on a wall. In order to change the machining direction, it is provided according to the invention that the handle mounted on the motor housing is rotatable. In order to adapt the stem to different sizes of the operator, it can be provided that the stem is designed to be height-adjustable. It is particularly preferred if the respective height of the stem, for example by means of a locking screw, can be adjusted in height in several stages.
Um eine ungefährliche Bedienung des erfindungsgemäßen Reinigungs- und Pflegegerätes zu gewährleisten, wenn der Stiel um 180° gedreht wird, ist vorgesehen, dass das handgeführte Reinigungs- und Pflegegerät eine Vorrichtung zur Änderung der Drehrichtung der Walzenbürste umfasst. Dies ist vorteilhaft, da die Drehrichtung der Walzenbürste bei normalem Betrieb so eingestellt ist, dass die resultierende Reibungskraft das Gerät vom Bediener wegzieht. Wird nun der Stiel um 180° gedreht, damit der Bediener in entgegengesetzter Richtung das Gerät führen kann, so zeigt, ohne eine Vorrichtung zur Änderung der Drehrichtung, die resultierende Reibungskraft in die entgegengesetzte Richtung, und das Gerät wird in Richtung des Bedieners gedrückt. Dies ist insbesondere deswegen gefährlich, da bei einem Widerstand des Bedieners die Bürstenwalze weiter nach unten gedrückt wird und somit die resultierende Reibungskraft gegen den Bediener weiter ansteigt. Um dies zu vermeiden, ist in einer fortgebildeten Ausführungsform der Erfindung vorgesehen, dass bei Verdrehen des Stiels um 180° aus Sicherheitsgründen eine automatische Drehrichtungsumkehr der Walzenbürste mit Hilfe der Vorrichtung zur Änderung der Drehrichtung erfolgt. Hierzu gibt es mehrere Möglichkeiten. In einer ersten Ausgestaltung ist vorgesehen, dass die Vorrichtung zur Änderung der Drehrichtung wenigstens zwei bei Verdrehung des Stiels auslösbare elektrische Schalter umfasst. Die Auslösung der Schalter kann mit Hilfe einer am Stiel angeordneten Schaltwelle erfolgen, wobei die Schaltwelle bevorzugt Schaltnocken zur Betätigung der wenigstens zwei Schalter umfasst. Um die Richtungsumkehr bei einem Einphasen-Reihenschlussmotor, der bevorzugt im vorliegenden Reinigungs- und Pflegegerät Verwendung findet, zu ermöglichen, ist vorgesehen, dass in Reihe angeordnete Leitungen der Statorwicklung und der Bürsten entkoppelt werden. Die vier Leitungen können dann mit den Schaltern verbunden werden und über die Schalter jeweils angesteuert werden. Durch eine derartige Ausgestaltung ist sichergestellt, dass bei einem eingeschalteten Handschalter am Griff des Stieles des Reinigungs- und Pflegegerätes der Elektromotor nur in den jeweiligen Endstellungen des Stieles, d.h. in der ersten und zweiten Position, der Motor spannungsgeführt ist. Ist der Stiel in einer Zwischenstellung, so sind die Schalter nicht geschaltet und der Motor ist spannungsfrei.In order to ensure a safe operation of the cleaning and care device according to the invention, when the handle is rotated by 180 °, it is provided that the hand-held cleaning and care device comprises a device for changing the direction of rotation of the roller brush. This is advantageous because the direction of rotation of the roller brush during normal operation is set so that the resulting frictional force pulls the device away from the operator. Now, if the stem is rotated by 180 °, so that the operator can lead the device in the opposite direction, so shows, without a device for changing the direction of rotation, the resulting friction force in the opposite direction, and the device is pressed in the direction of the operator. This is particularly dangerous because, with resistance of the operator, the brush roller is pushed further down and thus the resulting frictional force against the operator continues to increase. In order to avoid this, it is provided in a developed embodiment of the invention that upon rotation of the handle by 180 °, for safety reasons, an automatic reversal of rotation of the roller brush with the aid of the device for changing the direction of rotation. There are several possibilities for this. In a first embodiment, it is provided that the device for changing the direction of rotation comprises at least two electrical switches which can be triggered upon rotation of the handle. The triggering of the switch can be done with the aid of a stem arranged on the switching shaft, wherein the switching shaft preferably comprises switching cam for actuating the at least two switches. In order to enable the direction reversal in a single-phase series motor, which is preferably used in the present cleaning and care device, it is provided that lines arranged in series of the stator winding and the brushes are decoupled. The four lines can then be connected to the switches and be controlled via the switch respectively. Such an embodiment ensures that when the handset is switched on the handle of the handle of the cleaning and care device, the electric motor is energized only in the respective end positions of the stem, ie in the first and second positions. If the stem is in an intermediate position, the switches are not switched and the motor is de-energized.
Alternativ ist eine mechanische Umschaltung denkbar oder eine Ansteuerung der Motorregelung zur Drehrichtungsumkehr.Alternatively, a mechanical changeover is conceivable or a control of the motor control to reverse the direction of rotation.
