Abstract
Die Vorrichtung dient dem Saugen von Blättern und Blüten in Gärten und Parks. Sie besteht im wesentlichen aus einem gebogenen Rohr, in das ein Elektromotor eingebaut ist, der einen Propeller antreibt, desssen Kanten als scharfe Klingen ausgeführt sind. Das Sauggut wird so in einen Fangsack befördert. Die Vorrichtung kann für den Handbetrieb mit Rädern und einer Führungsstange versehen werden. Es ist auch möglich, die Vorrichtung mit einem Antrieb zu versehen, so dass sie ähnlich einem Mähroboter selbstständig ein Areal abfahren kann. Die Vorrichtung kann mit einem Mähroboter kombiniert werden. Dazu sind die beiden Teile Mähroboter und Laubsauger in einem gemeinsamen Gehäuse untergebracht und werden von einem gemeinsamen Akku betrieben. Dazu kommen Farbsensoren, die den Motor des Blattsaugers, bei Bedarf einschalten. So reduziert sich der ohnehin niedrige Energieverbrauch. Da das gesamte Aggregat regelmäßig im Einsatz ist, fällt in einem Durchgang auch wenig Laub an, so dass der Fangsack nur selten geleert werden muss. The device is used for sucking leaves and flowers in gardens and parks. It consists essentially of a curved tube, in which an electric motor is installed, which drives a propeller whose edges are designed as sharp blades. The suction material is transported in a collecting bag. The device can be provided for manual operation with wheels and a guide rod. It is also possible to provide the device with a drive, so that it can independently start an area similar to a robotic lawnmower. The device can be combined with a robotic lawnmower. For this purpose, the two parts robotic lawnmower and leaf vacuum cleaner are housed in a common housing and are operated by a common battery. There are also color sensors that turn on the motor of the leaf vacuum, if necessary. This reduces the already low energy consumption. Since the entire unit is in regular use, fall in a single pass even little leaves, so that the catch bag rarely needs to be emptied.
Description
Es gibt eine Vielzahl von Laubsauggeräten. Mit Benzin angetriebene verursachen starken Lärm. Auch elektrisch vom Stromnetz betriebene Sauger sind sehr laut. Leiser, aber nicht sehr leise, sind Geräte mit Akkuantrieb. Deren elektrische Leistung beträgt so um die 100 Watt. Diese Leistung ist erforderlich, weil sie mit einem etwa 1m langen Saugrohr versehen sind.There are a variety of leaf suction devices. Fueled by gasoline cause strong noise. Even electrically powered by the mains suckers are very loud. Quieter, but not very quiet, are devices with accumulator drive. Their electric power is about 100 watts. This power is required because they are equipped with a suction pipe about 1m long.
Wesentlich weniger Leistung ist notwendig, wenn der Saugantrieb wenige Zentimeter über dem Boden liegt und so das Sauggut vom Einlaß bis zum Fangsack nur kurze Wege zurücklegen muß. Dann sinkt der Leistungsbedarf auf etwa 25 Watt. Das gewährleistet zudem einen leisen Betrieb.Significantly less power is necessary when the suction drive is a few inches above the ground and so the suction material from the inlet to the collecting bag only has to travel short distances. Then the power requirement drops to about 25 watts. This also ensures quiet operation.
Der geringere elektrische Leistungsbedarf als auch die Lärmminderung sind mit dem Schutzanspruch 1 erreicht.The lower electrical power consumption and the noise reduction are achieved with the protection claim 1.
Besonders vorteilhaft ist die Verwendung des Gerätes, wenn man den Rasen durch häufiges mähen kurz hält. Die gleichmäßige Rasenoberfläche erleichtert dem Sauggerät seine Funktion. Somit ist das Sauggerät von besonderem Vorteil in Kombination mit einem Mähroboter.Particularly advantageous is the use of the device, if you keep the lawn short by frequent mowing. The uniform lawn surface facilitates the function of the suction device. Thus, the suction device is of particular advantage in combination with a robotic lawnmower.
Der Stromverbrauch des Sauggerätes entspricht etwa dem eines Mähroboters. Das Sauggerät läßt sich von Hand über die Rasenfläche schieben oder ziehen.The power consumption of the suction device corresponds approximately to that of a robotic lawnmower. The suction device can be pushed or pulled over the lawn by hand.
Sauggerät und Roboter lassen sich aber auch zu einem Gerät zusammen fassen. Dann benötigt man für den gemeinsamen Betrieb einen etwas größeren Akku.However, the suction device and robot can also be combined into one device. Then you need a slightly larger battery for joint operation.
Die kleinen Grasschnipsel, die der Mähroboter bei regelmäßigem Mähen erzeugt, fallen tief auf die Grasnarbe und werden vom Sauggerät kaum erfasst, wohingegen die größeren Laub- und Blütenblätter in Wirbelbewegung leicht eingesaugt und gleichzeitig durch die scharfkantigen und hochtourig drehenden Propeller zerschreddert werden. Wenn das Gerät bezüglich der Häufigkeit gemäß den Empfelungen der Roboterhersteller eingesetzt wird, fällt während eines Mähdurchgangs in der Regel relativ wenig Laub an. Der Fangsack muss dann nicht sehr oft geleert werden.The small grass clippings produced by the robotic lawnmower during regular mowing, fall low on the grass and are hardly detected by the suction device, whereas the larger leaves and petals are easily sucked into swirling motion and shredded by the sharp-edged and high-speed rotating propeller. When the device is used in frequency according to the recommendations of the robot manufacturers, relatively few leaves usually fall during a mowing pass. The collecting bag then does not have to be emptied very often.
Beim Mähbetrieb wird das Sauggerät nur eingeschaltet, wenn sich Blätter auf der Grasoberfäche befinden. Dazu ist das Gerät mit Lichtsensoren versehen, die die Blätter erkennen lassen und das Sauggerät für eine gewisse Zeit einschalten. Wird ein Blatt erkannt, werden die in der Nähe liegenden Blätter ebenfalls eingesogen. Der Vorgang wiederholt sich bei jedem erkannten Blatt. Da das Sauggerät nur zeitweilig arbeitet, wird der Akku geschont und es kann länger gemäht werden.During mowing operation, the suction device is only switched on when there are leaves on the grass surface. For this purpose, the device is provided with light sensors, which can detect the leaves and turn on the suction device for a certain time. If a leaf is detected, the nearby leaves are also sucked in. The process is repeated for every leaf detected. Since the suction device works only temporarily, the battery is spared and it can be mowed longer.
