The scope of the invention also includes all combinations at least two of the in the description, the claims and / or the features indicated in the figures.
Der Erfindung liegt die Erkenntnis zugrunde, dass die Lebensdauer der Akkumulatoranordnung in hohem Maße von deren thermischer Belastung abhängt. Hohe Temperaturen von beispielsweise über 35°C verringern dabei die Lebensdauer der Akkumulatoranordnung, d. h. deren Speicherkapazität, erheblich. Wird das Gartengerät nach dessen Nutzung beispielsweise einer direkten Sonneneinstrahlung ausgesetzt, erwärmt sich die mindestens einen Akkumulator aufweisende Akkumulatoranordnung sehr stark und nimmt dadurch auf Dauer Schaden. Der Erfindung liegt daher der Gedanke zugrunde, eine elektrisch betriebene Kühleinrichtung zum Kühlen der Akkumulatoranordnung vorzusehen, wobei die Kühleinrichtung zum Schonen der Akkumulatoranordnung mit elektrischer Energie von einer Solarzellenanordnung mit mindestens einer Solarzelle versorgt wird. Die Solarzellenanordnung kann dabei beispielsweise auf einem Gehäuse des Gartengerätes angeordnet oder Teil des Gehäuses sein. Die Versorgung der Kühleinrichtung mit elektrischer Energie aus der Solarzellenanordnung ermöglicht eine dauerhafte Kühlung der Akkumulatoranordnung, insbesondere zu Zeiten großer thermischer Belastung, insbesondere durch direkte Sonneneinstrahlung unab hängig von dem Ladezustand der Akkumulatoranordnung. Eine derartige dauerhafte Kühlung könnte bei einer ausschließlichen Stromversorgung der Kühleinrichtung aus der Akkumulatoranordnung aufgrund deren begrenzten Speicherkapazität nicht (bzw. nur schwerlich) gewährleistet werden.Of the Invention is based on the finding that the life of Accumulator arrangement highly of the thermal Load depends. High temperatures of, for example, over 35 ° C reduce the life of the accumulator, d. H. their storage capacity, considerably. Will the gardening tool after being used, for example, exposed to direct sunlight, the at least one accumulator heats up Accumulator arrangement very strong and thus takes permanent damage. The invention is therefore based on the idea of an electric operated cooling device for cooling the accumulator assembly provide, wherein the cooling device for protecting the accumulator with electrical energy from a solar cell array with at least a solar cell is supplied. The solar cell arrangement can for example, on a housing of the gardening tool be arranged or part of the housing. The supply the cooling device with electrical energy from the solar cell array allows permanent cooling of the accumulator assembly, especially at times of great thermal stress, in particular by direct sunlight irrespective of the state of charge the accumulator arrangement. Such permanent cooling could be at an exclusive power supply the cooling device from the accumulator assembly due their limited storage capacity is not (or only with difficulty) be guaranteed.
In Weiterbildung der Erfindung ist mit Vorteil vorgesehen, dass die Versorgung der Kühleinrichtung mit elektrischer Energie von der Solarzellenanordnung direkt, d. h. ohne Zwischenschaltung der Akkumulatoranordnung erfolgt, so dass die Akkumulatoranordnung während der Stromversorgung der Kühleinrichtung aus der Solarzellenanordnung in keiner Weise tangiert wird. Selbstverständlich ist es auch denkbar, über die Solarzellenanordnung die Akkumulatoranordnung mit elektrischer Energie zu speisen und die Kühleinrichtung elektrisch mit der Akkumulatoranordnung zu verbinden.In Development of the invention is provided with advantage that the Supplying the cooling device with electrical energy from the solar cell array directly, d. H. without interposition the accumulator arrangement takes place, so that the accumulator arrangement during the power supply of the cooling device from the solar cell array is affected in any way. Of course It is also conceivable, via the solar cell array the Accumulator to feed with electrical energy and the Cooling device electrically with the accumulator assembly connect to.
Mit Vorteil ist in Ausgestaltung der Erfindung vorgesehen, dass die Kühleinrichtung nicht lediglich elektrisch mit der Solarzellenanordnung, sondern zusätzlich mit der Akkumulatorvorrichtung verbunden ist, so dass die Kühleinrichtung (bei Bedarf) mit elektrischer Energie aus Akkumulatorvorrichtung versorgbar ist, insbesondere um eine lückenlose Kühlung der Akkumulatoranordnung sicherzustellen.With Advantage is provided in an embodiment of the invention that the Cooling device not only electrically connected to the solar cell arrangement, but additionally connected to the accumulator device, so that the cooling device (if necessary) with electric Energy from accumulator device can be supplied, in particular for a complete cooling of the accumulator assembly sure.

Bei einer derartigen Ausgestaltungsform wird die Akkumulatoranordnung nur zu den Zeiten zur Versorgung der Kühleinrichtung mit elektrischer Energie benötigt, in denen sie sowieso zum Antrieb eines Werkzeugs (z. B. Schneidmesser) benötigt wird. In einer Ruhephase (Nichtbenutzung des Gartengerätes) ist dann für die Versorgung der Kühleinrichtung mit elektrischer Energie ausschließlich die Solarzellenanordnung zuständig. Parallel kann die Akkumulatoranordnung von der Solarzellenanordnung aufgeladen werden. Zusätzlich oder alternativ ist die Akkumulatoranordnung bzw. eine elektrisch mit der Akkumulatoranordnung verbundene Ladervorrichtung mit elektrischer Energie aus einem stationären Stromnetz versorgbar.Preference is given to an embodiment in which the cooling device is supplied (exclusively) with electrical energy from the accumulator arrangement during operation of the garden implement and is supplied with electrical energy from the solar cell arrangement when the drive motor is switched off, in particular when the garden implement is switched off in the sun. In such an embodiment, the accumulator assembly is needed only at the times for supplying the cooling means with electrical energy in which it is needed anyway to drive a tool (eg, cutting blade). In a resting phase (non-use of the garden implement) is then responsible for the supply of the cooling device with electrical energy only the solar cell array. In parallel, the accumulator assembly of the solar cells be charged. Additionally or alternatively, the accumulator arrangement or a charging device electrically connected to the accumulator arrangement can be supplied with electrical energy from a stationary power grid.
Zum Umschalten zwischen der Stromversorgung der Kühleinrichtung zwischen Akkumulator und Solarzellenanordnung ist bevorzugt eine erste Steuereinheit vorgesehen, die insbesondere in Abhängigkeit der Betriebsschalterstellung für den Antriebsmotor zwischen den möglichen Energievorsorgungseinrichtungen (Solarzellenanordnung bzw. Akkumulatoranordnung) für die Kühleinrichtung umschaltend ausgebildet ist.To the Switching between the power supply of the cooling device between the accumulator and the solar cell array is preferably one provided first control unit, in particular depending the operating switch position for the drive motor between the possible energy supply facilities (solar cell arrangement or accumulator assembly) for the cooling device is formed switching.
Von besonderem Vorteil ist eine Ausführungsvariante, bei der die Akkumulatoranordnung mit mindestens einem Temperatursensor versehen ist, mit dem die Temperatur der Akkumulatoranordnung unmittelbar in, am oder in direkter Nähe der Akkumulatoranordnung detektierbar ist. Hierdurch wird zu jeder Zeit eine gesicherte Information über die (negative) thermische Belastung der Akkumulatoranordnung erhalten. Bevorzugt ist der mindestens eine Temperatursensor signalleitend, insbesondere mittels eines Signalkabels, mit einer zweiten Steuereinheit verbunden. Diese ist derart ausgebildet, dass die Kühleinrichtung (ausschließlich) bei Überschreiten einer oberen Grenztemperatur der Akkumulatoran ordnung mit elektrischer Energie von der Solarzellenanordnung bzw. der Akkumulatoranordnung versorgt wird.From particular advantage is a variant in which the accumulator assembly provided with at least one temperature sensor is, with the temperature of the accumulator assembly directly detectable in, on or in the immediate vicinity of the accumulator arrangement is. As a result, at any time a secure information about receive the (negative) thermal load of the accumulator assembly. Preferably, the at least one temperature sensor is signal-conducting, in particular by means of a signal cable, with a second control unit connected. This is designed such that the cooling device (only) if an upper one is exceeded Limit temperature of Akkumulatoran order with electrical energy is supplied by the solar cell assembly or the accumulator assembly.
Bevorzugt ist die zweite Steuereinheit derart ausgebildet, dass die Stromversorgung der Kühleinrichtung unterbrochen wird, wenn eine mit dem Temperatursensor gemessene Akkumulatortemperatur eine untere Grenztemperatur unterschreitet, wobei mit Vorteil die untere Grenztemperatur niedriger ist als die obere Grenztemperatur. Selbstverständlich kann die niedere Grenztemperatur auch der oberen Grenztemperatur entsprechen.Prefers the second control unit is designed such that the power supply the cooling device is interrupted when one with the Temperature sensor measured accumulator temperature a lower limit temperature falls below, with advantage the lower limit temperature lower is considered the upper limit temperature. Of course you can the lower limit temperature also correspond to the upper limit temperature.
Aus fertigungs- und montagetechnischen Gründen ist es von Vorteil, wenn beide Steuereinheiten in einem gemeinsamen Steuergerät aufgenommen bzw. angeordnet sind.Out production and assembly reasons, it is advantageous if both control units in a common control unit recorded or arranged.
Um die Kühleinrichtung baulich möglichst einfach zu gestalten, ist die Kühleinrichtung bevorzugt als Luftkühleinrichtung mit mindestens einem elektromotorisch betriebenen Lüfter ausgebildet, der elektrisch leitend zumindest, vorzugsweise ausschließlich, mit der Solarzellenanordnung verbunden ist.Around the cooling device structurally simple To design, the cooling device is preferred as an air cooling device with at least one electric motor operated fan formed, the electrically conductive at least, preferably exclusively, is connected to the solar cell array.
