Description
Staubsauger Staubsauger weisen heute eine verhältnismäßig hohe Saugleistung auf, die an sich erwünscht ist. Nun gibt es aber eine Vielzahl von Bodenbelägen unterschiedlicher Gewebeart, für die eine gleiche hohe Saugleistung nicht vorteilhaft ist. Ferner verwendet man Staubsauger nicht nur zur Reinigung des Bodens, sondern auch für Polstermöbel, Kleidungsstücke, Gardinen u.dgl., für die geringere Saugleistungen zweckmäßig sind, damit der Stoff nicht in die Saugdüse hineingezogen wird.Vacuum cleaners Vacuum cleaners nowadays have a relatively high suction power that is desirable in itself. But there is a wide variety of floor coverings different types of tissue for which the same high suction power is not advantageous is. Furthermore, vacuum cleaners are not only used to clean the floor, but Also for upholstered furniture, items of clothing, curtains and the like, for the lower suction power are useful so that the fabric is not drawn into the suction nozzle.
Es# besteht somit der Wunsch, bei einem Staubsauger mit an sich hoher Saugleistung diese dem jeweils abzusaugenden Gegenstand anzupassen. Dies wird erfindungsgemäß dadurch erreicht, daß die Saugleistung des Gerätes mittels einer elektronischen Drehzahlsteuerung für den Gebläsemotor veränderbar ist. Bekanntlich läßt sich mit einer elektroniæchen Steuerung die Drehzahl eines Motors beliebig variieren, so daß man bei dem erfindungsgemäßen Staubsauger die Saugleistung mittels eines Drehknopfes mühelos jeweils dem abzusaugenden Gewebe oder dem Boden anpassen kann.There is thus # a desire in a vacuum cleaner with a high Suction power to adapt this to the object to be vacuumed. This is according to the invention achieved in that the suction power of the device by means of an electronic Speed control for the fan motor is changeable. As is well known, can be with an electronic control can vary the speed of a motor as desired, so that in the vacuum cleaner according to the invention, the suction power by means of a rotary knob can effortlessly adapt to the tissue to be aspirated or the floor.
Bei Verwendung eines Triac in der elektronischen Steuerung muß darauf geachtet werden, daß der Triac sich nicht zu sehr erwärmt.If a triac is used in the electronic control, care must be taken care must be taken that the triac does not heat up too much.
Dies ist insbesondere bei verhältnismäßig hohen Strömen, wie sie. bei einem Staubsaugerantrieb notwendig sind, der Fall. Bisher wurde ein Triac mit besonderen, großen Kühlflächen versehen, die zusätzlichen Raum benötigen. Ein weiterer Erfindungsgedanke besteht deshalb darin, den Triac im Unterdruckraum, d.h. also im Filterraum des Gerätes anzuordnen. Er wird auf diese Weise vom kühlen Saugluftstrom umspült, so daß eine-0berhitzung des Triac nicht möglich ist.This is especially true with relatively high currents, like them. are necessary with a vacuum cleaner drive, the case. Previously a triac was used with Provide special, large cooling surfaces that require additional space. Another The idea of the invention therefore consists in placing the triac in the negative pressure space, i.e. therefore to be arranged in the filter room of the device. In this way it is removed from the cool suction air flow washes around, so that overheating of the triac is not possible.
Ein Ausführungsbeispiel der Erfindung ist im folgenden an Hand der Zeichnung beschrieben. Mit 1 ist das Gehäuse eines 3taubsaugers bezevehnet, welches in bekannter Weise durch eine Trennwand 2 in einen den Filterbeutel 3 aufnehmenden Unterdruckraum 4 und einen das Gebläseaggregat 5 enthaltenden Überdruckraum 6 unterteilt ist. Im tberdruck- oder Motorraum 6 ist der Ein- und Ausschalter 7 untergebracht sowie gemäß der Erfindung eine elektronische Steuerung 8, mit deren Hilfe - durch Verdrehen des Knopfes 9 - die Drehzahl des Gebläsemotors und damit die Saugleistung des Gerätes veränderbar ist. Dies kann stufenlos oder in Stufenschaltung erfolgen.An embodiment of the invention is shown below with reference to the Drawing described. With 1 the housing of a 3 vacuum cleaner is denoted, which in a known manner through a partition 2 into a filter bag 3 receiving Underpressure space 4 and an overpressure space 6 containing the blower unit 5 are subdivided is. The on / off switch 7 is housed in the overpressure or engine compartment 6 as well as according to the invention an electronic control 8, with the help of which - by Turning the button 9 - the speed of the fan motor and thus the suction power of the device can be changed. This can be done steplessly or in step switching.
Zu den elektronischen Steuerelementen gehört ein Triac 10. Dieser ist, wie schon erwähnt, wärmeempfindlich und wird deshalb nicht mit den übrigen elektronischen Elementen im Motorraum 6, sondern im Unterdruckraum 4 untergebracht, so daß er von der kühlen Saugluft umspült wird. Die Trennwand 2 ist zu diesem Zweck mit einem hohlzylindrischen Ansatz 11 versehen, in den der Triac 10 eingesetzt wird. Da man bei abgenommenem Deckel 12 des Staubsaugers in den Filterraum 4 hineinlangen kann und die Außenwand des Triac stromführend ist, ist der Ansatz 11 nach dem Filterraum zu verschlossen. Zweckmäßig verschließt man nach dem Einsetzen des Triac in den Ansatz 11 auch dessen nach den Motorraum hin gelegene Öffnung mit einem Pfropfen 13 od. dgl., damit die im Raum 6 befindliche warme Luft keinen Einfluß auf den Triac hat.A triac 10 belongs to the electronic control elements is, as already mentioned, heat-sensitive and therefore does not interfere with the rest electronic elements in the engine compartment 6, but housed in the negative pressure compartment 4, so that it is washed around by the cool suction air. The partition 2 is for this purpose provided with a hollow cylindrical extension 11 into which the triac 10 is inserted. Since you reach into the filter chamber 4 with the cover 12 of the vacuum cleaner removed can and the outer wall of the triac is live, the approach 11 is after the filter space too closed. It is useful to close after inserting the triac into the Approach 11 also has its opening with a plug towards the engine compartment 13 or the like, so that the warm air in room 6 does not affect the triac Has.
Man kann selbstverständlich auch das gesamte elektronische Steuerelement 8 im Unterdruckraum 4 unterbringen. Dies erfordert jedoch eine besondere Abdeckung dieses Elementes, damit bei geöffnetem Gerät die Bedienungsperson nicht an die stromführenden Teile greifen kann. Ferner müßte die Öffnung für die Achse des Drehknopfes 9 im Unterdruckraum luftdicht gemacht werden. Aus diesem Grund ist es vorteilhafter, lediglich nur den Triac im Unterdruckraum 4 und die übrigen Steuerelemente im Motorraum 6 unterzubringen.You can of course also use the entire electronic control 8 in the vacuum chamber 4. However, this requires a special cover this element, so that when the device is open, the operator does not touch the live Can grip parts. Furthermore, the opening for the axis of the rotary knob 9 in the Vacuum space can be made airtight. For this reason it is more advantageous to only the triac in the vacuum chamber 4 and the other controls in the engine room 6 to accommodate.
