Description

Die Erfindung betrifft einen Staubsauger mit einem motorbetriebenen Gebläse zum Erzeugen eines Unterdrucks, mit einer Steuereinrichtung zur Ansteuerung des Gebläsemotors, mit einem ersten fußbetätigbaren Schalter zum Ein- und Ausschalten der Stromzufuhr und mit mindestens einem zweiten fußbetätigbaren Schalter zum Einstellen eines Gebläseleistungswerts, wobei die Steuereinrichtung einen Datenspeicher zum Abspeichern des mittels des mindestens einen zweiten fußbetätigbaren Schalters eingestellten Gebläseleistungswerts umfasst, und wobei die Steuereinrichtung nach dem Betätigen des ersten Schalters den Gebläsemotor derart ansteuert, dass die erzeugte Gebläseleistung dem abgespeicherten Gebläseleistungswert entspricht.The invention relates to a vacuum cleaner with a motor-driven blower for generating a negative pressure, with a control device for controlling the blower motor, with a first foot-operated switch for switching on and off the power supply and at least one second foot-operated switch for setting a blower power value, wherein the control means a Data memory for storing the set by means of the at least one second foot-operated switch fan performance value comprises, and wherein the control device after actuation of the first switch, the fan motor controls such that the blower power generated corresponds to the stored blower power value.

Ein solcher Staubsauger wird von der Anmelderin hergestellt und unter der Typbezeichnung S5311 vertrieben. Bei nahezu allen Bodenstaubsaugern erfolgt das Einschalten der Stromzufuhr zum Staubsauger mittels eines fußbetätigbaren Schalters, wobei in der Regel eine Taste verwendet wird, die nach einmaliger Betätigung ein Schaltsignal an die Steuereinrichtung abgibt. Das Abschalten der Stromzufuhr erfolgt dann durch nochmaliges Treten auf die Taste. Die Einstellung eines Gebläseleistungswerts kann auf unterschiedliche Art erfolgen. In den einfachsten Varianten ist ein Drehschalter vorhanden, über den der Wert eingestellt wird, komfortablere Ausführungsformen besitzen +/- Tasten, d. h. zwei weitere Schalter, mit denen der Gebläseleistungswert erhöht oder abgesenkt wird. Auch fußbetätigbare Schieberegler sind denkbar. Insbesondere bei Staubsaugern mit +/- Tasten kann es dazu kommen, dass bei Betätigung der Taste zum Einschalten des Gebläsemotors versehentlich eine der Tasten zum Ändern des Gebläseleistungswerts mit betätigt wird. Da Benutzer von Staubsaugern den einmal eingestellten Gebläseleistungswert nur selten ändern, wird dessen versehentliche Änderung nicht registriert und der Staubsauger arbeitet mit einer unerwünschten Gebläseleistung.Such a vacuum cleaner is manufactured by the applicant and sold under the type designation S5311. In almost all vacuum cleaners, the power supply to the vacuum cleaner by means of a fußbetätigbaren switch, wherein usually a button is used, which emits a single signal after a single actuation signal to the control device. Switch off the power supply then by pressing again on the button. The setting of a fan power value can be done in different ways. In the simplest variants there is a rotary switch over which the value is set, more comfortable embodiments have +/- keys, d. H. two additional switches that increase or decrease the blower output. Foot-operated sliders are also conceivable. Especially with vacuum cleaners with +/- buttons, it may happen that when you press the button to turn on the fan motor accidentally one of the buttons to change the fan power value is pressed with. Since users of vacuum cleaners rarely change the set fan power value, its accidental change is not registered and the vacuum cleaner is operating at an undesirable blower output.

Der Erfindung stellt sich somit das Problem, die Bedienung bei einem Staubsauger der eingangs genannten Art zu verbessern.The invention thus raises the problem of improving the operation in a vacuum cleaner of the type mentioned.

Erfindungsgemäß wird dieses Problem durch einen Staubsauger mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention this problem is solved by a vacuum cleaner with the features of claim 1. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

Die mit der Erfindung erreichbaren Vorteile ergeben sich dadurch, dass die Steuereinrichtung eine Auswerteschaltung umfasst, welche bei annähernd gleichzeitiger Betätigung des ersten Schalters und des zweiten Schalters ein Abspeichern eines eingestellten Gebläseleistungswerts verhindert. Dabei wird davon ausgegangen, dass eine solche gleichzeitige Betätigung der beiden Schalter fast immer versehentlich erfolgt und deshalb unerwünscht ist. Eine versehentliche Änderung des Gebläseleistungswerts wird somit durch die Auswerteschaltung wirkungsvoll verhindert.The advantages achievable with the invention result from the fact that the control device comprises an evaluation circuit which, with approximately simultaneous actuation of the first switch and the second switch, stores a set blower power value prevented. It is assumed that such a simultaneous actuation of the two switches almost always happens accidentally and therefore undesirable. An accidental change in the fan power value is thus effectively prevented by the evaluation circuit.

Die Auswerteschaltung kann eine Verzögerungsschaltung umfassen, welche den eingestellten Gebläseleistungswert erst nach einem vorgegebenen Zeitraum abspeichert. Hierdurch wird eine versehentliche Änderung des Gebläseleistungswerts beim Ausschalten der Stromzufuhr verhindert. Durch die Zeitverzögerung wird erreicht, dass bei gleichzeitiger Betätigung des ersten und zweiten Schalters die Speicherung des Gebläseleistungswerts auf einen Zeitpunkt verlagert wird, an dem die Stromzufuhr bereits abgeschaltet ist. Demzufolge ist die Steuereinrichtung nicht mehr arbeitsfähig und die Speicherung unterbleibt. Dies ist mit einfachen technischen Mitteln lösbar.The evaluation circuit may comprise a delay circuit which stores the set fan power value only after a predetermined period of time. This prevents an inadvertent change in the blower power value when the power is turned off. The time delay ensures that the simultaneous operation of the first and second switches, the storage of the fan power value is shifted to a time at which the power supply is already off. As a result, the control device is no longer able to work and the storage is omitted. This can be solved by simple technical means.

Die Auswerteschaltung kann zusätzlich, oder auch nur alternativ Mittel umfassen, die das Abspeichern eines eingestellten Gebläseleistungswerts verhindern, wenn die Zeit zwischen dem Betätigen des ersten und des zweiten Schalters einen vorgegebenen Mindestzeitraum unterschreitet. Hierdurch wird die Einstellung eines neuen Gebläseleistungswerts erst dann zugelassen, wenn zwischen dem Einschalten der Stromzufuhr und der Einstellung eine gewisse Zeit vergangen ist. Hier reichen wenige Sekunden aus, um den möglichen Fehlerfall zu vermeiden.In addition, or alternatively, the evaluation circuit may comprise means for preventing the storage of a set blower power value if the time between the actuation of the first and of the second switch falls below a predetermined minimum time period. This will allow the setting of a new blower power value only after a certain amount of time has elapsed between turning on the power and setting. Just a few seconds are enough to avoid a possible error.

Es ist zweckmäßig, wenn der Datenspeicher als nichtflüchtiger Speicher ausgebildet ist. Hierdurch wird der Staubsauger auch bei jedem Neustart mit dem bei der vorherigen Nutzung eingestellten Gebläseleistungswert gestartet.It is expedient if the data memory is designed as a non-volatile memory. This will also start the vacuum cleaner every time it is restarted with the fan power set in the previous use.

Außerdem ist es zweckmäßig, wenn zwei zweite Schalter vorhanden sind, wobei der Gebläseleistungswert mit einem Schalter erhöht und mit dem anderen Schalter verringert werden kann.In addition, it is expedient if two second switches are present, wherein the blower power value can be increased with one switch and reduced with the other switch.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen rein schematisch dargestellt und wird nachfolgend näher beschrieben. Es zeigen:

Figur 2

An embodiment of the invention is shown purely schematically in the drawings and will be described in more detail below. Show it:
FIG. 1
a vacuum cleaner in perspective and
FIG. 2
the control of the fan motor as a block diagram.

Figur 1 zeigt das Gehäuse eines an sich bekannten Bodenstaubsaugers 1. Dieser besitzt im Gehäuseinneren ein Gebläse 2, welches lediglich in Figur 2 symbolisch dargestellt ist und durch einen Gebläsemotor 3 angetrieben wird. Der Staubsauger 1 wird mit Netzstrom 4 betrieben und besitzt zu diesem Zweck ein in Figur 1 nicht erkennbares Netzanschlusskabel 5. Im hinteren oberen Bereich ist der Staubsauger mit einem Bedienfeld 6 ausgestattet, in dem sich insgesamt vier Schalter 7 bis 10 befinden. Alle Schalter 7 bis 10 sind als fußbetätigbare Tritttasten ausgebildet. Eine Einschalttaste 7 dient zum Ein- und Ausschalten der Stromzufuhr zum Gerät, eine Kabeleinholtaste 8 zum Betätigen einer Aufwickelvorrichtung für das Netzkabel 5. Im Bedienfeldinneren befinden sich zwei weitere Tasten. Über die linke, eine sogenannte Minustaste 9, wird ein eingestellter Gebläseleistungswert verringert. Die rechte Taste, eine Plustaste 10 dient zur Erhöhung des Werts. FIG. 1 shows the housing of a known per se vacuum cleaner 1. This has inside the housing a blower 2, which only in FIG. 2 is shown symbolically and is driven by a blower motor 3. The vacuum cleaner 1 is operated with mains power 4 and has for this purpose a in FIG. 1 unrecognizable mains connection cable 5. In the rear upper area of the vacuum cleaner is equipped with a control panel 6, in which a total of four switches 7 to 10 are located. All switches 7 to 10 are designed as Fußbetätigbare kick buttons. A power button 7 is used to turn on and off the power to the device, a cable recovery button 8 to operate a rewinder for the power cord 5. In the control panel interior are two more buttons. Via the left-hand, a so-called minus key 9, a set blower power value is reduced. The right button, a plus button 10 is used to increase the value.

Unter dem Bedienfeld 6 ist eine Steuereinrichtung 11 angeordnet, die nur in Figur 2 symbolisch dargestellt ist. Die Steuereinrichtung 11 umfasst eine Auswerteschaltung 12, einen Datenspeicher 13 und eine Gebläsemotorsteuerung 14. Die Auswerteschaltung umfasst eine Verzögerungsschaltung 15 und einen Vergleicher 16.Under the control panel 6, a control device 11 is arranged, which is only in FIG. 2 is shown symbolically. The control device 11 comprises an evaluation circuit 12, a data memory 13 and a blower motor control 14. The evaluation circuit comprises a delay circuit 15 and a comparator 16.

Die Ansteuerung des Gebläsemotors 3 erfolgt mit einer variablen Leistung. Hierzu dient beispielsweise eine Phasenanschnittsteuerung als Gebläsemotorsteuerung 14, welche die Netzspannung 4 in Abhängigkeit von dem im Datenspeicher13 befindlichen Gebläseleistungswert anpasst. Die Veränderung des Gebläseleistungswerts im Datenspeicher 13 ist über die Plus- und Minustasten 9, 10 möglich. Die eingestellten Werte werden jedoch nicht direkt in den Datenspeicher 13 geschrieben, hier ist die Auswerteschaltung 12 zwischengeschaltet. Diese kontrolliert zunächst einmal mit Hilfe des Vergleichers 16, ob innerhalb eines vorgegebenen Zeitraums auch die Einschalttaste 7 betätigt wurde. Ist dies der Fall, geht die Auswerteschaltung 12 von einer ungewollten Betätigung der Plus- oder Minustaste 9 bzw. 10 beim Einschalten der Stromzufuhr (Betätigung der Taste 7) aus und schreibt den eingestellten Gebläseleistungswert nicht in den Datenspeicher 13. Ist der Zeitraum verstrichen, geht die Auswerteschaltung 12 von einer gewollten Änderung des Gebläseleistungswerts aus. Das Überschreiben des neuen Werts in den Datenspeicher 13 erfolgt dann mit einer Zeitverzögerung, welche durch die Verzögerungsschaltung 15 verursacht wird. So wird sichergestellt, dass bei einem ungewollten Betätigen der Plus- oder Minustaste 9 bzw. 10 beim Ausschalten der Stromzufuhr (Betätigung der Taste 7) die Speicherung unterbleibt, weil die Steuereinrichtung 11 dann bereits stromlos ist.The control of the fan motor 3 is carried out with a variable power. For this purpose, for example, serves a phase control as a blower motor controller 14, which adjusts the mains voltage 4 in response to the blower power value located in the data memory 13. The change of the blower power value in the data memory 13 is possible via the plus and minus buttons 9, 10. However, the set values are not written directly into the data memory 13, here the evaluation circuit 12 is interposed. This first checks, with the aid of the comparator 16, whether the switch-on key 7 was also actuated within a predetermined period of time. If this is the case, the evaluation circuit 12 goes from an unwanted operation of the plus or minus button 9 or 10 when switching on the power supply (pressing the button 7) and does not write the set fan power value in the data memory 13. If the period has elapsed, goes the evaluation circuit 12 of a desired change of the blower power value from. The overwriting of the new value in the data memory 13 then takes place with a time delay, which is caused by the delay circuit 15. This ensures that in the event of an unwanted actuation of the plus or minus button 9 or 10 when switching off the power supply (actuation of the button 7), the storage is omitted, because the control device 11 is then already de-energized.

Als Datenspeicher 13 wird vorzugsweise ein nichtflüchtiger Speicher verwendet.As the data memory 13, a nonvolatile memory is preferably used.
