Schadstoffabhängig geführte Motordrehzahl für Luftfiltergeräte "·Pollutant-dependent engine speed for air filter devices "·

Er Läuterungen :Explanations :

Es sind Filtergeräte bekannt, bei denen die Raumluft mit Hilfe eines Gebläses zwangsweise über ein geeignetes Filter geführt wird, mit dem Ziel, schädliche oder unangenehme Luftbestandteile zurückzuhalten.There are known filter devices in which the room air is forced through a suitable filter with the help of a fan, with the aim of retaining harmful or unpleasant air components.

Es sind ferner Filtergeräte bekannt, bei denen ein geeigneter Sensor die schädlichen oder belästigenden LuftinhaItsstoffe erkennt und in geeignete Form, z.B. über eine Leuchtdiodenkette, zur Anzeige bringt.Filter devices are also known in which a suitable sensor detects harmful or annoying air constituents and displays them in a suitable form, e.g. via a chain of LEDs.

Weiter sind Filtergeräte der oben beschriebenen Art bekannt, in denen ein weiterer Sensor die Luftgüte nach Passieren des Filters überwacht und ebenfalls in geeigneter Form zur Anzeige bringt.Furthermore, filter devices of the type described above are known, in which a further sensor monitors the air quality after it has passed through the filter and also displays it in a suitable form.

Ferner sind Filtergeräte der oben beschriebenen Art bekannt, bei denen die Drehzahl des Ventilators einstellbar ist. Üblicherweise bedient man sich hier der sogenannten Impuls-Weiten-Modulat i on.Furthermore, filter devices of the type described above are known, in which the speed of the fan is adjustable. Usually, the so-called pulse width modulation is used here.

Eine bevorzugte Ausführung zeigt schematisch Figur 1. Ein Timer (2) erzeugt periodisch Scha 11 i rupu I se , die einen FETMOS-Transistör (4) entsprechend durchsteuern, wodurch der Luftermotor (3) angesteuert wird.A preferred embodiment is shown schematically in Figure 1. A timer (2) periodically generates pulses which accordingly control a FETMOS transistor (4), thereby controlling the fan motor (3).

Die Leistung, die dem Motor zur Verfügung gestellt wird, ergibt sich aus dem Impuls-Pausen-Verhältnis der vom Timer (2) generierten Impulse.The power provided to the motor is determined by the pulse-pause ratio of the pulses generated by the timer (2).

Das Impuls-Pausenverhältnis kann über einen Einsteller <1) eingestellt werden, der üblicherweise nach außen gefuhrt ist und als brehzah(e&igr; nsteI Ier bezeichnet ist. The pulse-pause ratio can be adjusted using an adjuster (<1) which is usually located on the outside and is referred to as a pulse-pause adjuster.

Zur Oedek11erung der Schadstoffante&igr; I e wird überI &igr; eherwe&igr; se ein pa I I adiumdo11 er ter Z &igr;nn-Di&ogr;&khgr; &igr;d-Sensor (5) eingesetzt, der mit einem ohmschen Widerstand zusammen einen Spannungsteiler bildet, wobei sich eine schadstoffabhang &igr; ge Sensorspannung (8) bildet, die über eine geeignete Anzeigevorrichtung (7) angezeigt wird.To detect the pollutant content, a zinc-dioxide sensor (5) containing a lithium ion battery is used, which together with an ohmic resistor forms a voltage divider, whereby a pollutant-dependent sensor voltage (8) is formed, which is displayed via a suitable display device (7).

Lehre der Erfindung ist es, die Seisorspannung zu benutzen, um die Motordrehzah&iacgr; zu beeinflussen.The teaching of the invention is to use the sensor voltage to influence the motor speed.

Diese Verknüpfung ist äußerst vorteilhaft, wenn bspw. das Gerät nachts in einem Krankenzimmer betrieben werden sol'..This connection is extremely advantageous if, for example, the device is to be operated at night in a hospital room.

Aufgrund der unvermeidbaren Betriebsgeräusche ist es wünschenswert, die Motordrehzahl auf möglichst niedrigem Niveau zu ha I ten.Due to the unavoidable operating noise, it is desirable to keep the engine speed as low as possible.

Kommt es während der Nacht jedoch zu einem Schadstoffans11 eg, z.B. durch Industrieemissionen, Verkehrsemissionen oder menschliche StoffwechseIprodukte, wird die eingestellte, niedrige Drehzahl 'unter Umständen nicht das ausreichende Fordervo I umen haben.However, if there is a pollutant build-up during the night, e.g. due to industrial emissions, traffic emissions or human metabolic products, the set low speed may not provide sufficient air flow.

In diesem Fall ist es wünschenswert, wenn die Förderleistung, d.h. die Drehzahl des Lüftermotors, angehoben wird. In this case, it is desirable to increase the air flow, i.e. the speed of the fan motor.

Erfindungsgemäß erfolgt dies, indem die Sensoritpannung (6) über eine Koppeldiode (6) auf den sogenannten Kontrolleingang des Impuls-Generators (2) geleitet wird, der in der bevorzugten Ausführung durch einen Timer-Baustein NE 555 gebtIdet ist.According to the invention, this is done by the sensor voltage (6) being fed via a coupling diode (6) to the so-called control input of the pulse generator (2), which in the preferred embodiment is provided by a timer module NE 555.

Bei Anstieg der Üensorspannung wird über diese Koppeidiode die Geber-Spannung des Timers so verändert, daß das Impuls-Pausenverha I t&eegr; &igr;s zulasten des Pausenante &igr; I s verändert wird, mit der Wirkung, daß damit die dem Motor zur Verfügung gestellte Leistung steigt, was logischerweise die Förderleistung erhöht.When the sensor voltage increases, the sensor voltage of the timer is changed via this coupling diode in such a way that the pulse-pause ratio I t&eegr;&igr;s is changed at the expense of the pause ratio &igr; I s, with the effect that the power made available to the motor increases, which logically increases the delivery capacity.

Gegenstand der Erfindung ist demnach die Verknüpfung des Sensorsignals mit der Lüfterdrehzah I .The subject of the invention is therefore the linking of the sensor signal with the fan speed I .

Die Erfindung bezieht sich auf diese prinzipielle Aussage, wobei neben der aufgezeigten Lösungsmethode selbstverständlich andere elektronische Konfigurationen möglich sind, auf die die Lehre der Erfindung im einzelnen nicht eingeht.The invention relates to this fundamental statement, whereby in addition to the solution method shown, other electronic configurations are of course possible, which the teaching of the invention does not go into in detail.

Ein typisches Beispiel ist in Figur 1 gezeigt, wobei die Ziffern folgende Bauteile bzw. Baugruppen umfassen :A typical example is shown in Figure 1, where the numbers include the following components or assemblies:

Schutzansprtich:Protection claim: £Luftfiltergerät&rgr; vorzugsweise für Wohnräume, mit eingebauter Filtereinheit und eingebautem Ventilator zur Luftförderung, wobei die Förderleistung durch einen auf der Frontseite des Filtergerätes angebrachten Einsteller mit Hilfe eines elektronischen Reglers einstellbar ist, dadurch gekennzeichnet, daß in das Luftfiltergerat im Bereich der Luftansaugung ein schadstoffempfindlicti&r Sensor eingebaut ist, der eine dem Schadstoffgehalt proportionale Sensorspannung (8) abgibt, die über eine elektrische Koppeldiode (6) auf den 3t*uereingang eines handelsüblichen Timer-Bausteins (Multivibrator) geleitet wird, was zur Folge hat, daß das Impuls/Pausen-Verhältnis des Multivibrators sich mit zunehmender Sensorspannung verringert, und damit eine Erhöhung der Förderleistung bewirkt. Die elektronische Schaltung ist auf einer gedruckten Schaltung aufgebaut, die in einem den technischen Regeln entsprechendem Schutzgehäuse innerhalb des Filters montiert ist.£Air filter device´ preferably for living spaces, with built-in filter unit and built-in fan for air conveyance, whereby the conveyance can be adjusted by an adjuster on the front of the filter device with the aid of an electronic controller, characterized in that a pollutant-sensitive sensor is built into the air filter device in the area of the air intake, which emits a sensor voltage (8) proportional to the pollutant content, which is fed via an electrical coupling diode (6) to the control input of a commercially available timer module (multivibrator), which results in the pulse/pause ratio of the multivibrator decreasing with increasing sensor voltage, thus increasing the conveyance. The electronic circuit is built on a printed circuit which is mounted in a protective housing in accordance with technical regulations inside the filter.
