The sensor controls the via an evaluation control Operation of the extractor hood. This is intended to control the status of the Extractor hood can be reached.
Darüber hinaus ist es bekannt, eine Dunstabzugshaube mit einem Temperaturfühler auszustatten (DE-AS 25 18 750). Es ist weiterhin aus der DE-OS 29 51 409 bekannt, in einer Kochmulde eine sogenannte Restwärmeanzeige anzuordnen, die dem Benutzer den Heizzustand einer Kochplatte bis zum Erreichen ungefährlicher Temperaturwerte signalisiert. In Verbindung damit ist aus der DE-OS 32 45 302 eine Maßnahme bekannt geworden, in einer Dunstabzugshaube einen photoelektrischen Sensor anzuordnen, der auf einen in der Kochplatte befindlichen Signalgeber, z.B. diese Restwärmeanzeige, anspricht.In addition, it is known to equip an extractor hood with a temperature sensor (DE-AS 25 18 750). It is also known from DE-OS 29 51 409, in one Cooking hob to arrange a so-called residual heat indicator that the user The heating status of a hotplate is signaled until safe temperature values are reached. In connection with this, a measure has become known from DE-OS 32 45 302, to arrange a photoelectric sensor in an extractor hood that points to a signal transmitter located in the hotplate, e.g. this residual heat indicator, responds.
Weiterhin ist es bekannt geworden, eine Verbindung zwischen Kochstelle und Dunstabzugshaube übertragungstechnisch bereitzustellen, so daß die Dunstabzugshaube über das Kochfeld bzw. dessen Eingabeorgane und Steuerungen steuerbar ist. Diese Verbindung kann galvanisch, also in Form von Leitungen, oder aber auch leitungslos auf funktechnischen, ultraschalltechnischen, photoelektrischen Wegen durchgeführt werden.Furthermore, it has become known that there is a connection between the hotplate and extractor hood provide transmission technology, so that the extractor hood over the hob or its input elements and controls can be controlled. This connection can be galvanic, i.e. in the form of lines, or also wireless on radio technology, ultrasonic, photoelectric ways are carried out.
Aufbauend auf diesem Stand der Technik ist es Aufgabe der vorliegenden Erfindung, die Funktionalität und die Bedienungsfreundlichkeit einer Dunstabzugsvorrichtung in Verbindung mit einer darunter befindlichen Kochstelle zu verbessern.Based on this prior art, it is an object of the present invention Functionality and ease of use of an extractor hood in combination with a hotplate underneath.
Eine Dunstabzugsvorrichtung, die diesen Anforderungen in hohem Maße genügt, ist erfindungsgemäß dadurch gekennzeichnet, daß die Dunstabzugsvorrichtung mit einer Dunsterfassungssensorik und zusätzlich mit einer eine anhaltende Aktivität der Kochstellenbereichs-Anschaltung mittelbar oder unmittelbar erfassenden Sensorik als Ansteuerorgane einer Steuerschaltung zur Inbetriebnahme der Dunstabzugsvorrichtung ausgestartet ist und daß die Steuerschaltung derart funktionstechnisch konfiguriert ist, daß bei dem von der zusätzlichen Sensorik erfaßten Kriterium einer Kochbereichs-Anschaltung für deren Dauer Steuerschaltungsbereiche für die eine automatische Steuerung unter Einschluß der Dunsterfassungssensorik aktiviert wird.An extractor device that meets these requirements to a high degree is according to the invention characterized in that the extractor device with a Darkness detection sensors and in addition with a continuous activity of the hotplate area connection indirectly or directly sensing sensors as control elements started a control circuit for commissioning the extractor device is and that the control circuit is functionally configured such that at the criterion of a cooking zone connection detected by the additional sensors for the duration of control circuit areas for automatic control under Inclusion of the fog detection sensor system is activated.
Bei einer derartigen Maßnahme in einer Dunstabzugsvorrichtung wird die zusätzliche Sensorik üblicherweise über eine Kleinststromversorgung im Stand-By-Betrieb in Dauereinsatz gehalten, so daß diese zusätzliche Sensorik jederzeit in der Lage ist, ein typisches Kriterium für die Kochbereichs-Anschaltung zu detektieren. Ein derartiges Kriterium kann beispielsweise auch die Restwärmeanzeige sein, was aber voraussetzt, daß bereits eine relevante Heizleistung der Kochstelle zugeführt sein muß. Zweckmäßiger ist es die Inbetriebnahme der Kochstellensteuerung selbst zu detektieren, d. h. beispielsweise auf die Betätigung eines Hauptschalters oder sonstiger Eingabeorgane zu reagieren. Die sich dadurch auch ohne Heizleistungen einstellenden Zustände können mit einfachen bekannten Mitteln erkannt und ausgewertet und somit der zusätzlichen Sensorik der Dunstabzugsvorrichtung zur Verfügung gestellt werden, und zwar vorzugsweise auf funktechnischem Wege. Für die Dauer der Anschaltung der Kochstelle steht demnach dieses Signal zur Verfügung und wird von der zusätzlichen Sensorik der Dunstabzugsvorrichtung registriert und der Steuerschaltung zugeleitet. Ein Ausbleiben dieses Signals veranlaßt die zusätzliche Sensorik dazu, die Automatikfunktion der Dunstabzugsvorrichtung außer Betrieb zusetzen. Für diesen Fall ist vorgesehen, daß die Dunstabzugsvorrichtung handbetätigt auf gewünschte Leistungswerte eingestellt werden kann.With such a measure in an extractor device, the additional Sensor technology usually via a miniature power supply in stand-by mode in continuous use kept so that this additional sensor technology is always able to be a typical Detect criterion for the cooking zone connection. Such a criterion can be, for example, the residual heat indicator, but this requires that already a relevant heat output must be supplied to the hotplate. It is more appropriate Detect commissioning of the hob control yourself, d. H. for example on react to the actuation of a main switch or other input devices. Which This means that states that do not set heating power can be known with simple known Detected and evaluated means and thus the additional sensors of the extractor device be made available, preferably on radio technology Ways. This signal is therefore available for the duration of the connection of the hotplate available and is registered by the additional sensors of the extractor device and fed to the control circuit. The absence of this signal causes the additional sensors, the automatic function of the extractor device out of operation enforce. In this case it is provided that the extractor device is manually operated can be set to desired performance values.
Nach einer bevorzugten Ausgestaltung ist die erfindungsgemäße Dunstabzugsvorrichtung dadurch gekennzeichnet, daß deren Steuerschaltung derart funktionstechnisch konfiguriert ist, daß bei von der zusätzlichen Sensorik erfaßbarem Kriterium einer Kochbereichs-Anschaltung für deren Dauer die Beleuchtungseinrichtung der Dunstabzugsvorrichtung aktiviert ist. Beleuchtungseinrichtungen sind übliche Bestandteile von Dunstabzugsvorrichtungen - sowohl in Hauben- als auch in Essenform. Die bevorzugte Ausgestaltung führt dazu, daß als Bedienungskomfort bei Anschaltung der Kochplatte gleichzeitig die Beleuchtung eingeschaltet wird und ist; sie dient als Sicherheitsmaßnahme aber auch dazu, weithin erkennbar darauf hinzuweisen, daß die Kochstelle beabsichtigt oder aber auch unbeabsichtigt noch angeschaltet ist.According to a preferred embodiment, the extractor device according to the invention is characterized in that the control circuit configured in such a functional way is that with a criterion of a cooking zone connection that can be detected by the additional sensors for the duration of the lighting device of the extractor device is activated. Lighting devices are common components of extractor hoods - both in hood and in food form. The preferred embodiment leads to ease of use when switching on the hotplate at the same time the lighting is on and is on; however, it serves as a security measure also to indicate clearly that the hotplate is intended or but is also switched on unintentionally.
Nach einer anderen bevorzugten Ausgestaltung ist die erfindungsgemäße Dunstabzugsvorrichtung dadurch gekennzeichnet, daß deren Steuerschaltung Handeingabeorgane z. B. in Form Tastenschaltern, Schiebeschaltern, Touch-Sensitiv-Schaltem oder ähnlichen, zugeordnet sind, über die der Automatikbetrieb und/oder die Beleuchtungseinrichtung manuell beeinflußbar sind und/oder Daueran- oder -ausschaltungen von Funktionen durchführbar sind, und zwar bevorzugt auch über die Dauer der Kochbereichs-Anschaltung hinaus. According to another preferred embodiment, the extractor device according to the invention is characterized in that the control circuit manual input members z. B. in the form of key switches, slide switches, touch-sensitive switches or the like, are assigned, via which the automatic mode and / or the lighting device can be influenced manually and / or permanent switching on or off of functions are feasible, and preferably also over the duration of the cooking area connection out.
Es kann nicht immer davon ausgegangen werden, daß die Dunstabzugsvorrichtung über einer Kochstelle angeordnet ist, die ein auswertbares Signal für die zusätzliche Sensorik abgibt. Es können auch Umstände auftreten, die die Abgabe eines entsprechenden Signals zeitweilig oder aber auch auf Dauer unterbinden.It can not always be assumed that the extractor device over a hotplate is arranged which has an evaluable signal for the additional sensor system emits. Circumstances may also arise that result in the issuance of a corresponding signal prevent it temporarily or permanently.
Um die erfindungsgemäß ausgestattete Dunstabzugsvorrichtung auch für diese Umstände nicht in ihren Grundfunktionen ausfallen zu lassen, ist nach einer Weiterbildung die erfindungsgemäßen Dunstabzugsvorrichtung dahingehend ausgestattet, daß deren Steuerschaltung derart funktionstechnisch konfiguriert ist, daß nach Einsetzen einer Spannungsversorgung die Dunstabzugsvorrichtung bis zum erstmaligen Empfang eines Kriteriums für eine Kochbereichs-Anschaltung Dauerfunktionen und Automatikbetrieb durch Eingabetasten manuell ein- und ausschaltbar sind. Dies bedeutet, daß eine Dunstabzugsvorrichtung, die zwar nach den erfindungsgemäßen Merkmalen ausgestattet ist, ursprünglich wie eine Dunstabzugsvorrichtung ohne diese Funktionsmaßnahmen betrieben werden kann. Erst wenn erstmals der Empfang eines Kriteriums für die Kochbereichs-Anschaltung durch die zusätzliche Sensorik detektiert wurde, wird die Steuerschaltung dahingehend beeinflußt, daß Automatikbetrieb sich bei diesem Kriterium für Kochbereichsanschaltung einstellt und zwar bevorzugt ausschließlich iterierend. Führt eine später auftretende Fehlerquelle zum Ausbleiben dieses Signals, kann die Ausgangssitutation für den Handbetätigungsbetrieb dadurch wiederhergestellt werden, daß die Stromversorgung kurz unterbrochen wird und damit eine erstmalige Anschaltung simuliert wird.To the extractor device equipped according to the invention also for these circumstances not to fail in their basic functions is after further training the extractor device according to the invention equipped so that their Control circuit is configured such that after inserting a Power supply the extractor device until the first reception of a Criterion for a cooking zone connection permanent functions and automatic mode can be switched on and off manually using the input keys. This means that an extractor hood, which is equipped according to the features of the invention, originally operated as an extractor hood without these functional measures can be. Only when the reception of a criterion for switching on the cooking area first was detected by the additional sensors, the control circuit influenced in that automatic mode with this criterion for Setting the cooking zone connection and preferably only iterating. Leads A later source of error for the absence of this signal can be the initial situation for manual operation can be restored in that the Power supply is interrupted briefly and thus simulates an initial connection becomes.
Nach einer anderen Weiterbildung der Erfindung ist für diesen Zusammenhang die erfindungsgemäße Dunstabzugsvorrichtung dadurch gekennzeichnet, daß die Steuerschaltung funktionstechnisch derart konfiguriert und mit einem Zeitglied ausgestattet ist, welches mit dem zusätzlichen Sensor gekoppelt ist, daß bei Ausbleiben eines Kriteriums einer Kochbereichs-Anschaltung bis zu einem erneuten Empfang dieses Kriteriums für Kochbereichs-Anschaltung Dauerfunktionen und Automatikbetrieb durch Eingabetasten manuell ein- und ausschaltbar sind.According to another development of the invention, the invention is for this connection Extractor hood device characterized in that the control circuit Functionally configured and equipped with a timer that is coupled to the additional sensor that if one criterion is absent, a Cooking area activation until this criterion is received again Cooking area connection permanent functions and automatic operation by means of input keys can be switched on and off manually.
