Definitions
- the invention relates to an extractor device and a method for operating an extractor device.
- extractor hoods for example, it is from the DE 10 2006 057 545 A1 known to use an extractor hood with display device. With this extractor hood, the saturation of the filter can be displayed on the display device. The degree of saturation of the filter can be recorded by adding up the operating time of the extractor hood, possibly taking into account the volume flow of the extractor hood.
- the DE 10 2005 020 321 A1 a saturation indicator for the filters of an extractor hood.
- This saturation indicator can also be used to display the saturation level of an odor filter in the cooker hood.
- the WO 03/046437 A1 discloses a service life detection device for a filter of an extractor hood.
- a filter is provided in the extractor hood, which can be an activated carbon filter, for example.
- an air cleaning device for cleaning the sucked in air can be provided in a kitchen ventilation system. Also in the kitchen ventilation system are an air moving device and a Air direction control device provided. With this device, a pressure difference for a filter of the air cleaning device can be determined via sensors, that is to say as sensor input. The need to replace the filter can be displayed to the user.
- a problem with these extractor devices is that the correct operation of the air preparation device is decisive for the safe operation of the entire extractor device, but the user generally has no or insufficient information about the state of the air preparation device.
- the invention is based on the knowledge that this object can be achieved by providing the user with information about the condition of the air treatment device in good time before a dangerous situation occurs and this condition of the air treatment device is determined taking into account the operation of the extractor hood.
- the invention therefore relates to an extractor device with the features of claim 1.
- an extractor device is preferably referred to as an extractor device, which is used in the household, in particular in a kitchen, for removing and cleaning cooking fumes.
- a device is referred to as an extractor hood which has a blower, which is also referred to as a fan, by means of which air is sucked in from the area around and in particular below the extractor hood.
- Filter elements in particular at least one grease filter element, are preferably provided in or on the extractor hood.
- the extractor device comprises at least one active air treatment device.
- the air treatment device can be arranged in the extractor hood or provided separately from it and, for example, be connected to the extractor hood via an air line in the form of a connecting pipe or channel.
- an air treatment device is a device in which at least one air treatment device is used is provided, by means of which air in the air flow that enters the air treatment device can be treated with high energy in order to remove impurities, in particular odorous substances, from the air. Due to the high energy that is generated in the air treatment device, odorous substances contained in the air stream to be treated are decomposed or react with one another or with other species.
- oxygen molecules can be decomposed and ozone can be formed, the ozone in turn being able to react as a reactive species with the odorous substances in the air stream to be treated.
- the active air treatment device according to the invention differs from known odor filters, in which odorous substances are not decomposed but only deposited.
- the extractor device comprises at least one determination unit for determining the remaining service life, which is also referred to below as the remaining service life, of at least one component of the air treatment device.
- the determination unit can be a processing, counting and / or arithmetic unit which can be integrated in the air preparation device or in the extractor hood or can be present as a separate unit.
- the determination unit can be integrated in the control unit of the air preparation device or a control of the extractor hood.
- the remaining service life of a component of the air treatment device refers to a period of time after which the correct function of the component of the air treatment device can no longer be guaranteed or is no longer possible.
- the expiry of the remaining service life is therefore determined by the time at which a limit value of at least one state of the component is reached, for example the saturation of a filter element of the air treatment device.
- the at least one component, the remaining service life of which is determined preferably represents a functional component of the air treatment device which is necessary for the function of the air treatment device, namely for the reliable and safe removal of odorous substances from an air flow.
- the odorous substances are preferably removed by decomposing odorous substances and, if appropriate, depositing reaction products of the decomposition.
- the components of the air treatment device, the remaining service life of which is determined, thus provide according to the invention represents the air treatment device of the air treatment device or the odor filter of the air treatment device.
- the end of the remaining service life represents, for example, the saturation of the filter element with odorous substances, reactive species or other impurities.
- saturation is also understood, for example, to be the state of the filter element which the filter material was consumed, in particular decomposed, by reactive species, such as ozone, and is therefore no longer available when additional ozone enters.
- the end of the remaining service life can be determined, for example, by adding impurities to electrodes in the air treatment device, due to which the functionality of the electrodes for the treatment of an air flow is not or no longer sufficient.
- the calculation of the remaining service life is preferably understood as determining the remaining service life.
- one or more current values of a parameter can be compared with a threshold value for the respective parameter.
- the threshold value can be stored in the extractor device.
- the parameter or parameters can for example provide information about a state of the component of the air treatment device.
- the parameters do not necessarily have to represent status data of the components. Rather, a time or frequency information can preferably also be understood as a parameter which in this case indirectly provides information about a state of the component of the air treatment device. Parameters can therefore be, for example, the operating time of the extractor hood or the air preparation device.
- these parameters can be linked in tables with status data of the component, such as a degree of saturation of the filter element, or assigned to them.
- the determination unit is connected to at least one component of the extractor hood in order to obtain information about an operating state of the extractor hood.
- the operating state of the extractor hood here preferably does not exclusively represent the current operating state, but can also include operating states that occurred in the past Cooker hood templates.
- the operating state of the extractor hood is understood in particular to mean the operating state of the fan of the extractor hood, which is also referred to as a blower.
- the operating state can relate to the performance, the duration of use and / or the frequency of operation of the extractor hood and in particular the fan.
- the component to which the determination unit is connected is the fan of the extractor hood or a control of the extractor hood.
- a remaining service life of at least one component of the air treatment device is determined in the extractor device according to the invention, measures can be initiated in good time which prevent a dangerous situation and / or can ensure the proper operation of the air treatment device. Since the operating state of the extractor hood is also taken into account when determining the remaining service life, the remaining service life can be determined more precisely and reliably. If, for example, only the operation or the operating time of the air treatment device itself is used to determine the remaining service life, this can lead to incorrect values. By taking into account, according to the invention, the operating state of a device that is separate from the air preparation device but is connected to it, the determination result can be improved.
- the remaining service life can be used to determine the remaining service life at a later point in time, or it can be processed for other purposes in the extractor device with further information if necessary.
- the remaining service life is preferably output to the user of the extractor device.
- the extractor device according to the invention has at least one display device for displaying the remaining operating time of the at least one component of the air treatment device.
- the display device is preferably designed in such a way that it can output both an indication of the remaining duration and an indication of the component for which the remaining duration was determined.
- the display device is preferably an optical display device, which is also referred to as a display. Alternatively or in addition, the display device can also represent an acoustic output device.
- the display device is connected to the determination device of the extractor device.
- the information to be displayed can be obtained on the display device via this connection.
- the connection between the display device and the determination device can be indirect or direct. In the case of an indirect connection, control or processing means can be interposed, for example.
- the display device can only serve to display the remaining service life of the component or the components of the air treatment device. Preferably, however, the display device also serves to display the operating states of the extractor hood or the air preparation device at the same time. The display device can thus be integrated into the display device of the extractor hood or the air preparation device.
- the position at which the display device is provided on the range hood device is not limited to a specific location.
- the display device can for example be provided on the air treatment device itself.
- the display device is provided on the extractor hood, for example on a viewing hood of the extractor hood.
- the arrangement of the display device on the extractor hood has the advantage that, especially if the air treatment device is installed further away, the user is shown the information about the remaining service life of the component or the components of the air treatment device in his application room, for example at eye level while cooking.
- the extractor device comprises a communication interface for bidirectional communication between the extractor hood and the air preparation device.
- a communication interface for bidirectional communication is referred to here as an interface via which data, information and / or signals are transmitted between the extractor hood and the air treatment device can.
- the determined remaining service life of at least one component of the air treatment device can be transmitted to the extractor hood for display on a display device on the extractor hood.
- information data or control signals can be transmitted from the extractor hood to the air treatment device. These information data or control signals can be used to determine the remaining service life of the air preparation device. For example, the operating or power level of the extractor hood fan can be transmitted via the interface and thus taken into account when determining the remaining service life.
- the communication interface can, for example, represent a bus interface or a radio interface.
- the bus interface can be, for example, an interface of a D-bus.
- the advantage of a bus interface is that further information or signals can also be exchanged between the extractor hood and the air treatment device via the bus. For example, an input by the user on an operating element of the extractor hood can be taken into account when setting the operating parameters on the air preparation device.
- the communication interface is designed as a radio interface, the advantage can be used that a physical connection between the extractor hood and the air treatment device is not required. Thus, the placement or arrangement of the air preparation device in or separately from the extractor hood can be chosen essentially freely.
- the communication interface can represent part of a control unit of the air preparation device and / or part of the control of the extractor hood. For the display of the remaining running time of one of the components of the air treatment device, the communication interface is preferably connected to the display device.
- the air treatment device comprises an air treatment device for air treatment by means of a dielectric barrier discharge, which is also referred to below as DBE.
- the air treatment device therefore has, for example, at least two electrodes arranged parallel to one another, which can be selectively applied with voltage and thereby the discharge can be generated between the electrodes.
- the determination of the remaining service life of components of the air treatment device according to the invention is of particular importance, since in the DBE, for example, ozone is generated and the escape of ozone must be reliably prevented for safety reasons.
- a plasma can be generated in a simple manner.
- the remaining service life of the air treatment device can include, for example, the remaining service life of one of the electrodes in this configuration of the air treatment device.
- the air treatment device has at least one odor filter element, which is also referred to below as a filter element.
- This odor filter element is preferably connected downstream of the air treatment device in the direction of flow.
- the odor filter element represents, for example, at least part of the housing of the air treatment device and preferably partially surrounds at least the air treatment device, which can also be referred to as a plasma source.
- non-decomposed odorous substances are deposited in such an odor filter element.
- reactive species such as ozone can be retained in the filter element.
- the extractor device according to the invention the remaining service life of the odor filter element is determined in addition or as an alternative to the remaining service life of other components of the air treatment device.
- the invention relates to a method for operating an extractor hood device with the features of claim 4.
- the operating state of the extractor hood which is used to determine the remaining service life of one component of the air treatment device, represents, according to the invention, the operating time and / or power level of the fan of the extractor hood.
- the operating time of the extractor hood can be used when determining the remaining service life of the filter element of the air treatment device or the air treatment device of the air treatment device in order to compare this with a total service life specified by the manufacturer for the respective component. According to the invention, the remaining service life can therefore be determined by comparing an operating state of the extractor hood with a predetermined value.
- the operating time of the extractor hood can be determined on the extractor hood itself or in the air treatment device by adding up individual operating times or by counting the number of switch-on processes on the extractor hood.
- the operating stage of the extractor hood can also be taken into account.
- the operating level represents the power level of the fan of the extractor hood.
- this operating level is preferably taken into account in such a way that further information such as the operating time of the air treatment device or the extractor hood is weighted. This can mean that, for example, with a high fan level of the extractor hood, an operating time of the extractor hood with a higher value than the actually recorded value is used to determine the remaining service life.
- the component of the air treatment device provides the remaining service life is determined, an odor filter element of the air treatment device or a plasma source of the air treatment device.
- the remaining service life of the filter element can differ overall from the remaining service life of the air processing device and in particular can be shorter. Since, according to the invention, the remaining service life of the filter element and, if necessary, additionally or alternatively, the air treatment device or plasma source is determined, suitable maintenance measures can be initiated at an early stage. For example, when a minimum value of the remaining service life is reached, which is preferably greater than zero, a regeneration of the filter element can be initiated.
- the remaining service life of the at least one component is displayed, particularly preferably displayed on the extractor hood.
- This enables the user of the extractor device to be informed about the remaining service life and to initiate suitable maintenance measures, such as a filter change.
- a threshold value for example a maximum saturation value of a filter element
- the display of the remaining service life gives the user sufficient time to initiate the appropriate measures in the present invention.
- the present invention can also show the user, for example, that the remaining service life is zero, that is to say has expired. This display is then preferably in the form of a warning, for example a warning tone.
- the remaining service life is preferably calculated and more preferably also registered.
- the calculation of the remaining service life preferably includes the determination of at least one current value of a parameter of the operating state of the extractor hood.
- the operating time of the extractor hood can be used as a parameter in this context.
- individual operating times of the extractor hood, in which the extractor hood was operated can be added up.
- only operating times of the extractor hood during which the air treatment device was in operation are added up.
- the current value of the operating time of the extractor hood determined in this way can then for example, can be compared with a predetermined threshold value of the operating time, which can be specified by the manufacturer for a filter element or the air treatment device. The difference then represents the remaining service life of the corresponding component of the air treatment device.
- the remaining service life determined in this way can preferably be registered in the air preparation device. If the extractor hood is used again, the operating time of the extractor hood can then be deducted from the remaining service life that has already been calculated.
- the fan level of the extractor hood can also be taken into account in the calculation. This consideration can take place when determining the values for the parameters or else when comparing the determined values with threshold values. In the latter case, for example, the threshold value can then be reduced at a higher fan level.
- a grease filter 104 is also provided on the underside of the viewing hood 100. Via this, contaminated air, which flows onto the extractor hood 10 from below and which is also referred to as vapor, is freed from solid and liquid contaminants such as fat particles.
- an odor filter 105 is also arranged downstream of the grease filter 104 and upstream of the fan 102 in the direction of flow. This can for example be an activated carbon filter.
- the odor filter 105 can also be referred to as a prefilter and, in addition to separating odorous substances, can also be used to separate particles. Alternatively, the prefilter can also only be used to separate particles, for example. The provision of a prefilter is not absolutely necessary for the present invention.
- the chimney 101 is followed by a connecting pipe 12 which connects the extractor hood 10 to a separate air preparation device 11.
- an air preparation device 11 is also shown in the chimney 101.
- These two air treatment devices 11 shown are preferably used alternatively. This means that if a separate air treatment device 11 is provided, which is only connected to the extractor hood 10 via a line or a connecting pipe 12, no further air treatment device 11 is provided in the extractor hood 10, in particular in the chimney 101, and vice versa.
- a separate air treatment device 11 is provided, which is only connected to the extractor hood 10 via a line or a connecting pipe 12
- no further air treatment device 11 is provided in the extractor hood 10, in particular in the chimney 101, and vice versa.
- the air treatment device 11 comprises a control unit 110 which, in the embodiment shown, is integrated in the air treatment device 11 but can also be present separately from it.
- a determination unit 15 is provided for determining a remaining service life of a component of the air treatment device 11.
- the determination unit 15 is integrated into the control unit 110.
- a communication interface 14 is integrated in the control unit 110, via which the air treatment device 11 can communicate with the extractor hood 10.
- the operating elements 103 on the viewing hood 100 are connected to a controller 106 of the extractor hood 10.
- the fan 102 of the extractor hood 10 is controlled and adjusted via this controller 106.
- the fan or blower stage set in this way is displayed on the display device 108.
- the operation of the extractor hood 10, in particular the duration of operation and the fan level set are preferably stored in the controller 106 of the extractor hood 10.
- the values are recorded by the recording unit 107, which is shown as part of the controller 106 in the embodiment shown, and possibly also stored in this unit 107.
- the controller 106 is also connected to the control unit 110 of the air treatment device 11 for communication via the communication interface 14.
- signals from components of the extractor hood 10, in particular the controller 106 and thereby indirectly from the fan 102 be transmitted to the control unit 110 of the air treatment device.
- information from the air treatment device 11, in particular from the control unit 110 can also be transmitted via this connection to the controller 106. This can be information about the remaining service life of one or more of the components of the air treatment device 11, for example. This information can then be passed to the display device 108 via the controller 106 and displayed there.
- FIG 3 An embodiment of the air preparation device 11 with an air treatment device 116 is shown.
- the air treatment device 11 is shown here in an exploded view so that the interior of the air treatment device 11 can be seen.
- the filter element 114 which in the installed state forms the front and top of the air treatment device 11, is shown removed.
- the air treatment device 116 which is also referred to as a plasma source, represents an air treatment device 116 that works on the principle of the dielectric barrier discharge (DBE).
- DBE dielectric barrier discharge
- two electrodes 1160, 1161 are provided in the air treatment device 116, which electrodes are aligned parallel to one another in the embodiment shown.
- a basic voltage can be applied to one of the electrodes 1160, 1161, the voltage and the frequency being set to specific values in a targeted manner and separately from one another by means of suitable setting means (not shown).
- the determination unit 15 can, for example, also be in the extractor hood 10, for example in the controller 106 be integrated.
- the communication interface 14 can optionally be omitted or is at least no longer necessary for determining the remaining service life of one of the components, such as the filter element 114 of the air treatment device 11.
- the method according to the invention can be carried out as follows.
- a maximum value specified by the manufacturer for the period of use of the odor filter element 114 in the air treatment device 11 is stored in the determination unit 15, for example.
- the operating time of the extractor hood 10 is measured, for example, by a detection unit 107, which can have a timer for this purpose. Before starting the timer, it is preferably checked whether the air treatment device 11 is also switched on. After the extractor hood 10 has been switched off or also during operation of the extractor hood 10, the operating time is stored in the detection unit 107.
- the operating level or fan level with which the extractor hood 10 is operated is stored in the detection unit 107 together with the respective operating time. After one or more operations of the extractor hood 10, the operating time, which is made up of the individual operating times of the extractor hood 10, is determined. The fan level can be taken into account when calculating the time. This operating time can then be transmitted to the determination unit 15. There the operating time is processed with the stored maximum value of the usage time of the odor filter element 114 and the remaining service life of the odor filter element 114 is determined from this. If the fan level has not yet been taken into account when calculating the operating time, it is preferably taken into account when determining the remaining service life at the latest. This remaining service life can then be transmitted via the communication interface 14 to the display device 108 and displayed there.
- account can be taken of the fact that, in particular in the case of air treatment devices that work on the basis of DBE, the operation of the air treatment device, which is also referred to as an air cleaning unit, is only allowed in certain states of the extractor device. If specified conditions are not met, the air handling device should cannot be operated.
- One criterion here is the service life, which is also referred to as the operating time, of the air treatment device.
- the service life or operating time of individual components can deviate from the service life of the air treatment device and, if exceeded, represent a critical condition.
- the service life or remaining service life of the air treatment device or of components of the air treatment device is therefore weighted, registered, calculated and displayed to the user, for example as a function of the operating level of the extractor hood.
- the service life or remaining service life can relate to the entire device or individual components such as filters.
- the display can be made by optical, acoustic or similar signals.
- One advantage of this invention is that the user is informed of the state in which the extractor device and in particular the air preparation device are. This shows the time in which maintenance, for example a filter change, is required. In addition, the user can see the remaining service life, for example depending on the operating level of the extractor hood.

According to the invention, a device is referred to as an extractor hood which has a blower, which is also referred to as a fan, by means of which air is sucked in from the area around and in particular below the extractor hood. Filter elements, in particular at least one grease filter element, are preferably provided in or on the extractor hood.
ErfindungsgemĆ¤Ć umfasst die Dunstabzugsvorrichtung zumindest eine aktive Luftaufbereitungsvorrichtung. Die Luftaufbereitungsvorrichtung kann in der Dunstabzugshaube angeordnet oder separat zu dieser vorgesehen sein und beispielsweise Ć¼ber eine Luftleitung in Form eines Verbindungsrohres oder Kanals mit der Dunstabzugshaube verbunden sein. Als Luftaufbereitungsvorrichtung wird erfindungsgemĆ¤Ć eine Vorrichtung bezeichnet, in der mindestens eine Luftbehandlungseinrichtung vorgesehen ist, mittels derer Luft in dem Luftstrom, der in die Luftaufbereitungsvorrichtung eintritt, mit hoher Energie behandelt werden kann, um Verunreinigungen, insbesondere Geruchsstoffe aus der Luft zu entfernen. Durch die hohe Energie, die in der Luftbehandlungseinrichtung erzeugt wird, werden Geruchsstoffe, die in dem zu behandelnden Luftstrom enthalten sind, zersetzt oder reagieren mit einander oder mit anderen Spezies. Beispielsweise kƶnnen SauerstoffmolekĆ¼le zersetzt und Ozon gebildet werden, wobei das Ozon wiederum als reaktive Spezies mit den Geruchsstoffen in dem zu behandelnden Luftstrom reagieren kann. Somit unterscheidet sich die erfindungsgemƤĆe aktive Luftaufbereitungsvorrichtung von bekannten Geruchsfiltern, in denen Geruchsstoffe nicht zersetzt sondern lediglich abgelagert werden.According to the invention, the extractor device comprises at least one active air treatment device. The air treatment device can be arranged in the extractor hood or provided separately from it and, for example, be connected to the extractor hood via an air line in the form of a connecting pipe or channel. According to the invention, an air treatment device is a device in which at least one air treatment device is used is provided, by means of which air in the air flow that enters the air treatment device can be treated with high energy in order to remove impurities, in particular odorous substances, from the air. Due to the high energy that is generated in the air treatment device, odorous substances contained in the air stream to be treated are decomposed or react with one another or with other species. For example, oxygen molecules can be decomposed and ozone can be formed, the ozone in turn being able to react as a reactive species with the odorous substances in the air stream to be treated. Thus, the active air treatment device according to the invention differs from known odor filters, in which odorous substances are not decomposed but only deposited.
ErfindungsgemĆ¤Ć umfasst die Dunstabzugsvorrichtung zumindest eine Bestimmungseinheit zum Bestimmen der Restlebensdauer, die im Folgenden auch als Restlaufdauer bezeichnet wird, zumindest einer Komponente der Luftaufbereitungsvorrichtung. Die Bestimmungseinheit kann eine Verarbeitungs-, ZƤhl- und/oder Recheneinheit sein, die in der Luftaufbereitungsvorrichtung oder in der Dunstabzugshaube integriert sein kann oder als separate Einheit vorliegen kann. Beispielsweise kann die Bestimmungseinheit in der Steuereinheit der Luftaufbereitungsvorrichtung oder einer Steuerung der Dunstabzugshaube integriert sein.According to the invention, the extractor device comprises at least one determination unit for determining the remaining service life, which is also referred to below as the remaining service life, of at least one component of the air treatment device. The determination unit can be a processing, counting and / or arithmetic unit which can be integrated in the air preparation device or in the extractor hood or can be present as a separate unit. For example, the determination unit can be integrated in the control unit of the air preparation device or a control of the extractor hood.
Als Restlebensdauer einer Komponente der Luftaufbereitungsvorrichtung wird im Sinne der Erfindung eine Zeitspanne bezeichnet, nach deren Ablauf eine vorschriftsgemƤĆe Funktion der Komponente der Luftaufbereitungsvorrichtung nicht mehr gewƤhrleistet werden kann oder nicht mehr mƶglich ist. Der Ablauf der Restlebensdauer wird daher durch den Zeitpunkt des Erreichens eines Grenzwertes zumindest eines Zustandes der Komponente, beispielsweise die SƤttigung eines Filterelementes der Luftaufbereitungsvorrichtung festgelegt. Die mindestens eine Komponente, deren Restlebensdauer bestimmt wird, stellt vorzugsweise eine Funktionskomponente der Luftaufbereitungsvorrichtung dar, die fĆ¼r die Funktion der Luftaufbereitungsvorrichtung, nƤmlich fĆ¼r die zuverlƤssige und sichere Entfernung von Geruchsstoffen aus einem Luftstrom notwendig ist. Die Entfernung der Geruchsstoffe erfolgt vorzugsweise durch Zersetzen von Geruchsstoffen und gegebenenfalls Ablagern von Reaktionsprodukten der Zersetzung. Die Komponenten der Luftaufbereitungsvorrichtung, deren Restlebensdauer bestimmt wird, stellen somit erfindungsgemĆ¤Ć die Luftbehandlungseinrichtung der Luftaufbereitungsvorrichtung oder den Geruchsfilter der Luftaufbereitungsvorrichtung dar. Bei einem Filterelement der Luftaufbereitungsvorrichtung stellt das Ende der Restlebensdauer beispielsweise die SƤttigung des Filterelementes mit Geruchsstoffen, reaktiven Spezies oder anderen Verunreinigungen dar. Unter SƤttigung wird hierbei beispielsweise auch der Zustand des Filterelementes verstanden, bei dem das Filtermaterial durch reaktive Spezies, wie beispielsweise Ozon verbraucht, insbesondere zersetzt, wurde und somit beim Eintreten von weiterem Ozon nicht mehr zur VerfĆ¼gung steht. Bei der Luftbehandlungseinrichtung als Komponente der Luftaufbereitungsvorrichtung, deren Restlebensdauer bestimmt wird, kann das Ende der Restlebensdauer beispielsweise durch das Zusetzen von Elektroden in der Luftbehandlungseinrichtung mit Verunreinigungen bestimmt werden, aufgrund dessen die FunktionalitƤt der Elektroden zur Behandlung eines Luftstroms nicht oder nicht mehr ausreichend gegeben ist.In the context of the invention, the remaining service life of a component of the air treatment device refers to a period of time after which the correct function of the component of the air treatment device can no longer be guaranteed or is no longer possible. The expiry of the remaining service life is therefore determined by the time at which a limit value of at least one state of the component is reached, for example the saturation of a filter element of the air treatment device. The at least one component, the remaining service life of which is determined, preferably represents a functional component of the air treatment device which is necessary for the function of the air treatment device, namely for the reliable and safe removal of odorous substances from an air flow. The odorous substances are preferably removed by decomposing odorous substances and, if appropriate, depositing reaction products of the decomposition. The components of the air treatment device, the remaining service life of which is determined, thus provide according to the invention represents the air treatment device of the air treatment device or the odor filter of the air treatment device. In the case of a filter element of the air treatment device, the end of the remaining service life represents, for example, the saturation of the filter element with odorous substances, reactive species or other impurities. Here, saturation is also understood, for example, to be the state of the filter element which the filter material was consumed, in particular decomposed, by reactive species, such as ozone, and is therefore no longer available when additional ozone enters. In the case of the air treatment device as a component of the air treatment device, the remaining service life of which is determined, the end of the remaining service life can be determined, for example, by adding impurities to electrodes in the air treatment device, due to which the functionality of the electrodes for the treatment of an air flow is not or no longer sufficient.
Als Bestimmung der Restlebensdauer wird vorzugsweise die Berechnung der Restlebensdauer verstanden. Hierzu kƶnnen ein oder mehrere aktuelle Werte eines Parameters mit einem Schwellwert fĆ¼r den jeweiligen Parameters verglichen werden. Der Schwellwert kann in der Dunstabzugsvorrichtung hinterlegt sein. Der oder die Parameter kƶnnen hierbei beispielsweise Auskunft Ć¼ber einen Zustand der Komponente der Luftaufbereitungsvorrichtung geben. Die Parameter mĆ¼ssen hierzu nicht zwingend Zustandsdaten der Komponenten darstellen. Vielmehr kann vorzugsweise auch eine Zeit- oder HƤufigkeitsangabe als Parameter verstanden werden, die in dem Fall mittelbar Auskunft Ć¼ber einen Zustand der Komponente der Luftaufbereitungsvorrichtung geben. Parameter kƶnnen daher beispielsweise die Betriebsdauer der Dunstabzugshaube oder der Luftaufbereitungsvorrichtung sein. Beispielsweise kƶnnen diese Parameter in Tabellen mit Zustandsdaten der Komponente, wie beispielsweise einem SƤttigungsgrad des Filterelementes verbunden beziehungsweise diesen zugeordnet sein.The calculation of the remaining service life is preferably understood as determining the remaining service life. For this purpose, one or more current values of a parameter can be compared with a threshold value for the respective parameter. The threshold value can be stored in the extractor device. The parameter or parameters can for example provide information about a state of the component of the air treatment device. The parameters do not necessarily have to represent status data of the components. Rather, a time or frequency information can preferably also be understood as a parameter which in this case indirectly provides information about a state of the component of the air treatment device. Parameters can therefore be, for example, the operating time of the extractor hood or the air preparation device. For example, these parameters can be linked in tables with status data of the component, such as a degree of saturation of the filter element, or assigned to them.
ErfindungsgemĆ¤Ć ist die Bestimmungseinheit mit mindestens einer Komponente der Dunstabzugshaube zum Erhalt von Informationen Ć¼ber einen Betriebszustand der Dunstabzugshaube verbunden. Der Betriebszustand der Dunstabzugshaube stellt hierbei vorzugsweise nicht ausschlieĆlich den aktuellen Betriebszustand dar, sondern kann auch BetriebszustƤnde umfassen, die in der Vergangenheit an der Dunstabzugshaube vorlagen. Als Betriebszustand der Dunstabzugshaube wird insbesondere der Betriebszustand des LĆ¼fters der Dunstabzugshaube, der auch als GeblƤse bezeichnet wird, verstanden. Hierbei kann sich der Betriebszustand auf die Leistung, die Benutzungsdauer und/oder die HƤufigkeit des Betriebes der Dunstabzugshaube und insbesondere des LĆ¼fters beziehen.According to the invention, the determination unit is connected to at least one component of the extractor hood in order to obtain information about an operating state of the extractor hood. The operating state of the extractor hood here preferably does not exclusively represent the current operating state, but can also include operating states that occurred in the past Cooker hood templates. The operating state of the extractor hood is understood in particular to mean the operating state of the fan of the extractor hood, which is also referred to as a blower. The operating state can relate to the performance, the duration of use and / or the frequency of operation of the extractor hood and in particular the fan.
Die Komponente, mit der die Bestimmungseinheit verbunden ist, ist erfindungsgemĆ¤Ć der LĆ¼fter der Dunstabzugshaube oder aber eine Steuerung der Dunstabzugshaube.According to the invention, the component to which the determination unit is connected is the fan of the extractor hood or a control of the extractor hood.
Indem bei der erfindungsgemƤĆen Dunstabzugsvorrichtung eine Restlebensdauer mindestens einer Komponente der Luftaufbereitungsvorrichtung bestimmt wird, kƶnnen rechtzeitig MaĆnahmen eingeleitet werden, die eine Gefahrensituation verhindern und/oder den ordnungsgemƤĆen Betrieb der Luftaufbereitungsvorrichtung gewƤhrleisten kƶnnen. Da zudem der Betriebszustand der Dunstabzugshaube bei der Bestimmung der Restlebensdauer berĆ¼cksichtigt wird, kann die Bestimmung der Restlebensdauer genauer und zuverlƤssiger erfolgen. Wird nƤmlich ausschlieĆlich beispielsweise der Betrieb oder die Betriebsdauer der Luftaufbereitungsvorrichtung selber zur Bestimmung der Restlebensdauer herangezogen, kann dies zu falschen Werten fĆ¼hren. Durch die erfindungsgemƤĆe BerĆ¼cksichtigung des Betriebszustandes eines GerƤtes, das zu der Luftaufbereitungsvorrichtung separat ist, aber mit dieser verbunden ist, kann das Bestimmungsergebnis verbessert werden.Since a remaining service life of at least one component of the air treatment device is determined in the extractor device according to the invention, measures can be initiated in good time which prevent a dangerous situation and / or can ensure the proper operation of the air treatment device. Since the operating state of the extractor hood is also taken into account when determining the remaining service life, the remaining service life can be determined more precisely and reliably. If, for example, only the operation or the operating time of the air treatment device itself is used to determine the remaining service life, this can lead to incorrect values. By taking into account, according to the invention, the operating state of a device that is separate from the air preparation device but is connected to it, the determination result can be improved.
Die Restlebensdauer kann bei der erfindungsgemƤĆen Dunstabzugsvorrichtung zur Bestimmung der Restlebensdauer zu einem spƤteren Zeitpunkt verwendet werden oder zu anderen Zwecken in der Dunstabzugsvorrichtung gegebenenfalls mit weiteren Angaben verarbeitet werden. ErfindungsgemĆ¤Ć wird die Restlebensdauer vorzugsweise an den Benutzer der Dunstabzugsvorrichtung ausgegeben. Zu diesem Zweck weist die Dunstabzugsvorrichtung erfindungsgemĆ¤Ć zumindest eine Anzeigevorrichtung zur Anzeige der Restlaufdauer der zumindest einen Komponente der Luftaufbereitungsvorrichtung auf. Die Anzeigevorrichtung ist vorzugsweise so ausgestaltet, dass diese sowohl eine Angabe der Restlaufdauer als auch eine Angabe der Komponente, fĆ¼r die die Restlaufdauer bestimmt wurde, ausgeben kann. Die Anzeigevorrichtung stellt vorzugsweise eine optische Anzeigevorrichtung, die auch als Display bezeichnet wird, dar. Alternativ oder zusƤtzlich kann die Anzeigevorrichtung aber auch eine akustische Ausgabevorrichtung darstellen.In the case of the extractor device according to the invention, the remaining service life can be used to determine the remaining service life at a later point in time, or it can be processed for other purposes in the extractor device with further information if necessary. According to the invention, the remaining service life is preferably output to the user of the extractor device. For this purpose, the extractor device according to the invention has at least one display device for displaying the remaining operating time of the at least one component of the air treatment device. The display device is preferably designed in such a way that it can output both an indication of the remaining duration and an indication of the component for which the remaining duration was determined. The display device is preferably an optical display device, which is also referred to as a display. Alternatively or in addition, the display device can also represent an acoustic output device.
Die Anzeigevorrichtung ist mit der Bestimmungsvorrichtung der Dunstabzugsvorrichtung verbunden. Ćber diese Verbindung kƶnnen die anzuzeigenden Informationen an der Anzeigevorrichtung erhalten werden. Die Verbindung zwischen der Anzeigevorrichtung und der Bestimmungsvorrichtung kann mittelbar oder unmittelbar sein. Bei einer mittelbaren Verbindung kƶnnen beispielsweise Steuerungs- oder Verarbeitungsmittel zwischengeschaltet sein. Die Anzeigevorrichtung kann ausschlieĆlich zur Anzeige der Restlebensdauer der Komponente oder der Komponenten der Luftaufbereitungsvorrichtung dienen. Vorzugsweise dient die Anzeigevorrichtung aber gleichzeitig auch zur Anzeige von BetriebszustƤnden der Dunstabzugshaube oder der Luftaufbereitungsvorrichtung. Die Anzeigvorrichtung kann somit in der Anzeigevorrichtung der Dunstabzugshaube oder der Luftaufbereitungsvorrichtung integriert sein.The display device is connected to the determination device of the extractor device. The information to be displayed can be obtained on the display device via this connection. The connection between the display device and the determination device can be indirect or direct. In the case of an indirect connection, control or processing means can be interposed, for example. The display device can only serve to display the remaining service life of the component or the components of the air treatment device. Preferably, however, the display device also serves to display the operating states of the extractor hood or the air preparation device at the same time. The display device can thus be integrated into the display device of the extractor hood or the air preparation device.
Die Position, an der die Anzeigevorrichtung an der Dunstabzugsvorrichtung vorgesehen ist, ist nicht auf einen bestimmten Ort beschrƤnkt. Die Anzeigevorrichtung kann beispielsweise an der Luftaufbereitungsvorrichtung selber vorgesehen sein. GemĆ¤Ć einer bevorzugten AusfĆ¼hrungsform ist die Anzeigevorrichtung aber an der Dunstabzugshaube, beispielsweise an einer Sichthaube der Dunstabzugshaube vorgesehen. Die Anordnung der Anzeigevorrichtung an der Dunstabzugshaube weist den Vorteil auf, dass insbesondere bei einer weiter entfernten Installation der Luftaufbereitungsvorrichtung der Benutzer die Informationen Ć¼ber die Restlebensdauer der Komponente oder der Komponenten der Luftaufbereitungsvorrichtung in seinem Anwendungsraum, zum Beispiel auf Augenhƶhe wƤhrend des Kochens, angezeigt wird.The position at which the display device is provided on the range hood device is not limited to a specific location. The display device can for example be provided on the air treatment device itself. According to a preferred embodiment, the display device is provided on the extractor hood, for example on a viewing hood of the extractor hood. The arrangement of the display device on the extractor hood has the advantage that, especially if the air treatment device is installed further away, the user is shown the information about the remaining service life of the component or the components of the air treatment device in his application room, for example at eye level while cooking.
GemĆ¤Ć einer AusfĆ¼hrungsform umfasst die Dunstabzugsvorrichtung eine Kommunikationsschnittstelle fĆ¼r eine bidirektionale Kommunikation zwischen der Dunstabzugshaube und der Luftaufbereitungsvorrichtung.According to one embodiment, the extractor device comprises a communication interface for bidirectional communication between the extractor hood and the air preparation device.
Als Kommunikationsschnittstelle zur bidirektionalen Kommunikation wird hierbei eine Schnittstelle bezeichnet, Ć¼ber die Daten, Informationen und/oder Signale zwischen der Dunstabzugshaube und der Luftaufbereitungsvorrichtung Ć¼bermittelt werden kƶnnen. Ćber die Kommunikationsschnittstelle kann somit beispielsweise die ermittelte Restlebensdauer mindestens einer Komponente der Luftaufbereitungsvorrichtung an die Dunstabzugshaube zum Anzeigen an einer Anzeigevorrichtung an der Dunstabzugshaube Ć¼bermittelt werden. Weiterhin kƶnnen Informationsdaten oder Steuerungssignale von der Dunstabzugshaube an die Luftaufbereitungsvorrichtung Ć¼bermittelt werden. Diese Informationsdaten oder Steuerungssignale kƶnnen zur Bestimmung der Restlebensdauer an der Luftaufbereitungsvorrichtung verwendet werden. Beispielsweise kann die Betriebs- oder Leistungsstufe des LĆ¼fters der Dunstabzugshaube Ć¼ber die Schnittstelle Ć¼bermittelt werden und damit bei der Bestimmung der Restlebensdauer berĆ¼cksichtigt werden.A communication interface for bidirectional communication is referred to here as an interface via which data, information and / or signals are transmitted between the extractor hood and the air treatment device can. Via the communication interface, for example, the determined remaining service life of at least one component of the air treatment device can be transmitted to the extractor hood for display on a display device on the extractor hood. Furthermore, information data or control signals can be transmitted from the extractor hood to the air treatment device. These information data or control signals can be used to determine the remaining service life of the air preparation device. For example, the operating or power level of the extractor hood fan can be transmitted via the interface and thus taken into account when determining the remaining service life.
Die Kommunikationsschnittstelle kann beispielsweise eine Bus-Schnittstelle oder eine Funkschnittstelle darstellen. Die Bus-Schnittstelle kann beispielsweise eine Schnittstelle eines D-Bus sein. Der Vorteil einer Bus-Schnittstelle besteht darin, dass Ć¼ber den Bus auch weitere Informationen oder Signale zwischen der Dunstabzugshaube und der Luftaufbereitungsvorrichtung ausgetauscht werden kƶnnen. So kann beispielsweise eine Eingabe des Benutzers an einem Bedienelement der Dunstabzugshaube bei der Einstellung der Betriebsparameter an der Luftaufbereitungsvorrichtung berĆ¼cksichtigt werden. Bei Ausgestaltung der Kommunikationsschnittstelle als Funkschnittstelle kann der Vorteil genutzt werden, dass eine physikalische Verbindung zwischen der Dunstabzugshaube und der Luftaufbereitungsvorrichtung nicht erforderlich ist. Somit kann die Platzierung oder Anordnung der Luftaufbereitungsvorrichtung in oder separat zu der Dunstabzugshaube im Wesentlichen frei gewƤhlt werden. Die Kommunikationsschnittstelle kann Teil einer Steuereinheit der Luftaufbereitungsvorrichtung und/oder Teil der Steuerung der Dunstabzugshaube darstellen. FĆ¼r die Anzeige der Restlaufdauer einer der Komponenten der Luftaufbereitungsvorrichtung ist die Kommunikationsschnittstelle vorzugsweise mit der Anzeigevorrichtung verbunden.The communication interface can, for example, represent a bus interface or a radio interface. The bus interface can be, for example, an interface of a D-bus. The advantage of a bus interface is that further information or signals can also be exchanged between the extractor hood and the air treatment device via the bus. For example, an input by the user on an operating element of the extractor hood can be taken into account when setting the operating parameters on the air preparation device. If the communication interface is designed as a radio interface, the advantage can be used that a physical connection between the extractor hood and the air treatment device is not required. Thus, the placement or arrangement of the air preparation device in or separately from the extractor hood can be chosen essentially freely. The communication interface can represent part of a control unit of the air preparation device and / or part of the control of the extractor hood. For the display of the remaining running time of one of the components of the air treatment device, the communication interface is preferably connected to the display device.
ErfindungsgemĆ¤Ć umfasst die Luftaufbereitungsvorrichtung eine Luftbehandlungseinrichtung fĆ¼r eine Luftbehandlung mittels dielektrischer Barriereentladung die im Folgenden auch als DBE bezeichnet wird. Die Luftbehandlungseinrichtung weist daher beispielsweise zumindest zwei parallel zueinander angeordnete Elektroden auf, die selektiv mit Spannung beaufschlagt werden kƶnnen und dadurch die Entladung zwischen den Elektroden erzeugt werden kann. Bei dieser Art der Luftbehandlungseinrichtung ist das erfindungsgemƤĆe Bestimmen der Restlaufdauer von Komponenten der Luftaufbereitungsvorrichtung von besonderer Bedeutung, da es bei der DBE beispielsweise zu Ozonerzeugung kommt und der Austritt von Ozon aus SicherheitsgrĆ¼nden zuverlƤssig verhindert werden muss. Zudem kann bei einer Luftbehandlungseinrichtung, bei der die Luftbehandlung mittels DBE erfolgt, die Erzeugung eines Plasmas auf einfache Weise erfolgen. Die Restlebensdauer der Luftbehandlungseinrichtung kann bei der erfindungsgemƤĆen Dunstabzugsvorrichtung bei dieser Ausgestaltung der Luftaufbereitungsvorrichtung beispielsweise die Restlebensdauer einer der Elektroden umfassen.According to the invention, the air treatment device comprises an air treatment device for air treatment by means of a dielectric barrier discharge, which is also referred to below as DBE. The air treatment device therefore has, for example, at least two electrodes arranged parallel to one another, which can be selectively applied with voltage and thereby the discharge can be generated between the electrodes. With this type of air handling unit the determination of the remaining service life of components of the air treatment device according to the invention is of particular importance, since in the DBE, for example, ozone is generated and the escape of ozone must be reliably prevented for safety reasons. In addition, in the case of an air treatment device in which the air is treated by means of DBE, a plasma can be generated in a simple manner. In the case of the extractor device according to the invention, the remaining service life of the air treatment device can include, for example, the remaining service life of one of the electrodes in this configuration of the air treatment device.
ErfindungsgemĆ¤Ć weist die Luftaufbereitungsvorrichtung zumindest ein Geruchsfilterelement, das im Folgenden auch als Filterelement bezeichnet wird, auf. Dieses Geruchsfilterelement ist vorzugsweise in Strƶmungsrichtung der Luftbehandlungseinrichtung nachgeschaltet. Insbesondere stellt das Geruchsfilterelement beispielsweise zumindest einen Teil des GehƤuses der Luftaufbereitungsvorrichtung dar und umgibt vorzugsweise zumindest die Luftbehandlungseinrichtung, die auch als Plasmaquelle bezeichnet werden kann, teilweise. In einem solchen Geruchsfilterelement werden zum einen nicht zersetzte Geruchsstoffe abgelagert. Zum anderen kƶnnen reaktive Spezies, wie beispielsweise Ozon in dem Filterelement zurĆ¼ckgehalten werden. Die ordnungsgemƤĆe Funktion dieses Geruchsfilterelementes ist fĆ¼r den sicheren Betrieb der Dunstabzugsvorrichtung daher von besonderer Bedeutung. Daher wird mit der erfindungsgemƤĆen Dunstabzugsvorrichtung vorzugsweise zusƤtzlich oder alternativ zur Restlaufdauer anderer Komponenten der Luftaufbereitungsvorrichtung die Restlaufdauer des Geruchsfilterelementes bestimmt.According to the invention, the air treatment device has at least one odor filter element, which is also referred to below as a filter element. This odor filter element is preferably connected downstream of the air treatment device in the direction of flow. In particular, the odor filter element represents, for example, at least part of the housing of the air treatment device and preferably partially surrounds at least the air treatment device, which can also be referred to as a plasma source. On the one hand, non-decomposed odorous substances are deposited in such an odor filter element. On the other hand, reactive species such as ozone can be retained in the filter element. The proper functioning of this odor filter element is therefore of particular importance for the safe operation of the extractor device. Therefore, with the extractor device according to the invention, the remaining service life of the odor filter element is determined in addition or as an alternative to the remaining service life of other components of the air treatment device.
GemĆ¤Ć einem weiteren Aspekt betrifft die Erfindung ein Verfahren zum Betreiben einer Dunstabzugsvorrichtung mit den Merkmalen des Anspruchs 4.According to a further aspect, the invention relates to a method for operating an extractor hood device with the features of claim 4.
Merkmale und Vorteile, die bezĆ¼glich der erfindungsgemƤĆen Dunstabzugsvorrichtung beschrieben wurden, gelten - soweit anwendbar - entsprechend fĆ¼r das erfindungsgemƤĆe Verfahren und werden daher im Folgenden gegebenenfalls nicht erneut erwƤhnt.Features and advantages that have been described with regard to the extractor device according to the invention apply accordingly - if applicable - to the method according to the invention and are therefore possibly not mentioned again below.
Der Betriebszustand der Dunstabzugshaube, der bei der Bestimmung der Restlebensdauer der einen Komponente der Luftaufbereitungsvorrichtung verwendet wird, stellt erfindungsgemĆ¤Ć die Betriebsdauer und/oder Leistungsstufe des LĆ¼fter der Dunstabzugshaube dar.The operating state of the extractor hood, which is used to determine the remaining service life of one component of the air treatment device, represents, according to the invention, the operating time and / or power level of the fan of the extractor hood.
Die Betriebsdauer der Dunstabzugshaube kann bei der Bestimmung der Restlebensdauer des Filterelementes der Luftaufbereitungsvorrichtung oder der Luftbehandlungseinrichtung der Luftaufbereitungsvorrichtung verwendet werden, um diese mit einer vom Hersteller vorgegebenen Gesamtlebensdauer fĆ¼r die jeweilige Komponente zu vergleichen. ErfindungsgemĆ¤Ć kann die Restlebensdauer daher durch Vergleich eines Betriebszustandes der Dunstabzugshaube mit einem vorgegebenen Wert bestimmt werden. Hierbei kann die Betriebsdauer der Dunstabzugshaube an der Dunstabzugshaube selber oder in der Luftaufbereitungsvorrichtung durch Aufsummieren einzelner Betriebszeiten oder durch ZƤhlen von EinschaltvorgƤngen an der Dunstabzugshaube ermittelt werden.The operating time of the extractor hood can be used when determining the remaining service life of the filter element of the air treatment device or the air treatment device of the air treatment device in order to compare this with a total service life specified by the manufacturer for the respective component. According to the invention, the remaining service life can therefore be determined by comparing an operating state of the extractor hood with a predetermined value. The operating time of the extractor hood can be determined on the extractor hood itself or in the air treatment device by adding up individual operating times or by counting the number of switch-on processes on the extractor hood.
Bei der Bestimmung der Restlebensdauer der Komponente, beispielsweise des Filterelementes der Luftaufbereitungsvorrichtung, kann auch die Betriebsstufe der Dunstabzugshaube berĆ¼cksichtigt werden. Die Betriebsstufe stellt erfindungsgemĆ¤Ć die Leistungsstufe des LĆ¼fters der Dunstabzugshaube dar. Bei der Bestimmung der Restlebensdauer wird diese Betriebsstufe vorzugsweise so berĆ¼cksichtigt, dass weitere Angaben, wie beispielsweise die Betriebsdauer der Luftaufbereitungsvorrichtung oder der Dunstabzugshaube hierdurch gewichtet werden. Dies kann bedeuten, dass beispielsweise bei einer hohen LĆ¼fterstufe der Dunstabzugshaube eine Betriebsdauer der Dunstabzugshaube mit einem hƶheren als dem tatsƤchlich erfassten Wert fĆ¼r die Bestimmung der Restlebensdauer verwendet wird. Hierdurch wird das Bestimmen der Restlebensdauer prƤziser, da bei einer hƶheren Betriebsstufe der Dunstabzugshaube beispielsweise von einem hƶheren Volumenstrom und damit von einem schnelleren Ablagern von Geruchsstoffen, reaktiven Spezies und/oder Verunreinigungen in dem Filterelement oder an der Luftbehandlungseinrichtung ausgegangen werden kann.When determining the remaining service life of the component, for example the filter element of the air treatment device, the operating stage of the extractor hood can also be taken into account. According to the invention, the operating level represents the power level of the fan of the extractor hood. When determining the remaining service life, this operating level is preferably taken into account in such a way that further information such as the operating time of the air treatment device or the extractor hood is weighted. This can mean that, for example, with a high fan level of the extractor hood, an operating time of the extractor hood with a higher value than the actually recorded value is used to determine the remaining service life. This makes the determination of the remaining service life more precise, since at a higher operating level of the extractor hood, for example, a higher volume flow and thus faster deposition of odorous substances, reactive species and / or impurities in the filter element or on the air treatment device can be assumed.
ErfindungsgemĆ¤Ć stellt die Komponente der Luftaufbereitungsvorrichtung, deren Restlebensdauer bestimmt wird, ein Geruchsfilterelement der Luftaufbereitungsvorrichtung oder eine Plasmaquelle der Luftaufbereitungsvorrichtung dar. Insbesondere die Restlebensdauer des Filterelementes kann von der Restlebensdauer der Luftaufbereitungsvorrichtung insgesamt abweichen und insbesondere kĆ¼rzer sein. Indem erfindungsgemĆ¤Ć die Restlebensdauer des Filterelementes und gegebenenfalls zusƤtzlich oder alternativ von der Luftbehandlungseinrichtung oder Plasmaquelle bestimmt wird, kƶnnen geeignete WartungsmaĆnahmen frĆ¼hzeitig eingeleitet werden. Beispielsweise kann bei dem Erreichen eines Minimalwertes der Restlebensdauer, der vorzugsweise grƶĆer Null, ist ein Regenerieren des Filterelementes initiiert werden.According to the invention, the component of the air treatment device provides the remaining service life is determined, an odor filter element of the air treatment device or a plasma source of the air treatment device. In particular, the remaining service life of the filter element can differ overall from the remaining service life of the air processing device and in particular can be shorter. Since, according to the invention, the remaining service life of the filter element and, if necessary, additionally or alternatively, the air treatment device or plasma source is determined, suitable maintenance measures can be initiated at an early stage. For example, when a minimum value of the remaining service life is reached, which is preferably greater than zero, a regeneration of the filter element can be initiated.
ErfindungsgemĆ¤Ć wird die Restlebensdauer der mindestens einen Komponente angezeigt, besonders bevorzugt an der Dunstabzugshaube angezeigt. Hierdurch kann der Benutzer der Dunstabzugsvorrichtung Ć¼ber die Restlebensdauer informiert werden und geeignete WartungsmaĆnahmen, wie beispielsweise einen Filterwechsel einleiten. Im Gegensatz zu Warnungen, die bei GerƤten ausgegeben werden, wenn ein Schwellwert, beispielsweise ein maximaler SƤttigungswert eines Filterelementes Ć¼berschritten wird, wird durch Anzeige der Restlebensdauer dem Benutzer bei der vorliegenden Erfindung ausreichend Zeit gelassen die geeigneten MaĆnahmen einzuleiten. ZusƤtzlich kann aber auch bei der vorliegenden Erfindung dem Benutzer beispielsweise angezeigt werden, dass die Restlebensdauer Null betrƤgt, das heiĆt abgelaufen ist. Diese Anzeige erfolgt dann vorzugsweise in Form einer Warnung beispielsweise eines Warntons.According to the invention, the remaining service life of the at least one component is displayed, particularly preferably displayed on the extractor hood. This enables the user of the extractor device to be informed about the remaining service life and to initiate suitable maintenance measures, such as a filter change. In contrast to warnings that are output in devices when a threshold value, for example a maximum saturation value of a filter element, is exceeded, the display of the remaining service life gives the user sufficient time to initiate the appropriate measures in the present invention. In addition, however, the present invention can also show the user, for example, that the remaining service life is zero, that is to say has expired. This display is then preferably in the form of a warning, for example a warning tone.
ErfindungsgemĆ¤Ć wird die Restlebensdauer vorzugsweise berechnet und weiter bevorzugt zusƤtzlich registriert.According to the invention, the remaining service life is preferably calculated and more preferably also registered.
Vorzugsweise umfasst die Berechnung der Restlebensdauer die Bestimmung zumindest eines aktuellen Wertes eines Parameters des Betriebszustandes der Dunstabzugshaube. Beispielsweise kann als Parameter in diesem Zusammenhang die Betriebsdauer der Dunstabzugshaube verwendet werden. Zur Bestimmung des aktuellen Wertes der Betriebsdauer kƶnnen einzelne Betriebszeiten der Dunstabzugshaube, in denen also die Dunstabzugshaube betrieben wurde, aufsummiert werden. Vorzugweise werden hierbei nur Betriebszeiten der Dunstabzugshaube aufsummiert, bei denen auch die Luftaufbereitungsvorrichtung in Betrieb war. Der so ermittelte aktuelle Wert der Betriebsdauer der Dunstabzugshaube kann dann beispielsweise mit einem vorgegebenen Schwellwert der Betriebsdauer, die fĆ¼r ein Filterelement oder die Luftbehandlungseinrichtung vom Hersteller angegeben werden kann, verglichen werden. Die Differenz stellt dann die Restlebensdauer der entsprechenden Komponente der Luftaufbereitungsvorrichtung dar.The calculation of the remaining service life preferably includes the determination of at least one current value of a parameter of the operating state of the extractor hood. For example, the operating time of the extractor hood can be used as a parameter in this context. To determine the current value of the operating time, individual operating times of the extractor hood, in which the extractor hood was operated, can be added up. Preferably, only operating times of the extractor hood during which the air treatment device was in operation are added up. The current value of the operating time of the extractor hood determined in this way can then for example, can be compared with a predetermined threshold value of the operating time, which can be specified by the manufacturer for a filter element or the air treatment device. The difference then represents the remaining service life of the corresponding component of the air treatment device.
Um die Berechnung zu vereinfachen, kann die so ermittelte Restlebensdauer vorzugsweise in der Luftaufbereitungsvorrichtung registriert werden. Bei einer weiteren Benutzung der Dunstabzugshaube kann dann die Betriebszeit der Dunstabzugshaube von der bereits berechneten Restlebensdauer abgezogen werden.In order to simplify the calculation, the remaining service life determined in this way can preferably be registered in the air preparation device. If the extractor hood is used again, the operating time of the extractor hood can then be deducted from the remaining service life that has already been calculated.
Bei der Berechnung kann, wie bereits beschrieben, auch die LĆ¼fterstufe der Dunstabzugshaube berĆ¼cksichtigt werden. Diese BerĆ¼cksichtigung kann bei der Bestimmung der Werte fĆ¼r die Parameter oder aber bei dem Vergleich der bestimmten Werte mit Schwellwerten erfolgen. Im letztgenannten Fall kann dann beispielsweise bei einer hƶheren LĆ¼fterstufe der Schwellwert herabgesetzt werden.As already described, the fan level of the extractor hood can also be taken into account in the calculation. This consideration can take place when determining the values for the parameters or else when comparing the determined values with threshold values. In the latter case, for example, the threshold value can then be reduced at a higher fan level.
Die Erfindung wird im Folgenden erneut unter Bezugnahme auf die beiliegenden Zeichnungen erlƤutert. Hierbei zeigen:

In der Sichthaube 100 ist weiterhin ein Fettfilter 104 an der Unterseite vorgesehen. Ćber diesen wird verunreinigte Luft, die die Dunstabzugshaube 10 von unten anstrƶmt und die auch als Wrasen bezeichnet wird, von festen und flĆ¼ssigen Verunreinigungen, wie beispielsweise Fettpartikeln befreit. In der dargestellten AusfĆ¼hrungsform ist zudem in Strƶmungsrichtung nach dem Fettfilter 104 und vor dem GeblƤse 102 ein Geruchsfilter 105 angeordnet. Dieser kann beispielsweise ein Aktivkohlefilter sein. Der Geruchsfilter 105 kann auch als Vorfilter bezeichnet werden und kann zusƤtzlich zum Abscheiden von Geruchsstoffen auch zum Abscheiden von Partikeln dienen. Alternativ kann der Vorfilter beispielsweise auch nur zum Abscheiden von Partikeln dienen. FĆ¼r die vorliegende Erfindung ist aber das Vorsehen eines Vorfilters nicht zwingend erforderlich.A
An den Kamin 101 schlieĆt sich bei der dargestellten AusfĆ¼hrungsform der Dunstabzugsvorrichtung 1 ein Verbindungsrohr 12 an, das die Dunstabzugshaube 10 mit einer separaten Luftaufbereitungsvorrichtung 11 verbindet.In the embodiment of the extractor device 1 shown, the
In der dargestellten AusfĆ¼hrungsform der Dunstabzugsvorrichtung 1 ist zusƤtzlich im Kamin 101 eine Luftaufbereitungsvorrichtung 11 gezeigt. Diese beiden gezeigten Luftaufbereitungsvorrichtungen 11 werden vorzugsweise alternativ verwendet. Das bedeutet, dass beim Vorsehen einer separaten Luftaufbereitungsvorrichtung 11, die mit der Dunstabzugshaube 10 nur Ć¼ber eine Leitung oder ein Verbindungsrohr 12 verbunden ist, keine weiter Luftaufbereitungsvorrichtung 11 in der Dunstabzugshaube 10, insbesondere im Kamin 101, vorgesehen ist und umgekehrt. In der weiteren Beschreibung wird auf eine Dunstabzugshaube 10 Bezug genommen, in der insbesondere in dem GehƤuse der Dunstabzugshaube 10 und besonders bevorzugt im Kamin 101 eine Luftaufbereitungsvorrichtung 11, angeordnet ist. Die folgenden AusfĆ¼hrungen gelten aber entsprechend fĆ¼r eine separate Luftaufbereitungsvorrichtung 11.In the embodiment of the extractor device 1 shown, an
Die Luftaufbereitungsvorrichtung 11 umfasst eine Steuereinheit 110, die in der dargestellten AusfĆ¼hrungsform in der Luftaufbereitungsvorrichtung 11 integriert ist aber auch getrennt dazu vorliegen kann.The

Die Bedienelemente 103 an der Sichthaube 100 sind mit einer Steuerung 106 der Dunstabzugshaube 10 verbunden. Ćber diese Steuerung 106 wird beispielsweise das GeblƤse 102 der Dunstabzugshaube 10 gesteuert und eingestellt. Die so eingestellte LĆ¼fter- oder GeblƤsestufe wird an der Anzeigevorrichtung 108 angezeigt. ZusƤtzlich werden vorzugsweise in der Steuerung 106 der Dunstabzugshaube 10 der Betrieb der Dunstabzugshaube 10, insbesondere die Dauer des Betriebes und die dabei eingestellte LĆ¼fterstufe gespeichert. Hierzu werden die Werte von der Erfassungseinheit 107, die in der dargestellten AusfĆ¼hrungsform als Teil der Steuerung 106 gezeigt ist, erfasst und gegebenenfalls auch in dieser Einheit 107 gespeichert. Weiterhin ist in der dargestellten AusfĆ¼hrungsform die Steuerung 106 auch mit der Steuereinheit 110 der Luftaufbereitungsvorrichtung 11 zur Kommunikation Ć¼ber die Kommunikationsschnittstelle 14 verbunden.The operating

Zudem kƶnnen Ć¼ber diese Verbindung auch Informationen von der Luftaufbereitungsvorrichtung 11, insbesondere von der Steuereinheit 110 an die Steuerung 106 Ć¼bertragen werden. Hierbei kann es sich beispielsweise um Angaben Ć¼ber die Restlebensdauer einer oder mehrere der Komponenten der Luftaufbereitungsvorrichtung 11 handeln.

Alternativ zu der gezeigten Anordnung der Bestimmungseinheit 15 in der Steuereinheit 110 der Luftaufbereitungsvorrichtung 11 kann die Bestimmungseinheit 15 beispielsweise auch in der Dunstabzugshaube 10, zum Beispiel in der Steuerung 106 integriert sein. In diesem Fall kann die Kommunikationsschnittstelle 14 gegebenenfalls entfallen oder ist zumindest fĆ¼r die Bestimmung der Restlebensdauer einer der Komponenten, wie beispielsweise des Filterelementes 114 der Luftaufbereitungsvorrichtung 11 nicht mehr erforderlich.As an alternative to the arrangement shown of the
Mit der dargestellten AusfĆ¼hrungsform der Dunstabzugsvorrichtung 1 kann das erfindungsgemƤĆe Verfahren wie folgt durchgefĆ¼hrt werden. In der Bestimmungseinheit 15 ist beispielsweise ein vom Hersteller vorgegebener Maximalwert fĆ¼r die Verwendungsdauer des Geruchsfilterelementes 114 in der Luftaufbereitungsvorrichtung 11 hinterlegt. Bei BetƤtigung der Dunstabzugshaube 10 wird die Betriebszeit der Dunstabzugshaube 10 beispielsweise durch eine Erfassungseinheit 107, die zu diesem Zweck einen Timer aufweisen kann, gemessen. Hierbei wird vorzugsweise vor Starten des Timers geprĆ¼ft, ob die Luftaufbereitungsvorrichtung 11 ebenfalls angeschaltet ist. Nach Abschalten der Dunstabzugshaube 10 oder auch wƤhrend des Betriebs der Dunstabzugshaube 10 wird die Betriebszeit in der Erfassungseinheit 107 gespeichert. Zudem wird in der Erfassungseinheit 107 die Betriebsstufe oder LĆ¼fterstufe, mit der die Dunstabzugshaube 10 betrieben wird, zusammen mit der jeweiligen Betriebszeit gespeichert. Nach einem oder mehreren Betrieben der Dunstabzugshaube 10 wird die Betriebsdauer, die sich aus den einzelnen Betriebszeiten der Dunstabzugshaube 10 zusammensetzt, ermittelt. Hierbei kann die LĆ¼fterstufe bei der Berechnung der Zeit berĆ¼cksichtigt werden. Diese Betriebsdauer kann dann an die Bestimmungseinheit 15 Ć¼bermittelt werden. Dort wird die Betriebsdauer mit dem hinterlegten Maximalwert der Verwendungsdauer des Geruchsfilterelementes 114 verarbeitet und daraus die Restlebensdauer des Geruchsfilterelementes 114 bestimmt. Wurde die LĆ¼fterstufe bei der Berechnung der Betriebsdauer noch nicht berĆ¼cksichtigt, wird diese vorzugsweise spƤtestens bei der Bestimmung der Restlebensdauer berĆ¼cksichtigt. Diese Restlebensdauer kann dann Ć¼ber die Kommunikationsschnittstelle 14 an die Anzeigevorrichtung 108 Ć¼bermittelt und dort angezeigt werden.With the illustrated embodiment of the extractor device 1, the method according to the invention can be carried out as follows. A maximum value specified by the manufacturer for the period of use of the
Mit der vorliegenden Erfindung kann dem Umstand Rechnung getragen werden, dass insbesondere bei Luftaufbereitungsvorrichtungen, die auf der Basis von DBE arbeiten, der Betrieb der Luftaufbereitungsvorrichtung, die auch als Luftreinigungseinheit bezeichnet wird, nur bei bestimmten ZustƤnden der Dunstabzugsvorrichtung erlaubt ist. Werden festgelegte Bedingungen nicht erfĆ¼llt, soll die Luftaufbereitungsvorrichtung nicht betrieben werden kƶnnen. Ein Kriterium ist dabei die Lebensdauer, die auch als Betriebsdauer bezeichnet wird, der Luftaufbereitungsvorrichtung. Die Lebensdauer oder Betriebsdauer einzelner Komponenten kann dabei von der Lebensdauer des der Luftaufbereitungsvorrichtung abweichen und bei Ćberschreitung einen kritischen Zustand darstellen.With the present invention, account can be taken of the fact that, in particular in the case of air treatment devices that work on the basis of DBE, the operation of the air treatment device, which is also referred to as an air cleaning unit, is only allowed in certain states of the extractor device. If specified conditions are not met, the air handling device should cannot be operated. One criterion here is the service life, which is also referred to as the operating time, of the air treatment device. The service life or operating time of individual components can deviate from the service life of the air treatment device and, if exceeded, represent a critical condition.
Im Gegensatz zu bekannten Luftaufbereitungsvorrichtungen basierend auf DBE, die in Kombination mit DunstabzĆ¼gen betrieben werden, ist bei der vorliegenden Erfindung der Ablauf beziehungsweise das Ćberschreiten der Lebensdauer der Luftaufbereitungsvorrichtung beziehungsweise einzelner Komponenten, wie beispielsweise Filter, fĆ¼r den Anwender oder Benutzer der Dunstabzugsvorrichtung ersichtlich.In contrast to known air treatment devices based on DBE, which are operated in combination with extractor hoods, in the present invention the process or the exceeding of the service life of the air treatment device or individual components, such as filters, can be seen by the user of the extractor device.
ErfindungsgemĆ¤Ć wird daher die Betriebsdauer beziehungsweise noch verfĆ¼gbare Restlebensdauer der Luftaufbereitungsvorrichtung oder von Komponenten der Luftaufbereitungsvorrichtung, beispielsweise in AbhƤngigkeit von der Betriebsstufe der Dunstabzugshaube gewichtet, registriert, berechnet und dem Anwender angezeigt. Die Betriebsdauer beziehungsweise Restlebensdauer kann dabei das GesamtgerƤt oder einzelne Komponenten wie beispielsweise Filter betreffen. Die Anzeige kann durch optische, akustische oder Ƥhnliche Signale erfolgen.According to the invention, the service life or remaining service life of the air treatment device or of components of the air treatment device is therefore weighted, registered, calculated and displayed to the user, for example as a function of the operating level of the extractor hood. The service life or remaining service life can relate to the entire device or individual components such as filters. The display can be made by optical, acoustic or similar signals.
Ein Vorteil dieser Erfindung besteht darin, dass dem Anwender mitgeteilt wird, in welchem Zustand sich ein die Dunstabzugsvorrichtung und insbesondere die Luftaufbereitungsvorrichtung befindet. So ist ersichtlich, in welcher Zeit eine Wartung, beispielsweise ein Filterwechsel, erforderlich ist. AuĆerdem kann dem Anwender die Restlebensdauer beispielsweise in AbhƤngigkeit von der Betriebsstufe des Dunstabzuges angezeigt werden.One advantage of this invention is that the user is informed of the state in which the extractor device and in particular the air preparation device are. This shows the time in which maintenance, for example a filter change, is required. In addition, the user can see the remaining service life, for example depending on the operating level of the extractor hood.
