Definitions

  • the invention relates to a fume extraction device and a method for operating a fume extraction device.
  • air purification devices For the purification of air, especially in extractor devices, which are used in kitchens, for removing and cleaning cooking fumes, it is known to use air purification devices in addition to the cleaning of the air through filters in an extractor hood, in which the air, preferably after a pre-cleaning is actively treated.
  • air treatment devices for example, devices are used with which the air to be purified is treated by means of high energies.
  • air conditioning devices also referred to as air cleaner units or air cleaners, are used in which cleaning is performed based on dielectric barrier discharge (DBE).
  • DBE dielectric barrier discharge
  • the extractor hood and air treatment device are usually separately, that is operated independently of each other.
  • a problem with these extractor devices is that the proper operation of the air treatment device for the safe operation of the entire extractor device is relevant, but the user is usually no or only insufficient information about the state of the air treatment device available.
  • the invention is based on the finding that this object can be achieved by providing the user with information about the condition of the air treatment device in good time prior to the occurrence of a dangerous situation and determining this condition of the air conditioning device taking into account the operation of the extractor hood.
  • the invention therefore relates to a fume extraction device which comprises at least one extractor hood and at least one air treatment device.
  • the extractor device is characterized in that the air treatment device constitutes an active air treatment device and the extractor device has at least one determination unit for determining the remaining service life of at least one component of the air treatment device and the determination unit is connected to at least one component of the extractor hood for obtaining information about an operating state of the extractor hood.
  • a fume extraction device As extractor device according to the invention preferably a fume extraction device is referred to, which is used in the home, especially in a kitchen for removing and cleaning cooking fumes.
  • a device As an extractor hood according to the invention a device is referred to, which is a fan, 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 fat 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 be provided separately from it and connected to the extractor hood, for example via an air line in the form of a connecting pipe or duct.
  • an air treatment device is a device in which at least one air treatment device is provided by means of which air in the air stream entering the air treatment device can be treated with high energy in order to remove impurities, in particular odorants, from the air. Due to the high energy generated in the air treatment device, odors contained in the air stream to be treated are decomposed or react with each other or with other species.
  • oxygen molecules may be decomposed and ozone formed, which in turn may react as a reactive species with the odors in the air stream to be treated.
  • the active air treatment device according to the invention differs from known odor filters, in which odors 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 Remaining running time is designated, 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 treatment device or in the extractor hood or can be present as a separate unit.
  • the determination unit may be integrated in the control unit of the air treatment device or a control of the hood.
  • the remaining life of a component of the air treatment device is referred to a period of time according to the invention, after the expiration of a proper 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, for example the saturation of a filter element of the air treatment device, is reached.
  • the at least one component, whose remaining service life 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 odors from an air stream.
  • the removal of the odorous substances is preferably carried out by decomposing odors and optionally depositing reaction products of the decomposition.
  • the components of the air treatment device whose remaining service life is determined thus preferably represent the air treatment device of the air treatment device or parts of the air treatment device and / or a filter element of the air treatment device.
  • the end of the remaining service life represents saturation of the filter element with odorous substances, reactive species or other impurities. Saturation is understood here as meaning, for example, the condition of the filter element in which the filter material is consumed by reactive species such as ozone, in particular decomposed, and thus is no longer available when further ozone enters.
  • the end of the remaining life can be determined for example by adding electrodes in the air treatment device with impurities, due to which the functionality of the electrodes for the treatment of air flow is not or no longer sufficient.
  • the determination of the remaining service life is preferably understood as the calculation of 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 one or more parameters may 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, preferably a time or frequency indication can also be understood as a parameter, which in the case indirectly provides information about a state of the component of the air treatment device. Parameters can therefore be, for example, the operating life of the extractor hood or the air treatment device.
  • these parameters may be associated in tables with state data of the component, such as a degree of saturation of the filter element or associated with it.
  • the determination unit is connected to at least one component of the extractor hood for obtaining 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 may also include operating states that were present in the past on the extractor hood.
  • the operating state of the extractor hood is understood in particular to be the operating state of the fan of the extractor hood, which is also referred to as fan.
  • the operating state can relate to the power, the duration of use and / or the frequency of operation of the extractor hood and in particular of the fan.
  • the component to which the determination unit is connected may therefore be, for example, the fan of the extractor hood or a control of the extractor hood.
  • determining a residual service life of at least one component of the air treatment device in the extractor device By determining a residual service life of at least one component of the air treatment device in the extractor device according to the invention, measures can be taken in good time to prevent a dangerous situation and / or the proper operation of the air treatment device can guarantee.
  • the determination of the remaining service life can be made more accurately and reliably. If, for example, exclusively the operation or the operating duration of the air treatment device itself is used to determine the remaining service life, this can lead to incorrect values. Due to the inventive consideration of the operating state of a device that is separate to the air treatment device, but connected to this, the determination result can be improved.
  • the remaining service life can be used in the extractor device according to the invention for determining the remaining service life at a later time or be processed for other purposes in the extractor device, optionally with further information. Additionally or alternatively, the remaining service life is preferably output to the user of the extractor device.
  • the extractor device preferably has at least one display device for indicating the remaining service life of the at least one component of the air treatment device.
  • the display device is preferably designed such that it can output both an indication of the remaining service life and an indication of the component for which the remaining service life has been determined.
  • the display device preferably represents an optical display device, which is also referred to as a display. Alternatively or additionally, however, the display device may also represent an acoustic output device.
  • the display device is preferably connected to the determining device of the extractor device. Through this connection, the information to be displayed can be obtained on the display device.
  • the connection between the display device and the determination device can be direct or indirect. In an indirect connection, for example, control or processing means may be interposed.
  • the display device can only serve to indicate the remaining service life of the component or of the components of the air treatment device. Preferably, however, the display device also serves to display operating states of the extractor hood or the air treatment device. The display device can thus be integrated in the display device of the extractor hood or the air treatment device.
  • the position at which the display device is provided on the extractor device is not limited to a specific location.
  • the display device may be provided, for example, on the air treatment device itself. According to a preferred embodiment, however, 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, in particular in a further installation of the air treatment device, the user information about the remaining life of the component or the components of the air treatment device in its application room, for example, at eye level during cooking, is displayed.
  • the extractor device comprises a communication interface for bidirectional communication between the extractor hood and the air conditioning device.
  • a communication interface for bidirectional communication in this case an interface is indicated, can be transmitted via the data, information and / or signals between the extractor hood and the air treatment device.
  • 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 via the communication interface.
  • information data or control signals can be transmitted from the hood to the air treatment device. These information data or control signals may be used to determine the remaining life of the air conditioning device. For example, the operating or performance level of the fan of the hood can be transmitted via the interface and thus taken into account in determining the remaining service life.
  • the communication interface can represent, for example, 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 over the bus also more information or signals between the hood and the air conditioning device can be replaced. Thus, for example, an input of the user to an operating element of the extractor hood can be taken into account when setting the operating parameters at the air treatment device.
  • the communication interface 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 treatment device in or separately from the extractor hood can be chosen essentially freely.
  • the communication interface may form part of a control unit of the air treatment device and / or part of the control of the hood. For the indication of the remaining service life 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 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 subjected to voltage selectively and thus the discharge between the electrodes can be generated.
  • determining the residual service life of components of the air treatment device according to the invention is of particular importance, since, for example, ozone generation occurs in the DBE and the escape of ozone must be reliably prevented for safety reasons.
  • the generation of a plasma can be carried out 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.

  • the residual running time of the odor filter element is preferably determined additionally or alternatively to the remaining running time of other components of the air treatment device with the extractor device according to the invention.
  • the invention relates to a method for operating a fume extraction device which comprises at least one extractor hood and at least one air treatment device.
  • the method is characterized in that at least one operating state of the extractor hood is used in determining the remaining service life of at least one component of the air treatment device.
  • the operating state of the extractor hood which is used in the determination of the remaining life of a component of the air treatment device, for example, represents the operating time and / or the operating level of the hood and in particular the operating time and / or power level of the fan of the hood.
  • the operating life of the extractor hood can be used in the determination of the remaining service life of, for example, the filter element of the air treatment device or the air treatment device of the air treatment device to compare this with a total specified by the manufacturer total life for the respective component.
  • 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 Extractor hood on the hood itself or in the air conditioning device by summing up individual operating times or by counting of switching on the hood are determined.
  • the operating stage of the extractor hood is taken into account.
  • the operating stage preferably represents the power or fan level of the fan of the extractor hood.
  • this operating stage is preferably taken into account so that further details, such as the operating time of the air treatment device or the extractor hood are weighted thereby. This may mean that, for example, in the case of a high fan level of the extractor hood, a service life of the extractor hood with a value greater than that actually recorded is used to determine the remaining service life.
  • the determination of the remaining service life becomes more precise, since at a higher operating level of the extractor hood, for example, a higher volume flow and thus a faster deposition of odors, reactive species and / or impurities in the filter element or at the air treatment device can be assumed.
  • the component of the air treatment device the remaining service life is determined, a filter element, in particular an odor filter element of the air treatment device and / or a plasma source of the air treatment device.
  • the remaining life of the filter element may differ from the remaining life of the air treatment device as a whole and in particular be shorter.
  • appropriate maintenance measures can be initiated early. For example, when a minimum value of the remaining service life, preferably greater than zero, is reached, a regeneration of the filter element can be initiated.
  • the remaining life of the at least one component is displayed, particularly preferably displayed on the hood.
  • the user of the extractor device can be informed about the remaining life and initiate appropriate maintenance, such as a filter change.
  • appropriate maintenance such as a filter change.

  • the user can also be shown, for example, that the remaining service life is zero, that is, has expired. This display is then preferably in the form of a warning, for example, a warning tone.
  • the remaining life is preferably calculated and further preferably additionally registered.
  • the calculation of the residual 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.
  • Preferably only operating times of the extractor hood are summed up, in which the air treatment device was in operation.
  • the thus determined current value of the operating time of the extractor hood can then be compared, for example, with a predetermined threshold value of the operating time, which can be specified for a filter element or the air treatment device by the manufacturer. The difference then represents the remaining 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 treatment device.
  • the operating time of the hood can be deducted from the already calculated remaining service life.
  • the fan level of the extractor hood can also be taken into account.
