Definitions

  • the present invention relates to an air conditioning apparatus and method for detecting a filter element in an air treatment apparatus.
  • a treatment by means of oxygen activation is used in addition to a pure filtration.
  • a type of air treatment is for example in the DE 10 2006 008265 A1 described.
  • harmful gases are generated, such as ozone.
  • ozone may not leave the device, as this would at least lead to the odor of the user, in the worst case, but even to physical discomfort.
  • Activated carbon filters are used for this purpose.
  • ozone present in the air is retained in the activated carbon.
  • the activated carbon is subject to an aging process, which requires the regular replacement of the activated carbon. The replacement should be carried out by the user with whom the device is installed.
  • a vapor extraction device which comprises a resting in the housing of the extractor device filter assembly which at least partially covers a suction opening located in the extractor device.
  • the power supply of the fan is interrupted when there is no contact between the filter assembly and the housing.
  • a switching means is provided at the suction opening, which is arranged on the contact surface between the filter arrangement and the housing.
  • the filter assembly is in particular a filter cartridge with a frame made of sheet metal.
  • activated carbon is usually provided in the form of thick mats whose strength does not permit actuation of a switching means.
  • the invention is therefore an object of the invention to provide a solution for monitoring the presence and proper installation of an activated carbon filter in an accessory for a cooker hood.
  • the present invention is based on the finding that this object can be achieved by monitoring the installation of the filter element by means of another component.
  • an air treatment device for air-conducting domestic appliance which has a housing with an air treatment space formed therein, which is at least partially limited by at least one filter element, and at least one detection element.
  • the air treatment device is characterized in that the detection element is arranged at least partially in a receiving region for the filter element and the detection element via the filter element by a cover plate, which is applied to at least a portion of the filter element operable.
  • the air-conducting domestic appliance according to the present invention is preferably a fume extraction device, in particular an extractor hood.
  • the air treatment device is an accessory to the air-conducting household appliance and is preferably arranged separately from the household appliance and only connected via air ducts with this.
  • the housing of the air treatment device therefore has at least one air inlet opening, via which air can be guided by the air-conducting domestic appliance, in particular the extractor hood, for processing into the air treatment device.
  • at least one air outlet is provided on the housing.
  • the air outlet is preferably formed by openings in at least one of the housing walls. Particularly preferably, the openings are provided in the cover plate.
  • the cover plate preferably covers the filter element as far as possible.
  • the filter element At least in the region of the air outlet, for example the apertured region of a housing wall, the filter element is provided.
  • the filter element at least partially limits the air handling space in the housing.
  • the further boundaries of the air treatment space are formed by further housing walls in which no further openings are provided except for the air inlet.
  • the air treatment is preferably carried out in the air treatment room. Alternatively, however, it is also possible for the air to be cleaned to be guided only through the air treatment space, in order then to be freed of impurities on the filter element.
  • the filter element is preferably an activated carbon filter.
  • the detection element serves to simultaneously detect the presence and the correct installation of the filter element. In the following, this is also referred to as recognition of the filter element.
  • the detection of the filter element is preferably carried out by actuating the detection element. If the filter element is not present or not installed in accordance with the regulations, contaminated air or treating agents, such as ozone, for example, such as ozone, may be released from the air treatment room into the environment. This is undesirable. Due to the detected by the detection element missing or improper installation of the filter element, a warning can be issued or other measures are introduced to the air treatment device.
  • the receiving area for the filter element is provided in the housing of the air treatment device.
  • the receiving area is preferably bounded on four sides by walls of the housing and bounded on a further side by a support element inserted into the housing.
  • the Detecting element is arranged so that it has with the components required for detecting or detecting the filter element in the direction of the receiving area.
  • an actuating element of the detection element protrudes into the receiving area.
  • an actuation of the detection element does not take place if only the filter element is inserted in the receiving area. Rather, both the presence of the filter element and the cover plate is required for actuating the detection element.
  • the cover sheet By being operable over the filter element by the cover sheet applied to at least part of the filter element, the presence or provision of both components, cover plate and filter element can be monitored with a single detection element.
  • air outlet openings are preferably provided, via which the air purified by the filter element can escape from the air treatment device. The cover plate thus forms part of the housing of the air treatment device.
  • the filter element With the present invention, it becomes possible to accommodate different conditions that the filter element can occupy in the receiving area.
  • the regulation-compliant installation of the filter element by the detection element can be reliably monitored.
  • the position or the choice of the sensitivity of the detection element in the air treatment device according to the invention can be selected so that it recognizes only a state of installation or operating state of the filter element, that is, is actuated only in this state.
  • the detection element In a further state, which can be referred to as fixing state, the detection element, however, is not actuated and appropriate measures can be initiated.
  • switching means of the prior art in which the introduction of a filter assembly into a housing automatically leads to an actuation of the switching means, a more reliable detection of the filter element is possible in the air treatment device according to the invention.
  • a state of the filter element is understood, in which this is introduced into the receiving area, the dimensions, geometry and / or Position of the filter element but not yet meet the requirements for the operation of the air treatment device.
  • the fixing state there may be a gap between one or more of the boundaries of the receiving area and the filter element.
  • the edges of the filter element are inserted into holders at the edge of the receiving area.
  • the filter element is in the fixing state on a support device in the interior of the housing. In the fixing state, the deviation from the requirements for the operation of the air treatment device by viewing the filter element is usually not visible from the outside. As a result, there is the risk that the user tries to take the air treatment plant into operation despite the non-compliant state of the filter element.
  • the filter element In the installation or operating state, however, the filter element is received in the receiving area so that it preferably rests against all boundaries of the receiving area.
  • the cover plate bears against the filter element and holds it firmly in the receiving area.
  • the filter element In the operating state, the filter element is preferably located on all sides at the boundaries of the receiving area.
  • the detection element is arranged so that it is spaced apart from the filter element with the cover plate removed.
  • the detection element is preferably mounted on the edge of the receiving area, on which the filter element is spaced in the fixing state of the edge of the receiving area.
  • this embodiment is advantageous since the filter element is not recognized in the fixing state. The distance between the detection element and the filter element is canceled when the cover plate is applied to the filter element and the filter element is thus brought into the installed state. This can lead to a displacement or deformation of the filter element, which will be explained in more detail later.
  • the detection element may be selected such that the detection element requires an actuating force that is greater than the force that is applied through the filter element with the cover plate removed the detection element is exercised.
  • the detection element is preferably a mechanical element, such as a key or a plunger.
  • the detection element can also be, for example, a pressure sensor with a correspondingly set sensitivity. The cover plate is considered as removed, if this does not rest on the filter element or is not attached according to regulations on the housing of the air treatment device.
  • the actuation force which is required by the detection element is the force which has to be applied to the detection element in order to actuate it, that is to say that it detects the filter element.
  • this force represents the switching force that must be used to overcome counter-forces, such as spring forces applied by the mechanical element.
  • the force exerted by the filter element in the receiving area with removed or removed cover plate on the detection element can be generated for example by the weight of the filter element. Also by the geometry and strength of the filter element this can exert a certain force on the detection element.
  • the actuation force is selected to be greater than the force applied by the filter element with the cover plate removed, a detection of the not yet installed in the installed filter element is reliably avoided.
  • the filter element consists of a deformable filter material and is in particular a filter mat made of activated carbon.
  • a filter material In the case of plastically and / or elastically deformable filter elements, the risk that the filter element is in the receiving area but is not installed in accordance with the regulation is particularly great.
  • the filter element in such a filter material, can be deformed and displaced by the application of a cover plate, whereby the filter element can be brought into the installed state.
  • the deformation of the filter element may be, for example, reducing the height of the mat by compressing a filter mat.
  • the length and / or width of the mat is increased and the edges can thus be pressed against the boundaries of the receiving area for the filter element.
  • the deformation of the filter element for example, the Canceling a deformation of the filter element, which has arisen before the application of the cover sheet by the action of the weight.
  • the cover plate limits the receiving area for the filter element in at least one direction.
  • the cover plate is in this case preferably releasably attached to at least one of the housing walls.
  • the cover plate on an air outlet. This may be formed by one or more openings in the cover plate.
  • the cover plate limits the receiving area for the filter element in the housing on at least one side.
  • the filter element By attaching the cover plate, the filter element is brought from the fixing state in the installed state or held in the installed state. In particular, the filter element is moved by the cover plate in the installed position. Additionally or alternatively, the filter element can be changed by attaching the cover plate in its shape. This is advantageous because the filter element is only detected when it is in the installed state and therefore only when the cover plate is provided on the housing.
  • the risk of contact of the user with electrical components in the interior of the air treatment device can be reduced or eliminated in addition to the risk of leakage of contaminated air or pollutants.
  • an intervention protection for the user will be created because access to the inside of the housing is blocked by the cover plate.
  • the receiving area is preferably formed on at least one side by a grid which is provided in the housing.
  • this embodiment ensures that air can pass from the air treatment space to the filter element in the receiving area.
  • a grid but also provides a support or bearing surface for the filter element, thereby allowing the use of a flexible filter material.
  • the dimensions of the filter element before insertion into the receiving region are in at least one direction than the dimensions of the receiving region in this direction after the application of the cover plate.
  • At least one ozone-generating component and / or at least one live element is provided in the air treatment space.
  • the present invention is of particular advantage, since these devices, the presence and the proper installation of the filter element are required to prevent escape of ozone from the air conditioning space, bypassing the filter element.
  • electrical components are used. Access to these components while they are in operation must be prevented to avoid endangering the user. The access to these electrical components and other live elements during their operation is prevented in the present invention by the forced provision of the cover plate.
  • the detection element is a switch.
  • the switch can be connected to a warning system.
  • a warning can be issued, when the air treatment device is put into operation.
  • the switch is a normally closed, the operation of which leads to switching off the warning.
  • the switch is provided in the power supply line to at least one live element and / or an ozone generating component.
  • the switch is a NO contact. Only when the switch is actuated, the live elements are supplied with power. Since the operation of the switch according to the present invention ensures that the filter element is in the installed state and the cover plate is applied, contact of the user with live components is prevented. Also, the ozone generating component is only supplied with power when the filter element is in the installed state. In this state, preferably the edges of the filter element at the boundaries of the receiving area and leakage of the ozone bypassing the filter element can thus be prevented.
  • the cover plate forms at least two sides of the housing of the air treatment device.
  • a filter element located below the cover plate in the receiving area can be reliably brought into shape and position, that is from a fixing state in an installed state and held.
  • the cover plate can act on the filter element from two sides.
  • the filter element preferably has an L-shape.
  • the use of a cover plate, which forms two sides of the housing is advantageous because it increases the size of the area over which cleaned air can be discharged from the filter.
  • the invention relates to a method for detecting a filter element in an air treatment device for an air-conducting domestic appliance, which has a housing with an air treatment space formed therein, which is at least partially limited by at least one filter element, and at least one detection element.
  • the method is characterized in that the detection element detects the filter element by means of a cover sheet applied to at least part of the filter element.
  • the application of the cover plate is recognized in the present invention in that the filter element is in an installed state, in which it was brought or held by the cover plate. Since in the present invention, the presence of a cover plate is taken into account in the detection of the filter element, it is ensured that a filter element is detected only if it is installed according to regulations in the housing. In addition, access to the interior of the housing is prevented by the cover plate.
  • the application of the cover plate, the filter element is brought from a fixing state in an installed state or kept in the installed state.
  • the connection of a voltage supply to at least one component of the air treatment device is closed.
  • ozone can be generated by one of the components.
  • the exit of the ozone is not to be feared here, since its presence and correct installation are ensured by the recognition of the filter element.
  • the presence and correct attachment of the cover plate is ensured by the detection of the filter element, as this is a prerequisite for the detection of the filter element.
  • the connection of a voltage supply to at least one component of the air treatment device is interrupted by the detection element.
  • the power supply of the ozone-generating element is interrupted. This can ensure that no ozone is generated.
  • a warning signal that can be output in the absence or faulty installation in the housing can be switched off.
  • the method according to the invention is carried out with an air treatment device according to the invention.
  • the cover avoids according to the invention, the risk that the user obtains access to live parts and the activated carbon filter avoids the threat that ozone can escape from the device.
  • the cover plate and the activated carbon filter In order to replace the activated carbon filter, the cover plate and the activated carbon filter must be removed from the air treatment device.
  • a detection element designed as a switching element in particular a push-button switch, which can be designed as a make, which closes the electrical circuit when the overall device is correctly installed and allows ozone production, it is ensured that both the cover plate and the activated carbon filter are used in the reassembly. Due to the construction and arrangement of the switch according to the invention in the housing, it is achieved that a single switching element is sufficient to cover both described safety aspects at the same time. As a result, a cost reduction is achieved thanks to the reduction in the number of components.

  • the switching element remains unconfirmed and the air treatment device can not be put into operation.
  • the activated carbon filter is installed, but not the cover plate, so also no actuation of the switch element takes place, since the activated carbon filter is not able due to its usually insufficient dimensional stability and due to the considerable required switching forces of the switching element, without the supporting shape of the Cover plate to operate the switching element. In the case of intended device assembly, however, the switching element is reliably operated.
