Definitions

  • a filter element in the form of a filter cassette can be introduced into a suction opening of the extractor hood.
  • a baffle plate can also be attached in the flow direction in front of the suction opening.
  • actuation connecting pins are moved into and out of the surface element, which engage in corresponding fastening openings on the extractor hood.
  • a handle is for example in the DE 10 2013 212 921 A1 described.
  • a disadvantage of such handles is that the surface of the surface element is interrupted by this.
  • the handle is on the side of the surface element, which is flowed towards. This leads to contamination of the handle, which makes handling, in particular removal of the surface element, difficult.
  • the object of the present invention is to provide a solution by means of which these disadvantages can at least be reduced and preferably eliminated.
  • the object is achieved by a fastening device for a surface element which is pivotally mounted on an extractor hood.
  • the fastening device is characterized in that the fastening device is a housing, a sliding element that is slidably mounted in the housing and can extend at least temporarily with respect to the housing, a push-push element via which the sliding element is at least temporarily fixed to the housing, and has a magnet which at least temporarily abuts the sliding element.
  • a surface element is an element of the extractor hood that forms at least part of the outside of the extractor hood.
  • the surface element can be a facing element, such as a part of the chimney of the extractor hood or a functional element, such as a Show filter element.
  • the surface element pivotably mounted on the extractor hood can thus represent, for example, a plate or a filter cassette.
  • the surface element is pivotally mounted on the extractor hood, in particular on an extractor housing. This mounting can take place via a joint which can be formed, for example, from holding tabs which protrude beyond the surface element on one side and openings on the extractor hood, in which the holding tabs engage.
  • a fastening device is a device by means of which the surface element is held on the extractor hood and by means of which the surface element can be detached from the extractor hood.
  • the attachment is therefore a releasable attachment.
  • the fastening device preferably acts together with the joint for holding the surface element on the extractor hood.
  • the fastening device has a housing, a sliding element, a push-push element and a magnet.
  • the housing is open on at least one side.
  • the housing can have a box shape, for example, and can be open on two opposite sides.
  • the sliding element is slidably mounted in the housing.
  • the sliding element is mounted in such a way that it can at least temporarily extend relative to the housing.
  • the sliding element in one position protrudes at least partially through an opening in the housing. Moving the sliding element represents a linear movement of the sliding element.
  • a push-push element is understood to be a displaceable element that can be brought into a locked state by applying a compressive force and by releasing a compressive force in the same direction into a released state.
  • the push-push element can be moved, for example, via a push-push mechanism that has a control link, which can also be referred to as a push-push control curve.
  • a control pin is guided in this control link.
  • the control link preferably represents a heart curve backdrop.
  • the sliding element is at least temporarily fixed to the housing of the fastening device.
  • the magnet of the fastening device is at least temporarily on the sliding element.
  • the surface element is finally attached to the extractor hood using the magnet.
  • the surface element is preferably already pre-fixed to the extractor hood by the joint via which the pivotable connection to the extractor hood exists.
  • the surface element is thus held by magnetic force on the fastening device and thus on the extractor hood.
  • the magnetic connection with the pivotably mounted surface element can be canceled.
  • the sliding element is extended or retracted by actuating the push-push element.
  • connection and thus the fastening of the surface element to the extractor hood are not brought about by mechanical means.
  • the provision of extendable pins on the surface element, which are necessary in the prior art, is not necessary.
  • the surface element can be attached to the extractor hood and the surface element can be detached from the extractor hood by simply applying a compressive force to the surface element. As a result, the push-push mechanism of the push-push element is actuated.
  • the provision of a handle on the side of the surface element facing the user, as is required in the prior art, is not necessary in the invention. This can simplify the handling of the surface element.
  • the contact area between the sliding element and the surface element decreases with increasing pivoting angle.
  • contact with the magnet also decreases and the surface element can be removed from the extractor hood, preferably after loosening the connection formed via the joint.
  • the linear displacement of the sliding element has the advantage that the manufacture of the fastening device is simplified. In particular, the manufacturing tolerances larger than with a fastening device in which an inner part must be moved by pivoting in the housing.
  • the magnet can be attached to the surface element.
  • the part of the sliding element that at least temporarily bears against the magnet consists of a magnetic material, for example of metal.
  • the magnet is also pivoted to the sliding element, that is to say it comes out of contact with the sliding element.
  • the magnetic connection between surface element and fastening element is canceled.
  • the magnetic force of the magnet is so great that, despite the external contact of the magnet and the sliding element, the surface element is still attracted to the sliding element. Only when the distance between the magnet and the sliding element is so large that the magnetic force is no longer sufficient is the magnetic connection broken.
  • the magnet is attached to the sliding element.
  • the magnet can be attached to the sliding element, for example glued on or integrated into the sliding element.
  • the magnet is provided in particular in the region of the sliding element which protrudes beyond the housing when the sliding element is moved out of the housing of the fastening device.
  • the fastening device has a locking device which limits the extension of the sliding element relative to the housing.
  • the lock can be formed, for example, by one or more projections on the sliding element, which with one or more projections on the Interact with the housing of the fastening device.
  • the projections can also be referred to as end stops. In an end position of the sliding element, in which it has been moved out of the housing of the fastening device by a predetermined amount, the projections of the sliding element are in contact with the projections of the housing and thus prevent the sliding element from extending further out of the housing.
  • the fastening device comprises a damping element for damping the displacement movement of the sliding element relative to the housing.
  • the damping element can represent a spring, for example.
  • the damping element preferably represents a rotary damper.
  • the damping element in particular dampens the extension of the sliding element. In this way, in particular when the sliding element is extended downward, an abrupt abort of the sliding movement by reaching the locking device and thereby an unwanted loosening of the magnetic connection can be prevented.
  • the damping element causes the sliding element to extend slowly, so that the sliding movement does not abruptly stop. Rather, the magnetic connection can be maintained even when the lock is reached and can be released manually by the user.
  • the push-push element has a snap-in receptacle into which a snap-in projection engages on the sliding element. This makes it possible to use a conventional push-push element, which can be connected to the sliding element via the latching connection when assembling the fastening device.
  • the invention relates to an extractor hood with an extractor housing and at least one surface element pivotably mounted on the extractor housing.
  • the extractor hood is characterized in that the extractor hood has at least one fastening device according to the invention.
  • the extractor hood housing is the part of the extractor hood to which other elements, such as facing, such as a fireplace, or functional elements, such as a vapor screen, filter elements and / or baffle plates, can be attached.
  • the extractor hood fan is accommodated in the extractor housing.
  • the fastening device is preferably attached to the extractor housing via the housing of the fastening device.
  • the housing can be introduced into an assembly opening on the extractor hood housing.
  • Locking arms which are provided on the outside of the housing, can hold the housing in the mounting opening after insertion.
  • a flange can be formed on the housing on the side in which the opening for extending the sliding element is provided, which flange extends outwards. Due to the flange and the locking arms, the housing can be held on the extractor hood housing by clamping action.
  • the fastening device is preferably fastened to the extractor hood housing in such a way that the sliding element can be extended downwards relative to the extractor hood housing.
  • the opening of the housing of the fastening device points downwards.
  • directional information relate to an extractor hood in the assembled state.
  • this information relates to an extractor hood with a suction opening that is horizontal.
  • the weight force can be used when the surface element is detached from the extractor hood.
  • the surface element is a filter element.
  • the filter element can be a filter cassette in which filter material, such as expanded metal layers, are held in a frame. Since filter elements of an extractor hood are cleaned at regular intervals from the Extractor hood must be removed, the fastening device according to the invention, which allows easy loosening is advantageous and easier to use for the user. Since, in addition to the attachment according to the invention to the surface element, apart from a holding surface or possibly a magnet, no further, in particular large-area fastening devices have to be provided, the surface of the surface element, which represents a filter element, can be used completely for filtering vapors and vapors.
