Definitions

  • the present invention relates to an extractor hood.
  • the invention thus relates to a fume hood with fume hood housing, a cover pivotably mounted on the fume hood housing to cover the suction opening of the fume hood and an actuating mechanism for moving the cover.
  • the extractor hood is characterized in that the cover is hinged to the extractor housing and the operating mechanism comprises at least one pitch cable which engages the inside of the cover and is connected to a drive unit in the extractor housing.
  • a fume hood for a kitchen is referred to as a fume hood, by means of which fumes and vapors can be extracted from a hob installed below the fume hood and optionally from a worktop in the kitchen.
  • the extractor hood has an intake opening through which the sucked-in air, in particular the fumes and vapors, can be sucked into the interior of the extractor hood.
  • the suction opening can be arranged in the underside of the extractor hood or in the front of the extractor hood.
  • the extractor hood has a cover for covering the suction opening, which can also be referred to as the suction opening.
  • the cover covers the suction opening only temporarily.
  • the extraction opening can be covered by the cover when the extractor hood is not in operation.
  • the suction opening is provided in a fume hood housing of the fume hood.
  • the extractor housing is the part of the extractor hood in which the fan, through which the air is drawn in, is accommodated.
  • the extractor housing usually has a box or duct shape. Filter elements, which are also referred to as grease filters, can be provided in the suction opening.
  • the cover is pivotably mounted on the extractor housing.
  • the cover is therefore also referred to as a flap.
  • the cover In the closed, ie folded state, the cover preferably covers the entire extraction opening of the extractor hood and only releases an edge extraction area.
  • the sucked air is preferably conducted through the cover to the suction opening, directed and/or guided.
  • the cover When the cover is open, the path to the grease filters in the suction opening is cleared.
  • the extractor hood also has an operating mechanism for moving the cover.
  • This actuating mechanism is preferably a motorized mechanism.
  • the cover is attached to the extractor hood housing via a hinge.
  • the cover can be pivoted by this hinge.
  • damping means can be used in the hinge or separately.
  • the operating mechanism comprises at least one riser cable.
  • a cable that has a core and a helix surrounding this core is referred to as a gradient cable.
  • the core preferably consists of a rope, in particular a wire rope.
  • the coil can consist of a wire, in particular spring wire.
  • the pitch cable is used to convert rotational movement into translational movement.
  • the gradient cable can transmit tensile forces or compressive forces.
  • the ascending cable has a tensile strength of at least 2,200 N.
  • the diameter of the core can be between 2mm and 8mm, for example.
  • the diameter of the material of the coil can be, for example, in the range from 1 mm to 2 mm and the coil spacing in the range between 2 mm and 3 mm. Due to the construction of a pitch cable from a core and helix, it is flexible and can also be referred to as a flexible rack.
  • the riser cable engages on the inside of the cover.
  • the inside of the cover is the side that faces the suction opening.
  • the gradient cable can be attached directly to the inside of the cover or attached to the inside of the cover via an intermediate element, for example part of a hinge, in particular a hinge strap.
  • the riser cable is connected to a drive unit of the actuating mechanism, which is arranged in the extractor hood housing.
  • the drive unit is in particular a motorized drive unit, the one rotational movement generated.
  • the connection to the drive unit can be made, for example, via a pinion that engages in the helix of the riser cable.
  • a number of advantages can be achieved by connecting the cover to the extractor housing via a hinge according to the invention and also providing at least one riser cable which is connected to the inside of the cover and a drive unit in the extractor housing.
  • the cover can be pivoted in a simple manner in such a way that it selectively opens or closes the suction opening.
  • the space requirement is reduced through the use of at least one gradient channel and a drive unit connected thereto.
  • the cover can also be made of heavy materials such as glass, since the riser cable can transfer large forces.
  • the noise generated when the cover is pivoted can be reduced by using a riser cable and a corresponding motorized drive unit.
  • the use of a pitched cable allows the drive unit to be arranged flexibly in the extractor hood, since it can also reliably transmit power when bent.
  • the riser cable engages the hinge on the cover.
  • the riser cable may engage a leaf or strap of the hinge attached to the inside of the cover.
  • the arrangement of the riser cable on the hinge is only possible because a high force can be transmitted through the riser cable. In the case of transmission means that can only transmit a lower force, these transmission means would have to act at a location on the cover that is spaced apart from the hinge in order to be able to utilize the leverage effect.
  • Another advantage of arranging the riser cable on the hinge is that the riser cable only comes into contact with the inflowing vapor over a short length when the cover is in the open state. In addition, this arrangement also minimizes the length of the riser cable, which lies unsupported between the extractor hood housing and the cover, thereby preventing the riser cable from kinking.
  • the cover is arranged on the front side of the extractor housing and the drive unit is arranged on the rear wall of the extractor housing.
  • directions such as top, bottom, front and back refer to the extractor hood when installed.
  • the front of the extractor hood and its parts is the side that faces the user.
  • the front of the mounting wall to which the extractor hood is attached faces away.
  • the rear of the extractor hood and in particular the rear of the extractor housing is usually attached to the mounting wall.
  • the intake opening can optionally lie in the vertical or be inclined forwards to the vertical.
  • the extractor hood can also be referred to as a sloping hood.
  • the drive unit is preferably arranged on the rear wall of the extractor housing.
  • the drive unit is arranged in particular on the inside of the rear wall of the extractor hood housing.
  • the drive unit is arranged on the back of the extractor housing, it is arranged in an area of the extractor housing that lies outside of the flow area in which air flows in the extractor housing to the fan arranged therein.
  • the drive unit is thus protected.
  • the connection to the cover can also be ensured with this arrangement of the drive unit by means of riser cables, since these can be bent according to the geometry of the extractor hood housing and can nevertheless exert a force directed forwards or backwards on the cover and thus open or close it can.
  • the drive unit arranged on the rear wall of the extractor housing is offset to the center of the extractor housing.
  • This arrangement of the drive unit has the advantage that the fan, which is usually arranged centrally in the extractor housing, can still be arranged centrally and the depth of the extractor housing does not have to be increased in order to arrange the drive unit.
  • the drive unit is preferably arranged offset laterally with respect to the fan. Such an arrangement is also possible when using two riser cables, since the distance between the drive unit and the cover, which has to be covered by the riser cable, does not affect the power that can be transmitted via it.
  • the at least one ascending cable is accommodated in a guide tube at least in some areas. This can support the longitudinal rigidity of the riser cable and possibly keep the riser cable in a curved shape.
  • the at least one guide tube is preferably only designed so long that it does not protrude beyond the suction opening of the extractor housing, that is to say it is preferably located in the extractor housing.
  • the operating mechanism comprises at least two riser cables connected to a common drive unit.
  • the actuating mechanism preferably comprises exactly two riser cables.
  • each of the riser cables can engage the cover at a lateral edge or adjacent to the lateral edge of the cover. By symmetrically attacking the riser cable on the cover, the cover can be prevented from tilting during the pivoting movement. Since the riser cables are also connected to a common drive unit, it is possible to ensure that the cover swings out evenly on both sides.
  • a support structure is provided on the extractor housing, via which at least the drive unit is supported. In this way, the exact positioning of the drive unit in relation to the cover and the riser cable(s) provided between them can be ensured.
  • this support structure supports at least part of the at least one riser cable. Supporting can be direct or indirect. In particular, the riser cable can be guided directly on the support structure.
  • a guide tube in which the ascending cable is routed, can be held on the support structure.
  • an anti-trap device is arranged between the cover and the incline cable. This can prevent the user's finger or objects from getting caught.
  • the protection against pinching can be realized by a spring or another elastic element.
  • the cover of the extractor hood can be made of glass, stainless steel, aluminum or plastic, for example.
  • Each of these materials can be particularly utilized to provide an advantage of the present invention. For example, by using a gradient cable, reliable opening and closing of the cover can be ensured even with the heavy material glass. For the other materials, the attachment of the hinge or the riser cables is simplified.
  • FIG 1 is a schematic, perspective plan view of the rear of an embodiment of the extractor hood 10 according to the invention.
  • the extractor hood 10 consists of one Extractor housing 7 and a cover 3, which is also referred to as a flap.
  • the extraction opening which is covered by the cover 3 is located at the front of the extractor housing 7 and is inclined forward from the vertical.
  • the cover 3 is attached to the extractor housing 7 via a hinge 6 .
  • the hinge 6 is attached to the upper edge of the extractor housing 7 and in particular to the upper edge of the extraction opening.

  • the front end of the riser cables 2 is fixed to the cover 3 .
  • the riser cables 2 are connected to the drive unit 8 in the rear area.
  • a pinion (not shown) of the drive unit 8 can engage with the helix (not shown) of the elevator cable 2 in order to move it.
  • the riser cables 2 are held in guide tubes 1 which lie on the support structure 9 along the rear wall of the extractor housing 7 . From the rear wall of the extractor housing 7, the guide tubes 1 are bent forward and extend to the front of the extractor housing 7, that is, up to the suction opening.
  • anti-trap protection elements 4 are provided between the cover 3 and the ascending cable 2 at the front end of the ascending cable 2 .
  • figure 2 is the hood 10 after figure 1 shown in side view in the state where the cover 3 is closed. In this state, the riser cables 2 protrude slightly beyond the front of the extractor housing 7 . The cover 3 is therefore not in contact with the suction opening in this embodiment, but is at a small distance from the suction opening.
  • the hood 10 after figure 1 shown in the state where the cover 3 is unfolded. In this state it can be seen that the cover 3 has been pushed forward over the riser cable 2 .
  • FIG 4 is the range hood 10 in the state of figure 3 shown in a bottom perspective view from the front.
  • a filter element possibly provided in the suction opening of the fume hood housing 7 is not shown.
  • the riser cables 2 protrude forward beyond the suction opening, in particular the front side of the extractor hood housing 7 and beyond the guide tubes 1 .
  • the front ends of the riser cables 2 are fixed to the hinge 6 .
  • the front ends of the riser cable 2 are fixed to the inside of a hinge strap 60 of the hinge 6, which in turn is fixed to the inside of the cover 3.
  • the drive unit 8 can be attached to a separate support structure 9 , which can also be referred to as a support component, or to another component of the extractor housing 7 .
  • the motorized drive unit 8, which can be fastened to the carrier part 9, has guide tubes 1, which can be geometrically adapted to the installation situation, in which the riser cables 2, which convert the rotary movement into a translational one, are guided.
  • the cover 3 (flap) is connected to the hinge 6, which itself is connected to the extractor housing 7 and the riser cables 2.
  • the Riser cable 2 can be attached to the hinge 6 or separately on the cover 3 (flap), for example with the help of an anti-trap element 4 or without anti-trap protection.
  • the cover 3 is pivoted via the hinge 6 by actuating the drive unit 8 . Damping systems (not shown) can be integrated or fastened in the hinge 6 or on the hinge 6 .
  • the present invention has a number of advantages.
