Definitions

  • the invention relates to an extractor hood with a housing having a suction opening and at least one surface element arranged in the suction opening, in particular a grease filter and / or a vapor guide plate, at least one locking device being provided for the surface element, with which the surface element on the housing in an operating position is definable.
  • Extractor hoods are used in the home in kitchens to capture the vapors generated at a hotplate and either return them to the air in a filtered way or to lead them outside into the room.
  • extractor hoods refer both to hoods that are mounted on or in an upper cabinet of a piece of kitchen furniture, and to food that is attached to a wall or to the ceiling of the room independently of the kitchen furniture.
  • Extractor hoods have a housing in which, among other things, a fan is arranged, with which the vapor is sucked in through a suction opening.
  • a grease filter and / or a vapor baffle is located in the suction opening, hereinafter referred to collectively as a surface element.
  • the task of the fat filter is to separate the fat components contained in the vapor as completely as possible.
  • the size of the grease filter corresponds to the size of the suction opening, so that all the fumes that are drawn in flow through the grease filter.
  • a vapor baffle is used in an extractor hood with edge extraction.
  • the vapor guide plate is somewhat smaller than the suction opening of the housing, so that there is a gap between the housing and the vapor guide plate, through which the vapor is sucked in.
  • a grease filter is usually located behind the vapor guide plate. It is also known to combine a vapor guide plate with a grease filter to form a common surface unit. The vapor guide plate and the grease filter form a structural unit and are assembled or disassembled together on the housing.
  • the surface element can be detached from the Housing attached.
  • a bearing point is provided which fixes the surface element relative to the housing at least in the vertical direction.
  • the bearing point usually enables a pivoting movement of the surface element relative to the housing.
  • the bearing point can comprise, for example, a hook or a hinge.
  • a locking device is usually provided with which the surface element can be locked to the housing. The locking device is spaced from a pivot axis of the surface element defined by the bearing point. In order to remove the surface element, the locking device is first released, then the surface element is pivoted downward about the pivot axis formed in the bearing point and finally the surface element is released from the housing at the bearing point.
  • Known locking devices often consist of a bolt biased into a locking position by a spring, which can be moved into an open position by an operator against the spring force.
  • the bolt is connected to a handle which is integrated in the surface element.
  • the present invention is therefore based on the object of providing an extractor hood with an ergonomically favorable locking device for the surface element, in which the risk of the surface element falling down is minimized.
  • the closure, the locking element, the guide extension and the The insertion opening are all part of the locking device.
  • the task of the guide extension and the insertion opening is to position the surface element exactly in the housing, so that the locking element is arranged exactly in front of the closure. If the surface element is pivoted downward away from the housing, the distance between the guide extension and the insertion opening is less than the distance between the latching element and the closure. When the surface element is pivoted upward, the guide extension therefore first comes into contact with the insertion opening and aligns the surface element before the latching element is inserted into the closure.
  • the at least one guide extension is arranged adjacent to the locking element.
  • Guide extension and locking element are on the same component, in close proximity to each other. Nevertheless, the guide extension and the locking element are each formed by their own bodies, which protrude from a common base plate.
  • the latching element and the at least one guide extension are arranged on the surface element. It follows from this that the closure is arranged on the housing. The insertion opening is also located on the housing, in the immediate vicinity of the closure.
  • the locking device is particularly advantageously designed as a push-push element.
  • Such locking elements are referred to as push-push elements, which are locked in a certain direction when they are first pressed and are released in the same direction when they are pressed again.
  • the surface element this means that the surface element is pressed in the direction of the housing in order to lock the surface element. Pressing the surface element again in the direction of the housing unlocks the locking element, so that the surface element can be moved downward.
  • the surface element is particularly preferably pivotally mounted on the housing about a pivot axis.
  • the surface element can be pivoted downward about the pivot axis from the operating position. This happens, for example, when the surface element is to be separated from the housing or in order to make the interior of the housing of the extractor hood accessible.
  • a bearing point for the surface element is provided, in which the pivot axis is defined.
  • the surface element is held pivotably about the pivot axis in the bearing point.
  • the bearing point is designed such that the surface element can be detached from the bearing point and thus completely removed from the extractor hood.
  • the bearing point can limit a possible swiveling movement of the surface element downwards in order to prevent an uncontrolled swiveling downwards of the surface element.
  • the bearing point ensures that the surface element does not unintentionally detach from the bearing point, which in particular prevents the surface element from falling down.
  • the torques to be absorbed by the locking device and the bearing point can be minimized by arranging the locking device at a distance from the bearing point.
  • the at least one guide extension has at least one first insertion bevel with which an offset of the latching element relative to the closure can be compensated for in a first direction, in particular in the direction perpendicular to the pivot axis.
  • the task of the insertion bevel is to enable insertion of the guide extension into the insertion opening despite an offset of the surface element.
  • the insertion slope causes the surface element to be aligned. This alignment process is completed before the locking element comes into contact with the closure.
  • the guide extension has at least a second insertion bevel with which an offset of the latching element relative to the closure in a second direction, in particular in the direction parallel to the pivot axis, can be compensated.
  • the two insertion bevels are at the same height on the guide extension, so that the surface element is aligned simultaneously in the first direction and in the second direction during a swiveling movement upwards.
  • the latching element and the guide extension are particularly advantageously formed by a common component, which is preferably made of plastic or aluminum.
  • the latching element and the at least one guide extension project separately from one another from a common base.
  • the design made of plastic or aluminum enables particularly simple production, for example as an injection or die-cast part.
  • the closure and the insertion opening are formed by separate components, which are preferably connected to one another.
  • This design makes it possible to use a standardized purchased part as a closure, while the insertion opening is provided in a housing part of the extractor hood.
  • a connection of the components of the insertion opening and the closure ensures that the insertion opening and closure are positioned exactly relative to one another.
  • the closure is essentially made of plastic.
  • the insertion opening is essentially made of metal, preferably of sheet metal.
  • FIG 1 is a perspective view of an extractor hood 1 designed as a chimney.
  • the extractor hood 1 comprises a housing 3, the underside of which has a large suction opening in which two surface elements 2 are arranged.
  • the surface elements 2 are each formed by a vapor guide plate, which is combined with a grease filter arranged on the back of the vapor guide plate. The vapor is sucked in through openings on the edge of the vapor baffle and then flows through the grease filter.
  • Vapor guide plate and grease filter form a structural unit, which is referred to here as surface element 2.
  • a chimney 4 is arranged on the top of the housing 3, in which there is a fan and channels for discharging the filtered vapors.
  • lighting elements 5 Integrated into the housing 3 are lighting elements 5, by means of which a hotplate located below the extractor hood 1 can be illuminated.
  • the present patent application relates to the type of fastening and mounting of the surface elements 2 on the housing 3. Because of the high weight of the surface element 2 constructed from a vapor baffle and a grease filter, special requirements must be placed on its mounting and mounting.
  • FIG. 2 the housing 3 is shown with only one surface element 2.
  • the second surface element is omitted in the figure, so that the interior of the housing is partially visible.
  • the suction openings 6 which run around the edge and through which the vapors rising from a hotplate are sucked in can be seen in the present illustration.
  • each surface element 2 being held with its two rear corners in a bearing point 7.
  • the front of each surface element 2 is fastened to the housing 3 with a locking device 8 in each case.
  • the locking devices 8 are designed as push-push elements.
  • the locking device 8 is released in that the surface element 2 is pressed upward in the area of the locking device 8.
  • the surface element 2 can then be pivoted downwards, the pivot axis of the surface element 2 being in the region of the bearing points 7 and being defined by them.
  • the surface element 2 is pushed up again in the area of the locking device 8.
  • the surface element 2 is locked in the housing 3.
  • the locking device 8 is unlocked and the surface element 2 is pivoted down to an end position.
  • the bearing point 7 is designed in such a way that it enables a pivoting movement of the surface element 2 about a pivot axis formed in the bearing point 7.
  • the bearing point 7 defines an end position for the pivoting movement of the surface element 2 downwards. This prevents the surface element 2 from swinging down in an uncontrolled manner after it has been unlocked by an operator and then released.
  • the bearing point 7 is designed in such a way that the surface element 2 located in the end position is fixed to the housing 3 in such a way that the surface element 2 is prevented from falling down after it has been released by the operator. In order to remove the surface element 2 from the bearing point 7, it rather has to be pivoted slightly upwards by the operator before it can be removed substantially to the front.
  • Figure 4 shows the locking device 8 with the surface element 2 slightly open.
  • a locking element 17 and two guide extensions 18 can be seen, all of which are fastened to the surface element 2.
  • a closure 16 and a guide component 20 are arranged on the housing 3 of the extractor hood 1.
  • the guide component 20 is part of the housing 3 of the extractor hood 1 and defines an insertion opening 19 for each guide extension 18.
  • Figure 5 shows in detail the elements of the locking device 8 fastened to the surface element 2.
  • the latching element 17 and the two guide extensions 18 are designed as a common component, in the present exemplary embodiment as a plastic injection-molded part.
  • the locking element 17 protrudes upward from the surface element 2 and is angled at the upper end.
  • the two guide extensions 18 are higher than the locking element 17. They each have two first insertion bevels 21 and a second insertion bevel 22 at their upper end.
  • the first insertion bevels serve to center the surface element 2 in direction A, while the second insertion bevels 22 serve to center the surface element 2 in direction B.
  • Figure 6 shows a section of the housing 3, in which the elements of the locking device 8 fastened to the housing 3 are located.
  • the closure 16 contains the mechanism of the push-push function. This push-push function has the effect that after it has been inserted into an insertion opening 23 of the closure 16, the latching element 17 is initially locked there. If the locking element 17 is then pressed again in the direction of the closure 16, it is released again and can be removed again from the insertion opening 23.
  • the structure and the exact functioning of a suitable closure 16 with push-push function is in the publication US 4655489 described.
  • the correct position of the surface element is ensured by means of the insertion openings 19 which receive the guide extensions 18.
  • the position and size of the insertion openings 19 are defined by the guide component 20, which is part of the housing 3.
  • Figure 7 shows the locking device 8 in a viewing direction obliquely from above, from the inside of the housing 3.
  • the surface element 2 is in its upper end position and is in contact with the housing 3. It is particularly easy to see how the guide extensions 18 through the guide component 20 in both horizontal directions are led.
  • the guide extensions 18 protrude through the insertion openings 19 upwards.
  • the latching element 17 also projects upward through a central opening of the guide component 20 into the area where the closure 16 is normally located.
  • Figure 8 shows the arrangement according to Figure 7 including the closure 16.
