Definitions

  • the invention relates to a housing of an extractor hood with an air outlet gap which is formed between a first housing component and a second housing component.
  • the term extractor hood refers in the present context to all types of hoods and food, which are arranged above a cooking point and serve to extract the vapors produced at the cooking point.
  • the shape and thus the visual impression of the hood are largely determined by the housing, which also serves to accommodate filters, fans and controls.
  • the housing is a supporting component of the hood and serves to absorb and transmit forces, esp. The weight of the hood itself. It usually consists of several housing components, which are often made of sheet metal and, for example, by screwing, riveting or welding each other are connected.
  • the housing or parts of the housing also serve to guide the Luft O's Wrasenstroms within the hood.
  • air flows can be generated, which transport the vapors to the intake opening of the extractor hood.
  • Hood shield in the front region has an air outlet gap.
  • the emerging from this air outlet gap air flow is deflected due to the Coanda effect on the semi-cylindrical front edge of the hood screen so that it is directed obliquely down-and-back and presses the rising from the cooking fumes to the rear, ie away from the person standing in front of the hob.
  • the air outlet gap is formed by a slight distance between two housing components.
  • the air outlet gap along its entire length must have a constant, defined gap width. This is also necessary because of this, so that the extractor hood with the visible from the outside air outlet gap offers a visually appealing appearance.
  • the present invention is therefore based on the object to provide a housing for an extractor hood, in which a defined gap width of a gap between two housing components is ensured in a simple manner.
  • At least one spacer is provided, with which a gap width of the air outlet gap is set.
  • the spacer constitutes a separate component and is respectively directly or indirectly connected to the first housing component and to the second housing component. With the spacer, the distance between the two housing components and thus the gap width of the air gap can be set exactly during assembly of the housing.
  • the spacer has a corresponding shape.
  • the spacer may have a groove provided with a stop into which the housing part made of sheet metal is inserted. Determining the position of the spacer in the direction parallel to the gap is not absolutely necessary, since positional deviations in this direction have no influence on the gap width.
  • the air outlet gap has a constant gap width over its entire length.
  • the required number of spacers depends on the length of the gap and on the stiffness of the material of the housing components.
  • At least one of the housing components is formed by a metal sheet. For example, aluminum or stainless steel sheet may be considered.
  • the sheet has a thickness between 0.4 and 1, 2 mm, preferably between 0.6 and 1, 0 mm.
  • Sheet metal of this thickness is particularly easy to work, but is not dimensionally stable in the area of flat surfaces.
  • the housing may have a dimensionally stable core in the region of the air outlet gap.
  • the core is directly or indirectly connected to the first and / or the second housing component and defines the position and the shape of the relevant housing components.
  • the core can be designed for example as an aluminum extruded profile.
  • the first housing component is connected to the core.
  • the core thus provides exactly the shape and the position of the first housing component.
  • the spacer is arranged on the core.
  • the position and orientation of the spacers are defined by the core. Since the first housing member is fixedly connected to the core, the core also defines the relative position of the spacers to the first housing component.
  • the spacer is connected to the core by clamping.
  • the spacer has for this purpose a clamping region which is designed as a molded gap. With this gap, the spacer can be attached to a rail formed on the core.
  • the second housing component is connected to the spacer by clamping and / or detent.
  • the second housing part has a Blechabbug in one end, with which it is plugged onto an acute-angled extension of the spacer. At a corresponding angle of the Blechabbugs the second housing component clamped to the acute-angled extension of the spacer.
  • the spacer may have at least one latching lug which engages in a corresponding recess of the second housing part.
  • the spacer made of plastic, preferably made of temperature-resistant plastic. The spacer can be produced in a simple manner, for example by injection molding. A temperature resistance of the plastic to 180 0 C is required if the housing is thermally treated after installation, for example, to burn a paint job.
  • the gap width of the air outlet gap has a nominal value between 1, 5 and 3 mm. Based on this nominal value, the gap width of the air outlet gap has a tolerance of +/- 0.3 mm, preferably of +/- 0.2 mm. With the described spacers, the gap width of the air gap can be adjusted despite the deformability of the sheet metal of the housing components in this tolerance range.
  • the air outlet gap forms a slot-shaped nozzle.
  • the nozzle represents the end of a flow channel formed in the housing.
  • the nozzle tapers to an outer side of the housing.
  • FIG. 1 shows a housing according to the invention of an extractor hood
  • FIG. 2 shows a cross section through the front area of the housing
  • FIG. 1 shows a housing of an extractor hood according to the invention.
  • the housing comprises a substantially horizontal screen (1) and a fan housing (2) arranged in the middle region above the screen, which is shown with dashed lines. From the fan housing (2) upwards extends a fireplace, not shown.
  • a housing which is attached to the left side in the drawing on a wall.
  • the invention is equally applicable to the housing of so-called island food or Dreihauben that are attached to the ceiling and have no contact with a wall.
  • a dimensionally stable core (3) which extends over the entire width (b) of the screen.
  • the core (3) is designed as an aluminum extruded profile and has the required rigidity in order to determine the shape of a core (3) adjacent the first housing component (Fig. 2, Pos. 11).
  • an edge profile (4) On the sides of the screen (1) is in each case an edge profile (4), which determines the horizontal and vertical position of the core (3).
  • a plurality of spacers (5) are plugged onto the core (3) and precisely define the position of a second housing component (FIG. 2, item 12) made of sheet metal on the upper side of the screen (1).
  • FIG. 2 shows a cross section through the front region of a housing according to the invention. Shown is the core (3) to which the first housing part (11) is attached. The position and the shape of the thin housing made of the first housing part (1 1) are defined by the core (3).
  • the second housing component (12) which is also made of thin sheet metal.
  • the position of the second housing component (12) is defined by the spacers (5).
  • the spacer (5) has an acute-angled extension (5a), on which the second housing component (12) with a
  • Blechabbug (12a) is attached. As a result, the second housing component (12) on the
  • the spacer (5) has a latching lug (Fig. 3, Pos. 5b), which engages in a recess, not shown, in the lower leg of the acute-angled extension (12a).
  • the spacer (5) is clamped to the core (3). This is done by a gap (5c) integrally formed on the spacer (5), with which the spacer (5) is slipped onto a rail (3a) integrally formed on the core (3).
  • the position of the spacer (5) is defined defined relative to the core (3) and thus relative to the first housing component (1 1).
  • the position of the second housing component (12) is - as above explained - set relative to the spacer, so that the second housing member (12) also relative to the first housing member (11) has a precisely defined position.
  • the two housing components (1 1, 12) are positioned so that they are slightly spaced apart and form an air outlet gap (7).
  • the air outlet gap (7) extends at least approximately over the entire width (b) of the housing. It is arranged such that an air flow (8) exits through the air outlet gap (7) from the housing and is then deflected in a direction obliquely back / down due to the Coanda effect along the curved outer side of the first housing component.
  • the gap width (a) of the air outlet gap (7) is predetermined by the shape, the dimension and the position of the at least one spacer (5).
  • FIG. 3 shows the spacer from the arrangement according to the invention in detail.
  • the spacer (5) is made by injection molding of temperature-resistant plastic. By distributing a plurality of spacers over the entire length of the air outlet gap (7), a uniform gap width is ensured. This ensures that over the entire width of the hood a uniform air flow (8) and thus ensures optimum performance of the hood is guaranteed.
