Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • a method for heat dissipation from devices is known, in which the fact is exploited that a jet stream directed onto a vertical wall sucks a multiple of its own volume per time from its surroundings, leads and slides along the wall. This gives the particular advantage that a relatively large cooling effect can nevertheless be achieved with a relatively low compressor output for the jet.
  • the present invention applies this principle, e.g. B. in mixing operations when different streams (gases, flue gases, vapors, drippable liquids, fluids, media and the like.) Are to be brought together, for example when smoking food, when supplying air to a burner, when extracting gases from one Hob and the like
  • a pumping tool for the transport of liquid with two identical screw-shaped driving surfaces on a propeller in the shape of a cone is known (NL-C-20 573), but it has the disadvantage that only a relatively small amount of liquid from a room on a certain geodetic Height can be pumped to another room at a different height.
  • the present invention is also directed to realizing the flow pattern of a jet stream directed onto a wall differently than previously known. This is possible, for example, with a tapered propeller with outer or inner helical guide parts, blades or drive surfaces. If an air flow emerging from a nozzle occurs at a certain distance on a baffle surface perpendicular to the flow, this flow is deflected, the air moving along the baffle surface. It has now been recognized that this relatively small air flow (primary flow) from the surrounding area pulls a relatively large secondary flow, which initially does not have the direction of the flow running on the wall, but has a strong flow velocity component in the direction of the stagnation point.
  • This fact can now be used primarily for mixing media flows, but it is also suitable for depositing or removing a relatively large amount of heat on the impact surface or for extracting air from the interior of a device or room.
  • the use for extractor hoods in kitchens is also particularly important because a large amount of air and haze can be extracted with a small, relatively slow-running and low-noise propeller.
  • FIG. 1 shows a device according to the invention, which essentially consists of a conical propeller 10. This is arranged in an opening in a wall, a baffle surface 11 being provided above the opening and being at a certain distance from the wall surface.
  • Fig. 1 the flow threads are drawn, which show that essential parts of the flow is used directly on the impact point or the axis of the propeller 10.
  • the propeller 10 is shown directly in front of the impact surface 11, which is also the wall surface of a room.
  • the flow threads show how gas is drawn in from the interior and guided along the wall.
  • FIG 3 shows an application of the device according to the invention in connection with a kitchen extractor hood.
  • the propeller 10 is again arranged directly in front of the baffle 11. This is a fixed surface which is surrounded by a housing 14. At the lower end, the housing 14 is open, so that vapors and gases can enter the opening and can be discharged upwards through a chimney or a pipe. Not shown are the drive means for the propeller 10, which, however, is rotated about its axis.
  • annular interchangeable plate 13 is also attached to the baffle 11, which plate consists, for example, of an absorbent material. If the vapors or gases are then sucked in with the aid of the propeller 10, floating particles in the gas (for example fat droplets, dust and the like) are thrown onto the plate 13, so that no exhaust air filter is required, which results in a pressure loss in the flow would mean.
  • the individual partial surfaces 1, 2 and 4 can be made of plastic or thin sheet metal and can be attached to one another after appropriate shaping.
  • the driving surface 1 corresponds to the driving surface 2, but these are offset by 180 ° to one another.
  • the interconnected surfaces form opening genes 3, which are oriented approximately 45 ° to the axis, so that gas sucked in can enter through them and can be conveyed essentially axially inwards and released at the lower end (FIG. 4).
  • the main advantage of this propeller is: production by injection molding without undercut and conveyance over the entire circular area (via the holes internal flow, via the drive surfaces 2 external flow).
  • the internal motor allows the drive motor to be cooled.
  • the propellant surfaces 1 and 2 can be made with a suitable arrangement on a cone made of soft, resilient material (rubber), so that they deform in a certain way as a result of the rotation of the propeller and the centrifugal forces resulting therefrom and enable the desired air delivery. In this case, no protective grille is required for the tapered rotor.

Abstract

Installation pour le transport de gaz, de liquides et autres, à l'aide d'une hélice en principe conique (10), qui aspire le gaz ou les liquides et les fait avancer. L'hélice (10) se compose d'au moins deux tôles de guidage en forme de surfaces hélicoïdales et comportant des ouvertures dans la région de la pointe. L'hélice peut être disposée contre une surface de rebondissemnent (11).

Claims (2)
