Definitions

  • the invention relates to a fan device for an extractor hood as defined in the preamble of claim 1.
  • a fan device with the structural features of claim 1, but for an automobile, is known from US-A-5,951,245 known.
  • the fan assembly includes a cooling fan with radial impellers, which is provided with an axially directed inlet nozzle and a front cover plate of the impeller.
  • a guide ring In the inlet region and within the inlet opening of the radial impeller, a guide ring is arranged with a deflection angle of about 90 °, the front entry level terminates approximately with the plane of the cover plate of the impeller or lies in front of this.
  • the rear plane of the guide ring is arranged in the front region of the axial extent of the blade ring, resulting in a significantly lower axial depth without significantly affecting the running properties of the cooling fan.
  • an axial fan housing which consists in particular for cooling purposes in EMC-shielded devices, consisting of an air passage opening having a receiving part for an axial fan and the air passage opening covering, metallic Ablegitter.
  • the shielding grid is formed in the manner of an air guide wheel with blade-like, extending over a certain air guide length, substantially radially arranged guide webs.
  • the guide webs are arranged distributed in at least two concentric rows of circles, wherein the number of guide ribs in the outer circle row is greater than in the adjacent inner row of circles.
  • a circumferential angular spacing of the guide webs at the respective inner connection decreases starting from the innermost circle row up to the outermost circle row.
  • an inclination angle, ie an angle inclination of the guide ribs to the radial, as well as a guide angle, ie an angle inclination to the axial from the innermost circle row to the outermost circle row decrease.
  • each guide bar has an inlet side facing the top and a downstream side facing the bottom.
  • the upper sides in each case from the inflow side to the outflow side convexly curved in particular arcuately form with a radius of curvature R curved.
  • This radius of curvature is in each case selected such that a tangent applied in the region of the inflow side substantially corresponds to the respective guide angle, while a tangent applied to the opposite outflow side to the upper side corresponds essentially to the axial direction.
  • the underside of each guide bar should preferably be formed substantially flat, but it may also be provided that the underside is also provided with a concave or convex curvature.
  • the blower assembly comprises a centrifugal fan driven by an electric motor and a stationary means for selectively swirling a certain volume of air as the air enters the centrifugal blower assembly.
  • the device is arranged axially with respect to the axis of rotation of the ventilation device and is fixed in such a way that it does not move with respect to the fan.
  • the fan unit and the stationary device is surrounded by a housing, wherein the stationary device may be formed integrally with the housing.
  • the centrifugal blower arrangement has the disadvantage that the stationary device is structurally very complicated and only a low efficiency of the centrifugal fan is achieved due to the turbulence caused by the stationary device.
  • a fan with angled webs in which a network of struts and circular ribs are provided over the fan wheel.
  • the struts are angled here and have an outer part which extends in the radial direction from the outer periphery.
  • the inner part of the struts is angled relative to the outer part and blued in the plane of the outer part.
  • the cross section of the struts may have a rounded front and a back in the flow direction.
  • the circular ribs are arranged concentrically about the axis of the axial fan and connect the struts of the network.
  • the ribs While the inner ribs are axially aligned, the ribs are arranged inclined in the outer region of the network. Due to the bent or bent geometry of the struts, the edges of the blades of the fan wheel are not aligned with the course of the struts. A disadvantage of the network described is that only through the inclination of the ribs targeted guidance of the air flow is not possible.
  • a ventilator and diffuser device which comprises a first series of conically shaped vanes arranged concentrically and at a distance from one another. Furthermore, a second series of vanes or guide surfaces is provided which are cylindrical. The two rows of baffles are each firmly connected to each other, wherein the axial distance from each other via a screw spindle is variable.
  • Object of the present invention is to provide a fan device in particular for extractor hoods, which has a low noise during operation, a high air flow rate achieved with low power consumption and only a small space required.
  • the walls of the openings in the carrier part are curved in the flow direction such that the air can flow smoothly through the openings and / or smoothly overflow to the fan or that the air from the fan overflow to the openings smoothly and / or can flow out of the openings , the sucked or blown air is deflected gentler and significantly reduces the flow resistance of the openings in the support member.
  • the fan wheel is mounted on the carrier part, which has the openings in an inflow region of the fan wheel.
  • the openings are formed by a grid, which is formed by the walls having thin-walled webs, wherein the webs are curved in cross-section such that inflowing air is spatially pre-aligned and fed bumplessly to the fan or the air flowing from the fan air the openings spatially prepared and supplied bumpless, the flow resistance of the fan device can be reduced.
  • the curved webs are mechanically very stiff, so that the webs can be formed very thin-walled.
  • the flow resistance can be reduced and, on the other hand, the forces introduced by the fan can be transmitted better.
  • a motor preferably an electric motor
  • the fan wheel is mounted on an output shaft of the motor.
  • a particularly effective noise minimization and an increase in the fan power is achieved in that the curvature of the webs in the cross-sectional direction or the curvature of the walls of the openings is provided such that substantially in the axial direction of the fan to be sucked air is deflected in the direction of rotation of the fan so that it is guided by the blades of the fan in a simple manner to a Ausström Rail the fan with minimal flow resistance.
  • the walls of the openings or the webs of the grid are formed convexly or concavely in the cross-sectional direction so that air initially flowing perpendicular to the fan wheel slowly with increasing flow path in the grid and steadily in an at least approximately radial direction of the fan wheel, in the direction of rotation of the fan wheel is deflected.
  • the fan device it is provided to design the walls of the openings or the webs in the cross-sectional direction parabolic, so that initially only slightly deflected air flowing into the grid is increasingly deflected with increasing flow in the grid in the direction of rotation of the fan.
  • a very harmonious, afflicted with lower flow energy losses deflection is achieved in an advantageous manner, which additionally reduces noise and reduces the power requirement of the fan device with the same air flow.
  • Another constructional measure for the harmonious and quiet flow guidance of sucked by the fan air represents a further advantageous embodiment of the fan device, wherein a portion of the walls of the openings or a portion of the webs of the grid are at least approximately formed as a hyperboloid.
  • these webs or circular webs form so-called partial or radial inlet nozzles for the intake air, the circular webs ensure a constant flow over its entire circumference.
  • the fan wheel is surrounded by an air guide on which the carrier part is mounted in the installed position.
  • the air guide body is provided in a discharge area of the fan wheel with a separate outflow opening depending on the flow direction inflow, via which the air of the fan wheel can be guided.
  • FIG. 1 shows a preferred fan device 1 which can be used in a non-illustrated extractor hood, in a schematic longitudinal section, which has a motor 3 fastened to a carrier part 2, preferably an electric motor for driving a fan wheel 4.
  • the support part 2 has in a Anström Lake of the fan 4, a grid 5, which is formed by a plurality of webs 6.
  • a plurality of openings 17 are defined having walls 18 for conducting the air.
  • the walls 18 and the webs 6 are curved in the cross-sectional direction in such a way that air flowing in via the openings 17 of the grille 5 is supplied to the fan wheel 4 in a three-dimensionally and bum-free manner.
  • the motor 3 is provided with a housing 7, which is fastened to the support part 2 via a fastening device 8, which in the present case are designed as two screwed connections. In the region of the fastening device 8, two electrical contact modules 14 are provided for connecting the motor 3 to a power source.
  • a drive shaft 9 which is fixedly connected to the fan 4 and via which the rotary drive of the fan 4 by the motor 3 takes place.
  • fan 4 is a radial fan, in which a plurality of parallel to the drive shaft 9 extending blades 12 are arranged on a circle.
  • the carrier part 2 has, in the region of the grid 5, a flat central part 10 and an at least approximately frusto-conical outer region 11, which adjoins the middle part 10. Through the truncated-cone-shaped outer region 11 In addition, the flow resistance or a pressure drop during the suction of air through the fan 4 in the outer region 11 of the support member 2 is minimized because the sucked in the outer region 11 of the support member 2 air flows directly in the direction of the fan 4 and the curved Webs 6 in the radial direction on the fan 4 and the blades 12 is supplied.
  • the webs 6 of the grating 5 are convex or concave in the cross-sectional direction, so that sucked air at the webs 6 from a substantially vertical in the central part 10 and 11 in the outer region 11 primarily radial flow to the grid 5 in a radial flow direction the fan 4 is deflected (see arrows 19). Dipped by the attachment or arrangement of the motor 3 in the inflow of the fan 4 and in the fan 4, the space required for the deflection of the sucked air axial space is optimally used, so that the fan device 1 is compact in the axial direction. Another advantage of this arrangement is the integration of Lucasleitmaschineen in the support part. 2
  • FIG. 2 shows a plan view of the carrier part 2 of the fan device 1.
  • the grid 5 is in addition to the webs formed as a circle webs 6 designed by so-called radial webs 13 like a net.
  • the central portion 10 of the support member, to which the motor is attached, has ventilation slots 16 for cooling the engine.
  • the outermost region 15 of the grid 5 is funnel-shaped, so that in cooperation with the circular webs 6 and the radial webs 13, the air is aerodynamically guided to the fan, as shown by the arrows 19 in FIGS. 1 and 2.
