Definitions

  • the present invention relates to a fan with a base plate and a plurality of fan blades mounted on the base plate, wherein the fan blades are arranged substantially perpendicular to the base plate and form a substantially radial arrangement, each fan blade one radially outwardly and substantially perpendicular to the base plate arranged front edge, a radially inside and arranged substantially perpendicular to the base plate trailing edge, arranged on the pressure side of the impeller outer surface and arranged on the suction side of the impeller inner surface.
  • Fan wheels are well known in the art and typically serve to circulate air. Fan wheels are known in a variety of forms, for example, fan wheels are known with propeller-like wings or with blade-like wings.
  • One problem with fan wheels known in the art is that particulates and / or liquid particles present in the recirculated air may deposit on the blades of the fan wheel, resulting in fouling of the fan wheel. It can also come through the known fan wheels to an undesirable distribution of the solid and / or liquid particles.
  • the fan wheel is arranged in a cooking appliance mostly in a separate from the cooking chamber via a baffle fan space, sucks air from the cooking chamber and directs them radially to the surrounding walls, so as an air flow within the cooking appliance, from the cooking chamber in the fan room and back to the cooking chamber, to produce.
  • Concentric around the fan around a heater or a heat exchanger is often arranged so that circulating air is also passed to this heater or this heat exchanger to be heated.
  • fat particles present within the circulated air can be conducted to, for example, the heating device, where they can be burned, which can lead to a reduction in the quality of the food and to an odor nuisance.
  • This problem arises in particular when the air within the cooking appliance is permanently circulated through the fan, in which case the solid and / or liquid particles are constantly held in the gas volume by the circulating air flow.
  • DE 42 06 846 C2 discloses a device comprising an impingement surface or a separating ring around the impeller, to which or onto which a gas stream prevailing in the gas volume occurs, with the solid and / or liquid particles at least partially separating off on impact and being able to run to a first discharge region.
  • a fan with a number of radially arranged blades, which project substantially in parallel to the axis of rotation of the fan from a facing on a housing wall of the cooking chamber supporting disk or base plate, in which at least between some of the blades near the support disk, but at a distance from this, baffles are arranged, the radially outer outer edge substantially aligned with the outer periphery of the fan, the radially inner inner edges spaced from the axis of rotation of the fan and with the support disk and the respective adjacent two blades each form a nozzle device for generating a radially outwardly directed gas flow near the support disk.
  • a fan is known in which on the outer surface of at least a portion of the fan blades at least one elevation is arranged, which extends away from the base plate.
  • Object of the present invention is therefore to develop the generic fan to the effect that the disadvantages of the prior art are overcome.
  • it is intended to prevent solids and / or liquid particles present in a circulating air in a cooking appliance from passing directly through the fan wheel onto a heating device or heat exchanger surrounding the fan wheel, without the efficiency of the fan wheel being significantly reduced.
  • the object of the present invention is achieved in that arranged and / or formed on the outer surface of at least a portion of the fan blades at least one elevation which is formed spaced from the base plate and away from the base plate, substantially diagonally from the leading edge to the trailing edge the fan blades extends.
  • the increase in the form of a step is formed on and / or in the outer surface.
  • the fan blades are formed curved so that the outer surface between the leading edge and the trailing edge curves radially outward.
  • At least one increase, at least in some areas, has a height of approximately 1 to 10 mm, preferably 2 to 4 mm.
  • At least one increase at least in regions has a width of 1 to 10 mm, preferably 2 to 4 mm.
  • the fan according to the invention is preferably characterized in that the distance of at least one increase to the base plate at least partially, in particular in the region of the leading edge, at least about 5 to 25 mm, preferably 10 to 20 mm.
  • a support member such as in the form of a bezel, the Lüfterradschaufeln proposed on the opposite side of the base plate of the fan blades.
  • At least one elevation is arc-shaped at least in regions, wherein it preferably bends away from the support member from the respective trailing edge to the respective leading edge.
  • At least one increase at an angle of 45 ° to 90 ° abuts the leading edge, preferably at an angle of 70 ° to 90 °.
  • At least one increase is formed by at least one wire.
  • At least one increase is welded at least partially on the outer surface of the Lüfterradschaufel.
  • each fan blade at least in regions a pronounced edge, such as in the form of a channel, is formed on the side lying in the direction of rotation of the fan wheel in the mounting region between the respective elevation and the outer surface.
  • At least one increase has a profiled cross-section at least in regions, preferably arched, wherein in particular the focal point of the curvature lies on the side of the elevation facing the trailing edge, and / or at least one groove, preferably on the side facing the trailing edge, having.
  • At least one increase on the side facing away from the direction of rotation of the impeller is at least partially sealed with the outer surface, preferably with silicone.
  • An inventive fan may be arranged in a cooking appliance.
  • the present invention is based on the surprising finding that is avoided by elevations on the outer surfaces of fan blades on a base plate on the one hand that contained in circulating air solids and / or liquid particles, in particular in the form of fat particles are deflected directly radially by the fan , Rather, solid and / or liquid particles that hit the outer surfaces of the Lüfterradschaufeln stopped at the increase and derived by the special geometry of the increase in the direction of the base plate. In the region of the base plate, the solid and / or liquid particles can then be released from the fan blades, without hitting devices that are arranged directly radially around the fan, such as a heater within a cooking appliance.
  • the solid and / or liquid particles from the fan blades are not directly on the fan radially surrounding devices, such as a heater dispensed, it prevents in particular fat particles can be burned on the heater, resulting in a reduction in food quality and an odor could lead.
  • the fan according to the invention in a surprising manner that the efficiency of the fan is not significantly affected, since no major obstacles in the radial flow of the circulating air are arranged.
  • the elevations disposed on the outer sides of the fan blades may provide additional stability of the fan blades themselves.
  • FIG. 1 shows a perspective view of a fan according to the invention.
  • the figure shows a perspective view of an inventive fan 1, which is installed in a fan room of a cooking appliance partially shown to rotate in the direction of arrow A rotating air in the cooking chamber, which is partially separated from the fan room by a not shown air deflector.
  • the fan 1 has a base plate 2, on which a plurality of fan blades 3 are arranged, which are turned to the cooking chamber of the cooking appliance.
  • the Lüfterradschaufeln 3 are curved and arranged substantially perpendicular to the base plate 2 to form a substantially radial arrangement on the base plate 2.
  • Each fan blade 3 has a trailing edge 5 contacting the air to be circulated first during operation, and an outer surface 6 arranged on the pressure side of the fan wheel 1 during operation.
  • an elevation 7 is provided, which extends away from the base plate 2, substantially diagonally from a front edge 4 to the trailing edge 5 of the Lüfterradschaufel 3.
  • the elevation 7 is arranged at a distance of 10 to 20 mm from the base plate 2 on the outer surface 6.
  • the elevation 7 may extend completely over the entire width of the Lüfterradschaufel 3, or have a distance from the base plate 2 opposite side of the Lüfterradschaufel 3, wherein this distance is preferably 5 to 15 mm.
  • a cover ring 8 is provided, which provides additional stabilization of the fan blades 3 within the fan 1.
  • the elevation 7 should stand out from the outer surface 6 of the Lüfterradschaufel 3 by 2 to 5 mm and end at the end facing the air flow on the trailing edge 5 of the Lüfterradschaufel 3 with a sharp edge to a gutter for impinging solid and / or liquid particles form, which prevents further flow of the solid and / or liquid particles beyond the elevation 7, but causes a guiding in the direction of the base plate 2.
  • a seal may be provided on the side lying in the flow shadow between the outer surface 6 and elevation 7.
  • This seal may be made, for example, with silicone, but any other seal may be provided which would be obvious to those skilled in the art.
  • the fan 1 is rotated in the fan chamber via an engine, not shown in the figure in the direction of arrow A and thus sucks air from the cooking chamber via a central opening in the air baffle centrally and directs them radially outwards, so that they outside of the fan room passes through the baffle again in the cooking chamber.
  • Solid and / or liquid particles in particular fat particles of different sizes, which reach in the area of the fan wheel 1, impact on the outer surfaces 6 of the fan blades 3, on the pressure side of the fan wheel, and are discharged along the elevation 7 in the direction of the base plate 2 , If the solids and / or liquid particles reach the end region of the elevation 7 at the front edge 4 of the fan blade 3 (and finally the base plate 2), then the solid and / or liquid particles then released can not directly contact a device radially surrounding the fan wheel 1, such as in the form of a heater, not shown, or a heat exchanger, not shown, are discharged.
  • a device radially surrounding the fan wheel 1 such as in the form of a heater, not shown, or a heat exchanger, not shown
