Definitions

  • the present invention relates to a fan particularly adapted to be used in ventilation assemblies of kitchen ovens.
  • fans used in kitchen ovens are constituted by so-called cross-flow drum fans.
  • such fans are constituted by a substantially cylindrical drum made of sheet metal (or plastic material), which accommodates internally an impeller whose vanes are arranged parallel to the internal surface of the drum.
  • An intake port and a delivery port are provided in the drum; the intake port is generally provided by a rectangular window which lies longitudinally with respect to the drum, while the delivery port is arranged substantially parallel to the intake port but on the opposite side of the drum with respect to the rotation axis of the impeller.
  • the air drawn by the fan through the intake port is propelled, through the delivery port, into a duct (or conveyance element), which guides it toward a front opening which is arranged between the control panel and the front door of the oven.
  • the aim of the present invention is to eliminate or at least reduce drastically the drawback noted above in known types of fans particularly for kitchen ovens.
  • an object of the present invention is to provide a fan which has a competitive production cost, so that its use is advantageous also from an economical standpoint.
  • Another object of the invention is to provide a fan which can offer high reliability in operation.
  • Still another object of the present invention is to provide a fan which has a very simple structure which is highly durable and easy to assemble.
  • a fan according to the invention particularly for the ventilation of kitchen ovens, characterized in that it comprises a supporting structure associated with at least one impeller which can be actuated by motor means and is adapted to draw an air stream which is oriented in a direction which is substantially parallel to the axis of said impeller, and conveyance means which are adapted to redirect the air stream in a direction which is substantially perpendicular to the axis of said impeller.
  • the present invention relates to a fan, particularly for the ventilation of kitchen ovens, which comprises a supporting structure associated with an impeller and means for conveying the air stream generated by said impeller to a delivery port which is connected to a conveyance duct which leads into the region of the oven closure door, characterized in that said conveyance means and said conveyance duct are formed monolithically.
  • a fan particularly for the ventilation of kitchen ovens is generally designated by the reference numeral 1 and comprises a supporting structure 2 which is associated with at least one impeller 3.
  • the impeller 3 has an axis 3a with respect to which a plurality of mutually angularly spaced vanes 3b protrude radially.
  • the impeller 3 can be actuated by motor means 4 and is adapted to draw an air stream which is oriented along a direction which is substantially parallel to its axis 3a.
  • the fan 1 is further provided with conveyance means 5, which are adapted to redirect the aspirated air stream generated (at the intake) by the impeller 3 along a direction which is substantially perpendicular to the axis of said impeller 3.
  • the conveyance means 5 comprise a lateral containment body 6 and at least one closure wall 7, which faces the impeller 3.
  • the closure wall is designed to be arranged, in the particular application of kitchen ovens, below the impeller 3.
  • the closure wall 7 is at least partially formed by an upper closure housing 7a of the oven with which the fan 1 is associated.
  • closure wall 7 in a different manner, for example by providing monolithically (and in a single die) both the lateral containment body 6 and the closure wall 7.
  • the lateral containment body 6 defines an intake port 8, which is arranged axially with respect to the axis 3a of the impeller 3, and a delivery port 9, which is arranged laterally with respect to the axis 3a of the impeller 3.
  • the delivery port 9 can be connected to a duct 10 for conveying the air stream: said conveyance duct 10 leads into the region of the oven closure door and typically substantially at a front opening arranged between the control panel and the front door of the oven.
  • the conveyance duct 10 also, as shown, can be formed in a downward region by a portion of the upper closure housing 7a.
  • the conveyance duct 10 is formed monolithically with the lateral containment body 6.
  • the motor means 4 can be constituted by an electric motor 4a, which can be supported by the upper closure housing 7a of the oven (or by the supporting structure 2) and is connected axially, with its output shaft, to the impeller.
  • the lateral containment body 6 has, on its outer side, elements 6a (such as openings which can be engaged by screws or similar elements) for fixing it to the upper closure housing 7a.
  • the lateral containment body 6 may support a supporting collar 11 for the impeller 3 and for the motor means 4.
  • the present invention relates to a fan 1 particularly for the ventilation of kitchen ovens which comprises a supporting structure 2 which can be associated with an impeller 3 and means 5 for conveying the air stream generated by the impeller 3 to a delivery port 9, which is connected to a conveyance duct 10 which leads to the region of the oven closure door.
  • the conveyance means 5 and the conveyance duct 10 are provided monolithically.
  • said monolithic body can be provided by using a single die.
  • the conveyance means from comprising a lateral containment body which defines an intake port which is arranged laterally with respect to the axis of said impeller: in this case, the delivery port is arranged on the opposite side of the intake port with respect to the axis of the impeller so as to form in practice a cross-flow fan.
  • the impeller 3 is turned and draws the air through the intake port 8 (therefore axially) and directs it toward the delivery port 9 and from there through the conveyance duct 10.
  • the production cost has been further reduced and the die has been simplified so as to allow optionally to provide monolithically the conveyance means and the conveyance duct.
  • the materials used, as well as the contingent shapes and dimensions may be any according to requirements.
