Definitions

  • the fan and motor assembly may further comprise a vortex finder.
  • the vortex finder may have an outlet that communicates with an inlet of the first rotating fan blade subassembly.
  • the position of the vortex finder to the inlet may be adjustable between a first position in which the fan and motor assembly is in the first configuration and a second position in which the fan and motor assembly is in the second configuration.
  • the position of the first set of vanes with respect to the second set of vanes may be adjustable between a first position and a second position.
  • the first position the first set of vanes may be adjacent the second set of vanes and a first number of stationary vane air channels is provided.
  • the second position the first set of vanes may be spaced from the second set of vanes and a second number of stationary vane air channels is provided and the second number of stationary vane air channels is greater than the first number of stationary vane air channels.
  • the first rotating fan blade subassembly may have a first plurality of rotatable blades
  • the second rotating fan blade subassembly may have a second plurality of rotatable blades and a pitch of at least one of the first and second plurality of rotatable blades may be adjustable.
  • FIG. 1 F is a cross-sectional view of the fan and motor assembly of FIG. 1A and a vortex finder, the vortex finder shown positioned relative to the fan and motor assembly to promote enhanced suction;
  • FIG. 11A is a perspective view of a further alternative embodiment of a rotating fan blade subassembly and a stationary vane subassembly;
  • the second set of vanes may be positioned so that each vane 150b of the second set of vanes is positioned at an equidistance to each adjacent vane 150a of the first set of vanes. It is to be understood that the second set of vanes can be positioned at any distance between adjacent vanes 150a of the first set of vanes. [0161] Alternately, or in addition, the axial position of the rotating fan blade assembly to the stationary vane assembly may also be adjustable.
  • the vanes 150 of the first stationary vane subassembly 108 and the vanes 150 of the second stationary vane subassembly 108b may together define a set of combined vanes.
  • a combined vane of the set of combined vanes may positively overlap with an adjacent combined vane.
  • a combined vane of the set of combined vanes may have no overlap with adjacent combined vanes (see, FIG. 7A). In this position, the first and second stationary vane subassemblies 108, 108b may promote suction.
  • outlets 192 that are closer to the distal end 180 of the inner and outer vortex finders 142a and 142b are aligned such that air exits the vortex finder 142 through outlets 192 that are provided, and enters the flow channels of the first rotating fan blade subassembly 106.
  • the axially inner outlets 192 of the inner and outer vortex finders 142a and 142b are offset such that air is inhibited from exiting through the axially inner outlets 192 into the flow channels of the second rotating fan blade assembly 106b.
  • the first and second vortex finders 142a, 142b cooperate to direct airto the second rotating fan blade subassembly 106b.

Abstract

L'appareil électroménager selon l'invention comporte un trajet d'écoulement d'air s'étendant depuis un orifice d'entrée d'air vers un orifice de sortie d'air, un ensemble ventilateur et moteur se situant dans le trajet d'écoulement d'air. L'ensemble ventilateur et moteur comprend un moteur relié par entraînement à un sous-ensemble pales de ventilateur rotatif. L'ensemble ventilateur et moteur est réglable entre une première configuration, dans laquelle le sous-ensemble pales de ventilateur rotatif fournit un premier niveau d'écoulement d'air et un premier niveau d'aspiration, et une seconde configuration dans laquelle le sous-ensemble pales de ventilateur rotatif fournit un second niveau d'écoulement d'air et un second niveau d'aspiration, le premier niveau d'écoulement d'air étant supérieur au second niveau d'écoulement d'air, et le second niveau d'aspiration étant supérieur au premier niveau d'aspiration.
