Definitions

  • the present invention pertains to a blower assembly for an air handler in which an electric motor is integrated into the constructions of the impeller fan and the blower housing of the blower assembly. More specifically, the present invention pertains to a blower assembly in which an axial flux motor has its stator integrated into the construction of the blower housing of the assembly and has its rotor integrated into the construction of the impeller fan of the assembly.
  • the typical construction of a blower assembly for an air handler for example as a furnace, includes a fan that is rotated by an electric motor and a blower housing that contains the fan.
  • the typical blower housing is comprised of a scroll-shaped outer wall and a pair of side walls that are connected to opposite sides of the scroll-shaped outer wall.
  • the outer wall has opposite ends that are positioned on opposite sides of an outlet opening of the blower housing.
  • the side walls are also positioned on opposite sides of the outlet opening.
  • the side walls have circular, coaxial holes through the side walls that function as air inlet openings of the blower housing.
  • the motor is typically mounted to one of the blower housing side walls.
  • the shaft of the motor is coaxial with the center axes of the blower housing inlet openings. This positions the motor either directly adjacent one of the side wall inlet openings, or in some constructions, the motor extends through the side wall inlet opening into a portion of the motor housing interior.
  • the impeller fan is mounted to the motor shaft in the blower housing interior.
  • the typical impeller fan has a circular plate at one axial end of the fan or at an intermediate portion of the fan that is connected to the motor shaft.
  • the common blower assembly construction described above includes features that detract from the efficiency of the blower assembly. Positioning the motor adjacent or partially extending into one of the air inlet openings of the blower housing restricts the air flow through that inlet opening and thereby contributes to the inefficiency of the blower assembly. Additionally, the circular plate of the impeller fan that connects the fan to the motor shaft restricts the free flow of air through the interior of the impeller fan and thereby also contributes to the inefficiency of the blower assembly.
  • the blower assembly of the present invention overcomes disadvantages associated with the constructions of conventional blower assemblies by having the construction of the motor integrated into the constructions of intermediate portions of the impeller fan and the blower housing. This eliminates the prior art positioning of the motor adjacent one of the blower housing inlet openings or extending through one of the blower housing inlet openings and thereby eliminates the inefficiencies associated with this prior art positioning of the motor.
  • the portion of the motor integrated into the fan construction includes a cylindrical hub with a center bore through the hub that balances pressure and the free flow of air through the interior of the fan.
  • the blower housing of the invention comprises a scroll-shaped outer wall having a length with opposite first and second ends that are positioned at opposite sides of the outlet opening of the housing.
  • the housing also comprises a pair of side walls that are secured to the opposite sides of the scroll-shaped outer wall.
  • the side walls have circular holes that are coaxially aligned and function as the air inlet openings of the blower housing.
  • the novel construction of the blower housing of the invention includes an interior wall.
  • the interior wall is parallel to the side walls and is secured stationary to the interior surface of the housing outer wall at a centered position between the two side walls.
  • the interior wall has a circular hole through the wall that is coaxial with the air inlet openings of the two side walls.
  • the motor of the blower assembly is mounted to the interior wall of the blower housing. This eliminates the inefficiencies associated with the prior art positioning of the motor adjacent an air inlet opening of the prior art blower housing or extending into the air inlet opening of the prior art blower housing.
  • the preferred motor is an axial flux motor having a circular stator construction integrated into the construction of the interior wall at the hole through the wall.
  • the wiring associated with the stator and the control systems of the motor are run through or along the interior wall to the exterior of the blower housing.
  • the rotor of the motor includes a hollow cylindrical hub that is mounted for rotation by one or more bearings inside the stator.
  • the hub has a pair of annular plates connected to the axially opposite ends of the hub. The plates extend radially outwardly from the center hub over opposite sides of the interior wall.
  • the magnets of the motor are secured to at least one of the plates.
  • the impeller fan of the blower assembly is comprised of a pair of centrifugal or squirrel-cage fans. These fans may have different width dimensions for air flow purposes.
  • the fans are positioned on the opposite sides of the interior wall and are connected to the pair of plates that extend radially from the cylindrical hub of the rotor.
  • the blower assembly of the invention described above has no obstructions to the free flow of air through the inlet openings of the blower housing side walls into the interior of the fan contained in the blower housing.
  • the blower assembly also has a smaller size than comparable prior art blower assemblies that have motors that project out from one side of their blower housings. This enables the blower assembly of the invention to be used in a narrower air handler enclosure. This is accomplished by the positioning of the motor in the interior of the housing on the interior wall of the housing.
  • Employing the axial flux motor construction allows for the free flow of air through the interior of the blower housing between the two centrifugal fans. This eliminates the inefficiencies associated with prior art centrifugal fans due to the center plates of the fans restricting air flow through the fans.

Additionally, the first 22 and second 24 end edges of the outer wall 18 define opposite sides of a rectangular outlet opening 26 of the blower housing.
  • the blower housing also includes first 28 and second 32 side walls. As seen in the drawing figures, portions of the peripheries of the two side walls 28 , 32 are connected to the opposite sides of the outer wall 18 .
  • the first 28 and second 32 side walls also have respective straight edge portions 34 , 36 .
  • the straight edge portions 34 , 36 of the two side walls are also positioned at opposite sides of the blower housing outlet opening 26 and with the outer wall first end edge 22 and second end edge 24 define the rectangular configuration of the outlet opening.
  • Each of the side walls 28 , 32 is also provided with a circular hole 38 , 42 through the side wall.
  • the circular holes 38 , 42 are coaxially aligned and function as the air inlet openings of the blower housing 12 .
  • FIGS. 5-11 An interior wall 44 of the blower housing 12 is shown in FIGS. 5-11 .
  • the interior wall 44 is a flat, planar wall having a circular center hole 46 through the wall.
  • the interior wall 44 is secured to the interior surface of the blower housing outer wall 18 and is positioned in the interior of the blower housing 12 parallel to the side walls 28 , 32 .
  • the interior wall center hole 46 is coaxial with the inlet openings 38 , 42 in the respective side walls 28 , 32 .
  • the hole 46 through the wall 44 allows a balance of air pressure and air flow on opposite sides of the blower housing interior.
  • the wall 44 could be replaced by a ring having the center hole 46 with the ring connected to the housing interior by three or more circumferentially spaced spokes or webs.
  • the interior wall 44 is shown in the drawing figures centered in the blower housing 12 relative to the side walls 28 , 32 . In alternate embodiments of the invention, the interior wall 44 could be positioned off center in the blower housing 12 and more toward one or the other of the side walls 28 , 32 . Optimum efficiency is achieved when the interior wall concept is employed in a high efficiency blower housing such as those described in pending patent application Ser. Nos. 11/935,726; 12/178,161 and 12/631,415; all of which are incorporated herein by reference.
  • the motor 16 of the blower assembly is an axial flux motor.
  • the stator 52 of the motor is integrated into the construction of the housing interior wall 44 at the center hole 46 through the wall.
