Definitions

  • This invention relates to improvements in air impeller units and deals more particularly with improvements in air impeller units of the type having a housing including an integrally formed motor supporting structure.
  • Molding processes are frequently employed in producing components for such air impeller units.
  • a molding machine having suflicient capacity to produce the impeller component for a given unit may lack the capacity to produce a one-piece housing component to contain it. Consequently, the capital investment for the molding equipment required to produce a given air impeller unit may be determined by the size of the largest component in the unit--namely the housing.
  • the general object of the invention is to provide an air impeller and a housing of improved halfsection construction to facilitate rapid assembly and reduce the alignment operations normally associated with assembly.
  • Another object of this invention is to provide an air impeller construction which in comparison to present units of the same general type omits parts and is of lower manufacturing cost, while nevertheless exhibiting characteristics the same or better than such present air impeller units.
  • a further object of the invention is to provide an improved air impeller unit wherein the size differential between the housing and other molded parts in the unit is substantially reduced, thereby facilitating a reduction in production equipment capacity requirements for producing the unit.
  • FIG. 1 is a side view partially in elevation and partially in section showing an air impeller unit of the axial flow fan type embodying the present invention.
  • FIG. 2 is an end view of the housing of the fan unit of FIG. 1, with a portion of an inlet screen broken away to reveal the motor cradle construction.
  • FIG. 3 is a perspective view of a half section of a housing of the fan unit of FIG. 1.
  • FIG. 4 is an enlarged fragmentary sectional view of an end portion of a motor cradle with the motor in place therein.
  • FIG. 5 is a fragmentary sectional view taken along the line 5--5 of FIG. 2.
  • FIG. 6 is a side elevational view showing the invention embodied in a blower of the transverse flow type.
  • FIG. 7 is an end view of the blower of FIG. 6 showing the motor retaining flange in assembly with the housing, a portion of the housing being broken away to reveal the interior thereof.
  • FIG. 8 is a sectional view through the housing and the motor retaining flange and taken along the line 8-8 of FIG. 7.
  • an axial flow fan embodying the present invention and indicated generally by the numeral 10 comprises a motor 12, at least one air impeller or fan 14, an inlet screen 16, and a housing 18 formed by a pair of substantially identical housing half sections 20, 20.
  • the half sections are adapted to be joined together to secure all of the other components in assembly and in relative alignment.
  • the motor 10 which is preferably electrically powered has a generally cylindrical casing 22 and radially disposed end portions 24, 24 and includes a shaft 26 which coaxially extends from at least one of the end portions.
  • An insulated power cord 28 is provided for connecting the motor with a source of electrical power.
  • the fan unit of the present invention may include fans mounted at opposite ends of the motor, but preferably the device includes a single fan 14 driven by the rotatably motor shaft 26.
  • the fan 14 is molded from plastic material and includes a plurality of radially extending blades 30, 30 each of which is set at a pitch angle to the shaft axis. This pitch angle may vary with performance requirements. It should be noted that when the fan is mounted upon the shaft the blades 30, 30 extend radially beyond the motor casing 22.
  • the fan housing 18 is preferably formed by a pair of substantially identical generally semicylindrical half sections 20, 20 molded from plastic.
  • Each of the housing half sections defines a generally semicylindrical inner Wall surface 32, 32 which wall surfaces together detfine a generally cylindrical fan chamber 34 when the half sections are joined together in assembly.
  • the term generally semicylindrical, as it is used here is intended to include modified cylindrical forms, such as bell shapes.
  • the half sections 20, 20 may be formed with the fan chamber 34 in cluding at least one coaxially extending bell-mouth portion diverging to a chamber end opening to receive the incoming air.
  • a semiannular flanged surface 36 is formed at one end of the half section 20, 20 to provide mounting means for securing the unit to a flange on a supply duct or the like.
  • a means for mounting the unit axially parallel to a mounting surface is provided by a pair of bosses 38, 38 also integrally formed on the outer surfaces of the half sections.
  • the two half sections abut along parallel axially extending edge surfaces 39 and 40 when joined together in assembly. Accurate and rapid alignment of the half sections during assembly is facilitated by a pair of pins 41, 41 extending normal to the edge surface 39, and preferably.
  • the pins 41, 41 cooperate with alignment holes 42, 42 in theedge surface 40 of the mating half section to provide orientation means for properly locating each half section relative to the other when the sections are brought together in assembly.

  • the recesses 43, 43 are preferably formed when the housing half sections are formed in the same mold. Thus, two diametrically opposed apertures in the housing wall are defined when the housing half sections 20, 20 are assembled. Only one of the apertures so formed is required to secure the service cord 28, however, it has been found that the extra or unused aperture does not adversely affect the efficiency of a small fan unit. If desired, this extra aperture may be eliminated by molding the half sections without the clamping surfaces 43, 43 and thereafter forming a single recess in each mating half section 20, 20 by a secondary machining operation.
  • Each of the housing half sections 20, 20 further includes a motor supporting cradle half section 46, 46 maintained in radially spaced relation with the inner wall surface 32, 32 to provide an air passageway 47 therebetween.
  • Support means for maintaining the cradle half section in position is provided by at least one generally radially extending vane integral with both the housing half section and the cradle half section and providing connection therebetween.
  • two vanes 48, 48 are employed.
  • the vanes 48, 48 may be mere supporting elements or they may be formed with a generally airfoil-shaped crosssectional contour to aid the efficient flow of air and minimize turbulence, as shown in FIG. 5.
  • the vanes 48, 48 may also take the form of twisted airfoils comprising substantially complementary extensions of the fan blades 30, 30 thereby further serving a dual function in supporting the motor cradle and aiding in the efficient flow of air through the fan chamber 34.

  • Each cradle half section 46 has a clamping means including a clamping surface 52, complementing the contour of the associated motor casing 22.

  • the abutment surfaces 60 and 62 are adapted to engage the end portions 24, 24 of the casing 22, as best seen in FIG. 1.
  • Each of the housing half sections 20, 20 preferably also includes a recess 68 defined within the wall 32 proximate the inlet end of the fan chamber 34 and adapted to receive and engage an associated edge portion of the inlet screen 16.
  • each recess cooperates with the other to secure the screen against axial and radial movement relative to the chamber 34, thereby maintaining the screen 16 in axial spaced relation with respect to the fan 14.
