Definitions

  • a singlestage fan system is utilized to provide a cleaner with relatively lower performance and also cost. Discharge of air from this system is downwardly through an orifice in the bottom pan so that a cushion of air is formed beneath the cleaner to give it an air ride" characteristic.
  • a supplemental pan disposed between the bottom pan and intermediate shell permits the entrance of cooling air for cooling cleaner air discharge. This air enters the cleaner radially around an annular periphery between the outer diametric extents of the bottom pan and supplemental pan. This cooling air then passes between these members to enter the fan system, proper, through the diffuser therefor.
  • FIG. 4B is a fragmentary, elevational view of the ring member
  • a resilient annular ring member 62 Disposed in receiving grooved section 54 of bottom pan 18 is a resilient annular ring member 62 that forms the first, lower resilient support means for the motor 22 and fan system 24 of the canister cleaner 10.
  • This resilient annular ring member takes its shape (FIGS. 4-4D) from a series of spaced, solid, resilient material spheres 64 that are arranged in a circle and integrally joined by a horizontally extending thin, flat, annular ring 66 of the same material, disposed centrally relative to the height of spheres 64 so as to, in effect, cut the spheres into vertically attached hemispheres.
  • the inner and outer peripheries of the annular ring form a circumference equal to the general circumference of the spaced spheres 64.
  • the larger one essentially below and radially inward of the periphery of diffuser 70, and the other, smaller one, further inward from the periphery of diffuser 70 and mounted in a grooved portion 108 of intermediate shell 14, resting on a curved surface 91 formed in motor mounting plate 90, permits the use, overall, of a relatively small diameter assemblage for the resilient mounting means, fans, diffusers and motor.
  • This last-named pan is vertically spaced from, but conforms generally in configuration to bottom pan 18 at its outer, radial portions and maintains this vertical spacing, except for a series of three bolt-receiving indents 41, 41, 41 (only one shown), and except at an inner terminating, receiving grooved portion 43 extending annularly around intermediate pan 19 and abuttingly and matingly engaging within grooved portion 54' of bottom pan 18.
  • Suction cleaner air within canister cleaner l flows from the dirt-collecting bag into a motor housing 38' of motor 22' through a series of elongated apertures, e.g., 114. 116' and 118 in motor housing 38 and then passes through the motor 22 in the manner described relative to the first embodiment and enters the eye of the fan 26 to be discharged therefrom.
  • a flow of induced, cooling ambient air is provided to cool the discharge of the hot suction cleaner air by gaining entrance to the cleaner through a peripheral opening afforded by the space between bottom pan l8 and intermediate pan 19.
  • This cooling air passes between these two elements as they extend beneath the first resilient ring member 62 and then is discharged into a space 85, between the bottom face of diffuser 70' and the top surface of bottom 18.
  • the cooling air is then induced to flow through a series of apertures 124 in diffuser 70 where it mixes with the discharge air from fan 26 and the mixed air then flows through diffuser 70 to be discharged between the bottom face of intermediate shell 14 and the top face of intermediate pan 19; Air is eventually discharged to atmosphere through the blower opening 35, as set out previously.
  • said first resilient means directly and abuttingly engages said bottom pan.
  • said one and said second annularly extending connecting means are disposed at right angles to each other so that said spheres are, in effect, divided into quadrants, whereby said annular means, while made of a relatively high durometer material of high durability, exhibits a softened resiliency characteristic.
