Abstract
A turbo fan of a ceiling-embedded cassette type air conditioner. The turbo fan has a shroud for guiding a fluid introduced into the turbo fan, a hub having an outer diameter smaller than an inner diameter of the shroud, so as to facilitate an integral injection molding of the turbo fan, and blades extending between the shroud and the hub and being perpendicular to the shroud and the hub. Each of the blades has an inner diameter decreasingly inclined from the shroud to the hub, so that a quantity of sucked-air and a static pressure can be increased. The turbo fan not only can be integrally formed by injection molding but also can be manufactured at a reduced manufacturing cost.
