Patent ID: 8167590

Claim:
A pedestal fan device comprising: (a) a pedestal base having an inner cavity; (b) a support component having an inner cavity, the support component extending upwardly from the pedestal base; (c) a fan housing mounted to a first end of the support component, the fan housing having an inner cavity, a front surface, and a back surface, wherein an open hole is disposed in the front surface and a plurality of fan blades are rotatably disposed in the inner cavity of the fan housing, wherein the plurality of fan blades are operatively connected to a motor that drives the rotation of the fan blades; (d) a first door component disposed in the back surface of the fan housing, the first door component can move between an open position and a closed position respectively allowing and preventing air access to the inner cavity of the fan housing; (e) a second door component disposed in a side portion of the pedestal base, the second door component can move between an open position and a closed position respectively allowing and preventing air access to the inner cavity of the pedestal base; and (f) a third door component disposed in a bottom surface of the pedestal base, the third door component can move between an open position and a closed position respectively allowing and preventing air access to the inner cavity of the pedestal base; (g) wherein the inner cavity of the pedestal base is fluidly connected to the inner cavity of the support component and the inner cavity of the support component is fluidly connected to the inner cavity of the fan housing, such that when the second door component is in the open position, the fan blades induce a flow of air from an air source through the opened second door component into the inner cavity of the pedestal base, then into the inner cavity of the support component, then into the inner cavity of the fan housing, then out the open hole in the front surface of the fan housing, and, such that when the third door component is in the open position, the fan blades induce a flow of air from the air source through the opened third door component into the inner cavity of the pedestal base, then into the inner cavity of the support component, then into the inner cavity of the fan housing, then out the open hole in the front surface of the fan housing.
