  • Motor-fan assembly for a floor cleaning machine
    Patent number: 6666660
    Abstract: A motor-fan assembly for a floor care appliance having an improved working air fan for increased performance and noise reduction, a working air fan housing cover having a plurality of spiral shaped grooves, and a motor cooling air fan housing cover with slot shaped vent openings for increased cooling performance. The working air fan has a larger number of blades as compared to conventional fans wherein the blades are of two different lengths arranged in an alternating pattern circumferentially on an annular shaped disc. The blades are spaced closer together to prevent the passage of debris between adjacent blades and also to reduce flow noise. The passage between the edges of the fan blades and the working air fan cover has been widened and made uniform to aid in the passage of debris over the top of the working air fan.
