Abstract

An electric ceiling fan that is suitable for safe operation in outdoor conditions and is capable of being subjected to high pressure washing without damage.

Claims (4)

1. An electric ceiling fan that is suitable for safe operation in outdoor conditions and is capable of being subjected to high pressure washing without damage in accordance with an IP66 standard rating defined by the International Electrotechnical Commission (IEC); wherein said fan comprises an electrical rotor and stator that are sealed within a two part cover having a rotor cover and a bottom stator cover; and wherein a sealing gasket is located between said rotor cover and said bottom stator cover; and wherein said electrical rotor has an upwardly extending motor shaft; and wherein said rotor and stator are suspended from a downrod via an intermediately disposed down rod jointer that is adapted to receive and make sealing engagement, at its upper end with the downrod, and to receive and engage, at its lower end, said motor shaft; and wherein said downrod jointer has a groove running around the outside of said upper end that is adapted to receive an O-ring or similar sealing part, which is adapted to make a sealing engagement with the inside of a jointer cover or canopy, and wherein there is located, between said down rod jointer and said down rod, a gasket seal; and wherein said fan further comprises upper and bottom covers located respectively above and below said rotor cover and said bottom stator cover of said two part cover.

2. The ceiling fan of claim 1 , incorporating a bearing located around said motor shaft and above said stator; further incorporating a dust cover above said bearing and rotor cover.

3. A method of making an electric ceiling fan, said ceiling fan including an electrical rotor and stator, wherein said electrical rotor has an upwardly extending motor shaft; and wherein said rotor and stator are suspended from a downrod, safe for operation in outdoor conditions and capable of being subjected to high pressure washing without damage in accordance with an IP66 standard rating defined by the International Electrotechnical Commission (IEC), said method including the steps of: sealing said rotor and stator within a two part cover having a rotor cover and a bottom stator cover and placing a sealing gasket between said rotor cover and said bottom stator cover; and the step of intermediately disposing a down rod jointer between said down rod and said motor shaft, wherein said down rod jointer is adapted to receive and engage, at its upper end, the downrod, and to receive and engage, at its lower end, the motor shaft, and wherein said downrod jointer has a groove running around the outside of said upper end that is adapted to receive an O-ring or similar sealing part, which is adapted to make a sealing engagement with the inside of a jointer cover or canopy, and further including the steps of placing a gasket seal between said down rod jointer and said down rod; and placing upper and bottom covers respectively above and below said rotor cover and said bottom stator cover of said two part cover.

4. The method of claim 3 , incorporating a bearing located around said motor shaft and above said stator; further incorporating a dust cover above said bearing and rotor cover.
