Abstract
A ceiling fan that incorporates into its blades both a system for air purification by removing dust and other particulate pollutants from the air in a room through ionization of the air stream passing over an ionizer grid and also a system for heating and cooling the air stream passing over the blades. The device provides a room conditioner for efficiently heating or cooling and maintaining a room at a temperature comfortable to the user. The device also provides negative ion generation through the use of the ionizer.
Claims8
A thermoelectric air-purifying ceiling fan comprising:
- a) a main body
- b) a plurality of fan blades emanating from said main body;
- c) ionization means integral with said fan blades to remove particulate matter from passing air;
- a thermoelectric means integral with said fan blades for transferring heat to or from said passing air as needed to achieve a selected temperature, wherein said fan blade comprises an upper half, a lower half and a leading edge and said thermoelectric means comprises a thermoelectric plate having a positive side and a negative side disposed on said upper half of said fan blade with a plurality of spaced apart radiative fins extending from the top portion thereof and a thermoelectric plate having a positive side facing the positive side of said upper thermoelectric plate and a negative side disposed on said lower half of said fan blade with a plurality of spaced apart radiative fins extending from the top portion thereof.
