Abstract

An all season fan with heated circulating blades which includes a heating elements mounted in slots defined in the rear surface of the fan blades for heating of air blown outwardly therefrom. Resilient biasing devices such as a bow springs are mounted in the fan blades extending over the slots to retain the heating elements in the slots. Electrically conductive ball bearings are included to facilitate rotation of the fan blade and hub while simultaneously providing electrical power to the heating elements during fan rotation. At least two bearings each individually maintain separate electrically conductive abutment respect to two separate conductive rings mounted in an insulating insert within the fan hub. Each ring is electrically conductive with respect to one end of each heating element for heating thereof during fan rotation.

2. An all season heat fan apparatus as defined in claim 1 further comprising:

A. a fan means fixedly secured with respect to said fan hub and including a plurality of individual fan blades extending outwardly from said fan hub, each fan blade defining a slot means therewithin; and

B. a heating means positioned at least partly within said slot means defined in said fan blades to facilitate heating of air being blown therefrom.

3. An all season heat fan apparatus as defined in claim 1 wherein said electrical conductor means includes:

A. a first electrical conductor fixedly mounted with respect to said housing and extending outwardly therefrom; and

B. a second electrical conductor fixedly mounted with respect to said housing and extending outwardly therefrom.

4. An all season heat fan apparatus as defined in claim 3 wherein said ball bearing means includes:

A. a first ball bearing means rotatably mounted on said first electrical conductor and in electrical conductance therewith; and

B. a second ball bearing means rotatably mounted on said second electrical conductor and in electrical conductance therewith, said second ball bearing means being electrically insulated from said first ball bearing means.

5. An all season heat fan apparatus as defined in claim 4 wherein said ring means includes:

A. a first ring member fixedly mounted within said fan hub in position maintaining electrically conductive contact with said first ball bearing means during rotational driving of said fan means; and

B. a second ring member fixedly mounted within said fan hub in position maintaining electrically conductive contact with said second ball bearing means during rotational driving of said fan, said second ring member being electrically insulated from said first ring member.

6. An all season heat fan apparatus as defined in claim 5 wherein each of said heating means located on each of said fan blades includes a first heating end and a second heating end and wherein all of said first heating ends are maintained in electrically conducting contact with respect to said first ring member during rotational movement of said fan and wherein all of said second heating ends are maintained in electrically conducting contact with respect to said second ring member during rotational movement of said fan.

7. An all season heat fan apparatus as defined in claim 2 further comprising a plurality of holding members mounted to said fan blades adjacent said slots means defined therein for extending thereover to facilitate retaining of said heating means in position thereadjacent extending at least partially within said slot means.

8. An all season heat fan apparatus as defined in claim 7 wherein each of said holding members includes a bow spring member extending over said heating means for biasing thereof into said slot means.

9. An all season heat fan apparatus as defined in claim 5 further comprising a hub insert member positioned within said fan hub with said first ring member and said second ring member mounted therewithin spatially disposed from one another, said hub insert member being made of an electrically insulating material to facilitate electrical insulation of said first ring member and said second ring member.

10. An all season heat fan apparatus as defined in claim 9 wherein said hub insert member is made of a silicone based material to facilitate electrical insulation thereof.

11. An all season heat fan apparatus as defined in claim 3 further comprising a first collet assembly and a second collet assembly mounted with respect to said housing, said first collet assembly and said second collet assembly being made of electrically insulative material, said first electrical conductor means being mounted within said first collet assembly and said second electrical conductor means being mounted within said second collet assembly to facilitating electrical insulation therebetween and also for electrical insulation from said housing.

12. An all season heat fan apparatus as defined in claim 11 wherein said housing includes a front cover member with said first collet assembly and said second collet assembly mounted therein spatially disposed from one another.

13.
