Bladeless ceiling fan
A ceiling fan comprising a stationary inner housing defining a first interior, a stationary outer housing that circumscribes at least a portion of the stationary inner housing and defines a second interior, a motor assembly located within the first interior and having a rotor, and a plurality of blades extending between corresponding roots and tips, with the roots coupled to the rotor and the tips extending toward to the outer housing. The tips are coupled to a tip housing that can at least partially be received within a portion of the outer housing. A flow channel is formed between the stationary inner housing and the stationary outer housing.
1. A ceiling fan comprising:
a stationary inner housing defining a first interior and having a circumferential rotor channel;
a stationary outer housing, circumscribing at least a portion of the stationary inner housing to define a flow channel therebetween, and defining a second interior having a circumferential tip channel;
a motor assembly located within the first interior and having a rotor aligned with the rotor channel;
a plurality of blades extending between corresponding roots and tips, with the roots coupled to the rotor; and
a tip housing coupled to the tips of the blades and at least partially received within the tip channel.
2. The ceiling fan of claim 1 , wherein the tip housing extends fully along the tips.
3. The ceiling fan of claim 2 , wherein the blades have corresponding leading edges and trailing edges extending from the roots to the tips, and the tip housing extends along at least a portion of the leading edges or the trailing edges.
4. The ceiling fan of claim 3 , wherein the tip housing extends along at least a portion of both the leading edges and trailing edges.
5. The ceiling fan of claim 1 , wherein at least a portion of the tip housing is received in the second interior.
6. The ceiling fan of claim 1 , wherein the stationary outer housing is radially spaced from the stationary inner housing to form a radial gap that defines the flow channel.
7. The ceiling fan of claim 6 , wherein the rotor channel and tip channel at least partially overlap axially.
8. The ceiling fan of claim 7 , further comprising struts coupling the stationary outer housing to the stationary inner housing.
9. The ceiling fan of claim 8 , wherein the struts are vanes.
10. The ceiling fan of claim 1 , wherein the stationary inner housing has a contoured first surface forming at least a portion of the flow channel.
11. The ceiling fan of claim 10 , wherein the stationary outer housing has a contoured second surface forming at least a portion of the flow channel.
12. The ceiling fan of claim 11 , wherein the tip channel is located within the contoured second surface.
13. The ceiling fan of claim 12 , wherein the tip housing closes the tip channel.
14. The ceiling fan of claim 13 , wherein the tip housing comprises an outer surface following a contour of the contoured second surface.
15. The ceiling fan of claim 1 , wherein the tip housing closes the tip channel.
16. The ceiling fan of claim 1 , further comprising an air splitter fluidly coupled to the flow channel.
17. The ceiling fan of claim 16 , wherein the air splitter is located at an inlet to the flow channel.
18. The ceiling fan of claim 1 , further comprises a light carried by at least one of the stationary outer housing or the stationary inner housing.
19. The ceiling fan of claim 18 , wherein the light is a plurality of light emitting diodes.
