Abstract

A portable hand held hair dryer operable in a mode of operation to draw air through hair into the hair dryer. The hair dryer having at least one cyclone operable to separate water from the air flowing therethrough and an exterior separated water storage tank.

First claim

The invention claimed is:

1. A portable handheld hair dryer comprising:
(a) a primary air flow path extending from an inlet port provided on a first side of the hair dryer and extending to an outlet port;
(b) an air moving member provided in the primary air flow path, the air moving member operable in a mode of operation to draw air into the inlet port;
(c) a water separator located in an interior of the primary air flow path inward of the inlet port and upstream of the air moving member; and,
(d) the inlet port comprising a screen, whereby hair is inhibited from entering the water separator.

2. The portable handheld hair dryer of claim 1 wherein the water separator comprises a cyclone having a cyclone air inlet, a cyclone air outlet and a cyclone axis of rotation.

3. The portable handheld hair dryer of claim 2 wherein the cyclone has a plurality of air inlets.

4. The portable handheld hair dryer of claim 2 wherein the hair dryer has a front end and a rear end, a hair dryer axis extends between the front and rear ends and the cyclone axis of rotation extends generally parallel to the hair dryer axis.

5. The portable handheld hair dryer of claim 2 further comprising a water collection tank in fluid flow communication with a separated water outlet of the cyclone.

6. The portable handheld hair dryer of claim 5 wherein the water collection tank is removably mounted in the hair dryer.

7. The portable handheld hair dryer of claim 5 wherein the water collection tank is openable while located in the hair dryer.

8. The portable handheld hair dryer of claim 5 further comprising a reverse flow inhibiting member provided in a flow path from the cyclone to the tank.

9. The portable handheld hair dryer of claim 1 further comprising a heating element upstream of the outlet port and downstream of the air moving member wherein when the heating element is actuated, heated air exits the outlet port whereby in a second mode of operation the hair dryer is also operable to blow dry hair using heated air.

10. A portable handheld hair dryer comprising:
(a) a primary air flow path extending from an inlet port provided on a first side of the hair dryer and extending to an outlet port;
(b) an air moving member provided in the primary air flow path, the air moving member operable in a mode of operation to draw air into the inlet port; and,
(c) a cyclone located downstream of the inlet port in the interior of the hair dryer and upstream of the air moving member.

11. The portable handheld hair dryer of claim 10 wherein the cyclone has a plurality of air inlets.

12. The portable handheld hair dryer of claim 10 wherein the hair dryer has a front end and a rear end, a hair dryer axis extends between the front and rear ends and the cyclone axis of rotation extends generally parallel to the hair dryer axis.

13. The portable handheld hair dryer of claim 10 further comprising a water collection tank in fluid flow communication with a separated water outlet of the cyclone.

14. The portable handheld hair dryer of claim 13 wherein the water collection tank is removably mounted in the hair dryer.

15. The portable handheld hair dryer of claim 13 wherein the water collection tank is openable while located in the hair dryer.

16. The portable handheld hair dryer of claim 13 further comprising a reverse flow inhibiting member provided in a flow path from the cyclone to the tank.

17. A portable handheld hair dryer comprising:
(a) a primary air flow path extending from an inlet port provided on a first side of the hair dryer and extending to an outlet port, wherein air exits the outlet port in a direction of flow;
(b) an air moving member provided in the primary air flow path; and,
(c) a heater provided upstream and adjacent the outlet port, the heater comprising a heating element and a plurality of fins in thermal communication with the heating element wherein the fins extend generally parallel to the direction of flow, and wherein louvres are formed in at least some of the fins.

18. The portable handheld hair dryer of claim 17 wherein the heating element extends generally perpendicular to the direction of flow.

19. The portable handheld hair dryer of claim 18 wherein a plurality of heating elements extend generally perpendicular to the direction of flow.
