Abstract

A hair dryer has a primary air flow path and a secondary air flow path. The primary air flow path is operable to dry hair using suction in a first mode of operation. The secondary air flow path is operable to blow dry hair in a second mode of operation. In the primary mode of operation, the motor and fan assembly of the secondary air flow path is operated in reverse to direct air towards hair that is being dried by suction.

Claims (27)

1. A hair dryer having a front air inlet end and a rearwardly positioned opposed second end, the hair dryer comprising:

(a) an air flow path extending through the hair dryer;

(b) a fan and motor assembly provided in the air flow path; and,

(c) a water separator provided in the air flow path upstream of the fan and motor assembly, the water separator comprising a water separator volume positioned between a water separator air inlet end and a water separator air outlet end that is positioned rearwardly from the water separator air inlet end, a water separator air inlet comprising a water separator inlet port defining an entrance to the water separator volume, an air outlet conduit extending forwardly into the water separator volume from the water separator air outlet end, a screen provided in the water separator volume in a water separator air flow path between the water separator inlet port and an inlet end of the air outlet conduit, wherein the inlet end of the air outlet conduit is located forward of the water separator inlet port.

2. The hair dryer of claim 1 wherein the screen comprises an inlet port screen that is provided on the water separator inlet port.

3. The hair dryer of claim 2 wherein the screen further comprises a first interior screen provided in the water separator air flow path between the water separator inlet port and the inlet end of the air outlet conduit wherein the first interior screen is spaced from the inlet port screen.

4. The hair dryer of claim 3 wherein the first interior screen is provided intermediate the water separator air inlet end and the water separator air outlet end.

5. The hair dryer of claim 4 wherein the screen further comprises a second interior screen provided in the water separator air flow path between the water separator inlet port and the inlet end of the air outlet conduit wherein the second interior screen is spaced from the first interior screen.

6. The hair dryer of claim 5 wherein the second interior screen is provided intermediate the water separator air inlet end and the water separator air outlet end.

7. The hair dryer of claim 3 wherein the air outlet conduit extends through the first interior screen.

8. The hair dryer of claim 1 wherein the screen comprises a first interior screen that is provided intermediate the water separator air inlet end and the water separator air outlet end.

9. The hair dryer of claim 8 further comprising a second interior screen provided in the water separator air flow path between the water separator inlet port and an inlet end of the air outlet conduit wherein the second interior screen is spaced from the first interior screen.

10. The hair dryer of claim 9 wherein the second interior screen is provided intermediate the water separator air inlet end and the water separator air outlet end.

11. The hair dryer of claim 8 wherein the air outlet conduit extends through the first interior screen.

12. The hair dryer of claim 1 further comprising a plurality of water separator inlet ports, wherein the water separator air inlet comprises a plurality of air inlet conduits, each of the air inlet conduits extending from a hair dryer air inlet port to one of the water separator inlet ports, wherein the water separator inlet ports are spaced from each other.

13. The hair dryer of claim 12 wherein the plurality of water separator inlet ports are arranged in an annular pattern.

14. The hair dryer of claim 1 further comprising a foam filter positioned downstream of the inlet end of the air outlet conduit and upstream of the fan and motor assembly.

15. A hair dryer having a front air inlet end and a rearwardly positioned opposed second end, the hair dryer comprising:

(a) an air flow path extending through the hair dryer;

(b) a fan and motor assembly provided in the air flow path; and,

(c) a water separator provided in the air flow path upstream of the fan and motor assembly, the water separator comprising a water separator volume positioned between a water separator air inlet end and a water separator air outlet end that is positioned rearwardly from the water separator air inlet end, a water separator air inlet comprising a water separator inlet port defining an entrance to the water separator volume, an air outlet at least one screen provided in the water separator volume in a water separator air flow path between the water separator inlet port and the air outlet,

wherein as air travels in the air flow path, the air travels in a rearward direction towards the water separator air outlet end and subsequently in a second direction that includes a forward directional component to the air outlet.

16. The hair dryer of claim 15 wherein the second direction is a generally forward direction.

17. The hair dryer of claim 15 wherein the at least one screen comprises at least two spaced apart screens each of which is positioned in the water separator air flow path.

18. The hair dryer of claim 15 wherein the air outlet comprises an outlet conduit and the at least one screen comprises a first interior screen provided in the water separator air flow path between the water separator inlet port and an inlet of the outlet conduit wherein the first interior screen is spaced from the water separator inlet port.

19. The hair dryer of claim 18 wherein the at least one screen further comprises a second interior screen provided in the water separator air flow path between the water separator inlet port and the inlet of the outlet conduit wherein the second interior screen is spaced from the first interior screen.

20. The hair dryer of claim 15 wherein the inlet end of the outlet conduit is located forward of the water separator inlet port.
