Abstract

A hair dryer assembly generally comprises a hair dryer and a discharge housing. The hair dryer includes a body defining a cavity, an inlet for airflow to enter the cavity, and an outlet for airflow to exit the cavity. The discharge housing is configured to receive the airflow from the outlet, and includes an inlet end, a closed end opposite the inlet end, and a channel wall intermediate the inlet end and the closed end. The channel wall defines a hair receiving channel and an outlet for airflow to exit the discharge housing. The channel wall extends continuously around the hair receiving channel such that hair within the channel is surrounded by the channel wall. The outlet is configured to direct airflow out of the discharge housing and towards hair within the hair receiving channel. The discharge housing also includes a sidewall extending at least partly around the channel wall.

Claims (35)

1. A hair dryer assembly comprising:

a hair dryer having a body defining a cavity, an inlet for airflow to enter the cavity, and an outlet for the airflow to exit the cavity; and

a discharge housing configured to receive the airflow from the outlet, wherein the discharge housing comprises:

an inlet end defining an inlet for the airflow to enter the discharge housing;

a closed end opposite the inlet end;

a channel wall intermediate the inlet end and the closed end, the channel wall defining a hair receiving channel and an outlet for airflow to exit the discharge housing, the channel wall extending continuously around the hair receiving channel such that hair within the channel is surrounded by the channel wall, wherein the outlet is configured to direct the airflow out of the discharge housing and towards hair within the hair receiving channel; and

a sidewall extending at least partly around the channel wall, the sidewall and the channel wall defining a space for the airflow to travel through the discharge housing.

2. A hair dryer assembly as set forth in claim 1 , wherein the discharge housing is releasably attached to the body.

3. A hair dryer assembly as set forth in claim 1 , wherein the discharge housing further comprises a top extending between the inlet end and the closed end and a bottom opposite the top, the channel wall extending from the top toward the bottom.

4. A hair dryer assembly as set forth in claim 3 , wherein the channel wall and the sidewall define the outlet.

5. A hair dryer assembly as set forth in claim 4 , wherein the discharge housing further comprises a flow guide extending at least partly through the space and configured to direct the airflow towards the outlet.

6. A hair dryer assembly as set forth in claim 1 , wherein the body extends along an axis and is configured to direct the airflow out of the outlet in a first direction parallel to the axis of the body, and wherein the discharge housing is configured to redirect the airflow in a second direction perpendicular to the axis of the body such that the airflow is directed along a length of the hair positioned within the channel.

7. A hair dryer assembly as set forth in claim 6 , wherein the discharge housing further comprises ramps configured to direct the airflow through the discharge housing, wherein the ramps extend at angles relative to the axis of the body of the hair dryer.

8. A hair dryer assembly as set forth in claim 1 , wherein the body extends along an axis and wherein the channel extends along a channel axis perpendicular to the axis of the body.

9. A hair dryer assembly as set forth in claim 8 , wherein the discharge housing further comprises a top extending between the inlet end and the closed end, the channel wall extending downward from the top along the channel axis, wherein the channel wall is curved from the top and tapers radially inward relative to the channel axis.

10. An attachment for a handheld hair dryer, the attachment comprising:

an inlet end adapted for selective attachment to the handheld hair dryer, the inlet end defining an inlet for airflow to enter the attachment in a first direction;

a closed end opposite the inlet end;

a top extending between the inlet end and the closed end;

a bottom opposite the top;

a channel wall extending from the top toward the bottom and defining a hair receiving channel, wherein the channel wall extends continuously around the hair receiving channel such that hair within the channel is surrounded by the channel wall; and

an outlet for the airflow to exit the attachment, wherein the attachment is configured to direct the airflow through the outlet in a second direction perpendicular to the first direction and towards the hair within the channel.

11. An attachment as set forth in claim 10 , wherein the attachment further comprises a sidewall extending at least partly around the channel wall to define a space for the airflow to travel through the attachment.

12. An attachment as set forth in claim 11 , wherein the channel wall and the sidewall define the outlet.

13. An attachment as set forth in claim 12 further comprising a flow guide extending at least partly through the space and configured to direct the airflow towards the outlet.

14. An attachment as set forth in claim 10 , wherein the channel wall is curved from the top and tapers radially inward along the second direction.

15. An attachment for a handheld hair dryer assembly, the attachment comprising:

an inlet end adapted for selective attachment to the handheld hair dryer assembly, the inlet end defining an inlet for airflow to enter the attachment in a first direction;

a channel wall defining a hair receiving channel, wherein the channel wall extends continuously around the hair receiving channel such that hair within the channel is surrounded by the channel wall; and

an outlet for airflow to exit the attachment, wherein the channel wall is configured to direct the airflow through the outlet in a second direction perpendicular to the first direction and towards the hair within the channel.

16. An attachment as set forth in claim 15 further comprising a closed end opposite the inlet end, a top extending between the inlet end and the closed end, and a bottom opposite the top.

17. An attachment as set forth in claim 16 , wherein the channel wall extends from the top toward the bottom and is curved to funnel the hair into the channel.

18. An attachment as set forth in claim 15 further comprising a sidewall extending at least partly around the channel wall to define a space for the airflow to travel through the attachment.

19. An attachment as set forth in claim 18 , wherein the channel wall and the sidewall define the outlet.

20. An attachment as set forth in claim 19 further comprising a flow guide extending at least partly through the space and configured to direct the airflow towards the outlet.
