Abstract

A handheld hair dryer includes a body extending about an axis. The body includes an inner wall and an outer wall. The inner wall and the outer wall define a cavity therebetween. A central passage is defined by the inner wall. The handheld hair dryer also includes an inlet and an outlet. The inlet is defined by the inner wall and is in flow communication with the central passage to allow airflow in the central passage to be drawn into the cavity through the inlet. A fan is configured to draw the airflow through the inlet and direct the airflow through the cavity towards the outlet. The handheld hair dryer further includes a handle connected to the body.

Claims (34)

1. A handheld hair dryer comprising:

a body extending about an axis, the body including an inner wall and an outer wall spaced radially outward from the inner wall, the inner wall and the outer wall defining a cavity therebetween, wherein a central passage is defined by the inner wall;

an inlet defined by the inner wall, wherein the inlet is in flow communication with the central passage to allow airflow in the central passage to be drawn into the cavity through the inlet;

an outlet for the airflow to exit the cavity, wherein the hair dryer is configured to direct the airflow through the cavity and towards the outlet;

a fan positioned adjacent the inner wall, wherein the fan is configured to rotate about an axis perpendicular to the axis of the body; and

a handle connected to the body.

2. A handheld hair dryer as set forth in claim 1 , wherein the fan includes a hub and a plurality of blades extending from the hub, and wherein the blades are configured to direct air in a radial direction relative to the rotation axis of the fan.

3. A handheld hair dryer as set forth in claim 2 , wherein the fan is positioned above the handle and is configured to direct airflow towards the cavity.

4. A handheld hair dryer as set forth in claim 1 , wherein the fan is coupled to a motor within the handle.

5. A handheld hair dryer as set forth in claim 1 , wherein the outer wall and the inner wall extend from a first end of the body to a second end of the body, the inlet being defined by the inner wall intermediate the first end and the second end.

6. A handheld hair dryer as set forth in claim 5 , wherein the central passage extends from the first end to the inlet, and the hair dryer is configured to draw airflow into the inlet from the central passage.

7. An air-moving appliance comprising:

a body extending about an axis, the body including an inner wall and an outer wall spaced radially outward from the inner wall, the inner wall and the outer wall extending along a central axis and defining a cavity therebetween, wherein a central passage is defined by the inner wall;

an inlet defined by the inner wall, wherein the inlet is in flow communication with the central passage to allow airflow in the central passage to be drawn into the cavity through the inlet;

a fan positioned adjacent the inner wall, wherein the fan is configured to rotate about an axis perpendicular to the axis of the body;

an outlet for the airflow to exit the cavity, wherein the fan is configured to direct the airflow through the cavity and towards the outlet;

a handle connected to the body; and

a motor positioned at least partly within the handle and coupled to the fan.

8. An air-moving appliance as set forth in claim 7 , wherein the fan includes a hub and a plurality of blades extending from the hub, and wherein the blades are configured to direct air in a radial direction relative to the rotation axis of the fan.

9. An air-moving appliance as set forth in claim 7 , wherein the fan is positioned above the handle.

10. An air-moving appliance as set forth in claim 7 , wherein the outer wall and the inner wall extend from a first end of the body to a second end of the body, the inlet being defined by the inner wall intermediate the first end and the second end.

11. An air-moving appliance as set forth in claim 10 , wherein the central passage extends from the first end to the inlet, and wherein the air-moving appliance is configured to draw airflow into the inlet from the central passage.

12. A handheld hair dryer comprising:

a body extending about an axis, the body including an inner wall and an outer wall spaced radially outward from the inner wall, the inner wall and the outer wall defining a cavity therebetween, wherein a central passage is defined by the inner wall and extends from a first end of the body to a second end of the body;

an inlet for airflow to enter the cavity;

an outlet for the airflow to exit the cavity;

a shield coupled to the inner wall at a location between the outlet and the inlet and configured to extend across the central passage and direct airflow toward the inlet; and

a handle connected to the body.

13. A handheld hair dryer as set forth in claim 12 , wherein the outer wall and the inner wall extend from the first end to the second end, and wherein the inner wall defines the inlet intermediate the first end and the second end.

14. A handheld hair dryer as set forth in claim 12 , wherein the shield includes a transparent material.

15. A handheld hair dryer as set forth in claim 14 further comprising a light configured to illuminate the shield.

16. A handheld hair dryer as set forth in claim 15 , wherein the light is configured to change color based on an operational status of the hair dryer.

17. A handheld hair dryer as set forth in claim 12 , wherein the shield includes a logo.

18. A handheld hair dryer as set forth in claim 12 , further comprising a fan positioned adjacent the inner wall, wherein the fan is configured to rotate about an axis perpendicular to the axis of the body.
