## Abstract

Hand-held hair dryer having a housing provided with air inlet, an electric fan, and power supply. The hair dryer is provided with an upper air outlet and a lower air outlet extending substantially in opposite directions out from the housing and provided with heating element. The lower air outlet also serves as a grip. The housing is provided with a throttle arranged pivotably about a pivot. The throttle is operated by a button between a first position where the upper air outlet is blocked and the lower air outlet is open to air flow, and a second position where the air flows in a direction opposite of the first.

## Claims

### Claim 1

Hand-held hair dryer comprising:
an air supply device;
opposing upper and lower air outlets;
air flow and air temperature control devices;
at least one heating element for heating air;
a guiding device arranged at the air supply device for directing air flow to either the upper or lower air outlets by means of an air flow direction control device;
wherein said upper and lower air outlets are substantially perpendicular to the air supply device; and
a grip located on at least one of the upper and lower air outlets so that the hair dryer can be held by the upper and lower air outlets.

### Claim 2 (depends on 1)

The hair dryer of claim 1, wherein the guiding device for directing air flow comprises a throttle pivotally connected to the air supply device and connected operatively with an actuator for pivoting the throttle to a position blocking the air flow to the upper air outlet, and opening the air flow to the lower air outlet, and vice versa.

### Claim 3 (depends on 1)

The hair dryer of claim 1, wherein the grip is integral with the lower air outlet and wherein the grip is provided with a heat insulating material.

### Claim 4 (depends on 3)

The hair dryer of claim 3, wherein the air flow direction control device is arranged at an upper part of the combined lower air outlet and grip.

### Claim 5 (depends on 1)

The hair dryer of claim 1, wherein the air flow is produced by a fan driven by an electric motor integral with the hair dryer powered by electricity from a power outlet via a cable, wherein the cable is arranged in a holding device connected pivotally to the hair dryer housing in a vertical direction.

### Claim 6 (depends on 1)

The hair dryer of claim 1, wherein at least a part of the grip is provided with a surface having increased friction.

### Claim 7 (depends on 1)

The hair dryer of claim 1, wherein the upper and lower air outlets are arranged in a mutual angle of about 165°.

### Claim 8 (depends on 1)

The hair dryer of claim 1, wherein the upper and lower air outlets are arranged in a mutual angle of about 180°.

### Claim 9 (depends on 2)

The hair dryer of claim 2, wherein the throttle is arch-shaped so that when the throttle is in an operating position, the throttle forms an arch-shaped channel from the air supply device to the respective upper and lower air outlet.

### Claim 10 (depends on 1)

The hair dryer of claim 1, wherein the heating element is connected to the air supply device.

### Claim 11 (depends on 1)

The hair dryer of claim 1, wherein heating elements are provided in each of the upper and lower air outlets.

### Claim 12 (depends on 1)

The hair dryer of claim 1, wherein a longitudinal axis of the upper and lower air outlets is substantially perpendicular to a longitudinal axis of the air supply device.
