The Fig. 1 shows a hand-held air shower 1 with an electric blower 2 and an arranged in a row electric heater 3 for generating an air flow 4 from a pipe section 5, the fan 2 are arranged in a housing section 6 and the heater 3 within the pipe section 5. On the housing portion 6, a control elements 7 (blower stage switch 26, heater level switch 27) exhibiting first handle 8 is arranged approximately at an angle of 90 degrees to the pipe section 5. The pipe section 5 is formed as a second handle 9, which has approximately the same diameter (dimensioning) as the first handle 8. Thus, when using the hand-held shower 1, these are optionally also held on the second handle 9, whereby an ergonomic improvement of the handling Hand air shower 1 is reached, which for example from the Fig. 2 to 5 evident.

The second handle 9 is thermally insulated (see also Fig. 9 ), whereby it can not heat up (cold grip area).

Alternatively or additionally, the pipe section 5 may be formed thermally insulated to the outside, whereby the second handle 9 can not heat.

The second handle 9 is designed like a cylinder, which results in a simple gripping and holding.

Optionally, the first and second handle 8,9, each with a non-slip surface 13 is provided. As a result, a secure grip when holding the handheld air shower 1 is achieved.

At the first handle 8, a first cold air switch 10 and the second handle 9, a second cold air switch 11 is arranged. The second cold air switch 11 is disposed in proximity 12 or within the housing section 6. This results in an ergonomic operation of the second cold air switch 11 also when holding the second handle 9. Preferably, the cold air switch 10,11 are provided as a push button 10,11. By actuating the respective cold-air switch 10, 11, a power supply of the heating device 3 is interrupted so that only the cold air 31 (FIG. Fig. 9 ) emerges from the fan 2 from the airflow outlet 35.

Fig. 2 shows a conventional handling position with the first handle 8 of a hand-held air shower 1 in an air flow treatment of hair of the head 14 of a rear hair area 14.1 by a barber 20th

Fig. 3 shows a common handling position on the first handle 8 a hand air shower 1 in an air flow treatment of top hair 14.2 by a barber 20. Here, the unfavorable arm posture of the hairdresser 20 is clear. In addition, in this case runs a power cord 25 unfavorable in the vicinity of the person 15th

Fig. 4 shows in difference after the Fig. 3 an ergonomic handling advantage of the hand-held air shower 1 by using a second grab handle 9 of the hand-held air shower 1. Here, the ergonomically favorable, low arm posture of the barber 20 clearly. In addition, this runs the power cord 25 cheaper away from the person 15.

1. 1. Beim Halten der Handluftdusche 1 am ersten Haltegriff 8 muss der rechte Arm 21 deutlich höher gehalten werden als der linke Arm 22 beim Halten der Handluftdusche 1 am zweiten Haltegriff 9.
2. 2. Durch einen größeren Abstand X1 zwischen einem Handgelenkpunkt 23 und einem Schwerpunkt 24 der Handluftdusche 1 ist ein Halten der Handluftdusche 1 erschwert. Außerdem ist ein gezielter Abstand zwischen einem Luftaustritt 25 und dem Kopfhaar 14 nur schwer kontrollierbar. Durch einen kleineren Abstand X2 zwischen einem Handgelenkpunkt 23 und einem Schwerpunkt 24 der Handluftdusche 1 ist ein Halten der Handluftdusche 1 ergonomisch vorteilhafter, wobei ein gezielter Abstand zwischen dem Luftaustritt 25 und dem Kopfhaar 14 besser kontrollierbar ist.

Fig. 5 shows an ergonomic difference in a self-handling handling with a hand-held air shower 1, which has a first and a second handle 8,9. This clearly shows two significant differences in the same positioning of the hand air shower 1 on the head hair 14:

1. 1. When holding the hand-held air shower 1 on the first handle 8, the right arm 21 must be kept significantly higher than the left arm 22 when holding the hand-held air shower 1 on the second handle 9.
2. 2. Due to a greater distance X1 between a wrist point 23 and a center of gravity 24 of the hand-held air shower 1, holding the hand-held air shower 1 is made more difficult. In addition, a targeted distance between an air outlet 25 and the head hair 14 is difficult to control. By a smaller distance X2 between a wrist point 23 and a center of gravity 24 of the hand air shower 1 holding the hand air shower 1 is ergonomically advantageous, with a targeted distance between the air outlet 25 and the head hair 14 is better controlled.

Fig. 6 shows in a side view a hand air shower 1 after the Fig. 1 but with a first cold air combination switch 16 disposed between the first and second handles 8, 9. As the first cold air combination switch 16, a push button switch 17 is provided here, which can be actuated either from the first or from the second grab handle 8, 9 with a finger (F1). This eliminates a second cold air switch 11th

Fig. 7 shows in a side view a hand air shower 1 after the Fig. 1 However, with a second cold air combination switch 16.1, which is arranged between the first and second handle 8,9. As a second cold air combination switch 16.1 here is a einschenkliger Tiltungswitch 18 is provided, which can be operated either from the first or the second handle 8,9 with a finger (F2, F3) can be. This eliminates a second cold air switch 11th

Fig. 8 shows in a side view a hand air shower 1 after the Fig. 1 However, with a third cold air combination switch 16.2 according to the invention, which is arranged between the first and second handle 8,9. As the third cold air combination switch 16.2 here a zweischenkliger (V-shaped) Tilting switch 19 is provided, which can be selectively operated from the first or the second handle 8,9 with a finger (F2, F3). This eliminates a second cold air switch 11th

In the Fig. 9 is opposite to the hand air shower 1 after the Fig. 6 a particularly advantageous hand air shower 1 shown, in which the second handle 9 remains particularly cool, that in the pipe section 5, a centrally arranged hot air duct 28 and a coaxial cold air duct 29 are provided. The central hot air duct 28 is formed by a hollow cylindrical tube 30 in which the heating device 3 is arranged. The coaxial cold air duct 29 is formed by the pipe section 5 and the central hot air duct 28. The central hot air duct 28 and the coaxial cold air duct 29 are acted upon by a cold air flow 31 of the blower 2, wherein a hot air flow outlet 32 from the central hot air duct 28 and from the coaxial cold air duct 29, a cold air flow 33 is effected by the heater 3, wherein the constant cold air flow 31 in the coaxial Cold air duct 29 causes a cool second handle 9.
