Definitions

• the invention relates to a hand dryer having an externally accessible drying chamber, a blower and a plurality of discharge nozzles, which is joined to the fan ⁇ and are oriented such that in the Trock ⁇ drying space a drying operation is executable.
• Such a hand dryer is known for example from the manufacturer "Dyson” model "Airblade".
• the beispielshal ⁇ over specified hand dryer according to the prior art is one which carries out a drying process with high air velocity. Depending on the manufacturer, this air speed can be more than 600 km / h. The air of high speed is blown on the hands, so that on the hands of water is stripped off. A heating of the air by heating elements is not required for this drying effect, but can be integrated if necessary. In these hand dryers, the drying room is accessible only from above, the
• Outlet nozzles are aligned substantially horizontally. Due to the determined by the discharge nozzles scraping plane of the hand dryer in a horizontal or slightly inclined to the user's direction, the hands must be guided from above through the stripping level in the drying room. In Einhal ⁇ tung an ergonomic inclination of the wrist, it is necessary for this, the elbow in the use of the hand dryer is located at a distance above an insertion slot to platzie ⁇ ren. A gripping area of the hand dryer and the drying ⁇ space inside the device and is only visible from above. Therefore, users may be inhibited from reaching into the loud-working and highly tactile device on the fingers. This can cause discomfort to users of the hand dryer.
• the aforementioned, known hand dryer is closed trough-shaped down, which promotes the accumulation of foreign bodies and liquids. Also, the drying room is difficult to clean due to the narrow opening upwards. Based coating ge and contamination possible consequences that can lead to Geruchsbeläs ⁇ adjustments or to a biologically active load of the room air.
• hand dryers that operate at high air speeds are rather large-volume and cover a large floor area with the usual wall mounting. It is also necessary in these devices to redirect sucked air in a deflection angle between 90 ° and 180 °, since the air is drawn in ⁇ half of the stripping, conveyed up and then blown in a substantially horizontal stripping direction on the discharge nozzles.
• the object of the invention is to further develop the hand dryer mentioned above in such a way that its ease of use is increased.
• the housing has at least two gageinan ⁇ the arranged housing parts, between which the drying chamber is arranged and in the vertical
• the at least two housing parts have the discharge nozzles, which are arranged one above the other such that an air flow plane spanned by them extends predominantly vertically.
• the hand dryer Due to the vertical arrangement of at least two housing parts next to each other, the hand dryer is open both up, down and forward, so that compared to the devices of the prior art results in a more variable use. People of different sizes can easily insert their hands into the drying room and use the hand dryer. Since the hand dryer is open at the bottom, stripped liquid does not collect in the device itself, so that any foreign body and stripped liquid ⁇ speeds can run downwards. This effectively counteracts contamination or microbial contamination of the device interior.
• the at least two housing parts can be tubular etcbil ⁇ det and on their, the drying space facing sides of the blow-off nozzles have.
• the hand dryer takes up very little space, while still effective drying can be achieved.
• tubular housing part which is arranged vertically between the superbs ⁇ least two housing parts and having discharge nozzles on both sides.
• the hand dryer can be arranged in this embodiment, in each case a hand of a person between the other, arranged in the middle, rohrförmi- gene housing part and one of the two outer housing parts, so that each hand is acted upon from the right and left with air. This promotes the effectiveness of
• Housing parts be trough-shaped, in which case the discharge nozzles are arranged at their front edges. In this case, stripped liquid is blown from the side against the tub-shaped housing parts and can then be discharged down from the hand dryer.
• a further housing part may be arranged, which is tubular and on both sides in the direction of each one of the at least two
• Housing parts directed exhaust nozzles has. This results in the advantage that each individual hand of a peson can be acted upon by air from both sides, so that the drying process is done quickly.
• the fan may be formed as a separate component ⁇ and be removed from the at least two housing parts at ⁇ sorted. It is possible that the blower is mounted above ⁇ half, below or next to the discharge nozzles. This can be realized a significant reduction of the covered by the hand dryer ⁇ floor area.
• egg ⁇ ner arrangement of the fan in extension of a feed to the discharge nozzles and behind a mounting wall can be expected with a deflection of the air at an angle of 0 ° to 90 °. This low deflection internal losses in the promotion of the air current are reduced and noise development ⁇ reduced.
