Warmlufthändetrockner mit temperaturgeregelter UmluftWarm air hand dryer with temperature-controlled circulating air
Gegenstand der Erfindung ist ein Warmlufthändetrockner, enthaltend ein Gebläse und ein elektrisches Heizelement. Das neue Gerät ist gekennzeichnet durch eine erhebliche Energieeinsparung, da nur die relativ geringfügige Menge hinzugemischter Außenluft aufgeheizt werden muß. Die vorgesehene Temperaturregelung der Umluft gestattet es, die Luft zu Beginn schnell aufzuheizen und auf einen für die schnelle und angenehme Trocknung der Hände günstigen Wert zu begrenzen.The invention relates to a hot air hand dryer containing a fan and an electrical heating element. The new device is characterized by considerable energy savings, because only the relatively small amount of outside air mixed in needs to be heated up. The intended temperature control of the circulating air allows the air to be heated up quickly at the beginning and at a rate favorable for quick and pleasant drying of the hands Limit value.
Die Vorteile des neuen Gerätes sind insbesondere:The advantages of the new device are in particular:
Da nur geringe Luftmengen aus der Umgebung eingemischt werden, ist es relativ leicht, die Umluft keimfrei zu machen, z.B. durch UV-Lampen oder durch elektrostatische Filter im Ansaugkanal (Abb. 1) der beizumischenden Außenluft.Since only small amounts of air from the environment are mixed in, is it is relatively easy to make the circulating air sterile, e.g. by using UV lamps or electrostatic filters in the intake duct (Fig. 1) the outside air to be mixed in.
Durch Führung der Umluft symmetrisch zu den Händen läßt sich die Trocknungszeit beträchtlich verkürzen, da die Luft nicht wie bei den marktüblichen Händetrocknern von einer Seite sondern gleichzeitig von allen Seiten auf die Hände geblasen wird. Zusätzlich kann durch Vorrichtungen zum Verwirbeln der Luft, die auf die Hände geblasen wird, die Trocknungszeit weiter verkürzt werden, da der Wärmeübergang auf die Hände mit zunehmender Verwirbelung wächst.By guiding the circulating air symmetrically to the hands, the drying time can be shortened considerably, since the air is not as with the usual hand dryers from one side but at the same time is blown on the hands from all sides. In addition, by means of devices for swirling the air that is on the hands is blown, the drying time can be further shortened, since the heat transfer to the hands with increasing turbulence grows.

Schnittbild T zeigt Luftführung im Händetrockner und seinen prinzipiellen Aufbau.Section T shows the air flow in the hand dryer and its basic structure.
Ein Motor mit Gebläse (1) an der Rückseite des Gerätes transportiert die Luft um einen Luftleitkörper (2) an den Außenwänden entlang. Dabei kommt die Luft vom Gebläse (1) zur Heizung (3), hin ter der ein Temperaturfühler (4) angebracht ist, der über eine geeignete Elektronik (5) die Lufttemperatur regelt.A motor with a fan (1) is transported to the rear of the device the air around an air deflector (2) along the outer walls. The air comes from the fan (1) to the heater (3) ter which a temperature sensor (4) is attached, which has a suitable Electronics (5) regulate the air temperature.
Bevor die zirkulierende Luft auf die Hände gelangt, kann sie durch geeignete Turbulenzerzeuger (6) verwirbelt werden, um dann in Kontakt mit den zu trockenden Händen zu kommen.Before the circulating air reaches the hands, it can pass through suitable turbulence generator (6) are swirled in order to then come into contact with the hands to be dried.
An der Wandseite des Gerätes wird zum Ausgleich der im Oberdruckgebiet (7) entwichenen Umluft von unten über ein Filtersystem (8) Außenluft in geringen Mengen in ein Unterdruckgebiet (9) über einen Kanal (10) angesaugt und er Umluft zugemischt. Diese angesaugte Außenluft dient gleichzeitig zur Motorkühlung.On the wall side of the device is to compensate for the high pressure area (7) circulated air escaped from below via a filter system (8) small amounts of outside air into a negative pressure area (9) via a Sucked in channel (10) and mixed in circulating air. This sucked in outside air also serves to cool the engine.
Ein berührungslos funktionierender Schalter (11) an sich bekannter Art kann an jeder Stelle im Gerät untergebracht werden, wo die gewünschte Wechsel richtung mit der angenäherten Hand eintritt.A contactlessly functioning switch (11) is known per se Art can be accommodated at any point in the device where the desired change direction occurs with the hand close to it.
Auf der Unterseite des Gerätes sind Löcher (12) so angebracht, daß dort kein nennenswerter Luftaustausch stattfinden kann, eingedrungenes Wasser jedoch ablaufen kann.On the underside of the device holes (12) are made so that no significant exchange of air can take place there However, water can run off.
Zum Abtöten oder Ausfiltern von noch in der Umluft befindlichen Keimen lassen sich im Luftstrom, z.B. vor dem Gebläse, Filter (13) oder UV-Lampen (14) anbringen.To kill or filter out germs that are still in the circulating air, filters (13) can be placed in the air flow, e.g. in front of the blower. or attach UV lamps (14).
