Abstract

Die Erfindung betrifft eine insbesondere in Kühltruhen angeordnete Vorrichtung zur Vernebelung kontinuierlich zulaufender Flüssigkeiten, insbesondere Wasser, mit einem Ultraschallschwinger (13), dessen Schwingfläche (13′) von einer Flüssigkeit überschichtet ist, und schlägt zur Erzielung einer verbesserten Wirksamkeit vor, daß die zu vernebelnde Flüssigkeit (F1) in der Vertiefung (V) einer auswechselbaren Wand (W) angeordnet ist, deren der Schwingfläche (13′) zugekehrte Wandungsabschnitt (12′) in Kontakt steht zu der die Schwingfläche (13′) überschichtenden, ausschließlich als Schallübertragungsmedium dienenden Flüssigkeit (F2). Auf diese Weise sind Verkrustungen am Ultraschallschwinger unterbunden. The invention relates in particular to freezers arranged device for nebulization continuously incoming liquids, especially water, with a Ultrasonic transducer (13), the vibrating surface (13 ') of is overlaid with a liquid and strikes to achieve an improved effectiveness that the nebulized Liquid (F1) in the recess (V) of an exchangeable one Wall (W) is arranged, the oscillating surface (13 ') facing wall section (12 ') is in contact with the the oscillating surface (13 ') overlaying, exclusively as Liquid (F2) serving as sound transmission medium. On this way there are incrustations on the ultrasonic transducer prevented.
