METHOD OF ULTRASONIC DRYING OF LINEN IN TUMBLER WASHING MACHINES Russian patent published in 2006 - IPC D06F58/02 

FIELD: washing machines.

SUBSTANCE: according to proposed method, after preliminary removal of moisture by centrifuging, linen is acted upon by elastic vibrations of ultrasonic frequency. Said vibrations are formed by aerodynamic or electromechanical converters and are introduced into linen to be dried contactlessly through nonresonance air gaps or through design members of washing machine. Intensity of elastic vibrations is set within 135 and 160 dB. Frequency of vibrations is chosen to provide acoustic resonance of inner volume of washing machine tumbler and/or inner air gap between tumbler for linen and outer tumbler. In process of drying frequency is changed according to change in quantity of linen to be dried and its moisture content. Owing to use of optimum sources of ultrasonic vibrations and corrected parameters and conditions of formation and introduction of vibrations into linen, energy consumption for implementing the method is reduced.

EFFECT: reduced energy consumption.
