WIPO Patent Application WO/2015/155787
Kind Code:
A3
Abstract:
The method comprises wetting the stained area of the clothes with water, applying detergent at the stained area of the clothes and applying ultrasonic vibrations at the stained area of the clothes at a frequency range of 48 to 52 kHz with simultaneous application of water. The device (1) comprises a housing (2) bifurcated into a top portion (3) and a base portion ( 4) by a stained cloth access slot ( 5) extending horizontally in the housing. A cloth rest (12) is located on the base portion exposed in the access slot. An ultrasonic horn (17) is located in the top portion with the lower end thereof extending into the access slot and disposed above the cloth rest. The top portion has a water flow passage (19) opening to the cloth rest at the outlet end thereof. An ultrasonic generator (31) capable of generating ultrasonic vibrations in the frequency range of 48 - 52 kHz is connected to the ultrasonic horn through an ultrasonic drive.
