Abstract

The invention discloses a multifrequency phased ultrasonic clothes cleaning and dehydration method and device, wherein the device comprises a clothes washing box, a circuit control system, a water inlet and drain device, a display control panel, ultrasonic phased-arrays and an air exchange device, wherein an acoustic wave baffle board is arranged in the clothes washing box, and floats on the liquid surface when working; the ultrasonic phased-arrays are uniformly distributed on the side wall and the bottom part of a barrel; the clothes washing box is provided with a water inlet device at the top part and a drain device at the bottom part; the ultrasonic phased-arrays comprise ultrasonic phased-arrays of different resonant frequencies. The invention finishes full ultrasonic clothes washing by using the method combining high and low frequency ultrasonic according to different characteristics of the cleaning and the dehydration processes in the washing process, that is to say, low frequency ultrasonic is used for cavitation cleaning, and the high frequency ultrasonic is used for atomization dehydration. The invention utilizes the method of scanning with ultrasonic beams so that the energy of the ultrasonic is more concentrative, the penetrating power is stronger, the washing and the dehydration effects are more uniform, and both the cleanness and the dehydration rate are improved.

Description

technical field [0001] The invention belongs to the technical field of ultrasonic laundry, and in particular relates to a method and a device for cleaning and dehydrating clothes by using high and low frequency phased array transducers to realize partial concentration of ultrasonic energy. Background technique [0002] Washing machines are currently divided into two categories: mechanical and non-mechanical. Among them, the mechanical type is divided into a wave plate type, a drum type, etc., and generally the rotating wheel drives the water flow or the rolling operation generates friction for washing. The wave plate type has a simple structure and low cost, but the wear rate is high; the drum type has high cleanliness, but the cost is high. The mechanical type has common disadvantages. It is easy to twist the clothes together during the long-term operation, and the friction will damage the clothes. After washing, the clothes will be wrinkled, deformed or even damaged, and ...
