Working Principle Of Ultrasonic Dishwasher
Mar 01, 2025| The working principle of ultrasonic dishwasher is mainly based on the ultrasonic cavitation effect, which achieves efficient cleaning through high-frequency vibration and the rupture of tiny bubbles. The following is a detailed analysis of its working principle:
"Ultrasonic vibration"
Ultrasonic dishwasher generates high-frequency oscillation signals through ultrasonic generators, which are converted into high-frequency mechanical vibrations through transducers and transmitted to the liquid medium (usually water). This vibration causes the liquid molecules to produce positive and negative alternating shock waves.
"Formation and rupture of cavitation bubbles"
When the sound intensity of ultrasonic waves reaches a certain value, a large number of tiny cavitation bubbles will grow rapidly in the liquid. These bubbles expand rapidly and close instantly under the action of ultrasonic waves, producing strong micro-explosions and shock waves. This cavitation effect can destroy the dirt on the surface of tableware and make it fall off the surface.
"Cleaning effect"
Although the effect of a single cavitation bubble is limited, there are hundreds of millions of bubbles working every second, so ultrasonic dishwashers can achieve efficient and dead-angle cleaning. It is particularly suitable for removing difficult-to-wash stains such as rice grains, oil stains, smoke stains, and tea stains.
Advantages and Features
Power saving: Ultrasonic dishwashers do not require motors and water pumps, and consume low power.
Water saving: Only a small amount of water is needed during the cleaning process.
Low noise: Compared with traditional dishwashers, ultrasonic dishwashers are quieter.
Adaptability: It can clean tableware of various shapes, including irregular-shaped dishes.
Summary: Ultrasonic dishwashers achieve efficient cleaning through the ultrasonic cavitation effect, with the advantages of power saving, water saving, and low noise. It is an environmentally friendly and practical household appliance.
