Are commercial ultrasonic dishwashers harmful to the human body?

Ultrasonic dishwasher is a kind of dishwasher technology. I don't know if you have used ultrasonic dishwasher. When you put your hand in, you will feel a tingling vibration. Will this feeling be harmful to the human body? This is a problem that many SHINELONG customers have worried about in the past. So today, I will give you a brief explanation through this sharing. Working principle of ultrasonic dishwasher Commercial ultrasonic dishwasher uses the cavitation effect, acceleration effect and straight flow effect of ultrasonic waves in liquids to convert energy through stainless steel conduction, converting sound energy into mechanical energy, and then the mechanical energy causes water to cavitation. In this process, the hand is not directly in contact with the ultrasonic wave, but with the cavitation bubbles, that is, water and mechanical energy are propagating, not sound waves. Therefore, from the working principle, commercial ultrasonic dishwashers will not directly cause harm to the human body. Safety frequency and power of ultrasonic dishwashers: The frequency of commercial ultrasonic cleaning is usually controlled at around 28KHz. This frequency belongs to the low-frequency part of ultrasound, with low power and low intensity, and is harmless to the human body. Noise problem: Although ultrasonic dishwashers will generate a certain amount of noise when working, this noise usually does not cause substantial harm to the human body. However, in order to reduce the impact of noise on users, you can choose an ultrasonic dishwasher with noise reduction design. Indirect contact: When using a dishwasher, users do not come into direct contact with ultrasonic waves, but through contact with washed dishes or water in the sink. Short contact time: When using an ultrasonic dishwasher, we usually put the dishes in the dishwasher to soak, and then take them out to the clean water tank for cleaning after soaking for a period of time. The time that the hands contact the ultrasonic water tank is very short. Precautions for use Although commercial ultrasonic dishwashers are harmless to the human body, you still need to pay attention to the following points during use: Avoid direct contact with high-temperature water: When the ultrasonic dishwasher is working, in order to further improve the cleaning effect, it will heat the water in the sink to a higher temperature. Therefore, when taking out the dishes or performing other operations, you should avoid direct contact with high-temperature water to prevent burns. Regular cleaning and maintenance: In order to maintain the good performance of the dishwasher and extend its service life, it should be cleaned and maintained regularly. This not only ensures the normal operation of the dishwasher, but also reduces the potential risks to the human body caused by dirt accumulation. Follow the instruction manual: Dishwashers of different brands and models may have different operating methods and precautions. Therefore, you should read the instruction manual carefully before use and operate according to the requirements in the manual. From the above, we can know that commercial ultrasonic dishwashers will not cause harm to the human body and can be used with confidence. Compared with the concern about whether ultrasonic waves will cause harm to the human body, noise may be a more concerning issue. Ultrasonic dishwashers use high-frequency vibrations, which inevitably cause certain noises. At present, the market has gradually been replaced by hood-type dishwashers and Changlong dishwashers, and ultrasonic dishwashers are currently more used as pre-cleaning accessories for other commercial dishwashers.
