Are ultrasonic dishwashers harmful to the human body?

2025/01/17

Ultrasonic dishwashers are a type of dishwasher commonly used in the catering industry. Many people will be more or less surprised by the strange vibration and numbness when they use ultrasonic dishwashers for the first time, and worry about whether ultrasonic dishwashers are harmful to the human body. So today, SHINELONG editor will analyze it in detail for everyone. First of all, here is a conclusion: ultrasonic dishwashers will not harm the human body. What is ultrasound? The working principle of ultrasonic dishwashers Ultrasonic waves are a mechanical wave with a very short wavelength. We all know that sound is generated by vibration, and ultrasonic waves are also a kind of sound. It’s just that the word "super" in ultrasonic waves comes from the lower limit of its frequency band exceeding human hearing. It is precisely because it exceeds human hearing that ordinary people cannot hear it (the noise of ultrasonic dishwashers is generated by the vibrator vibrating the stainless steel plate. The frequency of some sound waves generated by this is within the human hearing range, so noise can be heard, but it should be noted that the noise heard at this time is not ultrasonic). Ultrasonic waves have mature applications in the market, such as inspection, processing, cleaning, research, medicine, industrial control, pharmaceuticals, aging, dispersion, etc. Among them, ultrasonic dishwashers use the cleaning ability of ultrasonic waves. Ultrasonic dishwashers generate ultrasonic waves through high-frequency vibration of the vibrator. When the ultrasonic waves are transmitted to the dishes we need to clean through water, the high-frequency ultrasonic vibration will cause the water to produce rapidly growing tiny cavitation bubbles and burst strongly, so that the dirt on the dishes is destroyed and falls off. Is ultrasonic dishwasher harmful to the human body? When we use ultrasonic dishwashers, we will feel a strong vibration and numbness. When we first contact with them, many people will feel frightened or uncomfortable. Many people will worry that ultrasonic dishwashers are harmful to the body. In fact, through the above principle of ultrasound, we can know that this strong vibration and numbness are mainly caused by overclocking vibration and the violent generation and explosion of tiny cavitation bubbles. The qualified and compliant ultrasonic dishwashers on the market will be tested by national testing agencies. The ultrasonic energy generated is far from harmful to the human body. The inferior ultrasonic dishwasher cannot even produce the effect of violent cavitation bubbles, let alone harm the human body. Through the above introduction, I believe that everyone has already understood whether ultrasonic dishwashers are harmful to the human body. If you have a need for ultrasonic dishwashers, you may wish to consult SHINELONG. We will recommend a suitable ultrasonic dishwasher model for you according to your actual situation.
