What is the principle of an ultrasonic dishwasher?

Ultrasonic dishwashing is super clean, using ultrasonic technology to shake off stains, and the effect of sterilization, there should be no dishwasher on the market that can compare the effect with ultrasonic, I like small and delicate dishwashers, Midea's recently launched new freestanding dishwasher is very good, you can also go and see.

Ultrasonic waves propagate in the liquid, so that the liquid and the cleaning tank vibrate together at the ultrasonic frequency, and the liquid and the cleaning tank vibrate with their own natural frequency, which is the frequency of sound waves, so people hear the buzzing sound. With the continuous development of the cleaning industry, more and more industries and enterprises have used ultrasonic cleaning machines.

The high-frequency oscillation signal sent by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagated to the medium cleaning solvent, and the ultrasonic wave radiates forward in the cleaning liquid, so that the liquid flows and produces tens of thousands of tiny bubbles with a diameter of 50-500 m, and the tiny bubbles existing in the liquid vibrate under the action of the sound field. These bubbles form and grow in the negative pressure area where the ultrasonic wave propagates longitudinally, while in the positive pressure area, when the sound pressure reaches a certain value, the bubble increases rapidly and then closes abruptly. And when the bubble closes, a shock wave is generated, thousands of atmospheres are generated around it, destroying the insoluble dirt and dispersing them in the cleaning solution, when the group particles are wrapped in oil and adhere to the surface of the cleaning parts, the oil is emulsified, and the solid particles are separated, so as to achieve the purpose of cleaning parts purification.

In this process, known as the "cavitation" effect, the bubble closes to form instantaneous high pressures of several high temperatures and more than 1,000 atmospheres.

The advantages of the ultrasonic cleaner are: the ultrasonic cleaning effect is good, and the operation is simple. The sound that people hear is a sound wave signal with a frequency of 20-20000Hz, and the sound wave above 20000Hz is called ultrasound, and the transmission of sound waves travels longitudinally according to a sinusoidal curve, producing a large number of small bubbles.

One reason is that the tensile stress in the liquid forms a negative pressure, and the decrease in pressure makes the gas originally dissolved in the liquid supersaturated, and escapes from the liquid to become small bubbles; Another reason is that the strong tensile stress "tears" the liquid into a cavity, which is called cavitation.

Actually, I can't understand it, I looked for it.

Xi'an Kuaijie Dishwasher Co., Ltd. is the first ultrasonic manufacturer in Shaanxi, which can be searched on the Internet. Last month, their salesman came to sell, because I didn't use it, I don't know how to buy it, and then I went to their company and experimented with it. Not bad.

I bought one and have been using it ever since. Pretty good.

The ultrasonic dishwasher can not only wash dishes but also crayfish, which is very convenient, I bought one from Glacous last year, and it is very cost-effective.

The dishwasher of Glacos Cos looks really beautiful in appearance, and the dishwasher prepared now can wash vegetables and fruits, wash pots, and the large-capacity is very practical, and the cost performance is very high.

I think the kgw dishwasher is quite easy to use, convenient, fast, and can wash anything. Save water and electricity. I bought another brand of dishwasher before, it was too troublesome to use, my mother didn't like it, and now I changed the kgw sink dishwasher, and my family said that it was very good.

Our ultrasonic dishwasher used in the staff canteen of Meilan Group in 2005, 28,000 times per second oscillation blasting, constant efficiency, is a real standard ultrasonic dishwasher, ten years as a day, stable working state, high cleaning efficiency, R & D and production in 2002, have been used so far.

The real standard ultrasonic dishwasher, ten years as a day, stable working state, high cleaning efficiency, 2002 research and development and production so far, the use of all said good.

Oubeili, innovative research and development, specializing in the production of ultrasonic dishwashers for 15 years, the representative customer Zhongnanhai uses more than 20 ultrasonic dishwashers, pure physical cleaning, without any chemical residue. Whether the ultrasonic dishwasher is good or not, depending on whether the cleaning technology is passed, mastering the core technology is the king, and the consumer feels very important.

Kingroad, Bangjie, the country is doing better.

In fact, what brand is better than bad, just compare it more, you can search for KGW ultrasonic dishwashers, and then compare and look at other brands, and then make a decision!

For commercial use, Chengdu Jinyu ultrasonic dishwasher is OK and can meet the needs of dishwashing.

The brand's dishwasher is practical:

After the advent of dishwashers, people's lives have been greatly improved, allowing people to get rid of the tedious household chores of washing dishes, and the quality of life has improved a lot. However, dishwashers are not as widely used as washing machines, and the reason is that some people are worried that dishwashers are not practical and cannot get the desired results after spending more money.

The relevance is as follows. Today, through a detailed and comprehensive introduction, I will tell you whether the dishwasher is really practical. To be able to wash "everything" is to be practical, to judge whether the dishwasher is really practical, first of all, you have to see whether it can clean the dishes, or whether it is cleaner than hand washing. Some low** small brand dishwashers.

Because the technology is not up to standard, ordinary dishes can't be cleaned, let alone those special-shaped dishes. There are also some dishwashers that can be cleaned even though some dishes can be cleaned, but every time there are "fish that slip through the net", sometimes the next time you use it, you find that there are a few dishes with dried grease residues!

Such a dishwasher, of course, is not practical.

And big brand dishwashers like Robam Appliances will not have the above problems. Take Robam Power Dishwasher WB721 as an example, it uses an extended double-layer spray arm, 360° cyclone flushing without cleaning dead ends, high-temperature hot water thoroughly washes heavy oil and heavy pollution, and the heavy oil stains left by Chinese-style stir-fried dishes can be easily handled.

Moreover, the "strange-shaped" special-shaped dishes can also be thoroughly washed, which is cleaner than hand washing, which is more labor-saving and time-saving, and such a product is naturally very practical. Can disinfect and sterilize to protect the health of the whole family, is it more practical, is the dishwasher really practical? After this epidemic incident, many people pay more attention to the hygiene of tableware.

Some dishwashers do not have a sterilization and disinfection effect, and you have to buy another disinfection cabinet after buying it, so such a product may not be very practical.

It's very easy to use. The sink dishwasher integrates the common sink and the dishwasher, and has the functions of heating to remove grease, ultrasonic to remove pesticides, and water to remove food residues, but it also has disadvantages.

1. Advantages: It does not take up space, and the kitchen sink can be modified directly, so that the kitchen sink can be changed to a dishwasher, so it is better to save space, which is very suitable for the kitchen area of every inch of land.

Especially some old house renovations, the sink dishwasher is still very good, the area is not enough, and you don't want to renovate the kitchen, then install a sink dishwasher! Of course, in addition to this advantage, the sink dishwasher, washing capacity, and power consumption are very good.

2. Disadvantages: The biggest disadvantage of the sink dishwasher is the poor drying ability, the space of the sink dishwasher to accommodate the dishes and chopsticks is relatively small, and the sink area is relatively small, which cannot be compared with the built-in and freestanding dishwashers, so the sink dishwasher is still much worse than the built-in in terms of drying performance and washing quantity.

I also have an ultrasonic sink at home, and the upstairs is a brand, called kgw, and it is very easy to use! All kinds of washing every day, fast time, labor-saving, trouble-free! It's that I don't know how to tune the drainer, after the boss taught me, I glued it on the screws, and now it's very worry-free!

The effect of ultrasonic dishwashing is okay, and the effect of washing vegetables is better, which can remove pesticide and fertilizer residues in fruits and vegetables, blood stains and grease in meat, mud and parasites in seafood.

Take Kang World as an example, the original frequency conversion technology can be cleaned faster and cleaner, and when washing the nails, a cloud of dirt will gush out in an instant!

The ultrasonic sink is very easy to use, there is no excess structure inside, it is easy to clean, and you can put a lot of dishes and chopsticks at a time, you don't need to place it for cleaning, you can also wash all kinds of vegetables and fruits together, you can also wash teacups and tea stains, range hoods, etc., and it is no problem to turn on the machine for a day! My friends and I both have the brand of KGW ultrasonic sink, you can search for it.

Very easy to use, our home has a house called kgw ultrasonic sink, the workmanship is very good, the dishes and chopsticks do not need to be placed in it can be washed, you can also wash a lot of dishes and chopsticks, the power is very small, some old oil stains can be done in 30-45 minutes, you can also wash as long as you want, wash for a day is fine!

It's like other brands that can only be open for 10 minutes at a time!

The ultrasonic sink dishwasher is a new product that has emerged by adding ultrasonic cleaning technology to the original dishwasher. With the continuous development and maturity of ultrasonic cleaning technology, industrial precision cleaning has gradually entered the household field. Ultrasonic cleaning ushered in the era of household use.

Compared with the original dishwasher, the ultrasonic sink dishwasher not only absorbs the technical advantages of large capacity, high efficiency, high temperature cleaning, high temperature drying, etc., but also uses the cavitation effect of ultrasonic waves to clean tableware and fruit and vegetable ingredients without dead ends, and truly realizes thorough cleaning. So ultrasonic sink dishwasher is the development direction of dishwashers, welcome to understand!

There are many styles of dishwashers, and you need to choose carefully when buying. What are the principles of ultrasonic dishwashers? PChouse will take you to find out.

Ultrasonic dishwashers use the principle of ultrasonic atomized ion cleaning. When ultrasonic waves pass through a liquid medium, the liquid medium vibrates at a higher frequency, causing the liquid molecules to produce alternating positive and negative shock waves. When the sound intensity reaches the value, the rapid growth and instantaneous strong closure of the tiny cavitation bubbles in the liquid produce strong microwaves and shock waves, which destroy the dirt on the surface of the object to be cleaned and fall off from the surface to be cleaned.

Although each cavitation bubble has no significant effect, there are hundreds of millions of cavitation bubbles in action every second, which has a good cleaning effect.

The working principle is to use the direct and indirect effects of ultrasonic wave on the liquid and dirt by the cavitation, acceleration and direct flow of ultrasonic waves, so that the dirt layer is dispersed, emulsified and peeled off to achieve the purpose of cleaning.

Ultrasonic dishwashers consist of an ultrasonic generator and an ultrasonic energy exchange cleaning tank. Clean disposable cutlery, cutlery, glasses, spoons, chopsticks, cutlery inside the restaurant. The generator outputs the power of ultrasonic oscillation, and the electrical energy is replaced by the transducer instead of the ultrasonic mechanical vibration.

Under the action of ultrasonic vibration, the cleaning liquid generates micro-nucleus waves with tens of millions of atmospheres, forming a high-speed nuclear gas flow between the liquid surface and the cleaning surface, so that all kinds of dirt adhered to the cleaning surface can be peeled off, so as to achieve the purpose of cleaning. The use of ultrasonic cleaning, with the advantages of fast cleaning speed, no damage to parts, etc., reduce labor intensity, save costs.

1. Cleaning tableware: under the action of ultrasonic, the cleaning solution produces a large number of bubbles, and with the vibration, peel off the dirt on the surface of the tableware, or make the oil cracks out of the gaps, so that the bubbles can drill into the voids, impact the dirt, and finally achieve the purpose of removing the dirt from the ridge.

2. Washing vegetables and fruits: Ultrasonic dishwashers can be used to wash vegetables and fruits, I believe many people don't know. Every day, as long as the fruits and vegetables that need to be washed are ready, put them in the bowl rack, press the start button, and the washing program can be completed in about 7 minutes.

3. Sterilization and disinfection: The dishwasher can not only clean the tableware, vegetables and fruits, but also remove viruses and bacteria on its surface. It is believed that if the bacteria on the tableware, vegetables and fruits are killed, it is believed that the probability of people getting sick will be reduced.

Compared to conventional dishwashers, ultrasonic dishwashers do not require motors and water pumps and operate quite quietly. If you like a quiet home environment, you should buy this.

1. High cleanliness.

It is characterized by high cleanliness and no dead ends. This is because ultrasonic dishwashers use the high-frequency vibration of water molecules to clean dishes, so it has a very high degree of cleaning, and there are no dead spots that cannot be washed, which is very suitable for Chinese families.

2.Save water and electricity.

Because ultrasonic dishwashers do not require motors and water pumps in use, and do not need a water circulation system during washing, all operations are completed by the vibration of water molecules, so they can save water and electricity in use.

3.Simple washing.

Traditional dishwashers mainly rely on the chemical action of detergent to clean the dishes, while ultrasonic dishwashers do not require detergent. If detergent is added, it only plays an auxiliary role. Ultrasonic dishwashers have no special requirements for detergents.

4.Long life.

Because ultrasonic dishwashers use the vibration of water molecules for cleaning, they do not need a water stirring mechanism like traditional dishwashers, nor do they need motors, pumps and other systems, so the structure is very simple, so the probability of failure is very small, so the service life can be guaranteed.
