How to choose an ultrasonic dishwasher

1. Look at the brand: The quality of ultrasonic dishwashers from different brands is different. Generally, the quality of products from big brands is better. Therefore, it is recommended to give priority to well-known brands when purchasing dishwashers.

2. Look at the appearance: No matter what kind of defective product you buy, looking at the appearance is also one of the ways to measure its quality. Usually, check whether the product looks good, whether there are dents, scratches, and whether there are burrs on the corners. If there are burrs, it is recommended not to buy it to avoid buying inferior products.

3. Check the performance: A dishwasher with good performance will not have any abnormalities during use and has a long service life. When purchasing, you should test it with power on to ensure that there are no abnormalities in the function keys and that the machine runs smoothly throughout the process.

4. Look at after-sales service: Since ultrasonic dishwashers are relatively expensive, the after-sales service of the product must be good. Usually, the product can be repaired for free within one year from the date of purchase. If the product is produced by a manufacturer with poor after-sales service, there is not much difference between having a warranty and not having a warranty, so you must buy products from manufacturers with good after-sales service.

What is the principle of ultrasonic dishwasher

The principle of ultrasonic dishwasher is that high-frequency sound waves make liquid vibrate to achieve the cleaning effect. When ultrasonic waves pass through the liquid medium, they force the liquid medium to vibrate at an extremely high frequency, causing the liquid molecules to produce positive and negative alternating shock waves. When the sound intensity reaches a certain value, tiny cavitation bubbles are generated in the liquid and burst instantly, generating strong micro-explosions and shock waves that destroy the dirt on the surface of the object being cleaned and fall off the surface of the object being cleaned. Although the effect of each cavitation bubble is not great, there are hundreds of millions of cavitation bubbles at work every second, which has a very good cleaning effect. Because ultrasonic waves can penetrate solid matter and make the entire liquid medium vibrate and produce cavitation bubbles, there is no dead corner that cannot be cleaned with this cleaning method.

What are the ways to maintain a dishwasher?

1. The filter in the dishwasher water tank is prone to accumulate vegetable leaves and other debris. It needs to be cleaned regularly to prevent clogging.

2. Residues are also easy to accumulate inside the spray pipe. It is best to disassemble and clean it to prevent blockage.

3. The water suction cylinder is located at the inlet of the water pump. Pay attention to cleaning at ordinary times to avoid the water suction effect of the water suction cylinder to deteriorate.

4. Clean the air inlet of the air pump regularly, because the air inlet will be blocked by dust and oil.
