Description

Ultrasonic Cleaner {ULTRASONIC CLEANER}

The present invention relates to an ultrasonic cleaner technology, and more particularly, to an ultrasonic cleaner capable of improving cleaning efficiency by spraying high-temperature washing water upward and downward into an ultrasonic washing tank so that the washing water reaches an object to be washed evenly.

In general, washing of fruits or tableware is done manually by housewives, but recently, a dishwasher for automatically washing fruits or tableware has been developed and used.

The washing method of such a dish washing machine can be roughly classified into two.

The first is a nozzle-jet type washing method that sprays washing water at high pressure through a nozzle, and the second has a washing part called water for dishes inside the washing device. It can be divided into ultrasonic cleaning method to remove debris.

The cleaning method using the ultrasonic wave minimizes damage such as breakage or damage to the surface when washing materials such as vegetables or fruits with thin or not hard skins, and in the case of materials such as tableware, fine grooves or handle connections and It has the advantage of being able to wash in the same place.

When ultrasonic waves are generated in water, microbubbles are generated and then disappear due to vibration of sound waves, which is called cavitation.

When microbubbles are repeatedly generated and destroyed by cavitation, very high pressure and high temperature are accompanied. can be removed.

In relation to such an ultrasonic cleaning device, various technologies for improving cleaning efficiency are being researched and developed.
