Description

ULTRASONIC WASHER HAVING AN IMMERGING DEVICE CAPABLE OF IMMERGING A WASHED OBJECT}

In general, the sound frequency that humans can hear is in the range of 20 to 20000 Hz, and the frequency is more than 20000 Hz. The history of the use of ultrasound originated in 1916 when French physicist P. Langseuven developed a sonar, an ultrasonic sonar, to detect submarines. The ultrasonic application device around the living room is an ultrasonic cleaner used in a clock shop, an optician or a restaurant. The ultrasonic cleaner vibrates the cleaning liquid with ultrasonic waves to wash away dust, oil, rust, and even food waste.The ultrasonic cleaning method has a short washing time compared to other cleaning methods and has the advantage of relatively cleansing foreign substances. It is used.

In addition, humidifiers using the principle of ultrasound are widely used for home use, and in the hospital, various kinds of information needed by the doctor are obtained by using different degrees of reflection of ultrasound waves from living tissues. Applied to monitor the beating, it is widely used in diagnostics such as cancer screening. It is also used to treat patients, which can be cured by smashing and destroying stones by squeezing ultrasound into gallstones or kidney stones. In addition, beer factories use beer to foam bubbles into the bottles to prevent air from entering the bottles. In addition, recently, a tool is attached to an ultrasonic generator to be used for welding, drilling, etc., and it is also used for underwater communication by using the strong straightness of ultrasonic waves. In addition, ultrasonic waves are conveniently used in many other places.

In the ultrasonic application field described above, an ultrasonic cleaner, in particular, used for washing dishes or fruits, is a mainstream method of washing fruits by ultrasonic waves by putting dishware or fruits to be washed in a washing container.

However, objects such as tableware can be immersed in the washing water in the ultrasonic cleaning container so that all parts can be washed well.However, objects to be cleaned such as fruits and vegetables are bulky but have a portion floating in the cleaning container due to buoyancy. do. In this case, washing is performed only up to the part where the washing water touches and there is a problem that the part floating on the water is not completely washed.

In order to compensate for this disadvantage, an ultrasonic cleaner having a device for generating bubbles in the ultrasonic cleaning container to turn over the object to be cleaned, such as fruits, has been proposed. However, when the objects to be washed are inverted and flowed by bubbles, the objects to be cleaned are damaged by colliding with each other or by colliding with the wall or the bottom of the cleaning container. In particular, if the object to be cleaned is a fruit or vegetable, such damage greatly reduces the fruit or vegetable's marketability.

Therefore, an object of the present invention is to provide an ultrasonic cleaner which can be cleaned without damaging the object to be cleaned, such as fruits and vegetables contained in the cleaning container of the ultrasonic cleaner.
