It can be introduced while laying down.

The lower portion of the inner cylinder 32 is provided with an ultrasonic generator 10, by the ultrasonic generation can remove the harmful substances on the surface of the vegetable or fruit contained in the water of the inner cylinder (32).

Ultrasonic cleaning uses the special energy of ultrasonic waves as a power source, and this energy is very large. When ultrasonic waves are irradiated in a liquid, an innumerable cavitation (hereinafter, referred to as 'vacuum bubbles') occurs.

The above-mentioned vacuum bubble is repeated 25,000 ~ 30,000 times generation and disappearance per second. Ultrasonic cleaning uses the sound of the ultrasonic wave and this cavitation effect.

The vacuum bubble is accompanied by a chemical and thermal action due to the very small stirring and breakage of the bubble due to vibration.

The complex repetition of these actions increases the acceleration and dispersal of chemical reactions in the wash solution, so that foreign substances adhering around the object to be cleaned can be cleaned even in small holes or invisible dirt.

The ultrasonic generator generally used vibrates from 20,000 to 1 million times per second according to the frequency and is expressed in frequency according to the frequency.

For example, an ultrasonic vibrator that vibrates 20,000 times per second has a frequency of 20 KHz.

When the ultrasonic vibrator gives a certain electrical signal, the ultrasonic vibrator repeats contraction and expansion by frequency and vibrates the diaphragm attached to the ultrasonic vibrator.

When the diaphragm vibrates, a vacuum bubble is generated in the water, and the vacuum bubbles explode and contract while expanding and contracting and expanding while the vibration bubble continues and does not maintain its shape.

When the vacuum bubbles explode, micro-local heat of 5000 ° C. or more is generated, and a very high-speed plasma of 800 km / h generated by the explosion hits the surface of the object in the cleaning tank to remove contamination.

Millions of these vacuum bubbles are generated in a second, and the cleaning is performed.

On the other hand, the level sensor 4 is a device for adjusting the amount of water to be stored in the inner cylinder, in the embodiment of the present invention a magnet sensor (magnet sensor) is used.

In addition, a predetermined cover is installed on the upper portion of the washing tank (3).

In this way, the ultrasonic cleaner (A) of the present invention, in which the coupling is completed, puts vegetables and fruits into the inner cylinder 32 of the washing tank 3, closes the cover, and then operates the control unit to turn on the ultrasonic cleaner (A). Water supply starts when the water supply valve 62 is opened, and when a proper amount of water is input, the water level sensor 4 detects the water level and sends a signal to the control unit. The valve 62 is closed to stop the water supply.

In another embodiment, by installing the ON / OFF sensor on the cover to close the cover to operate the ultrasonic cleaner (A) of the present invention, it may be stopped by opening the cover.

Thereafter, the ultrasonic generator 10 is operated to start the washing operation of removing harmful substances on the surface of the vegetables and fruits by the explosion and water flow of the vacuum bubbles generated by the ultrasonic waves.

At this time, the water of the inner cylinder 32 is continuously circulated by the operation of the circulation device 2 to prevent the closed end that is eliminated by the interference between the vacuum bubbles.

After the above-described ultrasonic cleaning and operation of the circulator are performed for a predetermined time, the operation of the ultrasonic generator 10 and the circulator 2 is automatically stopped by the control of the controller.

Thereafter, the drain pipe 8 is opened to discharge the washed sewage.
