Description

Ultrasonic cleaner {Supersonic waves cleaner}

The present invention relates to an ultrasonic cleaner, and more particularly, to an ultrasonic cleaner capable of further improving the cleaning efficiency through a large area of a vibration plate that causes vibration in connection with a vibration element.

In general, the ultrasonic cleaner is a device that causes vibration in the ultrasonic frequency band of about 20,000 Hz or higher when electricity is applied. It washes microscopic impurities attached to semiconductor parts or other precision parts, or cleans dishes, parts, skin massagers, etc. It is used in the field of products for cleaning toothbrushes with vibration.

The ultrasonic vibrator of such an ultrasonic cleaner converts an electrical signal into mechanical ultrasonic vibration when electric power is applied, and transmits it to the inside, including a piezo electric element therein, and a piezoelectric element at this time It is made of a structure that uses the vibration generated in the washing.

Normally, an ultrasonic cleaner is installed on the bottom surface of a washing tank having a predetermined size to allow the washing liquid to be contained, and when the vibration generated by the vibrator is transmitted to the washing liquid contained in the washing tank by electrical operation, it is propagated to the washing liquid. It is made in such a way that various foreign matters deposited on the washing matter settled in the washing liquid are removed due to the vibration module.

The ultrasonic cleaner is basically a washing tank having a predetermined size to allow the upper surface to be opened and the washing liquid to be contained through the opening at this time, and installed on the bottom surface of the washing tank to generate vibration by electrical operation. It consists of a structure comprising a plurality of vibrators.

As an example, Korean Registered Utility Model 20-0409300 discloses a structure of an oscillator for an ultrasonic cleaner.

The "oscillator structure for the ultrasonic cleaner" receives electric signals from the front vibrating element 2 for transmitting vibration to the washing tank 12, an ultrasonic oscillator (not shown), and terminals 3 and 3a electrically grounded. It is composed of a piezoelectric ceramic element (4,4a) for generating a mechanical signal, a rear vibration element (5) for transmitting ultrasonic vibration in one direction, and a support rod (6) for coupling the respective components.

Therefore, when an electrical signal is transmitted from the ultrasonic oscillator, the front and rear vibration elements 2 and 5 vibrate, and the ultrasonic wave is generated while the bottom plate 13 of the washing tank is shaken. Foreign matter and the like can be removed.

However, in the above-mentioned "structure of the vibrator for the ultrasonic washer", since the vibrator is attached to the bottom of the washing tank, there is a limit in which vibration is transmitted in only one direction, and eventually there is a limit to increase the washing ability, and the entire washing tank bottom causes vibration. There is a disadvantage that noise (howling phenomenon) is severely generated.

As another example, Korean Patent Registration No. 10-1648710 discloses an “oscillator coupling assembly of an ultrasonic cleaner”.

The `` vibrator coupling assembly of the ultrasonic cleaner '' includes a water tank including at least one coupling hole formed through one side of the surface, and vibrations including wings formed to protrude along the circumference on one side in the longitudinal direction by transmitting vibration to the water tank. Sieve, stacked on the lower surface of the vibrating body, includes a piezoelectric element that receives electrical signals through a terminal, converts it into vibration, and transmits it to the vibrating body, and a stacked body on the lower surface of the piezoelectric element that extends in the longitudinal direction. It includes a vibrator to be formed, and a wing receiving groove formed along the periphery on one side of the inner circumferential surface of the hollow to include the hollow formed through the longitudinal direction, and the coupling hole in a state where the vibrator is accommodated in the hollow. And is projected from the top to the outside along the circumferential direction. It includes a main body having a long formed stepped side, a hollow portion penetrating in the longitudinal direction, and includes a subbody fitted in the outer circumferential surface of the main body and a hollow portion penetrating in the longitudinal direction, and is fitted in the inner circumferential surface of the main body. It consists of a housing that includes an auxiliary body.

However, the `` vibrator coupling assembly of the ultrasonic washer '' has the advantage of providing a variety of vibration transmission paths than when attached to the bottom of the tank because the upper surface of the vibrator is exposed, but the vibration of each vibrator has a small area. As it is a structure that generates vibration depending on the sieve, the vibration performance is poor, so there is a burden in economical aspects such as having a large number of vibrators, as well as manufacturing and assembling, and disadvantageous in terms of A / S or maintenance. There is a point.

In addition, since both of the above-mentioned `` oscillator structure for the ultrasonic washer '' and `` the oscillator coupling assembly of the ultrasonic washer '' need to replace the entire washing tank including the oscillator, there is a problem that A / S cost is high, and most of the A in the field Since the / S work is difficult, there is a problem that a lot of time is wasted due to repairs and replacements, such as having to deal with it after receiving it in a factory.
