Ultrasonic cleaning apparatus and ultrasonic claning method

Abstract

Provided is an ultrasonic cleaning apparatus capable of efficiently utilizing ultrasound, cleaning with a small amount of a cleaning liquid, and contributing to downsizing of the apparatus. The ultrasonic cleaning apparatus 10 can provide an ultrasonic wave with almost no attenuation to the cleaning liquid 27 and can strongly provide an ultrasonic vibration to the cleaning liquid 27 by an ultrasonic vibration unit 15 which is directly mounted on a cleaning drum 14 and is rotated together therewith. For the ultrasonic vibration unit 15, it is unnecessary to use a large output in consideration of attenuation, and the cleaning liquid 27 can be vibrated efficiently and with a small amount of electric power consumption by ultrasonic vibration. In addition, as the ultrasonic vibration unit 15 is directly mounted on the cleaning drum 14, it is unnecessary to use a liquid and an outer tank for transmitting the ultrasonic vibration to the surrounding of the cleaning drum 14, and it is therefore possible to remarkably perform size reduction and weight reduction of the ultrasonic cleaning apparatus 10.

Description

technical field [0001] The invention relates to an ultrasonic cleaning device, in particular to an ultrasonic cleaning device using a rotary cleaning cylinder. Background technique [0002] Ultrasonic cleaning devices that use an ultrasonic vibrator or the like to generate ultrasonic vibrations in a cleaning liquid such as water to remove dirt adhering to the object to be cleaned are widely used. Such an ultrasonic cleaning device generally installs an ultrasonic vibrator on the bottom surface of a cleaning tank storing a cleaning liquid to ultrasonically vibrate the cleaning liquid. [0003] On the other hand, in order to improve the cleaning ability of such an ultrasonic cleaning device and realize high-efficiency cleaning, an ultrasonic cleaning device equipped with an ultrasonic generating mechanism such as an ultrasonic vibrator on a cleaning device called a spiral cleaner is widely known. (For example, refer to Patent Document 1) [0004] 【Patent Document 1】 [0005...

AI Technical Summary

Problems solved by technology

Therefore, the ultrasonic wave generated by the outer tank has been attenuated when it is transmitted into the cleaning cylinder, and it is difficult to use the generated ultrasonic wave to clean effectively, and the loss of the ultrasonic wave is also large.

In addition, in order to transmit the ultrasonic wave to the cleaning liquid in the cleaning cylinder, in addition to the cleaning liquid in the cleaning cylinder used for cleaning, the outer tank containing the cleaning cylinder must also be filled with cleaning liquid, and the loss of cleaning liquid is large, resulting in Obstacles to miniaturization of cleaning devices
