にある。以下図面の実施例について説明する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvement of a cleaning tank used in an ultrasonic cleaning machine, and its purpose is to diffusely reflect ultrasonic waves emitted from an ultrasonic vibration radiator within a cleaning liquid to create a standing wave. It is an object of the present invention to provide an ultrasonic cleaning tank that suppresses the generation of ultrasonic waves and the absorption of ultrasonic waves, and enhances the cleaning effect. The embodiments shown in the drawings will be described below.

を具えた投込み型構造のものを用いた。 In the drawing, 1 is a cylindrical cleaning tank, and 2 is the tank 1.
3 is an ultrasonic vibration radiator which is immersed in the liquid and placed on the bottom of the tank. The upper end surface 31a of the metal outer casing 31 is used as a vibration radiation surface, and inside thereof, a large number of ultrasonic transducers 32 such as Languevent type transducers are arranged in a mosaic pattern, and these transducer groups are electrically wired in parallel. , one end of which is connected to the wiring bundle, the other end of which is led out from the outer casing 31 in a liquid-tight manner and extended to an external high-frequency oscillator (not shown).
We used a type with an immersion type structure.
而してここまでの構成は従来と変わりないが本
発明においては洗浄槽１の外形状を、槽内に収納

数の連続した曲面１b1〜１b10に歪曲されてなる
円筒状に形成したものである。 The configuration up to this point is the same as the conventional one, but in the present invention, the outer shape of the cleaning tank 1 is such that the bottom surface 1a facing the liquid surface 2a of the cleaning liquid 2 stored in the tank is non-parallel to the liquid surface 2a. It is formed into a cylindrical shape with the side surface constituting the outer circumference of the tank being distorted into a large number of continuous curved surfaces 1b 1 to 1b 10 with different radii of curvature r 1 to r 10 .
なお、上記実施例において超音波振動放射体３
を洗浄液２中に浸漬して槽の底面１ａ上に設置し

着することができる。 In addition, in the above embodiment, the ultrasonic vibration radiator 3
Although the embodiment is shown in which the ultrasonic vibration radiator is immersed in the cleaning liquid 2 and installed on the bottom surface 1a of the tank, it may also be installed outside the tank bottom surface 1a.
A plurality of ultrasonic transducers indicated by 32 in the figure can be directly bonded.
従来、この種超音波洗浄槽は底面が液面に対し
て平行で、外周側面が正円形な円筒状から構成さ
れているため、槽底面に取付けた超音波振動放射
体から放射される超音波が前記底面と平行する液
面によつて放射方向とは逆向きに反射されるが、
この反射液が放射波と重なつて、いわゆる定在波
が洗浄液中で発生し、更にまた外周側面が正円形
のため該側面に当たつて反射する超音波は中央に
収れんして外周部分との間に超音波密度の濃淡を
生じ、いずれも洗浄効率を低くしていた。 Conventionally, this type of ultrasonic cleaning tank has a cylindrical shape with a bottom parallel to the liquid level and a circular outer circumferential side. is reflected in the opposite direction to the radiation direction by the liquid surface parallel to the bottom surface,
When this reflected liquid overlaps with the radiated wave, a so-called standing wave is generated in the cleaning liquid.Furthermore, since the outer peripheral side surface is a perfect circle, the ultrasonic waves that hit the side surface and are reflected converge to the outer peripheral part. During this period, the ultrasonic density varied, resulting in low cleaning efficiency.
然るに本案の洗浄槽は上述したように、底面が
液面に対して傾斜しており、外周側面が曲率半径
の異なる多数の連続した曲面に歪曲された円筒状
より構成したから、槽の底面に取付けた超音波振
動放射体からの超音波は前記底面と非平行をなす
液面や曲率の異なる側面によつて乱反射されて洗
浄液内を進行するため定在波および超音波の収れ
んを惹起するようなことはなく、従つて液中の音
圧分布を均一にし洗浄効果を著しく高めることが
できるのである。 However, as mentioned above, the cleaning tank of the present invention has a cylindrical shape in which the bottom surface is inclined with respect to the liquid level and the outer peripheral side surface is curved into a number of continuous curved surfaces with different radii of curvature. The ultrasonic waves from the attached ultrasonic vibration radiator are diffusely reflected by the liquid surface that is non-parallel to the bottom surface and by the side surfaces with different curvatures and propagate through the cleaning liquid, causing standing waves and convergence of the ultrasonic waves. Therefore, the sound pressure distribution in the liquid can be made uniform and the cleaning effect can be significantly enhanced.
