【考案の詳細な説明】
（産業上の利用分野）
本考案は洗浄用超音波振動子、特に洗浄領域の
拡大に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an ultrasonic vibrator for cleaning, and particularly to an expansion of the cleaning area.
（従来技術とその問題点）
超音波洗浄機においては第１図ａの断面図の如
く、金属輻射板２を備えた超音波振動子１所謂振
動板型振動子を、洗浄槽３の底部に設けた切欠部
３ａを閉塞するようにパツキン４を介して水密に
取付けることが行われる。この場合金属輻射板２
の固定板部２ａの長さを、例えば第１図ｂの振幅
分布図のように、λ／４（λは波長）に相当する
長さとすることにより、固定が振動零の点、即ち
振動の節において行われるようにして、振動によ

いる。(Prior art and its problems) In an ultrasonic cleaning machine, as shown in the cross-sectional view of FIG. Watertight mounting is performed via the gasket 4 so as to close the provided notch 3a. In this case, metal radiation plate 2
By setting the length of the fixing plate part 2a to a length corresponding to λ/4 (λ is the wavelength), for example, as shown in the amplitude distribution diagram of FIG. This is done at the joints so that the fixing is not affected by vibrations.
しかしこれでは振動子１の一端部から固定部２
ｂに至るに伴い振動振幅が減退することになる。
このため例えば第１図に示すように被洗浄物５が
振動振幅の減衰領域に跨るような大きさのもので
あつた場合には、その両端部において洗浄効果の
低下を招く。従つてこれを回避するためには被洗
浄物５の大きさを第１図中に点線により図示する
ように限定するか、第１図中の点線図示のように
被洗浄物５より大きい振動輻射面をもつ振動子１
を用いる必要がある。しかし実際上被洗浄物の大
きさの制限は難しい。また振動子を大とする方法
では振動子の製作コストが高くなるばかりでな
く、振動子の励振電力も大となることからランニ
ングコストが高くなる。 However, in this case, from one end of the vibrator 1 to the fixed part 2
The vibration amplitude decreases as it reaches b.
For this reason, if the object to be cleaned 5 has a size that straddles the vibration amplitude attenuation region as shown in FIG. 1, for example, the cleaning effect will be reduced at both ends thereof. Therefore, in order to avoid this, the size of the object to be cleaned 5 should be limited as shown by the dotted line in FIG. 1, or the vibration radiation larger than the object to be cleaned 5 should be Oscillator 1 with a surface
It is necessary to use However, in practice, it is difficult to limit the size of the object to be cleaned. Furthermore, the method of increasing the size of the vibrator not only increases the manufacturing cost of the vibrator, but also increases the running cost because the excitation power for the vibrator also increases.
（考案の目的）
本考案は上記の如き欠点を簡単に除去できる超
音波振動子の提供を目的としてなされたものであ
る。(Purpose of the invention) The present invention has been made for the purpose of providing an ultrasonic transducer that can easily eliminate the above-mentioned drawbacks.
（問題点を解決するための本考案の手段）
本考案の特徴とするところは、第２図ａ，ｂに

音波振動子１を備えた金属輻射板２の固定部２ｂ
から先の長さを、或る長さ例えばλ／４（λは波
長）に相当する長さだけ長くした延長振動板部６
を設けて、この部分に超音波振動子１の振動と逆
位相の横波振動を生じさせるようにした点にあ
る。(Means of the present invention for solving problems) The present invention is characterized by having an ultrasonic transducer 1 as shown in the sectional view and amplitude distribution diagram of an embodiment shown in FIGS. 2a and 2b. Fixed part 2b of metal radiant plate 2
An extended diaphragm portion 6 whose length is increased by a certain length, for example, λ/4 (λ is the wavelength).
The point is that a transverse wave vibration having a phase opposite to that of the vibration of the ultrasonic transducer 1 is generated in this portion.
（考案の効果）
以上のようにすれば超音波振動子を大型として
洗浄領域の拡大を図る従来方法のように、超音波
振動子や洗浄槽の大型化による製作コストの上昇
を招いたり、ランニングコストを高くすることな
く、延長部分を設けるのみの簡単かつ低コストの
手段によつて洗浄領域を拡大することができる。
また第２図のように延長部分６の先端が洗浄槽３
の側面近くに位置するように洗浄槽３の大きさを
設計することになり、洗浄槽３の全域に亘つてほ
ぼ均一な洗浄力が得られるため、従来の洗浄機の
ように被洗浄物の大きさによつて洗浄効果が異な
るおそれもない。(Effects of the invention) If the above method is used, unlike the conventional method of increasing the size of the ultrasonic vibrator to expand the cleaning area, it would not be possible to increase the manufacturing cost due to the enlargement of the ultrasonic vibrator or cleaning tank. The cleaning area can be expanded without increasing costs by a simple and low-cost means of simply providing an extension.
Also, as shown in Figure 2, the tip of the extension part 6 is connected to the cleaning tank 3.
The size of the cleaning tank 3 is designed so that it is located near the side of the tank, and almost uniform cleaning power can be obtained over the entire area of the cleaning tank 3, so it is possible to clean the objects to be cleaned like a conventional cleaning machine. There is no possibility that the cleaning effect will differ depending on the size.
（他の実施例）
以上本考案を一実施例について説明したが、例

適当量だけ上方に湾曲させ、これにより図中に点
線によつて図示するように洗浄領域を拡大しなが
ら浸漬された被洗浄物５に振動を集中させて洗浄
力を強勢することもできる。(Other Embodiments) The present invention has been described above with respect to one embodiment. For example, as shown in the cross-sectional view of FIG. 3, the extended diaphragm 6 may be bent upward by an appropriate amount. As shown in the figure, it is also possible to increase the cleaning power by concentrating vibrations on the immersed object 5 while enlarging the cleaning area.

The cleaning area can also be expanded by providing an extended diaphragm section 6 for a device in which a fixed device is used at the bottom of the cleaning tank. Note 8
is a flexible hose for cord extraction.
