器1の内部を気密状態に保持するようになっている。A container 1 of this ultrasonic cleaner is formed into a substantially box shape with an open top, and a flange 2 is provided protruding from the outer periphery of the top end. A plurality of objects 3 to be cleaned are housed in this container 1, and a cleaning liquid 4 is also housed therein, so that the objects 3 to be cleaned are immersed in the liquid 4. The lid 5 is mounted on the flange 2 of the container 1 via a gasket 6 so as to cover the upper opening of the container 1 in an openable and closable manner. A plurality of fasteners 7, which constitute a sealing means together with the lid 5 and the gasket 6, are attached across the outer peripheral edge of the lid 5 and the flange 2 of the container 1, and are attached to bolts 8.
By tightening, the lid body 5 is brought into close contact with the upper surface of the container 1, and the inside of the container 1 is maintained in an airtight state.

が液体4に付与されるようになっている。The ultrasonic vibrator 9 constituting the ultrasonic generating means is connected to the liquid 4.
attached to the lower surface of the lid 5 so as to be immersed in the
It is connected to an ultrasonic oscillator 10 provided outside the container 1. Then, as the ultrasonic oscillator 10 operates, ultrasonic waves are generated from the ultrasonic transducer 9, and the ultrasonic energy is applied to the liquid 4.

所定の圧力に加圧保持される。An air intake port 11 is formed in the lid 5 and is connected to an air compressor 13 as pressurizing means via an air pressure regulating valve 12. Then, a predetermined amount of air is supplied from the air compressor 13 into the container 1 according to the pressure adjustment of the air pressure regulating valve 12, and the inside of the container 1 is kept under pressure at a predetermined pressure of, for example, about 5 kgf/cm'. Ru.
次に、前記のように構成された超音波洗浄機について作

1の内部圧力を所定値まで高める。First, the object 3 that needs to be cleaned is washed with the liquid 4 in the container 1.
It is housed so that it can be directly immersed in water. Thereafter, the lid 5 is placed on the top of the container 1 through the gasket 6 to make the inside of the container airtight. Air is then supplied into the container 1 to increase the internal pressure of the container 1 to a predetermined value.
この状態で超音波発振器10を作動させると、超音波振
動子9から超音波が発生されて液体4全体が超音波振動

生じた気泡の振動によって、液体中に置かれた物体の近
傍に小さな流れが生ずる。When the ultrasonic oscillator 10 is operated in this state, ultrasonic waves are generated from the ultrasonic vibrator 9 and the entire liquid 4 is ultrasonically vibrated. Then, due to the effects of the generation and bursting of cavitation based on this ultrasonic vibration and the vibration of the bubbles generated by the cavitation, a small flow is generated near the object placed in the liquid.
従って、複雑な形状の被洗浄物であっても液体中にあれ

ができる。Therefore, even if the object to be cleaned has a complicated shape, it can be reliably cleaned if it is immersed in the liquid. At this time, since the inside of the container 1 is in a pressurized state, pressure is applied to the liquid containing air, which removes air bubbles and increases the cavitation threshold. Therefore, the energy of cavitation generation and rupture is greater than that under normal pressure, and the straight flow and flow in the liquid become more intense.
An object to be cleaned can be easily and reliably cleaned in a short time.

よい。It should be noted that the present invention is not limited to the configuration of the embodiment described above, but may be configured such that ultrasonic vibrations are applied to the liquid 4 through the container 1. Further, a heating means such as a heater and a temperature sensor may be provided in the container 1 to control the liquid 4 to be maintained at a constant temperature to obtain an optimum cleaning state.
