Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an ultrasonic cleaner, and more particularly to an ultrasonic cleaner in which the direction of irradiation of ultrasonic waves can be controlled.

(Prior Art) Ultrasonic cleaning machines are often used for cleaning mechanical parts, electronic parts, and the like. Among these ultrasonic cleaning machines, there is a nozzle-type ultrasonic cleaning machine that applies ultrasonic vibrations to a medium that is sprayed toward the object to be cleaned, and thereby performs ultrasonic cleaning of the object to be cleaned. There is.

(Issues to be solved) However, this conventional nozzle-type ultrasonic cleaning machine does not have a means to control the irradiation direction and irradiation intensity of ultrasonic waves, and it can be used to clean various objects with different materials, shapes, etc. However, it is difficult to carry out efficient ultrasonic cleaning work, and the adjustment work is extremely difficult. The purpose of this invention is to solve this problem with ultrasonic cleaning machines, and it is a novel technology that allows more efficient ultrasonic cleaning by freely controlling the direction and intensity of ultrasonic irradiation. The purpose is to provide an ultrasonic cleaning machine.

(Means) In this invention, a nozzle portion having a reduced diameter in a funnel shape is attached to one open end of a cylindrical or box-shaped main body, a medium supply pipe is attached near the periphery of the closed surface of the other end, and the outer periphery is In a nozzle-type ultrasonic cleaning machine in which an ultrasonic vibrator is attached to a wall, a reflector is attached to the inside of the closed surface to bend the ultrasonic waves emitted from the ultrasonic vibrator toward the nozzle part. This configuration aims to solve the above problems.

(Function) A medium such as city water, pure water, or solvent is fed into the main body from the medium supply pipe, and ultrasonic vibrations are applied to the medium from the ultrasonic vibrator attached to the outer peripheral wall of the main body. Ultrasonic cleaning is performed by spraying onto the object to be cleaned. At this time, the propagation direction of the ultrasonic waves emitted from the ultrasonic vibrator toward the inside of the main body is refracted toward the nozzle by the reflector, and the energy is concentrated in the medium ejected from the nozzle. Therefore, ultrasonic power can be used effectively and power loss can be prevented. Furthermore, by changing the direction of the reflector and the shape of the reflector, the irradiation direction and intensity of the ultrasonic waves can be freely changed, making it possible to perform cleaning tasks according to the material and contamination status of the object to be cleaned. .

(Embodiment) FIG. 1 is a sectional view of an embodiment of an ultrasonic cleaning machine according to the present invention.

In the figure, reference numeral 1 denotes a cylindrical main body, and a nozzle portion 2 having a reduced diameter funnel shape is attached to one open end of the main body 1. The other end of the main body 1 is closed to form a closed surface 3, and an overflow bubble removal pipe 4 is attached to the upper part of this closed surface 3, and a medium supply pipe 5 is attached to the lower part.

An ultrasonic transducer 6 is attached to the outer circumferential wall of the main body l, so that ultrasonic waves can be irradiated into the main body l.

On the other hand, a reflector 7 is attached to the center of the closed surface 3 with its apex directed toward the nozzle portion 2, which bends the ultrasonic waves irradiated into the main body 1 from the ultrasonic transducer 6 toward the nozzle portion 2. There is. This reflector 7 is a member that has the function of reflecting ultrasonic waves on its surface, and in this embodiment, the reflector 7 has a simple conical shape.
#=6 As shown in the figure, a pyramid-shaped or dome-shaped reflector 7
' may be used, and the most suitable one may be selected based on conditions such as the degree of concentration of ultrasonic waves and the direction. In FIG. 1, the arrow (a) indicates the propagation direction of the ultrasonic wave, and the arrow (a) indicates the flow direction of the medium.

(Effects of the Invention) The ultrasonic cleaning machine according to the present invention has the above configuration, and the ultrasonic waves emitted from the ultrasonic vibrator are bent in the direction of irradiation by the reflector and concentrated toward the nozzle. Therefore, ultrasonic cleaning work can be performed efficiently even if an ultrasonic vibrator with a smaller output than the conventional one is used. In addition, by changing the shape and orientation of the reflector, the intensity and irradiation method of the ultrasonic waves applied to the object to be cleaned can be freely changed, allowing for more fine-grained control and extremely high practicality. It is something that you have.
