ことは以下の点が考慮される。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the cleaning apparatus according to the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a cleaning tank that can store the cleaning liquid W. The cleaning liquid W that has reached the upper opening 1A of the cleaning tank 1 is returned to the liquid storage tank 7 through the overflow passage 2, and thereby the cleaning tank 1 There is a certain cleaning liquid W inside
Is stored. Reference numeral 3 denotes a work attached to the work support 4, and the work 3 is the cleaning tank 1 by the work support 4.
It is disposed so as to be able to advance and retreat in the cleaning liquid W therein, and is provided with rotation. Note that, instead of rotating the work 3, an injection nozzle described later may be rotated. 5 is one side wall 1B of the cleaning tank 1.
(A left side wall in FIG. 1) and an injection nozzle arranged opposite to the work 3 in the cleaning liquid W, and more specifically, the opening 5B of the injection hole 5A is formed on one side wall 1B.
It faces further toward the work 3. Then, the cleaning liquid W in the storage tank 7 is pressurized by the cleaning liquid pump P, and the pressurized cleaning liquid W is supplied to the work through the cleaning liquid W in the cleaning tank 1 through the opening 5B of the injection hole 5A of the injection nozzle 5. Injected toward 3. Then, the inventor of the present invention determines the inner wall 1C of the cleaning tank 1 facing the opening 5B of the injection hole 5A of the injection nozzle 5.
(In other words, the right side wall in FIG. 1 facing one side wall 1B of the cleaning tank 1 in which the injection nozzle 5 is arranged) There is a difference in the cleaning effect of the work 3 depending on the distance L from the center XX of the work 3. We paid attention to that. FIG. 2 is a test result showing the relationship between the distance L between the inner wall 1C of the cleaning tank 1 and the center XX of the work 3 and the foreign matter removal efficiency. The removal ratio is expressed by the ratio of the foreign matter removal length A / the diameter d) of the injection hole 5A, and the larger the absolute value, the higher the removal efficiency. On the other hand, the horizontal axis represents the distance L between the inner wall 1C of the cleaning tank 1 and the center XX of the workpiece 3 in the ratio of (distance L between the inner wall 1C of the cleaning tank 1 and the center of the workpiece 3 / diameter d of the injection hole 5A). The distance L between the inner wall 1C of the cleaning tank 1 and the center XX of the work 3 increases as the absolute value increases. Then, the test was performed on the workpiece 3 having a diameter of 20 mm and a jet pressure of the cleaning liquid W of 20 kg / C.
At m2, the diameter φd of the injection hole 5A of the injection nozzle 5 was changed to 1.5 mm and 2.5 mm. The test result is shown in FIG. 2. When the diameter of the injection hole 5A of the injection nozzle 5 is 1.5 mm, the removal efficiency drops sharply from 22.5 when L / d is 27 or less, and the injection nozzle 5 When the diameter of the hole 5A is 2.5 mm, the removal efficiency sharply drops from 14 when L / d is 27 or less. As described above, when L / d is 27 or less, the abrupt decrease in removal efficiency is considered as follows.

ことがないものである。That is, the cleaning liquid W in the liquid storage tank 7 is pressurized by the cleaning liquid pump P,
A is sprayed toward the work 3 from the opening 5B of A through the cleaning liquid W in the cleaning tank 1. When the pressurized cleaning liquid W is injected into the cleaning liquid W in the cleaning tank 1 from the opening 5B of the injection hole 5A, cavitation bubbles are generated. The cavitation bubbles are destroyed to generate a large impact pressure, and foreign matter on the work 3 is removed by the impact pressure and the physical direct force of the jetted cleaning liquid W. On the other hand, although the impact pressure and the direct impact force that collide with the work 3 impinge on the work and perform a cleaning action, their energy is reduced, but they still have high impact and direct energy, and these are the work energy. 3 and proceeds toward the inner wall 1C of the cleaning tank 1 facing the opening 5B of the injection hole 5A of the injection nozzle 5. And these impact pressure and direct impact force are
After the collision with the nozzle 5, it returns toward the opening 5 </ b> B of the injection nozzle 5 and advances again. According to this, it has an effect of opposing impact pressure and direct injection force from the injection hole 5A of the injection nozzle 5 toward the work 3, and the injection hole 5A of the injection nozzle 5
Thus, the impact pressure toward the work 3 and the direct blast force are weakened. As described above, when the distance L between the center XX of the work 3 and the inner wall 1C of the cleaning tank 1 facing the opening 5B of the injection hole 5A of the injection nozzle 5 is less than 27d, the nozzle collides with the inner wall 1C and the injection nozzle The return of the impact pressure and the direct injection force to the injection hole 5A of the nozzle 5 is fast and the force is large, which impairs the cleaning effect. On the other hand, when the distance L is 27d
In the above, the impact pressure against the injection hole 5A of the injection nozzle 5 due to the collision with the inner wall 1C, the return of the direct injection force after reflection is slow, and the force itself decreases due to the increase in the distance L. Thus, the resistance to the impact pressure and the direct blast force injected toward the work 3 from the injection hole 5A can be reduced, so that the cleaning effect on the work 3 is not hindered.

By setting it to 27d or more, a large cleaning effect of the work can be obtained, and its practical effect is extremely large.
