However, since ultrasonic waves affect the way of contacting the article to be washed, it is difficult to wash the dirt attached to the article to be washed evenly and in a short time. In the case of cleaning, shielding between articles occurs because each part is small. For this reason, the ultrasonic waves are absorbed on the surface of the layer on which the articles to be cleaned are stacked, and the ultrasonic waves are weakened at the central portion, so that the cleaning unevenness is remarkable and there is a limit to the amount that can be processed by one cleaning.

本の場合（図示せず）とがある。The vertical container 7 is preferably as long as possible in order to accommodate a large number of objects to be cleaned a with a relatively small cross-sectional area. Therefore, the ratio between the diameter and the height is set in the range of about 1 to 10, preferably about 2 to 5 with respect to the former. The diameter of the vertical container 7 is not particularly limited, and may be appropriately determined depending on the type of the article to be cleaned, but is usually about 1 cm to 1 m. Preferably 5c
m to 50 cm, more preferably 8 cm to 30 cm. The number of vertical containers 7 inserted and installed in the washing tower 4 is arbitrary, and may be one as shown in FIG. 1 or a plurality (not shown).

る。The cleaning method of the present invention is basically for cleaning an object to be cleaned a using such a cleaning apparatus. Hereinafter, such a basic cleaning method will be described.
That is, in the state shown in FIG. 1, the cleaning agent 2 in the liquid tank 1 is forcibly circulated in the liquid circulation line 3 by operating the liquid supply pump 5, so that the cleaning agent 2 The object to be cleaned a is cleaned while entering the vertical container 7 through the chamber 4a and forcedly flowing through the vertical container 7 in the axial direction. The cleaning agent 2 that has cleaned the object to be cleaned a enters the lower part of the lower chamber 4b of the washing tower 4 from the lower end of the vertical container 7, and further rises in the lower chamber 4b, passes through the return path 3b and enters the liquid tank 1 through the return path 3b. Return to and be used cyclically. During this cleaning operation, the valves V1 and V2 are kept open and V3 to V5 are kept closed.

の被洗浄物ａの洗浄処理をすることができる。In the cleaning method using such a cleaning device, the vertical container 7 is vertically elongated and has a relatively small cross-sectional area. In addition, since there is no liquid passage hole in the body 7b, liquid cannot be passed, and only the bottom 7a is provided. Since the cleaning agent 2 has a liquid passage hole and passes from the upper end to the lower end, the cleaning agent 2 comes into contact with the cleaning target a at a relatively high flow rate and effectively, and efficiently cleans the oils and fats and the fine powder. be able to. Further, even when the stacking height of the articles to be cleaned a is relatively large, the entire flow of the cleaning agent 2 passes through the vertical cylinder 7, so that the flow rate of the cleaning agent 2 in the vertical cylinder 7 is It is almost constant from the upper end to the lower end, and the object to be cleaned a
Can be uniformly cleaned, so that a large number of objects to be cleaned a can be cleaned at one time.

ましい。Since the flow rate of the cleaning agent 2 forcibly flowing through the vertical container 7 is substantially constant from the upper end to the lower end, the cleaning efficiency can be increased by increasing the flow rate. What is necessary is just to adjust suitably according to a kind, storage amount, the kind of the adhered dirt, etc. Usually, the flow rate of the cleaning agent is preferably about 3 to 200 cm / s, and the cleaning time is about 30 seconds to 120 minutes. Further, the washing temperature is about 10 to 90 ° C. To shorten the drying time, it is desirable that the temperature be as high as possible within the usable temperature range.

と接触する本発明に比し接触効率が低下してしまう。When the bottom 7a and the body 7b of the vertical cylinder 7 are provided with liquid passage holes, a part of the cleaning agent 2 passes through the body while passing through the inside of the vertical cylinder 7. Since the cleaning agent 2 flows out of the vertical cylinder 7 through the liquid hole, the flow rate of the cleaning agent 2 in the vertical cylinder 7 gradually decreases as it goes downward, and the average flow rate in the vertical cylinder 7 decreases. The flow rate will be considerably lower than in the present invention, depending on the opening / closing rate of the body. Further, the cleaning agent 2 which has flowed out through the liquid passage hole in the body of the vertical cylinder is again subjected to the cleaning object a.
Since there is no contact with the object to be cleaned a, the amount of the cleaning agent 2 in contact with the object to be cleaned a is also reduced, and the entire amount of the cleaning agent 2 is
The contact efficiency is reduced as compared with the present invention in which the contact is made.

液の返送ライン６を兼用することができる。The return path 3b of the liquid circulation line 3 may be provided between the bottom of the lower chamber 4b of the washing tower 4 and the liquid return port 1b of the liquid tank 1. In this case, the return path 3b can also serve as the return line 6 for the residual cleaning solution.

At the bottom of the lower chamber 4b of the washing tower 4 and at the return path 3
b may be connected to the upper chamber 4a. In this case, the cleaning agent 2 passes through the inside of the vertical container 7 upward from the lower end.
Since the article to be washed a is made to flow, the washing property is improved. In this case, a mesh member 18 can be provided at the upper end of the vertical case 7 for the purpose of preventing the outflow of the article a to be cleaned and preventing the vertical case 7 from floating.

That is, FIG. 3 is a diagram showing the outward path 3 of the liquid circulation line 3 of FIG.
a and a return path 3b, and an outward path 3c and a return path 3d as the liquid circulation line 3 are further added. In addition, outbound trip 3
A valve V8 is provided at c, and a valve V9 is provided at the return path 3d. Here, the forward path 3a and the return path 3b are used when the detergent 2 is forcibly circulated in the vertical container 7 in the vertical direction. Used for forced distribution.

間隔である。According to such a cleaning method in which the forced circulation direction of the cleaning agent is switched at least once, compared with the case where the cleaning agent 2 is forcedly circulated only from one direction, the cleaning agent 2 can be transferred to the object a to be cleaned. The contact of the cleaning agent 2 is multifaceted, the cleaning efficiency is improved, and it is effective for cleaning with a high degree of cleaning in a short time. In particular, in the case of an article in which certain surfaces of the object to be cleaned a are overlapped with each other and are closed, a slight difference in the distance between the gaps can effectively clean the object from the opposite direction.
In addition, depending on the type of the object a to be cleaned, the cleaning agent 2 floats during cleaning in which the cleaning agent 2 flows downward and upward, thereby improving the cleaning efficiency. The number of times of switching is not particularly limited and is performed at least once, but it is usually preferable to perform the switching about 2 to 4 times. The switching time is usually about 1 to 10 minutes.
