Description of the Related Art Conventionally, a method of rinsing an electrodeposited article after electrodeposition coating in a dip rinsing tank has been performed according to the procedure shown in FIG. That is, as shown in FIG. 2A, washing water 21 is stored in a boat-shaped dip washing tank 20, and a plurality of electrodeposition-coated articles W, on which electrodeposition has been completed, are placed on a carrier 22 and continuously. The dip was washed in the washing tank 20 and then washed out.

As a result, coating film defects were caused. In addition, since foreign matters in the dip washing tank 20 gradually increase, it was necessary to periodically update the entire amount of the washing water 21. However, a large amount of washing water (for example, 100m
3 ) is stored, and as is clear from the side view of the dip washing tank 20 shown in FIG.
Since 3 is one place at the bottom of the tank, renewal of the rinsing water 21 has disadvantages such as that much time and cost are required.

FIG. 1 is a front sectional view a) and a side sectional view b) showing an example of a dip washing tank for washing electrodeposited articles according to the present invention. As shown in FIG. 1A, the upper part of the dip washing tank 1 of the present invention is boat-shaped like the conventional washing tank, but the bottom part has a completely different form as is clear from FIGS. are doing. That is, dip washing tank 1
A plurality of hoppers 3 of, for example, 2 to 5 are formed at the bottom of the hopper. At the tip of each hopper 3 is an outlet 4

における制約が多くなる。Here, the preferred shape of the hopper 3 will be described. The inclination angle of the hopper 3 is 2 degrees with respect to the horizontal direction.
0 ° or more is preferable, and 30-60 ° is more preferable. If the angle of inclination is too shallow, foreign substances settle and accumulate on the inclined surface, and the filtration efficiency of the foreign substances decreases. On the other hand, if the inclination angle is too deep, the capacity of the dip washing tank 1 becomes too large, or the depth of the dip washing tank 1 must be ensured, and restrictions on installation and the like increase.

The electrodeposition coated material W after the electrodeposition coating is finished,
After being placed on the carrier 5, it is successively put into the dip washing tank 1 and washed. Here, the electrodeposited coating material W
Is to pass through the upper layer water in which foreign matter of the washing water 2 stored in the dip washing tank 1 does not stay. The foreign matter washed off from the electrodeposition coating material W by the washing water 2 descends in the washing water according to its own weight, and gradually sinks in the plurality of hoppers 3 in the dip washing tank 1. Since the concentration of foreign matter in the upper layer water is sufficiently low, good cleaning can be performed.

Further, when the electrodeposition coating material W is an automobile body, only the lower half of the body including the locker portion is washed,
When performing a so-called half-dip, the condition may be such that the car body is half-submerged. The water used as the washing water 2 is not particularly limited, and may be, for example, pure water, industrial water, or tap water.

うことができる。According to the present invention, the dip rinsing tank for washing electrodeposited articles with water has a rectangular boat shape for allowing the electrodeposited articles to enter and leave the tank continuously. Are formed at the tip of each hopper, and foreign matters such as iron powder, paint agglomerates, and sealers that are washed off from the electrodeposited product accumulate at the tip of the hopper. Therefore, in order to discard the foreign matter in the washing tank, it is only necessary to open the discharge port, and it is not necessary to replace all the washing water in the washing tank as in the related art. In addition, since the amount of foreign substances to be discarded from the outlet and the amount of washing water discarded therewith are small, the discarding operation can be performed without stopping the water washing operation.

品の製造に好適である。According to the method for washing the electrodeposited article with water according to the present invention, foreign matter in the washing tank is removed by washing the electrodeposited article so as to pass through the upper water having a low foreign substance concentration. It is difficult to adhere and a high quality coating film surface can be obtained. Therefore, it is suitable for manufacturing automobile bodies, automobile parts, and other products by electrodeposition coating.
