塗膜表面に（２次）タレを生じるといった問題点がある
。However, if this electric@painting line is applied to objects such as automobiles that have seams,
Since the joints are not washed sufficiently with water, there is a problem in that the washing water containing the paint components in the joints is blown out during drying and causes (secondary) sagging on the surface of the finished coating film.
また、一方では塗膜の乾燥に必要な熱風を供給する乾燥

経済であるという問題点がある。On the other hand, in the drying equipment that supplies the hot air necessary for drying the paint film, exhaust gas is emitted which is replaced by the newly supplied gas in the combustion furnace (or heat exchanger), which is uneconomical. There is a problem.
［問題点を解決するための手段］
本発明者は上記した問題点を解決するために鋭意研究を
重ねた結果、乾燥炉からの排気ガスを利用した加温装置

Further, a fan may be provided in the middle of the duct 3 and connected to the duct 13. Further, in each duct, the duct 3 is connected to the washing water heating devices 1 and 2, the ducts 11 and 12 are connected to the suction device 15 of the drying chamber 17 through the fan 14, and the duct 13 is connected to the suction device 15 of the drying chamber 17 through the fan 14. Connected to the suction device 16, the duct 10 is connected to the combustion furnace 9. A part of the gas combusted in the combustion furnace 9 is used as a heat source to be supplied to the water washing device. Further, air is supplied to the heat exchanger 8 in an amount comparable to that of the gas supplied to the water washing device.

-The coated object was electrodeposited at 30°C.
After washing with spray water for 3 minutes at
A dry coating film was obtained by baking for 30 minutes at C. The appearance of the dried paint film was excellent, with no defects such as (secondary) sagging of the paint film, even in locations where the clearance of the joints of metal plates was 200 units or more. The gas burned in the combustion furnace is used to dry the paint film and maintain the temperature of the washing water, so there is no waste at all.
