To provide a fluid-soaking device 1 for heating workpiece 2 by electromagnetic induction heating and coating the workpiece 2 which satisfies a request for coating time and coating thickness, even when the workpiece 2 has a complicated shape without increasing output of a power supply device 12.SOLUTION: In a device 1, a tank 5 has a storage space where a powder coating is stored, and a bottom side of the storage space is partitioned by a porous wall 3 composed of a porous material. Fluidizing means 6 jets gas upward from the porous wall 3, and thereby forms a fluidized bed of the powder coating in the storage space 5a. A coil 7 is energized and controlled so as to pass a magnetic flux in the storage space, and heats the workpiece 2 by electromagnetic induction heating in a state in which the workpiece 2 is immersed in the fluidized bed. A robot 8 holds the workpiece 2, immerses the workpiece 2 in the fluidized bed, and changes the attitude and the position of the workpiece 2 with respect to the coil 7.SELECTED DRAWING: Figure 1 【課題】電磁誘導加熱によりワーク２を加熱して塗装する流動浸漬装置１に関し、電源装置１２を高出力化することなく、形状が複雑なワーク２でも、塗装時間や塗装厚さに対する要求を満たすようにする。【解決手段】装置１によれば、タンク５は、粉体塗料を貯留する貯留空間を有し、貯留空間の底側を、多孔質の材料からなる多孔壁３により区画される。また、流動手段６は、多孔壁３から気体を上向きに噴出することにより、貯留空間５ａに粉体塗料の流動層を形成する。また、コイル７は、貯留空間に磁束を通すように通電制御され、ワーク２を流動層に浸漬した状態で電磁誘導により加熱する。さらに、ロボット８は、ワーク２を保持するとともに流動層に浸漬させ、コイル７に対するワーク２の姿勢や位置を変化させる。【選択図】図１
