<P>PROBLEM TO BE SOLVED: To provide a heat reflux drying machine which can recover heat by exchanging heat between cool air and hot air. <P>SOLUTION: An air inlet 101 is connected to an air intake flowpath 110. A heat refluxing device 102 has a pipeline segment 1029 having water condensing function. A pipeline segment outlet 1021, a returned hot air inlet 1022 and a cold/hot air mixing space 1023 connected to the pipeline segment outlet 1021 and the returned hot air inlet 1022 are provided. A fluid heating device 103 is provided between a heating space 104 and the cold/hot air mixing space 1023. An electric fluid pump 106 has a hot air pumping inlet 111. A fluid pipeline 1035 has a top/down bended flow guiding structure 1032 and has one end connected to the electric fluid pump 106. An external discharging port 109 is formed at the other end of the fluid pipeline 1035. An electronic control device 107 controls the fluid heating device 103 and the electric fluid pump 106. <P>COPYRIGHT: (C)2013,JPO&INPIT |
