【発明の名称】乾燥機
Document Type and Number:
Japanese Patent JP2902902
Kind Code:
B2
Abstract:
PURPOSE:To get immediately rid of a danger of explosion in case a microcomputer malfunctions, a cooler does not work on a circulation drying route and a heater does not stop working. CONSTITUTION:There is a temperature switch 24 at the understream of a heater 6. When a cooler 16 does not work while drying is carried out by a circulation drying route due to a malfunction of a microcomputer and the heater 6 does not stop working, a hot air temperature reaches an abnormal temperature, whereby the dryer is turned off. Based on this turn--off, the control system of the microcomputer against a changeover valve 20 is cut, an exhaust air drying route is formed by the changeover valve 20, and this changeover state is maintained. By the formation of the exhaust air drying route, a solvent gas concentration rapidly lowers, so that a danger of explosion is avoided.
