A DRYING MACHINE WITH THE OUTSIDE AIR ENTERANCE SWITCH

摘要

PURPOSE: A drying machine with an outside air inlet switch is provide to save energy consumed in a drying process, and to increase the drying efficiency and energy efficiency with an air inlet switch while enhancing dehumidifying efficiency. CONSTITUTION: An internal humidity sensor(11) measures humidity inside, and is installed on the top of a drying chamber(17). An external humidity sensor(12) is installed at the outside of a drier, and measures the humidity of the outside the drying chamber. An outside air entrance and exit port is opened when the humidity in the drying chamber is higher than the outer humidity of the drying chamber. An outside air inlet switch or a solenoid valve(14) is used to close the outside air entrance and exit port. A control part controls the outside air inlet switch or the solenoid valve automatically.
