Abstract

PURPOSE: To obtain a demister for a window glass and to simplify the mounting operation of the demister by comparing the saturated steam pressure at a surface temperature of window glass with the steam pressure of the air in a compartment and activating automatically the demister.
CONSTITUTION: Turning a starting key on causes a controller to be in operating condition and a digital operation device 5 resets a switch 4 of a hot-wire heater 2 to OFF. Each of the output signal from a humidity sensor 6 for detecting the humidity in a compartment, an iner temperature sensor 7 for measuring the temperature in the compartment, and an outer temperature sensor 8 for measuring the temperature outside the compartment is input to the operation device 5. The operation device 5 calculates the surface temperature of window glass in accordance with these signals to determine the saturated steam pressure at the temperature and also the steam pressure in the compartment. Then, the operation device 5 compares this saturated steam pressure with this steam pressure in the compartment, controlling the switch 4 of the heater 2 to set this switch to ON or OFF according to the result of the comparison and preventing the blur on the window glass.
