<p>PURPOSE:To obtain a miniaturized and lightweight efficiently dehumidifying device and to reduce noise, by constituting a cooling device with a module gathering plural Peltier effect elements and controlling the electric current flowing to the module according to the temp. of the module. CONSTITUTION:When electric current is supplied to the modules 10, 11 consisting of the Peltier effect elements and to a fan 18, the heat absorbing surface of the module 10 is cooled with a result that fins 12 are cooled, and the vapor in the air flowing through a wind passage 5 is condensed into water drops sticking to the surface of the fin 12. The air having passed through the fin 12 is heated when it passes through the fin 13 of the module 11 connected with a heat pipe 14, and is discharged from a blow-out opening 4. The temp. on the heat absorbing surface side is detected by a thermistor 19. When the thermistor 19 detects frosting, the output power of a comparator in a control circuit is reversed to reduce the electric current flowing to the module 10, so that the dehumidification is continued with a slightly reduced dehumidifying capacity.</p> |
