Title: Cold air feeding device and cooling filter used in this cold air feeding device
Inventor: ITOU KATSUYUKI
IPC: F24F1/00
Filed: 1988-11-05
Abstract: PURPOSE:To eliminate a filter driving system, reduce the number of component elements and provide a cost down by a method wherein water is fed into a cooling filter by water feeding means and an air flow is discharged in a substantial parallel direction with the cooling filter. CONSTITUTION:Water is supplied from a water supplying tank to a water absorbing part 3. The water is sucked by a phenomenon of capilary action from a belt-like cooling filter 5 from the water absorbing part 3. As a motor is driven and a fan is rotated, air is taken from a rear surface of a main body of a cold air blower. The belt-like cooling filter arranged within a filter frame member 6 is arranged in substantial parallel with an air flow and then the air flow passes in a direction perpendicular to a longitudinal direction of the belt-like cooling filter 5. At this time, moisture content within the belt-like cooling filter 5 is evaporated, and evaporation heat is retrieved from the air stream. Thus, the cooled air stream is discharged out of an opening at the front surface. It is not necessary to provide a driving mechanism for rotating the cooling filter 5. The rotary driving source for the air blowing means may be made of a small-sized one and the number of the component elements is less and thus its cost can be reduced.
