ABSTRACT:
A core unit of a dehumidifier comprises two towers and an upper and a lower air valve. The two towers are mounted in parallel between the upper and lower air valves and respectively filled with a drying agent. Two control valves are respectively connected to the corresponding tower through the lower air valve. When pressurized air flows into the lower air valve, the lower air valve determines that the air go to one of the two towers linked to the other tower by an equalizing slot, causing a difference in air pressure between the two towers. When the air pressure of the two towers is equal, the lower air valve changes the tower to receive the pressurized air and allows the drying agent in the other tower to dry out. Therefore, the two towers generate dry air alternately whilst reducing manufacturing costs.
