Air compressor

Abstract

An air compressor comprises a compressing device driven by a motor, a heat exchanger cooling the first air compressed by the compressing device by the second air blowing from a blower, an intake path through which the first air sucked by the compressing device flows, a discharge path through which the second air blown by the blower and heated by the heat exchanger flows, and a dehumidifying rotor that carries an adsorbent adsorbing moisture from the first air, the moisture being removed by the second air to restore the adsorbent.

1 . An air compressor comprising:
 a motor;   a compressing device driven by the motor to suck and compress first air;   a blower blowing second air;   a heat exchanger cooling the first air transferred from the compressing device by second air blowing by the blower;   an intake path through which the first air sucked by the compressing device flows;   a discharge path positioned adjacent to the intake path, the second air heated by the heat exchanger flowing through the discharge path; and   a dehumidifying rotor disposed across the intake path and the discharge path and carrying an adsorbent adsorbing moisture from the first air sucked by the compressing device, the moisture being removed from the adsorbent by the second air.   
     
     
         2 . The air compressor of  claim 1  wherein the dehumidifying rotor comprises an adsorbing area and a restoration area partitioned from each other, the adsorbing area adsorbing moisture into the adsorbent from the first air sucked by the compressing device, the adsorbent being restored in the restoration area by the second air heated by the heat exchanger. 
     
     
         3 . The air compressor of  claim 1  wherein the adsorbent comprises silica gel. 
     
     
         4 . The air compressor of  claim 1  wherein the adsorbent comprises zeolite. 
     
     
         5 . The air compressor of  claim 1  wherein the dehumidifying rotor is rotated with a belt wound an outer circumference and driven by a motor via the belt.
