PURPOSE: An air conditioning device for vehicles is provided to prevent foreign materials in outdoor air from flowing into an air conditioning case with a cyclone dust collector, thereby preventing the contamination of an air filter due to the inflow of the foreign materials. CONSTITUTION: An air conditioning device for vehicles has a cyclone dust collector(50) comprised of a casing(52), a rotating air current guider(56), an air guiding unit, and a connection duct(80). The casing has a dust collecting chamber(52a) and an outdoor air outlet(52c). The rotating air current guider guides outdoor air toward the inner circumference of the dust collecting chamber to form rotating air current. Foreign materials in the outdoor air flowing into the dust collecting chamber of the casing are centrifugally separated. The air guiding unit guides the rotating air current to the outdoor air outlet. The connection duct connects the outdoor air outlet and an outdoor air inlet of an air conditioning case(10) so that the outdoor air guided to the outdoor air outlet can flow into the air conditioning case. |
