摘要

PURPOSE: To provide an air purifier which is able to purify air at two indoor spaces, allow either outdoor air or the other indoor space's air to be flown in to ventilate the indoor spaces, and constitutes an inner flow path to be bilaterially symmetrical structure. CONSTITUTION: A first outdoor port (15), a first outdoor exhaust port (17), a second outdoor port (16), a second outdoor exhaust port (18), a first outdoor port damper (23), a first outdoor exhaust port damper, a second outdoor port damper (24), and a second outdoor exhaust port damper are placed at a rear side of a main body (10). A first indoor port (19), a first indoor exhaust port (21), a second indoor port (20), a second indoor exhaust port (22), a first indoor port damper (29), a first indoor exhaust port damper (31), a second indoor port damper (30), and a second indoor exhaust port damper (32) are respectively placed at both sides of the main body. A first ventilation fan (36), a second ventilation fan (37), and a heat exchange element are installed inside of the main body, where the first ventilation fan and the second ventilation fan are divided by a first partition plate (40). A direction converting damper is placed between the heat exchange element and the front side of the main body. A first medium performance filter (25) and a second medium performance filter (26), a first high performance filter (33), and a second high performance filter (34) are respectively placed at the first and second outdoor ports, and the first and second indoor exhaust ports.
