AIR PURIFIER COMPRISING PURIFICATION AND VENTILATION MOTOR FOR ROTATING PURIFICATION AND VENTILATION FAN AND EXHAUST MOTOR FOR ROTATING EXHAUST FAN

摘要

PURPOSE: To provide an air purifier which is able to decrease vibration and noise generation of a driving motor and a ventilation fan. CONSTITUTION: A main body (10) comprises an exhaust flow path (30) that guides indoor air to the outdoor during a ventilation operation, an inhalation flow path (40) that guides outdoor air to the indoor during the ventilation operation, and an air-purification flow path (50) which inhales the indoor air, includes a filtering device (20) to separate contaminants from the air, and then guides the purified air to the indoor space during an air-purification operation. In the middle of the exhaust flow path, an exhaust motor (71) to generate rotation force and an exhaust fan (70) that is rotated by the exhaust motor and generates ventilation force to allow the indoor air to be flown-in along the exhaust flow path are equipped. In the middle of the inhalation flow path, a purification and ventilation motor (61) to generate rotation force and a purification and ventilation fan (60) that is rotated by the purification and ventilation motor and generates ventilation force to allow the outdoor air to be flown-in along the inhalation flow path are equipped.
