Abstract:
A multi-mode ventilation purifier. The ventilation purifier is divided by a middle partition plate (9) into a mechanical ventilation housing and a natural ventilation housing. The mechanical ventilation housing comprises, sequentially from bottom to top, a mechanical fresh air inlet (17), a prefilter (5), a leadscrew slide platform A(27), an indoor seal door A(4), an air grille C(12), a centrifugal fan (3), a high efficiency filter (2), and an air grille A(1). The natural ventilation housing comprises, sequentially from bottom to top, a natural fresh air inlet (16), an airflow regulating plate (11), a leadscrew slide platform B(25), an indoor seal door B(10), an air grille D(14), a leadscrew slide platform C(8), a bypass door (28), a medium efficiency filter (7), and an air grille B(6). The ventilation purifier has multiple modes comprising two natural ventilation modes and three mechanical ventilation modes. A ventilation mode and an air volume are automatically selected by means of a control panel according to indoor and outdoor air quality and ventilation requirements. Multiple modes of ventilation allow ventilation to consume less energy, and extend the service life of the ventilation purifier.
