Abstract:
A hygiene management device for an entrance hall and a control method of the same are proposed. The hygiene management device may be installed in the space of the entrance hall, and when the opening of an entrance door is detected, air is discharged toward the entrance door by tilting an air discharger toward the entrance door, and when the closing of the entrance door is detected, the air discharger is tilted to a preset initial position to stop the discharging of air. Accordingly, during the opening of the entrance door, the introduction of external air into the space of the entrance hall may be minimized.
