Document Type and Number:
Japanese Patent JP5247906
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a ventilator device that ventilates properly both at a low air volume and a high air volume, is reduced in size, minimizes the manufacturing cost, and performs ventilation for accurate detection of a ventilation volume.SOLUTION: The ventilator device includes: a preceding air blower (first air blower) 6 and a succeeding air blower (second air blower) 9 which are disposed in series within an air passage; a rotation detector 10 for detecting, when the preceding air blower 6 is in an idling mode, the rotation of the blades of the preceding air blower 6 rotated by the air distributed through the air passage; a ventilation cross-sectional area adjuster 3 for varying a ventilation cross-sectional area in the air passage; and a ventilator device controller 24 configured to control the blade rotation of the succeeding air blower 9 so that the blade rotation of the preceding air blower 6 during an idling mode reaches a predetermined rotation, and control, when the succeeding air blower 9 is in a driving mode, the ventilation cross-sectional area adjuster 3 to maximize a ventilation cross-sectional area.
