Title:
VENTILATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/065680
Kind Code:
A1
Abstract:
Provided is a ventilation device (1), comprising a main body (2), a ventilation part (3), a dehumidifier part (4), a degree of moisture sensing part (9), and a control part (5). An intake port (10) and an exhaust port (11) are disposed on the main body. The ventilation part vents air from the intake port to the exhaust port. The dehumidifier part senses the degree of moisture of a subject of interest. The control part controls the venting from the exhaust port. The degree of moisture sensing part comprises a light emission part (7) and a photoreceptor part (8). The light emission part emits, toward the subject of interest, a sensing light including a wavelength absorbed by water, and a reference light including a wavelength less prone to be absorbed by water than the wavelength of the sensing light. The photoreceptor part receives the sensing light and the reference light, which have been reflected by the subject of interest. The control part comprises a degree of moisture computation part for comparing the intensities of the sensing light and the reference light received by the photoreceptor part and computing the degree of moisture. The control part controls the ventilation on the basis of the degree of moisture computed by the degree of moisture computation unit.
