Title:
VENTILATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/053696
Kind Code:
A1
Abstract:
There is a demand to simplify a structure for switching between air supply and air discharge. This ventilation device comprises a ventilation fan, a jetting switching mechanism (33), a first switching mechanism (34), and a control unit. The jetting switching mechanism (33) is capable of switching between a first state in which a ventilation hose is allowed to communicate with the ventilation fan (32) but a second opening is not allowed to communicate with the ventilation fan (32), and a second state in which the second opening is allowed to communicate with the ventilation fan (32) but the ventilation hose is not allowed to communicate with the ventilation fan (32). The first switching mechanism (34) is capable of switching between a third state in which a third opening (31c) for allowing communication between a flow-through space and the ventilation hose in a manner that bypasses the ventilation fan (32) allows communication between the flow-through space and the ventilation hose, and a fourth state in which the third opening does not allow communication between the flow-through space and the ventilation hose. The control unit sets the jetting switching mechanism (33) in the first state and sets the first switching mechanism (34) in the fourth state to carry out an air supply operation. The control unit sets the jetting switching mechanism (33) in the second state and sets the first switching mechanism (34) in the third state to carry out an air discharge operation.
