も僅かながら行われる。Therefore, when the ventilation fan (10) operates, the air in the elevator car room is sucked into the suction portion (10b) of the ventilation fan (10) through the inlet (14) and the inflow path (12) (arrow (a), (Refer to (b)) Moreover, the air pressure-fed from the pressure feeding part (10a) of the ventilation fan (10) to the outflow passage (11) is introduced into the elevator car chamber through the outflow port (13) (arrow (c)). , (D)), which causes the air in the elevator car room to continuously circulate. During this circulating movement of air, a part of the air flows out to the outside through the gap (x) due to the pressure effect in the car chamber (see arrow (f)), and the outside air moves toward the suction part (10b). Is introduced into the elevator cab through the clearance (y) (see arrow (g)), so that the replacement of fresh air can be performed slightly.

It is operated by the inflow of air from the outside into the elevator car room (see arrow (h)) and the outflow of air from the car room to the outside (see arrow (i)). Then, this natural ventilation is generally carried out by convection based on the temperature difference of the air, and the cold air that has flowed in from the gap (x) is warmed and flows out from above the narrow gap (y) to the outside.
