PURPOSE:To enhance comfortableness in a ventilator which contains the first wind path for natural wind and the second wind path for forced wind by connecting the second wind path between a branching part of the first wind path toward a person's breast and feet, and a vent port for breast via a change-over valve. CONSTITUTION:When a control lever 13 is moved to an A-mode position, a change-over valve 11 integrated with an arm member 12 is turned to a limited position of a stopper 20 to close the first wind path 5. On the other hand, a control valve 14 connected to the valve is forced counter-clockwise to close an upper branching path 7b and open the second wind path 10. Thereby, a forced air only is fed by an air conditioning unit from a vent port 2 for breast. At a B-mode position, the first wind path 5 opens to a vent port 8 for foot and the second wind path opens to the vent port 2 for breast, thereby achieveing a head- cool and foot-warm type cooling. At a C-mode position, the first wind path 5 opens to both the vent ports 2, 8 while a forced air from the second wind path 10 is not allowed to pass. Thereby, a natural air and the forced air may be effectively used. |
