    • In a blower unit for a vehicle air conditioner, an inside/outside air switching door opens an inside air introduction port and closes an outside air introduction port when an inside air introduction mode is set. Plural ribs for irregularly reflecting an air-blowing noise generated by a blower fan are provided on an inner surface of the inside/outside air switching door, and top ends of the ribs are arranged along a main flow of inside air introduced from the inside air introduction port during the inside air introduction mode. Thus, the blower unit effectively reduces a reflected noise on the inner surface of the inside/outside air switching door, and effectively prevents a disturbance noise of the main flow of inside air.
    • 在用于车辆空调的吹风机单元中,当设置内部空气引入模式时,内部/外部空气切换门打开内部空气引入口并关闭外部空气导入口。 在内侧/外侧空气切换门的内表面上设置有用于不规则地反射由鼓风机风扇产生的吹风噪声的多个肋,并且肋的顶端沿着从内部空气引入的内部空气的主流 引入端口在内部空气引入模式。 因此,鼓风机单元有效地减少内/外空气切换门内表面的反射噪声,有效地防止内部空气主流的干扰噪声。

    • In a vehicle air conditioner, inside air and outside air are switched by first and second inside/outside air switching doors. The first inside/outside air switching door is operated by a first door lever operatively linked with an inside/outside air operation member of an operation panel. On the other hand, the second inside/outside air switching door is operated by a second door lever which is operated by a mode operation lever operatively linked with a mode operation member of the operation panel, a temperature-adjustment operation lever operatively linked with a temperature-adjustment operation member of the operation panel, and an elastic force of a spring. When an air outlet mode except for a defroster mode is manually set by the mode operation member, and when maximum heating is manually set by the temperature-adjustment operation member, the second inside/outside air switching door is operated to an inside air introduction state by the second door lever.
    • 在车辆空调中,内外空气通过第一和第二内/外空气切换门来切换。 第一内/外空气切换门由与操作面板的内/外空气操作构件可操作地连接的第一门杆操作。 另一方面,第二内/外空气切换门由第二门杆操作,第二门杆由与操作面板的模式操作构件可操作地连接的模式操作杆操作,温度调节操作杆可操作地连接到操作面板 操作面板的温度调节操作构件和弹簧的弹力。 当通过模式操作部件手动设定除霜除雾器模式以外的出风口模式时,当由温度调节操作部件手动设定最大加热时,第二内/外空气切换门被操作到内部空气导入状态 由第二门杠杆。
