PURPOSE:To improve the function of a side defroster, by constituting a device such that an auxiliary duct opened to a side ventilator nozzle is mounted downstream from a heater core, and during control of the defroster, a hot air is blown off from the side defroster and a side ventilator. CONSTITUTION:With a mode control lever shifted to a defrost position, a mode door 11 is opened to the opening part 14 side to its full capacity, and an opening 13 is closed to its minimum. Hot air, fed in from an air intake box 5 and flowing through a heater core 8, flows through the opening 14 and a defroster duct 18 and is blown off through a defroster nozzle 4 and a side defroster nozzle 20. In which case, hot water is also blown off through a side ventilator nozzle 3 after flowing through an opening 31 and an auxiliary duct 30. This constitution enables hot water to be simultaneously blown off through the side ventilator nozzle 3 and the side defroster nozzle 20, increases the amount of hot water fed to a side window, and improves the function of a defroster. |
