Claims

[Scope of utility model registration request]

It is equipped with an intake unit 1 that takes in inside air and/or outside air, and a heater unit 3 having an outlet for distributing the inside and outside air into the vehicle interior, while supplying cooling water for the engine E into the heater unit 3. and a heater core 7 through which hot water circulates by connecting a hot water supply path 13 having a hot water valve 8 to a hot water return path 14 that returns the cooling water to the engine E, and a detour path 15 through which the introduced air bypasses the heater core 7. and a mix door 9 which is rotatably provided upstream of the heater core 7 and adjusts the ratio between the amount of air passing through the heater core 7 and the amount of air passing through the detour 15. In an air conditioner for an automobile that opens and closes the mixer door 9 and the hot water valve 8 by operating a template lever 17 to adjust the temperature of the blown air, when the template lever 17 is in low conditioning, the mixer door 9 closes the mixer door 9 and the hot water valve 8. At the same time, the hot water valve 8 operates according to the set temperature to open a part of the hot water supply path 13, and when the temperature lever 17 is in the middle mode, the mix door 9 closes at the set temperature. In response to this, the heater core 7 is rotated to an intermediate position in which a portion of the heater core 7 is opened, and the hot water valve 8 is operated in accordance with the set temperature to open a portion of the hot water supply path 13, and the temperature lever 17 is raised to a high temperature. At the time of harmonization, the mix door 9 rotates according to the set temperature to a position B where the entire heater core 7 is opened, and then to an intermediate position where a part of the heater core 7 is further opened. Supply route 1
3. An air conditioner for an automobile characterized by completely opening the air conditioner.
