Claims

[Claims for Utility Model Registration] A heater core 3 that heats the air passing through the unit case 2, a detour 4 that bypasses the heater core 3, and a detour 4 that is provided upstream of the heater core 3 and that allows the air to pass through the heater core 3. and a mixing chamber 6 formed in the downstream area of the detour path 4 to adjust the ratio between the amount of air passing through the detour path 4 and the amount of air passing through the detour path 4; a distributor 33 that distributes air to an air outlet provided in the front, a defroster 14 that opens toward the inner surface of the windshield, a foot opening 16 that opens toward the passenger's feet, and an instrument panel in front of the driver's seat. a center vent port 10 provided in the center of the instrument panel 9;
Side vent ports 12, 12 provided on both sides of the
, a center vent port shut valve 24 that opens and closes the center vent port 10, a side vent port shut valve 25 that opens and closes the side vent port 12, and air that flows into the unit case 2 or passes through the detour path 4. An air conditioner for an automobile includes a cold air outlet 26 for taking out air, which includes: a defroster outlet 7 for blowing air mixed in the mixing chamber 6 to the defroster 14; and a foot duct for blowing air to the foot opening 16. Air outlet 8
and a side vent duct outlet 13 that blows air out to the side vent port 12 are formed in the distributor 33, and only the differential duct outlet 7 and the foot duct outlet 8 have air outlets 7, 8. A differential door 20 and a foot door 21 are provided to open and close the cold air outlet 26 and the center vent 1, respectively.
1. An air conditioner for an automobile, characterized in that the air conditioner communicates with 0 through a cold air bypass duct 32.
