Claims

[Claims for Utility Model Registration] A heater core 23 that heats the air from the cooler unit 13, a detour 24 that detours around the heater core 23, an amount of air passing through the heater core 23, and an amount of air passing through the detour 24. The unit body 47 has a rotatable air mix door 25 that adjusts the ratio between the unit body 4 and the unit body 47.
Distributor 48 through which air from 7 flows down
In the heater unit of an air conditioner for an automobile, the seal ribs 55a and 55b which come into contact with the edge of the air mix door 25 which has been rotated to the position where the detour path 24 is closed to prevent air leakage are attached to the heater unit. Provided in the main body 47 and communicating with one side wall 53 of the unit main body 47, which forms the detour path 24 between the heater core 23 and is substantially parallel to the flow direction of the mainstream air flowing down from the cooler unit 13. Section 57
, 70 to connect the distributor 48 to the opening inner peripheral edges 57a to 5 of the communicating portions 57, 70.
7d, a first inner circumferential edge 57a and a second inner circumferential edge 57 located in a direction perpendicular to the flow direction of the mainstream air on the opening surface of the communication portions 57, 70.
The seal rib 55a,
A part of the air passing through 55b is transferred to the inner peripheral edge 5 of the opening.
A heater unit for an air conditioner for an automobile, characterized in that cold air guide ribs 66 and 67 are provided to guide the cold air to the vicinity of a third inner circumferential edge 57c located downstream of the mainstream air among the air conditioners 7a to 57d.
