Claims

[Claims for Utility Model Registration] (1) A heater core 23 that heats the air from the cooler unit 13, a detour 24 that bypasses this heater core 23, and an amount of air passing through the heater core 23 and passing through the detour 24. A rotatable air mix door 25 that adjusts the ratio of air volume to
In the heater unit of an automotive air conditioner, the detour path 24 is formed between the heater core 23 and the heater core 23, in which a distributor 48 through which air from the unit body 47 flows is connected to a unit body 47 having a heater core 23. At the same time, a communication portion 57 is provided on one side wall 53 of the unit main body 47, which is substantially parallel to the flow direction of the mainstream air flowing down from the cooler unit 13.
, 70, and a portion of the air that has passed through the heater core 23 is transferred from a portion of the one side wall 53 that is downstream of the communication portions 57, 70 in the flow direction of the mainstream air. A heater unit for an air conditioner for an automobile, characterized in that a hot air bypass passage 83 for flowing down into the distributor 48 is defined in the unit main body 47. (2) The hot air bypass passage 83 has one end 82a.
is defined by a partition plate 82 connected to a portion of the one side wall 53 on the downstream side of the communication portions 57 and 70 in the flow direction of the mainstream air, and
A hot air inlet 84 that takes in a portion of the air that has passed through the heater core 23, and a hot air outlet 8 that blows out the taken air into the distributor 48.
5. A heater unit for an air conditioner for an automobile according to claim 1, comprising:
