A motor-vehicle heating and/or air conditioning device has a cold-air duct (12), a hot-air duct (14) housing a heating radiator (18), a mixing chamber (28) communicating with respective air outlets (24, 26) of the ducts, and mixing means which comprise at least one flap (30) configured in such a way

A motor-vehicle heating and/or air conditioning device has a cold-air duct (12), a hot-air duct (14) housing a heating radiator (18), a mixing chamber (28) communicating with respective air outlets (24, 26) of the ducts, and mixing means which comprise at least one flap (30) configured in such a way that, when the flap passes from a "hot" position to a "cold" position, the shutter wall (34) of the flap first of all clears a region of the outlet (24) of the cold-air duct which is close to the outlet (26) of the hot-air duct, so as to promote the mixing of a cold airflow (F1) and of a hot airflow (F2).

1. A motor-vehicle air conditioning device comprising a cold-air duct, a hot-air duct housing a heating radiator, a mixing chamber communicating with respective air outlets of said ducts, and mixing means suitable for controlling said air outlets in chosen proportions so as to set the temperature of the air in the mixing chamber, wherein the mixing means comprise at least a main flap and a first auxiliary flap, each including a shutter wall wherein when said flaps are spaced apart in a "cold position" the outlet of the hot-air duct is closed, and when said flaps are brought together to contact each other in a "hot position", the outlet of the cold-air duct is closed, and wherein said main and first auxiliary flaps are mounted pivoting about a spindle, said device further comprising a second auxiliary means suitable for closing the hot-air duct when the main flap and first auxiliary flaps are in the "cold" position, wherein the second auxiliary means comprises a flap that is housed in the hot-air duct, upstream of the heating radiator, and wherein the main flap is a drum flap and the second auxiliary means is a butterfly flap.
