Abstract:
1. A motor-vehicle heating and air conditioning device comprising: a supply unit for suctioning and supplying air, a heating and air conditioning unit comprising a heater and an evaporator and a mixing lid for distributing the airflow coming from said supply unit between said heater and said evaporator, and means for distributing the airflow coming from said heating and air conditioning unit between one or more outlets distributed along a dashboard of the motor-vehicle, respectively adjacent to the windscreen, at the front on the dashboard or adjacent to the floor of the cabin of the motor-vehicle, to respectively actuate the DEFROST, VENT, or FLOOR functions, or their combination, wherein the abovementioned means for distributing the airflow between DEFROST, VENT, and FLOOR outlets are made up of a single moveable element having several operational positions, wherein said single moveable element has a substantially disc-shaped body, mounted rotating around its axis, and having two main opposite walls orthogonal to the abovementioned axis, a circumferential wall, and two radial end walls, said main opposite walls and said circumferential wall having apertures suitable to cooperate with corresponding inlets of pipes for conveying air to respective FLOOR, DEFROST, VENT outlets, wherein the abovementioned single moveable element has five operational positions, respectively corresponding to a sole actuation of the DEFROST outlets, a sole actuation of the VENT outlets, a sole actuation of the FLOOR outlets, a combined actuation of the VENT and FLOOR outlets, and a combined actuation of the DEFROST and FLOOR outlets, wherein said mixing member is rotatably mounted around an axis and has two opposite flat walls, orthogonal to said axis, in a form of circle sections, connected to each other by a peripheral curved wall which serves as a lid, wherein connected in an articulated manner to the mixing member is an end edge of a panel having, adjacent to an opposite end edge thereof, two side pins guided into shaped slots obtained in the walls of the body of the casing of the heating and air conditioning unit, and said mixing member has a first end position in which said panel leaves an access to the heater open for the airflow which has passed through the evaporator, and a second end position, in which said panel closes the access to the heater, while said curved wall closes the outlet downstream of the heater.
