US 6,685,554 B2 · Air guide box

Abstract

An air guide box, in particular for a heating, air conditioning and/or ventilating installation in a motor vehicle, comprising at least an air treating device (10, 12), at least an air channel (20) extending through the air treating device (10, 12), and at least an air channel (30) bypassing the air treating device (10, 12) and at least two outlet channels (40, 50), emerging in a gap (3) such that each time an outlet channel (40, 50) is substantially opposite one of the other channels (20, 30), a device (1) mobile about an axis (2) being arranged in the gap (3), which device has an air guiding element in the form of a channel (4, 5, 6, 7) and provides, in specific positions, an air passage with practically no pressure drops between two mutually opposite channels (20, 40; 30, 50), and an air passage subjected to pressure drops between other opposite channels (30, 50; 20, 40).

Dependent claims

An air guide box, particularly for a heating, air-conditioning and/or ventilation system of a motor vehicle, comprising:

1. at least one air treatment device;
2. at least one air path extending across the air treatment device;
3. at least one air path bypassing the air treatment device;
4. at least two outlet paths which open into a space;
5. at least one air guiding element located in said space;
wherein when at least one of said outlet paths is substantially facing at least one of said air paths, said air guiding element allows, in defined positions, a first air passage with little to no loss of pressure between said face to face outlet path and said air path, and a second air passage with pressure drop between said facing outlet path and said air path.
