Air duct structure attached to door and window auxiliary frame structure
Provided is an air duct structure attached to a door and window auxiliary frame structure. The door and window auxiliary frame structure is formed by an upper auxiliary frame section, a lower auxiliary frame section, a left auxiliary frame section and a right auxiliary frame section which are arranged and connected on the inner side wall of a door and window opening and mounted between the door and window opening and a door and window frame. At least one of the four auxiliary frame sections is an energy-saving auxiliary frame section. The energy-saving auxiliary frame section is formed by an outer section and an inner section which are connected through an insulating block between the outer section and the inner section. The inner section is provided with an inner notch. An air outlet section is of a non-fully enclosed section structure. The cross section of the air outlet section is composed of a cavity formed by a straight section and an arc-shaped section with an arc. The side surface of the arc-shaped section with the arc is fitted to the inner side wall of the inner section, the position facing a room, of the arc-shaped section is in 7-shaped edge banding, a gap is formed between the end surface of the 7-shaped edge banding and the side facing the room, of the end surface of the straight section on the opposite side, and the gap forms an air outlet connecting with the cavity, namely an air ventilation flow channel.
