Door and window with air supply device

Abstract

The invention discloses a door and window with an air supply device. The door and window comprises a window frame and a glass surface, a ventilation plate is arranged at the top end of the window frame, a ventilation hole is formed in the middle of the ventilation plate, a pressurizing chamber is further formed in the ventilation plate, a pressurizing fan is arranged in the pressurizing chamber, a plurality of air inlets are formed in the side wall of the pressurizing chamber, a first pressurizing air duct is arranged in the ventilation plate around the ventilation hole, a ventilation annular groove is further formed in the inner wall of the ventilation hole, and the first pressurizing air duct communicates with the pressurizing chamber. According to the scheme of the door and window with the air supply device, by arranging the pressurizing chamber, air can be pumped into the room from the air inlet through the pressurizing fan and then blown into the room from the ventilation annular groove, and a gap between the ventilation annular groove and the first pressurizing air duct is set to be a small gap, so that the air outlet speed is increased; and through high-air-speed airflow, outside airflow of the ventilation opening can be driven to enter the room, meanwhile, indoor air circulation is improved, the ventilation efficiency is greatly improved, and the ventilation effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of door and window structures, in particular to a door and window with an air supply device. Background technique [0002] Doors and windows are divided into enclosure components or partition components according to their positions, and have different design requirements to have functions such as heat preservation, heat insulation, sound insulation, waterproof, and fire prevention. The new requirement is energy saving. The lost heat accounts for about 25% of the total heating heat consumption. Now many people install double-glazed doors and windows. In addition to enhancing the effect of heat preservation, a very important role is sound insulation. The prosperity of the city, the density of living, and the status quo of developed traffic make the effect of sound insulation more and more popular. [0003] When the existing doors and windows need to be ventilated, the windows are mostly opened directly. When ...

AI Technical Summary

Problems solved by technology

[0003] When the existing doors and windows need to be ventilated, most of the windows are opened directly. When the living floor is high or the external environment is poor, the windows are not easy to open, which affects the indoor ventilation effect and is not easy to use.
