A door and window with a ventilation device

Abstract

The invention discloses a door and window with an air supply device, comprising a window frame and a glass surface, a ventilation plate is arranged at the top of the window frame, a ventilation hole is arranged in the middle position of the ventilation plate, and a pressurizing chamber is also arranged on the ventilation plate to increase the A booster fan is arranged in the pressure chamber, a number of air inlets are arranged on the side wall of the pressure chamber, a first booster air duct is arranged inside the ventilation plate around the ventilation hole, and a ventilation ring groove is also arranged on the inner wall of the ventilation hole. The pressurizing air duct is communicated with the pressurizing chamber. In this scheme, through the setting of the pressurized chamber, air can be drawn in from the air inlet through the pressurized fan, and then blown into the room from the ventilation ring groove. The gap between the ventilation ring groove and the first pressurized air duct is set to a small gap, so as to The wind speed of the air outlet is increased, and the high-speed air flow can drive the outside air flow from the vent to enter the room, and at the same time improve the indoor air circulation, greatly improve the ventilation efficiency, and ensure the ventilation effect.

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 members or partition members according to their different positions. There are different design requirements to have functions such as heat preservation, heat insulation, sound insulation, waterproofing, fire prevention, etc. The new requirements are energy saving. The heat loss accounts for about 25% of the total heating energy consumption. Nowadays, many people install double-glazed doors and windows. In addition to enhancing the effect of thermal insulation, a very important role is sound insulation. The prosperity of the city, the density of living, and the current situation of developed traffic make the effect of sound insulation more and more popular.

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.
