Energy-saving silent heat insulation fresh air system integrated doors and windows

Abstract

The invention discloses an energy-saving silent and heat-insulating fresh air system integrated door and window, relates to the technical field of building door and window ventilation, and comprises a door and window outer frame and an inner support frame movable window sash arranged inside the door and window outer frame. There is a ventilation mechanism for indoor and outdoor air replacement; a sealing mechanism for the ventilation switch of the ventilation box is installed in the ventilation cavity; a blocking mechanism for sound insulation and heat insulation is installed between the limit frame and the noise reduction plate; There is a transmission assembly for the switch of the blocking mechanism between the mechanism and the blocking mechanism; the present invention cooperates with the blocking mechanism, the blocking mechanism and the ventilation mechanism to facilitate the indoor air replacement and circulation operation when the window is closed, and through the blocking mechanism It can greatly improve the sealing performance of the device after the ventilation is stopped, facilitate the improvement of the overall silent and heat insulation effect of the device, and solve the problem that the indoor air cannot be replaced and circulated when the existing doors and windows are inconvenient to open in rainy weather.

Description

technical field [0001] The invention relates to the technical field of building door and window ventilation, in particular to an energy-saving type integrated door and window of a silent and heat-insulating fresh air system. Background technique [0002] With the continuous development of science and technology, the structure of the window is diversified, and the function of the window is more and more; the traditional window realizes the exchange of the air in the room and the outdoor air by opening the window; [0003] However, the movable sash of the window of this structure needs to be closed in rainy days to prevent outdoor rainwater from entering the room, causing the indoor air to fail to circulate and replace with the outdoor air through the window in rainy days, resulting in poor indoor air quality; The air exchange rate of the windows with this structure is far from enough when the window is opened, and it is difficult to complete the renewal of the air in the room...

AI Technical Summary

Problems solved by technology

[0003] However, the movable sash of the window of this structure needs to be closed in rainy days to prevent the outdoor rainwater from entering the room, causing the indoor air to fail to circulate and replace with the outdoor air through the window in rainy days, resulting in poor indoor air quality; The air exchange speed of the window with this structure is far from enough when the window is opened, and it is difficult to complete the renewal of the air in the room in a short time; therefore, the above-mentioned problems need to be improved.
