A ventilated glass heat-insulating window

Abstract

A ventilative heat-insulating glass window comprising a window frame (1); a primary window sash is disposed in the window frame (1); a secondary window sash (4) is disposed in a primary sash frame (2) of the primary window sash; a cavity (6) is provided between the primary window sash and the secondary window sash (4); an air inlet (11) connecting the cavity (6) and the outside of the window frame (1) is disposed at the bottom of the primary sash frame (2); an air outlet (7) connecting the cavity (6) and the inner and outer side of the window frame (1) is disposed at the top of the primary sash frame (2); a reversing valve (9) is disposed at the intersection of the cavity (6) and the air outlet (7). The heat-insulating window is ventilative and efficient in energy-saving.

Description

technical field [0001] The invention relates to an improvement of the structure of a glass thermal insulation window. Background technique [0002] Existing windows are often incapable of ventilation when closed and are poorly insulated. [0003] The patents "Double-layer window with ventilation function 200880123426.9" and "Double-layer window with horizontal air convection function 200880123427.3" are two patents that set a fixed fan made of single glass on the outside of the opening fan of the insulating glass to form a second air cavity To achieve the effect of ventilation and heat insulation, but this makes the window lose the ability to actually open. [0004] In addition, when customers have more requirements for window functions, better energy saving and sound insulation performance, for example, they want to be able to shade the sun, but they don’t want the sun shading system to be installed externally, and they also want the sun shading system to be easily cleaned...

Problems solved by technology

[0003] The patents "Double-layer window with ventilation function 200880123426.9" and "Double-layer window with horizontal air convection function 200880123427.3" are two patents that set a fixed fan made of single glass on the outside of the opening fan of the insulating glass to form a second air cavity To achieve the effect of ventilation and heat insulation, but this makes the window lose the ability to actually open

[0004] In addition, when customers have more requirements for window functions, better energy saving and sound insulation performance, for example, they want to be able to shade the sun, but they don’t want the sun shading system to be installed externally, and they also want the sun shading system to be easily cleaned, maintained, and replaced. Ordinary Thermal break aluminum windows are not enough

The same built-in louvered hollow glass windows, because the louvers are placed in the hollow layer of the insulating glass, once there is a problem with the louver and needs to be repaired or replaced, the insulating glass must be destroyed or the entire replacement will be required. Triple-glazed window sash with built-in shutters CN 102518378 "Window shown in A")

[0005] In the window shown in the patent "A Triple Insulated Window with Built-in Shutter CN 101338646A", the built-in shutter is fixed together with the inner single glass window. After disassembly, it is still inconvenient
