Ventilating heat-insulating glass window

Abstract

The invention discloses a ventilating heat-insulating glass window, and relates to the improvement of a heat-insulating glass window structure. The heat-insulating glass window has a good heat-insulating effect, has a ventilating function, and can be opened. The ventilating heat-insulating glass window comprises a window frame, wherein a main window sash is arranged in the window frame. A structural key point is that a secondary window sash is arranged in a main sash frame of the main window sash, wherein a cavity is formed between the main window sash and the secondary window sash; an air inlet for communicating the cavity with the outer side of the window frame is formed in the bottom of the main sash frame; an air outlet for communicating the cavity with the inner and outer sides of the window frame is formed in the top of the main sash frame; a reversing valve is arranged at the intersection of the cavity and the air outlet.

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...

[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
