When the variable window-to-wall ratio adjustment device is activated, the reel and reel rotate to lift the first and second rows of insulation boards. The insulation boards, together with the baffle strips, cover the window opening, forming a combined enclosure structure with the insulation boards, a sealed air layer, and the exterior window, thereby significantly improving thermal insulation performance.

Description

Technical Field

[0001] The present invention relates to a variable window-to-wall ratio combined enclosure structure and an adjusting device thereof, specifically, a combined enclosure structure and an adjusting device thereof which can significantly improve the thermal insulation performance of exterior windows by adjusting the window-to-wall ratio. Background Art

[0002] External windows are the weak link in the thermal insulation of the building's exterior envelope. Compared with the exterior walls, their thermal insulation performance is only a fraction to one tenth. Currently, most building exterior windows use single- or double-chamber insulating glass with thermal insulation profiles for energy-saving windows. The heat transfer coefficient is generally not less than 2.0W / (m 2 ·K). To further improve the thermal insulation performance of exterior windows, the number of glass layers would need to be increased and better thermal insulation profiles would be used. This would significantly increase the cost while not significantly improving performance, resulting in a low cost-performance ratio and a low acceptance rate for users. Currently, some residents are spontaneously using so-called thermal curtains to protect themselves from the winter cold. These curtains are not true curtains, but rather roll-up curtains made of composite fabrics such as PVC (polyvinyl chloride) film, PEVA (polyethylene-vinyl acetate) film, or polyester fiber that are slightly larger than the window opening. These curtains are affixed around the interior window opening with adhesive-backed Velcro, creating a closed air layer with the exterior window. This provides some insulation, but the improvement in thermal insulation performance is minimal. Since the curtains are fixed to the window opening, they cannot be opened and closed flexibly as needed, which to some extent affects the normal use of the exterior window. Summary of the Invention

[0003] In response to the deficiencies of the prior art, the present invention provides a variable window-to-wall ratio combined enclosure structure and an adjustment device thereof. Specifically, a combined enclosure structure and an adjustment device thereof can significantly improve the thermal insulation performance of exterior windows by adjusting the window-to-wall ratio.
