Hollow louvered glass window

Abstract

The invention discloses a hollow louvered glass window. The window comprises an upper frame structure, a lower frame structure and a Venetian blind, the Venetian blind comprises multiple louvers, ladder ropes, a floor beam, a turnover mechanism and a contracting and releasing mechanism, the ladder ropes comprise the left vertical ladder rope and the right vertical ladder rope, the hollow louveredglass window further comprises a second electromagnet block, a second iron block, a first electromagnet block and a first iron block, the louvers at least comprise the horizontal position, the first tilted position and the second tilted position, the first electromagnet block is used for conducting energizing when the louvers are located at the first tilted position to generate an attracting magnetic field to make the space of the left vertical ladder rope and the second vertical ladder rope become smaller so as to make the louvers transferred to the second tilted position from the first tilted position. The hollow louvered glass window is simple in structure, and the shielding property of the hollow louvered glass window can be effectively improved.

Description

technical field [0001] The invention relates to the fields of building sunshade and exterior windows, in particular to a hollow shutter glass window. Background technique [0002] In the southern part of my country, due to the high energy consumption of building cooling caused by solar radiation in summer, power cuts in summer have become the norm, seriously affecting people's lives and social and economic development. Setting movable external shading or movable central shading on the external windows of buildings can effectively reduce the energy consumption of air conditioning in summer. At present, more and more construction projects are equipped with external windows with shading devices. The movable external sunshade venetian blind is the most widely used sunshade product in the movable external sunshade system. It has dual functions of sunshade and dimming. The built-in sunshade louver hollow glass is the most widely used sunshade product in the movable central sunshad...

AI Technical Summary

Problems solved by technology

[0003] But at present, whether it is an external sunshade venetian blind or a hollow louver glass (also known as a built-in sunshade louver hollow glass), its shielding performance is poor, and its heat insulation performance is average. This is because the existing venetian blinds use ladder ropes to control the louvers Inclination, when the louvers are in the full sunshade position, the degree of closure between the louvers is not enough, the louver rotation angle is generally between 65° and 72°, especially in the lower area of ​​the venetian blinds, due to the more obvious gravity of the louvers, the louvers in this area The corner angle is the smallest, generally around 65°, more scattered sunlight enters the room, and the shading is poor, which reduces the heat insulation effect and privacy of the product. The louver system with poor shading performance reduces the shading effect by more than 30%.

[0004] In order to improve the shielding performance of venetian blinds, the patent No. ZL201210554094.2, titled "A movable sunshade louver system for building exterior windows" discloses a movable sunshade louver system for building exterior windows. An L-shaped positioning piece is fixedly installed at the node to increase the inclination of the venetian blinds. Although the shielding performance of the venetian blind is effectively improved, the thickness of the L-shaped positioning piece will increase when the ladder rope is folded, which will affect the aesthetics. The technology is only suitable for S-shaped louvers. For the most widely used single-arc louvers, there is no technology to improve the shielding performance
