Smart window with variable transmittance glazing

Abstract

A window includes: a window frame having an opening defined therein through which an outdoor space and an indoor space communicate with each other; a pair of sashes slidably disposed in the window frame and sliding in an opening direction and a closing direction opposite to the opening direction; a variable transmittance glazing configured to be fitted in the sash to open and close the opening together with the sash according to a sliding of the sash; the variable transmissivity window glass has a transmissivity which is variable through an electrical connection; a first conductive member disposed on the sash and electrically connected with the variable transmittance window glass to supply power to the variable transmittance window glass; and a second conductive member electrically connected to the first conductive member to supply power to the first conductive member from outside of the window frame.

Description

[0001] Cross-references to related applications [0002] This application claims priority to Korean Patent Application No. 10-2020-0107229 filed with the Korean Intellectual Property Office on Aug. 25, 2020, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to a window, and more particularly, to a smart window with variable transmittance glazing. Background technique [0004] Generally, a window frame in a wall of a building and a sash installed in the window frame are collectively referred to as a window. In recent years, smart windows consisting of window panes interposed with variable transmittance films have been developed. [0005] The transmissivity of the pane of a smart window is changed through electrical connections. Therefore, an electrical connection for controlling the transmittance is required. However, in the case of providing a separate fastening connector for electrical connection, t...

Problems solved by technology

However, in the case of providing a separate fastening connector for electrical connection, there is a risk of damage to the connector during opening and closing of the window, and deterioration of workability due to a separate design for overcoming the steps

[0006] In addition, since this window additionally requires components for electrical connection compared to existing windows, it may cause inconvenience during window assembly such as applying a sealant, and the airtightness of the window may not be possible due to steps, water leakage, etc. Keep

[0007] Also, where the components used for the electrical connection are exposed to the outside, the aesthetic aspect of the window may not be attractive
