Technical Field

[0001] The invention relates to the technical field of casement windows, and in particular to a novel double-broken-bridge casement window. Background Art

[0002] At present, one of the most commonly used windows in residences is the casement window. The window sash of the casement window opens and closes along a certain horizontal direction, so it is called a "casement window". Casement windows are divided into sliding and top-hung types. Its advantages are that it has a large opening area, good ventilation, and its sealing, sound insulation and heat preservation performance are better than sliding windows.

[0003] However, the casement window structure in the prior art is relatively simple, and its waterproof, wind-resistant and pressure-resistant properties are relatively poor, and its air tightness still needs to be improved. In addition, there are problems such as easy dust accumulation after long-term use. Summary of the invention
