Novel door/window with hidden drainage structure

Abstract

The invention discloses a novel door / window with a hidden drainage structure. The novel door / window comprises a window frame, a sash frame, a wooden molding and hollow glass. The outdoor wall of a lower frame bar of the window frame is provided with an inverted-L-shaped extension portion. The longitudinal section of the inverted-L-shaped extension portion is inverted L shaped. A gap is arranged between the inverted-L-shaped extension portion and the outdoor wall of the lower frame bar, and the inverted-L-shaped extension portion blocks an outflow channel opening arrange at the lower frame bar. The inside of the inverted-L-shaped extension portion is communicated with the inside of the window frame through the outflow channel opening. A skew fillet is correspondingly arranged below an opening formed between the inverted-L-shaped extension portion and the outdoor wall of the lower frame bar. The novel door / window has the advantages that the inverted-L-shaped extension portion blocks the outflow channel opening, unsmooth rain drainage and rain backflow are solved, and hidden drainage is achieved as the inverted-L-shaped extension portion blocks the outflow channel opening arranged at the lower frame bar.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a novel door and window with a hidden drainage structure. Background technique [0002] At present, there are more and more types of doors and windows on the market, including pure wood doors and windows, aluminum alloy doors and windows, plastic steel doors and windows, wood-clad aluminum doors and windows, aluminum-wood composite doors and windows, broken bridge aluminum alloy doors and windows, etc. Among these different types of doors and windows, large The opening method of most doors and windows adopts casement opening and casement interior. Generally speaking, the water tightness of outer casement doors and windows is better than that of inner casement doors and windows, while the water tightness of inner casement doors and windows is poor. In order to further improve the water tightness of doors and windows, the current drainage method of inner casement doors an...

Problems solved by technology

Generally speaking, the water tightness of outer casement doors and windows is better than that of inner casement doors and windows, while the water tightness of inner casement doors and windows is poor. In order to further improve the water tightness of doors and windows, the current drainage method of inner casement doors and windows is There are several water outlet slots directly milled on the lower frame outside the window frame, and the water outlet slots are all exposed to the outside world. The advantage of this process is that the process is simple, but the disadvantage is that the watertightness of doors and windows is still poor, especially when the outside In the case of heavy rain or high wind pressure, it is easy to have poor rainwater discharge and backflow, and it is also easy to cause blockage of the water outlet slot, which is very unsightly

[0003] In order to effectively alleviate the poor sealing performance of existing inner casement doors and windows in the market, especially the problem of poor water tightness, a new type of door and window with a hidden drainage structure that can improve the overall water tightness of doors and windows is proposed
