Aluminum alloy window frame drainage system capable of preventing rainwater from flowing backwards

Abstract

The invention belongs to the field of door and window drainage, and particularly relates to an aluminum alloy window frame drainage system capable of preventing rainwater from flowing backwards. The aluminum alloy window frame drainage system capable of preventing rainwater from flowing backwards comprises a window frame. A cavity is formed in the bottom of the window frame. The aluminum alloy window frame drainage system capable of preventing rainwater from flowing backwards is characterized in that a plurality of drainage openings are formed in the top of the cavity, a plurality of water outlets are formed in the portion, close to the portion below the outdoor side wall, of the cavity, and the drainage openings and the water outlets are formed in a staggered mode. According to the aluminum alloy window frame drainage system capable of preventing rainwater from flowing backwards, the structure is simple, the design is ingenious, the problem that rainwater in a traditional aluminum alloy window frame flows backwards is effectively solved, the water outlets and the drainage openings are distributed in a staggered mode, air pressure can be staggered, rainwater is prevented from flowing backwards, and the aluminum alloy window frame drainage system is suitable for being used and popularized.

Description

technical field [0001] The invention relates to the field of door and window drainage, in particular to an aluminum alloy window frame drainage system that prevents rainwater from pouring back. Background technique [0002] Existing aluminum alloy doors and windows drain the indoor water to the outside through the drain hole, but the drain hole is located above the cavity, such as attached figure 1 As shown, but when running into rainy weather or windy weather, it will cause rainwater to pour back or dust to enter the room, causing troubles to people. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides an aluminum alloy window frame drainage system with reasonable structural design and preventing rainwater backflow. [0004] The present invention is achieved through the following technical solutions: [0005] An aluminum alloy window frame drainage system for preventing rainwater from pouring back, comprising ...
