Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy doors and windows, and in particular to an aluminum alloy outward-opening window screen integrated window drainage structure. Background Art

[0002] Integrated screen windows are architectural windows that share a frame with the screen and door sash. They offer advantages such as good indoor ventilation and lighting, thermal insulation and energy savings, mosquito protection, excellent safety and security, and a compact and aesthetically pleasing structure, making them the most widely used type of window in the home decoration market. These integrated screen windows feature hinged, outward-opening glass windows that directly face the outdoors. If the outward-opening window's waterproofing and drainage structure is not properly designed, rainwater can backflow into the room when exposed to harsh external wind pressure.

[0003] Existing outward-opening window sash frames are equipped with sealing strips to prevent rainwater from seeping through the gap between the sash and the frame. A drain is provided at the bottom of the track groove below the window frame, allowing rainwater to drain out through this outlet. However, when subjected to high wind pressure, the rubber sealing strips lack sufficient sealing strength to withstand the pressure of the air, allowing rainwater to pass through the gaps, enter the door and window cavity, and even flow back into the room. Furthermore, the glue between the glass and the window frame loses its elasticity over time, creating gaps that allow rainwater to easily seep into the window frame profile cavity and into the room. Summary of the Invention

[0004] In response to the above problems, the utility model provides an aluminum alloy outward-opening window screen integrated window drainage structure, in which openings or through holes are provided on the outer window frame profile, the auxiliary frame profile, the outward-opening window sash profile and the outdoor rubber strip, so that the cavities of each profile close to the outdoors are connected to the outdoor ambient atmosphere, so that there is no pressure difference between the profile cavity and the sealed cavity between the profiles and the outdoors, and rainwater in the cavity can flow out smoothly to the outside, thereby improving the drainage capacity of the window screen integrated window.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An aluminum alloy outward-opening window screen integrated window drainage structure, wherein the outer window frame profile is installed on the building window opening, at the position corresponding to the inward-opening window: the outer window frame profile is connected to the auxiliary frame profile, the edge of the auxiliary frame profile is abutted and sealed against the edge of one side of the outward-opening window sash profile, and the other side of the outward-opening window sash profile is fixed to the outward-opening window glass by an outdoor adhesive strip;

[0007] The outdoor rubber strip is provided with left and right side opening sections, the left and right side walls of the inner cavity of the outward-opening window sash profile are respectively provided with window sash water inlet holes and window sash drainage holes, the inner cavity side walls of the attached frame profile are respectively provided with attached frame water inlet holes and attached frame drainage holes, and the outer window frame profile is provided with an outer window frame drainage hole against the outer wall.

[0008] The opening section of the outdoor rubber strip is preferably at the vertical upper portion of the frame shape, so as to achieve the effect of storing a certain amount of rainwater in the first sealed cavity.

[0009] The water inlet and drainage holes of the window sash are located near the two ends of the profile and the position where the hinge is installed, so as to achieve the effect of draining rainwater in the cavity.

[0010] The drainage hole of the outer window frame is located at the bottom of the outer window frame profile.

[0011] The flow path of rainwater is: the opening of the outdoor rubber strip---the first sealed cavity (the sealed cavity formed by the outward-opening window sash profile, the inner window frame profile, and the thermally broken aluminum)---the outward-opening window sash profile cavity---the second sealed cavity (the sealed cavity formed by the outward-opening window sash profile, the attached frame profile, the thermally broken aluminum, and the middle rubber strip)---the attached frame profile cavity---the third sealed cavity (the sealed cavity formed by the attached frame profile and the outer window frame profile)---the external environment; thus, the external air pressure and rainwater can both circulate through this path, forming an isobaric cavity inside the window to prevent rainwater from seeping in and being unable to be discharged due to pressure difference.

[0012] The water inlet hole and the drainage hole of the auxiliary frame are staggered, so that the air flow and water passages form more bends, reducing the risk of drainage backflow.

[0013] A one-way drain valve is provided at the drain hole of the outer window frame. The one-way drain valve comprises a valve plate hinged at its upper end to the drain hole of the outer window frame. This valve allows water to flow only from indoors to outdoors. When the outdoor wind pressure is less than or equal to the indoor wind pressure, the valve plate is flushed open by the rainwater in the cavity, allowing rainwater to drain outdoors normally. When the outdoor wind pressure is greater than the indoor wind pressure, the valve plate is forced closed by the wind pressure, closing the one-way valve and preventing rainwater from flowing back into the room.

[0014] Advantages of utility models

[0015] 1. The utility model forms multiple isobaric cavities by establishing a passage between the outer profile of the aluminum alloy outward-opening window with integrated screen and the sealed cavity, so as to achieve equal pressure between the cavity and the external air pressure, thereby preventing the phenomenon that rainwater that penetrates into the sealed cavity cannot be discharged, thereby improving the drainage capacity of the window with integrated screen, and preventing rainwater from flowing back into the room.

[0016] 2. The structure of the utility model can be expanded to other types of doors and windows, or sealed structures that are in contact with the outdoor environment, and the scope of expansion is wide. BRIEF DESCRIPTION OF THE DRAWINGS
