[0004] For example, a Chinese patent discloses an aluminum alloy inner flat energy-saving door and window, and the patent publication number is CN204402250U. The door and window include an aluminum frame, an aluminum pressure line, a sash material, and a hollow glass installed between the aluminum pressure line and the sash material. The aluminum pressure line and the sash material are connected by an I-type insulation strip and a T-type insulation strip. Two I-type insulation strips are arranged in the aluminum frame. Sealant is arranged between the outer side of the hollow glass and the sash material, and between the inner side of the hollow glass and the aluminum pressure line. A waterproof sealing strip is arranged above the I-type insulation strip in the middle of the aluminum frame. Sealing strips are arranged at the connection between the aluminum frame, the aluminum pressure line, and the sash material. After the door and window are closed, the sealing strip on the aluminum frame is tightly sealed against the sash material, the sealing strip on the aluminum pressure line is tightly sealed against the aluminum frame, and the waterproof sealing strip in the middle of the aluminum frame is tightly sealed between the T-type insulation strip and the profile of the aluminum pressure line, thereby realizing triple sealing of the door and window and achieving energy saving.

At least two I-type heat insulation strips 2 6 are installed and fixed in the aluminum frame 4, and at least two I-type heat insulation strips 1 5 are installed and fixed between the sash material 2 and the aluminum pressure line 3. For the I-type heat insulation strips 1 5 and the I-type heat insulation strips 2 6, in this embodiment, the number is two as an example. The two I-type heat insulation strips 1 5 between the sash material 2 and the aluminum pressure line 3 are one on the top and the other on the bottom, and the two I-type heat insulation strips 2 6 in the aluminum frame 4 are one on the top and the other on the bottom. Sealant is provided between the outdoor side of the insulating glass 1 and the sash material 2, and between the indoor side of the insulating glass 1 and the aluminum pressure line 3, so as to ensure the high sealing performance of the insulating glass 1 installed in the door and window.
[0030] Reference Figure 1 and Figure 2, between the fan material 2 and the aluminum frame 4 and between the aluminum pressure wire 3 and the aluminum frame 4, the fan material 2 is on the outdoor side of the door and window, and the aluminum pressure wire 3 is on the indoor side of the door and window. First, a rubber strip installation groove 1 41 and a rubber strip installation groove 2 42 are respectively arranged on the outdoor side of the aluminum frame 4. The rubber strip installation groove 1 41 faces the indoor side of the door and window, and the rubber strip installation groove 2 42 faces the fan material 2 upward. A sealing rubber strip 1 7 is installed in the rubber strip installation groove 1 41, and a sealing rubber strip 2 8 is installed in the rubber strip installation groove 2 42. An avoidance space 21 with a right-angled cross-section for avoiding the rubber strip installation groove 1 41 and the rubber strip installation groove 2 42 is opened on the outdoor side of the fan material 2. The avoidance space 21 faces the The surface on the outdoor side (that is, facing the sealing strip 17) is set as wall surface 1 211, and the surface of the avoidance space 21 facing the aluminum frame 4 (that is, facing the sealing strip 28) is set as wall surface 212. After the doors and windows are closed, the sealing strip 17 and the wall surface 1 211 are pressed against each other, and the sealing strip 28 and the wall surface 212 are pressed against each other. Among them, the sealing strip 28 is set on the outdoor side of the sealing strip 17, which can seal the space above the sealing strip 17 and the fan material 2 where rainwater easily accumulates, so that rainwater cannot gather in this space and penetrate downward into the door and window profiles, thereby improving the sealing effect of the doors and windows, making the doors and windows more energy-efficient.
[0031] It should be emphasized here that the sealing strip 8 is divided into a main body 81 and an extension 82. The main body 81 and the extension 82 are an integrated structure.

The extension 82 extends out of the strip installation groove 42 and presses against the wall 212 to achieve a sealing effect. There is also a buffer cavity between the extension 82 and the main body 81. The buffer cavity faces the outdoor side and penetrates the sealing strip 8 to form an open structure. That is, the extension 82 is only connected to the main body 81 at one end close to the indoor side. In this way, the extension 82 has greater buffering elasticity. After the doors and windows are closed, the extension 82 and the wall 212 press against each other, and the buffer cavity is gradually compacted, so that the sealing effect is better. What's more, a shielding portion 83 is provided at the end of the extension portion 82 facing the outdoor side. The shielding portion 83 and the extension portion 82 are an integrated structure. The shielding portion 83 is actually located outside the doors and windows. When the doors and windows are closed, the shielding portion 83 is tightly pressed against the outdoor outer surface of the fan material 2 and the outdoor outer surface of the aluminum frame 4, so that the shielding portion 83 can completely isolate rainwater from entering the avoidance space 21, thereby improving the sealing effect of the doors and windows.
[0032] Reference Figure 1 Secondly, a rubber strip installation groove 31 is provided on the indoor side of the aluminum pressure line 3, and the rubber strip installation groove 31 faces the inside of the door and window to the outdoor side, and a sealing rubber strip 3 9 is installed in the rubber strip installation groove 31. After the door and window are closed, the sealing rubber strip 3 9 and the aluminum frame 4 are pressed against each other. Based on the aforementioned sealing rubber strip 1 7 and sealing rubber strip 2 8, the sealing rubber strip 3 9 strengthens the sealing effect of the doors and windows.

After the sealing rubber strip 4 10 extends out of the rubber strip installation groove 43, it gradually branches into a main sealing part 11 and an auxiliary sealing part 12. The main sealing part 11 is close to the indoor side, and the auxiliary sealing part 12 is close to the outdoor side. However, there is a distance between the main sealing part 11 and the auxiliary sealing part 12 and the fan material 2. Therefore, during the opening and closing process of the door and window, the fan material 2 will not frequently collide with the main sealing part 11 and the auxiliary sealing part 12, thereby avoiding the main sealing part 11 and the auxiliary sealing part 12 from being worn and failed. An auxiliary protrusion 51 is provided on the I-type thermal insulation strip 5 located below between the fan material 2 and the aluminum pressure line 3. The auxiliary protrusion 51 and the I-type thermal insulation strip 5 are an integrated structure. It should be noted here that the auxiliary protrusion 51 is located on the side of the auxiliary sealing part 12 facing the indoor side, and the aluminum pressure line 3 is located on the side of the main sealing part 11 facing the indoor side. Therefore, after the door and window are closed, the aluminum pressure line 3 and the main sealing part 11 are pressed against each other, and the auxiliary protrusion 51 and the auxiliary sealing part 12 are pressed against each other, and the auxiliary sealing part 12 does not contact the I-type thermal insulation strip 5, thereby achieving the purpose of sealing inside the door and window, and will not cause damage to the sealing strip 410 (that is, the main sealing part 11 and the auxiliary sealing part 12).

The drainage hole 13 and the drainage hole 2 14 are arranged in sequence from the indoor side to the outdoor side. Therefore, even if rainwater penetrates into the door and window profile through the sealing strip 1 7 and the sealing strip 2 8, it will be quickly discharged from the drainage hole 13 and the drainage hole 2 14, thereby preventing the rainwater from continuing to penetrate into the sealing strip 4 10 and the sealing strip 3 9.
[0035] The implementation principle of an inward-opening energy-saving door and window in the embodiment of the present application is as follows: after the door and window are closed, the sealing strip 1 7 and the sealing strip 2 8 on the aluminum frame 4 are respectively tightly sealed with the wall 1 211 and the wall 2 212 in the avoidance space 21 on the fan material 2, the sealing strip 3 9 on the aluminum pressure line 3 is tightly sealed with the aluminum frame 4, and the sealing strip 4 10 in the aluminum frame 4 is tightly sealed with the aluminum pressure line 3, thereby realizing the quadruple sealing of the door and window, wherein the sealing strip 2 8 is located on the outdoor side of the sealing strip 1 7, and the sealing strip 2 8 is tightly sealed with the wall 2 212, which can block the easily accumulated rainwater between the upper part of the sealing strip 1 7 and the fan material 2. The space is blocked and sealed, so that rainwater cannot gather in this space and penetrate downward into the door and window profiles, thereby improving the sealing effect of doors and windows and making them more energy-efficient. In addition, a sealing strip four 10 is arranged on the side of the aluminum pressure line 3 facing the outdoor side, and the sealing strip four 10 is spaced apart from the fan material 2. In this way, the sealing strip four 10 can be pressed against the aluminum pressure line 3 to achieve sealing, while the sealing strip four 10 will not contact the fan material 2, and will not frequently collide and rub with the I-type insulation strip 5 between the fan material 2 and the aluminum pressure line 3. In this way, the service life of the sealing strip four 10 can be extended and the sealing effect of doors and windows can be improved.
[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
