Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and in particular to a steel-aluminum structure skylight with a pressure balance chamber. Background Art

[0002] Currently, the steel-aluminum composite structure opening skylights on the domestic market in China have only one sealing strip between the aluminum alloy window sash and the steel window seat.

[0003] When the outdoor air pressure of the skylight is higher than the indoor air pressure, the air on the side with higher outdoor pressure will carry heat, rain, and dust, easily penetrate the only sealing strip, and enter the indoor side with lower pressure. As a result, the air tightness, water tightness, wind pressure resistance, thermal insulation, and sound insulation performance of the entire skylight are greatly attenuated, and cannot meet the corresponding grade indicators required by the national standard. Utility Model Content

[0004] In order to solve the above-mentioned problems existing in the prior art, the utility model provides a steel-aluminum structure skylight with a pressure balance chamber, which reduces the penetration speed and amount of air from the side with higher outdoor pressure to the side with lower indoor pressure, thereby significantly improving the air tightness, water tightness, wind resistance, heat insulation and sound insulation performance of the entire window.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A steel-aluminum structure skylight with a pressure balance chamber, comprising a window sash and a window seat, one side of the window sash is rotatably connected to one side of the window seat, a window opener is rotatably arranged below the window seat, the other end of the window opener is rotatably connected to the window sash, and the window opener is located in the middle of the window seat;

[0007] A first sealing strip is fixedly arranged on the window sash, the first sealing strip is located at the inner edge of the window sash, the first sealing strip is in contact with the outer side of the window seat, and the first sealing strip is an O-shaped structure;

[0008] A second sealing strip is fixedly arranged on the window seat, the second sealing strip is located at the upper end of the window seat, the second sealing strip is in contact with the inner lower end of the window sash, and the second sealing strip is an O-shaped structure.

[0009] Furthermore, the first sealing strip is continuously arranged along and penetrates the four sides of the window sash, and the second sealing strip is continuously arranged along and penetrates the four sides of the window seat.

[0010] Furthermore, the first sealing strip and the second sealing strip together with the window sash and the window seat form a self-enclosed pressure balance chamber structure.

[0011] Furthermore, the window sash and the window seat are connected via a hinge.

[0012] The beneficial effects of the utility model are:

[0013] By setting the first sealing strip and the second sealing strip, the technical effect that can be achieved is that the first sealing strip and the second sealing strip, together with the window sash and the window seat, form a self-enclosed cavity structure, namely, a pressure balance chamber. The cavity forms an isolation layer between indoor air and outdoor air. When the outdoor air pressure is high and penetrates the first sealing strip into the pressure balance chamber, due to the blocking effect of the second sealing strip, the outdoor air entering the pressure balance chamber can no longer penetrate the second sealing strip at the same penetration speed and penetration amount. Therefore, the air pressure in the pressure balance chamber will gradually increase due to the continuous entry of outdoor air, and finally the air pressure in the pressure balance chamber will rise to the same pressure value as the outdoor air pressure.

[0014] As a result, the pressure of the outdoor air on both sides of the first sealing strip and the pressure balance chamber is balanced, so that the outdoor air pressure can no longer penetrate the first sealing strip into the pressure balance chamber, which greatly reduces the amount of outdoor air that continuously penetrates the two sealing strips and continuously penetrates into the room, and greatly reduces the mutual flow and penetration between indoor and outdoor air; conversely, when the indoor air pressure is higher than the outdoor air pressure, the pressure balance chamber can also greatly reduce the amount of indoor air pressure that continuously penetrates the two sealing strips and continuously leaks to the outside, thereby significantly improving the air tightness, water tightness, wind resistance, heat insulation and sound insulation performance of the entire window.

[0026] Reference Figures 1 to 5 , a steel-aluminum structure skylight with a pressure balance chamber disclosed by the utility model, includes a window sash 2 and a window seat 3, one side of the window sash 2 is rotatably connected to one side of the window seat 3, the window sash 2 and the window seat 3 are connected by a hinge 6, the window sash 2 is aluminum alloy, and the window seat 3 is a steel component.

[0027] A window opener 1 is rotatably provided below the window seat 3, and the window opener 1 is located in the middle of the window seat 3. The other end of the window opener 1 is rotatably connected to the window sash 2 through a pin.

[0028] A first sealing strip 4 is fixedly provided on the window sash 2. The first sealing strip 4 is located at the inner edge of the window sash 2. The first sealing strip 4 contacts the outer side of the window seat 3. The first sealing strip 4 is an O-shaped structure.

[0029] A second sealing strip 5 is fixedly provided on the window seat 3 . The second sealing strip 5 is located at the upper end of the window seat 3 . The second sealing strip 5 is in contact with the inner lower end of the window sash 2 . The second sealing strip 5 is an O-shaped structure.

[0030] The first sealing strip 4 is continuously arranged along the four sides of the window sash 2 and penetrates therethrough, and the second sealing strip 5 is continuously arranged along the four sides of the window seat 3 and penetrates therethrough.

[0031] The first sealing strip 4 and the second sealing strip 5 together with the window sash 2 and the window seat 3 form a self-enclosed pressure balance chamber structure.

[0032] The first sealing strip 4 and the second sealing strip 5, together with the window sash 2 and the window seat 3, constitute a self-enclosed pressure balance chamber structure. The cavity forms an isolation layer between the indoor air and the outdoor air. When the outdoor air pressure is high and penetrates the first sealing strip 4 to enter the pressure balance chamber, due to the blocking effect of the second sealing strip 5, the outdoor air entering the pressure balance chamber can no longer penetrate the second sealing strip 5 at the same penetration speed and penetration amount. Therefore, the air pressure in the pressure balance chamber will gradually increase due to the continuous entry of outdoor air, and finally the air pressure in the pressure balance chamber will rise to the same pressure value as the outdoor air pressure.

[0033] Therefore, the outdoor air pressure on both sides of the first sealing strip 4 is balanced with the air pressure in the pressure balance chamber, so that the outdoor air pressure can no longer penetrate the first sealing strip 4 to enter the pressure balance chamber, which greatly reduces the amount of outdoor air pressure that continuously penetrates the two sealing strips and continuously penetrates into the room, greatly reducing the mutual flow and penetration between indoor and outdoor air.

[0034] On the contrary, when the indoor air pressure is higher than the outdoor air pressure, the pressure balance chamber can also greatly reduce the amount of outdoor air pressure that continuously penetrates the two sealing strips and continuously penetrates into the room, thereby significantly improving the air tightness, water tightness, wind resistance, heat insulation and sound insulation performance of the entire window.

[0035] The working principle and use process of the utility model: the first sealing strip 4 and the second sealing strip 5, together with the window sash 2 and the window seat 3, form a self-enclosed space, forming a pressure balance chamber with isolation effect between the outdoor pressure and the indoor pressure.

[0036] When the air on the side with higher outdoor air pressure penetrates the first sealing strip 4 and enters the pressure balance chamber, the pressure value will be reduced to a certain extent.

[0037] When the air in the pressure balance chamber tries to penetrate the second sealing strip 5 again, the difference between the air pressure value and the air pressure value on the indoor side of the window sash 2 and the window seat 3 will be reduced, so that the penetration speed and penetration amount of the air in the pressure balance chamber when penetrating the second sealing strip 5 will be significantly reduced.

[0038] When there is a difference in the penetration amount and penetration speed of the air in the pressure balance chamber at the first sealing strip 4 and the second sealing strip 5, the air pressure value in the pressure balance chamber will gradually increase until the air pressure in the pressure balance chamber is equal to the outdoor air pressure.

[0039] When the outdoor air pressure on both sides of the first sealing strip 4 reaches a balance with the air pressure in the pressure balance chamber, the outdoor air pressure can no longer penetrate the first sealing strip 4 to enter the pressure balance chamber, which greatly reduces the amount of outdoor air pressure that continuously penetrates the two sealing strips and continuously penetrates into the room, greatly reducing the mutual flow and penetration between indoor and outdoor air.

[0040] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
