Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a thermally-insulated aluminum alloy door and window capable of preventing water from accumulating in a heat-insulating strip cavity. Background Art

[0002] Thermally-insulated aluminum alloy door and window systems are a high-performance product widely used in modern architecture. Their primary structure is constructed of aluminum alloy on both the interior and exterior sides, with a high-strength nylon interlayer for thermal insulation. This design effectively reduces heat conduction, improves the thermal insulation performance of the doors and windows, and achieves excellent thermal insulation.

[0003] Typically, the exterior side frame cavity of thermally insulated aluminum alloy door and window systems is equipped with drainage channels facing outdoors. However, due to the limitation of not being able to drain indoors, the interior side frame cavity and insulation strip cavity are generally not equipped with drainage channels. During rainy or humid seasons, rainwater and moisture tend to accumulate in the interior side frame cavity and insulation strip cavity after the doors and windows have been used for a period of time, and remain there for a long time. Prolonged high humidity environment may affect the structural integrity of the aluminum alloy frame and reduce the safety of the doors and windows. It may also cause corrosion, mold growth, and other problems, affecting the comfort and hygiene of the indoor environment.

[0004] Based on this, it is necessary to improve the drainage design of the existing thermally-insulated aluminum alloy door and window system. Utility Model Content

[0005] In order to improve the drainage performance of thermally-insulated aluminum alloy doors and windows in actual applications and provide users with a more comfortable and efficient living environment, the utility model provides a thermally-insulated aluminum alloy door and window that prevents water accumulation in the insulation strip cavity.

[0006] The technical solution adopted by the present invention is as follows: A thermally-insulated aluminum alloy door and window for preventing water accumulation in the insulation strip cavity, comprising: an indoor fixing frame and an outdoor fixing frame, which are used to be fixed in the wall; a first insulation strip and a second insulation strip, which respectively connect the upper and lower ends of the indoor fixing frame and the outdoor fixing frame, and form a first insulation strip cavity; a third insulation strip, which is arranged between the first insulation strip and the second insulation strip, and divides the first insulation strip cavity into two upper and lower cavities; a first drainage channel, which passes through the top wall of the indoor fixing frame to the interior; a second drainage channel, which passes through the top wall of the first insulation strip to the first insulation strip cavity; a third drainage channel, which passes through the top wall of the outdoor fixing frame to the interior; a fourth drainage channel, which converges the first drainage channel, the second drainage channel and the third drainage channel to the outdoors, and the upper surface of the third insulation strip serves as the water flow surface of the fourth drainage channel within the range of the first insulation strip cavity.

[0007] Preferably, the first thermal insulation strip cavity is filled with polyurethane foam in an area below the third thermal insulation strip.

[0008] Preferably, a first drainage hole is provided on the top wall of the indoor inner fixing frame to form the first drainage channel.

[0009] Preferably, the first thermal insulation strip is provided with a through second drainage hole to form the second drainage channel.

[0010] Preferably, a third drainage hole is provided on the top wall of the outdoor fixing frame to form the third drainage channel.

[0011] Preferably, the side wall of the indoor fixing frame is provided with a fourth drainage hole, and the side wall of the outdoor fixing frame is provided with a fifth drainage hole. The fourth drainage hole, the upper surface of the third insulation strip and the fifth drainage hole together form the fourth drainage channel.

[0012] Preferably, the upper surface of the third heat-insulating strip is tilted, with the indoor side being higher and the outdoor side being lower.

[0013] Preferably, it also includes: an indoor movable frame and an outdoor movable frame, which are used to fix the glass; a fourth insulation strip and a fifth insulation strip, which respectively connect the upper and lower ends of the indoor movable frame and the outdoor movable frame and form a second insulation strip cavity; a fifth drainage channel, which passes through the outdoor movable frame from top to bottom and reaches the top wall of the outdoor fixed frame.

[0014] Preferably, the top wall and the bottom wall of the outdoor movable frame are provided with a sixth drainage hole to form the fifth drainage channel.

[0015] The utility model has the following beneficial effects:

[0016] 1. Multiple drainage channels are used to collect and drain the accumulated water above the indoor and outdoor fixing frames and the first insulation strip cavity. This prevents long-term water accumulation from damaging the aluminum alloy frame, helps reduce the risk of corrosion of the aluminum alloy frame in high humidity environments, extends the service life of doors and windows, and ensures their integrity and safety.

[0017] 2. Each drainage channel is set inside the aluminum alloy frame and the first insulation strip cavity, which makes little change to the appearance of the existing structure and is conducive to production and on-site construction;

[0018] 3.

[0025] The present invention will be further described below in conjunction with the embodiments and drawings.

[0026] In the embodiment, Figures 1 to 3 As shown, a thermally-insulated aluminum alloy door and window for preventing water accumulation in the insulation strip cavity comprises: an indoor fixing frame 1 and an outdoor fixing frame 2, which are used to be fixed in the wall; a first insulation strip 3 and a second insulation strip 4, which respectively connect the upper and lower ends of the indoor fixing frame 1 and the outdoor fixing frame 2, and form a first insulation strip cavity 5; a third insulation strip 6, which is arranged between the first insulation strip 3 and the second insulation strip 4, and divides the first insulation strip cavity 5 into two cavities, an upper and a lower cavities; a first drainage channel a, which passes through the top wall of the indoor fixing frame 1 to the interior; a second drainage channel b, which passes through the top wall of the first insulation strip 3 to the first insulation strip cavity 5; a third drainage channel c, which passes through the top wall of the outdoor fixing frame 2 to the interior; a fourth drainage channel d, which converges the first drainage channel a, the second drainage channel b and the third drainage channel c to the outdoors, and the upper surface of the third insulation strip 6 serves as the water flow surface of the fourth drainage channel d within the range of the first insulation strip cavity 5. This embodiment utilizes multiple drainage channels to collect and drain accumulated water above the indoor fixing frame 1, the outdoor fixing frame 2, and the first insulation strip cavity 5. This prevents long-term water accumulation from damaging the aluminum alloy frame, helping to reduce the risk of corrosion in high-humidity environments, extending the service life of doors and windows, and ensuring their integrity and safety. The drainage channels are located within the aluminum alloy frame and the first insulation strip cavity 5, requiring minimal changes to the existing structure, facilitating production and on-site construction.

[0027] In the embodiment, Figure 1 As shown, the top wall of the indoor fixing frame 1 is provided with a first drainage hole 8, forming a first drainage channel a; the first thermal insulation strip 3 is provided with a second drainage hole 9 extending therethrough, forming a second drainage channel b; the top wall of the outdoor fixing frame 2 is provided with a third drainage hole 10, forming a third drainage channel c; the side walls of the indoor fixing frame 1 are provided with a fourth drainage hole 11, and the side walls of the outdoor fixing frame 2 are provided with a fifth drainage hole 12. The fourth drainage hole 11, the upper surface of the third thermal insulation strip 6, and the fifth drainage hole 12 together form a fourth drainage channel d. In this embodiment, the third thermal insulation strip 6 is used as the drainage surface, avoiding direct contact between the indoor fixing frame 1 and the outdoor fixing frame 2, thereby maintaining the original thermal insulation performance of the first thermal insulation strip cavity 5.

[0028] In the embodiment, Figure 1 As shown, the upper surface of the third heat-insulating strip 6 is tilted, with the indoor side higher and the outdoor side lower. This structure utilizes gravity to better achieve outward drainage.

[0029] In the embodiment, Figure 1 As shown, the area of ​​the first insulation strip cavity 5 below the third insulation strip 6 is filled with polyurethane foam 7. Filling with polyurethane foam 7 can prevent moisture from being retained in the first insulation strip cavity 5, ensuring that the first insulation strip cavity 5 achieves a water-free environment.

[0030] In the embodiment, Figure 2 、 Figure 3 The figure shows a thermally insulated aluminum alloy window. In addition to the fixed frame, it also includes: an indoor movable frame 13 and an outdoor movable frame 14 for fixing the glass 15; a fourth insulation strip 16 and a fifth insulation strip 17, which connect the upper and lower ends of the indoor movable frame 13 and the outdoor movable frame 14, respectively, and form a second insulation strip cavity 18; and a fifth drainage channel e, which extends vertically through the outdoor movable frame 14 to the top wall of the outdoor fixed frame 2. Sixth drainage holes 19 are provided on the top and bottom walls of the outdoor fixed frame 2, forming the fifth drainage channel e. This structure allows the fourth drainage channel d to not only drain accumulated water inside and outside the fixed frame, but also drain rainwater outward from the fourth drainage channel d when the window is slightly opened on rainy days.

[0031] Obviously, the above embodiments of the present invention are merely examples for illustrating the present invention and are not intended to limit the implementation of the present invention. Other obvious changes or modifications derived from the essence of the present invention still fall within the scope of protection of the present invention.
