Description

Technical Field

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

[0002] The thermally-insulated aluminum alloy door and window system is a high-performance door and window product widely used in modern buildings. Its main structure is that the inner and outer sides are made of aluminum alloy material, and the middle layer is made of high-strength nylon material as a heat insulation connection. This design can effectively reduce heat conduction, improve the thermal insulation performance of doors and windows, and achieve a good heat insulation effect.

[0003] Usually, the outdoor side frame cavity of the thermally-insulated aluminum alloy door and window system is equipped with a drainage channel facing the outdoors, but due to the limitation that it cannot drain water indoors, the indoor side frame cavity and the insulation strip cavity are generally not equipped with drainage channels. In seasons with heavy rain or humid climates, rainwater or moisture tends to accumulate in the indoor side frame cavity and the insulation strip cavity after the doors and windows have been used for a period of time, and stay there for a long time. Long-term high humidity environment may affect the structural integrity of the aluminum alloy frame and reduce the safety of 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 thermal insulation aluminum alloy door and window system. Summary of the invention

[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.

[0022] The present invention will be further described below in conjunction with the embodiments and drawings.

[0023] In the embodiment, Figure 1~Figure 3 As shown, a thermally-broken aluminum alloy door and window for preventing water from accumulating 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 upper and 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 passing surface of the fourth drainage channel d within the range of the first insulation strip cavity 5. This embodiment uses multiple drainage channels to collect the accumulated water above the indoor fixed frame 1, the outdoor fixed frame 2 and the first insulation strip cavity 5 and then discharge it to the outside, preventing long-term accumulation of water from causing damage to the aluminum alloy frame, helping to reduce the corrosion risk of the aluminum alloy frame in a high humidity environment, extending the service life of doors and windows, and ensuring integrity and safety. Each drainage channel is set inside the aluminum alloy frame and the first insulation strip cavity 5, with little change to the appearance of the existing structure, which is conducive to production and on-site construction.

[0024] In the embodiment, Figure 1As shown, the top wall of the indoor fixing frame 1 is provided with a first drainage hole 8 to form a first drainage channel a; the first thermal insulation strip 3 is provided with a through second drainage hole 9 to form a second drainage channel b; the top wall of the outdoor fixing frame 2 is provided with a third drainage hole 10 to form a third drainage channel c; the side wall of the indoor fixing frame 1 is provided with a fourth drainage hole 11, and the side wall of the outdoor fixing frame 2 is provided with a fifth drainage hole 12, and 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. This embodiment uses the third thermal insulation strip 6 as the drainage surface to avoid direct contact between the indoor fixing frame 1 and the outdoor fixing frame 2, thereby ensuring the original thermal insulation performance of the first thermal insulation strip cavity 5.

[0025] In the embodiment, Figure 1 As shown, the upper surface of the third heat-insulating strip 6 is inclined, with the indoor side being higher and the outdoor side being lower. This structure utilizes gravity to better achieve drainage to the outside.

[0026] 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 the 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.
