Description

Technical Field

[0001] The invention relates to the technical field of doors and windows, and in particular to a drainage system in a cavity of a thermal insulation strip of a thermally-insulated aluminum alloy door and window. 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

[0005] In order to improve the drainage performance of thermally-insulated aluminum alloy doors and windows in practical applications and provide users with a more comfortable and efficient living environment, the present invention provides a drainage system in the cavity of thermal insulation strips of thermally-insulated aluminum alloy doors and windows.

[0024] The present invention will be further described below in conjunction with the embodiments and drawings.

[0025] In the embodiment, Figure 1~Figure 3As shown, the fixed frame part of a thermally-insulated aluminum alloy window comprises: an indoor fixing frame 1 and an outdoor fixing frame 2, which are used to be fixed in a wall; a first thermal insulation strip 3 and a second thermal 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 thermal insulation strip cavity 5; a first drainage channel a, which passes through the top wall of the indoor fixing frame 1 to the inside; a second drainage channel b, which passes through the top wall of the first thermal insulation strip 3 to the first thermal insulation strip cavity 5; a third drainage channel c, which passes through the top wall of the outdoor fixing frame 2 to the inside; and 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 outside, and the fourth drainage channel d adopts a non-contact connection form within the range of the first thermal 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. Moreover, each drainage channel is set inside the aluminum alloy frame and the first insulation strip cavity 5, which makes little change to the appearance of the existing structure, which is conducive to production and on-site construction.

[0026] In the embodiment, Figure 1 As shown, the top wall of the indoor fixing frame 1 is provided with a first drainage hole 6 to form a first drainage channel a; the first insulation strip 3 is provided with a second drainage hole 7 to form a second drainage channel b; the top wall of the outdoor fixing frame 2 is provided with a third drainage hole 8 to form a third drainage channel c; the indoor fixing frame 1 and the outdoor fixing frame 2 respectively have a first cantilever 9 and a second cantilever 10 extending into the first insulation strip cavity 5 as a whole, the first cantilever 9 and the second cantilever 10 have an overlapping portion, and the first cantilever 9 at the overlapping portion is located above the second cantilever 10; 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; the fourth drainage hole 11, the first cantilever 9, the second cantilever 10 and the fifth drainage hole 12 together form a fourth drainage channel d. In this embodiment, the first cantilever 9 and the second cantilever 10, which are arranged in a staggered manner, are used to achieve the connection of the drainage channel, avoiding direct contact between the indoor fixing frame 1 and the outdoor fixing frame 2, thereby ensuring the original insulation performance of the first insulation strip cavity 5.

[0027] In the embodiment, Figure 1 As shown, the end of the first cantilever 9 has a first curved portion 13 that curves downward, and the beginning of the second cantilever 10 has a second curved portion 14 that curves upward. The first curved portion 13 serves to guide water downward, and the second curved portion 14 prevents water from flowing back into the first insulation strip cavity 5. The first curved portion 13 and the second curved portion 14 enable the first cantilever 9 and the second cantilever 10 to form a more reasonable non-contact drainage channel.

[0028] In the embodiment, Figure 1 As shown, the first cantilever 9 and the second cantilever 10 are arranged obliquely, with the indoor side being higher and the outdoor side being lower. This structure utilizes gravity to better realize outward drainage.

[0029] In the embodiment, Figure 2 , Figure 3 As shown, a thermally-broken aluminum alloy window includes, in addition to the fixed frame part, an indoor movable frame 15 and an outdoor movable frame 16 for fixing glass 17; a third heat-insulating strip 18 and a fourth heat-insulating strip 19, which respectively connect the upper and lower ends of the indoor movable frame 15 and the outdoor movable frame 16, and form a second heat-insulating strip cavity 20; a fifth drainage channel e, which passes through the outdoor movable frame 16 from top to bottom to the top wall of the outdoor fixed frame 2. The top wall and the bottom wall of the outdoor fixed frame 2 are provided with a sixth drainage hole 21, forming the fifth drainage channel e. With this structure, the fourth drainage channel d can not only drain the accumulated water inside and outside the fixed frame part, but also drain rainwater from the fourth drainage channel d when the window is slightly opened on rainy days.

[0030] In the second embodiment, if Figure 4 As shown, a fixed frame portion of a thermally-insulated aluminum alloy window is provided. Compared with the first embodiment, a partial area within the first thermal insulation strip cavity 5, mainly the area below the second cantilever 10, is filled with polyurethane foam 25 to prevent moisture from being retained in the first thermal insulation strip cavity 5.

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