Description

Technical Field

[0001] The present application relates to the field of thermally-broken aluminum doors and windows, and in particular to a thermally-broken aluminum window frame with a drainage structure. Background Art

[0002] Aluminum alloy windows are windows with frames and sash structures made of aluminum alloy building profiles. They are divided into ordinary aluminum alloy doors and windows and broken bridge aluminum alloy doors and windows. Aluminum alloy windows are beautiful, sealed, and have high strength. They are widely used in the field of construction engineering. In home decoration, aluminum alloy doors and windows are often used to enclose balconies.

[0003] Because the surface of aluminum alloy is oxidized and shiny. The window frame is large, and a large area of ​​glass can be inlaid, allowing sufficient and bright light in the room, enhancing the virtual and real contrast between the indoor and outdoor facades, and making the room more layered. Therefore, many owners choose to use aluminum alloy doors and windows in decoration. The thermal insulation aluminum is made of two aluminum alloy profiles connected by a heat insulation strip to form a hollow structure, which isolates the indoor and outdoor. The heat insulation strip in the middle plays the role of heat insulation and sound insulation. In order to increase the thermal insulation effect of thermal insulation aluminum doors and windows, some doors and windows are designed with heat insulation strips to form a multi-channel sealing structure to improve the thermal insulation effect.

[0004] With regard to the above-mentioned related technologies, when it rains, if the owner fails to close the window in time, rainwater will enter the room under the action of wind, and rainwater will accumulate between the multiple insulation strips of the window frame. Due to the water-blocking effect of the insulation strips, rainwater accumulates in the window frame. At this time, it needs to be wiped away manually, which increases the difficulty of cleaning, especially when the window is located at a high position, the cleaning process of the accumulated water between the multiple insulation strips is more difficult.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0033] The present application embodiment discloses a thermally insulated aluminum window frame with a drainage structure. Figure 1 A thermally-insulated aluminum window frame with a drainage structure includes a window frame body 1. The window frame body 1 includes aluminum profiles 11 located on both sides, and a first sealing strip 12 and a second sealing strip 13 are commonly connected between the two aluminum profiles 11. The two aluminum profiles 11, the first sealing strip 12 and the second sealing strip 13 jointly form an isobaric cavity 14. An isobaric rubber strip 2 is installed outside the isobaric cavity 14. The isobaric rubber strip 2 is composed of a supporting portion 21 and an abutting portion 22. The abutting portion 22 is located on the side of the supporting portion 21 away from the isobaric cavity 14. The abutting portion 22 includes three raised insulation strips 221 arranged along the thickness direction of the window frame body 1, and the three insulation strips 221 are evenly arranged along the thickness direction of the window frame body 1. When the window frame and the window sash are closed, the three insulation strips 221 can abut against the window sash, so that the pressure inside and outside the window frame body 1 is balanced, reducing the possibility of rainwater infiltrating into the room through the gap.

[0034] Reference Figure 1, a plurality of first drainage holes 3 are provided between adjacent heat insulation strips 221 at the bottom edge of the window frame body 1, and the plurality of first drainage holes 3 are arranged along the length direction of the bottom edge of the window frame body 1, and the support portion 21 correspondingly provides a plurality of second drainage holes 4. The aluminum profile 11 near the indoor side forms an inner drainage cavity 5, and the side wall near the indoor side is provided with an inner drainage port. Similarly, the aluminum profile 11 near the outdoor side also forms an outer drainage cavity 51, and the side wall near the outdoor side is provided with a plurality of outer drainage ports, and the plurality of outer drainage ports are evenly arranged along the length direction of the bottom edge of the window frame body 1. The first drainage hole 3 near the indoor side, the second drainage hole 4 on the same side are connected with the inner drainage port to form an inner drainage channel, which is responsible for draining rainwater that penetrates into the window frame to the indoor side. At the same time, the first drainage hole 3 near the outdoor side, the second drainage hole 4 on the same side and the plurality of outer drainage ports are connected to form an outer drainage channel to drain rainwater to the outdoor side.

[0035] The design of the drainage channel allows the accumulated water between the insulation strips 221 to quickly flow into the corresponding inner drainage cavity 5 or outer drainage cavity 51 along the first drainage hole 3 and the second drainage hole 4 when the window is forgotten to be closed or the window sash is not tightly closed on rainy days. Subsequently, the rainwater will be discharged from the window frame through the inner drainage port or several outer drainage ports, thereby avoiding the problem of rainwater accumulation inside the window frame. This design not only simplifies the cleaning process, but also prolongs the service life of the window frame and improves the user's living experience.

[0036] Reference Figure 1 The support portion 21 is provided with a plurality of heat preservation chambers along the width direction of the window frame body 1. A partition layer 211 is fixedly connected to the heat preservation chamber connected to the second drainage hole 4. The partition layer 211 divides the heat preservation chamber into a diversion chamber 212 and a sealing chamber 213. The second drainage hole 4 is connected to the diversion chamber 212. By providing the partition layer 211, the heat preservation chamber can achieve the heat preservation effect while draining the accumulated water through the diversion chamber 212, so that the rainwater can also achieve the heat preservation performance during the drainage process. At the same time, the smooth flow of the diversion chamber 212 also ensures the smooth discharge of rainwater, improving the overall use effect of the window frame body 1. At the same time, the design of the heat preservation chamber is combined with the double-channel design so that there is at least one complete heat preservation chamber between the two channels. When the window sash and the window frame are closed, the inner and outer sealed chambers are realized, further ensuring the realization of the heat preservation effect.

[0037] Further, see Figure 1, the dividing layer 211 located in the inner drainage channel is inclined toward the indoor direction from the side away from the isobaric cavity 14 to the side close to the isobaric cavity 14, while the dividing layer 211 located in the outer drainage channel is inclined toward the outdoor direction. The bottom walls of the inner drainage cavity 5 and the outer drainage cavity 51 are inclined in the direction away from each other from the side away from the isobaric cavity 14 to the side close to the isobaric cavity 14. This inclined design makes full use of the effect of gravity, so that rainwater can flow more smoothly to the drain outlet when passing through the diversion cavity 212, thereby improving the drainage efficiency, reducing the retention time of rainwater in the drainage process, and reducing the risk of moisture inside the window frame. At the same time, the bottom wall of the inner drainage cavity 5 is inclined downward from the two ends along the length direction to the position close to the inner drainage outlet. This inclined setting can ensure that the accumulated water in the inner drainage cavity 5 can be completely discharged, avoiding the residual accumulated water.

[0038] Further, see Figure 1 The inner drainage hole is connected to a collection box 6 through a drainage pipe. The collection box 6 is placed on the inner side of the window frame body 1. The collection box 6 can be sealed and connected to the inner drainage cavity 5 through a water pipe. By providing the collection box 6, the accumulated water discharged from the inner drainage hole can be conveniently collected, avoiding the inconvenience caused by the accumulated water being directly discharged into the room. At the same time, the sealed connection between the collection box 6 and the inner drainage cavity 5 can ensure the sealing of the inner drainage cavity 5 when the window sash and the window frame are tightly closed, further improving the insulation effect. The cleaning staff can separate the collection box 6 from the water pipe, which is convenient for the cleaning staff to clean the accumulated water in the collection box 6.

[0039] All external drain outlets are open downwards, and this arrangement ensures that the accumulated water discharged from the external drain outlets can flow directly to the outdoors, avoiding the accumulation of water on the window frame body 1, and preventing strong winds and rainwater from flowing back. At the same time, it is not easy to be blown directly by the wind and produce wind whistling sounds.

[0040] Reference Figure 2A sealing assembly 7 is provided at all positions of the external drain outlets of the aluminum profile 11. The sealing assembly 7 includes a sliding plate 71 with a plurality of vents 711, and each vent 711 corresponds to an external drain outlet. The aluminum profile 11 is fixedly connected to a slide rail 72. The sliding plate 71 can slide along the length direction of the bottom edge of the window frame in the sliding rail to open and seal the external drain outlet. An expansion block 73 is fixedly connected to one end of the sliding plate 71. One end of the expansion block 73 is fixedly connected to the aluminum profile 11, and the other end is fixedly connected to the sliding plate 71. The expansion block 73 is connected to one of the external drain outlets to ensure that the expansion block 73 can respond in time when there is water accumulation. The expansion block 73 expands when absorbing water, thereby pushing the sliding plate 71 to slide. At this time, the vent 711 is connected to the external drain outlet to open the external drain outlet. The expansion block 73 shrinks when dehydrated, thereby driving the sliding plate 71 to slide. The vent 711 is not connected to the external drain outlet, thereby sealing the external drain outlet. The design of the sealing component 7 not only realizes the automatic opening and closing function of the external drain outlet, but also responds to the humidity of the external environment through the water absorption and expansion characteristics of the expansion block 73. On rainy days or in high humidity environments, the sealing component 7 will automatically open the external drain outlet to ensure that rainwater inside the window frame can be discharged in time. On sunny days or in low humidity environments, the sealing component 7 will automatically close the external drain outlet to maintain the sealing and thermal insulation effect of the window frame.

[0041] The implementation principle of the thermally-broken aluminum window frame with a drainage structure in the embodiment of the present application is as follows: when the window is forgotten to be closed or the window frame is not closed tightly on a rainy day, after the rainwater enters between the multiple heat-insulating strips 221 at the bottom edge of the window frame body 1, the rainwater will enter the diversion cavity 212 from the first drainage hole 3 and enter the inner drainage cavity 5 or the outer drainage cavity 51 from the second drainage hole 4 along the partition layer 211. The rainwater in the inner drainage cavity 5 will enter the collection box along the water pipe, and the rainwater in the outer drainage cavity 51 will cause the expansion block 73 to absorb water and expand, so that the vent 711 is connected with the outer drainage port, and the rainwater will flow out from the outer drainage port, reducing the water accumulation between the heat-insulating strips 221, simplifying the cleaning process, extending the service life of the window frame, and improving the user's living experience. When it is not raining, the expansion block 73 dehydrates and shrinks, thereby closing the external drainage outlet and sealing the external drainage cavity 51; when the window sash and the window frame are tightly closed, the sealing of the internal drainage cavity 5 is achieved, and at the same time, the isobaric rubber strip 2 abuts against the window sash to achieve the insulation effect of the doors and windows.

[0042] The embodiment of the present application has the effect of making it easier to clean the accumulated water between the multiple insulation strips 221.

[0043] 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.
