Description

Technical Field

[0001] The present application relates to the technical field of doors and windows for buildings, and more specifically to a hidden airway strong exhaust drainage sealed casement window structure. Background Art

[0002] Casement windows are a common window structure in many residential buildings, also known as ordinary windows or opening windows. This type of window has a simple structure and is easy to operate, but it also has some problems. First, the sealing performance of casement windows is relatively poor. In order to improve the sealing effect, it is usually necessary to use a variety of sealing strips, which increases the manufacturing cost and installation difficulty of the window. Secondly, due to poor sealing performance, casement windows are prone to condensation and leakage problems. In order to solve these problems, some casement window frames are designed with hidden drainage structures to drain condensation and leakage in the frame. However, this drainage structure is usually passive and relies only on gravity to drain water. The drainage efficiency is relatively low. Under severe weather conditions, such as strong winds and rainstorms, this drainage structure may not be able to drain the rapidly accumulated water in time, thereby affecting the service life of the window and the indoor environment, which needs to be improved.

[0021] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The embodiment of the present application is a hidden airway strong exhaust drainage sealed casement window structure, and its specific structure is as follows Figure 1-6 shown.

[0025] like Figure 1 and Figure 2 As shown, the structure of the embodiment includes a fixed frame 30 and a first glass frame 10. The fixed frame 30 is used to be installed and fixed in the window of the building. The first glass frame 10 is used to fix the first glass component 40. The first glass component 40 is a movable glass, so the first glass frame 10 can be opened outward relative to the fixed frame 30. When closing the window, the first glass frame 10 rotates inward and is finally placed in the fixed frame 3. Figure 2 As shown, the first glass component 40 is composed of double-layer hollow glass. In other embodiments, the first glass component can also be other forms of glass structures, such as double-layer laminated glass structure, triple-layer hollow / laminated glass structure, single-layer glass structure, etc., without limitation.

[0026] like Figure 2 As shown, when the window is closed, the first glass frame 10 is placed in the fixed frame 30. At this time, a first water flow vertical groove 11 is formed between the left and right outer sides of the first glass frame 10 and the fixed frame 30. Figure 3 and Figure 4As shown, a first water flow horizontal groove 12 is formed between the upper and lower outer sides of the first glass frame 10 and the fixed frame 30, and each first water flow vertical groove 11 is respectively connected to the upper and lower first water flow horizontal grooves 12. Therefore, the accumulated water in the upper first water flow horizontal groove 12, such as condensed water, infiltration water, etc., will flow downward from the first water flow vertical grooves 11 at both ends and finally flow to the lower first water flow horizontal groove 12.

[0027] Combination Figure 2 , Figure 3 and Figure 6 As shown, the fixed frame 30 is provided with two left and right vertical channels 31 and two upper and lower horizontal channels 32, each vertical channel 31 is connected to two upper and lower horizontal channels 32 to form a quadrilateral circulation air channel, and the lower horizontal channel 32 is provided with a side outlet 321 ( Figure 3 ), can be used for gas and water discharge. Figure 2 As shown, the side walls of the two vertical channels 31 are provided with first side holes 311 facing the first water flow vertical groove 11, and the vertical channels 31 are connected to the first water flow vertical groove 11 through the first side holes 311. Figure 3 As shown, a first drain port 121 is provided on the bottom surface of the first water flow groove 12 below, and the first water flow groove 12 is connected to the horizontal channel 32 below through the first drain port 121. Therefore, after the accumulated water flows to the first water flow groove 12 below, it flows into the horizontal channel 32 below through the first drain port 121, and finally is discharged to the outside through the side outlet 321 of the horizontal channel 32.

[0028] It can be seen that the structure of the embodiment forms an excretion channel for airflow and drainage by setting up a circulating air duct connected to the outside of the room and connecting the circulating air duct with the vertical water trough and the horizontal water trough. When strong winds and rainstorms occur, there is an air pressure difference between the circulating air duct, the vertical water trough, the horizontal water trough in the structure and the outdoor environment, which will accelerate the airflow in the circulating air duct, the vertical water trough, and the horizontal water trough. The accelerated airflow can help increase the flow speed of the accumulated water inside, and help the accumulated water inside to be quickly discharged from the side outlet 321 of the horizontal channel 32 below, so that the drainage efficiency is improved, which is beneficial to improving the overall performance and service life of the window.

[0029] In some embodiments, Figure 2 , Figure 3 and Figure 4As shown, a right-angle groove 33 is provided at the opening of the fixed frame 30 facing the outdoors, and an outer seal 13 is fixed to the outside of the first glass frame 10, and the side wings 131 of the outer seal 13 are placed in the right-angle groove 33 and the side wings 131 are close to the surface of the right-angle groove 33 to form a seal. The design of the right-angle groove 33 and the outer seal 13 helps to enhance the sealing performance. By the side wings 131 of the outer seal 13 being close to the surface of the right-angle groove 33, it can effectively prevent the outside air and moisture from penetrating into the window frame, thereby improving the sealing of the casement window. Moreover, the sealing position of the side wings 131 is in the right-angle groove 33, which reduces the convexity of the first glass frame 10 and also reduces the probability of outdoor rainwater penetrating inward from the side wings. The outer seal 13 can be made of common sealing materials, such as rubber, silica gel or other elastic and weather-resistant materials. These materials can ensure that the side wings 131 maintain good sealing performance in long-term use. The size and shape of the right-angle groove 33 can be adjusted according to the specific window frame design.

[0030] In some embodiments, Figure 2 , Figure 3 and Figure 4 As shown, the outer side of the outer seal 13 is provided with a convex strip 132 parallel to the side wing, and a drainage groove 133 is formed between the convex strip 132 and the side wing 131. The setting of the drainage groove 133 can effectively guide rainwater to be discharged along the drainage groove 133, which helps to reduce the rainwater from flowing through the side wing 131 and infiltrating into the window body, reduces the drainage pressure in the structure, and further improves the sealing effect. The convex strip 132 is made integrally with the outer seal 13, such as integral injection molding. During implementation, this structural design can be adaptively adjusted as needed. For example, the height and width of the convex strip 132 can be adjusted according to actual needs to meet different drainage requirements; the depth and shape of the drainage groove 133 can also be optimized according to different needs to obtain a better drainage effect.

[0031] In some embodiments, Figure 2 , Figure 3 and Figure 4As shown, an inner seal 14 is provided in the middle of the outer side of the first glass frame 10, and the inner seal 14 is provided with a folding elastic sheet 141 facing the fixed frame 30, and the fixed frame 30 is correspondingly provided with a corner plate 34 facing the first glass frame 10, and the folding elastic sheet 141 is pressed against the end of the corner plate 34 to form a seal. The cooperation of the inner seal 14 and the folding elastic sheet 141 forms a tight seal between the first glass frame 10 and the fixed frame 30, and the setting of the corner plate 34 provides a stable pressing surface, so that the folding elastic sheet 141 can be effectively pressed against the end of the corner plate 34, thereby achieving a good sealing effect, and realizing the separation of dry and wet areas, reducing the probability of water infiltration into the room. Among them, the inner seal 14 can be made of a flexible material, such as silicone or rubber, to ensure that it has good elasticity and durability. The folding elastic sheet 141 is a part of the inner seal. The corner plate 34 can be made of a metal material to ensure that it has sufficient strength and stability. The installation position and angle of the inner sealing member 14 and the folded elastic sheet 141 can be adjusted according to the specific window frame structure to achieve the best sealing effect.

[0032] In some embodiments, Figure 3 As shown, the bottom of the first glass component 40 is inserted into the bottom cavity 15 of the first glass frame 10, and a water collecting trough 16 is provided below the bottom cavity 15. The water collecting trough 16 is provided below the outer side of the first glass component 40. Below the water collecting trough 16 is a transition groove 17, which is connected to the water collecting trough 16 through an upper hole 171 and is connected to the first water flow horizontal groove 12 below through a lower hole 172. The accumulated water and condensed water infiltrated from the outside of the first glass component 40 can flow into the first water flow horizontal groove 12 through the water collecting trough 16 and the transition groove 17, and finally be quickly discharged through the horizontal channel 32 below, which improves the speed of discharging the infiltrated water and condensed water, and is conducive to reducing the amount of water accumulated in the structure.

[0033] In some embodiments, Figure 4 As shown, the fixed frame 30 is provided with an intermediate crossbeam 39, and the first glass frame 10 is arranged below the intermediate crossbeam 39, and the upper side of the first glass frame 10 and the intermediate crossbeam 39 surround the first water flow horizontal groove 12 above. The fixed frame 30 is provided with the intermediate crossbeam 39, which enhances the strength of the entire structure, improves the overall stability of the frame, and separates the fixed glass above and the movable glass below. The intermediate crossbeam 39 can be made of the same material as the fixed frame 30, such as aluminum alloy, to ensure its strength and corrosion resistance. The intermediate crossbeam 39 can be fixedly connected with the fixed frame 30 through a conventional connection structure, such as a mortise and tenon structure. The design of the intermediate crossbeam 39 can be adjusted according to actual needs, for example, its width and height can be appropriately adjusted according to the size of the fixed frame 30 to ensure the overall strength and drainage effect of the structure.

[0034] In some embodiments, Figure 4 As shown, a middle drainage groove 391 is provided on the outer side of the middle crossbeam 39, and the middle drainage groove 391 is provided with a side drainage port 392 facing the outside. A second glass frame 20 for fixing a second glass assembly 50 is provided above the middle crossbeam 39. The second glass assembly 50 is a fixed glass, that is, the position relative to the fixed frame 30 does not change. The second glass assembly 50 is composed of double-layer hollow glass. In other embodiments, the second glass assembly can also be other forms of glass structures, such as double-layer laminated glass structure, triple-layer hollow / laminated glass structure, single-layer glass structure, etc., without limitation.

[0035] like Figure 5 As shown, a second vertical water flow groove 21 is formed between the left and right outer sides of the second glass frame 20 and the fixed frame 30. Figure 6 As shown, the second glass frame 20 and the fixed frame 30 form a second water flow groove 22. Figure 4 As shown, the third water flow horizontal groove 23 is formed between the lower side of the second glass frame 20 and the middle crossbeam 39, and the second water flow vertical groove 21 is connected to the second water flow horizontal groove 22 and the third water flow horizontal groove 23 respectively. Therefore, the accumulated water flowing into the second water flow horizontal groove 22 will pass through the second water flow vertical groove 21 and enter the third water flow horizontal groove 23 downward, and the bottom surface of the third water flow horizontal groove 23 is provided with a second drain port 231, and the third water flow horizontal groove 23 is connected to the middle drain groove 391 through the second drain port 231, that is, the accumulated water will eventually pass through the second drain port 231 into the middle drain groove 391, and be discharged to the outside through the side drain port 392. In addition, Figure 5 As shown, the side wall of the vertical channel 31 is provided with a second side hole 312, and the vertical channel 31 is connected to the second water flow vertical groove 21 through the second side hole 312, so that the airflow of the circulating airway can enter the second water flow vertical groove 21, the second water flow horizontal groove 22 and the third water flow horizontal groove 23 to flow, which helps to accelerate the flow of accumulated water in the second water flow vertical groove 21, the second water flow horizontal groove 22 and the third water flow horizontal groove 23, and helps to quickly discharge the internal accumulated water from the side outlet of the lower middle drainage groove 391, thereby improving the drainage efficiency.

[0036] In some embodiments, Figure 4 As shown, the bottom surface of the middle drainage groove 391 is a slope 393 and the height of the slope 393 gradually decreases in the direction from indoors to outdoors. The slope 393 is also the surface through which the accumulated water flows outward. This can more effectively guide the accumulated water to flow outdoors, improve the drainage speed and efficiency, and avoid water accumulation and leakage caused by poor drainage. The angle of the slope 393 can be adjusted according to actual needs to ensure the best drainage effect.

[0037] In some embodiments, Figure 4As shown, the bottom of the second glass assembly 50 is inserted into the bottom cavity 24 of the second glass frame 20, and a water collecting trough 25 is provided below the bottom cavity 24. The water collecting trough 25 is provided below the outer side of the second glass assembly 50 to ensure that water can flow directly from the outer side of the second glass assembly 50 to the water collecting trough 25. Below the water collecting trough 25 is a transition groove 26, which is connected to the water collecting trough 25 through an upper hole 261 and is connected to the third water flow horizontal groove 23 below through a lower hole 262. These structures can effectively increase the drainage efficiency and prevent the accumulated water from being retained inside the frame. The accumulated water and condensed water infiltrated from the outside of the second glass assembly 50 can flow into the third water flow horizontal groove 23 through the water collecting trough 25 and the transition groove 26, and finally be quickly discharged through the intermediate drainage groove 391 below, which improves the speed of discharging the infiltrated water and the condensed water, and is conducive to reducing the amount of water accumulated in the structure.

[0038] In some embodiments, Figure 4 , Figure 5 and Figure 6 As shown, the fixed frame 30 is provided with a right angle groove 35 at the opening facing the outdoors, and an outer seal 27 is fixed to the outside of the second glass frame 20, and the side wing 271 of the outer seal 27 is placed in the right angle groove 35 and the side wing 271 is close to the surface of the right angle groove 35 to form a seal. The right angle groove 35 and the outer seal 27 cooperate with each other to help enhance the sealing performance, and the side wing 271 of the outer seal 27 is close to the surface of the right angle groove 35, which can effectively prevent the outside air and moisture from penetrating into the window frame, thereby improving the sealing of the casement window. And the sealing position of the side wing 271 is in the right angle groove 35, which reduces the convexity of the second glass frame 20 and also reduces the probability of outdoor rainwater penetrating from the side wing 271. The outer seal 27 can be made of common sealing materials, such as rubber, silica gel or other materials with elasticity and weather resistance. These materials can ensure that the side wing 271 maintains good sealing performance in long-term use. The size and shape of the right-angle groove 35 can be adjusted according to the specific window frame design.

[0039] In some embodiments, Figure 4 , Figure 5 and Figure 6As shown, an inner seal 28 is provided in the middle of the outer side around the second glass frame 20, and the inner seal 28 is provided with a folding elastic sheet 281 facing the fixed frame 30, and the fixed frame 30 is provided with a corner plate 36 facing the second glass frame 20, and the folding elastic sheet 281 is pressed against the end of the corner plate 36 to form a seal. The design of the inner seal 28 and the folding elastic sheet 281 makes it possible to form a tight seal between the second glass frame 20 and the fixed frame 30, and the corner plate 36 provides a stable pressing surface, so that the folding elastic sheet 281 can be effectively pressed against the end of the corner plate 36, thereby achieving a good sealing effect, and realizing the separation of dry and wet areas, reducing the probability of water infiltration into the room. Wherein, the inner seal 28 can be made of a flexible material, such as silica gel or rubber, to ensure that it has good elasticity and durability. The folding elastic sheet 281 is a part of the inner seal 28. The corner plate 36 can be made of a metal material to ensure that it has sufficient strength and stability. The installation position and angle of the inner seal 28 and the folded elastic sheet 281 can be adjusted according to the specific window frame structure to achieve the best sealing effect.
