Description

Technical Field

[0001] This utility model relates to the technical field of door and window structures, specifically to a mullion structure and a door / window. Background Technology

[0002] Windows are an essential component of buildings, providing ventilation and lighting for rooms. However, over time, the sealing strips on the sides of the glass age, significantly reducing their sealing effectiveness. During rainy days, rainwater flows through these aged strips into the window frame, accumulating and becoming difficult to drain. Prolonged immersion in water shortens the window's lifespan and can also breed harmful substances. While existing windows are equipped with drainage holes in the frame to prevent water accumulation, in severe weather conditions like heavy rain, the holes may not be able to drain the large amounts of water in time. This can lead to water accumulating again in the frame and track, and the accumulated water can easily backflow due to external airflow, causing flooding or wall damage. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with its embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit its scope of protection.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0033] On the one hand, such as Figure 1 and Figure 2 As shown, a mullion structure in one embodiment of the present invention includes:

[0034] The horizontal connecting component 1 is set on the window frame 3 and is used to divide the inner frame space of the window frame 3;

[0035] The mullion connecting assembly 2 is connected to the transverse connecting assembly 1 by a snap-fit ​​structure 4. The mullion connecting assembly 2 is provided with a drainage channel 21 arranged from top to bottom, and the drainage inlet 201 of the drainage channel 21 is provided with a guide baffle 22.

[0036] The aforementioned mullion structure, by setting a drainage channel 21 arranged from top to bottom on the mullion connecting component 2, uses a guide baffle 22 to guide outdoor rainwater to the drainage inlet 201 of the drainage channel 21, thereby reducing the possibility of rainwater backflowing into the room; at the same time, since the drainage channel 21 is set inside the mullion connecting component 2, the size of the drainage channel 21 can be adjusted according to needs, thereby improving the drainage function of the doors and windows.

[0037] Specifically, utilizing the force of gravity, water is rapidly discharged along the vertically downward drain holes, resulting in strong and smooth drainage. Simultaneously, the vertically downward design effectively prevents rainwater backflow caused by strong winds blowing directly into the drain holes.

[0038] In one embodiment, the mullion connecting assembly 2 includes a mullion profile 23 connected to the transverse connecting assembly 1; the snap-fit ​​structure 4 includes a snap-fit ​​groove 41 on the transverse connecting assembly 1 and a snap-fit ​​flange 42 on the mullion profile 23. Thus, the mullion profile 23 is detachably installed by snapping the snap-fit ​​flange 42 onto the snap-fit ​​groove 41, facilitating maintenance and replacement when the drainage channel 21 becomes blocked or fails to meet usage requirements.

[0039] In one embodiment, the connection surface between the mullion profile 23 and the transverse connecting assembly 1 is V-shaped, and the cross-sectional area of ​​the drainage channel 21 is triangular. Thus, the triangular channel cavity facilitates the drainage of rainwater from the drainage channel 21.

[0040] In one embodiment, the drainage inlet 201 and the drainage outlet 202 are not in the same vertical direction, and the triangular channel cavity is provided with a water storage space; the water storage space is formed by the extruded edge of the mullion profile 23 or by a hardened adhesive material. In this way, some rainwater is stored through the water storage space to prevent rainwater from overflowing from the drainage inlet 201 due to excessive rainfall.

[0041] Specifically, the drainage holes of drainage channel 21 are cleverly concealed within the inner cavity of the mullion, which not only enhances the overall aesthetics of the doors and windows but also avoids potential safety hazards caused by exposed drainage holes. At the same time, the water storage space can also buffer and regulate rainwater to some extent, helping to reduce the pressure on the drainage system during heavy rain.

[0042] In one embodiment, the snap-fit ​​structure 4 includes two snap-fit ​​flanges 42 respectively disposed on the two inclined surfaces of the V-shaped surface; the snap-fit ​​flanges 42 are provided with mounting deformation cavities. Thus, by pressing the snap-fit ​​flanges 42 to deform towards the mounting deformation cavities, the snap-fit ​​flanges 42 are inserted into the snap-fit ​​grooves 41. After the external force is removed, the mounting deformation cavities return to their original state, and the snap-fit ​​flanges 42 are locked into the snap-fit ​​grooves 41.

[0043] On the other hand, such as Figure 1 and Figure 2 , Figure 3 As shown, a door and window according to one embodiment of the present invention includes a window frame 3, a fixed glass sash 5, a movable window sash 6, and a mullion structure. The window frame 3 has a first installation space 301 and a second installation space 302 disposed above the first installation space 301. The horizontal connecting component 1 is used to separate the first installation space 301 and the second installation space 302. The fixed glass sash 5 is installed in the first installation space 301. The movable window sash 6 is movably installed in the second installation space 302. Thus, the mullion structure facilitates the drainage of rainwater entering from the installation gap between the movable window sash 6 and the horizontal connecting component 1 through the drainage channel 21 to the fixed glass sash 5, thereby preventing rainwater from seeping into the room from the second installation space 302.

[0044] In one embodiment, the drain outlet 202 of the drainage channel 21 is inclined toward the fixed glass panel 5. Thus, since the part where the upper edge of the fixed glass panel 5 is connected to the transverse connecting assembly 1 is usually difficult to be washed away by rainwater and is likely to be covered with dust, the fixed glass panel 5 is cleaned by letting rainwater flow from the drain outlet 202 of the drainage channel 21 onto the upper part of the fixed glass panel 5.

[0045] In one embodiment, a sealing strip is provided between the movable window sash 6 and the window frame 3 to form an isobaric cavity structure with a watertight chamber on the outside and an airtight chamber on the inside; the pressure inside the isobaric cavity is equal to the outdoor pressure, which can effectively prevent rainwater from entering the room under the action of pressure difference.

[0046] In one embodiment, the drainage inlet 201 of the drainage channel 21 is equipped with a filter screen. In this way, the filter screen isolates debris such as leaves and pebbles mixed in with rainwater, preventing debris from clogging the drainage channel 21 and affecting the drainage function.

[0047] In one embodiment, the lateral connecting assembly 1 includes a first connecting profile 11, a second connecting profile 12, and a thermal break connecting unit 13 connecting the first connecting profile 11 and the second connecting profile 12. Thus, the thermal break connecting unit 13 improves the thermal insulation function, thereby facilitating the assembly of the second connecting profile 12.

[0048] In one embodiment, a screen fan 8 is also included, disposed in the second installation space 302, the screen fan 8 being located on the side of the movable window sash 6 facing the interior. Thus, the screen fan 8 facilitates the isolation of mosquitoes when the movable window sash 6 is open, ensuring a better user experience.

[0049] In one embodiment, the window frame 3 includes a lower frame profile 31 disposed below the fixed glass sash 5, and the outer side of the lower frame profile 31 is provided with a second drainage channel 303. Specifically, the fixed glass sash 5 is connected to the lower frame profile 31 by a sealing strip. Thus, when the sealing strip ages after long-term use, rainwater flows from the fixed glass sash 5 and falls into the gap between the sealing strip and the fixed glass sash 5, thereby entering the second channel 303 of the lower frame profile 31 for drainage; at the same time, because the sealing strip is in close contact with the fixed glass sash 5, the rainwater is prevented from flowing back into the room through the drainage hole of the second channel 303 due to the spatial air pressure inside the lower frame profile 31, thereby ensuring a dry and safe indoor environment.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
