Description

Technical Field

[0001] This utility model relates to the field of door and window profile technology, and in particular to a drainage structure for door and window profiles. Background Technology

[0002] In the field of building doors and windows, especially in the application of casement windows, drainage performance has always been a key factor affecting the overall quality and service life of doors and windows. As modern buildings have increasingly stringent requirements for waterproofing and moisture-proofing, the drainage design of door and window profiles is receiving more and more attention.

[0003] Currently, the drainage measures used in domestic sliding windows are not well considered, and the drainage structure is difficult to meet the purpose of smooth drainage. Although some sliding window drainage structures can achieve smooth drainage, they are generally not well considered. In strong winds, water can still flow inside the sliding window frame and cannot be drained.

[0004] An existing patent (publication number: CN215632615U) discloses a drainage system for door and window frame profiles. When this utility model is affected by wind, the accumulated water flows towards the interior on the track profile with the help of the wind, and flows into the drainage chamber from the first and second drainage holes. Finally, it is discharged out of the window from the fourth drainage hole of the drainage platform. This drainage structure is more thorough and faster than that of traditional sliding windows, and there is no water accumulation.

[0005] To address the aforementioned issues, existing patents offer solutions. However, while most casement window profiles on the market incorporate drainage holes, their placement and detailing are flawed. Typically, these drainage holes are located below the opening section of the frame, near the edge, and run horizontally through the profile. This design significantly reduces drainage stability, especially during heavy rain. Because the drainage holes are horizontal, rainwater struggles to drain quickly and smoothly under gravity, leading to water accumulation inside the profile. Prolonged water retention creates a constantly damp environment inside the profile, easily causing corrosion. This not only drastically shortens the profile's lifespan but, more seriously, can leak into the interior, damaging interior decoration and causing considerable inconvenience and financial loss for users.

[0006] Therefore, a drainage structure for door and window profiles is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a drainage structure for door and window profiles, which can solve the problem that, although drainage holes are generally provided in existing casement window profiles on the market, there are obvious defects in their location and details. Usually, the drainage holes are often opened below the opening part of the opening frame, near the edge, and run horizontally through the profile. This design greatly reduces the stability of drainage. Especially in rainy weather, because the drainage holes are horizontal, rainwater is difficult to drain quickly and smoothly under the action of gravity, resulting in water accumulation inside the profile cavity. The water stagnation for a long time will keep the inside of the profile in a humid environment, which will easily cause corrosion problems. This not only greatly shortens the service life of the profile itself, but more seriously, the water may also leak into the room, damaging the interior decoration and causing many troubles and economic losses to users.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a drainage structure for door and window profiles, comprising a profile body, wherein a drainage mechanism is provided on the right side inside the profile body;

[0009] The drainage mechanism includes an arc-shaped drainage hole, a guide cavity, and a water guiding structure. The arc-shaped drainage hole is located at the bottom right side of the profile body. The guide cavity is located on the right side of the profile body and is connected to the arc-shaped drainage hole. The water guiding structure is located inside the guide cavity and at the bottom of the arc-shaped drainage hole.

[0010] Preferably, the water guiding structure includes a water guiding plate fixedly connected inside the guiding cavity groove, the water guiding plate being in an inclined state and located at the bottom of the arc-shaped drainage hole.

[0011] Preferably, a baffle plate is fixedly connected to the bottom of the water guide plate, and the bottom of the baffle plate is fixedly connected to the bottom side inside the guide cavity groove.

[0012] Preferably, both the water guide plate and the baffle plate have drainage grooves on their right sides, and the drainage grooves are semi-circular arc-shaped.

[0013] Preferably, a water channel is provided at the bottom right side of the profile body, and the water channel is connected to the arc-shaped drainage hole.

[0014] Preferably, a groove is provided at the bottom right side of the profile body, and the groove communicates with the arc-shaped drainage hole.

[0015] Preferably, a baffle is fixedly connected to the right side of the top side inside the guide cavity, and the baffle is located on the right side of the water guide plate and the baffle plate.

[0016] Preferably, the right side of the water guide plate and the baffle plate is coated with a superhydrophobic coating, which is made of a fluoropolymer material.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application incorporates a drainage mechanism, in which the arc-shaped drainage hole breaks through the limitations of traditional horizontal drainage hole design. Following the principle of rainwater gravity diversion, it is opened at the bottom right side inside the profile body, which facilitates the rapid collection and discharge of rainwater, effectively preventing water accumulation. At the same time, the guide cavity is connected to the arc-shaped drainage hole, which can promptly guide rainwater, widen the drainage path, and greatly enhance drainage stability. Even in torrential rain, it can ensure that there is no water accumulation inside the profile body, significantly reducing the risk of profile corrosion due to moisture, extending service life, and eliminating the hidden danger of water leakage damaging indoor decoration, effectively protecting the user's living experience and reducing economic losses.

[0019] 2. This application sets up a water guiding structure, which is precisely positioned in the guiding cavity and located at the bottom of the arc-shaped drainage hole. It works in a clever way with the arc-shaped drainage hole and the guiding cavity, which can finely control the direction of rainwater flow, so that the rainwater flows faster along the inclined path, thereby further improving drainage efficiency and ensuring smooth drainage, so that the drainage mechanism of the profile body can operate stably for a long time.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A drainage structure for a door and window profile includes a profile body 1, and a drainage mechanism 2 is provided on the right side inside the profile body 1.

[0029] The drainage mechanism 2 includes an arc-shaped drainage hole 21, a guide cavity 22, and a water guiding structure 23. The arc-shaped drainage hole 21 is located at the bottom right side of the profile body 1. The guide cavity 22 is located on the right side of the profile body 1 and communicates with the arc-shaped drainage hole 21. The water guiding structure 23 is located inside the guide cavity 22 and at the bottom of the arc-shaped drainage hole 21.

[0030] In this embodiment: By setting up a drainage mechanism 2, when rainwater enters the interior of the profile body 1, it will flow along the profile body 1 under the action of gravity. Since the arc-shaped drainage hole 21 is opened at the bottom right side of the interior of the profile body 1, the rainwater can naturally converge here. The arc design cleverly utilizes the principle of hydrodynamics, allowing the rainwater to form a concentrated flow at the bottom, accelerating the flow to the guide cavity 22. The guide cavity 22 is connected to the arc-shaped drainage hole 21, like a dedicated channel for rainwater, which promptly receives and guides the converged rainwater, widening the rainwater evacuation path. The water guiding structure 23 is located in the guide cavity 22 at the bottom of the arc-shaped drainage hole 21. It uses its special structure to further refine the flow direction of the rainwater, allowing it to be discharged quickly along the preset optimal inclined path, avoiding the rainwater from meandering and stagnating inside the profile body 1, thereby ensuring the continuous and efficient operation of the entire drainage mechanism 2 and ensuring smooth and worry-free drainage of the profile body 1.

[0031] Specifically, such as Figure 3 As shown, the water guiding structure 23 includes a water guiding plate 231 fixedly connected inside the guiding cavity 22. The water guiding plate 231 is in an inclined state and is located at the bottom of the arc-shaped drainage hole 21.

[0032] Specifically, such as Figure 3 As shown, a baffle plate 232 is fixedly connected to the bottom of the water guide plate 231, and the bottom of the baffle plate 232 is fixedly connected to the bottom side inside the guide cavity 22.

[0033] Specifically, such as Figure 3As shown, both the water guide plate 231 and the baffle plate 232 have drainage grooves 233 on their right sides, and the drainage grooves 233 are semi-circular arc-shaped.

[0034] In this embodiment: by setting up a water guiding structure 23, when rainwater flows through the arc-shaped drainage hole 21 into the guiding cavity 22, the inclined water guiding plate 231 plays a key guiding role. Based on gravity and slope, it helps the rainwater to accelerate down the slope, accurately changing the direction of the rainwater flow and making it rush along the preset path. At the same time, the deflector plate 232 fixedly connected at the bottom further adjusts the direction of the water flow, avoiding vertical impact of rainwater and causing turbulence, ensuring that the water flow is stable and orderly. In addition, the semi-circular arc-shaped drainage channel 233 opened on the right side of both guides the rainwater, allowing the rainwater to pass through in a more concentrated and faster state, greatly improving drainage efficiency and ensuring that the drainage process is completed in one go.

[0035] Specifically, such as Figure 1 As shown, a water channel 3 is provided at the bottom right side of the profile body 1, and the water channel 3 is connected to the arc-shaped drainage hole 21.

[0036] Specifically, such as Figure 1 As shown, a groove 4 is provided at the bottom right side of the profile body 1, and the groove 4 is connected to the arc-shaped drainage hole 21.

[0037] In this embodiment: by setting up a water-guiding trough 3 and a groove 4, they are connected with the arc-shaped drainage hole 21 to form a precise rainwater collection network. With its reasonable trough design, the water-guiding trough 3 can guide and collect rainwater on a large scale when it enters the bottom right side of the profile body 1, and quickly guide it to the arc-shaped drainage hole 21. The groove 4 will quickly guide the rainwater flowing to the arc-shaped drainage hole 21. In this way, it assists the arc-shaped drainage hole 21 to complete the initial concentration of rainwater, providing sufficient and orderly water flow for the subsequent drainage process, making the entire early drainage work efficient and smooth.

[0038] Specifically, such as Figure 2 As shown, a baffle 5 is fixedly connected to the right side of the top side inside the guide cavity 22. The baffle 5 is located on the right side of the water guide plate 231 and the flow deflector 232.

[0039] Specifically, such as Figure 5 As shown, the right side of the water guide plate 231 and the flow deflector plate 232 is coated with a superhydrophobic coating 6, which is made of a fluoropolymer material.

[0040] In this embodiment: by setting baffle 5 and superhydrophobic coating 6, when rainwater rushes to the right side of water guide plate 231 and flow deflector 232, baffle 5 blocks the splashed water and at the same time blocks the water guide plate 231 and flow deflector 232, improving their overall aesthetics. The superhydrophobic coating 6 utilizes the extremely low surface energy characteristics of fluoropolymer material, allowing rainwater to instantly form water droplets and quickly roll off when it comes into contact with the surface of water guide plate 231 and flow deflector 232. This not only accelerates its own flow speed but also washes away some tiny adhering objects, keeping the surface clean. With this dual protection, the drainage is smoother and more stable.

[0041] Working Principle: During actual use of the door and window profiles, when rainwater enters the interior of the profile body 1, it flows smoothly along the profile body 1 due to gravity. At this time, the water-guiding channel 3 and groove 4 connected on the bottom right side of the profile body 1 quickly guide and collect the rainwater, directing it to the arc-shaped drainage hole 21. The arc-shaped drainage hole 21, with its arc-shaped design at the bottom, cleverly utilizes water dynamics to allow the rainwater to quickly form a concentrated flow, accelerating it into the guide cavity 22 connected to it. After the rainwater enters the guide cavity 22, the inclined water-guiding plate 231 precisely changes the direction of the water flow according to gravity and slope, helping the rainwater to accelerate down the slope. The deflector plate 232 at the bottom further optimizes the water flow direction and avoids... To prevent turbulence, the semi-circular drainage channel 233 on the right side of both acts like a high-speed track, allowing rainwater to flow in a more concentrated and high-speed manner, greatly improving drainage efficiency. At the same time, the baffle 5 on the top right side of the guide cavity 22 not only effectively blocks rainwater splashes but also shields the water guide plate 231 and the flow deflector 232, enhancing its overall aesthetics. Furthermore, the fluoropolymer superhydrophobic coating 6 on the right side of the water guide plate 231 and the flow deflector 232 utilizes its extremely low surface area to allow rainwater to instantly form beads and roll off, accelerating the flow rate and carrying away tiny adhering objects. This overall collaboration ensures continuous and efficient guidance and discharge of rainwater under various weather conditions, guaranteeing smooth and worry-free drainage of the profile body 1.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
