Drainage mechanism for concealed drainage doors and windows

Abstract

The present invention discloses a drainage mechanism for concealed drainage doors and windows, which relates to the technical field of doors and windows, and comprises a frame, and a drainage groove is provided below a first drainage port, and further comprises a wind-blocking mechanism for preventing wind from entering the drainage area and affecting drainage during drainage, and a drainage-aiding mechanism for cooperating with the wind-blocking mechanism to promote drainage in windy weather. During use, the drainage mechanism for concealed drainage doors and windows, through the newly provided wind-blocking mechanism, can prevent wind from entering the position of the drainage port in the drainage groove when encountering strong winds and heavy rains, thereby preventing the drainage groove from being affected by the high wind pressure and affecting the normal drainage of rainwater. At the same time, since the wind-blocking mechanism is bidirectionally symmetrical, it can be used for different wind directions. When there is no wind, the drainage paddle will deflect upward under the action of rainwater, thereby not affecting normal drainage. Moreover, in windy weather, the principle of negative pressure can be used to improve drainage efficiency and promote the drainage of rainwater.

Technical Field

[0001] The present invention relates to the technical field of doors and windows, and in particular to a drainage mechanism for concealed drainage doors and windows. Background Art

[0002] The hidden drainage profile has a vertical drainage hole design and is not visible from the outside. Water drains away under the action of gravity, which is a certain advantage. It is popular among customers due to its aesthetics and practicality. However, its unique structure has a fatal disadvantage of rainwater backflow in windy and rainy climates.

[0003] The concealed drainage profile has a vertical drainage hole design and is not visible from the outside. The water drains under the action of gravity, which has certain advantages. It is popular with customers due to its aesthetics and practicality. However, its unique structure has a fatal disadvantage of rainwater backflow in windy and rainy climates. The concealed drainage profile has a concealed drainage structure all around. In windy and rainy weather, water will gather in the hidden drainage groove. Under the action of wind pressure, the water cannot be discharged smoothly. Instead, the water will flow back into the room from the drainage hole along the groove in the hidden drainage groove. The existing hidden drain cover only blocks part of the wind and cannot isolate the wind at the drainage hole. Therefore, when rainwater gathers in the drainage hole, it can still be blown into the drainage hole by the wind and backflow into the room. Summary of the Invention

[0004] The technical solution of the present invention addresses the technical problem that the existing technical solutions are too simple, and provides a solution that is significantly different from the existing technology. The embodiment of the present invention provides a drainage mechanism for hidden drainage doors and windows to solve the technical problem that when the existing hidden drainage doors and windows are in use, when encountering strong winds, the wind pressure will cause the drain outlet to be unable to drain water normally, resulting in backflow.

[0005] The embodiment of the present invention adopts the following technical solution: a drainage mechanism for concealed drainage doors and windows, comprising a frame, a first drainage port being provided in the frame, and a drainage groove being provided below the first drainage port, and further comprising a wind-blocking mechanism for preventing wind from entering the drainage area and affecting drainage during drainage, and a drainage-aiding mechanism for promoting drainage in windy weather in conjunction with the wind-blocking mechanism, wherein the drainage-aiding mechanism is arranged above the wind-blocking mechanism, the drainage-aiding mechanism is arranged in the drainage groove, and is located below the first drainage port, and the drainage-aiding mechanism comprises a drainage-aiding box, which is hollow.

[0006] Furthermore, a drainage box, a central box and a matching component are provided in the middle of the drainage aid box, a second drainage groove is provided in the drainage aid box, the drainage box is hollow, the position of the drainage box corresponds to the position of the drainage groove, the second drainage groove corresponds to the position of the first drainage groove, a matching groove is provided between the drainage box and the central box, and a plurality of air inlets are provided on the central box, and a guide plate is provided on the edge of each of the air inlets, and a guide baffle is provided on the outer wall of the drainage aid box, and the guide baffle is inclined, and the guide baffle is provided at the outer side, a connecting block is provided above the drainage aid box, and the connecting blocks are provided on both sides of the second drainage groove, and the connecting block is engaged in the inner wall of the first drain port.

[0007] Furthermore, the mating assembly includes a plurality of mating baffles, which are rotatably connected in the mating grooves, and limit blocks are provided on both sides of each mating baffle. An inclined plate is provided in the drainage box, and the inclined plate is provided above the mating groove.

[0008] Furthermore, the inclined plate has an inclination angle greater than 100°, and the lower end position of the inclined plate is lower than the highest opening position of the matching groove.

[0009] Furthermore, the windshield mechanism includes a windshield frame, a third drain outlet is provided in the windshield frame, a ventilation drain outlet is provided in the windshield frame, connecting grooves are provided at both ends of the windshield frame, a connecting column is provided in the connecting groove, a drainage paddle is provided outside the connecting column, and the drainage paddle is located in the ventilation drain outlet.

[0010] Furthermore, the first drain outlet, the second drain outlet and the third drain outlet are located in corresponding positions.

[0011] Furthermore, the cross section of the wind shield is U-shaped.

[0012] Furthermore, the cross section of the drainage paddle is inclined, a gap exists between the upper surface of the drainage paddle and the inner wall of the ventilation and drainage port, and the lower end of the drainage paddle contacts the inner surface of the drainage groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The invention can also be used to prevent water from flowing into the drain hole and prevent the water from flowing into the drain hole.

[0015] Secondly, during use, the drainage-aiding mechanism can utilize wind power to promote the circulation of water, thereby promoting the drainage speed of the device. Existing drainage uses the gravity of rainwater to drain water, but when encountering heavy rain and strong winds, the dual effects of wind pressure and drainage volume will cause the drainage efficiency to be too slow, making it impossible for rainwater to be drained in time. At the same time, the drainage outlet has been placed outside for many years, and the drainage outlet may be blocked. When it rains heavily, the drainage of rainwater is not smooth. At this time, the wind will enter the collection box through the guide plate. At this time, the diameter of the collection box is small. When strong winds enter, the wind speed will increase, making the collection box in a negative pressure state compared to the drainage box, thereby playing an adsorption role on the drainage box. The adsorption effect can play a role in dust removal and promote the drainage of rainwater. In the process of use, by setting a rotatable matching baffle, the matching baffle will rotate when wind enters, thereby playing a role in blocking the wind, preventing wind from entering the matching groove, so that the wind will automatically circulate and be discharged through the guide plate;

[0016] To sum up, when the device is in use, the newly set wind blocking mechanism can prevent wind from entering the drainage trough where the drain outlet is located when encountering strong winds and heavy rain. This can avoid the high wind pressure in the drainage trough and affect the normal drainage of rainwater. At the same time, since the wind blocking mechanism is bidirectionally symmetrical, it can target different wind directions. When there is no wind, the drainage paddle will deflect upward under the action of rainwater, thereby not affecting normal drainage. Moreover, in windy weather, the principle of negative pressure can be used to improve drainage efficiency and promote the drainage of rainwater. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the invention.

[0032] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0035] The following combination Figures 1 to 10 As shown, an embodiment of the present invention provides a drainage mechanism for concealed drainage doors and windows, including a frame 1, a first drainage port 12 being provided in the frame 1, and a drainage groove 11 being provided below the first drainage port 12, and a wind shielding mechanism 3 for preventing wind from entering the drainage area and affecting drainage during drainage, and a drainage-aiding mechanism 2 for cooperating with the wind shielding mechanism 3 to promote drainage in windy weather, wherein the drainage-aiding mechanism 2 is arranged above the wind shielding mechanism 3, the drainage-aiding mechanism 2 is arranged in the drainage groove 11, and is located below the first drainage port 12, and the drainage-aiding mechanism 2 includes a drainage-aiding box 23, and the drainage-aiding box 23 is hollow.

[0036] During operation, when the device is in use, through the newly arranged wind shield mechanism 3, when encountering strong winds and heavy rain, the wind shield mechanism 3 can enter the drain outlet and be in the drainage groove 11, thereby avoiding the high wind pressure in the drainage groove 11 and affecting the normal drainage of rainwater. At the same time, since the wind shield mechanism 3 is bidirectionally symmetrical, it can be used for wind in different situations. When there is no wind, the drainage paddle 36 will be deflected upward under the action of rainwater, thereby not affecting normal drainage. Moreover, in windy weather, the principle of negative pressure can also be used to improve drainage efficiency and promote the drainage of rainwater.

[0037] Specifically, a drainage box 212, a centralized box 26 and a matching component are provided in the middle of the drainage box 23. A second drainage groove 11 is provided in the drainage box 23. The drainage box 212 is hollow. The position of the drainage box 212 corresponds to the position of the drainage groove 11. The second drainage groove 11 corresponds to the position of the first drainage groove 11. A matching groove 27 is provided between the drainage box 212 and the centralized box 26. A plurality of air inlets 210 are provided on the centralized box 26. A guide plate 25 is provided on the edge of each of the air inlets 210. A guide baffle 24 is provided on the outer wall of the drainage box 23, and the guide baffle 24 is inclined and is provided at the outer side. A connecting block 21 is provided above the drainage box 23, and the connecting blocks 21 are provided on both sides of the second drainage groove 11. The connecting block 21 is engaged with the inner wall of the first drain port 12.

[0038] Specifically, the mating assembly includes several mating baffles 28, which are rotatably connected in the mating groove 27, and each of the mating baffles 28 is provided with a limit block 211 on both sides, and the drainage box 212 is provided with an inclined plate 29, and the inclined plate 29 is provided above the mating groove 27.

[0039] During operation, the mating baffle 28 will rotate due to the influence of wind, but since a limit block 211 is provided therein and a certain distance is provided between the limit block 211 and the mating baffle 28, the rotation angle of the mating baffle 28 is limited, thereby preventing the mating baffle 28 from rotating too much and causing the mating groove 27 to become closed.

[0040] Specifically, the inclined angle of the inclined plate 29 is greater than 100°, and the lower end position of the inclined plate 29 is lower than the highest opening position of the matching groove 27 .

[0041] During operation, when rainwater flows down, the matching groove 27 can prevent the rainwater from flowing into the matching groove 27 through the inclined plate 29 .

[0042] Specifically, the windshield mechanism 3 includes a windshield frame 32, a third drain outlet 34 is provided in the windshield frame 32, a ventilation drain outlet 31 is provided in the windshield frame 32, connecting grooves 33 are provided at both ends of the windshield frame 32, a connecting column 35 is provided in the connecting groove 33, a drainage paddle 36 is provided outside the connecting column 35, and the drainage paddle 36 is located in the ventilation drain outlet 31.

[0043] Specifically, the first drain outlet 12 , the second drain outlet 22 and the third drain outlet 34 are located correspondingly.

[0044] When working, rainwater can be drained normally.

[0045] Specifically, the wind shield 32 has a U-shaped cross section.

[0046] Specifically, the drainage paddle 36 has an inclined cross section, a gap exists between the upper surface of the drainage paddle 36 and the inner wall of the ventilation and drainage port 31 , and the lower end of the drainage paddle 36 contacts the inner surface of the drainage groove 11 .

[0047] During operation, when there is wind, since the drainage paddle 36 is tilted, the wind will act on the matching paddle, causing the drainage paddle 36 to rotate downward, so that the bottom of the drainage paddle 36 contacts the drainage groove 11, achieving the effect of wind blocking.

[0048] Working principle: When it rains in windless weather, rainwater enters the frame 1 and drains through the drainage groove 11. At this time, the rainwater will flow into the ventilation drainage port 31 in the windshield frame 32 through the drainage groove 11, the first drainage port 12, the second drainage port 22 and the third drainage port 34 in sequence. At this time, the drainage paddle 36 will be rotated upward around the connecting groove 33 through the connecting column 35 under the buoyancy and impact of the rainwater, so that the bottom of the drainage paddle 36 no longer contacts the drainage groove 11, and a gap appears between the drainage paddle 36 and the drainage groove 11. The rainwater is discharged through the ventilation drain outlet 31. When the wind is strong, the wind will first act on the drainage paddle 36, causing the drainage paddle 36 to rotate around the connecting groove 33. The bottom of the drainage paddle 36 is tightly attached to the inner wall of the drainage groove 11. At this time, the wind cannot enter the third drainage outlet 34, thereby avoiding the impact of the wind on the drainage outlet. At this time, the rainwater can be discharged normally by opening the drainage paddle 36 on the other side. Although the wind cannot enter the wind shield frame 32 through the drainage paddle 36, due to the drainage box 2 3 is provided with a guide plate 25, and the drainage box 23 is a hollow setting. At this time, the wind will enter the concentration box 26 through the guide plate 25. At this time, the diameter of the concentration box 26 is small. When strong wind enters, the wind speed will increase, making the concentration box 26 in a negative pressure state compared to the drainage box 212. When rainwater flows into the position of the first drain port 12, the rainwater will be affected by the negative pressure adsorption and be drained. At this time, the discharge of rainwater not only utilizes its own gravity, but is also affected by the negative pressure generated by the wind. Under the dual effect, the drainage of rainwater can be significantly improved. The efficiency is high. At the same time, since the drainage box 212 and the concentration box 26 are staggered during use, the wind will not directly act on the drainage box 212. In addition, by setting a rotatable matching baffle 28, when the wind enters, the matching baffle 28 will rotate, thereby blocking the wind and preventing the wind from entering the matching groove 27. The wind will automatically circulate and be discharged through the guide plate 25, thereby having an adsorption effect on the drainage box 212. The adsorption effect can play a role in dust removal and promote the drainage of rainwater.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
