Detailed Implementation
[0025] The present invention will now be described in further detail with reference to the accompanying drawings.
[0026] refer to Figures 1 to 5A window with a concealed mullion end structure includes a frame assembly 1, within which a first glass body 3, a mullion assembly 2, and a window sash assembly 4 are arranged sequentially; for example, the first glass body 3 can be located above the mullion assembly 2, and the window sash assembly 4 can be located below the mullion assembly 2. Of course, the positions of the first glass body 3 and the window sash assembly 4 can be interchanged.
[0027] The mullion assembly 2 is provided with a water collection tank 21 and a drainage tank 22. The drainage tank 22 is provided with a first drainage hole 221 that communicates with the water collection tank 21. Rainwater and other water collect in the water collection tank 21, then flow to the drainage tank 22, and finally flow to the outside.
[0028] The drainage trough 22 is provided with a drainage windbreak 5, and the drainage windbreak 5 is connected to the first drainage hole 221; the drainage windbreak 5 has a windbreak function, reducing the backflow of water to the water collection trough 21 due to the wind.
[0029] It also includes plugs 7. Both ends of the drainage channel 22 are provided with plugs 7. The plugs 7 can block both ends of the drainage channel 22 to prevent water from flowing into the interior of the mullion assembly 2 or even into the interior of the frame assembly 1, thereby improving the waterproofness and sealing of the mullion assembly 2.
[0030] refer to Figure 5 The plug 7 includes a plugging part 71 and an end piece part 72;
[0031] The blocking part 71 is inserted into the end of the drain groove 22, thereby sealing the end of the drain groove 22 and fixing it by a certain frictional force;
[0032] The end piece 72 is relatively thin and is located between the mullion assembly 2 and the frame assembly 1. This can be understood as the mullion assembly 2 and the frame assembly 1 clamping the end piece 72. This further secures the position of the plug 7; and during disassembly, the end piece 72 can be pulled to remove the plug 7. The plug 7 is made of rubber or soft plastic.
[0033] refer to Figures 6 to 8 The drainage and windbreak component 5 is provided with a panel 51 and a water channel 5a. The water channel 5a is connected to the first drainage hole 221, and a movable baffle 54 is provided at the end of the water channel 5a.
[0034] The drainage and windbreak component 5 is provided with a panel 51 and a water channel 5a. The water channel 5a is connected to the first drainage hole 221, and a movable baffle 54 is provided at the end of the water channel 5a. The end can be understood as the end of the water flow direction.
[0035] After the drainage and windbreak component 5 is assembled, a water channel 5a is formed inside the drainage and windbreak component 5. The drainage process is as follows: water flows from the first drainage hole 221 to the water channel 5a, and then flows along the water channel 5a to the drainage trough 3. When it encounters the influence of external wind, the water may flow back into the water collection trough 2. The function of the drainage and windbreak component 5 is to prevent the occurrence of the above-mentioned backflow or reverse flow. Moreover, the drainage and windbreak component 5 can effectively block the backflow caused by both forward wind and side wind.
[0036] The panel 51 of the drainage windbreak 5 can block the opening of the drainage groove 22. When the wind blows in the right direction, that is, when it blows perpendicular to the panel 51 or the opening, the panel 51 can prevent the wind from blowing in the right direction towards the first drainage hole 221, thereby preventing the wind from driving the water back to the first drainage hole 221.
[0037] The end of the water channel 5a of the drainage and windbreak component 5 is equipped with a movable baffle 54. During normal drainage, refer to Figure 7 The water flow can push the movable baffle 54 to rotate, thereby opening the waterway 5a, allowing the water to flow smoothly into the drainage trough 3; (Reference) Figure 8 When the wind blows from the side toward the first drain hole 221, that is, when the wind blows along the length of the drain trough 22, the movable baffle 54 closes, thereby blocking the airflow and preventing the wind from carrying water back to the water collection trough 21. The movable baffle 54 can close the water channel 5a under the action of the airflow.
[0038] The movable baffle 54 is basically set at an angle, so that when draining water, the water flow can more easily push the movable baffle 54 to rotate, and the lateral airflow can also more easily push the movable baffle 54 to rotate.
[0039] The movable baffle 54 is provided with a rotating shaft 541. The front panel 51 and the rear panel 53 of the drainage and windbreak component 5 are both provided with corresponding shaft holes 50. The top plate 52 of the drainage and windbreak component 5 is provided with a first limiting protrusion 523. The movable baffle 54 is rotatably connected through the rotating shaft 541 structure. The first limiting protrusion 523 is used to limit the position of the rotating shaft 541 and prevent the rotating shaft 541 from disengaging from the shaft hole 50.
[0040] Both the inner sides of the front panel 51 and the rear panel 53 are provided with corresponding second limiting protrusions 542. The second limiting protrusions 542 are used to limit the rotation angle of the movable baffle 54.
[0041] The top plate 52 is provided with a connecting opening 521, which corresponds to the first drainage hole 221;
[0042] The top plate 52 is also provided with a protrusion 522, which can be connected to the first drain hole 221. The protrusion 522 can be fastened to the first drain hole 221 to form a limiting function.
[0043] The connecting port 521 is located in the middle of the waterway 5a, and movable baffles 54 are provided at both ends of the waterway 5a.
[0044] refer to Figure 4 It also includes a drain cover 6, which is located at the opening of the water collection tank 21, and the top wall of the drain cover 6 is provided with a second drain hole 61.
[0045] The drain cover 6 can make rainwater flow through the second drain hole 61 and then into the drain trough 22. It can block dust particles and other debris from flowing into the drain trough 22 to a certain extent, reduce the amount of dust particles flowing into the drain trough 22, reduce the accumulation of dust particles, and reduce the accumulation of dust particles around the first drain hole 221.
[0046] The second drain hole 61 is an elongated hole, and multiple second drain holes 61 are arranged along the length of the drain cover 6.
[0047] A first fastener 211 is provided at the opening of the water collection tank 21, and a second fastener 62 is provided on the side wall of the drain cover 6 to cooperate with the first fastener 211. The two side walls of the drain cover 6 are arranged opposite each other, and each side wall is provided with a second fastener 62. Correspondingly, two first fasteners 211 are arranged opposite each other to realize the fastening assembly.
[0048] The drain cover 6 is made of plastic. Of course, it can also be made of metal.
[0049] The above description only discloses some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
