Description

Technical Field

[0001] This utility model relates to the field of window technology, specifically to a window structure for a double-inward-opening floor drain system. Background Technology

[0002] Double-inward-opening system windows are an energy-saving window design based on an inward-opening structure. Their core advantages lie in their strong sealing performance and ease of cleaning and maintenance. Traditional system windows mainly achieve drainage through water guide channels in the window frame or simple drainage holes. However, such designs are prone to poor drainage due to debris accumulation or extreme weather, which can lead to leakage risks.

[0003] The utility model patent CN218991428U discloses a submersible floor drain for thermally broken aluminum window systems. It includes a frame for the thermally broken aluminum window system, a mounting groove on the frame, a filter plate within the groove, and a drain assembly located below the filter plate. This utility model utilizes the drain assembly to form a detachable, elongated submersible floor drain. Rainwater from the thermally broken aluminum window system is collected and discharged through a side-mounted drain hose. The drain hose can be U-shaped on the exterior wall as needed. The end of the drain hose aligns with the ground, forming a liquid seal to prevent wind and rainwater from entering the pipe and affecting drainage or causing noise. Fixing the filter plate and drain assembly to the frame prevents clogging of the drain assembly. The drain assembly is also detachable for easy replacement.

[0004] Although the existing technologies mentioned above have improved waterproofing and noise reduction through liquid seal design, they still have significant drawbacks: First, the side-mounted drainage hose requires space on the side of the window frame, which not only affects the stability of the window installation but also damages the aesthetics of the building facade; Second, the filter plate is a single-layer filter structure, and the drainage floor drain components are prone to pipe blockage due to the residue of mud or debris, resulting in high long-term maintenance costs. Therefore, there is an urgent need for a double-inward-opening floor drain type drainage system window structure. Utility Model Content

[0005] The purpose of this utility model is to provide a double-inward-opening floor drain window structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A double-inward-opening floor drain type drainage system window structure includes a window frame and a window body hinged to the window frame. The window frame includes an outer frame and an inner frame, and a partition plastic component is provided between the outer frame and the inner frame.

[0008] The outer frame is equipped with a floor drain assembly, which includes a horizontal drainage trough. An insect screen is installed at the outlet of the horizontal drainage trough to prevent small insects from entering. A second rectangular opening is provided at the top of the horizontal drainage trough, and a filter trough is provided inside the second rectangular opening. A frame-shaped support plate is provided on the inner wall of the filter trough near the top. A grid-shaped filter screen is supported on the top of the frame-shaped support plate. The top of the grid-shaped filter screen is on the same plane as the bottom of the drainage trough at the top of the outer frame, ensuring that rainwater can pass through the grid-shaped filter screen and flow into the filter trough. The grid-shaped filter screen filters out larger impurities, while the filter trough filters out smaller impurities, providing dual filtration to prevent the horizontal drainage trough from becoming clogged.

[0009] The outer frame has an installation opening on its outer side for the horizontal drainage channel to pass through, and the top of the outer frame has a first rectangular opening for the filter channel to pass through, ensuring the effective assembly of the floor drain assembly.

[0010] Preferably, a limiting protrusion is provided on the outer wall of the transverse drainage trough at the water outlet end. The side of the limiting protrusion is in contact with the outer side of the outer frame. During installation, the closed end of the transverse drainage trough passes through the installation port into the inner cavity of the outer frame. The limiting protrusion can effectively confirm that the transverse drainage trough is installed in place.

[0011] Preferably, the outer wall of the transverse drainage channel is fitted with a rubber sleeve, the outer wall of the rubber sleeve is tightly fitted with the inner wall of the mounting port, and the outer wall of the rubber sleeve is tightly fitted with the top of the inner cavity of the outer frame, to ensure the sealing of each connection and prevent rainwater from entering the inner cavity of the outer frame.

[0012] Preferably, mounting holes a are provided at the top of the outer frame and at the left and right ends near the first rectangular opening. The floor drain assembly also includes two screws, with the threaded ends of the two screws passing through the two mounting holes a respectively.

[0013] Preferably, the transverse drainage channel is provided with a first internal threaded docking post at both ends. The threaded ends of the two screws are respectively threaded to the two first internal threaded docking posts. The outer walls of the transverse drainage channel and the rubber sleeve are provided with holes for the screws to pass through. The transverse drainage channel and the outer frame are fixed by the two screws to prevent the floor drain assembly from slipping during use.

[0014] Preferably, the bottom of the filter tank and near the left and right ends are provided with support feet, the bottom of the support feet abutting against the bottom of the inner wall of the transverse drainage tank, so that the bottom of the filter tank is reserved with space to avoid interference with the second internal threaded docking post.

[0015] Preferably, filter screens are provided on the front and rear sides of the filter tank, and the filter hole size of the grid-shaped filter screen plate is larger than the filter hole size of the filter tank, so as to achieve dual filtration.

[0016] Preferably, a second internally threaded docking post is provided at the middle of the bottom of the inner wall of the transverse drainage trough, and an installation hole b is provided at the middle of the top of the grid-shaped filter screen. A fastening bolt is connected to the installation hole b. An avoidance hole is provided at the middle of the bottom of the inner wall of the filter trough. The threaded end of the fastening bolt passes through the avoidance hole and is threadedly connected to the second internally threaded docking post. The fastening bolt can be rotated manually to facilitate the user to periodically disassemble and assemble the filter trough and the grid-shaped filter screen, thereby facilitating the cleaning of the filtered material.

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

The window structure of this double-opening floor drain system, through the layered design of the grid-shaped filter screen and the filter tank, effectively intercepts debris such as mud and leaves of different particle sizes, significantly reducing the risk of blockage in the horizontal drainage tank and ensuring the long-term stable operation of the drainage system.

[0019] 2. The double-opening inward-opening floor drain type window structure has a horizontal drainage channel embedded inside the window frame, replacing the traditional exposed drainage hose design. This avoids occupying the side space of the window frame, ensuring the stability of the window installation and improving the overall aesthetics of the building facade.

[0020] 3. The window structure of this double-opening floor drain system allows the grid-shaped filter screen and filter tank to be disassembled by manually rotating the fastening bolts, without the need for tools. This simplifies the cleaning process of the filter components and reduces the difficulty of daily maintenance. Attached Figure Description

[0030] Please see Figures 1-6 This utility model provides a technical solution:

[0031] A double-inward-opening floor drain type window structure includes a window frame 100 and a window body 200 hinged to the window frame 100. The window frame 100 includes an outer frame 110 and an inner frame 120, and a partition plastic part 130 is provided between the outer frame 110 and the inner frame 120.

[0032] The outer frame 110 is equipped with a floor drain assembly 300, which includes a horizontal drainage channel 310. An insect screen 370 is provided at the outlet of the horizontal drainage channel 310 to prevent small insects from entering the horizontal drainage channel 310. A second rectangular opening 314 is provided at the top of the horizontal drainage channel 310. A filter channel 330 is provided inside the second rectangular opening 314. A frame-shaped support plate 333 is provided on the inner wall of the filter channel 330 near the top. A grid-shaped filter screen 340 is supported on the top of the frame-shaped support plate 333. The top of the grid-shaped filter screen 340 is on the same plane as the bottom of the drainage channel at the top of the outer frame 110, ensuring that rainwater can pass through the grid-shaped filter screen 340 and flow into the filter channel 330. The grid-shaped filter screen 340 filters larger impurities, and the filter channel 330 filters smaller impurities. This dual filtration prevents the horizontal drainage channel 310 from becoming clogged.

[0033] The outer side of the outer frame 110 has an installation port 111 through which the horizontal drainage channel 310 passes, and the top of the outer frame 110 has a first rectangular opening 112 through which the filter channel 330 passes, to ensure the effective assembly of the floor drain assembly 300.

[0034] In this embodiment, a limiting protrusion 311 is provided on the outer wall of the transverse drainage trough 310 at the water outlet end. The side of the limiting protrusion 311 fits against the outer side of the outer frame 110. During installation, the closed end of the transverse drainage trough 310 passes through the installation port 111 into the inner cavity of the outer frame 110. The limiting protrusion 311 can effectively confirm that the transverse drainage trough 310 is installed in place.

[0035] Specifically, the outer wall of the transverse drainage channel 310 is fitted with a rubber sleeve 320. The outer wall of the rubber sleeve 320 is tightly fitted with the inner wall of the mounting port 111, and the outer wall of the rubber sleeve 320 is tightly fitted with the top of the inner cavity of the outer frame 110 to ensure the sealing of each connection and prevent rainwater from entering the inner cavity of the outer frame 110.

[0036] Furthermore, mounting holes a113 are provided on the top of the outer frame 110 and near the left and right ends of the first rectangular opening 112. The floor drain assembly 300 also includes two screws 360, with the threaded ends of the two screws 360 passing through the two mounting holes a113 respectively.

[0037] Furthermore, the transverse drainage trough 310 is provided with first internal threaded docking posts 312 at the positions near the left and right ends. The threaded ends of the two screws 360 are respectively threaded to the two first internal threaded docking posts 312. The outer walls of the transverse drainage trough 310 and the rubber sleeve 320 are provided with holes for the screws 360 to pass through. The position of the transverse drainage trough 310 and the outer frame 110 is fixed by the two screws 360 to prevent the floor drain assembly 300 from slipping during use.

[0038] Furthermore, the bottom of the filter tank 330 and near the left and right ends are provided with support feet 331. The bottom of the support feet 331 abuts against the bottom of the inner wall of the transverse drainage tank 310, so that the bottom of the filter tank 330 is reserved to avoid interference with the second internal thread docking post 313.

[0039] Furthermore, filter screens are provided on the front and rear sides of the filter tank 330, and the filter hole size of the grid-shaped filter screen plate 340 is larger than that of the filter hole size of the filter tank 330, so as to achieve dual filtration.

[0040] Furthermore, a second internally threaded docking post 313 is provided at the center of the bottom of the inner wall of the transverse drainage trough 310, and an installation hole b341 is provided at the center of the top of the grid-shaped filter screen 340. The installation hole b341 is connected to a fastening bolt 350. An avoidance hole 332 is provided at the center of the bottom of the inner wall of the filter trough 330. The threaded end of the fastening bolt 350 passes through the avoidance hole 332 and is threadedly connected to the second internally threaded docking post 313. The fastening bolt 350 can be manually rotated so that the user can periodically disassemble and assemble the filter trough 330 and the grid-shaped filter screen 340, thereby facilitating the cleaning of the filtered material.

[0041] In this embodiment, the double-inward-opening floor drain window structure is used by embedding the horizontal drainage channel 310 into the outer frame 110 through the mounting port 111, ensuring that the limiting protrusion 311 is tightly against the outside of the outer frame 110 to confirm that the horizontal drainage channel 310 is installed in place. Next, the user connects the screw 360 to the first internal thread mating post 312 to fix the horizontal drainage channel 310 to the outer frame 110 in place, ensuring that it does not slip during use. At this time, the rubber sleeve 320 is tightly fitted to the inner wall of the mounting port 111 and the top of the inner cavity of the outer frame 110 to achieve good sealing. Then, the filter tank 330 is passed through the first rectangular opening 112 and the second rectangular opening 314 into the horizontal drainage channel 310. The support leg 331 abuts against the bottom of the inner wall of the transverse drainage channel 310. Then, the user passes the fastening bolt 350 through the mounting hole b341 and the clearance hole 332 in sequence and connects it with the second internal thread mating post 313, thereby fixing the position of the grid-shaped filter screen 340, the filter channel 330 and the transverse drainage channel 310. When rainwater enters the drainage channel of the outer frame 110, the rainwater is filtered by the grid-shaped filter screen 340 and the filter channel 330 in sequence. After two filtrations, it is discharged from the transverse drainage channel 310, effectively preventing the transverse drainage channel 310 from becoming clogged. The user needs to disassemble the filter channel 330 and the grid-shaped filter screen 340 regularly for cleaning to ensure the effectiveness of the dual filtration function and the smooth operation of the drainage system.
