Description

Technical Field

[0001] This invention relates to the field of inward-opening window technology, specifically to a double-drip water-guiding structure along a layered water-guiding structure and an inward-opening window sash device containing this structure. Background Technology

[0002] With the development of building door and window technology, the structure of door and window frames generally emphasizes heat insulation and sealing performance. In actual use, the temperature difference between indoors and outdoors can easily cause condensation inside the frame. At the same time, in heavy rain or storms, rainwater may seep into the joints and sealing gaps of the frame. Therefore, door and window frames usually need to be equipped with drainage structures.

[0003] However, existing door and window frame drainage structures still have the following drawbacks in practical use: Existing door and window drainage structures mostly use a single drainage channel to discharge both rainwater and condensate. During heavy rain, a large amount of external rainwater enters the drainage channel, which can easily prevent the condensate generated inside from draining smoothly, and may even cause rainwater to backflow into the frame. When the inward-opening window is rotated open, the drain outlet inside the frame is usually exposed. Dust, sand, and fallen leaves from the outside can easily fall into the drain pipe, causing blockage over time and affecting subsequent drainage performance. Traditional drainage holes or drainage channel outlets lack effective backflow prevention protection. In strong winds outdoors, wind can easily blow directly back into the frame cavity along the drainage channel, generating wind noise and even blowing accumulated water back into the room. Summary of the Invention

[0004] In order to overcome the above-mentioned technical problems, the present invention aims to provide a double-drip water guiding structure along a layered water guiding structure and an inward-opening window sash device containing the structure, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A dual-channel drip edge layered water guiding structure includes a bottom frame and an openable fan frame rotatably connected to the bottom frame. The structure further includes: a front frame disposed at the openable fan frame, the bottom of which has drip edge one and drip edge two for discharging different water sources respectively; a dual-channel section disposed below the bottom frame, the dual-channel section forming water channel one and water channel two for layered water guiding; a rubber diverter disposed between the dual-channel section and the openable fan frame for guiding liquid falling from drip edge two into water channel two; and a windproof component disposed at the dual-channel section for unidirectionally blocking the outlets of water channel one and water channel two.

[0006] Preferably, the front frame has a liquid outlet one and a liquid outlet two, and the bottom of the front frame is inclined toward the drip edge two, so that the liquid flowing out from the liquid outlet one and the liquid outlet two flows along the inclined surface to the drip edge two.

[0007] Preferably, the opening fan frame further includes a rear frame with glass installed, and a heat-insulating seal installed between the front frame and the rear frame.

[0008] Preferably, the bottom frame includes an upper bottom frame, a front bottom frame installed at the bottom of the upper bottom frame, a rear bottom frame, and a second heat-insulating sealing member installed between the front bottom frame and the rear bottom frame.

[0009] Preferably, the top of the upper bottom frame is provided with a rubber pad for contacting the bottom side of the front frame, and the liquid that seeps into the rubber pad drips down into the water channel through the dripping point along a guide.

[0010] Preferably, the dual-channel section includes an upper channel shell, a middle channel shell, and a lower channel shell, with the upper channel shell and the middle channel shell forming the first channel, and the middle channel shell and the lower channel shell forming the second channel.

[0011] Preferably, the rubber diverter is installed on the top of the middle casing; when the opening fan frame is rotated to the closed state, the front frame presses the rubber diverter to deform, causing its end to stop below the drip edge.

[0012] Preferably, when the opening fan frame is rotated to the open state, the rubber diverter elastically resets and adheres to the two sides of the heat insulation seal to block the liquid inlet of the second water channel.

[0013] Preferably, the rubber diverter has a connecting hole, and two blocking blades are provided at both ends of the connecting hole to divert the water into the second waterway when the water in the first waterway reaches a set height.

[0014] Preferably, the windproof component is installed at the bottom of the middle casing, and the windproof component has a front blade body that blocks the waterway outlet one and a rear blade body that blocks the waterway outlet two, respectively.

[0015] Preferably, both the front blade and the rear blade are arc-shaped structures and are respectively attached to the upper casing and the lower casing; the windproof component is detachably installed on the middle casing.

[0016] Compared with the prior art, the beneficial effects of the present invention are: By setting two drip edges at the bottom of the front frame of the opening fan section, combined with the compressible rubber diverter and the dual water channel section, the condensate generated inside and the rainwater that seeps in from the outside can be guided to different water channels for discharge, effectively reducing the mutual interference between rainwater and condensate and avoiding water accumulation inside. When the window sash is open, the rubber diverter can elastically reset and fit against the side of the thermal insulation seal, actively blocking the inlet of the condensate water channel to prevent external dust and impurities from falling into the condensate water channel and causing blockage. By installing a windproof component with an arc-shaped blade at the outlet of the dual waterway, the blade is pressed tightly against the shell wall when the outdoor wind blows back, blocking the backflow of wind and rain; when there is water inside, the gravity of the water flow can push the blade open to drain the water smoothly. A connecting hole with a blocking arc blade is set on the rubber diverter. When the main rainwater channel is accidentally blocked and the water level rises, rainwater can overflow through the connecting hole to the condensate channel and be discharged, reducing the risk of water flooding into the room. At the same time, the windproof component adopts a detachable structure, which is convenient for later disassembly, flushing and unblocking. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] One embodiment provided by the present invention: refer to Figure 1 As shown, the double-channel dripping water is arranged along a layered water guiding structure, which includes a glass 01, an openable fan frame 02, a bottom frame 03, and a double water channel 04.

[0021] refer to Figures 1-5 As shown, the glass 01 is installed in the opening sash frame 02, which includes a front frame 21, a rear frame 22, and a heat insulation seal 23. The heat insulation seal 23 is installed between the front frame 21 and the rear frame 22.

[0022] The front frame 21 has a liquid outlet 1 211 and a liquid outlet 212. The front frame 21 is located in the window facing outward. In actual use, the external temperature is high and the temperature inside the front frame 21 is low, which will produce condensate. The condensate can be discharged from the bottom of the front frame 21 through the liquid outlet 1 211 and the liquid outlet 212.

[0023] The bottom of the front frame 21 is also provided with a first drip edge 213 and a second drip edge 214. The first drip edge 213 is used to guide external rainwater to drip down, and the second drip edge 214 is used to guide internal condensate to drip down.

[0024] The bottom surface of the front frame 21 is inclined toward the drip edge 214. The condensate flowing out of the front frame 21 will drip down along the inclined surface from the drip edge 214 under the action of gravity. When the rainwater flows in between the front frame 21 and the upper bottom frame 31, it can only drip down from the drip edge 213 into the upper bottom frame 31.

[0025] The bottom frame 03 includes an upper bottom frame 31, a front bottom frame 32 is installed at the bottom of the upper bottom frame 31, a second thermal insulation seal 34 is installed on the side of the front bottom frame 32, a rear bottom frame 33 is installed on the side of the second thermal insulation seal 34, the second thermal insulation seal 34 is installed between the rear bottom frame 33 and the front bottom frame 32, and the first thermal insulation seal 23 and the second thermal insulation seal 34 cooperate to seal the window sash.

[0026] A rubber pad is provided at the top of the upper bottom frame 31. This rubber pad is used to contact the bottom side of the front frame 21 to partially block rainwater. In the event of heavy rain or storm, this rubber pad cannot completely block rainwater, and rainwater may seep in. The seeping rainwater will drip down through the drip line 213 to the lower double water channel section 04.

[0027] The entire bottom frame 03 is fixed, while the glass 01 and the opening sash frame 02 are rotatably connected to the bottom frame 03, and the glass 01 and the opening sash frame 02 can be rotated to open.

[0028] The dual-channel section 04 includes an upper channel shell 42, a middle channel shell 43, and a lower channel shell 44. The upper channel shell 42 and the middle channel shell 43 are connected by a bridge frame, and the upper channel shell 42 and the middle channel shell 43 form a first channel 46. The middle channel shell 43 and the lower channel shell 44 are connected by a bridge frame, and the middle channel shell 43 and the lower channel shell 44 form a second channel 47.

[0029] A windproof component 45 is installed at the bottom of the middle casing 43. A front blade 451 and a rear blade 452 are respectively provided on both sides of the windproof component 45. The front blade 451 blocks the outlet of waterway one 46, and the rear blade 452 blocks the outlet of waterway two 47. The front blade 451 and the rear blade 452 are both arc-shaped and are respectively attached to the upper casing 42 and the lower casing 44.

[0030] The rubber diverter 41 is installed on the top of the middle shell 43. When the inner window is opened, the rubber diverter 41 is attached to the side of the heat insulation seal 34. When the inner window is closed, the rotating and resetting front frame 21 will cause the rubber diverter 41 to deform. Due to the length limitation of the rubber diverter 41, the end of the rubber diverter 41 will stay at the drip edge 214.

[0031] The design of the rubber diverter 41 is such that when the inward-opening window is open, the rubber diverter 41 fits against the heat insulation seal 34, thereby blocking the liquid inlet of the water channel 47. External rainwater and other impurities may fall into the opening fan frame 02 and the double water channel 04, preventing the impurities carried by the rainwater from flowing into the water channel 47. When the inward-opening window is closed, the internal condensate can only flow from the front frame 21 through the liquid inlet 211 and the liquid inlet 212 to the right side of the rubber diverter 41 and then be guided to the liquid inlet of the water channel 47, and finally discharged through the other end of the water channel 47.

[0032] The arc-shaped design of the front blade 451 and the rear blade 452 ensures that when the wind blows the front blade 451 and the rear blade 452, they fit tightly against the upper casing 42 and the lower casing 44, preventing the wind from blowing directly back into the double water channel section 04. When rainwater or condensate needs to be discharged, it will push the front blade 451 and the rear blade 452 to deform and discharge the water.

[0033] refer to Figure 5 As shown, the rubber diverter 41 is also provided with a connecting hole 411. Two blocking arc blades are provided at both ends of the connecting hole 411. When the liquid flows normally from the rubber diverter 41, it prevents rainwater or condensate from passing through. However, during long-term use, such as when the window is open, the water channel 46 is blocked by impurities. After the window is closed, the rainwater that seeps in cannot be effectively discharged from the blocked water channel 46. The accumulated rainwater will accumulate between the heat insulation seal 34 and the rubber diverter 41. When it reaches the height of the connecting hole 411, the rainwater can flow into the condensate drain channel through the connecting hole 411.

[0034] If a blockage is found in waterway 46 later, simply remove the windproof part 45 from the middle casing 43 and then flush waterway 46 with water.

[0035] Working principle: 1. Condensation and rainwater are separated and drained when the window is closed: When glass 01 and the opening fan frame 02 rotate relative to the bottom frame 03 to the closed state: Under the influence of the internal and external temperature difference, the condensate generated inside the front frame 21 flows out sequentially through liquid outlet 1 211 and liquid outlet 212 to the bottom of the front frame 21. Since the bottom surface of the front frame 21 is inclined towards the drip edge 214, the condensate flows along the inclined surface to the drip edge 214 under the action of gravity.

[0036] During this process, the rotating and resetting front frame 21 compresses the rubber diverter 41, causing it to deform. Due to the length limitation of the rubber diverter 41 itself, its end stops at the drip edge 214. The condensate dripping from the drip edge 214 falls into the right side of the rubber diverter 41 and is precisely guided to the inlet of the water channel 47. Finally, it flows along the water channel 47 and pushes open the rear blade 452 of the windproof component 45 to be discharged.

[0037] When external rainwater flows in between the front frame 21 and the upper bottom frame 31, the rubber pad at the top of the upper bottom frame 31 blocks most of the rainwater. In the event of heavy rain or torrential rain, the rainwater passes over the rubber pad and drips from the drip edge 213 to the left side of the rubber diverter 41 in the dual water channel section 04, directly entering the water channel 46, and then pushes open the front blade 451 to discharge, thus realizing the separation of condensate and rainwater in the pipe bundle.

[0038] 2. Anti-fouling protection when the window sash is open: When the glass 01 and the opening window frame 02 rotate to open: The front frame 21 releases pressure on the rubber diverter 41, and the rubber diverter 41 elastically returns to its original position, adhering to the side of the heat insulation seal 34. At this time, the rubber diverter 41 completely blocks the inlet of the second water channel 47 (condensate channel). When rainwater or dust containing impurities falls into the area between the opening fan frame 02 and the double water channel 04, it cannot enter the second water channel 47, effectively preventing silt blockage in the dedicated condensate channel.

[0039] Pneumatic windproof and backflow prevention: When external wind forces act on the 04 outlet of the dual-channel section: The windproof component 45 is installed at the bottom of the middle shell 43. Its front blade 451 and rear blade 452 are arc-shaped and fit tightly against the upper shell 42 and lower shell 44, respectively. When strong outdoor wind blows back, the wind pressure acts on the arc-shaped outer skin of the front blade 451 and rear blade 452, making them fit more tightly against the corresponding shell wall, preventing wind and rain from flowing back into the water channel 1 46 and water channel 2 47. When there is water in the cavity that needs to be drained, the gravity of the water flow pushes the front blade 451 and rear blade 452 apart, causing elastic deformation, and the water is drained smoothly.

[0040] Emergency overflow and maintenance of main pipeline blockage: Emergency overflow mechanism: If waterway 46 becomes clogged with impurities due to long-term use, rainwater will be unable to drain out and will accumulate in the area between the heat-insulating seal 34 and the rubber diverter 41. When the water level rises to the height of the connecting hole 411 on the rubber diverter 41, the water will overflow through the blocking flanges on both sides of the connecting hole 411 and enter waterway 47 for drainage, preventing water from overflowing the frame and seeping into the room.

[0041] Removable for maintenance: During cleaning and maintenance, simply remove the windproof component 45 from the central housing 43 to flush and unclog the interior of waterway 46 and waterway 47 with water.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
