A drainage guiding groove is formed in the outdoor side of the bottom of a window outer frame, an aluminum alloy drainage groove and at least one drawer type drainage device are embedded in the drainage guiding groove, the aluminum alloy drainage groove is located below a seam between a window sash and the window outer frame, at least one water leak opening is formed in the bottom of the aluminum alloy drainage groove, the first end of each drawer type drainage device is located below the corresponding water leak opening, the second end of each drawer type drainage device extends out of the window outer frame, at least one water outlet is formed in the bottom of the extending end, and the bottom face of each drawer type drainage device is an inclined surface inclining to the outdoor side. According to the drainage system of the solid-wood internal casement door and window, the waterproof components are added and certain technical measures are taken, so that rainwater seeping into the door and window is smoothly drained out of the door and window, and quality and performance of the door and window are not damaged.

Description

The drainage system of solid wood inward opening door and window
Technical field
The present invention is directly involved in solid wood inward opening door and window, particularly a kind of drainage system of being discharged by the water infiltrated in door and window die cavity outside door and window.
Background technology
As the exterior wall door and window of construction exterior wall fencing construction, it is simultaneously in indoor, outside the direct contact chamber of one side.That is, by the surface of outdoor side, it directly will bear outdoor all kinds of natural environments, if some hazardous substancess in blast, heavy rain, sand and dust and air are to corrosion of door-window section bar etc.In the middle of this, infringement the most direct and common is: in the weather of high wind rain, if rainwater infiltrates in window, if at this moment again can not timely and effectively by water ejection door outside window, so a large amount of rainwater will constantly accumulate and finally infiltrate indoor in door and window, thus cause damage to indoor wall decoration and furniture etc.If the material of door and window itself is timber, does not go out if rainwater accumulates in row in window for a long time, so, itself bring fatal infringement by solid wood door and window.
In door and window industry, ORIENTED DOOR AND WINDOW DESIGN teacher cause damage to interior decoration and door and window itself to prevent rainwater from infiltrating in window, and in the design process of window and door system, one removes and all will take " blocking up " and " row " two kinds of technological means to solve to ooze water problem.So-called " blocking up " just refers to: when the design of window and door system, just adopt the profile structure being conducive to preventing rainwater from infiltrating, and between the frame and fan of the outdoor side of door and window, between frame and glass, increase the encapsulant that some prevent rainwater from infiltrating, as Ethylene Propylene Terpolymer sealing joint strip, silicon cave weather proofing sealant, drape over one's shoulders water etc.So-called " row " just refers to: when the design of window and door system, just adopt the profile structure being conducive to successfully being discharged by the rainwater infiltrated in door and window outside door and window, and on section bar, open upper water-out hole artificially, form drainage channel, utilize equivalent pressure cavity, by enter equivalent pressure cavity the smooth discharge side of water outside.
The metal door and window such as plastic-steel door and window or aluminium alloys opens upper water-out hole artificially, because this two profiles material is cavity type structure, and these two kinds of materials itself have very strong water resistance, flow in the drainage channel of water in door and window, also can not cause damage to door and window itself.But, solid wood door and window is just different, the solid wood profile of solid wood door and window is solid construction, woody body is again the material of water resistance extreme difference in fact, therefore, uses the passage of draining if opened a gap on solid wood profile, if do not do some technical process to this breach, so, carry out larger infringement can on the contrary Solid Door curtain heading tape, if will do protective treatment (as the paint process of traditional surface) to the osculum of in solid wood profile will be a thing that impossible complete.So on existing solid wood door and window, all do not take artificial drainage measure, this also just becomes solid wood door and window one like the ditch that cannot go beyond.
Figure 1 shows that the stifled of aluminium alloys inward opening window and drainage measure (left side in Fig. 1 is outside), 1 and 3 is EPDM waterproofing membrane, its effect stops rainwater to penetrate into as few as possible in window, 2 and 4 is artificial drain holes outputed respectively on fan and frame, and its effect is successfully discharged outside window by this outlet by the water (as shown by arrows path) infiltrated in window.
Figure 2 shows that existing common solid wood window inward opening structure (left side in Fig. 2 is outside), it is not by the measure of water to outdoor discharge, just stop a kind of measure in rainwater infiltration window by fluid sealant 5 and EPDM waterproofing membrane 6 and 7, so, under the pressure of high wind rain, rainwater still can inevitably penetrate in window.
The heat-proof quality of solid wood door and window excellence, and natural texture and recyclability, be all subject to liking of people all the time.People under this contradiction liking the infiltration hidden danger now existing with solid wood door and window of solid wood door and window, how to improve the waterproof of wood, the performance such as anticorrosive; How effectively to prevent rainwater from infiltrating in door and window, and can effectively be discharged to outside window by the water penetrated in door and window, this be also the substantial problem that the interior designers studying solid wood door and window of door and window industry want to solve all the time.
In view of the foregoing, and on the basis of the door and window be processed into solid wood overlay film energy-saving profile, invent and be aly specifically designed to inward opening door and window drainage system used, efficiently solve the waterproof of solid wood door and window, drain function, effectively enhance resistance to corrosion and the application life of solid wood door and window.
Summary of the invention
The invention provides a kind of drainage system of solid wood inward opening door and window, overcome the difficulty of prior art, by increasing some water-fast components, and take some technological means, the rainwater infiltrated in door and window is discharged outside door and window glibly, and does not damage a kind of measure of the quality and performance of door and window itself.
The present invention adopts following technical scheme:
