However, in practical applications, traditional aluminum windows still face some problems: the problems to be overcome, including airtightness and watertightness, Drainage is good and can not effectively resist the problems caused by strong wind pressure, such as spillage, water seepage, etc., such as the general single-cavity _ or the ladder type (four) material, the brain window through f | water but no external drainage structure Because the wind pressure is not considered in the design, the water content (4) is caused by the water in the water collecting area of the window rail ditch and the rainwater splashes and seeps in a short time after the wind and rain increase. In the improved structure, the inscription window drainage structure is the design point of the current window; however, the existing aluminum window is improved, and the concept of anti-blocking or diversion is not adopted, in an attempt to prevent the rain from infiltrating or infiltrating into the guide. After the introduction, it is discharged to the outside; however, because the gap of the mobile window can not completely block the rainwater infiltration caused by the wind pressure, such as the anti-blocking design, the rain will infiltrate into the room through its gap or be strong. The wind pressure is splashed into the room. On the contrary, if the design of the diversion method is adopted, it is necessary to sacrifice the airtightness of the aluminum window at the same time, and the problem of watertightness and airtightness cannot be taken into consideration. At the time, it is easy to block or release most of the accumulated water due to the pressure of the wind pressure, which makes the window rails easy to accumulate water rapidly, and then it is affected by the strong influence and the money is overflowing and seeping. ^力风[In the number of patent pre-existing cases approved by China (Republic of China), there are 3 various designs for aluminum window drainage structures, such as Announcement No. 5 5 3 3 Ο 2, No. M2 * 5 1012 , No. 28917 1 and No. M3 0 3 9 6 9 and other patents, all of which belong to a flat stepped drainage design, mainly using a drain or drainage buffer block embedded in the aluminum window under the horizontal external plate. The drainage hole' is used to pass rainwater accumulated on the window rail groove through the drainer or the drainage buffer block, and the diversion structure is discharged from the drainage hole on the outer rail plate to the outside; thereby designing two to prevent outdoor strong wind from passing through The drain hole is blown directly to splash the water on the ditch into the room. However, the design of the patent case is strong, when the outdoor strong wind is enhanced, the wind pressure will force the drainage hole to be unable to drain, and when the wind pressure continues to increase and is greater than the drainage pressure? 1_The thief will still pass through the butterfly hole and drain On the draining buffer block of the thief, the gap of the ditch is continuous, and in a very short time (10), it accumulates in the Lin ± _ water blow into the water, so that 'therefore, the conventional drain or drain buffer can slow down part of the The wind basket and j, but can not change the shortcomings caused by strong wind blocking drainage, and the wind pressure is too large, causing water seepage in the ditch catchment area.

The wind pressure of the Ufi thief is not a miscellaneous force, so when the gap is blown in, the spleen is connected. /The six-type blade will still form a gap and the water for the instantaneous vortex of the squadron can be put into the room; in addition, when the wind pressure and the water hold the force, the god-shaped leaf # depends on the drainage hole, and the inside of the track Infiltrated into the indoor ditch, the potential amount of water is blown in the patent case, for example, the US invention patent number 5, or as the various types of related--the window on the door, and the horizontal level under the window Or a window design such as a pull type, in which the U support frame is provided with a flow guiding channel, and then penetrates into the room to cause leakage to guide the rainwater through the channel. 2. Dew: The pipe is reversely blown in. , causing stagnant water. , to solve the existing miscellaneous window - there is a drainage problem in the face directly - at the same time _ Lu window needs = and water is difficult to design, the county (four) is the most basic [new content] industry ί ί ΗΓ 1 1 1 景 景 景Insufficient technology, in order to meet the requirements of production and phoenix, this creation provides a pressure-balanced drain pipe with hollow inner aluminum window, ίΐίίΐ Ϊ 乡 乡 乡 乡 乡 乡 乡 乡 乡 乡 乡 乡 乡The rain-seeking, the origin-external-type long-term job-level ί it makes the -m part of the water pressure and the external strong wind pressure to form pressure - force to change and change - the rain produces I balance 'and thus the rain It is effectively discharged to the outside; in addition to the drainage pipe and the chamber entering the indoor side, in addition to ensuring the function of the window airtightness of the window, it is difficult to overcome by the prior art. Blind spot. The main technical feature of the present invention is that the lower horizontal-pressure balanced drain of the inner hollow aluminum window is connected to the lower horizontal hollow chamber _; the drain includes an L-shaped length that can be arranged along the (four) mounting wall The strip tube and the g-long tube can be fixedly mounted on the horizontal block of the !SS. With the above structure, the flow into the lower cross-flow chamber_water is discharged through the drain port on the bottom side of the drain pipe through the pressure balance to prevent the vertical increase of the rainwater flowing through the drain pipe caused by the wind pressure. The depth of water accumulation, combined with the sum of the depth of water infiltrated into the original hollow chamber, increases the overall net water pressure of the aluminum window, because it can withstand the strongest outdoor environment and ensure its airtight and watertight β aluminum window Air tightness. In addition, this creation can also provide a drainage effect on the bottom side of the drain pipe to reduce the wind pressure caused by the reverse flow of the drain hole into the chamber. [Embodiment] This work is discussed here. The direction is an inner hollow window pressure balanced drainage Ϊ 'Ultra private one to use the pressure balance relationship to make the inner hollow aluminum window to achieve balanced drainage structure in order to thoroughly understand the creation, will be detailed in the following description Steps and their composition. Lai, this creation _ line is limited to the special details familiar to those skilled in the art. In other words, well-known components or steps are not described in detail to avoid unnecessary limitation of the present invention. The preferred embodiment of the present invention will be described in detail below, but in addition to this description, the scope of the creation of the singer is not limited, and the scope of the patent is subject to the scope of the following patents. At the same time, as shown in the first figure, the three-dimensional exploded view of the inner hollow window pressure balanced drain pipe (1) is provided for the creation, including a hollow L-shaped long tube that can be installed along the vertical wall surface of the window (χ χ And a fixing seat (12) capable of fixing the long tube (丄1) to an appropriate position under the aluminum window; wherein, one end of the long tube (11) and the hollow portion of the center of the fixing seat (i 2) Slot '(工 21)&' and connect the drain pipe (1) to the aluminum window by means of the fasteners (2) on both sides of the fixed seat (i 2) = hole (1 2 2) Material (3) ^ appropriate position on the outer bottom side (as shown in the second or third figure); as for the other end of the strip s (11), it is vertically downward along the mounting wall surface (4), and a bottom side is provided with a Drainage port (1 1 1), and in order to reduce the wind pressure of the outdoor side strong wind from the drain port (1 1 1), while ensuring the airtightness of the usual aluminum window, this At the position of the drain (1 1 1), a drainage flap (1 1 2 ) with a backstop effect is provided to allow the rainwater in the drain pipe (i) to pass through the drain flap (112). Exhaust, but the outdoor strong wind is affected by the backwater drainage flap (i 1 2 ), which is less likely to penetrate into the drain pipe (1) to slow down the drain pipe '(j) and the lower window (3) hollow cavity The wind pressure resistance of the chamber (31) allows the rainwater to be smoothly guided into the drain pipe (1) for discharge while improving the airtightness of the aluminum window. Secondly, please refer to the second and third figures at the same time, which is a perspective view and a plan view of the actual assembly of the inner hollow aluminum window pressure balance drain. As mentioned above, this creation system fixes the combined drain pipe (1) to the outdoor side bottom side of the horizontal hollow material (3) under the hollow aluminum window, and makes the L-shaped elongated pipe (11) along the wall surface. (4) Vertically extending downward, the two ends of the hollow drain pipe (1) and the lower cross-section (3) hollow chamber (31) are connected to each other, and are pierced through the wall surface (3). And connected to each other, so that the rainwater in the chamber (31) can be discharged through the perforation (32) into the drain pipe (丄); as for the hollow material (3), the cross-section (3) does not limit its type The design of the lower horizontal material (3) is a hollow chamber (3 1) structure, and the rainwater can be introduced into the inner water, and the pressure is used to balance the drainage pipe (1). i is convenient to explain the technical features and advantages of the present creation, the creator proposes a preferred embodiment 'that is, the creation of the pressure balance drain pipe (the former employer in the country (the Republic of China) proposed the first heart of the window The pressure-balanced drainage system is disclosed in the invention patent case - the in-flight multi-cavity and the cross-cutting material (3), please refer to the second and third figures, because of the multi-cavity method disclosed in the previous application of the application. The long distance formed by the horizontal chamber (3 i ) and the wind pressure is reduced by ==, so that the internal and external pressure _ surface _ balance arranging target unit can be verified by actual verification. The role of 'Dharma and watertight and other effects _ more intensive climate requirements for the water, the "Lie 2 pressure (1) outside the sinister window, said 4 (3) on the light position by the depth of the water storage (10), relative To increase the pressure of the purified water, the wind M is more intense to the side of the side, in order to effectively discharge the rainwater accumulated in the chamber (31) and the row 7 S ( 1 ) to the outside, in design, the chamber) and the drainage f* (1) Saki storage water m light body volume pressure, need to be greater than the outside wind _ force, Qiandu Town public car to calculate its net reduction Force (p) large, clean water dust (P) = depth (Η) x density 1) extended vertical drain (1) increased vertical distance), relatively increased the chamber (3 1 And the water pressure (p) of the water storage space of the drainage pipe section, so that it can withstand the monthly b force of the outdoor side wind, and even if the internal accumulation of rainwater is more easily discharged out of the room (4) Principle of the balance of the health force 'mainly From the airtight condition to the depth of the rainwater infiltrated into the rainwater in (d1), combined with the sum of the water depth of the drain pipe (work), the calculation of the pressure against the wind pressure balance, the chamber (―31 ) The inner water and the drain pipe (1) in the deep water mussel - the upper formula (purge water pressure (p) = depth (8) χ J know, its - Susu · can be secret side wind - firm today pressure The balance _ water pressure is 1Gkgf/m2 (1Gm/m χΐ kgfW). In practical application, the vertical water depth of the creation drain (1) is increased by ΐ ΐ ΐ (3) itself can be stored in the depth of water (8) The sum, depending on the needs of the building, can be obtained from (9) - ~ (10) ^ *, etc., so that the water required for the outdoor side wind pressure can be achieved. The pressure value is 2~3Q, which is suspected to be m2. This water pressure can resist the water tightness caused by the strong wind pressure in the natural world. It completely solves the problem of aluminum window drainage, and this principle is applicable to any A window type 'is not limited to the window type exemplified by this creation. _ As for the practical application of the balanced drainage of this creation, please refer to the third figure, if the outdoor side wind pressure (F丄) is greater than When the water is stored and reduced (F 2) in the chamber (3丄) and the drain pipe (work), the rainwater of the guide will continue to accumulate in the whole of the chamber (31) and the drain pipe (i). The water storage space and the pressure on the indoor and external sides are equalized. When the outdoor side wind pressure (F1) and the chamber (3 1 ) and the drain pipe (1) store the water pressure (f 2 ) (ie When the water pressure (P) is equal to the pressure equalization, the vertical water depth (H) of the liquid surface must be maintained at an appropriate vertical height, and the liquid surface is allowed to float vertically, so as not to cause water overflow. When the outdoor side wind pressure (F丄) is less than the stored water pressure (F 2), the rainwater accumulated in the chamber (31) and the drainage officer (1) due to the principle that the fluid flows from the pressure to the low pressure The drain port (1 1) is discharged to the outside through the drain pipe (1). Referring to the first to third figures, the drain port (1i i) of the water pipe (1) is reversely drained in order to reduce the strong wind on the outdoor side. The air pressure of the tube (i) and the chamber (^1), while at the same time ensuring the airtightness of the aluminum window at the same time, this creation is additionally provided with an inverse on the outdoor side of the drain (1i i) of the drain pipe (1). The draining water flap (1 1 2 ), that is, the drain water (1) and the chamber / 3 1), can be discharged in one direction through the drain flap (丄: 2), but outdoor, strong wind Affected by the backwater drainage flap (1 1 2), it is not easy to pass through the drain pipe (1 ^ penetrate into the chamber (-3 1) to slow down the wind pressure resistance of the water tube (丄) and the chamber (3 work), so that The rainwater can be smoothly guided into the chamber (3 jade) and the drain pipe (1), and the airtightness of the aluminum window is improved.
