Description

Window frame drainage structures

Technical Field

The invention relates to the technical field of doors and windows, in particular to a window frame drainage structure.

Background

As shown in fig. 1: the existing window frame comprises an outer window frame 1 and an inner window frame 2, wherein the outer window frame 1 and the inner window frame 2 are connected through a heat insulation bridge-cut-off 3, so that a good heat insulation effect is achieved, the indoor comfort level is kept, and the purposes of being warm in winter and cool in summer are achieved. The cavity 11 of the existing outer window frame 1 is generally flush with the heat insulation bridge 3, and the upper end and the lower end of the cavity 11 are both in a single-notch structure, namely, the upper part of the cavity is provided with an open single notch 4 which can be connected with other profiles. Because the single notch 4 of being in outdoor outer window frame is easy behind the rain or wash behind the glass window ponding, in order to solve single notch ponding problem, set up wash port 7 at the lateral wall of single notch 4 usually among the prior art, discharge external environment through wash port 7 with ponding. Because current section bar is standard size, and its single notch is nearer apart from outer window frame cavity, when meetting rainwater weather, very easily produces ponding in single notch department and spills over even, can not in time discharge ponding to make the window frame produce a large amount of mud dirt or cause certain corruption to the window frame, and then influence the durable degree of window.

The technical scheme of the invention is as follows: a window frame drainage structure comprises an outer window frame and an inner window frame, wherein the outer window frame and the inner window frame are connected through a heat insulation bridge cut-off; the upper part of the outer window frame is of a double-notch structure and comprises a first notch and a second notch, the first notch is connected with the cavity of the outer window frame, and the second notch is connected with the upper part of the first notch; the outer side wall of the first notch is provided with a drain hole.

Further, the first notch and the second notch are both open structures.

Further, the first notch and the thermal insulation bridge cut-off are arranged in parallel and level.

Further, the second notch with interior window frame parallel and level sets up.

Further, the cross-sectional shape of the first notch is square.

Further, the cross-sectional shape of the second notch is a cone.

Furthermore, the lower part of the cavity of the outer window frame is also of a double-notch structure.

Furthermore, the thermal-insulated bridge cut-off includes two sets of heat insulating strips, and heat insulating strip is connected with the connection face of outer window frame, interior window frame respectively.

Further, the outer window frame is of a square cavity structure.

Further, the drain hole is arranged close to the lower end of the outer side wall of the first notch.

The invention has the beneficial effects that: when ponding rivers are gone into, can not make to form ponding in the cavity of notch, ponding can be smoothly discharged to external environment from the wash port, improves the drainage effect greatly, and improves the durable degree of window frame, and the protection window frame is not corroded or produces the dirt.

Drawings

FIG. 1 is a schematic diagram of a prior art configuration;

fig. 2 is a schematic structural diagram of an embodiment of the present invention.

The attached drawings indicate the following:

1. an outer window frame; 2. an inner window frame; 3. insulating heat and breaking a bridge; 4. a single slot opening; 5. a first notch; 6. a second notch; 7. a drain hole; 11. a cavity; 31. and a heat insulation strip.

Detailed Description

The invention will be described in further detail below with reference to the drawings and specific examples.

As shown in fig. 2: a window frame drainage structure comprises an outer window frame 1 and an inner window frame 2, wherein the outer window frame 1 and the inner window frame 2 are connected through a heat insulation bridge 3; the upper part of the outer window frame 1 is of a double-notch structure and comprises a first notch 5 and a second notch 6, the first notch 5 is connected with a cavity 11 of the outer window frame, and the second notch 6 is connected with the upper part of the first notch 5; the outer side wall of the first notch 5 is provided with a drain hole 7.

The scheme has the following advantages: on the one hand, through changing original single notch structure into two notch structure, can increase the space of notch department for notch department has sufficient space to carry out drainage treatment, and can not produce and spill over, and then avoids the window frame to produce a large amount of mud dirt or causes certain corruption to the window frame.

In this embodiment, the first notch 5 and the second notch 6 are both open structures. In this way, it is possible to drain the other profiles connected to the second notch 6 to the outside environment.

In this embodiment, the first notch 5 is flush with the thermal insulation bridge 3, and the second notch 6 is flush with the inner window frame 1. The original size of the outer window frame is not changed, but the cavity of the outer window frame is made small to increase the height of the notch, namely the existing cavity 11 of the outer window frame is flush with the heat insulation bridge-cut 3, the cavity 11 of the outer window frame is reduced, and the first notch 5 is additionally arranged between the cavity 11 of the outer window frame and the second notch 6, so that enough space is reserved at the notch for draining water, water overflowing and accumulated at the notch cannot be generated, and the drainage performance of the outer window frame 1 is greatly improved. In addition, in order to keep the consistency of the outer window frame structure, the notch at the lower part of the outer window frame cavity is also designed into a double-notch structure which is completely consistent with the double-notch structure at the upper part.

In this embodiment, the drain hole 7 is close to the lower end of the outer side wall of the first notch 5, so that accumulated water can be drained in time.

In this embodiment, the cross-sectional shape of the first notch 5 is square. The cross-sectional shape of the second notch 6 is a cone. The section shape of the single notch of the existing outer window frame is generally conical, and the invention designs the section shape of the additionally arranged first notch 5 into a square notch on the basis of not changing the section shape of the second notch, so that the processing is convenient and the cost is saved.

In this embodiment, thermal-insulated bridge cut-off 3 includes two sets of heat insulating strips 31, and heat insulating strip 31 is connected with the face of being connected of outer window frame 1, interior window frame 2 respectively to realize good thermal-insulated effect, keep indoor comfort level, reach the purpose warm in winter and cool in summer.

In this embodiment, the outer window frame 1 has a square cavity structure. The cavity 11 of the existing outer window frame is generally rectangular, and in the embodiment, by reducing the size of the cavity of the outer window frame, the cavity 11 of the outer window frame is preferably designed to be square.

The working principle of the embodiment is as follows: when the glass window is in rainy weather or cleaned, accumulated water on the outer window frame platform which is easy to accumulate water originally can sequentially pass through the second notch and the first notch on the upper part of the outer window frame cavity and then is discharged through the water discharge hole 7 of the first notch; because there is the drop in the scupper of the uncovered department of second notch and second notch, consequently, when ponding rivers, can not make to form ponding in the cavity of notch, ponding can be smoothly discharged to external environment from the wash port, improves the drainage effect greatly, and improves the durable degree of window frame, and the protection window frame is not corroded or produces the dirt.
