Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of doors and windows, and particularly relates to a door and window drainage structure. BACKGROUND

[0002] As an important part for separating the building from the outside environment, the door and window is usually installed on the installation profile. In daily use, the door and window frequently faces the rainwater invasion. Whenever the rainy weather comes, the rainwater often enters the inside of the door and window through the gap between the door and window and the installation profile. If the rainwater entering the installation profile cannot be discharged outside in time and effectively, the rainwater will accumulate in the door and window frame, which not only can cause the corrosion of the door and window frame due to long-term water accumulation, shorten the service life of the door and window, but also can cause the indoor wall to be damp and moldy, and seriously affect the beauty and comfort of the indoor environment. Therefore, it is very important for the door and window to have a good drainage function.

[0003] Therefore, the prior art opens a drainage hole on the installation profile for discharging the accumulated water. However, this drainage method has many serious problems in actual application. In the strong wind environment, the wind pressure will be greatly increased, and the wind pressure continuously acts on the drainage hole, so that the rainwater entering the installation profile cannot flow out from the drainage hole, and finally the rainwater seeps into the indoor space. More seriously, due to the excessive wind pressure, the rainwater entering the installation profile will also be subjected to a strong reverse force, and flows back into the indoor space, which greatly affects the waterproof performance of the whole window and cannot provide reliable waterproof protection for the indoor space. SUMMARY

[0004] In view of the deficiencies of the prior art, the purpose of the present application is to provide a door and window drainage structure which can realize more convenient drainage.

[0005] The above purpose of the present application is realized by the following technical scheme:

[0006] A door and window drainage structure comprises a connecting profile for installing a door and window, a plurality of water leakage gaps are arranged below the connecting profile, the door and window drainage structure further comprises a bottom profile for connecting with a wall body and a wind baffle connected to the lower end of the bottom profile, the bottom profile is connected to the lower end of the connecting profile, a water storage space is formed in the bottom profile, the water storage space is communicated with the connecting profile through the water leakage gaps, a water outlet gap is arranged below the bottom profile, the water outlet gap is communicated with the water storage space, the water outlet gap is arranged on the outer side of the wall body, and the wind baffle is arranged on the outer side of the water outlet gap.

[0007] According to the further setting of the present application, the lower end of the wind baffle is inwardly bent to form a bent portion.

[0008] The water outlet gap is arranged between the bending part and the wall body.

[0009] The connecting profile is arranged on the inner side of the wall body, and the bottom profile extends to the outside of the wall body.

[0010] The bottom profile comprises a bottom plate forming the bottom of the water storage space, and the bottom plate is arranged to be inclined from high to low in the direction of the wall body.

[0011] The bottom profile further comprises a support rib connected to the bottom of the bottom plate, and the support rib abuts against the upper surface of the wall body.

[0012] The bottom profile further comprises a side plate connected to the bottom of the bottom plate, and the side plate abuts against the outer surface of the wall body, and the water outlet gap is arranged between the side plate and the wind deflector.

[0013] The side plate and the wind deflector have a distance therebetween.

[0014] The water leakage gaps are all arranged on the outer side of the door and window.

[0015] The connecting profile forms a water passing space inside, and the volume of the water passing space is smaller than that of the water storage space.

[0016] In summary, the beneficial technical effects of the present application are:

[0017] 1. The bottom profile of the present application forms a water storage space, which provides a rainwater storage space. When the rainwater is large or there is a temporary obstacle in the drainage process, the water storage space can temporarily store rainwater, prevent rainwater from rapidly accumulating in the connecting profile and possibly overflowing and seeping into the room, play a buffering role, and ensure that the drainage process is more stable and orderly.

[0018] 2. The connecting profile of the present application is provided with a plurality of water leakage gaps below, which can timely guide the rainwater entering the connecting profile into the water storage space of the bottom profile. The water outlet gap is arranged below the bottom profile and communicates with the water storage space, which can make the accumulated water smoothly drain outside. Compared with the traditional way of only arranging a drainage hole on the installation profile, the drainage path is more reasonable, the drainage efficiency is higher, and the accumulation of rainwater in the door and window frame is effectively avoided.

[0019] 3. The bottom profile of the present application is connected with a wind shield at the lower end, and the wind shield is arranged outside the water outlet gap. In a strong wind environment, when wind pressure acts, the wind shield can block the direct influence of wind pressure on the water outlet gap, avoid the situation that rainwater cannot flow out of the drainage hole or even flows back into the room, greatly improve the waterproof performance of the whole window in a strong wind environment, and provide reliable waterproof protection for indoor space.

DETAILED DESCRIPTION

[0022] The present application will be further described in detail below in combination with the drawings.

[0023] As shown in Figure 1 , a door and window drainage structure, comprising a connecting profile 1 for installing a door and window M, a plurality of water leakage gaps 11 arranged below the connecting profile 1, a bottom profile 2 for connecting with a wall Q, and a wind shield 3 connected at the lower end of the bottom profile 2, the bottom profile 2 is connected at the lower end of the connecting profile 1, a water storage space 21 is formed in the bottom profile 2, the water storage space 21 is communicated with the connecting profile 1 through the water leakage gap 11, a water outlet gap 22 is arranged below the bottom profile 2, the water outlet gap 22 is communicated with the water storage space 21, the water outlet gap 22 is arranged outside the wall Q, and the wind shield 3 is arranged outside the water outlet gap 22.

[0024] Specifically, the inner side refers to the side close to the indoor space, and the outer side refers to the side close to the outdoor space, as shown in Figure 1 , the left side in Figure 1 is the outer side, and the right side in Figure 1 is the inner side.

[0025] The water leakage gap 11 of the connecting profile 1 can introduce the rainwater entering the connecting profile 1 into the water storage space 21 of the bottom profile 2 in time, and the water outlet gap 22 can efficiently drain the rainwater in the water storage space 21 to the outdoor. In a strong wind environment, the wind shield 3 can effectively block the effect of wind pressure on the water outlet gap 22, prevent rainwater from not being drained or even flowing back into the room, ensure that the indoor space will not be invaded by rainwater, and greatly improve the waterproof performance of the whole window.

[0026] Further, as shown in Figure 1As shown, the lower end of the baffle 3 is bent inward to form a bent portion 31, and the baffle 3 semi-surrounds the water outlet gap 22, and the baffle 3 forms a shelter on the lower side and the outer side of the water outlet gap 22.

[0027] The bending process of the baffle 3 changes the mechanical structure of the lower end of the baffle 3, so that it can better disperse stress when subjected to external force. Compared with the straight baffle 3, the baffle 3 with the bent portion 31 has significantly improved structural stability when resisting external forces such as wind and rain impact. In the long-term outdoor environment, it can effectively reduce deformation and damage caused by wind and rain, prolong the service life of the baffle 3, and thus ensure the long-term effectiveness of the entire drainage structure.

[0028] The bent portion 31 effectively eliminates the sharp corners that may exist on the edge of the baffle 3. During daily use and door and window M maintenance, whether it is normal window edge activities of residents or inspection and maintenance of door and window drainage structure by maintenance personnel, the risk of being scratched by sharp edges is greatly reduced, providing a safer use environment for users and maintenance personnel.

[0029] When strong winds hit, the bent portion 31 acts as a flow guide device to change and scatter the direction of the wind flow. When the strong wind hits the baffle 3, the bent portion 31 directs part of the wind force to the wall, greatly weakening the direct effect of wind pressure on the water outlet gap 22.

[0030] In a preferred embodiment, the water outlet gap 22 is arranged between the bent portion 31 and the wall Q, that is, the rainwater flowing out of the water outlet gap 22 is directly affected by gravity and does not drip on the bent portion 31.

[0031] Further, the connecting profile 1 is arranged on the inner side of the wall Q, the bottom profile 2 extends to the outside of the wall Q, the water outlet gap 22 is arranged at the bottom of the bottom profile 2, and the water outlet gap 22 is arranged outside the wall Q.

[0032] The bottom profile 2 extends to the outside of the wall Q and the water outlet gap 22 is outside the wall Q, so that the rainwater can be discharged outside the room in the first time and away from the wall Q. The water outlet gap 22 is arranged at the bottom of the bottom profile 2 and outside the wall Q, and the accumulated water can be quickly and smoothly discharged by gravity. When there is a lot of water in the door and window M frame, the drainage structure can empty the accumulated water in a short time.

[0033] Further, the bottom profile 2 includes a bottom plate 23 forming the bottom of the water storage space 21, and the bottom plate 23 is arranged inclined from high to low along the direction towards the outside of the wall Q. Further, the bottom profile 2 further includes a support rib 24 connected to the bottom of the bottom plate 23, and the support rib 24 abuts against the upper surface of the wall Q.

[0034] Referring to Figure 1As shown, the water storage space 21 is triangular, and the supporting rib 24 supports the bottom plate 23 at one end inside the bottom profile 2, thereby forming the bottom plate 23 in an inclined state.

[0035] The base plate 23 is inclined from high to low along the outer side of the wall Q, which can make full use of gravity to allow rainwater in the water storage space 21 to flow quickly and completely to the drainage gap 22 and be discharged outdoors. Compared with a horizontally set base plate 23, this greatly reduces the time that rainwater stays in the water storage space 21, effectively avoiding the growth of bacteria and odors caused by water accumulation, and also reducing the risk of corrosion caused by long-term immersion of the bottom profile 2 by rainwater, thereby extending the service life of the bottom profile 2 and the entire door and window drainage structure.

[0036] The supporting rib 24 is connected to the bottom of the base plate 23 and abuts against the upper surface of the wall Q. It provides support to the base plate 23 from one end inside the bottom profile 2, allowing the base plate 23 to maintain a stable tilted state. The supporting rib 24 distributes the pressure generated by the base plate 23 due to water accumulation and its own weight, enhancing the overall structural stability of the bottom profile 2. Under severe weather conditions such as strong winds and heavy rain, it effectively prevents the base plate 23 from deforming or being damaged due to uneven stress, ensuring the continuous normal operation of the drainage structure.

[0037] The water storage space 21 is triangular, and together with the sloping base plate 23, this design achieves efficient water storage and drainage functions within a limited space. The triangular structure itself has good stability, and compared with other shapes, it can make reasonable use of space to store rainwater without adding too much material. This ensures that the drainage system can still operate in an orderly manner when there is heavy rainfall, and prevents rainwater from overflowing and seeping into the room due to insufficient water storage space 21.

[0038] Furthermore, the bottom profile 2 also includes a side plate 25, which is connected to the bottom of the bottom plate 23. The side plate 25 abuts against the outer surface of the wall Q. The water outlet gap 22 is located between the side plate 25 and the wind baffle 3. Furthermore, there is a distance between the side plate 25 and the wind baffle 3.

[0039] like Figure 1 As shown, the side panel 25 abuts against the outer surface of the wall Q, forming a tight waterproof barrier between the wall Q and the bottom profile 2. This effectively prevents rainwater from seeping into the room through the gap between the bottom profile 2 and the wall Q, further enhancing the waterproof performance of the doors and windows M and greatly protecting the interior walls and furniture from rainwater erosion.

[0040] Furthermore, a water passage space 12 is formed inside the connecting profile 1, and the volume of the water passage space 12 is smaller than that of the water storage space 21.

[0041] The water passing space 12 is formed inside the connecting profile 1, and rainwater can be quickly guided to the water storage space 21 of the bottom profile 2 after entering the door and window M frame body. The large-capacity storage of the water passing space 12 matched with the water storage space 21 can make the drainage process more smooth and efficient.

[0042] Due to the existence of the water passing space 12, the rainwater entering the connecting profile 1 can be quickly transferred to the water storage space 21, reducing the accumulation time of the rainwater in the connecting profile 1. This greatly reduces the risk of corrosion of the connecting profile 1 due to long-term water accumulation, prolongs the service life of the connecting profile 1, and further ensures the stability and reliability of the entire door and window drainage structure.

[0043] The connecting profile 1 is mainly responsible for installing the door and window M and initially guiding the rainwater. The small water passing space 12 can meet its rainwater transmission function without occupying too much space to affect the installation and overall structural strength of the door and window M. The larger water storage space 21 can better cope with the situation of more rainwater, store and buffer rainwater, and ensure that the drainage system can operate stably under different rainfall conditions, realizing a good match between structure design and functional requirements.

[0044] Further, the water leakage gap 11 is provided with a dustproof device 13, and preferably the dustproof device 13 adopts a replaceable dust screen. After clogging, the dustproof device 13 can be selected to be pulled out or replaced.

[0045] The embodiments of the specific embodiment are preferred embodiments of the utility model, and do not limit the protection scope of the utility model. Therefore, equivalent changes made according to the structure, shape and principle of the utility model should be covered within the protection scope of the utility model.
