Description

Technical Field

[0001] The present invention relates to the technical field of doors and windows, and particularly to a drainage structure for sliding doors and windows. Background Art

[0002] Sliding doors and windows are a common type of doors and windows, which are widely used in residences, offices, commercial places, etc. The sliding doors and windows include a fixed frame, a door and window sash slidably installed in the fixed frame, a handle lock installed on the door and window sash, a sliding opening and closing mechanism assembled between the lower end of the door and window sash and the fixed frame, and a linkage mechanism for linking the handle lock and the sliding opening and closing mechanism. By rotating the handle lock, the door and window sash can be raised or lowered, so that the door and window sash is in an unlocked state or a locked state.

[0003] Generally, a drainage structure is also provided on the sliding doors and windows, and the rainwater and the like entering the sliding doors and windows are discharged to the outdoor space through the drainage structure to achieve the purpose of waterproofing. Figure 14 And Figure 15 is a schematic diagram of the drainage structure of the door and window sash in the prior art. As Figure 14 、 15 shown, the existing drainage structure of the sliding doors and windows is as follows: an outdoor drainage path P3 is provided on the lower frame profile 11 of the sliding doors and windows, which is located on the outdoor side of the door and window sash and is used to discharge the rainwater and the like entering the outdoor side part of the lower frame profile 11 to the outdoor space, and an indoor drainage path P4 is located on the indoor side of the door and window sash and is used to discharge the rainwater and the like entering the indoor side part of the lower frame profile 11 to the outdoor space; the outdoor drainage path P3 and the indoor drainage path P4 are independent of each other and are separated by a wind shield 41 provided in the lower frame profile and below the overlapping part of the door and window sash. The rainwater and the like entering the outdoor side part of the lower frame profile 11 are discharged to the outdoor space through a waterproof groove 12 formed between the outer guide rail and the inner guide rail on the lower frame profile and a drainage hole communicating the waterproof groove 12 and the outdoor space (i.e., the outdoor drainage path P3); the rainwater and the like entering the indoor side part of the lower frame profile 11 are discharged to the outdoor space through a waterproof groove 12 formed between the outer guide rail and the inner guide rail on the lower frame profile, an opening part communicating the waterproof groove 12 and the cavity 16 of the lower frame profile, the cavity 16 of the lower frame profile, and a drainage hole communicating the cavity 16 of the lower frame profile and the outdoor space (i.e., the indoor drainage path P4).

[0004] In the drainage structure of the above sliding doors and windows, when the wind pressure on the outdoor side is too large, it will cause a large pressure difference between the wind pressure on the outdoor side and the pressure in the indoor drainage path P4 on the indoor side of the door and window sash. As a result, on the indoor drainage path P4, there may be a problem that rainwater and the like cannot be discharged to the outdoor space and instead backflow into the indoor space; moreover, since rainwater and the like will enter the cavity 16 of the lower frame profile 11 on the indoor drainage path P4, there is also a problem that the rainwater and the like that enter the cavity 16 of the lower frame profile 11 cannot be discharged to the outdoor space and accumulate in the cavity 16 of the lower frame profile 11. Summary of the Invention

[0005] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a drainage structure for sliding doors and windows, which can effectively prevent rainwater and the like from entering the indoor space through the sliding doors and windows, so that the sliding doors and windows have good waterproof performance.

[0006] To achieve the above purpose, the present invention provides a drainage structure for sliding doors and windows. The sliding doors and windows include a fixed frame, a door and window sash slidably installed in the fixed frame, a handle lock installed on the door and window sash, a sliding opening and closing mechanism assembled between the lower end of the door and window sash and the fixed frame, and a linkage mechanism for linking the handle lock and the sliding opening and closing mechanism. By rotating the handle lock, the door and window sash can be raised or lowered, so that the door and window sash is in an unlocked state or a locked state; a waterproof groove is provided on the lower frame profile of the fixed frame, and an elastically deformable spacer is provided in the waterproof groove. The spacer is located below the overlapping part of the door and window sash and divides the waterproof groove into a water accumulation forming part and a drainage part. The drainage part is provided with a drainage hole communicating with the outdoor space; when the door and window sash is in the locked state, the door and window sash presses the spacer, and the spacer elastically deforms, and the water accumulation forming part becomes a water accumulation space. When the door and window sash is in the unlocked state, the door and window sash is away from the spacer, and a gap communicating the water accumulation forming part and the drainage part is formed between the spacer and the waterproof groove.

[0007] Through the drainage structure of the sliding door and window above, when it rains, close the door and window sash and turn the handle lock to lower the door and window sash to the locked state. On the one hand, when the door and window sash descends, it presses the spacer component, causing the spacer component to elastically deform. After elastic deformation, the spacer component blocks the water accumulation forming part, making the water accumulation forming part airtight to form a water accumulation space, and the rainwater entering the water accumulation forming part accumulates in the water accumulation forming part. On the other hand, the rainwater entering the drainage part is discharged to the outdoor space through the drainage holes provided in the drainage part. After the rain stops, turn the handle lock to raise the door and window sash to the unlocked state. At this time, the door and window sash rises away from the spacer component, and the spacer component returns to its initial state before elastic deformation, forming a gap connecting the water accumulation forming part and the drainage part between the spacer component and the waterproof groove. The rainwater accumulated in the water accumulation forming part flows into the drainage part through the above gap and is discharged to the outdoor space through the drainage holes provided in the drainage part. Thus, the drainage structure of the sliding door and window above can effectively prevent rainwater, etc. from entering the indoor space through the sliding door and window, making the sliding door and window have good waterproof performance.

[0008] The preferred solution of the above technical solution is: the spacer component includes a wind baffle and a leaf spring fixed to the lower surface of the wind baffle. In this way, when the door and window sash is in the unlocked state, the door and window sash is away from the spacer component, and the leaf spring is in a bent state without elastic deformation. A gap connecting the water accumulation forming part and the drainage part is formed between the spacer component and the waterproof groove through the bent leaf spring. When the door and window sash is in the locked state, the door and window sash presses the spacer component, the leaf spring elastically deforms and fits with the bottom of the waterproof groove, and the spacer component 40 and the waterproof groove 12 are closely connected, and rainwater, etc. cannot pass through the spacer component.

[0009] The preferred solution of the above technical solution is: the door and window sash includes an outer door and window sash and an inner door and window sash. An outer guide rail and an inner guide rail extending along the length direction of the lower frame profile and used for guiding the outer door and window sash and the inner door and window sash respectively are provided on the lower frame profile. The waterproof groove is located between the outer guide rail and the inner guide rail. The water accumulation forming part is located on the indoor side of the outer door and window sash, and the drainage part is located on the outdoor side of the inner door and window sash. In this way, since the water accumulation forming part is located on the indoor side of the outer door and window sash and the drainage part provided with drainage holes is located on the outdoor side of the inner door and window sash, when the door and window sash is closed and the handle lock is turned to lower the door and window sash to the locked state, the water accumulation forming part is not connected to the drainage part and becomes an airtight water accumulation space. Therefore, even when the wind pressure on the outdoor side is too large, rainwater, etc. will not enter the water accumulation forming part located on the indoor side through the spacer component, and it can effectively prevent the rainwater in the drainage structure from flowing back into the indoor space.

[0010] The preferred solution of the above technical solution is as follows: An installation groove for installing the outer guide rail is formed between the outer side wall of the waterproof groove and the outer side wall of the lower frame profile. The drain holes include a first drain hole provided on the outer side wall of the waterproof groove and a second drain hole provided on the outer side wall of the lower frame profile. The first drain hole communicates the waterproof groove with the installation groove, and the second drain hole communicates the installation groove with the outdoor space. In this way, rainwater and the like entering the drainage part can be discharged to the outdoor space through the first drain hole and the second drain hole.

[0011] The preferred solution of the above technical solution is as follows: The lower frame profile further includes a cavity located below the waterproof groove and extending along the length direction of the lower frame profile. A third drain hole communicating the cavity with the outdoor space is provided on the outer side wall of the cavity, and a first opening part communicating the waterproof groove with the cavity is provided on the bottom surface of the waterproof groove. In this way, rainwater and the like entering the drainage part can not only be discharged to the outdoor space through the first drain hole and the second drain hole, but also enter the cavity through the first opening part and then be discharged to the outdoor space through the third drain hole of the cavity. Therefore, even if a large amount of rainwater and the like enter the drainage part, the rainwater and the like can be discharged to the outdoor space more efficiently through the above structure. In addition, although rainwater and the like are also discharged to the outdoor space through the cavity, since the cavity communicates with the drainage part on the outdoor side of the door and window sash, there is no pressure difference between the inside of the cavity and the outdoor space, and the rainwater and the like entering the cavity can be discharged to the outdoor space through the third drain hole and will not accumulate inside the cavity.

[0012] The preferred solution of the above technical solution is as follows: A second opening part communicating the installation groove with the cavity is provided on the bottom surface of the installation groove. In this way, rainwater and the like entering the installation groove from the first drain hole can not only be discharged to the outdoor space through the second drain hole, but also enter the cavity through the second opening part and then be discharged to the outdoor space through the third drain hole of the cavity. Therefore, the rainwater and the like can be discharged to the outdoor space more efficiently through the above structure.

[0013] The preferred solution of the above technical solution is as follows: The first opening part and the second opening part are communicated. In this way, the rainwater and the like can be discharged to the outdoor space more efficiently.

[0014] The preferred solution of the above technical solution is as follows: A plurality of the first drain holes, the second drain holes and the third drain holes are provided. In this way, the rainwater and the like can be discharged to the outdoor space more efficiently.

[0015] The preferred solution of the above technical solution is as follows: The drainage structure includes a first drainage path composed of a drainage part, an installation groove, a cavity, a first opening part, a second opening part, and a drainage hole, and a second drainage path composed of a water accumulation forming part, a gap, a drainage part, a cavity, a first opening part, and a drainage hole. When it rains, the door and window sash are closed and the handle lock is rotated to lower the door and window sash to a locked state. The rainwater entering the water accumulation forming part accumulates in the water accumulation forming part, and the rainwater entering the drainage part is discharged to the outdoor space through the first drainage path. Specifically, a part of the rainwater entering the drainage part is discharged to the outdoor space through the first drainage hole, the installation groove, and the second drainage hole, and another part of the rainwater enters the cavity through the first opening part, the installation groove, and the second opening part and is discharged to the outdoor space through the third drainage hole. After the rain stops, the handle lock is rotated to raise the door and window sash to an unlocked state, and the rainwater accumulated in the water accumulation forming part is discharged to the outdoor space through the second drainage path. Specifically, the rainwater accumulated in the water accumulation forming part flows into the drainage part through the gap, and then a part of the rainwater is discharged to the outdoor space through the first drainage hole and the second drainage hole, and another part of the rainwater enters the cavity through the first opening part and the second opening part and is discharged to the outdoor space through the third drainage hole. In this way, through the above first drainage path and second drainage path, it is possible to effectively prevent rainwater and the like from entering the indoor space through the sliding door and window, and at the same time ensure that the rainwater and the like entering the sliding door and window can be discharged to the outdoor space without accumulating in the sliding door and window, having a good waterproof effect.

[0016] The preferred solution of the above technical solution is as follows: The wind deflector is made of a foamed airtight material.

[0017] As described above, the drainage structure of the sliding door and window involved in the present invention can effectively prevent rainwater and the like from entering the indoor space through the sliding door and window, and at the same time ensure that the rainwater and the like entering the sliding door and window can be discharged to the outdoor space without accumulating in the sliding door and window, having a good waterproof effect.

[0067] In addition, the descriptions involving "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" can explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0068] The present invention relates to a drainage structure for sliding doors and windows. For the convenience of narration, in the following embodiments, the definitions of each direction are as follows: the width direction of the sliding doors and windows is defined as the left-right direction, the height direction of the sliding doors and windows is defined as the up-down direction, the thickness direction of the sliding doors and windows is defined as the front-back direction, and the front-back direction is also the outdoor-indoor direction. Based on this, Figure 4 In the shown view, the left side and the right side of the paper surface are the left direction and the right direction respectively, the upper side and the lower side of the paper surface are the front direction and the back direction respectively, and the front side and the back side of the paper surface are the up direction and the down direction respectively; and, the front direction is the outdoor side direction, and the back direction is the indoor side direction.

[0069] As Figure 1As shown in the figure, the sliding doors and windows of the present invention include a fixed frame 10, a door and window sash slidably installed in the fixed frame 10, a handle lock 30 installed on the door and window sash, a sliding opening and closing mechanism assembled between the lower end of the door and window sash and the fixed frame 10, and a linkage mechanism for linking the handle lock 30 and the sliding opening and closing mechanism. By rotating the handle lock 30, the door and window sash can be raised or lowered, so that the door and window sash is in an unlocked state or a locked state. Among them, the unlocked state means that the door and window sash can slide in the fixed frame 10, and the locked state means that the door and window sash cannot slide in the fixed frame 10. The fixed frame 10 is fixed at the opening of the building and includes an upper frame profile and a lower frame profile 11 extending left and right, and a left frame profile and a right frame profile extending up and down. The door and window sash includes a sash frame and a sash panel inside the sash frame. The sash frame includes an upper sash frame profile and a lower sash frame profile extending left and right, and a left sash frame profile and a right sash frame profile extending up and down. The sash panel is usually glass. As Figure 1 , Figures 10 to 11 shown, when the sliding doors and windows are closed, the overlapping part of the two door and window sashes is called the overlapping part 23. The above-mentioned sliding doors and windows include two door and window sashes slidably installed in the fixed frame 10. In other embodiments, the above-mentioned sliding doors and windows may also include a door and window sash fixedly installed in the fixed frame 10 and a door and window sash slidably installed in the fixed frame 10.

[0070] As Figures 2 to 7 shown, in the drainage structure of the sliding doors and windows of the present invention, a waterproof groove 12 is provided on the lower frame profile 11 of the fixed frame 10, and an elastically deformable spacer 40 is provided in the waterproof groove 12. The spacer 40 is located below the overlapping part 23 of the door and window sash and divides the waterproof groove 12 into a water accumulation forming part 121 and a drainage part 122. A drainage hole communicating with the outdoor space is provided in the drainage part 122; As Figure 10 , Figure 11 shown, when the door and window sash is in the locked state, the door and window sash presses the spacer 40, and the spacer 40 elastically deforms, and the water accumulation forming part 121 becomes a water accumulation space. When the door and window sash is in the unlocked state, the door and window sash is far away from the spacer 40, and a gap 50 communicating the water accumulation forming part 121 and the drainage part 122 is formed between the spacer 40 and the waterproof groove 12.

[0071] With the drainage structure of the above sliding doors and windows, when it rains, close the door and window sash and turn the handle lock 30 to lower the door and window sash to the locked state. On the one hand, when the door and window sash descends, it presses the spacer member 40, causing the spacer member 40 to elastically deform. After elastic deformation, the spacer member 40 blocks the water accumulation formation part 121, making the water accumulation formation part 121 airtight to form a water accumulation space, and the rainwater entering the water accumulation formation part 121 accumulates in the water accumulation formation part 121. On the other hand, the rainwater entering the drainage part 122 is discharged to the outdoor space through the drainage holes provided in the drainage part 122. After the rain stops, turn the handle lock 30 to raise the door and window sash to the unlocked state. At this time, the door and window sash rises away from the spacer member 40, and the spacer member 40 returns to the state before elastic deformation, forming a gap 50 connecting the water accumulation formation part 121 and the drainage part 122 between the spacer member 40 and the waterproof groove 12. The rainwater accumulated in the water accumulation formation part 121 flows into the drainage part 122 through the gap 50 and is discharged to the outdoor space through the drainage holes provided in the drainage part 122. Thus, the drainage structure of the above sliding doors and windows can effectively prevent rainwater and the like from entering the indoor space through the sliding doors and windows, making the sliding doors and windows have better waterproof performance.

[0072] Further, as Figure 8 , Figure 9 shown, the spacer member 40 includes a wind deflector 41 and a leaf spring 42 fixed to the lower surface of the wind deflector 41. As Figure 11 shown, when the door and window sash is in the unlocked state, the door and window sash is away from the spacer member 40, and the leaf spring 42 is in a bent state without elastic deformation. Through the bent leaf spring 42, a gap 50 connecting the water accumulation formation part 121 and the drainage part 122 is formed between the spacer member 40 and the waterproof groove 12. As Figure 10 shown, when the door and window sash is in the locked state, the door and window sash presses the spacer member 40, the leaf spring 42 elastically deforms and fits with the bottom of the waterproof groove 12, and the spacer member 40 and the waterproof groove 12 are in close contact, and rainwater and the like cannot pass through the spacer member 40.

[0073] Specifically, the wind deflector 41 and the leaf spring 42 have the same projected dimensions in the up-and-down direction and are both rectangular. The lower surface of the wind deflector 41 is a flat surface, and a limiting protrusion 411 is provided on the lower surface of the wind deflector 41. A limiting hole 421 sleeved on the outer periphery of the limiting protrusion 411 is provided on the leaf spring 42. Both the limiting protrusion 411 and the limiting hole 421 are preferably rectangular. The cooperation of the limiting protrusion 411 and the limiting hole 421 can better position and fix the wind deflector 41 and the leaf spring 42. Fixing portions 422 that are attached and fixed to the lower surface of the wind deflector 41 are provided at two corners on one diagonal of the leaf spring 42, and contact portions 423 that are away from the lower surface of the wind deflector 41 and are used to contact the bottom surface of the waterproof groove 12 are provided at two corners on the other diagonal of the leaf spring 42. The fixing portions 422 and the adjacent two contact portions 423 are connected to each other through inclined connecting portions 424. The fixing portions 422 can be fixed to the lower surface of the wind deflector 41 by existing technical means such as bonding, and the wind deflector 41 is preferably made of a foaming airtight material.

[0074] In addition, the spacer member 40 can also be of other structures. For example, the spacer member 40 is made of an elastically deformable foaming airtight material. When the door and window sash is in the unlocked state, the door and window sash is away from the spacer member 40, and a communication groove connecting the water accumulation forming portion 121 and the drainage portion 122 is formed on the bottom surface and / or side surface of the spacer member 40 that contacts the waterproof groove 12, that is, a gap is formed between the spacer member 40 and the waterproof groove 12, and rainwater and the like in the water accumulation forming portion 121 can flow into the drainage portion 122 through the communication groove; when the door and window sash is in the locked state, the door and window sash presses the spacer member 40, the spacer member 40 elastically deforms to seal the communication groove, and the spacer member 40 and the waterproof groove 12 are in close contact, and rainwater and the like cannot pass through the spacer member 40.

[0075] Furthermore, as Figures 1 to 3 shown, the door and window sash includes an outer door and window sash 21 and an inner door and window sash 22. An outer guide rail 13 and an inner guide rail 14 that extend along the length direction of the lower frame profile 11 and are used to guide the outer door and window sash 21 and the inner door and window sash 22 respectively are provided on the lower frame profile 11. In Figure 2 、 Figure 3The outer door and window sash 21, the inner door and window sash 22, the side frame and the upper frame of the fixed frame are omitted. After the sliding door and window are actually assembled, the outer door and window sash 21 is located above the outer guide rail 13, and the inner door and window sash 22 is located above the inner guide rail 14. The waterproof groove 12 is located between the outer guide rail 13 and the inner guide rail 14, the water accumulation forming part 121 is located on the indoor side of the outer door and window sash 21, and the drainage part 122 is located on the outdoor side of the inner door and window sash 22. In this way, since the water accumulation forming portion 121 is located on the indoor side of the outer door and window sash 21, and the drainage portion 122 provided with drainage holes is located on the outdoor side of the inner door and window sash 22, when the door and window sashes are closed and the handle lock 30 is turned to lower the door and window sashes and put them in a locked state, the water accumulation forming portion 121 is not connected to the drainage portion 122 and becomes a closed water accumulation space. Therefore, even when the wind pressure on the outdoor side is too high, rainwater will not enter the water accumulation forming portion 121 located on the indoor side through the partition component 40, which can effectively prevent rainwater in the drainage structure from backflowing into the indoor space.

[0076] Furthermore, if Figure 2 , Figure 3 , Figure 7 As shown, Figure 2 This is a schematic diagram of the drainage structure of the sliding door and window in this application. The figure omits the outer door and window sash, the inner door and window sash, the side frame and the upper frame of the fixed frame. Figure 3 for Figure 2 Schematic diagram of the drainage structure of the sliding door and window from another perspective. Figure 7 for Figure 2 The schematic diagram of the structure after omitting the outer rail and the inner rail. An installation groove 15 for installing the outer rail 13 is formed between the outer wall of the waterproof groove 12 and the outer wall of the lower frame profile 11. The drainage holes include a first drainage hole 123 arranged on the outer wall of the waterproof groove 12 and a second drainage hole 111 arranged on the outer wall of the lower frame profile 11. The first drainage hole 123 connects the waterproof groove 12 and the installation groove 15, and the second drainage hole 111 connects the installation groove 15 and the outdoor space. In this way, rainwater etc. entering the drainage part 122 can be discharged to the outdoor space through the first drainage hole 123 and the second drainage hole 111.

[0077] Furthermore, if Figure 2 , Figures 4 to 6 As shown, Figure 4 This is a top view of the drainage structure of the sliding door and window in this application. The figure omits the outer door and window sash, the inner door and window sash, the side frame and the upper frame of the fixed frame. Figure 5 for Figure 2 AA section view, Figure 6 for Figure 4Cross-sectional view taken along line B-B. The lower frame profile 11 further includes a cavity 16 located below the waterproof groove 12 and extending along the length direction of the lower frame profile 11. A third drain hole 161 communicating the cavity 16 with the outdoor space is provided on the outer side wall of the cavity 16, and a first opening 124 communicating the waterproof groove 12 with the cavity 16 is provided on the bottom surface of the waterproof groove 12. The outer side wall of the cavity 16 is in the same plane as the outer side wall of the lower frame profile 11, that is to say, the outer side wall of the cavity 16 is formed by extending the outer side wall of the lower frame profile 11. In this way, rainwater and the like entering the drainage part 122 can not only be discharged to the outdoor space through the first drain hole 123 and the second drain hole 111, but also enter the cavity 16 through the first opening 124 and then be discharged to the outdoor space through the third drain hole 161 of the cavity 16. Therefore, even if a large amount of rainwater and the like enter the drainage part 122, the rainwater and the like can be discharged to the outdoor space more efficiently through the above structure. In addition, although rainwater and the like are also discharged to the outdoor space through the cavity 16, since the cavity 16 communicates with the drainage part 122 on the outdoor side of the inner door and window sash 22, there is no pressure difference between the inside of the cavity 16 and the outdoor space, and the rainwater and the like entering the cavity 16 can be discharged to the outdoor space through the third drain hole 161 and will not accumulate inside the cavity 16.

[0078] Furthermore, as Figure 7 shown, a second opening 151 communicating the installation groove 15 with the cavity 16 is provided on the bottom surface of the installation groove 15, and preferably the first opening 124 and the second opening 151 are communicated. In this way, rainwater and the like entering the installation groove 15 from the first drain hole 123 can not only be discharged to the outdoor space through the second drain hole 111, but also enter the cavity 16 through the second opening 151 and then be discharged to the outdoor space through the third drain hole 161 of the cavity 16. Therefore, the rainwater and the like can be discharged to the outdoor space more efficiently through the above structure. In addition, it is preferably to provide a plurality of first drain holes 123, second drain holes 111 and third drain holes 161. More preferably, a second drain hole 111 is also opened at a position corresponding to the second opening 151 on the outer side wall of the lower frame profile 11.

[0079] As Figure 12 、 Figure 13As shown in the figure, the drainage structure of the above sliding doors and windows includes a first drainage path P1 and a second drainage path P2. The first drainage path P1 is composed of a drainage part 122, a mounting groove 15, a cavity 16, a first opening 124, a second opening 151 and a drainage hole. The second drainage path P2 is composed of a rainwater accumulation forming part 121, a gap 50, a drainage part 122, a cavity 16, a first opening 124 and a drainage hole. When it rains, the door and window sash is closed and the handle lock 30 is rotated to lower the door and window sash to the locked state. The rainwater entering the rainwater accumulation forming part 121 accumulates in the rainwater accumulation forming part 121. The rainwater entering the drainage part 122 is discharged to the outdoor space through the first drainage path P1. Specifically, a part of the rainwater entering the drainage part 122 is discharged to the outdoor space through the first drainage hole 123, the mounting groove 15 and the second drainage hole 111, and another part of the rainwater enters the cavity 16 through the first opening 124, the mounting groove 15 and the second opening 151 and is discharged to the outdoor space through the third drainage hole 161. After the rain stops, the handle lock 30 is rotated to raise the door and window sash to the unlocked state. The rainwater accumulated in the rainwater accumulation forming part 121 is discharged to the outdoor space through the second drainage path P2. Specifically, the rainwater accumulated in the rainwater accumulation forming part 121 flows into the drainage part 122 through the gap 50, and then a part of the rainwater is discharged to the outdoor space through the first drainage hole 123 and the second drainage hole 111, and another part of the rainwater enters the cavity 16 through the first opening 124 and the second opening 151 and is discharged to the outdoor space through the third drainage hole 161. In this way, through the above first drainage path P1 and second drainage path P2, it is possible to effectively prevent rainwater and the like from entering the indoor space through the sliding doors and windows, and at the same time ensure that the rainwater and the like entering the sliding doors and windows can be discharged to the outdoor space and will not accumulate in the sliding doors and windows, having a good waterproof effect.
