Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, in particular to a drainage structure of a sliding door and window. Background Art

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

[0003] Usually, a drainage structure is also provided on the sliding door and window, and rainwater etc. entering the sliding door and window are discharged to the outdoor space through the drainage structure to achieve the purpose of waterproofing. Fig.14 and Fig.15 Schematic diagram of drainage structure of doors and windows in the prior art. Fig.14 , 15 As shown, the drainage structure of the existing 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 rainwater and the like that enters the outdoor side part of the lower frame profile 11 to the outdoor space; and an indoor drainage path P4 is provided on the indoor side of the door and window sash and is used to discharge rainwater and the like that enters 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 that is provided in the lower frame profile and is located below the overlapping part of the door and window sash. Rainwater and the like that enters the outdoor side portion of the lower frame profile 11 is discharged to the outdoor space via the waterproof groove 12 formed between the outer guide rail and the inner guide rail on the lower frame profile and the drainage hole connecting the waterproof groove 12 and the outdoor space (i.e., the outdoor drainage path P3); rainwater and the like that enters the indoor side portion of the lower frame profile 11 is discharged to the outdoor space via the waterproof groove 12 formed between the outer guide rail and the inner guide rail on the lower frame profile, the opening portion connecting the waterproof groove 12 and the cavity 16 of the lower frame profile, the cavity 16 of the lower frame profile, and the drainage hole connecting 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-mentioned sliding doors and windows, when the outdoor wind pressure is too high, it will cause a large difference in pressure between the outdoor wind pressure and the indoor drainage path P4 located on the indoor side of the door and window fan, so that on the indoor drainage path P4, rainwater and the like may not be able to be discharged to the outdoor space and backflow into the indoor space; and, because 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 rainwater and the like that enters the cavity 16 of the lower frame profile 11 cannot be discharged to the outdoor space and accumulates in the cavity 16 of the lower frame profile 11. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model 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 better waterproof performance.

[0006] To achieve the above-mentioned purpose, the utility model provides a drainage structure of a sliding door and window, the sliding door and window comprising a fixed frame, a door and window leaf slidably mounted on the fixed frame, a handle lock mounted on the door and window leaf, a sliding opening and closing mechanism installed between the lower end of the door and window leaf and the fixed frame, and a linkage mechanism that links the handle lock and the sliding opening and closing mechanism, the door and window leaf can be raised or lowered by rotating the handle lock, so that the door and window leaf is in an unlocked state or a locked state; a waterproof groove is arranged on the lower frame profile of the fixed frame, an elastically deformable spacing component is arranged in the waterproof groove, the spacing component is located below the overlapping portion of the door and window leaf, and divides the waterproof groove into a water accumulation forming portion and a drainage portion, the drainage portion is provided with a drainage hole connected to an outdoor space; when the door and window leaf is in a locked state, the door and window leaf presses the spacing component, the spacing component is elastically deformed, the water accumulation forming portion becomes a water accumulation space, when the door and window leaf is in an unlocked state, the door and window leaf is away from the spacing component, and a gap connecting the water accumulation forming portion and the drainage portion is formed between the spacing component and the waterproof groove.

[0007] Through the drainage structure of the sliding door and window, when it rains, the door and window sash is closed and the handle lock is turned to make the door and window sash descend and enter the locked state. On the one hand, the door and window sash is pressed while descending to make the partition member elastically deform. The elastically deformed partition member blocks the water accumulation forming part, so that the water accumulation forming part is sealed to become 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 hole set in the drainage part. After the rain stops, the handle lock is turned to make the door and window sash rise and enter the unlocked state. At this time, the door and window sash rises and moves away from the partition member, and the partition member returns to the initial state before the elastic deformation. A gap connecting the water accumulation forming part and the drainage part is formed between the partition member and the waterproof groove, and the rainwater accumulated in the water accumulation forming part flows into the drainage part through the gap and is discharged to the outdoor space through the drainage hole set in the drainage part. Therefore, the drainage structure of the sliding door and window can effectively prevent rainwater and the like from entering the indoor space through the sliding door and window, so that the sliding door and window have good waterproof performance.

[0008] The preferred embodiment of the above technical solution is that the spacing member includes a windshield and a leaf spring fixed to the lower surface of the windshield. In this way, when the door and window sash is in an unlocked state, the door and window sash is away from the spacing member, and the leaf spring is in a bent state without elastic deformation. The bent leaf spring forms a gap between the spacing member and the waterproof groove to connect the water accumulation forming part and the drainage part. When the door and window sash is in a locked state, the door and window sash presses the spacing member, the leaf spring elastically deforms and fits with the bottom of the waterproof groove, the spacing member 40 is in close contact with the waterproof groove 12, and rainwater and the like cannot pass through the spacing member.

[0009] The preferred embodiment of the above technical solution is as follows: the door and window sashes include an outer door and window sash and an inner door and window sash, the lower frame profile is provided with an outer guide rail and an inner guide rail extending along the length direction of the lower frame profile for guiding the outer door and window sash and the inner door and window sash respectively, 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 sashes are closed and the handle lock is turned to make the door and window sashes descend and are in a locked state, the water accumulation forming part is not connected with the drainage part and becomes a closed water accumulation space. Therefore, even when the wind pressure on the outdoor side is too large, rainwater and the like will not enter the water accumulation forming part located on the indoor side through the spacing component, which can effectively prevent the rainwater in the drainage structure from backflowing into the indoor space.

[0010] A preferred solution of the above technical solution is: an installation groove for installing the outer rail is formed between the outer side wall of the waterproof groove and the outer side wall of the lower frame profile, the drainage hole includes a first drainage hole arranged on the outer side wall of the waterproof groove and a second drainage hole arranged on the outer side wall of the lower frame profile, the first drainage hole connects the waterproof groove and the installation groove, and the second drainage hole connects the installation groove and the outdoor space. In this way, rainwater etc. entering the drainage part can be discharged to the outdoor space through the first drainage hole and the second drainage hole.

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

[0012] A preferred embodiment of the above technical solution is that the bottom surface of the installation groove is provided with a second opening portion connecting the installation groove and the cavity. In this way, rainwater etc. entering the installation groove from the first drainage hole can not only be discharged to the outdoor space through the second drainage hole, but also can enter the cavity through the second opening portion, and then be discharged to the outdoor space through the third drainage hole of the cavity. Therefore, the above structure can more efficiently discharge rainwater etc. to the outdoor space.

[0013] A preferred embodiment of the above technical solution is that the first opening is connected to the second opening, so that rainwater and the like can be discharged to the outdoor space more efficiently.

[0014] A preferred solution of the above technical solution is that: a plurality of the first drainage hole, the second drainage hole and the third drainage hole are provided, so that rainwater and the like can be more efficiently discharged to the outdoor space.

[0015] The preferred embodiment of the above technical solution is as follows: the drainage structure includes a first drainage path consisting of a drainage portion, a mounting groove, a cavity, a first opening portion, a second opening portion and a drainage hole, and a second drainage path consisting of a water accumulation forming portion, a gap, a drainage portion, a cavity, a first opening portion and a drainage hole. When it rains, the door and window sashes are closed and the handle lock is turned to lower the door and window sashes and lock them. The rainwater entering the water accumulation forming portion is accumulated in the water accumulation forming portion, and the rainwater entering the drainage portion is discharged to the outdoor space through the first drainage path. Specifically, part of the rainwater entering the drainage portion is discharged to the outdoor space through the first drainage hole, the mounting groove and the second drainage hole, and the other part of the rainwater enters the cavity through the first opening portion, the mounting groove and the second opening portion and is discharged to the outdoor space from the third drainage hole. After the rain stops, the handle lock is turned to raise the door and window sashes to the 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 part of the rainwater is discharged to the outdoor space through the first drainage hole and the second drainage hole, and the other part of the rainwater enters the cavity through the first opening and the second opening, and then is discharged to the outdoor space from the third drainage hole. In this way, through the above-mentioned first drainage path and second drainage path, rainwater can be effectively prevented from entering the indoor space through the sliding door and window, and at the same time, it is ensured that the rainwater entering the sliding door and window can be discharged to the outdoor space and will not accumulate in the sliding door and window, which has a good waterproof effect.

[0016] A preferred embodiment of the above technical solution is that the windshield is made of a foamed airtight material.

[0017] As described above, the drainage structure of the sliding doors and windows involved in the utility model can effectively prevent rainwater from entering the indoor space through the sliding doors and windows, while ensuring that rainwater that enters the sliding doors and windows can be discharged to the outdoor space and will not accumulate in the sliding doors and windows, thereby having a good waterproof effect.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0068] The utility model relates to a drainage structure for sliding doors and windows. For the convenience of description, in the following embodiments, the definitions of various directions are as follows: the width direction of the sliding door and window is defined as the left-right direction, the height direction of the sliding door and window is defined as the up-down direction, and the thickness direction of the sliding door and window is defined as the front-back direction, which is also the outdoor and indoor direction. Based on this, Figure 4 In the view shown, the left and right sides of the paper are the left and right directions respectively, the upper and lower sides of the paper are the front and rear directions respectively, the front and back of the paper are the upper and lower directions respectively; and the front direction is the outdoor direction, and the rear direction is the indoor direction.

[0069] like Figure 1As shown, the sliding door and window involved in the utility model includes a fixed frame 10, a door and window leaf slidably mounted on the fixed frame 10, a handle lock 30 mounted on the door and window leaf, a sliding opening and closing mechanism assembled between the lower end of the door and window leaf and the fixed frame 10, and a linkage mechanism that links the handle lock 30 and the sliding opening and closing mechanism. The door and window leaf can be raised or lowered by rotating the handle lock 30, so that the door and window leaf is in an unlocked state or a locked state. Among them, the unlocked state refers to the state in which the door and window leaf can slide in the fixed frame 10, and the locked state refers to the state in which the door and window leaf 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 both extending left and right, and a left frame profile and a right frame profile both extending up and down. The door and window sashes include a sash frame and a sash panel in 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 made of glass. Figure 1 , Figure 10 to Figure 11 As shown, when the sliding door and window are closed, the part where the two door and window sashes overlap each other is called the overlapped part 23. The above sliding door and window comprises two door and window sashes slidably mounted on the fixed frame 10. In other embodiments, the above sliding door and window may also comprise a door and window sash fixedly mounted on the fixed frame 10 and a door and window sash slidably mounted on the fixed frame 10.

[0070] like Figures 2 to 7 As shown, in the drainage structure of the sliding door and window involved in the utility model, a waterproof groove 12 is provided on the lower frame profile 11 of the fixed frame 10, and an elastically deformable spacer component 40 is provided in the waterproof groove 12. The spacer component 40 is located below the overlapping portion 23 of the door and window leaf, and divides the waterproof groove 12 into a water accumulation forming portion 121 and a drainage portion 122. The drainage portion 122 is provided with a drainage hole connected to the outdoor space; Fig.10 , Fig.11 As shown, when the door and window sashes are in a locked state, the door and window sashes press the spacing component 40, the spacing component 40 is elastically deformed, and the water accumulation forming portion 121 becomes a water accumulation space. When the door and window sashes are in an unlocked state, the door and window sashes are away from the spacing component 40, and a gap 50 connecting the water accumulation forming portion 121 and the drainage portion 122 is formed between the spacing component 40 and the waterproof groove 12.

[0071] By means of the drainage structure of the sliding doors and windows, when it rains, the doors and windows are closed and the handle lock 30 is turned to lower the doors and windows and put them in a locked state. On the one hand, the door and window sashes are lowered while pressing the spacer component 40 to elastically deform the spacer component 40. The elastically deformed spacer component 40 blocks the water accumulation forming portion 121, so that the water accumulation forming portion 121 is sealed to become a water accumulation space, and the rainwater entering the water accumulation forming portion 121 is accumulated in the water accumulation forming portion 121; on the other hand, the rainwater entering the drainage portion 122 is discharged to the outdoor space through the drainage holes provided in the drainage portion 122. After the rain stops, the handle lock 30 is turned to raise the door and window sashes to the unlocked state. At this time, the door and window sashes rise and move away from the spacing member 40, and the spacing member 40 returns to the state before the elastic deformation. A gap 50 connecting the water accumulation forming part 121 and the drainage part 122 is formed between the spacing member 40 and the waterproof groove 12. The rainwater accumulated in the water accumulation forming part 121 flows into the drainage part 122 through the gap 50 and is discharged to the outdoor space through the drainage hole provided in the drainage part 122. Therefore, the drainage structure of the sliding door and window can effectively prevent rainwater and the like from entering the indoor space through the sliding door and window, so that the sliding door and window has a good waterproof performance.

[0072] Furthermore, if Figure 8 , Fig. 9 As shown, the spacing member 40 includes a windshield plate 41 and a leaf spring 42 fixed to the lower surface of the windshield plate 41. Fig.11 As shown, when the door and window sash is in the unlocked state, the door and window sash is away from the spacing member 40, and the leaf spring 42 is in a bent state without elastic deformation. The bent leaf spring 42 forms a gap 50 between the spacing member 40 and the waterproof groove 12 to connect the water accumulation forming portion 121 and the drainage portion 122. Fig.10 As shown, when the door and window sashes are in a locked state, the door and window sashes press the spacing component 40, and the leaf spring 42 elastically deforms and fits against the bottom of the waterproof groove 12. The spacing component 40 and the waterproof groove 12 are in close contact, and rainwater cannot pass through the spacing component 40.

[0073] Specifically, the windshield 41 and the leaf spring 42 have the same projection size in the up and down directions, and are both rectangular. The lower surface of the windshield 41 is a plane, and a limiting protrusion 411 is provided on the lower surface of the windshield 41, and a limiting hole 421 is provided on the leaf spring 42, which is sleeved on the outer periphery of the limiting protrusion 411. The limiting protrusion 411 and the limiting hole 421 are preferably rectangular. The windshield 41 and the leaf spring 42 can be better positioned and fixed by the cooperation of the limiting protrusion 411 and the limiting hole 421. The two corners on one diagonal line of the leaf spring 42 are provided with a fixing portion 422 that fits and fixes with the lower surface of the windshield 41, and the two corners on the other diagonal line of the leaf spring 42 are provided with a contact portion 423 that is away from the lower surface of the windshield 41 and is used to contact with the bottom surface of the waterproof groove 12. The fixing portion 422 and the two adjacent contact portions 423 are connected to each other by an inclined connecting portion 424. The fixing portion 422 can be fixed to the lower surface of the windshield plate 41 by conventional means such as bonding, and the windshield plate 41 is preferably made of a foamed airtight material.

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

[0075] Furthermore, if Figures 1 to 3 As shown, the door and window sashes include an outer door and window sash 21 and an inner door and window sash 22. The lower frame profile 11 is provided with an outer guide rail 13 and an inner guide rail 14 extending along the length direction of the lower frame profile 11 for guiding the outer door and window sash 21 and the inner door and window sash 22 respectively. 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 4BB cross-sectional view. The lower frame profile 11 also includes a cavity 16 located below the waterproof groove 12 and extending along the length direction of the lower frame profile 11. The outer wall of the cavity 16 is provided with a third drainage hole 161 connecting the cavity 16 and the outdoor space, and the bottom surface of the waterproof groove 12 is provided with a first opening 124 connecting the waterproof groove 12 and the cavity 16. The outer wall of the cavity 16 and the outer wall of the lower frame profile 11 are located on the same plane, and it can also be said that the outer wall of the cavity 16 is formed by extending the outer wall of the lower frame profile 11. In this way, rainwater etc. entering the drainage portion 122 can not only be discharged to the outdoor space through the first drainage hole 123 and the second drainage hole 111, but also enter the cavity 16 through the first opening 124, and then be discharged to the outdoor space through the third drainage hole 161 of the cavity 16. Therefore, even if a large amount of rainwater etc. enters the drainage portion 122, the rainwater etc. can be more efficiently discharged to the outdoor space 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 is connected to the drainage portion 122 located on the outdoor side of the inner door and window 22, there is no pressure difference between the inside of the cavity 16 and the outdoor space. The rainwater and the like that enter the cavity 16 can be discharged to the outdoor space through the third drainage hole 161 and will not accumulate inside the cavity 16.

[0078] Furthermore, if Figure 7 As shown, the bottom surface of the mounting groove 15 is provided with a second opening portion 151 connecting the mounting groove 15 and the cavity 16, and preferably the first opening portion 124 and the second opening portion 151 are connected. In this way, rainwater etc. entering the mounting groove 15 from the first drainage hole 123 can not only be discharged to the outdoor space through the second drainage hole 111, but also enter the cavity 16 through the second opening portion 151, and then be discharged to the outdoor space through the third drainage hole 161 of the cavity 16. Therefore, the above structure can more efficiently discharge rainwater etc. to the outdoor space. In addition, it is preferred to set a plurality of first drainage holes 123, second drainage holes 111 and third drainage holes 161. More preferably, a second drainage hole 111 is also provided at the position of the outer side wall of the lower frame profile 11 corresponding to the second opening portion 151.

[0079] like Fig.12 , Fig.13As shown, the drainage structure of the above-mentioned sliding door and window includes a first drainage path P1 and a second drainage path P2. The first drainage path P1 is composed of a drainage portion 122, a mounting groove 15, a cavity 16, a first opening portion 124, a second opening portion 151 and a drainage hole. The second drainage path P2 is composed of a water accumulation forming portion 121, a gap 50, a drainage portion 122, a cavity 16, a first opening portion 124 and a drainage hole. When it rains, close the doors and windows and turn the handle lock 30 to lower the doors and windows and put them in a locked state. The rainwater that enters the water accumulation forming portion 121 accumulates in the water accumulation forming portion 121, and the rainwater that enters the drainage portion 122 is discharged to the outdoor space through the first drainage path P1. Specifically, a part of the rainwater that enters the drainage portion 122 is discharged to the outdoor space through the first drainage hole 123, the installation groove 15 and the second drainage hole 111, and the other part of the rainwater enters the cavity 16 through the first opening portion 124, the installation groove 15 and the second opening portion 151, and is discharged to the outdoor space from the third drainage hole 161. After the rain stops, the handle lock 30 is turned to raise the door and window sashes to the unlocked state, and the rainwater accumulated in the water accumulation forming part 121 is discharged to the outdoor space through the second drainage path P2. Specifically, the rainwater accumulated in the water accumulation forming part 121 flows into the drainage part 122 through the gap 50, and then part of the rainwater is discharged to the outdoor space through the first drainage hole 123 and the second drainage hole 111, and the other 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 from the third drainage hole 161. In this way, through the above-mentioned first drainage path P1 and second drainage path P2, rainwater can be effectively prevented from entering the indoor space through the sliding door and window, and at the same time, it is ensured that the rainwater entering the sliding door and window can be discharged to the outdoor space and will not accumulate in the sliding door and window, which has a good waterproof effect.

[0080] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
