Description

Technical Field

[0001] The present invention relates to the technical field of doors and windows, and more specifically, to a door and window system. Background Art

[0002] Existing outward-opening windows have the advantage of not occupying indoor space when opening outward, so they are favored by users in southern cities and first-tier big cities. Nowadays, most civil buildings are north-south transparent. To meet the needs of lighting and ventilation, the percentage of window area in the building is getting higher and higher. At the same time, due to the rainy weather in the south in summer, rainwater easily enters the interior of the window through the gaps in the door and window profiles, and it is easy for water to accumulate inside the window, soaking the seals and reducing their service life, causing great trouble to users.

[0003] Chinese Utility Model with Publication No. CN215255621 discloses a drainage structure for an outward-opening window, including an installation frame and a sash profile. A mullion is provided on the installation frame. The mullion includes an outer mullion profile and an inner mullion profile. A sash profile is provided on the side of the outer mullion profile away from the installation frame. The sash profile includes an outer sash profile and an inner sash profile. By providing a first water collection cavity on the outer sash profile, a second water collection cavity on the outer mullion profile, and a third water collection cavity on the installation frame, the three water collection cavities cooperate with drainage holes to achieve the drainage work of the inner cavity, and will not backflow to the inner frame profile. At the same time, a floor drain type water outlet cover is added, so that mosquitoes are not easy to enter and the drainage is more rapid and smooth. The inner baffle extending upward from the inner mullion profile effectively blocks rainwater from entering the inner frame profile.

[0004] However, the above-mentioned door and window system uses the method of opening drainage holes on the outer window frame. It does not consider that in windy weather, when the window sash is not closed, there is a situation where rainwater is blown to the inner side of the window sash by the wind and then leaks into the inner side of the window sash. At this time, it is easy for water to accumulate and breed bacteria, and the seals of the doors and windows are soaked for a long time, reducing their service life. Summary of the Invention

[0049] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with its embodiments. It should be understood that the specific implementation modes described herein are only used to explain the present invention and do not limit the protection scope of the present invention.

[0050] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are for the purpose of describing specific embodiments only and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0052] In the present invention, "first" and "second" do not represent specific quantities and orders, but are only used for name distinction.

[0053] As Figure 1 and Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, a door and window system in an embodiment of the present invention includes a window frame 1 and a window sash 2, and an installation gap 101 is provided between the window frame 1 and the window sash 2; the window frame 1 includes an adapter component 10 provided in the inner frame of the window frame 1, and the adapter component 10 includes a first heat insulation unit 11 provided on the upper frame surface, left frame surface and right frame surface of the window frame 1 and a second heat insulation unit 12 provided on the lower frame surface of the window frame 1; a drainage space 102 communicating with the outdoor space is provided at the lower part of the window frame 1; the second heat insulation unit 12 is provided with a drainage channel communicating the installation gap 101 and the drainage space 102.

[0054] By providing a drainage channel communicating the installation gap 101 and the drainage space 102 on the second heat insulation unit 12 in the above-mentioned door and window system, when rainwater enters the inner side of the window sash 2, the rainwater can be discharged from the window sash 2 through the drainage channel of the second heat insulation unit 12, avoiding the situation of water accumulation and bacteria breeding inside the window sash 2.

[0055] As Figure 4 and Figure 10As shown, in one embodiment, the second heat insulation unit 12 includes a blade frame strip 121 and a leaf-shaped rubber strip 122. The blade frame strip 121 is provided with an anti-backflow cavity 120 communicating with the drainage space 102. The anti-backflow cavity 120 is provided with a fastening groove 1211 and a limiting portion 1212. The leaf-shaped rubber strip 122 is provided with a fastening portion 1221 and a blade portion 1222. The leaf-shaped rubber strip 122 is connected to the fastening groove 1211 through the fastening portion 1221, so that the blade portion 1222 can rotate relative to the blade frame strip 121 and realize the switching between the open state and the closed state of the drainage channel. In this way, under the action of wind pressure, the blade portion 1222 is pressed against the limiting portion 1212 in the anti-backflow cavity 120, so that the anti-backflow cavity 120 is divided into multiple closed cavities, thereby realizing the closed state of the drainage channel. When rainwater leaks into the inner cavity of the equal-pressure rubber strip, that is, the installation gap 101, the rainwater can flow downward through the drainage holes opened on the blade frame strip 121 to the anti-backflow cavity 120. When the weight of the rainwater exceeds the wind pressure, the leaf-shaped rubber strip 122 can rotate around the fastening groove 1211, so that the drainage channel is in an open state, and then the rainwater can flow through the anti-backflow cavity 120 and be discharged into the drainage space 102 and then discharged outdoors.

[0056] In one embodiment, the blade portion 1222 includes at least two abutting blades 1223, and the abutting blades 1223 divide the anti-backflow cavity 120 into at least three cavities. In this way, it is convenient for the abutting blades 1223 to abut against the limiting portion 1212 in turn under the action of wind pressure. Through the close contact between the plurality of abutting blades 1223 and the limiting portion 1212, the second heat insulation unit 12 has good airtightness. In addition, when the heat inside and outside the room is exchanged, it passes through multiple cavities, ensuring the heat insulation performance of the second heat insulation unit 12.

[0057] As Figure 5 As shown, in one embodiment, the first heat insulation unit 11 includes a first heat insulation strip 111, and a plurality of heat insulation cavities 1111 are provided inside the first heat insulation strip 111. In this way, each heat insulation cavity 1111 is a small heat insulation unit, and each small heat insulation unit absorbs and attenuates the conducted heat, so as to prevent the aluminum alloy structure window frame 1 from transferring heat through the air and further improve the heat insulation effect.

[0058] As Figure 3As shown, in one embodiment, the first heat insulation strip 111 and the blade frame strip 121 are spliced at a 45-degree angle, and a sealing structure 1112 is provided on the splicing surface of the first heat insulation strip 111. Specifically, the sealing structure 1112 includes sealing with sealant or plugging with a seal. In this way, by setting the sealing structure 1112, it is possible to prevent the airflow of rainwater with wind pressure from entering the first heat insulation units 11 on both sides due to the communication between the anti-backflow cavity 120 of the second heat insulation unit 12 and the first heat insulation strip 111 of the first heat insulation unit 11. After the rainwater converges in the anti-backflow cavity 120, it flows into the drainage space 102 and then is discharged outdoors.

[0059] As Figure 4 and Figure 10 As shown, in one embodiment, a partition rubber strip 21 is provided around the outer frame of the window sash 2. The partition rubber strip 21 is used to abut against the second heat insulation unit 12 to divide the installation gap 101, and the installation gap 101 is divided into a first space 1011 and a second space 1012. Specifically, the drainage space 102 on the window frame 1 communicates with the second space 1012. In this way, when the window sash 2 approaches the window frame 1, by setting the partition rubber strip 21 to press against the second heat insulation unit 12, a sealing structure is formed, so that the liquid cannot backflow into the house from the installation gap 101 between the window sash 2 and the window frame 1, thereby avoiding water seepage of the doors and windows due to rainwater backflow on rainy days.

[0060] As Figure 8 and Figure 9 As shown, in one embodiment, the window sash 2 includes an inner sash frame 203, an outer sash frame 204, and a second heat insulation strip 23. The inner sash frame 203 and the outer sash frame 204 are connected by the second heat insulation strip 23; the second heat insulation strip 23 is provided with a clamping groove, and the partition rubber strip 21 is provided with a first clamping flange adapted to the clamping groove. In this way, by clamping the first clamping flange into the clamping groove, the partition rubber strip 21 is clamped onto the second heat insulation strip 23, thereby realizing detachable connection. Since the partition rubber strip 21 undergoes multiple deformations during the opening and closing process of the window sash 2 and is easily damaged due to fatigue stress, the detachable connection facilitates the replacement of the partition rubber strip 21, thus ensuring the heat insulation effect of the heat insulation structure.

[0061] In one implementation manner, the partition rubber strip 21 is provided with at least two deformation cavities, and the second heat insulation strip 23 is a honeycomb heat insulation strip. In this way, by setting the deformation cavities and the honeycomb heat insulation strip, the heat conduction efficiency of heat is reduced by using the heat attenuation in the cavities, thereby improving the heat insulation effect.

[0062] As Figure 5 and Figure 11As shown, in one embodiment, the door and window system includes a glass assembly 20, and the glass assembly 20 is provided with two glass sides 201 and a glass side end 202; the window sash 2 further includes a sealing strip group 22, and the sealing strip group 22 is provided with a first sealing strip portion 221 and a second sealing strip portion 222. The first sealing strip portion 221 abuts against the glass side end 202, and the second sealing strip portion 222 is sealingly connected to at least one glass side 201. Specifically, the glass assembly 20 includes at least two glass blocks, and the specific structure is glass block, intermediate layer, glass block. Thus, by the close contact between the first sealing strip portion 221 and the second sealing strip portion 222 and the glass assembly 20, at least a double attenuation structure is formed, and by using the second sealing strip portion 222 to be sealingly connected to at least one glass side 201, the airtight performance and watertight performance between the fixed position and the frame of the glass assembly 20 and the window sash 2 are ensured.

[0063] In one embodiment, the sealing connection is glue bonding or / and double-sided tape bonding. Specifically, the sealing connection is bonded along the perimeter of the two glass sides 201. Thus, through the double bonding of glue bonding and double-sided tape bonding, the sealing performance is ensured, and rainwater leakage into the sealing cavity formed between the sealing strip group 22 and the glass assembly 20 is better avoided.

[0064] As Figure 11 shown, in one embodiment, the first sealing strip portion 221 is provided with at least two abutting sealing strips 2211. Thus, the first sealing strip portion 221 abuts against the glass side end 202 to form at least a double attenuation structure, and by using the second sealing strip portion 222 to be sealingly connected to at least one glass side 201, the airtight performance and watertight performance between the fixed position and the frame of the glass assembly 20 and the window sash 2 are ensured.

[0065] As Figure 4 shown, in one embodiment, the window frame 1 includes an inner frame body 103, an outer frame body 104, a third heat insulation strip 13 and a filling unit 14. The adapter assembly 10 and the third heat insulation strip 13 are arranged between the inner frame body 103 and the outer frame body 104; the filling unit 14 includes a filling block 141 and a sealing strip 142; the filling block 141 is arranged below the first heat insulation strip 111, and the sealing strip 142 is clamped in the connection gap between the filling block 141 and the inner frame body 103. Specifically, the adapter assembly 10, the filling unit 14 and the third heat insulation strip 13 are sequentially arranged from top to bottom between the inner frame body 103 and the outer frame body 104. Thus, by arranging the filling unit 14 below the second heat insulation unit 12 in the adapter assembly 10, rainwater seeping into the drainage space 102 is prevented from leaking to the sealing strip 142 between the window frame 1 and the adapter assembly 10 and entering the room, playing a role in attenuating rainwater and the pressure difference; at the same time, the filling unit 14 is used to support the second heat insulation unit 12, thereby avoiding deformation in the anti-backflow cavity 120 due to the long-term accumulation of rainwater, and further ensuring the structural stability.

[0066] In one embodiment, the outer fan frame 204 is provided with a first water flow channel, and a second water flow channel is provided on the outer side of the second heat insulation unit 12 of the adapter component 10 provided on the inner frame body 103 of the window frame 1. Thus, when rainwater leaks from the outer side of the window sash 2, that is, from the outer fan frame 204, the rainwater flows through the first water flow channel, the second space 1012, the second water flow channel, and the drainage space 102 in sequence, thereby realizing the drainage function.

[0067] In one of the embodiments, the adapter component 10 is integrally in a rectangular frame shape. The window frame 1 further includes a connecting piece group 15. The first heat insulation unit 11 is integrally in an inverted U shape, the second heat insulation unit 12 is in a straight shape, and the first heat insulation unit 11 and the second heat insulation unit 12 are spliced at a 45-degree angle, and the connecting piece group 15 is arranged at the splicing position.

[0068] In one embodiment, the connecting piece group 15 includes a first connecting piece 151 and a second connecting piece 152. The first connecting piece 151 is used for inserting and connecting the inner frame body 103 and the inner fan frame 203, and the second connecting piece 152 is used for inserting and connecting the outer frame body 104 and the outer fan frame 204. Specifically, the inner frame body 103, the inner fan frame 203, the outer frame body 104, and the outer fan frame 204 are all aluminum profiles, and the aluminum profiles are provided with corresponding insertion interfaces. Thus, it is convenient for the connecting piece group 15 and the insertion interfaces on the aluminum profiles to play a guiding role in the splicing between the first heat insulation unit 11 and the second heat insulation unit 12 during the insertion process.

[0069] Specifically, both the first connecting piece 151 and the second connecting piece 152 are L-shaped connecting pieces. Thus, the L-shaped connecting piece has a simple structure and is convenient for being inserted into the insertion interfaces on the aluminum profiles.

[0070] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0071] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
