Referring to fig. 1 to 4, an object of the present embodiment is to disclose a door/window edge sealing structure, which is applied between a first door/window 1 and a second door/window 2 adjacent to the first door/window 1 in a sliding door, wherein the edge sealing structure includes a first choke strip 3, the first choke strip 3 is installed on a side of a frame of the first door/window 1, and the first choke strip 3 extends in a direction of a plane where a side of the frame of the second door/window 2 is located, and does not interfere with movement of the first door/window 1 or the second door/window 2; when the frames of the first door/window 1 and the second door/window 2 correspond to each other, the first choke strip 3 is configured to form a first seal 4 between the end of the first choke strip and the second door/window 2, and the first seal 4 is configured to increase the flow resistance of air flowing through a gap between the first choke strip 3 and the second door/window 2.
The door and window edge sealing structure disclosed in this embodiment is configured with the first flow blocking strip 3 extending in the direction of the plane where the side of the frame of the second door and window 2 is located on the side of the frame of the first door and window 1, so as to play a role in filling the gap between the first door and window 1 and the second door and window 2, so as to achieve the purpose of blocking the air circulation between the first door and window 1 and the second door and window 2, and further achieve the purpose of ensuring the basic sealing, and further, by forming the first sealing part 4 between the end of the first flow blocking strip 3 and the side of the frame corresponding to the second door and window 2, because the first sealing part 4 can increase the flow resistance of the air between the first door and window 1 and the second door and window 2, the air flow resistance increases, the corresponding flow rate will naturally decrease, so that the first sealing part 4 can play a role in decreasing the air circulation rate of the gap between the first flow blocking strip 3 and the second door and window 2, thereby achieving the purpose of increasing the sealing performance between the first door and window 1 and the second door and window 2, and window 3 are beneficial for avoiding the service life of the first flow blocking strip.
In the present embodiment, the side of the frame of the first door/window 1 or the second door/window 2 can be understood as an edge side of the first door/window 1 or the second door/window 2 parallel to the main panel (e.g. glass surface); the edges or the frames of the first door window 1 and the second door window 2 correspond to each other, which can be understood as the position states of the first door window 1 and the second door window 2 which are adjacent to each other after the door is closed or the window is closed, that is, the states when two vertical frames closest to each other in the first door window 1 and the second door window 2 correspond to each other after the door is closed or the window is closed; specifically, the first choke strip 3 is preferably installed on the vertical frame of the first door/window 1.
Preferably, referring to fig. 2, a first groove 31 is formed at an end of the first choke strip 3, and a notch of the first groove 31 faces a plane where a side surface of the frame of the second door/window 2 is located; wherein, when the edges of the first door and window 1 and the second door and window 2 are opposite, the cavity between the first groove 31 and the second door and window 2 is shaped as the first sealing part 4. After the door is closed or the window is closed, because the end part of the first choke strip 3 is provided with the first groove 31, the first groove 31 can play a role of suddenly increasing a partial space between the end part of the first choke strip 3 and the second door window 2 for air to flow, so that the air forms a space structure of 'small gap-large gap-small gap' in a circulation gap between the first choke strip 3 and the second door window 2, namely, the air firstly flows through the narrow space, then enters the large space, and then passes through the small space. Due to the narrow initial space, the small volume of air passing through the first flow blocking strip 3 can be ensured to be small (namely, the volume of air passing through each time is small), the flow rate is small, and the resistance is large, after passing through the narrow space, the small volume of air can enter the first groove 31, due to the effect of the first groove 31 playing the role of the sudden increase space, the circulation space is suddenly increased, so that the small volume of air can be mixed and collided with the air in the first groove 31 to form a mixed flow state, and the effect of reducing the air circulation rate is achieved, after the mixed flow speed reduction effect of the small volume of air passing through the first groove 31, the small volume of air can pass through the first flow blocking strip 3 only after passing through the suddenly narrowed space, obviously, the resistance of the small volume of air can be further increased, so that the effect of increasing the air circulation resistance is achieved, namely, the first flow blocking strip 3 achieves the purpose of increasing the air flow resistance by designing the first groove 31 at the end.
Preferably, referring to fig. 1, the door/window edge sealing structure further includes a second choke strip 5 installed on the second door/window 2, where the second choke strip 5 extends in a direction of a plane where a side of a frame of the first door/window 1 is located, and does not interfere with movement of the first door/window 1 or the second door/window 2; wherein, when the rims of the first door window 1 and the second door window 2 correspond to each other, the second choke strip 5 is configured to form a second seal 6 between the end portion thereof and the first door window 1, and the second seal 6 is configured to increase the flow resistance of the air flowing through the gap between the second choke strip 5 and the first door window 1.
Install the second choked flow strip 5 that extends to the frame side direction of first door and window 1 or to the direction of the removal plane of first door and window 1 through the frame side at second door and window 2 to play the effect of corresponding space between filling first door and window 1 and second door and window 2, and combine first choked flow strip 3 to extend in order to block the effect of air circulation to second door and window 2 direction, first choked flow strip 3 and second choked flow strip 5 combine together and can reach the purpose of the circulation route of zigzag air between first door and window 1 and second door and window 2, with the flow resistance of further increase air, reach the purpose of further promoting basic sealing performance.
And furthermore, the second sealing part 6 is formed between the end part of the second flow blocking strip 5 and the side surface of the frame corresponding to the first door window 1, and because the second sealing part 6 can further increase the flow resistance of the air between the first door window 1 and the second door window 2, the air flow resistance is increased, and the corresponding flow rate is naturally further reduced, so that the second sealing part 6 can play a role in reducing the air circulation rate of the gap between the second flow blocking strip 5 and the first door window 1, thereby achieving the purpose of further improving the sealing performance between the first door window 1 and the second door window 2, and the second flow blocking strip 5 does not interfere with the movement of the first door window 1, thereby achieving the purpose of avoiding the failure of the sealing structure and being beneficial to prolonging the service life of the second flow blocking strip 5.
Preferably, the second choke strip 5 is provided with a second groove 51, and a notch of the second groove 51 faces a plane where the side face of the frame of the first door/window 1 is located; when the edges of the first door window 1 and the second door window 2 are opposite, the cavity between the second groove 51 and one door window 1 is formed as the second sealing part 6. Similarly, after the door is closed or the window is closed, because the end of the second choke strip 5 is provided with the second groove 51, the second groove 51 can play a role of suddenly increasing a partial space between the end of the second choke strip 5 and the first door and window 1 for air to flow, so that the air forms a space structure of 'small gap-large gap-small gap' in the circulation gap between the second choke strip 5 and the first door and window 1, namely, the air firstly flows through the narrow space, then enters the large space, and then passes through the small space again. The initial space is narrow, which can achieve the purpose of ensuring that the volume of the air passing through the second flow blocking strip 5 is small (i.e. the volume of the air passing through each time is small), the flow rate is small, and the resistance is large, after passing through the narrow space, when the small volume of air enters the second groove 51, the second groove 51 plays a role of a sudden increase space, the flow space is suddenly increased, which causes the small volume of air to be mixed and collided with the air in the second groove 51 to form a mixed flow state, thereby playing a role of reducing the air flow rate, and after the mixed flow speed reduction function of the small volume of air passing through the second groove 51, the small volume of air passes through the suddenly narrowed space, and then the second flow blocking strip 5 can pass through the suddenly narrowed space, obviously, the resistance of the small volume of air is further increased, thereby achieving the role of increasing the flow resistance of air, that is, the second flow blocking strip 5 achieves the purpose of increasing the flow resistance of air by designing the second groove 51 at the end.
In some embodiments, when the edges of both the first door window 1 and the second door window 2 correspond, the first spoiler strip 3 and the second spoiler strip 5 are configured to form a third seal 7 therebetween, the third seal 7 communicates the first seal 4 and the second seal 6, and the third seal 7 is configured to be able to lengthen the flow path of air between the first door window 1 and the second door window 2. Because the first choke strip 3 is arranged on the first door and window 1 and extends towards the second door and window 2, and the second choke strip 5 is arranged on the second door and window 2 and extends towards the first door and window 1, the first choke strip 3 and the second choke strip 5 can be combined to play a role in bending an air circulation path, and the third sealing part 7 can be used for prolonging the air circulation path between the first door and window 1 and the second door and window 2, so that the air circulation path between the first door and window 1 and the second door and window 2 can be further bent, the aim of reducing the air flow rate is further fulfilled, and the sealing performance is further improved.
When the edges of the first door window 1 and the second door window 2 correspond to each other, the first choke strip 3 and the second choke strip 5 are arranged in a staggered manner, so that a space between the first choke strip 3 and the second choke strip 5 is formed into a third sealing part 7. During the door closing or window closing process, the first choke strip 3 and the second choke strip 5 are close to each other, so that a space between the two is compressed, that is, during the door closing or window closing process, more specifically, during the process of completing the door closing operation or completing the window closing operation, as shown in fig. 3, the air in the third sealing portion 7 flows outwards due to the close proximity of the first choke strip 3 and the second choke strip 5, that is, after the air in the third sealing portion 7 is compressed, the air flows into the first groove 31 and the second groove 51 through the ports at the two ends thereof, that is, when the first choke strip 3 and the second choke strip 5 are close to each other, the flow direction of the air in the third sealing portion 7 toward the inside of the first groove 31 is opposite to the flow direction of the air outside the first door window 1 flowing into the first groove 31 through the first choke strip 3, and the flow direction of the air in the third sealing portion 7 toward the inside of the second groove 51 is opposite to the flow direction of the air outside the second door window 2 flowing into the inside of the second choke strip 51 through the second choke strip 5. The third sealing portion 7 is located between the first spoiler strip 3 and the second spoiler strip 5, and therefore, obviously, the air flowing into the first groove 31 in the third sealing portion 7 can further block the air flowing from the outside of the first spoiler strip 3, so as to further increase the air flow resistance, and similarly, the air flowing into the second groove 51 in the third sealing portion 7 can further block the air flowing from the outside of the second spoiler strip 5, so as to further increase the air flow resistance, that is, the third sealing portion 7 can further increase the air flow resistance between the first door window 1 and the second door window 2 during the door closing or window closing process, that is, the sealing performance is further improved.
In some embodiments, the first choker bar 3 has a first front end 32 and a first rear end 33; the first front end 32 and the first rear end 33 are both configured to extend in a direction approaching the second door/window 2, and the first rear end 33 is located on one side of the first front end 32 approaching the movement range of the second door/window 2; since the first front end 32 is provided to be able to extend in a direction approaching the second door window 2, this enables the space between the first front end 32 and the second door window 2 to achieve the purpose of being shaped into the first "small gap" structure of "small gap-large gap-small gap"; since the first rear end 33 is disposed to extend in a direction approaching the second door window 2, the space between the first rear end 33 and the second door window 2 can be formed into a second "small gap" structure of "small gap-large gap-small gap".
The wall surface between the first front end 32 and the first rear end 33 is in a circular arc transition to form a first groove 31. As shown in fig. 4, since the wall surface between the first front end 32 and the first rear end 33 is configured to be in the form of an arc transition, after a small amount of air enters the first groove 31 through the first front end 32, the small amount of air will be mixed with the air in the first groove 31 and move along the arc wall surface to form a rotational flow, so that the small amount of air in the rotational flow state can only leave the first flow blocking strip 3 when moving along the wall surface between the second door window or the first groove and passing through the gap between the first rear end 33 and the second door window 2, and the air that cannot move along the wall surface can only continue to move, and therefore, obviously, by configuring the wall surface of the first groove 31 to be in the arc shape, the rotational flow rate can be further reduced, that is, the first groove 31 having the arc wall surface can act to further increase the flow resistance of the air, so as to further improve the sealing performance. Meanwhile, the reverse flow of air in the third sealing portion 7 during the closing or closing of the window also functions to further block the air from flowing out of the first groove 31 from the first rear end 33.
Preferably, the far end of the second choke strip 5 is provided with a second front end 52 and a second rear end 53, the second front end 52 and the second rear end 53 are both configured to be capable of extending in a direction close to the first door window 1, and the second rear end 53 is located on one side of the second front end 53 close to the movement range of the first door window 1; since the second front end 52 is arranged to extend in a direction close to the first door window 1, the space between the second front end 52 and the first door window 1 can be formed into a first "small gap" structure of "small gap-large gap-small gap"; and because the second rear end 53 is arranged to extend towards the direction close to the first door window 1, the space between the second rear end 53 and the first door window 1 can be formed into a second small gap structure in the small gap-large gap-small gap structure.
The wall surface between the second front end 52 and the second rear end 53 is in a circular arc transition to form the second groove 51. Because the wall surface between the second front end 52 and the second rear end 53 is configured to be in the arc transition structure, after a small amount of air enters the second groove 51 through the second front end 52, the small amount of air can be mixed with the air in the second groove 51 and move along the arc wall surface to form a rotational flow, so that the small amount of air in the rotational flow state can only leave the second choked flow bar 5 when moving along the wall surface between the first door window or the second groove and passing through the gap between the second rear end 53 and the first door window 1, and the air which cannot move along the wall surface can only continue to perform the rotational flow movement, and therefore, obviously, by configuring the wall surface of the second groove 51 to be arc-shaped, the effect of further reducing the circulation rate of the air can be achieved, that is, the second groove 51 whose wall surface is arc-shaped can act to further increase the flow resistance of the air, so as to further improve the sealing performance. Likewise, the reverse flow of air in the third sealing portion 7 during the closing or closing of the window also acts as a further barrier to the flow of air out of the second groove 51 from the second rear end 53.
Preferably, when the edges of the first door and window 1 and the second door and window 2 correspond to each other, the gap between the first choke strip 31 and the second door and window 2 is less than or equal to 1mm, so as to achieve the purpose that the first choke strip 31 does not interfere with the movement of the second door and window 2, and/or the gap between the second choke strip 5 and the first door and window 1 is less than or equal to 1mm, so as to achieve the purpose that the second choke strip 5 does not interfere with the movement of the first door and window 1; and/or the gap between the first spoiler strip 3 and the second spoiler strip 5 is less than or equal to 1mm, so that the structural purpose of staggered arrangement between the first spoiler strip 3 and the second spoiler strip 5 is realized, and the gap is small enough to be favorable for improving the reverse flow rate of the air in the third sealing part 7, so as to further increase the flow resistance of the external air flowing into the first groove and the second groove.
Referring to fig. 2 and 3, another object of the present embodiment is to disclose a door and window system, which includes a first door and window 1, a second door and window 2, an outer frame (not shown in the drawings) capable of being embedded in a wall, and the door and window edge sealing structure as described above; the first door window 1 and the second door window 2 are arranged in parallel and are movably arranged on the outer frame body;
