Description

Technical Field

[0001] This invention belongs to the field of door and window technology, specifically a heat-insulating and noise-damping composite door and window structure. Background Technology

[0002] Door and window structures refer to the openings in a building or structure used to enclose the wall, and are collectively referred to as structures that provide functions such as passage, lighting, ventilation, and protection.

[0003] Patent CN206668126U discloses a door and window structure with an externally mounted screen window. The structure includes a rectangular window frame, a screen window frame hinged to the inside of the rectangular window frame, and a screen mesh fixed to the screen window frame. The rectangular window frame has guide rails at its upper and lower ends. The screen window frame is fixed to a slider of the guide rails via an extension connector. The opening and closing of the screen window frame is achieved by the reciprocating movement of the slider. This unique structural design effectively improves the security of the door and window, secures the screen window to its frame, and is aesthetically pleasing while enhancing its anti-pry safety factor.

[0004] However, the above technical solutions still have the following shortcomings in practical applications:

[0005] By installing screens on doors and windows, flying insects such as mosquitoes and flies, as well as larger debris such as willow catkins and fallen leaves, can be prevented from entering the room, without affecting air circulation.

[0006] However, because window screens have multiple ventilation holes, these holes can easily become clogged when impurities adhere to their surface, significantly reducing ventilation. More importantly, these stubborn grime particles, a mixture of insects, catkins, and dust, easily breed bacteria in humid environments, thus polluting the air entering the room. Cleaning window screens often requires complete disassembly, a tedious and laborious process, and frequent disassembly and reassembly can easily cause the screen mesh to deform or the structure to loosen. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, the present invention proposes a heat-insulating and noise-damping composite door and window structure.

[0008] The technical solution adopted by the present invention to solve its technical problem is: a heat-insulating and noise-damping composite door and window structure, including a fixed frame, a window frame rotatably provided on the inner side of the fixed frame, glass provided on the inner side of the window frame, a handle provided on one side of the window frame, and a roll-up self-cleaning dustproof component provided on the fixed frame.

[0009] The self-cleaning dustproof assembly includes a winding shaft rotatably connected to both ends of the inner cavity at the top of the fixed frame. A winding roller is fixedly sleeved on the winding shaft, and a dustproof curtain is wound on the winding roller. The dustproof curtain is made of flexible material and slides through one side of the top of the fixed frame. The dustproof curtain has multiple ventilation holes. A traction plate is fixedly connected to the bottom edge of the dustproof curtain and slides to the side wall of the fixed frame. Sliding rods are fixedly connected to both sides of the inner cavity at the top of the fixed frame. A slider is slidably connected to the sliding rod along the horizontal direction. A brush is provided on one side of the slider. A collection groove is provided on one side of the top of the fixed frame, and the brush is in contact with the surface of the dustproof curtain.

[0010] Preferably, one end of the slider is threadedly connected to a lead screw two, both ends of the lead screw two are rotatably connected to the inner wall of the top of the fixed frame, and a motor three is fixedly connected to one side of the inner cavity of the top of the fixed frame, and the output end of the motor three is fixedly connected to one end of the lead screw two.

[0011] Preferably, guide blocks are fixedly connected to both sides of the inner wall of the top of the fixed frame, and guide rods are slidably passed through the guide blocks. The ends of the two guide rods are fixedly connected to a mounting plate, and two rows of unblocking rods matching the specifications of the vent holes are fixedly connected to one end face of the mounting plate.

[0012] Preferably, an electric actuator is fixedly connected to one side of the inner wall of the top of the fixed frame, and the piston end of the electric actuator is fixedly connected to one side surface of the mounting plate.

[0013] Preferably, a second motor is fixedly connected to one side of the inner cavity at the top of the fixed frame, and the output end of the second motor is fixedly connected to one end of the winding shaft.

[0014] Preferably, one end of the traction plate is threadedly connected to a lead screw, both ends of which are rotatably connected to a fixed frame. A motor is fixedly connected to one side of the fixed frame, and the output end of the motor is fixedly connected to one end of the lead screw.

[0015] Preferably, the fixed frame is provided with a collection auxiliary component;

[0016] The collection auxiliary component includes a spiral conveying rod rotatably connected to both ends of the inner wall of the collection tank. The end of the collection tank is detachably provided with a collection box. One end of the second lead screw is fixedly fitted with a first sprocket, and one end of the spiral conveying rod is fixedly fitted with a second sprocket. The first sprocket and the second sprocket are meshed together with a chain.

[0017] Preferably, the inner end face of the window frame is provided with a sound insulation pad.

[0018] Preferably, the glass surface is covered with a heat-insulating film.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The heat-insulating and noise-damping composite door and window structure of the present invention utilizes a roll-up self-cleaning dustproof component. Whenever the dustproof curtain is rolled up, it can automatically clean the debris on the surface of the dustproof curtain, effectively avoiding the blockage of the ventilation holes caused by the accumulation of impurities and ensuring continuous ventilation. In addition, the entire cleaning process does not require the entire dustproof curtain to be disassembled, fundamentally solving the problems of cumbersome and laborious cleaning of traditional screen windows, and the frequent disassembly and assembly that can easily lead to deformation of the screen mesh or loosening of the structure. This greatly improves the convenience of use, extends the service life of the structure, and also eliminates the safety hazards caused by personnel disassembly and cleaning.

[0021] 2. The heat-insulating and noise-damping composite door and window structure of this invention utilizes a collection auxiliary component. Whenever the second lead screw rotates, the screw conveyor rotates in conjunction with the first and second sprockets and the chain. The rotation of the screw conveyor pushes debris in the collection trough towards the collection box, thus concentrating the debris within the box. Since the collection box is detachable, it can be easily removed and the debris cleaned, thus concentrating the collected debris and facilitating cleaning.

[0022] 3. The heat-insulating and noise-damping composite door and window structure of this invention, by setting a sound-insulating pad on the inner end face of the window frame, when the window frame is closed, the sound-insulating pad fits tightly with the fixed frame, effectively filling the assembly gap between the window frame and the fixed frame, blocking external noise from entering the room through the gap, thereby improving the overall sound insulation performance of the door and window structure. At the same time, the sound-insulating pad also plays a role in buffering and shock absorption, preventing rigid collision between the window frame and the fixed frame when closed.

[0023] 4. The heat-insulating and noise-damping composite door and window structure of the present invention, by attaching a heat-insulating film to the glass surface, can effectively reflect infrared and ultraviolet rays in sunlight, reduce the amount of outdoor heat entering the room in summer, and reduce air conditioning energy consumption; at the same time, the heat-insulating film can also delay the loss of indoor heat to the outside, and play a role in heat preservation in winter.

Detailed Implementation

[0034] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please refer to Figures 1-8 The present invention provides a technical solution: a heat-insulating and noise-damping composite door and window structure, including a fixed frame 1, a window frame 2 rotatably provided on the inner side of the fixed frame 1, a glass 28 provided on the inner side of the window frame 2, a handle 24 provided on one side of the window frame 2, and a roll-up self-cleaning dustproof component provided on the fixed frame 1.

[0036] The self-cleaning dustproof assembly includes a winding shaft 30 rotatably connected to both ends of the top inner cavity of the fixed frame 1. A winding roller 15 is fixedly sleeved on the winding shaft 30. A dustproof curtain 5 is wound on the winding roller 15. The dustproof curtain 5 is made of flexible material and slides through one side of the top of the fixed frame 1. The dustproof curtain 5 has multiple ventilation holes 8. A traction plate 6 is fixedly connected to the bottom edge of the dustproof curtain 5. The traction plate 6 is slidably connected to the side wall of the fixed frame 1. Slide rods 21 are fixedly connected to both sides of the top inner cavity of the fixed frame 1. A slider 7 is slidably connected to the slide rods 21 along the horizontal direction. A brush 9 is provided on one side of the slider 7. A collection groove 11 is provided on one side of the top of the fixed frame 1. The brush 9 is in contact with the surface of the dustproof curtain 5.

[0037] In this embodiment, as Figure 2 , Figure 3 , Figures 5-8 As shown, one end of the slider 7 is threadedly connected to a lead screw 22. Both ends of the lead screw 22 are rotatably connected to the inner wall of the top of the fixed frame 1. A motor 3 27 is fixedly connected to one side of the inner cavity of the top of the fixed frame 1. The output end of the motor 3 27 is fixedly connected to one end of the lead screw 22.

[0038] Guide blocks 29 are fixedly connected to both sides of the top inner wall of the fixed frame 1. Guide rods 13 are slidably passed through the guide blocks 29. The ends of the two guide rods 13 are fixedly connected to the mounting plate 16. Two rows of unblocking rods 17 matching the specifications of the vent holes 8 are fixedly connected to one end face of the mounting plate 16.

[0039] An electric actuator 12 is fixedly connected to one side of the inner wall of the top of the fixed frame 1, and the piston end of the electric actuator 12 is fixedly connected to one side surface of the mounting plate 16.

[0040] A second motor 26 is fixedly connected to one side of the top inner cavity of the fixed frame 1, and the output end of the second motor 26 is fixedly connected to one end of the winding shaft 30.

[0041] One end of the traction plate 6 is threadedly connected to a lead screw 14. Both ends of the lead screw 14 are rotatably connected to the fixed frame 1. A motor 25 is fixedly connected to one side of the fixed frame 1. The output end of the motor 25 is fixedly connected to one end of the lead screw 14.

[0042] Specifically, in existing technologies, door and window structures are usually equipped with screens. Screens can effectively prevent flying insects such as mosquitoes and flies, as well as larger debris such as willow catkins and fallen leaves from entering the room, while not affecting air circulation.

[0043] However, because window screens have multiple ventilation holes, these holes can easily become clogged when impurities adhere to their surface, significantly reducing ventilation. More importantly, these stubborn grime particles, a mixture of insects, catkins, and dust, easily breed bacteria in humid environments, thus polluting the air entering the room. Cleaning window screens often requires complete disassembly, a tedious and laborious process, and frequent disassembly and reassembly can easily cause the screen mesh to deform or the structure to loosen.

[0044] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0045] The fixed frame 1 is installed to the wall, and the window frame 2 is rotated to open and close. When it is necessary to prevent debris from entering the room, motor 26 and motor 25 can be started by an external controller. When motor 26 drives the winding shaft 30 to rotate, the dust curtain 5 wound on the winding roller 15 is unwound. At the same time, when motor 25 drives the lead screw 14 to rotate, the traction plate 6 slides down along the side wall of the fixed frame 1, which can pull the lower end of the dust curtain 5 until the traction plate 6 is in contact with the bottom of the fixed frame 1. The dust curtain 5 can then be used to prevent debris from entering the room.

[0046] When the dust curtain 5 is finished using and is being rolled up, the motor 27 drives the lead screw 22 to rotate, causing the slider 7 to slide laterally back and forth on the slide bar 21. At this time, the brush 9 on the slider 7 will sweep away the debris attached to the surface of the dust curtain 5, and the swept debris will fall into the collection trough 11. Furthermore, the dust curtain 5 is rolled up intermittently. Whenever the dust curtain 5 stops, the two rows of unblocking rods 17 are aligned with the two rows of vent holes 8. The electric push rod 12 can then drive the mounting plate 16 to move laterally, causing the unblocking rods 17 to pass through the vent holes 8, pushing out the impurities attached to the inner wall of the vent holes 8, and causing the impurities to fall into the collection trough 11.

[0047] Repeat the above steps until the dust curtain 5 is completely rolled up. This achieves automatic cleaning of debris on the surface of the dust curtain 5, effectively preventing the air vents 8 from being blocked by accumulated impurities, ensuring continuous ventilation. In addition, the entire cleaning process does not require disassembling the dust curtain 5, fundamentally solving the problems of cumbersome and laborious cleaning of traditional screens, and the frequent disassembly and assembly that can lead to screen deformation or structural loosening. This greatly improves the convenience of use, extends the structural life, and eliminates the safety hazards caused by disassembly and cleaning.

[0048] In this embodiment, as Figure 3 and Figure 4 As shown, a collection auxiliary component is provided on the fixed frame 1;

[0049] The collection auxiliary component includes a spiral conveying rod 10 rotatably connected to both ends of the inner wall of the collection tank 11. A collection box 23 is detachably provided at the end of the collection tank 11. A sprocket 18 is fixedly sleeved at one end of the screw 22. A sprocket 29 is fixedly sleeved at one end of the spiral conveying rod 10. A chain 20 is meshed with the sprocket 18 and the sprocket 29.

[0050] Specifically, in the above embodiments, although the debris on the surface of the dust curtain 5 can be cleaned by the coordinated action of the brush 9 and the unblocking rod 17, and the debris can fall into the collection trough 11, since the collection trough 11 has a certain length, the impurities will be scattered in various places in the collection trough 11, making it difficult to clean the debris in the collection trough 11.

[0051] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0052] Whenever the lead screw 22 rotates, the screw conveyor 10 rotates in conjunction with the sprocket 18, sprocket 19, and chain 20. The rotation of the screw conveyor 10 pushes the debris in the collection trough 11 towards the collection box 23, thus concentrating the debris in the collection box 23. Since the collection box 23 is detachable, it can be easily removed and its contents cleaned, thus concentrating the debris and making cleaning easier.

[0053] In this embodiment, as Figure 2 As shown, a sound insulation pad 4 is provided on the inner end face of the window frame 2.

[0054] Specifically, by installing a sound insulation pad 4 on the inner end face of the window frame 2, when the window frame 2 is closed, the sound insulation pad 4 fits tightly against the fixed frame 1, effectively filling the assembly gap between the window frame 2 and the fixed frame 1, blocking external noise from entering the room through the gap, thereby improving the overall sound insulation performance of the door and window structure. At the same time, the sound insulation pad 4 also plays a role in buffering and shock absorption, preventing the window frame 2 from rigidly colliding with the fixed frame 1 when closed.

[0055] In this embodiment, as Figure 2 As shown, a heat-insulating film 3 is attached to the surface of glass 28.

[0056] Specifically, by attaching a heat insulation film 3 to the surface of the glass 28, the heat insulation film 3 can effectively reflect infrared and ultraviolet rays in sunlight, reduce the amount of outdoor heat entering the room in summer, and reduce air conditioning energy consumption; at the same time, the heat insulation film 3 can also delay the loss of indoor heat to the outside, and play a role in heat preservation in winter.

[0057] Working principle: The fixed frame 1 is installed to the wall, and the window frame 2 is rotated to open and close. When it is necessary to prevent debris from entering the room, the external controller can start motor 26 and motor 25. When motor 26 drives the winding shaft 30 to rotate, it unwinds the dust curtain 5 wound on the winding roller 15. At the same time, when motor 25 drives the lead screw 14 to rotate, the traction plate 6 slides down along the side wall of the fixed frame 1, which can pull the lower end of the dust curtain 5 until the traction plate 6 is in contact with the bottom of the fixed frame 1. The dust curtain 5 can then be used to prevent debris from entering the room.

[0058] When the dust curtain 5 is finished using and is being rolled up, the motor 27 drives the lead screw 22 to rotate, causing the slider 7 to slide laterally back and forth on the slide bar 21. At this time, the brush 9 on the slider 7 will sweep away the debris attached to the surface of the dust curtain 5, and the swept debris will fall into the collection trough 11. Furthermore, the dust curtain 5 is rolled up intermittently. Whenever the dust curtain 5 stops, the two rows of unblocking rods 17 are aligned with the two rows of vent holes 8. The electric push rod 12 can then drive the mounting plate 16 to move laterally, causing the unblocking rods 17 to pass through the vent holes 8, pushing out the impurities attached to the inner wall of the vent holes 8, and causing the impurities to fall into the collection trough 11.

[0059] Repeat the above steps until the dust curtain 5 is completely rolled up. This achieves automatic cleaning of debris on the surface of the dust curtain 5, effectively preventing the air vents 8 from being blocked by accumulated impurities, ensuring continuous ventilation. In addition, the entire cleaning process does not require disassembling the dust curtain 5, fundamentally solving the problems of cumbersome and laborious cleaning of traditional screens, and the frequent disassembly and assembly that can lead to screen deformation or structural loosening. This greatly improves the convenience of use, extends the structural life, and eliminates the safety hazards caused by disassembly and cleaning.

[0060] Whenever the lead screw 22 rotates, the screw conveyor 10 rotates in conjunction with the sprocket 18, sprocket 19, and chain 20. The rotation of the screw conveyor 10 pushes the debris in the collection trough 11 towards the collection box 23, thus concentrating the debris in the collection box 23. Since the collection box 23 is detachable, it can be easily removed and its contents cleaned, thus concentrating the debris and making cleaning easier.

[0061] By installing a sound-insulating pad 4 on the inner end face of the window frame 2, when the window frame 2 is closed, the sound-insulating pad 4 fits tightly against the fixed frame 1, effectively filling the assembly gap between the window frame 2 and the fixed frame 1, blocking external noise from entering the room through the gap, thereby improving the overall sound insulation performance of the door and window structure. At the same time, the sound-insulating pad 4 also plays a role in buffering and shock absorption, preventing the window frame 2 from having a rigid collision with the fixed frame 1 when closed.

[0062] By attaching a heat insulation film 3 to the surface of glass 28, the heat insulation film 3 can effectively reflect infrared and ultraviolet rays in sunlight, reduce the amount of outdoor heat entering the room in summer, and reduce air conditioning energy consumption; at the same time, the heat insulation film 3 can also delay the loss of indoor heat to the outside, and play a role in heat preservation in winter.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
