Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window technology, specifically to a KTK vacuum replacement integrated gas door and window. Background Technology
[0002] As an important component of building envelope, doors and windows directly affect building comfort and energy consumption through their thermal insulation, sound insulation, and energy-saving performance. To improve door and window performance, insulated glass doors and windows have been widely used. Traditional insulated glass typically consists of two or more panes of glass spaced a certain distance apart, sealed around the edges with sealant, forming a dry air cavity in the middle. The low thermal conductivity of the air layer provides thermal and sound insulation.
[0003] To further improve performance, inflatable double-glazed windows and doors have emerged in existing technologies. These windows and doors fill the cavity of the double-glazed glass with a functional gas (such as argon or krypton) that has a lower thermal conductivity than air, significantly reducing heat conduction and transfer between the glass panes, thereby achieving superior thermal insulation performance. The double-glazed glass in these inflatable windows and doors is typically assembled, sealed, and inflated in a single process on a factory production line.
[0004] However, existing inflatable door and window technologies have the following significant drawbacks:
[0005] 1. Gas purity and concentration decay issues: After being filled and sealed at the factory, the purity of the gas inside the insulated glass cannot be guaranteed throughout the entire lifespan of the window or door. This leads to an irreversible decrease in its thermal insulation performance, making it impossible to maintain optimal performance over a long period. Furthermore, users or maintenance personnel cannot replenish, replace, or re-vacuum the gas inside the insulated glass without damaging the window or door structure (e.g., by disassembling the glass or breaking the seal). This makes the performance degradation of the window or door an irreversible process, shortening its energy-efficient lifespan.
[0006] 2. Limited functionality: The type of gas filled in at one time is determined when manufacturing insulated glass, and cannot be flexibly changed according to actual needs (such as seasonal changes or high-altitude environments) during use.
[0007] 3. When factories manufacture insulated glass, they usually blow functional gas into the gaps at the edges that are not completely sealed while the insulated glass is being sealed for the last time, or they put the two panes of glass together in an air curtain environment. Neither of these methods can guarantee the concentration of functional gas inside the insulated glass, and the consumption of functional gas is relatively large.
[0008] Therefore, there is an urgent need for a new type of door and window structure that can effectively solve the above problems. Utility Model Content
[0009] The purpose of this invention is to address the shortcomings of existing technologies by providing a KTK (adjustable) vacuum replacement integrated gas door and window. This invention achieves the adjustability and maintainability of the gas within the sealed cavity, allowing for vacuum replacement of the cavity as needed throughout the entire lifespan of the door and window to maintain or restore optimal gas purity and concentration. Furthermore, it allows for flexible replacement of functional gas types and adjustment of functional gas pressure as required, thereby maintaining the high performance of the door and window in a long-term and stable manner and expanding its functionality.
[0010] To solve the above-mentioned technical problems, this utility model provides a KTK vacuum replacement integrated gas door and window, including a first frame, a second frame, and a middle sealing frame arranged in parallel. The first frame and the second frame are connected by a broken bridge. A first limiting frame is provided on the inner side of the first frame, and a second limiting frame is provided on the inner side of the second frame. A first glass and a second glass are respectively provided on opposite sides of the first limiting frame and the second limiting frame. The middle sealing frame, the first glass, and the second glass together form a sealed cavity. An air hole is opened on the middle sealing frame, and an air pipe is connected to the air hole. Vacuum replacement can be performed on the sealed cavity through the air pipe.
[0011] In some embodiments, the middle sealing frame is located between the first limiting frame and the second limiting frame, and the middle sealing frame is sealed and fixedly connected to the first limiting frame and the second limiting frame. The first glass is sealed and fixedly connected to the first limiting frame, and the second glass is sealed and fixedly connected to the second limiting frame.
[0012] In some embodiments, the inner edge of the middle sealing frame is sealed and fixedly connected to the first glass and the second glass.
[0013] In some embodiments, the first limiting frame is detachably connected to the first side frame, or the second limiting frame is detachably connected to the second side frame.
[0014] In some embodiments, the first limiting frame is integrally formed with the first side frame, and the second limiting frame is snapped into the second side frame.
[0015] In some embodiments, a slot is formed on the inner side of the second frame, and the second limiting frame includes a locking strip, a pad strip, and a limiting strip connected in sequence. The locking strip and the limiting strip are perpendicular to the pad strip. The locking strip is engaged in the slot, the pad strip is in close contact with the inner side of the second frame, and the limiting strip is located between the second glass and the middle sealing frame.
[0016] In some embodiments, the second limiting frame includes a plurality of independent second limiting units, which are arranged at uniform intervals.
[0017] In some embodiments, the first limiting frame includes a plurality of independent first limiting units, which are evenly spaced apart.
[0018] In some embodiments, there is no sealing adhesive joint between the middle sealing frame and the first glass at the location where the first limiting unit is not provided, and there is no sealing adhesive joint between the middle sealing frame and the second glass at the location where the second limiting unit is not provided.
[0019] In some embodiments, an adjustment cavity is provided on one or both sides of the sealed cavity, and the adjustment cavity can be vacuum-displaced.
[0020] The beneficial effects of this utility model are as follows:
[0021] 1. This utility model utilizes the inherent characteristics of thermal break door frames to form a hollow zone containing functional gas at the thermal break. Furthermore, by setting multiple hollow zones, the heat insulation, heat preservation, and noise reduction performance can be further improved. In addition, by setting a first limiting frame and a second limiting frame, when the sealed cavity is evacuated, the first limiting frame and the second limiting frame transfer the pressure borne by the first glass and the second glass to the frame, avoiding the pressure of the glass on the middle sealing frame and ensuring the sealing performance of the sealed cavity.
[0022] 2. After the structure is assembled, this utility model can be vacuum-replaced at any time through the air vents. Users or manufacturers can repeatedly vacuum, refill, or replace the gas in the sealed cavity according to their needs throughout the entire life cycle of the doors and windows. This completely solves the problem of irreversible performance degradation caused by the decay of gas purity in traditional inflatable doors and windows, ensuring that the heat insulation and sound insulation performance is maintained at the best state for a long time. The appropriate gas type can be flexibly selected according to seasonal changes, regional environment (such as high-altitude low-pressure environment) or special energy-saving needs, expanding the intelligent application scenarios and environmental adaptability of doors and windows.
[0023] 3. In existing technologies, insulated glass and aluminum frames are usually manufactured in two separate factories, and then assembled together. However, the doors and windows of this invention are integrated with the frame, meaning that the frame and glass need to be manufactured and assembled in the same factory. Vacuum replacement is then performed after assembly to form a vacuum door and window. The manufacturing, assembly, sealing, and vacuum replacement of the key airtight structures (limiting frame, sealing frame, glass, and frame) are integrated under one responsible entity (the same factory). This results in tighter process connections, reduced interface errors, improved dimensional accuracy, and facilitated monitoring of sealing quality and gas parameters throughout the process. It also reduces the coordination complexity and quality fluctuation risks caused by multiple suppliers and completely avoids the risks of physical damage and stress interference caused by transportation and secondary assembly.
[0024] 4. This utility model can ensure the concentration of functional gas in the sealed cavity between the first glass and the second glass, overcoming the defect of low gas concentration in traditional insulated glass, maximizing the heat insulation performance of functional gas, and reducing the consumption of functional gas.
[0025] 5. During the vacuuming process of the sealed cavity, the glass is deformed by atmospheric pressure, which also tests the glass's compressive strength. In other words, the wind pressure resistance of the glass is tested during the vacuuming process. Moreover, the sealed cavity can only be vacuum-replaced when its airtightness and watertightness are good. Therefore, the airtightness and watertightness of the sealed cavity are also tested. Thus, through vacuum replacement, the wind pressure resistance of the glass and the airtightness and watertightness of the sealed cavity can be tested simultaneously.
[0026] 6. This utility model can be modified to add or remove different configurations according to different functional requirements to meet functional needs. For example, multiple limiting frames can be used to snap together with the frame to form an independently adjustable cavity inside the frame. This can further improve the heat insulation and temperature insulation performance of the integrated gas door and window, and also give the door and window additional performance expansion space beyond basic gas heat insulation, thus enhancing the product's flexibility.
[0027] 7. The pressure seat of this utility model can be installed at different positions on the frame, which significantly improves the compatibility with different glass thicknesses and cavity configurations. Attached Figure Description

Detailed Implementation
[0040] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0041] like Figure 1 As shown, this utility model is illustrated using a casement window as an example. The casement window includes an outer frame 21 and a window sash inside the outer frame 21.
[0042] like Figure 2 As shown, the window sash adopts KTK (adjustable) vacuum replacement integrated gas door and window. The window sash includes a first frame 1 and a second frame 2. The first frame 1 and the second frame 2 can be made of door and window frame material (such as hollow square aluminum tube). A thermal break is set between the first frame 1 and the second frame 2. The first frame 1 and the second frame 2 are fixedly connected by the thermal break.
[0043] like Figure 2 As shown, a first limiting frame 3, a first glass 10, and a pressure seat 14 are provided on the inner side of the first frame 1 (i.e., within the area enclosed by the first frame 1). The first limiting frame 3 is integrally formed with the first frame 1. The first limiting frame 3 can also be fixed to the first frame 1 by welding or bolts after the first frame 1 is manufactured. The first glass 10 is located between the first limiting frame 3 and the pressure seat 14. Adhesive is provided between the first glass 10, the first limiting frame 3, and the first frame 1. That is, the first glass 10 is fixed to the first limiting frame 3 and the first frame 1 by glass glue or structural glue. A pressure line 15 is provided on the pressure seat 14 on the inner side of the first frame 1. The pressure line 15 is snapped into the pressure seat 14. One side of the pressure line 15 is pressed tightly onto the first glass 10 by an adhesive strip.
[0044] like Figure 3 As shown, a second limiting frame 4, a second glass 11, and a pressure seat 14 are provided on the inner side of the second frame 2 (i.e., within the area enclosed by the second frame 2). A slot is opened on the inner side of the second frame 2, and the second limiting frame 4 is engaged with the second frame 2 through the slot. The slot can restrict the translation and rotation of the second limiting frame 4. The second glass 11 is located between the second limiting frame 4 and the pressure seat 14 on the inner side of the second limiting frame 4. The second glass 11 is fixedly connected to the second limiting frame 4 and the second frame 2 using glass glue or structural glue.
[0045] The second limiting frame 4 includes a retaining strip 41, a pad strip 42, and a limiting strip 43 connected in sequence. The retaining strip 41, the pad strip 42, and the limiting strip 43 are integrally formed or connected by welding. The retaining strip 41 and the limiting strip 43 are perpendicular to the pad strip 42. The retaining strip 41 is engaged in a slot, and the pad strip 42 is tightly attached to the inner side of the second frame 2. The second glass 11 is fixedly connected to the limiting strip 43 and the pad strip 42 using glass glue or structural adhesive. A pressure line 15 is provided on the pressure seat 14 on the inner side of the second frame 2. The pressure line 15 is engaged with the pressure seat 14, and one side of the pressure line 15 is tightly pressed onto the second glass 11 by an adhesive strip.
[0046] like Figure 2 As shown, a middle sealing frame 7 is provided between the first limiting frame 3 and the second limiting frame 4. The middle sealing frame 7 is fixedly connected to the first limiting frame 3 and the second limiting frame 4 using glass glue or structural adhesive. Figure 3 As shown, the inner dimensions of the middle sealing frame 7 are smaller than the inner dimensions of the first limiting frame 3 and the second limiting frame 4, so that the inner edge of the middle sealing frame 7 and the first glass 10 and the second glass 11 can be fixedly connected by glass glue or structural glue, thereby ensuring the sealing performance of the sealing cavity and the integrity of the structure.
[0047] Of course, the middle sealing frame 7 can also be sealed and bonded only to the first limiting frame 3 and the second limiting frame 4, or only to the first glass 10 and the second glass 11, but the sealing performance of these two methods cannot be guaranteed.
[0048] It should be noted that the first limiting frame 3 can also adopt the same structural form as the second limiting frame 4, that is, it can be snapped into the first frame 1.
[0049] Optionally, the second limiting frame 4 can adopt the same integral frame structure as the second border 2, or it can adopt multiple independent strip limiting structures, i.e., as shown in the figure. Figure 4 As shown, the second limiting frame 4 includes multiple independent second limiting units. Glass glue or structural adhesive is applied between adjacent second limiting units. That is, the space between the second glass 11 and the middle sealing frame 7 is filled with glass glue or structural adhesive. Two, three, four, or more second limiting units can be provided. Figure 4The diagram illustrates the setting of five second limiting units, meaning that the top of the second limiting frame 4 is composed of five second limiting units. This reduces material usage and lowers the weight and cost of the doors and windows. Furthermore, the first limiting frame 3 can also employ multiple independent strip-shaped limiting structures.
[0050] In addition, the second limiting frame 4 can also be fixedly connected to the second frame 2 by bolts. For example, the second limiting frame 4 only includes a limiting strip 43 and a pad strip 42. A countersunk plate is opened on the pad strip 42, and a threaded hole is opened in the countersunk plate. The second frame 2 has a corresponding threaded hole, and the pad strip 42 can be fixed on the second frame 2 by bolts.
[0051] The first limiting frame 3 and the second limiting frame 4 mentioned above are made of the same material as the first frame 1 and the second frame 2, such as aluminum; the middle sealing frame 7 can be made of organic (such as rubber) or inorganic (such as aluminum) materials. When made of metal, the middle sealing frame 7 can be designed as follows: Figure 2 The structure shown has a U-shaped cross-section, which reduces the amount of material used. The cross-section of the middle sealing frame 7 can also be rectangular.
[0052] like Figure 7 , 8 As shown, an air hole 18 is opened on the middle sealing frame 7, and an air pipe 19 is connected to the air hole 18. The air pipe 19 is a flexible tube, and one end of the air pipe 19 passes through the first frame 1 and is connected to an air nozzle 20. The air nozzle 20 is fixed to the first frame 1. Figure 7 , 8 The diagram illustrates the arrangement of air vents 18 in a casement window. Sliding windows can also use the same arrangement. For fixed sashes, air nozzles 20 can be installed on the interior side of the mullion or frame.
[0053] Understandably, since a sealed cavity is formed between the central sealing frame 7, the first glass 10, and the second glass 11, this sealed cavity can be evacuated and filled with functional gas through the air nozzle 20. During the evacuation process, the first glass 10 and the second glass 11 are subjected to atmospheric pressure. Because the first limiting frame 3 and the second limiting frame 4 respectively restrict the first glass 10 and the second glass 11, the first glass 10 and the second glass 11 will transfer the force to the first limiting frame 3 and the second limiting frame 4, preventing the central sealing frame 7 from being squeezed by the two glass panes and ensuring the sealing performance of the cavity. The device for vacuum replacement of the sealed cavity can be the single-nozzle insulated glass offline filling and evacuation device disclosed in Chinese Utility Model Patent No. CN204387688U.
[0054] Meanwhile, since the KTK vacuum-replacement integrated gas-filled doors and windows undergo vacuum replacement only after all structures are installed, vacuum replacement can be performed at any time. Users or manufacturers can repeatedly vacuum, refill, or replace the gas in the sealed cavity according to their needs throughout the entire life cycle of the doors and windows. This completely solves the problem of irreversible performance degradation caused by the decay of gas purity in traditional gas-filled doors and windows, ensuring that the heat insulation and sound insulation performance remains stable and optimal for a long time. The appropriate gas type can be flexibly selected according to seasonal changes, regional environment, or special energy-saving needs, expanding the intelligent application scenarios and environmental adaptability of doors and windows. For example, in high-altitude and low-pressure environments, conventional insulated glass cannot adjust its internal air pressure and may bulge, while the gas pressure in the sealed cavity of this utility model can be adjusted on-site or vacuum-replaced on-site.
[0055] In addition, this utility model utilizes the inherent characteristics of thermal break door frames to form a hollow zone (i.e., a sealed cavity) containing functional gas at the thermal break point. Furthermore, by setting multiple hollow zones, the heat insulation, heat preservation, and noise reduction performance can be further improved.
[0056] The above is the basic structure of the KTK vacuum-displacement integrated gas door and window. Other structures can be added to this structure, for example... Figure 10 As shown, conventional insulated glass can be directly bonded to the side of the first glass 10 or the second glass 11 away from the central sealing frame 7 using glass glue. A heat insulation strip 23 is set between the second glass 11 and the insulated glass, and the insulated glass is pressed together using the pressure line 15, or more sealing cavities can be set.
[0057] like Figure 5 The diagram illustrates the addition of an adjustment cavity 22 on the side near the second glass 11. Three slots are formed on the inner side of the second frame 2. A third limiting frame 5 is engaged in the second slot, and a fourth limiting frame 6 is engaged in the third slot. The third limiting frame 5 is fixedly connected to the second glass 11 and the second limiting frame 4 using glass glue or structural adhesive. A right sealing frame 9 is provided between the third limiting frame 5 and the fourth limiting frame 6. The third glass 12 is fixedly glued to the fourth limiting frame 6. The right sealing frame 9 is sealed to the third limiting frame 5, the fourth limiting frame 6, the second glass 11, and the third glass 12, forming a sealed adjustment cavity 22 between the right sealing frame 9, the second glass 11, and the third glass 12. Similarly, an air hole 18 can be formed on the right sealing frame 9 and connected to an air pipe 19. The air pipe 19 on the right sealing frame 9 passes through the second frame 2 and connects to an air nozzle 20 on the second frame 2.
[0058] like Figure 6 The diagram illustrates the case where adjustment cavities 22 are added to both sides, and... Figure 5The adjustment cavity 22 in the middle has the same structure. The first frame 1 has two slots, in which the fifth limiting frame 16 and the sixth limiting frame 17 are respectively engaged. The fifth limiting frame 16 is fixedly connected to the first glass 10 by glass glue or structural glue. A left sealing frame 8 is set between the fifth limiting frame 16 and the sixth limiting frame 17. The fourth glass 13 is fixedly glued to the sixth limiting frame 17. The left sealing frame 8 is sealed and glued to the fifth limiting frame 16, the sixth limiting frame 17, the first glass 10, and the fourth glass 13, so that the left sealing frame 8, the first glass 10, and the fourth glass 13 form a sealed adjustment cavity 22. Similarly, an air hole 18 can be opened on the left sealing frame 8 and connected to an air pipe 19. The air pipe 19 on the left sealing frame 8 passes through the first frame 1 and is connected to the air nozzle 20 on the first frame 1.
[0059] To accommodate the addition of other insulated glass units or the adjustment cavity 22, the position of the pressure seat 14 in this invention is adjustable, such as... Figure 9 As shown, taking the first frame 1 as an example, multiple mounting holes are provided on the first frame 1. Nuts corresponding to the mounting holes are welded to the inner side of the first frame 1. The pressure seat 14 can be fixed to different mounting holes by bolts, thereby adjusting the position of the pressure seat 14. In addition, a slotted hole can be provided on the first frame 1, and multiple bolts can be installed in the slotted hole. The bolts can slide along the length of the slotted hole, and the pressure seat 14 can be fixed to the first frame 1 by nuts. Furthermore, the position of the pressure seat 14 can be fixed, and by changing the pressure wire 15 of different sizes, it can also adapt to the addition of other insulated glass or the adjustment cavity 22.
[0060] Figures 2 to 10 The structural shapes shown are for illustrative purposes only; the specific structural style should be designed according to requirements. Figure 11 A schematic diagram of a product created for the applicant, showing its specific dimensions but not the glass.
[0061] In this invention, molecular sieves are placed between two adjacent glass panes.
[0062] The manufacturing method of this KTK vacuum displacement integrated gas door and window includes:
[0063] S1. Seal and glue the first glass 10 onto the first frame 1 and the first limiting frame 3;
[0064] Step S1 specifically includes:
[0065] After the frame (including the first frame 1, the second frame 2, and the break bridge between them), glass, and second limiting frame 4 are manufactured, silicone sealant is applied to the inside of the first frame 1 and one side of the first limiting frame 3 to hold the first glass 10 in place. Figure 2 The left side of the first glass 10 is installed onto the first limiting frame 3, so that the first glass 10 is fixed onto the first frame 1 and the first limiting frame 3 by glass glue.
[0066] S2. Place the middle sealing frame 7 between the first frame 1 and the second frame 2, and seal and glue the middle sealing frame 7 to the first glass 10 and the first limiting frame 3.
[0067] Step S2 specifically includes:
[0068] Apply silicone sealant to the first limiting frame 3 and the first glass 10. Place the middle sealing frame 7 inside the second frame 2 and push the middle sealing frame 7 towards the first frame 1 until the middle sealing frame 7 is tightly attached to the first limiting frame 3, so that the middle sealing frame 7 is sealed and fixedly connected to the first limiting frame 3 and the first glass 10 by silicone sealant.
[0069] It should be noted that the first limiting frame 3 of this utility model can be staggered with the side of the first frame 1 closest to the second frame 2, that is, the first limiting frame 3 is staggered towards the middle of the first frame 1, so that a right angle positioning angle is formed between the first limiting frame 3 and the first frame 1. When the middle sealing frame 7 is pushed in, the right angle positioning angle can position the middle sealing frame 7.
[0070] S3. Snap the second limiting frame 4 to the second frame 2, and seal the second limiting frame 4 to the middle sealing frame 7 with adhesive.
[0071] Step S3 specifically includes:
[0072] Apply silicone sealant to the side of the middle sealing frame 7 away from the first glass 10, and insert the second limiting frame 4 into the slot of the second frame 2, so that the second limiting frame 4 and the middle sealing frame 7 are fixedly connected by silicone sealant.
[0073] S4. Install the second glass 11 on the second limiting frame 4, and seal the second glass 11 with the second limiting frame 4 and the middle sealing frame 7.
[0074] Step S4 specifically includes:
[0075] Apply silicone sealant to the side of the middle sealing frame 7 away from the first glass 10 and to the pads 42 and limiting strips 43 of the second limiting frame 4. If the second limiting frame 4 includes multiple independent second limiting units, silicone sealant should also be applied between two adjacent second limiting units. Install the second glass 11 onto the second limiting frame 4 so that the second glass 11 is sealed and bonded to the second limiting frame 4 and the middle sealing frame 7.
[0076] S5. If it is necessary to set up the adjustment cavity 22, then follow the steps of S3 and S4 to install the corresponding limit frame and glass of the adjustment cavity 22.
[0077] S6. Vacuum replacement of the sealed cavity.
[0078] Step S5 specifically includes:
[0079] Use the nozzle 20 to extract the gas from the sealed cavity and inject a functional gas (such as helium) into the sealed cavity.
[0080] The above operation can be performed once or multiple times. When performing the above operation only once, the sealed cavity can be evacuated to the standard value at one time, and then the functional gas can be filled into the sealed cavity and the gas nozzle can be closed. When performing the above operation multiple times, the sealed cavity can be evacuated to a value lower than the standard value, and then the functional gas can be filled into the sealed cavity. Then the sealed cavity can be evacuated to a value lower than the standard value again, and the functional gas can be filled into the sealed cavity again. After several cycles, the concentration requirements of the functional gas in the sealed cavity can be met.
[0081] If an adjustment chamber 22 is provided, the same method can be used to perform vacuum replacement on the adjustment chamber 22.
[0082] The KTK vacuum-displacement integrated gas doors and windows can also be used in building envelope thermal insulation systems, such as sunroofs and glass curtain walls.
