Description

Technical Field

[0001] The present invention relates to the technical field of doors and windows, and in particular to a KTK vacuum replacement integrated gas door and window and a manufacturing method thereof. Background Art

[0002] Doors and windows are essential components of the building envelope. Their thermal, acoustic, and energy-saving performance directly impacts a building's comfort and energy consumption. To improve their performance, insulating glass doors and windows have become widely used. Traditional insulating glass typically consists of two or more panes of glass spaced a certain distance apart, sealed with sealant on all sides. This creates a dry air cavity in the middle, utilizing the low thermal conductivity of this air layer to provide insulation and soundproofing.

[0003] To further enhance performance, gas-filled insulating glass windows and doors have emerged. These windows and doors employ a functional gas (such as argon or krypton) with a lower thermal conductivity than air, filling the cavity of the insulating glass. This significantly reduces heat conduction and transfer between the panes, resulting in superior thermal insulation. These insulating glass windows and doors typically undergo a single, integrated process of glass assembly, sealing, and gas filling on a factory production line.

[0004] However, existing inflatable door and window technologies have the following significant disadvantages: 1. Gas purity and concentration decay: After a one-time inflation and sealing at the factory, the purity of the gas within the insulating glass cannot be guaranteed throughout the lifecycle of the door or window. This irreversibly degrades the thermal insulation performance and prevents it from maintaining optimal performance over the long term. Furthermore, users or maintenance personnel cannot replenish, replace, or re-evacuate the gas within the insulating glass without damaging the door or window structure (e.g., removing the glass or breaking the seal). This irreversible degradation of the performance of the door or window shortens its energy-efficient lifespan.

[0005] 2. Single functionality: The type of gas filled once is determined when the insulating glass is manufactured, and cannot be flexibly changed according to actual needs (such as seasonal changes, plateau environment) during use.

[0006] 3. When factories produce inflatable insulating glass, they usually blow functional gas into the edge gaps that are not completely closed while the insulating glass is being sealed for the last time, or they put two pieces of glass together under an air curtain environment. The above methods cannot guarantee the concentration of functional gas in the insulating glass, and the consumption of functional gas is relatively high.

[0007] Therefore, there is an urgent need for a new door and window structure that can effectively solve the above problems. Summary of the Invention

[0008] The purpose of the present invention is to address the defects of the existing technology and provide a KTK (i.e., adjustable) vacuum replacement integrated gas door and window and a manufacturing method, which realizes the controllability and maintainability of the gas in the sealed cavity, allowing the cavity to be vacuum replaced as needed throughout the life cycle of the door and window to maintain or restore the optimal gas purity and concentration, and even flexibly replace the type of functional gas and adjust the pressure of the functional gas according to needs, thereby maintaining the high performance of the door and window in a long-term and stable manner and expanding its functionality.

[0009] In order to solve the above technical problems, on the one hand, the present invention provides a KTK vacuum replacement integrated gas door and window, comprising a first frame and a second frame arranged in parallel, the first frame and the second frame being connected by a broken bridge, a first limit frame being arranged on the inner side of the first frame, and a second limit frame being arranged on the inner side of the second frame, the first limit frame and the first frame being detachably connected, and / or the second limit frame and the second frame being detachably connected, a middle sealing frame being arranged between the first limit frame and the second limit frame, a first glass and a second glass being respectively arranged on the side of the first limit frame and the second limit frame away from the middle sealing frame, the middle sealing frame, the first glass and the second glass together form a sealed cavity, an air hole being opened on the middle sealing frame, an air hole being connected to an air pipe, and the sealed cavity can be vacuum replaced through the air pipe.

[0010] In some embodiments, the first limiting frame is integrally formed with the first frame, and the second limiting frame is snap-connected with the second frame.

[0011] Furthermore, a slot is provided on the inner side of the second frame, one end of the second limiting frame cooperates with the slot, and the other end of the second limiting frame is used to limit the second glass.

[0012] Furthermore, the second limiting frame includes a card strip, a pad strip and a limiting strip connected in sequence, the card strip and the limiting strip are perpendicular to the pad strip, the card strip is stuck in the card slot, the pad strip is tightly attached to the inner side of the second frame, and the limiting strip is located between the second glass and the middle sealing frame.

[0013] Furthermore, the second glass is sealed and glued to the gasket strip and the limiting strip.

[0014] In some embodiments, the middle sealing frame is sealed and glued to the first limiting frame, the second limiting frame, the first glass, and the second glass.

[0015] In some embodiments, the second limiting frame includes a plurality of independent second limiting units, and the plurality of second limiting units are evenly spaced.

[0016] In some embodiments, an adjustment cavity is provided on one side or both sides of the sealed cavity, and the adjustment cavity can be vacuum replaced.

[0017] Furthermore, a pressure seat is provided on the inner side of the first frame and the second frame, a pressure line is provided on the pressure seat, and multiple installation positions are provided on the first frame and / or the second frame. The pressure seat is installed at different installation positions according to the glass thickness and the number of adjustment cavities.

[0018] On the other hand, a method for manufacturing a KTK vacuum replacement integrated gas door and window comprises: Sealing the first glass onto the first frame and the first limiting frame; Place the middle sealing frame between the first frame and the second frame, and seal the middle sealing frame with the first glass and the first limiting frame; Clamp the second limiting frame to the second frame, and seal the second limiting frame to the middle sealing frame; Install the second glass on the second limiting frame, and seal the second glass with the second limiting frame and the middle sealing frame; Perform vacuum replacement on the sealed cavity.

[0019] Furthermore, the method for vacuum replacement of the sealed cavity includes: The gas in the sealed cavity is extracted, and functional gas is injected into the sealed cavity; the above operation is performed once or multiple times.

[0020] The beneficial effects of the present invention are: 1. The present invention utilizes the inherent characteristics of the thermal break door frame to form a hollow belt containing functional gas at the thermal break. Moreover, by providing multiple hollow belts, the thermal insulation, heat preservation and noise reduction performance can be further improved. In addition, by providing the first limiting frame and the second limiting frame, when the sealed cavity is vacuumed, the first limiting frame and the second limiting frame transfer the pressure borne by the first glass and the second glass to the frame, thereby avoiding the pressure of the glass on the middle sealing frame and ensuring the sealing of the sealed cavity.

[0021] 2. After the structural assembly of the present invention is completed, vacuum replacement can be performed at any time through the air holes. Users or manufacturers can repeatedly vacuum, inflate or replace the gas in the sealed cavity as needed throughout the life cycle of the doors and windows. This completely solves the problem of irreversible performance degradation of traditional inflatable doors and windows due to the attenuation of gas purity, ensuring that the thermal insulation and sound insulation performance are maintained in the best state for a long time. The appropriate gas type can be flexibly selected according to seasonal changes, regional environment (such as low-pressure environment in the plateau) or special energy-saving needs, thereby expanding the intelligent application scenarios and environmental adaptability of doors and windows.

[0022] 3. In the prior art, the insulating glass and aluminum frames are usually produced by two factories respectively, and then the insulating glass and aluminum frames are assembled. The doors and windows of the present invention are frame-glass integrated doors and windows, that is, the frames and glass need to be produced and assembled in the same factory. After the assembly is completed, vacuum replacement is performed to form vacuum doors and windows. The manufacturing, assembly, sealing and vacuum replacement of key airtight structures (limiting frame, sealing frame, glass, frame) are integrated under one responsible entity (same factory). The process connection is tighter, the interface error is reduced, the dimensional matching accuracy is improved, and the sealing quality and gas parameters are monitored conveniently throughout the process. It also reduces the coordination complexity and quality fluctuation risk caused by multiple suppliers, and completely avoids the physical damage and stress interference risks caused by transportation and secondary assembly.

[0023] 4. The present invention can ensure the functional gas concentration in the sealed cavity between the first glass and the second glass, overcoming the defect of low gas concentration in traditional insulating glass, maximizing the thermal insulation performance of the functional gas, and reducing the functional gas consumption.

[0024] 5. In the process of vacuuming the sealed cavity of the present invention, the glass will be squeezed and deformed by the action of atmospheric pressure. In this process, the compressive resistance of the glass is also tested, that is, the wind pressure resistance of the glass is tested during the vacuuming process. Moreover, the vacuum replacement can only be completed when the airtightness and watertightness of the sealed cavity are good. Therefore, it is also a test of the airtightness and watertightness of the sealed cavity. Therefore, through vacuum replacement, the wind pressure resistance of the glass and the airtightness and watertightness of the sealed cavity can be tested at the same time.

[0025] 6. The present invention can add or subtract different configurations according to different functional requirements to meet functional needs, that is, multiple limit frames can be used to snap into the frame to form an independently adjustable adjustment cavity on the inner side of the frame, which can further improve the heat insulation and temperature insulation performance of the integrated gas doors and windows, and also provide doors and windows with additional performance expansion space in addition to basic gas insulation, thereby improving the flexibility of the product.

[0026] 7. The pressure seat of the present invention can be installed at different positions of the frame, which significantly improves the compatibility with different glass thicknesses and cavity configurations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0030] like Figure 1 As shown, the present invention is described by taking a casement window as an example. The casement window includes an outer frame 21 and a window sash inside the outer frame 21 .

[0031] like Figure 2 As shown, the window sash adopts KTK (i.e. adjustable) vacuum replacement integrated gas door and window, and 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 materials (such as hollow square aluminum tubes). A thermal break bridge is set between the first frame 1 and the second frame 2, and the first frame 1 and the second frame 2 are fixedly connected by the thermal break bridge.

[0032] like Figure 2As 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 range enclosed by the first frame 1). The first limiting frame 3 and the first frame 1 are integrally formed. 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. Glue 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 clamped with the pressure seat 14, and one side of the pressure line 15 is pressed tightly against the first glass 10 by a glue strip.

[0033] 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 range enclosed by the second frame 2). A card slot is provided on the inner side of the second frame 2, and the second limiting frame 4 is clamped to the second frame 2 through the card slot. The card slot can limit 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 by using glass glue or structural glue.

[0034] The second limiting frame 4 includes a clamping strip 41, a padding strip 42, and a limiting strip 43 connected in sequence. The clamping strip 41, the padding strip 42, and the limiting strip 43 are an integrally formed structure or connected by welding. The clamping strip 41 and the limiting strip 43 are perpendicular to the padding strip 42. The clamping strip 41 is clamped in the clamping groove, and the padding 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 padding strip 42 using glass glue or structural glue. A pressure line 15 is set on the pressure seat 14 on the inner side of the second frame 2. The pressure line 15 is clamped with the pressure seat 14, and one side of the pressure line 15 is pressed tightly against the second glass 11 by a glue strip.

[0035] 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 by using glass glue or structural glue. Figure 3 As shown, the inner size of the middle sealing frame 7 is smaller than the inner size 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 of the sealed cavity and the integrity of the structure.

[0036] Of course, the middle sealing frame 7 may also be sealed and glued 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.

[0037] It should be noted that the first limiting frame 3 may also adopt the same structural form as the second limiting frame 4 , that is, be engaged with the first frame 1 .

[0038] Optionally, the second limiting frame 4 may adopt the same integral frame structure as the second frame 2, or may adopt multiple independent strip limiting structures, such as Figure 4 As shown, the second limiting frame 4 includes a plurality of independent second limiting units, and glass glue or structural glue is set between two 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 glue. There can be two, three, four or more second limiting units. Figure 4 The figure shows five second limiting units, that is, the top of the second limiting frame 4 is composed of five second limiting units, which can reduce the use of materials and reduce the weight and cost of doors and windows. In addition, the first limiting frame 3 can also adopt multiple independent strip limiting structures.

[0039] 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 42. A sink is opened on the pad 42, and a threaded hole is opened in the sink. The second frame 2 has a corresponding threaded hole. The pad 42 can be fixed to the second frame 2 by bolts.

[0040] The first limiting frame 3 and the second limiting frame 4 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). 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 can reduce the use of materials. The cross section of the middle sealing frame 7 can also be rectangular.

[0041] 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 hose. 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 arrangement of the air holes 18 of the casement window is shown in the figure. The same arrangement can be adopted for the sliding window. For the fixed window, the air nozzle 20 can be provided on the indoor side of the muntin or frame.

[0042] It is understandable that since a sealed cavity is formed between the middle sealing frame 7, the first glass 10, and the second glass 11, the sealed cavity can be evacuated and filled with functional gas through the gas nozzle 20. During the vacuuming process, the first glass 10 and the second glass 11 will be subjected to the force of atmospheric pressure. Since 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, thereby preventing the middle sealing frame 7 from being squeezed by the two glasses and ensuring the sealing of the sealed cavity. Among them, the equipment for vacuum replacement of the sealed cavity can adopt the single-mouth insulating glass offline filling and exhaust equipment disclosed in the Chinese utility model patent with authorization announcement number CN204387688U invented by the inventor.

[0043] At the same time, since the KTK vacuum replacement integrated gas doors and windows are vacuum replaced after all structures are installed, vacuum replacement can be carried out at any time. Users or manufacturers can repeatedly vacuum, inflate or replace the gas in the sealed cavity as needed throughout the life cycle of the doors and windows, which completely solves the problem of irreversible performance degradation of traditional inflatable doors and windows due to the attenuation of gas purity, ensuring that the thermal insulation and sound insulation performance are maintained in the best state 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 a low-pressure environment on the plateau, conventional insulating glass cannot adjust its internal air pressure and may bulge, while the gas pressure in the sealed cavity of the present invention can be adjusted during on-site installation, or vacuum replacement can be performed during on-site installation.

[0044] In addition, the present invention utilizes the inherent characteristics of the thermal break door frame to form a hollow belt (i.e., a sealed cavity) containing functional gas at the thermal break, and can further improve the heat insulation, thermal insulation, and noise reduction performance by setting multiple hollow belts.

[0045] The above is the basic structure of the KTK vacuum replacement integrated gas door and window. Other structures can be added on this basis, for example, Figure 10 As shown, conventional insulating glass can be directly bonded to the side of the first glass 10 or the second glass 11 away from the middle sealing frame 7 using glass glue, an insulation strip 23 is set between the second glass 11 and the insulating glass, and the insulating glass is pressed tightly using a pressure line 15, or more sealing cavities are set.

[0046] like Figure 5As shown, it illustrates the situation of adding an adjustment cavity 22 on the side close to the second glass 11. Three card slots are provided on the inner side of the second frame 2. The third limiting frame 5 is clamped in the second card slot, and the fourth limiting frame 6 is clamped in the third card slot. The third limiting frame 5 is fixedly connected to the second glass 11 and the second limiting frame 4 by glass glue or structural glue. 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 and glued to the third limiting frame 5, the fourth limiting frame 6, the second glass 11, and the third glass 12, so that a sealed adjustment cavity 22 is formed between the right sealing frame 9, the second glass 11, and the third glass 12. Similarly, an air hole 18 can be provided on the right sealing frame 9 and connected to the air pipe 19. The air pipe 19 on the right sealing frame 9 passes through the second frame 2 and is connected to the air nozzle 20 on the second frame 2.

[0047] like Figure 6 As shown, it shows the situation of adding adjustment cavity 22 on both sides. Figure 5 The adjustment cavity 22 has the same structure. The first frame 1 is provided with two card slots, and the fifth limit frame 16 and the sixth limit frame 17 are respectively clamped in the two card slots. The fifth limit frame 16 is fixedly connected to the first glass 10 by glass glue or structural glue. A left sealing frame 8 is arranged between the fifth limit frame 16 and the sixth limit frame 17. The fourth glass 13 is fixedly glued to the sixth limit frame 17. The left sealing frame 8 is sealed and glued to the fifth limit frame 16, the sixth limit frame 17, the first glass 10, and the fourth glass 13, so that a sealed adjustment cavity 22 is formed between the left sealing frame 8, the first glass 10, and the fourth glass 13. Similarly, an air hole 18 can be provided on the left sealing frame 8 and connected to the 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.

[0048] In order to adapt to the above situation of adding other insulating glass or adjusting the cavity 22, the position of the pressure seat 14 of the present invention is adjustable, such as Figure 9 As shown, taking the first frame 1 as an example, the first frame 1 has multiple mounting holes, and nuts corresponding to the mounting holes are welded to the inside 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 waist-shaped hole can be provided on the first frame 1, and multiple bolts are set in the waist-shaped hole. The bolts can slide along the length of the waist-shaped hole, and the pressure seat 14 can be fixed to the first frame 1 by the nuts. In addition, the position of the pressure seat 14 can also be fixed, and by replacing the pressure wire 15 of different sizes, it can also adapt to the situation of adding other insulating glass or adjusting the cavity 22.

[0049] Figures 2 to 10 The structural shape in the figure is only for reference. The specific structural style shall be designed according to the requirements. Figure 11A schematic diagram of a product manufactured by the applicant, indicating its specific dimensions but not the glass.

[0050] In the present invention, molecular sieves are arranged between two adjacent glasses.

[0051] The manufacturing method of the KTK vacuum replacement integrated gas door and window includes: S1, sealingly gluing the first glass 10 to the first frame 1 and the first limiting frame 3; Step S1 specifically includes: After the frame (the frame includes the first frame 1, the second frame 2 and the broken bridge between the two), the glass and the second limit frame 4 are made, glass glue is applied on the inside of the first frame 1 and one side of the first limit frame 3, and the first glass 10 is fixed from the first frame 1 to the second frame 3. Figure 2 The left side of the frame is mounted on the first limiting frame 3 so that the first glass 10 is fixed on the first frame 1 and the first limiting frame 3 by glass glue.

[0052] S2. Place the middle sealing frame 7 between the first frame 1 and the second frame 2, and seal the middle sealing frame 7 with the first glass 10 and the first limiting frame 3; Step S2 specifically includes: Apply glass glue on the first limiting frame 3 and the first glass 10, place the middle sealing frame 7 in the second frame 2, and push the middle sealing frame 7 toward 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 through the glass glue.

[0053] It should be noted that the first limiting frame 3 of the present invention can be staggered with the side of the first frame 1 close to the second frame 2, that is, the first limiting frame 3 is staggered toward 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.

[0054] S3, clamping the second limiting frame 4 to the second frame 2, and sealing the second limiting frame 4 to the middle sealing frame 7; Step S3 specifically includes: Apply glass glue on 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 the glass glue.

[0055] S4, installing the second glass 11 on the second limiting frame 4, and sealing the second glass 11 with the second limiting frame 4 and the middle sealing frame 7; Step S4 specifically includes: Apply glass glue on the side of the middle sealing frame 7 away from the first glass 10 and on the gasket strip 42 and the limiting strip 43 of the second limiting frame 4. If the second limiting frame 4 includes multiple independent second limiting units, it is also necessary to apply glass glue between two adjacent second limiting units, and install the second glass 11 on the second limiting frame 4 so that the second glass 11 is sealed with the second limiting frame 4 and the middle sealing frame 7.

[0056] S5. If an adjustment cavity 22 is required, the limiting frame and glass corresponding to the adjustment cavity 22 are installed according to the steps of S3 and S4.

[0057] S6. Perform vacuum replacement on the sealed cavity.

[0058] Step S5 specifically includes: The gas in the sealed cavity is extracted using the gas nozzle 20, and a functional gas (such as helium) is injected into the sealed cavity; The above operation can be performed once or multiple times; when the above operation is performed 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 20 can be closed; when the above operation is performed multiple times, the sealed cavity can be evacuated to a value less than the standard value, and then the functional gas can be filled into the sealed cavity, and then the sealed cavity can be evacuated again to a value less than the standard value, and then the functional gas can be filled into the sealed cavity again. After several cycles, the concentration requirement of the functional gas in the sealed cavity can be met.

[0059] If an adjustment cavity 22 is provided, the same method can be used to perform vacuum replacement on the adjustment cavity 22 .

[0060] The KTK vacuum replacement integrated gas doors and windows can also be used in the thermal insulation system of the building's exterior envelope, such as sun roofs and glass curtain walls.
