Description

Technical Field

[0001] This invention relates to the field of glass curtain wall technology, specifically to an insulated glass curtain wall that can prevent condensation on the inner side and in the interlayer. Background Technology

[0002] The invention patent with publication number CN113027016A discloses a passive anti-condensation heating and temperature-controlled glass curtain wall for houses. It states that: the dew point temperature is obtained by consulting a commonly used temperature and humidity chart, and then the lowest temperature at the temperature control switch is set as the dew point temperature. When the temperature is lower than the dew point temperature, the temperature control switch will automatically turn on and power on for heating.

[0003] The above solution overlooks a crucial factor: both indoor temperature and relative humidity are in a state of flux, meaning that dew point temperature and humidity are changing. For example, after mopping the floor, relative humidity increases significantly.

[0004] Meanwhile, if a temperature-controlled air conditioning device, such as an air conditioner, is turned on indoors, and the air conditioner blows towards the curtain wall, it will also cause a mismatch between the dew point temperature and the indoor temperature and relative humidity. Therefore, the above solution cannot completely eliminate the condensation phenomenon inside the glass curtain wall.

[0005] Insulating glass consists of two panes of glass, one inner and one outer, with a sandwich layer between them. This sandwich layer can be made of air or an inert gas. The sandwich layer and the glass are sealed together by a sealing strip. Due to factors such as sunlight exposure, the sealing strip may age and shrink, causing the seal between the glass sandwich layer to weaken. Once the seal weakens, moisture may enter and remain, easily leading to condensation in the sandwich layer. When condensation occurs in the sandwich layer, it is difficult to drain and restore the sandwich layer.

[0006] Therefore, a double-glazed curtain wall that can prevent condensation on the inner side and in the interlayer is proposed to address the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide an insulated glass curtain wall that can prevent condensation on the inner side and in the interlayer, so as to solve the problem mentioned in the background art of "how to heat the glass before the dew point temperature is reached when the temperature is changing".

[0008] To achieve the above objectives, the present invention provides the following technical solution: a double-glazed curtain wall capable of preventing condensation on the inner side and in the interlayer, comprising a frame, an inner glass facing the interior and an outer glass facing the exterior, an interlayer between the inner and outer glass, a sealing ring provided on the outer edge of the interlayer, the sealing ring being fixedly connected to the frame, a circular through hole communicating with the inner side of the sealing ring, a heat-conducting column fixedly connected to the inner side of the sealing ring, an elastic metal plate fixedly connected to the side of the heat-conducting column facing the interlayer, the elastic metal plate being in contact with the inner side of the sealing ring, and by blowing hot air into the circular through hole, heat will be transferred to the interlayer through the heat-conducting column and the elastic metal plate, thereby heating the interlayer;

[0009] A temperature-sensing metal plate is fixedly connected to the bottom of the frame facing the outside. A heat pipe is fixedly connected to the inner side of the bottom of the frame. The temperature-sensing metal plate is connected to the heat pipe. An inner inclined groove is opened on the bottom of the frame facing the inside. A cooling plate is fixedly connected to the inner side of the bottom of the inner inclined groove. When the temperature drops, because the cooling plate is connected to the temperature-sensing metal plate outside through the heat pipe, the temperature of the cooling plate will be lower than that of the rest of the inner glass. However, since they are all in the same indoor environment, condensation will occur on the cooling plate first. After the condensation is detected, the inner side of the interlayer is heated to prevent condensation on the inner glass.

[0010] Since condensation mainly occurs in winter, when indoor temperatures are high and outdoor temperatures are low, when indoor temperatures are high and relative humidity is high, condensation will occur on the inner glass of the curtain wall due to the low temperature, thus affecting the view and aesthetics. Compared with the existing technology, the present invention can more accurately judge the timing of condensation, thereby effectively reducing the working time required for heating devices to prevent condensation on the curtain wall, and playing a role in reducing building energy consumption.

[0011] As a preferred embodiment of the insulated glass curtain wall of the present invention capable of preventing condensation on the inner side and in the interlayer, a hot air duct is fixedly connected to one side of the bottom end of the frame. The two ends of the hot air duct are an exhaust pipe and an exhaust pipe, respectively. A fan and an electric heating grid are fixedly connected to the inner side of the hot air duct. The bottom end of the circular through hole is separated by a partition, and an exhaust port and an exhaust port are respectively provided on both sides of the partition. The exhaust pipe passes through the bottom end of the frame and connects to the exhaust port, and the exhaust pipe passes through the bottom end of the frame and connects to the exhaust port.

[0012] Under the above settings, when the fan and electric heating network are working, hot air will enter the inner side of the circular through hole through the air outlet pipe and air outlet. The present invention achieves heating of the circular through hole through an external hot air tube. The function of the isolation is to achieve a large circulation, so that the hot air is heated again by the hot air tube after circulating around the circular through hole once.

[0013] As a preferred embodiment of the insulated glass curtain wall of the present invention capable of preventing condensation on the inner side and interlayer, a gauze is fixedly connected to the upper side of the cooling plate, the gauze is wrapped with soluble conductive particles, the top of the cooling plate is provided with an arc-shaped part, and the gauze is placed in the arc-shaped part. When condensation occurs on the cooling plate, the dew on its surface will concentrate towards the arc-shaped part and be absorbed by the capillary effect of the gauze. The soluble conductive particles in the gauze dissolve, making the gauze conductive.

[0014] As a preferred embodiment of the insulated glass curtain wall of the present invention capable of preventing condensation on the inner side and in the interlayer, a power supply and an inductor controller are fixedly connected to the lower side of the inner inclined groove of the frame. Two contacts are fixed at the center of the cooling plate. The two contacts are covered with gauze. After the gauze conducts electricity, a closed-loop circuit is formed between the power supply, the inductor controller, the contacts, and the gauze. The inductor controller controls the operation of the fan and the electric heating network to circulate hot air into the circular through hole. The power supply, the inductor controller, the contacts, and the gauze are connected by wires. The inductor controller is existing technology and will not be elaborated on here. It achieves detection by detecting the current in the closed-loop circuit, thereby acting as a start switch.

[0015] As the curtain wall is heated, the gauze becomes conductive after being slightly soaked. The liquid inside the gauze is small and not fluid. After the moisture evaporates, the salt remains inside the gauze for the next use.

[0016] Because the cooling plate is connected to the outdoor temperature-sensitive metal plate via heat pipes, the cooling plate shares the same indoor humidity and relative humidity as the inner glass, but has a lower temperature. This controls condensation within the inner inclined groove. When condensation occurs in the inner inclined groove, the dew on the cooling plate's surface merges and concentrates towards the arc-shaped part, where it is absorbed by the capillary action of the gauze. The soluble conductive particles in the gauze dissolve, and after the gauze becomes wet, these particles dissolve and become conductive. These soluble conductive particles can be salts, etc. Once the gauze becomes conductive, a closed-loop circuit is formed between the power supply, the inductor controller, the contacts, and the gauze. The inductor controller controls the fan and the heating grid to circulate hot air into the circular through-hole. The heat is transferred to the inner side of the interlayer through the heat-conducting column and the elastic metal plate, heating the interlayer and raising the glass temperature, thus preventing condensation.

[0017] As a preferred embodiment of the present invention for an insulated glass curtain wall that can prevent condensation on the inner side and in the interlayer, the heat pipes and the temperature-sensitive metal plate can be set at multiple points in other locations. The heat pipes set at multiple points in other locations do not need to reach the inner glass, but only need to reach the sealing ring. The sealing ring is selected as thermally conductive silicone. The bottom end of the sealing ring contacts the heat pipe, so that the temperature of the elastic metal plate on the inner edge of the sealing ring remains at a low level in the interlayer, so that condensation occurs at the elastic metal plate. The space and water vapor in the interlayer are extremely limited, thereby preventing excessive condensation from accumulating on the glass.

[0018] Under the above configuration, the present invention can also prevent fogging in the interlayer. As the curtain wall is used, the sealing performance may decrease, which may cause water vapor to enter the inner side of the interlayer. In the present invention, since low temperature points are also set around the interlayer, and the space and water vapor in the interlayer are extremely limited, the air in the interlayer will preferentially condense on the elastic metal plate, thereby preventing excessive condensation from accumulating on the glass.

[0019] As a preferred embodiment of the insulated glass curtain wall of the present invention, which can prevent condensation on the inner side and interlayer, an air nozzle is fixedly connected to the hot air duct, and the air nozzle can realize the inflation and deflation of the circular through hole.

[0020] As a preferred embodiment of the present invention, an insulated glass curtain wall capable of preventing condensation on the inner side and interlayer, has gaps at both the bottom and top of the inner glass.

[0021] In this invention, compared to the fixed sealing strip in the prior art, the sealing strip in this invention has a pressure relief space, which is a circular through hole. The pressure relief space can repair the sealing performance by expanding, and can connect the interlayer with the outside by contracting, so as to remove air, thereby increasing the service life of the curtain wall's sealing performance. The moisture-absorbing component is changed from being placed directly inside the interlayer to being placed on the outside of the frame, so that the moisture-absorbing component can be replaced and the dryness of the interlayer can be guaranteed.

[0022] As a preferred embodiment of the insulated glass curtain wall of the present invention capable of preventing condensation on the inner side and in the interlayer, the frame is provided with vents on the upper and lower sides facing the interior for the discharge of water vapor inside the interlayer, and a moisture-absorbing element is attached to the lower side of the frame facing the interior for removing water vapor from the air entering the interlayer.

[0023] When the curtain wall is heated and the circular through-holes shrink, the upper part of the interlayer is provided with gaps and air vents as outlets for water vapor. The lower part of the interlayer is sucked in to replenish the air. The gas will enter the interior of the interlayer through the moisture-absorbing component, achieving unlimited drying of the air inside the interlayer.

[0024] As a preferred embodiment of the insulated glass curtain wall of the present invention capable of preventing condensation on the inner side and in the interlayer, the overall cross-section of the sealing ring is approximately trapezoidal, with the top of the sealing ring being a downward arched portion. The elastic metal plate bends downward, and when air is injected into the inner side of the circular through-hole, the circular through-hole radiates outward in a circular manner, causing the deformation in the middle of the elastic metal plate to be greater than that at both ends of the elastic metal plate. The middle of the elastic metal plate moves towards the interlayer, causing the two ends of the elastic metal plate to press against the glass on both sides and form pressing portions on both sides of the sealing ring. Thus, after the sealing ring is injected with air through the circular through-hole, it has a strong sealing performance against the glass on both sides.

[0025] Compared with the prior art, the sealing ring in this invention, after being inflated through the circular through hole, cooperates with the elastic metal plate to press the glass and form a pressing part, which greatly increases the sealing performance. It does not require high installation accuracy, nor does it require complete pressing during the installation process, thus reducing the installation difficulty.

[0026] The flexible metal plate is also used for heat conduction and as a surface for condensation formation, preventing condensation from appearing on the glass.

[0027] As a preferred embodiment of the insulated glass curtain wall of the present invention capable of preventing condensation on the inner side and in the interlayer, the waist of the sealing ring is a hollow part. As the pressure inside the circular through hole increases, the hollow part gradually comes closer to the glass, thereby further increasing the sealing effect.

[0028] When the humidity inside the interlayer is too high, air is released through the air nozzle. As the pressure inside the circular through hole decreases, the elastic metal plate bends towards the frame. The deformation in the middle of the elastic metal plate is still greater than that at both ends, causing the ends of the elastic metal plate to move away from the glass on both sides, allowing the void to gradually separate from the glass. This creates a gap between the sealing ring and the glass. Even after the gap is created, hot air can still be injected into the circular through hole, thereby heating the interlayer and expelling the moisture.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. This is a type of insulated glass curtain wall that can prevent condensation on the inner side and in the interlayer. Condensation mainly occurs in winter when the indoor temperature is high and the outdoor temperature is low. When the indoor temperature is high and the relative humidity is high, condensation will occur on the inner side of the curtain wall due to the low temperature, which will affect the view and aesthetics. Compared with the prior art, the present invention can more accurately judge the timing of condensation, thereby effectively reducing the working time required for heating devices to prevent condensation on the curtain wall and playing a role in reducing building energy consumption.

[0031] 2. This type of insulated glass curtain wall can prevent condensation on the inner side and interlayer. When the fan and electric heating network are working, hot air will enter the inner side of the circular through hole through the air outlet and air outlet. This invention achieves heating of the circular through hole through an external hot air tube. The function of the partition is to achieve a large circulation, so that the hot air is heated again by the hot air tube after circulating around the circular through hole.

[0032] 3. This type of insulated glass curtain wall, capable of preventing condensation on the inner side and in the interlayer, becomes conductive after the gauze is slightly soaked when the curtain wall is heated. The liquid inside the gauze is minimal and non-flowing. After the water evaporates from the gauze, the salt remains inside for future use. Because the cooling plate is connected to the outdoor temperature-sensitive metal plate via heat pipes, the cooling plate shares the same indoor humidity and relative humidity as the inner glass, but has a lower temperature. This systematically controls condensation within the inner inclined groove. When condensation occurs within the inner inclined groove, the cooling plate... The dew on its surface will merge and concentrate towards the arc-shaped part and be absorbed by the capillary effect of the gauze. The soluble conductive particles in the gauze dissolve. After the gauze is wet, the soluble conductive particles dissolve and open up, making the gauze conductive. The soluble conductive particles can be salts, etc. After the gauze becomes conductive, a closed-loop circuit is formed between the power supply, the inductor controller, the contacts, and the gauze. The inductor controller controls the fan and the electric heating grid to work, circulating hot air into the circular through hole. The heat is transferred to the inside of the interlayer through the heat-conducting column and the elastic metal plate, realizing the heating of the interlayer. The glass temperature is increased by heating, thereby avoiding condensation.

[0033] 4. This invention provides a type of insulated glass curtain wall that can prevent condensation on the inner side and in the interlayer. It can also prevent fogging in the interlayer because the sealing performance may decrease with the use of the curtain wall, which can cause water vapor to enter the inner side of the interlayer. In this invention, low temperature points are also set around the interlayer, and the space and water vapor in the interlayer are extremely limited. The air in the interlayer preferentially condenses on the elastic metal plate, thereby preventing excessive condensation from accumulating on the glass.

[0034] 5. This type of insulated glass curtain wall, which can prevent condensation on the inner side and in the interlayer, has a pressure relief space in the sealing strip of the present invention, compared with the fixed sealing strip in the prior art. The pressure relief space is a circular through hole. The pressure relief space can restore the sealing performance by expanding and can connect the interlayer with the outside by contracting to remove air, thereby increasing the service life of the curtain wall's sealing performance. The moisture-absorbing component is changed from being placed directly inside the interlayer to being placed on the outside of the frame, so that the moisture-absorbing component can be replaced and the dryness of the interlayer can be guaranteed.

[0035] 6. This type of insulated glass curtain wall can prevent condensation on the inner side and in the interlayer. When the curtain wall is heated and the circular through-hole shrinks, the upper part of the interlayer is provided with gaps and air vents as water vapor outlets. The lower part of the interlayer is sucked in to replenish the air. The gas will enter the interior of the interlayer through the moisture-absorbing component, so as to achieve unlimited drying of the air inside the interlayer.

[0036] 7. This type of insulated glass curtain wall can prevent condensation on the inner side and in the interlayer. After the sealing ring in the circular through hole is filled with air, it cooperates with the elastic metal plate to press the glass and form a pressing part, which greatly increases the sealing performance. It does not require high installation accuracy and does not need to ensure full pressing during the installation process, thus reducing the installation difficulty. Attached Figure Description

[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below 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.

[0054] Example 1, please refer to Figures 1-6 , Figure 8 and Figure 9 The present invention provides a technical solution:

[0055] A double-glazed curtain wall capable of preventing condensation on the inner side and in the interlayer includes a frame 1, an inner glass 7 facing the interior and an outer glass 6 facing the exterior. An interlayer is formed between the inner glass 7 and the outer glass 6. A sealing ring 2 is provided on the outer edge of the interlayer. The sealing ring 2 is fixedly connected to the frame 1. A circular through hole 21 is connected to the inner side of the sealing ring 2. A heat-conducting column 25 is fixedly connected to the inner side of the sealing ring 2. An elastic metal plate 24 is fixedly connected to the side of the heat-conducting column 25 facing the interlayer. The elastic metal plate 24 is in contact with the inner side of the sealing ring 2. By blowing hot air into the circular through hole 21, heat is transferred to the interlayer through the heat-conducting column 25 and the elastic metal plate 24, thereby heating the interlayer.

[0056] A temperature-sensing metal plate 8 is fixedly connected to the bottom of the frame 1 facing the outside. A heat pipe 85 is fixedly connected to the inner side of the bottom of the frame 1. The temperature-sensing metal plate 8 is connected to the heat pipe 85. An inner inclined groove 9 is opened on the bottom of the frame 1 facing the inside. A cooling plate 81 is fixedly connected to the inner side of the bottom of the inner inclined groove 9. When the temperature drops, because the cooling plate 81 is connected to the temperature-sensing metal plate 8 outside through the heat pipe 85, the temperature of the cooling plate 81 will be lower than that of the rest of the inner glass 7. However, they are all in the same indoor environment. Condensation will occur on the cooling plate 81 first. After the condensation is detected, the inner side of the interlayer is heated to prevent condensation on the inner glass 7.

[0057] Since condensation mainly occurs in winter, when indoor temperatures are high and outdoor temperatures are low, when indoor temperatures are high and relative humidity is high, condensation will occur on the inner glass of the curtain wall due to the low temperature, thus affecting the view and aesthetics. Compared with the existing technology, the present invention can more accurately judge the timing of condensation, thereby effectively reducing the working time required for heating devices to prevent condensation on the curtain wall, and playing a role in reducing building energy consumption.

[0058] As a preferred embodiment of the insulated glass curtain wall of the present invention capable of preventing condensation on the inner side and in the interlayer, a hot air duct 5 is fixedly connected to one side of the bottom end of the frame 1. The two ends of the hot air duct 5 are an exhaust pipe 51 and an exhaust pipe 52, respectively. A fan 53 and an electric heating grid 55 are fixedly connected to the inner side of the hot air duct 5. The bottom end of the circular through hole 21 is separated by a partition 211. An exhaust port 511 and an exhaust port 521 are respectively provided on both sides of the partition 211. The exhaust pipe 51 passes through the bottom end of the frame 1 and connects to the exhaust port 511. The exhaust pipe 52 passes through the bottom end of the frame 1 and connects to the exhaust port 521.

[0059] Under the above settings, when the fan 53 and the electric heating network 55 are working, hot air will enter the inner side of the circular through hole 21 through the air outlet 52 and the air outlet 521. The present invention heats the circular through hole 21 by means of an external hot air tube 5. The function of the partition 211 is to realize a large circulation, so that the hot air is heated again by the hot air tube 5 after circulating around the circular through hole 21.

[0060] As a preferred embodiment of the insulated glass curtain wall of the present invention capable of preventing condensation on the inner side and in the interlayer, a gauze 84 is fixedly connected to the upper side of the cooling plate 81. The gauze 84 is filled with soluble conductive particles. An arc-shaped part 812 is provided at the top of the cooling plate 81, and the gauze 84 is disposed in the arc-shaped part 812. When condensation occurs on the cooling plate 81, the dew droplets on its surface will concentrate towards the arc-shaped part 812 and be absorbed by the capillary effect of the gauze 84. The soluble conductive particles in the gauze 84 dissolve, making the gauze 84 conductive.

[0061] As a preferred embodiment of the hollow glass curtain wall of the present invention capable of preventing condensation on the inner side and in the interlayer, the frame 1 is fixedly connected to a power supply 82 and an inductor controller 83 on the lower side of the inner inclined groove 9. Two contacts 811 are fixed at the center of the cooling plate 81. The two contacts 811 are covered by gauze 84. After the gauze 84 conducts electricity, a closed-loop circuit is formed between the power supply 82, the inductor controller 83, the contacts 811 and the gauze 84. The inductor controller 83 controls the operation of the fan 53 and the electric heating grid 55 to circulate hot air into the circular through hole 21. The power supply 82, the inductor controller 83, the contacts 811 and the gauze 84 are connected by wires. The inductor controller 83 is prior art and will not be described in detail here. It detects the current in the closed-loop circuit and thus acts as a start switch.

[0062] As the curtain wall is heated, the gauze becomes conductive after being slightly soaked in gauze 84. The liquid inside the gauze 84 is small and not fluid. After the water in the gauze 84 evaporates, the salt remains inside the gauze 84 for the next use.

[0063] Because the cooling plate 81 is connected to the outdoor temperature-sensing metal plate 8 via the heat pipe 85, the cooling plate 81 shares the same indoor humidity and relative humidity as the inner glass, but has a lower temperature than the indoor environment. This allows condensation to be controlled systematically within the inner inclined groove 9. When condensation occurs within the inner inclined groove 9, the dewdrops on the surface of the cooling plate 81 will merge and concentrate towards the arc-shaped portion 812 and be absorbed by the capillary action of the gauze 84. The soluble conductive particles in the gauze 84 dissolve, and the gauze 84 becomes wet. Soluble conductive particles dissolve and become conductive, making the gauze 84 conductive. These soluble conductive particles can be salts, etc. After the gauze 84 becomes conductive, a closed-loop circuit is formed between the power supply 82, the inductor controller 83, the contact 811, and the gauze 84. The inductor controller 83 controls the fan 53 and the heating grid 55 to work, circulating hot air into the circular through hole 21. The heat is transferred to the inner side of the interlayer through the heat-conducting column 25 and the elastic metal plate 24, thereby heating the interlayer and increasing the glass temperature to avoid condensation.

[0064] As a preferred embodiment of the insulated glass curtain wall of the present invention capable of preventing condensation on the inner side and in the interlayer, the heat pipe 85 and the temperature-sensing metal plate 8 can be set at multiple points in other locations. The heat pipe 85 set at multiple points in other locations does not need to reach the inner glass 7, but only needs to reach the sealing ring 2. The sealing ring 2 is selected as thermally conductive silicone. The bottom end of the sealing ring 2 contacts the heat pipe 85, so that the temperature of the elastic metal plate 24 on the inner edge of the sealing ring 2 remains at a low level in the interlayer, so that condensation occurs at the elastic metal plate 24. The space and water vapor in the interlayer are extremely limited, thereby preventing excessive condensation from accumulating on the glass.

[0065] Under the above configuration, the present invention can also prevent fogging in the interlayer. As the curtain wall is used, the sealing performance may decrease, which may cause water vapor to enter the inner side of the interlayer. In the present invention, since low temperature points are also set around the interlayer, and the space and water vapor in the interlayer are extremely limited, the air in the interlayer preferentially condenses on the elastic metal plate 24, thereby preventing excessive condensation from accumulating on the glass.

[0066] A water-sensitive color-changing coating can be applied to the flexible metal plate 24, allowing indoor personnel to observe the moisture level and manually turn on the heater and remove moisture in a timely manner.

[0067] Example 2 is a further improvement upon Example 1. Please refer to Example 1. Figures 1-11 An air nozzle 54 is fixedly connected to the hot air duct 5, which allows for the inflation and deflation of the circular through hole 21.

[0068] As a preferred embodiment of the present invention, which can prevent condensation on the inner side and in the interlayer, gaps 71 are provided at both the bottom and top of the inner glass 7.

[0069] In this invention, compared to the fixed sealing strip in the prior art, the sealing strip in this invention has a pressure relief space, which is a circular through hole 21. The pressure relief space can repair the sealing performance by expanding, and can connect the interlayer with the outside by contracting, so as to remove air, thereby increasing the service life of the curtain wall's sealing performance. The moisture-absorbing component is changed from being directly placed inside the interlayer to being placed on the outside of the frame, so that the moisture-absorbing component can be replaced and the dryness of the interlayer can be guaranteed.

[0070] As a preferred embodiment of the insulated glass curtain wall of the present invention capable of preventing condensation on the inner side and in the interlayer, the frame 1 is provided with air vents 4 on the upper and lower sides facing the interior for the discharge of water vapor inside the interlayer, and a moisture-absorbing element 3 is attached to the lower side facing the interior of the frame 1 for removing water vapor from the air entering the interlayer.

[0071] When the curtain wall is heated and the circular through hole 21 contracts, the upper part of the interlayer is provided with a gap 71 and an air outlet 4 as a water vapor outlet, and the lower part of the interlayer is sucked in to replenish it. The gas will enter the interior of the interlayer through the moisture absorber 3, so as to achieve unlimited drying of the air inside the interlayer.

[0072] Example 3 is a further improvement upon Example 1. Please refer to Example 1 for details. Figures 1-11 The overall cross-section of the sealing ring 2 is approximately trapezoidal, with the top of the sealing ring 2 being a lower arch 26. The elastic metal plate 24 bends downward and is inflated into the inner side of the circular through hole 21. The circular through hole 21 expands outward in a circular manner, causing the deformation in the middle of the elastic metal plate 24 to be greater than that at both ends. The middle of the elastic metal plate 24 moves towards the interlayer, causing the two ends of the elastic metal plate 24 to press against the glass on both sides and form pressing parts 23 on both sides of the sealing ring 2. Thus, after the sealing ring 2 is inflated through the circular through hole 21, it has a strong sealing performance against the glass on both sides.

[0073] Compared with the prior art, the sealing ring 2 in this invention, after being inflated in the circular through hole 21, cooperates with the elastic metal plate 24 to press the glass and form a pressing part 23, which greatly increases the sealing performance. It does not require high installation accuracy, nor does it require complete pressing during the installation process, thus reducing the installation difficulty.

[0074] The flexible metal plate 24 is also used for heat conduction and as a condensation-forming surface to prevent condensation from appearing on the glass.

[0075] As a preferred embodiment of the insulated glass curtain wall of the present invention that can prevent condensation on the inner side and in the interlayer, the waist of the sealing ring 2 is a hollow part 22. As the pressure inside the circular through hole 21 increases, the hollow part 22 gradually comes closer to the glass, thereby further increasing the sealing effect.

[0076] When the humidity inside the interlayer is too high, air is released through the air nozzle 54. As the pressure inside the circular through hole 21 decreases, the elastic metal plate 24 bends towards the frame 1. The deformation in the middle of the elastic metal plate 24 is still greater than that at both ends, causing the ends of the elastic metal plate 24 to move away from the glass on both sides, allowing the empty part 22 to gradually separate from the glass, thereby creating a gap between the sealing ring 2 and the glass. Even after the gap is created, hot air can still be injected into the circular through hole 21, thereby heating the interlayer and expelling the moisture.

[0077] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

Claims

1. A double-glazed curtain wall capable of preventing condensation on the inner side and in the interlayer, comprising a frame (1), an inner glass (7) facing the interior and an outer glass (6) facing the exterior, wherein the inner glass (7) and the outer glass (6) are interlayered, characterized in that: A sealing ring (2) is provided on the outer edge of the interlayer.

A heat-conducting column (25) is fixedly connected to the inner side of the sealing ring (2). An elastic metal plate (24) is fixedly connected to the side of the heat-conducting column (25) facing the interlayer. The elastic metal plate (24) is in contact with the inner side of the sealing ring (2). By blowing hot air into the circular through hole (21), the heat will be transferred to the interlayer through the heat-conducting column (25) and the elastic metal plate (24), thereby heating the interlayer. A temperature-sensitive metal plate (8) is fixedly connected to the bottom of the frame (1) facing the outside. A heat pipe (85) is fixedly connected to the inner side of the bottom of the frame (1). The temperature-sensitive metal plate (8) is connected to the heat pipe (85). An inner inclined groove (9) is opened on the bottom of the frame (1) facing the inside. A cooling plate (81) is fixedly connected to the inner side of the bottom of the inner inclined groove (9). When the temperature drops, because the cooling plate (81) is connected to the temperature-sensitive metal plate (8) outside through the heat pipe (85), the temperature of the cooling plate (81) will be lower than that of the rest of the inner glass (7). However, they are in the same indoor environment. The cooling plate (81) will condense first. After the condensation is detected, the inner side of the interlayer is heated to prevent the condensation of the inner glass (7). A hot air duct (5) is fixedly connected to one side of the bottom of the frame (1). The two ends of the hot air duct (5) are an exhaust pipe (51) and an exhaust pipe (52). A fan (53) and an electric heating grid (55) are fixedly connected to the inside of the hot air duct (5). The bottom of the circular through hole (21) is separated by a partition (211). An exhaust port (511) and an exhaust port (521) are respectively provided on both sides of the partition (211). The exhaust pipe (51) is connected to the exhaust port (511) through the bottom of the frame (1), and the exhaust pipe (52) is connected to the exhaust port (521) through the bottom of the frame (1). A gauze (84) is fixedly connected to the upper side of the cooling plate (81). Soluble conductive particles are wrapped inside the gauze (84). An arc-shaped part (812) is provided at the top of the cooling plate (81). The gauze (84) is placed inside the arc-shaped part (812). When condensation forms on the cooling plate (81), the dew on its surface will concentrate towards the arc-shaped part (812) and be absorbed by the capillary effect of the gauze (84). The soluble conductive particles inside the gauze (84) dissolve, making the gauze (84) conductive.

2. The insulated glass curtain wall according to claim 1, characterized in that: The frame (1) has a power supply (82) and an inductor controller (83) fixedly connected to the lower side of the inner inclined groove (9). Two contacts (811) are fixed at the center of the cooling plate (81). The two contacts (811) are covered by gauze (84). After the gauze (84) becomes conductive, a closed-loop circuit is formed between the power supply (82), the inductor controller (83), the contacts (811) and the gauze (84). The inductor controller (83) controls the fan (53) and the electric heating grid (55) to work, circulating hot air into the circular through hole (21).

3. A double-glazed curtain wall capable of preventing condensation on the inner side and in the interlayer, as described in claim 1 or 2, characterized in that: The heat pipe (85) and the temperature-sensing metal plate (8) can be set at multiple locations in other places. The heat pipe (85) set at multiple locations in other places does not need to reach the inner glass (7), but only needs to reach the sealing ring (2). The sealing ring (2) is selected as thermally conductive silicone. The bottom end of the sealing ring (2) contacts the heat pipe (85), so that the temperature of the elastic metal plate (24) on the inner edge of the sealing ring (2) remains low in the interlayer, so that condensation occurs at the elastic metal plate (24). The space and water vapor in the interlayer are extremely limited, thus preventing excessive condensation from accumulating on the glass. The surface of the elastic metal plate (24) can be provided with a coating or cloth that changes color when exposed to water.

4. A double-glazed curtain wall capable of preventing condensation on the inner side and in the interlayer as described in claim 1 or 2, characterized in that: A nozzle (54) is fixedly connected to the hot air duct (5), and the air can be filled and released through the circular through hole (21) through the nozzle (54).

5. A double-glazed curtain wall according to claim 4 that can prevent condensation on the inner side and in the interlayer, characterized in that: The bottom and top of the inner glass (7) are both provided with gaps (71).

6. A double-glazed curtain wall according to claim 5, characterized in that: The frame (1) has air vents (4) on the upper and lower sides facing the room for the discharge of water vapor inside the interlayer. The frame (1) has a moisture absorbent (3) attached to the lower side facing the room for the removal of water vapor from the air entering the interlayer.

7. A double-glazed curtain wall capable of preventing condensation on the inner side and in the interlayer as described in claim 1 or 2, characterized in that: The overall cross-section of the sealing ring (2) is approximately trapezoidal. The top of the sealing ring (2) is a lower arch (26). The elastic metal plate (24) bends downward and is filled with air into the inner side of the circular through hole (21). The circular through hole (21) radiates outward in a circular manner, causing the deformation in the middle of the elastic metal plate (24) to be greater than that at both ends of the elastic metal plate (24). The middle of the elastic metal plate (24) moves towards the interlayer, causing the two ends of the elastic metal plate (24) to press against the glass on both sides and form pressing parts (23) on both sides of the sealing ring (2). Thus, after the sealing ring (2) is filled with air through the circular through hole (21), it has a strong sealing performance against the glass on both sides.

8. A double-glazed curtain wall according to claim 7, characterized in that: The waist of the sealing ring (2) is a hollow part (22). As the pressure inside the circular through hole (21) increases, the hollow part (22) gradually gets closer to the glass, thereby further increasing the sealing effect. When the humidity inside the interlayer is too high, air is drawn out through the air nozzle (54). As the pressure inside the circular through hole (21) decreases, the empty part (22) gradually separates from the glass, thereby creating a gap between the sealing ring (2) and the glass. Even after the gap is created, hot air can still be injected into the circular through hole (21), thereby heating the interlayer and expelling the moisture.
