Description

Technical Field

[0001] This utility model relates to the field of insulated glass technology, and more specifically, to an insulated glass. Background Technology

[0002] Insulating glass, widely used in construction and transportation, is favored by the market for its excellent heat and sound insulation properties. This material not only effectively reduces heat exchange between indoors and outdoors, lowering energy consumption for air conditioning and heating, but also significantly reduces noise, improving the comfort of living and working environments. Traditional insulating glass typically consists of two or more panes of glass separated by spacers to form one or more closed cavities, sealed at the edges with high-performance sealant to ensure a dry internal environment, thus preventing condensation and fogging on the inner surface of the glass due to moisture ingress.

[0003] However, in practical use, insulated glass faces a common challenge: the "breathing effect." This phenomenon is mainly caused by fluctuations in the pressure difference between the inside and outside due to temperature changes. When the outside temperature rises, the air inside the cavity expands due to heat, increasing pressure, and may seep out through tiny gaps in the sealing layer. Conversely, when the outside temperature drops, the air inside the cavity cools and contracts, decreasing pressure, allowing outside air to seep in through these gaps. This repeated gas exchange process leads to a gradual increase in humidity inside the cavity, affecting the glass's light transmittance and lifespan. When the humidity inside the cavity increases, condensation easily forms on the inner surface of the glass, creating water vapor. This not only reduces the glass's light transmittance and affects visibility but also accelerates the aging of the sealant, further reducing the sealing performance of the insulated glass. Furthermore, prolonged exposure to high humidity can cause mold and corrosion on the glass surface, severely impacting its appearance and lifespan. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes an insulated glass to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A type of insulated glass includes a frame, a first glass plate connected inside the frame, a second glass plate on one side of the first glass plate, the second glass plate being connected to the frame, a cavity between the first and second glass plates, a dehumidification mechanism inside the frame, the dehumidification mechanism including a groove inside the frame, a placement box slidably connected inside the groove, a through hole on one side of the placement box, a vent hole on the other side, a vent sheet connected inside the vent hole, and a desiccant inside the placement box.

[0007] Furthermore, in order to ensure the breathability of the breathable sheet and prevent dust from clogging the micropores, the breathable sheet is a porous ceramic breathable sheet, and the outer surface of the breathable sheet is covered with a microporous PE film.

[0008] Furthermore, to prevent gas from entering the cavity from the outside of the placement box, a baffle is fixedly connected inside the groove, and a sealing gasket is fixedly connected to one side of the baffle.

[0009] Furthermore, mounting plates are fixedly connected to both sides of the box. The mounting plates are connected to the frame by bolts. The mounting plates are provided with mounting holes that match the bolts.

[0010] Furthermore, mounting grooves are provided on both sides of the groove, and the mounting grooves match the mounting plate.

[0011] Furthermore, a sealing cap is attached to the top of the box.

[0012] Furthermore, the inner surface of the first glass plate is coated with a Low-E coating.

[0013] The beneficial effects of this utility model are as follows:

[0014] (1) By setting a desiccant box inside the frame and combining it with a breathable sheet structure, the outside air is dried before entering the hollow cavity, thereby effectively adsorbing the moisture in the gas, maintaining a dry environment inside the cavity, preventing condensation on the inner surface of the glass, and achieving a slow balance of the pressure difference between the inside and outside of the insulating glass through a controllable gas exchange mechanism, reducing the "breathing effect" caused by temperature changes, reducing the risk of sealant fatigue damage, and extending the sealing life of the overall structure.

[0015] (2) By coating the inner surface of the first glass plate with Low-E coating, infrared rays can be effectively reflected, heat transfer can be reduced, the thermal insulation performance of the whole window can be improved, and good visible light transmittance can be maintained at the same time, taking into account both energy saving and lighting needs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4As shown, the insulated glass according to this embodiment of the utility model includes a frame 1. The frame 1 is the basic framework of the entire insulated glass system, responsible for connecting and fixing the first glass panel 2 and the second glass panel 3, and providing installation space for the dehumidification mechanism 5. It is made of corrosion-resistant and high-strength materials such as aluminum alloy or stainless steel to ensure long-term stability and durability. The first glass panel 2 is connected inside the frame 1 and is close to the external environment. The inner surface of the first glass panel 2 is coated with a Low-E coating 13, which is a low-emissivity coating that can effectively reflect infrared rays, reduce heat transfer, and improve heat insulation performance, while maintaining good visible light transmittance. It can serve as the main protective barrier, blocking external wind, rain, and ultraviolet rays to protect the indoor environment. A second glass panel 3 is provided on one side of the first glass panel 2. The second glass panel 3 is connected to the frame 1. A cavity 4 is provided between the first glass panel 2 and the second glass panel 3, which can be filled with an inert gas (such as argon) as needed to further improve the heat insulation and sound insulation effect. The frame 1 contains a dehumidification mechanism 5, which includes a groove 501 inside the frame 1 to accommodate a placement box 502 and its related components. The placement box 502 is slidably connected inside the groove 501. One side of the placement box 502 has a through hole 503 for exchanging and circulating gas with the cavity 4, and the other side has a vent 504 to allow external air to enter the placement box 502. A vent 505, a porous ceramic vent 505, is connected inside the vent 504, providing excellent breathability and selective filtration, effectively blocking dust and moisture while allowing slow air permeation. The outer surface of the vent 505 is covered with a microporous PE film 6 to further enhance waterproofing, prevent dust from clogging the micropores, and extend its service life. The placement box 502 contains a desiccant, including molecular sieves and silica gel, to absorb moisture entering the cavity and maintain a dry environment.

[0025] like Figures 1-4 As shown, a baffle 7 is fixedly connected inside the groove 501, and a sealing gasket is fixedly connected to one side of the baffle 7 to prevent undried gas from directly entering the cavity 4 from the outside of the placement box 502, ensuring that all air entering the cavity is dried. Mounting plates 8 are fixedly connected to both sides of the placement box 502, and the mounting plates 8 are connected to the frame 1 by bolts 9. Mounting plates 8 have mounting holes 10 that match the bolts 9 to fix the placement box 502, ensuring it is securely installed inside the frame 1. Mounting grooves 11 are provided on both sides of the groove 501, and the mounting grooves 11 match the mounting plates 8. A sealing cap 12 is connected to the top of the placement box 502 to seal the top opening of the placement box 502, preventing dust or other impurities from entering.

[0026] In actual use, when the ambient temperature changes, a certain pressure difference will be generated inside and outside the cavity 4, which can easily trigger a "breathing effect," where air repeatedly enters and exits the sealed area due to pressure fluctuations, leading to fatigue and aging of the sealant and a shortened service life. At this time, the dehumidification mechanism 5 located inside the frame 1 begins to function: external air first enters the interior of the placement box 502 through the vent 504 on one side. The vent 504 contains a porous ceramic vent 505, whose microporous structure can effectively block dust, oil, and large water molecules from entering, allowing only slow air permeation. At the same time, the outer surface of the vent 505 is covered with a microporous PE film 6, which further enhances the dustproof and waterproof capabilities, prevents micropore blockage, and extends the service life of the vent 505. The air entering the placement box 502 then passes through the internally filled desiccant (such as molecular sieves or silica gel). These desiccants have a strong moisture absorption capacity and can adsorb the moisture carried in the air, ensuring that the gas output into the cavity 4 is dry gas. The dried air then enters the insulating glass cavity 4 through the through-hole 503 on the other side of the placement box 502, achieving controllable gas exchange and humidity regulation, thereby maintaining a dry environment inside the cavity 4 and preventing condensation or fogging on the inner surface of the glass. Furthermore, when the desiccant needs to be replaced after prolonged use, the placement box 502 can be removed from the groove 501 by disassembling the bolt 9, and the desiccant inside the placement box 502 can be replaced by removing the sealing cap 12.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
