Description

Technical Field

[0001] The present invention relates to the technical field of doors and windows, and in particular to a high-efficiency cold-insulating and heat-insulating door and window. Background Art

[0002] As the global energy crisis intensifies and low-carbon, environmentally friendly concepts gain widespread adoption, building energy efficiency has become a core indicator of building quality. Doors and windows, as the most active heat exchangers within a building's envelope, have a direct impact on both energy consumption and indoor thermal comfort. Meanwhile, poor insulation can lead to significant indoor temperature fluctuations, making it difficult to maintain a cool environment in the summer and requiring more energy to maintain warmth in the winter. This not only increases the operating costs of air conditioning and heating equipment, but also impacts human comfort due to temperature instability, reducing the quality of living or working.

[0003] Existing high-efficiency heat-insulating doors and windows cannot adjust the angle of the sunshade louvers according to the real-time temperature changes in the area near the multi-layer glass components in the room. When the outside temperature is too high, the sunshade louvers cannot be unfolded to block direct sunlight, causing a large amount of heat to enter the room; when the outside temperature is low, the sunshade louvers cannot be folded up to allow sufficient sunlight to enter, making it difficult to enhance indoor lighting and warming effects, reducing adaptability; and cannot significantly increase the length of the heat transfer path, resulting in an increase in the efficiency of heat conduction through the glass, thereby reducing the basic heat-insulating capacity; at the same time, it cannot buffer the vibration and friction between the glass and the inner frame. After long-term use, the sealing performance is easily degraded due to contact wear, thereby reducing the sealing effect. Summary of the Invention

[0021] Reference Figures 1-6 The present invention provides an embodiment of a high-efficiency heat-insulating door and window, comprising an outer frame 1 and an inner frame 16. The inner frame 16 is internally connected with a multi-layer glass assembly 17 for improving basic heat-insulating and heat-insulating capabilities. The rear end of the outer frame 1 is connected with a heat-insulating adjustment assembly 2 for improving adaptability. The heat insulation adjustment component 2 includes a fixed frame 3, which provides an installation carrier. The front end of the fixed frame 3 is fixedly connected to the rear end of the outer frame 1. Multiple groups of fixed shafts 4 are rotatably connected inside the fixed frame 3. The outsides of the multiple groups of fixed shafts 4 are fixedly sleeved with sunshade blinds 5. By unfolding and retracting to block or accept sunlight, the heat and light entering the room are adjusted.

The controller 12 receives the temperature sensor The sensor 13 receives a signal to control the operation of the motor 8 to realize automatic adjustment of the sunshade blinds 5. The temperature sensor 13 detects the temperature of the indoor area near the glass in real time and provides an adjustment signal to the controller 12. One end of the protective cover 14 is fixedly connected to the outside of the fixed shell 7 by bolts. The protective cover 14 is located outside the motor 8 to protect the motor 8 from external dust, rain and other erosions, thereby extending the service life of the motor 8.

The inner side of the third tempered glass 22 is connected with a transparent conductive film 24, which is electrically connected to the controller 12. When the temperature is low, it is powered on and generates heat to supplement the indoor heat. The first tempered glass 18 and the second tempered glass 20 are separated by the spacer bar 19 to form a first air cavity, and the second tempered glass 20 and the third tempered glass 22 are separated by the spacer bar 21 to form a second air cavity. The first air cavity and the second air cavity are filled with argon to reduce the heat conduction efficiency in the cavity and enhance the cold and heat insulation effect. L-shaped The mounting groove 25 is fixedly connected to the inside of the L-shaped mounting groove 25 with a reinforcing rib 26. The reinforcing rib 26 is in a grid shape, which enhances the load-bearing capacity and overall stability of the four corners of the outer frame 1 and prevents deformation. A sealing groove 27 is provided on the inside of the outer frame 1, and a sealing strip 28 is fixedly connected to the inside of the sealing groove 27. The inside of the sealing strip 28 is fixedly connected to the outside of the inner frame 16. The material of the sealing strip 28 is silicone, which enhances the sealing of the connection between the two and reduces heat loss. A groove 30 is provided on the inside of the inner frame 16. A sealing gasket 31 is fixedly connected to the inside of the groove 30. The inside of the sealing gasket 31 is fixedly connected to the outside of the multi-layer glass assembly 17. The material of the sealing gasket 31 is rubber, which buffers the vibration friction between the multi-layer glass assembly 17 and the inner frame 16 to prevent the seal from failing due to wear.To enhance the sealing performance, a rain shield 32 is fixedly connected to the front end of the outer frame 1 to prevent rainwater from directly contacting the gap of the outer frame 1, reduce rainwater infiltration, and protect the door and window structure.

[0023] Working principle: When the outside temperature is too high, the controller 12 receives the high temperature signal transmitted by the temperature sensor 13 and immediately sends a start command to the motor 8. The motor 8 responds quickly and starts to run. Its output shaft drives the fixed rod 9 to rotate stably inside the fixed shell 7, and the fixed ring 10 outside the fixed rod 9 rotates together. At this time, one end of the connecting rope 6 is wrapped and tightened by the fixed ring 10, and the other end of the connecting rope 6 pulls the sunshade louver 5 through the through hole 11, so that the sunshade louver 5 rotates synchronously around the fixed axis 4 and unfolds until the sunshade louvers 5 are closely arranged to form an effective light-shielding barrier to reduce the heat entering the room; at the same time, the low-emissivity film 23 on the outer surface of the first tempered glass 18 will specifically reflect the infrared rays in the sunlight, further reducing the external heat from entering the room in the form of radiation. The argon gas filled in the first air cavity and the second air cavity effectively blocks the convection transfer of heat between the multi-layer glass components 17 due to its own low thermal conductivity, thereby enhancing the heat insulation effect; When the outside temperature is low, the temperature sensor 13 transmits a low temperature signal to the controller 12, which then controls the motor 8 to rotate in the opposite direction, causing the fixing rod 9 and the fixing ring 10 to move in the opposite direction. The fixing ring 10 pulls the connecting rope 6, and the sunshade louver 5 rotates and retracts around the fixed axis 4, allowing sunlight to enter the room through the multi-layer glass assembly 17, bringing natural light and heat to the room. At the same time, the controller 12 sends a power-on command to the transparent conductive film 24 on the inner side of the third tempered glass 22. When the transparent conductive film 24 is energized, it generates heat, replenishing the indoor heat and maintaining a stable indoor temperature. The sealing strip 28 in the sealing groove 27 inside the outer frame 1 fits tightly between the outer frame 1 and the inner frame 16, effectively filling the tiny gap at the connection between the two and preventing air from convecting and transferring heat through the gap. The sealing gasket 31 in the groove 30 inside the inner frame 16 is in close contact with the outer side of the multi-layer glass assembly 17, which not only buffers the vibration and friction between the two but also further enhances the sealing performance and prevents heat from being lost through the connection between the glass and the frame. In the multi-layer glass assembly 17, the first spacer 19 and the second spacer 21 separate the first tempered glass 18, the second tempered glass 20, and the third tempered glass 22, respectively, forming independent first and second air cavities, further blocking the heat transfer path. The grid-like reinforcement ribs 26 in the L-shaped mounting grooves 25 at the four corners of the outer frame 1 significantly enhance the overall structural strength and deformation resistance of the outer frame 1, ensuring that the doors and windows maintain a stable structure during long-term use or when subjected to external forces; the rain shield 32 at the front end of the outer frame 1 is tilted outward, which can effectively prevent rainwater from directly washing the connection parts and other gaps between the outer frame 1 and the wall, reducing the damage to the door and window components caused by rainwater infiltration; the protective cover 14 on the outside of the fixed shell 7 completely covers the motor 8, preventing external dust, rainwater and other impurities from entering the interior of the motor 8, avoiding the normal operation of the motor 8 due to pollution or moisture, and ensuring the stable operation of the entire adjustment system.
