Description

Technical Field

[0002] As a crucial component of a building's external envelope, the performance of doors and windows directly impacts a building's energy efficiency, indoor comfort, and lifespan. In recent years, with the promotion of energy conservation and environmental protection concepts, the sealing performance of doors and windows has become a core focus in design and manufacturing. Currently, most door and window products improve sealing by increasing the number of sealing strips, optimizing profile structure, or using multi-layered glass to reduce heat loss, provide sound insulation and noise reduction, and offer dust and water resistance. However, this approach fails to dynamically adjust the sealing effect according to seasonal changes (such as winter insulation and summer ventilation), differences in indoor and outdoor environments (such as temperature and humidity), or building type (such as residential ventilation needs and industrial plant dust control requirements), resulting in energy waste and decreased comfort.

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0020] This application provides a sliding energy-saving door and window system, which solves the technical problem of insufficient adaptive adjustment capability of existing door and window systems.

[0021] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows: like Figures 1-8 As shown, this invention discloses a sliding energy-saving door and window system, including an outer frame 10 and an inner frame 20. Both the outer frame 10 and the inner frame 20 are made of high-strength thermally insulated aluminum alloy profiles or thermally broken aluminum profiles, possessing good mechanical strength, corrosion resistance, and low thermal conductivity. The outer frame 10 is installed in the door and window openings of the building wall and is securely connected by expansion bolts or special connectors. A waterproof sealant layer is provided on the contact surface to prevent water seepage. The inner ring of the outer frame 10 is provided with a first groove 11, and the inner frame 20 is pressed or snap-fitted into the first groove 11. After installation, it forms a continuous shape with the outer frame 10. For a stationary, immovable fixed connection, after the inner frame 20 and the outer frame 10 are installed and fixed, there is a preset ventilation gap between them along the circumference. A window is installed in the inner frame 20. The inner wall of the first groove 11 is sealed with a flexible heat insulation layer 12. The outer ring of the inner frame 20 is provided with a second groove 21. The second groove 21 is embedded with an annular heat insulation strip 22. A third groove 23 is opened in the circumference of the outer ring of the annular heat insulation strip 22. An electromagnet 24 is embedded in the third groove 23. A magnetic adsorption block 13 is fixedly provided on the inner wall of the flexible heat insulation layer 12. The electromagnet 24 and the operating ground attract the magnetic adsorption block 13.

[0022] The inner wall of the first groove 11 is sealed with a flexible heat insulation layer 12 by adhesive or snap-fit. The material is preferably polyurethane foam, EPDM rubber or silicone, with a thickness of 2-5mm. The annular heat insulation strip 22 is made of rigid polyurethane foam, phenolic foam or vacuum insulation board material. The third groove 23 is embedded with a flexible coil or sheet electromagnet 24. The electromagnet 24 is continuously arranged along the circumference or set in segments, such as a segment on each side of the third groove 23. It is connected to the low-voltage DC power supply 25 in the door and window frame through wires. The magnetic adsorption block 13 is made of soft iron, low carbon steel or ferrite magnetic material, and the surface is galvanized or sprayed with anti-rust treatment to ensure long-term adsorption reliability.

[0023] The electromagnet 24 is connected to the controller via wires. Additionally, a temperature and humidity sensor, an air quality sensor, or a timing module can be added. When the temperature, humidity, air quality, or time reaches preset values, the controller activates the electromagnet 24, achieving automatic control. The controller's control of the electromagnet's strength based on parameters detected by the temperature and humidity sensor, air quality sensor, or timing module is existing technology; the process of how the controller controls the electromagnet through sensor parameters will not be elaborated here. For example, it can automatically energize to enhance sealing in low-temperature winter conditions and de-energize to promote natural ventilation in high-temperature and high-humidity summer conditions. It can also automatically de-energize to promote natural ventilation when indoor air quality is poor, without the resident's knowledge.

[0024] By setting a matching electromagnet 24 and a magnetic adsorption block 13 between the outer frame 10 and the inner frame 20, and combining the flexible heat insulation layer 12 and the annular heat insulation strip 22, the relative position of the electromagnet 24 and the magnetic adsorption block 13 is controlled by increasing the attraction force of the electromagnet 24. This ultimately achieves the distance between the flexible heat insulation layer 12 and the annular heat insulation strip 22, thereby controlling the temperature and air exchange between the inside and outside of the door and window system, allowing the door and window system to adapt to different environments.

[0025] Specifically, when a high level of sealing is required at night, in winter, or when there is a lot of outdoor noise, the user operates the switch to energize the electromagnet 24, which generates a magnetic field that strongly attracts the magnetic adsorption block 13, causing the flexible insulation layer 12 to tighten inward. This causes the flexible insulation layer 12 to deform under pressure and fit tightly against the annular insulation strip 22, forming multiple barriers that are airtight, watertight, and soundtight.

[0026] When ventilation is required or the sealing level is reduced, the power supply to the electromagnet 24 is cut off, the magnetic field disappears, and the flexible insulation layer 12 and the annular insulation strip 22 are in a loose fit state, allowing air circulation.

[0027] Furthermore, the strength of the electromagnet 24 can be controlled. Since the flexible insulation layer 12 has a certain elasticity, the attraction force of the electromagnet 24 and the elastic force of the flexible insulation layer 12 can be adjusted, so that the relative position between the flexible insulation layer 12 and the annular insulation strip 22 can be adjusted, and the ventilation status of the door and window system can be adjusted in multiple positions.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] like Figure 2As shown, a plurality of memory alloy springs 14 are fixedly arranged in the inner circumference of the first groove 11. Preferably, 6-12 memory alloy springs 14 are arranged on each side of the outer frame 10. The memory alloy springs 14 are made of nickel-titanium memory alloy material. One end of the memory alloy spring 14 is fixedly connected to the bottom of the first groove 11, and the other end of the memory alloy spring 14 is fixedly connected to the magnetic adsorption block 13.

[0030] At room temperature, such as below 20°C, the shape memory alloy spring 14 is in the "low-temperature martensitic phase," possessing excellent flexibility and deformability, and is easily compressed. The attraction of the electromagnet 24 more easily overcomes the elastic force of the shape memory alloy spring 14, allowing the flexible insulation layer 12 and the annular insulation strip 22 to be tightly sealed. When heated by electricity or when the ambient temperature rises above the phase transformation point, it transforms into the "high-temperature austenitic phase," restoring its preset shape and generating restoring force. At this time, the electromagnet 24 does not work, and the shape memory alloy spring 14 contracts to its initial state. The shape memory alloy spring 14 pulls the flexible insulation layer 12 towards the outside of the outer frame 10, further expanding the distance between the flexible insulation layer 12 and the annular insulation strip 22, automatically opening the ventilation channel, realizing passive micro-ventilation without the need for mechanical window opening, effectively regulating indoor air quality, and preventing condensation and energy waste.

[0031] Preferred, such as Figure 3 , Figure 4 As shown, ventilation holes 15 are provided on the side of the outer frame 10. The number of ventilation holes 15 can be one or more, and they can be provided on one or more sides of the outer frame 10. It is preferable that the ventilation holes 15 are provided on both the outer and inner sides of the outer frame 10 to allow for smoother air flow. A filter screen 16 is insulated and embedded in the outer frame 10 and the ventilation holes 15 to prevent the filter screen 16 from conducting electricity with the outer frame 10 and the inner frame 20. The filter screen 16 is made of stainless steel perforated mesh or stainless steel wire woven mesh. A DC power supply 25 is fixedly installed in the second groove 21. The positive and negative terminals of the DC power supply 25 are connected to the two ends of the filter screen 16 through insulated wires. The DC power supply 25 is preferably 12V or 24V, so that the filter screen 16 is charged when energized, forming an electrostatic adsorption layer. When air flows through the filter screen 16, suspended particles are polarized by electrostatic induction and adsorbed onto the surface of the filter screen 16, realizing active electrostatic dust removal and significantly improving air purification efficiency.

[0032] Furthermore, such as Figure 3 , Figure 4As shown, a piezoelectric sheet 17 is fixedly disposed on the filter screen 16. The piezoelectric sheet 17 is a piezoelectric ceramic sheet and is disposed around the filter screen 16. The piezoelectric sheet 17 is fixed to the filter screen 16 by conductive adhesive or micro-welding. An AC power supply 26 is fixedly disposed in the second groove 21. The piezoelectric sheet 17 and the AC power supply 26 are connected by wires. The wires of the DC power supply 25 and the AC power supply 26 are embedded in the inner frame 20 to avoid affecting the sealing effect between the flexible heat insulation layer 12 and the annular heat insulation strip 22.

[0033] After the filter 16 has been used for a period of time, turn off the DC power supply 25 and turn on the AC power supply 26. The piezoelectric sheet 17 generates high-frequency vibration under the action of the AC electric field, causing the particulate matter adsorbed on the surface of the filter 16 to fall off, realizing automatic cleaning, extending the service life of the filter 16, and ensuring continuous and efficient air purification effect.

[0034] A dust collection box 18 is fixedly installed on the outer side of the outer frame 10. The dust collection box 18 is located below the filter screen 16 and is used to collect particles that are shaken off the filter screen 16.

[0035] Preferred, such as Figures 3-7 As shown, the door and window system also includes a dust removal mechanism 30, which includes: The air pump 31 is a miniature manual or semi-automatic piston air pump. The air pump 31 is fixedly mounted on the outer frame 10, and the outer frame 10 is provided with a slide rail 32. The piston rod of the air pump 31 is slidably mounted in the slide rail 32 via a slider 33. The slide rail 32 has a "T" shaped or dovetail groove structure to ensure that the piston rod is stable and without deflection when it moves in a straight reciprocating motion. The user moves the piston rod by pushing or pulling the handle or by moving the window sash. The piston rod moving in conjunction with the window sash is a multi-link mechanism, which is already maturely used in the door and window industry and will not be described in detail here. This drives the piston rod to slide in the slide rail 32 to realize manual inflation operation; it can also be designed to be driven by an electric push rod to realize automatic control.

[0036] The airbag 34 is made of a flexible material with good elasticity and high pressure resistance, such as silicone or TPU. The airbag 34 is set in the inner frame 20. The air inlet of the airbag 34 is connected to the air outlet of the air pump 31 through a pipeline. A one-way valve is installed in the pipeline between the airbag 34 and the air pump 31. The air outlet of the airbag 34 is connected to a Venturi tube 35, which is oriented towards the ventilation hole 15. A solenoid valve is connected between the airbag 34 and the Venturi tube 35. The solenoid valve is normally closed to prevent the airbag 34 from leaking. When dust removal is required, the controller sends a signal to open it instantly, and the compressed gas in the airbag 34 is rapidly released, forming a high-speed airflow that is ejected through the Venturi tube 35.

[0037] When filter 16 accumulates a lot of dust, the user can push the piston rod of air pump 31 back and forth several times, or open the window to activate the piston, forcing air into air bag 34 and storing it. When cleaning is needed, the controller opens the solenoid valve, which releases the compressed gas in air bag 34 quickly, forming a strong airflow that blows off stubborn particles on filter 16, effectively preventing filter 16 from clogging and maintaining ventilation efficiency. The design of venturi tube 35 further amplifies the airflow speed and improves the cleaning effect.

[0038] Furthermore, the Venturi tube 35 is connected to a flow guide shroud 36, which is located at the ventilation hole 15. One end of the flow guide shroud 36 is fixedly connected to the outlet end of the Venturi tube 35 by means of threads, snaps, or adhesive to ensure seamless airflow. The other end extends toward the ventilation hole 15 and is precisely aligned with the surface of the filter screen 16 to form a concentrated directional blowing channel. The flow guide shroud 36 and the filter screen 16 are spaced apart to avoid affecting the airflow between the outer frame 10 and the inner frame 20 through the ventilation hole 15. The inner wall of the flow guide shroud 36 is smooth and has a tapered or streamlined design to further focus the high-speed airflow and improve the impact force on the surface of the filter screen 16 and the dust removal efficiency.

[0039] The air guide shroud 36 has a longitudinal elongated hole along its axis at its lowest point, which facilitates the discharge of heavy impurities. The elongated hole is connected to a vertical pipe 37, which connects to the outside of the outer frame 10. The vertical pipe 37 is made of PVC or ABS, forming a closed dust discharge channel to ensure that the blown dust is discharged directly outdoors, avoiding accumulation between the outer frame 10 and the inner frame 20, which could cause secondary pollution or blockage.

[0040] When the venturi tube 35 ejects a high-speed airflow to clean the dust, some dust is re-detached from the surface of the filter screen 16 by the external force, some dust is detached from the surface of the filter screen 16 by impact, or dust is detached from the surface of the filter screen 16 by the vibration of the piezoelectric plate 17. The dust falls into the bottom of the guide shroud 36 under the action of gravity, and is guided by the elongated hole to fall vertically along the vertical pipe 37, and finally falls into the dust collection box 18, effectively preventing dust from accumulating between the outer frame 10 and the inner frame 20 and causing secondary pollution or blockage.

[0041] Preferred, such as Figures 3-7As shown, the airbag 34 is provided with a spiral tube 38 on the outside. One end of the spiral tube 38 is connected to the air outlet of the air pump 31, and the other end of the spiral tube 38 is connected to the air inlet of the airbag 34. The spiral tube 38 increases the travel distance of air in the inner frame 20, prolongs the heat exchange between the indoor hot air and the inner frame 20, raises the temperature between the inner frame 20 and the window sash, reduces the possibility of freezing between the window sash and the inner frame 20, and also protects the airbag 34. The Venturi tube 35 is provided with fins 39 on the outside. The fins 39 extend along the axial direction of the Venturi tube 35, cover the throat of the Venturi tube 35, increase the heat dissipation area on the outer surface, and improve the heat conduction efficiency.

[0042] By installing a spiral tube 38 on the outside of the airbag 34 and adding fins 39 on the outside of the venturi tube 35, the spiral tube 38, which serves as an air channel connecting the air pump 31 and the airbag 34, is spirally wound around the surface of the airbag 34. This effectively extends the airflow path, achieving buffering and pressure stabilization, reducing pulsation, and ensuring uniform inflation. At the same time, it increases the air travel distance in the inner frame 20, prolonging the heat exchange between the indoor hot air and the inner frame 20, raising the temperature between the inner frame 20 and the window sash, and reducing the possibility of freezing between the window sash and the inner frame 20. The metal fins 39 installed on the outer wall of the venturi tube 35 significantly increase the heat dissipation area, further transferring heat to the inner frame 20, preventing freezing between the window sash and the inner frame 20 in winter, and ensuring the normal opening and closing of the window sash. Each dust cleaning operation is a "micro-heating" process, and multiple operations can accumulate to maintain the local temperature of the inner frame 20 above the dew point, achieving anti-freeze self-protection.

[0043] Although preferred embodiments of the invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the invention.

[0044] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
