Description

Technical Field

[0001] The utility model belongs to the technical field of doors and windows, and particularly relates to a heat-insulating and energy-saving door and window. Background Art

[0002] At present, with the increasing global attention to energy consumption, green buildings and energy-saving technologies are gradually occupying an important position in the construction industry. Doors and windows are key parts of building envelopes, and their thermal insulation performance is directly related to the overall energy consumption of the building. Therefore, the research and development and application of energy-saving door and window technology is particularly important.

[0003] Energy-saving doors and windows are designed to increase the lighting and ventilation area or to reflect the characteristics of modern buildings. They aim to reduce energy consumption and improve the overall thermal insulation performance of buildings by optimizing door and window design, materials and manufacturing processes. They strictly follow technical standards to ensure that doors and windows meet building energy-saving requirements in terms of thermal insulation, air tightness, ventilation and lighting.

[0004] However, traditional energy-saving doors and windows still have some defects in terms of thermal insulation. For example, the patent specification with publication number CN207905596U discloses a new type of energy-saving, thermal insulation and heat-insulating doors and windows, including a door and window body, which includes profile A, profile B, profile C, profile D, and window frame profile 1; wherein: profile C and profile D form door and window profile 1; profile A and profile B form door and window profile 2; profile B is installed on the right side of profile A; profile B is in an inverted L shape, and profile C is installed on the right side of profile B; profile D is installed on the upper right side of profile C; window frame profile 1 is installed between profile D and the right horizontal part end of profile C; hollow glass plate is installed in window frame profile 1. This type of door and window adopts replacing insulation strips and replacing glass pressure lines to achieve heat insulation effect, but its actual operation is too complicated, requires professional personnel to operate, and increases the user's use cost.

[0005] Through the above analysis, the problems and defects of the existing technology are: traditional energy-saving doors and windows adopt replacement of insulation strips and glass pressure lines to achieve the insulation effect, but the actual operation is too complicated, requiring professional personnel to operate, and increasing the user's cost of use. Utility Model Content

[0006] In order to overcome the problems existing in the related art, the utility model provides a heat-insulating and energy-saving door and window.

[0007] The technical solution of the utility model is as follows:

[0008] A heat-insulating energy-saving door and window is provided with a door and window frame and double-layer glass;

[0009] The door and window frame comprises a longitudinal frame, a transverse frame, a longitudinal stile and a transverse stile, and the double-layer glass is installed on the outside of the door and window frame;

[0010] The outer ends of the longitudinal frame and the transverse frame are provided with fixing grooves, the longitudinal frame, the transverse frame, the longitudinal middle stile and the transverse middle stile are provided with indoor aluminum profiles and outdoor aluminum profiles, a heat insulation strip is sandwiched between the indoor aluminum profile and the outdoor aluminum profile, the middle cavity of the indoor aluminum profile is filled with a heat insulation layer, and the middle cavity of the outdoor aluminum profile is filled with a heat insulation layer;

[0011] A first sealing strip is bonded between the outer side of the outdoor aluminum profile and the double-layer glass, and a first glass glue layer is coated on the outer side of the first sealing strip.

[0012] In one embodiment, a limit plate is provided at the left end of the left longitudinal frame and the lower end of the lower transverse frame of the door and window frame, and a second sealing strip is sandwiched between the limit plate and the double-layer glass.

[0013] In one embodiment, corresponding slots are respectively provided on opposite sides of the indoor aluminum profile and the outdoor aluminum profile, and the thermal insulation strips are installed in the slots.

[0014] In one embodiment, a rubber strip is sandwiched at the middle edge of the double-layer glass, and a second glass glue layer is coated on the outer side of the rubber strip.

[0015] In one embodiment, a plurality of through holes are spaced apart on the inner surface of the rubber strip, and the through holes are filled with desiccant particles.

[0016] In one embodiment, arc-shaped positioning plates are disposed opposite to each other at the inner ends of the indoor aluminum profile and the outdoor aluminum profile of the longitudinal muntin and the transverse muntin.

[0017] In combination with all the above technical solutions, the beneficial effects of the utility model are as follows:

[0018] The utility model sandwiches a heat insulation strip between the indoor aluminum profile and the outdoor aluminum profile, and fills the cavity with a heat insulation layer and a heat insulation layer, so that the doors and windows themselves have effective heat preservation and heat insulation functions, and there is no need to rely on professionals to replace individual accessories, thereby reducing the cost of use. Through the design of double-layer glass, and the heat insulation strips sandwiched between the indoor and outdoor aluminum profiles and the filled heat insulation layer and heat insulation layer, the energy-saving doors and windows significantly improve the heat preservation and heat insulation performance. The double-layer glass and the air layer in the middle can effectively block the conduction of outdoor heat, while the heat insulation strips and the heat insulation layer further reduce the heat exchange between indoor and outdoor, making the indoor temperature more stable and improving the living comfort. Since the energy-saving doors and windows have good heat preservation and heat insulation performance, they can reduce the energy consumption of heating in winter and cooling in summer. This is of great significance for energy conservation and emission reduction, and reducing the energy expenditure of households or enterprises.

[0019] The utility model glues a sealing strip between the outer side of the outdoor aluminum profile and the double-layer glass, which enhances the sealing performance of doors and windows. It can not only prevent problems such as water seepage and air leakage in windy and rainy weather, but also further reduce indoor and outdoor heat exchange and improve the thermal insulation effect.

[0020] The utility model has a simple structure, convenient installation and maintenance, and significant long-term energy-saving effect, so it has a high cost-effectiveness. In summary, this thermal insulation energy-saving door and window brings a better user experience by simplifying the installation and maintenance process, improving the thermal insulation effect, enhancing the sealing performance, and reducing energy consumption.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0028] like Figure 1 As shown, the heat-insulating energy-saving doors and windows provided by the embodiment of the utility model include a door and window frame and double-layer glass. The door and window frame includes a longitudinal frame 1, a transverse frame 2, a longitudinal middle stile 3 and a transverse middle stile 4, and the double-layer glass 5 is installed on the outside of the door and window frame.

[0029] like Figure 2 and Figure 3 As shown, the outer ends of the longitudinal frame 1 and the transverse frame 2 in the embodiment of the utility model are provided with fixing grooves 6, and the longitudinal frame 1, the transverse frame 2, the longitudinal middle stile 3 and the transverse middle stile 4 are all provided with indoor aluminum profiles 7 and outdoor aluminum profiles 8, and a heat insulation strip 9 is sandwiched between the indoor aluminum profile 7 and the outdoor aluminum profile 8, and the middle cavity of the indoor aluminum profile 7 is filled with a heat insulation layer 10, and the middle cavity of the outdoor aluminum profile 8 is filled with a heat insulation layer 11.

[0030] The embodiment of the utility model effectively blocks the direct conduction of indoor and outdoor heat by arranging indoor aluminum profiles 7 and outdoor aluminum profiles 8 in the longitudinal frame 1 and the transverse frame 2 and the longitudinal middle stile 3 and the transverse middle stile 4, and sandwiching a heat insulation strip 9 therebetween. This design significantly reduces the heat conduction coefficient of the door and window, thereby improving the overall heat insulation performance.

[0031] The embodiment of the utility model can further reduce the loss of indoor heat by filling the insulation layer 10 in the middle cavity of the indoor aluminum profile 7, especially in winter, which can keep the indoor warm and improve the living comfort. At the same time, the insulation layer 11 filled in the middle cavity of the outdoor aluminum profile 8 can effectively block the invasion of outdoor heat, further enhancing the insulation effect. By improving the insulation performance and insulation effect, the energy consumption of winter heating and summer cooling can be significantly reduced, thereby reducing the energy expenditure of users. At the same time, it also helps to reduce greenhouse gas emissions and is more environmentally friendly.

[0032] The thermal insulation layer 10 in the embodiment of the utility model refers to a layer of material added in a building or equipment to reduce energy loss and maintain temperature stability. There are many types of materials, including polystyrene foam board EPS and polyurethane foam board PU. The heat insulation layer 11 is a material used to prevent heat transfer, including heat insulation material and heat insulation layer. Heat insulation material is generally fixed on the wall, roof, floor or equipment surface, such as foam plastic, glass wool, rock wool, etc.

[0033] Preferably, a first sealing strip 12 is bonded between the outer side of the outdoor aluminum profile 8 and the double-layer glass 5 in the embodiment of the utility model, and a first glass adhesive layer 13 is coated on the outer side of the first sealing strip 12 .

[0034] The first sealing strip 12 in the embodiment of the utility model is used as the main sealing element between the door and window and the double-layer glass 5, which can effectively prevent outdoor air, water vapor, etc. from penetrating into the room, thereby enhancing the sealing performance of the door and window. This excellent sealing property helps to maintain the stability of the indoor environment and avoid the influence of outdoor bad weather on the indoor environment. Through tight sealing, the first sealing strip 12 reduces the convection of indoor and outdoor air, thereby reducing the efficiency of heat conduction, improving the thermal insulation performance of the door and window, helping to reduce the invasion of outdoor heat in summer, reducing the loss of indoor heat in winter, and improving the comfort of living. At the same time, the first glass glue layer 13 coated on the outside can further protect the sealing strip from the erosion of the external environment and extend its service life. The installation of the first sealing strip 12 and the first glass glue layer 13 is relatively simple, without complicated processes and tools. At the same time, when replacement or maintenance is needed, it can also be easily and quickly disassembled and replaced, reducing maintenance costs.

[0035] Preferably, a limit plate 14 is provided at the left end of the left longitudinal frame 1 and the lower end of the lower transverse frame 2 of the door and window frame in the embodiment of the utility model, and a second sealing strip 15 is sandwiched between the limit plate 14 and the double-layer glass 5.

[0036] In the embodiment of the utility model, the left longitudinal frame 1 and the lower transverse frame 2 are provided with a limit plate 14, so that the edge position of the double-layer glass 5 can be limited when the double-layer glass 5 is installed, thereby ensuring the positioning effect of the double-layer glass 5 and the door and window frame. The first sealing strip 12 and the second sealing strip 15 are usually made of materials with good weather resistance and good elasticity, and can maintain their sealing performance for a long time.

[0037] Preferably, the indoor aluminum profile 7 and the outdoor aluminum profile 8 in the embodiment of the utility model are provided with corresponding slots 16 on opposite sides, and the thermal insulation strip 9 is installed in the slots 16. The embodiment of the utility model limits and fixes the two ends of the thermal insulation strip 9 through the slots 16, which can effectively improve the installation firmness of the thermal insulation strip 9 and ensure sufficient thermal insulation performance.

[0038] Preferably, a rubber strip 17 is sandwiched at the middle edge of the double-layer glass 5 in the embodiment of the utility model, and the outer side of the rubber strip 17 is coated with a second glass glue layer 18. A plurality of through holes are spaced apart on the inner surface of the rubber strip 17, and the through holes are filled with desiccant particles.

[0039] The embodiment of the utility model uses the rubber strip 17 as a sealing element between the double-layer glass 5, which can fit the edge of the double-layer glass tightly and effectively prevent air, water vapor, etc. from penetrating into the cavity between the double-layer glass. This sealing property not only helps to maintain the stability of the internal environment of the double-layer glass, but also prevents the occurrence of condensation and fogging, and improves the thermal insulation performance of doors and windows. Through the sealing effect of the rubber strip 17, the cavity between the double-layer glass 5 can be kept dry and sealed, thereby reducing the convection and heat conduction of indoor and outdoor air, helping to improve the thermal insulation performance of doors and windows, reducing the transmission and loss of energy, and improving the comfort of living. By filling the through hole opened on the inner surface of the rubber strip 17 with desiccant particles, the moisture in the cavity can be absorbed, the humidity can be reduced, and the occurrence of condensation and fogging can be further prevented, which helps to maintain the clarity and transparency of the double-layer glass and improve the visual effect of doors and windows. The use of desiccant particles can keep the cavity between the double-layer glass dry, reduce the erosion of water vapor on glass and sealing materials, help to extend the service life of double-layer glass and doors and windows, and reduce the frequency of maintenance and replacement.

[0040] Preferably, the longitudinal muntin 3 and the transverse muntin 4 in the embodiment of the utility model are provided with arc-shaped positioning plates 19 at both ends of the inner side of the indoor aluminum profile and the outdoor aluminum profile. In the use and application of doors and windows, since the width of the longitudinal muntin 3 and the transverse muntin 4 is larger than the width of the longitudinal frame 1 and the transverse frame 2, the arc-shaped positioning plates 19 can not only fix the heat preservation layer 10 and the heat insulation layer 11 in the cavity, but also improve the structural strength of the longitudinal muntin 3 and the transverse muntin 4.

[0041] The longitudinal frame 1, transverse frame 2, longitudinal stile 3 and transverse stile 4 in the door and window frame of the utility model all adopt the design of indoor aluminum profile 7 and outdoor aluminum profile 8, and a heat insulation strip 9 is sandwiched in the middle. This design effectively cuts off the heat transfer path between the indoor and outdoor aluminum profiles, reduces the thermal conductivity coefficient of the door and window frame, and thus improves the overall heat insulation performance. The heat insulation layer 10 filled in the middle cavity of the indoor aluminum profile 7 can reduce the loss of indoor heat and keep the indoor warm. The heat insulation layer 11 filled in the middle cavity of the outdoor aluminum profile 8 can effectively block the invasion of outdoor heat and enhance the heat preservation effect. The first sealing strip 12 bonded between the outer side of the outdoor aluminum profile 8 and the double-layer glass 5 and the first glass glue layer 13 coated together constitute the first sealing barrier, which effectively prevents the penetration of outdoor air and water vapor. The second sealing strip 15 sandwiched between the stopper plate 14 set at the left end of the left longitudinal frame 1 of the door and window frame and the lower end of the lower transverse frame 2 and the double-layer glass 5 constitutes a second sealing barrier, further enhancing the sealing performance of the door and window. As the main part of the door and window, the air layer formed inside the double-layer glass 5 can effectively prevent the direct transfer of indoor and outdoor heat. The air layer in the middle of the double-layer glass is a poor conductor of heat, so it can significantly reduce the conduction of heat. The desiccant particles filled in the inner through hole of the rubber strip 17 in the middle of the double-layer glass 5 can absorb the water vapor that may be generated between the double-layer glass, keep the internal environment of the double-layer glass dry, and prevent condensation and fogging. The arc positioning plates 19 arranged oppositely at both ends of the indoor aluminum profile and the outdoor aluminum profile of the longitudinal middle stile 3 and the transverse middle stile 4 not only fix the thermal insulation layer 10 and the heat insulation layer 11 in the cavity, but also enhance the structural strength of the middle stile, making it more stable.

[0042] To sum up, the energy-saving doors and windows with thermal insulation provided by the embodiments of the utility model achieve efficient thermal insulation and heat preservation effects through various technical means such as double-layer glass structure, combination of aluminum profiles and insulation strips, filling of thermal insulation layers, multiple sealing structure design and application of desiccant particles, providing users with a more comfortable and energy-saving living environment.
