Description

Technical Field

[0001] This utility model relates to the field of doors and windows, and in particular to a building door and window. Background Technology

[0002] my country's climate is characterized by generally high temperatures in summer, cold and long-lasting winters in the north, and damp and cold winters in the south, though shorter in duration. Except for some extremely cold regions, air conditioning is generally required in summer; in winter, centralized heating is the primary method in the north, while decentralized heating is the main method in the south. The general requirements for doors and windows in Chinese buildings are: maximum heat insulation and heat dissipation in summer, and maximum heat gain and insulation in winter.

[0003] Windows and doors, as relatively vulnerable parts of a building's energy efficiency, account for 40% to 50% of the total energy consumption of the building envelope, bearing a crucial responsibility for building energy conservation. Currently, the industry typically uses low-emissivity (Low-E) glass technology, which reduces the heat transfer coefficient but also lowers the visible light transmittance and solar heat gain coefficient. This means that indoor temperature can only be regulated by adjusting indoor lighting, heating, or cooling, leading to problems such as increased energy consumption for building lighting and heating.

[0004] Some double-glazed windows and doors have appeared on the market. The sash consists of two panes of glass and a roller blind positioned between them. The roller blind is retractable. Therefore, the glass and roller blind are integrated into a single unit; opening and closing the sash involves synchronized movement of both. If the sash is closed and the roller blind is retracted, the two panes of glass still reduce the heat transfer coefficient, visible light transmittance, and solar heat gain coefficient. If the sash is open, it cannot provide insulation or heat preservation for the interior. Therefore, existing windows and doors cannot effectively regulate indoor lighting and temperature according to different seasons and times of day; they can only adjust indoor lighting, heating, or cooling, resulting in high energy consumption for building lighting and heating.

[0019] See Figure 1-4 This utility model discloses a building door and window, including a frame 1 and an inner sash 2, a sunshade 3, and an outer sash 4 installed on the frame 1. The frame 1 includes an inner sash portion 11, a sunshade portion 12, and an outer sash portion 13, which are arranged sequentially from the inside to the outside of the frame 1. Here, "inner side" refers to the side inside the building, and "outer side" refers to the side outside the building.

[0020] The inner fan body 2, the sunshade body 3, and the outer fan body 4 are respectively disposed on the inner fan part 11, the sunshade part 12, and the outer fan part 13, and the inner fan body 2, the sunshade body 3, and the outer fan body 4 are movably connected to the inner fan part 11, the sunshade part 12, and the outer fan part 13, respectively.

[0021] The inner sash, sunshade, and outer sash of this building door and window are all installed on the frame, and are movably connected to the inner sash section, sunshade section, and outer sash section, respectively. This means the inner sash, sunshade, and outer sash can be opened or closed independently without interference or influence. The inner sash, sunshade, and outer sash can be opened or closed according to different seasons and times of day to adjust indoor lighting and temperature, meeting the needs for heat preservation, insulation, and lighting in different seasons and at different times of day, effectively saving energy for lighting, heating, or cooling.

[0022] It should be noted that the inner fan body 2 and the inner fan section 11 are both located indoors, while the outer fan body 4 and the outer fan section 13 are both located outdoors.

[0023] Specifically, such as Figure 1-2 As shown in Figure 4, the inner fan body 2 includes an inner fan frame 21 and an inner fan component 22 mounted on the inner fan frame 21. The inner fan frame 21 and the inner fan portion 11 are movably connected. The inner fan component 22 is made of glass. The inner fan frame 21 is made of aluminum alloy. The connection between the inner fan frame 21 and the inner fan portion 11 is located on the side of the inner fan frame 21 and the inner fan portion 11, facilitating the opening of the inner fan body into the room.

[0024] Preferably, the inner fan body 2 and the inner fan section 11 are hinged, with the hinge point located on the side frame strip of the inner fan frame 21 and the inner fan section 11, allowing the inner fan body to be fully opened into the room without occupying too much indoor space. More preferably, the inner fan body and the inner fan section are hinged by a hinge, but this is not a limitation.

[0025] Preferably, such as Figure 1-2 As shown in Figure 4, the inner fan frame 2 and the inner fan part 11 abut against each other through the first inner fan contact 23 and the second inner fan contact 24. The first inner fan contact 23 is located on the side of the inner fan frame 2 and the inner fan part 11 near the sunshade part 12, and the second inner fan contact 24 is located on the side of the inner fan frame 2 and the inner fan part 11 away from the sunshade part 12. The width of the first inner fan contact 23 is smaller than the width of the second inner fan contact 24.

[0026] When the inner fan body is closed, its two sides abut against the inner fan section. Both the first and second inner fan contacts are circumferentially arranged around the inner fan body. The width of the first inner fan contact is smaller than the width of the second inner fan contact, which not only limits the movement of the inner fan body but also allows for better cooperation between the inner fan body and the inner fan section, ensuring complete closure of the inner fan section. Both the first and second inner fan contacts refer to the positions where the inner fan frame and the inner fan section contact each other.

[0027] More preferably, both the first inner fan contact 23 and the second inner fan contact 24 are provided with adhesive strips (not shown in the figure). The adhesive strips not only serve as a buffer to avoid large impacts between the inner fan body and the inner fan section, but also serve as a seal to prevent the exchange of indoor and outdoor air or the entry and exit of foreign objects.

[0028] Specifically, such as Figure 1-2 As shown in Figure 4, the outer fan body 4 includes an outer fan frame 41 and an outer fan component 42 mounted on the outer fan frame 41. The outer fan frame 41 and the outer fan section 13 are movably connected. The outer fan component 42 is made of glass. The outer fan frame 41 is made of aluminum alloy. The connection between the outer fan frame 41 and the outer fan section 42 is located at the upper and lower ends of the outer fan frame 41 and the outer fan section 42, making it convenient for the user to open the outer fan body to the outside.

[0029] Preferably, the outer fan body 4 and the outer fan section 13 are hinged, with the hinge point located on the upper and lower frame bars of the outer fan frame 41 and the outer fan section 13. The outer fan body can rotate around the hinge axis, thereby allowing the outer fan body to open or close. The outer fan body only opens to the outside.

[0030] Preferably, such as Figure 1-2 As shown in Figure 4, the outer fan frame 41 and the outer fan part 13 abut against each other through the first outer fan contact 43 and the second outer fan contact 44. The first outer fan contact 43 is located on the side of the outer fan frame 41 and the outer fan part 13 close to the sunshade part 12, and the second outer fan contact 44 is located on the side of the outer fan frame 41 and the outer fan part 13 away from the sunshade part 12. The width of the first outer fan contact 43 is smaller than the width of the second outer fan contact 44.

[0031] When the outer fan body is closed, its two sides abut against the outer fan section. Both the first and second outer fan contacts are circumferentially arranged around the outer fan body. The width of the first outer fan contact is smaller than the width of the second outer fan contact, which not only limits the movement of the outer fan body but also allows for better cooperation between the outer fan body and the outer fan section, ensuring complete closure of the outer fan section. Both the first and second outer fan contacts refer to the positions where the outer fan frame and the fan section contact each other.

[0032] More preferably, both the first outer fan contact 43 and the second outer fan contact 44 are provided with adhesive strips (not shown in the figure). The adhesive strips not only serve as a buffer to avoid large impacts between the outer fan body and the outer fan section, but also serve as a seal to prevent the exchange of indoor and outdoor air or the entry and exit of foreign objects.

[0033] Preferably, such as Figure 1 As shown, the frame 1, inner fan 2, and outer fan 4 are all filled with insulation components 5. The insulation components reduce heat exchange between the indoor and outdoor spaces, thus providing thermal insulation.

[0034] More preferably, the insulation element 5 is insulation cotton or aerogel, but is not limited thereto.

[0035] Preferably, the outer periphery of the inner fan frame 21 and the inner periphery of the inner fan part 11 are provided with adhesive strips (not shown in the figure). The two adhesive strips abut against each other when the inner fan body is closed, which further plays a role in sealing and heat preservation.

[0036] It should be noted that the aforementioned "rubber strip" is made of rubber or silicone, but is not limited to these.

[0037] Preferably, such as Figure 2 , 4 As shown, the inner fan body 2 is provided with an inner fan handle 25, which is located on the side away from the sunshade body 3; the outer fan body 4 is provided with an outer fan handle 45, which is located on the side closer to the sunshade body 3. The inner and outer fan handles are designed to allow users to easily grip and push the inner and outer fan bodies to open or close them.

[0038] Preferably, the sunshade body 3 is a sunshade roll film, which can be rolled up or down. The rolling up or down of the sunshade roll film can be achieved manually or mechanically. Manual operation can be achieved by pulling the curtain strip, while mechanical operation can be achieved by a motor drive. Specifically, the manual and mechanical structures can adopt existing technical structures, which will not be described in detail here.

[0039] This utility model of building doors and windows can achieve multiple usage states: like Figure 2 As shown, when the outdoor temperature is low at night in winter, both the inner fan 2 and the outer fan 4 are closed and the sunshade 3 is retracted, which can prevent indoor heat from being lost to the outside through the windows, so as to achieve the maximum heat preservation effect.

[0040] like Figure 3 As shown, when there is sunshine during the day in winter and the outdoor temperature is higher than the indoor temperature, by opening the inner fan 2, closing the outer fan 4, and retracting the sunshade 3, solar heat can be transferred into the room, while blocking cold outdoor winds from entering the room, ensuring a comfortable indoor temperature.

[0041] like Figure 4 As shown, when the outdoor temperature is high and the sun is shining directly in the summer, by simultaneously closing the inner fan 2 and the outer fan 4 and lowering the sunshade 3, outdoor heat can be blocked from entering the room through the window to the greatest extent, thus saving air conditioning energy consumption.

[0042] Therefore, the building doors and windows of this utility model can open or close the inner sash, sunshade and outer sash according to different seasons and times of day to adjust indoor lighting and temperature, so as to meet the needs of heat preservation, heat insulation and lighting in different seasons and times of day, and can effectively save lighting, heating or cooling energy.

[0043] In summary, this utility model provides a building door and window, in which each part can be opened or closed independently to adjust indoor lighting and temperature according to different seasons and times of day.

[0044] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
