Description

Technical Field

[0001] The utility model relates to the technical field of door and window structures, and in particular to a low-energy consumption building door and window. Background Art

[0002] Doors and windows are one of the important external protective structures of buildings, playing the role of wind and rain protection, heat insulation, sound insulation, lighting, ventilation, etc. With the improvement of people's living standards and the promotion of environmental protection and energy saving concepts, the requirements for doors and windows in decoration are getting higher and higher, and thermally insulated aluminum doors and windows have begun to be widely used in buildings.

[0003] Thermal break aluminum doors and windows are made of thermal break aluminum profiles and hollow glass, and have the functions of energy saving, sound insulation, noise prevention, dust prevention, waterproofing, etc. There are two main types of thermal insulation profiles currently used. One is to use thermal insulation strip materials and aluminum profiles to form a "thermal insulation bridge" through mechanical toothing, strip insertion, rolling and other processes, which is called "strip insertion" thermal insulation profile; the other is to pour the thermal insulation material into the thermal insulation cavity of the aluminum alloy profile, and after curing, remove the thermal break metal and other processes to form a "thermal insulation bridge", which is called "casting" thermal insulation profile.

[0004] The Chinese invention patent application document with publication number CN113802955A discloses an energy-saving thermally-insulated aluminum door and window, which includes a window frame assembly, the window frame assembly includes a first window frame, a second window frame and a first connecting member for connecting the first window frame and the second window frame, the interior of the first window frame and the interior of the second window frame are both hollow structures and form a first vacuum cavity; a sash frame assembly, the sash frame assembly includes a first sash frame, a second sash frame and a second connecting member for connecting the first sash frame and the second sash frame, the first sash frame is rotatably connected to the first window frame, the interior of the first sash frame and the interior of the second sash frame are both hollow structures and form a second vacuum cavity.

[0005] However, the second connecting member in the above-mentioned energy-saving thermal break aluminum door and window is divided into two parts to realize the two-point connection and fixation of the first window frame and the second window frame. When the solar heat radiates to the first window frame or the second window frame, the first window frame and the second window frame can still be radiated to the middle cavity for heat transfer, and the thermal insulation effect is poor.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0033] The “first” and “second” mentioned in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0034] like Figure 1 and Figure 2 As shown, a low-energy building door and window in one embodiment of the utility model includes a window frame 1 and a window sash 2 arranged on the window frame 1; the window frame 1 includes a first frame body 11, a second frame body 12, and a first connecting rubber strip 13 connecting and separating the first frame body 11 and the second frame body 12; the first connecting rubber strip 13 is provided with a plurality of heat-insulating cavities, and the first connecting rubber strip 13 is respectively connected to the first frame body 11 and the second frame body 12 through a first connecting structure 14, and the first connecting structure 14 includes at least two connecting flanges 141 arranged on both sides of the first connecting rubber strip 13, and connecting grooves 142 arranged on the first frame body 11 and the second frame body 12, and the connecting grooves 142 are adapted to the connecting flanges 141.

[0035] The above-mentioned low-energy building doors and windows connect and separate the first frame 11 and the second frame 12 by setting a first connecting rubber strip 13. When solar heat radiates to the first frame 11 or the second frame 12, the first frame 11 and the second frame 12 are separated by the first connecting rubber strip 13. Heat needs to pass through the first connecting rubber strip 13 and the insulation cavity therein to transfer heat, thereby ensuring the insulation effect. In summer, it can reduce indoor cooling losses.

[0036] In one embodiment, the connection flange 141 is a dovetail flange, and the connection groove 142 is a dovetail groove. Thus, the connection is tight and reliable through the cooperation between the dovetail flange and the dovetail groove.

[0037] In one embodiment, an elastic fastening layer 143 is provided on the outer edge of the connecting flange 141. Thus, when the connecting flange 141 is installed in the connecting groove 142, the elastic fastening layer 143 is pressed to deform and compress it, and after the connecting flange 141 is successfully installed in the connecting groove 142, the elastic fastening layer 143 elastically recovers and contacts with the inner wall of the connecting groove 142 to generate friction, thereby preventing the connecting flange 141 from being displaced in the connecting groove 142 and affecting the connection strength.

[0038] In one embodiment, the window sash 2 includes a third frame 21, a fourth frame 22, and a second connecting rubber strip 23 connecting and separating the third frame 21 and the fourth frame 22; the second connecting rubber strip 23 is provided with a plurality of heat-insulating cavities, and the second connecting rubber strip 23 is respectively connected to the third frame 21 and the fourth frame 22 through a second connecting structure 24. In this way, by providing the second connecting rubber strip 23 to connect and separate the third frame 21 and the fourth frame 22, when solar heat radiates to the third frame 21 or the fourth frame 22, the third frame 21 and the fourth frame 22 are separated by the second connecting rubber strip 23, and the heat needs to pass through the second connecting rubber strip 23 and the heat-insulating cavity therein to be transferred, thereby ensuring the heat insulation effect.

[0039] In one embodiment, a first sealing structure 3 is provided between the window sash 2 and the first frame 11, and a second sealing structure 4 is provided between the window sash 2 and the second frame 12; the first sealing structure 3 includes a first sealing groove 31 provided inside the window sash 2, and a first sealing strip 32 provided on the first frame 11; the second sealing structure 4 includes a second sealing groove 41 provided outside the second frame 12, and a second sealing strip 42 provided on the window sash 2. In this way, the first sealing strip 32 abuts against the first sealing groove 31, and the second sealing strip 42 abuts against the second sealing groove 41, so as to realize a double sealing function, and prevent heat from being directly transferred from the air in the installation gap to the room.

[0040] In one embodiment, a top-sealing rubber strip 16 is further provided on the first connecting rubber strip 13, and a third sealing structure 5 is provided between the top-sealing rubber strip 16 and the window sash 2; the third sealing structure 5 includes a top-sealing flange 51 provided on the top-sealing rubber strip 16, and a top-sealing contact portion 52 provided on the second connecting rubber strip 23. In this way, the top-sealing rubber strip 16 contacts the top-sealing contact portion 52 on the second connecting rubber strip 23, thereby realizing the third sealing function and preventing heat from being directly transferred from the air in the installation gap to the room.

[0041] In one embodiment, a buckle structure 6 is provided at the bottom or top of the window frame 1; the buckle structure 6 comprises a first buckle edge 61 provided on the first frame body 11, a second buckle edge 62 provided on the second frame body 12, and a third buckle edge 63 provided on the first connecting rubber strip 13. Thus, the window frame 1 is installed on the mounting profile by the cooperation of the first buckle edge 61, the second buckle edge 62, and the third buckle edge 63.

[0042] In one embodiment, the window sash 2 further includes a glass body 25 clamped and fixed on the third frame 21 and the fourth frame 22; the glass body 25 is a composite glass structure, including three layers of glass blocks and two filling layers arranged between the glass blocks. In this way, part of the heat can be isolated by the two filling layers, thereby achieving a certain heat insulation effect.

[0043] In one embodiment, the filling layer is a vacuum layer. Thus, the two filling layers between the glass blocks are evacuated to a near vacuum, so that heat conduction is reduced and the heat insulation effect of the entire door and window structure is improved.

[0044] In one embodiment, the first frame 11 and the second frame 12 are both aluminum profiles, and the surface of the aluminum profile is coated with a reflective layer. Specifically, the reflective layer is a reflective surface obtained by sandblasting. In this way, the reflective layer reflects part of the heat radiation, so that the heat accumulated in the first frame 11 or the second frame 12 can be reduced.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
