Description

Technical Field

[0001] The present invention relates to the technical field of door and window structures, and more particularly, to a heat insulation structure. Background Art

[0002] Doors and windows, as part of a building, mainly function for ventilation, air permeability and lighting. Moreover, for modern buildings, doors and windows also have a decorative function. However, current windows are mainly aluminum alloy doors and windows. The window frames are generally integrated aluminum alloy window frames, and the window panes are aluminum alloy window panes. Since aluminum alloy has good thermal conductivity, in winter, the lower outside temperature is transmitted into the room through the doors and windows, resulting in a lower indoor temperature. In summer, the higher outside temperature is transmitted out of the room through the doors and windows, resulting in a higher outside temperature. The heat insulation effect of the windows is poor, affecting the living comfort.

[0003] And because the aluminum alloy frame has strong heat conduction ability, heat insulation is required during the production of aluminum alloy doors and windows. The existing heat insulation structures of doors and windows usually use heat insulation strips to insulate the aluminum alloy frames. Traditional aluminum alloy doors and windows avoid direct contact of the aluminum alloy frames for heat transfer through the connection sequence of the inner frame, heat insulation strips and outer frame. The heat insulation strips are usually arranged in a form of multiple horizontal rows in parallel.

[0004] However, although there is no direct contact between the inner and outer frames of the aluminum alloy, heat can still be transferred through the air, and the heat insulation effect is poor. The outside temperature can easily affect the indoor temperature of the house, thus reducing the living comfort. Summary of the Invention

[0005] Based on this, in order to solve the problem that the heat insulation structure uses multiple heat insulation strips arranged horizontally in parallel for heat insulation, and the heat insulation effect is poor due to heat transfer through the air by the aluminum alloy frame, the present invention provides a heat insulation structure, and its specific technical solution is as follows:

[0006] A heat insulation structure includes a window frame, a window sash and a transition material assembly. The window frame includes an inner frame, an outer frame and a sealing unit; a plurality of sealing grooves are provided on the window sash, and matching heat insulation rubber strips are provided on the sealing grooves; the transition material assembly is clamped on the window frame; when the heat insulation rubber strip abuts against the window frame, it is in close contact with the transition material assembly through elastic deformation; the sealing unit includes a first heat insulation strip, and a plurality of heat insulation cavities are provided in the first heat insulation strip; the inner frame and the outer frame are connected by the first heat insulation strip.

[0007] The above heat insulation structure enables a good heat insulation structure to be formed between the window frame and the window sash in the closed state by means of the heat insulation rubber strip of the window sash abutting against the adapter component arranged on the window frame. In addition, the inner frame and the outer frame are connected into the window frame by the first heat insulation strip, and then the heat transferred between the inner frame and the outer frame is reduced by a plurality of heat insulation cavities in the first heat insulation strip. Among them, each heat insulation cavity is a heat insulation small unit, and each heat insulation small unit absorbs and attenuates the conducted heat, so as to avoid the aluminum alloy frame body transferring heat through the air and further improve the heat insulation effect.

[0008] Further, the first heat insulation strip is a honeycomb heat insulation strip, and the heat insulation cavity is a regular hexagon cavity.

[0009] Further, the adapter component includes a heat insulation unit arranged above the first heat insulation strip. The heat insulation unit includes a partition rubber strip and a drainage rubber strip group arranged on the window sash. The drainage rubber strip group is provided with drainage holes for draining water. The partition rubber strip is adapted to the drainage rubber strip group.

[0010] Further, the drainage rubber strip group includes a blade frame strip and a leaf-shaped rubber strip. The blade frame strip is provided with an anti-backflow cavity communicating with the drainage holes, and a fastening groove is arranged in the anti-backflow cavity. The leaf-shaped rubber strip is provided with a fastening part and an abutting blade. The leaf-shaped rubber strip is connected to the fastening groove through the fastening part, so that the abutting blade can rotate relative to the blade frame strip and realize the switching between the communication state and the closed state of the drainage holes.

[0011] Further, the abutting blade is provided with at least two blade bodies.

[0012] Further, the hardness of the partition rubber strip is less than that of the drainage rubber strip group.

[0013] Further, the blade frame strip is provided with a plurality of deformation cavities.

[0014] Further, the window sash includes an inner sash frame, an outer sash frame and a second heat insulation strip. The inner sash frame and the outer sash frame are connected by the second heat insulation strip. The second heat insulation strip is provided with a clamping groove, and the partition rubber strip is provided with a first clamping flange adapted to the clamping groove.

[0015] Further, an installation gap is formed between the window frame and the window sash. The partition rubber strip divides the installation gap into a first space and a second space by abutting against the drainage rubber strip group. A drainage cavity is arranged between the window frame and the adapter component, and the drainage cavity is communicated with the drainage holes.

[0016] Further, the heat insulation structure further includes a filling unit, and the filling unit is arranged in a second installation groove between the adapter component and the window frame. Description of the Drawings

[0044] In the present invention, "first" and "second" do not represent specific quantities and sequences, but are only used for name distinction.

[0045] Such as Figure 1 And Figure 2 、 Figure 5As shown in the figure, a heat insulation structure in an embodiment of the present invention includes a window frame 1, a window sash 2, and a transition material component 3. The window frame 1 includes an inner frame 11, an outer frame 12, and a sealing unit 13. A number of sealing grooves 21 are provided on the window sash 2, and a matching heat insulation rubber strip 22 is provided on the sealing grooves 21. The transition material component 3 is snap-connected to the window frame 1. When the heat insulation rubber strip 22 abuts against the window frame 1, it is in close contact with the transition material component 3 through elastic deformation. The sealing unit 13 includes a first heat insulation strip 131, and a number of heat insulation cavities 1311 are provided inside the first heat insulation strip 131. The inner frame 11 and the outer frame 12 are connected by the first heat insulation strip 131.

[0046] For the above heat insulation structure, the heat insulation rubber strip 22 of the window sash 2 abuts against the transition material component 3 provided on the window frame 1, so as to form a good heat insulation structure between the window frame 1 and the window sash 2 in the closed state. In addition, the inner frame 11 and the outer frame 12 are connected into the window frame 1 through the first heat insulation strip 131, and then the heat transfer between the inner frame 11 and the outer frame 12 is reduced by a number of heat insulation cavities 1311 inside the first heat insulation strip 131. Among them, each heat insulation cavity 1311 is a heat insulation small unit, and each heat insulation small unit absorbs and attenuates the conducted heat, so as to avoid the aluminum alloy frame transferring heat through the air and further improve the heat insulation effect.

[0047] In one embodiment, a drainage channel is provided inside the transition material component 3. Since most of the heat insulation strips and sealing strips in the existing doors and windows are made of rubber materials, due to the characteristics of thermal expansion and contraction of rubber materials, the heat insulation strips and sealing strips will contract when the outdoor temperature is low, resulting in rainwater leaking into the doors and windows from the gaps and causing water accumulation inside the doors and windows. Thus, by providing a drainage channel to discharge the rainwater, the service life of the heat insulation strips and sealing strips is prevented from being reduced due to being soaked by rainwater.

[0048] In one embodiment, the first heat insulation strip 131 is a honeycomb heat insulation strip, and the heat insulation cavity 1311 is a complete regular hexagon cavity or a partial shape cavity of a regular hexagon. Thus, by setting the first heat insulation strip 131 as a honeycomb heat insulation strip, the regular hexagon heat insulation cavity structure is simple, has good supporting force, and is convenient for connecting the inner frame 11 and the outer frame 12 into the window frame 1.

[0049] Such as Figure 6 and Figure 7As shown, in one embodiment, the adapter component 3 includes a heat insulation unit disposed above the first heat insulation strip 131. The heat insulation unit includes a partition rubber strip 23 disposed on the window sash 2 and a drainage rubber strip group 32. The drainage rubber strip group 32 is provided with drainage holes for draining water. The partition rubber strip 23 is adapted to the drainage rubber strip group 32. In this way, when the window sash 2 approaches the window frame 1, by providing the partition rubber strip 23 to press against the drainage rubber strip group 32, a sealing structure with waterproof and heat insulation effects is formed, so that the water liquid cannot backflow into the house from the fitting gap between the window sash 2 and the window frame 1, thereby avoiding water seepage of the doors and windows due to rainwater backflow on rainy days.

[0050] As Figure 6 and Figure 7 As shown, in one embodiment, the drainage rubber strip group 32 includes a blade frame strip 321 and a leaf-shaped rubber strip 322. The blade frame strip 321 is provided with an anti-backflow cavity 320 communicating with the drainage holes. The anti-backflow cavity 320 is provided with a fastening groove 3211 and a limiting portion 3212. The leaf-shaped rubber strip 322 is provided with a fastening portion 3221 and an abutting blade 3222. The leaf-shaped rubber strip 322 is connected to the fastening groove 3211 through the fastening portion 3221, so that the abutting blade 3222 can rotate relative to the blade frame strip 321 and realize the switching between the communication state and the closed state of the drainage holes. Specifically, the drainage holes are channels penetrating the blade frame strip 321. In this way, under the action of wind pressure, the abutting blade 3222 of the leaf-shaped rubber strip 322 is pressed against the limiting portion 3212 in the anti-backflow cavity 320, so that the anti-backflow cavity 320 is divided into multiple closed cavities, thereby realizing the closed state of the drainage holes. When rainwater leaks into the inner cavity of the isobaric rubber strip, that is, the installation gap, the rainwater can flow downward through the drainage holes opened on the blade frame strip 321 to the anti-backflow cavity 320. When the weight of the rainwater exceeds the wind pressure, the leaf-shaped rubber strip 322 can rotate with the fastening portion 3221 as the center, so that the drainage holes are in a communicating state, and then the rainwater can flow through the anti-backflow cavity 320 and be discharged outdoors.

[0051] In one embodiment, the abutting blade 3222 is provided with at least two leaf bodies. In this way, by providing at least two leaf bodies on the abutting blade 3222, the abutting blade 3222 divides the anti-backflow cavity 320 into at least three cavities, which is convenient for the leaf bodies to abut against the limiting portion 3212 in sequence under the action of wind pressure. By the close contact between the leaf bodies and the limiting portion 3212, the drainage rubber strip group 32 is ensured to have good waterproof performance, airtight performance and heat insulation performance.

[0052] In one embodiment, the hardness of the partition rubber strip 23 is less than that of the drainage rubber strip group 32. In this way, when the partition rubber strip 23 abuts against the drainage rubber strip group 32, the partition rubber strip 23 deforms preferentially, thereby preventing the drainage rubber strip group 32 from deforming too much and causing the anti-backflow cavity 320 to deform, resulting in the inability of the leaf-shaped rubber strip 322 to rotate, and thus the drainage hole cannot switch between the communication state and the closed state.

[0053] In one embodiment, the blade frame strip 321 is provided with a plurality of deformation cavities. In this way, by providing a plurality of deformation cavities, a deformation space is left for the drainage rubber strip group 32, so as to ensure that when the anti-backflow cavity 320 deforms, the leaf-shaped rubber strip 322 can still rotate to switch the drainage hole between the communication state and the closed state.

[0054] As Figure 2 and Figure 3 As shown, in one embodiment, the window sash 2 includes an inner sash frame 25, an outer sash frame 26 and a second heat insulation strip 27. The inner sash frame 25 and the outer sash frame 26 are connected by the second heat insulation strip 27; the second heat insulation strip 27 is provided with a clamping groove 271, and the partition rubber strip 23 is provided with a first clamping flange 231 adapted to the clamping groove 271. In this way, by clamping the first clamping flange 231 into the clamping groove 271, the partition rubber strip 23 is clamped onto the second heat insulation strip 27, thereby realizing detachable connection. The partition rubber strip 23 deforms multiple times during the opening and closing process of the window sash 2 and is easily damaged due to fatigue stress. The detachable connection facilitates the replacement of the partition rubber strip 23, thus ensuring the heat insulation, airtightness and waterproof effects of the heat insulation structure.

[0055] In one embodiment, the partition rubber strip 23 is provided with at least two deformation cavities, and the second heat insulation strip 27 is a honeycomb heat insulation strip. In this way, by providing deformation cavities and a honeycomb heat insulation strip, the heat conduction efficiency is reduced by utilizing the heat attenuation in the cavities, thereby improving the heat insulation effect.

[0056] In one embodiment, the widths of the first heat insulation strip 131, the drainage rubber strip group 32 and the second heat insulation strip 27 are the same and are arranged on the same vertical plane. In this way, by arranging the first heat insulation strip 131, the drainage rubber strip group 32 and the second heat insulation strip 27 vertically, a heat insulation vertical plane is formed to avoid heat transfer caused by the contact of the aluminum profiles, thereby improving the heat insulation effect.

[0057] As Figure 2 and Figure 3 、 Figure 4As shown, in one embodiment, there is an installation gap between the window frame 1 and the window sash 2. The partition rubber strip 23 divides the installation gap into a first space 201 and a second space 202 by pressing against the drainage rubber strip group 32. There is a drainage cavity 120 between the window frame 1 and the adapter component 3, and the drainage cavity 120 communicates with the drainage holes. Specifically, the adapter component 3 includes a first adapter 31, a drainage rubber strip group 32, and a second adapter 33 arranged in sequence from the interior of the house to the outside. The second adapter 33 is provided with a second channel communicating the second space 202 and the drainage cavity 120. In this way, by dividing the installation gap into the first space 201 and the second space 202, it is convenient to collect the rainwater that leaks through the partition rubber strip 23, i.e., inside the heat-insulating vertical surface, into the first space 201, drain the rainwater from the drainage holes of the drainage rubber strip group 32 into the drainage cavity 120, collect the rainwater isolated outside the partition rubber strip 23, i.e., outside the heat-insulating vertical surface, into the second space 202, and then drain it into the drainage cavity 120 through the second channel, thereby discharging the rainwater that leaks into the window frame 1 and the window sash 2.

[0058] In one embodiment, the heat-insulating structure further includes a filling unit 4, and the filling unit 4 is arranged in the second installation groove 112 between the adapter component 3 and the window frame 1. Specifically, the window frame 1 and the adapter component 3 are provided with a first installation groove 111, a second installation groove 112, and a third installation groove 113 from top to bottom. The drainage rubber strip group 32 is snap-fitted on the first installation groove 111, the filling unit 4 is snap-fitted in the second installation groove 112, and the first heat-insulating strip 131 is snap-fitted on the third installation groove 113. In this way, by arranging the filling unit 4 below the drainage rubber strip group 32, it can prevent the rainwater that seeps into the drainage cavity 120 from leaking to the sealing rubber strip between the window frame 1 and the adapter component 3 and entering the room, playing a role in attenuating the rainwater and the pressure difference. At the same time, the filling unit 4 is used to support the drainage rubber strip group 32, thereby avoiding the deformation of the anti-backflow cavity 320 due to the long-term accumulation of rainwater, and further ensuring the structural stability.

[0059] In a specific implementation manner, the first installation groove 111 is arranged on the first adapter 31, the second installation groove 112 is formed by the snap connection of the first adapter 31 and the window frame 1, and the third installation groove 113 is arranged on the inner frame 11.

[0060] As Figure 7 shown, in one embodiment, the top of the blade frame strip 321 is an inclined structure. Specifically, the top surface of the blade frame strip 321 inclines downward towards the first space 201, and the drainage holes are arranged on the side close to the first adapter 31, i.e., the lowest end of the inclined structure. In this way, by setting the inclined structure, the rainwater isolated in the first space 201 flows along the top of the blade frame strip 321 into the drainage holes, and is drained through the anti-backflow cavity 320 and the drainage cavity 120 in sequence, avoiding the accumulation of rainwater on the top of the blade frame strip 321 when the doors and windows are closed.

[0061] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0062] The above embodiments only express several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be understood as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
