Description

Technical Field

[0001] This invention relates to the field of building technology, and more particularly to a waterproof curtain wall unit and a curtain wall having the waterproof curtain wall unit. Background Technology

[0002] Curtain walls are often used on the exterior walls of buildings. Nowadays, curtain walls are widely used on buildings because they are lightweight walls with decorative effects.

[0003] In northern my country, during winter, the significant temperature difference between indoors and outdoors can cause large temperature fluctuations between the interior and exterior of curtain walls. When indoor heating (such as underfloor heating or radiators) is used, the outdoor temperature drops below freezing. This uneven heating, where one side of the curtain wall is heated while the other is cooled, leads to deformation. Since the curtain wall glass is bonded to the wall, this deformation can cause the adhesive to tear, creating gaps and compromising the wall's waterproofing. Ultimately, this reduces the waterproofing performance of the curtain wall units. Summary of the Invention

[0004] The purpose of this invention is to provide a waterproof curtain wall unit and a curtain wall having the waterproof curtain wall unit, so as to solve the problem that the adhesive between the curtain wall and the building ages due to temperature difference changes, resulting in gaps at the joint and a reduction in the waterproof performance of the curtain wall unit.

[0021] The first blower is disposed inside the mounting housing, with one side connected to the first air inlet and the other side connected to the first air outlet.

[0022] The first blower blows external air from the outside toward the first air outlet, so that an air duct is formed in the ventilation space along the first direction.

[0023] In at least one embodiment of this application, the mounting housing has an air outlet on the side near the ground that communicates with the ventilation space;

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0055] Please refer to Figures 1-4 An embodiment of the present invention provides a waterproof curtain wall unit 100, which includes:

[0056] The frame 110 has an installation cavity 110a, and has an outer side 110b and an inner side 110c opposite to the outer side 110b. The outer side 110b is located outdoors, and the inner side 110c is located indoors.

[0057] The first glass 120 is disposed in the mounting cavity 110a, near the inner side 110c;

[0058] The second glass 130 is disposed in the mounting cavity 110a and is located near the outer side 110b. A sealing cavity is formed between the first glass 120 and the second glass 130 (not shown in the figure).

[0059] The heat-conducting component 140 has one end located on the inner side 110c and the other end located on the second glass 130;

[0060] The temperature of the inner side 110c is conducted to the second glass 130 through the heat-conducting element 140 to reduce the temperature difference between the first glass 120 and the second glass 130.

[0061] Example 1:

[0062] In this embodiment, since one end of the heat-conducting element 140 is located on the inner side 110c and the other side is located on the second glass 130, and the second glass 130 is located close to the outer side 110b, a sealed cavity is formed between the first glass 120 and the second glass 130. During use, part of the indoor temperature will enter the sealed cavity through the first glass 120, and the other part will be conducted to the second glass 130 through the heat-conducting element 140. This prevents excessive temperature difference changes on the second glass 130, thereby avoiding the problem of tearing of the adhesive 190 between the second glass 130 and the frame 110 after the second glass 130 deforms due to temperature difference, and improving the waterproof performance of the curtain wall unit.

[0063] It should be noted that the heat-conducting component 140 is made of a metal heat-conducting material. In this embodiment, it is made of aluminum, and the heat-conducting component 140 has a roughly U-shaped structure.

[0064] In at least one embodiment of this application, the frame 110 is formed with a conductive cavity 110d, and an installation groove 110e communicating with the conductive cavity 110d is provided on the inner side 110c.

[0065] One end of the heat-conducting component 140 is located in the mounting groove 110e, and the other end extends into the conduction cavity 110d;

[0066] One end of the second glass 130 is located in the mounting cavity 110a, and the other end extends through the mounting cavity 110a into the conduction cavity 110d, and is fixedly connected to the heat-conducting component 140.

[0067] In at least one embodiment of this application, the heat-conducting member 140 has a heat-absorbing part 141 at one end and a heat-conducting part 142 at the other end, and the heat-conducting part 142 has a heat-conducting groove 142a.

[0068] The second glass 130 has a first side 130a near the inner side 110c and a second side 130b near the outer side 110b. The inner wall of the conduction groove 142a is respectively attached to the first side 130a and the second side 130b.

[0069] In at least one embodiment of this application, one end of the first glass 120 is disposed in the mounting cavity 110a, and the other end extends through the mounting cavity 110a into the conduction cavity 110d. The first glass 120 and the second glass 130 are arranged in parallel.

[0070] Example 2:

[0071] Please refer to Figures 1-7 In this embodiment, when the indoor and outdoor temperatures differ, the heat-conducting component 140 has a heat-absorbing part 141 at one end, which is located in the mounting groove 110e. At this time, the inner side 110c is located indoors, and the indoor temperature is conducted to the conducting part 142 through the heat-absorbing part 141. Since the conducting part 142 has a conducting groove 142a, and the first side 130a and the second side 130b of the second glass 130 are respectively attached to the inner wall of the conducting groove 142a, the indoor temperature can be conducted to the second glass 130 through the heat-conducting component 140. Another part of the indoor temperature is conducted to the sealed cavity through the first glass 120 and reaches the second glass 130, so that the temperature on the second glass 130 will not be lower than the outdoor temperature, and the temperature on the second glass 130 is more uniform, without large temperature differences. This avoids the second glass 130 from deforming due to uneven heating, which would cause gaps between the second glass 130 and the adhesive, thereby improving the waterproof performance of the curtain wall unit.

[0072] It should be noted that the conductive cavity 110d is a hollow structure, the conductive part 142 of the heat-conducting component 140 is a U-shaped structure, the heat-absorbing part 141 of the heat-conducting component 140 is a sheet-like structure, the frame 110 is a rectangular frame structure, and the conductive groove 142a is a rectangular groove. The width of the conductive groove 142a is the same as the width of the second glass 130.

[0073] In at least one embodiment of this application, the waterproof curtain wall unit 100 further includes

[0074] Ventilation component 150 is provided on the outer side 110b. Ventilation component 150 has a first air inlet 150a and a first air outlet 151a connected to the first air inlet 150a. The air outlet 151a is parallel to the second glass 130 and is set along the first direction A. The first direction A is set along the length direction of the second glass 130.

[0075] In at least one embodiment of this application, the ventilation assembly 150 includes

[0076] Mounting housing 151 is disposed on the outer side 110b. First air inlets 150a are provided on both sides of mounting housing 151 that are parallel to the length of the second glass 130. First air outlet 151a is provided on the side of mounting housing 151 that is perpendicular to the length of the second glass 130 and is located away from the ground. Mounting housing 151 is arranged around the second glass 130. A ventilation space 151b is formed in the middle of mounting housing 151. The second glass 130 is located in the ventilation space 151b.

[0077] The first blower 160 is disposed inside the mounting housing 151, with one side connected to the first air inlet 150a and the other side connected to the first air outlet 151a.

[0078] The first blower 160 blows external air from the outside to the first air outlet 151a, so that an air duct is formed in the ventilation space 151b along the first direction A.

[0079] In at least one embodiment of this application, the mounting housing 151 has an air outlet 151c communicating with the ventilation space 151b on the side near the ground.

[0080] The air blown from the first air outlet 151a blows along the first direction A toward the air outlet 151c and is blown out from the air outlet 151c.

[0081] In at least one embodiment of this application, the mounting shell 151 is provided with a second air inlet 151d and a second air outlet 151e. The second air outlet 151e is located inside the air outlet hole 151c. The angle between the air outlet direction of the air outlet hole 151c and the first direction A is α, and there is a relationship 60°≥α≥30°.

[0082] Waterproof curtain wall unit 100 also includes

[0083] The second blower 170 is disposed inside the mounting housing 151. One side of the second blower 170 is connected to the second air inlet 151d, and the other side is connected to the second air outlet 151e.

[0084] The air blown out by the second blower 170 is blown through the second air outlet 151e hole to the air outlet 151c, so that a negative pressure is formed in the air outlet 151c, and the air in the ventilation space 151b is drawn into the air outlet 151c.

[0085] In at least one embodiment of this application, each air outlet 151c is provided with two second air outlets 151e, and the two second air outlets 151e are provided on two opposite inner walls of the air outlet 151c.

[0086] Example 3:

[0087] Please refer to Figures 1-7In this embodiment, during rain, the first blower 160 operates. Since one side of the first blower 160 is connected to the first air inlet 150a and the other side is connected to the first air outlet 151a, during operation, the first blower 160 draws outside air into the first air inlet 150a and then blows it into the first air outlet 151a. The air blown out through the first air outlet 151a is directed along the first direction A towards the air outlet 151c and then blown out from the air outlet 151c. If rainwater enters at this time... When the air is inside the ventilation space 151b, the airflow blown out of the first air outlet 151a causes the surrounding airflow to move, so that most of the rainwater enters the air outlet 151c along the airflow blown out of the first air outlet 151a and is blown out to the outside from the air outlet 151c. This prevents rainwater from adhering to the second glass 130 or to the adhesive 190 connecting the second glass 130 and the frame 110, thereby avoiding the aging of the adhesive 190 due to rainwater and improving the sealing performance and service life of the adhesive 190.

[0088] Simultaneously, the second blower 170 operates, drawing in external air through the second air inlet 151d and then blowing it through the second air outlet 151e towards the air outlet 151c. Since the angle between the air outlet direction of the air outlet 151c and the first direction A is α, there exists a relationship 60°≥α≥30°, which causes the airflow speed along the first direction A to accelerate the airflow in the air outlet 151c, thereby creating a negative pressure in the air outlet 151c and ensuring that the airflow from the first blower 160 always moves along the first direction A.

[0089] Secondly, since each air outlet 151c is provided with two second air outlets 151e, and the two second air outlets 151e are arranged opposite to each other on the two inner walls, the two inner walls are symmetrically arranged so that the air blown by the two second air outlets 151e into the air outlet 151c forms a combined force, creating a greater negative pressure between the two second air outlets 151e. This further enables the air blown by the first air blower 160 to flow along the first direction A, so that a wind wall is formed in the ventilation space 151b facing the second glass 130, preventing rainwater or snow from adhering to the second glass 130 or the adhesive 190 connecting the second glass 130 and the frame 110, thereby improving the waterproof performance of the waterproof curtain wall unit 100.

[0090] It should be noted that the first blower 160 is a fan, and the second blower 170 can be an air compressor pump to accelerate the airflow in the air outlet 151c, which is a square through hole.

[0091] Specifically, if the angle between the air outlet 151c and the first direction A is α, when α > 60°, the air blown out by the two second air outlets 151e will collide with each other, thus canceling out a portion, so that the combined air speed cannot achieve a better effect. When α < 30°, the air blown out by the two second air outlets 151e forms an air duct inside the air outlet 151c, but the intersection of the air ducts is located at the end far away from the second glass 130, so that the air blown out by the first air outlet 151a cannot be better drawn into the air outlet 151c.

[0092] It should be further explained that in rainy or snowy weather, the rain and snow will adhere to the second glass 130 or the sealant. If the sealant is exposed to a relatively high temperature, it will accelerate the aging of the sealant, resulting in poor sealing performance.

[0093] The present invention proposes a curtain wall 180 having the waterproof curtain wall unit, which is applied to the waterproof curtain wall unit 100 mentioned above. The curtain wall 180 having the waterproof curtain wall unit is composed of multiple waterproof curtain wall units 100 spliced ​​together.

[0094] Please refer to Figures 1-8 In this embodiment, since one end of the heat-conducting element 140 is located on the inner side 110c and the other side is located on the second glass 130, and the second glass 130 is located close to the outer side 110b, a sealed cavity is formed between the first glass 120 and the second glass 130. During use, part of the indoor temperature will enter the sealed cavity through the first glass 120, and the other part will be conducted to the second glass 130 through the heat-conducting element 140. This prevents excessive temperature difference changes on the second glass 130, thereby avoiding the problem of tearing of the adhesive 190 between the second glass 130 and the frame 110 after the second glass 130 deforms due to temperature difference. This improves the waterproof performance of the curtain wall unit, thus enhancing the waterproof performance of the curtain wall 180 with this waterproof curtain wall unit.

[0095] Accordingly, the present invention provides a waterproof curtain wall unit 100, the waterproof curtain wall unit 100 comprising:

[0096] The frame 110 has an installation cavity 110a, and has an outer side 110b and an inner side 110c opposite to the outer side 110b. The outer side 110b is located outdoors, and the inner side 110c is located indoors.

[0097] The first glass 120 is disposed in the mounting cavity 110a, near the inner side 110c;

[0098] The second glass 130 is disposed in the mounting cavity 110a and near the outer side 110b, and a sealing cavity is formed between the first glass 120 and the second glass 130.

[0099] The heat-conducting component 140 has one end located on the inner side 110c and the other end located on the second glass 130;

[0100] The temperature of the inner side 110c is conducted to the second glass 130 through the heat-conducting element 140 to reduce the temperature difference between the first glass 120 and the second glass 130.

[0101] In this embodiment, since one end of the heat-conducting element 140 is located on the inner side 110c and the other side is located on the second glass 130, and the second glass 130 is located close to the outer side 110b, a sealed cavity is formed between the first glass 120 and the second glass 130. During use, part of the indoor temperature will enter the sealed cavity through the first glass 120, and the other part will be conducted to the second glass 130 through the heat-conducting element 140. This prevents excessive temperature difference changes on the second glass 130, thereby avoiding the problem of tearing of the adhesive 190 between the second glass 130 and the frame 110 after the second glass 130 deforms due to temperature difference, and improving the waterproof performance of the curtain wall unit.

[0102] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention.
