Description

Technical Field

[0001] This invention relates to the field of curtain wall technology, specifically to an external circulation ventilation curtain wall. Background Technology

[0002] External circulation ventilated curtain walls, also known as double-layer ventilated curtain walls, play a significant role in improving the thermal insulation, heat insulation, and sound insulation functions of curtain walls. Unlike traditional single-layer curtain walls, external circulation ventilated curtain walls consist of two layers: an inner layer and an outer layer. A relatively enclosed space is formed between the inner and outer layers. Air enters this space through the lower air inlet and exits through the upper air outlet. This space is called a thermal aisle. The air in the thermal aisle is constantly circulating and exchanging heat with the outer surface of the inner layer curtain wall. Therefore, double-layer ventilated curtain walls are also known as thermal aisle curtain walls.

[0003] Currently, when using external circulation ventilated curtain walls, to prevent outdoor insects from entering the gap between the two curtain walls through the air inlets and outlets, filter structures are usually added to the air inlets and outlets. However, as the external circulation ventilated curtain walls are used for a longer period of time, the filters become clogged with external dust and impurities, thus affecting the ventilation effect. In addition, some dust and impurities adhere to the glass between the two curtain walls, affecting the light transmission effect of the curtain wall. Furthermore, the external circulation ventilated curtain wall itself does not have a self-cleaning function, making the maintenance and cleaning of the air inlets, outlets, and the gap between the two curtain walls on the external circulation ventilated curtain wall very complicated and difficult. It is necessary to disassemble the inner curtain wall for thorough cleaning, which greatly affects the ease of maintenance of the external circulation ventilated curtain wall.

[0004] Combining the above issues, we find that existing external circulation ventilation curtain walls are difficult to avoid simultaneously when in use. Even if they can be solved, they require external tools, thus failing to achieve the desired effect. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figures 1-6The present invention provides a technical solution: an external circulation ventilation curtain wall, including a curtain wall mechanism 1, the curtain wall mechanism 1 including an inner frame 11, an inner window 12 is movably hinged to the inner wall of the inner frame 11, an outer frame 13 is fixedly connected to the right side of the inner frame 11, an outer window 14 is fixedly connected to the inner wall of the outer frame 13, and a cleaning mechanism 2 is provided inside the outer frame 13.

[0037] The cleaning mechanism 2 includes a dust cleaning unit 21, which is located inside the outer frame 13 and is used to clean dust.

[0038] As a further definition of the cleaning mechanism 2 of the present invention, the dust cleaning unit 21 includes an air inlet frame 2101 and an air outlet frame 2102. The outer surfaces of both the air inlet frame 2101 and the air outlet frame 2102 are fixedly connected to the inner wall of the outer frame 13. The upper surface of the air inlet frame 2101 and the bottom surface of the air outlet frame 2102 are respectively fixedly connected to opposite sides of the outer frame 13. An air inlet hood 2103 and an air outlet hood 2104 are respectively fixedly connected to the inner wall of the air inlet frame 2101 and the inner wall of the air outlet frame 2102. Sliding grooves 2105 are provided on opposite sides of 02. Sliding brackets 2106 are slidably connected to the inner walls of the two sliding grooves 2105. Movable brackets 2107 are provided on the inner walls of the air inlet bracket 2101 and the air outlet bracket 2102. The side of the two sliding brackets 2106 that is far apart from each other is fixedly connected to the side of the two movable brackets 2107 that is close to each other. Screws 2108 are rotatably connected to the inside of the air inlet bracket 2101 and the inside of the air outlet bracket 2102. The outer surfaces of the two screws 2108 are respectively connected to the two sliding brackets 2106. The inner wall of the 6 is threaded. Small motors 2109 are fixedly connected to the inner side walls of the air inlet frame 2101 and the air outlet frame 2102. The output ends of the two small motors 2109 are fixedly connected to one end of each of the two screws 2108. Fixed frames 2110 are slidably connected inside the two movable frames 2107. Rotating shafts 2111 are rotatably connected to the inner walls of the two fixed frames 2110. Several cleaning brush bristles 2112 are fixedly connected to the outer surfaces of the two rotating shafts 2111. A dust cleaning unit 21 is provided. The rotating shaft 2111 and the cleaning brush 2112 can quickly clean the dust and impurities in the filter holes of the air inlet hood 2103 and air outlet hood 2104, preventing the air inlet hood 2103 and air outlet hood 2104 from becoming clogged during long-term use. This not only ensures the ventilation effect of the air inlet hood 2103 and air outlet hood 2104, but also improves the ease of cleaning the air inlet hood 2103 and air outlet hood 2104, giving the external circulation ventilation curtain wall a self-cleaning function and effectively increasing the ease of maintenance of the external circulation ventilation curtain wall.

[0039] An installation plate 2113 is fixedly connected to the outer surface of the inner frame 11. Several installation holes 2114 are provided on the left side of the installation plate 2113. Several connection holes 2115 are provided on the upper and bottom surfaces of the outer frame 13. The installation plate 2113 and the installation holes 2114 can fix the inner frame 11 to the reserved opening of the building curtain wall, ensuring the smooth installation of the inner frame 11. The connection holes 2115 can ensure the normal connection between the outer frame 13 and other components of the building curtain wall.

[0040] The upper surface of the air inlet frame 2101 is provided with several air inlets 2116, and the bottom surface of the air outlet frame 2102 is provided with several air outlets 2117. The air inlets 2116 can ensure that outside air can smoothly pass through the air inlet frame 2101 and enter between the inner window 12 and the outer window 14, and the air outlets 2117 can ensure that the air between the inner window 12 and the outer window 14 can be discharged to the outside through the air outlet frame 2102, thus ensuring that the ventilation curtain wall can smoothly circulate external air.

[0041] The inner walls of the air inlet frame 2101 and the air outlet frame 2102 are provided with auxiliary grooves 2118. Two movable frames 2107 are slidably connected to the inside of the two auxiliary grooves 2118 respectively. The bottom surface of the air inlet frame 2101 and the bottom surface of the outer frame 13 are provided with several drain outlets 2119. Several drain outlets 2119 are connected to one of the auxiliary grooves 2118. The movable frame 2107 slides inside the auxiliary groove 2118, which can increase the movement stability of the movable frame 2107. The drain outlets 2119 can ensure that the wastewater after cleaning is discharged smoothly to the outside, preventing sewage accumulation from affecting the cleaning effect of the external circulation ventilation curtain wall.

[0042] The bottom surfaces of the two small motors 2109 are fixedly connected to the stabilizing bases 2120. One side of each stabilizing base 2120 is fixedly connected to the inner sidewall of the air inlet frame 2101 and the air outlet frame 2102, respectively. The stabilizing bases 2120 can fix the position of the small motors 2109 and increase the stability of the small motors 2109, allowing the small motors 2109 to drive the screw 2108 to rotate normally.

[0043] The specific implementation method of this embodiment is as follows: First, the small motor 2109 is connected to an external power supply and controller. When the filter holes on the air inlet hood 2103 and air outlet hood 2104 become clogged and need to be cleaned, the power provided by the small motor 2109 is used to drive the screw 2108 to rotate in conjunction with the air inlet frame 2101 and air outlet frame 2102. When the screw 2108 rotates, it can drive the sliding frame 2106 to slide in the sliding groove 2105, thereby driving the moving frame 2107 to move under the limit of the auxiliary groove 2118. When the moving frame 2107 moves, it can drive the rotating shaft 2111 to move through the fixed frame 2110. At this time, the cleaning brush bristles 2112 are used to move the air inlet hood 2103 and air outlet hood 2104. The friction force of 4 will force the rotating shaft 2111 to rotate in the fixed frame 2110. As the rotating shaft 2111 rotates and the cleaning bristles 2112 move, the cleaning bristles 2112 can be inserted into the filter holes of the air inlet hood 2103 and the air outlet hood 2104 to clean the impurities in the filter holes of the air inlet hood 2103 and the air outlet hood 2104, preventing the air inlet hood 2103 and the air outlet hood 2104 from being blocked during long-term use. This not only ensures the ventilation effect of the air inlet hood 2103 and the air outlet hood 2104, but also improves the ease of cleaning the air inlet hood 2103 and the air outlet hood 2104, giving the external circulation ventilation curtain wall a self-cleaning function and effectively increasing the ease of maintenance of the external circulation ventilation curtain wall.

[0044] Example 2: Please refer to Figures 6-8 The present invention provides a technical solution: an external circulation ventilation curtain wall. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The cleaning mechanism 2 also includes a scraping unit 22, which is disposed on the left side of the outer window 14. The scraping unit 22 is used to scrape dust off the inner window 12 and the outer window 14.

[0045] As a further definition of the cleaning mechanism 2 of the present invention, the scraping unit 22 includes a fixing plate 2201. Both ends of the fixing plate 2201 are fixedly connected to the opposite sides of two sliding frames 2106, respectively. A set of compression springs 2202 is fixedly connected to both sides of the fixing plate 2201, with five springs in each set. A positioning plate 2203 is fixedly connected to the other end of each set of compression springs 2202. A rubber scraper 2204 is fixedly connected to the side of each positioning plate 2203 that is far apart from the other side. The outer surfaces of the two rubber scrapers 2204 are in contact with the opposite sides of the inner window 12 and the outer window 14, respectively. Each set of compression springs 2202 has a telescopic rod 2205 inside. The telescopic end of each telescopic rod 2205 is fixedly connected to one side of the positioning plate 2203, and the other end of each telescopic rod 2205 is fixedly connected to one side of the fixing plate 2201. A connecting spring 2206 is fixedly connected to the inner wall of each movable frame 2107. The other ends of the two connecting springs 2206 are respectively connected to two fixed... The left side of the frame 2110 is fixedly connected, and two sliding blocks 2207 are fixedly connected to the left side of each of the two fixed frames 2110. Each sliding block 2207 is slidably connected inside the movable frame 2107. One end of each of the two rotating shafts 2111 is fixedly connected to a gear 2208. The left side of the air inlet hood 2103 and the left side of the air outlet hood 2104 are fixedly connected to racks 2209. The left side of each rack 2209 meshes with the outer surface of the two gears 2208. The two movable frames 210... The right side of 7 is provided with anti-scratch grooves 2210. By setting scraping unit 22, not only can the dust and impurities adhering to the opposite sides of the inner window 12 and the outer window 14 be scraped off, increasing the convenience of cleaning between the inner window 12 and the outer window 14, but it can also improve the tightness of the fit between the cleaning brush bristles 2112 and the air inlet cover 2103 and the air outlet cover 2104, so that the cleaning brush bristles 2112 can better remove the impurities in the filter holes of the air inlet cover 2103 and the air outlet cover 2104, making the self-cleaning effect of the external circulation ventilation curtain wall more superior.

[0046] The specific implementation of this embodiment is as follows: When the sliding frame 2106 moves inside the sliding groove 2105, it can drive the fixed plate 2201 to move. When the fixed plate 2201 moves, it can drive the rubber scraper 2204 to move through the compression spring 2202 and the positioning plate 2203. Then, by using the movement of the rubber scraper 2204, the dust and impurities adhering to the opposite sides of the inner window 12 and the outer window 14 can be scraped off, increasing the convenience of cleaning between the inner window 12 and the outer window 14. In addition, the telescopic rod 2205 can prevent the compression spring 2202 from bending excessively and shifting without affecting the normal extension and contraction of the compression spring 2202, thereby ensuring the scraping effect of the rubber scraper 2204. At the same time, when the moving frame 2107 moves, the elastic force provided by the connecting spring 2206, together with the sliding block 2207 sliding inside the moving frame 2107, limits the fixed frame 2110, which can be used to rotate the shaft 211. 1. The cleaning brush bristles 2112 provide thrust, allowing them to better conform to the air inlet shroud 2103 and the air outlet shroud 2104. Furthermore, when the connecting spring 2206 pushes the fixed frame 2110 and the rotating shaft 2111 to move, the gear 2208 can mesh with the rack 2209. Thus, as the moving frame 2107 and the fixed frame 2110 move, the rotating shaft 2111 and the cleaning brush bristles 2112 can maintain rotation more effectively. This improves the cleaning effect on the air inlet hood 2103 and air outlet hood 2104, making the self-cleaning effect of the external circulation ventilation curtain wall more superior. In addition, the rack 2209 and gear 2208 can limit the degree of contact between the cleaning bristles 2112 and the air inlet hood 2103 and air outlet hood 2104, preventing the cleaning bristles 2112 from being overly attached to the air inlet hood 2103 and air outlet hood 2104 and getting stuck in the filter holes of the air inlet hood 2103 and air outlet hood 2104 and unable to detach.

[0047] Example 3: Please refer to Figures 9-11 The present invention provides a technical solution: an external circulation ventilation curtain wall.

Both the first water storage chamber 301 and the second water storage chamber 302 are located inside the inner frame 11. A first water pump 303 is fixedly connected to the inner wall of the second water storage chamber 302. The outlet end of the first water pump 303 passes through the inner frame 11 and is fixedly connected to a first connecting pipe 304. The other end of the first connecting pipe 304 passes through the outer window 14 and the air inlet frame 2101 in sequence and is fixedly connected to... A first nozzle 305 has several first nozzles 306 fixedly connected to its outer surface. Each first nozzle 306 is at a certain angle to the first nozzle 305. A second water pump 307 is fixedly connected to the inner wall of a first water storage chamber 301. The outlet of the second water pump 307 passes through the inner frame 11 and is fixedly connected to a second connecting pipe 308.

A plurality of second nozzles 310 are fixedly connected to the outer surface of the nozzle 309. Each of the second nozzles 310 is at a certain angle to the second nozzle 309. A first water supply pipe 311 and a second water supply pipe 313 are fixedly connected to the outer surface of the second connecting pipe 308. Both the first and second water supply pipes 311 and 313 are located below the air outlet frame 2102. A plurality of third nozzles 31 are fixedly connected to the outer surfaces of the first and second water supply pipes 311 and 313, respectively. 2 and several fourth nozzles 314, through the setting of the flushing mechanism 3, can spray cleaning liquid such as glass cleaner directly onto the air inlet hood 2103, air outlet hood 2104 and the opposite side of the inner window 12 and the outer window 14. The cleaning with glass cleaner can not only assist the cleaning brush 2112 in cleaning the dust on the air inlet hood 2103 and the air outlet hood 2104, but also assist the rubber scraper 2204 in scraping the dust on the opposite side of the inner window 12 and the outer window 14, further improving the self-cleaning effect of the external circulation ventilation curtain wall;

[0049] Water inlet pipes 315 are fixedly connected to the outer surfaces of the first water storage chamber 301 and the second water storage chamber 302. The other ends of the two water inlet pipes 315 extend to the left side of the inner frame 11. Dust plugs 316 are snapped onto the top of the two water inlet pipes 315. The water inlet pipes 315 allow users to easily add glass cleaner and other cleaning fluids to the first water storage chamber 301 and the second water storage chamber 302. The dust plugs 316 prevent external dust and impurities from entering the interior of the water inlet pipes 315.

[0050] The outer surface of the first water supply pipe 311 is fixedly connected to several first positioning blocks 317. The left side of each of the first positioning blocks 317 is fixedly connected to the right side of the inner frame 11. The outer surface of the second water supply pipe 313 is fixedly connected to several second positioning blocks 318. The right side of each of the second positioning blocks 318 is fixedly connected to the left side of the outer window 14. The first positioning blocks 317 and the second positioning blocks 318 can fix the position of the first water supply pipe 311 and the second water supply pipe 313, preventing excessive swaying of the first water supply pipe 311 and the second water supply pipe 313 due to excessive internal pressure during use, thereby increasing the stability of the first water supply pipe 311 and the second water supply pipe 313.

[0051] Using the suction provided by the first water pump 303 and the second water pump 307, the cleaning fluid, such as glass cleaner, stored in the first water storage chamber 301 and the second water storage chamber 302 through the water inlet pipe 315 is drawn out and sent into the first spray pipe 305 and the second spray pipe 309 through the first connecting pipe 304 and the second connecting pipe 308. Then, in conjunction with the tilt angle of the first spray head 306 and the second spray head 310, the fluid is sprayed from the first spray head 306 and the second spray head 310 onto the air inlet hood 2103 and the air outlet hood 2104. At this time, the cleaning brush bristles 2112 clean the air inlet hood 2103 and the air outlet hood 2104, which can remove dust and impurities from the filter holes of the air inlet hood 2103 and the air outlet hood 2104 more quickly and effectively. The cleaning effect of the air inlet hood 2103 and air outlet hood 2104 is further improved. In addition, by using the first water supply pipe 311 and the second water supply pipe 313, part of the glass cleaner in the second connecting pipe 308 can be sprayed out through the third nozzle 312 and the fourth nozzle 314, so that part of the glass cleaner can be sprayed from top to bottom onto the opposite sides of the inner window 12 and the outer window 14. In conjunction with the scraping of the rubber scraper 2204, the dust and impurities adhering to the opposite sides of the inner window 12 and the outer window 14 can be better scraped off, thereby further improving the self-cleaning effect of the external circulation ventilation curtain wall. Finally, the wastewater generated by cleaning is discharged to the outside through the drain outlet 2119 at the bottom of the air inlet frame 2101 and the outer frame 13.
