Description

Technical Field

[0001] The invention relates to the technical field of curtain walls, in particular to an external circulation ventilation curtain wall. Background Art

[0002] The external circulation ventilation curtain wall is also called the double-layer ventilation curtain wall. It plays a great role in improving the thermal insulation, heat insulation and sound insulation functions of the curtain wall. The external circulation ventilation curtain wall is different from the traditional single-layer curtain wall. It consists of an inner and outer curtain wall. A relatively closed space is formed between the inner and outer curtain walls. The air enters this space through the lower air inlet and leaves this space from the upper exhaust port. This space is called a hot channel. The air in the hot channel is always in a flowing circulation state and continuously exchanges heat with the outer surface of the inner curtain wall. Therefore, the double-layer curtain wall is also called a hot channel curtain wall.

[0003] At present, when the external circulation ventilation curtain wall is in use, in order to prevent outdoor mosquitoes from entering the gap between the two layers of curtain walls through the air inlet and outlet, a filter structure is usually added to the air inlet and outlet of the external circulation ventilation curtain wall. However, as the use time of the external circulation ventilation curtain wall increases, the filter will be blocked by external dust and impurities, thereby affecting the ventilation effect. In addition, some dust and impurities will adhere to the glass between the two layers of curtain walls, affecting the light transmission effect of the curtain wall. The external circulation ventilation curtain wall itself does not have a self-cleaning function, resulting in the maintenance and cleaning of the air inlet, air outlet and between the two layers of curtain walls on the external circulation ventilation curtain wall being very complicated and difficult. The inner curtain wall needs to be disassembled for sufficient cleaning, which greatly affects the convenience of maintenance of the external circulation ventilation curtain wall.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing external circulation ventilation curtain wall, and even if it can be solved, it needs to be solved through external tools, so it is impossible to achieve the desired effect.

By setting the 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, thereby increasing the cleaning convenience between the inner window 12 and the outer window 14, but also the tightness of the cleaning bristles 2112 and the air inlet cover 2103 and the air outlet cover 2104 can be improved, so that the cleaning bristles 2112 can better remove impurities in the filter holes of the air inlet cover 2103 and the air outlet cover 2104, thereby making the self-cleaning effect of the external circulation ventilation curtain wall more superior.

[0027] 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, the compression spring 2202 and the positioning plate 2203 can be used to drive the rubber scraper 2204 to move, and then the movement of the rubber scraper 2204 can be used to scrape off the dust and impurities adhering to the opposite sides of the inner window 12 and the outer window 14, thereby increasing the cleaning convenience between the inner window 12 and the outer window 14. In addition, the telescopic rod 2205 can prevent the compression spring 2202 from excessive bending and deviation 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 cooperates with the sliding block 2207 to slide inside the moving frame 2107 to limit the fixed frame 2110, which can be used for the rotation axis 211 1 and the cleaning bristles 2112 provide thrust, so that the cleaning bristles 2112 can better fit with the air inlet cover 2103 and the air outlet cover 2104, and when the connecting spring 2206 pushes the fixed frame 2110 and the rotating shaft 2111 to move, the gear 2208 can be engaged with the rack 2209, and then with the movement of the moving frame 2107 and the fixed frame 2110, the rotating shaft 2111 and the cleaning bristles 2112 can better keep rotating, further The cleaning effect of the air inlet hood 2103 and the air outlet hood 2104 is improved, making the self-cleaning effect of the external circulation ventilation curtain wall more excellent, and the rack 2209 cooperates with the gear 2208 to limit the degree of fit between the cleaning bristles 2112 and the air inlet hood 2103 and the air outlet hood 2104, preventing the cleaning bristles 2112 from being overly fit to the air inlet hood 2103 and the air outlet hood 2104 and getting stuck in the filter holes of the air inlet hood 2103 and the air outlet hood 2104 and unable to detach.
