Description

Technical Field

[0001] The present application relates to the technical field of building curtain walls, and in particular to a double-layer ventilated energy-saving curtain wall. Background Art

[0002] With the popularization of energy-saving and environmental protection concepts, the energy-saving performance of building curtain walls, as an important part of the building's external envelope structure, has received more and more attention. Traditional single-layer curtain walls have certain limitations in terms of thermal insulation, heat insulation, ventilation, etc., and cannot meet the needs of modern buildings for high-performance curtain walls. Double-layer curtain walls came into being. With the development of the construction industry, double-layer curtain walls have become widely known for their excellent thermal insulation, sound insulation and ventilation performance.

[0003] Double-skin curtain wall is also called heat channel curtain wall, breathing curtain wall, ventilation curtain wall, energy-saving curtain wall, etc. It consists of two layers of facade structure, forming an air buffer layer between indoor and outdoor. However, after long-term ventilation, the air buffer layer of the double-skin curtain wall is prone to accumulate dust and dirt. Due to its excellent heat insulation, sound insulation and ventilation, it is very difficult to clean the space in the air buffer layer under the condition of ensuring sealing, which makes the cost of cleaning and maintenance very high, thus hindering the popularity of double-skin curtain walls. Utility Model Content

[0004] In order to improve the convenience of cleaning the air buffer layer in a double-layer curtain wall, the present application provides a double-layer ventilation energy-saving curtain wall.

[0005] The double-layer ventilated energy-saving curtain wall provided in this application adopts the following technical solution:

[0006] A double-layer ventilated energy-saving curtain wall comprises an outer glass curtain wall and an inner glass curtain wall, wherein a ventilation box is installed on the top and bottom ends of the outer glass curtain wall and the inner glass curtain wall, and each of the ventilation boxes is provided with ventilation holes on the side walls facing indoors and outdoors, and each of the ventilation boxes is slidably provided with a blocking member for blocking the ventilation holes, a hollow cavity is surrounded by the two ventilation boxes and the outer glass curtain wall and the inner glass curtain wall, the ventilation boxes are connected to the hollow cavity, and a cleaning component for cleaning the opposite side walls of the outer glass curtain wall and the inner glass curtain wall is also provided in the hollow cavity, the cleaning component comprises a scraping frame slidably arranged in the hollow cavity and a driving member for driving the scraping frame to slide, the scraping frame matches the hollow cavity and abuts against the inner side walls opposite to the outer glass curtain wall and the inner glass curtain wall.

[0007] By adopting the above technical solution, users can selectively drive the sliding blocking parts to block the indoor or outdoor vents according to different needs in summer and winter, so as to switch the internal and external circulation modes of the double-layer ventilation curtain wall, reduce the loss during heat transfer and ensure the ventilation effect. After long-term use, when the dust accumulated in the hollow cavity and adhered to the opposite side walls of the outer glass curtain wall and the inner glass curtain wall affects the light transmission effect and neatness of the double-layer curtain wall, the user can turn off the external circulation at this time, and can quickly drive the scraping frame to slide up and down through the driving part, and directly scrape the dust on the opposite side walls of the outer glass curtain wall and the inner glass curtain wall during the sliding process, and scrape the dust into the ventilation box at the bottom, so that the double-layer curtain wall can be restored to its original state. The fast, efficient and low-cost cleaning of the hollow structure of the double-layer curtain wall is achieved, the cleaning efficiency is improved, the cleaning cost is reduced, and the performance and appearance of the double-layer curtain wall are guaranteed.

[0008] Optionally, fixed blocks are provided on the inner side walls relative to the outer glass curtain wall and the inner glass curtain wall, near the bottom ventilation box, and the driving member includes a screw rod vertically rotatable between one of the fixed blocks and the bottom wall of the top ventilation box, and a rotating motor driving the screw rod to rotate, the screw rod is threadedly rotated to penetrate a scraping frame, a guide rod is vertically provided between the other fixed block and the bottom wall of the top ventilation box, and the guide rod slides through the scraping frame.

[0009] By adopting the above technical solution, the user starts the driving switch of the rotating motor to drive the output shaft of the rotating motor to rotate, thereby driving the screw rod coaxially connected thereto to rotate. At this time, under the limit guidance of the guide rod, the rotation of the screw rod causes the scraping frame to slide up and down in contact with the opposite side walls of the outer glass curtain wall and the inner glass curtain wall, and the dust accumulated and adhered on the opposite side walls of the outer glass curtain wall and the inner glass curtain wall is scraped off, so as to achieve fast, efficient and low-cost cleaning.

[0010] Optionally, a felt is provided on the outer ring side wall of the scraping frame, and the felt abuts against the inner side walls of the outer glass curtain wall and the inner glass curtain wall that are opposite to each other.

[0011] By adopting the above technical solution, when the double-layer curtain wall is in external circulation, the outdoor air is prone to carry floating objects such as cotton wool, which are difficult to scrape off by ordinary scraping. However, the felt can adhere to the cotton wool during the sliding process, thereby further improving the cleaning effect.

[0012] Optionally, a guide surface facing the inner bottom of the hollow cavity is provided on the inner ring side wall of the scraping frame.

[0013] By adopting the above technical solution, when the scraping frame scrapes the inner side walls of the outer glass curtain wall and the inner glass curtain wall during the upward sliding process, when excessive dust falls onto the scraping frame, it falls to the bottom ventilation box along with the guide surface. The user does not need to clean the scraping frame later, thereby improving the degree of automation of cleaning the hollow cavity.

[0014] Optionally, a plug interface is provided on the side wall of the inner glass curtain wall facing the interior and connected to the hollow cavity, the plug interface is arranged below the fixed block, and a cover is hinged at the plug interface, a sealing gasket is arranged in the plug interface and is in contact with the cover, and a collection box is provided at the bottom of the fixed block and is plugged into the plug interface, and the collection box matches the internal size of the hollow cavity.

[0015] By adopting the above technical solution, when the dust in the hollow cavity in the double-layer curtain wall needs to be cleaned, the external circulation of the double-layer curtain wall is closed, the cover is opened, and the collection box is inserted into the hollow cavity from the plug interface, and the scraping frame is driven to slide up and down to collect the dust scraped off by the scraping frame, which is convenient for centralized processing of fallen dust and reduces the difficulty of cleaning fallen dust from the double-layer curtain wall.

[0016] Optionally, an electric louver is provided in the hollow cavity, the electric louver is located in the middle of the scraping frame, and the top of the electric louver is movably connected to the bottom wall of the ventilation box.

[0017] By adopting the above technical solution, the setting of electric louvers has the effect of adjusting the indoor light and improving the comfort of using the double-layer curtain wall.

[0018] Optionally, the blocking member includes a ventilation grille arranged near the air outlet and a blocking frame plugged into and matched with the ventilation grille, and sliding grooves are provided on opposite sides of the inner wall of the ventilation box along the sliding direction of the blocking frame, the sliding groove is parallel to the length direction of the ventilation box, and a slider is slidably arranged in the sliding groove, the slider is arranged on the blocking frame, and a screw rod is rotatably arranged in the sliding groove along its own length direction, the screw rod is threadedly rotated to penetrate the slider, and a driving motor for driving the screw rod to rotate is arranged on the ventilation box.

[0019] By adopting the above technical solution, when it is summer, the drive motor is started to drive the screw rod to rotate. At this time, the blocking frame follows the rotation of the screw rod and moves toward the ventilation grille close to the indoor vent until the blocking frame is plugged into the ventilation grille to completely block the vent close to the indoor room. At this time, the double-layer curtain wall is in an external circulation state, and the natural wind flowing outdoors passes through the hollow cavity to take away the heat directly exposed to the sun on the double-layer curtain wall, making the indoor temperature cooler and more comfortable. In winter, the movement is reversed, and the double-layer curtain wall is in an internal circulation state. At this time, the heat directly exposed to the sun on the double-layer curtain wall is passed through the hollow cavity by the natural air flow flowing indoors, and the heat directly exposed to the sun on the double-layer curtain wall is brought into the room, thereby increasing the indoor temperature and making the indoor temperature warmer and more comfortable.

[0020] Optionally, filters are installed at the air outlets of the ventilation box facing indoors and outdoors.

[0021] By adopting the above technical solution, the setting of the filter not only reduces the dust in the air from entering the hollow cavity and increases the time interval for users to clean the dirt in the hollow cavity, but also reduces the possibility of outdoor dust entering the room during the use of the double-layer curtain wall, causing the air to be unfresh. In addition, the detachable setting of the filter makes it easy for users to directly disassemble and clean it.

[0022] Optionally, a plurality of side V-shaped ventilation holes are provided on the side walls of the hollow cavities connected to the two ventilation boxes.

[0023] By adopting the above technical solution, the setting of several side V-shaped ventilation holes can disturb the wind speed entering the hollow cavity, and pass through the hollow cavity at a smooth and gentle speed, thereby reducing the possibility of the double-layer curtain wall shaking due to strong wind and improving the stability of the double-layer curtain wall during use.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. According to different needs in summer and winter, users can selectively drive the sliding blocking parts to block indoor or outdoor vents to switch between the internal and external circulation modes of the double-layer ventilation curtain wall, which reduces heat loss during transfer and ensures ventilation effect. After long-term use, when the dust accumulated in the hollow cavity and adhered to the opposite side walls of the outer glass curtain wall and the inner glass curtain wall affects the light transmission effect and cleanliness of the double-layer curtain wall, the user can turn off the external circulation and use the driving part to quickly drive the scraping frame to slide up and down. During the sliding process, the dust on the opposite side walls of the outer glass curtain wall and the inner glass curtain wall can be directly scraped and dropped into the ventilation box at the bottom, so that the double-layer curtain wall can be restored to its original state. It realizes fast, efficient and low-cost cleaning of the hollow structure of the double-layer curtain wall, improves cleaning efficiency, reduces cleaning costs, and at the same time ensures the performance and appearance of the double-layer curtain wall;

[0026] 2. The user starts the driving switch of the rotary motor to drive the output shaft of the rotary motor to rotate, thereby driving the screw connected coaxially therewith to rotate. At this time, under the limit guidance of the guide rod, the rotation of the screw causes the scraping frame to slide up and down in contact with the opposite side walls of the outer glass curtain wall and the inner glass curtain wall, and the dust accumulated and adhered to the opposite side walls of the outer glass curtain wall and the inner glass curtain wall is scraped off, so as to achieve fast, efficient and low-cost cleaning;

[0027] 3. When the double-layer curtain wall is in external circulation, the outdoor air is prone to contain floating objects such as cotton wool, which are difficult to scrape off by ordinary scraping. However, the felt can adhere to the cotton wool during the sliding process, thereby further improving the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS
