Description

Technical Field

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

[0002] In the field of building curtain wall technology, external circulation ventilation curtain walls are widely used because they combine the functions of lighting, heat insulation, and ventilation. Traditional external circulation ventilation curtain walls typically form a ventilation cavity by setting up two layers of curtain walls, using the temperature difference between indoors and outdoors to drive airflow and achieve a natural ventilation effect.

[0003] However, the filter structure of traditional ventilation curtain walls is mostly fixed or embedded, making it difficult to disassemble the filter components. This leads to untimely dust cleaning, affecting ventilation efficiency and air quality. In addition, the filter components of traditional curtain walls are not rationally arranged during bidirectional airflow (such as indoor and outdoor air exchange), making it unable to efficiently cope with the air purification needs of different airflow directions. Utility Model Content

[0004] The purpose of this invention is to solve the above problems by providing an external circulation ventilation curtain wall that is simple in structure, easy to maintain, and can efficiently achieve bidirectional airflow filtration.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: an external circulation ventilated curtain wall, including a mounting frame, on which an outer curtain wall and an inner curtain wall are respectively mounted on two opposite sides of the mounting frame. A rotating window is movably mounted on the inner curtain wall, and an inner layer of glass is fitted inside the rotating window. An external circulation component is connected to the top and bottom of the mounting frame. The external circulation component includes a ventilation hood, and a ventilation opening is provided on the side of the ventilation hood facing the outer curtain wall. A filter box is movably mounted between the ventilation hood and the top of the mounting frame. A cavity is provided inside the side of the ventilation hood facing the inner curtain wall, and a lifting plate is provided inside the cavity. A rotating wheel is rotatably connected to the bottom of the lifting plate, and the lifting plate is raised upward as the filter box is pulled outward.

[0006] Furthermore, a plurality of springs are provided between the top of the lifting plate and the inner top surface of the cavity, and a connecting rod is connected to the bottom of the lifting plate. The bottom of the connecting rod is rotatably provided with the rotating wheel via a rotating shaft.

[0007] Furthermore, the top of both sides of the filter box is provided with track grooves for the rotating wheel to roll, and the track grooves are provided with ramps that lift the lifting plate upward as the filter box is pulled outward.

[0008] Furthermore, a filter screen is retractably installed at the bottom of the mounting frame, and the filter screen is located above the external circulation component connected to the bottom of the mounting frame.

[0009] Furthermore, the ventilation opening is provided with several downward-sloping air guide plates.

[0010] Furthermore, a rotating shaft is fixedly connected to the middle position on both sides of the rotating window, and both rotating shafts are rotatably mounted on the mounting frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The filter box and the ventilation hood are connected by a pull-out mechanism. With the ramp and rollers in the track groove, when the filter box is pulled out, the rollers roll along the ramp to push the lifting plate up, and the spring is compressed, making it easy to disassemble without additional tools. When installing, the lifting plate is manually raised, and after the filter box is inserted, the spring returns to ensure that the filter box fits tightly with the mounting frame, balancing sealing and ease of disassembly.

[0013] 2. Regardless of whether the airflow direction is "bottom in, top out" (outdoor air enters the room through the bottom filter and indoor stale air is discharged through the top filter) or "top in, bottom out" (flows in the opposite direction according to the temperature difference), both the top filter box and the bottom filter screen can effectively filter the bidirectional airflow, preventing unpurified air from flowing directly and achieving true closed-loop purification.

[0014] 3. The lifting plate is connected to the top surface of the cavity by a spring. After the filter box is installed in place, the spring force makes the lifting plate press against the top surface of the filter box, ensuring that there is no gap between the ventilation cover and the mounting frame, preventing air leakage or dust infiltration.

[0024] Combination Figures 1 to 4 The external circulation ventilation curtain wall shown includes a mounting frame 1. An outer curtain wall 2 and an inner curtain wall 3 are respectively mounted on two opposite sides of the mounting frame 1. A rotating window 4 is movably mounted on the inner curtain wall 3. An inner layer of glass is fitted inside the rotating window 4. An external circulation component 5 is connected to the top and bottom of the mounting frame 1. The external circulation component 5 includes a ventilation hood 6. A ventilation opening 61 is opened on the side of the ventilation hood 6 facing the outer curtain wall 2. A filter box 7 is movably installed between the ventilation hood 6 and the top of the mounting frame 1. A cavity 8 is opened inside the side of the ventilation hood 6 facing the inner curtain wall 3. A lifting plate 9 is provided in the cavity 8. A rotating wheel 10 is rotatably connected to the bottom of the lifting plate 9. The lifting plate 9 is raised upward as the filter box 7 is pulled outward.

[0025] like Figure 3-4As shown, several springs 11 are provided between the top of the lifting plate 9 and the inner top surface of the cavity 8. Connecting rods are connected to the bottom of both ends of the lifting plate 9, and rotating wheels 10 are rotatably mounted on the bottom of the connecting rods via rotating shafts. Track grooves 71 for the rotating wheels 10 to roll are opened on the top of both sides of the filter box 7. Inclines 72 are provided in the track grooves 71 to raise the lifting plate 9 upward as the filter box 7 is pulled outward. When it is necessary to clean the filter box 7, the filter box 7 is pulled outward. At this time, the rotating wheels 10 are in the track grooves 71. As the filter box 7 is pulled out, the roller 10 moves uphill along the ramp 72, thereby lifting the lifting plate 9 upward in the cavity 8, and compressing the spring 11. Finally, the roller 10 moves to the edge of the horizontal top surface of the filter box 7, and the filter box 7 is smoothly pulled out. After cleaning the filter box 7, the lifting plate 9 can be manually lifted up during installation, and then the filter box 7 can be inserted back into the slot. Then the lifting plate 9 can be lowered so that the bottom surface of the lifting plate 9 is in contact with the top surface of the filter box 7.

[0026] like Figure 3 As shown, a filter screen 12 is retractably installed at the bottom of the mounting frame 1, and the filter screen 12 is located above the external circulation component 5 connected to the bottom of the mounting frame 1; a rotating shaft is fixedly connected to the middle position on both sides of the rotating window 4, and both rotating shafts are rotatably installed on the mounting frame 1; several downwardly inclined air guide plates 62 are provided at the vent 61; as Figure 5 As shown, when the lower half of the rotating window 3 rotates around the axis towards the outer curtain wall 2, the airflow can circulate internally and externally. The external airflow enters the ventilation hood 6 through the ventilation opening 61 at the bottom of the mounting frame 1, and then passes upward through the filter screen 12 to filter the dust in the airflow. The airflow then enters the room through the opening at the bottom of the rotating window 4. Large particles in the airflow, after being filtered by the filter screen 12, fall downward into the filter box 7 due to gravity. The filter box 7 at the bottom of the mounting frame 1 can be replaced by a dust collection box without filter holes to collect dust and large particles. The indoor hot airflow enters the ventilation hood 6 through the opening above the rotating window 4, passes through the filter box 7, and then is discharged to the outside through the ventilation opening 61. Figure 6 As shown, when the indoor temperature is lower than the outdoor temperature, the airflow direction is opposite. Nevertheless, both the filter box 7 and the filter screen 12 can filter the airflow from the outside to the inside, and the pull-out installation of the filter box 7 and the filter screen 12 makes it easy to disassemble and clean them.

[0027] Working principle: External air enters through the vent 61 of the bottom ventilation hood 6, and after being oriented by the air guide plate 62, clean air enters the room through the bottom opening of the rotating window 4 after passing through the filter screen 12. At the same time, the indoor polluted air is discharged through the top opening of the rotating window 4. The indoor air enters the ventilation hood 6 through the top external circulation component 5, and is finally discharged to the outside through the vent 61, forming a closed loop. When the filter box 7 is pulled out, the wheel 10 rolls along the slope 72 of the track groove 71, pushing the lifting plate 9 upward and compressing the spring 11, so that the filter box 7 is disengaged from the mounting frame 1 and can be easily pulled out. When resetting, the lifting plate 9 is manually lifted, the filter box 7 is inserted and then released. The spring 11 rebounds and presses the lifting plate 9 tightly against the filter box to ensure a tight seal.
