Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, specifically a curtain wall ventilation system. Background Technology

[0002] Curtain wall ventilation is an important design element in modern architecture. It is crucial for maintaining fresh indoor air, suitable temperature and humidity. Effective ventilation design can also reduce the energy consumption of air conditioning systems and improve the comfort of the indoor environment.

[0003] A ventilation curtain wall system is disclosed in Chinese utility model patent with publication number CN212689337U. The system has two openings on the upper and lower sides of the curtain wall and one opening in the middle of the inner layer. By opening the movable window on the middle opening, outside air enters the room through the lower opening and the movable window, while indoor air is exhausted through the movable window and the upper opening, achieving airflow from bottom to top. However, during ventilation, the size of the air inlet and outlet is relatively equal, making it difficult to adjust after installation. This is not conducive to flexibly controlling the indoor air volume to meet the ventilation requirements of different occasions and needs. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a curtain wall ventilation system.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A curtain wall ventilation system includes a curtain wall frame body with an inner cavity connecting the inside and outside. Several layered panels are installed within the inner cavity, dividing it into several ventilation channels. Each ventilation channel has an outdoor guide mechanism connected to its outer side, which restricts unidirectional airflow. A second control component is installed on the guide mechanism to adjust and control the airflow direction, thereby enabling the ventilation channels to form multiple air intake channels and multiple air exhaust channels, thus regulating the size of the total air intake and exhaust channels.

[0007] Furthermore, several layered plates are distributed at equal intervals from top to bottom, so that the several ventilation channels of the same size are arranged at equal intervals from top to bottom.

[0008] Furthermore, the guiding mechanism includes several housings, the bottom of which is rotatably connected to the top of the corresponding layered plate. The housings are symmetrically provided with connected air inlets and outlets so that the housings connect to the outside and the ventilation channel.

[0009] Inside the casing, between the air inlet and the air outlet, there is a control valve that restricts the one-way flow of air.

[0010] Furthermore, rain covers are installed at both the air inlet and outlet of the casing.

[0011] Furthermore, the inner wall of the layered plate has a cavity, and the second control component is installed inside the cavity;

[0012] The second control component includes a transmission mechanism, one side of which is connected to the housing, and the other side of which is connected to a control panel. The outer side of the control panel extends through the layered panel to the interior side of the curtain wall frame body, so as to drive the housing to rotate via the control panel.

[0013] Furthermore, the transmission mechanism includes a positioning shaft rotatably connected to the inner wall of the cavity, and the number of positioning shafts is at least five. Four of the positioning shafts are rectangularly distributed, and the outer sides of two of the positioning shafts are fixedly connected to the control panel respectively. The fifth positioning shaft is located below the outer shell and is fixedly connected to the bottom of the outer shell. The outer sides of the five positioning shafts are connected through a transmission structure.

[0014] Furthermore, a first control component is provided on the inner side of the main body of the curtain wall frame, through which several ventilation channels are opened or closed;

[0015] The first control component includes several control structures, which are distributed in several ventilation channels. The bottom of each control structure passes through a corresponding layered plate below. The upper control structure is connected to the lower control structure, and the bottom of the lowest control structure is connected to a drive component, so that the drive component drives the control structures to open or close the ventilation channels.

[0016] Furthermore, the control structure includes several second sealing plates that all penetrate the layered plate. The bottom of each of the second sealing plates is fixedly connected to the top of a horizontal plate. From top to bottom, the horizontal plate of the first control structure at the top is fixedly connected to the top of the second sealing plate of the second control structure at the bottom, and so on. The bottom horizontal plate of the last control structure is connected to the drive structure.

[0017] Several first sealing plates are fixedly connected to the upper surface of several layered plates. The first sealing plates are distributed at equal intervals along a straight line on the top of the layered plates, and the first sealing plates on the upper layered plates and the first sealing plates on the lower layered plates are staggered.

[0018] Among them, several first sealing plates and several second sealing plates are staggered on the same layer of the layered plate.

[0019] Furthermore, several ventilation ducts are equipped with adjusting blades on their indoor sides to regulate the airflow direction of the incoming indoor air.

[0020] Compared with existing technologies, this curtain wall ventilation system has the following advantages:

[0021] I. This utility model forms several ventilation channels on the curtain wall frame through layered panels, and installs guide mechanisms in the ventilation channels to restrict airflow within the channels, thereby forming air intake and exhaust channels. Then, through a second control component, the relative increase and decrease of the air intake and exhaust channels can be controlled by adjusting the direction of the guide mechanisms, achieving flexible control of air intake and exhaust volume. This solves the problem that the air intake and exhaust vents of existing curtain wall ventilation systems are difficult to adjust after installation, which is not conducive to flexible control of indoor air volume.

[0022] Second, this utility model uses a layered plate with vertical distribution to create several ventilation channels that are distributed sequentially from top to bottom. Then, a guide mechanism is used to form air inlet and outlet, so as to flexibly adjust and control the height of the air inlet and outlet positions, assisting indoor air conditioning or floor heating and reducing power consumption.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] like Figure 1-6 As shown, this utility model provides a technical solution: a curtain wall ventilation system, including a curtain wall frame body 1, an inner cavity connecting the inside and outside of the curtain wall frame body 1, a plurality of layered plates 7 are provided in the inner cavity, the layered plates 7 divide the inner cavity into a plurality of ventilation channels, and the outdoor side of each ventilation channel is connected to a guide mechanism 6 that can restrict the unidirectional flow of air, and a second control component 5 is provided on the guide mechanism 6, the second control component 5 is used to adjust and control the air guidance of the guide mechanism 6, so that the plurality of ventilation channels respectively form multiple air inlet channels and multiple air outlet channels, so as to play the role of regulating the size of the total air inlet channel and the total air outlet channel.

[0032] In use, the layered panel 7 forms several ventilation channels within the main body of the curtain wall frame 1. These ventilation channels are then divided into air intake channels and exhaust channels. When it is necessary to increase the air intake and decrease the exhaust volume, the guide mechanism 6 is rotated 180 degrees by the corresponding second control component 5, thereby flipping the air intake and exhaust sides of the guide mechanism 6 and converting the exhaust channel into an air intake channel. This increases the air intake channel and decreases the exhaust channel, thereby increasing the air intake volume and decreasing the exhaust volume.

[0033] Several layered plates 7 are distributed at equal intervals from top to bottom, so that several ventilation channels of the same size are arranged at equal intervals from top to bottom. In use, the ventilation channels are distributed from top to bottom, which facilitates the formation of air intake and exhaust channels at different heights under the control of the second control component 5, so as to achieve the effect of adjusting the position and height of the air intake and exhaust channels.

[0034] The guiding mechanism 6 includes several housings 601. The bottoms of the housings 601 are rotatably connected to the tops of corresponding layered plates 7. Symmetrically arranged on each housing 601 are air inlets and outlets, allowing the housing 601 to connect to the outside and a ventilation duct. A control valve 602 is connected inside each housing 601 between the air inlet and outlet, restricting one-way airflow. The control valve 602 is a Tesla check valve; and the air inlet and outlet of the Tesla check valve are adapted to the air inlet and outlet. Several control valves 602 are distributed within each housing 601, restricting the air inlet and outlet. The direction of airflow between the two; both the air inlet and outlet of the outer casing 601 are equipped with rain covers 603; during use, the rain covers 603 serve to shield against rainwater, preventing rainwater from entering the interior of the outer casing 601; during use, outside air enters the interior of the outer casing 601 through the air inlet, then passes through the control valve 602 and is discharged at the air outlet. When it is necessary to adjust the airflow, the outer casing 601 is rotated, which in turn drives the control valve 602 to rotate, rotating the air inlet 180 degrees and moving it to the inside of the ventilation channel, changing the airflow from the outdoor channel to the channel flowing to the outside, thus realizing the switching between air intake and exhaust.

[0035] The inner wall of the layered plate 7 has a cavity, and the second control component 5 is installed inside the cavity. The second control component 5 includes a transmission mechanism. One side of the transmission mechanism is connected to the outer shell 601, and the other side of the transmission mechanism is connected to a control panel 501. The outer side of the control panel 501 extends through the layered plate 7 to the interior side of the curtain wall frame body 1, so that the outer shell 601 is driven to rotate through the control panel 501. The transmission mechanism includes a positioning shaft 502 rotatably connected to the inner wall of the cavity, and the number of positioning shafts 502 is at least five. Four of the positioning shafts 502 are rectangularly distributed, and the outer sides of two of the positioning shafts 502 are fixedly connected to the control panel 501 respectively. The fifth positioning shaft 502 is located below the outer shell 601 and is fixedly connected to the bottom of the outer shell 601. The outer sides of the five positioning shafts 502 are connected through a transmission structure 503.

[0036] The transmission structure 503 can be driven by a belt or a chain. When using a belt or chain, corresponding pulleys or sprockets are installed on the positioning shaft 502 to facilitate normal power transmission. By rotating the control disk 501, the control disk 501 drives the corresponding positioning shaft 502 to rotate. The positioning shaft 502 drives the positioning shaft 502 located below the outer shell 601 to rotate through the transmission structure 503, thereby causing the positioning shaft 502 to drive the outer shell 601 to rotate. The positioning shaft 502 passes through the cavity and is fixedly connected to the outer shell 601. Multiple positioning shafts 502 are used to limit the transmission structure 503, so that the transmission structure 503 is distributed along the inner wall of the side of the cavity, and a storage groove is opened inside for the transmission structure 503 to pass through.

[0037] A first control component 3 is provided on the inner side of the curtain wall frame body 1. The first control component 3 opens or closes several ventilation channels. The first control component 3 includes several control structures 303, which are distributed in several ventilation channels. The bottom of each control structure 303 passes through the corresponding layered plate 7 below. The upper control structure 303 is connected to the lower control structure 303, and the bottom of the lowest control structure 303 is connected to a drive component so that the drive component drives the several control structures 303 to open or close the ventilation channels. In use, the drive component can be an electric telescopic rod 301, which drives the multiple control structures 303 to move up and down to open or close the ventilation channels.

[0038] The control structure 303 includes several second sealing plates that all penetrate the layered plates 7. The bottom of each of the second sealing plates is fixedly connected to the top of a horizontal plate. From top to bottom, the horizontal plate of the first control structure 303 at the top is fixedly connected to the top of the second sealing plate of the second control structure 303 at the bottom, and so on. The bottom horizontal plate of the last control structure 303 is connected to the drive structure. Several first sealing plates 302 are fixedly connected to the upper surface of the layered plates 7. The first sealing plates 302 are distributed at equal intervals along a straight line on the top of the layered plates 7, and the first sealing plates 302 on the upper layered plates 7 and the first sealing plates 302 on the lower layered plates 7 are staggered. Among them, the first sealing plates 302 and the second sealing plates on the same layered plate 7 are staggered.

[0039] In use, the electric telescopic rod 301 drives multiple sets of second sealing plates to move. When the ventilation channel is opened, the second sealing plate of the first layer moves down to the side of the first sealing plate 302 of the second layer, the sealing plate of the second layer moves to the side of the first sealing plate 302 of the third layer, and so on. Since the second sealing plate of each layer moves to the side of the first sealing plate 302 of the next layer, the gap between two adjacent first sealing plates 302 is opened, thereby allowing air to circulate. At the same time, soft rubber sealing gaskets are fixedly connected to the side of the first sealing plate 302 that contacts the second sealing plate to improve the sealing performance. In addition, the distance between the first sealing plate 302 and the outer shell 601 is adapted to facilitate the rotation of the outer shell 601.

[0040] Several ventilation ducts are equipped with adjusting blades 2 on their indoor sides to adjust the airflow direction of the incoming indoor air. When in use, the adjusting blades 2 can be adjusted by referring to the principle of the adjusting blades of the air outlet of an automobile air conditioner. They are detachably connected to the inner wall of the ventilation duct to adjust the airflow direction. A filter assembly 4 is detachably connected to the side of the adjusting blades 2 facing the first sealing plate 302. The filter assembly 4 can be an air dust filter to filter and purify air dust.
