Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, and in particular to an indoor natural fresh air circulation device for buildings. Background Technology

[0002] During the period of living in a newly renovated house and using public restrooms, the most prominent environmental problem encountered is air quality. Poor air quality is a major factor in the unpleasant experience, especially in special environments such as relatively enclosed, windowless spaces with specific temperature and humidity requirements (such as underground projects and museums). To prevent indoor air pollution, current indoor air exhaust systems use electric fans. However, using electric fans for exhaust can cause noise and power frequency radiation problems. Moreover, electric fans are often fixed in one location, and indoor airflow is often affected by room temperature, ultimately resulting in poor exhaust performance, which urgently needs improvement.

The intake device is installed on both indoor side walls, and the exhaust device is installed at the ceiling. Both the intake fan and the exhaust fan are located outdoors and connected to the intake device and exhaust device respectively via connecting pipes. The intake device includes an extended air duct, a movable air outlet pipe, and a control mechanism. One end of the extended air duct is provided with a baffle, and the baffle has... A main air inlet is connected to an outdoor air intake fan via a connecting pipe. An evenly spaced air outlet plate is provided in the extended air duct, and the evenly spaced air outlet plate has several air holes. A movable air outlet pipe is rotatably connected to the other end of the extended air duct. A control mechanism is located on both sides of the extended air duct and connected to the movable air outlet pipe. The exhaust device includes a suspended air duct, an air outlet, and a louvered plate. The suspended air duct is located at the top of the room, with one end connected to the air outlet and the other end connected to the exhaust fan via a connecting pipe. The louvered plate is located on the air outlet.

[0004] By adopting the above technical solution, and by setting up a fresh air exchange equipment including an intake fan, an intake device, an exhaust fan, an exhaust device, and several connecting pipes, and placing both the intake fan and the exhaust fan outdoors, the noise problem of air exchange and circulation is effectively solved. Furthermore, based on the directional characteristics of airflow, the intake device is placed on both sides of the lower part of the room, and the exhaust device is placed at the top center of the room, so that the fresh air circulation airflow enters from the bottom and exits from the top, enters from the side and exits from the middle. By controlling the movable air outlet of the intake device through several inlets, the air outlet angle can be controlled according to changes in room temperature, ensuring stable circulation of indoor airflow and guaranteeing the circulation and exhaust effect.

[0005] Further features of this invention: The control mechanism includes a temperature sensor, a control unit, a pair of drive motors, and a pair of connecting shafts. The pair of drive motors are located on both sides of the extended air duct, and the pair of connecting shafts are located on both sides of the movable air outlet and connected to the drive motors. The temperature sensor is located on the extended air duct and connected to the drive motors through the control unit.

The pair of drive motors are located on both sides of the extended air duct, and the pair of connecting shafts are located on both sides of the movable air outlet duct and connected to the drive motors. The temperature sensor is located on the extended air duct and connected to the drive motors through the control unit. The room temperature measured by the temperature sensor is fed back to the control unit, and then the drive motors control the rotation of the movable air outlet duct, so that the movable air outlet duct can deliver air into the room at different angles under different room temperatures, thereby improving the coverage efficiency of indoor ventilation.

[0007] A further feature of this invention is that a plurality of airflow guiding baffles are provided in the extended air duct near the movable air outlet pipe, and the plurality of airflow guiding baffles are evenly arranged on the upper and lower inner walls of the extended air duct.

[0008] By adopting the above technical solution, since several airflow guiding baffles are provided in the extended air duct near the movable air outlet pipe, and the several airflow guiding baffles are evenly arranged on the upper and lower inner walls of the extended air duct, the airflow guiding baffles can guide the airflow and also increase the flow length of the airflow, so that the dust carried by the airflow can adhere to the surface of the baffles after passing through the several airflow guiding baffles, thus playing a certain filtering role.

[0009] A further feature of this invention is that the extended air duct has cleaning ports on both sides of the uniform air outlet plate, and a detachable cover plate is provided on the cleaning ports. A portion of several airflow guiding baffles is located below the cover plate.

[0010] By adopting the above technical solution, since the extended air duct has cleaning ports on both sides of the uniform air outlet plate and a detachable cover plate is provided on the cleaning port, and a portion of several airflow guiding baffles are set below the cover plate, the extended air duct can be easily and quickly disassembled to clean the inside of the extended air duct, avoiding the problem of poor circulation effect caused by dust accumulation after long-term use.

Detailed Implementation

[0016] like Figure 1-4 The illustrated indoor natural fresh air circulation device for buildings includes an intake fan 1, an intake device 2, an exhaust fan 3, an exhaust device 4, and several connecting pipes 5. The intake device is installed on both indoor side walls, and the exhaust device is installed at the ceiling. The intake fan and exhaust fan are both installed outdoors and connected to the intake device and exhaust device respectively via connecting pipes. The intake device includes an extended air duct 6, a movable air outlet 7, and a control mechanism 8. One end of the extended air duct is provided with a baffle 9, and a main air inlet 10 is provided on the baffle. The main air inlet is connected to the outdoor air intake fan via a connecting pipe. A uniform air outlet plate 11 is provided in the extended air duct, and the uniform air outlet plate is provided with several air holes 12. The movable air outlet pipe is rotatably connected to the other end of the extended air duct. The control mechanism is set on both sides of the extended air duct and connected to the movable air outlet pipe. The exhaust device includes a suspended air duct 13, an air outlet 14, and a louvered plate 15. The suspended air duct is set on the top of the room and one end is connected to the air outlet, and the other end is connected to the exhaust fan via a connecting pipe. The louvered plate is set on the air outlet.

[0017] By installing a fresh air exchange system that includes an intake fan, an intake device, an exhaust fan, an exhaust device, and several connecting pipes, and placing both the intake and exhaust fans outdoors, the noise problem of air exchange and circulation is effectively solved. Based on the directional characteristics of airflow, the intake devices are placed on both sides of the lower interior, and the exhaust devices are placed at the top center of the interior, so that the fresh air circulation airflow enters from the bottom and exits from the top, enters from the sides and exits from the center. By controlling the movable exhaust pipes of the intake devices through several control ports, the exhaust angle can be controlled according to changes in room temperature, ensuring stable airflow circulation in the room and guaranteeing the circulation and exhaust effect.

[0018] The control mechanism includes a temperature sensor 16, a control unit 17, a pair of drive motors 18, and a pair of connecting shafts 19. The pair of drive motors are located on both sides of the extended air duct, and the pair of connecting shafts are located on both sides of the movable air outlet and connected to the drive motors. The temperature sensor is located on the extended air duct and connected to the drive motors through the control unit.

[0019] The control mechanism includes a temperature sensor, a control unit, a pair of drive motors, and a pair of connecting shafts. The pair of drive motors are located on both sides of the extended air duct, and the pair of connecting shafts are located on both sides of the movable air outlet duct and connected to the drive motors. The temperature sensor is located on the extended air duct and connected to the drive motors through the control unit. The room temperature measured by the temperature sensor is fed back to the control unit, and then the drive motors control the rotation of the movable air outlet duct, so that the movable air outlet duct can deliver air into the room at different angles under different room temperatures, thereby improving the coverage efficiency of indoor ventilation.

[0020] The extended air duct is provided with several airflow guiding baffles 20 located near the movable air outlet pipe. The several airflow guiding baffles are evenly arranged on the upper and lower inner walls of the extended air duct.

[0021] Because the extended air duct is equipped with several airflow guiding baffles located near the movable air outlet pipe, and these baffles are evenly arranged on the upper and lower inner walls of the extended air duct, the baffles can guide the airflow while also increasing the flow length of the airflow. This allows the dust carried by the airflow to adhere to the surface of the baffles, thus achieving a certain filtering effect.

[0022] The extended air duct has cleaning ports 21 on both sides of the uniform air outlet plate, and a detachable cover plate 22 is provided on the cleaning port. A portion of several airflow guiding baffles is located below the cover plate.

[0023] Since the extended air duct has cleaning ports on both sides of the uniform air outlet plate and a removable cover plate on the cleaning port, and a portion of several airflow guiding baffles are located below the cover plate, the extended air duct can be easily and quickly disassembled to clean the inside of the extended air duct, avoiding the problem of poor circulation effect caused by dust accumulation after long-term use.
