Detailed Embodiments

[0015] Embodiments of the present utility model: As Figures 1 to 3As shown in the figure, an intelligent fresh air fan that is convenient for assembly includes a housing 1 and a housing cover 2. The housing 1 is a rectangular container with an open top. A partition 3 is provided inside the housing 1, and a heat exchange component 4 is arranged in the middle of the housing 1. The heat exchange component 4 divides the interior of the housing 1 into left and right sides. One side of the heat exchange component 4 cooperates with the side wall of the housing 1 through the partition 3 to form a fresh air inlet chamber 5 and an exhaust air outlet chamber 6, and the other side forms a fresh air outlet chamber 7 and an exhaust air inlet chamber 8. The housing 1 is provided with a fresh air inlet 9 communicated with the fresh air inlet chamber 5, an exhaust air inlet 10 communicated with the exhaust air inlet chamber 8, a fresh air outlet 11 communicated with the fresh air outlet chamber 7, and an exhaust air outlet 12 communicated with the exhaust air outlet chamber 6. The fresh air inlet 9, the exhaust air inlet 10, the fresh air outlet 11, and the exhaust air outlet 12 are respectively arranged at the four corners of the housing 1. The fresh air inlet chamber 5 and the fresh air outlet chamber 7 are communicated with the heat exchange component 4 to form a fresh air channel, and the exhaust air inlet chamber 8 and the exhaust air outlet chamber 6 are communicated with the heat exchange component 4 to form an exhaust air channel. A high-efficiency filter element 13 is installed in the fresh air inlet chamber 7, and a primary filter element 14 is installed in the exhaust air inlet chamber 8. A fresh air fan 15 and an exhaust fan 16 are respectively installed in the fresh air outlet chamber 7 and the exhaust air outlet chamber 6. When the fresh air fan 15 operates, outdoor air enters the fresh air inlet chamber 5 through the fresh air inlet 9, is filtered by the high-efficiency filter element 13, exchanges heat through the heat exchange component 4, enters the fresh air outlet chamber 7, and is discharged into the room from the fresh air outlet 11. When the exhaust fan 15 operates, indoor air enters the exhaust air inlet chamber 8 through the exhaust air inlet 10, is filtered by the primary filter element 14, exchanges heat through the heat exchange component 4, enters the exhaust air outlet chamber 6, and is discharged to the outside through the exhaust air outlet 12. Sealing strips 17 are arranged on the side wall of the housing 1 and the top of the partition 3. Each component such as the heat exchange component 4, the fresh air fan 15, the exhaust fan 16, the high-efficiency filter element 13, and the primary filter element 14 is installed in each chamber of the housing 1 from the open side of the housing 1. The housing 1 cannot be turned over. Finally, the housing cover 2 is covered on the open side of the housing 1 and fits and seals with the sealing strip 17 to seal and isolate each chamber, thus completing the assembly and improving the assembly efficiency.

[0016] As a preference, a chute 18 is provided inside the housing 1. The heat exchange component 4 includes a heat exchange core in the shape of a quadrangular prism that is slidably connected and matched with the chute 18. Air passes through from two opposite sides respectively to achieve heat exchange. A notch for the heat exchange component 4 to enter and exit is provided on the side wall of the housing 1, which is convenient for the installation, removal, and replacement of the heat exchange component 4.

[0017] As a preference, a chute one 19 is provided in the fresh air inlet chamber 5 and the exhaust air inlet chamber 8. The high-efficiency filter element 13 is slidably connected in the chute one 19 of the fresh air inlet chamber 5, and the primary filter element 14 is slidably connected in the chute one 19 of the exhaust air inlet chamber 8. A notch one for them to enter and exit is provided on the side wall of the housing 1. The high-efficiency filter element 13 and the primary filter element 14 enter and exit the housing 1 through the corresponding notch one, which is convenient for installation, removal, and replacement.

[0018] As an option, it includes a controller connected to the new fan 15 and the exhaust fan 16. Electric air valves 20 are provided at both the fresh air inlet 9 and the exhaust outlet 12. The electric air valves 20 are connected to the controller and controlled by the controller. When the fresh air machine is running, the electric air valves 20 open the fresh air inlet 9 and the exhaust outlet 12 respectively, allowing indoor and outdoor air to freely enter and exit. When it stops running, the fresh air inlet 9 and the exhaust outlet 12 are closed to prevent indoor and outdoor air from entering and exiting, which helps to maintain the stability of the indoor temperature and also prevents small animals, foreign objects, etc. from entering.

[0019] As an option, a PM2.5 sensor 21 is installed in the fresh air inlet chamber 5. The PM2.5 sensor 21 is located behind the high-efficiency filter element 13 and is connected to the controller. The PM2.5 sensor 2 monitors the air after passing through the high-efficiency filter element 13. If the PM2.5 concentration is too high, ventilation is meaningless, and the fresh air machine stops running or issues a warning.

[0020] As an option, a CO2 sensor 22 is installed in the exhaust air inlet chamber 8. The CO2 sensor 22 is connected to the controller. The CO2 sensor 22 monitors the CO2 concentration in the room. If the indoor CO2 concentration is too high, the fresh air machine automatically runs for ventilation to achieve intelligent control of the fresh air machine.

[0021] As an option, it includes a bypass valve 23. The bypass valve 23 is slidably connected in the chute 18 and is connected to the fresh air inlet chamber 5 and the fresh air outlet chamber 7. Several temperature sensors 24 are also provided in the housing 1. The bypass valve 23 and the temperature sensors 24 are connected to the controller. The temperature sensors 24 monitor the indoor and outdoor temperatures. In the case of a large temperature difference between indoor and outdoor, the bypass valve 23 is controlled to be in a closed state. When outdoor air enters the fresh air channel, it enters the room through the heat exchange core. When indoor air enters the exhaust air channel, it is discharged to the outside through the heat exchange core. The incoming and outgoing air exchanges heat when passing through the heat exchange core. In the case of a small temperature difference between indoor and outdoor, the bypass valve 23 is controlled to open. When outdoor air enters the fresh air channel, since the resistance is large when passing through the heat exchange core 2, it preferentially enters the room through the bypass valve 23. Even when the operating power of the new fan 15 is small, it still has a large air intake, achieving an energy-saving effect. Compared with the bypass valve 23 fixedly arranged in the housing 1, in this application, the bypass valve 23 is disassembled and assembled through the notch of the chute 18, which is more convenient.
