[0039] Combination Figure 1-3As shown, the embodiment of the present disclosure provides a fresh air air conditioner, including: an air supply box 100, an air outlet box 200 and an air duct assembly 300. The air supply box 100 has a fresh air inlet 110 connected to the outdoor environment on one side, and a fresh air outlet connected to the indoor environment on the other side; the air outlet box 200 is arranged on one side of the air supply box 100, and the air outlet box 200 has an exhaust air inlet 210 connected to the indoor environment on one side, and an exhaust air outlet 220 on the other side; the air duct assembly 300 has a first connecting port 310, a second connecting port 320, a third connecting port 330 and a fourth connecting port 340, the first connecting port 310 is connected to the exhaust air outlet 220, the second connecting port 320 is connected to the indoor environment, and the third connecting port 330 is connected to the outdoor environment. The fourth connecting port 340 is connected to the air supply box 100; wherein, when the second connecting port 320 is closed, the fourth connecting port 340 is closed, and the first connecting port 310 is connected to the third connecting port 330; when the second connecting port 320, the third connecting port 330 and the fourth connecting port 340 are all opened, the second connecting port 320 is connected to the first connecting port 310, and the third connecting port 330 is connected to the fourth connecting port 340; when the third connecting port 330 is closed, the second connecting port 320 is connected to the first connecting port 310 and at the same time is connected to the fourth connecting port 340.

[0040] With the fresh air air conditioner provided by the embodiment of the present disclosure, when the third connecting port 330 is closed, the first connecting port 310, the second connecting port 320 and the fourth connecting port 340 are connected, and the air outlet box 200 sucks the indoor air into the air outlet box 200 through the exhaust air inlet 210, and then discharges it into the air duct assembly 300 through the exhaust air outlet 220. Part of the air enters the air supply box 100 through the fourth connecting port 340, and mixes with the outdoor air sucked into the air supply box 100 through the fresh air inlet 110, thereby reducing the temperature difference between the gas in the air supply box 100 and the indoor gas, and reducing the indoor temperature fluctuation. Part of the indoor air is discharged into the room through the second connecting port 320, forming an indoor air internal circulation. When the first connecting port 310 is connected to the second connecting port 320, and the third connecting port 330 is connected to the fourth connecting port 340, the air outlet box 200 delivers indoor air into the room through the first connecting port 310 and the second connecting port 320, forming an indoor air internal circulation; and outdoor air can enter the air supply box 100 from the third connecting port 330 and the fourth connecting port 340, increasing the air intake of the air supply box 100, thereby increasing the air intake of indoor fresh air. When the second connecting port 320 is closed and the fourth connecting port 340 is closed, the air outlet box 200 discharges indoor air to the outside through the first connecting port 310 and the third connecting port 330, reducing the pressure difference between indoor and outdoor, thereby meeting the diverse ventilation needs of users.

[0041] It can be understood that after the third connecting port 330 is connected with the fresh air duct, it extends to the outdoors to be connected with the outdoor environment.

[0042] Optionally, the flow rate of the fourth connecting port 340 is less than the flow rate of the first connecting port 310. In this way, since the fourth connecting port 340 is connected to the air supply box 100, and the air supply box 100 has a fresh air inlet 110 connected to the outside. The main function of the fourth connecting port 340 is to increase the air intake volume and air intake area of ​​the air supply box 100, or to introduce indoor air into the air supply box 100 and mix it with the air in the air supply box 100. Therefore, the flow rate of the fourth connecting port 340 is set to be relatively small. The first connecting port 310 provides a passage for the air in the air outlet box 200 to be discharged, so the flow rate of the first connecting port 310 is relatively large.

[0043] Optionally, the first communication port 310 of the air duct assembly 300 is connected to the exhaust outlet 220 of the air outlet box 200 via a connecting pipe 400. In this way, one end of the connecting pipe 400 is connected to the first communication port 310, and the other end of the connecting pipe 400 is connected to the exhaust outlet 220 of the air outlet box 200, thereby increasing the layout distance between the air duct assembly 300 and the air outlet box 200, so that the position of the air duct assembly 300 can be more reasonably arranged in the fresh air air conditioner.

[0044] Combination Figure 2 As shown, optionally, the air duct assembly 300 includes: a tube body 350, a first rotating member 360 and a second rotating member 370. The tube body 350 has a first communication port 310, a second communication port 320, a third communication port 330 and a fourth communication port 340; the first rotating member 360 is disposed in the tube body 350 and is rotatably connected to the tube body 350; the second rotating member 370 is disposed in the tube body 350 and is rotatably connected to the tube body 350 to control the opening or closing of the fourth communication port 340; wherein, when the first rotating member 360 rotates to the first position, the second communication port 320 is closed; when the first rotating member 360 rotates to the second position, the first communication port 310 is connected to the second communication port 320, and the third communication port 330 is connected to the fourth communication port 340; when the first rotating member 360 rotates to the third position, the third communication port 330 is closed.

[0045] In this way, when the first rotating member 360 rotates to the first position, the second connecting port 320 is closed, and the second rotating member 370 closes the fourth connecting port 340. The third connecting port 330 is connected to the first connecting port 310, and is connected to the exhaust outlet 220 of the air outlet box 200. The air outlet box 200 then sucks the indoor air into the air outlet box 200 through the exhaust inlet 210, and then discharges it to the outside through the exhaust outlet 220, the first connecting port 310 and the third connecting port 330. The air supply box 100 sucks the outdoor air into the air supply box 100 through the fresh air inlet 110, and then sends it into the room through the fresh air outlet, so as to realize the function of sending the outdoor fresh air into the room and discharging the indoor air to the outside, thereby reducing the pressure difference between the indoor and outdoor air and improving the ventilation effect of the fresh air.

[0046] Combination Figure 2 As shown, when the first rotating member 360 rotates to the second position, the first rotating member 360 blocks the communication between the first connecting port 310 and the second connecting port 320 and the third connecting port 330 and the fourth connecting port 340, and the second rotating member 370 opens the fourth connecting port 340. The first connecting port 310 can be connected to the second connecting port 320, and the air outlet box 200 discharges the indoor air sucked through the exhaust air inlet 210 into the room through the exhaust air outlet 220, the first connecting port 310 and the second connecting port 320, thereby forming an indoor air internal circulation. The third connecting port 330 can also be connected to the fourth connecting port 340, and the air supply box 100 can inhale outdoor air through the fresh air inlet 110, and can also inhale outdoor air through the third connecting port 330 and the fourth connecting port 340, thereby increasing the air intake and air intake range of the air supply box 100. Even if the fresh air inlet 110 is blocked, the fresh air function of sending outdoor air into the room can be maintained through the third connecting port 330 and the fourth connecting port 340.

[0047] Combination Figure 3 As shown, when the first rotating member 360 rotates to the third position, the first rotating member 360 closes the third connecting port 330, the second rotating member 370 opens the fourth connecting port 340, and the first connecting port 310, the second connecting port 320 and the fourth connecting port 340 are connected. The air outlet box 200 discharges the indoor air sucked in through the exhaust inlet 210 into the tube body 350 through the exhaust outlet 220 and the first connecting port 310. Part of the indoor air in the tube body 350 is discharged into the room through the second connecting port 320, forming an indoor air internal circulation. Another part of the indoor air in the tube body 350 enters the air supply box 100 through the fourth connecting port 340, and the outdoor air sucked in by the fresh air inlet 110 in the air supply box 100 is mixed with the indoor air, so that the temperature difference between the mixed air and the indoor air is relatively small, reducing the fluctuation range of the indoor temperature and improving the comfort of the indoor space. In summary, more air circulation modes are realized to meet the diverse ventilation needs of users.

[0048] Optionally, when the first rotating member 360 rotates between the first position and the second position, the second connecting port 320 is connected to the third connecting port 330. In this way, the air outlet box 200 discharges the indoor air sucked in through the exhaust inlet 210 into the tube body 350 through the exhaust outlet 220 and the first connecting port 310. When the second rotating member 370 closes the fourth connecting port 340, part of the air in the tube body 350 is discharged into the room through the second connecting port 320 to form an indoor-indoor circulation, and another part of the air in the tube body 350 is discharged to the outside through the third connecting port 330. Thereby, more air circulation modes are realized to meet the diverse ventilation needs of users.

[0049] Optionally, the opening direction of the second communication port 320 is the same as the opening direction of the third communication port 330, and opposite to the opening direction of the first communication port 310. In this way, the flow direction of the air flowing into the first communication port 310 is toward the second communication port 320 and the third communication port 330, so that the air in the tube body 350 is more easily discharged from the second communication port 320 and the third communication port 330, reducing the loss of air volume.

[0050] Combination Figure 3 As shown, optionally, a position-avoiding groove 351 is provided on the tube body 350 to provide space for the second rotating member 370 to rotate. In this way, by providing the position-avoiding groove 351, the rotatable angle of the second rotating member 370 is increased.

[0051] Exemplarily, a switch valve body such as a solenoid valve may be disposed at the first communication port 310 , the second communication port 320 , the third communication port 330 , and the fourth communication port 340 to control the closing or opening of the corresponding communication port.

[0052] Combination Figure 4 and Figure 5 As shown, optionally, the first rotating member 360 includes: a first rotating plate 361. One end of the first rotating plate 361 is rotatably connected to the inner side wall of the tube body 350. In this way, the first rotating plate 361 rotates in the tube body 350, and when the first rotating plate 361 rotates to the first position, the second rotating plate 371 can close the second communication port 320. When the first rotating plate 361 rotates to the second position, the first rotating plate 361 can block the communication between the first communication port 310 and the second communication port 320 and the third communication port 330 and the fourth communication port 340. When the first rotating plate 361 rotates to the third position, the first rotating plate 361 can close the third communication port 330, and the second rotating member 370 opens the fourth communication port 340, and the first communication port 310, the second communication port 320 and the fourth communication port 340 are connected.

[0053] Optionally, a first rotating shaft 362 is provided at one end of the first rotating plate 361, the first rotating shaft 362 is rotatably connected to the inner wall of the tube body 350, and one end of the first rotating shaft 362 passes through the tube body 350. In this way, the first rotating shaft 362 is rotatably connected to the inner wall of the tube body 350, and the stability of the connection between the first rotating shaft 362 and the tube body 350 is higher.

[0054] Optionally, the second rotating member 370 includes a second rotating plate 371. One end of the second rotating plate 371 is rotatably connected to the inner wall of the tube body 350. In this way, the second rotating plate 371 rotates in the tube body 350 to control the closing or opening of the fourth communication port 340, and cooperates with the first rotating member 360 to achieve more air circulation modes to meet the diverse ventilation needs of users.

[0055] Combination Figure 6 As shown, optionally, a second rotating shaft 372 is provided at one end of the second rotating plate 371, and the second rotating shaft 372 is rotatably connected to the inner side wall of the tube body 350, and one end of the second rotating shaft 372 passes through the tube body 350. In this way, the second rotating shaft 372 is rotatably connected to the inner side wall of the tube body 350, and the stability of the connection between the second rotating shaft 372 and the tube body 350 is higher.

[0056] Combination Figure 7 and Figure 8 As shown, optionally, a driving member 500 is provided on one side wall of the tube body 350 to drive the first rotating member 360 and the second rotating member 370 to rotate. In this way, the driving member 500 provides power for the first rotating member 360 and the second rotating member 370 to rotate, the driving member 500 drives the first rotating member 360 to rotate in the tube body 350, and the driving member 500 drives the second rotating member 370 to rotate in the tube body 350 and cooperate with the first rotating member 360, so as to realize more air circulation modes and meet the diverse ventilation needs of users.

[0057] Combination Figure 7As shown, in one embodiment, the driving member 500 includes: a driving motor 510 and a gear box 520. One side wall of the gear box 520 is connected to the driving motor 510, and the other side wall is connected to the tube body 350; wherein, the gears in the gear box 520 are respectively connected to the first rotating member 360 and the second rotating member 370, and the output shaft of the driving motor 510 extends into the gear box 520 to drive the first rotating member 360 and the second rotating member 370 to rotate. In this way, the driving motor 510 drives the first rotating member 360 and the second rotating member 370 to rotate synchronously through the gear box 520, and when the first rotating member 360 rotates to the first position, the second rotating member 370 closes the fourth communication port 340. When the first rotating member 360 rotates to the second position, the second rotating member 370 rotates synchronously and opens the fourth communication port 340. When the first rotating member 360 rotates to the third position, the second rotating member 370 rotates synchronously so that the fourth communication port 340 is in an open state. Thus, more air circulation modes are realized to meet the diverse ventilation needs of users.

When the first rotating plate 361 rotates to the second position, the second rotating plate 371 rotates synchronously and opens the fourth connecting port 340. When the first rotating plate 361 rotates to the third position, the second rotating plate 371 rotates synchronously so that the fourth connecting port 340 is in an open state. In this way, more air circulation modes are realized to meet the diverse ventilation needs of users.

[0059] Combination Figure 8 As shown, in another embodiment, the driving member 500 includes: a second motor 530 and a third motor 540.
