The exhaust air volute 23 is provided with an exhaust air fan 231 and a second driving motor 232, the second driving motor 232 drives the exhaust air fan 231 to rotate to generate air power towards the exhaust air outlet 22.

[0026] In this embodiment, the exhaust return air vent 21, the exhaust air outlet 22 and the fresh air inlet 31 are arranged side by side on the same side 14 (front side wall 14) of the shell 1, so that the partition 13 can be better used to isolate the exhaust area 2 and the fresh air area 3 in actual assembly, and the exhaust air outlet 22 and the fresh air inlet 31 are on the same side, which is also conducive to the simultaneous arrangement of a ventilation pipe extending to the outdoors; an air vent assembly 15 is provided on the outside of the side 14, and the air vent assembly 15 is provided with three vents 151a, 151b, and 151c side by side, which are connected to the exhaust return air vent 21, the exhaust air outlet 22 and the fresh air inlet 31 respectively. The air inlets 31 are connected one by one. As shown in the figure, the vent 151a is connected to the fresh air inlet 31, the vent 151c is connected to the exhaust return air vent 21, and the vent 151b is connected to the exhaust outlet 22. The three vents 151a, 151b, and 151c can be provided with air valves to control and limit the air volume passing through each vent. In actual applications, the exhaust outlet 22 and the fresh air inlet 31 are further connected through a ventilation pipe extending to the outdoors, generally using a copper pipe.

[0030] In actual application, the fresh air outlet 35 is arranged on the side wall (left side wall panel 18a) diagonally opposite to the fresh air inlet 31 in the inner cavity 12, as shown in the figure, to ensure that the fresh air inlet 31, the fresh air inlet channel 32, and the fresh air outlet channel 36 form a whole passage 4 that runs through the inner cavity 12, so that the fresh air entering the module and the passage 4 coming out after passing through the inner cavity 12 are long enough, and have enough time to pass through the filtering structure 33 for filtration and purification, thereby generating clean fresh air to enter the room.

[0031] like Figure 5 As shown, the patent can be assembled on the central air conditioner indoor unit 5 and installed and used with the whole machine (indoor unit + outdoor unit); in actual application, such as Figure 3 As shown, according to the direction indicated by the arrow in the figure, the first drive motor 342 in the fresh air zone 3 drives the fresh air impeller 341 to rotate, guiding the outdoor fresh air from the fresh air inlet 31 into the fresh air inlet duct 32, passing through the coarse-effect filter 331 and the high-efficiency filter 332, and then passing through the fresh air outlet duct 36 (the air duct in the fresh air volute 34), and finally blowing into the room through the fresh air outlet 35;

[0032] The second drive motor 232 in the exhaust zone 2 drives the exhaust impeller 231 to rotate, introducing the indoor air from the exhaust return air port 21 into the exhaust zone 2, passing through the exhaust outlet duct 24 (the air duct inside the exhaust volute 23), and finally discharged to the outside through the exhaust outlet 22; the fresh air zone 3 and the exhaust zone 2 can work at the same time, or they can be controlled and driven separately to work by their motors.

[0033] This patented device has a simple structure and is easy to use. It can be used in conjunction with an air conditioner indoor unit or as a fresh air fan alone. It can also be used in conjunction with some intelligent control modules and smart APPs to adjust the fresh air air conditioning mode, gear position, etc., to more accurately control indoor air quality.
