[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0023] The air treatment equipment provided by the embodiment of the utility model is as follows Figures 1 to 3 As shown, it includes: a main body 100, the main body 100 has a first air duct 110 and a second air duct 120, the first air duct 110 has a first air port 111, a common air port and a third air port 112 that can be opened and closed, the second air duct 120 has a common air port and a ninth air port 121 that can be opened and closed, and the common air port connects the first air duct 110 and the second air duct 120; a heat exchanger 200, the heat exchanger 200 is arranged in the second air duct 120; a first fan 300 and a second fan 400, the first fan 300 and the second fan 400 are both arranged in the first air duct 110 and share the same driving member 500 for driving operation, the first fan 300 has a fifth air port and a sixth air port 310, the second fan 400 has a seventh air port and an eighth air port 410, The fifth air outlet is arranged at the common air outlet and is connected to the second air duct 120 through the common air outlet, the seventh air outlet is connected to the third air outlet 112, the sixth air outlet 310 and the eighth air outlet 410 are both connected to the inside of the first air duct 110, in this scheme, the first air outlet 111 is connected to the sixth air outlet 310 of the first fan 300 through the first air duct 110, the fifth air outlet of the first fan 300 is connected to the second air duct 120 through the common air outlet, and the first fan 300 is configured to form a wind beam flowing from the first air outlet 111 through the first air duct 110 and the second air duct 120 to the ninth air outlet 121 based on operation, and the second fan 400 is configured to form a wind beam flowing from the first air outlet 110 through the first air duct 110 to the third air outlet 112 based on operation.

[0024] The first air vent 111 is a return air vent, the third air vent 112 is an outdoor air vent, and the ninth air vent 121 is an exhaust air vent. The first air vent 111 and the ninth air vent 121 are both connected to the indoor room, and the third air vent 112 is connected to the outdoors. The third air vent 112 is controlled to be turned off and the ninth air vent 121 is opened, and the driving member 500 drives the first fan 300 and the second fan 400 to operate. The first fan 300 forms a wind beam that flows from the first air vent 111 through the first air duct 110 and the second air duct 120 to the ninth air vent 121. At this time, the indoor air passes through the first air duct 110 and the second air duct 120 from the first air vent 111 in sequence, and is then discharged back to the room from the ninth air vent 121. During the process of the indoor air passing through the heat exchanger 200, heat is exchanged with the heat exchanger 200, so as to achieve indoor cooling or heating (i.e., air The air treatment equipment operates in heat pump mode, and performs cooling or heating through the heat pump function); the third air vent 112 is controlled to be opened and the ninth air vent 121 is closed, and the driving component 500 drives the first fan 300 and the second fan 400 to operate, and the second fan 400 forms a wind beam that flows from the first air vent 111 to the third air vent 112 through the first air duct 110. At this time, the indoor air enters the first air duct 110 from the first air vent 111, and is discharged to the outdoors from the third air vent 112, thereby realizing exhaust from the indoor to the outdoors (that is, the air treatment equipment operates in exhaust mode, and exhausts to the outdoors through the exhaust function).

[0025] The air treatment equipment has exhaust function and heat pump function, and the first fan 300 and the second fan 400 share the same driving member 500 for driving operation, so the structure is simpler and the manufacturing cost is lower.

[0026] In some examples, such as Figure 1 As shown, the wind wheel of the first fan 300 and the wind wheel of the second fan 400 are both transmission connected to the driving member 500, and along the first rotation direction of the driving member 500, the thrust surface (such as a concave curved surface) of the blades of the wind wheel of the first fan 300 and the suction surface (such as a convex curved surface) of the blades of the wind wheel of the second fan 400 are oriented in the same direction, and the suction surface (such as a convex curved surface) of the blades of the wind wheel of the first fan 300 and the thrust surface (such as a concave curved surface) of the blades of the wind wheel of the second fan 400 are oriented in the same direction.

[0027] For the technical solution in which the thrust surface of the blades of the wind wheel of the first fan 300 faces forward along the first rotation direction, and the thrust surface of the blades of the wind wheel of the second fan 400 faces backward along the first rotation direction: the driving member 500 drives the wind wheel of the first fan 300 and the wind wheel of the second fan 400 to rotate together along the first rotation direction, then the wind wheel of the first fan 300 rotates forward, and the wind wheel of the second fan 400 rotates reversely. At this time, the first fan 300 forms a wind beam with a particularly large air volume flowing from the first air outlet 111 to the ninth air outlet 121 through the first air duct 110 and the second air duct 120 in sequence due to its forward rotation of the wind wheel, and the second fan 400 Due to the reverse rotation of its wind wheel, a wind beam with a particularly small air volume is formed, which is suitable for air handling equipment operating in heat pump mode; the driving member 500 drives the wind wheel of the first fan 300 and the wind wheel of the second fan 400 to rotate in the opposite direction of the first rotation direction, so that the wind wheel of the first fan 300 is reversed and the wind wheel of the second fan 400 is forward rotating. At this time, the second fan 400 forms a wind beam with a particularly large air volume flowing from the first air outlet 110 through the first air duct 110 to the third air outlet 112 due to its forward rotation of the wind wheel, while the first fan 300 forms a wind beam with a particularly small air volume due to its reverse rotation of the wind wheel, which is suitable for air handling equipment operating in exhaust mode.

At this time, the wind wheel of the second fan 400 forms a particularly large wind beam flowing from the first air outlet 110 through the first air duct 110 to the third air outlet 112 due to its forward rotation of the wind wheel, and the wind wheel of the first fan 300 forms a particularly large wind beam due to its reverse rotation of the wind wheel. The driving member 500 drives the wind wheel of the first fan 300 and the wind wheel of the second fan 400 to rotate in the opposite direction of the first rotation direction, so that the wind wheel of the first fan 300 rotates forward and the wind wheel of the second fan 400 rotates reversely. At this time, the first fan 300 forms a wind beam with a particularly large air volume flowing from the first air outlet 111 through the first air duct 110 and the second air duct 120 to the ninth air outlet 121 due to its forward rotation of the wind wheel, and the second fan 400 forms a wind beam with a particularly small air volume due to its reverse rotation of the wind wheel, which is suitable for the air handling equipment to operate in the heat pump mode.

[0029] like Figures 1 to 3 As shown, the first fan 300, the second fan 400 and the driving member 500 are all located inside the first air duct 110, so that the air treatment device manufactured in this way has a smaller size and does not increase the installation space required indoors.

[0030] In some examples, such as Figures 1 to 3As shown, the first fan 300 includes a first volute and a first wind wheel arranged in the first volute, the fifth wind outlet and the sixth wind outlet 310 are located in the first volute, the second fan 400 includes a second volute and a second wind wheel arranged in the second volute, the seventh wind outlet and the eighth wind outlet 410 are located in the second volute, and the driving member 500 is connected to the first wind wheel and the second wind wheel by transmission. This solution has a simple structure and mature technology.

[0032] For the technical solution in which the thrust surface of the blades of the first wind wheel faces backward along the first rotation direction and the thrust surface of the blades of the second wind wheel faces forward along the first rotation direction: the driving member 500 drives the first wind wheel and the second wind wheel to rotate together along the first rotation direction, then the first wind wheel is in reverse rotation and the second wind wheel is in forward rotation, at this time the second fan 400 forms a wind beam with a particularly large air volume flowing from the first air outlet 110 through the first air duct 110 to the third air outlet 112, while the first fan 300 forms a wind beam with a particularly small air volume, which is suitable for the air handling equipment to perform an exhaust mode; the driving member 500 drives the first wind wheel and the second wind wheel to rotate in the opposite direction of the first rotation direction, then the first wind wheel is in forward rotation and the second wind wheel is in reverse rotation, at this time the first fan 300 forms a wind beam with a particularly large air volume flowing from the first air outlet 111 through the first air duct 110 and the second air duct 120 to the ninth air outlet 121 in sequence, while the second fan 400 forms a wind beam with a particularly small air volume, which is suitable for the air handling equipment to perform a heat pump mode.

Alternatively, the driving member 500 may be located between the first volute and the second volute, in which case the driving member 500 is configured as a double-shaft motor; or the driving member 500 may be located on the same side of the first volute and the second volute, in which case the driving member 500 is configured as a single-shaft motor.

[0037] In some further embodiments, Figure 1 As shown, the sixth air outlet 310 and the eighth air outlet 410 are arranged opposite to each other. Figure 1 As shown, the driving member 500 can be located between the sixth air outlet 310 and the eighth air outlet 410, in which case the driving member 500 is configured as a double-shaft motor, and the two output shafts of the double-shaft motor extend into the sixth air outlet 310 and the eighth air outlet 410, and are transmission-connected to the first wind wheel and the second wind wheel; or the driving member 500 can be located on the same side of the first volute and the second volute, in which case the driving member 500 is configured as a single-shaft motor.
