Specifically, when first air baffle 413 rotates towards air inlet cavity 331, first opening 415 can be opened; the second opening 416 can be opened when the second damper 414 is rotated into the wind tunnel 355. With such arrangement, when the first wind shield 413 rotates towards the air inlet cavity 331 to open the first opening 415, the first wind shield 413 can also guide fresh air to enter the air inlet cavity 331, so that the fresh air is efficiently and reliably introduced; similarly, when the second wind blocking plate 414 rotates toward the wind channel 355 to open the second opening 416, the second wind blocking plate 414 can guide the dirty wind to flow to the dirty wind outlet 356, thereby discharging the dirty wind efficiently and reliably.

In this embodiment, the first passage 411 and the second passage 412 can both convey gas in a set direction; by the arrangement, air conveyed by the first channel 411 does not need to be gathered to the second channel 412 for conveying, air conveyed by the second channel 412 does not need to be gathered to the first channel 411 for conveying, the condition of air conveying steering is reduced, the problem that air flow is blocked by channel walls when fresh air is introduced or dirty air is discharged can be reduced, and further air flow resistance is effectively reduced.

Further, referring to fig. 6 and 11, the housing 410 is further provided with a third channel 417, the first channel 411 and the second channel 412 are distributed side by side, and an outlet of the first channel 411 and an outlet of the second channel 412 are both communicated with the third channel 417. The first channel 411 and the second channel 412 are both communicated with the third channel 417, that is, only one pipeline is connected to the third channel 417, so as to introduce fresh air or discharge dirty air, thereby being beneficial to reducing the cost.

Still further, the third passageway 417 is configured to deliver gas in a set direction. The third duct 417 is also disposed to convey gas in a predetermined direction, so that the gas can smoothly flow between the first duct 411 and the third duct 417, or between the second duct 412 and the third duct 417, that is, when new air is introduced, the new air can be kept in a state of flowing in the predetermined direction in the housing 410, or when dirty air is discharged, the dirty air can be kept in a state of flowing in the predetermined direction in the housing 410, and the obstruction of the duct walls during air flow is reduced, thereby reducing air flow resistance, ensuring efficient air circulation, that is, ensuring efficient introduction of new air or discharge of dirty air.

The setting direction is the direction of the ab arrow in the figure.

To further ensure that each of the branch passages of the housing 410 can effectively reduce the air flow resistance; referring to fig. 6, the housing 410 is further provided with a first transition passage 418 and a second transition passage 419, the first passage 411 is communicated with the third passage 417 through the first transition passage 418, and the second passage 412 is communicated with the third passage 417 through the second transition passage 419; wherein the inner diameter of the first transition passage 418 is gradually reduced in a direction in which the gas flows from the first passage 411 to the third passage 417; in the direction of gas flow from second passage 412 to third passage 417, the inner diameter of second transition passage 419 gradually decreases, and first transition passage 418 and second transition passage 419 also deliver air generally in the set direction; the arrangement is such that the branch passages of the valve assembly 400 are substantially "Y" shaped. By providing the first transition passage 418 and the second transition passage 419 with variable diameters, air can be further ensured to flow efficiently in each passage of the valve assembly 400, and air flow resistance can be effectively reduced.

The work flow of the fresh air mechanism 200 in this embodiment includes:

introducing fresh air; rotating first air deflector 413 to open first opening 415 so that first channel 411 and fresh air inlet 332 communicate through first opening 415; rotating the second shutter 342 to close the second opening 416; the dirty air inlet 334 is closed by a baffle 342; the fan 320 is operated to introduce outdoor fresh air into the air inlet cavity 331 through the third channel 417, the first channel 411, the first opening 415 and the fresh air inlet 332, and after being filtered by the filter assembly 310, the fresh air enters the fan cavity 351 through the air inlet 333, and then is delivered to the indoor space through the air duct 355.

Discharging dirty air; rotating first windshield 413 closes first opening 415; rotating the second damper 414 opens the second opening 416 such that the second passage 412 communicates with the dirty air outlet 356; opening the dirty air inlet 334 with the damper 342; the blower 320 is operated to introduce indoor dirty air into the air inlet chamber 331 through the dirty air inlet 334, the dirty air directly enters the blower chamber 351 through the air inlet 333 without passing through the filter assembly 310, then enters the second channel 412 through the dirty air outlet 356 and the second opening 416 in sequence, and then enters the third channel 417 through the second channel 412 to be discharged.

To sum up, the fresh air mechanism 200 provided in the air conditioner 010 of the present invention can utilize the valve assembly 400 to realize the function of introducing fresh air or discharging dirty air; the air flow resistance of each branch channel of the valve assembly 400 is small, so that the introduction amount of fresh air and the discharge amount of dirty air can be ensured, and good user experience is ensured.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the scope or spirit of the present invention, and the scope of the present invention is defined by the appended claims.
