Connecting both the first channel 411 and the second channel 412 to the third channel 417 means that only one pipe is connected to the third channel 417 for introducing fresh air or exhausting dirty air, which is beneficial to reduce costs.

Still further, the third channel 417 is configured to deliver gas in a set direction. The third channel 417 is also configured to deliver gas in a set direction, so that the gas can flow smoothly between the first channel 411 and the third channel 417, or between the second channel 412 and the third channel 417 flow, that is, when the fresh air is introduced, the fresh air can be kept in the state of flowing in the set direction in the casing 410, or when the dirty air is discharged, the dirty air can be kept in the state of flowing in the set direction in the casing 410, reducing When the air flows, it is blocked by the channel wall, thereby reducing the air flow resistance to ensure efficient air circulation, which can ensure efficient fresh air introduction or dirty air discharge.

It should be noted that the setting direction is the direction of arrow ab in the figure.

In order to further ensure that each branch channel of the housing 410 can effectively reduce the air flow resistance; please refer to FIG. The channel 418 communicates with the third channel 417, and the second channel 412 communicates with the third channel 417 through the second transition channel 419; wherein, along the direction of the gas flowing from the first channel 411 to the third channel 417, the inner diameter of the first transition channel 418 Gradually decrease; along the direction of gas flow from the second channel 412 to the third channel 417, the inner diameter of the second transition channel 419 gradually decreases, and the first transition channel 418 and the second transition channel 419 also generally deliver air along the set direction ; So set, so that the branch channel of the valve assembly 400 is roughly "Y" shape. The setting of the first transition passage 418 and the second transition passage 419 with reduced diameters can further ensure that the air flows efficiently in each passage of the valve assembly 400 and effectively reduce the air flow resistance.

The working process of the fresh air mechanism 200 in the present embodiment includes:

Introduce fresh air; turn the first windshield 413 to open the first opening 415, so that the first passage 411 and the fresh air inlet 332 are communicated through the first opening 415; turn the second baffle 342 to close the second opening 416; utilize the baffle 342 to seal the dirt Air inlet 334; the fan 320 works 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 enters the fan cavity through the air inlet 333 after being filtered by the filter assembly 310 351, and then transported to the room from the air duct 355.

Exhaust the dirty wind; turn the first windshield 413 to close the first opening 415; turn the second windshield 414 to open the second opening 416, so that the second passage 412 communicates with the dirty wind outlet 356; use the baffle 342 to open the dirty wind inlet 334; the fan 320 works to introduce the indoor dirty air into the air inlet cavity 331 through the dirty air inlet 334, the dirty air does not pass through the filter assembly 310, directly enters the fan chamber 351 through the air inlet 333, and then passes through the dirty air outlet 356 and the second opening 416 in sequence Enter the second channel 412, and then enter the third channel 417 from the second channel 412 to be discharged.

To sum up, the fresh air mechanism 200 equipped with the air conditioner 010 of the present utility model can use the valve assembly 400 to realize the function of introducing fresh air or discharging dirty air; wherein, the air flow resistance of each branch channel of the valve assembly 400 is small, which can ensure fresh air flow. The amount of introduction and the discharge of dirty air ensure a good user experience.

Although the utility model is disclosed as above, the utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model, so the protection scope of the present utility model should be based on the scope defined in the claims.
