Optionally, the second damper 400 is a second butterfly damper, an isolation rib, a fourth stop rib 10b, a fifth stop rib 10c, and a sixth limit rib 10d are formed on the inner wall of the box 100, and the first flow channel 10e is isolated from the second flow channel by the isolation rib; the second air door 400 has a second pivot shaft 410 pivoted to the inner wall, and the isolation rib, the second internal circulation air inlet 150, the fourth stop rib 10b, the fifth stop rib 10c, the external circulation air inlet 130 and the sixth limit rib 10d are sequentially arranged in the second direction; the second damper 400 is used for being respectively matched with the isolation rib and the fifth stop rib 10c to close the first internal circulation air inlet 140 and open the external circulation air inlet 130; and the second air door 400 is used for being respectively matched with the fourth stop rib 10b and the sixth stop rib 10d to close the external circulation air inlet 130 and open the first internal circulation air inlet 140, and the second direction is the axial direction of the second pivot shaft 410. Compared with the cylindrical air door, the butterfly air door is relatively small in size and easy to install, and the assembling efficiency of the air inlet box can be improved.
Another aspect of the present application provides an air conditioner including the air inlet box provided herein.
The air conditioner provided by the embodiment of the application is realized by applying the air inlet box provided by the embodiment of the application, the air inlet box is provided with a first flow channel 10e for enabling circulating air to enter only through the first internal circulation air inlet 140, and fresh air enters only through the external circulation air inlet 130 into the second flow channel, so that the circulating air and the fresh air respectively flow through the air outlet, and because the first flow channel 10e and the second flow channel are mutually isolated in the box body 100, the flowing tracks of the fresh air and the circulating air are difficult to interfere with each other, so that the fresh air and the circulating air in the air flow entering the vehicle have a proper proportion.
Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
