And, also can control the opening and closing or close of second fresh air inlet 32, make the new trend directly blow to indoor from new trend air outlet 12 directly for the loss and the resistance that receives of new trend reduce, are favorable to increasing the air supply scope of new trend, improve the circulating speed of indoor new trend, and the new trend air-out wind speed is low, and small in noise can be obvious improvement user experience.

As shown in fig. 4, the air conditioner indoor unit 100 further includes: the first air guiding assembly 40 is rotatably disposed on the first fresh air inlet 31, and when the first air guiding assembly 40 is opened, the heat exchange air duct 22 is communicated with the fresh air duct 30. That is to say, through setting up first wind guide assembly 40, can rotate first wind guide assembly 40 according to the user's demand and open first fresh air mouth 31, fresh air fan and heat exchange fan 23 all work this moment, and the fresh air that blows off from first fresh air mouth 31 can mix with the heat transfer wind in the heat transfer wind channel 22, makes the mixed wind blow indoor from heat transfer air outlet 11. Or, the first air guide assembly 40 is rotated to open the first fresh air port 31, the fresh air fan works, the heat exchange fan 23 does not work, and fresh air blown out from the first fresh air port 31 enters the heat exchange air duct 22 and can be independently blown into the room through the heat exchange air outlet 11.

Wherein, first wind guiding assembly 40 includes: the first driving member 41 and the first air guiding plate 42 are connected in a driving manner, and the first driving member 41 and the first air guiding plate 42 are rotatably disposed at the first fresh air inlet 31. The first driving member 41 can perform a driving function, and the first driving member 41 is in driving connection with the first air guiding plate 42, so that when the first driving member 41 drives the first air guiding plate 42 to rotate, the first air guiding plate 42 performs an air guiding function. And, by the rotation of the first air deflector 42, the first fresh air port 31 can be selectively opened or closed, for example, when the first air deflector 42 is closed, fresh air is not blown out through the first fresh air port 31, that is, fresh air can be blown out through the second fresh air port 32 and directly blown into the room from the fresh air outlet 12, or the indoor unit 100 of the air conditioner does not blow fresh air. For another example, when the first air deflector 42 is opened, the fresh air blower is turned on, and fresh air is blown to the heat exchange air duct 22 from the first fresh air outlet 31, and can be blown to the indoor from the heat exchange air outlet 11. In addition, when the new trend fan was opened, the new trend can also be followed second new trend mouth 32 and directly blown out to it is indoor directly to blow from new trend air outlet 12, owing to need not pass through other air-out passageways, the windage on the new trend route is little, and the new amount of wind is great.

That is to say, when the first air deflector 42 deflects towards the heat exchange air outlet 11, the fresh air blown out by the fresh air blower is blown out from the first fresh air outlet 31 and blown out towards the heat exchange air outlet 11 under the guidance of the first air deflector 42, and due to the action of the heat exchange fan 23, the fresh air in this mode is blown out into the heat exchange air duct 22 by the heat exchange fan 23 and can be blown out from the heat exchange air outlet 11 after passing through the heat exchanger 21, at this moment, the air blown out from the heat exchange air outlet 11 is mixed air, and the air supply direction of the mixed air can be adjusted for left and right air supply and up and down air supply, so that the influence of the introduced outdoor fresh air on the indoor temperature can be effectively improved, the range of mixed air release is wide, and the indoor circulation speed is faster.

It should be noted that the width of the first air deflector 42 is greater than or equal to the width of the first fresh air opening 31, so that the first air deflector 42 rotates towards the fresh air duct 30. If the first air deflector 42 rotates towards the heat exchange air duct 22, when the heat exchange air in the heat exchange air duct 22 is blown out, the heat exchange air may drive the first air deflector 42 to rotate reversely, so that the first air deflector 42 is closed, and the communication between the heat exchange air duct 22 and the fresh air duct 30 is affected, if the fresh air in the fresh air duct 30 enters the heat exchange air duct 22, because the first air deflector 42 has rotated into the fresh air duct 30, the influence of the fresh air on the first air deflector 42 is small, and interference cannot be generated on the first air deflector 42, so that only the fresh air in the fresh air duct 30 can enter the heat exchange air duct 22, and the heat exchange air in the heat exchange air duct 22 cannot enter the fresh air duct 30. In addition, the width of the first air deflector 42 is greater than or equal to the width of the first fresh air opening 31, so that when the first air deflector 42 is closed, the first fresh air opening 31 can be completely shielded, and the sealing reliability of the first fresh air opening 31 can be ensured.

In addition, as shown in fig. 4, the air conditioner indoor unit 100 further includes: the second air guiding assembly 50 and the second air guiding assembly 50 are rotatably disposed at the fresh air outlet 12 to selectively open or close the fresh air outlet 12. That is to say, through setting up second air ducting component 50, can rotate second air ducting component 50 according to user's demand and close fresh air outlet 12, the fresh air fan does not work this moment, or the new trend blows out from first fresh air inlet 31. Or when the second air guide assembly 50 opens the fresh air outlet 12, the fresh air fan is turned on, and the fresh air is directly blown out from the fresh air outlet 12, that is, the fresh air is discharged out, and because the fresh air does not need to pass through other air outlet channels, the air resistance on the fresh air path is small, the fresh air volume is large, and the use comfort of the user is improved.

Wherein, the second wind guiding component 50 includes: the second driving member 51 and the second air guiding plate 52 are connected in a driving manner, and the second driving member 51 is connected to the second air guiding plate 52, and the second air guiding plate 52 is rotatably disposed at the fresh air outlet 12. The second driving element 51 can perform a driving function, and the second driving element 51 is in driving connection with the second air guiding plate 52, so that when the second driving element 51 drives the second air guiding plate 52 to rotate, the second air guiding plate 52 performs an air guiding function. Through the rotation of the second air deflector 52, the fresh air outlet 12 can be selectively opened or closed, for example, when the second air deflector 52 is closed, the fresh air can be blown from the first fresh air outlet 31 to the heat exchange air duct 22, and blown from the heat exchange air outlet 11. For another example, when the second air deflector 52 is opened, the fresh air blower is turned on, and the fresh air is blown out downwards from the fresh air outlet 12, that is, a lower fresh air outlet mode is added to three separate air blowing modes of the fresh air.

Further, the housing 10 further includes: and the sliding door is movably arranged at the fresh air outlet 12. Thus, if the sliding door is closed, the second air guiding plate 52 is also in a closed state, and fresh air cannot be blown out from the fresh air outlet 12 at this time, and if the sliding door is opened, fresh air can be directly blown out from the fresh air outlet 12.

In addition, as shown in fig. 2 and 5, the indoor unit 100 of the air conditioner further includes: a third air deflection assembly, the third air deflection assembly comprising: the third driving member is in driving connection with the third air guiding plate 60, and the third air guiding plate 60 is rotatably disposed at the heat exchanging air outlet 11 so as to selectively open or close the heat exchanging air outlet 11. Similarly, the third driving part can play a driving role, the third driving part is in driving connection with the third air deflector 60, so the third driving part can drive the third air deflector 60 to rotate, thereby the third air deflector 60 can play a wind guiding role, the third air deflector 60 is rotationally arranged at the heat exchange air outlet 11, through the rotation of the third air deflector 60, the opening and closing of the heat exchange air outlet 11 can be realized, when the third air deflector 60 is closed, fresh air or heat exchange air, or mixed air of the fresh air and the heat exchange air cannot be released from the heat exchange air outlet 11, if the third air deflector 60 is opened, the fresh air can be introduced into the heat exchange air duct 22 and mixed with the heat exchange air, thereby the fresh air can be blown into the room from the heat exchange air outlet 11.

That is to say, the fresh air is converged and accelerated in the fresh air shell and then blown out from the fresh air main outlet on the fresh air shell, and can be blown out from the first fresh air opening 31, or blown out from the second fresh air opening 32, or blown out from the first fresh air opening 31 and the second fresh air opening 32. That is, at least part of the fresh air can directly blow out from the second fresh air port 32 after accelerating in the fresh air shell, so that the fresh air does not need to flow through the heat exchange air duct 22, the attenuation of the fresh air can be avoided, and the air outlet volume and the air outlet speed of the fresh air are larger.

Referring to fig. 4, the first fresh air inlet 31, the second fresh air inlet 32 and the fresh air outlet 12 are configured in a strip shape, so that the first fresh air inlet 31, the second fresh air inlet 32 and the fresh air outlet 12 are configured in a strip shape, the first fresh air inlet 31 and the second fresh air inlet 32 can increase the air output of fresh air, and the strip-shaped fresh air outlet 12 can effectively increase the left and right air supply range of the fresh air, which is beneficial to rapid indoor diffusion of the fresh air.

Moreover, the length of the fresh air outlet 12 is smaller than that of the heat exchange air outlet 11, and the width of the fresh air outlet 12 is smaller than that of the heat exchange air outlet 11. So, under the prerequisite of the air supply effect of guaranteeing the new trend, the length of new trend air outlet 12 is less than the length of heat transfer air outlet 11, and it is reasonable to set up like this, accords with the setting of new trend air outlet 12 on casing 10 to and the width of new trend air outlet 12 is less than the width of heat transfer air outlet 11, forms the air supply mode who uses heat transfer air outlet 11 as main air outlet, new trend air outlet 12 as supplementary air outlet.
