Of course, the application is not limited thereto; in other examples, in the fresh air mode, when the fresh air fan 32 is turned on, the indoor fan 2 is turned off, and the outlet 13 is turned on, outdoor fresh air flows into the second air duct from the fresh air inlet 31a and flows into the fresh air outlet 31b, then fresh air flows into the communication cavity 4a from the first communication port 4b and flows into the first air duct 11 from the second communication port 4c, and outdoor fresh air can be sent into the room, so that indoor and outdoor air circulation is realized, and quality and freshness of indoor air are improved, so that comfort of a user is improved.

Illustratively, in both the fresh air mode and the exhaust mode, the position corresponding to the air outlet side of the fresh air fan 32 is always communicated with the first communication port 4b, the position corresponding to the air outlet side of the indoor fan 2 is always communicated with the second communication port 4c, at this time, the switching between the fresh air mode and the exhaust mode can be achieved by whether the fresh air fan 32 and the indoor fan 2 are operated or not, in the fresh air mode, the fresh air fan 32 is turned on, at this time, the indoor fan 2 can be turned on or off, and in the exhaust mode, the fresh air fan 32 is turned off and the indoor fan 2 is turned on.

For example, in the normal air supply mode, referring to fig. 6 to 8, the indoor fan 2 is turned on, the fresh air fan 32 is turned off, and indoor air enters the first duct 11 from the indoor air inlet 12 and is sent out from the outlet 13, thereby realizing indoor air circulation (e.g., cooling or heating cycle).

Optionally, the number, opening size, opening shape, etc. of the second communication openings 4c formed by the communication structure 4 are not limited, for example, the second communication openings 4c may be multiple, and the second communication openings 4c are micropores, and the multiple second communication openings 4c are communicated with the first air duct 11, so that fresh air flow in the communication cavity 4a flows into the first air duct 11 through the multiple second communication openings 4c or indoor air flow in the first air duct 11 flows into the communication cavity 4a through the multiple second communication openings 4c, so that smoothness of air flow is ensured, and foreign matters (such as worms, etc.) are prevented from entering the communication cavity 4a through the second communication openings 4c to affect the operation of the fresh air fan 32. For example, the second communication port 4c may have one, two or more than two; the second communication port 4c may be circular, elliptical, polygonal, or the like.

According to the air conditioner indoor unit 100 provided by the embodiment of the utility model, the air flow induced by the fresh air fan 32 can be sent into the room from the second communication port 4c through the communication cavity 4a of the communication structure 4 to realize the fresh air mode of the air conditioner indoor unit 100, so that the outdoor fresh air can be sent into the room from the outside, the indoor air circulation is realized, and the freshness and the comfort of the indoor air are improved; the air current that indoor fan 2 induced can be through the intercommunication chamber 4a and the new trend part 3 of communication structure 4 in order to send indoor air outdoor, realizes the mode of airing exhaust of air conditioning indoor set 100 to can be with indoor turbid air from indoor to outdoor, realize indoor outer air cycle, reduce the turbidity of indoor air, improve the travelling comfort of indoor air. Thus, the indoor unit 100 has multiple operation modes to better adapt to different use situations and meet the differentiation requirements.

It can be understood that the setting position of the fresh air component 3 is not particularly limited, and can be particularly set according to actual requirements; for example, the fresh air component 3 may be disposed within the enclosure 1, or at least a portion of the fresh air component 3 may be disposed outside the enclosure 1.

In some embodiments, at least part of the communication structure 4 is disposed in the first air duct 11, such that the second communication port 4c is located in the first air duct 11 and the second communication port 4c is located on the air outlet side of the indoor fan 2; when the fresh air mode is adopted, if the indoor fan 2 is started, indoor air flow in the first air channel 11 can be well mixed with fresh air flow flowing out of the second communication port 4c, so that the mixed air flow temperature is more uniform, if the indoor fan 2 is closed, fresh air flow flowing out of the second communication port 4c can flow out of the outlet 13, and meanwhile, when the air exhaust mode is adopted, indoor air flow in the first air channel 11 can well flow into the second communication port 4c, so that air exhaust is smoother.

Further, the at least part of the communication structure 4 disposed in the first air duct 11 may be disposed adjacent to the outlet 13, which is beneficial for reducing the blocking effect of the communication structure 4 on the air flow in the first air duct 11.

In some embodiments, as shown in fig. 2, the communication structure 4 is disposed on the casing 1 and the communication structure 4 participates in defining a part of the wall surface of the first air duct 11, so that the second communication port 4c is located on the air outlet side of the indoor fan 2, and the communication structure 4 is convenient to be disposed, and meanwhile, the communication structure 4 is convenient to avoid that the air flow in the first air duct 11 is greatly blocked by the air flow in the first air duct 11 to influence the flow of the air flow, so that the smoothness of the air flow is ensured.

For example, in the example of fig. 2, in the air flow direction of the first air duct 11, the communication structure 4 is located at a downstream section of the first air duct 11 and is disposed adjacent to the outlet 13, and a portion of the wall surface of the communication structure 4 that participates in defining the first air duct 11 is formed with a plurality of second communication ports 4c, each of which second communication ports 4c communicates with the communication chamber 4a.

In some embodiments, as shown in fig. 10, in the exhaust mode, the outlet 13 is closed, the air outlet resistance at the outlet 13 is larger, and the air outlet resistance in the communication cavity 4a is smaller, so that more indoor air flows from the second communication port 4c to the communication cavity 4a and is discharged from the fresh air inlet 31a of the housing 31 to the outside, so that indoor air is discharged from the outside against resistance (such as blocking of the fresh air fan 32, etc.), thereby ensuring smoothness of indoor exhaust and being beneficial to improving exhaust efficiency.

In some embodiments, as shown in fig. 11-13, the communication structure 4 extends along the length direction (e.g., the left-right direction in fig. 1) of the outlet 13, and the first communication port 4b is formed at one end of the length of the communication structure 4, so that the air outlet side of the fresh air fan 32 is communicated with the first communication port 4b, and meanwhile, the fresh air component 3 may be disposed on one side of the length direction of the communication structure 4, so that the fresh air component 3 is convenient to be disposed, so that the fresh air component 3 is not easy to block the airflow at the outlet 13.

In addition, the length direction of the communication structure 4 is consistent with the length direction of the outlet 13, the first communication port 4b is located at one end of the length of the communication structure 4, and the communication structure 4 may be formed as a hollow structure, so that the peripheral side wall of the communication structure 4 provides a suitable arrangement area for the second communication port 4c, so as to achieve a suitable air intake in the fresh air mode and a suitable air exhaust efficiency in the air exhaust mode. Illustratively, the communication structure 4 is disposed at the outlet 13, and a second communication port 4c is formed on a side wall of the communication structure 4 facing the outlet 13, in the fresh air mode, the air flow induced by the fresh air fan 32 flows out through the second communication port 4c and flows into the outlet 13, so as to shorten the length of the flow path of the fresh air in the first air duct 11, reduce the fresh air resistance, and in the exhaust mode, the outlet 13 can be closed, so that at least a majority of the air flow induced by the indoor fan 2 flows to the fresh air component 3 through the second communication port 4c and is discharged outdoors.

Alternatively, one end of the communication structure 4 remote from the first communication port 4b (i.e., the other end of the length of the communication structure 4) is disposed in a closed manner.

In some embodiments, as shown in fig. 8 and 12, the outlets 13 are multiple and the multiple outlets 13 include a first outlet 13a and a second outlet 13b, the first outlet 13a is located above the second outlet 13b, the communication structure 4 is disposed between the first outlet 13a and the second outlet 13b, the communication structure 4 has a first side wall 41 disposed toward the first outlet 13a and a second side wall 42 disposed toward the second outlet 13b, the first side wall 41 is spaced apart from a portion of the wall of the first air duct 11 to define the first outlet 13a, and the second side wall 42 is spaced apart from a portion of the wall of the first air duct 11 to define the second outlet 13b; at this time, the first side wall 41 and the second side wall 42 may participate in defining a portion of the wall surface of the first air duct 11, so as to weaken the blocking of the air flow in the first air duct 11 by the communication structure 4.

Wherein, a second communication port 4c is formed on at least one of the first side wall 41 and the second side wall 42, the second communication port 4c communicates with the first air duct 11 and the communication chamber 4a, so that indoor air flow can flow from the first air duct 11 into the communication chamber 4a through the second communication port 4c, or fresh air flow can flow from the communication chamber 4a into the first air duct 11 through the second communication port 4 c.

For simplicity of description, the second communication port 4c is formed in both the first side wall 41 and the second side wall 42, which will be described later. It is understood that the second communication ports 4c formed in both the first side wall 41 and the second side wall 42 can increase the flow area of the air flow, and improve the efficiency and the air flow rate of the air flow.

Alternatively, the positions of the first outlet 13a and the second outlet 13b on the cabinet 1 are not limited, for example, in connection with fig. 8, the first outlet 13a and the second outlet 13b may be both located at the front side of the air conditioning indoor unit 100 and disposed at an upper and lower interval, or the first outlet 13a may be located at the front side of the air conditioning indoor unit 100 and the second outlet 13b may be located at the lower side of the air conditioning indoor unit 100.

In some embodiments, as shown in fig. 8, the first air duct 11 has a first branch 11a and a second branch 11b located at two sides of the communication structure 4, where the first branch 11a is connected to the first outlet 13a, and the second branch 11b is connected to the second outlet 13b, so that the air flow in the first air duct 11 can be split into the first branch 11a and the second branch 11b, where the air flow in the first branch 11a is sent out from the first outlet 13a, and the air flow in the second branch 11b is sent out from the second outlet 13 b. It can be seen that the first side wall 41 participates in defining the wall of the first branch 11a and the second side wall 42 participates in defining the wall of the second branch 11 b.

The air conditioning indoor unit 100 further includes a control unit 5, where the control unit 5 is configured to control on/off of the first branch 11a and the second branch 11b, and the air conditioning indoor unit 100 further has a first air outlet mode and a second air outlet mode.

In the first air outlet mode, the first branch 11a is turned on and the second branch 11b is turned off, the air flow in the first air duct 11 can flow out from the first outlet 13a through the first branch 11a, and the air flow in the first air duct 11 cannot flow out from the second outlet 13b through the second branch 11 b; in the second air-out mode, the first branch 11a is disconnected and the second branch 11b is turned on, the air flow in the first air duct 11 can flow out from the second outlet 13b through the second branch 11b, and the air flow in the first air duct 11 cannot flow out from the first outlet 13a through the first branch 11 a. Therefore, the air conditioning indoor unit 100 can switch different air outlet modes to change the air supply area of the air conditioning indoor unit 100 so as to adapt to the requirements of users.

Alternatively, the first air outlet mode and the second air outlet mode of the indoor unit 100 may be performed together with the fresh air mode, or the first air outlet mode and the second air outlet mode may be performed together with the normal air supply mode.

For example, the air conditioning indoor unit 100 may jointly perform a first air outlet mode and a fresh air mode, and in combination with fig. 6, the control unit 5 disconnects the second branch 11b and turns on the first branch 11a, the indoor fan 2 and the fresh air fan 32 are turned on, the indoor air flow enters the first air duct 11 and flows to the first branch 11a, the fresh air flow enters the first branch 11a and the second branch 11b from the second communication port 4c, the indoor air flow and the fresh air flow are mixed in the first branch 11a and sent out from the first outlet 13a, and in this mode, the indoor fan 2 may also be turned off; the air conditioning indoor unit 100 may perform the second air outlet mode and the fresh air mode together, and in combination with fig. 7, the control unit 5 disconnects the first branch 11a and turns on the second branch 11b, the indoor fan 2 and the fresh air fan 32 are turned on, the indoor air flow enters the first air duct 11 and flows to the second branch 11b, the fresh air flow enters the first branch 11a and the second branch 11b from the second communication port 4c, the indoor air flow and the fresh air flow are mixed in the second branch 11b and sent out from the second outlet 13b, and in this mode, the indoor fan 2 may also be turned off.

Alternatively, the air conditioning indoor unit 100 may perform the air discharge mode when the control part 5 is used to control the on-off of the first branch 11a and the second branch 11 b.

For another example, referring to fig. 2, the second side wall 42 is formed with a plurality of second communication ports 4c, the second communication ports 4c communicating with the second branch 11b; when the fresh air fan 32 is turned off and the indoor fan 2 is turned on, the control part 5 cuts off the first branch 11a and turns on the second branch 11b, indoor air enters the first air duct 11 from the indoor air inlet 12 and flows to the second branch 11b, indoor air flows enter the communication cavity 4a from the plurality of second communication ports 4c of the second side wall 42 and flows to the first communication port 4b, then indoor air flows from the fresh air outlet 31b into the second air duct and flows to the fresh air inlet 31a, and rear indoor air flows from the fresh air inlet 31a to the outside so as to send indoor turbid air to the outside, thereby realizing indoor and outdoor air circulation, reducing the turbidity of indoor air and improving the comfort of indoor air.

In some embodiments, as shown in fig. 6 and 7, the control part 5 includes an air guiding assembly 51, where the air guiding assembly 51 is used to switch the first outlet 13a and the second outlet 13b, in a first air outlet mode, the air guiding assembly 51 closes the second outlet 13b and opens the first outlet 13a to disconnect the second branch 11b, and the first branch 11a is turned on, and in a second air outlet mode, the air guiding assembly 51 closes the first outlet 13a and opens the second outlet 13b to disconnect the first branch 11a and turn on the second branch 11b, so that the indoor unit 100 of the air conditioner controls to switch the first outlet 13a and the second outlet 13b to adapt to the corresponding air outlet mode; and/or, the control part 5 includes a switching component 52, where the switching component 52 is movably disposed on the communication structure 4, in the first air outlet mode, the switching component 52 closes the second branch 11b and opens the first branch 11a to disconnect the second branch 11b, and the first branch 11a is turned on, and in the second air outlet mode, the switching component 52 closes the first branch 11a and opens the second branch 11b to disconnect the first branch 11a and turn on the second branch 11b, so that the indoor unit 100 of the air conditioner controls to switch the first branch 11a and the second branch 11b to adapt to the corresponding air outlet mode.

In the description of the embodiments of the present application, the term "and/or" is merely an association relationship describing an association object, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

Thus, the air guide assembly 51 and/or the switching assembly 52 facilitate the air conditioner indoor unit 100 to switch the corresponding air outlet state, so that the air conditioner indoor unit 100 has different air supply effects.

Alternatively, the switching assembly 52 may be used to switch the inlet of the first branch 11a and the inlet of the second branch 11 b. For example, in the first air-out mode, the switching assembly 52 closes the inlet of the second branch 11b and opens the inlet of the first branch 11a, and in the second air-out mode, the switching assembly 52 closes the inlet of the first branch 11a and opens the inlet of the second branch 11 b.

That is, in the first air-out mode, if the switching component 52 closes the second branch 11b, there is no specific limitation on whether the air guiding component 51 closes the second outlet 13b, and the air guiding component 51 may close the second outlet 13b or open the second outlet 13b; in the first air outlet mode, if the air guiding assembly 51 closes the second outlet 13b, the switching assembly 52 is not particularly limited, and the switching assembly 52 may close the second branch 11b or open the second branch 11b.

That is, in the second air-out mode, if the switching component 52 closes the first branch 11a, whether the air guiding component 51 closes the first outlet 13a is not particularly limited, and the air guiding component 51 may close the first outlet 13a or open the first outlet 13a; in the second air outlet mode, if the air guiding assembly 51 closes the first outlet 13a, the switching assembly 52 is not particularly limited, and the switching assembly 52 may close the first branch 11a or open the first branch 11a.

In some embodiments, as shown in fig. 6 and 7, the air guide assembly 51 includes a first air guide plate 511 and a second air guide plate 512, the first air guide plate 511 is rotatably disposed at the first outlet 13a to switch the first outlet 13a, and the second air guide plate 512 is rotatably disposed at the second outlet 13b to switch the second outlet 13b; in the first air outlet mode, the second air deflector 512 closes the second outlet 13b, the first air deflector 511 opens the first outlet 13a, the air flow in the first air duct 11 is sent out from the first outlet 13a, in the second air outlet mode, the first air deflector 511 closes the first outlet 13a, the second air deflector 512 opens the second outlet 13b, and the air flow in the first air duct 11 is sent out from the second outlet 13 b. Of course, the movement modes of the first air guide plate 511 and the second air guide plate 512 are not limited to this rotation.

In some embodiments, as shown in fig. 6 and 7, the switching assembly 52 includes a switching air deflector 521, where the switching air deflector 521 includes a first end and a second end in the airflow direction of the first air duct 11, the second end is located on the downstream side of the first end, and the second end of the switching air deflector 521 is rotatably provided on the communication structure 4; in the first air outlet mode, the switching air deflector 521 rotates forward to close the second branch 11b and open the first branch 11a, and in the second air outlet mode, the switching air deflector 521 rotates reversely to close the first branch 11a and open the second branch 11b, so as to control the airflow of the first air duct 11 to flow to the first branch 11a or the second branch 11b.

Illustratively, a rotating groove is formed at the intersection position of the first side wall 41 and the second side wall 42, and the second end of the switching air deflector 521 is matched with the rotating groove, so as to avoid the rotation of the switching air deflector 521, and facilitate the smooth transition between the surface of one side of the thickness of the switching air deflector 521 and the first side wall 41, and the smooth transition between the surface of the other side of the thickness of the switching air deflector 521 and the second side wall 42.

For example, in the examples of fig. 6 and 7, the air conditioning indoor unit 100 further includes a scroll 7, the scroll 7 has a first air duct 11 therein, a part of a wall surface of the scroll 7 and the first side wall 41 define a first branch 11a, another part of a wall surface of the scroll 7 and the second side wall 42 define a second branch 11b, and the second end of the switching air deflector 521 is disposed in the rotating groove. In the first air outlet mode, the switching air deflector 521 rotates towards the lower side until the first end is abutted against the wall surface of the inlet of the second branch 11b, and the first end can be substantially flush with the lower wall surface of the portion of the first air duct 11 adjacent to the second branch 11b, at this time, the switching air deflector 521 closes the second branch 11b and opens the first branch 11a, the switching air deflector 521 is arranged near horizontally, and the upper surface of the switching air deflector 521 is in forward connection with the first side wall 41, so that the air flow flows forward to the first branch 11a, and the air flow is prevented from being blocked at the cooperation position of the second end and the first side wall 41. In the second air outlet mode, the switching air deflector 521 rotates towards the upper side until the first end is abutted against the upper side wall surface of the first air duct 11, at this time, the switching air deflector 521 closes the first branch 11a and opens the second branch 11b, the switching air deflector 521 is obliquely arranged, and one side surface of the switching air deflector 521 towards the second branch 11b is in sequence connection with the second side wall 42, so that the air flow is in sequence flow to the second branch 11b, and the interference of the air flow at the joint of the second end and the second side wall 42 is avoided.

In some embodiments, as shown in fig. 9, when the control part 5 includes the switching assembly 52, in the first air outlet mode, the first side wall 41 forms an angle α -15 ° or more and 45 ° or less with the horizontal direction, and a part of the wall surfaces of the first side wall 41 and the first branch 11a define the first outlet 13a, so that the first side wall 41 can guide the air flow direction in the first branch 11a, so that the air supply direction of the first outlet 13a can be blown forward horizontally or forward obliquely (such as obliquely upward or obliquely downward). Illustratively, α is-15 °, -10 °, 5 °, 12 °, 20 °, 35 °, 40 °, 45 °, or the like.

It should be noted that, in connection with fig. 9, -15 ° +.alpha.ltoreq.0 °, the first side wall 41 may guide the air flow of the first outlet 13a to blow down obliquely toward the front side, α=0°, the first side wall 41 may guide the air flow of the first outlet 13a to blow horizontally, 0 ° < α.ltoreq.45°, and the first side wall 41 may guide the air flow of the first outlet 13a to blow up obliquely toward the front side.

Wherein, when 0 DEG < alpha is less than or equal to 45 DEG, the first side wall 41 can guide the air flow of the first outlet 13a to blow in the direction of the front side in an inclined upward direction, so that the air flow of the air flow presents the effect of the awning sedimentation air supply. For example, in the first air outlet mode, the first outlet 13a of the air conditioning indoor unit 100 may throw air upwards, and if the air conditioning indoor unit 100 is used for cooling, a cold air backdrop sedimentation air supply effect may be presented, so that the problem of direct blowing of cold air in a room is improved, and user comfort is improved.

It will be appreciated that the first sidewall 41 may be planar or curved; when the first side wall 41 is a curved surface, on the cross section of the communication structure 4, the included angle between the tangent line at any point on the curve corresponding to the first side wall 41 and the horizontal direction is within the range of-15 ° to 45 °, and the cross section of the communication structure 4 is perpendicular to the length direction of the communication structure 4.

For example, the first air deflector 511 may direct the air flow at the first outlet 13a upwards, and may also exhibit a cold air curtain type sedimentation air supply effect if the indoor unit 100 is used for cooling, so as to improve the problem of direct blowing of cold air in a room.

In some embodiments, as shown in fig. 9, the second outlet 13b is located at the lower side of the indoor unit 100, the second side wall 42 has an angle β -45 ° or more and 45 ° or less with respect to the vertical direction, and a part of the wall surfaces of the second side wall 42 and the second branch 11b define the second outlet 13b, so that the second side wall 42 may guide the airflow direction in the second branch 11b, so that the air supply direction of the second outlet 13b may blow vertically downward or blow obliquely forward or backward downward. Illustratively, β may be-45 °, -40 °, -35 °, -30 °, -25 °, -20 °, -10 °, 0 °, 5 °, 15 °, 25 °, 30 °, 40 °, 45 °, etc.

It should be noted that, in conjunction with fig. 9, -45 ° +.β < 0 °, the second side wall 42 may guide the air flow of the second outlet 13b to blow downward obliquely toward the lower side, β=0°, the second side wall 42 may guide the air flow of the second outlet 13b to blow downward vertically, 0 ° < β+.45 °, and the second side wall 42 may guide the air flow of the second outlet 13b to blow forward obliquely toward the lower side.

Wherein when 0 DEG < beta < 45 DEG, the second side wall 42 can guide the air flow of the second outlet 13b to blow in a direction inclined forward toward the lower side, so that the air flow of the air supply presents the air supply effect of blowing to the ground. For example, in the second air outlet mode, the second outlet 13b of the air conditioning indoor unit 100 may supply air toward the ground, and if the air conditioning indoor unit 100 is used for heating, an air supply effect of upward flow of hot air may be presented, so that the flow of indoor hot air is accelerated, and user comfort is improved.

Optionally, when the control member 5 includes the air guiding assembly 51, the air guiding assembly 51 includes a second air guiding plate 512, and the second air guiding plate 512 is rotatably disposed at the second outlet 13b to switch the second outlet 13b, and the second air guiding plate 512 rotates relative to the second outlet 13b to guide the air supplying direction of the second outlet 13b to change the air supplying effect of the second outlet 13 b. For example, the second air guiding plate 512 may guide the air flow at the second outlet 13b downward, and if the indoor unit 100 is used for heating, an air supplying effect of upward flow of hot air may be also presented, so as to accelerate the flow of hot air in the room.

For example, in the third air outlet mode, referring to fig. 10, the first outlet 13a is located at the front side of the air conditioning indoor unit 100, the second outlet 13b is located at the lower side of the air conditioning indoor unit 100, the first branch 11a and the second branch 11b are both turned on, the air flow in the first air duct 11 is split into the first branch 11a and the second branch 11b, the first outlet 13a blows air towards the front side, and the second outlet 13b blows air towards the lower side, so that the first outlet 13a and the second outlet 13b blow air simultaneously, and the blowing directions are different, thereby increasing the blowing range of the air conditioning indoor unit 100, making the indoor air disturbance fast, being beneficial to accelerating the indoor air flow, avoiding the blowing air flow from blowing the user directly, and improving the comfort of the user.

Alternatively, the third air outlet mode of the air conditioning indoor unit 100 may be performed together with the fresh air mode, or the third air outlet mode may be performed together with the normal air supply mode. For example, the air conditioning indoor unit 100 may perform the third air outlet mode and the fresh air mode together to realize fresh air at the first outlet 13a and the second outlet 13 b.

For example, in the third air outlet mode and the fresh air mode, referring to fig. 10, the first branch 11a and the second branch 11b are both turned on, the indoor fan 2 and the fresh air fan 32 are turned on, the indoor air flow enters the first air duct 11 and is split into the first branch 11a and the second branch 11b, a part of the fresh air flow enters the first branch 11a from the second communication port 4c of the first side wall 41, and another part of the fresh air flow enters the second branch 11b from the second communication port 4c of the second side wall 42, and the indoor air flow and the fresh air flow are mixed in the first branch 11a and the second branch 11b and are sent out from the corresponding first outlet 13a and second outlet 13 b; in this mode, the indoor fan 2 may also be turned off.

For another example, in the third air outlet mode and the normal air supply mode, the first branch 11a and the second branch 11b are both turned on, the indoor fan 2 is turned on, the fresh air fan 32 is turned off, and the indoor air flow enters the first air duct 11 and is split into the first branch 11a and the second branch 11b, and is sent out from the corresponding first outlet 13a and second outlet 13 b.

In some embodiments, as shown in fig. 14 and 15, the communication structure 4 further has a third side wall 43 connected between the first side wall 41 and the second side wall 42, the third side wall 43 being formed with a third communication port 43a that communicates with the communication chamber 4a and is openable and closable; in the fresh air mode, the third communication port 43a is opened, the air outlet range of the fresh air flow can be increased, the air volume of the fresh air can be increased, and in the air exhaust mode, the third communication port 43a is closed, so that the air conditioner indoor unit 100 can exhaust air.
