[0027] The indoor unit of the air conditioner and the air conditioner provided by the embodiment of the present disclosure can achieve the following technical effects:

[0028] The indoor unit of the air conditioner includes a housing, a first fan, a second fan, a heat exchanger and an air duct switching component. The housing is provided with an air inlet, and a front air outlet is provided at the upper part of the housing, and a side air outlet is provided at the side part of the housing; the first fan is communicated with the front air outlet and is used for sending air forward; the second fan is communicated with the side air outlet and is used for sending air to the side; the heat exchanger includes a first heat exchange part and a second heat exchange part, and the air after heat exchange with the second heat exchange part is sent out from the side air outlet after passing through the second fan; the air duct switching component is disposed between the first heat exchange part and the first fan, and the air duct switching component can be in a blocking state and a conducting state.

[0030] It can be seen that for the air conditioner indoor unit provided by the embodiments of the present disclosure, when only the side air outlet is required for air supply, the heat or cold generated by the first heat exchange part of the heat exchanger will not remain in the heat exchanger, but is sent out from the side air outlet through the second fan, which improves the heat exchange efficiency of the heat exchanger.

And when the air duct switching component is in the blocking state, the air duct switching component at least includes a part of a non-horizontal air duct plate section. In this way, the air supply effect of the air duct switching component sending the air of the first heat exchange part through the second fan and then from the side air outlet is improved.

[0061] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other.

[0062] The embodiments of the present disclosure provide a floor-mounted air conditioner indoor unit, which can also be called a vertical air conditioner indoor unit. As Figures 1 to 17 shown.

[0063] Optionally, the air conditioner indoor unit includes a housing 1, a first fan 21, a second fan 22, a heat exchanger 3, and an air duct switching component 4. The housing 1 is provided with an air inlet 101, and a front air outlet 102 is provided at the upper part of the housing 1, and a side air outlet 103 is provided at the side of the housing 1; the first fan 21 is communicated with the front air outlet 102 for forward air supply; the second fan 22 is communicated with the side air outlet 103 for side air supply; the heat exchanger 3 includes a first heat exchange part 31 and a second heat exchange part 32, and the air after heat exchange with the second heat exchange part 32 is sent out from the side air outlet 103 after passing through the second fan 22; the air duct switching component 4 is arranged between the first heat exchange part 31 and the first fan 21, and the air duct switching component 4 can be in a blocking state and a conducting state.

[0064] Wherein, when the air duct switching component 4 is in the conducting state, the air after heat exchange with the first heat exchange part 31 is sent out from the front air outlet 102 after passing through the first fan 21; when the air duct switching component 4 is in the blocking state, the air duct switching component 4 blocks the first heat exchange part 31 and the first fan 21, and the air after heat exchange with the first heat exchange part 31 is sent out from the side air outlet 103.

[0065] Optionally, the housing 1 includes a front housing part 11, a rear housing part, and a side housing part 12, and the front housing part 11 is disposed opposite to the rear housing part. Among them, the air inlet 101 is opened on the rear housing part, and an air inlet grille is provided at the air inlet 101; the front air outlet 102 is opened at the upper part of the front housing part 11, the side air outlet 103 includes a first side air outlet and a second side air outlet, the side air outlet 103 can be opened on the side housing part 12, and the side air outlet 103 can also be opened on the side of the front housing part 11.

[0066] Optionally, the front air outlet 102 is disposed above the side air outlet 103. Optionally, the front air outlet 102 can be circular, square, or other regular or irregular shapes; the side air outlet 103 is in a strip shape.

[0067] Optionally, the first blower 21 includes a centrifugal blower, an axial-flow blower, a cross-flow blower, etc.; the second blower 22 includes a cross-flow blower, a centrifugal blower, an axial-flow blower, etc. For example, the first blower 21 is a centrifugal blower, and the second blower 22 is a cross-flow blower, and the centrifugal blower is disposed above the cross-flow blower.

[0068] The indoor air conditioner provided by the embodiment of the present disclosure further includes an air duct switching component 4. The air duct switching component 4 is disposed between the first heat exchange part 31 of the heat exchanger 3 and the first blower 21. When only the side air outlet 103 needs to supply air, at this time, the first blower 21 for supplying air to the front air outlet 102 is in a closed state, and the second blower 22 for supplying air to the side air outlet 103 is in an open state. The air duct switching component 4 can be controlled to be in a blocking state that blocks the first heat exchange part 31 and the first blower 21, and the air duct switching component 4 forms an air duct between the first heat exchange part 31 and the second blower 22. At this time, the air-conditioning air with heat or cold generated by the first heat exchange part 31 can be sent out from the side air outlet 103 through the second blower 22.

[0069] It can be seen that for the indoor air conditioner provided by the embodiment of the present disclosure, when only the side air outlet 103 needs to supply air, with the first blower 21 turned off, the heat or cold generated by the first heat exchange part 31 can be sent out from the side air outlet 103 through the second blower 22, improving the heat exchange efficiency of the heat exchanger 3. At the same time, problems such as condensation caused by the inability of the first heat exchange part 31 to discharge cold air in time are avoided.

[0070] When the user needs to supply air from both the front air outlet 102 and the side air outlet 103 at the same time, the air duct switching component 4 can be controlled to be in a conducting state. At this time, the air duct between the first heat exchange part 31 of the heat exchanger 3 and the first blower 21 is conducted, and the air-conditioning air with heat or cold generated by the first heat exchange part 31 can be sent out from the front air outlet 102 after passing through the first blower 21.

[0071] Optionally, in the vertical direction, the second heat exchange part 32 of the heat exchanger 3 is disposed opposite to the second blower 22, that is, the second heat exchange part 32 and the second blower 22 are disposed at approximately the same height; optionally, the first blower 21 is disposed above the first heat exchange part 31. When the air duct switching component 4 is controlled to be in a conducting state, the air duct switching component 4 forms an air duct partition, and the air duct partition can be substantially in the shape of a horizontal flat plate. Moreover, the air duct switching component 4 separates the air-conditioning air generated by the first heat exchange part 31 and the second heat exchange part 32 of the heat exchanger 3, so that the air-conditioning air generated by the first heat exchange part 31 is sent out from the front air outlet 102 after passing through the first blower 21, and the air-conditioning air generated by the second heat exchange part 32 is sent out from the side air outlet 103 after passing through the second blower 22. As Figure 8 shown.

[0072] Optionally, the first heat exchange part 31 and the second heat exchange part 32 of the heat exchanger 3 are integrally formed, and the refrigerant pipelines between the first heat exchange part 31 and the second heat exchange part 32 are interconnected.

[0073] Optionally, the air duct switching component 4 includes a movable air duct part and a driving assembly. The driving assembly is used to drive the movable air duct part to rotate or move. The first fan 21 includes a first fan housing 211, and a first air wheel air inlet 212 is provided on the first fan housing 211. Among them, when the driving assembly drives the movable air duct part to rotate to the blocking state, the air duct switching component 4 blocks between the first heat exchange part 31 and the first air wheel air inlet 212.

[0074] Optionally, the first air wheel air inlet 212 is provided at the lower part of the first fan housing 211. When the first fan 21 is a centrifugal fan, the first air wheel air inlet 212 is a circular air inlet 101 provided at the lower part of the housing of the centrifugal fan, as Figure 4 shown.

[0075] Optionally, the driving assembly may include a driving motor, and the movable air duct part may be a plate-shaped air duct plate. The movable air duct part can rotate under the drive of the driving assembly so that the movable air duct part rotates to the blocking state or the conducting state.

[0076] When the movable air duct part rotates to the blocking state, the air duct switching component 4 blocks between the first heat exchange part 31 and the first air wheel air inlet 212, and at the same time forms an air duct between the first heat exchange part 31 and the second fan 22. In this way, when only the side air outlet 103 needs to supply air, the air-conditioning air generated by the first heat exchange part 31 can be sent out from the side air outlet 103 through the second fan 22. As Figure 5 shown.

[0077] Optionally, the movable air duct part includes a first rotating air duct plate 41. The first rotating air duct plate 41 includes a first rotating end 411 close to the first heat exchange part 31 and a second rotating end 412 far from the first heat exchange part 31; the heat exchanger 3 includes a first heat exchange end 311 close to the first fan 21. When the first rotating air duct plate 41 rotates to the conducting state, the distance between the first rotating end 411 and the first heat exchange end 311 is less than or equal to a first preset distance; and / or, the distance between the second rotating end 412 and the first fan housing 211 is less than or equal to a second preset distance. As Figure 12 and Figure 15 shown.

[0078] Optionally, the first rotating end 411 is the first rotation center 4101 of the first rotating air duct plate 41. Optionally, the first driving motor for driving the first rotating air duct plate 41 to rotate is drivingly installed with the first rotating end 411, and the second rotating end 412 rotates around the first rotating end 411 so that the first rotating air duct plate 41 can be in the conducting state or the blocking state.

[0079] Optionally, when the first rotating air duct plate 41 is in the conducting state, the first rotating air duct plate 41 is in a vertical shape, as shown in Figure 8 the figure; when the first rotating air duct plate 41 is in the blocking state, the first rotating air duct plate 41 is in an inclined shape, as shown in Figure 5 the figure. Optionally, the rotation angle formed when the first rotating air duct plate 41 rotates from the conducting state to the blocking state is greater than 95° and less than or equal to 150°.

[0080] When the first rotating air duct plate 41 rotates to the conducting state, the distance H1 between the first rotating end 411 of the first rotating air duct plate 41 and the first heat exchange end 311 is less than or equal to a first preset distance. Optionally, the first preset distance is greater than 0 and less than or equal to 10 mm. As shown in Figure 15 Figure A in the figure. In the embodiment of the present disclosure, the distance H1 between the first rotating end 411 and the first heat exchange end 311 should not be too large. In this way, when the air duct switching component 4 is in the conducting state, the first rotating air duct plate 41 can better guide the air-conditioning air generated by the first heat exchange part 31 to the first fan 21, improving the air outlet effect of the first fan 21. Optionally, the first rotating end 411 abuts against the first heat exchange part 31. As shown in Figure 12 Figure A in the figure.

[0081] When the first rotating air duct plate 41 rotates to the conducting state, the distance H2 between the second rotating end 412 of the first rotating air duct plate 41 and the first fan housing 211 is less than or equal to a second preset distance. Optionally, the second preset distance is greater than 0 and less than or equal to 10 mm. As shown in Figure 15 Figure A in the figure. In the embodiment of the present disclosure, the distance H2 between the second rotating end 412 and the first fan housing 211 should not be too large. In this way, when the air duct switching component 4 is in the conducting state, the first rotating air duct plate 41 can better guide the air-conditioning air generated by the first heat exchange part 31 to the first fan 21, improving the air outlet effect of the first fan 21. Optionally, the second rotating end 412 abuts against the first fan housing 211. As shown in Figure 12 Figure A in the figure.

[0082] Optionally, the first rotating air duct plate 41 is in a plate shape.

[0083] Optionally, the first rotating air duct plate 41 is in a flat plate shape, as shown in Figure 3As shown. Optionally, the first rotating air duct plate 41 is in the shape of a convex arc. It can be understood that when the first rotating air duct plate 41 is in the blocking state, the convex first rotating air duct plate 41 protrudes toward the first blower 21; it can also be understood that when the first rotating air duct plate 41 is in the conducting state, the convex first rotating air duct plate 41 protrudes toward the side away from the second blower 22. In this way, when the air duct switching component 4 forms a blocking state, the convex first rotating air duct plate 41 is conducive to smoothly sending the air out from the side air outlet 103 after passing through the second blower 22; in addition, when the air duct switching component 4 is in the conducting state, the convex first rotating air duct plate 41 will not block the air inlet 212 of the first impeller of the first blower 21, improving the air supply effect of the first blower 21.

[0084] Optionally, the movable air duct part further includes a second rotating air duct plate 42. Wherein, when the air duct switching component 4 is in the blocking state, the first rotating air duct plate 41 overlaps with the second rotating air duct plate 42, so that the first rotating air duct plate 41 and the second rotating air duct plate 42 jointly block the first heat exchange part 31 and the first blower 21.

[0085] When the air duct switching component 4 is in the blocking state, the first rotating air duct plate 41 is inclined, and the second rotating air duct plate 42 is also inclined. The first rotating air duct plate 41 overlaps with the second rotating air duct plate 42, so that the first rotating air duct plate 41 and the second rotating air duct plate 42 jointly block the first heat exchange part 31 and the first blower 21.

[0086] The first rotating air duct plate 41 overlaps with the second rotating air duct plate 42 to form an overlapping air duct, so that the air-conditioning air of the first heat exchange part 31 of the heat exchanger 3 is sent out from the side air outlet 103 after passing through the second blower 22.

[0087] Optionally, the second rotating air duct plate 42 includes a third rotating end 421 and a fourth rotating end 422, and the third rotating end 421 is the second rotating center 4201 of the second rotating air duct plate 42. When the air duct switching component 4 is in the blocking state, the second rotating end 412 of the first rotating air duct plate 41 overlaps with the second rotating air duct plate 42; or, the fourth rotating end 422 of the second rotating air duct plate 42 overlaps with the first rotating air duct plate 41. As Figure 7 shown.

[0088] Optionally, when the air duct switching component 4 is in the blocking state, the fourth rotating end 422 of the second rotating air duct plate 42 overlaps with the first rotating air duct plate 41. As Figures 3 to 7As shown. The overlapping position between the first rotating air duct plate 41 and the fourth rotating end 422 is located on the inner wall of the first rotating air duct plate 41, rather than at the second rotating end 412 of the first rotating air duct plate 41. In this way, when the air duct switching component 4 is in the blocking state, a partial remaining length exists on the first rotating air duct plate 41. This partial remaining length can be used to adjust the overlapping angle formed between the first rotating air duct plate 41 and the second rotating air duct plate 42.

[0089] Optionally, the overlapping angle A formed between the first rotating air duct plate 41 and the second rotating air duct plate 42 at the overlapping point is greater than 135° and less than 180°.

[0090] Optionally, the overlapping angle A formed between the first rotating air duct plate 41 and the second rotating air duct plate 42 can be adjusted according to the rotational speed of the second blower 22. For example, when the rotational speed of the second blower 22 is the first rotational speed, the first rotating air duct plate 41 and the second rotating air duct plate 42 form a first overlapping angle, and when the rotational speed of the second blower 22 is the second rotational speed, the first rotating air duct plate 41 and the second rotating air duct plate 42 form a second overlapping angle, where the first rotational speed is greater than the second rotational speed, and the first overlapping angle is less than the second overlapping angle.

[0091] When the second overlapping angle is less than the first overlapping angle, the volume of the air duct formed by the first rotating air duct plate 41 and the second rotating air duct plate 42 at the second overlapping angle is greater than the volume of the air duct formed at the first overlapping angle. In this way, when the second blower operates at the first rotational speed with a relatively high speed, the first rotating air duct plate 41 and the second rotating air duct plate 42 form an air duct with a larger volume, thereby improving the delivery effect of the air-conditioning air from the first heat exchange part 31 through the second blower 22 to the side air outlet 103.

[0092] Optionally, by adjusting the angle between the first rotating air duct plate 41 and the horizontal direction, and adjusting the angle between the second rotating air duct plate 42 and the horizontal direction, the first rotating air duct plate 41 and the second rotating air duct plate 42 can be made to form a first overlapping angle, or the first rotating air duct plate 41 and the second rotating air duct plate 42 can be made to form a second overlapping angle.

[0093] The third rotating end 421 of the second rotating air duct plate 42 and the first heat exchange end 311 form a first preset connection line. When the air duct switching component 4 is in the blocking state, the overlapping point formed between the first rotating air duct plate 41 and the second rotating air duct plate 42 is located above the first preset connection line, as Figure 7 shown as A in the figure. In this way, the volume of the overlapping air duct formed after the first rotating air duct plate 41 and the second rotating air duct plate 42 overlap is increased, and the air delivery effect of the air-conditioning air from the first heat exchange part 31 to the side air outlet 103 is improved.

[0094] Optionally, the vertical distance from the overlapping point formed by the first rotating air duct plate 41 and the second rotating air duct plate 42 to the first preset connection line is greater than 0 and less than or equal to 10 mm. In this way, when the air duct switching component 4 is in the blocking state, the air guiding effect of the first rotating air duct plate 41 and the second rotating air duct plate 42 is improved.

[0095] Optionally, the second rotating air duct plate 42 is in the shape of a flat plate, as Figure 3 shown. Optionally, the second rotating air duct plate 42 is in a concave arc shape. It can be understood that when the second rotating air duct plate 42 is in the blocking state or the conducting state, the concave second rotating air duct plate 42 protrudes toward the second blower 22. In this way, when the air duct switching component 4 forms a blocking state, the concave second rotating air duct plate 42 is conducive to forming an extension plate of the air duct of the first rotating air duct plate 41 and breaks the climbing effect of the wind, so that the wind smoothly passes through the second blower 22 and is sent out from the side air outlet 103; in addition, when the air duct switching component 4 is in the conducting state, the concave second rotating air duct plate 42 will not block the air-conditioning air of the first heat exchange part 31, improving the air supply effect of the first blower 21.

[0096] The width of the first rotating air duct plate 41 is K1, and the width of the heat exchanger 3 is K2. Optionally, K1≥K2. Optionally, the width of the first rotating air duct plate 41 is equal to the width of the second rotating air duct plate 42. Optionally, the width of the second rotating air duct plate 42 is greater than or equal to the diameter of the second blower 22. In this way, the air guiding effect of the air duct formed by the first rotating air duct plate 41 and the second rotating air duct plate 42 is improved. As Figure 17 shown.

[0097] Optionally, the air duct switching component 4 further includes a fixed air duct plate 43. The fixed air duct plate 43 includes a first fixed end 431 and a second fixed end 432. Among them, the first fixed end 431 is arranged at the third rotating end 421 of the second rotating air duct plate 42. When the air duct switching component 4 is in the blocking state, the first rotating air duct plate 41, the second rotating air duct plate 42 and the fixed air duct plate 43 jointly block the first heat exchange part 31 and the first blower 21; when the air duct switching component 4 is in the conducting state, the second rotating air duct plate 42 and the fixed air duct plate 43 form an air duct partition, and the air after heat exchange with the first heat exchange part 31 passes through the first blower 21 and is sent out from the front air outlet 102.

[0098] Optionally, the fixed air duct plate 43 is a fixed flat plate structure and does not need to rotate. The fixed air duct plate 43 can be used as an extended air duct plate of the second rotating air duct plate 42. Optionally, the fixed air duct plate 43 is arranged horizontally.

[0099] Optionally, the second fan 22 includes an upper end of the second fan close to the fixed air duct plate 43, wherein the distance between the fixed air duct plate 43 and the upper end of the second fan is H9, and H9 ≥ 10 mm. In this way, the noise of the fixed air duct plate 43 during the air guiding process is reduced. As Figure 12 shown.

[0100] Optionally, when the air duct switching component 4 is in the conducting state, the second rotating air duct plate 42 is in a flat plate shape and is horizontally arranged. The second rotating air duct plate 42 and the fixed air duct plate 43 form an air duct partition on the same horizontal line, as Figures 11 to 15 shown.

[0101] Optionally, when the air duct switching component 4 is in the blocking state, the air duct switching component 4 at least includes a partially non-horizontal air duct plate section 401. As Figure 7 shown.

[0102] When the air duct switching component 4 is in the blocking state, the air duct switching component 4 at least includes a partially non-horizontal air duct plate section. It can be understood that the non-horizontal air duct plate section 401 can be an inclined air duct plate, or composed of multiple inclined air duct plate sections. For example, the inclined first rotating air duct plate 41 and the second rotating air duct plate 42 are the non-horizontal air duct plate sections 401 of the air duct switching component 4, as Figure 7 shown in B.

[0103] Optionally, when the air duct switching component 4 is in the blocking state, the fixed air duct plate 43 forms a horizontal air duct plate section.

[0104] Optionally, the air duct switching component 4 includes a movable air duct part and a driving component. The movable air duct part includes a first rotating air duct plate 41 and a second rotating air duct plate 42; the driving component includes a first driving motor and a second driving motor, and the first driving motor is used to drive the first rotating air duct plate 41 to rotate, and the second driving motor is used to drive the second rotating air duct plate 42 to rotate. Wherein, when the air duct switching component 4 is in the blocking state, the first rotating air duct plate 41 overlaps with the second rotating air duct plate 42 to block the first heat exchange part 31 from the first fan 21.

[0105] In the embodiments of the present disclosure, the first driving motor and the second driving motor are respectively used to drive the first rotating air duct plate 41 and the second rotating air duct plate 42 to rotate. Optionally, the first driving motor can be installed on the inner wall of the housing 1, and the second driving motor can also be installed on the inner wall of the housing 1.

[0106] When the inner wall of the first rotating air duct plate 41 overlaps with the second rotating air duct plate 42, the second driving motor can be controlled to drive the second rotating air duct plate 42 to rotate to the overlapping position first, and then the first driving motor can be controlled to drive the first rotating air duct plate 41 to overlap with the second rotating air duct plate 42.

[0107] Optionally, in the extension direction of the heat exchanger 3, the length of the first rotating air duct plate 41 is the first length H3; the first fan 21 includes a first fan housing 211, the heat exchanger 3 includes a first heat exchange end 311 close to the first fan 21, and the distance between the first heat exchange end 311 and the first fan housing 211 is the first distance H4, where the first length H3 is less than or equal to the first distance H4.

[0108] As Figure 12 shown, the length of the first rotating air duct plate 41 is the first length H3, as Figure 15 shown, the distance between the first heat exchange end 311 and the bottom of the first fan housing 211 is the first distance H4. In the embodiment of the present disclosure, H3 ≤ H4. In this way, the distance between the first heat exchange end 311 and the first fan housing 211 can be large enough to enable the first rotating air duct plate 41 to rotate to a vertical state.

[0109] Optionally, the first rotating air duct plate 41 includes a first rotating end 411 and a second rotating end 412. The first rotating end 411 is the first rotation center 4101 of the first rotating air duct plate 41, where the first rotating end 411 is provided at the first heat exchange end 311. Optionally, H3 = H4, as Figure 13 shown in A.

[0110] Optionally, along the horizontal direction, the length of the second rotating air duct plate 42 is the second length H5; the second rotating air duct plate 42 includes a third rotating end 421 and a fourth rotating end 422. The third rotating end 421 is the second rotation center 4201 of the second rotating air duct plate 42, and the distance between the third rotating end 421 and the heat exchanger 3 is the second distance H6, where the second length H5 is less than or equal to the second distance H6.

[0111] The length of the second rotating air duct plate 42 is the second length H5, and the distance between the third rotating end 421 and the heat exchanger 3 is the second distance H6. In the embodiment of the present disclosure, H5 ≤ H6. In this way, the distance formed between the third rotating end 421 and the heat exchanger 3 can be large enough to enable the second rotating air duct plate 42 to rotate to a horizontal state. As Figure 13 shown.

[0112] Optionally, the sum of the first length H3 of the first rotating air duct plate 41 and the second length H5 of the second rotating air duct plate 42 is greater than the connecting line distance between the third rotating end 421 and the first heat exchange end 311. The connecting line distance is the length of the first preset connecting line located between the third rotating end 421 and the first heat exchange end 311.

[0113] Optionally, when the air duct switching component 4 is in the blocking state, the first driving motor drives the first rotating air duct plate 41 to rotate to an inclined state, the second driving motor drives the second rotating air duct plate 42 to rotate to an inclined state, and the first rotating air duct plate 41 and the second rotating air duct plate 42 are overlapped with each other to form a non-horizontal air duct plate section 401.

[0114] Optionally, in the horizontal direction, the length of the fixed air duct plate 43 is the third length H7; the housing 1 includes a front housing portion 11 provided with a front air outlet 102, and the distance between the heat exchanger 3 and the front housing portion 11 is the third distance H8, wherein the sum of the second length H5 and the third length H7 is less than or equal to the third distance H8.

[0115] In the embodiment of the present disclosure, the sum of the second length H5 and the third length H7 is less than or equal to the third distance H8, so that when the air duct switching component 4 is in the conducting state, the fixed air duct plate 43 and the second rotating air duct plate 42 can both be in a horizontal plate state and are on the same horizontal line, improving the air guiding stability when the air duct switching component 4 is in the conducting state.

[0116] Optionally, the third length H7 is greater than or equal to the second length H5; and / or, the second length H5 is greater than or equal to the first length H3.

[0117] The first length H3 of the first rotating air duct plate 41 can be set according to the first distance H4 between the first heat exchange end 311 of the heat exchanger 3 and the bottom of the first fan housing 211; or, the second length H5 of the second rotating air duct plate 42 and the third length H7 of the fixed air duct plate 43 can be set according to the third distance H8 between the heat exchanger 3 and the front housing portion 11.

[0118] The air conditioner indoor unit provided by the embodiment of the present disclosure is provided with a front air outlet 102 and a side air outlet 103 located below the front air outlet 102 at the same time. Optionally, the front air outlet 102 can be applied to operation modes such as long-distance air supply, rapid cooling or rapid heating; when the air outlet temperature of the air conditioner indoor unit is not much different from the set temperature, only the side air outlet 103 can be used for air supply.

[0119] When only the side air outlet 103 is required for air supply, the air duct switching component 4 can be controlled to rotate to the blocking state, so that the air conditioner air of the first heat exchange portion 31 of the heat exchanger 3 is sent out from the side air outlet 103 after passing through the second fan 22, improving the heat exchange efficiency of the heat exchanger 3, and at the same time, avoiding problems such as condensation caused by cold accumulation of the first heat exchange portion 31.

[0120] The embodiment of the present disclosure also provides an air conditioner, including the air conditioner indoor unit as described above.

[0121] The embodiment of the present disclosure provides a method for controlling an air conditioner indoor unit, including:

[0122] S81. When the air conditioner is started, the air conditioner obtains the set temperature of the air conditioner and the temperature of the room where the air conditioner is located.

[0123] S82. The air conditioner controls the air duct switching component according to the difference between the set temperature of the air conditioner and the temperature of the room where the air conditioner is located, so that the air duct switching component is in a blocked state or a conducting state.

[0124] Wherein, when the air duct switching component is in the conducting state, the air after heat exchange with the first heat exchange part is sent out from the front air outlet after passing through the first fan; when the air duct switching component is in the blocked state, the air duct switching component blocks the first heat exchange part and the first fan, and the air after heat exchange with the first heat exchange part is sent out from the side air outlet.

[0125] In this solution, when the air conditioner is started, the air conditioner can obtain the set temperature of the air conditioner and the temperature of the room where the air conditioner is located. Specifically, the set temperature is usually input by the user through a remote control or the control panel of the air conditioner. There are various designs for obtaining the room temperature. In one example, to ensure the accuracy and reliability of the temperature information, the air conditioner can obtain the room temperature through a built-in temperature sensor. The sensor is installed at the air inlet of the air conditioner and can monitor the temperature of the air entering the air conditioner in real time, thereby indirectly reflecting the temperature situation in the room. In another example, the air conditioner can also be equipped with an external temperature sensor, and the external temperature sensor is connected to the air conditioner wirelessly or by wire. The external sensor can be placed at different positions in the room to more accurately measure the actual temperature in the room and avoid affecting the measurement result due to local temperature changes near the air conditioner. In an optimized solution, in a smart home environment, the air conditioner can directly obtain the room temperature information from other smart devices through integration with the smart home system. These smart devices are distributed in various corners of the room and can provide more comprehensive and accurate temperature data, providing a more reliable basis for the intelligent control of the air conditioner. Optionally, the user can also manually input the room temperature according to his actual feeling. Although this method is not as accurate as automatic detection, it can be used as a supplementary means when there is no sensor or the sensor fails to ensure that the air conditioner can still operate according to the user's subjective needs.

[0126] Further, after the air conditioner obtains the set temperature of the air conditioner and the temperature of the room where the air conditioner is located, the air duct switching component is controlled according to the difference between the set temperature of the air conditioner and the temperature of the room where the air conditioner is located, so that the air duct switching component is in a blocked state or a conducting state. In one example, when the difference between the set temperature of the air conditioner and the room temperature is large, it indicates that the air conditioner needs to quickly adjust the room temperature to reach the set value. At this time, the air duct switching component is controlled to be in a conducting state, so that the air after heat exchange with the first heat exchange part is sent out from the front air outlet after passing through the first fan. The front air outlet usually has a longer air supply distance, which can quickly send cold air or warm air to all corners of the room and accelerate the adjustment of the room temperature. When the difference between the set temperature and the room temperature is small, it indicates that the room temperature is already close to the set value. At this time, the air duct switching component is controlled to be in a blocked state, blocking the first heat exchange part and the first fan, so that the air after heat exchange with the first heat exchange part is sent out from the side air outlet, in order to provide a more comfortable air supply experience for users and reduce the discomfort caused by direct air blowing at the same time.

[0127] With this solution, by using the air duct switching component, according to the difference between the set temperature and the room temperature, the air duct state is flexibly switched to realize air supply from the front air outlet or the side air outlet. This not only enriches the air supply dimension, expands the space coverage range, but also can adjust the air supply direction according to needs to avoid direct air blowing at the user. Thus, while effectively expanding the air supply dimension, it significantly reduces the discomfort caused by direct air blowing, meets the personalized needs of users for multi-dimensional air supply, and improves the use experience and space adjustment efficiency of the air conditioner.

[0128] Optionally, in S82, the air conditioner controls the air duct switching component according to the difference between the set temperature of the air conditioner and the temperature of the room where the air conditioner is located, so that the air duct switching component is in a blocked state or a conducting state, including:

[0129] When the difference between the set temperature of the air conditioner and the temperature of the room where the air conditioner is located is greater than the temperature difference threshold, the air conditioner controls the air duct switching component to switch to the conducting state.

[0130] When the difference between the set temperature of the air conditioner and the temperature of the room where the air conditioner is located is less than or equal to the temperature difference threshold, the air conditioner controls the air duct switching component to switch to the blocked state.

[0131] In this solution, during the operation of the air conditioner, the set temperature of the air conditioner and the temperature of the room where it is located can be monitored in real time, and the difference between the two can be calculated. It should be noted that if the difference is less than zero, the absolute value of the difference needs to be determined and compared with the temperature difference threshold. Specifically, when the difference is greater than the temperature difference threshold, the air conditioner controls the air duct switching component to switch to the conducting state. At this time, the air duct between the first heat exchange part and the first fan is unobstructed, and the air after heat exchange is sent out from the front air outlet through the first fan. At the same time, the second fan also keeps running, so that the air after heat exchange in the second heat exchange part is sent out from the side air outlet, realizing simultaneous air supply from the front air outlet and the side air outlet. This way of simultaneous air supply can quickly adjust the room temperature when the room temperature differs greatly from the set temperature, improving the cooling or heating efficiency of the air conditioner. In addition, when the difference between the set temperature of the air conditioner and the room temperature is less than or equal to the temperature difference threshold, the air conditioner controls the air duct switching component to switch to the blocking state. At this time, the air duct switching component blocks the first heat exchange part and the first fan, so that the air after heat exchange in the first heat exchange part cannot enter the first fan but is directly sent out through the side air outlet. This way of only supplying air through the side air outlet is suitable when the room temperature is close to the set temperature, which can provide a softer and more uniform air supply experience for users, reduce the discomfort caused by direct air blowing, and maintain the stability of the room temperature.

[0132] With this solution, not only the performance of the air conditioner is optimized, but also the user experience is improved, enabling it to better adapt to different usage scenarios and requirements.

[0133] In this solution, the temperature difference threshold can be set in advance. As an example, the temperature difference threshold can be 2°C.

[0134] Optionally, the temperature difference threshold is dynamically adjusted according to the following information:

[0135] The current time information; or,

[0136] The current outdoor environmental parameter information; or,

[0137] The current indoor environmental parameter information; or,

[0138] The current season information; or,

[0139] The current geographical location information.

[0140] In one example, the temperature difference threshold can be adjusted according to the current time information. For example, at night or in the sleep mode set by the user, the temperature difference threshold can be appropriately reduced so that the air conditioner can switch to a softer air supply mode at a smaller temperature difference, reducing the interference of the air supply at night to the user and providing a more comfortable sleep environment. During the day or when the user is more active, the temperature difference threshold can be appropriately increased so that the air conditioner can more actively adjust the indoor temperature to meet the higher temperature requirements of the user during activities.

[0141] In one example, the temperature difference threshold can also be adjusted according to the current outdoor environmental parameter information. For example, when the outdoor temperature is relatively high or low, the temperature difference threshold can be appropriately increased so that the air conditioner can more actively adjust the indoor temperature to cope with the large indoor-outdoor temperature difference. In addition, if the outdoor humidity is relatively high, the temperature difference threshold can also be appropriately adjusted to ensure that the air conditioner reaches the best balance between dehumidification and refrigeration or heating, improving the comfort of the user.

[0142] In one example, the temperature difference threshold can be dynamically adjusted according to the current indoor environmental parameter information. For example, if the indoor humidity is relatively high, the temperature difference threshold can be appropriately reduced so that the air conditioner can switch to the ventilation mode more frequently, reducing the indoor humidity and improving the indoor air quality. If the indoor air quality is poor, the temperature difference threshold can also be appropriately adjusted so that the air conditioner can more effectively circulate and purify the air.

[0143] In one example, the temperature difference threshold can also be adjusted according to the current season information. In summer or winter, due to the large indoor-outdoor temperature difference, the temperature difference threshold can be appropriately increased so that the air conditioner can more effectively adjust the indoor temperature. In spring and autumn, the temperature difference threshold can be appropriately reduced to achieve a more energy-efficient operation mode and reduce unnecessary energy consumption.

[0144] In one example, the temperature difference threshold can be adjusted according to the current geographical location information. For example, in locations close to windows or doors, since these areas are more easily affected by the external temperature, the temperature difference threshold can be appropriately increased to ensure that the temperature in these areas can also be effectively adjusted. In addition, under the climate conditions of different geographical locations, the temperature difference threshold can also be optimized and adjusted according to the local climate characteristics to adapt to different environmental requirements.

[0145] With this solution, by introducing a mechanism for dynamically adjusting the temperature difference threshold, the air conditioner can flexibly adjust the air supply mode according to various information such as the current time, indoor and outdoor environmental parameters, season, and geographical location, achieving more accurate and intelligent temperature regulation and air supply control. This intelligent control method can not only meet the personalized needs of users in different scenarios but also effectively reduce energy consumption, providing a more comfortable and energy-efficient indoor environment for users.

[0146] Optionally, the air duct switching component includes a movable air duct portion, and the movable air duct portion includes a first rotating air duct plate and a second rotating air duct plate. When the air duct switching component is in the blocking state, the first rotating air duct plate and the second rotating air duct plate overlap each other, so that the first rotating air duct plate and the second rotating air duct plate jointly block the first heat exchange portion and the first fan. The method further includes:

[0147] S91, the air conditioner obtains the rotation speed of the second fan.

[0148] S92, the air conditioner adjusts the overlapping angle between the first rotating air duct plate and the second rotating air duct plate according to the rotation speed of the second fan.

[0149] In this solution, when the rotation speed of the second fan is the first rotation speed, the first rotating air duct plate and the second rotating air duct plate form a first overlapping angle. When the rotation speed of the second fan is the second rotation speed, the first rotating air duct plate and the second rotating air duct plate form a second overlapping angle. Wherein, the first rotation speed is greater than the second rotation speed, and the first overlapping angle is less than the second overlapping angle.

[0150] Specifically, when the second overlapping angle is less than the first overlapping angle, the volume of the air duct formed by the first rotating air duct plate and the second rotating air duct plate at the second overlapping angle is greater than the volume of the air duct formed at the first overlapping angle. In this way, when the second fan operates at the first rotation speed with a relatively high rotation speed, the first rotating air duct plate and the second rotating air duct plate constitute an air duct with a larger volume, thereby improving the delivery effect of the air-conditioning air of the first heat exchange portion from the side air outlet after passing through the second fan.

[0151] Optionally, by adjusting the angle between the first rotating air duct plate and the horizontal direction, and adjusting the angle between the second rotating air duct plate and the horizontal direction, the first rotating air duct plate and the second rotating air duct plate can form a first overlapping angle, or the first rotating air duct plate and the second rotating air duct plate can form a second overlapping angle.

[0152] Optionally, the air duct switching component includes a movable air duct portion, and the movable air duct portion includes a first rotating air duct plate and a second rotating air duct plate. When the air duct switching component is in the blocking state, the first rotating air duct plate and the second rotating air duct plate overlap each other, so that the first rotating air duct plate and the second rotating air duct plate jointly block the first heat exchange portion and the first fan. The method further includes:

[0153] The air conditioner determines the user's air supply intention, and the air supply intention includes micro-cooling air supply and strong-cooling air supply.

[0154] When the user's air supply intention is micro-cooling air supply, the air conditioner increases the overlapping angle between the first rotating air duct plate and the second rotating air duct plate.

[0155] When the user's air supply intention is strong cold air supply, the air conditioner reduces the overlapping angle between the first rotating air duct plate and the second rotating air duct plate.

[0156] In this solution, the movable air duct part of the air duct switching component includes a first rotating air duct plate and a second rotating air duct plate. When the air duct switching component is in the blocking state, the first rotating air duct plate overlaps with the second rotating air duct plate, jointly blocking the first heat exchange part and the first fan, so that the air after heat exchange through the first heat exchange part can only be sent out from the side air outlet. This design not only optimizes the air supply direction but also improves the heat exchange efficiency. To further meet the personalized needs of users, this method also includes the step of adjusting the overlapping angle between the first rotating air duct plate and the second rotating air duct plate according to the user's air supply intention.

[0157] When the air conditioner determines the user's air supply intention, it will make corresponding air duct adjustments according to the mode selected by the user. If the user selects the mild cold air supply mode, the air conditioner will increase the overlapping angle between the first rotating air duct plate and the second rotating air duct plate through the internal drive mechanism. This adjustment makes the air duct volume formed between the first rotating air duct plate and the second rotating air duct plate smaller. Understandably, due to the reduction of the air duct volume, the flow path of the air in the air duct becomes narrower, and the air speed and air volume will both decrease accordingly. After the air cooled by the first heat exchange part passes through the second fan and is sent out from the side air outlet, the decrease in the air volume and air speed makes the intensity of the blown cold air weaken, thus achieving the mild wind effect. This mild wind effect can provide users with a more gentle and comfortable cold air experience and is suitable for use in scenarios where the temperature is appropriate but a slight temperature reduction is needed.

[0158] On the contrary, when the user selects the strong cold air supply mode, the air conditioner will reduce the overlapping angle between the first rotating air duct plate and the second rotating air duct plate. At this time, the air duct volume formed between the first rotating air duct plate and the second rotating air duct plate increases. The increase in the air duct volume makes the flow path of the air in the air duct wider, and the air speed and air volume will both increase accordingly. After the air cooled by the first heat exchange part passes through the second fan and is sent out from the side air outlet, the increase in the air volume and air speed makes the intensity of the blown cold air increase, thus achieving the strong cold effect. This strong cold effect can quickly reduce the indoor temperature and is suitable for use in hot weather or scenarios where rapid temperature reduction is required.

[0159] In the process of implementing these two air supply modes, the control system of the air conditioner will accurately control the rotation angle of the air duct plate according to the user's selection. The control system will monitor the angle change of the air duct plate in real time and make fine adjustments based on the feedback information to ensure that the air duct adjustment meets the user's air supply intention. At the same time, the control system will also coordinate and adjust the speed of the blower according to the angle change of the air duct plate to further optimize the air supply effect. For example, in the slightly cold air supply mode, the blower speed may be appropriately reduced to further reduce the air volume and wind speed; while in the strong cold air supply mode, the blower speed may be appropriately increased to enhance the air supply effect.

[0160] In addition, the air conditioner can also allow the user to intuitively select the slightly cold air supply or strong cold air supply mode through the user interface and display the current air supply status in real time. If the user is not satisfied with the air supply effect, they can make adjustments through the interface, and the control system will re-adjust the angle of the air duct plate and the speed of the blower according to the user's feedback to ensure that the user obtains a satisfactory air supply experience.

[0161] Through this design, the air conditioner can flexibly adjust the overlapping angle of the air duct plate according to the user's air supply intention, so as to realize the switching between slightly cold air supply and strong cold air supply. This solution can not only accurately meet the user's needs for different air supply intensities, but also improve the operating efficiency and comfort of the air conditioner. In the slightly cold air supply mode, by reducing the air duct volume, the air volume and wind speed are reduced, avoiding the discomfort caused by excessive cooling; in the strong cold air supply mode, by increasing the air duct volume, the air volume and wind speed are increased, quickly reducing the indoor temperature and enhancing the refrigeration effect. At the same time, this adjustment method can also reduce the energy consumption of the air conditioning system, because the optimization of the air duct can reduce the operating load of the blower, thus achieving the effect of energy saving.

[0162] In an optimized solution, the air conditioner can predict the user's preferences and habits by recording the user's historical usage data. For example, the system can record the air supply mode selected by the user at different time periods (such as day, night, weekend, etc.) and the corresponding overlapping angle of the air duct plate. By analyzing this historical data, the air conditioner can automatically adjust the overlapping angle of the air duct plate to meet the user's regular needs.

[0163] In an optimized solution, the air conditioner can also use a preset model to dynamically adjust the overlapping angle of the air duct plate. These models can predict the optimal air supply mode based on various factors, such as indoor and outdoor temperature, humidity, season, geographical location, etc. For example, during high-temperature periods in summer, the model may suggest reducing the overlapping angle to provide strong cold air supply; while in spring and autumn or when the indoor temperature is relatively low, the model may suggest increasing the overlapping angle to provide mild cold air supply. In addition, the model can also combine the indoor humidity situation. If the indoor humidity is high, it may suggest appropriately reducing the overlapping angle to enhance the dehumidification effect. In this way, the air conditioner can automatically adjust the overlapping angle of the air duct plate according to the changes in environmental conditions, so as to provide the best air supply effect in different usage scenarios.

[0164] Optionally, the method further includes:

[0165] The air conditioner determines the user's air supply intention, and the air supply intention includes normal-temperature air supply, mild cold air supply, and strong cold air supply.

[0166] When the user's air supply intention is normal-temperature air supply, the air conditioner controls the air duct switching component to be in a blocked state and starts the first fan to provide gentle normal-temperature air for the user through the front air outlet.

[0167] When the user's air supply intention is mild cold air supply, the air conditioner controls the air duct switching component to be in a blocked state and starts the first fan and the second fan, so that the front air outlet outputs gentle normal-temperature air and the side air outlet outputs cold air, so as to provide mild air for the user through the mixing of the two.

[0168] When the user's air supply intention is strong cold air supply, the air conditioner controls the air duct switching component to switch to a conducting state and starts the first fan and the second fan, so that the front air outlet and the side air outlet output cold air synchronously to achieve rapid cooling.

[0169] In this solution, the user's air supply intention is subdivided into three modes: normal-temperature air supply, mild cold air supply, and strong cold air supply. The air conditioner can flexibly adjust the state of the air duct switching component and the operation mode of the fan according to different air supply intentions to meet the personalized needs of users in different scenarios. Specifically, when the user's air supply intention is normal-temperature air supply, the air conditioner controls the air duct switching component to be in a blocked state. At this time, the air duct between the first heat exchange part and the first fan is blocked, indicating that the air after heat exchange by the first heat exchange part cannot directly enter the first fan. Therefore, the air conveyed by the first fan will not pass through the first heat exchange part for further temperature adjustment, so as to provide gentle air close to normal temperature for the user.

[0170] When the user's air supply intention is to supply slightly cold air, the air conditioner also controls the air duct switching component to be in a blocked state. However, at this time, the first fan and the second fan will be started simultaneously. The first fan outputs normal-temperature gentle air from the front air outlet, while the second fan outputs cold air from the side air outlet. Through the mixing of the air from the front air outlet and the side air outlet, a slightly cold air supply effect is provided for the user. This mode is suitable for use in scenarios where the user needs a slight temperature drop but does not want to be blown by strong cold air, such as when the indoor temperature is relatively high but the user is sensitive to cold air.

[0171] When the user's air supply intention is to supply strong cold air, the air conditioner controls the air duct switching component to switch to a conducting state. At this time, the air duct between the first heat exchange part and the first fan is unobstructed, and the first fan and the second fan operate simultaneously, so that the front air outlet and the side air outlet output cold air synchronously. This mode can quickly reduce the room temperature and is suitable for use in hot weather or when the user needs rapid refrigeration, such as during high-temperature periods in summer or when the user first enters the room and needs to quickly cool down.

[0172] With this solution, the user can choose different air supply modes according to their comfort preferences, and the air conditioner realizes the corresponding air supply effect through intelligent control. This intelligent control method not only improves the user's experience but also further enhances the energy efficiency and heat exchange efficiency of the air conditioner, enabling it to perform well in various complex usage environments. By dynamically adjusting the air supply mode, the air conditioner can more accurately control the air supply volume and air speed, so that while quickly refrigerating or heating, it can also provide a more comfortable and uniform air supply experience for the user, significantly improving the overall performance of the air conditioner and the user's satisfaction.

[0173] Optionally, the air conditioner determines the user's air supply intention, including:

[0174] The air conditioner obtains the key value information, environmental parameter data, human body state data, and historical habit data input by the user.

[0175] The air conditioner determines the user's air supply intention based on the key value information, environmental parameter data, human body state data, and historical habit data input by the user.

[0176] In this solution, the air conditioner determines the user's air supply intention by comprehensively analyzing the key value information, environmental parameter data, human body state data, and historical habit data input by the user. Specifically, the air conditioner can obtain the key value information input by the user through the remote control or the air conditioner panel, and the key value information can include the set temperature, wind speed gear, air supply mode, etc. For example, if the user sets the temperature to 24°C, selects "low" for the wind speed, and selects the "cooling" mode, the air conditioner will initially judge that the user may need slightly cold air supply. At the same time, the air conditioner obtains environmental parameter data through built-in or external sensors, such as indoor temperature, humidity, and air quality. If the indoor temperature is 28°C and the humidity is 60%, the air conditioner will further judge that the user may need a stronger cooling effect by combining these data. In addition, the air conditioner can also obtain human body state data through smart wearable devices or body sensors, such as the user's body temperature and activity state. If the user's body temperature is 37°C and is in an active state, the air conditioner may adjust the judgment and consider that the user needs stronger cold air to cool down. Finally, the air conditioner will refer to the historical habit data to understand the user's preferences under similar conditions. For example, if the historical data shows that the user usually selects slightly cold air supply at night, the air conditioner will automatically adjust to this mode at night. By integrating these data, the air conditioner can more accurately determine the user's air supply intention and achieve personalized and intelligent air supply control.

[0177] As an example, the air conditioner can determine the user's air supply intention through the weighted analysis method. Specifically, the air conditioner assigns different weights to the key value information, environmental parameter data, human body state data, and historical habit data input by the user. For example, the weight of the key value information is relatively high because this is the way for the user to directly express their needs; the weight of the environmental parameter data is the second, which is used to correct and supplement the key value information; the weight of the human body state data is the third, which is used to further refine the needs; the weight of the historical habit data is the lowest, but it can be used as a long-term reference. Through weighted calculation, a comprehensive judgment result is obtained to determine the air supply intention.

[0178] As an example, the air conditioner can determine the user's air supply intention through the hierarchical decision-making method. Specifically, the air conditioner makes a preliminary judgment based on the key value information input by the user to determine a basic air supply mode. Then, it adjusts the preliminary judgment by combining the environmental parameter data. For example, it fine-tunes the air supply intensity or temperature setting according to the indoor temperature and humidity. Next, it further optimizes the air supply mode by referring to the human body state data, such as adjusting the wind speed or direction according to the user's body temperature and activity state. Finally, it fine-tunes the final result by combining the historical habit data to ensure that the air supply mode conforms to the user's long-term preferences.

[0179] As an example, the air conditioner can determine the user's air supply intention through data fusion and machine learning algorithms. Specifically, the air conditioner fuses the key value information input by the user, environmental parameter data, human body state data, and historical habit data to form a comprehensive data set. Through machine learning algorithms (such as decision trees, neural networks, etc.), these data are trained and analyzed to establish a prediction model. When new data is input, the model can automatically identify and predict the user's air supply intention, thereby realizing intelligent air supply control.

[0180] With this solution, by comprehensively analyzing the key value information input by the user, environmental parameter data, human body state data, and historical habit data to determine the air supply intention, more intelligent and personalized air supply control can be achieved. This multi-dimensional data analysis method not only improves the intelligence level of the air conditioner but also significantly enhances the user experience. The air conditioner can automatically adjust the air supply mode according to the actual needs of the user and environmental conditions, providing the most comfortable and energy-saving air supply effect for the user. This intelligent control method reduces the frequency of manual operation by the user, improves the convenience of use, and also provides data support for the efficient operation of the air conditioner.

[0181] An embodiment of the present disclosure provides a device for controlling an air conditioner indoor unit, including an acquisition module and a control module. The acquisition module is configured to obtain the set temperature of the air conditioner and the temperature of the room where the air conditioner is located when the air conditioner is started; the control module is configured to control the air duct switching component according to the difference between the set temperature of the air conditioner and the temperature of the room where the air conditioner is located, so that the air duct switching component is in a blocked state or a conducting state. Wherein, when the air duct switching component is in the conducting state, the air after heat exchange with the first heat exchange part is sent out from the front air outlet after passing through the first fan; when the air duct switching component is in the blocked state, the air duct switching component blocks the first heat exchange part and the first fan, and the air after heat exchange with the first heat exchange part is sent out from the side air outlet.

[0182] By using the device for controlling an air conditioner indoor unit provided by the embodiment of the present disclosure, the air duct state can be flexibly switched according to the difference between the set temperature and the room temperature by using the air duct switching component to realize air supply from the front air outlet or the side air outlet. This not only enriches the air supply dimension and expands the space coverage range but also can adjust the air supply direction according to the demand to avoid the air flow directly blowing on the user. Thus, while effectively expanding the air supply dimension, it significantly reduces the discomfort caused by the direct air flow, meets the user's personalized needs for multi-dimensional air supply, and improves the user experience and space adjustment efficiency of the air conditioner.
