That is, the air blown out by the first blower is selectively guided at the upstream of the air outlet in the entire air outlet path. This direction adjusting method greatly reduces the loss of the air volume.

[0078] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0079] An embodiment of the present disclosure provides a cabinet-type air conditioner indoor unit, which may also be referred to as a floor-standing air conditioner indoor unit or a vertical air conditioner indoor unit, etc.

[0080] Optionally, the air conditioner indoor unit includes a housing 1, a fan assembly, a wind guide ring assembly 5, and a wind blocking and direction adjusting assembly 6. The housing 1 is provided with a front air outlet 102 for blowing air forward. The fan assembly includes a first fan 21 communicated with the front air outlet 102. The first fan 21 includes a first fan housing 211, and a first wind wheel air outlet 213 is opened on the first fan housing 211. The wind guide ring assembly 5 is disposed in a first air duct between the first wind wheel air outlet 213 and the front air outlet 102. The wind blocking and direction adjusting assembly 6 is used for blocking a part of the wind guide ring assembly 5 to adjust the air outlet direction of the front air outlet 102.

[0081] Optionally, the front air outlet 102 provided on the housing 1 may be a circular air outlet or a square air outlet. Optionally, the front air outlet 102 is disposed on the upper part of the housing 1.

[0082] Optionally, the wind guide ring assembly 5 includes at least two wind guide rings with a through middle. The plurality of wind guide rings are arranged in sequence in the front-rear direction or the horizontal direction to form a through air duct. A jet port is formed between two adjacent wind guide rings. The jet port guides the air from the first wind wheel air outlet 213 of the first fan 21 to the front air outlet 102 to blow air forward.

[0083] Optionally, the first fan 21 is a centrifugal fan and is disposed at the lower part of the wind guide ring assembly 5. Optionally, the first wind wheel air outlet 213 is perpendicular to the wind guide ring assembly 5. The wind guide ring has an arc-shaped wind guide surface. After the air blown out from the first wind wheel air outlet 213 is redirected by the arc-shaped wind guide surface of the wind guide ring, it is sent out from the front air outlet 102.

[0084] The air conditioner indoor unit provided by the embodiment of the present disclosure is further provided with a wind blocking and direction adjusting assembly 6. The wind blocking and direction adjusting assembly 6 is used for blocking a part of the wind guide ring assembly 5, so that the air blown out from the first wind wheel air outlet 213 is blown out through the unblocked part of the wind guide ring assembly 5, thereby adjusting the air outlet direction of the front air outlet 102.

[0085] Optionally, the wind blocking and direction adjusting assembly 6 blocks a circumferential part of the wind guide ring assembly 5. For example, the wind blocking and direction adjusting assembly 6 blocks the lower part of the circumferential direction of the wind guide ring assembly 5. In this way, the air blown out from the first wind wheel air outlet 213 is blown out through the upper part of the circumferential direction of the wind guide ring assembly 5, so that the direction of the air blown out from the front air outlet 102 is inclined downward, as Figure 5 shown. Or, the wind blocking and direction adjusting assembly 6 blocks the upper part of the circumferential direction of the wind guide ring assembly 5. In this way, the air blown out from the first wind wheel air outlet 213 is blown out through the lower part of the circumferential direction of the wind guide ring assembly 5, so that the direction of the air blown out from the front air outlet 102 is inclined upward, as Figure 6As shown

[0086] It can be understood that the wind deflector and direction adjustment component 6 can also block the circumferential side parts of the air guide ring component 5. For example, it can block the left side or the right side of the air guide ring component 5, so that the direction of the air blown out from the front air outlet 102 is inclined to the right or to the left.

[0087] It can be seen that the air conditioner indoor unit provided with the wind deflector and direction adjustment component 6 in the embodiments of the present disclosure can adjust the air outlet direction of the front air outlet 102 in multiple directions such as up, down, left, and right, improving the diversity of the air outlet direction of the front air outlet 102. Optionally, the wind deflector and direction adjustment component 6 can rotate circumferentially around the air guide ring component 5 to block different positions in the circumferential direction of the air guide ring component 5 according to the user's air outlet requirements, thereby adjusting the air outlet direction of the front air outlet 102.

[0088] Moreover, the wind deflector and direction adjustment component 6 is arranged at the air guide ring component 5. In this way, the air blown out from the first air wheel air outlet 213 can be selectively led out through the unblocked part of the air guide ring component 5, and problems such as air stagnation and large air volume loss will not occur.

[0089] Optionally, the air guide ring component 5 includes an outer air guide 51 close to the first air wheel air outlet 213 and an inner air guide 52 close to the front air outlet 102, wherein the wind deflector and direction adjustment component 6 is arranged on the outer air guide 51 or the inner air guide 52.

[0090] The outer air guide 51 can be understood as the outer ring of the air guide ring in the air guide ring component 5, and the inner air guide 52 can be understood as the inner ring of the air guide ring in the air guide ring component 5, as Figure 7 shown. In the embodiments of the present disclosure, the wind deflector and direction adjustment component 6 can be arranged on the inner air guide 52 or the outer air guide 51 of the air guide ring component 5 to block the air from the inner air guide 52 or the outer air guide 51. As Figure 7 shown, the wind deflector and direction adjustment component 6 is arranged on the outer air guide 51.

[0091] Optionally, the wind deflector and direction adjustment component 6 abuts against the outer air guide 51 or the inner air guide 52 of the air guide ring component 5.

[0092] When the wind deflector and direction adjustment component 6 is arranged on the outer air guide 51, the wind deflector and direction adjustment component 6 abuts against the outer air guide 51. It can also be understood that there is no air passing gap between the wind deflector and direction adjustment component 6 and the outer air guide 51; when the wind deflector and direction adjustment component 6 is arranged on the inner air guide 52, the wind deflector and direction adjustment component 6 abuts against the inner air guide 52. It can also be understood that there is no air passing gap between the wind deflector and direction adjustment component 6 and the inner air guide 52. In this way, the blocking effect of the wind deflector and direction adjustment component 6 on the blocked part of the air guide ring component 5 is improved.

[0093] Optionally, the air guide ring assembly 5 includes an air guiding part and a shielding part that forms an occlusion with the wind shielding and direction adjusting assembly 6. The wind blown out from the first wind wheel air outlet 213 is adjusted in direction by the air guiding part of the air guide ring assembly 5 and then sent out from the front air outlet 102. Among them, the length formed by the shielding part is the shielding length L0, the circumferential length of the air guide ring assembly 5 is L, and 0.25L ≤ L0 ≤ 0.8L.

[0094] The air guide ring in the air guide ring assembly 5 is circular, and the corresponding part of the wind shielding and direction adjusting assembly 6 is a circular arc segment. For example, the wind shielding and direction adjusting assembly 6 is an annular baffle. It can be understood that the shielding length L0 formed by the shielding part is the same as the arc length of the wind shielding and direction adjusting assembly 6, as shown in Figure 8 A shown. The air guiding part of the air guide ring assembly 5 is the part not blocked by the wind shielding and direction adjusting assembly 6, and the length of the air guiding part is Lf, as shown in Figure 8 B shown. The circumferential length L of the air guide ring assembly 5 is the sum of L0 and Lf.

[0095] It can be understood that the wind shielding and direction adjusting assembly 6 can block different positions in the circumferential direction of the air guide ring assembly 5 according to the user's requirement for the air outlet direction, and the part not blocked by the wind shielding and direction adjusting assembly 6 is the air guiding part. That is, the air guiding part and the shielding part of the air guide ring assembly 5 are not fixed.

[0096] Optionally, the shielding length L0 can be 0.25L, 0.4L, 0.5L, 0.75L, 0.8L, etc.

[0097] Optionally, the wind shielding and direction adjusting assembly 6 includes a rotatable plate group and a driving and rotating assembly. The rotatable plate group is rotatably arranged at the air guide ring assembly 5 to block part of the air guide ring assembly 5; the driving and rotating assembly is used to drive the rotatable plate group to rotate around the circumferential direction of the air guide ring assembly 5 to adjust the blocking position of the rotatable plate group on the air guide ring assembly 5.

[0098] The driving and rotating assembly includes a driving motor and a gear and a rack that rotate under the drive of the driving motor. The rotatable plate group can rotate around the circumferential direction of the air guide ring assembly 5 under the drive of the gear and the rack.

[0099] Optionally, the housing 1 includes a front housing part 11 provided with a front air outlet 102. Among them, a first track 71 is provided on the inner wall 111 of the front housing part, and the first end 601 of the rotatable plate group can rotate along the first track 71.

[0100] As shown in Figure 4 and Figure 7 shown, the first track 71 is a circular groove-shaped track, and a protrusion is provided at the first end 601 of the rotatable plate group. The protrusion can rotate in the first track 71. Optionally, the rack is arranged at the protrusion of the first end 601 of the rotatable plate group.

[0101] Optionally, the air guide ring assembly 5 includes a first air guide end 53 close to the front housing portion 11 and a second air guide end 54 opposite to the first air guide end 53. Among them, a fixed air duct partition 8 is provided at the second air guide end 54, and a second track 81 is provided on the fixed air duct partition 8. The second end 602 of the rotatable plate group can rotate along the second track 81.

[0102] A fixed air duct partition 8 is provided on one side of the second air guide end 54 of the air guide ring assembly 5. Optionally, the fixed air duct partition 8 is arranged in the vertical direction. The second track 81 is a circular track groove opened on the fixed air duct partition 8. As Figure 4 shown, the second end 602 of the rotatable plate group is inserted into the groove-shaped second track 81, which improves the rotation stability and shielding stability of the rotatable plate group. Optionally, the fixed air duct partition 8 has a certain thickness, so that the opening depth of the second track 81 can be appropriately increased.

[0103] Optionally, the fixed air duct partition 8 includes a partition bottom end 801 at the lower part, and among them, the setting height of the first air wheel air outlet 213 is higher than the partition bottom end 801.

[0104] As Figure 9 shown, the setting height of the first air wheel air outlet 213 is higher than the partition bottom end 801 of the fixed air duct partition 8. In this way, the air blown out from the first air wheel air outlet 213 can be concentrated and sent to the air guide ring assembly 5, and can selectively flow out from the air guide part of the air guide ring assembly 5.

[0105] Optionally, the rotatable plate group includes a first rotating plate 61 and a second rotating plate 62.

[0106] In the embodiment of the present disclosure, the rotatable plate group includes a first rotating plate 61 and a second rotating plate 62. Optionally, the first rotating plate 61 and the second rotating plate 62 are not connected to each other, and different motors can be respectively used to drive their rotation.

[0107] Optionally, the first rotating plate 61 and the second rotating plate 62 can be driven to rotate to adjacent positions, so that the first rotating plate 61 and the second rotating plate 62 are in contact with each other, and jointly play a role in adjusting the air outlet direction of the front air outlet 102, as Figure 10 shown in B in

[0108] Optionally, the first rotating plate 61 can be driven to rotate to the first position of the air guide ring assembly 5, and the second rotating plate 62 can be driven to rotate to the second position of the air guide ring assembly 5, and the first rotating plate 61 and the second rotating plate 62 are spaced apart. The first rotating plate 61 and the second rotating plate 62 enable the air guide ring assembly 5 to have two spaced-apart air guiding portions, and the air blown out from the first air wheel air outlet 213 can be sent out after the air direction is adjusted through these two spaced-apart air guiding portions, improving the diversification of the air direction adjustment of the air outlet 102 by the wind shielding and direction adjusting assembly 6.

Optionally, the second rotating plate 62 can be overlapped with the first end in the circumferential direction of the first rotating plate 61 to adjust the air outlet direction of the front air outlet 102, and the size of the overlapping portion between the second rotating plate 62 and the first rotating plate 61 can be further adjusted to adjust the air outlet range in this air outlet direction; similarly, the second rotating plate 62 can be overlapped with the second end in the circumferential direction of the first rotating plate 61 to adjust the air outlet direction of the front air outlet 102, and the size of the overlapping portion between the second rotating plate 62 and the first rotating plate 61 can be further adjusted to adjust the air outlet range in this air outlet direction. As Figure 11 shown.

[0110] Optionally, the driving rotating assembly includes a first driving motor for driving the first rotating plate 61 to rotate and a second driving motor for driving the second rotating plate 62 to rotate.

[0111] The first driving motor and the second driving motor are respectively used to drive the first rotating plate 61 and the second rotating plate 62 to rotate, so that the first rotating plate 61 and the second rotating plate 62 cooperate to enable the front air outlet 102 to achieve different air outlet directions.

[0112] Optionally, the shielding length formed by the first rotating plate 61 on the air guide ring assembly 5 is the first shielding length L1, the shielding length formed by the second rotating plate 62 on the air guide ring assembly 5 is the second shielding length L2, and the circumferential length of the air guide ring assembly 5 is L, where 0.25L ≤ L1 < 0.5L; and / or 0.25L ≤ L2 < 0.5L.

[0113] It can be understood that the first shielding length L1 is the arc length of the first rotating plate 61. Optionally, L1 can be 0.25L, 0.3L or 0.4L; similarly, the second shielding length L2 is the arc length of the second rotating plate 62, and L2 can be 0.25L, 0.3L or 0.4L.

[0114] Optionally, L1 > L2.

[0115] In an embodiment of the present disclosure, the first shielding length L1 of the first rotating plate 61 is greater than the second shielding length L2 of the second rotating plate 62. In this way, the second rotating plate 62 can be used as an extension plate or a fine adjustment plate of the first rotating plate 61. The air outlet direction of the front air outlet 102 is adjusted by the first rotating plate 61, and further, the air outlet range of the front air outlet 102 in this air outlet direction is adjusted by adjusting the overlapping position and overlapping area of the second rotating plate 62 in the circumferential direction of the first rotating plate 61.

[0116] Optionally, the rotation trajectory of the first rotating plate 61 is a first rotation trajectory, and the rotation trajectory of the second rotating plate 62 is a second rotation trajectory, wherein the first rotation trajectory is located outside the second rotation trajectory.

[0117] The first rotation trajectory is a first circle, and the second rotation trajectory is a second circle. The first rotation trajectory can overlap with the second rotation trajectory, as Figure 10 shown. Optionally, the first rotation trajectory can also be located outside the second rotation trajectory. In this way, the first rotation trajectory and the second rotation trajectory do not overlap with each other, and further, the first rotating plate 61 and the second rotating plate 62 can be rotated to a position where they at least partially overlap, as Figure 11 shown.

[0118] Optionally, the first rotating plate 61 is disposed on the outer side 51 of the air guide, and the second rotating plate 62 is disposed on the inner side 52 of the air guide.

[0119] The first rotating plate 61 and the second rotating plate 62 can be respectively disposed on the outer side 51 of the air guide and the inner side 52 of the air guide of the air guide ring assembly 5. For example, the first rotating plate 61 is closely disposed on the outer side 51 of the air guide, and the second rotating plate 62 is closely disposed on the inner side 52 of the air guide.

[0120] Optionally, a first outer track 711 and a first inner track 712 disposed inside the first outer track 711 are provided on the inner wall 111 of the front housing portion. Moreover, the first end of the first rotating plate 61 can rotate along the first outer track 711, and the first end of the second rotating plate 62 can rotate along the first inner track 712.

[0121] Two circular tracks are provided on the inner wall 111 of the front housing portion, which are the first outer track 711 and the first inner track 712 respectively, and the first inner track 712 is located inside the first outer track 711. In this way, the first rotating plate 61 and the second rotating plate 62 can be rotated to a position where they at least partially overlap.

[0122] Optionally, the fixed air duct partition 8 is provided with a second outer track and a second inner track disposed inside the second outer track. Moreover, the second end of the first rotating plate 61 can rotate along the second outer track, and the second end of the second rotating plate 62 can rotate along the second inner track.

[0123] The fixed air duct partition 8 is provided with two circular tracks, namely the second outer track and the second inner track, and the second inner track is located inside the second outer track.

[0124] Optionally, the housing 1 is further provided with a side air outlet 103 for blowing air to the side, and the fan assembly further includes a second fan 22 communicated with the side air outlet 103.

[0125] The embodiment of the present disclosure also provides an air conditioner indoor unit having an air duct switching component 4.

[0126] It can be understood that the first fan can be vertically arranged in the housing, such as Figure 2 shown; Figures 16 to 27 the first fan in Figures 16 to 27 is horizontally arranged, and the first fan in

[0127] can also be adjusted to be vertically arranged.

[0128] 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 the upper part of the housing 1 is provided with a front air outlet 102, and the side part of the housing 1 is provided with a side air outlet 103; the first fan 21 is communicated with the front air outlet 102 for blowing air forward; the second fan 22 is communicated with the side air outlet 103 for blowing air to the side; 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.

[0129] 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 and the rear housing part are oppositely arranged. Among them, the air inlet 101 is opened on the rear housing part, and an air inlet grille is arranged at the air inlet 101; the front air outlet 102 is opened on 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, and 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 part of the front housing part 11.

[0130] Optionally, the front air outlet 102 is arranged 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 strip-shaped.

[0131] 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, the second blower 22 is a cross-flow blower, and the centrifugal blower is disposed above the cross-flow blower.

[0132] The indoor air conditioner provided by the embodiment of the present disclosure further includes an air duct switching member 4. The air duct switching member 4 is disposed between the first heat exchange portion 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 member 4 can be controlled to be in a blocking state that blocks the first heat exchange portion 31 and the first blower 21, and the air duct switching member 4 forms an air duct between the first heat exchange portion 31 and the second blower 22. At this time, the air-conditioning air with heat or cold generated by the first heat exchange portion 31 can be sent out from the side air outlet 103 through the second blower 22.

[0133] 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 closed, the heat or cold generated by the first heat exchange portion 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 to timely discharge the cold of the first heat exchange portion 31 are avoided.

[0134] 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 member 4 can be controlled to be in a conducting state. At this time, the air duct between the first heat exchange portion 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 portion 31 can be sent out from the front air outlet 102 after passing through the first blower 21.

[0135] Optionally, in the vertical direction, the second heat exchange portion 32 of the heat exchanger 3 is disposed opposite to the second blower 22, that is, the second heat exchange portion 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 portion 31. When the air duct switching member 4 is controlled to be in a conducting state, the air duct switching member 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 member 4 separates the air-conditioning air generated by the first heat exchange portion 31 and the second heat exchange portion 32 of the heat exchanger 3, so that the air-conditioning air generated by the first heat exchange portion 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 portion 32 is sent out from the side air outlet 103 after passing through the second blower 22. As Figure 21 shown.

[0136] 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.

[0137] Optionally, the air duct switching component 4 includes a movable air duct part and a driving and switching assembly. The driving and switching assembly is used to drive the movable air duct part to rotate or move. The first blower 21 includes a first blower housing 211, and a first wind wheel air inlet 212 is formed in the first blower housing 211. Wherein, when the driving and switching 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 wind wheel air inlet 212.

[0138] Optionally, the driving and switching 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 and switching assembly so that the movable air duct part rotates to the blocking state or the conducting state.

[0139] 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 wind wheel air inlet 212, and at the same time forms an air duct between the first heat exchange part 31 and the second blower 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 blower 22. As Figure 18 shown.

[0140] 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 blower 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 blower housing 211 is less than or equal to a second preset distance. As Figure 25 and Figure 28 shown.

[0141] Optionally, the first rotating end 411 is the first rotation center 4101 of the first rotating air duct plate 41. Optionally, the third 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.

[0142] 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 Figure 21 shown; 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, asFigure 18 As shown. 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°.

[0143] 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 Figure 28 shown in FIG. A in this disclosure embodiment, 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 Figure 25 shown in FIG. A in this disclosure embodiment.

[0144] 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 Figure 28 shown in FIG. A in this disclosure embodiment, 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 Figure 25 shown in FIG. A in this disclosure embodiment.

[0145] Optionally, the first rotating air duct plate 41 is plate-shaped.

[0146] Optionally, the first rotating air duct plate 41 is flat plate-shaped, such as Figure 16As 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 fan 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 fan 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 fan 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 fan 21, improving the air supply effect of the first fan 21.

[0147] Optionally, the movable air duct part further includes a 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 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 fan 21.

[0148] 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 fan 21.

[0149] 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 fan 22.

[0150] 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 20 shown.

[0151] 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 16 to 20As 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 on 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 part of the remaining length of the first rotating air duct plate 41 exists. This part of the remaining length can be used to adjust the overlapping angle formed by the first rotating air duct plate 41 and the second rotating air duct plate 42.

[0152] Optionally, the overlapping angle A formed by 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°.

[0153] Optionally, the overlapping angle A formed by 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.

[0154] 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 constitute 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.

[0155] 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 form a first overlapping angle, or the first rotating air duct plate 41 and the second rotating air duct plate 42 can form a second overlapping angle.

[0156] 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 by 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 20 shown at A. 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.

[0157] 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.

[0158] Optionally, the second rotating air duct plate 42 is in the shape of a flat plate, as Figure 16 shown. Optionally, the second rotating air duct plate 42 is in the shape of an inward concave arc. It can be understood that when the second rotating air duct plate 42 is in the blocking state or the conducting state, the inward concave second rotating air duct plate 42 protrudes towards the side of the second fan 22. In this way, when the air duct switching component 4 forms a blocking state, the inward 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 fan 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 inward concave second rotating air duct plate 42 will not block the air-conditioning wind of the first heat exchange part 31, improving the air supply effect of the first fan 21.

[0159] 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 fan 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 30 shown.

[0160] 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 fan 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 fan 21 and is sent out from the front air outlet 102.

[0161] 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 in the horizontal direction.

[0162] Optionally, the second fan 22 includes an upper end of the second fan close to the fixed air duct plate 43. 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 generated by the fixed air duct plate 43 during the air guiding process is reduced. As Figure 25 shown.

[0163] 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 24 to 28 shown.

[0164] 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 20 shown.

[0165] 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 20 shown at B in.

[0166] 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.

[0167] Optionally, the air duct switching component 4 includes a movable air duct part and a driving and switching assembly. The movable air duct part includes a first rotating air duct plate 41 and a second rotating air duct plate 42; the driving and switching assembly includes a third driving motor and a fourth driving motor. The third driving motor is used to drive the first rotating air duct plate 41 to rotate, and the fourth driving motor is used to drive the second rotating air duct plate 42 to rotate. When the air duct switching component 4 is in the blocking state, the first rotating air duct plate 41 and the second rotating air duct plate 42 overlap to block the first heat exchange part 31 and the first fan 21.

[0168] In the embodiment of the present disclosure, the third driving motor and the fourth 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 third driving motor can be installed on the inner wall of the housing 1, and the fourth driving motor can also be installed on the inner wall of the housing 1.

[0169] When the inner wall of the first rotating air duct plate 41 overlaps with the second rotating air duct plate 42, the fourth driving motor can be controlled to drive the second rotating air duct plate 42 to rotate to the overlapping position first, and then the third driving motor can be controlled to drive the first rotating air duct plate 41 to overlap with the second rotating air duct plate 42.

[0170] Optionally, in the extending 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, wherein the first length H3 is less than or equal to the first distance H4.

[0171] As Figure 25 shown, the length of the first rotating air duct plate 41 is the first length H3, as Figure 28 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, so that 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 the vertical state.

[0172] Optionally, the first rotating air duct plate 41 includes a first rotating end 411 and a second rotating end 412, and the first rotating end 411 is the first rotation center 4101 of the first rotating air duct plate 41, wherein the first rotating end 411 is arranged at the first heat exchange end 311. Optionally, H3 = H4, as Figure 26 shown in A in

[0173] Optionally, in 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, wherein the second length H5 is less than or equal to the second distance H6.

[0174] 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, so that 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 the horizontal state. As Figure 26 shown.

[0175] 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.

[0176] Optionally, when the air duct switching component 4 is in the blocking state, the third drive motor drives the first rotating air duct plate 41 to rotate to an inclined state, the fourth drive 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 to form a non-horizontal air duct plate section 401.

[0177] 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.

[0178] 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 on the same horizontal line, improving the air guiding stability when the air duct switching component 4 is in the conducting state.

[0179] 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.

[0180] 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.

[0181] 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.

[0182] 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-conditioning 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 in the first heat exchange portion 31.

[0183] The embodiment of the present disclosure also provides an air conditioner, which can also be called an air-conditioning, including the air conditioner indoor unit as described above.

[0184] The embodiment of the present disclosure provides a method for controlling an air conditioner indoor unit, including:

[0185] 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.

[0186] 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.

[0187] 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.

[0188] 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, it 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. In one example, when the difference between the set temperature of the air conditioner and the room temperature is large, it means that the air conditioner needs to quickly adjust the room temperature to reach the set value. At this time, control the air duct switching component to be in the 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 means that the room temperature is already close to the set value. At this time, control the air duct switching component to be in the blocked state, block the first heat exchange part and the first fan, and make the air after heat exchange with the first heat exchange part be sent out from the side air outlet, so as to provide a more comfortable air supply experience for users and reduce the discomfort caused by direct air blowing at the same time.

[0189] 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, which not only enriches the air supply dimension, expands the space coverage range, but also can adjust the air supply direction according to the demand to avoid direct air blowing at the user. Therefore, 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.

[0190] 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:

[0191] 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.

[0192] 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 blocking state.

[0193] 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 through 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 simultaneous air supply method 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 through 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, while reducing the discomfort caused by direct air blowing and maintaining the stability of the room temperature.

[0194] 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.

[0195] In this solution, the temperature difference threshold can be set in advance. As an example, the temperature difference threshold can be 2°C.

[0196] Optionally, the temperature difference threshold is dynamically adjusted according to the following information:

[0197] The current time information; or,

[0198] The current outdoor environmental parameter information; or,

[0199] The current indoor environmental parameter information; or,

[0200] The current season information; or,

[0201] The current geographical location information.

[0202] In one example, the temperature difference threshold can be adjusted according to the current time information. For example, at night or in the user-set sleep mode, the temperature difference threshold can be appropriately reduced so that the air conditioner switches to a softer air supply mode at a smaller temperature difference, reducing the interference of night air supply 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 user's higher temperature requirements during activities.

[0203] 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 is 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 the best balance between dehumidification and cooling or heating of the air conditioner, improving the user's comfort.

[0204] 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-saving indoor environment for users.

[0205] Optionally, the air duct switching component includes a movable air duct part, and the movable air duct part includes a first rotating air duct plate and a second rotating air duct plate. When the air duct switching component is in a blocking state, the first rotating air duct plate overlaps with the second rotating air duct plate so that the first rotating air duct plate and the second rotating air duct plate jointly block the first heat exchange part and the first fan. The method further includes:

[0206] S91, the air conditioner obtains the rotation speed of the second fan.

[0207] 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.

[0208] 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, where the first rotation speed is greater than the second rotation speed, and the first overlapping angle is less than the second overlapping angle.

[0209] Specifically, when the second overlapping angle is smaller 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 larger than that at the first overlapping angle. In this way, when the second fan operates at the first speed with a relatively high speed, the first rotating air duct plate and the second rotating air duct plate form an air duct with a larger volume, thereby improving the delivery effect of the air-conditioning air from the first heat exchange part through the second fan and out of the side air outlet.

[0210] Optionally, the included angle between the first rotating air duct plate and the horizontal direction can be adjusted, and the included angle between the second rotating air duct plate and the horizontal direction can be adjusted to make the first rotating air duct plate and the second rotating air duct plate form the first overlapping angle, or to make the first rotating air duct plate and the second rotating air duct plate form the second overlapping angle.

[0211] Optionally, the air duct switching component includes a movable air duct part, and the movable air duct part 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 to block the first heat exchange part and the first fan together. The method further includes:

[0212] The air conditioner determines the user's air supply intention, and the air supply intention includes mild cold air supply and strong cold air supply.

[0213] When the user's air supply intention is mild cold air supply, the air conditioner increases the overlapping angle between the first rotating air duct plate and the second rotating air duct plate.

[0214] When the user's air supply intention is strong cold air supply, the air conditioner decreases the overlapping angle between the first rotating air duct plate and the second rotating air duct plate.

[0215] 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 to block the first heat exchange part and the first fan together, so that the air after heat exchange in 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, the method further 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.

[0216] When the air conditioner determines the user's air supply intention, it will adjust the air duct accordingly according to the mode selected by the user. If the user selects the mild cooling 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 volume of the air duct 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-conditioned air cooled by the first heat exchange part passes through the second fan and is sent out from the side air outlet, the reduction of the air volume and air speed makes the intensity of the blown cold air weaken, thus realizing the gentle breeze effect. This gentle breeze effect can provide the user with a more gentle and comfortable cold air experience, which is suitable for use in scenarios where the temperature is appropriate but a slight temperature drop is needed.

[0217] On the contrary, when the user selects the strong cooling 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 volume of the air duct 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-conditioned 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 stronger, thus realizing the strong cooling effect. This strong cooling effect can quickly reduce the indoor temperature, which is suitable for use in hot weather or scenarios where rapid cooling is required.

[0218] In the process of realizing 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 according to the feedback information to ensure that the air duct adjustment conforms to the user's air supply intention. At the same time, the control system will also coordinate and adjust the rotation speed of the fan according to the angle change of the air duct plate to further optimize the air supply effect. For example, in the mild cooling air supply mode, the rotation speed of the fan may be appropriately reduced to further reduce the air volume and air speed; while in the strong cooling air supply mode, the rotation speed of the fan may be appropriately increased to enhance the air supply effect.

[0219] Optionally, the method further includes:

[0220] The air conditioner determines the user's air supply intention, and the air supply intention includes normal temperature air supply, mild cooling air supply and strong cooling air supply.

[0221] 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 blocking state and starts the first fan to provide the user with normal temperature gentle breeze through the front air outlet.

[0222] When the user's air supply intention is gentle 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 normal-temperature gentle air, and the side air outlet outputs cold air, so as to provide gentle air for the user through the mixing of the two.

[0223] When the user's air supply intention is strong cold air supply, the air conditioner controls the air duct switching component to switch to the 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.

[0224] In this solution, the user's air supply intention is subdivided into three modes: normal-temperature air supply, gentle 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.

[0225] When the user's air supply intention is gentle cold air supply, the air conditioner also controls the air duct switching component to be in a blocked state, but 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 gentle cold air supply effect is provided for the user. This mode is suitable for use in scenarios where the user needs to slightly cool down but does not want to be blown by strong cold air, such as when the indoor temperature is high but the user is sensitive to cold air.

[0226] When the user's air supply intention is strong cold air supply, 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 unblocked, and the first fan and the second fan run 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.

[0227] With this solution, users can choose different air supply modes according to their comfort preferences, and the air conditioner achieves the corresponding air supply effect through intelligent control. This intelligent control method not only improves the user 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 precisely control the air volume and wind speed, thus providing a more comfortable and uniform air supply experience for users while quickly cooling or heating, significantly improving the overall performance of the air conditioner and user satisfaction.

[0228] Optionally, the air conditioner determines the user's air supply intention, including:

[0229] The air conditioner obtains the key value information, environmental parameter data, human body state data, and historical habit data input by the user.

[0230] 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.

[0231] 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 the environmental parameter data through built-in or external sensors, such as the indoor temperature, humidity, and air quality. If the indoor temperature is 28°C and the humidity is 60%, the air conditioner will combine these data to further judge that the user may need a stronger cooling effect. In addition, the air conditioner can also obtain the human body state data through smart wearable devices or body sensors, such as the user's body temperature and activity status. 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 precisely determine the user's air supply intention and achieve personalized and intelligent air supply control.

[0232] 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.

[0233] By using the device for controlling the air conditioner indoor unit provided by the embodiment of the present disclosure and utilizing 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 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 blowing, meets the user's personalized needs for multi-dimensional air supply, and improves the use experience and space adjustment efficiency of the air conditioner.
