[0025] In some embodiments, the air conditioner includes the aforementioned indoor unit of the air conditioner.

[0026] The indoor unit of the air conditioner and the air conditioner provided by the embodiments of the present disclosure can achieve the following technical effects:

[0027] The indoor unit of the air conditioner includes a housing, a fan assembly, an air guide ring assembly, and a wind blocking and direction adjusting assembly. The housing is provided with a front air outlet for blowing air forward. The fan assembly includes a first fan communicated with the front air outlet. The first fan includes a first fan housing, and the first fan housing is provided with a first wind wheel air outlet. The air guide ring assembly is disposed in a first air duct between the first wind wheel air outlet and the front air outlet. The wind blocking and direction adjusting assembly is used to block a part of the air guide ring assembly to adjust the air outlet direction of the front air outlet.

[0028] In the indoor unit of the air conditioner provided by the embodiments of the present disclosure, a wind blocking and direction adjusting assembly is disposed in the first air duct between the first wind wheel air outlet and the front air outlet.

[0029] Moreover, in the prior art, an air outlet grille is provided at the front air outlet to adjust the air outlet direction of the front air outlet. However, this air outlet direction adjustment method realizes the adjustment of the air outlet direction by blocking the air outlet through the air outlet grille, resulting in a large air loss.

[0030] Compared with the method of adjusting the air outlet grille at the front air outlet, in the air conditioner indoor unit provided by the embodiments of the present disclosure, the wind blocking and direction adjusting assembly is arranged at the air guide ring assembly, so that the air blown out by the first fan can be selectively blown out through the unobstructed part of the air guide ring assembly. That is, the air blown out by the first fan 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.

[0031] At the same time, the rotatable plate group of the wind blocking and direction adjusting assembly includes a first rotating plate and a second rotating plate. Using two rotating plates to adjust the air outlet direction of the front air outlet at the same time improves the diversification of the air outlet direction of the front air outlet.

[0079] It should be noted that, without conflict, the embodiments in this disclosure and the features in the embodiments can be combined with each other.

[0080] The embodiment of the present disclosure provides a cabinet-type air conditioner indoor unit, which can also be called a floor-standing air conditioner indoor unit or a vertical air conditioner indoor unit, etc.

[0081] 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 the first fan housing 211 is provided with a first impeller air outlet 213. The wind guide ring assembly 5 is arranged in the first air duct between the first impeller air outlet 213 and the front air outlet 102. The wind blocking and direction adjusting assembly 6 is used to block part of the wind guide ring assembly 5 to adjust the air outlet direction of the front air outlet 102.

[0082] Optionally, the front air outlet 102 provided on the housing 1 can be a circular air outlet or a square air outlet. Optionally, the front air outlet 102 is provided on the upper part of the housing 1.

[0083] Optionally, the wind guide ring assembly 5 includes at least two wind guide rings with a through middle. The multiple 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 adjacent two wind guide rings. The jet port guides the air from the first impeller air outlet 213 of the first fan 21 to the front air outlet 102 to blow air forward.

[0084] Optionally, the first fan 21 is a centrifugal fan and is arranged at the lower part of the wind guide ring assembly 5. Optionally, the first impeller air outlet 213 is perpendicular to the wind guide ring assembly 5. The wind guide ring has an arc-shaped wind guiding surface. After the air blown out from the first impeller air outlet 213 is redirected by the arc-shaped wind guiding surface of the wind guide ring, it is sent out from the front air outlet 102.

[0085] The air conditioner indoor unit provided by the embodiment of the present disclosure is also provided with a wind blocking and direction adjusting assembly 6. The wind blocking and direction adjusting assembly 6 is used to block part of the wind guide ring assembly 5, so that the air blown out from the first impeller 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.

[0086] Optionally, the wind shielding and direction adjusting component 6 shields a circumferential part of the air guiding ring component 5. For example, the wind shielding and direction adjusting component 6 shields the lower part of the circumference of the air guiding ring component 5. In this way, the wind blown out from the first wind wheel air outlet 213 blows out through the upper part of the circumference of the air guiding ring component 5, so that the direction of the wind blown out from the front air outlet 102 is inclined downward, as Figure 5 shown. Or, the wind shielding and direction adjusting component 6 shields the upper part of the circumference of the air guiding ring component 5. In this way, the wind blown out from the first wind wheel air outlet 213 blows out through the lower part of the circumference of the air guiding ring component 5, so that the direction of the wind blown out from the front air outlet 102 is inclined upward, as Figure 6 shown.

[0087] It can be understood that the wind shielding and direction adjusting component 6 can also shield the side part of the circumference of the air guiding ring component 5. For example, it shields the left side or the right side of the air guiding ring component 5, so that the direction of the wind blown out from the front air outlet 102 is inclined to the right or to the left.

[0088] It can be seen that the air conditioner indoor unit provided with the wind shielding and direction adjusting component 6 in the embodiment of the present disclosure can adjust the air outlet direction of the front air outlet 102 in all directions such as up, down, left, and right, improving the diversification of the air outlet direction of the front air outlet 102. Optionally, the wind shielding and direction adjusting component 6 can rotate circumferentially around the air guiding ring component 5 to shield different positions on the circumference of the air guiding ring component 5 according to the air outlet requirements of the user, thereby adjusting the air outlet direction of the front air outlet 102.

[0089] Moreover, the wind shielding and direction adjusting component 6 is arranged at the air guiding ring component 5. In this way, the wind blown out from the first wind wheel air outlet 213 can be selectively led out through the unshielded part of the air guiding ring component 5, and there will be no problems such as air stagnation and large air volume loss.

[0090] Optionally, the air guiding ring component 5 includes an outer air guiding part 51 close to the first wind wheel air outlet 213 and an inner air guiding part 52 close to the front air outlet 102. Among them, the wind shielding and direction adjusting component 6 is arranged on the outer air guiding part 51 or the inner air guiding part 52.

[0091] The outer air guiding part 51 can be understood as the outer ring of the air guiding ring in the air guiding ring component 5, and the inner air guiding part 52 can be understood as the inner ring of the air guiding ring in the air guiding ring component 5, as Figure 7 shown. In the embodiment of the present disclosure, the wind shielding and direction adjusting component 6 can be arranged on the inner air guiding part 52 or the outer air guiding part 51 of the air guiding ring component 5 to shield the wind from the inner air guiding part 52 or the outer air guiding part 51. As Figure 7 shown, the wind shielding and direction adjusting component 6 is arranged on the outer air guiding part 51.

[0092] Optionally, the wind shielding and direction adjusting component 6 abuts against the outer air guiding part 51 or the inner air guiding part 52 of the air guiding ring component 5.

[0093] When the windshield orientation adjustment component 6 is disposed on the outer side 51 of the air guide, the windshield orientation adjustment component 6 abuts against the outer side 51 of the air guide. It can also be understood that there is no air passing gap between the windshield orientation adjustment component 6 and the outer side 51 of the air guide; when the windshield orientation adjustment component 6 is disposed on the inner side 52 of the air guide, the windshield orientation adjustment component 6 abuts against the inner side 52 of the air guide. It can also be understood that there is no air passing gap between the windshield orientation adjustment component 6 and the inner side 52 of the air guide. In this way, the shielding effect of the windshield orientation adjustment component 6 on the shielding part of the air guide ring component 5 is improved.

[0094] Optionally, the air guide ring component 5 includes an air guiding part and a shielding part that forms a shield with the windshield orientation adjustment component 6. The air blown out from the first wind wheel air outlet 213 is adjusted in direction by the air guiding part of the air guide ring component 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 component 5 is L, and 0.25L ≤ L0 ≤ 0.8L.

[0095] The air guide ring in the air guide ring component 5 is circular, and the corresponding windshield orientation adjustment component 6 is a circular arc segment. For example, the windshield orientation adjustment component 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 windshield orientation adjustment component 6, as shown in Figure 8 A shown. The air guiding part of the air guide ring component 5 is the part not shielded by the windshield orientation adjustment component 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 component 5 is the sum of L0 and Lf.

[0096] It can be understood that the windshield orientation adjustment component 6 can shield different positions in the circumferential direction of the air guide ring component 5 according to the user's requirement for the air outlet direction, and the part not shielded by the windshield orientation adjustment component 6 is the air guiding part. That is, the air guiding part and the shielding part of the air guide ring component 5 are not fixed.

[0097] Optionally, the shielding length L0 can be 0.25L, 0.4L, 0.5L, 0.75L, 0.8L, etc.

[0098] Optionally, the windshield orientation adjustment component 6 includes a rotatable plate group and a driving rotation component. The rotatable plate group is rotatably disposed at the air guide ring component 5 to shield a part of the air guide ring component 5; the driving rotation component is used to drive the rotatable plate group to rotate around the circumferential direction of the air guide ring component 5 to adjust the shielding position of the rotatable plate group on the air guide ring component 5.

[0099] The driving rotation component includes a driving motor and a gear and a rack that rotate driven by the driving motor. The rotatable plate group can rotate around the circumferential direction of the air guide ring component 5 driven by the gear and the rack.

[0100] Optionally, the housing 1 includes a front housing portion 11 provided with a front air outlet 102, wherein a first track 71 is provided on the inner wall 111 of the front housing portion, and the first end 601 of the rotatable plate group can rotate along the first track 71.

[0101] As Figure 4 and Figure 7 shown, the first track 71 is a circular groove track, and a protrusion is provided at the first end 601 of the rotatable plate group, and the protrusion can rotate within the first track 71. Optionally, the rack is provided at the protrusion of the first end 601 of the rotatable plate group.

[0102] 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, wherein 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, and the second end 602 of the rotatable plate group can rotate along the second track 81.

[0103] 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.

[0104] Optionally, the fixed air duct partition 8 includes a partition bottom end 801 at the lower part, wherein the installation height of the first air wheel air outlet 213 is higher than that of the partition bottom end 801.

[0105] As Figure 9 shown, the installation height of the first air wheel air outlet 213 is higher than that of 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.

[0106] Optionally, the rotatable plate group includes a first rotating plate 61 and a second rotating plate 62.

[0107] 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 the rotation.

[0108] 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. AsFigure 10 as shown in B.

[0109] 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 parts, 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 parts, improving the diversification of the air direction adjustment of the front air outlet 102 by the wind blocking and direction adjusting assembly 6. As Figure 10 shown in A.

Optionally, the second rotating plate 62 can be overlapped with the first end of 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 part 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 of 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 part 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] Optionally, L1 > L2.

[0116] In the embodiments 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.

[0117] 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, where the first rotation trajectory is located outside the second rotation trajectory.

[0118] 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 at least partially overlapping positions, as Figure 11 shown.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] Two circular tracks are provided on the inner wall 111 of the front housing portion, namely the first outer track 711 and the first inner track 712, 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 at least partially overlapping positions.

[0123] 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, and the second end of the first rotating plate 61 is rotatable along the second outer track, and the second end of the second rotating plate 62 is rotatable along the second inner track.

[0124] 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.

[0125] Optionally, the housing 1 is further provided with a side air outlet 103 for sending air to the side, and the fan assembly further includes a second fan 22 communicated with the side air outlet 103.

[0126] The embodiment of the present disclosure further provides an air conditioner indoor unit having an air duct switching member 4.

[0127] It can be understood that the first fan can be vertically arranged in the housing, as Figure 2 shown; Figures 16 to 27 the first fan in Figures 16 to 27 is horizontally arranged, and the first fan in

[0128] can also be adjusted to be vertically arranged.

[0129] 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 member 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 sending air forward; the second fan 22 is communicated with the side air outlet 103 for sending 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 member 4 is disposed between the first heat exchange part 31 and the first fan 21, and the air duct switching member 4 can be in a blocking state and a conducting state.

[0130] Optionally, the housing 1 includes a front housing portion 11, a rear housing portion, and a side housing portion 12. The front housing portion 11 is disposed opposite to the rear housing portion. Among them, the air inlet 101 is opened on the rear housing portion, 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 portion 11. The side air outlets 103 include a first side air outlet and a second side air outlet. The side air outlets 103 can be opened on the side housing portion 12, or the side air outlets 103 can also be opened on the side portion of the front housing portion 11.

[0131] Optionally, the front air outlet 102 is disposed above the side air outlets 103. Optionally, the front air outlet 102 can be circular, square, or other regular or irregular shapes; the side air outlets 103 are strip-shaped.

[0132] 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.

[0133] 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 portion 31 of the heat exchanger 3 and the first blower 21. When only the side air outlets 103 need to supply air, at this time, the first blower 21 for supplying air to the front air outlet 102 is in the closed state, and the second blower 22 for supplying air to the side air outlets 103 is in the open state. It is possible to control the air duct switching component 4 to be in a blocking state that blocks the first heat exchange portion 31 and the first blower 21, and the air duct switching component 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 outlets 103 through the second blower 22.

[0134] It can be seen that for the indoor air conditioner provided by the embodiment of the present disclosure, when only the side air outlets 103 need to supply air, with the first blower 21 turned off, the heat or cold generated by the first heat exchange portion 31 can be sent out from the side air outlets 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 portion 31 to discharge cold air in time are avoided.

[0135] When the user needs to supply air from both the front air outlet 102 and the side air outlets 103 at the same time, it is possible to control the air duct switching component 4 to be in the 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.

[0136] Optionally, in the vertical direction, the second heat exchange part 32 of the heat exchanger 3 is arranged opposite to the second fan 22, that is, the second heat exchange part 32 and the second fan 22 are arranged at approximately the same height; optionally, the first fan 21 is arranged above the first heat exchange part 31. When the air duct switching component 4 is in the 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 fan 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 fan 22. As Figure 21 shown.

[0137] 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.

[0138] 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 fan 21 includes a first fan housing 211, and a first wind wheel air inlet 212 is formed in the first fan housing 211. Among them, 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.

[0139] Optionally, the driving and switching assembly can include a driving motor, and the movable air duct part can 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.

[0140] 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 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 18 shown.

[0141] 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. AsFigure 25 and Figure 28 as shown

[0142] Optionally, the first rotating end 411 is the first rotation center 4101 of the first rotating air duct plate 41. Optionally, the third drive motor for driving the rotation of the first rotating air duct plate 41 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 a conducting state or a blocking state.

[0143] 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, as Figure 18 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°.

[0144] 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 Figure A. 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 Figure 25 shown in Figure A.

[0145] 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 Figure A. 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 Figure 25 shown in Figure A.

[0146] Optionally, the first rotating air duct plate 41 is in a plate shape.

[0147] Optionally, the first rotating air duct plate 41 is in the shape of a flat plate, as Figure 16 shown. Optionally, the first rotating air duct plate 41 is in a convex arc shape. 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 towards the side of 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 towards 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 beneficial 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.

[0148] 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 blower 21.

[0149] 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.

[0150] 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.

[0151] 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.

[0152] 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 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 in 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.

[0153] 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°.

[0154] 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 fan 22. For example, when the rotational speed of the second fan 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 fan 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.

[0155] 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 fan 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 of the first heat exchange part 31 from the side air outlet 103 after passing through the second fan 22.

[0156] 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.

[0157] 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 20 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 supply effect of the air-conditioning air of the first heat exchange part 31 being sent out from the side air outlet 103 is improved.

[0158] 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.

[0159] 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 a 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 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 wind of the first heat exchange part 31, improving the air supply effect of the first blower 21.

[0160] 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 30 shown.

[0161] 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.

[0162] Optionally, the fixed air duct plate 43 is a fixedly arranged flat plate structure and does not need to rotate. The fixed air duct plate 43 can be used as an extension air duct plate of the second rotating air duct plate 42. Optionally, the fixed air duct plate 43 is arranged horizontally.

[0163] Optionally, the second blower 22 includes an upper end of the second blower close to the fixed air duct plate 43, where the distance between the fixed air duct plate 43 and the upper end of the second blower 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.

[0164] 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.

[0165] 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.

[0166] 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.

[0167] 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.

[0168] 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, and 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. Among them, 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 blower 21.

[0169] In the embodiments 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.

[0170] 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.

[0171] 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, where the first length H3 is less than or equal to the first distance H4.

[0172] 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 a vertical state.

[0173] 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, where the first rotating end 411 is arranged on the first heat exchange end 311. Optionally, H3 = H4, as Figure 26 shown in A in

[0174] 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.

[0175] 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 a horizontal state. As Figure 26 shown.

[0176] 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.

[0177] Optionally, when the air duct switching component 4 is in the blocking state, the third driving motor drives the first rotating air duct plate 41 to rotate to an inclined state, the fourth 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 to form a non-horizontal air duct plate section 401.

[0178] 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.

[0179] 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.

[0180] 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.

[0181] 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.

[0182] 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. 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.

[0183] 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 part 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 part 31.

[0184] 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.

[0185] The embodiment of the present disclosure provides a method for controlling an air conditioner indoor unit, including:

[0186] 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.

[0187] 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.

[0188] 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.

[0189] 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 the direct blowing of the air flow at the same time.

[0190] 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, avoiding the direct blowing of the air flow to the user. Therefore, while effectively expanding the air supply dimension, it significantly reduces the discomfort caused by the direct blowing of the air flow, meets the personalized needs of users for multi-dimensional air supply, and improves the use experience and space adjustment efficiency of the air conditioner.

[0191] Optionally, 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:

[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 greater than the temperature difference threshold, the air conditioner controls the air duct switching component to switch to the conducting state.

[0193] 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.

[0194] 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, reduce the discomfort caused by direct air blowing, and maintain the stability of the room temperature.

[0195] 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.

[0196] In this solution, the temperature difference threshold can be set in advance. As an example, the temperature difference threshold can be 2°C.

[0197] Optionally, the temperature difference threshold is dynamically adjusted according to the following information:

[0198] The current time information; or, the current outdoor environmental parameter information; or, the current indoor environmental parameter information; or, the current season information; or, the current geographical location information.

[0199] 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.

[0200] 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 that the air conditioner reaches the best balance between dehumidification and cooling or heating, improving the comfort of the user.

[0201] 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, realizing 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.

[0202] 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:

[0203] S91, the air conditioner obtains the rotation speed of the second fan.

[0204] 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.

[0205] 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.

[0206] 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 of the first heat exchange part from the side air outlet after passing through the second fan.

[0207] 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.

[0208] 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 and the second rotating air duct plate overlap to jointly block the first heat exchange part and the first fan. The method further includes:

[0209] The air conditioner determines the user's air supply intention, and the air supply intention includes slightly cold air supply and strongly cold air supply.

[0210] When the user's air supply intention is slightly cold air supply, the air conditioner increases the overlapping angle between the first rotating air duct plate and the second rotating air duct plate.

[0211] When the user's air supply intention is strongly cold air supply, the air conditioner decreases the overlapping angle between the first rotating air duct plate and the second rotating air duct plate.

[0212] 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 and the second rotating air duct plate overlap to jointly block the first heat exchange part and the first fan, 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.

[0213] 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 slightly 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 volume of the air duct formed between the first rotating air duct plate and the second rotating air duct plate smaller. Understandably, since the volume of the air duct decreases, 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 conditioner 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 air volume and air speed makes the intensity of the blown cold air weaken, thus achieving the gentle breeze effect. This gentle breeze effect can provide the user with a more gentle and comfortable cold air experience, and is suitable for use in scenarios where the temperature is appropriate but slight cooling is required.

[0214] On the contrary, when the user selects the strong cold air supply mode, the air conditioner will decrease 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 volume of the air duct 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 conditioner 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 air volume and air speed makes the intensity of the blown cold air strengthen, 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 cooling is required.

[0215] 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 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 cooperate with the adjustment of the fan speed 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 fan speed may be appropriately reduced to further reduce the air volume and air speed; while in the strong cold air supply mode, the fan speed may be appropriately increased to enhance the air supply effect.

[0216] Optionally, the method further includes:

[0217] The air conditioner determines the user's air supply intention, and the air supply intention includes normal temperature air supply, slightly cold air supply and strong cold air supply.

[0218] When the user's air supply intention is normal temperature air supply, the air conditioner controls the air duct switching component to be in the blocking state and starts the first fan to provide the user with normal temperature gentle breeze through the front air outlet.

[0219] 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 mix the two to provide gentle air for the user.

[0220] 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.

[0221] 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 through 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.

[0222] 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 at the same time. 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 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.

[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 a 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 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 cooling, such as during high-temperature periods in summer or when the user just enters the room and needs to quickly cool down.

[0224] 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.

[0225] Optionally, the air conditioner determines the user's air supply intention, including:

[0226] The air conditioner obtains the key value information, environmental parameter data, human body state data, and historical habit data input by the user.

[0227] 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.

[0228] 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 intelligent 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 precisely determine the user's air supply intention and achieve personalized and intelligent air supply control.

[0229] 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.

[0230] By using the device for controlling an air-conditioning indoor unit provided in the embodiments 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 achieve 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 requirements to avoid the air flow blowing directly at 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.
