It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0038] Unless otherwise specified, the term "a plurality of" means two or more.

[0039] In the embodiments of the present disclosure, the character " / " represents an "or" relationship between the preceding and following objects. For example, A / B represents: A or B.

[0040] The term "and / or" is a description of the association relationship between objects, which means that there can be three relationships. For example, A and / or B means: A or B, or, A and B, the three relationships.

[0041] The term "corresponding" can refer to an association relationship or a binding relationship. A and B correspond to each other means that there is an association relationship or a binding relationship between A and B.

[0042] In the embodiments of the present disclosure, "left", "right", "clockwise", "counterclockwise" are all relative to Figures 1 to 4 , andFigure 7 and Figure 8 In other words.

[0043] Combination Figures 1 to 4 As shown, this embodiment of the present disclosure provides an air conditioner. The indoor unit of the air conditioner includes: a housing 10, a heat exchanger 20, a volute 30, and a sealing baffle 40. A first air vent 11 and a second air vent 12 are respectively provided on two different surfaces of the housing 10. The air outlet directions of the first air vent 11 and the second air vent 12 are different. Optionally, the first air vent 11 is located on the side of the housing 10, serving as a side air vent. The second air vent 12 is located on the bottom surface of the housing 10, serving as a bottom air vent. The heat exchanger 20 is disposed inside the housing 10. Optionally, the heat exchanger 20 is disposed corresponding to the side air vent. The volute 30 is disposed inside the housing 10 and is rotatable relative to the housing 10. The volute 30 has an air outlet 31, which faces different positions as the volute 30 rotates. Within the rotatable range of the volute 30, a first position and a second position are provided. Figure 1 As shown, when the volute 30 rotates to the first position, the air outlet 31 of the volute 30 faces the first air outlet 11, thus forming a side air outlet. Figure 4 As shown, when the volute 30 rotates to the second position, the air outlet 31 of the volute 30 faces the second air outlet 12, thus forming a downward air outlet.

[0044] The second air vent 12 has a first edge 121 and a second edge 122. The first edge 121 is closer to the first air vent 11 than the second edge 122. That is, the first edge 121 is the left edge of the second air vent 12, and the second edge 122 is the right edge of the second air vent 12.

[0045] The sealing baffle 40 is rotatably connected to the outer wall of the volute 30. Optionally, the rotatable connection position between the sealing baffle 40 and the volute 30 is located below the air outlet 31 of the volute 30. When the indoor unit of the air conditioner does not switch the air outlet direction, the sealing baffle 40 is in the open state. The bottom of the sealing baffle 40 abuts against the first edge 121 or the second edge 122 to form a seal and prevent air leakage. When the indoor unit of the air conditioner switches the air outlet direction, the sealing baffle 40 is controlled to rotate towards the side that is in contact with the volute 30 so that it can retract. After the sealing baffle 40 is retracted, the volute 30 is controlled to rotate. After the volute 30 is rotated to the target position, the sealing baffle 40 is controlled to open again.

[0046] Optionally, the sealing baffle 40 is an arc-shaped plate, and the curvature matches the curvature of the outer wall of the volute 30. This allows the sealing baffle 40 to fit as close as possible to the outer wall of the volute 30 when it retracts, thereby reducing the space occupied inside the housing 10.

[0047] Optionally, such as Figure 5As shown, the indoor unit can also have multiple volutes 30, each volute 30 being arranged in sequence along the length direction of the housing 10.

[0048] Optionally, in combination with Figure 6 As shown, the indoor unit further comprises a transmission assembly 50 and a driving mechanism 60. The driving mechanism 60 drives the volute 30 to rotate through the transmission assembly 50.

[0049] Optionally, the transmission assembly 50 comprises a partition plate 51 and two transmission plates 52. The length direction of the partition plate 51 is arranged along the length direction of the volute 30, and the partition plate 51 is connected with the volute 30. The two transmission plates 52 are arranged on the two sides of the volute 30 respectively. The two sides of the partition plate 51 are connected with the two transmission plates 52 respectively, so that the two transmission plates 52 and the partition plate 51 form an integral whole, and the transmission assembly 50 as a whole is connected with the volute 30. The partition plate 51 is provided with a mounting hole. The air outlet 31 of the volute 30 is clamped in the mounting hole.

[0050] Any one of the transmission plates 52 is provided with the driving mechanism 60. The driving mechanism 60 drives the corresponding transmission plate 52 to rotate, the transmission plate 52 drives the partition plate 51 to rotate, and the partition plate 51 drives the volute 30 to rotate. Thus, the rotation of the volute 30 is controlled. Optionally, the driving mechanism 60 comprises a first motor 61 and a gear assembly 62. The gear assembly 62 is connected to the transmission plate 52, and the first motor 61 is connected with the gear assembly 62. The first motor 61 drives the gear assembly 62 to rotate, and the gear assembly 62 drives the transmission plate 52 to rotate, thereby driving the partition plate 51 to rotate. The partition plate 51 drives the volute 30 to rotate, so that the rotation of the volute 30 is controlled. Optionally, the gear assembly 62 comprises a first gear 621 and a second gear 622. The first motor 61 drives the first gear 621 to rotate. The first gear 621 is engaged with the second gear 622. The second gear 622 is connected with the transmission plate 52.

[0051] Optionally, the driving mechanism 60 is two. The two driving mechanisms 60 are connected with the two transmission plates 52 respectively and are driven synchronously. This ensures that the driving force received by the partition plate 51 is more balanced, thereby facilitating the stable rotation of the volute 30.

[0052] Optionally, any one end of the sealing baffle 40 is provided with a second motor 70. Through the forward and reverse rotation of the second motor 70, the sealing baffle 40 is driven to open or retract.

[0053] Optionally, both ends of the sealing baffle 40 are provided with the second motor 70, and the two second motors 70 synchronously drive the two ends of the sealing baffle 40 to ensure the stability of the rotation of the sealing baffle 40.

[0054] Optionally, in combination with Figure 7 and Figure 8As shown, the shell 10 includes a first side plate 13, a second side plate 15 and a bottom plate 14, the first side plate 13 and the second side plate 15 are perpendicular to the bottom plate 14, and the first side plate 13 and the second side plate 15 are oppositely and parallel arranged. The first side plate 13 is provided with a first air inlet 11, and the bottom plate 14 is provided with a second air inlet 12. The indoor unit further comprises a filter assembly 80. The filter assembly 80 is located in the shell 10.

[0055] The filter assembly 80 comprises a frame assembly 81, a filter screen 82 and a transmission mechanism.

[0056] In combination Figure 9 As shown, the frame assembly 81 comprises a first frame 811 and a second frame 812, and the filter screen 82 slides in the limited space enclosed by the first frame 811 and the second frame 812. The first frame 811 is fixed inside the shell 10 and used for bearing the filter screen 82. The filter screen 82 is a flexible filter screen 82, and the limited space in the frame assembly 81 provides a limited movement track for the sliding of the filter screen 82. In this way, the problem of layering or jamming of the flexible filter screen 82 during sliding can be avoided.

[0057] In combination Figure 10 As shown, the first frame 811 is provided with a sliding groove 813, the bottom plate 14 is provided with a sliding rail, and the sliding groove 813 can slide along the sliding rail. After the side plate is detached from the shell 10, the frame assembly 81 can be horizontally pulled out of the indoor unit as a whole.

[0058] By utilizing the sliding of the filter screen 82 in the frame assembly 81, the movement of the filter screen 82 between the first air inlet 11 and the second air inlet 12 can be controlled. When the filter screen 82 moves to the position where the first air inlet 11 is located, the first air inlet 11 is shielded and the second air inlet 12 is exposed. When the filter screen 82 moves to the position where the second air inlet 12 is located, the first air inlet 11 is exposed and the second air inlet 12 is shielded. By controlling the movement of the filter screen 82, the filter screen 82 can shield the air inlet and expose the air outlet. Dust and other impurities in the incoming air flow are filtered, impurities are prevented from entering the indoor unit, and the air volume of the air outlet is ensured.

[0059] Optionally, in combination Figure 11 and Figure 12 As shown, the filter screen 82 comprises a guide rail 821, the guide rail 821 comprises a protruding tooth 822, and the transmission mechanism is provided with a gear tooth 831 which is engaged with the protruding tooth 822 for transmission. The filter screen 82 comprises a mesh and a filter sheet. The mesh comprises the guide rail 821, and the filter sheet is located in the mesh of the mesh. The filter sheet is used for filtering impurities in the incoming air flow; the guide rail 821 comprises a plurality of protruding teeth 822, and the plurality of protruding teeth 822 are arranged on the mesh at intervals, so that the filter screen 82 moves back and forth along the direction of the guide rail 821. By moving the filter screen 82, the first air inlet 11 or the second air inlet 12 is adaptively shielded.

[0060] Optionally, the transmission mechanism comprises a rotating shaft 83 and a driving device 84. The rotating shaft 83 comprises a plurality of gear teeth 831 and a shaft cylinder 832 fixed between adjacent gear teeth 831; the driving device 84 is used to drive the rotating shaft 83 to rotate axially; wherein the plurality of guide rails 821 are arranged in parallel with each other and are engaged with the gear teeth 831 one by one.

[0061] Specifically, both ends of the rotating shaft 83 are provided with gear teeth 831, and one or more gear teeth 831 are arranged in the middle of the rotating shaft 83. The gear teeth 831 comprise a wheel-shaped tooth portion 833 and a connecting portion located on both sides of the wheel-shaped tooth portion 833 and integrally formed with the gear teeth 831. The connecting portion is provided with a buckle, and the inner wall of the shaft cylinder 832 is provided with a buckle. The connecting portion is limitedly clamped in the shaft cylinder 832, so that the gear teeth 831 and the shaft cylinder 832 are fixedly connected to avoid generating rotational friction between the gear teeth 831 and the shaft cylinder 832. The rotating shaft 83 is located at a fixed position in the shell 10, and the rotating shaft 83 rotates to drive the wheel-shaped tooth portion 833 to rotate. Compared with the traditional filter screen assembly, the filter screen 82 and the indoor unit of the present disclosure can move the filter screen 82 without the need for a guide mechanism, which not only saves the internal space of the indoor unit, but also meets the filtering and cleaning needs of the reversible air supply indoor unit.

[0062] Optionally, a first transverse air guide plate is arranged at the first air outlet 11. A second transverse air guide plate is arranged at the second air outlet 12. The angles of the first transverse air guide plate and the second transverse air guide plate can be adjusted to realize air swinging or air supply in a specific direction on the basis of the air outlet direction of the first air outlet 11 or the air outlet direction of the second air outlet 12.

[0063] In combination Figure 13 As shown, the embodiment of the present disclosure provides a method for controlling an air conditioner, comprising:

[0064] S1301, the air conditioner determines a target air outlet direction and a current air outlet direction.

[0065] S1302, the air conditioner determines a target position of the volute according to the target air outlet direction and the current air outlet direction.

[0066] S1303, the air conditioner controls the volute and the sealing baffle to switch positions according to the target position of the volute, so that air is blown out from the first air outlet or the second air outlet.

[0067] S1304, the air conditioner controls the filter screen to move according to the target position of the volute.

[0068] The air conditioner can determine the current air outlet direction according to the current operating state, or analyze the air direction instruction sent by the user last time to determine the current air outlet direction. The user can send the air direction instruction to the air conditioner through a remote controller or a mobile device. The mobile device may, for example, include a mobile phone, a smart home device, a wearable device, a smart mobile device, a virtual reality device, or any combination thereof, wherein the wearable device may, for example, include a smart watch, a smart bracelet, a pedometer, or the like.

[0069] After receiving the instruction sent by the user this time, the air conditioner analyzes the instruction to determine the target air outlet direction of the air conditioner. The target air outlet direction is compared with the current air outlet direction to determine the target position of the volute. If the target air outlet direction is consistent with the current air outlet direction, the target position of the volute is the current position, that is, the position of the volute is controlled to remain unchanged. At this time, the state of the filter screen at the first air outlet and the second air outlet remains unchanged. If the target air outlet direction is inconsistent with the current air outlet direction, the target position of the volute is further determined. Then, the volute and the sealing baffle are controlled to rotate according to the target position of the volute. The volute can reciprocate between the first position and the second position. The target position of the volute is the first position or the second position. After the volute rotates to the target position, the air outlet of the air conditioner blows out from the first air outlet or the second air outlet. Based on the target position of the volute, the sealing baffle is adaptively controlled to rotate to reduce air leakage while the air conditioner is blowing air. According to the target position of the volute, the filter screen is controlled to move to different positions to filter dust and other impurities in the air.

[0070] The movement of the filter screen can be performed after the positions of the volute and the sealing baffle are switched, or can be performed synchronously.

[0071] In the embodiments of the present disclosure, the shell is provided with a first air outlet and a second air outlet with different air outlet directions. The shell is provided with a volute that can reciprocate between a first position and a second position. Based on the target air outlet direction and the current air outlet direction, the target position of the volute is determined. The volute is controlled to rotate to the target position to realize air outlet of the air conditioner from the first air outlet or the second air outlet. The rotation of the volute can change the air outlet direction. The air outlet of the volute can smoothly pass through the corresponding air outlet without changing the flow path. Moreover, based on the target position of the volute, the sealing baffle is adaptively controlled to rotate to reduce air leakage. In this way, the stability and uniformity of the air flow are improved to achieve the purpose of improving the air supply effect. At the same time, based on the target position of the volute, the position of the filter screen is controlled to realize effective filtering of air while changing the air direction.

[0072] Optionally, in combination with Figure 14 As shown in the drawings, the embodiments of the present disclosure provide another method for controlling an air conditioner, comprising:

[0073] S1301, the air conditioner determines a target air outlet direction and a current air outlet direction.

[0074] S1312, the air conditioner determines a switching condition of the air direction according to the target air outlet direction and the current air outlet direction.

[0075] S1322, the air conditioner determines a target position of the volute according to the switching condition of the air direction.

[0076] S1303, the air conditioner controls the volute and the sealing baffle to switch positions according to the target position of the volute, so that air is blown out from the first air outlet or the second air outlet.

[0077] S1304, the air conditioner controls the filter screen to move according to the target position of the volute.

[0078] After the target air outlet direction and the current air outlet direction are determined, the target air outlet direction and the current air outlet direction are compared. If the target air outlet direction and the current air outlet direction are consistent, it is determined that the air direction is not switched, and the volute remains in the current position. If the target air outlet direction and the current air outlet direction are inconsistent, it is determined that the air direction is switched. Since the air conditioner has a first air outlet and a second air outlet, the switching of the air direction is specifically switching between the air outlet direction of the first air outlet and the air outlet direction of the second air outlet. According to the specific switching direction, the target position of the volute is determined. In this way, the air outlet of the volute at the target position can meet the demand for switching of the air direction, i.e. meet the target air outlet direction, thereby meeting the demand of the user for the air direction. It should be noted that the specific implementation process of steps S1301, S1303 and S1304 can be referred to the above embodiment, which will not be described here.

[0079] Optionally, S1312, the air conditioner determines a switching condition of the air direction according to the target air outlet direction and the current air outlet direction, including:

[0080] In the case where the target air outlet direction and the current air outlet direction are consistent, the air conditioner determines that the air direction is not switched.

[0081] In the case where the target air outlet direction is downward air outlet and the current air outlet direction of the air conditioner is side air outlet, it is determined that the air direction is switched from side air outlet to downward air outlet.

[0082] In the case where the target air outlet direction is side air outlet and the current air outlet direction of the air conditioner is downward air outlet, it is determined that the air direction is switched from downward air outlet to side air outlet.

[0083] When the volute rotates to the first position, the air outlet of the volute corresponds to the first air outlet, i.e., corresponds to the side air outlet, at this time, the air outlet of the air conditioner is side air outlet. When the volute rotates to the second position, the air outlet of the volute corresponds to the second air outlet, i.e., corresponds to the lower air outlet, at this time, the air outlet of the air conditioner is lower air outlet. If the target air outlet direction and the current air outlet direction are consistent, it is determined that the air direction is not switched. If the target air outlet direction and the current air outlet direction are inconsistent, it is further determined that the specific direction of the target air outlet direction and the current air outlet direction. If the target air outlet direction is lower air outlet, and the current air outlet direction is side air outlet, it is determined that the switching condition of the air direction is that the side air outlet is switched to the lower air outlet. If the target air outlet direction is side air outlet, and the current air outlet direction is lower air outlet, it is determined that the switching condition of the air direction is that the lower air outlet is switched to the side air outlet. In this way, based on the comparison of the target air outlet direction and the current air outlet direction, it is determined whether the air direction needs to be switched, and when it needs to be switched, the specific switching direction is determined. In order to accurately control the rotation of the volute.

[0084] Optionally, S1322, the air conditioner determines the target position of the volute according to the switching condition of the air direction, comprising:

[0085] In the case of switching from side air outlet to lower air outlet, the air conditioner determines that the target position of the volute is the second position.

[0086] In the case of switching from lower air outlet to side air outlet, the air conditioner determines that the target position of the volute is the first position.

[0087] As described above, when the volute is in the first position, it corresponds to the side air outlet of the air conditioner. When the volute is in the second position, it corresponds to the lower air outlet of the air conditioner. Since the air outlets of the air conditioner are side air outlet and lower air outlet respectively, the air direction is also switched between side air outlet and lower air outlet. If the air direction is switched from side air outlet to lower air outlet, it is determined that the target position of the volute is the second position. If the air direction is switched from lower air outlet to side air outlet, it is determined that the target position of the volute is the first position. In this way, the target position of the volute corresponds to the target air outlet direction, so as to realize the normal air supply of the air conditioner.

[0088] Optionally, in combination with Figure 15 As shown in the figure, the embodiment of the present disclosure provides another method for controlling an air conditioner, comprising:

[0089] S1301, the air conditioner determines the target air outlet direction and the current air outlet direction.

[0090] S1312, the air conditioner determines the switching condition of the air direction according to the target air outlet direction and the current air outlet direction.

[0091] S1322, the air conditioner determines the target position of the volute according to the switching condition of the air direction.

[0092] S1313, the air conditioner controls the sealing baffle to rotate to the direction of abutting the volute in the case that the target position of the volute is different from the current position.

[0093] S1323, the air conditioner controls the volute to rotate to the target position of the volute.

[0094] S1333, the air conditioner controls the sealing baffle to rotate to the target position of the sealing baffle.

[0095] S1304, the air conditioner controls the filter screen to move according to the target position of the volute.

[0096] As described above, the target position of the volute is the first position or the second position. The first position and the second position correspond to the side air outlet and the lower air outlet respectively. If the target air outlet direction is different from the current air outlet direction, the target position of the volute is also different from the current position. The sealing baffle can rotate relative to the volute. When the sealing baffle rotates away from the volute, the sealing baffle is in the open state. When the sealing baffle rotates to the position of abutting the outer wall of the volute, the sealing baffle is in the retracted state. When the volute is fixed at the target position to blow air, the sealing baffle is in the open state to seal the second air outlet and reduce air leakage. When the volute rotates, the sealing baffle needs to be retracted to avoid hindering the rotation of the volute. Therefore, when controlling the rotation of the volute and the sealing baffle, the sealing baffle is controlled to retract first, and then the volute is controlled to rotate. After the volute rotates to the target position, the sealing baffle is controlled to open to the target position of the sealing baffle. In this way, not only the switching of the air outlet direction is realized by controlling the rotation of the volute, but also the rotation of the sealing baffle hinders the rotation of the volute is avoided by controlling the timing of the rotation of the sealing baffle and the volute. Thus, the effective switching of the air outlet direction is ensured. It should be noted that the specific implementation process of steps S1301, S1312, S1322 and S1304 can be referred to the above embodiments, which will not be described here.

[0097] Optionally, the target position of the sealing baffle has two positions. In the case of determining the switching of the air direction, when the target position of the volute is the first position, the target position of the sealing baffle is the third position. When the sealing baffle is located at the third position, the bottom of the sealing baffle abuts the first edge of the second air outlet. At this time, the sealing baffle separates the first air outlet and the second air outlet, and also separates the air outlet of the volute and the second air outlet, preventing the air outlet of the volute from leaking out of the second air outlet. In order to ensure the air blowing effect of the air conditioner.

[0098] When the target position of the volute is the second position, the target position of the sealing baffle is the fourth position. When the sealing baffle is located at the fourth position, the side surface of the sealing baffle abuts against the second edge. At this time, the left side of the air outlet of the volute abuts against the first edge. After cooperating with the sealing baffle, the air outlet of the volute can send out air as much as possible from the second air outlet, and the air flow flowing back into the shell is reduced. Thus, the air supply effect of the air conditioner is ensured.

[0099] Optionally, S1304, the air conditioner controls the filter screen to move according to the target position of the volute, including:

[0100] When the target position of the volute is the first position, the air conditioner controls the filter screen to move to a position of exposing the first air outlet and shielding the second air outlet.

[0101] When the target position of the volute is the second position, the air conditioner controls the filter screen to move to a position of shielding the first air outlet and exposing the second air outlet.

[0102] As known from the above, the filter screen has a certain flexibility. Therefore, the filter screen can be rolled up. In this way, the filter screen can be controlled to move between the first air outlet and the second air outlet. If the target position of the volute is the first position, the first air outlet serves as an air outlet, and the second air outlet serves as an air inlet. The rotation shaft of the filter assembly is controlled to rotate clockwise, so that the rotation shaft drives the filter screen to move downward. The filter screen exposes the first air outlet while shielding the second air outlet. If the target position of the volute is the second position, the second air outlet serves as an air outlet, and the first air outlet serves as an air inlet. The rotation shaft of the filter assembly is controlled to rotate counterclockwise, so that the rotation shaft drives the filter screen to move upward. The filter screen shields the first air outlet while exposing the second air outlet. Optionally, the rotation shaft is driven to rotate by a driving device. In this way, the filter screen is controlled to shield the air inlet, so that the dust entering the indoor unit is reduced. The filter screen is controlled to expose the air outlet, so that the dust on the filter screen is prevented from being blown into the indoor unit, and the air outlet is ensured to have a certain air volume.

[0103] Optionally, S1323, the air conditioner controls the volute to rotate to the target position of the volute, including:

[0104] The air conditioner determines the target rotation direction of the volute.

[0105] The air conditioner controls the volute to rotate to the target rotation direction of the volute by a second angle.

[0106] According to the target position of the volute, the target rotating direction of the volute is determined. When the target position of the volute is the first position, the target rotating direction of the volute is determined to be upward rotation, i.e. clockwise rotation. When the target position of the volute is the second position, the target rotating direction of the volute is determined to be downward rotation, i.e. counterclockwise rotation. After the target rotating direction of the volute is determined, the volute is controlled to rotate a second angle β in the determined target rotating direction. Since the first position and the second position are fixed, no matter whether the volute rotates from the first position to the second position or from the second position to the first position, the rotating angle of the volute is the first angle. In this way, the target rotating direction of the volute is determined first, so as to minimize the distance (or angle) of the volute rotation as much as possible, so as to make the volute rotate to the appropriate air outlet position quickly. Then the volute is controlled to rotate a second angle, so as to accurately control the stop position of the volute rotation, and reduce the problem of the volute not rotating to the position or over-rotation.

[0107] Optionally, in S1333, the air conditioner controls the sealing baffle to rotate to the target position of the sealing baffle, including:

[0108] The air conditioner determines the target rotating direction of the sealing baffle.

[0109] In the case that the target position of the sealing baffle is the third position, the air conditioner controls the sealing baffle to rotate a first angle in the target rotating direction of the sealing baffle.

[0110] In the case that the target position of the sealing baffle is the fourth position, the air conditioner controls the sealing baffle to rotate a third angle in the target rotating direction of the sealing baffle; wherein the second angle is greater than the first angle, and the first angle is greater than the third angle.

[0111] The target position of the volute and the target position of the sealing baffle have correspondence. Therefore, the target rotating position of the sealing baffle can be determined according to the target position of the volute. The sealing baffle needs to be opened to rotate to the target position.

[0112] If the target position of the volute is the first position, the target position of the sealing baffle is the third position. The target rotating direction thereof is left rotation, i.e. clockwise rotation. Then the sealing baffle is controlled to rotate a first angle α clockwise. If the target position of the volute is the second position, the target position of the sealing baffle is the fourth position. The target rotating direction thereof is downward rotation, i.e. clockwise rotation. Then the sealing baffle is controlled to rotate a third angle γ clockwise. In this way, the target rotating direction of the sealing baffle is determined first, so as to make the sealing baffle be in the opened state, and make the sealing baffle rotate in the rotating direction, so as to enable the sealing baffle to seal the second air outlet. Then the volute is controlled to rotate a suitable angle, so as to accurately control the stop position of the sealing baffle rotation, avoid the problem of the sealing baffle not rotating to the position, and avoid the problem of air leakage, so as to ensure the stability of air supply.

[0113] Since the first air outlet and the second air outlet are located on different sides of the shell, when the air outlet direction is switched, the second angle β of the rotation of the volute is also large. When the volute is rotated to the first position, the rotation point of the sealing baffle is far away from the second air outlet. Therefore, in order to seal the second air outlet, the sealing baffle needs to rotate a large first angle a, but not more than the second angle β. When the volute is rotated to the second position, the rotation point of the sealing baffle is close to the second air outlet. Therefore, the sealing baffle only needs to rotate a third angle γ to seal the second air outlet. Therefore, β > a > γ. Optionally, a ∈ [40°, 60°], β ∈ [69°, 89°], and γ ∈ [5°, 25°]. The specific values of a, β, and γ can be selected according to actual needs.

[0114] Optionally, in combination with Figure 16 As shown in FIG. 1, the disclosure provides another method for controlling an air conditioner, comprising:

[0115] S1301, the air conditioner determines a target air outlet direction and a current air outlet direction.

[0116] S1302, the air conditioner determines a target position of the volute according to the target air outlet direction and the current air outlet direction.

[0117] S1303, the air conditioner controls the volute and the sealing baffle to switch positions according to the target position of the volute, so that air is blown out from the first air outlet or the second air outlet.

[0118] S1304, the air conditioner controls the filter screen to move according to the target position of the volute.

[0119] S1305, the air conditioner determines a target air outlet according to the target air outlet direction.

[0120] S1306, the air conditioner controls the angle of each horizontal air deflector according to the target air outlet.

[0121] Based on the determined target air outlet direction, a target air outlet is determined. The target air outlet is an air outlet, and a non-target air outlet is an air inlet. If the target air outlet direction is side air outlet, the target air outlet is the first air outlet (side air outlet). If the target air outlet direction is down air outlet, the target air outlet is the second air outlet (down air outlet). When the air conditioner is running, the first and second lateral air deflectors are both opened to the maximum angle to ensure maximum air inlet and maximum air outlet. Alternatively, the angle of the lateral air deflector at the target air outlet can be controlled according to the user's air supply requirements to achieve swing air supply or air supply in a specific direction. However, in principle, the lateral air deflector at the non-target air outlet is always controlled to maintain the maximum angle to ensure the maximum air inlet. Alternatively, the maximum angle of the first and second lateral air deflectors is the angle of the lateral air deflector when the lateral air deflector is parallel to the air inlet direction. It should be noted that the specific implementation process of steps S1301, S1312, S1322 and S1304 can be referred to the above embodiments, which will not be repeated here.

[0122] The process of controlling the volute, the sealing baffle and the filter screen will be described below:

[0123] Case one: as shown in Figure 1 , the current air outlet direction is side air outlet, and the target air outlet direction is down air outlet. At this time, the volute is located at the first position; the sealing baffle is located at the third position; the filter screen exposes the first air outlet and blocks the second air outlet. The target position of the volute is the second position; the target position of the sealing baffle is the fourth position.

[0124] As shown in Figure 1 and Figure 2 , first control the sealing baffle to rotate counterclockwise by a first angle a, so that the sealing baffle is attached to the outer wall of the volute. Then as shown in Figure 2 and Figure 3 , control the volute to rotate counterclockwise by a second angle β, so that the volute is rotated to the second position. At this time, the air outlet of the volute corresponds to the down air outlet, and the left side of the air outlet of the volute abuts against the first edge of the down air outlet. Then as shown in Figure 3 and Figure 4 , control the sealing baffle to rotate clockwise by a third angle γ, so that the side surface of the sealing baffle abuts against the second edge of the down air outlet. And control the filter screen to block the first air outlet and expose the second air outlet.

[0125] Case two: as shown in Figure 4 , the current air outlet direction is down air outlet, and the target air outlet direction is side air outlet. At this time, the volute is located at the second position; the sealing baffle is located at the fourth position; the filter screen blocks the first air outlet and exposes the second air outlet. The target position of the volute is the first position; the target position of the sealing baffle is the third position.

[0126] As shown in Figure 4 and Figure 3As shown, the sealing baffle is first controlled to rotate counterclockwise by a third angle γ, so that the sealing baffle is attached to the outer wall of the volute. Then, as shown in Figure 3 and Figure 2 As shown, the volute is controlled to rotate clockwise by a second angle β, so that the volute is rotated to the first position. At this time, the air outlet of the volute corresponds to the side air outlet. Then, as shown in Figure 2 and Figure 1 As shown, the sealing baffle is controlled to rotate clockwise by a first angle α, so that the bottom of the sealing baffle abuts against the first edge of the lower air outlet. The filter screen is controlled to expose the first air outlet while shielding the second air outlet.

[0127] In combination with Figure 17 The embodiment of the present disclosure provides a device for controlling an air conditioner, which comprises a first determining module 171, a second determining module 172 and a control module 173.

The rotation of the volute can change the air outlet direction. The air outlet of the volute can smoothly pass through the corresponding air outlet without changing the flow path. Moreover, based on the target position of the volute, the sealing baffle is adaptively rotated, so that the air leakage phenomenon is reduced. In this way, the stability and uniformity of the air outlet airflow are improved, so as to achieve the purpose of improving the air supply effect. At the same time, based on the target position of the volute, the position of the filter screen is controlled, so that the air is effectively filtered while the air direction is changed.
