[0002] Traditional floor-standing air conditioners typically use a single fan to drive airflow and have only one air outlet. The direction of airflow is changed by the oscillation of blades within the air duct. This single airflow pattern cannot meet the diverse airflow needs of users. Furthermore, since cold air tends to flow downwards and warm air tends to flow upwards indoors, in cooling or heating mode, hot air tends to concentrate in the upper part of the room, while cold air tends to concentrate in the lower part.

[0085] Traditional floor-standing air conditioners typically use a single fan to drive airflow and have only one air outlet. The direction of airflow is changed by the oscillation of blades within the air duct. This single airflow pattern cannot meet the diverse airflow needs of users. Furthermore, since cold air tends to flow downwards and warm air tends to flow upwards indoors, in cooling or heating mode, hot air tends to concentrate in the upper part of the room, while cold air tends to concentrate in the lower part. This results in uneven indoor temperature distribution and consequently, poor user comfort.

[0086] To address this, this invention provides an air conditioner 100 comprising multiple first air outlets 2 with corresponding air supply impellers 102 supplying air to them, and a movable panel 11 that can switch between multiple different states. During the switching of states of the movable panel 11, the air conditioner 100 can switch to multiple different air outlet modes to meet various different user air needs. In cooling or heating mode, the movable panel 11 can concentrate the airflow to the upper part of the air conditioner 100 or the lower part of the air conditioner 100, solving the problem of uneven indoor temperature distribution and improving user comfort during use.

[0087] The following is for reference. Figures 1-28 An air conditioner 100 according to an embodiment of the present invention is described.

[0088] like Figures 1-19 As shown in the figure, this application embodiment provides an air conditioner 100, which includes: a housing 1, a plurality of air supply impellers 102 and a movable panel 11.

[0089] The front side of the housing 1 is provided with multiple first air outlets 2, which are arranged sequentially along the height direction. Multiple air supply impellers 102 are also arranged sequentially along the height direction. Each air supply impeller 102 can send air out through its corresponding first air outlet 2. By controlling whether the multiple first air outlets 2 located at different vertical positions are emitting air and controlling the air outlet direction of different first air outlets 2, the air conditioner 100 can form a variety of different air outlet modes, enriching the air outlet forms of the air conditioner 100, better realizing the various functions of the air conditioner 100, and giving users a better experience.

[0090] Each air supply impeller 102 is provided with at least one first air outlet 2, which ensures that the air volume of each first air outlet 2 is uniform. Since each first air outlet 2 is supplied with air by the corresponding air supply impeller 102, the airflow loss is small and the airflow at the air outlet is strong enough to ensure the air supply distance of the air conditioner 100.

[0091] The front side of the housing 1 is also provided with a movable panel 11. The movable panel 11 is movably disposed on the housing 1. By controlling the movable panel 11 to move to different positions, the air conditioner 100 can be controlled to switch between a variety of different air outlet modes.

[0092] Specifically, the movable panel 11 is movable between at least a first state and a second state. In the first state, the movable panel 11 closes at least part of the first air outlet 2. When the closed portion of the first air outlet 2 is entirely located at the bottom of the air conditioner 100 and the remaining open portion is entirely located at the top of the air conditioner 100, the corresponding air outlet mode can be applied to the cooling function of the air conditioner 100. When the closed portion of the first air outlet 2 is entirely located at the top of the air conditioner 100 and the remaining open portion is entirely located at the bottom of the air conditioner 100, the corresponding air outlet mode can be applied to the heating function of the air conditioner 100. When the closed portion of the first air outlet 2 is located in the middle of the air conditioner 100 and the remaining open portion is partially located at the top and partially at the bottom, the corresponding air outlet mode can be applied to the top and bottom air outlet mode of the air conditioner 100.

[0093] In some embodiments, the movable panel 11 is in a first state at least when it is moved to a first position and when it is moved to a second position. When the movable panel 11 is moved to the first position, the closed portion of the first air outlet 2 is entirely located at the lower part of the air conditioner 100, while the open portion of the first air outlet 2 is entirely located at the upper part of the air conditioner 100. When the movable panel 11 is moved to the second position, the closed portion of the first air outlet 2 is entirely located at the upper part of the air conditioner 100, while the open portion of the first air outlet 2 is entirely located at the lower part of the air conditioner 100.

[0094] When the air conditioner is in cooling mode, cold air tends to flow downwards indoors. To ensure uniform temperature distribution within the room, the movable panel 11 moves to its first position, discharging cold air outwards through the first air outlet 2 located on the upper part of the air conditioner 100. This allows cold air to circulate in the upper layers of the room, improving the cooling effect of the air conditioner 100 and solving the problem of uneven indoor temperature distribution.

[0095] When the air conditioner is in heating mode, the high-temperature airflow has the characteristic of upward flow in the room. In order to ensure the uniformity of indoor temperature distribution, the movable panel 11 moves to the second position and sends cold air out through the first air outlet 2 located in the lower part of the air conditioner 100, so that the temperature of the lower layer of the room can also be improved, thereby improving the heating effect of the air conditioner 100 and ensuring the uniform distribution of indoor temperature.

[0096] When the movable panel 11 is moved to the first state, it fits against the front of the housing 1 to close at least part of the first air outlet 2 located on the front of the housing 1. When the movable panel 11 is moved to the second state, at least part of the movable panel 11 is located on the front of the housing 1 and spaced apart from the housing 1. An air guide space 8 is defined between the movable panel 11 and the housing 1. The air guide space 8 has an air outlet area 82, which surrounds the movable panel 11. At least part of the first air outlet 2 sends air into the air guide space 8. Thus, the airflow blown out from the first air outlet 2 first enters the air guide space 8 defined by the movable panel 11 and the front of the housing 1, and is blown outward through the air outlet area 82 under the guidance of the air guide space 8. Since the air outlet area 82 surrounds the movable panel 11, the air conditioner 100 can blow air in all directions, and the blown air will not blow directly on the user due to the obstruction of the movable panel 11, improving user comfort. This air outlet method can be applied to the all-area air outlet mode of the air conditioner 100.

[0097] According to the embodiment of this application, the air conditioner 100 has a variety of different air outlet modes, which can meet the different air needs of users, solve the problem of uneven indoor temperature distribution, and improve the comfort of users during use.

[0098] like Figure 4 , Figures 16-19 As shown, in the second state, the movable panel 11 is spaced apart from the housing 1 so that the air guiding space 8 defined between the movable panel 11 and the housing 1 can be at a certain angle to the first air outlet 2, so that the air from the first air outlet 2 can first enter the air guiding space 8 and then flow into the room under the guidance of the air guiding space 8.

[0099] Among them, reference Figure 4 An air outlet area 82 is defined between the outer periphery of the movable panel 11 and the housing 1. Thus, airflow within the guided air space 8 can flow into the room through the air outlet area 82 defined by the gap between the movable panel 11 and the housing 1. Since the edges of the movable panel 11 in each direction can be spaced apart from the housing 1 to define air supply areas, air can be discharged outwards in all directions, allowing the user to achieve a full-area air outlet mode for the air conditioner 100.

[0100] In some embodiments, the air outlet area 82 may further include a plurality of air outlet holes provided through the movable panel 11, through which airflow in the guide air space 8 can flow into the room. This allows a portion of the airflow from the air conditioner 100 to pass through the obstruction of the movable panel 11 and blow forward in this air outlet mode.

[0101] Reference Figure 4 , Figure 16 and Figure 19 The movable panel 11 is connected to the housing 1 via the connecting rod 1122 assembly 112 so that it can swing relative to the housing 1. By swinging the movable panel 11, the movable panel 11 can swing to the first position, the second position, and the third position between the second position and the second position.

[0102] like Figure 20 As shown, the linkage 1122 assembly 112 includes a linkage 1122 and a second drive motor 1121. The motor shaft of the second drive motor 1121 is fixedly connected to one end of the linkage 1122, and the other end of the linkage 1122 is rotatably connected to the movable panel 11.

[0103] Combination Figures 1-19 In the illustrated embodiment, the position and state changes of the movable panel 11 are switched by controlling its swing. This allows for control of the movable panel 11's position both vertically and horizontally. When the movable panel 11 swings to the first or second position, the housing 1 is in contact with the movable panel 11, limiting its movement. When it swings to a position between the first and second positions, the movable panel 11 also creates a space between itself and the housing 1, defining an airflow space 8.

[0104] Furthermore, since the movable panel 11 remains parallel to the front surface of the housing 1 during its movement, the relative position between the movable panel 11 and the housing 1 can be switched by swinging, ensuring the posture of the movable panel 11 and enabling it to always be set parallel to the front surface of the housing 1.

[0105] like Figure 5 , Figure 9 , Figure 12 , Figure 15 and Figure 19 As shown, the plurality of air supply impellers 102 include a top air supply impeller 1021, a middle air supply impeller 101 and a bottom air supply impeller 102. The top air supply impeller 102 can supply air to the air outlet located at the top, the bottom air supply impeller 102 can supply air to the air outlet located at the bottom, and the middle impeller located in the middle can supply air to some of the air outlets located in the middle.

[0106] In the first state, the movable panel 11 is used to at least close the first air outlet 2 corresponding to the intermediate air supply impeller 101. The first air outlet 2 corresponding to the intermediate air supply impeller 101 is located between the upper air outlet 21 corresponding to the top air supply impeller 1021 and the lower air outlet 22 corresponding to the bottom air supply impeller 102. Thus, when the movable panel 11 is in the first state, the first air outlet 2 corresponding to the intermediate air supply impeller 101 does not produce air. In the second state, the movable panel 11 is located in front of the first air outlet 2 corresponding to the intermediate air supply impeller 101. That is, the movable panel 11 can open the first air outlet 2 corresponding to the intermediate air supply impeller 101. The first air outlet 2 corresponding to the intermediate air supply impeller 101 blows air outward and into the air guide space 8 defined between the movable panel 11 and the housing 1. Under the guidance of the movable panel 11, the air is blown outward through the air outlet area 82 defined between the outer periphery of the movable panel 11 and the housing 1.

[0107] In some embodiments, the movable panel 11 is in a first state when it swings to a first position or to a second position. When the movable panel 11 swings to the first position, the movable panel 11 closes the first air outlet 2 corresponding to the middle air supply impeller 101 and the first air outlet 2 corresponding to the bottom air supply impeller 102, and opens the first air outlet 2 corresponding to the top air supply impeller 1021.

[0108] When the movable panel 11 swings to the second position, the movable panel 11 swings to close the first air outlet 2 corresponding to the middle air supply impeller 101 and the first air outlet 2 corresponding to the top air supply impeller 1021, and the first air outlet 2 corresponding to the bottom air supply impeller 102 opens.

[0109] Reference Figure 9 , Figure 12 , Figure 15 and Figure 19The housing 1 is provided with a first air duct 3. The air outlet sides of the top air supply impeller 1021 and the bottom air supply impeller 102 are both connected to the first air outlet 2 through the first air duct 3. At least one first air duct 3 is provided with a first air guide 12. When the top air supply impeller 1021 supplies air to the first air outlet 2, it needs to be guided by the first air guide 12. The angle between the first air guide 12 and the air supply airflow determines the direction in which the first air guide 12 guides the airflow, and determines the air outlet direction of the first air outlet 2.

[0110] During the process of the bottom air supply impeller 102 supplying air to the first air outlet 2, it needs to be guided by the first air guide 12. The angle between the first air guide 12 and the air supply airflow determines the direction in which the first air guide 12 guides the airflow, and thus determines the air outlet direction of the first air outlet 2.

[0111] In some embodiments, such as Figure 9 , Figure 12 , Figure 15 and Figure 19 As shown, the first air duct 3 includes an upper air duct 31 and a lower air duct 32, the first air guide 12 includes an upper air guide 121 and a lower air guide 122, and the first air outlet 2 includes an upper air outlet 21 and a lower air outlet 22. The top air supply impeller 1021 supplies air to the upper air outlet 21 through the upper air duct 31. The upper air guide 121 is located in the upper air duct 31 and controls the air outlet direction of the upper air outlet 21. The bottom air supply impeller 102 supplies air to the lower air outlet 22 through the lower air duct 32. The lower air guide 122 is located in the lower air duct 32 and controls the air outlet direction of the lower air outlet 22.

[0112] In the second state, the movable panel 11 is located in front of the first air outlet 2 corresponding to the middle air supply impeller 101. The movable panel 11 and the first air outlet 2 corresponding to the middle air supply impeller 101 define an air guiding space 8. The first air outlet 2 corresponding to the top air supply impeller 1021 should blow air diagonally downward so that the airflow can enter the air guiding space 8 first. The air outlet 2 corresponding to the bottom air supply impeller 102 should blow air diagonally upward so that the airflow can enter the air guiding space 8 first.

[0113] The first air guide 12 can be rotated to a position that directs airflow into the air guide space 8. Thus, under the action of the first air guide 12, the first air outlet 2 corresponding to the top air supply impeller 1021 and the first air outlet 2 corresponding to the bottom air supply impeller 102 can both deliver air into the air guide space 8. As a result, the airflow blown out from the first air outlet 2 will first enter the air guide space 8 defined by the movable panel 11 and the front side of the housing 1. Under the guidance of the air guide space 8, the airflow is blown outward through the air outlet area 82. Since the air outlet area 82 is arranged around the movable panel 11, the air conditioner 100 can blow air in all directions, and the blown air will not blow directly on the user due to the obstruction of the movable panel 11, thus improving user comfort. This air outlet method can be applied to the all-area air outlet mode of the air conditioner 100.

[0114] like Figure 16 and Figure 19 As shown, in the second state, a portion of each first air duct 3 is exposed on the movable panel 11, that is, a portion of each first air outlet 2 connected to the first air duct 3 is exposed on the movable panel 11. This causes some airflow to blow directly forward without passing through the air guide space 8 in the second state. Therefore, a first air guide 12 is provided in each first air duct 3 to guide all the airflow passing through the first air duct 3 to the air guide space 8, avoid direct airflow, and ensure the comfort of the user when using the air conditioner 100.

[0115] like Figure 1 and Figure 6 As shown, the air conditioner 100 also includes a switch door 4, which, together with the movable panel 11, closes all the first air outlets 2 when the air conditioner 100 is turned off, ensuring the aesthetics of the air conditioner 100 when it is turned off and preventing foreign objects from the outside environment from entering the interior of the air conditioner 100, thus ensuring the service life of the air conditioner 100.

[0116] Reference Figure 9 , Figure 12 , Figure 15 and Figure 19 The first air guide 12 is located inside the first air duct 3 to avoid the setting of the first air guide 12 affecting the movement of the movable panel 11 and the opening and closing door 4, and to avoid interference between the two.

[0117] At least one first air outlet 2 is provided with a switch door 4 for opening or closing it. When the movable panel 11 is moved to the first state, the movable panel 11 is attached to the front side of the housing 1 to close at least part of the first air outlet 2 located on the front side of the housing 1. The switch door 4 can be used to close the remaining part of the first air outlet 2 located on the front side of the housing 1.

[0118] One of the first air outlets 2 is closed by the switch door 4, and the other first air outlets 2 are closed by the active panel 11 which is in the first state.

[0119] In some embodiments, the first air outlet 2 includes an upper air outlet 21 corresponding to the top air supply impeller 1021, a middle air outlet 23 corresponding to the middle air supply impeller 102, and a lower air outlet 22 corresponding to the bottom air supply impeller 102. When the movable panel 11 is moved to the first state, the movable panel 11 is attached to the front side of the housing 1.

[0120] When the movable panel 11 is moved to the first position in the first state, it covers the front of the lower air outlet 22 and the middle air outlet 23, closing the lower air outlet 22 and the middle air outlet 23. When the movable panel 11 is moved to the second position in the first state, it covers the front of the upper air outlet 21 and the middle air outlet 23, closing the upper air outlet 21 and the middle air outlet 23.

[0121] The switch door 4 can be used to close the upper air outlet 21 or the lower air outlet 22. When the switch door 4 is used to close the upper air outlet 21, the movable panel 11 is in the first position when the air conditioner 100 is turned off. When the switch door 4 is used to close the lower air outlet 22, the movable panel 11 is in the second position when the air conditioner 100 is turned off.

[0122] like Figures 2-5 As shown, the door 4 opens the first air outlet 2 that it had closed when the air conditioner 100 is turned on, so as to avoid the door 4 affecting the movement of the movable panel 11 or the first air guide 12. That is, when the door 4 moves to the position where the first air outlet 2 is open, the movable panel 11 moves.

[0123] Combination Figure 22 and Figure 23 In the embodiment shown, the switch door 4 is movably located inside the front sidewall 103 of the housing 1 to avoid the movement path of the movable panel 11.

[0124] When the air conditioner 100 is turned off and one of the upper air outlet 21 and lower air outlet 22 is closed, the door 4 is flush with the front side wall 103 of the housing 1 to ensure that the front surface of the air conditioner 100 is flat and beautiful when closed, and that external dust does not easily accumulate.

[0125] After the air conditioner 100 is turned on, in order to open the first air outlet 2 while avoiding the movement path of the movable panel 11, the switch door 4 should move away from the movable panel 11 to open the first air outlet 2. When the switch door 4 moves to the open position, it will overlap with the housing 1 of the air conditioner 100. In some embodiments, the switch door 4 moves to the outside of the housing 1 after the air conditioner 100 is turned on. In other embodiments, the switch door 4 moves to the inside of the housing 1 after the air conditioner 100 is turned on. This allows the housing 1 to house the switch door 4, preventing it from being damaged by external forces in the external environment.

[0126] Combination Figures 22-28In the embodiment shown, one of the housing 1 and the switch door 4 is provided with a guide post 41 and the other is provided with a guide groove 17. The guide post 41 and the guide groove 17 are slidably engaged, and the switch door 4 moves under the guidance of the guide groove 17 to ensure the stability of the movement of the switch door 4.

[0127] Among them, reference Figure 22 and Figure 23 The end of the guide groove 17 is provided with a forward-extending guide portion 171. When the guide post 41 is located in the guide portion 171, the switch door 4 closes the corresponding first air outlet 2. The front of the air conditioner 100 is the side of the switch door 4 away from the air supply impeller 102, and the rear of the air conditioner 100 is the side of the switch door 4 facing the air supply impeller 102.

[0128] Specifically, during the process of opening the corresponding first air outlet 2, the switch door 4 first moves backward a certain distance, so that the switch door 4 and the front side wall 103 of the housing 1 change from the same plane to the state where the front side wall 103 of the housing 1 is in front and the switch door 4 is behind, so that the switch door 4 can be subsequently stored inside the housing 1, behind the front side wall 103 of the housing 1.

[0129] In some embodiments, refer to Figure 23 The extension direction of the front guide portion 171 of the guide groove 17 is inclined forward in the direction close to the movable panel 11. Therefore, while driving the switch door 4 to move away from the movable panel 11, the switch door 4 will also move backward under the guidance of the guide groove 17. At the same time as driving the switch door 4 to move closer to the movable panel 11, the switch door 4 will also move from the rear to the front side, which is on the same plane as the front side wall 103 of the housing 1, under the guidance of the front guide portion 171, so as to close the corresponding air outlet while ensuring that the air conditioner 100 has a flat and beautiful appearance.

[0130] like Figures 24-28 As shown, the air conditioner 100 also includes a first driving component 5, which includes a first driving member 51 and a first transmission assembly. The first transmission assembly includes a first moving member 52. The first driving member 51 and the first moving member 52 cooperate to drive the first moving member 52 to reciprocate. The first moving member 52 cooperates with the door 4 through the connecting assembly 53.

[0131] In some embodiments, the first driving member 51 includes a first driving motor disposed on one side of the width direction of the first moving member 52, the first moving member 52 includes a first moving rack, the first moving rack has teeth on the side of its width direction near the first driving member 51, and the first transmission assembly further includes a first gear 54 set, the first gear 54 set is disposed on one side of the width direction of the first moving rack and meshes with the teeth of the first moving rack.

[0132] The first gear set 54 includes a first gear 54, a second gear 55, and a third gear 56. The first gear 54 is fixedly connected to the drive shaft of the first drive motor. The first gear 54 meshes with the second gear 55, the second gear 55 meshes with the third gear 56, and the third gear 56 meshes with the first moving rack. Thus, the first moving rack moves vertically reciprocally under the driving force of the first drive member 51 transmitted by the first gear set 54. The door 4 is connected to the first moving rack through a connecting assembly 53. With the connection of the connecting assembly 53, the door 4 can move away from and / or towards the first moving rack.

[0133] The first drive component 5 also includes a first mounting box 57, which is fixedly connected to the housing 1. In some embodiments, the first mounting box 57 is fixedly disposed on the front side wall 103 of the housing 1.

[0134] The first mounting box 57 includes a first guide rail 58 extending from inside the first mounting box 57 to outside the first mounting box 57. A first movable rack moves under the guidance of the first guide rail 58. The first movable rack is vertically movable and guides the first guide rail 58. A first gear 54 set is rotatably disposed inside the first mounting box 57. A first driving member 51 is fixedly disposed outside the first mounting box 57, and the drive shaft of the first driving member 51 passes through the first mounting box 57 and is fixedly connected to the first gear 54 in the first gear 54 set disposed inside the first mounting box 57.

[0135] The first transmission component in the first driving component 5 can be modified in different ways, such as a transmission component consisting of a lead screw and a nut that achieves transmission through spline transmission, etc., which is not limited here.

[0136] like Figure 22 , Figure 23 and Figure 28 As shown, the connecting component 53 is rotatably engaged with the first moving part 52 and the switch door 4 respectively. Since the switch door 4 and the first moving part 52 are always parallel during the movement, the angle between the connecting component 53 and the switch door 4 increases as the switch door 4 moves away from the first moving part 52. The angle between the connecting component 53 and the plane where the first moving part 52 is located also increases. That is, the connecting component 53 rotates relative to the first moving part 52 and the switch door 4.

[0137] As the door 4 moves toward the first moving member 52, the angle between the connecting component 53 and the door 4 decreases, and the angle between the connecting component 53 and the plane of the first moving member 52 also decreases. That is, the connecting component 53 rotates relative to the first moving member 52 and the door 4.

[0138] According to some embodiments of this application, specifically, such as Figure 25 and Figure 28 As shown, the connecting assembly 53 includes a first mating shaft 531, a second mating shaft 532, and a connector 533. The connector 533 is connected to the first mating shaft 531 and the second mating shaft 532 respectively, so as to connect the first moving member 52 connected to the first mating shaft 531 to the switch door 4 connected to the second mating shaft 532, so as to ensure that the movement of the first moving member 52 can drive the switch door 4 to move.

[0139] The first moving member 52 is provided with a first groove 521 for accommodating the first mating shaft 531. The first groove 521 mates with the first mating shaft 531, realizing the connection between the first mating shaft 531 and the first groove 521. Since the force exerted by the first moving member 52 on the first mating shaft 531 is a vertical force, the opening of the first groove 521 faces the rear side. During the vertical movement of the first moving member 52, the first mating shaft 531 will not disengage from the first groove 521, and the first mating shaft 531 can rotate within the first groove 521 and move vertically under the drive of the first moving member 52.

[0140] During the vertical movement of the first mating shaft 531 driven by the first moving member 52, the connecting assembly 53 as a whole also moves vertically, and the second mating shaft 532 also moves vertically at the same time. The switch door 4 is provided with a second groove 42 to accommodate the second mating shaft 532. The second mating shaft 532 applies an external force to the switch door 4 through the groove wall of the second groove 42, driving the switch door 4 to move vertically. Since the opening of the second groove 42 faces forward, the force applied by the second mating shaft 532 to the switch door 4 can always act on the groove wall of the second groove 42. The second mating shaft 532 will not disengage from the second groove 42, and the second mating shaft 532 can rotate within the second groove 42.

[0141] When the switch door 4 moves away from or towards the first moving member 52 under the guidance of the guide groove 17, since the switch door 4 and the first moving member 52 are always parallel during the movement, the angle between the connector 533 and the switch door 4 increases during the movement of the switch door 4 away from the first moving member 52. The second mating shaft 532, which is fixedly connected to the connector 533, rotates relative to the second groove 42. The angle between the plane where the connector 533 and the first moving member 52 are located also increases. The first mating shaft 531, which is fixedly connected to the connector 533, rotates relative to the first groove 521.

[0142] As the door 4 moves toward the first moving member 52, the angle between the connecting member 533 and the door 4 decreases, the second mating shaft 532, which is fixedly connected to the connecting member 533, rotates relative to the second groove 42, the angle between the connecting assembly 53 and the plane where the first moving member 52 is located also decreases, and the first mating shaft 531, which is fixedly connected to the connecting member 533, rotates relative to the first groove 521.

[0143] like Figure 25 and Figure 28 As shown, furthermore, to prevent the first mating shaft 531 from disengaging from the first groove 521 and the second mating shaft 532 from disengaging from the second groove 42, the air conditioner 100 also includes an anti-detachment member 6. The anti-detachment member 6 engages with the first mating shaft 531 and the second mating shaft 532 respectively to prevent the first mating shaft 531 and the second mating shaft 532 from falling off. Specifically, the first mating shaft 531 is disposed between the first groove 521 and the anti-detachment member 6, that is, the anti-detachment member 6 can close the opening of the first groove 521, further ensuring that the first mating shaft 531 will not disengage from the opening of the first groove 521. The second mating shaft 532 is disposed between the second groove 42 and the anti-detachment member 6, that is, the anti-detachment member 6 can close the opening of the second groove 42, further ensuring that the second mating shaft 532 will not disengage from the opening of the second groove 42.

[0144] Reference Figure 2 , Figure 5 , Figure 8 , Figure 11 , Figure 14 and Figure 18 The front surface of the housing 1 is also provided with second air outlets 14 on both the left and right sides. Thus, the air conditioner 100 can also deliver air to the left and right through the second air outlets 14. The housing 1 also defines multiple branching air ducts 9. At least a portion of the air delivery impeller 102 is connected to the second air outlet 14 through the branching air ducts 9. Therefore, this portion of the air delivery impeller 102 can selectively deliver air to the first air outlet 2 or to the second air outlet 14. By selecting the air outlet for this portion of the air delivery impeller 102, multiple different air delivery modes can be formed, further enriching the air delivery modes of the air conditioner 100 and better enhancing its air delivery function.

[0145] Furthermore, since the movable panel 11 covers part of the first air outlet 2 in the first state, the air supply impeller 102 corresponding to the closed first air outlet 2 may cause air volume loss because it cannot supply air to the outside. When the movable panel 11 closes the first air outlet 2, the second air outlet 14 sends this part of the airflow to the outside environment, which can avoid air volume loss and ensure the air supply volume of the air conditioner 100.

[0146] like Figure 5 , Figure 8 , Figure 11 , Figure 14 and Figure 18As shown, the diversion duct 9 is equipped with a switching valve 7 to control the corresponding air supply impeller 102 to switch air supply towards the first air outlet 2 or the second air outlet 14. Specifically, the diversion duct 9 has an opening in its wall, which is connected to the first air outlet 2. When the opening is open, the airflow in the diversion duct 9 will flow through the opening to the first air outlet 2. At this time, the switching valve 7 can close the second air outlet 14 in the diversion duct 9 while guiding the airflow to the opening. The switching valve 7 can also close the opening. At this time, the airflow will flow along the diversion duct 9 to the second air outlet 14 and be blown out through the second air outlet 14.

[0147] According to some embodiments of this application, the air supply impeller 102 with the diversion air duct 9 is the middle air supply impeller 101, and the plurality of air supply impellers 102 also include a top air supply impeller 1021 and a bottom air supply impeller 102.

[0148] Specifically, refer to Figure 5 The first air outlet 2 includes an upper air outlet 21, a lower air outlet 22, and a middle air outlet 23. A top air supply impeller 1021 corresponds to the upper air outlet 21 and supplies air to it. A bottom air supply impeller 102 corresponds to the lower air outlet 22 and supplies air to it. A middle air supply impeller 101 corresponds to both the middle air outlet 23 and the second air outlet 14. Air can be selectively supplied to either the middle air outlet 23 or the second air outlet 14 via a switching valve 7. When the middle air supply impeller 101 supplies air to the second air outlet 14, the airflow passes through a diversion duct 9. When the middle air supply impeller 101 supplies air to the middle air outlet 23, the airflow passes through the diversion duct 9 and is guided by the switching valve 7 to the opening, where it is then blown out of the middle air outlet 23.

[0149] Furthermore, the housing 1 is provided with a first air duct 3, which includes an upper air duct 31 and a lower air duct 32. The air outlet sides of the top air supply impeller 1021 and the bottom air supply impeller 102 are both connected to the first air outlet 2 through the first air duct 3. The first air outlet 2 includes an upper air outlet 21 and a lower air outlet 22. The top air supply impeller 1021 is connected to the upper air outlet 21 through the upper air duct 31, and the bottom air supply impeller 102 is connected to the lower air outlet 22 through the lower air duct 32.

[0150] Furthermore, the front side of the housing 1 is provided with a recessed groove 16, which extends upward to the upper air duct 31 and downward to the lower air duct 32. The channel walls of the two branch air ducts 9 on the front side define the groove wall of the groove 16. The space inside the housing 1 located in front of the branch air ducts 9, that is, the space defined by the groove 16, is a connecting channel. When the front end of the connecting channel is closed, the connecting channel can be used to connect the two ends of the first air duct 3, that is, to connect the upper air duct 31 and the lower air duct 32. When the front side of the connecting channel is open, the front side of the connecting channel defines the first air outlet 2, that is, the middle air outlet 23.

[0151] The diversion duct 9 is provided with an opening that connects to the connecting channel. The opening connects to the connecting channel and can then connect to the first air outlet 2. When the opening is open, the airflow in the diversion duct 9 will flow through the opening to the first air outlet 2.

[0152] The opening is equipped with a switching valve 7 to control the intermediate air supply impeller 101 to supply air toward the first air outlet 2 or the second air outlet 14.

[0153] When the intermediate air supply impeller 101 supplies air towards the first air outlet 2, the switching valve 7 can close the second air outlet 14 in the diversion duct 9 while guiding the airflow to the opening. When the intermediate air supply impeller 101 supplies air towards the second air outlet 14, the switching valve 7 can also close the opening. At this time, the airflow will flow along the diversion duct 9 to the second air outlet 14 and be blown out through the second air outlet 14.

[0154] In some embodiments, the switching valve 7 is formed as a rotatable switching door with a vertically extending pivot axis. Thus, the drive structure of the switching valve 7 can be located above or below the pivot axis of the switching valve 7. The state of the switching valve 7 can be controlled by controlling the rotation of the pivot axis, without occupying extra space, which facilitates the arrangement of the internal structure of the air conditioner 100.

[0155] When the active panel 11 is in the first state, the active panel 11 covers the central air outlet 23 so that the connecting channel can connect the upper air duct 31 and the lower air duct 32.

[0156] When one of the upper air outlet 21 or the lower air outlet 22 is open and the other is closed, by setting a connecting channel between the upper air duct 31 and the lower air duct 32, the airflow in the first air duct 3 corresponding to the closed first air outlet 2 can be directed to the first air duct 3 corresponding to the open first air outlet 2, and then sent out of the air conditioner 100 through the open first air outlet 2, thus avoiding air volume loss.

[0157] The first air duct 3 includes an upper air duct 31 and a lower air duct 32 spaced apart vertically, with a connecting channel connecting the upper air duct 31 and the lower air duct 32. To ensure the uniformity of indoor temperature stratification under the control of the air conditioner 100 in this embodiment of the invention, in the cooling mode of the air conditioner 100, the air conditioner 100 can mainly send air out through the upper air outlet 21. At this time, the lower air outlet 22 and the middle air outlet 23 are closed by the movable panel 11. The airflow in the lower air duct 32 is guided to the connecting channel and flows to the upper air duct 31 through the connecting channel, mixing with the airflow in the upper air duct 31. The mixed airflow continues to flow along the upper air duct 31 and is blown to the outside through the upper air outlet 21. Since the upper air outlet 21 is located at the top, the air conditioner 100 can blow cold air to the upper part of the room, so that the upper air in the room can also have cold air flow, thereby improving the cooling effect of the air conditioner 100 on the room.

[0158] To ensure the uniformity of indoor temperature stratification under the control of the air conditioner 100 in this embodiment of the invention, in the heating mode of the air conditioner 100, the air conditioner 100 can mainly send air out through the lower air outlet 22. At this time, the upper air outlet 21 and the middle air outlet 23 are closed by the movable panel 11. The airflow in the upper air duct 31 is guided to the connecting channel and flows to the lower air duct 32 through the connecting channel, where it mixes with the airflow in the lower air duct 32. The mixed airflow continues to flow along the lower air duct 32 and is blown to the outside through the lower air outlet 22. Since the lower air outlet 22 is located at the bottom, the air conditioner 100 can blow warm air to the lower part of the room, so that the lower air in the room can also have warm air flow, thereby improving the heating effect of the air conditioner 100 on the room.

[0159] Reference Figure 2 , Figure 3 , Figures 10-15 The active panel 11 in the first state is used to close the first air outlet 2 defined by the connecting channel, so that the connecting channel can form a complete channel connecting the upper air outlet 21 and the lower air outlet 22.

[0160] Reference Figure 4 , Figures 16-19 When the active panel 11 in the second state moves to the front of the connecting channel, the connecting channel participates in defining the air guide space 8. At this time, the connecting channel cannot form a complete channel structure. After the airflow is guided by the air guide space 8, it passes through the air outlet area 82 and blows out to the surroundings through the guidance of the active panel 11.

[0161] like Figure 2 and Figure 3 As shown, the air duct 9 is equipped with a swivel blade assembly 911, which includes multiple rotatable swivel blades 911 arranged in the vertical direction. Each swivel blade 911 can swing up and down to adjust the airflow direction. In different airflow modes, the swivel blades 911 can swing upwards or downwards to achieve better airflow. For example, in the cooling mode of the air conditioner 100, each swivel blade 911 of the swivel blade assembly 911 can swing upwards, controlling the airflow direction of the second air outlet 14 to be upwards, thereby further improving the cooling effect of the air conditioner 100 and improving the uniformity of indoor temperature. In the heating mode of the air conditioner 100, each swivel blade 911 of the swivel blade assembly 911 can swing downwards, controlling the airflow direction of the second air outlet 14 to be downwards, thereby further improving the heating effect of the air conditioner 100 and improving the uniformity of indoor temperature. In the strong wind mode where the user needs stronger airflow, the swivel blades 911 can rotate to a horizontal parallel position to achieve a direct airflow effect.

[0162] like Figure 8 , Figure 11 , Figure 14 and Figure 18As shown, the housing 1 is also provided with a second air guide 131, which is rotatably disposed at the second air outlet 14 to change the air outlet direction of the diversion duct 9.

[0163] Reference Figures 1-5 The housing 1 has a first notch 13 extending along the height direction on both the left and right sides. The first notch 13 is connected to the second air outlet 14. When the air conditioner 100 blows air to the left and right sides, the airflow needs to pass through the first notch 13. A part of the first notch 13 forms the second air outlet 14.

[0164] The first notch 13 is provided with a rotatable second air guide 131, which is used to guide the air outlet direction of the second air outlet 14. The second air guide 131 is adapted to guide the air outlet direction of the second air outlet 14 to the left front or right front.

[0165] The second air guide 131 can also seal the first gap 13 when the air conditioner 100 is turned off or when the second air outlet 14 is not blowing air, so as to prevent dust or foreign objects in the external environment from entering the first gap 13 or the diversion air duct 9, and prevent foreign objects in the external environment from invading the interior of the air conditioner 100 and affecting the service life of the air conditioner 100. When the second air guide 131 seals the first gap 13, the appearance of the air conditioner 100 is flat and beautiful, which improves the aesthetics of the air conditioner 100 when it is not running.

[0166] Combination Figure 9 , Figure 12 , Figure 15 and Figure 19 In the embodiment shown, each first air duct 3 is provided with a first air guide 12, which can be rotated to guide the airflow to the connecting channel.

[0167] When the active panel 11 is in the first state, the first air guide 12 can rotate between the first state and the second state. In the first state, the first air guide 12 sends air outward, and in the second state, the first air guide 12 sends air toward the connecting channel.

[0168] The first air guide 12 guides the airflow in the first flow channel. In the first state, the first air guide 12 sends air outward. At this time, the state of the first air guide 12 controls the airflow direction of the corresponding first air outlet 2. In the second state, the first air guide 12 sends air towards the connecting channel. The first air guide 12 can guide the airflow in the first air duct 3 to the connecting channel. After being guided by the first air guide 12, the airflow can enter the connecting channel more smoothly, reducing wind resistance and avoiding airflow loss.

[0169] Each first air duct 3 is provided with a first air guide 12. The first air guide 12 located at the top can be rotated to send air upwards to switch to the first state, and the first air guide 12 located at the bottom can be rotated to send air downwards to switch to the first state.

[0170] The first air duct 3 includes an upper air duct 31 and a lower air duct 32 spaced apart vertically. The first air guide 12 includes an upper air guide 121 and a lower air guide 122. The upper air guide 121 is located in the upper air duct 31, and the lower air guide 122 is located in the lower air duct 32. The airflow is guided by the upper air guide 121 when passing through the upper air duct 31, and the airflow is guided by the lower air guide 122 when passing through the lower air duct 32.

[0171] To ensure the uniformity of indoor temperature stratification under the control of the air conditioner 100 in this embodiment of the invention, in the cooling mode of the air conditioner 100, the air conditioner 100 can mainly deliver air outward through the upper air outlet 21. At this time, the lower air guide 122 switches to the second state, that is, the lower air guide 122 guides the airflow in the lower air duct 32 to the connecting channel. The upper air guide 121 switches to the first state, that is, the upper air guide 121 rotates to deliver air upward.

[0172] The airflow in the lower air duct 32 is guided by the lower air guide 122 to the connecting channel, and flows to the upper air duct 31 through the connecting channel, where it mixes with the airflow in the upper air duct 31. The mixed airflow continues to flow along the upper air duct 31, and is guided by the upper air guide 121 as it passes through the upper air outlet 21, forming an upward oblique wind. As a result, the air conditioner 100 can blow the cold air to a higher position in the room. With the strong wind provided by the air supply impeller 102, the air supply distance of the upper air outlet 21 is increased, which can achieve the effect of cooling airflow close to the top, greatly improving the cooling comfort and uniformity.

[0173] In the heating mode of the air conditioner 100, the air conditioner 100 can mainly send air out through the lower air outlet 22. At this time, the upper air guide 121 switches to the second state, that is, the upper air guide 121 guides the airflow in the upper air duct 31 to the connecting channel. The lower air guide 122 switches to the first state, that is, the lower air guide 122 rotates to send air downwards.

[0174] The airflow in the upper air duct 31 is guided by the upper air guide 121 to the connecting channel, and flows to the lower air duct 32 through the connecting channel, where it mixes with the airflow in the lower air duct 32. The mixed airflow continues to flow along the lower air duct 32, and is guided by the lower air guide 122 as it passes through the lower air outlet 22, forming a downward-sloping airflow. As a result, the air conditioner 100 can blow hot air to a lower part of the room. Due to the strong airflow provided by the air supply impeller 102, the air supply distance of the lower air outlet 22 is increased, which can achieve the effect of heating and ground-level airflow, greatly improving the cooling comfort and uniformity.

[0175] Furthermore, in both the first and second states, the first air guide 12 extends obliquely in the vertical direction. The first air guide 12 also includes a closed state, in which the first air guide 12 can be rotated to a position extending in the vertical direction.

[0176] The first air guide 12 is formed as a plate, and its first rotation axis extends horizontally, with the direction of the first rotation axis perpendicular to the flow direction of the airflow within the first air duct 3. The angle between the first air guide 12 and the airflow direction in the first state is smaller than the angle between the first air guide 12 and the airflow direction in the second state.

[0177] According to some embodiments of this application, the top and bottom of the connecting channel are provided with breathable shielding members, the shielding members including perforated grilles, and the upper and lower openings of the connecting channel can be provided with perforated grilles to shield the connecting channel, prevent dust and foreign objects in the external environment from entering the connecting channel and causing blockage, and also ensure the aesthetics of the air conditioner 100.

[0178] like Figure 8 , Figure 11 , Figure 14 and Figure 18 As shown, the extension direction of the air outlet of the diversion duct 9 is at an angle to the front and rear direction, so that the air outlet of the diversion duct 9 can blow air to the left front or right front.

[0179] like Figure 9 , Figure 12 , Figure 15 and Figure 19 As shown, multiple air supply impellers 102 are coaxially arranged and share a common motor drive. In this way, multiple air supply impellers 102 can be driven simultaneously by one motor, which simplifies the structure of the air conditioner 100, reduces production costs, and ensures that the rotational speed of each air supply impeller 102 is the same and the air volume at the outlet of each air supply impeller 102 is uniform, thereby improving the comfort of the air supply effect of the air conditioner 100.

[0180] In other embodiments, the multiple air supply impellers 102 can be driven by multiple motors. For example, a motor can be set above the multiple air supply impellers 102 to drive one or more upper air supply impellers 102, and a motor can be set below the multiple air supply impellers 102 to drive one or more lower air supply impellers 102. By controlling the speed of multiple motors according to different needs, different air outlet effects can be achieved to meet different user needs.

[0181] According to some embodiments of this application, each air supply impeller 102 is a centrifugal impeller. Multiple centrifugal impellers can supply air outwards separately. The combined action of each centrifugal impeller can provide a larger air volume and air pressure to the outside world, supplying air to a greater distance in the radial direction. Multiple centrifugal impellers are arranged sequentially in the height direction, that is, in the axial direction of the centrifugal impellers, so that airflow can be formed at all points in the axial direction, realizing long-distance air supply in the axial direction.

[0182] In some embodiments, the central air supply impeller 102 can also be a cross-flow impeller, with a centrifugal impeller on each of its upper and lower sides. The centrifugal impeller and the cross-flow impeller can respectively supply air outward. Under the combined action of the centrifugal impeller and the cross-flow impeller, the air conditioner 100 can combine the advantages of both, using the centrifugal impeller to provide greater air volume and air pressure to the outside, supplying air to a greater distance radially, and utilizing the low power and low noise characteristics of the cross-flow impeller to reduce the noise and energy consumption of the air conditioner 100 and reduce the complexity of the air conditioner 100 structure.

[0183] Reference Figure 21 The air supply impeller 102 is a dual-inlet centrifugal impeller. The air inlets of the centrifugal impeller are set vertically upward and downward, that is, the centrifugal impeller is axially inlet from both sides. The airflow can be fully heat-exchanged in the process of flowing to the centrifugal impeller, resulting in better cooling or heating effect.

[0184] Alternatively, the centrifugal impeller can be a single-inlet centrifugal impeller. Specifically, the uppermost centrifugal impeller is a single-inlet centrifugal impeller, with the air intake located above the air supply impeller 102 and vertically upward, while the lowermost centrifugal impeller is a single-inlet centrifugal impeller, with the air intake located below the air supply impeller 102 and vertically downward.

[0185] A specific embodiment of the air conditioner 100 is described below with reference to the accompanying drawings.

[0186] like Figures 1-28 As shown, the air conditioner 100 includes: a housing 1, four air supply impellers 102, a movable panel 11, and a door 4.

[0187] The four air supply impellers 102 are coaxially arranged and share a common motor-driven centrifugal impeller to provide greater air volume and air pressure to the outside. The centrifugal impeller at the top is the top air supply impeller 1021, the centrifugal impeller at the bottom is the bottom air supply impeller 102, and the two centrifugal impellers in the middle are the middle air supply impellers 102.

[0188] The front side of the housing 1 is provided with a first air outlet 2 arranged sequentially along the height direction. The first air outlet 2 includes an upper air outlet 21, a lower air outlet 22, and a middle air outlet 23. A second air outlet 14 is also provided on both sides of the middle air outlet 23. The housing 1 also defines a first air duct 3 and a diversion air duct 9. The first air duct 3 includes an upper air duct 31 and a lower air duct 32. The top air supply impeller 1021 supplies air to the upper air outlet 21 through the upper air duct 31, the bottom air supply impeller 102 supplies air to the lower air outlet 22 through the lower air duct 32, and the middle air supply impeller 102 supplies air to the second air outlet 14 through the diversion air duct 9.

[0189] The first air guide 12 includes an upper air guide 121 and a lower air guide 122. The upper air guide 121 is located in the upper air duct 31, and the lower air guide 122 is located in the lower air duct 32. The airflow is guided by the upper air guide 121 when passing through the upper air duct 31, and the airflow is guided by the lower air guide 122 when passing through the lower air duct 32.

[0190] The front side of the housing 1 has a recessed groove 16, which extends upward to the upper air duct 31 and downward to the lower air duct 32. The channel walls of the two branch air ducts 9 on the front side define the groove wall of the groove 16. The space inside the housing 1 located in front of the branch air ducts 9, that is, the space defined by the groove 16, is a connecting channel. When the front end of the connecting channel is closed, the connecting channel can be used to connect the two ends of the first air duct 3, that is, to connect the upper air duct 31 and the lower air duct 32. When the front side of the connecting channel is open, the front side of the connecting channel defines the first air outlet 2, that is, the middle air outlet 23.

[0191] An opening is provided on the wall of the diversion duct 9, which is connected to the central air outlet 23. A switching valve 7 is provided on the opening to control the central air supply impeller 101 to supply air towards the first air outlet 2 or the second air outlet 14. When the central air supply impeller 101 supplies air towards the first air outlet 2, the switching valve 7 can close the second air outlet 14 in the diversion duct 9 while guiding the airflow to the opening. When the central air supply impeller 101 supplies air towards the second air outlet 14, the switching valve 7 can also close the opening. At this time, the airflow will flow along the diversion duct 9 to the second air outlet 14 and be blown out through the second air outlet 14.

[0192] The diversion duct 9 is equipped with a sway vane assembly 911, which includes multiple rotatable sway vanes 911 arranged in the height direction. Each sway vane 911 can swing up and down to adjust the air outlet direction. In different air outlet modes, the sway vanes 911 can be selected to swing upward or downward to achieve better air outlet effect. The housing 1 is also equipped with a second air guide 131, which is rotatably disposed at the second air outlet 14 to change the air outlet direction of the diversion duct 9.

[0193] The movable panel 11 is connected to the housing 1 via the connecting rod 1122 assembly 112 so that it can swing relative to the housing 1. By swinging the movable panel 11, the movable panel 11 can swing to a first position, a second position, and a third position between the second and third positions. In the first and second positions, the movable panel 11 is in the first state, and in the third position, the movable panel 11 is in the second state.

[0194] When the movable panel 11 is in the first state, it covers the middle air outlet 23, allowing the connecting channel to connect the upper air duct 31 and the lower air duct 32. When the movable panel 11 is moved to the first position in the first state, it covers the front of the lower air outlet 22 and the middle air outlet 23, closing them. When the movable panel 11 is moved to the second position in the first state, it covers the front of the upper air outlet 21 and the middle air outlet 23, closing them.

[0195] When the air conditioner 100 is turned off, the door 4 closes the upper air outlet 21. Together with the movable panel 11, the door 4 closes all the first air outlets 2 when the air conditioner 100 is turned off, ensuring the aesthetic appearance of the air conditioner 100 when it is turned off and preventing foreign objects from the outside environment from entering the air conditioner 100, thus ensuring the service life of the air conditioner 100.

[0196] The air conditioner 100, when turned on, includes at least three modes, including:

[0197] like Figure 2 , Figures 10-12 In the first mode shown, when the air conditioner 100 is in the first mode, the movable panel 11 is in the first position, covering the front of the lower air outlet 22 and the middle air outlet 23, thus closing the lower air outlet 22 and the middle air outlet 23. The movable panel 11 covering the middle air outlet 23 allows the connecting channel to connect the upper air duct 31 and the lower air duct 32. The upper air guide plate of the air conditioner 100 rotates to send air upwards to switch to the first state, and the lower air guide plate of the air conditioner 100 rotates to send air towards the connecting channel to switch to the second state. The second air guide 131 rotates to the position of opening the first notch 13 to switch to the open state. Each blade 911 of the sway blade 911 assembly 91 can swing upwards to control the air outlet 14 to send air upwards. The opening and closing door 4 opens the upper air outlet 21, and the middle air supply impeller 101 sends air towards the second air outlet 14. The switching valve 7 closes the opening, and the airflow flows along the diversion duct 9 to the second air outlet 14 and is blown out through the second air outlet 14.

[0198] The first mode is usually activated when the air conditioner 100 is cooling. In the cooling mode of the air conditioner 100, the air conditioner 100 mainly sends air out through the upper air outlet 21 and the second air outlet 14. At this time, the airflow in the lower air duct 32 driven by the bottom air supply impeller 102 is guided by the lower air guide 122 to the connecting channel, and flows to the upper air duct 31 through the connecting channel, where it mixes with the airflow in the upper air duct 31. The mixed airflow continues to flow along the upper air duct 31. During the process of passing through the upper air duct 31, it is guided by the upper air guide 121 and blown to the outside through the upper air outlet 21, forming an upward oblique wind. As a result, the air conditioner 100 can blow the cold air to a higher place in the room. Since the centrifugal impeller can provide stronger wind force, it increases the air delivery distance of the upper air outlet 21, which can achieve the effect of cooling airflow close to the top, greatly improving the cooling comfort and uniformity.

[0199] like Figure 3 , Figures 13-15 In the second mode shown, when the air conditioner 100 is in the second mode, the movable panel 11 is in the second position, covering the front of the upper air outlet 21 and the middle air outlet 23, thus closing the upper air outlet 21 and the middle air outlet 23. The movable panel 11 covering the middle air outlet 23 allows the connecting channel to connect the upper air duct 31 and the lower air duct 32. The lower air guide plate of the air conditioner 100 rotates to downward airflow to switch to the first state, and the upper air guide plate of the air conditioner 100 rotates to airflow towards the connecting channel to switch to the second state. The second air guide 131 rotates to the position of opening the first notch 13 to switch to the open state. Each blade 911 of the sway blade 911 assembly 91 can swing downward to control the airflow direction of the second air outlet 14 to downward. The opening and closing door 4 opens the upper air outlet 21, and the middle air supply impeller 101 supplies air towards the second air outlet 14. The switching valve 7 closes the opening, and the airflow flows along the diversion duct 9 to the second air outlet 14 and is blown out through the second air outlet 14.

[0200] The second mode is usually activated when the air conditioner 100 is in heating mode. In the heating mode of the air conditioner 100, the air conditioner 100 mainly sends air out through the lower air outlet 22 and the second air outlet 14. At this time, the airflow in the upper air duct 31 driven by the top air supply impeller 1021 is guided by the upper air guide 121 to the connecting channel, and flows to the lower air duct 32 through the connecting channel, mixing with the airflow in the lower air duct 32. The mixed airflow continues to flow along the lower air duct 32. During the process of passing through the lower air duct 32, it is guided by the lower air guide 122 and blown to the outside through the lower air outlet 22, forming a downward oblique wind. Thus, the air conditioner 100 can blow hot air to a lower part of the room. Since the centrifugal impeller can provide stronger wind force, the air delivery distance of the lower air outlet 22 is increased, which can achieve the effect of heating and ground-level air delivery, greatly improving the heating comfort and uniformity.

[0201] like Figure 4, Figures 16-19 In the third mode shown, when the air conditioner 100 is in the third mode, the movable panel 11 is located on the front side of the housing 1 and spaced apart from the housing 1. The movable panel 11 and the housing 1 define an air guide space 8. The air guide space 8 has an air outlet area 82, which surrounds the movable panel 11. At least part of the first air outlet 2 sends air into the air guide space 8. The upper air guide plate of the air conditioner 100 rotates to send air into the air guide space 8 at an angle downward to switch to the fourth state. The lower air guide plate of the air conditioner 100 rotates to send air into the air guide space 8 at an angle upward to switch to the fourth state. The second air guide member 131 rotates to the position of closing the first notch 13 to switch to the closed state. The switch door 4 opens the upper air outlet 21. The middle air supply impeller 101 sends air towards the middle air outlet 23. The switching valve 7 opens its opening and guides the airflow to the opening. The airflow flows along the diversion air duct 9 to the opening and is then blown out through the middle air outlet 23.

[0202] The third mode is usually activated when the air conditioner 100 needs to provide airflow throughout the room. In the air conditioner 100's airflow mode, the air conditioner 100 gathers all the airflow through the air guide space 8 and then sends the airflow to all directions through the air outlet area 82. As a result, the air conditioner 100 can blow the air to all parts of the room and generate strong airflow in all directions.

[0203] When the air conditioner is off (100%), such as Figure 1 , Figures 6-9 As shown, the upper air guide plate of the air conditioner 100 rotates to be parallel to the vertical direction to switch to the third state, the lower air guide plate of the air conditioner 100 rotates to be parallel to the vertical direction to switch to the third state, the second air guide 131 rotates to the position of closing the first notch 13 to switch to the closed state, the switch door 4 moves to the position of closing the upper air outlet 21, the switching valve 7 closes the opening, and the movable panel 11 swings to the first position.
