Description

Technical Field

[0001] This invention relates to the field of household appliances, and in particular to an air conditioner. Background Technology

[0002] Traditional floor-standing air conditioners typically use a single cross-flow fan or a single centrifugal fan to drive airflow, with only one air outlet. The airflow direction is changed by the oscillation of the blades, resulting in a single air outlet pattern. Furthermore, cross-flow fans have relatively small air volume and air pressure, which cannot provide sufficient air volume and cannot achieve long-distance radial air delivery. Centrifugal fans, on the other hand, have a relatively fixed structure, making it difficult to achieve long-distance axial air delivery, and the resulting airflow is not uniform. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide an air conditioner that can provide greater air volume and air pressure to the outside, offers more diverse air outlet patterns, results in a more uniform indoor temperature distribution, and improves the user experience.

[0006] According to the embodiments of this application, the air conditioner, on the one hand, by setting multiple centrifugal impellers arranged sequentially in the height direction, can use multiple centrifugal impellers to send air outwards separately.

The multiple centrifugal impellers arranged sequentially in the height direction realize long-distance air delivery of the air conditioner in the impeller axis. On the other hand, by setting a first air outlet and a second air outlet in the height direction, and setting a first centrifugal impeller that can directly send air to the first air outlet and a second centrifugal impeller that can directly send air to the second air outlet, the airflow velocity at the air outlet is faster and the wind force is stronger.

[0078] Traditional floor-standing air conditioners typically use a single cross-flow fan or a single centrifugal fan to drive airflow, with only one air outlet. The airflow direction is changed by the oscillation of the blades, resulting in a single air outlet pattern. Furthermore, cross-flow fans have relatively small air volume and air pressure, which cannot provide sufficient air volume and cannot achieve long-distance radial air delivery. Centrifugal fans, on the other hand, have a relatively fixed structure, making it difficult to achieve long-distance axial air delivery, and the resulting airflow is not uniform.

[0079] To address this, this invention provides an air conditioner 100 comprising multiple centrifugal impellers 2 arranged sequentially in the vertical direction. Each centrifugal impeller 2 can individually deliver air outwards. The combined action of these impellers provides greater airflow and pressure, delivering air over greater radial distances. The sequential arrangement of the centrifugal impellers 2 in the vertical direction, i.e., in the axial direction, ensures airflow at all points along the axial direction, achieving long-distance axial air delivery. The air conditioner 100 also includes a first air outlet 11 and a second air outlet 12 arranged in the vertical direction. The centrifugal impellers 2 include a first centrifugal impeller 21 capable of directly delivering air to the first air outlet 11 and a second centrifugal impeller 22 capable of directly delivering air to the second air outlet 12. Therefore, the airflow from each outlet is sufficiently strong. By controlling whether and where each outlet delivers air, various different airflow patterns can be created, enriching the airflow patterns of the air conditioner 100, better realizing its various functions, and providing a better user experience.

[0080] The following is for reference. Figures 1-34 An air conditioner 100 according to an embodiment of the present invention is described.

[0081] like Figures 1-21 As shown, this application embodiment provides an air conditioner 100, which includes: a casing and a plurality of centrifugal impellers 2.

[0082] The casing is provided with an air inlet 13. Air enters the cavity defined by the casing from the air inlet 13. The air is driven by the centrifugal fan 2 located in the cavity defined by the casing to form an airflow. The airflow is blown out through the air outlet located on the front side of the casing.

[0083] The air conditioner 100 includes multiple centrifugal impellers 2 arranged sequentially in the height direction and disposed in the casing. The multiple centrifugal impellers 2 can each send air outward. The multiple centrifugal impellers 2 work together to provide greater air volume and air pressure to the outside, and send air to a greater distance in the radial direction. The multiple centrifugal impellers 2 are arranged sequentially in the height direction, that is, in the axial direction of the centrifugal impellers 2. Airflow can be formed at all points in the axial direction, realizing long-distance air delivery in the axial direction.

[0084] The front side of the casing has a first air outlet 11 and a second air outlet 12 arranged in the height direction, wherein the first air outlet 11 is located above the second air outlet 12. The first air outlet 11 and the second air outlet 12 can send air out separately or simultaneously. In the cooling mode of the air conditioner, cold air has the characteristic of flowing downward in the room. In order to ensure the uniformity of indoor temperature stratification, the air conditioner 100 can mainly send air out through the first air outlet 11 so that the upper air in the room can also have cold air flow, thereby improving the cooling effect of the air conditioner 100. In the heating mode of the air conditioner, hot air has the characteristic of flowing upward in the room. In order to ensure the uniformity of indoor temperature stratification, the air conditioner 100 can mainly send air out through the second air outlet 12 so that the lower temperature in the room can also be raised, thereby improving the heating effect of the air conditioner 100.

[0085] The first air outlet 11 and the second air outlet 12 can also simultaneously send air outwards to meet the user's needs for airflow from all directions.

[0086] Therefore, by controlling whether air is emitted from each air outlet and the direction of air emission, a variety of different air emission modes can be formed, enriching the air emission forms of the air conditioner 100, better realizing the various functions of the air conditioner 100, and giving users a better experience.

[0087] Among the multiple centrifugal impellers 2, the top first centrifugal impeller 21 is correspondingly arranged with the first air outlet 11 to deliver air towards the first air outlet 11. Thus, the airflow generated from the outlet of the first centrifugal impeller 21 can be directly blown out through the first air outlet 11, reducing wind resistance and ensuring the wind speed and volume of the airflow from the first air outlet 11, thereby ensuring the air outlet distance of the air conditioner 100. The bottom second centrifugal impeller 22 is correspondingly arranged with the second air outlet 12 to deliver air towards the second air outlet 12. Thus, the airflow generated from the outlet of the second centrifugal impeller 22 can be directly blown out through the second air outlet 12, reducing wind resistance and ensuring the wind speed and volume of the airflow from the second air outlet 12, thereby ensuring the air outlet distance of the air conditioner 100.

[0088] According to the embodiments of this application, the air conditioner 100, on the one hand, by setting multiple centrifugal impellers 2 arranged sequentially in the height direction, can use multiple centrifugal impellers 2 to send air outwards respectively. Under the joint action of each centrifugal impeller 2, it can provide a larger air volume and air pressure to the outside, and send air to a farther distance in the radial direction. The multiple centrifugal impellers 2 are arranged sequentially in the height direction, realizing long-distance air delivery of the air conditioner 100 in the impeller axis. On the other hand, by setting a first air outlet 11 and a second air outlet 12 in the height direction, and setting a first centrifugal impeller 21 that can directly send air to the first air outlet 11 and a second centrifugal impeller 22 that can directly send air to the second air outlet 12 respectively, the airflow velocity at the air outlet is faster and the wind force is stronger. By controlling whether each air outlet sends air and the direction of air outlet, a variety of different air outlet modes can be formed, enriching the air outlet form of the air conditioner 100, better realizing the various functions of the air conditioner 100, and giving users a better experience.

[0089] Combination Figures 4-21 In the embodiment shown, the housing is provided with a first air duct 31 that connects the first air outlet 11 and the first centrifugal impeller 21, and a second air duct 32 that connects the second air outlet 12 and the second centrifugal impeller 22. The housing is also provided with a connecting channel 33 that connects the first air duct 31 and the second air duct 32.

[0090] In different modes of the air conditioner 100, the airflow inside the air conditioner 100 has different flow directions to achieve different air output effects, and the air conditioner 100 can achieve better indoor temperature regulation.

[0091] Specifically, the first air outlet 11 is located above the second air outlet 12. Cold air tends to flow downwards in the room, resulting in lower temperatures at the bottom and higher temperatures at the top. Conversely, warm air tends to flow upwards in the room, resulting in lower temperatures at the bottom and higher temperatures at the top.

[0092] 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, such as Figure 5 As shown, the air conditioner 100 can mainly send air out through the first air outlet 11. At this time, the second air outlet 12 is closed, and the airflow in the second air duct 32 is guided by the structure of the second air outlet 12 to the connecting channel 33. The airflow flows to the first air duct 31 through the connecting channel 33 and mixes with the airflow in the first air duct 31. The mixed airflow continues to flow along the first air duct 31 and is blown to the outside through the first air outlet 11. Since the first air outlet 11 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.

[0093] 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, such as Figure 6 As shown, the air conditioner 100 can mainly send air out through the second air outlet 12. At this time, the first air outlet 11 is closed, and the airflow in the first air duct 31 is blocked by the first air outlet 11. The structure of the first air outlet 11 guides the airflow to the connecting channel 33, and flows to the second air duct 32 through the connecting channel 33. It mixes with the airflow in the second air duct 32. The mixed airflow continues to flow along the second air duct 32 and is blown to the outside through the second air outlet 12. Since the second air outlet 12 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.

[0094] The air conditioner 100 may also include a full-area air outlet mode. When the user needs air to be ventilated in multiple directions, the air conditioner 100 can control the first air outlet 11 and the second air outlet 12 on the casing to vent air outward simultaneously. At this time, the first centrifugal impeller 21 vents air to the first air outlet 11 through the first air duct 31 to meet the user's need for air from above, and the second centrifugal impeller 22 vents air to the second air outlet 12 through the second air duct 32 to meet the user's need for air from below.

[0095] Due to the connection channel 33, when one of the first air outlet 11 and the second air outlet 12 is closed, the airflow from the centrifugal impeller 2 corresponding to the closed air outlet can be guided to the other open air outlet. When the air outlet direction of the air conditioner 100 is controlled by opening and closing the first air outlet 11 or the second air outlet 12, the air volume generated by the corresponding centrifugal impeller 2 will not be lost, thus ensuring the air volume of the air conditioner 100.

[0096] According to some embodiments of this application, the upper and lower openings of the connecting channel 33 may be provided with perforated grilles to prevent foreign objects from entering the connecting channel 33 and to make the air conditioner 100 more aesthetically pleasing during use.

[0097] Reference Figures 1-6 The housing includes a housing 1 and a movable panel 15. A first air outlet 11 and a second air outlet 12 are located on the front side wall 101 of the housing 1. The movable panel 15 is movable relative to the housing 1 to open or close at least one of the first air outlet 11 and the second air outlet 12. In other words, the movable panel 15 is mainly used to control the opening or closing of the first air outlet 11 and / or the second air outlet 12.

[0098] In some embodiments, the air conditioner 100 includes at least two movable panels 15. One of the two movable panels 15 is used to control the opening and closing of the first air outlet 11, and the other movable panel 15 is used to control the opening and closing of the second air outlet 12. By controlling the position of the multiple movable panels 15, the air outlet mode of the air conditioner 100 can be controlled.

[0099] In some other embodiments, the movable panel 15 includes at least two, one of which is used to control the opening and closing of the first air outlet 11, and the other of which is used to simultaneously control the opening and closing of the first air outlet 11 and the second air outlet 12. By controlling the position of the multiple movable panels 15, the air outlet mode of the air conditioner 100 can be controlled.

[0100] In some other embodiments, such as Figures 1-6 As shown, the active panel 15 includes one, which simultaneously controls the opening and closing of the first air outlet 11 and the second air outlet 12.

[0101] In some embodiments, the housing 1 defines a communication channel 33 that extends vertically through a portion of the housing 1 located between the first air duct 31 and the second air duct 32, with its top opening communicating with the first air duct 31 and its bottom opening communicating with the second air duct 32.

[0102] In other embodiments, combined with Figures 4-6 , Figure 12 , Figure 16 and Figure 20 In the embodiment shown, the connecting channel 33 can be defined by the housing 1 and the movable panel 15 to reduce the manufacturing difficulty of the air conditioner 100 and make the airflow to the connecting channel 33 smoother, reducing the wind resistance during the process of the airflow being blocked by the movable panel 15 and turning to flow to the connecting channel 33.

[0103] Specifically, the front side of the housing 1 is provided with a recessed groove 16, which extends upward to the first air duct 31 and downward to the second air duct 32. The movable panel 15 covers the groove 16, and the movable panel 15 and the groove 16 cooperate to define the communication channel 33. During the movement of the movable panel 15 between the first position and the second position, it always covers the outside of the groove 16, and together with the groove 16, defines the communication channel 33.

[0104] Reference Figures 1-21 The active panel 15 is configured such that when one of the first air outlet 11 and the second air outlet 12 is closed, the other is in the open state.

[0105] Specifically, the movable panel 15 can move between a first position where the second air outlet 12 is closed and the first air outlet 11 is opened, and a second position where the first air outlet 11 is closed and the second air outlet 12 is opened. In some embodiments, the movable panel 15 can move horizontally in a vertical manner, and in other embodiments, the movable panel 15 can swing around a set of rotation centers.

[0106] By controlling the position of the active panel 15, the air outlet status of the first air outlet 11 and the second air outlet 12 of the air conditioner 100 can be controlled. When the movable panel 15 controls the second air outlet 12 to be fully open and the first air outlet 11 to be fully closed, the air conditioner 100 is in a state where the second air outlet 12 located below the air conditioner 100 is used as the main air outlet. In the heating mode of the air conditioner 100, the air conditioner 100 can mainly send air out through the second air outlet 12. This can be achieved by controlling the movable panel 15 to move to the first position, at which time the first air outlet 11 is closed. The airflow in the first air duct 31 is guided by the movable panel 15, which closes the first air outlet 11, to the connecting channel 33. The airflow flows through the connecting channel 33 to the second air duct 32 and mixes with the airflow in the second air duct 32. The mixed airflow continues to flow along the second air duct 32 and is blown to the outside through the second air outlet 12. Since the second air outlet 12 is located at the bottom, the air conditioner 100 can blow cold 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.

[0107] When the movable panel 15 controls the first air outlet 11 to be fully open and the second air outlet 12 to be fully closed in the second position, the air conditioner 100 is in a state where the first air outlet 11 located above the air conditioner 100 is used as the main air outlet. In the cooling mode of the air conditioner 100, the air conditioner 100 can mainly send air out through the first air outlet 11. This means that the movable panel 15 can be controlled to move to the second position. At this time, the second air outlet 12 is closed, and the airflow in the second air duct 32 is guided by the movable panel 15 that closes the second air outlet 12 to the connecting channel 33. The airflow flows to the first air duct 31 through the connecting channel 33 and mixes with the airflow in the first air duct 31. The mixed airflow continues to flow along the first air duct 31 and is blown to the outside through the first air outlet 11. Since the first air outlet 11 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.

[0108] like Figures 1-21As shown, the movable panel 15 can slide up and down relative to the housing 1. When the movable panel 15 slides down to its lowest limit position, it is in the first position, which is the position where the second air outlet 12 is closed and the first air outlet 11 is open. When the movable panel 15 slides up to its highest limit position, it is in the second position, which is the position where the second air outlet 12 is open and the first air outlet 11 is closed. In some embodiments, the movable panel 15 can also slide to an intermediate position between the first and second positions, which is the position where the first air outlet 11 and the second air outlet 12 are opened or partially opened simultaneously. In this case, the air conditioner 100 vents air from both the top and bottom simultaneously, which can meet the needs of the air conditioner 100's all-area air outlet mode.

[0109] By simply sliding the active panel 15 up and down, the opening and closing of the first air outlet 11 and the second air outlet 12 can be controlled simultaneously. The control method is simple, which simplifies the structure of the air conditioner 100 and reduces production costs.

[0110] Reference Figure 1 , Figures 4-8 , Figure 9 and Figure 10 The housing also includes a switch panel 4, which is used to open or close one of the first air outlet 11 and the second air outlet 12. The switch panel 4 and the movable panel 15 cooperate to simultaneously close the first air outlet 11 and the second air outlet 12.

[0111] When the air conditioner 100 is turned off, the switch panel 4 closes one of the first air outlet 11 and the second air outlet 12. When the switch panel 4 closes one of the first air outlet 11 and the second air outlet 12, the movable panel 15 is positioned such that one of the first air outlet 11 and the second air outlet 12 is open and the other is closed. At this time, the switch panel 4 and the movable panel 15 can jointly close the air outlet area on the front side of the housing 1. When the air conditioner 100 is turned off, the surface of the air conditioner 100 is flat, ensuring the aesthetics of the air conditioner 100 and preventing external dust from entering.

[0112] When the air conditioner 100 is turned on, the switch panel 4 opens the air outlet that was closed to avoid affecting the movement path of the movable panel 15. At this time, one of the first air outlet 11 and the second air outlet 12 opens as the switch panel 4 moves. Then, the air outlet mode of the air conditioner 100 can be controlled by controlling the movable panel 15.

[0113] In other words, the movable panel 15 can only move freely between the first position and the second position when the switch panel 4 is moved to the position where the corresponding air outlet is open.

[0114] like Figure 7 and Figure 8As shown, the switch panel 4 is movably located inside the front sidewall 101 of the housing 1 to avoid the movement path of the movable panel 15.

[0115] When the air conditioner 100 is turned off and one of the first air outlet 11 and the second air outlet 12 is closed, the switch panel 4 is flush with the front side wall 101 of the housing 1 to ensure that the front surface of the air conditioner 100 is flat and aesthetically pleasing when it is turned off, and that external dust does not easily accumulate.

[0116] After the air conditioner 100 is turned on, in order to open one of the first air outlet 11 and the second air outlet 12 while avoiding the movement path of the movable panel 15, the switch panel 4 should move to the side away from the movable panel 15 to open one of the first air outlet 11 and the second air outlet 12.

[0117] When the switch panel 4 is moved to the open position, it will overlap with the housing 1 of the air conditioner 100. The switch panel 4 moves away from the movable panel 15 while opening one of the first air outlet 11 and the second air outlet 12.

[0118] In some embodiments, the switch panel 4 moves to the outside of the housing 1 after the air conditioner 100 is turned on.

[0119] In other embodiments, reference is made to Figure 8 The switch panel 4 moves inside the housing 1 after the air conditioner 100 is turned on. The housing 1 is used to store the switch panel 4, preventing it from being damaged by external forces in the external environment.

[0120] Combination Figure 7 , Figure 8 , Figures 22-25 In the embodiment shown, one of the housing 1 and the switch panel 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. The switch panel 4 moves under the guidance of the guide groove 17 to ensure the stability of the movement of the switch panel 4.

[0121] Among them, reference Figure 7 and Figure 8 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 panel 4 closes the corresponding air outlet. The front of the air conditioner 100 is the side of the switch panel 4 away from the centrifugal fan 2, and the rear of the air conditioner 100 is the side of the switch panel 4 facing the centrifugal fan 2.

[0122] Specifically, when the corresponding air outlet is opened, the switch panel 4 first moves backward a certain distance so that the switch panel 4 and the front side wall 101 of the housing 1 change from being on the same plane to a state where the front side wall 101 of the housing 1 is in front and the switch panel 4 is behind, so that the switch panel 4 can be subsequently stored inside the housing 1, behind the front side wall 101 of the housing 1.

[0123] In some embodiments, refer to Figure 7 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 15. Therefore, while driving the switch panel 4 to move away from the movable panel 15, the switch panel 4 will also move rearward under the guidance of the guide groove 17. At the same time as driving the switch panel 4 to move closer to the movable panel 15, the switch panel 4 will also move from the rear to the front side, which is on the same plane as the front side wall 101 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.

[0124] like Figures 22-27 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 switch panel 4 through the connecting assembly 53.

[0125] 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.

[0126] 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 reciprocates vertically under the driving force of the first drive member 51 transmitted by the first gear set 54. The switch panel 4 is connected to the first moving rack through a connecting assembly 53. With the connection of the connecting assembly 53, the switch panel 4 can move in a direction away from and / or close to the first moving rack.

[0127] 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 101 of the housing 1.

[0128] 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.

[0129] 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.

[0130] like Figure 8 , Figure 26 and Figure 27 As shown, the connecting component 53 is rotatably engaged with the first moving part 52 and the switch panel 4 respectively. Since the switch panel 4 and the first moving part 52 are always parallel during the movement, the angle between the connecting component 53 and the switch panel 4 increases as the switch panel 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 panel 4.

[0131] As the switch panel 4 moves toward the first moving member 52, the angle between the connecting component 53 and the switch panel 4 decreases, and the angle between the connecting component 53 and the plane where the first moving member 52 is located also decreases. That is, the connecting component 53 rotates relative to the first moving member 52 and the switch panel 4.

[0132] According to some embodiments of this application, specifically, such as Figure 26 and Figure 27 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 panel 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 panel 4 to move.

[0133] 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.

[0134] 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 panel 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 panel 4 through the groove wall of the second groove 42, driving the switch panel 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 panel 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.

[0135] When the switch panel 4 moves away from or towards the first moving member 52 under the guidance of the guide groove 17, since the switch panel 4 and the first moving member 52 are always parallel during the movement, the angle between the connector 533 and the switch panel 4 increases during the movement of the switch panel 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.

[0136] As the switch panel 4 moves toward the first moving member 52, the angle between the connector 533 and the switch panel 4 decreases, the second mating shaft 532, which is fixedly connected to the connector 533, rotates relative to the second groove 42, the angle between the connecting component 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 connector 533, rotates relative to the first groove 521.

[0137] like Figure 23 , Figure 26 and Figure 27As 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.

[0138] Reference Figures 2-6 , Figure 12 , Figure 16 and Figure 20 The centrifugal impellers 2 also include at least one third centrifugal impeller 23 located in the middle. One or more third centrifugal impellers 23 are located between the first centrifugal impeller 21 and the second centrifugal impeller 22. The front side of the casing is provided with a central air outlet 14. In the height direction, the central air outlet 14 is located between the first air outlet 11 and the second air outlet 12, so as to correspond to the outlet of one or more third centrifugal impellers 23 located between the first centrifugal impeller 21 and the second centrifugal impeller 22. The centrifugal impellers 2 in the middle are correspondingly arranged with the central air outlet 14 to deliver air toward the central air outlet 14.

[0139] Thus, the first centrifugal impeller 21 at the top of the multiple centrifugal impellers 2 corresponds to the first air outlet 11 to send air towards the first air outlet 11, the second centrifugal impeller 22 at the bottom corresponds to the second air outlet 12 to send air towards the second air outlet 12, and one or more third centrifugal impellers 23 in the middle correspond to the middle air outlet 14 located between the first air outlet 11 and the second air outlet 12 to send air towards the middle air outlet 14.

[0140] Each air outlet has a corresponding centrifugal impeller 2 for supplying air, ensuring the air outlet speed and air volume of each outlet and improving the user experience.

[0141] like Figure 2 , Figure 3 , Figure 12 , Figure 16 and Figure 20 As shown, the air outlets 14 are provided on both the left and right sides of the casing. The air outlets 14 on the left and right sides of the casing can deliver air to the left and right sides of the air conditioner 100 respectively. Thus, the air conditioner 100 can deliver air in all directions, ensuring that the air conditioner 100 can deliver air evenly to the room.

[0142] Furthermore, in the left and right direction, the first air outlet 11 and the second air outlet 12 are located between the middle air outlet 14 on the left and right sides. That is to say, the air conditioner 100 sends air forward through the first air outlet 11 and the second air outlet 12, and sends air to the left and right sides through the middle air outlet 14. Thus, the air conditioner 100 can send air in all directions, ensuring the air supply effect of the air conditioner 100.

[0143] The middle air outlets 14 on the left and right sides are located on the left and right sides of the first air outlet 11 and the second air outlet 12. No air outlets are provided in the part between the first air outlet 11, the second air outlet 12 and the middle air outlet 14, which can avoid direct airflow and improve air comfort. In addition, the part of the structure between each air outlet can be used to arrange the movable panel 15, the first drive component 5 and other structures, making the overall structure of the air conditioner 100 more reasonable.

[0144] like Figure 12 , Figure 16 and Figure 20 As shown, the casing is provided with at least two split air ducts 34, which are used to guide the airflow generated at the outlet of the centrifugal impeller 2 to the middle air outlets 14 on the left and right sides respectively.

[0145] The central air outlet 14 is connected to the air outlet side of the third centrifugal impeller 23 via the diversion duct 34, which reduces airflow resistance and avoids airflow loss. The second drive device for driving the movable panel 15 is located in the central cavity defined between the two diversion ducts 34, which also forms a connecting channel 33. By placing the second drive device in the central cavity defined between the two diversion ducts 34, the overall structure of the air conditioner 100 is more compact, reducing the overall volume of the air conditioner 100.

[0146] Reference Figures 28-34 The air conditioner 100 also includes a second drive component 7, which includes a second drive member 71 and a second transmission assembly. The second transmission assembly includes a second moving member 72. The second drive member 71 cooperates with the second transmission assembly to drive the second moving member 72 to reciprocate. The second moving member 72 cooperates with the movable panel 15.

[0147] In some embodiments, such as Figure 29 As shown, the second driving member 71 includes two second driving motors respectively disposed on both sides of the second moving member 72. The second moving member 72 includes a second moving rack with teeth on both sides in the width direction. The second transmission assembly also includes two sets of second gears 55, which are symmetrically disposed on both sides of the second moving rack and respectively mesh with the teeth on both sides of the second moving rack.

[0148] The second gear set 55 includes a fourth gear 73, a fifth gear 74, and a sixth gear 75. The fourth gear 73 is fixedly connected to the drive shaft of the second drive motor. The fourth gear 73 meshes with the fifth gear 74. The fifth gear 74 and the sixth gear 75 are coaxially fixedly connected. The sixth gear 75 meshes with the second movable rack. Thus, the second movable rack moves vertically reciprocally under the driving force of the second drive member 71 transmitted by the second gear set 55. The movable panel 15 is fixedly connected to the second movable rack.

[0149] The second drive component 7 also includes a second mounting box 76, which is fixedly connected to the housing. In some embodiments, the second mounting box 76 is fixedly disposed in the groove 16.

[0150] The second mounting box 76 includes a second guide rail 77 extending from inside the second mounting box 76 to outside the second mounting box 76. The movable panel 15 moves under the guidance of the second guide rail 77. A second movable rack is vertically movable and guides the second guide rail 77. A second gear set 55 is rotatably disposed inside the second mounting box 76. A second drive member 71 is fixedly disposed outside the second mounting box 76, and the drive shaft of the second drive member 71 passes through the second mounting box 76 and is fixedly connected to the fourth gear 73 in the second gear set 55 disposed inside the second mounting box 76.

[0151] According to some embodiments of this application, in conjunction with Figures 1-21 In the illustrated embodiment, the casing contains a first air duct 31 connecting the first air outlet 11 and the first centrifugal impeller 21, and a second air duct 32 connecting the second air outlet 12 and the second centrifugal impeller 22. The casing also contains a connecting channel 33 connecting the first air duct 31 and the second air duct 32. A diversion air duct is located on both sides of the connecting channel 33 and between the first air duct 31 and the second air duct 32. The diversion air duct 34 contains a swivel structure, which can control the airflow direction of the intermediate air outlet 14.

[0152] In different modes of the air conditioner 100, the airflow inside the air conditioner 100 has different flow directions to achieve different air output effects, and the air conditioner 100 can achieve better indoor temperature regulation.

[0153] Specifically, the first air outlet 11 is located above the second air outlet 12. Cold air tends to flow downwards indoors, resulting in lower temperatures at the bottom and higher temperatures at the top of the room. This is to ensure the uniformity of indoor temperature stratification under the control of the air conditioner 100 in this embodiment of the invention. Warm air tends to flow upwards indoors, resulting in lower temperatures at the bottom and higher temperatures at the top of the room.

[0154] The air conditioner 100 includes a first mode, a second mode, and a third mode. In the first mode, the first air outlet 11 is open, the second air outlet 12 is closed, and the middle air outlet 14 is open. The first centrifugal impeller 21, the second centrifugal impeller 22, and the third centrifugal impeller 23 are all turned on. The first mode is also the cooling mode.

[0155] 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 first air outlet 11. At this time, the second air outlet 12 is closed, and the airflow in the second air duct 32 is guided by the structure of the second air outlet 12 to the connecting channel 33. Through the connecting channel 33, it flows to the first air duct 31 and mixes with the airflow in the first air duct 31. The mixed airflow continues to flow along the first air duct 31 and is blown to the outside through the first air outlet 11. Since the first air outlet 11 is located at the top, in the cooling mode, the middle air outlet 14 is opened, and the louver structure in the split air duct 34 swings upward so that the air outlet 14 blows air upward. Thus, 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.

[0156] Furthermore, in the second mode, the first air outlet 11 is closed, the second air outlet 12 is open, and the middle air outlet 14 is open, while the first centrifugal impeller 21, the second centrifugal impeller 22, and the third centrifugal impeller 23 are all turned on. The second mode is also the heating mode.

[0157] 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 second air outlet 12. At this time, the first air outlet 11 is closed, and the airflow in the first air duct 31 is blocked by the structure of the first air outlet 11 and guided to the connecting channel 33. The airflow flows to the second air duct 32 through the connecting channel 33 and mixes with the airflow in the second air duct 32. The mixed airflow continues to flow along the second air duct 32 and is blown to the outside through the second air outlet 12. Since the second air outlet 12 is located at the bottom, in the heating mode, the middle air outlet 14 is opened, and the swaying structure in the diversion air duct 34 swings downward so that the air outlet 14 blows downward. Thus, 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] Furthermore, in the third mode, both the first air outlet 11 and the second air outlet 12 are open or partially open, and the first centrifugal impeller 21, the second centrifugal impeller 22, and the third centrifugal impeller 23 are all activated. The third mode is also known as the full-area air outlet mode.

[0159] The all-area air outlet mode is designed to meet the user's need for multi-directional airflow. In this mode, the air conditioner 100 can control the first air outlet 11, the second air outlet 12, and the middle air outlet 14 on the casing to simultaneously send air out. At this time, the first centrifugal impeller 21 sends air to the first air outlet 11 through the first air duct 31 to meet the user's need for airflow from above. The second centrifugal impeller 22 sends air to the second air outlet 12 through the second air duct 32 to meet the user's need for airflow from below. The middle third centrifugal impeller 23 sends air to the third air outlet through the diversion air duct 34. The oscillating blade structure in the diversion air duct 34 swings to a horizontal position.

[0160] Due to the connection channel 33, when one of the first air outlet 11 and the second air outlet 12 is closed, the airflow from the centrifugal impeller 2 corresponding to the closed air outlet can be guided to the other open air outlet. When the air outlet direction of the air conditioner 100 is controlled by opening and closing the first air outlet 11 or the second air outlet 12, the air volume generated by the corresponding centrifugal impeller 2 will not be lost, thus ensuring the air volume of the air conditioner 100.

[0161] Reference Figures 4-6 Multiple centrifugal impellers 2 are coaxially arranged and driven by the same motor. In this case, multiple centrifugal impellers 2 can be driven simultaneously by one motor, which simplifies the structure of the air conditioner 100, reduces production costs, ensures that the rotation speed of each centrifugal impeller 2 is the same, and the air volume at the outlet of each centrifugal impeller 2 is uniform, thereby improving the comfort of the air outlet effect of the air conditioner 100.

[0162] In other embodiments, the multiple centrifugal impellers 2 can be driven by multiple motors. For example, a motor can be set above the multiple centrifugal impellers 2 to drive one or more centrifugal impellers 2 above, and a motor can be set below the multiple centrifugal impellers 2 to drive one or more centrifugal impellers 2 below. By controlling the speed of multiple motors according to different needs, different air outlet effects can be achieved to meet different user needs.

[0163] like Figure 5 , Figure 6 and Figure 9 As shown, each centrifugal impeller 2 is a double-inlet centrifugal impeller 2. The air inlet 201 of the centrifugal impeller 2 is set vertically upward and downward, that is, the centrifugal impeller 2 is inlet from both sides of the axis. The airflow can be fully heat exchanged in the process of flowing to the centrifugal impeller 2, resulting in better cooling or heating effect.

[0164] A specific embodiment of the air conditioner 100 is described below with reference to the accompanying drawings.

[0165] like Figures 1-21 As shown, the air conditioner 100 includes: a casing and four coaxially arranged centrifugal impellers 2.

[0166] The four centrifugal impellers 2 are dual-inlet centrifugal impellers 2. The air inlets 201 of the centrifugal impellers 2 are vertically upward and downward, meaning that the centrifugal impellers 2 are axially inlet from both sides. The airflow can achieve sufficient heat exchange as it flows towards the centrifugal impellers 2, resulting in better cooling or heating effects. The four centrifugal impellers 2 are coaxially arranged and driven by the same motor. In this way, multiple centrifugal impellers 2 can be driven simultaneously by one motor, simplifying the structure of the air conditioner 100, reducing production costs, and ensuring that the rotational speed of each centrifugal impeller 2 is the same and the air volume at the outlet of each centrifugal impeller 2 is uniform, thereby improving the comfort of the air outlet effect of the air conditioner 100.

[0167] Four centrifugal impellers 2 are arranged sequentially in the vertical direction and housed within the casing, including a first centrifugal impeller 21 at the top, a second centrifugal impeller 22 at the bottom, and two third centrifugal impellers 23 located between the first and second centrifugal impellers 21 and 22. Each of the four centrifugal impellers 2 has an outlet, capable of discharging air outwards.

[0168] The centrifugal impellers 2 work together to provide greater air volume and pressure to the outside world, and deliver air to a greater distance in the radial direction. Multiple centrifugal impellers 2 are arranged sequentially in the height direction, that is, in the axial direction of the centrifugal impellers 2. Airflow can be formed at various points in the axial direction, realizing long-distance air delivery in the axial direction.

[0169] The front side of the casing has a first air outlet 11, a middle air outlet 14, and a second air outlet 12 arranged in the height direction, wherein the first air outlet 11 is located above the second air outlet 12 and the middle air outlet 14, and the second air outlet 12 is located below the first air outlet 11 and the middle air outlet 14.

[0170] The first centrifugal impeller 21 at the top is configured to supply air to the first air outlet 11, the third centrifugal impeller 23 in the middle is configured to supply air to the middle air outlet 14, and the second centrifugal impeller 22 at the bottom is configured to supply air to the second air outlet 12. Thus, the air generated by the outlets of each centrifugal impeller 2 can be directly blown out through the air outlet, ensuring the wind speed and air volume of each air outlet and ensuring the air outlet distance of the air conditioner 100.

[0171] The housing includes a housing 1, a movable panel 15, and a switch panel 4. A first air outlet 11 and a second air outlet 12 are located on the front sidewall 101 of the housing 1. The movable panel 15 is configured such that when one of the first air outlet 11 and the second air outlet 12 is closed, the other is in an open state. That is, the movable panel 15 can move between a first position where the second air outlet 12 is closed and the first air outlet 11 is open, and a second position where the first air outlet 11 is closed and the second air outlet 12 is open.

[0172] The movable panel 15 can slide up and down relative to the housing 1. When the movable panel 15 slides down to its lowest limit position, it is in the first position, which is the position where the second air outlet 12 is closed and the first air outlet 11 is open. When the movable panel 15 slides up to its highest limit position, it is in the second position, which is the position where the second air outlet 12 is open and the first air outlet 11 is closed. In some embodiments, the movable panel 15 can also slide to an intermediate position between the first and second positions, which is the position where the first air outlet 11 and the second air outlet 12 are opened or partially opened simultaneously. In this case, the air conditioner 100 vents air from both the top and bottom, which can meet the needs of the air conditioner 100's all-area air outlet mode.

[0173] The housing has a first air duct 31 connecting the first air outlet 11 and the first centrifugal impeller 21, and a second air duct 32 connecting the second air outlet 12 and the second centrifugal impeller 22. The front side of the housing has a recessed groove 16 that extends upward to the first air duct 31 and downward to the second air duct 32. A movable panel 15 covers the groove 16. During the movement of the movable panel 15 between the first position and the second position, it always covers the outside of the groove 16, and together with the groove 16, defines a connecting channel 33. The connecting channel 33 connects the first air duct 31 and the second air duct 32.

[0174] The casing has central air outlets 14 on both the left and right sides, and at least two split air ducts 34 inside the casing to direct the airflow generated at the outlet of the centrifugal impeller 2 to the central air outlets 14 on the left and right sides respectively. The central air outlets 14 on the left and right sides of the casing can deliver air to the left and right sides of the air conditioner 100 respectively, so that the air conditioner 100 can deliver air in all directions, ensuring that the air conditioner 100 can deliver air evenly to the room.

[0175] The intermediate cavity defined between the two branch air ducts 34 is also formed as a connecting channel 33. The connecting channel 33 is provided with a drive component for the movable panel 15. By placing the second drive device in the intermediate cavity defined between the two branch air ducts 34, the overall structure of the air conditioner 100 is made more compact, and the overall volume of the air conditioner 100 is reduced.

[0176] The diversion duct 34 is equipped with a sway vane structure, which can control the airflow direction of the middle air outlet 14.

[0177] In different modes of the air conditioner 100, the airflow inside the air conditioner 100 has different flow directions to achieve different air output effects, and the air conditioner 100 can achieve better indoor temperature regulation.

[0178] Specifically, the first air outlet 11 is located above the second air outlet 12. Cold air tends to flow downwards indoors, resulting in lower temperatures at the bottom and higher temperatures at the top of the room. This is to ensure the uniformity of indoor temperature stratification under the control of the air conditioner 100 in this embodiment of the invention. Warm air tends to flow upwards indoors, resulting in lower temperatures at the bottom and higher temperatures at the top of the room.

[0179] The air conditioner 100 includes a first mode, a second mode, and a third mode. In the first mode, the first air outlet 11 is open, the second air outlet 12 is closed, and the middle air outlet 14 is open. The first centrifugal impeller 21, the second centrifugal impeller 22, and the third centrifugal impeller 23 are all turned on. The first mode is also the cooling mode.

[0180] 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 first air outlet 11. At this time, the second air outlet 12 is closed, and the airflow in the second air duct 32 is guided by the structure of the second air outlet 12 to the connecting channel 33. Through the connecting channel 33, it flows to the first air duct 31 and mixes with the airflow in the first air duct 31. The mixed airflow continues to flow along the first air duct 31 and is blown to the outside through the first air outlet 11. Since the first air outlet 11 is located at the top, in the cooling mode, the middle air outlet 14 is opened, and the louver structure in the split air duct 34 swings upward so that the air outlet 14 blows air upward. Thus, 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.

[0181] Furthermore, in the second mode, the first air outlet 11 is closed, the second air outlet 12 is open, and the middle air outlet 14 is open, while the first centrifugal impeller 21, the second centrifugal impeller 22, and the third centrifugal impeller 23 are all turned on. The second mode is also the heating mode.

[0182] 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 second air outlet 12. At this time, the first air outlet 11 is closed, and the airflow in the first air duct 31 is blocked by the structure of the first air outlet 11 and guided to the connecting channel 33. The airflow flows to the second air duct 32 through the connecting channel 33 and mixes with the airflow in the second air duct 32. The mixed airflow continues to flow along the second air duct 32 and is blown to the outside through the second air outlet 12. Since the second air outlet 12 is located at the bottom, in the heating mode, the middle air outlet 14 is opened, and the swaying structure in the diversion air duct 34 swings downward so that the air outlet 14 blows downward. Thus, 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.

[0183] Furthermore, in the third mode, both the first air outlet 11 and the second air outlet 12 are open or partially open, and the first centrifugal impeller 21, the second centrifugal impeller 22, and the third centrifugal impeller 23 are all activated. The third mode is also known as the full-area air outlet mode.

[0184] The all-area air outlet mode is designed to meet the user's need for multi-directional airflow. In this mode, the air conditioner 100 can control the first air outlet 11, the second air outlet 12, and the middle air outlet 14 on the casing to simultaneously send air out. At this time, the first centrifugal impeller 21 sends air to the first air outlet 11 through the first air duct 31 to meet the user's need for airflow from above. The second centrifugal impeller 22 sends air to the second air outlet 12 through the second air duct 32 to meet the user's need for airflow from below. The middle third centrifugal impeller 23 sends air to the third air outlet through the diversion air duct 34. The oscillating blade structure in the diversion air duct 34 swings to a horizontal position.

[0185] Due to the connection channel 33, when one of the first air outlet 11 and the second air outlet 12 is closed, the airflow from the centrifugal impeller 2 corresponding to the closed air outlet can be guided to the other open air outlet. When the air outlet direction of the air conditioner 100 is controlled by opening and closing the first air outlet 11 or the second air outlet 12, the air volume generated by the corresponding centrifugal impeller 2 will not be lost, thus ensuring the air volume of the air conditioner 100.

[0186] A sealing plate is also provided at the middle air outlet 14 to close the middle air outlet 14 when the air conditioner 100 is turned off.

[0187] The switch panel 4 is used to open or close the first air outlet 11. When the air conditioner 100 is turned off, the switch panel 4 closes the first air outlet 11. When the air conditioner 100 is turned off, the movable panel 15 is in the second position. When the air conditioner 100 is turned off, the switch panel 4 and the movable panel 15 can jointly seal the front air outlet area of ​​the housing 1. When the air conditioner 100 is turned off, the surface of the air conditioner 100 is flat, ensuring the aesthetics of the air conditioner 100 and preventing external dust from entering.

[0188] When the air conditioner 100 is turned on, the switch panel 4 opens the first air outlet 11 to avoid affecting the movement path of the movable panel 15. The first air outlet 11 opens as the switch panel 4 moves, and the air conditioner 100 then controls the air outlet mode by controlling the movable panel 15. Only when the switch panel 4 moves to the position where the corresponding air outlet is open can the movable panel 15 move freely between the first position and the second position.

[0189] When the air conditioner 100 is turned on, the switch panel 4 opens the first air outlet 11 and moves to the inside of the front side wall 101 of the housing 1 to avoid obstructing the movement path of the movable panel 15 and improve the aesthetics of the air conditioner 100 during operation. When the air conditioner 100 is turned off and the first air outlet 11 is closed, the switch panel 4 is flush with the front side wall 101 of the housing 1 and also flush with the movable panel 15 to ensure that the front surface of the air conditioner 100 is flat and aesthetically pleasing when it is turned off, and that external dust does not easily accumulate.

[0190] The housing 1 is provided with a guide groove 17, and the switch panel 4 is provided with a guide post 41. The guide post 41 and the guide groove 17 are slidably engaged. The switch panel 4 moves under the guidance of the guide groove 17 to ensure the stability of the switch panel 4.

[0191] 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 panel 4 closes the corresponding air outlet. The front of the air conditioner 100 is the side of the switch panel 4 away from the centrifugal fan 2, and the rear of the air conditioner 100 is the side of the switch panel 4 facing the centrifugal fan 2.

[0192] Specifically, when the corresponding air outlet is opened, the switch panel 4 first moves backward a certain distance so that the switch panel 4 and the front side wall 101 of the housing 1 change from being on the same plane to a state where the front side wall 101 of the housing 1 is in front and the switch panel 4 is behind, so that the switch panel 4 can be subsequently stored inside the housing 1, behind the front side wall 101 of the housing 1.

[0193] In some embodiments, refer to Figure 7The extension direction of the front guide portion 171 of the guide groove 17 is inclined forward in the direction close to the movable panel 15. Therefore, while driving the switch panel 4 to move away from the movable panel 15, the switch panel 4 will also move rearward under the guidance of the guide groove 17. At the same time as driving the switch panel 4 to move closer to the movable panel 15, the switch panel 4 will also move from the rear to the front side, which is on the same plane as the front side wall 101 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.

[0194] The air conditioner 100 also includes a first drive component 5, which includes a first mounting box 57, two first drive motors, and a first transmission assembly. The first mounting box 57 is fixedly disposed on the front side wall 101 of the housing 1. The first transmission assembly includes a first moving rack and two sets of gears, the gear sets including a first gear 54, a second gear 55, and a third gear 56.

[0195] 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, the third gear 56 meshes with the first moving rack, and the first moving rack is connected to the switch panel 4 through the connecting assembly 53.

[0196] 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.

[0197] 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 panel 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 panel 4 to move.

[0198] 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.

[0199] 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 panel 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 panel 4 through the groove wall of the second groove 42, driving the switch panel 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 panel 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.

[0200] When the switch panel 4 moves away from or towards the first moving member 52 under the guidance of the guide groove 17, since the switch panel 4 and the first moving member 52 are always parallel during the movement, the angle between the connector 533 and the switch panel 4 increases during the movement of the switch panel 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.

[0201] As the switch panel 4 moves toward the first moving member 52, the angle between the connector 533 and the switch panel 4 decreases, the second mating shaft 532, which is fixedly connected to the connector 533, rotates relative to the second groove 42, the angle between the connecting component 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 connector 533, rotates relative to the first groove 521.

[0202] The first mating shaft 531 is disposed between the first groove 521 and the anti-detachment member 6, meaning 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 and be confined within the first groove 521. The second mating shaft 532 is disposed between the second groove 42 and the anti-detachment member 6, meaning 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 and be confined within the second groove 42.

[0203] The air conditioner 100 also includes a second drive component 7, which includes a second drive member 71 and a second transmission assembly. The second transmission assembly includes a second moving member 72. The second drive member 71 cooperates with the second transmission assembly to drive the second moving member 72 to reciprocate. The second moving member 72 cooperates with the movable panel 15.

[0204] The second driving component 71 includes two second driving motors respectively disposed on both sides of the second moving component 72. The second moving component 72 includes a second moving rack with teeth on both sides in the width direction. The second transmission component also includes two sets of second gears 55, which are symmetrically disposed on both sides of the second moving rack and respectively mesh with the teeth on both sides of the second moving rack.

[0205] The second gear set 55 includes a fourth gear 73, a fifth gear 74, and a sixth gear 75. The fourth gear 73 is fixedly connected to the drive shaft of the second drive motor. The fourth gear 73 meshes with the fifth gear 74. The fifth gear 74 and the sixth gear 75 are coaxially fixedly connected. The sixth gear 75 meshes with the second movable rack. Thus, the second movable rack moves vertically reciprocally under the driving force of the second drive member 71 transmitted by the second gear set 55. The movable panel 15 is fixedly connected to the second movable rack.

[0206] The second drive component 7 also includes a second mounting box 76, which is fixedly connected to the housing. In some embodiments, the second mounting box 76 is fixedly disposed in the groove 16.

[0207] The second mounting box 76 includes a second guide rail 77 extending from inside the second mounting box 76 to outside the second mounting box 76. The movable panel 15 moves under the guidance of the second guide rail 77. A second movable rack is vertically movable and guides the second guide rail 77. A second gear set 55 is rotatably disposed inside the second mounting box 76. A second drive member 71 is fixedly disposed outside the second mounting box 76, and the drive shaft of the second drive member 71 passes through the second mounting box 76 and is fixedly connected to the fourth gear 73 in the second gear set 55 disposed inside the second mounting box 76.
