Description

Technical Field

[0001] This application relates to the technical field of household appliances, and particularly to an air conditioner. Background Art

[0002] An air conditioner can simply and quickly bring a comfortable indoor temperature environment for people. Therefore, with the increasing living standards of people, an air conditioner has become an indispensable household appliance in people's daily lives.

[0003] An air conditioner generally includes an indoor unit and an outdoor unit. The outdoor unit is installed on the outdoor side, and the indoor unit is installed on the indoor side. An air outlet is provided on the indoor unit. When the air conditioner operates, the indoor unit of the air conditioner can send cold air or hot air into the room through the air outlet, thereby adjusting the temperature in the room.

[0004] In order to quickly adjust the temperature in the room, the existing indoor unit of an air conditioner generally has a deflector at the air outlet. Users can change the air outlet direction of the indoor unit of the air conditioner by rotating the deflector, thereby achieving the purpose of quickly adjusting the temperature in the room. However, the existing deflector can only adjust the air outlet direction within a small angle range, and the air outlet range of the indoor unit of the air conditioner is small. Summary of the Invention

[0005] This application provides an air conditioner for solving the problem of a small air outlet angle of the air conditioner.

[0006] An embodiment of this application provides an air conditioner, which includes a housing, a heat exchanger, a fan, and a wind guiding component. Among them, an air inlet and an air outlet are provided on the housing. The heat exchanger is arranged inside the housing, the fan is arranged inside the housing, and the wind guiding component is arranged at the air outlet. The air flow outside the housing is introduced into the housing through the air inlet by the operation of the fan and forms a heat exchange air flow through the heat exchanger. The heat exchange air flow is blown outwards from the air outlet under the driving of the operation of the fan.

[0007] The wind guiding component includes a plurality of guide vanes. The plurality of guide vanes are rotatably connected to the air outlet, and the rotation axes of the plurality of guide vanes coincide. The plurality of guide vanes have a first wind guiding position and a second wind guiding position. When the plurality of guide vanes are in the first wind guiding position, the plurality of guide vanes are arranged around the rotation axis for one week to form a wind guiding side wall. The wind guiding side wall is used to rotate clockwise or counterclockwise around the rotation axis so that the air flow blown out from the air outlet deflects along the rotation direction of the wind guiding side wall. When the plurality of guide vanes are in the second wind guiding position, the plurality of guide vanes are stacked to change the flow direction of the air flow passing through the plurality of guide vanes.

[0008] In the air conditioner provided by the embodiment of the present application, the external air flow can enter the interior of the housing from the air inlet and can be smoothly blown out through the air outlet. When the fan operates, the air flow outside the housing can be introduced into the interior of the housing from the air inlet and form a heat exchange air flow through the heat exchanger. The heat exchange air flow is blown outwards from the air outlet under the driving of the fan operation. When the air flow in the housing passes through a plurality of air guide plates in the first air guide position, the user can control the plurality of air guide plates to rotate clockwise or counterclockwise around the same rotation axis. At this time, the Magnus effect will occur to the air flow passing through the air guide side wall, that is, the flow velocity of the air flow around the air guide side wall will change, and then the air pressure around the air guide side wall will also change. As a result, a pressure difference will be formed between a part of the air flow around the air guide side wall and other parts of the air flow. Under the action of this pressure difference, the flow direction of the air flow passing through the plurality of air guide plates can be greatly deflected along the rotation direction of the air guide plates. The air outlet angle range of the air conditioner is greater than 90 degrees, and thus the air can be supplied to the whole house without dead angles.

[0009] When the plurality of air guide plates are in the second air guide position, that is, when the plurality of air guide plates are stacked, the flow direction of the air flow blown out from the interior of the housing can be changed under the guidance of the plurality of stacked air guide plates. Since the plurality of stacked air guide plates only need to be rotated to a specific position to make the air conditioner blow air in a specific direction when changing the air outlet direction of the air conditioner, and there is no need to continuously rotate the plurality of air guide plates, this enables the user to have multiple options when changing the air outlet direction of the air conditioner. In addition, since the plurality of stacked air guide plates have a relatively large thickness, when the air blown out by the air conditioner passes through the plurality of stacked air guide plates, condensation is not likely to occur on the air guide plates.

[0010] In some embodiments, the air guide assembly further includes a first support plate, a second support plate, a first connecting shaft, and a second connecting shaft. Along the direction of the rotation axis, the first support plate is located on one side of the plurality of air guide plates and is connected to one end of the plurality of air guide plates. Along the direction of the rotation axis, the second support plate is located on the other side of the plurality of air guide plates and is connected to the other end of the plurality of air guide plates. The first connecting shaft is located on the side of the first support plate away from the plurality of air guide plates, with one end connected to the first support plate and the other end rotatably connected to the housing. The second connecting shaft is located on the side of the second support plate away from the plurality of air guide plates, with one end connected to the second support plate and the other end rotatably connected to the housing.

[0011] In some embodiments, on one side of the first support plate close to the plurality of air guide plates, there is at least one first slide rail, and on one side of the second support plate close to the plurality of air guide plates, there is at least one second slide rail. The plurality of air guide plates include a first air guide plate and at least one second air guide plate. One end of the first air guide plate is connected to the first support plate, and the other end is connected to the second support plate. The cross-section of the first air guide plate is arc-shaped, and the cross-section of the first air guide plate is perpendicular to the rotation axis. One end of at least one second air guide plate is located in one first slide rail and is slidably connected to the first support plate, and the other end is located in one second slide rail and is slidably connected to the second support plate. The cross-section of the second air guide plate is arc-shaped, and the cross-section of the second air guide plate is perpendicular to the rotation axis.

[0012] In some embodiments, the air guide assembly further includes a first rack and a first driving motor. The first rack is disposed on one side of the second air guide plate close to the rotation axis and extends circumferentially along the rotation axis. The first driving motor is installed on the first support plate and meshes with the first rack.

[0013] In some embodiments, the air guide assembly further includes a second rack and a second driving motor. The second rack is disposed on one side of the second air guide plate close to the rotation axis and extends circumferentially along the rotation axis. The second driving motor is installed on the second support plate and meshes with the second rack.

[0014] In some embodiments, both ends of the second air guide plate have protruding portions, and the protruding portions are spherical. The protruding portion at one end of the second air guide plate is located in the first slide rail, and the protruding portion at the other end is located in the second slide rail.

[0015] In some embodiments, the radius of the first air guide plate is the same as the radius of the second air guide plate.

[0016] In some embodiments, the air conditioner further includes a plurality of third driving motors and a plurality of third racks. The first connecting shaft and the second connecting shaft are respectively rotatably connected to a third driving motor, and the third driving motor has an output shaft. The plurality of third racks are located inside the housing. Along the extending direction of the air outlet, the plurality of third racks are arranged at intervals. The third rack is connected to the housing, and the extending direction of the third rack is perpendicular to the extending direction of the air outlet. Each third rack meshes with the output shaft of a third driving motor.

[0017] In some embodiments, the air conditioner further includes a fourth driving motor. One end of the fourth driving motor is connected to the third driving motor, and the other end has an output shaft. The output shaft of the fourth driving motor is connected to the first connecting shaft to drive the air guide assembly to rotate.

[0018] In some embodiments, the number of the air guide assemblies is multiple. Along the extending direction of the air outlet, the multiple air guide assemblies are arranged side by side at the air outlet. Description of the Drawings

[0048] With the increasing improvement of people's living standards, more and more air conditioners are applied to people's daily lives. An air conditioner generally includes an indoor unit and an outdoor unit. The indoor unit is installed on the indoor side, and the outdoor unit is installed on the outdoor side. The indoor unit and the outdoor unit are connected through a refrigerant pipeline. When the air conditioner operates, the refrigerant forms a refrigeration or heating cycle among the indoor unit, the outdoor unit, and the refrigerant pipeline. The indoor unit located on the indoor side blows the air flow after heat exchange with the refrigerant into the room, thereby adjusting the indoor temperature.

[0049] The air outlet of the air conditioner directly affects the user experience. To increase the air outlet range of the air conditioner, an air conditioner is provided in the embodiments of this application. The air conditioner can be a wall-mounted air conditioner or a cabinet air conditioner. The following introduces it by taking the wall-mounted air conditioner as an example.

[0050] As Figure 1 shown, Figure 1 is one of the front views of the air conditioner 100 provided in the embodiments of this application. The air conditioner 100 provided in the embodiments of this application may include a housing 1, and an air inlet (not shown in the figure) and an air outlet 11 are provided on the housing 1.

[0051] It can be understood that an installation cavity 12 is formed inside the outer shell 1, and both the air inlet and the air outlet 11 are communicated with the installation cavity 12. The installation cavity 12 can provide an installation position for the components of the air conditioner 100, and the external air flow can enter the installation cavity 12 from the air inlet and can be smoothly blown out through the air outlet 11.

[0052] Exemplarily, as Figure 2 shown, Figure 2 is one of the sectional views of the air conditioner 100 provided by the embodiment of the present application. The outer shell 1 may include a front panel 13, a top grille 14, a rear panel 15, and a bottom plate 16 that are connected in sequence. Among them, the air outlet 11 is opened on the front panel 13 and the bottom plate 16. The rear panel 15 can be fixedly connected to the wall to facilitate the installation of the air conditioner 100. The opening on the top grille 14 can be used as an air inlet (not shown in the figure), and the external air can smoothly enter the installation cavity 12 through the air inlet.

[0053] To prevent impurities in the external air from entering the installation cavity 12, continue to refer to Figure 2 , the air conditioner 100 may further include a filter net (not shown in the figure). The filter net is connected to the top grille 14 and is used to filter impurities. In this way, the external air will be filtered by the filter net before entering the installation cavity 12, thereby preventing the impurities in the external air from entering the installation cavity 12 and damaging the air conditioner 100.

[0054] Continue to refer to Figure 2 , the air conditioner 100 may further include a heat exchanger 2 and a fan 3. The heat exchanger 2 and the fan 3 are both arranged inside the outer shell 1. The operation of the fan 3 can introduce the air flow outside the outer shell 1 into the interior of the outer shell 1 through the air inlet (not shown in the figure), and form a heat exchange air flow through the heat exchanger 2. The heat exchange air flow is blown outwards by the air outlet 11 under the driving of the operation of the fan 3.

[0055] To facilitate the heat exchange air flow in the outer shell 1 to be blown out from the air outlet 11, continue to refer to Figure 2 , the air conditioner 100 may further include a volute 4. The volute 4 is located inside the outer shell 1. The volute 4 forms an air duct 41. One end of the air duct 41 is communicated with the air outlet 11, and the fan 3 is located at the other end of the air duct 41. In this way, the air flow generated around the fan 3 during operation can smoothly enter the air duct 41 under the guidance of the volute 4 and be blown out from the air outlet 11.

[0056] To improve the structural strength of the outer shell 1, continue to refer to Figure 2 , multiple reinforcing ribs 5 may be further arranged inside the outer shell 1. One end of the reinforcing rib 5 is connected to the outer shell 1, and the other end is connected to the volute 4.

[0057] To prevent the condensed water generated on the heat exchanger 2 from dripping onto the circuit inside the air conditioner 100, continue to refer to Figure 2 , two water receiving trays 6 are further provided inside the housing 1. The two water receiving trays 6 are respectively arranged opposite to both ends of the heat exchanger 2. The water receiving tray 6 is connected to the volute 4, and the water receiving tray 6 is used to collect the condensed water generated on the heat exchanger 2. In this way, during the operation of the air conditioner 100, the condensed water generated on the heat exchanger 2 can be collected in the water receiving tray 6, thereby effectively reducing the possibility of the condensed water dripping onto the circuit inside the air conditioner 100 and improving the safety of the air conditioner 100.

[0058] To increase the air outlet range of the air conditioner 100, continue to refer to Figure 2 , the air conditioner 100 may further include a wind guiding assembly 7, and the wind guiding assembly 7 is arranged at the air outlet 11. The wind guiding assembly 7 may include a plurality of wind guiding plates 71. The plurality of wind guiding plates 71 are rotatably connected to the air outlet 11, and the rotation axes of the plurality of wind guiding plates 71 coincide. The plurality of wind guiding plates 71 have a first wind guiding position.

[0059] When the plurality of wind guiding plates 71 are in the first wind guiding position, the plurality of wind guiding plates 71 are arranged around the rotation axis for one week to form a wind guiding side wall 72. The wind guiding side wall 72 is used to rotate clockwise or counterclockwise around the rotation axis, so that the airflow blown out from the air outlet 11 deflects along the rotation direction of the wind guiding side wall 72.

[0060] When the airflow generated inside the housing 1 passes through the plurality of wind guiding plates 71 in the first wind guiding position, the user can control the plurality of wind guiding plates 71 to rotate clockwise or counterclockwise around the same rotation axis. At this time, the Magnus effect will occur to the airflow passing through the wind guiding side wall 72, that is, the flow velocity of the airflow around the wind guiding side wall 72 will change, and then the air pressure around the wind guiding side wall 72 will also change. As a result, a pressure difference will be formed between a part of the airflow around the wind guiding side wall 72 and other parts of the airflow. Under the action of this pressure difference, the flow direction of the airflow passing through the plurality of wind guiding plates 71 can deflect greatly along the rotation direction of the wind guiding plates 71. The air outlet angle range of the air conditioner 100 is greater than 90 degrees, and thus the whole house can be ventilated without dead corners.

[0061] Exemplarily, the shape of the cross section of the wind guiding side wall 72 in the direction perpendicular to the rotation axis can be circular, elliptical, etc., as long as the wind guiding side wall 72 can drive the airflow around it to flow, and thus can change the flow velocity of the airflow around it. It is not limited here.

[0062] It should be noted that the principle of the Magnus effect is as follows, as Figure 3 shown, Figure 3It is a schematic diagram of the principle of the Magnus effect. When the rotational angular velocity vector of a rotating object does not coincide with the object's flight velocity vector, a lateral force will be generated in the direction perpendicular to the plane formed by the rotational angular velocity vector and the translational velocity vector. The phenomenon that the flight trajectory of the object deflects under the action of this lateral force is called the Magnus effect. The reason why a rotating object can generate a force laterally is that the rotation of the object can drive the surrounding fluid to rotate, causing the fluid velocity on one side of the object to increase and the fluid velocity on the other side to decrease. According to Bernoulli's theorem, an increase in fluid velocity will lead to a decrease in pressure, and a decrease in fluid velocity will lead to an increase in pressure. This results in a pressure difference laterally on the rotating object and forms a lateral force. At the same time, since the lateral force is perpendicular to the direction of the object's motion, this force mainly changes the direction of the flight velocity, that is, it forms the centripetal force in the object's motion, thus causing a change in the flight direction of the object. Similarly, if the object is fixed and a rotational force is applied to keep it rotating, and at the same time a horizontal oncoming flow is applied, the rotating object will then change the direction of the horizontal oncoming flow.

[0063] Exemplarily, as Figure 4 shown, Figure 4 It is the second cross-sectional view of the air conditioner 100 provided by the embodiment of the present application. When the user controls the plurality of air deflector plates 71 to rotate clockwise, a pressure difference will be generated between the air flow blowing from the air outlet 11 to the periphery of the air guiding side wall 72 of the plurality of air deflector plates 71 and the air outside this air flow. This pressure difference forms a force acting along the X direction, and then under the action of this force acting along the X direction, the air flow deflects towards the X direction.

[0064] As Figure 5 shown, Figure 5 It is the third cross-sectional view of the air conditioner 100 provided by the embodiment of the present application. When the user controls the plurality of air deflector plates 71 to rotate counterclockwise, a pressure difference will be generated between the air flow blowing from the air outlet 11 to the periphery of the air guiding side wall 72 of the plurality of air deflector plates 71 and the air outside this air flow. This pressure difference will form a force acting along the Y direction, and then under the action of this force acting along the Y direction, the air flow deflects towards the Y direction.

[0065] It can be understood that the faster the rotational speed of the air guiding side wall 72 is, the greater the pressure difference generated between the air flow around the air guiding side wall 72 and the air outside this air flow will be. In this way, the deflection angle of the air flow after passing through the air guiding side wall 72 will be greater. Therefore, the plurality of air deflector plates 71 can enable the air conditioner 100 to have a larger air outlet range.

[0066] As Figure 6 shown, Figure 6This is the fourth cross-sectional view of the air conditioner 100 provided by the embodiments of the present application. The plurality of air guide plates 71 further have a second air guiding position. When the plurality of air guide plates 71 are in the second air guiding position, the plurality of air guide plates 71 are stacked, and the plurality of air guide plates 71 are used to change the flow direction of the air flow passing through the plurality of air guide plates 71.

[0067] When the plurality of air guide plates 71 are in the second air guiding position, that is, when the plurality of air guide plates 71 are stacked, the flow direction of the air flow blown out from the inside of the housing 1 can be changed under the guidance of the stacked air guide plates 71. Since the stacked air guide plates 71 only need to be rotated to a specific position when changing the air outlet direction of the air conditioner 100, the air conditioner 100 can blow air in a specific direction without continuously rotating the plurality of air guide plates 71, which provides the user with multiple options when changing the air outlet direction of the air conditioner 100. In addition, since the stacked air guide plates 71 have a relatively large thickness, condensation is not likely to occur on the air guide plates 71 when the air outlet of the air conditioner 100 passes through the stacked air guide plates 71.

[0068] In order to further adjust the air outlet direction of the air conditioner 100, in some embodiments, see Figure 1 , the air conditioner 100 may further include a plurality of air guide vanes 8, and the air guide vanes 8 are arranged in the air duct 41 ( Figure 2 ). Along the extension direction of the air outlet 11, the plurality of air guide vanes 8 are arranged at intervals in sequence and are rotatably connected to the volute 4 ( Figure 2 ). The air guide vanes 8 are used to adjust the air outlet direction of the air conditioner 100.

[0069] In this way, the air outlet direction of the air conditioner 100 can be adjusted by both the air guide assembly 7 and the air guide vanes 8. The air guide vanes 8 can further adjust the air outlet of the air conditioner 100, making the air outlet effect of the air conditioner 100 diverse.

[0070] In order to realize the rotation of the plurality of air guide plates 71, in some embodiments, as shown in Figure 7 , Figure 7 is the partial enlarged view of the position A in Figure 1 , the air guide assembly 7 may further include a first support plate 73 and a first connecting shaft 74. Along the direction of the rotation axis, the first support plate 73 is located on one side of the plurality of air guide plates 71 and is connected to one end of the plurality of air guide plates 71. Along the direction of the rotation axis, the first connecting shaft 74 is located on the side of the first support plate 73 away from the plurality of air guide plates 71. One end of the first connecting shaft 74 is connected to the first support plate 73, and the other end is rotatably connected to the housing 1.

[0071] As shown in Figure 8 , Figure 8 is Figure 1Partial enlarged view at B in the figure. The air guiding assembly 7 may further include a second support plate 75 and a second connecting shaft 76. Along the direction of the rotation axis, the second support plate 75 is located on the other side of the plurality of air guiding plates 71 and is connected to the other ends of the plurality of air guiding plates 71. Along the direction of the rotation axis, the second connecting shaft 76 is located on the side of the second support plate 75 away from the plurality of air guiding plates 71. One end of the second connecting shaft 76 is connected to the second support plate 75, and the other end is rotatably connected to the housing 1.

[0072] Since the first support plate 73 and the second support plate 75 are respectively connected to the two ends of the plurality of air guiding plates 71, the rotation of the first support plate 73 and the second support plate 75 can drive the plurality of air guiding plates 71 to rotate. In addition, since the first connecting shaft 74 and the second connecting shaft 76 are respectively connected to the first support plate 73 and the second support plate 75, the first support plate 73 and the second support plate 75 can be easily rotatably connected to the housing 1 through the first connecting shaft 74 and the second connecting shaft 76. By providing the first support plate 73, the second support plate 75, the first connecting shaft 74 and the second connecting shaft 76, the rotational connection between the plurality of air guiding plates 71 and the housing 1 is more easily achieved.

[0073] Of course, in some embodiments, connecting shafts may be provided at both ends of each air guiding plate 71, and each air guiding plate 71 is rotatably connected to the housing 1 through the connecting shafts at both ends.

[0074] To achieve the conversion of the plurality of air guiding plates 71 between the first air guiding position and the second air guiding position, in some embodiments, as Figure 9 shown, Figure 9 is the fifth cross-sectional view of the air conditioner 100 provided by the embodiment of the present application. The first support plate 73 ( Figure 7 ) has at least one first sliding rail 731 on the side close to the plurality of air guiding plates 71 ( Figure 7 ).

[0075] As Figure 10 shown, Figure 10 is the sixth cross-sectional view of the air conditioner 100 provided by the embodiment of the present application. The second support plate 75 ( Figure 8 ) has at least one second sliding rail 751 on the side close to the plurality of air guiding plates 71 ( Figure 8 ).

[0076] As Figure 11 shown, Figure 11 is the seventh cross-sectional view of the air conditioner 100 provided by the embodiment of the present application. The plurality of air guiding plates 71 may include a first air guiding plate 711 and at least one second air guiding plate 712. One end of the first air guiding plate 711 is connected to the first support plate 73 ( Figure 7 ), and the other end is connected to the second support plate 75 ( Figure 8) Connection. The cross-section of the first air deflector 711 is arc-shaped, and the cross-section of the first air deflector 711 is perpendicular to the rotation axis. One end of at least one second air deflector 712 is located in a first slide rail 731 and is slidably connected to the first support plate 73, and the other end is located in a second slide rail 751( Figure 10 ) and is slidably connected to the second support plate 75. The cross-section of the second air deflector 712 is arc-shaped, and the cross-section of the second air deflector 712 is perpendicular to the rotation axis.

[0077] By providing the first slide rail 731 and the second slide rail 751 on one side of the first support plate 73 and the second support plate 75 close to the plurality of air deflectors 71 respectively, the second air deflector 712 can slide relative to the first support plate 73 and the second support plate 75 through the first slide rail 731 and the second slide rail 751, so that the first air deflector 711 and the second air deflector 712 can be switched between the stacked or unfolded states, meeting the diverse usage needs of users. For the unfolded state of the first air deflector 711 and the second air deflector 712, please refer to Figure 11 , for the stacked state of the first air deflector 711 and the second air deflector 712, please refer to Figure 12 , Figure 12 This is the eighth cross-sectional view of the air conditioner 100 provided by the embodiment of the present application.

[0078] In addition, since the shapes of the cross-sections of the first air deflector 711 and the second air deflector 712 in the direction perpendicular to the rotation axis are arc-shaped, the first air deflector 711 and the second air deflector 712 are more likely to drive the surrounding air flow, and the sliding of the second air deflector 712 on the first support plate 73 and the second support plate 75 is more easily achieved.

[0079] Exemplarily, the number of the second air deflectors 712 can be two. Correspondingly, the number of the first slide rails 731 is also two, and the number of the second slide rails 751 is also two. Both ends of one of the second air deflectors 712 are slidably connected to a first slide rail 731 and a second slide rail 751 respectively, and both ends of the other second air deflector 712 are slidably connected to another first slide rail 731 and another second slide rail 751 respectively.

[0080] Of course, in some embodiments, the number of the second air deflectors 712 can also be one. Correspondingly, the number of the first slide rails 731 is also one, and the number of the second slide rails 751 is also one. When the number of the second air deflectors 712 is one, for the unfolded state of the first air deflector 711 and the second air deflector 712, please refer to Figure 13 , Figure 13 This is the ninth cross-sectional view of the air conditioner 100 provided by the embodiment of the present application. For the stacked state of the first air deflector 711 and the second air deflector 712, please refer to Figure 14 , Figure 14This is the tenth cross-sectional view of the air conditioner 100 provided by the embodiments of the present application.

[0081] Exemplarily, the first slide rail 731 can be composed of two spaced guiding plates. One end of the guiding plate is connected to the first supporting plate 73, and there is a gap between the two guiding plates. One end of the second air guiding plate 712 is located within the gap. The second slide rail 751 can also be composed of two spaced guiding plates. One end of the guiding plate is connected to the second supporting plate 75, and there is a gap between the two guiding plates. The other end of the second air guiding plate 712 is located within the gap.

[0082] Certainly, in some embodiments, a guiding block is provided on the side of the first supporting plate 73 close to the plurality of air guiding plates 71. One end of the guiding block is connected to the first supporting plate 73, and a groove is formed on the end surface of the other end. The guiding block with the groove forms the first slide rail 731, and one end of the second air guiding plate 712 is located within the groove. A guiding block is also provided on the side of the second supporting plate 75 close to the plurality of air guiding plates 71. One end of the guiding block is connected to the second supporting plate 75, and a groove is formed on the end surface of the other end. The guiding block with the groove forms the second slide rail 751, and the other end of the second air guiding plate 712 is located within the groove.

[0083] To realize the conversion between the first air guiding position and the second air guiding position of the first air guiding plate 711 and the second air guiding plate 712, in some embodiments, as Figure 11 shown, the air guiding assembly 7 can include a first rack 77 and a first driving motor 78. Among them, the first rack 77 is arranged on the side of the second air guiding plate 712 close to the rotation axis, and the first rack 77 extends circumferentially along the rotation axis. The first driving motor 78 is installed on the first supporting plate 73 ( Figure 7 ), and meshes with the first rack 77.

[0084] The first driving motor 78 can provide power, and then drive the second air guiding plate 712 to move through the first rack 77. In this way, the conversion of the plurality of air guiding plates 71 between the first air guiding position and the second air guiding position is more easily achieved.

[0085] Certainly, the air conditioner 100 can also adopt transmission methods such as crank-screw drive, direct motor drive, chain drive, crank-slider, etc. to provide driving force for the movement of the second air guiding plate 712, or adopt two or more of the above transmission methods to provide driving force for the movement of the second air guiding plate 712, which is not limited herein.

[0086] To improve the stability of the conversion of the plurality of air guiding plates 71 between the first air guiding position and the second air guiding position, in some embodiments, as Figure 15 shown, Figure 15FIG. 11 is a cross-sectional view of the air conditioner 100 provided by an embodiment of the present application. The air guiding assembly 7 may further include a second rack 79 and a second driving motor 791. The second rack 79 is disposed on a side of the second air guiding plate 712 close to the rotation axis, and the second rack 79 extends circumferentially along the rotation axis. The second driving motor 791 is mounted on the second support plate 75( Figure 8 ), and meshes with the second rack 79.

[0087] The second driving motor 791 can provide power, and then drive the second air guiding plate 712 to move through the second rack 79. In this way, both the first driving motor 78 and the second driving motor 791 can apply forces to the second air guiding plate 712, and the forces applied by the first driving motor 78 and the second driving motor 791 act on opposite ends of the second air guiding plate 712 respectively. As a result, the force received by the second air guiding plate 712 during movement is relatively uniform, and the stability of the plurality of air guiding plates 71 during conversion between the first air guiding position and the second air guiding position is higher.

[0088] It can be understood that gears may be fixedly connected to the output shafts of the first driving motor 78 and the second driving motor 791, and the first driving motor 78 and the second driving motor 791 are respectively meshed with the first rack 77 and the second rack 79 through the gears.

[0089] Exemplarily, the first driving motor 78 may be located on a side of the first support plate 73 close to the plurality of air guiding plates 71 and connected to the first support plate 73, and the second driving motor 791 may be located on a side of the second support plate 75 close to the plurality of air guiding plates 71 and connected to the second support plate 75.

[0090] Certainly, in some embodiments, referring to Figure 7 and Figure 8 , an avoidance hole 732 may be formed on the first support plate 73, and an avoidance hole 732 may also be formed on the second support plate 75. The first driving motor 78 is located on a side of the first support plate 73 away from the plurality of air guiding plates 71, and the output shaft of the first driving motor 78 passes through the avoidance hole 732 to mesh with the first rack 77. The second driving motor 791 is located on a side of the second support plate 75 away from the plurality of air guiding plates 71, and the output shaft of the second driving motor 791 passes through the avoidance hole 732 to mesh with the second rack 79. In this way, by disposing both the first driving motor 78 and the second driving motor 791 on sides of the first support plate 73 and the second support plate 75 away from the plurality of air guiding plates 71, the first driving motor 78 and the second driving motor 791 can dissipate heat more easily.

[0091] In order to relatively fix multiple air guide plates 71 in the first air guiding position or the second air guiding position, in some embodiments, the first driving motor 78 and the second driving motor 791 can be selected as motors with a self-locking function. When the second air guide plate 712 moves to the first air guiding position or the second air guiding position, the first driving motor 78 and the second driving motor 791 can firmly fix the second air guide plate 712 at this specific position.

[0092] Of course, in some embodiments, a convex structure and a concave structure can be respectively arranged between adjacent two air guide plates 71. When multiple air guide plates 71 are in the first air guiding position or the second air guiding position, the convex structure of one of the adjacent two air guide plates 71 can be clamped into the concave structure of the other air guide plate 71, thereby realizing the relative fixation of the positions between multiple air guide plates 71.

[0093] In order to reduce the frictional force suffered by the second air guide plate 712 when sliding in the first slide rail 731 and the second slide rail 751, in some embodiments, refer to Figure 11 , both ends of the second air guide plate 712 have convex portions 7121, and the convex portions 7121 are spherical. The convex portion 7121 at one end of the second air guide plate 712 is located in the first slide rail 731, and the convex portion 7121 at the other end is located in the second slide rail 751( Figure 10 )).

[0094] Since the portions of the second air guide plate 712 located in the first slide rail 731 and the second slide rail 751 are spherical convex portions 7121, the contact area of the spherical convex portions 7121 with the first slide rail 731 and the second slide rail 751 is small when sliding. Therefore, the frictional force suffered by the second air guide plate 712 when sliding in the first slide rail 731 and the second slide rail 751 is small, and the conversion between the first air guiding position and the second air guiding position of multiple air guide plates 71 is more flexible and labor-saving.

[0095] In order to improve the air guiding effect of the air guiding side wall 72 on the air flow, in some embodiments, continue to refer to Figure 11 , the radius of the first air guide plate 711 is the same as the radius of the second air guide plate 712. In this way, when multiple air guide plates 71 are in the first air guiding position, the shape of the cross section of the air guiding side wall 72 formed by the first air guide plate 711 and the second air guide plate 712 in the direction perpendicular to the rotation axis is circular. Thus, the air flow can easily flow around the air guiding side wall 72, which is more conducive to changing the flow velocity of the air flow around the air guiding side wall 72, and further more easily realizes the change of the air flow direction by the air guiding assembly 7, and the air guiding effect of the air guiding assembly 7 is better.

[0096] It can be understood that when the radii of the first air guide plate 711 and the second air guide plate 712 are the same, refer to Figure 9, the first slide rail 731 has a first bending portion 7311 at the end close to the first air deflector 711.

[0097] See Figure 10 , the second slide rail 751 has a second bending portion 7511 at the end close to the first air deflector 711.

[0098] Under the action of an external force, the second air deflector 712 can deform within an appropriate range and can recover its deformation when the external force is removed. When the second air deflector 712 slides along the first slide rail 731 and the second slide rail 751 and passes through the first bending portion 7311 and the second bending portion 7511, the second air deflector 712 can deform at the first bending portion 7311 and the second bending portion 7511. When the second air deflector 712 disengages from the first bending portion 7311 and the second bending portion 7511, the second air deflector 712 can recover its deformation. When multiple air deflectors 71 are in the first air guiding position or the second air guiding position, the second air deflector 712 does not contact the first bending portion 7311 and the second bending portion 7511.

[0099] In order to improve the air outlet effect of the air conditioner 100, in some embodiments, as Figure 7 and Figure 8 shown, the air conditioner 100 may further include a plurality of third driving motors 9 and a plurality of third racks 91. The first connecting shaft 74 and the second connecting shaft 76 are respectively rotationally connected to a third driving motor 9, and the third driving motor 9 has an output shaft. A plurality of third racks 91 are located inside the housing 1. Along the extension direction of the air outlet 11 ( Figure 1 ), the plurality of third racks 91 are arranged at intervals. The third rack 91 is connected to the housing 1, and the extension direction of the third rack 91 is perpendicular to the extension direction of the air outlet 11. Each third rack 91 meshes with the output shaft of a third driving motor 9.

[0100] Since the first connecting shaft 74 is connected to a third driving motor 9 and the second connecting shaft 76 is connected to a third driving motor 9, the third driving motor 9 can improve the power and thus drive the air guiding assembly 7 to move along the extension direction of the third rack 91. In this way, the user can change the position of the air guiding assembly 7 at the air outlet 11 and the rotation state of the air guiding assembly 7 according to different air usage requirements, thereby ensuring that the air conditioner 100 has a good air outlet effect in different air outlet modes, and the refrigeration or heating efficiency of the air conditioner 100 is relatively high.

[0101] Exemplarily, as Figure 16 shown, Figure 16This is the twelfth cross-sectional view of the air conditioner 100 provided by the embodiment of the present application. When multiple air deflector plates 71 are in the first air guiding position, the third driving motor 9 can drive the multiple air deflector plates 71 to move above the air outlet 11, and then the third driving motor 9 drives the air guiding side wall 72 to rotate clockwise. In this way, the upper part of the air flow blown out from the air outlet 11 can generate the Magnus effect under the guidance of the clockwise rotating air guiding side wall 72, so that this part of the air flow can achieve an upward effect, and the flow rate of this part of the air flow can also be increased under the drive of the air guiding side wall 72, that is, the air supply distance and the air outlet range of the air conditioner 100 are both increased.

[0102] In addition, as Figure 17 shown, Figure 17 This is the thirteenth cross-sectional view of the air conditioner 100 provided by the embodiment of the present application. When multiple air deflector plates 71 are in the first air guiding position, the third driving motor 9 can also drive the multiple air deflector plates 71 to move below the air outlet 11, and then the third driving motor 9 drives the air guiding side wall 72 to rotate counterclockwise. In this way, the lower part of the air flow blown out from the air outlet 11 can generate the Magnus effect under the guidance of the counterclockwise rotating air guiding side wall 72, so that this part of the air flow can achieve a downward effect. Since the downward flowing air is only a part of the air flow blown out from the air outlet 11, the air volume of this part of the air flow is small. When the downward flowing air blows on the user, the user can only feel the cool or warm feeling, and will not feel the stimulating wind feeling, and the user comfort is high. Since the upper part of the air flow blown out from the air outlet 11 is less affected by the air guiding side wall 72, the flow direction of this part of the air flow cannot be changed by the air guiding side wall 72 and will continue to blow out along the original flow direction, so as to achieve the effect of adjusting the temperature of the indoor environment. Therefore, the air conditioner 100 provided by the embodiment of the present application can perfectly achieve the effect of no wind feeling without losing the air volume.

[0103] As Figure 6 shown, when multiple air deflector plates 71 are in the second air guiding position, that is, when the multiple air deflector plates 71 are stacked, the third driving motor 9 can drive the multiple air deflector plates 71 to move above the air outlet 11, and the multiple air deflector plates 71 can be inclined downward. At this time, the air flow blown out from the air outlet 11 can be blown obliquely downward under the guidance of the multiple air deflector plates 71, so that the air conditioner 100 realizes downward carpet-like air supply.

[0104] As Figure 18 shown, Figure 18FIG. 14 is a cross-sectional view of the air conditioner 100 provided by an embodiment of the present application. When multiple air deflector plates 71 are stacked, the third drive motor 9 can also drive the multiple air deflector plates 71 to move below the air outlet 11, and the multiple air deflector plates 71 can be tilted upward. At this time, the air flow blown out from the air outlet 11 can be blown obliquely upward under the guidance of the multiple air deflector plates 71, so that the air conditioner 100 realizes upward sky curtain type air supply.

[0105] As Figure 19 shown, Figure 19 FIG. 15 is a cross-sectional view of the air conditioner 100 provided by an embodiment of the present application. When multiple air deflector plates 71 are stacked and the third drive motor 9 drives the multiple air deflector plates 71 to move below the air outlet 11, the multiple air deflector plates 71 can also be rotated to a horizontal position. At this time, the air flow blown out from the air outlet 11 can be blown horizontally under the guidance of the multiple air deflector plates 71, so that the air conditioner 100 realizes horizontal air supply.

[0106] Exemplarily, the third drive motor 9 can be a motor with a self-locking function. In this way, when the air deflector assembly 7 moves to a specific position in a certain air supply mode, the third drive motor 9 can firmly fix the air deflector assembly 7 at this specific position.

[0107] In order to keep the third rack 91 and the third drive motor 9 always engaged, in some embodiments, referring to Figure 19 FIG., the air conditioner 100 may further include multiple stoppers 92, and the multiple stoppers 92 are located inside the housing 1. Along the extending direction of the air outlet 11, the multiple stoppers 92 are arranged at intervals. A part of the stopper 92 is located on the side of the output shaft of the third drive motor 9 away from the third rack 91 and abuts against the output shaft of the third drive motor 9.

[0108] In this way, the stopper 92 can limit the separation of the output shaft of the third drive motor 9 from the third rack 91, ensuring that the output shaft of the third drive motor 9 and the third rack 91 can always be engaged, and further ensuring that the position of the air deflector assembly 7 at the air outlet 11 can be stably changed by the third drive motor 9.

[0109] In order to realize the rotation of the air deflector assembly 7, in some embodiments, as Figure 7 shown, the air conditioner 100 may further include a fourth drive motor 93. One end of the fourth drive motor 93 is connected to the third drive motor 9, and the other end has an output shaft. The output shaft of the fourth drive motor 93 is connected to the first connecting shaft 74 to drive the air deflector assembly 7 to rotate.

[0110] Since the first connecting shaft 74 is connected to the fourth driving motor 93, the fourth driving motor 93 can provide power for the rotation of multiple air guide plates 71. The user can change the deflection direction and angle of the air flow by controlling the rotation direction and speed of the fourth driving motor 93, thereby realizing various air outlet modes of the air conditioner 100.

[0111] The fourth driving motor 93 can be selected from a stepless variable speed motor, a stepping motor, an AC motor, a DC motor, etc.

[0112] In order to reduce the resistance suffered by the air guide assembly 7 during rotation, in some embodiments, as Figure 8 shown, the air conditioner 100 may further include a rotating bearing 94. The rotating bearing 94 is rotatably connected to the second connecting shaft 76, and one end of the rotating bearing 94 away from the second support plate 75 is connected to the third driving motor 9.

[0113] Since the friction coefficient of the rotating bearing 94 is extremely low, the second connecting shaft 76 of the air guide assembly 7 is connected to the third driving motor 9 through the rotating bearing 94, which can effectively reduce the resistance suffered by the air guide assembly 7 during rotation, making the rotation of the air guide assembly 7 easier to achieve.

[0114] In order to meet the various air use requirements of users, in some embodiments, as Figure 20 shown, Figure 20 FIG. 2 is a second front view of the air conditioner 100 provided by the embodiment of the present application. The number of air guide assemblies 7 is multiple. Along the extension direction of the air outlet 11, multiple air guide assemblies 7 are arranged side by side at the air outlet 11.

[0115] The user can control the multiple air guide assemblies 7 at the air outlet 11 to be in different air guide positions or operate in different rotation modes, so that the multiple air guide assemblies 7 can achieve different air supply modes in different regions of the air outlet 11, further improving the diversity of the air outlet of the air conditioner 100 and meeting the various use requirements of users.

[0116] Exemplarily, the number of the air guide assemblies 7 can be set to two. The two air guide assemblies 7 can enable the air conditioner 100 to have two different forms of air outlet at the same time, meeting the various use requirements of users.

[0117] It can be understood that when the air conditioner 100 has two air guide assemblies 7, the number of the third driving motors 9 and the third racks 91 is set to four. Two of the third driving motors 9 and the third racks 91 are respectively located at both ends of one air guide assembly 7, and the other two third driving motors 9 and the third racks 91 are respectively located at both ends of the other air guide assembly 7.

[0118] In order to reduce the risk of external debris entering the housing 1, in some embodiments, asFigure 19 As shown, the air conditioner 100 may further include a baffle 95. The baffle 95 is connected to the housing 1. Under the action of the driving mechanism and the transmission mechanism, the baffle 95 can open or close the air outlet 11.

[0119] In this way, when the air conditioner 100 is working, the baffle 95 opens the air outlet 11 under the action of the driving mechanism and the transmission mechanism. At this time, the air blown out by the air conditioner 100 can be blown out from the air outlet 11. When the air conditioner 100 is turned off, the baffle 95 closes the air outlet 11 under the action of the driving mechanism and the transmission mechanism. In this way, it can effectively prevent external sundries from entering the housing 1 and improve the service life of the air conditioner 100.

[0120] To facilitate the use of the air conditioner 100, in some embodiments, the air conditioner 100 may further include a controller. The controller stores parameters of various rotation states and various position states of the air guiding assembly 7 internally. The user can meet different usage requirements by retrieving different parameters in the controller.

[0121] Exemplarily, as Figure 21 shown, Figure 21 is the control logic diagram of the air conditioner 100 provided by the embodiment of the present application. After the air conditioner 100 is started, according to the user's own usage requirements, the user first adjusts the position state of the air guiding assembly 7 through the remote control, or the air conditioner 100 intelligently adjusts the position state of the air guiding assembly 7 according to the temperature of the indoor environment, and then the user adjusts the rotation state of the air guiding assembly 7 through the remote control. After the user sets the position state of the air guiding assembly 7 and the rotation state of the air guiding assembly 7 in the controller, the air conditioner 100 can operate according to this preset state to meet the specific needs of the user.

[0122] Of course, the user can also freely control the position of the air guiding assembly 7 and the rotation speed of the air guiding assembly 7, so that the air guiding assembly 7 can be located at any position of the air outlet 11 and rotate at any speed, thereby realizing the adjustment of the air outlet angle, divergence and the blowing distance of the air conditioner 100.

[0123] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
