[0050] The invention provides a vortex ring generating device.

[0051] In the embodiment of the present invention, Figures 1 to 3As shown, the vortex ring generating device 100 includes a housing 110, an airflow driving component 120, a driving device 130 and a reset member 140. The housing 110 includes a wind tube 111 and a flow collecting member 112. One end of the wind tube 111 is provided with a first air outlet 10. The flow collecting member 112 is installed on the first air outlet 10. The flow collecting member 112 is provided with an air supply port 30 connected to the wind tube 111. The air flow area of ​​the air supply port 30 is smaller than the air flow area of ​​the first air outlet 10. The airflow driving component 120 is movably arranged in the housing 110 to periodically drive the airflow to be blown out from the air supply port 30. The driving device 130 includes a driving member 131 and a flexible belt 132. One end of the flexible belt 132 is fixed to the airflow driving component 120, and the other end is fixed to the driving member 131. The driving member 131 is used to drive the flexible belt 132 to drive the airflow driving component 120 to move toward a side away from the air supply port 30. One end of the reset member 140 is connected to the airflow pushing component 120 , and the other end is connected to the housing 110 , so as to drive the airflow pushing component 120 to reset and move toward a side close to the air supply port 30 .

[0052] In this embodiment, the inner cavity of the shell 110 forms a vortex ring air duct, and the shape of the shell 110 can be a straight cylinder or a bent cylinder, and its cross-section can be rectangular, circular, elliptical, polygonal, or irregular, which are not specifically limited here. The overall shape of the vortex ring air duct and its cross-sectional shape can be selected according to the use requirements, which are not specifically limited here. The overall shape of the airflow driving component 120 is roughly compatible with the shape of the inner cavity of the shell 110, and the size is slightly smaller than the cross-sectional size of the inner cavity of the shell 110, so that the airflow driving component 120 can move along its axial direction in the shell 110. The airflow driving component 120 can specifically move axially in the wind tube 111. The airflow driving component 120 can be a piston, a push plate, or a combination of a push plate and a film arranged on the periphery of the push plate. It only needs to be able to push the airflow in the shell 110 so that the air supply port 30 blows out a vortex ring. The structure of the airflow driving component 120 is not specifically limited here. In order to facilitate the airflow to push the assembly 120 to move toward the side away from the air supply port 30 , a ventilation port may be provided on the bottom wall of the air cylinder 111 or on a side wall adjacent to the bottom wall.

[0053] The shapes of the first air outlet 10 and the air supply outlet 30 may be circular, rectangular, elliptical, polygonal, etc. The wind tube 111 is roughly cylindrical. In one embodiment, the collector 112 is a collector hood, which is gradually tapered from the air outlet to the air supply outlet 30. The cross-sectional shape of the collector hood may be circular, elliptical, rectangular, etc. In order to reduce wind resistance, the collector hood is roughly cylindrical. By gradually tapering the collector hood from the air outlet to the air supply outlet 30, the collector hood can collect the wind sent out from the air outlet, and make the generation and blowing of the vortex ring smoother.

[0054] In another embodiment, the current collecting member 112 is a current collecting plate, which is installed on the first air outlet 10, and an air supply port 30 is opened on the current collecting plate. The current collecting plate can be a plate covering the first air outlet 10, and by opening an air supply port 30 that is smaller than the air outlet on the current collecting plate, when the airflow blows out from the air outlet to the air supply port 30, due to the partial blocking effect of the current collecting plate, the airflow blown out of the air supply port 30 can be in the shape of a vortex ring. And the current collecting plate has a simple structure, and is easy to manufacture and process. In other embodiments, the current collecting member 112 can also be formed by enclosing several plates, and by setting the air supply port 30 on one of the plates, the formation of a vortex ring can also be achieved. The current collecting member 112 can also be formed by a combination of a current collecting plate and a current collecting cover,

[0055] The current collecting part 112 and the wind tube 111 can be integrally formed or separately formed. It can be understood that when the current collecting part 112 and the wind tube 111 are separately formed, the current collecting part 112 and the wind tube 111 are sealed and connected. When the collecting cover and the wind tube 111 are integrally formed, a virtual dividing line is divided by the junction of the wind tube 111 and the current collecting part 112. One side of the dividing line is the wind tube 111, and the other side is the current collecting part 112, and the air outlet of the wind tube 111 is formed at the dividing line. Undoubtedly, the air flow area of ​​the air outlet is larger than the air flow area of ​​the air supply port 30 of the current collecting part 112. The extension direction of the outer wall surface of the current collecting part 112 and the wind tube 111 can be consistent, that is, the length extension line of the outer wall surface of the two is a straight line. At this time, the vortex ring air supply part is a complete shape without a transfer line. The extension directions of the outer wall of the current collecting member 112 and the wind tube 111 may be inconsistent, that is, the length extension lines of the outer walls of the two are arranged at an angle. In this case, a transfer line will be formed at the connection between the current collecting member 112 and the wind tube 111.

[0056] By making the wind passing area of ​​the air supply port 30 smaller than the wind passing area of ​​the first air outlet 10, part of the airflow flowing from the first air outlet 10 to the air supply port 30 will flow along the inner wall surface of the collector 112, and then flow out from the periphery of the air supply port 30, and the other part of the airflow will flow out from the middle of the air supply port 30. The part of the airflow flowing out from the edge of the air supply port 30 is defined as the edge airflow, and the airflow flowing out from the middle of the air supply port 30 is positioned as the middle airflow. Then, the edge airflow is subject to the resistance of the inner wall surface of the collector 112. Compared with the middle airflow, the flow rate is lower. This difference in flow rate will cause vortex ring airflow when the airflow flows out of the air supply port 30. Under the same air volume, the vortex ring air supply method can realize directional, fixed-point and long-distance air supply. In addition, the vortex ring exchanges heat with the surrounding air during the transmission process, and the temperature difference between the vortex ring temperature and the surrounding air temperature is not large, which ensures that the vortex ring will not produce obvious overcooling or overheating when blowing on the human body, thereby improving comfort.

[0057] It is understandable that the length of the flexible belt 132 should be greater than the moving stroke of the airflow pushing component 120, so that when the airflow pushing component 120 is closest to the air outlet 30, the airflow pushing component 120 can be pulled to gradually move in the direction away from the air outlet 30. The flexible belt 132 refers to a belt-like structure that can be easily deformed but not easily destroyed. The material of the flexible belt 132 can be a cloth material such as nylon, cotton, fiber, a plastic material such as polyvinyl chloride, polyethylene, polypropylene, polyester, a rubber material, etc., or it can be formed by splicing or mixing the above materials. In order to further improve the transmission effect, the flexible belt 132 can also be a synchronous belt. Then the transmission is more accurate and stable, and has the ability to buffer and reduce vibration, thereby further reducing noise. One end of the flexible belt 132 can be fixed to the airflow pushing component 120 by welding, clamping, screw connection, bonding, etc.

[0058] The driving member 131 can be a driving cylinder, a driving motor, etc. The driving motor has the advantages of small size and easy control. The following is an exemplary description of the driving motor as an example. The flexible belt 132 can be directly wound on the driving shaft of the driving motor, or the flexible belt 132 can be fixed on the wire wheel 133 by setting a wire wheel 133 connected to the driving motor, thereby driving the flexible belt 132 to be wound on the wire wheel 133. The reset member 140 can be a compression spring. At this time, one end of the compression spring is connected to the airflow driving component 120, and the other end is connected to the housing 110. When the airflow driving component 120 moves to a side away from the air supply port 30 under the traction of the flexible belt 132, the compression spring is compressed. When the driving motor is powered off, the compression spring elastically recovers, thereby driving the airflow driving component 120 to move quickly to a side close to the air supply port 30, thereby pushing out the vortex ring airflow. The reset member 140 can also be two magnetic members that repel each other. At this time, one magnetic member is arranged on the airflow driving component 120, and the other is arranged on the bottom wall of the air cylinder 111. When the drive motor is powered on, the drive shaft of the drive motor rotates to wind the flexible belt 132, and the driving force is greater than the repulsive force between the two magnetic parts, thereby pulling the airflow push component 120 to a position away from the air outlet 30. When the drive motor is powered off, the driving force disappears, and the repulsive force of the two magnetic parts pushes the airflow push component 120 to a position close to the air outlet 30, thereby achieving rapid blowing of the vortex ring airflow from the air outlet 30.

[0059] When the vortex ring airflow needs to be pushed out, the driving member 131 drives the airflow pushing component 120 to move toward the side away from the air supply port 30 by winding and shrinking the flexible belt 132, and then the driving member 131 stops working, and drives the airflow pushing component 120 to move toward the side close to the air supply port 30 through the reset member 140, and the airflow pushing component 120 pushes the airflow to be blown out quickly from the air supply port 30, and by making the air flow area of ​​the air supply port 30 smaller than the air flow area of ​​the outlet, the vortex ring airflow can be blown out from the air supply port 30. This cycle is repeated, and the vortex ring airflow can be blown out from the air supply port 30 periodically.

[0060] The vortex ring generating device 100 of the present invention makes the wind passing area of ​​the air supply port 30 smaller than the wind passing area of ​​the first air outlet 10, and the airflow driving component 120 can be movably arranged in the housing 110 to periodically drive the airflow to be blown out from the air supply port 30, so that the vortex ring airflow can be periodically output from the air supply port 30, and directional, fixed-point and long-distance air supply can be achieved. At the same time, the flexible belt 132 is driven by the driving member 131 to drive the airflow driving component 120 to move toward the side away from the air supply port 30, and the reset member 140 drives the airflow driving component 120 to move toward the side close to the air supply port 30. Compared with the gear rack transmission mode, the rigid transmission is converted into a flexible transmission, which can effectively reduce the vibration noise and motion friction noise of the vortex ring generating device 100, thereby greatly improving the user experience.

[0061] In actual application, please refer to Figure 4 The driving device 130 also includes a wire wheel 133, one end of the flexible belt 132 is connected to the wire wheel 133, and the driving member 131 is connected to the wire wheel 133, so that when the driving member 131 is working, the wire wheel 133 is driven to wind the flexible belt 132, so as to drive the airflow pushing component 120 to move toward the side away from the air supply port 30, and when the driving member 131 stops working, the reset member 140 drives the airflow pushing component 120 to reset and move toward the side close to the air supply port 30, and drives the flexible belt 132 to extend from the wire wheel 133.

[0062] In the present embodiment, one end of the flexible belt 132 is fixed on the wire wheel 133, so that the flexible belt 132 can be wound around the winding surface of the wire wheel 133. The driving shaft of the driving motor is fixedly connected to the wire wheel 133, and then the wire wheel 133 is driven to rotate forward to wind the flexible belt 132 when the driving motor is powered on. When the driving motor is powered off, the wire wheel 133 can realize reverse rotation under a small driving force, so that the flexible belt 132 can be stretched out from the wire wheel 133 when the airflow push plate assembly is reset and moved. By setting the wire wheel 133, the flexible belt 132 is wound on the wire wheel 133, so that the winding of the flexible belt 132 is more regular, not easy to deviate, and thus the flexible belt 132 is easy to shrink and stretch. When the driving member 131 is working, the driving force is greater than the reset force of the reset member 140, so that the flexible belt 132 can be wound by the wire wheel 133 to pull the airflow push assembly 120 to move toward the side away from the air supply port 30. When the driving member 131 stops working, the driving force disappears, and the reset force of the reset member 140 drives the airflow pushing component 120 to quickly reset and move toward the side close to the air supply port 30, while driving the flexible belt 132 to stretch. In this way, the airflow pushing component 120 can achieve periodic reciprocating movement along the axial direction of the shell 110.

[0063] In one embodiment, if Figure 3 and Figure 6 As shown, the airflow push assembly 120 includes a push plate, one end of the flexible belt 132 is connected to the middle of the push plate, and the other end is tangent to the winding surface of the wire wheel 133. One end of the flexible belt 132 is fixedly connected to the middle of the push plate, so when the wire wheel 133 winds the flexible belt 132, it can pull the middle of the push plate, so that the force on the entire push plate is more uniform, and the movement of the push plate under the traction of the flexible belt 132 is more stable. The other end of the flexible belt 132 is connected to the wire wheel 133, and the flexible belt 132 is tangent to the winding surface of the wire wheel 133, so that the flexible belt 132 is wound around the winding surface of the wire wheel 133. In this way, the winding of the flexible belt 132 is more neat, and the moving stability of the push plate is further improved.

[0064] On the basis of the above embodiment, the vortex ring generating device 100 further includes a flexible belt fixing plate 150 , which is detachably mounted on the side of the push plate away from the air supply port 30 , and one end of the flexible belt 132 is fixed to the flexible belt fixing plate 150 .

[0065] In this embodiment, the flexible belt fixing plate 150 can be detachably connected to the push plate by means of screws, buckles, etc. The flexible belt 132 is fixed to the push plate by the flexible belt fixing plate 150, which facilitates the disassembly and assembly of the flexible belt 132 on the one hand, and makes the connection of the flexible belt 132 more stable on the other hand.

[0066] In one embodiment, please refer to Figure 4The wire wheel 133 includes a first half shell 40 and a second half shell 50 which are spliced ​​together along the radial direction, and one end of the flexible belt 132 is crimped between the first half shell 40 and the second half shell 50. It can be understood that the first half shell 40 and the second half shell 50 can be half of the entire wire wheel 133, or the size of one of the first half shell 40 and the second half shell 50 can be larger than half of the wire wheel 133, and the other can be smaller than half of the wire wheel 133. It is only necessary to splice the first half shell 40 and the second half shell 50 along the radial direction to form a complete wire wheel 133. The first half shell 40 and the second half shell 50 can be detachably spliced ​​by screws, buckles, magnetic attraction, etc. By crimping one end of the flexible belt 132 between the first half shell 40 and the second half shell 50, the connection stability of the flexible belt 132 and the wire wheel 133 is improved. In addition, one end of the flexible belt 132 is detachable, so that the replacement and adjustment of the flexible belt 132 is easy. The flexible band 132 may be crimped onto the joint surface of the first half shell 40 and the second half shell 50 .

[0067] On the basis of the above embodiment, further, a first concavoconvex part 41 is provided at the joint of the first half shell 40 toward the second half shell 50, a second concavoconvex part 51 matching the first concavoconvex part 41 is provided at the joint of the second half shell 50 toward the first half shell 40, and one end of the flexible belt 132 is crimped between the first concavoconvex part 41 and the second concavoconvex part 51. It can be understood that the middle part of the first half shell 40 and the second half shell 50 can be hollow or solid. Then the joint surface of the first half shell 40 and the second half shell 50 can be only the edge of the half shell, or can include the end surface of the middle part. By providing a first convex-concave portion 41 at the joint of the first half shell 40, and providing a second convex-concave portion 51 on the second half shell 50 to cooperate with the first convex-concave portion 41, one end of the flexible belt 132 is crimped between the first convex-concave portion 41 and the second convex-concave portion 51. After the first half shell 40 and the second half shell 50 are spliced ​​together, the contact surface and friction force between the flexible belt 132 and the half shells are increased, so that the flexible belt 132 is more tightly and firmly fixed on the pulley 133.

[0068] In one embodiment, if Figure 5 As shown, at least one end of the flexible belt 132 is provided with a reinforcing member 134 for fixing and installing the flexible belt 132. The reinforcing member 134 can be a hard structure such as a metal sheet or a plastic sheet. By providing the reinforcing member 134 at the end of the flexible belt 132, the strength and hardness of the end of the flexible belt 132 can be increased, so that it is easier to fix the end of the flexible belt 132 with the airflow driving component 120 and the wire wheel 133.

[0069] In one embodiment, please refer to Figure 6The vortex ring generating device 100 also includes a guide rod 160 extending along the axial direction of the wind tube 111, one end of the guide rod 160 is connected to the airflow pushing component 120, and the bottom wall of the wind tube 111 is provided with a guide hole for the other end of the guide rod 160 to pass through, the reset member 140 is a compression spring, and the extension direction of the guide rod 160 is consistent with the extension direction of the compression spring.

[0070] In this embodiment, the number of guide rods 160 can be one or more, and the number of compression springs can also be one or more. The number of guide rods 160 and the number of compression springs can be the same or different. The extension direction of the guide rod 160 is consistent with the extension direction of the compression spring, which can be completely consistent or have a deviation of less than or equal to 5 degrees. The guide rod 160 and the compression spring can be coaxially arranged or non-coaxially arranged. When coaxially arranged, the compression spring is sleeved on the periphery of the guide rod 160. In this way, the guide rod 160 not only guides the movement of the airflow driving component 120, but also guides the movement of the spring. The guide rod 160 can be fixed on the airflow driving component 120 by means of clamping, screw connection, bonding, etc. By setting a guide hole on the bottom wall of the air cylinder 111, when the airflow driving component 120 moves to the side away from the air supply port 30, the guide rod passes through the guide hole and provides a guiding effect for the movement of the airflow driving component 120.

[0071] In one embodiment, if Figure 2 and Figure 6 As shown, the airflow push component 120 includes a push plate, and the reset member 140 is a compression spring, one end of the compression spring is connected to the push plate, and the compression spring is arranged in the middle of the push plate. At this time, the compression spring can be only one, which is arranged in the middle of the push plate, so that when the compression spring pushes the push plate to reset and move, the overall force of the push plate is uniform, so that the reset movement is more stable. In another embodiment, there are multiple compression springs, and the multiple compression springs are distributed at intervals along the circumference of the push plate. The compression springs can be specifically 3, 4, 5, 6, etc. Multiple compression springs can be evenly and spaced along the circumference of the push plate, so that the force of the push plate is more uniform and the movement is more stable. By setting multiple compression springs, on the one hand, the return movement of the airflow push component 120 is more stable, and on the other hand, the return force is increased, so that the airflow push component 120 is pushed to move faster when it returns to the side close to the air supply port 30, so that the air supply distance of the vortex ring airflow is farther.

[0072] The present invention also provides an air conditioner indoor unit, see Figures 7 to 9The air conditioner indoor unit includes a housing 200 and a vortex ring generating device 100. The vortex ring generating device 100 is installed on the housing 200. The specific structure of the vortex ring generating device 100 refers to the above embodiment. Since the air conditioner indoor unit adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. The vortex ring generating device 100 can be specifically installed on the housing 200, or it can be installed in the housing 200. And the air duct of the vortex ring generating device 100 can be connected to the heat exchange air duct 210 in the housing 200, or it can be not connected. The air conditioner indoor unit can be an air conditioner indoor unit, a mobile air conditioner, a wall-mounted air conditioner indoor unit, a window unit, etc.

[0073] In one embodiment, if Figure 7 and Figure 8 As shown, the housing 200 has a heat exchange air duct 210 and a mounting port 220, the vortex ring generating device 100 is installed in the housing 200, and the air supply port 30 of the vortex ring generating device 100 is connected to the room through the mounting port 220;

[0074] The air conditioner indoor unit also includes a guide member 300 connected to the air supply port 30. The guide member 300 is arranged around the air supply port 30. A scattered air outlet channel 230 is formed between the outer wall surface of the guide member 300 and the inner wall surface of the installation port 220. The scattered air outlet channel 230 is connected to the heat exchange air duct 210. The guide member 300 is used to guide the airflow at the scattered air outlet channel 230 so that the airflow blown out of the scattered air outlet channel 230 deviates from the direction of the airflow blown out of the air supply port 30.

[0075] In this embodiment, the housing 200 can be integrally formed or separately formed, such as by splicing two sub-housings. The shape of the mounting port 220 of the housing 200 can be circular, elliptical, rectangular, polygonal, irregular, etc., and its shape is not specifically limited here. The shape of the mounting port 220 and the air supply port 30 can be the same or different. The air supply port 30 is connected to the room through the mounting port 220, and the current collecting member 112 can be arranged in the housing 110 so that the air supply port 30 corresponds to the vortex ring air outlet; the current collecting member 112 can also be abutted against the panel 240, that is, the vortex ring air outlet is connected to the air supply port 30; the current collecting member 112 can also be extended out of the panel 240 so that the air supply port 30 is placed outside the panel 240.

[0076] The guide member 300 is arranged around the air supply port 30, and the guide member 300 can be connected to the outer peripheral side wall of the collector 112. Through the action of the guide member 300, the airflow on the outer peripheral side wall of the collector 112 can be smoothly guided to the direction that deviates from the vortex ring airflow, thereby preventing the airflow blown out of the scattered wind outlet channel 230 from affecting the formation and air supply of the vortex ring airflow. The guide member 300 can be arranged in the housing 200, or it can be arranged to extend out of the housing 200, or it can be flush with the housing 200. When the guide member 300 is arranged in the housing 200, or it is flush with the housing 200, the radial dimension of the air outlet of the guide member 300 should be smaller than the radial dimension of the installation port 220, so that the scattered wind outlet channel 230 is smoothly formed between the outer wall surface of the guide member 300 and the inner wall surface of the installation port 220.

[0077] The guide member 300 and the flow collecting member 112 of the vortex ring generating device 100 can be integrally formed or separately formed. It should be noted that when the guide member 300 and the flow collecting member 112 are integrally formed, and the guide member 300 extends out of the housing 200, the radial dimension of the position of the guide member 300 corresponding to the mounting port 220 should be smaller than the radial dimension of the mounting port 220, so that a vortex ring air outlet is formed in the middle of the mounting port 220, and a dispersed air outlet channel 230 is formed around it. When the guide member 300 and the flow collecting member 112 are separately formed, and the guide member 300 extends out of the housing 200, and the flow collecting member 112 of the vortex ring generating device 100 is arranged in the housing 110. The air outlet 30 is located inside the panel 240. At this time, the radial dimension of the position of the air guide 300 corresponding to the mounting opening 220 should be smaller than the radial dimension of the mounting opening 220, so that the air guide 300 and the inner wall surface of the mounting opening 220 enclose a scattered air outlet channel 230. The airflow blown out of the scattered air outlet channel 230 can achieve windless air supply, which is softer and more comfortable.

[0078] In one embodiment, the guide member 300 is a guide tube, and a guide plate is provided at one end of the guide tube away from the air supply port 30. When the guide member 300 is arranged in the housing 200, the guide tube as a whole can be in a form of gradually expanding from the inside to the outside, or the guide plate can be in a form of gradually expanding from the inside to the outside. When the guide member 300 is extended out of the housing 200, the guide tube can be a straight tube, and the guide plate can also be arranged in a straight plate. In this way, the guide tube is connected to the collector 112, on the one hand, to guide the blowing of the vortex ring airflow, and on the other hand, to guide the airflow blown out of the scattered wind outlet channel 230 to the direction of the blowing of the vortex ring airflow away from the air supply port 30, so that the airflow blown out of the scattered wind outlet channel 230 will not affect the vortex ring airflow. At this time, the guide tube and the collector 112 can be arranged in an integrated manner without a transfer line, and the guide tube can also be arranged in a straight tube shape.

[0079] The heat exchange air duct 210 refers to the airflow entering from the main air inlet, which can be heat exchanged in this channel and then blown out from the second air outlet 251. A heat exchanger is provided in the heat exchange air duct 210, and a water receiving tray is provided under the heat exchanger for collecting and draining condensed water. The heat exchange air duct 210 can be directly formed by the enclosure of the outer shell 200, or it can be formed by the inner wall of the air duct in the outer shell 200. The cross-sectional shape of the outer shell 200 and the heat exchange air duct 210 can be circular, elliptical, rectangular, polygonal, etc. The extended shape of the heat exchange air duct 210 can be a straight cylinder type, or a bent type, etc.

[0080] The indoor air conditioner of the present invention is provided with a guide member 300 at the air supply port 30 of the vortex ring generating device 100, so that a scattered wind outlet channel 230 is formed between the outer wall surface of the guide member 300 and the inner wall surface of the mounting port 220, and the guide member 300 is used to guide the airflow blown out of the scattered wind outlet channel 230, so that the airflow blown out of the scattered wind outlet channel 230 deviates from the direction of the vortex ring airflow. In this way, the mounting port 220 opened on the panel 240 is fully utilized, so that the middle part of the mounting port 220 blows out the vortex ring airflow, and the heat exchange scattered wind airflow blows out around, and the airflow blown out of the scattered wind outlet channel 230 does not affect the vortex ring airflow. In this way, while the vortex ring accurately supplies air, the air supply distance is long, and the transmission efficiency is high, combined with the scattered wind outlet, the air supply area of ​​the entire indoor air conditioner is wider, the air supply distance is longer, and the heat exchange efficiency is high, so that the space temperature is more uniform and the comfort level is higher.

[0082] It can be understood that the two opposite side panels 250 connected to the two sides of the panel 240 refer to the side panels 250 located on the left and right sides of the entire housing 200. A second air outlet 251 can be opened on one of the side panels 250, or the second air outlet 251 can be opened on both side panels 250. In order to make the air outlet range wider and the air outlet area larger, it is preferred that the second air outlet 251 is opened on both side panels 250. The shape of the second air outlet 251 can be circular, elliptical, long strip, etc. In order to make the air outlet volume larger, it is preferably long strip. The panel 240 and the two side panels 250 can be integrally formed or separately formed. The housing 200 is also provided with an air inlet, and the air conditioner indoor unit also includes a heat exchange fan, which is installed in the heat exchange air duct 210. The heat exchange fan is used to drive sufficient airflow from the air inlet to flow through the heat exchange air duct 210 and blown out from the second air outlet 251. The air inlet can be provided on the panel 240 and / or the two side panels 250, and can also be provided on the rear panel 240 of the housing 200. By providing the second air outlet 251 on the side panel 250, the conventional air supply airflow will not affect the vortex ring airflow, and the air outlet area is wide, the air supply distance is long, and the air supply forms are diverse, while the airflow propagation efficiency is high, thereby improving the heat exchange efficiency of the room, making the temperature of the space more uniform, and thus improving the comfort. Conventional air supply and vortex ring air supply can be turned on at the same time or separately.
