Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and particularly relates to a vortex ring generating device, an indoor air conditioner, and an air conditioner. Background Art

[0002] In the existing air conditioner, the air flow after heat exchange is blown out through a conventional air outlet of the air conditioner. The air outlet mode is conventional air outlet, and the air flow coming out of the conventional air outlet is fixed. Its radiation range is short and narrow, and it is impossible to achieve large-range and long-distance air supply, reducing the user experience.

[0003] By setting a vortex ring generating device, long-distance air supply can be achieved. The vortex ring generating device can push out a vortex ring by using an air flow pushing component to squeeze the gas in the housing. Currently, there are methods such as the sliding of the edge of the air flow pushing component and the inner wall surface of the housing or the sliding guide of a guide rod. However, this method will generate relatively large resistance and noise.

Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B at the same time.

[0059] The present invention provides a vortex ring generating device 100.

[0060] In the embodiments of the present invention, as Figures 1 to 5As shown in the figure, the vortex ring generating device 100 includes a housing 110, an air flow pushing component 120, a roller component 130, and a driving device 140. The housing 110 includes a wind tunnel 111 and a flow collector 112. One end of the wind tunnel 111 is provided with an air outlet 111a, and the flow collector 112 is installed at the air outlet 111a. The flow collector 112 is provided with an air supply port 112a communicating with the wind tunnel 111, and the air passing area of the air supply port 112a is smaller than that of the air outlet 111a. The air flow pushing component 120 is movably arranged in the housing 110. The roller component 130 is installed on one of the air flow pushing component 120 and the housing 110 and is in rolling cooperation with the other of the air flow pushing component 120 and the housing 110, so that the air flow pushing component 120 can move axially along the housing 110. The driving device 140 is used to drive the air flow pushing component 120 to reciprocate in the housing 110 to periodically push the air flow to blow out from the air supply port 112a.

[0061] In this embodiment, the inner cavity of the housing 110 forms a vortex ring air duct. The shape of the housing 110 can be a straight cylinder shape, a bent cylinder shape, and its cross-section can be a rectangle, a circle, an ellipse, a polygon, a special shape, etc., which are not specifically limited herein. The overall shape and cross-sectional shape of the vortex ring air duct can be selected according to the use requirements, which are not specifically limited herein. The overall shape of the air flow pushing component 120 is generally adapted to the shape of the inner cavity of the housing 110, and the size is slightly smaller than the cross-sectional size of the inner cavity of the housing 110, so that the air flow pushing component 120 can move axially in the housing 110. Specifically, the air flow pushing component 120 can move axially in the wind tunnel 111. The air flow pushing component 120 can be a piston, a push plate, or can be composed of a push plate and a film arranged on the periphery of the push plate, as long as it can push the air flow in the housing 110 to make the vortex ring blow out from the air supply port 112a. The structure of the air flow pushing component 120 is not specifically limited herein. In order to facilitate the air flow pushing component 120 to move toward the side away from the air supply port 112a, a ventilation port can be opened on the bottom wall or the side wall adjacent to the bottom wall of the wind tunnel 111.

[0062] The shapes of the air outlet 111a and the air supply port 112a can be circular, rectangular, elliptical, polygonal, etc. The wind tunnel 111 is generally arranged in a cylindrical shape. In one embodiment, as Figure 1 and Figure 2 shown, the flow collector 112 is a flow collecting cover, and the flow collecting cover is tapered from the air outlet 111a to the air supply port 112a. The cross-sectional shape of the flow collecting cover can be circular, elliptical, rectangular, etc. In order to reduce the wind resistance, the flow collecting cover is generally in a cylindrical shape. By making the flow collecting cover tapered from the air outlet 111a to the air supply port 112a, the flow collecting cover can collect the air sent out from the air outlet 111a and make the generation and blowing of the vortex ring smoother.

[0063] In another embodiment, the current collector 112 is a current collecting plate, which is installed at the air outlet 111a. An air supply port 112a is formed on the current collecting plate. The current collecting plate can be a plate covering the air outlet 111a. By forming an air supply port 112a smaller than the air outlet 111a on the current collecting plate, when the air flow blows from the air outlet 111a to the air supply port 112a, due to the partial blocking effect of the current collecting plate, the air flow blown out from the air supply port 112a can be in a vortex ring shape. Moreover, the structure of the current collecting plate is simple and easy to manufacture and process. In other embodiments, the current collector 112 can also be formed by enclosing several plates. By setting the air supply port 112a on one of the plates, a vortex ring can also be formed. The current collector 112 can also be formed by combining a current collecting plate and a current collecting cover.

[0064] The current collector 112 and the air duct 111 can be integrally formed or separately formed. It can be understood that when the current collector 112 and the air duct 111 are separately formed, the current collector 112 and the air duct 111 are hermetically connected. When the current collecting cover and the air duct 111 are integrally formed, a virtual dividing line is defined with the connection between the air duct 111 and the current collector 112 as the boundary. One side of the dividing line is the air duct 111, and the other side is the current collector 112. An air outlet 111a of the air duct 111 is formed at the dividing line. Undoubtedly, the air passing area of the air outlet 111a is larger than the air passing area of the air supply port 112a of the current collector 112. The extending directions of the outer wall surfaces of the current collector 112 and the air duct 111 can be the same, that is, the length extension lines of their outer wall surfaces are in a straight line. At this time, the vortex ring air supply part is in a complete shape without a connection line. The extending directions of the outer wall surfaces of the current collector 112 and the air duct 111 can be different, that is, the length extension lines of their outer wall surfaces are arranged at an angle. At this time, a connection line will be formed at the connection between the current collector 112 and the air duct 111.

[0065] By making the air passing area of the air supply port 112a smaller than that of the air outlet 111a, in the air flow flowing from the air outlet 111a to the air supply port 112a, part of the air flow will flow along the inner wall surface of the current collector 112 and then flow out from the periphery of the air supply port 112a, and the other part of the air flow will flow out from the middle of the air supply port 112a. The part of the air flow flowing out from the edge of the air supply port 112a is defined as the edge air flow, and the air flow flowing out from the middle of the air supply port 112a is positioned as the middle air flow. Then, due to the resistance of the inner wall surface of the current collector 112, the edge air flow has a lower flow rate compared to the middle air flow. This difference in flow rate will cause a vortex ring air flow when the air flow flows out from the air supply port 112a. At the same air volume, the vortex ring air supply method can achieve directional, fixed-point, and long-distance air supply. Moreover, heat exchange occurs between the vortex ring and the surrounding ambient air during transmission, and the temperature difference between the vortex ring temperature and the surrounding air temperature is not large, ensuring that there is no obvious overcooling or overheating feeling when the vortex ring blows on people and improving comfort.

[0066] It can be understood that the roller assembly 130 includes one or more rollers 131 to achieve rolling. Of course, the roller assembly 130 can also include a plurality of balls to achieve rolling. The roller 131 or the balls can be directly mounted on the air flow pushing assembly 120 or the housing 110, or can be mounted through the roller 131 mounting seat. The roller assembly 130 and the air flow pushing assembly 120 or the housing 110 can be detachably mounted, such as snap connection, screw connection, etc., or can be fixedly connected, such as welding, riveting, etc. When the roller assembly 130 is mounted on the air flow pushing assembly 120, the roller assembly 130 rolls in cooperation with the inner wall surface of the housing 110, and the air flow pushing assembly 120 is rollingly connected to the housing 110 through the roller assembly 130. That is, the air flow pushing assembly 120 can roll along the axial direction of the housing 110 within the housing 110. Thus, on the one hand, since the friction between the air flow pushing assembly 120 and the housing 110 is rolling friction, compared with the sliding friction between the periphery of the air flow pushing assembly 120 and the housing 110, the friction force is greatly reduced, the sliding friction is converted into rolling friction, and the movement noise is reduced, so that the overall movement noise of the vortex ring generating device 100 is small; on the other hand, since the circumferential direction of the air flow pushing assembly 120 contacts the inner wall surface of the housing 110 through the roller assembly 130, the roller assembly 130 can also play a guiding role in the axial movement of the air flow pushing assembly 120. Thus, compared with guiding through a guiding rod, the sliding friction between the guiding rod and the housing 110 is converted into rolling friction, further reducing the noise.

[0067] When the roller assembly 130 is mounted on the housing 110, multiple rows of rollers 131 or balls can be arranged on the housing 110 corresponding to the moving stroke of the air flow pushing assembly 120. Each row of rollers 131 or balls is spaced circumferentially along the housing 110, and the gap between two adjacent rows of balls or rollers is less than or equal to the thickness of the air flow pushing assembly 120, so that when the air flow pushing assembly 120 moves axially along the housing 110, the friction between it and the housing 110 is rolling friction, and the air flow pushing assembly 120 is prevented from getting stuck between two adjacent rows of rollers 131 or balls.

[0068] The structure of the driving device 140 can be of many types. In one embodiment, the driving device 140 includes an electromagnetic driving member 141 and a push rod. One end of the push rod is connected to the air flow pushing assembly 120, and the other end is connected to the electromagnetic driving member 141. By energizing and de-energizing the electromagnetic driving member 141, the push rod is driven to make a reciprocating motion, so as to drive the push plate to make a reciprocating movement between the air supply port 112a and the air exchange port. In another embodiment, the driving device 140 includes a driving motor, a gear and a rack that mesh with each other. One end of the rack is connected to the air flow pushing assembly 120. The gear is driven by the driving motor to drive the rack to move, thereby driving the air flow pushing assembly 120 to make a reciprocating movement. It is also possible to make the motor only drive the air flow pushing assembly 120 to move to the side away from the air supply port 112a, and the air flow pushing assembly 120 is restored to move toward the side close to the air supply port 112a through the elastic reset member 144. In yet another embodiment, the driving device 140 includes a driving motor, a scroll ring and a worm that mesh with each other. One end of the worm is connected to the push plate, and the other end is connected to the turbine. The turbine is fixedly installed on the driving shaft of the driving motor. By driving the turbine to rotate by the driving motor, the worm is driven to make a reciprocating movement, and further drive the push plate to make a reciprocating movement between the air supply port 112a and the air exchange port. In still another embodiment, the driving device 140 includes a driving motor, an eccentric wheel and a connecting rod. The eccentric wheel is arranged on the driving motor. One end of the connecting rod is connected to the rotating shaft of the eccentric wheel, and the other end is connected to the push plate. In this way, the reciprocating movement of the connecting rod driving the push plate can be realized.

[0069] When it is necessary to eject the scroll ring air flow, the driving device 140 drives the push plate to move toward the air exchange port side, discharges the gas in the housing 1101 from the air exchange port, and then the driving device 140 drives the air flow pushing assembly 120 to move quickly toward the air supply port 112a side. The air flow pushing assembly 120 pushes the air flow to quickly blow out from the air supply port 112a. By making the air passing area of the air supply port 112a smaller than the air passing area of the air outlet 111a, a scroll ring air flow can be blown out from the air supply port 112a. By repeating this cycle, a scroll ring air flow can be periodically blown out from the air supply port 112a.

[0070] The vortex ring generating device 100 of the present invention makes the air passing area of the air supply port 112a smaller than that of the air outlet 111a, and the air flow pushing component 120 is movably arranged in the housing 110. The driving device 140 drives the air flow pushing component 120 to reciprocate axially in the housing 110 to periodically push the air flow out from the air supply port 112a. Then, the vortex ring air flow can be periodically output from the air supply port 112a, and directional, fixed-point and long-distance air supply can be realized. At the same time, by installing the roller assembly 130 on one of the air flow pushing component 120 and the housing 110 and rollingly mating with the other of the air flow pushing component 120 and the housing 110, the air flow pushing component 120 can move axially along the housing 110. Then, the air flow pushing component 120 rolls relative to the inside of the housing 110, so that while the air flow pushing component 120 is guided to move axially along the housing 110, the guiding and contact friction forces are reduced, thereby effectively reducing the noise of the vortex ring generating device 100.

[0071] In practical applications, please refer to Figures 2 to 5 , the air flow pushing component 120 includes a push plate, and multiple groups of roller assemblies 130 are circumferentially spaced on the push plate. The air flow pushing component 120 is rollingly connected to the inner wall surface of the housing 110 through the roller assemblies 130. Specifically, the number of the roller assemblies 130 can be two groups, three groups, four groups, five groups, six groups, etc. By arranging multiple groups of roller assemblies 130 circumferentially spaced on the push plate, the contact between the air flow pushing component 120 and the housing 110 is made more stable, and the air flow pushing component 120 is prevented from deviating radially during the axial movement. That is, multiple groups of roller assemblies 130 play a guiding role for the air flow pushing component 120 and make the axial movement of the air flow pushing component 120 smoother and more stable.

[0072] Specifically, the number of the roller assemblies 130 is three groups or more, and multiple groups of roller assemblies 130 are evenly distributed circumferentially on the push plate. By making the number of the roller assemblies 130 at least three groups and making multiple groups of roller assemblies 130 evenly distributed circumferentially on the push plate, the force on the push plate is made more uniform, and the smoothness of the push plate during axial movement is further improved.

[0073] In one embodiment, as Figure 2 、 Figure 8 and Figure 9 shown, a moving platform 111b extending axially is provided on the inner wall surface of the air duct 111, a moving plane is provided on the moving platform 111b, and the roller assembly 130 includes a plurality of rollers 131, and the plurality of rollers 131 are arranged to rollingly abut against the moving plane.

[0074] In this embodiment, the mobile platform 111b can be integrally formed with the hair dryer 111 or separately formed from the hair dryer 111. Then, the mobile platform 111b can be fixed to the inner wall surface of the hair dryer 111 by means such as bonding or screw connection. At this time, the materials of the mobile platform 111b and the hair dryer 111 can be the same or different. It can be understood that the sizes of the multiple rollers 131 of the roller assembly 130 are approximately equal and are located on the same plane, so as to ensure the rolling smoothness of the roller assembly 130 on the moving plane of the mobile platform 111b. By providing the mobile platform 111b extending along the axial direction on the inner wall surface of the hair dryer 111, the multiple rollers 131 of the roller assembly 130 move on the mobile platform 111b. Compared with the rollers 131 directly moving on the curved surface of the hair dryer 111, it can ensure the moving smoothness of the roller assembly 130 relative to the housing 110 and make the movement of the roller assembly 130 smoother. In an embodiment where there are multiple groups of the roller assembly 130, a mobile platform 111b is provided on the inner wall surface of the housing 110 corresponding to each group of the roller assembly 130. Specifically, please refer to Figures 2 to 10 , the number of rollers 131 of each group of the roller assembly 130 can be two, three, four, etc. Then, when the air flow pushing assembly 120 moves, the multiple rollers 131 move in the same direction simultaneously.

[0075] There can be many materials for the mobile platform 111b and the rollers 131. In one embodiment, the mobile platform 111b is made of a hard material, and the outer surface of the roller 131 is made of a hard material. In another embodiment, the mobile platform 111b is made of a hard material, and the outer surface of the roller 131 is made of a soft material. In yet another embodiment, the mobile platform 111b is made of a soft material, and the outer surface of the roller 131 is made of a hard material. In still another embodiment, the mobile platform 111b is made of a soft material, and the outer surface of the roller 131 is made of a soft material. The hard material can specifically be wood, metal, hard plastic, etc. The soft material can be silica gel, rubber, etc. By making at least one of the outer wall surfaces of the mobile platform 111b and the rollers 131 made of a hard material, the wear resistance can be improved, and thus the service life can be extended. And by making at least one of the outer wall surfaces of the mobile platform 111b and the rollers 131 made of a soft material, the noise generated when the roller assembly 130 moves is smaller. In other embodiments, it is also possible to stick or coat a soft or hard material on the outer wall surfaces of the mobile platform 111b and the rollers 131 to meet the usage requirements.

[0076] In one embodiment, as Figures 3 to 5 , Figure 10As shown, the roller assembly 130 can move radially along the air flow pushing assembly 120. The vortex ring generating device 100 further includes an adjusting assembly 150. One end of the adjusting assembly 150 abuts against the air flow pushing assembly 120, and the other end abuts against the roller assembly 130 to adjust the moving distance of the roller assembly 130 so that the roller assembly 130 rolls and abuts against the inner wall surface of the housing 110.

[0077] In this embodiment, the adjusting assembly 150 can specifically be a hydraulic damper, a compression spring or other devices that can adjust the displacement and pressure rotatably. Preferably, a hydraulic damper is used, which has advantages such as sensitive reaction and small frictional resistance. Specifically, the roller assembly 130 is movably installed on the air flow pushing assembly 120 and can move radially along the air flow pushing assembly 120. The adjusting assembly 150 can be installed on the air flow pushing assembly 120 such that the free end of the adjusting assembly 150 abuts against the roller assembly 130, thereby adjusting the height of the roller assembly 130 protruding from the air flow pushing assembly 120, and further adjusting the gap between the roller 131 of the roller assembly 130 and the inner wall surface of the housing 110. It can also be such that the adjusting assembly 150 is installed on the air flow pushing assembly 120, and the roller assembly 130 is directly installed at the free end of the adjusting assembly 150, and then drives the adjustment of the gap between the roller assembly 130 and the inner wall surface of the housing 110. By setting the adjusting assembly 150 to adjust the gap between the roller assembly 130 and the inner wall surface of the housing 110, a certain pre-compression amount can be set to provide pressure to the roller assembly 130, so that the roller assembly 130 always remains in contact with the inner wall surface of the air duct 111, and it can be ensured that when the air flow pushing assembly 120 moves axially, the roller assembly 130 always remains in contact with the inner wall surface of the air duct 111, thereby ensuring the smoothness and fluency of the movement of the air flow pushing assembly 120. And because the adjusting assembly 150 is provided, the assembly accuracy between the roller assembly 130 and the air duct 111 can be reduced, thus facilitating the installation and manufacture of the roller assembly 130.

[0078] Based on the above embodiment, further, as Figures 3 to 5As shown, there are two or more sets of adjusting components 150, and at least two adjusting components 150 are asymmetrically arranged relative to the axial direction of the air flow pushing component 120. The adjusting components 150 can specifically be two sets, three sets, four sets, etc. The two adjusting components 150 are asymmetrically arranged relative to the axial direction of the air flow pushing component 120, that is, the two adjusting components 150 are not axially symmetric about the air flow pushing component 120. When the number of rolling components is three, the number of adjusting components 150 can be two or three. When the number of rolling air flow components is four and they are evenly distributed along the circumferential direction of the air flow pushing component 120, the four roller components 130 are axially symmetric in pairs about the air flow pushing component 120. At this time, an adjusting component 150 is arranged on one of each pair of symmetric roller components 130. Then, while ensuring that the roller components 130 are always in contact with the housing 110, the number of adjusting components 150 is reduced, the cost is lowered, and the overall structure is simplified.

[0079] In one embodiment, please refer to Figure 5 , the air flow pushing component 120 is provided with a first installation groove 121 and a second installation groove 122 that are in communication with each other. The first installation groove 121 is provided at the periphery of the air flow pushing component 120 and is for the roller component 130 to be movably installed. The second installation groove 122 extends from the bottom of the first installation groove 121 towards the middle of the air flow pushing component 120, and the adjusting component 150 is installed in the second installation groove 122.

[0080] In this embodiment, the size of the first installation groove 121 should be larger than the size of the roller component 130, so that the roller component 130 can move radially along the air flow pushing component 120. The second installation groove 122 extends from the bottom of the first installation groove towards the middle of the air flow pushing component 120. When the adjusting component 150 is adaptively installed in the second installation groove, it extends radially along the air flow pushing component 120. In this way, one end of the adjusting component 150 abuts against the bottom wall surface of the second installation groove 122, and the other end abuts against the rolling component. Thus, the protruding height of the roller component 130 can be adjusted radially along the air flow pushing component 120, and further the roller component 130 can always be kept in contact with the inner wall surface of the housing 110.

[0081] Based on the above embodiments, further, the side of the first installation groove 121 has a first opening 121a for installing the roller assembly 130, and the side of the second installation groove 122 has a second opening 123 for installing the adjustment assembly 150; the vortex ring generating device 100 further includes a cover body 160 that detachably covers the first opening 121a and the second opening 123. By providing the first opening 121a on the side of the first installation groove 121 and the second opening 123 on the side of the second installation groove 122, the roller assembly 130 and the adjustment assembly 150 can be installed into the first installation groove 121 and the second installation groove 122 from the first opening 121a and the second opening 123 on the side. Thus, it is convenient for the installation of the roller assembly 130 and the adjustment assembly 150. The cover body 160 and the air flow pushing assembly 120 can be detachably connected by means such as screws and snap connections. The shape and size of the cover body 160 should be adapted to the overall shape of the first opening 121a and the second opening 123. By providing the cover body 160 to cover the first opening 121a and the second opening 123, the roller assembly 130 and the adjustment assembly 150 can be prevented from falling, thereby improving the installation stability of the roller assembly 130 and the adjustment assembly 150, and maintaining the overall consistency and integrity of the air flow pushing assembly 120.

[0082] In one embodiment, as Figures 3 to 10 shown, the roller assembly 130 further includes an installation box 132 and at least three rollers 131 installed in the installation box 132. The installation box 132 is installed in the first installation groove 121 so as to be movable radially along the air flow pushing assembly 120. One end of the adjustment assembly 150 abuts against the bottom wall surface of the second installation groove 122, and the other end abuts against the installation box 132.

[0083] In this embodiment, the overall shape of the mounting box 132 can be rectangular, disc-shaped, etc., as long as it can accommodate the installation of the rollers 131. The mounting box 132 can be an integral structure or formed by detachably connecting two half-shells. It can be understood that in order to make the contact between the adjusting component 150 and the mounting box 132 more stable, the surface of the mounting box 132 in contact with the adjusting component 150 is a flat surface. One end of the adjusting component 150 can directly abut against the mounting box 132, or a positioning sleeve can be provided on the mounting box 132 to sleeve one end of the adjusting component 150, or one end of the adjusting component 150 can be fixed on the mounting box 132. As long as the adjusting component 150 can adjust the moving distance of the mounting box 132 in the radial direction of the air flow pushing component 120. The rollers 131 are installed in the mounting box 132, and the mounting box 132 is provided with an extending outlet for part or all of the rollers 131 to extend out. By providing the mounting box 132, multiple rollers 131 are centrally installed in the mounting box 132. Compared with the individual setting of multiple rollers 131, it is integrated and modular, which is convenient for the installation and disassembly of multiple rollers 131. In addition, by only abutting the adjusting component 150 against the mounting box 132, the displacement amounts of multiple rollers 131 in the radial direction can be adjusted simultaneously, and it is easy to control the simultaneous movement or stop of multiple rollers 131 in the same direction.

[0084] Specifically, the number of the rollers 131 can be three, four, five, six, etc. In one embodiment, as Figure 7 shown, the roller assembly 130 includes a first shaft 133 and a second shaft 134 arranged in parallel in the mounting box 132. One roller 131 is provided at each end of the first shaft 133; one roller 131 is provided on the second shaft 134, and the roller 131 on the second shaft 134 is correspondingly arranged in the middle of the two rollers 131 on the first shaft 133. Then the first shaft 133 can be set as the long shaft, and the second shaft 134 can be set as the short shaft. In this way, when there is only one set of the first shaft 133 and the second shaft 134, the three rollers 131 are arranged in an isosceles triangle, making the rolling of the entire mounting box 132 more stable. When the number of the rollers 131 is five, the second shaft 134 can be located between two first shafts 133, and the five rollers 131 are arranged in a plum blossom shape. The number and arrangement of the first shaft 133 and the second shaft 134 can be selected and designed according to actual needs, and will not be listed one by one here.

[0085] In another embodiment, the roller assembly 130 includes a first shaft 133 and a second shaft 134 arranged in parallel in the mounting box 132. One roller 131 is provided at each end of the first shaft 133; one roller 131 is provided at each end of the second shaft 134, and the two rollers 131 on the second shaft 134 are arranged corresponding to the two rollers 131 on the first shaft 133. That is, multiple rows of rollers 131 are arranged in parallel. In this way, the movement stability of the entire roller assembly 130 can also be ensured. The number of the first shaft 133 and the second shaft 134 can be selected and designed according to actual needs, and will not be listed one by one here.

[0086] In combination with the above embodiment having the mounting box 132, further, please refer to Figures 5 to 7 , one of the first mounting groove 121 and the mounting box 132 is provided with a guide groove 132a extending along the radial direction of the air flow pushing component 120, and the other is provided with a guide rod 122a adapted to be installed in the guide groove 132a.

[0087] In this embodiment, define the protruding surface of the roller 131 in the mounting box 132 and its opposite surface as the end surface, and the surface around the two end surfaces in the circumferential direction as the circumferential side surface. Then, a guide groove 132a / guide rod 122a is provided on the circumferential side surface of the mounting box 132, and a guide rod 122a / guide groove 132a is provided at the position of the first mounting groove 121 corresponding to the guide groove 132a / guide rod 122a. The number of the guide rod 122a and the guide groove 132a can be one, two or more. In order to make the guiding of the guide rod 122a more stable, the guide rod 122a or the guide groove 132a should be provided on the opposite two circumferential side surfaces of the mounting box 132. On the basis of the embodiment having a cover body, the guide rod 122a or the guide groove 132a can be provided on the inner wall surface of the cover body facing the first mounting groove 121 and the bottom wall surface of the first mounting groove 121. The mounting box 132 is installed in the first mounting groove 121 through the guide rod 122a and the guide groove 132a, so that it can be ensured that the mounting box 132 can move radially in the first mounting groove 121 along the air flow pushing component 120 while limiting the movement of the mounting box 132 in the direction perpendicular to the radial direction of the air flow pushing component 120 in the first mounting groove 121. Thus, the shaking of the mounting box 132 in the direction other than the radial direction of the air flow pushing component 120 is avoided, and the adjustment component 150 can adjust the radial movement of the entire roller assembly 130 more precisely.

[0088] In one embodiment, please refer to Figures 2 to 4, the driving device 140 includes a driving member 141, a wire wheel 142, a flexible belt 143 and a reset member 144. One end of the flexible belt 143 is fixed to the air flow pushing assembly 120, and the other end is fixed to the wire wheel 142. The driving member 141 is connected to the wire wheel 142 to drive the flexible belt 143 to drive the air flow pushing assembly 120 to move towards the side away from the air outlet 112a; one end of the reset member 144 is connected to the air flow pushing assembly 120, and the other end is connected to the housing 110 to drive the air flow pushing assembly 120 to reset and move towards the side close to the air outlet 112a.

[0089] In this embodiment, it can be understood that the length of the flexible belt 143 should be greater than the moving stroke of the air flow pushing assembly 120, so that when the air flow pushing assembly 120 is closest to the air outlet 112a, the flexible belt 143 can pull the air flow pushing assembly 120 to gradually move away from the air outlet 112a. The flexible belt 143 refers to a belt-like structure that can be easily deformed but not easily damaged. The material of the flexible belt 143 can be fabric materials such as nylon, cotton, and fiber, plastic materials such as polyvinyl chloride, polyethylene, polypropylene, and polyester, rubber materials, etc., or can be formed by splicing or mixing the above materials. In order to further improve the transmission effect, the flexible belt 143 can also be a synchronous belt. This makes the transmission more accurate and stable, and has the ability of buffering and vibration reduction, thereby further reducing noise. One end of the flexible belt 143 can be fixed to the air flow pushing assembly 120 by means of welding, clamping, screw connection, bonding, etc. The reset member 144 can specifically be a compression spring, a magnetic member, or other structures that can drive the air flow pushing assembly 120 to reset and move.

[0090] The driving member 141 can be a driving cylinder, a driving motor, etc. The driving motor has advantages such as small volume and easy control. Hereinafter, the driving motor will be taken as an example for exemplary illustration. One end of the flexible belt 143 is fixed on the wire wheel 142, so that the flexible belt 143 can be wound around the winding surface of the wire wheel 142. The driving shaft of the driving motor is fixedly connected to the wire wheel 142, and then drives the wire wheel 142 to rotate forward to wind the flexible belt 143 when the driving motor is powered on. When the driving motor is powered off, the wire wheel 142 can rotate reversely under a small driving force, so that the flexible belt 143 can be stretched from the wire wheel 142 when the air flow push plate assembly moves back to its original position. By providing the wire wheel 142 and winding the flexible belt 143 on the wire wheel 142, the winding of the flexible belt 143 is more regular and not prone to deviation, thus facilitating the contraction and extension of the flexible belt 143. When the driving member 141 works, the driving force is greater than the restoring force of the restoring member 144, so that the flexible belt 143 can be wound by the wire wheel 142 to pull the air flow pushing assembly 120 to move toward the side away from the air outlet 112a. When the driving member 141 stops working, the driving force disappears, and the restoring force of the restoring member 144 drives the air flow pushing assembly 120 to quickly move back toward the side close to the air outlet 112a, and at the same time drives the flexible belt 143 to stretch. In this way, the air flow pushing assembly 120 can be reciprocated periodically along the axial direction of the housing 110.

[0091] The driving member 141 drives the wire wheel 142 to wind the flexible belt 143 to drive the air flow pushing assembly 120 to move toward the side away from the air outlet 112a, and the restoring member 144 drives the air flow pushing assembly 120 to move toward the side close to the air outlet 112a. Compared with the gear-rack transmission method, converting the rigid transmission into a flexible transmission can effectively reduce the vibration noise and movement friction noise of the vortex ring generating device 100, thereby greatly improving the user experience.

[0092] The present invention also provides an indoor air conditioner. Please refer Figure 11 to Figure 12 , this indoor air conditioner includes a housing 200 and a vortex ring generating device 100. The vortex ring generating device 100 is installed in the housing 200. The specific structure of the vortex ring generating device 100 refers to the above-mentioned embodiment. Since this indoor air conditioner adopts all the technical solutions of the above-mentioned all embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, and will not be elaborated here one by one. The vortex ring generating device 100 can be specifically installed on the housing 200 or installed inside the housing 200. And the air duct of the vortex ring generating device 100 can be communicated with the heat exchange air duct 210 inside the housing 200 or not. This indoor air conditioner can be an indoor air conditioner, a mobile air conditioner, a wall-mounted indoor air conditioner, a window air conditioner, etc.

[0093] In one embodiment, please refer againFigure 11 and Figure 12 Inside the housing 200, there are a heat exchange air duct 210 and an installation opening 220. The vortex ring generating device 100 is installed inside the housing 200, and the air supply opening 112a of the vortex ring generating device 100 communicates with the room through the installation opening 220;

[0094] The indoor unit of the air conditioner further includes a guiding member 300 connected to the air supply opening 112a. The guiding member 300 is arranged around the air supply opening 112a. A diffusing air outlet channel 230 is formed between the outer wall surface of the guiding member 300 and the inner wall surface of the installation opening 220. The diffusing air outlet channel 230 communicates with the heat exchange air duct 210. The guiding member 300 is used to guide the air flow at the diffusing air outlet channel 230, so that the air flow blown out from the diffusing air outlet channel 230 deviates from the air flow direction blown out from the air supply opening 112a.

[0095] In this embodiment, the housing 200 can be integrally formed or separately formed, such as being spliced by two sub - housings. The shape of the installation opening 220 of the housing 200 can be circular, oval, rectangular, polygonal, irregular, etc., and its shape is not specifically limited herein. The shape of the installation opening 220 and the air supply opening 112a can be the same or different. Since the air supply opening 112a communicates with the room through the installation opening 220, the flow - collecting member 112 can be arranged inside the housing 110 so that the air supply opening 112a is arranged corresponding to the vortex ring air outlet 111a; or the flow - collecting member 112 can be abutted against the panel, that is, the vortex ring air outlet 111a is connected to the air supply opening 112a; or the flow - collecting member 112 can extend out of the panel so that the air supply opening 112a is located outside the panel.

[0096] The guiding member 300 is arranged around the air supply opening 112a, so the guiding member 300 can be connected to the outer peripheral side wall of the flow - collecting member 112. Through the action of the guiding member 300, the air flow on the outer peripheral side wall of the flow - collecting member 112 can be smoothly guided to deviate from the direction of the vortex ring air flow being blown out, thereby preventing the air flow blown out from the diffusing air outlet channel 230 from affecting the formation and air supply of the vortex ring air flow. The guiding member 300 can be arranged inside the housing 200, or extend out of the housing 200, or be flush with the housing 200. When the guiding member 300 is arranged inside the housing 200 or is flush with the housing 200, the radial dimension of the air outlet 111a of the guiding member 300 should be smaller than the radial dimension of the installation opening 220, so as to smoothly form the diffusing air outlet channel 230 between the outer wall surface of the guiding member 300 and the inner wall surface of the installation opening 220.

[0097] The flow guide member 300 and the current collector 112 of the vortex ring generating device 100 can be integrally formed or separately formed. It should be noted that when the flow guide member 300 and the current collector 112 are integrally formed and the flow guide member 300 extends out of the housing 200, the radial dimension of the position of the flow 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 111a is formed in the middle of the mounting port 220, and a diffused air outlet channel 230 is formed around it. When the flow guide member 300 and the current collector 112 are separately formed, the flow guide member 300 extends out of the housing 200, and the current collector 112 of the vortex ring generating device 100 is arranged in the housing 110. The air supply port 112a is located inside the panel. At this time, the radial dimension of the position of the flow guide member 300 corresponding to the mounting port 220 should be smaller than the radial dimension of the mounting port 220, so that a diffused air outlet channel 230 is formed by enclosing between the flow guide member 300 and the inner wall surface of the mounting port 220. The air flow blown out from the diffused air outlet channel 230 can achieve draft-free air supply, the air supply is softer, and the comfort is higher.

[0098] In one embodiment, the flow guide member 300 is a flow guide cylinder, and a flow guide plate is provided at one end of the flow guide cylinder away from the air supply port 112a. When the flow guide member 300 is arranged in the housing 200, the whole flow guide cylinder can be in a form that gradually expands from the inside to the outside, or the flow guide plate can be in a form that gradually expands from the inside to the outside. When the flow guide member 300 extends out of the housing 200, the flow guide cylinder can be a straight cylinder, and the flow guide plate can also be in a straight plate form. In this way, the flow guide cylinder is connected to the current collector 112. On the one hand, it guides the blowing of the vortex ring air flow, and on the other hand, it guides the air flow blown out from the diffused air outlet channel 230 to the direction of the blowing of the vortex ring air flow away from the air supply port 112a, so that the air flow blown out from the diffused air outlet channel 230 does not affect the vortex ring air flow. At this time, the flow guide cylinder and the current collector 112 can be arranged in an integral form without a connecting wire, and the flow guide cylinder can also be in a straight cylinder shape.

[0099] The heat exchange air duct 210 means that the air flow entering from the main air inlet can exchange heat in this duct and then be blown out from the main air outlet. A heat exchanger is provided in the heat exchange air duct 210, and a water receiving tray is arranged below the heat exchanger for collecting and discharging condensed water. The heat exchange air duct 210 can be directly formed by enclosing the housing 200, or can be formed by enclosing the inner wall of the air duct in the housing 200. The cross-sectional shapes of the housing 200 and the heat exchange air duct 210 can be circular, oval, rectangular, polygonal, etc. The extending shape of the heat exchange air duct 210 can be a straight cylinder type or a bent type, etc.

[0100] In the air conditioner indoor unit of the present invention, a flow guide member 300 is provided at the air outlet 112a of the vortex ring generating device 100, so that a diffused air outlet passage 230 is formed between the outer wall surface of the flow guide member 300 and the inner wall surface of the mounting opening 220. The flow guide member 300 is used to guide the air flow blown out from the diffused air outlet passage 230, so that the air flow blown out from the diffused air outlet passage 230 deviates from the direction of the vortex ring air flow. In this way, the mounting opening 220 formed on the panel is fully utilized, so that the vortex ring air flow is blown out from the middle of the mounting opening 220, and the heat exchange diffused air flow is blown out around. Moreover, the air flow blown out from the diffused air outlet passage 230 does not affect the vortex ring air flow. In this way, while the vortex ring accurately supplies air with a long air supply distance and high propagation efficiency, combined with diffused air outlet, the air supply area of the entire air conditioner indoor unit is wider, the air supply distance is farther, and the heat exchange efficiency is high, so that the space temperature is more uniform and the comfort level is higher.

[0101] In one embodiment, please refer to Figure 12 , the housing 200 includes a panel and two side plates connected to both sides of the panel. The mounting opening 220 is provided on the panel, and at least one side plate is provided with a main air outlet, and the main air outlet is communicated with the heat exchange air duct 210.

[0102] It can be understood that the two opposite side plates connected to both sides of the panel refer to the side plates located on the left and right sides of the entire housing 200. A main air outlet can be provided on one of the side plates, or main air outlets can be provided on both side plates. In order to make the air outlet range wider and the air outlet area larger, preferably, main air outlets are provided on both side plates. The shape of the main air outlet can be circular, oval, strip-shaped, etc. In order to make the air output larger, preferably, it is strip-shaped. The panel and the two side plates can be integrally formed or separately formed. An air inlet is also provided on the housing 200, and the air conditioner indoor unit further includes a heat exchange fan, and the heat exchange fan is installed in the heat exchange air duct 210. The heat exchange fan is used to drive sufficient air flow to flow through the heat exchange air duct 210 from the air inlet and be blown out from the main air outlet. The air inlet can be provided on the panel and / or the two side plates, and can also be provided on the rear panel of the housing 200. By providing the main air outlet on the side plate, the air flow of the conventional air supply does not affect the vortex ring air flow. While making the air outlet area wide, the air supply distance far, and the air supply forms diverse, the propagation efficiency of the air flow is high, so that the heat exchange efficiency of the room is improved, the temperature of the space is more uniform, and the comfort level is further improved. The conventional air supply and the vortex ring air supply can be turned on simultaneously or separately.

[0103] The present invention further provides an air conditioner, which includes an indoor unit and an outdoor unit of the air conditioner connected by a refrigerant pipe. Among them, the indoor unit of the air conditioner includes a vortex ring generating device 100. The specific structure of the vortex ring generating device 100 refers to the above embodiments. Since the indoor unit of the air conditioner adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one.

[0104] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
