Description

Technical Field

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

[0002] In existing air conditioners, 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 shell. However, when the air flow pushing component is quickly pushed out, it needs to stop after reaching a specific position. Conventional ways to stop and limit the air flow pushing component include setting deformable materials such as rubber and springs to contact and deform with the air flow pushing component to stop the movement, or directly colliding the air flow pushing component with a hard plastic to stop. These methods all have the defect of generating collision noise when the air flow pushing component contacts other media instantaneously, thus affecting the user experience.

[0004] The above content is only used to assist in understanding the technical solution of the invention, and does not represent an admission that the above content is prior art. Summary of the Invention

The air passing area of the air supply port is smaller than the air passing area of the air outlet. A thrust portion is convexly provided on the inner wall surface of the housing near the air supply port. In the direction toward the air supply port, the height of the thrust portion protruding from the inner wall surface gradually increases;

[0023] The air flow pushing assembly is movably arranged in the housing, and when the air flow pushing assembly moves toward the air supply port, it can stop under the action of the thrust portion;

[0024] The roller assembly is installed on one of the peripheral edge of the air flow pushing assembly and the inner wall surface of the housing, and is in rolling cooperation with the other of the peripheral edge of the air flow pushing assembly and the inner wall surface of the housing, so that the air flow pushing assembly can move along the axial direction of the housing;

[0025] The driving device is used to drive the air flow pushing assembly to reciprocate in the housing to periodically push the air flow out of the air supply port.

[0027] The indoor air conditioner further includes a guiding member connected to the air supply port. The guiding member surrounds the air supply port, and a diffused air outlet channel is formed between the outer wall surface of the guiding member and the inner wall surface of the installation opening. The diffused air outlet channel communicates with the heat exchange air duct. The guiding member is used to guide the air flow at the diffused air outlet channel so that the air flow blown out from the diffused air outlet channel deviates from the air flow direction blown out from the air supply port.

[0028] The present invention also provides an air conditioner, which includes an outdoor unit and an indoor unit of the air conditioner connected by a refrigerant pipe. The indoor unit of the air conditioner includes a housing and a vortex ring generating device installed in the housing. Among them, the vortex ring generating device includes a housing, an air flow pushing component, a roller component and a driving device;

[0029] The housing includes a wind tube and a flow collector. One end of the wind tube is provided with an air outlet, the flow collector is installed at the air outlet, and an air supply port communicating with the wind tube is arranged on the flow collector. The air passing area of the air supply port is smaller than that of the air outlet. A thrust portion is convexly provided on the inner wall surface of the housing on the side close to the air supply port. In the direction towards the air supply port, the height of the thrust portion protruding from the inner wall surface gradually increases;

[0030] The air flow pushing component is movably arranged in the housing, and when the air flow pushing component moves towards the side close to the air supply port, it can stop under the action of the thrust portion;

[0031] The roller component is installed on one of the peripheral edge of the air flow pushing component and the inner wall surface of the housing, and is in rolling cooperation with the other of the peripheral edge of the air flow pushing component and the inner wall surface of the housing, so that the air flow pushing component can move along the axial direction of the housing;

[0032] The driving device is used to drive the air flow pushing component to reciprocate in the housing, so as to periodically push the air flow out of the air supply port.

[0033] By making the air passing area of the air supply port smaller than that of the air outlet, and the air flow pushing component is movably arranged in the housing, and the driving device drives the air flow pushing component to reciprocate in the housing to periodically push the air flow out of the air supply port, the vortex ring generating device of the present invention can periodically output vortex ring air flow from the air supply port, and can realize directional, fixed-point and long-distance air supply. At the same time, by installing the roller component on one of the peripheral edge of the air flow pushing component and the inner wall surface of the housing, and being in rolling cooperation with the other of the peripheral edge of the air flow pushing component and the inner wall surface of the housing, the air flow pushing component can move along the axial direction of the housing. Then the air flow pushing component rolls relatively in the housing, so as to reduce the guiding and contact friction while making the air flow pushing component move in a guiding manner along the axial direction of the housing, and further effectively reduce the movement noise of the vortex ring generating device.

[0034] In addition, a thrust portion is convexly provided on one side of the inner wall surface of the housing close to the air supply port. In the direction towards the air supply port, the height of the thrust portion protruding from the inner wall surface of the housing gradually increases. When the air flow pushing component rolls from the side far from the air supply port to the thrust portion on the side close to the air supply port, it is gradually subjected to a squeezing force during the forward movement, thereby achieving the effect of rolling braking and deceleration, and further realizing the stop of the air flow pushing component. Compared with the direct frontal collision of the air flow pushing component with other media, this stop limiting method can effectively reduce noise and improve the user's comfort.

Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution where A and B are satisfied simultaneously.

[0054] The present invention provides a vortex ring generating device.

[0055] In the embodiments of the present invention, as Figures 1 to 6As shown, 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. An air outlet 111a is provided at one end of the wind tunnel 111. The flow collector 112 is installed at the air outlet 111a. An air supply opening 112a communicating with the wind tunnel 111 is provided on the flow collector 112. The air passing area of the air supply opening 112a is smaller than that of the air outlet 111a. A thrust portion 113 is protruded on the inner wall surface of the housing 110 on the side close to the air supply opening 112a. In the direction approaching the air supply opening 112a, the height of the thrust portion 113 protruding from the inner wall surface of the housing 110 gradually increases. The air flow pushing component 120 is movably arranged in the housing 110, and when the air flow pushing component 120 moves on the side close to the air supply opening 112a, it can stop under the action of the thrust portion 113. The roller component 130 is installed on one of the peripheral edge of the air flow pushing component 120 and the inner wall surface of the housing 110, and is in rolling cooperation with the other of the peripheral edge of the air flow pushing component 120 and the inner wall surface of 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, so as to periodically push the air flow to blow out from the air supply opening 112a.

[0056] 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 or a bent cylinder shape, and its cross section can be a rectangle, a circle, an ellipse, a polygon, a special shape, etc., which is 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 is 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 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 or a push plate, or can be composed of a push plate and a film provided on the peripheral edge of the push plate, as long as it can push the air flow in the housing 110 so that a vortex ring can be blown out from the air supply opening 112a. The structure of the air flow pushing component 120 is not specifically limited herein. In order to facilitate the movement of the air flow pushing component 120 toward the side away from the air supply opening 112a, a ventilation opening can be provided on the bottom wall of the wind tunnel 111 or the side wall adjacent to the bottom wall.

[0057] The thrust portion 113 can be specifically provided on the flow collector 112, or can be provided at one end of the air duct 111 close to the air outlet 112a. The specific setting position of the thrust portion 113 can be determined according to the moving stroke of the air flow pushing component 120, and no specific limitation is made here. The thrust portion 113 can be integrally provided with the housing 110 or can be separately provided, and is installed on the inner wall surface of the housing 110 by means such as glue bonding and screw connection. The height of the thrust portion 113 protruding from the inner wall surface of the housing 110 is gradually increased from the side far away from the air outlet 112a to the side close to the air outlet 112a. That is, the inner diameter of the housing 110 is gradually decreased from the side far away from the air outlet 112a to the side close to the air outlet 112a at the position corresponding to the thrust portion 113. When the air flow pushing component 120 stops under the action of the thrust portion 113, when the air flow pushing component 120 moves onto the thrust portion 113 and gradually rolls and moves toward the side close to the air outlet 112a, it is subjected to a squeezing force perpendicular to the surface of the thrust portion 113, so that the air flow pushing component 120 is subjected to a force opposite to its moving direction, and thus can gradually prevent the movement of the air flow pushing component 120. Compared with direct contact deceleration, this deceleration method can effectively reduce noise due to rolling friction and slow deceleration.

[0058] It can be understood that the roller assembly 130 can include one or more rollers to achieve rolling. Of course, the roller assembly 130 can also include a plurality of balls to achieve rolling. The rollers or balls can be directly installed on the periphery of the air flow pushing component 120 or the inner wall surface of the housing 110, or can be installed through a roller mounting seat. The roller assembly 130 and the air flow pushing component 120 or the housing 110 can be detachably installed, such as by snap connection and screw connection, or can be fixedly connected, such as by welding and riveting.

[0059] When the roller assembly 130 is installed on the periphery of the air flow pushing assembly 120, the roller assembly 130 is in rolling fit 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 frictional 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. When the air flow pushing assembly 120 rolls to the thrust portion 113 of the housing 110 and continues to move toward the air supply port 112a, the roller assembly 130 is subjected to a squeezing force and a resistance force, thereby stopping the movement of the air flow pushing assembly 120.

[0060] When the roller assembly 130 is installed on the housing 110, multiple rows of rollers or balls can be arranged on the housing 110 corresponding to the movement stroke of the air flow pushing assembly 120. Each row of rollers or balls is spaced circumferentially along the housing 110, and the gap between adjacent two rows of balls or rollers is less than or equal to the thickness of the air flow pushing assembly 120. Thus, 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 adjacent two rows of rollers or balls. It can be understood that the outer wall surface of the thrust portion 113 is also provided with rollers or balls. Thus, when the air flow pushing assembly 120 rolls to the thrust portion 113, it is subjected to a resistance force and then stops on the thrust portion 113.

[0061] The shapes of the air outlet 111a and the air supply port 112a can be circular, rectangular, oval, polygonal, etc. The air duct 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, oval, 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.

[0062] 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 single plate covering the air outlet 111a. By forming an air supply port 112a on the current collecting plate that is smaller than the air outlet 111a, 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.

[0063] 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 demarcation line is defined with the connection between the air duct 111 and the current collector 112 as the boundary. One side of the demarcation 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 demarcation 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 wiring connection. 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 wiring connection will be formed at the connection between the current collector 112 and the air duct 111.

[0064] 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, the vortex ring exchanges heat with 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.

[0065] 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 reciprocate, so as to drive the push plate to reciprocate 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. By driving the gear with the driving motor to drive the rack to move, the air flow pushing assembly 120 is driven to reciprocate. It is also possible to make the motor only drive the air flow pushing assembly 120 to move away from the air supply port 112a, and the elastic reset member 144 is used to realize the reset movement of the air flow pushing assembly 120 toward the side close to the air supply port 112a. 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 scroll ring. The scroll ring is fixedly installed on the driving shaft of the driving motor. By driving the scroll ring to rotate with the driving motor, the worm is driven to reciprocate, and further the push plate is driven to reciprocate 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.

[0066] In the scroll ring generating device 100 of the present invention, by making the air passing area of the air supply port 112a smaller than the air passing area of the air outlet 111a, and the air flow pushing assembly 120 is movably arranged in the housing 110, the driving device 140 drives the air flow pushing assembly 120 to reciprocate in the housing 110, so as to periodically push the air flow out from the air supply port 112a. Then, the scroll 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 making the roller assembly 130 installed on one of the peripheral edge of the air flow pushing assembly 120 and the inner wall surface of the housing 110 and rollingly cooperating with the other of the peripheral edge of the air flow pushing assembly 120 and the inner wall surface of the housing 110, the air flow pushing assembly 120 can move along the axial direction of the housing 110. Then, the air flow pushing assembly 120 rolls relative to the inside of the housing 110, so that while the air flow pushing assembly 120 is guided to move along the axial direction of the housing 110, the guiding and contact friction are reduced, and further the movement noise of the scroll ring generating device 100 is effectively reduced.

[0067] In addition, a thrust portion 113 is convexly provided on one side of the inner wall surface of the housing 110 close to the air outlet 112a. In the direction towards the air outlet 112a, the height of the thrust portion 113 protruding from the inner wall surface of the housing 110 gradually increases. When the air flow pushing assembly 120 is thrusted against the thrust portion 113, when the air flow pushing assembly 120 rolls from the side far away from the air outlet 112a to the thrust portion 113 on the side close to the air outlet 112a, it is gradually subjected to a squeezing force during the forward movement, thereby achieving the effect of rolling braking and deceleration, and further realizing the stop of the air flow pushing assembly 120. Compared with the direct frontal collision of the air flow pushing assembly 120 with other media, this stop limiting method can effectively reduce noise and improve the user's comfort.

[0068] In practical applications, please refer to Figures 2 to 4 , the air flow pushing assembly 120 includes a push plate, and a plurality of roller assemblies 130 are circumferentially spaced on the push plate. The air flow pushing assembly 120 is in rolling connection with the inner wall surface of the housing 110 through the roller assemblies 130, and a thrust portion 113 is provided on the inner wall surface of the housing 110 corresponding to the moving path of each group of roller assemblies 130.

[0069] Specifically, the number of the roller assemblies 130 can be two groups, three groups, four groups, five groups, six groups, etc. By arranging a plurality of roller assemblies 130 at intervals along the circumference of the push plate, the contact between the air flow pushing assembly 120 and the housing 110 is made more stable, and the air flow pushing assembly 120 is prevented from deviating in the radial direction during the axial movement. That is, the plurality of roller assemblies 130 play a guiding role for the air flow pushing assembly 120, and make the axial movement of the air flow pushing assembly 120 more stable and smooth. In addition, compared with arranging the roller assemblies 130 on the inner wall surface of the housing 110, arranging the roller assemblies 130 on the periphery of the push plate can reduce the number of the roller assemblies 130 provided, and further reduce the weight of the entire vortex ring generating device 100. By providing a thrust portion 113 on the inner wall surface of the housing 110 corresponding to the moving path of each group of roller assemblies 130, each group of roller assemblies 130 stops at the corresponding thrust portion 113, so that the overall stop effect of the air flow pushing assembly 120 is better.

[0070] Specifically, the number of the roller assemblies 130 is three groups or more, and the plurality of roller assemblies 130 are evenly distributed along the circumference of the push plate. By making the number of the roller assemblies 130 at least three groups and making the plurality of roller assemblies 130 evenly distributed along the circumference of 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.

[0071] In one embodiment, please refer to Figure 2 、 Figures 4 to 6, the outer surface of the thrust portion 113 is an inclined surface. In this way, while satisfying the stop of the air flow to push the component 120, the structure of the thrust portion 113 is made simpler and easier to process and manufacture. In another embodiment, the outer surface of the thrust portion 113 is a convex arc surface. In yet another embodiment, the outer surface of the thrust portion 113 is a concave arc surface. Making the outer wall surface of the thrust portion 113 an arc surface, since its slope is variably set, the resistance received by the air flow pushing component 120 on the thrust portion 113 gradually changes, so that the resistance and push on the air flow pushing component 120 are smoother, further reducing the movement stop noise of the air flow pushing component 120. In still another embodiment, the outer surface of the thrust portion 113 is composed of two or three combinations of an inclined surface, a convex arc surface, and a concave arc surface. The inclined surface, the convex arc surface, and the concave arc surface can be arbitrarily combined, and the transition between surfaces should be a smooth transition.

[0072] In a preferred embodiment, as Figure 5 and Figure 6 shown, a plane passing through the axis of the housing 110 and perpendicular to the thrust portion 113 is defined as the projection plane, and the included angle (such as the angle a in Figure 5 ) between the connection line between the two end points of the outer surface of the thrust portion 113 on the projection plane and the axis of the housing 110 is greater than 0 degree and less than or equal to 10 degrees. For ease of understanding, the outer surface of the thrust portion 113 is taken as an inclined surface for illustration here. Specifically, the included angle a can be 2 degrees, 5 degrees, 8 degrees, 10 degrees, etc. When the included angle a is greater than 10 degrees, the slope of the thrust portion 113 is too large, so that when the air flow pushing component 120 moves from the inner wall surface of the housing 110 to the thrust portion 113, it will quickly receive a large resistance, which will also cause a relatively large collision noise to a certain extent. And because the slope of the thrust portion 113 is large, after the air flow pushing component 120 stops on the thrust portion 113, a large backward thrust is generated by its gravity, so that the air flow pushing component 120 will fall back to the side away from the air outlet 112a. By making the included angle a less than or equal to 10 degrees, the air flow pushing component 120 is slowly and fully decelerated on the thrust portion 113, thereby reducing the movement stop noise of the air flow pushing component 120 and being able to prevent the air flow pushing component 120 from moving back due to gravity.

[0073] In one embodiment, the height by which the end point of the thrust portion 113 near the air outlet 112a protrudes from the inner wall surface of the housing 110 is greater than 0 and less than or equal to 100 mm. Specifically, the height by which the end point of the thrust portion 113 near the air outlet 112a protrudes from the inner wall surface of the housing 110 can be 5 mm, 10 mm, 20 mm, 35 mm, 50 mm, 75 mm, 90 mm, 100 mm, etc. It can be understood that since the protruding height of the thrust portion 113 gradually increases from the side far from the air outlet 112a to the side close to the air outlet 112a, the end point of the thrust portion 113 near the air outlet 112a, that is, the highest protruding point of the thrust portion 113. When the end point of the thrust portion 113 near the air outlet 112a is greater than mm, on the premise of meeting the angle requirement of the thrust portion 113, the extension length of the thrust portion 113 will be too long, resulting in a larger volume of the housing 110 and a large occupied space. By making the end point of the thrust portion 113 near the air outlet 112a less than or equal to mm, while making the extension length of the thrust portion 113 appropriate, the slope requirement of the thrust portion 113 can be met, thereby rationalizing the length of the housing 110.

[0074] In one embodiment, please refer to again Figure 2 , Figures 4 to 6 , on the inner wall surface of the housing 110 far from the air outlet 112a, a moving platform 114 extending along its axial direction is provided, and the moving platform 114 is smoothly connected to the thrust portion 113. The moving platform 114b can be integrally formed with the air duct 111 or formed separately from the air duct 111. Then, the moving platform 114b can be fixed to the inner wall surface of the air duct 111 by means of bonding, screw connection, etc. At this time, the materials of the moving platform 114b and the air duct 111 can be the same or different. It can be understood that the sizes of the multiple rollers 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 moving platform 114b. By providing a moving platform 114b extending along the axial direction on the inner wall surface of the air duct 111, the multiple rollers of the roller assembly 130 move on the moving platform 114b. Compared with the rollers directly moving on the curved surface of the air duct 111, the moving smoothness of the roller assembly 130 relative to the housing 110 can be ensured, and the movement of the roller assembly 130 is made smoother. In an embodiment where there are multiple groups of the roller assembly 130, a moving platform 114b is provided on the inner wall surface of the housing 110 corresponding to each group of the roller assembly 130. The moving platform 114 is smoothly connected to the thrust portion 113, so that the rolling assembly can smoothly transition from the moving platform 114 to the thrust portion 113, further reducing resistance and noise.

[0075] In one embodiment, as Figure 2 , Figure 4 , Figures 7 to 10, the air flow pushing component 120 is reciprocally movably arranged in the housing 110, and has a first position close to the air outlet 112a and a second position far from the air outlet 112a. The vortex ring generating device 100 further includes a first magnetic member 150 and a second magnetic member 160. The first magnetic member 150 is installed on the air flow pushing component 120, and the second magnetic member 160 is installed on the housing 110 between the air outlet 112a and the first position, so as to generate a repulsive force towards the second position on the first magnetic member 150 when the driving device 140 drives the air flow pushing component 120 to move from the second position to the first position.

[0076] In this embodiment, by reciprocally moving the air flow pushing component 120 between the first position and the second position, when the air flow pushing component 120 moves from the first position to the second position, it gradually moves away from the air outlet 112a, so that the side of the housing 110 close to the air outlet 112a is filled with gas. Subsequently, when the air flow pushing component 120 quickly moves from the second position to the first position, it squeezes the gas in the housing 110, and the vortex ring air flow is sent out from the air outlet 112a. It can be understood that the first position is located on the thrust portion 113.

[0077] The shapes, sizes, and numbers of the first magnetic member 150 and the second magnetic member 160 may be the same or different. The numbers of the first magnetic member 150 and the second magnetic member 160 may be multiple, or may be a circular magnetic strip. The first magnetic member 150 and the second magnetic member 160 may be magnetic blocks, such as circular magnetic blocks, square magnetic blocks, etc., and the first magnetic member 150 and the second magnetic member 160 may also be magnetic strips, such as rectangular magnetic strips, arc-shaped magnetic strips, etc. By making the first magnetic member 150 and the second magnetic member 160 be arc-shaped magnetic strips, the arc-shaped magnetic strips are adapted to the circular arc-shaped peripheries of the housing 110 and the air flow pushing component 120, thereby maintaining the overall appearance consistency. The first magnetic member 150 and the second magnetic member 160 may be permanent magnets or may be electromagnets. For the sake of simplifying the structure and saving costs, the first magnetic member 150 and the second magnetic member 160 are preferably permanent magnets. The first magnetic member 150 may be bonded to the air flow pushing component 120 with glue, or a groove may be formed on the air flow pushing component 120, and the first magnetic member 150 may be embedded in the groove. The second magnetic member 160 may be directly attached to the inner wall surface of the housing 110, or an installation structure may be provided on the inner wall surface of the housing 110 for installing the second magnetic member 160.

[0078] It can be understood that the opposite ends of the first magnetic member 150 and the second magnetic member 160 have the same magnetic poles. Then, when the first magnetic member 150 and the second magnetic member 160 approach each other, they repel each other, thereby generating a repulsive force on the air flow pushing assembly 120. To ensure that the first magnetic member 150 and the second magnetic member 160 generate a repulsive force for interaction, the positions of the first magnetic member 150 and the second magnetic member 160 should be correspondingly arranged. The second magnetic member 160 is installed on the housing 110 between the air supply port 112a and the first position. Then, when the air flow pushing assembly 120 moves from the second position to the side close to the air supply port 112a and reaches a position close to the second magnetic member 160, the second magnetic member 160 generates a repulsive force on the first magnetic member 150 towards the second position. And when the air flow pushing assembly 120 moves to the first position, that is, on the thrust portion 113, the sum of this repulsive force and the thrust force of the thrust portion 113 on the air flow pushing assembly 120 is equal to the driving force that drives the air flow pushing assembly 120 to move towards the side close to the air supply port 112a, so that the air flow pushing assembly 120 stops at the first position. The number and size of the second magnetic member 160 and the first magnetic member 150 can be designed according to the distance between the first position and the installation position of the second magnetic member 160, and no specific limitation is made here.

[0079] By arranging the first magnetic member 150 on the air flow pushing assembly 120 and arranging the second magnetic member 160 on the housing 110 between the air supply port 112a and the first position, when the driving device 140 drives the air flow pushing assembly 120 to move from the second position to the first position, a repulsive force towards the second position is generated on the first magnetic member 150. Thus, the air flow pushing assembly 120 is subjected to a repulsive force when moving from the second position to the first position. Combining with the thrust action of the thrust portion 113 on the air flow pushing assembly 120, the air flow pushing assembly 120 stops moving. This kind of stop limiting method makes the resistance that the air flow pushing assembly 120 receives gradually increase when moving towards the side close to the air supply port 112a, thereby slowly stopping the air flow pushing assembly 120. Compared with the air flow pushing assembly 120 directly colliding with other media to stop, it can reduce or avoid the generation of noise and improve the user's comfort.

[0080] In one embodiment, please refer to Figure 2 and Figure 3 , 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 supply port 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 move back towards the side close to the air supply port 112a.

[0081] 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 component 120, so that when the air flow pushing component 120 is closest to the air supply port 112a, the flexible belt 143 can pull the air flow pushing component 120 to gradually move away from the air supply port 112a. The flexible belt 143 refers to a belt-shaped 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, stable, and has the ability of buffering and vibration reduction, thereby further reducing noise. One end of the flexible belt 143 can be fixed on the air flow pushing component 120 by means of welding, clamping, screw connection, bonding, etc. The reset member 144 can specifically be a structure such as a compression spring that can drive the air flow pushing component 120 to move in the reset direction.

[0082] The driving member 141 can be a driving cylinder, a driving motor, etc. The driving motor has the advantages of 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. Then, when the driving motor is powered on, it drives the wire wheel 142 to rotate forward to wind the flexible belt 143. When the driving motor is powered off, the wire wheel 142 can rotate reversely under a small driving force, and then the flexible belt 143 can be stretched out from the wire wheel 142 when the air flow push plate assembly moves in the reset direction. By arranging 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 easy to shift, so that the contraction and extension of the flexible belt 143 are easy. When the driving member 141 works, the driving force is greater than the reset force of the reset member 144, so that the flexible belt 143 can be wound by the wire wheel 142 to pull the air flow pushing component 120 to move toward the side away from the air supply port 112a. When the driving member 141 stops working, the driving force disappears, and the reset force of the reset member 144 drives the air flow pushing component 120 to quickly move in the reset direction toward the side close to the air supply port 112a, and at the same time drives the flexible belt 143 to stretch. In this way, the air flow pushing component 120 can be reciprocally moved periodically along the axis of the housing 110.

[0083] The driving member 141 drives the wire wheel 142 to wind the flexible belt 143, driving the air flow pushing assembly 120 to move toward the side away from the air supply port 112a. The reset member 144 drives the air flow pushing assembly 120 to move toward the side close to the air supply port 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, thus greatly improving the user experience.

[0084] The present invention also provides an indoor air conditioner. Please refer to Figure 11 and 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 embodiments. Since this indoor 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 here one by one. The vortex ring generating device 100 can be specifically installed on the housing 200 or inside the housing 200. And the air duct of the vortex ring generating device 100 can be connected or not connected to the heat exchange air duct 210 inside the housing 200. 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.

[0085] In one embodiment, please refer to Figure 11 and Figure 12 again. 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 port 112a of the vortex ring generating device 100 is communicated with the room through the installation opening 220.

[0086] The indoor air conditioner further includes a guiding member 300 connected to the air supply port 112a. The guiding member 300 is arranged around the air supply port 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 is communicated 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 port 112a.

[0087] 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. The air supply opening 112a is in communication with the interior through the installation opening 220, so the flow collector 112 can be arranged inside the housing 110 such that the air supply opening 112a corresponds to the vortex ring air outlet; or the flow collector 112 can be abutted against the panel, that is, the vortex ring air outlet is connected to the air supply opening 112a; or the flow collector 112 can be extended out of the panel such that the air supply opening 112a is located outside the panel.

[0088] The flow guide member 300 is arranged around the air supply opening 112a, and the flow guide member 300 can be connected to the outer peripheral side wall of the flow collector 112. Through the action of the flow guide member 300, the air flow on the outer peripheral side wall of the flow collector 112 can be smoothly guided to deviate from the direction of the vortex ring air flow blowing out, thereby avoiding the air flow blown out from the air dispersion air outlet passage 230 from affecting the formation and air supply of the vortex ring air flow. The flow guide member 300 can be arranged inside the housing 200, or extended out of the housing 200, or flush with the housing 200. When the flow guide member 300 is arranged inside the housing 200 or flush with the housing 200, the radial dimension of the air outlet of the flow guide member 300 should be smaller than the radial dimension of the installation opening 220, so as to smoothly form the air dispersion air outlet passage 230 between the outer wall surface of the flow guide member 300 and the inner wall surface of the installation opening 220.

[0089] The flow guide member 300 and the flow 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 flow 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 installation opening 220 should be smaller than the radial dimension of the installation opening 220, so that a vortex ring air outlet is formed in the middle of the installation opening 220, and an air dispersion air outlet passage 230 is formed around. When the flow guide member 300 and the flow collector 112 are separately formed, the flow guide member 300 extends out of the housing 200, and the flow collector 112 of the vortex ring generating device 100 is arranged inside the housing 110. The air supply opening 112a is located inside the panel. At this time, the radial dimension of the position of the flow guide member 300 corresponding to the installation opening 220 should be smaller than the radial dimension of the installation opening 220, so that the flow guide member 300 and the inner wall surface of the installation opening 220 enclose to form the air dispersion air outlet passage 230. The air flow blown out from the air dispersion air outlet passage 230 can achieve draft-free air supply, the air supply is softer, and the comfort is higher.

[0090] 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 disposed within the housing 200, the overall form of the flow guide cylinder can be gradually expanding from the inside to the outside, or the form of the flow guide plate can be gradually expanding 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 the form of a straight plate. In this way, the flow guide cylinder is connected to the flow collecting member 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 passage 230 to the direction of the vortex ring air flow blown out away from the air supply port 112a, so that the air flow blown out from the diffused air outlet passage 230 does not affect the vortex ring air flow. At this time, the flow guide cylinder and the flow collecting member 112 can be integrally provided without a connecting wire, and the flow guide cylinder can also be in the shape of a straight cylinder.

[0091] The heat exchange air duct 210 refers to a passage where the air flow entering from the main air inlet can exchange heat therein 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 provided 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 within the housing 200. The cross-sectional shape of the housing 200 and the heat exchange air duct 210 can be circular, elliptical, rectangular, polygonal, etc. The extending shape of the heat exchange air duct 210 can be a straight cylinder type or a bent type, etc.

[0092] The air conditioner indoor unit of the present invention sets a flow guide member 300 at the air supply port 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 blown out. In this way, the mounting opening 220 provided 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, and 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, has 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, the heat exchange efficiency is high, the space temperature is more uniform, and the comfort level is higher.

[0093] 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.

[0094] 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 opened on one of the side plates, or main air outlets can be opened on both side plates. In order to make the air outlet range wider and the air outlet area larger, it is preferably to open main air outlets on both side plates. The shape of the main air outlet can be circular, oval, strip-shaped, etc. In order to make the air volume larger, it is preferably strip-shaped. The panel and the two side plates can be integrally formed or separately formed. An air inlet is also opened 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 opened on the panel and / or the two side plates, or can also be opened on the rear panel of the housing 200. By opening the main air outlet on the side plate, the air flow of conventional air supply will not affect the vortex ring air flow. While making the air outlet area wide, the air supply distance far, and the air supply form diverse, the air flow transmission efficiency is high, thereby improving the heat exchange efficiency of the room, making the temperature of the space more uniform, and further improving the comfort. Conventional air supply and vortex ring air supply can be turned on simultaneously or separately.

[0095] The present invention also provides an air conditioner, which includes an air conditioner indoor unit and an air conditioner outdoor unit connected by a refrigerant pipe. Among them, the air conditioner indoor unit includes a vortex ring generating device 100. The specific structure of the vortex ring generating device 100 refers to the above-mentioned embodiments. Since the air conditioner indoor unit 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.

[0096] 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 by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
