[0040] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0042] It should be noted that if directional indicators (such as up, down, left, right, front, back, etc.) are involved in the embodiments of the present invention, these directional indicators are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicators will also change accordingly. Furthermore, the meaning of "and / or" throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that satisfies both A and B.

[0043] This invention proposes a vortex ring generator and an indoor air conditioning unit incorporating the vortex ring generator. The vortex ring generator periodically drives airflow through an air outlet to form a vortex ring airflow, delivering the air in a circular manner to the far end of the room. With the same airflow volume, the vortex ring generator can blow the air further, resulting in a longer air delivery distance and a wider radiation range.

[0044] Please see Figures 1 to 5This invention proposes a vortex ring generator 100, which includes a housing 110, a vortex ring generating part 140, a driving device 150, and a resetting member 170. The housing 110 includes a duct 120 and a collector 130. One end of the duct 120 is provided with a first air outlet 122. The collector 130 is installed at the first air outlet 122 and has an air supply port 131 communicating with the duct 120. The air passage area of ​​the air supply port 131 is smaller than the air passage area of ​​the first air outlet 122. The vortex ring generating part 140 is installed inside the housing 110 and includes a vortex ring generating element. The vortex ring generating element can periodically drive airflow through the air supply port and has a first magnetic suction member 154. The driving device 150 is provided with a second magnetic member 155 that magnetically engages with the first magnetic member 154; one end of the reset member 170 is connected to the vortex generator, and the other end is connected to the housing 110. The driving device 150 is used to drive the vortex generator to move away from the air outlet 131 when the force applied by the reset member 170 to the vortex generator is less than the magnetic attraction force between the first magnetic member 154 and the second magnetic member 155; the reset member 170 is used to drive the vortex generator to move closer to the air outlet 131 when the force applied by the reset member 170 to the vortex generator is greater than the magnetic attraction force between the first magnetic member 154 and the second magnetic member 155.

[0045] In this embodiment of the invention, the air duct 120 is generally cylindrical. The air duct 120 includes a bottom wall and a peripheral wall. A first air inlet 121 is provided on the bottom wall and / or the peripheral wall. A first air outlet 122 is provided at one end of the air duct 120. The collector 130 is installed at the first air outlet 122 and is connected to the air duct 120. It is understood that, for ease of assembly and disassembly, the collector 130 and the air duct 120 can be integrally formed; however, they can also be separate components, such as by snap-fit ​​or screw connection.

[0046] The structure of the air collector 130 can vary, and no specific limitation is made here. For example, the air collector 130 can be a collector cylinder, which gradually narrows from the first air outlet 122 to the air supply outlet 131, thus making the air passage area of ​​the air supply outlet 131 smaller than that of the first air outlet 122. Another example is that the air collector 130 can be a collector plate, which is disposed at the first air outlet 122, and the air supply outlet 131 is opened on the collector plate, which also makes the air passage area of ​​the air supply outlet 131 smaller than that of the first air outlet 122.

[0047] By making the air passage area of ​​the air inlet 131 smaller than that of the first air outlet 122, part of the airflow flowing from the first air outlet 122 to the air inlet 131 will flow along the inner wall of the collector 130 and then out from the periphery of the air inlet 131, while the other part will flow out from the center of the air inlet 131. The part of the airflow flowing out from the edge of the air inlet 131 is defined as the edge airflow, and the part of the airflow flowing out from the center of the air inlet 131 is defined as the center airflow. The edge airflow is subject to resistance from the inner wall of the collector 130, resulting in a lower velocity compared to the center airflow. This velocity difference will cause a vortex-like airflow to be generated when the airflow flows out of the air inlet 131. Under the same air volume, the vortex-like airflow method can achieve directional, fixed-point, and long-distance air delivery. Furthermore, the vortex ring exchanges heat with the surrounding air during transmission, and the temperature difference between the vortex ring and the surrounding air is not large, ensuring that the vortex ring will not produce a noticeable feeling of being too cold or too hot when it blows on a person, thus improving comfort.

[0048] There can be various structures for the vortex generator. For example, in this embodiment, the vortex generator includes a flexible member 141 and a pusher plate 144. The outer edge of the flexible member 141 is connected to the inner peripheral wall of the housing 110, and the pusher plate 144 is mounted on the flexible member 141. The first magnetic suction member 154 is disposed on the pusher plate 144. In this embodiment, the vortex generator includes a flexible member 141 and a pusher plate 144, which can reduce noise generation and also quickly drive the vortex generator to move back and forth. Of course, it is understood that in other embodiments, the vortex generator may include either a flexible member 141 or a pusher plate 144, and the vortex generator can periodically drive airflow through the air outlet 131.

[0049] The flexible component 141 refers to a structure that can be easily deformed but is not easily damaged, possessing the characteristics of quick folding and stretching. The material of the flexible component 141 can be nylon, cotton, fiber, or other fabric materials; polyethylene, polypropylene, polyester, or other plastic materials; rubber, etc., without specific limitations. The flexible component 141 simply needs to be flexible, foldable, and stretchable. The outer periphery of the flexible component 141 is sealed to the inner peripheral wall of the housing 110. Specifically, the outer periphery of the flexible component 141 can be sealed to the inner peripheral wall of the air duct 120 or the outer peripheral wall of the collector 130. The flexible component 141 can be connected to the housing 110 by screws, adhesives, crimping, etc., without specific limitations. The flexible component 141 can be disposed within the air duct 120, within the collector 130, or at the connection point between the air duct 120 and the collector 130. To extend the moving path of the pusher plate 144 and improve the compression effect, the flexible component 141 can be positioned inside the air duct 120 near the first air outlet 122. The pusher plate 144 has a plate-like structure. To better drive the flexible component 141, the pusher plate 144 can be installed in the middle of the flexible component 141, but this is not a limitation. Furthermore, the pusher plate 144 and the flexible component 141 can be fixed in various ways, such as by bonding, pressing, or screw connection.

[0050] The vortex ring generator is provided with a first magnetic attractor 154, and the driving device 150 is provided with a second magnetic attractor 155 that magnetically engages with the first magnetic attractor 154. In this embodiment of the invention, the driving device 150 and the vortex ring generator are connected and fixed by the magnetic attraction between the first magnetic attractor 154 and the second magnetic attractor 155, so that the driving device 150 can drive the vortex ring generator to move away from the air outlet 131. It should be noted that during the process of the driving device 150 driving the vortex ring generator to move away from the air outlet 131, the force applied to the vortex ring generator by the reset member 170 continuously increases. When the force applied to the vortex ring generator by the reset member 170 is greater than the magnetic attraction between the first magnetic attractor 154 and the second magnetic attractor 155, the reset member 170 can drive the vortex ring generator to move closer to the air outlet 131.

[0051] It is worth mentioning that at least one of the first magnetic attractor 154 and the second magnetic attractor 155 is an electromagnet. In one embodiment, one of the first magnetic attractor 154 and the second magnetic attractor 155 is an electromagnet, and the other is a magnetically conductive material, such as a steel plate or iron plate. In this embodiment, when the electromagnet is energized, there is a magnetic attraction between the electromagnet and the magnetically conductive material. Furthermore, when the magnetic attraction between the electromagnet and the magnetically conductive material is greater than the force applied to the vortex ring generator by the reset member 170, the driving device 150 can drive the vortex ring generator to move away from the air outlet 131. When the electromagnet is de-energized, the magnetic attraction between the electromagnet and the magnetically conductive material disappears. At this time, the magnetic attraction between the electromagnet and the magnetically conductive material is zero, which is less than the force applied to the vortex ring generator by the reset member 170. At this time, the reset member 170 can drive the vortex ring generator to move closer to the air outlet 131. Of course, this is not the only option. In other embodiments, both the first magnetic member 154 and the second magnetic member 155 may be electromagnets.

[0052] The vortex ring generator 100 of the present invention includes a vortex ring generating part 140, a driving device 150, and a resetting member 170. The vortex ring generating part 140 generates the vortex ring and can periodically drive airflow through the air outlet 131. A first magnetic attractor 154 is provided on the vortex ring generator. A second magnetic attractor 155 is provided on the driving device 150 to magnetically engage with the first magnetic attractor 154. One end of the resetting member 170 is connected to the vortex ring generator, and the other end is connected to the housing 110. Thus, the force exerted by the resetting member 170 on the vortex ring generator is small. When there is a magnetic attraction between the first magnetic member 154 and the second magnetic member 155, the driving device 150 drives the vortex ring generator to move away from the air outlet 131; when the force applied to the vortex ring generator by the reset member 170 is greater than the magnetic attraction between the first magnetic member 154 and the second magnetic member 155, the reset member 170 drives the vortex ring generator to move closer to the air outlet 131, thereby causing the airflow in the air duct 120 to be blown out of the air outlet 131 and form a vortex ring, realizing vortex ring air delivery, with a longer delivery distance and a wider radiation range.

[0053] Please see Figure 5 and Figure 6In one embodiment, the driving device 150 is used to drive the vortex generator to move away from the air outlet 131 when the first magnetic member 154 and the second magnetic member 155 are in contact. The resetting member 170 is used to drive the vortex generator to move closer to the air outlet 131 when the first magnetic member 154 and the second magnetic member 155 are separated. Optionally, the resetting member 170 is used to drive the vortex generator to move closer to the air outlet 131 when the magnetic attraction force between the first magnetic member 154 and the second magnetic member 155 is zero.

[0054] Please see Figure 5 and Figure 6 In one embodiment, the driving device 150 includes a motor 151, a gear 152, and a rack 153. The motor 151 is mounted on the air duct 120, the gear 152 is mounted on the motor shaft of the motor 151, and the rack 153 extends axially along the air duct 120 and meshes with the gear 152. The second magnetic suction member 155 is mounted on the end of the rack 153 near the first magnetic suction member 154. Specifically, a mounting structure is provided at the end of the rack 153 near the first magnetic suction member 154, and the second magnetic suction member 155 is mounted on the mounting structure. The specific structure of the mounting structure is not limited and can be a mounting base, mounting plate, or mounting bracket, etc.

[0055] In this embodiment, the motor 151 drives the gear 152 to rotate, and the gear 152 meshes with the rack 153, thereby driving the rack 153 to move along the axial direction of the air duct 120. The movement of the rack 153 in turn drives the second magnetic suction member 155 to move. When the magnetic attraction force between the first magnetic attractor 154 and the second magnetic attractor 155 is greater than the force applied to the push plate 144 by the reset member 170, the first magnetic attractor 154 and the second magnetic attractor 155 are in contact, and the motor 151 can drive the vortex ring generator to move away from the air outlet 131 through the meshing of the gear 152 and rack 153; when the magnetic attraction force between the first magnetic attractor 154 and the second magnetic attractor 155 is less than the force applied to the push plate 144 by the reset member 170, in particular, when the magnetic attraction force between the first magnetic attractor 154 and the second magnetic attractor 155 is zero, the reset member 170 can drive the vortex ring generator to move towards the air outlet 131.

[0056] The vortex generator (push plate 144) driven by the reset component 170 moves toward the air outlet 131. Compared with the motor 151 driving the vortex generator toward the air outlet 131, the pushing speed is faster, and the push plate 144 can be reset to the initial position more accurately, resulting in a better reset effect. The speed requirement of the motor 151 is also lower, making the overall design more reasonable.

[0057] Please see Figure 6 In one embodiment, the first magnetic attractor 154 is a steel plate, and the second magnetic attractor 155 is an electromagnet. The electromagnet is a DC electromagnet. When the electromagnet is energized, a magnetic attraction force is generated between the first magnetic attractor 154 and the second magnetic attractor 155. When the electromagnet is de-energized, the magnetic attraction force between the first magnetic attractor 154 and the second magnetic attractor 155 disappears.

[0058] To mount the first magnetic member 154 onto the push plate 144, a mounting groove 147 can be provided on the push plate 144, and the first magnetic member 154 is mounted in the mounting groove 147. Specifically, the mounting groove 147 is formed by a recess in the push plate 144 towards the side near the air outlet 131. The formation of the mounting groove 147 is not specifically limited; its shape only needs to be adapted to the shape of the first magnetic member 154.

[0059] In order to better fix the first magnetic suction member 154 in the mounting groove 147 and prevent the first magnetic suction member 154 from separating from the push plate 144, the vortex ring generator 100 further includes a fixing frame 160, which is detachably installed in the groove of the mounting groove 147 to fix the first magnetic suction member 154 in the mounting groove 147.

[0060] Specifically, the fixing bracket 160 includes a fixing part 161, which abuts against the first magnetic attractor 154, and a through hole is provided through the fixing part 161. It should be noted that the fixing part 161 can be plate-shaped, column-shaped, or other irregularly shaped. The through hole in the fixing part 161 allows the first magnetic attractor 154 and the second magnetic attractor 155 to directly contact each other, thereby increasing the magnetic attraction between them. Of course, the fixing part 161 may also omit the through hole.

[0061] Furthermore, the fixing frame 160 also includes a guide portion 162 disposed on the side of the fixing part 161 away from the first magnetic member 154. The guide portion 162 forms a guide groove 163 extending axially along the air duct 120. The opening of the guide groove 163 is disposed away from the air outlet 131. The second magnetic member 155 moves towards the air outlet 131 under the drive of the reset member 170, and can enter the guide groove 163 through the opening of the guide groove 163, thereby ensuring that the second magnetic member 155 and the first magnetic member 154 are accurately aligned, thus better exerting the magnetic attraction function. In one embodiment, in order to allow the second magnetic member 155 to enter the guide groove 163 better, the guide groove 163 can be flared in the direction from the first magnetic member 154 toward the second magnetic member 155.

[0062] In the above embodiments, the structure of the flexible member 141 is not specifically limited. For example, in one embodiment, when the flexible member 141 is in its natural state, it is arranged in a ring shape, and the push plate 144 is installed in the inner hole of the flexible member 141 and connected to the inner edge of the flexible member 141. Specifically, the push plate 144 is sealed to the inner edge of the flexible member 141. Utilizing the deformable properties of the flexible member 141, the push plate 144 can move back and forth while ensuring sealing, thereby periodically compressing the gas inside the air duct 120 to generate a vortex airflow; at the same time, it can also reduce noise.

[0063] Please see Figure 6 and Figure 7 In another embodiment, when the flexible member 141 is in its natural state, it is cylindrical and has a first end 142 and a second end 143. The pusher plate 144 is mounted on the first end 142, and the second end 143 is connected to the housing 110 and is open. The flexible member 141 gradually expands from the first end 142 to the second end 143. The first end 142 of the flexible member 141 can be open or closed, without specific limitation. In this embodiment, by making the flexible member 141 cylindrical, the forward and backward movement distance of the pusher plate 144 can be increased, resulting in better compression of the gas inside the housing 110 by the pusher plate 144, thereby increasing the vortex ring's air delivery distance. Optionally, the flexible member 141 can be a corrugated cylindrical structure.

[0064] For the flexible component 141 with a cylindrical structure, in order to facilitate the installation and fixation of the flexible component 141, a first mounting ring 145 can be provided at the first end 142 of the flexible component 141, and a second mounting ring 146 can be provided at the second end 143 of the flexible component 141. The first mounting ring 145 is connected to the push plate 144, and the second mounting ring 146 is connected to the inner peripheral wall of the housing 110. In this embodiment, the first mounting ring 145 and the second mounting ring 146 can be made of hard materials such as hard plastic or hard rubber.

[0065] In one embodiment, the cross-sectional area of ​​the pusher plate 144 is greater than or equal to the air passage area of ​​the air outlet 131. It is understood that the drive device 150 moves the pusher plate 144 along the axial direction of the air duct 120, causing disturbance to the gas within the air duct 120. Furthermore, when the pusher plate 144 moves towards the air outlet 131, it can expel the gas from the air duct 120 through the air outlet 131. Therefore, the cross-sectional area of ​​the pusher plate 144 significantly affects the gas delivery speed and the degree of disturbance. By making the cross-sectional area of ​​the pusher plate 144 larger than the air passage area of ​​the air outlet 131, a sufficiently large effective area of ​​the pusher plate 144 can be ensured, thereby increasing the gas velocity and flow rate blown out of the air outlet 131, allowing the vortex ring to blow further and radiate over a wider range.

[0066] In the above embodiments, the reset member 170 is a spring, but it is not limited to this. A guide rod 171 extending axially along the air duct 120 is provided on the air duct 120, and a mounting hole for mounting the guide rod 171 is provided on the push plate 144. The spring is sleeved on the guide rod 171. In this embodiment, by sleeved on the guide rod 171, the guide rod 171 acts as a support and guide, thereby guiding the movement of the push plate 144.

[0067] Furthermore, there are multiple guide rods 171, which are spaced apart circumferentially along the push plate 144. The multiple guide rods 171 can be evenly spaced along the circumference of the push plate 144, but are not limited to this. Corresponding to the number of guide rods 171, there are also multiple springs. The arrangement of multiple guide rods 171 and multiple springs improves the guiding and resetting effect.

[0068] In one embodiment, the vortex ring generator 140 further includes a clamping member connected to the push plate 144. The flexible member 141 is sandwiched between the push plate 144 and the clamping member. The guide rod 171 passes through the clamping member, and the end of the spring near the clamping member is connected to the clamping member. By connecting the clamping member to the push plate 144 and clamping the flexible member 141 between them, the connection between the flexible member 141 and the push plate 144 is made more stable. Furthermore, during movement, the clamping member drives the push plate 144 to move axially along the guide rod 171 and compresses the spring, increasing the contact area with the guide rod 171 and making the guidance more stable. The clamping member can be a pressure ring or a pressure plate; to reduce the weight of the entire vortex ring generator 140, the clamping member is designed as a pressure ring.
