Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a vortex generator, an indoor air conditioning unit, and an air conditioner. Background Technology

[0002] Current air conditioners typically use a conventional air delivery method, blowing the heat-exchanged air directly out through the standard vents. This method produces a continuous airflow over a short distance. Related technologies suggest that installing a vortex generator on the air conditioner can achieve long-distance air delivery. Traditional vortex generators generally consist of a pusher plate within the housing cavity. This pusher plate, driven by a mechanism, can move closer to or further away from the air outlet. When the pusher plate moves away from the air outlet, it causes airflow retraction at the outlet, leading to airflow turbulence within the cavity and insufficient negative pressure replenishment. This results in unstable vortex formation and a low vortex generation frequency. Summary of the Invention

[0003] The main objective of this invention is to provide a vortex ring generating device that aims to ensure the stability of vortex ring formation and increase the vortex ring generation frequency.

[0004] To achieve the above objectives, the vortex ring generator proposed in this invention includes:

[0005] The housing has an air inlet, an air outlet, and a cavity connecting the air inlet and the air outlet;

[0006] A push plate is movably disposed within the cavity and is positioned opposite to the air outlet. The push plate includes a push plate body and a switch door. The push plate body has air outlets that pass through both sides, and the switch door is movably connected to the push plate body.

[0007] A switching power component, connected to the door drive, is used to drive the door to open or close the air vent; and

[0008] A drive mechanism is connected to the pusher plate body and is used to drive the pusher plate body to move closer to or away from the air outlet.

[0009] In one embodiment, the switch door is rotatably connected to the push plate body, and the switch power component is used to drive the switch door to rotate relative to the push plate body to open or close the air vent.

[0010] In one embodiment, the switch door includes at least two louvers and a connecting rod connecting each of the louvers. Each of the louvers is rotatably connected to the push plate body. The switch power component is used to drive at least one of the louvers to rotate, thereby driving the other louvers to move in tandem.

[0011] In one embodiment, the opening angle of each louver is 0° to 180°.

[0012] In one embodiment, the push plate body includes a support frame, the inner periphery of the support frame encloses to form the air vent, the outer periphery of the support frame is disposed near the inner periphery of the cavity, and the opposite sides of the switch door are rotatably connected to the inner periphery of the support frame.

[0013] In one embodiment, the push plate body further includes a support strip, the two ends of which are respectively connected to the support frame.

[0014] In one embodiment, the driving mechanism includes a driving member and a transmission assembly. The driving member has a rotary output shaft, which is connected to the push plate via the transmission assembly. The transmission assembly is used to convert the rotational driving force of the rotary output shaft into a driving force that causes the push plate to perform linear reciprocating motion.

[0015] In one embodiment, the push plate further includes a push-pull shaft connected to the push plate body, and the transmission assembly includes a first connecting rod, a second connecting rod, and a fixed sliding sleeve. One end of the first connecting rod is connected to the rotary output shaft, the other end of the first connecting rod is movably connected to one end of the second connecting rod, and the other end of the second connecting rod is movably connected to the push-pull shaft. The push-pull shaft slidably passes through the fixed sliding sleeve.

[0016] The present invention also proposes an indoor air conditioning unit, including a casing and a vortex generator as described above disposed in the casing, wherein the air outlet of the vortex generator corresponds to and is connected to the air outlet of the casing, and the air inlet of the vortex generator is connected to the heat exchange air duct; or the air inlet of the vortex generator is connected to the atmosphere.

[0017] The present invention also proposes an air conditioner, including an outdoor unit and an indoor unit as described above, wherein the outdoor unit and the indoor unit are connected by a refrigerant pipe.

[0018] The technical solution of this invention movably mounts a pusher plate within the cavity of the housing. The pusher plate includes a pusher plate body and a switch door movably connected to the pusher plate body. A switching power component drives the switch door to open or close the air inlet, and a driving mechanism drives the pusher plate body to move closer to or away from the air outlet. When the pusher plate body moves towards the air outlet, the switching power component drives the switch door to close the air inlet, thereby blocking the airflow on both sides of the pusher plate. Since the air in the front cavity in front of the pusher plate is compressed, the air pressure in the front cavity is significantly greater than the air pressure in the rear cavity behind the pusher plate. The air in the front cavity tends to move towards the rear cavity. The switch door closes the air inlet during the forward push, preventing the airflow from the side with higher air pressure to the side with lower air pressure. This ensures that the airflow in the cavity can be pushed towards the air outlet as much as possible to form a vortex ring during the forward push of the pusher plate. When the pusher plate moves away from the air outlet, the switching mechanism drives the switch door to open the air passage. At this time, the air pressure in the rear cavity of the pusher plate is significantly greater than that in the front cavity. Opening the air passage utilizes the pressure difference to allow the airflow from the rear of the pusher plate to flow into the front cavity. This enables rapid replenishment of airflow in the cavities on both sides of the pusher plate, reducing airflow turbulence caused by the backflow of air from the air outlet due to the pusher plate moving backward and insufficient replenishment of negative pressure airflow in the cavity. This ensures the stability of vortex ring formation and increases the vortex ring generation frequency to meet the vortex ring air supply requirements of different groups and frequencies. When the pusher plate moves to the end of the cavity away from the air outlet, the switching mechanism drives the switch door to close the air passage again, and then the drive mechanism drives the pusher plate forward. This cycle repeats continuously, enabling the vortex ring to be continuously output from the air outlet. Attached Figure Description

[0033] This invention proposes a vortex ring generator 100. This vortex ring generator 100 can be applied to air conditioning equipment such as air conditioners, air purifiers, and humidifiers. For example, in this embodiment, the vortex ring generator 100 is applied to an air conditioner, specifically, as... Figure 1 As shown, the vortex generator 100 is installed inside the casing 210 of the indoor unit 200 of the air conditioner. The air outlet 12 of the vortex generator 100 corresponds to and is connected to the air outlet of the indoor unit 200. The vortex generator 100 can periodically drive the airflow through the air outlet to form a vortex airflow, which can achieve long-distance air delivery and a wider radiation range.

[0034] Please refer to Figures 2 to 5 In one embodiment of the present invention, the vortex ring generator 100 includes a housing 10, a pusher plate 20, and a drive mechanism 30. The housing 10 has an air inlet 11, an air outlet 12, and a cavity 13 connecting the air inlet 11 and the air outlet 12; the pusher plate 20 is movably disposed in the cavity 13 and is disposed opposite to the air outlet 12; the pusher plate 20 includes a pusher plate body 21 and a switch door 22; the pusher plate body 21 has air passages 201 extending through both sides; the switch door 22 is movably connected to the pusher plate body 21; the switch power component is drivenly connected to the switch door 22 to drive the switch door 22 to open or close the air passages 201; the drive mechanism 30 is drivenly connected to the pusher plate body 21 to drive the pusher plate body 21 to move closer to or away from the air outlet 12.

[0035] Specifically, such as Figure 3 As shown, in this embodiment, the housing 10 includes a duct and a collector at one end of the duct. The collector is connected to the duct. The end of the collector away from the duct has an air outlet 12, and the end of the duct away from the collector has an air inlet 11. The collector can be a tapered collector tube, with its wide end connected to the duct and its narrow end having the air outlet 12. Alternatively, in other embodiments, the collector can be a collector plate at the port of the duct, with the air outlet 12 formed on the collector plate. To facilitate the generation of vortex rings, the cross-sectional area of ​​the air outlet 12 is typically set smaller than that of the duct. The duct and the collector can be integrally formed or separately formed and then assembled. The cross-sectional shapes of the air inlet 11, the air outlet 12, and the cavity 13 can be circular, elliptical, square, rectangular, or other irregular shapes as needed, and are not specifically limited here.

[0036] In this embodiment, the housing 10 extends in a front-to-back direction. The end of the housing 10 with the air outlet 12 is the front end, and the end with the air inlet 11 is the rear end. The push plate 20 is disposed within the cavity 13 and can reciprocate along the axial direction (i.e., the front-to-back direction) of the cavity 13 under the action of the drive mechanism 30. Of course, in other embodiments, the housing 10 can also be configured to extend left and right as needed, with the air outlet 12 disposed on the left or right side of the housing 10, and correspondingly, the push plate 20 can reciprocate in the left-to-right direction; or the housing 10 can be configured to extend up and down, with the air outlet 12 disposed on the upper or lower side of the housing 10, and correspondingly, the push plate 20 can reciprocate in the up-down direction. For ease of explanation, the following embodiments mainly use the example of the push plate 20 reciprocating in the front-to-back direction. In addition, the push plate 20 can be configured as circular, square, rectangular, fan-shaped, or other shapes as needed, and is not specifically limited here.

[0037] A push plate 20 is disposed within the cavity 13 and opposite to the air outlet 12. The push plate 20 includes a push plate body 21 and a switch door 22 movably connected to the push plate body 21. The outer peripheral surface of the push plate body 21 is positioned close to the inner peripheral surface of the cavity 13. The smaller the gap between the outer peripheral surface of the push plate body 21 and the inner peripheral surface of the cavity 13, the better, to reduce air leakage. However, in practical applications, considering that the push plate body 21 needs to reciprocate within the cavity 13, to ensure the smooth movement of the push plate body 21 and minimize air leakage as much as possible, optionally, the gap between the outer peripheral surface of the push plate body 21 and the inner peripheral surface of the cavity 13 is less than or equal to 5 mm. The push plate body 21 is provided with an air passage 201, which extends along the thickness direction of the push plate body 21 to opposite sides.

[0038] The switch door 22 is movably connected to the push plate body 21, including but not limited to rotational connection, sliding connection, or other movable connection methods. For example, when the switch door 22 is rotatably connected to the push plate body 21, the switching power component drives the switch door 22 to rotate relative to the push plate body 21 to open or close the air vent 201; when the switch door 22 is slidably connected to the push plate body 21, the switching power component drives the switch door 22 to slide relative to the push plate body 21 to open or close the air vent 201. The switching power component includes, but is not limited to, using linear power components (e.g., electric push rods) or rotary power components (e.g., drive motors) to drive the switch door 22 to open and close; or the switching power component may also use a gear transmission structure, synchronous belt pulley transmission structure, crankshaft connecting rod transmission structure, etc., to drive the switch door 22 to open and close, without specific limitations. Furthermore, the number of air vents 201 on the push plate body 21 can be set according to actual needs, and can be one, two, three, or more, correspondingly, the number of switch doors 22 is adapted to the number of air vents 201.

[0039] The drive mechanism 30 is used to drive the push plate body 21 to reciprocate linearly along the axial direction of the cavity 13 to move closer to or away from the air outlet 12. The specific form of the drive mechanism 30 is not limited. For example, the drive mechanism 30 can use a linear drive component (such as an electric push rod, linear motor, etc.) to directly drive the push plate body 21 to perform linear reciprocating motion; or the drive mechanism 30 can also use a rotary drive component in conjunction with a transmission assembly to drive the push plate body 21 to perform linear reciprocating motion; the transmission assembly includes, but is not limited to, a lead screw, ball screw, gear rack, or crank connecting rod, etc.

[0040] The technical solution of the present invention movably mounts the push plate 20 within the cavity 13 of the housing 10. The push plate 20 includes a push plate body 21 and a switch door 22 movably connected to the push plate body 21. The switch door 22 is driven to open or close the air outlet 201 by a switch power component, and the push plate body 21 is driven to move closer to or away from the air outlet 12 by a drive mechanism 30. Figure 4 As shown, when the pusher plate body 21 moves towards the air outlet 12, the switching power component drives the switch door 22 to close the air outlet 201, thus blocking the airflow on both sides of the pusher plate 20. Because the air in the front cavity in front of the pusher plate 20 is compressed, the air pressure in the front cavity is significantly greater than the air pressure in the rear cavity behind the pusher plate 20. The air in the front cavity tends to move towards the rear cavity. The switch door 22 closes the air outlet 201 during the forward push, preventing the airflow from the side with higher air pressure to the side with lower air pressure. This ensures that the pusher plate 20 can push the airflow in the cavity 13 towards the air outlet 12 as much as possible to form a vortex ring during its forward movement. Figure 5 As shown, when the push plate body 21 moves away from the air outlet 12, the switching power component drives the switch door 22 to open the air passage 201. At this time, the air pressure in the rear cavity of the push plate 20 is significantly greater than that in the front cavity. Opening the air passage 201 allows the air pressure difference to allow the airflow from the rear of the push plate 20 to flow through the air passage 201 to the front cavity of the push plate 20. This enables rapid replenishment of airflow in the front and rear cavities of the push plate 20, reducing airflow turbulence caused by the back suction of airflow from the air outlet 12 due to the rearward movement of the push plate 20 and insufficient replenishment of negative pressure airflow in the cavity 13. This ensures the stability of vortex ring formation and increases the generation frequency of vortex rings to meet the vortex ring air supply requirements of different groups and different frequencies. When the push plate 20 moves to the end of the cavity 13 away from the air outlet 12, the switching power component can drive the switch door 22 to close the air outlet 201 again, and then drive the push plate 20 forward through the drive mechanism 30. This cycle repeats, and the vortex ring can be continuously output from the air outlet 12.

[0041] There are various ways to connect the switch door 22 and the push plate body 21. In one embodiment, the switch door 22 and the push plate body 21 are rotatably connected, and the switching power component is used to drive the switch door 22 to rotate relative to the push plate body 21 to open or close the air vent 201. In this embodiment, the switch door 22 and the push plate body 21 are rotatably connected, which is a simple connection method and easy to install. For example, pivots can be provided on opposite sides of the switch door 22, and hooks for connecting the pivots can be provided on the push plate body 21. The switch door 22 can be in the form of a single door panel, a louvered door, or other forms, and is not specifically limited here.

[0042] Please refer to Figure 6 In one embodiment, the switchable door 22 includes at least two louvers 221 and a connecting rod 222 connecting each of the louvers 221. Each louver 221 is rotatably connected to the push plate body 21. The switching power component is used to drive at least one of the louvers 221 to rotate, thereby driving the other louvers 221 to move in tandem. Specifically, the specific number of louvers 221 can be set according to actual needs, and can be two, three, or more. The shapes of each louver 221 can be the same or different, as long as it is ensured that in the closed state, the shape formed by all the louvers 221 can block the air vent 201. The switching power component is used to drive one or more louvers 221 to rotate, thereby driving the other remaining louvers 221 to move in tandem.

[0043] For example, such as Figure 6 As shown, in this embodiment, the door 22 includes four louvers 221. The front sides of the four louvers 221 are connected by a connecting rod 222. The left and right sides of each louver 221 are rotatably connected to the two opposite side walls of the air vent 201. The switching power component can be a drive motor connected to the rotating shaft of one of the louvers 221. In this embodiment, power is transmitted between the louvers 221 through the connecting rod 222. The power is transmitted through the path of the switching power component—the active louver connected to the switching power component—the connecting rod 222—the passive louver not connected to the switching power component. The opening and closing actions of multiple louvers 221 can be realized through at least one switching power component, eliminating the need for a separate switching power component for each louver 221, reducing production and assembly costs, and providing excellent synchronization between the movements of each louver 221.

[0044] like Figure 4As shown, in the initial state, each louver 221 is generally perpendicular to the horizontal direction and assembled to form a vertically placed opening / closing door 22, which closes the air inlet 201. When the pusher plate body 21 moves towards the air outlet 12, the opening / closing door 22 remains in the closed position to block the airflow on both sides of the pusher plate 20. This ensures that as the pusher plate 20 moves forward, it can push the airflow in the cavity 13 towards the air outlet 12 as much as possible to form a vortex ring. Figure 5 As shown, when the push plate body 21 moves away from the air outlet 12, the switching power component drives one of the louvers 221 to rotate towards the side closer to the air outlet 12. Then, through the connecting rod 222, the remaining louvers 221 are driven to rotate synchronously towards the side closer to the air outlet 12, so that the airflow on the rear side of the push plate 20 can flow through the air outlet 201 to the cavity on the front side of the push plate 20. This enables the airflow in the cavities on both the front and rear sides of the push plate 20 to be quickly replenished, reducing the airflow turbulence caused by the airflow being drawn back from the air outlet 12 due to the push plate 20 moving backward and the phenomenon of insufficient replenishment of negative pressure airflow in the cavity 13. This ensures the stability of the vortex ring formation and increases the generation frequency of the vortex ring to meet the vortex ring air supply requirements of different groups of people and different frequencies. When the push plate 20 moves to the end of the cavity 13 away from the air outlet 12, the switching power component can drive one of the louvers 221 to rotate away from the air outlet 12. Then, through the connecting rod 222, it drives the remaining louvers 221 to rotate synchronously away from the air outlet 12 until the switch door 22 closes the air outlet 12 again. Then, the drive mechanism 30 drives the push plate 20 to move forward. This cycle repeats continuously, and the vortex ring can be continuously output from the air outlet.

[0045] Furthermore, the opening angle of each louver 221 is 0° to 180°. For example, in the closed position, the opening angle of each louver 221 is 0° to close the air vent 201. In the open position, each louver 221 rotates relative to the push plate body 21 to any angle between 0° and 180°, such as 60°, 90°, 120°, or 180°. Optionally, in the open position, each louver 221 rotates relative to the push plate body 21 to 90°, at which point each louver 221 is horizontally positioned, which reduces obstruction of the air vent 201.

[0046] There are various specific structures for the push plate body 21. In order to maximize the air passage area of ​​the air vent 201, such as... Figure 6As shown, in one embodiment, the push plate body 21 includes a support frame 211, the inner periphery of which encloses the air vent 201, and the outer periphery of the support frame 211 is disposed near the inner periphery of the cavity 13. The opposite sides of the switch door 22 are rotatably connected to the inner periphery of the support frame 211. In this embodiment, the support frame 211 has a ring-shaped structure, which allows the area of ​​the air vent 201 to be sufficiently large. The outer periphery of the support frame 211 is adapted to the shape of the inner periphery of the cavity 13. For example, in this embodiment, the inner periphery of the cavity 13 is circular, and correspondingly, the support frame 211 is set as a circular frame. Of course, in other embodiments, the support frame 211 can also be set as a square frame, a rectangular frame, or other irregularly shaped frames as needed. When the switch door 22 adopts a louvered door structure, the switch door 22 includes multiple louvers 221, and the opposite sides of each louver 221 are rotatably connected to the inner periphery of the support frame 211.

[0047] To enhance the structural strength of the pusher body 21, the pusher body 21 further includes a support strip 212, with both ends of the support strip 212 connected to the support frame 211. The specific number of support strips 212 can be set according to actual needs, and can be one, two, or more. For example, in this embodiment, there is one support strip 212, which is located inside the support frame 211 and can divide the support frame 211 into two halves. In this way, while ensuring the structural strength of the pusher body 21, the obstruction of the air vent 201 can be minimized.

[0048] To facilitate the connection between the push plate body 21 and the drive mechanism 30, the push plate 20 further includes a push-pull shaft 23. One end of the push-pull shaft 23 can be connected to the middle of the support bar 212, and the other end of the push-pull shaft 23 is used to connect to the drive mechanism 30. The drive mechanism 30 drives the push-pull shaft 23 to reciprocate along the axial direction, thereby driving the push plate 20 as a whole to perform reciprocating linear motion.

[0049] There are various specific implementations of the drive mechanism 30. In one embodiment, the drive mechanism 30 includes a drive member 31 and a transmission assembly. The drive member 31 has a rotary output shaft, which is connected to the push plate 20 via the transmission assembly. The transmission assembly is used to convert the rotary driving force of the rotary output shaft into a driving force that causes the push plate 20 to perform linear reciprocating motion.

[0050] In this embodiment, the rotational driving force output from the rotary output shaft of the drive component 31 is converted into linear driving force through a transmission assembly, thereby driving the airflow propulsion component to perform reciprocating linear motion. The transmission principle is simple and the transmission is reliable. The drive component 31 includes, but is not limited to, a drive motor or a rotary cylinder, as long as it can output rotational power. The transmission assembly includes, but is not limited to, a lead screw, a ball screw, a gear rack, or a crank connecting rod.

[0051] Please refer to Figure 2 and Figure 3 In one embodiment, the push plate 20 further includes a push-pull shaft 23 connected to the push plate body 21. The transmission assembly includes a first connecting rod 32, a second connecting rod 33, and a fixed sliding sleeve 34. One end of the first connecting rod 32 is connected to the rotary output shaft, and the other end of the first connecting rod 32 is movably connected to one end of the second connecting rod 33. The other end of the second connecting rod 33 is movably connected to the push-pull shaft 23, and the push-pull shaft 23 slidably passes through the fixed sliding sleeve 34. Specifically, the rotary output shaft of the drive member 31 drives the first connecting rod 32 and the second connecting rod 33 to rotate, thereby driving the push-pull shaft 23 to perform linear reciprocating motion along the slide groove of the fixed sliding sleeve 34. This, in turn, drives the push plate 20 to perform reciprocating linear motion along a preset direction via the push-pull shaft 23. The fixed sliding sleeve 34 guides the movement of the push-pull shaft 23, ensuring that the push plate 20 reciprocates along a preset path.

[0052] Please refer to Figure 1 The present invention also proposes an air conditioner indoor unit 200, which includes a housing 210 and a vortex generator 100 disposed within the housing 210. The vortex generator 100 includes a housing 10, a push plate 20, and a drive mechanism 30. The housing 10 has an air inlet 11, an air outlet 12, and a cavity 13 connecting the air inlet 11 and the air outlet 12; the push plate 20 is movably disposed within the cavity 13 and is disposed opposite to the air outlet 12; the push plate 20 includes a push plate body 21 and a switch door 22; the push plate body 21 has air passages 201 extending through both sides; the switch door 22 is movably connected to the push plate body 21; a switch power component is drivenly connected to the switch door 22 to drive the switch door 22 to open or close the air passages 201; the drive mechanism 30 is drivenly connected to the push plate body 21 to drive the push plate body 21 to move closer to or away from the air outlet 12. The air outlet 12 of the vortex ring generator 100 corresponds to and is connected to the air outlet of the housing 210.

[0053] In this embodiment, a vortex generator 100 is installed inside the casing 210 of the indoor unit 200 of the air conditioner. The vortex generator 100 can periodically output vortex airflow, which is blown out through the air outlet of the indoor unit 200. The vortex generator 100 can periodically drive the airflow through the air outlet to form a vortex airflow, enabling long-distance air delivery and a wider radiation range. Furthermore, when the vortex generator 100 is working, when the push plate body 21 moves towards the air outlet 12, the switching power component drives the switch door 22 to close the air outlet 201, thereby blocking the airflow on both sides of the push plate 20. This ensures that as the push plate 20 moves forward, it can push the airflow in the cavity 13 towards the air outlet 12 to form a vortex. When the pusher plate body 21 moves away from the air outlet 12, the switching power component drives the switching door 22 to open the air passage 201, allowing the airflow behind the pusher plate 20 to flow through the air passage 201 into the cavity in front of the pusher plate 20. This enables rapid replenishment of airflow in the cavities on both sides of the pusher plate 20, reducing airflow turbulence caused by the backflow of air from the air outlet 12 due to the pusher plate 20 moving backward, and reducing insufficient replenishment of negative pressure airflow in the cavity 13. This ensures the stability of vortex ring formation and increases the vortex ring generation frequency to meet the vortex ring air supply requirements of different groups and different frequencies. When the pusher plate 20 moves to the end of the cavity 13, the switching power component can drive the switching door 22 to close the air outlet 12 again, and then drive the pusher plate 20 forward through the drive mechanism 30. This cycle repeats continuously, enabling the vortex ring to be continuously output from the air outlet.
