[0046] Explanation of the reference numerals in the drawings:

[0047]

[0048] The realization of the object of the present invention, functional characteristics and advantages will be further described with reference to the embodiments and the accompanying drawings. Specific embodiments

[0049] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0050] In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution that satisfies both A and B at the same time.

[0051] The present invention provides a vortex ring generating device, which can be used alone or in air conditioners, air purifiers, humidifiers, fresh air fans, etc.

[0052] In the embodiment of the present invention, as Figures 1 to 8 shown, the vortex ring generating device 100 includes a housing 1 and a vortex ring generating part 2. The housing 1 includes a wind tube 11 and a flow collector 12. The wind tube 11 has an air inlet 111 and an air outlet 112. The flow collector 12 is installed at the air outlet 112. An air inlet 121 communicating with the wind tube 11 and a plurality of air outlets 122 are formed on the flow collector 12. The air passing area of each air outlet 122 is smaller than the air passing area of the air inlet 121. The vortex ring generating part 2 is installed on the housing 1. The vortex ring generating part 2 periodically drives the air flow to blow out through the flow collector 12, or the vortex ring generating part 2 periodically allows the air flow to pass through and blow out through the flow collector 12.

[0053] In this embodiment, the inner cavity of the housing 1 forms an air duct. The shape of the housing 1 can be a straight cylinder or a bent cylinder, and its cross-section can be rectangular, circular, oval, polygonal, irregular, etc., without specific limitation here. When the air outlet 112 and the air inlet 111 are oppositely arranged, the air duct is in a straight cylinder shape, with a small volume, small occupied space, small frictional resistance along the air flow, and more uniform and smooth air outlet. When the air outlet 112 and the air inlet 111 are not opposite, the air duct is in a bent shape. The overall shape and cross-sectional shape of the air duct can be selected according to the use requirements, without specific limitation here. An axial flow fan can also be arranged at the position corresponding to the air inlet 111 in the housing 1 to continuously introduce the air flow from the air inlet 111 into the housing 1. The shapes of the air outlet 112, the air inlet 111, the air inlet 121, and the air supply port 122 can be circular, rectangular, oval, polygonal, etc., or multiple micro-holes, without specific limitation here.

[0054] The current collector 12 and the air duct 11 can be integrally formed or separately formed. It can be understood that when the current collector 12 and the air duct 11 are separately formed, the current collector 12 and the air duct 11 are hermetically connected. When the current collector cover 123 and the air duct 11 are integrally formed, a virtual dividing line is defined with the connection between the air duct 11 and the current collector 12 as the boundary. One side of the dividing line is the air duct 11, and the other side is the current collector 12, and the air outlet 112 of the air duct 11 is formed at the dividing line. Undoubtedly, the air passing area of the air outlet 112 is larger than the air passing area of the air supply port 122 of the current collector 12. The extending directions of the outer wall surfaces of the current collector 12 and the air duct 11 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 connecting wire. The extending directions of the outer wall surfaces of the current collector 12 and the air duct 11 can be different, that is, the length extension lines of their outer wall surfaces are arranged at an angle. At this time, a connecting wire will be formed at the connection between the current collector 12 and the air duct 11.

[0055] By making the air passing area of each air supply port 122 smaller than the air passing area of the air inlet 121, when there are multiple air inlets 121, the air passing area of each air supply port 122 is smaller than the air passing area of its corresponding air inlet 121. Therefore, in the air flow flowing from the air outlet 112 to the air supply port 122, part of the air flow will flow out along the inner wall surface of the current collector 12 from the periphery of the air supply port 122, and the other part of the air flow will flow out from the middle of the air supply port 122. The part of the air flow flowing out from the edge of the air supply port 122 is defined as the edge air flow, and the air flow flowing out from the middle of the air supply port 122 is defined as the middle air flow. Then, due to the resistance of the inner wall surface of the current collector 12, the edge air flow has a lower flow velocity compared to the middle air flow. This difference in flow velocity will cause a vortex ring air flow to be generated when the air flow flows out from the air supply port 122.

[0056] The multiple air supply outlets 122 of the air collecting member 12 can be formed by opening on the end face of the air collecting member 12, or each air supply outlet 122 can be formed by multiple small air collecting cylinders. The air inlet 121 can be a large air inlet 121 that communicates with the air outlet 112, or multiple small air inlets 121 corresponding to the multiple air supply outlets 122. It can be understood that when the air flow blown out by the vortex ring generating device 100 is cold air, the blown vortex rings can be clearly visible to the naked eye. By opening multiple air supply outlets 122 on the air collecting member 12, multiple small vortex rings can be blown out from the air collecting member 12 at one time, so as to achieve personalized air supply and make the user experience better.

[0057] In one embodiment, please refer to Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 and Figures 10 to 14 As shown, the vortex ring generating part 2 includes a driving device and a switch door. The switch door is installed on the air duct 11 to block the air flow in the air duct 11 from flowing to the air collecting member 12. The driving device is connected to the switch door to periodically drive the switch door to open or close. Thus, the vortex ring generating part 2 periodically supplies air flow to pass through and blow out through the air collecting member 12.

[0058] In this embodiment, it should be noted that when the switch door is closed, that is, when blocking the air flow in the air duct 11 from flowing to the air collecting member 12, the switch door can be completely closed or partially closed. For example, only 2 / 3, 4 / 5, 5 / 6, 9 / 10, etc. of the channel cross-section of the air duct 11 is closed. The driving device can include a control board and a driving member. The control board controls the driving member to drive the switch door to reciprocate or repeatedly open or close the air duct. The driving device can be arranged in the housing 1, or on the housing 1 or outside the housing 1. In order to prevent the driving device from disturbing the air flow in the air duct, preferably the control member is arranged on the housing 1 or outside the housing 1. It can be understood that a fan can be arranged at the position corresponding to the air outlet 112 or the air inlet 111. The fan can be arranged in the housing 1 or outside the housing 1. The fan drives enough air to blow towards the air outlet 112.

[0059] The opening and closing door can be arranged in the inner cavity of the air duct 11, dividing the inner cavity of the air duct 11 into two parts. Then the opening and closing door can be used to block the air flow towards the air outlet 112; the opening and closing door can also be arranged at the air outlet 112 of the air duct 11. At this time, the opening and closing door can block the air flow from the air outlet 112 to the air collecting member 12. That is, the air flow in the air duct 11 is blocked from flowing to the air collecting member 12, and the air continuously enters the air duct 11. At this time, a certain amount of air flow can be accumulated in the air duct 11 to form a certain pressure. Thus, when the opening and closing door is opened, the air flow in the air duct 11 can form a driving force and blow out from the air inlet 121 to form a vortex ring. In this way, the periodic opening or closing of the opening and closing door enables the air flow to flow out in a pulsed manner, so that the vortex ring can perform long-distance and directional air supply. The opening and closing door can be a door panel structure, a blade structure, a fan structure, etc., as long as it can periodically block the air flow in the air duct 11 from flowing to the air collecting member 12 and form a vortex ring to blow out. In other embodiments, the opening and closing door can also be installed on the air collecting cover to periodically block the air flow from the air outlet 112 to the air supply port 122.

[0060] Specifically, the opening and closing door includes guide vanes. The driving device includes an electromagnet, a gear and a rack that mesh with each other. The electromagnet is used to drive the rack to move up and down in a pulsed manner, and then drive the gear to drive the guide vanes to open and close quickly. Thus, the guide vanes can be periodically opened or closed, and further, the air flow can be periodically driven to blow out through the air collecting member 12 to form a vortex ring. This structure is simple and reliable, and is convenient for operation and control.

[0061] In another embodiment, the vortex ring generating part 3 includes a driving device and a compression member (not shown). The compression member (not shown) is installed on the air duct 11 and / or the air collecting member 12. The driving device is connected to the compression member (not shown) to periodically drive the compression member (not shown) to squeeze the gas on the side close to the air inlet 121 in the air duct 11, and make the gas blow out through the air inlet 121. Thus, the vortex ring generating part 2 periodically drives the air flow to blow out through the air collecting member 12.

[0062] In this embodiment, the compression member (not shown) can be a piston structure, a film structure, etc. When the compression member (not shown) is a piston structure, the piston is sealed with the inner wall surface of the air duct 11 and / or the current collector 12 and can move relative to each other. Then, when the driving device drives the piston to move in the air duct 11 and / or the current collector 12, the gas on the side of the air duct 11 and / or the current collector 12 close to the air inlet 121 can be compressed, and then the gas is pushed to form a vortex ring airflow and blown out from the air inlet 121. In one embodiment, the piston structure includes a push plate and a push rod connected to the push plate, and the push plate is movably connected to the inner wall surface of the air duct 11 and / or the current collector 12. The driving device drives the push rod to drive the push plate to move in the air duct 11 and / or the current collector 12. When the compression member (not shown) is a film structure, the film structure is a flexible material or an elastic material. And the film structure is fixedly connected to the inner wall surface of the air duct 11 and / or the current collector 12, so that by pushing and pulling the film structure, the gas on the side of the air duct 11 and / or the current collector 12 close to the air inlet 121 can be periodically extruded, thereby driving the airflow to form a vortex ring airflow and blown out from the air inlet 121.

[0063] The vortex ring generating part 2 can be installed inside or outside the housing 1 in a detachable manner, or the vortex ring generating part 2 can also be integrally formed with the housing 1. The vortex ring generating part 2 can periodically drive the airflow to blow out through the air duct, that is, it can generate a disturbance in the intake direction of the airflow in the air duct, and the air passing area of the air outlet 112 is smaller than the cross-sectional area of the air duct close to the air outlet 112. Then, when the vortex ring generating part 2 drives the airflow to blow out from the air duct, the airflow blown out from the air supply port 122 forms a vortex ring shape. Under the same air volume, the vortex ring air supply method can achieve directional, fixed-point and long-distance air supply. And the vortex ring exchanges heat with the surrounding ambient air during the transmission process, and the temperature difference between the vortex ring temperature and the surrounding air temperature is not large, ensuring that there is no obvious over-cooling or over-heating feeling when the vortex ring blows on people, and improving the comfort.

[0064] The vortex ring generating device 100 of the present invention opens a plurality of air supply ports 122 on the current collector 12, and the air passing area of each air supply port 122 is smaller than the air passing area of the air inlet 121, so that a plurality of vortex rings can be blown out from the current collector 12, realizing a personalized air supply mode of multiple vortex rings, thereby giving users a brand-new experience.

[0065] In one embodiment, as Figures 1 to 3 and Figures 9 to 14As shown, the collector 12 includes a collector cover 123, and an air inlet 121 is provided on one end surface of the collector cover 123, and the air inlet 121 is connected to the air outlet 112, and a plurality of air supply ports 122 are provided on the other end surface of the collector cover 123. It can be understood that the air inlet 121 is connected to the air outlet 112, which means that the air inlet 121 and the air outlet 112 are arranged to overlap, thus simplifying the structure. The cross-sectional shape of the collector cover 123 can be circular, elliptical, rectangular, etc. In order to reduce wind resistance, the collector cover 123 is roughly cylindrical. The collector 12 is configured as a collector cover 123, which has a simple structure and can increase the length of the air duct, thereby being more conducive to the generation of vortex rings.

[0066] In other embodiments, the current collecting member 12 may also be a current collecting plate, which is mounted on the air outlet 112, and a plurality of air supply ports 122 are provided on the current collecting plate. The current collecting plate may be a plate that covers the air outlet 112, and by providing a plurality of air supply ports 122 that are smaller than the air outlet 112 on the current collecting plate, when the airflow is blown out from the air outlet 112 to the plurality of air supply ports 122, due to the partial blocking effect of the current collecting plate, the airflow blown out from the plurality of air supply ports 122 can be in the shape of a vortex ring. The current collecting plate has a simple structure and is easy to manufacture and process. In addition, the current collecting member 12 may also be formed by enclosing several plates, and by providing an air supply port 122 on one of the plates, the formation of a vortex ring can also be achieved.

[0067] On the basis of the above embodiment in which the current collecting member 12 is a current collecting cover 123, the current collecting cover 123 is further arranged to be gradually reduced from the air inlet 121 to the air outlet 122. In this way, the air flow resistance along the flow collecting cover 123 is small, the air discharge is smoother, and the current collecting cover 123 can be used to collect the air, so that the vortex ring is formed more smoothly.

[0068] In a preferred embodiment, please refer to Figures 1 to 5 ,and Figures 9 to 11 ,, the current collecting part 12 includes a current collecting cover 123 and a plurality of sub-current collecting covers 124 arranged in the current collecting cover 123, each sub-current collecting cover 124 has a sub-air inlet 124a and a sub-air supply port 124b, the wind flow area of ​​each sub-air supply port 124b is smaller than the wind flow area of ​​the sub-air inlet 124a, each sub-air supply port 124b is arranged corresponding to an air supply port 122, and each sub-air inlet 124a is connected to the air inlet 121.

[0069] In this embodiment, the shapes of the sub-inlet 124a and the sub-outlet 124b can be circular, rectangular, elliptical, polygonal, irregular, etc., and no specific limitation is made here. By arranging a plurality of sub-collecting covers 124 in the collecting cover 123, an independent air duct is formed in each sub-collecting cover 124, so that the sub-collecting covers 124 are independent of each other and do not interfere with each other, and thus the generation of the vortex ring is smoother. It can be understood that the length of each sub-collecting cover 124 should be less than or equal to the length of the collecting cover 123. The number of the sub-collecting covers 124 can be designed and selected according to the cross-sectional size of the collecting cover 123. The plurality of sub-collecting covers 124 and the collecting cover 123 can be integrally formed or separately formed. At this time, the plurality of sub-collecting covers 124 can be connected to each other by connecting ribs, snap connections, welding, bonding, etc. The sub-collecting covers 124 can be evenly arranged or unevenly arranged in the collecting cover 123. In one embodiment, the plurality of sub-collecting covers 124 are arranged at intervals along the circumferential direction of the collecting cover 123. In this way, the plurality of small vortex rings blown out are arranged in a circle, the air supply is more uniform, and the shape is more beautiful, giving users a new visual experience.

[0070] Further, as Figure 3 shown, each sub-collecting cover 124 is tapered from the sub-inlet 124a to the sub-outlet 124b. In this way, the flow resistance of the air flow in each sub-collecting cover 124 is small, the air outlet is smoother, and the air collecting function can be achieved, so that the formation of the small vortex ring is smoother. In another embodiment, a baffle is provided on one side of each sub-collecting cover 124 away from the sub-inlet 124a, and a sub-outlet 124b is formed on the baffle. Then, when the air flow blows from the sub-inlet 124a to the sub-outlet 124b, due to the partial blocking effect of the baffle, the air flow blown out from the plurality of sub-outlets 124b can be in a vortex shape.

[0071] In one embodiment, the sub-inlets 124a of two adjacent sub-collecting covers 124 are connected to each other. The two adjacent sub-collecting covers 124 can be connected to each other by bonding or welding, or the outer wall surfaces at the inlets 121 of the plurality of sub-collecting covers 124 can be connected by arranging a connecting plate 125. In this way, the plurality of sub-collecting covers 124 are integrated into one body, the structural strength is improved, and the installation and disassembly of the sub-collecting covers 124 are facilitated. In other embodiments, the outer wall surfaces of two adjacent sub-collecting covers 124 are connected to each other. Similarly, the plurality of sub-collecting covers 124 can be integrated into one body to improve the structural strength.

[0072] On the basis of the above embodiments, further, please refer to Figure 5, the sub-inlet 124a of each subset flow hood 124 is arranged in a rectangular or regular polygon shape. It can be understood that there will be a gap between two adjacent subset flow hoods 124, resulting in a large air resistance and generating a large amount of noise. By setting the sub-inlet 124a of each subset flow hood 124 in a rectangular or regular polygon shape, a structure with small gaps or no gaps can be formed at the inlet 121 of multiple subset flow hoods 124, thereby reducing the air resistance at the inlet 121 of the subset flow hood 124, increasing the air volume, and effectively reducing noise. The rectangle can be a square, a rectangle, a rhombus, etc., and the regular polygon can be an equilateral triangle, a square, a regular pentagon, a regular hexagon, etc. Of course, the subset flow hood 124 can also be of other shapes, as long as the sub-inlets 124a of multiple subset flow hoods 124 can be spliced into a shape with substantially no gaps or small gaps. It can be understood that only the cross-sectional shape of the sub-inlet 124a of the subset flow hood 124 can be set in a rectangular or regular polygon shape, or the overall cross-sectional shape of the subset flow hood 124 can be set in a rectangular or regular polygon shape.

[0073] In one embodiment, please refer to Figure 3 and Figure 4 , the shapes and / or sizes of at least two sub-outlet air vents 124b are set to be different. In this way, vortex rings of different sizes and / or shapes can be blown out from the manifold 12, thereby realizing personalized air supply and giving users a brand-new experience. At this time, the shapes of the sub-inlet 124a and the sub-outlet air vent 124b can be circular, rectangular, oval, regular polygon, irregular shape, etc.

[0074] In another embodiment, as shown in Figure 3 and Figure 4 , in the air supply direction from the inlet 121 to the outlet 122, at least two sub-outlet air vents 124b are arranged in a front-to-back arrangement. In this way, when the manifold 12 blows out multiple vortex rings, the vortex rings blown out by multiple sub-outlet air vents 124b at the same time are not in the same plane and are arranged in a front-to-back manner, with a more three-dimensional sense of hierarchy, realizing a brand-new vortex ring air supply mode, thereby making the user experience better.

[0075] In a preferred embodiment, please refer to Figures 6 to 8 , and Figures 12 to 14 , the manifold 12 includes a connecting plate 125 and a plurality of sub-guide cylinders 126 provided on the same side of the connecting plate 125. The connecting plate 125 is installed at the outlet 112 of the air duct 11. One end of each sub-guide cylinder 126 is provided with an outlet air vent 122, and an inlet 121 is provided at the position of each sub-guide cylinder 126 corresponding to the connecting plate 125. The inlet 121 penetrates through the connecting plate 125, and the vortex ring generating part 2 is arranged on the side of the connecting plate 125 away from the outlet air vent 122.

[0076] In this embodiment, by arranging a plurality of sub-flow guide cylinders 126 on the connecting plate 125, the plurality of sub-flow guide cylinders 126 are integrated into one, thereby improving the structural strength and facilitating the installation and removal of the collector 12. At the same time, an independent air duct is formed in each sub-flow guide cylinder 126, so that the sub-flow guide cylinders 126 are independent of each other and do not interfere with each other, thereby making the generation of multiple vortex rings smoother. It can be understood that the connecting plate 125 can connect the peripheral wall surfaces of the plurality of sub-flow guide cylinders 126, or can connect the end surfaces of the plurality of sub-flow guide cylinders 126. When the connecting plate 125 connects the peripheral wall surfaces of the plurality of sub-flow guide cylinders 126, the air inlet 121 is arranged through the connecting plate 125, so that the airflow of the air outlet 112 can flow smoothly into the sub-flow guide cylinder 126. When the connecting plate 125 is connected to the end surface of the sub-flow guide cylinder 126, the overall structure is more compact and the installation space is small. At this time, the air inlet 121 penetrating the connecting plate 125 is connected to the air outlet 112.

[0077] The plurality of sub-flow guides 126 can be arranged evenly or unevenly on the connecting plate 125. In one embodiment, the plurality of sub-flow guides 126 are arranged in a circumference or in a matrix. In this way, the plurality of small vortex rings blown out are arranged in a circle or in a matrix, making the shape more beautiful and giving the user a new sensory experience. In addition, the air supply is made more uniform while the position and size of the air outlet 122 remain unchanged.

[0078] In one embodiment, if Figure 7 and Figure 8 As shown, each sub-flow guide tube 126 includes a straight section 126a and a tapered section 126b, the air inlet 121 is opened at one end of the straight section 126a away from the tapered section 126b, the air outlet 122 is opened at one end of the tapered section 126b away from the straight section 126a, and the tapered section 126b is arranged to be tapered from the air inlet 121 to the air outlet 122. In this way, the air supply space of the sub-flow guide tube 126 can be increased, which is more conducive to the formation of the vortex ring. And the airflow resistance along the way in the sub-flow guide tube 126 is small, the air outlet is smoother, and it can also play a role in collecting flow, so that the formation of the vortex ring is smoother.

[0079] In one embodiment, the shapes and / or sizes of the air outlets 122 of at least two sub-air guide cylinders 126 are set differently. In this way, vortex rings of different sizes and / or shapes can be blown out from the multiple sub-air guide cylinders 126, thereby realizing personalized air supply and giving users a brand new experience.

[0080] In another embodiment, in the air supply direction from the air inlet 121 to the air supply outlet 122, the air supply outlets 122 of at least two sub-guide cylinders 126 are arranged in a front-back arrangement. In this way, when the flow collector 12 blows out multiple vortex rings, the vortex rings blown out by multiple sub-air supply outlets 124b at the same time are not in the same plane and are arranged in a front-back manner, with a more three-dimensional sense of hierarchy, realizing a brand-new vortex ring air supply mode, thereby making the customer experience better.

[0081] The present invention also proposes an air conditioner indoor unit, as Figures 9 to 14 shown. 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 embodiments. Since this air conditioner indoor unit adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. The air conditioner indoor unit can be a floor-standing air conditioner indoor unit, a mobile air conditioner, a wall-mounted air conditioner indoor unit, a window unit, etc. The air conditioner indoor unit can have one or more vortex ring generating devices 100.

[0082] Furthermore, the air conditioner indoor unit includes a housing 200. The housing 200 has a main air inlet 210, a main air outlet 220, and a heat exchange air duct 230 connecting the main air inlet 210 and the main air outlet 220. The air inlet 111 of the vortex ring generating device 100 is connected to the heat exchange air duct 230.

[0083] In this way, after the air flow heat-exchanged by the air conditioner indoor unit passes through the vortex ring generating device 100, long-distance, fixed-point, and directional air supply of cold air or hot air can be realized. Moreover, the vortex ring generating device 100 does not need to be additionally provided with a heat exchanger, thereby simplifying the structure of the vortex ring generating device 100 and saving costs. The vortex ring generating device 100 can be installed inside or outside the housing 200 of the air conditioner indoor unit in a detachable manner, or can be integrally formed with the housing 200 of the air conditioner indoor unit. In other embodiments, the vortex ring generating device 100 can have an independent air duct. At this time, the air inlet 111 of the vortex ring generating device 100 can be an indoor air inlet, an outdoor air inlet, etc.

[0084] It can be understood that when the vortex ring generating device 100 is installed inside the housing 200, the 11 air ducts can be formed by the housing 200. Then, a large vortex ring air outlet can be provided on the housing 200 corresponding to the multiple air supply outlets 122 of the vortex ring generating device 100, or a plurality of small vortex ring air outlets can be provided, so that each vortex ring air outlet corresponds to an air supply outlet 122.

[0085] The present invention also provides an air conditioner, which includes an indoor unit and an outdoor unit of the air conditioner connected by a refrigerant pipe. Among them, the indoor unit of the air conditioner includes a vortex ring generating device 100, and the specific structure of the vortex ring generating device 100 refers to the above-mentioned embodiments. Since the indoor unit of the air conditioner adopts all the technical solutions of the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one.
