Further, as shown in fig. 2 to 4, the vortex ring air duct 23 of the vortex ring generating device 2 is communicated with the heat exchange air duct 14. By communicating the vortex ring air duct 23 with the heat exchange air duct 14, the air flow entering the vortex ring air duct 23 is the air flow after heat exchange, and the vortex ring blown out is the air flow after heat exchange. Therefore, a heat exchanger does not need to be arranged in the vortex ring air supply channel, the energy consumption of the air conditioner indoor unit is reduced, the heat exchange energy efficiency ratio is improved, and the whole air conditioner indoor unit is simpler in structure, small in occupied space of the whole machine and lower in production and manufacturing cost.

The air outlet 300 may be connected to the vortex ring air outlet 111, or the flow collecting member 213 may be extended out of the vortex ring air outlet 111, that is, the vortex ring air outlet 111 and the air outlet 300 are arranged in front and back directions in the air outlet direction, or the air outlet 300 and the vortex ring air outlet 111 are arranged in front and back directions in the air outlet direction. The collecting member 213 and the air duct 212 may be integrally formed with the casing 1 or may be separately formed. The collecting member 213 and the air duct 212 may be integrally formed or may be separately formed. It can be understood that when the collecting member 213 is formed separately from the air duct 212, the collecting member 213 is hermetically connected to the air duct 212. When the collecting member 213 and the air duct 212 are integrally formed, a virtual boundary is defined by a boundary at a junction between the air duct 212 and the collecting member 213, one side of the boundary is the air duct 212, the other side is the collecting member 213, and the air outlet 200 of the air duct 212 is formed at the boundary. Clearly, the air outlet 200 has a larger air passing area than the air inlet 300 of the collecting member 213. The extension directions of the outer wall surfaces of the flow collecting piece 213 and the air duct 212 may be the same, that is, the length extension lines of the outer wall surfaces of the flow collecting piece 213 and the air duct 212 are a straight line, and at this time, the flow collecting piece 213 and the air duct 212 are in a shape of a complete patch cord-free. The extending directions of the collecting member 213 and the outer wall surface of the air duct 212 may be different, that is, the length extending lines of the outer wall surfaces of the collecting member 213 and the air duct 212 form an included angle, and at this time, a junction line is formed at the junction of the collecting member 213 and the air duct 212.

Since the air flow passing through outlet 300 is smaller than the air flow passing through outlet 200, some of the air flow flowing from outlet 200 to outlet 300 flows along the inner wall surface of flow collecting member 213 and then flows out from the periphery of outlet 300, and the other air flow flows out from the middle of outlet 300. The partial flow flowing out from the edge of the blower port 300 is defined as edge flow, and the flow flowing out from the center of the blower port 300 is positioned as center flow. Then, the edge flow receives resistance from the inner wall surface of the collecting member 213. The flow velocity is lower compared to the middle stream. This difference in flow rates will cause a vortex ring flow (as shown) to occur as the air flows out of the supply port 300.

In the above embodiment with the collecting member 213, the collecting member 213 is a collecting cover, and the collecting cover is gradually reduced from the air outlet 200 to the air blowing opening 300. The cross-sectional shape of the manifold can be circular, oval, rectangular, etc. In order to reduce wind resistance, the collecting cover is substantially cylindrical. By making the flow collecting cover gradually decrease from the air outlet 200 to the air supply opening 300, the flow collecting cover can collect the flow of the air discharged from the air outlet 200, and the generation and blowing of the vortex ring can be smoother.

In another embodiment, the collecting member 213 is a collecting plate, and the collecting plate is installed at the air outlet 200 and is provided with an air inlet 300. The collecting plate may be a plate covering the outlet 200, and the air flow from the air supply port 300 may be made into a vortex shape by a partial blocking effect of the collecting plate when the air flow is blown out from the outlet 200 to the air supply port 300 by forming the air supply port 300 smaller than the outlet 200 in the collecting plate. And the collector plate has simple structure and is easy to manufacture and process. In other embodiments, the collecting member 213 may be formed by several plates, and the formation of the vortex ring may be also achieved by providing the air blowing port 300 on one of the plates.

In an embodiment, referring to fig. 4 to 6, the vortex ring generating device 2 further includes a vortex ring generating portion 22, the vortex ring generating portion 22 is disposed corresponding to the air inlet 100, and the vortex ring generating portion 22 periodically drives the air flow to be blown out through the air outlet 300, or the vortex ring generating portion 22 periodically blocks the air flow from flowing to the air inlet 100.

Specifically, the vortex ring generating portion 22 includes a driving device 223 and an opening and closing door 224, the opening and closing door 224 is installed at the air inlet 100 to block the air flow of the air inlet 100 from flowing to the air outlet 300, and the driving device 223 is connected to the opening and closing door 224 to drive the opening and closing door 224 to open or close. So that the vortex ring generating portion 22 periodically blocks the airflow to the intake opening 100.

In this embodiment, it should be noted that when the switch door 224 is closed, that is, when the outlet 200 is closed, the outlet 200 may be completely closed, or may be partially closed, for example, 2/3, 4/5, 5/6, 9/10 and the like that close the outlet 200. The air outlet 200 may be communicated with the heat exchange air duct 14, so that the heat exchange fan 3 can continuously blow the air flow to the air outlet 200. The air outlet 200 may not be communicated with the heat exchange air duct 14, and a vortex ring fan may be provided to drive sufficient indoor airflow to flow to the air outlet 200. When the vortex ring generating portion 22 operates, a certain volume of air is accumulated at the air outlet 200 because the air outlet 200 continuously supplies air. When the vortex ring generating part 22 opens the air outlet 200, a driving force is generated to drive the airflow to flow to the air outlet 300 due to the pressure difference, and the air passing area of the air outlet 300 is smaller than that of the air outlet 200, so that the air outlet 300 can blow the vortex ring airflow.

The opening and closing door 224 may be a louver structure, a door panel structure, a fan structure, etc. The driving device 223 may include a control panel and a driving member, the driving member may be a hydraulic device, a pneumatic device, or a motor driving device 223, and the driving device 223 may drive the switch door 224 to rotate, extend, and retract, so as to drive the switch door 224 to open and close periodically. The control board controls the driving member to drive the opening and closing door 224 to repeatedly open or close the outlet 200. The driving device 223 may be disposed on the wind pipe 212 or on the collecting member 213. The structure of the opening and closing door 224 is added through the driving device 223, so that the structure is simple and stable, and the control is convenient, thereby being more beneficial to the smooth generation of vortex ring airflow.

In one embodiment, the driving device 223 is an electromagnet, and the transmission member includes a gear connected to a blade rotating shaft, a rack connected to the electromagnet, and a transmission rod connected to the blade rotating shafts in a transmission manner, and the rack is driven by the pulse of the electromagnet to drive the gear to rotate so as to drive the blades to open or close. Pulse signals are given through the electromagnet to drive the rack to do reciprocating motion, and then the gear is driven to rotate so as to drive the blades to be rapidly opened and closed within a certain angle. In another embodiment, the driving device 223 is a motor, the driving member includes a gear connected to the motor shaft, a pinion engaged with the gear and fixedly connected to a blade rotating shaft, and a transmission rod drivingly connected to the blade rotating shafts, the motor drives the gear to rotate the pinion to drive a blade to rotate around its rotating shaft, so as to link the blades to turn.

Specifically, the scroll ring generator 22 includes a drive device 223 and a compressor (not shown), the compressor is attached to the scroll ring duct 23, the drive device 223 is connected to the compressor (not shown), and the compressor (not shown) is periodically driven to compress the gas in the scroll ring blowing unit 21 on the side close to the blowing port 300 and blow the gas out through the blowing port 300. So that the vortex ring generating portion 22 periodically drives the air flow to be blown out through the air blowing port 300.

In the present embodiment, the compressing member (not shown) may be a piston structure, a thin film structure, or the like. When the compression element (not shown) is a piston structure, the piston is sealed with the inner wall surface of the scroll passage 23 and can move relatively. When the driving device 223 drives the piston to move in the scroll passage 23, the gas on the side of the scroll passage 23 close to the air blowing opening 300 can be compressed, and the gas can be pushed to form a scroll airflow from the air blowing opening 300 and be blown out. The piston may be located within the air duct 212 and/or the manifold 213. In one embodiment, the piston structure includes a pushing plate and a pushing rod connected to the pushing plate, and the pushing plate is movably connected to the inner wall surface of the vortex ring air duct 23. The driving device 223 drives the pushing rod to drive the pushing plate to move in the scroll air channel 23. 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 with the inner wall surface of the vortex ring air duct 23, the gas on one side of the vortex ring air duct 23 close to the air supply opening 300 can be periodically extruded through pushing and pulling the film structure, so that the air flow is driven to form vortex ring air flow from the air supply opening 300 and blown out.

In a preferred embodiment, referring to fig. 4 and 5, the scroll ring air-supplying portion 21 further includes a mounting plate 214, the air duct 212 is mounted on the mounting plate 214, the air inlet 100 is disposed at a connection position of the mounting plate 214 and the air duct 212, the mounting portion 211 is disposed at a side of the mounting plate 214 close to the scroll ring air outlet 111, and a side of the mounting plate 214 away from the scroll ring air outlet 111 is connected to the scroll ring generating portion 22.

In the present embodiment, by having the air duct 212 mounted on the mounting plate 214, the mounting plate 214 can mount the air duct 212 and the current collecting member 213 on the vortex ring generating portion 22 and the panel 11 at the same time. Specifically, the end face of the current collecting member 213 is disposed flush with the panel 11 or protruding out of the panel 11. The connection stability of the mounting plate 214 is ensured, and the manual switching of the position of the vortex ring air supply part 21 is more convenient and faster. The face of mounting panel 214 and the face of the air-out side of vortex ring emergence portion 22 can be the laminating setting, reduces the clearance between the two, so, reduces the air leakage, guarantees that the air current that vortex ring emergence portion 22 promoted can most blow to vortex ring air supply portion 21, and then makes the vortex ring air current bigger, blow farther. The connection between the air duct 212 and the vortex ring generating part 22 via the mounting plate 214 is simpler and more reliable. And because the overfire area of the vortex ring air outlet 111 is larger than that of the air supply outlet 300, the mounting plate 214 can also play a role in blocking wind, so that the non-vortex ring airflow is reduced from being blown out of the vortex ring air outlet 111, and the influence of the non-vortex ring airflow on the vortex ring airflow is reduced.

Specifically, as shown in fig. 4, the area of the mounting plate 214 is greater than or equal to the air passing area of the vortex ring air outlet 111. Thus, when the vortex ring air supply part 21 is in the adjusting position, the mounting plate 214 can mostly or completely shield the vortex ring air outlet 111 except the vortex ring air supply part 21, so that the vortex ring air outlet 111 only blows out vortex ring air flow, and the vortex ring air flow volume blown out by the vortex ring air outlet 111 is larger, and the air supply is more remote and more accurate.

In an embodiment, referring to fig. 1 to 5, the vortex ring generating portion 22 is fixedly connected to the housing 1, the vortex ring generating portion 22 has a mounting surface 221 facing the vortex ring outlet 111, a telescopic structure 222 is disposed on the mounting surface 221, one side of the mounting plate 214 is mounted on the panel 11, the other side of the mounting plate 214 presses against the telescopic structure 222, and the mounting plate 214 can move along a direction perpendicular to the mounting surface 221, so that the mounting portion 211 can be switched among the plurality of mounting locations 112.

In the present embodiment, the mounting surface 221 may be formed by a mounting panel of the vortex ring generating portion 22. The vortex ring generating part 22 can be fixedly connected in the shell by means of screws, clamping, bonding and the like. At this time, the position of the vortex ring blowing unit 21 is merely switched without moving the vortex ring generating unit 22, thereby changing the blowing direction of the blowing port 300. The telescopic structure 222 may be an elastic member, a sleeve member, a rack and pinion structure member, or the like, that is, the telescopic structure 222 may be an elastic restoring member, for example, a spring 500, and only needs to be capable of moving in a direction perpendicular to the mounting surface 221. By providing the telescopic structure 222 on the mounting surface 221, when the telescopic structure 222 is in the extended position, one side of the mounting plate 214 abuts against the telescopic structure 222, and the other side is hung on the panel 11. In this way, the scroll ring blowing section 21 can be stably connected between the face plate 11 and the scroll ring generating section 22. When the telescopic structure 222 is in the retracted position, a certain space is left between the panel 11 and the vortex ring generating part 22, so that the mounting part 211 of the vortex ring air supply part 21 can be separated from a single mounting position 112 and switched among the mounting positions 112, and the position of the vortex ring air supply part 21 can be adjusted, so that the air supply position of the air supply opening 300 can be adjusted. It will be appreciated that this arrangement is more advantageous to facilitate manual switching of the position of the scroll ring blower 21.

In a preferred embodiment, referring to fig. 5 again, the retractable structure 222 includes a position-limiting pillar 400 fixed on the mounting surface 221, a spring 500 sleeved on the position-limiting pillar 400, a top block 600 and a sleeve 700, the sleeve 700 is sleeved on the periphery of the spring 500 and the top block 600, one end of the top block 600 abuts against the spring 500, and the other end of the top block 600 extends out of the sleeve 700.

In this embodiment, the telescopic structure 222 is an elastic member composed of a spring 500, a limiting post 400, a top block 600, and a sleeve 700. So that the telescopic structure 222 can be automatically returned by the elastic restoring force of the spring 500. Thereby switching the telescopic position of the telescopic structure 222 without using a human hand or the driving device 223. The structure is simple and reliable, and the cost is low. The number of the telescopic structures 222 may be one, two, three, four, five, six, etc., and the number may be determined according to the areas of the mounting surface 221 and the mounting plate 214, which is not particularly limited herein. When the spring 500 is in a natural state, the top block 600 abuts against the mounting plate 214 so that the scroll blowing part 21 is always in close contact with the panel 11, and when the mounting position 112 needs to be switched, the blowing position of the blowing port 300 can be switched by pressing and moving the scroll generating part 22. The manual switching is more convenient and faster.

In the above embodiment where the vortex ring generating portion 22 is fixedly connected to the housing 1, further, referring to fig. 2, 4 and 5, a vortex ring air duct 23 is defined in the vortex ring generating device 2, the vortex ring generating portion 22 is disposed at an air outlet end of the vortex ring air duct 23 and is disposed corresponding to the vortex ring air outlet 111, an air outlet area of the vortex ring air duct 23 is larger than an air passing area of the air supply opening 300, or an air outlet area of the vortex ring air duct 23 is larger than or equal to an air passing area of the vortex ring air outlet 111.

In the present embodiment, it can be understood that the air outlet area of the vortex ring air duct 23 refers to the air passing area or the driving air flow area of the vortex ring generating portion 22. Since the vortex ring generating portion 22 is fixed to the housing 1, the air outlet area of the vortex ring air duct 23 is larger than the air passing area of the air supply opening 300, or the air outlet area of the vortex ring air duct 23 is larger than the air passing area of the vortex ring air outlet 111. When the vortex ring blowing part 21 moves relative to the face plate 11, that is, relative to the vortex ring generating part 22, it is always ensured that the blowing port 300 is provided corresponding to the vortex ring generating part 22, that is, smooth generation of vortex ring airflow is ensured.

In another embodiment, the mounting plate 214 is fixedly attached to the vortex ring generating portion 22. In this way, when the blowing position of the blowing port 300 is switched, the entire vortex ring generator 2 can be moved. Furthermore, the air outlet cross section of the vortex ring generating part 22 does not need to be arranged greatly, and the whole structure is simplified. At this time, in order to make the installation of the vortex ring generating portion 22 more stable, the vortex ring generating portion 22 may be movably installed on the housing 1.
