Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and particularly to an indoor unit of an air conditioner and an air conditioner. Background Art

[0002] The existing indoor unit of an air conditioner blows the air flow after heat exchange through a conventional air outlet of the air conditioner. Its air outlet mode is conventional air outlet, and the air flow coming out of the conventional air outlet is fixed. Its radiation range is short and narrow, and it is impossible to achieve large-range and long-distance air supply. Thus, the room temperature distribution is not uniform. For example, during cooling, the temperature is low near the air outlet of the air conditioner, while the temperature is high far away from the air outlet of the air conditioner. If the temperature in the distance is to reach the set temperature, the overall room temperature needs to be reduced to meet the requirement, or the air outlet direction is adjusted through a moving mechanism such as a wind deflector or louvers. Although the traditional air outlet auxiliary moving structures such as wind deflectors and louvers can change the overall air flow direction at the air outlet of the air conditioner to a certain extent, they are still far from achieving the functions of directional and fixed-point air supply.

[0037] The realization of the object, functional features and advantages of the present invention will be further described with reference to the embodiments and the accompanying drawings. Detailed implementation manners

[0038] 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 attached drawings). If the specific posture changes, the directional indications will also change accordingly.

[0039] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include at least one of the features. 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 the solution where both A and B are satisfied simultaneously.

[0040] The present invention provides an indoor unit of an air conditioner, which can be an indoor unit of an air conditioner, a mobile air conditioner, a wall - mounted air conditioner indoor unit, a window air conditioner, etc.

[0041] In the embodiments of the present invention, as Figures 1 to 6As shown in the figure, the indoor air conditioner includes a housing 1, a vortex ring generating device, and a fan assembly 4. The housing 1 has a first air inlet 11, a first air outlet 12, a second air outlet 13, and a heat exchange air duct 14 that connects the first air inlet 11 and the first air outlet 12. The second air outlet 13 is spaced apart from the first air outlet 12. The vortex ring generating device is installed in the housing 1. The vortex ring generating device has an air supply port 221, and the vortex ring generating device is used to periodically blow out vortex ring airflows from the air supply port 221. The air supply port 221 communicates with the interior of the room through the second air outlet 13. The fan assembly 4 is installed in the housing 1, and the fan assembly 4 is used to drive the air flow to the second air outlet 13 and / or drive the air flow to flow from the first air inlet 11 to the first air outlet 12.

[0042] In this embodiment, the housing 1 can be an integral structure or can be formed by splicing several plates. The shapes of the first air inlet 11, the first air outlet 12, the second air outlet 13, and the air supply port 221 can be circular, oval, rectangular, polygonal, irregular, etc., or can be multiple micro holes, and their sizes and shapes are not specifically limited herein. The heat exchange air duct 14 means that the air flow entering from the first air inlet 11 can exchange heat in this channel and then be blown out from the first air outlet 12. The cross-sectional shape of the heat exchange air duct 14 can be circular, oval, arc-shaped, etc., and its extending shape can be a straight tube type or a bent type, etc. The heat exchange air duct 14 can be directly formed by enclosing the housing 1 or can be formed by enclosing the inner wall of the air duct in the housing 1.

[0043] Figure 6 A two-dimensional simulation diagram of the formation of a vortex ring at the air supply port 221 of the vortex ring generating device is given. Here, the simulation is only a two-dimensional simulation of a radius cross-section of one air supply port 221. In other words, the two-dimensional simulation of the radius cross-section obtains a single vortex, the two-dimensional simulation of the diameter cross-section obtains a pair of vortices, and the three-dimensional simulation obtains a vortex ring.

[0044] The vortex ring generating device can be installed inside the housing 1, outside the housing 1, or embedded on the housing 1. The vortex ring air flow refers to the fact that due to a certain stamping effect, the central air flow in the stamped area has a higher flow velocity relative to the air flow in the surrounding area. Then the pressure in the stamped area is lower than the pressure in the surrounding area, and the air flow in the surrounding area is supplemented to the stamped area due to the pressure difference, thus forming a rotatable rotating air flow. Compared with other air flows, the vortex ring air flow can blow farther, and the radius of the vortex ring air flow gradually increases. Therefore, the vortex ring air flow has a long air supply distance, a large radiation range, and can achieve directional and fixed-point air supply. The vortex ring air flow blown out by the vortex ring generating device can be the air flow in the heat exchange air duct 14. At this time, the air inlet end of the vortex ring generating device is connected to the air outlet end of the heat exchange air duct 14. Then the blown vortex ring air flow is the air flow after heat exchange, making the heat exchange air blow farther and have a wider radiation range, thereby enabling the indoor temperature to be quickly exchanged. The vortex ring air flow blown out by the vortex ring generating device can also be the indoor air flow. At this time, the air inlet end of the vortex ring generating device is connected to the indoor. Then, because the vortex ring air flow blows farther and has a wider radiation range, the indoor temperature distribution can be made more uniform, thereby enhancing the user experience.

[0045] When the vortex ring generating device works, the air conditioner indoor unit is in the vortex ring air supply mode, and the vortex ring generating device periodically and stably outputs vortex ring air flow from the air outlet 221. 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 transmission, and the temperature difference between the vortex ring temperature and the surrounding air temperature is not large, ensuring that there is no obvious overcooling or overheating feeling when the vortex ring blows on people, thus enhancing comfort. When the vortex ring generating part 3 does not work, the air conditioner indoor unit is in the conventional air supply mode, and the heat-exchanged conventional air is sent out from the first air outlet 12. The conventional air supply mode and the vortex ring air supply mode can be selectively turned on, or both modes can be turned on simultaneously. At this time, the air conditioner indoor unit can simultaneously achieve vortex ring air supply and conventional air supply.

[0046] By making the air outlet 221 communicate with the indoor through the second air outlet 13, the second air outlet 13 is configured as the vortex ring air outlet 221. The first air outlet 12 is configured as the conventional air outlet 221. In this way, the vortex ring air supply mode and the conventional air supply mode of the air conditioner indoor unit have separate air outlets, so the structure of the conventional air supply of the air conditioner indoor unit does not need to be greatly adjusted, and only a corresponding structure under the vortex ring air supply mode needs to be added. There is no need to greatly change the manufacturing mold, resulting in small structural changes to the product on the original conventional air conditioner, and thus low production and manufacturing costs. At the same time, users can choose to turn on the vortex ring air supply mode and the conventional air supply mode simultaneously, and there are more combined air supply modes, providing a better user experience.

[0047] The blower assembly 4 may include one blower or two blowers. When the blower assembly 4 has one blower, the air supply duct of the vortex ring generating device is in communication with the heat exchange air duct 14 at this time, and this blower drives the air flow to flow towards the first air outlet 12 and the second air outlet 13 simultaneously. Then, for the vortex ring air supply mode and the conventional air supply mode of the air conditioner indoor unit, it is not necessary to use two blower assemblies 4. The entire air conditioner indoor unit can use one blower assembly 4 to drive a sufficient amount of air flow, thereby simplifying the overall structure of the unit and reducing the cost. The blower assembly 4 can be an axial flow blower, a centrifugal blower, a cross-flow blower, or a mixed flow blower. When the blower assembly 4 is a blower of different types, the opening positions of the first air inlet 11, the first air outlet 12, and the second air outlet 13 can be adjusted accordingly, so that the entire air conditioner indoor unit can smoothly discharge air from the first air outlet 12 and the second air outlet 13.

[0048] The following lists several embodiments in which the blower assembly 4 includes one blower. At this time, the air duct of the vortex ring generating device is connected to the heat exchange air duct 14. In one embodiment, the blower assembly 4 is an axial flow blower, and the axial flow blower is located between the first air outlet 12 and the second air outlet 13, or is arranged near the first air inlet 11. At this time, the axial flow blower can drive the air flow to flow in from the first air inlet 11 and towards the first air outlet 12 and the second air outlet 13. In order to ensure sufficient air volume, the axial flow blower can be a contra-rotating blower or a multi-stage blower. In another embodiment, the blower assembly 4 is a centrifugal blower, and the centrifugal blower is located at the lower end of the housing 1. Then the centrifugal blower can drive a sufficient amount of air flow to blow towards the first air outlet 12 and the second air outlet 13. The centrifugal blower can include a single-direction centrifugal impeller or can also include a two-direction centrifugal impeller to increase the air volume. In one embodiment, the centrifugal impeller is a cross-flow impeller, and the cross-flow impeller extends from the first air outlet 12 to the second air outlet 13. In this way, using one cross-flow impeller can ensure that a sufficient amount of air volume blows towards the first air outlet 12 and the second air outlet 13 simultaneously. In other embodiments, the blower assembly 4 can also be a mixed flow impeller.

[0049] The air conditioner indoor unit of the present invention can achieve directional, fixed-point, and long-distance air supply by providing the spaced first air outlet 12 and the second air outlet 13 on the housing 1 and enabling the vortex ring generating device to periodically blow out vortex ring air flow from the air supply port 221. And since the housing 1 has the first air outlet 12 and the second air outlet 13, the first air outlet 12 is used to blow out the conventional air after heat exchange, and the second air outlet 13 is used to blow out the vortex ring air flow, then the air conditioner indoor unit has multiple air supply modes, thereby meeting different needs of users and enhancing the user experience.

[0050] In one embodiment, as Figures 3 to 5As shown, the vortex ring generating device includes a vortex ring air supply part 2 installed on the housing 1. The vortex ring air supply part 2 includes an air duct 21 and a flow collector 22. The air duct 21 is provided with a second air inlet 212 and a third air outlet 211. The flow collector 22 is installed at the third air outlet 211. An air supply port 221 is provided on the flow collector 22. The air passing area of the air supply port 221 is smaller than the air passing area of the third air outlet 211.

[0051] In this embodiment, the vortex ring air supply part 2 includes an air duct 21 and a flow collector 22, which can increase the air supply space of the vortex ring air supply part 2 and is more conducive to the formation of vortex rings. The vortex ring air supply part 2 can be installed on the outer wall surface of the housing 1, can also be installed inside the housing 1, or can be embedded on the housing 1. The vortex ring air supply part 2 and the housing 1 can be integrally formed or separately formed. The air supply port 221 can be connected to the second air outlet 13, or the flow collector 22 can extend out of the second air outlet 13, that is, in the air outlet direction, the second air outlet 13 and the air supply port 221 are arranged front and back, or in the air outlet direction, the air supply port 221 and the second air outlet 13 are arranged front and back. The flow collector 22 and the air duct 21 can be integrally formed or separately formed. It can be understood that when the flow collector 22 and the air duct 21 are separately formed, the flow collector 22 and the air duct 21 are hermetically connected. When the flow collector 22 and the air duct 21 are integrally formed, a virtual demarcation line is defined with the connection between the air duct 21 and the flow collector 22 as the boundary. One side of this demarcation line is the air duct 21, and the other side is the flow collector 22, and a third air outlet 211 of the air duct 21 is formed at the demarcation line. Undoubtedly, the air passing area of this third air outlet 211 is larger than the air passing area of the air supply port 221 of the flow collector 22. The extension directions of the outer wall surfaces of the flow collector 22 and the air duct 21 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 2 has a complete shape without a connecting wire. The extension directions of the outer wall surfaces of the flow collector 22 and the air duct 21 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 flow collector 22 and the air duct 21.

[0052] By making the air passing area of the air supply port 221 smaller than the air passing area of the third air outlet 211, in the air flow from the third air outlet 211 to the air supply port 221, part of the air flow will flow along the inner wall surface of the vortex ring air supply part 2 and then flow out from the periphery of the air supply port 221, and the other part of the air flow will flow out from the middle of the air supply port 221. The part of the air flow flowing out from the edge of the air supply port 221 is defined as the edge air flow, and the air flow flowing out from the middle of the air supply port 221 is positioned as the middle air flow. Then, the edge air flow is affected by the resistance of the inner wall surface of the vortex ring air supply part 2. Compared with the middle air flow, its flow rate is lower. This difference in flow rate will cause vortex ring air flow when the air flow flows out from the air supply port 221.

[0053] In combination with the above embodiment having the current collector 22, further, please refer again to Figures 3 to 5 , the current collector 22 is a current collecting cover, and the current collecting cover is tapered from the third air outlet 211 to the air supply port 221. The cross-sectional shape of the current collecting cover can be circular, elliptical, rectangular, etc. In order to reduce the wind resistance, the current collecting cover is generally in a cylindrical shape. By making the current collecting cover tapered from the third air outlet 211 to the air supply port 221, the current collecting cover can collect the air sent out from the third air outlet 211, and make the generation and blowing of the vortex ring smoother.

[0054] In another embodiment, the current collector 22 is a current collecting plate, the current collecting plate is installed at the third air outlet 211, and the air supply port 221 is opened on the current collecting plate. The current collecting plate can be a plate covering the air outlet, and by opening the air supply port 221 smaller than the third air outlet 211 on the current collecting plate, when the air flow blows from the third air outlet 211 to the air supply port 221, due to the partial blocking effect of the current collecting plate, the air flow blown out from the air supply port 221 can be in a vortex ring shape. And the structure of the current collecting plate is simple and easy to manufacture and process. In other embodiments, the current collector 22 can also be formed by enclosing several plates, and by setting the air supply port 221 on one of the plates, the formation of the vortex ring can also be achieved.

[0055] Further, as Figures 2 to 5 shown, the vortex ring generating device further includes a vortex ring generating part 3, and the vortex ring generating part 3 periodically opens the air duct 21 and / or the current collector 22 to allow the air flow to blow out through the air supply port 221.

[0056] In this embodiment, the vortex ring generating part 3 can be installed in the housing 1, or can be installed on the vortex ring air supply part 2. The vortex ring generating part 3 can be installed in the housing 1 or on the vortex ring air supply part 2 in a detachable manner, or can be integrally formed with the housing 1 or the vortex ring air supply part 2. The vortex ring generating part 3 can be a switch door structure, such as a louver structure, a door panel structure, a fan structure, etc. By periodically opening or closing the switch door structure, the air with a certain pressure accumulated on one side of the switch door 32 can be quickly released from the third air outlet 211, flow to the air supply port 221 and then form a vortex ring and blow out.

[0057] Specifically, please refer again to Figures 2 to 5 , the vortex ring generating part includes a driving device 31 and a switch door 32, the switch door 32 is installed on the vortex ring air supply part 2 to block the air flow in the housing 1 from flowing to the air supply port 221, and the driving device 31 is connected to the switch door 32 to periodically drive the switch door 32 to open or close.

[0058] In this embodiment, it should be noted that when the switch door 32 is closed, that is, when the vortex ring air supply part 2 is closed, it can be completely closed or partially closed. For example, it can be 2 / 3, 4 / 5, 5 / 6, 9 / 10, etc. of the cross-sectional area of the channel of the vortex ring air supply part 2. The vortex ring air supply part 2 can be connected to the heat exchange air duct 14, and then the heat exchange fan 42 in the heat exchange air duct 14 can continuously blow air flow towards the vortex ring air supply part 2. The vortex ring air supply part 2 can also not be connected to the heat exchange air duct 14, and then a vortex ring fan 41 can be set to drive sufficient indoor air flow towards the vortex ring air supply part 2. When the vortex ring generating part 3 works, since the vortex ring air supply part 2 is continuously admitting air, a certain volume of air will accumulate in the vortex ring air supply part 2. When the vortex ring generating part 3 is opened, due to the pressure difference, a driving force will be formed to drive the air flow towards the air outlet 221, and the air passing area of the air outlet 221 is smaller than that of the third air outlet 211, so that a vortex ring air flow can be blown out from the air outlet 221.

[0059] The switch door 32 can be arranged in the air duct 21 and / or the flow collector 22. The switch door 32 can be of a louver structure, a door panel structure, a fan structure, etc. The driving device 31 can include a control board and a driving member. The driving member can be a hydraulic device, a pneumatic device or a motor driving device 31, etc. The driving device 31 can drive the switch door 32 to rotate, expand and contract, etc. to realize driving the switch door 32 to open and close periodically. The control board controls the driving member to drive the switch door 32 to repeatedly open or close the vortex ring air supply part 2. The driving device 31 can be arranged on the air duct 21 or on the flow collector 22. With the structure of the driving device 31 plus the switch door 32, the structure is simple and stable, and is convenient to control, thus being more conducive to the smooth generation of the vortex ring air flow.

[0060] In one embodiment, the switch door 32 includes a plurality of blades, and the vortex ring generating part 3 further includes a transmission member. The transmission member is in transmission connection with the plurality of blades, and the driving device 31 is connected to the transmission member to drive the transmission member to drive the plurality of blades to open or close.

[0061] In this embodiment, the blade structure makes the opening and closing mode of the switch door 32 simpler, more reliable, and easy to implement. In one embodiment, the driving device 31 is an electromagnet, and the transmission member includes a gear connected to a blade shaft, a rack connected to the electromagnet, and a transmission rod connected to multiple blade shafts. The electromagnet pulse drives the rack to drive the gear to rotate, so as to drive multiple blades to open or close. The electromagnet is given a pulse signal to drive the rack to do reciprocating motion, thereby driving the gear to rotate, so as to drive multiple blades to open and close quickly within a certain angle. In another embodiment, the driving device 31 is a motor, and the transmission member includes a large gear connected to the motor shaft, a small gear meshing with the large gear and fixedly connected to a blade shaft, and a transmission rod connected to multiple blade shafts. The motor drives the large gear to drive the small gear to rotate, so as to drive a blade to rotate around its shaft, thereby linking multiple blades to flip.

[0062] In another embodiment, the vortex ring generating device also includes a vortex ring generating part 3, which includes a driving device 31 and a compression element (not shown), and the compression element (not shown) is installed on the vortex ring air supply part 2. The driving device 31 is connected to the compression element (not shown) to periodically drive the compression element (not shown) to squeeze the gas in the vortex ring air supply part 2 close to the air supply port 221, and blow the gas out through the air supply port 221.

[0063] 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 vortex ring air supply portion 2 and can move relative to it. Then, when the driving device 31 drives the piston to move within the vortex ring air supply portion 2, the gas on the side of the vortex ring air supply portion 2 close to the air outlet 221 can be compressed, and then the gas is pushed to form a vortex ring air flow and blow out from the air outlet 221. The piston can be located within the air duct 21 and / or the flow collector 22. 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 vortex ring air duct 23. The driving device 31 drives the push rod to drive the push plate to move within the air duct 21 and / or the flow collector 22. When the compression member (not shown) is a film structure, the film structure is made of a flexible material or an elastic material. And the film structure is fixedly connected to the inner wall surface of the air duct 21 and / or the flow collector 22, so that by pushing and pulling the film structure, the gas on the side of the vortex ring air duct 23 close to the air outlet 221 can be periodically squeezed, thereby driving the air flow to form a vortex ring air flow and blow out from the air outlet 221. The driving device 31 can include a driving member and a transmission member. The driving member can be a motor driving device 31, a hydraulic driving device 31, a pneumatic driving device 31, an electromagnet driving device 31, etc. The transmission member can be a lead screw transmission, a worm and worm gear transmission, a gear and rack transmission, a connecting rod transmission, etc., as long as it can enable the driving member to drive the transmission member to move so as to drive the compression member (not shown) to squeeze the volume on the side of the air duct 21 and / or the flow collector 22 close to the air outlet 221, and specific limitations are not made here.

[0064] In a preferred embodiment, as Figures 3 to 5 shown, the housing 1 further has a vortex ring air supply channel 15 communicating with the second air inlet 212. The vortex ring generating portion 3 is installed in the vortex ring air supply channel 15. The fan assembly 4 includes a vortex ring fan 41 and a heat exchange fan 42. The vortex ring fan 41 is installed in the vortex ring air supply channel 15 to drive the air flow towards the second air outlet 13, and the heat exchange fan 42 is installed in the heat exchange air duct 14 to drive the air flow from the first air inlet 11 to the first air outlet 12.

[0065] In this embodiment, the vortex ring air supply channel 15 and the heat exchange air duct 14 can be separately and independently arranged, or can be arranged to communicate with each other. A partition can be provided within the housing 1 to separate the vortex ring air supply channel 15 from the heat exchange air duct 14. The vortex ring fan 41 and the heat exchange fan 42 can be axial fans, mixed-flow fans, cross-flow fans, centrifugal fans, etc. By making the fan assembly 4 include the vortex ring fan 41 and the heat exchange fan 42, the vortex ring fan 41 provides the air flow driving force for the vortex ring air supply channel 15, and the heat exchange fan 42 provides the air flow driving force for the heat exchange air duct 14, so that there is sufficient air volume at the first air outlet 12 and the second air outlet 13. That is, sufficient air volume can be ensured in both the vortex ring air supply mode and the conventional air supply mode, thereby improving the energy efficiency ratio.

[0066] In one embodiment, please refer to Figure 5 , the outer casing 1 further has a third air inlet 16, the vortex ring air supply channel 15 communicates the third air inlet 16 with the second air inlet 212, the vortex ring blower 41 is an axial flow blower, and the axis of the axial flow blower is arranged towards the second air inlet 212.

[0067] In this embodiment, the axial flow blower can be a single impeller blower or a pair of impeller blowers. The third air inlet 16 can communicate with the heat exchange air duct 14. It can also be separately opened and arranged facing the second air inlet 212. In this way, the third air inlet 16 can be arranged facing the axial flow blower, so that the air resistance is small and the air intake volume is larger. Only indoor air can flow into the third air inlet 16, so the air sent out from the air supply port 221 is fresh indoor air. Of course, a vortex ring heat exchanger can also be arranged in the vortex ring air supply channel 15, so that the vortex ring air flow after heat exchange is sent out from the air supply port 221, thereby increasing the heat exchange amount of the entire air conditioner indoor unit and making the user experience better. By arranging the axial flow blower facing the second air inlet 212, the air blown out from the axial flow blower has small air resistance along the way when flowing towards the second air inlet 212, and the air outlet is more uniform and the noise is smaller at the same time. And the axial flow blower is installed in the outer casing 1 facing the second air inlet 212, making the overall structure more compact.

[0068] In another embodiment, please refer to Figure 3 and Figure 4 , the vortex ring air supply channel 15 is communicated with the heat exchange air duct 14, the heat exchange air duct 14 extends in the up and down direction, and the vortex ring blower 41 includes an axial flow impeller, and the axis of the axial flow impeller extends in the up and down direction.

[0069] In this embodiment, by communicating the vortex ring air supply channel 15 with the heat exchange air duct 14, the air flow entering the vortex ring air supply channel 15 is the air flow after heat exchange. In this way, a heat exchanger does not need to be separately arranged in the vortex ring air supply channel 15, reducing the energy consumption of the air conditioner indoor unit, thereby increasing the heat exchange energy efficiency ratio, making the structure of the entire air conditioner indoor unit simpler, the overall occupied space smaller, and the production and manufacturing costs lower. By making the axis of the axial flow impeller extend in the up and down direction, the axis direction of the axial flow impeller is consistent with the extension direction of the heat exchange air duct 14, so that a sufficient amount of air flow after heat exchange can be driven through the axial flow impeller, thereby ensuring the smooth generation of the vortex ring air flow.

[0070] In a preferred embodiment, as Figure 1 shown, the first air outlet 12 is located below the second air outlet 13. In this way, when the air conditioner indoor unit is in the vortex ring air supply mode, the vortex ring air flow blows out from the upper end of the outer casing 1. Then, since the vortex ring air flow has a certain distance from the ground, after the vortex ring air flow is sent out from the second air outlet 13, there is enough space for air supply and it is not easily blocked by the ground. Therefore, the vortex ring air supply can send the air farther and is more likely to achieve directional, fixed-point and long-distance air supply.

[0071] In one embodiment, the first air outlet 12 is arranged in a long strip shape, and the second air outlet 13 is arranged in a circular shape. By arranging the first air outlet 12 in a long strip shape, the first air outlet 12 can be opened large enough, so as to ensure that the air conditioner can blow out a large amount of air flow in the conventional air supply mode, and then ensure that the indoor space can be quickly heat-exchanged. Since the air blown out by the second air outlet 13 is a vortex ring air flow. When the second air outlet 13 is arranged in a square or polygonal shape, the stress at the corner transition of the second air outlet 13 is more concentrated, and the air resistance received by the periphery of the second air outlet 13 is uneven, resulting in a relatively large noise. By arranging the second air outlet 13 in a circular shape, the air resistance received is small and uniform, so the noise during the air supply of the second air outlet 13 is smaller.

[0072] In combination with the above embodiment having the heat exchange fan 42, further, please refer to Figure 3 , the heat exchange fan 42 is a cross-flow fan. The heat exchange fan 42 uses a cross-flow fan, and the blown air is more concentrated and can be sent farther under low-noise conditions. At the same time, the air flow blown out from the first air outlet 12 is more uniformly distributed along the axis, so the blown air is more comfortable and the user experience is better.

[0073] In one embodiment, the fan assembly 4 further includes a dual-axis motor. The vortex ring fan 41 includes an axial flow impeller, and the heat exchange fan 42 includes a cross-flow impeller. One rotating shaft of the dual-axis motor is connected to the axial flow impeller, and the other rotating shaft of the dual-axis motor is connected to the cross-flow impeller. By enabling the dual-axis motor to drive the cross-flow impeller and the axial flow impeller simultaneously, the cross-flow impeller and the axial flow impeller do not need to be driven by a separate motor, which simplifies the structure of the indoor unit of the air conditioner, improves the energy consumption ratio, and reduces the cost. In other embodiments, the heat exchange fan 42 and the axial flow fan are each provided with a separate motor for driving.

[0074] In one embodiment, as Figures 2 to 5 shown, the vortex ring generating part 3 includes a driving device 31 and a switch door 32. The switch door 32 is installed in the vortex ring air supply part 2 to block the air flow in the housing 1 from flowing to the air outlet 221. The driving device 31 is connected to the switch door 32 to periodically drive the switch door 32 to open or close.

[0075] In this embodiment, the opening and closing door 32 can be a louver structure, a door panel structure, a fan structure, etc. The driving device 31 can include a control board and a driving member. The driving member can be a gear driving device 31, a hydraulic device, a pneumatic device, or a motor driving device 31, etc. The driving device 31 can drive the opening and closing door 32 to rotate, extend and retract, etc., so as to drive the opening and closing door 32 to be periodically opened and closed. The control board controls the driving member to drive the opening and closing door 32 to repeatedly open or close the third air outlet 211. The driving device 31 can be arranged on the vortex ring air supply part 2 or on the housing 1. In order to prevent the driving device 31 from obstructing the air flow in the vortex ring air supply part 2, preferably, the control member is arranged on the housing 1. Through the structure of the driving device 31 plus the opening and closing door 32, the structure is simple and stable, and is convenient to control, thus being more conducive to the smooth generation of the vortex ring air flow.

[0076] The present invention also provides an air conditioner, which includes an outdoor unit and an indoor unit of the air conditioner. The outdoor unit and the indoor unit of the air conditioner are connected by a refrigerant pipe. The specific structure of the indoor unit of the air conditioner refers to the above embodiment. Since this air conditioner 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.
