For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0084] Reference is made below Figures 1-24 The air conditioner indoor unit 1000 according to the embodiments of the present application is described.

[0085] The air conditioner indoor unit 1000 according to the embodiments of the present application is described. Figure 1 and Figure 7As shown, it comprises: a casing A, a first air outlet A21, a second air outlet A22 and an air outlet mesh cover L, the casing A comprises a main body A6 and a front panel A8, and the casing A is formed with an air inlet A1. The second air outlet A22 is arranged around the first air outlet A21, and the front panel A8 is provided with a front air outlet A2, and the outer edge of the front air outlet A2 corresponds to the outer edge of the second air outlet A22; the air outlet mesh cover L is arranged at the front end of the first air outlet A21 and the second air outlet A22, and is connected at the front air outlet A2.

[0086] The air outlet mesh cover L is arranged at the front end of the first air outlet A21 and the second air outlet A22, and is connected at the front air outlet A2. It can be understood that the air outlet of the existing air conditioner is arranged in an open manner, which causes the internal structure of the air conditioner to be exposed to the outside, and the appearance is relatively simple and not beautiful. In the present scheme, the air outlet mesh cover L is arranged at the front end of the first air outlet A21 and the second air outlet A22, which can protect the structure inside the air conditioner, is more secure, and can make the flow of air more uniform, thereby enhancing the air outlet effect and improving the user experience. In addition, the shape of the air outlet mesh cover L can be changed to make it more diversified and more beautiful in shape.

[0087] It should be noted that the air after heat exchange in the air conditioner can be divided into two parts, one part of the air reaches the first air outlet A21 to be sent out, and the flow rate is slowed down after encountering the air outlet mesh cover L and the air is uniformly sent out; the other part of the air is sent out after passing through the second air outlet A22 and the air outlet mesh cover L, thereby increasing the air outlet range of the air conditioner and improving the adjustment effect on indoor air.

[0088] According to the air conditioner indoor unit 1000 of the embodiment of the present application, the air outlet mesh cover L is arranged at the front end of the first air outlet A21 and the second air outlet A22, so that the structure of the air conditioner indoor unit 1000 has diversity, and the air outlet effect can be further enhanced, thereby improving the user experience.

[0089] The air conditioner indoor unit 1000 according to the embodiment of the present application will be described in detail below with reference to Figures 1-24 .

[0090] In some embodiments, as shown in Figure 1 and Figure 3 , the front end of the main body A6 has an open port A7, and the front panel A8 is arranged at the front end of the main body A6 and covers at least part of the open port A7. In this way, the air after heat exchange in the air conditioner can also be sent out through the part of the open port A7 which is not covered. Specifically, in addition to the front panel A8 having the front air outlet A2 on the entire casing, the part of the open port A7 on the main body A6 which is not covered also serves as another air outlet, so that the casing has multiple outlets for air outlet. The cold air or hot air after heat exchange in the air conditioner can be sent out through multiple outlets, and the air outlet range is larger and the effect is better.

[0091] Specifically, as shown in Figure 2 and Figure 3 , the cabinet A is further provided with a third air outlet A3, which is located above the front air outlet A2 and blows air forward. It should be noted that Figure 2 and Figure 3 The arrow indicates the direction of the air flow. That is, the third air outlet A3 and the front air outlet A2 jointly expand the air outlet range in front of the air conditioner, thereby further improving the front air outlet capacity of the air conditioner. When the air conditioner blows air outward, it can not only blow air outward from the front air outlet A2 of the front panel A8, but also blow air upward from the third air outlet A3 at the top of the air conditioner, thereby further improving the air outlet effect. It should be noted that the front of the air conditioner in the present application refers to the side of the air conditioner facing the user. The third air outlet A3 mentioned above can be defined by the unclosed opening A7 part of the main body A6.

[0092] In some embodiments, as shown in Figure 3 and Figure 4 , the first air outlet A21 is in communication with the air inlet A1, and in the first air duct A4 formed by the communication, a first fan D is arranged; the second air outlet A22 is in communication with the air inlet A1, and in the second air duct A5 formed by the communication, a second fan E is arranged; the first fan D and the second fan E are controlled independently. In this way, the first fan D is used to drive air to flow from the air inlet A1 to the front air outlet A2, that is, the air sent from the air inlet A1 can be driven by the first fan D and discharged from the front air outlet A2, and the second fan E is used to drive air to flow from the air inlet A1 to the front air outlet A2 or the unclosed opening A7 part mentioned above.

[0093] In some embodiments, as shown in Figure 5 , the upper edge part of the front panel A8 and the upper edge part of the unclosed opening A7 have a predetermined gap A71. That is, the predetermined gap A71 defines another air outlet in addition to the front air outlet A2 at the front end of the air conditioner indoor unit 1000, and the other air outlet is located at the top of the air conditioner. The third air outlet A3 and the front air outlet A2 located below it blow air together, and the air conditioner can blow air outward from the front air outlet A2 of the front panel A8 when blowing air outward, and can blow air upward from the third air outlet A3 of the air conditioner, thereby expanding the air outlet range of the air conditioner, thereby further improving the front air outlet capacity of the air conditioner, and thereby enhancing the air outlet effect. It should be noted that the front of the air conditioner in the present application refers to the side of the air conditioner facing the user.

[0094] Specifically, the lower edge of the front panel A8 can be fitted with the lower edge of the opening A7, the left edge of the front panel A8 can be fitted with the left edge of the opening A7, and the right edge of the front panel A8 can be fitted with the right edge of the opening A7. This ensures that the aforementioned edges overlap, guaranteeing no gaps between them, and ensuring that the air after heat exchange within the air conditioner can only be delivered from the front air outlet A2 and the third air outlet A3.

[0095] Furthermore, such as Figure 5 As shown, in the main view of casing A, the predetermined gap A71 can range from 40mm to 150mm. It is understandable that if the predetermined gap A71 is too small, it will hinder the rapid delivery of air after heat exchange within the air conditioner, potentially causing air to accumulate inside the casing, increasing internal pressure and resulting in poor heat dissipation. Conversely, if the predetermined gap A71 is too large, the air after heat exchange will be instantly delivered from another air outlet, leading to uneven airflow and hindering air circulation within the room. Therefore, setting the predetermined gap A71 to a range of 40mm to 150mm ensures that within this range, the airflow through the predetermined gap A71 is more effective.

[0096] In a specific embodiment, the size of the predetermined gap A71 can be 40mm. At this time, the size difference between the top air outlet formed by the predetermined gap A71 and the air outlet on the front panel A8 is large. Under this state, the air after heat exchange by the air conditioner is mainly sent out from the front air outlet A2, and is supplemented by being sent out from the top air outlet formed by the predetermined gap A71, thereby improving the air conditioning air outlet effect.

[0097] In a specific embodiment, the size of the predetermined gap A71 can be 66mm. This can be understood as ensuring not only better air delivery from the air conditioner but also better air circulation within the room, resulting in optimal airflow from the predetermined gap A71.

[0098] In a specific embodiment, the size of the predetermined gap A71 can also be 150mm. This can be understood as the smallest size difference between the top air outlet formed by the predetermined gap A71 and the front air outlet A2 on the front panel A8. In this state, the air after heat exchange by the air conditioner mainly comes from the two air outlets. The two have basically the same function and work together to regulate the air conditioner's outward airflow.

[0099] In some embodiments, such as Figures 1-5As shown, the height of the front panel A8 can range from 1300mm to 1800mm. In this way, the height of the front air outlet A2 is suitable for the height of the human body, and the air sent out by the front air outlet A2 can be directly blown to the area where the human body is located. In combination with the structure of the third air outlet A3 described above, the height of the third air outlet A3 is higher than the area where the human body is located. At this time, the air sent out by the third air outlet A3 is blown above the human body, and then the airflow naturally sinks to the area where the human body is located. At this time, the human body will not feel the wind or feel a weak wind, thereby improving the comfort of the user.

[0100] The ratio between the height of the front panel A8 and the height of the air outlet mesh cover L ranges from 2 to 5, and the ratio between the area of the front panel A8 and the area of the air outlet mesh cover L ranges from 3 to 6. The following is an optional embodiment:

[0101] Alternatively, in some specific embodiments, the height of the front panel A820 can be 1300mm. At this time, the height of the front panel A820 is the smallest, and the height of the relative air outlet 21 is smaller. When the air conditioner blows air, it is relatively concentrated at a lower height in the room.

[0102] In specific embodiments, the height of the front panel A820 can also be 1800mm. At this time, the height of the front panel A820 is the largest, and the height of the relative air outlet 21 is larger. When the air conditioner blows air, it is relatively concentrated at a higher height in the room.

[0103] In specific embodiments, the ratio between the height of the front panel A8 and the height of the air outlet mesh cover L can be 3.75, and the ratio between the area of the front panel A8 and the area of the air outlet mesh cover L can be 4.5. In this way, it is more conducive to production and manufacturing.

[0104] In specific embodiments, the height of the front panel A8 is 1582mm, and the height of the main body A6 is 1879mm. At this time, the ratio of the heights of the two is suitable, and the appearance is more beautiful.

[0105] In specific embodiments, the distance between the bottom of the air outlet mesh cover L and the bottom of the main body A6 is 1234mm. Similarly, the position of the air outlet mesh cover L can be used to determine the position of the front air outlet A2. In this way, the height position of the air outlet mesh cover L and the front air outlet A2 is the most suitable, which is conducive to the air conditioner to blow air outward. In addition, when the air outlet mesh cover L is at this height position, the air conditioner can avoid direct blowing to children when blowing air outward, and avoid children from catching a cold or other diseases due to direct blowing in a cold air state.

[0106] In some embodiments, as Figure 5As shown, the size of the air outlet mesh cover L in the left-right direction can range from 350mm to 450mm. The air outlet mesh cover L is connected to the front air outlet A2. If the size of the air outlet mesh cover L is too small, it will hinder the air outlet capacity of the front air outlet A2. In view of the actual size of the air conditioner, the size of the air outlet mesh cover L is more appropriate in this size range. Similarly, the air outlet mesh cover L in this size is easy to manufacture and is conducive to production.

[0107] In specific embodiments, the size of the air outlet mesh cover L in the left-right direction can be 350mm. At this time, the size of the air outlet mesh cover L is the smallest, and the air outlet capacity of the front air outlet A2 is limited to some extent to achieve a stable air outlet effect of the front air outlet A2.

[0108] In specific embodiments, the size of the air outlet mesh cover L in the left-right direction can be 382mm. Thus, the size of the air outlet mesh cover L is appropriate, and the air supply effect is good.

[0109] In specific embodiments, the size of the air outlet mesh cover L in the left-right direction can also be 450mm. At this time, the size of the air outlet mesh cover L is the largest, and the flow rate of the air blown out by the front air outlet A2 is the largest, which helps to further expand the air outlet range of the air conditioner.

[0110] More specifically, as shown, Figure 5 when the size of the air outlet mesh cover L in the left-right direction is 382mm, the size of the air outlet mesh cover L in the up-down direction is 392mm at this time. Thus, the area of the air outlet mesh cover L in this size can completely cover the front air outlet A2.

[0111] In some optional embodiments, as shown, Figure 6 the air outlet mesh cover L is provided with a plurality of uniformly arranged equilateral triangular mesh holes L1, and the length of each mesh hole L1 ranges from 1mm to 20mm. Thus, the mesh hole L1 is shaped as an equilateral triangle, which can play a better decorative role and make the whole more beautiful. Secondly, the mesh hole L1 that is too small is not conducive to air supply, and the mesh hole L1 that is too large cannot play a certain air resistance effect. Therefore, the length of the mesh hole L1 is set to range from 1mm to 20mm, which is conducive to air supply and also plays a certain air resistance effect to improve the air outlet effect.

[0112] In specific embodiments, the length of the equilateral triangular mesh hole L1 on the air outlet mesh cover L can be 1mm. That is, at this time, the size of the mesh hole L1 on the air outlet mesh cover L is the smallest and dense, and it is not easy to observe the internal structure of the air conditioner, which is more decorative in appearance and more beautiful.

[0113] In specific embodiments, the length of the equilateral triangular mesh hole L1 on the air outlet mesh cover L can also be 20mm. That is, at this time, the size of the mesh hole L1 on the air outlet mesh cover L is the largest and loose, which is conducive to air outlet of the air conditioner.

[0114] In specific embodiments, the side length of the plurality of mesh holes L1 can be 13.5 mm. This can facilitate production and reduce costs.

[0115] In other embodiments, the shape of the mesh holes L1 is not limited to the shape of an equilateral triangle, and can be set to other shapes, for example, the mesh holes L1 can also be rhombic, rectangular, circular, or elliptical (not shown in the figure). When the mesh holes L1 are rhombic, the side length of the rhombus can be 13.5 mm, thereby ensuring that the mesh holes L1 have good ventilation effects.

[0116] Of course, in other embodiments of the present application, the shape of the mesh holes L1 can be various, and can be a combination of multiple patterns. For example, the air outlet mesh cover L can be composed of multiple concentric circular regions (not shown in the figure), the mesh holes L1 of the innermost concentric circular region are equilateral triangles, the mesh holes L1 of the outer concentric circular region are rhombic, and the mesh holes L1 of the outermost concentric circular region are directional, thereby making the overall appearance more beautiful. For another example, the air outlet mesh cover L can be composed of multiple square ring regions (not shown in the figure), the mesh holes L1 of the innermost square ring region are rhombic, the mesh holes L1 of the outer square ring region are square, and the mesh holes L1 of the outermost square ring region are equilateral triangles, which also improves the aesthetic appearance.

[0117] In some optional embodiments, as shown in Figure 6 The ratio of the sum of the areas of the plurality of mesh holes L1 to the area of the air outlet is in the range of 0.5-0.8. In this way, that is, the air outlet mesh cover L as a whole can have a certain wind resistance effect, and the air in the air conditioner indoor unit 1000 after heat exchange is first acted on the air outlet mesh cover L and diffuses after being hindered and blows out from the mesh holes L1, thereby avoiding the concentrated blowing out of the air after heat exchange, and part of the air conditioner air will directly pass through the mesh holes L1 and blow out after being acted on the air outlet mesh cover L, but the wind feeling of the human body has been reduced to a certain extent, and has more suitable comfort, and the other part of the air will diffuse along the circumference of the air outlet mesh cover L and blow out from the nearest mesh holes L1, so that the mesh holes L1 at the remaining positions on the air outlet mesh cover L are all passed through by the air, and the effect of uniform blowing is achieved, thereby improving the air feeling of the air conditioner.

[0118] In some embodiments, as shown in Figure 1As shown, the front surface of the front panel A8 is arc-shaped, the left edge portion and the right edge portion of the front panel A8 extend backward, and the bending radius of the left edge portion and the right edge portion of the front panel A8 ranges from 30 mm to 80 mm. In this way, the front surface of the front panel A8 is designed to be arc-shaped, so that the front panel A8 has a certain depth in the front-rear direction and can play a certain wrapping role when cooperating with the front end surface of the main body A6, so that the inside of the casing A is more compact, and the combination of the two is better and easier to manufacture. Secondly, the arc-shaped front panel A8 is more excellent in design, avoiding sharp edges of the left edge and the right edge of the casing A, which can reduce the damage to the human body during transportation and is more secure. In addition, the arc-shaped structure design is more aesthetic, the appearance is more beautiful, and the touch of the air conditioner is better.

[0119] In specific embodiments, the bending radius of the left edge portion and the right edge portion of the front panel A8 is 46 mm. It can be understood that this is the optimal value of the bending radius of the left edge portion and the right edge portion of the front panel A8, which is more conducive to the combination of the front panel A8 and the main body A6.

[0120] Of course, in specific examples, the bending radius of the left edge portion and the right edge portion of the front panel A8 can be 30 mm, which is more convenient for manufacturing the front panel A8, can reduce the manufacturing difficulty, and save the manufacturing cost.

[0121] In addition, in other examples, the bending radius of the left edge portion and the right edge portion of the front panel A8 can also be 80 mm, which makes the depth of the combination of the front panel A8 and the main body A6 deeper, that is, the combination of the two is more secure.

[0122] In other embodiments, the size of the front panel A8 in the front-rear direction ranges from 60 mm to 100 mm. Specifically, the size of the front panel A8 in the front-rear direction is 70 mm. It can be understood that 70 mm is the optimal size of the front-rear direction of the front panel A8, and it can also be understood that the depth of the front-rear direction of the front panel A8 is 70 mm, which is conducive to the close wrapping of the front panel A8 on the main body A6 and the combination of the two.

[0123] In other embodiments, the thickness of the middle portion of the main body A6 in the front-rear direction is 118 mm, and the thickness of the upper end portion and the lower end portion of the main body A6 in the front-rear direction is 207 mm. It can be understood that the values at this time are the optimal size of the main body A6 in the front-rear direction, but are not limited thereto. With this size design, the overall casing A is more slim and has a stronger three-dimensional effect, so that the internal structure is more compact and the volume is smaller, which does not occupy too much space and is convenient for placement

[0124] In some embodiments of the present application, as shown in Figure 3 and Figure 4As shown, the air conditioner indoor unit 1000 further comprises a guide ring G with a circular cross section in the front-rear direction, the first air duct A4 is defined in the guide ring G, and the second air duct A5 is defined between the outer wall of the guide ring G and the inner wall of the casing A. It can be understood that part of the air delivered by the air inlet A1 can be guided through the second air outlet A22 to enter the indoor air conditioning air.

[0125] Further, as shown in Figure 4 and Figure 7 As shown, the air conditioner indoor unit 1000 further comprises an air outlet frame F with a rectangular cross section in the front-rear direction, the air outlet frame F is arranged in the casing A, the guide ring G is arranged in the air outlet frame F, and the second air outlet A22 is defined between the outer wall of the guide ring G and the inner wall of the air outlet frame F. In this way, another part of the air delivered by the air inlet A1 can be guided through the guide ring G, and the air can flow in the first air duct A4. In this way, the air of the air inlet A1 can be guided in multiple ways, improving the range of air flow, thereby improving the air supply effect of the air conditioner indoor unit 1000.

[0126] Among them, part of the air entering from the air inlet A1 can be guided through the first air duct A4 to enter the indoor from the first air outlet A21. Another part of the air delivered by the air inlet A1 can be guided through the position between the air outlet frame F and the guide ring G to enter the indoor from the second air outlet A22. In this way, the air of the air inlet A1 can be guided in multiple ways, improving the range of air flow, thereby improving the air supply effect of the guide mechanism J.

[0127] The first fan D and the second fan E are independently controlled, that is, the control of the first fan D and the second fan E is independent of each other and does not affect each other. Specifically, the first fan D and the second fan E can work at the same time or one of them can guide air. The rotational speed of the first fan D and the second fan E can be the same or different, thereby diversifying the air supply mode of the air conditioner indoor unit 1000 and improving the air supply effect.

[0128] Specifically, the first fan D can be an axial fan or a cross-flow fan. The second fan E can be a centrifugal fan or a cross-flow fan, thereby making the structure of the first fan D and the second fan E more diverse and the air supply effect better.

[0129] It should be noted that the first fan D is not limited to the above-mentioned axial fan or cross-flow fan, and the first fan D can also be a centrifugal fan, etc. The second fan E is not limited to the above-mentioned centrifugal fan or cross-flow fan, and the second fan E can also be an axial fan or an inclined flow fan, etc.

[0130] In some embodiments, the air conditioner indoor unit 1000 comprises a guide air assembly J1, which comprises a longitudinal vane 130 and a transverse vane 110. The longitudinal vane 130 is arranged at the first air outlet A21 and is used to guide air in the left-right direction. In this way, air at the second air outlet A22 can be guided by the longitudinal vane 130, so as to send the air into the room.

[0131] The transverse vane 110 is arranged at the front side of the longitudinal vane 130 and is used to guide air in the up-down direction. In this way, the transverse vane 110 can be used to guide the air sent out by the first air outlet A21 and the second air outlet A22 at the same time, expand the range of air flow, reduce the occupied space of the guide air assembly J1, thereby improving the air supply effect of the guide air assembly J1 and improving the user experience.

[0132] In some embodiments, as shown in Figure 3 and Figure 24 , the casing A is provided with a heat exchanger B, which is arranged at the rear side of the main body A6. The rear side of the heat exchanger B is provided with an air inlet mesh cover M, which is fitted on the rear side of the main body A6 and wraps the heat exchanger B in the casing A. Air enters the casing A from the air inlet mesh cover M, exchanges heat through the heat exchanger B, and then flows out from the front air outlet A2 of the front panel A8 and the air outlet mesh cover L. Another part blows upward through the predetermined gap A71. The front air outlet A2 and the predetermined gap A71 improve the air outlet effect of the air conditioner.

[0133] Optionally, as shown in Figure 5 , the top of the open hole A7 is provided with a chamfer A61, which can reduce the sharp change, improve safety, and also have a certain air guiding effect. For example, when the air conditioner indoor unit 1000 blows air outward through the open hole A7, the flow rate at this position is small and the pressure is small when the air passes through the chamfer A61. The air at this position blows outward along the chamfer A61, so that the air passing through the open hole A7 blows outward in a horn shape, thereby expanding the blowing range and avoiding wind concentration. It also has the effect of improving the comfort of blowing air.

[0134] The following refers to Figures 8-14The air guide mechanism J according to an embodiment of the present application is described. As shown in the drawings, the air guide mechanism J comprises: a guide ring G, a first air fan D, a second air outlet A22 and at least one air guide vane 100, the guide ring G is formed with a first air inlet A1 and a first air outlet A21; the first air fan D is arranged in the guide ring G, for driving air to flow out of the first air outlet A21 from the first air inlet A1; the second air outlet A22 is arranged around the first air outlet A21; for guiding the air flowing out of the first air outlet A21, and at the same time guiding the air flowing out of the second air outlet A22. That is, by means of the at least one air guide vane 100, for guiding the air flowing out of the first air outlet A21 and the second air outlet A22 at the same time, the range of air guiding can be expanded, the occupied space of the air guide mechanism J is reduced, thereby improving the air supply effect of the air guide mechanism J, and improving the user experience.

[0135] In some embodiments, as shown in Figure 8 and Figure 9 , the air guide mechanism J of the air conditioner indoor unit 1000 further comprises: an air outlet frame F. The air outlet frame F comprises a back plate F1, and the back plate F1 is provided with a ventilation hole F4. The guide ring G is arranged in the air outlet frame F, and the axis of the guide ring G is perpendicular to the ventilation hole F4. The guide ring G is defined with a first air duct A4 penetrating through the length direction thereof along the axial direction thereof, the first air duct A4 is in communication with the air inlet A1 and the first air outlet A21, and the second air outlet A22 is defined between the air outlet frame F and the guide ring G. It can be understood that part of the air sent by the air inlet A1 can flow forward through the ventilation hole F4, pass through the guiding of the first air duct A4, and enter the indoor from the first air outlet A21. Another part of the air sent by the air inlet A1 can pass through the position between the air outlet frame F and the guide ring G for guiding, and enter the indoor from the second air outlet A22. In this way, the air of the air inlet A1 can be guided in multiple ways, the range of air flow is improved, and the air supply effect of the air guide mechanism J is improved.

[0136] In some embodiments, as shown in Figure 8 , the air guide vane 100 comprises: a plurality of transverse vanes 110. The plurality of transverse vanes 110 are respectively rotatably arranged in the air outlet frame F and located on the front side of the guide ring G. The plurality of transverse vanes 110 are arranged in the up-down direction and spaced apart. At least a part of the plurality of transverse vanes 110 is provided with a groove 1101 for accommodating the guide ring G, and the parts of the transverse vanes 110 located on both sides of the groove 1101 extend rearward to the rear side of the front end of the guide ring G. It can be understood that the groove 1101 can make the parts of the transverse vanes 110 located on both sides of the groove 1101 extend rearward to the rear side of the front end of the guide ring G. In this way, the distance between the transverse vane 110 and the first air fan D is shortened, the air volume of air supply is increased, and the air supply range of the transverse vane 110 can be expanded, thereby improving the air supply effect of the transverse vane 110.

[0137] Specifically, as shown in Figures 8-12 The air guide mechanism J further comprises a connecting rod 120 and a driving device 160. The connecting rod 120 extends in the up-down direction, and each of the transverse vanes 110 is connected to the connecting rod 120. The driving device 160 is connected to the connecting rod 120 or the transverse vanes 110 to drive the transverse vanes 110 to rotate. It can be understood that when the driving device 160 is connected to the connecting rod 120, the driving device 160 can drive the connecting rod 120, so that the transverse vanes 110 connected to the connecting rod 120 rotate together with the connecting rod 120; the driving device 160 can also drive at least one of the transverse vanes N10, so that the connecting rod 120 connected to the transverse vane 110 moves together with the transverse vane 110, and then the other transverse vanes 110 connected to the connecting rod 120 rotate together with the connecting rod 120, and then the rotating transverse vanes 110 can guide the air flow direction of the first air outlet A21 and the second air outlet A22.

[0138] Further, as shown in Figure 9 The air guide mechanism J further comprises a connecting rod 120 and a driving device 160. The connecting rod 120 extends in the up-down direction, and each of the transverse vanes 110 is connected to the connecting rod 120. The driving device 160 is connected to the connecting rod 120 or the transverse vanes 110 to drive the transverse vanes 110 to rotate. It can be understood that when the driving device 160 is connected to the connecting rod 120, the driving device 160 can drive the connecting rod 120, so that the transverse vanes 110 connected to the connecting rod 120 rotate together with the connecting rod 120; the driving device 160 can also drive at least one of the transverse vanes N10, so that the connecting rod 120 connected to the transverse vane 110 moves together with the transverse vane 110, and then the other transverse vanes 110 connected to the connecting rod 120 rotate together with the connecting rod 120, and then the rotating transverse vanes 110 can guide the air flow direction of the first air outlet A21 and the second air outlet A22.

[0139] In some optional embodiments, as shown in Figures 9-11 The connecting rod 120 is provided with a plurality of hooks 1201, and the plurality of transverse vanes 110 are one-to-one correspondingly connected to the plurality of hooks 1201. The transverse vane 110 is provided with a mounting column 1103, and the mounting column 1103 is matched with the hook 1201. That is, through the cooperation of the mounting column 1103 and the hook 1201, the connecting rod 120 is connected to the transverse vane 110, and under the action of the friction between the mounting column 1103 and the hook 1201, the connecting rod 120 and the transverse vane 110 can move together.

[0140] Specifically, as shown in Figure 13As shown, the transverse guide vane 110 is provided with a rearwardly open mounting groove 1102, and a mounting column 1103 is arranged in the mounting groove 1102, wherein the hook 1201 hooks the mounting column 1103 from top to bottom or from bottom to top, and the mounting columns 1103 on each transverse guide vane 110 correspond in the up-down direction. In this way, the hook 1201 can hook the mounting column 1103 from top to bottom or from bottom to top, so that the transverse guide vane 110 is connected with the connecting rod 120. Since the transverse guide vane 110 is mounted on the left side plate F2 and the right side plate F3 of the air outlet frame F, the left side plate F2 and the right side plate F3 can limit the transverse guide vane 110, so that the connecting rod 120 connected with the transverse guide vane 110 can be stably mounted on the transverse guide vane 110.

[0141] Further, as shown, Figure 12 Each hook 1201 includes a transverse extension 1201A and a longitudinal extension 1201B, the transverse extension 1201A and the longitudinal extension 1201B are connected with each other perpendicularly, and the transverse extension 1201A is connected with the connecting rod 120. The transverse extension 1201A is semicircular in cross section. It can be understood that the transverse extension 1201A can provide a matching surface for the mounting column 1103, and after assembly, there is a certain friction between the transverse extension 1201A and the mounting column 1103, so that the mounting column 1103 rotates together on the hook 1201. For example, when the driving device 160 drives at least one of the plurality of transverse guide vanes 110, the friction between the mounting column 1103 on the vane N10 and the arc surface can drive the connecting rod 120 to rotate together, and in turn drive the other vanes N10 on the hook 1201 to rotate relatively. When the driving device 160 directly drives the connecting rod 120, the friction between the mounting column 1103 and the transverse extension 1201A will directly drive the transverse guide vane 110 to rotate with the connecting rod 120, thereby realizing air guiding.

[0142] The mounting column 1103 in the embodiment can pass through the longitudinal extension 1201B to fit the outer surface of the transverse extension 1201A, so that the vane N10 does not need to be assembled on the hook 1201 by extrusion, which can reduce the deformation of the hook 1201 as much as possible, thereby increasing the structural strength of the hook 1201, and improving the assembly efficiency of the vane N10 and the hook 1201.

[0143] Alternatively, as shown, Figure 10As shown, one end of the length of the link 120 is provided with a hook 1201, and the other end of the length of the link 120 is provided with a transverse stopper 1202 perpendicular to the length of the link 120. It can be understood that the hook 1201 provided at one end of the length of the link 120 can be used to mount the transverse vane 110. In this way, when the transverse vane 110 is mounted on the hook 1201, the transverse stopper 1202 provided at the other end of the length of the link 120 can provide a stop position for clamping, thereby facilitating the mounting of the transverse vane 110.

[0144] In some alternative embodiments, as shown in Figure 13 As shown, on the transverse vane 110 provided with the recess 1101, a mounting groove 1102 is formed in the bottom wall of the recess 1101 and recessed forward, and the lowermost transverse vane 110 of the plurality of transverse vanes 110 is arranged below the lowermost end of the guide ring G, and the mounting groove 1102 is formed in the rear end of the transverse vane 110 and recessed forward. It can be understood that the transverse vane 110 provided with the recess 1101 can make part of the transverse vane 110 extend rearward to the rear side of the front end of the guide ring G. In this way, the distance between the transverse vane 110 and the axial flow fan is shortened, thereby increasing the air volume of the air supply, and the air supply range of the air guide blade 100 can be expanded, thereby improving the air supply effect of the air guide blade 100. The lowermost transverse vane 110 arranged below the lowermost end of the guide ring G can be used to guide the air sent by the second air duct A5, and then discharged outside through the second air outlet A22.

[0145] In some alternative embodiments, as shown in Figure 8 and Figure 13 As shown in the front view of the transverse vane 110, the front end of the transverse vane 110 is arc-shaped, the rear end of the transverse vane 110 is linear, and the recess 1101 is formed in the middle part of the rear end of the transverse vane 110, wherein the length of the recess 1101 of the plurality of transverse vanes 110 gradually decreases in the direction from the center of the guide ring G to the upper and lower sides. In this embodiment, the front end of the transverse vane 110 is arc-shaped, and the rear end of the transverse vane 110 is linear. In this way, the space required for the rotation of the transverse vane 110 is reduced, which is conducive to the miniaturization of the air guide mechanism J. The length of the recess 1101 in the middle part of the rear end of the transverse vane 110 gradually decreases in the direction from the middle part to the upper and lower sides in the radial direction of the guide ring G. It can be understood that the transverse dimension of the guide ring G gradually decreases from the center to the upper and lower sides, and part of the transverse vane 110 provided with the recess 1101 is arranged to extend rearward to the rear side of the front end of the guide ring G. In this way, the gradual decrease of the length of the recess 1101 in the direction from the center of the guide ring G to the upper and lower sides is conducive to cooperation with the guide ring G.

[0146] Optionally, the vertical distance between the side wall of the groove 1101 and the outer wall of the guide circle G is in the range of 5mm-20mm. In this way, the side wall of the groove 1101 is kept at a proper distance from the outer wall of the guide circle G, so that the transverse vane N10 does not contact the guide circle G during rotation, ensuring the rigidity of the transverse vane 110.

[0147] Further, the length of the groove 1101 is in the range of 100mm-350mm, and the depth of the groove 1101 is in the range of 20mm-30mm. In this way, the rear end of each transverse vane 110 corresponds in the up-down direction, and the part of the transverse vane 110 extending backward to the rear side of the front end of the guide circle G is at a proper distance, so that the distance of the transverse vane 110 to the first fan D can be shortened without affecting the normal operation of the first fan D, and the air volume of the air supply is increased, and the air supply range of the transverse vane 110 can be expanded.

[0148] In some embodiments, as shown in Figure 8 and Figure 9 The air guide vane 100 further comprises a longitudinal vane 130. The longitudinal vane 130 is arranged in the second air outlet A22. It should be noted that in this way, air can enter from the bottom of the air outlet frame F, or air can enter from the rear of the air outlet frame F. For example, air is guided out of the second air outlet A22, or air is guided out of the third air outlet A3, regardless of how the air flows in the air outlet frame F, the air in the air outlet frame F can pass through the second air outlet A22 and be guided by the longitudinal vane 130 described below.

[0149] The longitudinal vane 130 comprises at least two first air guide vanes 1301 and a plurality of second air guide vanes 1302, and the first air guide vanes 1301 and the second air guide vanes 1302 are linked. That is, when the first air guide vanes 1301 move, the second air guide vanes 1302 also move, and the first air guide vanes 1301 and the second air guide vanes 1302 move and stop at the same time.

[0150] The length of the first air guide vane 1301 is greater than the length of the second air guide vane 1302, the plurality of first air guide vanes 1301 are pivotally arranged on the air outlet frame F, and the plurality of second air guide vanes 1302 are pivotally arranged between the guide circle G and the air outlet frame F. That is, the first air guide vane 1301 is rotatable relative to the air outlet frame F, and the second air guide vane 1302 is rotatable relative to the air outlet frame F and the guide circle G.

[0151] The air guide driving mechanism 150 drives the longitudinal vane 130 to oscillate. The air guide driving mechanism 150 controls the movement or stop of the longitudinal vane 130.

[0152] From the above structure, the first guide vane 1301 is pivotally arranged on the air outlet frame F, and the second guide vane 1302 is pivotally arranged on the air guide ring G and the air outlet frame F, so that the guide vane 100 has stable rotating support points and reliable connection, and the guide vane 100 is not easy to be separated from the air outlet frame F or the air guide ring G during rotation, and has good reliability, and the guide vane 100 can continuously and stably guide air.

[0153] It can be understood that the first guide vane 1301 has a relatively long length, and both ends thereof are connected to the air outlet frame F, while the second guide vane 1302 has a relatively short length and a relatively large number, and is respectively connected to the air guide ring G and the air outlet frame F. Compared with all the first guide vanes 1301 having a relatively long length, the present application sets a plurality of second guide vanes 1302 having a relatively short length, which greatly enhances the rigidity of the guide vane 100 as a whole and reduces the resistance of air outlet. In addition, compared with arranging all the guide vanes 100 on the air outlet frame F, the second guide vane 1302 of the present application is arranged with one end on the air outlet frame F and the other end on the air guide ring G, and the arrangement of the second guide vane 1302 is easy and convenient for connection, and is not easy to deform or fall out after connection. In addition, the longitudinal guide vane 130 of the present application does not need to be arranged on the air outlet side of the entire air outlet frame F, but can be selectively arranged on a local area of the air outlet frame F, and the arrangement of the second guide vane 1302 is more flexible.

[0154] Specifically, as shown in Figure 9 , the plurality of second guide vanes 1302 includes a plurality of first group guide vanes 1302A and a plurality of second group guide vanes 1302B, the first group guide vanes 1302A are arranged above the air guide ring G, and the second group guide vanes 1302B are arranged below the air guide ring G. That is, the upper end of the first group guide vane 1302A located above the air guide ring G is pivotally connected to the air outlet frame F, and the lower end is pivotally connected to the air guide ring G; the upper end of the second group guide vane 1302B located below the air guide ring G is pivotally connected to the air guide ring G, and the lower end is pivotally connected to the air outlet frame F.

[0155] In some optional embodiments, as Figure 9As shown, the longitudinal guide vane 130 further comprises a sweeping wind connecting rod 170, the wind guide driving mechanism 150 drives the sweeping wind connecting rod 170 to reciprocate, and the first wind guide blade 1301 and the second wind guide blade 1302 are respectively slidably connected on the sweeping wind connecting rod 170. The longitudinal guide vane 130 can be in a left and right sweeping state or an up and down sweeping state. When the longitudinal guide vane 130 is in the left and right sweeping state, the sweeping wind connecting rod 170 reciprocates left and right under the action of the wind guide driving mechanism 150; when the longitudinal guide vane 130 is in the up and down sweeping state, the sweeping wind connecting rod 170 reciprocates up and down under the action of the wind guide driving mechanism 150. Here, no specific limitation is made.

[0156] Specifically, as shown in Figure 14 and Figure 15 , the sweeping wind connecting rod 170 comprises: a driving sweeping wind connecting rod 1701 and a driven sweeping wind connecting rod 170, the driving sweeping wind connecting rod 1701 is provided with a sliding groove 1704, one end of the first wind guide blade 1301 is provided with a first guide rod 140 which is in sliding cooperation with the sliding groove 1704, the other end of the first wind guide blade 1301 is connected to the driven sweeping wind connecting rod 170, the end of the second wind guide blade 1302 close to the driving sweeping wind connecting rod 1701 is provided with a second guide rod which is in sliding cooperation with the sliding groove 1704, and the end of the second wind guide blade 1302 close to the driven sweeping wind connecting rod 170 is connected to the driven sweeping wind connecting rod 170. Thus, the first wind guide blade 1301 and the second wind guide blade 1302 can form a linkage movement, and the first wind guide blade 1301 and the second wind guide blade 1302 can keep consistent in the movement state such as the swing angle in addition to moving and stopping together.

[0157] In some optional embodiments, as shown in Figure 9 and Figure 15 , the driving sweeping wind connecting rod 1701 and the driven sweeping wind connecting rod 170 are arranged in parallel, the wind guide driving mechanism 150 drives the driving sweeping wind connecting rod 1701 to reciprocate, and the driving sweeping wind connecting rod 1701 drives the driven sweeping wind connecting rod 170 to reciprocate through the first wind guide blade 1301. That is, when the wind guide driving mechanism 150 drives the driving sweeping wind connecting rod 1701 to reciprocate left and right, the driving sweeping wind connecting rod 1701 simultaneously drives the first wind guide blade 1301 and the first group of wind guide blades 1302A to move, and the first wind guide blade 1301 on the driving sweeping wind connecting rod 1701 transmits the force to the driven sweeping wind connecting rod 170 connected thereto, so that the driven sweeping wind connecting rod 170 follows the movement, and the driven sweeping wind connecting rod 170 further drives the second group of wind guide blades 1302B to move. Therefore, the first wind guide blade 1301 and the second wind guide blade 1302 of the present application have high synchronization, the swing angle control is accurate, the wind guide driving mechanism 150 is simple to arrange, and occupies less arrangement space.

[0158] Specifically, as shown in Figure 9 and Figure 15 , when the active sweeping link 1701 reciprocates, the first guide rod 140 slides from one end of the sliding groove 1704 to the other end, the first guide vane 1301 rotates 90 degrees, the second guide rod slides from one end of the sliding groove 1704 to the other end, and the second guide vane 1302 rotates 90 degrees. At this point, the longitudinal guide vane 130 can be switched to the first motion state and the second motion state respectively after rotating 90 degrees, so that the guide mechanism J has the first motion state and the second motion state, and the guide mechanism J can be converted between the first motion state and the second motion state.

[0159] Optionally, as shown in Figure 9 and Figure 15 , the sliding groove 1704 is formed in a semilunar or arc shape, which is smooth when the first guide rod 140 and the second guide rod slide in the sliding groove 1704, and the sliding groove 1704 is easy to guide.

[0160] In some optional embodiments, as shown in Figure 9 and Figure 15 , the guide driving mechanism 150 includes a sweeping motor 1501 and a transmission gear 1502, the sweeping motor 1501 drives the transmission gear 1502 to rotate, and the active sweeping link 1701 is provided with a transmission tooth 1702 matched with the transmission gear 1502. Thus, when the sweeping motor 1501 rotates, the active sweeping link 1701 can be driven to reciprocate stably through the cooperation of the transmission gear 1502 and the transmission tooth 1702.

[0161] In some optional embodiments, as shown in Figure 9 and Figure 15 , the sweeping link 170 includes two active sweeping links 1701 arranged in parallel, the guide driving mechanism 150 includes two and drives the two active sweeping links 1701 to reciprocate respectively, the two ends of the first guide vane 1301 are slidably connected to the two active sweeping links 1701, and one end of the second guide vane 1302 is slidably connected to one of the active sweeping links 1701. That is, the first guide vane 1301 and the second guide vane 1302 are driven by the active sweeping link 1701 and directly change the motion state. At this time, the driving transmission of the guide driving mechanism 150 should be as synchronized as possible to make the motion state of all the first guide vanes 1301 and all the second guide vanes 1302 consistent.

[0162] In some optional embodiments, as shown in Figure 8 and Figure 9As shown, the second air guide vane 1302 increases in length in the direction away from the axis of the guide ring G. Thus, the second air guide vane 1302 is more adapted to the shape of the space between the guide ring G and the air outlet frame F, making the second air guide vane 1302 easier to arrange and move after arrangement.

[0163] Optionally, as shown in Figure 8 and Figure 9 , the longitudinal guide vane 130 has a first movement state and a second movement state, and the longitudinal guide vane 130 is switchable between the first movement state and the second movement state, wherein in the first movement state, the first air guide vane 1301 and the second air guide vane 1302 are parallel to the plane on which the air outlet side of the guide ring G is located, and the gap between the first air guide vane 1301 and the second air guide vane 1302 is 1-2 mm; that is, the blade surfaces of the first air guide vane 1301 and the second air guide vane 1302 block the air flow between the guide ring G and the air outlet frame F in the air outlet direction, greatly reducing the amount or speed of air flowing out of the second air outlet A22. At this time, the first air guide vane 1301 and the second air guide vane 1302 form a side wall, changing the air flow direction of the second air outlet A22 in the air outlet frame F. When the gap between the first air guide vane 1301 and the second air guide vane 1302 is greater than 2 mm, the two cannot form a side wall in the first movement state, and when the gap between the first air guide vane 1301 and the second air guide vane 1302 is less than 1 mm, the two are likely to overlap or interfere with and collide with other connecting parts in the first movement state.

[0164] In the second movement state, the first air guide vane 1301 and the second air guide vane 1302 are parallel to the extension direction of the guide ring G, the blade surfaces of the first air guide vane 1301 and the second air guide vane 1302 are opposite, and the distance between the blade surfaces of the first air guide vane 1301 and the second air guide vane 1302 is 4-6 mm. That is, the blade surfaces of the first air guide vane 1301 and the second air guide vane 1302 are parallel to the air outlet direction of the guide ring G, allowing the air in the second air outlet A22 to pass smoothly between the guide ring G and the air outlet frame F. If there is air outlet in the guide ring G2, the entire longitudinal guide vane 130 will be subjected to a relatively large amount of air flow along the air outlet side of the guide ring G at this time. In the second movement state, when the distance between the blade surfaces of the first air guide vane 1301 and the second air guide vane 1302 is less than 4 mm, the air guide vanes 10031 arranged will be too dense, making it inconvenient to link and install; when the distance between the blade surfaces of the first air guide vane 1301 and the second air guide vane 1302 is greater than 6 mm, the air guide vanes 100 arranged are too sparse, and the flexibility is poor when adjusting the air outlet.

[0165] Optionally, as shown in Figure 8 and Figure 9As shown, the longitudinal guide vane 130 has a first motion state and a second motion state, and the longitudinal guide vane 130 can switch between the first motion state and the second motion state. In the first motion state, the projected area of ​​the first guide vane 1301 and the second guide vane 1302 in the air outlet frame F accounts for 80% to 90% of the difference between the cross-section of the air outlet frame F and the cross-section of the guide ring G. In the second motion state, the projected area of ​​the first guide vane 1301 and the second guide vane 1302 in the air outlet frame F accounts for 5% to 10% of the difference between the cross-section of the air outlet frame F and the cross-section of the guide ring G.

[0166] Understandably, in the first state of motion, when the difference between the projected area of ​​the first guide vane 1301 and the second guide vane 1302 within the outlet frame F and the cross-section of the guide ring G is less than 80%, the sidewall effect formed by the first guide vane 1301 and the second guide vane 1302 in the first state of motion will be weakened. When the airflow between the guide ring G and the outlet frame F is designed for upward airflow, the upward airflow volume will be insufficient. When the difference between the projected area of ​​the first guide vane 1301 and the second guide vane 1302 within the outlet frame F and the cross-section of the guide ring G is greater than 90%, in the first state of motion, the first guide vane 1301 and the second guide vane 1302 are prone to overlap and interference.

[0167] In the second motion state, the projected area of ​​the first guide vane 1301 and the second guide vane 1302 within the outlet frame F accounts for 5% to 10% of the difference between the cross-section of the outlet frame F and the cross-section of the guide ring G. It is understandable that when the difference between the projected area of ​​the first guide vane 1301 and the second guide vane 1302 within the outlet frame F and the cross-section of the guide ring G is less than 5%, the thickness of the first guide vane 1301 and the second guide vane 1302 will be too thin, resulting in insufficient rigidity and strength, and making them prone to deformation. When the difference between the projected area of ​​the first guide vane 1301 and the second guide vane 1302 within the outlet frame F and the cross-section of the guide ring G is greater than 10%, the first guide vane 1301 and the second guide vane 1302 will generate significant wind resistance between the guide ring G and the outlet frame F in the second motion state, resulting in insufficient airflow.

[0168] Optionally, such as Figure 8 As shown, the front and rear of the guide ring G are open, and an axial flow fan or a cross-flow fan is installed inside the guide ring G. The air drawn in by the axial flow fan or the cross-flow fan is discharged along the guide ring G towards the first air outlet A21.

[0169] In some embodiments, such as Figures 16-18 As shown, the indoor unit 1000 of the air conditioner includes: a casing A, an air outlet frame F, and a guide ring G.

[0170] The air conditioner indoor unit 1000 further comprises an air casing A, an air inlet A1 and a front air outlet A2 are arranged on the air casing A. That is, the air coming from the air inlet A1 can flow out through the front air outlet A2.

[0171] The air casing A further comprises an air outlet frame F arranged in the air casing A. The air outlet frame F comprises a left side plate F2 and a right side plate F3. The left side plate F2 and the right side plate F3 are arranged in the air casing A in a spaced-apart manner along the left-right direction. The air outlet frame F is fixed in the air casing A by the left side plate F2 and the right side plate F3. On the one hand, the left side plate F2 and the right side plate F3 are arranged in the air casing A in a spaced-apart manner along the left-right direction to form a flow channel for the air flow, thereby playing a role of air guiding. On the other hand, the air outlet frame F can be stably fixed on the air casing A by the left side plate F2 and the right side plate F3, thereby playing a role of limiting and fixing.

[0172] The air casing A further comprises a flow guide ring G arranged in the air outlet frame F. The flow guide ring G comprises a left side wall and a right side wall. The left side wall of the flow guide ring G and the left side plate F2 define a first sub-air duct A51 extending in the up-down direction. The right side wall of the flow guide ring G and the right side plate F3 define a second sub-air duct A52 extending in the up-down direction. In this way, the air coming from the air inlet A1 can flow through the inside of the flow guide ring G, or flow through the first sub-air duct A51 and the second sub-air duct A52 formed by the left side plate F3 and the flow guide ring G respectively, thereby having multiple air guiding branches, which is beneficial to expand the air supply range and improve the air supply effect. That is, the left side wall of the flow guide ring G and the left side plate F2 define the first sub-air duct A51 extending in the up-down direction. The right side wall of the flow guide ring G and the right side plate F3 define the second sub-air duct A52 extending in the up-down direction. The left side plate F3 and the flow guide ring G form left and right branches flowing in the up-down direction, which is beneficial to expand the air supply range, improve the air supply effect, and improve the user experience.

[0173] In some embodiments, as shown in Figure 16 and Figure 17 the front air outlet A2 is located at the front side of the flow guide ring G. The inner cavity of the flow guide ring G is in communication with the air inlet A1 and the front air outlet A2 respectively, so as to ensure that a part of the air coming from the air inlet A1 can enter the front air outlet A2 through the air guiding of the inner cavity of the flow guide ring G.

[0174] Specifically, as shown in Figure 16 and Figure 17 the air conditioner indoor unit 1000 further comprises a first fan D and a second fan E. The first fan D is arranged in the flow guide ring G to drive the air flow from the air inlet A1 to the front air outlet A2. The second fan E is arranged in the air casing A. In the length direction of the air casing A, the third air outlet A3 and the second fan E are respectively located at the opposite sides of the flow guide ring G to drive the air flow from the air inlet A1 to the front air outlet A2, and to drive the air flow from the air inlet A1 to the third air outlet A3 through the first sub-air duct A51 and the second sub-air duct A52.

[0175] It can be understood that the air sent by the air inlet A1 can be sucked by the first fan D and discharged from the front air outlet A2. The air sent by the air inlet A1 can also be sucked by the second fan E and driven to flow towards the front air outlet A2 and the third air outlet A3 after passing through the first sub-air duct A51 and the second sub-air duct A52. In this way, the air of the air inlet A1 can be guided by multiple fans, improving the range of air flow and thus improving the air supply effect of the air conditioner indoor unit 1000.

[0176] In some embodiments, as shown in Figure 4 The first sub-air duct A51 and the second sub-air duct A52 are symmetrically arranged relative to the flow guide ring G, and the minimum width of the first sub-air duct A51 and the second sub-air duct A52 is W1, which satisfies: 20mm≤W1≤60mm. It can be understood that the first sub-air duct A51 and the second sub-air duct A52 are symmetrically arranged relative to the flow guide ring G to serve as a flow passage for the airflow driven by the second fan E. If the width of the first sub-air duct A51 and the second sub-air duct A52 is too small, it is not conducive to the rapid discharge of air after heat exchange in the air conditioner, which can easily cause air to accumulate in the shell, increase the internal pressure, and pose a safety hazard. Therefore, the minimum width of the first sub-air duct A51 and the second sub-air duct A52 is set to 20mm≤W1≤60mm, which can ensure that the airflow flows through the first sub-air duct A51 and the second sub-air duct A52 within this range.

[0177] In some alternative embodiments, as shown in Figure 17 The shell A is provided with a volute I, and the second fan E is arranged in the volute I. The volute I has a volute I inlet I1 and a volute I outlet I2. The volute I inlet I1 is opposite to the air inlet A1, and the volute I outlet I2 is opposite to the flow guide ring G. In this way, the second fan E can suck the air of the air inlet A1 into the volute I inlet I1, and the air discharged from the volute I outlet I2 can flow towards the flow guide ring G.

[0178] Specifically, as shown in Figure 17 The width of the volute I outlet end is greater than the width of the flow guide ring G. That is, part of the air discharged from the volute I outlet I2 can pass through the blockage of the flow guide ring G, thereby being divided to flow through the first sub-air duct A51 and the second sub-air duct A52. Since the width of the volute I outlet end is greater than the width of the flow guide ring G, the air discharged from the volute I outlet I2 can also directly flow into the first sub-air duct A51 and the second sub-air duct A52, which is conducive to the rapid passage of airflow, thereby improving the air outlet efficiency of the air conditioner indoor unit 1000.

[0179] In some embodiments, as shown in Figure 8 and Figure 9As shown, the indoor unit 1000 of the air conditioner also includes longitudinal guide vanes 130, which are disposed between the casing A and the blocking member H. Each longitudinal guide vane 130 includes multiple vanes extending in the vertical direction, and the multiple longitudinal guide vanes 130 are arranged side by side in the horizontal direction. The length of the multiple longitudinal guide vanes 130 gradually decreases in the direction from the left and right sides toward the center of the blocking member H. In this way, the longitudinal guide vanes 130 can be used to guide the air flowing in the first air duct A4 and the second air duct A5 in the horizontal direction to further adjust the airflow direction and make the air outlet more uniform.

[0180] Specifically, such as Figure 8 and Figure 9 As shown, the indoor unit 1000 of the air conditioner also includes a horizontal guide vane 110. The horizontal guide vane 110 is disposed inside the casing A and located in front of the vertical guide vane 130. The horizontal guide vane 110 extends in the left and right direction and includes multiple horizontal guide vanes. The multiple horizontal guide vanes 110 are arranged side by side in the up and down direction. In this way, the vertical guide vane 130 can be used to guide the airflow delivered from the front air outlet A2 in the up and down direction to further adjust the airflow direction and make the airflow more uniform.

[0181] In some embodiments, the air conditioner indoor unit 1000 further includes: Figure 2 and Figure 3 As shown, the third air guiding assembly J13 includes multiple first air guiding plates J131. The first air guiding plates J131 are rotatably disposed at the third air outlet A3 to open or close the third air outlet A3. The rotation axis of the first air guiding plates J131 extends along the width direction of the casing A. In this way, the first air guiding plates J131 can rotate vertically, allowing the air delivered from the third air outlet A3 to be guided by the multiple first air guiding plates J131 to adjust the airflow direction, increase the airflow range, and make the airflow more uniform. Simultaneously, when the first air guiding plates J131 are closed, they also have a dust-proof function, protecting the cleanliness of the air conditioner's interior when not in operation.

[0182] Specifically, such as Figure 2 and Figure 3 As shown, the third air guide assembly J13 also includes a second air guide plate, which is rotatably disposed at the third air outlet A3. Along the airflow direction, the second air guide plate is located upstream of the first air guide plate J131, and its rotation axis extends along the length of the housing A. This allows the second air guide plate to rotate in the left-right direction, so that the air delivered from the third air outlet A3 can be guided by both the first air guide plate J131 and the second air guide plate, further increasing the airflow range and enhancing the airflow effect.

[0183] In some embodiments, such as Figures 2-7 As shown, the indoor unit 1000 of the air conditioner includes: a casing A and a blocking component H.

[0184] The shell A is provided with an air inlet A1 and a second air outlet A22 arranged on the front surface of the shell A. The shell A defines a second air duct A5 communicating with the air inlet A1 and the second air outlet A22, and the second air duct A5 extends in the vertical direction. That is, the air of the air inlet A1 can flow out of the second air outlet A22 along the second air duct A5.

[0185] The blocking piece H is arranged in the second air duct A5, and the blocking piece H is configured to block the air flow in the second air duct A5 to form a positive pressure area upstream of the blocking piece H. The air in the positive pressure area can flow out of the second air outlet A22. That is, the air flow of the second air duct A5 forms a positive pressure area upstream of the blocking piece H, and the air in the positive pressure area will automatically flow to the normal pressure area, so that the air flow of the second air duct A5 can flow out of the second air outlet A22. That is, by arranging the blocking piece H to block the air flow in the second air duct A5 to form a positive pressure area, the air flow of the second air duct A5 can change direction and flow out of the second air outlet A22, thereby improving the air supply efficiency.

[0186] According to one embodiment of the present application, as shown in Figure 4 The blocking piece H includes a lower blocking plate H1. The cross section of the lower blocking plate H1 in the front-rear direction is arc-shaped, the lower blocking plate H1 is arranged protruding downward, and the lower blocking plate H1 extends in the front-rear direction. In this way, the lower blocking piece H extending in the front-rear direction can block the air flow from the second air duct A5. Since the cross section of the lower blocking plate H1 in the front-rear direction is arc-shaped and the lower blocking plate H1 is arranged protruding downward, the lower blocking plate H1 can effectively guide the air flow of the second air duct A5 into the first and second sub-air ducts A51 and A52, and the arc-shaped arrangement will be conducive to the rapid diversion of air and increase the amount of air entering.

[0187] Specifically, as shown in Figure 2 and Figure 4 One end of the lower blocking plate H1 is in contact with the inner wall of the second air duct A5, and the other end of the lower blocking plate H1 is arranged spaced apart from the inner wall of the second air duct A5, and the second sub-air duct A52 is defined between the other end of the lower blocking plate H1 and the second air duct A5. In this way, the one end of the lower blocking plate H1 in contact with the inner wall of the second air duct A5 can block the air flow from the second air duct A5, and the other end of the blocking plate arranged spaced apart from the inner wall of the second air duct A5 can guide the air flow to flow in the second air duct A5.

[0188] Further, as shown in Figure 4 The blocking piece H further includes a longitudinal blocking plate H3. The longitudinal blocking plate H3 is connected to the other end of the lower blocking plate H1 and extends upward, and the second sub-air duct A52 is defined between the longitudinal blocking plate H3 and the inner wall of the second air duct A5. That is, the longitudinal blocking plate H3 can guide the air flow from the other end of the lower blocking plate H1 to flow upward along the longitudinal blocking plate H3.

[0189] In some alternative embodiments, as shown in Figure 3 and Figure 4 the cross section of the longitudinal blocking plate H3 in the front-rear direction is arc-shaped, and the longitudinal blocking plate H3 is convexly arranged towards the second air duct A5. In this way, the convex arrangement of the longitudinal blocking plate towards the second air duct A5 can block the air flow from the lower blocking plate H1 to flow along the second sub-air duct A52, and the arc-shaped arrangement can facilitate the rapid diversion of the air flow and increase the amount of air entering.

[0190] In some alternative embodiments, the blocking piece H further comprises: an upper blocking plate H2. Two ends of the upper blocking plate H2 are respectively connected with the longitudinal blocking plate H3 and the inner wall of the second air duct A5, wherein the lower blocking plate H1, the longitudinal blocking plate H3 and the upper blocking plate H2 jointly define the first air duct A4 extending through in the front-rear direction. On the one hand, the upper blocking plate H2, the lower blocking plate H1 and the total blocking plate jointly define the first air duct A4 extending through in the front-rear direction, so that the air flow can flow through the first air duct A4. On the other hand, the upper blocking plate H2, the lower blocking plate H1 and the longitudinal blocking plate can also jointly define the second air duct A5 extending through in the up-down direction with the cabinet A.

[0191] Specifically, as shown in Figure 4 the cross section of the upper blocking plate H2 in the front-rear direction is arc-shaped and convexly arranged upwards, and the upper blocking plate H2 is arc-shapedly and smoothly connected with the longitudinal blocking plate H3 to facilitate the rapid passing of the air flow and reduce the energy loss of the air flow.

[0192] In some embodiments, as shown in Figure 4 the air conditioner indoor unit 1000 further comprises an air outlet frame F arranged in the cabinet A, and the blocking piece H is arranged in the air outlet frame F, wherein the first sub-air duct A51 and the second sub-air duct A52 are jointly defined by the outer wall of the blocking piece H and the inner wall of the air outlet frame F. That is, the air sent by the second air duct A5 will flow along the first sub-air duct A51 and the second sub-air duct A52 between the outer wall of the blocking piece H and the inner wall of the air outlet frame F under the blocking of the blocking piece H, so that the air flow in the second air duct A5 is effectively diverted, and the air outlet is more uniform, reducing the poor experience caused by excessive concentration of air force.

[0193] In some embodiments, as shown in Figures 2-7 the air conditioner indoor unit 1000 comprises: a cabinet A and a blocking piece H.

[0194] The cabinet A is provided with an air inlet A1 and a second air outlet A22 arranged on the front surface of the cabinet A, and the cabinet A defines a second air duct A5 communicating the air inlet A1 and the second air outlet A22, which extends in the vertical direction. That is, the air of the air inlet A1 can flow through the second air duct A5 and flow out of the second air outlet A22.

[0195] The blocking piece H is arranged in the second air duct A5 to separate the second air duct A5 into the first sub-air duct A51 and the second sub-air duct A52 which are spaced apart on the left and right sides. The leeward side of the blocking piece H is formed with a merging area which communicates with the first sub-air duct A51 and the second sub-air duct A52. The air flowing through the first sub-air duct A51 and the second sub-air duct A52 merges in the merging area and then flows out of the second air outlet A22 along the direction of the blocking piece H. In this way, when the air of the air inlet A1 flows through the second air duct A5, the blocking piece H can divide the air flow into two parts, one part flows along the first sub-air duct A51, and the other part flows along the second sub-air duct A52, and then merges in the merging area and flows out of the second air outlet A22 along the extension direction of the blocking piece H.

[0196] It can be understood that the first sub-air duct A51, the second sub-air duct A52 and the merging area formed between the blocking piece H and the shell A guide the air flow of the second air duct A5 and discharge it towards the second air outlet A22. Thus, the air flow can flow through the first channel and the second channel, so that the air flow is effectively divided, and the air outlet is more uniform. That is, by arranging the blocking piece H in the second air duct A5 to form the first sub-air duct A51, the second sub-air duct A52 and the merging area, the air flow of the second air duct A5 is effectively divided, and the air outlet is more uniform, improving the user experience.

[0197] In some embodiments, as shown in Figure 3 and 4 , the blocking piece H extends in a direction perpendicular to the air duct and towards the second air outlet A22. That is, the blocking piece H can block the air flowing through the air duct, guide the air flow into the first sub-air duct A51 and the second sub-air duct A52, and then send the air flowing through the first sub-air duct A51 and the second sub-air duct A52 out of the second air outlet A22 along the direction in which the blocking piece H extends towards the second air outlet A22. It should be noted that the inner cavity of the blocking piece H can be used to guide the air flow, which is also called a flow guide ring G when used for this function.

[0198] In some embodiments, as shown in Figure 3 , the inner cavity of the blocking piece H is formed with the first air duct A4, the first air duct A4 is provided with the first air fan D, and the end of the blocking piece H towards the second air outlet A22 is formed with the first air outlet A21. The first air outlet A21 is located on the front side of the first sub-air duct A51, the second sub-air duct A52 and the merging area. In this way, the air of the air inlet A1 sucked by the first air fan D can flow forward along the first air duct A4 and flow to the first air outlet A21 through the flow guide of the inner cavity of the blocking piece H. In this way, the air of the air inlet A1 can be guided by multiple channels, which is beneficial to further improve the range of air flow, thereby improving the air supply effect of the air conditioner indoor unit 1000.

[0199] Optionally, as shown in Figure 4As shown, the lower baffle H1 is located in the middle of the casing A in the left-right direction. Further comprising: a left baffle H31 and a right baffle H32. The left baffle H31 is connected to the left end of the lower baffle H1 and extends upward, and the first sub-air duct A51 is defined between the left baffle H31 and the inner wall of the casing A. The right baffle H32 is connected to the right end of the lower baffle H1 and extends upward, and the second sub-air duct A52 is defined between the right baffle H32 and the inner wall of the casing A. That is, under the guidance of the lower baffle H1, the airflow will enter the first sub-air duct A51 defined between the left baffle H31 and the inner wall of the casing A and the second sub-air duct A52 defined between the right baffle H32 and the inner wall of the casing A, respectively, and flow in the direction in which the left baffle H31 and the right baffle H32 extend upward.

[0200] Further, as shown, Figure 4 the cross section of the left baffle H31 and the right baffle H32 in the front-back direction is arc-shaped, and the opposite sides of the left baffle H31 and the right baffle H32 are concave, respectively. In this way, the arc-shaped opposite sides of the left baffle H31 and the right baffle H32 can guide the airflow from the lower baffle H1, and the arc-shaped arrangement will be conducive to the rapid diversion of the wind and increase the amount of incoming wind.

[0201] In some optional embodiments, as shown, Figure 4 the left baffle H31 and the right baffle H32 are respectively arc-shaped with the lower baffle H1 to facilitate the rapid passage of airflow and reduce energy loss of the airflow.

[0202] In some optional embodiments, as shown, Figure 4 the baffle H further comprises an upper baffle H2, both ends of the upper baffle H2 are connected to the left baffle H31 and the right baffle H32, respectively, and the lower baffle H1, the left baffle H31, the right baffle H32 and the upper baffle H2 together define the first air duct A4 which penetrates in the front-back direction. On the one hand, the upper baffle H2, the lower baffle H1, the left baffle H31 and the right baffle H32 together define the first air duct A4 which penetrates in the front-back direction, so that the airflow can flow through the first air duct A4. On the other hand, the upper baffle H2, the lower baffle H1, the left baffle H31 and the right baffle H32 can also define the second air duct A5 which penetrates up and down with the air outlet frame F.

[0203] Specifically, as shown, Figure 4 the cross section of the upper baffle H2 in the front-back direction is arc-shaped and convex upward, and the upper baffle H2 is arc-shaped with the left baffle H31 and the right baffle H32 to facilitate the rapid passage of airflow and reduce energy loss of the airflow.

[0204] In some embodiments, as shown, Figure 8 andFigure 9 As shown, the air conditioner indoor unit 1000 further comprises first air guide assemblies J11, which are arranged between the casing A and the blocking piece H. Each first air guide assembly J11 comprises a plurality of longitudinal vanes 130 extending in the up-down direction, which are arranged in the left-right direction, wherein the plurality of longitudinal vanes 130 gradually decrease in length in the direction from the left and right sides to the center of the blocking piece H. In this way, the longitudinal vanes 130 can be used to guide the air flowing in the first air duct A4 and the second air duct A5 in the left-right direction, so as to further adjust the flow direction of the air flow, and make the air outlet more uniform.

[0205] In some embodiments, as shown in Figure 8 and Figure 9 Further comprising second air guide assemblies J12, which are arranged in the casing A and located in front of the first air guide assemblies J11. The second air guide assemblies J12 comprise a plurality of transverse vanes 110 extending in the left-right direction, which are arranged in the up-down direction. In this way, the transverse vanes 110 can be used to guide the air flow sent out of the front air outlet A2 in the up-down direction, so as to further adjust the flow direction of the air flow, and make the air outlet more uniform.

[0206] In some embodiments, as shown in Figure 7 The air conditioner indoor unit 1000 further comprises an air guide cover N, which is arranged at the front end of the blocking piece H and is configured to guide the air flow passing through it to be sent out spirally. In this way, the air at the first air outlet A21 can be further guided by the air guide cover N, so that the wind sucked in by the motor D2 is further concentrated, and is not easy to disperse at the first air outlet A21, thereby enhancing the air outlet strength and air outlet volume of the first air outlet A21, and also increasing the air outlet volume and air supply range of the air conditioner indoor unit 1000.

[0207] In some embodiments, as shown in Figures 16-18 The air conditioner indoor unit 1000 comprises a casing A, a flow guide ring G, and an axial flow fan D1.

[0208] The casing A is formed with an air inlet A1 and a front air outlet A2. The flow guide ring G is arranged in the casing A, and the flow guide ring G defines a first air duct A4 for communicating the air inlet A1 and the front air outlet A2 in the flow guide ring G. The plane where the rear end of the flow guide ring G is located is the air guide surface G1. In this way, the air flowing from the air inlet A1 can flow to the front air outlet A2 through the guidance of the air guide ring.

[0209] The axial flow fan D1 is rotatably arranged in the first air duct A4, and the rear end blade tip D12 of the axial flow fan D1 extends backward beyond the air guide surface G1. In this way, the distance between the axial flow fan D1 and the air inlet A1 is shortened, the air suction range of the axial flow fan D1 is expanded, the air volume sucked by the axial flow fan D1 is increased, and thus the air supply effect of the air conditioner indoor unit 1000 is improved. At the same time, the internal structure of the air conditioner indoor unit 1000 is more compact, which is conducive to the miniaturization of the air conditioner indoor unit 1000. That is, by extending the rear end blade tip D12 of the axial flow fan D1 backward beyond the air guide surface G1, the distance between the axial flow fan D1 and the air inlet A1 is shortened, the air suction range of the axial flow fan D1 is expanded, the air volume sucked by the axial flow fan D1 is increased, and thus the air supply effect of the air conditioner indoor unit 1000 is improved. At the same time, the internal structure of the air conditioner indoor unit 1000 is more compact, which is conducive to the miniaturization of the air conditioner indoor unit 1000.

[0210] In some embodiments, as shown in Figs. 1 and 2, the rear end blade tip D12 of the axial flow fan D1 extends backward beyond the air guide surface G1. Figure 17 and 18 In some embodiments, the distance L1 by which the rear end blade tip D12 of the axial flow fan D1 extends backward beyond the air guide surface G1 ranges from 1 mm to 50 mm. That is, the distance by which the rear end blade tip D12 of the axial flow fan D1 extends backward beyond the air guide surface G1 is limited within a reasonable range. In this way, under the premise of protecting the safety of the rear end blade tip D12, the distance between the axial flow fan D1 and the air inlet A1 can be shortened during rotation of the axial flow fan D1, so as to expand the air suction range of the axial flow fan D1.

[0211] The heat exchanger B is arranged in the casing A and located between the air inlet A1 and the front air outlet A2, and the axial flow fan D1 is located in front of the heat exchanger B. In this way, the axial flow fan D1 and the heat exchanger B are arranged in front of and behind each other in the transverse direction, so that the structure arrangement in the casing A is reasonable and compact, and the space in the casing A is fully utilized, which is conducive to reducing the volume of the entire casing A.

[0212] The axial flow fan D1 has a first predetermined distance L2 between the rear end blade tip D12 and the heat exchanger B. In this way, the rear end blade tip D12 of the axial flow fan D1 is kept at a certain distance from the heat exchanger B, so as to protect the safety of the rear end blade tip D12 during rotation of the axial flow fan D1.

[0213] The air guide cover N is arranged on the air guide ring G and covers the front end of the first air duct A4. It can be understood that the air guide cover N arranged on the air guide ring G1 can play a guiding role for the airflow.

[0214] The axial flow fan D1 has a second predetermined distance L3 between the front end blade tip D11 and the air guide cover N. In this way, the front end blade tip D11 of the axial flow fan D1 is kept at a certain distance from the air guide cover N, so as to protect the safety of the front end blade tip D11 during rotation of the axial flow fan D1.

[0215] Specifically, as shown in Figure 17 the first predetermined distance L2 between the rear end blade tip D12 of the axial flow fan D1 and the heat exchanger B is not less than 18 mm, and the second predetermined distance L3 between the front end blade tip D11 of the axial flow fan D1 and the air deflector N is not less than 18 mm. In this way, the front end tip angle and the rear end tip angle of the axial flow fan D1 are protected from interference with other surrounding components during movement, thereby preventing damage to the axial flow fan D1. It should be noted that the first predetermined distance L2 between the rear end blade tip D12 of the axial flow fan D1 and the heat exchanger B and the second predetermined distance L3 between the front end blade tip D11 of the axial flow fan D1 and the air deflector N are not the larger the better, otherwise, the front-to-back dimension of the entire air conditioner indoor unit 1000 will be too large, occupying a large space and having a large mass.

[0216] It can be understood that designing the first predetermined distance L2 between the rear end blade tip D12 of the axial flow fan D1 and the heat exchanger B to be not less than 18 mm and the second predetermined distance L3 between the front end blade tip D11 of the axial flow fan D1 and the air deflector N to be not less than 18 mm provides a reasonable installation position G2 of the fan blades of the axial flow fan, which improves the air supply efficiency of the first fan D while ensuring the safety distance of the axial flow fan D1 before and after.

[0217] In some optional embodiments, as shown in Figure 17 the radius of the wind-swept area of the front end blade tip D11 of the axial flow fan D1 is equal to the radius of the wind-swept area of the rear end blade tip D12 of the axial flow fan D1. That is, the radial outer end of the front end blade tip D11 and the radial outer end of the rear end blade tip D12 are located on the same longitudinal plane, which ensures the uniformity of airflow

[0218] Specifically, the radius of the wind-swept area of the front end blade tip D11 of the axial flow fan D1 is 125 mm-130 mm, and the radius of the wind-swept area of the rear end blade tip D12 of the axial flow fan D1 is also 125 mm-130 mm. In a specific embodiment, the radius of the wind-swept area of the front end blade tip D11 of the axial flow fan D1 and the radius of the wind-swept area of the rear end blade tip D12 of the axial flow fan D1 can both be 128 mm, which maximizes the area of the wind-swept area of the front end blade tip D11 and the rear end blade tip D12, thereby improving the air supply efficiency of the first fan D and also shortening the length of the first air duct A4.

[0219] In some optional embodiments, as shown in Figure 17As shown in the figure, the vertical distance between the outer periphery of the wind-swept area of the rear end blade tip D12 and the inner circumferential wall of the heat exchanger B is not less than 18 mm. It can be understood that the minimum distance between the movement plane of the rear end blade tip D12 of the axial flow fan D1 and the inner wall surface of the heat exchanger B is the vertical distance between the outer periphery of the wind-swept area of the rear end blade tip D12 and the inner circumferential wall of the heat exchanger B, which is not less than 18 mm, so as to ensure that the rear end blade tip D12 of the axial flow fan D1 does not interfere with the heat exchanger B during the rotating movement, and the normal work of the axial flow fan D1 and the heat exchanger B is protected.

[0220] In some embodiments, as shown in Figure 17 and 18 , the distance between the movement plane of the front end blade tip D11 of the axial flow fan D1 and the movement plane of the rear end blade tip D12 of the axial flow fan D1 is 105-115 mm. Specifically, the distance between the movement plane of the front end blade tip D11 of the axial flow fan D1 and the movement plane of the rear end blade tip D12 of the axial flow fan D1 can be 108 mm, that is, the length of the wind-swept area of the axial flow fan D1 in the front-rear direction is 108 mm, so that the axial flow fan occupies a small space under the condition of meeting the air supply requirement, which is conducive to the miniaturization of the air conditioner indoor unit 1000.

[0221] In some optional embodiments, as shown in Figure 16 , the air conditioner indoor unit 1000 further comprises a motor D2 and a motor support D22, the motor support D22 is arranged at the front end of the flow guide ring G and comprises a cylindrical fixed part, the motor D2 is arranged on the fixed part, and the motor shaft D21 passes through the fixed part rearward and is connected in transmission with the axial flow fan D1, and the air guide cover N is arranged around the outside of the fixed part. That is, the motor support D22 limits and fixes the motor D2 through the fixed part, and the motor shaft D21 passes through the fixed part rearward and is connected in transmission with the axial flow fan D1, so that when the motor D2 works, the axial flow fan D1 will relatively rotate to guide the flow of air under the transmission of the motor shaft D21.

[0222] Specifically, as shown in Figure 16 , the motor support D22 further comprises a plurality of connecting rods, and the plurality of connecting rods are arranged radially on the outside of the fixed part and connect the fixed part to the flow guide ring G. In this way, the arrangement of the connecting rods is conducive to increasing the rigidity of the motor support D22, improving the stability of the motor support D22, and further improving the stability of the motor D2 in operation. At the same time, the fixed part is connected to the flow guide ring G, which can limit and fix the motor support D22.

[0223] In some embodiments, as shown in Figures 7-24As shown, the air conditioner indoor unit 1000 comprises a guide ring G, a first fan D and a guide cover N. The guide ring G is formed with a first air inlet A1 and a first air outlet A21. The first fan D is arranged in the guide ring G and is configured to drive air to flow from the first air inlet A1 to the first air outlet A21. The guide cover N is arranged at the first air outlet A21 of the guide ring G and is provided with a static blade N1 configured to rotate air passing through the guide cover N out of the first air outlet A21 at a predetermined angle.

[0224] It can be understood that the first fan D can suck air from the first air inlet A1 and guide the air to flow to the first air outlet A21 through the guide ring. At this time, the guide cover N arranged at the first air outlet A21 can further guide the air, and the static blade N1 can further rotate the air out of the first air outlet A21 at a predetermined angle. Thus, the air sucked by the motor D2 is further concentrated and is not easy to be dispersed at the first air outlet A21, thereby enhancing the air outlet strength and air outlet volume of the first air outlet A21, and increasing the air outlet volume and air supply range of the air conditioner indoor unit 1000.

[0225] In some embodiments, as shown in Figure 19 the static blade N1 is movably arranged on the guide cover N between a first position and a second position. In the first position, the static blade N1 opens the first air outlet A21, and in the second position, the static blade N1 closes the first air outlet A21. In this way, when the static blade N1 opens the first air outlet A21, air from the first air inlet A1 can flow through the guide cover N and out of the first air outlet A21, and the guide cover N can guide the flow direction of the air to expand the air outlet range. When the static blade N1 closes the first air outlet A21, the static blade N1 can also block dust and other particles in the external air, thereby improving the cleanliness of the interior of the air conditioner indoor unit 1000.

[0226] Specifically, as shown in Figure 20 the guide cover N comprises a spiral flow mounting frame N2 and a blade driving plate N3. The spiral flow mounting frame N2 is fixed at the first air outlet A21 and comprises an outer ring N21 and a fixed ring N22 located at the middle of the outer ring N21. The blade driving plate N3 is arranged on the spiral flow mounting frame N2 and is rotatable about the outer ring N21. One end of the static blade N1 is connected to the fixed ring N22 and is rotatable in the radial direction relative to the fixed ring N22, and the other end of the static blade N1 is connected to the blade driving plate N3 to drive the static blade N1 to move between the first position and the second position. That is, one end of the static blade N1 is connected to the fixed ring N22, so that the spiral flow mounting frame N2 can limit the static blade N1, and one end of the static blade N1 is rotatable in the radial direction relative to the fixed ring N22, so that when the blade driving plate N3 drives the other end of the static blade N1 to rotate, one end of the static blade N1 can rotate in the radial direction relative to the outer ring N21 of the spiral flow mounting frame N2 together with the other end of the static blade N1.

[0227] Further, as shown in Figure 20 the peripheral wall of the fixed ring N22 is provided with a mounting hole N221, and one end of the vane N1 passes through the mounting hole N221 and is rotatable in the mounting hole N221. That is, the mounting hole N221 connects the one end of the vane N1 with the fixed ring N22 in rotation, so that the one end of the vane N1 can rotate relatively in the mounting hole N221.

[0228] (4) In some optional embodiments, as shown in Figure 20 the vane driving plate N3 is sleeved outside the outer ring N21, wherein the outer ring N21 is provided with a mounting groove N212, and the vane N1 is supported in the mounting groove N212. It can be understood that the vane driving plate N3 is sleeved outside the outer ring N21, so that the outer ring N21 can limit the vane driving plate N3. The vane N1 is supported in the mounting groove N212 provided on the outer ring N21, and the mounting groove N212 can limit the vane N1, and the vane N1 is supported on the outer ring N21, which can improve the stability of the vane N1 installation.

[0229] In some optional embodiments, the vane N1 comprises a vane N10 and a piston shaft N12. One end of the vane N10 is connected with the fixed ring N22, and the other end of the vane N10 is provided with a sleeve N101. The first end of the piston shaft N12 is connected with the vane driving plate N3, and the second end of the piston shaft N12 is telescopic in the sleeve N101 to drive the vane N10 to move between the first position and the second position. That is, the first end of the piston shaft N12 is relatively rotated under the driving of the vane driving plate N3, so that the second end of the piston shaft N12 is telescopic to drive the other end of the vane N10 to rotate, and the one end of the vane N10 is rotated with the other end of the vane N10 following the fixed ring N22, so that the whole vane N10 can move between the first position and the second position.

[0230] Specifically, as shown in Figure 21 the first end of the piston shaft N12 is connected with the vane driving plate N3 through a ball hinge. It can be understood that the ball hinge makes the rotation between the first end of the piston shaft N12 and the vane driving plate N3 more flexible, which can expand the wind guiding range of the vane N10.

[0231] In some optional embodiments, as shown in Figure 22 and 23As shown, the vane driving plate N3 is provided with a guide groove N31 extending perpendicularly to the direction of the vane driving plate N3, and the air conditioner indoor unit 1000 further comprises a driving plate driving device P, which comprises a driving plate motor P1 and a crank P2. One end of the crank P2 is connected to the motor shaft P12 of the driving plate motor, and the other end of the crank P2 is movable reciprocatingly in the guide groove N31, and the one end of the crank P2 is different in axis from the other end of the crank P2. That is, in the working state of the driving plate motor P1, the motor shaft P12 of the driving plate motor drives the one end of the crank P2 to rotate, and the other end of the crank P2 is different in axis from the one end of the crank P2, so that the other end of the crank P2 can move in the guide groove N31, thereby driving the vane driving plate N3 to rotate relatively.

[0232] The one end of the crank P2 is driven to rotate relatively, and the other end of the crank P2 is different in axis from the one end of the crank P2, so that the other end of the crank P2 can move in the guide groove N31, thereby driving the vane driving plate N3 to rotate relatively.

[0233] In some optional embodiments, as shown in Figure 20 As shown, the air guide cover N further comprises a driving bottom plate N4. The driving bottom plate N4 is sleeved outside the outer ring N21, the vane driving plate N3 is arranged above the driving bottom plate N4, and a positioning structure N41 is arranged between the driving bottom plate N4 and the vane driving plate N3 to enable the vane driving plate N3 and the driving bottom plate N4 to rotate synchronously. In this way, the driving bottom plate N4 can fix the vane driving plate N3, increase the rigidity of the vane driving plate N3, and thus make the rotation of the vane driving plate N3 more stable.

[0234] Optionally, the positioning structure N41 comprises a positioning column N411 and a positioning sleeve N412, and the positioning column N411 and the positioning sleeve N412 are sleeved with each other. On the one hand, the positioning column N411 and the positioning sleeve N412 can play the role of a reinforcing rib, and can further improve the rigidity of the driving bottom plate N4 and the vane driving plate N3; on the other hand, the positioning column N411 and the positioning sleeve N412 are simple to install and convenient to operate.

[0235] Specifically, as shown in Figure 20 As shown, the driving bottom plate N4 and the vane driving plate N3 are respectively provided with through holes arranged corresponding to each other. In this way, the through holes provide a space for the connecting part of the driving bottom plate N4 and the vane driving plate N3, so that the driving bottom plate N4 and the vane driving plate N3 can be connected through a connecting part, and the driving bottom plate N4 has a limiting and fixing effect on the vane driving plate N3, thereby improving the stability of the relative movement of the vane driving plate N3.

[0236] In some optional embodiments, as shown in Figure 20As shown, the air deflector N further comprises: a rotating vane pressing plate N5. The rotating vane pressing plate N5 is fixed on the rotating installation frame N2, and the stationary vane N1 is arranged between the rotating vane pressing plate N5 and the rotating installation frame N2. In this way, during rotation of the stationary vane N1, the rotating vane pressing plate N5 and the rotating installation frame N2 on both sides of the stationary vane N1 can reduce the risk of the stationary vane N1 touching fingers, thereby improving the safety of the air conditioner indoor unit 1000.

[0237] In some embodiments, as shown in Figure 20 As shown, the stationary vane N1 comprises a plurality of stationary vanes N1 arranged around the circumference of the fixing ring N22. It can be understood that the arrangement of the plurality of stationary vanes N1 can reduce the design length of a single stationary vane N1 and increase the design flexibility of the stationary vane N1. At the same time, in order to ensure the guidance of the stationary vane N1 to the air at the first air outlet A21, the plurality of stationary vanes N1 are arranged around the circumference of the fixing ring N22 so that the distance between adjacent stationary vanes N1 in the circumferential direction is appropriate, thereby ensuring sufficient air guiding effect and small air resistance.

[0238] In some embodiments of the present application, as shown in Figure 20 As shown, the air deflector N is provided with a plurality of mounting lugs N6, the outer wall of the guide ring G is provided with a plurality of mounting positions G2, and the plurality of mounting lugs N6 and the plurality of mounting positions G2 are one-to-one corresponding and mounted. The mounting lug N6 provides a specific mounting position G2 for the fixing of the air deflector N and the guide ring, so that the air deflector N is connected to the guide ring G. At the same time, the mounting lug N6 and the mounting position G2 are simple to install and easy to operate.

[0239] In some embodiments, as shown in Figure 20 As shown, the air deflector N comprises an inner ring mounting ring N7 and an outer ring mounting ring N8 wound outside the inner ring mounting ring N7, and two ends of the plurality of stationary vanes N1 are connected to the inner ring mounting ring N7 and the outer ring mounting ring N8, respectively. In this way, the inner ring mounting ring N7 and the outer ring mounting ring N8 limit and fix the stationary vane N1, so that the plurality of stationary vanes N1 can be stably connected to the inner ring mounting ring N7 and the outer ring mounting ring N8, thereby improving the stability of movement of the plurality of stationary vanes N1.

[0240] In some embodiments, as shown in Figure 20 As shown, the plurality of stationary vanes N1 are fixed on the inner ring mounting ring N7 and the outer ring mounting ring N8 in a radial manner. Here, the space between the inner ring mounting ring N7 and the outer ring mounting ring N8 can be used for air circulation, and the stationary vane N1 is arranged in a radial manner between the inner ring mounting ring N7 and the outer ring mounting ring N8, so as to guide and further gather the air flowing through in the maximum range and output to the first air outlet A21.

[0241] In some embodiments, as shown in Figure 19 and Figure 20As shown, the cross section of the stationary blade N1 in the fairing N is 5% to 15% of the difference between the cross section of the fairing N and the cross section of the inner ring mounting ring N7. That is, the stationary blade N1 arranged between the guide ring G and the inner ring mounting ring N7 occupies part of the air flow space. In order to ensure the strength of the fairing N itself and the guiding effect of the fairing N on the wind, the cross section of the stationary blade N1 in the fairing N is 5% to 15% of the difference between the cross section of the fairing N and the cross section of the inner ring mounting ring N7. Here, when the cross section of the stationary blade N1 in the fairing N is 5% to 15% of the difference between the cross section of the fairing N and the cross section of the inner ring mounting ring N7, the fairing N has sufficient structural strength and good guiding effect on the wind.
