For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0080] Reference below Figure 1-Figure 24 An air conditioner indoor unit 1000 according to an embodiment of the present invention is described.

[0081] According to an embodiment of the present invention, the air conditioner indoor unit 1000 is as follows: Figure 2-Figure 7 As shown, it includes: a casing A and a blocking member H.

[0082] The housing A is provided with an air inlet A1 and a second air outlet A22 provided on the front surface of the housing A. A second air duct A5 connecting the air inlet A1 and the second air outlet A22 is defined in the housing A. The second air duct A5 extends in the vertical direction. That is, the air in the air inlet A1 can flow out of the second air outlet A22 along the second air duct A5.

[0083] The blocking member H is disposed in the second air duct A5, and is configured to block the air flow in the second air duct A5, so as to form a positive pressure area upstream of the blocking member H. The air in the positive pressure area can flow out from the second air outlet A22. In other words, the air in the second air duct A5 flows into the blocking member H to form a positive pressure area, and since the air in the positive pressure area automatically flows to the normal pressure area, the airflow in the second air duct A5 can flow out from the second air outlet A22.

[0084] According to the indoor unit of the air conditioner according to the embodiment of the present invention, a blocking member H is provided to block the air flow in the second air duct A5 to form a positive pressure area, so that the airflow in the second air duct A5 can change direction and flow out from the second air outlet A22, thereby improving the air supply efficiency.

[0085] According to one embodiment of the present invention, Figure 4 As shown, the blocking member H includes: a lower blocking plate H1. The cross section of the lower blocking plate H1 in the front-to-back direction is arc-shaped, the lower blocking plate H1 is convexly arranged downward, and the lower blocking plate H1 extends in the front-to-back direction. In this way, the lower blocking member H extending in the front-to-back direction can block the airflow from the second air duct A5. Since the cross section of the lower blocking plate H1 in the front-to-back direction is arc-shaped and convexly arranged downward, the lower blocking plate H1 can effectively introduce the airflow of the second air duct A5 into the first sub-air duct A51 and the second sub-air duct A52. At the same time, the arc-shaped setting will be conducive to the rapid diversion of wind and increase the incoming air volume.

[0086] Specifically, Figure 2 and Figure 4 As shown, one end of the lower blocking plate H1 contacts the inner wall of the second air duct A5, and the other end of the lower blocking plate H1 is spaced apart from the inner wall of the second air duct A5, wherein a second sub-air duct A52 is defined between the other end of the lower blocking plate and the second air duct A5. Thus, the one end of the lower blocking plate H1 in contact with the inner wall of the second air duct A5 can block the airflow from the second air duct A5, and the other end of the blocking plate spaced apart from the inner wall of the second air duct A5 can guide the airflow to flow in the second air duct A5.

[0087] Furthermore, if Figure 4 As shown, the blocking member 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 a 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 airflow from the other end of the lower blocking plate H1 to flow upward along the longitudinal blocking plate H3.

[0088] In some optional embodiments, such as Figure 3 and Figure 4As shown, the cross section of the longitudinal blocking plate H3 in the front-to-back direction is arc-shaped, and the longitudinal blocking plate H3 is protruded toward the second air duct A5. In this way, the protruding shape of the longitudinal blocking plate toward the second air duct A5 can block the airflow from the lower blocking plate H1 and make it flow along the second sub-air duct A52, and the arc-shaped setting will be conducive to the rapid diversion of wind and increase the incoming air volume.

[0089] In some optional embodiments, the blocking member H further includes: an upper blocking plate H2. The two ends of the upper blocking plate H2 are respectively connected to 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 a first air duct A4 that runs through the front-to-back direction. On the one hand, the upper blocking plate H2, the lower blocking plate H1 and the main stop plate jointly define the first air duct A4 that runs through the front-to-back direction, so that the airflow can flow along the first air duct A4. On the other hand, the upper blocking plate H2, the lower blocking plate H1 and the longitudinal stop plate can also jointly define a second air duct A5 that runs through the upper and lower parts with the housing A.

[0090] Specifically, Figure 4 As shown, the cross section of the upper blocking plate H2 in the front-to-back direction is arc-shaped and protrudes upward, and there is an arc transition between the upper blocking plate H2 and the longitudinal blocking plate H3 to facilitate the rapid passage of airflow and reduce energy loss of airflow.

[0091] In some embodiments, Figure 4 As shown, the air conditioner indoor unit 1000 further includes an air outlet frame F, which is arranged in the housing A, and a blocking member H is arranged in the air outlet frame F, wherein the first sub-air duct A51 and the second sub-air duct A52 are defined by the outer wall of the blocking member H and the inner wall of the air outlet frame F. That is, the air sent from 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 member H and the inner wall of the air outlet frame F under the blocking of the blocking member 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 wind force.

[0092] In some embodiments, Figure 2-Figure 7 As shown, the air conditioner indoor unit 1000 includes: a casing A and a blocking member H.

[0093] The housing A is provided with an air inlet A1 and a second air outlet A22 provided on the front surface of the housing A. A second air duct A5 connecting the air inlet A1 and the second air outlet A22 is defined in the housing A. The second air duct A5 extends in the vertical direction. That is, the air from the air inlet A1 can flow along the second air duct A5 and out of the second air outlet A22.

[0094] The blocking member H is arranged in the second air duct A5 to divide the second air duct A5 into a first sub-air duct A51 and a second sub-air duct A52 separated from each other on the left and right sides. A confluence area is formed on the leeward side of the blocking member H and the confluence area is connected to both 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 confluence area and then flows out of the second air outlet A22 in the direction of the blocking member H. In this way, when the air from the air inlet A1 flows along the second air duct A5, the blocking member H can divide the airflow into two parts, that is, one part flows along the first sub-air duct A51 and the other part flows along the second sub-air duct A52, and then after merging in the confluence area, flows out of the second air outlet A22 in the extension direction of the blocking member H.

[0095] It can be understood that the first sub-air duct A51, the second sub-air duct A52 and the confluence area formed between the blocking member H and the housing A guide the airflow of the second air duct A5 and discharge it toward the second air outlet A22. As a result, the airflow can flow in the first channel and the second channel, so that the airflow is effectively diverted and the air outlet is more uniform. That is, by setting the blocking member H in the second air duct A5 to form the first sub-air duct A51, the second sub-air duct A52 and the confluence area, the airflow of the second air duct A5 is effectively diverted, and the air outlet is more uniform, thereby improving the user experience.

[0096] In some embodiments, Figure 3 and 4 As shown, the blocking member H extends in a direction perpendicular to the air duct and toward the second air outlet A22. That is, the blocking member H can block the air flowing through the air duct, and introduce the airflow into the first sub-air duct A51 and the second sub-air duct A52. After the air flowing through the first sub-air duct A51 and the second sub-air duct A52 merges in the confluence area, the blocking member H is sent out in the direction in which the blocking member H extends toward the second air outlet A22. It should be noted here that the inner cavity of the blocking member H can be used to guide the airflow, and is also called a guide ring G when used for this function.

[0097] In some embodiments, Figure 3 As shown, the inner cavity of the blocking member H forms a first air duct A4, a first fan D is arranged in the first air duct A4, and a first air outlet A21 is formed at one end of the blocking member H facing the second air outlet A22, wherein the first air outlet A21 is located in front of the first sub-air duct A51, the second sub-air duct A52 and the confluence area. In this way, the air at the air inlet A1 sucked in by the first fan D can flow forward along the first air duct A4, and flow to the first air outlet A21 through the drainage of the inner cavity of the blocking member H. In this way, the air at the air inlet A1 can be drained by multiple channels, which is conducive to further increasing the range of air flow, thereby improving the air supply effect of the air conditioner indoor unit 1000.

[0098] Alternatively, if Figure 4As shown, in the left-right direction, the lower baffle plate H1 is located in the middle of the housing A. It also includes: a left baffle plate H31 and a right baffle plate H32. The left baffle plate H31 is connected to the left end of the lower baffle plate H1 and extends upward, and a first sub-air duct A51 is defined between the left baffle plate H31 and the inner wall of the housing A. The right baffle plate H32 is connected to the right end of the lower baffle plate H1 and extends upward, and a second sub-air duct A52 is defined between the right baffle plate H32 and the inner wall of the housing A. That is, after being guided by the lower baffle plate H1, the airflow will enter the first sub-air duct A51 defined between the left baffle plate H31 and the inner wall of the housing A, and the second sub-air duct A52 defined between the right baffle plate H32 and the inner wall of the housing A, and flow along the direction in which the left baffle plate H31 and the right baffle plate H32 extend upward.

[0099] Furthermore, if Figure 4 As shown, the cross-sections of the left blocking plate H31 and the right blocking plate H32 in the front-to-back direction are arc-shaped, and the opposite sides of the left blocking plate H31 and the right blocking plate H32 are respectively concave. In this way, the arcs concave on the opposite sides of the left blocking plate H31 and the right blocking plate H32 can guide the airflow from the lower blocking plate H1, and the arc setting will be conducive to the rapid diversion of wind and increase the amount of incoming wind.

[0100] In some optional embodiments, such as Figure 4 As shown, the left blocking plate H31 and the right blocking plate H32 are respectively transitioned with the lower blocking plate H1 in an arc shape, so as to facilitate the rapid passage of airflow and reduce the energy loss of airflow.

[0101] In some optional embodiments, such as Figure 4 As shown, the blocking member H also includes: an upper blocking plate H2, the two ends of which are respectively connected to the left blocking plate H31 and the right blocking plate H32, wherein the lower blocking plate H1, the left blocking plate H31, the right blocking plate H32 and the upper blocking plate H2 jointly define a first air duct A4 that runs through the front-to-back direction. On the one hand, the upper blocking plate H2, the lower blocking plate H1, the left blocking plate H31 and the right blocking plate H32 jointly define a first air duct A4 that runs through the front-to-back direction, so that the airflow can flow along the first air duct A4. On the other hand, the upper blocking plate H2, the lower blocking plate H1, the left blocking plate H31 and the right blocking plate H32 can also jointly define a second air duct A5 that runs through the upper and lower parts with the air outlet frame F.

[0102] Specifically, Figure 4 As shown, the cross section of the upper blocking plate H2 in the front-to-back direction is arc-shaped and protrudes upward, and there is an arc transition between the upper blocking plate H2 and the left blocking plate H31 and the right blocking plate H32 to facilitate the rapid passage of airflow and reduce energy loss of airflow.

[0103] In some embodiments, Figure 8 and Fig. 9 As shown, the air conditioner indoor unit 1000 further includes a first air guide assembly J11, which is disposed between the housing A and the blocking member H. Each first air guide assembly J11 includes a plurality of longitudinal guide vanes 130 extending in the up-down direction, and the plurality of longitudinal guide vanes 130 are disposed in the left-right direction, wherein the lengths of the plurality of longitudinal guide vanes 130 gradually decrease 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 left-right direction, so as to further adjust the flow direction of the airflow and make the air discharge more uniform.

[0104] In some embodiments, Figure 8 and Fig. 9 As shown, the second air guide assembly J12 is also included. The second air guide assembly J12 is arranged in the housing A and is located in front of the first air guide assembly J11. The second air guide assembly J12 includes a plurality of transverse guide vanes 110 extending in the left-right direction. The plurality of transverse guide vanes 110 are arranged in the up-down direction. In this way, the transverse guide vanes 110 can be used to guide the airflow sent out from the front air outlet A2 in the up-down direction to further adjust the flow direction of the airflow and make the airflow more uniform.

[0105] In some embodiments, Figure 7 As shown, the air conditioner indoor unit 1000 further includes an air guide cover N, which is arranged at the front end of the blocking member H and is configured to guide the airflow passing through it to be spirally sent out. 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 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 volume of the first air outlet A21, and at the same time, the air outlet air volume and air supply range of the air conditioner indoor unit 1000 can be increased.

[0106] Reference below Figure 1-Figure 24 , an air conditioner indoor unit 1000 according to an embodiment of the present invention is described in detail.

[0107] In some embodiments, Figure 1 and Figure 7 As shown, it includes: a housing A, a first air outlet A21, a second air outlet A22 and an air outlet mesh cover L. The housing A includes a main body A6 and a front panel A8. An air inlet A1 is formed on the housing A. The second air outlet A22 is arranged around the first air outlet A21. 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 to the front air outlet A2.

[0108] The air outlet mesh cover L is set at the front end of the first air outlet A21 and the second air outlet A22, and is connected to the front air outlet A2. It can be understood that the air outlet of the existing air conditioner is open, resulting in the internal structure of the air conditioner being exposed to the outside, and the appearance is relatively simple and unsightly. In this solution, the air outlet mesh cover L is set at the front end of the first air outlet A21 and the second air outlet A22.

[0109] The cover L can protect the structure inside the air conditioner, which is safer and can make the wind flow more even, thereby enhancing the wind 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.

[0110] It should be noted that the air after heat exchange in the air conditioner can be sent out in two parts, one of which reaches the first air outlet A21 and is sent out, and after encountering the air outlet mesh cover L, the flow rate is slowed down and the air is sent out evenly; the other part of the air passes through the second air outlet A22 and the air outlet mesh cover L and is sent out, thereby increasing the air outlet range of the air conditioner and improving the regulating effect on the indoor air. That is, by arranging the air outlet mesh cover L at the front end of the first air outlet A21 and the second air outlet A22, the structure of the air conditioner indoor unit 1000 is diversified, and the air outlet effect can be further enhanced, thereby improving the user experience.

[0111] In some embodiments, Figure 1 and Figure 3 As shown, the front end of the main body A6 has an open opening A7, and the front panel A8 is arranged at the front end of the main body A6 and covers at least a part of the open opening A7. In this way, the air after heat exchange in the air conditioner can also be sent out through the uncovered open opening A7. Specifically, in addition to the front air outlet A2 on the front panel A8 on the entire shell, the uncovered open opening A7 on the main body A6 is also equivalent to another air outlet, so that the shell 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.

[0112] Specifically, Figure 2 and Figure 3 As shown, the housing A is also provided with a third air outlet A3, which is located above the front air outlet A2 and blows air forward. Figure 2 and Figure 3The arrow in the figure indicates the direction of wind flow. That is to say, the third air outlet A3 and the front air outlet A2 together 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 blow air outward from the front air outlet A2 of the front panel A8, and can also blow air upward from the third air outlet A3 on the top of the air conditioner, thereby further improving the air outlet effect. It should be noted that the front side referred to here in the present invention refers to the side of the air conditioner facing the user. The third air outlet A3 mentioned above can be defined by the uncovered open opening A7 portion on the main body A6.

[0113] In some embodiments, Figure 3 and Figure 4 As shown, the first air outlet A21 is connected with the air inlet A1, and a first fan D is arranged in the first air duct A4 formed by the connection; the second air outlet A22 is connected with the air inlet A1, and a second fan E is arranged in the second air duct A5 formed by the connection; the first fan D and the second fan E are controlled independently. In this way, the first fan D is used to drive the 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 the air to flow from the air inlet A1 to the front air outlet A2 or the above-mentioned uncovered open opening A7.

[0114] In some embodiments, Figure 5 As shown, there is a predetermined gap A71 between the upper edge of the front panel A8 and the upper edge of the open opening A7. That is to say, 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, and the third air outlet A3 and the front air outlet A2 located below it jointly supply air, and when the air conditioner blows air outward, it can blow air outward from the front air outlet A2 of the front panel A8, and can also 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 further enhancing the air outlet effect. It should be noted that the front side referred to here in the present invention refers to the side of the air conditioner facing the user.

[0115] Specifically, the lower edge of the front panel A8 can be attached to the lower edge of the opening A7, the left edge of the front panel A8 can be attached to the left edge of the opening A7, and the right edge of the front panel A8 can be attached to the right edge of the opening A7. Thus, the above-mentioned edges cover each other to ensure that there is no gap between them, that is, to ensure that the air after heat exchange in the air conditioner can only be sent out from the front air outlet A2 and the third air outlet A3.

[0116] Furthermore, if Figure 5As shown, in the main view of the housing A, the range of the predetermined gap A71 can be 40mm to 150mm. It is understandable that if the predetermined gap A71 is too small, it is not conducive to the rapid delivery of the air after heat exchange in the air conditioner, and it is easy to cause the wind to accumulate in the housing, increase the internal pressure, and have a problem of poor heat dissipation effect; and if the predetermined gap A71 is too large, the air after heat exchange is delivered from another air outlet in an instant, resulting in uneven flow of the wind, which is not conducive to the circulation of wind in the room. Therefore, setting the range of the predetermined gap A71 to 40mm to 150mm can ensure that within this area, the effect of the wind flowing through the predetermined gap A71 is better.

[0117] In a specific embodiment, the size of the predetermined gap A71 can be 40 mm. 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 relatively large. In this state, the air after heat exchange by the air conditioner is mainly delivered from the front air outlet A2, supplemented by the top air outlet formed by the predetermined gap A71, thereby improving the air outlet effect of the air conditioner.

[0118] In a specific embodiment, the size of the predetermined gap A71 may be 66 mm. It can be understood that this can not only ensure a better effect of delivering the air inside the air conditioner, but also ensure the circulation of the air indoors. At this time, the predetermined gap A71 has the best air outlet effect.

[0119] In a specific embodiment, the size of the predetermined gap A71 can also be 150 mm. It can be understood that at this time, the size difference between the top air outlet formed by the predetermined gap A71 and the front air outlet A2 on the front panel A8 is the smallest. In this state, the wind after heat exchange by the air conditioner is mainly from the two air outlets. The functions of the two are basically the same, and they jointly play a role in adjusting the outward wind effect of the air conditioner.

[0120] In some embodiments, Figure 1-Figure 5 As shown, the height range of the front panel A8 can be 1300mm to 1800mm. Thus, the height of the front air outlet A2 is suitable for the height of the human body, and the wind sent out by the front air outlet A2 can be directly blown to the area where the human body is located. At the same time, combined with the above-mentioned third air outlet A3 structure, it can be known that the height of the third air outlet A3 is higher than the area where the human body is located. At this time, the wind sent out by the third air outlet A3 blows 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 user's comfort.

[0121] The ratio between the height of the front panel A8 and the height of the air outlet grille L is in the range of 2 to 5, and the ratio between the area of ​​the front panel A8 and the area of ​​the air outlet grille L is in the range of 3 to 6. The following are optional embodiments:

[0122] Optionally, in some specific embodiments, the height of the front panel A820 can be 1300 mm. At this time, the height of the front panel A820 is the smallest, and the height of the relative air outlet 21 is relatively small, and the air conditioning air is relatively concentrated at a relatively low height in the room.

[0123] In a specific embodiment, the height of the front panel A820 can also be 1800 mm. At this time, the height of the front panel A820 is the largest, and the height of the air outlet 21 is relatively large, and the air outlet of the air conditioner is relatively concentrated at a higher height in the room.

[0124] In a specific embodiment, the ratio between the height of the front panel A8 and the height of the air outlet grille L may be 3.75, and the ratio between the area of ​​the front panel A8 and the area of ​​the air outlet grille L may be 4.5, which is more conducive to production.

[0125] In a specific embodiment, the height of the front panel A8 is 1582 mm, and the height of the main body A6 is 1879 mm. In this case, the ratio of the heights of the two is appropriate, and the appearance is more beautiful.

[0126] In a specific embodiment, the distance between the bottom of the air outlet mesh cover L and the bottom of the main body A6 is 1234 mm, and the position of the front air outlet A2 can also be determined by the position of the air outlet mesh cover L. In this way, the height position of the air outlet mesh cover L and the front air outlet A2 is most suitable, which is conducive to the air conditioner to blow outward. In addition, when the air outlet mesh cover L is at this height position, the air conditioner can avoid direct blowing on children when blowing outward, preventing children from catching a cold or other diseases due to direct blowing in the cold wind state.

[0127] In some embodiments, Figure 5 As shown, the size range of the air outlet grille L in the left and right direction can be: 350mm~450mm. The air outlet grille L is connected to the front air outlet A2. When the size of the air outlet grille L is too small, it will hinder the air outlet capacity of the front air outlet A2. Considering the actual size of the air conditioner, the size of the air outlet grille L within this size range is more suitable. Similarly, the air outlet grille L under this size is easy to make and is conducive to production.

[0128] In a specific embodiment, the size of the air outlet grille L in the left and right directions may be 350 mm. At this time, the size of the air outlet grille L is the smallest, and the air outlet capacity of the front air outlet A2 is subject to certain restrictions to achieve a stable air outlet effect of the front air outlet A2.

[0129] In a specific embodiment, the size of the air outlet grille L in the left-right direction may be 382 mm, so that the size of the air outlet grille L is appropriate and the air supply effect is good.

[0130] In a specific embodiment, the size of the air outlet grille L in the left and right directions can also be 450 mm. At this time, the size of the air outlet grille L is the largest, and the flow rate of air blowing outward from the front air outlet A2 is the largest, which helps to further expand the air outlet range of the air conditioner.

[0131] More specifically, if Figure 5 As shown, when the size of the air outlet grille L in the left-right direction is 382 mm, the size of the air outlet grille L in the up-down direction is 392 mm. Therefore, the air outlet grille L can completely cover the front air outlet A2 in the area under this size.

[0132] In some optional embodiments, such as Figure 6 As shown, the air outlet mesh cover L is provided with a plurality of evenly arranged equilateral triangle meshes L1, and the side length of each mesh L1 ranges from 1mm to 20mm. Therefore, making the mesh L1 into an equilateral triangle shape can play a better decorative role and make the overall appearance more beautiful. Secondly, if the mesh L1 is too small, it is not conducive to the delivery of wind, and if the mesh L1 is too large, it will not have a certain wind resistance effect. Therefore, the side length range of the mesh L1 is set to 1mm to 20mm, which is not only conducive to the delivery of wind, but also can play a certain wind resistance role and improve the wind outlet effect.

[0133] In a specific embodiment, the side length of the equilateral triangle mesh L1 on the air outlet grille L can be 1 mm. That is to say, the mesh L1 on the air outlet grille L is the smallest and densest, making it difficult to observe the internal structure of the air conditioner, and has a more decorative effect in appearance and is more beautiful.

[0134] In a specific embodiment, the side length of the equilateral triangle mesh L1 on the air outlet grille L can also be 20 mm. That is to say, at this time, the mesh holes L1 on the air outlet grille L are the largest and loose, which is conducive to the air outlet of the air conditioner.

[0135] In a specific embodiment, the side length of the plurality of meshes L1 may be 13.5 mm, which is beneficial to production and manufacturing and reduces costs.

[0136] In other embodiments, the shape of the mesh L1 is not limited to an equilateral triangle, but can also be set to other shapes. For example, the mesh L1 can also be a rhombus, rectangle, circle or ellipse (not shown in the figure). Similarly, when the mesh L1 is a rhombus, the side length of the rhombus can be 13.5 mm, thereby ensuring that the mesh L1 has a good ventilation effect.

[0137] Of course, in other embodiments of the present invention, the shape of the mesh L1 can be diverse, and can be a combination of multiple graphics. For example, the air outlet mesh cover L can be composed of multiple concentric circle areas (not shown in the figure), the mesh L1 in the middle concentric circle area is in the shape of an equilateral triangle, the mesh L1 in the outer concentric circle area is a rhombus, and the mesh L1 in the outer concentric circle area is in the direction, so that the overall appearance is more beautiful. For another example, the air outlet mesh cover L can be composed of multiple square ring areas (not shown in the figure), the mesh L1 in the innermost square ring area is a rhombus, the mesh L1 in the outer square ring area is a square, and the mesh L1 in the outermost square ring area is an equilateral triangle, which can also improve the aesthetics.

[0138] In some optional embodiments, such as Figure 6 As shown, the ratio of the sum of the areas of the plurality of meshes L1 to the area of ​​the air outlet is in the range of 0.5 to 0.8. In this way, that is to say, the air outlet mesh cover L as a whole can play a certain wind resistance effect, and the air after heat exchange in the air conditioner indoor unit 1000 is sent out from the front air outlet A2, and first acts on the air outlet mesh cover L, and diffuses and blows out from the mesh L1 after being blocked to a certain extent, thereby avoiding the concentrated outward blowing of the air after heat exchange, and a part of the air conditioning wind will still directly pass through the mesh L1 and blow out after acting on the air outlet mesh cover L, but at this time, the wind feeling of the human body has been weakened to a certain extent, with a more suitable comfort, and another part of the wind will diffuse along the circumference of the air outlet mesh cover L and blow out from the nearest mesh L1, so that the meshes L1 at other positions on the air outlet mesh cover L are all winded, and the effect of blowing air evenly is achieved, thereby improving the wind feeling of the air conditioner blowing air.

[0139] In some embodiments, Figure 1 As shown, the front surface of the front panel A8 is an arc-shaped surface, and the left edge and the right edge of the front panel A8 extend backward, and the bending radius of the left edge and the right edge of the front panel A8 ranges from 30mm to 80mm. In this way, the front surface of the front panel A8 is made into an arc-shaped surface, so that the front panel A8 has a certain depth in the front and rear directions, and can play a certain wrapping role when matched with the front end surface of the main body A6, making the interior of the casing A more compact, and the combination of the two is better and easier to manufacture. Secondly, the design of the front panel A8 with an arc surface is more excellent, avoiding sharp edges on the left and right edges of the casing A, which can reduce damage to the human body during transportation and is safer. In addition, the structural design of the arc surface is more aesthetically pleasing, more beautiful in appearance, and makes the exterior of the air conditioner feel better when touched.

[0140] In a specific embodiment, the bending radius of the left and right edges 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 and right edges of the front panel A8, which is more conducive to the front panel A8 being combined with the main body A6.

[0141] Of course, in the specific example, the bending radius of the left edge and the right edge of the front panel A8 can be 30 mm. In this case, the front panel A8 is more convenient to manufacture, which can reduce the manufacturing difficulty and save the manufacturing cost.

[0142] In addition, in other examples, the bending radius of the left and right edges of the front panel A8 can also be 80 mm. In this case, the depth of the front panel A8 combined with the main body A6 is deeper, which makes the combination of the two more secure.

[0143] In other embodiments, the dimension of the front panel A8 in the front-to-back direction ranges from 60 mm to 100 mm. Specifically, the dimension of the front panel A8 in the front-to-back direction is 70 mm. It can be understood that 70 mm is the optimal dimension of the front panel A8 in the front-to-back direction at this time, and it can also be understood that the depth of the front panel A8 in the front-to-back direction is 70 mm, which is conducive to the front panel A8 being closely attached to and wrapped on the main body A6 to achieve the combination of the two.

[0144] In other embodiments, the thickness of the middle portion of the body A6 in the front-to-back direction is 118 mm, and the thickness of the upper and lower ends of the body A6 in the front-to-back direction is 207 mm. It can be understood that the value at this time is the optimal size of the body A6 in the front-to-back direction, but it is not limited to this. With this size design, the housing A is thinner as a whole, with a stronger three-dimensional sense, making the internal structure more compact and smaller in size, and will not occupy too much space, making it easier to place.

[0145] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the air conditioner indoor unit 1000 further includes a guide ring G with a circular cross section in the front-to-back direction, a first air duct A4 is defined in the guide ring G, and a second air duct A5 is defined between the outer wall of the guide ring G and the inner wall of the housing A. It can be understood that a portion of the air sent from the air inlet A1 can be guided through the second air outlet A22 to enter the indoor conditioned air.

[0146] Furthermore, if Figure 4 and Figure 7As shown, the air conditioner indoor unit 1000 further includes an air outlet frame F having a rectangular cross section in the front-to-back direction, the air outlet frame F is arranged in the housing 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 sent from the air inlet A1 can be guided by the guide ring G, and the air can flow in the first air duct A4. In this way, the air at the air inlet A1 can be guided in a variety of ways, thereby increasing the range of air flow, thereby improving the air supply effect of the air conditioner indoor unit 1000.

[0147] Part of the air entering from the air inlet A1 can be guided by the first air duct A4 and enter the room from the first air outlet A21. Another part of the air sent from the air inlet A1 can be guided between the air outlet frame F and the guide ring G and enter the room from the second air outlet A22. In this way, the air at the air inlet A1 can be guided in a variety of ways to increase the range of air flow, thereby improving the air supply effect of the air guide mechanism J.

[0148] The first fan D and the second fan E are controlled independently, that is, the control of the first fan D and the second fan E are independent of each other and are not affected by each other. Specifically, the first fan D and the second fan E can work at the same time or one of them can guide the air. The rotation speeds 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-conditioning indoor unit 1000 and improving the air supply effect.

[0149] Specifically, the first fan D may be an axial flow fan or a cross flow fan, and the second fan E may be a centrifugal fan or a cross flow fan, thereby making the structures of the first fan D and the second fan E more diverse and achieving better air supply effects.

[0150] It should be noted that the first fan D is not limited to the above-mentioned axial flow 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 flow fan or a diagonal flow fan, etc.

[0151] In some embodiments, the air conditioner indoor unit 1000 includes an air guide assembly J1, which includes a longitudinal guide vane 130 and a transverse guide vane 110. The longitudinal guide vane 130 is provided at the first air outlet A21 and is used to guide air in the left and right directions. In this way, the air at the second air outlet A22 can be guided by the longitudinal guide vane 130, thereby sending the air into the room.

[0152] The transverse guide vane 110 is disposed in front of the longitudinal guide vane 130 and is used to guide air in the up and down directions. In this way, the transverse guide vane 110 can be used to simultaneously guide the air sent out from the first air outlet A21 and the second air outlet A22, thereby expanding the range of air flow guidance and reducing the space occupied by the air guide assembly J1, thereby improving the air supply effect of the air guide assembly J1 and enhancing the user experience.

[0153] In some embodiments, Figure 3 and Fig.24 As shown, a heat exchanger B is provided in the casing A, and the heat exchanger B is provided at the rear side of the main body A6. An air inlet mesh cover M is provided at the rear side of the heat exchanger B, and the air inlet mesh cover M is matched 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, and forms wind after heat exchange in the heat exchanger B. One part of the air flows outward from the front air outlet A2 of the front panel A8 and the air outlet mesh cover L, and the other part is blown 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.

[0154] Alternatively, if Figure 5 As shown, the top of the opening A7 is provided with a chamfer A61, which can reduce sharp changes, improve safety, and play a certain wind-guiding effect. For example, when the air conditioner indoor unit 1000 blows air outward through the opening A7, the wind has a high velocity and low pressure at this position when passing through the chamfer A61, and the wind at this position will be blown outward along the chamfer A61, so that the wind passing through the opening A7 is blown outward in a trumpet shape, thereby expanding the blowing range and avoiding wind concentration, which can also improve the blowing comfort.

[0155] Reference below Figure 8-Figure 14 The air guide mechanism J according to an embodiment of the present invention is described. As shown in the accompanying drawings, the air guide mechanism J includes: a guide ring G, a first fan D, a second air outlet A22 and at least one guide blade 100. 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 used to drive the air to flow out of the first air inlet A1 and out of the first air outlet A21; the second air outlet A22 is arranged around the first air outlet A21; and is used to guide the air flowing out of the first air outlet A21, and at the same time guide the air flowing out of the second air outlet A22. That is, by at least one guide blade 100, which is used to simultaneously guide the air flowing out of the first air outlet A21 and the second air outlet A22, the range of air diversion can be expanded, and the space occupied by the air guide mechanism J can be reduced, thereby improving the air supply effect of the air guide mechanism J and enhancing the user experience.

[0156] In some embodiments, Figure 8 and Fig. 9As shown, the air guide mechanism J of the air conditioner indoor unit 1000 also includes: an air outlet frame F. The air outlet frame F includes a rear plate F1, and a vent hole F4 is provided on the rear plate F1. The guide ring G is arranged in the air outlet frame F, and the axis of the guide ring G is arranged perpendicular to the vent hole F4, wherein the guide ring G defines a first air duct A4 that runs through its length along its axial direction, the first air duct A4 is connected to 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 a part of the air sent from the air inlet A1 can flow forward through the vent hole F4, pass through the drainage of the first air duct A4, and enter the room from the first air outlet A21. Another part of the air sent from the air inlet A1 can be drained through the position between the air outlet frame F and the guide ring G, and enter the room from the second air outlet A22. In this way, the air at the air inlet A1 can be guided in a variety of ways, thereby increasing the range of air flow and improving the air supply effect of the air guide mechanism J.

[0157] In some embodiments, Figure 8 As shown, the air guide blade 100 includes: a plurality of transverse guide vanes 110. The plurality of transverse guide vanes 110 are rotatably arranged in the air outlet frame F and are located at the front side of the guide ring G. The plurality of transverse guide vanes 110 are arranged spaced apart in the up-down direction. At least a portion of the plurality of transverse guide vanes 110 is provided with a groove 1101 for accommodating the guide ring G. The portions of the transverse guide vanes 110 located on both sides of the groove 1101 extend backward to the rear side of the front end of the guide ring G. It can be understood that the arrangement of the groove 1101 can make the portions of the transverse guide vanes 110 located on both sides of the groove 1101 extend backward to the rear side of the front end of the guide ring G. In this way, the distance between the transverse guide vanes 110 and the first fan D is shortened, so that the air volume of the air supply is increased, and the air supply range of the transverse guide vanes 110 can be expanded, thereby improving the air supply effect of the transverse guide vanes 110.

[0158] Specifically, Figure 8-Figure 12 As shown, the air guide mechanism J also includes: a connecting rod 120 and a driving device 160. The connecting rod 120 extends in the up-down direction, and each transverse guide vane 110 is connected to the connecting rod 120. The driving device 160 is connected to the connecting rod 120 or the transverse guide vane 110 to drive the transverse guide vane 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 guide vane 110 connected to the connecting rod 120 rotates together with the connecting rod 120; the driving device 160 can also drive at least one of the transverse guide vanes 110, so that the connecting rod 120 connected to the transverse guide vane 110 moves together with the transverse guide vane 110, and then the other transverse guide vanes 110 connected to the connecting rod 120 will rotate together with the connecting rod 120, and then the rotating transverse guide vanes 110 can guide the flow direction of the air of the first air outlet A21 and the second air outlet A22.

[0159] Furthermore, if Fig. 9 As shown, the air outlet frame F also includes a left side plate F2 and a right side plate F3, the left side plate F2 is arranged on the left side of the rear plate F1 and extends forward, the right side plate F3 is arranged on the right side of the rear plate F1 and extends forward, and the two ends of each transverse guide vane 110 are rotatably connected to the left side plate F2 and the right side plate F3, respectively, and the driving device 160 is arranged on the left side plate F2 or the right side plate F3 and is transmission-connected with at least one of the transverse guide vanes 110. In this way, the driving device 160 can drive the transverse guide vane 110 to make the transverse guide vane 110 relatively rotate on the left side plate F2 and the right side plate F3, so that the connecting rod 120 connected to the transverse guide vane 110 moves with the transverse guide vane 110, and then the other transverse guide vanes 110 connected to the connecting rod 120 will rotate with the connecting rod 120, and then the rotating transverse guide vane 110 can guide the flow direction of the air of the first air outlet A21 and the second air outlet A22.

[0160] In some optional embodiments, such as Figure 9-11 As shown, the connecting rod 120 is provided with a plurality of hooks 1201, and the plurality of transverse guide vanes 110 are respectively connected with the plurality of hooks 1201 in a one-to-one correspondence, wherein the transverse guide vane 110 is provided with a hanging column 1103, and the hanging column 1103 is matched with the hook 1201. That is, through the cooperation between the hanging column 1103 and the hook 1201, the connecting rod 120 is connected with the transverse guide vane 110, and under the action of the friction force between the hanging column 1103 and the hook 1201, the connecting rod 120 and the transverse guide vane 110 can move together.

[0161] Specifically, Fig.13 As shown, the transverse guide vane 110 is provided with a mounting groove 1102 that is open to the rear, and the mounting post 1103 is provided in the mounting groove 1102, wherein the hook 1201 hooks the mounting post 1103 from top to bottom or from bottom to top, and the mounting posts 1103 on each transverse guide vane 110 correspond in the up-down direction. In this way, the hook 1201 can hook the mounting post 1103 from top to bottom or from bottom to top, so that the transverse guide vane 110 is connected to the connecting rod 120. Since the transverse guide vane 110 is installed 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 to the transverse guide vane 110 can be stably installed on the transverse guide vane 110.

[0162] Furthermore, if Fig.12As shown, each hook 1201 includes a transverse extension portion 1201A and a longitudinal extension portion 1201B, the transverse extension portion 1201A and the longitudinal extension portion 1201B are vertically connected to each other, and the transverse extension portion 1201A is connected to the connecting rod 120. The cross section of the transverse extension portion 1201A is semicircular. It can be understood that the transverse extension portion 1201A can provide a matching surface for the mounting column 1103. After assembly, there is a certain friction between the transverse extension portion 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 multiple transverse guide vanes 110, the friction between the mounting column 1103 and the arc surface on the transverse guide vane 110 can drive the connecting rod 120 to rotate together, thereby driving the other transverse guide vanes 110 on the hook 1201 to rotate relatively together. When the driving device 160 directly drives the connecting rod 120 , the friction force between the mounting column 1103 and the lateral extension portion 1201A will directly drive the lateral guide vane 110 to rotate along with the connecting rod 120 , thereby achieving wind guiding.

[0163] The mounting column 1103 in this embodiment can pass through the longitudinal extension portion 1201B to fit with the outer surface of the transverse extension portion 1201A, thereby eliminating the need to assemble the transverse guide vane 110 on the hook 1201 by extrusion. This can minimize the deformation of the hook 1201, thereby increasing the structural strength of the hook 1201 and improving the assembly efficiency of the transverse guide vane 110 and the hook 1201.

[0164] Alternatively, if Fig.10 As shown, one end of the two ends of the length of the connecting rod 120 is provided with a hook 1201, and the other end of the two ends of the length of the connecting rod 120 is provided with a transverse stopper 1202 perpendicular to the length of the connecting rod 120. It can be understood that the hook 1201 provided at one end of the two ends of the length of the connecting rod 120 can be installed with the transverse guide vane 110. In this way, when the transverse guide vane 110 is installed on the hook 1201, the transverse stopper 1202 provided at the other end of the two ends of the length of the connecting rod 120 and perpendicular to the length of the connecting rod 120 can provide a stop position for clamping, thereby facilitating the installation of the transverse guide vane 110.

[0165] In some optional embodiments, such as Fig.13As shown, on the transverse guide vane 110 provided with a groove 1101, an installation groove 1102 is formed on the bottom wall of the groove 1101 and is recessed forward, and the transverse guide vane 110 located at the bottom of the plurality of transverse guide vanes 110 is arranged below the lowest end of the guide ring G, and in the transverse guide vane 110 located at the bottom, the installation groove 1102 is formed at the rear end of the transverse guide vane 110 and is recessed forward. It can be understood that the transverse guide vane 110 provided with the groove 1101 can make part of the transverse guide vane 110 extend backward to the rear side of the front end of the guide ring G. In this way, the distance between the transverse guide vane 110 and the axial flow fan is shortened, thereby increasing the air volume of the air supply, and can expand the air supply range of the air guide blade 100, thereby improving the air supply effect of the air guide blade 100. The transverse guide vane 110 located at the bottom is arranged below the lowest end of the guide ring G, and can be used to guide the air sent by the second air duct A5, and then discharged to the outside through the second air outlet A22.

[0166] In some optional embodiments, such as Figure 8 and Fig.13 As shown, in the front view of the transverse guide vane 110, the front end of the transverse guide vane 110 is arc-shaped, the rear end of the transverse guide vane 110 is linear, and the groove 1101 is formed in the middle of the rear end of the transverse guide vane 110, wherein the length of the grooves 1101 of the plurality of transverse guide vanes 110 gradually decreases in the direction from the center of the guide ring G to the upper and lower sides. The front end of the transverse guide vane 110 in this embodiment is arc-shaped, and the rear end of the transverse guide vane 110 is linear. This reduces the space required for the transverse guide vane 110 to rotate, which is conducive to the miniaturization of the air guide mechanism J. The length of the groove 1101 in the middle of the rear end of the transverse guide vane 110 gradually decreases in the radial direction of the guide ring G from the middle to the upper and lower sides. It can be understood that the lateral dimension of the guide ring G gradually decreases from the center to the upper and lower sides, and the part of the lateral guide vane 110 provided with the groove 1101 is arranged to extend backward to the rear side of the front end of the guide ring G. In this way, the length of the groove 1101 gradually decreases from the center of the guide ring G to the upper and lower sides, which is conducive to matching with the guide ring G.

[0167] Optionally, the vertical distance between the side wall of the groove 1101 and the outer wall of the guide ring G is in the range of 5 mm to 20 mm. In this way, a suitable distance is left between the side wall of the groove 1101 and the outer wall of the guide ring G, so that the transverse guide vane 110 does not contact the guide ring G during the rotation process, thereby ensuring the rigidity of the transverse guide vane 110.

[0168] Furthermore, the length of the groove 1101 ranges from 100 mm to 350 mm, and the depth of the groove 1101 ranges from 20 mm to 30 mm. In this way, the rear ends of each transverse guide vane 110 correspond in the up-down direction, and the portion of the transverse guide vane 110 extends backward to a suitable distance from the rear side of the front end of the guide ring G, thereby shortening the distance from the transverse guide vane 110 to the first fan D without affecting the normal operation of the first fan D, increasing the air volume, and expanding the air supply range of the transverse guide vane 110.

[0169] In some embodiments, Figure 8 and Fig. 9 As shown, the air guide blade 100 also includes: a longitudinal guide vane 130. The longitudinal guide 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 another example, air is exported from the second air outlet A22, or air is exported from the third air outlet A3. No matter 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 guide vane 130 described later.

[0170] The longitudinal guide vane 130 includes at least two first guide vanes 1301 and a plurality of second guide vanes 1302, and the first guide vanes 1301 and the second guide vanes 1302 are linked. That is, when the first guide vane 1301 moves, the second guide vane 1302 also moves, and the first guide vane 1301 and the second guide vane 1302 move and stop at the same time.

[0171] The length of the first air guide blade 1301 is greater than that of the second air guide blade 1302. The plurality of first air guide blades 1301 are pivotally arranged on the air outlet frame F, and the plurality of second air guide blades 1302 are pivotally arranged between the guide ring G and the air outlet frame F. That is, the first air guide blade 1301 is rotatable relative to the air outlet frame F, and the second air guide blade 1302 is rotatable relative to the air outlet frame F and the guide ring G.

[0172] The wind guide driving mechanism 150 drives the longitudinal guide vanes 130 to swing. The wind guide driving mechanism 150 controls the movement or stop of the longitudinal guide vanes 130.

[0173] It can be seen from the above structure that the first air guide blade 1301 can be pivotally set on the air outlet frame F, and the second air guide blade 1302 can be pivotally set on the guide ring G and the air outlet frame F, so that the air guide blade 100 has a stable rotation support point and a reliable connection. During the rotation process, the air guide blade 100 is not easy to separate from the air outlet frame F or the guide ring G, and the reliability is good. The air guide blade 100 can continuously and stably guide the air.

[0174] It can be understood that the first air guide blade 1301 is longer in length, and both ends thereof are connected to the air outlet frame F, while the second air guide blade 1302 is shorter in length, has a larger number, and is respectively connected to the guide ring G and the air outlet frame F. Compared with the first air guide blade 1301 which is all set to be longer in length, the present invention sets a plurality of shorter second air guide blades 1302, which greatly enhances the rigidity of the entire air guide blade 100 and reduces the resistance of the air outlet. In addition, compared with setting all the air guide blades 100 on the air outlet frame F, the second air guide blade 1302 of the present invention is set at one end on the air outlet frame F and at the other end on the guide ring G. The second air guide blade 1302 is easy to arrange and connect, and is not easy to deform or fall out after connection. In addition, the longitudinal guide vane 130 of the present invention does not need to be set on the air outlet side of the entire air outlet frame F, but can be selectively set in a local area of ​​the air outlet frame F, and the arrangement of the second air guide blade 1302 is more flexible.

[0175] Specifically, Fig. 9 As shown, the plurality of second air guide blades 1302 include a plurality of first group air guide blades 1302A and a plurality of second group air guide blades 1302B, the first group air guide blades 1302A are arranged above the guide ring G, and the second group air guide blades 1302B are arranged below the guide ring G. That is, the upper ends of the first group air guide blades 1302A located above the guide ring G are pivotally connected to the air outlet frame F, and the lower ends are pivotally connected to the guide ring G; the upper ends of the second group air guide blades 1302B located below the guide ring G are pivotally connected to the guide ring G, and the lower ends are pivotally connected to the air outlet frame F.

[0176] In some optional embodiments, such as Fig. 9 As shown, the longitudinal guide vane 130 also includes a wind sweeping connecting rod 170, and the wind guide driving mechanism 150 drives the wind sweeping connecting rod 170 to reciprocate, and the first wind guide blade 1301 and the second wind guide blade 1302 are respectively slidably connected to the wind sweeping connecting rod 170. The longitudinal guide vane 130 can be in a left-right wind sweeping state or an up-down wind sweeping state. When the longitudinal guide vane 130 is in a left-right wind sweeping state, the wind sweeping connecting rod 170 reciprocates left-right under the action of the wind guide driving mechanism 150; when the longitudinal guide vane 130 is in an up-down wind sweeping state, the wind sweeping connecting rod 170 reciprocates up-down under the action of the wind guide driving mechanism 150. When the longitudinal guide vane 130 is in an up-down wind sweeping state, the wind sweeping connecting rod 170 reciprocates up-down under the action of the wind guide driving mechanism 150. No specific restrictions are made here.

[0177] Specifically, Fig.14 and Fig.15As shown, the wind sweeping link 170 includes: an active wind sweeping link 1701 and a driven wind sweeping link 170, the active wind sweeping link 1701 is provided with a slide slot 1704, one end of the first wind guide blade 1301 is provided with a first guide rod 140 that slides with the slide slot 1704, the other end of the first wind guide blade 1301 is connected to the driven wind sweeping link 170, the end of the second wind guide blade 1302 close to the active wind sweeping link 1701 is provided with a second guide rod that slides with the slide slot 1704, and the end of the second wind guide blade 1302 close to the driven wind sweeping link 170 is connected to the driven wind sweeping link 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 the same motion state such as swing angle in addition to moving and stopping together.

[0178] In some optional embodiments, such as Fig. 9 and Fig.15 As shown, the active wind sweeping link 1701 and the driven wind sweeping link 170 are arranged in parallel, the wind guide driving mechanism 150 drives the active wind sweeping link 1701 to reciprocate, and the active wind sweeping link 1701 drives the driven wind sweeping link 170 to reciprocate through the first wind guide blade 1301. That is, when the wind guide driving mechanism 150 drives the active wind sweeping link 1701 to reciprocate left and right, the active wind sweeping link 1701 simultaneously drives the first wind guide blade 1301 and the first group of wind guide blades 1302A to move, the first wind guide blade 1301 on the active wind sweeping link 1701 transmits the force to the driven wind sweeping link 170 connected thereto, the driven wind sweeping link 170 follows the movement, and the driven wind sweeping link 170 further drives the second group of wind guide blades 1302B to move. Therefore, the first air guide blade 1301 and the second air guide blade 1302 of the present invention have high synchronization, the swing angle is accurately controlled, the air guide drive mechanism 150 is simply arranged, and occupies less layout space.

[0179] Specifically, Fig. 9 and Fig.15 As shown, when the active wind sweeping link 1701 reciprocates, the first guide rod 140 slides from one end of the slide slot 1704 to the other end, the first wind guide blade 1301 rotates 90 degrees, the second guide rod slides from one end of the slide slot 1704 to the other end, and the second wind guide blade 1302 rotates 90 degrees. Here, after the longitudinal guide vane 130 rotates 90 degrees, it can be switched to the first motion state and the second motion state respectively, so that the wind guide mechanism J has the first motion state and the second motion state, and the wind guide mechanism J can be switched between the first motion state and the second motion state.

[0180] Optional, such as Fig. 9 and Fig.15As shown, the slide groove 1704 is formed in a half-moon shape or an arc shape, and when the first guide rod 140 and the second guide rod slide in the slide groove 1704 smoothly, the guidance of the slide groove 1704 is convenient.

[0181] In some optional embodiments, such as Fig. 9 and Fig.15 As shown, the wind guide driving mechanism 150 includes a wind sweeping motor 1501 and a transmission gear 1502. The wind sweeping motor 1501 drives the transmission gear 1502 to rotate, and the active wind sweeping connecting rod 1701 is provided with a transmission tooth 1702 that cooperates with the transmission gear 1502. Therefore, when the wind sweeping motor 1501 rotates, the active wind sweeping connecting rod 1701 can be driven to reciprocate through the cooperation of the transmission gear 1502 and the transmission tooth 1702, and the driving is stable.

[0182] In some optional embodiments, such as Fig. 9 and Fig.15 As shown, the wind sweeping connecting rod 170 includes two active wind sweeping connecting rods 1701 arranged in parallel, the wind guide driving mechanism 150 includes two and drives the two active wind sweeping connecting rods 1701 to reciprocate respectively, the two ends of the first wind guide blade 1301 are slidably connected to the two active wind sweeping connecting rods 1701, and one end of the second wind guide blade 1302 is slidably connected to one of the active wind sweeping connecting rods 1701. That is, the first wind guide blade 1301 and the second wind guide blade 1302 are respectively driven by the active wind sweeping connecting rod 1701 and directly change the motion state. At this time, the driving transmission of the wind guide driving mechanism 150 should be kept synchronized as much as possible so that the motion states of all the first wind guide blades 1301 and all the second wind guide blades 1302 are consistent.

[0183] In some optional embodiments, such as Figure 8 and Fig. 9 As shown, the length of the second air guide blade 1302 increases in the direction away from the axis of the guide ring G. Therefore, the second air guide blade 1302 is more suitable for the space shape between the guide ring G and the air outlet frame F, so that the second air guide blade 1302 is easy to arrange and has a good movement effect after arrangement.

[0184] Alternatively, if Figure 8 and Fig. 9As shown, the longitudinal guide vane 130 has a first motion state and a second motion state, and the longitudinal guide vane 130 can be switched between the first motion state and the second motion state, wherein in the first motion state, the first guide vane 1301 and the second guide vane 1302 are parallel to the surface of the air outlet side of the guide ring G, and the gap between the first guide vane 1301 and the second guide vane 1302 is 1 to 2 mm; that is, the blade surface of the first guide vane 1301 and the second guide vane 1302 separates the guide ring G and the air outlet frame F along the air outlet direction, greatly reducing the amount or wind speed of the air discharged from the second air outlet A22. At this time, the first guide vane 1301 and the second 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 blade 1301 and the second air guide blade 1302 is greater than 2 mm, the two cannot form a side wall in the first motion state. When the gap between the first air guide blade 1301 and the second air guide blade 1302 is less than 1 mm, the two are prone to overlap or interfere and collide with other connecting parts in the first motion state.

[0185] In the second motion state, the first air guide blade 1301 and the second air guide blade 1302 are parallel to the extension direction of the guide ring G, the blade surfaces of the first air guide blade 1301 and the second air guide blade 1302 are opposite, and the distance between the blade surfaces of the first air guide blade 1301 and the second air guide blade 1302 is 4 to 6 mm. That is, the blade surfaces of the first air guide blade 1301 and the second air guide blade 1302 are parallel to the air outlet direction of the guide ring G, so that the wind in the second air outlet A22 can pass smoothly between the guide ring G and the air outlet frame F. If there is air outlet in the guide ring G, the air volume of the entire longitudinal guide blade 130 along the air outlet side of the guide ring G will be relatively large. In the second movement state, when the blade surface distance between the first air guide blade 1301 and the second air guide blade 1302 is less than 4 mm, the arranged air guide blades 10031 will be too dense, making it inconvenient to link and install; when the blade surface distance between the first air guide blade 1301 and the second air guide blade 1302 is greater than 6 mm, the air guide blades 100 are arranged too sparsely, resulting in poor flexibility when adjusting the air outlet.

[0186] Alternatively, if Figure 8 and Fig. 9 As shown, the longitudinal guide vane 130 has a first motion state and a second motion state, and the longitudinal guide vane 130 can be converted between the first motion state and the second motion state, wherein, in the first motion state, the projection area of ​​the first air guide blade 1301 and the second air guide blade 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 projection area of ​​the first air guide blade 1301 and the second air guide blade 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.

[0187] It is understandable that, in the first motion state, when the projection area of ​​the first air guide blade 1301 and the second air guide blade 1302 in the air outlet frame F accounts for less than 80% of the difference between the cross section of the air outlet frame F and the cross section of the guide ring G, the side wall effect formed by the first air guide blade 1301 and the second air guide blade 1302 in the first motion state will be weakened, and when the wind between the guide ring G and the air outlet frame F is designed to be an upper air outlet, the amount of wind directed upward is insufficient. When the projection area of ​​the first air guide blade 1301 and the second air guide blade 1302 in the air outlet frame F accounts for more than 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 first motion state, the first air guide blade 1301 and the second air guide blade 1302 are prone to overlap and interference.

[0188] In the second motion state, the projection area of ​​the first air guide blade 1301 and the second air guide blade 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. It can be understood that when the projection area of ​​the first air guide blade 1301 and the second air guide blade 1302 in the air outlet frame F accounts for less than 5% of the difference between the cross section of the air outlet frame F and the cross section of the guide ring G, the thickness of the first air guide blade 1301 and the second air guide blade 1302 will be too thin, the rigidity and strength are insufficient, and it is easy to deform. When the projection area of ​​the first air guide blade 1301 and the second air guide blade 1302 in the air outlet frame F accounts for more than 10% of the difference between the cross section of the air outlet frame F and the cross section of the guide ring G, the first air guide blade 1301 and the second air guide blade 1302 in the second motion state produce a large wind resistance to the wind between the guide ring G and the air outlet frame F, and the air outlet is not smooth enough.

[0189] Alternatively, if 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 arranged in the guide ring G. The air sucked in by the axial flow fan or the cross flow fan is guided along the guide ring G toward the first air outlet A21.

[0190] In some embodiments, Figure 16-18 As shown, the air conditioner indoor unit 1000 includes: a casing A, an air outlet frame F and a guide ring G.

[0191] An air inlet A1 and a front air outlet A2 are provided on the housing A. That is, the air entering through the air inlet A1 can flow out through the front air outlet A2.

[0192] The air outlet frame F is arranged in the housing A, and includes a left side plate F2 and a right side plate F3, which are arranged at intervals along the left-right direction, and the air outlet frame F is fixed in the housing A through the left side plate F2 and the right side plate F3. That is, on the one hand, the left side plate F2 and the right side plate F3 are arranged at intervals along the left-right direction to form a flow channel for airflow, which plays a role of guiding airflow. On the other hand, through the left side plate F2 and the right side plate F3, the air outlet frame F can be stably fixed on the housing A, which plays a role of limiting and fixing.

[0193] The guide ring G is arranged in the air outlet frame F, wherein a first sub-air duct A51 extending up and down is defined between the left side wall of the guide ring G and the left side plate F2, and a second sub-air duct A52 extending up and down is defined between the right side wall of the guide ring G and the right side plate F3. In this way, the air coming in from the air inlet A1 can flow through the inside of the guide ring G, and can also flow through the first sub-air duct A51 and the second sub-air duct A52 extending up and down formed by the left and right side plates F3 and the guide ring G, respectively. There are multiple branches for diversion, which is conducive to expanding the range of air supply and improving the effect of air supply. That is, the first sub-air duct A51 extending up and down is defined between the left side wall of the guide ring G and the left side plate F2, and the second sub-air duct A52 extending up and down is defined between the right side wall of the guide ring G and the right side plate F3, so that the left and right side plates F3 and the guide ring G form left and right branches flowing up and down, which is conducive to expanding the range of air supply, improving the effect of air supply, and enhancing the user experience.

[0194] In some embodiments, Fig.16 and Fig.17 As shown, the front air outlet A2 is located at the front side of the guide ring G, and the inner cavity of the guide ring G is connected with the air inlet A1 and the front air outlet A2 respectively to ensure that a part of the air delivered from the air inlet A1 can be guided by the inner cavity of the guide ring G and enter the front air outlet A2.

[0195] Specifically, Fig.16 and Fig.17 As shown, the air conditioner indoor unit 1000 further includes: a first fan D and a second fan E, the first fan D is arranged in the guide ring G to drive the airflow to flow from the air inlet A1 toward the front air outlet A2. The second fan E is arranged in the housing A, and in the length direction of the housing A, the third air outlet A3 and the second fan E are respectively located on opposite sides of the guide ring G to drive the airflow to flow from the air inlet A1 toward the front air outlet A2, and drive the airflow from the air inlet A1 to flow toward the third air outlet A3 after passing through the first sub-air duct A51 and the second sub-air duct A52.

[0196] It is understandable that the air sent from the air inlet A1 can be sucked in by the first fan D and discharged from the front air outlet A2. The air sent from the air inlet A1 can also be sucked in by the second fan E, and the airflow is driven to flow through the first sub-duct A51 and the second sub-duct A52 toward the front air outlet A2 and the third air outlet A3. In this way, the air at the air inlet A1 can be guided by multiple fans, increasing the range of air flow, thereby improving the air supply effect of the air conditioner indoor unit 1000.

[0197] In some embodiments, Figure 4 As shown, the first sub-duct A51 and the second sub-duct A52 are symmetrically arranged relative to the guide ring G, wherein the minimum width of the first sub-duct A51 and the second sub-duct A52 is W1, and W1 satisfies: 20mm≤W1≤60mm. It can be understood that the first sub-duct A51 and the second sub-duct A52 are symmetrically arranged relative to the guide ring G to serve as the circulation channel of the airflow driven by the second fan E. The width of the first sub-duct A51 and the second sub-duct A52 is too small, which is not conducive to the rapid delivery of the air after heat exchange in the air conditioner, and it is easy to cause the wind to accumulate in the shell, the internal pressure increases, and there are safety hazards. Therefore, the minimum width of the first sub-duct A51 and the second sub-duct A52 is set to 20mm≤W1≤60mm, which can ensure that within this area, the effect of the air flowing from the first sub-duct A51 and the second sub-duct A52 is better.

[0198] In some optional embodiments, such as Fig.17 As shown, a volute I is provided in the housing A, and a second fan E is provided 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 guide ring G. In this way, the second fan E can inhale the air from the air inlet A1 and flow into the volute I inlet I1, and the air flows toward the guide ring G after being sent out of the volute I outlet I2.

[0199] Specifically, Fig.17 As shown, the width of the air outlet end of the volute I is greater than the width of the guide ring G. That is, a part of the wind sent out of the outlet I2 of the volute I can pass through the obstruction of the guide ring G, so as to be divided and flow through the first sub-air duct A51 and the second sub-air duct A52, and because the width of the air outlet end of the volute I is greater than the width of the guide ring G, the wind sent out of the outlet I2 of the volute I 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.

[0200] In some embodiments, Figure 8 and Fig. 9As shown, the air conditioner indoor unit 1000 further includes a longitudinal guide vane 130, which is disposed between the housing A and the blocking member H. Each longitudinal guide vane 130 includes a plurality of longitudinal guide vanes 130 extending in the up-down direction, and the plurality of longitudinal guide vanes 130 are arranged side by side in the left-right direction, wherein the lengths of the plurality of longitudinal guide vanes 130 gradually decrease 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 left-right direction, so as to further adjust the flow direction of the airflow and make the air outlet more uniform.

[0201] Specifically, Figure 8 and Fig. 9 As shown, the air-conditioning indoor unit 1000 also includes a transverse guide vane 110, which is arranged in the casing A and is located in front of the longitudinal guide vane 130. The transverse guide vane 110 extends in the left-right direction and includes a plurality of transverse guide vanes 110. The plurality of transverse guide vanes 110 are arranged side by side in the up-down direction, so that the longitudinal guide vane 130 can be used to guide the airflow delivered from the front air outlet A2 in the up-down direction to further adjust the direction of the airflow and make the air outlet more uniform.

[0202] In some embodiments, the air conditioner indoor unit 1000 further includes: Figure 2 and Figure 3 As shown, the third air guide assembly J13. The third air guide assembly J13 includes a plurality of first air guide plates J131, which are rotatably arranged at the third air outlet A3 to open or close the third air outlet A3, and the rotation axis of the first air guide plate J131 extends along the width direction of the housing A. In this way, the first air guide plate J131 can rotate in the up and down directions, so that the air sent out of the third air outlet A3 can be guided by the plurality of first air guide plates J131 to adjust the wind direction, increase the range of air outlet, and make the air outlet more uniform. At the same time, when the first air guide plate J131 is closed, it also has a dustproof effect, which can protect the cleanliness of the inside of the air conditioner when it is not in operation.

[0203] Specifically, Figure 2 and Figure 3 As shown, the third air guide assembly J13 further includes a second air guide plate, which is rotatably disposed at the third air outlet A3, and is located upstream of the first air guide plate J131 along the flow direction of the airflow, and the rotation axis of the second air guide plate extends along the length direction of the housing A. In this way, the second air guide plate can rotate in the left-right direction, so that the air sent out of the third air outlet A3 can be guided by the first air guide plate J131 and the second air guide plate, further increasing the range of air outlet and enhancing the effect of air outlet.

[0204] In some embodiments, Figure 16-18 As shown, the air conditioner indoor unit 1000 includes: a casing A, a guide ring G and an axial flow fan wheel D1.

[0205] An air inlet A1 and a front air outlet A2 are formed on the housing A. A guide ring G is disposed in the housing A and defines a first air duct A4 for connecting the air inlet A1 and the front air outlet A2. The plane where the rear end of the guide ring G is located is the air guide surface G1. In this way, the air flowing in from the air inlet A1 can flow to the front air outlet A2 through the guidance of the guide ring.

[0206] The axial flow wind wheel D1 is rotatably arranged in the first air duct A4, and the rear end blade tip D12 of the axial flow wind wheel D1 extends backward beyond the wind guide surface G1. In this way, the distance between the axial flow wind wheel D1 and the air inlet A1 is shortened, the air suction range of the axial flow wind wheel D1 can be expanded, and the air volume sucked by the axial flow wind wheel D1 is increased, thereby improving the air supply effect of the air conditioner indoor unit 1000. 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 the rear end blade tip D12 of the axial flow wind wheel D1 extending backward beyond the wind guide surface G1, the distance between the axial flow wind wheel D1 and the air inlet A1 can be shortened, thereby expanding the air suction range of the axial flow wind wheel D1, increasing the air volume sucked by the axial flow wind wheel D1, and then improving the air supply effect of the air conditioner indoor unit 1000. 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.

[0207] In some embodiments, Fig.17 and 18 As shown, the distance L1 that the rear end blade tip D12 of the axial flow wind wheel D1 extends backward beyond the wind guide surface G1 ranges from 1 mm to 50 mm. That is, the distance that the rear end blade tip D12 of the axial flow wind wheel D1 extends backward beyond the wind guide surface G1 is limited to a reasonable range, so that during the rotation of the axial flow wind wheel D1, the distance between the axial flow wind wheel D1 and the air inlet A1 can be shortened while protecting the safety of the rear end blade tip D12, thereby expanding the air suction range of the axial flow wind wheel D1. (1) In some embodiments, the indoor air conditioner further includes: a heat exchanger B and an air guide cover N.

[0208] The heat exchanger B is placed in the casing A and between the air inlet A1 and the front air outlet A2, and the axial flow fan wheel D1 is located in front of the heat exchanger B. In this way, the axial flow fan wheel D1 and the heat exchanger B are arranged in a staggered manner in the front and back direction in the horizontal direction, so that the structure in the casing A is arranged reasonably and compactly, and the space in the casing A is fully utilized, which is conducive to reducing the volume of the entire casing A.

[0209] There is a first predetermined distance L2 between the rear blade tip D12 of the axial flow wind wheel D1 and the heat exchanger B. In this way, a certain distance is maintained between the rear blade tip D12 of the axial flow wind wheel D1 and the heat exchanger B, and the safety of the rear blade tip D12 can be protected during the rotation of the axial flow wind wheel D1.

[0210] The air guide cover N is arranged on the guide ring G and covers the front end of the first air duct A4. It can be understood that the air guide cover N is arranged on the guide ring G1 to guide the airflow;

[0211] There is a second predetermined distance L3 between the front blade tip D11 of the axial flow wind wheel D1 and the wind guide cover N. In this way, a certain distance is maintained between the front blade tip D11 of the axial flow wind wheel D1 and the wind guide cover N, and the safety of the front blade tip D11 can be protected during the rotation of the axial flow wind wheel D1.

[0212] Specifically, Fig.17 As shown, the first predetermined distance L2 between the rear blade tip D12 of the axial flow wind wheel D1 and the heat exchanger B is not less than 18 mm, and the second predetermined distance L3 between the front blade tip D11 of the axial flow wind wheel D1 and the wind guide cover N is not less than 18 mm. In this way, the front and rear sharp corners of the axial flow wind wheel D1 can be protected from interfering with other surrounding parts during movement, thereby causing damage to the axial flow wind wheel D1. At the same time, it should be noted that the first predetermined distance L2 between the rear blade tip D12 of the axial flow wind wheel D1 and the heat exchanger B and the second predetermined distance L3 between the front blade tip D11 of the axial flow wind wheel D1 and the wind guide cover N are not the larger the better, otherwise, the front-to-back dimensions of the entire air-conditioning indoor unit 1000 will be too large, occupying a large space and having a large mass.

[0213] It can be understood that the first predetermined distance L2 between the rear end blade tip D12 of the axial flow wheel D1 and the heat exchanger B is designed to be no less than 18 mm, and the second predetermined distance L3 between the front end blade tip D11 of the axial flow wheel D1 and the wind guide cover N is designed to be no less than 18 mm, which provides a reasonable axial flow fan blade installation position G2, while ensuring the front and rear safety distance of the axial flow wheel D1, and improving the air supply efficiency of the first fan D.

[0214] In some optional embodiments, such as Fig.17 As shown in FIG. 1 , the radius of the wind sweeping area of ​​the front blade tip D11 of the axial flow wind wheel D1 is equal to the radius of the wind sweeping area of ​​the rear blade tip D12 of the axial flow wind wheel D1. In other words, the radial outer end of the front blade tip D11 and the radial outer end of the rear blade tip D12 are located on the same vertical plane, which can ensure the uniformity of the airflow.

[0215] Specifically, the radius of the swept wind area of ​​the front blade tip D11 of the axial flow wind wheel D1 and the radius of the swept wind area of ​​the rear blade tip D12 of the axial flow wind wheel D1 are both 125mm-130mm. In a specific embodiment, the radius of the swept wind area of ​​the front blade tip D11 of the axial flow wind wheel D1 and the radius of the swept wind area of ​​the rear blade tip D12 of the axial flow wind wheel D1 can both be 128mm, so that the area of ​​the swept wind area of ​​the front blade tip D11 and the rear blade tip D12 is increased as much as possible, which is beneficial to the air supply efficiency of the first fan D, and is also beneficial to shortening the length of the first air duct A4.

[0216] In some optional embodiments, such as Fig.17 As shown, the vertical distance between the outer peripheral edge of the wind sweeping area of ​​the rear blade tip D12 and the inner peripheral wall of the heat exchanger B is not less than 18 mm. It can be understood that the minimum distance between the motion plane of the rear blade tip D12 of the axial flow wind wheel D1 and the inner wall of the heat exchanger B is the vertical distance between the outer peripheral edge of the wind sweeping area of ​​the rear blade tip D12 and the inner peripheral wall of the heat exchanger B, which is not less than 18 mm, so as to ensure that the rear blade tip D12 will not interfere with the heat exchanger B during the rotation of the axial flow wind wheel D1, so as to protect the normal operation of the axial flow wind wheel D1 and the heat exchanger B.

[0217] In some embodiments, Fig.17 and 18 As shown, the distance between the movement plane of the front blade tip D11 of the axial flow wind wheel D1 and the movement plane of the rear blade tip D12 of the axial flow wind wheel D1 is 105mm-115mm. Specifically, the distance between the movement plane of the front blade tip D11 of the axial flow wind wheel D1 and the movement plane of the rear blade tip D12 of the axial flow wind wheel D1 can be 108mm, that is, the length of the wind sweeping area of ​​the axial flow wind wheel D1 in the front-to-back direction is 108mm, thereby, under the condition of meeting the air supply requirements, the axial flow fan occupies a small space, which is conducive to the miniaturization of the air conditioner indoor unit 1000.

[0218] In some optional embodiments, such as Fig.16 As shown, the air conditioner indoor unit 1000 further includes a motor D2 and a motor bracket D22, the motor bracket D22 is arranged at the front end of the guide ring G and includes a cylindrical fixing portion, the motor D2 is arranged on the fixing portion, and the motor shaft D21 passes through the fixing portion backwards and is connected to the axial flow wind wheel D1 by transmission, and the wind guide cover N is arranged around the outside of the fixing portion. That is, the motor bracket D22 is limited and fixed by the fixing portion, and the motor shaft D21 passes through the fixing portion backwards and is connected to the axial flow wind wheel D1 by transmission, so that when the motor D2 is working, under the transmission of the motor shaft D21, the axial flow wind wheel D1 will rotate relatively to guide the flow of wind.

[0219] Specifically, Fig.16As shown, the motor bracket D22 also includes a plurality of connecting rods, which are radially arranged outside the fixing part and connect the fixing part to the guide ring G. The arrangement of the connecting rods is conducive to increasing the rigidity of the motor bracket D22, improving the stability of the motor bracket D22, and thus improving the stability of the motor D2. At the same time, the fixing part is connected to the guide ring G, which can limit and fix the motor bracket D22.

[0220] In other embodiments of the present invention, Figure 7-Figure 24 As shown, the air conditioner indoor unit 1000 includes: a guide ring G, a first fan D and an air 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 used to drive air to flow out of the first air outlet A21 from the first air inlet A1. The air guide cover N is arranged at the first air outlet A21 of the guide ring G, and the air guide cover N is provided with a static blade N1 for the wind blowing through the air guide cover N to rotate and discharge the wind at a predetermined angle.

[0221] It can be understood that the first fan D can inhale the air from the first air inlet A1, and guide the air to flow to the first air outlet A21 through the air guide ring. At this time, the air guide cover N provided at the first air outlet A21 can further guide the wind flowing through, and at the same time, the stator blade N1 can further rotate the wind from the air guide cover N at a predetermined angle to discharge the wind. As a result, the wind inhaled by the motor D2 is further concentrated, and is not easy to be dispersed at the first air outlet A21, thereby enhancing the wind outlet strength and air volume of the first air outlet A21, and also increasing the air volume and air supply range of the air conditioner indoor unit 1000.

[0222] In some embodiments, Fig.19 As shown, the stator blade N1 is movably arranged on the air guide cover N between a first position and a second position, wherein at the first position, the stator blade N1 opens the first air outlet A21, and at the second position, the stator blade N1 closes the first air outlet A21. In this way, when the stator blade N1 opens the first air outlet A21, the air at the first air inlet A1 can flow through the air guide cover N and out of the first air outlet A21, and the air guide cover N can guide the flow direction of the wind and expand the air outlet range. When the stator blade N1 closes the first air outlet A21, the stator blade N1 can also block particles such as dust in the external air, thereby improving the cleanliness of the interior of the air conditioner indoor unit 1000.

[0223] Specifically, Fig. 20As shown, the air guide cover N includes: a swirl mounting frame N2 and a blade driving plate N3. The swirl mounting frame N2 is fixed at the first air outlet A21, and the swirl mounting frame N2 includes an outer ring N21 and a fixed ring N22 located in the middle of the outer ring N21. The blade driving plate N3 is arranged on the swirl mounting frame N2 and can rotate around the outer ring N21. One end of the stationary blade N1 is connected to the fixed ring N22 and can rotate in the radial direction relative to the fixed ring N22. The other end of the stationary blade N1 is connected to the blade driving plate N3 to drive the stationary blade N1 to move between the first position and the second position. In other words, one end of the stationary blade N1 is connected to the fixed ring N22, so that the swirl mounting frame N2 can limit the stationary blade N1, and at the same time, one end of the stationary blade N1 can rotate in the radial direction relative to the fixed ring N22. In this way, when the blade driving plate N3 drives the other end of the stationary blade N1 to rotate, one end of the stationary blade N1 can rotate with the other end of the stationary blade N1 relative to the outer ring N21 of the swirl mounting frame N2.

[0224] Furthermore, if Fig. 20 As shown, a mounting hole N221 is provided on the peripheral wall of the fixing ring N22, and one end of the stationary blade N1 passes through the mounting hole N221 and can rotate in the mounting hole N221. That is, the setting of the mounting hole N221 rotatably connects one end of the stationary blade N1 with the fixing ring N22, so that one end of the stationary blade N1 can relatively rotate in the mounting hole N221.

[0225] (4) In some optional embodiments, such as Fig. 20 As shown, the blade drive plate N3 is sleeved on the outside of the outer ring N21, wherein the outer ring N21 is provided with a mounting groove N212, and the stationary blade N1 is supported in the mounting groove N212. It can be understood that the blade drive plate N3 is sleeved on the outside of the outer ring N21, so that the outer ring N21 can limit the blade drive plate N3. The stationary blade N1 is supported in the mounting groove N212 provided on the outer ring N21, and the mounting groove N212 can limit the stationary blade N1. At the same time, the stationary blade N1 is supported on the outer ring N21, which can improve the stability of the installation of the stationary blade N1.

[0226] In some optional embodiments, the stationary blade N1 includes: a blade N10 and a piston shaft N12. One end of the blade N10 is connected to the fixing ring N22, and the other end of the blade N10 is provided with a sleeve N101. The first end of the piston shaft N12 is connected to the blade drive plate N3, and the second end of the piston shaft N12 is retractable in the sleeve N101 to drive the blade N10 to move between the first position and the second position. That is, the first end of the piston shaft N12 rotates relatively driven by the blade drive plate N3, so that the second end of the piston shaft N12 is retractable to drive the other end of the blade N10 to rotate, and one end of the blade N10 rotates relative to the fixing ring N22 and follows the other end of the blade N10, so that the entire blade N10 can move between the first position and the second position.

[0227] Specifically, Fig.21 As shown, the first end of the piston shaft N12 is connected to the blade drive plate N3 via a ball joint. It is understandable that the setting of the ball joint makes the rotation between the first end of the piston shaft N12 and the blade drive plate N3 more flexible, which can expand the wind guide range of the blade N10.

[0228] In some optional embodiments, such as Fig. 22 and 23 As shown, the blade drive plate N3 is provided with a guide groove N31 extending perpendicular to the direction of the blade drive plate N3, and the air conditioner indoor unit 1000 also includes a drive plate drive device P, which includes: a drive plate motor P1 and a crank P2. One end of the crank P2 is connected to the motor shaft P12 of the drive plate motor, and the other end of the crank P2 can move back and forth in the guide groove N31, and one end of the crank P2 and the other end of the crank P2 are not coaxial. That is, when the drive plate motor P1 is in the working state, the motor shaft P12 of the drive plate motor drives one end of the crank P2 to rotate relatively, and because one end of the crank P2 and the other end of the crank P2 are not coaxial, the other end of the crank P2 can move in the guide groove N31, thereby driving the blade drive plate N3 to rotate relatively.

[0229] In some optional embodiments, such as Fig. 20 As shown, the air guide cover N also includes: a driving base plate N4. The driving base plate N4 is sleeved on the outside of the outer ring N21, and the blade driving plate N3 is arranged above the driving base plate N4. A positioning structure N41 is provided between the driving base plate N4 and the blade driving plate N3, so that the blade driving plate N3 and the driving base plate N4 rotate synchronously. In this way, the driving base plate N4 can fix the blade driving plate N3, increase the rigidity of the blade driving plate N3, and thus make the rotation of the blade driving plate N3 more stable.

[0230] Optionally, the positioning structure N41 includes 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 reinforcing ribs, and can further improve the rigidity of the driving bottom plate N4 and the blade driving plate N3. On the other hand, the positioning column N411 and the positioning sleeve N412 are easy to install and easy to operate.

[0231] Specifically, Fig. 20 As shown, the driving bottom plate N4 and the blade driving plate N3 are respectively provided with through holes corresponding to each other. The through holes are arranged to provide an escape space for the connecting part of the driving bottom plate N4 and the blade driving plate N3, so that the driving bottom plate N4 and the blade driving plate N3 can be connected through a connecting piece, and the driving bottom plate N4 has a limiting and fixing effect on the blade driving plate N3, thereby improving the stability of the relative movement of the blade driving plate N3.

[0232] In some optional embodiments, such as Fig. 20 As shown, the air guide cover N also includes: a swirl blade pressure plate N5. The swirl blade pressure plate N5 is fixed on the swirl mounting frame N2, wherein the stationary blade N1 is arranged between the swirl blade pressure plate N5 and the swirl mounting frame N2. In this way, when the stationary blade N1 rotates, the swirl blade pressure plate N5 and the swirl mounting frame N2 on both sides of the stationary blade N1 can reduce the hidden danger of the stationary blade N1 touching the fingers, thereby improving the safety of the air conditioner indoor unit 1000.

[0233] In some embodiments, Fig. 20 As shown, the stator blades N1 include a plurality of stator blades N1, and the plurality of stator blades N1 are arranged circumferentially around the fixing ring N22. It can be understood that the arrangement of a plurality of stator blades N1 can reduce the design length of a single stator blade N1 and increase the design flexibility of the stator blades N1. At the same time, in order to ensure that the stator blades N1 guide the wind at the first air outlet A21, a plurality of stator blades N1 are arranged circumferentially around the fixing ring N22 so that the distance between adjacent stator blades N1 in the circumferential direction is appropriate, thereby ensuring sufficient wind guiding effect and less wind resistance.

[0234] In some other embodiments of the present invention, Fig. 20 As shown, the air guide cover N is provided with a plurality of mounting lugs N6, and the outer wall of the air guide ring G is provided with a plurality of mounting positions G2, and the plurality of mounting lugs N6 are installed in a one-to-one correspondence with the plurality of mounting positions G2. The mounting lugs N6 provide a specific mounting position G2 point for fixing the air guide cover N and the air guide ring, so that the air guide cover N is connected to the air guide ring G. At the same time, the mounting lugs N6 and the mounting positions are simple to install and easy to operate.

[0235] In some embodiments, Fig. 20 As shown, the air guide cover N includes an inner ring mounting ring N7 and an outer ring mounting ring N8 wound around the inner ring mounting ring N7, and the two ends of the plurality of stationary blades N1 are respectively connected to the inner ring mounting ring N7 and the outer ring mounting ring N8. In this way, the inner ring mounting ring N7 and the outer ring mounting ring N8 play a role in limiting and fixing the stationary blades N1, so that the plurality of stationary blades N1 can be stably connected to the inner ring mounting ring N7 and the outer ring mounting ring N8, thereby improving the stability of the movement of the plurality of stationary blades N1.

[0236] In some embodiments, Fig. 20 As shown, a plurality of stationary blades N1 are radially fixed on the inner ring mounting ring N7 and the outer ring mounting ring N8. Here, the space between the inner ring mounting ring N7 and the outer ring mounting ring N8 can be used to circulate air, and the stationary blades N1 are radially arranged between the inner ring mounting ring N7 and the outer ring mounting ring N8, which can guide the wind passing through to the maximum extent and further gather it to output to the first air outlet A21.

[0237] In some embodiments, Fig.19 and Fig. 20As shown, the cross section of the stator blade N1 in the wind guide cover N accounts for 5% to 15% of the difference between the cross section of the wind guide cover N and the cross section of the inner ring mounting ring N7. That is, the stator blade N1 set between the guide ring G and the inner ring mounting ring N7 occupies part of the air circulation space. In order to ensure the strength of the wind guide cover N itself and its wind guidance, the difference between the cross section of the stator blade N1 in the wind guide cover N and the cross section of the inner ring mounting ring N7 should be reasonably set. Here, when the cross section of the stator blade N1 in the wind guide cover N accounts for 5% to 15% of the difference between the cross section of the wind guide cover N and the cross section of the inner ring mounting ring N7, the wind guide cover N has sufficient structural strength and has a good wind guidance effect.
