[0095] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0096] Reference is made below to Figures 1 - 24 describe the air guiding mechanism of an air conditioner indoor unit according to an embodiment of the present invention.

[0097] The air guiding mechanism J of an air conditioner indoor unit according to an embodiment of the present invention, as Figures 8 - 14 shown, includes: a guiding ring G, a first blower D, a second air outlet A22, and at least one air guiding blade 100.

[0098] The guiding ring G is formed with a first air inlet and a first air outlet A21. In this way, the air sent from the first air inlet can be guided through the guiding ring G and flow out from the first air outlet A21.

[0099] The first blower D is disposed inside the guiding ring G and is used to drive the air to flow out from the first air inlet to the first air outlet A21. That is, the air sent from the first air inlet can be sucked in by the first blower D and guided along the guiding ring G towards the first air outlet A21.

[0100] The second air outlet A22 is disposed around the first air outlet A21. In this way, the air outside the guiding ring G can flow out through the second air outlet A22.

[0101] At least one air guiding blade 100 is used to guide the air flowing out from the first air outlet A21 and at the same time guide the air flowing out from the second air outlet A22. It can be understood that the air flowing out from the first air outlet A21 and the second air outlet A22 can change direction and be discharged into the room under the guidance of the air guiding blade 100. In this way, the air guiding blade 100 can be used to guide the air flowing out from multiple air outlets, which can increase the range of air diversion, thereby improving the air supply effect of the air guiding mechanism J and enhancing the user experience.

[0102] Used to guide the air flowing out from the first air outlet A21 and at the same time guide the air flowing out from the second air outlet A22.

[0103] The air guiding mechanism J of an air conditioner indoor unit according to an embodiment of the present invention, through at least one air guiding blade 100, is used to guide the air flowing out from the first air outlet A21 and the second air outlet A22 at the same time, which can expand the range of air diversion, reduce the occupied space of the air guiding mechanism J, thereby improving the air supply effect of the air guiding mechanism J and enhancing the user experience.

[0104] In some embodiments, as Figure 8 and Figure 9 shown, the air guiding mechanism J of the air conditioner indoor unit 1000 further includes: an air outlet frame F. The air outlet frame F includes a rear plate F1, and ventilation holes F4 are provided on the rear plate F1. A flow guiding ring G is arranged in the air outlet frame F and the axis of the flow guiding ring G is perpendicular to the ventilation holes F4. A first air duct A4 extending through its length in the axial direction thereof is defined in the flow guiding ring G, and the first air duct A4 communicates with the air inlet A1 and the first air outlet A21. The second air outlet A22 is defined between the air outlet frame F and the flow guiding ring G. It can be understood that a part of the air sent from the air inlet A1 can flow forward through the ventilation holes F4, and after being guided by the first air duct A4, it enters the room from the first air outlet A21. Another part of the air sent from the air inlet A1 can be guided through the position between the air outlet frame F and the flow guiding ring G and enters the room from the second air outlet A22. In this way, the air at the air inlet A1 can be guided in various ways, increasing the range of air flow, thereby improving the air supply effect of the air guiding mechanism J.

[0105] In some embodiments, as Figure 8 shown, the air guiding vane 100 includes: a plurality of transverse guide vanes 110. The plurality of transverse guide vanes 110 are respectively rotatably arranged in the air outlet frame F and are located on the front side of the flow guiding ring G. The plurality of transverse guide vanes 110 are spaced apart in the up and down direction. A groove 1101 for accommodating the flow guiding ring G is provided on at least a part of the plurality of transverse guide vanes 110, and parts of the transverse guide vanes 110 on both sides of the groove 1101 extend backward to the rear side of the front end of the flow guiding ring G. It can be understood that the provision of the groove 1101 enables parts of the transverse guide vanes 110 on both sides of the groove 1101 to extend backward to the rear side of the front end of the flow guiding ring G. In this way, the distance between the transverse guide vanes 110 and the first blower D is shortened, increasing the air volume of the air supply, 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.

[0106] Specifically, as Figures 8 - 12As shown in the figure, the air guiding mechanism J further includes: a connecting rod 120 and a driving device 160. The connecting rod 120 extends in the up and 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 vanes N10, 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. Furthermore, the rotating transverse guide vane 110 can guide the air flow at the first air outlet A21 and the second air outlet A22.

[0107] Furthermore, as Figure 9 shown, the air outlet frame F further 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. Both ends of each transverse guide vane 110 are rotatably connected to the left side plate F2 and the right side plate F3 respectively. The driving device 160 is arranged on the left side plate F2 or the right side plate F3 and is in transmission connection with at least one of the transverse guide vanes 110. In this way, the driving device 160 can drive the transverse vane N10, so that the transverse guide vane 110 rotates relative to the left side plate F2 and the right side plate F3, and then the connecting rod 120 connected to the transverse guide vane 110 moves together with the transverse guide vane 110. Furthermore, the other transverse guide vanes 110 connected to the connecting rod 120 will rotate together with the connecting rod 120. Furthermore, the rotating transverse guide vane 110 can guide the air flow at the first air outlet A21 and the second air outlet A22.

[0108] In some alternative embodiments, as Figures 9 - 11 shown, a plurality of hooks 1201 are provided on the connecting rod 120, and a plurality of transverse guide vanes 110 are respectively and correspondingly connected to the plurality of hooks 1201. A hanging post 1103 is provided on the transverse guide vane 110, and the hanging post 1103 cooperates with the hook 1201. That is, through the cooperation of the hanging post 1103 and the hook 1201, the connecting rod 120 is connected to the transverse guide vane 110, and under the action of the friction force between the hanging post 1103 and the hook 1201, the connecting rod 120 and the transverse guide vane 110 can move together.

[0109] Specifically, as Figure 13As shown in the figure, the transverse guide vane 110 is provided with an installation groove 1102 that opens backward, and a hanging column 1103 is arranged in the installation groove 1102. Among them, the hook 1201 hooks the hanging column 1103 from top to bottom or from bottom to top, and the hanging columns 1103 on each transverse guide vane 110 correspond to each other in the up and down directions. In this way, the hook 1201 can hook the hanging column 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.

[0110] Furthermore, as Figure 12 shown in the figure, each hook 1201 includes a horizontally extending portion 1201A and a vertically extending portion 1201B. The horizontally extending portion 1201A and the vertically extending portion 1201B are perpendicularly connected to each other, and the horizontally extending portion 1201A is connected to the connecting rod 120. The cross-section of the horizontally extending portion 1201A is semicircular. It can be understood that the horizontally extending portion 1201A can provide a mating surface for the hanging column 1103. After assembly, there is a certain frictional force between the horizontally extending portion 1201A and the hanging column 1103, so that the hanging column 1103 rotates together on the hook 1201. For example, when the driving device 160 drives at least one of the plurality of transverse guide vanes 110, the frictional force between the hanging column 1103 on the blade N10 and the arc surface can drive the connecting rod 120 to rotate together, and then drive the other blades N10 on the hook 1201 to rotate relative to each other. When the driving device 160 directly drives the connecting rod 120, the frictional force between the hanging column 1103 and the horizontally extending portion 1201A will directly drive the transverse guide vane 110 to rotate following the connecting rod 120, thereby realizing air guiding.

[0111] In this embodiment, the hanging column 1103 can pass through the vertically extending portion 1201B to fit with the outer surface of the horizontally extending portion 1201A, so that it is not necessary to assemble the blade N10 on the hook 1201 by extrusion. In this way, the deformation of the hook 1201 can be reduced as much as possible, thereby increasing the structural strength of the hook 1201 and improving the assembly efficiency of the blade N10 and the hook 1201.

[0112] Optionally, as Figure 10As shown, at one end of the two ends of the length of the connecting rod 120, there is a hook 1201, and at the other end of the two ends of the length of the connecting rod 120, there is 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 install the transverse guide vane 110. In this way, when the transverse guide vane 110 is installed on the hook 1201, the transverse stopper 1202 perpendicular to the length of the connecting rod 120 provided at the other end of the two ends of the length of the connecting rod 120 can provide a stop position for clamping, thus facilitating the installation of the transverse guide vane 110.

[0113] In some alternative embodiments, as Figure 13 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 recesses forward. The lowermost transverse guide vane 110 among the multiple transverse guide vanes 110 is arranged lower than the lowermost end of the guide vane ring G. In the lowermost transverse guide vane 110, the installation groove 1102 is formed at the rear end of the transverse guide vane 110 and recesses forward. It can be understood that the transverse guide vane 110 provided with a groove 1101 can make a part of the transverse guide vane 110 extend backward to the rear side of the front end of the guide vane ring G. In this way, the distance between the transverse guide vane 110 and the axial flow fan is shortened, so that the air volume of the air supply increases, and the air supply range of the guide vane 100 can be expanded, thereby improving the air supply effect of the guide vane 100. The lowermost transverse guide vane 110 is arranged lower than the lowermost end of the guide vane ring G, which can be used to guide the air sent by the second air duct A5 and then discharged outdoors through the second air outlet A22.

[0114] In some alternative embodiments, as Figure 8 and Figure 13 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 straight, and the groove 1101 is formed in the middle of the rear end of the transverse guide vane 110, and the lengths of the grooves 1101 of the multiple transverse guide vanes 110 gradually decrease in the direction from the center of the guide vane ring G to the upper and lower sides. In this embodiment, the front end of the transverse guide vane 110 is arc-shaped and the rear end of the transverse guide vane 110 is straight. In this way, the space required for the rotation of the transverse guide vane 110 is reduced, which is beneficial to the miniaturization of the air guiding mechanism J. The groove 1101 in the middle of the rear end of the transverse guide vane 110 has a length that gradually decreases in the direction from the middle to the upper and lower sides in the radial direction of the guide vane ring G. It can be understood that the transverse dimension of the guide vane ring G gradually decreases from the center to the upper and lower sides, and a part of the transverse guide vane 110 provided with a groove 1101 is arranged to extend backward to the rear side of the front end of the guide vane ring G. In this way, the fact that the length of the groove 1101 gradually decreases in the direction from the center of the guide vane ring G to the upper and lower sides is beneficial to the cooperation with the guide vane ring G.

[0115] Optionally, the range of the vertical distance between the side wall of the groove 1101 and the outer wall of the flow guide ring G is: 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 flow guide ring G, so that the transverse blade N10 does not contact the flow guide ring G during rotation, ensuring the rigidity of the transverse guide vane 110.

[0116] Furthermore, the length range of the groove 1101 is: 100 mm to 350 mm, and the depth range of the groove 1101 is 20 mm to 30 mm. In this way, the rear ends on each transverse guide vane 110 correspond in the up and down direction, and the distance that the part of the transverse guide vane 110 extends backward to the rear side of the front end of the flow guide ring G is appropriate. Thus, on the premise of not affecting the normal operation of the first fan D, the distance between the transverse guide vane 110 and the first fan D can be shortened, the air volume of the air supply is increased, and the air supply range of the transverse guide vane 110 can be expanded.

[0117] In some embodiments, as Figure 8 and Figure 9 shown, the air guide vane 100 further 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 enters from the rear of the air outlet frame F. For another example, air is led out from the second air outlet A22, or air is led out 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 following longitudinal guide vane 130.

[0118] 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 vanes 1301 move, the second guide vanes 1302 also move, and the first guide vanes 1301 and the second guide vanes 1302 move and stop simultaneously.

[0119] The length of the first guide vanes 1301 is greater than the length of the second guide vanes 1302. The plurality of first guide vanes 1301 are pivotally arranged on the air outlet frame F, and the plurality of second guide vanes 1302 are pivotally arranged between the flow guide ring G and the air outlet frame F. That is, the first guide vanes 1301 are rotatable relative to the air outlet frame F, while the second guide vanes 1302 are rotatable relative to the air outlet frame F and the flow guide ring G.

[0120] The air guide driving mechanism 150 drives the longitudinal guide vane 130 to swing. The air guide driving mechanism 150 controls the movement or stop of the longitudinal guide vane 130.

[0121] As can be seen from the above structure, the first air guiding vane 1301 is pivotally arranged on the air outlet frame F, and the second air guiding vane 1302 is pivotally arranged on the air guiding ring G and the air outlet frame F, so that the air guiding vane 100 has a stable rotation support point and a reliable connection. During the rotation of the air guiding vane 100, it is not easy to disengage from the air outlet frame F or the air guiding ring G, with good reliability, and the air guiding vane 100 can continuously and stably guide the air.

[0122] It can be understood that the first air guiding vane 1301 is relatively long, and both ends thereof are connected to the air outlet frame F, while the second air guiding vane 1302 is relatively short and has a larger number, and is respectively connected to the air guiding ring G and the air outlet frame F. Compared with all being the first air guiding vanes 1301 with a longer length, the present invention provides multiple shorter second air guiding vanes 1302, which greatly enhances the overall rigidity of the air guiding vane 100 and reduces the air outlet resistance. In addition, compared with arranging all the air guiding vanes 100 on the air outlet frame F, in the present invention, one end of the second air guiding vane 1302 is arranged on the air outlet frame F and the other end is arranged on the air guiding ring G, so that the second air guiding vane 1302 is easy to arrange and connect, and is not easy to deform or come off after connection. In addition, the longitudinal guide vane 130 of the present invention does not need to be arranged on the air outlet side of the entire air outlet frame F, but can be selectively arranged in a partial area of the air outlet frame F, and the arrangement mode of the second air guiding vane 1302 is more flexible.

[0123] Specifically, as Figure 9 shown, the multiple second air guiding vanes 1302 include multiple first-group air guiding vanes 1302A and multiple second-group air guiding vanes 1302B. The first-group air guiding vanes 1302A are arranged above the air guiding ring G, and the second-group air guiding vanes 1302B are arranged below the air guiding ring G. That is, the upper end of the first-group air guiding vanes 1302A located above the air guiding ring G is pivotally connected to the air outlet frame F, and the lower end is pivotally connected to the air guiding ring G; the upper end of the second-group air guiding vanes 1302B located below the air guiding ring G is pivotally connected to the air guiding ring G, and the lower end is pivotally connected to the air outlet frame F.

[0124] In some alternative embodiments, as Figure 9As shown, the longitudinal guide vane 130 further includes a sweeping link 170. The guide vane driving mechanism 150 drives the sweeping link 170 to reciprocate. The first guide vane 1301 and the second guide vane 1302 are respectively slidably connected to the sweeping link 170. The longitudinal guide vane 130 can be in a left - right sweeping state or an up - down sweeping state. When the longitudinal guide vane 130 is in the left - right sweeping state, the sweeping link 170 reciprocates left and right under the action of the guide vane driving mechanism 150; when the longitudinal guide vane 130 is in the up - down sweeping state, the sweeping link 170 reciprocates up and down under the action of the guide vane driving mechanism 150. When the longitudinal guide vane 130 is in the up - down sweeping state, the sweeping link 170 reciprocates up and down under the action of the guide vane driving mechanism 150. No specific limitation is made here.

[0125] Specifically, as Figure 14 and Figure 15 shown, the sweeping link 170 includes: a driving sweeping link 1701 and a driven sweeping link 1703. A chute 1704 is provided on the driving sweeping link 1701. One end of the first guide vane 1301 is provided with a first guide rod 140 that slidably cooperates with the chute 1704. The other end of the first guide vane 1301 is connected to the driven sweeping link 1703. A second guide rod that slidably cooperates with the chute 1704 is provided at the end of the second guide vane 1302 close to the driving sweeping link 1701. The end of the second guide vane 1302 close to the driven sweeping link 1703 is connected to the driven sweeping link 1703. Thus, the first guide vane 1301 and the second guide vane 1302 can form a linkage movement. In addition to moving and stopping together, the movement states such as the swing angle of the first guide vane 1301 and the second guide vane 1302 can also be kept consistent.

[0126] In some alternative embodiments, as Figure 9 and Figure 15 shown, the driving sweeping link 1701 and the driven sweeping link 1703 are arranged in parallel. The guide vane driving mechanism 150 drives the driving sweeping link 1701 to reciprocate. The driving sweeping link 1701 drives the driven sweeping link 1703 to reciprocate through the first guide vane 1301. That is, when the guide vane driving mechanism 150 drives the driving sweeping link 1701 to reciprocate left and right, the driving sweeping link 1701 simultaneously drives the first guide vane 1301 and the first group of guide vanes 1302A to move. The first guide vane 1301 on the driving sweeping link 1701 transmits the acting force to the driven sweeping link 1703 connected thereto. The driven sweeping link 1703 follows the movement, and the driven sweeping link 1703 further drives the second group of guide vanes 1302B to move. Therefore, the first guide vane 1301 and the second guide vane 1302 of the present invention have high synchronism, precise swing angle control, simple arrangement of the guide vane driving mechanism 150, and less occupied layout space.

[0127] Specifically, as Figure 9 and Figure 15 shown, when the active air-sweeping connecting rod 1701 reciprocates, the first guiding rod 140 slides from one end of the sliding groove 1704 to the other end, the first air-guiding blade 1301 rotates 90 degrees, the second guiding rod slides from one end of the sliding groove 1704 to the other end, and the second air-guiding 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 air-guiding mechanism J has the first motion state and the second motion state, and the air-guiding mechanism J can be converted between the first motion state and the second motion state.

[0128] Optionally, as Figure 9 and Figure 15 shown, the sliding groove 1704 is formed into a semi-circular or arc shape, and when the first guiding rod 140 and the second guiding rod slide in the sliding groove 1704, it is smooth, and the guiding of the sliding groove 1704 is convenient.

[0129] In some alternative embodiments, as Figure 9 and Figure 15 shown, the air-guiding driving mechanism 150 includes a sweeping motor 1501 and a transmission gear 1502. The sweeping motor 1501 drives the transmission gear 1502 to rotate, and the active air-sweeping connecting rod 1701 is provided with a transmission tooth 1702 that cooperates with the transmission gear 1502. Thus, when the sweeping motor 1501 rotates, the active air-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.

[0130] In some alternative embodiments, as Figure 9 and Figure 15 shown, the air-sweeping connecting rod 170 includes two active air-sweeping connecting rods 1701 arranged in parallel. The air-guiding driving mechanism 150 includes two and respectively drives the two active air-sweeping connecting rods 1701 to reciprocate. Both ends of the first air-guiding blade 1301 are slidably connected to the two active air-sweeping connecting rods 1701, and one end of the second air-guiding blade 1302 is slidably connected to one of the active air-sweeping connecting rods 1701. That is, the first air-guiding blade 1301 and the second air-guiding blade 1302 are respectively driven by the active air-sweeping connecting rod 1701 and directly change the motion state. At this time, the driving transmissions of the air-guiding driving mechanism 150 should be kept synchronized as much as possible so that the motion states of all the first air-guiding blades 1301 and all the second air-guiding blades 1302 are consistent.

[0131] In some alternative embodiments, as Figure 8 and Figure 9As 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.

[0132] Alternatively, if Figure 8 and Figure 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 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.

[0133] 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.

[0134] Alternatively, if Figure 8 and Figure 9As shown, the longitudinal guide vane 130 has a first motion state and a second motion state, and the longitudinal guide vane 130 is convertible between the first motion state and the second motion state. Among them, in the first motion state, the projected area of the first air guiding vane 1301 and the second air guiding vane 1302 in the air outlet frame F accounts for 80% - 90% of the difference between the cross-section of the air outlet frame F and the cross-section of the air guiding ring G; in the second motion state, the projected area of the first air guiding vane 1301 and the second air guiding vane 1302 in the air outlet frame F accounts for 5% - 10% of the difference between the cross-section of the air outlet frame F and the cross-section of the air guiding ring G.

[0135] It can be understood that in the first motion state, when the projected area of the first air guiding vane 1301 and the second air guiding vane 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 air guiding ring G, the sidewall effect formed by the first air guiding vane 1301 and the second air guiding vane 1302 in the first motion state will become weak. When the air between the air guiding ring G and the air outlet frame F is designed to be upper air outlet, the air volume of the upwardly discharged air is insufficient. When the projected area of the first air guiding vane 1301 and the second air guiding vane 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 air guiding ring G, in the first motion state, the first air guiding vane 1301 and the second air guiding vane 1302 are prone to overlap and interference.

[0136] In the second motion state, the projected area of the first air guiding vane 1301 and the second air guiding vane 1302 in the air outlet frame F accounts for 5% - 10% of the difference between the cross-section of the air outlet frame F and the cross-section of the air guiding ring G. It can be understood that when the projected area of the first air guiding vane 1301 and the second air guiding vane 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 air guiding ring G, the thickness of the first air guiding vane 1301 and the second air guiding vane 1302 will be too thin, and the stiffness and strength are insufficient, and it is easy to deform. When the projected area of the first air guiding vane 1301 and the second air guiding vane 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 air guiding ring G, the first air guiding vane 1301 and the second air guiding vane 1302 generate a large wind resistance to the air between the air guiding ring G and the air outlet frame F in the second motion state, and the air outlet is not smooth enough.

[0137] Optionally, as Figure 8 shown, both the front and the back of the air guiding ring G are open, and an axial flow fan or a cross-flow fan is provided in the air guiding ring G. The air inhaled by the axial flow fan or the cross-flow fan is discharged along the air guiding ring G towards the first air outlet A21.

[0138] Next, refer to Figures 1 - 24 , and describe in detail the air conditioner indoor unit 1000 according to the embodiment of the present invention.

[0139] In some embodiments, such as Figure 1 and Figure 7 shown, it includes: a housing A, a first air outlet A21, a second air outlet A22, and an air outlet grille L. The housing A includes a main body A6 and a front panel A8, and an air inlet A1 is formed on the housing A. The second air outlet A22 is arranged around the first air outlet A21, and a front air outlet A2 is provided on the front panel A8, and the outer edge of the front air outlet A2 corresponds to the outer edge of the second air outlet A22; the air outlet grille L covers the front ends of the first air outlet A21 and the second air outlet A22 and is connected to the front air outlet A2.

[0140] The air outlet grille L covers the front ends 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 set open, resulting in the internal structure of the air conditioner being exposed on the outside, and it is relatively single and not beautiful in appearance. In this solution, by arranging the air outlet grille L at the front ends of the first air outlet A21 and the second air outlet A22, the structure inside the air conditioner can be protected inside, which is more secure, and the air flow can be made more uniform, thereby enhancing the air outlet effect and improving the user experience. In addition, the shape of the air outlet grille L can be changed to make it more diverse and more beautiful in shape.

[0141] It should be noted that the air heated and exchanged in the air conditioner can be divided into two parts and sent out. One part of the air reaches the first air outlet A21 and is sent outwards, and after encountering the air outlet grille L, the flow rate slows down and the air is sent out evenly; the other part of the air is sent outwards through the second air outlet A22 and then through the air outlet grille L. Thus, the air outlet range of the air conditioner can be increased, and the regulation effect on the indoor air can be improved. By arranging the air outlet grille L at the front ends of the first air outlet A21 and the second air outlet A22, the structure of the indoor unit 1000 of the air conditioner has diversity, and the air outlet effect can be further enhanced, thereby improving the user experience.

[0142] In some embodiments, such as Figure 1 and Figure 3 shown, the front end of the main body A6 has an open mouth 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 mouth A7. In this way, the air heated and exchanged in the air conditioner can also be sent outwards through the un-covered part of the open mouth A7. Specifically, in addition to the front panel A8 having the front air outlet A2 on the entire housing, the un-covered part of the open mouth A7 on the main body A6 also serves as another air outlet, so that there are multiple air outlets for air outlet on the housing. The cold or hot air after heat exchange in the air conditioner can be sent outwards through multiple outlets, and the air outlet range is larger and the effect is better.

[0143] Specifically, such as Figure 2 and Figure 3As shown, the casing A is further provided with a third air outlet A3, which is located above the front air outlet A2 and blows air forward. It should be noted that Figure 2 and Figure 3 the arrows in indicate the direction of air 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 ability of the air conditioner. When the air conditioner blows air outwards, it can blow air outwards from the front air outlet A2 of the front panel A8, and can also blow air upwards from the third air outlet A3 at the top of the air conditioner, thereby further improving the air outlet effect. It should be noted that the front here in the present invention refers to the side of the air conditioner facing the user. The above-mentioned third air outlet A3 can be defined by the open part A7 on the main body A6 that is not covered.

[0144] In some embodiments, as Figure 3 and Figure 4 shown, the first air outlet A21 is communicated with the air inlet A1, and in the first air duct A4 formed by the communication, a first fan D is provided; the second air outlet A22 is communicated with the air inlet A1, and in the second air duct A5 formed by the communication, a second fan E is provided; the first fan D and the second fan E are independently controlled respectively. In this way, the first fan D is used to drive air to flow from the air inlet A1 to the front air outlet A2, that is, the air sent from the air inlet A1 can be driven by the first fan D and led out from the front air outlet A2, and the second fan E is used to drive air to flow from the air inlet A1 to the front air outlet A2 or the above-mentioned uncovered open part A7.

[0145] In some embodiments, as Figure 5 shown, there is a predetermined gap A71 between the upper edge part of the front panel A8 and the upper edge part of the open part A7. That is to say, the predetermined gap A71 defines another air outlet except the front air outlet A2 at the front end of the indoor unit 1000 of the air conditioner, and the other air outlet is located at the top of the air conditioner. The third air outlet A3 and the front air outlet A2 below it send air together. When the air conditioner blows air outwards, it can blow air outwards from the front air outlet A2 of the front panel A8, and can also blow air upwards from the third air outlet A3 of the air conditioner, so as to expand the air outlet range of the air conditioner, thereby further improving the front air outlet ability of the air conditioner, and further enhancing the air outlet effect. It should be noted that the front here in the present invention refers to the side of the air conditioner facing the user.

[0146] Specifically, the lower edge part of the front panel A8 can be attached to the lower edge part of the open part A7, the left edge part of the front panel A8 can be attached to the left edge part of the open part A7, and the right edge part of the front panel A8 can be attached to the right edge part of the open part A7. Thus, the above-mentioned edge parts cover each other, ensuring no gap between them, that is, ensuring 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.

[0147] Furthermore, as Figure 5 shown, in the front view of the cabinet A, the range of the predetermined gap A71 can be 40 mm to 150 mm. It can be understood that if the predetermined gap A71 is too small, it is not conducive to the rapid discharge of the heat-exchanged air in the air conditioner, which easily causes the air to accumulate in the housing, resulting in an increase in the internal pressure and a problem of poor heat dissipation effect; while if the predetermined gap A71 is too large, the heat-exchanged air will be discharged from the other air outlet instantly, resulting in uneven air flow and being not conducive to the circulation of air in the room. Therefore, setting the range of the predetermined gap A71 to 40 mm to 150 mm can ensure that in this area range, the air flowing through the predetermined gap A71 has a better effect.

[0148] In a specific embodiment, the size of the predetermined gap A71 can be 40 mm. At this time, the size gap 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 heat-exchanged air of the air conditioner is mainly discharged from the front air outlet A2 and supplemented by the top air outlet formed by the predetermined gap A71, thereby playing a role in improving the air outlet effect of the air conditioner.

[0149] In a specific embodiment, the size of the predetermined gap A71 can be 66 mm. It can be understood that this can not only ensure a better air discharge effect of the air in the air conditioner, but also ensure the circulation of air in the room. At this time, the air outlet effect of the predetermined gap A71 is the best.

[0150] In a specific embodiment, the size of the predetermined gap A71 can also be 150 mm. Then it can be understood that at this time, the size gap 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 heat-exchanged air of the air conditioner is mainly discharged from the two air outlets, and their functions are basically the same, jointly playing a role in adjusting the external air outlet effect of the air conditioner.

[0151] In some embodiments, as Figures 1 - 5 shown, the height range of the front panel A8 can be 1300 mm to 1800 mm. Thus, the height of the front air outlet A2 is suitable for the height of the human body. The air discharged from the front air outlet A2 can directly blow to the area where the human body is located. At the same time, combined with the above-mentioned third air outlet A3 structure, the height of the third air outlet A3 is higher than the area where the human body is located. At this time, the air discharged from the third air outlet A3 blows above the human body, and then the air flow naturally sinks to the area where the human body is located. At this time, the human body will not feel the wind or feel a weak wind, thereby improving the comfort of the user.

[0152] The ratio range between the height of the front panel A8 and the height of the air outlet grille L is: 2 to 5, and the ratio range between the area of the front panel A8 and the area of the air outlet grille L is 3 to 6. The following are optional embodiments:

[0153] 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 is relatively small. When the air conditioner blows air, the air is relatively concentrated at a lower height in the room.

[0154] 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 relative air outlet is relatively large. When the air conditioner blows air, the air is relatively concentrated at a higher height in the room.

[0155] In a specific embodiment, the ratio between the height of the front panel A8 and the height of the air outlet grille L can be 3.75, and the ratio between the area of the front panel A8 and the area of the air outlet grille L can be 4.5. This is more conducive to production and manufacturing.

[0156] 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. At this time, the ratio of their heights is appropriate, and it is more beautiful in appearance.

[0157] In a specific embodiment, the distance between the bottom of the air outlet grille L and the bottom of the main body A6 is 1234 mm. Similarly, the position of the front air outlet A2 can be determined through the position of the air outlet grille L. In this way, the height positions of the air outlet grille L and the front air outlet A2 are the most suitable, which is conducive to the air conditioner blowing air outwards. In addition, when the air outlet grille L is at this height position, the air conditioner can avoid directly blowing on children when blowing air outwards, and avoid children getting colds or other diseases caused by direct blowing in the cold air state.

[0158] In some embodiments, as Figure 5 shown, the size range of the air outlet grille L in the left - right direction can be: 350 mm to 450 mm. 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 - blowing ability of the front air outlet A2. Considering the actual size of the air conditioner, the size of the air outlet grille L is more suitable within this size range. Similarly, the air outlet grille L with this size is convenient to manufacture and is conducive to production.

[0159] In a specific embodiment, the size of the air outlet grille L in the left - right direction can be 350 mm. At this time, the size of the air outlet grille L is the smallest, and the air - blowing ability of the front air outlet A2 is restricted to a certain extent to achieve a stable air - blowing effect of the front air outlet A2.

[0160] In a specific embodiment, the size of the air outlet grille L in the left - right direction can be 382 mm. Thus, the size of the air outlet grille L is appropriate and the air - supply effect is good.

[0161] In a specific embodiment, the size of the air outlet grille L in the left-right direction can also be 450 mm. At this time, the size of the air outlet grille L is the largest, and the flow rate of the air blown outwards from the front air outlet A2 is the largest, which helps to further expand the air outlet range of the air conditioner.

[0162] More specifically, as Figure 5 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 at this time. Thus, the area of the air outlet grille L at this size can completely cover the front air outlet A2.

[0163] In some alternative embodiments, as Figure 6 shown, a plurality of equilateral triangle-shaped mesh holes L1 are uniformly arranged on the air outlet grille L, and the side length range of each mesh hole L1 is 1 mm to 20 mm. Thus, making the mesh holes L1 in the shape of an equilateral triangle can play a better decorative role and make the whole more beautiful. Secondly, if the mesh holes L1 are too small, it is not conducive to the delivery of air, and if the mesh holes L1 are too large, it cannot achieve a certain air resistance effect. Therefore, the side length range of the mesh holes L1 is set to 1 mm to 20 mm, which is both conducive to the delivery of air and can play a certain air resistance role, improving the air outlet effect.

[0164] In a specific embodiment, the side length of the equilateral triangle-shaped mesh hole L1 on the air outlet grille L can be 1 mm. That is to say, at this time, the size of the mesh hole L1 on the air outlet grille L is the smallest and densest, it is not easy to observe the internal structure of the air conditioner, and it has a more decorative effect in appearance and looks more beautiful.

[0165] In a specific embodiment, the side length of the equilateral triangle-shaped mesh hole L1 on the air outlet grille L can also be 20 mm. That is to say, at this time, the size of the mesh hole L1 on the air outlet grille L is the largest and the loosest, which is conducive to the air outlet of the air conditioner.

[0166] In a specific embodiment, the side lengths of a plurality of mesh holes L1 can be 13.5 mm. This can facilitate production and manufacturing and reduce costs.

[0167] In other embodiments, the shape of the mesh holes L1 is not limited to an equilateral triangle shape, and can also be set to other shapes. For example, the mesh holes L1 can also be diamond-shaped, rectangular, circular or oval (not shown in the figure). Similarly, when the mesh holes L1 are diamond-shaped, the side length dimension of the diamond can be 13.5 mm, so as to ensure that the mesh holes L1 have a good ventilation effect.

[0168] Of course, in other embodiments of the present invention, the shape of the mesh L1 can be diverse and can be composed of a combination of multiple graphics. For example, the air outlet grille L can be composed of multiple concentric circular regions (not shown in the figure). The shape of the mesh L1 in the middle concentric circular region is an equilateral triangle, the mesh L1 in the outer concentric circular region is a rhombus, and the mesh L1 in the outermost concentric circular region is a direction, making the overall appearance more beautiful. Another example is that the air outlet grille L can be composed of multiple square ring regions (not shown in the figure). The mesh L1 in the innermost square ring region is a rhombus, the mesh L1 in the outer square ring region is a square, and the mesh L1 in the outermost square ring region is an equilateral triangle, which can also enhance the aesthetics.

[0169] In some alternative embodiments, as Figure 6 shown, the ratio range of the sum of the areas of multiple meshes L1 to the area of the air outlet is 0.5 to 0.8. In this way, that is to say, the air outlet grille L as a whole can play a certain air resistance effect. When the air that has undergone heat exchange in the air conditioner indoor unit 1000 is sent out from the front air outlet A2, it first acts on the air outlet grille L, and after being blocked to a certain extent, it spreads out and blows outwards through the meshes L1, thus avoiding the concentrated outward blowing of the heat-exchanged air. Moreover, part of the air conditioner air will still directly pass through the meshes L1 and blow outwards, but at this time, the wind feeling of the human body has been weakened to a certain extent, with a more suitable comfort level. And the other part of the air will spread along the circumferential direction of the air outlet grille L and blow out from the nearest mesh L1, so that the meshes L1 at the remaining positions on the air outlet grille L all have air passing through, and an even blowing effect is achieved, improving the wind feeling of the air conditioner blowing.

[0170] In some embodiments, as Figure 1 shown, the front surface of the front panel A8 is an arc surface. The left and right edge parts of the front panel A8 extend backward, and the bending radius range of the left and right edge parts of the front panel A8 is 30 mm to 80 mm. By this means, making the front surface of the front panel A8 an arc surface enables the front panel A8 to have a certain depth in the front-rear direction, and it can play a certain wrapping role when cooperating with the front end surface of the main body A6, making the interior of the casing A more compact, and at the same time, 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 at the left and right edges of the casing A, which can reduce the damage to the human body during handling and is more secure. 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.

[0171] In a specific embodiment, the bending radii of the left and right edge portions of the front panel A8 are 46 mm. It can be understood that at this time, these are the optimal values for the bending radii of the left and right edge portions of the front panel A8, which is more conducive to the front panel A8 being combined with the main body A6.

[0172] Of course, in a specific example, the bending radii of the left and right edge portions of the front panel A8 can be 30 mm. At this time, it is more convenient to manufacture the front panel A8, which can reduce the manufacturing difficulty and save the manufacturing cost.

[0173] In addition, in other examples, the bending radii of the left and right edge portions of the front panel A8 can also be 80 mm. At this time, the depth when the front panel A8 is combined with the main body A6 is deeper, that is, the combination of the two is more secure.

[0174] In other embodiments, the dimension range of the front panel A8 in the front - rear direction is 60 mm to 100 mm. Specifically, the dimension of the front panel A8 in the front - rear direction is 70 mm. It can be understood that at this time, 70 mm is the optimal dimension of the front panel A8 in the front - rear direction. It can also be understood that the depth of the front panel A8 in the front - rear direction is 70 mm, which is conducive to the front panel A8 closely adhering to and wrapping around the main body A6 to achieve the combination of the two.

[0175] The combination of the two.

[0176] In other embodiments, the thickness of the middle part of the main body A6 in the front - rear direction is 118 mm, and the thicknesses of the upper and lower end parts of the main body A6 in the front - rear direction are 207 mm. It can be understood that the values at this time are the optimal dimensions of the main body A6 in the front - rear direction, but are not limited to this. With this dimension design, the overall housing A is more slender, has a stronger three - dimensional sense, makes the internal structure more compact, has a smaller volume, and does not occupy too much space, thus facilitating placement.

[0177] In some embodiments of the present invention, as Figure 3 and Figure 4 shown, the air conditioner indoor unit 1000 further includes a flow - guiding ring G with a circular cross - section in the front - rear direction. A first air duct A4 is defined within the flow - guiding ring G, and a second air duct A5 is defined between the outer wall of the flow - guiding ring G and the inner wall of the housing A. It can be understood that a part of the air sent from the air inlet A1 can be diverted through the second air outlet A22 and then enter the room to adjust the air.

[0178] Further, as Figure 4 and Figure 7As shown, the air conditioner indoor unit 1000 further includes an air outlet frame F with a rectangular cross-section in the front-rear direction. The air outlet frame F is arranged inside the casing A, and a flow guide ring G is arranged inside the air outlet frame F. A second air outlet A22 is defined between the outer wall of the flow 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 flow 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 diverted in various ways, increasing the range of air flow, thereby improving the air supply effect of the air conditioner indoor unit 1000.

[0179] Among them, a part of the air entering from the air inlet A1 can be diverted through 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 diverted through the position between the air outlet frame F and the flow 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 diverted in various ways, increasing the range of air flow, thereby improving the air supply effect of the air guiding mechanism J.

[0180] The first fan D and the second fan E are independently controlled respectively, that is, the control of the first fan D and the second fan E is independent of each other and not affected by each other. Specifically, the first fan D and the second fan E can work simultaneously or one of them can be used for air guiding. The rotational speeds of the first fan D and the second fan E can be the same or different. Thus, the air supply modes of the air conditioner indoor unit 1000 can be diversified and the air supply effect is good.

[0181] Specifically, the first fan D can be an axial flow fan or a cross-flow fan. The second fan E can be a centrifugal fan or a cross-flow fan. Thus, the structures of the first fan D and the second fan E can be more diverse and the air supply effect is better.

[0182] It should be noted here 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 an inclined flow fan, etc.

[0183] In some embodiments, the air conditioner indoor unit 1000 includes an air guiding assembly J1. The air guiding assembly J1 includes: a longitudinal guide vane 130 and a transverse guide vane 110. The longitudinal guide vane 130 is arranged at the first air outlet A21 and is used for guiding air in the left-right direction. In this way, the air at the second air outlet A22 can be guided by the longitudinal guide vane 130, so as to send the air into the room.

[0184] The transverse guide vane 110 is arranged on the front side of the longitudinal guide vane 130 and is used for guiding air in the up-and-down direction. In this way, the transverse guide vane 110 can be used to guide the air sent out from the first air outlet A21 and the second air outlet A22 at the same time, expand the range of air diversion, reduce the occupied space of the air guide component J1, thereby improving the air supply effect of the air guide component J1 and enhancing the user experience.

[0185] In some embodiments, as Figure 3 and Figure 24 shown, a heat exchanger B is provided in the housing A. The heat exchanger B is arranged at the rear side in the main body A6. An air inlet grille M is provided at the rear side of the heat exchanger B. The air inlet grille M is fitted on the rear side of the main body A6 and wraps the heat exchanger B in the housing A. Air enters the housing A from the air inlet grille M, and after heat exchange by the heat exchanger B, a part of the air flows outwards from the front air outlet A2 of the front panel A8 and the air outlet grille L, and another part blows upwards through a predetermined gap A71. The front air outlet A2 and the predetermined gap A71 improve the air outlet effect of the air conditioner.

[0186] Optionally, as Figure 5 shown, a chamfer A61 is provided at the top of the open opening A7, which can not only reduce sharp changes and improve safety, but also play a certain role in guiding air. For example, when the indoor unit 1000 of the air conditioner blows air outwards through the open opening A7, the flow velocity at this position is large and the pressure is small when the air passes through the chamfer A61, and the air at this position will blow outwards along the chamfer A61, so that the air passing through the open opening A7 blows outwards in a flared shape, thereby expanding the blowing range, avoiding wind concentration, and also improving the blowing comfort.

[0187] In some embodiments, as Figures 16 - 18 shown, the indoor unit 1000 of the air conditioner includes: a housing A, an air outlet frame F, and a guide ring G.

[0188] An air inlet A1 and a front air outlet A2 are provided on the housing A. That is, the air entering from the air inlet A1 can flow out from the front air outlet A2.

[0189] The air outlet frame F is arranged in the housing A. The air outlet frame F includes a left side plate F2 and a right side plate F3. The left side plate F2 and the right side plate F3 are arranged at intervals in the left-right direction. 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 in the left-right direction to form a flow channel for air flow, playing a role in guiding air. 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, playing a role of limiting and fixing.

[0190] The air guide ring G is arranged inside the air outlet frame F. A first sub-air duct A51 extending vertically is defined between the left side wall of the air guide ring G and the left side plate F2, and a second sub-air duct A52 extending vertically is defined between the right side wall of the air guide ring G and the right side plate F3. In this way, the air entering from the air inlet A1 can flow through the inside of the air guide ring G, or can flow through the first sub-air duct A51 and the second sub-air duct A52 extending vertically formed between the left and right side plates F3 and the air guide ring G respectively. There are multiple diversion branches, which is beneficial to expanding the air supply range and improving the air supply effect. That is, by defining the first sub-air duct A51 extending vertically between the left side wall of the air guide ring G and the left side plate F2, and the second sub-air duct A52 extending vertically between the right side wall of the air guide ring G and the right side plate F3, left and right branches with upward and downward flows are formed between the left and right side plates F3 and the air guide ring G, which is beneficial to expanding the air supply range, improving the air supply effect, and enhancing the user experience.

[0191] In some embodiments, as Figure 16 and Figure 17 shown, the front air outlet A2 is located on the front side of the air guide ring G. The inner cavity of the air guide ring G is respectively communicated with the air inlet A1 and the front air outlet A2 to ensure that a part of the air sent from the air inlet A1 can enter the front air outlet A2 through the diversion of the inner cavity of the air guide ring G.

[0192] Specifically, as Figure 16 and Figure 17 shown, the air conditioner indoor unit 1000 further includes: a first fan D and a second fan E. The first fan D is arranged inside the air guide ring G to drive the air flow to flow from the air inlet A1 towards the front air outlet A2. The second fan E is arranged inside the housing A. 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 air guide ring G to drive the air flow to flow from the air inlet A1 towards the front air outlet A2, and to drive the air flow to flow from the air inlet A1 through the first sub-air duct A51 and the second sub-air duct A52 and then towards the third air outlet A3.

[0193] It can be understood that the air sent from the air inlet A1 can be inhaled by the first fan D and led out from the front air outlet A2. The air sent from the air inlet A1 can also be inhaled by the second fan E, and the air flow is driven to flow through the first sub-air duct A51 and the second sub-air duct A52 and then towards the front air outlet A2 and the third air outlet A3. In this way, the air at the air inlet A1 can be diverted by multiple fans, increasing the range of air flow, thereby improving the air supply effect of the air conditioner indoor unit 1000.

[0194] In some embodiments, as Figure 4As shown, the first sub-air duct A51 and the second sub-air duct A52 are symmetrically arranged with respect to the guide ring G. The minimum width of the first sub-air duct A51 and the second sub-air duct A52 is W1, and W1 satisfies: 20mm ≤ W1 ≤ 60mm. It can be understood that the first sub-air duct A51 and the second sub-air duct A52 are symmetrically arranged with respect to the guide ring G to serve as the flow channels for the air driven by the second fan E. If the widths of the first sub-air duct A51 and the second sub-air duct A52 are too small, it is not conducive to the rapid delivery of the air after heat exchange inside the air conditioner, which easily causes the air to accumulate inside the housing, resulting in an increase in the internal pressure and potential safety hazards. Therefore, the minimum width of the first sub-air duct A51 and the second sub-air duct A52 is set to 20mm ≤ W1 ≤ 60mm, which can ensure that within this range, the air flows better through the first sub-air duct A51 and the second sub-air duct A52.

[0195] In some alternative embodiments, as Figure 17 shown, a volute I is provided inside the housing A, the second fan E is arranged inside the volute I, the volute I has a volute inlet I1 and a volute outlet I2, the volute inlet I1 is opposite to the air inlet A1, and the volute outlet I2 is opposite to the guide ring G. In this way, the second fan E can suck the air at the air inlet A1 and flow it into the volute inlet I1, and the air flows toward the guide ring G after being sent out from the volute outlet I2.

[0196] Specifically, as Figure 17 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 air sent out from the volute outlet I2 can be blocked by the guide ring G, so as to be diverted 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 air sent out from the volute outlet I2 can also directly flow into the first sub-air duct A51 and the second sub-air duct A52, which is beneficial to the rapid passage of the air flow, thereby improving the air outlet efficiency of the indoor unit 1000 of the air conditioner.

[0197] In some embodiments, as Figure 8 and Figure 9 shown, the indoor unit 1000 of the air conditioner further includes longitudinal guide vanes 130. The longitudinal guide vanes 130 are arranged between the housing A and the blocking member H. Each longitudinal guide vane 130 includes a plurality of parts extending in the up and down direction, and the plurality of longitudinal guide vanes 130 are arranged side by side in the left and right direction. Among them, 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 and right direction, so as to further adjust the flow direction of the air flow and make the air outlet more uniform.

[0198] Specifically, as Figure 8 and Figure 9As shown, the air conditioner indoor unit 1000 further includes a lateral guide vane 110. The lateral guide vane 110 is disposed within the housing A and in front of the longitudinal guide vane 130. The lateral guide vane 110 extends in the left-right direction and includes a plurality of them. The plurality of lateral guide vanes 110 are arranged side by side in the up-down direction. In this way, the longitudinal guide vane 130 can be used to guide the air flow sent out from the front air outlet A2 in the up-down direction to further adjust the air flow direction and make the air outlet more uniform.

[0199] In some embodiments, the air conditioner indoor unit 1000 further includes: as Figure 2 and Figure 3 shown, a third air guide assembly J13. The third air guide assembly J13 includes a plurality of first air guide plates J131. The first air guide plates J131 are rotatably arranged at the third air outlet A3 to open or close the third air outlet A3. The rotation axis of the first air guide plates J131 extends along the width direction of the housing A. In this way, the first air guide plates J131 can rotate in the up-down direction, so that the air sent out from the third air outlet A3 can be guided by the plurality of first air guide plates J131 to adjust the air direction, increase the air outlet range, and make the air outlet more uniform. At the same time, when the first air guide plates J131 are closed, they also have a dust-proof function and can protect the cleanliness inside the air conditioner in the non-working state.

[0200] Specifically, as Figure 2 and Figure 3 shown, the third air guide assembly J13 further includes a second air guide plate. The second air guide plate is rotatably arranged at the third air outlet A3. Along the air flow direction, the second air guide plate is located upstream of the first air guide plates J131. 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 from the third air outlet A3 can be jointly guided by the first air guide plates J131 and the second air guide plate, further increasing the air outlet range and enhancing the air outlet effect.

[0201] In some embodiments, as Figures 2 - 7 shown, the air conditioner indoor unit 1000 includes: a housing A and a blocking member H.

[0202] 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 communicating the air inlet A1 and the second air outlet A22 is defined within the housing A. The second air duct A5 extends in the vertical direction. That is, the air at the air inlet A1 can flow out of the second air outlet A22 along the second air duct A5.

[0203] The blocking member H is disposed in the second air duct A5. The blocking member H is configured to block the air flow in the second air duct A5, so as to form a positive pressure region upstream of the blocking member H. The air in the positive pressure region can flow out from the second air outlet A22. That is to say, the air flow in the second air duct A5 flows towards the blocking member H to form a positive pressure region. Since the air in the positive pressure region will automatically flow towards the normal pressure region, the air flow in the second air duct A5 can flow out from the second air outlet A22. That is, by setting the blocking member H to block the air flow in the second air duct A5 to form a positive pressure region, the air flow in the second air duct A5 can change direction and flow out from the second air outlet A22, thereby improving the air supply efficiency effect.

[0204] According to an embodiment of the present invention, as Figure 4 shown, the blocking member H includes: a lower blocking plate H1. The cross-section of the lower blocking plate H1 in the front-rear direction is arc-shaped, and the lower blocking plate H1 protrudes downward and extends in the front-rear direction. In this way, the front-rear extending lower blocking member H can block the air flow from the second air duct A5. Since the cross-section of the lower blocking plate H1 in the front-rear direction is arc-shaped and protrudes downward, the lower blocking plate H1 can effectively introduce the air flow in 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 is beneficial to the rapid diversion of the air and increases the air volume entering.

[0205] Specifically, as Figure 2 and Figure 4 shown, one end of the lower blocking plate H1 is in contact with the inner wall of the second air duct A5, and the other end of the lower blocking plate H1 is spaced apart from the inner wall of the second air duct A5. A second sub-air duct A52 is defined between the other end of the lower blocking plate and the second air duct A5. In this way, one end of the lower blocking plate H1 in contact with the inner wall of the second air duct A5 can block the air flow from the second air duct A5, and the other end of the blocking plate spaced apart from the inner wall of the second air duct A5 can guide the air flow to flow in the second air duct A5.

[0206] Furthermore, as Figure 4 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. 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 air flow from the other end of the lower blocking plate H1 to flow upward along the longitudinal blocking plate H3.

[0207] In some alternative embodiments, as Figure 3 and Figure 4As shown in the figure, the longitudinal baffle H3 has an arc-shaped cross-section in the front-back direction, and the longitudinal baffle H3 protrudes towards the second air duct A5. In this way, the longitudinal baffle protruding towards the second air duct A5 can block the air flow from the lower baffle H1, making it flow along the second sub-air duct A52, and the arc-shaped setting will be conducive to the rapid diversion of the wind and increase the incoming air volume.

[0208] In some alternative embodiments, the blocking member H further includes: an upper baffle H2. The two ends of the upper baffle H2 are respectively connected to the inner wall of the longitudinal baffle H3 and the second air duct A5. Among them, the lower baffle H1, the longitudinal baffle H3 and the upper baffle H2 jointly define a first air duct A4 that penetrates in the front-back direction. On the one hand, the upper baffle H2, the lower baffle H1, and the total baffle jointly define a first air duct A4 that penetrates in the front-back direction, so that the air flow can flow along the first air duct A4. On the other hand, the upper baffle H2, the lower baffle H1, and the longitudinal baffle can also jointly define a second air duct A5 that penetrates up and down with the housing A.

[0209] Specifically, as Figure 4 shown, the upper baffle H2 has an arc-shaped cross-section in the front-back direction and protrudes upwards. The upper baffle H2 and the longitudinal baffle H3 are in arc transition to facilitate the rapid passage of the air flow and reduce the energy loss of the air flow.

[0210] In some embodiments, as Figure 4 shown, the air conditioner indoor unit 1000 further includes an air outlet frame F. The air outlet frame F is arranged inside the housing A, and the blocking member H is arranged inside the air outlet frame F. Among them, the first sub-air duct A51 and the second sub-air duct A52 are jointly defined between the outer wall of the blocking member H and the inner wall of the air outlet frame F. That is, the air sent by the second air duct A5 will flow along the first sub-air duct A51 and the second sub-air duct A52 between the outer wall of the blocking 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 the over-concentration of the wind force.

[0211] In some embodiments, as Figures 2 - 7 shown, the air conditioner indoor unit 1000 includes: a housing A and a blocking member H.

[0212] 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 communicating the air inlet A1 and the second air outlet A22 is defined inside the housing A, and the second air duct A5 extends in the vertical direction. That is, the air at the air inlet A1 can flow out of the second air outlet A22 along the second air duct A5.

[0213] The blocking member H is disposed 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 that are spaced apart 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 communicated with both 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 converges in the confluence area, it flows out of the second air outlet A22 along the direction of the blocking member H. In this way, when the air at the air inlet A1 flows along the second air duct A5, the blocking member H can divide the air flow 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. After converging in the confluence area, it flows out of the second air outlet A22 along the extending direction of the blocking member H.

[0214] 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 air flow in the second air duct A5 and discharge it toward the second air outlet A22. As a result, the air flow can flow in the first channel and the second channel, effectively splitting the air flow and making the air outlet more uniform. That is, by arranging 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 air flow in the second air duct A5 is effectively split and the air outlet is more uniform, improving the user experience.

[0215] In some embodiments, such as 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, introduce the air flow into the first sub-air duct A51 and the second sub-air duct A52, and after the air flowing through the first sub-air duct A51 and the second sub-air duct A52 converges in the confluence area, the blocking member H sends it forward along 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 air flow, and when used for this function, it is also called the guide ring G.

[0216] In some embodiments, such as Figure 3 As shown, a first air duct A4 is formed in the inner cavity of the blocking member H, a first fan D is provided 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, where the first air outlet A21 is located on the front side of the first sub-air duct A51, the second sub-air duct A52, and the confluence area. In this way, the air at the air inlet A1 inhaled by the first fan D can flow forward along the first air duct A4 and flow toward 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 through multiple channels, which is beneficial to further improving the range of air flow and thus improving the air supply effect of the air conditioner indoor unit 1000.

[0217] Optionally, such as Figure 4As shown, in the left - right direction, the lower baffle H1 is located in the middle of the housing A. It further includes: a left baffle H31 and a right baffle H32. The left baffle H31 is connected to the left end of the lower baffle H1 and extends upward. A first sub - air duct A51 is defined between the left baffle H31 and the inner wall of the housing A. The right baffle H32 is connected to the right end of the lower baffle H1 and extends upward. A second sub - air duct A52 is defined between the right baffle H32 and the inner wall of the housing A. That is, through the diversion of the lower baffle H1, the air flow will respectively enter the first sub - air duct A51 defined between the left baffle H31 and the inner wall of the housing A and the second sub - air duct A52 defined between the right baffle H32 and the inner wall of the housing A, and flow along the upward - extending direction of the left baffle H31 and the right baffle H32.

[0218] Further, as Figure 4 shown, the cross - sections of the left baffle H31 and the right baffle H32 in the front - back direction are arc - shaped, and the opposite sides of the left baffle H31 and the right baffle H32 are respectively recessed. In this way, the arc - shaped recessed opposite sides of the left baffle H31 and the right baffle H32 can guide the air flow from the lower baffle H1, and the arc - shaped setting is conducive to the rapid diversion of the wind and increases the amount of air entering.

[0219] In some alternative embodiments, as Figure 4 shown, the left baffle H31 and the right baffle H32 are respectively in arc transition with the lower baffle H1 to facilitate the rapid passage of the air flow and reduce the energy loss of the air flow.

[0220] In some alternative embodiments, as Figure 4 shown, the blocking member H further includes: an upper baffle H2. The two ends of the upper baffle H2 are respectively connected to the left baffle H31 and the right baffle H32. Among them, a first air duct A4 that penetrates in the front - back direction is jointly defined among the lower baffle H1, the left baffle H31, the right baffle H32, and the upper baffle H2. On the one hand, a first air duct A4 that penetrates in the front - back direction is jointly defined among the upper baffle H2, the lower baffle H1, the left baffle H31, and the right baffle H32, so that the air flow can flow along the first air duct A4. On the other hand, an upper - lower - penetrating second air duct A5 can also be jointly defined among the upper baffle H2, the lower baffle H1, the left baffle H31, and the right baffle H32 and the air - outlet frame F.

[0221] Specifically, as Figure 4 shown, the cross - section of the upper baffle H2 in the front - back direction is arc - shaped and convex upward. The upper baffle H2 is in arc transition with the left baffle H31 and the right baffle H32 to facilitate the rapid passage of the air flow and reduce the energy loss of the air flow.

[0222] In some embodiments, as Figure 8 andFigure 9 As shown, the air conditioner indoor unit 1000 further includes a first air guiding assembly J11. The first air guiding assembly J11 is disposed between the housing A and the blocking member H. Each first air guiding assembly J11 includes a plurality of longitudinal guide vanes 130 extending in the vertical direction. The plurality of longitudinal guide vanes 130 are arranged in the left-right direction. Among them, the lengths of the plurality of longitudinal guide vanes 130 gradually decrease in the direction from the left and right sides towards 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 air flow and make the air outlet more uniform at the same time.

[0223] In some embodiments, as Figure 8 and Figure 9 shown, it further includes a second air guiding assembly J12. The second air guiding assembly J12 is disposed inside the housing A and in front of the first air guiding assembly J11. The second air guiding 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 vertical direction. In this way, the transverse guide vanes 110 can be used to guide the air flow sent out from the front air outlet A2 in the vertical direction, so as to further adjust the flow direction of the air flow and make the air outlet more uniform at the same time.

[0224] In some embodiments, as Figure 7 shown, the air conditioner indoor unit 1000 further includes a wind guiding cover N. The wind guiding cover N is disposed at the front end of the blocking member H and is configured to guide the air flow passing through it to be sent out in a spiral manner. In this way, the air at the first air outlet A21 can be further guided by the wind guiding cover N. Thus, the wind inhaled by the motor D2 is further concentrated and is not likely to disperse at the first air outlet A21, enhancing the air outlet intensity and air volume at the first air outlet A21. At the same time, it can also increase the air outlet volume and air supply range of the air conditioner indoor unit 1000.

[0225] In some embodiments, as Figures 16 - 18 shown, the air conditioner indoor unit 1000 includes: a housing A, a flow guiding ring G, and an axial flow fan D1.

[0226] An air inlet A1 and a front air outlet A2 are formed on the housing A. The flow guiding ring G is disposed inside the housing A, and a first air duct A4 for communicating the air inlet A1 and the front air outlet A2 is defined inside the flow guiding ring G. The plane where the rear end of the flow guiding ring G is located is the air guiding surface G1. In this way, the air flowing in from the air inlet A1 can flow towards the front air outlet A2 under the guidance of the flow guiding ring.

[0227] The axial flow impeller D1 is rotatably arranged in the first air duct A4, and the rear tip D12 of the axial flow impeller D1 extends backward beyond the air guiding surface G1. In this way, the distance between the axial flow impeller D1 and the air inlet A1 can be shortened, the air suction range of the axial flow impeller D1 can be expanded, the air volume sucked by the axial flow impeller D1 can be increased, and thus the air supply effect of the air conditioner indoor unit 1000 can be improved. At the same time, the internal structure of the air conditioner indoor unit 1000 is more compact, which is beneficial to the miniaturization of the air conditioner indoor unit 1000. That is, by making the rear tip D12 of the axial flow impeller D1 extend backward beyond the air guiding surface G1, the distance between the axial flow impeller D1 and the air inlet A1 can be shortened, the air suction range of the axial flow impeller D1 can be expanded, the air volume sucked by the axial flow impeller D1 can be increased, and the air supply effect of the air conditioner indoor unit 1000 can be further improved. At the same time, the internal structure of the air conditioner indoor unit 1000 is more compact, which is beneficial to the miniaturization of the air conditioner indoor unit 1000.

[0228] In some embodiments, such as Figure 17 and 18 shown, the range of the distance L1 by which the rear tip D12 of the axial flow impeller D1 extends backward beyond the air guiding surface G1 is 1 mm to 50 mm. That is, the distance by which the rear tip D12 of the axial flow impeller D1 extends backward beyond the air guiding surface G1 is limited within a reasonable range. In this way, during the rotation of the axial flow impeller D1, on the premise of protecting the safety of the rear tip D12, the distance between the axial flow impeller D1 and the air inlet A1 can be shortened, and thus the air suction range of the axial flow impeller D1 can be expanded. (1) In some embodiments, the indoor air conditioner further includes: a heat exchanger B and a wind deflector N.

[0229] The heat exchanger B is placed in the housing A and is located between the air inlet A1 and the front air outlet A2, and the axial flow impeller D1 is located in front of the heat exchanger B. In this way, the axial flow impeller D1 and the heat exchanger B are arranged staggered in the horizontal direction front and back, which can make the structural arrangement in the housing A reasonable, the layout compact, make full use of the space in the housing A, and is beneficial to reducing the volume of the entire housing A.

[0230] There is a first predetermined distance L2 between the rear tip D12 of the axial flow impeller D1 and the heat exchanger B. In this way, a certain distance is maintained between the rear tip D12 of the axial flow impeller D1 and the heat exchanger B, and during the rotation of the axial flow impeller D1, the safety of the rear tip D12 can be protected.

[0231] The wind deflector N is arranged on the air guiding ring G and covers the front end of the first air duct A4. It can be understood that arranging the wind deflector N on the air guiding ring G can play a role in guiding the air flow;

[0232] There is a second predetermined distance L3 between the front tip D11 of the axial flow impeller D1 and the wind deflector N. In this way, a certain distance is maintained between the front tip D11 of the axial flow impeller D1 and the wind deflector N, and during the rotation of the axial flow impeller D1, the safety of the front tip D11 can be protected.

[0233] Specifically, as Figure 17 shown, the first predetermined distance L2 between the rear tip D12 of the axial flow impeller D1 and the heat exchanger B is not less than 18 mm, and the second predetermined distance L3 between the front tip D11 of the axial flow impeller D1 and the air guide cover N is not less than 18 mm. In this way, during the movement of the axial flow impeller D1, the front and rear sharp corners are not likely to interfere with other surrounding components, thus causing damage to the axial flow impeller D1. At the same time, it should be noted here that the first predetermined distance L2 between the rear tip D12 of the axial flow impeller D1 and the heat exchanger B and the second predetermined distance L3 between the front tip D11 of the axial flow impeller D1 and the air guide cover N are not the larger the better. Otherwise, the front-to-back dimension of the entire air conditioner indoor unit 1000 will be too large, occupying a large space and having a large mass.

[0234] It can be understood that designing the first predetermined distance L2 between the rear tip D12 of the axial flow impeller D1 and the heat exchanger B to be not less than 18 mm and the second predetermined distance L3 between the front tip D11 of the axial flow impeller D1 and the air guide cover N to be not less than 18 mm provides a reasonable installation position G2 for the blades of the axial flow fan, which improves the air supply efficiency of the first fan D while ensuring the front and rear safety distances of the axial flow impeller D1.

[0235] In some alternative embodiments, as Figure 17 shown, the radius of the sweeping area of the front tip D11 of the axial flow impeller D1 is equal to the radius of the sweeping area of the rear tip D12 of the axial flow impeller D1. That is to say, the outer radial ends of the front tip D11 and the rear tip D12 are located on the same vertical plane, which can ensure the uniformity of air flow

[0236] Specifically, the radius of the sweeping area of the front tip D11 of the axial flow impeller D1 and the radius of the sweeping area of the rear tip D12 of the axial flow impeller D1 are both 125 mm - 130 mm. In a specific embodiment, the radius of the sweeping area of the front tip D11 of the axial flow impeller D1 and the radius of the sweeping area of the rear tip D12 of the axial flow impeller D1 can both be 128 mm, which can increase the area of the sweeping areas of the front tip D11 and the rear tip D12 as much as possible, being beneficial to the air supply efficiency of the first fan D and also beneficial to shortening the length of the first air duct A4.

[0237] In some alternative embodiments, as Figure 17As 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.

[0238] In some embodiments, Figure 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.

[0239] In some optional embodiments, such as Figure 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.

[0240] Specifically, Figure 16 As 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.

[0241] In other embodiments of the present invention, Figures 7 - 24As shown in the figure, the air conditioner indoor unit 1000 includes: a guide ring G, a first fan D, and a wind guide cover N. The guide ring G is formed with a first air inlet and a first air outlet A21. The first fan D is disposed inside the guide ring G and is used to drive air to flow out of the first air outlet A21 from the first air inlet. The wind guide cover N is disposed at the first air outlet A21 of the guide ring G, and the wind guide cover N is provided with stationary vanes N1 through which the air passing through the wind guide cover N can rotate and blow out at a predetermined angle.

[0242] It can be understood that the first fan D can suck the air at the first air inlet, and guide the air flow to the first air outlet A21 through the guide ring. At this time, the wind guide cover N disposed at the first air outlet A21 can further direct the flowing air. At the same time, the stationary vanes N1 can make the air of the wind guide cover N rotate and blow out at a predetermined angle. Thus, the air sucked by the motor D2 is further concentrated and is not easily scattered when passing through the first air outlet A21, enhancing the air outlet intensity and air volume of the first air outlet A21, and at the same time, it can also increase the air outlet volume and air supply range of the air conditioner indoor unit 1000.

[0243] In some embodiments, as Figure 19 shown, the stationary vanes N1 are movably disposed on the wind guide cover N between a first position and a second position. Wherein, at the first position, the stationary vanes N1 open the first air outlet A21, and at the second position, the stationary vanes N1 close the first air outlet A21. In this way, when the stationary vanes N1 open the first air outlet A21, the air at the first air inlet can flow through the wind guide cover N and flow out of the first air outlet A21, and the wind guide cover N can guide the air flow direction to expand the air outlet range. When the stationary vanes N1 close the first air outlet A21, the stationary vanes N1 can also block dust and other particles in the external air, improving the cleanliness inside the air conditioner indoor unit 1000.

[0244] Specifically, as Figure 20 shown, the wind guide cover N includes: a swirl mounting frame N2 and a vane drive plate N3. The swirl mounting frame N2 is fixed at the first air outlet A21. The swirl mounting frame N2 includes an outer ring N21 and a fixing ring N22 located in the middle of the outer ring N21. The vane drive plate N3 is disposed on the swirl mounting frame N2 and is rotatable around the outer ring N21. One end of the stationary vane N1 is connected to the fixing ring N22 and is rotatable in the radial direction relative to the fixing ring N22. The other end of the stationary vane N1 is connected to the vane drive plate N3 to drive the movement of the stationary vane N1 between the first position and the second position. That is to say, one end of the stationary vane N1 is connected to the fixing ring N22, so that the swirl mounting frame N2 can limit the position of the stationary vane N1. At the same time, one end of the stationary vane N1 is rotatable in the radial direction relative to the fixing ring N22. In this way, when the vane drive plate N3 drives the other end of the stationary vane N1 to rotate, one end of the stationary vane N1 can rotate radially relative to the outer ring N21 of the swirl mounting frame N2 following the other end of the stationary vane N1.

[0245] Further, as Figure 20 shown, an installation hole N221 is provided on the circumferential wall of the fixed ring N22, and one end of the stationary blade N1 passes through the installation hole N221 and is rotatable within the installation hole N221. That is, the provision of the installation hole N221 rotatably connects one end of the stationary blade N1 to the fixed ring N22, so that one end of the stationary blade N1 can rotate relative to the inside of the installation hole N221.

[0246] (4) In some alternative embodiments, as Figure 20 shown, the blade drive plate N3 is sleeved outside the outer ring N21, wherein an installation groove N212 is provided on the outer ring N21, and the stationary blade N1 is supported within the installation groove N212. It can be understood that the blade drive plate N3 is sleeved outside the outer ring N21, so that the outer ring N21 can play a role in limiting the blade drive plate N3. The stationary blade N1 is supported within the installation groove N212 provided on the outer ring N21, and the installation groove N212 can play a role in limiting 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.

[0247] In some alternative embodiments, the stationary blade N1 includes: a blade N10 and a piston shaft N12. One end of the blade N10 is connected to the fixed ring N22, and a sleeve N101 is provided at the other end of the blade N10. 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 telescopic within the sleeve N101 to drive the blade N10 to move between a first position and a second position. That is, the first end of the piston shaft N12 rotates relative to the blade drive plate N3 under the drive of the blade drive plate N3, so that the second end of the piston shaft N12 is telescopic to drive the other end of the blade N10 to rotate, and one end of the blade N10 rotates relative to the fixed ring N22 following the other end of the blade N10, and thus the entire blade N10 can move between a first position and a second position.

[0248] Specifically, as Figure 21 shown, the first end of the piston shaft N12 is connected to the blade drive plate N3 through a ball joint. It can be understood that the provision of the ball joint makes the rotation between the first end of the piston shaft N12 and the blade drive plate N3 more flexible and can expand the air guiding range of the blade N10.

[0249] In some alternative embodiments, as Figure 22 and 23As shown, a guide groove N31 extending perpendicular to the blade driving plate N3 is provided on the blade driving plate N3. The air conditioner indoor unit 1000 further includes a driving plate driving device P, and the driving plate driving device P includes: a driving plate motor P1 and a crank P2. One end of the crank P2 is connected to the motor shaft P12 of the driving plate motor. The other end of the crank P2 can reciprocate within the guide groove N31, and one end and the other end of the crank P2 are not coaxial. That is, in the working state of the driving plate motor P1, the motor shaft P12 of the driving plate motor

[0250] drives one end of the crank P2 to rotate relatively. Since one end and the other end of the crank P2 are not coaxial, the other end of the crank P2 can move within the guide groove N31, thereby driving the blade driving plate N3 to rotate relatively.

[0251] In some alternative embodiments, such as Figure 20 As shown, the air guide cover N further includes: a driving bottom plate N4. The driving bottom plate N4 is sleeved outside the outer ring N21. The blade driving plate N3 is arranged above the driving bottom plate N4. A positioning structure N41 is provided between the driving bottom plate N4 and the blade driving plate N3 to enable the blade driving plate N3 and the driving bottom plate N4 to rotate synchronously. In this way, the driving bottom plate N4 can fix the blade driving plate N3, increasing the rigidity of the blade driving plate N3, so that the rotation of the blade driving plate N3 is more stable.

[0252] Optionally, the positioning structure N41 includes a positioning post N411 and a positioning sleeve N412, and the positioning post N411 and the positioning sleeve N412 are sleeved with each other. On the one hand, the arrangement of the positioning post N411 and the positioning sleeve N412 can act as a reinforcing rib, which can further improve the rigidity of the driving bottom plate N4 and the blade driving plate N3. On the other hand, the installation of the positioning post N411 and the positioning sleeve N412 is simple and convenient for operation.

[0253] Specifically, as Figure 20 shown, through holes are respectively provided on the driving bottom plate N4 and the blade driving plate N3 and are correspondingly arranged. Such an arrangement of the through holes provides a clearance space for the connection between the driving bottom plate N4 and the blade driving plate N3, enabling the driving bottom plate N4 and the blade driving plate N3 to be connected by a connecting member. At the same time, the driving bottom plate N4 has a limiting and fixing effect on the blade driving plate N3, improving the smoothness of the relative movement of the blade driving plate N3.

[0254] In some alternative embodiments, such as Figure 20As shown in the figure, the air guide cover N further includes: a swirl vane pressing plate N5. The swirl vane pressing plate N5 is fixed on the swirl mounting bracket N2, and the stationary vane N1 is arranged between the swirl vane pressing plate N5 and the swirl mounting bracket N2. In this way, during the rotation of the stationary vane N1, the swirl vane pressing plate N5 and the swirl mounting bracket N2 on both sides of the stationary vane N1 can reduce the risk of the stationary vane N1 touching fingers and improve the safety of the air conditioner indoor unit 1000.

[0255] In some embodiments, as Figure 20 shown, the stationary vane N1 includes a plurality of stationary vanes N1 arranged circumferentially around the fixing ring N22. It can be understood that the arrangement of the plurality of stationary vanes N1 can reduce the design length of a single stationary vane N1 and increase the design flexibility of the stationary vane N1. At the same time, in order to ensure the air guiding effect of the stationary vane N1 at the first air outlet A21, a plurality of stationary vanes N1 are arranged circumferentially around the fixing ring N22 so that the distance between adjacent stationary vanes N1 in the circumferential direction is appropriate to ensure sufficient air guiding effect and small wind resistance.

[0256] In some other embodiments of the present invention, as Figure 20 shown, a plurality of mounting lugs N6 are provided on the air guide cover N, and a plurality of mounting positions G2 are provided on the outer wall of the guide vane ring G. The plurality of mounting lugs N6 are installed in one-to-one correspondence with the plurality of mounting positions G2. The mounting lugs N6 provide specific mounting positions G2 for fixing the air guide cover N and the guide vane ring, so that the air guide cover N is connected to the guide vane ring G. At the same time, the installation between the mounting lugs N6 and the mounting positions is simple and easy to operate.

[0257] In some embodiments, as Figure 20 shown, the air guide cover N includes an inner ring mounting ring N7 and an outer ring mounting ring N8 wound around the outside of the inner ring mounting ring N7. Both ends of the plurality of stationary vanes 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 vanes N1, so that the plurality of stationary vanes N1 can be stably connected to the inner ring mounting ring N7 and the outer ring mounting ring N8, and the smoothness of the movement of the plurality of stationary vanes N1 is improved.

[0258] In some embodiments, as Figure 20 shown, the plurality of stationary vanes 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 for air circulation. The stationary vanes N1 are radially arranged between the inner ring mounting ring N7 and the outer ring mounting ring N8, and can guide and further gather the flowing air within the maximum range and output it to the first air outlet A21.

[0259] In some embodiments, as Figure 19 and Figure 20As shown, the cross-section of the stationary blade N1 within the air guide cover N accounts for 5% to 15% of the difference between the cross-section of the air guide cover N and the cross-section of the inner ring mounting ring N7. That is, the stationary blade N1 disposed between the flow guide ring G and the inner ring mounting ring N7 occupies part of the air flow space. To ensure the strength of the air guide cover N itself and its wind guiding property, the cross-section of the stationary blade N1 within the air guide cover N accounting for the difference between the cross-section of the air 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 stationary blade N1 within the air guide cover N accounts for 5% to 15% of the difference between the cross-section of the air guide cover N and the cross-section of the inner ring mounting ring N7, the air guide cover N has sufficient structural strength and a good wind guiding effect.
