[0050] Figure 1is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present application, as shown in Figure 1 , and referring to Figures 2 to 7 , the embodiment of the present application provides an air conditioner indoor unit with two side air outlets, which comprises a vertically arranged shell 100 and a cross-flow fan 700, and a supply air passage 200, a first side air duct 300 and a second side air duct 400 are arranged in the shell. The cross-flow fan 700 is arranged in the supply air passage. The shell 100 has a front wall 110, a first side wall 120 and a second side wall 130. The front wall is provided with a front air outlet 140 extending in the vertical direction, and the front air outlet 140 is the outlet of the supply air passage 200. The first side wall 120 is connected to the front wall 110, and the connection between the first side wall and the front wall 110 is a first edge 111. A first side air outlet 150 is arranged on the first side wall 120, and the ratio of the distance H1 from the front edge of the first side air outlet to the first edge 111 to the diameter of the cross-flow fan 700 is 0.08 to 0.24. The first side air outlet 150 is communicated with the supply air passage 200 through the first side air duct 300. The second side wall 130 is connected to the front wall 110, and the connection between the second side wall and the front wall 110 is a second edge 112. A second side air outlet 160 is arranged on the second side wall 130, and the ratio of the distance H2 from the front edge of the second side air outlet to the second edge 112 to the diameter of the cross-flow fan is 0.08 to 0.24. The second side air outlet 160 is communicated with the supply air passage 200 through the second side air duct 400.

[0051] In the air conditioner indoor unit of the embodiment of the present application, the airflow passes through the supply air passage 200, part of the airflow flows out from the front air outlet 140, part of the airflow flows out from the first side air outlet 150 through the first side air duct 300, and the remaining part of the airflow blows out from the second side air outlet 160 through the second side air duct 400. The distance H1 from the front edge of the first side air outlet to the first edge and the distance H2 from the front edge of the second side air outlet to the second edge are limited, so that the first side air outlet 150 and the second side air outlet 160 on both sides of the shell 100 can effectively increase the horizontal air supply angle, and the user experience is improved. The above-mentioned arrangement is also beneficial to ensure that the interference between the air outlets is small when the three air outlets blow air at the same time, and avoids the situation that the air outlets of the first side air outlet 150 and the second side air outlet 160 are deviated to the central air outlet under the suction effect of the air outlet of the front air outlet 140 of the front wall 110, resulting in the decrease of the air outlet included angle.

[0052] In some embodiments of the present application, preferably, H1 is equal to H2, and H1 and H2 are both between 10 mm and 15 mm.

[0053] In some embodiments of the present application, as shown in Figure 1 and Figure 2As shown, the indoor unit of the air conditioner further comprises a volute 500 and a volute tongue 600 for defining the air supply passage 200. The first side wall 120 is adjacent to the volute tongue 600, and the second side wall 130 is adjacent to the volute 500. The volute tongue 600 comprises a first air duct section, and a surface of the first air duct section for defining the air supply passage 200 is a first arc surface 610 in a concave shape, a front end of the first arc surface 610 being connected with a rear wall of the first side air duct 300. The front end of the first arc surface 610 is obliquely in front of a rear end of the first arc surface 610, and the rear end of the first arc surface 610 is adjacent to a first reference surface. The first reference surface is a vertical plane extending along the front-rear direction and is at a position in the middle of the inlet end edge of the rear wall of the first side air duct 300 and the inlet end edge of the rear wall of the second side air duct 400 in the transverse direction. The volute 500 comprises a second air duct section 510, and a surface of the second air duct section 510 for defining the air supply passage 200 is connected with the rear wall of the second side air duct 400 through a second arc surface 520. A front end of the second arc surface 520 is obliquely in front of a rear end of the second arc surface 520, the rear end of the second arc surface 520 is adjacent to the first reference surface, and a vertical distance between the rear end of the second arc surface 520 and the first reference surface is greater than a minimum distance between the second arc surface 520 and the first reference surface.

[0054] Most of the air blown out from the cross-flow fan 700 is deviated to the volute 500, and the arrangement of the first arc surface 610 and the second air duct section 510 causes a part of the air flow close to the volute 500 to be blown to the first arc surface 610 and then blown out forward, which is beneficial to the uniformity of the air outflow in the entire air supply passage 200.

[0055] Further, in some embodiments of the present application, as shown in Figure 2 The ratio between the radius R2 of the first arc surface 610 and the diameter of the cross-flow fan 700 is 0.63 to 0.71, and the central angle of the first arc surface 610 is 40° to 50°.

[0056] In some embodiments of the present application, the radius R1 of the second arc surface is greater than 4 mm and less than 20 mm, the ratio between the radius of the second arc surface and the radius of the first arc surface is 0.20 to 0.25, and the central angle of the second arc surface is 100° to 110°. The above-mentioned limitation on the second arc surface can make the flow resistance of the air flow entering the second side air duct 400 through the air supply passage 200 smaller.

[0057] In some embodiments of the utility model, the upper edge of the front air outlet 140, the upper edge of the first side air outlet 150 and the upper edge of the second side air outlet 160 are flush. The lower edge of the front air outlet 140, the lower edge of the first side air outlet 150 and the lower edge of the second side air outlet 160 are flush. The ratio between the width W6 of the front air outlet 140 and the diameter of the cross-flow impeller 700 is 1.29 to 1.42, which ensures the air volume of the front air outlet 140. Preferably, the ratio between the width W6 of the front air outlet 140 and the diameter of the cross-flow impeller 700 is 1.35.

[0058] In some embodiments of the utility model, the width W1 of the first side air outlet 150 and the second side air outlet 160 is equal, which makes the appearance of the air conditioner indoor unit consistent and more beautiful.

[0059] In some embodiments of the utility model, as shown in Figures 1 to 7 The inlet end edge of the front wall of the first side air duct 300 is a first inlet edge 330, the inlet end edge of the front wall of the second side air duct is a second inlet edge 430, the inlet end edge of the rear wall of the first side air duct is a third inlet edge 320, and the inlet end edge of the rear wall of the second side air duct is a fourth inlet edge 420. The rear edge of the first side air outlet is on the lateral side of the third inlet edge 320, and the front edge of the first side air outlet is obliquely in front of the first inlet edge 330. The first inlet edge 330 is obliquely in front of the third inlet edge 320 close to the first side wall. The rear edge of the second side air outlet is obliquely in front of the fourth inlet edge 420, and the front edge of the second side air outlet is obliquely in front of the second inlet edge 430. The second inlet edge 430 is obliquely in front of the fourth inlet edge 420 close to the second side wall. That is, the first side air duct 300 is inclined obliquely forward from back to front, and is more conducive to the entry of the air outlet through the air supply channel 200. The second side air duct 400 is inclined obliquely forward from back to front, and is more conducive to the entry of the air outlet through the air supply channel 200.

[0060] In some embodiments of the utility model, as shown in Figures 1 to 7 The ratio of the vertical distance between the first inlet edge 330 and the first reference surface to the distance between the second inlet edge 430 and the first reference surface is 0.96 to 0.99. That is, the distance between the first inlet edge 330 and the first reference surface is slightly smaller than the distance between the second inlet edge 430 and the first reference surface. This arrangement can make the amount of air outlet of the air supply channel 200 entering the first side air duct 300 and the second side air duct 400 differ little, thereby ensuring that the air volume of the first side air outlet 150 and the second side air outlet 160 differs little, and ensuring that the air outlets on both sides of the shell 100 are uniform.

[0061] In some embodiments of the utility model, as shown in Figures 1 to 2As shown, the rear wall of the first side air duct 300 is a vertical plane perpendicular to the first reference plane, and the front wall of the first side air duct 300 is an inclined plane. The included angle between the front wall of the first side air duct 300 and the second reference plane is an acute angle. That is, along the flow direction of the airflow, the first side air duct 300 gradually widens, so that the first side air duct 300 is a diffuser section, which improves the static pressure of the airflow and helps to improve the wind speed of the first side air duct 300, so that the airflow blown out of the first side air outlet 150 can blow forward for a longer distance, and users farther away from the air conditioner indoor unit can be taken care of.

[0062] In some embodiments of the present application, as shown in Figures 1 to 2 As shown, the rear wall of the second side air duct and the front wall of the second side air duct are both inclined planes. The included angle between the rear wall of the second side air duct and the lateral side of the second reference plane is a first included angle, which is an acute angle. The included angle between the front wall of the second side air duct and the lateral side of the second reference plane is a second included angle, which is an acute angle, and the second included angle is smaller than the first included angle. That is, along the flow direction of the airflow, the second side air duct 400 gradually narrows.

[0063] In some embodiments of the present application, as shown in Figures 1 to 2 As shown, the ratio of the distance W7 from the first inlet edge to the third reference plane to the diameter of the cross-flow fan wheel is 0.86 to 0.98. The ratio of the distance from the second inlet edge to the third reference plane to the diameter of the cross-flow fan wheel is 0.36 to 0.48. A plane in which the vertical axis of the cross-flow fan is located is a third reference plane, and the third reference plane is parallel to the first reference plane. The distance from the first inlet edge to the rear wall of the first side air duct is a first inlet distance W3, and the distance from the second inlet edge to the fourth inlet edge is a second inlet distance W4. The ratio of the second inlet distance W4 to the first inlet distance W3 is 1.12 to 1.30. The ratio of the first inlet distance W3 to the width W6 of the front air outlet is 0.16 to 0.21. The first inlet distance W3 is the inlet width of the first side air duct 300, and the second inlet distance W4 is the inlet width of the second side air duct 400. As known from the previous embodiments, the first side air duct 300 is easier to intake air, so the inlet of the first side air duct 300 can be slightly smaller than the inlet of the second side air duct 400 to ensure uniform air intake and uniform air outlet of the first side air duct 300 and the second side air duct 400. From the ratio of the first inlet distance to the width of the front air outlet and the ratio of the second inlet distance W4 to the first inlet distance W3, it can be known that the inlet width of the first side air duct 300 and the inlet width of the second side air duct 400 are both much smaller than the width of the front air outlet, that is, the air outlets on both sides of the shell do not affect the air outlet of the front air outlet facing forward, thereby ensuring the rapid adjustment of the temperature on the front side of the air conditioner indoor unit.

[0064] In some embodiments of the present application, the ratio of the perpendicular distance from the first inlet edge to the first reference surface to the perpendicular distance from the second inlet edge to the first reference surface is 0.96 to 0.99.

[0065] In some embodiments of the present application, the ratio of the distance from the third inlet edge 320 to the first reference surface to the distance from the first inlet edge 330 to the first reference surface is 0.79 to 0.83. The ratio of the distance from the fourth inlet edge 420 to the first reference surface to the distance from the second inlet edge 430 to the first reference surface is 0.78 to 0.82.

[0066] In some embodiments of the present application, the front air outlet 140 has a vertical third edge 141 adjacent to the first side wall and a vertical fourth edge 142 adjacent to the second side wall. A first groove with a front opening is arranged at the third edge 141, and the lateral distance L1 between the first groove side wall and the third edge 141 is not less than 6 mm and not greater than 10 mm. When the airflow blown by the cross-flow fan is a refrigeration airflow, the first groove can make the refrigeration airflow passing through the third edge 141 away from the surface of the front wall where the front edge of the first groove is located, thereby avoiding the intersection of the refrigeration airflow and the indoor airflow, and better avoiding the generation of condensation.

[0067] In some embodiments of the present application, a second groove with a front opening is arranged at the fourth edge 142, and the lateral distance L2 between the second groove side wall and the fourth edge 142 is not less than 6 mm and not greater than 10 mm. When the airflow blown by the cross-flow fan is a refrigeration airflow, the second groove can make the refrigeration airflow passing through the fourth edge 142 away from the surface of the front wall where the front edge of the second groove is located, thereby avoiding the intersection of the refrigeration airflow and the indoor airflow, and better avoiding the generation of condensation.

[0068] In some embodiments of the present application, as Figures 1 to 7As shown, the air conditioner indoor unit further comprises a first air deflector 810 and a second air deflector 820. The first air deflector 810 and the second air deflector 820 are rotatably arranged at the front air outlet, and the first air deflector 810 and the second air deflector 820 are arranged in sequence along the width of the front air outlet, and the first air deflector 810 is adjacent to the first side air outlet. The first air deflector 810 has a first rotation position and a second rotation position. In the first rotation position, the first air deflector 810 closes the corresponding air outlet area of the front air outlet. In the second rotation position, one edge of the first air deflector 810 is in contact with the first arc surface. The second air deflector 820 has a third rotation position and a fourth rotation position. In the third rotation position, the second air deflector 820 closes the corresponding air outlet area of the front air outlet. In the fourth rotation position, one edge of the second air deflector 820 is in contact with the second arc surface, and the second air deflector 820 has an acute angle with the forward direction of the second reference surface. When the first air deflector 810 is in the second rotation position and the second air deflector 820 is in the third rotation position, the first air deflector 810 closes the inlet of the first side air duct, and the second air deflector 820 closes the inlet of the second side air duct, and the airflow blown out by the cross-flow fan wheel is entirely blown out from the front air outlet.

[0069] In some embodiments of the present application, as shown in Figures 1 to 7 As shown, the air conditioner indoor unit further comprises an air deflector 900, which is rotatably arranged between the first arc surface and the front edge of the second air duct section, and a plurality of air deflection channels are arranged in the air deflector 900. The plurality of air deflection channels are arranged in sequence along the transverse direction of the air deflector 900. The air deflection channels extend in the front-rear direction. The airflow passing between the first arc section and the front edge of the second air duct section is blown out through the air deflection channels, and when the air deflector 900 rotates, the angle of the airflow blown out through the air deflection channels can be adjusted.

[0070] Of course, in other embodiments of the present application, the air deflection channels can also be air ducts with curvature extending substantially in the front-rear direction. This arrangement can increase the air deflection angle of the air deflector 900.

[0071] In some embodiments of the present application, the air deflector 900 is cooperatively arranged with the first air deflector 810 and the second air deflector 820, so that the air outlet of the air conditioner indoor unit has multiple air outlet modes. As shown in Figure 1 As shown, the outlet of the air deflection channel faces forward, the first air deflector 810 and the second air deflector 820 respectively close the inlets of the corresponding first side air duct and second side air duct, and the airflow is blown forward. As shown in Figure 3 As shown, the air deflector 900 is rotated to the right, the first air deflector 810 and the second air deflector 820 respectively close the inlets of the corresponding first side air duct and second side air duct, and the airflow is blown to the right front. As shown in Figure 4As shown, the air guide block 900 rotates to the left, the first air guide plate 810 and the second air guide plate 820 respectively close the inlets of the corresponding first side air duct and the second side air duct, and the air flow blows to the left front. Figure 5 As shown, the outlet of the air guide channel faces forward, the first air guide plate 810 and the second air guide plate 820 respectively close the air outlet area corresponding to the front air outlet, and the air flow blows from the first side air outlet and the second side air outlet. As shown, Figure 6 As shown, the air guide block 900 rotates to the right, the first air guide plate 810 and the second air guide plate 820 respectively close the air outlet area corresponding to the front air outlet, and more air flow blows from the first side air outlet and less air flow blows from the second side air outlet. As shown, Figure 7 As shown, the air guide block 900 rotates to the left, the first air guide plate 810 and the second air guide plate 820 respectively close the air outlet area corresponding to the front air outlet, and more air flow blows from the second side air outlet and less air flow blows from the first side air outlet.
