[0061] Figure 1 is a schematic structural diagram of an air conditioner indoor unit according to one embodiment of the present application, as shown in Figure 1 , and referring to Figures 2 to 7The utility model embodiment provides a kind of front air outlet and two sides air outlet's air conditioner indoor unit, including vertically arranged shell 100, and the air supply passage 200, first side air duct 300 and second side air duct 400 being arranged in shell 100.The shell 100 has front wall 110, first side wall 120 and second side wall 130.Front wall 110 is opened on and extends in vertical direction front air outlet 140, and front air outlet 140 is the export of air supply passage 200.The area of front wall 110 on the two sides of front air outlet 140 is the closed area of not transparent air.The first side wall 120 is connected to one side of front wall 110, and first side wall 120 is provided with first side air outlet 150, and the front edge of first side air outlet 150 is at the junction of front wall 110 and first side wall 120.First side air outlet 150 is communicated with air supply passage 200 by first side air duct 300.The second side wall 130 is connected to the other side of front wall 110.The second side wall 130 is provided with second side air outlet 160, and the front edge of second side air outlet 160 is at the junction of front wall 110 and second side wall 130.Second side air outlet 160 is communicated with air supply passage 200 by second side air duct 400.

[0062] In the air conditioner indoor unit of the utility model embodiment, air flow flows out through air supply passage 200, part of air flow flows out from front air outlet 140, part of air flow flows out from first side air outlet 150 through first side air duct 300, and the rest of air flow blows out from second side air outlet 160 through second side air duct 400.The first side air outlet 150 and the second side air outlet 160 on the two sides of the shell 100 can effectively increase the horizontal air supply angle, realize wide-area air supply with air supply included angle above 165 °, and further, since the first side air outlet 150 and the second side air outlet 160 are both adjacent to the front wall, not only is it convenient to realize compact air duct layout inside the air conditioner indoor unit, significantly reducing the thickness of the air conditioner indoor unit with multiple air outlets in the front-rear direction, but also it is convenient to set the air duct for the first side air outlet 150 and the second side air outlet 160, which can blow out a certain forward component air flow, so that the air flow blown out from the first side air outlet 150 and the second side air outlet 160 has a certain forward movement speed component, and the air flow blown out from the first side air outlet 150 and the second side air outlet 160 moves in the lateral front direction, which is better for blowing from the surrounding side to the surrounding area of the user, without directly blowing to the user.The front air outlet 140, the first side air outlet 150 and the second side air outlet 160 are oriented differently, which is also conducive to ensuring that the interference between the air outlets is small when the three air outlets blow air at the same time, avoiding the lateral air outlet being biased to the central air outlet under the suction effect of the air outlet of the front air outlet 140 of the front wall, resulting in a decrease in the air outlet included angle.The above setting can solve the problems that the air conditioner indoor unit with single air outlet is easy to cause direct blowing of heat exchange air to the user, the air supply angle is limited in a narrow area, and the air supply mode is limited, and can avoid poor user experience, and even affect the health of the user.

[0063] In some embodiments of the present application, as shown in Figure 1 and Figure 2 shown, the indoor unit of the air conditioner further comprises a volute 500, a volute tongue 600 and a cross-flow fan 700 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 cross-flow fan 700 is arranged in the air supply passage 200. The volute tongue 600 comprises a first air duct section, and the surface of the first air duct section for defining the air supply passage 200 is a first arc surface 610 in a concave shape. The front end of the first arc surface 610 is connected to the rear wall of the first side air duct 300. The front end of the first arc surface 610 is obliquely in front of the 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 and back, 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 the surface of the second air duct section 510 for defining the air supply passage 200 is connected to the rear wall of the second side air duct 400 through a second arc surface 520. The front end of the second arc surface 520 is obliquely in front of the 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 the vertical distance between the rear end of the second arc surface 520 and the first reference surface is greater than the minimum distance between the second arc surface 520 and the first reference surface.

[0064] Most of the air blown out of the cross-flow fan 700 will be deflected to one side of the volute 500. The arrangement of the first arc surface 610 and the second air duct section 510 causes a portion of the airflow close to the volute 500 to be blown towards the first arc surface 610 and then blown forward, which is beneficial to the uniformity of the air outflow in the entire air supply passage 200.

[0065] 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°.

[0066] 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 section is 0.2 to 0.25, and the central angle of the second arc surface is 100° to 110°. The above limitations on the second arc surface can make the flow resistance of the airflow passing through the air supply passage 200 into the second side air duct 400 smaller.

[0067] In some embodiments of the present application, as shown in Figures 1 to 5As shown, the front air outlet 140 has a vertical first edge 141 adjacent to the first side wall 120 and a vertical second edge 142 adjacent to the second side wall 130. The front edge of the first side air outlet 150 is a first connecting edge 151, and the front edge of the second side air outlet 160 is a second connecting edge 161. The transverse distance between the first edge 141 and the second edge 142 is the width of the front air outlet. The ratio of the distance between the first edge 141 and the first connecting edge 151 to the width of the front air outlet is 0.2 to 0.33. The ratio of the distance between the second edge 142 and the second connecting edge 161 to the width of the front air outlet is 0.2 to 0.33. This arrangement ensures that the width of the front air outlet on the front wall is large enough to ensure that the air conditioner indoor unit has sufficient air volume for forward air outlet, which is beneficial to forward air outlet. The distance between the first edge 141 and the first connecting edge 151 is 0.9 to 1.1 times the distance between the second edge 142 and the second connecting edge 161. That is, on the front wall 110, the front air outlet 140 is located near the center line of the front wall 110 and slightly offset to one side in the transverse direction. Of course, the front air outlet 140 can also be located on the center line of the front wall 110.

[0068] In some embodiments of the present application, as shown in Figures 1 to 5 As shown, the upper edges of the front air outlet 140, the first side air outlet 150, and the second side air outlet 160 are flush. The lower edges of the front air outlet 140, the first side air outlet 150, and the second side air outlet 160 are flush. The ratio of the width W2 of the front air outlet 140 to the diameter of the cross-flow fan 700 is 1.29 to 1.42, which ensures the air volume of the front air outlet 140. The ratio of the width of the first side air outlet 150 to the width of the front air outlet 140 is 0.25 to 0.33, and the ratio of the width of the second side air outlet 160 to the width of the front air outlet 140 is 0.25 to 0.33. That is, the air outlet area of the first side air outlet 150 and the second side air outlet 160 is significantly smaller than that of the front air outlet 140, and the air outlet area of the first side air outlet 150 and the second side air outlet 160 is similar. This arrangement ensures that the front air outlet 140, the first side air outlet 150, and the second side air outlet 160 simultaneously air outlet, or when the first side air outlet 150 or the second side air outlet 160 air outlets alone, the air flow can be more appropriately blown to the area where the user usually stays and its surroundings, which can effectively reduce or even completely avoid the situation that the air flow blown by the air conditioner indoor unit directly hits the user.

[0069] In some embodiments of the present application, as shown in Figure 2 As shown, 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.

[0070] In some embodiments of the present application, as shown inFigures 1 to 5 As shown in the drawings, the rear edge of the first side air outlet 150 is in the oblique front of the inlet end edge of the rear wall of the first side air duct 300. The first connecting edge 151 is in the oblique front of the inlet end edge of the front wall of the first side air duct 300. The inlet end edge of the front wall of the first side air duct 300 is in the oblique front of the inlet end edge of the rear wall of the first side air duct 300 close to the first side wall 120. That is, the first side air duct 300 is inclined to the oblique front from back to front, which is more conducive to the entry of the air outlet through the air supply channel 200.

[0071] In some embodiments of the utility model, the ratio of the distance from the inlet end edge of the rear wall of the first side air duct 300 to the first reference surface to the distance from the inlet end edge of the front wall of the first side air duct 300 to the first reference surface is 0.7 to 0.75.

[0072] In some embodiments of the utility model, as shown in the drawings, Figures 1 to 5 As shown in the drawings, the rear edge of the second side air outlet 160 is in the oblique front of the inlet end edge of the rear wall of the second side air duct 400. The second connecting edge 161 is in the oblique front of the inlet end edge of the front wall of the second side air duct 400. The inlet end edge of the front wall of the second side air duct 400 is in front of the inlet end edge of the rear wall of the second side air duct 400. That is, the second side air duct 400 is inclined to the oblique front from back to front, which is more conducive to the entry of the air outlet through the air supply channel 200.

[0073] In some embodiments of the utility model, the ratio of the vertical distance from the inlet end edge of the rear wall of the second side air duct 400 to the first reference surface to the vertical distance from the inlet end edge of the front wall of the second side air duct 400 to the first reference surface is 0.98 to 1.02.

[0074] In some embodiments of the utility model, as shown in the drawings, Figures 1 to 5 As shown in the drawings, the inlet end of the front wall of the first side air duct 300 is the first inlet edge 330, and the inlet end of the front wall of the second side air duct 400 is the second inlet edge 430. The ratio of the vertical distance W4 from the first inlet edge 330 to the first reference surface to the vertical distance W3 from the second inlet edge 430 to the first reference surface is 1.27 to 1.35. That is, the vertical distance W4 from the first inlet edge 330 to the first reference surface is greater than the vertical distance W3 from the second inlet edge 430 to the first reference surface. Since the air outlet from the cross-flow fan is more concentrated on one side of the volute 500, this arrangement can make the amount of air outlet entering the first side air duct 300 and the second side air duct 400 of the air supply channel 200 not much different, thereby ensuring that the air outlet amount of the first side air outlet 150 and the second side air outlet 160 is not much different, and ensuring that the air outlet of the shell 100 on both sides is uniform.

[0075] In some embodiments of the utility model, as shown in the drawings, Figure 2As shown, the rear wall of the first side air duct 300 is a first air duct wall 310, the front wall of the first side air duct 300 is a second air duct wall 340, and the first air duct wall 310 and the second air duct wall 340 are both inclined surfaces.

The second reference surface is a vertical plane perpendicular to the first reference surface. 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 is beneficial 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 blows forward for a longer distance, and users farther away from the air conditioner indoor unit can be taken care of.

[0076] In some embodiments of the present application, preferably, the first included angle b is less than 40°.

[0077] In some embodiments of the present application, as shown, Figure 2 As shown, the rear wall of the second side air duct 400 is a third air duct wall 410, the front wall of the second side air duct 400 is a fourth air duct wall 440, and the third air duct wall 410 and the fourth air duct wall 440 are both inclined surfaces.

That is, along the flow direction of the airflow, the second side air duct 400 gradually widens, so that the second side air duct 400 is a diffuser section, which improves the static pressure of the airflow and is beneficial to improve the wind speed of the second side air duct 400, so that the airflow blown out of the second side air outlet 160 blows forward for a longer distance, and users farther away from the air conditioner indoor unit can be taken care of.

The ratio of the first inlet distance W6 to the second inlet distance W7 is 0.91 to 0.98. As known from the previous embodiments, the first side air duct 300 is easier to inhale, 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 that the air inlets of the first side air duct 300 and the second side air duct 400 are uniform.

The ratio of the vertical distance from the second center line to the third reference plane to the distance from the first edge 141 to the third reference plane is 0.8 to 0.85.
