[0058] 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 12 The embodiment of the present application provides a three-outlet-air-port air conditioner indoor unit with air deflector plates at front air outlets, which comprises a vertically arranged shell 100, and a blowing passage 200, a first side air duct 300, a second side air duct 400 and at least one air deflector plate assembly arranged in the shell 100. The shell 100 has a front wall 110, a first side wall 120 and a second side wall 130. The front wall 110 is provided with a front air outlet 140 extending in the vertical direction, and the front air outlet 140 is the outlet of the blowing passage 200. The first side wall 120 is connected to one side of the front wall 110, and the first side wall 120 is provided with a first side air outlet 150 extending in the vertical direction, and the front edge of the first side air outlet 150 is on the front wall 110. The first side air outlet 150 is communicated with the blowing passage 200 through the first side air duct 300. The second side wall 130 is connected to the other side of the front wall 110. The second side wall 130 is provided with a second side air outlet 160 extending in the vertical direction, and the front edge of the second side air outlet 160 is on the front wall 110. The second side air outlet 160 is communicated with the blowing passage 200 through the second side air duct 400. At least one air deflector plate assembly is rotatably arranged at the front air outlet. Each air deflector plate assembly comprises a first air deflector plate 901 and a second air deflector plate 902, and the second air deflector plate 902 is on the inner side of the first air deflector plate 901.

[0059] In the air conditioner indoor unit of the embodiment of the present application, the airflow flows out through the blowing 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 rest of the airflow blows out from the second side air outlet 160 through the second side air duct 400. 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 blowing angle. The front air outlet 140, the first side air outlet 150 and the second side air outlet 160 are directed in different directions, which is beneficial to ensure that the interference between the air outlets is small when the three air outlets blow air at the same time, and avoid the lateral air outlet being 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, so as to reduce the air outlet included angle. The air deflector plate assembly arranged at the front air outlet can guide the airflow direction flowing out from the front air outlet, and can also cooperate with the air outlet of the first side air outlet 150 or the second side air outlet 160, so that the air conditioner indoor unit has multiple air outlet modes, which is convenient for meeting the multiple needs of users. The above arrangement avoids the heat exchange air of the air conditioner indoor unit directly blowing on the user, increases the blowing angle and increases the multiple blowing modes, and improves the user experience.

[0060] In some embodiments of the present application, as Figures 1 to 12As shown, the second air deflector is spaced apart and parallel to the corresponding first air deflector.

[0061] In some embodiments of the present application, as shown in Figures 1 to 12 As shown, the air deflector assembly is two, two air deflector assembly along the transverse direction of the front air outlet is arranged in turn, two air deflector assembly along the first reference surface symmetry arrangement. The first reference surface is along the front and back extending vertical plane, and is at the position of the front air outlet along the transverse direction of the middle. Two air deflector assembly is respectively the first air deflector assembly and the second air deflector assembly. The first side air duct of the front wall of the inlet end edge is the first edge 330, the first side air duct of the rear wall of the inlet end edge is the second edge 320, the second side air duct of the front wall of the inlet end edge is the third edge 430, the second side air duct of the rear wall of the inlet end edge is the fourth edge 420. The first air deflector assembly has a first rotating position of closing the corresponding air outlet area of the front air outlet, in the first rotating position, the corresponding first air deflector 901 is in contact with the front surface of the front wall, the corresponding second air deflector 902 is located at the rear side of the first edge 330 and the third edge 430 connection, and is located at the inner side of the first edge 330 and the second edge 320 connection. The second air deflector assembly has a second rotating position of closing the corresponding air outlet area of the front air outlet, in the second rotating position, the corresponding first air deflector 901 is in contact with the front surface of the front wall, the corresponding second air deflector 902 is located at the rear side of the first edge 330 and the third edge 430 connection, and is located at the inner side of the third edge 430 and the fourth edge 420 connection. In the first rotating position, one end of the corresponding first air deflector is in contact with one end of the corresponding first air deflector in the second rotating position, so as to close the front air outlet. The first air deflector assembly further has a third rotating position of opening the corresponding air outlet area of the front air outlet, and the second air deflector assembly further has a fourth rotating position of opening the corresponding air outlet area of the front air outlet. In the third rotating position, the front edge of the corresponding first air deflector 901 is located in the oblique front of the rear edge of the first air deflector 901 close to the first side air duct, and in the fourth rotating position, the front edge of the corresponding first air deflector 901 is located in the oblique front of the first air deflector 901 close to the second side air duct.

[0062] The first air deflector 901 and the second air deflector 902 are arranged in a spaced manner to divide the air flow through the corresponding area into finer air flows, thereby avoiding the direct blowing of strong air flow to the user. The second air deflector 902 is arranged on the rear side of the line connecting the first edge 330 and the third edge 430, and when the first air deflector assembly is in the first rotating position, the corresponding second air deflector 902 is arranged transversely, and the second air deflector 902 can guide the air flow blowing to the second air deflector 902 to blow to the adjacent first side air duct. When the second air deflector assembly is in the second rotating position, the corresponding second air deflector 902 is arranged transversely, and the second air deflector 902 can guide the air flow blowing to the second air deflector 902 to blow to the adjacent second side air duct. Since the corresponding first air deflector 901 is in contact with the front surface of the front wall in the first rotating position and in contact with the front surface of the front wall in the second rotating position, the first air deflector assembly and the second air deflector assembly can only rotate relatively, that is, the edge of the first air deflector assembly in contact with the front wall rotates away from the front wall, and the edge of the second air deflector assembly in contact with the front wall rotates away from the front wall. When the first air deflector assembly is in the third rotating position and the second air deflector assembly is in the fourth rotating position, the rear edges of the two first air deflectors 901 are close to each other, and the two first air deflectors 901 are in a spread shape, guiding the air flow of the front air outlet to blow to the transverse two sides, which can be matched with the corresponding side air outlet, respectively.

[0063] In some embodiments of the present application, as shown in Figures 2 to 3 As shown in the drawings, the air conditioner indoor unit further comprises a cross-flow fan, and the cross-flow fan is arranged in the air supply channel. The ratio of the width L5 of the first air deflector 901 to the diameter of the cross-flow fan is 0.67 to 0.89, and preferably, the ratio of the width L5 of the first air deflector 901 to the diameter of the cross-flow fan is 0.85. The ratio of the width L5 of the first air deflector 901 to the width W6 of the front air outlet is 0.60 to 0.70. Preferably, the ratio of the width L5 of the first air deflector 901 to the width W6 of the front air outlet is 0.66. The ratio of the width L4 of the second air deflector 902 to the width L5 of the first air deflector 901 is 0.45 to 0.63.

[0064] In these embodiments, the size of the first air deflector 901 and the second air deflector 902 is limited. If the size of the second air deflector is similar to that of the first air deflector, the distance between the second air deflector and the first air deflector is relatively wide, the flow line carding effect of the air flow is weak, and vortex is prone to occur between the second air deflector and the first air deflector. In the above limitation, the second air deflector 902 plays a role in carding the flow line of the air flow, and has the effects of multiple air guiding and suppressing vortex between the second air deflector and the first air deflector. As known from the ratio of the first air deflector 901 to the front air outlet, the first air deflector 901 is not arranged in the front air outlet when it is in the transversely extending position.

[0065] In some embodiments of the present application, as shown inFigures 2 to 3 As shown in the figure, the air conditioner indoor unit further comprises a volute and a volute tongue for defining the air supply passage, the cross-flow fan wheel is between the volute and the volute tongue, the first side air duct is close to the volute tongue, and the second side air duct is close to the volute. The second air deflector 902 rotates synchronously with the corresponding first air deflector 901, and the rotation axis 903 is between the second air deflector 902 and the corresponding first air deflector 901. The ratio of the distance a3 between the rotation axis 903 of the first air deflector assembly and the second reference surface 710 to the diameter of the cross-flow fan wheel is 0.54 to 0.60. The second reference surface 710 passes through the vertical axis of the cross-flow fan wheel, and the second reference surface 710 extends along the front-rear direction. The ratio of the minimum distance H3 between the rotation axis 903 and the inner surface of the second air deflector 902 to the minimum distance H4 between the rotation axis 903 and the inner surface of the first air deflector 901 is 0.8 to 1.2, preferably, the ratio of the minimum distance H3 between the rotation axis 903 and the inner surface of the second air deflector 902 to the minimum distance H4 between the rotation axis 903 and the inner surface of the first air deflector 901 is 1. The ratio of the minimum distance H3 between the rotation axis 903 and the inner surface of the corresponding second air deflector 902 to the width L4 of the second air deflector 902 is 0.14 to 0.24. When the first air deflector is transversely arranged, the ratio of the transverse distance a5 between the vertical edge of the first air deflector close to the first reference surface and the corresponding rotation axis to the width L5 of the first air deflector is 0.33 to 0.38. The ratio of the transverse distance between the vertical edge of the corresponding second air deflector close to the first reference surface and the corresponding rotation axis to the width L4 of the second air deflector is 0.35 to 0.40. The ratio of the transverse distance a4 between the vertical edge of the corresponding second air deflector away from the first reference surface and the corresponding rotation axis to the width L5 of the first air deflector is 0.32 to 0.35. In these embodiments, the rotation axis 903 can be deviated towards the first air deflector 901 or the second air deflector 902, preferably, the minimum distances of the rotation axis 903 to the first air deflector 901 and the second air deflector 902 are equal. The rotation axis 903 is on the side of the corresponding first air deflector 901 and the second air deflector 902 close to the first reference surface, and is at a position of about one third of the width direction of the first air deflector 901 and the second air deflector 902.

[0066] In some embodiments of the utility model, as shown in the figure, Figure 3 The ratio of the vertical distance a2 between the vertical edge of the first guide plate close to the air supply passage and the second reference surface to the vertical distance a1 between the vertical edge of the other first guide plate close to the air supply passage and the second reference surface is between 2.76 and 2.96.

[0067] In some embodiments of the utility model, as shown in the figure, Figures 1 to 12As shown, the front edge of the first side air outlet 150 is a first air outlet edge 151. The rear edge of the first side air outlet is a second air outlet edge 152. The second air outlet edge 152 is obliquely forward of the second edge 320, and the first air outlet edge 151 is obliquely forward of the first edge 330. The first edge 330 is obliquely forward of the second edge 320 close to the first side wall 120, and the first air outlet edge 151 is obliquely forward of the second air outlet edge 152 close to the front air outlet. That is, the first side air duct 300 is inclined obliquely forward from back to front, which is more conducive to the air entering from the air supply channel 200.

[0068] In some embodiments of the present application, as shown in Figures 1 to 12 As shown, the rear wall of the first side air duct 300 is a first air duct wall 310, and the front wall of the first side air duct 300 is a second air duct wall 340. Both the first air duct wall 310 and the second air duct wall 340 are inclined surfaces.

[0069] In some embodiments of the present application, as shown in Figures 1 to 12 As shown, the front edge of the second side air outlet is a third air outlet edge 161, and the rear edge of the second side air outlet is a fourth air outlet edge 162. The fourth air outlet edge 162 is obliquely forward of the fourth edge 420, and the third air outlet edge 161 is obliquely forward of the third edge 430. The third edge 430 is obliquely forward of the fourth edge 420 close to the second side wall, and the third air outlet edge 161 is obliquely forward of the fourth air outlet edge 162 close to the front air outlet. That is, the second side air duct 400 is inclined obliquely forward from back to front, which is more conducive to the air entering from the air supply channel 200.

[0070] In some embodiments of the present application, as shown in Figures 1 to 12 As shown, the rear wall of the second side air duct 400 is a third air duct wall 410, and the front wall of the second side air duct 400 is a fourth air duct wall 440. Both the third air duct wall 410 and the fourth air duct wall 440 are inclined surfaces.

[0071] In some embodiments of the present application, as shown in Figure 4As shown, the ratio of the vertical distance W7 from the first edge 330 to the second reference surface to the diameter of the cross-flow fan 700 is 0.86 to 0.95. The lateral distance between the third edge 430 and the first edge 330 is the width W6 of the front air outlet 140, and the ratio of the width W6 of the front air outlet 140 to the diameter of the cross-flow fan 700 is 1.22 to 1.34. This arrangement also ensures that the front air outlet 140 is large enough, and only a small portion of the airflow is from the first side air duct 300 and the second side air duct 500, respectively, and the front air outlet 140 accounts for the majority of the airflow. The vertical distance from the first edge 330 to the first air duct wall is the first distance W3, and the vertical distance from the third edge 430 to the second air duct wall is the second distance W4. The ratio of the first distance W3 to the width W6 of the front air outlet 140 is 0.19 to 0.25. The ratio of the second distance W4 to the first distance W3 is 1 to 1.36. The above arrangement can ensure that the air flow from the first side air duct 300 and the second side air duct 500 is evenly distributed when the front air outlet 140 is closed. Most of the air blown out of the cross-flow fan 700 is deflected towards the volute 500, and the airflow deflected towards the volute tongue 600 is relatively small. The first edge 330 is on the same side as the volute tongue 600, which is conducive to the airflow blown out of the cross-flow fan 700 being concentrated towards the first edge 330. Since the ratio of the second distance W4 to the first distance W3 is greater than 1, the airflow entering the first side air duct 300 and the airflow entering the second side air duct 500 are generally the same.

[0072] In some embodiments of the present application, as shown in Figures 1 to 12 The distance W1 from the second air outlet edge 152 to the first air outlet edge 151 is greater than the first distance W3. This arrangement causes the first side air outlet to be diffuser, which is conducive to increasing the air speed of the first side air outlet, so that the airflow blown out of the first side air outlet blows forward a greater distance, which can take care of users farther away from the air conditioner indoor unit.

[0073] In some embodiments of the present application, as shown in Figures 1 to 10 The distance W2 from the fourth air outlet edge 162 to the third air outlet edge 161 is greater than the second distance W4. This arrangement causes the second side air outlet to be diffuser, which is conducive to increasing the air speed of the second side air outlet, so that the airflow blown out of the air outlet of the second side air duct 500 blows forward a greater distance, which can take care of users farther away from the air conditioner indoor unit.

[0074] In some embodiments of the present application, the distance W1 from the second air outlet edge 152 to the first air outlet edge 151 is equal to the distance W2 from the fourth air outlet edge 162 to the third air outlet edge 161.

[0075] In some embodiments of the present application, as shown in Figures 1 to 12As shown in the figure, the ratio of the transverse distance from the first air outlet edge 151 to the first edge 330 to the width of the front air outlet is 0.18 to 0.22. That is, the part of the shell in front of the first side air duct is small, which can also be called the first wind blocking column, and will not obviously block the airflow, and the main role of the first wind blocking column is to make part of the airflow enter the first side air duct.

[0076] In some embodiments of the utility model, as shown in the figure, Figures 1 to 12 As shown in the figure, the ratio of the transverse distance from the third air outlet edge 161 to the third edge 430 to the width of the front air outlet is 0.18 to 0.22. That is, the part of the shell in front of the second side air duct is small, which can also be called the second wind blocking column, and the second wind blocking column will not obviously block the airflow, and the main role of the second wind blocking column is to make part of the airflow enter the second side air duct.

[0077] In some embodiments of the utility model, as shown in the figure, Figures 1 to 12 As shown in the figure, the volute tongue 600 includes a first air duct section, and the surface of the first air duct section for defining the air supply channel 200 is a first arc surface 610 in a concave shape, and the front end of the first arc surface 610 is connected with 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 the second reference surface 710. The volute casing 500 includes a second air duct section 510, and the surface of the second air duct section 510 for defining the air supply channel 200 is connected with 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, the rear end of the second arc surface 520 is adjacent to the second reference surface 710, and the vertical distance between the rear end of the second arc surface 520 and the second reference surface 710 is greater than the minimum distance between the second arc surface 520 and the second reference surface 710.

[0078] Most of the air blown out from the cross-flow fan 700 will be deviated to the volute casing 500, and the arrangement of the first arc surface 610 and the second air duct section 510 makes part of the airflow close to the volute casing 500 blow to the first arc surface 610 and then blow forward, which is beneficial to the uniformity of the air blown out in the entire air supply channel 200.

[0079] Further, in some embodiments of the utility model, as shown in the figure, Figure 4 As shown in the figure, the ratio of the radius R2 of the first arc surface 610 to 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°.

[0080] In some embodiments of the utility model, as shown in the figure, Figure 4As shown, the radius R1 of the second arc surface 520 is greater than 4 mm and less than 20 mm, the ratio of the radius of the second arc surface 520 to the radius of the first arc surface 610 is 0.20 to 0.25, and the central angle of the second arc surface 520 is 100° to 110°. The above limitations of the second arc surface 520 can make the air flow resistance smaller when the air flow passes through the air supply channel into the second side air duct 500.

[0081] In some embodiments of the present application, as shown in Figure 2 and Figure 3 As shown, the first air duct wall is provided with a first groove 311 extending in the vertical direction, and the first guide plate 801 is rotatably arranged in the first groove 311. The first guide plate 801 is configured to open and close the first side air duct. The thickness b1 of the first guide plate 801 is not less than 2 mm and not greater than 5 mm, the ratio of the width of the first guide plate 801 to the diameter of the cross-flow fan is 0.30 to 0.35, and the ratio of the width of the first guide plate 801 to the width of the front air outlet is 0.24 to 0.28. The depth b2 of the first groove 311 is greater than the thickness b1 of the first guide plate 801, and preferably, the difference between the depth b2 of the first groove 311 and the thickness b1 of the first guide plate 801 is 2 mm. The width L6 of the first groove 311 is greater than the width of the first guide plate 801, and preferably, the difference between the width L6 of the first groove 311 and the width of the first guide plate 801 is 6 mm. The first guide plate 801 is rotatably arranged in the first groove 311 to open and close the first side air duct. When the first guide plate 801 closes the first side air duct, it can prevent condensation and air leakage caused by the heat exchange air flow passing through the first side air duct. The first guide plate 801 can also guide the direction of the air flow passing through the first side air duct. The width of the first groove 311 is greater than the width of the first guide plate 801, and the depth b2 of the first groove 311 is greater than the thickness b1 of the first guide plate 801, which can ensure that the first guide plate 801 can be completely buried in the first groove 311 when the first side air duct is fully opened, thereby reducing the air resistance of the first side air duct.

[0082] In some embodiments of the present application, as shown in Figure 2 and Figure 3As shown, the third air duct wall is provided with a second groove 411 extending in the vertical direction, and the second guide plate 802 is rotatably arranged in the second groove 411, and the second guide plate 802 is configured to open and close the second side air duct. The thickness of the second guide plate 802 is not less than 2 mm and not greater than 5 mm, the ratio of the width L3 of the second guide plate 802 to the diameter of the cross-flow fan is 0.30 to 0.35, and the ratio of the width L3 of the second guide plate 802 to the width W6 of the front air outlet is 0.24 to 0.28. The depth of the second groove 411 is greater than the thickness of the second guide plate 802, and preferably, the difference between the depth of the second groove 411 and the thickness of the second guide plate 802 is 2 mm. The width of the second groove 411 is greater than the width L3 of the second guide plate 802, and preferably, the difference between the depth of the second groove 411 and the thickness of the second guide plate 802 is 6 mm.

[0083] The second guide plate 802 is rotatably arranged in the second groove 411, and the rotation of the second guide plate 802 can open and close the second side air duct, and when the second guide plate 802 is rotated to close the second side air duct, the condensation and air leakage problems caused by the heat exchange airflow passing through the second side air duct can be prevented. The rotation of the second guide plate 802 can also guide the airflow direction passing through the second side air duct. The width of the second groove 411 is greater than the width of the second guide plate 802, and the depth of the second groove 411 is greater than the thickness of the second guide plate 802, which can ensure that the second guide plate 802 can be completely buried in the second groove 411 when the second side air duct is completely opened, thereby reducing the air resistance of the second side air duct.

[0084] In some embodiments of the present application, the first groove and the second groove are symmetrically arranged along the first reference surface, and the first guide plate and the second guide plate are symmetrically arranged along the first reference surface.

[0085] In some embodiments of the present application, as shown in Figure 5 The first guide plate 801 closes the first side air duct, the second guide plate 802 closes the second side air duct, the corresponding first guide vane 901 and the second guide vane 902 of the first guide vane assembly and the second guide vane assembly extend in the front-rear direction, and the front air outlet blows forward, so that long-distance front blowing can be realized. As shown in Figure 6 The first guide plate 801 closes the first side air duct, the second guide plate 802 closes the second side air duct, the first guide vane assembly and the second guide vane assembly are relatively rotated, and the second guide vane assembly rotates at a high speed, so that the first guide vane assembly and the second guide vane assembly are inclined to the right, and right air supply is realized. As shown in Figure 7 The first guide plate 801 closes the first side air duct, the second guide plate 802 closes the second side air duct, the first guide vane assembly and the second guide vane assembly are relatively rotated, and the first guide vane assembly rotates at a high speed, so that the first guide vane assembly and the second guide vane assembly are inclined to the left, and left air supply is realized. As shown in Figure 8As shown, the first guide plate 801 closes the first side air duct, the second guide plate 802 closes the second side air duct, the first air deflector assembly and the second air deflector assembly rotate relative to each other, and the first air deflector assembly rotates to a third position and the second air deflector assembly rotates to a fourth position, the air flow of the front air outlet is guided to blow out to both sides, realizing the small wide-angle air supply. As shown, Figure 9 As shown, the two air deflector assemblies close the front air outlet, the first guide plate 801 completely opens the first side air duct, and the second guide plate 802 completely opens the second side air duct, and the air flow blows out from the first side air outlet and the second side air outlet on both sides, realizing the super wide-angle air supply. As shown, Figure 1 As shown, the two air deflector assemblies close the front air outlet, the first guide plate 801 partially opens the first side air duct to reduce the air volume of the first side air outlet and guide the air flow of the first side air duct to blow out to the oblique front, and the second guide plate 802 completely opens the second side air duct, and most of the air flow blows out from the second side air outlet. As shown, Figure 10 As shown, the two air deflector assemblies close the front air outlet, the first guide plate 801 closes the first side air duct, and the second guide plate 802 completely opens the second side air duct, and the air flow blows out from the second side air outlet.

As shown, Figure 12 As shown, the two air deflector assemblies close the front air outlet, the second guide plate 802 closes the second side air duct, and the first guide plate 801 completely opens the first side air duct, and the air flow blows out from the first side air outlet.

[0086] In some embodiments of the present application, as shown, Figure 4 As shown, a third groove with a front opening is arranged at the first edge, and the transverse distance L1 between the side wall of the third groove and the first edge is not less than 4 mm and not more than 10 mm.

In some embodiments of the present application, as shown, Figure 4 As shown, a fourth groove with a front opening is arranged at the third edge. The transverse distance L2 between the side wall of the fourth groove and the transverse direction of the third edge is not less than 4 mm and not more than 10 mm.
