[0038] Figure 1 This is a schematic structural diagram of an indoor unit of an air conditioner according to an embodiment of the present invention, as shown below. Figure 1 As shown, and with reference Figures 2 to 4 This utility model provides an indoor unit for an air conditioner, including a housing 100. The housing 100 is provided with a first air outlet 101, a second air outlet 102, and a third air outlet 103. Both the first air outlet 101 and the second air outlet 102 extend vertically. The first air outlet 101 is located on one side wall of the housing 100, and the second air outlet 102 is located on the other side wall of the housing 100. The third air outlet 103 is located on the front wall of the housing 100. An air duct is provided inside the housing 100, comprising a main air duct section and a first air duct section 110, a second air duct section 120, and a third air duct section connected to the front end of the main air duct section. The first air duct section 110 is connected to the first air outlet 101, the second air duct section 120 is connected to the second air outlet 102, and the third air duct section is connected to the third air outlet 103.

[0039] The airflow in the main air duct section passes through the first air duct section 110, the second air duct section 120, and the third air duct section, and exits from the first air outlet 101 corresponding to the first air outlet 110, the second air outlet 102 corresponding to the second air outlet 120, and the third air outlet 103 corresponding to the third air outlet 103. The first air outlet 101 is located on one side wall of the housing 100, and the second air outlet 102 is located on the other side wall of the housing 100. The second air duct section 120 can expand the lateral air supply angle of the indoor unit of the air conditioner. The third air outlet 103 is located on the front wall of the housing 100, ensuring that the airflow from the third air outlet 103 can cover the front of the housing 100. The above arrangement can satisfy both left and right air supply and forward air supply volume, meeting the diverse air supply needs of users.

[0040] In some embodiments of this utility model, such as Figure 4 As shown, the indoor unit of the air conditioner also includes a partition 160, disposed within the main air duct section, configured to divide the main air duct section into a first section 134 and a second section. The first section 134 is located above or below the second section. The first section 134 communicates with the first air duct section 110 and the second air duct section 120. The second section 135 communicates with the third air duct section.

[0041] The airflow in the first section 134 passes through the first air duct section 110 and the second air duct section 120, and is blown out from the first air outlet 101 corresponding to the first air duct section 110 and the second air outlet 102 corresponding to the second air duct section 120. The airflow in the second section passes through the third air duct section and is blown out from the third air outlet 103 corresponding to the third air duct section. The partition 160 is provided to prevent the airflow from the first air outlet 101 and the second air outlet 102 from interfering with the airflow from the third air outlet 103, thus avoiding affecting the air delivery effect of the first air outlet 101, the second air outlet 102, and the third air outlet 103.

[0042] In some embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the main air duct section includes a first air duct wall 131 and a second air duct wall 132 disposed opposite to each other. The first air duct section 110 is connected to the first air duct wall 131, and the second air duct section 120 is connected to the second air duct wall 132. The second air duct wall 132 is configured such that the flow direction of the airflow within the main air duct section is towards the side of the housing 100 having the first air outlet 101. The angle of change of the flow direction of the airflow from the main air duct section under the action of the second air duct section 120 is greater than the angle of change under the action of the first air duct section 110.

[0043] The above configuration makes the first air duct have less air resistance than the second air duct, so the air delivery from the first air outlet 101 is relatively smoother. The second air duct wall 132 also makes the airflow direction in the main air duct section face the side of the housing 100 with the first air outlet 101. Therefore, the amount of airflow passing through the first air duct is greater than the amount of airflow passing through the second air duct.

[0044] In some embodiments of this utility model, such as Figure 2 As shown, the indoor unit of the air conditioner also includes a first diversion device, which is located at the front end of the first section 134. The first diversion device is configured to guide and divert the airflow from the main air duct section so that part of the airflow flows to the first air duct section 110 and the rest of the airflow flows to the second air duct section 120.

[0045] The first diversion device can adjust the direction of airflow passing through the first section 134, thereby adjusting the flow rate of airflow entering the first air duct section 110 and the second air duct section 120, and correspondingly adjusting the amount of airflow exiting the first air outlet 101 or the second air outlet 102. For example, without the diversion device, the amount of airflow passing through the first air duct is greater than the amount of airflow passing through the second air duct. By setting the first diversion device, the amount of airflow entering the second air duct can be increased, so that the final amount of airflow passing through the first air duct and the amount of airflow passing through the second air duct are equal or nearly equal, so that the amount of airflow blown out of the first air outlet 101 and the second air outlet 102 is equal or nearly equal.

[0046] In some embodiments of this utility model, such as Figure 2 As shown, the first air distribution device includes a first air distribution plate 910, a second air distribution plate 920, and a third air distribution plate 930. The first air distribution plate 910 is curved. A portion of the first air distribution plate 910 is located within the main air duct section, and another portion is located within the second air duct section. The surface of the first air distribution plate 910 facing the second air duct wall 132 is a concave surface. The second air distribution plate 920 is curved. The second air distribution plate 920 is located on the side of the first air distribution plate away from the second air duct wall 132, and the surface of the second air distribution plate 920 facing the first air distribution plate 910 is a concave surface. The curvature of the first air distribution plate 910 is greater than that of the second air distribution plate 920. The second air distribution plate 920 is located within the main air duct section, and the air outlet edge of the second air distribution plate 920 is near the junction of the front air duct wall of the first air duct section 110 and the front air duct wall of the second air duct section 120. The third air distribution plate 930 is disposed on the side of the second air distribution plate 920 that is away from the first air distribution plate 910. The third air distribution plate 930 is curved, and the surface of the third air distribution plate 930 facing the second air distribution plate 920 is a concave surface. The included angle between the cross-section at the air outlet edge of the third air distribution plate 930 and the cross-section at the air inlet edge of the third air distribution plate 930 is greater than or equal to 160°.

[0047] The first air distribution plate 910 guides a portion of the airflow from the first section 134 into the second air duct section 120. By setting the first air distribution plate 910, the resistance to airflow entering the second air duct section 120 from the main air duct section is also reduced. The second air distribution plate 920 divides the airflow from the main air duct section into two approximately equal parts. One part of the airflow, guided by the first air distribution plate 910 on its surface facing the second air distribution plate 920, enters the second air duct section 120. The other part of the airflow, guided by the third air distribution plate 930 on its surface facing the third air distribution plate 930, enters the first air duct section 110. The third air distribution plate 930 facilitates the guidance of airflow into the first air duct.

[0048] In some other embodiments of this utility model, the third air distribution plate 930 is flat.

[0049] In some embodiments of this utility model, such as Figure 3 As shown, the indoor unit of the air conditioner also includes a second diversion device, which is located at the front end of the second section 135. The second diversion device is configured to guide and divert the airflow from the main air duct section so that part of the airflow flows to one side of the third air outlet 103 and part of the airflow flows to the other side of the third air outlet 103.

[0050] Because the airflow blowing towards the first air duct wall 131 and the second air duct wall 132 in the second section is uneven, a second flow-dividing device is needed to even out the airflow. The second flow-dividing device can adjust the direction of the airflow passing through the second section, thereby adjusting the flow rate of the airflow on one and the other side of the third air outlet 103, and correspondingly adjusting the amount of airflow flowing out of the third air outlet 103 on both sides of the lateral direction. For example, by setting up the second flow-dividing device, the flow rate of the airflow on one and the other side of the lateral direction of the third air outlet 103 can be adjusted so that the final amount of airflow flowing out of the third air outlet 103 on both sides of the lateral direction is equal or nearly equal.

[0051] In some embodiments of this utility model, the second diversion device is disposed within the third air duct section.

[0052] In some embodiments of this utility model, such as Figure 1 and Figure 3 As shown, the indoor unit of the air conditioner also includes a baffle block 150. The rear surface of the baffle block 150 is arched rearward. The baffle block 150 is disposed at the third air outlet 103 and configured such that airflow flows out from the gap between the baffle block 150 and the edge of the third air outlet 103.

[0053] The rearward arched rear surface of the wind deflector 150 facilitates the diversion of gas within the third air duct section, guiding the airflow out through the gap defined between the wind deflector 150 and the edge of the third air outlet 103.

[0054] Furthermore, in some embodiments of this utility model, the wind deflector 150 is movably disposed at the third air outlet 103 in the front-back direction.

[0055] The wind deflector 150 moves in the front-to-back direction, which changes the size of the gap between the wind deflector 150 and the edge defined by the third air outlet 103, thereby changing the amount of airflow flowing out of the third air outlet 103. When the wind deflector 150 moves forward, the gap increases, and the amount of airflow flowing out of the third air outlet 103 increases. When the wind deflector 150 moves backward, the gap decreases, and the amount of airflow flowing out of the third air outlet 103 decreases.

[0056] In some embodiments of this utility model, such as Figure 3 As shown, the second air diversion device includes a fourth air diversion plate 940 and a fifth air diversion plate 950. The fourth air diversion plate 940 is curved. The surface of the fourth air diversion plate 940 facing the housing 100 and having the second air outlet 102 is a concave surface. The fourth air diversion plate 940 is disposed adjacent to the second air duct wall 132. The fifth air diversion plate 950 is curved. The fifth air diversion plate 950 is located on the side of the fourth air diversion plate away from the second air duct wall 132, and the surface of the fifth air diversion plate 950 facing the fourth air diversion plate 940 is a concave surface. The curvature of the fourth air diversion plate 940 is greater than that of the fifth air diversion plate 950. The air outlet edge of the fifth air diversion plate 950 is adjacent to the center of the rear surface of the wind deflector block 150.

[0057] The fourth air distributor 940 guides a portion of the airflow from the second section 135 towards the third outlet 103 near the second duct wall 132. By installing the fourth air distributor 940, the resistance to the airflow from the second section towards the third outlet 103 near the second duct wall 132 is also reduced. The surface of the fifth air distributor 950 facing the fourth air distributor 940 also guides a portion of the airflow from the second section 135 towards the third outlet 103 near the second duct wall 132. The fourth air distributor 940 has a greater ability to change the airflow direction than the fifth air distributor 950. The fifth air distributor 950 also has a diversion function, dividing the airflow from the second section into two roughly equal parts. One part is blown out from the gap on the side of the third outlet 103 near the second duct wall 132, and the other part is blown out from the gap on the other side of the third outlet 103 near the second duct wall 132, ensuring a balanced airflow from both sides of the third outlet 103.

[0058] In some embodiments of this utility model, such as Figure 3As shown, the second air diversion device also includes a sixth air diversion plate 960, which is disposed on the side of the fifth air diversion plate 950 opposite to the fourth air diversion plate 940. The sixth air diversion plate 960 is flat and is configured to direct airflow toward the side of the third air outlet 103 adjacent to the first air outlet 101. The sixth air diversion plate 960 also facilitates guiding airflow toward the other side of the third air outlet 103 adjacent to the second air duct wall 132.

[0059] In some embodiments of this utility model, such as Figure 1 As shown, the first air outlet 101 and the second air outlet 102 are respectively located at the front ends of the two side walls of the housing 100. This arrangement allows the first air outlet 101 and the second air outlet 102 to be as close as possible to the user's activity space that needs to be heated or cooled, so that the airflow blown out by the first air outlet 101 and the second air outlet 102 can directly reach the user's activity space.

[0060] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
