[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] Please refer to Figure 1 The air duct structure includes an air duct housing 110, a fan 120 and a splitter plate 130. The fan 120 is arranged in the air duct housing 110. The air duct housing 110 is located on the inner side of the air inlet panel of the air conditioner 20, and the air inlet panel has an air inlet 211. The air inlet airflow enters the interior of the indoor unit of the air conditioner 20 through the air inlet 211 on the air inlet panel.

[0026] In some embodiments, the splitter plate 130 is disposed in the air inlet area formed between the air duct housing 110 and the air inlet panel, and the splitter plate 130 extends along the air flow direction of the air inlet area. The air inlet area formed between the air duct housing 110 and the air inlet panel, the air inlet air enters the air inlet area through the air inlet 211, and the air inlet air flows in the vertical direction in the air inlet area (the air inlet air flow direction is shown in FIG. Figure 1 In other words, the diverter plate 130 is vertically disposed in the indoor unit of the air conditioner 20 to reduce the impact on the flow velocity of the incoming air flow.

[0027] In some embodiments, the splitter plate 130 is disposed on one side of the rotation axis of the fan 120, and the first end 131 of the splitter plate 130 is located on the side of the rotation axis of the fan 120 away from the air inlet 211, so that part of the airflow entering from the air inlet 211 bypasses the first end 131 of the splitter plate 130 and then enters the inlet of the fan 120. That is, the first end 131 of the splitter plate 130 is higher than the rotation axis of the fan 120, so as to send part of the incoming airflow to the air inlet position of the fan 120 away from the air inlet 211.

[0028] The present invention provides a splitter plate 130 in the air inlet area formed between the air duct housing 110 and the air inlet panel, and the splitter plate 130 extends along the air flow direction of the air inlet area to guide the air inlet airflow in the air inlet area. The splitter plate 130 is provided on one side of the rotation axis of the fan 120, and the first end 131 of the splitter plate 130 is located on the side of the rotation axis of the fan 120 away from the air inlet 211, so that part of the airflow entering from the air inlet 211 bypasses the first end 131 of the splitter plate 130 and enters the inlet of the fan 120, so that the air inlet airflow in the air inlet area of ​​the fan 120 is evenly distributed, solving the problem of low blade utilization of the air conditioner 20 in the prior art.

[0029] Figure 1 FIG. 2 shows a schematic structural diagram of an embodiment of an air conditioner 20 according to the present invention. Figure 1 The diverter plate 130 is located at the inlet of the fan 120 and is close to the side plate 220 of the air conditioner 20 .

[0030] In some embodiments, the splitter plate 130 is disposed opposite to the side plate 220 of the air conditioner 20, and a splitter gap 140 for air flow to flow in is formed between the splitter plate 130 and the side plate 220 of the air conditioner 20. The air flow entering the indoor unit of the air conditioner 20 from the air inlet 211 is split into strands and enters the air inlet area, one of which flows into the splitter gap 140 and enters the position of the fan 120 away from the air inlet 211 through the separation gap.

[0031] In some embodiments, there are multiple diverter plates 130, and the multiple diverter plates 130 are arranged at intervals along the distribution direction of the two side panels 220 of the air conditioner 20 to divide the air inlet area into multiple different diverter gaps 140. The diverter plates 130 divide the incoming air flow into multiple incoming air flows, and each incoming air flow flows to a different position of the fan 120 through a different incoming air gap 160, so that the blades of the fan 120 are fully utilized, solving the problem of low utilization rate of the blades of the fan 120 in the prior art.

[0032] See also Figure 1 There are two diverter plates 130, and the two diverter plates 130 and the two side plates 220 of the air conditioner 20 are arranged one by one, and a diverter gap 140 for air flow to flow into is formed between each diverter plate 130 and the corresponding side plate 220. That is, the two diverter plates 130 divide the air intake area into two diverter gaps 140 and an intermediate air intake area directly reaching the fan 120, and three different air intake air flows enter the above three different air intake channels respectively to reach different positions of the fan 120, so that the air intake air flow is evenly distributed.

[0033] The splitter plate 130 is arranged parallel to the rotation axis of the fan 120 to improve the utilization rate of the incoming air flow.

[0034] See also Figure 1 The end of the air inlet 211 close to the fan 120 is the air inlet top 212, and the second end 132 of the diverter plate 130 is flush with the air inlet top 212 or is located on the side of the air inlet top 212 away from the fan 120 to improve the utilization rate of the incoming air flow.

[0035] In some embodiments, the first end 131 of the diverter plate 130 is located below the top end of the outer peripheral surface of the fan 120 .

[0036] The diverter plate 130 is fixed relative to the fan 120. In some embodiments, the diverter plate 130 is fixed to the air duct housing 110 or the casing to prevent the diverter plate 130 from shaking and causing damage during the transportation of the air conditioner 20.

[0037] See also Figure 1 The air duct structure further includes an air shield 150. The air shield 150 is disposed between the air inlet panel and the air duct structure, and is located on the side of the first end 131 of the diverter plate 130 away from the rotation axis of the fan 120. An air inlet gap 160 is formed between the air shield 150 and the diverter plate 130 for allowing the airflow on the side of the diverter plate 130 away from the fan 120 to flow toward the inlet of the fan 120. The diverter plate 130 divides the air inlet airflow into a plurality of different air inlet airflows, of which part of the air inlet airflow enters the diverter gap 140, is then blocked by the air shield 150, enters the air inlet gap 160, and thus reaches a position of the fan 120 away from the air inlet 211.

[0038] See also Figure 1 The air conditioner 20 includes a casing and an air duct structure. The air duct structure is arranged in the casing, and the air duct structure is the air duct structure of the above embodiment.
