[0025] 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.

[0026] See also Figure 1 and Figure 2 The flow dividing device 10 of the present invention is used to be arranged in the air duct of the air conditioner 20. The flow dividing device 10 includes a flow dividing plate 110 and a driving assembly, and the flow dividing plate 110 extends along the air flow direction of the air duct. The driving assembly is drivingly connected to the flow dividing plate 110 to drive the flow dividing plate 110 to move along the air flow direction. When the first end 111 of the flow dividing plate 110 is located on the side where the axis of the centrifugal fan blade 210 of the air conditioner 20 is away from the air inlet 220 of the air conditioner 20, the airflow located on the side of the flow dividing plate 110 away from the inlet of the centrifugal fan blade 210 bypasses the flow dividing plate 110 and enters the inlet of the centrifugal fan blade 210.

[0027] The present invention sets a diverter device 10 in the air duct of the air conditioner 20, and makes the diverter plate 110 of the diverter device 10 movably set along the air flow direction of the air duct. In this way, by adjusting the position of the diverter plate, the first end 111 of the diverter plate 110 can be located on the side of the axis of the centrifugal fan blade 210 of the air conditioner 20 away from the air inlet 220 of the air conditioner 20, so that the airflow located on the inlet side of the diverter plate 110 away from the centrifugal fan blade 210 bypasses the diverter plate 110 and enters the inlet of the centrifugal fan blade 210, so that the airflow in the air duct of the air conditioner 20 is evenly delivered to the inlet area of ​​the centrifugal fan blade 210, thereby solving the problem of low blade utilization rate of the air conditioner 20 in the prior art.

[0028] Figure 1 FIG. 2 shows a schematic structural diagram of an embodiment of an air conditioner according to the present invention. Figure 1 At least a portion of the diverter plate 110 is located between the air inlet 220 of the air duct and one end of the centrifugal fan blade 210 of the air conditioner 20 away from the air inlet 220 , so that the air flow entering from the air inlet 220 of the air conditioner 20 is divided into branches and enters the air inlet area of ​​the centrifugal fan blade 210 .

[0029] In some embodiments, there are multiple splitter plates 110 , and the multiple splitter plates 110 are arranged at intervals along a direction perpendicular to the flow direction of the airflow.

[0030] In some embodiments, a plurality of splitter plates 110 are arranged in parallel to increase the air intake velocity of the air flow.

[0031] See also Figure 1 There are two diverter plates 110, and the two diverter plates 110 are respectively arranged on opposite sides of the axis of the centrifugal fan blade 210. In some embodiments, the two diverter plates 110 are symmetrically arranged relative to the axis of the centrifugal fan blade 210.

[0032] A flow dividing channel 130 is formed between each flow dividing plate 110 and a corresponding side wall of the air duct.

[0033] See also Figure 1 The air duct is arranged on the upper side of the air inlet 220, and the second end 112 of the splitter plate 110 is located below the top of the air inlet 220 or flush with the top of the air inlet 220 to improve the utilization rate of the incoming air flow.

[0034] Figure 2 Shows Figure 1 Schematic diagram of the structure of the flow divider in the air conditioner. Figure 2 The driving assembly includes a motor 121 and a transmission gear 122 mounted on an output shaft 123 of the motor 121. A rack portion 113 is provided on the diverter plate 110. The transmission gear 122 meshes with the rack portion 113. The rack portion 113 is arranged along the flow direction of the airflow. This arrangement can make the diverter device in this embodiment simple in structure and easy to implement.

[0035] In some embodiments, the splitter plate 110 is meshed with the transmission gear 122 of the driving assembly through the meshing of the upper rack portion 113 of the splitter plate 110 to realize the movement of the splitter plate 110 in the air duct of the air conditioner 20 along the air flow direction of the air inlet 220. Under different speed conditions, different distribution states of the air inlet area of ​​the centrifugal fan blades 210 are realized by the splitter plate 110 at different positions in the air duct of the air conditioner 20, so as to realize a uniform distribution state of the intake air flow in the air inlet area of ​​the centrifugal fan blades 210.

[0036] In some embodiments, the driving assembly includes a piston cylinder, and a piston rod of the piston cylinder is connected to the diverter plate 110 to drive the diverter plate 110 to move. This arrangement can make the driving method of the baffle device in this embodiment simple in structure and easy to implement.

[0037] In the first embodiment, the driving assembly includes a motor 121 and a transmission gear 122. The motor 121 drives the transmission gear 122 to rotate, thereby driving the rack portion 113 meshing with the transmission gear 122 to move, so as to drive the splitter plate 110 to move along the airflow direction.

[0038] In the second embodiment, the driving assembly includes a piston cylinder, and the movement of the piston cylinder drives the splitter plate 110 connected to the piston rod to move, so as to drive the splitter plate 110 to move along the flow direction of the airflow.

[0039] See also Figure 1 The flow dividing device 10 further includes a baffle 140. The baffle 140 is used to be arranged on a side of the centrifugal fan blade 210 away from the air inlet 220. The baffle 140 is arranged opposite to and spaced from the first end 111 of the flow dividing plate 110, so that the airflow on the side of the flow dividing plate 110 away from the inlet of the centrifugal fan blade 210 can flow to the inlet of the centrifugal fan blade 210 through the gap between the baffle 140 and the flow dividing plate 110 under the shielding effect of the baffle 140, thereby improving the utilization rate of the inlet airflow.

[0040] See also Figure 1 The air conditioner 20 includes a housing, a centrifugal fan blade 210 disposed in the housing, and the diverter device 10 of the above embodiment, wherein the diverter plate 110 of the diverter device 10 is disposed on one side of the inlet of the centrifugal fan blade 210. In some embodiments, the air intake mode of the air conditioner 20 is bottom intake and top outlet.

[0041] See also Figure 1 The diversion device 10 divides the incoming air flow sent into the air inlet 220 in the air duct into three incoming air flows, two of which enter the air inlet area of ​​the centrifugal fan blade 210 from a direction away from the air inlet 220 of the air conditioner 20 on the air inlet area of ​​the centrifugal fan blade 210, and one incoming air flow enters the air inlet area of ​​the centrifugal fan blade 210 directly from a direction close to the air inlet 220 of the air conditioner 20 on the air inlet area of ​​the centrifugal fan blade 210, thereby improving the utilization rate of the centrifugal fan blade 210.

[0042] In the first embodiment, when the centrifugal fan blades 210 of the air conditioner 20 are at a relatively low speed, the transmission gear 122 of the driving assembly meshes with the rack portion 113 to drive the splitter plate 110 to move in a direction close to the air inlet 220 of the air conditioner 20. At this time, the unevenness of the air intake in the air intake area of ​​the centrifugal fan blades 210 in the air duct of the air conditioner 20 is relatively serious, so the splitter plate 110 sends more air intake airflow into the air intake area of ​​the centrifugal fan blades 210, thereby improving the utilization rate of the centrifugal fan blades 210 away from the air inlet 220 of the air conditioner 20, achieving uniform distribution of the air intake airflow entering the air inlet 220 of the air conditioner 20 in the air intake area of ​​the centrifugal fan, and reducing the uneven distribution of the load of the motor 121.

[0043] In the second embodiment, when the centrifugal fan blades 210 of the air conditioner 20 are at a relatively high speed, the transmission gear 122 of the driving assembly meshes with the rack portion 113 to drive the splitter plate 110 to move in the direction of the air inlet 220 of the air conditioner 20. At this time, the unevenness of the air inlet area of ​​the centrifugal fan blades 210 in the air duct of the air conditioner 20 is relatively light, so the splitter plate 110 sends less air inlet air into the air inlet area of ​​the centrifugal fan blades 210, achieving uniform distribution of the air inlet air entering the air inlet 220 of the air conditioner 20 in the air inlet area of ​​the centrifugal fan.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0045] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0046] A flow divider 10 is provided in the air duct of the air conditioner 20, and the flow divider 10 is used to send the air flow distribution area in the air duct of the air conditioner 20 into the area of ​​the centrifugal fan blades 210. The flow divider 10 includes a flow divider plate 110 and a driving assembly, and the driving assembly is used to drive the flow divider plate 110 to move along the air flow direction. When the first end 111 of the flow divider plate 110 is located at a side of the axis of the centrifugal fan blades 210 of the air conditioner 20 away from the air inlet 220 of the air conditioner 20, the air flow located at the side of the flow divider plate 110 away from the inlet of the centrifugal fan blades 210 bypasses the flow divider plate 110 and enters the inlet of the centrifugal fan blades 210, thereby solving the problem of low blade utilization of the air conditioner 20 in the prior art.
