When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0031] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" refer to the upper and lower positions of the air duct splitter when it is installed in the indoor unit of the air conditioner under normal operating conditions. Figure 1 and Figure 2 The drawing orientation, "inner" and "outer" refer to the inner and outer sides relative to the contour of the corresponding component itself. The terms "first," "second," etc., used in this disclosure are for distinguishing one element from another and do not have sequential or importance.

[0032] According to a first aspect of the specific embodiments of this disclosure, an air duct diversion device is provided, which is installed in the housing 3 of an air conditioning indoor unit, with reference to... Figures 3 to 5 As shown, the housing 3 has a first air outlet 31 and a second air outlet 32. Inside the housing 3 is a main air duct 4 and a fan 6 that blows air into the main air duct 4. The main air duct 4 is fluidly connected to the first air outlet 31 via a first branch air duct 51, and to the second air outlet 32 ​​via a second branch air duct 52. (Reference) Figures 1 to 5As shown, the air duct diversion device may include a mounting part 1 and a diversion part 2. The mounting part 1 may be fixedly connected to the housing 3. The diversion part 2 may extend into the main air duct 4 connected to the fan 6 to divide the airflow in the main air duct 4. The diversion part 2 may include a plurality of first guide channels 21 and a plurality of second guide channels 22. The plurality of first guide channels 21 and the plurality of second guide channels 22 may be arranged alternately in the vertical direction. The first guide channels 21 can guide the airflow in the main air duct 4 to the first diversion channel 51 connected to the main air duct 4, and the second guide channels 22 can guide the airflow in the main air duct 4 to the second diversion channel 52 connected to the main air duct 4. In a specific embodiment of this disclosure, the top of the diversion part 2 may be attached to the top wall of the main air duct 4, the bottom of the diversion part 2 may be attached to the bottom wall of the main air duct 4, and the two sides of the diversion part 2 may be attached to the side walls of the main air duct 4. In another specific embodiment of this disclosure, the top of the diversion section 2 may also form a gap with the top wall of the main air duct 4, and / or the bottom of the diversion section 2 may also form a gap with the bottom wall of the main air duct 4. It should be noted that, in the specific embodiments of this disclosure, the staggered arrangement of multiple first guide channels 21 and multiple second guide channels 22 in the vertical direction can include various arrangement methods. As one option, the multiple first guide channels 21 and multiple second guide channels 22 can be arranged alternately in the vertical direction, for example, in the manner of "first guide channel 21-second guide channel 22-first guide channel 21-second guide channel 22". As another option, the multiple second guide channels 22 can also be divided into multiple groups (each group consists of one or two) and inserted between the multiple first guide channels 21 at intervals, for example, in the manner of "first guide channel 21-first guide channel 21-second guide channel 22-first guide channel 21-second guide channel 22-second guide channel 22-first guide channel 21".

[0033] Through the above technical solution, the air duct diversion device provided in this disclosure can divide the airflow in the main air duct 4 into multiple first branch airflows and multiple second branch airflows arranged alternately in the vertical direction by multiple first guide channels 21 and multiple second guide channels 22 arranged alternately in the vertical direction. That is to say, the airflow in the main air duct can be roughly evenly divided, the multiple first branch airflows can be arranged in the vertical direction and can flow out from the first air outlet 31 on the housing 3 through the first air diversion channel 51, so that the first air outlet 31 discharges air evenly from top to bottom, and the multiple second branch airflows can be arranged in the vertical direction and can flow out from the second air outlet 32 ​​on the housing through the second air diversion channel 52, so that the second air outlet 32 ​​discharges air evenly from top to bottom, and the airflow volume of the first air outlet 31 and the airflow volume of the second air outlet 32 ​​are approximately the same.

[0034] In a specific embodiment of this disclosure, the first guide channel 21 and the second guide channel 22 may have the same height in the vertical direction, and the number of the first guide channel 21 and the second guide channel 22 may also be the same or similar, so that the airflow in the main air duct can be roughly evenly distributed to the first branch air duct 51 and the second branch air duct 52.

[0035] refer to Figure 1 and Figure 2 As shown, the first guide channel 21 may include a first airflow inlet 211, a first airflow outlet 212, and a first guide cavity 210. The first airflow inlet 211 and the first airflow outlet 212 can be fluidly connected through the first guide cavity 210. The first airflow inlet 211 can be located on the side of the first guide channel 21 facing the fan 6, so that the airflow blown out by the fan 6 enters the first airflow inlet 211 to form a first branch airflow. The first branch airflow can flow through the first guide cavity 210 to the first airflow outlet 212. (Refer to...) Figure 4 and Figure 5 As shown, the first airflow outlet 212 can be located on the side of the first guide channel 21 facing the first branch airflow 51, so as to introduce the first branch airflow into the first branch airflow 51.

[0036] refer to Figure 1 and Figure 2 As shown, the second guide channel 22 may include a second airflow inlet 221, a second airflow outlet 222, and a second guide cavity 220. The second airflow inlet 221 and the second airflow outlet 222 can be fluidly connected through the second guide cavity 220. The second airflow inlet 221 can be located on the side of the second guide channel 22 facing the fan 6, so that the airflow blown out by the fan 6 enters the second airflow inlet 221 to form a second branch airflow. The second branch airflow can flow through the second guide cavity 220 to the second airflow outlet 222. (Refer to...) Figure 4 and Figure 5 As shown, the second airflow outlet 222 can be located on the side of the second guide channel 22 facing the second branch airflow 52, ​​so as to introduce the second branch airflow into the second branch airflow 52.

[0037] In the specific embodiments of this disclosure, reference is made to Figures 3 to 5 As shown, the second air distribution duct 52 is positioned in the air outlet direction of the fan 6, and its extension direction is roughly the same as that of the fan 6. The extension direction of the first air distribution duct 51 is at a certain angle to the air outlet direction of the fan 6. This causes the airflow in the main air duct 4 to tend to flow towards the second air distribution duct 52. The area of ​​the first air outlet 212 can be larger than the area of ​​the second air outlet 222 to further improve the uniformity of airflow distribution in the main air duct 4 by the first guide channel 21 and the second guide channel 22.

[0038] refer to Figure 1 and Figure 2 As shown, two adjacent guide channels can be separated by a partition 23 to prevent direct fluid communication between the two adjacent guide channels.

[0039] In order to form the first guide cavity 210, refer to Figure 2 , Figure 4 and Figure 5 As shown, the first guide channel 21 may also include a first guide wall 213 that blocks the flow between the main air duct 4 and the second branch air duct 52 to prevent the first branch airflow from flowing into the second branch air duct 52. When there are guide channels above and below the first guide channel 21, the first guide wall 213 can be connected to two adjacent partitions 23 to form a first guide cavity 210, so that the first guide cavity 210 has only two openings: a first airflow inlet 211 and a first airflow outlet 212, to ensure that all the first branch airflow is introduced into the first branch air duct 51. When the first guide channel 21 is located at the top or bottom of multiple guide channels, the first guide wall 213 can be connected to the top or bottom wall of the main air duct 4 and the adjacent partitions 23 to form a first guide cavity 210, so that the first guide cavity 210 has only two openings: a first airflow inlet 211 and a first airflow outlet 212, to ensure that all the first branch airflow is introduced into the first branch air duct 51.

[0040] In order to form the second guide cavity 220, refer to Figure 1 , Figure 4 and Figure 5 As shown, the second guide channel 22 may further include a second guide wall 223 that blocks the flow between the main air duct 4 and the first branch air duct 51 to prevent the second branch airflow from flowing into the first branch air duct 51. When there are guide channels above and below the second guide channel 22, the second guide wall 223 can be connected to two adjacent partitions 23 to form a second guide cavity 220, so that the second guide cavity 220 has only two openings: the second airflow inlet 221 and the second airflow outlet 222, to ensure that all the second branch airflow is introduced into the second branch air duct 52. When the second guide channel 22 is located at the top or bottom of multiple guide channels, the second guide wall 223 can be connected to the top or bottom wall of the main air duct 4 and the adjacent partitions 23 to form a second guide cavity 220, so that the second guide cavity 220 has only two openings: the second airflow inlet 221 and the second airflow outlet 222, to ensure that all the second branch airflow is introduced into the second branch air duct 52.

[0041] In addition, in order to ensure the air velocity and air volume of the first air outlet 31 and the second air outlet 32, the first guide wall 213 can be tangentially connected between the main air duct 4 and the first branch air duct 51. That is, one side edge of the first guide wall 213 can be tangentially and sealed to the side wall of the main air duct 4, and the other side edge of the first guide wall 213 can be tangentially and sealed to the side wall of the first branch air duct 51, so that the first branch airflow can enter the first branch air duct 51 completely and smoothly from the main air duct 4, thereby reducing the velocity loss and flow loss when the first branch airflow enters the first branch air duct 51, and thus ensuring that the first air outlet 31 has sufficient air velocity and air volume. Alternatively, the second guide wall 223 can be tangentially connected between the main air duct 4 and the second branch air duct 52. That is, one edge of the second guide wall 223 can be tangentially and sealed to the side wall of the main air duct 4, and the other edge of the second guide wall 223 can be tangentially and sealed to the side wall of the second branch air duct 52. This allows the second branch airflow to enter the second branch air duct 52 completely and smoothly from the main air duct 4, thereby reducing the velocity and flow loss of the second branch airflow when entering the second branch air duct 52, and ensuring that the second air outlet 32 ​​has sufficient outlet velocity and outlet volume. Depending on the extension direction of the main air duct 4, the first branch air duct 51, and the second branch air duct 52, and their relative positions, the first guide wall 213 can also be tangentially connected between the main air duct 4 and the first branch air duct 51, while the second guide wall 223 is tangentially connected between the main air duct 4 and the second branch air duct 52.

[0042] To facilitate the diversion of airflow in the main duct 4 by the diversion section 2, refer to Figures 3 to 5 As shown, the mounting part 1 can be set at the intersection of the main air duct 4, the first branch air duct 51 and the second branch air duct 52. The diversion part 2 can be fixedly connected to the mounting part 1 and extend from the mounting part 1 into the three-way intersection formed by the main air duct 4, the first branch air duct 51 and the second branch air duct 52.

[0043] To simplify the internal structure of housing 3, refer to Figures 1 to 5 As shown, the mounting part 1 may include a first side 11 facing the first air distribution duct 51 and a second side 12 facing the second air distribution duct 52. The first side 11 may be constructed as a sidewall of the first air distribution duct 51, and the second side 12 may be constructed as a sidewall of the second air distribution duct 52. That is, when the mounting part 1 is connected to the housing 3, the first air distribution duct 51 and the second air distribution duct 52 can be formed simultaneously within the housing 3. Correspondingly, the first guide wall 213 may be smoothly connected to the first side 11 so that the first branch airflow smoothly enters the first air distribution duct 51, and the second guide wall 223 may be smoothly connected to the second side 12 so that the second branch airflow smoothly enters the second air distribution duct 52.

[0044] To strengthen the structure of the flow divider 2, refer to Figure 1 and Figure 2 As shown, multiple first guide channels 21 can be connected by vertically extending first reinforcing ribs 214, and multiple second guide channels 22 can be connected by vertically extending second reinforcing ribs 224. Specifically, the edges of multiple first guide walls 213 that abut against the sidewall of the main air duct 4 can be connected by first reinforcing ribs 214 to strengthen the first guide channels 21, and the edges of multiple second guide walls 223 that abut against the sidewall of the main air duct 4 can be connected by second reinforcing ribs 224 to strengthen the second guide channels 22.

[0045] According to a second aspect of the specific embodiments of this disclosure, an air conditioning indoor unit is provided, with reference to... Figures 3 to 5 As shown, the indoor unit of the air conditioner may include a housing 3, a fan 6, a heat exchanger 7, and the air duct diversion device in the above technical solution. The housing 3 is provided with a first air outlet 31 and a second air outlet 32. The housing 3 may also be provided with a main air duct 4, a first branch air duct 51, and a second branch air duct 52. The first branch air duct 51 can be fluidly connected between the main air duct 4 and the first air outlet 31, and the second branch air duct 52 can be fluidly connected between the main air duct 4 and the second air outlet 32. The fan 6 and the heat exchanger 7 are both disposed in the housing 3. The fan 6 can be constructed as a cross-flow fan. The fan 6 can blow airflow into the main air duct 4. The air duct diversion device can evenly divert the airflow in the main air duct 4 vertically to the first branch air duct 51 and the second branch air duct 52.

[0046] The air conditioning indoor unit provided in this disclosure has the same technical effect as the air duct diversion device in the above technical solution. To avoid unnecessary repetition, it will not be described in detail here.
