[0045] Please combine Figure 1 , Figure 2 and Fig. 9 As shown, according to an embodiment of the present invention, an air conditioner indoor unit 200 is proposed, the air conditioner indoor unit 200 includes an electric control component 100 and a chassis shell, the electric control component 100 is arranged in the chassis shell of the air conditioner indoor unit 200, the chassis shell includes a side plate 201, a bottom plate and a top plate 202 connected to each other, the side plate 201, the top plate 202 and the bottom plate together form a rectangular parallelepiped structure, the side plate 201 includes a first side plate 2011, a second side plate 2012, a third side plate 2013 connected in sequence, Side panel 2013 and fourth side panel 2014, specifically, an air duct fixing plate 203 is also provided in the chassis shell, the air duct fixing plate 203 is arranged parallel to the top panel 202, and the air duct fixing plate 203 is respectively connected to the first side panel 2011, the second side panel 2012 and the fourth side panel 2014 to form a space for accommodating the electric control component 100 between the first side panel 2011, the second side panel 2012, the fourth side panel 2014, the air duct fixing plate 203 and the top panel 202.

[0046] In this embodiment, the electric control assembly 100 includes a first mounting plate 10 and an electric control panel 20, the electric control panel 20 has an operable surface 21, and a wiring terminal digital display device is arranged on the operable surface 21, the first mounting plate 10 is connected to the side panel 201 or the top panel 202, or the first mounting plate 10 is connected to the side panel 201 and the top panel 202 at the same time, and the first mounting plate 10 has a first mounting surface 121 inclined relative to the side panel 201, and the electric control panel 20 is installed on the first mounting surface 121, so that the electric control panel 20 is inclined relative to the side panel 201, so that there is an operable space between the operable surface 21 on the electric control panel 20 and the side panel 201, so as to facilitate the plug-in and unplug wiring operation of the electric control panel 20, and to more conveniently observe the data displayed by the digital display device outside the chassis shell. In this embodiment, the first mounting surface 121 is arranged vertically with the top panel 202 and the air duct fixing plate 203.

[0047] In other embodiments, the first mounting surface 121 can be set to be inclined relative to the top plate 202 and the air duct fixing plate 203, so that the electric control board 20 is inclined relative to the top plate 202 and the air duct fixing plate 203, and the operable surface 21 of the electric control board 20 is set toward the first side panel 2011 and the top plate 202, so that there is an operable space between the operable surface 21 on the electric control board 20 and the first side panel 2011 or between the operable surface 21 and the top plate 202, so as to facilitate the plugging and unplugging and wiring operations of the electric control board 20, and more conveniently observe the data displayed by the digital display device outside the chassis shell.

[0048] It should be noted that the location and manner of setting the first mounting plate 10 and the first mounting surface 121 in the chassis shell can be adjusted according to the placement of the chassis shell in actual use and the manner of setting the assembly or maintenance window, so that the operable surface 21 of the electric control board 20 can face the operator. For example, when the operator needs to remove the first side panel 2011 or set a maintenance or assembly window on the first side panel 2011, the first mounting surface 121 is set to be tilted relative to the first side panel 2011, so that the operable surface 21 of the electric control board 20 can face the operator. When the operator needs to remove the top panel 202 or set a maintenance or assembly window on the top panel 202, the first mounting surface 121 is set to be tilted relative to the top panel 202, so that the operable surface 21 of the electric control board 20 can face the operator.

[0049] In some embodiments of the present invention, please combine Figure 2 , Figure 3 and Figure 7As shown, the electric control assembly 100 further includes a first electronic component 31, and the first mounting board 10 is further provided with a second mounting surface 141, and the second mounting surface 141 is used to mount the first electronic component 31. Specifically, the second mounting surface 141 is located on the side of the first mounting surface 121 away from the electric control board 20. In detail, the first mounting surface 121 is on the first plane 105, and a first mounting space 101 is provided between the second mounting surface 141 and the first plane 105 in a direction perpendicular to the first plane 105. The first electronic component 31 is located in the first mounting space 101, so as to make full use of the space on the side of the first mounting surface 121 away from the electric control board 20, so as to make the structure of the electric control assembly 100 more compact.

[0050] For example, in a specific embodiment, when the first mounting plate 10 is mounted on the second side plate 2012, and the first mounting surface 121 is inclined relative to the first side plate 2011 and the second side plate 2012, along the direction perpendicular to the first side plate 2011 and from the outside to the inside of the chassis shell, the distance between the first plane 105 where the first mounting surface 121 is located and the second side plate 2012 gradually increases, so that an installation space is formed between the first plane 105 and the second side plate 2012. In this embodiment, the first mounting plate 10 is located between the second side plate 2012 and the electric control board 20. Therefore, the second mounting surface 141 is arranged on the first mounting surface 121 away from the electric control board. When the second mounting surface 141 is on one side of the electric control board 20, the second mounting surface 141 is located between the first plane 105 and the second side plate 2012. Therefore, the first mounting space 101 formed between the second mounting surface 141 and the first plane 105 is also located in the space between the first plane 105 and the second side plate 2012. The second electronic component is mounted on the second mounting surface 141 and located in the first mounting space 101, which can make full use of the space between the first plane 105 and the second side plate 2012, and the second mounting surface 141 and the first electronic component 31 are located on the side of the electric control board 20 away from the operable surface 21, so as to prevent the second electronic component 32 from blocking the operable surface 21. In this embodiment, the second mounting surface 141 is arranged parallel to the first mounting surface 121.

[0051] In some embodiments, the second mounting surface 141 has a first projection on the first plane 105 along a direction perpendicular to the first plane 105, and the first projection is spaced apart from the first mounting surface 121, that is, the first projection of the first mounting surface 121 and the second mounting surface 141 are respectively located in different areas on the first plane 105, to prevent interference between the first electronic component 31 and the first mounting surface 121 along a direction perpendicular to the first plane 105.

[0052] The electric control board 20 includes a first partial area and a second partial area. The first partial area of ​​the electric control board 20 is connected to the first mounting surface 121, and the second partial area of ​​the electric control board 20 extends from the first mounting surface 121. In a direction perpendicular to the first plane 105, the first electronic component 31 has a second projection on the first plane 105, and the second partial area of ​​the electric control board 20 has a third projection on the first plane 105. At least part of the second projection coincides with the third projection, and at least part of the second partial area is stacked with the second mounting surface 141, so that the overall structure of the electric control assembly 100 is more compact.

[0053] It should be noted that the positional relationship between the first projection and the first mounting surface 121 is related to the angle between the operable surface 21 of the electric control board 20 and the assembly or maintenance window and the size of the first electronic component 31 .

[0054] For example, Figure 6 As shown, if one side of the first side panel 2011 is used as an assembly window, or the first side panel 2011 is used as a detachable maintenance window, the first mounting plate 10 is mounted on the second side panel 2012, and the first mounting surface 121 is inclined relative to the first side panel 2011 and the second side panel 2012, and the electric control board 20 is mounted on the first mounting surface 121. Generally, the electric control board 20 is arranged parallel to the first mounting surface 121. When the internal space of the chassis shell is limited, it is necessary to set the angle between the operable surface 21 of the electric control board 20 and the first side panel 2011 to a larger angle (for example, 60°), and the operable surface The angle (30°) between the first plane 105 and the second side panel 2012 is relatively small. If the size of the first electronic component 31 along the first direction perpendicular to the first direction (i.e., along the direction perpendicular to the first side panel 2011 and from the outside to the inside of the chassis shell) is large, the space between the first plane 105 and the second side panel 2012 is relatively narrow. In order to obtain sufficient installation space between the first plane 105 and the second side panel 2012, the second mounting surface 141 is made as far away from the first mounting surface 121 as possible in the direction parallel to the first plane 105, so that the first projection is spaced apart from the first mounting surface 121.

[0055] Understandably, in other embodiments, along the direction perpendicular to the second side panel 2012, there is a larger space inside the chassis shell, and it is necessary to set the angle between the operable surface 21 of the electric control board 20 and the first side panel 2011 to a smaller angle (for example, 30°), and the angle between the operable surface 21 and the second side panel 2012 (60°) is relatively larger. When the size of the first electronic component 31 along the direction perpendicular to the first direction remains unchanged, the space between the first plane 105 and the second side panel 2012 is relatively wide. Along the direction perpendicular to the first plane 105, even if the second mounting surface 141 and the first mounting surface 121 are stacked so that at least part of the first projection overlaps with the first mounting surface 121, sufficient mounting space can still be obtained between the first plane 105 and the second side panel 2012 to accommodate the first electronic component 31, so that at least part of it can overlap with the first mounting surface 121.

[0056] Furthermore, please combine Figure 2 , Figure 6 and Figure 7 As shown, the first mounting board 10 further includes a third mounting surface 151, which is adjacent to the second mounting surface 141 and is located on the side of the second mounting surface 141 away from the first mounting surface 121, and the electric control assembly 100 further includes a second electronic component 32, which is mounted on the third mounting surface 151. In detail, based on the fact that the second mounting surface 141 is arranged on the side of the first mounting surface 121 away from the electric control board 20, and the second mounting surface 141 is spaced apart from the first plane 105 and forms the first mounting space 101, so that the side of the first mounting space 101 away from the first mounting surface 121 forms a second mounting space that can accommodate other electronic components, therefore, the third mounting surface 151 is further arranged on the side of the second mounting surface 141 away from the first mounting surface 121, and the third mounting surface 151 is arranged perpendicular to the first plane 105, and the second electronic component 32 is mounted on the third mounting surface 151, so that the space in the chassis shell can be fully utilized, so that the electric control assembly 100 has a higher degree of integration and a more compact structure.

[0057] In some embodiments of the present invention, Figure 6 and Figure 7 As shown, the first mounting plate 10 includes a first connecting plate body 11, a first plate body 12, a second plate body 13, a third plate body 14, a fourth plate body 15 and a second connecting plate body 16 which are connected in sequence. The first mounting plate 10 is an integral plate-like member formed by a sheet metal bending process, and any two adjacent ones of the first connecting plate body 11, the first plate body 12, the second plate body 13, the third plate body 14, the fourth plate body 15 and the second connecting plate body 16 are arranged at an angle.

[0058] Specifically, a mounting hole is provided on the first connecting plate body 11, and the first connecting plate body 11 is connected to the second side plate 2012 by connecting parts such as bolts. The first connecting plate body 11 is tilted relative to the first plate body 12. When the first connecting plate body 11 is connected to the second side plate 2012, the plate surface of the first connecting plate body 11 fits with the second side plate 2012, so that the connection structure between the first mounting plate 10 and the second side plate 2012 is more stable, and the first plate body 12 is tilted relative to the second side plate 2012. The first mounting surface 121 is provided on a side of the first plate body 12 away from the second side plate 2012, so that the first mounting surface 121 faces the first side plate 2011, and the first mounting surface 121 is tilted relative to the first side plate 2011.

[0059] The angle between the second plate body 13 and the first plate body 12 is greater than 90° and less than 180°, and the third plate body 14 is parallel to the first plate body 12, the second mounting surface 141 is arranged on a side of the third plate body 14 facing the first plane 105, the fourth plate body 15 is arranged perpendicular to the third plate body 14, the second connecting plate body 16 is arranged perpendicular to the fourth plate body 15, and the second connecting plate body 16 and the first plate body 12 are located on the first plane 105 together, and mounting holes are provided on the first plate body 12 and the second connecting plate body 16, a first part of the electric control board 20 is installed on the first plate body 12 by bolts and other connecting parts, and a second part of the electric control board 20 is installed on the second connecting plate by bolts and other connecting parts.

[0060] In this embodiment, if Figure 6 and Figure 7 As shown, the first mounting plate 10 is formed with mounting planes for mounting electronic components at multiple positions, such as the first mounting surface 121, the second mounting surface 141 and the third mounting surface 151, by a sheet metal bending process. On the one hand, the sheet metal bending process is simple to process, and the first mounting plate 10 is integrally formed, which simplifies the assembly procedure and reduces the difficulty of assembly. On the other hand, the first mounting surface 121, the second mounting surface 141 and the third mounting surface 151 are respectively located in different spaces, making the overall structure of the electronic control assembly 100 more compact, and the electronic control board 20, the first electronic control component and the second electronic control component are respectively located in different spaces to avoid mutual interference.

[0061] It should also be noted that the first mounting surface 121, the second mounting surface 141 and the third mounting surface 151 are all inclined relative to the first side plate 2011 and the second side plate 2012 to facilitate the plugging and unplugging operations of the wiring on the electric control board 20, the first electronic component 31 and the second electronic component 32.

[0062] In this embodiment, if Figure 6 and Figure 7As shown, the angle between the first connecting plate body 11 and the first plate body 12 is the first angle, the angle between the first plate body 12 and the second plate body 13 is the second angle, and the angle between the second plate body 13 and the third plate body 14 is the third angle. The first angle is greater than the second angle, and the second angle is equal to the third angle. Along the direction perpendicular to the first side plate 2011 and from the outside to the inside of the chassis housing (i.e., the first direction shown in Figure 6), the dimension of the first mounting plate 10 in the direction perpendicular to the second side plate 2012 gradually increases. Thus, on the premise of ensuring that the operable surface 21 of the electronic control board 20 is inclined relative to the first side plate 2011 and an operation space for the operator to plug and unplug the wiring is formed between the operable surface 21 and the first side plate 2011, the first mounting plate 10 can make full use of the space between the first plane 105 and the second side plate 2012.

[0063] In this embodiment, please refer to Figure 1 、 Figure 7 and Fig. 9 As shown, the first mounting plate 10 further includes a flanging portion 122. The flanging portion 122 is provided at the edge of the first plate body 12 on the side facing the top plate 202. The flanging portion 122 is plate-shaped, and at least one mounting hole is provided on the flanging portion 122. The flanging portion 122 is connected to the top plate 202 through a connecting member such as a bolt passing through the mounting hole, so that the electronic control assembly 100 is more firmly fixed in the chassis housing.

[0064] In some embodiments of the present invention, as Figure 6 and Figure 7 shown, the electronic control assembly 100 further includes a bow-shaped plate 50. The bow-shaped plate 50 is generally in the shape of a "several" character. The bow-shaped plate 50 includes a bowed portion 51 and a first connecting portion 52 and a second connecting portion 53 connected to the bowed portion 51. The first connecting portion 52 and the second connecting portion 53 are welded to the third plate body 14.
