[0048] In this embodiment, the side plate assembly is specifically applied to the evaporator 1. The evaporator 1 is a V-shaped structure. A main side plate 21 and a first connecting side plate 22 connected to one end of the main side plate 21 are provided on one side of the evaporator 1. The main side plate 21 and the first connecting side plate 22 are arranged at a preset angle to form a V-shaped structure that is compatible with the end of the length direction of the evaporator 1. The side plate assembly of this embodiment includes the main side plate 21, the first connecting side plate 22, a base plate 31 and a shielding portion 32. The base plate 31 is arranged on one side of the main side plate 21. The shielding portion 32 The portion 32 is constructed on the base plate 31 and extends to the open portion 23 between the main side plate 21 and the first connecting side plate 22 to block the open portion 23. Therefore, the side plate assembly of this embodiment can block the hollow gap in the middle (V-shaped structure) of the right side of the evaporator through the shielding portion 32 constructed on the base plate 31 and extending to the open portion 23 between the main side plate 21 and the first connecting side plate 22, thereby preventing part of the wind from blowing directly out of the gap without passing through the evaporator when the cross-flow fan blades blow air, thereby improving the heat exchange efficiency of the air conditioner indoor unit.

[0049] Since the main side plate 21 is provided with a through hole for the copper tube of the evaporator 1 to pass through, the position where the substrate 31 blocks the through hole is also provided with a through hole for the copper tube to pass through, which facilitates the assembly of the evaporator 1. The inner diameter of the through hole on the substrate 31 is larger than the outer diameter of the copper tube.

[0052] In some embodiments, a first groove 222 is provided on the side of the overlapping portion 221 facing the shielding portion 32, and a first protrusion 321 adapted to the first groove 222 is provided on the side of the shielding portion 32 facing the overlapping portion 221; and / or a second protrusion is provided on the side of the overlapping portion 221 facing the shielding portion 32, and a second groove adapted to the second protrusion is provided on the side of the shielding portion 32 facing the overlapping portion 221.

[0053] In this embodiment, a first groove 222 is provided on the side of the overlapping portion 221 facing the shielding portion 32, and a first protrusion 321 matched with the first groove 222 is provided on the side of the shielding portion 32 facing the overlapping portion 221. By plugging and snapping the first groove 222 and the first protrusion 321, on the one hand, the positioning time during installation is improved, and the assembly efficiency is improved. On the other hand, when force is applied between the overlapping portion 221 and the shielding portion 32, the overlapping portion 221 and the shielding portion 32 will not be separated from each other, thereby improving the firm connection between the shielding portion 32 and the first connecting side plate 22 and preventing air leakage at the connection between the shielding portion 32 and the first connecting side plate 22.

[0054] In addition, a second protrusion may be provided on the side of the overlapping portion 221 facing the shielding portion 32, and a second groove matched with the second protrusion may be provided on the side of the shielding portion 32 facing the overlapping portion 221.

On the other hand, when force is applied between the overlapping portion 221 and the shielding portion 32, the overlapping portion 221 and the shielding portion 32 will not be separated from each other, thereby improving the firm connection between the shielding portion 32 and the first connecting side plate 22 and preventing air leakage at the connection between the shielding portion 32 and the first connecting side plate 22.

[0055] The first groove 222 , the first protrusion 321 , the second protrusion and the second groove can all be manufactured by stamping.

[0056] In some embodiments, the overlapping portion 221 and the shielding portion 32 are locked by at least two locking members 4;

[0057] The first protrusion 321 is located between two adjacent locking members 4; and / or,

[0058] The second protrusion is located between two adjacent locking members 4 .

[0059] In this embodiment, the overlapping portion 221 and the shielding portion 32 are locked by at least two locking members 4, so that the connection between the overlapping portion 221 and the shielding portion 32 is more secure and air leakage is prevented at the connection between the shielding portion 32 and the first connecting side plate 22; the first protrusion 321 can be arranged between two adjacent locking members 4, which is beneficial to the positioning of the hole through which the locking member 4 is penetrated, and the assembly efficiency is improved;

[0060] In addition, the second protrusion may also be arranged between two adjacent locking members 4, so as to facilitate the positioning of the holes through which the locking members 4 are formed and improve the assembly efficiency.

[0061] In the related art, the indoor unit relies solely on the heat of the refrigerant, which is not comfortable enough and needs to rely on the electric auxiliary heating device 6 to increase the heat. The angle of the evaporator 1 is the best installation position for the electric auxiliary heating device 6. One end of the electric auxiliary heating device 6 is fixed to the left bracket 5 with a screw 8, and the right side is not fixed and is unreliable. It is only fixed to the electrical box by pulling with the lead 62 of the electric auxiliary heating device 6. This method causes the electric auxiliary heating device 6 to fall off easily.

[0062] In some embodiments, one end of the evaporator 1 away from the main side plate 21 is connected to the left bracket 5, an electric auxiliary heating device 6 is arranged in the V-shaped structure of the evaporator 1, one end of the electric auxiliary heating device 6 is connected to the left bracket 5, and a first insertion hole 322 is provided on the shielding portion 32 for the electric auxiliary heating device 6 to be inserted toward one end of the main side plate 21.

[0063] In this embodiment, one end of the evaporator 1 away from the main side plate 21 is connected to the left bracket 5, and is specifically fixed by using screws 8.

In this embodiment, a first insertion hole 322 for inserting the electric auxiliary heating device 6 toward one end of the main side plate 21 is provided on the shielding portion 32, so that the electric auxiliary heating device 6 can be prevented from falling toward one end of the main side plate 21, thereby improving the reliability of the product.

[0064] In some embodiments, the side wall of the first insertion hole 322 is provided with a make way groove 323 that penetrates the depth of the first insertion hole 322, and the peripheral arm of the electric auxiliary heating device 6 at one end facing the main side plate 21 is provided with a clamping protrusion 61, and the clamping protrusion 61 can be clamped on the side of the shielding portion 32 away from the left bracket 5 through the make way groove 323.

[0065] In this embodiment, a clearance groove 323 is provided on the side wall of the first insertion hole 322 and penetrates the depth of the first insertion hole 322, and a clamping protrusion 61 is provided on the peripheral arm of the end of the electric auxiliary heating device 6 facing the main side plate 21. During installation, the clamping protrusion 61 is extended from the side of the shielding portion 32 close to the left bracket 5 to the side of the shielding portion 32 away from the left bracket 5 through the clearance groove 323, and the electric auxiliary heating device 6 is rotated by a certain angle so that the clamping protrusion 61 is clamped on the side of the shielding portion 32 away from the left bracket 5, thereby preventing the end of the electric auxiliary heating device 6 facing the main side plate 21 from detaching from the first insertion hole 322, thereby improving the reliability of the product.

[0066] In some embodiments, a grounding wire connection portion 311 is configured on a side of the substrate 31 away from the shielding portion 32 , and the grounding wire connection portion 311 is bent and extends along the length direction of the evaporator 1 .

[0067] In this embodiment, a grounding wire connection portion 311 is constructed on the side of the substrate 31 away from the shielding portion 32. The grounding wire connection portion 311 is bent and extended along the length direction of the evaporator 1. The grounding wire of the substrate 31 prevents the side plate assembly from being electrified, thereby improving the safety of the product.

[0068] In some embodiments, a motor pressing plate 7 is provided at one side of the evaporator 1 , and the motor pressing plate 7 has a buckle 71 . A hanging hole 324 for the buckle 71 to be inserted and engaged is opened on the shielding portion 32 .

[0069] In this embodiment, the shielding portion 32 is provided with a mounting hole 324 for the buckle 71 to be inserted and engaged, thereby improving the reliability of the connection between the side plate assembly and the motor pressure plate 7.

[0070] In some embodiments, a reinforcing rib 312 is constructed at the connection between the substrate 31 and the shielding portion 32. The reinforcing rib 312 improves the strength of the connection between the substrate 31 and the shielding portion 32. The reinforcing rib 312 can be manufactured by stamping.

[0071] In some embodiments, the side of the substrate 31 facing the shielding portion 32 and the side of the shielding portion 32 facing the substrate 31 are both constructed with flanges 313. During specific assembly, the leads of the electric auxiliary heating device 6 are generally led out from the connection between the side of the substrate 31 facing the shielding portion 32 and the side of the shielding portion 32 facing the substrate 31. Constructing the flange 313 here can prevent burrs and other cutting lines.
