For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] The air conditioner indoor unit 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0042] like Figure 1 and Figure 2 As shown, the air-conditioning indoor unit 100 according to the embodiment of the present invention includes a chassis 1 and a left support 2 .

[0043] Specifically, refer to the attached Figure 3 and attached Figure 5As shown, the chassis 1 can protect the internal structure of the air-conditioning indoor unit 100, reduce damage to the air-conditioning indoor unit 100, and help extend the service life of the air conditioner. An end plate 11 is provided at the left end of the chassis 1, and the heat exchanger 4 of the air-conditioning indoor unit 100 is provided on the right side of the end plate 11.

[0044] Further, see Attachment Figure 3 and attached Figure 4 As shown, the left support 2 is arranged at the left end of the chassis 1 and on the right side of the end plate 11, and is used to support the left end of the heat exchanger 4, so that the heat exchanger 4 can be firmly fixed in the air conditioner indoor unit 100, ensuring that the heat exchanger 4 can operate stably under various working conditions, and preventing distortion caused by vibration or external force. In addition, the left support 2 can also help balance the weight and potential energy of the pipeline and equipment, reduce the load on the heat exchanger 4, and thus protect the heat exchanger 4 from excessive external force damage. Further, refer to the attached Figure 7 , Attachment Figure 8 and attached Fig.10 As shown, the left side of the left support 2 has an extension plate 21 protruding to the left, the left end of the extension plate 21 is not provided with an upwardly protruding upper flange, and the upper surface of the extension plate 21 is lower than the upper end surface of the end plate 11.

[0045] In the prior art, the left end of the extension plate is provided with an upwardly protruding upper flange. When the air conditioner indoor unit is in cooling mode, condensation water is usually easily generated on the surface of the left support. The setting of the upper flange can limit the condensation water and collect the generated condensation water on the extension plate to prevent the condensation water from flowing to the outside of the chassis. However, the processing of the left support in the prior art is complicated, and a large inclined top needs to be added to the mold to process the upper flange. The addition of a new large inclined top will greatly increase the mold cost, affect the cooling effect of the cooling water during the processing, and extend the injection molding cycle, making the production and processing cost of the left support high and the efficiency low. In addition, the large inclined top is not easy to maintain during the production process, which further increases the cost of the mold itself.

[0046] like Figure 8 , Fig.10 and Fig.11 As shown, the left support 2 of the utility model does not need the upper flange in the prior art, but by increasing the height of the end plate 11, the upper surface of the extension plate 21 is lower than the upper end surface of the end plate 11, and the end plate 11 is used to achieve the limiting effect of the upper flange in the prior art to prevent condensation water from overflowing from the chassis 1. The design of canceling the upper flange can reduce the structural complexity of the left support 2, and there is no need for a large inclined top on the mold in the prior art, thereby reducing the cost of the mold and the production and processing cost of the left support 2, making the cooling and transporting water on the mold relatively uniform, ensuring the cooling effect of the cooling and transporting water during the processing, shortening the injection molding cycle, improving the production efficiency of the left support 2, facilitating the maintenance of the mold, and reducing the cost of the mold itself.

[0047] It should be noted that the upper end surface of the end plate 11 is higher than the upper surface of the extension plate 21. Compared with the end plate in the prior art, the end plate 11 of the utility model is Figure 4 The height of the end plate 11 is increased, the end plate 11 can be directly an integral part, and the end plate 11 can also have a rib added on the original basis, the rib can increase the height of the end plate 11, and play a role in shielding condensation water.

[0048] According to the air-conditioning indoor unit 100 of the embodiment of the utility model, an end plate 11 is provided at the left end of the chassis 1, and a left support 2 is provided at the left end of the chassis 1 and is located on the right side of the end plate 11. The left side of the left support 2 has an extension plate 21 protruding to the left, and the left end of the extension plate 21 is not provided with an upper flange protruding upward. The upper surface of the extension plate 21 is lower than the upper end surface of the end plate 11. By increasing the height of the end plate 11, condensation water on the surface of the left support 2 can be prevented from overflowing from the chassis 1, thereby reducing the structural complexity of the left support 2, reducing the production and processing cost of the left support 2, ensuring the cooling effect of cooling water during the production and processing, shortening the injection molding cycle of the left support 2, and improving the production efficiency of the left support 2.

[0049] In some embodiments of the present invention, refer to the attached Figure 6 and attached Figure 7 As shown, the right side surface of the end plate 11 is separated from the left side surface of the extension plate 21. When the air-conditioning indoor unit 100 is in cooling mode, condensation water is easily generated on the surface of the left support 2. The condensation water can flow from the gap between the right side surface of the end plate 11 and the left side surface of the extension plate 21 to the chassis 1, which is convenient for the discharge of the condensation water.

[0050] In a further embodiment of the present invention, refer to the attached Figure 8 As shown, the left end of the extension plate 21 is provided with a downwardly protruding lower flange 211. The setting of the lower flange 211 can improve the structural strength of the extension plate 21, thereby enhancing the structural stability of the left support 2. It should be noted that compared with the upper flange in the prior art, the lower flange 211 of the utility model can be injection molded according to the slider structure in the mold, without adding additional components to the mold, thereby making the lower flange 211 simple to process and convenient to produce, thereby reducing the production and processing costs of the left support 2.

[0051] In some embodiments of the present invention, refer to the attached Figure 8 and attached Fig. 9 As shown, the front end of the extension plate 21 has a guide portion 212, which extends from the rear to the front (eg Figure 8As shown in the figure, the guide part 212 is inclined downward. When the air-conditioning indoor unit 100 is in cooling mode, condensation water is easy to form on the surface of the left support 2. The condensation water can flow along the guide part 212 to the chassis 1, which is convenient for the discharge of condensation water, avoids affecting the service life of the air-conditioning indoor unit 100, and reduces the maintenance frequency of the air-conditioning indoor unit 100.

[0052] It should be noted that the reference Figure 7 and attached Figure 8 As shown, the condensation water on the surface of the left support 2 can flow to the chassis 1 along the guide portion 212, or flow to the chassis 1 through the gap between the right side surface of the end plate 11 and the left side surface of the extension plate 21. The setting of the two flow paths can increase the flow speed of the condensation water and avoid excessive condensation water remaining on the surface of the extension plate 21.

[0053] In some embodiments of the present invention, refer to the attached Figure 2 As shown, the air-conditioning indoor unit 100 also includes a wind wheel 3, and a supporting space for supporting the rotating axis of the wind wheel 3 is defined between the end plate 11 and the left support 2. The extension plate 21 has an upwardly protruding protrusion 213, and the protrusion 213 and the supporting space are arranged relative to each other in the up and down directions to avoid the rotating axis of the wind wheel 3 and prevent the extension plate 21 from interfering with the normal rotation of the wind wheel 3, thereby ensuring the normal operation of the air-conditioning indoor unit 100.

[0054] In a further embodiment of the present invention, refer to the attached Figure 2 As shown, the upper surface of the protrusion 213 is an arc surface. On the one hand, the protrusion 213 is designed as an arc surface to match the shape of the rotating shaft of the wind wheel 3 to better avoid the rotating shaft of the wind wheel 3. On the other hand, the arc surface can accelerate the flow of condensation water to avoid condensation water remaining on the protrusion 213, so that the condensation water flows from the protrusion 213 to other places of the extension plate 21, which is convenient for the condensation water to flow to the chassis 1, thereby avoiding affecting the service life of the air-conditioning indoor unit 100 and reducing the maintenance frequency of the air-conditioning indoor unit 100.

[0055] In a further embodiment of the present invention, refer to the attached Figure 8 As shown, along the front-to-back direction (such as Figure 8 As shown), the extension plate 21 includes a first plate 214 and a second plate 215 which are located on both sides of the protrusion 213 and are horizontally arranged. The first plate 214 is located on the rear side of the second plate 215. The height of the first plate 214 is higher than that of the second plate 215. The condensation water remaining on the protrusion 213 can flow to the first plate 214 or the second plate 215. Since the height of the first plate 214 is higher than that of the second plate 215, the condensation water finally gathers at the first plate 214, which facilitates the condensation water to flow to the chassis 1, avoids affecting the service life of the air-conditioning indoor unit 100, and reduces the maintenance frequency of the air-conditioning indoor unit 100.

[0056] In some embodiments of the present invention, refer to the attached Figure 3 and attached Figure 8 As shown, the left support 2 is connected to the chassis 1 by fasteners, which can ensure the reliability and stability of the connection between the left support 2 and the chassis 1, and facilitate the connection and disassembly of the left support 2 and the chassis 1, and facilitate the assembly and disassembly of the air conditioner indoor unit 100, reduce the maintenance difficulty of the air conditioner indoor unit 100, and improve the maintenance efficiency of the air conditioner indoor unit 100. Specifically, refer to the attached Figure 3 and attached Figure 8 As shown, both the first plate 214 and the second plate 215 are provided with mounting holes 216 , and fasteners are passed through the mounting holes 216 and fixed to the chassis 1 , so as to achieve the fixation of the left support 2 and the chassis 1 .

[0057] In some embodiments of the present invention, refer to the attached Figure 3 and attached Figure 8 As shown, at least one of the two ends of the left support 2 in the front-to-back direction is connected to the chassis 1 by a clamping connection, which can ensure the reliability and stability of the connection between the left support 2 and the chassis 1, facilitate the disassembly and replacement of the left support 2, facilitate the assembly and disassembly of the air-conditioning indoor unit 100, reduce the maintenance difficulty of the air-conditioning indoor unit 100, and improve the maintenance efficiency of the air-conditioning indoor unit 100. Specifically, refer to the attached Figure 3 and attached Figure 8 As shown, a hook 22 is provided at the rear end of the left support 2 , and the hook 22 is clamped on the chassis 1 .
