Therefore, the embodiments are not limited except by the limitations imposed by the appended claims and their equivalents. Furthermore, various modifications and changes can be made within the scope of the appended claims.

[0032] This application provides a mounting bracket 1 for an air conditioner indoor unit, such as...Figures 2-8 As shown, the fixed frame 1 is arranged for mounting a filter screen. The upper end surface of the fixed frame 1 is provided with a first water collecting groove 11, which is arranged to collect water splashed after dropping from the elbow joint portion 21 of the heat exchanger 2 of the air conditioner indoor unit.

[0033] In the air conditioner indoor unit, the fixed frame 1 is used for mounting a filter screen, which can filter the air entering the air inlet of the air conditioner indoor unit. The fixed frame 1 and the heat exchanger 2 can be fixed in the shell of the air conditioner indoor unit, and the fixed frame 1 is arranged close to the lower part of the heat exchanger 2. The heat exchanger 2 can be a tube-fin heat exchanger, and the condensed water on the elbow joint portion 21 of the heat exchanger 2 will splash onto the upper end surface of the fixed frame 1 after dropping. Therefore, in the embodiment of the present application, the first water collecting groove 11 is arranged on the upper end surface of the fixed frame 1, which can collect the water splashed after dropping from the elbow joint portion 21 of the heat exchanger 2, so as to avoid the water on the elbow joint portion 21 of the heat exchanger 2 from flowing out of the air conditioner indoor unit after splashing onto the fixed frame 1, thereby causing the air conditioner indoor unit to drip water and affecting the use performance of the air conditioner indoor unit.

[0034] In some example embodiments, as shown in Figures 2-5 The first water collecting groove 11 is arranged on the side of the fixed frame 1 close to the elbow joint portion 21 of the heat exchanger 2.

[0035] The water on the elbow joint portion 21 of the tube-fin heat exchanger will drop and splash onto the fixed frame 1, so the first water collecting groove 11 is arranged on the side of the fixed frame 1 close to the elbow joint portion 21 of the heat exchanger 2, so that the water splashed onto the fixed frame 1 can be collected in the first water collecting groove 11, thereby preventing the water splashed onto the fixed frame 1 from flowing out of the air conditioner indoor unit.

[0036] In some example embodiments, as shown in Figures 2-5 One end of the first water collecting groove 11 is arranged to extend to overlap the fin portion 22 of the heat exchanger 2, and the other end of the first water collecting groove 11 is arranged to extend beyond the elbow joint portion 21.

[0037] Along the length direction of the first water collecting groove 11, one end of the first water collecting groove 11 can extend to overlap the fin portion 22 of the tube-fin heat exchanger, and the other end of the first water collecting groove 11 can extend beyond the elbow joint portion 21, so that the length of the first water collecting groove 11 is long enough to allow as much water as possible splashed onto the fixed frame 1 to fall into the first water collecting groove 11, thereby preventing the water from flowing from the fixed frame 1 to the outside of the air conditioner indoor unit.

[0038] In some example embodiments, as shown in Figure 3 and Figure 5As shown, the first water collecting groove 11 comprises a first groove portion 131 and a second groove portion 132 which are in communication, the first groove portion 131 is arranged to correspond to the elbow joint portion 21 of the heat exchanger 2, the second groove portion 132 is arranged to correspond to the fin portion 22 of the heat exchanger 2, and the width of the first groove portion 131 is greater than the width of the second groove portion 132. The first groove portion 131 and the second groove portion 132 are both rectangular grooves.

[0039] The first water collecting groove 11 comprises a first groove portion 131 corresponding to the elbow joint portion 21 of the heat exchanger 2 (e.g., corresponding in the front-rear direction) and a second groove portion 132 corresponding to the fin portion 22 of the heat exchanger 2 (e.g., corresponding in the front-rear direction), the first groove portion 131 and the second groove portion 132 are in communication, and the width of the first groove portion 131 is greater than the width of the second groove portion 132. Since the first water collecting groove 11 is mainly used to collect the water dripping from the elbow joint portion 21 of the heat exchanger 2 and splashing onto the fixed frame 1, the width of the first groove portion 131 corresponding to the elbow joint portion 21 of the heat exchanger 2 is set to be greater than the width of the second groove portion 132, which is conducive to the splashing water to be more collected in the first water collecting groove 11. Of course, the width of the second groove portion 132 can be set to be equal to the width of the first groove portion 131.

[0040] As shown in some example embodiments, Figure 3 , Figure 5 and Figure 8 , the groove wall of the first water collecting groove 11 is provided with a drain port 12.

[0041] The drain port 12 is arranged on the groove wall of the first water collecting groove 11, so that the water collected in the first water collecting groove 11 can be drained out of the drain port 12, preventing the water from overflowing in the first water collecting groove 11 and flowing to the outside of the air conditioner indoor unit, and also avoiding the breeding of bacteria in the first water collecting groove 11, affecting the use performance of the air conditioner.

[0042] As shown in some example embodiments, Figure 3 and Figure 5 , the drain port 12 is arranged on the first side wall 111 of the first water collecting groove 11, and the first side wall 111 is arranged to be located on the side of the first water collecting groove 11 close to the heat exchanger 2.

[0043] The drain port 12 is arranged on the first side wall 111 of the first water collecting groove 11 close to the heat exchanger 2, so that the drain port 12 is close to the inside of the air conditioner indoor unit, so that the water drained out of the drain port 12 can fall into the second water collecting groove 31 (see the description below) of the bottom plate 3 of the air conditioner indoor unit.

[0044] As shown in some example embodiments, Figure 8As shown, the bottom surface 121 of the drain opening 12 gradually slopes downward along a direction from the inner wall surface of the first side wall 111 to the outer wall surface, and the bottom surface 121 of the drain opening 12 is not higher than the bottom surface of the first water collecting groove 11.

[0045] As shown, the bottom surface 121 of the drain opening 12 gradually slopes downward along a direction from the inner wall surface of the first side wall 111 to the outer wall surface, and the bottom surface 121 of the drain opening 12 is not higher than the bottom surface of the first water collecting groove 11.

[0046] The embodiments of the present application also provide an air conditioner indoor unit, as shown in Figures 2-8 As shown, the bottom surface 121 of the drain opening 12 gradually slopes downward along a direction from the inner wall surface of the first side wall 111 to the outer wall surface, and the bottom surface 121 of the drain opening 12 is not higher than the bottom surface of the first water collecting groove 11.

[0047] As shown, the bottom surface 121 of the drain opening 12 gradually slopes downward along a direction from the inner wall surface of the first side wall 111 to the outer wall surface, and the bottom surface 121 of the drain opening 12 is not higher than the bottom surface of the first water collecting groove 11.

[0048] As shown in some exemplary embodiments, Figure 8 As shown, the bottom surface 121 of the drain opening 12 gradually slopes downward along a direction from the inner wall surface of the first side wall 111 to the outer wall surface, and the bottom surface 121 of the drain opening 12 is not higher than the bottom surface of the first water collecting groove 11.

[0049] As shown, the bottom surface 121 of the drain opening 12 gradually slopes downward along a direction from the inner wall surface of the first side wall 111 to the outer wall surface, and the bottom surface 121 of the drain opening 12 is not higher than the bottom surface of the first water collecting groove 11.

[0050] In some exemplary embodiments, the heat exchanger 2 is a tube-fin heat exchanger, and the heat exchange tube thereof can be a copper tube or other materials.

[0051] As shown in some exemplary embodiments, Figure 2As shown, the air conditioner indoor unit further comprises a panel 5 fixed to the front side of the face frame 4. The panel 5 and the face frame 4 can be an integral structure. Of course, the face frame 4 and the panel 5 can also be provided as a split type fixed structure.
