The outer side of the tube sheet 310 is provided with a water baffle 40, and the water baffle 40 includes a first water retaining portion 410, and the first water retaining portion 410 is located on the upper side of the bearing seat 20. When the air conditioner indoor unit 100 is running, the heat exchanger generates condensate water, which flows downward along the tube sheet 310 or directly drips downward. The first water retaining portion 410 of the water baffle 40 is arranged on the upper side of the bearing seat 20, and when the condensate water drips downward, it drips onto the upper surface of the first water retaining portion 410 and flows along the upper surface of the first water retaining portion 410. By providing the water baffle 40, the condensate water is prevented from dripping onto the bearing seat 20 and corroding the interior of the bearing seat 20, thereby avoiding affecting the service life of the bearing. Moreover, by providing the water baffle 40, the condensate water is prevented from dripping onto the bearing seat 20, preventing the growth of bacteria and mold, thereby avoiding affecting the indoor air quality and threatening the health of the user.

[0041] In some embodiments of the utility model, as Figure 1 indicated, the first water retaining portion 410 is inclined upward from front to back.

[0042] In some embodiments of the utility model, as shown in Figure 2 and Figure 3 As shown, the lower side surface of the first water retaining part 410 is provided with a flow guide rib 60, the flow guide rib 60 is arranged at the rear side of the bearing seat 20, the distance between the rear end of each flow guide rib 60 and the tube plate 310 is greater than the distance between the front end of the flow guide rib 60 and the tube plate 310.

[0043] In this embodiment, the lower side surface of the first water retaining part 410 is provided with a flow guide rib 60, the flow guide rib 60 is at the rear side of the bearing seat 20, and the flow guide rib 60 is arranged to be inclined from inside to outside towards the rear side. When the condensate drops to the first water retaining part 410, part of the condensate flows from the outer edge of the first water retaining part 410 to the lower side surface of the first water retaining part 410, and the condensate on the lower side surface of the first water retaining part 410 flows along the flow guide rib 60, the flow guide rib 60 guides the condensate from the outside of the rear end of the lower side surface of the first water retaining part 410 to the inside, and finally makes the condensate flow downward along the outer surface of the tube plate 310. Due to the inclined arrangement of the flow guide rib 60 from inside to outside towards the rear side, the condensate is prevented from flowing forward from the rear end of the lower surface of the first water retaining part 410 to the bearing seat 20, thereby preventing the condensate from entering the bearing seat 20 from the outer end of the bearing seat 20 and corroding the inside of the bearing, and avoiding affecting the service life of the bearing.

[0044] In some embodiments of the utility model, as shown in Figure 4 and Figure 5 As shown, the lower side surface of the first water retaining part 410 is arranged to be inclined relative to the outer surface of the tube plate 310. The outer edge of the lower side surface of the first water retaining part 410 is higher than the inner edge of the lower side surface of the first water retaining part 410 which is connected to the tube plate 310.

[0045] In this embodiment, the inner edge of the lower side surface of the first water retaining part 410 is on the outer surface of the tube plate 310, and the outer edge of the lower side surface of the first water retaining part 410 is higher than the inner edge. When the condensate drops to the first water retaining part 410, part of the condensate flows from the outer edge of the first water retaining part 410 to the lower side surface of the first water retaining part 410, and then the condensate flows from the outer edge to the inner edge of the lower side surface of the first water retaining part 410, and finally flows downward along the outer surface of the tube plate 310. By arranging the outer edge of the lower side surface of the first water retaining part 410 to be higher than the inner edge, the condensate is prevented from directly dripping downward from the outer edge of the lower side surface of the first water retaining part 410, thereby preventing the condensate from entering the bearing seat 20 from the outer end of the bearing seat 20 and corroding the inside of the bearing, and avoiding affecting the service life of the bearing.

[0046] In some other embodiments of this utility model, the lower surface of the first water-blocking part 410 is inclined relative to the outer surface of the tube sheet 310. The outer edge of the lower surface of the first water-blocking part 410 is higher than the lower surface of the first water-blocking part 410 and is connected to the inner edge of the tube sheet 310. Furthermore, a guide rib 60 is provided on the lower surface of the first water-blocking part 410. The guide rib 60 is located on the rear side of the bearing seat 20, and the distance between the rear end of each guide rib 60 and the tube sheet 310 is greater than the distance between the front end of the guide rib 60 and the tube sheet 310.

[0047] In this embodiment, the inner edge of the lower surface of the first water-blocking part 410 is located on the outer surface of the tube sheet 310, and the outer edge of the lower surface of the first water-blocking part 410 is higher than the inner edge. Furthermore, a guide rib 60 is provided on the lower surface of the first water-blocking part 410, located on the rear side of the bearing housing 20, and inclined from the inside out towards the rear. The inclination of the lower surface of the first water-blocking part 410 and the provision of the guide rib 60 further prevent condensate from dripping directly downwards from the outer edge of the lower surface of the first water-blocking part 410, thereby preventing condensate from entering from the outer end of the bearing housing 20 and corroding the interior of the bearing housing 20, thus avoiding affecting the service life of the bearing.

[0048] In some embodiments of this utility model, such as Figure 2 As shown, the first water-blocking part 410 is spaced apart from the bearing seat 20. A water-blocking rib 270 is provided on the upper side of the bearing seat 20. The water-blocking rib 270 is located on the outer side of the tube sheet 310 and is spaced apart from the tube sheet 310.

[0049] In this embodiment, a water-blocking rib 270 is provided on the upper side of the bearing housing 20. The water-blocking rib 270 is located on the outer side of the tube sheet 310 and is spaced apart from the tube sheet 310. When condensate drips onto the first water-blocking part 410, some of the condensate flows along the outer surface of the first water-blocking part 410 to the lower surface, and then flows along the lower surface and the outer surface of the tube sheet 310. At the connection position between the bearing housing 20 and the tube sheet 310, condensate easily flows from the outer surface of the tube sheet 310 to the outer surface above the bearing housing 20 and flows along the outer surface of the bearing housing 20. By providing a water-blocking rib 270 on the upper side of the bearing housing 20, the water-blocking rib 270 prevents condensate from flowing outward on the bearing housing 20. The condensate above the bearing housing 20 flows downward from the outer surface of the bearing housing 20 between the water-blocking rib 270 and the tube sheet 310, preventing condensate from flowing along the outer surface of the bearing housing 20 to the outer end of the bearing housing 20. This prevents condensate from entering the interior of the bearing housing 20 from the end, thus avoiding affecting the service life of the bearing.

[0050] In some embodiments of this utility model, such as Figure 2 , Figure 3 and Figure 6As shown, the outer side of the bearing seat 20 is provided with a first ring 210 and a second ring 220, and the first ring 210 and the second ring 220 define an insertion ring groove 230 therebetween, and the edge of the mounting gap 311 is located in the insertion ring groove 230. The first ring 210 is located at the outer side of the tube plate 310, and the first ring 210 and the water baffle 270 define a water guide groove 260 therebetween.

[0051] In the embodiment, when the edge of the mounting gap 311 is located in the insertion ring groove 230, the first ring 210 is located at the outer side of the tube plate 310, and the second ring 220 is located at the inner side of the tube plate 310. The first ring 210 and the water baffle 270 define the water guide groove 260 therebetween. When the condensate water flows along the outer surface of the tube plate 310, the condensate water above the bearing seat 20 flows down along the outer side surface of the first ring 210 and flows along the water guide groove 260 between the first ring 210 and the water baffle 270. Through the arrangement of the water guide groove 260, after the condensate water above the bearing seat 20 flows down along the outer side surface of the first ring 210, the condensate water flows along the water guide groove 260 between the first ring 210 and the water baffle 270, thereby avoiding the condensate water flowing along the outer surface of the bearing seat 20 to the end portion of the outer side of the bearing seat 20, so as to avoid the condensate water entering the inner portion of the bearing seat 20 from the end portion, thereby avoiding affecting the service life of the bearing.

[0052] Further, when the condensate water on the tube plate 310 flows downward, part of the condensate water may flow downward from the gap between the first ring 210 and the tube plate 310. Due to the arrangement of the insertion ring groove 230, the condensate water flows downward from the gap between the first ring 210 and the tube plate 310 into the insertion ring groove 230, thereby further avoiding the condensate water flowing along the outer surface of the bearing seat 20, so as to avoid the condensate water entering the inner portion of the bearing seat 20 from the end portion, thereby avoiding affecting the service life of the bearing.

After the condensed water drops on the first water retaining portion 410 from the heat exchanger, the condensed water flows along the first water retaining portion 410, and flows forward to the second water retaining portion 420, the second water retaining edge 450 at the outer side of the second water retaining portion 420 prevents the condensed water from dropping downward from the outer edge of the second water retaining portion 420. The third water retaining edge 460 is located at the front side of the first water retaining portion 410, and prevents the condensed water from dropping downward from the front side of the first water retaining portion 410. Through the arrangement of the second water retaining portion 420, the second water retaining edge 450 and the third water retaining edge 460, the condensed water flows from the first water retaining portion 410 to the second water retaining portion 420, the condensed water is prevented from dropping downward from the front side of the first water retaining portion 410 and the outer edge of the second water retaining portion 420, and the condensed water is prevented from dropping into the bearing seat 20, so that the condensed water is prevented from entering the inside of the bearing seat 20 from the end portion, and the service life of the bearing is prevented from being affected.
