[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Please refer to Figures 1 to 5The embodiment of the present invention provides an air conditioner water receiving pan drainage assembly, including: an inner water retaining cover 10 and an outer water retaining cover 20. During installation, the inner water retaining cover 10 is used to cover the drainage hole 31 of the water receiving pan 30, and the bottom of the inner water retaining cover 10 is used to be fixed on the bottom plate 32 of the water receiving pan. Compared with the existing method of fixing the water retaining cover on the flange of the water receiving pan 30, it can ensure that the bottom of the inner water retaining cover 10 and the water receiving pan 30 are in a fit relationship to ensure its water guiding effect, wherein the inner water retaining cover 10 can be fixed on the bottom plate 32 by welding, and a first water diversion hole 11 is provided on one side of the inner water retaining cover 10. The outer water retaining cover 20 is arranged on the outside of the inner water retaining cover 10, and a preset gap is left between the inner water retaining cover 10 and the outer water retaining cover 20. The first side plate of the outer water retaining cover 20 can be used to correspond to the evaporator. No water diversion hole is set on the first side plate. The first side plate is a side plate facing away from the opening of the first water diversion hole 11 on the outer water retaining cover 20. The side wall adjacent to the first side plate and / or the side wall away from the first side plate on the outer water retaining cover 20 is provided with a second water diversion hole 21, that is, the second water diversion hole 21 is away from the evaporator. In the prior art, a water diversion hole is set on the side plate corresponding to the evaporator on the water retaining cover. At this time, a larger space needs to be reserved between the water retaining cover and the evaporator to allow the condensed water generated by the evaporator to pass through. However, the utility model can make the outer water retaining cover 20 closer to the evaporator by setting the second water diversion hole 21 at a position away from the first side plate, thereby reducing the space required for installation. The second water inlet 21 is connected to the first water inlet 11 via a predetermined gap to form a curved water inlet channel. This increases the pressure at the drain hole 31, allowing the condensed water in the water receiving pan 30 to drain smoothly, thereby effectively ensuring the water shield's ability to guide the condensed water. It should be noted that the water receiving pan 30 here refers to the water receiving pan used to receive the condensed water generated by the evaporator.

[0037] In some embodiments, as Figure 3 As shown, the bottom of the inner water retaining cover 10 is provided with a first flange 12, and the first flange 12 is fixed on the base plate 32, wherein the lower surface of the first flange 12 contacts the upper surface of the base plate 32, and the first flange 12 can be fixed to the base plate 32 by welding.

Both sides of the guide plate 22 are spaced apart from the outer water shield 20 and the inner water shield 10. The first water inlet 11 is connected to the second water inlet 21 through the gap between the guide plate 22 and the inner water shield 10, the gap between the guide plate 22 and the first side plate, and the gap between the guide plate 22 and the outer water shield 20. The flow direction of the condensed water is as shown in FIG. Figure 2 As shown by the dotted arrow in the figure, the condensed water can first enter the gap between the guide plate 22 and the outer water retaining cover 20 from the second water inlet hole 21, and then enter the gap between the guide plate 22 and the inner water retaining cover 10 through the gap between the guide plate 22 and the first side plate, and finally enter the inner cavity of the inner water retaining cover 10 through the first water inlet hole 11, that is, the condensed water enters the inner water retaining cover 10 through a tortuous path.

[0040] In some embodiments, as Figure 2 and Figure 4 As shown, the two ends of the outer water shield 20 corresponding to the first side plate are respectively bent to form a guide plate 22, wherein the two sides of the outer water shield 20 are respectively provided with a second water inlet hole 21, that is, condensed water can enter the outer water shield 20 from the second water inlet holes 21 on both sides, and after being guided by the guide plates 22, enter the inner water shield 10 from the first water inlet hole 11. The outer water shield 20 and the inner water shield 10 can both be selected as bilaterally symmetrical structures.
