In some specific embodiments of the present disclosure, as shown in FIG. 11, at least one water retaining rib 604 is provided in the water guiding groove 603. The water retaining rib 604 extends obliquely from top to bottom, and the horizontal projection of the drain 602 is at least partially located on the retaining wall. Within the horizontal projection of the water rib 604. In this way, the water retaining ribs 604 can prevent the water discharged from the drain port 602 from directly dripping into the water receiving tray 31 and forming water splashes.

For example, there are multiple water-retaining ribs 604, and the multiple water-retaining ribs 604 are respectively provided on the inner walls of the left and right sides of the water guiding groove 603, and the multiple water-retaining ribs 604 are staggered in the up and down direction. The end faces obliquely downward and is spaced apart from the inner wall of the water guiding groove 603, so that the falling condensate can be better guided to flow gently, and the splash prevention effect is better.

According to some embodiments of the present disclosure, as shown in FIG. 10, there are multiple air outlets including a first air outlet 501 and a second air outlet 502, and the first air outlet 501 is located above the second air outlet 502. There are multiple opening and closing doors, including a first opening and closing door 710 and a second opening and closing door 720. The first opening and closing door 710 is located in the accommodating cavity. The first opening and closing door 710 is slidable in the up and down direction to open and close the first air outlet 501. The second opening and closing door 720 is slidable in the front-rear direction to open and close the second air outlet 502. In this way, the air output can be increased, the range of the air volume change is larger, the direction of the air output is also easy to change, the air output comfort is better, and the appearance is good.

Optionally, as shown in FIG. 11, the water collection tank 601 is provided on the bottom wall of the containing cavity, and the water collection tank 601 is located between the first air outlet 501 and the second air outlet 502. For example, the bottom wall of the water collection tank 601 forms the bottom wall of the accommodating cavity, and the water collection tank 601 is arranged adjacent to the first air outlet 501 so as to be able to drain the condensed water in the accommodating cavity communicating with the first air outlet 501.

In some embodiments of the present disclosure, as shown in FIG. 11, the door opening and closing mounting plate 600 includes a first mounting bracket 610 and a second mounting bracket 620. The first mounting bracket 610 is connected to the second mounting bracket 620 and is located in the second mounting bracket. Above the bracket 620, the first mounting bracket 610 and the panel member 10 define an accommodating cavity, the first opening and closing door 710 is slidably mounted on the first mounting bracket 610, and the second opening and closing door 720 is slidably mounted on the second bracket. In this way, it is easy to assemble.

In a specific embodiment of the present disclosure, as shown in FIG. 1, the fan assembly 200 includes an upper fan 210 and a lower fan 220. The upper fan 210 corresponds to the position of the first air outlet 501, and the lower fan 220 and the second air outlet 502 are in positions correspond. The upper fan 210 is a counter-rotating fan, and the counter-rotating fan includes a first wind wheel and a second wind wheel.

Since the first wind wheel and the second wind wheel are counter-rotating fans, that is, the inclination direction of the blades of the first wind wheel is opposite to the inclination direction of the blades of the second wind wheel. The directions are mutually guide vanes, reducing (when the first wind wheel and the second wind wheel are at different speeds) or eliminating (when the first wind wheel and the second wind wheel are at the same speed), the airflow tangential direction is reduced The rotation speed (that is, the conversion from dynamic pressure to static pressure) improves the work efficiency of the counter-rotating fan on the air, and the airflow passing through the two wind wheels flows in the direction of the air outlet, thereby achieving the effect of long-distance air supply.

It should be noted that, compared to a single cross flow fan, axial flow fan or diagonal flow fan, the first and second wind wheels in the counter-cyclone fan rotate in opposite directions at different speeds or at the same speed. Both rotating and counter-rotating fans can achieve longer distance air supply.

Secondly, when the rotation speed of the first wind wheel and the second wind wheel are different, the cold air delivery range can be expanded. Because when one wind wheel rotates at a higher speed and the other wind wheel rotates at a lower speed, the higher speed wind wheel plays a leading role. Based on the single-stage axial flow or diagonal flow fan, the blade air outlet angle design deviates The direction of the rotation axis makes the axial flow wind wheel or the diagonal flow wind wheel have the effect of dispersing wind. Therefore, the angle range of the cold air flowing out from the air outlet is relatively large, thereby realizing wide-angle air supply.

In addition, based on the fact that the axial flow wind wheel or the diagonal flow wind wheel itself has the effect of dispersing the wind, the speed of the first wind wheel and the second wind wheel can be adjusted according to the needs to make them rotate at a differential speed, thereby achieving a soft wind or no wind feeling The air supply prevents the cold air from blowing directly to the user after flowing out of the air outlet, thereby causing a bad experience to the user.

Therefore, the air-conditioning indoor unit 1 of this embodiment does not need to use an air guide plate with micro-holes to achieve soft or no-wind-sensing air supply, with little air volume loss.

It should be noted that, in order to achieve wide-angle air supply and windless air supply, the motor corresponding to one of the wind wheels may not work, and the other wind wheel still sends air in a positive direction toward the air outlet side. In addition, in order to achieve wide-angle air supply and windless air supply, it is also possible to make one of the wind wheels blow the air in the reverse direction while the other wind wheel still blows the air forward. Among them, "forward air supply" means that the airflow blows out from the air outlet under the action of the wind wheel, and "reverse air supply" means that the airflow blows inward.

As shown in FIG. 8, the panel assembly 500 may include an upper panel 510 and a lower panel 520. The upper panel 510 is connected to the lower panel 520 and is located above the lower panel 520. The upper panel 510 is provided with a first air outlet 501 and a second air outlet 502, and the first air outlet 501 is located above the second air outlet 502.

As shown in FIG. 11, the first mounting bracket 610 is connected to the second mounting bracket 620 and is located above the second mounting bracket 620. A containing cavity is defined between the first mounting bracket 610 and the upper panel 510.
