Specifically, the panel assembly 500 has at least one air outlet. The switch door mounting plate 600 is connected to the panel assembly 500, and the switch door mounting plate 600 and the panel assembly 500 define a receiving chamber together. The switch door and the driving assembly are installed on the switch door installation plate 600, at least one switch door is located in the accommodating cavity, and the driving assembly is in transmission connection with the switch door to drive the switch door to open and close the air outlet.
Wherein, the inner wall of the accommodating cavity is provided with a water collecting tank 601, and the water collecting tank 601 is provided with a water outlet 602. A water guide groove 603 is provided below the water collection groove 601 and above the water receiving groove 300, one end of the water guide groove 603 communicates with the water outlet 602, and the other end of the water guide groove 603 communicates with the water receiving groove 300.

Further, as shown in fig. 12, the middle portion of the water collecting tank 601 protrudes upward with respect to both ends, that is, the drain port 602 is provided at a lower position of the water collecting tank 601, so that condensed water in the middle portion of the water collecting tank 601 easily flows toward both right and left ends, and condensed water in the water collecting tank 601 easily drains from the drain port 602.
In some embodiments of the present invention, as shown in fig. 11, at least one water blocking rib 604 is disposed in the water guiding groove 603, the water blocking rib 604 extends obliquely from top to bottom, and the horizontal projection of the water draining opening 602 is at least partially located in the horizontal projection of the water blocking rib 604. In this way, the water blocking rib 604 can prevent water discharged from the water outlet 602 from directly dripping into the water pan 31, and splash is formed.
For example, the water retaining ribs 604 are multiple, the multiple water retaining ribs 604 are respectively arranged on the inner walls of the left side and the right side of the water guiding groove 603, the multiple water retaining ribs 604 are staggered along the up-down direction, and the free end of each water retaining rib 604 faces obliquely downwards and is spaced from the inner wall of the water guiding groove 603, so that the falling condensed water can be better guided to flow gently, and the splashing preventing effect is better.
According to some embodiments of the present invention, as shown in fig. 10, the air outlets are plural and include 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. The switch door is a plurality of and includes first switch door 710 and second switch door 720, and first switch door 710 is located the accommodation chamber, and first switch door 710 is along upper and lower direction slidable in order to open and close first air outlet 501, and second switch door 720 is along fore-and-aft direction slidable in order to open and close second air outlet 502. Therefore, the air outlet quantity can be increased, the air outlet quantity change range is larger, the air outlet direction is easy to change, the air outlet comfort is better, and the appearance is good.
Alternatively, as shown in fig. 11, a water collection tank 601 is provided at the bottom wall of the accommodating 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 chamber, and the water collection tank 601 is disposed adjacent to the lower side of the first air outlet 501, so that condensed water in the accommodating chamber communicating with the first air outlet 501 can be discharged.
In some embodiments of the present invention, as shown in fig. 11, the switch door 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 above the second mounting bracket 620, the first mounting bracket 610 and the panel member 10 define an accommodating cavity, and the first switch door 710 is slidably mounted to the first mounting bracket 610 and the second switch door 720 is slidably mounted to the second bracket. Thus, the assembly is convenient.
In one embodiment of the present invention, as shown in fig. 1, the fan assembly 200 includes an upper fan 210 and a lower fan 220, where the upper fan 210 corresponds to a first air outlet 501 and the lower fan 220 corresponds to a second air outlet 502. The upper fan 210 is a counter-rotating fan, and the counter-rotating fan comprises a first wind wheel and a second wind wheel.
Because the first wind wheel and the second wind wheel are contra-rotating fans, namely the inclination directions of the blades of the first wind wheel are opposite to the inclination directions of the blades of the second wind wheel, the first wind wheel and the second wind wheel are guide vanes mutually in the air flowing direction, the tangential rotating speed of air flow (namely dynamic pressure is converted into static pressure) is reduced (under the condition that the first wind wheel and the second wind wheel are at different rotating speeds) or eliminated (under the condition that the first wind wheel and the second wind wheel are at the same rotating speed), the acting efficiency of the contra-rotating fans on the air is improved, and the air flows passing through the two wind wheels flow towards the direction of the air outlet, so that the effect of long-distance air supply is realized.
It should be noted that, compared with a single cross flow fan, an axial flow fan or an oblique flow fan, the first wind wheel and the second wind wheel in the counter-rotating fan can realize the air supply of a longer distance regardless of the reverse rotation at different speeds or the reverse rotation at the same speed.
Secondly, the first wind wheel and the second wind wheel can expand the cold air conveying range under the condition of different rotating speeds. Because when one wind wheel rotates at a higher rotating speed and the other wind wheel rotates at a lower rotating speed, the wind wheel with the higher rotating speed plays a leading role, and the blade air outlet angle design based on the single-stage axial flow or diagonal flow fan deviates from the direction of the rotating shaft, the axial flow wind wheel or diagonal flow wind wheel has a wind dispersing effect, so that the angle range of cold air flowing out from the air outlet is larger, and wide-angle air supply is realized.
In addition, based on the wind dispersing effect of the axial flow wind wheel or the diagonal flow wind wheel, the rotating speeds of the first wind wheel and the second wind wheel can be adjusted according to the requirement, so that the first wind wheel and the second wind wheel rotate in a differential speed mode, soft wind sense or wind sense-free air supply is realized, and bad experience caused by direct blowing of cold air after the cold air flows out from the air outlet to users is avoided.
Therefore, the air conditioning indoor unit 1 of the present embodiment can realize soft air feeling or air supply without air feeling without using an air deflector with micro holes, and the air volume loss is small.
In order to realize wide-angle air supply and air supply without wind sense, the motor corresponding to one wind wheel does not work, and the other wind wheel still supplies air towards one side of the air outlet.
