In the process of downward flowing of the condensed water in the heat exchanger 20, one part of the condensed water directly drops into the water receiving disc 32 along the heat exchanger 20, the other part of the condensed water downwards flows to the upper part of the flow guiding frame 31 along the heat exchanger 20, the flow guiding frame 31 divides the water flow, and the water flow flows into the water receiving disc 32 along the two sides of the flow guiding frame 31.
Further, the orthographic projection of the diversion frame 31 between two adjacent water receiving discs 32 in the horizontal plane covers the orthographic projection of the gap between the two water receiving discs 32 in the horizontal plane, that is, both ends of the diversion frame 31 extend above the adjacent water receiving discs 32, for example, the front side of the diversion frame 31 extends above the water receiving groove at the front side of the diversion frame 31, and the rear side of the diversion frame 31 extends above the water receiving groove at the rear side of the diversion frame 31. The water flow flowing out of the guide frames 31 can fall into the water receiving tank, and the condensed water flowing out of the part of the heat exchanger 20 between the adjacent guide frames 31 can smoothly flow into the water receiving tank, so that the water receiving efficiency of the water receiving assembly 30 is improved, and the indoor environment is prevented from being polluted by water flow leakage.

The guide frame 31 with the structure is simple in structure and easy to manufacture, on one hand, the plate-shaped guide beam 311 can guide water flow to enter the water receiving tank to prevent the water flow from vertically flowing downwards and falling into the room, and on the other hand, the support ribs 312 perpendicular to the guide beam 311 can improve the bearing capacity of the guide frame 31 to prevent the guide beam 311 from bearing too much damage.
As shown in fig. 1, the supporting ribs 312 are located at the center of the guiding beam 311 in the width direction of the guiding beam 311, for example, the cross section of the guiding frame 31 may be formed in a T shape, the spaces on both sides of the supporting ribs 312 are the same, and the air flow uniformly enters the air conditioning indoor unit 100 through both sides of the supporting ribs 312, so that the air conditioning indoor unit 100 can return air uniformly, and the stability of the return air flow is improved.

Further, as shown in fig. 2, the carrying and ventilating frames 31 and 31 are alternately arranged along the width direction of the heat exchanger 20, that is, the frames 31 include both the carrying and ventilating frames 31, so that the carrying capacity of the whole structure of the frames 31 can be improved by using the carrying and ventilating frames 31, and the damage of the supporting structure can be prevented.
As shown in fig. 3 to 5, in the present embodiment, the top of the guide beam 311 is formed with a gradual change portion 3111, and the cross-sectional area of the gradual change portion 3111 gradually decreases from bottom to top, wherein the gradual change portion 3111 may be formed as a support portion protruding upward along the top of the guide beam 311, and the contact area of the support portion with the heat exchanger 20 is small.
Specifically, the guide beam 311 is divided into an upper portion and a lower portion in a vertical direction, the lower portion may be formed in a rectangular parallelepiped structure, the upper portion is formed as a tapered portion 3111 provided on the rectangular parallelepiped, a cross-sectional area of the tapered portion 3111 parallel to a lower surface of the heat exchanger 20 is gradually increased in a direction from top to bottom, and for example, a cross-section of the tapered portion 3111 may be triangular, trapezoidal, or arc-shaped.

The guide frame 31 with the structure has higher structural strength, improves the bearing capacity of the guide frame 31, can guide condensed water to flow out by limiting the supporting water receiving tank in the guide frame 31, prevents water flow from leaking from the guide frame 31 to the water receiving disc 32, and improves the water receiving effect of the water receiving assembly 30.
According to an alternative embodiment of the present invention, the water pan 32 includes a bottom wall 321 and two side walls 322, the side walls 322 being connected to the outer periphery of the bottom wall 321, the side walls 322 and the bottom wall 321 cooperatively defining a water receiving channel. The bottom wall 321 of the water tray 32 may extend in a horizontal direction, and the side wall 322 of the water tray 32 extends upward in a direction away from the bottom wall 321 in a bottom-to-top direction, that is, the open area of the water tray 32 is larger than the area of the bottom wall 321. For example, referring to fig. 2 and 6, the cross-sectional shape of the water receiving tray 32 is formed in a trapezoid shape. Therefore, the water receiving space of the water receiving disc 32 can be increased, the water receiving capacity of the water receiving disc 32 is improved, and water in the water receiving disc 32 is prevented from overflowing.
As shown in fig. 7, according to an embodiment of the present invention, one of the two adjacent water-receiving trays 32 is connected to the guide frame 31 between the two water-receiving trays 32, and the other of the two adjacent water-receiving trays 32 is spaced apart from the guide frame 31 between the two water-receiving trays 32.
That is, one water receiving tray 32 is connected to one guide frame 31 to form a combined structure, which not only can support the heat exchanger 20, but also can receive or guide condensed water flowing down in the heat exchanger 20, and a plurality of combined structures arranged at intervals form the water receiving assembly 30.
The support frame is connected with the water pan 32, so that the matching stability of the diversion frame 31 and the water pan 32 can be improved, the supporting strength of the diversion frame 31 can be improved, leakage can be prevented when water flow on the diversion frame 31 enters the water pan 32, and the structural design of the water receiving assembly 30 can be simplified.
As shown in fig. 7, according to an embodiment of the present invention, the guide frame 31 is formed in a plate shape extending in a width direction of the heat exchanger 20, and the water receiving tray 32 includes: the water receiving plate 323 and the water blocking rib 324, one side of the water receiving plate 323 is connected with the guide frame 31, the other side of the water receiving plate 323 is inclined downwards along the width direction of the heat exchanger 20, and condensed water flowing out of the heat exchanger 20 flows downwards along the plate-shaped guide frame 31 and the water receiving plate 323.

The lower surface of the water receiving plate 323 and the upper surface of the water receiving plate 323 of the adjacent water receiving plate 32 define a return air channel, one end of the flow guide frame 31 far away from the water receiving plate 323 is arranged at intervals from the connected water receiving plate 32, the return air channel is communicated with the inner cavity of the air conditioning indoor unit 100 through a gap between the flow guide frame 31 and the water receiving plate 32, and return air flows into the heat exchanger 20 along the return air channel.
The guide frame 31 and the water receiving disc 32 with the above structure not only can support the heat exchanger 20, but also can guide condensed water in the heat exchanger 20 to flow out, and the return air channel guides return air flow, so that the resistance of the return air flow can be reduced, and the return air efficiency of the air conditioner indoor unit 100 is improved.
As shown in fig. 7, according to an embodiment of the present invention, the water tray 32 further includes: the overflow preventing ribs 325, the overflow preventing ribs 325 are provided on the water receiving plate 323 and between the water blocking ribs 324 and the guide frame 31. The overflow preventing ribs 325 cooperate with the water receiving plate 323 to define overflow preventing grooves, which are located above the water receiving tank due to the inclined arrangement of the water receiving plate 323.
When the water in the overflow preventing groove overflows, the overflowed water flows to the water receiving groove. For example, when the indoor unit 100 is operated, condensed water generated at the heat exchanging part of the heat exchanger 20 may first fall into the overflow preventing tank, and when the overflow preventing tank is filled with the condensed water, the overflowed condensed water may flow to the water receiving tank. When the condensed water in the overflow preventing groove is not discharged from the water outlet, the condensed water fills the overflow preventing groove and flows to the water receiving groove. Thus, the water flow in the water receiving tank can be prevented from overflowing due to the fact that the dropping speed of the condensed water is larger than the draining speed of the water receiving tank.
In this embodiment, the included angle between the heat exchanger 20 and the horizontal plane is less than 30 degrees, that is, the heat exchanger 20 is disposed in a substantially horizontal direction. On the one hand, the space dedicated for the heat exchanger 20 in the vertical direction can be reduced, and thus the volume of the air conditioning indoor unit 100 can be reduced, and on the other hand, the width of the heat exchanger 20 can be reduced, and the production cost can be reduced.
According to one embodiment of the present invention, the water receiving assembly 30 is connected to the housing 10 and disposed in the return air inlet 11, and the water receiving assembly 30 is formed as a return air grill of the return air inlet 11.
