[0030] See also Figures 1 to 3The embodiment of the present invention provides an air conditioner indoor unit 100. The air conditioner indoor unit 100 may be an indoor unit of a split air conditioner. The air conditioner indoor unit 100 can drain condensed water, which is beneficial to the drainage and treatment of condensed water, effectively preventing or reducing water leakage of the air conditioner, thereby improving user experience.

[0031] In an embodiment of the present invention, the air conditioner indoor unit 100 includes an air guide blade 110, an air guide frame 120, an air duct 130 and a water receiving tray, the air guide blade 110 is installed on the air guide frame 120, and the air guide frame 120 is detachably connected to the air duct 130; the air duct 130 is provided with a drainage hole 132, the air guide frame 120 is provided with a drainage hole 121 above the drainage hole 132, the drainage hole 121 is used to drain water to the drainage hole 132, the water receiving tray is provided below the drainage hole 132, and the drainage hole 132 is used to drain water to the water receiving tray.

[0032] It should be noted that when the indoor unit 100 of the air conditioner is working, the air outlet direction is adjusted by the air guide blades 110 on the air guide frame 120. The indoor air and the air outlet of the air conditioner exchange heat near the air outlet of the indoor unit, and condensed water is generated on the air guide blades 110. In the embodiment of the present invention, the condensed water flows downward along the air guide blades 110 to the air guide frame 120 under the action of gravity; the air guide frame 120 is provided with a guide hole 121, and the guide hole 121 is located above the drainage hole 132. The guide hole 121 can drain the condensed water to the drainage hole 132, and the condensed water can enter the water receiving tray through the drainage hole 132; the water in the water receiving tray is then uniformly treated, thereby realizing the treatment of the condensed water on the air guide blades 110.

[0033] That is to say, for the air conditioning indoor unit 100 provided in the embodiment of the present invention, the condensed water on the air guide blade 110 flows to the water receiving tray roughly along the following flow path: air guide blade 110, air guide frame 120, guide hole 121, drainage hole 132, and water receiving tray.

[0034] It should also be pointed out that in the prior art, the water receiving pan is configured to receive the condensed water generated by the evaporator, and then the condensed water on the water receiving pan is processed, such as heating and evaporation, etc. In the present application, the water receiving pan can not only receive the condensed water generated by the condenser, but also receive the condensed water generated by the wind guide blade 110, thereby achieving full utilization of the water receiving pan. Moreover, the condensed water can also be processed uniformly by the water receiving pan, making the processing of the condensed water more convenient and simple.

[0035] At the same time, during the flow of condensed water, the condensed water flows through the above-mentioned air guide blades 110, air guide frame 120, guide holes 121, drainage holes 132 and water receiving tray one by one under the action of gravity without providing external power, that is, the drainage of condensed water can be achieved without increasing additional power consumption.

[0036] In addition, in the embodiment of the present invention, the air guide frame 120 is detachably connected to the air duct 130, and the air guide frame 120 can be easily removed from the air duct 130, which is convenient for cleaning and repairing the air duct 130. That is, the embodiment of the present invention can also facilitate the disassembly and assembly of the air conditioner indoor unit 100, thereby facilitating the disassembly, cleaning and repair of the air conditioner indoor unit 100.

[0037] See also Figure 4 In an optional embodiment, a water collecting tank 133 is further provided on the air duct 130, and the end of the air guide blade 110 can be accommodated in the water collecting tank 133. The water collecting tank 133 and the drainage hole 132 are both arranged below the air duct 130, and the water collecting tank 133 can accommodate the end of the air guide blade 110, so as to guide the condensed water on the air guide blade 110 into the water collecting tank 133.

[0038] It should be noted that the air guide frame 120 is equipped with an air guide blade 110, and condensation water may also be generated on the air guide frame 120. The condensation water flows downward along the air guide blade 110, and the end of the air guide blade 110 is accommodated in the water collecting tank 133. The condensation water enters the water collecting tank 133 at the end of the air guide blade 110. The water collecting tank 133 is connected to the drainage hole 132, so that the condensation water in the water collecting tank 133 can be drained to the drainage hole 132, and then drained to the water receiving tray through the drainage hole 132.

[0039] In an embodiment of the present invention, the air duct 130 may also be provided with a drainage groove 131. Optionally, the drainage groove 131 connects the drainage hole 132 and the water collecting groove 133. In this case, the drainage hole 132 is away from the water collecting groove 133, and the drainage hole 132 and the water collecting groove 133 are connected through the drainage groove 131. Alternatively, the drainage hole 132 is provided between the water collecting groove 133 and the drainage groove 131, that is, the drainage groove 131 and the water collecting groove 133 are both connected to the drainage hole 132. At this time, the guide hole 121 provided on the air guide frame 120 can be approximately located above the drainage groove 131, that is, the condensed water dripping from the guide hole 121 can be drained through the drainage groove 131.

[0040] In the embodiment of the present invention, the drainage hole 132 is far away from the water collecting tank 133 and is approximately located behind the air outlet of the air-conditioning indoor unit 100 .

[0041] In an optional embodiment, the air duct 130 has an air outlet of the air conditioner indoor unit 100 , the water collecting tank 133 is close to the outside of the air outlet, and the drainage groove 131 extends from the water collecting tank 133 toward the inside of the air outlet to the drainage hole 132 .

[0042] Optionally, the drainage groove 131 and the water collecting groove 133 are recessed relative to one side of the air duct 130, and protrude from the other opposite side. The drainage groove 131 and the water collecting groove 133 can be set by an integrated molding process, and the drainage groove 131 and the water collecting groove 133 have a certain depth, and the depth can be greater than the thickness of the air duct 130. At this time, the other side of the drainage groove 131 and the water collecting groove 133 can be protruded relative to the surface of the air duct 130. Since the water receiving tray is usually set to a cavity shape, it is sufficient to accommodate the protruding parts of the drainage groove 131 and the water collecting groove 133. In other words, without additionally increasing the thickness of the air duct 130, a drainage groove 131 and a water collecting groove 133 with a certain depth that protrude relative to the air duct 130 can be set without affecting the assembly of the air duct 130 and the water receiving tray and other components.

[0043] Optionally, the width of the water collecting groove 133 is greater than the width of the drainage groove 131. Further, the width of the drainage groove 131 at the end arm of the wind guide blade 110 is slightly larger, and when the air duct 130 and the wind guide frame 120 are assembled, the end of the wind guide blade 110 will not enter the drainage groove 131, but only cooperate with the water collecting groove 133, which can facilitate the assembly of the wind guide frame 120.

[0044] It should be understood that the width of the water collecting groove 133 should be at least equal to the diameter of the end of the wind guide blade 110, so that the end of the wind guide blade 110 can be assembled into the water collecting groove 133. Optionally, the width of the water collecting groove 133 is slightly larger than the diameter of the end of the wind guide blade 110.

[0045] See also Figure 5 In an optional embodiment, the drainage groove 131 includes a first end 1311 and a second end 1312, the air duct 130 surrounds the air outlet of the air conditioner indoor unit 100, the first end 1311 is close to the outside of the air outlet, the drainage hole 132 is close to the second end 1312, and the bottom wall of the drainage groove 131 is inclined from the first end 1311 along the second end 1312 to drain water from the first end 1311 to the second end 1312 and flow into the drainage hole 132.

[0046] That is, in the flow direction of the condensed water, the drainage groove 131 is inclined so as to drain the condensed water to the drainage hole 132. Similarly, in the embodiment of the present invention, the drainage hole 121 on the air guide frame 120 is located at the rear of the air guide frame 120, and the bottom of the air guide frame 120 is inclined toward the drainage hole 121, that is, the drainage slope 123, so as to drain the condensed water on the air guide blade 110 to the drainage hole 121 through the air guide frame 120.

[0047] At the same time, in an optional embodiment, the side wall of at least one of the drainage groove 131, the drainage hole 132, the water collecting groove 133, and the guide hole 121 is inclined so that the diameter of the upper part is larger than the diameter of the lower part, so that the condensed water can be quickly gathered, thereby receiving more condensed water.

[0048] In an optional embodiment, the air duct 130 forms an air outlet of the air conditioner indoor unit 100, a first clamping portion is provided on at least one side of the air outlet, and the air guide frame 120 is provided with a second clamping portion detachably connected to the first clamping portion. The first clamping portion and the second clamping portion can realize a detachable connection between the air guide frame 120 and the air duct 130, and the clamping structure is simple and easy to operate, which is conducive to improving the disassembly and assembly efficiency of the air guide frame 120 and the air duct 130.

[0049] Further, a positioning pin is provided at the top and / or bottom of the air guide frame 120, and a limiting groove cooperating with the positioning pin is provided at the air outlet. Optionally, a positioning pin is provided at the top of the air guide frame 120, and correspondingly, a limiting groove cooperating with the positioning pin is provided at the top of the air outlet.

[0050] When the air guide frame 120 is assembled, the positioning pins at the top and / or bottom of the air guide frame 120 can be matched with the limiting grooves on the air duct 130, and then the first clamping portion and the second clamping portion are clamped, so that the air guide frame 120 is assembled to the air duct 130. When the air guide frame 120 is disassembled, the first clamping portion and the second clamping portion can be disengaged first, and then the positioning structures at the bottom and the top can be removed, so that the air guide frame 120 can be disassembled from the air duct 130.

[0051] An embodiment of the present invention provides an air conditioner, comprising an outdoor unit and an air conditioner indoor unit 100 as in any one of the above embodiments. The air conditioner has similar beneficial effects as the above air conditioner indoor unit 100, that is, it can drain the condensed water generated by the air guide blades 110 to the water receiving tray, thereby improving the user experience.

[0052] Please refer to Figures 1 to 6, the air conditioner indoor unit 100 and the air conditioner provided in the embodiment of the present invention: the air conditioner indoor unit 100 is in the air outlet where the indoor gas undergoes heat exchange, and condensed water is formed on the air guide blade 110.
