Referring to fig. 8, in an embodiment, the upper cover 21 is provided with a water receiving groove 211 and a water guiding groove 212, the water receiving groove 211 is opened on the upper surface of the upper cover 21, the water receiving portion 213 is arranged on the water receiving groove 211, the water guiding groove 212 is arranged adjacent to and communicated with the water receiving groove 211, a groove surface of the water guiding groove 212 is lower than a groove surface of the water receiving groove 211, and the tail end of the water guiding groove 212 is provided with the water outlet 2121. Specifically, the upper cover 21 is a rectangular cover body as a whole, the upper cover 21 includes an upper surface and four end surfaces located on the peripheral sides, the water receiving groove 211 is formed on the upper surface of the upper cover 21, the water receiving groove 211 is recessed by a certain depth, the water receiving portion 213 is arranged on the water receiving groove 211, the water guide groove 212 is formed beside the water receiving groove 211, the water guide groove 212 is deeper relative to the recessed depth of the water receiving groove 211, that is, the groove surface of the water guide groove 212 is lower than that of the water receiving groove 211, and therefore, a height difference is formed between the water guide groove 212 and the water receiving groove 211, and therefore water on the water receiving groove 211 can fall onto the water guide groove 212. The primary function of the gutter 212 is to direct the flow of water to the location of the drain 2121, since the drain 2121 needs to be aligned with the condenser or with the chassis 233, and therefore the gutter 212 needs to be positioned to direct the condensate. In this embodiment, the groove surface of the water guide groove 212 is inclined toward the water discharge opening 2121, that is, the water discharge opening 2121 is located at the lowest position of the water guide groove 212, so that water falling down from the water receiving groove 211 onto the water guide groove 212 flows to the water discharge opening 2121 and is discharged from the water discharge opening 2121. When the indoor unit 100 is used in combination with the outdoor unit 200, the drain joint 12 is connected to the water receiving portion 213, and the condensed water of the indoor unit 100 flows through the water receiving groove 211 along the flow path of the drain joint 12 and the water receiving portion 213, then falls from the water receiving groove 211 to the water guide groove 212, is guided to the drain opening 2121 by the water guide groove 212, and is discharged through the drain opening 2121, so that the condensed water is drained, and the structure is simple, and a drain pipe is not required.
Referring to fig. 9 and 10, in the present embodiment, the water receiving portion 213 is a water receiving nozzle, and the water receiving nozzle is provided with a drainage notch 2131 penetrating in an axial direction. Specifically, the water receiving nozzle is a hollow cylinder and protrudes from the water receiving tank 211, and the water receiving nozzle is used for being in butt joint with the drainage connector 12, so that the condensed water can flow to the water receiving tank 211 along the wall surface of the water receiving nozzle. Because the water receiving nozzle is a hollow cylinder, part of condensed water can be accumulated in the hollow part of the cylinder to cause water accumulation. Therefore, in order to avoid water accumulation, the wall surface of the water receiving nozzle is provided with the drainage notch 2131, and the drainage notch 2131 penetrates through the whole wall surface along the axial direction of the cylinder, so that the accumulated water in the cylinder can be completely discharged, and the situation of accumulated water is avoided.

The opening 215 is opened at one side of the through-groove 214 in order to facilitate the hose assembly 300 to be wound out of the opening 215. Since the upper cover 21 is concentric with the center of the coil support 24 and the hose assembly 300 is relatively thick and has a certain bending radius, when the hose assembly 300 is wound on the coil support 24, the hose assembly 300 can be more conveniently wound out of the outdoor unit 200 at a position away from the center of the coil support 24, so that the opening 215 is opened at one side of the pipe passing groove 214. Wherein, assuming that the width of the front end surface of the upper cover 21 is L, the diameter of the tube bundle of the hose assembly 300 is D, and the length of the tube passing groove 214 is L1, L > L1>0.5L. The width of the pipe passing groove 214 is W1, and the height of the pipe passing groove 214 is H1, W1> D, and H1> D. The length of the opening 215 is L2, the width of the opening 215 is W2, and the height of the opening 215 is H2, L2> D, W > D, H > D. The distance between the opening part 215 and the circle center of the coil pipe bracket 24 is R, and R is larger than the minimum bending radius of the hose pipe bundle of the hose pipe, and the pipe bundle extends out of the opening part 215 to the external machine. Since the pipe passing groove 214 penetrates the upper surface of the upper cover 21, the hose assembly 300 can be extended upward from the opening 215 to be connected to the top indoor unit 100 when the indoor unit 100 and the outdoor unit 200 are used in combination. The duct groove 214 penetrates the circumferential end surface of the upper cover 21, so that the hose assembly 300 can be extended forward from the opening 215 to be connected to the indoor unit 100 in a separated state of use when the indoor unit 100 and the outdoor unit 200 are separated. In short, the pipe groove 214 and the opening 215 are provided, so that the pipe is not easily broken because the bending radius of the pipe harness is large and the bending stress is small when the hose assembly 300 passes through the opening 215.
