Specifically, the drainage pipe 100 includes a water receiving tank 110 disposed at the top end, and a pipe 120 communicated with the water receiving tank 110, and the pipe 120 further includes a water outlet 121, specifically, in this embodiment, a water leaking opening 111 is formed in a concave inner surface of the water receiving tank 110, the water outlet 121 is communicated with the water leaking opening 111 through the pipe 120, and water received in the water receiving tank 110 can be collected into the water leaking opening 111, flow into the pipe 120, and then flow out from the water outlet 121.

Further, referring to fig. 2, the valve body 200 may be assembled into the pipe 120 from the water outlet 121, the valve body 200 includes a base 210 and a boss 220 protruding upward from the base 210, and the boss 220 is formed with a plug 221, obviously, the assembly of the valve body 200 into the pipe 120 means that the plug 221 is assembled into the pipe 120. In this embodiment, the plug 221 is disposed at one end of the protruding pillar 220 away from the base 210, and the outer diameter of the plug 221 is adapted to the inner diameter of the pipe 120, when the valve body 200 is assembled into the pipe 120, the plug 221 is also inserted into the pipe 120 immediately and attached to the inner wall of the pipe 120, meanwhile, in order to allow water in the pipe 120 to flow out, the edge of the plug 221 is recessed inward along the radial direction to form at least one groove, and a drainage channel 222 is formed between the edge and the inner wall of the pipe 120, when the water in the pipe 120 flows to the plug 221 position, the water can flow out from the drainage channel 222, in this embodiment, four grooves are symmetrically disposed, that is, four symmetrical drainage channels 222 are formed.

Further, in order to prevent water from accumulating at the plug 221 during the drainage process, a guide section 223 is disposed at one end of the plug 221 away from the base 210, and the diameter of the guide section 223 gradually decreases from one end thereof close to the base 210 to the other end thereof away from the base 210. Specifically, in this embodiment, the guide segment 223 is formed in a truncated cone shape, and the side surface thereof is an inclined surface, so that when water is discharged into the duct 120, the water can flow into the drainage channel 222 along the side surface of the guide segment 223 and then flow out of the duct 120.

Meanwhile, the convex column 220 further includes a column 224 connecting the plug 221 and the base 210, and an outer diameter of the column 224 is smaller than an inner diameter of the pipe 120, so that water in the pipe 120 can flow from the drainage channel 222 to the base 210.

Further, the inner surface of the base 210 protrudes upward to form a supporting portion 211, when the valve body 200 is assembled into the pipe 120, the water outlet 121 can support against the supporting portion 211, so that the water outlet 121 and the inner surface of the base 210 are spaced from each other and form a gap, specifically, in this embodiment, the supporting portion 211 is a convex rib structure, and the supporting portion 211 is arranged to make the water outlet 121 and the inner surface of the base 210 spaced from each other and not attached to each other, so that the water in the pipe 120 can directly flow into the base 210 after being discharged.

Meanwhile, the shape of the base 210 is adapted to the shape of the water outlet 121, the periphery of the base 210 is upwardly surrounded by the convex edge 212, when the valve body 200 is assembled into the pipeline 120, the convex edge 212 can surround the water outlet 121 and fix the base 210 and the pipeline 120, so that the valve body 200 and the pipeline 120 are fixed; meanwhile, a plurality of gaps 213 are concavely formed on the convex edge 212, and water can flow to the base 210 along the drainage channel 222 and flow out through the gaps 213.

Further, at least one positioning block 122 is formed by protruding one side of the pipe 120 close to the water outlet 121, and when the valve body 200 is assembled into the pipe 120, the positioning block 122 can be inserted into and clamped with the gap 213 to limit the valve body 200 from rotating relative to the pipe 120, so that the whole drain assembly is more stable, in this embodiment, one positioning block 122 is provided.

In this embodiment, the pipe 120 and the water receiving tank 110 are inclined at an included angle, in order to make the plug 221 and the inner wall of the pipe 120 more closely fit, the convex column 220 is also inclined at the same included angle with the base 210, and after the valve body 200 is assembled into the pipe 120, the water receiving tank 110, the water outlet 121 and the base 210 are all parallel to each other. That is, when the water receiving tank 110 is placed in the horizontal direction, the pipe 120 is inclined with respect to the water receiving tank 110, so that the flow of water during drainage can be buffered to some extent, and noise generated in the pipe 120 during drainage can be reduced to some extent.

Referring to fig. 3, the whole drainage process is described with reference to the sectional view of the drainage assembly, when water is received in the water receiving tank 110, the water collects in the concave portion of the inner wall of the water receiving tank 110, i.e., the drainage opening 111, then enters the pipe 120 to flow to the plug 221, and flows into the drainage channel 222 through the guide section 223 and collects in the base 210, and because the drainage opening 121 abuts against the abutting portion 211 to form a gap, the water in the base 210 flows out from the gap through the gap 213 on the flange 212.

Meanwhile, the invention also provides a refrigerator, which comprises: the water collecting plate is arranged in the press bin and used for collecting water; the refrigerator also comprises the drainage assembly, wherein the drainage assembly is partially arranged in the press bin and arranged above the water receiving tray, so that condensed water flows through the drainage assembly and is discharged into the water receiving tray.
