Fig. 3 is a schematic structural exploded view of the inner container and the drain pipe of the refrigerator according to an embodiment of the present invention, and fig. 4 is a schematic structural view of the first drain pipe and the second drain pipe according to an embodiment of the present invention. In some embodiments, the refrigerator 1 includes a first inner container 11 and a second inner container 12 that are independent from each other, and a first drain 113 and a second drain 123 are respectively opened at the bottom of the first inner container 11 and the bottom of the second inner container 12. The first and second drain pipes 41 and 42 communicate with the first and second drain ports 113 and 123, respectively, to drain condensed water in the first and second liners 11 and 12, respectively.

Further, the connection portion of the first drain pipe 41 and the connection portion of the second drain pipe 42 are respectively fitted to a part of the inner container wall of the first inner container 11 and a part of the inner container wall of the second inner container 12. That is, the inner wall of the first inner container 11 is configured to fit to the connection portion of the first drain pipe 41, and the inner wall of the second inner container 12 is configured to fit to the connection portion of the second drain pipe 42. Therefore, when a certain water drainage pipe is assembled to the inner container which is not corresponding to the water drainage pipe, the connecting part of the water drainage pipe cannot be matched with the inner container wall of the inner container at all, and the fool-proof effect is effectively achieved.

In one embodiment, the connection portion of the first drain pipe 41 includes a plurality of first seal alignment plates 411 attached to the outer side of the inner wall of the first inner container 11, and the connection portion of the second drain pipe 42 includes a plurality of second seal alignment plates 421 attached to the outer side of the inner wall of the second inner container 12. From this, can increase the fitting surface area between drain pipe and the inner bag through the laminating effect between the inner bag wall around sealed locating plate and the outlet, strengthen the sealing performance between drain pipe and the inner bag, avoid the comdenstion water seepage.

Further, the number of the first and second seal positioning plates 411 and 421 is different. Alternatively, the at least one first seal positioning plate 411 and the at least one second seal positioning plate 421 have different shapes. That is to say, can set up the connecting portion of two drain pipes to different from aspects such as quantity, shape of sealed locating plate to the realization distinguishes the purpose of two drain pipes, and the structure is very simple, and realizes very easily.

In some embodiments, the plurality of first seal positioning plates 411 are disposed in number and/or shape to be respectively attached to the bottom wall of the first inner container 11 around the first drain opening 113. The number and/or shape of the second sealing and positioning plate 421 are/is set to be respectively attached to the bottom wall of the second inner container 12 around the second drain opening 123 and one side wall 125 of the second inner container 12. Thereby, the first drain pipe 41 and the second drain pipe 42 can be simply distinguished from each other in the number and/or shape of the first and second seal-positioning plates 411 and 421, which is advantageous for improving the assembly efficiency of the drain pipes.

Further, the first and second drain pipes 41 and 42 have first and second water flow inlets 412 and 422, respectively, for supplying water to flow therein.

Thus, the structure and shape of the four second sealing and positioning plates 421 of the second water discharge pipe 42 can be kept consistent with the four first sealing and positioning plates 411 of the first water discharge pipe 41, and the other second sealing and positioning plate 421 of the second water discharge pipe 42 extending upwards in a bending way forms a fool-proof structure capable of distinguishing the second water discharge pipe 42 from the first water discharge pipe 41.

It can be understood that, since all the first seal positioning plates 411 of the first drain pipe 41 are attached to the bottom wall of the first inner container 11, the first drain port 412 may be opened at a middle position of the bottom wall of the first inner container 11. And the second sealing and positioning plate 421 of the second water discharging pipe 42 is attached to one of the side walls 125 of the second inner container 12 in addition to the bottom wall of the second inner container 12, therefore, the second water discharging port 422 is preferably opened at a position adjacent to the side wall 125 of the bottom wall of the inner container 12, so as to avoid the excessive volume of the connecting part of the second water discharging pipe 42 and increase the assembly burden.

The utility model discloses a grafting structure includes two sets of cooperation mechanisms, and one set is cylindrical positioning element 4253 and first recess 4254's location fit, and another set is bar location muscle 4255 and second recess 4256's location fit. The cylindrical positioning element 4253 is large in size, and the strip-shaped positioning rib 4255 is small in width, that is, the fit between the cylindrical positioning element 4253 and the first groove 4254 is equivalent to roughly pre-positioning the connecting pipe body 4252, and the fit between the strip-shaped positioning rib 4255 and the second groove 4256 is equivalent to finely positioning after the pre-positioning. Through the matching of pre-positioning and fine positioning, the assembling efficiency and the assembling effect of the connecting tube 4252 can be effectively improved.
