7 is a blower for circulating cold air. Reference numeral 28 is a gutter installed in the lower part of the cooler, and receives defrost water when the frost attached to the cooler is melted by a defrosting pipe heater or the like. Reference numeral 29 is a drainage conduit for guiding the defrosting water collected in the gutter to an evaporation tray 31 installed in a machine room 30 formed in the lower part of the refrigerator. The drainage conduit 29 forms the freezing compartment 22 and the refrigerating compartment 23. Defrost water is guided from the gutter 28 to the evaporation tray 31 through the foam insulation 34 filled between the box 32 and the outer box 33 forming the outer shell. That is,
One end of the drainage conduit 29 is connected to the gutter 28, and the other end is opened in the machine room 30 so as to face the evaporation tray 31.

に於いても煩わしいと云う問題があった。It cannot be shared even when the size between the gutter 28 and the evaporation tray 31 is slightly changed (in the case of a refrigerator having a different height). For example, a drainage conduit 29 having a length difference of 5 mm to 10 mm must be prepared. There was a problem of not becoming. Therefore, there is a problem that it is troublesome not only in production but also in inventory management at the time of service.

水導管を準備しなくても良いようにしたものである。That is, a defrosting water received by a gutter installed in the lower part of the cooler is introduced into a defrosting water receiving pan installed in a machine room through a drainage conduit embedded in a foam insulation material. At this point, an elastic part whose length can be adjusted is provided in the middle of the drainage pipe so that it is not necessary to prepare several kinds of drainage pipes having different lengths due to the height difference of the refrigerator.

This makes it possible to support refrigerators of different types. That is, by preparing the bellows part of the drainage conduit in a contracted state in advance, a refrigerator having a taller height can be used by extending the bellows part as the height increases.

B shows a straight pipe part. A is a bellows member forming the bellows portion. As shown in FIG. 5, the bellows member A1 moves like a solid line when extended and moves like a broken line when contracted. Then, the straight line P is used as a dead point, and a spring action is performed. As a result, the bellows member A1 remains stretched, or
It keeps the shrunk state. Of course, when the drainage conduit 9 is used for a bent portion, as shown in FIG. 6, the bellows member A1 is fully extended on the side having a large radius of curvature, and contracted when the radius of curvature is small. Even at this time, the above-mentioned state of expansion and contraction is maintained.
