The insertion projection 5 of the drain guide 53
4 is inserted into the relay hose 51 on the inner surface of the drain pipe 19 from the lower end opening of the drain pipe 19 as shown in FIG. At this time, since the insertion protrusion 54 pushes the relay hose 51 outward, the drain guide 53 is fixed to the drain pipe 19 by the elasticity of the relay hose 51. Thus, the operation of attaching and detaching the drain guide 53 can be extremely easily and smoothly performed.

The inner diameter of the drain hole 18 is equal to that of the relay hose 51.
Therefore, even if the relay hose 51 is pushed upward by the insertion of the drain guide 53, there is no danger that the relay hose 51 will jump out of the drain hole 18. Therefore, the positioning of the relay hose 51 is facilitated, and the structure can be simplified.

The drain guide 53 is connected to the drain pipe 19 and forms a so-called U trap inside. The wastewater that has flowed into the drainage pipe 19 is once stored in the drainage guide 53, overflows, and is discharged into the drainage tray 52 below. Further, in the embodiment, the drain guide 53 is connected to the drain pipe 19, but the upper end may be connected to a drain hose having the same structure to communicate with the drain tray 52.

Further, in the embodiment, the present invention is applied to a low-temperature showcase. However, the present invention is not limited to this, and is also effective when applied to a home or business refrigerator.
