Drainage joint is a unitary plastic part, it comprises fixed part, turning part and connecting portion, fixed part has the laminated structure of opening for central authorities, connecting portion is a circular tube structure, the turning part is the hollow structure with 2 ports, the edge of opening of fixed part and connecting portion end are connected on 2 port edges of turning part, the turning part is a square elbow, the one end tiltedly is connected with the edge of opening of fixed part, central authorities have the another port sealing of the flat board of circular hole with the turning part, and the connecting portion end is connected on the dull and stereotyped circular hole edge.

As optimization, the turning part of drainage joint is the two-part bend pipe, leans on one section of fixed part to be gradual change cross section rectangular tube, is connected and fixed the face area maximum of portion.

During use, drip tray is installed in the vaporization chamber of food freezer, between upper spacer and Defrost heater, drainage joint is stuck on the backboard of casing by its fixed part, its turning part and connecting portion are in the backboard of casing, and water receiving pipe is arranged in the backboard of casing, and its upper port is connected with the connecting portion of drainage joint, its lower port is connected in the evaporating pan of Machine Room, and the drainpipe on the drip tray stretches in the turning part of drainage joint.

The utlity model has following characteristics and progress:

1. the drainage rates that defrosts is fast and draining is clean, can improve the refrigeration of cold refrigerator and guarantee that refrigeration machine runs well;

2. simple in structure, reasonable in design, production cost is low, effect good.
