ABSTRACT:
A water trap cup for use in connection with a drain tube in a refrigerator is described. In one embodiment, the water trap cup includes a bottom wall and a side wall extending from the bottom wall. The side wall includes retaining webs configured for retaining an end of the drain tube within the water trap cup, and a bottom stop extends from the side wall and maintains the drain tube end spaced from the bottom wall so that a seal is not formed between the bottom wall and the drain tube. The retaining webs generally define a first chamber and a second chamber, and the first and second chambers are in fluid communication. To assemble the water trap cup to the drain tube, the first chamber is aligned with the tube, and the cup is pushed upward into engagement with the drain tube until the drain tube end contacts the bottom stop.
