The condensed water formed on the return air cover 102 is guided by the inclined sections of the return air frame 1021 and the return air rear cover 1022, flows along the front guide inclined section 133 to the horizontal straight section 134, and is finally discharged through the water outlet. The condensed water on the evaporator 101 flows to the horizontal straight section 134 along the front diversion inclined section 133 and the rear diversion inclined section 135, respectively, and is discharged through the water discharge port.
A drain (not shown) is connected to the drain, through which the condensed water is directed into an evaporation pan of the refrigerator 100, which pan may be generally located in the compressor compartment for evaporating the water therein by means of the heat of a condenser and/or a compressor arranged in the compressor compartment.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
