The refrigerator needs refrigeration in operation, so the surface temperature of the evaporator will be very low, below zero. The air in the refrigerator contains moisture. When air meets a cold evaporator, it will condense water, just like the glass window in our house in winter. If the water is not treated, it will flow to the ground, causing pollution and damaging the floor and other electrical appliances at home. This phenomenon mainly occurs in cold rooms.

Therefore, in the design, a pipe is installed in the sink of the refrigerator, which leads to the bottom, and a water receiving tray is installed above the compressor at the bottom, which is a box to receive the condensed water flowing down from the top.

When the compressor is running, it will generate heat, which will heat and evaporate the water in the water pan. Don't pile up too much and flow to the ground.

In this way, a kind of circulation is formed, which eliminates the constantly generated water and ensures the normal and safe operation of the refrigerator.
