Abstract

A humidifier (10) includes a water distribution tray (18) that functions to substantially uniformly distribute water to an evaporator pad (16) even when the distribution tray (18) is tilted and regardless of the rate of water flow. The distribution tray (18) includes a plurality of channels (100) that each lead from a liquid reception area (104) to an opening (106) in the bottom wall (82) of the tray (18). A wick (110) fabricated from a water absorbent material is carried by the tray (18) at the reception area (104). The wick (110) may extend at least partially into each channel (100), and absorbs water and pushes it into each of the channels (100) through capillary action. Thus, each channel (100) receives water even if the tray (18) is tilted. The humidifier (10) also has a damming rib (72) that prevents water from draining from the pad (16) out of the humidifier (10).
