Abstract: The present invention provides a pump for automatic and continuous emptying of water condensate from a dehumidifier positioned below ground level or remotely from a gravity drain. The present invention includes a small electrical pump powered by a 12 volt DC power source to prevent electrical shock, includes an on/off float switch connected with the power source, in cooperation with a flexible hose of small diameter of variable length. Condensate collected in the water collection pan is withdrawn at a preselected water level by the pump and passes through the tubing to an elevated or remote drain means or to other appropriate areas for disposal. The present invention permits continuous operation of portable dehumidifiers which would otherwise shut off when the condensate water pan fills after approximately one day's unattended use.

Abstract: A condensation tray includes a central main tray body formed from extruded polymeric/copolymeric material and includes a bottom wall and opposite upstanding side walls. The bottom wall includes inner and outer surfaces and condensation channels/chambers therebetween. A coil sitting upon the bottom wall inner surface operating in the air conditioning mode creates condensation from the ambient air within the condensation channels/chambers which collects therein, flows outwardly therefrom into one or two of opposite injection molded end caps bonded to the central main tray body. Condensate eventually passes through a discharge port of the end caps(s) to a drain, and in this manner condensation will not adversely effect the fan coil unit, its components, or the environs thereof, such as an adjacent rug, ceiling or the like.

The warm air current of the blower flows to an outlet hole through an air channel which is connected to an outlet connecting piece of the blower.

Abstract: A rigid plastic twist lock drain funnel for conveying defrost water from the interior of the refrigerator cabinet, through the insulation space, to the exterior. A top portion of the funnel has a groove seating an O-ring, and a central portion has a pair of radially extending cam-shaped ears. During fabrication, the drain funnel is inserted from inside the refrigerator liner through an aperture having notches for receiving the ears, and then the funnel is twisted approximately 90.degree. to engage the ears as a cam lock.
