Abstract
Abstract A dehumidifier package for use in a residence in the form of a box having front and rear walls spaced apart and having silica gel particles bonded to the interior surfaces. End walls connect the front and rear walls so as to form an air flow channel through the box for permitting air to flow over the silica gel. In one embodiment the top and bottom of the box are open and air flows through the box through the natural draft created as the air becomes lighter and rises. In another embodiment air is forceably drawn through the box by means of a powered fan pulling air from the bottom and exhausting the air near the top. A regeneration chamber may be provided in which the bottom of the box can be positioned to communicate with a plenum chamber in the regeneration box, the plenum chamber communicating with an opening through which hot air may be directed.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
150 words
A dehumidifier package for use in a room, said package comprising a container having a front and a rear wall, a pair of opposed end walls fastened to said front and rear wall at spaced locations to form a space between facing interior surfaces of said front and rear walls, each of said walls having top and bottom edges defining the top and bottom of said container respectively, a layer of desiccant particles bonded to each of said facing interior surfaces extending into said space, the desiccant on the respective faces being spaced one from the other so that a channel is formed therebetween, means defining an opening in the bottom of said container communicating with said channel for permitting ingress of ambient air into said channel through said opening, and means forming an air exit in said container adjacent the top for permitting egress of air from said channel.
