Abstract: An in-duct humidifier has a permeable rectangular pad to be placed in a heated air stream. Water dripping onto the top of the pad is evaporated by the air stream which is passing through the pad to thereby increase its humidity. The pad is held in a frame and the frame is mounted in the humidifier's housing. The frame holds the pad by an arrangement of sloped surfaces and narrow projections to minimize the area of the frame in direct contact with the pad. By minimizing the contact area between the pad and the frame, the amount of water flowing onto the frame and evaporating from the frame is minimized, thereby reducing the rate and amount of minerals dissolved in the water which are deposited on the frame surfaces.

Abstract: The invention relates to an evaporative cooling device including a stand-alone housing that is not connected to any structure. The housing is multi-sided and evaporative pads are placed inside the opening of each of the multi-sides. An electric centrifugal blower is placed inside the housing to draw air through all of the eavaporate pads and to discharge the same in a vertical direction through an opening in a top cover. The top cover has a directional spout placed over the opening to direct the air in multi-adjusted directions. The cooling device is intended to be used on wide open playing or sport fields or in open sided warehouses or work stations. A smaller size is intended to be used in semi-confined areas such as verandas, patios, lanais, porches etc. A flexible air duct can be attached to the spout so as to temporarily deliver cooled air to confined spaces such attics in a house.

Abstract: An in-duct humidifier has an evaporative pad onto the top of which water is dripped. Air passing through the pad evaporates the water to thereby increase the air's humidity. An improved tray for dripping the water onto the top of the pad has a sloped floor in which are a number of holes. A nozzle assembly which is mounted directly on the top of the tray and an improved arrangement of walls on the tray floor assists in delivering equal amounts of water to all of the holes, resulting in even distribution of water throughout the pad and more efficient operation of the humidifier.

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).

Abstract: A humidifier for use with counter- or down-flow furnaces such as those traditionally found in mobile homes. The humidifier includes a louvered tip-out access door, behind which is housed a drawer containing a water panel. The drawer is detachably snap-fitted to the inside of the access door. Water is directed onto the water panel by a water dispersion bar, which is snap-fitted into the top of the drawer above the water panel. As air is drawn through the humidifier which is installed over the return air louvers of a counter-flow furnace, tiny water droplets in the water panel are picked up by the moving air stream and carried into the home. The tip-out feature of the access door and the snap-fit connections allow for simple, easy repair and cleaning, even by an untrained person, thus avoiding the need for a skilled technician when only routine maintenance is necessary.
