Abstract: A modular ceiling fan assembly and system is disclosed in which the functioning components are standardized, including standardized connections for their assembly, and multiple components are provided with a plurality of alternate parts for assembly into a variety of uniquely differentiating configurations, styles and appearance without substantially increasing the cost to the manufacturer. The motor platform, including the motor, shafts, switch housing and electrical components and wiring, are standardized into a single configuration, and the holes for mounting the fan blades on the lower surface and/or upper surface of the rotor have a standardized size and spacing. A modular motor housing is formed from multiple horizontal sections, preferably two or three, with a standardized height to accommodate the common single motor platform. The various sections of the modular motor housing are selected in order to produce a variety of uniquely different appearances.

Abstract: Ceiling fan motors which include forced air ventilation and heat dissipation systems to provide significantly reduced motor operating temperatures, improved motor component tolerances, lower manufacturing costs, and ease of assembly. The ceiling fan motor is of the inside-out type and includes an impeller mechanism associated with at least one of the upper or lower portions of the motor casing for drawing substantial volumes of air into the casing, across the stator, and through the opposite portion of the motor casing. The motor casing components may be formed from cast aluminum. Alternatively, the entire casing and rotor is of unitary integrally cast aluminum. One of the end faces of the motor casing may include integrally cast blade ramps.

Abstract: An evaporative humidifier includes a top cover and a water reservoir tank removably mounted on top of a base platform. Several of the components of the humidifier contain a biocide for resisting the growth of bacteria and fungi on all surfaces of the components. The humidifier includes, in one embodiment, a pump assembly for moving water from the base platform to the top of an evaporator panel disposed in an air stream drawn through the humidifier. Alternatively, a paper wick is partially submerged in the pool of water in the base platform for drawing water up into the air stream by capillary action.
